Policing styles: Notes on an empirical synthesis of Wilson and Muir

The works of James Q. Wilson and William Ker Muir stand as classics in the recent but voluminous literature on police. The concept of style is central to both analyses. Wilson focuses on departmental approaches to law enforcement, while Muir examines individual police perspectives. Both emphasize, however, that style is a critical component of law enforcement policy.Scrutiny of the typologies constructed by Wilson and Muir reveals patterns of compatibility and conflict. Assuming that simple congruity of approach carries critical consequences for policing, the authors initiated an empirical extension and synthesis of the works of Wilson and Muir.Surveying police in eighteen departments across the country (72.2 percent of the 900 potential respondents returned completed questionnaires, leaving a sample of 650), the authors hypothesized that simple congruity of policing style along three lines of comparison (individual officer and supervisor, individual officer and squad, and individual officer and department) would be associated with attitudinal perspectives long thought to be part and parcel of the “police personality.” Additional hypotheses were advanced about the relationship between congruity of style and other officer perceptions—particularly job satisfaction and assessments of supervisor support, departmental discipline, and management.The results: indicate that style congruity is critical at the lowest levelsof the organization, reinforce the importance of the first-line supervisor in policing, extend and refine the concept of style as advanced by Wilson and Muir, and demonstrate the utility of replication and synthesis in social science.     

Recent trends in the Social Security Disability Insurance Program

Earlier analysis documented the rapid growth of the Disability Insurance (DI) program from 1966 to 1975; this article discusses trends since 1975. Over the decade of the 1970's, the population insured for disability increased by 34 percent, and women as a proportion of the insured population rose from 32.4 percent in 1970 to 39.1 percent in 1980, reflecting the increase in female labor-force participation. Of disabled workers receiving benefits, the proportion that were women rose from 28.4 percent in 1970 to 32.4 percent in 1979. Although inflation caused total benefit costs to rise over the entire period, the number of DI beneficiaries began to decline in 1978. Disabled-worker awards reached a peak in 1975 and fell subsequently so that the 1969 and 1981 figures are approximately equal. Relative to 1970, the fraction of awards going to women increased, the share for persons aged 50-54 rose, and the proportion received by those aged 60-64 declined. Decreased in total awards, and hence recipients, stemmed primarily from higher rates of denial at both the initial application and the reconsideration stages. Higher denials were countered by substantial rises in the number of hearings and reversals by administrative law judges (ALJ's). in 1980, only 65 percent of all awards came from initial applications, while over a fourth resulted from ALJ reversals. In future years, recent legislative changes may be expected to curtail program expansion further.     

Ambiguity and conflict in sentencing research: Partial resolution through crime-specific analysis

Prior research on factors influencing sentence severity has produced ambiguous findings. To resolve some of this ambiguity, a crime-specific approach to data analysis is proposed and tested. The research sample consists of 468 convictions resulting from 619 indictments for the crimes of murder, rape, aggravated assault, and robbery. Independent variables examined include seven offender and case-processing characteristics. The dependent variable, sentence severity, is measured first as a dichotomous variable (probation or prison) and then as an interval variable (prison-sentence length). After determining that crime type explains a significant proportion of the total variance in sentence severity, the dependent variables are then regressed on the variable list. Four regressions are performed for each dependent variable; the first analysis uses all cases in the sample, while the remaining analyses focus separately on the crimes of murder, assault, and robbery. The research indicates that the aggregate and crime-specific analyses produce substantively different results, both in terms of the factors found to influence sentence severity and the total amount of variance explained. Findings demonstrate the utility of crime-specific analysis.     

The development of antiamerican attitudes among Korean university students: An exploratory survey

South Korean student anti-Americanism has attracted a great deal of attention in recent years. Previous studies have emphasized the political and historical causes and implications of anti Americanism. The present study approaches the problem from a social psychological and developmental perspective. South Korean students enter college without strong feelings or well-informed opinions about America, either negative or positive. They quickly acquire mostly negative feelings and opinions. They do not necessarily become anti-American, but they do become substantially less favorably inclined toward America—either more anti-American, or less pro-American, than they were before becoming college students. An explanation in terms of their experiences while preparing to become students is offered.     

Perceived coercion and need for hospitalization related to psychiatric admission

Psychiatric hospitalization constitutes a moment of major stress to the point that occurrences of posttraumatic stress disorders have been described. Feelings of coercion are usual, whatever the legal status of admission. Patients may also consider afterwards that they needed hospitalization even if they refused it initially. A cross-sectional survey has been conducted among the inpatients of a Swiss psychiatric hospital to assess their subjective view of admission with emphasis on legal status, perceived coercion and need for hospitalization. Eighty-seven questionnaires were completed and analyzed. Results indicated that 74% of patients felt that they had been under pressure to be hospitalized, whether or not they were involuntarily admitted. Seventy percent felt their admission was necessary. More involuntary patients reported a subjective lack of improvement. Clinicians could decrease feelings of coercion of their patients while discussing need for hospitalization, legal status and subjective feeling of coercion as different dimensions. An argument is presented to favor positive pressure from social environment over legal involuntary commitment in many hospitalizations.     

Validation of a male-specific, 12-locus fluorescent short tandem repeat (STR) multiplex

Y chromosome-specific short tandem repeat (Y-STR) analysis has become another widely accepted tool for human identification. The PowerPlex Y System is a fluorescent multiplex that includes the 12 loci: DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439. This panel of markers incorporates the 9-locus European minimal haplotype (EMH) loci recommended by the International Y-STR User Group and the 11-locus set recommended by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Described here are inter-laboratory results from 17 developmental validation studies of the PowerPlex Y System and include the following results: (a) samples distributed between laboratories and commercial standards produced expected and reproducible haplotypes; (b) use of common amplification and detection instruments were successfully demonstrated; (c) full profiles were obtained with standard 30 and 32 cycle amplification protocols and cycle number (24-28 cycles) could be modified to match different substrates (such as direct amplification of FTA paper); (d) complete profiles were observed with reaction volumes from 6.25 to 50 microL; (e) minimal impact was observed with variation of enzyme concentration; (f) full haplotypes were observed with 0.5-2x primer concentrations; however, relative yield between loci varied with concentration; (g) reduction of magnesium to 1mM (1.5 mM standard) resulted in minimal amplification, while only partial loss of yield was observed with 1.25 mM magnesium; (h) decreasing the annealing temperature by 2-4 degrees C did not generate artifacts or locus dropout and most laboratories observed full amplification with the annealing temperature increased by 2 degrees C and significant locus dropout with a 4 degrees C increase in annealing temperature; (i) amplification of individual loci with primers used in the multiplex produced the same alleles as observed with the multiplex amplification; (j) all laboratories observed full amplification with >or = 125 pg of male template with partial and/or complete profiles observed using 30-62.5 pg of DNA; (k) analysis of < or = 500 ng of female DNA did not yield amplification products; (l) the minor male component of a male/female mixture was observed with < or =1200-fold excess female DNA with the majority of alleles still observed with 10,000-fold excess female; (m) male/male mixtures produced full profiles from the minor contributor with 10-20-fold excess of the major contributor; (n) average stutter for each locus; (o) precision of sizing were determined; (p) human-specificity studies displayed amplification products only with some primate samples; and (q) reanalysis of 102 non-probative casework samples from 65 cases produced results consistent with original findings and in some instances additional identification of a minor male contributor to a male/female mixture was obtained. In general, the PowerPlex Y System was shown to have the sensitivity, specificity and reliability required for forensic DNA analysis.

Changes in the lipid composition of latent fingerprint residue with time after deposition on a surface

The work described in this report was focused on generating increased knowledge of fingerprint chemistry, particularly the composition of a latent fingerprint at the time it is deposited, and the chemical changes in lipid components that occur over time. Fingerprints from five male donors (aged 25-34 years) were collected and aged under controlled conditions. The prints were then sampled at set intervals, solvent extracted with dichloromethane, co-derivatized with MSTFA and analyzed by gas chromatography-mass spectrometry (GC-MS). It was shown that there was loss of squalene from prints stored in the light or in the dark. Loss was more rapid in the light, with squalene in prints from some donors not detected after 9 days storage. For these same donors, squalene was still detected after 33 days storage in the dark, but at much lower levels than in fresh prints. For saturated fatty acids (tetradecanoic, palmitic and stearic acid) there was a trend towards an increase in levels of these substances during storage (up to about 20 days) followed by a decrease back to original levels or below. This was the case for samples stored in the light or in the dark. For palmitoleic acid, a similar trend was seen. For oleic acid, this trend was seen for samples stored in the dark. For samples stored in the light the general trend was a decrease in level over the storage period (up to 33 days).
