Better Use Case Diagrams by Using Work System Snapshots
Authors: Bolloju Narasimha , Alter Steven
Published: May 2016

Research to date shows significant variability in the success of applying the common technique of use case diagramming for identifying information system scope in terms of use cases performed by actors interacting with an information system or performed automatically by the information system. The current research tests a) the benefits of using a work system snapshot, a basic analytical tool from the work system method, before producing use case diagrams, and b) the additional benefits of enhancing use case diagramming constructs to distinguish between automated activities, activities supported by the information system, and relevant manual activities. Teams of student subjects in an experiment produced substantially better use case diagrams - containing far more use cases and qualitatively better use cases than did the teams in control group - when provided with a work system snapshot that summarized a test scenario in terms of work system concepts.

Published: May 2016

This paper links research and teaching through an applied Soft Systems Methodology case study. The case study focuses on the redevelopment of a Research and Professional Skills module to provide support for international postgraduate students through the use of formative feedback with the aim of increasing academic research skills and confidence. The stages of the Soft Systems Methodology were used as a structure for the redevelopment of module content and assessment. It proved to be a valuable tool for identifying complex issues, a basis for discussion and debate from which an enhanced understanding was gained and a successful solution implemented together with a case study that could be utilised for teaching Soft Systems Methodology concepts. Changes to the module were very successful and resulted in significantly higher grades and a higher pass rate.

Published: May 2016

S. Alter's Work System Method is used in advancing the understanding and analyses of service innovation Business Process Outsourcing (BPO) from a business systems viewpoint. We propose to use this framework to distinguish what usually characterizes IT-enabled BPO service innovations, and which implications could be drawn for the underlying IS's design. We focus our analysis guided by the Traffic point banking BPO case study in Egypt. This paper brings forward important IS design considerations to the attention of systems analysts and designers to take into consideration while working on the conceptions of Innovative Service BPOs.
Assessing the Potential Improvement an Open Systems Development Perspective Could Offer to the Software Evolution Paradigm
Authors: Cowling James Austin , Ivins Wendy K.
Published: May 2016

Emerging stakeholder needs and a changing environment drive increasing demands for the constant adaption of software through maintenance and new capability development. A more evolutionary software engineering approach is sought to improve engineering responsiveness; Open System Development appears to offer a partial contribution but presents many challenges. This exploratory research proposes a new definition of the evolution of complex engineered systems, building on the essential features of ‘openness' described by Cowling et al (2014) and Lehman's (1980) ideas of evolutionary software. Using Checkland's (1999) Soft System Methodology enabled a structured literature review and analysis of the relative contributions of three divergent methodologies to the success of systems outcomes. These methodologies are: Plan-Driven, Agile, and Open Source Software Development. The analysis reveals several opportunities and highlights the critical issue of determining return on investment which needs to be overcome if an open approach is to contribute to evolutionary software engineering.

Authors: Salahshour Maryam , Dahlan Halina Mohamed , Iahad Noorminshah A.
Published: May 2016

Social networking tools have become an integral part of our daily lives. Recently, a new type of Social Networking Sites (SNSs) namely Academic Social Networking sites (ASNSs) has attracted global users. There is perceived usefulness on the impact of ASNSs on patterns of academic research activities. However, it remains unclear why some researchers do not use ASNSs at all. The purpose of this paper is therefore to explore the ASNSs usage among Malaysian academic researchers and to investigate benefits, specific purpose, drivers and barriers of using ASNSs. A total of 210 completed cases were collected through paper-based and online-based questionnaire. In order to show the outcome of the research, descriptive interpretation of data is performed. The overall findings of this research indicate that there is low rate of ASNSs usage among researchers. In addition, the results show that colleagues, attitude toward technology and communication benefits are the drivers to use ASNSs and trust, privacy and security are the common barriers regarding to use ASNSs.
Spatio-Temporal Denoising for Depth Map Sequences
Authors: Hach Thomas , Seybold Tamara
Published: May 2016

This paper proposes a novel strategy for depth video denoising in RGBD camera systems. Depth map sequences obtained by state-of-the-art Time-of-Flight sensors suffer from high temporal noise. Hence, all high-level RGB video renderings based on the accompanied depth maps' 3D geometry like augmented reality applications will have severe temporal flickering artifacts. The authors approached this limitation by decoupling depth map upscaling from the temporal denoising step. Thereby, denoising is processed on raw pixels including uncorrelated pixel-wise noise distributions. The authors' denoising methodology utilizes joint sparse 3D transform-domain collaborative filtering. Therein, they extract RGB texture information to yield a more stable and accurate highly sparse 3D depth block representation for the consecutive shrinkage operation. They show the effectiveness of our method on real RGBD camera data and on a publicly available synthetic data set. The evaluation reveals that the authors' method is superior to state-of-the-art methods. Their method delivers flicker-free depth video streams for future applications.

Published: May 2016

Emerging Internet of Things (IoT) technologies will allow spectators in a sport game to produce various video streams from various angles. With existing technologies, however, it is difficult to process massive and various data streams for multi-channel contents in real-time. To solve this problem, we aim to construct a software agent (called “Curator”) that compiles video contents automatically according to his/her values. In this paper, we propose a system to automatically switch multiple video streams that general sports spectators have taken using Random Forests classifier. Meta data such as image feature data and game progress data is extracted for each video scene as the input of the classifier. For evaluation, we constructed a camera switching timing estimation model using the live TV broadcast of some baseball game data. A video of another baseball game was curated with the constructed model. As a result, our system predicted the camera switching timing with accuracy (F-measure) of 85.3% on weighted average for the base camera work and 99.7% for the fixed camera work.

Today Sri Lankan broiler industry has changed, selling of the whole carcass to separated carcass parts or deboned parts. In the processing industry there is a higher demand to gain the higher edible part, muscle yield and specially the breast muscle. The study was conducted to investigate the effect of strain and housing condition (open and close houses) to determine the meat yield of the broiler carcass. Hubbard Classic (HC), Hubbard Flex (HF), Hubbard 15 (H15) and Cobb 500 (C500) were the four commercial strains. At 38 days of their age, a total of 160 birds (40 birds from each strain / 80 birds from each housing condition) were randomly selected, slaughtered, eviscerated, weights were measured and dissected in to the separated parts (breast, thigh and drumstick). Weights of the body parts were recorded, deboned and the meat yield was measured. The research was designs by two factorial design. Data were statistically analyzed by using two-way Analysis of Variances (ANOVA) of SAS, 9 version. The birds that reared under the close houses showed the highest drumstick meatiness (p<0.05). The ratio of the breast muscle weight to all other muscles, the meatiness of the thigh and breast were not significant affected from the housing condition. When considering the effect of the strain the HC has gained the overall superiority except the meatiness of the breast (p > 0.05) and the thigh (p < 0.05). The HF was resulted the highest ratio for it. Other four indicators the HC resulted the higher ratio over the other three strain (p<0.05). As a conclusion, it can be recommended to the industry, rearing of HC under closed house system to gain higher meat yield.

Osteoarthritis (OA) is a chronic disease of articular joints that leads to degeneration of both cartilage and subchondral bone. These degenerative changes are further aggravated by proinflammatory cytokines including IL-1β and TNF-α. Previously, we have reported that IL-3, a cytokine secreted by activated T cells, protects cartilage and bone damage in murine models of inflammatory and rheumatoid arthritis. However, how IL-3 protects cartilage degeneration is not yet known. In this study, we investigated the role of IL-3 on cartilage degeneration under both in vitro and in vivo conditions. We found that both mouse and human chondrocytes show strong expression of IL-3R at gene and protein levels. IL-3 increases the expression of mouse chondrocyte-specific genes, Sox9 and collagen type IIa, which were downregulated by IL-1β. Moreover, IL-3 downregulated IL-1β– and TNF-α–induced expression of matrix metalloproteinases in both mouse and human chondrocytes. Interestingly, IL-3 reduces the degeneration of articular cartilage and subchondral bone microarchitecture in a mouse model of human OA. Moreover, IL-3 showed the preventive and therapeutic effects on cartilage degeneration induced by IL-1β in micromass pellet cultures of human mesenchymal stem cells. Thus, to our knowledge, we provide the first evidence that IL-3 has therapeutic potential in amelioration of degeneration of articular cartilage and subchondral bone microarchitecture associated with OA.
Alveolar Epithelial Cell–Derived Prostaglandin E2 Serves as a Request Signal for Macrophage Secretion of Suppressor of Cytokine Signaling 3 during Innate Inflammation

Published: May 2016

Preservation of gas exchange mandates that the pulmonary alveolar surface restrain unnecessarily harmful inflammatory responses to the many challenges to which it is exposed. These responses reflect the cross-talk between alveolar epithelial cells (AECs) and resident alveolar macrophages (AMs). We recently determined that AMs can secrete suppressor of cytokine signaling (SOCS) proteins within microparticles. Uptake of these SOCS-containing vesicles by epithelial cells inhibits cytokine-induced STAT activation. However, the ability of epithelial cells to direct AM release of SOCS-containing vesicles in response to inflammatory insults has not been studied. In this study, we report that SOCS3 protein was elevated in bronchoalveolar lavage fluid of both virus- and bacteria-infected mice, as well as in an in vivo LPS model of acute inflammation. In vitro studies revealed that AEC-conditioned medium (AEC-CM) enhanced AM SOCS3 secretion above basal levels. Increased amounts of PGE2 were present in AEC-CM after LPS challenge, and both pharmacologic inhibition of PGE2 synthesis in AECs and neutralization of PGE2 in AEC-CM implicated this prostanoid as the major AEC-derived factor mediating enhanced AM SOCS3 secretion. Moreover, pharmacologic blockade of PGE2 synthesis or genetic deletion of a PGE2 synthase similarly attenuated the increase in bronchoalveolar lavage fluid SOCS3 noted in lungs of mice challenged with LPS in vivo. These results demonstrate a novel tunable form of cross-talk in which AECs use PGE2 as a signal to request SOCS3 from AMs to dampen their endogenous inflammatory responses during infection.
The Hayflick Limit May Determine the Effective Clonal Diversity of Naive T Cells
Authors: Ndifon Wilfred , Dushoff Jonathan
Published: May 2016

Having a large number of sufficiently abundant T cell clones is important for adequate protection against diseases. However, as shown in this paper and elsewhere, between young adulthood and >70 y of age the effective clonal diversity of naive CD4/CD8 T cells found in human blood declines by a factor of >10. (Effective clonal diversity accounts for both the number and the abundance of T cell clones.) The causes of this observation are incompletely understood. A previous study proposed that it might result from the emergence of certain rare, replication-enhancing mutations in T cells. In this paper, we propose an even simpler explanation: that it results from the loss of T cells that have attained replicative senescence (i.e., the Hayflick limit). Stochastic numerical simulations of naive T cell population dynamics, based on experimental parameters, show that the rate of homeostatic T cell proliferation increases after the age of ∼60 y because naive T cells collectively approach replicative senescence. This leads to a sharp decline of effective clonal diversity after ∼70 y, in agreement with empirical data. A mathematical analysis predicts that, without an increase in the naive T cell proliferation rate, this decline will occur >50 yr later than empirically observed. These results are consistent with a model in which exhaustion of the proliferative capacity of naive T cells causes a sharp decline of their effective clonal diversity and imply that therapeutic potentiation of thymopoiesis might either prevent or reverse this outcome.

Published: May 2016

The development of the fetal immune system during pregnancy is a well-orchestrated process with important consequences for fetal and neonatal health, but prenatal factors that affect immune activation are poorly understood. We hypothesized that chronic fetal inflammation may lead to alterations in development of the fetal immune system. To test this hypothesis, we examined neonates with gastroschisis, a congenital abdominal wall defect that leads to exposure of the fetal intestines to amniotic fluid, with resultant intestinal inflammation. We determined that patients with gastroschisis show high systemic levels of inflammatory cytokines and chemokines such as eotaxin, as well as earlier activation of CD4+ and CD8+ effector and memory T cells in the cord blood compared with controls. Additionally, increased numbers of T cells and eosinophils infiltrate the serosa and mucosa of the inflamed intestines. Using a mouse model of gastroschisis, we observed higher numbers of eosinophils and both type 2 and type 3 innate lymphoid cells (ILC2 and ILC3), specifically in the portion of organs exposed to the amniotic fluid. Given the role of IL-5 produced by ILC2 in regulating eosinophil development and survival, we determined that maternal or fetal administration of the anti–IL-5 neutralizing Ab, or a depleting Ab against ILCs, can both effectively reduce intestinal eosinophilia. Thus, a congenital anomaly causing chronic inflammation can alter the composition of circulating and tissue-resident fetal immune cells. Given the high rate of prenatal and neonatal complications in these patients, such changes have clinical significance and might become targets for fetal therapy.

The diversity, architecture, and dynamics of the TCR repertoire largely determine our ability to effectively withstand infections and malignancies with minimal mistargeting of immune responses. In this study, we have employed deep TCRβ repertoire sequencing with normalization based on unique molecular identifiers to explore the long-term dynamics of T cell immunity. We demonstrate remarkable stability of repertoire, where approximately half of all T cells in peripheral blood are represented by clones that persist and generally preserve their frequencies for 3 y. We further characterize the extremes of lifelong TCR repertoire evolution, analyzing samples ranging from umbilical cord blood to centenarian peripheral blood. We show that the fetal TCR repertoire, albeit structurally maintained within regulated borders due to the lower numbers of randomly added nucleotides, is not limited with respect to observed functional diversity. We reveal decreased efficiency of nonsense-mediated mRNA decay in umbilical cord blood, which may reflect specific regulatory mechanisms in development. Furthermore, we demonstrate that human TCR repertoires are functionally more similar at birth but diverge during life, and we track the lifelong behavior of CMV- and EBV-specific T cell clonotypes. Finally, we reveal gender differences in dynamics of TCR diversity constriction, which come to naught in the oldest age. Based on our data, we propose a more general explanation for the previous observations on the relationships between longevity and immunity.
ERβ in CD4+ T Cells Is Crucial for Ligand-Mediated Suppression of Central Nervous System Autoimmunity

Published: May 2016

The development of therapies for multiple sclerosis targeting pathogenic T cell responses remains imperative. Previous studies have shown that estrogen receptor (ER) β ligands could inhibit experimental autoimmune encephalomyelitis. However, the effects of ERβ-specific ligands on human or murine pathogenic immune cells, such as Th17, were not investigated. In this article, we show that the synthetic ERβ-specific ligand 4-(2-phenyl-5,7-bis[trifluoromethyl]pyrazolo[1,5-a]pyrimidin-3-yl)phenol (PHTPP) reversed established paralysis and CNS inflammation, characterized by a dramatic suppression of pathogenic Th responses as well as induction of IL-10–producing regulatory CD4+ T cell subsets in vivo. Moreover, administration of PHTPP in symptomatic mice induced regulatory CD4+ T cells that were suppressive in vivo. PHTPP-mediated experimental autoimmune encephalomyelitis amelioration was canceled in mice with ERβ-deficient CD4+ T cells only, indicating that expression of ERβ by these cells is crucial for the observed therapeutic effect. Importantly, synthetic ERβ-specific ligands acting directly on CD4+ T cells suppressed human and mouse Th17 cells, downregulating Th17 cell signature gene expression and expanding IL-10–producing T cells among them. TGF-β1 and aryl hydrocarbon receptor activation enhanced the ERβ ligand-mediated expansion of IL-10–producing T cells among Th17 cells. In addition, these ERβ-specific ligands promoted the induction and maintenance of Foxp3+ T regulatory cells, as well as their in vitro suppressive function. Thus, ERβ-specific ligands targeting pathogenic Th17 cells and inducing functional regulatory cells represent a promising subset of therapeutic agents for multiple sclerosis.
‘Publish or perish’: Family life and academic research productivity
Authors: Callaghan Chris W.
Published: May 2016

Research purpose: The influence of work-to-family and family-to-work spillovers is well documented in the human resources literature. However, little is known of the relationships between the pressures faced by academics to publish and the potential family life consequences of being a highly productive academic.Research design, approach and method: This research sought to investigate these relationships within the context of a large South African university by testing associations between family life variables such as marriage and dependent children against measures of the following specific types of research publication: (1) South African Department of Higher Education and Training–accredited journal publications; (2) Thompson Reuters Institute for Scientific Information (ISI) and ProQuest’s International Bibliography of the Social Sciences (IBSS)– indexed journal article publications; (3) conference proceedings publications; (4) conference paper presentations; (5) book chapter publications; (6) book publications; and (7) gross research productivity, reflecting a volume or quantity measure of research publication.Main findings: ISI and/or IBSS journal article publication is found to be negatively associated with dependent children, but only for male academics, and to be negatively associated with female gender over and above the effect of family life variables in testing.Practical/managerial implications: Human resources managers in universities need to be cognisant of the specific pressures faced by staff that are required to produce ever more research publications, in order to help them achieve work–life balance.Contribution: In a global context of increasing pressures for research publication, and for higher and higher numbers of publications, it is necessary to identify the potential costs involved for high-volume–producing academics, particularly in terms of family versus work.Keywords: research productivity; family-work life balance

Qué es Motion Graphics
Authors: Alonso Valdivieso Concepción
Published: May 2016

¿Qué son exactamente los Motion Graphics? Muchos aún no lo tienen claro. Si nos ceñimos a una simple traducción literal del término podríamos decir que son “grafismo en movimiento”, pero van mucho más allá. Los Motion Graphics son una técnica con gran capacidad de expresión, y por ello muy utilizada en publicidad, vídeos institucionales, secuencias de créditos, etc. Pueden traducir una compleja idea en un mensaje claro con unos pocos segundos de animación. Al mismo tiempo, los Motion Graphics poseen una estética muy particular, sencilla y muy elegante. Pero cualquier animación podría coincidir con estas características, entonces, ¿donde está la diferencia entre ellos y una animación de cualquier otro tipo? En este artículo trataremos de hallar la respuesta a través de un recorrido por su evolución y un análisis de sus componentes.
Redefiniendo una escuela de animación
Authors: García Moreno José
Published: May 2016

El departamento de Animación de la Universidad de Loyola Marymount (LMU) se fundó en los años noventa en base a la idea pedagógica del modelo de autor que Dan McLaughlin utilizó exitosamente en la Universidad de California, Los Ángeles (UCLA): un estudiante, un film. La naturaleza histórica y competitiva del mercado de la animación en Los Ángeles impulsó la búsqueda de una identidad propia, puesto que ello permitiría a la escuela distinguirse, competir y progresar. En 2007, el nuevo programa curricular impulsó el desarrollo del pensamiento crítico para la conceptualización de historias, la promoción y el respeto a la diversidad de las ideas en trabajos de grupo, un intenso programa clásico de dibujo, y procesos tecnológicos que favorecen un flujo eficiente de producción. El cambio elevó el valor de la producción, pero lo más importante es que promovió un inesperado cambio social y artístico que sigue afectando a la escuela en su conjunto. La redefinición de la escuela ha contribuido a educar varias generaciones de artistas tolerantes a la diversidad y entusiastas de la colaboración.

Individuals with Social Anxiety Disorder have difficulty disengaging from self-processing in social situations. Metacognitive therapy interventions for enhancing attentional control were administered to a convenience sample of 24 with a Social Anxiety Disorder diagnosis. Using a cross-over design, 11 participants were given four weekly sessions of Attention Training Technique (ATT), followed by four weekly sessions of Situational Attentional Refocusing (SAR). For the other 13 participants the two treatment components were given in the reverse order. All participants made significant reductions on interview rated and self-reported measures of social and general levels of anxiety by the end of the first intervention (either ATT or SAR). Following completion of the second treatment components, further reductions were observed and 46% (n = 11) of the total sample no longer met DSM-IV criteria for Social Anxiety Disorder diagnosis. Two large order effects were found favoring patients receiving SAR interventions first. Overall these brief techniques aimed at increasing attentional flexibility were associated with large and clinically significant changes in Social Anxiety Disorder symptoms.

The basis of differentiation between sun and shade leaves is related to different light intensities. In order to understand the adaptability of the leaves of Rhizophora mangle L., associated with different lighting conditions, leaves were collected from the upper peripheral six individuals (sun leaves) and the lower region of the same internal (shade leaves). The variables analyzed leaf thickness, palisade parenchyma, adaxial and abaxial epidermis, adaxial and abaxial cuticle, stomatal density and index. Measurements were made ??on microscope equipped with ocular micrometer. Sun leaves were lower and with more xeromorphic characteristics, such as increased thickness of the cuticle and the adaxial and abaxial epidermis. The palisade parenchyma and limbus showed up thicker than shade leaves, with no significant difference between the cuticle of the abaxial surface. It was also observed a higher frequency of stomata per mm², an average of 70/mm², while shade leaves showed 47/mm², with no differences between length and width. Differences between the sun leaves and shade leaves indicate adaptive capacity of this species to remain active at different light conditions.

Unlike carbon black, silica is polar and naturally not compatible with nonpolar hydrocarbon elastomers. This lack of interaction or compatibility between the filler and the elastomer typically causes lower properties compared with carbon black–filled compounds. A common approach to deal with this problem is to use silane coupling agents in the system to link the silica and the polymer chains via covalent bonds. An alternative is the introduction of polar functional groups or chemically reactive groups into the elastomer chains, which can improve the compatibility of elastomers with fillers such as silica. In this article, the effect of three functionalized SBRs, one backbone modified with carboxylate moieties, one modified with dithiol groups, and one partially Si-coupled, on the dynamic and mechanical properties of a silica-reinforced tire tread compound will be discussed and compared with a reference compound that contains unmodified s-SBR as the main polymer. The results show the significant potential of two of these modified SBRs to reduce the rolling resistance of tire treads made thereof, while no major change in wet grip occurs. Zinc oxide is known as the best activator for sulfur vulcanization. Zn ions combine with accelerators to form an active complex that catalyzes the vulcanization process. However, in silica-filled compounds, ZnO may interfere with the silanization process because of its alkaline nature, and it may compete with the silanes in reacting with the acidic –OH groups on the surface of silica particles. When functionalized SBRs with higher polarity are used in silica compounds, ZnO may interact with these moieties as well. To investigate the effect of ZnO on the properties of the silica-reinforced tread compound, a series of compounds have been prepared, in which the addition of ZnO in a later stage was compared with conventional mixing. The dynamic and mechanical properties of the final compounds are discussed.
Students’ Voice in Learning Style Assessment: The Innovative Learning Experiences Tool (ILE)
Authors: Mkonto Nosisana Patricia
Published: May 2016

Students who enter higher education have diverse learning needs, andhigher education institutions need to provide for these needs. One way of dealing with this variety of learning needs is to empower students to play an active role in their own learning, by making them aware of their learning styles.  Identifying learning styles is an important facet within the learning process. Assessing learning styles could provide students with an opportunity to be reflective, and interrogate how they learn. Students’ learning styles can be assessed by using a learning styles assessment tool. The Innovative Learning Experiences (ILE) which was developed in this study, caters for the students` voice where students reflect on their past and present learning experiences. 

 
POR UMA MILITÂNCIA ATIVA DA PALAVRA: ANTOLOGIAS, MOSTRAS, ENCONTROS E CRÍTICA SOBRE LITERATURA NEGRA, ANOS 1980
Authors: Silva Mário Augusto Medeiros da
Published: May 2016

O interesse do artigo é discutir eventos, obras e debates na conjuntura da década de 1980, em São Paulo, em que intelectuais negros e não negros, nacionais e estrangeiros, trataram da ideia de Literatura Negra e a história política e cultural negra no Brasil e no exterior. Desta maneira, abordam-se a produção de antologias e obras críticas sobre a Literatura Negra Brasileira (como Reflexões sobre a literatura afro-brasileira e Criação Crioula, Nu Elefante Branco) e os encontros promovidos por intelectuais negros ou pelo poder público paulistano e associações privadas (o I Perfil da Literatura Negra – Mostra Internacional de São Paulo e os debates sobre literatura negra na III Bienal Nestlé de Literatura).
JOÃO MULUNGU: A INVENÇÃO DE UM HERÓI AFRO-BRASILEIRO
Authors: Domingues Petrônio
Published: May 2016

O artigo tem a finalidade de investigar o processo de construção de um herói afro-brasileiro. Sua questão central é saber como João Mulungu – considerado o mais notável líder quilombola de Sergipe na segunda metade do século XIX – foi revalorizado nos domínios da memória por parte de setores do movimento negro nas décadas de 1980 e 1990 e promovido à condição de primeiro herói negro do estado reconhecido oficialmente. Esta representação de João Mulungu não deve ser vista tão somente como uma falsa verdade, mas sim ressignificação da memória, fenômeno social que faz parte do processo histórico.
Folklore’s Cybernetic Imaginary, or, Unpacking the Obvious
Authors: Dorst John D.
Published: May 2016

This essay attempts to unpack a core principle of folklore’s "field-Imaginary." Characterized here as a cybernetic Ideal, folklorists take for granted that the folklore process entails a tension between mechanisms of randomizing variation and counter forces of stabilizing constraint, leading to some form of dynamic equilibrium. The argument is not that this foundational idea is wrong, but that the simple form in which we receive it from the field-Imaginary limits what we recognize as relevant to folklore studies. A more complex understanding of (neo)cybernetic thinking can help us enlarge our disciplinary frame and contemplate more critically the digital/ computational turn in folklore studies today.
Da necessidade de um tipo penal intermediário no crime de estupro em face da desproporcionalidade da pena
Authors: Tanferri Andressa Silveira , Cachapuz Rozane Da Rosa
Published: May 2016

O artigo versa de forma crítica sobre a desproporcionalidade da pena mínima cominada ao crime de estupro, previsto no art. 213 do Código Penal Brasileiro, quando aplicado a condutas que causam menor lesão ao bem jurídico da vítima. A temática abrange a necessidade da criação de um tipo penal intermediário que supra a lacuna legal existente e seja viável para punir as condutas menos gravosas, sem que isso viole os princípios fundamentais inerentes tanto ao autor quanto à vítima do crime. Expõem-se, para tanto, os contornos conceituais, a análise do bem jurídico protegido e da figura típica abarcada pelo delito, os princípios aplicáveis à espécie, os motivos que tornam insuficiente a norma penal existente, bem como a aplicação prática das alternativas jurisprudenciais criadas para diminuir a desproporção.
Reflexões sobre flexibilização de horas in itinere e desenvolvimento sustentável
Authors: Hupffer Haide Maria , Pereira João Luis Kleinowski , Naime Roberto Harb
Published: May 2016

A concentração de indústrias em centros urbanos atrai a necessidade de maior infraestrutura de transporte e, dada a deficiência do transporte público, particulares optam por utilizar seus veículos individuais. Alternativa poderia ser a instalação de parques fabris em localidades remotas, entretanto, diversas são as dificuldades econômicas para viabilizá-la. As horas in itinere, por exemplo, decorrem da CLT – Consolidação das Leis do Trabalho – e constituem obrigação de pagamento ao empregado pelo tempo despendido no deslocamento até a empresa instalada em local de difícil acesso ou não servida por transporte público e vice-versa, sempre que o transporte for fornecido pelo empregador. Referida obrigação, em certa medida, tem dado causa à superlotação de grandes centros. A conjugação de acontecimentos sinaliza que os malefícios trazidos pela medida são sobremaneira maiores do que os benefícios, permitindo-se concluir pela necessidade de reavaliação da obrigação imposta pela norma trabalhista que incentiva o desenvolvimento de regiões urbanas em detrimento das demais regiões do país.
Os direitos sociais como elemento de sustentabilidade e fundamentação do Estado Democrático de Direito
Authors: Gervasoni Tássia Aparecida , Bolesina Iuri
Published: May 2016

Os direitos sociais expressam o desejo de realização de uma igualdade que seja substancial. Contudo, verifica-se ainda grande resistência não só ao reconhecimento do status de direito fundamental a esses direitos como também à vinculação imediata e direta do Estado na sua prestação. A partir disso, o presente trabalho pretende desconstruir algumas dessas críticas no sentido de demonstrar a fundamentalidade dos direitos sociais, bem como sua inegável importância ético-jurídica na estruturação e sustentação do próprio Estado Democrático de Direito.
Haveria base nomrativa para restringir as receitas da previdência social às contribuições previdenciárias?
Authors: Aguiar Mauro Da Motta
Published: May 2016

Manifestações a respeito da “difícil” situação da Previdência Social adotam como tese subjacente que o custeio do RGPS dever-se-ia restringir às receitas oriundas das contribuições sobre a folha de salários. Daí surgiu, então, o questionamento de até que ponto seria efetivamente viável identificar-se, no direito positivo brasileiro vigente, quais, dentre as receitas previstas para o financiamento da Seguridade Social, poderiam ser entendidas como destináveis à Previdência Social, inquirição essa que constituiu o objetivo deste trabalho. O exame da matéria iniciou-se pelo texto da Lei Maior. As acusações que se fazem quanto ao teor generoso da Constituição Cidadã conduziram a que também se pesquisasse a situação nos normativos legais expedidos no período precedente. Após tal busca regressiva, analisou-se o tratamento da matéria no principal instrumento infraconstitucional a ela dedicado, a saber, a Lei 8.212/1991. O estudo findou por demonstrar a inviabilidade de identificar-se suporte, a partir da leitura direta do texto constitucional ou daquele das leis que dispõem sobre o tema, para a tese que pretende restringir, entre as receitas da Seguridade Social, o leque daquelas que podem ser utilizadas pela Previdência Social.
Responsabilidade civil ambiental no direito constitucional brasileiro: uma análise da evolução histórica
Authors: Braga e Silva Larissa Gabrielle , Rezende Élcio Nacur
Published: May 2016

O presente artigo tem por escopo empreender um estudo acerca do tratamento constitucional brasileiro conferido ao instituto da responsabilidade civil ambiental. Tal instituto adentra no ordenamento jurídico constitucional de forma especial e única na Constituição da República Federativa do Brasil de 1988, estampado em seu artigo 225, parágrafo terceiro. A Constituição Federal confere ampla tutela ao meio ambiente e o insere no rol dos direitos sociais e ainda lhe atribui status de direito fundamental. No tocante à responsabilidade civil ambiental, a Constituição recepciona o conteúdo normativo do artigo 14, parágrafo primeiro, da Lei que institui a Política Nacional do Meio Ambiente, Lei 6.938/81, e contempla a responsabilização objetiva ambiental. O estudo do chamado Estado de Direito Socioambiental constitui o novo e necessário paradigma de Direito que apresenta proposta conjuntiva dos direitos econômicos, sociais, culturais e ambientais e advoga a ideia de um mínimo existencial amplo, não meramente físico ou biológico. Por fim, a responsabilidade civil foi enaltecida em sua aplicação objetiva em seus alcances individual e coletivo. A pesquisa bibliográfica foi a metodologia utilizada, cujo método dedutivo corroborou para as conclusões realizadas através deste estudo. Conclui-se que a responsabilidade civil ambiental é instituto que se associa à consolidação de um Estado Socioambiental de Direito e que este é um desafio que a todos, indistintamente, se apresenta.
