Boundaries,breaches, and bridges: The case of Climategate

We examine the incident known as “Climategate” in which emails and other documents relating to climate scientists and their work were illegitimately accessed and posted to the Internet. The contents of the files prompted questions about the credibility of climate science and the legitimacy of some of the climate scientists’ practices. Multiple investigations unfolded to repair the boundary that had been breached. While exonerating the scientists of wrongdoing and endorsing the legitimacy of the consensus opinion, the investigating committees suggested revisions to some scientific practices. Despite this boundary repair work, the credibility and legitimacy of the scientific enterprise were not fully restored in the eyes of several stakeholders. We explore why this is the case, identify boundary bridging approaches to address these issues, and highlight policy implications.     

Facing Facts: Can the Face-Name Mnemonic Strategy Accommodate Additional Factual Information?

In 3 experiments, undergraduates used their own best method (control) or an “imposed” face-name mnemonic strategy to associate 18 caricatured faces, names, and additional facts. On all immediate tests (prompted by the faces), and on the delayed tests of Experiments 2a and 2b combined, mnemonic students statistically outperformed control students on name and political affiliation identification measures as well as on name-affiliation pairs. Interference issues were examined in the latter 2 experiments. The study findings replicate prior positive findings with the face-name mnemonic and demonstrate that additional factual information can be successfully added to the face-name mnemonic strategy through implementation of the present mnemonic format.     

Acute effects of static stretching on characteristics of the isokinetic angle – torque relationship,surface electromyography,and mechanomyography

Abstract

The aims of this study were to examine the acute effects of static stretching on peak torque, work, the joint angle at peak torque, acceleration time, isokinetic range of motion, mechanomyographic amplitude, and electromyographic amplitude of the rectus femoris during maximal concentric isokinetic leg extensions at 1.04 and 5.23 rad · s^?1 in men and women. Ten women (mean ± s: age 23.0 ± 2.9 years, stature 1.61 ± 0.12 m, mass 63.3 ± 9.9 kg) and eight men (age 21.4 ± 3.0 years, stature 1.83 ± 0.11 m, mass 83.1 ± 15.2 kg) performed maximal voluntary concentric isokinetic leg extensions at 1.04 and 5.23 rad · s^?1. Following the initial isokinetic tests, the dominant leg extensors were stretched using four static stretching exercises. After the stretching, the isokinetic tests were repeated. Peak torque, acceleration time, and electromyographic amplitude decreased (P≤ 0.05) from pre- to post-stretching at 1.04 and 5.23 rad · s^?1; there were no changes (P > 0.05) in work, joint angle at peak torque, isokinetic range of motion, or mechanomyographic amplitude. These findings indicate no stretching-related changes in the area under the angle – torque curve (work), but a significant decrease in peak torque, which suggests that static stretching may cause a “flattening” of the angle – torque curve that reduces peak strength but allows for greater force production at other joint angles. These findings, in conjunction with the increased limb acceleration rates (decreased acceleration time) observed in the present study, provide tentative support for the hypothesis that static stretching alters the angle – torque relationship and/or sarcomere shortening velocity.     

千禧一代,“自恋狂”还是“新人王”?

我即将要做的事正是多少年来老一辈的人都曾经做过的:批评比我年轻的人懒惰、自私、浅薄、自以为是。以下是一些冰冷的硬数据:美国国家卫生研究院提供的数据显示,与目前达到65岁或以上的人相比,二十多岁的年轻人患自恋型人格障碍的几率是前者的将近三倍。这些人深信自己很了不起:全国青年与宗教调查报告发现,60%的千禧一代表示,他们在任何情况下遵守的道德是:他们觉得这是对的就行。     

The impact of PL 94-142 on the practice of school psychology: A national survey

This paper presents the results of a national survey of school psychologists to determine the impact of PL 94-142 on the role of the school psychologist. Data were based on responses to 856 surveys by practicing school psychologists who were selected randomly from the NASP membership list during 1979-80. The results suggested that this legislation has had remarkably little impact on the evaluation procedures used or on the school psychologist's role. The two clear changes that have occurred may have negative implications for psychological services (e.g., an increased focus on handicapped children and increased paperwork). It was found that many school psychologists are involved in evaluation, but do not have time to be involved in the IEP process, or to provide follow-up consultation, or direct intervention for prevention and/or therapeutic purposes. This problem was exacerbated in districts that had ratios of greater than 1,000 to 1. Despite these problems, many respondents view the legislation in positive terms, and feel it has helped to enlarge the scope of practice.     

HIGHER EDUCATION FOR THE SECOND HALF OF LIFE: THE STATE OF THE ART AND FUTURE PERSPECTIVES

This paper offers some aims for education at the university level for middle‐age and older adults. A review of the scope of knowledge and practice in this field is presented along with a brief analysis of some factors leading to the growing interest in this area, in which a lack of empirical knowledge and clear philosophy is evident. Research findings from life‐span developmental studies on the cognitive, personality, and motivational characteristics of older people are discussed in terms of their implications for higher education. In the light of these considerations, suggestions for planning academic programs for older adults are presented. Academic programs must be rooted in curricula that concurrently foster age integration at the university while attending to the special needs of middle‐age and older adults. Academic programs require programs of action research and training for educators and students of adult development. This is seen as essential to promote future progress in this area.     

Scientific explanations and piagetian operational levels

Explaining natural phenomena is an important goal in science teaching. A logical analysis reveals that causal explanations exhibit formal operational structures in that they consist of implication statements chained together through transitive reasoning. It was hypothesized in the present study that individuals who do not reason formally will have difficulty in learning explanations presented in instruction. To test this hypothesis, the effect of levels of operational thought on the explanations which ninth-grade (n = 26) and college (n = 40) physical science students reconstructed after instruction was investigated. Subjects in the study were classified through Piagetian tests as concrete or formal operational. Both concrete and formal subjects were successful in recalling explanations requiring the chaining of two implication statements. Formal operational subjects performed significantly better than concrete operational subjects in three of the four tests of the reconstruction of complex explanations requiring the chaining of six implication statements. In teaching complex causal explanations to students at the concrete operational level, it is suggested that teachers be prepared to furnish some external structuring which the students can rely on in logically relating the various propositions of the explanation to one another.
