K-fold generalization capability assessment for support vector classifiers

The problem of how to effectively implement k-fold cross-validation for support vector machines is considered. Indeed, despite the fact that this selection criterion is widely used due to its reasonable requirements in terms of computational resources and its good ability in identifying a well performing model, it is not clear how one should employ the committee of classifiers coming from the k folds for the task of on-line classification. Three methods are here described and tested, based respectively on: averaging, random choice and majority voting. Each of these methods is tested on a wide range of data-sets for different fold settings.
Personal experience in the diagnostic procedures in children with atopic dermatitis and food allergy

Atopic dermatitis (AD), a major health concern in children, is characterized by a multifactorial pathogenesis in which a significant role is played by foods, especially in infants (1). In addition, both diagnosis and treatment are difficult since the much in vogue diagnostic items, SPT and RAST yield varying results in terms of sensitivity, specificity, predicted positive and negative values (2-5). The diagnosis of FArelated AD relies on controlled challenge test. However, recent studies have focused on the unpredictable hazards following food challenge tests in term of immediate reactions (6). It has also been shown (7) that late reactions are frequent and that they can develop even several days after the challenge test. Aim of the present study was to evaluate in children with AD: 1) the prevalence of immediate and late reactions following challenge tests; 2) the sensitivity, specificity and predictive positive and negative values of SPT and RAST as regards both immediate and late reactions; 3) the prevalence of late reactions not preceded by immediate symptoms after challenge tests.
The Evolution of Entrepreneurial Competencies: A Longitudinal Study of University Spin‐Off Venture Emergence

This paper aims to better understand the development of entrepreneurial competencies to create new ventures within the non-commercial academic environment. We build upon the evolutionary perspective considering where resources come from to help define these competencies and explain their paths of development. The study follows the creation and early growth of four university spin-offs within the UK and Norway. We identified three competencies of opportunity refinement, leveraging, and championing that appeared crucial for the ventures to gain credibility. Although selected competencies were inherent within the academic founders, the specific competencies for venture creation had to be developed or acquired. This was achieved iteratively through entrepreneurial experience and accessing competencies from disparate actors such as industry partners and equity investors. Propositions are offered to guide future empirical research based upon our framework.
Coping among older‐adult, long‐term cancer survivors

This research focuses on the coping behavior of older adult, long‐term cancer survivors. Specifically, it identifies the personal (including race and gender) and illness/treatment characteristics of survivors that are significantly associated with the use of specific coping styles: planning, acceptance, venting, denial and seeking social support. It also examines the mediating role that these forms of coping play in terms of psychological distress: anxiety, depression and cancer‐related worries. Multivariate analysis of data from a random sample of 321 long‐term survivors in a major cancer center tumor registry is used to address the above issues. The most prominent forms of coping used by long‐term survivors were planning and acceptance; least used were venting and denial. Increased age was associated with lower use of all forms of coping, but cancer type was not. Denial as a form of coping was associated with higher anxiety, depression and cancer‐related worries. While race was not found to be a significant predictor of coping style, it was a significant predictor of three dimensions of psychological distress, anxiety, depression and cancer‐related worries, with African Americans exhibiting lower levels of distress than Whites. The relevance of these findings for health and social service practitioners is discussed. Copyright © 2005 John Wiley & Sons, Ltd.
Levitin-Polyak Well-Posedness of the System of Weak Generalized Vector Equilibrium Problems

In this paper, we introduce two types of the Levitin-Polyak well-posedness for the system of weak generalized vector equilibrium problems. By using the gap function of the system of weak generalized vector equilibrium problems, we establish the equivalent relationship between the two types of Levitin-Polyak well-posedness of the system of weak generalized vector equilibrium problems and the corresponding well-posednesses of the minimization problems. We also present some metric characterizations for the two types of the Levitin-Polyak well-posedness of the system of weak generalized vector equilibrium problems. The results in this paper are new and extend some known results in the literature.
Tooth root abscesses in New World camelids: 23 cases (1972-1994).

OBJECTIVE To determine typical clinical and radiographic findings in a group of New World camelids with tooth root abscesses and to determine outcome after medical and surgical treatment. DESIGN Retrospective case series. ANIMALS 23 llamas and alpacas with radiographic and clinical evidence of tooth root abscesses. PROCEDURE Disease history, signalment, physical and radiographic examination findings, bacteriologic culture results, treatment, and short-term and long-term outcome were retrieved from the medical records. RESULTS Local swelling was the most common clinical abnormality in camelids with tooth root abscesses. Mandibular molars were affected most commonly, and bacteriologic culture of samples from lesions often revealed facultative anaerobic bacteria. Antibiotic treatment for at least 30 days, surgical extraction of the affected tooth, and a root canal procedure were used successfully to treat tooth root abscesses. CLINICAL IMPLICATIONS Both surgical and medical treatment of tooth root abscesses may lead to successful resolution of clinical signs in New World camelids.
Dynamic of HIV-testing after arrival in France for migrants from sub-Saharan Africa: The role of both health and social care systems

Objective HIV testing is an important tool in the management of the HIV epidemic among key populations. We aimed to explore the dynamic of first-time HIV testing in France for sub-Saharan migrants after their arrival. Methods ANRS-Parcours is a retrospective life-event survey conducted from 2012 to 2013 in healthcare facilities in the Paris region, among 926 sub-Saharan HIV-infected migrants and 763 non-infected migrants. After describing the time to first HIV test in France and associated circumstances, we performed a discrete-time logistic regression to analyze the influence of socioeconomic position, contact with the healthcare system and sexual behaviors, on first-time HIV testing in France in migrants who arrived after 2000. Results Median first-time HIV testing occurred during the second year spent in France for non-infected men and women in both groups, and during the first year for men of the HIV group. The probability of testing increased with hospitalization and pregnancy for women of both groups. For non-infected men unemployment and absence of a residence permit were associated with an increased probability of HIV testing [respectively, OR = 2.2 (1.2–4.1) and OR = 2.0 (1.1–3.5)]. Unemployment was also associated with an increased probability of first-time HIV-testing for women of the HIV group [OR: 1.7 (1.0–2.7)]. Occasional and multiple sexual relationships were associated with an increased probability of first-time testing only for HIV-infected women [OR: 2.2 (1.2–4.0) and OR = 2.4 (1.3–4.6)]. Conclusion Access to first HIV testing in France is promoted by contact with the health care system and is facilitated for unemployed and undocumented migrants after arrival.However, testing should be offered more systematically and repeated in order to reduce time between HIV infection and diagnosis, especially for deprived people which are particularly vulnerable regarding HIV infection.
TSNWFET for SRAM cell application: Performance variation and process dependency

ION is increased about 25 % with the width/height (W/H) of 12/24 nm nanowire (NW) in comparison with the W/H of 12/12 nm at VG-VTH = 1 V. With these results, we have successfully fabricated NW SRAM arrays with the W/H of 5/15 nm and LG of 40 nm for the first time. Static noise margin (SNM) of 325 mV is achieved at VD = 1 V. NW height and gate oxide thickness dependency of n-ch twin silicon nanowire MOSFET (TSNWFET) on device variations is investigated. Line edge roughness and size variation are more critical than random dopant fluctuation in TSNWFET.
Trichodina heterodentata (Ciliophora) infestation on Prochilodus lineatus larvae: a host–parasite relationship study

SUMMARY Prochilodus lineatus is a freshwater fish species found in South America. It is common in aquaculture, but few studies regarding diseases of this fish have been performed. This study presents data of the occurrence of Trichodina heterodentata Duncan, 1977, as well as the pathological alterations detected by light and scanning electron microscopy (SEM). Twenty 20-day-old larvae were harvested from an earth pond and examined. Larvae showed erratic swimming on the pond edges and some had a whitish tegument. Larval smears were either impregnated with silver nitrate or stained with Giemsa stain to observe the taxonomic features of the ciliates. Five larvae were fixed in formalin solution for histopathological analysis, and another five specimens were fixed in glutaraldehyde for SEM. All larvae were diagnosed with a severe infestation by trichodinid T. heterodentata. Histological sections showed discrete hyperplasia of the gill filaments with subepithelial oedema of the secondary lamellae. In the SEM, suction areas were observed on the skin, gill and eye; corrosion and ulceration of the fins were associated with the bacterial presence of cocci on the lesions. This is the first report of T. heterodentata in P. lineatus that is responsible for an acute disease that culminates in larval mortality.
Physical Activity Among African American and Latino Middle School Girls: Consistent Beliefs, Expectations, and Experiences Across Two Sites

ABSTRACT Physical inactivity is a major public health concern. Low levels of physical activity are reported in many subgroups of women including adolescent girls. More data are needed to better understand factors related to physical activity participation in adolescent girls. Therefore, we explored adolescent girls' reasons for participating and not participating in physical activity. Two independent samples were taken in California and Texas; the total sample included thirty-four African American and Latino girls. Six focus groups were conducted by trained facilitators. Based on independent qualitative analyses, six replicated themes emerged from the focus groups. Fun, social support, and concern with body image facilitated participation in activity. In contrast, negative experiences in physical education classes, concerns about appearance after activity, and lack of opportunity impeded participation in activity. Overall, the girls showed an interest in physical activity and identified activity motivators and barriers. We discuss the implications of our findings for future research.
Social reproduction and exclusion in subject indexing: A comparison of public library OPACs and LibraryThing folksonomy

– The purpose of this paper is to highlight limits to the dominant model of social inclusion under which UK public libraries operate, to analyse how and to what extent processes of socio‐cultural exclusion emerge in the subject representation and discoverability of “non‐dominant” resources in public library OPACs, and to consider folksonomy as a solution to any issues raised. , – The paper first develops a critique of the dominant model of “inclusion” within UK public libraries, drawing on feminist and critical theories of identity. It then considers how this critique overlaps with and offers fresh insights into major debates within subject indexing, and develops a theoretical rationale for considering the potential of folksonomy to intervene in more inclusive subject‐indexing design. A user‐based critical interpretive methodology which understands OPACs as texts open to multiple interpretations is developed, and a comparative reading of standard OPACs and LibraryThing folksonomy is undertaken to evaluate the discoverability and subject representation of LGBTQ and ethnic minority resources. , – LibraryThing folksonomy offers benefits over LCSH subject indexing in the discoverability and representation of LGBTQ resources. However, the folksonomy is dominated by US taggers, and this impacts on the tagging of ethnic minority resources. Folksonomy, like traditional indexing, is found to contain its own biases in worldview and subject representation. , – The importance of subject indexing in developing inclusive library services is highlighted and a new method for evaluating OPACs is developed.
Evaluation of Antiviral Activity of Allium Cepa and Allium Sativum Extracts Against Newcastle Disease Virus

Newcastle Disease Virus (NDV) is the causative agent of the most devastating diseases affecting poultry especially in large scale production causing severe economic losses due to high mortality which may reach 100% in very virulent strains of NDV. In the present study, field samples of suspected to be infected by NDV were isolated in Embryonated chicken Eggs (ECEs) of 10 days-old via allantoic cavity for three passages, the isolated virus was identified to be NDV by Haemagglutination inhibition test (HI), electron microscope and reverse transcriptase polymerase chain reaction (RT- PCR). The antiviral effects of both onion and garlic extracts were studied on field isolates and reference strain of NDV. The antiviral effects involve the gross lesions changes of the embryo in inoculated ECEs, Haemagglutination test (HA) and Infectivity test (EID50%). The obtained results showed that most of the isolated viruses expressed subcutaneous Haemorrhage and death of the embryo at the fifth day post inoculation via allantoic cavity at the third passage of ECEs, while the field sample number (10) and the reference strain showed extensive haemorrhage and rapid death of embryos. The isolated viruses were identified to be NDV of the susceptible to be infected samples by HI using hyperimmune serum against NDV prepared in rabbit. The Mean Death Time (MDT) was calculated for the field sample number (10) and the reference strain which showed that the tested samples are velogenic strains. Electron microscopy investigation of some selected samples (of high HA titers) identified the virus as pleomorphic in shape. Some selected samples were analyzed by RT-PCR and gel electrophoresis expressing clear bands using primers against the F-gene of NDV. RT-PCR is considered as the most useful, reliable and accuret laboratory test for confirming field NDV. Brown leaves of onion (Allium Cepa) and bulbs of garlic (Allium sativum) were separately extracted and the extracts were tested for their antiviral activity against the previously isolated and identified NDV. Investigating the antiviral effects of both onion and garlic extracts on some field samples showed absence of virus activity after treatments by extracts, while samples number (10) and reference strain showed reduction of virus in HA test, subcutaneous hemorrhage and EID50%. The reduction of NDV infectivity may be due to the blocking of the attachment of the virus with the cell receptors.
Intensive Care Unit Physician's Attitudes on Do Not Resuscitate Order in Palestine

Background: There is some ambiguity concerning the do-not-resuscitate (DNR) orders in the Arabic world. DNR is an order written by a doctor, approved by the patient or patient surrogate, which instructs health care providers to not do CPR when cardiac or respiratory arrest occurs. Therefore, this research study investigated the attitudes of Intensive Care Unit physicians and nurses on DNR order in Palestine. Materials and Methods: A total of 123 males and females from four different hospitals voluntarily participated in this study by signing a consent form; which was approved by the Ethical Committee at Birzeit University and the Ministry of Health. A non-experimental, quantitative, descriptive, and co-relational method was used, the data collection was done by a three page form consisting of the consent form, demographical data, and 24 item-based questionnaire based on a 5-point-Likert scale from strongly agree (score 1) to strongly disagree (score 5). Results: The Statistical Package for Social Sciences (SPSS) software program version 17.0 was used to analyze the data. Finding showed no significant relationship between culture and opinion regarding the DNR order, but religion did. There was statistical significance difference between the physicians' and nurses' religious beliefs, but there was no correlation. Moreover, a total of 79 (64.3%) physicians and nurses agreed with legalizing the DNR order in Palestine. Conclusion: There was a positive attitude towards the legalization of the DNR order in Palestine, and culture and religion did not have any affect towards their attitudes regarding the legalization in Palestine.
Bank Loans Non-Linear Structure of Pricing: Empirical Evidence from Sovereign Debts

The paper suggests an innovative contribution to the investigation of banking liabilities pricing contracted by sovereign agents. To address fundamental issues of banking, the study focuses on the determinants of the up-front fees (the up-front fee is a charge paid out at the signature of the loan arrangement). The investigation is based on a uniquely extensive sample of bank loans contracted or guaranteed by 58 less-developed countries sovereigns in the period from 1983 to 1997. The well detailed reports allow for the calculation of the equivalent yearly margin on the utilization period for all individual loan. The main findings suggest a significant impact of the renegotiation and agency costs on front-end borrowing payments. Unlike the sole interest spread, the all-in interest margin better takes account of these costs. The model estimates however suggest the non-linear pricing is hardly associated with an exogenous split-up intended by the borrower and his banker to cover up information. Instead the up-front payment is a liquidity transfer as described by Gorton and Kahn (2000) to compensate for renegotiation and monitoring costs. The second interesting result is that banks demand payment for all types of sovereign risk in an identical manner public debt holders do. The difference is that, unlike bond holders, bankers have the possibility to charge an up-front fee to compensate for renegotiation costs. Hence, beyond the information related issues, the higher complexity of the pricing design makes bank loan optimal for lenders on sovereign capital markets, especially relative to public debt, thus motivating for their presence. The paper contributes to the expanding literature on loan syndication and banking related issues. The study also has relevance for the investigation of the developing countries debt pricing.
Estimation of the survival and biting rates of Culex quinquefasciatus (Diptera: Culicidae).

The average survival and biting rates of many hematophagous insects may be estimated in the field under conditions of variable recruitment rate from relatively short runs of nulliparous and parous data. The formula suggested is a simple modification of the parous rate formula and is derived from the underlying population dynamics. This paper describes a field test of the proposed method.
Biochemical correlates of aortic distensibility in vivo in normal subjects.

1. Non-invasive aortic compliance measurements have been used previously to assess the distensibility of the aorta in several pathological conditions associated with increased cardiovascular risk. In adult patients with familial hypercholesterolaemia and those with growth hormone deficiency, aortic compliance has been found to correlate inversely with plasma cholesterol levels and age. We set out to establish if a relationship existed between the biophysical measurement of aortic compliance and biochemical variables in normal healthy adult subjects. 2. Blood pressure-corrected aortic distensibility, fasting insulin, insulin-like growth factor-I, total cholesterol, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol and triacylglycerol were measured in 38 (18 males, 20 females) normotensive healthy adults. 3. Blood pressure-corrected aortic distensibility was found to correlate inversely with age (r = -0.67, P < 0.001), low-density lipoprotein-cholesterol (r = -0.37, P < 0.02) and the low-density lipoprotein-/high density lipoprotein-cholesterol ratio (r = -0.33, P < 0.05) and positively with insulin-like growth factor-I (r = 0.47, P < 0.01). On separate analysis by sex, significant inverse correlations were observed in females between aortic distensibility and total cholesterol (r = -0.50, P < 0.02), low-density lipoprotein-cholesterol (r = -0.55, P < 0.01) and age (r = -0.74, P < 0.001). A positive correlation was found between aortic distensibility and insulin-like growth factor-I (r = 0.48, P < 0.05). On forced stepwise regression analysis, however, only age (P < 0.02) was found to be significant. In males, an inverse correlation was found between aortic distensibility and age (r = -0.57, P < 0.01), low-density lipoprotein-cholesterol (r = -0.51, P < 0.05), and the low-density lipoprotein-/high-density lipoprotein-cholesterol ratio (r = -0.63, P < 0.01).

Subjective determinants of attraction: Self-perceived causes of the rise and decline of liking, love, and being in love. Personal Relationships, 5(1), 91-104. Lee, J.A. (1973). The colors of love: An exploration of the ways of loving

Interest in the perceptions, expectations, behaviors, reactions, emotions and general functioning of couples has stimulated a great deal of psycho-social research in the past two decades in the West (e.g. Aron, Aron, & Smollan, 1992; Aronson, & Linder, 1965; Berscheid, & Walster, 1978; DíazLoving, 1996; Dion, & Dion, 1988; Freud, 1953; Fromm, 1956; Gurung, Sarason, & Sarason, 1997; Heider, 1958; Lamm, Weismann, & Keller, 1998; Rubin, 1973; Shaver, Hazan, & Bradshaw, 1987; Sternberg, 1986). However, research has either been empirically and question driven leaving little space for theoretical models or has been primarily based on intuitive and partial approaches that are not adequate to integrate findings and guide future research. In an attempt to describe the interrelationships of these phenomena among Mexican couples, an empirical structural model, which integrates variables in an ordered and logical fashion, is presented. Based on Díaz-Loving and Sánchez Aragón (2002), a bio-psycho-socio-cultural model was considered to select variables and measures. The first step included the conceptualization and development of valid, reliable and culturally sensitive measures of each construct. At a second stage, the created items were enriched with Mexican inventories of jealousy, couple interaction, and marital satisfaction. The research project was undertaken with 459 Mexico City middle, and lower socio-economic class couples who filled out the extensive self-report questionnaire. The inventory included a section of socio-demographic questions such as sex, age, education, lenght of the relationship, etc. and Díaz-Loving INTERDISCIPLINARIA, 2004, 21,1, 53-70 54 CONFIGURATION AND INTEGRATION OF PSYCHOSOCIAL COMPONENTS IN MEXICAN COUPLE RELATIONS Rolando Díaz-Loving *
