Evidencias de decoupling en la sostenibilidad empresarial: un caso de estudio en el sector minero colombiano
Authors: Contreras-Pacheco Orlando E.
Published: October 2018

El fenómeno conocido como decoupling implica la desconexión entre el discurso y la acción organizacional; la incoherencia entre el decir y el hacer. El presente trabajo pretende ilustrar el decoupling asociado con la sostenibilidad empresarial mediante el uso de un caso de estudio particular. Para ello, se hace referencia a un incidente ambiental producido por una empresa multinacional perteneciente al sector de la minería del carbón a gran escala en Colombia. Además de resaltar la relevancia teórica de un concepto poco aplicado en el contexto de los países en vías de desarrollo, este estudio contribuye a la identificación del decoupling como fenómeno que permite comprender situaciones de disociación entre la política y las acciones en el ámbito de la empresa. En este sentido, el estudio de caso también permite comprender la caracterización del decoupling como práctica organizacional controvertida, identificando escenarios de aplicación con diferentes niveles de premeditación. Adicionalmente, desde el punto de vista práctico, y dado su enfoque normativo, el presente estudio resalta el decoupling como un comportamiento contraproducente para los objetivos de sostenibilidad de las empresas y de la sociedad entera.

Authors: Brusca Isabel , Olmo Jorge
Published: October 2018

El principio de sostenibilidad de deuda comercial establece un nuevo mecanismo de disciplina presupuestaria. Ante este contexto, el objetivo de este trabajo es analizar qué variables caracterizan mejor la liquidez de los municipios españoles. El Plan de Pago a Proveedores y el periodo medio de pago de los ayuntamientos son la referencia principal. Mediante un análisis discriminante y una regresión lineal, se evidencia que la ejecución del ahorro bruto, el periodo de cobro y los gastos corrientes están relacionados con la deuda comercial. Esta investigación contribuye en el estudio de las variables explicativas de la situación financiera a corto plazo.

Analysis of the Expression of Empowering Education under Conditions of Educational Inclusion
Authors: Galkienė Alvyra
Published: October 2018

In the research, the empowerment strategy application efficiency is analysed in the context of the construct of inclusive education, taking into account that the application of an empowerment strategy in the education process often determines the nature of interpersonal interaction as well. The research question raised: in what manner does the application of empowerment strategy encourage inclusive education processes?

The research was carried out by means of qualitative case study strategy. The object of analysis is the socio-educational experience of one class teacher. The data was collected via diary method. In her diary, the teacher reflects on her experiences in the following fields: education design, co-operation experiences, response to pupils’ needs, education process and environment, and curriculum.

It was revealed that various activities of pupil empowerment in the education process (setting rules, autonomous formulation of goals, progressive problem solving, information sharing) serve as a basis for the realization of inclusive education and are directly linked to various dimensions of the construct of the given education system. The activation process of inclusive education values benefits from clearly defining the limits to interpersonal actions through systematic reflection on community situations, discussion on pupils’ creative activities, and involving pupils in solving problematic organizational issues within the community. Enabling pupils to continuously participate in solving matters of the learning community allows to avoid the indoctrination of values and creates conditions to internalize the values of community spirit and respect through the recognition of differences between community members as a natural phenomenon.

Research results show that the construct of empowering education provides preconditions to involve the pupils into the activities of planning, implementing, and evaluating the education process. Conscious formulation of educational goals in the context of a learning community together with others, as well as taking decisions towards those goals accumulate energy needed to carry out activities and overcome problems, and provide encouragement to plan new, higher, goals.

The research reveals that the following two types of empowerment principles are applied in the process of inclusive education: direct empowerment – positive generalizations; information presented openly; providing freedom to decide and accepting the decision; indirect empowerment – demonstrating the teacher’s interest; encouragement; creating conditions to look for solutions; teacher’s contribution to the pupil’s successful result; search for solutions in groups. In order to achieve the realization of inclusive education in schools, it is obligatory to shift from instruction oriented teaching of pupils to trust-based empowerment of the pupils to learn.
The Importance of Educational Level and Occupation to Adjustment to Disability Among Mobility Impaired People
Authors: Alčiauskaitė Laura , Šinkariova Liuda
Published: October 2018

Every disability results in array of reactions ranging from negative affectivity to successful acceptance of disability among mobility impaired people. Previous studies suggest that educational level and occupation are potential variables affecting adjustment to disability but there is a lack of research analysing how these variables are related to individual’s reactions to disability.

The aim of the study was to assess the importance of educational level and occupation to adjustment to disability among mobility impaired people.

The study sample included 275 mobility impaired individuals, aged between 18 and 79. Their adjustment to disability was assessed using two questionnaires: 1) Reactions to Impairment and Disability Inventory (Livneh & Antonak, 1990), measuring six emotional reactions to disability: denial, depression, internalized anger, externalized hostility, acknowledgement and adjustment; 2) Acceptance of disability scale (Linkowski, 1971).

The results revealed that individuals with higher educational level reported less internalized anger and externalized hostility compared to individuals with lower educational level. In addition, employed individuals expressed less depression and internalized anger and greater adjustment than unemployed individuals. Individuals who were students at the time reported less depression and greater denial, acknowledgement and adjustment to disability compared to those who were unemployed. Students also perceived greater externalized hostility than employed individuals. The results of linear regression indicated that employment and student status but not disability related variables significantly explained the variance of acceptance of disability.
The Reflection Experience of Future Teachers as Professional Improvement Tool
Authors: Žibėnienė Gintautė , Barkauskaitė Marijona
Published: October 2018

In the article is presented a qualitative research, which was based on the methodological provisions of social constructivism and theoretical assumptions of social constructivism. The main topic of the article is to discuss the experiences of future teachers (pedagogy studies students), reflections. Main purpose is to discuss the reflection experience of future teachers, as professional improvement tool. The research was conducted in 2016–2017 December, the research involved 17 students of pedagogy studies. Research data collection and analysis methods: document analysis and analysis of scientific literature, open question, content analysis. There are two main directions of reflections of future teachers: 1) personal reflection experiences and 2) the benefits of reflection for the students. The personal reflection experience of future teachers is unconscious discovery of a person, a change from the negative attitude to positive. Also it is not always a pleasant and easy experience, self-analysis and improvement, the emerging need for reflection in practice. As well in “the personal reflection experience of future teachers” idea, we can include the linking of reflection results with life and professional success and last but not least, the need to apply different reflections methods based on insights on the change in the evaluation of personal achievements from the experience provided for possible failures and threats to reflection. Future teachers are going to use reflection techniques with student in a purpose of helping to learn and understand the meaning of learning. Also it helps to develop responsibility, teach a student and it is a good way to develop critical thinking. Moreover, the last benefit of these techniques is that fact that it makes the process of learning more interesting.

Dalam aplikasi industri, salah satu kekurangan poli asam laktat (PLA) adalah kristalisasi yang lambat, sehingga meneyebabkan waktu yang lebih lama untuk mengolah PLA dibandingkan dengan polimer konvensional seperti polipropilen. Penelitian ini mengevaluasi pengaruh penambahan pengisi atau aditif terhadap laju kristalisasi PLA. PLA dilarutkan dalam diklorometana (DCM) dan dicampur dengan nucleating agent (seng asam fenilfosfonat atau talk) atau pelunak (triasetin) pada konsentrasi yang berbeda diikuti dengan pengeringan pada suhu kamar selama 24 jam dan  pengeringan oven selama 2 jam pada suhu 80 °C. Campuran kering PLA  ditempa panas pada 180 °C selama 10 menit. Differential Scanning Calorimetry (DSC) dilakukan untuk mengevaluasi tingkat kristalisasi. Hasil studi menunjukkan bahwa penambahan pengisi atau aditif mempercepat proses kristalisasi PLA. Asam seng fenilfosponat (PPA-Zn) adalah pengisi yang paling efektif untuk mempercepat laju kristalisasi PLA.
BEREKETLİ HİLAL'İN KUZEYİNDE YENİ ARAŞTIRMALAR: ADIYAMAN BÖLGESİ
Authors: EZER Sabahattin
Published: October 2018

Adıyaman, Bereketli Hilal’in en kuzeyinde, prehistorik dönemlerden itibaren kesintisiz bir şekilde yerleşilmiş bir bölgedir. Burada yapılan Prehistorik ve Protohistorik dönemlere ait çalışmaların tamamına yakını Adıyaman’ın batısında, Fırat Vadisi’nde gerçekleşmiştir. Aşağı Fırat Projesi kapsamında 1977’de başlatılan yüzey araştırmaları bazı kurtarma kazıları ile devam etmiştir. Bölgede yapılan son yüzey araştırmaları ise 1985-1988 yılları arasında Tille kazı ekibi tarafından gerçekleşmiştir. Adıyaman’ın prehistorik ve protohistorik dönemlerine ilişkin yeni çalışmalar, 25 yıl aradan sonra, 2013 yılında tekrar başlatılmış ve halen sürdürülmektedir. Öncelikli olarak Merkez İlçe’de başlayan çalışmalar daha sonra Adıyaman’ın batısına, sonrasında kuzeyine yönelmiştir. Son olarak, Adıyaman’ın doğu tarafında yüzey araştırmalarına devam edilmiştir. 2016 yılına kadar 78 adet arkeolojik sit incelenmiştir. Bunlardan 38 tanesi, ilk olarak araştırma ekibimiz tarafından arkeoloji literatürüne kazandırılmıştır. Yapılan çalışmalar sonucunda M.Ö. 3. ve 2. bin ağırlıklı yerleşmeler saptanmış olsa da Neolitik’ten başlayarak Demir Çağı’na kadar ki süreç izlenebilmiştir. Kuşkusuz, Adıyaman K. Suriye kültür bölgesinde yer almaktadır. Ancak bunun yanında Doğu Anadolu ile ilişkileri ortaya koyan seramik buluntularda ele geçmiştir. Yüzey araştırmalarında ele geçen Halaf türü seramikler, M.Ö. 3. bine ait cyma-recta, caliciform, Suriye şişesi tipinde kaplar ve M.Ö. 2. bine ait “ağzı yivli kaplar”, komşu bölgelerle olan kültürel birlikteliği ortaya koymaktadır. Adıyaman’ın orta ve kuzey yerleşmelerinde ele geçen Karaz türü seramik ise, Doğu Anadolu Bölgesi ile olan ilişkileri gösterir. Neredeyse bütün yerleşmelerde ele geçen çakmaktaşı çekirdek ve dilgiler, bölgenin çakmaktaşı kaynakları açısından çok zengin olduğunu ortaya koymaktadır. Adıyaman’da, Plaeolitik Çağ’dan başlayarak bütün dönemlerin kesintisiz bir şekilde saptanmış olması bölge ve araştırmacılar için son derece önemlidir.

Synthego chemically modified synthetic sgRNAs are of exceptional quality and consistently drive high editing efficiencies. Data that demonstrate editing efficiency in HEK293 cells are included.
ROW AND PLANT SPACING EFFECTS ON THE YIELD AND YIELD COMPONENTS OF SAFFLOWER IN A MEDITERRANEAN-TYPE ENVIRONMENT
Authors: CALISKAN Sevgi , CALISKAN Mehmet Emin
Published: October 2018

This study was conducted to determine the effects of inter-row and intra-row spacing on two safflower

cultivars under the Eastern Mediterranean conditions in Hatay, Turkey during 2010-2011 and 2011-2012

growing seasons. The field experiments were laid out in a split split plot design with three replications with two

cultivars (Dincer and Remzibey) as a main plots, four inter-row spacing (15, 30, 45 and 60 cm) as sub-plot and

three intra-row spacing (5, 10 and 15 cm) as sub-subplot. Seed yield and yield-related traits were lower in both

cultivars in 2012 comparing to previous year probably due to lower rainfall. Two years’ data indicated that

cultivars, inter-row and intra-row spacing significantly affected growth, yield and yield components of

safflower. Increasing plants population reduced yield components and yield of individual plants, but increased

yield per unit area. Low plant density resulted in significantly higher branches/plant, heads/plant, seeds/head.

The highest seed yields per hektare were obtained with sowing safflower cultivars at 5 cm intra-row spacing in

45 cm spaced rows in 2011, and in 30 cm spaced rows in 2012. Our results indicated that higher plant density

can be advantageous under yield limiting conditions while sowing winter safflower at 45 x 5 cm inter- and

intra-row spacing can be recommended for regular seasons in Mediterranean-Type Environments. 
IDENTIFICATION OF NEW QTL CONFERRING RESISTANCE TO ANTHRACNOSE (ASCOCHYTA RABIEI) IN A RIL POPULATION OF CHICKPEA
Authors: YILDIRIM Arzu , KAHRAMAN Abdullah , MUEHLBAUER Frederick John , TANYOLAC Bahattin
Published: October 2018

Ascochyta blight (AB) is a consistent problem affecting large growing areas of chickpea in all countries where

this crop is cultivated. This disease is capable of causing large yield losses under conducive environmental

conditions. To characterize the genetics of resistance to AB in chickpea, a population consisting of 77

recombinant inbred lines (RILs) derived from an inter-specific cross of Cicer arietinum (FLIP84-92C, resistant

parent) x Cicer reticulatum Lad. (PI 599072, susceptible parent) was used. Each RIL and the parents were

inoculated with blight spores by spraying. The RILs were scored for disease reactions under greenhouse

conditions at 20 °C in a 12 h photoperiod. A linkage map was constructed using RAPD markers. Eleven

linkage groups were obtained, of which three were small. The map spanned 889.1 cM with an average marker

density of 10.1 cM. Two QTL were detected on linkage groups 1 and 4, which together explained 31% of the

total phenotypic variation for AB resistance. These markers can improve precision of molecular breeding in

this population. 
Community-University Action Research: Possibilities for Capacity Building
Authors: Mundell Leah , Garza Jorge , Austin Danielle , Arellano-Haring Aaron
Published: October 2018

In this paper, we explore a new university initiative that engages advanced undergraduate students in community-directed, interdisciplinary research where local organizations partner with student inquiry pods to research particular problems. We discuss one partnership with a community organizing group working to support issues important to the immigrant community: access to post-secondary education. This collaboration is expected to build the capacity of students, community members, and the organization itself, yet one of these groups may be privileged over the others at any given time. For whom do these collaborations bolster capacity? Can these collaborations advance social justice for and/or with immigrants?

Giriş ve Amaç:Endoskopik retrograd koloanjiopankreatografi esnasında alınan papilla biyopsisi periampuller bölge tümörlerinin tanısında yaygın olarak kullanılmaktadır. Bu çalışmada, tümörden şüphelenilen olgularda alı-nan papilla biyopsi sonuçlarını değerlendirmeyi amaçladık. Gereç ve Yöntem:Çalışmaya kliniğimizde Ocak 2013 ile Aralık 2014 tarihleri arasında yapılan endoskopik retrograd kolanjiopankreatografi sırasında papilladan biyopsi alınan toplam 48 vaka alındı. Endoskopik retrograd kolanjiopankreatografi ve patoloji raporları, endoskopik retrograd kolanjiopankreatografi sonrası ameliyat/görüntüleme/endoskopik ultrasonografi eşliğinde biyopsi bulguları, bilgisayar veri tabanından retrospektif olarak toplandı. Bu sonuçlara göre hastaların nihai tanıları tespit edildi. Bulgular:Hastaların ortalama yaşı 69.4±13.3 yıl idi. Vakaların 22’si erkek, 26’si kadındı. Patoloji sonuçları-na göre hastaların 12’si (%25) malignite pozitifti, 7’sinde (%14.6) adenomatöz değişiklikler saptanmıştı, 23’ünde (%47.9) malignite negatifti ve 6’sında (%12.5) malign/benign ayrımı yapılamamıştı. Papilla biyopsisi sonuçlarına göre 1 hastaya ampullektomi ve 6 hastaya Whipple operasyonu uygulandı. Nihai tanılara göre hastaların 19’unun (%39.6) malign, 5’inin (%10.4) adenom, 24’ünün (%50) malignite negatif olduğuna karar verildi. Papilla biyopsisinin malignite tanısını öngörmede sensitivitesi %66.6, spesifitesi %100, pozitif prediktif değer %100, negatif prediktif değer %80 ve tanısal doğruluk oranı %85 olarak bulundu. İşlem öncesi alkalen fosfataz, aspartat aminotransferaz, alanin aminotransferaz, total bilirubin ve CA 19-9 düzeyleri ve işlem sırasında alınan parça sayısı malign grupta istatistiksel olarak anlamlı biçimde yüksekti. İlk biyopsileri negatif veya ayrım yapılamayan şeklinde rapor edilen ve papilla biyopsisi tekrarlanan 3 olguda da ikinci biyopsi ile nihai tanıya ulaşıldı. Bu olgulardan biri adenokarsinomdu. Sonuç:Ampüller bölge tümörü düşünülen olgularda papilla biyopsisinin tanıya katkısı yüksektir. İlk biyopsi negatif gelse de klinik bulgular varsa, ikinci biyopsinin yapılması yararlı olabilir. Özellikle aspartat aminotransferaz, alanin aminotransferaz, alkalen fosfataz, total bilirubin ve CA 19-9 değerleri yüksek olgularda klinik şüphe varlığında biyopsi yapılmalıdır.
Late Holocene anthropic degradation records in semi-arid environments (NE Spain and NW Argentina)
Authors: Peña-Monné J.L. , Sampietro-Vattuone M.M.
Published: October 2018

Information about Holocene sedimentary records in two semiarid areas in Spain and Argentina was gathered to know the role of the anthropic influence on landscape evolution. In both cases, four aggradational units separated by incision phases have been differentiated. Due to the confluence of anthropic indicators, the H1C subunit (ca. 2.45-ca. 1.5 ka cal BP) in the central sector of the Ebro basin (NE Spain), and the H2B subunit (2.45-ca. 0.6 ka cal BP) in the Tafi valley (NW Argentina) are worthy of attention. In both cases, a soil formed around 2.45 cal BP was degraded, because it was the object of intense overexploitation in the Ibero-Roman period in the Ebro valley and Formative period in Tafí valley. The final results of these processes represented transformations so significant that the landscape was unable to recover posteriorly. In highly vulnerable dryland environments, the establishment of adequate criteria to link strong landscape degradative phases with human activity is of high interest to know de older phases of the Anthropocene or Paleoanthropocene.

Histochemical approaches to the evaluation of the participation of mast cells in the regulation of the fibrous component of the intercellular matrix of skin connective tissue
Authors: Atyakshin D. A.
Published: October 2018

The article presents the data of study of the effectiveness of various combinations of histochemical staining to determine the co-location of mast cells with a fibrous component of the connective tissue of Wistar line laboratory rats skin. The best results are obtained with combination protocols such as metachromatically detection of mast cells in combination with the impregnation with silver or picrofuchsin, brilliant green coloring with the methodology of Van Gieson or picrofuchsin, and aniline blue neutral red. The proposed variants of histochemical protocols can be used to analyze the participation of mast cells in the remodeling of the cell matrix of tissue microenvironment in the development of adaptive and pathological processes. The obtained results contribute to the expansion of currently available scientific ideas about the laws of the process of fibrillogenesis in the extracellular matrix and provide new data on the targeted participation of the components of the mast cell secretome in the molecular mechanisms of fiber formation.

In modern practical health care a large aspect is occupied by PRP-technology, the which effect is provided by growth factors located in alpha granules on the platelet membrane and responsible for the regeneration of connective tissue. The purpose of this study was a morphological assessment of reactive changes in periprosthetic tissue in PRP-technology application. Material and methods . The study was carried out on laboratory rabbits. Experimental animals were divided into two groups of observations - control and experimental. The endoprosthesis was implanted into the anterior region of the abdominal wall. Autoplasma enriched with platelets was injected after implantation under the endoprosthesis twice into experimental animals. A site with an endoprosthesis material was excised for a morphological study. Histological sections were stained with hematoxylin and eosin, according to Van Gieson, and Mallory methods, an immunohistochemical study was performed. The results of the morphometric study were processed using the Statistica v. 8.0. Results. In the experimental group the onset of the proliferative phase of inflammation occurred at an earlier time and provided the formation of a mature connective tissue periprosthetic capsule. By the 10th day of the experiment, a double dominance of the thickness of the capsule was observed in the experimental group. The proportion of cells of fibroblastic differon accounted for 60% of all cells, which resulted in an an increase in the cellular index by 1.6 times. The proliferation index was 2 times greater at all experimental days. Conclusion. The use of PRP-technology in endoprosthetics leads to an earlier formation of a mature periprosthetic capsule, accelerates the survival of the prosthesis and reduces the risk of postoperative complications.

Authors: Shadlinskaya S. V.
Published: October 2018

The purpose of the study was to identify the structural features of the small glands of the vestibule vagina with some anomalies in the development of internal genital organs. Material and methods. Glands of the vaginal vestibule of 18 newborn girls with internal genital anomalies were examined histologically using light microscopy. The comparison group consisted of 10 cases of newborn girls without pathological changes in the urogenital apparatus. After separation of the vestibule from the surrounding structures from the organ wall, longitudinal fragments were cut out, which were fixed in formalin and, after posting on alcohols, an increasing concentration was poured into paraffin. Sections 5-7 microns thick were stained with hematoxylin-eosin and by Van Gieson. Craigberg reaction was also conducted. The digital data obtained during the study were subjected to statistical processing. Results. The analysis showed that, in norm, the small glands of the vestibule of the child's vagina at the time of birth are capable of active secretion. In newborn girls with anomalies of the uro-genital system, the thickness and area of the initial section, the number of initial parts, the area of the initial part on the cut, the number of glandulocytes in the initial part of the glands decrease. There is an increase in the lumen of the common gland duct. Conclusions. Normally, small glands of the vestibule in the newborn are fully formed. With anomalies of the internal genital organs, significant destructive changes in the glandular apparatus of the vestibule are revealed. In contrast to the norm, the initial parts of the glands on the longitudinal sections are deformed. The thickness and area of the initial section decreases, the number of initial parts, the area of the initial part on the cut, the number of glandulocytes in the initial part of the glands.

Knowledge Component of a Multiagent Distributed Decision Support System
Authors: Stegmayer Georgina , Caliusco María Laura , Chiotti Omar , Galli María Rosa
Published: October 2018

We have developed a distributed DSS capable to working in a dynamic way. That is, when a domain of an organization needs a new kind of information, the system looks for this information. This system is based on the usage of mobile agents, which receive the user's queries and visit the appropriate DSS domains to gather the required information. The system itself must analyze where this information can be generated. To make this decision there is an intelligent agent (the Router) with a knowledge base (KB) where the information managed by each domain is represented. In this work, we present a strategy to obtain the initial data to be stored in the KB, a knowledge retrieval mechanism from the KB, and a learning mechanism so that the KB and the DSS operation can be continually improved. The proposed learning process is an interpretative case-based reasoning, which uses a set of rules to analyze the results of the information retrieval process and modifies the content of the router KB. Some examples are presented to illustrate the learning mechanism.

Currículo de matemática na educação do campo: panoramas e zoons
Authors: Sachs Línlya
Published: October 2018

Este artigo tem como objetivo apresentar e discutir maneiras de entender o currículo de matemática na educação do campo, como uma atualização da pesquisa realizada por Barbosa (2014). Para isso, foi feito um levantamento de publicações acadêmicas, em um periódico, em um evento e em dissertações e teses, que aproximem a educação do campo e a educação matemática. A partir da metáfora da fotografia, são feitas imagens panorâmicas, que buscam dar uma ideia do todo. Com a análise dessas publicações, foram constituídas quatro categorias – chamadas de zoons, que focam aspectos relevantes do currículo escolar. A primeira delas entende que é importante “partir da realidade” para chegar ao objeto matemático; a segunda sugere que sejam incluídos nos currículos os “saberes locais”; a terceira afirma que não deve haver especificidade no programa curricular de matemática dessas escolas; e, por fim, a quarta compreende que a escola deveria, também, oferecer uma formação técnica para o trabalho rural.
Afetividade e o ensino de Matemática: uma história de mediação pedagógica no Ensino Médio
Authors: Leite Sérgio Antônio da Silva , Lima Valéria De Araújo
Published: October 2018

Este artigo baseia-se em pesquisa cujo objetivo foi identificar aspectos de uma prática pedagógica que podem ser considerados facilitadores do processo de aproximação afetiva positiva entre o aluno e os conteúdos de um campo específico do conhecimento: a matemática. Os dados foram coletados através de sessões de observação da prática pedagógica de um professor de matemática, em uma turma de primeiro ano do Ensino Médio, além de entrevistas com o mesmo e com alguns dos alunos. A partir do material coletado, foram criados núcleos temáticos com o intuito de reproduzir os aspectos identificados nos dados que possam ser interpretados como fatores de natureza afetiva e que, portanto, produzem impactos positivos ou negativos nos alunos. Os dados sugerem, fortemente, que as relações que se estabelecem entre sujeito (aluno) e objeto (conteúdos matemáticos) são determinadas basicamente pela mediação do professor, sendo que tais relações são, também, de natureza afetiva.
Uma análise do Projeto de formação profissional de professores privilegiada pelo PROFMAT
Authors: Caldatto Marlova Estela , Fiorentini Dario , Pavanello Regina Maria
Published: October 2018

Este estudo visa analisar e discutir o projeto acadêmico do Programa de Mestrado Profissional em Matemática em Rede Nacional (PROFMAT), destacando, sobretudo, a natureza dos conhecimentos formativos que são priorizados por essa política pública de desenvolvimento docente. Tendo por base a teorização de Gimeno Sacristán, esse projeto foi considerado neste artigo o currículo oficial desse programa, que foi analisado a partir de uma perspectiva curricular crítica e de pesquisas que investigam o “conhecimento especializado do professor de matemática”. As análises evidenciaram que esse programa de pós-graduação privilegia a disseminação de códigos e conhecimentos vinculados fortemente à prática do matemático profissional, ao mesmo tempo que não aborda conhecimentos referidos pela literatura especializada como sendo fundamentais para a prática do professor que ensina matemática na educação básica.
Self-Reported Postoperative Opioid-Prescribing Practices Following Commonly Performed Orthopaedic Hand and Wrist Surgical Procedures

Published: October 2018

Background:

Although orthopaedic surgeons have been shown to prescribe excessive amounts of opioid analgesics postoperatively, the degree in which surgical trainees contribute to this trend is unknown. The purpose of this study was to compare self-reported opioid-prescribing behavior, factors influencing this behavior, and perceptions of patient opioid utilization and disposal between hand surgeons and trainees.

Methods:

Attending hand surgeons and trainees in hand, orthopaedic, and plastic surgery programs were invited to participate in a web-based survey including demographic characteristics; self-reported prescribing behavior specific to 4 procedures: open carpal tunnel release, trigger finger release, thumb carpometacarpal arthroplasty, and distal radial fracture open reduction and internal fixation; and perceptions and influencing factors. Analgesic medications were converted to morphine milligram equivalents and were compared across groups of interest using independent t tests or analysis of variance for each procedure.

Results:

A total of 1,300 respondents (266 attending surgeons, 98 fellows, 708 orthopaedic residents, and 228 plastic surgery residents) were included. Surgeons reported prescribing fewer total morphine milligram equivalents compared with residents for all 4 procedures. Personal experience was the most influential factor for prescribing behavior by surgeons and fellows. Although residents reported that attending surgeon preference was their greatest influence, most reported no direct opioid-related communication with attending surgeons.

Conclusions:

Residents self-report prescribing significantly higher morphine milligram equivalents for postoperative analgesia following commonly performed hand and wrist surgical procedures than attending surgeons. Poor communication between residents and attending surgeons may contribute to this finding. Residents may benefit from education on opioid prescription, and training programs should encourage direct communication between trainees and attending surgeons.
High-Energy Pelvic Ring Disruptions with Complete Posterior Instability
Authors: Verbeek Diederik O. , Routt Milton L.
Published: October 2018

* Accurate reduction and rigid internal fixation of anterior pelvic ring injuries enhances overall stability of the pelvic ring and augments posterior fixation constructs.

* Closed reduction techniques can be highly effective for unstable pelvic ring disruptions and are preferable over open reduction methods.

* Percutaneous iliosacral screw fixation is a generally safe and effective method of fixation of posterior pelvic ring injuries.

* Multiple and longer (transiliac-transsacral) screws at both sacral segments are required to create a stronger screw construct for complete posterior pelvic disruptions.

* Lumbopelvic fixation substantially augments iliosacral screw fixation and is particularly useful for comminuted transforaminal sacral fractures with associated vertical instability.
Physical Activities That Cause High Friction Moments at the Cup in Hip Implants
Authors: Bergmann Georg , Bender Alwina , Dymke Jörn , Duda Georg N. , Damm Philipp
Published: October 2018

Background:

High friction moments in hip implants contribute to the aseptic loosening of cementless cups, of which there are approximately 100,000 cases per year; sustained joint loading may cause such high moments. The most “critical” physical activities associated with sustained joint loading were identified in this study.

Methods:

Friction moments in the cup were telemetrically measured about 33,000 times in the endoprostheses of 9 subjects during >1,400 different activities. The highest moments were compared with the cup’s fixation stability limit of approximately 4 Nm.

Results:

A total of 124 different activities caused friction moments meeting or exceeding the critical limit, with the highest value of 11.5 Nm. Most involved sustained high contact forces before or during the activity. The highest peak moments (6.3 to 11.5 Nm) occurred when moving the contralateral leg during 1-legged stance, during breaststroke swimming, muscle stretching, 2-legged stance with muscle contraction, and during static 1-legged stance. The median moments were highest (3.4 to 3.9 Nm) for unstable 1-legged stance, whole-body vibration training, 2-legged stance with an unexpected push at the upper body, 1-legged stance while exercising the contralateral leg, and running after 2-legged stance.

Conclusions:

Frequent unloading plus simultaneous movement of the joint are required to maintain good joint lubrication and keep the friction moments low. Frequent, sustained high loads before or during an activity may cause or contribute to aseptic cup loosening. During the first months after hip arthroplasty, such activities should be avoided or reduced as much as possible. This especially applies during postoperative physiotherapy. Whether these guidelines also apply for subjects with knee implants or arthrotic hip or knee joints requires additional investigation.

Clinical Relevance:

The risk of aseptic cup loosening may be reduced by avoiding sustained loading of hip implants without periodic joint movement.

Although biological N fixation (BNF) is a key process for economic cultivation of soybean [Glycine max (L.) Merr.], the trait is often neglected in breeding programs, mainly due to difficulties in evaluating nodulation and N fixation parameters. We used a genotyping‐by‐sequencing approach to provide a dense genome‐wide marker coverage with 1448 single nucleotide polymorphisms (SNPs) distributed broadly across the chromosomes of a soybean population. The mapping population was composted of 113 F7:8 recombinant inbred lines, obtained by single‐seed descent method, derived from crossing of soybean cultivars ‘Bossier’ (high BNF capacity) and ‘Embrapa 20’ (medium BNF capacity). The traits evaluated were nodule number (NN), nodule dry weight (NDW), average NDW (ANDW; i.e., NDW/NN), and shoot dry weight (SDW). A genetic map was constructed with 1448 SNPs that generated 35 linkage groups totaling 1793 cM, thus covering ∼72% of the genome based on the consensus linkage map. The estimated heritability for NN, NDW, ANDW, and SDW was 0.41, 0.30, 0.30, and 49.11, respectively. Inclusive composite interval mapping identified two significant quantitative trait loci (QTLs) for ANDW at 67 cM on chromosome 13, with a logarithm of odds (LOD) score of 4.66. The additive effect of this locus was −0.31 mg nodule−1, and it explained 18.13% of the phenotypic variation. Another QTL was identified for SDW at 24 cM on chromosome 19 and exhibited an LOD score of 3.93. The additive effect was of 0.57 g plant−1, and it accounted for 14.93% of the phenotypic variation. Additive genetic effects contribute to the final phenotype. In the present study, Embrapa 20 was the major contributor to ANDW, and Bossier was the major contributor to SDW. The latter was previously reported using simple sequence repeat markers.
Effective universality in quantum gravity
Authors: Eichhorn Astrid , Labus Peter , Pawlowski Jan M. , Reichert Manuel
Published: October 2018

We investigate the asymptotic safety scenario for a scalar-gravity
system. This system contains two avatars of the dynamical Newton
coupling, a gravitational self-coupling and a scalar-graviton coupling.
We uncover an effective universality for the dynamical Newton coupling
on the quantum level: its momentum-dependent avatars are in remarkable
quantitative agreement in the scaling regime of the UV fixed point. For
the background Newton coupling, this effective universality is not
present, but qualitative agreement remains.
