Rap2B promotes angiogenesis via PI3K/AKT/VEGF signaling pathway in human renal cell carcinoma
Authors: Di Jiehui , Gao Keyu , Qu Debao , Wu Yaoyao , Yang Jing , Zheng Junnian
Published: August 2017

Human renal cell carcinoma which is a highly vascular tumor is the leading cause of death from urologic cancers. Angiogenesis has a pivotal role in oncogenesis and in the viability and expansion of renal cell carcinoma. Rap2B, as a small guanosine triphosphate–binding protein of the Ras family, was first discovered in the early 1990s during the screening of a platelet complementary DNA library. Previous studies have shown that Rap2B aberrantly expressed in human carcinogenesis and promoted the development of tumors via multiple signaling pathways. However, the function of Rap2B in tumor angiogenesis that is necessary for tumor growth and metastasis remains unknown. In this study, we examined the role of Rap2B in angiogenesis in renal cell carcinoma by Western blot, quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, human umbilical vascular endothelial cells growth assay, and endothelial cell tube formation assay. We found that Rap2B promoted angiogenesis in vitro and in vivo. Moreover, our data illustrated that phosphoinositide 3-kinase/AKT signaling pathway is involved in Rap2B-mediated upregulation of vascular endothelial growth factor and renal cell carcinoma angiogenesis. Taken together, these results revealed that Rap2B promotes renal cell carcinoma angiogenesis via phosphoinositide 3-kinase/AKT/vascular endothelial growth factor signaling pathway, which suggests that Rap2B is a novel therapeutic target for renal cell carcinoma anti-angiogenesis therapy.
Living in the Age of Austerity and Migration
Authors: Xu Qingwen , Halsall Jamie P.
Published: August 2017

The global financial crisis of 2008 has caused much dialogue within the social policy framework on how to maintain a sustainable elderly health-care system. This coupled with a migrant crisis have created extra social and economic pressures in Europe in particularly. As it has been well documented by social scientists, people are living longer than ever before. There are two fundamental factors that are helping people live to an old age, which are as follows: (a) a better quality of life and (b) improved health-care system at state level. However, since the global financial crisis of 2008 populations across the world are living in an age of austerity. The age of austerity has brought extra financial pressures on the state, polarizing society by implementing cuts in welfare. The reason many governments across the world (e.g., United States, United Kingdom, and Greece) have enforced a series of austerity measures is fundamentally to reduce debt. The aim of this article is to critically explore the austerity social policy agenda within the context of the debates surrounding the refugee or migrant crisis in the elderly health-care system.
Caregiver Report of Child Symptoms Predicts Attrition in Abuse-Specific Cognitive Behavioral Therapies
Authors: Tebbett Alison A. , Brown Elissa J. , Chaplin William F.
Published: August 2017

A common critique of empirically supported treatments for abuse-related psychopathology is attrition during critical phases of therapy (i.e., exposure). The goal of this study was to examine whether child and caregiver symptoms were predictive of attrition among families in abuse-specific cognitive–behavioral therapies (CBTs). Children ( N = 104) and their caregivers completed baseline assessments of internalizing symptoms, externalizing problems, and post-traumatic stress disorder (PTSD) and were enrolled in abuse-specific CBTs. Logistic regressions were conducted with baseline symptoms as predictor variables and treatment status (attrition vs. completion) as the criterion variable. Caregiver report of child internalizing symptoms showed the predicted quadratic relation to attrition. Caregiver report of child externalizing symptoms at moderate and high (vs. low) levels was associated with attrition. Child self-report and caregiver self-report of symptoms were not associated with the dyad’s attrition. These results underscore the importance of attending to caregivers’ initial perceptions of children’s symptoms in abuse-specific therapy.
Association of ADHD and Executive Functioning With Childhood Depression
Authors: Fenesy Michelle C. , Lee Steve S.
Published: August 2017

Objective: Despite its association with increased severity and treatment resistance, relatively little is known about the correlates of early-onset childhood depression. ADHD and executive functioning (EF) are each related to depression. Given their covariation, we tested the independent association of ADHD dimensions (i.e., inattention, hyperactivity) and EF with childhood depression using structural equation modeling to identify potential targets for intervention. Method: Participants were 225 five- to 10-year-old children (68% male) with ( n = 117) and without ( n = 108) ADHD. Youth completed laboratory assessments of EF, and parent, teacher, and youth reports of depression were gathered. Results: With control of EF and anxiety, across informants, inattention, but not hyperactivity, was positively related to child depression. EF was positively associated with depression according to parent ratings only. Conclusion: We consider the association of inattention and EF with childhood depression, including implications for intervention and prevention from a developmental psychopathology framework.
Fighting for attention: Media coverage of negative campaign messages
Authors: Haselmayer Martin , Meyer Thomas M , Wagner Markus
Published: August 2017

The article studies whether and how negative campaigning is a successful strategy for attaining media attention. It combines extensive content analyses of party and news texts with public opinion surveys to study the success of individual press releases in making the news. The empirical analysis draws on 1496 party press releases and 6512 news reports in all national media outlets during the final 6 weeks of Austria’s 2013 general election campaign. We find that negative campaigning is a successful strategy to attract the attention of journalists and editors. It is particularly relevant for rank-and-file politicians, who lack the intrinsic news value of high public or party office, and for messages that focus on a rival’s best issues. These findings have broader implications for understanding party strategies and ‘negativity bias’ in the news.
Sublime selfies: To witness death
Authors: Du Preez Amanda
Published: August 2017

Selfies have become more dangerous than sharks, if the 15 reported selfie deaths in 2015 are compared to the eight shark attacks in the same year. Determining the exact parameters for a selfie death or death by selfie is difficult; in some cases, one may argue that the selfie is not the cause of death but in fact only occurs tragically before the event. The focus of this article falls on those selfies that were taken in pursuit of experiencing a sublime encounter with mortality and that in the end succeeded in evoking that looming encounter. It is argued that the obsession to experience the inexplicable is, however, not a recent endeavour, and the sublime is a useful aesthetic category to unpack the phenomenon of selfie deaths. In the analysis, three categories are identified to interpret the subject, namely, selfies unknowingly taken before death, selfies of death where the taker’s death is almost witnessed and selfies with death where the taker stands by while someone else dies. The emphasis falls on the analysis of selfies of death that overlaps with the sublime experience almost entirely, and it becomes nearly impossible to distinguish between selfie and sublimity.
Gender justice discourse in the educational system of Afghanistan during the Marxist period (1978–1992)
Authors: Sokhanwar M Davood , Sajjadi Seyed Mahdi , Baiza Yahia , Imani Mohsen
Published: August 2017

This study examines women’s access to education (‘gender justice’) during the rule of the People’s Democratic Party of Afghanistan from 1978 to 1992, using a qualitative research methodology and discourse analysis at the operational level from the perspective of Laclau and Mouffe’s discourse theory. The data collected in this research were extracted from textual sources concerning the role of women in education in Afghanistan in the Marxist era: the importance of the data concerns an understanding of the intellectual and political atmosphere, particularly with regard to women’s education, in the government of the time. It is concluded that several factors contributed to the failure of the hegemonic discourse, despite intensive efforts made by Marxist government to realize hegemony and gender justice. Political agents, availability, credibility and exclusion, as elements of the hegemonic discourse, were evaluated and it is further concluded that these elements were unable to play an effective role in the discourse, as had been expected, and were gradually marginalized.
“Images from beyond the Eastern Border”: Socialist Television in Finland, 1963 to 1988
Authors: Pajala Mari
Published: August 2017

Recent research has criticized a tradition of seeing socialist media cultures as strictly separated from the West. While scholars have analyzed how socialist television institutions reacted to influences from Western media, there is little research on how socialist television culture traveled outside the socialist bloc. This article analyses the ways in which state socialist television culture appeared in Finland on the basis of the main Finnish TV guide magazine Katso in 1963, 1968, 1973, 1978, 1983, and 1988. The article argues that socialist television was a significant influence in the Finnish television environment. Finnish audiences were introduced to socialist television cultures through means such as cross-border access to Soviet broadcasts and journalistic depictions. Both public service and commercial television companies imported Eastern European programs of various genres. Thus, the Finnish case shows that a strict East/West binary is not helpful for understanding European television history.
The Impact of Face Inversion on Animacy Categorization
Authors: Balas Benjamin , van Lamsweerde Amanda E. , Auen Amanda , Saville Alyson
Published: August 2017

Face animacy perception is categorical: Gradual changes in the real/artificial appearance of a face lead to nonlinear behavioral responses. Neural markers of face processing are also sensitive to face animacy, further suggesting that these are meaningful perceptual categories. Artificial faces also appear to be an “out-group” relative to real faces such that behavioral markers of expert-level processing are less evident with artificial faces than real ones. In the current study, we examined how categorical processing of real versus doll faces was impacted by the face inversion effect, which is one of the most robust markers of expert face processing. We examined how explicit categorization of faces drawn from a real/doll morph continuum was affected by face inversion (Experiment 1) and also how the response properties of the N170 were impacted by face animacy and inversion. We found that inversion does not change the position or steepness of the category boundary measured behaviorally. Further, neural markers of face processing are equally impacted by inversion regardless of whether they are elicited by real faces or doll faces. On balance, our results indicate that inversion has a limited impact on the categorical perception of face animacy.
Decentering Attenuates the Associations of Negative Affect and Positive Affect With Psychopathology
Authors: Naragon-Gainey Kristin , DeMarree Kenneth G.
Published: August 2017

Theory on decentering—an observer perspective on one’s ongoing internal experiences—suggests that decentering may be a protective factor against extreme affective states in predicting psychopathology. The current studies were the first to empirically test this, using multiple measures of decentering to capture two distinct components. Across three student samples and two clinical samples, we investigated whether trait decentering moderated the relationship of negative affect and positive affect with a variety of internalizing symptoms, as well as with narcissism, mania, and anhedonia. Greater decentering attenuated the associations of negative affect with dysphoria and panic symptoms, in both cross-sectional (Study 1) and ecological momentary assessment (Study 2) designs. Exploratory analyses in a single sample revealed that positive affect interacted with decentering to predict anhedonia and narcissism symptoms. Implications are discussed for understanding the effects of decentering on psychopathology and refining interventions, as well as the conceptualization and assessment of decentering.

Published: August 2017

Research on the association between chronic bronchitis and chronic obstructive pulmonary disease (COPD) exacerbations has led to discordant results. Furthermore, the impact of chronic bronchitis on mortality in COPD subjects is unclear.

Within the Rotterdam Study, a population-based cohort study of subjects aged ≥45 years, chronic bronchitis was defined as having a productive cough for ≥3 months per year for two consecutive years. Linear, logistic regression and Cox proportional hazard models were adjusted for age, sex and pack-years.

Out of 972 included COPD subjects, 752 had no chronic phlegm production (CB−) and 220 had chronic phlegm production, of whom 172 met the definition of chronic bronchitis (CB+). CB+subjects were older, more frequently current smokers and had more pack-years than CB−subjects. During a median 6.5 years of follow-up, CB+subjects had greater decline in lung function (−38 mL·year−1, 95% CI −61.7–−14.6; p=0.024). CB+subjects had an increased risk of frequent exacerbations (OR 4.0, 95% CI 2.7–5.9; p<0.001). In females, survival was significantly worse in CB+subjects compared to CB−subjects. Regarding cause-specific mortality, CB+subjects had an increased risk of respiratory mortality (hazard ratio 2.16, 95% CI 1.12–4.17; p=0.002).

COPD subjects with chronic bronchitis have an increased risk of exacerbations and respiratory mortality compared to COPD subjects without chronic phlegm production.
Do Biology Majors Really Differ from Non–STEM Majors?
Authors: Cotner Sehoya , Thompson Seth , Wright Robin
Published: August 2017

Recent calls to action urge sweeping reform in science education, advocating for improved learning for all students—including those majoring in fields beyond the sciences. However, little work has been done to characterize the differences—if any exist—between students planning a career in science and those studying other disciplines. We describe an attempt to clarify, in broad terms, how non–STEM (science, technology, engineering, and mathematics) majors differ from life sciences majors, and how they are similar. Using survey responses and institutional data, we find that non–STEM majors are not unilaterally science averse; non–STEM majors are more likely than biology majors to hold misconceptions about the nature of science, yet they are not completely ignorant of how science works; non–STEM majors are less likely than biology majors to see science as personally relevant; and non–STEM majors populations are likely to be more diverse—with respect to incoming knowledge, perceptions, backgrounds, and skills—than a biology majors population. We encourage science educators to consider these characteristics when designing curricula for future scientists or simply for a well-informed citizenry.
The Swahili Art of Indian Taarab
Authors: Eisenberg Andrew J.
Published: August 2017

Employing approaches from ethnomusicology and vocal anthropology, Eisenberg undertakes an interpretive-ethnographic analysis of Indian taarab, a genre of Swahili song on the Kenyan coast that features Swahili words set to Hindi film song melodies performed in a distinctly Indian style. Eisenberg argues that Swahili musicians and audiences derive pleasure and meaning from Indian taarab's paradoxical presentation of Indian sounds as Swahili expressions, and that this positions the genre as a vehicle for public reflection on Swahili ethnicity. Focusing on the voice and vocality, he explores how certain Indian taarab singers—the genre's “clowns”—engage in a reflexive critical analysis of Swahili ethnicity by playfully making audible the Indianness that resonates within the space of Swahili ethnicity (uswahili). Ultimately, the essay seeks to generate new perspectives on social identification among Kenyan coastal Muslims by taking an ethnographic ear to Indian taarab clowning and its “harlequin poetics.”
A role for tight junction-associated MARVEL proteins in larval sea lamprey (Petromyzon marinus) osmoregulation
Authors: Kolosov Dennis , Bui Phuong , Donini Andrew , Wilkie Mike P. , Kelly Scott P.
Published: August 2017

This study reports on tight junction-associated MARVEL proteins of larval sea lamprey (Petromyzon marinus) and their potential role in ammocoete osmoregulation. Two Occludin isoforms (designated Ocln and Ocln-a) and a tricellulin (Tric) were identified. Transcripts encoding ocln, ocln-a, and tric were broadly expressed in larval lamprey, with greatest abundance of ocln in gut, liver and kidney, ocln-a in the gill and skin, and tric in the kidney. Ocln and Ocln-a resolved as ∼63 kDa and ∼35 kDa MW proteins respectively while Tric resolved as a ∼50 kDa protein. Ocln immunolocalized to the gill vasculature and in gill mucous cells while Ocln-a localized to the gill pouch and gill epithelium. Both Ocln and Ocln-a localized in the nephron, the epidermis and the luminal side of the gut. In branchial tissue, Tric exhibited punctate localization, consistent with its presence at regions of tricellular contact. Following ion-poor water (IPW) acclimation of ammocoetes, serum [Na+] and [Cl−] reduced, but not [Ca++], and carcass moisture content increased. In association, Ocln abundance increased in skin and kidney, but reduced in gill of IPW-acclimated ammocoetes while Ocln-a abundance reduced in the kidney only. Tric abundance increased in the gill. Region-specific alterations in ocln, ocln-a and tric mRNA abundance was also observed in the gut. Data support a role for Ocln, Ocln-a and Tric in the osmoregulatory strategies of a basal vertebrate.
Pathogenic helminths in the past: Much ado about nothing
Authors: Mulder Christian
Published: August 2017

Despite a long tradition on the extent to which Romanisation has improved human health, some recent studies suggest that Romanisation in general, and Roman sanitation in particular, may not have made people any healthier, given that in Roman times gastrointestinal parasites were apparently widespread, whilst in the present day such parasites rarely cause diseases. Unfortunately, this novel claim neglects the empirical evidence that worldwide infections in over 1.5 billion people are caused by ubiquitous foodborne nematodes. Therefore, many may wonder if fossil remains of soil-transmitted helminths have been reported in ancient sanitation infrastructures. Beneficial access to improved sanitation should always be prioritized, hence how can historical sanitation efforts have ever been harmful? In this short article, a strong plea for caution is given, asking for an augmented nematological record and showing that there is not any evidence against Roman sanitation, neither in the past nor in the present.

Published: August 2017

Based on the factor of parametric modeling specifically given system “object — factors — protection worker” the problem of determining a quantitative measure of the possible implementation options (outcomes) of the occurrence of the incident was testedby: 1) construction of parametric and logical assumptions; 2) identifying their coherence in relation to the selected occurrence, and 3) calculating possible (fuzzy) measures of the occurrence of the incident taking into account the completeness and reliability of the initial data about the system. The numerical estimation of safety parameters in practically important region of analysis is given: the impact of “less” or “much less” susceptibility. The demonstration of the possible use of parametric models “impact — attenuation — sensitivity” in the range of occurrence of apical outcomes from injury (disease) to a critical, or death is given. It is shown that the proposed method of security analysis and the calculation algorithm is standardized and can be applied to assess both integral and differential risk of complex systems.

The article gives the results of retrospective statistical analysis, which justify the presence of statistical dependencies between the dates of the beginning and the peak values of the spring phytoplankton bloom in the Uchinsk reservoir and the intensity of total solar radiation in the range of photosynthetically active radiation (PAR), as well as the value of the integral indices of the activity of the Sun (Wolf number), in the period preceding of phytoplankton bloom. It is found, that the greater the magnitude of the fluxes of solar radiation in the PAR range will get the surface of the reservoir for 28 days of February this year, the later will be observed peaks of the spring phytoplankton bloom.A positive correlation between the parameters of the light regime (the sum of PAR) and the period of the onset of the algae “bloom” in the reservoir is apparently related to the photoinhibition of phytoplankton development directly under the ice, which leads to a later development of the spring “bloom”.The verification of the obtained regression equation showed a good correspondence of actual and calculated dates of spring “bloom” for a ten-year period. A negative correlation was found between the values of Wolf numbers (in February and the average annual values of the current year) and the dates of the spring peaks of phytoplankton bloom, which can be explained by the stimulating nature of the effect of the intensity of natural magnetic fields on the development of phytoplankton.The results of the investigations are of undoubted interest for the analysis of the influence of the light factor and the integral activity of the Sun on the seasonal dynamics of phytoplankton in the reservoir, as well as for an accurate forecast of the onset of spring phytoplankton bloom in drinking-water reservoirs in planning water treatment and water treatment activities.
Simple Contracts to Assure Supply Under Noncontractible Capacity and Asymmetric Cost Information
Authors: Bolandifar Ehsan , Feng Tianjun , Zhang Fuqiang
Published: August 2017

This paper studies a global sourcing problem where a buyer sources a product from a supplier to satisfy uncertain market demand. With the increasing length and complexity of today’s global supply chains, the buyer may face two issues when designing the sourcing contract: adverse selection (i.e., the supplier’s cost structure is private information) and noncontractible capacity (i.e., the supplier’s capacity investment is not contractible). We show that noncontractible capacity does not necessarily lead to a lower profit for the buyer, but it may require a more complex contract format to achieve the optimal (second-best) profit. Interestingly, we find that a single, linear contract (or a two-part tariff) could be optimal for the buyer under certain conditions. Even when such a contract is suboptimal, it can deliver close-to-optimal profit for the buyer for a wide range of situations. These findings indicate that the value of using a complex menu of contracts is negligible in such a supply chain setting. A simple two-part tariff is an attractive option for buyers whose goal is to ensure supply while facing both cost uncertainty and contractibility issues. The paper also provides a new explanation for the prevalence of such simple contracts in practice.

Shelter Location and Evacuation Route Assignment Under Uncertainty: A Benders Decomposition Approach
Authors: Bayram Vedat , Yaman Hande
Published: August 2017

Shelters are safe facilities that protect a population from possible damaging effects of a disaster. For that reason, shelter location and traffic assignment decisions should be considered simultaneously for an efficient evacuation plan. In addition, as it is very difficult to anticipate the exact place, time, and scale of a disaster, one needs to take into account the uncertainty in evacuation demand, the disruption/degradation of evacuation road network structure, and the disruption in shelters. In this study, we propose an exact algorithm based on Benders decomposition to solve a scenario-based two-stage stochastic evacuation planning model that optimally locates shelters and that assigns evacuees to shelters and routes in an efficient and fair way to minimize the expected total evacuation time. The second stage of the model is a second-order cone programming problem, and we use duality results for second-order cone programming in a Benders decomposition setting. We solve practical-size problems with up to 1,000 scenarios in moderate CPU times. We investigate methods such as employing a multicut strategy, deriving Pareto-optimal cuts, and using a preemptive priority multiobjective program to enhance the proposed algorithm. We also use a cutting plane algorithm to solve the dual subproblem since it contains a constraint for each possible path. Computational results confirm the efficiency of our algorithms.

O instrumento obteve índices confiáveis. Realizou-se análise estatística e os resultados demonstraram que a universidade empreendedora deve ser mais atuante. Discentes que cursaram disciplinas relacionadas ao empreendedorismo e aqueles que trabalham obtiveram pontuação superior em detrimento aos demais. Os resultados do presente estudo podem contribuir para novas pesquisas relacionadas à temática. O estudo limitou-se à amostra pesquisada. Sugere-se que estudos futuros contemplem uma amostra maior em diferentes instituições e que também considerem professores para um maior entendimento do fenômeno pesquisado.
ESTUDOS ORGANIZACIONAIS BASEADOS EM MICHEL DE CERTEAU: A PRODUÇÃO INTERNACIONAL ENTRE 2006 E 2015
Authors: Faria Arilton Marques , Leite-da-Silva Alfredo Rodrigues
Published: August 2017

Este estudo teve como objetivo discutir a produção científica internacional nos estudos organizacionais dos últimos dez anos, a qual usou as ideias de Michel de Certeau. Para isso, utilizou-se a bibliometria como estratégia metodológica. Analisou-se uma amostra final de 57 artigos a partir de três dimensões: aspectos gerais, aspectos metodológicos e aspectos temáticos. Os resultados mostram que o Reino Unido foi o país mais recorrente em termos de origem das instituições, dos autores e dos periódicos. Também se verificou que grande parte dos estudos foi do tipo empírico e qualitativo, com predomínio da estratégia do estudo de caso e da entrevista como técnica de coleta. Além disso, constatou-se que resistência foi a temática mais recorrente, tática foi o conceito mais usado e Michel Foucault e Pierre Bourdieu foram os teóricos mais articulados com Michel de Certeau. Acima de tudo, este artigo evidenciou que a característica marcante de Michel de Certeau, que é a crítica sobre a suposta tendência de submissão à manutenção do que está estabelecido como verdade, contamina a sua obra e contagia os estudos que a utilizam. Nesse sentido, concluiu-se que esse é um potencial do autor, com muitos resultados a oferecer, em vários temas dos estudos organizacionais.

Published: August 2017

The Two for One Twister (TFO) machine emits very disturbing noise and the noise exposes the workers while performing their tasks. The noise also lead to works stress. So, it is necessary to determine the relationship between the noise and work stress of TFO machine operators. This study  was  conducted  by measuring  the  noise  of  TFO  engine  with  Enviro-meter  and then correlating the noise and work stress with SPSS 16 software. Spearman correlation test results showed that a strong correlation between noise with work stress (p value = 0.042). In order to reduce the noise level that will decrease stress for workers, Fault Tree Analysis was conducted to determine the source of the noise. Based on the qualitative analysis of FTA, the causes of the noise were as follows: the lubricating oil was not applied, seal of oil valve leaked, bearing was not replaced (2 years economic life), the traveler was not replaced (10 days economic life), and the Doubling machine was troubled. Based on the quantitative analysis of the probability of job stress of TFO machine operator due to noise TFO machines from a known probability of 0.041, hence, the system was feasible for use.

„… wie im Himmel so auf Erden“ Die räumlichen Implikationen der Vergebungsbitte des matthäischen Vaterunsers
Authors: Blumenthal Christian
Published: August 2017

The question of the connection between human and divine forgiveness in the fifth petition of the Matthean version of the Lord’s Prayer has been widely discussed. The specific structuring function of this petition, however, has not yet been taken seriously into consideration. This study attempts to remedy this interpretative deficiency. It will be shown that this petition extends the prayer for an alignment of earthly and heavenly reality in Mt 6:10. Because in Mt 6:12 the praying person ascribes to himself the preceding act of forgiveness, he takes responsibility for the realization of this process of alignment “on earth as it is in heaven.”
Ein Rausch und seine Folgen. Parallelen zwischen der Erzählung von Noah als Weinbauer (Gen 9,20–27) und ihren Auslegungstraditionen und der Bilha-Episode in TestRub 3,11–15
Authors: Opferkuch Stefan
Published: August 2017

It is a matter of debate whether Bilha’s drunkenness in TestRub 3,13 is to be seen as an excuse for her being naked or as a form of misbehavior. The present article seeks to solve this problem by showing that the author of TestRub modeled his account of Gen 35,22a after Early Jewish and Rabbinic traditions concerning the story of Noah in the vineyard (Gen 9,20–27). It is argued that the parallels between the two stories and ancient traditions about Noah’s drunkenness and nakedness, where Noah’s conduct is often considered negatively, suggest that Bilha’s behavior in TestRub 3,11–15 is to be considered negatively as well.

This work presents the development of self-modifiable Intellectual Property (IP) modules for histogram calculation using the modelbased design technique provided by Xilinx System Generator. In this work, an analysis and a comparison among histogram calculation architectures are presented, selecting the best solution for the design flow used. Also, the paper emphasizes the use of generic architectures capable of been adjustable by a self configurable procedure to ensure a processing flow adequate to the application requirements. In addition, the implementation of a configurable IP module for histogram calculation using a model-based design flow is described and some implementation results are shown over a Xilinx FPGA Spartan-6 LX45.
Medio socioambiental y ecoturismo en la Reserva de la Biosfera de Los Tuxtlas (Veracruz, México): una posible nueva alternativa al desarrollo
Authors: Moreno Arriba Jesús
Published: August 2017

Desde un enfoque de trabajo transdisciplinar que conjuga métodos y técnicas característicos de la investigación geográfica y antropológica (geoantropología), en este artículo se ha constatado, documentado y analizado un proyecto no gubernamental de prácticas socioespaciales alternativas para la gestión de recursos ecoturísticos en la región de Los Tuxtlas y la Sierra de Santa Marta (Veracruz, México). Frente al modelo de desarrollo productivista y paternalista de las políticas públicas mexicanas y veracruzanas -que ha originado un grave deterioro del medio socioambiental-, estas experiencias, emanadas del ambientalismo social mexicano, se presentan como ejemplos de buenas prácticas para construir un nuevo modelo de desarrollo capaz de contribuir al mejoramiento de la precaria situación actual -ecológica, demográfica y socioeconómica- de las comunidades indígenas campesinas.
Riesgo de pérdida de los sistemas de producción agrícola tradicional por la amenaza turística en Occidente Cercano (Antioquia, Colombia)

El efecto del turismo sobre los sistemas de producción (SP) puede analizarse en términos de riesgo de pérdida y como producto de la amenaza y la vulnerabilidad. En el Occidente antioqueño el turismo es una actividad transformadora, por ello se evaluó si constituye una amenaza para los SP tradicionales y si estos están en riesgo. Se determinó la intensidad del turismo y la vulnerabilidad de seis SP tradicionales, considerando múltiples factores externos e internos. Se encontró que, efectivamente, el turismo representa un riesgo para los SP y que los más vulnerables son aquellos que usan tecnologías inadecuadas para las condiciones biofísicas, donde el operador no es propietario o donde falta relevo generacional. La investigación muestra que se requieren estrategias de planificación para promover un turismo con identidad cultural.
Paisaje y territorio en la playa Juan de Dios, Bahía Málaga, Pacífico colombiano (2005-2016): una aproximación desde la nueva geografía del turismo
Authors: Ospina Niño José Alejandro
Published: August 2017

La Reserva Natural Juan de Dios, ubicada en la Bahía de Málaga en el Pacífico colombiano, es el escenario de una dinámica turística particular en la que se ha configurado el paisaje y se ha construido el territorio sobre las bases del respeto por la naturaleza. El presente artículo da cuenta de la experiencia turística desde sus aristas física, social y ambiental. Dicho acercamiento se hace desde la nueva geografía del turismo, una postura que entiende el turismo como una práctica socioespacial compleja en la cual se enfatiza el componente cultural. Las principales conclusiones giran en torno a la importancia de reivindicar los estudios sobre el turismo desde una perspectiva humanística, así como demostrar la necesidad de abordarlos en mayor número y con enfoques distintos al puramente económico. Del mismo modo, el valor simbólico aparece como la principal característica desde la cual es pertinente trabajar las dinámicas de turismo y conservación del lugar objeto de estudio.
Szintaktikai sértések és a sértés nyelvtani elemei közötti távolság hatásának vizsgálata a magyar nyelvben

Háttér és célok

A szövegek megértéséhez elengedhetetlen a nyelvtani szerkezet feldolgozása. Kísérletünkben a helytelen nyelvtani szerkezet (szintaktika) feldolgozása során megjelenő eseményhez kötött agyi potenciálokat (EAP) vizsgáltuk, mely általában két komponensben jelenik meg: a bal anterior negativitás (LAN) és a P600. A LAN-t a morfoszintaktikai szabálysértés váltja ki. A P600-at a nyelvtani szerkezeti újrafeldolgozásához kötik, azaz nyelvtanilag helytelen, bonyolult vagy többértelmű információ feldolgozásakor jelenik meg. A többet vizsgált nyelvekkel ellentétben a magyar nyelvben az alany-állítmány egyeztetés sértése mellett a tárgy-állítmány egyeztetés sértése is megvalósítható. Az alany-állítmány egyeztetési sértés mellett két olyan sértést hoztunk létre, melyek az alany és a tárgy reorganizációját vonják maguk után: a „-t” tárgyrag elhagyásával a tárgyról, illetve annak az alanyhoz toldásával. Kutatásunkban arra kerestük a választ, hogy az alany-tárgy reorganizációs sértések eseteiben is megjelennek-e a tipikus EAP-komponensek, illetve az alany-állítmány sértéshez hasonló mintázatot mutatnak-e. Emellett arra is választ szerettünk volna kapni, hogy az egyeztetést meghatározó szavak közötti távolság befolyásolja-e ezeket komponenseket.

Módszer

20 egészséges felnőtt elektroenkefalográfiás vizsgálata során egy képernyőn szavanként jelentek meg a mondatok, melyeknek fele nyelvtanilag helyes, fele pedig helytelen volt. Háromféle sértést alkalmaztunk, és sértéseket meghatározó szavak közötti távolság 1–11 szó lehetett.

Eredmények

A három típusú sértés eltérő LAN-P600 mintázatot eredményezett, emellett a kétféle reorganizációs sértés sem mutatott egyforma EAP-mintázatot. Továbbá a nyelvtani elemzőrendszer érzékeny a sértést meghatározó két szó közötti távolságra.
A babaséma optimumának vizsgálata élettelen tárgyakon
Authors: Kiss-Leizer Márton
Published: August 2017

Konrad Lorenz etológus tárgyalta először, hogy bizonyos fizikai jellemzők, mint a nagy fej, a gömbölyded arc, a magas homlok, a kis orr és száj, valamint a nagy szem — amelyek a kisbabák arcának jellemzői — vonzónak, aranyosnak hatnak, és gondozóviselkedésre irányuló motivációt aktiválnak a felnőttekben. Az általa megalkotott babaséma („Kinderschema”) fogalom azóta már széles körben bebizonyította a hatását a humán percepcióra, hiszen többek között orientálja a figyelmet, lokálissá teszi az észlelést, preferenciát vált ki, sőt akár élettelen tárgyakra vonatkoztatva is megváltoztatja ítéletünket. A kutatások fókuszpontján azonban mindeddig kívül esett, hogy vajon a babaarc jellegeit túlzó mértékben kihangsúlyozó képek hogyan befolyásolják az emberek aranyosságészlelését. Képszerkesztő technikák segítségével tizenhárom autóról készült képet alakítottunk ki, amelyek a babaséma jellegeit a nullától a körülbelül háromszoros torzításig tartalmazták. A vizsgálatban részt vevő 259 felnőtt személy feladata az volt, hogy megítélje, hogy az adott autót mennyire tartja aranyosnak, illetve egyes képpárok esetében ki kellett választania, hogy a megjelenő gépjárművek közül melyiket választaná. Az aranyosságítélet feladatra adott válaszok egy fordított U alakú haranggörbét rajzoltak ki, melynek csúcsán a babaséma arányait megközelítőleg kétszeresen torzító optimális eset áll, amely ennek értelmében az emberekből a lehető legerőteljesebb reakciót váltja ki. A választásos feladatrész adataiból azt állapítottuk meg, hogy — a férfiakkal összehasonlítva — a nők számára valamivel fontosabb tényező az autóvásárlás során, hogy az autó megjelenése aranyosnak hasson, bár a válaszok eloszlását tekintve egyik nem sem választotta szívesen az aranyosabbnak ítélt autót. A vizsgálat eredményei új fejezetet nyitnak a babaséma kutatásának irányában, hiszen az optimum számos ígéretes kutatási és alkalmazási lehetőségre világít rá.

Kutatásunk célja az SPSI—A (Social Problem Solving Inventory—Adolescent, Frauenknecht és Black, 2010) adaptálása volt 12 és 16 évesek körében (N=540). A kérdőív konvergens és diszkriminatív validitásának vizsgálatához az SPSI—R-t (Social Problem Solving Inventory—Revised, D’Zurilla és mtsai, 2002), a Davis által kidolgozott empátiakérdőívet (Interpersonal Reactivity Index, 1980), valamint a Spielberger- féle vonás - és állapotszorongást mérő kérdőívet (State-Trait Anxiety Inventory for Children, Spielberger és mtsai, 1973) használtuk. Az eredeti kérdőív 10 faktoros, 64 kijelentésből áll. A feltáró és a megerősítő faktorelemzés eredményei alapján a magyar változat — SPSI—A(H) – 54 tételt tartalmaz, melyek 11 faktorba csoportosulnak (az eredeti Gondolatok faktor kijelentései elkülönülnek a Pozitív gondolatok és a Negatív gondolatok faktorba). A kérdőív mind a 12, mind a 16 évesek mintáján jó megbízhatósággal (a Cronbach-α sorrendben 0,81 és 0,83) mér. Az eredmények alapján az SPSI—A(H)-t alkalmasnak tartjuk a problémamegoldással kapcsolatos automatikus gondolatok, a problémamegoldáshoz való érzelmi, gondolati viszonyulás, az elkerülés, a probléma meghatározása, a célmeghatározás, az alternatív megoldási módok keresése, a következmények végiggondolása, illetve a nem megfelelő megoldás esetében a gondolatok, teendők újraszervezése és az utólagos kiértékelés mérésére.
