The urine of individual dominant and subordinate male mice was tested for male-aversive and female-attractant properties using dominant and subordinate male donors and Ss and estrous and anestrous female Ss in open-field tests. The results indicate (1) the presence of a factor in the urine of dominant males which proves aversive to both dominant and subordinate Ss, (2) the presence of a female attractant in the urine of dominant males, (3) naive females must be in estrous to respond positively to male urine. The results are discussed in terms of preputial and coagulating gland contents, androgen levels, and possible territorial functions. 相似文献

This article serves as an introduction to log-linear analysis, a technique used in the analysis of qualitative data arranged in multidimensional contingency tables. The steps involved in log-linear analysis are presented in the context of an investigation of a personality characteristic of a group of counselor trainees. The references cited and supplemental readings allow interested readers to pursue the topic further. 相似文献

Promoting success for all students is the driving force to develop and implement sound teacher evaluation systems. As Stronge suggests, the two most frequently cited purposes of personnel evaluation are accountability and performance improvement (1997, p. 3). As a result, researchers are conceiving of teacher evaluation as a mechanism for improving teaching and learning (Danielson and McGreal, 2000). On the other hand, others affirm that the trend in teacher evaluation is toward more self-evaluation and expanding one's teaching repertoire (Association for Supervision and Curriculum Development, 1999, p. 8). However, teachers' voices relative to emerging teacher evaluation trends are missing. Thus, this study explored teachers' perceptions about the support for professional development available to them, the perceived potential benefits of a learner-centered teacher evaluation system to enhance their professional growth, and pitfalls. Only elementary school teachers participated in the study. The researcher analyzed teachers' written responses to open-ended questions, and generated categories by emerging themes to determine teachers' perceptions.Findings of the study suggest that teachers receive support from both campus level and central office level. Teachers also believe that a learner-centered teacher evaluation fosters walk-through observations, opportunities for professional growth, feedback, learner-centered dialogue, a holistic perspective, and teacher self-evaluation. On the other hand, findings suggest that teachers question the labels for each level of performance, and are concerned that the system might be somewhat subjective. Finally, suggestions are made to conduct additional studies to further illuminate teachers' voices associated with teacher evaluation and development at other school levels, and to expand our understanding of emerging teacher evaluation formats which aim at student success. 相似文献

The current state of childhood research is grounded in classical psychological theories, and Russian psychology is tied to cultural and historical theory in particular. These theories were invented to generalize and make sense of the realities of childhood as they existed at the time when these theories were created. Rapid social changes, especially during recent decades, have led to the emergence of a wide range of sources that bear witness to how the day-to-day life of childhood has changed. The understanding of childhood has continued to transform from one era to another. A metaphor was even coined to describe it, and at some point there was even a specific metaphor coined, “the disappearance of childhood.” This article seeks to explore how the image of childhood has changed in relation to the image of adulthood. As material for analysis, we chose Soviet and Russian movies from the 1940s to 2000s. The study is based on the assumption that a sequential analysis based on Yuri Lotman’s theory of the structure of the text demonstrates how the image of childhood changes over time. If in the 1940s and 1950s the child was presented as immature and not quite grown up, the adult was portrayed as the embodiment of the ideal form of the individual, and the main conflict was structured around childish immaturity, then gradually over the decades more and more main characters who were children and adults were portrayed as different kinds of individuals, and the child (or teenager) sometimes came to embody obviously negative features. The child–adult dichotomy itself lost its significance. 相似文献

Fatigue represents a reduction in the capability of muscle to generate force. The aim of the present study was to establish the effects of exercise that simulates the work rate of competitive soccer players on the strength of the knee extensors and knee flexors. Thirteen amateur soccer players (age 23.3+/-3.9 years, height 1.78+/-0.05 m, body mass 74.8+/-3.6 kg; mean+/-s) were tested during the 2000-2001 soccer season. Muscle strength of the quadriceps and hamstrings was measured on an isokinetic dynamometer. A 90 min soccer-specific intermittent exercise protocol, incorporating a 15 min half-time intermission, was developed to provide fatiguing exercise corresponding in work rate to a game of soccer. The exercise protocol, performed on a programmable motorized treadmill, consisted of the different intensities observed during soccer match-play (e.g. walking, jogging, running, sprinting). Muscle strength was assessed before exercise, at half-time and immediately after exercise. A repeated-measures analysis of variance showed significant reductions (P < 0.001) in peak torque for both the quadriceps and hamstrings at all angular velocities (concentric: 1.05, 2.09, 5.23 rad x s(-1); eccentric: 2.09 rad x s(-1)). The peak torque of the knee extensors (KE) and knee flexors (KF) was greater before exercise [KE: 232+/-37, 182+/-34, 129+/-27, 219+/-41 N x m at 1.05, 2.09 and 5.23 rad x s(-1) (concentric) and 2.09 rad x s(-1) (eccentric), respectively; KF: 126+/-20, 112+/-19, 101+/-16, 137+/-23 N x m] than at half-time (KE: 209+/-45, 177+/-35, 125+/-36, 214+/-43 N x m; KF: 114+/-31, 102+/-20, 92+/-15, 125+/-25 N x m) and greater at half-time than after exercise (KE: 196+/-43, 167+/-35, 118+/-24, 204+/-43 N x m; KF: 104+/-25, 95+/-21, 87+/-13, 114+/-27 N x m). For the hamstrings:quadriceps ratio, significant changes were found (P < 0.05) for both legs, the ratio being greater before than after exercise. For fast:slow speed and left:right ratios, no significant changes were found. We conclude that there is a progressive reduction in muscle strength that applies across a range of functional characteristics during exercise that mimics the work rate in soccer. 相似文献

Nonsuicidal self‐injury (NSSI) is a maladaptive coping strategy that is of significant clinical concern for behavioral health professionals in college settings. Relationships between NSSI, acquired capability for suicide, interpersonal cognitions, and five‐factor model personality traits were assessed in a survey‐based study that included 192 young adults in a college setting. Results indicated that those with an affirmative suicide attempt history, greater acquired capability for suicide, and elevated neuroticism had an increased likelihood of lifetime NSSI. 相似文献

Two experiments examined whether 18-month-olds learn from emotions directed to a third party. Infants watched an adult perform actions on objects, and an Emoter expressed Anger or Neutral affect toward the adult in response to her actions. The Emoter then became neutral and infants were given access to the objects. Infants' actions were influenced by their memory of the Emoter's affect. Moreover, infants' actions varied as a function of whether they were currently in the Emoter's visual field. If the previously angry Emoter was absent (Experiment 1) or turned her back (Experiment 2), infants did not use the prior emotion to regulate their behavior. Infants learn from emotional eavesdropping, and their subsequent behavior depends on the Emoter's orientation toward them. 相似文献
