The Divorce Process and Child Adaptation Trajectory Typology (DPCATT) Model: The Shaping Role of Predivorce and Postdivorce Interparental Conflict

Divorce has been conceptualized as a process. Research has extensively demonstrated that it is pre/postdivorce family environment factors that primarily account for the variability in children’s adaptation over parental divorce process rather than the legal divorce per se. Amongst various factors, interparental conflict has been consistently identified as a prominent one. Surprisingly, a single source is still lacking that comprehensively synthesizes the extant findings. This review fills this gap by integrating the numerous findings across studies into a more coherent Divorce Process and Child Adaptation Trajectory Typology (DPCATT) Model to illustrate that pre/postdivorce interparental conflict plays crucial roles in shaping child adaptation trajectories across parental divorce process. This review also summarizes the mechanisms (e.g., child cognitive and emotional processes, coparenting, parent–child relations) via which pre/postdivorce interparental conflict determines these trajectories and the factors (e.g., child gender and age, child coping, grandparental support) that interact with pre/postdivorce interparental conflict to further complicate these trajectories. In addition, echoing the call of moving beyond the monolithic conceptualization of pre/postdivorce interparental conflict, we also review studies on the differential implications of different aspects (e.g., frequency versus intensity) and types (e.g., overt versus covert) of interparental conflict for child adjustment. Last, limitations of prior studies and avenues for future research are discussed. The proposed framework may serve as a common knowledge base for researchers to compare/interpret results, detect cutting edges of the fields, and design new studies. The specificity, complexity, nuance, and diversity inherent within our proposed model await to be more fully revealed.

     

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.     

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.     

Acceptance-Enhanced Behavior Therapy for Trichotillomania in Adolescents

Although several studies have examined the efficacy of Acceptance Enhanced Behavior Therapy (AEBT) for the treatment of trichotillomania (TTM) in adults, data are limited with respect to the treatment of adolescents. Our case series illustrates the use of AEBT for TTM in the treatment of two adolescents. The AEBT protocol (Woods & Twohig, 2008) is a structured treatment manual that was adapted to the individual clients’ needs and clinical progress. Both clients reported clinically significant gains in treatment as determined by at least 2 weeks of abstinence from pulling, and subjective reports of decreased distress and impairment, although one required a booster session due to relapse. AEBT is worth further exploration as a treatment for adolescents with TTM.     

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.     

How the Performance of Mentoring Activities Affects the Mentor's Job Outcomes

Peer mentoring occurs in a sales force when a more experienced salesperson (mentor) takes responsibility for the development and guidance of a less experienced salesperson (protégé). Few studies have examined how this work relationship affects the mentor. This study explores the relationships between the mentoring activities performed by the mentor and the benefits that are achieved for the mentor. Data was collected from real estate salespeople who indicated they were serving as mentors. The exploratory findings demonstrate that the different activities performed by a mentor could affect the benefits received by the mentor. For example, providing a protégé with exposure to others in the organization rejuvenates the mentor's career and improves some aspects of the mentor's satisfaction. Helping the protégé with his or her selling skills has a positive impact on several aspects of the mentor's own performance. Results help explain why an experienced salesperson might choose to mentor.     

Diagnosis of Personality Disorders: A Case Study

In this article, I report a case highlighting diagnostic uncertainty about psychopathology on both Axes I and II. It concerns in part the problem of comorbidity in relation to diagnostic classification of Axis II personality disorders. After commenting on these uncertainties in relation to categorical and dimensional models, I also consider a psychoanalytic explanation to illustrate an example in which a theoretical model informs diagnostic interviewing. I emphasize how the clinical information that unfolds from an interview based on this theoretical model generates inferences about psychopathology that extend clinical understanding beyond the formal diagnostic assessment of Axes I and II disorders and assessment by self-report.
