El cine sin encuadre: propuesta de Escala de Implicación Narrativa en Realidad Virtual
Authors: Bonilla Diego , Galán Fajardo Helena
Published: May 2020

La posibilidad de grabar en 360° ha despertado el interés de emprendedores e investigadores en torno a las potenciales facultades narrativas de la realidad virtual en distintos ámbitos. No obstante, aún quedan algunas cuestiones que no han sido lo suficientemente confirmadas, como el mayor nivel de implicación narrativa del espectador en esta nueva forma de narrar. Para suplir esa carencia, esta investigación presenta el diseño de un análisis experimental planteado en distintas fases. Se trata de un proyecto piloto de tipo cuantitativo-cualitativo basado en la escala mneq (Busselle & Bilandzic, 2009) que permite evaluar y comparar la experiencia de visionado de un relato narrativo mediante presentación en realidad virtual y diferentes tipos de pantallas bidimensionales a un mínimo de 100 personas divididas en grupos experimentales. Bajo el supuesto de que cada tratamiento o cada tecnología (variable independiente) tiene diferentes impactos en la implicación narrativa (variable dependiente) del espectador, se pretende analizar la empatía (ep), simpatía (s), toma de perspectiva cognitiva (cp), pérdida de tiempo (lt), pérdida de auto- conciencia (ls), presencia narrativa (np), participación narrativa (ni), distracción (d), facilidad de acceso cognitivo (ec) y realismo narrativo (nr). Para ello se incluyen cuatro tipos de análisis diferentes (estadístico, de varianza, de observación, de preguntas abiertas). Ofrecemos un nuevo modelo de análisis de elaboración propia para obras de realidad virtual cinematográficas completas en español. El diseño experimental busca establecer un modelo de investigación integral con el fin de debatir si la realidad virtual ofrece, como se cree, mayor envolvimiento (engagement).
Pós-fotorreportagem e os desafios das novas narrativas audiovisuais
Authors: Porto Reno Denis
Published: May 2020

A fotorreportagem é uma modalidade que se ressignificou com a chegada dos ambientes digitais navegáveis, assim como a própria fotografia, redefinida por Fontcuberta (2016) como pós-fotografia. Com base nesta problemática, este artigo oferece resultados qualitativos referentes a uma crescente forma de produção narrativa jornalística, que contempla conteúdos audiovisuais e fotográficos, em uma composição essencialmente imagética, denominada a partir deste trabalho como pós-fotorreportagem. Trata-se de um artigo resultante de investigação aplicada, que tem apresenta a análise da obra Prismas de Marrakech, desenvolvida especificamente para o desenvolvimento desta pesquisa. Como conclusão, apontou-se em direção das definições do conceito de pós-fotorreportagem, que reconfigura a própria produção de reportagens imagéticas jornalísticas. Espera-se, com os resultados aqui apresentados, que o formato possa ser continuamente estudado, dada a sua capacidade cognitiva de oferecer ao usuário uma intensa experiência narrativa com base na imagem. Também espera-se, com a conclusão desta pesquisa, que novos estudos relacionados à fotografia possam ser desenvolvidos, contemplando o crescente espaço ocupado pela reportagem jornalística, cada vez mais presente no cotidiano midiático.
Fire Code Inspection and Compliance: A Game-Theoretic Model Between Fire Inspection Agencies and Building Owners
Authors: Agarwal Puneet , Hunt Kyle , Srinivasan Shivasubramanian , Zhuang Jun
Published: May 2020

Fire-code inspection and compliance are among the highest priorities for fire-inspection agencies to reduce the loss of life and property that can result from fire incidents. Requirements for code compliance and inspection vary throughout towns and states within the United States, and building owners who violate these codes can be penalized via fines and mandated compliance measures. To the best of our knowledge, no previous study has investigated the strategic behavior of players in a fire-code inspection process. This paper fills the gap by presenting the game-theoretic approach to modeling building owners’ behaviors with respect to fire-code compliance and the inspection strategies of fire-inspection agencies. Both a decentralized model (sequential game in which the fire-inspection agency moves first) and a centralized model (simultaneous game controlled by one central decision maker) are developed to identify the best inspection strategies for the agency and the best compliance strategies for the building owner. This study provides prescriptive insights that can enable policymakers to improve fire-code compliance and inspection by identifying the conditions that motivate the players to participate positively in the inspection and compliance processes. Numerical sensitivity analyses of the equilibrium strategies and the expected losses of the players are provided, along with a comparison of the results between the decentralized and centralized models.
Capacity Rights and Full-Cost Transfer Pricing
Authors: Dutta Sunil , Reichelstein Stefan
Published: May 2020

This paper examines the theoretical properties of full-cost transfer prices in multidivisional firms. In our model, divisional managers are responsible for the initial acquisition of productive capacity and the utilization of that capacity in subsequent periods, once operational uncertainty has been resolved. We examine alternative variants of full-cost transfer pricing with the property that the discounted sum of transfer payments is equal to the initial capacity acquisition cost and the present value of all subsequent variable costs of output supplied to a division. Our analysis identifies environments where particular variants of full-cost transfer pricing induce efficiency in both the initial investments and the subsequent output levels. Our findings highlight the need for a proper integration of intracompany pricing rules and divisional control rights over capacity assets.

The Role of Problem Specification in Crowdsourcing Contests for Design Problems: A Theoretical and Empirical Analysis
Authors: Jiang Zhaohui (Zoey) , Huang Yan , Beil Damian R.
Published: May 2020

Problem definition : This paper studies the role of seekers’ problem specification in crowdsourcing contests for design problems. Academic/practical relevance : Platforms hosting design contests offer detailed guidance for seekers to specify their problems when launching a contest. Yet problem specification in such crowdsourcing contests is something the theoretical and empirical literature has largely overlooked. We aim to fill this gap by offering an empirically validated model to generate insights for the provision of information at contest launch. Methodology : We develop a game-theoretic model featuring different types of information (categorized as “conceptual objectives” or “execution guidelines”) in problem specifications and assess their impact on design processes and submission qualities. Real-world data are used to empirically test hypotheses and policy recommendations generated from the model, and a quasi-natural experiment provides further empirical validation. Results : We show theoretically and verify empirically that with more conceptual objectives disclosed in the problem specification, the number of participants in a contest eventually decreases; with more execution guidelines in the problem specification, the trial effort provision by each participant increases; and the best solution quality always increases with more execution guidelines but eventually decreases with more conceptual objectives. Managerial implications : To maximize the best solution quality in crowdsourced design problems, seekers should always provide more execution guidelines and only a moderate number of conceptual objectives.
Information Disclosure and Pricing Policies for Sales of Network Goods
Authors: Hu Ming , Wang Zizhuo , Feng Yinbo
Published: May 2020

Amazon and Apple, which sell tablet devices, have adopted different implicit information policies and developed distinct “reputations” about their tablets’ sales volume release. With Amazon, “even a number as basic, and presumably impressive, as how many Kindle e-readers the company sells is never released.” With Apple, iPhone and iPad sales numbers are always released, even if they are disappointing. In the paper “Information Disclosure and Pricing Policies for Sales of Network Goods,” the authors study the sales information release policy, disclosure versus nondisclosure, for selling network goods subject to market size uncertainty. They identify two countervailing effects, a prodisclosure “Matthew effect” and an antidisclosure saturation effect, that drive the firms’ sales information disclosure policies. In addition, the authors also study the situation where the firm can decide on an all-or-nothing information disclosure policy together with endogenized prices, including state-independent pricing, contingent preannounced pricing, and contingent pricing without commitment.

Learning from Digital Failures? The Effectiveness of Firms’ Divestiture and Management Turnover Responses to Data Breaches
Authors: Say GuiDeng , Vasudeva Gurneeta
Published: May 2020

We examine whether firms learn from digital technology failures in the form of data breach events, based on the effectiveness of their failure responses. We argue that firms experiencing such technological failures interpret them broadly as organizational problems, and undertake unrelated divestitures and top management turnover to achieve better standardization and to remove dysfunctional routines. We test our hypotheses on unrelated subsidiary divestitures and chief technology officer (CTO) turnovers undertaken by 8,760 publicly traded U.S. firms that were at risk of experiencing data breaches involving the loss of personally identifiable information during the period 2005–2016. We find that data breaches significantly increase the hazard of unrelated divestitures and CTO turnover, and that these failure responses are sensitive to firms’ aspiration-performance feedback. However, whereas unrelated divestitures reduce the reoccurrence of data breaches, CTO turnover has no significant effect. Our findings suggest a corrective role of unrelated divestitures for failure learning, and the symbolic nature of CTO turnover as a failure response. Our study unpacks failure learning that hitherto has been inferred from a firm’s own failure experience and industry-wide failures, and highlights the interplay between the digital and nondigital components of a firm in the understudied context of data breaches.

A análise jurídica da política econômica aplicada ao Programa Minha Casa, Minha Vida: um estudo de caso de Brasília (2014-2017).
Authors: Moreira Camilla Fernandes , Castro Marcus Faro de
Published: May 2020

O Programa Minha Casa, Minha Vida (PMCMV) completa, em 2019, dez anos de execução e, embora seja reconhecidamente o maior programa habitacional já implementado no País, seu futuro é, atualmente, incerto. O histórico da atuação do poder público na solução de problemas relacionados à moradia, remonta, no País, programas sociais paliativos, pontuais, desarticulados e ineficazes. A análise realizada busca incorporar atributos muito mais amplos que o mero quantitativo de unidades produzidas por faixas de renda, realizando uma pesquisa empírica voltada também para a verificação de elementos outros, tais como localização e disponibilidade de modais de transporte, a existência de equipamentos sociais, a estrutura física/dimensão dos imóveis e reflexos do contexto político-econômico. A metodologia da Análise Jurídica da Política Econômica (AJPE), empregada nesse trabalho, tornou esse exame possível, tanto em termos de produção de um Índice de Fruição Empírica por Faixa de Renda (Análise Posicional), como para fins de identificar alguns efeitos que indicadores macroeconômicos podem ter sobre a fruição desse mesmo direito à moradia. Os resultados são, infelizmente, desalentadores, há muitas distorções a serem enfrentadas pelo PMCMV, principalmente quanto à distribuição de imóveis por faixa de renda e a viabilidade de fruição do direito à moradia nas condições dispostas.
Da mobilidade de pessoas na Europa: imigração regular e desenvolvimento econômico
Authors: Guimarães Claudio Alberto Gabriel , Torres Bruno Miguel Fena
Published: May 2020

O continente europeu sempre foi uma região de acolhimento de refugiados e de migrantes, constituindo-se, assim, numa região com especial atratividade para os fluxos migratórios. A mobilidade internacional de pessoas não é um fenômeno recente, sucedendo em todo o mundo e há vários séculos. Na última década, a Europa tem sido marcada pela intensificação de fluxos migratórios, principalmente do Médio Oriente e da África Subsaariana, resultante de conflitos armados e de perseguições. Em tal contexto, intenta-se investigar se este movimento de pessoas, indissociável da perspectiva econômica, pode afetar de forma negativa e generalizada o espaço europeu ou, em sentido contrário, se pode se constituir em benéfico, inclusive, por se constituir como fator de rejuvenescimento de um continente envelhecido demograficamente. É nesta abordagem metodológica quali-quantitativa, a partir de fontes bibliográficas, que se foca a importância da migração, com especial incidência na caracterização da população requerente de asilo, na mitigação da tendência demográfica e processo de envelhecimento populacional no mercado de trabalho e consequente sustentabilidade econômica dos países europeus.

O foco recai na Resolução 510/2016, que trata da pesquisa em Ciências Humanas e Sociais. Enquanto objetivos específicos da pesquisa estão o de extrair elementos de juridicidade que influenciam a formulação e a execução de pesquisas e enfocar aqueles de busca de proteção, promoção, efetivação e concretização de direitos humanos e fundamentais, o que se traduz em responsabilidade socioambiental do pesquisador responsável, sua equipe e da Universidade. O método da pesquisa é bibliográfico e documental, com reflexões sobre ética na pesquisa em geral e bioética em específico. Enquanto resultados, demonstra-se a relevância da referida normatividade em termos de composição dos objetos da pesquisa, eleição de métodos e estruturação dos projetos e sua execução, encaminhando as práticas rumo a pretensões de transformação social via horizontes jurídicos. Como considerações finais indica-se o potencial da adesão aos preceitos das Resoluções e seu fundo de referência em direitos humanos, exaltando-se que a pesquisa jurídica pode ser mais um dos vetores para consecução de direitos e políticas jurídicas.
Direito fundamental interdimensional ao afeto
Authors: Kowarski Clarissa Maria Beatriz Brandão de Carvalho , Alvarenga Samanta Francine
Published: May 2020

Os direitos fundamentais dotam-se de historicidade, tanto que são reconhecidos e inseridos em gerações/dimensões. Muito se fala no reconhecimento do afeto pelo Direito com o advento da Constituição Federal de 1988, embora o mesmo não tenha previsão expressa no texto constitucional. O afeto é inerente à pessoa humana e, portanto, um não pode ser pensado de modo desvinculado do outro, sendo imprescindível à proteção da dignidade humana e ao seu desenvolvimento psíquico. Nesse contexto, o presente artigo tem por objetivo analisar e compreender o afeto como um direito dotado de fundamentalidade e reconhecido em todas as dimensões de direitos fundamentais apontadas pela doutrina atualmente. Trata-se de uma pesquisa teórica e qualitativa, que utiliza como meios as revisões bibliográfica e documental.
Direitos da personalidade, vulnerabilidade e adolescente sob uma perspectiva winnicottiana
Authors: Siqueira Dirceu Pereira , Passafaro Valesca Luzia de Oliveira
Published: May 2020

O texto buscou compreender os aspectos emocionais e inconscientes que envolvem o ato de delinquir. Teve como referência principal a literatura Winnicottiana, que visa analisar o adolescente que vem a infringir condutas sociais, o ato da violência e quais as repercussões deste fenômeno na sociedade vigente. Buscou-se questionar  a questão da maioridade penal pontuando aspectos respeitáveis da visão psicanalítica que esclarecem o que é adolescer, e como estes processos podem ajudar a entender o que é a agressividade normal e patológica. Para este alcance, foi utilizado principalmente a questão postulada por Winnicott sobre sua obra Privação e Delinquência. Diante do grande fenômeno que a adolescência e a própria delinquência. As respostas que encontramos através da leitura Winnicottiana são de analise social, psíquica e jurídica; de que se consideramos o adolescente responsável pelos seus atos estaremos como sociedade podando toda possibilidade de recuperação emocional e social de alguém que esta pedindo socorro. Assim, no cerne da questão ficou evidente que é ainda através de prevenção e politicas publicas as melhores formas para modificar a grande questão da violência na adolescência.

Authors: Mauldin Thomas , Xu Zhenyu , Yao Zheyi , Wei Tao
Published: May 2020

This paper introduces an integrated optical time-domain reflectometry (iOTDR) design with low overhead based on several innovations, such as analog-to-probability conversion and probability density modulation, as well as well-known techniques. Due to the small form factor, low overhead, and CMOS compatibility of the proposed system, it holds the promise to be integrated with any optical communication transceiver. The prototyping system clearly demonstrates the feasibility of the proposed instrumentation by comparing its performance to a conventional OTDR setup that is based on an analog-to-digital converter. In addition, the system is integrated onto a custom printed circuit board to demonstrate the promise of future integration into optical transceivers. The experimental results demonstrate a spatial resolution of 23 cm, a sensitivity of

Published: May 2020

In pregnancy during an inflammatory condition, macrophages present at the feto-maternal junction release an increased amount of nitric oxide (NO) and pro-inflammatory cytokines such as TNF-α and INF-γ, which can disturb the trophoblast functions and pregnancy outcome. Measurement of the cellular and sub-cellular morphological modifications associated with inflammatory responses are important in order to quantify the extent of trophoblast dysfunction for clinical implication. With this motivation, we investigated morphological, cellular and sub-cellular changes in externally inflamed RAW264.7 (macrophage) and HTR-8/SVneo (trophoblast) using structured illumination microscopy (SIM) and quantitative phase microscopy (QPM). We monitored the production of NO, changes in cell membrane and mitochondrial structure of macrophages and trophoblasts when exposed to different concentrations of pro-inflammatory agents (LPS and TNF-α). In vitro NO production by LPS-induced macrophages increased 22-fold as compared to controls, whereas no significant NO production was seen after the TNF-α challenge. Under similar conditions as with macrophages, trophoblasts did not produce NO following either LPS or the TNF-α challenge. Super-resolution SIM imaging showed changes in the morphology of mitochondria and the plasma membrane in macrophages following the LPS challenge and in trophoblasts following the TNF-α challenge. Label-free QPM showed a decrease in the optical thickness of the LPS-challenged macrophages while TNF-α having no effect. The vice-versa is observed for the trophoblasts. We further exploited machine learning approaches on a QPM dataset to detect and to classify the inflammation with an accuracy of 99.9% for LPS-challenged macrophages and 98.3% for TNF-α-challenged trophoblasts. We believe that the multi-modal advanced microscopy methodologies coupled with machine learning approach could be a potential way for early detection of inflammation.
Pitch-rotational manipulation of single cells and particles using single-beam thermo-optical tweezers
Authors: Kumar Sumeet , Gunaseelan M. , Vaippully Rahul , Kumar Amrendra , Ajith Mithun , Vaidya Gaurav , Dutta Soumya , Roy Basudev
Published: May 2020

3D pitch rotation of microparticles and cells assumes importance in a wide variety of applications in biology, physics, chemistry and medicine. Applications such as cell imaging and injection benefit from pitch-rotational manipulation. Generation of such motion in single beam optical tweezers has remained elusive due to the complexities of generating high enough ellipticity perpendicular to the direction of propagation. Further, trapping a perfectly spherical object at two locations and subsequent pitch rotation hasn’t yet been demonstrated to be possible. Here, we use hexagonal-shaped upconverting particles and single cells trapped close to a gold-coated glass cover slip in a sample chamber to generate complete 360 degree and continuous pitch motion even with a single optical tweezer beam. The tweezers beam passing through the gold surface is partially absorbed and generates a hot-spot to produce circulatory convective flows in the vicinity which rotates the objects. The rotation rate can be controlled by the intensity of the laser light. Thus such a simple configuration can turn the particle in the pitch sense. The circulatory flows in this technique have a diameter of about 5 μm which is smaller than those reported using acousto-fluidic techniques.

Published: May 2020

We report on the development of 2D integrated multilayer Laue lens (MLL) nanofocusing optics used for high-resolution x-ray microscopy. A Micro-Electro-Mechanical-Systems (MEMS) - based template has been designed and fabricated to accommodate two linear MLL optics in pre-aligned configuration. The orthogonality requirement between two MLLs has been satisfied to a better than 6 millidegrees level, and the separation along the x-ray beam direction was controlled on a micrometer scale. Developed planar 2D MLL structure has demonstrated astigmatism free point focus of ∼14 nm by ∼13 nm in horizontal and vertical directions, respectively, at 13.6 keV photon energy. Approaching 10 nm resolution with integrated 2D MLL optic is a significant step forward in applications of multilayer Laue lenses for high-resolution hard x-ray microscopy and their adoption by the general x-ray microscopy community.
Tunable metamaterial filter for optical communication in the terahertz frequency range
Authors: Yang Wei , Lin Yu-Sheng
Published: May 2020

We present a design of a tunable terahertz (THz) filter (TTF) used in an indoor communication system. The unit cell of TTF is composed of ring-shaped and cross-shaped nanostructures. By utilizing the micro-electro-mechanical system (MEMS) technique to modify the height between the ring-shaped and cross-shaped nanostructures in the incident transverse electric (TE) mode, the resonant frequencies can be tuned from 0.530 THz to 0.760 THz, which covers an atmospheric window from 0.625 THz to 0.725 THz for indoor wireless optical communication applications. This design of TTF provides an effective approach to select and filter specific signals. It makes the data processing more flexible at the transmission end of the communication system. Furthermore, such a TTF design can be realized the commercialization of communication system components due to its integrated circuit (IC) process compatibility, miniaturization and high flexibility.
Multioptical bottles from second-order chirped symmetric Airy vortex beams
Authors: Xu Chuangjie , Wu You , Deng Dongmei
Published: May 2020

In this Letter, we introduce a new, to the best of our knowledge, structure of multioptical bottles formed by second-order chirped symmetric Airy vortex beams (CSAVBs). The numbers and the locations of the optical bottles embedded in the CSAVBs depend on the numbers and the locations of the vortices. Besides, the lengths and the sizes of the optical bottles could be adjusted by changing the chirp parameter and the topological charges of the vortices, respectively. We believe that our results can diversify the optical tweezers system for multiparticle manipulation.
Ruined intimacy and intimate ruins in Andrey Zvyagintsev’s Loveless (2017)
Authors: Andreescu Florentina C.
Published: May 2020

The collapse of the Soviet Union, followed by a period of cultural disorientation, and ensuing the rise of unfettered capitalism, offers scholars a conceptual magnifying glass with which to understand radical social change. Contemporary Russian popular culture, emerging in this unique social context, becomes a privileged venue to scrutinize the nature and implications of radical change. This article explores the transformations of intimacy through the lens of Andrey Zvyagintsev’s latest feature film Loveless (2017). This film captures a profound disruption of intimacy in compliance with market principles, technology and social media. Zvyagintsev juxtaposes instances of ruined intimacy with spaces of intimate physical ruins. The article suggests that the cinematic visual meditation on ruins and ruination implicates a more expansive meditation on the transient and permanent aspects of our lives, the intersection between nature and culture, as well as the play between presence and absence. By drawing on Aronson’s (2015) cross-cultural work on emotional frameworks, this article argues that Loveless (2017) shows how Aronson’s regime of (rational) choice colonizes the regime of (passionate) faith, with deleterious consequences.
Diversity and democratization of Dior in Australia: Social factors in fashion modification in the 1940s–50s
Authors: Hackett Lisa J.
Published: May 2020

Christian Dior’s 1947 ‘New Look’ collection has been widely examined for its influence on both haute couture and clothing styles in the 1950s. In the Australian context, Margaret Maynard examined how the New Look was marketed through the ideological positioning of women’s roles in the domestic sphere. This marketing campaign was spearheaded by two business syndicates who brought a series of French Fashion Parades to Australia in the late 1940s through the 1950s. Despite the hype around the parades, just how much the fashions were adopted by the wider public has not been measured. Australians did not adopt the New Look unchanged, instead local sensibilities, climate and culture meant modification was inevitable.

Through examining home-sewing patterns, photographs of key cultural events and images from popular magazines from the period, this article establishes how the New Look was modified in the Australia. Results show that despite the many women who were eager to embrace the new fashion, many more were reticent, clinging in particular to the shorter hemlines they had adopted during the war years. This led to a hybrid style that both followed the French lead and suited Australian society. French designers, keen to expand their business empires through licensing, responded to these adaptions, incorporating elements into their later collections. This represented a step away from the trickle-down model. This changing dynamic gave Australian customers the confidence to demand more from the fashion designers and to adapt fashion to suit the Australian context. By examining the impact of Dior’s New Look through the lens of ordinary Australian women, the influences of both the designer and his customers on the evolution of post-Second War World are exposed.
Punk aesthetics of Pedro Almodóvar’s Pepi, Luci, Bom: Self-reflexivity, subcultural formations and queer temporalities
Authors: Gürbüz Temmuz Süreyya
Published: May 2020

Tracing the direct and indirect influences and cultural connections between earlier counter-cultures and avant-garde art has been a useful method to historicize the aesthetics that is created by subcultures. Drawing from this approach, this article seeks to contribute to the study of the aesthetics and counter-cultures via analysing a specific cinematic self-reflexivity that is born out of the interconnectedness of low-budget material conditions and the subcultural environments. The contention is that Pedro Almodóvar’s first feature film Pepi, Luci, Bom y otras chicas del montón (1980), embodies such punk aesthetics and queer temporalities, through the temporary disruptions in narrative progression, the abundance of queer parody, the combination of camp, TV ads, musical performance and the non-diegetic insertions of comic book-style textuality. In this collage, the politics of realistic representation are thrown out of the picture via a deliberate coupling of artificiality and spontaneity. This article argues that the embeddedness of Pepi, Luci, Bom in Madrid’s subcultural movement, la movida madrileña, demonstrates perfectly how subcultural experience gives way to an aesthetic coping mechanism that transforms low-budget restrictions into self-reflexivity. The disparate narrative vantage points in the film that rupture linearity and how the subcultural environment prompted disruptive entrances through which the film’s satire emerged are taken as critical-aesthetic offerings of queer temporalities that exude through the experiential knowledge of exclusion and oppression.

Popular practices for online musicking and performance: Developing creative dispositions for music education and the internet
Authors: Cayari Christopher
Published: May 2020

Musicians’ drive to be productive on the internet led to the development of practices that can inform popular music education. Expanding the concept of popular music education to include online participatory culture practices provides inspiration for musicking online relevant not only in times of uncertainty (like during mandated quarantines experienced during the COVID outbreak in 2020), but also during times of prosperity when practices can be explored in classrooms and during leisure time. In this article, the author discusses three dispositions towards online musicking: DIY-disposition (do-it-yourself), DIWO-disposition (do-it-with-others) and DIFO-disposition (do-it-for-others). The development of these dispositions leads to online and musical literacies that help develop the skills needed for online musicking and performance. This text offers a creation theory about approaching online musicking that can be applied to new technologies and media as online platforms appear and fade on the internet.

Published: May 2020

Minden termelő vállalat életében nagyon fontos szerepet játszik a készlet és a raktár zavartalan működése, ezért elengedhetetlen a folyamatok folyamatos felülvizsgálata, új eljárások alkalmazása a hatékonyság növelése érdekében. A kutatás egyrészt a pallet shuttle állványrendszernek a kihasználtságával foglalkozik, másrészt fejlesztési lehetőséget is bemutat, amellyel a pallet shuttle rendszeren belül a raktározás és a komissiózás tevékenységét összevonjuk. Kutatásunk során megállapítottuk, hogy a vizsgált vállalatnak megéri két mozgó kocsit vásárolni, ezáltal a pallet shuttle állványrendszerek kihasználása 60%-ról 72%-ra, a raktár teljes kihasználtsága pedig 74%-ról 76%-ra növekedve. A pallet shuttle rendszeren belül a raktározás és komissiózás tevékenységének összevonása után megállapítottuk, hogy a targonca-vezető a raktározás után közvetlenül a komissiózás is elvégezhetné. A tevékenységek összevonása és az időtakarékosság lehetővé teszi, hogy műszakonként 4 helyett 3 targonca-vezető dolgozik.
Hőközpont felújításával kapcsolatos árajánlatok pénzügyi-gazdaságossági elemzése
Authors: Zsótér Brigitta
Published: May 2020

Egy hazai vállalat hőközpont felújítását vizsgálom. A vállalat igénybe vesz vidékfejlesztési támogatást is, ami a beruházás 50%-át fedezi. A különböző árajánlatokat 4 fő szempont alapján értékelem ez az NPV (nettó jelenérték), IRR (belső megtérülési ráta), DPB (dinamikus megtérülési idő), valamint Pl (jövedelmezőségi index) mutatókon keresztül.Két ajánlatot javaslok elfogadásra az 1. ajánlattevőtől, és egyet a másodiktól. A számítások elvégzése közben azt tapasztaltam, hogy a vidékfejlesztési támogatás igénybevétele nélkül szinte egyik árajánlat sem lett volna elfogadható.

A kultúra és a szakmai programok iránt érdeklődő lakosság és a turisták megelégedettségére a Szegedi Közlekedési Kft. időszakos trolibuszjáratokkal biztosította a rendezvényekre eljutást és a hazautazást. A hibrid trolibuszok csendes közlekedése elnyerte a lakosság elismerését - főleg - éjszakánként. A jövőben újabb vonalak felmérésére kerül sor, ahol járhatnak a korszerű Ikarus-Skoda önjáró trolibuszok.

Az Alkatrész Kft. készletezés hatékonyságának vizsgálata
Authors: Fazekas Andrea
Published: May 2020

Cikkemben egy hazai vállalat, az Alkatrész Kft. készletgazdálkodásának hatékonyságát vizsgálom. A vállalkozás két üzlethelyisége mellett több raktárt és letéti készletet is tart, így a cég vagyonának meghatározó része áll a készleteiben. A Kft. készletgazdálkodásának hatékonyságát a készletek forgási sebessége, az átlagos raktározási idő és a készlethatékonysági mutató kiszámításával elemzem. A vizsgálathoz szükséges adatokat és információkat egy strukturált interjú keretében kaptam meg a cég kereskedelmi vezetőjétől. A számítások elvégzése közben azt tapasztaltam, hogy a vállalkozás készletgazdálkodása nem túl hatékony. Ez nem feltétlenül jelenti a vállalat kudarcát, viszont célszerű lenne a termékek értékesítésének fellendítésre megfelelő marketing stratégiát alkalmazni, valamint mielőbb értékesíteni a nagy értékű speciális gyártású termékeket.

Az Y-generáció hamarabb, a Z-generáció később jelent meg a munkaerőpiacon. Mivel mindkét generáció szocializációjának nagy része a digitális világban történt, ezen két nemzedék - mint munkavállaló - számos tulajdonságában eltér a korábbi generációktól. Tanulmányunkban bemutatjuk, hogy az Y- és Z-generáció milyen vonásokat mutat a munkaerőpiacon.
Feketerothadás, az új kihívás a szőlő rezisztencia nemesítésében
Authors: Roznik Dóra , Hoffmann Sarolta , Kozma Pál
Published: May 2020

A feketerothadás a peronoszpóra és a lisztharmat mellett az egyik legveszélyesebb betegsége a világszerte termesztett szőlőnek, a Vitis vinifera-nsk. A megbetegedést a Guignardia bidwellii (Ellis) Viala & Ravaz) észak-amerikai eredetű gomba okozza. A kórokozó a 2000-es évek óta jelent súlyosabb problémát Európa számos borrégiójában a vegyszerhasználat mérséklését célzó törekvések miatt. Hazánkban 2010 óta rendszeresen megfigyelhető kártétele. A növényvédelemben a feketerothadás új kihívást jelent, mert a gomba fertőzésének kedvező meleg, csapadékos években akár a termésveszteség 100%-os is lehet. A Pécsi SZBKI szőlőnemesítési programjának célja a feketerothadás ellenállóság beépítése az innovatív lisztharmat és peronoszpóra rezisztens fajtajelöltekbe. Ezáltal megvalósíthatóvá válna a kiváló minőséget eredményező, permetezés nélküli szőlőtermesztés. Jelen tanulmány célja erről az új kórokozóról szerzett ismeretek, valamint a feketerothadás rezisztencia nemesítéséhez szükséges források kiválasztásának bemutatása. Eddigi vizsgálataink során újabb feketerothadás rezisztencia forrást emeltünk ki a nemesítési programunk számára, a 'Csillám' és a 'Seyval blanc' (Seyve-Villard 5276) fajtákat.
A talaj arzénterhelésének hatása a kísérleti növények arzéntartalmára nehézfémterheléses tartamkísérletben
Authors: Szegedi László , Nagy Péter Tamás
Published: May 2020

Az 1994 őszén az Eszterházy Károly Egyetem Tass-pusztai Tangazdaságában csernozjom barna erdőtalajon szabadföldi kisparcellás nehézfémterheléses tartamkísérlet indult 8 elem (Al, As, Cd, Cr, Cu, Hg, Pb, Zn) vízoldható sóival, 3 terhelési szinten (30, 90 és 270 kg elem/ha), 3 ismétlésben. Jelzönövényként 1998-ban borsó (Pisum sativum L.), 1999-ben silócirok (Sorghum bicolorL.), 2001-ben őszi árpa (Hordeum vulgare L.), 2002-ben fehérmustár (Sinapis alba L.), 2003- ban rostkender (Cannabis sativa L.) és 2005-ben lucerna (Medicago sativa L.) termesztésére került sor. A kísérlet során vizsgáltuk a talaj és a növények nehézfémtartalmát, amelynek ismeretében nyomon követhető a vizsgált elemek talajban való viselkedésének és talaj-növény rendszerben való mobilitásnak alakulása. Az arzén kifejezett depresszív hatása a kísérlet első két évében mutatkozott meg, a kísérlet további éveiben a vizsgált növények esetén mérséklődött, majd megszűnt. Az arzén a maximális terhelésnél sem dúsult a növényi szervekben, mindössze néhány növény vegetatív szerve mutatott némi akkumulációt. A kísérleti növények szemtermése védettnek bizonyult az arzénszennyezéssel szemben. A kísérleti eredmények alapján kijelenthető, hogy az arzén mozgása gátolt a talaj-növény rendszerben, mozgékonysága a kísérlet negyedik évétől jelentősen csökkent.
Predikciós statisztikai módszerek az ásványvízfogyasztás előrejelzésében

Published: May 2020

Magyarországon az ásványvízfogyasztás szokásai az elmúlt 40 évben gyökeresen megváltoztak. Az élelmiszerek közül ez a termékkategória produkálta a legnagyobb növekedést ezen időszak alatt, ugyanakkor az utóbbi években a növekedési ütem lelassult. Az ásványvíz kiskereskedelem monitorozását - fogyasztás mennyisége, kiszerelés típusa, kiszerelés mérete, márkák részesedése, átlagárak, bolt típusok részesedése - az AC Nielsen piackutató végzi, míg az ásványvízfogyasztás kedveltségét és gyakoriságát a GfK Piackutató Intézet „Étkezési Szokások" című kutatásaiban gyűjti. Kutatásunkban jellemezzük a hazai ásványvízfogyasztást, valamint statisztikai módszerekkel predikciót végzünk a fogyasztás várható alakulására. Kutatási kérdéseink a következők: 1. A predikciós modell becslése melyik évtől nem változik számottevően a további évek adatainak ismeretében, azaz mikortól működik rögzített paraméterekkel is megbízható előrejelzésként? 2. A modell alapján a fogyasztás hogyan alakul az elkövetkező években? Az eredményeink alapján 2010 óta a predikciós modell csupán a korábbi évek adataiból is jól becsüli a fogyasztást (RMSE 2011-2016<5 liter/fő/év). A modell a közeli évekre igen pontosan becsül (átlagos RMSEel5rcelsöév=3,01, átlagOS RMSEelöre második év=3,58, átlagos RMSEelöre harmadik év= 4,42 [liter/fŐ/év]). A modell alapján a következő 3 évben átlagosan 0,7 liter/fő/év lesz a növekedés, utána következő években a növekedés üteme lelassul, és a telítődést 127 liter/fő/év körüli fogyasztási szinttel éri el.
