Age ranges of epiphyseal fusion in the distal tibia and fibula of contemporary males and females

The range of variation in epiphyseal fusion in North American populations has not been sufficiently established. This significant oversight can lead to exclusion of persons of interest in a forensic investigation. This study evaluates epiphyseal fusion of the distal tibia and fibula in 570 European-, African-, and Mexican-American children and young adults. Radiographs of 270 females aged 9 to 17 and 300 males aged 11 to 20 were analyzed to assess the range of variation of epiphyseal fusion at each age. Results indicate that complete fusion in females occurs as early as 12 years in the distal tibia and fibula. All females demonstrated complete fusion by 16 years with no significant differences between ancestral groups. Complete fusion in males occurs as early as 14 years in both epiphyses. All males demonstrated complete fusion by 19 years. Significant differences in the earliest age of complete fusion showed that African- and Mexican-American males demonstrate complete fusion as early as 14 years in both epiphyses while European-American males do not express complete fusion until 16 years.     

Community violence in context: risk and resilience in children and families

Although some community violence research has examined the context of community violence, including the social, economic, and structural organization of neighborhoods, more needs to be learned about family, school, and community-level factors that may promote and lessen the incidence and prevalence of community violence. In addition, further research is needed on various social, environmental, and contextual factors hypothesized to protect youth from exposure. This article (a) reviews and examines the relation between neighborhood context and risk of violence exposure, (b) reviews current literature on predictors of community violence and mental health and behavioral consequences for children and families adversely affected by community violence, (c) examines sources of resilience and community strengths that extend beyond the individual, (d) discusses the contributions and limitations of current conceptualizations of risk and resilience, and (e) highlights directions for future research. Information from this review can inform community and government efforts to lessen community violence through prevention and treatment.     

The Emergence of Science as a Political Brand

This article seeks to explain how science has emerged as political brand. While science and politics have intersected for centuries, more recent social, cultural, and political events led to increased attention to the role of science in everyday life and how science is used in policy decision-making. This led to a tipping point in 2017 when the March for Science was formed, following what many in the U.S. and countries around the world viewed as anti-science stances by political leaders. The political spectacle of the March for Science not only brought increased attention to the scientific community, but also emerged to define the brand of science in society. Drawing on research from the role of brands in consumer culture – including political marketing, brand resonance, and brand community – I describe the implications of the science brand for the scientific enterprise, and the ways in which the scientific community consider the strategic communication of their brand within the political marketplace.     

Who Said What? The Effects of Source Cues in Issue Frames

Drawing on previous research concerning the role that source cues play in political information processing, we examine whether an ideological identity match between the source of a framed message and the respondent moderates framing effects. We test our hypotheses in two experiments concerning attitudes toward a proposed rally by the Ku Klux Klan. In Experiment 1 (N = 274), we test our hypothesis in a simple issue framing experiment. We find that framing effects occur for strong identifiers only when there is a match between the ideology of the speaker and respondent. In Experiment 2 (N = 259), we examine whether matched frames resonate equally well when individuals are simultaneously exposed to competing frames. The results from this experiment provide mixed support for our hypotheses. The results from our studies suggest that identity matching is an important factor to consider in future framing research.     

Wheat from chaff: Third‐party monitoring and FEC enforcement actions

Regulatory theory suggests that providing agencies with multiple sanctioning options allows them to dispose promptly of less serious matters and thereby conserve resources to pursue serious offenders. However, agencies dependent on third‐party monitoring may have their enforcement agendas skewed toward more trivial violations. We consider these competing expectations by analyzing enforcement actions at the US Federal Election Commission (FEC) from 1999 to 2004 . The FEC – an agency heavily dependent on third‐party monitoring – expanded its enforcement options in 2000 by creating two new programs to pursue low‐level offenders, while leaving its monitoring strategy unchanged. We hypothesized that more sanctioning options would allow the FEC to allocate its resources more efficiently, and thus deal more effectively with the skew created by third‐party monitoring. We found instead that although the FEC disposed more promptly of low‐level infractions, it was no more effective at focusing on serious violations. Our results suggest that for many agencies, expanding enforcement options without addressing monitoring has limited ability to resolve enforcement problems.     

Local media tone,economic conditions,and the evaluation of US governors

Connections between media coverage, economic conditions, and performance evaluations of political leaders have seldom been explored in specific local media markets, due to the challenges of measuring media tone and content for a large number of media outlets or markets. In this paper, we develop a measure of media tone by comparing the economic evaluations of local media consumers and national media consumers within the same media market. We then use this measure to evaluate the relationship between media tone and objective economic conditions. We find that positive media tone increases the probability that individuals will approve of the governor’s performance in office, and that tone also attenuates the negative relationship between unemployment and gubernatorial approval.     

A GOODS AND SERVICES TAX (GST) AND THE SMALL BUSINESS SECTOR: SOME CANADIAN REFLECTIONS

Abstract: In recent years, several Pacific Rim nations have introduced a goods and services tax (GST), similar (in some respects) to European value-added tax (VAT). Countries with GST include New Zealand, Western Samoa and Canada. In the 1993 Australian federal elections, a major issue was whether or not to introduce GST.
New taxes are seldom popular, but particularly in Canada the introduction of GST caused extraordinary concern in the small business sector which was faced with compliance costs exceeding $1 billion. This article is a case study of the Canadian experience, with some comparisons made with some features of other systems. Findings suggest that, in Canada, the smaller businesses which are registered for GST are burdened by an unproportional share of the burden. Managerial time of entrepreneurs is being used for increased accounting and paperwork requirements.
An understanding of GST and its difficulties may assist the small business sector in Australia and elsewhere in the Pacific Rim to be better prepared for GST-type taxation. It may also assist the sector in voicing its concerns to government, such that the policy-makers responsible for taxation matters may be responsive to the needs of the small business sector.
