Psychologists reflect on their sexual relationships with clients, supervisees, and students: Occurrence, impact, rationales, and collegial intervention

Practicing psychologists who engaged in prohibited sexual relationships with clients, supervisees, and students reflected on the impact, circumstances, and rationales associated with engaging in such relationships. Of thesample, 3.5% reported such relationships; 84% were male psychologists, and the majority of the relationships were with female clients after the therapist-client relationship ended. There was considerable variability in the evaluation of such relationships, with retrospective reflections being less positive. The majority of psychologists reported a significant impact on their professional work and identified personal vulnerabilities that contributed to developing such relationships. Collegial intervention was universally viewed as valuable. Professional implications are discussed.
Universal tree source coding using grammar-based compression

We apply so-called tree straight-line programs to the problem of universal source coding for binary trees. We derive an upper bound on the maximal pointwise redundancy (or worst-case redundancy) that improve previous bounds on the average case redundancy obtained by Zhang, Yang, and Kieffer using directed acyclic graphs. Using this, we obtain universal codes for new classes of tree sources.
Protein kinase D (PKD) activation in intact cells through a protein kinase C‐dependent signal transduction pathway.

Protein kinase D (PKD) is a serine/threonine protein kinase that is directly stimulated in vitro by phorbol esters and diacylglycerol in the presence of phospholipids. Here, we examine the regulation of PKD in living cells. Our results demonstrate that tumour‐promoting phorbol esters, membrane‐permeant diacylglycerol and serum growth factors rapidly induced PKD activation in immortalized cell lines (e.g. Swiss 3T3 and Rat‐1 cells), in secondary cultures of mouse embryo fibroblasts and in COS‐7 cells transiently transfected with a PKD expression construct. PKD activation was maintained during cell disruption and immunopurification and was associated with an electrophoretic mobility shift and enhanced 32P incorporation into the enzyme, but was reversed by treatment with alkaline phosphatase. PKD was activated, deactivated and reactivated in response to consecutive cycles of addition and removal of PDB. PKD activation was completely abrogated by exposure of the cells to the protein kinase C inhibitors GF I and Ro 31–8220. In contrast, these compounds did not inhibit PKD activity when added directly in vitro. Co‐transfection of PKD with constitutively activated mutants of PKCs showed that PKCepsilon and eta but not PKCzeta strongly induced PKD activation in COS‐7 cells. Thus, our results indicate that PKD is activated in living cells through a PKC‐dependent signal transduction pathway.
Full-Time Ability Grouping of Gifted Students

Positive socioemotional outcomes and developments represent important educational goals. Full-time ability grouping of gifted students has been criticized for potentially detrimental socioemotional effects. Therefore, in the present longitudinal study, we investigated whether or not social self-concepts and school-related attitudes and beliefs are affected by full-time ability grouping of the gifted. Students in regular classes and students in special classes for the gifted were paralleled for cognitive ability, sex, socioeconomic status, and school. By doing so, we studied 99 “statistical twins” (N = 198) from the beginning of fifth grade to the middle of sixth grade. Data were analyzed through repeated-measures multivariate analysis of covariance (within-subject factor: time; between-subject factors: class type—gifted vs. regular—and cognitive ability as covariate). Cognitive ability had hardly any effect on the variables under study. Attending a gifted class had initially positive effects on students’ social self-concept of acceptance but no effects on social self-concept of assertiveness. Moreover, children in gifted classes exhibited more interest in school and reported better student–teacher relationships than their counterparts in regular classes.
A Posterior Tibial Nerve Neurilemoma Unrecognized for 10 Years: Case Report

OBJECTIVE AND IMPORTANCE Neoplasms of peripheral nerves can be obscured, especially during the early phase. The author reports a patient with a posterior tibial nerve neurilemoma (schwannoma). For a decade, the tumor was misdiagnosed as nonspecific S1 radiculopathy and psychogenic chronic pain syndrome. The patient’s presentation and initial management are unique. CLINICAL PRESENTATION A 40-year-old woman reported severe left foot and calf pain, numbness, and weakness. The symptoms were evident during three pregnancies, and they gradually progressed. The neuropathic pain was protracted, despite implantation of a dorsal column stimulator and administration of a wide variety of medications and therapies. The symptoms were unresponsive to both inpatient and outpatient treatments, which resulted in a misdiagnosis of psychogenic pain for more than a decade. Diagnostic scans obtained by computed tomography, ultrasonography, and nuclear scintigraphy confirmed a popliteal fossa mass. INTERVENTIONA high, large posterior tibial nerve neurilemoma was found intraoperatively, positioned just below the sciatic nerve bifurcation with extensive degenerative features and hemorrhages. Surgical resection provided immediate recovery. CONCLUSIONPeripheral nerve tumors are rarely acknowledged clinical entities. Chronic unexplained foot and calf pain and a positive Tinel’s sign should raise suspicion of posterior tibial nerve neurilemoma. Even in patients who have had such tumors for a decade, surgical resection remains the treatment of choice.
The effectiveness of personal construct psychotherapy in clinical practice: A systematic review and meta-analysis

Abstract This study updates a systematic review of the effectiveness of personal construct psychotherapy and refines a previous meta-analysis by focusing on studies conducted in clinical settings. Twenty-seven studies satisfied the criteria for the systematic review, including 20 in clinical settings. Meta-analysis of the latter provided strong evidence of an advantage of personal construct psychotherapy over a no-treatment control; this benefit was maintained at follow-up. Meta-analysis of studies with an active treatment control group provided no evidence of the superiority or inferiority of personal construct psychotherapy. The available research justifies the practice of personal construct psychotherapy with clients in clinical practice, but conclusions must be tempered by the small number of studies and their methodological shortcomings.
Validität des BIP und des NEO-PI-R

Zusammenfassung. Die vorliegende Studie untersuchte die konkurrente Validitat eines explizit berufsbezogenen (BIP) und eines allgemeinen Personlichkeitsverfahrens (NEO-PI-R) zur Erklarung objektiver und subjektiver Berufserfolgskriterien. Als objektive Kriterien wurden Bruttoeinkommen und Berufsstatus erhoben, stellen- sowie umfeldbezogene Arbeitszufriedenheit und der subjektiv eingeschatzte Berufserfolg dienten hingegen als subjektive Kriterien des beruflichen Erfolges. Anhand einer Stichprobe berufstatiger Erwachsener wurde einerseits die Validitat der beiden Personlichkeitstests separat untersucht, andererseits wurde der inkrementelle Anteil bestimmt, den BIP und NEO-PI-R zur Varianzaufklarung uber den jeweils anderen Test hinaus lieferten. Unter Kontrolle verschiedener mit Berufserfolg in Beziehung stehender Variablen (Alter, Geschlecht, Ausbildungsniveau, Durchschnittsnote, Dauer der Tatigkeit) leisteten beide Verfahren bedeutsame Beitrage zur Erklarung der Varianz objektiver und subjektiver Berufser.
The Possibilities and Limitations of Curriculum-Based Science Inquiry Interventions for Challenging the “Pedagogy of Poverty”

Low-income and minority students in the U.S. are disproportionately subjected to didactic, teacher-controlled instruction—a phenomenon called “the pedagogy of poverty” (Haberman, 1991). This study examined the role that curriculum-based interventions could play in addressing these equity issues in science education. Eight teachers from three demographically diverse urban schools participated. Teaching in intervention classrooms was more inquiry-based and less didactic than in control classrooms, and differences in control/intervention teaching were most pronounced at the two higher-need schools. Learning benefits were found for intervention students at these two schools. Findings suggested both potential and limitations of curriculum-based interventions in challenging the pedagogy of poverty.
Thinking in space: the lexis of thinking from a cognitive perspective

ABSTRACT An in-depth account of how English speakers think about thinking, using perspectives from etymology, metaphor and cognitive linguistics. Cognitive linguistics addresses how we conceptually structure and linguistically categorize experience in order to render our world coherent and accessible. One of the ways we do so is through the creation of spatial metaphors. In cognitive theory, language is not regarded as a representation of objective reality, but rather, as the product of our interaction with the world as entities in three-dimensional space. The metaphors we use to structure experience conceptually are grounded in this interaction. Our ability to generate metaphors makes it possible for us to get a mental and linguistic grip on abstract concepts by representing them as tangible, concrete entities situated in space. Hence, from a cognitive perspective, metaphors are much more than occasional ornamental figures of speech occurring primarily in literary contexts; rather, they are all-pervasive components of everyday language and reflections of how we cognitively structure our world. It should come as no surprise then that, as we shall see, metaphorical expressions are particularly prevalent in the lexis of that most abstract of realms, the realm of thinking.
Effects of a resistance exercise programme on the performance of inactive older adults

Although published studies have indicated the effectiveness of strength exercise for improving muscle strength and functional and neuromotor performance in older adults, there is limited evidence concerning the effects and the intensity of a resistance exercise programme. This study aimed to evaluate the effects of a 12-week high- and moderate-resistance exercise programme on functional and neuromotor performance in healthy, inactive older adults. In total, 33 sedentary people (aged 60–74years) were assigned to one of three groups: control; high resistance exercise; and moderate resistance exercise. All three groups were evaluated in the pre- and post-exercise period using the 6-minute walk test, whole body reaction time and one leg stance time. After the exercise period, both resistance exercise groups significantly improved their lower body strength, functional performance (as measured by the 6-minute walk test), whole body reaction time and one leg stance time. Functional and neuromotor performance imp.
Review of Maximum Power Point Tracking approaches suitable for PV systems under Partial Shading Conditions

Maximum Power Point Tracking (MPPT) is an important consideration in Photovoltaic (PV) Systems, particularly as these systems increase in size and are exposed to non-uniform environmental conditions. Conventional MPPT techniques are designed to track the Maximum Power Point under uniform conditions where there is a single maximum power. Under non-uniform environmental conditions, with bypass diodes integrated into the circuit, the Power-Voltage characteristics become more complex resulting in multiple local maxima. Under such conditions, conventional MPPT techniques cannot track the global maxima and may result in considerable energy losses. This review paper explores the approaches designed to mitigate the complexities arising from non-uniform environmental conditions in PV system operation.
Thrombotic obstruction of a mechanical prosthetic valve in tricuspid position.

A 43-year-old woman was admitted to the hospital for progressive exertional dyspnea and abdominal distention of several weeks' duration. Fourteen months earlier, she had undergone mitral and tricuspid valve replacement with 29- and 33-mm mechanical prostheses (St. Jude Medical, Inc.; St. Paul, Minn), respectively, for rheumatic mitral and tricuspid valve stenosis and regurgitation. Anticoagulation had been maintained by her local doctor; the international normalized ratio (INR) was 3.28 upon admission, although warfarin had been discontinued for a week because of hemorrhoidal bleeding about 2 months before this admission. Two-dimensional color Doppler echocardiography revealed a stenotic tricuspid valve prosthesis with mild regurgitation; the mean pressure gradient was 16.1 mmHg. Fluoroscopy showed that both cusps of the tricuspid prosthesis were stuck in a partially open position (Fig. 1). Fig. 1 Fluoroscopic examination shows that A) during the diastolic phase, the leaflets of both prosthetic valves were widely open, and B) during the systolic phase, both leaflets of the mitral valve prosthesis were closed, but those of the tricuspid valve . Reoperation was performed with the patient under mild hypothermic cardioplegic cardiac arrest. The right atriotomy unexpectedly revealed a fixed fibrous rind that lined the whole right atrium. Therefore, a “rindotomy” was performed in order to expose the prosthesis. A plane of cleavage was created between the thrombus and the atrial wall and was progressively enlarged by blunt dissection. The thrombus was firmly adhered to the fibrous rind. After a total thrombectomy, the tricuspid valve prosthesis, which had been implanted in the anti-anatomic position, was exposed. The leaflets were in a fixed, partially open position due to thrombus (Fig. 2). The prosthesis was explanted and replaced with a new mechanical valve (St. Jude Medical, Inc.). After an uneventful recovery, the patient was discharged from the hospital on the 7th postoperative day; at that time, the INR was 2.8. Fig. 2 Intraoperative view shows A) the creation of the plane of cleavage between the thrombus and the atrium wall, B) the thrombus that was found after the fibrous rind was opened, C) the prosthetic valve that was exposed after thrombus removal, and . The explanted prosthesis showed organized thrombi that involved both leaflets on the ventricular side (Fig. 3). Fig. 3 The explanted tricuspid valve prosthesis shows A) the stuck leaflets and some pannus, seen from the atrial aspect, and B) the organized thrombus that caused the leaflets to stick in a partially open position, seen from the ventricular aspect.
Bone mineral density loss in postmenopausal onset rheumatoid arthritis is not greater than premenopausal onset disease

Background: Postmenopausal onset rheumatoid arthritis (post-RA) is expected to have greater bone mineral density (BMD) loss than premenopauasal onset (pre-RA) due to estrogen deficiency and aging. This study aimed to compare the BMD status of the two RA groups with age-matched non-RA controls. Methods: The patients with RA on follow-up examination were stratified according to age of onset. Femoral neck and lumbar spine BMD (FN-BMD and LS-BMD) were assessed by DXA method. The patients of the two groups were compared with non-RA controls in regard to BMD gr/cm2 and the risk of osteoporosis (OP). Results: Forty-eight post-RA and 94 pre-RA were compared with 31 and 57 age-matched controls. FN-BMD gr/cm2 and LS-BMD gr/cm2 in both groups of RA was significantly lower than the controls (P=0.001 for all). In post-RA, FN-BMDgr/cm2 was 16% lower than controls versus 21% in pre-RA, whereas, LS-BMD reductions were 5% and 12%, respectively (P=NS). FN-OP was observed in 32(68%) and 9 (29%) post-RA and controls (P=0.001) versus 29 (30.8%) and 4 (7%) pre-RA and controls, respectively (P=0.001). Corresponding percentages for LS-OP in post-RA and controls were (37.5% vs 35.5%, P=0.52) and in pre-RA and controls were (21.3% vs 3.5%, P=0.002), respectively. Risk of osteoporosis at either measurement sites of FN or LS in post-RA increased by the adjusted odds of 1.54(95% CI, 0.60-3.9, P=0.36) and in pre-RA by the adjusted odds of 5 (95% CI, 1.78-14.5, P=0.002), respectively. Conclusion: These findings indicate that BMD loss in post-RA is not greater than pre-RA as expected. It is possible that estrogen deficiency by modulating immunologic reactions compensates the negative effects of estrogen deprivation on bone mass in post-RA patients.
A Framework for Determining Highway Truck-Freight Benefits and Economic Impacts

Effective truck-freight transportation is critical to both national and local economic competitiveness. Given limited institutional funding, a rational investment prioritization framework is needed for decision makers that supports allocating funding to the most effective projects. However, there is no known nationally-accepted framework for analyzing the full range and full impact of freight related projects. In light of this, this paper proposes a method for not only calculating the direct freight benefits, but also the larger economic impacts of transportation projects. Measurable and critical freight related benefits resulting from transportation investments are developed from a review of the literature, as well as technical input from collaborative meetings with stakeholder groups in Washington State. The identified direct transportation benefits included in the methodology are travel time savings, operating cost savings, and environmental impacts. These are estimated using regional transportation demand models, and additional factors. Economic impacts are estimated using a regional Computable General Equilibrium (CGE) model. The total project impacts are estimated combining the outputs of the transportation model and an economic model. A Washington State highway widening project is used as a case study to demonstrate the method. The proposed method is transparent, and can be used to identify total freight specific benefits and generated impacts. This framework will ultimately be used to enhance Washington State’s infrastructure investment prioritization process.
Money Volatility and Labour Demand Uncertainty in a Unionised Economy

We insert four basic assumptions in an otherwise standard real business cycle model: monopolistic unions, short term nominal wage contracts, stochastic money supply and endogenous growth. The resulting economy exhibits a number of interesting features. First, unions face an uncertain labour demand prospect and, due to increasing labour disutility, impose a risk premium over the usual monopolistic wage. Second, the risk premium reduces the natural level of employment and depresses the long term rate of growth so that uncertainty reveals to be harmful on both accounts. Third, thanks to the endogenous technology, even if nominal rigidities are short termed, monetary perturbations turn out to have permanent e¤ects on output and, in this respect, appear to be empirically equivalent to permanent supply side perturbations. Finally, the model predicts a positive relationship between the level of in‡ation and its variability and a negative relationship between the variability of in‡ation and output and the rate of growth. In this sense, we o¤er an explanation for some well known facts in empirical macroeconomics.
Constructing Africa(ns) in international relations theory: bridging a theoretical abyss

Africa(ns) are currently marginalised within the discipline of International Relations. This thesis explores the possibility that employing a constructivist approach could facilitate the inclusion of Africa as an object of study and Africans as potential agents of IR knowledge within the discipline by bridging a theoretical abyss. Two discourses, namely the rationalist and Africanist, are identified. They frame the sides of the theoretical abyss to which Africa(ns) have been marginalised within IR. These discourses adhere to the opposing analytical approaches which constitute the Third Debate, namely rationalism and reflectivism. This thesis proposes two theoretical reconstructions that can facilitate the bridging of this theoretical abyss. The theoretical reconstructions are explicated by employing different research stances. The researcher is situated within the intellectual space afforded by the boundaries of the discipline in order to propose the first reconstruction. The second theoretical reconstruction is proposed by problematising the boundaries the discipline of IR. This study found that constructivism facilitates the process of establishing the middle ground between rationalism and reflectivism and in so doing could include Africa as an object of study. It also found that the intervention of constructivism facilitated a necessary change in the culture of the discipline to create the possibility of extending the notion of engaged pluralism and re-imagining the discipline as a disciplinary community of difference. This leads to the opening up of the necessary dialogical space to include Africans as potential agents of IR knowledge. Constructivism is therefore the mutually constituting link between the two proposed theoretical reconstructions as they are made possible by its intervention in the discipline.
Dynamic identification of robot with a load-dependent joint friction model

Usually, the joint transmission friction model for robots is composed of a viscous friction force and of a constant dry friction force. However, according to the Coulomb law, the dry friction force depends linearly on the load driven by the transmission. It follows that this effect must be taken into account for robots working with large variation of the payload or inertial and gravity forces, and actuated with transmissions as speed reducer, screw-nut or worm gear. This paper proposes a new inverse dynamic identification model for n degrees of freedom (dof) serial robot, where the dry friction force is a linear function of both the dynamic and the external forces. A new identification procedure groups all the joint data collected while the robot is tracking planned trajectories with different payloads to get a global least squares estimation, in one step, of inertial and new friction parameters. An experimental validation is carried out with a 1 dof prismatic joint composed of a Star high precision ball screw drive positioning unit, which allows large and easy variations of the inertial and gravity forces.
The ICF-CY and children with communication disabilities

The International Classification of Functioning, Disability and Health Children and Youth Version (ICF-CY) (World Health Organization, ) provides a relevant framework for consideration of children with communication disability by professionals such as speech-language pathologists and audiologists. This paper describes the international and interdisciplinary context in which the ICF-CY was created; then focuses on three major considerations in the development of the ICF-CY: the inclusion of universal perspectives on the rights of children, the need for adherence to the structure of the ICF and the specific issues regarding the use of qualifiers with children. The prevalence and incidence of children with communication and hearing disability is outlined and the literature relating to core sets of ICF-CY codes for children with communication disability is discussed. Next, the ICF-CY is applied to assessment and intervention practices of speech-language pathologists. To exemplify the status quo, the primary focus of 56 assessment tools and 22 intervention approaches for children with speech impairment is categorized using the ICF-CY. This analysis demonstrates speech-language pathologists' current emphasis on Body Functions when working with children with speech impairment. Finally, this paper presents a discussion of role of the ICF-CY in advocacy for children with communication disability.
