Examining the developmental trajectories of adolescent sexual offenders     

Lesleigh E. Pullman  Elisabeth J. Leroux  Gregory Motayne  Michael C. Seto 《Child abuse & neglect》2014

The aim of the current study was to assess the validity of the sex-plus versus sex-only categorization method for distinguishing between different types of adolescent sex offenders (ASOs; Butler & Seto, 2002). It is hypothesized that this categorization method has utility when attempting to distinguish between generalist and specialist ASOs (Seto & Pullman, 2014). Additionally, further classification of ASOs was attempted using a well known juvenile delinquency classification scheme, early-onset versus late-onset offenders (Moffitt, 1993). The current study was an archival analysis of clinical files from a sample of 158 male ASOs seen for clinical assessment at a Metropolitan Family Court Clinic. Results indicate that sex-plus offenders are more antisocial, exhibit more psychiatric issues, and have greater deficits in general social skills compared to sex-only offenders. Conversely, sex-only offenders were found to have more atypical sexual interests, and were more likely to have greater deficits in romantic relationships compared to sex-plus offenders. Due to a power related limitation, little support was found for the use of the early-onset versus late-onset classification scheme with ASOs. Overall, these results provide further support to the validity of a sex-only versus sex-plus distinction. Given these results mirror those found in the generalist/specialist literature regarding the etiology of ASOs, sex-only and sex-plus offenders may indeed have different etiological pathways: sex-plus offenders are more driven by general antisociality factors, as the generalist perspective suggests, and sex-only offenders are more driven by special factors, as the specialist explanations suggest.  相似文献   

The relationship between the developmental level of persuasive strategies and their effectiveness     

Gregory J. Shepherd  Barbara J. O'Keefe 《Communication Studies》2013,64(3):137-152

Research on the development of persuasive communication skills has described the emergence of four basic strategies in persuasive messages. This study includes two experiments to assess the role these strategies play in the process of gaining compliance. In both, college students received messages requesting they volunteer for an experiment and advocating compliance. Messages differed in the level of strategic adaptation of the compliance‐gaining appeal they offered. In general, form of request (supported versus unsupported) and content of specific message appeals influenced compliance, but level of strategic adaptation made little or no contribution to message effectiveness.  相似文献   

Anxiety,construct differentiation,and message production     

Gregory J. Shepherd  Mollie B. Condra 《Communication Studies》2013,64(3-4):176-189

Neuliep and Hazleton have reported a significant negative relationship between a general measure of trait anxiety and interpersonal construct differentiation. The study reported in this paper failed to find a significant relationship between a more specific measure of interpersonal trait anxiety and interpersonal construct differentiation, and also found no significant relationships between state anxiety and construct differentiation, or either interpersonal trait or state anxiety and the production of messages considered more or less competent by constructivist conceptions in an anxiety‐producing interpersonal context. The study did find a significant positive relationship between interpersonal construct differentiation and the production of such messages. These results are discussed with particular emphasis on the lack of conceptual relation between notions of anxiety and construct differentiation.  相似文献   

Communication as influence: Definitional exclusion     

Gregory J. Shepherd 《Communication Studies》2013,64(4):203-219

Persuasion, influence, and power have traditionally been defined as the fundamental features of rhetoric, communication, and discourse. This tradition of definition exhibits a masculine bias that has tended to exclude and negate a feminine view of communication as relational responsibility. This essay calls for the development of a transcendent definition of communication that will include and affirm both masculine and feminine views, leading to more favorable pragmatic, theoretic, and research consequences.  相似文献

An Examination of Aggression and Adaption Traits with Moral Foundation     

Gregory A. Cranmer  Matthew M. Martin 《Communication Research Reports》2013,30(4):360-366

ABSTRACT

Moral Foundation Theory forwards that morality is a traitlike disposition that guides one's behaviors, attitudes, and communication. This study examined the relationship between participants' moral foundations and their aggressive and adaptation communication traits. Results of this study suggest that the foundations that concern others (i.e., harm/care and fairness/reciprocity) were associated negatively to verbal aggressiveness, argumentativeness, and Machiavellianism and associated positively with responsiveness, assertiveness, and cognitive flexibility. The foundations that concern socially binding constructs (i.e., in-group/loyalty, authority/respect, and purity/sanctity) were negatively related to Machiavellianism and cognitive flexibility.  相似文献   

Provo City Library: Building across a Century     

Gregory M. Nelson 《Public Library Quarterly》2013,32(2):159-180

The public library in Provo City, Utah, has undergone significant changes since the founding of the original 1906 building that was funded by Andrew Carnegie. The library has changed according to the needs of the community as it has adapted from its pioneer heritage to a modern service-information organization. As it has adapted, however, the Provo Library has maintained its focus on community service with its physical facilities, collection development, community outreach, and quality staffing.  相似文献   

Innovations in Measuring Rater Accuracy in Standard Setting: Assessing “Fit” to Item Characteristic Curves     

Gregory M. Hurtz  J. Patrick Jones 《教育实用测度》2013,26(2):120-143

Standard setting methods such as the Angoff method rely on judgments of item characteristics; item response theory empirically estimates item characteristics and displays them in item characteristic curves (ICCs). This study evaluated several indexes of rater fit to ICCs as a method for judging rater accuracy in their estimates of expected item performance for target groups of test-takers. Simulated data were used to compare adequately fitting ratings to poorly fitting ratings at various target competence levels in a simulated two stage standard setting study. The indexes were then applied to a set of real ratings on 66 items evaluated at 4 competence thresholds to demonstrate their relative usefulness for gaining insight into rater “fit.” Based on analysis of both the simulated and real data, it is recommended that fit indexes based on the absolute deviations of ratings from the ICCs be used, and those based on the standard errors of ratings should be avoided. Suggestions are provided for using these indexes in future research and practice.  相似文献

Atomic theory or the nature of matter is a principal concept in science and science education. This has, however, been complicated by the difficulty students have in learning the concept and the subsequent construction of many alternative models. To understand better the conceptual barriers to learning atomic structure, this study explores the troublesome nature of this fundamental scientific concept. In order to illustrate the distinction of student understanding by threshold barriers, this study chose three particularly high‐achieving students from an original interview sample of 20 students who were selected from an introductory college chemistry course. The pre‐course and post‐course interview responses were examined and compared in detail. This study considers the concepts of ‘probability’ and ‘energy quantization’ to both describe the structure of the threshold of understanding students’ need to negotiate in their construction of the target model of atomic structure. In this respect, this study suggests atomic structure as a possible threshold concept for further study in science. Identifying the nature and structure of the threshold of understanding confronting students, and analyzing the troublesomeness of atomic structure, provides valuable information for understanding student learning difficulties, and insight into how they may be addressed.  相似文献
