Core Ideas

Feijoa fruit combine unique flavor and medicinal properties.

The Brazilian feijoa collection exhibit high variability in fruit traits.

Years was the major effect to all fruit trait phenotype in south of Brazil.

The aim of the present work was to physicochemically characterize the fruits of accessions of feijoa [Acca sellowiana (O. Berg.) Burret] active germplasm bank (BAG), located in São Joaquim, Brazil. The identification of accessions with desirable fruit traits will facilitate species breeding and cultivation. During seven harvests (2004–2017), 10 fruits per plant of 229 accessions were evaluated for fruit diameter, length and weight, skin and pulp weight, skin thickness, pH, titratable acidity, and soluble solids content, in addition to the qualitative descriptors insertion of sepals, fruit shape, sheen of skin, vacuum, color of skin and pulp, and texture and roughness of the skin. Descriptive statistics, correlations, and a multivariate analysis were applied to better understand the nature and magnitude of the variables. The mean +1SD was used to identify the best accessions for breeding purposes. Active germplasm bank accessions revealed significant phenotypic diversity for the physicochemical characteristics of the fruits, and the year effect represented the largest contribution to the variance for all evaluated characteristics, except fruit length. The characteristics total fruit weight, fruit diameter, and skin thickness are strongly related to pulp yield (%). There is high phenotypic diversity in accessions of feijoa conserved in the São Joaquim BAG, which will allow different traits of this species to be genetically improved.
Quantum null energy condition and its (non)saturation in 2d CFTs
Authors: Ecker Christian , Grumiller Daniel , van der Schee Wilke , Sheikh-Jabbari Shahin , Stanzer Philipp
Published: March 2019

We consider the Quantum Null Energy Condition (QNEC) for holographic
conformal field theories in two spacetime dimensions
(CFT_22).
We show that QNEC saturates for all states dual to vacuum solutions of
AdS_33
Einstein gravity, including systems that are far from thermal
equilibrium. If the Ryu-Takayanagi surface encounters bulk matter QNEC
does not need to be saturated, whereby we give both analytical and
numerical examples. In particular, for CFT_22
with a global quench dual to AdS_33-Vaidya
geometries we find a curious half-saturation of QNEC for large
entangling regions. We also address order one corrections from quantum
backreactions of a scalar field in AdS_33
dual to a primary operator of dimension h
in a large central charge expansion and explicitly compute both, the
backreacted Ryu–Takayanagi surface part and the bulk entanglement
contribution to EE and QNEC. At leading order for small entangling
regions the contribution from bulk EE exactly cancels the contribution
from the back-reacted Ryu-Takayanagi surface, but at higher orders in
the size of the region the contributions are almost equal while QNEC is
not saturated. For a half-space entangling region we find that QNEC is
gapped by h/4h/4
in the large h expansion.
O ENSINO DE CIÊNCIAS E A APRENDIZAGEM SIGNIFICATIVA – REFLEXÕES SOBRE UMA AULA PRÁTICA COM A UTILIZAÇÃO DE INSETOS
Authors: Antiogenes Luiz , Praça Andrea Velloso da Silveira
Published: March 2019

A presente discussão objetiva aprofundar nossas reflexões sobre o conceito de aprendizagem significativa e levantar as possibilidades de mudança de nossa prática junto aos alunos da escola pública. Nossas inquietações sobre o ensino de ciências têm origem nas discussões e estudos teóricos sobre a aprendizagem significativa efetivados no PPGEC da UNIGRANRIO. Trazemos para nossa reflexão o resultado do estudo realizado, com o apoio do livro didático e de exemplares vivos de grilos, junto a 139 alunos de quatro turmas do 8º ano do Ensino Fundamental de uma escola pública situada no espaço de uma antiga fazenda no Município de Nilópolis - RJ. Os resultados possibilitaram ampliar e questionar nossa compreensão sobre aprendizagem significativa, avançarmos e questionarmos juntos aos professores da escola a utilização do livro didático como única estratégia de ensino, possibilitou, internamente, no espaço da escola, a reflexão sobre o que seja ensinar e aprender e de que forma os professores podem utilizar, como estratégias, os recursos existentes na escola. O entendimento de que o significado da aprendizagem está no sujeito e não nas estratégias, abre novas possibilidades e pensar e repensar os argumentos que circulam no interior da escola.

Published: March 2019

O objetivo do estudo foi propor estratégias que colaborem na construção de políticas educacionais a serem desenvolvidas nas instituições de ensino superior que estimulem à adoção de comportamentos saudáveis. Método: A pesquisa foi realizada em uma instituição de Ensino Superior do Ceará- Brasil, com 324 universitários, ingressantes e concluintes nas áreas da saúde, humanas e exatas. O instrumento utilizado foi o ISAQ-A. A coleta correu em Janeiro e Fevereiro/2017. Resultados e Discussão: As informações obtidas na fase exploratória deflagra que os estudantes, em sua maioria, estão insatisfeitos com a imagem que têm de si e não apresentam padrões considerados saudáveis no que se refere aos hábitos alimentares, a prática de atividades físicas no lazer e sobrepeso.  A maior permanência no ambiente universitário mostra-se associado a chances de inatividade física e outros comportamentos de risco. Existe uma forte relação entre estar muito estressado com o rendimento acadêmico menor. As estratégias propostas foram: a participação dos estudantes como protagonistas de uma cultura saudável, espaços disponíveis para a prática de atividade física, a implantação de um restaurante universitário e o fortalecimento do Núcleo de Apoio ao Discente, observando o perfil do ingressante e as tendências ao longo da vida universitária, escuta qualificado e formação de grupos de apoio. Conclusão: as tendências observadas traz um contexto preocupante relativo a fatores de risco presentes na população universitária, as estratégias propostas, fortalecem o conceito que a Universidade deve ser um espaço promotor de culturas saudáveis e novas pesquisas são necessárias para aprofundar esta temática.

Published: March 2019

Por meio deste texto apresentam-se resultados de um trabalho realizado no âmbtio do curso de Mestrado em Educação Profissional e Tecnológica, mantido pela Universidade Federal de Santa Maria, o qual consistiu em analisar as percepções de egressos do Programa Especial de Graduação para Formação de Professores para a Educação Profissional em relação à sua formação e atuação enquanto professores. Buscou-se identificar e analisar as percepções de um grupo de egressos do período compreendido entre 2010 e 2015 que atuam ou atuaram na docência. Para a coleta de dados utilizou-se um questionário semi-estruturado online e entrevistas. Foram enviados 952 questionários e realizadas quatro entrevistas. As informações foram selecionadas de acordo com os critérios de inclusão e exclusão estabelecidos para a pesquisa e submetidas à análise do conteúdo na perspectiva de Bardin (1977). Em termos gerais, os resultados demonstraram que os egressos indicam compreenderem as principais dimensões envolvidas na atuação docente e a necessidade de inovação e dinamismo nas aulas. Por outro lado, percebeu-se, pelos relatos, que suas práticas continuam a pautarem-se pela reprodução de procedimentos tradicionais, o que nos levou a pensar que, neste caso específico, não há uma relação, direta e necessária, entre a freqüência a um curso de formação de professores e um melhor desempenho profissional docente.
Palavras-chave: ensino profissionalizante, políticas de formação docente, percepções de egressos.
CONCEPÇÕES ACERCA DA HISTÓRIA E EPISTEMOLOGIA DA BIOLOGIA APRESENTADAS EM UMA COMUNIDADE DE PRÁTICA.
Authors: Lima Murilo Del Bianco , Corazza Maria Júlia , Justina Lourdes Aparecida Della
Published: March 2019

A Biologia se constituiu como uma ciência do conhecimento, passando por períodos de descrédito nos quais não era considerada uma ciência segmentada em várias áreas de mesmo nível de reconhecimento da Física e a Química. Tais contextos acabaram influenciando a construção da disciplina Biologia, que se caracteriza como fragmentada, descritiva e memorística. A presente pesquisa, de natureza qualitativa, buscou investigar as concepções acerca da epistemologia da Biologia elucidadas por participantes de uma Comunidade de Prática, constituída por professores pesquisadores, pós-graduandos, graduandos e professores da educação básica. Os discursos dos sujeitos da pesquisa foram obtidos por meio de gravações das reuniões referentes aos temas da epistemologia da ciência, posteriormente transcritos e tratados com o auxílio da Análise Textual Discursiva. O tratamento dos dados pela ATD possibilitou a emergência de duas categorias, Biologia ou Ciências Biológicas, Biologia: construção histórica e autonomia, que possibilitaram a construção de um metatexto sobre a natureza da Ciência Biologia. Na visão dos participantes, a Biologia se caracteriza como uma ciência autônoma no presente momento, porém ainda não se encontra completamente unificada.

Wojna sprawiedliwa i wojna święta: raz jeszcze
Authors: Walzer Michael
Published: March 2019

Artykuł omawia argumenty Pawła Włodkowica, polskiego filozofa/teologa z XV wieku, dotyczące wojen etycznie usprawiedliwionych (ius ad bellum). Autor opowiada się za przyjęciem twierdzenia Włodkowica, zgodnie z którym rozum naturalny wyznacza granice dla uzasadnionych działań zbrojnych, a w szczególności zakazuje wszczynania wojen świętych, takich jak krucjaty Zakonu Krzyżackiego, wykluczając tym samym również wojny prowadzone przez współczesnych bojowników dżihadu. Zakazuje on także prowadzenia operacji militarnych wspieranych przez bojowo nastawionych rzeczników ideologii świeckich.
Wojna etycznie usprawiedliwiona w świetle katolickiej nauki społecznej
Authors: Skorowski Henryk
Published: March 2019

Artykuł prezentuje podstawowe założenia filozoficzno-moralne leżące u podłoża ocen działań militarnych formułowanych w obrębie katolickiej nauki społecznej. Wskazując na ciągłość nauczania Kościoła odnoszącego się do etycznego aspektu konfliktów zbrojnych oraz jego głębokie osadzenie w wielowiekowej tradycji filozofii chrześcijańskiej, autor zwraca uwagę na uwidaczniające się we współczesnym stanowisku Kościoła przesunięcie akcentu z przypisywania wartości wojnie jako takiej na uzasadnianie konieczności obrony pokoju – w określonych warunkach obejmującej również zastosowanie środków militarnych.
EDXRF Spectrometry and Complementary Non-Destructive Analytical Techniques in the Archaeometric Study of Copper Artefacts
Authors: S. Katsifas Christos , A. Zachariadis George
Published: March 2019

Background:

For more than a decade, Energy Dispersive X-Ray Fluorescence (EDXRF) spectrometry is the primary analytical technique in archaeometric research and especially in the study of ancient copper artefacts. EDXRF has established itself as the fundamental archaeometric analytical technique because of features like: the ability to analyze samples in a non destructive or non invasive way, no requirements for sample preparation, portability, in situ analysis, simultaneous determination of many elements and finally its easy in use. At the same time there is an explosion of related research publications which provide new possibilities to museums and archaeology scientists. On the other hand, due to its limitations it cannot provide information for every analytical question.

Objective:

The goal of this article is to present an overview of the capabilities of the contemporary EDXRF spectrometry for the study of ancient copper artifacts and the necessity to be implemented, depending on the analytical question, in correlation with complementary analytical techniques which are presented through related case studies.

Conclusion:

The demand for studying artefacts in situ, the evolution of the instrumentation and the access of more scientists (historians, archaeologists, curators etc.) to archaeometry will maintain EDXRF spectrometry as the central analytical technique. Limitations like inability for light elements detection, penetration depth, low (relatively) sensitivity can be partially overcome with the implementation of other analytical techniques which will provide complementary information. Moreover, progress in non-invasive analysis and new portable instruments combining elemental and molecular techniques expand significantly the capabilities of in situ analysis.
Random Black Hole Attack Modelling and Mitigation Using Trust- Confidence Aware OLSR in MANETs for Private Data Communications
Authors: Adoni Kirti A. , S. Tavildar Anil , K. Warhade Krishna
Published: March 2019

Background and Objective:

Random Black Hole (BH) attack significantly degrades MANET’s
performance. For strategic applications, the performance parameters like Packet Delivery Ratio,
Routing Overheads, etc. are important. The objectives are: (a) To model random BH attack, (b)
To propose a routing strategy for the protocol to mitigate random BH attack, (c) To evaluate and
compare the network performance of modified protocol with the standard protocol.

Methods:

The random BH attack is modelled probabilistically. The analysis is carried out by varying
Black Hole Attack (BHA) time as Early, Median, Late occurrences and mix of these three categories.
The blocking performance is also analysed by varying the percentages of malicious presence in the
network. Normal Optimized Link State Routing (OLSR) protocol is used to simulate the MANET
performance using a typical medium size network. The protocol has then been modified using Trust-
Confidence aware routing strategy, named as TCAOLSR, with a view to combat the degradations
due to the random BH attack.

Results:

The random behavior of Black Hole attack is analyzed with all the possible random parameters,
like deployment of mobile nodes, number of malicious nodes and timing instances at which these
nodes change their state. From the results of individual type- Early, Median and Late, it is observed
that the TCAOLSR protocol gives stable performance for Packet Delivery Ratio (PDR) and
Routing Overheads (RO), whereas for OLSR protocol PDR gradually reduces and RO increases. For
individual and mix type, Average Energy Consumption (AEC) per node increases marginally for
TCAOLSR protocol. For the mix type, PDR for TCAOLSR is 40-60% better whereas RO for
TCAOLSR is very less compared to OLSR protocol. The efficacy of the TCAOLSR protocol remains
stable for different categories of BH attack with various percentages of malicious nodes compared
to OLSR with the same environment.

Conclusion:

Simulations reveal that the modified protocol TCAOLSR, effectively mitigates the network
degradation for Packet Delivery Ratio and Routing Overheads considerably, at the cost of a slight increase
in Average Energy Consumption per node of the network. Efficacy of the OLSR and TCAOLSR
protocols has also been defined and compared to prove robustness of the TCAOLSR protocol.

Background:

Wine tourism is one of the tourism components adopted as
part of Portugal’s strategy due to its eminence as a wine producer. Such strategy
has received great prominence in recent years and aims to promote regional
development from an economic, social, cultural and environmental perspective. The
aim of this study was to understand the entrepreneur profile in this sector.

Methods:

The study uses a qualitative, case study methodology with data analysis
and triangulation. In this study, a literature review of scientific studies was carried
out on the scientific knowledge in the area of study from a critical perspective and
an interview was conducted where qualitative data were collected.

Results and Discussion:

The entrepreneurs have shown the following characteristics:
initiative, innovation capability, optimism, creativity, creative energy, tenacity, selfconfidence,
capability for long term involvement with the project, and learning
capacity.

Conclusion:

The study shows that most entrepreneurs state that they have
established partnerships with other companies, particularly with restaurants,
catering businesses, hotel units, tourism companies and companies that organize
tours. This is one of the factors of economic importance recognized by another
study which enables increased prominence of the company and widens the value of
wine tourism.

A study to evaluate the impact of a 21-day school brushing intervention on the knowledge, behaviour and oral health of schoolchildren (Preprint)
Authors: Melo Paulo , Malone Sinead , Rao Arathi , Fine Charlotte
Published: March 2019

BACKGROUND

The World Health Organization reports that dental cavities affect 60-90% of children globally. FDI World Dental Federation and Unilever Oral Care have developed public health programmes to improve brushing habits over their 12-year partnership. The last of these (Phase III) named Brush Day & Night aimed to educate children in brushing twice daily with a fluoride toothpaste.

OBJECTIVE

In Phase IV of the partnership, we aim to evaluate the impact on the knowledge, behaviour and toothbrushing habits in schoolchildren aged 6-9 years old, after a 21-day school programme and compare with baseline and a control group. The enduring nature of the programme will be determined by the inclusion of 8 and 24-week time points.

METHODS

The study is a two-arm, parallel, stratified, cluster randomized trial. Clusters in this study are infant and junior schools in Indonesia and Nigeria. The study aims to recruit 20 schools in each country.

At baseline, children in both intervention and control schools will complete questionnaires and have their oral health assessed via the Simplified Oral Hygiene Index (OHIs) and Decayed Missing and Filled Teeth (DMFT).

Children in the intervention schools will then take part in a structured 21-day Brush Day & Night intervention. The Brush Day & Night programme is an intense education activity designed to establish the habit of brushing day and night with a fluoride toothpaste. The programme involves daily brushing instruction and includes free toothpaste and toothbrushes.

Children in the control schools will be provided with free toothpaste and toothbrushes but will not receive the 21-day intervention.

The questionnaires and OHIs assessment are repeated after 21 days and then again at 8 weeks and 24 weeks later for all participating children.

Parents/Carers/Guardians of all children will complete questionnaires on their own experience and attitudes to oral health and toothbrushing routine at each of the four times points (baseline, 21-day, 8 weeks and 24 weeks).

The study will be conducted by the National Dental Associations of Indonesia and Nigeria.

RESULTS

The study is ongoing. Recruitment of schools started in Indonesia in February 2018 and in Nigeria in April 2018 for the first part of the study. This concluded in Indonesia in September 2018 and in Nigeria in November 2018. The second part of the study (the second half of the schools) started in November 2018 in Indonesia and December 2018 in Nigeria.

CONCLUSIONS

We expect to publish findings from the study by March 2020.
Development of In-Browser Simulators for Medical Education: Introduction of a Novel Software Toolchain (Preprint)
Authors: Šilar Jan , Polák David , Mládek Arnošt , Ježek Filip , Kurtz Theodore W , DiCarlo Stephen E , Živný Jan , Kofranek Jiri
Published: March 2019

BACKGROUND

Simulators used in teaching are interactive applications comprising a mathematical model of the system under study and a graphical user interface (GUI) that allows the user to control the model inputs and visualize the model results in an intuitive and educational way. Well-designed simulators promote active learning, enhance problem-solving skills, and encourage collaboration and small group discussion. However, creating simulators for teaching purposes is a challenging process that requires many contributors including educators, modelers, graphic designers, and programmers. The availability of a toolchain of user-friendly software tools for building simulators can facilitate this complex task.

OBJECTIVE

This paper aimed to describe an open-source software toolchain termed Bodylight.js that facilitates the creation of browser-based client-side simulators for teaching purposes, which are platform independent, do not require any installation, and can work offline. The toolchain interconnects state-of-the-art modeling tools with current Web technologies and is designed to be resilient to future changes in the software ecosystem.

METHODS

We used several open-source Web technologies, namely, WebAssembly and JavaScript, combined with the power of the Modelica modeling language and deployed them on the internet with interactive animations built using Adobe Animate.

RESULTS

Models are implemented in the Modelica language using either OpenModelica or Dassault Systèmes Dymola and exported to a standardized Functional Mock-up Unit (FMU) to ensure future compatibility. The C code from the FMU is further compiled to WebAssembly using Emscripten. Industry-standard Adobe Animate is used to create interactive animations. A new tool called Bodylight.js Composer was developed for the toolchain that enables one to create the final simulator by composing the GUI using animations, plots, and control elements in a drag-and-drop style and binding them to the model variables. The resulting simulators are stand-alone HyperText Markup Language files including JavaScript and WebAssembly. Several simulators for physiology education were created using the Bodylight.js toolchain and have been received with general acclaim by teachers and students alike, thus validating our approach. The Nephron, Circulation, and Pressure-Volume Loop simulators are presented in this paper. Bodylight.js is licensed under General Public License 3.0 and is free for anyone to use.

CONCLUSIONS

Bodylight.js enables us to effectively develop teaching simulators. Armed with this technology, we intend to focus on the development of new simulators and interactive textbooks for medical education. Bodylight.js usage is not limited to developing simulators for medical education and can facilitate the development of simulators for teaching complex topics in a variety of different fields.
Feasibility of Point-of-Care Testing for Influenza Within a National Primary Care Sentinel Surveillance Network in England: Protocol for a Mixed Methods Study (Preprint)
Authors: de Lusignan Simon , Hoang Uy , Liyanage Harshana , Yonova Ivelina , Ferreira Filipa , Diez-Domingo Javier , Clark Tristan
Published: March 2019

BACKGROUND

Point-of-care testing (POCT) for influenza promises to provide real-time information to influence clinical decision making and improve patient outcomes. Public Health England has published a toolkit to assist implementation of these tests in the UK National Health Service.

OBJECTIVE

A feasibility study will be undertaken to assess the implementation of influenza POCT in primary care as part of a sentinel surveillance network.

METHODS

We will conduct a mixed methods study to compare the sampling rates in practices using POCT and current virology swabbing practices not using POCT, and to understand the issues and barriers to implementation of influenza POCT in primary care workflows. The study will take place between March and May 2019. It will be nested in general practices that are part of the English national sentinel surveillance network run by the Royal College of General Practitioners Research and Surveillance Centre. The primary outcome is the number of valid influenza swabs taken and tested by the practices involved in the study using the new POCT.

RESULTS

A total of 6 practices were recruited, and data collection commenced on March 11, 2019. Moreover, 312 swab samples had been collected at the time of submission of the protocol, which was 32.5% (312/960) of the expected sample size. In addition, 68 samples were positive for influenza, which was 20.1% (68/338) of the expected sample size.

CONCLUSIONS

To the best of our knowledge, this is the first time an evaluation study has been undertaken on POCT for influenza in general practice in the United Kingdom. This proposed study promises to shed light on the feasibility of implementation of POCT in primary care and on the views of practitioners about the use of influenza POCT in primary care, including its impact on primary care workflows.

Authors: Qi Jipeng , Zhang Kaiyuan , Fu Xiangfei , Zhao Xiaofang , Wang Ling
Published: March 2019

Although scholars have implied that relational factors motivate individuals to change the work environment and further craft their jobs, to date, few studies have been conducted to examine the relationships between these variables. Drawing on a person–environment fit perspective,
we examined the interactive effects of leader–member exchange (LMX), internal social capital, and thriving on job crafting. We used an online survey to collect data from employees (N = 212). Results showed that LMX was significantly related to job crafting. Internal social capital
moderated the relationship between LMX and job crafting. There was a 3-way interactive effect of LMX, internal social capital, and thriving on job crafting. The results constructed a person–environment fit perspective of job crafting. Our findings will help managers promote job crafting
by creating a suitable environment for practice.

Perencanaan Perencanaan produksi merupakan suatu kegiatan yang harus dilakukan sebelum proses produksi dimulai. Perencanaan produksi tidak hanya menyangkut mengenai apa yang diproduksi, melainkan ada beberapa hal yang harus dilakukan. Salah satunya merencanakan kebutuhan bahan untuk produksi. PT. X merupakan perusahaan yang bergerak pada bidang aksesoris otomotif. Dalam proses produksinya, PT. X mengalami kesulitan dalam pengendalian stok bahan baku karena stok bahan yang berlebih. Pemesanan kepada pemasok dilakukan tanpa adanya analisa yang akurat. Untuk itu PT. X memerlukan metode analisa penghitungan kebutuhan bahan sebelum proses produksi dimulai. metode yang dilakukan yaitu MRP (material requirement planning). Penelitian ini dilakukan dengan menentukan Jadwal Induk Produksi (JIP). Kemudian menentukan struktur produk stok bahan baku yang diperlukan untuk membuat satu produk jadi. Melakukan konversi dari jumlah Jadwal Induk Produksi (JIP) menjadi “kebutuhan bersih”. Selanjutnya membandingkan kebutuhan yang ada dengan jumlah stok yang ada. Dan menghasilkan informasi mengenai kapan dan berapa jumlah stok bahan yang harus dipesan kepada pemasok. Untuk mempermudah penghitungan, maka dibuat aplikasi berbasis web yang memiliki fungsi dalam melakukan peramalan stok dengan metode MRP. Hasil dari aplikasi MRP pada PT.X  adalah menurunnya jumlah stok bahan di gudang mencapai 50%.
Generalised stacking fault energies of copper alloys - density functional theory calculations
Authors: Muzyk M. , Kurzydłowski K.J.
Published: March 2019

Generalised stacking fault energies of copper alloys have been calculated using density functional theory. Stacking fault energy of copper alloys is correlated with the d?electrons number of transition metal alloying element. The tendency to twiningis also modified by the presence of alloying element in the deformation plane. The results suggest that Cu ?transition metal alloys with such elements as Cr, Mo, W, Mn, Re are expected to exhibit great work hardening rate due to the tendency to emission of the partial dislocations.

Authors: Botsford Keyan P. , Frazier Michael C. , Ghoneima Ahmed A. M. , Utreja Achint , Bhamidipalli Surya S. , Stewart Kelton T.
Published: March 2019

Objectives:

To evaluate the precision of the virtual occlusal record using the Carestream CS3600 Intraoral Scanner (Carestream Dental, Atlanta, Ga).

Materials and Methods:

A total of 20 participants were recruited for this prospective study using preestablished inclusion/exclusion criteria. A complete intraoral scan and two bite registrations were obtained. The participants were instructed to bite with normal pressure when bite registrations were acquired. Contact locations, size (circumference), and intensity were identified on the maxillary first molars and canines. Agreement between contact size and intensity was assessed with intraclass correlation coefficients. Kappa statistics evaluated agreement in contact locations. Statistical significance was set at P < .05.

Results:

All participant data were included for statistical analysis. Between the two bite registrations, nonstatistically significant differences were observed in the proportion of locations with contacts (P = .7681). A nonstatistically significant difference (−0.25 mm, P = .8416) in mean contact circumference size was observed. A statistically significant difference in mean contact intensity was observed (P = .0448). When evaluating agreement between the bite registrations, a weak correlation for size (intraclass correlation coefficient = 0.35) and intensity (intraclass correlation coefficient = 0.32) was observed as well as a moderate agreement for contact location (κ coefficient = 0.67).

Conclusions:

The findings suggest that the Carestream intraoral scanner software possesses adequate precision when acquiring the location and size of the contacts in bite registrations. The scanner failed to demonstrate adequate precision when acquiring contact intensities in bite registrations. Additional research is warranted to further investigate the precision of virtual occlusal records with currently available software systems.

Differentiating the World Picture and Worldview in Religious Education.
In the field of practical theology from a Christian pedagogical perspective we have to make a clear distinction between world picture (describing empirical reality) and worldview (determining personal affection to the first one). While the science based world picture tends to be as objective representation of our actual world as is could be, the worldview is hermeneutical system based upon principles, ideas and values. In most cases, mixing up these two notions cause tensions between faith and natural science. In order to clarify some points of differentiation and also reference to each other, this study investigates the two notions in the context of religious education.

Mujeres y redes internacionales. La Liga Paraguaya Pro Derechos de la Mujer (1951-1962) como parte de las disputas de la Guerra Fría
Authors: Soler Lorena
Published: March 2019

El artículo se inserta en la interacción problemática de la modernización política y las relaciones de género en el contexto de la Guerra Fría, para explicar las condiciones sociohistóricas que habilitaron el reconocimiento de los derechos políticos de las mujeres en Paraguay.Específicamente, se propone estudiar las formas asumidas parala conquista de la ciudadanía porun grupo de mujeresasuncenasorganizadas en la Liga Paraguaya Pro Derechos de la Mujer(1951-1962). Asume que dicha organización, a diferencia de otras experiencias que la precedieron, se inscribió en un movimiento internacional de reivindicación de la ciudadana que, en una coyuntura local de modernización excluyente impulsada por el orden stronista, pudo tejer una alianza con actores locales e internacionales que pregonaban un orden anticomunista.

Conceptualization and validation of organizational commitment
Authors: Ahn Jungwon , Lee Soonmook
Published: March 2019

We reviewed the key measurement and conceptualization problems of the Allen and Meyer's (1990) three-component model (TCM) of organizational commitment (OC), and established an unequivocal grounding of the OC concept which Korean workers perceive. To that end, we examined internal structures of OC construct and validated it in the context of workers in Korean domestic banks. Overall two studies were conducted with data collected from a sample of 519 full time workers of seven domestic banks in Korea. While affective (AC) and continuance commitment (CC) were measured using scales of the TCM as customized, normative commitment (NC) was measured using the six-item scale (Jaros, 2007) according to the researcher's hypotheses on conceptualization of OC. In study 1, measures of the 290 respondents were analyzed using exploratory structural equation modeling (ESEM). There were two phases scrutinizing factor structures of the OC scales. First, ESEM was conducted on the items of OC scale, and on the items measuring other constructs (assumed to be similar to OC or antecedents of OC). The result revealed that, contrary to our expectation, a unidimensional model of AC consisting of 10 items as indicators including six items of the AC construct and four items of the NC construct, fit the data best. In study 2, measures of the rest 229 respondents were analyzed using confirmatory factor analysis (CFA) to confirm the model developed in study 1. The result revealed that the unidimensional model of AC fit the data better than the other two-factor (AC, NC) and three-factor(AC, NC, CC) models. We concluded that the construct of OC for Korean bank workers, especially domestic bank officers can best be understood as a singular construct of affective dimension which is newly conceptualized and validated through the current study. Such a result was interpreted in light of the organizational cultural value orientations in Korean domestic banks. Implications for OC theory and its application were discussed concerning the present results.
The mediating effect of family-work enrichment in the influence of community embeddedness on turnover intention and work engagement
Authors: Sung HoKyoung , Yoo TaeYong
Published: March 2019

The purpose of this study was to examine the effect of community embeddedness, which is one of the subfactor of job embeddedness, on turnover intention and work engagement. Specifically, this study investigated the influence of community embeddedness on turnover intention and work engagement, and the mediating effect of family-work enrichment in these relationships. Self-reported survey data were obtained from 276 employees from various organizations in Korea. The results showed that community embeddedness and family-work enrichment were negatively related with turnover intention and positively related with work engagement. And community embeddedness was positively related with family-work enrichment. Finally, the relationship between community embeddedness and turnover intention, and the relationship between community embeddedness and work engagement were partially mediated by family-work enrichment. Implications, limitations of this study, and suggestions for the future research were discussed on the basis of the results.
The transformation from task conflict into relationship conflict

Published: March 2019

Task conflict influences organizational effectiveness differentially based on given contingencies. Effective conflict management is thus necessary in order to properly utilize task conflict in organizations. The present research was conducted to uncover buffer conditions, or moderators that diminish transformation effect of from task conflict into relationship conflict. Specifically, the researchers proposed (1) evaluation apprehension and (2) relational intimacy would buffer the transformation of task conflict into relationship conflict. In the first research, 269 employees participated in self-report survey. The results showed that the transformation of task conflict into relationship conflict more occurred in a evaluation apprehension situation than a non-evaluation apprehension situation and less occurred in a relational intimacy than a relational non-intimacy. The researchers then conducted an experiment on 88 undergraduate students. The results of the second research also indicated that the conflict transformation less occurred in non-evaluation apprehension condition and relational intimacy condition in consistence with study 1. Based on the results, theoretical and practical implications, research limitations and future research directions are discussed.

On the basis of Kress and van Leeuwen’s Visual Grammar based on Halliday’s Systemic Functional Linguistics, this study explores the interactive meaning in three public service advertisement multimodal discourses, adding evidence to the assumption that Systemic Functional Linguistics can be applied to the multimodal discourse analysis of public service advertisement in a feasible and operational manner.
Biomechanical comparison of a modified three-loop pulley technique and a three-level self-locking technique for repair of patellar tendon rupture in dogs
Authors: Soula Mariajesus , Shmalberg Justin W. , Johnson Matthew D.
Published: March 2019

OBJECTIVE

To compare use of a 3-level self-locking suture (3LSLS) technique with use of a previously described modified 3-loop pulley (M3LP) technique to repair rupture of the proximal aspect of patellar tendons in limbs from canine cadavers.

SAMPLE

Paired hind limbs of 6 adult mixed-breed dogs.

PROCEDURES

A limb from each pair was randomly assigned to be repaired by the 3LSLS technique or M3LP technique with size-2 ultrahigh-molecular-weight polyethylene and size-0 monofilament polypropylene suture, respectively. Limbs were prepared, and each patellar tendon was transected at a site chosen to simulate rupture at the proximal aspect. Tendons were repaired with the assigned techniques and mechanically tested with a biaxial servohydraulic test system; the clamp was distracted until the repair failed. Force at 1 -mm gap formation, 3-mm gap formation, and repair failure and gap size at failure were measured and compared between methods. Mode of failure was recorded.

RESULTS

There was no significant difference between methods for the force required to produce a 1 - or 3-mm gap in the repair. The 3LSLS technique required a significantly higher load for complete failure; gap formation immediately before failure was significantly greater for this method than for the M3LP technique. Four of 6 repairs with the M3LP technique and 0 of 6 repairs with the 3LSLS technique failed by suture breakage.

CONCLUSIONS AND CLINICAL RELEVANCE

The 3LSLS technique with size-2 ultrahigh-molecular-weight polyethylene suture was as effective at resistance to 1 - and 3-mm gap formation as the M3LP with size-0 monofilament polypropylene suture.
Single-day and multiday repeatability of stance analysis results for dogs with hind limb lameness
Authors: Wilson Megan L. , Roush James K. , Renberg Walter C.
Published: March 2019

OBJECTIVE

To assess single-day and multiday repeatability of weight distribution (stance) data obtained with a commercial analyzer for dogs with naturally occurring hind limb lameness.

ANIMALS

46 dogs (15 and 31 for single-day and multiday trials, respectively).

PROCEDURES

For single-day trials, 5 to 10 measurements/trial were collected to determine body weight (BW), weight distribution on each limb, and forelimb and hind limb symmetry indices (SIs). The dog was removed from the room and returned immediately; 5 trials were performed. For multiday trials, measurements were performed in the same manner on 2 sequential days. Data were compared among trials (single-day measurements) and between days (multiday measurements). Repeatability (correlation coefficients and Lin concordance correlation coefficients [LCCCs]) and variability (coefficients of variation [CVs]) were assessed.

RESULTS

In single-day trials, BW (r = 0.999), weight distribution on the lame hind limb (r = 0.915) and contralateral hind limb (r = 0.948), and hind limb SI (r = 0.964) were each significantly correlated among trials. In multiday trials, BW results were similar; weight distribution on the lame hind limb and contralateral hind limb and hind limb SI were each less closely but still significantly correlated between days. The LCCCs were highest for BW, weight distribution on the contralateral hind limb, and hind limb SI in single-day trials and for BW and weight bearing on the contralateral and lame hind limbs in multiday trials. The CVs were lowest for BW and highest for forelimb SI in both trial types.

CONCLUSIONS AND CLINICAL RELEVANCE

The analyzer used allowed repeatable measurement of BW and weight distribution on the hind limbs of dogs with hind limb lameness. Measurement of forelimb stance variables was not repeatable in this group of dogs.
The impact of cattle drinking points on aquatic macroinvertebrates in streams in south-east Ireland

Published: March 2019

Measures that prevent cattle access to watercourses are commonly implemented through agri-environment schemes, in an effort to address the objectives of the Water Framework Directive. Despite the widespread implementation, few studies have assessed the impact of cattle access to streams on aquatic macroinvertebrates. This study assessed the local-scale impact of cattle drinking points on water quality parameters (i.e. macroinvertebrate and water chemistry metrics) on 39 intensively-managed grassland farms in the south-east of Ireland. The results indicate that sites that were more than or equal to good quality upstream of cattle drinking points, were more susceptible to cattle access impacts than sites where upstream water quality was less than good. The European Court of Auditors (2011) recommended that there should be a higher rate of EU contribution for measures with higher environmental potential, in this instance, for cattle exclusion measures targeted to sites where background quality is more than or equal to good. Appropriate efforts should thus be made to incentivise farmers in good to high status sites to adopt cattle exclusion measures.
