Contribuições do PIBID Diversidade da UFMG na formação de professores em curso de licenciatura
Authors: SILVEIRA Kátia Pedroso , NOGUEIRA Paulo Henrique de Queiroz
Published: December 2018

O artigo retrata possíveis contribuições para a formação de professores em cursos de licenciatura a partir da experiência do PIBID Diversidade na Universidade Federal de Minas Gerais junto a dois cursos específicos: Licenciatura em Educação do Campo/LECAMPO e o Curso de Formação Intercultural para Educadores Indígenas/FIEI. Esses dois cursos, criados na esteira da mobilização dos povos do campo e indígenas pelo direito à educação, possuem características que os diferenciam das demais licenciaturas ao agregar percursos formativos próprios e singulares para a formação inicial de docentes. Levando-se em consideração as marcas indenitárias dessas populações num processo espiralado em que o direito à educação se encarna em sujeitos corpóreos com suas tradições, oralidade, religiosidade e pertencimentos étnico-racial, territorial e linguístico; os cursos, em um momento inicial, e o PIBID, em seus desdobramentos, postulam ser possível formar professores para a Educação Básica reconfigurando as proposições curriculares e a organização de seus tempo e espaços ao se permitir ultrapassar velhos dilemas interpostos na formação docente. Educação Indígena. Educação do Campo. Formação Inicial de Professores. Contributions of the PIBID Diversidade from the UFMG in teachers training on degree course ABSTRACTThe article portrays contributions for teacher training in undergraduate courses from the experience of the PIBID Diversidade (Institutional Scholarship Initiative Program for Diversity) at the Federal University of Minas Gerais together with two specific courses: Countrified Education Degree/LECAMPO and the Intercultural Training Course for Indigenous Educators/FIEI. These two courses, created by the mobilization of rural and indigenous peoples for the right to education, have characteristics that differentiate them from others degree courses by adding some particular and unique formative pathways to the initial teachers training. Taking into account the indenitational marks of these populations in a spiral process in which the right to education is embodied in corporeal individuals with their traditions, orality, religiosity and ethnic-racial, territorial and linguistic belongings; the courses, in an initial moment, and the PIBID, in their unfolding, postulate that it is possible to train teachers for Basic Education by reconfiguring the curricular propositions and the organization of their time and spaces by allowing to overcome old dilemmas interposed in the teacher formation. Indigenous Education, Countrified Education, Initial Teachers Training.
Rádio Comunitária e povos indígenas: entraves e potencialidades para pluralidade de vozes
Authors: MESQUITA Giovana Borges
Published: December 2018

O artigo busca analisar os principais entraves para a instalação e funcionamento de uma rádio comunitária numa área indígena situada em Pernambuco, estado com a quarta maior população indígena do Brasil, composta por mais de 47 mil pessoas, que habitam a região Agreste e o Sertão. Ao mesmo tempo, o trabalho propõe uma reflexão sobre como as comunidades indígenas, na maioria das vezes criminalizadas pela mídia hegemônica, podem tentar caminhos para ter acesso a comunicação, como um direito humano, assumindo a rádio comunitária como espaço para o exercício da cidadania. O trabalho é um relato da experiência da “gestação”, ao longo do último ano (2017-2018) do Programa Institucional de Bolsas de Iniciação à Docência para a Diversidade (Pibid Diversidade), de uma rádio comunitária na web, que como destaca Peruzzo (2010), é um espaço propício ao fornecimento de informações e de discussão dos assuntos de interesse local, além de funcionar difundindo a produção cultural dos grupos onde está inserida e em seus entornos. Rádio Comunitária.

التراخيص النفطية ودورها في مستقبل الصناعة النفطية بالعراق
Authors: الراوي احمد عمر
Published: December 2018

مرت الصناعة النفطية في العراق بحقب مختلفة ، بدأت بهيمنة الشركات الغربية على استثمار النفط العراقي في عشرينيات القرن الماضي،مرورا بعملية تأميم حصص تلك الشركات بداية السبعينيات، وانتهاءا بالسياسات الجديدة التي اعتمدتها الحكومة العراقية مؤخرا، التي تمثلت بالتعاقد مع من الشركات العالمية لتطوير الصناعة النفطية .بسبب ما الت اليه الصناعة النفطية من تراجع في قدراتها الفنية والمادية نتيجة ظروف الحروب والحصار المفروض على العراق قبل عام 2003.

  وقد طرحت الحكومة العراقية تراخيص للتعاقد في تطوير الحقول النفطية المنتجة.من خلال جولتي منافسة شارك فيها عدد من الشركات والتكتلات العالمية.للدخول بعقود طويلة الامد لتطوير الحقول النفطية مقابل اجور محددة لقاء كل برميل منتج.وقد تم التعاقد مع عدد من الشركات التي فازت بعقود تطوير الحقول النفطية (مجنون ، الحلفية ،غرب القرنة ،الغراف،بدرة) ويتوقع ان يرفع تنفيذ هذه العقود الطاقة الانتاجية من معدلاتها الحالية التي تقدر 2مليون برميل/يوم الى نحو12 مليون برميل /يوم من النفط الخام مطلع العقد الثاني من القرن الحالي .

وقد اثارت تلك العقود جدلا واسعا بين مؤيد ومعارض لها، بحجة ان العقود المشار اليها ينقصها السند القانوني وانها عودة الى سيطرة الشركا ت العالمية على الثروة النفطية العراقية.

ان خوارزمية نظام النمل (A S A)  من أوائل إصدارات خوارزميات مستعمرة النمل المستوحاة من سلوك افراد النمل الطبيعي في المستعمرة الواحدة في البحث عن الطعام والتي تعتبر نموذج من نماذج ذكاء السرب (S I) والذي ينتمي الى حقل الذكاء الاصطناعي (A I) ، تُستخدم هذه الخوارزمية لايجاد الحلول المثلى او التي تقترب من الامثلية لمسائل الامثلية التوافقية (C O P) والتي يصعب إيجاد الحلول لها باستخدم الطرائق التقليدية المعروفة مثل البرمجة الخطية والبرمجة غير الخطية وغيرها .

تم تطبيق وتوظيف هذه الخوارزمية في مجال إدارة الموارد المائية وذلك على سد وخزان حديثة والذي يعد من اهم السدود في العراق ، لغرض إيجاد نظام ذو كفاءة عالية لادارة السد وذلك بتحديد حجوم الخزن المثلى الشهرية للمياه داخل السد وحجوم التصاريف المثلى الشهرية للمياه الى خارج السد . وقد كانت مدة الدراسة خمسة سنوات مائية متألفة من ستين شهرا (60) ابتداءاً من( 1/تشرين الأول/2007) ولغاية( 30/أيلول/2012 ) وكانت هذه البيانات سلاسل زمنية لحجوم الطلب الشهرية على المياه ، وحجوم التدفق الشهرية على المياه وحجوم التبخر الشهرية على المياه وحجوم الخزن الشهرية للمياه  . وقد تم اقتراح نظام لادارة السد يضمن حجوم خزن شهرية داخل الخزان ضمن الحدود التصميمية وكذلك يضمن عدم الوصول الى عجز في المياه والذي يؤدي الى استخدام الوحدات التوربينية لتشغيل السد وهذا التشغيل الأمثل يؤدي الى الترشيد في استهلاك الطاقة الكهربائية وإمكانية توليد الطاقة الكهرومائية بشكل اكفأ من الوضع الحالي للسد. وقد تم عمل برنامج لتطبيق هذه الخوارزمية باستخدام الحزمة البرامجية (Matlab).
الاحتيال في ظل القيمة العادلة "دراسة استطلاعية"
Authors: فليح حكيم حمود
Published: December 2018

هدف البحث إلى التعرف على مفهوم القيمة العادلة ومناهج قياسها، وإلقاء الضوء على مفهوم الاحتيال وأشكاله ودوافعه، فضلاً عن التعرف على كيفية الاحتيال في ظل منهج القيمة العادلة.

وقد تم استخدام برنامج الحزمة الإحصائية SSPS في حساب متغيرات البحث، وتمثلت عينة البحث بمجموعة من أساتذة الجامعات ومراقبي الحسابات العاملين في ديوان الرقابة المالي الاتحادي.

وقد توصل الباحث إلى استنتاجات أهمها إن عدم وجود دليل قاطع حول نية الإدارة في تبني استعمال القيمة العادلة، يثير شكوك عدة حول مصداقية الكشوفات المعدة في ضوء القيمة العادلة.

كما إن استعمال القيمة العادلة للشركات المدرجة في سوق العراق قد يؤدي الى تأخير إصدار كشوفات مالية في الوقت الملائم مما يفقد الفائدة من تلك الكشوفات، إذ أن الشركات مع تطبيق الكلفة التاريخية فإنها تتأخر في أعداد الكشوفات المالية وإصدارها.

كما أوصى الباحث بمجموعة من التوصيات أهمها :

ينبغي عدم التضحية بالموضوعية والتوقيت الملائم مقابل معلومات قد لا تكون ملائمة لمستخدمي الكشوفات المالية.

ضرورة تبني مدخل معياري في حال تبني أي معيار يلزم الشركات بتطبيق القيمة العادلة في القياس المحاسبي للكشوفات المالية للحد من المرونة وإمكانية التلاعب في البنود المالية

Comparative Efficacy of Nebulized 3% Hypertonic Saline versus 0.9% Normal Saline in Children with Acute Bronchiolitis
Authors: Islam Khandaker Tarequl , Mollah Abid Hossan , Matin Abdul , Begum Mahmuda
Published: December 2018

Background: Acute bronchiolitis is leading cause of hospitalization in infants below 2 years of age. Bronchiolitis being a viral disease, there is no effective treatment. 3% nebulized hypertonic saline and 0.9% nebulized normal saline are often used, although there is disagreement over their efficacy. The aim of this study was to evaluate the efficacy of 3% hypertonic saline in children with acute bronchiolitis in reducing clinical severity and length of hospital stay.

Methodology: A randomized control trial carried out in the Department of Pediatrics, Dhaka Medical College Hospital from January 2013 to December 2013.Ninty children from 1 month to 2 years of age hospitalized with clinical bronchiolitis were randomized to receive 3% nebulized hypertonic saline(Group-I) or 0.9% nebulized normal saline (Group-II). Nebulization was done 8 hourly until discharge. Outcome variable were clinical severity score, duration of oxygen therapy and length of hospital stay.

Results: Baseline clinical severity score and O2 saturation were in group-I 9.0±1.0 and 94.9±1.7 and in group- II 9.3±1.8 and 94.6±2.6 respectively (p>0.05). At 72 hours, the mean severity score for the group-I was 1.64±0.99 and that for the group-II was 3.0 ± 1.48 (95% CI -2.17 to - 0.53, p=0.002). The cases of group-I required a shorter duration of oxygen therapy compared to those of group-II (15.0±6.0 hours vs 26.4±5.37 hours, 95% CI -20.35 to -2.44, p<0.05). Forty two (93.3%) of the group-I children recovered by the end of72 hours and discharged whereas 26 (57.8%) of the group-II children recovered during the same period (p<0.05). Length of hospital stay was shorter in group-I compared to group-II (58.1±22.0 hours vs 74.7±27.2 hours, 95% CI -26.89 to- 6.17, p=0.002). None of the cases encountered any side-effects.

Conclusion: Nebulization with 3% hypertonic saline significantly reduced clinical severity, length of hospital stay and duration of oxygen therapy in case of acute bronchiolitis in comparison to 0.9% normal saline and was safe.

Experiences of Tourists Suffering from Food Intolerances
Authors: Schiefert Viktoria-Maria , Matteucci Xavier
Published: December 2018

The number of people who are affected by a food intolerance has risen dramatically over recent years. Although food plays a central role in tourism experiences, little is known about how food-intolerant people experience eating out during their holiday (away from home). To fill this
knowledge gap, and following a constructivist grounded theory strategy, nine in-depth interviews with food-intolerant tourists were conducted. The textual data analysis revealed four main themes, which underpin the experiences of tourists with food intolerances: mistrust of food labeling and
restaurant personnel, uncertainty, the feeling of being a burden to others, and the perceived lack of empathy in food-intolerant customers. Each one of these four themes are a source of worry and stress to people with food intolerances. Implications for practice are discussed.

Published: December 2018

We present results derived from the analysis of spectropolarimetric measurements of active region AR12546, which represents one of the largest sunspots to have emerged onto the solar surface over the last 20 years. The region was observed with full-Stokes scans of the Fe i 617.3 nm and Ca ii 854.2 nm lines with the Interferometric BIdimensional Spectrometer instrument at the Dunn Solar Telescope over an uncommon, extremely long time interval exceeding three hours. Clear circular polarization (CP) oscillations localized at the umbra–penumbra boundary of the observed region were detected. Furthermore, the multi-height data allowed us to detect the downward propagation of both CP and intensity disturbances at 2.5–3 mHz, which was identified by a phase delay between these two quantities. These results are interpreted as a propagating magnetohydrodynamic surface mode in the observed sunspot.
The Influence of the Metal Mass Fraction Z, Age, and Mixing-length Parameter on the RGB Bump Magnitude for the M4 Cluster

Published: December 2018

We identify the location of the RGB bump of M4 (NGC 6121) using the available photometric data, and measure V
RGBB (∼13.57 ± 0.04 mag). According to the observed [Fe/H], we compute theoretical isochrones with the scaled-solar composition in the MESA model and alpha-enhanced composition in the BaSTI model, respectively. Using a color–magnitude diagram, we compare these isochrones with the observed data to obtain the magnitude difference δV
bump between the predicted and the observed bump magnitude. Based on the best fit of the MESA model with [Fe/H] = −1.05, [α/Fe] = 0, α
MLT = 2.0, and t = 13.3 Gyr, the bump magnitude difference δV
bump is about 0.46 mag. Based on the best fit of the BaSTI model with α
MLT = 2.2 ∼ 2.4, [Fe/H] = −1.05, [α/Fe] = 0.4, and t = 12.5 Gyr, the bump magnitude difference δV
bump is about 0.2 mag. To try and explain the bump magnitude differences, the metal mass fraction Z is enhanced as 0.0037, 0.00591, 0.0076, and 0.0085. Accordingly,

, and

by the MESA model are 0, −0.01, and 0 mag, respectively. Increasing the assumed metallicity can decrease the discrepancy between the predicted and observed bump magnitudes. However, a metallicity increase large enough to resolve the offset, roughly ∼0.60 dex for the MESA models, is ruled out by the spectroscopic data.

We present 13 seasons of R-band photometry of the quadruply lensed quasar WFI 2033–4723 from the 1.3 m SMARTS telescope at CTIO and the 1.2 m Euler Swiss Telescope at La Silla, in which we detect microlensing variability of ∼0.2 mag on a timescale of ∼6 years. Using a Bayesian Monte Carlo technique, we analyze the microlensing signal to obtain a measurement of the size of this system’s accretion disk of

at λ
rest = 2481 Å, assuming a 60° inclination angle. We confirm previous measurements of the BC and AB time delays, and we obtain a tentative measurement of the delay between the closely spaced A1 and A2 images of

days. We conclude with an update to the Quasar Accretion Disk Size–Black Hole Mass Relation, in which we confirm that the accretion disk size predictions from simple thin disk theory are too small.
Pollination and pollen germination in common juniper (Juniperus communis: Cupressaceae)
Authors: Surso Mikhail
Published: December 2018

Pollination and fertilization are the most important and responsible stages in sexual reproduction of coniferous plants. The period of high concentrations of juniper pollen in overhead during pollination period is no more than 4–6 hours and within one calendar day. This dependence remains invariable from year to year, and does not depend neither from weather conditions, nor the peculiarities of the place where juniper grows. Influence of external agents on dynamics of exudation of a juniper pollination droplet is studied. The duration of exudation and volume of secretory liquid exuded by tissues of ovules during the period of prescription in the juniper depend from presence of external agents on a surface of pollination droplet, their sizes and physical and chemical properties. The pollination droplet chemical compound is studied. In sugars composition of juniper pollination droplet there are only two monosaccharides: glucose and galactose. the amino acids composition is prevailed by arginine, aspartic and glutamic acids. The results of the studies confirm complex chemical composition and multifunctionality of juniper pollination droplet. The pollination mechanism of juniper is effective and selective. The morphological structure of pollen grains of juniper predetermines the processes of pollen germination at early stages. The hydrophilic capsule, formed pollen hydration, promotes to exine rupture and shedding. This capsule remains until the fertilization. The distal tip of pollen tube remains in itduring all time of its growth. In culture in vitro development of pollen tubes of juniper proceeds non-uniformly. At definition of juniper pollen viability it is necessary to consider a stage of pollen tubes development.

Georeferencing is the process of aligning a text description of a geographic location with a spatial location based on a geographic coordinate system. Training aids are commonly created around the georeferencing process to disseminate community standards and ideas, guide accurate georeferencing, inform users about new tools, and help users evaluate existing geospatial data. The Georeferencing for Research Use (GRU) workshop was implemented as a training aid that focused on the creation and research use of geospatial coordinates, and included both data researchers and data providers, to facilitate communication between the groups. The workshop included 23 participants with a wide background of expertise ranging from students (undergraduate and graduate), professors, researchers and educators, scientific data managers, natural history collections personnel, and spatial analyst specialists. The conversations and survey results from this workshop demonstrate that it is important to provide opportunities for biocollections data providers to interact directly with the researchers using the data they produce and vice versa.

Authors: Gudyrev Oleg S. , Andronova Tatyana M. , Nesterova Evgeniya I.
Published: December 2018

Introduction: The drug Licopid® (GMDP, glucosaminylmuramyldipeptide) is intended for complex therapy of conditions accompanied by secondary immunodeficiencies. This drug belongs to the group of microbial immunomodulators of bacterial origin. The transparent mechanism of action of the active substance GMDP allows putting the drug Licopid® into the category of promising immunotherapy drugs that are in demand in the complex therapy of many diseases resistant to traditional treatment. The objective of this study was to investigate the carcinogenicity of GMDP (Licopid®) in chronic animal experiments.

Materials and Methods: The study of the carcinogenic effects of GMDP was carried out in mice hybrids F1 CBAxC57BL6 and Wistar rats of both sexes with intragastric administration five days a week (Mon-Tue-Wed-Thu-Fri) for 18 months at doses of 0.186 mg/kg, 1.86 mg/kg and 6.13 mg/kg to mice and for 21 months at doses of 0.086 mg/kg, 0.86 mg/kg and 2.83 mg/kg to rats.

Results and Discussion: The results of the clinical observation of the experimental animals in the course of the study demonstrated the absence of differences between mice and rats of the experimental and control groups.

Conclusion: Intragastric administration of GMDP to male and female mice for 18 months and rats for 21 months at the studied doses did not lead to tumor formation in the experimental animals.

Published: December 2018

The relationship between the generaCleopomiarusandMiarusof Mecinini (Curculionidae, Curculioninae) was tested on the basis of morphological characters from the immature stages. The mature larvae of fiveCleopomiarusspecies (C.distinctus(Boheman, 1845),C.graminis(Gyllenhal, 1813),C.longirostris(Gyllenhal, 1838),C.medius(Desbrochers des Loges, 1893), andC.meridionalis(H. Brisout de Barneville, 1863)), threeMiarusspecies (M.abnormisSolari, 1947,M.ajugae(Herbst, 1795), andM.campanulae(Linnaeus, 1767)), and the pupae of fourCleopomiarusspecies (C.distinctus,C.graminis,C.longirostris, andC.medius) and twoMiarusspecies (M.abnormisandM.ajugae) are described in detail for the first time. To confirm the taxonomic identification of some larvae, DNA COI barcode was obtained and compared with those of adults. The immature stages of the species herein studied were compared with those known from other genera in tribe Mecinini. It is suggested thatMiarusandCleopomiarusmay be monophyletic based on several shared distinctive characters. Larvae ofMiarushave a characteristic maxillary mala with six finger-likedmsof two sizes (one or twodmsvery long and the rest of medium length), this feature being apparently unique among weevils. Other genus-specific character states are observed in the pupae, such as the length of setae on the head, rostrum and pronotum, including the number ofrson the rostrum,dson pronotum, and finally the shape of the urogomphi. A key to the described larvae and pupae were respectively presented. New biological and distributional data on some species are reported.
A taxonomic revision and molecular phylogeny of the eastern Palearctic species of the genera Schizomyia Kieffer and Asteralobia Kovalev (Diptera, Cecidomyiidae, Asphondyliini), with descriptions of five new species of Schizomyia from Japan
Authors: Elsayed Ayman Khamis , Yukawa Junichi , Tokuda Makoto
Published: December 2018

The genusAsteralobia(Diptera, Cecidomyiidae, Asphondyliini, Schizomyiina) was erected by Kovalev (1964) based on the presence of constrictions on the cylindrical male flagellomeres. In the present study, we examine the morphological features ofAsteralobiaandSchizomyiaand found that the male flagellomeres are constricted also inSchizomyiagaliorum, the type species ofSchizomyia. Because no further characters clearly separatingAsteralobiafromSchizomyiawere observed, we synonymizeAsteralobiaunderSchizomyia. Molecular phylogenetic analysis strongly supports our taxonomic treatment. We describe five new species ofSchizomyiafrom Japan,S.achyranthesaeElsayed & Tokuda,sp. n.,S.diplocyclosaeElsayed & Tokuda,sp. n.,S.castanopsisaeElsayed & Tokuda,sp. n.,S.usubaiElsayed & Tokuda,sp. n., andS.paederiaeElsayed & Tokuda,sp. n., and redescribe three species,S.galiorumKieffer,S.patriniaeShinji, andS.asterisKovalev. A taxonomic key to the JapaneseSchizomyiaspecies is provided.

Workplace flourishing: Measurement, antecedents and outcomes
Authors: Redelinghuys Kleinjan , Rothmann Sebastiaan , Botha Elrie
Published: December 2018

Orientation: The continuous growth of employee attrition, especially within the highly skilled talent pool, is becoming increasingly problematic. Therefore, one should continually explore the different factors that impact employee retention and performance. This casts the attention to the person–environment fit and workplace flourishing (WF).Research purpose: This study explored relationships among person–environment fit, WF, intention to leave (ITL), in-role performance and organisational citizenship behaviour.Motivation for the study: Disease-driven research heavily outweighs health promotion research. Therefore, more research is needed regarding positive employee behaviours such as strengths, optimal functioning and flourishing.Research approach/design and method: A cross-sectional survey design was used with 258 secondary school teachers from two Gauteng districts. The Perceived Fit, Flourishing-at-Work, Turnover Intention, In-Role Behaviour and Organisational Citizenship Behaviour scales were administered. Structural equation modelling and mediational analyses were performed.Main findings: Results confirmed WF’s three-factor structure. Person–environment fit positively associated with WF. Workplace flourishing negatively related to ITL, while positively relating to in-role performance and organisational citizenship behaviour. Person–environment fit indirectly affected in-role performance and organisational citizenship behaviour via WF.Practical/managerial implications: Organisations should continually modify their strategic frameworks to maintain a healthy balance between individual and environmental characteristics. This will lay the foundation for a favourable work environment. When such an environment is institutionalised, talent retention and performance should follow.Contribution/value-add: The study results should provide new insight into the relationship between the person–environment fit and WF, as well as the effect it may have on ITL and performance.
Simplicial (Co)-homology of
Authors: Farhat Yasser , Gourdeau Frédéric
Published: December 2018

We consider the unital Banach algebra$\ell ^{1}(\mathbb{Z}_{+})$and prove directly, without using cyclic cohomology, that the simplicial cohomology groups${\mathcal{H}}^{n}(\ell ^{1}(\mathbb{Z}_{+}),\ell ^{1}(\mathbb{Z}_{+})^{\ast })$vanish for all$n\geqslant 2$. This proceeds via the introduction of an explicit bounded linear operator which produces a contracting homotopy for$n\geqslant 2$. This construction is generalised to unital Banach algebras$\ell ^{1}({\mathcal{S}})$, where${\mathcal{S}}={\mathcal{G}}\cap \mathbb{R}_{+}$and${\mathcal{G}}$is a subgroup of $\mathbb{R}_{+}$.
Diameter, Decomposability, and Minkowski Sums of Polytopes
Authors: Deza Antoine , Pournin Lionel
Published: December 2018

We investigate how the Minkowski sum of two polytopes affects their graph and, in particular, their diameter. We show that the diameter of the Minkowski sum is bounded below by the diameter of each summand and above by, roughly, the product between the diameter of one summand and the number of vertices of the other. We also prove that both bounds are sharp. In addition, we obtain a result on polytope decomposability. More precisely, given two polytopes $P$ and $Q$, we show that $P$ can be written as a Minkowski sum with a summand homothetic to $Q$ if and only if $P$ has the same number of vertices as its Minkowski sum with $Q$.
Calabi–Yau deformations and negative cyclic homology
Authors: de Thanhoffer de Völcsey Louis , Van den Bergh Michel
Published: December 2018

In this paper we relate the deformation theory of Ginzburg Calabi–Yau algebras to negative cyclic homology. We do this by exhibiting a DG-Lie algebra that controls this deformation theory and whose homology is negative cyclic homology. We show that the bracket induced on negative cyclic homology coincides with Menichi's string topology bracket. We show in addition that the obstructions against deforming Calabi–Yau algebras are annihilated by the map to periodic cyclic homology. In the commutative we show that our DG-Lie algebra is homotopy equivalent to

(T^{\mathrm poly}[[u]],-u\:\mathrm {div})

A unified approach of blow-up phenomena for two-dimensional singular Liouville systems
Authors: Battaglia Luca , Pistoia Angela
Published: December 2018

We consider generic

2\times 2

singular Liouville systems

(\star)\quad \left\{ \begin{array}{ll} -\Delta u_1=2\lambda_1 \,e^{u_1}-a\lambda_2 \,e^{u_2}-2\pi (\alpha_1-2)\delta_0& \text{in }\Omega, \\ -\Delta u_2=2\lambda_2 \,e^{u_2}-b\lambda_1 \,e^{u_1}-2\pi (\alpha_2-2)\delta_0&\text{in }\Omega,\\ u_1=u_2=0&\text{on }\partial\Omega,\end{array}\right.

where

\Omega \ni 0

is a smooth bounded domain in

\mathbb R^2

possibly having some symmetry with respect to the origin,

\delta_0

is the Dirac mass at

0,

\lambda_1,\lambda_2

are small positive parameters and

a,b,\alpha_1,\alpha_2 > 0

.

We construct a family of solutions to

(\star)

which blow up at the origin as

\lambda_1 \to 0

and

\lambda_2 \to 0

and whose local mass at the origin is a given quantity depending on

a,b,\alpha_1,\alpha_2

.

In particular, if

ab < 4

we get finitely many possible blow-up values of the local mass, whereas if

ab \ge 4

we get infinitely many. The blow-up values are produced using an explicit formula which involves Chebyshev polynomials.
Professionalization of the Field of Adult Education in Former Yugoslavia
Authors: Ovesni Kristinka
Published: December 2018

In this paper we discuss the professionalisation of adult education and learning in the territory of former Yugoslavia. The rationale behind the paper is based on the presumption that the process of professionalisation represents a reflection of social conditions, tradition, culture, development of higher education institutions, the scientific/knowledge base for a certain field on the main elements of the profession. Our aim is to critically discuss professionalisation in the field of adult education and learning with a threefold focus (on the profession, representing the sociological dimension, on professionalism, representing the philosophical/ethical dimension, and on professionalisation, representing the andragogical dimension). The findings indicate that in the territory of former Yugoslavia significant but insufficient progress has been made when it comes to shaping the field of professional practice and in the professional preparation of andragogues/adult educators at universities, including improvement in continuing professional development. On the other hand, when it comes to establishing professional associations, licensing, and the development of professional code(s) of ethics, the process of professionalisation has been very moderate and slow.
Izobraževanje odraslih v Sloveniji pred tranzicijo in po njej
Authors: Jelenc Zoran
Published: December 2018

Po letu 1991, ko je Slovenija postala samostojna, je država z več sistemskimi ukrepi podprla razvoj izobraževanja odraslih: v državnem proračunu odobrena posebna sredstva za izobraževanje odraslih; ustanovljen sektor za izobraževanje odraslih na ministrstvu za šolstvo; sprejet poseben zakon o izobraževanju odraslih; ustanovljena posebna strokovna ustanova za razvoj in pospeševanje razvoja izobraževanja odraslih; zasnovan nacionalni program za izobraževanje odraslih; oblikovan program visokošolskega študija andragogike; začele delovati številne zasebne organizacije za izobraževanje odraslih; nastala nova združenja za izobraževanje odraslih; začela izhajati strokovna in znanstvena revija za izobraževanje odraslih; stekli številni razvojni in raziskovalni projekti, namenjeni razvijanju in pospeševanju kulture učenja. Sprejeta je Strategija vseživljenjskosti učenja v Sloveniji. Kljub temu izobraževanje odraslih v Sloveniji sistemsko še ni ustrezno urejeno; ostaja na ravni, na kateri smo bili pred tremi ali štirimi desetletji.
Needs Assessments for School-based Agricultural Education Teachers: A Review of Literature
Authors: DiBenedetto Catherine A. , Willis Victoria C. , Barrick R. Kirby
Published: December 2018

School-based agricultural education (SBAE) programs have become more diverse with the ever changing and growing agriculture industry. Agricultural education teachers are challenged with expanding their knowledge and competencies to effectively teach and design successful SBAE programs. Needs assessments aid in providing guidance for professional development to better equip teachers with adequate knowledge, experiences, resources and materials. To better understand how agricultural education teacher’s needs have changed or remained the same, this synthesis provided insight into teacher needs assessments from 1983 to 2015. While some competencies revealed inconsistent results, several competencies produced overwhelmingly cohesive results. Findings indicated Computer Technology, Program Administration, Public Relations, FFA/Program Management, Managing Student Behavior, and Development and Supervision of SAE projects as consistent needs of agricultural education teachers. Less emphasis was needed in professional development in technical skills related to the AFNR career pathways. A variation of needs between experienced and beginning teachers has existed. Recommendations included addressing emerging needs in 21st century competence and working with special needs. To emphasize content focus, development of a consistent instrument to assist teacher educators and national organizations with designing professional development opportunities to meet the current needs of agricultural education teachers in all stages of their careers was recommended.
Identifying Extension Agent Needs Associated with Communicating about Policies and Regulations
Authors: Rumble Joy N. , Lamm Alexa J. , Gay  , Keegan D.
Published: December 2018

The Cooperative Extension Service has performed the role of educator and change agent for more than a century. Changes occurring during this period caused Extension to extend its influence beyond the farm and traditional roles. Today, Extension faces controversial public issues and unparalleled levels of policy and regulation impacting agriculture and natural resources. As the needs of our changing society evolve, regulation increases, and response to public opinion becomes more complex. Extension must expand its role in providing education related to public issues and acting as facilitators and change agents to ensure viable actions are taken. This study was conducted to determine the level of preparedness of Florida Extension agents in dealing with policies and regulations. An emailed survey of all Florida Extension agents utilized questions regarding frequency of addressing policies with their clientele and their knowledge of said policies. Results indicated a low frequency of agents of all types addressing most policies with their clientele and a need for increased knowledge about the policies. In particular, there is an opportunity for all agent types to improve interactions with clientele on the topic of Immigration Reform as well as knowledge of related policies.
Student Perceptions of Soft Skills & Career Decision Self-Efficacy through Participation in SAE
Authors: Haddad Becky , Marx Adam A.
Published: December 2018

This study sought to assess student perceptions of soft skills and career decision self-efficacy attained through participation in different types of Supervised Agriculture Experience programs within School Based Agricultural Education. There was no significant difference found in career decision self-efficacy or perceived soft skill attainment between those who participated in SAE and those who did not. This study identified a positive significant impact for career decision selfefficacy and perceived soft skill attainment between those who had placement and exploratory SAEs with the exception of the problem-solving construct. Findings suggest that students participating in programs that require greater investment of student time, skill, capital, and initiative develop greater perceived skill attainment and efficacy through the SAE program.
A Model for Understanding Decision-Making Related to Agriculture and Natural Resource Science and Technology
Authors: Ruth Taylor K. , Rumble Joy N. , Lamm Alexa J. , Ellis Jason D.
Published: December 2018

Agricultural educators, leaders, communicators, and extension professionals are faced with the increasingly difficult task of sharing science-based information to a public that is exposed to an array of media options, which are not always factual. Additionally, issues related to agriculture and natural resources (ANR) have become increasingly complex, and people can elect to only read information or communication that supports their pre-existing views on a topic. The complexity of disseminating information in today’s society has led to the proposal of a new theoretical model: The Decision-Making Model for ANR Science and Technology. This is a multi-facetted model utilizing the theoretical foundations from the Theory of Diffusion of Innovations, Theory of the Spiral of Silence, and the Elaboration Likelihood Model. In a world of echo chambers, this theory has the potential to break the cycle of decisions made with incomplete information and equip practitioners with the foundation needed to efficiently and effectively disseminate information through educational practice and informed communication efforts. An informed and aware public could make decisions about ANR science and technology with a more complete understanding of the issue, which would solve some of the wicked problems facing society today.
