Managing Human Resources free essay sample

This assissment is going to be about Human Resource Management and it’s going to contain information about different perspectives of human resources management and what the role involves. . HRM system is based on HR system , both work together to the same way. The example is HR strategies defining the direction in which HRM intends to go. We got few models of HRM , one I want to describe is Guest’s Model of HRM. David Guest’s model of HRM has 6 dimensions of analysis : HRM strategy HRM practices HRM outcomes Behaviour outcomes Performance outcomes Financial outcomes This model is prescriptive in the sense that it is based on the assumption that HRM is different from traditional personal management. How guest’s model is adopted in Harrods? In my opinion is adopted by having similar commitments for example the Guest model is prescriptive on the sense that it is bases on the assumption that HRM is distinctively different from traditional personnel management and rotted in strategic management. We will write a custom essay sample on Managing Human Resources or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Also the Guest’s model of HRM outcomes are fairly similar as Harrods engages employees to continues success of the business by committing to what they are doing and one of the outcomes that the Guest’s model states is commitment. David Guest’s analysis financial outcomes in his model of HRM and when looking at the financial outcome at Harrods, we can see that they are loosing money due to the employee turnover. When looking at the case study it shows that the research that has been done about the turnover indicates that the employee turnover has significant cost and performance effects to the business. For example the employee turnover at Harrods measures the rate at which employees leave their employer normally after one year. The claim of the Guest model that it is superior to others is partly justified in the sense that it clearly maps out the field of HRM and delineates the inputs and outcomes. But the dynamics of people management are so complex that no model (including the Guest model) can capture them comprehensively. P. 1. 2 The purpose of HRM is to ensure that the employees of an organization are used in such a way that the employer obtains the greatest possible benefit from their abilities and the employees obtain both material and psychological rewards from their work. Personnel management is the traditional approach to managing. It deals with the reactive side, which are rules, and regulations, wages, pension, and leave administration. It is administrative in nature. Human Resource Management are people oriented an treats employees as an asset. It is the modern approach to managing an organisation and people in the organisation. It is the proactive side of managing which puts people first. The term industrial relations has developed both a broad and a narrow meaning. Industrial relations is increasingly being called employment relations or employee relations because of the importance of non-industrial employment relationships. Industrial relations has three faces: science building, problem solving, and ethical. In the science building phase, industrial relations is part of the social sciences, and it seeks to understand the employment relationship and its institutions through high-quality, rigorous research. From this perspective, an industrial relation covers all aspects of the employment relationship, including human resource or personnel management and employee relations. The difference between personnel management and human resource management is that personnel management basically deals with the employees, for example they deal with payroll recruitment. Where the HRM deals with the management of the work force, training and the well-being of all employees. Also we can say that Human Resources is to incorporate and develop personnel management tasks, while at the same time seeking to create and develop teams of workers to the advantage of the organization. Personnel management comprises mainly of administrative tasks that are considered to be traditional and routine. The Human Resources management at Harrods helps to build a competitive edge by positively getting involving the employees. The HRM at Harrods use an appropriate leadership style and they use two-way communication, which is very effective as it allows information to be passed on correctly and quickly. Similar organization which adopted IR practice and Personal is NHS. The NHS UK practice managers work within the primary care sector, where they manage the overall running of general practices surgeries. Practice managers come from a variety of backgrounds and do not necessarily need to be a qualified healthcare professional. Industrial relations in the UK health care sector are characterised by high levels of social dialogue and joint regulation, particularly in the public part of the sector. P. 1. 3 At Harrods the role of the line manager is to encourage communication targets and advice to employees through face-to-face interactions. This might involve sitting down in the staff room, or in a more formal setting, to agree objectives and to give advice about improvements and new ways of working. Acting as a coach helps the line managers to develop their managerial skills, build relationships and reinforce trust at Harrods. Employees play the most vital role in HRM because they are the key advantage and we also must remember that high-performing and innovative employees are the foundation of productivity. Some major implications for HRM are, they can set direction and implement a company strategy, which builds commitment to what they do. Employees at Harrods help to develop performance metrics for on going improvements in the business. In order to increase the productivity at Harrods the line manager or HRM support their employees by communicating effectively and giving them regular feedback on their performance and by them doing that it decreases the errors and frustration caused to employees at work. Also an effective reward system for employees at Harrods motivates them towards better performance. Non-monetary factors like better status can motivate employees in addition.

Globalisation essays

Globalisation essays In the past few years, one of the most controversial economic issues has been global free trade. The proponents claim that nations engaged in open trade would experience a great deal of economic growth. Opponents think that giving foreign countries unrestricted access to American markets will cause a decrease in the number of American jobs, and will pose a threat to American sovereignty. It is the opinion of this writer that the latter is correct. The problem with global free trade is really fourfold. The first and foremost problem with such measures is, as stated above, the threat posed to American sovereignty. All free trade agreements set up international bureaucracies to govern the participants; to ensure that all parties comply with the terms of the agreement. Vice President Gore tried to allay the concerns of the opponents of GATT by claiming that the World Trade Organization would hold no authority over the U.S. He claimed that we would only be bound by those rules which we agree to and no others. However, in his very next breath, he claimed that other countries could be forced to comply with their "international trade obligations" (Gore). Clearly, this is a complete contradiction. No contry, except perhaps the U.S., would agree to so obvious a double standard. Newt Gingrich is at the opposite end of the political spectrum from the Vice-President. Of GATT, he once said, "... we need to be honest about the fact that we are transferring from the United States at a practical level significant authority to a new organization... I would feel better if the people who favor this would just be honest about the scale of change." ("How Can") However, despite his own concerns, and the victory he was handing his political opponents, he publicly supported and voted for GATT. Self-flagellation seems to be a hobby of these people. The second problem deals with the market size. How does the size of the market in the U.S. compare with ...

A Telephone Based Wireless Remote Controller

Data processing stages of the transmitter and receiver modules have been implemented using digital components, thereby avoiding possible use of conventional devices like monostable multivibrators. Due to the fully digital nature, the proposed design is less complex and hence the implementation is cost effective. I. INTRODUCTION With the advancement in science and technology, human beings have developed a tendency to make their everyday life amply luxurious with the aid of technology. This has led to the development of many sophisticated gadgets and equipments that assist them partially/fully in their daily activities. Operating all such electronic/electrical instruments in a modern house might be difficult for the elderly as well as disabled people. Our primary motivation to build a simple and low cost system which remotely operates all the home appliances stems from this point. We integrate our system with a standard telephone set so that the telephone can be used for the dual purpose of telephony and remote controller for various home appliances. The proposed system mainly consists of 3 modules, viz. , telephone interface circuit, transmitter and receiver. The transmitter module is in turn made up of a digital data processing block and a wireless (infrared) transmitter block and the eceiver module is made up of a wireless (infrared) receiver block, digital data processing block and a decoding block. In the scheme, a telephone receiver acts as a remote terminal to provide input Dual-Tone Multi-Frequency (DTMF) signals to the telephone interface circuit which converts them to corresponding 4 bit Binary Coded Decimal (BCD) codes. The transmitter generates an 8 bit frame using this BCD code to facilitate asynchronous communication . The receiver decodes the received signals after checking for any transmission errors (single bit) in the frame. These decoded bits act as control signals for the operation of home appliances. The system employs an asynchronous type of communication [1] in which the transmitter and receiver clocks are independent. The receiver clock does not have any prior information regarding the phase of the transmitter clock [2]. This leads to the problem of choosing the correct sampling instants at the receiver [3]. Hence the data is transmitted in the form of frames instead of individual bits. Each such frame consists of start bits, information bits, and stop bits [1]. This is explained in detail in the subsequent sections. When the system is idle, the data processing block of he transmitter gives constant logical high output. Since the transmitter consumes more power in transmitting logical high than logical low, the output of data processing block is negated before transmission to save power in the idle state. The receiver module also senses this and remains idle whenever the transmitter is transmitting continuous logical low. The reception of a start bit changes the state of the r eceiver from an idle to an active state. It then has to sample the remaining data bits in the frame at proper sampling instants. Most of the standard hardware schemes involve the use of monostable ultivibrators at the receiver to recover the data bits following the start bit. The monostable multivibrators commonly rely on variable components such as resistance and capacitance values, as well as they often account for a major part of the propagation delays associated with the receiver. We have extended this treatment to a fully digital design that presents more challenging tasks including a digital output feedback. Moreover, use of all digital components in the data processing stages reduces the propagation delay considerably. The complete design outline of all the modules of the roposed system is presented in Section II. Results and discussions are given in Section III. Finally, we present our conclusions in Section IV. II. DESIGN OUTLINE The block diagram of the proposed telephone based wireless remote control system is shown in Fig. 1. In the proposed system, the telephone set performs the dual functions of telephony and remotely controlling various devices. The remote control mode of the telephone can be activated by pressing ‘#’ from the keypad of the telephone. After the desired tasks are accomplished, ‘#’ should be pressed again to deactivate the control system. This is one of the functions of the telephone interface circuit, which is discussed next. A. Telephone Interface Circuit The telephone interface circuit integrates the designed system with the standard telephone system. As shown in Fig. 2, it basically performs the job of receiving the signals from the local loop and converting them to the standard digital signals in the BCD format. When any telephone button is pressed, a unique DTMF signal is produced for a short duration [4] which is converted to corresponding BCD code by a standard DTMF to BCD converter (KT-3170) [5]. The dual tone frequencies and the BCD codes associated with each dialed digit are shown in Table 1. The system remains in the idle state until ‘#’ button is pressed which sets the telephone to remote control mode. This mode remains activated until ‘#’ button is pressed again. This is realized in the hardware by using the BCD code corresponding to ‘#’ as the clock to toggle the J-K flip-flop (74112). The flip-flop output toggles whenever the ‘#’ button is pressed and this is directly used to control the mode of operation of the telephone. The DSO output of KT-3170 [5] is used to generate a start it for the system as it is logical high whenever a received tone pair has been registered and the output latch is updated. As the latched 4-bit BCD code is directly available at the output of KT-3170, it is given as such to the data processing block of the transmitter. These data bits are then processed to facilitate asynchronous communicatio n as explained below. B. Transmitter The 4-bit output of KT-3170 can not be directly transmitted as individual bits as the proposed system employs asynchronous mode of communication. The 4-bit BCD code is thus transmitted as frames for proper reception [1]. We have chosen an eight bit frame for our system which consists of a start bit followed by four data bits, a parity bit and two stop bits. Parity bit enables the system to detect any single bit error during transmission. Stop bits mark the ending of the frame. The frame is then transmitted using infrared (IR) transmitter. As shown in Fig. 2, the transmitter mainly consists of two blocks which are explained below. 1) Fully Digital Data Processing Block: This block performs the function of converting individual bits to 8-bit frames in order to carry asynchronous communication. First bit of the frame is the start bit (taken as 0) which is generated when any of the buttons is pressed. The succeeding 4 bits are the data bits (BCD code) generated by the telephone interface circuit as explained before. Next bit is taken as parity check bit generated by XORing the first 5 bits of the frame. Last 2 bits, termed as stop bits, are taken as 1. Following the generation of the start bit, the data bits are loaded in the parallel to serial converter (74165) using a D-type flip-flop (7474) and the frame is transmitted serially. 2) IR Transmitter Block: This module transmits the frames enerated in the previous section using an IR emitting diode. The data to be transmitted is modulated using Amplitude Shift Keying (ASK) with a carrier square wave of 38 kHz. The transmission range of the system is thus highly improved over the case when data is transmitted without modulation. As the data processing stage gives logical high output in the idle state, it is negated before tran smission to save power. Thus, a logical low is actually transmitted whenever the system is in idle state. C. Receiver The receiver also has 2 working states, viz. , idle and active. It remains in the idle state until it detects a start bit. It then receives the frame starting from the start bit and checks for a single bit error. If error is detected, no action is taken and the information has to be transmitted again by the user. The received data bits are then decoded which act as control signals for the operation of various appliances. As is evident from Fig. 3, receiver circuit can be subdivided into 3 blocks which are explained below. 1) IR Receiver Block: This block receives the transmitted frames and converts the signal back to Transistor Transistor Logic (TTL) levels. A standard 38 kHz IR receiver (TSOP 1738) [6] is used for this purpose. 2) Sampling Clock Generator: The main function of this block is to generate a sampling instant at approximately the middle of the transmitted bit interval. The start bit activates this block and loads counter 1 (4-bit up-counter) with value ‘0’. The clock frequency of this counter is 16 times the bit rate. When the output of this counter changes from 7 to 8, the most significant bit changes from ‘0’ to ‘1’ and this rising edge is used as the sampling instant for the data. Start bit also loads the counter 2 (4-bit down-counter) with the frame size i. e. , 8. When this reaches the value ‘0’, the whole block is disabled and is reactivated only when next start bit arrives. 3) Data Sampler and Decoder: The serial input data is sampled according to the sampling instant generated in the previous stage and is converted to parallel form using serial to parallel converter (74164). This data is then checked for any 1-bit errors by XORing the bits. If error is found, no action is taken and the data has to be retransmitted. If no errors are found, the data is decoded using 4-16 decoder (74154) and he signal is given to the appliance for the completion of the corresponding task. III. RESULTS AND DISCUSSIONS The proposed system has been fully implemented and successfully tested in the standard telephone local loop. The transmitter, kept near the telephone set, taps the DTMF signal from the local loop and transmits the corresponding data frame wirelessly . This signal is received by the receiver installed at the switch board. It decodes the data and takes the corresponding action. At least ten control signals, corresponding to each digit from 0 to 9, can be generated using a standard telephone set. The transmitter was previously implemented without a modulator where the IR LED was kept ON for transmitting logical high and OFF for transmitting logical low. This limited the distance between the transmitter and receiver to a maximum of 30 cms for proper reception. The range of the wireless system has increased to several meters after modulating the data using 38 kHz square wave. This range also depends on the current flowing through the infrared diode which has to be properly tuned to maximize the range. A standard TSOP 1738 receiver is used in the proposed ystem, which requires a minimum burst length of 10 cycles for proper detection. This puts an upper limit on the data rate supported by our system which is practically observed to be 2. 8 kbps [5]. The IR transmitter is highly directional and requires the receiver to be in line of sight of the transmitter. The reception angle of the receiver is observed to decrease with increasing distance between the transmitter and receiver. T his is because of the fact that the power is not uniformly distributed and is concentrated in narrow transmission angle. Moreover, the signal power reduces when the distance between the transmitter and the receiver is increased. So, the receiver has to be highly aligned with transmitter when operating at some substantial distance from it. This problem is of not much concern for our system because the transmitter and receiver, being static in nature, can be properly aligned at the time of installation. The data processing blocks of both the transmitter and the receiver are fully digital in nature. This comprehensively reduces the propagation delays involved and increases the rate at which data can be processed in these blocks. Though, data rate is not very important in the present application but this feature makes the design of our data processing blocks suitable for high data rate applications which are commonly seen in wired communication. IV. CONCLUSIONS A wireless system has been proposed to operate the home appliances remotely using a standard telephone set. This has been successfully tested and is found to be working satisfactorily within a distance of 10 meters. The telephone receiver performs a dual-function of telephony and remotely controlling various devices with the help of its ‘#’ button on the keypad. The telephone interface circuit is easily integrated with the standard local loop thus avoiding any changes in the telephone set. Hence, the proposed system is compatible with any type of telephone working on standard local loop. The system employs asynchronous mode of communication which avoids the need to synchronize the transmitter and receiver clocks, thus making our system less complex and hence cost effective. The proposed fully digital innovative design of the data processing blocks reduces the propagation delay and makes them useful for even high data rate applications. Moreover, the system is capable of detecting the single bit errors occuring during transmission. The proposed system can be used in a wide range of practical applications such as speed control of motors, switching of appliances, control of robots, etc. The above discussed characteristics like simple design, high practical utility and easy installation makes our system highly marketable.

Dwarf planet Essay Example | Topics and Well Written Essays - 500 words

Dwarf planet - Essay Example sume the spherical shape and secondly, they have not yet established a debris free orbit in their solar system and thirdly, they must not be satellites for other planets. Further, if the celestial object in question is too small to take the rounded spherical shape, it would probably be classified as a comet or an asteroid. In our own solar system, there are several objects that fall under this category of planets. The introduction of this new category of celestial objects was prompted by the recent discovery of Eris – a disc shaped cluster of debris that was located far beyond the orbit of Pluto. The other notable dwarf planets in our solar system are Ceres and Pluto. Ceres was for previously recognized as the largest asteroid and Pluto is demoted to dwarf planet status considering that its orbit is not as well established as other planets. It is interesting to note that these three are only the most prominent dwarf planets in our solar system. There could be as many as 200 orbiting in the outer reaches of our solar

Horny Goat Weed Essay -- Sexuality Disorders Treatments Essays

Horny Goat Weed One major issue in the world today is sexuality. Do I look good enough? I wonder if he or she likes me? While most of the world today is becoming increasingly sexually active, there are others are out there who are lacking in this field. Their bodies are no longer inclined to have or sex, or their sexual drive loses the battle between time and fatigue. Horny Goat Weed is said to be the cure of this "problem." Horny Goat Weed, also known as Epimedium, Yin Yang Huo, Inyokaku, and Herba Epimedii, was discovered around 200 B.C. Legend has it that an ancient Chinese goat herder noticed that his flock suddenly became sexually active after eating in a certain patch of weeds. Further investigation of this weed patch and a little leaf chewing resulted in the discovery of Horny Goat Weed (http://www.sobebev.com/healthyrefreshment/ productline/drive.htm). Purpose of Treatment There are many different claims as to what Horny Goat Weed actually does. Online stores and distributors, which are more focused on marketing the herb for increased sexual behavior, main claims are stimulating sex activity in both men and women, increase in sperm production, stimulation of the sensory nerves, and increasing sexual desire(http://nutrition-center.net/store/Pinnacle_Horny_Goat_Weed.html). Online sites, which appear to be more focused on health, make claims that Horny Goat Weed invigorates the kidneys and strengthens yang(for deficiency of kidney-yang manifested as impotence, emission, enuresis, frequent micturition, soreness of the waist and the knees, and sterility), strengthen tendons and bones, expel wind-dampness(which is otherwise known as flatulence, caused by the improper indigestion of food), and eliminate coughing and ... ...t/store/Pinnace_Horny_Goat_Weed.html http://homepages.infoseek.com/~huxuezhi/5-17.htm http://herbwalk.com/remedy/Epimedium_132.html http://advancedherbals.co.uk/herbs/div/epimedium_grandiflorum.html http://user.aol.com/greenmagik/stamina.htm WS, Lin, & XZ, Song.

Partners Healthcare Case Aanlysis Essay

Partners Healthcare had established several financial resources pools, such as the short-term pool (STP) and the LTP, so that they can satisfy different needs of the several hospitals in the network. In more detail, the STP was invested with very high-quality, short-term fixed-income financial instruments. The average maturity of these instruments is about one to two years. STP is always treated as the risk-free part of the hospitals’ holdings. On the other hand, the LTP is thought as the risky part of holdings. It consists of different forms of equity and a smaller fixed-income part. In order to diversify the risks of the LTP, the Partners Investment Committee introduced a new type of assets, real assets, into the original LTP during the past years. Both of the assets’ performance turned to be excellent during 2004. As a result, the Investment Committee was considering expanding the real-asset segment of the LTP. Michael Manning, the deputy treasurer of Partners Healthcare System, was asked to recommend the size and the composition for the real-asset portfolio contributed to the $2.4 billion long-term pool (LTP) in the Partners. Facts and Analysis Due to the fact that different Partners Healthcare hospitals might have different acceptable risk levels for their investment portfolio then the most reasonable solution would be to invest both in risk-free STP and risky LTP. By choosing different mixes each hospital could achieve their acceptable risk level. Since the STP has a nearly fixed rate of return considered to be risk free for each hospital’s own portfolio, the variation from LTP would ultimately determine the risk and return level of individual portfolio. Using long-term historical data, Manning and his staff calculated average annual returns, volatilities, and correlations for each of the asset classes (exhibit 3). Since real assets belong to LTP, there is no direct impact on the STP returns from investing in this category. Given the current mix of Domestic Equities (55%), Foreign Equities (30%) and LT Bonds (15%) and our expected return for each category (exhibit 3), the expected return of the LTP is calculated from the following formula: e.g. E(Rp)= 0.55(0.1294)+0.30(0.1242)+0.15(0.054) = 10.8% In order to find the optimal portfolio allocation, the group needs to find the portfolio structured with lowest risk under a given return. This can be achieved by applying Mean-Variance Theory and Markowitz model find the efficient frontier, which yields the most optimal portfolio under given returns. It can be expressed in mathematical terms and solved by quadratic programming. [Appendix A] In this case, the Partner’s Treasury Department has computed all the portfolios for minimum level of risk with different types of assets, more specifically, adding Real Estate Investment Trusts (REITs), Commodities or both, from an undefined approach. Since the results are identical as calculated from Mean-Variance Theory, they should be the optimal portfolios for each target level of return. Therefore a graph with efficient frontier, which represents the optimal portfolios with different assets, is constructed based on Exhibit 5 to 8 for comparison. [Appendix B] Technically, any portfolio on the efficient frontier is an optimized portfolio and is indifferent from each other in terms of risk/return trade off. From the Risk VS Return graph, we can see that for any given return, the portfolio with both REITs and commodities would yield the lowest risk. Also, the portfolio with only commodities would outperform the portfolio with only REITs. For instance, if we invest in both REITs and Commodities, in order to obtain a return of 10%, the new proportion of the LTP will be portfolio 4 with approximately US Equity 14.3%, Foreign Equity 27.5%, Bonds 22.2%, REITs 13.8%, and Commodities 22.3%. It produces the lowest risk of 8.49%, comparing to original portfolio of 9.94%, REITs only portfolio of 9.69% and Commodities only portfolio of 8.49%. This is the basic concept of diversification, which means that the more assets with less correlation are introduced to the portfolio; the less risky the portfolio will be for any achievable rate of return. [1] For the overall portfolio, each hospital can allocate between the STP and the LTP. In fact, they can always construct the most efficient portfolio for their acceptable risk level with combination of LTP, which holds the risky assets, and STP, which holds the risk-free asset according to The One-Fund Theorem. [2] For example, if the shareholders want a total return of X, with a 3.2% return of STP and a 10% return of LTP, the proportion of STP and LTP can be obtained through X= w(0.032) + (1-w)(0.10) And it is guaranteed to be the optimal portfolio. Even though Mean-Variance theory can allocate the most optimal portfolio, there are several flaws with its assumptions. First of all, it assumes that assets returns are normally distributed. However, often times, it’s observed that asset returns are more like to be fat-tailed distribution, [3] instead of having thin tails like normal distribution. Second of all, it assumes there is a constant correlation between different assets. However, under certain conditions, for example, severe financial crisis like 2008, all assets tend to be positively correlated with decreasing rate of return. Depending on the total time period used for historical data, it can place an impact on the long term correlation. Aside from the assumptions, the time period of data can also affect each variable. In this case, the client uses data started from 1970 for the new asset classes, which might not be as representative as using long term historical data from 1926 as they did with the US equities and US long-term bonds. This can have some impacts on the returns, standard deviations, and correlations depending on the movement of assets from 1926 to 1970. Recommendation By comparing the data in the table of Exhibit 5a with the numerical results shown in Exhibit 6 and Exhibit 7, as well as the efficient frontier constructed, we can derive the conclusion that with the same expected returns, the most optimal portfolio is to add both REITs and commodities. In other words, we can control the risk of LTP by expanding the portion of real assets. If only one asset is allowed to be added to the real asset category, it’s more efficient to add the commodities than the REITs based on the position of the efficient frontier. Therefore, with a combination of risk free STP and the improved LTP, each individual hospital is able to construct the most optimized portfolio under any given risk level.

Gender Biologically Determined Essay

Drawing upon ethnographic examples from 2-3 societies. Gender being ‘biologically determined’ means that whether gender is inherited or passed down by genetics. If a person is a man or woman, (which is usually called ‘The Sex’), that is biologically determined because they inherit the chromosomes to be born a man, or to be born as a woman. In the early 1970’s sex was described by â€Å"biology as: anatomy, hormones, and physiology† (West and Zimmerman 1987). Apart from gender being a biological factor, there are other things which are not biologically determined; â€Å"Gender was an achieved status, which was constructed through psychological, cultural and social means† (West and Zimmerman1987). Hence the answer to the question â€Å"is gender biologically determined?†Is no, Gender is a socially constructed phenomenon. Gender refers to a set of roles people perform in their communities, which are their values and attitudes that people have toward man and woman (Bonvillain 2006). In this essay, the topics which would be discussed to support this argument are Gender Identity with examples of how men and women are expected to act, walk, talk and dress in a certain manner which is suitable in their society, Gender and Sexuality with the examples of culturally in-built norms of sexual behaviour, along with existing issues surrounding sexuality, and finally Gender and Status with an example of male dominance in Traditional Chinese society. Gender identity is defined in terms of how people (i.e. men and women) are supposed to behave in the social category. Their attitudes and the way the dress, talk and carry themselves in the public are encoded â€Å"in a set of cultural assumptions† which are based on the culture’s values and roles and people are expected to learn these as they are a part of that society (Bonvillain 2006). Each culture has certain ‘norms’ for gender and these ‘norms’ vary from culture to culture, most of these norms have a universal common pattern and people seem to dwell on these social constructs as they make a living based on these ideologies. â€Å"Cultural constructs are models of behaviour and attitudes that a particular culture transmits to its members. These constructs are shared beliefs and values that become taken for granted guiding principles† (Bonvillain 2006). There are so many ways that these socially constructed behaviours are exhibited in different communities, the messages about how each man and woman should act depends upon several factors such as language and religious beliefs. Men and Women were distinguished based on their clothing, what they were allowed to wear as a man and woman, hence publically signalling their genders, men wore pants and had other bodily arts such as tattoos while woman adorned dresses, jewellery and make up. This made up the very basic structure of Gender Identity. Apart from, the basic examples of gender identity, there are several other cases where women and men have unequal identities, one such case is the, Identity inequality of men and woman in family farms. In today’s world, Gender revolves around being the fact that women are less recognised than men, and are subjected to work which are in the shadows of confinement. That being the generalised factor, the study of the ‘European family farm’ only made this issue recognizable to the world. Farms were considered to be the dominant agricultural production in the capitalist countries (Brandth 2002). The study used theories of gender role and identity, explaini ng the issue in the form of discourses. In the 1990’s questions were being raised towards identity of women and men in the rural farms, these questions eventually shifted towards feminism (Brandth 2002). â€Å"Discourses are forms of power. They constitute minds, bodies, identities of individuals as parts of wider networks of power relations† (Brandth 2002). It was used in the context of giving out a meaning towards the differences of men and women, there were three discourses formulated by Hirschman, called as the exit, voice and loyalty. Women, who didn’t want to be subjected to unequal status left the system, some used their voice to protest against it, while others simply were loyal and confined themselves to the household activities. The law stated that the ‘family farm’ should be passed on from father to son, since women were considered weak and have no access and knowledge of property and agriculture. Women only came into this, only by marriage. Hence, the male leads the family into it, he allocates what job has to be done, and he participates in forums decisions, and doing so he becomes publically recognised. Since women are adaptable and flexible, their tasks are confined to household chores, and these tasks are unpaid and not recognised as productive output from them. On the other hand, men’s identities were tied to their ownership of the farms, their occupation and the productive outcome which give them status and economic income. â€Å"Real work was equated with physical tasks and women’s self image is based on the absence of such qualities† (Brandth 2002). In recent days, with the improvement of farming technologies, the female work, such as milking cows, and so on are now being done by these improvised machines, making women less efficient and thus making farming a whole masculine activity (Brandth 2002). Hence with this example it is clearly pointed out that the social construct differentiates an d distinguishes men and women. Apart from gender being differentiated by a social construct, there are factors which raised questions and studies in the society, one of such being gender and its relation to sexuality. There is always a taboo when it comes to sex, and it seems to be a common pattern in the world. Even though, we have sexual feelings and we practice them as it being a part of nature, it is also deeply influenced by culture (Bonvillain 2006). Culture teaches people what is the right thing to do, in what way, when, where and so on. There are a lot of examples where culture intervenes and states the ‘norms’ under which the people in that society or community should behave sexually. For example, sexual relationship between members of a nuclear family or distant relations is prohibited in most cultures. There are other countries which have the legal age of having sex, which are usually the Americans and Europeans, where the legal age is 16, so if a person indulges in a sexual relationship wi th a person who is below 16 it is considered against the law and will be filed for statutory rape (Bonvillain 2006). Other regions such as India, sex before marriage is considered as sin based on the cultural beliefs, whereas in American society it is inappropriate to have sex if you’re not husband or wife (Bonvillain 2006). While in some countries where sex could be considered as normal, other societies, like Islamic countries for example, any adultery committed by a male or by a female is severely punished, or most commonly stoned to death (Bonvillain 2006). But this isn’t the only issue considering sexuality, the most recent yet shocking development, is homosexuality between men and woman. â€Å"Homosexuality was considered to be a violation of the natural law† (Bonvillain 2006). People were only meant to engage in heterosexual activity (between man and woman) to reproduce. During the 1980’s indulging in homosexual activity was considered in crime, people were imprisoned when caught doing so. But in 2003 some parts of the United States, suspended the law, and made hom osexuality legal, soon European countries such as Canada, Belgium, and Netherlands passed an act which approved of homosexual weddings (Bonvillain 2006). If one digs deeper into this issue, where these debatable, one can find that it roots back from religions. Most religion disapprove of homosexuality but in religions such as Hindu, for sexuality, scriptures of homosexual activity only stated that it was normal and natural, to be attracted to the same sex (Bonvillain 2006). But in today’s society the main issue is regarding the issue of males being attracted to each other, an example of this issue is ‘Homophobia of men’. Homosexuality is considered to be a cultural construct, which apart from the ‘lesbian identities’ gave rise to the ‘gay identities’ (Herek 1986). It is common for normal men, to avoid influencing with homosexual men, as they fear what the public might think of them being judged as not ‘masculine’, where as its more normal for woman to associate with lesbians or homosexual women, as they are not being judged by the rest of the females (Herek 1986). Studies showed, that the social construction of gay identities meant that there was something psychologically wrong with that person, it was never attributed to the fact that homosexuality is more of a social construct than something being wrong with the individuals mental state (Herek 1986). Gay men are more scared to come out, or feel comfortable about their sexuality in the public than gay woman. The reason for this is because, men look for other men’s approval to gain the status of being ‘a man’ (Kimmel). â€Å"We are under the constant careful scrutiny of other men. Other men watch us, rank us, and grant our acceptance into the realm of manhood. Manhood is demonstrated of other men’s approval. It is other men who evaluate the performance† (Kimmel). As mentioned earlier, men look for other men’s approval, and because of this gay men are subjected to stigma and discrimination (Herek 1986). As a result, they develop ‘defensiveness,’ an unconscious defence mechanism (defined in psychodynamic terms). This helps them avoid or repress their homosexual tendencies (Kimmel). To summarise, gender is not biologically determined because people have the free will to choose their sexuality (i.e. they are not born being homosexuals, it is clearly a social construct). Gender roles, is defined as a set of rules or rather guidelines towards the behaviour of men and woman. The rights and duties, attitudes and behaviours of men and women constitutes of how they are culturally associated with gender (Bonvillain 2006). The works of men and women are separate, as in, men carry on doing work which they are culturally supposed to be doing and women do their work, based on what the norms of cultures tell them to do. When these two norms interact with each other, they reflect a lot of differences and changes in status, prestige and power of men and woman this is called as ‘gender relations’ (Bonvillain 2006). It is obvious that men are thought to be more superior to women as they are more power driven and physically stronger than woman. While, men get more prestigious and leadership jobs, woman are confined to their homely duties of being a house-wife or in other words a care- giver (Bonvillain 2006). This brings about the inequality of men and woman. There tasks which categorize what woman are capable of doing such as, caring for children and their husbands, cooking food, making clothes and other homely chores, while men on the other hand do more physical and dangerous tasks such as, hunting animals, conducting warfare etc, this is called division of labour (Bonvillain 2006). Gender and status are the most recent conflict and the most studied topic in today’s society. Gender equality, happens when both the male and female agree to equal rights and behaviours. Gender inequality happens when the male and female do not agree to equal rights, attitudes and behaviour (Bonvillain 2006). An example of this, is male dominance in china, the male adult, was the head of the family and they expressed their dominance over their children and wives. Traditional Chinese cultures had more Patriarchal gender relations (Bonvillain 2006). In conclusion, the question â€Å"is gender biologically determined?† is incorrect, even though gender has a biological definition, gender is mostly socially defined in this context. The tasks or norms which each gender (i.e. male and female) is supposed to perform in the society, is based on a social construct. They are not born to be who there are, instead these social constructions are in-built within them since childhood. Since they taught to act and behave in a specific way which is culturally approved. They choose to be what sexuality appeals to them and what each individualistic gender they are taught to be. Hence ‘Gender’ is strongly driven by culture. REFERENCES: West,C and Zimmerman, Don. 1987.

What Causes Schizophrenia essays

What Causes Schizophrenia essays What causes schizophrenia? This is an area of great debate. It is probable that there are a number of different causes. The purpose of this writing is to outline some of the different explanations on what causes schizophrenia and to compare these in light of the nature of the evidence found. Lefton (2000) suggested that the term schizophrenia came from two Greek words which mean split mind, where as the spilt aspect refers to the fragmentation of the thought processes. Although the exact causes of schizophrenia are not known, it appears that several factors increase a person's risk for the illness. These factors interact with one another to influence the development and the course of schizophrenia (Weinberger Scientists are studying genetic factors in schizophrenia, although is has not been proven beyond doubt that schizophrenia is a disease entity which has just one single cause, but has a range of causes (Jackson, 1960). This is sometimes why schizophrenia is referred to as schizophrenic psychoses (Jackson, 1960). The evidence for genetic causes has been obtained through many family and twin studies (Jackson, 1960). Weinberger and Hirsch (1995) suggested that People who have a close relative with schizophrenia are more likely to develop the disorder than are people who have no relatives with the illness. For example, a monozygotic (identical) twin of a person with schizophrenia has the highest risk 40 to 50 percent of developing the illness. A child whose parent has schizophrenia has about a 10 percent chance. By comparison, the r ...

Assignment 6 Essay Example | Topics and Well Written Essays - 1750 words - 1

Assignment 6 - Essay Example This wildfire also resulted in the death of 86 people. This wildfire was so devastating that it prompted the Congress to set aside funds to assist the National Forest Service prevent and fight wildfires. Despite the measures that have been put in place to prevent wildfires, the U.S. still, continue to suffer from the effects of wildfires. Causes of Wildfire Both human and nature are responsible for wildfires witnessed in the U.S. According to Hamilton (2010), about 90% of wildfires that burn the U.S. forests and lands are started by humans. Firstly, arson attack is responsible for most wildfires in the U.S. Arson attacks happen when an individual deliberately starts fire with the aim of destroying the land of a person perceived as an enemy. In 2010 alone, the U.S. fire department reportedly responded to about 260,000 wildfires intentionally started by arsonists (The National Fire Protection, 2013). These intentional fires resulted in at least 390 deaths, and left at least 1,340 peopl e with serious injuries. The fires also resulted in the destruction of property worth $1.2 billion. In fact, the wildfire that burnt more than 147,000 acres of land in Southern California in 2009 was caused by arson, according to the U.S. Forest Service report (CNN, 2009). This wildfire also destroyed many homes in the northern part of Los Angeles. Most wildfires in the U.S. are also caused by people burning debris. Most people in the U.S. have the habit of burning debris. However, sometimes the wind ends up blowing the debris to a dry grass and forest cover resulting in massive wildfires as has been the case in Michigan. The Michigan Fire department reveals that most wildfires in the state are caused by people burning debris (Hamilton, 2010). Smoking is also blamed for the rising incidences of wildfires in the U.S., according to Hamilton (2010). It has been observed that some wildfires are started by discarded burning cigarettes. When an individual discards a burning cigarette on a dry grass or forest, this sometimes ends up triggering a massive wildfire that result in the destruction of several acres of land. A small percentage of wildfires in the U.S. are caused by sparks from moving trains, vehicle exhaust, and heavy equipment. Some of the wildfires that burn the U.S. forests are caused by nature, such as lightning and lava. Silverstein, Silvertein, and Nunn (2009) reveal that whereas 90% of wildfires are caused by humans, the remaining 10% are caused by nature. Normally, when lightning occurs, electric currents are sent to the earth’s surface resulting in wildfires. For instance, report indicates that about half of all wildfires in Florida are stated by lightning. Lightning is also responsible for about 2% of all wildfires in Michigan. Volcanic eruption is also responsible for a significant number of wildfires in the U.S. When an eruption occurs, hot magma is through onto the earth’s surface that cools down to form lava. However, when the ho t lava encounters dry grass or leaves, this sometimes starts wildfires as noted by Silverstein, Silvertein, and Nunn (2009). The physical nature of wildfires The physical nature of wildfire is very complex and depends largely on fuel type, geographical location, humidity, moisture content, temperature of an area and topography. For a wildfire to occur, the necessary elements must be available. Firstly, an ignition source
