Liberal Democracy and the Inferior 'Other'Other’: Could the peace liberal democracy promises to bring not extend to ‘Others’?

Advocates of liberal democracy argue that its principles and practices contribute directly to peace (at both inter-state and domestic levels). They rely on ideals such as the rule of law, institutional checks and balances on power, an ethos of tolerance, and free market economics to deliver the liberal peace. Liberals, however, overlook three important features embedded in the construction of liberal democracy which can serve to facilitate political violence: 1) the fixed and thus non-negotiable nature of liberal democracy’s core principles, 2) the inferior manner in which it conceives ‘Other’ social orders that do not share its core principles, and 3) the urge to proselytise Others. Together, these constitutive qualities can facilitate moves by leaders of Other groups to argue that liberal democracy threatens ‘their’ preferred identity, and thus its promised peaceful outcomes can be put in doubt.

Responding to interpersonal and physically provoking situations in classrooms: emotional intensity in children with attention deficit hyperactivity disorder

The present research investigated the emotional functioning of children with and without Attention Deficit Hyperactivity Disorder (ADHD), in order to examine the relationships between emotional intensity and classroom-based responses to physically and interpersonally provoking situations. Seventy children (35 with ADHD and 35 without ADHD) in Years 3–8 participated and were matched on age, gender, grade, and school class. Each child was observed individually in the classroom over two 20-min periods. The Responses to Interpersonal and Physically Provoking Situations Observation Schedule was used to record the frequency and severity of responses and the triggers for these during the observational periods. Children later rated their emotional intensity in response to hypothetical scenarios on the Emotional Intensity Scale for Children. Results revealed children with ADHD displayed significantly more frequent and severe challenging and solitary off-task behaviours, and significantly more frequent vocalisations and severe interactional off-task behaviours. For triggers, environmental and teacher-initiated distractions were significantly more frequently observed in children with ADHD. There were no differences in ratings of emotional intensity between children with and without ADHD, although a number of significant and meaningful correlations were observed between positive emotional intensity scores and responses and triggers.

Are community newspapers really different?

Cafarella has written what amounts to a wake-up call for many journalism educators. Her paper will have varying degrees of relevance for different educators and different institutions. In some instances, she may well be reflecting the viewpoints of particular educators in particular situations but these same educators, because of institutional pressures and the very pressures of time and limited resources that Cafarella discusses in a suburban newspaper setting, are unable to implement their heart’s desire. For example, they may want to do all the things Cafarella cited, but to meet the academic requirements of their institution as opposed to the training needs of their students they must achieve a balance between the practical and the theoretical, between their own teaching and research performance, and they must be able to cope with the marking load they generate by creating endless practical assignments. Shorthand bobs up in Cafarella’s paper as a hurdle the graduate cadet must clear before being elevated to the status of graded journalist after the one-year cadetship, and I am reminded that arguments about the inclusion of shorthand in tertiary journalism courses has been debated at national and institutional levels for the past quarter of a century. In fact, shorthand is a kind of shorthand for this practice versus theory debate.

Pyramidal neurones in macaque visual cortex: Interareal phenotypic variation of dendritic branching patterns

The basal dendritic arbors of over 500-layer III pyramidal neurones of the macaque cortex were compared by fractal analyses, which provides a measure of the space filling (or branching pattern) of dendritic arbors. Fractal values (D) of individual cells were compared between the cytochrome oxidase (CO)-rich blobs and CO-poor interblobs, of middle and upper layer III, and between sublaminae, in the primary visual area (Vi). These data were compared with those in the CO compartments in the second visual area (V2), and seven other extrastriate cortical areas. (V4, MT, LIP, 7a, TEO, TE and STP). There were significant differences in the fractal dimensions, and therefore the dendritic branching patterns, of cells in striate and extrastriate areas. Of the 55 possible pairwise comparisons of fractal dimension of neurones in different cortical areas (or CO compartments), 39 proved to be significantly different. The markedly different morphologies of pyramidal cells in the different cortical areas may be one of the features that determine the functional signatures of these cells by influencing the number of inputs received by, and propagation of potentials through, their dendritic arbors.

The English-only movement: A communication analysis of changing perceptions of language vitality

This paper reexamines the potential impact of the English-only movement on linguistic minorities and Anglos' perceptions of their own and minority groups' language vitality. Of particular interest is the Hispanic population-the fastest growing minority in the U.S. Communication scholars have paid only scant attention to the English-only movement and how it affects the social and communication climate for Latinos. However, literature reviews prepared for the American Psychological Association and for the Teachers of English to Speakers of Other Languages (in 1991 and 1995, respectively) concluded that English-only initiatives have negative consequences for limited-English proficiency groups. Revisiting this still-growing issue in the light of more recent studies across disciplines and media reports, we examine how Anglo support for English-only policies limits the use, promotion, and salience of minority languages like Spanish in institutional settings and in the linguistic landscape and suggest directions for future research.

Mechanical effects on the skeleton: Are there clinical implications?

The basic morphology of the skeleton is determined genetically, but its final mass and architecture are modulated by adaptive mechanisms sensitive to mechanical factors. When subjected to loading, the ability of bones to resist fracture depends on their mass, material properties, geometry and tissue quality. The contribution of altered bone geometry to fracture risk is unappreciated by clinical assessment using absorptiometry because it fails to distinguish geometry and density. For example, for the same bone area and density, small increases in the diaphyseal radius effect a disproportionate influence on torsional strength of bone. Mechanical factors are clinically relevant because of their ability to influence growth, modeling and remodeling activities that can maximize, or maintain, the determinants of fracture resistance. Mechanical loads, greater than those habitually encountered by the skeleton, effect adaptations in cortical and cancellous bone, reduce the rate of bone turnover, and activate new bone formation on cortical and trabecular surfaces. In doing so, they increase bone strength by beneficial adaptations in the geometric dimensions and material properties of the tissue. There is no direct evidence to demonstrate anti-fracture efficacy for mechanical loading, but the geometric alterations engendered undoubtedly increase the structural properties of bone as an organ, increasing the resistance to fracture. Like all interventions, issues of safety also arise. Physical activities involving high strain rates, heavy lifting or impact loading may be detrimental to the joints, leading to osteoarthritis; may stimulate fatigue damage leading with some to stress fractures; or may interact pharmaceutical interventions to increase the rate of microdamage within cortical or trabecular bone.

A portable load cell for in-situ ore impact breakage testing

This paper discusses the design and characterisation of a short, and hence portable impact load cell for in-situ quantification of ore breakage properties under impact loading conditions. Much literature has been published in the past two decades about impact load cells for ore breakage testing. It has been conclusively shown that such machines yield significant quantitative energy-fragmentation information about industrial ores. However, documented load cells are all laboratory systems that are not adapted for in-situ testing due to their dimensions and operating requirements. The authors report on a new portable impact load cell designed specifically for in-situ testing. The load cell is 1.5 m in height and weighs 30 kg. Its physical and operating characteristics are detailed in the paper. This includes physical dimensions, calibration and signal deconvolution. Emphasis is placed on the deconvolution issue, which is significant for such a short load cell. Finally, it is conclusively shown that the short load cell is quantitatively as accurate as its larger laboratory analogues. (C) 2062 Elsevier Science B.V. All rights reserved.

Development of the HIV/AIDS stress scale

Development of a self-report measure of stress specific to HIV/AIDS is needed to advance our understanding of the role of stress in adaptation to HIV/AIDS: hence, the aim of this study was the development of the HIV/AIDS Stress Scale. A total of 132 homosexual/bisexual men with HIV/AIDS v ere interviewed and completed the HIV/AIDS Stress Scale and measures of coping strategies, appraisal, social support and adjustment (global distress, depression, social adjustment, number of HIV symptoms, and subjective health status) at three time points. Thirty-nine primary caregivers were interviewed and completed measures of stress and adjustment. Exploratory factor analyses of the HIV/AIDS Stress Scale items revealed three factors: Social, Instrumental and Emotional/Existential Stress. Factors had adequate internal reliabilities and were stable over 12 months. Construct validation data are consistent with recent stress/coping research that links higher levels of stress with more HIV symptoms. reliance on emotion-focused coping, lower social support, poorer levels of adjustment and higher levels of caregiver stress. Results extend this research by revealing new differential relations between various stress dimensions and stress/coping variables. Convergent validation data suggest that the HIV/AIDS Stress Scale shares conceptual similarity with threat appraisal. and differs from control liability and challenge appraisals. The HIV/AIDS Stress Scale shows potential for the elucidation of the role of stress in coping and adaptation to HIV/AIDS and disease progression in both research and clinical applications.
