Environmental and Genetic Variance in Children's Observed and Reported Maladaptive Behavior

The genetic and environmental contributions to children's maladaptive behavior are assessed in a sample of 154 twin pairs (77 MZ twin pairs and 77 DZ twin pairs), who range in age from 6 to 11 years. To bridge the strengths of behavioral genetic methods and environmental assessment techniques, we use a multimethod, multimeasure approach to data collection, and analyze the data using behavioral genetic modeling techniques. Results indicate that genetic variation accounts for a majority of the variance in parent-reported child maladaptive behavior (average = 62%). One parent-report measure also suggests a smaller, significant contribution of shared environmental variance. In contrast to the parental ratings, the observational coding and global impressions of parent-twin interactive behavior suggest that shared environment is the primary source of variance accounting for parent and child maladaptive behavior. This is due, in part, to the direct influence one's interactive partner has on the expression of maladaptive behavior in an interactive setting. When controlling for the co-participant's behavior, genetic variation increases and shared environmental variation decreases.     

Embracing the complexity of inclusive science classrooms: Professional development through collaboration

There are no panaceas and no shortcuts. Man is an amphibious being who lives simultaneously or successively in several universes: in the world of matter, the world of mind, the world of spirit; in the individual world and in the social world; in the homemade universe of his own artifacts, institutions, and imaginings, and in the given, the God-made universe of nature and grace. In the very nature of things none of the major problems confronting such a being can possibly be a simple problem. Those who seek simple solutions for complex problems may have the best of intentions; but unfortunately there is an original sin of the intellect in our habit of arbitrary oversimplification. Those who act without taking precautions against this vice of their intellectual nature doom themselves and their fellows to perpetual disappointment. (Aldous Huxley, 1953, p. 1.)     

Child Effects on Parental Negativity: The Role of Heritable and Prenatal Factors

This study examined two possible mechanisms, evocative gene–environment correlation and prenatal factors, in accounting for child effects on parental negativity. Participants included 561 children adopted at birth, and their adoptive parents and birth parents within a prospective longitudinal adoption study. Findings indicated child effects on parental negativity, such that toddlers’ negative reactivity at 18 months was positively associated with adoptive parents’ over-reactive and hostile parenting at 27 months. Furthermore, we found that child effects on parental negativity were partially due to heritable (e.g., birth mother [BM] internalizing problems and substance use) and prenatal factors (e.g., BM illicit drug use during pregnancy) that influence children’s negative reactivity at 18 months. This study provides critical evidence for “child on parent” effects.     

Does spatial awareness training affect anatomy learning in medical students?

Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.     

Storytelling: The Real Work of Museums

Abstract This article examines the ways in which the narrative or story form generates personal connections between visitors and content and thus is ideally suited to the work of museums. Starting with a review of the qualities of narrative, the article provides specific examples of how stories and storytelling have worked in exhibitions, public programs and outreach to schools.     

Museums and Indigenous People in Australia: A Review of Previous Possessions,New Obligations: Policies for Museums in Australia and Aboriginal and Torres Strait Islander Peoples

Previous Possessions, New Obligations was launched by Museums Australia Inc. in 1993, the International Year for the World's Indigenous People, as a policy framework to guide the development of relationships between museums in Australia and Indigenous Australians. The policy was based on consultation with Indigenous people to develop protocols, policies and procedures for more sensitive collection management and for including Indigenous people in research and public programs; and to address issues of governance. It expressed the values that would underpin new relationships between museums in Australia and Indigenous Australians. An evaluation of the policy was conducted in 2000 in a collaboration between the Australian Museum Audience Research Centre, Sydney, and Museums Australia Inc., Canberra. The evaluation found that the policy had substantially met its goals, particularly in establishing the primary rights of Indigenous people to control their cultural material in museum collections. However, a range of substantially new issues emerged which require new policy responses and initiatives.     

Using laser Doppler vibrometry to measure capillary surface waves on fluid-fluid interfaces

Capillary wave phenomena are challenging to study, especially for microfluidics where the wavelengths are short, the frequencies are high, and the frequency distribution is rarely confined to a narrow range, let alone a single frequency. Those that have been studying Faraday capillary waves generated by vertical oscillation have chosen to work at larger scales and at low frequencies as a solution to this problem, trading simplicity in measurement for issues with gravity, boundary conditions, and the fidelity of the subharmonic capillary wave motion. Laser Doppler vibrometry using a Mach–Zehnder interferometer is an attractive alternative: The interface’s motion can be characterized at frequencies up to 40 MHz and displacements of as little as a few tens of picometers.

Psychological traits and loyalty intentions towards e-Government services

Purpose

Having been rated the world's leader in e-Government Readiness in 2002, 2004, and 2005, Taiwan sought to capitalize on its experience in e-Government implementation by launching, in 2007, a new Government-to-Citizen service entitled “e-Housekeeper”. The success of this service has since then become an important focus for practitioners.

Methodology

The reported research utilizes a psychological approach that is different from the classical models that dominate the existing literature, by examining how citizens’ adaptive–innovative cognitive styles and involvement jointly influence their loyalty intentions towards e-Housekeeper. The style/involvement model is tested by means of information from a sample of 206 Taiwan citizens.

Findings

While innovators initiated e-Housekeeper significantly earlier than others, their usage did not last for long. In contrast, more-involved citizens have shown higher loyalty intentions. More specifically, a combination of decision-making style and involvement significantly influences both when citizens try the service and whether they continue to use it: more-involved adaptors reported the strongest loyalty intentions.

Originality/value

Practical implications of the findings for the style/involvement model are suggested in the context of enhancing the strategic performance of e-Government services. The value of the style/involvement model is enhanced as a social scientific approach to the analysis of consumer innovation.
