This study examines the conditions under which 3-year-olds can use the desires of others to predict others' behavior. In Study 1, children were highly successful in predicting the actions of an agent based on that agent's desires when they were explicitly told about the agent's desires, even when the agent's desires were strongly different from…

Conception, fabrication et validation d'une presse a injection basse pression pour le procede des poudres metalliques =

NASA Astrophysics Data System (ADS)

Lamarre, Simon G.

Le moulage par injection a basse pression de poudre metallique est une technique de mise en forme de pieces de formes complexes. La poudre metallique est melangee avec des polymeres basse viscosite (ex. : cire) pour former un melange homogene a une temperature superieure a la temperature de fusion des polymeres. Pour faciliter l'injection dans la cavite du moule, la composition des melanges est ajustee pour diminuer la viscosite. D'une part, les melanges peu visqueux possedent une bonne moulabilite. D'autre part, le phenomene de la segregation se manifeste rapidement avec les melanges peu visqueux. Les machines commerciales sont munies d'un canal d'injection et d'une valve qui relient le reservoir de melange et la cavite du moule. Le melange reste stationnaire dans ces composantes entre deux sequences d'injection, ce qui le rend propice a la segregation. Plusieurs brevets tentent de resoudre ce probleme en utilisant des pompes et des canaux de recirculation. Ces composantes sont difficiles a nettoyer en raison de leur complexite. Une machine a injection basse pression a ete concue et fabriquee pour l'etude de l'aptitude au moulage des melanges de tres faible viscosite (ex. : 0.1 Pa˙s), qui tient compte du phenomene de segregation et des contraintes de nettoyage. Un piston d'injection puise le volume desire d'un reservoir. Ensuite, un mouvement lateral cisaille le melange a l'intersection entre le reservoir et le cylindre et bouche l'orifice de sortie du reservoir. Le cylindre est degage et peut recevoir le moule. A la suite de l'injection, le piston retourne a la position du reservoir et entre dans son orifice de sortie. Le melange residuel est retourne dans le reservoir, melange et desaere a nouveau. L'appareil a ete valide par des essais d'injectabilite avec un melange de poudre d'acier inoxydable et de liants a basse viscosite. Des essais d'injection ont montre que le melange contenant l'acide stearique a parcouru la plus grande distance dans le moule de forme

Beginning in 2005, our team conducted a series of studies on optimal sexual experiences. We have applied our findings to develop a group therapy intervention for couples presenting with low sexual desire/frequency and sexual desire discrepancy. The goal was to improve the quality of erotic intimacy by focusing on such elements as being fully embodied during sex, increasing authenticity, trustworthiness, and vulnerability. Twenty-eight heterosexual individuals (14 couples) were seen in 16 hours of couples group therapy. Each completed the New Sexual Satisfaction Scale in pretests, posttests and six-month follow-ups. Significant differences in satisfaction (p <.001) were found in overall sample means from pretests to posttests and follow-ups. Significant differences were also found in 10 of 20 items, plus in two of three added items, including satisfaction with intensity of sexual arousal, variety, frequency, partner's initiation, and emotional opening up. Although this is a small sample, the results indicate that this intervention is effective. We interpret these findings in terms of creating just enough safety to enable couples to take erotic risks and thereby create desirable sexual intimacy.

Introduction La varicocèle est une pathologie masculine fréquente dont l'incidence est encore plus importante dans dans la population des hommes infertiles. Si ses mécanismes sont à ce jour incomplètement expliqués il semble acquis que la varicocèle peut être associée a une dysfonction testiculaire avec diminution du volume testiculaire et de la concentration en spermatozoïde de l’éjaculat. Méthodes Dans un premier temps nous exposons les résultats d'une étude rétrospective sur 5 ans (de Mars 2009 à Mars 2014), réalisée au service d'urologie A de l'hôpital Ibn Sina de Rabat et ayant comme objectif d’évaluer l'impact de la varicocèle palpable sur le volume testiculaire et les paramètres spermatiques. Tous les patients inclus dans notre étude avaient une varicocèle palpable. Dans un deuxième temps, et à travers une revue de la littérature nous discutons l'impact du traitement de la varicocèle sur la fertilité. Résultats 39 patients ont été inclus dans notre étude. L’âge moyen était de 29,71 ans et la varicocèle siégeait dans 89,74% des cas du coté gauche. Une atrophie testiculaire homolatérale à la varicocèle était retrouvée dans 7% des cas alors que des anomalies du spermogramme se voyaient dans 69,23% des cas. Conclusion L'impact de la varicocèle sur l'altération des paramètres spermatiques a été clairement établi bien que sa physio pathogénie ne soit pas bien élucidée. Le traitement chirurgical de la varicocèle semble indiqué chez les hommes infertiles présentant une varicocèle clinique et une altération significative du sperme. PMID:25918574

Beware of ligand efficiency (LE): understanding LE data in modeling structure-activity and structure-economy relationships.

Polanski, Jaroslaw; Tkocz, Aleksandra; Kucia, Urszula

2017-09-11

On the one hand, ligand efficiency (LE) and the binding efficiency index (BEI), which are binding properties (B) averaged versus the heavy atom count (HAC: LE) or molecular weight (MW: BEI), have recently been declared a novel universal tool for drug design. On the other hand, questions have been raised about the mathematical validity of the LE approach. In fact, neither the critics nor the advocates are precise enough to provide a generally understandable and accepted chemistry of the LE metrics. In particular, this refers to the puzzle of the LE trends for small and large molecules. In this paper, we explain the chemistry and mathematics of the LE type of data. Because LE is a weight metrics related to binding per gram, its hyperbolic decrease with an increasing number of heavy atoms can be easily understood by its 1/MW dependency. Accordingly, we analyzed how this influences the LE trends for ligand-target binding, economic big data or molecular descriptor data. In particular, we compared the trends for the thermodynamic ∆G data of a series of ligands that interact with 14 different target classes, which were extracted from the BindingDB database with the market prices of a commercial compound library of ca. 2.5 mln synthetic building blocks. An interpretation of LE and BEI that clearly explains the observed trends for these parameters are presented here for the first time. Accordingly, we show that the main misunderstanding of the chemical meaning of the BEI and LE parameters is their interpretation as molecular descriptors that are connected with a single molecule, while binding is a statistical effect in which a population of ligands limits the formation of ligand-receptor complexes. Therefore, LE (BEI) should not be interpreted as a molecular (physicochemical) descriptor that is connected with a single molecule but as a property (binding per gram). Accordingly, the puzzle of the surprising behavior of LE is explained by the 1/MW dependency. This effect

Two experiments examined whether 5-year-olds draw inferences about desire outcomes that constrain their online interpretation of an utterance. Children were informed of a speaker's positive (Experiment 1) or negative (Experiment 2) desire to receive a specific toy as a gift before hearing a referentially ambiguous statement ("That's my present") spoken with either a happy or sad voice. After hearing the speaker express a positive desire, children (N=24) showed an implicit (i.e., eye gaze) and explicit ability to predict reference to the desired object when the speaker sounded happy, but they showed only implicit consideration of the alternate object when the speaker sounded sad. After hearing the speaker express a negative desire, children (N=24) used only happy prosodic cues to predict the intended referent of the statement. Taken together, the findings indicate that the efficiency with which 5-year-olds integrate desire reasoning with language processing depends on the emotional valence of the speaker's voice but not on the type of desire representations (i.e., positive vs. negative) that children must reason about online.

Hypoactive sexual desire disorder (HSDD) is hypothesized to be a disorder of the brain's reward circuitry. Neurotransmitters in reward circuits are thus therapeutic targets for improving sexual desire. Novel treatment strategies are to enhance dopamine (DA) actions, reduce serotonin (5-HT) actions, or both. (c) Copyright 2010 Physicians Postgraduate Press, Inc.

The investigation by Z.-Q Zhang et al. (Acta Optica Sinica 11, 193, 1991) shows that it is possible to realize soft X-ray lasing in the water window 23.3-43.8 [Angstrom] with the Na-like recombination scheme, which requires a lower pumping power at a high-power laser facility than that with other schemes. The fine-structure levels with n [le] 15 and l [le] 6 in Na-like ions with 38 [le] Z [le] 45 and the probabilities for radiative transitions between these levels are calculated using the multiconfiguration Dirac-Fock approach. The calculations show that the wavelengths of the anticipated laser transitions 6 f-4d andmore » 6g-4f in the Na-like ions with 38 [le] Z [le] 43 and 5f-4d and 5g-4f in the Na-like ions with 40 [le] Z [le] 45 lie in the region of the water window.« less

Biomechanical considerations for distraction of the monobloc, Le Fort III, and Le Fort I segments.

Figueroa, Alvaro A; Polley, John W; Figueroa, Aaron D

Distraction osteogenesis is effective for correction of severe maxillary and midface hypoplasia. The vectors controlling the segment to be moved must be planned. This requires knowledge of the physical characteristics of the osteotomized bone segment, including the location of the center of mass (free body) and the center of resistance (restrained body). The purpose of this study was to determine the center of mass of the osteotomized monobloc, Le Fort III, and Le Fort I bone segments. A dry human skull was used to sequentially isolate three bone segments: monobloc, Le Fort III, and Le Fort I. Each segment was suspended from three different points, and digital photographs were obtained from each suspension. The photographs were digitally superimposed. The center of mass was determined by calculating the intersection of the suspension lines. The center of mass for the monobloc segment was located at a point 43.5 percent of the total height from the occlusal plane to the superior edge of the frontal bone supraorbital osteotomy. For the Le Fort III, it was located 38 percent of the total height from the occlusal plane to the superior edge of the osteotomized base of the nasal bones. For the Le Fort I, it was 53 percent of the total height from the occlusal plane to the superior edge of the osteotomized maxillary bone. Knowledge of the location of the center of mass in the monobloc, Le Fort III, and Le Fort I segments provides a starting point for the clinician when planning vectors for advancement with distraction.

Object of desire self-consciousness theory.

Bogaert, Anthony F; Brotto, Lori A

2014-01-01

In this article, the authors discuss the construct of object of desire self-consciousness, the perception that one is romantically and sexually desirable in another's eyes. The authors discuss the nature of the construct, variations in its expression, and how it may function as part of a self-schemata or script related to romance and sexuality. The authors suggest that object of desire self-consciousness may be an adaptive, evolved psychological mechanism allowing sexual and romantic tactics suitable to one's mate value. The authors also suggest that it can act as a signal that one has high mate value in the sexual marketplace. The authors then review literature (e.g., on fantasies, on sexual activity preferences, on sexual dysfunctions, on language) suggesting that object of desire self-consciousness plays a particularly important role in heterosexual women's sexual/romantic functioning and desires.

Desire thinking as a predictor of gambling.

Desire thinking is a voluntary cognitive process involving verbal and imaginal elaboration of a desired target. A desired target can relate to an object, an internal state or an activity, such as gambling. This study investigated the role of desire thinking in gambling in a cohort of participants recruited from community and clinical settings. Ninety five individuals completed a battery of self-report measures consisting of the Hospital Anxiety and Depression Scale (HADS), the Gambling Craving Scale (GCS), the Desire Thinking Questionnaire (DTQ) and the South Oaks Gambling Screen (SOGS). Correlation analyses revealed that gender, educational level, recruitment source, anxiety and depression, craving and desire thinking were correlated with gambling. A hierarchical multiple regression analysis revealed that both recruitment source and desire thinking were the only independent predictors of gambling when controlling for all other study variables, including craving. These findings are discussed in the light of metacognitive therapy (MCT). Copyright © 2014 Elsevier Ltd. All rights reserved.

Absolute dating of planetary samples is an essential tool to establish the chronology of geological events, including crystallization history, magmatic evolution, and alteration. Traditionally, geochronology has only been accomplishable on samples from dedicated sample return missions or meteorites. The capability for in situ geochronology is highly desired, because it will allow one-way planetary missions to perform dating of large numbers of samples. The success of an in situ geochronology package will not only yield data on absolute ages, but can also complement sample return missions by identifying the most interesting rocks to cache and/or return to Earth. In situ dating instruments have been proposed, but none have yet reached TRL 6 because the required high-resolution isotopic measurements are very challenging. Our team is now addressing this challenge by developing the Potassium (K) - Argon Laser Experiment (KArLE) under the NASA Planetary Instrument Definition and Development Program (PIDDP), building on previous work to develop a K-Ar in situ instrument [1]. KArLE uses a combination of several flight-proven components that enable accurate K-Ar isochron dating of planetary rocks. KArLE will ablate a rock sample, determine the K in the plasma state using laser-induced breakdown spectroscopy (LIBS), measure the liberated Ar using quadrupole mass spectrometry (QMS), and relate the two by the volume of the ablated pit using an optical method such as a vertical scanning interferometer (VSI). Our preliminary work indicates that the KArLE instrument will be capable of determining the age of several kinds of planetary samples to +/-100 Myr, sufficient to address a wide range of geochronology problems in planetary science.

Le continu contre l'espace

NASA Astrophysics Data System (ADS)

Salanskis, Jean-Michel

Disons pour conclure que, en tout état de cause, la façon de concevoir philosophiquement le conflit du continu et de l'espace que nous avons trouvée chez Hegel n'est pas homogène avec le style et les modalités de la pensée mathématique: 1) d'une part, le lien classique, le lien de référence entre continu et espace en mathématiques n'est pas que l'espace serait premier et privé de pensée, et le continu second, venant dissoudre l'espace en apportant la qualité, l'infini et la pensée, mais tout au contraire, il consiste en ce que l'espace est fondé sur l'abîme infinitaire du continu ; 2) d'autre part, l'éventuel divorce entre l'espace et le continu dans l'aire mathématique n'est pas celui d'une réflexivité purement conceptuelle du continu avec un positivisme géométrique, n'équivaut pas à une rupture disciplinaire ; il est plutôt le symptôme de la dérive d'une herméneutique à l'égard d'une autre, au sein d'un continent juridique commun définissant la discipline (la mathématique ensembliste), cette dérive pouvant, à la limite, induire une refonte de ce sol juridique, sans que jamais il soit question pour autant de nier l'unité des mathématiques, à comprendre ici comme l'unité ultime de responsabilité de la communauté mathématique à l'égard des trois questions Qu'est-ce que l'espace?”, “Qu'est-ce que le continu?” et “Qu'est-ce que l'infini?”.

Desired lifetime and end-of-life desires across adulthood from 20 to 90: a dual-source information model.

PubMed

Lang, Frieder R; Baltes, Paul B; Wagner, Gert G

2007-09-01

How long do people want to live, and how does scientific research on aging affect such desires? A dual-source information model proposes that aging expectations and desires are informed differently by two sources: personal experiences on the one hand, and scientific and societal influences on the other. Two studies with independent German national samples explored desires regarding length of life and end of life among adults between the ages of 20 and 90. FINDINGS ARE: First, desired lifetime is consistent at around 85 years with few age differences. Second, experimental induction of good or bad news from research on aging has little effect in Study 1. Third, interest in science has moderating effects on desired lifetime in Study 2. Fourth, there is a high prevalence of a strong desire to control the "when and how" of one's death, although only 11% of the individuals completed a living will. Findings are consistent with the dual-source information model.

2006-01-01

CONTEXTE : Un nouveau traitement anti-immunoglobuline E (anti-IgE) contre l’asthme, l’omalizumab, a été approuvé au Canada. OBJECTIF : Passer en revue les données fondamentales et cliniques sur l’omalizumab et examiner le rôle possible de ce médicament dans la prise en charge de l’asthme au Canada. MÉTHODOLOGIE : Une recherche documentaire a été effectuée dans MEDLINE afin de repérer les études menées de 1960 à 2006 sur l’omalizumab. La recherche a également porté sur les résumés de réunions scientifiques récentes dans le domaine des maladies respiratoires et des allergies; par ailleurs, toute donnée non publiée a été demandée au fabricant. Après avoir revu et résumé les données, un comité mixte constitué de spécialistes des maladies respiratoires et des allergies a rédigé un ensemble de recommandations relatives à l’utilisation de l’omalizumab. RÉSULTATS : L’omalizumab est un anticorps monoclonal humanisé qui se lie au domaine C epsilon 3 de la molécule d’IgE pour former des complexes immuns solubles qui sont éliminés par le système réticulo-endothélial. L’administration d’injections sous-cutanées espacées de deux ou de quatre semaines à la dose recommandée entraîne une diminution rapide des taux d’IgE circulantes libres. Lors de deux essais cliniques de phase III menés auprès de 1 405 adultes et adolescents atteints d’asthme modéré à grave qui recevaient des doses moyennes stables de corticostéroïdes en inhalation (CSI), l’omalizumab a diminué les taux d’exacerbation par rapport au placebo et a été associé à une amélioration des symptômes ainsi qu’à une épargne plus importante des corticostéroïdes. Dans un essai mené auprès de 419 patients atteints d’asthme grave non maîtrisé malgré l’utilisation de doses élevées de CSI et de la prise concomitante d’agonistes bêta-2 à action prolongée, les exacerbations graves étaient de 50 % moins fréquentes chez

Implicit theories of a desire for fame.

The aim of the present studies was to generate implicit theories of a desire for fame among the general population. In Study 1, we were able to develop a nine-factor analytic model of conceptions of the desire to be famous that initially comprised nine separate factors; ambition, meaning derived through comparison with others, psychologically vulnerable, attention seeking, conceitedness, social access, altruistic, positive affect, and glamour. Analysis that sought to examine replicability among these factors suggested that three factors (altruistic, positive affect, and glamour) neither display factor congruence nor display adequate internal reliability. A second study examined the validity of these factors in predicting profiles of individuals who may desire fame. The findings from this study suggested that two of the nine factors (positive affect and altruism) could not be considered strong factors within the model. Overall, the findings suggest that implicit theories of a desire for fame comprise six factors. The discussion focuses on how an implicit model of a desire for fame might progress into formal theories of a desire for fame.

Hungry for money: the desire for caloric resources increases the desire for financial resources and vice versa.

This report attempts to provide an evolutionary explanation for humans' motivation to strive for money in present-day societies. We propose that people's desire for money is a modern derivate of their desire for food. In three studies, we show the reciprocal association between the incentive value of food and of money. In Study 1, hungry participants were less likely than satiated participants to donate to charity. In Study 2, participants in a room with an olfactory food cue, known to increase the desire to eat, offered less money in a give-some game compared with participants in a room free of scent. In Study 3, participants' desire for money affected the amount of M&M's they ate in a subsequent taste test, but only among participants who were not restricting their food intake in order to manage their weight.

Rational desires and the limitation of life-sustaining treatment.

PubMed

Savulescu, Julian

1994-07-01

It is accepted that treatment of previously competent, now incompetent patients can be limited if that is what the patient would desire, if she were now competent. Expressed past preferences or an advance directive are often taken to constitute sufficient evidence of what a patient would now desire. I distinguish between desires and rational desires. I argue that for a desire to be an expression of a person's autonomy, it must be or satisfy that person's rational desires. A person rationally desires a course of action if that person desires it while being in possession of all available relevant facts, without committing relevant error of logic, and "vividly imagining" what its consequences would be like for her. I argue that some competent, expressed desires obstruct autonomy. I show that several psychological mechanisms operate to prevent a person rationally evaluating what future life in a disabled state would be like. Rational evaluation is difficult. However, treatment limitation, if it is to respect autonomy, must be in accord with a patient's rational desires, and not merely her expressed desires. I illustrate the implications of these arguments for the use of advance directives and for the treatment of competent patients.

A Desire for Social Media Is Associated With a Desire for Solitary but Not Social Activities.

PubMed

Hill, Lauren; Zheng, Zane

2017-01-01

While social media is an aspect of life for many, it brings to light the lack of interpersonal connection when browsing activity occurs. The displacement theory suggests that the quality of one's offline interactions is affected by how much time an individual allots to those exchanges. Depending on the amount of time spent online, interpersonal connections may suffer and lead to negative psychological consequences. Our study aimed to explore the relationship between the desirability of social media and socialization preferences through a cue-based perceptual judgment task where participants ( N = 136) rated 40 gray-scale images in terms of their desirability. The image categories included social media icons, singular scenes depicting an isolated activity, social scenes representing an interactive activity, and traffic signs as the control. We also included questionnaires to assess depressiveness and aspects of social media usage. Our findings suggest that the immediate desire for social media is potentially linked to one's desire for social isolation as represented by the singular scene category, the intensity of participant's reported daily usage, and the extent to which social media is perceived to impact real social life. To our knowledge, this is the first report on the initial desirability judgment of social media and its association with other factors. Further research is needed to distinguish the variability in users' aim of using social media and if that is related to one's perceived feelings of social connectedness and solitude.

Simultaneous transgenic suppression of LePG and LeExp1 influences fruit texture and juice viscosity in a fresh market tomato variety.

PubMed

Powell, Ann L T; Kalamaki, Mary S; Kurien, Philip A; Gurrieri, Sergio; Bennett, Alan B

2003-12-03

Tomatoes are grown for fresh consumption or for processing of the fruit. Some ripening-associated processes of the fruit can either contribute to or degrade attributes associated with both fresh and processing quality. For example, cell wall disassembly is associated with loss of fresh fruit firmness as well as with loss of processed tomato product viscosity. Several enzymes contribute to cell wall polysaccharide disassembly. Polygalacturonase (PG, poly[1,4-alpha-d-galactouronide] glucanohydrolase, EC 3.2.1.15) is among the most abundant polysaccharide hydrolases in ripening tomato fruit and is the major contributor to pectin depolymerization. Expansin (LeExp1) is also abundant in ripening fruit and is proposed to contribute to cell wall disassembly by nonhydrolytic activity, possibly by increasing substrate accessibility to other enzymes. Suppression of either LePG or LeExp1 expression alone results in altered softening and/or shelf life characteristics. To test whether simultaneous suppression of both LePG and LeExp1 expression influences fruit texture in additive or synergistic ways, transgenic Lycopersicon esculentum var. Ailsa Craig lines with reduced expression of either LePG or LeExp1 were crossed. Fruits from the third generation of progeny, homozygous for both transgenic constructs, were analyzed for firmness and other quality traits during ripening on or off the vine. In field-grown transgenic tomato fruit, suppression of LeExp1 or LePG alone did not significantly increase fruit firmness. However, fruits suppressed for both LePG and LeExp1 expression were significantly firmer throughout ripening and were less susceptible to deterioration during long-term storage. Juice prepared from the transgenic tomato fruit with reduced LePG and LeExp1 expression was more viscous than juice prepared from control fruit.

A compelling desire for deafness.

PubMed

Veale, David

2006-01-01

A case is described of a patient who has a compelling and persistent desire to become deaf. She often kept cotton wool moistened with oil in her ears and was learning sign language. Living without sound appeared to be a severe form of avoidance behavior from hyperacusis and misophonia. She had a borderline personality disorder that was associated with a poor sense of self. Her desire to be deaf may be one aspect of gaining an identity for herself and to compensate for feeling like an alien and gaining acceptance in the Deaf community. Will a compelling desire for deafness ever become a recognized mental disorder one day for which hearing patients may be offered elective deafness after a period of assessment and living like a deaf person? Those working in the field of deafness should be aware that individuals may occasionally be seeking elective deafness or self-inflicting deafness to obtain a hearing aid.

Le Laser A Argon Ionise : Applications Therapeutiques

Le laser a argon ionise est un laser a emission continue, reglee en general en multiraies de 487 a 544 nm. Le rayonnement de ce laser est bien absorbe par les tissus vivants, avec une action preferentielle au niveau des pigments rouges (hemoglobine, myoglobine) et noirs (melanine). Le laser a argon est princi-palement utilise en therapeutique pour ses effets thermiques : en fonction du choix des parametres (puissance optique, surface exposee, temps d'exposition) on peut obtenir une coagulation (temperature optimale au niveau des tissus 60° - 80°) ou une volatisation (temperature superieure a 100°). Si la zone volatilisee est tres etroite (inferieure a 0,5 mm) on obtient un effet de coupe. Par rapport aux deux autres lasers egalement utilises pour leurs effets thermiques (CO2 et Nd. YAG) l'argon a des effets intermediaires : la coagulation sera plus superficielle qu'avec le Nd. YAG et la volatisation plus profonde qu'avec le CO2. Lors de la coupe, la necrose sur les berges sera egalement plus importante qu'avec le CO2.

Testosterone and sexual desire in healthy women and men.

PubMed

van Anders, Sari M

2012-12-01

Sexual desire is typically higher in men than in women, with testosterone (T) thought to account for this difference as well as within-sex variation in desire in both women and men. However, few studies have incorporated both hormonal and social or psychological factors in studies of sexual desire. The present study addressed how three psychological domains (sexual-relational, stress-mood, body-embodiment) were related to links between T and sexual desire in healthy adults and whether dyadic and solitary desire showed associations with T. Participants (n = 196) were recruited as part of the Partnering, Physiology, and Health study, which had 105 men and 91 women who completed questionnaires and provided saliva for cortisol and T assays. T was positively linked to solitary desire in women, with masturbation frequency influencing this link. In contrast, T was negatively correlated with dyadic desire in women, but only when cortisol and perceived social stress were controlled. Replicating past findings, no significant correlations between T and desire in men were apparent, but these analyses showed that the null association remained even when psychological and confound variables were controlled. Men showed higher desire than women, but masturbation frequency rather than T influenced this difference. Results were discussed in terms of challenges to assumptions of clear links between T and desire, gendered approaches to T, and the unitarity of desire.

Le Fort Fractures: A Collective Review

Le Fort fractures constitute a pattern of complex facial injury that occurs secondary to blunt facial trauma.  The most common mechanisms of injury for these fractures, which are frequently associated with drug and alcohol use, include motor vehicle collisions, assault, and falls. A thorough search of the world’s literature following PRISMA guidelines was conducted through PubMed and EBSCO databases. Search terms included “Le Fort fracture”, “facial”, “craniofacial”, and “intracranial.”  Articles were selected based on relevance and examined regarding etiology, epidemiology, diagnosis, treatment, complications, and outcomes in adults. The analyzed studies were published between 1980 and 2016. Initial data search yielded 186 results. The search was narrowed to exclude articles lacking in specificity for Le Fort fractures.  Fifty-one articles were selected, the majority of which were large case studies, and collectively reported that Le Fort fractures are most commonly due to high-velocity MVC and that the severity of fracture type sustained occurred with increasing frequency.  It was also found that there is a general lack of published Level I, Level II, and Level III studies regarding Le Fort fracture management, surgical management, and outcomes. The limitation of this study, similar to all PRISMA-guided review articles, is the dependence on previously published research and availability of references as outlined in our methodology. While mortality rates for Le Fort fractures are low, these complex injuries seldom occur in isolation and are associated with other severe injuries to the head and neck. Quick and accurate diagnosis of Le Fort fractures and associated injuries is crucial to the successful management of blunt head trauma. PMID:29177168

Desire thinking: what is it and what drives it?

PubMed

Caselli, Gabriele; Spada, Marcantonio M

2015-05-01

The aim of this study was to provide an overview of the construct of desire thinking and test a metacognitive model of desire thinking and craving, based on the work of Spada, Caselli and Wells (2012; 2013), which aims to explain the perseveration of desire thinking. We conducted two studies involving four clinical samples (total N = 493) and a community sample (N = 494) presenting with different addictive behaviors. The relationships among variables were examined by testing the fit of path models within each sample. In the model presented it was proposed that positive metacognitions about desire thinking are associated with, in turn, imaginal prefiguration and verbal perseveration, marking the activation of desire thinking. Verbal perseveration is then associated to negative metacognitions about desire thinking and craving denoting the pathological escalation of desire thinking. Finally, a direct association between positive metacognitions about desire thinking and negative metacognitions about desire thinking would mark those occasions where target-achieving behaviour runs as an automatized schemata without the experience of craving. Results indicated a good model fit in the clinical sample and a variation in the model structure in the community sample. These findings provide further support for the application of metacognitive theory to desire thinking and craving in addictive behaviors. Copyright © 2014 Elsevier Ltd. All rights reserved.

Le syndrome d’alcoolisme foetal

PubMed Central

2002-01-01

L’alcool est un tératogène physique et comportemental. Le syndrome d’alcoolisme foetal (SAF) est un trouble courant mais encore sous-diagnostiqué découlant de la consommation d’alcool par la mère pendant la grossesse. Bien qu’il puisse être prévenu, le SAF est également invalidant. Même si le SAF est présent dans tous les groupes socioéconomiques du Canada, sa prévalence est élevée dans certaines communautés inuites et des Premières nations du Canada. Le présent énoncé porte sur la prévention, le diagnostic, le dépistage précoce et la prise en charge du SAF par les professionnels de la santé. La prévention du SAF doit s’effectuer à deux échelons. La prévention primaire consiste à éliminer le SAF par une formation en classe ou dans la collectivité et à inciter les femmes à éviter de consommer de l’alcool avant la conception et pendant la grossesse. La prévention secondaire consiste à repérer les femmes qui boivent pendant leur grossesse et à réduire leur consommation. Le présent énoncé décrit plusieurs stratégies de dépistage, dont la stratégie T-ACE (tolérance-agacement, réduction, éveil). Les dispensateurs de soins devraient recommander l’abstinence dès la première visite prénatale. Un envoi rapide en consultation en vue de traiter l’alcoolisme est recommandé pour les femmes enceintes incapables d’arrêter de boire. Le présent énoncé décrit le diagnostic de SAF, de SAF partiel ou atypique, d’anomalies congénitales et de troubles neurodéveloppementaux reliés à l’alcool. En cas d’exposition à l’alcool in utero, un diagnostic de SAF devrait être envisagé en présence d’un retard de croissance courant ou antérieur, de certaines anomalies faciales touchant la lèvre supérieure et les yeux et d’anomalies neurodéveloppementales. Ces caractéristiques sont mieux quantifiées au moyen d’une méthode diagnostique à quatre chiffres. Des stratégies de dépistage précoce des

Cues Resulting in Desire for Sexual Activity in Women

PubMed Central

McCall, Katie; Meston, Cindy

2010-01-01

Introduction A number of questionnaires have been created to assess levels of sexual desire in women, but to our knowledge, there are currently no validated measures for assessing cues that result in sexual desire. A questionnaire of this nature could be useful for both clinicians and researchers, because it considers the contextual nature of sexual desire and it draws attention to individual differences in factors that can contribute to sexual desire. Aim The aim of the present study was to create a multidimensional assessment tool of cues for sexual desire in women that is validated in women with and without hypoactive sexual desire disorder (HSDD). Methods Factor analyses conducted on both an initial sample (N = 874) and a community sample (N = 138) resulted in the Cues for Sexual Desire Scale (CSDS) which included four factors: (i) Emotional Bonding Cues; (ii) Erotic/ Explicit Cues; (iii) Visual/Proximity Cues; and (iv) Implicit/Romantic Cues. Main Outcome Measures Scale construction of cues associated with sexual desire and differences between women with and without sexual dysfunction. Results The CSDS demonstrated good reliability and validity and was able to detect significant differences between women with and without HSDD. Results from regression analyses indicated that both marital status and level of sexual functioning predicted scores on the CSDS. The CSDS provided predictive validity for the Female Sexual Function Index desire and arousal domain scores, and increased cues were related to a higher reported frequency of sexual activity in women. Conclusions The findings from the present study provide valuable information regarding both internal and external triggers that can result in sexual desire for women. We believe that the CSDS could be beneficial in therapeutic settings to help identify cues that do and do not facilitate sexual desire in women with clinically diagnosed desire difficulties.

RÉSUMÉ La transmission des infections au cabinet du pédiatre est de plus en plus préoccupante. Le présent document expose les voies de transmission des infections et les principes sous-jacents aux mesures actuelles pour contrôler les infections. Pour prévenir les infections, il faut bien concevoir le cabinet et adopter des politiques administratives et de triage convenables, de même que des pratiques de base pour les soins de tous les patients (p. ex., hygiène des mains, port de gants, de masques, de lunettes de protection et d’une blouse d’hôpital pour des interventions précises; nettoyage, désinfection et stérilisation convenables des surfaces et du matériel, y compris les jouets, et techniques d’asepsie en cas d’interventions effractives) et des précautions additionnelles en cas d’infections précises. Le personnel doit avoir reçu les vaccins pertinents, et les personnes infectées doivent respecter les politiques de restriction au travail.

Toute maladie est un mal en soi qu’il faut éradiquer car elle altère souvent de façon significative la qualité de la vie. L’hystérectomie vaginale est indiquée pour les patientes qui présentent certaines affections gynécologiques graves, elle est donc bénéfique mais, peut également avoir une répercussion néfaste sur la qualité de vie de la femme. Ainsi nous avons voulu explorer le vécu de la maladie et de l’hystérectomie vaginale (HV) des femmes avant et après l’intervention chirurgicale. Nous avons effectué une étude prospective qualitative, à recueil clinique sur une période de 12 mois; qui a concerné les femmes, ayant subi une hystérectomie vaginale. Celles n’ayant pas accepté de participer à l’étude, ou n’ayant pas de contact téléphonique n’ont pas été incluses. Pendant la maladie, le vécu des femmes a été: l’inconfort sexuel 26/40 (65%); les saignements génitaux 12/40 (30%); les douleurs pelviennes 13/40 (32,5%). En Post-opératoire, ont été noté les dyspareunies transitoires30/40 (75%) ; les céphalées secondaires à l’anesthésie 4/40 (10%). Le vécu psychologique a été dominé avant l’HV par la peur de la chirurgie chez toutes les patientes, les troubles du sommeil 38/40 (95%), l’angoisse 30 /40(75%), un sentiment de honte lié aux difficultés à accomplir l’acte sexuel en raison du prolapsus 26/40(65%) et/ ou en raison des saignements génitaux, dus au fibrome utérin 14/40(35%). Le sentiment de la perte de féminité était déclaré par 26/40 femmes porteuses de prolapsus utérin (65%), la modification de l’estime de soi 26/40 (65%). Ces appréciations subjectives ont été améliorées avec l’HV, contre balançant la perte de leur organe de reproduction. Aucune information n’a été donnée par les femmes à leurs proches et aux membres de la famille avant la chirurgie, traduisant ainsi leur sentiment de gène ou de honte. L’arrêt des symptômes a été observé dans tous les

Dans le mémoire qui suit, les ordres structural, magnétiques et orbital dans le YVO3 sont étudiés avec l'aide de la diffraction des rayons X,de la spectroscopie Raman et de la technique de la cavité résonnante hyperfréquence. L'objectif premier consiste à observer l'évolution de ces ordres en fonction de la température. Le mémoire met ensuite en évidence le couplage entre les différents ordres cohabitants dans le YVO3 . Les mesures effectuées par la diffraction des rayons X permettent de mesurer le caractère polycrystallin des échantillons du YVO 3. Une comparaison de nos mesures avec des mesures de diffraction des rayons X faites sur la poudre de YVO3 indique la faible présence de maclage. Les mesures effectuées avec la technique de résonnance hyperfréquence permettent de suivre l'évolution de la constante diélectrique en fonction de la température. Les changements impliquant l'ordre orbital se manifestent de manière évidente dans la constante diélectrique à 200 K et à 77 K. La transition diélectrique détectée à 77 K est une transition de premier ordre. Un couplage entre les propriétés diélectriques et magnétiques est observable à la température de Néel à 114 K. L'effet d'un champ magnétique fixe sur la température de transition de l'ordre orbital survenant à 77 K est également remarquable. Cela indique un couplage magnétodiélectrique démontrant ainsi le caractère multiferroïque du YVO 3. Finalement, l'observation d'un mécanisme de relaxation pouvant être modélisé par le modèle d'Havriliak-Negami est observé en dessous de 77 K. En utilisant le modèle d'Arrhénius et le modèle d'Havriliak-Negami, on peut caractériser le mécanisme avec son énergie d'activation et son temps de relaxation. Les mesures effectuées en spectroscopie Raman permettent de suivre l'évolution de la structure du YVO3 en fonction de la température. Les deux changements structuraux survenant à 200 K et 77 K sont observés. Le

Children's understanding of the distinction between intentions and desires.

PubMed

Schult, Carolyn A

2002-01-01

Much of the previous research on children's understanding of intentions confounded intentions with desires. Intentions and desires are different, in that a desire can be satisfied in a number of ways, but an intention must be satisfied by carrying out the intended action. Children 3 through 7 years of age and adults were presented with situations in which intentions were satisfied but desires were not, or vice versa, in a story-comprehension task (N = 71) and a target-hitting game (N = 45). Although 3- and 4-year-olds were unable to differentiate desires and intentions consistently, 5- and 7-year-olds often matched the adult pattern. Younger children's difficulties in understanding intentions are discussed in terms of their use of a desire-outcome matching strategy and the representational complexities of intentions.

Desirable Difficulties in Vocabulary Learning

BJORK, ROBERT A.; KROLL, JUDITH F.

2016-01-01

In this article we discuss the role of desirable difficulties in vocabulary learning from two perspectives, one having to do with identifying conditions of learning that impose initial challenges to the learner but then benefit later retention and transfer, and the other having to do with the role of certain difficulties that are intrinsic to language processes, are engaged during word learning, and reflect how language is understood and produced. From each perspective we discuss evidence that supports the notion that difficulties in learning and imposed costs to language processing may produce benefits because they are likely to increase conceptual understanding. We then consider the consequences of these processes for actual second-language learning and suggest that some of the domain-general cognitive advantages that have been reported for proficient bilinguals may reflect difficulties imposed by the learning process, and by the requirement to negotiate cross-language competition, that are broadly desirable. As Alice Healy and her collaborators were perhaps the first to demonstrate, research on desirable difficulties in vocabulary and language learning holds the promise of bringing together research traditions on memory and language that have much to offer each other.

Predictors of sexual desire disorders in women.

Brotto, Lori A; Petkau, A John; Labrie, Fernand; Basson, Rosemary

2011-03-01

A historic belief was that testosterone was the "hormone of desire." However, recent data, which show either minimal or no significant correlation between testosterone levels and women's sexual desire, suggest that nonhormonal variables may play a key role. To compare women with hypoactive sexual desire disorder (HSDD) and those with the recently proposed more symptomatic desire disorder, Sexual Desire/Interest Disorder (SDID), on the relative contribution of hormonal vs. nonhormonal variables. Women with HSDD (N = 58, mean age 52.5) or SDID (N = 52, mean age 50.9) participated in a biopsychosocial assessment in which six nonhormonal domains were evaluated for the degree of involvement in the current low desire complaints. Participants provided a serum sample of hormones analyzed by gas chromatography-mass spectrometry or liquid chromatography/mass spectrometry/mass spectrometry. Logistic regression was used to assess the ability of variables (nonhormonal: history of sexual abuse, developmental history, psychosexual history, psychiatric status, medical history, and sexual/relationship-related factors; hormonal: dehydroepiandrosterone [DHEA], 5-diol, 4-dione, testosterone, 5-α-dihydrotestosterone, androsterone glucuronide, 3α-diol-3G, 3α-diol-17G, and DHEA-S; and demographic: age, relationship length) to predict group membership. Women with SDID had significantly lower sexual desire and arousal scores, but the groups did not differ on relationship satisfaction or mood. Addition of the hormonal variables to the two demographic variables (age, relationship length) did not significantly increase predictive capability. However, the addition of the six nonhormonal variables to these two sets of predictors significantly increased ability to predict group status. Developmental history, psychiatric history, and psychosexual history added significantly to the predictive capability provided by the basic model when examined individually. Nonhormonal variables added

Identity motives underlying desired and feared possible future selves.

2008-10-01

Desired and feared possible future selves are important motivators of behavior and provide a temporal context for self-evaluation. Yet little research has examined why people desire some possible selves and fear others. In two studies, we tested the reflection of identity motives for self-esteem, efficacy, meaning, continuity, belonging, and distinctiveness in people's desired and feared possible future selves and in their possible future identity structures. As predicted, participants desired especially those possible futures in which motives for self-esteem, efficacy, meaning, and continuity would be satisfied, and they feared especially those in which the same four motives and, marginally, the motive for distinctiveness would be frustrated. Analyses supported an indirect path from belonging via self-esteem to desire and fear. Desired and feared possible future selves reflect potential satisfaction and frustration of these identity motives.

Introduction L'objectif de ce travail était de déterminer la séroprévalence et les facteurs associés au VIH et aux hépatites virales B et C dans la ville de Bafoussam au Cameroun. Méthodes Il s'agissait d'une étude descriptive et analytique réalisée de février 2012 à Juin 2012 dans la ville de Bafoussam au Cameroun. Pour cette étude, nous avons obtenu une clairance éthique. Résultats Au total, 982 personnes ont été dépistées pour le VIH et les hépatites virales B et C. Les femmes représentaient 56,3% des personnes dépistées. La tranche d’âge la plus représentée était celle des 20 à 24 ans. L’âge médian était de 34,5 ans. Les prévalences du VIH, de l'AgHBs, et de l'Ac anti HCV étaient respectivement de 6,0%, 4,1%, et 0,4%. La prévalence du VIH était 2 fois plus élevée parmi les femmes que les hommes avec 8,1% contre 3,5% (p=0,01). Les prévalences les plus élevées ont été observées chez les personnes de 30 à 34 ans, 40 à 44 ans avec 15,0% et 11,5% (p=0,01), les personnes sans emploi avec 11,1% (p<0,001) et les personnes en union libre avec 17,9% (p=0,000). La prévalence du VIH n’était pas directement liée aux comportements et pratiques sexuels de la population de l’étude. On enregistrait une prévalence élevée de 29,3% chez les individus ayant déclaré avoir au moins une infection sexuellement transmissible (p=0,000). Conclusion Il apparait urgent de mettre en place des stratégies de prévention contre le VIH, les hépatites virales et les facteurs associés au Cameroun. PMID:26113899

Dans le Cap Bon tunisien, les particularités anatomopathologiques de ce cancer n'ont pas été précisées auparavant. Leur connaissance est nécessaire pour l'adaptation des systèmes de prévention et de soins dans la région. Le but de notre étude était de déterminer le profil anatomopathologique des carcinomes mammaires dans l'unique laboratoire d'anatomie pathologique publique de la région. Il s'agissait d'une étude descriptive rétrospective des carcinomes mammaires diagnostiqués chez 116 malades dans notre laboratoire sur une période de 5 ans de Juillet 2010 à Juillet 2015. Notre étude a inclus 116 patientes. L'âge moyen était de 51 ans. La taille tumorale histologique moyenne était de 31 mm. Le diagnostic initial était posé sur pièce de tumorectomie dans 83% des cas. Le carcinome infiltrant de type non spécifique était le type histologique le plus fréquent. Le grade SBR III était majoritaire. L'invasion lympho-vasculaire était présente dans 33% des cas. Le curage axillaire était positif dans 72% des cas. Les récepteurs hormonaux étaient positifs dans 73% des cas. Les récepteurs de l'Her2-Neu étaient surexprimés dans 19% des cas. Le ki67 était ≥ 14% dans 38%. Le sous-type moléculaire le plus fréquent était le luminal A. Le carcinome mammaire dans la région du Cap Bon se caractérise par sa survenue à un âge jeune, son importante taille tumorale et la fréquence de facteurs histopronostiques péjoratifs. PMID:28450990

Dysregulated sexuality and high sexual desire: distinct constructs?

PubMed

Winters, Jason; Christoff, Kalina; Gorzalka, Boris B

2010-10-01

The literature on dysregulated sexuality, whether theoretical, clinical or empirical, has failed to differentiate the construct from high sexual desire. In this study, we tested three hypotheses which addressed this issue. A sample of 6458 men and 7938 women, some of whom had sought treatment for sexual compulsivity, addiction or impulsivity, completed an online survey comprised of various sexuality measures. Men and women who reported having sought treatment scored significantly higher on measures of dysregulated sexuality and sexual desire. For men, women, and those who had sought treatment, dysregulated sexuality was associated with increased sexual desire. Confirmatory factor analysis supported a one-factor model, indicating that, in both male and female participants, dysregulated sexuality and sexual desire variables loaded onto a single underlying factor. The results of this study suggest that dysregulated sexuality, as currently conceptualized, labelled, and measured, may simply be a marker of high sexual desire and the distress associated with managing a high degree of sexual thoughts, feelings, and needs.

Asexuality: an extreme variant of sexual desire disorder?

PubMed

Brotto, Lori A; Yule, Morag A; Gorzalka, Boris B

2015-03-01

Human asexuality is defined as a lack of sexual attraction to anyone or anything. Various theories have been proposed to explain how asexuality should best be classified, and some have maintained that asexuality is an extreme variant of hypoactive sexual desire disorder (HSDD)-a sexual dysfunction characterized by a lack of interest in sex and significant distress. To date, this has never been empirically examined. Using measures of sexual desire and behavior, sex-related distress, personality, and psychopathology, the aim of the current study was to compare individuals scoring above the cutoff for asexuality identification (AIS >40) (n = 192) to sexual individuals (n = 231). The sexual group was further divided into a control group (n = 122), a HSDD group (n = 50), and a group with symptoms of low desire that were nondistressing (n = 59). Analyses were controlled for age. Individuals in the AIS >40 group had a greater likelihood of never previously engaging in sexual intercourse, fantasies, or kissing and petting than all other groups and a lower likelihood of experiencing sex-related distress than those with HSDD. For women, those in the HSDD and AIS >40 groups had significantly lower desire than the subclinical HSDD and control groups. Men in the AIS >40 group had significantly lower desire than the other three groups. Symptoms of depression were highest among those with subclinical HSDD and HSDD, whereas there were no group differences on alexithymia or desirable responding. A binary logistic regression indicated that relationship status (long-term dating/married), sexual desire, sex-related distress, and lower alexithymia scores were the best predictors of group membership (HSDD vs. AIS >40). Taken together, these results challenge the speculation that asexuality should be classified as a sexual dysfunction of low desire. © 2014 International Society for Sexual Medicine.

Self-forgetfulness is a facet of self-transcendence characterized by tendency to experience altered states of consciousness. We examined associations of self-forgetfulness with sexual desire and frequency. Two hundred sixty-one Portuguese men and women completed the self-forgetfulness subscale of the Temperament and Character Inventory-Revised, a measure of openness to experience, and a questionnaire on desired and actual frequency of vaginal intercourse, noncoital sex, and masturbation in the past month. In simple and partial correlations controlling for openness to experience and relationship status, women's self-forgetfulness correlated with desired frequency of intercourse and noncoital sex. For men, self-forgetfulness correlated with actual frequency of intercourse and noncoital sex.

Nitric oxide (NO) and mitogen-activated protein kinases (MAPKs) are signal molecules involved in the disease resistance of plants. To investigate the role of tomato MAPKs in the NO-mediated defense response, mature green tomatoes (Lycopersicon esculentum Mill. cv. Qian-xi) were treated with a MAPKs inhibitor (1,4-diamino-2,3-dicyano-1,4-bis(o-amino-phenylmercapto) butadiene (U0126)), NO donor sodium nitroprusside (SNP), and SNP plus U0126. Treatment with U0126 increased the incidence of disease and size of lesion areas in the tomato fruits after being inoculated with Botrytis cinerea. NO enhanced the resistance of the tomato fruits against Botrytis cinerea invasion and the activities of nitric oxide synthase, Chitinase, β-1,3-glucanase, polyphenol oxidase, and phenylalanine ammonia-lyase. However, the effects of NO on disease resistance were weakened by the MAPKs inhibitor. Meanwhile, the relative expression of LeMAPK1, LeMAPK2, and LeMAPK3 in the (SNP + U0126)-treated fruits was lower than that in the SNP-treated fruits. The results suggest that LeMAPK1/2/3 are involved in NO-induced disease resistance of tomato fruits against Botrytis cinerea.

Searching the animal psyche with Charles Le Brun.

PubMed

Cohen, Sarah R

2010-07-01

Around 1670 the French court painter and Academician Charles Le Brun produced a series of drawings featuring naturalistic animal heads, as well as imaginary heads in which he refashioned various nonhuman animal species to make humanoid physiognomies. What were the purpose and significance of these unusual works? I argue that they show Le Brun's interest in what we today would call animal psychology: focusing upon the sensory organs and their connections with the animal's brain, Le Brun studied his animals as conscious protagonists of the natural realm. One source that may have served him in this project was Marin Cureau de La Chambre's De la Connoissance des bestes of 1645, in which the physician argued that animals possess a conscious soul grounded in the senses. However, Le Brun's animal-humans have no clear place in the artist's taxonomy--nor, indeed, in any seventeenth-century understandings of species. It is rather John Locke, at his most skeptical, who offers the best parallel in the realm of natural philosophy to Le Brun's unsettling animal-humans. Probably without meaning to, Le Brun demonstrated through his eerie, boundary-crossing creatures the limits of visual classification.

Wishful seeing: more desired objects are seen as closer.

PubMed

Balcetis, Emily; Dunning, David

2010-01-01

Although people assume that they see the surrounding environment as it truly is, we suggest that perception of the natural environment is dependent upon the internal goal states of perceivers. Five experiments demonstrated that perceivers tend to see desirable objects (i.e., those that can fulfill immediate goals-a water bottle to assuage their thirst, money they can win, a personality test providing favorable feedback) as physically closer to them than less desirable objects. Biased distance perception was revealed through verbal reports and through actions toward the object (e.g., underthrowing a beanbag at a desirable object). We suggest that seeing desirable objects as closer than less desirable objects serves the self-regulatory function of energizing the perceiver to approach objects that fulfill needs and goals.

Le Chatelier's principle in replicator dynamics

NASA Astrophysics Data System (ADS)

Allahverdyan, Armen E.; Galstyan, Aram

2011-10-01

The Le Chatelier principle states that physical equilibria are not only stable, but they also resist external perturbations via short-time negative-feedback mechanisms: a perturbation induces processes tending to diminish its results. The principle has deep roots, e.g., in thermodynamics it is closely related to the second law and the positivity of the entropy production. Here we study the applicability of the Le Chatelier principle to evolutionary game theory, i.e., to perturbations of a Nash equilibrium within the replicator dynamics. We show that the principle can be reformulated as a majorization relation. This defines a stability notion that generalizes the concept of evolutionary stability. We determine criteria for a Nash equilibrium to satisfy the Le Chatelier principle and relate them to mutualistic interactions (game-theoretical anticoordination) showing in which sense mutualistic replicators can be more stable than (say) competing ones. There are globally stable Nash equilibria, where the Le Chatelier principle is violated even locally: in contrast to the thermodynamic equilibrium a Nash equilibrium can amplify small perturbations, though both types of equilibria satisfy the detailed balance condition.

Le syndrome d'embolie graisseuse est une complication grave des fractures des os longs, il est la conséquence de la dissémination des particules graisseuses dans la microcirculation. L'objectif de ce travail est de déterminer le profil épidémiologique, la présentation clinique et paraclinique de ce syndrome et sa prise en charge thérapeutique. Notre étude porte sur 11 cas de syndrome d'embolie graisseuse colligés au service de réanimation A1 au centre hospitalier universitaire Hassan II de Fès, de Janvier 2009 à Juin 2012. Le diagnostic positif est basé sur les critères de Gurd. Les cas collectés se caractérisent par la prédominance du sexe masculin, d'un âge inférieur à 40 ans, présentant une fracture fémorale. Ce syndrome survient souvent dans les 72 heures après le traumatisme. La présentation clinique est dominée par l'hypoxémie et les troubles de conscience. Sur le plan biologique: l'anémie et la thrombopénie sont les manifestations les plus fréquentes. La prise en charge est symptomatique, 63% des patients ont nécessité l'intubation et la ventilation. L’évolution n'est pas toujours bénigne. Nos résultats confirme le polymorphisme de la présentation clinique et paraclinique du syndrome d'embolie graisseuse. Le diagnostic de ce syndrome se base sur des critères cliniques, mais reste essentiellement un diagnostic d’élimination. La prise en charge est symptomatique. La prévention de ce syndrome est essentielle et se base sur une fixation précoce des fractures des os longs. PMID:25452829

Desire thinking as a confounder in the relationship between mindfulness and craving: Evidence from a cross-cultural validation of the Desire Thinking Questionnaire.

Desire thinking and mindfulness have been associated with craving. The aim of the present study was to validate the French version of the Desire Thinking Questionnaire (DTQ) and to investigate the relationship between mindfulness, desire thinking and craving among a sample of university students. Four hundred and ninety six university students completed the DTQ and measures of mindfulness, craving and alcohol use. Results from confirmatory factor analyses showed that the two-factor structure proposed in the original DTQ exhibited suitable goodness-of-fit statistics. The DTQ also demonstrated good internal reliability, temporal stability and predictive validity. A set of linear regressions revealed that desire thinking had a confounding effect in the relationship between mindfulness and craving. The confounding role of desire thinking in the relationship between mindfulness and craving suggests that interrupting desire thinking may be a viable clinical option aimed at reducing craving.

Social desirability has been shown to be stable in samples with higher school education. However, little is known about the stability of social desirability in more heterogeneous samples differing in school education. This study aimed to investigate the stability of social desirability and which factors predict interindividual differences in intraindividual change. As part of a randomized controlled trial, 1,243 job seekers with unhealthy alcohol use were systematically recruited at three job agencies. A total of 1,094 individuals (87.8%) participated in at least one of two follow-ups (6 and 15 months after baseline) and constitute this study's sample. The Social Desirability Scale-17 was applied. Two latent change models were conducted: Model 1 tested for interindividual differences in intraindividual change of social desirability between both follow-ups; Model 2 included possible predictors (age, sex, education, current employment status) of interindividual differences in intraindividual change. Model 1 revealed a significant decrease of social desirability over time. Model 2 revealed school education to be the only significant predictor of change. These findings indicate that stability of social desirability may depend on school education. It may not be as stable in individuals with higher school education as in individuals with lower education. © 2014 Wiley Periodicals, Inc.

2010-03-01

The literature on women's sexual desire is reviewed with an emphasis on definitional challenges, an assessment of the empirical basis for the distinction between spontaneous and responsive desire, a reconsideration of the extent to which women's sexual desire is relational in nature, and an exploration of the incentive value of sex for women as a factor partially independent from the experience of sexual desire. Nine recommendations are made regarding research and diagnostic directions. The article concludes with an appeal for the inclusion of eroticism in research and clinical work on sexual desire.

Maintaining sexual desire in intimate relationships: the importance of approach goals.

Impett, Emily At; Strachman, Amy; Finkel, Eli J; Gable, Shelly L

2008-05-01

Three studies tested whether adopting strong (relative to weak) approach goals in relationships (i.e., goals focused on the pursuit of positive experiences in one's relationship such as fun, growth, and development) predict greater sexual desire. Study 1 was a 6-month longitudinal study with biweekly assessments of sexual desire. Studies 2 and 3 were 2-week daily experience studies with daily assessments of sexual desire. Results showed that approach relationship goals buffered against declines in sexual desire over time and predicted elevated sexual desire during daily sexual interactions. Approach sexual goals mediated the association between approach relationship goals and daily sexual desire. Individuals with strong approach goals experienced even greater desire on days with positive relationship events and experienced less of a decrease in desire on days with negative relationships events than individuals who were low in approach goals. In two of the three studies, the association between approach relationship goals and sexual desire was stronger for women than for men. Implications of these findings for maintaining sexual desire in long-term relationships are discussed. (c) 2008 APA, all rights reserved

The Experimental Manipulation of Desire Thinking in Alcohol use Disorder.

PubMed

Caselli, Gabriele; Gemelli, Antonella; Spada, Marcantonio M

2017-03-01

Desire thinking is a voluntary cognitive process involving verbal and imaginal elaboration of a desired target. Recent research has revealed that desire thinking may play a significant role in the escalation of craving. The goal of this study was to explore the effect of a desire thinking induction on craving in a sample of patients with alcohol use disorder. Ten patients with alcohol use disorder were exposed to a brief exposure to alcohol-related thoughts plus desire thinking induction versus brief exposure to alcohol-related thoughts plus distraction. The induction of desire thinking led to a significant increase in distress and urge to use alcohol when compared to a behavioural assessment test and a distraction task. The clinical implications for the treatment of alcohol use disorder are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Psychotherapeutic strategies that target desire thinking, both at the assessment and at the intervention levels, may be relevant in the treatment of craving-related problems. Deriving and illustrating the role of desire thinking in a given episode of craving may support the development of metacognitive awareness about its functions and consequences.

Objectif Examiner la façon dont le stress familial influence le contrôle glycémique chez les patients diabétiques de moins de 18 ans. Sources des données Une recherche des études pertinentes publiées depuis 1990 a été réalisée dans PubMed et Scopus à l'aide des mots-clés suivants en anglais: diabetes type 1, glycemic control, family stress, family conflict et family function. Sélection des études La recension initiale a permis de cerner un total de 1 478 articles. La synthèse finale portrait sur 6 études de cohortes, 3 études transversales et 1 étude qualitative dans lesquelles le stress familial était évalué à l'aide d'instruments de mesure des conflits spécifiquement reliés au diabète et le contrôle glycémique était mesuré en fonction de l'hémoglobine glycosylée. Synthèse Dans la plupart des études, il existait une corrélation négative entre le stress familial et le contrôle glycémique des patients. Le bon fonctionnement familial était fortement relié à un bon contrôle glycémique des patients, tandis que les conflits familiaux étaient associés à un mauvais contrôle glycémique. Les familles dont la situation socioéconomique était défavorisée, celles ayant des adolescents atteints de diabète et les familles monoparentales étaient plus enclines à vivre un stress relié au diabète et étaient, par conséquent, plus susceptibles de connaître un moins bon contrôle glycémique. Conclusion Les interventions psychologiques thérapeutiques et les programmes éducatifs peuvent aider à atténuer le stress familial relié au diabète et amélioreront probablement le contrôle glycémique.

Sex steroids and genital surgery are known to affect sexual desire, but little research has focused on the effects of cross-sex hormone therapy and sex reassignment surgery on sexual desire in trans persons. This study aims to explore associations between sex reassignment therapy (SRT) and sexual desire in a large cohort of trans persons. A cross-sectional single specialized center study including 214 trans women (male-to-female trans persons) and 138 trans men (female-to-male trans persons). Questionnaires assessing demographics, medical history, frequency of sexual desire, hypoactive sexual desire disorder (HSDD), and treatment satisfaction. In retrospect, 62.4% of trans women reported a decrease in sexual desire after SRT. Seventy-three percent of trans women never or rarely experienced spontaneous and responsive sexual desire. A third reported associated personal or relational distress resulting in a prevalence of HSDD of 22%. Respondents who had undergone vaginoplasty experienced more spontaneous sexual desire compared with those who planned this surgery but had not yet undergone it (P = 0.03). In retrospect, the majority of trans men (71.0%) reported an increase in sexual desire after SRT. Thirty percent of trans men never or rarely felt sexual desire; 39.7% from time to time, and 30.6% often or always. Five percent of trans men met the criteria for HSDD. Trans men who were less satisfied with the phalloplasty had a higher prevalence of HSDD (P = 0.02). Trans persons who were more satisfied with the hormonal therapy had a lower prevalence of HSDD (P = 0.02). HSDD was more prevalent in trans women compared with trans men. The majority of trans women reported a decrease in sexual desire after SRT, whereas the opposite was observed in trans men. Our results show a significant sexual impact of surgical interventions and both hormonal and surgical treatment satisfaction on the sexual desire in trans persons. © 2013 International Society for Sexual

Résumé Cette étude vise à documenter le rôle médiateur des symptômes de stress post-traumatique (SSPT) dans le lien entre l’agression sexuelle et différentes formes de victimisation vécues dans le contexte de relations amoureuses. L’étude se fonde sur l’Enquête sur les parcours amoureux des jeunes (PAJ), réalisée au sein de 34 écoles secondaires du Québec. Les jeunes ont rempli un questionnaire portant sur leurs expériences de victimisation, y compris l’agression sexuelle vécue pendant l’enfance et la violence psychologique, physique et sexuelle vécue au sein de leurs relations amoureuses dans les 12 derniers mois. Les SSPT ont été évalués à l’aide du UCLA PTSD Index. Sur un total de 8 194 adolescents, 15% des filles et 4% des garçons ont rapporté avoir vécu une agression sexuelle. Les résultats des analyses acheminatoires semblent indiquer que le fait d’avoir été victime d’agression sexuelle est associé à davantage de SSPT et qu’en retour, les SSPT sont positivement associés à la violence psychologique, physique et sexuelle subie de la part d’un partenaire amoureux. Cette étude comporte des implications pratiques pour la prévention et l’intervention sur le plan de la violence dans les relations amoureuses chez les victimes d’agression sexuelle. PMID:29321695

Composition du comité Des spécialistes et des délégués de diverses régions du Canada et représentant diverses disciplines pertinentes ont discuté et se sont mis d’accord sur les révisions à apporter aux lignes directrices de 2006. Méthodologie On a eu recours au système GRADE (grading of recommendations, assessment, development, and evaluation) pour évaluer le consensus concernant les recommandations, lequel était défini comme suit : lorsque 80 % ou plus des participants ont voté en faveur de la recommandation. La cote des données probantes est rapportée lorsque cela est possible. Rapport important pour les médecins de famille, malgré les progrès effectués dans les domaines des biomarqueurs liquidiens et de la neuro-imagerie, le diagnostic de démence au Canada demeure fondamentalement clinique. De nouveaux critères cliniques essentiels de diagnostic de la maladie d’Alzheimer en reconnaissent dorénavant les formes moins fréquentes et non amnestiques. La démence précoce, une affection rare, mais importante, devrait inciter les médecins à aiguiller les patients vers un spécialiste ayant accès à des conseillers en génétique. La démence d’évolution rapide, mal définie dans la littérature, faciliterait le dépistage de cette affection rare, mais importante. Les inhibiteurs de la cholinestérase sont maintenant indiqués pour le traitement d’affections autres que la maladie d’Alzheimer.

Introduction Le diabète est définit comme un trouble de l'assimilation, de l'utilisation et du stockage des sucres apportés par l'alimentation, sa prise en charge est assurée par le suivi du surpoids et l'obésité et le contrôle glycémique régulier. L'objectif de ce travail était l'étude du surpoids, l'obésité et le contrôle glycémique chez 2227 diabétiques de différent type (type 1, 2 et gestationnel), consultants le centre de référence provincial de diabète (CRD), Kénitra-Maroc. Méthodes L'étude s'est déroulée sur une période d'une année du mois janvier au mois décembre 2015, L'évaluation du surpoids et l'obésité a été effectuée par le calcul de l'Indice de Masse Corporelle (IMC=Poids/Taille2 (Kg/m2)), elles sont définit respectivement par IMC > 25 Kg/m2, et IMC > 30 Kg/m2, le poids et la taille ont été mesurés selon les recommandations de l'organisation mondiale de santé (OMS), Le contrôle glycémique a été effectué par l'analyse sanguine de l'Hémoglobine glycosylée et de la Glycémie à jeun. Les normes sont 7% pour l'Hémoglobine glycosylée et 0,70g/l à 1,10g/l pour la Glycémie à jeun. Résultats L'intervalle d'âges des patients est compris entre 8 mois et 80 ans, avec une dominance des diabétiques provenant du milieu urbain (74%) par rapport à ceux provenant du milieu rural (26%). Le surpoids touche l'ensemble de cette population. L'IMC moyen des femmes tends vers l'obésité (IMC≈30): (29,21 Kg/m2 ± 3,1) pour le diabète gestationnel et (29,15 Kg/m2 ± 3,2) pour le diabète de type 2. Les valeurs du contrôle glycémique sont supérieures aux normes: avec 8,5% ± 2,6 > 7% pour l'hémoglobine glycosylée et 1,5 g/l ± 1,3 > 1,10g/l pour la Glycémie à jeun. La différence entre les valeurs de l'hémoglobine glycosylée entre les hommes (8,5 7% ± 2,6) et les femmes (8,1% ± 2,3) n'est pas significative (P > 0,05), même chose pour la Glycémie capillaire à jeun: pour les hommes (1,44 g/l ± 1,1) et les

Values reflect how people want to experience the world; emotions reflect how people actually experience the world. Therefore, we propose that across cultures people desire emotions that are consistent with their values. Whereas prior research focused on the desirability of specific affective states or 1 or 2 target emotions, we offer a broader account of desired emotions. After reporting initial evidence for the potential causal effects of values on desired emotions in a preliminary study (N = 200), we tested the predictions of our proposed model in 8 samples (N = 2,328) from distinct world cultural regions. Across cultural samples, we found that people who endorsed values of self-transcendence (e.g., benevolence) wanted to feel more empathy and compassion, people who endorsed values of self-enhancement (e.g., power) wanted to feel more anger and pride, people who endorsed values of openness to change (e.g., self-direction) wanted to feel more interest and excitement, and people who endorsed values of conservation (e.g., tradition) wanted to feel more calmness and less fear. These patterns were independent of differences in emotional experience. We discuss the implications of our value-based account of desired emotions for understanding emotion regulation, culture, and other individual differences.

Evidence-based treatments for low sexual desire in women.

PubMed

Brotto, Lori A

2017-04-01

Low sexual desire is the most common sexual complaint in women, with multinational studies finding that at least a third of women experience low sexual desire. No single etiology for the development of Female Sexual Interest/Arousal Disorder, the diagnosis laid out by the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders, has been established. There has been considerable interest in pharmacological approaches to improving low desire, and agents targeting a range of neurotransmitters have been examined. To date, only flibanserin, a centrally acting medication targeting the serotonin, dopamine, and norepinephrine systems, has been approved by the Food and Drug Administration (FDA). Despite statistically significant effects on sexual desire, sexual distress, and sexually satisfying events, side-effects are significant, and flibanserin is completely contraindicated with alcohol. As such, there has been renewed interest in advancing the science of psychological approaches to low desire, including cognitive behavioral and mindfulness therapies. Copyright © 2017 Elsevier Inc.

The DSM diagnostic criteria for hypoactive sexual desire disorder in women.

PubMed

Brotto, Lori A

2010-04-01

Hypoactive Sexual Desire Disorder (HSDD) is one of two sexual desire disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and is defined by the monosymptomatic criterion "persistently or recurrently deficient (or absent) sexual fantasies and desire for sexual activity" that causes "marked distress or interpersonal difficulty." This article reviews the diagnosis of HSDD in prior and current (DSM-IV-TR) editions of the DSM, critiques the existing criteria, and proposes criteria for consideration in DSM-V. Problems in coming to a clear operational definition of desire, the fact that sexual activity often occurs in the absence of desire for women, conceptual issues in understanding untriggered versus responsive desire, the relative infrequency of unprovoked sexual fantasies in women, and the significant overlap between desire and arousal are reviewed and highlight the need for revised DSM criteria for HSDD that accurately reflect women's experiences. The article concludes with the recommendation that desire and arousal be combined into one disorder with polythetic criteria.

Romantic love and sexual desire in close relationships.

PubMed

Gonzaga, Gian C; Turner, Rebecca A; Keltner, Dacher; Campos, Belinda; Altemus, Margaret

2006-05-01

Drawing on recent claims in the study of relationships, attachment, and emotion, the authors hypothesized that romantic love serves a commitment-related function and sexual desire a reproduction-related function. Consistent with these claims, in Study 1, brief experiences of romantic love and sexual desire observed in a 3-min interaction between romantic partners were related to distinct feeling states, distinct nonverbal displays, and commitment- and reproductive-related relationship outcomes, respectively. In Study 2, the nonverbal display of romantic love was related to the release of oxytocin. Discussion focuses on the place of romantic love and sexual desire in the literature on emotion. 2006 APA, all rights reserved

Each of 100 4th-graders completed 2 telephone interviews 28 days apart. CSD scores had adequate internal consistency and test-retest reliability, and a 14-item subset was identified that sufficiently measures the same construct. Our C-SDF scale performed less well in terms of internal consistency and test-retest reliability; factor analysis revealed 2 factors, 1 of which was moderately related to the CSD. The 14-item subset of the CSD scale may help researchers understand error in children's dietary reports.

Three approaches to define desired soil organic matter contents.

PubMed

Sparling, G; Parfitt, R L; Hewitt, A E; Schipper, L A

2003-01-01

Soil organic C is often suggested as an indicator of soil quality, but desirable targets are rarely specified. We tested three approaches to define maximum and lowest desirable soil C contents for four New Zealand soil orders. Approach 1 used the New Zealand National Soils Database (NSD). The maximum C content was defined as the median value of long-term pastures, and the lower quartile defined the lowest desirable soil C content. Approach 2 used the CENTURY model to predict maximum C contents of long-term pasture. Lowest desirable content was defined by the level that still allowed recovery to 80% of the maximum C content over 25 yr. Approach 3 used an expert panel to define desirable C contents based on production and environmental criteria. Median C contents (0-20 cm) for the Recent, Granular, Melanic, and Allophanic orders were 72, 88, 98, 132 Mg ha(-1), and similar to contents predicted by the CENTURY model (78, 93, 102, and 134 Mg ha(-1), respectively). Lower quartile values (54, 78, 73, and 103 Mg ha(-1), respectively) were similar to the lowest desirable C contents calculated by CENTURY (55, 54, 67, and 104 Mg ha(-1), respectively). Expert opinion was that C contents could be depleted below these values with tolerable effects on production but less so for the environment. The CENTURY model is our preferred approach for setting soil organic C targets, but the model needs calibrating for other soils and land uses. The statistical and expert opinion approaches are less defensible in setting lower limits for desirable C contents.

Use of Social Desirability Scales in Clinical Psychology: A Systematic Review.

PubMed

Perinelli, Enrico; Gremigni, Paola

2016-06-01

There is still an open debate about the utility of social desirability indicators. This report systematically reviewed the use of social desirability scales in studies addressing social desirability in clinical psychology. A systematic review (January 2010-March 2015) was conducted, including 35 studies meeting the inclusion criteria of being published in peer-reviewed journals and describing quantitative findings about an association of social desirability with clinical psychology variables using a cross-sectional or longitudinal design. Social desirability was associated with self-reports of various clinical-psychological dimensions. Most of the included studies treated social desirability as a 1-dimensional variable and only 10 of 35 disentangled the impression management and self-deception components. Although theoretical literature does not consider social desirability a mere response bias, only 4 of the reviewed articles controlled for the possible suppressor effect of personality variables on social desirability, while the majority focused upon the stylistic (response bias) rather than the substantive (personality) nature of this construct. The present review highlighted some limitations in the use of social desirability scales in recent clinical psychology research and tried to offer a few suggestions for handling this issue. © 2016 Wiley Periodicals, Inc.

Sex, desire and pleasure: considering the experiences of older Australian women

PubMed Central

Fileborn, Bianca; Thorpe, Rachel; Hawkes, Gail; Minichiello, Victor; Pitts, Marian; Dune, Tinashe

Older age is often associated with asexuality. That is, older individuals are not viewed as desiring of sex, nor as sexually desirable to others. Broader social and cultural norms that downplay women's sexual desire and agency further compound these phenomena. Whether this popular image accurately reflects older women's sexual desires, behaviour and capacity to experience pleasure is unclear. Drawing on semi-structured interviews with 43 partnered Australian women aged 55–81, this article considers women's sexual experiences and desires in older age. The findings of our research confirm that older women's experiences of sex and sexual desire are diverse and fluid. Some of the factors that influenced participants’ sexual behaviour and desire will be considered in this article, as will their understandings of what “counts” as sexual satisfaction and “successful sex”. The factors affecting sexual behaviour and desire also influence the way in which women are able to negotiate sexual interaction with their partners. Participants expressed a need for education and resources in order to gain greater control and to make autonomous choices over their sexual experiences, desire and ability to give and receive pleasure. The implications of these findings for practitioners are also considered. PMID:25544829

[Desire for a child and desired children--possibilities and limits of reproductive biomedicine].

2006-03-01

Definition of problem: Reproductive Biomedicine and new reproductive technologies (ART) belong to the fields of medicine that initiated most of the discussion on enhancement and desire fulfilling medicine in bioethics during the last years. One of the crucial questions to be answered is the definition of the right to procreate/right for a genetically related child. Closely connected are controversial opinions in regard to the definition of sterility as a disease/illness, or a mere fate, or malfunction, which does not have to be medically cured. Arguments: After a cursory description of the national and international debate, we introduce some results of our 'bioethical field studies', exploring and comparing the views of experts (human geneticists, ethicists, pediatricians, obstetricians and midwifes) and couples/patients (IVF couples, high genetic risk couples and couples with no known risk for an inherited disease or infertility problem) on sterility, the right to procreate, possibilities and appropriate limits of IVF in Germany. According to the WHO, sterility has to be defined as an illness, if the respective couples have a desire for a child. IVF can be a means for a cure. Since 2004, Germany does no longer supply a thoroughly insurer financed IVF treatment. Our surveys indicate that this change, though supported by many experts, is hard to accept for couples concerned. Only obstetricians share the WHO's view that sterility should count as an illness. Many ethicists see a proclaimed human right to procreate as merely negative right, although many support free IVF treatment for poor couples. We challenge the expert majority view on the basis of the capability approach (Amartya Sen) and functional liberalism (Herlinde Pauer Studer) and with a view to the international state of the art in IVF. The desire to have children cannot be reduced to a non-authoritative preference whose fulfillment is optional, but has to be conceptualized as a normative need that ought to

Everyday temptations: an experience sampling study of desire, conflict, and self-control.

How often and how strongly do people experience desires, to what extent do their desires conflict with other goals, and how often and successfully do people exercise self-control to resist their desires? To investigate desire and attempts to control desire in everyday life, we conducted a large-scale experience sampling study based on a conceptual framework integrating desire strength, conflict, resistance (use of self-control), and behavior enactment. A sample of 205 adults wore beepers for a week. They furnished 7,827 reports of desire episodes and completed personality measures of behavioral inhibition system/behavior activation system (BIS/BAS) sensitivity, trait self-control, perfectionism, and narcissistic entitlement. Results suggest that desires are frequent, variable in intensity, and largely unproblematic. Those urges that do conflict with other goals tend to elicit resistance, with uneven success. Desire strength, conflict, resistance, and self-regulatory success were moderated in multiple ways by personality variables as well as by situational and interpersonal factors such as alcohol consumption, the mere presence of others, and the presence of others who already had enacted the desire in question. Whereas personality generally had a stronger impact on the dimensions of desire that emerged early in its course (desire strength and conflict), situational factors showed relatively more influence on components later in the process (resistance and behavior enactment). In total, these findings offer a novel and detailed perspective on the nature of everyday desires and associated self-regulatory successes and failures. 2012 APA, all rights reserved

Three-dimensional desirability spaces for quality-by-design-based HPLC development.

Mokhtar, Hatem I; Abdel-Salam, Randa A; Hadad, Ghada M

2015-04-01

In this study, three-dimensional desirability spaces were introduced as a graphical representation method of design space. This was illustrated in the context of application of quality-by-design concepts on development of a stability indicating gradient reversed-phase high-performance liquid chromatography method for the determination of vinpocetine and α-tocopheryl acetate in a capsule dosage form. A mechanistic retention model to optimize gradient time, initial organic solvent concentration and ternary solvent ratio was constructed for each compound from six experimental runs. Then, desirability function of each optimized criterion and subsequently the global desirability function were calculated throughout the knowledge space. The three-dimensional desirability spaces were plotted as zones exceeding a threshold value of desirability index in space defined by the three optimized method parameters. Probabilistic mapping of desirability index aided selection of design space within the potential desirability subspaces. Three-dimensional desirability spaces offered better visualization and potential design spaces for the method as a function of three method parameters with ability to assign priorities to this critical quality as compared with the corresponding resolution spaces. © The Author 2014.

Violation of eating expectancies does not reduce conditioned desires for chocolate.

2016-05-01

Although eating desires can be easily learned, their extinction appears more difficult. The present two-session study aimed to investigate the role of eating expectancies in the short and longer-term extinction of eating desires. In addition, the relationship between eating desires and conditioned evaluations was examined to test whether they might share a similar mechanism. It was hypothesized that the short-term extinction of eating desires would be more successful after the disconfirmation of eating expectancies (instructed extinction or IE), while resulting in worse longer-term extinction because omission of the food reward during extinction is not surprising. In contrast to the hypotheses, it was found that IE had no effect on the short-term and longer-term extinction of eating desires. Eating desires correlated with conditioned evaluations only to some extent. It is concluded that eating expectancies do not mediate the short-term extinction of conditioned eating desires. In addition, their longer-term extinction does not appear to be facilitated by a greater violation of eating expectancies. This suggests that it might not be necessary to focus on expectancy violation in cue exposure therapy to reduce eating desires. Copyright © 2016 Elsevier Ltd. All rights reserved.

To examine factors associated with desire for autonomy in health care decisions in the general population. Mailed survey of 2348 residents of Geneva, Switzerland. Participants answered questions on a scale measuring their desire for autonomy in health care decisions. The scale was scored between 0 (lowest desire for autonomy) and 100 (highest desire for autonomy). On average the respondents favoured shared or active involvement in medical decisions (mean score 62.0, SD 20.9), but attitudes varied considerably. In the multivariate model, factors associated with a higher desire for autonomy included female gender, younger age, higher education, living alone, reporting an excellent global health and - a new observation compared to previous studies - having made several medical decisions in the past 6 months. The attitudes of the general public appear to be consistent with the model of shared decision making. However, people vary considerably in their desire for autonomy. An explicit assessment of each individual's desire for autonomy may improve the decision-making process. Such an assessment should be repeated regularly, as familiarity with medical decisions may increase the desire for autonomy. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

La trithérapie antirétrovirale a contribué à une baisse considérable de la mortalité liée au VIH. Les causes de décès sont dominées par les infections opportunistes dans les pays en voie de développement et par les maladies cardiovasculaires et les cancers dans les pays développés. L’objectif était de déterminer les causes et les facteurs de risque de décès des patients infectés par le VIH dans le Centre Tunisien. Une étude transversale auprès des patients infectés par le VIH âgés de plus de 15 ans suivis à Sousse et à Monastir entre 2000 et 2014. Le décès était considéré lié au VIH si la cause était un évènement classant SIDA ou s’il était la conséquence d’une infection opportuniste d’étiologie indéterminée avec des CD4 < 50/mm3, non lié au VIH si la cause n’était pas un évènement classant SIDA, et de cause inconnue si aucune information n’était disponible. Deux cents treize patients, 130 hommes (61%) et 83 femmes (39%), d’âge moyen 40±11 ans ont été inclus. Cinquante quatre patients sont décédés, avec une mortalité de 5,4/100 patients-années. La mortalité annuelle a baissé de 5,8% en 2000-2003 à 2,3% en 2012-2014. La survie était de 72% à 5 ans et de 67% à 10 ans. Les décès étaient liés au VIH dans 70,4% des cas. Les causes de décès les plus fréquentes étaient la pneumocystose pulmonaire et la cryptococcose neuroméningée dans 6 cas (11%) chacune. Les facteurs de risque de décès étaient les antécédents d’infections opportunistes, la durée de la trithérapie antirétrovirale < 12 mois et le tabagisme. Le renforcement du dépistage, l’initiation précoce de la trithérapie antirétrovirale, et la lutte contre le tabagisme sont nécessaires afin de réduire la mortalité chez les patients infectés par le VIH en Tunisie.

Le Châtelier reciprocal relations and the mechanical analog

NASA Astrophysics Data System (ADS)

Gilmore, Robert

1983-08-01

Le Châtelier's principle is discussed carefully in terms of two sets of simple thermodynamic examples. The principle is then formulated quantitatively for general thermodynamic systems. The formulation is in terms of a perturbation-response matrix, the Le Châtelier matrix [L]. Le Châtelier's principle is contained in the diagonal elements of this matrix, all of which exceed one. These matrix elements describe the response of a system to a perturbation of either its extensive or intensive variables. These response ratios are inverses of each other. The Le Châtelier matrix is symmetric, so that a new set of thermodynamic reciprocal relations is derived. This quantitative formulation is illustrated by a single simple example which includes the original examples and shows the reciprocities among them. The assumptions underlying this new quantitative formulation of Le Châtelier's principle are general and applicable to a wide variety of nonthermodynamic systems. Le Châtelier's principle is formulated quantitatively for mechanical systems in static equilibrium, and mechanical examples of this formulation are given.

From simple desires to ordinary beliefs: the early development of everyday psychology.

PubMed

Wellman, H M; Woolley, J D

1990-06-01

We provide evidence for the claim that before young children construe human action in terms of beliefs and desires they understand action only in terms of simple desires. This type of naive psychology--a simple desire psychology--constitutes a coherent understanding of human action, but it differs from the belief--desire psychology of slightly older children and adults. In this paper we characterize what we mean by a simple desire psychology and report two experiments. In Experiment 1 we demonstrate that 2-year-old can predict actions and reactions related to simple desires. In Experiment 2 we demonstrate that many 2-year-old pass desire reasoning tasks while at the same time failing belief reasoning tasks that are passed by slightly older children, and that are as comparable as possible to the desire tasks they pass with ease.

Desire for Sweet Taste Unchanged After Eating: Evidence of a Dessert Mentality?

Added sugars provide calories and desirability to foods and beverages. Our aim was to test whether desire for a sweet taste would be better maintained than a desire for other tastes for 3 hours after a test meal. Eighty-three young adults ate 2 slices of bread on 2 separate occasions after which they were asked to rate their desire for savory, sweet, fatty, or salty tastes and to specify the number of servings of white rice, pizza, cheese and crackers, sweet biscuits, and pasta they could consume. Desirability was assessed using 100-mm visual analog scales (VAS), with 0 mm representing no desire and 100 mm great desire. When participants provided a quantitative assessment of the servings of foods that they wanted to eat following the bread meal, desire decreased on average for all foods measured, χ 2 (3) = 2.63, p = 0.452. Mean (95% confidence interval [CI]) change in VAS taste desirability 30 minutes after eating declined for salty (14.5 mm [10.5, 18.6]), fatty (11.2 mm [7.1, 15.2]), and savory (24.1 mm [19.7, 28.5]) tastes (p < 0.001). Desirability for sweet taste did not differ from baseline (2.4 mm [-2.3, 7.1]), and this level of desire was maintained throughout the 3-hour period. The data indicate a partial disconnection between appetite and desirability for sweet taste. Physiological and psychosocial reward systems may make it difficult for people to resist sweet tasting foods and beverages. Targeting familial and cultural practices that discourage the consumption of added sugar foods might be useful to combat desire-driven food intake.

Desire understanding in 2-year-old children: An eye-tracking study.

Vaish, Amrisha; Hepach, Robert; Grossmann, Tobias

2018-05-21

'Much research has investigated children's understanding of others' mental states in terms of beliefs, but far less is known about their understanding of others' desires. To fill this gap, we used an eye-tracking paradigm to test 2-year-old children's desire understanding by measuring their anticipatory looking behavior as well as changes in their internal arousal (i.e., changes in pupil dilation). Children showed increased pupil dilation when an adult reached for an object she had previously emoted negatively towards (the object incongruent with her desire). Children also showed weaker evidence of anticipating that an adult will reach for an object that she had emoted positively towards (the object congruent with her desire). These results suggest that 2-year-olds robustly recognize whether or not an individual's actions are consistent with her desires, and seem to have a budding capacity to predict an individual's actions based on her desires. Thus, by age 2 years, children are on their way to acquiring a robust desire psychology. Copyright © 2018 Elsevier Inc. All rights reserved.

Belief-desire reasoning as a process of selection.

PubMed

Leslie, Alan M; German, Tim P; Polizzi, Pamela

2005-02-01

Human learning may depend upon domain specialized mechanisms. A plausible example is rapid, early learning about the thoughts and feelings of other people. A major achievement in this domain, at about age four in the typically developing child, is the ability to solve problems in which the child attributes false beliefs to other people and predicts their actions. The main focus of theorizing has been why 3-year-olds fail, and only recently have there been any models of how success is achieved in false-belief tasks. Leslie and Polizzi (Inhibitory processing in the false-belief task: Two conjectures. Developmental Science, 1, 247-254, 1998) proposed two competing models of success, which are the focus of the current paper. The models assume that belief-desire reasoning is a process which selects a content for an agent's belief and an action for the agent's desire. In false belief tasks, the theory of mind mechanism (ToMM) provides plausible candidate belief contents, among which will be a 'true-belief.' A second process reviews these candidates and by default will select the true-belief content for attribution. To succeed in a false-belief task, the default content must be inhibited so that attention shifts to another candidate belief. In traditional false-belief tasks, the protagonist's desire is to approach an object. Here we make use of tasks in which the protagonist has a desire to avoid an object, about which she has a false-belief. Children find such tasks much more difficult than traditional tasks. Our models explain the additional difficulty by assuming that predicting action from an avoidance desire also requires an inhibition. The two processing models differ in the way that belief and desire inhibitory processes combine to achieve successful action prediction. In six experiments we obtain evidence favoring one model, in which parallel inhibitory processes cancel out, over the other model, in which serial inhibitions force attention to a previously

There is controversy about the nature of women's sexual desire. The aim was to explore narrative descriptions of sexual desire among mid-aged women in hopes of clarifying how women define and experience sexual desire, and how these might differ among women with and without female sexual arousal disorder (FSAD). Mid-aged women without (age: M = 45, n = 12) and with (age: M = 55, n = 10) FSAD took part in in-depth interviews that invited them to share personal stories of sexual desire. Women also completed the Brief Index of Sexual Functioning and the Female Sexual Function Index (FSFI). Women in both groups described sexual desire in genital, non-genital physical, and in cognitive-emotional terms. Although women with FSAD had low ratings of sexual desire on the FSFI, they could recall recent experiences of desire that did not differ from the control group. Women identified a number of triggers of desire including touch, memories, and partner's responses--the latter of which acted as both a trigger and an inhibitor. Women in the control group were more likely to express conflation about the distinction between desire and arousal. Among the different "objects" of women's desire, most women acknowledged emotional connection as most important.

As a mental response to sexual stimuli, sexual desire determines human sexual behavior and represents the cognitive capacity of sexual stimulation, so that avoiding sexual activity has a very negative effect on the discharge of intimacy and joy in couple's relationship and threatens the stability relationship, which can finally end in sexual dissatisfaction and divorce; it may even affect the reproduction. This study, reviews the literature on biopsychosocial determinants of hypoactive sexual desire disorder in women in childbearing ages. The search was done from January to March 2015 by the use of the data bases ProQuest, Pubmed, CINAHL, Ovid and Medline and the words sexual desire, related factors and biopsychosocial determinants were used as free text words. The words reduce sexual desire, hypoactive sexual desire disorder, dyadic relationship, biopsychosocial factors and women were used as keywords in the search. Also, the articles focusing on any aspects of sexual desire such as biological, social and psychological factors and relationship factors alone or integrated, were included in the study. The articles which specifically targeted the hypoactive sexual desire disorder in pregnant and lactating women and also the articles targeting biopsychosocial factors related to other types of sexual function disorder such as arousal disorder, orgasm disorder and dyspareunia, were all excluded from this study. After reviewing the literature, the findings were categorized in three main class of effect of biologic factors on sexual desire and sexual hypoactivity, the effect of psychological factors on sexual desire and the effect of cultural factors and couple's relationship on sexual desire, each of these domains cover a wide range (such as hormonal changes, chronic diseases, psychological difficulties (perceived stress, anxiety, depression). Incompatibility of couples, the spouse's sexual function disorder) which may overlap. Because of the complexity of etiology and

Les douleurs lombaires relèvent d'étiologies multiples dont le diagnostic peut être source de grandes difficultés. Le lymphome rachidien primitif est rare et son diagnostic nécessite une biopsie souvent scanoguidée. Un homme de 30 ans, était hospitalisé pour lombalgies inflammatoires évoluant dans un contexte d'altération de l'état général avec à l'examen des douleurs à la palpation des apophyses épineux L2L3, sans syndrome tumoral périphérique. Le bilan biologique montrait un syndrome inflammatoire. Le bilan morphologique était en faveur d'une spondylodiscite. La première biopsie montrait une ostéite granulomateuse. L'aggravation clinique et radiologique sous anti bacillaire a mené à reconsidérer le diagnostic et la deuxième biopsie confirme le diagnostic du lymphome. Le diagnostic de tuberculose osseuse en particulier vertébrale nécessite une confirmation bactériologique et ou histologique pour ne pas méconnaître un lymphome osseux primitif. PMID:28292061

Social desirability in personality inventories: Symptoms, diagnosis and prescribed cure

PubMed Central

Bäckström, Martin; Björklund, Fredrik

2013-01-01

An analysis of social desirability in personality assessment is presented. Starting with the symptoms, Study 1 showed that mean ratings of graded personality items are moderately to strongly linearly related to social desirability (Self Deception, Impression formation, and the first Principal Component), suggesting that item popularity may be a useful heuristic tool for identifying items which elicit socially desirable responding. We diagnose the cause of socially desirable responding as an interaction between the evaluative content of the item and enhancement motivation in the rater. Study 2 introduced a possible cure; evaluative neutralization of items. To test the feasibility of the method lay psychometricians (undergraduates) reformulated existing personality test items according to written instructions. The new items were indeed lower in social desirability while essentially retaining the five factor structure and reliability of the inventory. We conclude that although neutralization is no miracle cure, it is simple and has beneficial effects. PMID:23252410

Hypersexuality and high sexual desire: exploring the structure of problematic sexuality.

The concept of hypersexuality has been accompanied by fierce debates and conflicting conclusions about its nature. One of the central questions under the discussion is a potential overlap between hypersexuality and high sexual desire. With the relevant research in its early phase, the structure of hypersexuality remains largely unknown. The aim of the present study was to systematically explore the overlap between problematic sexuality and high sexual desire. A community online survey was carried out in Croatia in 2014. The data were first cluster analyzed (by gender) based on sexual desire, sexual activity, perceived lack of control over one's sexuality, and negative behavioral consequences. Participants in the meaningful clusters were then compared for psychosocial characteristics. To complement cluster analysis (CA), multigroup confirmatory factor analysis (CFA) of the same four constructs was carried out. Indicators representing the proposed structure of hypersexuality were included: sexual desire, frequency of sexual activity, lack of control over one's sexuality, and negative behavioral outcomes. Psychosocial characteristics such as religiosity, attitudes toward pornography, and general psychopathology were also evaluated. CA pointed to the existence of two meaningful clusters, one representing problematic sexuality, that is, lack of control over one's sexuality and negative outcomes (control/consequences cluster), and the other reflecting high sexual desire and frequent sexual activity (desire/activity cluster). Compared with the desire/activity cluster, individuals from the control/consequences cluster reported more psychopathology and were characterized by more traditional attitudes. Complementing the CA findings, CFA pointed to two distinct latent dimensions-problematic sexuality and high sexual desire/activity. Our study supports the distinctiveness of hypersexuality and high sexual desire/activity, suggesting that problematic sexuality might be more

Osteotomies of the Le Fort I segment are routine operations with low complication rates. Ischemic complications are rare, but can have severe consequences that may lead to avascular bone necrosis of the Le Fort I segment. Therefore the aim of this study was to investigate the blood supply and special arterial variants of the Le Fort I segment responsible for arterial hypoperfusion or ischemic avascular necrosis after surgery. The arterial anatomy of the Le Fort I segment's blood supply using 30 halved human cadaver head specimens was analyzed after complete dissection until the submicroscopic level. In all specimens the arterial variants of the Le Fort I segment and also the arterial diameters measured at two points were evaluated. The typical known vascularization pattern was apparent in 90% of all specimens, in which the ascending palatine (D1: 1,2 mm ± 0,34 mm; D2: 0,8 mm ± 0,34 mm) and ascending pharyngeal artery (D1: 1,3 mm ± 0,58 mm; D2: <0,4 mm) were both supplying the Le Fort I segment. However in 10% of all specimens, the Le Fort I segment was dependent on the ascending pharyngeal artery alone and the missing ascending palatine artery was replaced with the anterior branch of the ascending pharyngeal artery (D1: 1,9 mm ± 0,32; D2: 1,0 mm ± 0,3 mm). This study is the first description of a special type of arterial variation of the Le Fort I segment. The type of this arterial variation, its clinical relevance and potential consequences are explained. Individuals with this special arterial anatomy may clinically be at a high risk for hypoperfusion and avascular segment necrosis after surgery. An individualized operation plan may prevent ischemic complications in at-risk patients. Copyright © 2018 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.

Objective. To identify participants' satisfaction with appearance and the desired treatment to improve aesthetics. Materials and Methods. 220 participants (127 males and 93 females, mean age = 21.4 ± 1.5 years) were recruited into the study. A structured questionnaire was used to assess patients' satisfaction with appearance and what treatment they desire to improve aesthetics. Participants scored the level of satisfaction with appearance using visual analogue scale. Results. The VAS mean score of satisfaction with general appearance was 6.8 ± 2.3. Half participants were dissatisfied with tooth appearance and 65.9% were dissatisfied with tooth colour. Higher VAS scores were associated with higher desire for all treatments that improve tooth appearance (P < .05). Dissatisfaction with tooth appearance increased with increased dissatisfaction with teeth colour, feeling of poor tooth alignment, presence of fractured anterior teeth, and increased desire for orthodontic, crowns, and dentures treatments (P < .05). Dissatisfaction with tooth colour was associated with increased desire for tooth whitening and tooth coloured fillings (P < .05). Conclusions. Participants had high levels of dissatisfaction with tooth appearance and tooth colour. Dissatisfaction with tooth colour contributed to the increased dissatisfaction with tooth appearance. Dissatisfaction with tooth appearance, colour, alignment, and condition was significantly related to high desire for aesthetic treatments.

Ce travail etudie les fluctuations supraconductrices dans le compose supraconducteur a haute temperature critique dope aux electrons Pr2-xCe xCuO4+delta. La technique utilisee pour sonder ces fluctuations est le transport electrique DC dans le plan ab. Il s'agit, a notre connaissance, de la premiere etude de ce type dans la classe generale des supraconducteurs a haute temperature critique dopes aux electrons et, plus particulierement, dans Pr2-xCe xCuO4+delta. De plus, l'etude est effectuee pour trois regimes de dopage, soit sous-dope x = 0.135, dopage optimal x = 0.15 et surdope x = 0.17. Les echantillons etudies sont des couches minces d'epaisseur plus grande que 100 nm crues par ablation laser. Les mesures electriques DC effectuees dans ce travail sont la resistance en reponse lineaire et les courbes IV en reponse non lineaire en fonction de la temperature. La mise en oeuvre experimentale de ces mesures a necessite une grande attention au filtrage et aux effets de chauffage a haut courant. Nous montrons que, sans cette attention, les donnees experimentales sont toujours erronees dans le regime pertinent pour nos echantillons. Les resultats pour le dopage optimal x = 0.15 sont expliques de facon tres convaincante dans le cadre de fluctuations purement 2D. D'abord, le regime des fluctuations gaussiennes est tres bien decrit par le modele d'Aslamazov-Larkin en deux dimensions. Ensuite, le regime de fluctuations critiques, se trouvant a plus basse temperature que le regime gaussien, est tres bien decrit par la physique 2D de Kosterlitz-Thouless. Dans cette analyse, les deux regimes ont des temperatures critiques coherentes entre elles, ce qui semble confirmer ce scenario 2D. Une analyse des donnees dans le cadre de fluctuations 3D est exploree mais donne des conclusions incoherentes. Les resultats pour les autres dopages sont qualitativement equivalents avec le dopage optimal et permettent donc une explication purement 2D. Par contre, contrairement au dopage optimal

Increasing women’s sexual desire: The comparative effectiveness of estrogens and androgens

PubMed Central

Cappelletti, Maurand; Wallen, Kim

2016-01-01

Both estradiol and testosterone have been implicated as the steroid critical for modulating women’s sexual desire. By contrast, in all other female mammals only estradiol has been shown to be critical for female sexual motivation and behavior. Pharmaceutical companies have invested heavily in the development of androgen therapies for female sexual desire disorders, but today there are still no FDA approved androgen therapies for women. Nonetheless, testosterone is currently, and frequently, prescribed off-label for the treatment of low sexual desire in women, and the idea of testosterone as a cure-all for female sexual dysfunction remains popular. This paper places the ongoing debate concerning the hormonal modulation of women’s sexual desire within a historical context, and reviews controlled trials of estrogen and/or androgen therapies for low sexual desire in postmenopausal women. These studies demonstrate that estrogen-only therapies that produce periovulatory levels of circulating estradiol increase sexual desire in postmenopausal women. Testosterone at supraphysiological, but not at physiological, levels enhances the effectiveness of low-dose estrogen therapies at increasing women’s sexual desire; however, the mechanism by which supraphysiological testosterone increases women’s sexual desire in combination with an estrogen remains unknown. Because effective therapies require supraphysiological amounts of testosterone, it remains unclear whether endogenous testosterone contributes to the modulation of women’s sexual desire. The likelihood that an androgen-only clinical treatment will meaningfully increase women’s sexual desire is minimal, and the focus of pharmaceutical companies on the development of androgen therapies for the treatment of female sexual desire disorders is likely misplaced.

Patterns of workplace supervisor support desired by abused women.

The purpose of this study was to understand differences in patterns of supervisor support desired by female victims of intimate partner violence (IPV) and to examine whether the pattern of support desired at work is reflective of a woman's stage of change in the abusive relationship, IPV-related work interference, and IPV-related job reprimands or job loss. We conducted interviews in Spanish or English with adult women working in low-income jobs who had been physically or sexually abused by an intimate partner/ ex-partner in the past year ( N = 133). Cluster analysis revealed three distinct clusters that form a hierarchy of type of support wanted: those who desired limited support; those who desired confidential, time-off, and emotional support; and those who desired support in wide variety of ways from their supervisor. The clusters appeared to reflect stages of behavior change in an abusive relationship. Specifically, the limited-support cluster may represent an early precontemplation stage, with women reporting the least interference with work. The support-in-every-way cluster may represent later stages of change, in which women are breaking away from the abusive partner and report the greatest interference with work. Women in the confidential-, time-off-, and emotional-support cluster are in a transition stage in which they are considering change and are exploring options in their abusive relationship. Understanding the hierarchy of the type of support desired, and its relationship to stages of change in the abusive relationship and work interference, may provide a strong foundation for developing appropriate and effective workplace interventions to guide supervisors in providing support to women experiencing IPV.

Specification and [visual] modelling languages are expected to combine strong abstraction mechanisms with rigour, scalability, and parsimony. LePUS3 is a visual, object-oriented design description language axiomatized in a decidable subset of the first-order predicate logic. We demonstrate how LePUS3 is used to formally specify a structural design pattern and prove ( verify ) whether any JavaTM 1.4 program satisfies that specification. We also show how LePUS3 specifications (charts) are composed and how they are verified fully automatically in the Two-Tier Programming Toolkit.

Sexual arousal and desire: interrelations and responses to three modalities of sexual stimuli.

Goldey, Katherine L; van Anders, Sari M

Traditionally, sexual desire is understood to occur spontaneously, but more recent models propose that desire responds to sexual stimuli. To experimentally assess whether sexual stimuli increased sexual desire; to compare how sexual arousal and desire responded to three modalities of sexual stimuli: erotic story, unstructured fantasy, and the Imagined Social Situation Exercise (ISSE). In an online study, participants (128 women, 98 men) were randomly assigned to one of four arousal conditions (ISSE, story, fantasy, or neutral), and then completed desire measures. In the ISSE, participants imagined and wrote about a positive sexual encounter with a self-defined attractive person. Sexual arousal (perceived genital, psychological, and perceived autonomic), anxiety, positive and negative affect, and state sexual desire via self-report measures pre- and post-condition; "trait" desire via the Sexual Desire Inventory post-condition. All three sexual conditions significantly increased sexual arousal and positive affect compared with the neutral condition, with trends for higher arousal to unstructured fantasy than the ISSE or story conditions. Sexual conditions significantly increased scores on state measures of sexual desire. In addition, sexual context influenced measurement of "trait" solitary sexual desire in women, such that women reported significantly higher trait desire after the neutral and ISSE conditions vs. fantasy. Results highlight the responsiveness of sexual desire, problems with measurement of desire as a long-term trait, trade-offs of using the ISSE and other stimuli in sexuality research, and the need to address context in discussions of women's and men's desire. © 2012 International Society for Sexual Medicine.

Le Fort I Maxillary Advancement Using Distraction Osteogenesis

Combs, Patrick D.; Harshbarger, Raymond J.

2014-01-01

Treatment of maxillary hypoplasia has traditionally involved conventional Le Fort I osteotomies and advancement. Advancements of greater than 10 mm risk significant relapse. This risk is greater in the cleft lip and palate population, whose anatomy and soft tissue scarring from prior procedures contributes to instability of conventional maxillary advancement. Le Fort I advancement with distraction osteogenesis has emerged as viable, stable treatment modality correction of severe maxillary hypoplasia in cleft, syndromic, and noncleft patients. In this article, the authors provide a review of current data and recommendations concerning Le Fort I advancement with distraction osteogenesis. In addition, they outline their technique for treating severe maxillary hypoplasia with distraction osteogenesis using internal devices. PMID:25383054

Paralyzed by desire: a new type of body integrity identity disorder.

PubMed

Giummarra, Melita J; Bradshaw, John L; Hilti, Leonie M; Nicholls, Michael E R; Brugger, Peter

2012-03-01

Body incongruity in body integrity identity disorder (BIID) manifests in the desire to have a healthy limb amputated. We describe a variant of the disorder: the desire to become paralyzed (paralysis-BIID). Sixteen otherwise healthy participants, recruited through Internet-based forums, websites, or word of mouth, completed questionnaires about details of their desire and accompanying symptoms. Onset of the desire for paralysis typically preceded puberty. All participants indicated a specific level for desired spinal cord injury. All participants simulated paralysis through mental imagery or physical pretending, and 9 (56%) reported erotic interest in paraplegia and/or disability. Our key new finding was that 37.5% of paralysis-BIID participants were women, compared with 4.4% women in a sample of 68 individuals with amputation-BIID. BIID reflects a disunity between self and body, usually with a prominent sexual component. Sex-related differences are emerging: unlike men, a higher proportion of women desire paralysis than desire amputation, and, while men typically seek unilateral amputation, women typically seek bilateral amputation. We propose that these sex-related differences in BIID manifestation may relate to sex differences in cerebral lateralization, or to disruption of representation and/or processing of body-related information in right-hemisphere frontoparietal networks.

Specific role of LeMAN2 in the control of seed germination exposed by overexpression of the LeMAN3 gene in tomato plants.

PubMed

Belotserkovsky, Harel; Berger, Yael; Shahar, Ron; Wolf, Shmuel

2007-12-01

Endo-beta-mannanase is one of the key enzymes involved in the hydrolysis of the mannan-rich cell walls of tomato (Solanum lycopersicon) seeds. Two isoforms of endo-beta-mannanase have been characterized in tomato seeds: LeMAN2 is active in the micropylar area prior to germination and LeMAN1 is active after germination in all endosperm cells surrounding the cotyledons. To explore whether general mannanase activity in the endosperm cap is sufficient to promote germination, the gene encoding LeMAN3 was inserted into transgenic tomato plants under the control of a CaMV-35S promoter. Expression of LeMAN3 was evident in the endosperm cap and in the lateral endosperm of the transgenic seeds 10 min after imbibition. An activity test indicated increased activity of endo-beta-mannanase in the transgenic lines relative to the control line in all seed parts, during the first 20 h of imbibition. However, overexpression of LeMAN3 in transgenic seeds inhibited seed germination at both optimal and suboptimal temperatures. Detailed RT-PCR analyses revealed the transcription patterns of the genes encoding the various mannanase isoforms, and indicated a delay in LeMAN2 transcription in the endosperm cap of the transgenic seeds. Interestingly, tissue-print assays indicated similar mannanase activity in the micropylar areas for both transgenic and control seeds. These results indicate that overexpression of active endo-beta-mannanase in the endosperm cap is not sufficient to enable hydrolysis of the cell walls or to promote germination of tomato seeds. Cell-wall hydrolysis in these endosperm cells is under tight control and requires the specific activity of LeMAN2.

Social desirability response bias and dietary inventory responses.

Worsley, A; Baghurst, K I; Leitch, D R

1984-02-01

Royal Australian Air Force recruits completed a dietary frequency inventory (n = 309), a short social desirability inventory phrased in dietary terms (SDF, n = 309), and, in addition, a subsample answered the Marlow-Crowne social desirability scale (n = 96). Correlational and factor analyses showed that the SDF scores were related to the MC scale; and, the scores on the SDF scale were significantly related to the reported consumption of fresh fruit and vegetables and snack foods. In a further study, 20 lay persons were asked to sort the 66 foods listed in the dietary inventory into three categories: nutritionist-approved foods; nutritionist-disapproved foods; and, an 'uncertain' category. The results confirmed the finding that fresh fruit and vegetables were socially desirable foods, but sweet foods were not. It is concluded that social approval needs may influence the manner in which individuals report their consumption of these foods.

Eating behaviour among nutrition students and social desirability as a confounder.

2017-06-01

The study of eating behaviour should consider the presence of potential sources of bias, including social desirability. This is particularly relevant among students of Nutrition Sciences, since they have a higher risk of eating disorders. To analyse the effect of social desirability in the assessment of eating behaviour dimensions among nutrition students. In this cross-sectional study, we analysed data from 149 students of Nutrition Sciences. Participants completed a questionnaire assessing social desirability and eating behaviour dimensions (emotional, external and binge eating, flexible and rigid control, and eating self-efficacy). Among males, social desirability had a negative association with binge eating, while among women it had a negative association with emotional, external and binge eating and a positive association with eating self-efficacy. In both subsamples, social desirability showed no significant association with any of the two types of dietary restraint (rigid and flexible control). Overall, the association between social desirability and eating behaviour dimensions among students of Nutrition Sciences occurs in the same direction as found in students from other areas. However, alongside these similarities, there is a stronger association between social desirability and binge eating among male students of Nutrition Sciences. We hypothesize that this may be related with the different knowledge of students from different areas, and the way they perceive and face the treatment of eating disorders. Our study shows that social desirability should be considered while assessing eating behaviour among nutrition students, particularly when studying external eating, binge eating and eating self-efficacy. Moreover, when tailoring interventions to reduce the possible effects of eating behaviour on nutritionists and dieticians' practice, we should consider the influence of social desirability.

The scope of the LeChatelier Principle

George M., Lady; Quirk, James P.

2007-07-01

LeChatelier [Comptes Rendus 99 (1884) 786; Ann. Mines 13 (2) (1888) 157] showed that a physical system's “adjustment” to a disturbance to its equilibrium tended to be smaller as constraints were added to the adjustment process. Samuelson [Foundations of Economic Analysis, Harvard University Press, Cambridge, 1947] applied this result to economics in the context of the comparative statics of the actions of individual agents characterized as the solutions to optimization problems; and later (1960), extended the application of the Principle to a stable, multi-market equilibrium and the case of all commodities gross substitutes [e.g., L. Metzler, Stability of multiple markets: the hicks conditions. Econometrica 13 (1945) 277-292]. Refinements and alternative routes of derivation have appeared in the literature since then, e.g., Silberberg [The LeChatelier Principle as a corollary to a generalized envelope theorem, J. Econ. Theory 3 (1971) 146-155; A revision of comparative statics methodology in economics, or, how to do comparative statics on the back of an envelope, J. Econ. Theory 7 (1974) 159-172], Milgrom and Roberts [The LeChatelier Principle, Am. Econ. Rev. 86 (1996) 173-179], W. Suen, E. Silberberg, P. Tseng [The LeChatelier Principle: the long and the short of it, Econ. Theory 16 (2000) 471-476], and Chavas [A global analysis of constrained behavior: the LeChatelier Principle ‘in the large’, South. Econ. J. 72 (3) (2006) 627-644]. In this paper, we expand the scope of the Principle in various ways keyed to Samuelson's proposed means of testing comparative statics results (optimization, stability, and qualitative analysis). In the optimization framework, we show that the converse LeChatelier Principle also can be found in constrained optimization problems and for not initially “conjugate” sensitivities. We then show how the Principle and its converse can be found through the qualitative analysis of any linear system. In these terms, the Principle and

Ultrafast intramolecular charge transfer with N-(4-cyanophenyl)carbazole. Evidence for a LE precursor and dual LE + ICT fluorescence.

2010-12-09

The photophysics of N-(4-cyanophenyl)carbazole (NP4CN) was investigated by using absorption and fluorescence spectra, picosecond fluorescence decays, and femtosecond transient absorption. In the nonpolar n-hexane as well as in the polar solvent acetonitrile (MeCN), a locally excited (LE) state is detected, as a precursor for the intramolecular charge transfer (ICT) state. A LE → ICT reaction time τ(2) at 22 °C of 0.95 ps in ethyl cyanide (EtCN) and 0.32 ps in MeCN is determined from the decay of the LE excited state absorption (ESA) maximum around 620 nm. In the ESA spectrum of NP4CN in n-hexane at a pump-probe delay time of 100 ps, an important contribution of the LE band remains alongside the ICT band, in contrast to what is observed in EtCN and MeCN. This shows that a LE ⇄ ICT equilibrium is established in this solvent and the ICT reaction time of 0.5 ps is equal to the reciprocal of the sum of the forward and backward ICT rate constants 1/(k(a) + k(d)). In the photostationary S(0) → S(n) absorption spectrum of NP4CN in n-hexane and MeCN, an additional CT absorption band appears, absent in the sum of the spectra of its electron donor (D) and acceptor (A) subgroups carbazole and benzonitrile. This CT band is located at an energy of ∼4000 cm(-1) lower than for N-phenylcarbazole (NPC), due to the larger electron affinity of the benzonitrile moiety of NP4CN than the phenyl subunit of NPC. The fluorescence spectrum of NP4CN in n-hexane at 25 °C mainly consists of a structured LE emission, with a small ICT admixture, indicating that a LE → ICT reaction just starts to occur under these conditions. In di-n-pentyl ether (DPeE) and di-n-butyl ether (DBE), a LE emission is found upon cooling at the high-energy edge of the ICT fluorescence band, caused by the onset of dielectric solvent relaxation. This is not the case in more polar solvents, such as diethyl ether (DEE) and MeCN, in which a structureless ICT emission band fully overlaps the strongly quenched LE

Normativity and Desirability in Observational Assessments of Family Interaction.

PubMed

Deal, James E

2018-06-11

Issues of normativity (responding in a typical or average fashion) and desirability (the tendency for raters to endorse positive characteristics rather than neutral or more negative ones) are common in areas of the social sciences that frequently utilize profile correlations to measure dyadic similarity. They have implications for family scholars as well. In the present study, a pre-existing data set was used to make an initial, though limited, investigation into potential confounds of normativity and desirability for macrolevel observational assessments of family interaction. An empirical example is presented using q-sort ratings of family interaction, with variance in observational assessments decomposed into component parts. High levels of both normativity and desirability were found, indicating possible problems in terms of both reliability and validity of assessment. While the results provide an interesting beginning, they are limited due to the use of a q-sort methodology as well as an instrument with limited background and use. These limitations are discussed, as well as alternative interpretations for normativity and desirability and implications for future research. © 2018 Family Process Institute.

Time under control: time perspective and desire for control in substance use.

Fieulaine, Nicolas; Martinez, Frederic

To investigate the role of time perspective and desire for control in self-reported substance use and to test for a moderating effect of desire for control in the relation between time perspective and substance use. A random sample of 240 persons, aged 15 years and over, selected in various public spaces in an urban region in central France. Time perspective was measured using subscales of the Zimbardo Time Perspective Inventory (ZTPI, Zimbardo & Boyd, 1999), Desire for control was measured using a translated version of the Desire for Control Scale (DCS, Burger & Cooper, 1979), and substance use was self-reported. After controlling for age and gender, significant links were found between time perspective and substance use. Desire for control did not appear to be directly related to substance use. The interaction effect between TP and desire for control appeared to be related to substance use. There was evidence that the relation between TP and substance use is buffered by low desire for control. This study converges with previous studies demonstrating the relation between TP and substance use, but provides evidence of the moderating role played by desire for control. Desire for control thus appears as worthy of interest in the analysis of self-regulatory process, and further research on the links between TP and various aspects of control is required. In order to be more effective, the design of future studies and interventions based on time-related issues should consider how desire for control plays a part in establishing vulnerability profiles.

Objectif Expliquer la présentation clinique, les observations à l’examen physique, les critères diagnostiques et les options de prise en charge du conflit fémoroacétabulaire (CFA). Sources des données Une recherche documentaire a été effectuée dans PubMed pour trouver des articles pertinents sur la pathogenèse, le diagnostic, le traitement et le pronostic du CFA. Message principal Depuis les dernières années, on reconnaît de plus en plus que le CFA est un précurseur potentiel et une étiologie importante des douleurs à la hanche dans la population adulte et de la coxarthrose idiopathique plus tard dans la vie. Le conflit fémoro-acétabulaire désigne un ensemble d’anomalies morphologiques osseuses de l’articulation de la hanche qui se traduit par un contact anormal durant le mouvement. Le CFA par effet came concerne une proéminence osseuse non sphérique du col fémoral proximal ou de la jonction tête-col. Le CFM par effet tenaille désigne une couverture acétabulaire excessive par-dessus la tête du fémur, qui peut se produire en raison de diverses variantes morphologiques. Les patients qui ont un CFA présentent une douleur inguinale antérieure chronique, profonde ou lancinante, le plus souvent en position assise, durant ou après une activité. Les patients peuvent aussi ressentir des douleurs occasionnelles aiguës durant l’activité. Il faut procéder à une anamnèse approfondie portant notamment sur l’incidence de traumatismes ou la fréquence de l’exercice. Il faut aussi faire un examen physique complet des hanches, de la région lombaire et de l’abdomen pour évaluer d’autres causes de douleurs inguinales antérieures. Le diagnostic de CFA est confirmé par radiographie. Le conflit fémoro-acétabulaire peut être pris en charge selon une approche conservatrice comportant du repos, la modification des activités, des médicaments et de la physiothérapie ou encore être traité par intervention chirurgicale.

High healthcare cost has drawn much attention and healthcare service providers (HSPs) are expected to deliver high-quality and consistent care. Therefore, an intimate understanding of the most desirable experience from a patient's and/or family's perspective as well as effective mapping and communication of such findings should facilitate HSPs' efforts in attaining sustainable competitive advantage in an increasingly discerning environment. This study describes (a) the critical quality attributes (CQAs) of the experience desired by patients and (b) the application of two visualization tools that are relatively new to the healthcare sector, namely the "spider-web diagram" and "promotion and detraction matrix." The visualization tools are tested with primary data collected from telephone surveys of 1,800 patients who had received care during calendar year 2005 at 6 of 61 hospitals within St. Louis, Missouri-based, Ascension Health. Five CQAs were found by factor analysis. The spider-web diagram illustrates that communication and empowerment and compassionate and respectful care are the most important CQAs, and accordingly, the promotion and detraction matrix shows those attributes that have the greatest effect for creating promoters, preventing detractors, and improving consumer's likelihood to recommend the healthcare provider.

In the current study we explored the role of desire thinking in predicting binge eating independently of Body Mass Index, negative affect and irrational food beliefs. A sample of binge eaters (n=77) and a sample of non-binge eaters (n=185) completed the following self-report instruments: Hospital Anxiety and Depression Scale, Irrational Food Beliefs Scale, Desire Thinking Questionnaire, and Binge Eating Scale. Mann-Whitney U tests revealed that all variable scores were significantly higher for binge eaters than non-binge eaters. A logistic regression analysis indicated that verbal perseveration was a predictor of classification as a binge eater over and above Body Mass Index, negative affect and irrational food beliefs. A hierarchical regression analysis, on the combined sample, indicated that verbal perseveration predicted levels of binge eating independently of Body Mass Index, negative affect and irrational food beliefs. These results highlight the possible role of desire thinking as a risk factor for binge eating. Copyright © 2015 Elsevier Ltd. All rights reserved.

The Lived Experiences of Sexual Desire Among Chinese-Canadian Men and Women.

2017-05-19

How North American Chinese conceptualize and experience sexual desire is not well understood, and may have implications for understanding cross-cultural differences in sexual functioning. This study examined narratives of sexual desire among Chinese men and women in Canada. Ten each of Chinese men (age: M = 24.0, range = 18-42) and women (age: M = 23.5, range = 19-38) took part in semi-structured interviews in which they were invited to share personal accounts of sexual desire. A phenomenological analysis of participants' responses showed men and women described desire as having genital, nongenital-physical, and cognitive-emotional components. Chinese cultural prohibitions against sexuality, particularly pronounced in women, were a common inhibitor of desire. Relationship factors appeared as a frequently endorsed context and target of desire. These findings suggest that relationship context is of paramount importance in Chinese individuals and that previous findings of low sexual functioning in this group may be due to inhibition from cultural factors. However, the experience of desire in Chinese individuals is also in many ways similar to that of existing conceptualizations from Western samples.

Synthetic chromosome rearrangement and modification by loxP-mediated evolution (SCRaMbLE) generates combinatorial genomic diversity through rearrangements at designed recombinase sites. We applied SCRaMbLE to yeast synthetic chromosome arm synIXR (43 recombinase sites) and then used a computational pipeline to infer or unscramble the sequence of recombinations that created the observed genomes. Deep sequencing of 64 synIXR SCRaMbLE strains revealed 156 deletions, 89 inversions, 94 duplications, and 55 additional complex rearrangements; several duplications are consistent with a double rolling circle mechanism. Every SCRaMbLE strain was unique, validating the capability of SCRaMbLE to explore a diverse space of genomes. Rearrangements occurred exclusively at designed loxPsym sites, with no significant evidence for ectopic rearrangements or mutations involving synthetic regions, the 99% nonsynthetic nuclear genome, or the mitochondrial genome. Deletion frequencies identified genes required for viability or fast growth. Replacement of 3' UTR by non-UTR sequence had surprisingly little effect on fitness. SCRaMbLE generates genome diversity in designated regions, reveals fitness constraints, and should scale to simultaneous evolution of multiple synthetic chromosomes. © 2016 Shen et al.; Published by Cold Spring Harbor Laboratory Press.

Ces travaux entrent dans le cadre des études nécessaires à la mise au point d'une structure déformable actionnée par fils en alliage à mémoire de forme. L'application visée est son utilisation comme module de locomotion d'un microrobot intratubulaire autonome de type “ lombric ”. Un module est constitué d'un cadre élastique carré forcé en post-flambement sur un squelette rigide, de manière à obtenir deux configurations symétriques d'équilibre stable correspondant au premier mode de flambage. Le passage d'un état d'équilibre à l'autre est obtenu par la contraction de fils AMF éduqués disposés sur le cadre post-flambé. Un assemblage par juxtaposition de cinq modules identiques compose le corps du microrobot. Suivant un cycle de locomotion adéquat, chacun de ces actionneurs “ tout ou rien ” permet la prise d'appui sur les parois du tube ou l'allongement local nécessaire à l'avance du microrobot. Nous présentons ici les résultats obtenus lors d'un chargement transversal d'un module, et en particulier les courbes reliant l'effort de réaction et le déplacement du point en contact avec le tube. L'influence du serrage subit par le module sur le maintien du microrobot dans un tube vertical est déterminée. Les résultats expérimentaux obtenus sont comparés avec les résultats numériques.

2016-04-01

Hospitalised haematological cancer patients often suffer from reduced appetite and food intake, which negatively influences the patients' well-being and nutritional status. The aim of this study was to identify specific between-meal food desires in a patient group, in order to increase food intake. The study was conducted using a picture-aided questionnaire, and relating the preferences to factors that could easily be implemented in the hospital menu, such as time of the day and texture. Moreover, the results of the questionnaire were verified by acceptance tests on six selected food items. A structured 42 items food questionnaire was developed and used to quantify appetitive food desires in patients during morning (11 am) and afternoon (3 pm) sessions. Food items were scored according to patients' preferences and immediate desire to eat. A total of 112 hospitalised haematological cancer patients, screened for nutrition-related symptoms, participated. Univariate statistical models were used to investigate the influence of time-of-day and food texture on between-meal desires. Fresh fruit, ice cream, cheese and mashed potatoes with bacon were the most desired food items. Patients showed significant higher desire to eat in the morning as opposed to the afternoon. Moreover, texture had an influence on food desire, where liquid food was more desired than food with soft or coarse texture. Ranking of food desires among hospitalised cancer patients showed inclination for fresh fruit, ice cream, mashed potatoes with bacon, and cheese. Time of the day (morning) and texture (liquid) had the greatest and most positive impact on food desires. The findings may be easily implemented in hospital food service routines for cancer patients, and might positively contribute to patients' well-being and nutrition.

Desirable attributes of public educational websites.

PubMed

Whitbeck, Caroline

2005-07-01

Certain attributes are particularly desirable for public educational websites, and websites for ethics education in particular. Among the most important of these attributes is wide accessibility through adherence to the World Wide Web Consortium (W3C) standards for HTML code. Adherence to this standard produces webpages that can be rendered by a full range of web browsers, including Braille and speech browsers. Although almost no academic websites, including ethics websites, and even fewer commercial websites are accessible by W3C standards, as illustrated by the Online Ethics Center for Engineering and Science , even websites created on limited budgets and with an undergraduate student staff can fulfill these standards. Other desirable attributes, such as provision of annotation for all links and the use of annotated links to give the user alternate ways of ordering and organizing content, are important for making full use of the educational possibilities of hypermedia for websites.

The Heart Trumps the Head: Desirability Bias in Political Belief Revision

PubMed Central

2017-01-01

Understanding how individuals revise their political beliefs has important implications for society. In a preregistered study (N = 900), we experimentally separated the predictions of 2 leading theories of human belief revision—desirability bias and confirmation bias—in the context of the 2016 U.S. presidential election. Participants indicated who they desired to win, and who they believed would win, the election. Following confrontation with evidence that was either consistent or inconsistent with their desires or beliefs, they again indicated who they believed would win. We observed a robust desirability bias—individuals updated their beliefs more if the evidence was consistent (vs. inconsistent) with their desired outcome. This bias was independent of whether the evidence was consistent or inconsistent with their prior beliefs. In contrast, we found limited evidence of an independent confirmation bias in belief updating. These results have implications for the relevant psychological theories and for political belief revision in practice. PMID:28557511

Disentangling prototypicality and social desirability: the case of the KNOWI task.

PubMed

Turan, Bulent

2011-01-01

The prototype of indicators of a relationship partner who can be trusted to be responsive at times of stress is one kind of social knowledge structure. The Knowledge of Indicators (KNOWI) Task assesses individual differences in knowledge about these prototypic indicators. In constructing the KNOWI, an iterative procedure was used in an attempt to identify those indicators for which ratings of prototypicality are not influenced by social desirability. Study 1 demonstrated that the correlation between ratings of prototypicality and social desirability is indeed eliminated for the final set of indicators retained in the KNOWI. Study 2 tested the prototype matching hypothesis: Comparing an actual partner to the prototype might shape global judgments about that partner's responsiveness. Because in Study 2 only those indicators that are uncorrelated with social desirability were used, this result cannot be explained by social desirability. These results support the construct validity of the indicators used in the KNOWI Task, which seems to be a precise assessment tool not influenced by social desirability.

Perceptions of desirable graduate competencies for science and technology new graduates

NASA Astrophysics Data System (ADS)

Coll, Richard K.; Zegwaard, Karsten E.

2006-05-01

Work-integrated learning (WIL) programmes that combine on-campus classroom-based study with off-campus authentic work experience are a growing area of interest internationally. Despite widespread practice of WIL, there are few reports that shed light on appropriate pedagogies for the work experience in particular. As with any form of education, providers hold certain views as to desirable outcomes in terms of graduate profiles and of desirable graduate competencies. A complication for multi-party WIL programmes is that educational stakeholders (e.g., staff working in tertiary education provider institutions and employers) may hold different views as to desirable graduate competencies. Here we argue that an understanding of stakeholder views of desirable graduate competencies is an essential prerequisite of pedagogical design. The research reported here is an intrinsic case study and comprised an investigation of perceptions of 24 desirable graduate competencies for new science and technology graduates entering the workforce both today, and in ten years’ time. Stakeholders for four sector stakeholder groups (n = 458): undergraduate students (n = 71), recent graduates (n = 143), employers of graduates (n = 172), and faculty (n = 72), were surveyed using a previously reported and validated instrument. The research findings suggest that science and technology stakeholders see all 24 competencies as desirable, and see the importance of all skills and some skills in particular as likely to increase in ten years’ time. Despite emphasis on cognitive and technical skills (often termed ‘hard’ skills), the single most desirable skill is ability and willingness to learn, a behavioural skill (often termed ‘soft’ skills). It is proposed that classroom-based instruction is unlikely to produce graduates with the desired skills, and that work-integrated learning may have a role to play in the development of graduate competencies.

The DSM diagnostic criteria for Hypoactive Sexual Desire Disorder in men.

PubMed

Brotto, Lori A

2010-06-01

Hypoactive Sexual Desire Disorder (HSDD) is one of two sexual desire disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and is defined by two criteria: A-"persistently or recurrently deficient (or absent) sexual fantasies and desire for sexual activity" and B-"marked distress or interpersonal difficulty." This paper reviews the prevalence and correlates of low desire in men and qualitative and quantitative research on the experience of sexual desire in men and women. A literature search of Medline, PudMed, and PsychInfo was used to identify any publication on low desire in men. The strength of empirical findings was used as a basis for making proposed revisions to the diagnostic criteria for HSDD in men. The dilemma of whether desire and arousal can be reliably differentiated in men is discussed, and parallels to the literature in women are drawn. Finally, I consider three options for the diagnosis of low desire in men for DSM-5. Option 1 proposes that the DSM-IV-TR name and criteria are preserved for men in DSM-5. Option 2 proposes that the recently proposed criteria for Sexual Interest/Arousal Disorder in women are also adopted for men, which would result in one gender-neutral category. Option 3 proposes that the criteria for Sexual Interest/Arousal Disorder also be applied to men, with a minor modification to one criterion (i.e., that absent or reduced genital and/or nongenital physical changes not be included as a criterion); this diagnosis would then be applied only to men. The evidence supporting each of these proposals is presented and critiqued. It is concluded that the proposal for DSM-5 should be made on the basis of field testing of new criteria.

Eating behavior in Portuguese higher education students: the effect of social desirability.

PubMed

Poínhos, Rui; Oliveira, Bruno M P M; Correia, Flora

2015-02-01

The aim of this study was to relate social desirability with eating behavior dimensions among higher education students in Portugal, and to assess the effect of social desirability on the association between pairs of eating behavior dimensions. Data from 266 higher education students (62.8% women) aged between 18 and 27 y were evaluated. Social desirability and several eating behavior dimensions (emotional and external eating, flexible and rigid restraint, binge eating, and eating self-efficacy) were assessed. In both women and men, social desirability showed negative associations with emotional, external, and binge eating, and positive associations with eating self-efficacy. For the majority of the correlations, the control for social desirability led to a decrease in the strength of the association: Social desirability showed a greater effect on the associations between external and binge eating, external eating and eating self-efficacy, binge eating and eating self-efficacy, and emotional and external eating. This study demonstrated that social desirability should be considered when assessing the dimensions of eating behavior, namely eating self-efficacy and dimensions related to overeating.

Le Fort-type fractures are very rare in children, and there is a paucity of literature presenting their frequency and characteristics. The purpose of this study was to determine the etiology, frequency, and fracture patterns of children with severe facial trauma associated with pterygoid plate fractures in a pediatric cohort. We performed a retrospective cohort study of all children aged younger than 16 years with pterygoid plate and facial fractures who presented to our institute between 1990 and 2010. Patient charts and radiologic records were reviewed for demographic and fracture characteristics. Patients were categorized into 2 groups as per facial fracture pattern: non-Le Fort-type fractures (group A) and Le Fort-type fractures (group B). Other variables including dentition age, frontal sinus development, mechanism of injury, injury severity, and concomitant injuries were recorded. Univariate methods were used to compare groups. We identified 24 children; 25% were girls, and 20.8% were of nonwhite race. Most presented with Le Fort-type fracture patterns (group B, 66.7%). Age was significantly different between group A and group B (mean, 5.9 years and 9.9 years, respectively; P = .009). No significant differences in Injury Severity Score, rate of operative repair, and length of stay were found between groups. Most children with severe facial fractures and pterygoid plate fractures presented with Le Fort-type fracture patterns in our cohort. The mean age of children with Le Fort-type fractures was greater than in those with non-Le Fort-type patterns. However, Le Fort-type fractures did occur in younger children with deciduous and mixed dentition. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

Le tabagisme et la tuberculose sont deux enjeux majeurs de santé publique au niveau mondial, en particulier dans les pays émergents. Pour déterminer les particularités cliniques, radiologiques, bactériologiques et thérapeutiques de la tuberculose pulmonaire chez les sujets tabagiques nous avons mené une étude prospective au service de phtisiologie de l'hôpital Moulay Youssef sur une période de 10 mois, portant sur 100 nouveaux cas de tuberculose pulmonaire, répartis en 2 groupes, 50 patients tabagiques: Groupe A et 50 patients non tabagiques: Groupe B. Tous nos patients étaient de sexe masculin, l’âge moyen était de 41 ans ± 12 chez le groupe A et de 36 ans ± 16 chez le groupe B. Le délai de consultation était plus long chez les tabagiques, la médiane était de 60j (30; 98) contre 40j (30; 60), la symptomatologie clinique était variable chez les deux groupes, dominée par les expectorations chez les tabagiques 96% contre 60%. Les lésions radiologiques étaient similaires chez les deux groupes ainsi que la charge bacillaire. Tous les patients ont été mis sous traitement antituberculeux. Après un mois du traitement, la Bacilloscopie était négative chez 50% du groupe A contre 66% chez le groupe B. la régression des lésions radiologiques était similaire chez les deux groupes. Le retard diagnostique et le retard de négativation des frottis sont les principales particularités de la tuberculose pulmonaire du sujet tabagique. Le sevrage tabagique doit faire partie intégrante de la prise en charge des patients atteints de tuberculose. PMID:25821545

Socially desirable responding and impression management in the endorsement of love styles.

PubMed

Davies, M F

2001-09-01

In 2 experiments, the researcher investigated the social desirability of different love styles (Eros, Ludus, Storge, Pragma, Mania, and Agape). In Experiment 1, the Marlowe-Crowne measure of social desirability (D. P. Crowne & D. Marlowe, 1960) was correlated negatively with possessive, dependent (Mania) love styles in both men and women. In men, social desirability was correlated positively with romantic, passionate love (Eros) and game-playing love (Ludus), but negatively with all-giving, selfless love (Agape). In women, social desirability was correlated positively with Agape, but negatively with Ludus. In Experiment 2, the researcher replicated these findings using an impression management manipulation (good, bad, and honest responding). The gender differences in social desirability of different love styles are explained in terms of traditional and nontraditional gender role socialization.

Son preference, fertility desire and contraceptive use in two largest cities of Pakistan.

PubMed

Farooqui, M N

1990-01-01

The preference for sons in deeprooted in Pakistan and the growth rate is 3.1%/year, which has long term implications for the Population Welfare Program. In this study, the relationship between living sons and contraceptive use is examined among 1243 currently married industrial workers and 307 control group workers from 13 sample industries in Karachi and Lahore, Pakistan. The Family Welfare Education for Workers' Project has been operating in these industries. Questions were asked about the number of living children by sex, desired number of children by sex, and ideal family size by sex. The ideal number of children was 4 (3.7) with an average of 2.2 sons and 1.5 daughters, which indicates son preference. Average desired children (living plus additional wanted) is 5.0 (4.7) with an average of 2.6 for sons and 2.1 for daughters. All workers with an ideal of 1 wanted a son. 90% of those wanting an ideal of 2 children desired 1 son and 1 daughter. 95% with an ideal of 3 children wanted 2 sons and 1 daughter. 83% with an ideal of 4 children desired 2 sons and 2 daughters, and 16% wanted 3 sons and 1 daughter. 85% with an ideal of 5 children wanted 3 sons and 2 daughters. Further evidence for son preference occurs with total desired number of children; i.e., 79% of those desiring 2 children preferred 1 of each sex, and 21%, 2 sons. This pattern was repeated for each increase in child desired. The desire for children was also examined in terms of existing children. Workers who have more sons were less likely to desire another child; however, those with 2 living daughters desired 1.63 more children and those with 1 of each desired .85 more children. Those with 2 sons desired .67 more children. The number of additional children desired decreases with the increasing number of living children, and with increasing numbers of living sons. Desiring no more children tends to increase with an increase in number of living children, and with an increase in the number of living

Average Associations Between Sexual Desire, Testosterone, and Stress in Women and Men Over Time.

Raisanen, Jessica C; Chadwick, Sara B; Michalak, Nicholas; van Anders, Sari M

2018-05-29

Sexual desire and testosterone are widely assumed to be directly and positively linked to each other despite the lack of supporting empirical evidence. The literature that does exist is mixed, which may result from a conflation of solitary and dyadic desire, and the exclusion of contextual variables, like stress, known to be relevant. Here, we use the Steroid/Peptide Theory of Social Bonds as a framework for examining how testosterone, solitary and partnered desire, and stress are linked over time. To do so, we collected saliva samples (for testosterone and cortisol) and measured desire as well as other variables via questionnaires over nine monthly sessions in 78 women and 79 men. Linear mixed models showed that testosterone negatively predicted partnered desire in women but not men. Stress moderated associations between testosterone and solitary desire in both women and men, but differently: At lower levels of stress, higher average testosterone corresponded to higher average solitary desire for men, but lower solitary desire on average for women. Similarly, for partnered desire, higher perceived stress predicted lower desire for women, but higher desire for men. We conclude by discussing the ways that these results both counter presumptions about testosterone and desire but fit with the existing literature and theory, and highlight the empirical importance of stress and gender norms.

Suppressing smoking thoughts has been shown to result in elevated smoking. However, the effect of suppressing smoking thoughts on desire to smoke and withdrawal symptoms has not been investigated. We examined the effects of suppressing smoking thoughts on the subsequent desire to smoke and on tobacco withdrawal symptoms, relative to groups that were either thinking about anything they wished or actively thinking about smoking. A randomised experimental study compared the effects of three manipulations (suppressed smoking thoughts, expressed smoking thoughts and thoughts of anything they wished) on desire and withdrawal immediately after the manipulation and 5 and 10 min after. Suppressing smoking thoughts did not result in elevated subsequent desire to smoke, relative to the other manipulations. Suppressing smoking thoughts resulted in a significant elevation in hunger ratings, relative to the other manipulations, at all measurement times. There were no significant effects for the other withdrawal symptoms. Self-reported greater use of thought suppression in everyday life was significantly associated with greater desire to smoke at baseline and was associated with lower mindfulness scores. Laboratory-instructed suppression of smoking thoughts is associated with increased reports of hunger but did not lead to increases in other withdrawal symptoms or elevated desire to smoke. Reports of everyday use of thought suppression are associated with elevated desire to smoke at baseline. Further investigations need to assess the effect of suppressing smoking cravings, instead of general smoking thoughts, on desire to smoke and tobacco withdrawal.

Desirability function combining metabolic stability and functionality of peptides.

Van Dorpe, Sylvia; Adriaens, Antita; Vermeire, Simon; Polis, Ingeborgh; Peremans, Kathelijne; Spiegeleer, Bart De

2011-05-01

The evaluation of peptides as potential therapeutic or diagnostic agents requires the consideration of several criteria that are targeted around two axes: functionality and metabolic stability. Most often, a compromise has to be made between these mutually opposing characteristics. In this study, Derringer's desirability function, a multi-criteria decision-making method, was applied to determine the best peptide for opioid studies in a single figure-of-merit. The penetration of the blood-brain barrier (BBB) determines the biological functionality of neuropeptides in the brain target tissue, and consists of an influx and an efflux component. The metabolic stability in the two concerned tissues, i.e. plasma and brain, are taken into consideration as well. The overall selection of the peptide drug candidate having the highest BBB-drugability is difficult due to these conflicting responses as well as the different scalings of the four biological parameters under consideration. The highest desirability, representing the best BBB-drugability, was observed for dermorphin. This peptide is thus the most promising drug candidate from the set of eight opioid peptides that were investigated. The least desirable candidate, with the worst BBB influx and/or metabolic stability, was found to be CTAP. Validation of the desirability function by in vivo medical imaging showed that dermorphin and DAMGO penetrate the BBB, whereas EM-1 and TAPP did not. These results are thus consistent with those obtained with the desirability evaluation. To conclude, the multi-criteria decision method was proven to be useful in biomedical research, where a selection of the best candidate based on opposing characteristics is often required.

Research suggests that the desire to behave sexually with a partner (dyadic sexual desire) may reflect desire for intimacy whereas solitary sexual desire may reflect pleasure seeking motivations more generally. Because direct reproductive success can only be increased with a sexual partner, we tested whether dyadic sexual desire was a better predictor of women's preferences for lower pitched men's voices (a marker of relatively high reproductive success) than was solitary sexual desire. In Study 1, women (N = 95) with higher dyadic sexual desire scores on the Sexual Desire Inventory-2 preferred masculinized male voices more than did women with lower dyadic sexual desire scores. We did not find a significant relationship between women's vocal masculinity preferences and their solitary sexual desire scores. In Study 2, we tested whether the relationship between voice preferences and dyadic sexual desire scores was related to differences in sociosexual orientation. Women (N = 80) with more positive attitudes towards uncommitted sex had stronger vocal masculinity preferences regardless of whether men's attractiveness was judged for short-term or long-term relationships. Independent of the effect of sociosexual attitudes, dyadic sexual desire positively predicted women's masculinity preferences when assessing men's attractiveness for short-term but not long-term relationships. These effects were independent of women's own relationship status and hormonal contraceptive use. Our results provide further evidence that women's mate preferences may independently reflect individual differences in both sexual desire and openness to short-term relationships, potentially with the ultimate function of maximizing the fitness benefits of women's mate choices.

HISTORIQUE : De 20 % à 30 % des Canadiens qui vivent avec le VIH sont co-infectés par le virus de l’hépatite C (VHC), lequel est responsable d’une morbidité et d’une mortalité importantes. La prise en charge du VIH et du VHC est plus complexe en raison de l’évolution accélérée de la maladie hépatique, du choix et des critères d’initiation de la thérapie antirétrovirale et du traitement anti-VHC, de la prise en charge de la santé mentale et des toxicomanies, des obstacles socioéconomiques et des interactions entre les nouvelles thérapies antivirales à action directe du VHC et les antirétroviraux OBJECTIF : Élaborer des normes nationales de prise en charge des adultes co-infectés par le VHC et le VIH dans le contexte canadien. MÉTHODOLOGIE : Le Réseau canadien pour les essais VIH des Instituts de recherche en santé du Canada a réuni un groupe d’experts possédant des compétences cliniques en co-infection par le VIH et le VHC pour réviser les publications à jour ainsi que les lignes directrices et les protocoles en place. Après une vaste sollicitation afin d’obtenir des points de vue, le groupe de travail a approuvé des recommandations consensuelles, qu’il a caractérisées au moyen d’une échelle de qualité des preuves fondée sur la classe (bienfaits par rapport aux préjudices) et sur la catégorie (degré de certitude). RÉSULTATS : Toutes les personnes co-infectées par le VIH et le VHC devraient subir une évaluation en vue de recevoir un traitement du VHC. Les personnes qui ne sont pas en mesure d’entreprendre un traitement du VHC devraient être soignées pour le VIH afin de ralentir l’évolution de la maladie hépatique. La norme de traitement du VHC de génotype 1 est un régime comprenant de l’interféron pégylé et de la ribavirine dosée en fonction du poids, associés à un inhibiteur de la protéase du VHC. Pour les génotypes 2 ou 3, une bithérapie classique est recommandée pendant 24 semaines s�

Rôle de l'hydrogène dans le procédé de purification du silicium par plasma thermique inductif

The use of the thermal process for purification of silicon led to a material with the chemical purity required for phototovoltaic applications. In this paper, the various properties of ArH2 plasma mixtures are briefly reviewed and the effect of hydrogen percentage in an argon plasma used for melting and purifying silicon is pointed out. Physico-chemical analysis of the purified silicon showed that hydrogen diffused in the material and could passivate crystal defects by formation of stable chemical bonds such as Si-H. La technique de purification du silicium sous plasma thermique permet d'aboutir à un matériau de pureté chimique requise pour l'industrie photovoltaïque. Dans ce travail, nous soulignerons le rôle de l'hydrogène intervenant dans les propriétés du plasma en rappelant les caractéristiques des plasmas Ar-H2 utilisés pour fondre et purifier le silicium. Les caractéristiques physico-chimiques du silicium purifié montrent que l'hydrogène diffuse dans le matériau et est en mesure de cicatriser les défauts cristallins par formation de liaisons chimiques stables de type Si-H.

Brotto, Lori A; Basson, Rosemary

2014-06-01

At least a third of women across reproductive ages experience low sexual desire and impaired arousal. There is increasing evidence that mindfulness, defined as non-judgmental present moment awareness, may improve women's sexual functioning. The goal of this study was to test the effectiveness of mindfulness-based therapy, either immediately or after a 3-month waiting period, in women seeking treatment for low sexual desire and arousal. Women participated in four 90-min group sessions that included mindfulness meditation, cognitive therapy, and education. A total of 117 women were assigned to either the immediate treatment (n = 68, mean age 40.8 yrs) or delayed treatment (n = 49, mean age 42.2 yrs) group, in which women had two pre-treatment baseline assessments followed by treatment. A total of 95 women completed assessments through to the 6-month follow-up period. Compared to the delayed treatment control group, treatment significantly improved sexual desire, sexual arousal, lubrication, sexual satisfaction, and overall sexual functioning. Sex-related distress significantly decreased in both conditions, regardless of treatment, as did orgasmic difficulties and depressive symptoms. Increases in mindfulness and a reduction in depressive symptoms predicted improvements in sexual desire. Mindfulness-based group therapy significantly improved sexual desire and other indices of sexual response, and should be considered in the treatment of women's sexual dysfunction.

Maintaining Sexual Desire in Long-Term Relationships: A Systematic Review and Conceptual Model.

PubMed

Mark, Kristen P; Lasslo, Julie A

The most universally experienced sexual response is sexual desire. Though research on this topic has increased in recent years, low and high desire are still problematized in clinical settings and the broader culture. However, despite knowledge that sexual desire ebbs and flows both within and between individuals, and that problems with sexual desire are strongly linked to problems with relationships, there is a critical gap in understanding the factors that contribute to maintaining sexual desire in the context of relationships. This article offers a systematic review of the literature to provide researchers, educators, clinicians, and the broader public with an overview and a conceptual model of nonclinical sexual desire in long-term relationships. First, we systematically identified peer-reviewed, English-language articles that focused on the maintenance of sexual desire in the context of nonclinical romantic relationships. Second, we reviewed a total of 64 articles that met inclusion criteria and synthesized them into factors using a socioecological framework categorized as individual, interpersonal, and societal in nature. These findings are used to build a conceptual model of maintaining sexual desire in long-term relationships. Finally, we discuss the limitations of the existing research and suggest clear directions for future research.

Adolescent Narcissism, Aggression, and Prosocial Behavior: The Relevance of Socially Desirable Responding.

PubMed

Barry, Christopher T; Lui, Joyce H L; Anderson, Alexandra C

2017-01-01

An important threat to validity in personality research pertains to an individual's motivation to respond in a socially desirable manner on self-report inventories. This issue was examined in this study in the context of narcissism, aggression, and prosocial behavior in a sample of at-risk adolescents. Participants were 161 adolescents (128 males, 29 females, 4 not reported) ranging in age from 16 to 19 years who were attending a residential program for youth who have dropped out of school. Overall, socially desirable response tendencies were negatively correlated with vulnerable narcissism and self-reported aggression. Moreover, low socially desirable responses strengthened the relation between narcissism and self-reported aggression. Socially desirable responding was not associated with self- or peer-reported prosocial behavior and did not moderate the relation between narcissism and prosocial behavior. These findings indicate that the relation between narcissism and aggression is attenuated by concerns with social desirability. However, further work is needed in broader samples of adolescents to more closely examine whether social desirability concerns actually mitigate aggression among some youth or signify underreporting of one's problem behaviors.

Au Canada, l'amélioration de l'expérience des patients est devenue une priorité des politiques de santé. Le perfectionnement et la normalisation des outils et systèmes pour surveiller les mesures de l'expérience des patients augmentent, tandis que la tendance vers une plus grande reddition de compte sur des améliorations durables et abordables se confirme. Pour de nombreux professionnels de la santé, ce phénomène fait foi d'un intérêt renouvelé pour les besoins et priorités fondamentaux des patients, après des décennies où les changements structurels et technologiques ont dominé les programmes de santé. Pour les leaders en santé canadiens, l'amélioration de l'expérience des patients comporte actuellement de grands défis et de belles possibilités. À cet égard, l'expérience des organisations partenaires du groupe Studer au Canada est à la fois pertinente et instructive. Ces organisations ont adopté un modèle, du nom de Evidence-Based Leadership (EBL, ou leadership fondé sur des données probantes), qui favorise et soutient l'harmonisation de l'ensemble des activités et des comportements, conformément à des objectifs organisationnels précis, y compris des améliorations mesurables de l'expérience des patients. Le présent article expose des études de cas d'organisations qui ont adopté l'EBL. Ces organisations ont réalisé des progrès rapides en matière d'indicateurs de l'expérience des patients, ainsi que dans des secteurs essentiels comme les résultats cliniques, la sécurité et le rendement financier. Les données émergentes sur les facteurs et processus qui sous-tendent ces améliorations sont également abordées. © 2015 Collège canadien des leaders en santé

The literature lacks studies of the male sex drive. Most existing studies have focused on hypoactive sexual desire disorder in coupled heterosexual men, highlighting some of the main related biological, psychological, and social factors. To evaluate the role of selected psychological and social variables affecting male sexual desire such as quality of life, sexual function, distress, satisfaction, psychological symptoms, emotions, alexithymia, couple adjustment, sexism, cognitive schemas activated in a sexual context, sexual dysfunctional beliefs, and different classes of cognitions triggered during sexual activity about failure anticipation, erection concerns, age- and body-related thoughts, erotic fantasies, and negative attitudes toward sexuality. A wide self-administered survey used snowball sampling to reach 298 heterosexual Italian men (age = 32.66 ± 11.52 years) from the general population. 13 questionnaires exploring psychological and social elements involved in sexual response were administrated: International Index of Erectile Function, Short Form 36 for Quality of Life, Beck Depression Inventory-II, Symptom Check List-90-Revised, Toronto Alexithymia Scale, Premature Ejaculation Severity Index, Sexual Distress Scale, Sexual Satisfaction Scale, Dyadic Adjustment Scale, Ambivalent Sexism Inventory, Sexual Modes Questionnaire, Sexual Dysfunctional Belief Questionnaire, and Questionnaire of Cognitive Schema Activation in Sexual Context. Results showed lack of erotic thoughts (β = -0.328), fear (β = -0.259) and desire to have a baby (β = -0.259) as the main predictors of the level of sexual desire in this group. Energy-fatigue, depression, premature ejaculation severity, sexual distress, compatibility, subjective sexual response, and sexual conservatism had a weaker effect on sexual desire. Sexual functioning (13.80%), emotional response (12.70%), dysfunctional sexual beliefs (12.10%), and negative automatic thoughts (12.00%) had more variable

Recent studies investigating the relationship between sexual desire and sexual attraction have found that heterosexual women's reported sexual desire is positively correlated with their reported attraction to both own- and opposite-sex individuals, but that heterosexual men's reported sexual desire is positively correlated with their reported attraction to opposite-sex individuals only. These findings have led to the proposal that sexual desire is a generalized energizer of sexual attraction in heterosexual women (i.e., influences women's attraction to both men and women), but only energizes heterosexual men's sexual attraction to women. Here we show that heterosexual men's scores on the Sexual Desire Inventory-2 were positively correlated with their preferences for exaggerated sex-typical shape cues in opposite-sex, but not own-sex, faces. Together with previous research showing that heterosexual women's reported sexual desire is positively correlated with their preferences for exaggerated sex-typical shape cues in both own- and opposite-sex faces, our findings present novel converging evidence for sex-specific relationships between sexual desire and attractiveness judgments of own- and opposite-sex individuals.

Sur la modélisation des supraconducteurs : le ``modèle de l'état critique'' de Bean, en trois dimensions

NASA Astrophysics Data System (ADS)

Bossavit, A.

1993-03-01

Macroscopic modelling of superconductors demands a substitution of some nonlinear behavior law for Ohm's law. For this, a version of Bean's “critical state” model, derived from the setting of a convex functional of the current density field, valid in dimension 3 without any previous assumption about the direction of currents, is proposed. It is shown how two standard three-dimensional finite element methods (“h-formulation” and “e-formulation”), once fitted with this model, can deal with situations were superconductors are present. La modélisation macroscopique des supraconducteurs suppose le remplacement de la loi d'Ohm par une loi de comportement non linéaire adéquate. On présente à cet effet une version du “modèle de Bean”, ou modèle de l'état critique, basée sur la construction d'une certaine fonctionnelle convexe du champ des densités de courant, qui est valable en dimension 3 sans hypothèses préalables sur la direction des courants. On montre comment adapter deux méthodes standards de calcul de courants de Foucault par élérnents finis en trois dimensions (“en h” et “en e”) à la présence de supraconducteurs, en incorporant ce modèle.

Gender-specificity of solitary and dyadic sexual desire among gynephilic and androphilic women and men.

PubMed

Dawson, Samantha J; Chivers, Meredith L

2014-04-01

Incentive motivation theory proposes that sexual desire emerges from sexual arousal, and is triggered by sexually competent stimuli. Research demonstrates gender and sexual orientation differences in the features that contribute to the competency of sexual stimuli. Men's and gynephilic women's genital arousal tends to be gender-specific with preferred gender eliciting significantly greater genital arousal than nonpreferred gender. In contrast, stimuli depicting preferred and nonpreferred gender elicit similar degrees of genital arousal among androphilic women, termed a gender-nonspecific pattern. Given these differences in the features that elicit a sexual response, and that sexual desire is proposed to emerge from sexual arousal, the question remains as to whether sexual desire would emerge only through exposure to preferred stimuli or whether patterns of responsive desire would parallel those observed for genital arousal. The study aims to examine patterns of dyadic and solitary sexual desire in response to stimuli differing in incentive value. Thirty androphilic women, 21 gynephilic women, 21 gynephilic men, and 16 androphilic men participated in a sexual psychophysiological session. Participants viewed sexual stimuli that varied the gender of the actors and the intensity of sexual activities depicted. Participants reported their degree of desire for sex with a partner (dyadic desire) and desire to masturbate (solitary desire), before and after each film. Men and gynephilic women exhibited gender-specific patterns of sexual desire. Androphilic women's dyadic desire showed significantly less differentiation between genders, and their solitary desire did not differentiate at all. No gender difference was observed for either type of desire. All groups reported greater desire as stimulus intensity increased. Gender-nonspecific sexual response is not limited to the sexual arousal patterns of androphilic women, but extends to include responsive sexual desire. Men and

The impact of female education on fertility desires in Bangladesh.

Matin, K A

1985-01-01

The objective of this study is to determine whether in Bangladesh a wife's educational level significantly affects her desire for more children, or whether Bangladesh has not yet reached the threshold of socioeconomic development where education has any effect on the number of additional children desired. The analysis was carried out in a rural-urban context and also at different stages in the woman's life cycle, as defined by parity at time of interview. 2-3 live births were considered early stage, and 4 or more were defined as later stage. The analysis was carried out on 2791 women selected from the Bangladesh Fertility Survey of 1975-76 who at the time of interview met the criteria of being married, fecund, parity of 2 or more, and having a husband present in the household. The method used to perform the analysis was the Maximum Likelihood estimation method for the truncated dependent variable developed by J. Tobin. The method is a hybrid of probit analysis and classical regression and was chosen because the dependent variable, number of additional children desired, had a clustering of values at the lower limit of O. Separate regressions were run by life cycle stage (parity) and rural-urban background. The effect of variables such as the education of the husband, age, age at first marriage, work status of wife, number of living male children, and infant mortality were held constant in order to find the impact of education on desired fertility. The study found that the number of additional children desired by rural wives was greater than that desired by urban wives at all stages of the life cycle. The mean number of additional children desired by a rural wife at the early stage of the life cycle was .57 and in the later stage .15. For urban women the corresponding values were .29 and .12. The study found that the educational level of both the wife and the husband and the age of the wife at first marriage were not significant. The age of the woman was not

Nuevo León contains a relatively high richness of lizards in the genus Sceloporus. Overlap in the herpetofauna of Nuevo León and states it borders is fairly extensive. Of 130 native species, 102 are considered species of Least Concern in the IUCN red list, four are listed as Vulnerable, five are listed as Near Threatened, and four are listed as Endangered. According to SEMARNAT, 78 species are not of conservation concern, 25 are subject to Special Protection, 27 are Threatened, and none are listed as in Danger of Extinction. Given current threats to the herpetofauna, additional efforts to understand the ecology and status of populations in Nuevo León are needed.

Is love colorblind? Political orientation and interracial romantic desire.

PubMed

Eastwick, Paul W; Richeson, Jennifer A; Son, Deborah; Finkel, Eli J

2009-09-01

The present research examined the association of political orientation with ingroup favoritism in two live romantic contexts. In Study 1, White participants had sequential interactions with both a White and Black confederate and reported their romantic desire for each. In Study 2, both White and Black participants speed-dated multiple potential romantic partners and reported whether they would be interested in meeting each speed-dating partner again. In both studies, White participants' political conservatism positively predicted the strength of the ingroup-favoring bias: White conservatives were less likely than White liberals to desire Black (interracial) relative to White potential romantic partners. In contrast, Black participants' political conservatism negatively predicted the strength of the ingroup-favoring bias: Consistent with system-justification theory, Black conservatives were more likely than Black liberals to desire White (interracial) relative to Black potential romantic partners. Political orientation may be a key factor that influences the initiation of interracial romantic relationships.

A Le Fort I osteotomy is widely used to correct dentofacial deformity because it is a safe and reliable surgical method. Although rare, various complications have been reported in relation to pterygomaxillary separation. Cranial nerve damage is one of the serious complications that can occur after Le Fort I osteotomy. In this report, a 19-year-old man with unilateral cleft lip and palate underwent surgery to correct maxillary hypoplasia, asymmetry and mandibular prognathism. After the Le Fort I maxillary osteotomy, the patient showed multiple cranial nerve damage; an impairment of outward movement of the eye (abducens nerve), decreased vision (optic nerve), and paraesthesia of the frontal and upper cheek area (ophthalmic and maxillary nerve). The damage to the cranial nerve was related to an unexpected sphenoid bone fracture and subsequent trauma in the cavernous sinus during the pterygomaxillary osteotomy.

2015-01-01

Objective: The purposes of this study were (i) to examine the relationship between reported hearing protector use and social desirability bias, and (ii) to compare results of the Marlowe-Crowne social desirability instrument when administered using two different methods (i.e. online and by telephone). Methods: A shortened version of the Marlowe-Crowne social desirability instrument, as well as a self-administered instrument measuring use of hearing protectors, was administered to 497 participants in a study of hearing protector use. The relationship between hearing protector use and social desirability bias was examined using regression analysis. The results of two methods of administration of the Marlowe-Crowne social desirability instrument were compared using t-tests and regression analysis. Results: Reliability (using Cronbach’s alpha) for the shortened seven-item scale for this sample was 0.58. There was no evidence of a relationship between reported hearing protector use and social desirability reporting bias, as measured by the shortened Marlowe-Crowne. The difference in results by method of administration (i.e. online, telephone) was very small. Conclusions: This is the first published study to measure social desirability bias in reporting of hearing protector use among farmers. Findings of this study do not support the presence of social desirability bias in farmers’ reporting of hearing protector use, lending support for the validity of self-report in hearing protector use in this population.

Nutrition chez le brûlé

Perro, G.

2016-01-01

Summary La nutrition est un challenge chez le brûlé, paradigme de l’agressé. Les points importants sont les apports entéraux précoces par sonde gastrique voire post pyloriques, la position proclive > 30°, la surveillance du transit et sa régulation par gastro ou entéro-kinétiques, la surveillance du poids, la quantification des apports avec supplémentation parentérale en cas de retard protéino énergétique. Chez l’enfant, l’adhésion à l’alimentation est difficile, de même que chez le senior, où une évaluation nutritionnelle initiale dépiste souvent une dénutrition préexistante. Les compléments alimentaires seront largement prescrits chez les patients de gravité intermédiaire. Les obèses bénéficieront d’un régime hypocalorique et hyperprotidique. Chez l’insuffisant rénal non dialysé il convient de limiter les apports en potassium. En cas brûlure périnéale, on peut proposer soit une constipation de courte durée, soit la mise en place d’un entéro-collecteur, les indications de colostomie étant devenues rares. Les apports entéraux sont difficiles à gérer en cas de décubitus ventral pour SDRA. Chez le brûlé grave de réanimation, l’accent doit plus être mis sur la qualité des nutriments que sur leur quantité. Les anciennes formules d’estimation calorique conduisaient à une surnutrition difficile à administrer et en général mal tolérée; la quantification mesurée par calorimétrie indirecte ou estimée par la formule de Toronto est bien plus adaptée. Plus récemment, l’instauration d’une immunonutrition (supplémentation en vitamines et oligo-éléments, glutamine, arginine, acide Ω 3 et contrôle raisonné de la glycémie) a été proposée pour réduire le stress oxydatif et l’inflammation provoqués par l’accident.

Malaysia is a Southeast Asian country in which multiple languages are prominently spoken, including English and Mandarin Chinese. As psychological science continues to develop within Malaysia, there is a need for psychometrically sound instruments that measure psychological phenomena in multiple languages. For example, assessment tools for measuring social desirability could be a useful addition in psychological assessments and research studies in a Malaysian context. This study examined the psychometric performance of the English and Mandarin Chinese versions of the Marlowe-Crowne Social Desirability Scale when used in Malaysia. Two hundred and eighty-three students (64% female; 83% Chinese, 9% Indian) from two college campuses completed the Marlowe-Crowne Social Desirability Scale in their language of choice (i.e., English or Mandarin Chinese). Proposed factor structures were compared with confirmatory factor analysis, and multiple indicators-multiple causes models were used to examine measurement invariance across language and sex. Factor analyses supported a two-factor structure (i.e., Attribution and Denial) for the measure. Invariance tests revealed the scale was invariant by sex, indicating that social desirability can be interpreted similarly across sex. The scale was partially invariant by language version, with some non-invariance observed within the Denial factor. Non-invariance may be related to differences in the English and Mandarin Chinese languages, as well as cultural differences. Directions for further research include examining the measurement of social desirability in other contexts where both English and Mandarin Chinese are spoken (i.e., China) and further examining the causes of non-invariance on specific items. © 2016 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

Desired change in couples: gender differences and effects on communication.

Using a sample (N = 453) drawn from a representative sampling frame of couples who are married or living together and have a 3 to 7 year-old child, this study investigates (a) the amount and specific areas of change desired by men and women, (b) the relation between relationship adjustment and desired change; and (c) the ways in which partners negotiate change. On the Areas of Change Questionnaire, women compared with men, wanted greater increases in their partners' emotional and companionate behaviors, instrumental support, and parenting involvement; men wanted greater increases in sex. Using the Actor-Partner Interdependence Model (Kenny, 1996), both men's and women's relationship adjustment predicted desired change (i.e., actor effects), over and above the effects of their partners' adjustment (i.e., partner effects); partner effects were not significant. Each couple was also observed discussing the man's and the woman's top desired change area. Both men and women behaved more positively during the partner-initiated conversations than during their own-initiated conversations. Women, compared with men, were more negative in their own and in their partners' conversations. (PsycINFO Database Record (c) 2009 APA, all rights reserved).

2017-05-01

Adolescent bullying may be a key driver of interest in cosmetic surgery. This study examined the extent of such interest and whether any effect was sex-specific, and examined psychological functioning as a potential mechanism through which bullying involvement may lead to a wish for cosmetic surgery. A two-stage design was used. In the first stage, 2782 adolescents (aged 11 to 16 years) were screened for bullying involvement using self-reports and peer nominations. In the second stage, 752 adolescents who were bullies, victims, bully-victims, or uninvolved in bullying reported their desire for cosmetic surgery. Psychological functioning was constructed as a composite of self-esteem and emotional problems (assessed at stage 1) and body-esteem scores (assessed at stage 2). Adolescents involved in bullying in any role were significantly more interested in cosmetic surgery than uninvolved adolescents. Desire for cosmetic surgery was greatest in adolescents who were bullied (victims and bully-victims) and girls. Desire for cosmetic surgery was highest in girls, but sex did not interact with bullying role. Being victimized by peers resulted in poor psychological functioning, which increased desire for cosmetic surgery. In contrast, desire for cosmetic surgery in bullies was not related to psychological functioning, which was in the normal range. Bullying victimization is related to poor psychological functioning, and both are related to a greater desire for cosmetic surgery in adolescents. Cosmetic surgeons should screen candidates for psychological vulnerability and may want to include a short screening questionnaire for a history of peer victimization.

Fertility decisions and desires in Bangladesh: an econometric investigation.

1976-07-01

2 models are developed to examine fertility behavior in Bangladesh. The 1st model deals with the total number of ever-born children to a couple; the 2nd examines sequential decisions that characterize the desire for an additional child. The "Chicago-Columbia" or "New Home Economics" approach is used, but to the usual economic variables are added sociological and demographic variables; and fertility is examined in relation to the prices of child services consumed as well as a valuation of the mother's time. The data for the study were drawn from a sample of 3088 currently married women respondents to the 1968/69 Impact Survey (an extended KAP survey). The model for completed family size uses 4 endogenous variables: total live births, number of dead children, current income, and female labor force participation; these are examined in terms of 14 exogenous variables, including property ownership, age, literacy, awareness of family planning, rural vs urban, type of family, size of family, and schooling. The model is built on 4 equations with parameters estimated by 2-stage least squares technic and then subjected to multivariate analysis. The model for demand for additional children added 5 exogenous variables including sex of children, desire for children, and perceived need for education of children. This model was examined using standard probit analysis. Interpretation of the 2 models showed that 1) Income was positively related to completed family size but has no effect on desire for additional children; 2) female education, female employment, and cost of fertility control had no effect in either model; 3) Age at marriage had a positive effect on completed family size but none on desire for additional children; 4) Urban women had more live births, but rural women were more likely to want additional children; 5) Sex preference for boys is intense in Bangladesh. The study concludes that: 1) Economic well-being effects fertility; 2) The more adequate couples consider

Normative influence and desired family size among young people in rural Egypt.

Harbour, Catherine

2011-06-01

Research has identified the lack of acceptance of a two-child-family norm as the biggest obstacle to achieving replacement-level fertility in Egypt. This analysis examines norms about desired family size for 1,366 males and 1,367 females aged 15-24 in 2004 in rural Minya governorate. Two-level random-effects multivariate logistic regression models, stratified by sex and grouped by neighborhood, are used to assess normative influence at the household and neighborhood levels, controlling for individual- and household-level covariates. In the final model, young males in neighborhoods where more people desire a small family are 33 percent more likely to desire a small family than are young males in other neighborhoods. Young females in households with one or more adults preferring a small family are 78 percent more likely to desire a small family, and young females in households with one or more young people who prefer a small family are 37 percent more likely to desire a small family themselves, compared with those living with adults or with young people, respectively, who do not prefer a small family. Programs aiming to reduce fertility should be aware of gender differences in the sources of normative influence on desired family size.

To explore personality traits considered to be important in selection of trainees by consultant anaesthetists in a developing country. A questionnaire listing 28 traits was sent to 125 consultant anaesthetists. The raters were asked to mark each trait on a scale of 1 to 10, with one being least desirable and 10 as most desirable. Listing of five most desirable and one least desirable trait was also required. The response rate was 79%. The most desirable trait was identified as reliability by 40%, followed by honesty 17%, functionality under stress 9%, punctuality 7%, and discipline 4%. The least desirable trait was considered as resourcefulness (21%), sense of humour (20%), unassuming mannerism (15%), high self esteem (11%), inquisitive (5%) and expedious (5%). Some traits have been identified as more desirable than others for trainees in our country. We plan to assess these in structured behavioural interviews in our residency programme.

Neural Substrates of Sexual Desire in Individuals with Problematic Hypersexual Behavior

Studies on the characteristics of individuals with hypersexual disorder have been accumulating due to increasing concerns about problematic hypersexual behavior (PHB). Currently, relatively little is known about the underlying behavioral and neural mechanisms of sexual desire. Our study aimed to investigate the neural correlates of sexual desire with event-related functional magnetic resonance imaging (fMRI). Twenty-three individuals with PHB and 22 age-matched healthy controls were scanned while they passively viewed sexual and nonsexual stimuli. The subjects' levels of sexual desire were assessed in response to each sexual stimulus. Relative to controls, individuals with PHB experienced more frequent and enhanced sexual desire during exposure to sexual stimuli. Greater activation was observed in the caudate nucleus, inferior parietal lobe, dorsal anterior cingulate gyrus, thalamus, and dorsolateral prefrontal cortex in the PHB group than in the control group. In addition, the hemodynamic patterns in the activated areas differed between the groups. Consistent with the findings of brain imaging studies of substance and behavior addiction, individuals with the behavioral characteristics of PHB and enhanced desire exhibited altered activation in the prefrontal cortex and subcortical regions. In conclusion, our results will help to characterize the behaviors and associated neural mechanisms of individuals with PHB. PMID:26648855

The Scope and Standards of Professional School Nursing Practice states that school nurses should evaluate the quality and effectiveness of their practice. School nurses have not yet identified and adopted outcomes by which this effectiveness can be measured. This study used focus groups during a national meeting of school nurse leaders to identify the desired outcomes that could be used to measure the efficacy of school nursing practice. Ten desired outcome themes were identified with numerous specific indicators as possible ways to measure the desired outcome in each theme. The student-, school-, and nurse-focused outcome themes were as follows: (a) increased student seat time, (b) receipt of first aid and acute care measures, (c) receipt of competent health-related interventions or skills, (d) meeting of the comprehensive needs of children with chronic conditions, (e) enhanced school health via wellness promotion and disease prevention measures, (f) referrals, (g) safe environment, (h) enhanced school health via community outreach, (i) cost-effective school nurse services, and (j) student, parent, and staff satisfaction. The school nurse participants were supportive of having potential outcomes identified and unanimously endorsed the findings at the conclusion of the study. They have provided a comprehensive framework from which evaluation tools can be developed to measure the efficacy of school nursing.

Le(x) glycan mediates homotypic adhesion of embryonal cells independently from E-cadherin: a preliminary note.

Le(x) glycan and E-cadherin (Ecad) are co-expressed at embryonal stem (ES) cells and embryonal carcinoma (EC) cells. While the structure and function of Ecad mediating homotypic adhesion of these cells have been well established, evidence that Le(x) glycan also mediates such adhesion is weak, despite the fact that Le(x) oligosaccharide inhibits the compaction process. To provide stronger evidence, we knocked out Ecad gene in EC and ES cells to establish F9 Ecad (-/-) and D3M Ecad (-/-) cells, which highly express Le(x) glycan but do not express Ecad at all. Both F9 Ecad (-/-) and D3M Ecad (-/-) cells displayed strong autoaggregation in the presence of Ca(2+), while PYS-2 cells, which express trace amount of Ecad and undetectable level of Le(x) glycan, did not display autoaggregation. In addition, F9 Ecad (-/-) and D3M Ecad (-/-) cells displayed strong adhesion to plates coated with Le(x) glycosphingolipid (III(3)FucnLc4Cer), in dose-dependent manner, in the presence of Ca(2+). Thus, ES or EC cells display autoaggregation and strong adhesion to Le(x)-coated plates in the absence of Ecad, further supporting the notion of Le(x) self-recognition (i.e., Le(x)-to-Le(x) interaction) in cell adhesion.

Conductivite dans le modele de Hubbard bi-dimensionnel a faible couplage

NASA Astrophysics Data System (ADS)

Bergeron, Dominic

Le modele de Hubbard bi-dimensionnel (2D) est souvent considere comme le modele minimal pour les supraconducteurs a haute temperature critique a base d'oxyde de cuivre (SCHT). Sur un reseau carre, ce modele possede les phases qui sont communes a tous les SCHT, la phase antiferromagnetique, la phase supraconductrice et la phase dite du pseudogap. Il n'a pas de solution exacte, toutefois, plusieurs methodes approximatives permettent d'etudier ses proprietes de facon numerique. Les proprietes optiques et de transport sont bien connues dans les SCHT et sont donc de bonne candidates pour valider un modele theorique et aider a comprendre mieux la physique de ces materiaux. La presente these porte sur le calcul de ces proprietes pour le modele de Hubbard 2D a couplage faible ou intermediaire. La methode de calcul utilisee est l'approche auto-coherente a deux particules (ACDP), qui est non-perturbative et inclue l'effet des fluctuations de spin et de charge a toutes les longueurs d'onde. La derivation complete de l'expression de la conductivite dans l'approche ACDP est presentee. Cette expression contient ce qu'on appelle les corrections de vertex, qui tiennent compte des correlations entre quasi-particules.

Problematic internet pornography use: The role of craving, desire thinking, and metacognition.

PubMed

Allen, Andrew; Kannis-Dymand, Lee; Katsikitis, Mary

2017-07-01

Defined as sexually explicit material that elicits erotic thoughts, feelings, and behaviours, internet pornography is a prevalent form of media that may facilitate problematic use and craving for engagement. Research suggests that superordinate cognitions and information processing, such as desire thinking and metacognition, are central to the activation and escalation of craving in addictive behaviours. The current study aimed to contribute to the literature by testing the proposed metacognitive model of desire thinking and craving in a sample of problematic pornography users, while revising the model by incorporating negative affect. From a theoretical perspective, environmental cues trigger positive metacognitions about desire thinking that directly influence desire thinking, resulting in the escalation of craving, negative metacognitions, and negative affect. Participants were recruited via an online survey and screened for problematic internet pornography use. Path analyses were used to investigate relationships among the aforementioned constructs in a final sample of 191 participants. Consistent with previous research, results of this study validated the existence of metacognitive processes in the activation of desire thinking and escalation of craving, while indicating that desire thinking has the potential to influence negative affect. Additionally, results supported the role of significant indirect relationships between constructs within the revised model of metacognition, desire thinking, and psychopathology. Collectively, the findings demonstrate the clinical value of a metacognitive conceptualisation of problematic pornography use. Exploring the metacognitive mechanisms that underpin problematic internet pornography use may give rise to the development of new treatment and relapse prevention strategies.

2010-01-01

Objective Recent studies have suggested that the brain circuitry mediating cue induced desire for video games is similar to that elicited by cues related to drugs and alcohol. We hypothesized that desire for internet video games during cue presentation would activate similar brain regions to those which have been linked with craving for drugs or pathological gambling. Methods This study involved the acquisition of diagnostic MRI and fMRI data from 19 healthy male adults (ages 18–23 years) following training and a standardized 10-day period of game play with a specified novel internet video game, “War Rock” (K-network®). Using segments of videotape consisting of five contiguous 90-second segments of alternating resting, matched control and video game-related scenes, desire to play the game was assessed using a seven point visual analogue scale before and after presentation of the videotape. Results In responding to internet video game stimuli, compared to neutral control stimuli, significantly greater activity was identified in left inferior frontal gyrus, left parahippocampal gyrus, right and left parietal lobe, right and left thalamus, and right cerebellum (FDR <0.05, p<0.009243). Self-reported desire was positively correlated with the beta values of left inferior frontal gyrus, left parahippocampal gyrus, and right and left thalamus. Compared to the general players, members who played more internet video game (MIGP) cohort showed significantly greater activity in right medial frontal lobe, right and left frontal pre-central gyrus, right parietal post-central gyrus, right parahippocampal gyrus, and left parietal precuneus gyrus. Controlling for total game time, reported desire for the internet video game in the MIGP cohort was positively correlated with activation in right medial frontal lobe and right parahippocampal gyrus. Discussion The present findings suggest that cue-induced activation to internet video game stimuli may be similar to that observed

Is High Sexual Desire a Risk for Women's Relationship and Sexual Well-Being?

PubMed

Štulhofer, Aleksandar; Bergeron, Sophie; Jurin, Tanja

2016-09-01

Historically, women's sexual desire has been deemed socially problematic. The growing popularity of the concept of hypersexuality-which lists high sexual desire among its core components-poses a risk of re-pathologizing female sexual desire. Data from a 2014 online survey of 2,599 Croatian women aged 18-60 years was used to examine whether high sexual desire is detrimental to women's relationship and sexual well-being. Based on the highest scores on an indicator of sexual desire, 178 women were classified in the high sexual desire (HSD) group; women who scored higher than one standard deviation above the Hypersexual Disorder Screening Inventory mean were categorized in the hypersexuality (HYP) group (n = 239). Fifty-seven women met the classification criteria for both groups (HYP&HSD). Compared to other groups, the HSD was the most sexually active group. Compared to controls, the HYP and HYP&HSD groups-but not the HSD group-reported significantly more negative consequences associated with their sexuality. Compared to the HYP group, women with HSD reported better sexual function, higher sexual satisfaction, and lower odds of negative behavioral consequences. The findings suggest that, at least among women, hypersexuality should not be conflated with high sexual desire and frequent sexual activity.

The attitudes of mental health professionals towards patients' desire for children.

2014-03-02

When a patient with a serious mental illness expresses a desire for children, mental health professionals are faced with an ethical dilemma. To date, little research has been conducted into their strategies for dealing with these issues. Seven focus groups with a total of 49 participants from all professional groups active in mental health (nurses, psychologists, social workers and psychiatrists) were conducted in a 330-bed psychiatric hospital. Group discussions were transcribed verbatim and analysed by the documentary method described by Bohnsack. Mental health professionals did not feel that their patients' desire for children was as important in daily practice as were parenting issues. When discussing the desire for children on the part of patients, the following themes emerged: "the patient's own decision", "neutrality", "the patient's well-being", "issues affecting the children of mentally ill parents" and "appropriate parenthood". In order to cope with what they perceived as conflicting norms, mental health professionals developed the following (discursive) strategies: "subordination of child welfare", "de-professionalisation", "giving rational advice" and "resignation". The theme of "reproductive autonomy" dominated mental health professionals' discourse on the desire for children among psychiatric patients. "Reproductive autonomy" stood in conflict with another important theme (patient's children). Treating reproductive issues as taboo is the result of the gap between MHPs' perceptions of (conflicting) norms when dealing with a patient's desire for children and the limited opportunities to cope with them appropriately.In order to support both patients with a desire for children and mental health professionals who are charged with providing counselling for such patients, there is a need to encourage ethical reflection and to focus on clinical recommendations in this important area.

Sexual desire, erectile dysfunction and the biomedicalization of sex in older heterosexual men.

PubMed

Gledhill, Susan; Schweitzer, Robert D

2014-04-01

To examine sexual desire in older age and the use of pharmaceuticals for sexual enhancement in the context of erectile dysfunction. The ability of the older person to fulfil sexual desire has not been well supported in Western society. The paper draws on themes that emerged during a phenomenological study of sexual desire in older age. Narratives were collected between 2008-2010 from in-depth interviews with six men and two women aged 65-84 years who were part of a larger Australian study of sexual desire in older age. Emergent themes reveal that for some older people, the biomedicalization of sex can be a disappointing experience. The findings illuminate the need for nurses who are at the front line of health care, health policy makers and educators, to consider sexual desire experienced in older age in the context of sexual health and healthy ageing. This study will contribute to a growing body of knowledge about sexual desire in older age. © 2013 John Wiley & Sons Ltd.

Fulfilment of intention and desire in children's judgements of emotion for sociomoral events.

PubMed

Shiverick, Sean M; Moore, Colleen F

2013-11-01

This study investigated whether children appreciate that enacting an intention can emotionally affect an agent separately from whether the agent's desire is fulfilled. Children ages 5-11 years and adults heard several vignettes about an agent who intended to take another child's toy in which the agent's intention was either enacted or blocked and desire was fulfilled or unfulfilled. The effect of intention on judgements of the agent's emotion varied according to desire fulfilment and age. Overall, participants judged that an agent who acted intentionally to fulfil a desire felt happier than an agent whose intention was blocked. When the agent's desire was unfulfilled, the effect of enacting an intention varied by age. Five- to 6-year-olds judged that acting intentionally could decrease the negative emotion associated with an unfulfilled desire. The findings show relatively early appreciation of intentionality in children's judgements of emotion. Happy victimizer attributions decreased between 5 and 8 years, but attributions of positive emotion to transgressors did not vary by intentionality. The relationships between intentionality, agency, and emotion are discussed. © 2013 The British Psychological Society.

Conning the conmen: Intelligence and female desire in Dedh Ishqiya.

PubMed

Singh, Shailendra Kumar

2018-01-02

This article investigates the ostensibly paradoxical relationship that exists between the theme of excessive love, as suggested by the title of Abhishek Chaubey's film Dedh Ishqiya (2014), and the actual representation of it in the movie, which is not only restrained and disproportionate, but is also looked at with suspicion and contempt. It examines the logic of this seeming contradiction through the other two related themes that Chaubey's chef-d'œuvre foregrounds, namely that of intelligence and female desire. The quest for financial autonomy that the female protagonists of the movie are involved in-a necessary pre-condition for leading independent lives-is so inextricably intertwined with manipulation, dexterity, and subterfuge, that any overt expression of homoerotic female desire can only jeopardize their existing possibilities of self-aggrandizement. The heteronormative arrangements of Begum Para's palace thus constitute the elaborate mise en scène, behind which female desire is enacted through a politics of intelligence, resourcefulness, discretion, and anonymity. Through this strategic negotiation, which is also a tactical necessity, the female protagonists are not only able to con the con men in the movie, but also imagine alternative subject positions that recognize the need for both pragmatism and expediency as well as deconstructing heteropatriarchal economies of desire.

Sexual desire, not hypersexuality, is related to neurophysiological responses elicited by sexual images

PubMed Central

Steele, Vaughn R.; Staley, Cameron; Fong, Timothy; Prause, Nicole

2013-01-01

Background Modulation of sexual desires is, in some cases, necessary to avoid inappropriate or illegal sexual behavior (downregulation of sexual desire) or to engage with a romantic partner (upregulation of sexual desire). Some have suggested that those who have difficulty downregulating their sexual desires be diagnosed as having a sexual ‘addiction’. This diagnosis is thought to be associated with sexual urges that feel out of control, high-frequency sexual behavior, consequences due to those behaviors, and poor ability to reduce those behaviors. However, such symptoms also may be better understood as a non-pathological variation of high sexual desire. Hypersexuals are thought to be relatively sexual reward sensitized, but also to have high exposure to visual sexual stimuli. Thus, the direction of neural responsivity to sexual stimuli expected was unclear. If these individuals exhibit habituation, their P300 amplitude to sexual stimuli should be diminished; if they merely have high sexual desire, their P300 amplitude to sexual stimuli should be increased. Neural responsivity to sexual stimuli in a sample of hypersexuals could differentiate these two competing explanations of symptoms. Methods Fifty-two (13 female) individuals who self-identified as having problems regulating their viewing of visual sexual stimuli viewed emotional (pleasant sexual, pleasant-non-sexual, neutral, and unpleasant) photographs while electroencephalography was collected. Results Larger P300 amplitude differences to pleasant sexual stimuli, relative to neutral stimuli, was negatively related to measures of sexual desire, but not related to measures of hypersexuality. Conclusion Implications for understanding hypersexuality as high desire, rather than disordered, are discussed. PMID:24693355

Desiring foods: Cultivating non-attachment to nourishment in Buddhist Sri Lanka.

PubMed

Van Daele, Wim

2016-10-01

Food and desire are intimately entangled whereby food becomes a core tool to manage desire in fashioning oneself as a morally virtuous person. This paper looks at the ways in which Buddhist texts conceptualize human interactions with food and formulate prescriptions on how to handle food as a means of developing an attitude of non-attachment that aids in achieving nirvana-the extinguishing of desire to get released from the cycle of death and rebirth. The particular texts-the Agañña Sutta, the Āhāra Patikūlasaññā, and the Vinaya Pitaka- discussed here exhibit an attitude of deep ambiguity towards food in its capacity to incite desire. On the one hand nutrition is required to maintain life, but on the other, food can potentially be the cause of a degenerate state of mankind and a source of moral degradation. Hence, the Buddhist development of a dispassionate attitude towards food seeks to enable both nourishment and the pursuit of the extinction of the flame of desire in nirvana. Even though the texts formulate practical prescriptions for monks on how to relate to food to aid them in their pursuit, they also serve as moral standards for lay Sinhalese Buddhists who seek to model their everyday behaviour accordingly.

LeChâtelier's Principle in the Sciences

NASA Astrophysics Data System (ADS)

Thomsen, Volker B. E.

2000-02-01

LeChâtelier's principle of chemical equilibrium is actually a very general statement about systems in equilibrium and their behavior when subjected to external force or stress. Although one almost never finds mention of his name or law in other sciences, analogous principles and concepts do exist. In this note we examine some of the similar forms taken by this chemical principle in the fields of physics, geology, biology, and economics. Lenz's law in physics is an example of electromagnetic equilibrium and the geological principle of isostatic uplift concerns mechanical equilibrium. Both are strictly consequences of conservation of energy. LeChâtelier's principle deals with thermodynamic equilibrium and involves both the first and second laws of thermodynamics. The concept of homeostasis in biology and the economic law of supply and demand are both equilibrium-like principles, but involve systems in the steady state. However, all these principles involve the stability of the system under consideration and the analogies presented may be useful in the teaching of LeChâtelier's principle.

2013-06-01

We conducted a questionnaire survey among Japanese female students to explore the influence of a desire for thinness and dietary behaviors on the development of eating disorders. Self-reported measures of socio-demographic characteristics, body weight perception, height and weight, and dietary and exercise behavior were completed by 631 female university students at 6 universities in Kyoto, Japan. Many students had a desire for thinness (underweight students, 51.7 %; normal-weight students, 88.8 %), whereas ideal weight and body mass index were lower in the students with a desire for thinness than the students without a desire for thinness, and were also lower in the underweight students than the normal-weight students. The eating attitude test (EAT-26) scores of underweight students with a desire for thinness were higher than those of the normal-weight students with a desire for thinness. As a result of a logistic regression analysis, underweight, desire for thinness, and experience with weight control were positively associated with eating problems. Further, the association of eating problems increased along with the increase in the number of factors (underweight, desire for thinness, and experience with weight control). These results indicate that underweight females have strong associations with eating problems.

Hypoactive sexual desire disorder: inventing a disease to sell low libido.

Condition branding is a marketing technique in which companies develop conditions concurrently with developing drugs; examples include gastro-oesophageal reflux disease, premenstrual dysphoric disorder, social anxiety disorder, erectile dysfunction and hypoactive sexual desire disorder. Although it is illegal for pharmaceutical companies to market drugs prior to regulatory approval, there are no restrictions on marketing diseases, and industry seeks to establish a disease state in the minds of clinicians years before an expected drug launch. Continuing medical education (CME) courses are an important part of promotion prior to drug approval and have become a key marketing tool for increasing clinician receptivity to new products. We systematically identified 14 free, internet-based, industry-funded, accredited CME modules on hypoactive sexual desire disorder in women which came out before a new drug, flibanserin, was being considered for regulatory approval in the USA. Common themes in these modules included the following: (1) Hypoactive sexual desire disorder is common, underdiagnosed and can have a profound effect on quality of life. (2) Women may not be aware that they are sick or distressed. (3) Simple questionnaires can assist clinicians in diagnosing the disorder. (4) It is problematic that there are medicines available to treat sexual problems for men but not women. In fact, there is no scientifically established norm for sexual activity, feelings or desire, and there is no evidence that hypoactive sexual desire disorder is a medical condition. Hypoactive sexual desire disorder is a typical example of a condition that was sponsored by industry to prepare the market for a specific treatment. Published by the BMJ Publishing Group Limited.

Nouvelles approches en theorie du champ moyen dynamique: le cas du pouvoir thermoelectrique et celui de l'effet orbital d'un champ magnetique

NASA Astrophysics Data System (ADS)

Arsenault, Louis-Francois

, cette approche donne une bonne representation de S lorsque le systeme devient coherent. Les calculs montrent aussi que la formule Kelvin est precise lorsque la fonction spectrale des electrons devient incoherente, soit a plus haute temperature. Dans la limite Kelvin, S est essentiellement l'entropie par particule, tel que propose il y a longtemps. Nos resultats demontrent ainsi que la vision purement entropique de S est la bonne dans le regime incoherent, alors que dans le regime coherent, l'approche a frequence infinie est meilleure. Nous avons utilise une methode a la fine pointe, soit le Monte-Carlo quantique en temps continu pour resoudre la DMFT. Pour permettre une exploration rapide du diagramme de phase, nous avons du developper une nouvelle version de la methode des perturbations iterees pour qu'elle soit applicable aussi a forte interaction au-dela de la valeur critique de la transition de Mott. Un autre sujet a aussi ete aborde. L'effet orbital du champ magnetique dans les systemes electroniques fortement correles est une question tres importante et peu developpee. Cela est d'autant plus essentiel depuis la decouverte des oscillations quantiques dans les supraconducteurs a haute temperature (haut- Tc). Par desir de developper une methode la moins biaisee possible, nous avons derive la DMFT lorsqu'un champ se couplant a l'operateur energie cinetique par la substitution de Peierls est present. Ce type d'approche est necessaire pour comprendre entre autres l'effet de la physique de Mott sur des phenomenes tels que les oscillations quantiques. Nous avons obtenu un resultat tres important en demontrant rigoureusement que la relation d'auto-coherence de la DMFT et le systeme intermediaire d'impurete quantique restent les memes. L'effet du champ peut etre contenu dans la fonction de Green locale, ce qui constitue la grande difference avec le cas habituel. Ceci permet de continuer a utiliser les solutionneurs d'impuretes standards, qui sont de plus en plus puissants

Suicide, hopelessness, and social desirability: a test of an interactive model.

Holden, R R; Mendonca, J D; Serin, R C

1989-08-01

We examined the relationships among suicidal indices, hopelessness, and social desirability. Both hopelessness and a measure of social desirability that reflected a sense of general capability were significant indicators of suicidal manifestations. In particular, hierarchical multiple regression procedures demonstrated that hopelessness and social desirability interacted in the prediction of suicide variables. Results generalized across various clinical diagnostic subgroups of psychiatric patients and a sample of prisoners and across different clinically evaluated and self-reported indices of suicidal behavior. Findings are interpreted to mean that a sense of general capability buffers the link of hopelessness to suicidal behavior. Implications for understanding the cognitions associated with suicide and for improving prediction of persons at risk are discussed.

Transgenic studies reveal the positive role of LeEIL-1 in regulating shikonin biosynthesis in Lithospermum erythrorhizon hairy roots.

The phytohormone ethylene (ET) is a key signaling molecule for inducing the biosynthesis of shikonin and its derivatives, which are secondary metabolites in Lithospermum erythrorhizon. Although ETHYLENE INSENSITIVE3 (EIN3)/EIN3-like proteins (EILs) are crucial transcription factors in ET signal transduction pathway, the possible function of EIN3/EIL1 in shikonin biosynthesis remains unknown. In this study, by targeting LeEIL-1 (L. erythrorhizon EIN3-like protein gene 1) at the expression level, we revealed the positive regulatory effect of LeEIL-1 on shikonin formation. The mRNA level of LeEIL-1 was significantly up-regulated and down-regulated in the LeEIL-1-overexpressing hairy root lines and LeEIL-1-RNAi hairy root lines, respectively. Specifically, LeEIL-1 overexpression resulted in increased transcript levels of the downstream gene of ET signal transduction pathway (LeERF-1) and a subset of genes for shikonin formation, excretion and/or transportation (LePAL, LeC4H-2, Le4CL-1, HMGR, LePGT-1, LeDI-2, and LePS-2), which was consistent with the enhanced shikonin contents in the LeEIL-1-overexpressing hairy root lines. Conversely, LeEIL-1-RNAi dramatically repressed the expression of the above genes and significantly reduced shikonin production. The results revealed that LeEIL-1 is a positive regulator of the biosynthesis of shikonin and its derivatives in L. erythrorhizon hairy roots. Our findings gave new insights into the molecular regulatory mechanism of ET in shikonin biosynthesis. LeEIL-1 could be a crucial target gene for the genetic engineering of shikonin biosynthesis.

Differences in sexual desire between individuals of East Asian and European descent are well-documented, with East Asian individuals reporting lower sexual desire. The mechanisms that underlie this disparity have received little empirical attention. Recent research has found that sex guilt, "a generalized expectancy for self-mediated punishment for violating or for anticipating violating standards of proper sexual conduct" (Mosher & Cross, 1971 , p. 27), mediates the relationship between culture and sexual desire in East Asian and Euro-Canadian women. The goal of this study was to explore this role of sex guilt in men. Male Euro-Canadian (n = 38) and East Asian (n = 45) university students completed online questionnaires. The East Asian men reported significantly lower sexual desire and significantly higher sex guilt. Sex guilt was a significant mediator of the relationship between ethnicity and sexual desire, as well as a significant mediator between mainstream acculturation and sexual desire. Among the East Asian men, mainstream acculturation was significantly and negatively correlated with sex guilt such that increasing mainstream acculturation was associated with less sex guilt. The diagnostic and clinical implications of the findings are discussed.

Alexithymia is a personality construct comprising difficulty in identifying and describing emotions and externally oriented thinking. Its role in heavy and problematic alcohol consumption is well documented, together with its relationship with social stress. However, little research has examined whether social stress has any effect on desire for alcohol among alexithymic individuals. In this experimental study, we explored the relationship between alexithymia and desire for alcohol in response to an experimental social stressor. One hundred and thirty eight social drinkers completed the Toronto Alexithymia Scale, self-report measures of alcohol consumption and a stress-inducing task. Desire for alcohol was measured at three time points: baseline, stressor and recovery. Correlation analysis demonstrated that alexithymia was associated with significantly higher rates of alcohol consumption and higher levels of desire for alcohol. Mixed measures ANOVA demonstrated a significant main effect of alexithymia and a significant group by time effect of alexithymia on desire for alcohol. Conclusions/Importance: The findings demonstrate increased desire for alcohol before, during and after a social stressor among alexithymic participants. These findings offer an insight into the relationship between alexithymia, social stress and alcohol consumption.

Le modele de Hubbard bidimensionnel a faible couplage: Thermodynamique et phenomenes critiques

Roy, Sebastien

Une etude systematique du modele de Hubbard en deux dimensions a faible couplage a l'aide de la theorie Auto-Coherente a Deux Particules (ACDP) dans le diagramme temperature-dopage-interaction-sauts permet de mettre en evidence l'influence des fluctuations magnetiques sur les proprietes thermodynamiques du systeme electronique sur reseau. Le regime classique renormalise a temperature finie pres du dopage nul est marque par la grandeur de la longueur de correlation de spin comparee a la longueur thermique de de Broglie et est caracterisee par un accroissement drastique de la longueur de correlation de spin. Cette croissance exponentielle a dopage nul marque la presence d'un pic de chaleur specifique en fonction de la temperature a basse temperature. Une temperature de crossover est alors associee a la temperature a laquelle la longueur de correlation de spin est egale a la longueur thermique de de Broglie. C'est a cette temperature caracteristique, ou est observee l'ouverture du pseudogap dans le poids spectral, que se situe le maximum du pic de chaleur specifique. La presence de ce pic a des consequences sur l'evolution du potentiel chimique avec le dopage lorsque l'uniformite thermodynamique est respectee. Les contraintes imposees par les lois de la thermodynamique font en sorte que l'evolution du potentiel chimique avec le dopage est non triviale. On demontre entre autres que le potentiel chimique est proportionnel a la double occupation qui est reliee au moment local. Par ailleurs, une derivation de la fonction de mise a l'echelle de la susceptibilite de spin a frequence nulle au voisinage d'un point critique marque sans equivoque la presence d'un point critique quantique en dopage pour une valeur donnee de l'interaction. Ce point critique, associe a une transition de phase magnetique en fonction du dopage a temperature nulle, induit un comportement non trivial sur les proprietes physiques du systeme a temperature finie. L'approche quantitative ACDP permet de

Social desirability response tendencies in psychiatric inpatient children.

PubMed

Mabe, P A; Treiber, F A

1989-03-01

This study examined the substantive features of children's social desirability (SD) tendencies that could influence the nature and severity of psychopathology. Examinations of substantive features of SD responding in an inpatient child psychiatry unit (N = 76) suggested that higher scores on the Children's Social Desirability questionnaire were associated strongly with (1) lower mental age; (2) higher scores on self-reported social competence; (3) lower scores on self-reported anger; and (4) lower scores on parent-reported externalization behavioral disturbance. Results were interpreted as suggesting that SD responding for child inpatients may reflect a mixed picture of negative features of cognitive and social immaturity that could affect adversely their ability to judge their own and others' social behavior and of positive features of less external behavioral disturbance and more prosocial attitudes and behaviors.

To explore, for the first time, the impact of job insecurity on sexual desire. Cross-sectional analysis of a nationally representative sample of 7247 individuals aged 20-64 years working as full or part-time employees in Switzerland. The logistic regression analysis showed that workers aged 20-49 years perceiving high levels of job insecurity are exposed to a significantly higher risk of decrease of sexual desire compared to the reference group. The risk is 53% higher among men (OR 1.53; 95% CI 1.16-2.01) and 47% for woman (OR 1.47; 1.13-1.91). No increased risk was found for employees aged 50-64 years old. An increasing fear of job loss is associated with a deterioration in sexual desire. These first preliminary findings should promote further epidemiological and clinical prospective studies on the impact of job insecurity on intimate relationships and sexual dysfunction.

Limb amputation and other disability desires as a medical condition.

Some people have a profound dissatisfaction with what is considered an able-bodied state by most others. These individuals desire to be disabled, by conventional standards. In this Review, we integrate research findings about the desire for a major limb amputation or paralysis (xenomelia). Neuropsychological and neuroimaging explorations of xenomelia show functional and structural abnormalities in predominantly right hemisphere cortical circuits of higher-order bodily representation, including affective and sexual aspects of corporeal awareness. These neural underpinnings of xenomelia do not necessarily imply a neurological cause, and a full understanding of the condition requires consideration of the interface between neural and social contributions to the bodily self and the concept of disability. Irrespective of cause, disability desires are accompanied by a disabling bodily dysphoria, in many respects similar to gender dysphoria, and we suggest that they should be considered a mental disorder.

This study was undertaken to determine the prevalence of LE cells in synovial fluid and their importance for the diagnosis of rheumatic disease. Synovial fluid was obtained from 631 patients: 31 with systemic lupus erythematosus (SLE), 337 with rheumatoid arthritis (RA), 4 with Still's disease, 9 with systemic scleroderma (SS), 27 with the overlap syndrome (RA/SLE), 132 with ankylosing spondylitis (AS), 57 with Reiter's syndrome, and 34 with psoriatic arthritis (PA). The fluid was centrifuged, precipitate smears were done and were May-Grünwald-Giemsa stained for cytologic assessment. The supernatant was collected for antinuclear antibody (ANA) testing. Physicochemical and serologic properties of the synovial fluid were routinely determined. All synovial fluids demonstrated signs of inflammation. The presence of LE cells was ascertained in five patients with SLE and nine patients with the overlap syndrome. In these cases, LE cells were accompanied by ANA. In addition, hematoxylin bodies were revealed in SLE patients. LE cells were observed in 2.6% of patients with RA but were not accompanied by ANA. Patients with SS, Still's disease, AS, Reiter's syndrome, and PA tested negative for LE cells. It appears from these results that LE cells are rarely present in the synovial fluid of patients with rheumatic diseases. In contrast, they occur in more than 40% of patients with the overlap syndrome and may thus be regarded as important for the diagnosis of this condition.

Self-report of dietary intake could be biased by social thus affecting risk estimates in epidemiological studies. The objective of study was to assess the effect of social desirability on dietary intake from a food frequency questionnaire (FFQ). A convenience sample of 483 Portuguese university students was recruited. Subjects were invited to complete a two-part self-administered questionnaire: the first part included the Marlowe-Crowne Social Desirability Scale (M-CSDS), a physical activity questionnaire and self-reported height and weight; the second part, included a semi-quantitative FFQ validated for Portuguese adults, that should be returned after fulfillment. All subjects completed the first part of the questionnaire and 40.4% returned the FFQ fairly completed. In multiple regression analysis, after adjustment for energy and confounders, social desirability produced a significant positive effect in the estimates of dietary fibre, vitamin C, vitamin E, magnesium and potassium, in both genders. In multiple regression, after adjustment for energy and confounders, social desirability had a significant positive effect in the estimates of vegetable consumption, for both genders, and a negative effect in white bread and beer, for women. Social desirability affected nutritional and food intake estimated from a food frequency questionnaire.

2005-06-01

The Canadian history of our profession is not well known and our identity is thought to suffer as a result. Helen Primrose LeVesconte (7896-1982) is one pioneer in our development whose story has not been told. Our purpose is to explore LeVesconte's life and work in order to expand knowledge of our roots and thereby strengthen our identity. Using interpretive biography methods we draw on LeVesconte's own writings, articles written about her, and archival documents to describe turning point moments in her life and to display meaningful patterns in her work. LeVesconte's work as a clinician and her role and reputation as an educator, show her to have been a strong and visionary leader. Her views on the client's role, the importance of the therapist-client relationship, prevention, community-based programs, and vocational rehabilitation are of particular interest. Because LeVesconte educated over 1,850 students while director of the occupational therapy program at the University of Toronto, her influence has been felt throughout the country. Her perspective is compared to current practice; and questions are raised as to aspects of her legacy and philosophy that might now be reconsidered.

Assessing food appeal and desire to eat: the effects of portion size & energy density

PubMed Central

2011-01-01

Background Visual presentation of food provides considerable information such as its potential for palatability and availability, both of which can impact eating behavior. Methods We investigated the subjective ratings for food appeal and desire to eat when exposed to food pictures in a fed sample (n = 129) using the computer paradigm ImageRate. Food appeal and desire to eat were analyzed for the effects of food group, portion size and energy density of the foods presented as well as by participant characteristics. Results Food appeal ratings were significantly higher than those for desire to eat (57.9 ± 11.6 v. 44.7 ± 18.0; p < 0.05). Body mass index was positively correlated to desire to eat (r = 0.20; p < 0.05), but not food appeal. Food category analyses revealed that fruit was the highest rated food category for both appeal and desire, followed by discretionary foods. Additionally, overweight individuals reported higher ratings of desire to eat large portions of food compared to smaller portions (p < 0.001), although these effects were relatively small. Energy density of the foods was inversely correlated with ratings for both appeal and desire (r's = - 0.27; p's < 0.01). Conclusions Results support the hypothesis that individuals differentiate between food appeal and desire to eat foods when assessing these ratings using the same type of metric. Additionally, relations among food appeal and desire to eat ratings and body mass show overweight individuals could be more responsive to visual foods cues in a manner that contributes to obesity.

Résumé Objectif Offrir aux médecins de famille un résumé des recommandations fondées sur les données probantes pour guider les soins aux survivantes traitées pour le cancer du sein. Qualité des données Une recherche documentaire a été effectuée dans MEDLINE entre 2000 et 2016 à l’aide des mots-clés anglais suivants : breast cancer, survivorship, follow-up care, aftercare, guidelines et survivorship care plans, en se concentrant sur la revue des lignes directrices publiées récemment par les organismes nationaux de cancérologie. Les données étaient de niveaux I à III. Message principal Les soins aux survivantes comportent 4 facettes : surveillance et dépistage, prise en charge des effets à long terme, promotion de la santé et coordination des soins. La surveillance des récidives ne se traduit que par une mammographie annuelle, et le dépistage d’autres cancers doit suivre les lignes directrices basées sur la population. La prise en charge des effets à long terme du cancer et de son traitement aborde des problèmes courants tels la douleur, la fatigue, le lymphœdème, la détresse et les effets indésirables des médicaments, de même que les préoccupations à long terme comme la santé du cœur et des os. La promotion de la santé met en relief les bienfaits de l’activité chez les survivantes du cancer, avec l’accent mis sur l’activité physique. Les soins aux survivantes sont de meilleure qualité lorsque divers services et professionnels de la santé participent aux soins, et le médecin de famille joue un rôle important dans la coordination des soins. Conclusion Les médecins de famille sont de plus en plus souvent les principaux fournisseurs de soins de suivi après le traitement du cancer du sein. Le cancer du sein doit être considéré comme une affection médicale chronique, même chez les femmes en rémission, et les patientes profitent de la même approche que celle utilisée pour les autres affections chroniques en

Endocytosis in the Shiitake Mushroom Lentinula edodes and Involvement of GTPase LeRAB7▿

PubMed Central

Lee, Ming Tsung; Szeto, Carol Ying Ying; Ng, Tak Pan; Kwan, Hoi Shan

2007-01-01

Endocytosis is the process by which substrates enter a cell without passing through the plasma membrane but rather invaginate the cell membrane and form intracellular vesicles. Rab7 regulates endocytic trafficking between early and late endosomes and between late endosomes and lysosomes. LeRab7 in Lentinula edodes is strongly homologous to Rab7 in Homo sapiens. Receptors for activated C kinase-1 (LeRACK1) and Rab5 GTPase (LeRAB5) were isolated as interacting partners of LeRab7, and the interactions were confirmed by in vivo and in vitro protein interaction assays. The three genes showed differential expression in the various developmental stages of the mushroom. In situ hybridization showed that the three transcripts were localized in regions of active growth, such as the outer region of trama cells, and the subhymenium of the hymenophore of mature fruiting bodies and the prehymenophore of young fruiting bodies. The existence of endocytosis in the mycelium and hymenophores was confirmed by the internalization of FM4-64. LeRAB7 was partially colocalized with the AM4-64 and was located in the late endocytic pathway. This is the first report of the presence of endocytosis in homobasidiomycetes. LeRAB7, LeRAB5, and LeRACK1 may contribute to the growth of L. edodes and cell differentiation in hymenophores. PMID:17921351

Beyond ‘MSM’: Sexual Desire Among Bisexually-Active Latino Men in New York City

Muñoz-Laboy, Miguel A.

2015-01-01

Latino male bisexuality has been studied for the most part with a focus on men who have sex with men (MSM) and with little attention to sexual desire. The goal of this article is to present a comprehensive understanding of how sexual desire is organized, enacted through sexual activity, and interpreted in the sexual lives of bisexually-active Latino men. To achieve this aim, an analysis was made of 18 sexual histories of bisexually active Latino men who participated in a two-year ethnographic study. Four configurations of sexual desire were constructed to reflect what was found in this population of bisexually-active Latino men: (a) lifetime homoerotic desire and casual sex with women; (b) lifetime heteroerotic desire, but commercial sex with men; (c) lifetime heteroerotic/transgender desire; (d) lifetime sexual desire for women and men. These configurations are explored in detail in this article. The analysis presented here is intended to offer insights into the overall study of Latino male bisexuality and into the foundations for the design of HIV and STI prevention programs directed toward bisexually-active Latino men and their partners.

Windwer, C

1977-01-01

This study sought to determine if there is a relationship among locus of control, social desirability, and choice of psychoprophylaxis (PPM). It was hypothesized that internal locus of control and low social desirability would correlate significantly with the choice of PPM by husbands and wives; that externally controlled wives who participated in PPM would have more internally controlled husbands than externally controlled wives who participated in PPM would have more internally controlled husbands than externally controlled wives who did not participate; and that locus of control and social desirability, when taken together, would be better predictors of choice of PPM than either taken separately. Ninety-eight middle-class nulliparous couples, participant and non-participant, were studied in the seventh or eighth month of the wife's pregnancy. Rotter's I-E Scale and the Marlowe-Crowne Social Desirability Scale were used to measure locus of control and social desirability. Study findings did not support the hypotheses.

Desired emotional states: their nature, causes, and implications for emotion regulation.

PubMed

Tamir, Maya; Gutentag, Tony

2017-10-01

Emotion regulation is a process directed toward achieving desired emotions. People want to experience different emotions at different times and for different reasons, leading them to change emotions accordingly. Research on desired emotions has made several discoveries. First, what people want to feel varies across individuals and across situations. Second, what people want to feel depends on how much they value emotions and on the extent to which they expect emotions to yield behavioral, social, or epistemic benefits. Third, what people want to feel sets the direction of emotion regulation and can shape emotional experiences and subsequent behavior. Identifying and understanding desired emotional states can promote healthier emotion regulation and emotional experiences, and more adaptive personal and social functioning.

Probing the implicit suicidal mind: does the Death/Suicide Implicit Association Test reveal a desire to die, or a diminished desire to live?

PubMed

Harrison, Dominique P; Stritzke, Werner G K; Fay, Nicolas; Ellison, T Mark; Hudaib, Abdul-Rahman

2014-09-01

Assessment of implicit self-associations with death relative to life, measured by a death/suicide implicit association test (d/s-IAT), has shown promise in the prediction of suicide risk. The current study examined whether the d/s-IAT reflects an individual's desire to die or a diminished desire to live and whether the predictive utility of implicit cognition is mediated by life-oriented beliefs. Four hundred eight undergraduate students (285 female; Mage = 20.36 years, SD = 4.72) participated. Participants completed the d/s-IAT and self-report measures assessing 6 indicators of suicide risk (suicide ideation frequency and intensity, depression, nonsuicidal self-harm thoughts frequency and intensity, and nonsuicidal self-harm attempts), as well as survival and coping beliefs and history of prior suicide attempts. The d/s-IAT significantly predicted 5 out of the 6 indicators of suicide risk above and beyond the strongest traditional indicator of risk, history of prior suicide attempts. However, the effect of the d/s-IAT on each of the risk indicators was mediated by individuals' survival and coping beliefs. Moreover, the distribution of d/s-IAT scores primarily reflected variability in self-associations with life. Implicit suicide-related cognition appears to reflect a gradual diminishing of the desire to live, rather than a desire to die. Contemporary theories of suicide and risk assessment protocols need to account for the dynamic relationship between both risk and life-oriented resilience factors, and intervention strategies aimed at enhancing engagement with life should be a routine part of suicide risk management.

Media Impacts on Women's Fertility Desires: A Prolonged Exposure Experiment.

PubMed

Knobloch-Westerwick, Silvia; Willis, Laura E; Kennard, Ashley R

2016-06-01

Media exposure may have implications for family planning, a public health issue of key importance. Drawing on social comparison theory and social identity theory, a prolonged exposure experiment examined whether media portrayals of women's social roles affect fertility desires among 166 American, nonstudent, never married, childless women ages 21-35 years old. After sign-up and baseline sessions, participants viewed magazine pages five days in a row. Stimuli presented women in either mother/homemaker roles, beauty ideal roles, or professional roles. Three days later, participants again indicated their number of desired children and time planned until first birth. Exposure to mother/homemaker and beauty ideal portrayals increased the number of desired children across time. Exposure to professional portrayals increased the time planned until 1st birth compared to beauty ideal portrayals-this impact was partially mediated by a shift toward more progressive gender norms (per social identity theory) and assimilation (per social comparison theory).

Culpabilité chez les enfants victimes d’agression sexuelle : Le rôle médiateur des stratégies d’évitement sur l’anxiété et l’estime de soi

Résumé Des études antérieures relèvent que le sentiment de culpabilité est un facteur associé aux répercussions de l’agression sexuelle (AS) chez les survivants adultes (Cantón-Cortés, Cantón, Justicia et Cortés, 2011). Toutefois, très peu d’études ont exploré le rôle potentiel du sentiment de culpabilité sur les symptômes chez les enfants victimes. L’objectif de cette recherche est d’étudier le rôle médiateur de l’évitement dans la relation entre le sentiment de culpabilité et les symptômes associés à l’AS (anxiété et estime de soi). L’échantillon est composé de 447 enfants victimes d'AS (319 filles et 128 garçons), âgés de 6 à 12 ans. Les résultats des analyses acheminatoires indiquent que les enfants révélant davantage de culpabilité par rapport à la situation d’AS présentent un niveau plus élevé d’anxiété et une plus faible estime d’eux-mêmes. Un effet indirect a également été observé et montre que le sentiment de culpabilité est lié à l’utilisation de stratégies d’évitement, qui en retour exacerbent les symptômes d’anxiété et contribuent à une plus faible estime de soi. Le modèle, qui s’ajuste aux données de manière équivalente pour les filles et les garçons, permet d’expliquer 24,4 % de la variance des symptômes d’anxiété et 11,2 % de la variance de l’estime de soi. Ces résultats laissent entendre que le sentiment de culpabilité pourrait constituer une cible d’intervention pertinente pour les enfants victimes d’AS. PMID:29445251

[Desire for amputation in body integrity identity disorder].

PubMed

Blom, Rianne M; Hennekam, Raoul C M

2014-01-01

Body integrity identity disorder (BIID) is a rare neuropsychiatric disorder in which patients experience a mismatch between the real and experienced body from childhood. BIID results in a strong desire to amputate or paralyse one or more limbs. We describe two BIID patients. A 40-year-old healthy male suffered daily from his desire for amputation, and therefore made a request for amputation at our academic medical centre. A 61-year-old male proceeded to self-amputation to create the body he had wished for, thereby curing himself from BIID. To date, no treatment has been found for BIID. Therefore patients often proceed to self-amputation, which could lead to serious and even dangerous complications. These case histories suggest that elective amputation may be a treatment for BIID. Many doctors, however, will question the admissibility of amputation of a healthy limb.

Shikonin is a naphthoquinone secondary metabolite with important medicinal value and is found in Lithospermum erythrorhizon. Considering the limited knowledge on the membrane transport mechanism of shikonin, this study investigated such molecular mechanism. We successfully isolated an ATP-binding cassette protein gene, LeMDR, from L. erythrorhizon. LeMDR is predominantly expressed in L. erythrorhizon roots, where shikonin accumulated. Functional analysis of LeMDR by using the yeast cell expression system revealed that LeMDR is possibly involved in the shikonin efflux transport. The accumulation of shikonin is lower in yeast cells transformed with LeMDR-overexpressing vector than that with empty vector. The transgenic hairy roots of L. erythrorhizon overexpressing LeMDR (MDRO) significantly enhanced shikonin production, whereas the RNA interference of LeMDR (MDRi) displayed a reverse trend. Moreover, the mRNA expression level of LeMDR was up-regulated by treatment with shikonin and shikonin-positive regulators, methyl jasmonate and indole-3-acetic acid. There might be a relationship of mutual regulation between the expression level of LeMDR and shikonin biosynthesis. Our findings demonstrated the important role of LeMDR in transmembrane transport and biosynthesis of shikonin.

Patterns of Asexuality in China: Sexual Activity, Sexual and Romantic Attraction, and Sexual Desire.

PubMed

Zheng, Lijun; Su, Yanchen

2018-05-01

This study examined patterns of asexuality in Chinese asexual people in terms of sexual activities, sexual/romantic attraction, and sexual desire. The sample included 227 (64 men and 163 women) asexual participants and 57 (26 men and 31 women) uncertain asexual participants recruited from social networks for asexual people. The control group included 217 (115 men and 102 women) heterosexual participants recruited from general social networks. Participants scoring 40 or higher on the Asexuality Identification Scale were classified as asexual. Asexual participants reported having less frequent masturbation, sexual intercourse experience, and sexual and romantic attraction compared to heterosexual participants. Lower sexual attraction among asexuals indicated that "people who experience little or no sexual attraction" would be a more appropriate definition of asexuality. The pattern of uncertain asexual participants' sexual/romantic attraction and sexual desire was intermediate between heterosexual and asexual participants. Asexual participants scored significantly lower on dyadic sexual desire and slightly lower on solitary sexual desire than heterosexual participants. There were significant differences in sexual activities and solitary sexual desire among romantic orientation categories. Homoromantic participants showed higher dyadic sexual desire and were more likely to engage in masturbation, indicating the heterogeneity among asexual people. The findings indicated that Chinese asexual people showed similar patterns of asexuality as in Western nations. Specifically, asexual people have little or no sexual attraction, non-partner-orientated sexual desire, and are heterogeneous in sexual activities and sexual desire. This implies similar mechanisms underlying the etiology of asexuality across cultures.

Notre methode generalise l'approximation auto-coherente a deux particules proposee par Vilk et Tremblay pour le modele de Hubbard repulsif. Notre methode peut s'appliquer a l'etude du comportement pre-critique lorsque la symetrie du parametre d'ordre est suffisamment elevee. Nous appliquons la methode au probleme du pseudogap dans le modele de Hubbard attractif. Nos resultats montrent un excellent accord avec les donnees Monte Carlo pour de petits systemes. Nous observons que le regime ou apparait le pseudogap dans le poids spectral a une particule est un regime classique renormalise caracterise par une frequence caracteristique des fluctuations supraconductrices inferieure a la temperature. Une autre caracteristique est la faible densite de superfluide de cette phase demontrant que nous ne sommes pas en presence de paires preformees. Les resultats obtenus semblent montrer que la haute symetrie du parametre d'ordre et la bidimensionalite du systeme etudie elargissent le domaine de temperature pour lequel le regime pseudogap est observe. Nous argumentons que ce resultat est transposable aux supraconducteurs a haute temperature critique ou le pseudogap apparait a des' temperatures beaucoup plus grandes que la temperature critique. La forte symetrie dans ces systemes pourraient etre reliee a la theorie SO(5) de Zhang. En annexe, nous demontrons un resultat tout recent qui permettrait d'assurer l'auto-coherence entre les proprietes a une et a deux particules par l'ajout d'une dynamique au vertex irreductible. Cet ajout laisse entrevoir la possibilite d'etendre la methode au cas d'une forte interaction.

Pertinence de l'implantation de la filiere granule de bois pour le Quebec

NASA Astrophysics Data System (ADS)

Tremblay, Stephan

Les spécialistes avancent que le marché mondial de l'énergie en forte demande et en offre limitée nécessitera bientôt toutes les formes d'énergie disponibles. Le granulé de bois est une forme de bioénergie principalement utilisée pour le chauffage des bâtiments et pourrait être davantage considéré dans l'offre énergétique du Québec. Comme le Québec est un territoire où il fait froid et donc susceptible de pouvoir se tourner vers cette forme d'énergie, l'objectif de ce mémoire est d'en analyser les avantages. Pour ce faire, nous commencerons par démontrer la croissance des besoins énergétiques sur les plans national et international et dresser un portrait des différentes formes d'énergies consommées au Québec. Puisque la majorité des Québécois chauffent leurs bâtiments à l'hydroélectricité, nous analyserons à travers le plan d'approvisionnement d'Hydro-Québec le portrait de la production et de la consommation de cette forme d'énergie renouvelable. Cela nous permettra de constater le défi face à la gestion de surplus importants, sauf pendant la période hivernale, et ce faisant, l'obligation de la société d'État d'utiliser davantage ses centrales au gaz ou de se tourner vers l'importation de l'électricité. Dans la même lignée, un regard sera porté sur les perspectives d'utilisation de l'hydroélectricité sur les plans de la production d'aluminium, de l'exportation et de l'utilisation dans l'électrification des transports au Québec. Cette analyse se fera dans l'objectif de s'interroger sur la pertinence d'utiliser cette source d'énergie dans le chauffage plutôt que dans des secteurs plus créateurs de richesse. Nous poserons ensuite l'hypothèse que le granulé de bois pourrait être un bon substitut à une autre forme d'énergie utilisée dans le chauffage, soit le mazout. Avant de dresser un portrait de ce combustible fossile, nous ferons celui de la production et de la consommation de granulés sur les plans r

Like mother, like child: Offspring marital timing desires and maternal marriage timing and stability.

PubMed

Arocho, Rachel; Kamp Dush, Claire M

2017-04-01

Understanding the determinants of marital timing is critical because it has implications for marital functioning and divorce. One salient predictor of marital timing is youth's desires for marriage timing. To shine light on predictors of both desires for marital timing and the timing of marriage itself, we examine offspring marital desires and maternal marriage characteristics in the National Longitudinal Survey of Youth, 1979 (NLSY79) cohort and 1979 Child and Young Adult cohort (NLSY79-CYA; biological offspring of the women in the 1979 cohort). Analyses showed that maternal cohabitation postdivorce predicted decreased expectations to ever marry in offspring. Maternal age at marriage was positively associated with offspring desires for age at marriage, but only for those whose mothers had not divorced. Maternal marital age was significantly associated with the offspring's transition into marriage even when controlling for the offspring's desires for marriage timing, but neither maternal marriage age nor offspring desires for marital timing were associated with the timing of entrance into cohabitation, whereas maternal divorce was associated with earlier cohabitation. Our findings suggest that maternal marriage characteristics, particularly divorce, are significant predictors of millennials' desires for and experiences with romantic relationships.

Is subcranial Le Fort III plus Le Fort I osteotomy stable?

PubMed

Boos Lima, Fernanda Brasil Daura Jorge; Hochuli Vieira, Eduardo; Juergens, Philipp; Lima Junior, Sergio Monteiro

2017-12-01

The purpose of this study was to test whether associated subcranial Le Fort III (sLF III) and Le Fort I (LF I) osteotomies are stable after large advancements of the middle third of the face and maxilla. The authors designed a retrospective study and enrolled a sample of consecutive patients with midface hypoplasia treated with associated sLF III and LF I osteotomies in this IRB-approved study between September 2013 and February 2015. To test whether the long-term stability was satisfactory, the authors compared cephalometric changes from immediately after surgery to 18 months after surgery taken from multi-slice computed tomography using two different third-party imaging software programs. Statistical significance was set as P ≤ 0.05. The sample comprised 11 patients (mean age 23.84 ± 4.17 yr; 54% men). The mean advancement of the upper incisor immediately after surgery was 10.03 ± 1.6 mm. After 18 months, the position of the upper incisor did not vary significantly (10.18 ± 2.35 mm). All other cephalometric landmarks did not present statistically significant differences between immediately after and 18 months after surgery, with horizontal and vertical variations of less than one millimetre. This study supports that sLF III and LF I osteotomies are effective in maintaining stable horizontal and vertical skeletal positioning after surgery.

The power of synthetic biology has enabled the expression of heterologous pathways in cells, as well as genome-scale synthesis projects. The complexity of biological networks makes rational de novo design a grand challenge. Introducing features that confer genetic flexibility is a powerful strategy for downstream engineering. Here we develop an in vitro method of DNA library construction based on structural variation to accomplish this goal. The "in vitro SCRaMbLE system" uses Cre recombinase mixed in a test tube with purified DNA encoding multiple loxPsym sites. Using a β-carotene pathway designed for expression in yeast as an example, we demonstrate top-down and bottom-up in vitro SCRaMbLE, enabling optimization of biosynthetic pathway flux via the rearrangement of relevant transcription units. We show that our system provides a straightforward way to correlate phenotype and genotype and is potentially amenable to biochemical optimization in ways that the in vivo system cannot achieve.

Do users desire symmetrical lumbar supports in task seating?

Fredericks, Tycho K; Butt, Steven E; Kumar, Anil R; Bellingar, Teresa

2016-07-01

This research was designed to objectively investigate the desired low back (lumbar) support in a task chair; specifically by allowing a user to self-select the magnitude and location of support. An experimental chair built specifically for this study allowed the users to remotely adjust 35 diodes to achieve their desired level of support. Pressure mapping was used to measure the interface pressure at the user-seat back interface. It was determined that 73.8% of the 201 participants in this study, self-selected asymmetrical lower back support that was at least 20% greater on one side vs. the other. Additionally, 16.9% of the participants self-selected support on one side which was at least twice that of the other side. Contrary to popular practice, participants were found to prefer asymmetric support in the lower back region. It is anticipated that the culmination of this research will aid chair manufacturers in designing adaptable back rests. Practitioner Summary: Most current lumbar supports are designed to move vertically and to symmetrically increase or decrease in firmness as per a user's adjustment. This investigation highlights that participants tended to select asymmetrical lumbar support, and as such, designers should consider providing lumbar supports that provide the desired support at appropriate locations.

Just Blowing Smoke? Social Desirability and Reporting of Intentions to Quit Smoking

PubMed Central

2013-01-01

Introduction: Do cigarette smokers really want to quit smoking or do they simply say they do in order to placate others and avoid criticism? In surveys of smokers, stated quit intentions and reports of quit attempts may be biased by social desirability concerns. This makes it difficult to interpret large-scale state and national surveys of smoking behavior that collect data through telephone and face-to-face interviews, methods that tend to evoke high levels of socially desirable responding. Methods: The 2007 Health Information National Trends Survey used a dual-frame design to query smokers’ quit intentions and past quit attempts in 1 of 2 ways: A self-administered mail survey (low pressure for socially desirable responding; n = 563), or an interviewer-administered telephone survey (high pressure for socially desirable responding; n = 499). Estimates derived from the 2 formats were compared to test for social desirability effects. Results: In both survey modes, approximately two thirds of smokers reported seriously considering quitting in the next 6 months (mail: 64.9%; telephone: 68.9%), and approximately half reported making a quit attempt in the past year (mail: 54.9%; telephone: 52.3%). Neither difference approached significance in logistic regressions controlling for demographics (ps > .24). Conclusions: It appears that a large proportion of smokers in the United States aspire to live smoke-free lives and are not simply responding in a socially desirable manner to deflect criticism in an antismoking social climate. Future research should (1) replicate this study with greater statistical power, (2) examine the possible effects of survey context (e.g., health survey vs. smoking pleasure survey), and (3) explore survey mode effects in specific subpopulations.

STUDYING TRAVEL-RELATED INDIVIDUAL ASSESSMENTS AND DESIRES BY COMBINING HIERARCHICALLY STRUCTURED ORDINAL VARIABLES

PubMed Central

Song, Tingting; Wittkowski, Knut M.

2010-01-01

Ordinal measures are frequently encountered in travel behavior research. This paper presents a new method for combining them when a hierarchical structure of the data can be presumed. This method is applied to study the subjective assessment of the amount of travel by different transportation modes among a group of French clerical workers, along with the desire to increase or decrease the use of such modes. Some advantages of this approach over traditional data reduction technique such as factor analysis when applied to ordinal data are then illustrated. In this study, combining evidence from several variables sheds light on the observed moderately negative relationship between the personal assessment of the amount of travel and the desire to increase or decrease it, thus integrating previous partial (univariate) results. We find a latent demand for travel, thus contributing to clarify the behavioral mechanisms behind the induced traffic phenomenon. Categorizing the above relationship by transportation mode shows a desire for a less environmental-friendly mix of modes (i.e. a greater desire to use heavy motorized modes and a lower desire to use two-wheeled modes), whenever the respondents do not feel to travel extensively. This result, combined with previous theoretical investigations concerning the determinants of the desire to alter trips consumption levels, shows the importance of making people aware of how much they travel.

2014-03-01

Retinoids, through their activation of retinoic acid receptors (RARs) and retinoid X receptors, regulate diverse cellular processes, and pharmacological intervention in their actions has been successful in the treatment of skin disorders and cancers. Despite the many beneficial effects, administration of retinoids causes irritating side effects with unknown mechanisms. Here, we demonstrate that LE135 [4-(7,8,9,10-tetrahydro-5,7,7,10,10-pentamethyl-5H-benzo[e]naphtho[2,3-b][1,4]diazepin-13-yl)benzoic acid], a selective antagonist of RARβ , is a potent activator of the capsaicin (TRPV1) and wasabi (TRPA1) receptors, two critical pain-initiating cation channels. We performed to investigate the excitatory effects of LE135 on TRPV1 and TRPA1 channels expressed in HEK293T cells and in dorsal root ganglia neurons with calcium imaging and patch-clamp recordings. We also used site-directed mutagenesis of the channels to determine the structural basis of LE135-induced activation of TRPV1 and TRPA1 channels and behavioural testing to examine if pharmacological inhibition and genetic deletion of the channels affected LE135-evoked pain-related behaviours. LE135 activated both the capsaicin receptor (TRPV1) and the allyl isothiocyanate receptor (TRPA1) heterologously expressed in HEK293T cells and endogenously expressed by sensory nociceptors. Mutations disrupting the capsaicin-binding site attenuated LE135 activation of TRPV1 channels and a single mutation (K170R) eliminated TRPA1 activity evoked by LE135. Intraplantar injection of LE135 evoked pain-related behaviours. Both TRPV1 and TRPA1 channels were involved in LE135-elicited pain-related responses, as shown by pharmacological and genetic ablation studies. This blocker of retinoid acid signalling also exerted non-genomic effects through activating the pain-initiating TRPV1 and TRPA1 channels. © 2013 The British Pharmacological Society.

Gender moderates the effects of independence and dependence desires during the social support process.

2004-03-01

This investigation examined the roles of gender and desires for independence and dependence in the support process. We assessed 118 older adults who reported needing help with at least 1 activity of daily living as a result of illness or health problems. Men with a high desire to be independent responded negatively to receiving support from their social network. Women's outcomes were generally unaffected by their independence and dependence desires. These results indicate that gender and desires for independence and dependence should be taken into account when examining the social support process, especially in men with health problems.

Résumé Objectif Exposer l’efficacité et les risques du traitement par les bisphosphonates dans la prise en charge de l’ostéoporose et décrire les patients qui seraient de bons candidats aux congés thérapeutiques. Qualité des données Une recherche dans MEDLINE (PubMed, jusqu’au 31 décembre 2012) a permis de relever les publications pertinentes pour l’inclusion. La plupart des données probantes citées sont de niveau II (tirées d’essais non randomisés, de cohorte et d’autres essais comparatifs). Message principal L’efficacité des bisphosphonates de premier recours homologués pour la prévention des fractures a été éprouvée dans le cadre d’essais cliniques randomisés et contrôlés. Cependant, l’usage clinique répandu et prolongé des bisphosphonates a donné lieu à des rapports de manifestations indésirables rares, mais graves. L’ostéonécrose maxillaire et les fractures atypiques sous-trochantériennes ou diaphysaires du fémur seraient liées à l’emploi des bisphosphonates dans le traitement de l’ostéoporose, mais ces manifestations sont extrêmement rares et lorsqu’elles surviennent, elles sont accompagnées d’autres comorbidités ou de l’emploi concomitant de médicaments. Les congés thérapeutiques ne peuvent être envisagés que chez les patients à faible risque et dans un groupe restreint de patients dont le risque de fracture est modéré après un traitement de 3 à 5 ans. Conclusion Lorsque les bisphosphonates sont prescrits à des patients dont le risque de fracture est élevé, leur effet de prévention des fractures l’emporte de loin sur leurs torts potentiels. Chez les patients qui prennent des bisphosphonates depuis 3 à 5 ans, il faut réévaluer le besoin de poursuivre le traitement.

Producing desired ice faces

2015-01-01

The ability to prepare single-crystal faces has become central to developing and testing models for chemistry at interfaces, spectacularly demonstrated by heterogeneous catalysis and nanoscience. This ability has been hampered for hexagonal ice, Ih––a fundamental hydrogen-bonded surface––due to two characteristics of ice: ice does not readily cleave along a crystal lattice plane and properties of ice grown on a substrate can differ significantly from those of neat ice. This work describes laboratory-based methods both to determine the Ih crystal lattice orientation relative to a surface and to use that orientation to prepare any desired face. The work builds on previous results attaining nearly 100% yield of high-quality, single-crystal boules. With these methods, researchers can prepare authentic, single-crystal ice surfaces for numerous studies including uptake measurements, surface reactivity, and catalytic activity of this ubiquitous, fundamental solid.

Chen, H

1997-08-01

This article presents findings from a 1995 survey of fertility intentions, among married women of childbearing age, in urban and rural Tibet Autonomous Region, China. The survey was conducted by the Population Research Institute of the University of Tibet. The sample included 857 women, of whom 59.2% were aged 20-34 years. Women desired 2-3 births. About 55% desired 2 children, 10% desired 1 child, 23% desired 3 children, and 11% desired 4 or more children. Tibetan women still believe that children are important for supporting aging parents and to continue the family line. A few still believe in the traditional view that God decides the number of children. Educational status was associated with average current births. Women with higher education had fewer births. Herdsmen, with an average annual income per capita of 400 yuan, had the highest average number of children of 2.71. Government employees, who had an annual per capita income of 2000 yuan, had the lowest average number of children of 1.70. 569 women said that the sex of the child was not an issue. 250 women preferred boys to girls due to the harsh local natural environment and finances. 72.23% of women hoped that their children would receive higher education and be useful to society. 89% of women were satisfied with the present family planning (FP) policy in Tibet. The interviewers recommend that the government give FP policy publicity priority and improve the quality of FP services. Improvements should include stronger health institutions, training of health care providers, quality technical services, and better natural environment and socioeconomic conditions.

Architectural Kansei of ‘Wall’ in The Façade Design by Le Corbusier

NASA Astrophysics Data System (ADS)

Sendai, Shoichiro

The purpose of this paper is to discuss the modern architect Le Corbusier's architectural Kansei (sensibility) on wall in site environment through the analysis of his façade design, using Œuvres complètes (1910-1965, 8 vols., Les éditions d'architecture, Artemis, Zurich) and Le Corbusier Archives (1982-1984, 32 vols., Garland Publishing, Inc. and Fondation Le Corbusier, New York, London, Paris). At first, I arrange five façade types, according to the explanation by Le Corbusier ; ‘fenêtre en longueur (strip window)’, ‘pan de verre (glass wall)’, ‘brise-soleil (sun-breaker)’, ‘loggia’ and ‘claustra’. Through the analysis of the relationship between these types and the design process of each building, we find that Le Corbusier's façade design includes the affirmation and the negation of the ‘wall’ at the same time. In fact, the nature of façade modification during design process is divers: increase in transparency, decrease in transparency and spatialization of façade. That means, Le Corbusier studied the environmental condition by these façade types, and tried to realize the phenomenal openness. This trial bases on the function of architectural Kansei as correspondence between body and environment beyond the physical design.

Desired machines: cinema and the world in its own image.

PubMed

Canales, Jimena

2011-09-01

In 1895 when the Lumière brothers unveiled their cinematographic camera, many scientists were elated. Scientists hoped that the machine would fulfill a desire that had driven research for nearly half a century: that of capturing the world in its own image. But their elation was surprisingly short-lived, and many researchers quickly distanced themselves from the new medium. The cinematographic camera was soon split into two machines, one for recording and one for projecting, enabling it to further escape from the laboratory. The philosopher Henri Bergson joined scientists, such as Etienne-Jules Marey, who found problems with the new cinematographic order. Those who had worked to make the dream come true found that their efforts had been subverted. This essay focuses on the desire to build a cinematographic camera, with the purpose of elucidating how dreams and reality mix in the development of science and technology. It is about desired machines and their often unexpected results. The interplay between what "is" (the technical), what "ought" (the ethical), and what "could" be (the fantastical) drives scientific research.

Shikonin and its derivatives are important medicinal secondary metabolites accumulating in roots of Lithospermum erythrorhizon. Although some membrane proteins have been identified as transporters of secondary metabolites, the mechanisms underlying shikonin transport and accumulation in L. erythrorhizon cells still remain largely unknown. In this study, we isolated a cDNA encoding LeMRP, an ATP-binding cassette transporter from L. erythrorhizon, and further investigated its functions in the transport and biosynthesis of shikonin using the yeast transformation and transgenic hairy root methods, respectively. Real-time PCR was applied for expression analyses of LeMRP and shikonin biosynthetic enzyme genes. Functional analysis of LeMRP using the heterologous yeast cell expression system showed that LeMRP could be involved in shikonin transport. Transgenic hairy roots of L. erythrorhizon demonstrated that LeMRP overexpressing hairy roots produced more shikonin than the empty vector (EV) control. Real-time PCR results revealed that the enhanced shikonin biosynthesis in the overexpression lines was mainly caused by highly up-regulated expression of genes coding key enzymes (LePAL, HMGR, Le4CL and LePGT) involved in shikonin biosynthesis. Conversely, LeMRP RNAi decreased the accumulation of shikonin and effectively down-regulated expression level of the above genes. Typical inhibitors of ABC proteins, such as azide and buthionine sulphoximine, dramatically inhibited accumulation of shikonin in hairy roots. Our findings provide evidence for the important direct or indirect role of LeMRP in transmembrane transport and biosynthesis of shikonin. © 2017 German Society for Plant Sciences and The Royal Botanical Society of the Netherlands.

Influence of social desirability on age differences in self-reports of mood and personality

PubMed Central

Soubelet, Andrea; Salthouse, Timothy A.

2011-01-01

Increased age has been found to be associated with differences in affect and personality which have been interpreted in terms of better emotional regulation and increased maturity. However, these findings have largely been based on self-report data, and the primary goal of the current research was to investigate the hypothesis that age-related differences in affect and in certain desirable personality traits might, at least partially, reflect age differences in social desirability. As expected, increased age was associated with lower levels of negative affect and neuroticism and higher levels of positive affect, life satisfaction, agreeableness and conscientiousness, and scores on the social desirability scale were positively related to age and to desirable self-report characteristics, but negatively related to undesirable self-report characteristics. Importantly, controlling for the variance in the social desirability measure resulted in less positive age trends in both types of self-report measures. PMID:21682727

2012-08-01

Homosexual parents as well as gay and lesbian individuals wanting children are increasingly a topic of public discourse. To estimate the importance of parenting for this group, 1 289 non-heterosexual individuals were examined by means of an anonymous online survey. Their answers were compared to 1 022 heterosexual participants of a representative control group. The respondents were questioned concerning their motives for desiring children, the external factors influencing this desire and their ideal number of children. 80% of the non-heterosexual respondents and 49% of the control group indicated that they have no children. In both groups emotional motives were reported to have far greater influence on their parenting desire than social recognition or personal and financial constraints. 85% of the non-heterosexual respondents and 60% of the control group have fewer children than they would like to have. Both groups considered work and their financial situation as the most important external factors influencing the realization of their desire to have children. © Georg Thieme Verlag KG Stuttgart · New York.

Normative discourses on the desire to have children.

PubMed

Vargas, Eliane Portes; Moás, Luciane da Costa

2010-08-01

Reflections on normative discourses on sexuality, family and reproduction are shown, promoted by medical and juridical knowledge in modern society. This study was based on the assumption that changes and maintenance of values and practices coexist in the current discourses on the desire to have children, expressed as claims in the dimension of sexual and reproductive rights, with new demands in the sphere of public and health policies. The current value attributed to family is founded on the model of modern conjugal family, which can be observed in the changes that have occurred in family relations and sexual identities. Based on a new configuration of values, the expectation of paternity and maternity has partly become a value of the homosexual relationship. However, despite changes in the sphere of family relations and social identities, the centrality of the heterosexual couple prevails in the medical and juridical discourse on the desire to have children.

Actual and desired information provision after a stroke.

2005-02-01

Stroke patients and caregivers have a substantial information need. The study investigates how information was actually provided to stroke patients and caregivers and how they prefer to be informed. The GP, neurologist and physiotherapist are both the actual and desired information providers. The actual and desired information correspond in terms of content, frequency, and method of presentation. However, patients and caregivers prefer to receive information within 24 h and to be informed about, and be given, relevant written information. The information given by the various professional stroke care-providers could be better co-ordinated. The role of the GP as an information provider lagged quite a long way behind. Recommendations for the provision of an improved information system is given. Most of the subjects are relatively young male patients with few disabilities and healthy caregivers. More attention should be paid to encouraging patients and caregivers to actively seek information to supplement the information given by professional stroke care-providers.

Tradition and the individual sodomite: Barnfield, Shakespeare, and subjective desire.

PubMed

Bredbeck, G W

1992-01-01

This article compares Shakespeare's sonnets with those written by Richard Barnfield in order to examine the possibility of homoerotic subjectivity in early Renaissance England. Social constructionist debates about sexual subjectivity have convincingly argued that "the homosexual"--the person defined by homosexuality--did not exist before the Enlightenment. The sequences of Shakespeare and Barnfield, both of which deal with homoerotic desire, suggest that homoerotic desire could indeed play a role in defining the individuated subject prior to the Enlightenment. However, the ways in which they use homoeroticism also suggest that subjectivity was defined in radically different ways during the period.

Reduced labial temperature in response to sexual films with distractors among women with lower sexual desire.

PubMed

Prause, Nicole; Heiman, Julia

2010-02-01

Sexual desire variation traditionally has been treated as due to variance in affective response to sexual stimulation, but differences in attention to the stimuli may better account for differences in sexual desire. Determine whether sexual desire varies due to attention biases towards sexual stimuli. Sexual arousal was quantified by physiological (labia minus temperature) and experienced (continuously adjusting a potentiometer) indicators. Twenty-two women who varied in their level of sexual desire attended one laboratory session during which they viewed a neutral nature film, a sexual film, and a sexual film with distractors while their labial temperature and self-reported sexual arousal were recorded. Participants reported and displayed lower sexual arousal during the sexual stimulus with distractors as compared to the sexual film without distractors. While all women reported lower sexual arousal to the sexual film with distractors, women with relatively lower sexual desire also reported lower sexual arousal to the sexual film with no distractors than women with higher sexual desire. Physiologically, women with lower sexual desire exhibited lower labial temperature. Since the predicted lower self-reported and physiological sexual arousal to the sexual stimulus with distractors for the women with lower sexual desire did not emerge, this study does not support that sexual desire levels vary due to differential attention to sexual stimuli.

Modelisation frequentielle de la permittivite du beton pour le controle non destructif par georadar

NASA Astrophysics Data System (ADS)

Bourdi, Taoufik

Le georadar (Ground Penetrating Radar (GPR)) constitue une technique de controle non destructif (CND) interessante pour la mesure des epaisseurs des dalles de beton et la caracterisation des fractures, en raison de ses caracteristiques de resolution et de profondeur de penetration. Les equipements georadar sont de plus en plus faciles a utiliser et les logiciels d'interpretation sont en train de devenir plus aisement accessibles. Cependant, il est ressorti dans plusieurs conferences et ateliers sur l'application du georadar en genie civil qu'il fallait poursuivre les recherches, en particulier sur la modelisation et les techniques de mesure des proprietes electriques du beton. En obtenant de meilleures informations sur les proprietes electriques du beton aux frequences du georadar, l'instrumentation et les techniques d'interpretation pourraient etre perfectionnees plus efficacement. Le modele de Jonscher est un modele qui a montre son efficacite dans le domaine geophysique. Pour la premiere fois, son utilisation dans le domaine genie civil est presentee. Dans un premier temps, nous avons valide l'application du modele de Jonscher pour la caracterisation de la permittivite dielectrique du beton. Les resultats ont montre clairement que ce modele est capable de reproduire fidelement la variation de la permittivite de differents types de beton sur la bande de frequence georadar (100 MHz-2 GHz). Dans un deuxieme temps, nous avons montre l'interet du modele de Jonscher en le comparant a d'autres modeles (Debye et Debye-etendu) deja utilises dans le domaine genie civil. Nous avons montre aussi comment le modele de Jonscher peut presenter une aide a la prediction de l'efficacite de blindage et a l'interpretation des ondes de la technique GPR. Il a ete determine que le modele de Jonscher permet de donner une bonne presentation de la variation de la permittivite du beton dans la gamme de frequence georadar consideree. De plus, cette modelisation est valable pour differents

Measurement of sexual function typically uses self-report, which, to work as intended, must use language that is understood consistently by diverse respondents. Commonly used measures employ multiple terms, primarily (sexual) interest, desire, and arousal, that might not be understood in the same way by laypeople and professionals. To inform self-reported measurement efforts for research and clinical settings by examining how US men and women recruited from a health care setting understand and interpret different terms. We conducted 10 focus groups in Durham, NC (N = 57). Discussions were audio-recorded and transcribed, and the content of the discussions was systematically analyzed in 2 phases of coding by the research team, facilitated by Nvivo qualitative analysis software (QSR International, Doncaster, VIC, Australia). Patient focus group discussions about the meanings and connotations of multiple terms related to sexual function, especially interest, desire, and arousal. 5 groups included male participants and 5 included female participants. Participants characterized (sexual) interest as a cognitive phenomenon and a situational response to a specific person. Similarly, they characterized (sexual) desire as a situational person-specific experience with some support for it as a cognitive phenomenon but more support for it as a physical phenomenon. In contrast, participants characterized sexual arousal as a physical phenomenon occurring in response to physical or visual stimulation and not related to a specific person. These results can help us understand how laypeople are using and responding to these terms when they are used in clinical and research settings. Patient participants in these groups were diverse in age, gender, sexual orientation, and health, with the potential to voice diverse perspectives on sexual functioning; however, the sample was limited to a single city in the southeastern United States. The meanings of interest, desire, and arousal were

Religion, relationships and reproduction: correlates of desire for a child among mothers living with HIV.

De La Cruz, Natalie G; Davies, Susan L; Stewart, Katharine E

2011-08-01

Despite challenges facing HIV-positive women in the U.S., some maintain strong desires and intentions for motherhood. We explore correlates of desire for another child-particularly current parenting experiences (number of children, parenting efficacy, parenting satisfaction, parenting practices, parental distress, and child-related quality of life), age, spirituality/religiosity, stress, coping, hopelessness, partner's desire for a child, social support, and stigma-among a sample of HIV-positive mothers (n = 96) in Alabama. Partner's desire for a child, participation in private religious practices, avoidant coping, and parity were significantly associated with desire for a child in multivariate models. Such findings indicate a need for reproductive counseling and education that is sensitive to the role of religious norms and values in fertility decision-making and suggest opportunities for partnership with faith-based organizations. Further studies examining the impact of relationship dynamics on childbearing desires among U.S. women living with HIV/AIDS are also needed.

Full velocity difference car-following model considering desired inter-vehicle distance

Xin, Tong; Yi, Liu; Rongjun, Cheng; Hongxia, Ge

Based on the full velocity difference car-following model, an improved car-following model is put forward by considering the driver’s desired inter-vehicle distance. The stability conditions are obtained by applying the control method. The results of theoretical analysis are used to demonstrate the advantages of our model. Numerical simulations are used to show that traffic congestion can be improved as the desired inter-vehicle distance is considered in the full velocity difference car-following model.

Grewal, Gurdeep Singh; Gill, Jesjeet Singh; Sidi, Hatta; Gurpreet, Kaur; Jambunathan, Stephen Thevanathan; Suffee, Nusrat J

2013-04-01

The aim of this study was to determine the prevalence and risk factors for female sexual desire disorder (FSDD) among healthcare personnel at selected healthcare facilities in Malaysia. Two hundred and one female healthcare workers from three large tertiary hospitals were selected by stratified random sampling to participate in this cross-sectional study. Validated questionnaires were used to assess depression, anxiety, and sexual function in women and erectile dysfunction (ED) in their partners. The prevalence of FSDD was 18.9%. Women with low sexual desire were more likely to have higher educational attainment (OR = 3.06; 95% CI; 1.22-7.66), lower frequency of sexual intercourse (OR = 12.81; 95% CI; 4.43-37.83), two or more children (OR = 3.05; 95% CI; 1.02-9.09), duration of marriage of 20 years or more (OR = 2.62; 95% CI; 1.27-5.40), and a spouse with ED (OR = 2.86; 95% CI; 1.08-7.56). FSDD is common among female healthcare personnel in Malaysia, affecting nearly one in five women. The implication of low sexual desire is important in terms of contributing to a meaningful sexual relationship, and indirectly affects the quality of life of the healthcare personnel.

Renard, F. M.

Nous présentons I 'état du Modèle Standard des interactions fortes, faibles et électromagnétiques. Après une description rapide de ses 3 secteurs, secteur de jauge (radiation), secteur fermionique (matière) et secteur scalaire (génération des masses), nous insistons sur le grand nombre de paramètres libres et sur les choix arbitraires qu'il a fallu faire dans l'élaboration du modèle. Nous faisons ressortir les problèmes techniques non résolus et nous dressons la liste des questions fondamentales restées sans réponses. Nous passons ensuite en revue les idées et méthodes proposées pour répondre à ces questions. Elles utilisent essentiellement 3 voies différentes. La première consiste à requérir plus de symétrie (extension du modèle, symétrie Gauche-Droite, Grandes Unifications, Supersymétrie,...). La seconde contient les diverses alternatives au Modèle Standard impliquant des modifications dans certains secteurs (par exemple le secteur scalaire avec le modèle de la Technicouleur) ou de façon plus violente l'hypothèse d'une sous-structure des leptons, des quarks et des bosons W et Z eux-mêmes. Une dernière voie cherche à justifier les particularités du Modèle Standard et relier ses paramètres libres en se basant sur des principes de cohérence interne du modèle. Les conséquences observables de ces diverses approches sont dans chaque cas mentionnées.

LeCPK1, a Calcium-Dependent Protein Kinase from Tomato. Plasma Membrane Targeting and Biochemical Characterization1

2002-01-01

The cDNA of LeCPK1, a calcium-dependent protein kinase, was cloned from tomato (Lycopersicon esculentum Mill.). LeCPK1 was expressed in Escherichia coli and purified from bacterial extracts. The recombinant protein was shown to be a functional protein kinase using a synthetic peptide as the substrate (syntide-2, Km = 85 μm). Autophosphorylation of LeCPK1 was observed on threonine and serine residues, one of which was identified as serine-439. Kinase activity was shown to be Ca2+ dependent and required the C-terminal, calmodulin-like domain of LeCPK1. Two classes of high- and low-affinity Ca2+-binding sites were observed, exhibiting dissociation constants of 0.6 and 55 μm, respectively. LeCPK1 was found to phosphorylate the regulatory C-terminal domain of the plasma membrane H+-ATPase in vitro. A potential role in the regulation of proton pump activity is corroborated by the apparent colocalization of the plasma membrane H+-ATPase and LeCPK1 in vivo. Upon transient expression in suspension-cultured cells, a C-terminal fusion of LeCPK1 with the green fluorescent protein was targeted to the plasma membrane. Myristoylation of the LeCPK1 N terminus was found to be required for plasma membrane targeting. PMID:12011347

2006-01-01

To describe patients' perceptions of minimum worthwhile and desired reductions in pain and disability upon commencing treatment for chronic low back pain. Descriptive study nested within a community-based randomized controlled trial on prolotherapy injections and exercises. A total of 110 participants with chronic low back pain. Interventions. Prior to treatment, participants were asked what minimum percentage reductions in pain and disability would make treatment worthwhile and what percentage reductions in pain and disability they desired with treatment. Minimum worthwhile reductions and desired reductions in pain and disability. Median (inter-quartile range) minimum worthwhile reductions were 25% (20%, 50%) for pain and 35% (20%, 50%) for disability. This compared with desired reductions of 80% (60%, 100%) for pain and 80% (50%, 100%) for disability. The internal consistency between pain and disability responses was high (Spearman's coefficient of association of 0.81 and 0.87, respectively). A significant association existed between minimum worthwhile reductions and desired reductions, but no association was found between these two factors and patient age, gender, pain severity or duration, disability, anxiety, depression, response to treatment, or treatment satisfaction. Inquiring directly about patients' expectations of reductions in pain and in disability is important in establishing realistic treatment goals and setting benchmarks for success. There is a wide disparity between the reductions that they regard as minimum worthwhile and reductions that they hope to achieve. However, there is a high internal consistency between reductions in pain and disability that they expect.

Introduction Le défi des pays en voie de développement est la disponibilité de méthodes de diagnostic rapide et précis pour le management de la tuberculose. Des techniques moléculaires offrent cet avantage et nous avons utilisé le test GeneXpert MTB/RIF dans le diagnostic de la tuberculose extra-pulmonaire pour évaluer sa performance par rapport aux méthodes conventionnelles. Méthodes Entre 2010 et 2015, 544 échantillons cliniques extra-pulmonaires ont été recueillis et traitées par la microscopie, la culture et le GeneXpert. L'étude de la sensibilité aux antituberculeux a été effectué avec le MGIT 960. Le Génotype MTBDRplus a été utilisé pour confirmer les cas de résistance à la rifampicine détectés par le système GX. Résultats La population d'étude de 544 patients incluait 55,15% d'hommes et 44,85% de femmes. L'âge des patients variait entre 1 à 92 avec la majorité dans le groupe d'âge 18-45 ans. La sensibilité et la spécificité globale de la microscopie étaient de 43,86% et 98,36%, et pour le GeneXpert® 94,74% et 97,95% respectivement avec 95% IC. Deux résultats de résistance à la rifampicine discordants ont été trouvées entre le test GeneXpert et la méthode phénotypique. Les résultats du test MTBDRplus ont montré une concordance de 100% avec ceux du MGIT 960 pour les cas discordants de résistance à la rifampicine. Conclusion Cette étude a montré que le test GeneXpert a une plus grande sensibilité pour le diagnostic de routine de la tuberculose extra-pulmonaire et devrait être utilisé à la place de la microscopie. Les cas de résistance à la rifampicine détectés par le GeneXpert doivent être confirmés par d'autres tests moléculaires avant d'initier un traitement. PMID:28292091

To determine the prevalence of hypoactive sexual desire dysfunction (HSDD) and its associated factors in women aged 65 to 79 years. A questionnaire-based, cross-sectional study was conducted amongst community-dwelling older women. Participants were recruited between April and August 2014 from a national database based on electoral rolls. Sexual function and sexual distress were assessed by the Female Sexual Function Index and the Female Sexual Distress Scale-Revised, respectively. HSDD was defined as the presence of both low sexual desire and sexually related personal distress. The mean ± SD age of the 1,548 women was 71 ± 3.4 years and 52.6% were partnered. Among the participants, 88.0% (95% confidence interval [CI], 86.3%-89.6%) had low sexual desire, 15.5% (95% CI, 13.8%-17.4%) had sexually related personal distress, and 13.6% (95% CI, 11.9%-15.4%) had HSDD. The HSDD was more common among partnered than among unpartnered women (23.7% vs 5.9%; P < 0.001). Being partnered (adjusted odds ratio [AOR] = 4.21; 95% CI, 2.50-7.07), having vaginal dryness during intercourse (AOR = 2.37; 95% CI, 1.58-3.55), having symptomatic pelvic floor dysfunction (AOR = 1.92; 95% CI, 1.29-2.92), and having moderate-to-severe depressive symptoms (AOR = 4.15; 95% CI, 2.16-7.96) were independently associated with having HSDD. In a subanalysis, HSDD was more common among sexually active than sexually inactive women (31.5% vs 17.3%; P < 0.001). Furthermore, 32% (95% CI, 27.7%-38.3%) of partnered sexually active women had HSDD, as did 22% (95% CI, 11.5%-37.8%) of unpartnered sexually active women. HSDD is common and associated with potentially modifiable risk factors in older women. It should not be assumed that unpartnered older women are sexually inactive or are not distressed by low sexual desire.

LE135, a retinoid acid receptor antagonist, produces pain through direct activation of TRP channels

PubMed Central

Yin, Shijin; Luo, Jialie; Qian, Aihua; Yu, Weihua; Hu, Hongzhen

2014-01-01

Background and PurposeRetinoids, through their activation of retinoic acid receptors (RARs) and retinoid X receptors, regulate diverse cellular processes, and pharmacological intervention in their actions has been successful in the treatment of skin disorders and cancers. Despite the many beneficial effects, administration of retinoids causes irritating side effects with unknown mechanisms. Here, we demonstrate that LE135 [4-(7,8,9,10-tetrahydro-5,7,7,10,10-pentamethyl-5H-benzo[e]naphtho[2,3-b][1,4]diazepin-13-yl)benzoic acid], a selective antagonist of RARβ, is a potent activator of the capsaicin (TRPV1) and wasabi (TRPA1) receptors, two critical pain-initiating cation channels. Experimental ApproachWe performed to investigate the excitatory effects of LE135 on TRPV1 and TRPA1 channels expressed in HEK293T cells and in dorsal root ganglia neurons with calcium imaging and patch-clamp recordings. We also used site-directed mutagenesis of the channels to determine the structural basis of LE135-induced activation of TRPV1 and TRPA1 channels and behavioural testing to examine if pharmacological inhibition and genetic deletion of the channels affected LE135-evoked pain-related behaviours. Key ResultsLE135 activated both the capsaicin receptor (TRPV1) and the allyl isothiocyanate receptor (TRPA1) heterologously expressed in HEK293T cells and endogenously expressed by sensory nociceptors. Mutations disrupting the capsaicin-binding site attenuated LE135 activation of TRPV1 channels and a single mutation (K170R) eliminated TRPA1 activity evoked by LE135. Intraplantar injection of LE135 evoked pain-related behaviours. Both TRPV1 and TRPA1 channels were involved in LE135-elicited pain-related responses, as shown by pharmacological and genetic ablation studies. Conclusions and ImplicationsThis blocker of retinoid acid signalling also exerted non-genomic effects through activating the pain-initiating TRPV1 and TRPA1 channels. PMID:24308840

Concordance between partners in desired waiting time to birth for newlyweds in India

PubMed Central

Singh, Abhishek; Becker, Stan

2014-01-01

Examining waiting time to birth among newlywed couples is likely to provide insights into the desire for spacing births among newlywed husbands and wives. Data from the Indian National Family Health Survey of 2005-06 is used to examine the desired waiting time (DWT) to birth among newlywed couples. The dependent variable is spousal concordance on desired times. Overall 65 % of couples have concordant DWTs. Among discordant couples, wives were more likely to want to wait longer than their husbands. Couples from richer wealth quintiles were more likely than couples from poorest quintile to have a concordant DWTs. Muslims were less likely than Hindus to have concordant desires. There is a need for spacing methods among newlyweds. This may have implications for the Indian Family Planning Programme which to date has largely focused on sterilization. Programmes need to include newlywed husbands to promote use of spacing methods. PMID:21933466

Clinical and theoretical parallels between desire for limb amputation and gender identity disorder.

PubMed

Lawrence, Anne A

2006-06-01

Desire for amputation of a healthy limb has usually been regarded as a paraphilia (apotemnophilia), but some researchers propose that it may be a disorder of identity, similar to Gender Identity Disorder (GID) or transsexualism. Similarities between the desire for limb amputation and nonhomosexual male-to-female (MtF) transsexualism include profound dissatisfaction with embodiment, related paraphilias from which the conditions plausibly derive (apotemnophilia and autogynephilia), sexual arousal from simulation of the sought-after status (pretending to be an amputee and transvestism), attraction to persons with the same body type one wants to acquire, and an elevated prevalence of other paraphilic interests. K. Freund and R. Blanchard (1993) proposed that nonhomosexual MtF transsexualism represents an erotic target location error, in which men whose preferred erotic targets are women also eroticize their own feminized bodies. Desire for limb amputation may also reflect an erotic target location error, occurring in combination with an unusual erotic target preference for amputees. This model predicts that persons who desire limb amputation would almost always be attracted to amputees and would display an increased prevalence of gender identity problems, both of which have been observed. Persons who desire limb amputation and nonhomosexual MtF transsexuals often assert that their motives for wanting to change their bodies reflect issues of identity rather than sexuality, but because erotic/romantic orientations contribute significantly to identity, such distinctions may not be meaningful. Experience with nonhomosexual MtF transsexualism suggests possible directions for research and treatment for persons who desire limb amputation.

Focusing light into desired patterns through turbid media by feedback-based wavefront shaping

NASA Astrophysics Data System (ADS)

Wan, Lipeng; Chen, Ziyang; Huang, Huiling; Pu, Jixiong

2016-07-01

We demonstrate that the focusing of light into desired patterns through turbid media can be realized using feedback-based wavefront shaping. Three desired focused patterns—a triangle, a circle, and a rectangle—are used as examples to study this ability. During the process of modulating scattered light, the Pearson's correlation coefficient is introduced as a feedback signal. It is found that the speckle field formed by the turbid media gradually transforms into the desired pattern through a process of modulation of the input beam wave front. The proposed approach has potential applications in biomedical treatment and laser material processing.

Le mariage est un évènement très investi dans notre culture arabo-musulmane. Il présente une situation à grande charge émotionnelle et ayant un vécu stressant. C'est ainsi qu'il peut être à l'origine de la décompensation de certains troubles psychiatriques. Ce moment particulier de déclenchement de la pathologie peut altérer significativement l'adaptation familiale et sociale du patient en question, le rendant dépendant en partie ou en totalité à une institution. Dans ce travail, nous proposons d’étudier certains facteurs psychiques, sociaux et culturels pouvant aboutir à la précipitation des manifestations psychotiques par le mariage. Il s'agit de l’étude de trois observations cliniques, deux hommes et une femme, hospitalisés dans le service de psychiatrie A du CHU Hédi Chaker de Sfax et qui ont développés des manifestations psychotiques de façon concomitante à leur mariage. La durée moyenne de survenue des crises a été de vingt ans, le diagnostic retenu a été celui de trouble bipolaire dans deux cas et d'une schizophrénie indifférenciée chez le troisième patient. L’évolution s'est faite vers une chronicisation de deux malades et une dépendance institutionnelle dans le troisième cas. La précipitation des troubles psychotiques par le mariage, reste un phénomène en relation intime avec les composantes culturelles, elles-mêmes sont déterminantes dans la prise en charge ultérieure de ces patients.

1993-06-01

A qualitative and quantitative analysis of airborne pollen and spores was carried out over 2 years (from September 1987 to August 1989) in the city of León. Slides were prepared daily using a volumetric pollen trap, which was placed on the Faculty of Veterinary Science building (University of León) 12m above ground-level. Fifty-one pollen types were observed; the most important of these were: Cupressaceae during the winter, Pinus and Quercus in spring, and Poaceae, Leguminosae and Chenopodiaceae in the summer. The results also showed the existence of a rich mould spore assemblage in the atmosphere. The group of Amerospores ( Penicillium, Aspergillus and Cladosporium) as well as Dictyospores ( Alternaria) were the most abundant; Puccinia was common in the air in August. Fluctuations in the total pollen and spores m3 of air were compared with meteorological parameters (temperature, relative humidity and rainfall). From the daily sampling of the atmosphere of León, considering the maximum and minimum temperature and duration of rainfall, the start of the pollen grain season was observed generally to coincide with a rise in temperature in the absence of rain.

To assess the impact of RP on patients' sexual desire and orgasm. Prospective, cross-sectional survey using a 16-item self-administered questionnaire. We assessed relevant domains of male sexual function (erectile function, sexual desire, and orgasm), psychological impact and treatment of ED. A total of 63 consecutive patients after RP were included (mean age: 63.9). Median time between questionnaire and RP was 26.8 months (range 6-67). After RP, 74.6 % of patients used ED treatments. Lower sexual desire and intercourse frequency were reported in respectively 52.4 and 79.4 %. Orgasm was modified in most patients: 39.7 % described loss of orgasm and 38.1 % reported decreased intensity. Involuntary loss of urine at orgasm (climacturia) was reported in 25.4 %. Negative psychological impact was reported in 68.3 % (loss of self-esteem, loss of masculinity, anxiety). RP adversely affected erectile and orgasmic functions but also sexual desire, self-esteem and masculinity despite treatments. Candidates for RP should be aware of ED but also of other postoperative sexual dysfunctions. 2010 Elsevier Masson SAS. All rights reserved.

Comparing continuous and dichotomous scoring of the balanced inventory of desirable responding.

Stöber, Joachim; Dette, Dorothea E; Musch, Jochen

2002-04-01

The Balanced Inventory of Desirable Responding (BIDR; Paulhus, 1994) is a widely used instrument to measure the 2 components of social desirability: self-deceptive enhancement and impression management. With respect to scoring of the BIDR, Paulhus (1994) authorized 2 methods, namely continuous scoring (all answers on the continuous answer scale are counted) and dichotomous scoring (only extreme answers are counted). In this article, we report 3 studies with student samples, and continuous and dichotomous scoring of BIDR subscales are compared with respect to reliability, convergent validity, sensitivity to instructional variations, and correlations with personality. Across studies, the scores from continuous scoring (continuous scores) showed higher Cronbach's alphas than those from dichotomous scoring (dichotomous scores). Moreover, continuous scores showed higher convergent correlations with other measures of social desirability and more consistent effects with self-presentation instructions (fake-good vs. fake-bad instructions). Finally, continuous self-deceptive enhancement scores showed higher correlations with those traits of the Five-factor model for which substantial correlations were expected (i.e., Neuroticism, Extraversion, and Conscientiousness). Consequently, these findings indicate that continuous scoring may be preferable to dichotomous scoring when assessing socially desirable responding with the BIDR.

Le syndrome de Currarino (SC) est défini par une triade rassemblant une malformation ano-rectale, une agénésie sacrée et une tumeur pré-sacrée. Nous rapportons le cas d'une fille de 4 ans et demi ayant été admise en consultation de gastro-entérologie pédiatrique pour constipation avec issue de selle à travers un orifice vulvaire. La radiographie du rachis avait montré une agénésie sacrée. Le fistulo-scanner a mis en évidence une fistule recto-vaginale et l'IRM pelvienne a confirmé l'agénésie sacrée et a retrouvé une méningocèle antérieure. La découverte d'une malformation ano-rectale doit faire chercher une autre anomalie de la triade de Currarino. Cette affection, rare, nécessite une prise en charge médico-chirurgicale assez complexe.

This study was conducted to test interpersonal, attitudinal, and sexual predictors of sexual assertiveness in a Spanish sample of 1,619 men and 1,755 women aged 18-87 years. Participants completed measures of sexual assertiveness, solitary and dyadic sexual desire, sexual arousal, erectile function, sexual attitudes, and frequency of partner abuse. In men, higher sexual assertiveness was predicted by less non-physical abuse, more positive attitudes toward sexual fantasies and erotophilia, higher dyadic desire, and higher sexual arousal. In women, higher sexual assertiveness was predicted by less non-physical abuse, less solitary sexual desire and higher dyadic sexual desire, arousal, erotophilia, and positive attitudes towards sexual fantasies. Results were discussed in the light of prevention and educational programs that include training in sexual assertiveness skills.

Le syndrome d'Ekbom, ou délire d'infestation parasitaire, est une pathologie rare, caractérisée par la conviction inébranlable d'avoir une peau infestée d'insectes ou de parasites. Il s'agit d'un délire monothématique à mécanisme hallucinatoire qui touche typiquement les femmes d’âge avancé. Nous rapportons les cas de trois patients qui présentent un délire d'infestation parasitaire dans des contextes cliniques différents. Le premier patient souffre d'un délire d'infestation isolé correspondant à la forme décrite par Karl Ekbom. Le deuxième cas présente un délire d'infestation secondaire, s'inscrivant dans le cadre d'une leuco-encéphalopathie de type CADASIL. Enfin, le troisième patient se présente dans un tableau évocateur d'un épisode dépressif avec une caractéristique psychotique qui intègre le délire d'infestation. Ces trois vignettes cliniques illustrent parfaitement le caractère trans-nosographique de ce syndrome ainsi que les difficultés de prise en charge de ces patients, tant au niveau de l'alliance thérapeutique que sur le plan des choix en matière de traitement pharmacologiques.

Correlational research investigating the relationship between scores on self-report imagery questionnaires and measures of social desirable responding has shown only a weak association. However, researchers have argued that this research may have underestimated the size of the relationship because it relied primarily on the Marlowe-Crowne scale (MC; Crowne & Marlowe, Journal of Consulting Psychology, 24, 349-354, 1960), which loads primarily on the least relevant form of social desirable responding for this particular context, the moralistic bias. Here we report the analysis of data correlating the Vividness of Visual Imagery Questionnaire (VVIQ; Marks, Journal of Mental Imagery, 19, 153-166, 1973) with the Balanced Inventory of Desirable Responding (BIDR; Paulhus, 2002) and the MC scale under anonymous testing conditions. The VVIQ correlated significantly with the Self-Deceptive Enhancement (SDE) and Agency Management (AM) BIDR subscales and with the MC. The largest correlation was with SDE. The ability of SDE to predict VVIQ scores was not significantly enhanced by adding either AM or MC. Correlations between the VVIQ and BIDR egoistic scales were larger when the BIDR was continuously rather than dichotomously scored. This analysis indicates that the relationship between self-reported imagery and social desirable responding is likely to be stronger than previously thought.

Seduction, prostitution, and the control of female desire in popular Antebellum fiction.

PubMed

Renner, Karen J

2010-01-01

During the antebellum era, increased attention to the prostitute coincided with a prevalent conception of women as, in Nancy Cott's words, essentially "passionless" unless aroused by sincere romantic love. Yet it seems paradoxical that this ideology existed alongside an increasing awareness of women whose livelihood depended upon manufacturing and marketing sexual desire. In this essay I argue that the prostitute became an object of antebellum fascination and concern less because of her defiance of the ideology of passionlessness and more because of the extent to which she could be made to reinforce this ideology. Casting the prostitute as a victim of seduction preserved predominant beliefs about the dependency of female desire on male impetus. The popular novels of George Thompson and Osgood Bradbury elide the sexual autonomy of the prostitute by making her a victim of men, but they do so in different ways. Thompson employs two variants of the seduction narrative that differ according to class, but both result in the subjection of female desire to male control. His indigent females are chaste victims of violent forms of sexual exploitation, while his licentious rich women reveal an inherent tendency toward monogamy or an inability to command their own aberrant desires. Bradbury, in contrast, is remarkable for his willingness to allow fallen women and prostitutes the chance to reform. As refreshingly progressive as Bradbury's novels seem, however, his adherence to the seduction narrative ultimately suggests that female desire is doomed to dissatisfaction unless properly channeled toward working-class men.

Empathic Concern and the Desire to Help as Separable Components of Compassionate Responding.

2018-04-01

When do people experience versus regulate responses to compassion-evoking stimuli? We hypothesized that compassionate responding is composed of two factors-empathic concern and the desire to help-and that these would be differentially affected by perspective taking and self-affirmation. Exploratory (Study 1) and confirmatory (Study 2) factor analyses indicated that a compassion measure consisted of two factors corresponding to empathic concern and the desire to help. In Study 1 ( N = 237), participants with high emotion regulation ability reported less empathic concern for multiple children than for one, but perspective taking prevented this effect. In Study 2 ( N = 155), participants reported less desire to help multiple children, but only in the presence of self-affirmation. In both the studies, empathic concern predicted greater distress while the desire to help predicted greater chances of donating. Compassionate responding may consist of two separable facets that collapse under distinct conditions and that predict distinct outcomes.

Dosch, Alessandra; Rochat, Lucien; Ghisletta, Paolo; Favez, Nicolas; Van der Linden, Martial

2016-11-01

This study explored the role of psychological trait factors in sexual desire and sexual activity. In particular, it investigated how these factors may contribute to maintaining a balance between motivational aspects and self-control abilities, as both have been considered important in relation to adaptive sexuality. Moreover, the study explored the relationship between sexual desire, activity, and satisfaction. Participants completed questionnaires assessing sexual desire (dyadic, solitary), sexual activity (with a partner, alone), sexual satisfaction, approach and avoidance motivation, attachment, self-control, sensation seeking, and mindfulness. Cluster analyses, based on participants' level of sexual desire and sexual activity, highlighted three distinct profiles for each gender related to different types of psychological functioning: (a) participants with high dyadic sexual desire and activity were the most sexually satisfied, showed optimal psychological functioning, and were characterized by a balance between motivational tendencies to seek positive rewards and self-control abilities (high approach motivation, secure attachment, high self-control, high mindfulness); (b) participants with high dyadic and solitary sexual desire and activity were moderately satisfied and showed a type of psychological functioning predominantly characterized by impulsivity (an overly high motivation to obtain rewards in women, and low self-control in men); (c) participants with low dyadic sexual desire and activity were the least sexually satisfied and were characterized by high motivation to avoid negative consequences and low self-control (high avoidance motivation, insecure attachment, and poor mindfulness). These results shed further light on how fundamental psychological factors contribute to explain the individual variability in sexual desire, activity, and satisfaction.

Abstract Background Unintended pregnancy has been significantly associated with subsequent female sterilization. Whether women who are sterilized after experiencing an unintended pregnancy are less likely to express desire for sterilization reversal is unknown. Methods This study used national, cross-sectional data collected by the 2006–2010 National Survey of Family Growth. The study sample included women ages 15–44 who were surgically sterile from a tubal sterilization at the time of interview. Multivariable logistic regression was used to examine the relationship between a history of unintended pregnancy and desire for sterilization reversal while controlling for potential confounders. Results In this nationally representative sample of 1,418 women who were sterile from a tubal sterilization, 78% had a history of at least one unintended pregnancy and 28% expressed a desire to have their sterilization reversed. In unadjusted analysis, having a prior unintended pregnancy was associated with higher odds of expressing desire for sterilization reversal (odds ratio [OR]: 1.80; 95% confidence interval [CI]: 1.15–2.79). In adjusted analysis controlling for sociodemographic factors, unintended pregnancy was no longer significantly associated with desire for reversal (OR: 1.46; 95% CI: 0.91–2.34). Conclusion Among women who had undergone tubal sterilization, a prior history of unintended pregnancy did not decrease desire for sterilization reversal. PMID:23621776

Summary Les Auteurs décrivent le cas d’un patient âgé de 45 ans atteint de brûlures thermiques par flammes suite à la déflagration d’une bonbonne de gaz. Les lésions initiales intéressaient les quatre membres (en particulier, le genou) et le tronc. La prise en charge initiale a consisté en une excision-greffe précoce des membres. L’évolution a été marquée par la survenue de cicatrices hypertrophiques au niveau des zones non greffées et à la bordure de la greffe ainsi que la survenue de brides rétractiles. Devant l’handicap fonctionnel engendré par la bride à cause de la limitation importante de l’extension, le patient a été admis pour cure chirurgicale. Grâce à la technique en rail décrite, le patient a pu récupérer une fonction normale du genou. Les suites ont été simples avec une durée d’hospitalisation d’un mois. Le résultat esthétique est relativement satisfaisant. La technique en rail est un moyen parmi l’arsenal thérapeutique qui permet de traiter la bride du creux poplité. Sa simplicité, sa facilité technique et son résultat satisfaisant ainsi que ses suites simples permettent de la rendre une technique très prisée dans le traitement de ce type de bride. PMID:21991240

Crystallization of desire and crystallization of discontent in narratives of life-changing decisions.

PubMed

Bauer, Jack J; McAdams, Dan P; Sakaeda, April R

2005-10-01

Two studies of adults examined personal narratives of life-changing decisions in relation to personality and well-being. Participants whose decision narratives emphasized a crystallization of desire (i.e., approaching a desired future) rather than a crystallization of discontent (i.e., escaping an undesired past; Baumeister, 1991, 1994) reported higher well-being, fewer avoidance strivings, lower Neuroticism (in Study 1 only), and better decision outcomes (in Study 2). However, neither strivings, traits, nor outcomes accounted for the relationship between crystallization of desire and well-being. The discussion considers the roles of life-changing decisions and personal narratives in research on personality, well-being, and positive personal development.

Social desirability is sometimes associated with poor prognosis in cancer patients. Psycho-neuro-immune interaction has been hypothesized as an underlying mechanism of the negative clinical outcome. Purpose of this study was to examine possible effects of high social desirability on the regional brain activity in patients with malignant diseases. Brain metabolism of 16 patients with various malignant diseases was measured by PET with 18F-fluorodeoxyglucose (FDG). Patients were divided into 2 groups using median split on Marlowe & Crown's Social Desirability Scale (MC), controlling for age, gender, and for severity of depression and anxiety, the possible two major influential factors. A group comparison of the regional cerebral activity was calculated on a voxel-by-voxel basis using statistical parametric mapping (SPM). The subgroup comparison showed that the high social desirability was associated with relatively increased metabolism in the cortical regions in the prefrontal, temporal and occipital lobes as well as in the anterior cingulate gyrus. High social desirability seems to be associated with increased activity in the prefrontal and other cortical areas. The finding is in an accordance with previous studies that demonstrated an association between prefrontal damage and anti-social behavior. Functional neuroimaging seems to be useful not only for psychiatric evaluation of major factors such as depression and anxiety but also for further psychosocial factors in cancer patients.

One of the most difficult dilemmas in relationship science and couple therapy concerns the interaction between sexual desire and love. As two mental states of intense longing for union with others, sexual desire and love are, in fact, often difficult to disentangle from one another. The present review aims to help understand the differences and similarities between these two mental states using a comprehensive statistical meta-analyses of all functional magnetic resonance imaging (fMRI) studies on sexual desire and love. Systematic retrospective review of pertinent neuroimaging literature. Review of published literature on fMRI studies illustrating brain regions associated with love and sexual desire to date. Sexual desire and love not only show differences but also recruit a striking common set of brain areas that mediate somatosensory integration, reward expectation, and social cognition. More precisely, a significant posterior-to-anterior insular pattern appears to track sexual desire and love progressively. This specific pattern of activation suggests that love builds upon a neural circuit for emotions and pleasure, adding regions associated with reward expectancy, habit formation, and feature detection. In particular, the shared activation within the insula, with a posterior-to-anterior pattern, from desire to love, suggests that love grows out of and is a more abstract representation of the pleasant sensorimotor experiences that characterize desire. From these results, one may consider desire and love on a spectrum that evolves from integrative representations of affective visceral sensations to an ultimate representation of feelings incorporating mechanisms of reward expectancy and habit learning. © 2012 International Society for Sexual Medicine.

Despite the development of multi-drug regimens for HIV, palliative care and quality-of-life issues in patients with advanced AIDS remain important areas of clinical investigation. Authors assessed the impact of treatment for depression on desire for hastened death in patients with advanced AIDS. Patients with advanced AIDS (N=372) were interviewed shortly after admission to a palliative-care facility, and were reinterviewed monthly for the next 2 months. Patients diagnosed with a major depressive syndrome were provided with antidepressant treatment and reinterviewed weekly. Desire for hastened death was assessed with two questionnaire measures. Desire for death was highly associated with depression, and it decreased dramatically in patients who responded to antidepressant treatment. Little change in desire for hastened death was observed in patients whose depression did not improve. Although improved depression was not significantly associated with the use of antidepressant medication, those individuals prescribed antidepressant medication showed the largest decreases in desire for hastened death. Successful treatment for depression appears to substantially decrease desire for hastened death in patients with advanced AIDS. The authors discuss implications of these findings for palliative-care treatment and the physician-assisted suicide debate.

Etude thermo-hydraulique de l'ecoulement du moderateur dans le reacteur CANDU-6

Mehdi Zadeh, Foad

Etant donne la taille (6,0 m x 7,6 m) ainsi que le domaine multiplement connexe qui caracterisent la cuve des reacteurs CANDU-6 (380 canaux dans la cuve), la physique qui gouverne le comportement du fluide moderateur est encore mal connue de nos jours. L'echantillonnage de donnees dans un reacteur en fonction necessite d'apporter des changements a la configuration de la cuve du reacteur afin d'y inserer des sondes. De plus, la presence d'une zone intense de radiations empeche l'utilisation des capteurs courants d'echantillonnage. En consequence, l'ecoulement du moderateur doit necessairement etre etudie a l'aide d'un modele experimental ou d'un modele numerique. Pour ce qui est du modele experimental, la fabrication et la mise en fonction de telles installations coutent tres cher. De plus, les parametres de la mise a l'echelle du systeme pour fabriquer un modele experimental a l'echelle reduite sont en contradiction. En consequence, la modelisation numerique reste une alternative importante. Actuellement, l'industrie nucleaire utilise une approche numerique, dite de milieu poreux, qui approxime le domaine par un milieu continu ou le reseau des tubes est remplace par des resistances hydrauliques distribuees. Ce modele est capable de decrire les phenomenes macroscopiques de l'ecoulement, mais ne tient pas compte des effets locaux ayant un impact sur l'ecoulement global, tel que les distributions de temperatures et de vitesses a proximite des tubes ainsi que des instabilites hydrodynamiques. Dans le contexte de la surete nucleaire, on s'interesse aux effets locaux autour des tubes de calandre. En effet, des simulations faites par cette approche predisent que l'ecoulement peut prendre plusieurs configurations hydrodynamiques dont, pour certaines, l'ecoulement montre un comportement asymetrique au sein de la cuve. Ceci peut provoquer une ebullition du moderateur sur la paroi des canaux. Dans de telles conditions, le coefficient de reactivite peut varier de maniere

Le moulage par injection basse pression des poudres metalliques est une technique de fabrication qui permet de fabriquer des pieces possedant la complexite des pieces coulees mais avec les proprietes mecaniques des pieces corroyees. Cependant, l'optimisation des etapes de deliantage et de frittage a ete jusqu'a maintenant effectuee a l'aide de melange pour lesquels la moulabilite optimale n'a pas encore ete demontree. Ainsi, la comprehension des proprietes rheologiques et de la segregation des melanges est tres limitee et cela presente le point faible du processus de LPIM. L'objectif de ce projet de recherche etait de caracteriser l'influence des liants sur le comportement rheologique des melanges en mesurant la viscosite et la segregation des melanges faible viscosite utilises dans le procede LPIM. Afin d'atteindre cet objectif, des essais rheologiques et thermogravimetriques ont ete conduits sur 12 melanges. Ces melanges ont ete prepares a base de poudre d'Inconel 718 de forme spherique (chargement solide constant a 60%) et de cires, d'agents surfactants ou epaississants. Les essais rheologiques ont ete utilises entre autre pour calculer l'indice d'injectabilite ?STV des melanges, tandis que les essais thermogravimetriques ont permis d'evaluer precisement la segregation des poudres dans les melanges. Il a ete demontre que les trois (3) melanges contenant de la cire de paraffine et de l'acide stearique presentent des indices alpha STV plus eleves qui sont avantageux pour le moulage par injection des poudres metalliques (MIM), mais segregent beaucoup trop pour que la piece fabriquee produise de bonnes caracteristiques mecaniques. A l'oppose, le melange contenant de la cire de paraffine et de l'ethylene-vinyle acetate ainsi que le melange contenant seulement de la cire de carnauba segregent peu voire pas du tout, mais possedent de tres faibles indices alphaSTV : ils sont donc difficilement injectables. Le meilleur compromis semble donc etre les melanges contenant de

The desired moral attitude of the physician: (II) compassion.

PubMed

Gelhaus, Petra

2012-11-01

Professional medical ethics demands of health care professionals in addition to specific duties and rules of conduct that they embody a responsible and trustworthy personality. In the public discussion, different concepts are suggested to describe the desired implied attitude of physicians. In a sequel of three articles, a set of three of these concepts is presented in an interpretation that is meant to characterise the morally emotional part of this attitude: "empathy", "compassion" and "care". In the first article of the series, "empathy" has been developed as a mainly cognitive and morally neutral capacity of understanding. In this article, the emotional and virtuous core of the desired professional attitude-compassion-is elaborated. Compassion is distinguished from sympathy, empathy and pity. Several problems of compassion as a spontaneous, warm emotion for being a professional virtue are discussed: especially questions of over-demand, of justice and of concerns because of a possible threat to the patient's dignity and autonomy. An interpretation of compassion as processed and learned professional attitude, that founds dignity on the general idea of man as a sentient being and on solidarity, not on his independence and capacities, is developed. It is meant to rule out the possible side effects and to make compassion as a professional attitude and as professional virtue attractive, teachable and acquirable. In order to reach the adequate warmth and closeness for the particular physician-patient-relation, professional compassion has to be combined with the capacity of empathy. If appropriate, the combination of both empathy and compassion as "empathic compassion" can demand a much warmer attitude towards the patient than each of the elements alone, or the simple addition of them can provide. The concept of "care" that will be discussed in a forthcoming article of this sequel is a missing necessary part to describe the active potential of the desired moral

Social desirability bias in dietary self-report may compromise the validity of dietary intake measures.

Self-report of dietary intake could be biased by social desirability or social approval thus affecting risk estimates in epidemiological studies. These constructs produce response set biases, which are evident when testing in domains characterized by easily recognizable correct or desirable responses. Given the social and psychological value ascribed to diet, assessment methodologies used most commonly in epidemiological studies are particularly vulnerable to these biases. Social desirability and social approval biases were tested by comparing nutrient scores derived from multiple 24-hour diet recalls (24HR) on seven randomly assigned days with those from two 7-day diet recalls (7DDR) (similar in some respects to commonly used food frequency questionnaires), one administered at the beginning of the test period (pre) and one at the end (post). Statistical analysis included correlation and multiple linear regression. Cross-sectionally, no relationships between social approval score and the nutritional variables existed. Social desirability score was negatively correlated with most nutritional variables. In linear regression analysis, social desirability score produced a large downward bias in nutrient estimation in the 7DDR relative to the 24HR. For total energy, this bias equalled about 50 kcal/point on the social desirability scale or about 450 kcal over its interquartile range. The bias was approximately twice as large for women as for men and only about half as large in the post measures. Individuals having the highest 24HR-derived fat and total energy intake scores had the largest downward bias due to social desirability. We observed a large downward bias in reporting food intake related to social desirability score. These results are consistent with the theoretical constructs on which the hypothesis is based. The effect of social desirability bias is discussed in terms of its influence on epidemiological estimates of effect. Suggestions are made for future work

Human punishment is motivated by inequity aversion, not a desire for reciprocity.

PubMed

Raihani, N J; McAuliffe, K

2012-10-23

Humans involved in cooperative interactions willingly pay a cost to punish cheats. However, the proximate motives underpinning punitive behaviour are currently debated. Individuals who interact with cheats experience losses, but they also experience lower payoffs than the cheating partner. Thus, the negative emotions that trigger punishment may stem from a desire to reciprocate losses or from inequity aversion. Previous studies have not disentangled these possibilities. Here, we use an experimental approach to ask whether punishment is motivated by inequity aversion or by a desire for reciprocity. We show that humans punish cheats only when cheating produces disadvantageous inequity, while there is no evidence for reciprocity. This finding challenges the notion that punishment is motivated by a simple desire to reciprocally harm cheats and shows that victims compare their own payoffs with those of partners when making punishment decisions.

Is Romantic Desire Predictable? Machine Learning Applied to Initial Romantic Attraction.

PubMed

Joel, Samantha; Eastwick, Paul W; Finkel, Eli J

2017-10-01

Matchmaking companies and theoretical perspectives on close relationships suggest that initial attraction is, to some extent, a product of two people's self-reported traits and preferences. We used machine learning to test how well such measures predict people's overall tendencies to romantically desire other people (actor variance) and to be desired by other people (partner variance), as well as people's desire for specific partners above and beyond actor and partner variance (relationship variance). In two speed-dating studies, romantically unattached individuals completed more than 100 self-report measures about traits and preferences that past researchers have identified as being relevant to mate selection. Each participant met each opposite-sex participant attending a speed-dating event for a 4-min speed date. Random forests models predicted 4% to 18% of actor variance and 7% to 27% of partner variance; crucially, however, they were unable to predict relationship variance using any combination of traits and preferences reported before the dates. These results suggest that compatibility elements of human mating are challenging to predict before two people meet.

Paying for performance: Performance incentives increase desire for the reward object.

PubMed

Hur, Julia D; Nordgren, Loran F

2016-09-01

The current research examines how exposure to performance incentives affects one's desire for the reward object. We hypothesized that the flexible nature of performance incentives creates an attentional fixation on the reward object (e.g., money), which leads people to become more desirous of the rewards. Results from 5 laboratory experiments and 1 large-scale field study provide support for this prediction. When performance was incentivized with monetary rewards, participants reported being more desirous of money (Study 1), put in more effort to earn additional money in an ensuing task (Study 2), and were less willing to donate money to charity (Study 4). We replicated the result with nonmonetary rewards (Study 5). We also found that performance incentives increased attention to the reward object during the task, which in part explains the observed effects (Study 6). A large-scale field study replicated these findings in a real-world setting (Study 7). One laboratory experiment failed to replicate (Study 3).

The Jackson Career Explorer: Correlates With Self-Monitoring and Social Desirability.

PubMed

Schermer, Julie Aitken

2018-01-01

The Jackson Career Explorer (JCE) is a short form and continuous version of the Jackson Vocational Interest Survey measuring 34 vocational interest dimensions which can be reduced to seven factors (six vocational interest factors and one work style factor). Both the scales and factors were examined for possible significant correlations with social desirability and self-monitoring. Volunteer participants ( N = 779) aged 14 to 92 years completed the JCE, a social desirability scale, and a self-monitoring scale. Social desirability did not correlate significantly with the JCE scales and factors. Self-monitoring was found to correlate significantly with only a few of the JCE dimensions, including the performing arts, dominant leadership, and law scales as well as the business factor. Interestingly, the accountability JCE work style scale, which assesses a preference to work in an environment requiring high levels of honesty, had a significant negative correlation with self-monitoring. These results add to the validity of the JCE and add information to the area of vocational interest assessment.

Laparoscopic sleeve gastrectomy (LSG) incidence continues to increase worldwide because of its efficacy and low surgical risks. This study aimed to investigate satisfaction with eating and the change in taste perception, desire, and enjoyment of flavor changes and associations with extent of percentage excess weight loss (%excess weight loss (EWL)) post-LSG. One hundred six participants completed an online questionnaire 4 to 6 weeks as well as 6 to 8 months post-LSG bariatric surgery. The questionnaire included study-specific questions about changes in taste, desire, and enjoyment of eight major categories of flavor, as well as the Suter Quality of Alimentation Questionnaire to measure satisfaction with eating. The majority of participants reported a post-surgery increase in the intensity of the flavor of sweet (60, 55%) and fatty (57, 70%) at both time points, respectively. Participants also reported a decreased enjoyment for sweet (77, 61%) and fatty (77, 83%) flavors and decreased desire for fatty (83, 84%) and sweet (82, 68%) flavors at both time periods. This study found an increase in intensity of flavor of all eight taste modalities and a decrease in desire and enjoyment of all taste modalities except salty and savory flavors following surgery. Participants reported an increased acuity of spicy flavors and fatty tastes over time, and the desire and enjoyment of sweet, bitter, and metallic flavors increased over time. Changes in savory enjoyment over a 6- to 8-month period post-LSG were weakly associated with extent of % EWL at 6 months post-surgery. The participants reported average (40, 37%), good (33, 42%), and excellent (15, 11%) satisfaction with eating at both time points. This preliminary study indicates that subjective changes in taste, desire, and enjoyment of flavors of eight taste modalities are very common after LSG.

Women's sexual desire and arousal disorders.

A committee of five was convened to update the chapter on women's sexual dysfunctions from the perspective of diagnostic issues, pathophysiology, assessment, and treatment. To review the literature since 2003 and provide recommendations based on evidence. Research databases, conference proceedings, and articles in press were read for relevant new data on these topics for hypoactive sexual desire disorder (HSDD), female sexual arousal disorder (FSAD), female orgasmic disorder (FOD), and persistent genital arousal disorder (PGAD). Recommendations by five experts from five countries were formulated with associated grades. The definitions of HSDD, FSAD, and FOD in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text-Revised are imperfect and have been criticized over the last decade. Proposed new criteria that take into account empirical findings and the diversity across women are recommended. There has been a flurry of new epidemiological studies on women's sexual dysfunction; studies also assessing distress consistently find a much lower prevalence of dysfunction if distress is considered. Assessment of sexual difficulties is best achieved through a biopsychosocial clinical interview of the woman and her partner (if possible); though laboratory investigations, a physical examination, psychophysiological measurement, and self-report questionnaires can often supplement the interview information. There are currently no approved pharmacological treatments for women's sexual dysfunction in North America, though a number of promising agents have been studied. Evidence for the efficacy of psychological treatments is based on limited studies. There is an urgent need for more data on the assessment, etiology, and treatment of PGAD. Specific recommendations for the assessment and treatment of women's desire, arousal, and orgasm disorders are forwarded; however, more research into these domains is needed.

Hemoglobin Le Lamentin (α20(B1)His→Gln) is a ubiquitous variant that has been previously described in a small number of isolated patients. We report the incidental observation of Hb Le Lamentin in a large population from the province of Albacete, in southeastern Spain. Our study investigates possible reasons for the elevated number of carriers of this variant and its implications for the management of diabetes in our region. The subjects are 32 diabetic patients whose hemoglobin displayed an unusual peak while they were being tested for glycated hemoglobin at the laboratory of the University General Hospital of Albacete over a 3-year period. Measurements were made by high performance liquid chromatography using a Variant™ II Turbo Kit-2.0, and subsequently the samples of the 32 patients with anomalous peaks were sent to the Hospital Clínico San Carlos (Madrid, Spain) for molecular characterization of any Hb variants. Molecular studies revealed 31 out of 32 patients heterozygous for Le Lamentin, and in one of them, Hb City of Hope was associated with Hb Le Lamentin. The remaining patient was homozygous for the Le Lamentin mutation. Additionally, most patients were native to the northeastern half of the province of Albacete and were unrelated. Our study describes the largest finding to date of hemoglobin Le Lamentin in a sample of patients. The fact that our region has been perpetually depopulated, with a population that has remained stable in small localities over the centuries, may have favored the survival of the mutation. Since the presence of this variant underestimates the true value of glycated hemoglobin measured by HPLC, it is necessary to systematically review chromatograms.

In this paper a 3D model for coupling of magnetic and electric equations is presented. The magnetic equations are solved with the help of finite element method using the magnetic vector potential formulation. To take into account the effects of magnetic saturation we use the Newton-Raphson algorithm. We develop the analysis permitting the coupling of magnetic and electric equations to obtain a difrerential system equations which can be solved with numerical integration. As example we model an iron core coil and the validity of our model is verified by a comparison of the obtained results with an analytical solution and a 2D code calculation. Dans cet article est présenté un modèle 3D qui permet de coupler les équations magnétiques et électriques. Les équations magnétiques sont résolues à l'aide de la méthode des éléments finis en utilisant une formulation en potentiel vecteur magnétique. Dans le modèle proposé les effets de la saturation du circuit magnétique sont pris en compte en utilisant l'algorithme de Newton-Raphson. On montre comment relier les équations magnétiques avec celles du circuit électrique pour aboutir à un système d'équations différentielles que l'on résout avec une intégration numérique. A titre d'exemple on modélise une bobine à noyau ferromagnétique et pour montrer la validité du modèle on compare les résultats obtenus avec une solution analytique et un code de calcul 2D.

Touching moments: desire modulates the neural anticipation of active romantic caress

PubMed Central

Ebisch, Sjoerd J.; Ferri, Francesca; Gallese, Vittorio

2014-01-01

A romantic caress is a basic expression of affiliative behavior and a primary reinforcer. Given its inherent affective valence, its performance also would imply the prediction of reward values. For example, touching a person for whom one has strong passionate feelings likely is motivated by a strong desire for physical contact and associated with the anticipation of hedonic experiences. The present study aims at investigating how the anticipatory neural processes of active romantic caress are modulated by the intensity of the desire for affective contact as reflected by passionate feelings for the other. Functional magnetic resonance imaging scanning was performed in romantically involved partners using a paradigm that allowed to isolate the specific anticipatory representations of active romantic caress, compared with control caress, while testing for the relationship between neural activity and measures of feelings of passionate love for the other. The results demonstrated that right posterior insula activity in anticipation of romantic caress significantly co-varied with the intensity of desire for union with the other. This effect was independent of the sensory-affective properties of the performed touch, like its pleasantness. Furthermore, functional connectivity analysis showed that the same posterior insula cluster interacted with brain regions related to sensory-motor functions as well as to the processing and anticipation of reward. The findings provide insight on the neural substrate mediating between the desire for and the performance of romantic caress. In particular, we propose that anticipatory activity patterns in posterior insula may modulate subsequent sensory-affective processing of skin-to-skin contact. PMID:24616676

Urban Planning by Le Corbusier According to Praxeological Knowledge

2017-12-01

The city is formed as a mosaic of various elements which affect its attractiveness. These elements range from location attributes, through economic opportunities, to social aspects. Therefore, urbanity and urban planning should be considered in a multi-dimensional context. In the paper we address the problem of urban planning by Le Corbusier according to praxeological and system knowledge. From praxeological point of view an active human being takes his/her choice between various possibilities by preferring one of these possibilities to the others, and by manifesting it by her actions. The same applies to the design process. Due to this fact, the scientific design process can be treated as a systematic rational reconstruction of the designer’s behaviour. Such a reconstruction requires previous reflection on designer’s work, as well as some consideration and design experience, thus know-how knowledge based on methodological knowledge. In the paper several city visions of Le Corbusier, as well as the characteristics and organisation of his design process are analysed. Le Corbusier’s innovative design ideas resulted from industrialisation changes and motorisation accelerating progress, which gave foundation to a new urban array. This array based on strict geometric forms, regularity and repetition determining standard. Thanks to his theories, Le Corbusier established principles of modern city construction and planning. Although some doubts were expressed as to the scale of centralisation of the cities designed by him and his class-based conception, he was awarded that overall welfare of the individual living in a city was the quality of built environment. Therefore, his designed creations were not only functional but they also produced emotions. The analysis of his prolific design activities allows us to state that the organisation of his architectural and urban planning process was very efficient and complex. The city concepts proposed by him were the subject

As access to antiretroviral therapy increases, more HIV-infected patients in sub-Saharan Africa may desire fertility. We conducted a cross-sectional study of reproductive health knowledge, attitudes and practices to identify factors associated with desired fertility among women and men receiving care at two large public HIV clinics in Lilongwe, Malawi. Research assistants administered questionnaires to participants. We performed descriptive, bivariable and multivariable analysis of factors related to desired fertility and of factors related to contraceptive non-use among participants who did not desire fertility. One-third of participants desired future children. Having a partner who desired fertility and having lower parity were associated with desiring children among both genders. For women, believing that pregnancy was unhealthy was associated with decreased fertility desire. Fifty-five percent of women and 69% of men who did not want children in the future reported using contraception at last intercourse. Increasing age, lower parity, and making the decision to use contraception herself were associated with contraceptive non-use among women who did not desire fertility. Having discussed family planning with his partner was associated with contraceptive use among men who did not desire fertility. Knowledge of these factors can guide reproductive health counseling and service provision.

Appetitive responses to sexual stimuli are attenuated in individuals with low levels of sexual desire.

Despite the high prevalence of sexual desire disorders, little is known about their biological underpinnings in humans. Animal studies suggest that dopamine is involved in appetitive sexual behavior; thus, one aim of this study was to elucidate that relationship in humans. This study used measurement of the acoustic startle response (ASR) and prepulse inhibition of the startle response (PPI) as psychophysiological indicators of changes in motivational states to assess the potential relation between sexual desire and appetitive motivation in humans. Responses to sexually provocative stimuli consisting of single nude men and single nude women in a sample of 153 participants (77 men, 76 women) were assessed. The results indicated that ASR was attenuated after exposure to appetitive stimuli (i.e., sexually provocative pictures of attractive individuals) to a greater extent among participants with higher levels of sexual desire, as measured by the Sexual Desire Inventory-2 (Spector, I. P., Carey, M. P., & Steinberg, L. (1996). Journal of Sex & Marital Therapy, 22, 175-190). In addition, PPI was inversely associated with subjective ratings across stimuli such that greater subjective levels of desire were correlated with lower levels of PPI. In general, these results suggest that individuals with lower levels of sexual desire may have a diminished physiological response to appetitive sexual stimuli.

Self-reported sexual desire in homosexual men and women predicts preferences for sexually dimorphic facial cues.

2013-07-01

Recent studies investigating the relationship between self-reported sexual desire and attraction to same- and opposite-sex individuals have found that homosexual men's sexual desire is positively correlated with their self-reported attraction to own-sex individuals only, while homosexual women's sexual desire is positively correlated with their self-reported attraction to both men and women. These data have been interpreted as evidence that sexual desire strengthens men's pre-existing (i.e., dominant) sexual behaviors and strengthens women's sexual behaviors in general. Here we show that homosexual men's (n = 106) scores on the Sexual Desire Inventory-2 (SDI-2) were positively correlated with their preferences for exaggerated sex-typical shape cues in own-sex, but not opposite-sex, faces. Contrary to the hypothesis that sexual desire strengthens women's preferences for sexual dimorphism generally, homosexual women's (n = 83) SDI-2 scores were positively correlated with their preferences for exaggerated sex-typical shape cues in opposite-sex faces only. Together with previous research in heterosexual subjects, our findings support the proposal that sexual desire increases the incidence of existing sexual behaviors in homosexual and heterosexual men, and increases the incidence of sexual responses more generally in heterosexual women, although not necessarily in homosexual women.

Body Image in Dyadic and Solitary Sexual Desire: The Role of Encoding Style and Distracting Thoughts.

Dosch, Alessandra; Ghisletta, Paolo; Van der Linden, Martial

2016-01-01

This study explored the link between body image and desire to engage in sexual activity (dyadic and solitary desire) in adult women living in a long-term couple relationship. Moreover, it considered two psychological factors that may underlie such a link: the occurrence of body-related distracting thoughts during sexual activity and encoding style (i.e., the tendency to rely on preexisting internal schemata versus external information at encoding). A total of 53 women (29 to 47 years old) in heterosexual relationships completed questionnaires assessing sexual desire (dyadic, solitary), body image, body-related distracting thoughts during sexual activity, and encoding style. Results showed that poor body image was associated with low dyadic and solitary sexual desire. Body-related distracting thoughts during sexual activity mediated the link between body image and solitary (but not dyadic) sexual desire. Finally, the mediation of body-related distracting thoughts between body image and solitary sexual desire was moderated by encoding style. A negative body image promoted the occurrence of body-related distracting thoughts during sexual activity, especially in internal encoders. Our study highlights the importance of body image, distracting thoughts, and encoding style in women's solitary sexuality and suggests possible factors that may reduce the impact of those body-related factors in dyadic sexual desire.

2016-09-01

Consumption of alcohol mixed with energy drinks (AmED) has been associated with a variety of risks beyond that observed with alcohol alone. Consumers of AmED beverages are more likely to engage in heavy episodic (binge) drinking. This study was to investigate whether the consumption of high caffeine energy drink mixers with alcohol would increase the desire to drink alcohol compared to the same amount of alcohol alone using a double-blind, within-subjects, placebo-controlled study design. Participants (n = 26) of equal gender who were social drinkers attended 6 double-blind dose administration sessions that involved consumption of alcohol and energy drinks, alone and in combination. On each test day, participants received 1 of 6 possible doses: (i) 1.21 ml/kg vodka + 3.63 ml/kg decaffeinated soft drink, (ii) 1.21 ml/kg vodka + 3.63 ml/kg energy drink, (iii) 1.21 ml/kg vodka + 6.05 ml/kg energy drink, (iv) 3.63 ml/kg decaffeinated soft drink, (v) 3.63 ml/kg energy drink, and (vi) 6.05 ml/kg energy drink. Following dose administration, participants repeatedly completed self-reported ratings on the Desire-for-Drug questionnaire and provided breath alcohol readings. Alcohol alone increased the subjective ratings of "desire for more alcohol" compared to placebo doses. Energy drink mixers with the alcohol increased desire for more alcohol ratings beyond that observed with alcohol alone. This study provides laboratory evidence that AmED beverages lead to greater desire to drink alcohol versus the same amount of alcohol consumed alone. The findings are consistent with results from animal studies indicating that caffeine increases the rewarding and reinforcing properties of alcohol.

Unintended, but still blameworthy: the roles of awareness, desire, and anger in negligence, restitution, and punishment.

PubMed

Laurent, Sean M; Nuñez, Narina L; Schweitzer, Kimberly A

2016-11-01

Two experiments (Experiment 1 N = 149, Experiment 2 N = 141) investigated how two mental states that underlie how perceivers reason about intentional action (awareness of action and desire for an outcome) influence blame and punishment for unintended (i.e., negligent) harms, and the role of anger in this process. Specifically, this research explores how the presence of awareness (of risk in acting, or simply of acting) and/or desire in an acting agent's mental states influences perceptions of negligence, judgements that the acting agent owes restitution to a victim, and the desire to punish the agent, mediated by anger. In both experiments, awareness and desire led to increased anger at the agent and increased perception of negligence. Anger mediated the effect of awareness and desire on negligence rather than negligence mediating the effect of mental states on anger. Anger also mediated punishment, and negligence mediated the effects of anger on restitution. We discuss how perceivers consider mental states such as awareness, desire, and knowledge when reasoning about blame and punishment for unintended harms, and the role of anger in this process.

There is a lack of consensus regarding the qualities possessed by the ideal doctor, and very limited research regarding the views of medical students on these qualities. To investigate the views of commencing medical students regarding the desirable qualities of doctors. A survey containing a set of proposed desirable qualities of doctors identified from the existing literature was completed by 158 first-year medical students. The survey had a 75% response rate. Students rated the individual qualities of empathy, motivation to be a doctor, good verbal communication, ethically sound, integrity and honesty as the most important. A factor analysis identified six categories of qualities: methodical processing, cognitive capacity, people skills, generic work ethic, role certainty and warmth. Significant differences in factor scores were found across subgroups of students (international and domestic students, with and without prior tertiary studies) on the following factors: methodical processing, which was scored highest by domestic students with prior tertiary studies, cognitive capacity, which was scored highest by domestic students without prior tertiary studies and generic work ethic, which was scored highest by international students. Medical students identified a range of desirable personal qualities of a doctor which varied according to student characteristics, including their prior educational experience. Future research aiming to define such desirable qualities should include a broader range of stakeholders, including students at different training levels and institutions.

A learned artisan debates the system of the world: Le Clerc versus Mallemant de Messange.

PubMed

Rabinovitch, Oded

2017-12-01

Sébastien Le Clerc (1637-1714) was the most renowned engraver of Louis XIV's France. For the history of scientific publishing, however, Le Clerc represents a telling paradox. Even though he followed a traditional route based on classic artisanal training, he also published extensively on scientific topics such as cosmology and mathematics. While contemporary scholarship usually stresses the importance of artisanal writing as a direct expression of artisanal experience and know-how, Le Clerc's publications, and specifically the work on cosmology in his Système du monde (1706-1708), go far beyond this. By reconstructing the debate between Le Clerc and the professor Mallemant de Messange on the authorship of this 'system of the world', this article argues that Le Clerc's involvement in publishing ventures shaped his identity both as an artisan and as a scientific author. Whereas the Scientific Revolution supposedly heralded a change from the world of 'more or less' to the 'world of precision', this article shows how an artisan could be more 'precise' than the learned scholar whose claims he disputed, and points to the importance of the literary field as a useful lens for observing the careers of early modern scientific practitioners.

Younger people are perceived as possessing a host of socially desirable attributes, some of which are the same traits attributed to attractive people. In the present study, 160 younger and older White Canadians rated the attractiveness and personality traits of 1 of 4 target women. The results indicated an interaction between the participant's age and gender and the age and attractiveness of the target person. Both younger and older judges showed an attractiveness bias and downrated the social desirability of younger unattractive targets. Younger judges rated younger and older attractive targets as equal in social desirability. Older male judges rated older attractive targets as less socially desirable than younger attractive targets. Results are discussed in terms of cultural expectations of beauty.

Recent trends in fertility rates indicate declines in total fertility rate (TFR) in some sub-Saharan African countries. However, countries such as Uganda continue to have a persistently high TFR partly attributed to strong preferences for large family sizes. We explored the factors that influence fertility desire among married or cohabiting individuals in Rakai, a rural district in southwestern Uganda. This cross-sectional study of fertility desire (desire to have another child) was nested in a cluster-randomized demand-creation intervention trial for the promotion of couples' HIV counseling and testing uptake among married or cohabiting individuals that was conducted in Rakai district between March 1 and April 30, 2015. A total of 1490 married or cohabiting individuals, resident in three study regions with differing background HIV prevalence, were enrolled into the study. Data were collected on socio-demographic, behavioral and fertility-related characteristics. We used a modified Poisson regression model to generate prevalence ratio (PR) as a measure of association for factors that were independently associated with fertility desire. We adjusted for clustering at community level and used STATA version 14.0 for all analyses. Overall, fertility desire was high (63.1%, n = 940); higher in men (69.9%, n = 489) than women (57.1%, n = 451). More than three-quarters (78.8%, n = 1174) had 3+ biological children while slightly more than two-thirds (68.5%, n = 1020) reported an ideal family size of 5+ children. Only 30% (n = 452) reported that they had attained their desired family size. After adjusting for potential and suspected confounders, the factors that were negatively associated with fertility desire were: age 30-39 (adjusted prevalence ratio [aPR] = 0.82, 95% CI: 0.78, 0.86) and 40+ years (aPR = 0.65, 95% CI: 0.60, 0.71); having six or more biological children (aPR = 0.88, 95% CI: 0.80, 0.97); being HIV-positive (aPR = 0

Un sous-comité du Comité consultatif national de l'Agence de santé publique du Canada sur l'Ensemble des troubles causés par l'alcoolisation fœtale a examiné, analysé et intégré les méthodes de diagnostic actuelles afin de parvenir à une méthode de diagnostic normalisée faisant le consensus au Canada. L'objet du présent document est d'examiner et de clarifier l'utilisation des systèmes de diagnostic actuels et de formuler des recommandations quant à leur application pour le diagnostic des déficiences liées à l'ETCAF chez des individus de tous les âges. Les lignes directrices sont fondées sur un vaste consensus de praticiens et d'autres intervenants spécialisés dans le domaine. Ces lignes directrices ont été organisées en sept catégories, soit le dépistage et l'orientation vers les spécialistes, l'examen physique et le diagnostic différentiel, l'évaluation du comportement neurologique, le traitement et le suivi, les antécédents de consommation d'alcool de la mère pendant la grossesse, les critères du diagnostic pour le syndrome d'alcoolisation fœtale (SAF), SAF partiel et troubles neurologiques du développement liés à l'alcool, l'harmonisation de l'Institute of Medicine (IOM) et des approches du Code diagnostique à 4 chiffres. Le diagnostic exige une évaluation complète des antécédents, ainsi qu'un examen physique et du comportement neurologique, tout en recourant à une approche multidisciplinaire. Les présentes lignes directrices pour le diagnostic du syndrome d'alcoolisation fœtale et des déficiences qui y sont associées sont les premières à avoir été élaborées au Canada et elles sont fondées sur la consultation d'un grand éventail de spécialistes du diagnostic.

Objectives. We examined the associations of pregnancy desire (ambivalence or happiness about a pregnancy in the next year) and recent pregnancy attempts with hopelessness and self-worth among low-income adolescents. Methods. To evaluate independent associations among the study variables, we conducted gender-stratified multivariable logistic regression analyses with data derived from 2285 sexually experienced 9- to 18-year-old participants in the Mobile Youth Survey between 2006 and 2009. Results. Fifty-seven percent of youths reported a desire for pregnancy and 9% reported pregnancy attempts. In multivariable analyses, hopelessness was positively associated and self-worth was negatively associated with pregnancy attempts among both female and male youths. Hopelessness was weakly associated (P = .05) with pregnancy desire among female youths. Conclusions. The negative association of self-worth and the positive association of hopelessness with pregnancy attempts among young men as well as young women and the association of hopelessness with pregnancy desire among young women raise questions about why pregnancy is apparently valued by youths who rate their social and cognitive competence as low and who live in an environment with few options for material success.

Tilgner, Linda; Wertheim, Eleanor H; Paxton, Susan J

2004-03-01

The current study examined whether a social desirability response bias is a source of measurement error in prevention research. Six hundred and seventy-seven female students in Grade 7 (n = 345) and Grade 8 (n = 332) were divided into either an intervention condition, in which participants watched a videotape promoting body acceptance and discouraging dieting and then discussed issues related to the video, or a control condition. Questionnaires were completed at baseline, postintervention, and at 1-month follow-up. Social desirability scores were correlated at a low but significant level with baseline body dissatisfaction, drive for thinness, bulimic tendencies, intention to diet, and size discrepancy for intervention participants. Social desirability did not correlate significantly with change over time in the outcome measures. The findings suggested that changes in girls' self-reports related to a prevention program were relatively free of social desirability response bias. Copyright 2004 by Wiley Periodicals, Inc.

Belief-desire reasoning in the explanation of behavior: do actions speak louder than words?

PubMed

Wertz, Annie E; German, Timsin C

2007-10-01

The mechanisms underwriting our commonsense psychology, or 'theory of mind', have been extensively investigated via reasoning tasks that require participants to predict the action of agents based on information about beliefs and desires. However, relatively few studies have investigated the processes contributing to a central component of 'theory of mind' - our ability to explain the action of agents in terms of underlying beliefs and desires. In two studies, we demonstrate a novel phenomenon in adult belief-desire reasoning, capturing the folk notion that 'actions speak louder than words'. When story characters were described as searching in the wrong place for a target object, adult subjects often endorsed mental state explanations referencing a distracter object, but only when that object was approached. We discuss how this phenomenon, alongside other reasoning "errors" (e.g., hindsight bias; the curse of knowledge) can be used to illuminate the architecture of domain specific belief-desire reasoning processes.

Despite a growing literature assessing pregnancy desires among HIV-infected women enrolled in clinical care, little attention has been paid to HIV-infected youth for whom pregnancy is a very relevant issue. In urban areas with high rates of teen pregnancy and HIV infection, further understanding of childbearing motivations and relationship dynamics influencing pregnancy desires among female youth is needed. This study compares the childbearing motivations, pregnancy desires, and perceived partner desire for a pregnancy among predominately African American HIV-infected (n=46) and HIV-uninfected (n=355) female youth (15-24 years). An HIV-infected status was not significantly associated with childbearing motivations or the desire for a future pregnancy, p> 0.10. HIV-infection was, however, associated with an increased likelihood to perceive that one's partner would have a positive response to a pregnancy (OR 2.7, p=0.03) compared to uninfected peers. While race was not associated with participants' own desire for a child, white youth were significantly less likely to perceive a positive partner response to becoming pregnant than their African American peers (aOR 0.23 (.09-.56), p=0.001). These data suggest that the desire for childbearing is not diminished by HIV infection among urban female youth, highlighting the need for routine, provider-initiated discussions about childbearing with urban youth to minimized unintended pregnancies and HIV transmission.

Abstract Aims To describe levels of sexual desire across the menopausal transition (MT) and early postmenopause (PM), including effects of age, MT-related factors, health, stress, symptoms (hot flash, sleep, mood), and social opportunity factors. Methods A subset of Seattle Midlife Women's Health Study (SMWHS) participants who provided data during the early reproductive, early and late menopausal transition stages, or postmenopause (n = 286), including menstrual calendars for staging the MT, annual health reports between 1990 and 2005, and morning urine samples assayed for estrone glucuronide (E1G), testosterone (T), and follicle-stimulating hormone (FSH) was included. Multilevel modeling using the R program was used to test factors related to sexual desire. Results Women experienced a significant decrease in sexual desire during the late MT stage (p < 0.01) and early PM (p < 0.0001). Those with higher urinary E1G and T reported significantly higher levels of sexual desire, whereas those with higher FSH levels reported significantly lower sexual desire (p < 0.0001, 0.06, and 0.0002, respectively). Women using hormone therapy also reported higher sexual desire (p = 0.02). Those reporting higher perceived stress reported lower sexual desire (p < 0.0001), but history of sexual abuse did not have a significant effect. Those most troubled by symptoms of hot flashes, fatigue, depressed mood, anxiety, difficulty getting to sleep, early morning awakening, and awakening during the night also reported significantly lower sexual desire (p range from <0.03 to 0.0001), but there was no effect of vaginal dryness. Women with better perceived health reported higher sexual desire (p < 0.0001), and those reporting more exercise and more alcohol intake also reported greater sexual desire (p < 0.0001). Having a partner was associated with lower sexual desire. Conclusions Clinicians working with women traversing the MT should be aware that promoting

The desired moral attitude of the physician: (III) care.

PubMed

Gelhaus, Petra

2013-05-01

In professional medical ethics, the physician traditionally is obliged to fulfil specific duties as well as to embody a responsible and trustworthy personality. In the public discussion, different concepts are suggested to describe the desired moral attitude of physicians. In a series of three articles, three of the discussed concepts are presented in an interpretation that is meant to characterise the morally emotional part of this attitude: "empathy", "compassion" and "care". In the first article of the series, "empathy" has been developed as a mainly cognitive and morally neutral capacity of understanding. In the second article, the emotional and virtuous core of the desired professional attitude-compassion-has been presented. Compassion as a professional attitude has been distinguished from a spontaneous feeling of compassion, and has been related to a general idea of man as vulnerable and solidary being. Thus, the dignity of the patient is safeguarded in spite of the asymmetry of compassion. In this article, the third concept of the triad-"care"-is presented. Care is conceived as an attitude as well as an activity which can be directed to different objects: if it is directed to another sentient being, it is regarded as intrinsically morally valuable; implying (1) the acceptance of being addressed, (2) a benevolent inclination to help and to foster, and (3) activity to realize this. There are different forms of benevolence that can underlie caring. With regard to the professional physician's ethos, the attitude of empathic compassion as developed in the two previous articles is proposed to be the adequate underlying attitude of care which demands the right balance between closeness and professionalism and the right form of attention to the person of the patient. 'Empathic compassionate care' does not, however, describe the whole of the desired attitude of a physician, but focuses on the morally-emotive aspects. In order to get also the cognitive and practical

Mise à jour sur le nouveau vaccin 9-valent pour la prévention du virus du papillome humain

Résumé Objectif Informer les médecins de famille quant à l’efficacité, à l’innocuité, aux effets sur la santé publique et à la rentabilité du vaccin 9-valent contre le virus du papillome humain (VPH). Qualité des données Des articles pertinents publiés dans PubMed jusqu’en mai 2015 ont été examinés et analysés. La plupart des données citées sont de niveau I (essais randomisés et contrôlés et méta-analyses) ou de niveau II (études transversales, cas-témoins et épidémiologiques). Des rapports et recommandations du gouvernement sont aussi cités en référence. Message principal Le vaccin 9-valent contre le VPH, qui offre une protection contre les types 6, 11, 16, 18, 31, 33, 45, 52 et 58 du VPH, est sûr et efficace et réduira encore plus l’incidence des infections à VPH, de même que les cas de cancer lié au VPH. Il peut également protéger indirectement les personnes non immunisées par l’entremise du phénomène d’immunité collective. Un programme d’immunisation efficace peut prévenir la plupart des cancers du col de l’utérus. Les analyses montrent que la rentabilité du vaccin 9-valent chez les femmes est comparable à celle du vaccin quadrivalent original contre le VPH (qui protège contre les types 6, 11, 16 et 18 du VPH) en usage à l’heure actuelle. Toutefois, il faut investiguer plus en profondeur l’utilité d’immuniser les garçons avec le vaccin 9-valent contre le VPH. Conclusion en plus d’être sûr, le vaccin 9-valent protège mieux contre le VPH que le vaccin quadrivalent. Une analyse coûtefficacité en favorise l’emploi, du moins chez les adolescentes. Ainsi, les médecins devraient recommander le vaccin 9-valent à leurs patients plutôt que le vaccin quadrivalent contre le VPH.

Evaluer l'efficacité et l'innocuité de l'utilisation du misoprostol par voie vaginale pour le déclenchement du travail à terme. Etude prospective réalisée au service de gynécologie obstétrique B de l'hôpital Charles Nicolle de Tunis sur une durée de 4 mois. La population sélectionnée concernait les patientes à terme devant bénéficier d'une maturation cervicale. Le misoprostol à la dose de 50 µg par voie vaginale toutes les 12 h était utilisé. Les paramètres étudiés étaient les anomalies contractiles, les anomalies du RCF, le mode d'accouchement, le délai d'accouchement et l’état néonatal. 44 patientes ont bénéficié d'une maturation cervicale par misoprostol. Le terme moyen était de 40 SA. Le taux de nullipare était de 23/44 (52%). Le taux d'accouchement par voie basse était de 31/44 (70.4%). 84% des patientes ont reçu une seule dose de misoprostol. Les anomalies du RCF ont été notées dans 14/44 (32%). Le taux de liquides méconiaux était de 12/44 (27%). Un score d'Apgar à 5 mn inférieur à 7 était noté chez 7/44 (16%). Un cas de rupture utérine était survenue chez une primipare et ce après une seule prise de misoprostol. Nos résultats sont décevants en raison de la survenue d'une rupture utérine et d'une morbidité néonatale importante. D'autres études prospectives multicentriques restent utiles pour mieux s'assurer de l'efficacité mais surtout de l'innocuité du misoprostol à dose faible pour le déclenchement du travail à terme.

LeCTR2, a CTR1-like protein kinase from tomato, plays a role in ethylene signalling, development and defence

PubMed Central

Lin, Zhefeng; Alexander, Lucy; Hackett, Rachel; Grierson, Don

2008-01-01

Arabidopsis AtCTR1 is a Raf-like protein kinase that interacts with ETR1 and ERS and negatively regulates ethylene responses. In tomato, several CTR1-like proteins could perform this role. We have characterized LeCTR2, which has similarity to AtCTR1 and also to EDR1, a CTR1-like Arabidopsis protein involved in defence and stress responses. Protein–protein interactions between LeCTR2 and six tomato ethylene receptors indicated that LeCTR2 interacts preferentially with the subfamily I ETR1-type ethylene receptors LeETR1 and LeETR2, but not the NR receptor or the subfamily II receptors LeETR4, LeETR5 and LeETR6. The C-terminus of LeCTR2 possesses serine/threonine kinase activity and is capable of auto-phosphorylation and phosphorylation of myelin basic protein in vitro. Overexpression of the LeCTR2 N-terminus in tomato resulted in altered growth habit, including reduced stature, loss of apical dominance, highly branched inflorescences and fruit trusses, indeterminate shoots in place of determinate flowers, and prolific adventitious shoot development from the rachis or rachillae of the leaves. Expression of the ethylene-responsive genes E4 and chitinase B was upregulated in transgenic plants, but ethylene production and the level of mRNA for the ethylene biosynthetic gene ACO1 was unaffected. The leaves and fruit of transgenic plants also displayed enhanced susceptibility to infection by the fungal pathogen Botrytis cinerea, which was associated with much stronger induction of pathogenesis-related genes such as PR1b1 and chitinase B compared with the wild-type. The results suggest that LeCTR2 plays a role in ethylene signalling, development and defence, probably through its interactions with the ETR1-type ethylene receptors of subfamily I. PMID:18346193

Planning for success: desired characteristics of special operations surgeons, a pilot study.

Campbell, Barrett H; Alderman, Shawn M

2012-01-01

Selection criteria for Special Operations Forces (SOF) physicians are often unclear to potential candidates without prior SOF experience. To date, no published career resource exists to guide the careers of physicians interested in becoming a SOF surgeon. Using a survey tool, desirable characteristics and personal attributes were identified that can be used to inform candidate career decisions and better prepare them for a future position in Special Operations. A descriptive, cross-sectional survey instrument was developed and distributed to current Army SOF Command Surgeons for further distribution to subordinate surgeons. RESULTS were analyzed as a cohort and by subordinate command. Respondents consisted of current SOF Surgeons. Uniformly, the individual characteristics most strongly desired are professionalism, being a team player, and leadership. Possessing or obtaining Airborne and Flight Surgeon qualifications prior to consideration for a surgeon position was highly desired. Residency training within Family Medicine or Emergency Medicine constituted the vast majority of specialty preference. Understanding which characteristics and attributes are desirable to current surgeons and commanders can aid physicians interested in SOF surgeon positions. Using this study and future studies can guide career planning and foster the selection of ideally trained physicians who will operate at the tip of the spear.

The purposes of this research were to investigate factors influencing patients' satisfaction with their present dental esthetic, received previous dental treatments on anterior teeth and basic treatments that they wanted to undergo to improve their dental appearance. A total of 1014 patients who attended a dental school in a major city in Turkey participated in the study. The participants were surveyed with a questionnaire containing questions about gender, age, education level, self-reported tooth appearance, received previous dental treatments on anterior teeth and desired basic esthetic dental treatments. Statistical analysis of the verifying data was made with descriptive statistics, chi2 test and multiple logistic regression analyses. According to the analyses of the verifying data, 55.1% of the patients were dissatisfied with the color of their teeth, 42.7% with dental appearance, 29.9% with crowding of anterior teeth, 23.3% were hiding teeth while smiling, 16.1% had non-esthetic restorations and 11.9% thought that their anterior teeth were protruding. Esthetic restoration was found to be the most-performed treatment recently (29.0%) and whitening of teeth was the most-desired dental treatment (49.0%). Gender, age and education level had an effect on satisfaction and received previous and desired dental treatments for improvement of esthetics. Many of the Turkish patients surveyed in the study were dissatisfied and desired the improvement of dental esthetics. Therefore, dentists should consider this as an important dimension in their practice.

Comparing two books and establishing probably efficacious treatment for low sexual desire.

Balzer, Alexandra M; Mintz, Laurie B

2015-04-01

Using a sample of 45 women, this study compared the effectiveness of a previously studied (Mintz, Balzer, Zhao, & Bush, 2012) bibliotherapy intervention (Mintz, 2009), a similar self-help book (Hall, 2004), and a wait-list control (WLC) group. To examine intervention effectiveness, between and within group standardized effect sizes (interpreted with Cohen's, 1988 benchmarks .20 = small, .50 = medium, .80+ = large) and their confidence limits are used. In comparison to the WLC group, both interventions yielded large between-group posttest effect sizes on a measure of sexual desire. Additionally, large between-group posttest effect sizes were found for sexual satisfaction and lubrication among those reading the Mintz book. When examining within-group pretest to posttest effect sizes, medium to large effects were found for desire, lubrication, and orgasm for both books and for satisfaction and arousal for those reading the Mintz book. When directly comparing the books, all between-group posttest effect sizes were likely obtained by chance. It is concluded that both books are equally effective in terms of the outcome of desire, but whether or not there is differential efficacy in terms of other domains of sexual functioning is equivocal. Tentative evidence is provided for the longer term effectiveness of both books in enhancing desire. Arguing for applying criteria for empirically supported treatments to self-help, results are purported to establish the Mintz book as probably efficacious and to comprise a first step in this designation for the Hall book.

Le niobate de lithium a haute temperature pour les applications ultrasons =

NASA Astrophysics Data System (ADS)

De Castilla, Hector

L'objectif de ce travail de maitrise en sciences appliquees est de trouver puis etudier un materiau piezoelectrique qui est potentiellement utilisable dans les transducteurs ultrasons a haute temperature. En effet, ces derniers sont actuellement limites a des temperatures de fonctionnement en dessous de 300°C a cause de l'element piezoelectrique qui les compose. Palier a cette limitation permettrait des controles non destructifs par ultrasons a haute temperature. Avec de bonnes proprietes electromecaniques et une temperature de Curie elevee (1200°C), le niobate de lithium (LiNbO 3) est un bon candidat. Mais certaines etudes affirment que des processus chimiques tels que l'apparition de conductivite ionique ou l'emergence d'une nouvelle phase ne permettent pas son utilisation dans les transducteurs ultrasons au-dessus de 600°C. Cependant, d'autres etudes plus recentes ont montre qu'il pouvait generer des ultrasons jusqu'a 1000°C et qu'aucune conductivite n'etait visible. Une hypothese a donc emerge : une conductivite ionique est presente dans le niobate de lithium a haute temperature (>500°C) mais elle n'affecte que faiblement ses proprietes a hautes frequences (>100 kHz). Une caracterisation du niobate de lithium a haute temperature est donc necessaire afin de verifier cette hypothese. Pour cela, la methode par resonance a ete employee. Elle permet une caracterisation de la plupart des coefficients electromecaniques avec une simple spectroscopie d'impedance electrochimique et un modele reliant de facon explicite les proprietes au spectre d'impedance. Il s'agit de trouver les coefficients du modele permettant de superposer au mieux le modele avec les mesures experimentales. Un banc experimental a ete realise permettant de controler la temperature des echantillons et de mesurer leur impedance electrochimique. Malheureusement, les modeles actuellement utilises pour la methode par resonance sont imprecis en presence de couplages entre les modes de vibration. Cela

Dans la première moitié du XXème siècle, alors que la Haute-Volta (actuel Burkina Faso) subissait une terrible épidémie de maladie du sommeil, l’administration coloniale française a orchestré des déplacements massifs de populations de la Haute-Volta vers la Côte d’Ivoire, pour exploiter le territoire. Cela a conduit à la mise en place de villages de colonisation Mossi en zone forestière ivoirienne, comme ceux de Koudougou, issus de l’une des régions les plus peuplées de Haute-Volta, mais aussi l’une des plus touchées par la maladie du sommeil. Depuis 2000, au Burkina Faso, c’est dans le district sanitaire de Koudougou que sont dépistés passivement le plus grand nombre de trypanosomés en provenance de Côte d’Ivoire. Qui sont-ils ? Où habitent-ils au Burkina Faso ? D’où viennent-ils de Côte d’Ivoire ? Après avoir retracé l’histoire épidémiologique des villages de Koudougou au Burkina Faso et en Côte d’Ivoire, nous avons recherché les trypanosomés dépistés passivement depuis 2000 dans le district sanitaire de Koudougou au Burkina Faso. Au total, dix trypanosomés ont été enquêtés. Le processus de propagation de la maladie du sommeil dans l’espace ivoiro-burkinabé a été mis en évidence et des zones à risque de la maladie identifiées dans ce même espace. PMID:23193525

Résumé Ces recommandations sont le fruit d'un processus multidisciplinaire national ayant duré un an et visant à déterminer si et comment l'on pourrait procéder au don d'organes après un décès d'origine cardiocirculatoire («don après le décès cardiocirculatoire», ou DDC) au Canada. Le forum national organisé en février 2005 a permis aux participants de discuter et d'élaborer des recommandations sur les principes, interventions et pratiques se rapportant au DDC. Les aspects éthiques et juridiques ont été abordés dans les discussions. À la fin du Forum, la majorité des participants ont été favorables à l'implantation de programmes de DDC au Canada. Les participants du Forum ont également convenu qu'il fallait formuler et prôner des valeurs fondamentales pour orienter l'élaboration de programmes et de protocoles basés sur le cadre médical, éthique et juridique établi lors de cette réunion. Même si la possibilité d'un don d'organes et de tissus doit faire partie intégrante des soins de fin de vie, il faut insister sur le fait que le devoir de diligence envers les patients mourants et leurs familles doit demeurer la priorité des équipes soignantes. La complexité et les répercussions profondes du décès sont reconnues et doivent être respectées, de même que les différences personnelles, ethnoculturelles et religieuses face à la mort et au don d'organes. Les décisions d'arrêter le traitement de maintien des fonctions vitales, la prise en charge des derniers moments de la vie et le diagnostic de décès selon des critères cardiocirculatoires doivent être distincts et indépendants des processus de don et transplantation. Ce rapport contient des recommandations destinées aux gestionnaires de program, aux autorités sanitaires régionales et aux instances appelés à élaborer les protocoles de DDC. Les programmes doivent être conçus en fonction des éléments suivants : direction et planification locales, éducation et

Population-based studies estimating the prevalence of tooth bleaching desire or the percentage of individuals who had performed this treatment are rare. Thus, the aim of this study was to evaluate the desire to perform tooth bleaching and the prevalence of adult individuals who had performed the treatment and investigate the association of these outcomes. A subsample (n = 536) of the 1982 Pelotas birth cohort in southern Brazil was investigated at the ages 15, 24 and 31 by clinical examinations and interviews. The prevalence of bleaching at 31 years was 15.6% [95%CI 12.6-18.9] while 85.9% [95%CI 82.7-88.7] reported they desired the treatment. Multivariate Poisson regression analysis showed that individuals who have visited the dentist within the last year showed a treatment prevalence ratio (PR) 2.31 times [95%CI 1.40-3.83] higher compared with those who had the last dental visit more than a year before the interview. Similarly, individuals with smoking habits presented an elevated PR of 1.60 [95%CI 1.00-2.55], and the low-income trajectory group showed the largest PR of desire for tooth bleaching (1.17 [95%CI 1.07-1.28]). Moreover, individuals from the high-risk caries trajectory group presented a higher prevalence of desire for tooth bleaching than individuals from low caries trajectory group. Individuals who have declared being "dissatisfied" with their dental color presented a prevalence of desire for tooth bleaching 16% greater than "satisfied" ones. Thus, the present findings confirm that tooth bleaching has become a frequently desired dental treatment to improve dental aesthetics in the population and a considerable rate of adults has performed the treatment.

Characterization of LeMir, a Root-Knot Nematode-Induced Gene in Tomato with an Encoded Product Secreted from the Root1

A tomato gene that is induced early after infection of tomato (Lycopersicon esculentum Mill.) with root-knot nematodes (Meloidogyne javanica) encodes a protein with 54% amino acid identity to miraculin, a flavorless protein that causes sour substances to be perceived as sweet. This gene was therefore named LeMir (L. esculentum miraculin). Sequence similarity places the encoded protein in the soybean trypsin-inhibitor family (Kunitz). LeMir mRNA is found in root, hypocotyl, and flower tissues, with the highest expression in the root. Rapid induction of expression upon nematode infection is localized to root tips. In situ hybridization shows that LeMir is expressed constitutively in the root-cap and root-tip epidermis. The LeMir protein product (LeMir) was produced in the yeast Pichia pastoris for generation of antibodies. Western-blot analysis showed that LeMir expression is up-regulated by nematode infection and by wounding. LeMir is also expressed in tomato callus tissue. Immunoprint analysis revealed that LeMir is expressed throughout the seedling root, but that levels are highest at the root/shoot junction. Analysis of seedling root exudates revealed that LeMir is secreted from the root into the surrounding environment, suggesting that it may interact with soil-borne microorganisms. PMID:9733543

Objective Uganda has an unmet need for family planning of 34% and a total fertility rate of 6.2. We assessed the desire for female sterilization among sexually active women who wanted to stop childbearing in rural Rakai district, Uganda. Study design 7,192 sexually active women enrolled in a community cohort between 2002 and 2008 were asked about fertility intentions. Those stating that they did not want another child (limiters) were asked whether they would be willing to accept female sterilization, if available. Trends in desire for sterilization were determined by Chi-square test for trend, and Modified Poisson regression was used to estimate prevalence rate ratios (PRR) and 95% confidence intervals of the associations between desire for sterilization and socio-demographic characteristics and HIV status. Results From 2002 to 2008, the proportion of limiters dropped (47.2% to 43.7%; p<0.01). Use of pills and injectables among limiters significantly increased, 38.9% to 50.3% (p<0.0001), while use of IUDs and implants declined from 3.3% to 1.7% (p<0.001). The desire for sterilization significantly increased from 54.2% to 63.1% (p<0.0001), and this was consistently higher among the HIV-positive (63.6% to 70.9%, p<0.01) than HIV-negative women (53.3% to 61.2%, p<0.0001). Factors significantly associated with the desire for sterilization included higher number of living children (>=3), being HIV-infected and having received HIV counseling and testing. Conclusion There is latent and growing desire for sterilization in this population. Our findings suggest a need to increase permanent contraception services for women who want to limit childbearing in this setting. PMID:26232377

Puerto Rican adolescents (N = 105; M age  = 15.97 years, SD = 1.40) evaluated hypothetical situations describing conflicts between Latino values (family obligations and respeto) and autonomy desires regarding personal, friendship, and dating activities. Adolescents judged that peers should prioritize Latino values over autonomy, which led to greater feelings of pride than happiness. However, they believed that teens would prioritize autonomy over Latino values, which led to greater feelings of happiness than pride. Adolescents reasoned about autonomy desires as personal issues, whereas reasoning about Latino values was multifaceted, including references to conventions and concerns for others. Furthermore, judgments and reasoning depended on the type of autonomy desire and Latino value and sometimes, by participants' age and sex. © 2016 The Authors.

The desired moral attitude of the physician: (I) empathy.

PubMed

Gelhaus, Petra

2012-05-01

In professional medical ethics, the physician traditionally is obliged to fulfil specific duties as well as to embody a responsible and trustworthy personality. In the public discussion, different concepts are suggested to describe the desired underlying attitude of physicians. In this article, one of them--empathy--is presented in an interpretation that is meant to depicture (together with the two additional concepts compassion and care) this attitude. Therefore empathy in the clinical context is defined as the adequate understanding of the inner processes of the patient concerning his health-related problems. Adequacy is scrutinized on behalf of the emotional and subjective involvement of he physician, and on the necessary dependence on medical-moral-goals. In the present interpretation, empathy alone is no guarantee of the right moral attitude, but a necessary instrumental skill in order to perceive and treat a patient as an individual person. The concepts of compassion and care that will be discussed in two forthcoming articles are necessary parts to describe the desired moral attitude of the physician more completely.

An important basis for adequate psycho-oncological and psychosocial care of cancer patients is the regular assessment of their psychosocial distress and thus their need for care. For this purpose, there are numerous questionnaires available. The objective of the present study was to assess whether distressed patients require professional support and which screening instrument outpatients with skin cancer prefer. In a cross-sectional survey, we asked outpatients with skin cancer to fill out three questionnaires assessing psychosocial stress, and to indicate which one they considered most adequate. Patients were offered the following three instruments: Hornheide Questionnaire (27 items), Hornheide Screening Instrument (7 items), and the Distress Thermometer. In addition, we inquired about the patients' desire for support. (1) Comparing subjective distress and patients' declared desire for support revealed a marked divergence. While one-third of the 137 patients were identified as being in need of care, only 11.5% of the sample requested such support. (2) 63.7% of patients chose the long version of the Hornheide Questionnaire. In addition to their psychosocial burden, patients' desire for support should be assessed. Moreover, apart from screening tools, other ways to provide access to psychosocial care should be considered. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Many trans individuals undergo medical interventions that result in irreversible loss of fertility. Little is known about their desire to have children and attitudes toward fertility preservation options. To study how the desire for children and the use of fertility preservation options varies among trans women and trans men in different transitioning stages in Germany. In this cross-sectional multi-center study, N = 99 trans women and N = 90 trans men were included. Of these, 26 of each sex were just about to start medical treatment. Outcome parameter were the prevalence and determinants of a desire to have children in trans persons. Before treatment, a desire for children was significantly higher in trans men compared to trans women (P = .016). In contrast, in those who had already started treatment, a current desire to have children was equally present in about one fourth of participants of both genders while the interest in having children in the future was significantly higher in trans women (69.9%) than in trans men (46.9%; P = .034). Although 76.1% of trans women and 76.6% of trans men indicated that they had at least thought about preserving germ cells before starting medical transition, only 9.6% of trans women and 3.1% of trans men had put this idea into practice. Most trans men in both groups indicated that insemination of a female partner with sperm from an unrelated donor was a suitable option to fulfill their child wish, potentially explaining their low interest in preserving their own germ cells. Finally, a logistic regression analysis accounting for potential confounders revealed that overall trans women were more than twice as likely to have a current desire to have children (odds ratio 2.58), and this wish was on average 5.3% lower with each year of increasing age. A low level of fertility preservation among trans persons is contrasted by a high level of desire for children. This highlights the importance of counseling trans individuals

The impact of affect on willingness-to-pay and desired-set-size.

PubMed

Hafenbrädl, Sebastian; Hoffrage, Ulrich; White, Chris M

2013-01-01

What role does affect play in economic decision making? Previous research showed that the number of items had a linear effect on the willingness-to-pay for those items when participants were computationally primed, whereas participants' willingness-to-pay was insensitive to the amount when they were affectively primed. We extend this research by also studying the impact of affect on nonmonetary costs of waiting for items to be displayed and of screening them in a computer task. We assessed these costs by asking participants how many items they desired to see before making their selection. In our experiment, the effect of priming on desired-set-size was even larger than on willingness-to-pay, which can be explained by the fact that the nonmonetary costs, waiting time, were real, whereas willingness-to-pay was hypothetical. Participants also reported their satisfaction with the choosing process and the chosen items; no linear or nonlinear relationship was found between the self-determined desired-set-size and satisfaction.

[The desire for a child in today parenthood: Infertility and reproductive techniques].

PubMed

Alkolombre, Patricia

2014-01-01

The advances in reproductive medicine have unprecedentedly expanded the possibilities to form a family. Today we can speak of a diversity of ways to access to parenthood. The paradigm of family formations has also changed following the diversity of parenting projects: heterosexual couples, blended families (post-divorce), couples formed by lesbians and gays and single parenting. The vicissitudes of "desire for a child" under current parenthood lead us to think about their scope in clinical reproductive disorders or infertility and new family configurations. One of the destinies of the desire for a child in women is the "passion for a child", the child at any cost. Thinking of the changes in parenthood in this field involves not only the desire to have a child in a woman, a man or a couple, but also the history of the origins in children. Especially with some of the reproductive techniques used, such as surrogacy and the donation of gametes-eggs (ovum and sperm). In these cases we are dealing with new articulations of blood ties, kinship and parenthood.

Deriving fractional rate of degradation of logistic-exponential (LE) model to evaluate early in vitro fermentation.

Wang, M; Sun, X Z; Tang, S X; Tan, Z L; Pacheco, D

Water-soluble components of feedstuffs are mainly utilized during the early phase of microbial fermentation, which could be deemed an important determinant of gas production behavior in vitro. Many studies proposed that the fractional rate of degradation (FRD) estimated by fitting gas production curves to mathematical models might be used to characterize the early incubation for in vitro systems. In this study, the mathematical concept of FRD was developed on the basis of the Logistic-Exponential (LE) model, with initial gas volume being zero (LE0). The FRD of the LE0 model exhibits a continuous increase from initial (FRD 0) toward final asymptotic value (FRD F) with longer incubation time. The relationships between the FRD and gas production at incubation times 2, 4, 6, 8, 12 and 24 h were compared for four models, in addition to LE0, Generalization of the Mitscherlich (GM), c th order Michaelis-Menten (MM) and Exponential with a discrete LAG (EXPLAG). A total of 94 in vitro gas curves from four subsets with a wide range of feedstuffs from different laboratories and incubation periods were used for model testing. Results indicated that compared with the GM, MM and EXPLAG models, the FRD of LE0 model consistently had stronger correlations with gas production across the four subsets, especially at incubation times 2, 4, 6, 8 and 12 h. Thus, the LE0 model was deemed to provide a better representation of the early fermentation rates. Furthermore, the FRD 0 also exhibited strong correlations (P < 0.05) with gas production at early incubation times 2, 4, 6 and 8 h across all four subsets. In summary, the FRD of LE0 model provides an alternative to quantify the rate of early stage incubation, and its initial value could be an important starting parameter of rate.

Au Tchad, le réseau d'aires protégées couvre près de 10,2% de la surface du pays et reste globalement représentatif de toute la diversité des écosystèmes de la région. Cependant, ce réseau n'est pas constitué d'écosystèmes intacts car de nombreuses altérations y ont été apportés (certaines espèces sont déjà au seuil critique d'extinction (Addax, gazelle dama, lamantin), voire ont disparu (Rhinocéros noir et blanc, Oryx)) surtout dans les parcs nationaux. Ce qui nous amène à nous interroger sur la dynamique des ressources naturelles et le degré de conservation du parc national de Manda? Une évaluation de la diversité biologique et des ressources hydrographiques de 1951 à 1999 sur la base de la bibliographie existante, de la carte topographique de 1956, des images satellitaires Landsat 5 et 7 TM et ETM+ de 2 périodes (1986, 1999), complétée par des interviews semi-structurés et des transects sur le terrain, permettra de mieux appréhender la dynamique des ressources et les actions de conservation de la biodiversité réalisées à cet effet. Les résultats montrent une dynamique progressive de la faune de 1951 à 1970, puis une dynamique régressive de 1970 à 1989. Après cette tumultueuse période, un repeuplement du parc s'opère de 1989 à 2002. Par contre, la flore est relativement bien conservée avec quelques cours d'eau, des mares, champs et plantations. Et cela grâce aux multiples projets de conservation de la biodiversité. La promotion de l'écotourisme serait une alternative au développement durable de ce parc.

2015-06-01

Women frequently profess happiness about unintended pregnancies; such incongruence is associated with use of less effective contraceptive methods and inconsistent or incorrect method use. Yet, the methods women use may differ from those they desire. Data on 578 women were drawn from a prospective survey of postpartum women aged 18-44 recruited from three hospitals in Texas between 2012 and 2014. Jonckheere-Terpstra tests were used to compare women's feelings about a future pregnancy with their childbearing intentions. Fisher-Freeman-Halton tests compared distributions of contraceptive methods currently used and desired by women who professed happiness about a future unintended pregnancy, as well as distributions of desired methods by women's reported feelings. The proportion of women who reported happiness about a future pregnancy was 59% among those intending to wait two or three years for another child, 46% among those intending to wait four or more years, and 36% among those intending to have no more children. Among women who professed happiness, a greater proportion desired to use a highly effective contraceptive method than were currently using one (72% vs. 15% among those intending no more children; 55% vs. 23% among those intending to wait at least four years; and 36% vs. 10% among those intending to wait two or three years). Across intention categories, the types of methods desired did not differ by whether women professed happiness or unhappiness. Women who profess happiness about a future unintended pregnancy may nonetheless desire highly effective contraceptive methods. Copyright © 2015 by the Guttmacher Institute.

Introduction Les traumatismes du colon sont associés à un risque majeur de complications septiques et de mortalité. Le but de notre étude est d’évaluer les circonstances, la prise en charge, le suivi et les facteurs pronostic de morbidité postopératoire des malades victimes d'un traumatisme colique. Méthodes Il s'agit d'une étude rétrospective sur une série de 49 patients opérés pour des plaies coliques aux services de chirurgie viscérale du CHU HASSAN II de Fès sur une période de 8 ans de juillet 2003 à juillet 2011. Résultats L’âge moyen de nos patients était de 25ans (16-70) avec une nette prédominance masculine (93.8%). Les plaies coliques secondaires à un traumatisme par arme blanche représentent 85% des cas (42 patients), suivi par les plaies iatrogènes au cours d'une coloscopie chez 6 patients (13%), puis les contusions abdominales chez 1 patient (2%). Les parties du cadre colique les plus touchées étaient le colon transverse chez 19 patients (38%) et le colon descendant chez 12 patients (24, 5%). Le colon sigmoïde était le segment le plus touché au cours d'une coloscopie4/6. Quarante-deux patients (85%) ont eu une suture primaire des plaies coliques, six patients (13%) une diversion fécale et un patient (2%) une résection-anastomose. Deux patients (4%) sont décédés suite à un choc septique. La morbidité globale était de 38,7% dominé essentiellement par l'infection de la paroi chez 14 patients et une péritonite post opératoire chez 3 patients. L'analyse univarié a montré une différence significatif en terme d'infection de la paroi entre le groupe colostomie versus suture simple (50% vs 20,9% p<0,05). L'atteinte du colon gauche et la réalisation d'une colostomie sont associés à un risque plus élevés de complications postopératoires. Conclusion La suture primaire peut être effectuée avec un faible taux de complications postopératoire chez la majorité des patients suite à un traumatisme du colon. PMID

LeMYC2 acts as a negative regulator of blue light mediated photomorphogenic growth, and promotes the growth of adult tomato plants

PubMed Central

2014-01-01

Background Arabidopsis ZBF1/MYC2bHLH transcription factor is a repressor of photomorphogenesis, and acts as a point of cross talk in light, abscisic acid (ABA) and jasmonic acid (JA) signaling pathways. MYC2 also functions as a positive regulator of lateral root development and flowering time under long day conditions. However, the function of MYC2 in growth and development remains unknown in crop plants. Results Here, we report the functional analyses of LeMYC2 in tomato (Lycopersicon esculentum). The amino acid sequence of LeMYC2 showed extensive homology with Arabidopsis MYC2, containing the conserved bHLH domain. To study the function of LeMYC2 in tomato, overexpression and RNA interference (RNAi) LeMYC2 tomato transgenic plants were generated. Examination of seedling morphology, physiological responses and light regulated gene expression has revealed that LeMYC2 works as a negative regulator of blue light mediated photomorphogenesis. Furthermore, LeMYC2 specifically binds to the G-box of LeRBCS-3A promoter. Overexpression of LeMYC2 has led to increased root length with more number of lateral roots. The tomato plants overexpressing LeMYC2 have reduced internode distance with more branches, and display the opposite morphology to RNAi transgenic lines. Furthermore, this study shows that LeMYC2 promotes ABA and JA responsiveness. Conclusions Collectively, this study highlights that working in light, ABA and JA signaling pathways LeMYC2 works as an important regulator for growth and development in tomato plants. PMID:24483714

Desires and management preferences of stakeholders regarding feral cats in the Hawaiian islands.

Feral cats are abundant in many parts of the world and a source of conservation conflict. Our goal was to clarify the beliefs and desires held by stakeholders regarding feral cat abundance and management. We measured people's desired abundance of feral cats in the Hawaiian Islands and identified an order of preference for 7 feral cat management techniques. In 2011 we disseminated a survey to 5407 Hawaii residents. Approximately 46% of preidentified stakeholders and 20% of random residents responded to the survey (1510 surveys returned). Results from the potential for conflict index revealed a high level of consensus (86.9% of respondents) that feral cat abundance should be decreased. The 3 most common explanatory variables for respondents' stated desires were enjoyment from seeing feral cats (84%), intrinsic value of feral cats (12%), and threat to native fauna (73%). The frequency with which respondents saw cats and change in the perceived abundance of cats also affected respondent's desired abundance of cats; 41.3% of respondents stated that they saw feral cats daily and 44.7% stated that the cat population had increased in recent years. Other potential environmental impacts of feral cats had little affect on desired abundance. The majority of respondents (78%) supported removing feral cats from the natural environment permanently. Consensus convergence models with data from 1388 respondents who completed the relevant questions showed live capture and lethal injection was the most preferred technique and trap-neuter-release was the least preferred technique for managing feral cats. However, the acceptability of each technique varied among stakeholders. Our results suggest that the majority of Hawaii's residents would like to see effective management that reduces the abundance of feral or free-roaming cats. © 2013 Society for Conservation Biology.

The benefits of rule following: A new account of the evolution of desires.

PubMed

Schulz, Armin W

2013-12-01

A key component of much current research in behavioral ecology, cognitive science, and economics is a model of the mind at least partly based on beliefs and desires. However, despite this prevalence, there are still many open questions concerning both the structure and the applicability of this model. This is especially so when it comes to its 'desire' part: in particular, it is not yet entirely clear when and why we should expect organisms to be desire-based-understood so as to imply that they consult explicit tokenings of what they ought to do-as opposed to being drive-based-understood so as to imply that they react to the world using behavioral reflexes. In this paper, I present the beginnings of an answer to this question. To do this, I start by showing that an influential recent attempt to address these issues-due to Kim Sterelny-fails to be fully successful, as it does not make sufficiently clear what the relative benefits and disadvantages of drive-based and desire-based cognitive architectures are. I then present an alternative account of this matter based on the idea that organisms that can follow explicit behavioral rules (i.e. which have desires) avoid having to memorize a large set of state of the world-action connections-which can (though need not) be adaptive. Finally, I apply this account to the question of what the cognitive value of mental representations should be seen to be; here, I conclude that-contrary to some recent claims-relying on mental representations can make decision making easier, not harder, but also that-in line with these recent claims-whether it does so depends on the details of the case.

Background Consumption of alcohol mixed with energy drinks (AmED) has been associated with a variety of risks beyond that observed with alcohol alone. Consumers of AmED beverages are more likely to engage in heavy episodic (binge) drinking. The purpose of this study was to investigate whether the consumption of high caffeine energy drink mixers with alcohol would increase the desire to drink alcohol compared to the same amount of alcohol alone using a double-blind, within-subjects, placebo-controlled study design. Methods Participants (n = 26) of equal gender who were social drinkers attended 6 double-blind dose administration sessions that involved consumption of alcohol and energy drinks, alone and in combination. On each test day, participants received 1 of 6 possible doses: 1) 1.21 ml/kg vodka + 3.63 ml/kg decaffeinated soft drink, 2) 1.21 ml/kg vodka + 3.63 ml/kg energy drink, 3) 1.21 ml/kg vodka + 6.05 ml/kg energy drink, 4) 3.36 ml/kg decaffeinated soft drink, 5) 3.36 ml/kg energy drink, and 6) 6.05 ml/kg energy drink. Following dose administration, participants repeatedly completed self-reported ratings on the Desire for Drug questionnaire and provided breath alcohol readings. Results Alcohol alone increased the subjective ratings of “desire for more alcohol” compared to placebo doses. Energy drink mixers with the alcohol increased desire for more alcohol ratings beyond that observed with alcohol alone. Conclusions This study provides laboratory evidence that AmED beverages lead to greater desire to drink alcohol versus the same amount of alcohol consumed alone. The findings are consistent with results from animal studies indicating that caffeine increases the rewarding and reinforcing properties of alcohol. PMID:27419377

Research has examined the relationship between religiosity and sexuality but few studies have explored the mechanisms by which sexual variables are influenced by religiosity. The purpose of the present study was to investigate the role of sex guilt in the relationship between religiosity and sexual desire in women. Euro-Canadian (n = 178) and East Asian (n = 361) female university students completed a battery of questionnaires. Higher levels of religious fundamentalism, intrinsic religiosity and spirituality were associated with higher levels of sex guilt in both ethnic groups. Paranormal belief was not associated with sex guilt in either ethnic group. The Euro-Canadian women reported significantly higher levels of sexual desire and significantly less sex guilt than the East Asian women. Among the Euro-Canadian women, sex guilt mediated the relationships between spirituality and sexual desire, and fundamentalism and sexual desire; among the East Asian women, sex guilt mediated the relationships between spirituality and sexual desire, fundamentalism and sexual desire, and intrinsic religiosity and sexual desire. These findings suggest that sex guilt may be one mechanism by which religiosity affects sexual desire among women.

To report the preferences of Fellows of the Australasian College for Emergency Medicine for topics they would desire for their continuing professional development (CPD). A mailed survey of Fellows of the Australasian College for Emergency Medicine asked for Likert type responses on the desirability of CPD on 15 procedural skills, 13 management skills, 11 clinical emergency topics, 9 topics related to teaching, 7 related to diagnostics and 5 evidence based practice topics. CPD in procedural skills of advanced and surgical airways, ED ultrasound, ventilation, skills, plastic procedures and regional anaesthesia were nominated as desirable by 85% of emergency physicians (EP). More than 90% desired CPD in ophthalmological, otorhinolaryngeal, neonatal and paediatric emergencies. Of diagnostic skills, more than 80% considered CPD on computerized tomography, electrocardiography and plain X-ray interpretation as desirable, well as CPD about teaching in general, simulation and preparing candidates for fellowship exams. Of the 12 management skills, 11 were seen as desirable topics by more than 70%, with counter disaster planning, giving feedback and dealing with complaints the most popular. All evidence based practice related skills, including interpreting statistics and undertaking literature searches were seen as desirable topics by more than 80% of EP. This information may assist in the planning of future educational interventions for emergency physicians. EP seek CPD on management, educational and other non clinical skills, as well as topics relating directly to patient care.

Avec le contexte economique actuel dans le domaine des pates et papiers au Canada, l'industrie se doit de diversifier ses produits mis en marche. La fermeture de plus de 20 usines depuis 2005, une baisse du PIB de l'industrie de 1,4 milliard CAD entre 1999--2008, une baisse de la demande de 2,4 %, une diminution du prix de la pate de 20,9 % depuis juillet 2009. La delocalisation du secteur vers l'Asie et l'hemisphere sud sont autant de raisons pour laquelle l'industrie se doit d'etre a l'avant plan de nouvelle technologie a base de fibre de bois. Pour augmenter leur rentabilite, l'industrie se doit de diversifier ses produits dans d'autres secteurs que le simple fabricant de papier impression-ecriture. Sa diversification passe par l'elaboration de nouveaux papiers a valeur ajoutee (papier conducteur, papier bioactif, etc.), par l'utilisation de la biomasse forestiere pour la production d'energie, par l'utilisation de la biomasse forestiere pour l'elaboration d'une plateforme de chimie verte, par l'utilisation de la lignine pour le developpement de polymeres et par l'utilisation de la fibre cellulosique pour la fabrication de nanomateriaux. La fabrication de nanofibrille de cellulose peut devenir un des produits qui servira a diversifier la production des usines de pates et papiers. Les nanofibrilles de cellulose possedent des proprietes mecaniques et chimiques exceptionnelles. Les nanofibrilles de cellulose sont fabriquees a partir d'une oxydation selective de la pate kraft de feuillu avec le systeme TEMPO-NaOCl-NaBr. L'oxydation selective de l'alcool primaire en C6 du monomere de glucose sous forme de carboxylates engendre une modification chimique de la cellulose qui accroit l'hydrophilicite des fibrilles. Suite a cette oxydation, nous devons effectuer une desintegration mecanique de la fibre kraft de feuillu oxydee pour separer les fibrilles. Le processus d'oxydation de la fibre par le systeme TEMPO-NaOCl-NaBr et sa defibrillation par la suite engendre une

There are many variables that can affect lithographic dependent device yield. Because of this, it is not enough to make optical proximity corrections (OPC) based on the mask type, wavelength, lens, illumination-type and coherence. Resist chemistry and physics along with substrate, exposure, and all post-exposure processing must be considered too. Only a holistic approach to finding imaging solutions will accelerate yield and maximize performance. Since experiments are too costly in both time and money, accomplishing this takes massive amounts of accurate simulation capability. Our solution is to create a workbench that has a set of advanced user applications that utilize best-in-class simulator engines for solving litho-related DFM problems using distributive computing. Our product, ProLE (Programmable Lithography Engine), is an integrated system that combines Petersen Advanced Lithography Inc."s (PAL"s) proprietary applications and cluster management software wrapped around commercial software engines, along with optional commercial hardware and software. It uses the most rigorous lithography simulation engines to solve deep sub-wavelength imaging problems accurately and at speeds that are several orders of magnitude faster than current methods. Specifically, ProLE uses full vector thin-mask aerial image models or when needed, full across source 3D electromagnetic field simulation to make accurate aerial image predictions along with calibrated resist models;. The ProLE workstation from Petersen Advanced Lithography, Inc., is the first commercial product that makes it possible to do these intensive calculations at a fraction of a time previously available thus significantly reducing time to market for advance technology devices. In this work, ProLE is introduced, through model comparison to show why vector imaging and rigorous resist models work better than other less rigorous models, then some applications of that use our distributive computing solution are shown

Little is known about non-monosexual women's sexual arousal and desire. Typically, bisexual women have been excluded from research on sexual arousal and desire, whereas mostly heterosexual and mostly lesbian women have been placed into monosexual categories. This research (1) compared the subjective sexual arousal and desire of self-identified heterosexual, mostly heterosexual, bisexual, mostly lesbian, and lesbian women in partnered sexual activities with men and with women, and (2) compared within-group differences for subjective sexual arousal and desire with men versus women for the five groups. Participants included 388 women (M age = 24.40, SD = 6.40, 188 heterosexual, 53 mostly heterosexual, 64 bisexual, 32 mostly lesbian, 51 lesbian) who filled out the Sexual Arousal and Desire Inventory (SADI). Sexual orientation was associated with sexual arousal and desire in sexual activities with both men and with women. Bisexuals reported higher sexual arousal and desire for women than heterosexuals and lesbians, while lesbians reported lower sexual arousal and desire with men than the other groups. Heterosexuals and mostly heterosexuals scored higher on the male than on the female motivational dimension of the SADI, while the reverse was found for lesbians and mostly lesbians. Findings indicate that non-monosexuals have higher sexual arousal and desire in sexual activities with women than monosexuals. Further, bisexual women did not differentiate their sexual arousal with men versus women, while the other sexual orientation groups differentiated in terms of their motivation to engage in sexual activity. These findings may have implications for how female sexual orientation is conceptualized.

People generally hold positive stereotypes of physically attractive people and because of those stereotypes often treat them more favorably. However, we propose that some beliefs about attractive people, specifically, the perception that attractive individuals have a greater sense of entitlement than less attractive individuals, can result in negative treatment of attractive people. We examine this in the context of job selection and propose that for relatively less desirable jobs, attractive candidates will be discriminated against. We argue that the ascribed sense of entitlement to good outcomes leads to perceptions that attractive individuals are more likely to be dissatisfied working in relatively less desirable jobs. When selecting candidates for relatively less desirable jobs, decision makers try to ascertain whether a candidate would be satisfied in those jobs, and the stereotype of attractive individuals feeling entitled to good outcomes makes decision makers judge attractive candidates as more likely to be dissatisfied in relatively less (but not more) desirable jobs. Consequently, attractive candidates are discriminated against in the selection for relatively less desirable jobs. Four experiments found support for this theory. Our results suggest that different discriminatory processes operate when decision makers select among candidates for relatively less desirable jobs and that attractive people might be systematically discriminated against in a segment of the workforce.

Background: Sexual function and activity in old age have been inadequately studied world over. It is important to know that aging processes are not confined to persons beyond the age of 60 years; many changes in elderly have their antecedents in the middle age. Aims: This study sought to determine the patterns of sexual activity and function in individuals over 50 years of age. It also sought to discuss barriers such as chronic illness that may interfere with sexual function. Materials and Methods: We conducted a study of subjects above the age of 50 years in various outpatient departments (OPDs) of a teaching municipal hospital in Mumbai, by interviewing 60 individuals who attended the OPDs, after taking their informed consent. Socio-demographic and other information on their sexual function and activities were obtained. Data was analyzed using statistical package for social sciences v15. Results: 72% individuals below 60 were sexually active, while only 57% above 60 were active. Others had become completely abstinent at some time in their lives. Statistical analysis revealed significant gender, health and educational status based differences in the sample. Conclusion: Our study showed significant presence of sexual desire, activity and function even after the age of 50 years; a decline by the age of 60 and above was a finding that reflected more in women. Chronic illness did affect sexual function and desire. PMID:22303037
