Authors: Soares de Oliveira Sandra Nivia 
Published: February 2019

Neste trabalho, toma-se o processo de construção da identidade do quilombo de Mangal e Barro Vermelho, situado no Oeste da Bahia-Brasil, compreendendo que sua história e seu processo de construção da identidade podem contribuir para a formação de professores, no debate sobre a educação escolar quilombola e na efetivação de suas diretrizes, enten-dendo quilombo como uma categoria dinâmica que se atualiza no tempo, ressaltando os diversos caminhos para a construção da identidade quilombola e a necessidade de atentar a essa questão nas discussões sobre a educação de quilombolas. Este trabalho toma como referência os dados de pesquisa de mestrado, ancorada nos aportes teórico-metodológicos da história oral, e a experiência da autora na formação de professores.
A formação do pedagogo na educação a distância: alguns dilemas e possibilidades
Authors: Santos Adriana Regina de Jesus , Gonçalves José Alexandre , Costa Rogério Da 
Published: February 2019

O referido artigo tem como objetivos compreender o perfil da formação do pedagogo e conhecer as diferenças de intencionalidade em relação a “Objetivos” e “ Perfil de Egresso” que os programas pretendem formar, tendo como parâmetro dois cursos de Pedagogia, ofertados na modalidade de EaD, por uma instituição pública e outra privada, localizados na cidade de Telêmaco Borba, PR, bem como analisar as percepções dos acadêmicos em relação a sua formação no que tange ao compromisso ético-profissional. Como procedimentos metodológicos adotamos a revisão de literatura, levantamento documental e trabalho de campo. Na revisão de literatura, tivemos como suporte teórico alguns autores, tais como: Freire (1983), Giroux (1992), Lessa (2012), Lukács (2013), Nóvoa (1992), Pimenta (1999), Saviani (2005), entre outros; na pesquisa documental analisamos dois projetos pedagógicos dos referidos cursos e como trabalho de campo aplicamos um questionário para coleta de dados junto aos estudantes das duas instituições. Ao término do estudo, constatou-se certa ambiguidade no que se refere à formação do perfil do pedagogo que se almeja formar, dado que na faculdade particular o foco estava voltado à empregabilidade desse profissional no mercado de trabalho e na instituição pública percebeu-se a preocupação com a formação ontológica, ética e política do futuro profissional pedagogo.

Auto-apprentissage et bibliothèques
Authors: Dumouchel Bernard 
Published: February 2019

Les méthodes d’auto-apprentissage suscitent de plus en plus d’intérêt depuis qu’on entrevoit leurs bénéfices et surtout qu’on sait qu’un nombre croissant d’adultes les adoptent. Dans un premier temps, l’auteur veut donner une définition du concept qui sous-tend ces méthodes, avant d’en aborder l’évolution historique. Par des illustrations d’auto-apprentissage tirées du milieu éducatif et à travers le processus de l’auto-apprentissage, il essaie de cerner l’aide recherchée par l’auto-apprenant. Passant ensuite de la théorie à la pratique en se servant des bibliothèques comme champ d’application, il parle de l’expérience américaine de l’« Adult Independant Learning Project », en tirant une description du rôle du bibliothécaire comme facilitateur et un aperçu de l’entraînement nécessaire à l’accomplissement de ce rôle, pour terminer par une analyse des possibilités d’implantation de tels projets dans des milieux comme les cégeps au Québec ou les collèges communautaires en Ontario.
L’évaluation de l’efficacité de la bibliothèque : cadre théorique et méthodologique
Authors: Cossette André 
Published: February 2019

L’auteur propose un cadre théorique et méthodologique aux études d’évaluation de l’efficacité des bibliothèques. L’analyse de systèmes, dont les principes sont exposés, constitue l’approche la plus fréquemment retenue dans les études de ce genre en sciences de l’information. Suit la définition de la nature de la microévaluation qui fait appel à des indicateurs d’efficacité pour effectuer une auto-évaluation rigoureuse des résultats, de la qualité des produits et des services documentaires réalisés par une bibliothèque. Vient enfin une analyse critique des philosophies du « collège-bibliothèque » et des « media center », qui n’identifient pas la bibliothèque d’enseignement à un système documentaire.

Traitement des acquisitions et du catalogage par ordinateur (TACØ)
Authors: Boivin Richard , Fortin Michel , Jacob Michel 
Published: February 2019

TACØ, système modulaire de traitement des acquisitions et du catalogage par ordinateur, permettra à la bibliothèque de l’Université du Québec à Trois-Rivières, d’ici trois ans, de gérer automatiquement ses différents procédés de collecte, d’organisation et de contrôle de ses documents. Le premier module est opérationnel depuis août 1976 : il assume les opérations de catalogage et d’indexation, assurant ainsi une zone d’échange avec BADADUQ, système collectif de repérage de la documentation disponible dans les bibliothèques et centres de documentation de l’Université du Québec. Le deuxième module dont l’analyse fonctionnelle est terminée, sera développé au cours de l’année académique 1976/1977; il comprendra les opérations de collecte des documents et de gestion comptable. Suivra immédiatement une troisième phase de développement orientée vers le contrôle de la circulation et de l’utilisation des collections. L’expertise acquise au cours du développement et de l’implantation du premier module de ce projet multidisciplinaire a été significative et encourageante pour la poursuite du plan global.
Les idéologies des bibliothécaires canadiens-français (1951-1968)
Authors: Gagnon Gilbert 
Published: February 2019

À l’aide des Rapports des travaux des congrès de l’ACBLF de 1951 à 1968, l’auteur retrace l’évolution des idées qui ont guidé l’action des bibliothécaires canadiens-français et déterminé les changements de leur profession. Deux périodes sont à distinguer : la première (de 1951 à 1960) qui est dominée par l’humanisme chrétien et la seconde (de 1960 à 1968) qui est caractérisée par la montée de l’idéologie scientifique. La conclusion s’impose d’elle-même : la vision du monde, la praxis et le mode d’argumentation du bibliothécaire varient d’une période à l’autre parce qu’issus de conceptions différentes.
La motivation au travail : quelques considérations théoriques et pratiques
Authors: DuBois Pierre 
Published: February 2019

La motivation au travail prend de plus en plus d’importance avec l’émergeance de nouvelles valeurs sociales qui favorisent la liberté, l’expression et la diversité chez les employés. F. Herzberg a élaboré une théorie de la motivation selon laquelle une personne est motivée par deux besoins psychologiques distincts : besoin de protection contre les éléments dangereux de l’environnement et besoin de réalisation de soi. L’originalité de cette théorie est d’établir une distinction entre les facteurs de conditionnement (sécurité) et les facteurs de motivation (réalisation de soi) qui sont à l’origine de la gratification dans le travail. Des réponses sont apportées, à la lumière de cette théorie, à quelques questions courantes des cadres d’entreprise.
Services au public et services techniques : conflit ou complémentarité ?
Authors: Patry Hélène , Ranger Pâquerette 
Published: February 2019

Il existe un certain clivage entre le personnel des services au public et celui des services techniques. Ceci provoque de nombreuses difficultés au niveau des relations de travail influant sur la diffusion de l’information. Les auteurs cernent les principaux problèmes entre ces deux groupes : complexe d’infériorité de l’un envers l’autre groupe par rapport à la nature du travail effectué, instruments de repérage de l’information inadaptés aux besoins de l’usager, etc. Puis ils élaborent des éléments de solution à court, long et très long terme dont le principal sera sans conteste l’automatisation des services.
La bibliothèque publique et les Québécois
Authors: Castonguay André 
Published: February 2019

Après avoir défini la bibliothèque publique, l’auteur rappelle l’esprit dans lequel furent instaurées et maintenues trop longtemps au Québec les bibliothèques publiques. La révolution culturelle des années soixante a contribué à redéfinir la notion du « savoir » et, par conséquent, des institutions qui en demeurent le dépôt, les bibliothèques publiques.
Dans cet essai, l’auteur vise à discuter une philosophie de la bibliothèque publique appliquée à la réalité culturelle québécoise.
Psychological flexibility and attitudes toward evidence-based interventions by amyotrophic lateral sclerosis patients
Authors: Pearlman James R. , Thorsteinsson Einar B. 
Published: February 2019

Objective
Declining a percutaneous endoscopic gastrostomy (PEG) or non-invasive ventilation (NIV) by people with amyotrophic lateral sclerosis (ALS) is often contrary to advice provided by health-care-professionals guided by evidence-based principles. This study proposes relational frame theory (RFT) to offer a viable explanation of this phenomenon.

Design
A total of 35 people (14 female, 21 male) aged between 34 and 73 years, with ALS, participated in this cross-sectional research.

Main outcome measures
This research examined the predictive power and interaction effect of psychological flexibility (the fundamental construct of RFT) and psychological well-being on attitudes toward intervention options.

Results
Participants with high psychological flexibility reported lower depression, anxiety, and stress, and higher quality of life. In addition, psychological flexibility was predictive of a participant’s understanding and acceptance of a PEG as an intervention option. Psychological flexibility was not found to be a significant predictor of understanding and acceptance of NIV.

Conclusion
Although the criterion measure had not been piloted or validated outside of the current study and asks about expected rather than actual acceptance, findings suggest that applied RFT may be helpful for clients with ALS.
Employers’ Perceptions about the Employability of Technical, Vocational Education and Training Graduates in Uganda
Authors: Kintu Denis , Kitainge Kisilu. M. , Ferej Ahmed 
Published: February 2019

Aims: The study aimed at determining employers’ perceptions about the employability of Technical, Vocational Education and Training (TVET) graduates in Uganda. Determining employability skills from the employer’s perspective is crucial to develop these skills among the students while at the training institutions.
Study Design: Survey.
Place and Duration of Study: Sample: Employers of TVET graduates in Uganda. Between February 2018 to August 2018.
Methodology: The study adopted and modified a SCANS (Secretary's Commission on Achieving Necessary Skills) questionnaire. Sample: The study involved 50 respondents selected from different employing organizations.
Results: The findings indicated that most employers agreed that the graduates possessed the basic skills (average mean=3.91), ICT skills (average mean=3.87), and interpersonal skills required for work (average mean=3.61). However, there were negative perceptions regarding their decision making (mean= 2.39), reasoning (mean=2.96), self-esteem (mean=2.92), sociability’ (mean=2.90), integrity/honesty (mean= 2.60), money (mean=2.57), materials and facilities management (mean=2.67); understanding systems (mean=2.79), monitoring and correcting performance (mean=2.40), and improving systems (mean=2.24). Further, that most employers don’t participate in curriculum design (50%).
Conclusion: TVET institutions should endeavor to improve on the negatively perceived aspects to instill the necessary employability skills among the graduates to make them readily employable.
Risk Assessment of Specific Strains of Lactobacillus acidophilus Used as "Other Substances"

The Norwegian Scientific Committee for Food Safety (Vitenskapskomiteen for mattrygghet, VKM) has, at the request of the Norwegian Food Safety Authority (Mattilsynet; NFSA), assessed the risk of "other substances" in food supplements sold in Norway. These risk assessments will provide NFSA with the scientific basis for regulation of the addition of “other substances” to food supplements and other foods.
"Other substances" are described in the food supplement directive 2002/46/EC as substances other than vitamins or minerals that have a nutritional and/or physiological effect. It is added mainly to food supplements, but also to other foods. VKM has not in this series of risk assessments of "other substances" evaluated any claimed beneficial effects from these substances, only possible adverse effects.
The present report is a risk assessment of Lactobacillus acidophilus W37, Lactobacillus acidophilus DDS-1, Lactobacillus acidophilus La-5 and Lactobacillus acidophilus La-14 based on previous risk assessments and also publications retrieved from literature search.
The risk of the Lactobacillus strains listed above was assessed for the general population. However, in previous assessments of probiotics published by VKM, concerns have been identified for specific groups. Therefore, the risk was assessed for the age group with immature gastro-intestinal microbiota (age group 0-36 months), population with mature gastro-intestinal microbiota (>3 years) and vulnerable groups with mature gastro-intestinal tract. VKM has also assessed the risk of L. acidophilus W37, L. acidophilus DDS-1, L. acidophilus La-5 and L. acidophilus La-14 in food supplements and other foods independent of the dose and have assessed exposure in general terms.
VKM concludes that it is unlikely that L. acidophilus W37, L. acidophilus DDS-1, L. acidophilus La-5 and L. acidophilus La-14 would cause adverse health effects in the general healthy population with mature gastro-intestinal tract.
However, no data on long-term adverse effects on infants and young children were identified. As evidence is accruing that the early microbial composition of the neonatal gut is important for the development of the gut microbiota and the immune system of the growing child, it is not possible to exclude that a daily supply of a single particular bacterial strain over a prolonged period of time to an immature gastro-intestinal tract may have long-term, although still unknown, adverse effects on that development.

Published: February 2019

Aim: Organic wastes were composted and the effect of temperature changes on the bacterial and fungal succession patterns studied.
Study Design: The wastes which included cow dung (CD), pig waste (PW), poultry litter (PL) and source-separated municipal solid waste (MSW) and their combinations: PL+MSW, PW+MSW and CD+MSW were allowed to decompose for 70 days in a greenhouse.
Place and Duration of Study: This study was carried out between September 2017 and January 2018, in the greenhouse of the Agricultural Research Farm of Federal University of Technology, Owerri, Nigeria.
Methodology: The wastes were allowed to decompose for 70 days in a greenhouse using the modified windrow method of composting. Standard microbiological methods were used to monitor temperature changes in compost piles as well as changes in bacterial and fungal populations.
Results: Results revealed that changes in temperature affected microbial composition in the compost piles. The highest temperature recorded was 60oC for cow dung (CD) compost pile while at maturity the temperature in all the compost piles ranged between 27°C to 30°C. Different bacterial and fungal populations were isolated during the thermophilic and mesophilc phases of composting. Bacteria isolates included species of Staphylococcus, Proteus, Klebsiella, Salmonella, Alcaligenes, Serratia, Lactobacillus and Pseudomonas. Others included Enterobacter, Bacillus, Streptococcus, Corynebacterium and Micrococcus spp. Fungal species isolated included Candida, Saccharomyces, Rhizopus, Aspergillus, Mucor and Fusarium.
Conclusion: The presence of some plant growth promoting (PGP) bacteria at the end of composting qualifies organic waste composts as effective nutrient sources for crop production and can be considered as potential alternatives to chemical fertilizers.

Authors: Urabe Shigehiko , Terao Yoshiaki , Tominaga Shozo , Oji Makito , Fukusaki Makoto , Hara Tetsuya 
Published: February 2019

Aims: Introduction: Spinal fusion surgery is often associated with severe postoperative pain. This study aimed to determine whether intravenous acetaminophen produces equivalent analgesic effects to flurbiprofen under fentanyl patient-controlled analgesia (PCA) after one-level lumbar spinal fusion surgery.
Study Design: Rondomized controlled trial.
Place and Duration of Study: Department of Anesthesia, Nagasaki Rosai Hospital, Sasebo Japan, between October 2015 to March 2017.
Methodology: We studied 75 patients who underwent one-level lumbar spinal fusion surgery. Patients were randomly allocated to 1 of 3 groups: Group A (n = 25), which received 15 mg/kg acetaminophen intravenously every 6 hr. Group F (n = 25), which received 1 mg/kg flurbiprofen intravenously every 8 hr; and Group C (n = 25), which received saline every 6 hr as the control. Each drug was started from prior to skin closure to 24 hr after surgery. All patients received fentanyl at a fixed dose of 0.33 μg/kg/hr continuously after a bolus administration of 250 μg fentanyl. A bolus of 0.33 μg/kg of fentanyl was administered on demand by PCA (lockout interval 15 min). Postoperative pain was evaluated using a numerical rating scale (NRS) at 1, 2, 6, 12, 24 hr postoperatively and fentanyl consumption was recorded for 6 and 24 hr after surgery. The frequency of bolus fentanyl administration were also recorded.
Results: There were no significant differences in NRS scores among the 3 groups. Acetaminophen and flurbiprofen did not show opioid sparing-effects under fentanyl PCA. However, the frequency of fentanyl boluses were significantly less in group A than in group C.
Conclusions: Acetaminophen may produce equivalent analgesic effects to flurbiprofen after one-level lumbar spinal fusion surgery.
Model Reference Adaptive Control
Authors: Yucelen Tansel 
Published: February 2019

AbstractAdaptive control methods present effective system‐theoretical tools in order to achieve closed‐loop system stability and performance in the presence of exogenous disturbances and system uncertainties, where they are generally classified as either direct or indirect. A well‐known class of direct adaptive control methods is model reference adaptive control architectures. In particular, these architectures employ two major components – a reference model and a parameter adjustment mechanism. A desired closed‐loop dynamical system response is captured by the reference model for which its response is compared with the response of the uncertain dynamical system. The system error signal resulting from this comparison drives the parameter adjustment mechanism. This mechanism then adjusts the controller parameters in a real‐time (i.e., online) manner for driving the trajectories of the uncertain dynamical system to the trajectories of the reference model. This article discusses these components in a basic state feedback setting in order to provide an introduction to the model reference adaptive control design procedure. The article also makes connections to several other, relatively advanced model reference adaptive control methods for interested readers.

Multiband Filters
Authors: Fan Haijun 
Published: February 2019

AbstractIn this article, parallel multiplexing, in‐line, and parallel resonator topologies can be selected to realize a multiple band filter. The multiband filtering functions can be synthesized with four different theories: complex load, frequency transformation, strategic optimization, and direct iterative methods. Once the polynomials in reflect and transmission coefficients are obtained, the coupling matrix for realizing the multiband filter can be obtained directly. The multiband filters with selected topology can then be realized using planar, multilayer, coaxial, and waveguide structures. Furthermore, dual‐mode and multimode resonators can be introduced for size reduction.
Control of Power Converters inacanddcMicrogrids

Published: February 2019

Abstractac and dc microgrids (MGs) are small and localized power electronics intensive systems that are key enablers of the distributed generation (DG) paradigm. They will facilitate integration of distributed energy resources including renewable energy, microgeneration, and energy‐storage systems. On the other hand, owing to lack of natural inertia in power electronics converters and nonlinearities caused by their switching procedures, MGs are a challenging technology from a control point of view. In that sense, significant efforts have been taken over the past decade to understand, improve, and standardize the control structure of both ac and dc MGs. This article presents a review of several well‐known and also some recently proposed control algorithms for the realization of a stable and well‐behaved performance of such systems. Experimental results are provided to validate the performance of several selected methods. The article is concluded with the introduction of some emerging research topics and future MG development trends. They are mostly related to the design of intelligent energy management systems within the individual MG, as well as with the integration of multiple MGs into the future smart grid with the help of information and communication technologies (ICT).
