Authors: Ngom Papa Ibrahima , Attebi Pascaline , Diouf Joseph Samba , Diop Ba Khady , Badiane Alpha , Diagne Falou 
Published: November 2013

Le PIDAQ (Psychosocial Impact of Dental Aesthetics Questionnaire) est un
instrument qui a été mis au point pour évaluer l’impact des dysmorphoses orthodontiques
sur la qualité de vie. L’objectif de cette étude était d’adapter en langue française le
questionnaire PIDAQ. Secondairement, une évaluation de ses propriétés psychométriques et
de sa validité a été mise en œuvre. Les recommandations de Guillemin, et
al. (1993) ont servi de base dans cette perspective. En particulier, les quatre
étapes suivantes sont rigoureusement suivies : étape préparatoire, réunion d’expert,
rétro-traduction et harmonisation. La version en français obtenue à la fin du processus
d’adaptation, que nous avons convenu de nommer QIPEO, est testée sur un échantillon de 42
sujets (33 femmes et 9 hommes) âgés de 24,60 ± 8,66 ans. Les résultats montrent une
excellente fiabilité du PIDAQ avec une cohérence interne des items qui constituent chacun
des domaines variant de 0,67 pour les « préoccupations esthétiques » à 0,87 pour l’« impact
social ». La reproductibilité des réponses données par 14 patients à deux évaluations
différentes séparées de 15 jours est bonne pour les quatre domaines avec un coefficient
intra-classe allant de 0,72 pour l’« impact social » à 0,90 pour la « perception esthétique ».
Cette étude révèle aussi que le PIDAQ a un certain degré de validité pour cette
population, les scores étant, d’une part, associés de façon significative à la perception
qu’ont les patients de l’alignement de leurs dents et, d’autre part, avec la composante de
santé dentaire de l’IOTN (Index of Orthodontic Treatment Need). Une étude
de validation sur un échantillon plus grand et plus variée de sujets issus d’une
population française est recommandée ainsi qu’une analyse de sa réactivité aux changements
(traitement, récidives, etc.).

Broad-scale phylogenomics provides insights into retrovirus–host evolution
Authors: Hayward Alexander , Grabherr Manfred , Jern Patric 
Published: November 2013

Significance
Retroviruses, such as HIV, are important pathogens of vertebrates, including humans. They are capable of crossing species barriers to infect new hosts, but knowledge about the evolutionary history of retroviruses is limited. However, genomic traces of past retrovirus activities known as “endogenous retroviruses” can be screened from sequenced genomes and analyzed to improve understanding of retrovirus evolution. Here we use a unique approach to address the evolution of one group of retroviruses in a screen of 60 diverse vertebrate host genomes. We find evidence of rampant host-switching across mammalian orders by members of this group throughout their evolutionary history. We also find evidence that the spread of infective retroviruses from this group may be facilitated by rats.
In situ structure and dynamics of DNA origami determined through molecular dynamics simulations
Authors: Yoo Jejoong , Aksimentiev Aleksei 
Published: November 2013

Significance
Folding of DNA strands into complex three-dimensional nanoscale objects—DNA origami—has emerged as a new paradigm for practical nanotechnology. Although computer-aided design tools are often used to illustrate the idealized shape of such objects, their structural behavior in solution has been poorly characterized. Using a large supercomputer system, we created trajectories of millions of atoms to obtain the first atomically precise portrait of DNA origami in solution. The DNA origami objects were found to undergo considerable structural fluctuations, significantly departing from their idealized conformations at the nanometer scale. Analysis of the fluctuations provided a detailed map of local mechanical properties of DNA origami. Our work demonstrates the potential for atomistic simulations to facilitate rational engineering of DNA origami objects.
Microbial biogeography of wine grapes is conditioned by cultivar, vintage, and climate
Authors: Bokulich Nicholas A. , Thorngate John H. , Richardson Paul M. , Mills David A. 
Published: November 2013

SignificanceWe demonstrate that grape-associated microbial biogeography is nonrandomly associated with regional, varietal, and climatic factors across multiscale viticultural zones. This poses a paradigm shift in our understanding of food and agricultural systems beyond grape and wine production, wherein patterning of whole microbial communities associated with agricultural products may associate with downstream quality characteristics. Elucidating the relationship between production region, climate, and microbial patterns may enhance biological control within these systems, improving the supply, consumer acceptance, and economic value of important agricultural commodities.

Significance
Found in most eukaryotic cells, a centriole is a cylindrically shaped subcellular structure that plays an important role in various cellular processes, including mitotic spindle formation and chromosome segregation. Centriole duplication occurs only once per cell cycle, thus ensuring accurate control of centriole numbers to maintain genomic integrity. Although a growing body of evidence suggests that a Ser/Thr protein kinase, polo-like kinase 4 (Plk4), is a key regulator of centriole duplication, how Plk4 is recruited to centrosomes remains largely unknown. Here we showed that Plk4 dynamically localizes to distinct subcentrosomal regions by interacting with two hierarchically regulated scaffolds, Cep192 and Cep152. Highlighting the importance of these interactions, mutational disruption of either one of these interactions was sufficient to cripple Plk4-dependent centriole biogenesis.
Orexin/hypocretin system modulates amygdala-dependent threat learning through the locus coeruleus
Authors: Sears Robert M. , Fink Ann E. , Wigestrand Mattis B. , Farb Claudia R. , de Lecea Luis , LeDoux Joseph E. 
Published: November 2013

SignificanceThe hypothalamic orexin (hypocretin) system controls survival-related processes such as food intake, arousal, and stress. Here we show that orexins also play an important role in learning about stimuli that predict harm. We demonstrate that blocking orexin activity in the noradrenergic locus coeruelus (LC) reduces, whereas increasing its activity enhances, threat learning in a Pavlovian auditory threat conditioning paradigm. Moreover, we demonstrate a direct functional connection between orexin enhancement of LC activity and amygdala-dependent memory processes. Strong, aversive memories can lead to fear and anxiety disorders that have a negative impact on individuals and their quality of life. The orexin system may represent a unique treatment target for these disorders.
Breast Tissue Expander—Related Infections: Perioperative Antimicrobial Regimens
Authors: Viola George M. , Raad Issam I. , Rolston Kenneth V. 
Published: November 2013

Objective.The rate of postmastectomy tissue expander (TE) infection remains excessively high, ranging between 2% and 24%. We hypothesized that current perioperative antimicrobial regimens utilized for breast TE reconstruction may be outdated as a result of recent changes in microflora and susceptibility patterns.Design and Methods.We reviewed the records of all patients who had a TE reconstructive procedure and developed a definite breast TE infection between 2003 and 2010 at MD Anderson Cancer Center. Antimicrobials were stratified into 3 groups: systemic perioperative, local irrigation, and oral immediate postoperative antimicrobials. These were considered discordant if they did not target the isolated organisms, while a breakthrough infection was defined as an infection that occurred despite concordant antimicrobial coverage.Results.Overall, 75 patients with a definite TE infection were identified. The most common organisms identified were methicillin-resistant Staphylococcus epidermidis (29%), methicillin-resistant Staphylococcus aureus (15%), and gram-negative rods (26%). The use of systemic perioperative antimicrobials was deemed discordant in 51% of the cases. Although 79% of the patients received broad-spectrum perioperative local antimicrobial irrigation, 63% developed a breakthrough infection. Even though 61% received oral postoperative prophylactic antimicrobials, 63% of the times they were deemed discordant.Conclusions.Contrary to the proven effectiveness of a single dose of perioperative antibiotics, the common use of local antimicrobial irrigation and prolonged postoperative oral antibiotics appears to be an inadequate component of our preventive armamentarium. Also, because methicillin-resistant staphylococcal and pseudomonal infections occurred approximately 60% of the time, at institutions that have observed an increase of these organisms, it may be prudent that perioperative antimicrobials target these microorganisms.
A novel treatment resource for co-occurring symptoms
Authors: L. McCallum Stacey , A. Mikocka-Walus Antonina , Keage Hannah , Churches Owen , Andrews Jane 
Published: November 2013

Purpose
– This paper describes the development of a novel integrative self-directed treatment tool which uses cognitive behavioural therapy techniques to reduce anxiety symptoms in patients presenting to treatment for alcohol-related problems. More specifically, the purpose of this paper is to explore patient and health practitioner perceptions of the booklet, in order to determine its suitability and utility in the context of existing alcohol treatment services. The extent of cross-informant agreement between patient and health practitioner responses is also examined.

Design/methodology/approach
– This research utilises a cross-sectional qualitative research design using semi-structured interview methods with patients presenting to hospital for alcohol-related diseases/illnesses/accidents/injuries (n=15) and practitioners (n=10) working at inpatient, outpatient and residential substance treatment facilities.

Findings
– The present study found that the majority of patients (80 per cent) and practitioners (90 per cent) expressed a motivation to utilise the proposed booklet, agreeing that the booklet was a practical, achievable and educational resource for patients suffering from co-occurring anxiety symptoms in substance abuse facilities. Participants outlined limitations of the resource, suggesting that the booklet would be most suitable for patients with moderate to high cognitive ability, who also exhibit a motivation to change alcohol consumption and have access to additional support.

Practical implications
– Findings from the present study suggest that the booklet may be most effective in improving treatment accessibility and patient treatment seeking behaviours; rather than reducing practitioner-patient contact.

Originality/value
– This paper focuses on the development and utility of a novel resource suitable for substance abuse treatment facilities. The findings and feedback produced from the present study can assist with modifications of the intervention and in improving the effectiveness of future trials.
National identity and the perceived values of foreign products with local brands
Authors: Le Nguyen-Hau , Thi Nguyen Hai-Minh , Van Nguyen Tuan 
Published: November 2013

Purpose
– Based on the intra-national diversity view, this research aims to employ the concept of national identity to explain the consumer's evaluation of foreign product with local brand and the extent of consumer ethnocentrism. It then investigates how product evaluation and consumer ethnocentrism are capable of explaining consumer's perceived value of the product. Finally, it tests the impact of consumer perceived value on consumer willingness to buy.

Design/methodology/approach
– A sample of 251 consumers of local wine in Vietnam was analysed using structural equation modelling technique.

Findings
– National identity has positive impacts on product evaluation and consumer ethnocentrism. These two factors together can explain 58 percent variance of consumer's perceived value, which is the key predictor of willingness to buy. Additionally, emotional and social values are found to be important motivators of local wine consumption in Vietnam.

Research limitations/implications
– The three reflective first-order components of national identity might be alternatively modelled as formative ones. Moderating effect of consumption occasions, consumer knowledge and other social demographics should be investigated. Finally, to compare Vietnamese consumers towards local wine vs foreign wine.

Originality/value
– Among very few empirical studies about the effects of national identity on consumer's value of foreign product with local brand under a mixed effects of the perceived inferior quality of locally made product and status-oriented consumption behavior, via the full mediation of product evaluation and consumer ethnocentrism. This study also suggests a conceptual distinction between ethnocentrism and consumer ethnocentrism in studies of national identity.
The impacts of production uncertainties on world food prices
Authors: Meyer Stefan , Yu Xiaohua 
Published: November 2013

Purpose
– Because of large time lags between the production decision, completion and sale of output, any uncertainty during the process of production, such as bad weather, disease or financial crisis, can affect the prices within food markets systematically. Therefore, the paper aims to analyze the influence of production uncertainties on world's wheat and corn prices.

Design/methodology/approach
– In a specially designed two-step method, at first, the contributions of deterministic and uncertainty factors to wheat and corn production in around 100 countries are decomposed. Then, a panel model is applied to estimate the combined impact of each type of factors on the prices. Furthermore, the authors decompose the explained variances of the panel models in order to determine the importance of each type of factors for price adjustments.

Findings
– The uncertainties in wheat production do significantly affect both wheat and corn prices on a global scale, whilst those of corn do not. Moreover, the variance decompositions reveal that deterministic factors contribute much more to the explanation of world food prices than indeterministic factors.

Practical implications
– As deterministic factors are much more important than uncertainty factors for explaining market price movements, farmers should organize themselves to coordinate production in order to stabilize world food prices.

Originality/value
– The paper proposes a simple methodology, which enables scholars to integrate production uncertainties into food price analyses.
“The experiences of professionals working with homeless people in a clinical setting”: a qualitative study
Authors: Arslan Serdar 
Published: November 2013

Purpose
– The purpose of this paper is to describe a qualitative study using an idiographic approach to explore professionals’ experience of working with homeless people. The paper took account of the approaches taken by these professionals and the perceived affects and influences inherent in their work.

Design/methodology/approach
– The paper used semi-structured interviews and an interpretative phenomenological analysis methodology to explore the professionals’ experience of working with homeless people, with a sample of ten participants (professionals) working within the field.

Findings
– Three major themes emerged: helplessness; awareness of early traumas; and frustration at the response of mainstream mental health services. These findings support the view that a specialised personality disorder clinic would help professionals to refer complex cases to mental health services for a comprehensive package of support and care.

Originality/value
– There is limited research into the emotions of professionals working in a difficult clinical settings associated with homeless clients. The paper will help clinicians, health professionals and commissioners identify the coping skills and the resources and tools to support the needs and demands of these service users.

Findings
– Reveals that employers need two policies to manage risks associated with the use of social media; a policy covering business use of social media and another covering employees' personal use of social media.

Practical implications
– Guides managers in assessing the exposure of their organizations and clients to the risks identified.

Originality/value
– Raises the issue of organizational awareness and preparedness to undertake challenges posed by social media.
The eight imperatives of effective adult learning
Authors: Longenecker Clinton , Abernathy Rob 
Published: November 2013

Purpose
– Advances the view that those responsible for leading adult learning and performance improvement needs to take into account how adults truly learn.

Design/methodology/approach
– Lays out eight imperatives – based on the authors' research and experience with adult learners – which must be taken into consideration when designing, implementing and assessing adult-learning experiences in the modern workplace.

Findings
– Lists these imperatives as: relevance, importance and utility are paramount; hubris and ego can roadblock learning; the credibility of the information source is important; never underestimate the importance of clear learning objectives; adults learn by engagement and doing; accountability for learning is critical; adult learners need coaching and feedback; and plan to stave off learning distractions.

Practical implications
– Aims to get trainers to think through the specific things that can help to increase and accelerate learning across the spectrum of adult-learning opportunities in the modern workplace.

Originality/value
– Claims that, when leaders incorporate these imperatives in their learning initiatives, learning is more productive and the likelihood of a good return-on-investment rises. When these imperatives are ignored or not taken seriously, time, talent and treasure are wasted and leaders risk damaging their own credibility.
