How concentrated is crime at places? A systematic review from 1970 to 2015

Abstract: Despite the increasing awareness and interests about the importance of crime concentration at places, scholars have not comprehensively synthesized the body of evidence related to this thesis We conduct a systematic review and meta-analysis of the evidence that crime is concentrated among places We identified 44 studies that empirically examined crime concentration at place and provided quantitative information sufficient for analysis We organized data using visual binning and fitted logarithmic curves to the median values of the bins We examine concentration in two conditions: when all places are studied (prevalence), and when only places with at least one crime are studied (frequency) We find that crime is concentrated at a relatively few places in both conditions We also compared concentration for calls for services to reported crime incidents Calls for services appear more concentrated than crime at places Because there are several ways place is defined, we compared different units of analysis Crime is more concentrated at addresses than other units, including street segments We compared crime concentration over time and found less concentration in 2000s compared to 1980s and 1990s We also compared crime concentration between US and non-US countries and found more concentration in US Finally, violent crime is more concentrated than property crime Though we systematically reviewed a comprehensive list of studies, summarizing this literature is problematic Not only should more systematic reviews be conducted as more research becomes available, but future inquiries should examine other ways of summarizing these studies that could challenge our findings

A direct manipulation interface for boolean information retrieval via natural language query

Abstract: This paper describes the design of a direct manipulation user interface for Boolean information retrieval. Intended to overcome the difficulties of manipulating explicit Boolean queries as well as the “black box” drawbacks of so-called natural language query systems, the interface presents a two-dimensional graphical representation of a user's natural language query which not only exposes heuristic query transformations performed by the system, but also supports query reformulation by the user via direct manipulation of the representation. The paper illustrates the operation of the interface as implemented in the AI-STARS full-text information retrieval system.

The impact of ethgender on self-esteem among adolescents

Abstract: This study examined the impact of ethgender, the combination of race and gender, on global and public domain aspects of adolescent self-esteem. Using the Rosenberg Self-Esteem Scale and a 3-item index, differences were observed among 10 ethgenders. Black and Hispanic males had the highest levels of global self-esteem, and Asian and Native American Females had the lowest. On public domain components white and black males had the highest scores, and Asian and Native American females had the lowest. Females (except blacks) had lower levels of both global and public domain self-esteem than did males.

Requirements engineering: In search of the dependent variables

Abstract: When software development teams modify their requirements engineering process as an independent variable, they often examine the implications of these process changes by assessing the quality of the products of the requirements engineering process, e.g., a software requirements specification (SRS). Using the quality of the SRS as the dependent variable is flawed. As an alternative, this paper presents a framework of dependent variables that serves as a full range for requirements engineering quality assessment. In this framework, the quality of the SRS itself is just the first level. Other higher, and more significant levels, include whether the project was successful and whether the resulting product was successful. And still higher levels include whether or not the company was successful and whether there was a positive or negative impact on society as a whole.
