Mentoring and other valued components of counselor educator doctoral training: a Delphi study

Purpose Counselor educators graduating from accredited doctoral programs complete training in counseling, supervision, teaching, research, scholarship, leadership, and advocacy. The purpose of this paper is to investigate the valued components of doctoral degree training in counselor education among new graduates. Design/methodology/approach Recent graduates in full-time counselor education positions were surveyed using the Delphi method to determine which aspects of their doctoral training best prepared them for their current positions. Findings The participants valued or desired training in teaching, research, supervision, and potential mentorship. Research limitations/implications A serendipitous finding of the research was that mentorship, which was not a deliberate training feature, was highly valued by new counselor educators. Further research on which mentorship styles are best suited for counselor educator training is necessary. Continued training in teaching, research, and supervision is also necessary. Practical implications Some form of mentoring is desirable in counselor educator training programs to facilitate transition from year to year of doctoral study, as well as to assist transition from the role of student to faculty. Originality/value A desire to be mentored by faculty, specifically for students in counselor education doctoral programs, is revealed.
Detection of MMORPG Misconducts Based on Action Frequencies, Types and Time-Intervals

This paper describes an application of data mining to detecting misconducts, such as use of bots and cheats, in Massively Multiplayer Online Role-Playing Games (MMORPGs). A method is proposed that exploits the information on action frequencies, types, and intervals available in the targeted MMORPG log data. The aforementioned information is used as the input to a support vector machine. Evaluation results, using log data, available in rollback database, from Cabal Online, confirm the effectiveness of the proposed method.
Interspike Intervals, Receptive Fields, and Information Encoding in Primary Visual Cortex

In the primate primary visual cortex (V1), the significance of individual action potentials has been difficult to determine, particularly in light of the considerable trial-to-trial variability of responses to visual stimuli. We show here that the information conveyed by an action potential depends on the duration of the immediately preceding interspike interval (ISI). The interspike intervals can be grouped into several different classes on the basis of reproducible features in the interspike interval histograms. Spikes in different classes bear different relationships to the visual stimulus, both qualitatively (in terms of the average stimulus preceding each spike) and quantitatively (in terms of the amount of information encoded per spike and per second). Spikes preceded by very short intervals (3 msec or less) convey information most efficiently and contribute disproportionately to the overall receptive-field properties of the neuron. Overall, V1 neurons can transmit between 5 and 30 bits of information per second in response to rapidly varying, pseudorandom stimuli, with an efficiency of ∼25%. Although some (but not all) of our results would be expected from neurons that use a firing-rate code to transmit information, the evidence suggests that visual neurons are well equipped to decode stimulus-related information on the basis of relative spike timing and ISI duration.
Extendability in the Sheaf-theoretic Approach: Construction of Bell Models from Kochen-Specker Models

Extendability of an empirical model was shown by Abramsky&Brandenburger to correspond in a unified manner to both locality and non-contextuality. We develop their approach by presenting a refinement of the notion of extendability that can also be useful in characterising the properties of sub-models. The refinement is found to have another useful application: it is shown that a particular canonical extension, when well-defined, may be used for the construction of Bell-type models from models of more general kinds in such a way that the constructed model is equivalent to the original in terms of non-locality/contextuality. This is important since on practical and foundational levels, the notion of locality in Bell-type models can more easily be motivated than the corresponding general notion of contextuality. We consider examples of Bell-type models generated from some standard examples of contextual models, including an entire class of Kochen-Specker-like models. This exposes an intriguing relationship between the simplest possible contextual model (the contextual triangle) and Popescu-Rohrlich no-signalling correlations.
Risk of Pelvic Inflammatory Disease Following Chlamydia trachomatis Infection: Analysis of Prospective Studies With a Multistate Model

Our objective in this study was to estimate the probability that a Chlamydia trachomatis (CT) infection will cause an episode of clinical pelvic inflammatory disease (PID) and the reduction in such episodes among women with CT that could be achieved by annual screening. We reappraised evidence from randomized controlled trials of screening and controlled observational studies that followed untreated CT-infected and -uninfected women to measure the development of PID. Data from these studies were synthesized using a continuous-time Markov model which takes into account the competing risk of spontaneous clearance of CT. Using a 2-step piecewise homogenous Markov model that accounts for the distinction between prevalent and incident infections, we investigated the possibility that the rate of PID due to CT is greater during the period immediately following infection. The available data were compatible with both the homogenous and piecewise homogenous models. Given a homogenous model, the probability that a CT episode will cause clinical PID was 0.16 (95% credible interval (CrI): 0.06, 0.25), and annual screening would prevent 61% (95% CrI: 55, 67) of CT-related PID in women who became infected with CT. Assuming a piecewise homogenous model with a higher rate during the first 60 days, corresponding results were 0.16 (95% CrI: 0.07, 0.26) and 55% (95% CrI: 32, 72), respectively.
Construction and refinement of panoramic mosaics with global and local alignment

This paper presents techniques for constructing full view panoramic mosaics form sequences of images. Our representation associates a rotation matrix (and optionally a focal length) with each input image, rather than explicitly projecting all of the images onto a common surface (e.g., a cylinder). In order to reduce accumulated registration errors we apply global alignment (block adjustment) to whole sequence of images, which results in an optimal image mosaic (in the least squares sense). To compensate for small amounts of motion parallax introduced by translations of the camera and other unmodeled distortions we develop a local alignment (deghosting) technique which warps each image based on the results of pairwise local image registrations. By combining both global and local alignment we significantly improve the quality of our image mosaics thereby enabling the creation of full view panoramic mosaics with hand-held cameras.
Endothelial Cell-Derived Nitric Oxide Enhances Aerobic Glycolysis in Astrocytes via HIF-1α-Mediated Target Gene Activation

Astrocytes exhibit a prominent glycolytic activity, but whether such a metabolic profile is influenced by intercellular communication is unknown. Treatment of primary cultures of mouse cortical astrocytes with the nitric oxide (NO) donor DetaNONOate induced a time-dependent enhancement in the expression of genes encoding various glycolytic enzymes as well as transporters for glucose and lactate. Such an effect was shown to be dependent on the hypoxia-inducible factor HIF-1α, which is stabilized and translocated to the nucleus to exert its transcriptional regulation. NO action was dependent on both the PI3K/Akt/mTOR and MEK signaling pathways and required the activation of COX, but was independent of the soluble guanylate cyclase pathway. Furthermore, as a consequence of NO treatment, an enhanced lactate production and release by astrocytes was evidenced, which was prevented by downregulating HIF-1α. Several brain cell types represent possible sources of NO. It was found that endothelial cells, which express the endothelial NO synthase (eNOS) isoform, constitutively produced the largest amount of NO in culture. When astrocytes were cocultured with primary cultures of brain vascular endothelial cells, stabilization of HIF-1α and an enhancement in glucose transporter-1, hexokinase-2, and monocarboxylate transporter-4 expression as well as increased lactate production was found in astrocytes. This effect was inhibited by the NOS inhibitor l-NAME and was not seen when astrocytes were cocultured with primary cultures of cortical neurons. Our findings suggest that endothelial cell-derived NO participates to the maintenance of a high glycolytic activity in astrocytes mediated by astrocytic HIF-1α activation.
Expression pattern of osteopontin and αvβ3 integrin during the implantation window in infertile patients with early stages of endometriosis.

BACKGROUND To study endometrial receptivity in terms of osteopontin (OPN) and αvβ3 integrin expression and co-expression in infertile women with early stages of endometriosis. METHODS We investigated the immunohistochemical expression and co-expression of OPN and αvβ3 integrin in the endometrium of 20 infertile patients with Stage I or II endometriosis as the only detectable cause of infertility, 20 infertile patients with unexplained infertility and 20 fertile women undergoing tubal sterilization. Two endometrial biopsies were performed during a single menstrual cycle (postovulatory Day +7 to +8 and 4 days later) in each subject. RESULTS No statistically significant differences regarding OPN and αvβ3 integrin expression were found between infertile patients with endometriosis and the two control groups. There was no significant correlation between OPN and αvβ3 integrin staining intensity in the mid-luteal phase biopsies in any of the groups studied. CONCLUSIONS Endometrial OPN and αvβ3 integrin expression or co-expression is not impaired during the window of implantation in patients with Stage I-II endometriosis. Further studies are needed to determine whether these results imply normal endometrial receptivity in such patients or add to the increasing uncertainty about the clinical value of assessing the endometrium with these markers of implantation.
Postoperative Arrhythmias after Cardiac Surgery: Incidence, Risk Factors, and Therapeutic Management

Arrhythmias are a known complication after cardiac surgery and represent a major cause of morbidity, increased length of hospital stay, and economic costs. However, little is known about incidence, risk factors, and treatment of early postoperative arrhythmias. Both tachyarrhythmias and bradyarrhythmias can present in the postoperative period. In this setting, atrial fibrillation is the most common heart rhythm disorder. Postoperative atrial fibrillation is often self-limiting, but it may require anticoagulation therapy and either a rate or rhythm control strategy. However, ventricular arrhythmias and conduction disturbances can also occur. Sustained ventricular arrhythmias in the recovery period after cardiac surgery may warrant acute treatment and long-term preventive strategy in the absence of reversible causes. Transient bradyarrhythmias may be managed with temporary pacing wires placed at surgery, but significant and persistent atrioventricular block or sinus node dysfunction can occur with the need for permanent pacing. We provide a complete and updated review about mechanisms, risk factors, and treatment strategies for the main postoperative arrhythmias.
Social commerce: A literature review

The increasing popularity of social networking is providing new opportunities for businesses in electronic commerce. It is evolving in order to adopt Web 2.0 capabilities to support online customer interactions and achieve greater economic value. This trend is referred to as social commerce. This study offers the result of a Systematic Literature Review (SLR) to explain the concept of social commerce. In order to elaborate this article, 64 papers were considered from the main digital libraries that index computer science conferences and journals. Applying a systematic analysis to these papers, it was possible to summarize the existing evidence concerning the social commerce and outline some open challenges.
Are Playgrounds a Case of Occupational Injustice? Experiences of Parents of Children with Disabilities

Abstract:Occupational injustice refers to a setting or situations that can restrict a person in performing an occupation. Because a playground is a setting that can restrict children with disabilities from the occupation of playing, this paper frames playground accessibility in terms of occupational justice. This study interviewed 18 parents of children with disabilities about their children's experiences with playgrounds. Examining playgrounds from an occupational justice perspective can be a means to advocate for accessible playgrounds as a first step towards helping children with disabilities participate in play activities in this environment.
A flow cytometric method for characterization of circulating cell-derived microparticles in plasma

Background and aim Previous studies on circulating microparticles (MPs) indicate that the majority of MPs are of a size below the detection limit of most standard flow cytometers. The objective of the present study was to establish a method to analyze MP subpopulations above the threshold of detection of a new generation BD FACSAria™ III digital flow cytometer. Methods We analyzed MP subpopulations in plasma from 24 healthy individuals (9 males and 15 females). MPs were identified according to their size (<1.0-µm), by Lactadherin-FITC labelling, and by exposure of cell-specific markers. The sensitivity of the flow cytometer was tested against that of a previous-generation instrument FC500. Reproducibility of the FACSAria and our set-up was investigated, and the percentage of phosphatidylserine (PS) exposing MPs binding Lactadherin was determined. Results By using a flow cytometric approach we identified and quantitated MPs derived from platelets, monocytes, erythrocytes and endothelial cells. In addition, levels of tissue factor-positive MPs were determined. The FACSAria demonstrated improved sensitivity and increased MP detection range compared to the FC500 instrument. The reproducibility of PS+PMP and PS+MP measurements was 11.7 and 23.2%, respectively. When expressed as a percentage of total MPs, the PS-positive MP population represented 15.1±5.5%, and PS-positive MPs were significantly increased in men. Conclusion We have established a method to measure MPs above the detection limit of a new generation flow cytometer and derived from a number of cell-types in a healthy population of men and women.
Cowles Foundation for Research in Economics at Yale University Cowles Foundation Discussion Paper No . 1421 R April 2004 ROBUST MECHANISM DESIGN

The mechanism design literature assumes too much common knowledge of the environment among the players and planner. We relax this assumption by studying implementation on richer type spaces. We ask when ex post implementation is equivalent to interim (or Bayesian) implementation for all possible type spaces. The equivalence holds in the case of separable environments; examples of separable environments arise (1) when the planner is implementing a social choice function (not correspondence); and (2) in a quasilinear environment with no restrictions on transfers. The equivalence fails in general, including in some quasilinear environments with budget balance. In private value environments, ex post implementation is equivalent to dominant strategies implementation. The private value versions of our results o¤er new insights into the relation between dominant strategy implementation and Bayesian implementation.
The Influence of Working-Memory Demand and Subject Performance on Prefrontal Cortical Activity

Brain imaging and behavioral studies of working memory (WM) converge to suggest that the ventrolateral prefrontal cortex (PFC) mediates a capacity-limited storage buffer and that the dorsolateral PFC mediates memory organization processes that support supracapacity memory storage. Previous research from our laboratory has shown that the extent to which such memory organization processes are required depends on both task factors (i.e., memory load) and subject factors (i.e., response speed). Task factors exert their effects mainly during WM encoding while subject factors exert their effects mainly during WM retrieval. In this study, we sought to test the generalizability of these phenomena under more difficult memory-demand conditions than have been used previously. During scanning, subjects performed a WM task in which they were required to maintain between 1 and 8 letters over a brief delay. Neural activity was measured during encoding, maintenance, and retrieval task periods using event-related functional magnetic resonance imaging. With increasing memory load, there were reaction time increases and accuracy rate decreases, ventrolateral PFC activation decreases during encoding, and dorsolateral PFC activation increases during maintenance and retrieval. These results suggest that the ventrolateral PFC mediates WM storage and that the dorso-lateral PFC mediates strategic memory organization processes that facilitate supracapacity WM storage. Additionally, high-performing subjects showed overall less activation than low-performing subjects, but activation increases with increasing memory load in the lateral PFC during maintenance and retrieval. Low-performing subjects showed overall more activation than high-performing subjects, but minimal activation increases in the dorsolateral PFC with increasing memory load. These results suggest that individual differences in both neural efficiency and cognitive strategy underlie individual differences in the quality of subjects' WM performance.
SEMIFAR models - a semiparametric framework for modelling trends, long-range dependence and nonstationarity

Time series in many areas of application often display local or global trends. Typical models that provide statistical \explanations" of such trends are, for example, polynomial regression, smooth bounded trends that are estimated nonparametrically, and di erence-stationary processes such as, for instance, integrated ARIMA processes. In addition, there is a fast growing literature on stationary processes with long memory which generate spurious local trends. Visual distinction between the large variety of possible models, and in particular between deteministic, stochastic and spurious trends, can be very di cult. Also, for some time series, several \trend generating" mechanisms may occur simulateneously. In this paper, a class of semiparametric fractional autoregressive models (SEMIFAR) is proposed that includes deterministic trends, di erence stationarity and stationarity with shortand long-range dependence. Parameters characterizing stochastic dependence and stochastic trends, including a fractional and an integer di erencing parameter, can be estimated by maximum likelihood. Deterministic trends are estimated by kernel smoothing. In combination with automatic model and bandwidth selection, the proposed method allows for exible modelling of time series and helps the data analyst to decide whether the observed process contains a stationary shortor long-memory component, a di erence stationary component, and/or a deterministic trend component. Data examples from various elds of application illustrate the method. Finite sample behaviour is studied in a small simulation study.
On the definition of averagely trapped surfaces

Previously suggested definitions of averagely trapped surfaces are not well defined properties of 2-surfaces and can include surfaces in flat spacetime. A natural definition of averagely trapped surfaces is that the product of the null expansions be positive on average. A surface of spherical topology is averagely trapped in the latter sense if and only if its area A and Hawking mass M satisfy the isoperimetric inequality 16 pi M2>A, with similar inequalities existing for other definitions of quasi-local energy.
Nonlinear design of active suspensions

We propose a new nonlinear backstepping design for active suspension systems which aims to improve the tradeoff between ride quality and suspension travel. We show that the intentional introduction of nonlinearity through the controller into an otherwise linear system can be beneficial in cases where the desired closed-loop response is different in different operating regions.
The Impact of Knowledge Coordination on Virtual Team Performance Over Time

As the role of virtual teams in organizations becomes increasingly important, it is crucial that companies identify and leverage team members' knowledge. Yet, little is known of how virtual team members come to recognize one another's knowledge, trust one another's expertise, and coordinate their knowledge effectively. In this study, we develop a model of how three behavioral dimensions associated with transactive memory systems (TMS) in virtual teams-expertise location, task-knowledge coordination, and cognition-based trust-and their impacts on team performance change over time. Drawing on the data from a study that involves 38 virtual teams of MBA students performing a complex web-based business simulation game over an 8-week period, we found that in the early stage of the project, the frequency and volume of task-oriented communications among team members played an important role in forming expertise location and cognition-based trust. Once TMS were established, however, task-oriented communication became less important. Instead, toward the end of the project, task-knowledge coordination emerges as a key construct that influences team performance, mediating the impact of all other constructs. Our study demonstrates that TMS can be formed even in virtual team environments where interactions take place solely through electronic media, although they take a relatively long time to develop. Furthermore, our findings show that, once developed, TMS become essential to performing tasks effectively in virtual teams.
Níveis dos sintomas climatéricos em mulheres fisicamente ativas e insuficientemente ativas

O objetivo do estudo foi avaliar o nivel de sintomatologia em mulheres fisicamente ativas e insuficientemente ativas. A amostra foi composta por 60 mulheres entre 40 a 60 anos (media 49,4), sendo 30 fisicamente ativas e 30 insuficientemente ativas. Caracteristicas sociodemograficas e clinicas foram avaliadas por instrumentos padrao, a sintomatologia climaterica pelo Indice Menopausal de Blatt-Kupperman (IMBK) e o nivel de atividade fisica, pela versao curta do International Physical Activity Questionnaire (IPAQ). O programa SSPS, versao 18.0, foi utilizado em abrangencias descritivas e inferenciais. O Test t student e o Test χ² revelaram diferencas nao significativas em caracteristicas sociodemograficas entre os grupos (p>0.05). Dados do IMBK e os referentes a todos os sintomas, com excecao da depressao e zumbidos, revelaram niveis significativos, sendo todos mais baixos para as mulheres ativas (p<0.05). Uma Analise de regressao linear relativa aos sintomas climatericos mostrou que a pratica regular de atividade fisica, pode reduzir o valor do IMBK ate 12 pontos. A atividade fisica regular faz diminuir a intensidade dos sintomas climatericos em mulheres de meia idade.
