The practice of 'Management by Contract' can — as with any practice — be characterized by programmatic and technological dimensions. These dimensions contain concepts and ideas at the programmatic level, which shape the mission of the practice (concrete tasks and routines) at the technological level. Thus, the former attach the practice to the broader conceptual dimension. In this paper both of these dimensions will be analysed. The aim is to study how quality issues have been managed by contract. The first part presents some of the conceptual arguments of 'Management by Contract'. The arguments of a structure generally used (the Purchaser/Provider split) and a method often used (competitive tendering) will be discussed. The second part presents some technological effects through empirical findings. The paper concludes with an analysis of the interaction or non-interaction between these two dimensions.  相似文献

Sommaire: Dans cet article sur l'évaluation, l'auteur constate d'abord que les organismes conseils en éducation dénoncent chacun à leur manière l'absence d'évaluation dans les établissements scolaires. Il présente ensuite les conditions selon lesquelles l'évaluation peut éclore et se développer: la restauration du sens de I'institution; la recherche de l'excellence; le dépassement des idéologies; l'élimination des rapports conflictuels. L'auteur aborde dans une deuxième partie le champ d'application de l'évaluation scolaire: I'évaluation des apprentissages; l'évaluation des enseignants; l'évaluation de la gestion administrative. Finalement, l'auteur propose à la réflexion les pistes suivantes: l'évaluation, c'est d'abord le pari de l'excellence; l'èvaluation ne peut se faire sans un changement des mentalités; l'évaluation exige l'ouverture vers I'extéieur. Enfin, I'auteur dénonce la culture de la peur que les détracteurs de l'évaluátion entretiennent volontiers pour retarder l'action et il incite les administrateurs scolaires à mener de façon concrète et active leur intervention dans ce domaine. Abstract: In this paper on evaluation or assessment, the author first notes that educational organizations all criticize, in their own way, the lack of evaluation in school establishments. He then specifies the conditions under which such evaluation may emerge and develop: the sense of purpose of the institution must be restored; there must be a search for excellence; one must go beyond ideology; conflict relationships must be eliminated. In part two, the author deals with the fields of application of school evaluation: assessing trainee programs; evaluating teachers; assessing administrative management, The author then suggests the following matters for thought: to evaluate is first of all to search for excellence; no assessment can be made without changes in mentality; and assessment requires an open outlook. Lastly, the author decries the fact that the detractors of evaluation resort to fear as a dilatory measure against action. He urges school administrators to define, in a concrete, active manner, their role in this area.  相似文献

Background

Recent field research has demonstrated that an attraction to aggressive behavior and cruelty is common among combatants and perpetrators involved in organized violence. The biological basis of this appetitive perception of aggression in humans has to date not been studied.

Aims

We examined testosterone as a potential hormonal moderator during induction of specifically appetitive aggressive behavior in the laboratory.

Method

To activate physiological responding related to appetitive aggression, 145 university students (72 women) listened to tape recordings of variants of a violent story. The perspective of the listener in the story was randomized between subjects. Participants were required to either identify as perpetrator, neutral observer, or victim. We assessed changes in saliva testosterone in response to the story. Subsequently, a series of pictorial stimuli (IAPS) with different valence ratings was presented and participants determined the length of viewing time with a button click. This viewing time for negative IAPS was assessed as a dependent variable indicating level of interest in violent scenes.

Results

Men identified themselves with the perpetrator more than women irrespective of the particular perspective presented by the story. Men who responded with an increase in saliva testosterone when adopting the perpetrator perspective chose to view the negative IAPS pictures for longer intervals than participants in other conditions or those who did not exhibit a release in testosterone.

Conclusions

Testosterone moderates attraction to cruel and violent cues in men, as indicated by extended deliberate viewing of violence cues.  相似文献

This article deals with certain matters concerning the issue of the political accountability of ministers to parliament during the last twenty years of the reign of King George II. It emphasizes the fact that there was no constitutional convention during this period that would have allowed parliament or the House of Commons alone to force the dismissal or resignation of ministers (as the ultimate sanction of political accountability). At that time, the king was the real master of his ministers. On the other hand, and as a matter of fact, only those ministers who could best manage the king's business in parliament were kept in office by the king. These propositions are demonstrated by examining the practice of the various administrations between 1740–60. It was also especially important for the leading ministers, such as Robert Walpole, Henry Pelham, the Duke of Newcastle and William Pitt to secure both the favour of the king and the confidence of parliament to remain in office. The Pitt-Newcastle administration (from 1757) additionally confirmed the general principle in times of war that administrations can only have firm parliamentary majorities to hold onto power as long as they would lead a war successfully.  相似文献

Hypoglycemia was long considered to kill neurons by depriving them of glucose. We now know that hypoglycemia kills neurons actively from without, rather than by starvation from within. Hypoglycemia only causes neuronal death when the EEG becomes flat. This usually occurs after glucose levels have fallen below 1 mM (18 mg/dl) for some period, depending on body glycogen reserves. At the time that abrupt brain energy failure occurs, the excitatory amino acid aspartate is massively released into the limited brain extracellular space and floods the excitatory amino acid receptors located on neuronal dendrites. Calcium fluxes occur and membrane breaks in the cell lead rapidly to neuronal necrosis. Significant neuronal necrosis occurs after 30 min of electrocerebral silence. Other neurochemical changes include energy depletion to roughly 25% of control, phospholipase and other enzyme activation, tissue alkalosis and a tendency for all cellular redox systems to shift towards oxidation. The neurochemistry of hypoglycemia thus differs markedly from ischemia. Hypoglycemia often differs from ischemia in its neuropathologic distribution, a phenomenon applicable in forensic practice. The border-zone distribution of global ischemia is not seen, necrosis of the dentate gyrus of the hippocampus can occur and a predilection for the superficial layers of the cortex is sometimes seen. Cerebellum and brainstem are universally spared in hypoglycemic brain damage. Hypoglycemia constitutes a unique metabolic brain insult.  相似文献

The use of a QIAamp DNA Stool Mini Kit (QIAGEN) for extracting human nuclear DNA from feces samples is reported. This method employs a stool lysis buffer and a unique matrix (InhibitEX tablet) to remove PCR inhibitory substances specific to feces samples. DNA extracted from various amounts of stool and from stool samples exposed to different environmental impacts was successfully amplified and typed using the Profiler Plus Amplification Kit and ABI PRISM 310 Genetic Analyser.  相似文献

Uniform Crime Reports (UCR) arrest and offense data for Chicago for 1960 to 1980 and population data from the 1960, 1970, and 1980 censuses are used to assess the extent to which demographic changes help explain trends in the city's homicide and robbery arrests. The results indicate that a changing racial composition contributed to changes in the age composition of Chicago's population as well as to changes in the homicide rate. Age-specific analysis by race and gender suggests that as much as 24% of the total increase in homicide arrests and 45% of the increase in robbery arrests (from 1962 to 1980) can be attributed to an increase in the number of nonwhite men in the population. Increasedrates of arrest of nonwhite men appear to account for large parts of the increases in homicide and robbery arrests, with increased rates for white men and nonwhite women also accounting for some of these increases. The paper closes with a discussion of the issues raised by these trends for Chicago and other urban areas.Revision of a paper presented at the 1984 Annual Meeting of the American Society of Criminology, Cincinnati.  相似文献

Dispositional Sensitivity to Befallen Injustice   总被引:1,自引:0,他引:1  
Dispositional Sensitivity to Befallen Injustice (SBI) is proposed as a new construct. A self-report questionnaire with four types of indicators (frequency, intensity of anger, intrusiveness of thoughts, punitivity) was developed for measuring SBI. Using structural equation modeling and the general rationale of multitrait-multimethod analysis, the convergent and discriminant validity of this questionnaire was investigated vis-à-vis measures for Trait Anger, Anger In, Anger Out, and Frustration Tolerance as related constructs. Additionally, a meaningful pattern of correlations was obtained between SBI and Life Satisfaction, Centrality of Justice, Interpersonal Trust, and Need for Control. Finally, self-reported sensitivity to befallen injustice was found to predict cognitive, emotional, and behavioral reactions to unjust treatment in laboratory and natural settings several weeks later.  相似文献

Fingerprinting brushes have the potential to collect and transfer DNA during powdering. Squirrel-hair fingerprint brushes exposed to specific sets of saliva stains and brushes used in routine casework were tested for their ability to collect and transfer DNA containing material using standard DNA extraction procedures and AmpFlSTR Profiler Plus amplification and typing procedures. The tests found that the risk of transferring DNA during powdering and having a detrimental impact on the analysis increases if the examiner powders over either biological stains (such as blood or saliva) or very fresh prints and uses more sensitive PCR amplification and typing procedures. We advocate caution when powdering prints from which DNA may also be collected and provide options for consideration to limit the risk of transferred DNA contamination while fingerprinting.  相似文献
