Analysis of 120 shift systems of the police in the Federal Republic of Germany.

120 shift rotas of the police were collected and analysed. The frequency distribution of the shift cycles, the duration of shifts, the start and end of shifts, the maximal number of consecutive night shifts, as well as the frequency of different kinds of free weekends, were determined. The shift systems are compared with recommendations for the design of shift rotas which are based on physiological, psychological and social criteria.

Traffic violation detection and deterrence: implications for automatic policing.

Current efforts directed at enforcing traffic laws are beset by a dilemma. On the one hand enforcement programmes are limited in duration and intensity, thereby producing weak halo effects on drivers' behaviour. On the other hand, public attitudes towards compliance are largely conditioned by the visibility of enforcement programmes. This paper reviews the impact of the semi-automatic monitoring systems in improving detection in traffic law programmes. The effects of the technology on drivers' behaviour are assessed and implications for the development of a fully automatic traffic policing system are teased out. Secondly, the paper attempts to put into perspective any consequences that an automatic monitoring system may have for driver behaviour. The fact that such systems do not yet exist poses problems for an ergonomics evaluation of their projected impact. However, taking into account the existence of core technology, tentative conclusions can be drawn as to the likely benefits and disadvantages of such systems.

Validation of a frequency database for four STR loci for use in casework in the Strathclyde Police Forensic Science Laboratory.

Data for four STR loci have been collected from 400 samples taken from complainers and suspects encountered in casework at the Strathclyde Police Forensic Science Laboratory (SPFSL). This paper describes statistical testing which demonstrates that its use will provide operationally robust procedures. Comparisons made with data collected from other British samples confirmed no practical differences between the different frequency distributions. This work provides further confirmation of the reliability of the so-called "product rule' in estimating the frequency of multilocus genotypes in British forensic casework.

Australian Federal Police seizures of illicit crystalline methamphetamine ('ice') 1998-2002: impurity analysis.

Nineteen crystalline methamphetamine ('ice') seizures captured by the Australian Federal Police (AFP) at the Australian border between 1998 and 2002 were analysed. Using a modified gas chromatograph-mass spectrometry (GC-MS) impurity profiling approach of these samples we have identified >30 compounds associated with methamphetamine and/or its synthetic route. Major impurities detected include 1,2-dimethyl-3-phenylaziridine 8, dimethylamphetamine 14, N-formylmethamphetamine 24, N-acetylmethamphetamine 25, 1,3-dimethyl-2-phenylnaphthalene 32, 1-benzyl-3-methylnaphthalene 33 and methamphetamine dimer 34. These data are suggestive of ephedrine/pseudoephedrine as the main precursor of the 'ice' samples seized during 1998-2002. Additionally the two naphthalenes 32 and 33 further identified that 15 items in 9 seizures were produced via the more specific ephedrine/hydriodic acid/red phosphorus method. One sample comprised 75% dimethylamphetamine and 9.7% methamphetamine, representing the first Australian seizure of imported dimethylamphetamine reported.

The Southwark Police Surgeon Study 1978-1997: alcohol.

This paper takes routine clinical data from one Forensic Medical Examiner's (FME) practice over 20 years in the London Borough of Southwark. The relationship of alcohol to gender, categories of call, and patterns of variation over time are addressed. Alcohol related calls are found to be significantly associated with males who are ill or injured, but not with victims or perpetrators of violence. There has also been significant increases in alcohol related calls over the study period. There is no evidence to suggest that was influenced by the introduction of the Police and Criminal Evidence Act (PACE).

Behavioural factors in accidents at road junctions: the use of a genetic algorithm to extract descriptive rules from police case files.

In-depth studies of behavioural factors in road accidents using conventional methods are often inconclusive and costly. To explore an alternative approach, 200 cross-flow junction road accidents were sampled from the files of Nottinghamshire Constabulary, England, coded for computer analysis using a specially devised 'Traffic Related Action Analysis Language', and then examined using a genetic algorithm (or 'rule-finder' program). For comparison, the same analyses were carried out on 100 descriptions of safe turns, and 100 of hypothetical accident descriptions provided by experienced drivers. A number of findings emerged, distinguishing between accidents turning onto and off major roads; those of younger and older drivers; those that resulted in injury or in damage only; and so on. The study suggests that multiple case-studies based on police case files could be very promising, provided homogeneous samples of accidents are used. Genetic algorithms could play a useful role in preliminary assessment, but an 'information bottleneck' remains to be overcome in capturing enough detail from each case for analysis.

Canine dirofilariasis in the region of Conceição Lagoon, Florianópolis, and in the Military Police kennel, São José, State of Santa Catarina, Brazil.

Eighty dogs from a locality west of the Conceição Lagoon, in the Santa Catarina Island, Florianópolis Municipality, State of Santa Catarina, Brazil, were examined for dirofilariasis by thick smear and by modified Knott's method. Twelve of them (15%) were positive, five only by Knott's, two only by thick smear and five by both methods. Positive dogs were observed in several parts of the locality, indicating that the parasite is widespread. Prevalence was significantly higher in older animals. Size, sex, hair length, place of sleeping and hour of blood collection did not significantly influence the results. Forty dogs of the Military Police kennel, at São José Municipality, Santa Catarina State, were all negative. Studies on the transmission and control of dirofilariasis in the region should be developed.

Asthma management in police study.

Asthma is a common condition and, therefore, may be seen by the clinical forensic physician and police in widely different circumstances ranging from the autopsy room to roadside breath alcohol testing. This paper concentrates on the assessment and treatment of asthmatics detained in custody and does not refer to the Road Traffic Act provisions. A careful history and objective recording of simple severity markers and peak expiratory flow rate should identify patients who may require hospitalization or urgent treatment. Asthma mortality may be reduced by better understanding of the disease and its treatment and by greater use of prophylactic rather than reliance on relief therapy for bronchospasm.

Self-injurious behaviour in police custody.

A Royal Commission into Aboriginal Deaths in Custody in Australia, reported in April 1991, focused attention on the problem of self-injurious behaviour among incarcerated individuals. This paper examines the specific issue of the police custodial setting. A review of the relevant literature has been undertaken to identify risk factors and determine profiles of persons at risk. Preventive approaches are examined and formats for screening questionnaires are advanced.

Setting an uncorrected visual acuity standard for police officer applicants.

Government agencies have used uncorrected visual acuity (UVA) standards for many years for police officer applicants. With the passage of the Americans With Disabilities Act of 1990, public employers have concern about the validity of these standards. This report shows how data can be used to set a reasonable standard. The report includes a description of a survey of incumbents, acuity testing of a sample of incumbents, collection of essential task information, and experimentation based on the essential tasks. A series of focus group meetings resulted in agreement that 2 essential tasks officers must be able to perform when visually incapacitated are identifying a weapon in a typical room and finding spectacles that have been dislodged. The experimentation showed that a noticeable performance decrement begins to appear at 20/125 level of acuity. As a result of the research, the City of Columbus, Ohio, changed the UVA standard from 20/40 to 20/125.

Mutual policing and repression of competition in the evolution of cooperative groups.

Evolutionary theory has not explained how competition among lower level units is suppressed in the formation of higher-level evolutionary units. For example, the key problem of early evolution is small, individual replicators formed cooperative groups of sufficient complexity to allow accurate copying of the genetic material. The puzzle is why parasites did not subvert the formation of cells by obtaining benefits from the group without contributing to shared traits that enhance reproduction. These parasites would outcompete other replicators within the cell, disrupting reproductive fairness among subunits and destroying the functional coherence of the group. A similar problem arose at a later evolutionary stage with the orderly mendelian segregation of subunits (chromosomes) within cells, and reproductive fairness continued to be a problem in the evolution of insect and human societies. Here I present a simple model to show how reproductive fairness evolves among subunits to create functional coherence and higher-level units. Self-restraint, which evolves according to the kin-selection coefficient of relatedness, is not sufficient: mutual policing and enforcement of reproductive fairness are also required for the evolution of increasing social complexity.

Parasitic Cape honeybee workers, Apis mellifera capensis, evade policing.

Relocation of the Cape honeybee, Apis mellifera capensis, by bee-keepers from southern to northern South Africa in 1990 has caused widespread death of managed African honeybee, A. m. scutellata, colonies. Apis mellifera capensis worker bees are able to lay diploid, female eggs without mating by means of automictic thelytoky (meiosis followed by fusion of two meiotic products to restore egg diploidy), whereas workers of other honeybee subspecies are able to lay only haploid, male eggs. The A. m. capensis workers, which are parasitizing and killing A. m. scutellata colonies in northern South Africa, are the asexual offspring of a single, original worker in which the small amount of genetic variation observed is due to crossing over during meiosis (P. Kryger, personal communication). Here we elucidate two principal mechanisms underlying this parasitism. Parasitic A. m. capensis workers activate their ovaries in host colonies that have a queen present (queenright colonies), and they lay eggs that evade being killed by other workers (worker policing)-the normal fate of worker-laid eggs in colonies with a queen. This unique parasitism by workers is an instance in which a society is unable to control the selfish actions of its members.

Egg viability and worker policing in honey bees.

In many species of social Hymenoptera, unmated workers can lay eggs that will produce males by parthenogenesis. Nevertheless, in queenright honey bee colonies (Apis mellifera), worker reproduction is low. One possible mechanism for this difference is worker policing, the removal of worker-laid eggs by other workers. This behavior can evolve in species in which queens are multiply mated, where workers are more closely related to the sons of their mother than those of their sisters. Another possible mechanism of the low level of worker reproduction is worker-laid eggs being less viable than queen-laid eggs. We show that this difference in quality is the case for honey bees.

From conflict to collaboration: psychiatry and the hospital police.

Social control is one of the major tasks of the profession of psychiatry (Astrachan, Levinson, and Adler 1976; Adler, Astrachan, and Levinson 1981). The reduction and control of deviant behavior in the community, in the hospital, and on the psychiatric ward are essential, if underappreciated, responsibilities which psychiatrists must negotiate every day. In large urban general hospitals, an increasingly common site for psychiatric programs, deviant behavior derives both from the psychopathology of the patients and from the intrusion of criminal influences from the community. Many urban hospitals have an institutional police force that, like the psychiatry service, is charged with responsibility for managing deviant behavior, albeit through law enforcement methods rather than clinical ones. In recent years law enforcement officers and psychiatrists have increasingly become involved with each other in areas where their social control responsibilities overlap. This increased involvement has often been accompanied by tension, distrust, and, at times, overt antagonism between the two groups. This paper will describe and analyze fundamental sources of this tension and outline one approach to its reduction.

Workload, stress, and strain among police officers.

Data relevant to stress and strain were analyzed separately for police officers with high and low workloads. Although these groups of officers were not found to differ in demographic characteristics or on overall levels of stress and strain, the sources of stress and strain were remarkably different. For the low workload officer, the sources of stress and strain appear to be difficulties in interpersonal relations with peers, community, and especially with supervisors. These difficulties appear to be mediated by effects on self-evaluation. The sources of stress and strain among high workload officers appear to be stress-producing events in their lives in general, as well as in performing the job of patrol officer and in dealing with crime and related matters. The differences between high and low workload officers can be explained by social comparison theory, by identity theory, or by Selye's stress theory.

Policing the social boundaries of the American Medical Association, 1847-70.

In May 1870 the American Medical Association (AMA) voted to deny the admission of black delegates and their white colleagues to the national meeting in Washington, D.C. Historians of race and medicine have customarily viewed this decision as marking a crucial milestone in the formation of the nexus between racism and the development of the American medical profession in the era after the Civil War (1861-64). This study recasts this narrative by locating the 1870 decision in relation to the antebellum practices of the association and their social consequences for American medicine. It argues that the viability of the AMA as the national voice of the profession was critically dependent on rejecting racial equality. Indeed, at a moment when the question of the abolition of slavery polarized the nation, the AMA was founded in 1847 to create a voluntary professional organization, national in scope, dedicated to raising the standards of medical training and practice. To this end, the AMA elected presidents and selected host cities for annual meetings in the North, South, and West. Seven out of the fourteen meetings and six out of fourteen presidents were from slave and/or border states. These institutional practices together with the representation of blacks as different and enjoying an appropriate status as slaves grounded the national identity of the profession in black subordination. Similarly, the gendered discourses about healing and practices of female exclusion privileged medical authority as male by drawing on and reinforcing patriarchy. In the wake of the war, leaders hoped to restore the national character of the organization by resuming antebellum practices. In response to the new possibilities for blacks in medicine--as represented by the biracial National Medical Society--the AMA took steps to vigorously police the racial boundaries of the national profession. As this study will show, the 1870 decision reflected the logic of the racial politics at the heart of the association's antebellum past and would loom large in its future.

Sanitary policing and the local state, 1873-1874: a statistical study of English and Welsh towns.

This article examines local sanitary policing in extra-metropolitan English and Welsh towns and cities in the period 1873-4. It combines two parliamentary returns, one focusing on the appointments by towns of sanitary officers (inspectors of nuisances and medical officers), the other listing the number of nuisance cases and modes of resolutions. The article uses these databases to examine the identification of nuisances in terms of region, town type, mode of government, population, and salary of inspector. It considers also the effects of tenure and job security on nuisances identification, the effects of town wealth, and differences in the resolution of nuisance allegations by town type and region. The article shows a remarkable and perhaps unexpected sanitary activism, but also a considerable variability by region, town size, and town type.
