First record of the invasive bumblebee <i>Bombus terrestris</i> (Hymenoptera: Apidae) on Navarino Island, southern Chile (55°S)
Authors: Rendoll-Carcamo Javier Alejandro , Contador Tamara Andrea , Saavedra Lorena , Montalva José 
Published: July 2017

As the volume of global trade expands, so does the risk of alien species reaching new regions. Bombus (Bombus) terrestris (Linnaeus) (Hymenoptera: Apidae) is a bumble bee traded internationally for crop pollination and is now considered an invasive species in New Zealand, Japan, and throughout South America. We newly document its presence on Navarino Island, Cape Horn, Biosphere Reserve, Chile (55°S), the southernmost locality reached by this species to date.
Single Machine Scheduling to Minimize Weighted Sum of Completion Times Added with the Maximum Tardiness - A Branch and Bound Approach
Authors: Ramadan Ayda 
Published: July 2017

This paper considers the problem of scheduling n jobs on a single machine to minimize total weighted completion times and the maximum tardiness. A branch and bound algorithm is proposed to find optimal schedule. Our lower bound based on the late and early jobs. Computational experience on problems with to 60 jobs for a special case and 50 jobs for a general case, where {he previous works solve the problem up to 50 and 40 jobs for special and general case respectively. This indicates that the proposed algorithm is superior to other known algorithms.

Published: July 2017

Background:
It has been shown that theta (6-10 Hz) and delta (1-6 Hz) ongoing
electroencephalographic (EEG) rhythms revealed variations in the cortical arousal in C57 Wild Type
(WT) mice during cage exploration (active condition) compared to awake quiet behavior (passive
condition; IMI PharmaCog project, www.pharmacog.eu).

Objective:
The objective was to test if these EEG rhythms might be abnormal in old PDAPP mice
modeling Alzheimer's disease (AD) with a hAPP Indiana V717F mutation (They show abnormal neural
transmission, cognitive deficits, and brain accumulation of Aβ1-42).

Methods:
Ongoing EEG rhythms were recorded by a frontoparietal bipolar channel in 15 PDAPP and 23
WT C57 male mice (mean age of 22.8 months ±0.4 and 0.3 standard error, respectively). EEG absolute
power (density) was calculated. Frequency and amplitude of individual delta and theta frequency (IDF
and ITF) peaks were considered during passive and active states in the wakefulness.

Results:
Compared with the WT group, the PDAPP group showed higher frequency of the IDF during
the passive condition and lower frequency of the ITF during the active state. Furthermore, the WT but
not PDAPP group showed significant changes in the frontoparietal EEG power (IDF, ITF) during active
over passive state.

Conclusion:
PDAPP mice were characterized by less changes in the brain arousal during an active state
as revealed by frontoparietal EEG rhythms. Future studies will have to cross-validate the present results
on large animal groups, clarify the neurophysiological underpinning of the effect, and test if the disease
modifying drugs against AD amyloidosis normalize those candiate EEG biomarkers in PDAPP mice
Optimum HPLC Conditions for Determination of Dibucaine HCL, Fluocortolone Pivalate and Fluocortolone Caproate by Using Experimental Design
Authors: Aşçı Bürge , Koç Mesut 
Published: July 2017

Introduction:This paper presents the development and validation of a novel, fast, sensitive and accurate high performance liquid chromatography (HPLC) method for the simultaneous quantitative determination of dibucaine HCl, fluocortolone pivalate and fluocortolone caproate in pharmaceutical preparations.Experiment:Development of the chromatographic method was based on an experimental design approach. A five-level-three-factor central composite design requiring 20 experiments in this optimization study was performed in order to evaluate the effects of three independent variances including mobile phase ratio, flow rate and amount of acid in the mobile phase.Conclusion:The optimum composition for mobile phase was found as a methanol:water:acetic acid mixture at 71.6 : 26.4 : 2 (v/v/v) ratio and optimum separation was acquired by isocratic elution with a flow rate of 1.3 mL/min. The analytes were detected using a UV detector at 240 nm. The developed method was validated in terms of linearity, precision, accuracy, limit of detection/quantitation and solution stability and successfully applied to the determination of dibucaine HCl, fluocortolone pivalate and fluocortolone caproate in pharmaceutical topical formulations such as suppositories and ointments.

Published: July 2017

Ekosistem mangrove memiliki kemampuan menyerap CO2 lebih tinggi dibandingkan dengan vegetasi tumbuhan lainnya. Namun upaya pengelolaannya sebagai kawasan penyimpan stok karbon masih belum maksimal. Kota Makassar memiliki Sungai Tallo yang sepanjang bantarannya ditumbuhi oleh vegetasi mangrove dan sangat potensial untuk dikelola sebagai ruang terbuka hijau. Hasil pengamatan menunjukkan bahwa Sungai Tallo terletak tepat di tengah kota Makassar dan sepanjang bantaran sungai didominasi oleh spesies Nypa fruticans dengan jumlah 18.514 pohon dan kerapatan 4.256 pohon/ha, menyimpan karbon sebesar 21,82 ton C/ha, menyerap 80,02 ton CO2/ha. Spesies dominan kedua adalah Rhizophora mucronata dengan jumlah 8.492 pohon dan kerapatan 2.352 pohon/ha, menyimpan karbon sebesar 19,94 ton C/ha, menyerap 73,13 ton CO2/ha. Spesies dominan ketiga yaitu Avicennia alba dengan jumlah 2.421 pohon dan kerapatan 3.228 pohon/ha, menyimpan karbon sebesar 53,96 ton C/ha, menyerap 197,87 ton CO2/ha. Nilai kerapatan dan kemampuan serapan mangrove tersebut sangat sesuai untuk dikelola pada ruang terbuka hijau penyuplai udara segar dan penyerap CO2.Stock Estimation and Carbon Absorption of Mangrove in Tallo River, MakassarAbstractThe mangrove ecosystem has a higher ability of CO2 absorption than other vegetations. However, the effort to establish the mangrove to be a carbon stock area has not been achieved. Makassar has Tallo River, covered with mangrove vegetation along its riverbank, which is potent to be managed as a green open space. The observations indicated that Tallo River was located in the center part of Makassar city and was dominated by Nypa fruticans along the riverbanks in 18,514 trees and a density of 4,256 trees/ha, stored carbon of 21.82 tons C/ha, and absorbs 80.02 tons CO2/ha. Rhizophora mucronata was the second dominant species in 8.492 trees and density of 2,352 trees/ha, stored carbon of 19.94 tons C/ha, and absorbs 73.13 tons CO2/ha. The third dominant species was Avicennia alba in 2,421 trees and density of 3,228 trees/ha, stored carbon of 263.85 tons C/ha, and absorbs 197.89 tons CO2/ha. The density and ability to absorb values of the mangrove is highly suitable to be managed for a green open space to supply fresh air and CO2.
Directions of Development of Intelligent Real Time Video Systems

Published: July 2017

Real time video systems play a significant role in many fields of science and technology. The range of their applications is constantly increasing together with requirements to them, especially it concerns to real time video systems with the feedbacks. Conventional fundamentals and principles of real-time video systems construction are extremely redundant and do not take into consideration the peculiarities of real time processing and tasks, therefore they do not meet the system requirements neither in technical plan nor in informational and methodical one. Therefore, the purpose of this research is to increase responsiveness, productivity and effectiveness of real time video systems with a feedback during the operation with the high-speed objects and dynamic processes. The human visual analyzer is considered as a prototype for the construction of intelligent real time video systems. Fundamental functions, structural and physical peculiarities of adaptation and processes taking place in a visual analyzer relating to the information processing, are considered. High selectivity of information perception and wide parallelism of information processing on the retinal neuron layers and on the higher brain levels are most important peculiarities of a visual analyzer for systems with the feedback. The paper considers two directions of development of intelligent real time video systems. First direction based on increasing intellectuality of video systems at the cost of development of new information and dynamic models for video information perception processes, principles of control and reading parameters of video information from the sensor, adapting them to the requirements of concrete task, and combining of input processes with data processing. Second direction is associated with the development of new architectures for parallel perception and level-based processing of information directly on a video sensor matrix. The principles of annular and linear structures on the neurons layers, of close-range interaction and specialization of layers, are used to simplify the neuron network.
Learners’ perceptions of instructor feedback in e-learning courses – findings from HBMSU, United Arab Emirates
Authors: Awofeso Niyi , Bamidele Moyosola 
Published: July 2017

Instructor feedback is constructive and specific information provided by an instructor to a learner on his or her course work and/or class contributions in relation to the course objectives and expectations. Effective instructor feedback is particularly important in online learning as learners are more likely to withdraw from online learning environments due to delayed, or inadequate feedback, compared with students enrolled in physical classes. Not all learners are equally active, and there are indeed learners who hardly take an active part in online course activities -the so-called lurkers. Courteous instructor feedback to such learners on their limited participation has been shown to improve learners’ participation in online courses. Diligent learners engaged in online learning programs expect feedback to be contextual, supportive, constructive, timely, substantive, summative and formative. This study examined the perceptions of 66 undergraduate and postgraduate learners on feedback provided in eight online courses facilitated by the same instructor at the School of Health and Environmental Studies, Hamdan Bin Mohammed Smart University, Dubai, UAE between August 2014 and December 2015. Data collection from learners was anonymized and participation was voluntary.
The survey sought to elicit learners’ perceptions on the extent to which feedback provided in specified courses were motivational, timely, frequent, supportive, and individualized. A polytomous Rasch model was utilized to analyze the data with Winsteps and STATA. Analysis of the 20 survey questions revealed a real person reliability of 0.82 and a Cronbach Alpha test reliability of 0.96, suggesting that the scale discriminates well between the persons. The real item separation reliability of 0.77 suggests that the questions are reliable in measuring the specified items. Descriptive analyses revealed general agreement among the majority of learners on the effectiveness of feedback provided by the instructor, although Infit and Outfit Z-standard deviation statistics revealed two questions with unexpected rare (i.e. “mostly disagree” or “completely disagree”) extremes in several learners’ responses. Unlike single questions related to learner feedback in most Student Perception of Teaching Surveys, this survey instrument comprehensively explores the dimensions of instructor feedback, aspects of which may not be previously known to learners or instructors. Our results indicate that systematic collection and analysis of learners’ feedback comments have a strong potential to enhance feedback competencies of course facilitators, as well as provide a common platform for both learners and course facilitators vis-à-vis the diverse objectives of instructor feedback.

OBJECTIVE
Insulin increases glucose disposal in part by enhancing microvascular blood flow (MBF) and substrate delivery to myocytes. Insulin’s microvascular action is impaired with insulin resistance and type 2 diabetes. Resistance training (RT) improves glycemic control and insulin sensitivity, but whether this improvement is linked to augmented skeletal muscle microvascular responses in type 2 diabetes is unknown.

RESEARCH DESIGN AND METHODS
Seventeen (11 male and 6 female; 52 ± 2 years old) sedentary patients with type 2 diabetes underwent 6 weeks of whole-body RT. Before and after RT, participants who fasted overnight had clinical chemistries measured (lipids, glucose, HbA1c, insulin, and advanced glycation end products) and underwent an oral glucose challenge (OGC) (50 g × 2 h). Forearm muscle MBF was assessed by contrast-enhanced ultrasound, skin MBF by laser Doppler flowmetry, and brachial artery flow by Doppler ultrasound at baseline and 60 min post-OGC. A whole-body DEXA scan before and after RT assessed body composition.

RESULTS
After RT, muscle MBF response to the OGC increased, while skin microvascular responses were unchanged. These microvascular adaptations were accompanied by improved glycemic control (fasting blood glucose, HbA1c, and glucose area under the curve [AUC] during OGC) and increased lean body mass and reductions in fasting plasma triglyceride, total cholesterol, advanced glycation end products, and total body fat. Changes in muscle MBF response after RT significantly correlated with reductions in fasting blood glucose, HbA1c, and OGC AUC with adjustment for age, sex, % body fat, and % lean mass.

CONCLUSIONS
RT improves OGC-stimulated muscle MBF and glycemic control concomitantly, suggesting that MBF plays a role in improved glycemic control from RT.
Maltraitance infantile et inertie des situations à risque : essai de conceptualisation des résistances psychologiques parentales
Authors: Lafortune David , Gilbert Sophie , Lavallée Geneviève , Lussier Véronique 
Published: July 2017

Certains processus psychologiques, chez les parents à risque de maltraitance, entraveraient l’alliance et les progrès thérapeutiques ; toutefois, ces mécanismes n’ont pas encore été clairement identifiés à ce jour, de même que leurs liens pressentis avec l’histoire infantile souvent traumatique de ces parents. Cette étude exploratoire consistait en l’utilisation – supervisée – du génogramme libre dans le suivi clinique de huit mères en difficulté, rapportant avoir subi des expériences de maltraitance. Les données récoltées au fil des entretiens et analysées dans une perspective conceptuelle, ont permis de cerner certains processus psychologiques défensifs. Ceux-ci paraissent érigés contre la révélation et l’élaboration des composantes affectives douloureuses rattachées à l’histoire du parent, obstruant, dans l’intervention, l’abord des difficultés affaiblissant l’investissement de la parentalité.
Le rôle Super militibus de la seigneurie de Picquigny (1192/1199) : l’écrit au secours d’une société châtelaine en crise ?
Authors: Nieus Jean-François 
Published: July 2017

Le plus ancien document des archives des seigneurs de Picquigny (Fr., dép. Somme) est un rouleau intitulé Super militibus , datable des années 1190, dans lequel sont énumérés les noms, les services et les fiefs de 125 vassaux liés par l’hommage au sire Enguerran (Paris, AN, R 1 675/1). De cet écrit exceptionnel, rapidement analysé en 1968 par Robert Fossier, qui y a vu l’indice d’une féodalisation tardive et un peu artificielle de l’espace picard, la présente étude propose une interprétation nouvelle, diamétralement opposée à celle du regretté médiéviste. Le rôle Super militibus , très focalisé sur les services de garnison dus au sire par ses principaux vassaux, en particulier par un groupe d’une trentaine de gardiens « permanents » de la forteresse de Picquigny, témoigne en réalité de l’ancienneté de cette organisation militaire, de sa déliquescence après le milieu du xii e siècle et des efforts déployés par l’entourage du sire pour en sauvegarder les principales modalités. Le recours à l’écrit – assez neuf en milieu seigneurial – vise ici à figer un état de choses traditionnel, non à infléchir le réel dans un sens nouveau. Une transcription du rôle Super militibus est proposée en annexe.

Abstract
Drug hypersensitivity involves the activation of T cells in an HLA allele–restricted manner. Because the majority of individuals who carry HLA risk alleles do not develop hypersensitivity, other parameters must control development of the drug-specific T cell response. Thus, we have used a T cell–priming assay and nitroso sulfamethoxazole (SMX-NO) as a model Ag to investigate the activation of specific TCR Vβ subtypes, the impact of programmed death -1 (PD-1), CTL-associated protein 4 (CTLA4), and T cell Ig and mucin domain protein-3 (TIM-3) coinhibitory signaling on activation of naive and memory T cells, and the ability of regulatory T cells (Tregs) to prevent responses. An expansion of the TCR repertoire was observed for nine Vβ subtypes, whereas spectratyping revealed that SMX-NO–specific T cell responses are controlled by public TCRs present in all individuals alongside private TCR repertoires specific to each individual. We proceeded to evaluate the extent to which the activation of these TCR Vβ–restricted Ag-specific T cell responses is governed by regulatory signals. Blockade of PD-L1/CTLA4 signaling dampened activation of SMX-NO–specific naive and memory T cells, whereas blockade of TIM-3 produced no effect. Programmed death-1, CTLA4, and TIM-3 displayed discrete expression profiles during drug-induced T cell activation, and expression of each receptor was enhanced on dividing T cells. Because these receptors are also expressed on Tregs, Treg-mediated suppression of SMX-NO–induced T cell activation was investigated. Tregs significantly dampened the priming of T cells. In conclusion, our findings demonstrate that distinct TCR Vβ subtypes, dysregulation of coinhibitory signaling pathways, and dysfunctional Tregs may influence predisposition to hypersensitivity.
Características epistemológicas de publicações científicas em Contabilidade: evidências de um cenário produtivista
Authors: Costa Flaviano , Martins Gilberto De Andrade 
Published: July 2017

O objetivo desta investigação foi levantar e analisar as características epistemológicas em publicações científicas que sinalizam um cenário de produtivismo acadêmico no campo científico contábil, com base na análise de artigos de um periódico considerado de alta qualidade na classificação do Sistema Qualis da CAPES. Trata-se de um estudo documental, com uma amostra de 43 artigos. Os dados foram analisados com emprego de análise de conteúdo. As análises epistemológicas evidenciaram uma preferência por temáticas envolvendo a Contabilidade para usuários externos e mercado de capitais, privilegiando a utilização de dados secundários, por meio de pesquisas documentais. Constatou-se a presença unânime de estudos positivistas e a utilização de modelos econométricos para explicar a realidade observada sem teoria para embasar esses modelos. Por conseguinte, concluiu-se que o campo científico contábil permanece sem modificações teóricas devido ao produtivismo que motivou a criação de uma espécie de “formato ideal” legitimado, institucionalizado e difícil de modificar.
Homens autores de violência contra mulheres: políticas públicas, desafios e intervenções possíveis na América Latina e Portugal
Authors: F. Toneli Maria Juracy , Beiras Adriano , Ried Juliana 
Published: July 2017

A partir de pesquisas desenvolvidas no contexto da América Latina e Portugal que mapearam programas de atendimento a homens autores de violência contra mulheres, este artigo busca problematizar como homens autores de violência têm sido visibilizados pelas políticas públicas. São iniciativas de entidades não governamentais, em sua grande maioria, que desenvolvem programas para o atendimento ao homem, embora tenha crescido no Brasil intervenções governamentais depois da criação da Lei Maria da Penha. Em Portugal, dos quatro programas visitados, três deles estão vinculados a universidades e outro a um hospital. Ao esboçar alguns dos enfrentamentos para atender a demanda masculina, o êxito dos programas precisa ser salientado, ao propor atendimentos educativos reflexivos e/ou terapêuticos. Através da elaboração e fortalecimento de políticas públicas e de intervenções que deem visibilidade aos homens autores de violência amplia-se a possibilidade de promover mudanças neste cenário.

Authors: Gavilan Diana , Martínez-Navarro Gema , Fernández-Lores Susana 
Published: July 2017

Internet ha revolucionado el sector turístico desde el punto de vista del consumidor y la empresa. La información actualmente es abundante y accesible y el viajero, cada vez más tecnológico, se ha convertido en prescriptor. Así, evaluaciones y comentarios hechos por usuarios anónimos en los sites de alojamientos representan una forma de influencia de gran impacto en la toma de decisiones que ha transformado los tradicionales modelos de comunicación de las empresas. Este trabajo estudia la influencia social que ejercen las valoraciones numéricas y los comentarios en el proceso de elección de alojamientos turísticos, teniendo en cuenta la susceptibilidad del propio usuario a la información que procede de otras personas. Para ello se ha realizado un experimento cuyas conclusiones revelan que las evaluaciones constituyen un factor crítico en la decisión, pero están supeditadas al volumen de comentarios y que la susceptibilidad del usuario a la influencia social modera este proceso
