Does majoring in criminal justice affect perceptions of criminal justice     

Olga Tsoudis 《Journal of Criminal Justice Education》2013,24(2):225-236

Research continues to show that the public holds misperceptions about crime and criminal justice. The media influences the public in many of these misperceptions, often shaping beliefs and ideologies. Higher education gives criminal justice majors the opportunity to gain much more accurate knowledge than the general public. Nonetheless, it is the public that heavily influences the development of the criminal justice system. It is important, therefore, to examine the influence of criminal justice education. Criminal justice majors and non-majors in a Midwestern university were surveyed with regard to demographics and perceptions of crime and criminal justice. Results indicate that criminal justice majors have significantly different perceptions about criminal justice issues than non-majors. Implications for educating the public are discussed.  相似文献

ABSTRACT

Para Va’a is a new Paralympic sport in which athletes with trunk and/or leg impairment compete over 200 m. The purpose of this study was to examine the impact of impairment on kinematic and kinetic variables during Va’a ergometer paddling. Ten able-bodied and 44 Para Va’a athletes with impairments affecting: trunk and legs (TL), legs bilaterally (BL) or leg unilaterally (UL) participated. Differences in stroke frequency, mean paddling force, and joint angles and correlation of the joint angles with paddling force were examined. Able-bodied demonstrated significantly greater paddling force as well as knee and ankle flexion ranges of movement (ROM) on the top hand paddling side compared to TL, BL and UL. Able-bodied, BL and UL demonstrated greater paddling force and trunk flexion compared to TL, and UL demonstrated larger bottom hand paddling side knee and ankle flexion ROM compared to BL. Significant positive correlations were observed for both male and female athletes between paddling force and all trunk flexion angles and ROM in the trunk and pelvis rotation and bottom hand paddling side hip, knee and ankle flexion. The results of this study are important for creating an evidence-based classification system for Para Va’a.  相似文献   

‘We've Already Done that One’: Adolescents' Repeated Encounters with the Same Artwork     

Olga M. Hubard 《The International Journal of Art & Design Education》2006,25(2):164-174

This article explores the way young people's responses to an image evolve when they engage with it repeatedly. An analysis of the sequential encounters of six adolescents with a Renaissance painting reveals that, as they gained experience with the picture, the youngsters probed for increasingly deeper layers of meaning in the work. Specifically, on their second encounter with the painting, the students showed greater sensitivity to visual information, and they incorporated their own experiences and knowledge into the meaning‐making process more actively than on their first encounter. This study also shows that, once the participants had established a relationship with the artwork on their own terms, they seemed eager to discover contextual information about it. However, far from accepting this information as ‘authority’, the young viewers considered it critically and used it to deepen, expand and revise their personal visions of the painting.  相似文献

Vagal Reactivity and Affective Adjustment in Infants during Interaction Challenges   总被引：2，自引：0，他引：2  

Olga V. Bazhenova  Oxana Plonskaia  & Stephen W. Porges 《Child development》2001,72(5):1314-1326

Respiratory sinus arrhythmia (RSA) and heart period were evaluated in 5-month-old infants (N = 40) during interaction challenges requiring affective adjustment. The paradigm consisted of four 2-min experimental conditions designed to elicit behavioral and autonomic responses to object-mediated (Picture Attention and Toy Attention) and person-mediated (Still Face and Social Interaction) engagement. The data demonstrated that autonomic state systematically changed during engagement and disengagement with the environment. During the object-mediated challenge, increases in RSA were uniquely related to positive engagement. During the person-mediated challenge, there was a more complex integration of autonomic and behavioral responses characterized by concordant increases and decreases in RSA, heart period, positive engagement, negative affect, and motor activity. When participants were partitioned into two groups, based on their RSA response pattern during the person-mediated challenge, only participants who exhibited a pattern of RSA decrease from Toy Attention to Still Face followed by a rapid recovery during Social Interaction demonstrated regulation of behavioral activity, including concordant recovery from stress. These findings provide additional empirical support for the role of vagal regulation of the heart in the modulation of affective adjustment and engagement behavior.  相似文献   

Exploring French adolescents’ and adults’ comprehension of the greenhouse effect     

Sören Frappart  Mylène Moine  Saïd Jmel  Olga Megalakaki 《Environmental Education Research》2018,24(3):378-405

The aim of the present study was to gain an insight into French young people’s conceptual development regarding the greenhouse effect. Because this effect cannot be directly manipulated, we can assume that its conceptualization is mainly shaped through the sharing of information. Eighty French students from Grade Seven through to adulthood responded to statements in a questionnaire on the greenhouse effect’s causes, consequences and solutions. Unlike in previous studies, participants were asked to justify their choices, as some of the statements were quite complex. Results showed that performances improved with grade, mainly between Grade Nine and adulthood, although participants continued to have a weaker grasp of the causes of the greenhouse effect than of its consequences and solutions. Participants’ justifications also showed that they misunderstood some of the statements.  相似文献

Early Childhood Education in Societal Context: Teachers in Three Countries Speak About Early Childhood Education     

Helen L. Carlson  Olga Zvagina  Lena Stenmalm Sj  lom 《Early education and development》1997,8(2):169-186

Building on the cross-cultural patterns and systems research as well as social constructivism, in-depth interviews were conducted with key informant early childhood teachers in three regions with similar characteristics in Sweden, Russia, and in the United States. Inductive analyses revealed differences in responses among Swedish, Russian and American informants related to the macro-, meso-, and micro-levels of societal system. United States teacher informants had a great number of separate topic comments and distributed them more evenly across all levels than did Russian and Swedish teacher informants who had more emphasis at the meso level. United States and Russian teacher informants discussed the lack of societal support for young children and their families, while Swedish teacher informants seemed to almost take this support for ranted. United States teacher informants suggested that early childhood programs were important in developing support networks among parents, while Russian teacher informants often gave information to parents and Swedish teachers spoke about mutually sharing information. United States teacher informants desired both strict rules with strong academic content and extension of the child's initiations through play; they emphasized activities and materials. Swedish teachers discussed a child- centered approach to social learning and creativity and desired to be with children rather than do activities with them. Russian teacher informants emphasized the importance of obedience, aesthetic education, and preparation for school and the labor of the larger society. These study outcomes deepen understanding about the multidemensional relationships between early childhood programs and societal contexts in which they are embedded, and they suggest alternative approaches to working with young children and their families.  相似文献   

Peer bullying,self-serving cognitive distortions and school moral climate perception in Spanish and Dutch secondary school students / Acoso escolar,distorsiones cognitivas en beneficio propio y percepción del clima moral escolar en estudiantes de secundaria de España y Holanda     

Kevin van der Meulen  Daniel Brugman  Olga Hoyos  Cristina del Barrio 《Infancia y Aprendizaje》2019,42(2):337-373

Students’ role in traditional bullying and cyberbullying was investigated in relation to self-serving cognitive distortions (SSCD), perception of school moral climate and bullying observation. Participants were secondary school students from Spain (n = 568; 286 girls) and the Netherlands (n = 421; 223 girls). The results demonstrated that in both country samples, bullies and bully-victims had higher levels of SSCD. Both Spanish and Dutch students who were directly involved in traditional bullying situations showed more negative perceptions of the school moral climate. In cyberbullying situations, bystanders scored higher on school moral climate perception than bullies and bully-victims. Furthermore, school moral climate perception was negatively associated with traditional bullying observation in the group of victims, and with cyberbullying observation in the case of victims and bystanders. The present findings suggest that future research should focus on the cause-effect relations of these factors, which could include measuring the effects on bullying prevalence of an intervention aimed at SSCD reduction in bullies and bystanders and the improvement of the school moral climate.  相似文献   

Multiple-pair training enhances transposition in pigeons     

Lazareva OF  Miner M  Wasserman EA  Young ME 《Learning & behavior》2008,36(3):174-187

We studied transposition in pigeons by training them to select the smaller (or the larger) of a pair of circles. In training, different groups of pigeons were given one pair, two pairs, or three pairs of circles along the size dimension. Testing included two stimulus pairs for which, according to theoretical postdiscrimination generalization gradients, transposition should decrease from one-pair to two-pair to three-pair training. On the basis of the results of our earlier study (Lazareva, Wasserman, & Young, 2005) and contrary to these predictions, we expected that transposition should increase from one-pair to two-pair to three-pair training. We found that multiple-pair discrimination training enhanced transposition, which, on average, rose from 47% (one-pair training) to 52% (two-pair training) to 64% (three-pair training). In addition, we found that the overall similarity of the testing pair to the training pair(s) modulated the strength of relational responding. These results demonstrate that encountering multiple instances of a rule leads to stronger relational learning, even when reinforcement history predicts the opposite trend. These results also provide strong evidence against stimulus generalization as the sole determinant of relational responding in transposition.  相似文献
