Extensive studies have been carried out and theories expounded on leadership, yet no agreement has been reached on both definition and standards of leadership. The researcher takes the view that all the effort put on the study of leadership should have been directed toward the study of"followership". The characteristics and types of followers are central to the success of any leadership in the particular environment. In this study, followership is classified as voluntary and not coerced. The leadership would therefore depend on the nature of the followers and their expectations, meaning that followers predetermine the nature of leadership. Critical to this is the nature of the power used by the leader in relation to the power of the followers. A continuum of followership is constructed along the extremes of transactional and transformational leadership styles. The continuum is a useful tool and model for effective leadership, effective leadership is therefore dependent on the level of the maturity of the followers and the agreeableness and congruency between the leader and the followers. The article concludes that effectiveness of leadership is a direct result of the willingness of the followers to be led in that particular fashion. Broadly speaking, effective leadership styles are customised to meet the followers' demands and expectations.  相似文献

Identity is a critical developmental task during the transition to adulthood in Western societies. The purpose of the present study was to evaluate an empirically based, cluster-analytic identity status model, to examine whether all four of Marcia's identity statuses (diffusion, foreclosure, moratorium, and achievement) would emerge empirically, and to identify different patterns of identity formation among American college-attending emerging adults. An ethnically diverse sample of 9,034 emerging-adult students (73% female; mean age 19.73?years) from 30 U.S. universities completed measures of identity exploration (ruminative, in breadth, and in depth) and commitment (commitment making and identification with commitment), identity synthesis and confusion, positive and negative psychosocial functioning, and health-compromising behaviors. The identity status cluster solution that emerged provided an adequate fit to the data and included all four of Marcia's original identity statuses, along with Carefree Diffusion and Undifferentiated statuses. Results provided evidence for concurrent validity, construct validity, and practical applicability of these statuses. Implications for identity research are discussed.  相似文献

Abstract: Bloodstain pattern analysis can provide insight into a sequence of events associated with a violent crime. However, bloodstain pattern analysis can be confounded by the feeding activity of blow flies. We conducted two laboratory experiments to investigate the relationships between Lucilia sericata (green bottle fly) and Calliphora vicina (blue bottle fly), expirated bloodstains, and pooled bloodstains on a range of surfaces (linoleum, wallpaper, textured paint). C. vicina and L. sericata changed bloodstain pattern morphology through feeding and defecation. They also deposited artifacts in rooms where blood was not present originally. Chemical presumptive tests (Hemastix®, phenolphthalein, leucocrystal violet, fluorescein) were not able to differentiate between insect artifacts and bloodstains. Thus, C. vicina and L. sericata can confound bloodstain pattern analysis, crime scene investigation, and reconstruction. Crime scene investigators should be aware of these fundamental behaviors, and the effects that blow flies can have on expirated and pooled bloodstain patterns.  相似文献

Bloodstain pattern analysis can be critical to accurate crime scene reconstruction. However, bloodstain patterns can be altered in the presence of insects and can confound crime scene reconstruction. To address this problem, we conducted a series of controlled laboratory experiments to investigate the effect of Lucilia sericata (Meigen) on impact bloodstains and pooled bloodstains in association with three combinations of common surfaces (linoleum/painted drywall, wood floor/wallpaper, and carpet/wood paneling). L. sericata fed from the pooled bloodstains and added insect stains through regurgitation and defecation of consumed blood. L. sericata formed defecatory trails of insect stains that indicated directionality. Defecatory stains fluoresced when viewed at 465 nm with an orange filter. These observations differed from Calliphora vicina insect stains because feeding on blood spatter was not observed and trails of insect stains were formed by L. sericata. The fluorescence of defecatory stains can be used as a method to detect insect stains and discriminate them from real bloodstains.  相似文献

This study tested associations between problems in parent-youth relationships and problems with alcohol use among college students (N = 1592) using structural equation modeling. Hypotheses were that relationships between both substance-specific parenting factors (parental drinking) and non-substance-specific parenting factors (parental intrusive control and lack of support) and college student drinking behaviors would be mediated by the developmental tasks of managing difficult emotions and establishing a mature psychosocial identity. Sex, ethnicity and age were entered as control variables in the analyses and were tested for moderating effects. Results showed that the unconstrained model for males and females differed significantly from a model in which the two groups were constrained to be similar. Among young women, emotion regulation and psychosocial maturity were partial mediators of the effects of parent problems on alcohol use problems. Among young men, parent problems were indirectly related to alcohol use problems through emotion regulation. Implications for alcohol use prevention activities on college campuses are discussed. An earlier version of this paper was presented at the National Council on Family Relations Annual Meeting, November, 2004, Orlando, Florida. Research interests in college student alcohol misuse. Research interests in adolescent psychosocial maturity. Research interests in young adult relationships.  相似文献

A field experiment is reported that examines the advantages and disadvantages of two juror participation procedures: Allowing jurors to take notes during the trial, and allowing jurors to direct questions to witnesses. The presence or absence of both procedures was randomly assigned to 34 civil and 33 criminal trials in Wisconsin circuit courts. Following the trials, questinnaires were administered to judges, lawyers, and jurors. Overall, no evidence is found to support the hypotheses that juror notetaking would serve as a useful memory aid, would assist the jury with recall of the judge's instructions, or would increase the jurors' confidence in their verdict. The hypothesis that juror notetaking would increase juror satisfaction with the trial was supported. None of the findings supported the conclusion that juror notetaking was distracting, that notetakers were overly influential during the deliberations, that the jurors' notes were inaccurate, that the notes favored the plaintiff, or that the notes heightened juror disagreement about the trial evidence. It was hypothesized, but not found, that allowing juror questions of witnesses would uncover important issues in the trial and would increase the jurors' satisfaction with the trial procedure. However, juror questions did serve to alleviate juror doubts about the trial testimony, and provided the lawyers with feedback about the jurors' perception of the trial. No evidence was found to support the expectations that juror questions would slow the trial, would upset the lawyers' strategy, or that the question-asking procedure would be a nuisance to the courtroom staff. Furthermore, the lawyers did not appear overly reluctant to object to inappropriate questions from jurors, and jurors did not report being embarassed or angry when their questions were objected to.Dispute Resolution Research Center, Northwestern University  相似文献

This study addresses the question of whether the United States Supreme Court decision of Stone v. Powell, 428 U.S. 465 (1976), has had a significant impact on the highest level state appellate courts. The study centered around a survey sent to every member of the highest appellate court hearing criminal appeals in each of the fifty states. The major finding of the research was that Stone v. Powell can be viewed along two dimensions: a narrow, substantive dimension applying the case as a Fourth Amendment exclusionary rule decision, or a broader, policy dimension of judicial federalism. It appears that, for the most part, state supreme courts have chosen to apply Stone v. Powell along the narrow, substantive dimension. Thus, state supreme courts have not assumed the position of equal partners with the federal courts in assuring adequate and appropriate disposition of federal claims.  相似文献

Forensic scientists may encounter blood spatter at a scene which may be pure or a mixture of fly artifacts and human bloodstains. It is important to be able to make an informed identification, or at least advanced documentation of such stains since the mechanics of production of fly artifacts are not determinable to the crime scene reconstructionist from regular police forces. We describe three cases in which experiments and crime scene reconstruction led to additional information. Case 1: Above the position of a victim, numerous blood stains of the low-high-velocity type were found. Exclusion of these stains being caused by force (but instead caused by the activity of adult blow flies) by use of the following observations that were confirmed in experiments: (a) sperm-/tadpole-like structure with length > width, (b) random directionality, and (c) mixture of round symmetrical and teardrop shaped stains. Case 2: A reddish spatter field was found on a fan chain two rooms away from the place where a dead woman was found. Localization of the spatter on the bottom end of the surface hinted strongly towards fly activity. Case 3: Double homicide; submillimeter stains were found on a lamp between the two corpses. Activity of flies was less likely compared to alternative scenario of moving lampshade and violent stabbing.  相似文献
