Environmental Impact of Some Retrofit Options Applied to an Inland Vessel
Authors: Hargitai Csaba , Schweighofer Juha , Simongáti Győző
Published: June 2017

The project MoVe IT! (www.moveit-fp7.eu), funded by the Seventh Framework Programme of the European Union, aims at a modernisation of inland waterway vessels with focus on retrofitting of existing vessels and technology transfer from new buildings and other transport modes. The topics of the project refer to the improvement of energy efficiency and environmental behaviour of inland waterway vessels, as well as the implementation of alternative energy sources to gasoil. Environmental assessment of various retrofit options is one major objective of the MoVe IT! project. The analysis is carried out for five vessels, comprising a container vessel, three pushers and a motor cargo vessel being operated together with a lighter. In this paper only the analysis of this last vessel is presented. The effects of the different retrofit solutions to be applied in this vessel are taken into account by the resulting reduction of the fuel consumption or directly the respective emissions in per cent. To obtain a wider picture, the emissions referred to tkm are compared with the ones of road transport carried out with trucks complying with emissions standards EURO III up to Euro VI, as well as the East European emission standard (EE).
Symmetrical brachydactyly in a dog
Authors: Krotscheck Ursula , Fischetti Anthony , Tong Kim , Cray Megan
Published: June 2017

Congenital malformations of the canine manus and pes are infrequently reported in the veterinary literature. This includes brachydactyly which is a general term used to indicate the shortening of digits due to abnormal development of the phalanges, metacarpals, or metatarsals. This case report describes isolated brachydactyly in a one-year-old male Maremma Sheepdog affecting all of the phalanges, metacarpals, and metatarsals of digits two through five. This condition was confirmed by determining the length of each phalanx, metacarpal, and metatarsal of the affected dog as well as an unaffected littermate. The affected dog’s metacarpal, metatarsal, and phalanx lengths ranged from 50% to 77% of that of the unaffected sibling. Other abnormalities found on physical examination as well as on radiographic imaging are discussed.
Nectar sampling for prairie and oak savanna butterfly restoration
Authors: Arnold Paige M. , Michaels Helen J.
Published: June 2017

Premise of the study:

Understanding floral resources is vital for restoring pollinators in habitats affected by anthropogenic development and climate change. As the primary adult food, nectar can limit butterfly longevity and reproduction. For pollinator restoration, it would therefore be useful to examine nectar resources. However, because many flowers preferred by butterflies are too small for microcapillary sampling and the potential for nectar contamination can make accurate measurement difficult, we developed a modified centrifugation method to extract and separate nectar and pollen.

Methods:

We sampled nectar from 19 forbs using a glass wool filter to exclude potentially contaminating pollen during centrifugation. To minimize costs, we measured sugar concentration by refractometry and simple ninhydrin tests for amino acids and improved test accuracy by subsequent image analysis. Artificial nectars were used to verify the new techniques.

Results:

This method eliminated pollen from samples, while only slightly increasing sugar concentrations. Some amino acids were lost during centrifugation, but only samples with high concentrations exhibited substantial loss. We found significant differences in nectar quality among species, as well as an unexpected inverse relationship between amino acid and sugar concentrations.

Discussion:

This modified centrifugation technique is an efficient, less damaging, inexpensive approach for collecting nectar from small flowers while eliminating pollen contamination, and will facilitate restoration of declining pollinators and thereby the plants they service.
Bright fluorescent silica-nanoparticle probes for high-resolution STED and confocal microscopy

Published: June 2017

In recent years, fluorescent nanomaterials have gained high relevance in biological applications as probes for various fluorescence-based spectroscopy and imaging techniques. Among these materials, dye-doped silica nanoparticles have demonstrated a high potential to overcome the limitations presented by conventional organic dyes such as high photobleaching, low stability and limited fluorescence intensity. In the present work we describe an effective approach for the preparation of fluorescent silica nanoparticles in the size range between 15 and 80 nm based on L-arginine-controlled hydrolysis of tetraethoxysilane in a biphasic cyclohexane–water system. Commercially available far-red fluorescent dyes (Atto647N, Abberior STAR 635, Dy-647, Dy-648 and Dy-649) were embedded covalently into the particle matrix, which was achieved by aminosilane coupling. The physical particle attributes (particle size, dispersion, degree of agglomeration and stability) and the fluorescence properties of the obtained particles were compared to particles from commonly known synthesis methods. As a result, the spectroscopic characteristics of the presented monodisperse dye-doped silica nanoparticles were similar to those of the free uncoupled dyes, but indicate a much higher photostability and brightness. As revealed by dynamic light scattering and ζ-potential measurements, all particle suspensions were stable in water and cell culture medium. In addition, uptake studies on A549 cells were performed, using confocal and stimulated emission depletion (STED) microscopy. Our approach allows for a step-by-step formation of dye-doped silica nanoparticles in the form of dye-incorporated spheres, which can be used as versatile fluorescent probes in confocal and STED imaging.

Objective:  to identify the stress levels and sleeping habits of students from the Physical Education college during the diurnal and nocturnal periods.

Method: this is an exploratory and descriptive study with 103 subjects. Data were collected through the Lipp Stress Symptom Inventory and the Horne & Östberg Morningness-Eveningness Identification Questionnaire, and sociodemographic data.

Results: The stress indexes showed 53.40% of students without stress and 46.6% with stress. When comparing gender and stress using the chi-square test, one obtained (p=0.0411), indicating that women are more stressed than men. There were 61.1% of students classified with indifferent chronotype. Among the students, 80.4% from the diurnal period were not suitable for the chronotype, as well as 74.5% of the students from the nocturnal period were not either.

Conclusion: the majority of the students did not present the chronotype adequate for the study schedule and they presented stress, being more frequent in the female group.

L’élaboration des politiques sur l’intégration des immigrants en Italie. Les politiques régionales du point de vue de la gouvernance à niveaux multiples
Authors: Campomori Francesca , Caponio Tiziana
Published: June 2017

Le présent article contribue au débat sur le « virage vers la gouvernance locale » en examinant un contexte d’immigration récente tel que l’Italie. Nous analysons les politiques d’intégration et les processus de gouvernance dans trois régions : la Lombardie, le Piémont et l’Émilie-Romagne. Notre but est de mieux comprendre les relations de gouvernance à niveaux multiples (GNM) qui déterminent les politiques d’intégration des immigrants en prenant en considération les interdépendances des dimensions verticale et horizontale de la GNM. L’analyse met en lumière l’émergence de différents modes de GNM et souligne l’importance des facteurs institutionnels et organisationnels dans la différenciation locale. Il apparaît que les traditions générales et les relations établies entre le secteur public et les ONG dans le domaine des politiques sociales, l’organisation interne de l’administration régionale (avec le personnel spécialisé par opposition à l’appareil bureaucratique général) et le rôle de l’idéologie ont une influence sur le cours des choses. Nous analysons les implications de cette analyse pour les recherches sur la GNM et insistons sur la nécessité d’adopter une approche théorique de niveau moyen. Remarques à l’intention des praticiens Les chercheurs en politique considèrent la GNM comme une approche prometteuse pour comprendre les processus d’élaboration des politiques de plus en plus complexes, qui supposent des interactions entre différents niveaux de gouvernement et entre des acteurs publics et non publics. Dans le présent article, nous nous intéressons à la question délicate au niveau politique de l’intégration des immigrants pour mettre en lumière la manière dont les relations de GNM prennent forme concrètement au niveau régional en Italie, des relations dans lesquelles certains facteurs expliquent la différenciation régionale. Notre étude indique que les facteurs contextuels et organisationnels sont particulièrement pertinents, à savoir les traditions en matière de politique sociale, l’organisation interne des régions et les attitudes des différents agents de l’État. Il n’en reste pas moins que les aspects politiques doivent eux aussi être pris en considération.
Visages du Brésil méridional : l´immigration polonaise et italienne au Paraná entre la fin du XIXe et le début du XXe siècle
Authors: Oliveira Márcio de
Published: June 2017

L´immigration au Brésil est toujours étudiée de façon générale et nationale. Des données statistiques nous montrent qu´elle a été surtout méridionale, c´est-à-dire, vers les états de São Paulo, du Paraná, de Santa Catarina et de Rio Grande do Sul. Cette étude analyse l´immigration polonaise et l´immigration italienne au Paraná. Les organisations polonaises ont été nombreuses et diverses, depuis les écoles, en passant par les associations sportives, juqu´aux journaux, ce qui contredit l’idée courante des Polonais illetrés. La communauté y était si importante qu´on a même songé à créer, dans l´état du Paraná, une colonie de la République polonaise. Les Italiens n´ont pas été si nombreux mais ils ont été très actifs. Aussi bien dans la ville de Curitiba, la capitale de l´état, que dans les alentours, ils ont demontré une très grande vitalité dans l´organisation des associations culturelles et il est possible d´en reconnaître les conséquences de nos jours.

O artigo propõe a reflexão sobre os processos comunicacionais da atividade laboral em discursos institucionais. Visa a investigar a cenografia que implica o ethos da atividade laboral, mediante a enunciação de trabalhadores na discursivização do processo comunicacional instituído pela exposição virtual ‘Vida de embarcado’, do programa ‘Memória Petrobras’. Para tanto, articula noções de cultura (Morgan, 2011), comunicação (Marchiori, 2013) e trabalho (Schwartz & Durrive, 2007) por meio da análise dialógica (Bakhtin, 2015) e do ethos (Maingueneau, 2013, 2008, a, b). Trata-se de um estudo de natureza aplicada e abordagem qualitativa ao objeto empírico. Como principal resultado, ressalta-se que a discursivização do processo comunicacional por meio da enunciação dos trabalhadores da Petrobrás produz um ethos discursivo da atividade laboral centrado na tarefa, nas prescrições e no uso de si pelo outro.
Managing Nigeria’s development through the public budget: Lessons from the foundations laid by Okotie-Eboh, 1958–1965
Authors: Ogunyemi Adetunji
Published: June 2017

This article examines the essential issues in the economic development of Nigeria in the 1960s as shown in all the budget speeches presented to the parliament by her first indigenous Finance Minister, Festus Okotie-Eboh. The study highlights the Minister’s efforts to obtain parliamentary approval for the Appropriation Bills laid by his government before the Nigerian House of Representatives in Lagos. The purpose being to underscore the role of the individual in shaping the course of the development of any nation. Hence, the study identifies the fiscal policy orientation upon which the key programmes and projects reflected in such speeches were built. It also establishes the extent to which the projects were achieved. The study concludes that Chief Okotie-Eboh’s parliamentary speeches on Nigeria’s federal budget, though loaded with oversized literary niceties, were still, rather than depictive of a mere display of endless parliamentary filibustering, indeed, a veritable part of the sources of Nigeria’s public history.
Epidemiology of Musculoskeletal Tuberculosis in an Area with High Disease Prevalence
Authors: Held Michael F. G. , Hoppe Sven , Laubscher Maritz , Mears Stewart , Dix-Peek Stewart , Zar Heather J. , Dunn Robert N.
Published: June 2017

Study Design

Retrospective observational study.

Purpose

The aim of this study was to assess the distribution of age and site of infection in patients with musculoskeletal tuberculosis (TB) and determine the number of TB/human immunodeficiency virus (HIV) coinfections as well as the incidence of multidrugresistant (MDR) TB.

Overview of Literature

Of all TB cases, 1%–3% show skeletal system involvement and 30% are HIV coinfected. Although the reported distribution of skeletal TB is majorly in the spine, followed by the hip, knee, and foot/ankle, the epidemiology of extrapulmonary TB and especially musculoskeletal TB remains largely unknown, particularly in areas with a high prevalence of the disease.

Methods

This is a retrospective study of a consecutive series of patients admitted to a tertiary care facility in an area with the highest prevalence of TB worldwide. TB was confirmed on tissue biopsy with polymerase chain reaction testing (Xpert for Mycobacterium tuberculosis and rifampicin resistance), culturing, or histological analysis. Data were analyzed regarding demographic information, location of the disease, HIV coinfections, and drug resistance.

Results

In all, 125 patients (44 children; 35%) with a mean age of 27 years (range, 1–78 years) were included. Age peaks were observed at 5, 25, and 65 years. Spinal disease was evident in 98 patients (78%). There were 66 HIV-negative (53%) and 29 (23%) HIVpositive patients, and in 30 (24%), the HIV status was unknown. Five patients (4%) showed MDR TB.

Conclusions

The age distribution was trimodal, spinal disease was predominant, MDR TB rate in our cohort was high, and a large portion of TB patients in our hospital were HIV coinfected. Hence, spinal services with sufficient access to operating facilities are required for tertiary care facilities in areas with a high TB prevalence.
Polymicrobial and Monomicrobial Infections after Spinal Surgery: A Retrospective Study to Determine which Infection is more Severe
Authors: Liu Shaoqiang , Qi Qiang , Chen Zhongqiang , Liu Ning , Guo Zhaoqing , Sun Chuiguo , Li Weishi , Zeng Yan , Liu Zhongjun
Published: June 2017

Study Design

A retrospective clinical review.

Purpose

To investigate the difference in clinical manifestations and severity between polymicrobial and monomicrobial infections after spinal surgery.

Overview of Literature

Surgical site infections (SSIs) after spinal surgery are a major diagnostic and therapeutic challenge for spinal surgeons. Polymicrobial infections after spinal surgery seem to result in poorer outcomes than monomicrobial infections because of complementary resistance to antibiotics. However, comparison of the clinical manifestations and severity between polymicrobial and monomicrobial infections are limited.

Methods

Sixty-seven patients with SSIs after spinal surgery were studied: 20 patients with polymicrobial infections and 47 with monomicrobial infections. Pathogenic bacteria identified were counted and classified. Age, sex, and body mass index were compared between the two groups to identify homogeneity. The groups were compared for clinical manifestations by surgical site, postoperative time to infection, infection site, incisional drainage, incisional swelling, incisional pain, neurological signs, temperature, white blood cell count, and the percentage of neutrophils. Finally, the groups were compared for severity by hospital stay, number of rehospitalizations, number of debridements, duration of antibiotics administration, number of antibiotics administered, and implant removal.

Results

Polymicrobial infections comprised 29.9% of SSIs after spinal surgery, and most polymicrobial infections (70.0%) were caused by two species of bacteria only. There was no difference between the groups in terms of clinical manifestations and severity. In total, 96 bacterial strains were isolated from the spinal wounds: 60 strains were gram-positive and 36 were gram-negative pathogenic bacteria. Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, and Enterobacter cloacae were cultured in order of the frequency of appearance.

Conclusions

Most polymicrobial infections were caused by two bacterial species after spinal surgery. There was no difference in clinical manifestations or severity between polymicrobial and monomicrobial infections.
Severe Rigid Scoliosis: Review of Management Strategies and Role of Spinal Osteotomies
Authors: Kandwal Pankaj , Vijayaraghavan Govindaraja Perumal , Nagaraja Upendra Bidre , Jayaswal Arvind
Published: June 2017

Severe rigid curves pose a considerable challenge to the treating spine surgeon. In our practice, approximately 30%–40% of patients with scoliosis present late with severe rigid scoliosis (>90° and <30% correction on bending films). Controversy still exists with regard to the ideal surgical strategy for correcting these rigid curves. Rigid scoliosis often presents in the form of either sharp angular or rounded deformities. Rounded deformities can be effectively managed with an anterior release to loosen the apex and posterior instrumentation (with osteotomies, if required). In contrast, severe rigid scoliosis, which is a sharp angular deformity, is not very amenable to anterior release and is best managed by posterior-only vertebral column resection and posterior instrumentation.
Variations on Hermite Methods for Wave Propagation
Authors: Vargas Arturo , Chan Jesse , Hagstrom Thomas , Warburton Timothy
Published: June 2017

Hermite methods, as introduced by Goodrich et al. in [15], combine Hermite interpolation and staggered (dual) grids to produce stable high order accurate schemes for the solution of hyperbolic PDEs. We introduce three variations of this Hermite method which do not involve time evolution on dual grids. Computational evidence is presented regarding stability, high order convergence, and dispersion/dissipation properties for each new method. Hermite methods may also be coupled to discontinuous Galerkin (DG) methods for additional geometric flexibility [4]. An example illustrates the simplification of this coupling for Hermite methods.
Work Integrated Learning and the Case for a “Student-Industry Network” in Undergraduate Construction Management Programs
Authors: Forsythe Perry
Published: June 2017

The term “work ready graduates” is commonly used by Universities to describe students who have been well prepared and who can seamlessly enter professional practice. It is an ideal that is simpler said than achieved in reality. Students in construction management often work and study concurrently but this is often undertaken in an ad hoc way that does not derive the benefits of the potential synergy between the two. The paper explores the need to create such synergy by operationalising Work Integrated Learning concepts and the issues and conditions involved in implementing at the study-work interface for construction management students. The extant literature is used to build the case and identify relevant issues that need to be addressed in the context of contemporary higher education thinking. Research findings are presented from the perspective of the university sector, the student and the industry. Based on findings and insights from these stakeholders, the paper proposes a means of enabling Work Integrated Learning via a structured student-industry network. The brief for such a network is introduced with a view to real world application.

Establishment of Performance Scales for Team Integration Assessment
Authors: Ibrahim Khairil Izam , Costello Seosamh B , Wilkinson Suzanne
Published: June 2017

The increased use of the alliance model in recent years highlights the importance of integration practice among multi-disciplinary teams, as it promotes a collaborative culture and the continuity of equitable relationships to improve project performance. If continuous improvement in project alliances is to be achieved through the use of integrated teams, then a means of assessing how well teams integrate and how team integration changes over time, needs to be introduced. In response to that need, an Alliance Team Integration Performance Index (ATIPI) has been developed as part of a wider study to develop an assessment tool for team integration in road construction alliance projects in New Zealand. In this paper, a set of Key Indicators (KIs) of team integration practice and the Quantitative Measures (QMs) for each KI are first introduced and then, in order to enhance the associated ATIPI model, the establishment of scales for the performance levels, namely ‘poor’, ‘average’, ‘good’, ‘very good’ and ‘excellent’, for each KI are described. The establishment of performance scales will help ensure that the assessment of team integration practice is quantified in a consistent and objective manner. Keywords: Alliance, Assessment, New Zealand, Performance Scales, Team Integration
Association of VLDLR haplotypes with abdominal fat trait in ducks

Published: June 2017

Abstract. This study aimed to determine the correlation among VLDLR (very low-density lipoprotein receptor) gene polymorphisms, body weight and abdominal fat deposition of Gaoyou ducks. A total of 267 Gaoyou ducks from one pure line was employed for testing. The polymorphisms of the VLDLR gene were screened by polymerase chain reaction and DNA sequencing. Four novel single nucleotide polymorphisms (SNPs) (g.151G  >  A, g.170C  >  T, g.206A  >  G and g.278–295del) were identified in the 5'-UTR and signal peptide region. Furthermore, eight haplotypes were identified based on the four SNPs. The H8 was the most common haplotype with a frequency of more than 31 %. The four SNPs and their haplotype combinations were shown to be significantly associated with body weight at 6–10 weeks of age (P < 0. 05 or P < 0. 01) and abdominal fat percentage (AFP) (P < 0. 05 or P < 0. 01). Remarkably, the H1H1 diplotype had an effect on increasing body weight and decreasing AFP from the 6th to the 10th weeks of age. However, increasing positive effects of the H5H8 diplotype were observed for both body weight and AFP. This study suggests that the VLDLR gene plays an important role in the regulation of body weight and fat-related traits and may serve as a potential marker for the marker-assisted selection program during duck breeding.
Experimental determination of Henry's law constants of difluoromethane (HFC-32) and the salting-out effects in aqueous salt solutions relevant to seawater
Authors: Kutsuna Shuzo
Published: June 2017

Abstract. Gas-to-water equilibrium coefficients, KeqS (in M atm−1), of difluoromethane (CH2F2), a hydrofluorocarbon refrigerant (HFC-32), in aqueous salt solutions relevant to seawater were determined over a temperature (T) range from 276 to 313 K and a salinity (S) range up to 51 ‰ by means of an inert-gas stripping method. From the van't Hoff equation, the KeqS value in water, which corresponds to the Henry's law constant (KH), at 298 K was determined to be 0.065 M atm−1. The salinity dependence of KeqS (the salting-out effect), ln(KH∕KeqS), did not obey the Sechenov equation but was proportional to S0. 5. Overall, the KeqS(T) value was expressed by ln(KeqS(T))  =  −49.71 + (77.70 − 0.134  ×  S0. 5)  ×  (100∕T) + 19.14  ×  ln(T∕100). By using this equation in a lower-tropospheric semi-hemisphere (30–90 °S) of the Advanced Global Atmospheric Gases Experiment (AGAGE) 12-box model, we estimated that 1 to 4 % of the atmospheric burden of CH2F2 resided in the ocean mixed layer and that this percentage was at least 4 % in the winter; dissolution of CH2F2 in the ocean may partially influence estimates of CH2F2 emissions from long-term observational data of atmospheric CH2F2 concentrations.
Impact of the 4 April 2014 Saharan dust outbreak on the photovoltaic power generation in Germany

Published: June 2017

Abstract. The importance for reliable forecasts of incoming solar radiation is growing rapidly, especially for those countries with an increasing share in photovoltaic (PV) power production. The reliability of solar radiation forecasts depends mainly on the representation of clouds and aerosol particles absorbing and scattering radiation. Especially under extreme aerosol conditions, numerical weather prediction has a systematic bias in the solar radiation forecast. This is caused by the design of numerical weather prediction models, which typically account for the direct impact of aerosol particles on radiation using climatological mean values and the impact on cloud formation assuming spatially and temporally homogeneous aerosol concentrations. These model deficiencies in turn can lead to significant economic losses under extreme aerosol conditions. For Germany, Saharan dust outbreaks occurring 5 to 15 times per year for several days each are prominent examples for conditions, under which numerical weather prediction struggles to forecast solar radiation adequately. We investigate the impact of mineral dust on the PV power generation during a Saharan dust outbreak over Germany at 4 April 2014 using ICON-ART, which is the current German numerical weather prediction model extended by modules accounting for trace substances and related feedback processes. We find an overall improvement of the PV power forecast for 65 % of the pyranometer stations in Germany. Of the nine stations with very high differences between forecast and measurement, eight stations show an improvement. Furthermore, we quantify the direct radiative effects and indirect radiative effects of mineral dust. For our study, direct effects account for 64 %, indirect effects for 20 % and synergistic interaction effects for 16 % of the differences between the forecast including mineral dust radiative effects and the forecast neglecting mineral dust.
Evaluation of statistical methods for quantifying fractal scaling in
water quality time series with irregular sampling
Authors: Zhang Qian , Harman Ciaran J. , Kirchner James W.
Published: June 2017

Abstract. River water-quality time series often exhibit fractal scaling, which here refers to autocorrelation that decays as a power law over some range of scales. Fractal scaling presents challenges to the identification of deterministic trends, but traditional methods for estimating spectral slope (β) or other equivalent scaling parameters (e.g., Hurst exponent) are generally inapplicable to irregularly sampled data. Here we consider two types of estimation approaches for irregularly sampled data and evaluate their performance using synthetic time series. These time series were generated such that (1) they exhibit a wide range of prescribed fractal scaling behaviors, ranging from white noise (β = 0) to Brown noise (β = 2), and (2) their sampling gap intervals mimic the sampling irregularity (as quantified by both the skewness and mean of gap-interval lengths) in real water-quality data. The results suggest that none of the existing methods fully account for the effects of sampling irregularity on β estimation. First, the results illustrate the danger of using interpolation for gap filling when examining auto-correlation, as the interpolation methods consistently under-estimate or over-estimate β under a wide range of prescribed β values and gap distributions. Second, the long-established Lomb-Scargle spectral method also consistently under-estimates β. A modified form, using only the lowest 5 % of the frequencies for spectral slope estimation, has very poor precision, although the overall bias is small. Third, a recent wavelet-based method, coupled with an aliasing filter, generally has the smallest bias and root-mean-squared error among all methods for a wide range of prescribed β values and gap distributions. The aliasing method, however, does not itself account for sampling irregularity, and this introduces some bias in the result. Nonetheless, the wavelet method is recommended for estimating β in irregular time series until improved methods are developed. Finally, all methods' performances depend strongly on the sampling irregularity, highlighting that the accuracy and precision of each method are data-specific. Accurately quantifying the strength of fractal scaling in irregular water-quality time series remains an unresolved challenge for the hydrologic community and for other disciplines that must grapple with irregular sampling.
Reformular, relanzar, reorganizar o, ¿Transformar Honduras?

En el diario vivir de los hondureños es muy común identificar a las personas a partir de sus posicionamientos en derredor de aspectos que tienen que ver con los problemas que atañen al país y no como quieren algunos hacernos creer que en nuestro país la identidad de los ciudadanos gravita alrededor de su militancia en los partidos tradicionales. Esa pretendida identificación además de ser una falsa premisa, constituye más bien un propósito diversionista que no busca otra cosa que no sea la distracción de los grandes objetivos hacia los que debe orientarse la nación. Los recientes acontecimientos políticos que sacudieron la conciencia nacional han servido para que la demarcación no deje lugar a dudas, puesto que en definición del golpe de estado que depuso a las autoridades legítimas del país, ha estado implícito el tránsito de cualquier eufemismo teórico a una práctica o realidad que no se puede ocultar y del lado del golpe se han alineado hasta los más acérrimos enemigos de las mas tibias reformas, además de aquellos tradicionales conservadores, que en concordancia con sus intereses, se aferran a un status que se desmorona en pedazos, como resultado de su agotamiento histórico..
Academic persistence among nursing students: A concept analysis
Authors: Kennel Kimberly D. , Ward-Smith Peggy
Published: June 2017

Background: Persistence, in academic settings, has been identified as a critical variable for success. Different than retention and attrition, persistence, as a personal characteristic, describes the student who progresses, despite opposition or importunity.Methods: The Walker and Avant framework was used to guide the analysis of the concept of academic persistence, specifically as it applies to nursing education.Results: Barriers to persisting, among nursing students, include academic and personal variables. As faculty, we are concerned with and responsible to provide interventions that address academic barriers to persistence; there is little we can, or should do with personal barriers.Conclusions: Being able to identify the difference between academic and personal variables is the initial step in providing appropriate, and valued interventions.

O Chiado De Outrora, O Chiado de Agora: Difusão da Moda, Urbanização e Revitalização de Zonas Históricas
Authors:   Universidade de Lisboa, Cardim Valter Carlos
Published: June 2017

Ao estudarmos a Moda e o seu desenvolvimento histórico em Portugal nos séculos XIX e XX, a nível do desenvolvimento de uma tese de doutoramento, verificou-se que o Chiado, bairro situado em Lisboa, foi de extrema importância para a disseminação da Moda em Portugal. O Chiado, no passado, era frequentado pelas classes mais abastadas de Lisboa, pela nobreza, aristocracia, burgueses, intelectuais e políticos. Ao longo dos anos passou por diversas fases: no passado como centro de difusão do luxo; após a Revolução de 25 de Abril de 1974 e ao grande incêndio que ali ocorreu em 1988, pelo declínio, e, recentemente, devido a revitalização urbana ali realizada, a um renascimento. O Chiado não deixa de ter, apesar da abertura de vários Centros Comerciais, da mudança das principais marcas de luxo do Chiado e redondezas para a Avenida da Liberdade, uma importância ímpar para os seguidores da Moda e os amantes do luxo.

The present research was conducted to evaluate the M2 wheat mutant population for yield and its contributing traits. The experiment was conducted at Nuclear Institute of Agriculture (NIA), Tando Jam, during rabi season 2015-2016, in split plot design with three replications. Two wheat varieties (T. D-1 and ESW-9525) were treated with different levelsof gamma rays (150Gy, 200Gy, 250Gy, 300Gy and control) from NIMRA (Nuclear Institute of Medicine and Radiotherapy), Jamshoro. The mutated plants were evaluated along with parental lines (control) for yield and its contributing traits under field conditions. Genetic parameters viz., mean performance, were calculated such as days to 75 % heading, days to 75 % maturity, plant height (cm), spikelets spike-1 and spike length (cm). Mean square showed that there were significant differences between wheat varieties for days to 75% heading, days to 75% maturity, plant height (cm), spikelets spike-1 and spike length (cm) treatments of gamma radiation caused significant variation in all the traits studied. The interaction between treatments × varieties showed highly significant differences for the entire traits indicating that varieties responded differently for radiation treatments. Mean performance forspike length indicated that the longer spike (11.52 cm) was observed in T.D-1 at treatment four (T4=250 Gy) and treatment two (150 Gy) in ESW-9525 . Whereas, the shortest spike (10. 83 cm) wasobserved in the variety T.D-1 under control. The results regarding maximum mean performance ofspikelets spike-1 (24. 74) were recorded in ESW-9525 under treatment five at 300 Gy whereas the minimumvalue forspikelets spike-1 (18.76) were observed in T.D-1 under T1 (18.76) at 0 Gy and T4 at 250 Gy.

Published: June 2017

Les cardiopathies congénitales (CC) sont les malformations les plus fréquentes chez le nouveau-né. La littérature des dernières décennies a mis en évidence des retards développementaux fréquents dans cette population, notamment sur le plan de la motricité, du fonctionnement intellectuel global, du langage, de la mémoire, de l’attention et des fonctions exécutives. Le présent article propose une revue de littérature concernant la physiopathologie de ces retards et les facteurs susceptibles d’en augmenter les risques. Les profils neuropsychologiques associés à la présence d’une CC, ainsi que leur impact sur les acquisitions scolaires, l’adaptation comportementale et la qualité de vie seront présentés.

L’objectif de cet article est de décrire les différentes atteintes des personnes ayant une DI et de suggérer des pistes d’interventions pour chacun des types d’atteintes. Les connaissances actuelles sur l’efficacité de ces interventions chez les personnes qui présentent une DI seront décrites.
EXPÉRIENCE D’AIDANT DES PROCHES DE PERSONNES ATTEINTES D’UN TROUBLE DE LA CONDUITE ALIMENTAIRE : RECENSION CRITIQUE DE LA LITTÉRATURE
Authors: Blondin Soline , Meilleur Dominique
Published: June 2017

L’objectif de cet article est de dresser un portrait de l’état des connaissances des études qualitatives et quantitatives portant sur l’expérience subjective des aidants naturels de personnes atteintes d’un trouble de la conduite alimentaire. L’analyse des résultats des 26 articles sélectionnés fait ressortir trois grands thèmes : l’expérience subjective du rôle d’aidant, la perception de la maladie, et la perception de l’aide offerte et des professionnels. Les études qualitatives et quantitatives s’accordent sur le fait que prendre soin d’une personne souffrant d’un TCA est une expérience difficile qui entraîne des conséquences importantes au niveau émotionnel. Les résultats de la recension sont discutés et des applications cliniques sont proposées. Des orientations pour des recherches futures sont suggérées.

Published: June 2017

Depuis leur création en 2004, les sites de socialisation virtuelle sont devenus des plateformes de communication privilégiées par plusieurs internautes. La présente étude vise à examiner les liens entre l’utilisation des sites de socialisation virtuelle et diverses variables intrapersonnelles et relationnelles. Dans la présente étude, 822 participants en relation de couple ont répondu à un questionnaire sur Internet. Les résultats indiquent que plus les internautes affichent des taux élevés d’attachement anxieux, de névrosisme et de cyberinfidélité, plus ils consacrent de temps à leurs activités sur les sites de socialisation virtuelle. Les résultats des analyses de régression multiple soulignent que le nombre d’amis sur Facebook, ainsi que les problèmes reliés à l’utilisation de Facebook contribuent significativement à l’explication de la variance associée à l’ajustement conjugal et la satisfaction sexuelle.

Published: June 2017

L’objectif du présent projet était d’examiner les associations entre le soutien de la famille et des amis, le rapport à l’orientation sexuelle, la détresse, le bien-être et le fonctionnement scolaire de jeunes lesbiennes, gais et bisexuel(le)s québécois (n = 29). Les résultats ont révélé que le soutien de la famille était négativement associé au rapport conflictuel à l’orientation sexuelle ainsi qu’à la détresse et positivement associé au bien-être. Le soutien des amis était associé négativement à la peur de la violence homophobe et positivement au bien-être. Le rapport conflictuel à l’orientation sexuelle était associé positivement à la détresse et négativement au bien-être. Le soutien des enseignants était positivement associé à la motivation scolaire et négativement à la violence homophobe, cette dernière étant négativement associée à la motivation.
FONCTIONNEMENT RÉFLEXIF DE LA MÈRE ET ATTACHEMENT DE L’ENFANT : UNE ÉTUDE PROSPECTIVE DES LIENS AVEC LA SENSIBILITÉ ET L’ORIENTATION MENTALE MATERNELLE
Authors: Bérubé-Beaulieu Éva , Ensink Karin , Normandin Lina
Published: June 2017

L'objectif de l’étude est d’examiner l’association du fonctionnement réflexif (FR) et de l’orientation mentale maternelle (OMM) à l’attachement de l’enfant, par l’entremise de la sensibilité maternelle. Le FR a été évalué grâce à l’entrevue d’attachement chez l’adulte (AAI), alors que l’OMM et la sensibilité l’ont été lors de situations d’interaction. La situation étrangère, effectuée auprès de 88 dyades mère-enfant, a permis de mesurer l’attachement de l’enfant. Les analyses acheminatoires montrent que le lien entre le FR et l’attachement de l’enfant est médié par la sensibilité. La sensibilité médie également la relation entre l’OMM approprié et l’attachement de l’enfant. Les implications quant aux interventions possibles sont discutées.

Published: June 2017

Les capacités de mentalisation des victimes d’agression sexuelle vécue durant l’enfance (ASE) sont méconnues. L’étude propose de mesurer et décrire les capacités de mentalisation spécifique au trauma chez 30 adultes ayant subi des ASE. Ces capacités sont codifiées à partir d’une entrevue sur les dévoilements de l’ASE. Quarante pourcent des participants présentent des capacités de mentalisation déficitaires, 33 % des capacités de mentalisation rudimentaires et 28 % une mentalisation efficiente. Des exemples de manifestations de mentalisation sont décrits. Ces résultats permettent de mieux comprendre les capacités de mentalisation des victimes à l’égard des expériences traumatiques. Les implications cliniques sont discutées.

La capacité de mentalisation du thérapeute, habileté lui permettant de comprendre le monde interne du patient et le sien en contexte clinique, est un processus à la fois cognitif et affectif pouvant être opérationnalisé à l’aide du construit d’Activité Mentale du Thérapeute (AM-T). La grille d’AM-T comprend trois échelles mesurant les modes rationnel/objectif, réactif/impulsif et réflexif/mentalisant. Les AM-T de 107 thérapeutes expérimentés et en formation ont été mesurées. Trois profils distincts d’AM-T ont été identifiés. Une différence en ce qui a trait à l’expérience a été retrouvée entre les profils. Les implications théoriques et cliniques de ces profils seront discutées.
Apports cliniques et projectifs À la comprÉhension du passage À l’acte SUICIDAIRE DE JEUNES HOMOSEXUELS
Authors: Barrattini Anaïs , Mazoyer Anne-Valérie
Published: June 2017

L’objet de cet article est de contribuer à une réflexion autour de la prise en charge des actes suicidaires de jeunes homosexuels. Dans un premier temps, nous proposerons une brève présentation de quelques études épidémiologiques, permettant de saisir la prédominance du recours à l’acte suicidaire par notre population d’étude. Puis, à travers la présentation d’une situation clinique où se nouent traumas précoces, actes suicidaires et homosexualité, étayée par l’apport du test du Rorschach, nous proposons une conception de l’acte suicidaire orientant notre travail de prise en charge thérapeutique de ces jeunes. En somme, la tentative de suicide, ainsi que l’homosexualité semblent être en réalité des aménagements des traumas antérieurs vécus.
