Blue and white light emission from zinc oxide nanoforests
Authors: Noor Nafisa , Lucera Luca , Capuano Thomas , Manthina Venkata , Agrios Alexander G , Silva Helena , Gokirmak Ali
Published: December 2015

Blue and white light emission is observed when high voltage stress is applied using micrometer-separated tungsten probes across a nanoforest formed of ZnO nanorods. The optical spectrum of the emitted light consistently shows three fine peaks with very high amplitude in the 465–485 nm (blue) range, corresponding to atomic transitions of zinc. Additional peaks with smaller amplitudes in the 330–650 nm range and broad spectrum white light is observed depending on the excitation conditions. The spatial and spectral distribution of the emitted light, with pink–orange regions identifying percolation paths in some cases and high intensity blue and white light with center to edge variations in others, indicate that multiple mechanisms lead to light emission. Under certain conditions, the tungsten probe tips used to make electrical contact with the ZnO structures melt during the excitation, indicating that the local temperature can exceed 3422 °C, which is the melting temperature of tungsten. The distinct and narrow peaks in the optical spectra and the abrupt increase in current at high electric fields suggest that a plasma is formed by application of the electrical bias, giving rise to light emission via atomic transitions in gaseous zinc and oxygen. The broad spectrum, white light emission is possibly due to the free electron transitions in the plasma and blackbody radiation from molten silicon. The white light may also arise from the recombination through multiple defect levels in ZnO or due to the optical excitation from solid ZnO. The electrical measurements performed at different ambient pressures result in light emission with distinguishable differences in the emission properties and I–V curves, which also indicate that the dielectric breakdown of ZnO, sublimation, and plasma formation processes are the underlying mechanisms.

Published: December 2015

The development of low energy cost membranes to separate He from noble gas mixtures is highly desired. In this work, we studied He purification using recently experimentally realized, two-dimensional stanene (2D Sn) and decorated 2D Sn (SnH and SnF) honeycomb lattices by density functional theory calculations. To increase the permeability of noble gases through pristine 2D Sn at room temperature (298 K), two practical strategies (i.e., the application of strain and functionalization) are proposed. With their high concentration of large pores, 2D Sn-based membrane materials demonstrate excellent helium purification and can serve as a superior membrane over traditionally used, porous materials. In addition, the separation performance of these 2D Sn-based membrane materials can be significantly tuned by application of strain to optimize the He purification properties by taking both diffusion and selectivity into account. Our results are the first calculations of He separation in a defect-free honeycomb lattice, highlighting new interesting materials for helium separation for future experimental validation.

Residential real estate assumes crucial importance in a country's socioeconomic development. It is an important field of study, and much work has gone into better understanding the sector and the factors determining sales within it, such as time-on-the-market (TOM). TOM can be influenced by a variety of elements; a fact that in effect raises a lot of issues, because these determinants are often interpreted in an ambiguous or unstructured way. This study aims to bring greater accuracy and structure to our understanding of these factors, by showing that the integrated use of cognitive mapping with the Analytic Hierarchy Process (AHP) can give rise to a conceptually coherent and empirically valid framework to calculate TOM indices in the residential real estate market. Because it takes into account both tangible and intangible characteristics of a house, this measurement framework also boosts strategic planning support and allows for more informed business planning, which we believe can be a real contribution to the development of the real estate market. The practical implications and limitations of this evaluation system are also discussed.
IDENTIFYING DETERMINANTS OF DEMAND FOR CONSTRUCTION USING AN ECONOMETRIC APPROACH
Authors: JIANG Heng , LIU Chunlu
Published: December 2015

Economic variation and its effects on construction demand have received a great deal of attention in construction economics studies. An understanding of future trends in demand for construction could influence investment strategies for a variety of parties, including construction developers, suppliers, property investors and financial institutions. This paper derives the determinants of demand for construction in Australia using an econometric approach to identify and evaluate economic indicators that affect construction demand. The forecasting contribution of different determinants of economic indicators and their categories to the demand for construction are further estimated. The results of this empirical study suggest that changes in consumer's expectation, income and production, and demography and labour force are closely correlated with the movement of construction demand; and 14 economic indicators are identified as the determinants for construction demand. It was found that the changes in construction price, national income, size of population, unemployment rate, value or export, household expenditure and interest rates play key roles in explaining future variations in the demand for construction in Australia. Some “popular” macroeconomic indicators, such as GDP, established house price and bank loans produced inconclusive results.
MEASURING THE EFFECTS OF MERGERS AND ACQUISITIONS ON THE ECONOMIC PERFORMANCE OF REAL ESTATE DEVELOPERS
Authors: JIN Zhigang , XIA Bo , LI Vera , LI Heng , SKITMORE Martin
Published: December 2015

Real estate developers in China are using mergers and acquisitions (M&As) to ensure their survival and competitiveness. However, no suitable method is yet available to assess whether such M&As provide enhanced value for those involved. Using a hybrid method of data envelopment analysis (DEA) and Malmquist total factor productivity (TFP) indices, this paper evaluates the short and medium term effects of M&As on acquirers’ economic performance with a set of 32 M&A cases occurring during 2000–2011 in China. The results of the analysis show that M&As generally have a positive effect on acquirers’ economic performance. Acquisitions on average experienced a steady growth in developer Malmquist TFP, a more progressive adoption of technology immediately after acquisition, a slight short-term decrease in technical efficiency after acquisition but followed by a marked increase in the longer term once the integration and synergy benefits were realised. However, there is no evidence to show whether developers achieved any short or long term scale efficiency improvements after M&A. The findings of this study provide useful insights on developer M&A performance from an efficiency and productivity perspective.
SOLAR METALLICITY DERIVED FROM IN SITU SOLAR WIND COMPOSITION
Authors: von Steiger R. , Zurbuchen T. H.
Published: December 2015

We use recently released solar wind compositional data to determine the metallicity of the Sun—the fraction per unit mass that is composed of elements heavier than He. We focus on a present-day solar sample available to us, which is the least fractionated solar wind from coronal holes near the poles of the Sun. Using these data, we derive a metallicity of Z = 0.0196 ± 0.0014, which is significantly larger than recent published values based on photospheric spectroscopy, but consistent with results from helioseismology.
DOPPLER SHIFT OF THE QUIET REGION MEASURED BY MERIDIONAL SCANS WITH THE EUV IMAGING SPECTROMETER ON BOARD HINODE
Authors: Kitagawa N. , Hara H. , Yokoyama T.
Published: December 2015

Spatially averaged (

) EUV spectral lines in the transition region of solar quiet regions are known to be redshifted. Because the mechanism underlying this phenomenon is unclear, we require additional physical information on the lower corona in order to limit the theoretical models. To acquire this information, we measured the Doppler shifts over a wide coronal temperature range (

–6.3) using the spectroscopic data taken by the Hinode EUV Imaging Spectrometer. By analyzing the data over the center-to-limb variations covering the meridian from the south to the north pole, we successfully measured the velocity to an accuracy of 3

the Doppler shifts of the emission lines were almost zero with an error of 1–3

We present a study of stellar populations in a sample of spectroscopically confirmed Lyman-break galaxies (LBGs) and Lyα emitters (LAEs) at

These galaxies have deep images from Subaru, the Hubble Space Telescope, and Spitzer/IRAC. We focus on 27 galaxies with IRAC detections, and characterize their stellar populations based on the multi-band data and secure redshifts. By estimating nebular emission from the observed Lyα flux, we break the strong model degeneracy between young galaxies with prominent nebular emission and older galaxies with strong Balmer breaks. The results show that our galaxies cover a wide range of ages from several to a few hundred million years (Myr), and stellar masses from ∼108 to ∼10

These galaxies can be roughly divided into two subsamples: an “old” subsample consisting of galaxies older than 100 Myr, with stellar masses higher than

and a “young” subsample consisting of galaxies younger than ∼30 Myr, with masses ranging between ∼108 and ∼

Both subsamples display a correlation between stellar mass and star formation rate (SFR), but with very different normalizations. The average specific SFR (sSFR) of the “old” subsample is 3–4 Gyr−1, consistent with previous studies of “normal” star-forming galaxies at

The average sSFR of the “young” subsample is an order of magnitude higher, likely due to starburst activity. Our results also indicate little dust extinction in the majority of the galaxies, as already suggested by their steep rest-frame UV slopes. Finally, LAEs and LBGs with strong Lyα emission are indistinguishable in terms of age, stellar mass, and SFR.

Principale science fondamentale de la santé publique, l’épidémiologie traite des problèmes de santé des populations. Elle s’appuie essentiellement sur trois approches : descriptive, analytique ou explicative, et évaluative ou d’intervention. L’épidémiologie du handicap est, pour cette discipline, la déclinaison des évolutions majeures de la conception de la santé, au cours du siècle dernier. La transformation du paysage sanitaire accompagnant les transitions épidémiologique, avec la place des maladies chroniques, et démographique, avec le vieillissement de la population, a déplacé ses préoccupations des causes vers les conséquences des problèmes de santé. Le travail d’élaboration internationale d’un langage commun, effectué dans le cadre des classifications internationales de l’ oms , et le développement de grandes enquêtes populationnelles dans différents pays ont constitué des prérequis à l’étude du handicap au niveau des populations. Son objet d’étude n’est plus la maladie mais les activités et le fonctionnement humain. La prise en compte nouvelle des limitations d’activités permet de porter un regard renouvelé sur les priorités de santé publique et offre de nouveaux horizons pour chacune des branches de l’épidémiologie. L’intérêt de l’épidémiologie sociale pour les inégalités de santé et l’étude des liens complexes entre inégalités et handicap sert d’exemple pour évoquer les perspectives ouvertes par une socio-épidémiologie du handicap.

Monstre difforme, exposé et renié, objet de la vindicte des dieux ou des sanctions diaboliques, le corps humain physiquement différent n’a cessé d’interroger, de répugner ou de fasciner. Exhibé depuis la plus haute Antiquité, démantelé dès que la science a autorisé les pratiques de dissection anatomique, ce corps estropié, cet humain contrefait, qui, à mesure des avancées législatives et sociétales, deviendra une personne handicapée, sera, à son tour, objet d’études et d’interrogations, adossé aux progrès de l’archéologie et de sciences connexes. Si l’étude des pathologies s’est d’abord limitée à un inventaire clinique des cas mis au jour, des monstruosités ostéologiques retrouvées en contexte de fouilles, la paléopathologie, science récente et en constante évolution, ambitionne désormais d’étudier des humains, des situations, des comportements d’inclusion et d’exclusion, inscrivant le handicap au rang des composantes de sociétés passées, dont on tente d’appréhender les codes. Si elle ne doit pas écarter le volet médical, le diagnostic rétrospectif, la paléopathologie est une science qui s’intéresse à tous les humains, y compris à ceux en situation de handicap que leurs contemporains, au sein de tous les groupes et systèmes communautaires connus, ont soigné, appareillé, aidé ou rejeté, donnant ainsi accès à des schémas de pensée que ne peut proposer la seule approche textuelle.

L’étude détaillée des fonctions cognitives apporte des éléments utiles à la compréhension de la plupart des handicaps. Elle est particulièrement adaptée aux handicaps consécutifs à des difficultés cognitives, dont la déficience intellectuelle. Se situant dans la droite ligne du modèle biomédical, les premières recherches réalisées en psychologie cognitive étaient essentiellement centrées sur l’identification et la description de déficits dans les capacités de traitements de l’information. En opposition à cette vision statique de la déficience intellectuelle, les théories développementales se sont rapidement avérées incontournables pour expliquer les particularités associées à cette forme de handicap. Ces théories trouvent désormais leur prolongement dans les approches neuro-constructivistes et transactionnelles qui soulignent le rôle de l’activité de la personne et l’influence des interactions sociales sur la cinématique des trajectoires du développement cognitif des personnes affectées d’une déficience intellectuelle.

En quoi les savoirs sur le handicap peuvent-ils féconder l’éducation et la formation et, en même temps, orienter l’action politique ? Pour pallier les contradictions entre intention, discours et action, et accompagner les changements requis, quatre propositions sont formulées. La première, dans le champ de l’éducation, invite à concevoir une organisation des métiers d’éducation et un serment éthique, qui signifient clairement l’engagement de l’ensemble des membres du système éducatif à prendre en compte la question du handicap dans l’ordinaire de son exercice professionnel et à apporter une égale attention à tous les enfants, en situation de handicap ou non. La deuxième, dans le domaine de la formation, appelle à créer un groupe national Savoirs, Formation et Handicap , dont la mission serait de définir une matrice formative, composé d’un tronc commun interprofessionnel et d’arborescences par branches d’activités, professions et métiers. La troisième, sur le versant de la recherche, consiste en l’instauration d’un rendez-vous, à portée nationale et internationale, sous le nom d’ Entretiens scientifiques sur le handicap , sur le modèle de ceux de Bichat en médecine, pour faire un point régulier sur les grandes avancées des savoirs et assurer leur diffusion. Dans une visée politique, la quatrième est la création d’un Haut Conseil national de la politique du handicap, afin de garantir une action cohérente et pérenne.
Construire son autonomie sous contrainte
Authors: Cosson Arnaud
Published: December 2015

Les réformes contemporaines de l’action publique sont marquées par des mouvements ambivalents de « desserrement » et de « resserrement » du verrou de l’État. Nous étudions leurs conséquences dans la mise en œuvre de la réforme des parcs nationaux français de 2006. Nous focalisons l’analyse sur le travail concret et quotidien des directeurs chargés de l’appliquer. Le concept de cadre intermédiaire nous permet de caractériser leur rôle, de mettre en évidence les tensions auxquelles ils font face, leurs pratiques et la façon dont ils peuvent construire sous contrainte leur autonomie de réformateur.
Les îles anglo-normandes sous l’occupation allemande et la singularité des républicains espagnols en captivité (1 re partie : 1940-1943)
Authors: Pike David Wingeate , Farache Anne
Published: December 2015

L’exode des Républicains espagnols, à partir de l’Espagne puis de la France, recouvre des expériences bien diverses. Certains s’exilèrent en URSS, d’autres en Amérique latine mais 10 000 hommes de ceux qui choisirent de rester en France tombèrent dans les mains des Nazis en 1940. Nombre d’entre eux furent déportés en Allemagne et certains furent incorporés pour construire le mur de l’Atlantique, notamment dans les îles anglo-normandes. Parmi ces îles, Aurigny fut la plus singulière car Churchill avait fait évacuer la population avant l’invasion allemande. L’île désertée devint le seul endroit du territoire britannique sur lequel il y eut des camps SS. Les Espagnols déportés à Aurigny partagèrent les souffrances des Juifs et autres ennemis du Reich en captivité sur cette île.

L’embarras face aux mouvements psychotiques en institutions éducatives
Authors: Marchand Frédérique
Published: December 2015

Aux heures sombres où notre société polémique sur la question : « Pouvons-nous rire de tout ? », la sphère médicosociale s’embarrasse des questions diagnostiques de psychose, bute quant à la prise en compte des sujets à risque psychotique ou dont la dangerosité ressentie ou supposée interroge les limites de la prise en charge éducative des adolescents. Ce malaise nosographique se dit de manière défensive par le recours à l’humour entre collègues ; un humour qui relativise, un humour qui dédramatise. Max Jacob disait de l’humour qu’il ne blessait pas et qu’il amusait. Nous interrogeons ici l’impact d’un diagnostic non établi mais subjectivé à partir de manifestations comportementales objectives ou tout du moins observées sur la construction du sujet. Le diagnostic de psychose peut-il blesser ? Est-il nécessaire à la prise en charge éducative des adolescents ?
Inventer des possibles dans le travail éducatif

Face à des troubles relevant de phénomènes psychotiques, les inter-venants sociaux et éducatifs sont souvent mis à mal et dépourvus, souhaitant « passer la main » et remettant en question leurs compétences. Pourtant, leurs inter-ventions ont du sens à partir du moment où elles restent soutenues par un travail d’équipe et étayées par les dispositifs de soins existants. La collaboration entre les différents inter-venants se doit d’être encouragée afin d’envisager des possibles dans le travail éducatif et d’adapter les réponses dans des situations particulièrement anxiogènes.
Aux frontières de l’autisme et de la psychose infantile. La place d’importance de la psychanalyse dans le champ de la psychiatrie de l’enfant
Authors: Mesquita Mirka
Published: December 2015

L’autisme et la psychose infantile peuvent présenter un seuil symptomatologique très étroit, pour certains cas. Il s’avère que des équivoques sont fréquentes dans le diagnostic des enfants dont l’ensemble de symptômes n’est pas précis. La présente étude analyse les éléments qui provoquent cette confusion symptomatologique et propose une clinique différentielle entre ces deux entités nosologiques. L’écoute épurée du discours du patient reste l’élément essentiel à la pratique diagnostique et à toute prise en charge de la souffrance psychique chez l’enfant. Cette étude porte sur la reconnaissance de l’importance de l’approche psychodynamique, notamment la psychanalyse, pour le champ pédopsychiatrique.
Drogues et précarité sociale : un risque pour la relation mère-bébé

Published: December 2015

Le présent travail a pour objectif une réflexion sur les interventions réalisées au sein du réseau de protection de l’enfance, incluant la dimension judiciaire, auprès des femmes enceintes considérées comme addictives et en situation de désespoir social dans la ville de Rio de Janeiro. Ces dernières années, il y a eu un accroissement significatif du nombre de femmes usant du crack, y compris parmi les adolescentes, dans cette ville. En tant que psychologues travaillant pour le tribunal de l’enfance et de la jeunesse, nous observons une hausse du nombre de cas de bébés, amenés par le biais des maternités dans le service judiciaire, afin que le juge décide si l’enfant reste avec la mère ou en est séparé provisoirement, car considéré en situation de risque. L’inter-vention du judiciaire, qui devrait être celle du dernier recours, prend la première place et se substitue aux politiques de santé et d’assistance sociale. Il devient fondamental, alors, de repenser cette -logique, en problématisant les effets de telles inter-ventions dans la vie de ces mamans et de leurs bébés.
L’innocence
Authors: Chabert Catherine
Published: December 2015

Trois motifs sont traités à partir du rapport et de la conférence de Christian Seulin : l’innocence, la dynamique pulsionnelle et la douleur. L’innocence renvoie à la passivité requise dans la forme classique des fantasmes de séduction, contre-investie et retournée en son contraire dans leur forme « mélancolique ». Les mouvements mobilisés dans la construction de l’objet et du moi inscrivent la dynamique pulsionnelle dans son double versant, en termes de pulsions libidinales et pulsions de mort, au sein même de la sexualité infantile, dès ses commencements. Enfin, au-delà de la perte et de ses effets, la douleur constitue une expérience radicale, indispensable, aux origines du sexuel infantile.
Deux questions sur le sexuel infantile
Authors: Diatkine Gilbert
Published: December 2015

Le sexuel infantile est responsable de l’irruption dans la cure des idées incidentes qui surviennent dans l’esprit de l’analyste et lui donnent à voir, comme sur une scène de théâtre, les scénarios inconscients de son patient. Ces manifestations passent par le langage, mais aussi par des images qui viennent à l’esprit de l’analyste, et par des gestes que fait ou que décrit le patient. Le sexuel infantile s’oppose à la sexualité infantile, qui est faite des évènements de la vie sexuelle de son enfance dont parle le patient. L’investissement du corps de l’enfant par ses parents joue un rôle important mais limité dans la construction du sexuel infantile.
La plume de ma mère

Published: December 2015

La dramatisation, fugitivement identifiée par Freud dans le travail du rêve, désigne la transformation par laquelle, dans des conditions diverses, l’activité psychique se rapproche de son statut animique premier, qui est d’accomplissement du désir. On en retrouve les traits essentiels dans certaines formes d’actualisation transférentielle, où la situation créée par la mise en action trouve dans l’accueil de la situation analytique les conditions transitionnelles d’une mise en représentation scénarisée. Ce serait la force projective de l’illusion qui fonde l’intensité de l’effet d’après-coup, et la valeur irremplaçable de l’interprétation passant par l’agieren.

AUTOMATIC AND CONCURRENT DETERMINATION OF OPTIMAL VALUES OF NONLOCAL MEANS FILTERING PARAMETERS BASED ON BAYESIAN FORMULATION IN IVUS IMAGES
Authors: Golchin Elnaz , Setarehdan Seyed Kamaledin , Behnam Hamid
Published: December 2015

A challenging issue that has emerged regarding nonlocal means filtering based on Bayesian formulation in order to remove noises from ultrasound images is the determination of the optimal parameters of this filtration without the involvement of users concurrently before the start of the filtration. This issue is effective in both the filtration quality and the time required for process. This paper, presents an algorithm based on optimization algorithm in order for automatic and concurrent determination of the optimized parameters of this filter. The intravascular ultrasound (IVUS) images used for experiments and evaluation of the results have been taken from seven different individuals. The resolution of these images is [Formula: see text] pixels that is prepared by a transducer at a frequency of 30[Formula: see text]Mhz at 0.55[Formula: see text]m/s. The proposed algorithm works by combining nonlocal means filtering based on Bayesian formulation with genetic optimization algorithm. The cost function of the genetic algorithm is introduced based on the intended filter. In order to evaluate the algorithm proposed in this paper, a two-stage evaluation process was. At the first stage examinations, 50 IVUS images were recorded in 50 experiments of the applied proposed algorithm. The values of evaluation criteria and output images were then recorded and organized in a descending order. Ten preliminary groups of these parameters that had the best results in terms of the intended criteria were chosen for the second stage experiments. The second stage includes 30 experiments on 30 images not seen so far by the proposed algorithm. The details of the results are provided within the paper text extensively together with the obtained tables. In this paper, we have tried to simplify the way nonlocal means filtering should be used to improve the quality of intravascular ultrasound (IVUS) images. To this end, the algorithm proposed in this research calculates the optimal values of the parameters of this filter before filtration automatically with no user involvement. It also carries out the filtration using the optimal values of parameters that are the outputs of the proposed algorithm thereby increasing the quality of filtration by optimized parameters.

Patient’s emotional reactions in cardiac rehabilitation: analysis and perspectives
Authors: Balestroni Gianluigi , Giannuzzi Pantaleo
Published: December 2015

Subject: Evaluation and treatment of psychological diseases are often included in cardiology rehabilitation programs. The aim of this study was to analyze the emotional reactions in a very consistent sample of cardiac patients, hospitalized for a rehabilitation program. Materials and methods: The sample consisted of 5417 patients, 4563 males and 854 females, with a mean age of 57.36±9.15 (range 18-83). They were admitted in the period between 1995 and 2005 and completed the Cognitive Behavioral Assessment, Hospital form (CBA-H) Results: Significant level of state- anxiety was shown by 27.8% of the subjects, 22.1% reported health-related fears and 10% depressive symptoms. Women show higher scores in all of the three scales, and patients over 65 years scored higher in the depression scale. It is interesting to note that the mean scores in the three scales showed a progressive and significant decrease over the years. Conclusions: These data confirm that an accurate psychological screening can be extremely useful to support the Psychologist working in cardiac rehabilitation as it helps to plan more specifically the interventions, focusing on the objective patients’ educational and psychological needs.
Habitat suitability models and carrying capacity estimations for rock ptarmigans in a protected area of the Italian Alps
Authors: Nelli Luca
Published: December 2015

Rock ptarmigan populations in the Alps are suffering an overall decline, and management actions are needed to ensure their conservation. Yet wildlife management and conservation actions are often the consequences of political decisions taken by subjects that lack the scientific knowledge about the relationships between the environment and species ecology. Habitat suitability models are tools that translate these complex relationships into mathematical models and spatially explicit maps of potential presence and abundance of species that are easier to understand by people not experienced with the study of biological processes. In this study, I modelled the species-habitat relationships at two levels, by estimating the potential distribution and potential density of the species in a protected area of the Western Italian Alps. In particular, I took the results of a previous study carried out in the same area to estimate the probability of male occurrence by comparing the habitat structure in presence plots and random plots, respectively, by logistic regression analyses. Then, I applied the logistic regression equation to the same variables measured in hexagonal cells of a grid superimposed over the entire study area, and I obtained the map of the potential distribution of the species. Finally, I developed multiple regression analyses of male density estimated by distance sampling vs habitat variables, and I applied the results to the areas of potential distribution to forecast the potential density and therefore the carrying capacity of the study area. I obtained a potential distribution of 38.2 km2, with a potential average density of 5.1 males/km2. The latter was positively affected by the percentage cover of grassland and rocky grassland in the plots. The integrated approach that I used by combining models of occurrence and density allowed me to confirm and improve the results of previous works on rock ptarmigan predicted occurrence, to identify areas of conservation importance within the protected area and to give useful tools for spatially explicit management to the Natural Park administrators.

Published: December 2015

The main aim of this paper is to empirically assess defense mechanisms trends and personality structure in a once a week psychoanalytically oriented psychotherapy with an early adolescent, affected by a General Anxiety Disorder (GAD). Assessment and outcome measure included the Shedler-Westen Assessment Procedure for Adolescents (SWAP-200-A); process was evaluated through defensive mechanisms analysis, using Defense Mechanisms Rating Scale (DMRS). The paper focused on 12 sessions divided into three periods, along 2 years of treatment. Quantitative and narrative profiles of SWAP-200-A and DMRS were integrated; a log linear procedure was chosen to assess defensive mechanisms trends longitudinally during the treatment. Moreover a Multiple Correspondence Analysis (MCA) was applied to DMRS to provide a map of the evolution of the patterns of defense mechanisms throughout the course of treatment. Personality assessment and defensive mechanisms showed an inhibited self-critical image with obsessive, narcissistic and disavowal patterns. According to trends during treatment phases, MCA analysis identified decreasing in defensive patterns, while mature defenses increased significantly. The study highlighted how non-intensive psychoanalytic psychotherapy can help early adolescents with clinical problems to improve their overall mental functioning. Outcome in terms of personality structural changes and process according to defense mechanisms were discussed to highlight improvement not just in symptomatology, but also in personality structure and functioning.

Authors: Munhoz Driemeier Schmidt Fernanda , Pacheco Fiorini Guilherme , Rohnelt Ramires Vera Regina
Published: December 2015

Researchers and clinicians seem to agree that the psychotherapistâ€™s pregnancy is an unique moment of psychotherapy psychoanalytic process. In Brazil, 89% of psychologists belong to the female gender, being that the practice of psychotherapy, in its great majority, is performed by women. In spite of the relevance of the subject and of its impact on psychotherapies, there are few current studies, most of them dealing with adult patients. The objective of this study was to perform a systematic review of the literature about pregnancy of the psychotherapist in psychoanalytic psychotherapy. All the articles found in the search of indexed scientific publications, which can be accessed on-line, with an approach about the pregnant psychotherapist in psychoanalytic psychotherapy, were included and discussed in this revision. Besides this, the methods, the results and the repercussions of the treatment, were analyzed. It is revealed that there is a lack of studies in this area, because most of the found articles were dated twelve years ago or more. The studies are of a qualitative exploratory methodology, with small samples, from retrospective data collection from the period when the therapists were pregnant. Pregnancy is discussed as a strong catalyzer for the transference and/or for countertransferential reactions. No items of research were found on the subject from the patient or his familyâ€™s perspective, as well as studies about the psychoanalytic psychotherapy process. It is concluded that other studies on this issue are necessary for the better understanding of this psychotherapeutic moment.

It is important to investigate the outcomes of psychotherapy and, especially, its process. Regarding child psychodynamic psychotherapy, available studies are in smaller numbers. Therefore, we still do not fully know the mechanisms of change in treatments with this age group. The Child Psychotherapy Q-Set (CPQ) was designed to analyze the therapeutic process with children. It permits one to identify interaction structures (i.e., repetitive patterns of interaction) and how they change in the course of a treatment. Based on these assumptions, the aim of this study was to identify and to analyze the interaction structures in the psychodynamic therapy of a boy diagnosed with Aspergerâ€™s disorder and possible changes in his psychic organization. A mixed longitudinal study, based on the Systematic Case Study procedure, was performed. Approximately 30 months of the boyâ€™s psychotherapy were analyzed using the CPQ. The Rorschach method was used as the outcome measure. Four interaction structures were identified, using the CPQ: Active, confident and lively child, competing with connected, mentalizing and accepting therapist; Withdrawn and defensive child with uncertain, unresponsive and didactic therapist; Accepting therapist with demanding, provocative and hostile child; and Reassuring, supportive, nondirective therapist with a compliant and not spontaneous child. Two interaction structures varied over time. Some changes in Rorschach variables were detected after two years of treatment.
Audiology practice management in South Africa: What audiologists know and what they should know
Authors: Breytenbach Deidré , Kritzinger Alta , Soer Maggi
Published: December 2015

Background: In future, the South African Department of Health aims to purchase services from accredited private service providers. Successful private audiology practices can assist to address issues of access, equity and quality of health services. It is not sufficient to be an excellent clinician, since audiology practices are businesses that must also be managed effectively.Objective: The objective was to determine the existing and required levels of practice management knowledge as perceived by South African audiologists. Method: An electronic descriptive survey was used to investigate audiology practice management amongst South African audiologists. A total of 147 respondents completed the survey. Results were analysed by calculating descriptive statistics. The Z-proportional test was used to identify significant differences between existing and required levels of practice management knowledge. Results: Significant differences were found between existing and required levels of knowledge regarding all eight practice management tasks, particularly legal and ethical issues and marketing and accounting. There were small differences in the knowledge required for practice management tasks amongst respondents working in public and private settings. Conclusion: Irrespective of their work context, respondents showed that they need significant expansion of practice management knowledge in order to be successful, to compete effectively and to make sense of a complex marketplace.

The aim of the paper was to compare the effect of prebiotics (inulin and/or mannan-oligosaccharides, MOS) and bee products (bee pollen and/or propolis) on productive and reproductive performance of rabbit does. Seventy nulliparous V-line female rabbits were distributed among 7 groups. The groups were fed the same diet and received no supplements (control group), natural molecules (bee pollen and/or propolis) at 200 mg/kg body weight (BW) or prebiotics (inulin and/or MOS) at 35 mg/kg BW. Productive, reproductive, biochemical and haematological traits were investigated. Bee pollen with propolis significantly increased body weight gain of does 1 wk after mating (3.53%), decreased feed intake (4.49%) and caused larger litter size (39.4%), heavier body weight of litter (17.7%), a greater number of kits born alive (48.7%), higher weight of kits (87.81%) at 28 d of age, higher milk yield (43.6%) and more favourable milk conversion ratio (31.6%). Moreover, bee pollen with propolis had significantly increased plasma total protein (43.1%), albumin (45.7%), globulin (41.0) and progesterone (60.5%), and had a significantly decreased plasma cholesterol (31.1%), aspartate aminotransferase/alanine aminotransferase ratio (20.3%) compared to the control group. Does treated with growth promoters had significantly fewer services per conception (22%) and greater fertility rate (21%) compared to the control group. Inulin with or without MOS significantly increased plasma glucose (49.9 and 50%, respectively) and feed cost (90.2%) compared to the control group. Supplementation of MOS or bee pollen with or without propolis had significantly greater relative economic efficiency (61.9, 55.1 and 27.1%, respectively) than the control group. MOS and bee pollen with or without propolis are able to improve productive and reproductive performance and economic efficiency of rabbit does in comparison to the unsupplemented group.
Use of inter simple sequence repeats and protein markers in assessing genetic diversity and relationships among four rabbit genotypes
Authors: El-Sabrout K. , Aggag S.A.
Published: December 2015

The importance of DNA and protein applications as powerful tools in breeding programmes is revealed. The inter simple sequence repeats (ISSR) technique was used to characterise and determine phylogenetic relationships among 4 genotypes of rabbit, namely Alexandria (Alex), V line (V), New Zealand White (NZW) and California (Cal). Six out of 7 ISSR primers exhibited sufficient variability and were used to characterise the genetic diversity and relationships among studied genotypes. A total of 141 DNA  ands were detected. DNA fragments were generated with 87 (61.7%) being polymorphic, indicating considerable genetic variation among the examined genotypes. While protein electrophoresis provides a precise method for assaying variation in serum proteins which play an important part in productive performance. The results demonstrated 2 specific protein markers in Alexandria rabbits; these specific protein markers may be responsible for the superiority of Alexandria line in weight. Phylogenetic analysis based on Nei and Li unbiased genetic distance illustrated that (Alex & V) and (Cal & V) were genetically closely related. Our results showed that ISSR and protein electrophoresis are useful methods to detect different genetic expressions and understand the variability in some productive traits in rabbits.

Olive cake is one of the main agro-industrial co-products in the Mediterranean area of Spain, with high availability almost all year round. In addition, most of the product is dehydrated, which increases its interest in monogastric species such as rabbits. Nineteen samples from various Spanish oil mills using different processing methods were analysed for their chemical composition and in vitro digestibility. The average composition was [in dry matter (DM) basis]: ash (9.64%), neutral detergent fibre (52.0%), acid detergent fibre (36.8%), acid detergent lignin (19.1%), crude protein (CP) (11.3%), insoluble neutral (8.0%) and acid detergent crude protein (5.15%), ether extract (10.9%) and gross energy (21.9 MJ/kg). DM and CP in vitro digestibility were, on av., 53.4 and 41.4% respectively. High variability was observed among the samples for most of the traits studied. Fibrous fractions were highly correlated among them and negatively with ether extract content, whereas CP was little related to other feed components. A stepwise regression analysis allowed us to determine regression equations to predict DM and CP in vitro digestibilities from chemical composition (R2=0.80 and 0.91, respectively). As regards the current results, olive cake has potential use for rabbits as a source of insoluble fibre and lignin. Crude samples (not oil extracted) combined with sieving to retain the smaller particles have an additional interest, because of their higher energy value and significant supply of high quality fat.
