AVALIAÇÃO DE AMBIENTES VIRTUAIS DE APRENDIZAGEM: UMA REFLEXÃO SOBRE O MODELO INTERACIONISTA E CONSTRUTIVISTA
Authors: Borges Vaz Ribeiro Fernanda , Todescat Marilda , De Linhares Jacobsen Alessandra
Published: April 2018

A avaliação de ambientes virtuais de aprendizagem (AVAS) é realizada por meio de metodologias capazes de analisar a concepção de um AVA, de maneira a assegurar a sua qualidade e eficácia. Nesse sentido, este artigo faz uma análise reflexiva sobre o modelo interacionista/construtivista proposto por Schlemmer e Fagundes (2000) e apresentado na íntegra por Schlemmer (2002), que propõe o uso de parâmetros para avaliação de AVAS, sob o ponto de vista técnico, administrativo, comunicacional-social e didático-pedagógico. A metodologia utilizada foi a pesquisa bibliográfica. Contudo, a análise permitiu verificar que para realizar uma avaliação é essencial conhecer os princípios educacionais que norteiam o design instrucional do sistema, analisar suas múltiplas ferramentas e funcionalidades, e identificar como os usuários estão fazendo uso dos recursos do AVA, no intuito de verificar suas necessidades e ampliá-los.

Authors: Atz Dafne
Published: April 2018

O estudo dos conceitos de área e perímetro pode gerar dúvida para os alunos do Ensino Fundamental. Com o intuito de esclarecer essas noções, buscou-se uma atividade que permitisse trabalhar com esses conceitos de uma maneira mais visual, possibilitando expandir, através do Teorema de Pick, a ideia de área dos polígonos trabalhados no 6° ano do Ensino Fundamental de uma escola particular, a saber quadrados e retângulos e decomposições nestes polígonos. Foi utilizado para isso o Geoplano Online que proporcionou uma manipulação mais ágil de polígonos irregulares, onde os alunos enxergaram os conceitos envolvidos com mais facilidade, possibilitando a melhor compreensão dos mesmos. Sendo assim, este artigo busca trazer uma proposta de atividade investigativa elaborada para uma turma de 6° ano, enunciando o Teorema de Pick, assim com algumas de suas aplicações.

Authors: Stormowski Vandoir , Alice Gravina Maria , Valdeni de Lima José
Published: April 2018

apesar do desenvolvimento das tecnologias digitais em diversas áreas, estudos apontam que estes recursos ainda são utilizados de forma insuficiente ou precária no processo de ensino e aprendizagem de matemática. Neste cenário, o artigo apresenta um estudo em andamento com o objetivo de qualificar a apropriação da tecnologia por parte dos professores de matemática. O estudo se fundamenta na teoria da abordagem instrumental (Rabardel) no que se refere ao processo de apropriação de um artefato (software GeoGebra) e na teoria dos registros de representação (Duval) no que diz respeito à articulação do conhecimento matemático através do uso de representações dinâmicas. A partir deste enfoque, são apresentadas estratégias de formação que possam qualificar o processo de apropriação da tecnologia pelos professores de matemática.
Transformar la heterogeneidad en recurso comparativo: variaciones etnográficas e históricas en los sentidos de homosexualidad y familia
Authors: Vespucci Guido
Published: April 2018

El artículo consiste en una reflexión sobre los recursos teórico-metodológicos que permitieron destrabar el trabajo de campo y redefinir el problema de investigación de mi tesis doctoral, el cual pasó del estudio focalizado de familias homoparentales a la exploración de variaciones etnográficas e históricas sobre las concepciones de homosexualidad y familia en personas y movimientos gay-lésbicos de la Argentina contemporánea. Así, retoma la propuesta de Fredrik Barth sobre la búsqueda de variaciones del mismo objeto, para convertir la dispersión de datos en un recurso comparativo que atienda la heterogeneidad en las maneras de comprender las nociones de homosexualidad y familia según distintos momentos históricos, escenarios sociales y perfiles de actor. Las comparaciones son repensadas respecto al uso de la antropología social clásica –elaboradas entre culturas luego de las descripciones etnográficas– para emplearlas como recurso de construcción de conocimiento en el proceso mismo de investigación, desdibujando la idea de una (sub)cultura homosexual homogénea, estática e integrada que habilitaba afirmaciones esencialistas sobre su auténtico modo de vida en el contexto de los debates por el reconocimiento social y legal de algunas de sus formas familiares. Palabras clave: Método comparativo. Variaciones de sentido. Homosexualidad. Familia.Transforming heterogeneity into a comparative resource: ethnographic and historical variations in the meanings of homosexuality and familyAbstractThis article is a reflection on the theoretical and methodological resources that allowed me to overcome the fieldwork and to redefine the problem of my PhD research, that changed from the focused study of homo-parental families to the exploration of ethnographic and historical variations of the conceptions of homosexuality and family in persons and gay-lesbian movements of contemporary Argentina. In this way, it picks up on Fredrik Barth's idea about searching for variations of the same object in order to turn the dispersion of information into a comparative resource that analyzes heterogeneity in the ways of understanding the notions of homosexuality and family according to different historical moments, social scenes and actor's profiles. The comparisons are picked up in relation to the use given by classic social anthropology –elaborated between cultures after the ethnographic descriptions– to use them as a source of construction of knowledge in the process of research, dismantling the idea of a homosexual homogeneity, a static and integrated (sub)culture that enabled essentialist affirmations on its authentic way of life in the context of the discussions for social and legal recognition of some of its familiar forms. Key words: Comparative method. Variations of meaning. Homosexuality. Family.
Casamento fantasma? - A presença dos ancestrais através de imagens
Authors: Azevedo Aina
Published: April 2018

Por meio de fotografias tiradas pela família Kubheka e por mim, este artigo discute a presença dos ancestrais na vida ritual e cotidiana dessa família, falante de isiZulu, na África do Sul. Com o fim do apartheid e a implementação do programa de Land Reform na democracia, os Kubheka foram contemplados com uma fazenda em que finalmente passaram a viver sem ameaças. Ali, tiveram a oportunidade de realizar o umabo - prestação matrimonial que compõe o casamento zulu. Embora a noiva já tivesse falecido há anos, durante o umabo ela devereria ser conduzida à fazenda em que os Kubheka vivem atualmente. Para tanto, uma neta irá protagonizar a avó falecida e parentes consanguíneos se passarão por afins, além de casas atuais fazerem as vezes de casas pretéritas, assim, todos, vivos e ancestrais poderão estar com propriedade na fazenda que finalmente conquistaram.Palavras-chave: Casamento. Ritual.  Reforma Agrária.  Zulu.  África do Sul.Ghost Marriage - The ancestor’s presence through the images AbstractThrough photographs taken by the Kubheka family and by myself, this article discusses the presence of the ancestors in the ritual and ordinary life of this family - who speaks isiZulu - in South Africa. With the end of the apartheid era and the development of the Land Reform in the democracy, the Kubheka  family received a farm where they finally could live safely. There they had the opportunity to realize the umabo - one of the matrimonial exchanges that produces the zulu marriage. Besides the fact that the bride had passed away a long time ago, she was supposed to be guided to the new farm where the Kubhekas were living presently. Therefore, a granddaughter will have to stand on the behalf of the late grandmother and consanguine relatives will substitute the in law relatives. Moreover, the actual houses will have to represent the former ones. Consequently, all people involved - living and dead - will be able to be in the farm conquered by the Kubhekas.Key words: Marriage. Wedding Ritual.  Land Reform. South Africa. Zulu.

Hyperspectral Modeling of Material Appearance: General Framework, Challenges and Prospects
Authors: Baranoski Gladimir
Published: April 2018

The main purpose of this tutorial is to address theoretical and practical issues involved in the development of predictive material appearancemodels for interdisciplinary applications within and outside the visible spectral domain. We examine the specific constraints and pitfalls found in each of the key stages of the model development framework, namely data collection, design and evaluation, and discuss alternatives to enhance the effectiveness of the entire process. Although predictive material appearance models developed by computer graphics researchers are usually aimed at realistic image synthesis applications, they also provide valuable support for a myriad of advanced investigations in related areas, such as computer vision, image processing and pattern recognition, which rely on the accurate analysis and interpretation of material appearance attributes in the hyperspectral domain. In fact, their scope of contributions goes beyond the realm of traditional computer science applications. For example, predictive light transport simulations, which are essential for the development of these models, are also regularly beingused by physical and life science researchers to understand andpredict material appearance changes prompted by mechanisms which cannot be fully studied using standard ``wet'' experimental procedures.For completeness, this tutorial also provides an overview of such synergistic research efforts and in silico investigations, which are illustrated by case studies involving the use of hyperspectral material appearance models.
O conhecimento secreto de David Hockney e as múltiplas janelas de tempo nos desenhos de Jandira Lorenz
Authors: Makowiecky Sandra , Oliveira Vanessa Bortucan de
Published: April 2018

Pensando na relação “leitura visual: arte, mídia e cotidiano”, entre ciência e imagem e nos processos de produção de imagens com problemas estéticos e de representação, alguns artistas nos chamam a atenção, pois utilizam a própria arte como fonte de aprendizagem, em procedimento científico, de forma mais explícita. Um deles é David Hockney, que com o livro "O Conhecimento Secreto", nos explica como tenta redescobrir as técnicas perdidas dos grandes mestres, mostrando seu fascínio pela pintura, pelo mágico universo surgido da capacidade e necessidade que tem o homem de representar a realidade e de inventá-la. O outro é a artista plástica Jandira Lorenz, professora de história da arte, que em sua produção revela sobrevivências, sintomas de sua experiência com os estudos em arte. Este artigo visa construir um pensamento em relação à montagem de tempos históricos diversos nas obras da artista Jandira Lorenz com o livro de David Hockney que contribuiu com a possibilidade de estabelecer um ponto de convergência quanto às características de multiplicidades e particularidades na compreensão das imagens vistas por janelas múltiplas na recente pesquisa do acervo completo de desenhos de Jandira Lorenz. Ao enfocar a ligação desses dois artistas com a arte e a ciência, sobretudo, enfatizamos o valor da pesquisa artística.
Does ownership structure improve credit ratings?
Authors: AlHares Aws , King David , Ntim Collins , Byrne Ron
Published: April 2018

This study seeks to examine the impact of Block Ownership structure on Credit Ratings in OECD countries. This research seeks to contribute to the extant literature by exploring the effects of Corporate Governance (CG) mechanisms on corporate credit ratings. The study uses a panel data of 200 companies from Anglo American and European countries between 2010 and 2014. The ordinary least square regression is used to examine the relationships. Additionally, to alleviate the concern of potential endogeneity, we use fixed effect regression, two-stage least squares using instrumental variables. The results show there is a negative and significant relationship between block ownership and credit ratings, with a greater significance among Anglo American countries than among European countries. The rationale for this is that Anglo-American system gives preferential treatment to individual shareholders and its accounting tradition leads to a decline in risk and increase in credit ratings. The result is consistent with the multi-theoretical framework predictions derived from the agency and stewardship theories. Future research could investigate credit ratings using other credit rating agencies, selecting a larger sample that includes small, mid-size and large companies. This paper extends, as well as contributes to extant CG literature by offering new evidence on the effect of block ownership on credit ratings between two different traditions. This will be explored by employing firm-level CG mechanisms by accounting for control variables. The findings will help regulators and policymakers in OECD countries in evaluating the adequacy of current CG reforms to prevent management misconduct and scandals.
Habilidades digitales en jóvenes que ingresan a la universidad: realidades para innovar en la formación universitaria / Digital skills in young people entering the university: realities to innovate in university education
Authors: González Bello Edgar Oswaldo
Published: April 2018

Los estudiantes de hoy en día pertenecen a una generación desarrollada alrededor de entornos digitales; son jóvenes —no todos— que pasan su mayor tiempo utilizando dispositivos tecnológicos. En atención a esta realidad, las tecnologías de la información y la comunicación (TIC) han sido incorporadas a los espacios universitarios a través de modificaciones para que estos jóvenes puedan aprender de una mejor manera. Al respecto, este estudio analiza el nivel de desarrollo de las habilidades digitales que los propios alumnos consideran los identifica al ingresar a sus estudios universitarios, así como otros aspectos que han propiciado este aprendizaje, a través de la aplicación del método cualitativo en 18 estudiantes de nuevo ingreso en la Universidad de Sonora, México. Los resultados muestran que es posible identificar que las TIC se incorporan a la vida de los jóvenes estudiantes en diferentes caminos e inician su preparación para desarrollar habilidades tecnológicas, algunos más pronto que otros y de manera diversa a través de los distintos niveles educativos. También que existen quienes desde temprana edad tienen contacto con dispositivos tecnológicos, conviviendo en un contexto en donde las computadoras e Internet llegan a casa como una necesidad. Se concluye que las TIC y su empleo en el contexto universitario debe obligar a repensar las formas en que se realizan los procesos de enseñanza y aprendizaje, asumiendo que las nuevas generaciones poseen habilidades digitales, si bien no todos sus integrantes, ni de la misma forma.
O ensino híbrido: processo de ensino mediado por ferramentas tecnológicas
Authors: Bertholdo Neto Emílio
Published: April 2018

As universidades têm encontrado um novo perfil de aluno ocupando suas cadeiras, definido como membros da Geração Y. Esta geração é constituída, de acordo com alguns autores, por indivíduos nascidos aproximadamente entre os anos de 1980 e 2000 e possuem perfil mais questionador, com rápido acesso à informação devido aos grandes avanços tecnológicos e relacionamentos pautados no ambiente virtual. Considerando tais fatores, as metodologias tradicionais de ensino-aprendizagem demonstram-se pouco efetivas para ensinar os membros dessa geração em comparação com os membros de gerações passadas. Este estudo visa entender algumas questões acerca da metodologia de ensino híbrido, conhecida também como blended learning. Tal metodologia é caracterizada pela união entre ensino presencial, por meio de projetos e resolução de problemas, e estudo on-line, alterando a dinâmica professor-aluno, onde o professor assume o papel de mediador do conhecimento, e não o de portador, como é caracterizado no ensino tradicional.

PENGARUH PEMBERIAN DUA JENIS ZAT PENGATUR TUMBUH ALAMI TERHADAP PERTUMBUHAN SEEDLING MANGGIS (Garcinia mangostana L.)
Authors: Warohmah Mawadah , Karyanto Agus , Rugayah Rugayah
Published: April 2018

Manggis (Garcinia mangostana L.) merupakan salah satu tanaman buah asli tropis yang memiliki laju pertumbuhan pada saat pembibitan yaitu pada umur < 2 tahun sangat lambat. Hal ini disebabkan sistem perakarannya terbatas, sehingga penyerapan air dan unsur hara rendah. Salah satu upaya yang dapat dilakukan untuk mempercepat pertumbuhan bibit manggis yaitu dengan pemberian zat pengatur tumbuh. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi ekstrak kecambah yang menghasilkan pertumbuhan terbaik terhadap pertumbuhan seedling manggis, pengaruh pemberian ekstrak daun kelor terhadap pertumbuhan seedling manggis, dan pengaruh pemberian ekstrak kecambah pada masing-masing pemberian ekstrak daun kelor dalam mempengaruhi pertumbuhanseedling manggis. Penelitian ini dilakukan pada bulan November 2016 - Januari 2017 di rumah kaca gedung Hortikultura Universitas Lampung. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan perlakuan faktorial yang terdiri dari dua faktor (3 x 2). Faktor pertama: taraf konsentrasi ekstrak kecambah (K) yang terdiri: 0 g l -1 (k 0 ), 100 g l -1 (k 1 ), dan 200 g l -1 (k 2 ). Faktor kedua adalah ekstrak daun kelor (D) tanpa ekstrak daun kelor 0 g l -1 (d 0 )dan ekstrak daun kelor 100 g l -1 atau 20% (d 1 ). Hasil penelitian menunjukkan bahwa pemberian ekstrak kecambah 0 g l -1 ,100 g l -1 dan 200 g l -1 dan ekstrak daun kelor 0 g l -1 dan 100 g l -1 tidak berpengaruh nyata pada semua variabel pengamatan pertumbuhan seedling manggis. Walaupun tidak berbeda nyata, kombinasi perlakuan ekstrak kecambah 100 g l -1 dan ekstrak daun kelor 100 g l -1 berpotensi memiliki pertumbuhan lebih baik yang dapat dilihat dari penambahan jumlah daun dengan rata- rata 1,78 dan jumlah akar sekunder dengan rata-rata 21 helai.

Pengolahan tanah merupakan kegiatan yang dilakukan untuk penyiapan lahan dengan tujuan memperbaiki sifat fisik tanah. Pada prinsipnya pengolahan tanah ada dua yaitu konvensional/intensif dan konservasi/minimum. Pengolahan tanah yang dilakukan secara intensif dapat menimbulkan degradasi. Penyebab degradasi yang paling utama adalah erosi. Erosi akan membawa partikel tanah yang mengandung unsur hara dan bahan organik. Penelitian ini dilaksanakan pada Oktober 2016 sampai Februari 2017 di Laboratorium Lapang Terpadu dan Laboratorium Ilmu Tanah, Fakultas Pertanian, Universitas Lampung. Penelitian ini bertujuan untuk mengetahui pengaruh sistem olah tanah dan pemberian herbisida terhadap kehilangan unsur hara (N, P, K, Ca, Mg) dan bahan organik akibat erosi pada pertanaman jagung. Rancangan yang digunakan yaitu Rancangan Acak Kelompok Lengkap (RAKL) dengan dua faktor perlakuan yaitu sistem olah tanah dan pemberian herbisida denganempat kali ulangan. Hasil analisis ragam menunjukkan bahwa N-total, P-tersedia, K-dd, Ca-dd, dan C-organik tidak berbeda nyata pada pengolahan tanah, pemberian herbisida, maupun interaksi keduanya dalam sedimen akibat erosi, sedangkan Mg- dd berbeda nyata pada perlakuan pengolahan tanah. Pada olah tanah minimum konsentrasi Mg-dd yang hilang sebesar 0,8187 me per 100 g dan olah tanah intensif 0,8013 me per 100 g, sehingga kehilangan Mg-dd pada olah tanah minimum lebih besar dari olah tanah intensif.

Authors: Aguiar Roberto , Espinosa A , Carrión J , Zambrano V.
Published: April 2018

Después del terremoto del 16 de abril de 2016, que tuvo una magnitud de  7.8; se realizó estudios geofísicos en 17 lugares de la ciudad de Bahía de Caráquez, para emitir un diagnóstico sobre la vulnerabilidad sísmica de algunos edificios; 13 de los 17 suelos analizados clasificaron como perfiles tipo “C” y 4 como tipo “D”. Pero la velocidad de la onda de corte de los 4 sitios con suelo “D”, es alta, de tal manera que se puede indicar que los 17 lugares donde se encontraban y se encuentran estructuras importantes eran suelos resistentes, de acuerdo a la clasificación de la Norma Ecuatoriana de la Construcción de 2015. Entonces.En este artículo, se presenta la relación que existe entre la Velocidad de la Onda de Corte en los primeros 30 metros, con la frecuencia dominante del suelo y con la amplitud del Espectro de Fourier asociada a la frecuencia dominante, de los suelos de Bahía de Caráquez. De igual manera se compara estos parámetros geofísicos con los resultados de estudios similares realizados con dos bases de datos; la primera con sismos registrados en Japón y la segunda con sismos de la base de datos NGA-West 2.Finalmente se concluye que en la clasificación de los suelos de la NEC-15 basada más en la Velocidad de la Onda de Corte debe ser complementada con la inclusión del período de vibración del suelo o con la amplitud máxima del Espectro de Fourier.

Cryptocurrency is considered as a means of payment, property, and asset. The author identifies the following approach-es of the states to the legal regulation of this eco-nomic and legal phenomenon: 1) the legislation of countries is neutral toward this phenomenon and does not regulate it; 2) the new legislation that is adopted regulates the turnover of cryptocurrency and promotes its development; 3) the scope under review is regulated within the traditional legal institutions; 4) there is a ban on the use of cryptocurren-cy in the civil and financial field. The author investigates the possible effects of the formal approval to carry out digital currency transactions. The case studies for declaring cryptocurrency exchanges bankruptcy are discussed.
From voluntary private to mandatory state governance in Indonesian forest certification: Reclaiming authority by bureaucracies
Authors: Wibowo Agung , Giessen Lukas
Published: April 2018

Forest certification has been introduced by non-state actors as a voluntary and market-based instrument addressing forest problems, which state policies failed to resolve. Lately, however, state-driven forest-related certification schemes can be observed, e.g. in Indonesia, through the EU FLEGT-VPA negotiation process. It is argued, specific state agencies in a struggle for power and authority develop mandatory certification schemes which are directly competing with private ones. Before this background, the aims of this study are: (i) describing the current trend from voluntary private to mandatory state certification schemes in Indonesia, (ii) mapping the main actors involved in certification politics, and (iii) explaining this trend with the interests of the main actors. The results confirm a trend from voluntary private to mandatory state-driven certification of forest management. The Ministry of Forestry, the Ministry of Trade, the Ministry of Industry, wood producer and processing associations, European Union, local funding organizations, environmental organizations, certification bodies and international buyers are detected as the main coalitions and actors in the certification politics. The stronger coalition develops a mandatorily-timber legality verification system as strategies to counter their voluntary private competitor schemes.
Transforming forest landscape conflicts: the promises and perils of global forest management initiatives such as REDD+

Implementation of Reducing Emissions from Deforestation and Forest Degradation (REDD+) is designed to relieve pressure on tropical forests, however, many are concerned that it is a threat to the rights of forest communities. These potential risks need serious attention as earlier studies have shown that the Asia-Pacific region is a forest conflict hotspot, with many economic, environmental and social implications at global (e.g. climate change) to local levels (e.g. poverty). Drawing on an analysis of nine case studies from four countries (Cambodia, Myanmar, Nepal and Vietnam) this paper examines why and how REDD+ can be a driver for forest conflict and how it also has the potential to simultaneously transform these conflicts. The analytical framework, “sources of impairment”, applied in the study was developed to increase understanding and facilitate the resolution of forest landscape conflicts in a sustainable manner (i.e. transformation). The main findings are that REDD+ can be a source of conflict in the study sites, but also had transformative potential when good practices were followed. For example, in some sites, the REDD+ projects were sources of impairment for forest communities by restricting access to forest resources. However, the research also identified REDD+ projects that enabled the participation of traditionally marginalized groups and built local forest management capacities, leading to strengthened tenure for some forest communities. Similarly, in some countries REDD+ has served as a mechanism to pilot Free, Prior and Informed Consent (FPIC), which will likely have significant impacts in mitigating conflicts by addressing the sources at local to national levels. Based on these findings, there are many reasons to be optimistic that REDD+ can address the underlying causes of forest landscape conflicts, especially when linked with other governance initiatives such as Forest Law Enforcement, Governance and Trade – Voluntary Participation Agreements (FLEGT-VPA).

Published: April 2018

Background: Learning Management Systems (LMS) represent one of the main technology to support learning in HE institutions. However, every educational institution differs in its experience with the usage of these systems. South East European University’s LMS experience is longer than a decade. From last year SEE – University is adopting Google Classroom (GC) as an LMS solution.

Objectives: Identifying factors which encourage LMS activities, with special emphasis on SEEU, might be of crucial importance for Higher Education academic leaders as well as software developers who design tools related to fostering LMS.

Methods/Approach: This paper introduces new approach of investigating the usage of LMS, i.e. identifying the determinants of increasing usage of LMS activities, by conducting empirical analysis for the case of SEEU. We apply appropriate estimation technique such as OLS methodology.

Results: Using SEEU Usage Google Classroom Report & Analysis Data for spring semester (2016–2017) and winter semester (2017–2018) - SUGCR dataset 2017, we argue that (i) LMS activities are affected by demographic characteristics and (ii) the students’ LMS usage is affected by level and resources of instructors’ LMS usage.

Conclusions: The empirical results show positive relationship between student and instructors’ LMS usage.
Research Activities and their Relation to Economic Performance of Regions in the European Union

Published: April 2018

Background: The intensity of innovation could often be crucial for further economic development of the regions. Science and technology are often seen as the key factor supporting innovation in the regions. Furthermore, we can assume that higher intensity of research activities could lead to better economic performance.

Objectives: Research aims to examine the link between the economic performance of the region and the intensity of science and technology activities, proxied by the share of employees in science and technology.

Methods/Approach: The analysis is based on panel data for NUTS2 regions of the European Union (EU) member states. We conducted correlation analysis, panel Granger causality tests and regression analysis.

Results: Our results suggest the existence of a significant positive correlation between GDP per capita and the share of employees in science and technology. Moreover, the regions with a higher intensity of science and technology activities are mostly characterized by relatively low unemployment rates.

Conclusions: Research activities are positive correlated with regional GDP and negatively correlated with unemployment. However, increasing the share of employment in science and technology beyond a certain turning point would not lead to any further positive effects on regional economic performance.
The Effect of Government Subsidy on Non-Technological Innovation and Firm Performance in the Service Sector: Evidence from Germany
Authors: Basit Shoaib Abdul , Kuhn Thomas , Ahmed Mumtaz
Published: April 2018

Background: To enhance the innovation activities at the firm level, government subsidies plays an important role.

Objectives: The objective of the study is to explore whether firms in service sector that receive government subsidies engage more in marketing and organizational innovation activities than their counterparts. Second, focusing on the subsidized firms in the service sector, the impact of innovations (marketing as well as organizational) on firm performance—measured as the probability of submitted copyright applications by firms, has been analyzed.

Methods/Approach: The propensity score matching approach and probit model have been used to analyze the innovation activities of subsidized and non-subsidized firms. The empirical analysis is based on the micro level data from Mannheim Innovation Panel, covering the Community Innovation Survey of 2011.

Results: Empirical results show that public subsidy has a significant positive effect on marketing and organizational innovation. In addition, within the firms that have received government subsidy, the impact of only marketing innovation is found to be significant on firm performance.

Conclusions: These findings employ that subsidized firms are more likely to perform better than their counterparts. Furthermore, public subsidy programs increase the probability of applying for a copyright in small and medium firms.

A amputação de membros é um procedimento reconstrutor, porém, altamente invasivo, podendo causar abalos não apenas orgânicos, mas psíquicos.Partindo disso, investigou-se, por meio de uma pesquisa qualitativa e de um aporte teórico psicanalítico, como os sujeitos amputados vivenciam amudança corporal. Foram entrevistados 9 sujeitos submetidos à cirurgia de amputação em um hospital público do Rio Grande do Sul. Compreendeu-seque a amputação assumiu um caráter traumático para esses sujeitos, provocando uma ruptura nos alicerces simbólicos constitutivos de cada um erepercutindo diretamente na imagem corporal e em seu narcisismo. Diante disso, mostrou-se necessário o processo de reintegração corporal que exigeum trabalho de luto pelo membro amputado e pela imagem corporal mantida até o momento da cirurgia.
