Study on the impact of exposure to noise in professional snipers

Facing an increasing violence level and higher firepower in the hands of criminal organizations (especially those related to drug trafficking), the Military Police of Pernambuco has created, in 1989, the "1a Companhia Independente de Opera??es Especiais" (1st Independent Company of Special Operations), as a tactical last resort of the Police to be used on special, complex situations. The CIOE progressively makes use of Negotiation measures, of less-than-lethal maneuvers, of Precision Shots and Tactical Assaults. When all possibilities are drained, the Precision Shot will bring the crisis perpetrator down. This study had as an objective to assess the level of impact noise suffered by the elite snipers of the 1st CIOE-PE in their training. The working conditions of the snipers were evaluated through the use of a semi-structured questionnaire. Noise measuring was done on four (4) .308 IMBEL AGLC (with ammo from the same lot) rifles. Six (6) shots were fired off each gun, separated by a 30-second pause. In the end, it has been concluded that the noise level the 1st CIOE snipers are submitted to is considered to be normal by Brazilian legislation.     

The impact of newsroom changes and the rise of social media on the practice of media relations

Recent changes in American media have resulted in direct impacts on the work of PR professionals, from newsroom reductions in traditional media outlets to the rise of social media. This study examines changes in the media relations dynamic with qualitative, in-depth interviews from 12 PR professionals in a medium, eastern U.S. city. Findings include PR professionals doing less traditional media relations, mostly attributable to downsized newsrooms, and frustration with the resulting dearth of institutional knowledge, influx of young, inexperienced reporters, and shallow stories. While participants see opportunities to inject unfiltered messages in media, overall they value reporter relationships and using social media in communication with them and in their job. Although new media are seen as one more task on an already very full PR plate, participants acknowledge their importance and growing relevance. Overall, PR professionals see their and the industry's future including both traditional and new media.     

Relationship building and the use of Web sites: How Fortune 500 corporations use their Web sites to build relationships

This study examines the dialogic features of corporate Web sites in order to determine the Web site practices of the corporations for building relationships with their publics. Content analysis of 100 Fortune 500 companies’ Web sites revealed that the corporations designed their Web sites to serve important publics and foster dialogic communication. The corporate Web sites appear to promote control mutuality, trust, satisfaction, openness, and intimacy. However, the corporations need to maintain repetitive interactions with their publics to enhance trust, commitment, and exchange relationship.     

Thomas Dew and the rise of proslavery ideology at William & Mary

In 1831, Nat Turner led an insurrection in Southampton County, Virginia that left more than 60 men, women, and children dead. This slave revolt left white Virginians in fear for their lives and questioning the ‘peculiar institution’ in their midst. Proslavery ideologue and William & Mary professor, Thomas Roderick Dew, stepped in and provided the intellectual foundation that calmed their fears and made the continuation of the southern way of life possible – at least for a little while longer.     

Covictims of capital murder: statements of victims' family members and friends made at the time of execution

The death penalty is often touted as a punishment providing the only way to truly serve justice and offer closure for covictims (defined as family members or friends of murder victims'). These rationales are rarely structured around the actual words of these individuals, however. The findings in this study suggest that such rhetoric oversimplifies and often misrepresents the experiences and perspectives of covictims. Through their own words, we learn that the death penalty is not always the soothing salve for the pain and suffering of covictims we wish it to be. Rather, we find much more ambivalence and complexity in the statements of covictims. The impact of the death penalty and executions on covictims and their ability to attain healing and closure is not so clear cut. By presenting the actual words of capital murder covictims at the time of execution, this inductive, exploratory study provides a novel glimpse at the perspectives of these individuals and their perception of the death penalty process.     

Watching online videos interactively: the impact of media capabilities in Chinese Danmaku video sites

In China, the implementation of a Danmaku social media system to sustain and raise user interest in online video sites is an increasingly widespread phenomenon. Danmaku technology is used to display users’ messages in written text on the online video stream. Little is known about the effects of this form of interactive enhancement. The aim of this empirical study is to evaluate the evolving media capabilities of the Danmaku system and their effects on users’ perceptions of interactivity and their intentions to continue using Danmaku. We draw on media synchronicity theory and apply it to a stimulus-organism-response model. Using this framework, we hypothesize that the media capabilities of the Danmaku system, namely its transmission velocity, parallelism, symbol sets, rehearsability, and reprocessability, elicit increased interactivity, which influences users’ instantaneous intentions to share and to continue the use of the Danmaku system. The results showed that both users’ instantaneous intention to share and their intention to continue to use were significantly affected by the perceived interactivity. Unlike the results of previous studies, our findings showed that all five media capabilities positively affected the users’ perceptions of interactivity. The potential theoretical and practical implications of our findings are discussed.     

Disability at work: Understanding the impact of the ADA on the workplace

It has been more than 25 years since the Americans with Disabilities Act (ADA) was passed by Congress. Many supporters of the law hoped that it would improve the employment outcomes for people with a disability, yet many scholars argue that it has fallen short in achieving this goal. Such judgments of success or failure are typically offered with little regard for the complex relationship between law and social change. In this paper, I apply a socio‐legal perspective to scholarly research regarding the impact of the ADA on employment. Socio‐legal studies offer a variety of concepts and perspectives, which better capture the complexity of law's impact on social life, and the various paths through which it might have an impact on social change. From this perspective, studies tend to assume that ADA law will either impact social change directly or indirectly. I discuss the findings of both of these approaches and conclude with some directions for future research.     

Making Space at the Nations' Table: Mapping the transformative geographies of the international indigenous peoples' movement

Social movement scholarship has focused increasingly upon the roles played by symbolic resources and movement discourses in the process of social transformation. Current socio-political approaches, often characterized by an excessive focus on movement structure to the exclusion of larger cultural considerations, still struggle to address adequately the process of transmutation from idea to form, from symbolic shift to material change. Through an examination of the international indigenous peoples' movement, this article illustrates the ways that space constitutes a mediating dimension of the transformative processes through which the symbolic potential of movement discourses may be manifested. The alternative spatialities and new geographies generated, deployed and legitimized by this movement have provided critical locations for indigenous peoples to enact the creative work of mobilization. It is argued that incorporating the work of critical geographers into existing sociological and political perspectives will contribute to the better apprehension of these transformative processes as well as those associated with the particularly spatialized phenomena related to globalization, development, nationalism and geopolitics.     

Access to Higher Education for the Disabled Student: a building survey at the University of Liverpool

The problems associated with disabled students gaining access to higher education are complex and can be complicated further by difficulties encountered in the built environment of universities themselves. A survey of the built environment at the University of Liverpool was carried out using a group of occupational therapy undergraduate students. Students were able to learn about access audits and understand more fully the problems associated with access as part of their own studies. Results were recorded using a computer database, which enabled dissemination of information via the university's managed PC network and Home pages on the internet. Discussion and debate centre on the dilemma between a freely accessible environment for all students and the constraints imposed by the present day built environment and economic climate. The need for effective strategies in collaboration with disabled students is also considered.     

The impact of socioeconomic status and population size on the use of the Tatar language at home

Based on econometric methods, we found that Tatar children from families with better material conditions and those who live in bigger cities are more likely to use the Russian language at home. Although Tatar seems to be well protected, thanks to local language policies after perestroika, we found some warning signs for the reformulation of public policies for the maintenance and development of minority languages in Russia.     

Contribution analysis to analyze the effects of the health impact assessment at the local level: A case of urban revitalization

The health impact assessment (HIA) is a tool used to estimate the potential impact on health of non-health-related proposals prior to implementation. While it is increasingly used in Quebec, Canada, studies have not analyzed its medium-term impacts and potential long-term impacts. We conducted a contribution analysis using in-depth interviews with key stakeholders, as well as documents, observation and images related to HIA in order to analyze its impacts on the revitalization of road infrastructure, parks and green spaces, and residential housing. Our analysis not only reflects on the decision-making process through the adoption and implementation of HIA recommendations, but also on the link between actions implemented in the field and health outcomes.     

Relationship building and message planning: An exploration of media challenges and strategies used during school crises at the P-12 level

Schools at the P-12 level increasingly face crises related to school shootings, violence, and other tragedies. Understanding the communication challenges schools face is paramount to assisting schools with communication before, during, and after crisis events. The current study focuses on the challenges created by media interest in such crises and the strategies implemented to overcome these challenges and provide responsible information to stakeholders. Interviews conducted with 21 school crisis teams at the P-12 level revealed that sensationalism, seeking alternative routes to information, and framing were key challenges in working with the media. In light of these challenges, administrators focused on creating media plans, building relationships with the media, being accurate but guarded, and communicating reassurance and reunification. Implications are discussed for school districts nationally.     

Assessing the impact of administrative policy on use of deadly force by on- and off-duty police

Deadly force research typically does not distinguish between shootings by on-duty and off-duty police. This article uses Philadelphia police shooting data from two time periods (1970-1978 and 1987-1992) and a unique quasi-experimental design to examine the comparative effects upon on- and off-duty police shootings of an administrative policy that limited police shooting discretion but that did not address questions of police weapons carrying and access to firearms. The article draws important distinctions between when to shoot and carry administrative policies and considers their impact on deadly force by on- and off-duty police.     

Local implementation of disability policies for “high incidence” disabilities at public schools in Japan and the U.S.

This study examines educators' responses to the local implementation of national special education policy changes for children with “high-incidence,” (mild cognitive and behavioral) disabilities. Sensitized by a sociocultural, developmental perspective, we examined Japanese and U.S. national educational policies for the support of children with high incidence disabilities and their implementation in local public schools. Twenty-six Japanese and 18 U.S. elementary school educators participated in individual interviews and discussed their experiences and perceptions of special education policies and their local implementation. Educators in both countries expressed common challenges, specifically, balancing legal requirements with everyday practices, adjusting to policy shifts, and negotiating support for children within and outside of their classrooms. Yet their experiences were culturally nuanced reflecting 1) relatively flexible (Japan) or fixed (U.S.) legal requirements, 2) shifts to more specialized (Japan) or more classroom-based (U.S.) support, and 3) established practices of classroom-based support (Japan) or pull-out support (U.S.). These cultural differences are examined in historical and sociocultural contexts, and implications are discussed for educators, social work practitioners, and policy makers in both Japan and the U.S.
