Sport and Crime

The publisher granted Brunel University London a permission to archive this article in BURA.Sport and crime possess the power to stir emotion and arouse debate; most people have opinions on both. Many believe a relationship exists between the two but as Francis and Braggins contend, the relationship between sport and crime is complex. For some, sport is a bastion of physical prowess and moral virtue; abiding by the rules and playing fair is considered a vehicle to encourage the wayward to veer from potential deviance or to rehabilitate offenders. A surfeit of programs designed to use sport as a method of crime control currently exist. However, sport itself contains many paradoxes and in some cases has become a realm for criminal behavior: corruption, bribery, doping, discrimination, violence, hooliganism, and a host of other undesirable behaviors are all evidenced in the delivery and practice of sport. Thus, the Hydra-headed character of sport makes the correlate between sport and crime a sometimes controversial milieu

Experimental Testing Program in Elementary Chemistry: A Preliminary Report

An experimental testing program is described which utilizes questions that are partly computer composed, in addition to a section composed by the instructor, and a retesting option to the student. Results from a trial of the program for one term indicate that (1) course grades were improved, (2) the student withdrawal failure rate was unaffected, and (3) the employed students took greater advantage of the retest than did the unemployed students

Can climate models capture the structure of extratropical cyclones?

Composites of wind speeds, equivalent potential temperature, mean sea level pressure, vertical velocity, and relative humidity have been produced for the 100 most intense extratropical cyclones in the Northern Hemisphere winter for the 40-yr ECMWF Re-Analysis (ERA-40) and the high resolution global environment model (HiGEM). Features of conceptual models of cyclone structure—the warm conveyor belt, cold conveyor belt, and dry intrusion—have been identified in the composites from ERA-40 and compared to HiGEM. Such features can be identified in the composite fields despite the smoothing that occurs in the compositing process. The surface features and the three-dimensional structure of the cyclones in HiGEM compare very well with those from ERA-40. The warm conveyor belt is identified in the temperature and wind fields as a mass of warm air undergoing moist isentropic uplift and is very similar in ERA-40 and HiGEM. The rate of ascent is lower in HiGEM, associated with a shallower slope of the moist isentropes in the warm sector. There are also differences in the relative humidity fields in the warm conveyor belt. In ERA-40, the high values of relative humidity are strongly associated with the moist isentropic uplift, whereas in HiGEM these are not so strongly associated. The cold conveyor belt is identified as rearward flowing air that undercuts the warm conveyor belt and produces a low-level jet, and is very similar in HiGEM and ERA-40. The dry intrusion is identified in the 500-hPa vertical velocity and relative humidity. The structure of the dry intrusion compares well between HiGEM and ERA-40 but the descent is weaker in HiGEM because of weaker along-isentrope flow behind the composite cyclone. HiGEM’s ability to represent the key features of extratropical cyclone structure can give confidence in future predictions from this model

Genetic sampling for estimating density of common species.

Understanding population dynamics requires reliable estimates of population density, yet this basic information is often surprisingly difficult to obtain. With rare or difficult-to-capture species, genetic surveys from noninvasive collection of hair or scat has proved cost-efficient for estimating densities. Here, we explored whether noninvasive genetic sampling (NGS) also offers promise for sampling a relatively common species, the snowshoe hare (Lepus americanus Erxleben, 1777), in comparison with traditional live trapping. We optimized a protocol for single-session NGS sampling of hares. We compared spatial capture-recapture population estimates from live trapping to estimates derived from NGS, and assessed NGS costs. NGS provided population estimates similar to those derived from live trapping, but a higher density of sampling plots was required for NGS. The optimal NGS protocol for our study entailed deploying 160 sampling plots for 4 days and genotyping one pellet per plot. NGS laboratory costs ranged from approximately $670 to$3000 USD per field site. While live trapping does not incur laboratory costs, its field costs can be considerably higher than for NGS, especially when study sites are difficult to access. We conclude that NGS can work for common species, but that it will require field and laboratory pilot testing to develop cost-effective sampling protocols

Caught in the Middle: Chat(ting) about Black School Leaders

The purpose of this article is to “chat” about my experience using Eurocentric theories in racial and culturally centered qualitative inquiry. The challenge I face is that I believe researchers can use Eurocentric theories to conceptualize ‘appropriate’ frameworks to conduct rigorous culturally responsible and sensitive research that contributes to existing scholarly dialogue and empirical literature on culturally sensitive designs in the field of qualitative research. In this paper I use my research experience to address the question, “How can researcher(s) conduct culturally responsible and sensitive research?” I use autoethnography and writing as a method of inquiry to (re)present the multi-layers of within and in-between chats while being caught in the middle. Chat metaphorically represents introspective musings, scholarly dialoguing, analyzing, interpreting, (re)presenting and defending. I use Tillman’s (2002) culturally sensitive research frame as an analytic tool to critically analyze my research design. I argue that qualitative researchers of ethnic, racial and cultural communities can conceptualize appropriate frameworks from mainstream theories to conduct culturally responsible and sensitive research that can help transform the traditional knowledge of fields in education, educational leadership, urban education, and policy

Crop calendars for the US, USSR, and Canada in support of the early warning project

New crop calendars are produced for U.S. regions where several years of periodic growth stage observations are available on a CRD basis. Preexisting crop calendars from the LACIE are also collected as are U.S. crop calendars currently being created for the Foreign Commodities Production Forecast project. For the U.S.S.R. and Canada, no new crop calendars are created because no new data are available. Instead, LACIE crop calendars are compared against simulated normal daily temperatures and against the Robertson wheat and Williams barley phenology models run on the simulated normal temperatures. Severe inconsistencies are noted and discussed. For the U.S.S.R., spring and fall planting dates can probably be estimated accurately from satellite or meteorological data. For the starter model problem, the Feyerherm spring wheat model is recommended for spring planted small grains, and the results of an analysis are presented. For fall planted small grains, use of normal planting dates supplemented by spectral observation of an early stage is recommended. The importance of nonmeteorological factors as they pertain to meteorological factors in determining fall planting is discussed. Crop calendar data available at the Johnson Space Center for the U.S., U.S.S.R., Canada, and other countries are inventoried
