The Only Thing We Have to Fear Is Fear Itself…and Crime: The Current State of the Fear of Crime Literature and Where It Should Go Next

Researchers have explored the impact of fear of crime for well over 40 years. In that time, the fear of crime literature has undergone a remarkable evolution, with researchers examining it among varied populations, in many contexts, and from different theoretical perspectives. The purpose of the current work is to provide a brief review of the fear of crime literature, with specific focus on how the research has evolved. Particular attention is placed on how the definitions and measures of fear of crime have become more precise over time. In addition, a discussion of the theoretical perspectives and consequences of fear of crime is also included, along with directions for future research.     

明末清初松江府及其周边地区人口损失与历史人口估算

如果以松江府及其周边五州县的明初历史人口数据为计算原点,再以人口增长率3.4‰为基础,便有可能算出明清各时代自然增长下的人口数字。可是如此推算18世纪末的人口,较诸同时期准确的统计人口,竟高出达200多万之谱。要处理这庞大的人口差异,其实就是要说明这数以百万计的人口是如何消失的。我们采取的方法是针对1641年至1680年间四个天灾人祸设定级别而作出微调,从而估算明末该地区的人口损失及人口发展状况。若将有关估算结果继续上推至18世纪末,也与乾嘉时代的统计人口相当吻合。这种方法一如其他估算之道,虽非定论,但可为史无明文但处于非常重要时空的中国历史人口,提供一个新的推算方法。此外,以我们的方法计算,1640年左右松江府及周边州县的人口已达500万之谱,这与乾嘉盛世同地区的人口相比,可谓毫不逊色。     

The rescission of behaviors: Inconsistent responses in adolescent sexuality data

In longitudinal survey research, certain questions can be rescinded illogically. For instance, respondents who at Time 1 report having had sexual intercourse may at Time 2 report never having done so. This paper reports measurement techniques and analyses of these types of inconsistencies from an ongoing longitudinal adolescent sexuality project. Inconsistencies in intercourse, masturbation, and other sexual behaviors are reported and compared to rates from other studies and other less sensitive behaviors within the same study. Three conclusions are presented: (1) inconsistencies should be considered a natural part of any longitudinal survey process and should be incorporated into the response model; (2) inconsistency rates in these particular data support the contention that adolescent sexuality data of appropriate quality for analytical purposes can be obtained; and (3) inconsistency rates in fact contain substantive information concerning the processes under consideration.     

A Multifactorial Risk Prioritization Framework for Foodborne Pathogens

We develop a prioritization framework for foodborne risks that considers public health impact as well as three other factors (market impact, consumer risk acceptance and perception, and social sensitivity). Canadian case studies are presented for six pathogen‐food combinations: Campylobacter spp. in chicken; Salmonella spp. in chicken and spinach; Escherichia coli O157 in spinach and beef; and Listeria monocytogenes in ready‐to‐eat meats. Public health impact is measured by disability‐adjusted life years and the cost of illness. Market impact is quantified by the economic importance of the domestic market. Likert‐type scales are used to capture consumer perception and acceptance of risk and social sensitivity to impacts on vulnerable consumer groups and industries. Risk ranking is facilitated through the development of a knowledge database presented in the format of info cards and the use of multicriteria decision analysis (MCDA) to aggregate the four factors. Three scenarios representing different stakeholders illustrate the use of MCDA to arrive at rankings of pathogen‐food combinations that reflect different criteria weights. The framework provides a flexible instrument to support policymakers in complex risk prioritization decision making when different stakeholder groups are involved and when multiple pathogen‐food combinations are compared.     

Social unrest and the Highway Beautification Act of 1965

The recent series of very senseless shootings of both African American males and police officers are chilling visual demonstrations of the current degree of racial tension and social unrest in the United States. Stricter gun control laws are critically important but only part of the issue. Basic human and civil rights are at the heart of the issue. We must move toward a society in which individuals from varied backgrounds are valued, respected, and included. We must all accept the fact that we are all human beings and very much alike. This will require a national effort very similar to the Highway Beautification Act of 1965. We must adopt and implement policies that will specifically address multiple issues (discrimination, racism, marginalization, exclusion, implicit bias, and the lack of economic mobility) serving as drivers of our current social state. A key component should be increased investment in the educational system (starting in primary school) resulting in an increased college graduation rate and the development of curricula on race and racism and supporting cultural sensitivity and implicit bias training from kindergarten through professional schools.     

Increasing College Access and Retention Rates of Youth in Foster Care: An Analysis of the Impact of 22 State Tuition Waiver Programs

Youth in foster care face educational disparities in terms of college access, retention, and graduation. To address this, 22 states have implemented tuition waiver programs targeting current and former foster youth. A comparative analysis was conducted of all 22 programs implemented since 2014. Similarities include student eligibility based on youth’s age upon foster care entry, university admission and time in care requirements. Differences include type of expenses covered, time limits on use, program oversight, and funding availability. No differences were found based on political party control, gubernatorial power, and state population composition. Recommendations for policy and practice reform are offered.     

On weighted composite scores for early Alzheimer's trials

Recent research on finding appropriate composite endpoints for preclinical Alzheimer's disease has focused considerable effort on finding “optimized” weights in the construction of a weighted composite score. In this paper, several proposed methods are reviewed. Our results indicate no evidence that these methods will increase the power of the test statistics, and some of these weights will introduce biases to the study. Our recommendation is to focus on identifying more sensitive items from clinical practice and appropriate statistical analyses of a large Alzheimer's data set. Once a set of items has been selected, there is no evidence that adding weights will generate more sensitive composite endpoints.
