How has the media influenced the arab revolutions Research Paper

How has the media influenced the arab revolutions - Research Paper Example The rise in the frequency of use of social media seeks to make governments accountable for their intentions and actions. It is worth noticing here that a single factor cannot lead to a revolution; actually, it is the combination of several factors and issues that paved the way for a great revolution. The social-economic factors and political factors were depressing, and that paved the way for the Arab revolution. Despite several limitations and censorship imposed on media, it has been observed that their roles have been the most crucial in the success of Arab revolution (Seib, 2012). Some of the scholars, experts and journalists have termed social media as an ‘undeniable force’ for attaining a valuable outcome. In order to assess the validity of their perception, a thesis statement has been developed in this paper. The statement can be observed as â€Å"Media have played a vital role in, and have been employed as a resource to support, Arab revolution†. It aims at identifying and analyzing the impact of media on the revolutions in Arab world. The role of internet and social media has been emphasized by Wael Ghonim, Egyptian Google executive: â€Å"If you want to liberate a society, just give them the Internet†( Storck, 2011, p.4). ... The major differences with respect to traditional media can be identified and analyzed in terms of interactivity and speed of the news. The traditional media include the use of leaflets, posters, and faxes to mobilize the people, whereas the use of digital media has enabled an audio-video interaction with the people around the world (Rugh, 2004). There is a profound role of media in influencing the revolution, especially in Arab countries such as Egypt and Tunisia. The protests in Egypt and Tunisia would not have been greatly successful in the absence of social media like facebook, twitter, and other sites. It was different media that kept provoking people and helped them to come together to bring about such revolution. Social media such as Facebook and Twitter were used intensively by people to disseminate information globally, and, apart from this, these social networking sites were used as a tool for fostering people within and outside Egypt for a great revolution (Ghannam, 2011). Social media and theory of communication â€Å"Networks constitute the new social morphology of our societies and the diffusion of networking logic substantially modifies the operation and outcomes in processes of production, experience, power and culture†( Fox, Mourtada-Sabbah, and Al-Mutawa 2006, pp. 155). When the above mentioned arguments are evaluated from the perspective of social media theories, it is found that â€Å"resource mobilization† theory is one of the most important theories of social movements. It came into existence in 1970s. According to this theory, resources such as money, time, organizational skills, political and social

To write a news release( Exxon mobile- new plan to invest 75% of profits into development of alternative energy source) - Essay Example 2008 will be the start of a new era for the energy industry and ExxonMobil will be taking the lead and showing other companies the way to do it. [Body] The world is hungry for fuel and ExxonMobil has been proud to supply oil, gas and petroleum for much needed industrial development across six continents. These services will carry on while the company and its affiliates engages in a radical transformation process over the next two decades. Their first commitment is to reduce exploration for fossil fuels in the next 10 years and explore instead alternative energy sources. The ExxonMobil world renowned research and development facilities are engaged on a rapidly expanding programme that explores every avenue of sustainable and renewable energy sources. Aside from the hybrid car types that are already well on the way to commercial success, there are plans to harness the earth’s own massive power which is currently locked into the wind, the waves, and geo-thermal sources. Many people are urging the politicians and the industrialists of the developed world to rethink priorities and create a new blueprint for energy provision. In collaboration with the government ExxonMobil is stepping up to this challenge. They have worked out a plan to invest a staggering 75% of their own profits along with some federal tax credits into the EarthSafe initiative. This demonstrates a deep commitment to the future of the whole planet which ExxonMobil sees as a far more worthy goal than short term profits. They are determined to leave a legacy of fossil-free energy provision within the next 20 years. The next generation will benefit from this exceptional leadership now, and Exxon Mobil is calling on other fossil fuel companies to join with them in this bold move. Strategic planning director Jim Witson said today that â€Å"out of these courageous beginnings a tremendous new chapter will soon be underway. We are making a historic pact with the planet, and we do

Analytical Paper Assignment (Syria and Ukraine) Essay

Analytical Paper Assignment (Syria and Ukraine) - Essay Example This paper discloses the current conflicts in Syria and Ukraine. It describes the roles of the main leading countries in these conflicts. The past events in Syria and Ukraine prove that imperialism is no longer relevant. It is no longer easier for powerful countries to increase their power by exercising control over the rest of the world. America, for instance, prefers not to intervene in the military actions of Syria mainly because they want to maintain a neutral stance, and projects a good international policy of not meddling in the affairs of other nations. The American foreign policy is such that it justifies military action if there is substantial evidence that the countries such as Syria and Ukraine pose a threat to world security. The Ukrainian geopolitical realities are quite different, indicating likely risks of cold war. There is also likelihood of power rivalry. The international law viewpoint considers Syria and Ukraine as trying to make an ambiguous case in trying to declare their sovereignty, the west thinks, yet there is a legal act that that has is valid from 60 years ago (Kristof 27). The self-determination remains inapplicable because its exercise would fragment an existing state-Ukraine. The same nation was a member of United Nations. Such world orders are now challenged by such functional considerations as climate change, sustainability, and weapons of mass destruction-and by normative contemplation connected with equity, human rights and survival of species (Cooper p29).

Do violent video games contribute to youth violence Research Paper

Do violent video games contribute to youth violence - Research Paper Example The environment plays a significant role in changing  the character of a person. What person practices severally in his or her life becomes a lifestyle that they have to live with (Cooper and Zimmerman (1). An investigation was conducted to establish a relationship between playing violence video games and the violent behavior among the youths. The study involved 161 children between the age of nine and twelve years, and 354 college scholars (Cheryl 1). The participants were picked randomly to take part in either nonviolent or violent video games. All the participants were involved in another computer game in which they were allowed to decide the punishment to be administered to the player participating in that game. The researchers gathered the details of the participants regarding their previous violence behavior. From the result of the study, it was observed that those who engaged in violent video games exhibited some form of violence behavior. The participants who were involved in any of the violent game chose tougher punishment for their opponent compared to those who played nonviolent games. Therefore, from the analysis of the study the researchers came to the conclusion that violence video games influence the youth to engage in violent behavior. The violent video games influence the characters of the participants. Playing video games engages someone’s mind and becomes biased towards a certain character in the game. The players of violence video games tend to identify with particular characters and assumes same visual standpoint (Cheryl 1). When players identify with violent characters they are likely to develop violent behavior. The players develop feelings of hunger, aggressiveness, short temper and their emotions are easily aroused. Furthermore, the players are rewarded as they move to a higher level and it occurs after subduing the enemies. The habit of rewarding players who have managed to defeat

Gender Differences in Religious Belief Essay Example for Free

Gender Differences in Religious Belief Essay Critically examine the relationship between gender, religious participation and religious organisation Studies of religious belief verify consistently that the female gender shows greater participation to religion than that of males. This greater commitment to religion described by sociologists such as Bensen applies throughout the course of the woman’s life, and as noted by Glock and Stark, their greater pledge to religion is consistent regardless of the religious organization, whether it be New Religious movements, New Age spirituality, or traditional faiths. Beit-hallahmy and Argyle state that whether it is a matter of private churchgoing or private prayer and regardless of religious belief women appear more religious than men. Religions universally have been found to be deeply oppressive to women, born from ancient teachings indicating their inferiority to men. Writers like de Beauvoir and Sadwai see religion and religious ideology as playing a part in maintaining male domination that is found in many aspects of contemporary social life. In religious scriptures women take the lesser position; De Beauvoir highlights how scriptures in most religions suggest that â€Å"man is master by divine right† and Aldridge explains how in the Qu’ran women are legally inferior to men. Why, then, do women pursue a faith which encourages their oppression, more so than the gender with the power to dominate it? Biological factors begin with Miller and Hoffman’s explanation that women take fewer risks than men and as a result seek to conform to a groups religious identity rather than undertake the challenge of authority and autonomy. Men more often reject the religious beliefs of the mainstream and engage in risk-taking behaviors. According to Stark this risk taking inclination in a man to not â€Å"think ahead† means that men are less religious because they are willing to take a gamble on there not being an afterlife. However sociologists like Freese and Montgomery debate this argument works on an assumption that everyone makes the same risk assessment when in fact men are just more prepared to take that risk. Roth produced a study which showed there to be a smaller gap between genders in the percentage who believe in an afterlife but a large gap in those who give attendance and prayer to religion, suggesting women just participate actively more than men. Armstrong states that biological differences between men and women gave way to male domination; patriarchal montheism has replaced polysthetic beliefs which promoted the role of the female in society, for which evidence was found by archeologists in the form of old statues of goddesses. He argues that natural male aggression was the tool used to manipulate religion into a patriarchal institution. The socializations built upon this biology, are of men to be strong and domineering, and of women to be passive, obedient, and nurturing, which according to Mol, are the qualities associated with religiosity. Miller and Hoffman establish that gender socialisation makes women more cooperative and caring, and this can leads to many explanations for their greater participation in religion. One is their role of guardians in family life. Bruce states that women’s child bearing and rearing experiences for instance develop their traits as nurturers as opposed to confrontational and goal seeking. Luckmann further explains that women have a greater responsibility for rearing children and participate to a lesser degree in the labor force, leaving them with more time for church-related activities and a greater need for a source of personal identity and commitment. Women are more likely to take on the task of the moral development of their child along with the rest of their duties in socializing a child. There is an expectation for women to be defenders of tradition and Halman and Draulans note that these roles give women a greater focus on the family. Luckmann also highlights how women’s role as a housewife gives them lesser participation in the labor force, leaving them with more time for church-related activities and a greater need for a source of personal identity and commitment. They are more likely to experience status frustration, born from the constraints of housework and childcare or the unsatisfying lower middle class jobs which are mainly done by women. Religious participation can reinstate identity and give women focus, because where men gain individuality through work, women revive their low sense of worth through religion. Religious faith and practice can enhance psychological well-being by being a source of comfort to women in times of distress and by enhancing their social interaction with others in places of worship. More responsive and sensitive personality traits in a woman mean they are more likely to contemplate emotional wellbeing and not only seek solace in religion bit find meaning and purpose in life. Personality was be attested as a key factor by Thompson, who found that men who possess those qualities more commonly found in women, such as sensitivity , were similarly more likely to be religious. Reasons other than oppression that lead a higher percentage of women to respond to their environment and pursue happiness through religion are the increased levels of poverty they experience. Official figures show women are 14% more likely than men to live in households with incomes that are 60% below the national average. More frequently diagnosed mental illness and depression in women can explain their higher contribution to religion, as cults, sects as a social network and comfort for women outside the isolation of the home or of their minds. Women’s tend to be more open about sharing personal problems and are more relational than men which is encouraged in the close knit community of a sect. The intimacy of the private sphere can also replicate women’s â€Å"sphere of the home† whilst theodicies explaining their feelings and offering solutions justify their role as a woman. New Religious Movements such as cults are also generally more popular with women because of cult focus on self-discovery and fulfilment, which correlates with the female inclination towards self-criticism and self-improvement, due to their suffering higher levels of marginalisation and lack of self-confidence. Some evidence contradicts the male role as non-spiritual however, as Davie found there is an equal spiritual confidence in the existence of ghosts between genders. A key to understanding modern women’s higher participation in religion is the shifts in demographic trends. Brierly’s study found that in 1979 the proportion of male church goers were 45% but in 1989 it had dropped to 42%. The ratio of live females to live males rises steadily and correspondingly a disproportionate number of elderly women seek refuge in the church in response to loneliness or consoling philosophy nearing the end of their lives. Davie explains how women are more actively responsive to religion because males and females have differing visions of God; males associate him with power and status whereas women associate with his traits of love, comfort and forgiveness which explains their greater involvement in community religions. They are more concerned with people orientation than control. Female differences in nature also explains the particular appeal of New Age ideas revolved around well-being and stress relief. Concepts such as herbalism, yoga and meditation, homeopathy, aromatherapy and massage, horoscopes, astrology, fortune-telling are strongly associated with females, according to Glendinning and Bruce. This recent marketization of religion often promotes earthly concepts which are more linked to femininity and female empowerment than the tradition of male domination. Mother Gaia, the theory of Mother Earth as a living entity, is more appealable to women for instance. Women’s heightened spirituality can be attributed to their greater role in biological life processes. Walter and Davie see women as more emotionally exposed to the â€Å"ups and downs† of life because of childbirth, and their nurturing role as teachers, care assistants, social workers, and so on, and also the expectation that they be unpaid carers for vulnerable family members. This heightens their sensitivity and attunes the spiritual dimension of human existence, because as Davie argues, these factors give women a closer association with birth and death which are generally central concepts of religion. As females live longer than men some studies have shown that many widowed women may turn to religion for the comfort of reassuring philosophies and social networks. It is possible that some women take refuge from some of the theoretical oppressions bore by religion. Swatos talks of the fulfilment that can be had from being a second class citizenship. Feminist writers like Walby and be Beauvoir suggest that the doctrine of many of the world’s religions contain an ideology of the family which emphasises women’s traditional roles as wives and mothers in the family. Some women, however, are happy to take on this role. Barrett and Pryce, for instance, highlight how Rastafarianism assumes the woman’s position as a housewife and mother as a protection from sexual and racial abuse in the outside world. On one hand this gives ultimate power to men by denying female participation to society in the name of protection, but some more introverted Rastafarian women may enjoy this safety within the sphere of the home. A similar contradiction of female subjugation is the veil; whilst Aldridge notes the hijab in Islamic cultures as a symbol of patriarchy, degrading women to a state of invisibility and keeping them devoid of identity, some women find anonymity to be protective from the judgement and sexual degradation of men. A growing number of Western Muslims have taken to wearing the veil to in fact reinstate a female identity separate from their face; writers like Ahmed and Watson argue that the veiling of one’s face can be a way to resist the patriarchy and sexual objectification of Western culture which views women as visual objects. Faiths as a majority oppose the admission of women to leadership in religious organisations. A pun of the â€Å"stained glass ceiling† is used as a pun by sociologists to explain how women are maintained at the bottom of the career ladder to authority within the church, and barred completely from the priesthood in Roman Catholicism and Orthodox Judaism, which is seemingly discriminatory, but perhaps female role models within religious doctrines presented as meek and nurturing figures have had such an influence on the identity of a religious women that they feel more comfortable in a non-domineering role. Examples can be taken from any religion proving the sub-ordinance of women taught by most faith systems. The socialisation of women to be obedient and take on the follower role means they are further likely to be a willing follower of religion. Overall social, psychological, and biological factors interlink to form explanations for greater female participation in religion and religious organisation. The gravity of female relation to religion as an explanation, compensator, duty, and social outlet mean that their commitment is likely to persist regardless of the injustices and subjugations it bears upon the gender.

Effect of Solar Magnetic Field (SMF) on Solar Radio Flux

Effect of Solar Magnetic Field (SMF) on Solar Radio Flux Paper published in the proceedings of Conference on Recent Trends of Research in Physics (CRTRP 2012); Page no. 85-91, 2012, ISBN: 9788190436298 3.1. Introduction: The solar activity appears to be straightforwardly associated with the strong and complex solar magnetic field.The huge solar magnetic field is a result of the flow of plasma currents within the Sun, which impel charged particles to move about from one of the Sun’s poles to another. The mean magnetic field is the strength of the longitudinal component of the photospheric magnetic field averaged across nearly all the visible hemisphere of the Sun. The sun’s magnetic field has the remarkable property that it is not distributed uniformly, but concentrated in flux ropes which appear on the surface of sunspots, plages and network. Hale first found the evidence of strong magnetic field in the sunspot from the Zeeman splitting (Hale 1908). Sunspots are the seats of the strong magnetic field and the field strength of a large sunspot can be as high as 3000 Gauss. Due to the strong magnetic field inside the sunspot, the convection is inhabited and the region becomes relatively cooler and hence darker compared to its surrounding region. So sunspots can be treated as the best manifestation of the Sun’s magnetic field (Solanki 2003). Figure: 3.1.1. Solar magnetic field (Image credit- http://www.nasa.gov) The variations of sunspot number have well-established periods of about 11 years (Hathaway et al.2002). The period of magnetic activity cycle is twice as that of sunspot cycle, about 22 years on average (Hale et al. 1919). Most of the solar activity parameters vary consistently with the sunspot cycle. Among these parameter solar radio flux is one which has its own importance in Radio Astronomy as the precise information about its emission from its origin region provides the details about the temperature, constituents, density, ionization, magnetic fields and the physical nature of the various sources inside Solar structure (Kundu, 1965). Thus to diagnose the solar atmosphere and the magnetic energy release in solar corona, radio observations serve as a powerful tool. The radio flux has its origin from atmospheric layers high in the solar chromospheres and low in the solar corona, though the accurate level of origin is not yet fully known (Kane, 2003). Observations at different radio frequencies provide the information about the various depths and the physical structure on the solar atmosphere. Accurate daily radio fluxes at different frequencies are very useful for the study of solar physics of the different layers of solar atmosphere (Zieba, 2001). Many workers have performed correlation and spectral analysis of solar radio flux variations (El-Raey and Scherrer, 1973). Watari (1996) analyzed solar radio emission at several frequencies to investigate their irregularities, time variation and solar coronal activity at different heights. Kane et al. (2001), Vats et al. (1998) and Mouradian et al. (2002) used the solar radio fluxes at different frequencies to study the coronal rotation period at different heights and its differentiality as a function of the altitude. Meheta (2005) has studied the relationship of rotation period with different phases of solar cycle. It is already evident in the literature that various frequency bands in the range starting from 245 MHz to 15400 MHz originate from different layers of solar atmosphere starting from lower chromospheres to upper corona as illustrated in the Table 3.1. Thus study of radio flux at different frequencies within this range provides the information about different layers of solar atmosphere. Table 3.1. : Different radio frequencies and their origin in solar atmosphere The quiet Sun emission at different frequencies contains information about densities and temperatures in different layers of the solar atmosphere (Watari, 1996). It is one of the prime reasons of studying solar radio emission at different frequencies during the Solar Figure: 3.1.2. Monthly variation of sunspot number for the year 2009. (Image credit- http://www.greatdreams.com/solar/2009/space-weather-december-2009.htm) minimum period which provides an opportunity to the scientific community to study the physical behavior of Solar atmosphere. It also provides very useful information about the temperature and the shape of the solar corona (Kundu, 1965). Thus the study of solar radio emission during the minimum period serves as an important tool for the study of solar corona. The current minimum of cycle 23-24 has been treated as a peculiar minimum characterized by reduced polar field strength, extremely low level of solar activity and extending for longer duration (Gopalswamy et al, 2012). Various solar indices like F10.7 cm, EUV flux, solar wind etc. behaved unusually during this minimum. Even the ionosphere also showed an anomalous behavior (Eduardo et al, 2011). The boundary between the Earth’s upper atmosphere and space also moved to an extraordinary low altitude (www.sciencedaily.com/releases/2008/12/081215121601.html) during the period. This type of unusual behavior of this minimum has c reated the interest among the solar science community to make a rigorous study on this period. The microwave brightness temperature during this minimum was substantially diminished compared to the 22-23 minimum which is also consistent with the decrease in solar magnetic field strength (Gopalswamy et al, 2012). Basu (2010) found the evidence of difference of Sun’s internal structure during the current minimum from the minimum of previous cycle. During the minimum period, the 2800 MHz radio flux showed an anomalous behavior in its correlation with Sunspot number (Tapping, 2011). In the context of above peculiarities of current solar minimum, it is interesting to see the variation of correlation of solar radio flux at several frequencies with sunspot number during this period. In this chapter the preliminary results regarding the study on the relation of solar radio flux and solar magnetic field parameters have been presented. Here the frequency distributions of correlation coefficients of solar radio flux with sunspot number and solarmagnetic field have been investigated for solar minimum and maximum period. We have also make analysis of periodic variation of basal component of solar radio emissions. 3.2. Observation: Here we studied the behavior of solar radio flux for the extended solar minima of Solar cycle 23 (2009). Firstly, we calculated the correlation between the solar radio flux and Sunspot number which is the index for measuring the variability of these two solar activity parameters. We have found the correlation coefficient at eight frequencies (245, 410, 610, 1415, 2695, 4995, 8800, 15400 MHz) using data from Sagamore Hills radio Solar observatories. For the calculation of correlation coefficient, we excluded the points from dataset of those radio fluxes, which are having values greater by 40% of the average flux value of a day. It has been done for neglecting sudden variation in flux due to several transient activities. The correlation coefficients are plotted in figure. 3.2.1 3.2.2. Correlation coefficient between the sunspot and radio flux Many workers (Das and Nag, 1999, Das and Nag, 1996) have shown that the frequency distribution of correlation coefficients of the solar radio flux and Sunspot numbers follows a pattern. We have calculated the correlation coefficients for solar maximum (2001) and minimum (2009) of solar cycle and found that the frequency distribution of the correlation coefficients does not show the similar pattern as has been reported in the literature. During the maximum period the correlation coefficient is highest for 1415 MHz but in minimum it’s highest for 2695 MHz. In literature also it has been reported that the correlation coefficient attains its maximum value at Figure 3.2.1: Frequency distribution of correlation coefficients of solar radio flux and sunspot number 2695 MHz as it is very close to the 2800 MHz (Das and Nag, 1996). But during the solar maximum period the highest correlation has been found for 1415 MHz while at solar minimum period it is for 2695 MHz. Rather that this after 2695 MHz there is a decline in the correlation coefficient of higher frequencies for maximum period where as for minimum period the trend is Figure 3.2.2: Frequency distribution of correlation coefficients of solar radio flux and sunspot number not same as the 8800 MHz shows a correlation which is greater than for 4995 MHz. Rather than this the variation of correlation coefficient has also been checked for different solar minimum period. Das and Nag, 1996 has already reported the correlation coefficient of the radio flux and the sunspot number for the 1975, 1986, 1996 minima. We have compared these correlation coefficients with the obtained ones for 2009 solar minimum. From the plot it can be noted that during this period the value of the correlation coefficient is very low in comparison to the value of the previous three minima. 3.2.3. Correlation coefficient between the solar mean magnetic field and radio flux Like the radio flux and sunspot number, the correlation between the radio flux and solar mean magnetic field has also been checked for this minimum period. It has been found that the values of the correlation co-efficient are very low and the there is a pattern in the variation of the frequency distribution of the correlation coefficients. Figure 3.2.2: Frequency distribution of correlation coefficients of solar radio flux and solar mean magnetic field 3.3. Discussion: In this chapter, the relation between the solar magnetic field and the solar radio flux has been investigated. In the foregoing analysis the correlation coefficient of radio emission and sunspot number, has been found to be low with respect to the correlations of other cycles. Where as the correlation of solar mean magnetic field and radio flux is also very low. During this minima period, the frequency distribution of correlation coefficient of radio flux and sunspot number and the periodic behavior of solar radio flux is random whether it has a similar pattern for previous three minima (Das, 1998). The anomaly in correlation of radio flux with sunspot number might be due to the unusual behavior of the microwaves as it has been already reported for the correlation between 2800 MHz and sunspot number (Hudson, 2009). There was a change in activities between photospheric and chromospheric or coronal indices during the later part of cycle 23, through the extended minimum (Tapping, 2011) and the polar magnetic fields of Sun have an important role in shaping the Solar corona and heliosphere around the Solar minimum period when the polar dipole moment becomes leading component of large scale magnetic field of the Sun (Wang and Sheeley, 2002). During this minima period, Sun’s polar field was 40% less compared to the previous three minima (Wang et al, 2009). Consistently, the corona also retained some complexity during the lowest activity level (Toma et al, 2010a). During the current minimum, the Solar corona never reached at a simple dipolar configuration (De Toma et al, 2010b) rather the eclipse data showed higher order multi-polar structure (Judge 2010). Thus different magnetic configuration is supposed to give rise to a different morphology of Solar corona rather than from the previous three minima. Thus different magnetic configuration is supposed to give rise to a different morphology of Solar corona rather than from the previous three minima. The variation obtained in correlation coefficient’s pattern could also be due to this complex behavior of Solar corona and heliosphere. 3.4. Concluding remarks: The preliminary study presented in this chapter points that during the recent solar minimum, the correlation coefficient of radio emission and sunspot number has been low with respect to the correlation coefficients of previous solar minima. Rather than this the correlation of solar mean magnetic field and radio flux is also found to be very low during this minimum period. During this minima period, the frequency distribution of correlation coefficient of radio flux and sunspot number is random whether it has a similar pattern for previous three minima (Das and Nag 1998). The frequencies studied at the present work for analyzing the characteristics of Solar radio flux, provide information about the complex behavior of Solar corona and different shape of corona with respect to the previous minima during (Toma et al, 2010b). However we believe that detail investigation with more independent analysis using different parameters is required to critically analyze different Solar features especially during the current minima period to have more insight about the physical processes going on inside the Sun at different time scales.
