An Analysis of Intrinsicality

The leading account of intrinsicality over the last thirty years has arguably been David Lewis's account in terms of perfect naturalness. Lewis's account, however, has three serious problems: i) it cannot allow necessarily coextensive properties to differ in whether they are intrinsic; ii) it falsely classifies non‐qualitative properties like being Obama as non‐intrinsic; and iii) it is incompatible with a number of metaphysical theories that posit irreducibly non‐categorical properties. I argue that, as a result of these problems, Lewis's account should be rejected and replaced with an alternative account, which also analyses intrinsicality in terms of perfect naturalness, but which avoids these problems.     

Effects of Weight Cue Reactivity on Self-Report Measures of Body Dissatisfaction

Research has shown that answers on self-report measures can be influenced by a participant’s awareness of information regarding the study (“reactivity”). There exists a gap in the literature regarding weight cue reactivity on self-report measures of body dissatisfaction (BD). This type of reactivity involves exposing participants to information regarding their height, weight, or body mass index (BMI). Ninety-Nine participants (45.5 % female, mean age = 20.17, SD = 3.08) were randomly assigned to one of three conditions: proximal weight cue (being weighed before completing measures); distal weight cue (knowledge of impending measurement following questionnaire completion); and no weight cues (control), all before measures of BD. Perceived body size and BD were measured using the Stunkard Figure Rating Scale. Two separate ANCOVAs revealed a significant main effect for condition on self-reported perceived body size F [2,92] = 5.22, p = 0.01, η2 = 0.10, as well as on BD, F [2,92] = 9.46, p < 0.001, η2 = 0.17, while controlling for BMI. Both proximal and distal cues elicited elevated BD; only proximal cues elicited self-reported perceived body size. These results quantify the impact of weight cue reactivity effects on self-report measures and suggest that researchers and/or clinicians collect answers on such measures prior to anthropometric data.

Spatial cognition: evidence from visual neglect

Recent work on human attention and representational systems has benefited from a growing interplay between research on normal attention and neuropsychological disorders such as visual neglect. Research over the past 30 years has convincingly shown that, far from being a unitary condition, neglect is a protean disorder whose symptoms can selectively affect different sensory modalities, cognitive processes, spatial domains and coordinate systems. These clinical findings, together with those of functional neuroimaging, have increased knowledge about the anatomical and functional architecture of normal subsystems involved in spatial cognition. We provide a selective overview of how recent investigations of visual neglect are beginning to elucidate the underlying structure of spatial processes and mental representations.     

Evidence for altered Fragile-X mental retardation protein expression in response to behavioral stimulation

The Fragile-X mental retardation protein, the protein absent in Fragile-X syndrome, is synthesized near synapses upon neurotransmitter activation. Humans and mice lacking this protein exhibit abnormal dendritic spine lengths and numbers. Here we investigated Fragile-X protein levels in animals exposed to behavioral paradigms that induce neuronal morphological change. Fragile-X protein immunoreactivity was examined in visual cortices of rats reared in a complex environment for 10 or 20 days, motor cortices of rats trained on motor-skill tasks for 3 or 7 days, and either visual or motor cortices of inactive controls. Rats exposed to a complex environment for 20 days or trained for 7 days on motor-skill tasks exhibited increased Fragile-X protein immunoreactivity in visual or motor cortices, respectively. These results provide the first evidence for a behaviorally induced alteration of Fragile-X protein expression and are compatible with previous findings suggesting synaptic regulation of its expression. These results also strengthen the association of Fragile-X mental retardation protein expression with the alteration of synaptic structure.     

Using Intergroup Contact Theory to Reduce Stigma Against Transgender Individuals: Impact of a Transgender Speaker Panel Presentation

Sexual minorities experience significant stigma and prejudice. Much research has examined sexual stigma and prejudice impacting gay and lesbian individuals, but limited research has examined other sexual minorities, such as transgender persons or individuals whose gender identity or expression is incongruent with their assigned gender or anatomical sex. Research has found that interpersonal contact with sexual minorities is associated with lower sexual stigma and prejudice. Intergroup contact theory predicts that interaction between groups can reduce stereotyping and improve intergroup relationships. Using a randomized crossover design, this study compared the impact of exposure to a transgender speaker panel vs. a traditional transgender lecture presentation on transphobia. Results indicated greater immediate reductions of transphobia following the transgender speaker panel than traditional lecture.     

The Evolution and Treatment of Korsakoff's Syndrome

Wernicke's Encephalopathy is an acute neuro-psychiatric condition caused by an insufficient supply of thiamine (Vitamin B1) to the brain. If undiagnosed or inadequately treated, it is likely to proceed to Korsakoff's Syndrome. Wernicke's Encephalopathy can result from dietary deficiency alone and this form is usually successfully treated, with little chance of Korsakoff's Syndrome supervening. On the other hand, thiamine deficiency associated with alcohol misuse/dependence may require up to 1 gram of thiamine IV in the first 24 hours to be treated successfully. The reasons for this difference in treatment will be discussed. Thiamine diphosphate acts as a co-factor for a number of thiamine-dependent enzymes. Thiamine deficiency leads to a reduction in the activity of these enzymes, and this leads to alterations in mitochondrial activity, impairment of oxidative metabolism, decreased energy status and eventually selective neuronal death. The damage caused by the combination of thiamine deficiency and alcohol metabolism probably interferes with adequate thiamine transport at a number of sites in the body, including the blood-brain barrier, as well as causing damage to the apoenzymes which then require higher concentrations of thiamine to work normally. The accumulated damage is likely to render the use of oral thiamine therapeutically inadequate since the body is unable to produce high enough concentrations of thiamine in the blood to traverse the blood-brain barrier. Some individuals are probably genetically predisposed to develop Wernicke's. Long before individuals with alcohol misuse or dependence develop Wernicke's Encephalopathy the neurons and other cells of the body are functioning sub-optimally because of the inadequate supply of thiamine and the neurotoxic effect of alcohol. This relative deficiency initiates a series of pathological changes which accumulate and further interfere with the supply of thiamine and its utilisation at a time when the requirements are increased. The best treatment for Korsakoff's Syndrome is timely recognition of Wernicke's Encephalopathy and appropriate intervention and prevention.     

Attachment and amae in Japanese romantic relationships

Amae is a Japanese term that refers to an individual's inappropriate behaviour when he/she presumes indulgence from a significant other. The link between attachment style and amae has been debated, but few studies have examined this link empirically. This study examined the association of attachment style with amae behaviour in Japanese dating couples over a two‐week period. Results showed that for Japanese men, anxious attachment was positively associated with their amae behaviour, and in turn, with their increased relationship quality. Conversely, avoidant attachment was negatively associated with their amae behaviour, and in turn, with their decreased relationship quality.     

Selling and Sales Management in Action: The Role of Strategic Selling in the Company Turnaround Process

Despite the importance of marketing orientation to company profile and performance as presented in the literature, there has been little attention paid to the role of strategic selling in the company turnaround process in published studies. This article explores selling's contribution to company turnaround through a study of ailing and rejuvenated companies in the mature engineering industry. The development and implementation of sales strategies in successfully turned around and failed companies are compared. The role of strategic selling is broadened as new concepts are developed and explored.
