Several personality models are known for being replicable across cultures, such as the Five-Factor Model (FFM) or Eysenck's Psychoticism-Extraversion-Neuroticism (PEN) model, and are for this reason considered universal. The aim of the current study was to evaluate the cross-cultural replicability of the recently revised Alternative FFM (AFFM). A total of 15048 participants from 23 cultures completed the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) aimed at assessing personality according to this revised AFFM. Internal consistencies, gender differences and correlations with age were similar across cultures for all five factors and facet scales. The AFFM structure was very similar across samples and can be considered as highly replicable with total congruence coefficients ranging from .94 to .99. Measurement invariance across cultures was assessed using multi-group confirmatory factor analyses, and each higher-order personality factor did reach configural and metric invariance. Scalar invariance was never reached, which implies that culture-specific norms should be considered. The underlying structure of the ZKA-PQ replicates well across cultures, suggesting that this questionnaire can be used in a large diversity of cultures and that the AFFM might be as universal as the FFM or the PEN model. This suggests that more research is needed to identify and define an integrative framework underlying these personality models. © 2016 European Association of Personality Psychology. [less ▲]

Pain physiology education is an important component in the management of patients with chronic musculoskeletal pain. The Neurophysiology of Pain Questionnaire (NPQ) was developed in English to assess pain physiology knowledge in patients. This study aimed to translate the NPQ into French (NPQ-Fr) and to investigate the main psychometric properties of the NPQ-Fr. The translation was performed using the best practice translation guidelines. One hundred and one French-speaking patients with chronic non-specific spinal pain completed the NPQ-Fr to assess its acceptability and presence of floor/ceiling effects and test its dimensionality. The construct validity was tested by comparing the patients’ NPQ-Fr scores to those of 17 physiotherapists and investigating its correlation with subscales of the Short Form-36 questionnaire. The reliability (i.e., internal consistency and testretest reliability) was also investigated. To test the test-retest reliability, 70 patients were asked to complete the NPQ-Fr twice with one week in between. Regarding the NPQ-Fr psychometric properties: 1) acceptability was good; 2) internal consistency reached a Cronbach α-coefficient of 0.44; 3) no floor and ceiling effects were observed in patients; 4) a principal factor analysis generated three major factors; 5) construct validity was good; and 6) reliability was acceptable (intraclass correlation coefficient = 0.644; standard error of measurement = 1.5). The NPQ-Fr has satisfactory basic psychometric properties in patients with chronic spinal pain. [less ▲]

Studies of sexuality in Caribbean culture are on the rise, focusing mainly on homosexuality and homophobia or on regional manifestations of normative and nonnormative sexualities. The Cross-Dressed Caribbean extends this exploration by using the trope of transvestism not only to analyze texts and contexts from anglophone, francophone, Spanish, Dutch, and diasporic Caribbean literature and film, but also to highlight reinventions of sexuality and resistance to different forms of exploitation and oppression.

We propose in this paper a novel approach for identifying rare events that may endanger power system integrity. This approach is inspired by the rare-event simulation literature and, in particular, by the cross-entropy (CE) method for rare event simulation. We propose a general framework for exploiting the CE method in the context of power system reliability evaluation, when a severity function defined on the set of possible events is available. The approach is illustrated on the IEEE 30 bus test system when instability mechanisms related to static voltage security are considered. [less ▲]

This paper introduces an algorithm for direct search of control policies in continuous-state, discrete-action Markov decision processes. The algorithm looks for the best closed-loop policy that can be represented using a given number of basis functions (BFs), where a discrete action is assigned to each BF. The type of the BFs and their number are specified in advance and determine the complexity of the representation. Considerable flexibility is achieved by optimizing the locations and shapes of the BFs, together with the action assignments. The optimization is carried out with the cross-entropy method and evaluates the policies by their empirical return from a representative set of initial states. The return for each representative state is estimated using Monte Carlo simulations. The resulting algorithm for crossentropy policy search with adaptive BFs is extensively evaluated in problems with two to six state variables, for which it reliably obtains good policies with only a small number of BFs. In these experiments, cross-entropy policy search requires vastly fewer BFs than value-function techniques with equidistant BFs, and outperforms policy search with a competing optimization algorithm called DIRECT.

Over the last decade, polymer micelles attracted an increasing interest in drug pharmaceutical research because they could be used as efficient drug delivery systems. Micelles of amphiphilic block copolymers are supramolecular core-shell type assemblies of tens of nanometers in diameter. In principle, the micelles core is usually constructed with biodegradable hydrophobic polymers such as aliphatic polyesters, e.g. poly(ɛ-caprolactone) (PCL), which serves as a reservoir for the incorporation of various lipophilic drugs. Water soluble poly(ethylene oxide) (PEO) is most frequently used to build the micelle corona because it is very efficient in preventing protein adsorption at surfaces and in stabilizing the micelles in the blood compartment, giving rise to particles invisible to the body defence system (so-called stealthy or long circulating particles). The tumour targeting of a cytotoxic agent refers to the passive accumulation of polymer nanocarriers to solid tumours (EPR effect) followed by active internalization in tumor cells. The internalization of the drug is required for cell death because most cytotoxic drugs act intracellularly. Accordingly, polymer micelles are usually modified by specific ligands. No-specific ligands can be used if their exposition is modulated by the pH decrease typical of tumour tissues. The release of the drug is ruled by diffusion and degradation of the biodegradable polymer used as reservoir. Even if micelles get a high stability in aqueous media thanks to their low critical micellar concentration, the dissociation of micelles is not always preserved when they are injected in the blood compartment. The cross-linking of the core of micelles by disulfide bridges will provide the stability of micelles after the administration and will release the drugs intracellularly by enzymatic breaking of disulfide bridges. This work consists in the development of new macromolecular architectures for the targeting of tumour cells. pH sensitive copolymers able to micellize so as non-specific ligand like biotin is exposed on their surface in response to pH decrease typical for tumour tissues will be synthesized by the incorporation of pH-sensitive linkers, e.g. imine benzoïc linkers. In addition, the core of these new micelles will be cross-linked by disulfide bridges to prevent dissociation around healthy cells and trigger the drug release inside tumour cells. [less ▲]

In the pharmaceutical field, amphiphilic block copolymers are of great interest for the nanovectorization of active principles in Drug Delivery. Indeed, new drugs are synthesized each day but in too many cases, their high hydrophobicity makes them useless because of the absence of an appropriated administration method. Typically, amphiphilic block copolymers present the remarkable property to self-assemble in water with formation, in most cases, of spherical micelles characterized by a hydrophobic core and a hydrophylic corona. Rapidly, their ability to encapsulate a hydrophobic drug in their hydrophiobic core was investigated to increase the solubility of the drug in aqueous media, prevent its degradation and decrease its toxicity. However, polymer micelles suffer of the main drawback to be unstable in diluted medium, leading to a premature release of the drug, when the concentration falls down the critical micellar concentration (CMC), which it is rapidly observed after intravenous injection. This work aims at reporting on the development of a drug delivery device based on a new amphiphilic block copolymers made of degradable polyphosphate and bioeliminable poly(ethylene oxide). Thanks to their biocompatibility, biodegradability and their structure similar to natural biomacromolecules, polyphosphates are appealing polymers for biomedical applications. In contrast to aliphatic polyesters, polyphosphate properties and functionality are easily tuned via the chemical nature of the lateral chains R. In order to get rid of the CMC, the crosslinking of the micelle’s core was realized by UV radiation, in order to fulfill the increasingly stringent requirements of biomedical applications. For this purpose, photo-cross-linkable groups were introduced on the polyphosphate backbone. The effect of the crosslinking rate on the drug loading and the drug release was evaluated using doxorubicin as model drug. [less ▲]

Recent studies suggest common neural substrates involved in verbal and visual working memory (WM), interpreted as reflecting shared attention-based, short-term retention mechanisms. We used a machine-learning approach to determine more directly the extent to which common neural patterns characterize retention in verbal WM and visual WM. Verbal WM was assessed via a standard delayed probe recognition task for letter sequences of variable length. Visual WM was assessed via a visual array WM task involving the maintenance of variable amounts of visual information in the focus of attention. We trained a classifier to distinguish neural activation patterns associated with high- and low-visual WM load and tested the ability of this classifier to predict verbal WM load (high–low) from their associated neural activation patterns, and vice versa. We observed significant between-task prediction of load effects during WM maintenance, in posterior parietal and superior frontal regions of the dorsal attention network; in contrast, between-task prediction in sensory processing cortices was restricted to the encoding stage. Furthermore, between-task prediction of load effects was strongest in those participants presenting the highest capacity for the visual WM task. This study provides novel evidence for common, attention-based neural patterns supporting verbal and visual WM. [less ▲]
