Culture Change Refined and Revitalized: The Road Show and Guides for Pragmatic Action

Despite a declining interest in the relationship between leadership, culture, and performance in the scholarly literature, culture change is alive and well among leaders in the public sector as a means to improve performance. This essay reviews the trajectory of culture studies and proposes a modest model of organizational culture that sets aside many of the conceptual and methodological arguments about culture, focusing instead on what leaders actually do to change culture. The model is examined in the context of organizational culture change efforts in the city of Alexandria, Virginia. Several practical and theoretical insights are offered from this pragmatic and leadership‐focused approach to culture.     

Are current aid strategies marginalising the already marginalised? Cases from Tanzania

Engaging with and assisting marginalised communities remains a major challenge for governments of developing countries, as many national development strategies tend in practice to further marginalise chronically poor communities. Development aid strategies, including poverty-reduction initiatives, have focused primarily on economic development. As a result they have contributed to the erosion of the asset base of these communities, and in particular their access to natural resources. While questioning the impact of aid arrangements on the poorest and most vulnerable communities in society, this article recognises that current aid arrangements, such as national poverty-reduction strategies, have created an environment in which chronic poverty can be addressed by national governments and other stakeholders. The authors emphasise the need for greater sensitivity in the processes of planning and managing national development strategies that seek to reduce poverty, as well as a commitment to institutional arrangements that include marginalised groups in the country's political economy.     

A Critical Appraisal of the Statecraft Interpretation

This article subjects the Statecraft interpretation to critical assessment. It argues that, while Bulpitt has provided a parsimonious and stimulating contribution to our understanding of British politics, his work needs to be developed. More specifically, although the Statecraft thesis evolved out of Bulpitt's concerns with the methodology of political science, a neglect of ontological and epistemological questions has led it to propound explanations which are both reductionist and insensitive to empirical criticism. The article concludes by suggesting ways in which the Statecraft interpretation can be developed to take account of these weaknesses.     

Correctional employees' reactions to job characteristics: A data based argument for job enlargement

Job enlargement, an industrial organization innovation that allows workers (within limits) greater responsibility for their jobs is explored and discussed in relation to correctional personnel. Based on responses to tests administered to 104 correctional personnel in a Midwestern state, it was found that industrial findings generalize to corrections.Job enlargement is recommended to improved the personnel and managerial aspects of the correctional institution, to bring the institution into conformity with environmental reality, and to overcome the therapy-custody dichotomy.     

A study of business letter features

As part of their work, forensic document examiners examine word processed letters. The purpose of this study, the first of its kind, was to determine how common or rare certain features are in word-processed business letters and if any of these features could determine the author or source. Initially, 114 original business letters were obtained that were dated from 1999 through 2003. Specific features of the letters were selected for examination. These features were letter format, type style, the point size of the font, margin spacing to ascertain the use or nonuse of the default margins for Word (1.25 in. nonjustified) and the default margins for WordPerfect (1 in. nonjustified). In addition, the research involved the examination of the right margins to determine if they were justified or not and the use of the comma or colon in the salutation of the letter. The features of each letter were independently examined by the authors and the findings documented. As expected, several features were found to be very common. For example,full block format was used on 48% of the letters followed by the semi-block with 39%. The Times Family of fonts was used on 67% of the letters. Font point size 12 was the most popular with 70%. The nonjustified default margins were widespread with 67% and the colon was the overwhelming favorite in the salutation with 79%. There were some unexpected findings that could possibly lead to the identification of a source or typist.     

Chest deflection tolerance to blunt anterior loading is sensitive to age but not load distribution

Ninety-three human cadaver tests are used in the development of thoracic injury risk functions with consideration of age and restraint condition. Linear logistic regression models are developed with the set of potential predictors including the maximum chest deflection, the age of the cadaver at death, gender, and the loading condition on the anterior thorax: blunt hub (41 tests), seat belt (26 tests), air bag (12 tests), and combined belt-and-bag (14 tests). Predicted outcomes were the probability of any rib fractures (onset of injury) and the probability of greater than six rib fractures (severe injury). The analysis shows that the injury risk function was not dependent on the loading condition, but was strongly dependent on age. A significant injury risk model with good ability to discriminate injury from non-injury tests (P < 0.0001, chi-square = 21.49, area under receiver operator characteristic curve (ROC) = 0.867, Kruskal's Gamma = 0.732) is presented using only maximum chest deflection and cadaver age as predictors of injury risk. The 50% risk of any rib fractures is found to occur at 35% chest deflection for a 30-year-old, but at 13% deflection for a 70-year-old. The 50% risk of severe injury is shown to occur at 33% chest deflection for a 70-year-old, but at 43% for a 30-year-old.     

Synchronization of the acoustic evidence in the assassination of President Kennedy

We have revisited the acoustic evidence in the Kennedy assassination--recordings of the two Dallas police radio channels upon which our original NRC report (Ramsey NF et al., Report of the Committee on Ballistic Acoustics. National Research Council (US). Washington: National Academy Press, 1982. Posted at http://www.nap.edu/catalog/10264.html) was based--in response to the assertion by DB Thomas (Echo correlation analysis and the acoustic evidence in the Kennedy assassination revisited. Science and Justice 2001; 41: 21-32) that alleged gunshot sounds (on Channel 1), apparently recorded from a motorcycle officer's stuck-open microphone, occur at the exact time of the assassination (as established by emergency communications on Channel 2). We have critically reviewed these two publications, and have performed additional analyses. In particular we have used recorded 60 Hz hum and correlation methods to obtain accurate speed calibrations for recordings made on both channels, cepstral analysis to seek instances of repeated segments during playback of Channel 2 (which could result from groove jumping), and spectrographic and correlation methods to analyze instances of putative crosstalk used to synchronize the two channels. This paper identifies serious errors in the Thomas paper and corrects errors in the NRC report. We reaffirm the earlier conclusion of the NRC report that the alleged "shot" sounds were recorded approximately one minute after the assassination.     

School Violence Prevention: Current Status and Policy Recommendations

The purpose of this article is to identify an array of strategies that are available to schools to address concerns school violence and to identify some of the potential school or school district policy options related to those choices. We illustrate that many promising options are available to schools to address violence and other inappropriate behavior of students. The very breadth and diversity of these options may pose a problem in attempting to develop a comprehensive local policy on this topic. While many schools have chosen increasingly punitive zero‐tolerance policies as their primary strategy of violence prevention, there is little or no research evidence documenting that such an approach can contribute to school safety. Rather, effective school violence prevention requires comprehensive planning involving documented best‐practice programs, preventive strategies, and effective responses to any violence that may occur. Since research documenting the effects of violence prevention strategies is inconsistent, it is incumbent upon schools to consider carefully which programs best meet the needs of their local situation, and to monitor the effectiveness of new programs in improving school safety and reducing disruption and incivility.
