Spatiotemporal crime analysis in U.S. law enforcement agencies: Current practices and unmet needs

This article compares the current states of science and practice regarding spatiotemporal (space + time) crime analysis within intermediate- to large-size law enforcement agencies in the Northeastern United States. The contributions of the presented research are two-fold. First, a comprehensive literature review was completed spanning the domains of Criminology/Crime Analysis and GIScience/Cartography to establish the current state of science on spatiotemporal crime analysis. This background review then was complemented with a set of interviews with personnel from seven intermediate- to large-size law enforcement agencies in the United States in order to establish the current state of practice of spatiotemporal crime analysis. The comparison of science and practice revealed a variety of insights into the current practice of spatiotemporal crime analysis as well as identified four broad, currently unmet needs: (1) improve access to externally maintained government datasets and allow for flexible and dynamic combination of these datasets; (2) place an emphasis on user interface design in order to improve the usability of crime mapping and analysis tools, (3) integrate geographic and temporal representations and analyses methods to better unlock insight into spatiotemporal criminal activity, and (4) improve support for strategic crime analysis and, ultimately, public safety policymaking and administration. The results of the interview study ultimately were used to inform the design and development of a spatiotemporal crime mapping application called GeoVISTA CrimeViz.     

Special Collections and Archives Code (SPAC): Preserving Provenance in a Bibliographic Catalog

The recording of provenance is of particular importance in special collections cataloging, as knowledge of provenance lends authenticity and reliability to the materials held. A method of cataloging collection-level provenance in bibliographic records through a short mnemonic code, a Special Collections and Archives Code (SPAC), is described which enhances visibility of collections and retrieval in a catalog. A collection code not only collocates unique individual items that share a common characteristic, but can also constitute part of a linked data approach to visualizing integrated collections in the form of a “virtual bookplate.”

What is really causing the obesity epidemic? A review of reviews in children and adults

Obesity prevention is a public health priority and intervention strategies have focused primarily on healthy eating and physical activity in children and adults. To date, no review has systematically compiled and synthesised the scientific evidence from published review articles to determine whether there is clear consensus on the causes of obesity. A systematic review of the literature was conducted searching PubMed/Medline for narrative and systematic review articles published between January 1990 and October 2014 that examined the causes of obesity. In total, 12 of 65 articles met the inclusion criteria; 7 reviews focused on adults (1 systematic, 6 narrative) and 5 reviews on children (2 systematic, 3 narrative). The most popular cause of obesity identified in reviews of adult studies was “combined physical activity and diet” (3 of 7 studies), whereas the most popular cause specified in reviews of child studies was deemed “inconclusive” (2 of 5 studies). While a number of reviews have examined the causes of obesity, the methodology and conclusions varied widely, and few were conducted systematically. Currently, no consensus exists across published literature reviews regarding the primary cause of the obesity epidemic, and more research, particularly prospective studies using state-of-the-art measures, is warranted.     

The effect of distance learning classroom design on student perceptions

This study investigated the effects of camera angle and monitor placement in a simulated distance-learning environment. Of particular interest were the effects on perceived instructor credibility and immediacy behaviors. A videotape of a lecture on an academically relevant topic was produced using a high-angle and an eye-level camera. Participants viewed one of the presentations in either a traditional classroom design (one monitor, front center of room) or in small groups with a monitor for each group. Participants were observed as they viewed the videotape of interest, following which they completed a questionnaire and posttest. Results suggest that an eye-level camera, and multiple monitors with groups of 4–5 students positively influence instructor credibility, immediacy, and interactions. The implications of these findings and recommendations for design of a distance-learning classroom are discussed.     

Chinese pre-service biology teachers’ evolutionary knowledge,reasoning patterns,and acceptance levels

The goal of our study was to examine a large (>400), cross-sectional sample of Chinese pre-service biology teachers (PBTs) in order to document their evolution acceptance levels, evolution knowledge, and evolutionary reasoning patterns. This approach was taken in order to better understand the degree to which particular evolutionary reasoning difficulties exist independent of religious worldviews. The sample included (1) 160 PBTs tasked with completing four items from the ACORNS instrument, (2) 320 PBTs who completed the CINS and MATE instruments, and (3) 32 teachers who completed semi-structured clinical interviews using four ACORNS items. Findings from these samples revealed that Chinese PBTs’ knowledge (CINS) and acceptance (MATE) were equivalent with teachers’ scores from other countries, whereas performance on explanation tasks was lower. Scores from the CINS, MATE, and ACORNS did not reveal any significant improvements through the four-year teacher education programme. Although a large body of work has shown the important roles that religious affiliation and religiosity can play in evolutionary understanding and acceptance, our findings demonstrate that many evolutionary reasoning difficulties extend beyond religious factors, and add to a growing body of work showing that religiosity does not adequately account for PBTs’ moderate evolution acceptance.     

Citizenship and enterprise: issues from an investigation of teachers' perceptions in England and Hungary

We explore the perceptions of teachers concerning citizenship and enterprise in Hungary and England. Contextual matters are described and research methods outlined prior to a discussion of emerging issues. We argue that citizenship in both countries is understood broadly in terms of what it means to be human. The English teachers emphasized community issues and being socially active more often than those in Hungary. Hungarian teachers were less positive about state and civil society and more patriotic about their country. In both countries those in provincial towns (rather than those in capital cities) suggested a belief in the need for a greater adherence to rules. There was greater enthusiasm for citizenship education in primary rather than secondary schools in both countries. All teachers seemed wary about a form of enterprise education that relates directly to the economy and this was especially true for the Hungarian sample. Teachers in both countries, while recognizing the current emphasis on competition between and within schools, tended to characterize citizenship education as a constructive social enterprise (rather than an economic enterprise), in which young people are encouraged to explore problems and develop their initiative and capacity for action. All teachers favoured a collaborative and broad‐based pedagogical approach in which young people are allowed to explore social and political issues through dilemmas.
