Measuring pre-service teachers’ general pedagogical knowledge—What are the results telling?
Authors: Malva Liina , Leijen Ali , Baucal Aleksandar
Published: May 2019

A pilot study was carried out in order to attempt capturing teachers' general pedagogical knowledge (GPK). The aim of the paper is to find out how pre-service teachers' GPK differs within internship experience, level of education and work experiences, and what can be concluded about the test instrument based on results. All together 135 pre-service teachers from Estonia filled in a knowledge test with 60 multiple choice questions. The results showed that those who had not done their internship performed better at the test, possibly indicating a theoretical nature of the test instrument. However, it also shows a shift in pre-service teachers' knowledge when entering practical field. Therefore, it can be discussed whether the experiences from practice schools differ from what has been learned at the university courses. For future test developments, the theoretical inclination of the test should be challenged by improving items targeting more of practical knowledge.

The integration of ICT in educational process in IB education - A comparative case study
Authors: Pantzos Panagiotis
Published: May 2019

This study aims to gain a deep understanding of international baccalaureate (IB) primary years programme (PYP) teachers' perceptions about the use of information and communication technology (ICT) in IB PYP classes. Moreover, it seeks to critically identify the teachers' barriers and needs in order to integrate ICT into teaching and learning. Following a qualitative comparative case study research design, semi-structured interviews were conducted with IB PYP teachers and coordinators in Sweden and Greece. Critical theory, critical pedagogy and critical theory of technology (CTT) were used as the theoretical framework for analysing teachers' perceptions. From a critical point of view, the study reveals that deskilling of teachers, intensification of teachers' work, low school's financial budget, parents' financial burden, commodification and privatisation of IB education are the fundamental factors that negatively intervene in teachers' work in both schools and perpetuate the status quo of teaching and learning processes through integration of ICT.
Keywords: International baccalaureate (IB), international and comparative education (ICE), integration of ICT, critical pedagogy, critical theory of technology (CTT).

Published: May 2019

The current paper analyses two different statistical techniques: i.e., principal components analysis (PCA) and correspondence analysis (L' analysee factorielle des correspondances) (AFC). A survey was carried out using a structured questionnaire for a sample of 135 nurses which studied in the School of Pedagogical and Technological Education (ASPETE) in Greece. Tangibility, Reliability, Responsiveness, Assurance, Empathy and Associability subscales are related to Qualitative Services ASPETE offers. These subscales were measured by 24 items, rated on a seven-point Likert scale. The study focuses on the presentation of the two main types of clustering methods, PCA and AFC. Lee and Lina's model contains a one-item scale developed to measure overall service quality and a one-item scale for customer satisfaction. The assessment of the students' satisfaction degree is evaluated based on a seven-step on the Likert scale statement, investigating the extent that the respondents are satisfied from the experience they had with the specific tertiary education organisation (CSF).

The cognitive problems influence on food disorders
Authors: Calin Mariana Floricica , Grigore Marinela Carmen
Published: May 2019

Nutritional disorders describe restrictive and/or abusive behaviours that affect both women and men alike. The relationship with food can change in the sense of food preferences, sometimes eating healthier, and sometimes not, or eating more or losing appetite. An eating disorder is a mental disorder defined by abnormal eating habits that adversely affect a personâ€™s physical or mental health. The cause of eating disorders is not clear. We aim to identify whether there is a correlation between personality traits and feeding disorders in young adults aged 20â€“25 years. To verify the work hypothesis, we applied the MCMI Personality Tracking and EDI 3 Test for Food Disorder on a 150-person group of participants aged 20â€“25 years. The media plays a major role in the way people see themselves. And, socio-economic status is a factor that influences eating disorders.

Published: May 2019

The quality of education is one of the major challenges facing many countries in the world, and Morocco is strongly concerned. Health and education in the Kingdom remain the sectors that suffer the most, and where there are many dysfunctions. Since Independence, the Moroccan education system has been subject to several reforms, involving a considerable amount of work and money spent without finding the right formula. From Arabisation to the emergency plan 2009â€“2012, passing through a large number of successive proposals, wiping failure after failure in the absence of a rigorous plan. As a result, the entire school and university system today suffers from structural problems.

Investigation of students' perceptions of national identity
Authors: Gelisli Yucel , Kazykhankyzy Lazura
Published: May 2019

The concept of identity is described as a set of characteristics that an individual or a group of individuals possess and what makes them unique and different from others. In other words, identity is about culture, social life, traditions and customs as well as attitude, perception and a belief system of people. The identity which is unique to a particular nation and brings together individuals with feelings of belonging to a particular community is called a national identity. National identity is the expression of belonging to a national culture. The National Identity Perception Scale developed by Gelisli was used to collect the data. Descriptive analyses (mean and standard deviation), Mann - Whitney U test and Kruskal - Wallis H test were performed to analyse the data. The results revealed that secondary and high school students possessed a high level of national identity. Moreover, it was found that gender influenced the students' perceptions of national identity.

The profile of the Brazilian over indebted consumer in the economic crisis worsening: A comparative analysis 2014-2016
Authors: Carvalho Rafaela Nogueira , Sampaio Patrícia Regina
Published: May 2019

Over-indebtedness is a phenomenon observed nowadays in both developed and developing countries, such as Brazil. In 2014, after analyzing data from a national survey, Sampaio and Porto presented some characteristics of the profile of over-indebted individuals in Brazil based upon self-declaration. Their analysis found that most overindebted individuals were women, with an average income of 1 to 2 minimum wages, aged between 25 and 44, and corresponding level of education to be complete high school. Data were also consistent with the international literature in the sense that isolated events such as unemployment, illness, marriage, birth of children and divorce, which often appear as being positively correlated with overindebtedness, were quoted in the survey, with emphasis in unemployment. This paper investigates the hypothesis that the profile of Brazilian over-indebted individuals may have changed due to the economic crisis. The alternative hypothesis is that the above characteristics have remained constant despite the deterioration of macroeconomic conditions. This analysis, if conclusive, may be relevant to the long-term planning of public policies to prevent and treat the phenomenon of overindebtedness. This work deepens the analysis of the over-indebted profile by testing the same hypothesis for the subgroup of individuals who claimed to be experiencing great difficulty in paying their debts (“heavy burden”), without, however, formally self-declaring to be overindebted
Developmental Social Work in Disability Issues
Authors: Higashida Masateru
Published: May 2019

(This is a full colour version.) In this ambitious book composed of the author’s published articles, he develops practical and theoretical frameworks for social work in disability issues. He explores practical strategies for promoting social and economic participation of disabled people from the perspective of developmental social work, whilst examining the situation of their socioeconomic participation in rural Sri Lanka. Based on these theoretical and practical frameworks, together with policy analysis of community-based rehabilitation (CBR), the field research was undertaken collaboratively with local stakeholders in three districts. The findings suggest that developmental social work practices, including an indigenous approach, social investment, and a multi-sectoral approach, could address the vicious cycle of inadequate education, poverty, and marginalisation. This book also explores the implications of these findings for policy and practice in other contexts.

Published: May 2019

The removal of Pb(II) ions from synthetic wastewater using Delonix regia pods and leaves as low-cost biosorbents was investigated. The elemental, morphological and phase characterization of Delonix regia pods and leaves were examined before and after biosorption. The adsorption process at various pH values, contact times, initial concentration of Pb(II) ions and adsorbent doses was studied with the aim of investigating the consequences of these parameters on the process of biosorption. The Langmuir adsorption isotherm provided the best fit for the experimental data of the pods while the Freundlich isotherm gave a better fit for the leaves of Delonix regia. The optimum adsorption capacity of 30.27 mg/g for the pods and 27.60 mg/g for the leaves was achieved when 0.5 g of the adsorbent was mixed with 20 mL of 1,000 mg/L Pb(II) ions solution for 30 min at 21 ± 2 °C and a stirring speed of 18 rpm. The data obtained from the time-dependent experiment of the biosorbents followed the pseudo-second-order kinetic model. This study showed that Delonix regia pods and leaves could be developed further as a low-cost sorbent that could be harnessed for removing Pb from industrial wastewater and thus limit water pollution from point sources.
FeNiCeOx ternary catalyst prepared by ultrasonic impregnation method for diclofenac removal in Fenton-like system
Authors: Xian Guang , Zhang Nan , Zhang Guangming , Zhang Yi , Zou Zhiguo
Published: May 2019

FeNiCeOx was firstly prepared by ultrasonic impregnation method and used to remove diclofenac in a Fenton-like system. The catalytic activity was improved successfully by doping Ni into FeCeOx. The diclofenac removal efficiency reached 97.9% after 30 min reaction. The surface morphology and properties of FeNiCeOx were characterized by Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Raman and X-ray photoelectron spectroscopy (XPS) analyses. FeNiCeOx in this paper had larger specific surface area than those prepared by other methods, which was attributed to the cavitation effect and hot-spot effect during the ultrasonic synthesis process. Low crystallinity of Fe2O3 and NiO showed by characterization could lead to high interaction of Fe and Ni ions with support of CeO2. They substituted Ce in CeO2, caused lattice contraction and formed more oxygen vacancies, which favoured the catalytic reaction. Meanwhile, Fe and Ce ions both had redox cycles of Fe3+/Fe2+ and Ce4+/Ce3+, which facilitated the electron transfer in the reaction. The synergistic effect among Fe, Ni and Ce might lead to better catalytic performance of FeNiCeOx than any binary metal oxides constituted from the above three elements. Finally, the potential mechanism of diclofenac removal in FeNiCeOx-H2O2 system is proposed.
ABOUT INVARIANCE OF ANGLE NOISE DISTRIBUTION PARAMETERS BY AN ARBITRARY N-POINT GEOMETRIC MODEL TO VIEWING ANGLE
Authors: Artyushenko V. V. , Nikulin A. V.
Published: May 2019

In this article we consider a problem of reliable modeling of echo signals and angle noise of distributed objects using twodimensional geometric models with random statistically unrelated signals. The conditions that ensure the invariance of distribution parameters of the angle noise generated by an arbitrary N-point configuration of a two-dimensional geometric model are obtained. In the particular case of a model whose emitters are supplied with signals of equal power, the conditions of invariance are reduced to the location of the model points on the plane in the form of a regular polygon. These results can be used to synthesize mathematical models used for simulating reflections from distributed objects and for developing a hardware-software complex for the simulation of electromagnetic fields reflected from the Earth surface, atmospheric inhomogeneities, the sea surface, etc.

Authors: Alekseytsev S. A. , Gorbachev A. P.
Published: May 2019

In this paper, we present initial design of dual-band dipole antenna which able to perform when shifting high frequency band by inserting of inductive element between high-, and low-frequency dipole arms. Responses of high frequency and bandwidth at –10 dB level on the inductivity are presented in the paper. The maximum value of inductivity to be inserted is about hundreds of nH, hence, it can be implemented by microstrip lines. It is also possible to use lumped elements. Approximations of such responses with polynomials power two and lower are presented in the paper. It is shown, that the bandwidth of the S11 below –10 dB high frequency response has approximately linear behavior, so that can be used when carrying out experimental verifying of the numerical simulations. When simulating radiation characteristics the Russian standard FAF‑4D substrate was used, which can operate at frequencies up to 8–10 GHz.

Authors: Unru N. I. , Ashcherbagin E. I.
Published: May 2019

The notion of a quality criterion for non-tunable band-stop filters is introduced, and on the basis of it a comparison of filters with different designs is performed. The quality criterion takes into account the electrical characteristics of the filter and its dimensions, including the volume, the central frequency of the notch band, the level of total losses in the passbands, the width of the notch band by the level of total losses, the width of the notch band by attenuation level. Thus, it allows you to compare the quality of design and manufacture of passive notch filters of various types. The necessary analytical expression is presented, and for a number of variants of filter execution, the corresponding calculation results are given. The stated materials allow us to estimate and optimize the system of interrelated parameters of filters of an arbitrary physical structure.

Authors: Unru N. I. , Ashcherbagin E. I. , Arashtaev A. V.
Published: May 2019

The paper considers the implementation of tunable band-stop resonators and filters manufactured on a microstrip with a defective base. The restructuring of the band-stop resonators and filters is proposed to be carried out using varactors and trimmers. Experimental and calculated data on the electrical characteristics of the band-stop resonators and filters in the tuning range are given. According to the comparison of the experimental and calculated tuning characteristics of the amplitude-frequency characteristics of the band-stop resonators and filters, it is noted that the notch band for two-and three-cavity filters based on a microstrip with a defective base varies quite strongly in the tuning range. The presented materials allow to carry out a preliminary assessment of the tuning properties of a relatively new class of inexpensive frequency filters and resonators.

Authors: Mitkov A. S. , Stolyarenko A. A. , Rubanovich M. G.
Published: May 2019

The article presents the results of a study of the frequency properties of a multi-stage high-power attenuator with attenuation of 10 dB in the frequency range 0–3 GHz, obtained on a dielectric substrate made of beryllium ceramics. For its construction, microstrip filters with quarter-wave couplings and dissipative losses are used, as well as additional film resistors made in the form of trapezoidal plumes. These loops have a minimum size in the area of a short circuit. The design features of wide-band microwave attenuators of high power are determined, including the conditions for ensuring uniform distribution of the dissipated microwave power and distribution of the resonant frequencies of low-Q resonators. Equivalent circuits were compiled, which allow to determine the initial structure of the attenuator and optimize its frequency characteristics for any power level.
MODELING OF FIBER-OPTIC COMMUNICATION CHANNEL FOR QUANTUM CRYPTOGRAPHIC SYSTEMS
Authors: Minaev V. A. , Korolev I. D. , Kulish O. A. , Mazin A. V.
Published: May 2019

The existing methods of information delivery to the strategic and tactical management of many government agencies are expensive, not always reliable and efficient. Therefore, quantum cryptographic systems (QCS) have been actively developed in recent years. However, there are problems with the use of the QCS associated with the reliability of information transfer. First, the existing fiber-optic communication channels (FOCC) are not designed to transmit single-photon signals, which leads to the complexity of their cryptographic protection. The second is insufficiently methodically developed calculation of energy losses and errors in the evaluation of the characteristics of information transfer in FOCC QCS. In article the analysis of the energy loss factors in the classical fiber-optic channel is carried out and the additive loss formula is discussed in detail. Then we consider the fiber-optic channel of quantum information transmission with the use of integrated optical devices. The additive formula of optical losses in such a channel is discussed. The features of losses in integrated optical devices are shown. The features of quantum cryptographic system of information transmission are considered. As a result, the model of FOCC QCS taking into account energy losses is presented, which allows competently in theoretical terms and visualize the passage of information through modern quantum cryptographically secure telecommunications while providing control in government structures.

Authors: Coswig Victor , Sant' Ana Jader , Coelho Maicon Nascimento , Pereira Moro Antonio Renato , Diefenthaeler Fernando
Published: May 2019

BACKGROUND

TReaction is a mobile app developed to determine strike response time at low cost and with easy application in combat sports. However, the validity and accuracy of the response time obtained by the TReaction app has not yet been evaluated.

OBJECTIVE

This study aimed to test the validity and reliability of the TReaction app in measuring motor response time in combat sports.

METHODS

A total of two athletes performed 59 strikes to assess the response time upon visual stimulus using the TReaction app simultaneously with a high-speed camera. Accuracy of the measure was verified using a computer simulator programmed to discharge visual stimuli and obtain the response time. Pearson correlation, Student t test for dependent samples, and the Bland-Altman analysis were performed. Accuracy was verified using the intraclass correlation coefficient. Effect size (g) and the typical error of measurement (TEM) were calculated. The significance level was set at P<.05.

RESULTS

No significant difference (P=.56) was found between both systems. The methods presented a very strong correlation (r=0.993). The magnitude of differences was trivial (g<0.25), and TEM was 1.4%. These findings indicate a high accuracy between the computer screen and the mobile app measures to determine the beginning of the task and the response time.

CONCLUSIONS

Our findings suggest that the TReaction app is a valid tool to evaluate the response time in combat sports athletes.

BACKGROUND

Around the world there is a growing expansion in m-health due to the ease of access to mobile phones and broadband internet. The field of nursing care of the patient with stroke has proven to be receptive to this technological evolution, both for the identification of risk factors in the population, as well as in the training and certification of professionals in the nursing care of stroke patients. In this way, nurses participate not only as developers of technologies for care, but also with scientific validation, with results of support to health services and training.

OBJECTIVE

To evaluate the efficacy of a mobile application as a learning aid for nurses and nursing students to identify and care for stroke patients in a region of southern Brazil.

METHODS

A study on the development and technological evaluation of the instructional design stages of an application was conducted for the period from July to November 2017 in a region of southern Brazil. This involved two clinical cases according to Problem Based Learning and Persuasive Technology. The quality evaluation was based on the Learning Object Review Instrument (LORI®). The resulting data were processed and analyzed using the R® programming language version 3.4.3. We used descriptive statistics (mean, median, minimum value, maximum value, and standard deviation) to compare both groups and a non-parametric test with a 5% significance level.

RESULTS

The mean of the variables was high (described as "very good"). The variables including content quality, learning goal alignment, motivation, feedback, and adaptation were notable with averages ranging from 4.91 (± 0.28) to 4.97 (± 0.16). Statistical analyses demonstrated that there was agreement between the nurse and student groups for the variables motivation (0.012), presentation design (0.019), re-usability (0.18) and standards compliance (0.45).

CONCLUSIONS

It was determined that the mSmartAVC application satisfies international quality certification criteria and improves the decision-making and clinical evaluation of nurses and students.

Inter-annual variability of oceanographic conditions and phytoplankton in Valparaíso Bay (~33°S), central Chile
Authors: Aparicio-Rizzo Pilar , Masotti Italo
Published: May 2019

The inter-annual variability of oceanographic conditions and phytoplankton abundance and biomass was studied using 10 years (1986-1996) of in situ observations at a fixed station in Valparaíso Bay (~33ºS). The time series analysis revealed that strong S-SW winds drive a quasi-permanent upwelling activity that maintain the nutrients availability in the water column to fuel the phytoplankton in the bay. The most important changes in bio-oceanographic conditions were observed during 1987 El Niño event, which was characterized by higher temperatures but lower values for salinity, nitrate, and phosphate concentrations, together with a decrease of phytoplankton biomass compared to 1988 La Niña event when colder, saltier, and nutrient-rich upwelled water were observed. High Aconcagua River discharges were observed during the El Niño conditions (1987-1988 and 1993), which led to a decrease in surface salinity and a high abundance of dinoflagellates. Two periods with differences in bio-oceanographic conditions were observed; 1988-1992 showed lower temperatures but higher nutrients (nitrate), phytoplankton biomass and abundance of diatoms than 1993-1996 period. Throughout the study period, positive trends in upwelling activity was registered accompanied by a fall in phytoplankton biomass and dinoflagellate abundance. This paper provides new evidences concerning the influence of El Niño Southern Oscillation (ENSO) in phytoplankton and oceanographic conditions in the coastal upwelling off central Chile.

Published: May 2019

Background and Objectives: In Ethiopia, family medicine began in 2013. The objective of this study was to compare family medicine residents’ attitudes about training in Ethiopia with those at a program in the United States.
Methods: Family medicine residents at Addis Ababa University in Addis Ababa, Ethiopia and the University of Maryland in Baltimore, Maryland completed a 43-item Likert scale survey in 2017. The survey assessed residents’ attitudes about residency education, patient care, independence as family physicians, finances, impact of residency on personal life, and women’s issues. We calculated descriptive statistics on the demographics data and analyzed survey responses using a two-sample t-test.
Results: A total of 18 (75%) Ethiopian residents and 18 (60%) US residents completed the survey (n=36). The Ethiopian residents had a wider age distribution (25-50 years) than the US residents (25-34 years). More US residents were female (72%) compared to the Ethiopian cohort (50%), while more Ethiopian residents were married (72%) compared to the US cohort (47%). There were statistically significant differences in attitudes toward patient care (P=0.005) and finances (P<0.001), differences approaching significance in attitudes toward residency education, and no significant differences in independence as family physicians, the impact of residency on personal life, and women’s issues in family medicine.
Conclusions: Across two very different cultures, resident attitudes about independence as family physicians, the impact of residency on personal life and women’s issues, were largely similar, while cross-national differences in attitudes were found relative to residency education, patient care, and finances.

Published: May 2019

Background and Objectives: There is a paucity of longitudinal data documenting the temporal development of distress and burnout during medical school. The aim of this study was to examine trends and identify stressors associated with medical student distress over 4 years of medical education.
Methods: Medical students from the class of 2016 at a Liaison Committee on Medical Education-accredited medical school completed surveys nine times from orientation through after the residency match. Surveys included demographic variables and measured distress domains using the Medical Student Well-Being Index. The authors used Microsoft Excel to calculate the proportion of students screening positive for individual distress domains at each of the nine acquisition periods for descriptive analysis.
Results: Students completed 886 total surveys for an 85% response rate, which was relatively consistent across collection periods. Medical student distress and burnout increased from two (2%) to 12 (12%) respondents and from 19 (17%) to 37 (38%) respondents, respectively, from matriculation through after the residency match (P<0.01). Depersonalization increased from 15 (13%) to 34 (35%) respondents and emotional exhaustion increased from six (5%) to 22 (22%) respondents across 4 years of medical education (P<0.01). Emotional exhaustion peaked after medical school year 1, at 37 (45%), and year 3, at 45 (44%) respondents, with improvement after summer break and residency match.
Conclusions: The results supported the literature demonstrating the development of burnout during medical school. Depersonalization increased early in the education process with minimal regression after development. Emotional exhaustion demonstrated a surprising increase after exposure to clinical clerkships. Further studies could support or refute the universality of these trends and evaluate prevention and intervention efforts targeting these key inflection points.

Background and Objectives: As part of a national pilot, the Lehigh Valley Family Medicine Residency Program implemented curricular changes to emphasize family medicine identity. These changes included limiting first-year inpatient experiences, adding “interval” outpatient weeks, and increasing family physician mentorship. This study explores how postgraduate learners describe their professional identities within the context of their chosen specialty, as defined by Family Medicine for America’s Health (FMAHealth).
Methods: This qualitative study approached family medicine identity formation from a social constructionist framework using evolved grounded theory. We performed a thematic analysis of focus groups conducted over 12 years with first-year residents (n=73). Then, utilizing a matrix analysis, articulations about professional identity were compared with structural components of the FMAHealth definition of the specialty. Three cohort groups (Preimplementation, Implementation, and Postimplementation) were defined to conduct a longitudinal comparison.
Results: Six unique biosketches synthesizing the analyses emerged. Expansion in ability to articulate professional identity was evident not only across, but also within cohort groups. The Preimplementation cohort entered and left their first year identifying as relationship-centered generalists desiring guidance from role models. The Implementation learners used more FMAHealth language to describe their practice, later recognizing the potential it held for patient care. Similarly, the Postimplementation cohort entered with a broader view of family medicine and exited wondering how to help advance its reach.
Conclusions: Curricular changes placing interns within specialty-relevant learning settings coincide with thematic differences in articulations in professional identity. These findings suggest that experiential learning and role modeling contribute to professional identity formation among graduate medical learners.

Cálculo da complexidade organizacional em dois arranjos produtivos da indústria calçadista
Authors: Sellitto Miguel Afonso , Guimarães Marcelo Giovani
Published: May 2019

Este artigo apresenta uma metodologia quantitativa para cálculo e eventual controle da complexidade em arranjos interorganizacionais. A pesquisa propôs e testou uma metodologia para calcular a complexidade relativa de um arranjo pela quantidade de informação que as partes do arranjo devem trocar para fins de gestão. O teste foi realizado em dois arranjos presentes na indústria calçadista: uma cadeia de suprimentos e uma rede de ateliers de costura. Entende-se que estes tipos de arranjos organizacionais apresentam características que podem ser descritas segundo a teoria da complexidade e que seja desejável conhecer e controlar sua complexidade por meio do índice calculado. A complexidade calculada da cadeia foi de 12,67% e a da rede foi de 22,67%.
Gestão da inovação: análise e síntese dos conceitos
Authors: Stefanovitz Juliano Pavanelli , Nagano Marcelo Seido
Published: May 2019

Este artigo apresenta um panorama teórico do atual estágio da literatura científica voltada para a gestão da inovação, tendo como objetivo organizar os conceitos apresentados e propor um modelo integrado para ela. Apesar da importância da inovação ser amplamente reconhecida, há consenso de que as práticas de gestão que a potencializam permanecem ainda não totalmente desvendadas. Sabe-se que o processo inovador é complexo. Vários autores já verificaram esta complexidade ao mostrar que ele envolve uma intrincada composição de risco e incerteza, e a necessidade de intensa orquestração multifuncional na busca permanente de sintonia entre criação e disciplina e a capacidade de adequar com rapidez a configuração e o contexto organizacional. Reconhece-se também que a literatura ainda carece de pesquisas que agreguem contribuições de diversas áreas do conhecimento em modelos integrados para gestão da inovação. O presente artigo apresenta uma reflexão para futuras pesquisas ligadas ao tema.

O seguinte artigo aborda a aplicação dos conceitos de estratégia de produção em uma organização, bem como sua interface com a gestão de processos. Estratégia de Produção é uma forma de definir diretrizes de acordo com os objetivos de desempenho. E a Gestão de Processos mostra-se como uma ferramenta para mapear e facilitar a visualização de aspectos ligados a critérios competitivos empresariais. Este artigo objetiva mostrar de que forma a matriz importância-desempenho direciona a estratégia de produção de uma organização. A empresa em estudo possui problemas relacionados à atividade ambulante e à entrega de sorvetes em seus pontos de venda; e, com base nessas duas carências, foi desenvolvido um estudo de caso e análises qualitativas, a partir de visitas à empresa, pesquisas bibliográficas e tratamentos estatísticos - este último foi pautado na análise de importância e desempenho dos critérios competitivos organizacionais selecionados a partir de um planejamento estratégico. Dessa forma, obteve-se uma estratégia de produção voltada para os aspectos críticos relacionados aos problemas da empresa, permitindo à mesma, o aumento das vendas ambulantes e a diferenciação dos nichos de mercado do setor de sorvetes. Assim, a estratégia elaborada aumentou a adaptabilidade da organização frente ao mercado, orientando-a a seus clientes.
Administração de estoques: diferentes formas de medição da acuracidade
Authors: Favaretto Fabio
Published: May 2019

Este artigo trata de falta de padronização da informação da acuracidade de um estoque. O objetivo é apresentar diferentes formas de medição da acuracidade de estoques e fazer considerações a respeito destas medidas. Falhas na contagem e no registro das movimentações do produto incidem no sistema de controle deste estoque. Foram analisadas a diferença média dos saldos dos produtos em quantidade e em proporção e o número de produtos com diferença entre os saldos. Foram criados cenários com diferentes probabilidades de ocorrência de erro em cada movimentação do estoque. Para cada cenário foram consideradas situações distintas em relação à tolerância ao erro: sem tolerância e com tolerâncias de 1 e 5%. Para que o decisor envolvido na gestão de um processo de controle de estoque tenha uma boa visão da acuracidade do mesmo, sugere-se a utilização conjunta das informações das medidas da diferença proporciona e a medida do número de produtos que apresentam diferença entre os saldos.
O papel da orientação empreendedora e da informação de mercado na geração de inovação radical

Published: May 2019

Apesar do grande interesse e da relativa consolidação teórica a respeito do tema de antecedentes da inovação radical, uma série de estudos vem demonstrando que ainda há uma série de recursos organizacionais que podem representar participação importante neste fenômeno organizacional. Visando um aprofundamento deste tema, este trabalho aborda o papel do capital social externo como elemento moderador no impacto de dois antecedentes na criação de inovação radical, especificamente a orientação ao empreendedorismo e a geração de informação. O estudo envolveu empresas brasileiras de diversos setores. Um modelo teórico foi desenvolvido e testado pela aplicação da técnica de modelagem de equações estruturais e análise multi-grupo. Os resultados encontrados apontam para uma situação em que a intensificação do capital social externo não registra impacto significativo no caráter empreendedor das empresas quando do desenvolvimento de inovação radical e, surpreendentemente, diminuiu significativamente a participação das informações advindas do mercado neste processo de desenvolvimento.

Published: May 2019

A cadeia produtiva de frango de corte é pressionada pelos desafios do atual cenário mundial de intensa competitividade e leis de proteção ambiental a buscar fontes alternativas no aproveitamento dos resíduos gerados como os pés de frango visando vantagem competitiva e uma atividade de maior sustentabilidade. O presente estudo propõe a produção de gelatina como uma nova perspectiva para a cadeia produtiva de frango discutindo os principais elos envolvidos, contribuindo dessa forma com a comunidade acadêmica e científica com informações sobre aproveitamento de subprodutos na busca pela sustentabilidade e competitividade. Nesse sentido, apresenta-se um processo experimental de elaboração de gelatina a partir de tarsos de frango. A análise de aceitabilidade foi realizada por meio de análise sensorial. A proposta de novo destino aos pés de frango, considerados resíduos nos frigoríficos, foi possível, obtendo-se, portanto, vantagem competitiva tanto para o frigorífico, propiciando fonte alternativa de lucro, como para a indústria de gelatina onde a inovação em tipo de matéria-prima e novos processos industriais determinam adaptabilidade, flexibilidade no processamento e competitividade no mercado.
