The effect of the through-thickness moisture content gradient on the moisture accelerated creep of paperboard: Hygro-viscoelastic modeling approach
Authors: Sorvari Joonas , Leppänen Teemu , Silvennoinen Jukka
Published: May 2018

Paper-based materials are viscous materials, the time-dependent behavior of which depends strongly on moisture content. Particularly the creep of paperboard containers under compressive forces is greatly affected by changes in the relative humidity. In the present paper, we examine the creep behavior of paperboard under cyclic humidity conditions using the finite element method. Especially the shape and rate of the through-thickness moisture content gradient on moisture accelerated creep are studied. An isotropic hygro-viscoelastic constitutive law is used for paperboard. The results of the simulations are compared with experiments. It is concluded that the through-thickness moisture gradients have a great impact on the moisture accelerated creep of paperboard. Furthermore, the results show that depending on the direction of external load the through-thickness moisture content gradient may increase or decrease creep rate.

Authors: Zhang Zhengjian , Zhang Qilian , Zhang Mingzhi , Huang Ruquan , Han Yutong
Published: May 2018

In order to improve its printability the effects of pigment sizing on printability and coating structure of decorative base paper were investigated. Silica, styrene-acrylic emulsion (SAE) and cationic starch were used to prepare the pigment sizing solution. After been pigment sized, the physical performances, printing properties and coating structure of the paper were determined. Pigment sizing had a more obvious effect on the physical properties, printability and coating structure. The tensile strength was increased by 26.99 %, the print-surf roughness was decreased by 17.98 %, the water absorption height was increased by 8.51 %. The color density was improved, the percentage of dots loss decreased by 21.33 %, the roundness of dots increased by 43.33 % and thus better printing effect was achieved. The water receptivity and absorption of decorative base paper could be improved by pigment sizing under the appropriate binder-to-pigment ratio. SEM and three-dimensional image showed that silica/cationic starch/SAE had filled the pores of paper and formed an uniform coating structure. Considering the improvement of the physical properties, printability and coating structure, the best ratio of binder-to-pigment was identified as 70:30.
Control strategies for refiners Part I: Soft sensors for CD-refiner control
Authors: Karlström Anders , Hill Jan
Published: May 2018

Internal variables in (C)TMP-refining processes (e. g. temperature, consistency, fiber residence time, backward flowing steam and forces acting upon the chips and pulp) are defined as physical states obtained in different parts of the refining zones. In short, they differ from the traditional external variables (e. g. dilution water feed rate and specific energy) which are not obtained from measurements or physical models of the process in the refining zone. The internal variables are the backbone of physical models and are used in this paper as soft sensors for advanced process control. Besides the shape of the temperature profile, the position of the maximum temperature and the shape of the consistency profiles inside the refining zones are important to control as they are directly linked to the development of different pulp and handsheet properties. To illustrate the capability when using combined modeling and control strategies, the concept is applied on a full scale CD82 refiner. This means both temperature and consistency control in the flat zone and the conical zone, together with an overall estimator for fiber development. Finally, in this paper it is shown that the production can be increased significantly without changing the refiner motor load nor violating the pulp property specification.
Strengthening effect of polyelectrolyte multilayers on highly filled paper
Authors: Lee Jegon , Youn Hye Jung
Published: May 2018

Polyelectrolyte multilayering (PEM) treatment is regarded as one of the surface modification techniques to increase paper strength. In this study, the strengthening effect of PEM treatment of highly filled paper was investigated. PEM treatment was performed on both fiber and filler with cationic starch and anionic polyacrylamide systems. Both approaches provided an improvement in the strength of filled paper. However, the strengthening effect of PEM treatment on fibers became weaker as filler content increased, whilst the PEM treatment on fillers was more effective in improving the strength of the highly filled paper. This was because PEM treatment on fillers improved bonding strength between fiber and filler as well as bonding strength between fillers. This was confirmed by the evaluation of specific debonding factor between fiber and filler, and the measurement of the breaking strength of dense film composed of fillers.
Rethinking the Role of Invited Inferencing in Change from the Perspective of Interactional Texts
Authors: Traugott Elizabeth Closs
Published: May 2018

The hypothesis that “invited inferences” are factors in change and challenges to it are reviewed. In light of recent work on historical construction grammar and interactional discourse analysis, I suggest that at least three types of inferences play a role in interactional contexts: local inferences associated with specific expressions; discourse structuring inferences pertaining to factors like coherence, backgrounding and foregrounding; and turn-taking inferences associated with turn relevant positions. A case study tests this suggestion: the development of discourse structuring uses of a family of Look expressions. Turn-taking has been regarded as a trigger in related changes. However, in this case not turn-taking, but rather a profile shift associated with non-use of complementizers is hypothesized to be a crucial enabling factor.
Inferential Practices in Social Interaction: A Conversation-Analytic Account
Authors: Deppermann Arnulf
Published: May 2018

This paper argues that conversation analysis has largely neglected the fact that meaning in interaction relies on inferences to a high degree. Participants treat each other as cognitive agents, who imply and infer meanings, which are often consequential for interactional progression. Based on the study of audio- and video-recordings from German talk-in-interaction, the paper argues that inferences matter to social interaction in at least three ways. They can be explicitly formulated; they can be (conventionally) indexed, but not formulated; or they may be neither indexed nor formulated yet would be needed for the correct understanding of a turn. The last variety of inferences usually remain tacit, but are needed for smooth interactional progression. Inferences in this case become an observable discursive phenomenon if misunderstandings are treated by the explication of correct (accepted) and wrong (unaccepted) inferences. The understanding of referential terms, analepsis, and ellipsis regularly rely on inferences. Formulations, third-position repairs, and fourth-position explications of erroneous inferences are practices of explicating inferences. There are conventional linguistic means like discourse markers, connectives, and response particles that index specific kinds of inferences. These practices belong to a larger class of inferential practices, which play an important role for indexing and accomplishing intersubjectivity in talk in interaction.
Effects of ultrasonic injection molding conditions on the plate processing characteristics of PMMA
Authors: Yang Yi-Jen , Huang Chung-Ching
Published: May 2018

Polymer processing is a crucial and diverse field in the manufacturing industry. We investigated the process characteristics and effects of injection molding using ultrasonic vibration. An ultrasonic device was installed in an injection mold; polymer was directly vibrated during injection. An ultrasonic oscillation device 45 mm in diameter was placed in the cavity and used to vibrate a poly(methyl methacrylate) melt at 19 kHz. The amplitude of the acoustic unit was set at 15 μm for the measurements. Moreover, cavity pressure sensors were positioned at the front and rear sides of the vibration region to determine the melt flow behavior under ultrasonic-assisted injection molding conditions. Because of the absorption of ultrasonic energy, local heat was generated inside the resin, thus improving the flow characteristics of the melt. Moreover, the melt flow behavior around the skin layer was changed; the molecular orientation and high shear effect were reduced. Furthermore, the freezing rate of the melt was reduced; thus, the amount of melt pressure lost through the cavity was decreased and the residual stress inside the injection-molded component generated during the photoelastic stress analysis was lower.
Measurement of cross sections and isomeric cross-section ratios for the (n,2n) reactions on 85,87Rb in energies between 13 and 15 MeV
Authors: Luo Junhua , Jiang Li , He Long
Published: May 2018

The (n,2n) cross sections and their isomeric cross-section ratios (σm/σg) in the neutron energy range 13–15 MeV have been measured for 85,87Rb by an activation and off-line γ-ray spectrometric technique using the Pd-300 Neutron Generator at the Chinese Academy of Engineering Physics (CAEP). The natural Rb samples and Nb monitor foils were activated together to determine the reaction cross section and the incident neutron flux. The neutrons were produced via the 3H(d,n)4He reaction. The pure cross section of the ground-state was derived from the absolute cross section of the metastable state and the residual nuclear decay analysis. The 85Rb(n,2n)84m,gRb and 87Rb(n,2n)86m,gRb reaction excitation functions and their isomeric cross-section ratios were also calculated theoretically using the TALYS-1.8 code with different level density options. Results are discussed and compared with the corresponding literature data.
Drei Haselnüsse für Aschenbrödel
Authors: Retzlaff Steffen
Published: May 2018

‚Three Wishes for Cinderella‘ (Tři oříšky pro Popelku / Drei Haselnüsse für Aschenbrödel) is one of the most successful fairy tale films in Czech and German TV. Produced in 1973, it is shown up to now regularly around Christmas in both countries. Every year around the same time, at Moritzburg Castle near Dresden, which has been chosen as place of the ball in the movie, one can see a special Cinderella exhibition. In his paper the author investigates the question of the success of this film. He presents the conditions of the Czech-German joint production during the time of the so called normalisation after the Prague Spring. He compares the story and figures with its literary models (Božena Němcová, Brothers Grimm), and discusses some theories about the modernity of characters, especially of Cinderella as a modern emancipated woman. The core of the paper is the analysis of the narrative structure itself, which may be considered as the secret to the success of the movie.
Von drei translatorischen Nüssen des Aschenbrödels
Authors: Hrdinová Eva Maria
Published: May 2018

The paper deals with the translation of fairy tales on the basis of cultural and language pairs (according to Christiane Nord) as well as on the basis of the Kollers Theory of equivalence. This article deals specifically with the Grimm fairy tales in numerous Czech translations and also with the Czech-German fairy tale collection Vladimír Mikolášek’s. Both corpora show parallels and differences, both in content and in form.

Concrete problems, such as the equivalent lexicon or the stylistical specifics are discussed. Consideration is also given to updating and modernizing tendencies, differences between the corpora, as well as to the respective Grimm translations. Summarizing the paper, it can be said that culture is very important for the translation of fairy tales and minding cultural differences contributes to an adequate and successful translation.
Colorless green ideas do sleep furiously: gradient acceptability and the nature of the grammar
Authors: Sprouse Jon , Yankama Beracah , Indurkhya Sagar , Fong Sandiway , Berwick Robert C.
Published: May 2018

In their recent paper, Lau, Clark, and Lappin explore the idea that the probability of the occurrence of word strings can form the basis of an adequate theory of grammar (Lau, Jey H., Alexander Clark & 15 Shalom Lappin. 2017. Grammaticality, acceptability, and probability: A prob- abilistic view of linguistic knowledge. Cognitive Science 41(5):1201–1241). To make their case, they present the results of correlating the output of several probabilistic models trained solely on naturally occurring sentences with the gradient acceptability judgments that humans report for ungrammatical sentences derived from roundtrip machine translation errors. In this paper, we first explore the logic of the Lau et al. argument, both in terms of the choice of evaluation metric (gradient acceptability), and in the choice of test data set (machine translation errors on random sentences from a corpus). We then present our own series of studies intended to allow for a better comparison between LCL’s models and existing grammatical theories. We evaluate two of LCL’s probabilistic models (trigrams and recurrent neural network) against three data sets (taken from journal articles, a textbook, and Chomsky’s famouscolorless-green-ideassentence), using three evaluation metrics (LCL’s gradience metric, a categorical version of the metric, and the experimental-logic metric used in the syntax literature). Our results suggest there are very real, measurable cost-benefit tradeoffs inherent in LCL’s models across the three evaluation metrics. The gain in explanation of gradience (between 13% and 31% of gradience) is offset by losses in the other two metrics: a 43%-49% loss in coverage based on a categorical metric of explaining acceptability, and a loss of 12%-35% in explaining experimentally-defined phenomena. This suggests that anyone wishing to pursue LCL’s models as competitors with existing syntactic theories must either be satisfied with this tradeoff, or modify the models to capture the phenomena that are not currently captured.
Ancient Egyptian Concepts of Bodily Decay in the Old Kingdom Part 1, PT 684
Authors: Eaton Katherine
Published: May 2018

Old Kingdom descriptions of bodily decay are surrounded by assertions of revivification and the maintenance of a proper offering ritual. Thus, the contexts of lines describing bodily decay are first examined, focusing on Pyramid Text (PT) Utterance 684. The problems of preventing the decay of the corpse, and curing conditions of the living body associated with decay were interrelated in ancient Egyptian thought. Already in the Old Kingdom, terminology surrounding wet, drippy decay (r
ḏ
w, fdt, ḥ
wꜢ and ḥ
wꜢꜢ.t) was clear and well developed; sometimes incorporated into the offering ritual through association with libations; and paralleled in medical literature. In contrast, terminology which appears to refer to dry decay (jmk, rpw) is rare, and does not have more general uses outside of mortuary literature.
Quantifying intermolecular interactions for isoindole derivatives: substituent effect vs. crystal packing
Authors: Chęcińska Lilianna , Jóźwiak Andrzej , Ciechańska Magdalena , Paulmann Carsten , Holstein Julian J. , Dittrich Birger , Małecka Magdalena
Published: May 2018

The aim of the study was to examine noncovalent interactions in considerably different crystal packings of three isoindole compounds. Their structures were compared to three other closely-related derivatives described earlier in the literature. Here we discuss the crystal structures in the context of the hydrogen-bonded motifs and other weak interactions. The hierarchy of investigated intermolecular interactions was examined in a quantitative manner through pairwise interaction energies and energy framework analysis.
A study on the reaction of 3-alkyl(aryl)imidazo[1,5-a]pyridines with ninhydrin

Published: May 2018

The reaction of 3-alkyl(aryl)imidazo[1,5-a]pyridines (1) with ninhydrin in dichloromethane at room temperature delivered good yields of the respective 2-hydroxy-2-(imidazo[1,5-a]pyridine-1-yl)indene-1,3-diones. In the presence of dimethyl acetylenedicarboxylate (DMAD), this uncatalyzed electrophilic substitution reaction, involving C-1 (in 1) and the central C=O (in ninhydrin), takes precedence over the three-component 1,4-dipolar cycloaddition reaction. This selectivity is probably due to the higher electrophilicity of the carbonyl carbon-2 in ninhydrin as compared to that of the sp-carbon atoms in DMAD, augmented with the high nucleophilicity of carbon-1 in 1.

Authors: Chaimowitz Gary A , Furimsky Ivana , Singh Natashia , Kolawole Olubukola
Published: May 2018

Involuntary treatment orders to restore competence to stand trial under the Criminal Code of Canada provide an opportunity to explore variables associated with restoration. We reviewed all 199 defendants assessed for fitness to stand trial in a catchment area of 2.3 million people over a two-year period, of which 26 were admitted to a regional psychiatric program under a treatment order. All had a psychotic disorder, and 92% (n=24) were restored to competence within the 60-day order period. No specific factors were associated with restoration. Unlike other studies, our study found that psychosis did not militate against restoration of competence.
The next generation of risk assessment and management

Published: May 2018

Big data and analytics are rapidly changing health care and enabling a degree of measurement and quality improvement not previously seen. For a variety of reasons including the limited number of quality indicators in mental health care, psychiatry has been late to the game. Use of technology to measure, monitor, and assess risk and change, would have a significant impact for key stakeholders including patients, care providers, and the community. Analytics offer an opportunity to increase our understanding of the psychiatric populations, target effective programs and interventions, and direct more personalized care at the critical intersection of risk assessment and prediction – risk management. The electronic Hamilton Anatomy of Risk Management (eHARM) aims to harness the capabilities afforded by data analytics to enhance the assessment, monitoring, and management of risk at the clinical interface.

Published: May 2018

Fluoretação da água de abastecimento público é a adição de compostos de flúor nas estações de tratamento da água como uma das formas de prevenção da cárie dentária.  Ainda que a fluoretação das águas seja reconhecidamente eficaz na prevenção da cárie dentária, e mesmo que a Organização Mundial da Saúde (OMS) siga recomendando-a como medida estratégica de saúde pública, há questionamentos quanto à sua efetividade em contextos em que as populações estão expostas a múltiplas fontes de flúor. O objetivo desta revisão foi apresentar alguns pontos sobre fluoretação da água no Brasil.  Para além de saber se a fluoretação das águas de abastecimento público é eficaz ou não, é relevante seguir avaliando se essa tecnologia de saúde pública é ou não efetiva na prevenção da cárie, sobretudo em contextos socioeconômicos marcados por desigualdades, como é o caso do Brasil. Somente com a análise detalhada de todos os argumentos poder-se-á chegar a um posicionamento sólido em relação ao tema, com conclusões mais acuradas.
Self-Knowledge in Personality Disorders: An Emotion-Focused Perspective
Authors: Kramer Ueli , Pascual-Leone Antonio
Published: May 2018

Emotional knowledge about one's own and others’ emotional experience are central features of mental health and may be characteristic of therapeutic processes leading to good outcome. Clients with personality disorders (PDs) often lack in their ability to access and accept emotional experiences, or to reflect on emotion and use it in adaptive ways. The present theoretical and clinical review discusses self-knowledge, and lack thereof, in personality disorders, from an emotion-focused perspective. A first section differentiates between two fundamental types of meaning construction processing. The second section describes, from an integrative therapy perspective, how self-knowledge may be facilitated in psychotherapy by the client–therapist interaction. A subsequent section discusses lack of awareness of one's own emotions in the construction of meaning associated with PDs. The final section describes initial studies that demonstrate change occurring in constructing emotional self-knowledge as a correlate of treatment. The concepts of the review are illustrated throughout with three clinical cases of PD.
Expressivism, Psychic Health, and the First-Person Stance
Authors: Leite Adam
Published: May 2018

This article addresses the psychotherapeutically important phenomenon of relating first-personally to one's own emotion, belief, desire, or other attitude. The fundamental theoretical challenge is to understand how one can relate to one's attitudes as one's attitudes without occupying a position that is alienated from them. Philosophical questions in this area are significantly illuminated by considering certain clinically manifested vicissitudes and pathologies of the first-person. The article interprets the first-person relation in terms of a complex set of functional capacities: the capacity to occupy the subjective perspective of the attitude as conscious subject; the capacity to both self-ascribe the attitude and articulate its content, in ways that are expressive manifestations of the attitude; and various capacities involved in relating to one's state as an attitude. The resultant conception of the first-person stance accommodates a range of clinically significant phenomena and suggests a multidimensional specification of one key aspect of psychological health.
Facial Emotion Recognition and Social-Cognitive Correlates of Narcissistic Features

Published: May 2018

Narcissistic personality disorder (NPD) is associated with both seeming indifference and hypersensitivity to social feedback. This study evaluated whether rejection sensitivity and empathic difficulties in NPD are accounted for by altered facial emotion recognition (FER). Two-hundred non-clinical individuals self-reported NPD features, rejection sensitivity, and empathy and performed an FER task assessing the ability to determine the presence or absence of an emotion when viewing neutral and negative facial stimuli presented at varying emotional intensities (25%, 50%, 75%). Those with higher NPD features were faster at accurately recognizing neutral and low, 25%–intensity emotional stimuli. This response pattern mediated the association between NPD features and increased anger about rejection. Thus, individuals with high NPD traits are hypervigilant toward subtle negative emotions and neutral expressions; this may explain their tendency to experience intense angry feelings when facing the possibility that the others would not meet their need for acceptance.
Readers’ Insensitivity to Tense Revealed: No Differences in Mental Simulation During Reading of Present and Past Tense Stories
Authors: Eekhof Lynn S. , Eerland Anita , Willems Roel M.
Published: May 2018

While the importance of mental simulation during literary reading has long been recognized, we know little about the factors that determine when, what, and how much readers mentally simulate. Here we investigate the influence of a specific text characteristic, namely verb tense (present vs. past), on mental simulation during literary reading. Verbs usually denote the actions and events that take place in narratives and hence it is hypothesized that verb tense will influence the amount of mental simulation elicited in readers. Although the present tense is traditionally considered to be more “vivid”, this study is one of the first to experimentally assess this claim. We recorded eye-movements while subjects read stories in the past or present tense and collected data regarding self-reported levels of mental simulation, transportation and appreciation. We found no influence of tense on any of the offline measures. The eye-tracking data showed a slightly more complex pattern. Although we did not find a main effect of sensorimotor simulation content on reading times, we were able to link the degree to which subjects slowed down when reading simulation eliciting content to offline measures of attention and transportation, but this effect did not interact with the tense of the story. Unexpectedly, we found a main effect of tense on reading times per word, with past tense stories eliciting longer first fixation durations and gaze durations. However, we were unable to link this effect to any of the offline measures. In sum, this study suggests that tense does not play a substantial role in the process of mental simulation elicited by literary stories.
Splicing dysregulation as a driver of breast cancer
Authors: Read Abigail , Natrajan Rachael
Published: May 2018

Breast cancer is known to be a heterogeneous disease driven by a large repertoire of molecular abnormalities, which contribute to its diverse clinical behaviour. Despite the success of targeted therapy approaches for breast cancer patient management, there is still a lack of the molecular understanding of aggressive forms of the disease and clinical management of these patients remains difficult. The advent of high-throughput sequencing technologies has paved the way for a more complete understanding of the molecular make-up of the breast cancer genome. As such, it is becoming apparent that disruption of canonical splicing within breast cancer governs its clinical progression. In this review, we discuss the role of dysregulation of spliceosomal component genes and associated factors in the progression of breast cancer, their role in therapy resistance and the use of quantitative isoform expression as potential prognostic and predictive biomarkers with a particular focus on oestrogen receptor-positive breast cancer.

Exploring the Relationship Between Innovative Work Behavior and Leadership: Moderating Effect of Locus of Control
Authors: Škudienė Vida , Augutytė-Kvedaravičienė Ieva , Demeško Natalija , Suchockis Anicetas
Published: May 2018

The topic of innovative work behavior has recently received an increased amount of attention due to a highly competitive, complex, and dynamic economic environment. This paper examines the effect of the leadership styles (transformational and transactional) on innovative work behavior. Moreover, the study explores moderation effects of internal and external locus of control in the relationship between transformational and transactional leadership and innovative work behavior. The findings indicate the importance of alignment of the transformational and transactional leadership styles with employees’ locus of control while aiming to transform organizational and individual resources into innovative outcomes. More specifically, the results show that contingent reward has stronger relationship with internal locus of control, whereas passive management by exception has stronger relation to external locus of control proving that enhancement of external employee motivation may boost employee innovative work behavior. Therefore, this study confirms that different leadership practices show specific linkage to certain locus of control type subordinates, meaning that their effectiveness can rise, if applied to this specific type of individuals. The research contributes to the existing knowledge of leadership styles and locus of control role in managing innovative work behavior and overall to the knowledge about how innovation can be managed in modern organizations.
The Impact of Cultural Distance on the Performance of Foreign Subsidiaries: Evidence From the Korean Market
Authors: Park Hyunjun , Han Kyungsu , Joon Woojin
Published: May 2018

This study investigates whether the cultural distance between Korea and the home countries of foreign subsidiaries in Korea affects the subsidiaries’ financial performance. It contributes to the literature on international business in that it sheds light on cultural distance, a well-established but somewhat neglected concept in international business. Unlike most of the previous studies that have used cultural distance as a control or moderating variable, this study uses it as an independent variable in the context of globalization through foreign direct investments in Korea. Focusing on the possible positive side of broad cultural distance, we hypothesize that the performances of foreign subsidiaries are likely to be better when the cultural distance between their home countries and Korea increases. To test our hypothesis, we have conducted an empirical analysis, using data collected from 472 foreign subsidiaries doing business in Korea. The results support our argument that cultural distance has a positive impact on financial performance. This study finds that having cultural similarities with a foreign market does not guarantee success. Instead, it shows that firms can gain opportunities when incorporating in a foreign national market with broad cultural distance.
Associations between the HEXACO model of personality and gambling involvement, motivations to gamble, and gambling severity in young adult gamblers
Authors: McGrath Daniel S. , Neilson Tessa , Lee Kibeom , Rash Christina L. , Rad Mandana
Published: May 2018

Background and aims

Substantial research has examined the role of personality in disordered gambling. The predominant model in this work has been the five-factor model (FFM) of personality. In this study, we examined the personality correlates of gambling engagement and gambling severity using a six-dimensional framework known as the HEXACO model of personality, which incorporates FFM characteristics with the addition of honesty–humility. In addition, the potential mediating role of gambling motives in the personality and gambling severity relationship was explored.

Methods

A sample of undergraduate gamblers (n = 183) and non-gamblers (n = 143) completed self-report measures of the Problem Gambling Severity Index (PGSI) and the Gambling Motives Questionnaire-Financial, as well as self- and observer report forms of the HEXACO-100.

Results

Logistic regression results revealed that scores on honesty–humility were positively associated with non-gambling over gambling status. Furthermore, it was also found that honesty–humility, agreeableness, and conscientiousness were each uniquely associated with PGSI severity scores. The results of the mediational analyses suggest that each personality factor has different gambling motivational paths leading to PGSI gambling severity.

Discussion and conclusions

The findings of this study contribute to the literature on behavioral addictions by providing an increased understanding of individual personality factors associated with likelihood of gambling, overall gambling severity, and gambling motives. Ultimately, these findings suggest that the honesty–humility dimension may be a target for the prevention efforts against problematic gambling outcomes.
Cientistas, militares e burocratas: O Desenvolvimento da Arpanet e o Sistema Norte-Americano de Inovação
Authors: Martins Ladeira João Damasceno
Published: May 2018

O artigo revisita a discussão sobre o desenvolvimento da Arpanet e das primeiras tecnologias para redes de computadores de um ponto de vista que se distancia do debate orientado segundo as ideias de cibercultura e de tecnologias de inteligência. A partir de uma análise institucional, investiga-se a coalizão de forças necessária à constituição de tal projeto, na expectativa de entender a internet como inovação inserida na trajetória para aprimoramento tecnológico construída pelos EUA no pós-guerra, e não como uma experiência disruptiva. Assim, investigam-se as relações entre a Arpa e o complexo industrial-militar, construídas pela associação entre elite tecnocrática e centro de decisão estatal, frisando o papel dos “homens de ciência” e o tipo de contribuição por eles oferecida.

Redemocratização e reposicionamento de instâncias reguladoras da comunicação: disputas pelo controle da mídia no Brasil
Authors: Paganotti Ivan
Published: May 2018

O artigo aborda o desmonte da estrutura estatal de censura durante a abertura democrática no Brasil no final dos anos 1980, avaliando como novas entidades de regulação procuraram distanciar-se das antigas engrenagens de censura estatal. O método de análise parte da sistematização das instâncias regulatórias proposto por Sousa, Trützchler, Fidalgo & Lameiras (2013), ampliando o mecanismo de comparação internacional para uma nova avaliação inter-setorial e histórica das instâncias que regulam diferentes setores da comunicação no Brasil. A avaliação das estruturas, composições, funções e práticas de regulação de cada entidade apontou para a importância de expandir a metodologia original, abarcando também sua formação e movimentos de resistência e adesão às novas instâncias de controle. A multiplicação de instâncias parciais de reduzido poder coercitivo é resultado de um processo de fortalecimento das empresas comunicadoras ante o Estado, fenômeno impactado pelo modelo negociado de abertura democrática no qual concessões públicas de meios de comunicação foram usadas como moeda de troca para garantir o apoio entre elites locais na transição política nacional.

Esta pesquisa empírica desenvolve-se a partir da análise sobre a cobertura feita pelo grupo Mídia Ninja das ações relativas ao Movimento de Ocupação, que tomou mais de mil instituições de ensino em todo o Brasil em 2016. Esse movimento se tornou símbolo de resistência à PEC 241/55, elaborada pelo governo Temer para congelar os gastos na saúde e educação por 20 anos. A coleta resulta do monitoramento feito pelo Observatório de Mídia da Universidade Federal do Pará (UFPA), que somente na fanpage do Mídia Ninja no Facebook contabilizou 565 postagens sobre as ocupações nos períodos de 07 a 16 e 22 a 27 de novembro de 2016. Adotando-se critérios quanti e qualitativos, analisou-se 50 postagens publicadas nessa fanpage, considerada um espaço de enfrentamento e crítica ao discurso hegemômico. A partir dos estudos de Downing (2002), Martín-Barbero (2009) e Motta (2013), dentre outros teóricos, procura-se identificar e compreender os modos de narrar presentes no conteúdo produzido pelo coletivo em sua fanpage, a fim de perceber especificidades do jornalismo no contexto do ativismo midiático. Os principais resultados desta pesquisa apontam para uma narrativa jornalística pautada pelo ativismo, cuja construção é marcada pelo olhar não apenas de quem produz a notícia, mas também de quem vivencia os fatos.

Background Hypercalciuria can result from activation of the basolateral calcium-sensing receptor (CaSR), which in the thick ascending limb of Henle’s loop controls Ca2+ excretion and NaCl reabsorption in response to extracellular Ca2+. However, the function of CaSR in the regulation of NaCl reabsorption in the distal convoluted tubule (DCT) is unknown. We hypothesized that CaSR in this location is involved in activating the thiazide-sensitive NaCl cotransporter (NCC) to prevent NaCl loss.

Methods We used a combination of in vitro and in vivo models to examine the effects of CaSR on NCC activity. Because the KLHL3-WNK4-SPAK pathway is involved in regulating NaCl reabsorption in the DCT, we assessed the involvement of this pathway as well.

Results Thiazide-sensitive 22Na+ uptake assays in Xenopus laevis oocytes revealed that NCC activity increased in a WNK4-dependent manner upon activation of CaSR with Gd3+. In HEK293 cells, treatment with the calcimimetic R-568 stimulated SPAK phosphorylation only in the presence of WNK4. The WNK4 inhibitor WNK463 also prevented this effect. Furthermore, CaSR activation in HEK293 cells led to phosphorylation of KLHL3 and WNK4 and increased WNK4 abundance and activity. Finally, acute oral administration of R-568 in mice led to the phosphorylation of NCC.

Conclusions Activation of CaSR can increase NCC activity via the WNK4-SPAK pathway. It is possible that activation of CaSR by Ca2+ in the apical membrane of the DCT increases NaCl reabsorption by NCC, with the consequent, well known decrease of Ca2+ reabsorption, further promoting hypercalciuria.

O objetivo deste estudo é analisar a Cadeia da Cajucultura no processo de desenvolvimento regional, a aglomeração produtiva no sentido de Arranjos Produtivos Locais e sua importância no processo de dinamização do território Açu-Mossoró no Rio Grande do Norte. O método utilizado na pesquisa foi o Estudo do Caso, visando alcançar todas as unidades familiares de beneficiamento da castanha do caju no ano de 2011. Foi feito o censo por meio de entrevistas a 230 produtores em quatro municípios do território: Açu, Serra do Mel, Mossoró e Porto do Mangue. Como resultado, foi possível verificar a frágil estruturação organizacional em todos os municípios do território, apesar do beneficiamento da castanha se apresentar uma atividade viável e importante para a dinâmica de desenvolvimento regional, visto que foi possível calcular uma receita de aproximadamente R$ 20 milhões no ano. Por fim, foi possível estruturar um retrato da atual situação da cadeia produtiva da cajucultura no território Açu-Mossoró, mesmo com seus gargalos de empobrecimento das relações de trabalho e influência do atravessador no acesso a mercados.
Análise da capacidade de discriminação de critérios da avaliação da pós-graduação na área de Planejamento Urbano e Regional e Demografia da Capes
Authors: Carmo Roberto Luiz do , Shimoda Eduardo
Published: May 2018

Na avaliação dos programas de pós-graduação pela CAPES, em função dos critérios adotados para enquadramento dos programas nos 5 estratos de nota, os itens demonstram diferentes capacidades de discriminar os programas. O presente artigo tem como objetivos propor uma metodologia para avaliar a capacidade de discriminação dos itens e identificar os itens cujos critérios poderiam ser rediscutidos para tentar melhorar a capacidade de discriminar os programas. Para tal, foram analisadas as frequências de programas nos estratos em cada um dos itens, tomando por base as informações presentes no documento de área de Planejamento Urbano e Regional e Demografia do triênio 2010-2012. Para avaliação da capacidade de discriminação de cada item, foi proposta a utilização dos seguintes parâmetros estatísticos: média, amplitude, desvio-padrão, grau de assimetria e desvio médio em relação à distribuição uniforme. Os itens, com base nestes parâmetros estatísticos, foram classificados como tendo nenhuma, baixa, média e alta capacidade de discriminação. Ressalta-se que os resultados poderiam servir como subsídio preliminar para discussão, no âmbito da área, para possível implementação de critérios objetivos nos itens.

Published: May 2018

O estímulo à constituição de arranjos produtivos tem sido uma política de governos do Rio Grande do Sul para enfrentar as vulnerabilidades do desenvolvimento nas diferentes regiões do Estado. O objetivo deste trabalho é apresentar estratégias e ações para o plano de desenvolvimento do APL Agroindústria Familiar da Região Celeiro a partir de um diagnóstico sobre a região e o APL. O diagnóstico levou em consideração dados secundários sobre a região e, em especial, dados primários gerados a partir de observações diretas e entrevistas semiestruturadas com responsáveis por todas as organizações diretamente ligadas ao arranjo e lideranças locais. Apesar do uso de dados quantitativos, o estudo segue uma abordagem qualitativa baseada principalmente na interpretação das informações coletadas e geradas. A construção do plano de desenvolvimento seguiu uma metodologia participativa e estratégica, com efetivo envolvimento dos atores locais para estabelecer uma visão partilhada sobre os rumos do desenvolvimento, bem como a definição das ações necessárias para atingi-lo. Os resultados reforçam seis estratégias, cada uma com um conjunto de ações, no sentido de reforçar o arranjo local como uma alternativa para enfrentar os problemas sociais e econômicos da região.

Published: May 2018

Este trabalho avaliou a política de Arranjos Produtivos Locais (APL) no Rio Grande do Sul. Foi analisado se os setores dos municípios que possuem APL tiveram algum impacto sobre o nível de emprego e renda em relação àqueles que não possuem. Os dados foram retirados do site da RAIS utilizando-se 672 classes CNAE 2.0 para todos os municípios do estado no período de 2006 a 2014. O método utilizado foi o de diferenças-em-diferenças aplicando-se matching e efeito-fixo para os setores e o tempo. O arranjo Moveleiro da Serra Gaúcha e o APL de Pedras, Gemas e Joias foram os únicos que obtiveram resultados positivos e significativos para o nível de emprego. Na análise da remuneração média, nove APLs apresentaram efeitos positivos e com significância.
