Content and language integrated learning in Latin America 2008-2018: Ten years of research and practice
Authors: Banegas Dario Luis , Poole Paige Michael , Corrales Kathleen A.
Published: June 2020

Bilingual education, usually a community’s L1 and English continues spreading geographically and across educational systems worldwide. With this expansion, the development of bilingual education approaches is under constant scrutiny. One recent approach is content and language integrated learning (CLIL). European in origin, CLIL can be viewed as an educational or language teaching approach and it refers to the teaching of curricular content and L2 in an integrated manner. This approach has received international attention, yet, how CLIL unfolds in settings outside Europe appears underrepresented in international publications. The aim of this article is to provide a critical review of CLIL in Latin America between 2008 and 2018. We surveyed 64 items (articles, book chapters, and dissertations) published in regional and international outlets: 41 empirical studies, 19 practice-oriented publications, and four reviews. It begins by summarizing the CLIL continuum with a focus on content- and language-driven CLIL and CLIL frameworks. It then provides a synthesis of empirical studies and practice-oriented publications about CLIL in different Latin American settings. The corpus is analyzed following these unifying themes: pedagogy, perceptions and beliefs, teacher education, global citizenship, and language development. From this review, it transpires that Latin American CLIL is mostly implemented and examined from a language-driven perspective in private primary, secondary and higher education. Suggestions and implications for further research and practice are included.

Published: June 2020

Approximate Nearest Neighbor (ANN) search is a fundamental algorithmic problem, with numerous applications in many areas of computer science. In this work, we proposeindexable distance estimating codes (iDEC), a new solution framework to ANN that extends and improves the locality sensitive hashing (LSH) framework in a fundamental and systematic way. Empirically, an iDEC-based solution has a low index space complexity ofO(n) and can achieve a low average query time complexity of approximatelyO(logn). We show that our iDEC-based solutions for ANN in Hamming and edit distances outperform the respective state-of-the-art LSH-based solutions for both in-memory and external-memory processing. We also show that our iDEC-based in-memory ANN-H solution is more scalable than all existing solutions. We also discover deep connections between Error-Estimating Codes (EEC), LSH, and iDEC.
Efficient algorithms for budgeted influence maximization on massive social networks
Authors: Bian Song , Guo Qintian , Wang Sibo , Yu Jeffrey Xu
Published: June 2020

Given a social network
G
, a cost associated with each node, and a budget
B
, the
budgeted influence maximization (BIM)
problem aims to find a set
S
of nodes, denoted as the seed set, that maximizes the expected number of influenced users under the constraint that the total cost of the users in
S
is no larger than
B.
The current state-of-the-art practical solution for BIM problem provides a (1-1/
e
/2 --- ε)-approximate (≈ 0.316 --- ε) result and is still inefficient on large networks. We first show that we can improve the approximation guarantee to 1 --- 1/
e
β
--- ε where 1 --- 1/
e
β
= (1 --- β) (1 --- 1/
e
), achieving a better approximation guarantee (≈ 0.355 --- ε).

Next, we apply the reverse sampling based technique, a popular technique for classic influence maximization, to our studied BIM problem. However, it is non-trivial to design efficient solutions for large scale networks even the reverse sampling based technique is applied. On one hand, it is unclear how to derive tight bounds for the nodes selected by the greedy algorithm under the budgeted scenario, where each time it selects the seed node with the highest benefit-cost ratio. With tighter bounds, the algorithm can terminate as soon as the approximation ratio is satisfied, thus saving the running cost. On the other hand, the number of nodes selected under BIM problem may be quite large since it may greedily select many nodes with large benefit-cost ratio but with low costs. The time complexity of existing influence maximization algorithms heavily depends on the size of the seed set. To tackle such challenging issues, we first present new bound estimation techniques for the BIM problem. Next, we present new node selection strategies to alleviate the dependency to the size of the seed set. Extensive experiments show that our proposed solution is far more efficient than alternatives.

Functional Characterization of the Basal Amygdala-Dorsal BNST Pathway during Contextual Fear Conditioning
Authors: Sasaki Russell Jennifer , Trouche Stéphanie , Reijmers Leon G.
Published: June 2020

Both the basal amygdala (BA) and the bed nucleus of the stria terminalis (BNST) can participate in contextual fear, but it is unclear whether contextual fear engrams involve a direct interaction between these two brain regions. To determine whether dorsal BNST (dBNST)-projecting neurons in the BA participate in contextual fear engrams, we combined the TetTag mouse with a retrograde tracer to label dBNST-projecting cells in the BA. We identified a population of neurons located in the anterior subdivision of the BA (aBA) that was activated during fear conditioning and reactivated during retrieval but that did not project to the dBNST. In contrast, dBNST-projecting neurons located in the posterior BA (pBA) were activated during contextual fear conditioning but were not reactivated during retrieval. Similarly, we found neurons in the oval BNST subdivision (ovBNST) that were activated during contextual fear conditioning without being reactivated during retrieval. However, the anterodorsal BNST (adBNST) subdivision was not activated during either contextual fear conditioning or retrieval, underscoring the divergent functionality of these two dBNST subdivisions. Finally, we found that the ovBNST receives a monosynaptic projection from neurons located in the BA. Our results indicate that aBA neurons that do not project to the dBNST participate in contextual fear engrams. In contrast, dBNST-projecting neurons in the BA do not appear to participate in contextual fear engrams, but might instead contain a BA → ovBNST pathway that is active during the initial encoding of contextual fear memories.
Feminismos y género en los Estudios Internacionales
Authors: Grecco Gabriela de Lima
Published: June 2020

En las últimas décadas, el rol específico de las mujeres en las relaciones internacionales ha recibido más atención y las teorías feministas han ganado terreno en el debate intelectual, lo que ha contribuido a una sensibilización general hacia la incorporación del análisis de la categoría de género en la disciplina de las Relaciones Internacionales. De hecho, uno de los rasgos característicos de la disciplina había sido la invisibilización de las estructuras de género que impactan a hombres y mujeres de forma distinta. Sin embargo, con la irrupción del llamado “cuarto debate” se abrió una nueva oportunidad para pensar lo internacional desde miradas más críticas e inclusivas. El impacto de los estudios feministas tuvo lugar a finales de la década de 1980 con una publicación especial sobre género en la revista académica Millennium: Journal of International Studies. De gran relevancia en la actualidad son las teorías producidas fuera de los centros hegemónicos y que cuestionan tanto las teorías clásicas como el sistema de género occidental por encubrir un proyecto etnocéntrico. En efecto, las teóricas post y decoloniales pretenden desestabilizar los discursos hegemónicos sobre una supuesta experiencia universal de las mujeres. En este sentido, el objetivo central del presente artículo es realizar una revisión bibliográfica sobre las principales escuelas feministas, así como sistematizar la pluralidad de teorías y de prácticas feministas que han tenido lugar en el devenir de los estudios internacionales. De esta forma, tras una breve introducción sobre el surgimiento de los enfoques feministas en la disciplina, el presente estudio realiza un análisis de las aportaciones de las principales escuelas feministas: el feminismo liberal, el feminismo del punto de vista, el feminismo constructivista, el feminismo posmodernista, el feminismo postcolonial, el feminismo decolonial, la teoría queer y el enfoque sobre las masculinidades. A través del examen de estas diferentes corrientes teóricas, se analizará su impacto en la disciplina de las Relaciones Internacionales, evidenciando los cambios epistemológicos, metodológicos y ontológicos presentes en las diferentes escuelas. Las teorías feministas en las Relaciones Internacionales deben ser abordadas, pues, de manera multidimensional, en el sentido de reconocer las diferencias y elementos comunes respecto a las experiencias de las mujeres, hombres y disidentes sexuales desde diferentes latitudes.

Penyimpangan Penafsiran dalam Tafsīr Al-Tha’labī dan Al-Kashshāf Menurut Muḥammad Ḥusayn Al-Dhahabī
Authors: Saputra Ali Thaufan Dwi
Published: June 2020

This article reviews the conception of interpretation deviation according to Ḥusayn al-Dhahabī. According to him, many interpreters have certain motives for making deviations in interpreting the Qur’an. Broadly speaking, al-Dhahabī conceptualizes mis-interpretation into two things. First, the interpreters who tend to overtake Isrāiliyāt history excessively, this occurs in the tafsir bi al-ma’thūr. Second, interpreters who interpret verses with incorrect meanings, this happens in tafsir bi al-ra’yi. This second deviation is often done by mufasirs who have certain mazhab background and Sufis due to their use metaphorical language. The findings of this article are, al-Dhahabī considers that there are some deviations in the interpretation of the Quran in the book of al-Kashfu wa al-Bayān an Tafsīr al-Qur’ān by Abū Isḥāq Aḥmad ibn Ibrāhīm al-Tha’labī al-Naisaburī and al-Kashshāf ‘An Ḥaqā’iq Ghamāmi al-Tanzīl wa ‘Uyūn al-Aqawīl fī Wujūh al-Ta’wīl by Abū al-Qasīm Maḥmūd ibn ‘Umar Ibn Muḥammad Ibn ‘Umar al-Zamakhsharī. Some interpretations of al-Tha’labī are considered to be distorted due to a number of quotes from the history of Isrāiliyāt. On the other hand, some interpretations of al-Zamakhsharī are considered to be distorted because they distort the meaning and bias of the mazhab.

Clinical documentation is a fundamental component of the practice of medicine. It has significantly evolved over the past decade, largely because of the growth of health information technology and electronic health records. Although government agencies and other professional organizations have published position statements on the structure and use of electronic documentation, few have specifically addressed the documentation needs for the care of children. A policy statement on electronic documentation of clinical care by general pediatric and subspecialist providers by the American Academy of Pediatrics is needed. This statement provides insight on the unmet needs of key stakeholders to direct future research and development of the electronic media necessary to enhance the wellness of children and improve health care delivery. It also addresses the challenges and opportunities for efficient and effective clinical documentation in pediatrics.

Authors: Erdağı Kenan , Tüfekçi Osman , Yeşeri Mustafa , Yüksel Mehmet F. , Turgut Nimet , Eroğlu Burak E.
Published: June 2020

Background and Study Aim: Handgrip strength is widely accepted as a functionality parameter to assess upper extremity performance. The measurement of hand grip strength by dynamometry is a low cost, non-invasive method of simple applicability. The present study is based on the association of dominant and non-dominant handgrip strength with demographic and anthropometric characteristics; height, body weight, body mass index, upper arm length, forearm length, hand length, forearm circumference, upper arm circumference. Material and Methods: The study included 70 male athletes in olympic style weightlifting (age: 18.06±2.18, height:1.74±.06 m, body weight: 76.09±13.04 kg). A total of 70 sedentary individuals as a control group (age 18.11±.18, height:1.75±.04 m, body weight: 74.01±13.94 kg) were also taken to compare study findings. The data obtained was analyzed by SPPS for Windows, version 25. Handgrip strength measurements were obtained by a Jamar dynamometer, according to the recommendations of the American Association of Hand Therapists. Results: It was found that the values of dominant and non-dominant handgrip strength, upper arm circumference and forearm circumference length of the weightlifting athletes were higher than those of sedentary individuals (p<.001). No asymmetry was observed in dominant and non-dominant handgrip strength values of the athletes and sedentary individuals. The correlations were noted between dominant and non-dominant handgrip strength values of weightlifting athletes and demographic characteristics, some anthropometric characteristics of upper extremity and weightlifting performance. Conclusion: The variability of handgrip strength might largely be explained by some anthropometric characteristics of upper extremity.
Local Tradition and Harmony among Religious Adherents: the Dominant Culture of Hindu-Muslim Relation in Jembrana Bali
Authors: Saihu Saihu
Published: June 2020

This study discusses the harmony of Hindu-Muslim’s local traditions in Jembrana, western Bali. This anthropology study employs Bruner's dominant cultural theory approach to see the practice of harmony in local communities. This study focuses on several local Hindu-Muslim traditions in Jembrana, which reflect harmony among religious communities, namely the tradition of ngejot, makepung, male, and rebana (tambourine). The ethnographic study confirms the importance of respect for the dominant culture carried out by the Muslim minority when implementing their religious traditions. Although the tradition of male and rebana, for instance, are Islamic traditions, Balinese Muslims adapted to Balinese customs as the dominant culture. They understood their positions to maintain and respect the dominant Balinese culture performed by the majority of Hindus in Jembrana. Balinese Hindus tried to show an excellent response to the Muslims by involving them in the local Balinese tradition even with the adaptation of their rituals. It is a wealth of local tradition that shows religious harmony portrait in Indonesia.
Tahuri: Symbol of the Christian-Muslim Community Peace in Tehoru and Telutih, Central Maluku, Indonesia
Authors: Dandirwalu Resa , Rehy Handry Yance
Published: June 2020

This study departs from the social conflict in Maluku in 1999. The conflict separated the Christian and Muslim communities in Tehoru and Telutih Districts, Central Maluku, Indonesia. Then, the Regional Government of Central Maluku Regency reconciled by returning the Christian community to both Districts. However, the Christian community still felt anxious and insecure because peace is only carried out by the Government Agency. Both communities created Tahuri symbol as a peace symbol between them.  In 2014, they made Tahuri monument, and it was inaugurated on December 7, 2016. Therefore, the purpose of this study was to find the meaning of Tahuri symbol as peace of Christian and Muslim communities in  Tehoru and Telutih Districts. The focus of this study the peace symbol created by both communities of Tehoru and Telutih. This study employs Symbolic Anthropology to find the meaning of symbols accepted by humans through relations with others and their natural world. Data gathered through observation and interviews in both districts and presented using a descriptive analysis model. The result shows that Tahuri symbol has two important principles: the inclusive principle and mutual trust principle. Besides, for the Christian and Muslim communities, the Tahuri symbol means collective identity and social cohesion. Both communities contextualized these two principles and meanings in their social and religious life so that social and religious dynamics cannot reduce them. They live in harmony. The peace through the Tahuri symbol is maintained to this day.
Scientific approaches to the economic category «public sector efficiency»
Authors: Gersonskaya Irina
Published: June 2020

The article investigates scientific approaches to the category of «public sector efficiency» that have been formed in foreign and domestic economic theory. The author substantiates the necessity of functioning of the public sector system of the national economy and evaluating the effectiveness of its activities. The author considers the first points of view in the scientific world of the physiocrat F. Kene, as well as representatives of the school of classical political economy W. Petty and D. Ricardo in determining the performance of government structures. We study the works of the founders of the concepts of effective functioning of activities in the market economy, including state organizations, such as V. Pareto, A. Pigou, J.M. Keynes, P.F. Drucker, and others. Modern concepts of the efficiency of the public sector of the economy in Western economic theory, developed by
P.E. Samuelson, W.D. Nordhouse, R.A. Musgrave, J.E. Stiglitz, N.G. Mankyu, K.R. Mcconnell, and others. Analyzes the scientific approaches to evaluating the effectiveness of the public sector in the national economy domestic scientists-economists such as E.V. Balatsky, O.A. Kokorina,
T.D. Romashchenko, Yu.I. Treschevsky, V.V. Lukyanova, O.V. Rudakova, E.M. Samorodova,
A.V. Revkuts, S.R. Muravyov, etc. On the basis of analysis of scientific works the author has selected a targeted, cost management and production approaches to the evaluation of the effectiveness of the public sector. In the course of the study, it was concluded that evaluating the performance of the public sector of the national economy based on only two aspects is not appropriate, since it does not fully reflect the activities of all structural components of the public sector. The author believes that the structure of the public sector of the economy includes three main, specific and quite independent elements-management structures, state corporations and the «social sector of the state». Therefore, it is advisable to conduct a study of the efficiency of activity of the public sector of the national economy using a three-component indicator that reflects all areas of activity and aspects of its functioning.

ABSTRACT Background: The congenital Zika syndrome involves structural brain changes, including ventriculomegaly, thin cerebral cortices, abnormal gyral pattern, cortical malformations, hypoplasia of the corpus callosum, myelination delay, subcortical diffuse calcifications, brainstem hypoplasia, and microcephaly in newborns. Objective: This study aimed to describe the clinical characteristics of children with congenital Zika syndrome; to compare the outcomes of infants infected in the first (1T, n=20) and second trimesters of pregnancy (2T, n=11); to investigate correlations between birth weight, birth and follow-up head circumference, birth gestational age, and gross motor scores. Methods: Participants were evaluated with Alberta Infant Motor Scale (AIMS) and part A of the Gross Motor Function Measure (GMFM-A). ANOVA compared head circumference, birth gestational age, birth weight, and gross motor performance of 1T and 2T. Results: The correlations were investigated by Pearson correlation coefficients. ANOVA showed differences in birth and follow-up head circumferences. Head circumference was smaller in 1T, compared to 2T. Motor performance was classified as below the fifth percentile in AIMS in all children and 1T showed lower scores in prone, sitting, and total AIMS score, compared to 2T. Children ranged from 8 to 78% on GMFM-A and there was a poorer motor performance of 1T. Nineteen children showed hypertonia, six showed normal tone and six showed hypotonia. Birth head circumference was correlated with AIMS prone postural control. Follow-up head circumference was correlated to prone, supine and total AIMS scores. Smaller head circumference at birth and follow-up denoted poorer postural control. Discussion: Children with congenital Zika syndrome showed microcephaly at birth and follow-up. Smaller head circumferences and poorer motor outcomes were observed in 1T. Infants showed poor visual and motor outcomes. Moderate positive correlations between birth and follow-up head circumference and gross motor function were found.

Authors: VITTURI Bruno Kusznir , GAGLIARDI Rubens José
Published: June 2020

ABSTRACT Background: Statin therapy has become one of the most important advances in stroke secondary prevention. Objective: To provide evidence from real-world data for evaluating detailed associations between secondary prevention of stroke and statin use in Brazil. Methods: We conducted a prospective cohort study including consecutive patients diagnosed with an ischemic stroke. Subjects were classified into non-statin, simvastatin 20 mg, simvastatin 40 mg, and high-potency statin groups. We also registered the onset of statin therapy, previous use of statins, the adherence to medication, and if there was discontinuation of the therapy. After two years, the functional outcome, stroke recurrence, major cardiovascular events, and mortality were assessed. Results: Among the 513 patients included in our cohort, there were 96 (18.7%) patients without statins, 169 (32.9%) with simvastatin 20 mg, 202 (39.3%) with simvastatin 40 mg, and 46 (9.0%) with high-potency statins. Patients without statins were at increased risk of stroke recurrence and worse functional outcomes. Concerning etiology, evidence of beneficial use of statins was observed in cases of large-artery atherosclerosis, small-vessel occlusion, and stroke of undetermined cause. Those who presented poor adherence to statins or discontinuation of the treatment had worse prognosis after stroke whereas the early onset of statins use was associated with better outcomes. Patients with simvastatin 40 mg and high-potency statins presented the best functional recovery throughout the follow-up. Conclusions: Statins play an important role in the treatment of ischemic stroke, preventing stroke recurrence and cardiovascular events, and improving functional performance.

ABSTRACT Background: Central nervous system changes associated to systemic arterial hypertension (SAH) are progressive and may cause negative effects on cognitive performance. The objective of this study was to investigate the relation between SAH and the components of executive functions (EF), inhibitory control (IC), updating and shifting, comparing a control group (without SAH) to patients with SAH, in two levels of severity. Methods: The protocol included the following tests to evaluate EF components: T.O.V.A. Test (IC), Backward Digit Span from Wechsler Adults Intelligence Scale (WAIS-III), Phonemic and Semantic Verbal Fluency (updating), and Trail Making Test Part B (shifting). Results: A total of 204 participants was included: 56 from the Control Group (CG), 87 SAH stage 1, and 61 SAH stage 2. The groups were not different for age (52.37±12.29) and education (10.98±4.06). As to controlled blood pressure (BP), duration of hypertension treatment and number of drugs, the SAH 2 group had a worse BP control, longer duration of hypertension treatment and use of more drugs when compared to the SAH 1. The findings revealed that patients with more severe hypertension presented worse performance in updating (Backward Digit Span, phonemic and semantics VF) and shifting (Trail Making Test Part B). Conclusion: The results suggest that patients with SAH have a significant impairment in EF, more specifically in updating and shifting. Besides that, such damage may be directly proportional to the severity of SAH. It is suggested that future studies include neuroimaging exams to exclude possible cerebrovascular diseases.

Authors: Calderaro Douglas Rhoden , Lacerda Daniel Pacheco , Veit Douglas Rafael
Published: June 2020

Abstract: Additive Manufacturing (AM) has seen continued growth in adoption by organizations in recent years, changing production processes, supply chain, maintenance, product development and the global economy. There are several Additive Manufacturing technologies and equipment on the market, however, there are no guidelines, benchmarking or decision support tools for proper selection. After a systematic review of the literature, the lack of propositions that act during the development of the product and process was evidenced. This research focuses on the selection of Additive Manufacturing technologies for a production system. The general objective being to propose a decision support model based on the characteristics of additive technologies and competitive criteria, resulting in a choice aligned with the guidelines of organizations and their production systems. For the operationalization of the model, the AHP techniques and conjoint analysis were used together, where the characteristics of the Additive Manufacturing technologies were related to the competitive criteria for the model to indicate the recommended technology to the production system or organization in question. Finally, the artifact recommended the right technology in three distinct situations, from a vendor, user, and expert point of view. Thus, this research contributes to both academia and business by developing a functional artifact of additive manufacturing technology selection. Also, by contributing to the increased availability of information on the nine most commonly used additive technologies in industry.
Application of Automation and Manufacture techniques oriented to a service-based business using the Internet of Things (IoT) and Industry 4.0 concepts. Case study: Smart Hospital
Authors: Flórez Camilo Andrés Cáceres , Rosário João Mauricio , Hurtado Dario Amaya
Published: June 2020

Abstract: The implementation of Manufacture and Automation techniques is mandatory in the current world. Mainly, the enhancement and progress of healthcare are fundamental in wellbeing improvement. This paper points to the utilization of the Internet of Things (IoT) and Industry 4.0 concepts oriented to the optimization of a Smart Hospital using the Hospital Emergency Department (HED) as a case study. This proposal focuses on the development of a smart Hospital-based of the IoT, Industry 4.0, Health 4.0, and other current technology. On the other hand, the use of a computational simulation tool like the Discrete Event Simulation Model (DES) will allow the test, recognition, and reduction of bottlenecks in the HED workflow. The issue given by the bottlenecks is automatically controlled using an improved dynamic shift management proposal based on control theory, forecasting methods, and telemedicine. The results show an improvement in the use of the resources and a reduction of the length of stay that directly reduces the HED mortality rate, improving the service quality. The objective of this paper is to propose a simulation tool-based on DES for a selected HED, using forecasting methods of the patients’ arrival in a HED using the Autoregressive integrated moving average (ARIMA) model. Following the forecasted entries, a proposal for bottleneck avoidance using a HED DES was realized. The forecasting data provided useful predictive information for the improvement of the HED workflow. As well as the analyzed data of a traditional HED system is helpful to solve the overcrowding problem. Finally, the use of simulation tools allows the test and validation of novel proposals for two smart HED optimization proposals following e-Health and Hospital 4.0 principles.
Automated risk assessment for material movement in manufacturing
Authors: Pradhan Ninad , Balasubramanian Prashanth , Sawhney Rupy , Khan Mohammad Hashir
Published: June 2020

Abstract: Proximity movements between vehicles transporting materials in manufacturing plants, or “interfaces”, result in occupational injuries and fatalities. Risk assessment for interfaces is currently limited to techniques such as safety audits, originally designed for static environments. A data-driven alternative for dynamic environments is desirable to quantify interface risks and to enable the development of effective countermeasures. We present a method to estimate the Risk Prioritization Number (RPN) for mobile vehicle interfaces in manufacturing environments, based on the Probability-Severity-Detectability (PSD) formulation. The highlight of the method is the estimation of the probability of occurrence (P) of vehicle interfaces using machine learning and computer vision techniques. A PCA-based sparse feature vector for machine learning characterizes vehicle geometry from a top-down perspective. Supervised classification on sparse feature vectors using Support Vector Machines (SVMs) is employed to detect vehicles. Computer vision techniques are used for position tracking to identify interfaces and to calculate their probability of occurrence (P). This leads to an automated calculation of RPN based on the PSD formulation. Experimental data is collected in the laboratory using a sample work area layout and scale versions of vehicles. Vehicle interfaces and movements were physically simulated to train and test the machine learning model. The performance of the automated system is compared with human annotation to validate the approach.
Highlighting the benefits of Industry 4.0 for production: an agent-based simulation approach
Authors: Cavata Julio Takashi , Massote Alexandre Augusto , Maia Rodrigo Filev , Lima Fábio
Published: June 2020

Abstract: Advanced Manufacturing or Industry 4.0 concepts bring new advances and challenges to current industrial processes. Such concepts are not always well understood and their results in terms of production performance may not be clear. This work proposes a comparison between a traditional manufacturing process and an advanced manufacturing process, both modelled by a multiagent society. In the traditional manufacturing simulation, the agents follow the defined times of each process, including the maintenance times. In the advanced manufacturing simulation, the decision about when to stop a piece of equipment for maintenance is defined by the agent according to data received from sensors and the definitions of the process. The results indicate a significant improvement in equipment usage and consequently higher production in the same time interval. The process simulation clearly indicates that the application of advanced manufacturing concepts in industry is relevant in order to increase the efficiency of production processes. Among the main concepts introduced in advanced manufacturing models are the Internet of Things (IoT), Cyber-Physical Systems (CPSs), and Artificial Intelligence (AI). The models generated are computationally simulated using an agent-based simulation method from the software AnyLogic. The results obtained should contribute to encouraging small and medium sized enterprises to adopt the concepts of Industry 4.0 in their businesses.

ABSTRACT The objective of this study was to evaluate the effects of acidity and availability of micronutrients on a sandy clay loam Oxisol grown with soybeans (summer) and black oat (autumn/winter), after long-term applications of biodigested sewage sludge (BS) and centrifuged sewage sludge (CS). The experiment was conducted in Botucatu, SP, Brazil, from 2002 to 2014, using a randomized block design, in 2×4 factorial scheme, with four repetitions. Treatments corresponded to six biennial applications of BS and CS at four doses: 0, 2, 4 and 8 Mg ha-1 (dry basis). Soil samples up to 0.60 m depth were taken after twelve years, and pH, potential acidity, exchangeable acidity and micronutrient contents were evaluated. The CS applications of 4 and 8 Mg ha-1 led to pH values within the recommended range up to depths of 0.10 and 0.20 m, respectively, whereas BS applications did not result in adequate pH values in any layer. The increased soil pH caused by CS applications resulted in a proportional reduction in soil potential acidity, whereas BS applications resulted in high value of potential acidity (70 mmolc dm-3) in all layers. The CS applications resulted in low Al3+ concentrations up to 0.20 m depth, whereas BS applications led to high Al3+ concentrations from the 0.05-0.10 m layer. The successive applications of both sludges resulted in Cu2+, Fe2+, Mn2+ and Zn2+ concentrations that exceeded the maximum values allowed in all soil layers.

Resumo: Introdução: A empatia envolve a capacidade de identificar e perceber os sentimentos e as experiências pessoais do paciente, assim como a capacidade de ver o mundo da perspectiva de outra pessoa. Em pediatria, existe o desafio de buscar o bom relacionamento com o paciente pediátrico e seus acompanhantes, os quais são peças fundamentais no atendimento e no resultado do tratamento. O objetivo desse estudo foi avaliar o nível de empatia dos estudantes de Medicina em relação ao paciente pediátrico. Método: Trata-se de estudo transversal, com amostra de conveniência, realizado com estudantes do quarto e sexto anos do curso de Medicina da Universidade José do Rosário Vellano, Campus Alfenas. Os níveis de empatia foram avaliados por meio da Escala de Empatia de Jefferson. Questionário sociodemográfico coletou dados sobre as possíveis variáveis independentes, como sexo, idade, estado civil, doença crônica pessoal ou familiar, distúrbio mental, especialidade pretendida, entre outros. Utilizaram-se o teste de t de Student, o teste exato de Fischer bicaudal e a regressão linear. O nível de significância foi de 0,05. Resultados: No período de fevereiro a abril de 2019, dos 196 estudantes elegíveis para o estudo, 159 concordaram em participar. Desses, 10 (6,2%) foram excluídos por preenchimento incompleto do questionário. A amostra final foi de 149 (76,0%) estudantes, sendo 74 (49,7%) do quarto ano e 75 (50,3%) do sexto ano do curso de Medicina. Não houve diferença entre o escore global de empatia entre o quarto e o sexto ano. O escore global de empatia foi maior no sexo feminino (pajustado = 0,011), assim como o escore do domínio “cuidado compassivo” (pajustado = 0,013). Os voluntários com relato de doença crônica familiar e os que tinham dificuldade de realizar exame físico pediátrico apresentaram escore significativamente mais elevado no domínio “cuidado compassivo” (pajustado = 0,038 e pajustado = 0,037, respectivamente). Conclusões: Os níveis de empatia (escore global e diferentes domínios) observados neste estudo foram elevados, com exceção do domínio “capacidade de se colocar no lugar do outro”. Não se observou relação entre escore global de empatia e seus diferentes domínios e o ano do curso médico.

Resumo A dinâmica ambiental contemporânea tem influenciado a adoção de níveis de análise mais abrangentes para a compreensão de fenômenos organizacionais. Temas como formação de redes, alianças integração entre público e privado e outros desenhos organizacionais mais complexos exigem estudos que vão além do escopo interno das organizações. Dentre as questões de interesse desse campo de investigação, a confiança tem recebido grande atenção de pesquisadores no mundo inteiro, dada a sua importância para a adoção de mecanismos de governança mais flexíveis e adaptativos. o presente trabalho objetiva apresentar algumas definições de confiança e quatro das principais correntes teóricas que se propõem a compreendê-la enquanto fenômeno social - escolha racional, custos transacionais, neo-institucionalismo e a teoria do sistema social - destacando seus pressupostos centrais e as contribuições almejadas, orientadas pela dinâmica das relações interorganizacionais.
Caracterização do público lojista de um centro de compras no agreste das confecções: tendências disposicionais e tensões administrativas

Published: June 2020

Resumo Este artigo visa avançar no sentido de caracterizar o público lojista, proprietários de negócios e gerentes/responsáveis de um centro de compras situado em uma região específica do interior do Nordeste brasileiro. Por meio de uma leitura contextualizada da noção de habitus (Bourdieu), toma como objetivos específicos: (1) explorar similaridades e diferenças, em termos de tendências disposicionais administrativas, no referido público; e (2) identificar possíveis focos disposicionais para a tensão existente entre tal público e a administração do empreendimento. Trata-se de um estudo exploratório, em que foram aplicados 159 questionários e realizadas observações de campo de inspiração etnográfica. Acredita-se que a elaboração de uma ferramenta teórica própria (a noção de tendências disposicionais administrativas) para caracterizar esse tipo de público, nesse tipo de contexto, seja algo que pode contribuir para o conhecimento de fenômenos dessa natureza (objeto dos estudos organizacionais) e, desse modo, servir de inspiração a demais estudos no campo. Os resultados identificaram três tendências disposicionais administrativas que parecem ser significativamente recorrentes entre os pesquisados, a saber: (1) manutenção de práticas próximas à administração-feirante; (2) adaptação ao novo ambiente de negócios; e (3) hibridismos administrativos.
Entre posse e acesso: compreendendo a extensão do self no consumo colaborativo

Resumo A pesquisa busca compreender como se dá a extensão do self na prática do consumo colaborativo por meio do sistema de compartilhamento de bicicletas de Pernambuco. O estudo é alicerçado em abordagem qualitativa, com dados coletados por observação participante nas plataformas do Bike PE e entrevistas individuais não estruturadas com 24 usuários do projeto. Os dados foram interpretados a partir da aplicação da análise de discurso social-hermenêutica. Verificou-se que a possibilidade de pedalar pelo Bike PE representa uma oportunidade para reafirmar e construir certos elementos identitários ligados especialmente ao social e ao coletivo que estimulam ações conjuntas e/ou interativas. Assim, a identidade na prática colaborativa dos usuários do Bike PE é desenvolvida e estendida a partir do self relacional e do self influenciador e idealista. Identificou-se ainda que alguns usuários são também proprietários de bicicletas, apontando que o consumidor está disposto a experimentar novos modelos de prestação de serviços sem abandonar antigas práticas de consumo, como a aquisição de um bem. Com uma identidade multifacetada, os indivíduos buscam possibilidades de extensão e construção do self por meio do acesso e da posse, sendo a utilização do produto o elemento central na construção e extensão identitária, independentemente de o objeto usado ser próprio ou não.

THE SCHOOL CURRICULUM: A CULTURAL HISTORY VIEWPOINT AND THE MODERNIZATION OF THE ARITHMETICS TEACHING IN PARANÁ’S STATE PRIMARY SCHOOLS IN THE EARLY XXTH CENTURY
Authors: Pinto Neuza Bertoni
Published: June 2020

ABSTRACT From the viewpoint of cultural history, this paper analyzes disputes about purposes and methods for teaching arithmetic’s in Paraná’s state primary schools, as published in the magazine A Escola (The School) in the early XXth century. It highlights behind-the-scenes speeches by intellectuals who advocated a laic and free primary education, in which the main issue, besides of the pedagogical order, was also social and political, an aspect generally absent in the curriculum guidelines.

Abstract: The objective of this work was to evaluate the root system of Conilon coffee (Coffea canephora) and Arabica coffee (Coffea arabica) plants in the soil profile, using semivariograms. The evaluations were carried out in an area located in the municipality of Jaguaré, in the state of Espírito Santo, Brazil. The Verdebrás G30/G35 Conilon coffee and the Catuaí Vermelho IAC 44 Arabica coffee cultivars were assessed. Soil monoliths with coffee plant roots were collected at three distances from the trunk in the planting row and at six distances from the trunk between rows, at six depths. The roots were collected and washed and then digitized and processed in the Safira software. The spatial variability of the evaluated attributes was characterized by the geostatistical technique, through semivariograms, using the GS+ 7.0 software. Root surface area, length, and volume were quantified for the two coffee species. Conilon coffee plants have a tendency of showing a root system with a smaller surface area, shorter length, and lower volume by volume of soil, as well as a less discrepant distribution on soil surface and in deeper layers, compared with Arabica coffee.
People Do Not Just Plan,They Plan to Plan

Planning is useful. It lets people take actions that have desirable long-term consequences. But, planning is hard. It requires thinking about consequences, which consumes limited computational and cognitive resources. Thus, people should plan their actions, but they should also be smart about how they deploy resources used for planning their actions. Put another way, people should also “plan their plans”. Here, we formulate this aspect of planning as a meta-reasoning problem and formalize it in terms of a recursive Bellman objective that incorporates both task rewards and information-theoretic planning costs. Our account makes quantitative predictions about how people should plan and meta-plan as a function of the overall structure of a task, which we test in two experiments with human participants. We find that people's reaction times reflect a planned use of information processing, consistent with our account. This formulation of planning to plan provides new insight into the function of hierarchical planning, state abstraction, and cognitive control in both humans and machines.
