Adding Roles to CORBA Objects

Traditional IDLs were defined for describing the services that objects offer, but not those services they require from other objects, nor the relative order in which they expect their methods to be called. Some of the existing proposals try to add protocol information to object interfaces, but most of them fail to do so in a modular way. In this paper we propose an extension of the CORBA IDL that uses a sugared subset of the polyadic /spl pi/-calculus for describing object service protocols, based on the concept of roles. Roles allow the modular specification of the observable behavior of CORBA objects, reducing the complexity of the compatibility tests. Our main aim is the automated checking of protocol interoperability between CORBA objects in open component-based environments, using similar techniques to those used in software architecture description and analysis. In addition, our proposal permits the study of substitutability between CORBA objects, as well as the realization of dynamic compatibility tests during their runtime execution.
Mystery of the Unknown: Revisiting Tacit Knowledge in the Organizational Literature

Purpose – This study aims to discuss how organizational researchers use the concept of tacit knowledge. The concept has become a “buzzword” in the last decade and has given rise to an extensive literature. The current study views tacit knowledge as a crucial concept that may help link individual understanding and skills and organizational routines and capabilities, a rare topic of discussion in extant literature.Design/methodology/approach – The paper also addresses some of the misunderstandings in the theoretical and empirical organizational literature on tacit knowledge. Organizational researchers usually refer to Michael Polanyi's conception of the term as tacit knowledge, though they mean Gilbert Ryle's concept of “knowing‐how” instead.Findings – Accordingly, the primordial nature of tacit knowing is lost in the transition and what is left is a linear dichotomy of tacit and explicit knowledge.Originality/value – This misunderstanding creates an obstacle in the way toward establishing the link between .
Pretransplant Malignancy as a Risk Factor for Posttransplant Malignancy After Heart Transplantation

Background Posttransplant malignancy is a major cause of death in orthotopic heart transplant recipients. Our study objective is to identify whether pretransplant malignancy increases the risk for posttransplant malignancy. Methods Using the Organ Procurement and Transplantation Network/United Network for Organ Sharing database, adult (≥18 years old) recipients of a primary orthotopic heart transplant performed between 2000 and 2012 were included. The cohort was stratified according to the presence and type of pretransplant malignancy. Outcomes were posttransplant overall, skin, solid malignancies, and posttransplant lymphoproliferative disorder. Incidence of and time to first posttransplant malignancy, accounting for death as a competing event, were calculated. Fine and Gray competing risks regression was performed to examine risk factors associated with posttransplant malignancy. Results Of 23,171 recipients, overall posttransplant malignancy was diagnosed in 2673 recipients (11.5%). The median time to overall, skin, solid posttransplant malignancies, and posttransplant lymphoproliferative disorder were 3.2 (1.6-5.7), 3.2 (1.7-5.6), 3.5 (1.7-5.9), and 2.5 years(0.8-5.2), respectively. Pretransplant malignancy increased the risk of posttransplant overall (subhazard ratio [SHR], 1.51; 95% confidence interval [95% CI], 1.27-1.81), skin (SHR, 1.55, 95% CI, 1.23-1.93), and solid organ malignancies (SHR, 1.54; 95% CI, 1.13-2.11). Pretransplant skin malignancy increased the risk of posttransplant skin malignancy (SHR, 2.79; 95% CI, 1.82-4.28). Pretransplant solid malignancy also increased the risk of posttransplant skin malignancy (SHR, 1.55; 95% CI, 1.07-2.25) but not of posttransplant solid tumors (SHR, 1.23; 95% CI, 0.69-2.19). Older, male, and white were also risk factors for posttransplant malignancy. Conclusions A history of any pretransplant malignancy was associated with increased risks of skin and solid malignancies after transplantation. The specific type of posttransplant malignancy risk differed according to the type of pretransplant malignancy.
Nonlinear time series analysis of partial discharges in electrical trees of XLPE cable insulation samples

This paper presents an investigation into the nonlinear dynamics characteristics of the partial discharge (PD) sequence measured during the propagation of typical electrical trees in XLPE cable insulation. Calculation of the correlation dimension and the largest Lyapunov exponent from the PD sequence is used to illustrate the nonlinear characteristics of the PD behavior in the electrical tree growth. The results provide strong evidence for the existence of deterministic chaos in the PD phenomenon of electrical trees, where the correlation dimension and the largest Lyapunov exponent are related with the PD activity of the tree growth, rather than a presence of random stochastic process. The fluctuating correlation dimension of the PD sequence during the branch-pine tree growth is associated with the transition of PD patterns and the change of the channel conductivity of the tree structure. It is also found that the nonlinear dynamics characteristics of the PD sequence are influenced by the applied voltage, the channel conductivity and the electrical tree shape. A possible mechanism is presented for the formation of different chaotic extents of typical electrical trees in XLPE cable insulation.
Mediterranean diet, moderate-to-high intensity training, and health-related quality of life in adults with metabolic syndrome

Background: Much recent research has focused on the benefits of the Mediterranean diet on risk factors of metabolic syndrome (MetS). In addition numerous investigations have also demonstrated that moderate and high-intensity endurance training may induce greater beneficial adaptations in body composition and cardiometabolic risk than low-intensity endurance training. How a model of Mediterranean diet with and without moderate-to-high intensity training influences health-related quality of life (HRQoL) and physical fitness in MetS patients is unknown. Design and methods: A total of 45 sedentary MetS males and females (50⊟66 years) were randomly divided into two groups: (a) hypocaloric, normoproteic Mediterranean diet (MeD); and (b) the same diet plus periodized moderate-to-high intensity training (MeDE) for 12 weeks. HRQoL (EuroQol and SF-36 questionnaires), fitness, response to submaximal exercise, and risk factors of MetS were determined before and after treatment. Results: MeD improved some physical and mental domains of HRQoL (physical function, vitality, general physical health, emotional role, and self-perception of health) and resulted in weight loss and improvement of MetS risk factors (intra-group p < 0.05). Moreover, the MeDE intervention resulted in greater improvement in these domains and the improvement of other HRQoL components (physical role, bodily pain, social function, and health profile). MeDE increased physical fitness, resulted in a better physiological response to submaximal effort and caused a greater weight loss (intra-group and inter-group, p < 0.05). Conclusions: A model of hypocaloric Mediterranean diet combined with periodized moderate-to-high intensity training may lead to greater improvement in HRQoL through a greater effect on physical and functional fitness, bodyweight, and risk factors than diet alone.
Children’s voices – Differentiating a child perspective from a child’s perspective

Abstract Objective: The aim of this paper was to discuss differences between having a child perspective and taking the child’s perspective based on the problem being investigated. Methods: Conceptual paper based on narrative review. Results: The child’s perspective in research concerning children that need additional support are important. The difference between having a child perspective and taking the child’s perspective in conjunction with the need to know children’s opinions has been discussed in the literature. From an ideological perspective the difference between the two perspectives seems self-evident, but the perspectives might be better seen as different ends on a continuum solely from an adult’s view of children to solely the perspective of children themselves. Depending on the research question, the design of the study may benefit from taking either perspective. In this article, we discuss the difference between the perspectives based on the problem being investigated, children’s capacity to express opinions, environmental adaptations and the degree of interpretation needed to understand children’s opinions. Conclusion: The examples provided indicate that children’s opinions can be regarded in most research, although to different degrees.
Constellation Design with Unequal Priors and New Distance Criteria for the Low SNR Noncoherent Rayleigh Fading Channel

Code design for the noncoherent MIMO Rayleigh fading channel is considered for constellations with unequal prior probabilities. The motivation for such constellations with unequal priors arises from recent infor- mation theoretic results at low Signal-to-noise ratio (SNR). Different distance measures like the Bhattacharya distance and J-divergence are related to the average pairwise error probability (APEP) and are employed to design single an- tenna codes of general dimension both for equal and un- equal priors. For equal priors, such codes are observed to perform at least as well, and often better than codes de- signed based on the Kullback-Liebler (KL) distance in the low SNR regime. Substantial performance gains are ob- served for codes designed with unequal prior probabilities in the low SNR regime as compared to codes designed with equal priors. I. INTRODUCTION
“More Simply Human…”: An Introduction

The articles in this special section of Contemporary Psychoanalysis have their origins in the 2012–2013 William Alanson White Psychoanalytic Society’s Colloquium Series, “More Simply Human . ” Six of the nine speakers in the series—Philip M. Bromberg, Sandra Buechler, Marilyn Charles, Mary Gail Frawley-O’Dea, Richard B. Gartner, and John Kerr—adapted their original talks for this issue, and two others—Diane Ehrensaft and Spyros D. Orfanos—have written new articles that extend and complement the ideas they presented as part of the Colloquium. One Colloquium speaker, Nancy McWilliams, is not included in this issue; however, her talk from the Series is available online as an audio file, as is Dr. Bromberg’s original presentation. The idea for the Series came from the words of Harry Stack Sullivan, who had a formative—and ultimately, profound—influence on the development of the William Alanson White Institute and whose work has inspired many to undergo training at White. I read Sullivan for the first time in my first year of graduate school, and recall that, despite all of Sullivan’s idiosyncrasies of language (or perhaps because of them), his words were often moving and inspirational. He passionately cared for and identified with the troubled patients he treated. Further, he wanted to expand the hearts and minds of his readers and students to enable them (that is, us) to better understand and truly be with patients, including those whom others might find alien or too challenging to work
Order-of-Magnitude Influence Diagrams

In this paper, we develop a qualitative theory of influence diagrams that can be used to model and solve sequential decision making tasks when only qualitative (or imprecise) information is available. Our approach is based on an order-of-magnitude approximation of both probabilities and utilities and allows for specifying partially ordered preferences via sets of utility values. We also propose a dedicated variable elimination algorithm that can be applied for solving order-of-magnitude influence diagrams.
Fuzzy dynamic parameters adaptation in the Cuckoo Search Algorithm using fuzzy logic

The proposed method in this paper describes the enhancement of the Cuckoo Search (CS) Algorithm via Lévy flights using a fuzzy system to dynamically adapt its parameters. The original CS method is compared with the proposed method called Fuzzy Cuckoo Search (FCS) on a set of benchmark mathematical functions. In this case we consider a fuzzy system to dynamically change parameters during the execution of the algorithm. Simulation results on a set of mathematical functions show that the FCS outperforms the traditional CS. In addition, we demonstrate through statistical tests that the proposed method is better than the original CS algorithm.
A Novel Fuzzy Attitude Based Bidding Strategy for Multi-attribute Auction

Auctions have recently commanded a lot of attention in the field of multi-agent systems. To be successful in open multi-attribute auctions, agents must be capable of adapting different strategies and tactics to their prevailing circumstances. This paper presents a software test-bed for studying autonomous bidding strategies in simulated auctions for procuring goods. It shows that agents' bidding strategy explore the attitudes and behaviors that help agents to manage dynamic assessment of alternative prices of goods given the different scenario conditions. Our agent also uses fuzzy techniques for the decision making: to make decisions about the outcome of auctions, and to alter the agent's bidding strategy in response to the different criteria and market conditions
The UCM-ROOM Design Method: from Use Case Maps to Communicating State Machines

Abstract A major problem we humans have in the engineering of complex, computer-based systems is understanding and defining how the required behaviour of a whole system is to be achieved by its components, without becoming lost in component-centric detail such as internal state machines and the intercomponent messages they trigger. This leads to other problems, such as, long iteration cycles during forward engineering while we try various detailed changes in attempts to fix erroneous system behaviour, and inadvertently introducing detailed changes during maintenance or reengineering that will damage whole system behaviour because there is a lack of backwards traceability to it from the details. This paper proposes and illustrates a design method for overcoming such problems that proceeds, in a systematic and traceable manner, from UCM models (use case maps), to MSC models (message sequence charts), to ROOM-style communicating-state-machine models. For concreteness in a limited space, the method is illustrated by a simple example that is not representative of the complex kinds of systems we have in mind.
Bipartite graph-based keyword query results recommendation

Relational database is widely used in people's daily life and productions. Keyword search in relational database makes people search structured information from database as using search engine. So it has become a research hotspot. In recent years, there are a lot of research works about how to use historical query information to improve query efficiency. The existing works can be divided into two main aspects: query expansion and query recommendation. These two aspects have common feature, that is, they both use the historical words to improve query efficiency. If the results of historical query can be directly recommended to the current query, the query efficiency will be improved. But there are not any works using recommended model of recommended system to help keyword search. We have found that recommended model can be used to improve efficiency. We are the first one to use bipartite graph model, and propose query result recommendation algorithm, namely, Query_base algorithm and Distance_base algorithm. Finally this paper analyzes the factors which affect the efficiency of the algorithms, and verified the performance and higher accuracy of the recommendation algorithms by experiments.
Opinions on multiple sequence alignment, and an empirical comparison of repeatability and accuracy between POY and structural alignment.

An extensive literature, special symposia, and even a formal organization (International Society for Phylogenetic Nomenclature) have been devoted to various other taxonomic proposals some of which seem far more radical and/or less utilitarian than the timeclip proposal advanced here. Thus, we now invite open discussion on the temporal-banding strategy and on timeclip-like tactics that could greatly enrich existing taxonomies while still maintaining established Linnaean traditions and nomenclatures.
Toward Hierachical Decomposition for Planning in Uncertain Environments

This work addresses the computational complexity of solving large Markov decision processes by partitioning their state spaces into nearly-independent regions. We propose a method for developing partial plans, or macros, over such regions that yields a polynomial number of macros for each region. Each macro represents knowledge about how to achieve one particular sub-goal within its region of interest, and we demonstrate a simple, lineartime rule for combining these macros into a single full policy over the region and for propagating value information between regions. We empirically demonstrate the efficacy of our approach on small MDPs, for which exact solution is feasible, and give asymptotic analyses of its scalability.
Strength Training and Testosterone Treatment Have Opposing Effects on Migration Inhibitor Factor Levels in Ageing Men

Background. The beneficial effects of testosterone treatment (TT) are debated. Methods. Double-blinded, placebo-controlled study of six months TT (gel) in 54 men aged 60–78 with bioavailable testosterone (BioT) <7.3 nmol/L and waist >94 cm randomized to TT (50–100 mg/day, n = 20), placebo (n = 18), or strength training (ST) (n = 16) for 24 weeks. Moreover, the ST group was randomized to TT (n = 7) or placebo (n = 9) after 12 weeks. Outcomes. Chemokines (MIF, MCP-1, and MIP-1α) and lean body mass (LBM), total, central, extremity, visceral, and subcutaneous (SAT) fat mass established by DXA and MRI. Results. From 0 to 24 weeks, MIF and SAT decreased during ST + placebo versus placebo, whereas BioT and LBM were unchanged. TT decreased fat mass (total, central, extremity, and SAT) and increased BioT and LBM versus placebo. MIF levels increased during TT versus ST + placebo. ST + TT decreased fat mass (total, central, and extremity) and increased BioT and LBM versus placebo. From 12 to 24 weeks, MCP-1 levels increased during TT versus placebo and MCP-1 levels decreased during ST + placebo versus placebo. Conclusion. ST + placebo was associated with decreased MIF levels suggesting decreased inflammatory activity. TT may be associated with increased inflammatory activity. This trial is registered with ClinicalTrials.gov NCT00700024.
Coût dans le secteur de la distribution d'électricité : économies d'échelle, économies de densité et formes institutionnelles

[fre] Cout dans le secteur de la distribution d'electricite : economies d'echelle, economies de densite et formes . institutionnelles par Olivier Evrard et Bernard Lejeune . Cet article a pour objet d'evaluer empiriquement la pertinence economique (en termes d'efficience-cout) de la politique de delegation de la distribution d'electricite des communes vers des organismes ou societes extra-communales. Pour ce faire, les possibilites d'economies d'echelle et de densite au sein du secteur ainsi que les couts d'exploitation relatifs des diverses formes institutionnelles existantes sont evalues sur base de l'estimation d'une fonction de cout hedonique a court terme. [eng] Electricity Distribution Costs: Economies of Scale, Economies of Density and Institutional Forms . by Olivier Evrard and Bernard Lejeune . The purpose of this paper is to empirically evaluate the economic pertinence (in terms of cost effectiveness) of the policy of delegating local electricity distribution to non-local organisations or companies. We evaluate the sector's possibilities for economies of scale and density and the running costs of the different existing institutional forms based on the estimation of a short-term hedonic cost function.
Relational and Representational Aspects of Early Number Development.

Two experiments examined the role of representations of numerosity in children's reasoning about relations between two quantities. In the first experiment, 3- and 4-year-old children were able to solve matching-to-sample problems on the basis of both the numerosity of a focal set (number matches) and the correspondence relation between two sets (relational matches); but in a conflict condition, the younger children used only the relational information. In the second experiment, both the 3- and the 4-year-olds showed very high levels of success in inferring numerical equivalence from commutativity relations between two pairs of sets. Children were successful even when one of the sets in each pair was covered, so that children could not directly enumerate the quantities to be compared. Both findings support the notion that relational reasoning originates independently of processes for representing numerosity.
HIV Infection in Rural Villages of Cameroon

Objective: To evaluate HIV‐1 antibody seroprevalence and risk factors for HIV seropositivity in rural areas of Cameroon. Method: The prevalences of HIV antibodies in 53 villages in rural Cameroon visited during May‐October 2000 were determined with an HIV 1/2 rapid assay, standard ELISA, and western blot. Demographic data and risk factors were elicited via face‐to‐face interviews with a structured questionnaire. Results: HIV seroprevalence was 5.8% (243/4156, 95% confidence interval [CI] = 5.1‐6.6) overall, 6.3% (151/2394, 95% CI = 5.4‐7.4) among females and 5.2% (92/1762, 95% CI = 4.3‐6.4) among males. HIV seroprevalence among persons aged 15 ‐ 70 years did not differ significantly by province (5.6% in Center, 4.5% in East, 6.9% in South, and 5.8% in South‐West) (p = .10). Analysis of age‐ and genderstandardized prevalence by village across provinces indicated a near‐significant difference (nonparametric Wilcoxon signed rank test, p = .06), with highest prevalence in South‐West, followed by South, Center, and East. Multivariate analysis revealed that single women were significantly more likely to be HIV seropositive than were married or widowed women. Women with a history of sexual relations while traveling were at significantly increased risk of HIV seropositivity (OR adjusted for age and marital status = 2.4, 95% CI = 1.4‐9.7). Among men, those who reported ever having a sexually transmitted disease were at significantly increased risk of HIV‐seropositivity (OR adjusted for age = 1.8, 95% CI = 1.1‐2.8). Conclusion: We have documented a wide range of HIV prevalences among rural villages of Cameroon. Age, marital status (in women) and sexual risk factors appear to be associated with HIV infection in this setting.
International Marriage in Japan: 'Race' and 'Gender' perspectives

ABSTRACT Despite an image of ethnic and cultural homogeneity, Japan in fact is host to significant minority populations. A considerable part of these minorities derive from flows of labour migrants from the Asian periphery to Japan-a process dominated by female labour migrants who work mainly in the entertainment and sex-related industries. One social phenomenon resulting from the presence of female labour migrants is the rise in cases of international marriages. With regard to Asian women, in Japan mainly negative images prevail in their representation as entertainers and sex workers. Public discourse has almost exclusively dealt with problems they experience as hostesses and/or prostitutes, and they are hardly ever portrayed as the ordinary wives of Japanese citizens-a role in which they have much in common with Japanese wives. Previous research on the problems occurring in international marriages has mainly concentrated on the 'racial' or 'ethno-cultural' differences between the spouses and has neglect.
