This study addresses how the temperament characteristics of seven year old learning disabled students are viewed in relation to those of the normally achieving students. Teacher perceptions, parent perceptions, and teacher versus parent perceptions are examined utilizing the six dimensions (activity, adaptability, approach/withdrawal, intensity, distractibility, and persistence) and the three factors (emotionality, sociability, and persistence) of the Temperament Assessment Battery.

The United Kingdom Equality Act of 2010 poses challenges to regulators, educators, and employers to ensure that disabled people are not excluded from health care professions on the basis of their impairment. Professional bodies must also anticipate the needs of disabled people and facilitate inclusion. In this article, we discuss some of the current tensions that exist between U.K. antidiscrimination legislation and the professional and statutory regulatory bodies that govern registration of health and social care practitioners in the United Kingdom. We present research that used a mixed methods approach to explore the tensions between higher education and placement providers in the health sector. Disabled students and health professionals engaged in semistructured interviews, and a survey explored the knowledge, skills, and attitudes of professional staff from a range of disciplines and institutions. Findings suggest that the negative feelings disabled students report are also evident in responses from health care professionals. Notions of risk emerge as a key issue from the data. We discuss whether the risk is perceived or actual and develop models to challenge existing preconceptions about the risk posed by disabled students when training as health care professionals. Finally, we suggest that while work clearly needs to be done in this area, some of this work can be addressed through the development of an inclusive curriculum for all health care practitioners. This article proposes an educational model of risk with which to guide this process.

Objectives: (1) To ascertain whether adult siblings of disabled individuals are more prone to anxiety and depression symptomatology than a closely matched control group. (2) To examine the contribution that perceived parenting styles, attachment styles and personality traits play in the long-term affective outcome of these siblings. (3) To consider if the type of disability has a role in sibling affective outcome. Design: A cross-sectional, closely matched study design, with data collected through self-report. One-way ANOVAs, correlational analyses, moderation and mediation analyses were applied. Participants: Adult siblings of disabled individuals (SDI), were initially contacted through support groups, such as SIBS, the Down’s Syndrome Association, the National Autistic Society and the Prader-Willi Association (UK) and responded to a postal or e-mailed questionnaire; 150 participants returned the completed questionnaire. The 150 control group participants were closely matched on the variables of gender, age, marital status and when possible socio-economic status, in order to compare like with like. This group was contacted through friends, family, work colleagues and local businesses. Measures: All the participants completed a range of demographic questions; the SDI were additionally asked questions regarding their disabled sibling. The established measures used included the Hospital and Anxiety Depression Scale (Zigmond & Snaith, 1983), Experiences in Close Relationships (Brennan, Clark & Shaver, 1998), an adapted measure of the Descriptions of Parental Caregiving Style (DPCS, Hazan & Shaver, 1986) and the International Personality Item Pool (Goldberg, 1999). Results: The majority of SDI reported no increased anxiety or depression symptomatology, however, when compared the SDI did report higher levels of anxiety and depression symptomatology than the control group; also higher levels of perceived inconsistent mothering, attachment-related anxiety and neuroticism, with lower levels of extraversion than the control group. These variables mediated the path between having a disabled sibling and anxiety and depression, with the notable exception of perceived inconsistent mothering. This variable showed no association with any of the established measures for the SDI group; however, there were associations consistent with previous research for the control group. There was no moderation effect on anxiety or depression between the demographic variables and SDI. The autistic spectrum disorder siblings reported similar levels of anxiety symptomatology to Prader-Willi siblings but higher than Down’s syndrome siblings and the control group and they also reported the highest levels of depression symptomatology. Conclusions: The adult SDI’s higher propensity towards anxiety and depression is a cause for concern; particularly when explained through heightened levels of attachment-related anxiety, high levels of neuroticism and low levels of extraversion. The lack of association with perceived inconsistent mothering requires further investigation. These results can help guide interventions or clinical therapies; the emotional well-being of SDI is paramount as they will possibly be among the first group to assume responsibility for their disabled siblings.

The fractionation of zircons by sedimentary processes into continental margin sandstone deposits results in a biased preservation of pre-existing continental crust in the form of zircon in those sequences. This provides a unique opportunity to distinguish between the contrasting theories of episodic growth versus constant volume of continental crust over geologic time through Hf isotope ratios of detrital zircons. ¹⁷⁶Hf/¹⁷⁷Hf ratios were determined for detrital zircon fractions from 2.6-3.0 Ga old sedimentary sequences from the Canadian Shield, North Atlantic, Wyoming, and Kaapvaal Cratons. Hf T(CHUR) ages are less than 3.0 Ga and ε(Hf) values are positive or slightly negative at the time of deposition for most of the Malene, Canadian Shield, Wyoming and upper portions of the Kaapvaal sediments. Notable exceptions are basal samples of the Pongola (3.32 Ga), Dominion (3.11 Ga) and Witwatersrand (3.13 Ga), an arkose from Michigan (3.20 Ga) and one Malene sample (2.97 Ga), all of which either unconformably overlie or are closely associated with pre-3.0 Ga crust. Nd data for shales from the same sequences in the Canadian Shield and Kaapvaal sequences mimic the Hf results. The late Archean sequences appear to be dominated by zircon populations of late Archean age. Hf model ages, from pre-3.0 Ga strata (Upernavik of Labrador and quartzites from Montana), range from 3.1 to 3.6 Ga and are broadly consistent with ages of coexisting volcanics or intrusives, suggesting little inheritance of significantly older material. 2.0-2.5 Ga old quartzites from the Canadian Shield, Wyoming and South Africa have 2.58 to 2.84 Ga model Hf ages indicative of a large expanse of late Archean crust exposed at the time of deposition. The data strongly suggest inheritance of pre-3.0 Ga zircons only in areas where pre-3.0 Ga old crust exists today, and imply that the quantity of continental crust prior to 3.0 Ga ago was not much greater in extent than the pre-3.0 Ga crust exposed today. Small amounts of continental crust prior to 3.0 Ga ago and rapid addition of continental crust between 2.5 and 3.0 Ga ago are consistent with the episodic growth theory of crustal evolution.
