Radiodense bullet wipe around osseous entrance gunshot wounds

“Bullet wipe” is the material deposited by a bullet on any surface with which it comes into contact after it is fired and may contain debris from the gun barrel, including particles of primer and metal fragments from previously fired bullets. X‐ray analysis is a non‐destructive method by which traces of metallic elements can be visually detected. The analysis of osseous defects for radiodense bullet wipe (RBW) assists in determining the presence or absence of perforating gunshot wounds, especially in fragmented, skeletonized remains. The aim of our current study was to determine the frequency of RBW around entrance firearms injuries that perforated bone. We prospectively analyzed entrance gunshot wounds for RBW over a three‐year period using digital X‐ray analysis (n = 59). We retrospectively reviewed the corresponding autopsy reports to determine the frequency of RBW by biologic sex, reported ancestry, age‐at‐death, location of wound, manner of death, range of fire, bullet caliber, and presence of bullet jacket. Data were analyzed by Fisher's exact test or Chi‐square test with significance levels accepted at p < 0.05. RBW was present in 66% (n = 39) of examined cases. Decedent characteristics did not significantly alter RBW distribution, including biologic sex (p = 0.75), reported ancestry (p = 0.49), and age‐at‐death (p = 0.43). Additionally, the location of the osseous entrance gunshot wound, manner of death, range of fire, and cartridge caliber did not affect RBW detection. All cases involving non‐jacketed rounds (n = 5) showed RBW (p = 0.30). To our knowledge, this study is the first to report the frequency of RBW detection from osseous entrance gunshot wounds.     

Towards a theory of bicameralism: the neglected contributions of the calculus of consent

In The Calculus of Consent (1962: 235) Buchanan and Tullock assert: (1)?ceteris paribus, while a coalition controlling less than a majority of voters may control in either chamber, the greater the difference in the bases of representation in the two houses, the less likely is any given coalition of voters to control a majority of the seats in both chambers; (2)?the potential of cross-chamber logrolls (on issues of unequal intensity) increases the likelihood that a minority may effectively control policy making. We link these ideas to social theory approaches to bicameralism and for the empirical study of legislatures.     

Why representatives are ideologists though voters are not

Though few voters appear to hold consistent ideological views, the roll call votes of congressmen and senators can be well predicted by ideological terms. An explanation for this puzzle is that ideology allows candidates to succinctly explain their views. Because it is difficult to explain detailed positions to voters, a candidate who presents his position in ideological terms may be able to defeat a candidate who supports a set of issue positions that would, in toto, be preferred by a majority of well-informed voters were the voters aware of all the views of that candidate. This effect can be a powerful one. Moreover, ideology may be a source of electoral stability, and a means of providing regularity and structure to elite political debate.Amihai Glazer acknowledges support from the Graduate School of Business at Stanford University.

Privatisation and regulation in an Asian transitional economy: the case of Mongolia

Mongolia's transition to a market economy has entailed rapid and extensive privatisation accompanied by, inter alia, stabilisation, liberalisation and de‐regulation. The primary objective of this strategy was to cement the new political and economic order. Little weight was given to the problems created by the privatisation programme and only limited consideration given to questions of regulation in the economic, social and environmental spheres. However, the failure of the economy to translate economic growth into poverty reduction and the acceleration of the privatisation programme, which includes the progressive transfer of land, and proposals to privatise health, educational and cultural assets, have made regulation a more pressing issue. New, powerful social classes and interest groups have emerged, which have contributed to regulatory failure and capture and have undermined public policy. We identify a range of issues relating to privatisation and regulation and discuss the degree to which they are being addressed by the post‐1990 political class. Although there exist a number of regulatory agencies, there is a lack of political commitment, and only piecemeal implementation and enforcement. The scarcity of experienced and technically competent staff capable of establishing and operating effective regulatory agencies and ensuring compliance is also a major problem.

A Theoretical and Analytical Synthesis of Autopoiesis and Sociolinguistics for the Study of Organisational Communication

The purpose of this paper is threefold. First, we propose a systemic view of communication based in autopoiesis, the theory of living systems formulated by Maturana & Varela (1980, 1987). Second, we show the links between the underpinning assumptions of autopoiesis and the sociolinguistic approaches of Halliday (1978), Fairclough (1989, 1992, 1995) and Lemke (1995, 1994). Third, we propose a theoretical and analytical synthesis of autopoiesis and sociolinguistics for the study of organisational communication. In proposing a systemic theory for organisational communication, we argue that traditional approaches to communication, information, and the role of language in human organisations have, to date, been placed in teleological constraints because of an inverted focus on organisational purpose-the generally perceived role of an organisation within society-that obscure, rather than clarify, the role of language within human organisations. We argue that human social systems are, according to the criteria defined by Maturana and Varela, third-order, non-organismic living systems constituted in language. We further propose that sociolinguistics provides an appropriate analytical tool which is both compatible and penetrating in synthesis with the systemic framework provided by an autopoietic understanding of social organisation.     

The Impact of Web 2.0 on the Doctor-Patient Relationship

Web 2.0 innovations may enhance informed patient decision-making, but also raise ethical concerns about inaccurate or misleading information, damage to the doctor-patient relationship, privacy and confidentiality, and health disparities. To increase the benefits and decrease the risks of these innovations, we recommend steps to help patients assess the quality of health information on the Internet; promote constructive doctor-patient communication about new information technologies; and set standards for privacy and data security in patient-controlled health records and for point-of-service advertising.
