Village Elders’ and Secondary School Students’ Explanations of Natural Phenomena in Papua New Guinea

This research investigated the sources of explanations and understanding of natural phenomena in terms of the students’ cultural and school science experiences. The first phase involved interviews with eight village elders that probed their explanations and understanding of natural phenomena. The second phase involved the design, development and administration of two questionnaires on natural phenomena to 179 students in a rural boarding high school in Papua New Guinea (PNG). Most village elders gave explanations of many of the phenomena in terms of spirits, spells, magic, religion, and personal experiences. Most school-aged students choose scientific explanations of natural phenomena in terms of what they had learned in school or from personal experiences. However, many choose explanations of the same phenomena about spirits, spells and magic that came from the village, family or home. The study revealed that students’ ideas about natural phenomena are strongly governed and controlled by their school science knowledge in the school setting. It is likely that their own traditional knowledge cannot be identified in a school setting but that questionnaires in the students’ local language be given to students in their villages (as opposed to school). In addition, so as not to diminish the value of this traditional knowledge, science education programs are needed that are able to consider and harmonise traditional knowledge with school science.     

Intellectual Disability and Developmental Risk: Promoting Intervention to Improve Child and Family Well‐Being

Initial intervention processes for children with intellectual disabilities (IDs) largely focused on direct efforts to impact core cognitive and academic deficits associated with the diagnosis. Recent research on risk processes in families of children with ID, however, has influenced new developmental system approaches to early intervention. Recent risk and resilience processes are reviewed that connect stress, family process, and the high rates of behavioral problems in children with ID that have substantial influence on child and family outcomes. These models are linked to emerging evidence‐based intervention processes that focus on strategic parent skill training and mindfulness interventions that reduce parental stress and create indirect benefits for children's behavioral competencies. A family‐focused developmental systems approach (M. J. Guralnick, 2011) is emphasized.     

User library service expectations in health science vs. other settings: a LibQUAL+ Study

Objectives: To explore how the library service expectations and perceptions of users might differ across health‐related libraries as against major research libraries not operating in a medical context; to determine whether users of medical libraries demand better library service quality, because the inability of users to access needed literature promptly may lead to a patient who cannot be properly diagnosed, or a diagnosis that cannot be properly treated. Methodology: We compared LibQUAL+® total and subscale scores across three groups of US, Canadian and British libraries for this purpose. Results: Anticipated differences in expectations for health as other library settings did not emerge. Conclusions: The expectations and perceptions are similar across different types of health science library settings, hospital and academic, and across other general research libraries.     

Women professors and the academic housework trap

Women constitute just over one fifth of full professors in UK higher education and whilst work has emerged in recent years on professors as leaders, there has been comparatively little research about how this under-represented cadre define and practise their role as intellectual leaders. This paper seeks to analyse how women see their role as full professors through autobiographical accounts of their intellectual and career histories via interviews with women professors, and a small comparison group of male professors. A range of freedoms and responsibilities connected with the professorial role are identified along with personal qualities considered central to success. Both female and male professors understand their role principally in terms of research leadership, but women are more likely to emphasise the importance of academic citizenship, especially mentoring, compared to their male counterparts, an obligation that weighs especially heavily on women working in science, technology, engineering and mathematics areas. While these findings are indicative of the continuing effect of so-called ‘academic housework’ in holding back the academic careers of women, they are also a positive indicator of a commitment to an all-round role as an intellectual leader.     

The relationship between perceived ageism and depressive symptoms in later life: Understanding the mediating effects of self-perception of aging and purpose in life,using structural equation modeling

The purpose of this study is to examine the relationship between perceived ageism and depression in later life and to clarify the mechanism underlying this relationship by examining the mediating effects of self-perception of aging and purpose in life. The Health and Retirement Study surveys were used for this secondary analysis of data. The sample included 3,991 older adults, and structural equation modeling (SEM) analyses using structural regression models were conducted. SEM analyses revealed that full mediation effects of self-perception of aging and purpose in life exist. Older adults who perceive ageism are likely to have negative self-perception of aging, and this negative view of their own aging is likely to decrease purpose in life and increase depressive symptoms. The results of this study imply that more efforts and resources are necessary to reduce ageism and its negative effect on depression among older adults. Additionally, the current study suggests the necessity of anti-ageism policies and social services. Increasing positive self-perception of aging, purpose in life, and resilience could be the key to a better quality of life for older adults.     

Laboratory versus field testing in cricket bowling: a review of current and past practice in modelling techniques

In cricket bowling, the reconstruction of elbow angle data is of utmost importance to the bowling versus throwing argument. This paper reviews system and modelling errors inherent in three-dimensional reconstruction processes with respect to the elbow extension tolerance set by the International Cricket Council. An understanding of these factors will enable more informed decisions about the choice of in-field versus laboratory testing in the calculation of elbow extension during bowling in cricket. Although there is a paucity of objective data related to in-field and laboratory testing, biomechanists must be guided by the greater accuracy of opto-reflective than video-based systems and so testing, at least for the present, should be conducted in a laboratory setting.     

Factors contributing to preservice teachers' management of children's problem behaviors

The purpose of this study was to assess factors that contribute to preservice teachers' choice of a helping or a restrictive strategy to manage social immaturity and social defiance behaviors among children. Levels of tolerance, opinions as to the causes of behavior, perceptions of adverse effects or costs of problem behaviors, and choice of strategy were measured in response to hypothetical samples of problem behavior. Regression analyses indicated that the costs of problem behavior significantly predicted the type of strategy that would be chosen. Training preservice teachers to manage these costs was the main implication for teacher training programs.     

Rate of conceptual development among deaf preschool and primary children as compared to a matched group of nonhearing impaired children

Seventeen deaf children and a matched group of 17 nonhearing impaired children were assessed to compare rate of basic concept development. The results indicate that deaf children scored approximately two standard deviations below their matched nonhearing impaired peers. Additionally, the deaf children exhibited a relatively flat subtest proffle, suggesting that basic concepts that have not been specifically taught remain uniformly delayed for deaf children.
