The Effects of Displayed Violence and Game Speed in First-Person Shooters on Physiological Arousal and Aggressive Behavior

Many studies have been conducted to examine the effects of displayed violence in digital games on outcomes like aggressive behavior and physiological arousal. However, they often lack a proper manipulation of the relevant factors and control of confounding variables. In this study, the displayed violence and game speed of a recent first-person shooter game were varied systematically using the technique of modding, so that effects could be explained properly by the respective manipulations. Aggressive behavior was measured with the standardized version of the Competitive Reaction Time Task or CRTT (Ferguson et al., 2008}. Physiological arousal was operationalized with four measurements: galvanic skin response (GSR), heart rate (HR), body movement, force on mouse and keyboard. A total of N = 87 participants played in one of four game conditions (low- vs. high-violence, normal- vs. high speed) while physiological measurements were taken with finger clips, force sensors on input devices (mouse and keyboard), and a Nintendo Wii balance board on the chair they sat on. After play, their aggressive behavior was measured with the CRTT. The results of the study do not support the hypothesis that playing digital games increases aggressive behavior. There were no significant differences in GSR and HR, but with a higher game speed, participants showed less overall body movement, most likely to meet the game’s higher demands on cognitive and motor capacities. Also, higher game speed and displayed violence caused an increase in applied force on mouse and keyboard. Previous experience with digital games did not moderate any of these findings. Moreover, it provides further evidence that the CRTT should only be used in a standardized way as a measurement for aggression, if at all. Using all 7 different published (though not validated) ways to calculate levels of aggression from the raw data, “evidence” was found that playing a violent digital game increases, decreases, or does not change aggression at all. Thus, the present study does extend previous research. Firstly, it shows the methodological advantages of modding in digital game research to accomplish the principles of psychological (laboratory) experiments by manipulating relevant variables and controlling all others. It also demonstrates the test-theoretical problems of the highly diverse use of the CRTT. It provides evidence that for a meaningful interpretation of effects of displayed violence in digital games, there are other game characteristics that should be controlled for since they might have an effect on relevant outcome variables. Further research needs to identify more of those game features, and it should also improve the understanding of the different measures for physiological arousal and their interrelatedness

Auditing Economic Policy in the Light of Obligations on Economic and Social Rights

One of the things we have learned so far is that the realization of human rights, especially economic and social rights, requires resources as well as laws. The availability and use of resources is strongly influenced by the type of economic policies that States Parties implement. This paper considers how concerned citizens might audit economic policies from a human rights perspective, with a particular focus on economic and social rights. It draws on an ongoing project, directed by Radhika Balakrishnan, advised by Diane Elson, and funded by the Ford Foundation, on economic policy and economic and social rights in Mexico and the USA. The project brings together human rights experts and activists who are focussing on economic and social rights, and economists who are critical of the neo-liberal economic policies being pursued by so many governments and international economic policy institutions, such as the IMF and World Bank. (Amartya Sen has called these critical economists ?non-conformist economists?, because they do not conform to the currently dominant forms of economic analysis and policy prescription). These economists share the concerns of the human rights community about poverty, deprivation and inequality; and draw on a range of other approaches to economic policy, including Keynesian, human development and feminist economics approaches. The project aims to audit key economic polices in the two countries in the light of human rights obligations, and the analysis produced by ?non-conformist? economists

Red Giants in the Halo of the S0 Galaxy NGC 3115: A Distance and a Bimodal Metallicity Distribution

Using the Hubble Space Telescope, we resolve the red giant branch in the halo of the S0 galaxy NGC 3115. We measure magnitudes and $(V-I)$ colours for stars down to 1.5 magnitudes below the tip of the red giant branch. From the brightest stars we estimate a distance modulus $(m-M)_0=30.21 \pm 0.30$, corresponding to a distance of $11.0 \pm 1.5$ Mpc. This is in excellent agreement with the value $(m-M)_0=30.17 \pm 0.13$ determined from the planetary nebula luminosity function. Our results rule out the shorter distance modulus $(m-M)_0=29.65$ determined from surface brightness fluctuations. A histogram of $(V-I)$ colours shows a clear bimodality, indicating the presence of two distinct halo populations of roughly equal size. One has [Fe/H]$\sim -0.7$ and one has [Fe/H]$\sim -1.3$. This is the most distant galaxy in which a Population II halo has been resolved, and it is the first time a colour bimodality has been observed among the halo stars of any early-type galaxy.Comment: 15 pages, 4 figures.

Assessing and working to overcome perceived barriers to women’s participation in basketball in Lincolnshire

Basketball is sport where the prevalence of patriarchal power relations gives men more opportunities to participate and to monopolise positions of power(Hargreaves, 1992: Sporting Females: Critical Issues in the History and Sociology of Women’s Sports. London: Routledge.). In the UK, women’s participation in basketball in 2008 was only one third of the rate seen among men (Sport England: Active People Survey, 2008). This suggests a gender divide in accessibility to basketball. Moreover, there is a lack of sociological understanding of the needs and perceived barriers among women who wish to participate. Inclusive policies are needed to reduce ethnic, cultural, religious, political and economic barriers among women. This will help to meet the legacy aims of London 2012 (The London Organising Committee of the Olympic Games and Paralympic Games Ltd, 2008: Diversity and Inclusion Strategy. LOCOG: London.). The principal aim of the present study is to assess women’s perceptions of the sociological barriers to participation in basketball, with a view to developing further competitive and recreational opportunities in a city in the East of England. In the study location there are few opportunities for community-dwelling women to participate in basketball. The only club offering competitive basketball is 33 miles away, creating large restrictions to those with small income and travel restrictions. The project will seek to i. assess perceived barriers to participation current female basketball participants in the area, and then ii. to set up the first all female Basketball team in the study location by offering a free taster session, followed by a series of training sessions. Quantitative methods, including semi-structured interviews, will be conducted to assess their pre-conceptions about accessibility, opportunities and negative experiences within basketball. These data will inform subsequent actions and deliver basketball sessions. Critical success factors include attendance rates and participant satisfaction. Researchers will work alongside the coaches delivering the sessions, the participants, the Lincolnshire Basketball Association and the Basketball Development Officer to create better access and local opportunities

Gender Equality as an Entitlement: An Assessement of the UN Woemn\u27s Report on Gender Equality and Sustainable Development 2014

Concerns about gender equality and women’s empowerment are re-emerging as part of the post-2015 global development agenda,and addressing them is one of the Sustainable Development Goals(SDGs).Every five years, the United Nations Division for the Advancement of Women(known since 2010 as UN Women),publishes a ‘World Survey onthe Role of Women in Development’. These Surveys are presented to the Second Committee of the General Assembly and focus on specific development themes.The 2014Survey focuses on gender equality and sustainable development and was commissionedto inform the SDG process.Itmakes a case for linking gender equality andsustainable development on the grounds that ‘causes and underlying drivers of unsustainability and of gender inequality are deeply interlocked’(p.11). Furthermore, itnotes that: ‘women’s knowledge, agency and collective action are central to finding, demonstrating and building more economically, socially and environmentally sustainable pathways to manage locallandscapes; adapt to climate change; produce and access food; and secure sustainable water, sanitation and water services’(p.13)

Field Persistence of \u3ci\u3eSteinernema Carpocapsa\u3c/i\u3e Weiser (Ny001), \u3ci\u3eSteinernema Feltiae\u3c/i\u3e Filipjev (Valko) and \u3ci\u3eHeterorhabditis Bacteriophora\u3c/i\u3e Poinar (Oswego) in Alfalfa Fields

The long term field persistence of Steinernema carpocapsae Weiser, strain NY001, S. feltiae Filipjev, strain Valko and Heterorhabditis bacteriophora Poinar, strain Oswego was investigated in an alfalfa field infested by the alfalfa snout beetle, Otiorhynchus ligustici L. Nematodes were applied in single-species, two-species and three-species combinations at a total of 2.5 × 109 infective juveniles per hectare. Soil samples were taken approximately every two weeks from mid/late May to late October in 2004 and 2005. Two soil samplings were conducted in 2006 at the end of May and in early July. All nematodes persisted in the field at the time of the last sampling in July 2006, over two years after application suggesting long term persistence of these nematodes and the potential to coexist in combinations. Steinernema feltiae Valko was not detected in the three-species combination after June 8, 2005, approximately one year after nematode application suggesting that S. feltiae Valko cannot compete effectively when a specialized ambusher nematode (S. carpocapsae NY001) and a specialized cruiser nematode (H. bacteriophora Oswego) are present simultaneously. In 2006, two years after nematode application, a marked movement of nematodes into experimental plots where they were not applied was observed. S. carpocapsae NY001 was found in the highest number of plots where it wasn’t applied. Given the ambusher behavior of S. carpocapsae NY001, it is suspected that its movement occurred via infected, but still live adult alfalfa snout beetles
