Analysis of close approach and collision probability between operational satellites and/ or space debris
Authors: HALAWA M. G. , ABDEL-AZIZ Yehia , YOUSSEF M.
Published: September 2020

In recent years, the number of space debris has increased significantly, which can threaten the safety of operational satellites. In this paper we developed an accurate model for active satellite protection from collision in order to determine close approaches between two objects (satellites and /or debris) using the Hoot's method and the time of close approach. We calculate the minimum relative distance considering J2 and atmospheric drag perturbations, and compared it to the close approach distance. The Collision probability between two closed objects is calculated using Chan model and analyzed in a given time-scale to avoid any dangerous collision. We applied our models on the cataloged debris (more than 1000) resulted from the crash between Iridium 33 and Cosmos 2251; in addition, ten satellites from the Iridium satellites list at the same altitudes of the debris crowdie region are considered. The numerical results have shown one real case of close approach with high probability of collision that may threaten one of those active satellites.
Who are behavioural public policy experts and how are they organised globally?
Authors: Straßheim Holger
Published: September 2020

Behavioural public policy has spread internationally over recent years. Worldwide, expert units are translating insights from behavioural sciences into policy interventions. Yet, behavioural expert networks are a puzzling case. They seem to oscillate between two modes of collective action: as an epistemic community, they are based on the consensual belief that biases in behaviour pose a problem for policymaking. As an instrument constituency, they bring together a diversity of actors, unified not by consensual beliefs about problems but by practices of promoting behavioural instruments as solutions. Drawing on a review of literature, this article provides a systematic analysis of the relation between epistemic communities and instrument constituencies. It argues that there has been an ‘agency shift’ from one mode to the other. The implications are that experts should be aware of the fact that the instruments they are proposing might develop a political life of their own.
‘Personalised risk’ in paid care work and the impacts of ‘gig economy’ care platforms and other market-based organisations
Authors: Macdonald Fiona
Published: September 2020

Research has identified ‘personalised risks’ for workers due to changes in the public/private dimensions of care where workers are directly employed or engaged by care users in individualised care systems. Drawing on interviews with workers in Australia’s new individualised disability services market, the research explores personalised risk and the effects of involvement in personalised care relationships of market-based organisations, including online digital care platforms. It finds that rather than having a protective role, both digital platforms and employing organisations can increase risks for workers in individualised care relationships.
Dynamic oscillatory powers, cross sections, and energy efficiencies in coherent optical heterodyning
Authors: Mitri F. G.
Published: September 2020

In a recent analysis [J. Quant. Spectrosc. Radiat. Transfer 250, 106994 (2020)JQSRAE0022-407310.1016/j.jqsrt.2020.106994], the emergence of a dynamic oscillatory radiation force in coherent optical/electromagnetic (EM) heterodyning has been demonstrated for TM- and TE-polarized amplitude-modulated (AM) plane waves interacting with a lossless dielectric circular cylinder. A dynamic oscillatory component of the EM radiation force emerged at the beat frequency of two interfering fully correlated wave fields driven at slightly different frequencies. This work extends the scope of that analysis to examine the oscillatory behavior of energy-related physical observables from the standpoint of energy conservation applied to scattering. Partial-wave series for the oscillatory scattering, extinction and absorption powers, cross sections, and energy efficiencies are derived in cylindrical coordinates for a circular homogeneous cylinder material using the short-term time averaging (STTA) procedure and Poynting’s theorem. AM plane progressive waves incident upon a lossless dielectric cylinder with arbitrary radius are considered. Numerical computations of the oscillatory scattering and extinction energy efficiencies illustrate the theory. A criterion based on computing and quantifying accurately the percentage (or relative) error between the dynamic (oscillatory) extinction and scattering efficiencies is developed and numerically evaluated. This benchmark tool provides physical validation and verification of the results from the standpoint of energy conservation. The results show that the percent (relative) error increases at the resonances of the dielectric cylinder as its refractive index increases. Far from the resonances, the oscillatory component of the STTA remains appropriate because the percent (relative) error does not exceed 0.05%, provided the beating difference frequency is much smaller than that of the primary waves. The case of an absorptive dielectric cylinder is also illustrated and discussed. The present analysis is of fundamental importance in order to validate dynamic radiation force computational results from the standpoint of energy conservation in the development, design, and optimization of oscillatory optical heterodyne tweezers and tractor beams in related applications in particle manipulation.
Efficient generation of heralded narrowband color-entangled states
Authors: Zhang Xiao-Jun , Wu Jin-Hui , La Rocca G. C. , Artoni M.
Published: September 2020

We show that narrowband two-color entangled single Stokes photons can be generated in a ultra-cold atoms sample via selective excitation of two spontaneous four-wave mixing (SFWM) processes. Under certain circumstances, the generation, heralded by the respective common anti-Stokes photon, is robust against losses and phase-mismatching and is remarkably efficient owing to balanced resonant enhancement of the two four-wave mixing processes in a regime of combined induced transparency. Maximally color-entangled states can be easily attained by adjusting the detunings of the external couplings and driving fields, even when these are quite weak.
Onboard absolute radiometric calibration and validation of the satellite calibration spectrometer on HY-1C

Published: September 2020

As the reference radiometric calibration standard of sensors on the Haiyang-1C (HY-1C) satellite platform, the satellite calibration spectrometer (SCS) is equipped with an onboard calibration system composed of double solar diffusers and an erbium-doped diffuser to monitor the postlaunch radiometric response change. Herein, through onboard calibration data analysis, the calibration diffuser performance remains stable without degradation, and the Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra is adopted as a reference to repeatedly verify onboard radiometric calibration results by selecting different dates and reflectance scenes. The SCS equivalent reflectance is obtained by combining the mean digital number (DN) of the SCS crossing area image with the radiometric calibration coefficient. The spectral reflectance is obtained via interpolation and iteration, which is adopted as the actual MODIS incident pupil spectral reflectance because the small imaging time interval can be ignored and almost vertically observed, and it is convoluted with the MODIS spectral response function to obtain the predicted equivalent reflectance. Validation is completed by comparing the predicted MODIS equivalent reflectance to the measured value based on the onboard calibration coefficient. The results show that (1) the difference between the measured and predicted MODIS band equivalent reflectance is between -0.00466 and 0.0039, and (2) the percentage difference between the measured and predicted MODIS band equivalent reflectance ranges from 4.17% and 1.24%, indicating that the calibration system carried on HY-1C can perform high-precision SCS radiometric calibration, meeting the cross-calibration accuracy requirements of other loads on the same platform.
Multi-wavelength random fiber laser with switchable wavelength interval
Authors: Huang Ping , Shu Xuewen , Zhang Zuxing
Published: September 2020

A random fiber laser with flexible wavelength interval switching is proposed and demonstrated through two switching methods. One is to change the effective structure of the laser cavity by controlling the switches of 980 nm pump laser diodes (LDs) for erbium-doped fibers (EDFs), which can achieve the switching of the wavelength interval from a single Brillouin frequency shift (BFS) of 0.088 nm to a double BFS of 0.176 nm. Another method is to manipulate the gain provided by the two EDF amplifiers by controlling the power of the three 980 nm LDs, thereby realizing the optical switching of the wavelength interval. This kind of wavelength interval switchable random fiber laser increases the flexibility and functionality of multi-wavelength light sources, and further expands the application range of the random fiber lasers. Furthermore, the alternative wavelength interval switching mechanisms with simple structure enable it to meet the application requirements of various occasions.

Published: September 2020

In this paper we investigate the chromatic dispersion impact on the quantum key distribution system based on multi-mode weak coherent phase-coded states. We provide an asymptotic secure key rate estimation, taking into account error detection probability due to chromatic dispersion. We demonstrate numerically and experimentally that the effect of chromatic dispersion in an optical fiber without any compensation hinders the secret key distribution at a distance more than 53 km. Finally, we propose a modification to the considered quantum communication system in order to mitigate the influence of chromatic dispersion on its performance.
Paraxial and tightly focused behaviour of the double ring perfect optical vortex
Authors: Rickenstorff Carolina , Gómez-Pavón Luz del Carmen , Sosa-Sánchez Citlalli Teresa , Silva-Ortigoza Gilberto
Published: September 2020

In this paper we compare the intensity distributions in the paraxial and tightly focused regimes corresponding to a double ring perfect optical vortex (DR-POV). Using the scalar diffraction theory and the Richards-Wolf formalism, the fields in the back focal plane of a low and high (tight focusing) NA lens are calculated. In the paraxial case we experimentally observed a DR-POV whose rings enclose a dark zone thanks to the destructive interference introduced by a π phase shift. In the tightly focused regime, however, the numerical simulations showed that the intensity near the focus is influenced by the input field polarization and it is not intuitive. In both cases we found that the dark region subtended between the rings has a minimal width that is inversely proportional to the pupil radius of the system, reaching 0.42λ for the radially polarized DR-POV. For the tightly focused case, we calculated the optical forces in the transversal and longitudinal coordinates exerted on a metallic particle. As a result, it is theoretically demonstrated that the circularly polarized DR-POV can trap Au metallic particles in 3D using a light wavelength close to its resonance.
Transformation of a Hermite-Gaussian beam by an Airy transform optical system
Authors: Zhou Guoquan , Wang Fei , Chen Ruipin , Li Xia
Published: September 2020

Analytical expression of the Airy transform of an arbitrary Hermite-Gaussian beam is derived. The optical field in the x-direction of the Airy transform of Hermite-Gaussian beams with transverse mode number m is the sum of the zero-order derivative to mth-order derivative of the Airy function with different weight coefficients. The analytical expressions of the centre of gravity and the beam spot size of an arbitrary Hermite-Gaussian beam passing through an Airy transform optical system are also presented, which are very concise. Because the Airy transform of a Hermite-Gaussian beam has the same evolution law in the two transverse directions, only the effects of the control parameter α and the transverse mode number m on the normalized intensity distribution, the centre of gravity, and the beam spot size in the x-direction are theoretically investigated, respectively. The Airy transform of Hermite-Gaussian beams is also realized in the experiment. The influence of the control parameters on the normalized intensity distribution, the centre of gravity, and the beam spot size is experimentally investigated, respectively. The experimental results are consistent with the theoretical simulation results. When Hermite-Gaussian beams pass through an Airy transform optical system, the number of lobes may change, and the importance of lobes with the same status in the input plane may become different. By using the Airy transform of Hermite-Gaussian beams, the practical applications of Hermite-Gaussian beams can be extended.
Polarization-multiplexed Huygens metasurface holography
Authors: Wang Zhuochao , Ding Xumin , Liu Shengying , Zhang Kuang , Wu Qun
Published: September 2020

Huygens metasurface, as a subcategory of metamaterials, shows great potential in the capacity and efficiency of electromagnetic wave manipulation within a subwavelength scale. Here, the transmission-type Huygens metasurface is demonstrated for complete and independent control of orthogonally polarized transmitted waves by constructing pairs of crossed electric and magnetic resonances in three-sheet meta-atoms as the building blocks for holographic imaging. Under incoherent horizontally and vertically polarized illuminations, two designated holographic images with negligible mutual interferences are accomplished with at least 62.95% measured imaging efficiency and 63.53 signal-to-noise ratio, respectively. This work addresses several major issues in traditional polarization-multiplexed holography with regard to transmission-coefficient manipulation capacity, image fidelity, and simple fabrication technique, empowering advanced research and applications in polarization-selective microwave devices and information processing.
4-HNE Immunohistochemistry and Image Analysis for Detection of Lipid Peroxidation in Human Liver Samples Using Vitamin E Treatment in NAFLD as a Proof of Concept
Authors: Podszun Maren C. , Chung Joon-Yong , Ylaya Kris , Kleiner David E. , Hewitt Stephen M. , Rotman Yaron
Published: September 2020

Lipid peroxidation is a common feature of liver diseases, especially non-alcoholic fatty liver disease (NAFLD). There are limited validated tools to study intra-hepatic lipid peroxidation, especially for small specimen. We developed a semi-quantitative, fully automated immunohistochemistry assay for the detection of 4-hydroxynoneal (4-HNE) protein adducts, a marker of lipid peroxidation, for adaptation to clinical diagnostics and research. We used Hep G2 cells treated with 4-HNE to validate specificity, sensitivity, and dynamic range of the antibody. Staining and semi-quantitative automated readout were confirmed in human needle-biopsy liver samples from subjects with NAFLD and normal liver histology. The ability to detect changes in lipid peroxidation was tested in paired liver biopsies from NAFLD subjects, obtained before and after 4 weeks of treatment with the antioxidant vitamin E (ClinicalTrials.gov NCT01792115, n=21). The cellular calibrator was linear and NAFLD patients had significantly higher levels of 4-HNE adducts compared to controls ( p=0.02). Vitamin E treatment significantly decreased 4-HNE ( p=0.0002). Our findings demonstrate that 4-HNE quantification by immunohistochemistry and automated image analysis is feasible and able to detect changes in hepatic lipid peroxidation in clinical trials. This method can be applied to archival and fresh samples and should be considered for use in assessing NAFLD histology.

Deaf Academic Leader's Perspective: A Proposed Framework for Decision-Making Process in Higher Education for Deaf Students
Authors: Laury Dean J
Published: September 2020

This article examines the question, “How do the intersectional relationships between the dual process, heuristic/bias, and decision-making models manifest in an educational leader’s decision-making framework when the leader possesses a deaf lens?” Perceptions that could have an emotional impact on the decision-making process are shared. Research in the field is discussed and supplemented by the author’s perspectives, experiences, and document analysis to articulate a proposed framework. The goal of implementing the proposed framework is to increase the probability of obtaining better decisions, given that educational leaders with deaf lenses tend to be visually receptive learners who depend on personal and professional philosophy and experience. The selected perceptions and phrases from the intersectional relationship categories forming the proposed framework were based on: A) information (sought and processing), B) time (as phase), and C) emotional responses. In this article, explored is the perspective of an educational leader with a deaf lens that led to potential influences upon the decision-making processes and validation of a new framework. However, the implication of this was that no single decision model is necessary the correct model or is responsible for any outcome. More significantly, the work demonstrated the proposed framework is to help other educational leaders with a deaf lens improve their knowledge, understanding, and perspective of their decisions since those decisions impact stakeholders. This framework and expertise can be beneficial to prospective educational leaders.
Transition to Postgraduate Study at Master’s Level Lessons Learned: Lessons Learned from Students’ Evaluations of an Online Induction Resource
Authors: Robb Lindsey , Moffat Sheena
Published: September 2020

Evidence from UK universities’ Postgraduate Taught Experience Survey (PTES) concluded that whilst confident and experienced in their area of practice, some find the prospect of returning to study in an on-line environment and making the transition to Master’s Level daunting. In recognition of this, a small group created an online resource ‘Preparation for study at Master’s Level’ which students have access to as part of the induction process for the taught postgraduate programme, MSc in Advanced Practice in the School of Health and Social Care at Edinburgh Napier University. 

This paper reports on findings of an evaluation of the on-line induction resource using NOVI survey to explore student’s views.  73% of respondents (n=25) felt that the online resource was helpful in increasing confidence about online learning and studying at Master’s level. Qualitative comments reflect other research signifying the importance of social interaction and ongoing support to co-create understanding and development of skills.  The lessons learned from students’ lived experience informed amendments to programme online and face to face content and had an impact on the programme team by rekindling a programme focus.

Though particular to one programme within one university, the findings mirror themes highlighted elsewhere; that transition to Master’s level is complex, involving change and exploration of identity, anxiety about what Master’s level entails, all of which make for an emotionally challenging experience. Others who support postgraduate students studying at Master’s level, can learn from this experience.
Harnessing the Use of OERS in Teacher Education
Authors: Carlson Catie E. , Meadows Michelle L.
Published: September 2020

Open educational resources (OERs) are used by teachers to help find resources to integrate into their classroom and find resources for teaching and learning (UNESCO, 2019). The purpose of this study was to investigate the OERs that pre-service teachers (PSTs) used within their field experiences during one semester in a clinical course. To address the purpose of this study, the researchers collected survey data and lesson plans before and after conducting two OER lesson plan trainings. Findings suggest PSTs may benefit from learning about OER resources, how to use them when planning lessons, and how to cite them properly in lessons within all subject areas.

Published: September 2020

INTRODUCTION:

Defecation desire (DD) is an important physiological component of normal defecation. However, knowledge of DD in the general population and in individuals with chronic constipation (CC) is lacking. We aimed to assess the prevalence of DD in the general population and individuals with CC and to understand the impact of treatment on DD among individuals with CC.

METHODS:

We conducted an online questionnaire survey targeting the Japanese general population in 2019. DD was reported as never, rarely, usually, or always. Individuals who self-reported constipation and met the Rome IV criteria for functional constipation but did not for irritable bowel syndrome were included in the CC group, while the same number of age-/sex-matched controls who met neither functional constipation nor irritable bowel syndrome criteria was included in the non-CC group. Individuals who reported DD as rarely or never were defined as having loss of DD (LODD).

RESULTS:

Of the 20,986 participants, 2,587 were included in the CC group (12.3%). LODD was significantly higher in the CC individuals than in the non-CC controls (57.4% vs 8.3%, respectively,P< 0.001, odds ratio 14.84 [95% confidence interval 12.65–17.42]). Satisfaction with treatment for constipation was lower in individuals with persistent LODD (25.9%) compared with those with improved LODD (56.5%) on treatment (P< 0.001, odds ratio 2.48 [1.39–4.43]).

DISCUSSION:

LODD is common in CC and is associated with decreased satisfaction to treatment. Greater attention should be paid to DD when treating patients with CC.

Design Pedagogy: The New Architectural Studio and Its Consequences
Authors: Deamer Peggy , Deeg Lohren , Metz Taylor , Tursky Richard
Published: September 2020

This article argues that the typical architectural studio is both outmoded and irresponsible. It is outmoded because it typically is organized around a nineteenth-century model of design virtuosity, and it is irresponsible because it ignores pressing and current spatial justice problems. It also takes to task the aura of the academic setting in which the formally motivated studio reigns supreme. In lieu of this model of architectural education, the article argues for an education that empowers graduates to tackle the major problems that society currently faces: housing, climate, income inequality/unemployment and health. To do this, it acknowledges but suggests overthrowing the many institutional hurdles keeping architectural education attached to the status quo.
ASSIMETRIA DE CUSTOS NO GERENCIAMENTO DE RESULTADOS
Authors: Pereira Nevison Amorim , Tavares Marcelo
Published: September 2020

O objetivo dessa pesquisa foi verificar a relação entre os níveis de assimetria de custos e o gerenciamento de resultados. A amostra é composta por 157 empresas brasileiras de capital aberto no período de 2008 a 2017, somando 1570 observações. Para a análise dos dados, utilizou-se os modelos de regressão múltipla (linear) e o modelo logit (não linear). Quanto aos resultados, inicialmente evidenciou-se que parte das empresas apresentou assimetria nos custos e que o gerenciamento de resultados foi confirmado nas empresas que relatam lucros positivos que estão próximos de zero, isto é, evitam divulgar perdas incorridas no período. Posteriormente, demonstrou-se que o gerenciamento de resultados e a assimetria de custos estão associados negativamente. Porém, esse resultado se mostrou significativo apenas para o gerenciamento de atividades reais. Conclui-se que as empresas que apresentam assimetria de custos têm menor gerenciamento de resultados por atividades reais apenas no setor industrial. As explicações para esse resultado são a elevada estrutura de custos fixos desse setor e os incentivos pessoais dos gestores, conforme a Teoria da Agência, que implicam em maior assimetria de custos. Uma das contribuições da pesquisa é apontar aos usuários da informação contábil que a análise do comportamento dos custos das empresas pode indicar se os gestores estão se utilizando do gerenciamento de resultados para ajustar o lucro.
POLÍTICA DE DESONERAÇÃO DO IPI E SUA IMPLICAÇÃO NA ARRECADAÇÃO PRÓPRIA DOS MUNICÍPIOS BRASILEIROS
Authors: Barbosa Lucas Tristão , Abrantes Luiz Antônio , Brunozi Júnior Antônio Carlos , Almeida Fernanda Maria de
Published: September 2020

A política de desoneração do IPI foi implementada a partir de dezembro de 2008, como resposta à crise mundial do mesmo ano que afetou o Brasil. Nesse sentido, o governo federal definiu a redução dos percentuais das alíquotas de diferentes produtos em diversos setores. Considerando esse cenário, o objetivo geral deste artigo consistiu em avaliar a relação das políticas de desonerações do IPI, a partir de 2009 até 2013, último ano da política, na arrecadação própria dos municípios brasileiros. Especificamente, pretendeu-se verificar a existência de variabilidade dessa arrecadação em função da heterogeneidade dos municípios, típica de uma país de dimensões continentais e disparidades socioeconômicas como o Brasil. Este estudo se justifica tendo em vista que parte da arrecadação do IPI compõe a receita dos municípios, os quais em sua maioria apresentam grande dependência das transferências intergovernamentais. Os subsídios foram obtidos na base de dados do FINBRA e IBGE, compreendendo os períodos pautados do início de 2004 ao final de 2015. Para a operacionalização dos dados, foi utilizado o modelo econométrico de dados em painel multinível. Os resultados demonstraram que a arrecadação própria dos municípios brasileiros, considerando toda a amostra, foi afetada de forma positiva a partir da política de desoneração do IPI. É possível concluir que a arrecadação própria dos municípios brasileiros analisados, de modo geral, foi afetada pela política fiscal do IPI, atendendo à expectativa inicial. A conclusão é justificada por dois apontamentos não excludentes: efeito estabilizador da política do IPI e esforço de arrecadação própria dos municípios.
IMPACTOS DA LEI 11.312/06 SOBRE A PARTICIPAÇÃO DE INVESTIDORES ESTRANGEIROS NO VOLUME DE TÍTULOS PÚBLICOS BRASILEIROS
Authors: Haese Josiane Maria , Galdi Fernando Caio
Published: September 2020

O objetivo deste artigo é evidenciar a ocorrência de tributação implícita em ativos financeiros do Brasil. O evento estudado nesta pesquisa foi a isenção de Imposto de Renda sobre rendimentos de títulos públicos adquiridos por estrangeiros, benefício dado pela Lei 11.312/06. A análise foi feita sobre o volume total e em segundo momento, sobre quatro títulos específicos: LFT, LTN, NTN-B e NTN-F. A principal hipótese testada é que o volume total de investimento de capital estrangeiro em títulos públicos aumentou após a vigência da Lei 11.312/06. Para o teste, empregou-se a análise de séries temporais, verificando o volume antes e depois do dispositivo legal. Os resultados foram estatisticamente significativos somente para os títulos LTN, NTN-B e NTN-F, situação que pode ser justificada pela forma de remuneração destes dois títulos, que é por cupom de juros semestrais. Os resultados pretendem contribuir para a pesquisa tributária demonstrando a necessidade de maior análise sobre a carga tributária efetiva, pois o tema ainda se encontra limitado, referindo-se somente a carga tributária explícita.

Published: September 2020

Este trabalho buscou analisar as ações desenvolvidas para a promoção da saúde e prevenção no enfrentamento do câncer de colo de útero. Tratou-se de uma pesquisa documental e exploratória do tipo qualitativa. Foram coletados relatos de experiências publicados por profissionais da saúde na Comunidade de Práticas. A análise pautou-se na identificação das principais tendências pedagógicas na educação em saúde: de transmissão de informações, de condicionamento e de problematização crítica. A amostra contou com 15 relatos desenvolvidos predominantemente pelo público feminino, com a tônica no exame preventivo, em unidades de atenção primária à saúde e com ações pontuais no modelo de campanha. A maioria das ações partiu de uma concepção pedagógica de transmissão, visando o repasse de informações acerca da doença e de seu tratamento e prevenção, seguido de ações que se utilizaram do condicionamento, com atividades que visavam alguma recompensa para o objetivo pretendido. A menor parte delas atuaram numa lógica da problematização, visando atuar a partir da perspectiva dialógica-reflexiva. A tímida inserção de atividades com uma abordagem crítica sugere o quanto o ideário da promoção da saúde e da educação popular em saúde merece ser fortalecido nos serviços de saúde.
Interiorização e revolução
Authors: Pacheco Lwdmila Constant
Published: September 2020

O acesso à educação superior no Brasil sempre foi restrito a uma minoria privilegiada. A partir do ano de 2004, o governo federal e os estaduais intensificaram o processo de interiorização do ensino superior. Tal processo de planejamento e implementação contém falhas e atropelos, mas também conquistas e desenvolvimento nas cidades contempladas. Pretendemos, neste trabalho, demonstrar os desdobramentos de tal acesso na vida das comunidades atendidas por meio das narrativas de discentes do curso de Serviço Social, todas do sexo feminino, da cidade de Palmares, em Pernambuco. Utilizamos entrevistas semiestruturadas com seis sujeitos, nos valendo da perspectiva da etnobiografia. A escassez de estrutura física e humana precariza o ensino na região, mas há uma indiscutível transformação da população atendida por conta do impacto da universidade pública e do acesso à educação superior gratuita.
La producción de conocimiento antropológico desde la extensión. Colaboración con poblaciones indígenas de la provincia de Buenos Aires y Norpatagonia, Argentina
Authors: Engelman Juan Manuel , Varisco Sofía , Valverde Sebastían
Published: September 2020

La extensión universitaria, en los últimos años, adquirió una mayor institucionalización gracias a la creación de oficinas de extensión en múltiples universidades nacionales y a su implementación como parte de la currícula en el grado. Estos nuevos escenarios nos interpelan a repensar el lugar que cumple la extensión en relación la investigación y la producción de la teoría antropológica. El presente trabajo tiene por objetivo analizar el vínculo entre dos campos que desde la tradición academicista del campo antropológico se piensan como separados (lo académico y la extensión); desde una mirada que se focaliza en su articulación y considera el contexto de producción del conocimiento como resultado de la colaboración y la demanda intercultural. Llevaremos adelante dicha reflexión la mediante la descripción de tres experiencias de trabajo con pueblos indígenas de la Región Metropolitana de Buenos Aires, la localidad de Carhué —provincia de Buenos Aires— y la región de los lagos en Norpatagonia —provincias de Río Negro y Neuquén.
“Bingo!” Do we have a winner?
Authors: Modell Micah Gideon
Published: September 2020

This design case details my efforts as an instructor to combat the fact that my students were not completingassigned readings. The first step in addressing the issue was recognizing that my students had legitimate reasons for neglecting the assignments and that this was not a situation of me against them. The design solution was based upon the Buzzword Bingo game, a game designed to mock the catchphrases so common in the world of business, and some of the subversive nature of the gamecarried over into the classroom. This lead to students trying to game the system, resulting in tension for me, the instructor, who had to remember that he welcomed these challenges to his authority into the classroom. The increased engagement—which I wanted—required me to become comfortable with the reduced level of control.
Although implementation required minimal technology support and was initially piloted using only a standarddiscussion board, I iterated through multiple rounds of software enhancements to improve ease of use and make it easier to provide quality feedback to my students. These changes resulted in unexpected benefits as they enabled me to perform analytics on the captured responses resulting in a deeper sense of their progress and an ability to tailor my instruction to the student’ needs.

Published: September 2020

This design case introduces a design and development process of using magic performance as a method to facilitate students’ creative design thinking in user-centered design. Magic performance is used not only as a creativity stimulus for facilitating design flexibility but also as a guiding tool for facilitating the design process. Specifically, three design iterations are presented along with design challenges, design solutions, and a discussion of student experiences. A goal of this design case is to inspire other designers to develop similar interventions based on unexplored but meaningful activities, such as magic performance.

TİCARET VE KUR SAVAŞLARININ TÜRKİYE EKONOMİSİ ÜZERİNE MUHTEMEL ETKİLERİ
Authors: ŞANLI Orhan
Published: September 2020

Trump tarifeleri olarak bilinen son ticaret savaşları
dünya ekonomisinde politik değişikliğe yol açmıştır. Özellikle Çin ile beraber
1980’lerden sonra hız kazanan serbest ticaret yerini korumacılığa bırakmaya
başlamıştır. Dolayısıyla korumacılık duvarlarının yükselmeye başlaması küresel
üretimin ve küresel ticaretin değişmesine yol açmaktadır.

Bu çalışmada,
Türkiye’nin ticaret ve kur savaşlarından nasıl etkilendiğinin analizi yapılmıştır.
Çalışmada kullanılan veriler Dünya Bankası, TUİK, TCMB, OECD kurumlarından
alınmıştır. Çalışmada çıkan sonuca göre, ABD’nin ticaret savaşlarını devam
ettirmesi durumunda küresel belirsizlikler nedeniyle Türkiye’de döviz kurları
yükselecektir. Bunun neticesinde ithalat azalırken maliyet enflasyonu
artacaktır. Türkiye’nin ABD ve diğer ülkelere yaptığı ihracat azalacağı gibi,
ihracatın ülke ekonomisine katma değeri de azalacaktır. Analiz sonuçlarına göre
gümrük tarifeleri ile dış ticaret arasında ters yönlü, kurlarla dış ticaret
arasında doğru yönlü bir ilişki vardır. Ayrıca Granger nedensellik sonuçlarına
göre, gümrük tarifeleri ile dış ticaret arasında iki yönlü nedensellik ilişkisi
vardır. Sonuç olarak serbest ticaretten dönülmesi durumunda Türkiye’nin
makroekonomik değerleri olumsuz yönde etkilenecektir.

Agglomeration economies are considered as the driving force behind the development of mega cities and large cities/regions, which are the most successful regions in world economy. According to “New Economic Geography” stream, externalities are approached as static and dynamic externalities. Dynamic externalities are classified as “Marshall (1891) – Arrow (1962) – Romer (1986, 1990) (MAR), Porter (1990) and Jacobs (1969)” by Glaeser et al. (1992). Dynamic externalities come out by the emergence of local knowledge and by strengthening communication among economic actors in the long term. Knowledge spillover also accelerates via strengthening of communication. This paper investigates whether agglomeration externalities affected regional growth in Turkey at the NUTS 3 level during the period 2010 – 2016 by using sectoral employment growth. The results of the study show that effect of MAR (Marshall–Arrow– Romer) externalities is found to be negative as they are in the studies done through the data of most of the countries. It is concluded that unrelated variety (JACOBS) has no effect on employment growth. Coefficients in most of the sectors are seen to be positive in PORTER externalities.

Bu çalışmada, Adıyaman Üniversitesi Beden Eğitimi Spor Yüksek Okulu’ndaki Beden Eğitimi ve Spor Öğretmenliği ve Antrenörlük Eğitimi Bölümlerinde öğrenim gören öğrencilerin, iletişim becerileri ve duygusal zekâ durumlarının incelenmesi amaçlanmıştır. Çalışmanın evrenini 2018-2019 öğretim yıllarında Adıyaman Üniversitesi Beden Eğitimi Spor Yüksek Okulu’nda öğrenim gören Beden Eğitimi ve Spor Öğretmenliği ve Antrenörlük Eğitimi Bölümlerinde amatör ve profesyonel düzeyde bireysel ve takım sporu yapan (1,2,3,4.Sınıf) tüm öğrenciler oluşturmaktadır. Çalışmada veri toplama aracı olarak anket yöntemi kullanılmıştır. Elde edilen veriler SPSS paket programında analiz edilmiştir.

Çalışmanın sonunda, takım sporu yapan sporcuların duygusal zekâ ölçeğinin duyguların kullanımı ve duyguların değerlendirilmesi alt boyutlarında erkek sporcular lehine, takım sporu yapan sporcularda bireysel spor yapan sporculara göre daha yüksek olduğu ve aralarındaki farkında istatistiksel olarak anlamlı olduğu belirtilmiştir. Sporcuların Duygusal zekâ ölçeğinin İyimserlik ve Duyguların Kullanımı boyutları ile İletişim Becerileri Ölçeğinin Uygunluk ve Etkililik Alt Boyutları arasında düşük düzeyde fakat istatistiksel olarak anlamlı pozitif yönlü ilişki tespit edilmiştir.
BRICS ÜLKELERİNDE ETKİNLİK VE TELAFİ EDİCİ ETKİ HİPOTEZLERİNİN GEÇERLİLİĞİNİN TEST EDİLMESİ

Published: September 2020

Piyasalardaki entegrasyonun özellikle 20. yüzyılın sonlarına doğru artmasıyla oluşan ekonomik küreselleşme süreci, ulusal ekonomileri dışa açık hale getirmektedir. Dışa açıklıkta yaşanan artış ise bu ekonomilerin uluslararası risklere maruz kalmalarına neden olmaktadır. Literatürde piyasalarda yaşanan bu ekonomik küreselleşme sürecinin kamu harcamaları üzerinde nasıl bir etki yaratacağı “Etkinlik ve telafi edici etki” hipotezleri bağlamında incelenmektedir. Bu hipotezlerden hangisinin geçerli olduğu, dışa açıklıktan kaynaklı risklerin oluşturabileceği zararların giderilmesi, diğer yandan kamu ve maliye politikalarına yön vermeleri bakımından ekonomiler için önem arz etmektedir. Bu çalışmanın amacı BRICS (Brezilya, Rusya, Hindistan, Çin ve Güney Afrika) ülkelerinde kamu harcamalarının etkinliğini 1991-2018 yıllarına ait verileri kullanarak “etkinlik ve telafi edici etki” hipotezleri bağlamında test etmektir. Kamu harcamalarının gayrisafi yurtiçi hasılaya oranı, gayrisafi yurtiçi hâsıla büyüme hızı ve ticari açıklık için ihracat ve ithalatın gayrisafi yurtiçi hasılaya oranı değişkenlerinin kullanıldığı çalışmada panel veri ekonometrisinden faydalanılmıştır. Çalışmadan elde edilen bulgulara göre, etkinlik hipotezinin geçerli olduğu sonucuna ulaşılmıştır.

It is not obvious to adjust the speed of a conveyor belt so that it is possible to optimize the transport for each piece conveyed even with various studies presented in this area. The complex methodologies that are shown and the many adaptations indicated in these studies may contribute to the low adoption of these configurations. A study made, in this work, from videos of advertisements showing belt conveyor in operating on the factory floor which presented only 44% efficiency. In this work, it was shown, through theoretical studies, a mathematical model that presents the relationship between the speed and the transport capacity of conveyor belts. Based on a model, a graphical method (using templates) has been proposed that helps in choosing the conveyor belt speed for most efficient configurations that can be identified and adopted simply and without many adaptations to the system as a whole.

This research presents a case study related to the management of queues in a supermarket and the problems found in the organization of this process. In order to reduce the time that customers remain in the checkout lines, an analysis of the environment (supermarket) was carried out virtually through the discrete simulation technique, linked to the Arena software. This technique is classified as quantitative because it makes it possible to measure entities and predict the action of the environment in a way that mimics the reality of the queues at the site. Through the simulated scenario, it was possible to identify the flaws in the process and the cause of the queuing. Through the results of the simulation, it was observed that the average length of stay in the queue would be reduced by 88.23% if it contemplates the inclusion of 2 to 3 employees to perform the service. Note that the application of this technique is favorable for problem solving and decision-making, as it reduces the time that customers spend in the queue and optimizes the financial investments allocated in this area.
Economic observatory: proposal of a longitudinal study on the profile of (dis)employment in the Alto Tietê Region
Authors: Filenga Douglas
Published: September 2020

Regional economic data provide myriad possibilities for pursuing projects related to economic growth and development. Specifically, the Economic Observatory consists of the process of elaboration, capture, analysis and distribution of information related to the profile of (dis) employment of labor. From these stages, the production of studies in the form of scientific works and media dissemination, will aim to stimulate the approach of research institutions and the market formed by people who exercise physical and legal activities in the development and practices of actions that allow a better elaboration in resource allocation, either part of government or private enterprise. The procedures started consist of a validation process of the data collection instrument by specialists, pretesting and initial analysis of the applied database. This is a quantitative study, whose database will consist of minimum quantities of 100 used. Larger studies consider clustering as multiple minimum quantities into a large database and proceeding as cross-sectional analyzes of the thirty-seven investigated variables. The expected result is the creation and development of several research groups, as well as generating information on the topic for those interested.

Excavations in marginal areas of the loess uplands in southern Poland have revealed that the northern periphery of the Sandomierz Upland was intensely colonised in the sixth and fifth millennia BC by Linearbandkeramik and Malice Culture Danubian communities. This research suggests that analogous settlement clusters may exist in other marginal regions of the Central European loess belt, previously thought to be uninhabited.

Globally, rock art is one of the most widely distributed manifestations of past human activity. Previous research, however, has tended to focus on the art rather than artists. Understanding which members of society participated in creating such art is crucial to interpreting its social implications and that of the sites at which it is found. This article presents the first application of a method—palaeodermatoglyphics—for the estimation of the sex and age of two later prehistoric individuals who left their fingerprints at the Los Machos rockshelter in southern Iberia. The method has the potential to illuminate the complex socio-cultural dimensions of rock art sites worldwide.
