青南地区牲畜营养与草地畜牧业可持续发展的探讨

分析了青南地区草地资源和繁殖母畜营养状况，指出人口的持续增长及对资源日益膨胀的需求与草地资源的有限性之间的矛盾是制约草地畜牧业可持续发展的首要因素。当前，应开展草地健康评价，平衡草畜营养，大力推进产业结构调整，走具有民族特色的草地畜牧业可持续发展道路。     

Creating a web of support: an important leadership strategy for advancing campus diversity

Research demonstrates that leadership, particularly among presidents, is important for moving a diversity agenda forward and make appreciable progress on it. The research questions pursued here are: What is the role of the college president in advancing a diversity agenda? What strategies do presidents identify as important to facilitating a diversity agenda? There were three main findings: (1) strategies are deployed in a non-linear way best represented through a web metaphor, (2) six sets of actors that serve as key nodes on the web and specific strategies were crucial to enhancing and deepening the web-developing an internal network, hiring, mentoring, partnering with faculty on the curriculum, supporting student affairs staff, working directly with and learning from students, and establishing external networks; and, (3) strategies within the human resource frame are noted by presidents as particularly important to moving a diversity agenda forward.

General population norms about child abuse and neglect and associations with childhood experiences

BACKGROUND: A variety of definitions of child abuse and neglect exist. However, little is known about norms in the general population as to what constitutes child abuse and neglect or how perceived norms may be related to personal experiences. METHODS: We conducted a random-digit-dialed telephone survey of 504 Washington State adults. Respondents were asked whether they believed each of 34 behaviors, identified in focus groups as possibly physically, sexually or emotionally abusive or neglectful, constituted abuse or neglect. Then, they were asked whether they had experienced 33 of the behaviors. RESULTS: Five of the six behaviors with the highest levels of consensus were for sexual abuse, whereas only one emotionally abusive behavior had a high level of consensus (95% agreement). Consensus that spanking constituted abuse increased with severity. Those respondents who reported experiencing a particular behavior were significantly less likely to believe the behavior abusive for 11 of the 33 behaviors and more likely to believe the behavior abusive for two of the behaviors. Where comparisons were possible, there was a high level of consensus that behaviors identified as abusive in Child Protective Service operational definitions constituted abuse. CONCLUSIONS: Self-reported childhood experiences were associated with perceived norms about child abuse. A better understanding of community norms about child abuse and neglect may be helpful in communicating with the public or allow for better targeting of educational messages through the media, parenting education classes, and so forth.     

Relaxation and guided imagery as an intervention for children with asthma: A replication

Asthma is a pervasive inflammatory disorder of the bronchial airways that causes the normal functioning of the airways to become overreactive. This disorder affects approximately 8 million children in schools per year and accounts for a significant amount of absences. Researchers have speculated that pharmacological interventions are alone insufficient or overaggressive in treating asthma, and numerous studies have demonstrated a connection between emotions and asthma. It has therefore been suggested that psychological interventions may be appropriate for this population. One such intervention, relaxation and guided imagery (RGI), that incorporates mental representations as well as the senses in a process of relaxing all the parts of the body has been shown to be effective with children with asthma. The current study served as a replication and extension of this previous research. The purpose of the investigation was to examine the effectiveness of RGI with an elementary school sample as well as determine the overall improvement in happiness, anxiety, and quality of life of the participants. Results demonstrated that RGI significantly improved the lung functioning of 3 out of 4 participants in the study. Furthermore, overall happiness improved for 1 participant in the study, state anxiety decreased for 2 of the 4 participants, and trait anxiety decreased for all 4 participants. © 2005 Wiley Periodicals, Inc.

The teaching of literature in a Singapore secondary school: disciplinarity,curriculum coverage and the opportunity costs involved

Set against the backdrop of reinvigorating the study of literature and concerns about the adequate preparation of students for the world of work, this paper explores how a Singapore teacher presented a literary text in the classroom. Drawing on data from a large-scale representative sample of Singapore schools in instruction and assessment practices, we discuss some of the potential consequences of instructional choice-making from a disciplinary perspective. Our findings suggest, for example, that when teacher-dominated discourse and interpretations dominate, instructional flexibility and responsiveness are correspondingly limited and restricted. These courses of action, we contend, may occur contrary to teachers’ plans and expectations. The paper closes by making a call for further longitudinal research across multiple research sites into the nature of literature pedagogy that has a strong disciplinary focus.     

Faculty ratings as a measure of departmental and administrator quality

This study examined the usefulness of faculty ratings as a measure of departmental quality. Two hundred and thirty-three faculty members from six departments responded to two questionnaires relating to the department—the Department Evaluation Survey (DES)—and to the department head—the Administrator Evaluation Survey (AES). A factor analysis of the DES revealed three underlying dimensions: Satisfaction with the Department's Academic Environment, Satisfaction with the Department's Governance and Operating Procedures, and Satisfaction with Student Quality. The factor analysis of the AES identified only one underlying dimension. Both the DES and AES were found to be highly reliable and effective in discriminating among departments. Very high positive correlations were also found between selacted DES and AES items suggesting that the performance of the head plays a very important role in faculty perceptions of the departments, and vice versa. Faculty ratings would appear to be a useful initial criterion in evaluating a department or head.
