Population inequality: the case of repeat

This paper employs data from the 2000 British Crime Survey for England and Wales to discuss ways of illustrating the degree of inequality in the distribution of crime victimisation. In particular, Lorenz curves are presented for major crime categories, i.e. property, personal and vehicle crime, and their components are presented. They are fitted both nationally (i.e. to victimised and non-victimised people) and amongst victims. Crime Lorenz curves over victims illustrate repeat victimisation. Additional repeat victimisation statistics, such as concentration, the percentage of repeat crimes and the percentage of repeat victims, are also shown. Threats and assaults are the most recurring crimes whereas theft of vehicles shows low rates of repetition within a year

Assessing the Consequences of Brood Parasitism and Nest Predation On Seasonal Fecundity in Passerine Birds

Brood parasites and nest predators reduce the seasonal fecundity and, hence, the population growth rates of their victims. However, most field studies do not measure directly how parasites and predators decrease seasonal fecundity, but instead measure the impact of these organisms on individual nesting attempts. Because a female may renest after losing a nest to predation, abandoning a parasitized nest, or successfully fledging a brood, knowing how brood parasites and nest predators reduce the number of offspring fledged from individual nesting attempts is not equivalent to knowing their impact on seasonal fecundity. We address this problem by developing a mathematical model that: estimates several parameters describing the natural history of this system, including the brood-parasitism rate, nest-predation rate, and probability of nest abandonment in response to a parasitism event; and extrapolates to seasonal fecundity from these parameters and others describing the length of the breeding season, the timing of events in the nesting cycle, and the productivity of parasitized and unparasitized nests. We also show how different researchers using different observational methodologies to study exactly the same population likely would arrive at noticeably different conclusions regarding the intensity of brood parasitism, and we provide mathematical formulas for comparing among several of these measures of parasitism. Our procedures extend Mayfield's method for calculating nest-success rates from nest-history data in that we simultaneously estimate parameters describing nest predation and brood parasitism, predict seasonal fecundity from these parameters, and provide confidence intervals on all parameter estimates. The model should make the design and interpretation of logistically difficult empirical studies more efficient. It also can be specialized to species affected by nest predators but not brood parasites. We use the model to analyze prairie Warbler (Dendroica discolor) and Black-capped Vireo (Vireo atricapillus) nesting data. We estimate the model's parameters for these species and use the resulting estimates to predict seasonal fecundity. For both species, the predicted seasonal fecundity closely matches the value measured directly.Integrative Biolog

Concentration of personal and household crimes in England and Wales

Crime is disproportionally concentrated in few areas. Though long-established, there remains uncertainty about the reasons for variation in the concentration of similar crime (repeats) or different crime (multiples). Wholly neglected have been composite crimes when more than one crime types coincide as parts of a single event. The research reported here disentangles area crime concentration into repeats, multiple and composite crimes. The results are based on estimated bivariate zero-inflated Poisson regression models with covariance structure which explicitly account for crime rarity and crime concentration. The implications of the results for criminological theorizing and as a possible basis for more equitable police funding are discussed

ERTS-1 views the Great Lakes

The meteorological content of ERTS images, particularly mesoscale effects of the Great Lakes and air pollution dispersion is summarized. Summertime lake breeze frontal clouds and various winter lake-effect convection patterns and snow squalls are revealed in great detail. A clear-cut spiral vortex over southern Lake Michigan is related to a record early snow storm in the Chicago area. Marked cloud changes induced by orographic and frictional effects on Lake Michigan's lee shore snow squalls are seen. The most important finding, however, is a clear-cut example of alterations in cumulus convection by anthropogenic condensation and/or ice nuclei from northern Indiana steel mills during a snow squall situation. Jet aircraft condensation trails are also found with surprising frequency

Effective speed of sound in phononic crystals

A new formula for the effective quasistatic speed of sound $c$ in 2D and 3D periodic materials is reported. The approach uses a monodromy-matrix operator to enable direct integration in one of the coordinates and exponentially fast convergence in others. As a result, the solution for $c$ has a more closed form than previous formulas. It significantly improves the efficiency and accuracy of evaluating $c$ for high-contrast composites as demonstrated by a 2D example with extreme behavior.Comment: 4 pages, 1 figur

Probation Officers Reporting of Mental Disorders and Treatment Among Juveniles in Ramsey County

A descriptive research study focusing on the mental health services available to juveniles in the juvenile justice system who have mental health diagnoses. Ramsey county juvenile probation officers were surveyed to provide information regarding this population. Juveniles in the juvenile justice system have been identified as having a high incident of mental health disorders and are a population in great need. The goal of the study was to answer several questions related to the number of youth with mental disorders in a metropolitan juvenile justice system. The information was collected using a short survey distributed to the county\u27s 44 juvenile probation officers. The surveys were distributed through inter-office mail in all the branch offices. This descriptive study confirms the high number of juveniles with unmet mental health needs. The study identifies where care is initiated and common barriers to continuation of treatment. This study provides a foundation for future studies within population that evaluate effective practice approaches. The study also provides concrete data that may be useful in supporting funding proposals for the juvenile justice system

You Get What You Deserve : The Relationship Between Injustice and the Consequences of Social Exclusion

In this current research I sought to answer two questions; 1) Do individuals have the capacity to recognize when they are being justly or unjustly socially excluded or conversely socially included? 2) Do the consequences of just and unjust social exclusion or social inclusion vary? In efforts to address these questions, I used perceptions of burden (i.e., participant’s overall contribution to a group task) to manipulate the perceived fairness of one’s inclusionary status to see how this affects the participants’ emotional and behavioral reactions. In Study 1, participants engaged in an imaginary group interaction in which they were burdensome (performing worse than the group) or non-burdensome (performing equal to the group) on a group-task while either being included or rejected. For Study 2, participants were randomly assigned to be burdensome versus non-burdensome, in a similar fashion as Study 1, and then ostracized or included by confederate players in a computerized group word game (i.e., Atimia). Participants in both studies reported their levels of perceived justice, needs satisfaction, social pain, negative affect, and aggressive behavior temptations. Participants in Study 2 also completed a behavioral aggression measure (i.e., candy allocation task). In Study 1, perceptions of justice had no impact on the consequences of social exclusion; rejected participants felt bad regardless of the fairness of their rejection. For included participants, unjust, compared to just, inclusion induced thwarted needs, increased social pain, negative affect, and aggressive behavior temptations (consequences similar to that of social exclusion). In Study 2 almost no differences emerged within the affective state of included individuals. Based primarily on the results of Study 1, it appears that burden may play a critical role in the ostracism experience. Further research is recommended to better understand this relationship

Social Scientists\u27 Conceptualization and Implementation of Research Ethics and Integrity

The purpose of the current study is to identify core themes, values, and principles through which social scientists conceptualize and implement research ethics and integrity. Periods of rapid growth and interest in research ethics and integrity often coincide with significant scientific discoveries (e.g., mapping of the human genome) or scientific misconduct (e.g., Tuskegee studies). Even though research policies are being developed, they are done in a manner which does not maximize the opportunities to regulate ethics and integrity within social science research. The laws and programs aimed at mitigating acts of misconduct were originally intended for biomedical sciences, yet they are extended to the social sciences, which are rooted in different scientific philosophies, methodologies, and utility. I believe, from a methodological perspective, that ethical and integrity guidelines developed for biomedical sciences do not provide the optimal amount of guidance and protection for researchers and participants within the social sciences. The research question: How do social scientists conceptualize and implement research ethics and integrity? was investigated using phenomenological methodology analyzed through an emergent feminist lens. Seven (N=7) social science tenure-track faculty who conduct human subjects research participated. Data yielded 7 themes; discipline/academic culture, role of the researcher, data, IRB, resources, consequences, and research ethics/integrity. Results inform foundational research into the application of researcher ethics and integrity for social scientists and provide argumentative support for further inquiry

DNA retention after arrest: balancing privacy interests and protection

The S & Marper judgement of the European Court of Human Rights addresses the question of DNA profile retention in the absence of conviction or admission of guilt. It casts the problem as a question of balancing the principles of individual privacy and public protection. In the Court's view there is a level of public protection conferred by retention of DNA from arrestees against whom no further action is taken which would justify retention, yet relevant data do not exist to determine the level of public protection gained by such retention. A pilot study is reported here showing that a group against whom arrest is followed by no further action exhibits levels of subsequent criminality (measured by frequency, latency and most severe outcome) similar to those of people officially processed by sentence or caution. Survival and count regression analyses suggest statistical approaches to be taken using larger and better samples. A research programme is outlined which would allow evidence-based policy on DNA profile retention
