Transportation modal choice in coolant importation through total costs minimization: a case study
Authors: Leite Marcela De Souza , Santos Stephanie Conceição , Garo Junior Wagner Roberto
Published: June 2018

Transportation plays a very significant role when it comes to the costs of a company representing on average 60% of logistics costs, so its management is very important for any company. The transportation modal choice is one of the most important transportation decisions. The purpose of this article is to select the transportation mode which is able to minimize total costs, and consistent with the objectives of customer service on the coolant import, which is used in plasma cutting machines. With the installation of a distribution center in Brazil and the professionalization of the logistics department of the company, it was decided to re-evaluate the transportation mode previously chosen to import some items. To determine the best mode of transportation was used basic compensation costs, in other words the cost compensation of using the shuttle service to the indirect cost of inventory related to the modal performance. Through the study, it was possible to observe it may be possible to save up to 73% on the coolant international transportation by changing the transportation mode used by the company.
Hittite Geographers: Geographical Perceptions and Practices in Hittite Anatolia
Authors: Gerçek N. İlgi
Published: June 2018

Hittite archives are remarkably rich in geographical data. A diverse array of documents has yielded, aside from thousands of geographical names (of towns, territories, mountains, and rivers), detailed descriptions of the Hittite state’s frontiers and depictions of landscape and topography. Historical geography has, as a result, occupied a central place in Hittitological research since the beginnings of the field. The primary aim of scholarship in this area has been to locate (precisely) or localize (approximately) regions, towns, and other geographical features, matching Hittite geographical names with archaeological sites, unexcavated mounds, and—whenever possible—with geographical names from the classical period. At the same time, comparatively little work has been done on geographical thinking in Hittite Anatolia: how and for what purpose(s) was geographical information collected, organized, and presented? How did those who produce the texts imagine their world and their homeland, “the Land of Hatti?” How did they characterize other lands and peoples they came into contact with? Concentrating on these questions, the present paper aims to extract from Hittite written sources their writers’ geographical conceptions and practices. It is argued that the acquisition and management of geographical information was an essential component of the Hittite Empire’s administrative infrastructure and that geographical knowledge was central to the creation of a Hittite homeland.
Neural Network-Based Architecture for Sentiment Analysis in Indian Languages
Authors: Bhargava Rupal , Arora Shivangi , Sharma Yashvardhan
Published: June 2018

Sentiment analysis refers to determining the polarity of the opinions represented by text. The paper proposes an approach to determine the sentiments of tweets in one of the Indian languages (Hindi, Bengali, and Tamil). Thirty-nine sequential models have been created using three different neural network layers [recurrent neural networks (RNNs), long short-term memory (LSTM), convolutional neural network (CNN)] with optimum parameter settings (to avoid over-fitting and error accumulation). These sequential models have been investigated for each of the three languages. The proposed sequential models are experimented to identify how the hidden layers affect the overall performance of the approach. A comparison has also been performed with existing approaches to find out if neural networks have an added advantage over traditional machine learning techniques.

Object and consciousness in dialectical materialism. A contribution to the theory of social communication
Authors: Andrzejewski Bolesław
Published: June 2018

The aim of the paper is to describe one of the theories of man, then of those regarding language and communication. There are many concepts related to these categories. Most of them define man as an independent being from outside, significant external influences. Dialectical materialism goes a different way in which man is a part of material world. Moreover, our language and communication have their roots and exist in the objective environment.
Jürgen Habermas’s postconventional constractarianism as cosmopolitan constitutionalism
Authors: Cern Karolina M.
Published: June 2018

In the course of this paper article I shall depict in what way Jürgen Habermas’s application of the discourse theory to the democratic polity transforms the contractarian theoretical framework, presuming, however, that the reader is familiar with the general theoretical framework and the basic concepts characteristic for this political tradition. Moreover, I will also show that the relevance of this transformation consists in delivering a justification of a kind of cosmopolitan constitutionalism.
Strategic actions according to Jürgen Habermas – some critical remarks from the transcendental-pragmatic procedure viewpoint
Authors: Filipiak Magdalena
Published: June 2018

The purpose of this paper is to analyze the primacy of communicative rationality in relation to other forms of rationality and to determine the status of openly strategic actions in the concept of Jürgen Habermas. In the theory of communicative actions, Habermas focuses on actions secretively strategic, recognizing them as “parasitic” in relation to communicative actions and explains the prevalence of communicative actions on the grounds of the theory of speech acts, in particular the concept of illocutionary force, the category of “social binding force”, or practice in the lifeworld. By the same, Karl-Otto Apel challenges Habermas that he has skipped explicitly strategic class of actions, which entails the inadequacy of the justification for the status of communicative rationality. This raises a doubt – why should non-strategic actions take precedence over strategic ones? Karl-Otto Apel replies to this question with the help of transcendental-pragmatic procedure of an ultimate justification.
Manuel Castells’ theory of information society as media theory
Authors: Kirtiklis Kęstas
Published: June 2018

The present article deals with one of the most elaborated theories of information society, proposed by Manuel Castells. Castells defines the present social landscape as the Information Age, in which human societies perform their activities in a new technological paradigm and argues that this landscape was brought about by the revolution of information and communication technologies (ICT) at the second half of the 20th century. I argue that Castells first and foremost theorizes these new ICT (in the vein of media theorist Marshall Mc-Luhan) and discerns their three main features – network logic, timeless time and space of flows which are visible only in the interaction of media and society. Therefore, Castells’ ICT / media theory serves as a kind of methodological framework for his theory of the information society.

Metasurfaces and their applications
Authors: Li Aobo , Singh Shreya , Sievenpiper Dan
Published: June 2018

Metasurfaces are a topic of significant research and are used in various applications due to their unique ability to manipulate electromagnetic waves in microwave and optical frequencies. These artificial sheet materials, which are usually composed of metallic patches or dielectric etchings in planar or multi-layer configurations with subwavelength thickness, have the advantages of light weight, ease of fabrication, and ability to control wave propagation both on the surface and in the surrounding free space. Recent progress in the field has been classified by application and reviewed in this article. Starting with the development of frequency-selective surfaces and metamaterials, the unique capabilities of different kinds of metasurfaces have been highlighted. Surface impedance can be varied and manipulated by patterning the metasurface unit cells, which has broad applications in surface wave absorbers and surface waveguides. They also enable beam shaping in both transmission and reflection. Another important application is to radiate in a leaky wave mode as an antenna. Other applications of metasurfaces include cloaking, polarizers, and modulators. The controllable surface refractive index provided by metasurfaces can also be applied to lenses. When active and non-linear components are added to traditional metasurfaces, exceptional tunability and switching ability are enabled. Finally, metasurfaces allow applications in new forms of imaging.
A reliable analytical approach for a fractional model of advection-dispersion equation
Authors: Singh Jagdev , Secer Aydin , Swroop Ram , Kumar Devendra
Published: June 2018

Empirical investigations of solute fate and carrying in streams and rivers often contain inventive liberate of solutes at an upstream perimeter for a finite interval of time. An analysis of various worth references on surface-water-grade mathematical formulation reveals that the logical solution to the continual-parameter advection- dispersion problem for this type of boundary state has been generally missed. In this work, we study theq-fractional homotopy analysis transform method (q-FHATM) to find the analytical and approximate solutions of space-time arbitrary order advection-dispersion equations with nonlocal effects. The diagrammatical representation is done by using Maple package, which enhance the discretion and stability of family ofq-FHATM series solutions of fractional advection-dispersion equations. The efficiency of the applied technique is demonstrated by using three numerical examples of space- and time-fractional advection-dispersion equations.
Nonlinear generalized Jordan (σ, Γ)-derivations on triangular algebras
Authors: Alkenani Ahmad N. , Ashraf Mohammad , Jabeen Aisha
Published: June 2018

Let R be a commutative ring with identity element, A and B be unital algebras over R and let M be (A,B)-bimodule which is faithful as a left A-module and also faithful as a right B-module. Suppose that A = Tri(A,M,B) is a triangular algebra which is 2-torsion free and σ, Γ be automorphisms of A. A map δ:A→A (not necessarily linear) is called a multiplicative generalized (σ, Γ)-derivation (resp. multiplicative generalized Jordan (σ, Γ)-derivation) on A associated with a (σ, Γ)-derivation (resp. Jordan (σ, Γ)-derivation) d on A if δ(xy) = δ(x)r(y) + σ(x)d(y) (resp. σ(x2) = δ(x)r(x) + δ(x)d(x)) holds for all x, y Є A. In the present paper it is shown that if δ:A→A is a multiplicative generalized Jordan (σ, Γ)-derivation on A, then δ is an additive generalized (σ, Γ)-derivation on A.

The aim of this paper is twofold. First, we show a connection between the Lagrangian- Grassmannian variety geometry defined over a finite field with q elements and the q-ary Low-Density Parity- Check codes. Second, considering the Lagrangian-Grassmannian variety as a linear section of the Grassmannian variety, we prove that there is a unique linear homogeneous polynomials family, up to linear combination, such that annuls the set of its rational points.
Abriendo closings in bilingual radio speech: Discourse strategies, code-switching, and the interactive construction of broadcast structures and institutional identity
Authors: Tseng Amelia
Published: June 2018

Radio highlights the linguistic construction of institutional identity: it privileges presenter speech, as DJs use language to represent not only the self but also the show, and ultimately the station’s identity to the listening audience for commercial purposes. The relationship between show structure and stylistic practice in interaction offers insights into identity construction and audience relationships in institutional settings. This qualitative study investigates the linguistic construction of closing sequences in bilingual radio discourse, examining the relationship between DJ speech and the interactional construction of closing structures in 18 report- and chat-genre closings from 95.1 Latino Vibe. Findings indicate that closing structures are genre-specific, with the less-formal chat genre integrating elements of media and conversational closings. Code-switching is genre-sensitive and plays a multifaceted functional, relational, and representational role, ranging from constructing show structures to audience affiliation and a formulaic type of “verbal branding.” Ultimately, closing sequences and code-switching relate to broader institutional goals of station representation and audience engagement. The article sheds light on the relationship between interaction-level discourse moves, institutionalized identity construction, and the development of interactional structures through talk; and highlights the added dimensions that bilingual speech strategies contribute to these practices.

Shooting for Perfection: Hawaii’s Goal of 100% Renewable Energy Use
Authors: Solomon Barry D. , Wellstead Adam M.
Published: June 2018

In the United States, 29 states, Washington, D.C. and three territories have adopted a mandatory Renewable Portfolio Standard (RPS) for their electric power systems, while eight states and one territory have set renewable energy goals. Many foreign nations have adopted an RPS as well. Thus far, almost all RPSs across the United States have met their interim goals with targets and timetables that vary widely. Hawaii’s RPS is the most ambitious, with a 100% target set for 2045 (though Vermont set a 75% target for 2032). This paper provides a case study of the Hawai’i RPS. The paper focuses on geographical issues and perspectives that may tease out the course of the states’ electricity future: sensitivity to climate change, population distribution, interisland rivalries, as well as the need for greater energy storage and complementary policies. An important complexity is the challenge of meeting electricity demand on six separate Hawaiian Islands (because of the lack of an interisland transmission cable), although all of them have substantial renewable energy resources.

Published: June 2018

Context

Von Hippel–Lindau (VHL) disease manifests as a variety of benign and malignant neoplasms. Previous studies of VHL disease have documented several genotype–phenotype correlations; however, many such correlations are still unknown. Increased identification of new mutations and patients with previously described mutations will allow us to better understand how VHL mutations influence disease phenotypes.

Patients and design

A total of 45 individuals from five unrelated families were evaluated, of which 21 patients were either diagnosed with VHL disease or showed strong evidence related to this disease. We compared the patients’ gene sequencing results with their medical records including CT or MRI scans, eye examinations and laboratory/pathological examinations. Patients were also interviewed to obtain information regarding their family history.

Results

We identified four missense mutations: c.239G>T (p.Ser80Ile), linked with VHL Type 2B, was associated with renal cell carcinoma, pheochromocytoma and hemangioma in the cerebellum; c.232A>T (p.Asn78Tyr) manifested as RCC alone and likely caused VHL Type 1; c.500G>A (p.Arg167Gln) mutation was more likely to cause VHL Type 2 than Type 1 as it preferentially induced Pheo and HB in the retina, cerebellum and spinal cord; c.293A>G (p.Try98Cys) was associated with Pheo and thus likely induced VHL Type 2.

Conclusions

Characterizing VHL disease genotype–phenotype correlations can enhance the ability to predict the risk of individual patients developing different VHL-related phenotypes. Ultimately, such insight will improve the diagnostics, surveillance and treatment of VHL patients.

Precis

Four missense mutations in VHL have been identified in 21 individuals when five unrelated Chinese families with VHL disease were analyzed; VHL mutations are highly associated with unique disease phenotypes.
THE EFFECTS OF DRIED FAECAL SLUDGE AND MUNICIPAL WASTE CO-COMPOST ON MICROBIAL LOAD AND YIELD OF CABBAGE (Brassica oleracea L. var. capitata) AND LETTUCE (Lactuca sativa)
Authors: Torgbo Selorm , Annang Quaye Emmanuel , Apusiga Adongo Thomas , Opoku Nelson
Published: June 2018

Municipal waste management has been of major concern to many developing countries and is presently one of the subjects under discussion due to rapid industrialization and population growth. Most of these municipal wastes have the potential of being recycled and use in crop production. They are gradually becoming a problem in Ghana instead of being used for purposes to benefit human kind. In this study, dried faecal sludge and municipal waste co-compost was used as an organic fertilizer to cultivate cabbage and lettuce to assess its effects on their microbial load and yield. The yields of vegetables increased significantly with the application of recommended doses of the co-compost. The analysis of microbial load on the vegetables also showed significantly low microbial load on vegetables cultivated on co-compost plots followed by the chemical fertilizer and control. The presences of faecal coliforms such as Salmonella spp., Shigella spp., Escherichia coli, and Klebsiella spp. were confirmed in all. The performance of vegetable cultivated on plots treated with the co-compost makes it a good source of plant nutrients to be recommended to farmers. This could also serve as prudent strategy for managing municipal waste and faecal sludge to avoid impact of unscientific disposal on public health and quality of life.
POLYMORPHISM IN SUGAR BEET VARIETIES AND HYBRIDS IN CELL SELECTION FOR RESISTANCE TO ABIOTIC FACTORS
Authors: Klyachenko Oksana , Prysiazhniuk Larysa
Published: June 2018

In the article, the results on the development of cell selection scheme for sugar beet genotypes resistant to high temperature are presented. In terms of increase in the callus diameter and the ability to regenerate plants, lines of high-temperature resistant genotypes Yaltushkivskyi MS 72, Ukrainian MS 70, Ukrainian MS 72 and Katiusha found to be promising for breeding. Experiments confirmed that 5-7 times increased proline content is typical of the temperature resistant lines. We investigated the molecular and genetic polymorphism in sugar beet genotypes using RAPD and SSR analyses. Fourteen alleles were identified and analyzed by four RAPD markers and five alleles by GZM 086 marker. Cluster analysis using DNA markers shows that Ukrainian MS 72 and Ivanivskyi MS 33 are the most similar genotypes, and they are found in the same cluster. It was determined that the temperature resistant sugar beet genotypes Yaltushkivskyi MS 72, Ukrainian MS 70, Ukrainian MS 72 and Katiusha are genetically distant and therefore can be used to create heterotic hybrids.
ISOLATION AND PAPAIN DIGESTION OF NOVEL ANTIFUNGAL PEPTIDES FROM RED RADISH (RAPHANUS RAPHANISTRUM SUBSP SATIVUS) AND ANALYSIS OF SELECTIVE CYTOTOXICITY FOR CANCER TREATMENT
Authors: Janardhanan Yashaswini , Nandakumar Varier Mamta
Published: June 2018

Treating cancer with chemotherapy is accompanied with side effects and drug resistance by cancer cells which call for alternative anticancer agents such as cationic antimicrobial peptides. In specific, antifungal peptides were chosen for cytotoxicity analysis due to their deteriorating effects on fungi (eukaryotic cells). Novel peptides were isolated and analysed from red radish seeds. Water soaked seeds were ground with phosphate buffer (pH 7) and the antifungal assay was carried out and an inhibition zone of 0.5±0.2 mm was noticed for 50 μl of the extract at 1 mg/ml concentration. The study was extended further, by digestion with papain, trypsin and pepsin with appropriate buffer and pH of which papain digests of red radish seeds produced a zone of inhibition of 1.00±0.2 mm at 500 μg/ml concentration, approximately. This sample was processed with a 3 kDa cut off membrane and the filtrate was confirmed for its antifungal activity (MIC 32 μg/ml). Further, for size confirmation, the sample was subjected to MALDI- TOF-MS analysis, and a peak was obtained at 1680 Da (1.68 kDa). To check the anticancer activity of the antifungal peptides obtained, the sample was tested on HeLa cell lines by method of MTT Assay and significant cell death was obtained at MIC 12.5 μg/ml which increased with higher concentrations of the sample. Thus, it is confirmed that red radish seed extract digested with papain is effective in inhibiting the growth of both fungal and cancer cell lines making them a good therapeutic agent against cancer.
Idiomaticidade, familiaridade e informação prévia no processamento de expressões idiomáticas do PB
Authors: De Oliveira Gomes Barreto Sara , Marcilese Mercedes , Avelar de Oliveira Ágata Jéssica
Published: June 2018

Expressões idiomáticas são comumente caracterizadas como combinações fixas e não-composicionais nas quais o sentido figurado não constitui uma função da soma das partes; seu grau de composicionalidade, entretanto, é variável. Este artigo investiga a compreensão de expressões idiomáticas do tipo verbo-complemento no português brasileiro (ex. “pintar o sete”, “passar a bola”). Buscamos avaliar em que medida propriedades internas e externas das expressões podem influenciar no processamento das mesmas. Reportamos os resultados de um experimento de leitura automonitorada (conduzido por meio de uma maze task), no qual o segmento crítico corresponde à complementação do verbo: idiomático vs. literal (ex. abrir o coração/ a porta). Os resultados revelaram efeitos estatisticamente significativos das três variáveis investigadas, sugerindo que o grau de idiomaticidade, a familiaridade do falante com a expressão e a informação prévia afetam o processamento das expressões e, portanto, devem ser considerados num modelo que busque explicitar a representação, o acesso e a compreensão dessas estruturas.

Published: June 2018

O presente estudo objetivou avaliar e estimular a consciência fonológica em indivíduos com síndrome de Down. Os 24 participantes, divididos em três grupos, foram testados em suas habilidades de consciência fonológica e, em seguida, os grupos experimentais (um com desenvolvimento típico e um com síndrome de Down) realizaram um programa de estimulação dessas habilidades que teve a duração de seis semanas. Como resultado, os dois grupos experimentais foram significativamente melhores no pós teste, devido à eficiência da estimulação, e apresentaram melhor desempenho que o grupo controle (sem a síndrome). Além disso, o grupo com síndrome de Down, após a estimulação, obteve um aprimoramento superior que o grupo experimental sem a síndrome, provavelmente por terem realizado as atividades individualmente. Destaca-se o fato de que as atividades de estimulação foram especialmente desenvolvidas em função das dificuldades de memória, de atenção e de linguagem expressiva normalmente vinculadas à síndrome. Algumas reflexões sobre opções metodológicas são sugeridas em relação à avaliação e ao ensino de populações atípicas.
Envelhecimento sadio, Comprometimento Cognitivo Leve e doença de Alzheimer: um estudo das estratégias comunicativas na narrativa oral
Authors: Jerônimo Gislaine Machado
Published: June 2018

O aumento de casos de Comprometimento Cognitivo Leve (CCL) e de doença de Alzheimer (DA) leva ao questionamento sobre as habilidades cognitivas e linguísticas comprometidas. A literatura, de modo geral, aborda os prejuízos na comunicação destas populações, sendo pouco investigadas as habilidades preservadas. Assim, este estudo objetiva analisar as estratégias comunicativas (ECs) presentes na produção de narrativa oral desses indivíduos, bem como verificar o impacto da variável escolaridade no esempenho da mesma atividade em idosos saudáveis. Participaram do estudo 95 idosos, os quais produziram uma narrativa oral baseada em uma sequência de figuras, The Dog Story (LE BOUEF, 1976). Os resultados mostraram que idosos com CCL e DA fizeram mais uso de ECs do que o grupo controle, ao passo que idosos saudáveis com alta escolaridade utilizaram menos. Portanto, as ECs mostraram-se um apoio à comunicação no CCL e na DA, assim como a escolaridade evidenciou-se um importante marcador de reserva cognitiva no envelhecimento sadio.

Este artigo trata do processamento de sentenças com interrogativas-QU de sujeito e de objeto em português brasileiro1 (PB). Especificamente, investigou-se a Assimetria Sujeito-Objeto nesse tipo de sentença, partindo-se de resultados anteriores com a técnica de leitura automonitorada (OLIVEIRA; MAIA, 2010; OLIVEIRA, 2013). Foram utilizadas as técnicas de rastreamento ocular (eyetracking) e eletroencefalografia (EEG) como ferramentas de diagnóstico do processamento linguístico em tempo real. O objetivo era buscar evidências sobre o modus operandi do parser durante o processamento das funções de sujeito e de objeto em sentenças interrogativas-QU no PB e verificar se há discrepâncias entre as técnicas utilizadas. Os resultados revelam diferenças interessantes, permitindo discernir os níveis de análise representacional, algorítmico e implementacional, na direção da clássica proposta de Marr (1982).
On E-semiabundant semigroups with a multiplicative restriction transversal
Authors: Wang Shoufeng
Published: June 2018

Multiplicative inverse transversals of regular semigroups were introduced by Blyth and McFadden in 1982. Since then, regular semigroups with an inverse transversal and their generalizations, such as regular semigroups with an orthodox transversal and abundant semigroups with an ample transversal, are investigated extensively in literature. On the other hand, restriction semigroups are generalizations of inverse semigroups in the class of non-regular semigroups. In this paper we initiate the investigations of E-semiabundant semigroups by using the ideal of "transversals". More precisely, we first introduce multiplicative restriction transversals for E-semiabundant semigroups and obtain some basic properties of E-semiabundant semigroups containing a multiplicative restriction transver- sal. Then we provide a construction method for E-semiabundant semigroups containing a multiplicative restriction transversal by using the Munn semigroup of an admissible quadruple and a restriction semigroup under some natural conditions. Our construction is similar to Hall's spined product construction of an orthodox semigroup. As a corollary, we obtain a new construction of a regular semigroup with a multiplicative inverse transversal and an abundant semigroup having a multiplicative ample transversal, which enriches the corresponding results obtained by Blyth-McFadden and El-Qallali, respectively.
On the Erdős-Mordell inequality for normed planes and spaces
Authors: Ghandehari Mostafa , Martini Horst
Published: June 2018

In the Euclidean plane, the Erdős-Mordell inequality indicates that the sum of distances of an interior point of a triangle T to its vertices is larger than or equal to twice the sum of distances to the sides of T. We extend this theorem to arbitrary (normed or) Minkowski planes, and we generalize in an analogous way some other related inequalities, e.g. referring to polygons. We also derive Minkowskian analogues of Erdős-Mordell inequalities for tetrahedra and n-dimensional simplices. Finally, some related inequalities are obtained which additionally involve total edge-lengths of simplices.

On (A)-rings and strong (A)-rings issued from amalgamations
Authors: Mahdou Najib , Moutui Moutu Abdou Salam
Published: June 2018

A ring R has the (A)-property (resp., strong (A)-property) if every finitely generated ideal of R consisting entirely of zero divisors (resp., every finitely generated ideal of R generated by a finite number of zero-divisors elements of R) has a nonzero annihilator. The class of commutative rings with property (A) is quite large; for example, Noetherian rings, rings whose prime ideals are maximal, the polynomial ring R[x] and rings whose total ring of quotients are von Neumann regular. Let f : A → B be a ring homomorphism and J be an ideal of B. In this paper, we investigate when the (A)-property and strong (A)-property are satisfied by the amalgamation of rings denoted by A ⋈fJ, introduced by D'Anna, Finocchiaro and Fontana in [3]. Our aim is to construct new original classes of (A)-rings that are not strong (A)-rings, (A)-rings that are not Noetherian and (A)-rings whose total ring of quotients are not Von Neumann regular rings.
“Pornographic binges” as a key characteristic of males seeking treatment for compulsive sexual behaviors: Qualitative and quantitative 10-week-long diary assessment
Authors: Wordecha Małgorzata , Wilk Mateusz , Kowalewska Ewelina , Skorko Maciej , Łapiński Adam , Gola Mateusz
Published: June 2018

Background and aims

Compulsive sexual behaviors (CSBs) are an important clinical and social issue. Despite the increasing number of studies, some of CSB’s aspects remain under-investigated. Here, we explore the nature of CSB, such as binge pornography use and masturbation (PuM), and verify the correspondence between self-perceived factors leading to such behavior with its measures obtained in a diary assessment.

Methods

Semi-structuralized interviews with nine treatment-seeking males aged 22–37 years (M = 31.7, SD = 4.85) were followed by a questionnaire and a 10-week-long diary assessment, allowing us to acquire real-life daily patterns of CSB.

Results

Six out of nine subjects experienced binge (multiple hours or times a day) PuM. All subjects presented a high level of anxiety and perceived PuM as a way to regulate mood and stress. Data collected in the diary assessment uncovered a high diversity in the patterns of sexual behaviors (such as frequency of regular and binge PuM) and its correlates. Binge PuM was related to decreased mood and/or increased stress or anxiety. The causal relation between these correlates remains undetermined.

Discussion and conclusions

Binge PuM seems to be one of the most characteristic behavior among males who are seeking treatment for CSB and is related to the feeling of losing control over one’s sexual activity. CSB individuals indicate a variety of binge triggers. Also, diary assessment data indicate that specific correlates of binge PuM (decreased mood, increased stress, and anxiety) differ between subjects. It suggests the existence of significant individual differences in binge PuM behaviors, and a need to study these differences, as it may help guide personalized treatment.

In this paper, I examine recent influential accounts of the bushfire knowledge and practicesof Aboriginal peoples and their ancestors on the Australian continent, drawingattention to how these accounts accord with problematic and ecomodernist aspects ofcontemporary bushfire management discourse. Developing a two-part critique of thisdiscourse, I suggest both that we should accord the ecological contributions of Aboriginalpeoples and their ancestors significantly greater esteem, and that the recent accountspotentially limit the grounds for contemporary Aboriginal peoples' engagements in themanagement of their territories or "Country".

Computer-aided design/computer-aided manufacturing (CAD-CAM) technology permits the angular correction of screw emergence into the prosthesis; however, there is lack of controlled clinical studies that assess the frequency of technical complications in angled screw channel restorations. This controlled clinical study was designed to assess technical incidences in angled screw channel restorations. Patients who underwent placement of implant prosthesis between November 2014 and December 2015 were screened. The patients were selected if they received a prosthesis with up to 30° correction of the prosthesis screw emergence and had at least 1 nonangulated prosthesis (screw retained). All prostheses were located completely/partially in the posterior region. The frequency of technical complications was the principal variable. A total of 52 patients with a mean age of 62 ± 10 years participated, with a total of 110 prostheses (55 in the test group and 55 in the control group). A total of 11 technical complications occurred (7 in the test group and 4 in the control group). These differences were not statistically significant. All prostheses in both groups survived the follow-up. The correction of the screw emergence into the prosthesis has not increased the risk of technical complications in CAD-CAM implant prostheses.

Devido aos benefícios percebidos pelas organizações na adoção de uma arquitetura modular, esta vem sendo muito utilizada para a inovação de produtos, principalmente nos setores que a concorrência e a competitividade são mais intensas. Nesse sentido, o objetivo deste trabalho é identificar, com base em uma análise da literatura, os benefícios do uso da arquitetura modular e os trade-offs existentes com relação ao projeto modular. Para tal, foi feita uma revisão sistemática da literatura visando identificar publicações que investigaram a relação entre a adoção do projeto modular e o desempenho de inovação. O presente trabalho apresenta os principais benefícios do uso da arquitetura modular como, por exemplo, custo e tempo de produção; trade-offs do projeto modular que influenciam na inovação de produtos, como no caso de proteção da propriedade intelectual e impacto ambiental dos produtos. As oportunidades para pesquisas futuras identificadas relacionam-se, principalmente, a necessidade de estudos empíricos e que avaliem as restrições do uso da modularidade. Verifica-se a importância de avaliar as vantagens e desvantagens do uso do projeto modular de acordo com as estratégias da organização e conclui-se que as pesquisas direcionadas para a verificação dos impactos ambientais das inovações modulares, assumem importante papel no contexto atual.

O cenário competitivo para as organizações industriais vem ao longo do tempo sofrendo modificações, caracterizadas pela crescente competitividade em custo, qualidade, confiabilidade, agilidade e mais recentemente por fatores ambientais e sociais. Este trabalho tem por objetivo propor um modelo de análise exploratória para avaliar a competitividade em sustentabilidade de organizações industriais. Para efeito deste trabalho a competitividade em sustentabilidade será medida em quatro fatores críticos: econômico, serviço, ambiental e social. O modelo propõe o agrupamento das organizações industriais em clusters, classificando-as quanto à adoção de práticas de manufatura enxuta, gestão ambiental e recursos humanos, distribuindo-as em quadrantes de acordo com a produção maior ou menor de desperdícios e resíduos em seus processos de manufatura. A aderência do modelo se fez para uma amostra de organizações industriais de autopeças e montadoras de veículos automotores. O trabalho se classifica como sendo de natureza aplicada, exploratória pela análise de agrupamento, qualitativa e utilizando-se do método survey. Destaca-se na conclusão que a aplicação do modelo apresentou uma preponderância dos fatores críticos de competitividade em sustentabilidade nas dimensões econômica e serviços. Por outro lado 37,5% das organizações autopeças estão agrupadas em clusters que levam à redução de desperdícios e resíduos, com práticas em manufatura enxuta e gestão ambiental ajustando-se aos fatores de competitividade em sustentabilidade das montadoras de veículos automotores.

O desafio de constantes mudanças no ambiente de negócios, no crescimento populacional, bem como nas alterações na legislação e nos padrões de consumo conduzem as empresas a buscarem soluções mais sustentáveis e que atendam às necessidades cada vez mais específicas dos consumidores. Abordagens denominadas como Sistemas Produto-Serviço (Product-service Systems - PSS) têm sido consideradas como uma resposta inovadora a esse desafio, por apresentarem soluções completas, com produtos físicos e serviços que trazem benefícios aos consumidores e fornecedores, ao mesmo tempo em que otimizam recursos e mitigam impactos ambientais. A partir de uma revisão sistemática da literatura, aspectos relevantes sobre a inovação de sistemas tradicionais para modelos PSS são apresentados e discutidos. Tais aspectos compreendem os métodos de transição para PSS, fatores que influenciam na transição, métodos para avaliação do PSS, bem como os facilitadores a sua implementação. Os resultados demonstram fatores indispensáveis para implementação do PSS, tais como: compreensão dos conceitos do PSS, participação dos diversos stakeholders, organização interna com conhecimento de serviços e inserção da dimensão social. Finalmente, são apresentadas sugestões para trabalhos futuros, a partir das lacunas de pesquisa identificadas e limitações dos estudos existentes.
Impacto da política de incentivo regulatório para qualidade do fornecimento de energia na estratégia de investimento no setor elétrico
Authors: Andrade Fernando , Rodrigues de Farias Filho Jose
Published: June 2018

O presente trabalho trata de um estudo multi-casos que tem como objetivo avaliar o impacto da política de incentivos regulatórios para melhoria da qualidade do fornecimento de energia elétrica (Fator Q, implantada pela ANEEL em 2011) na estratégia de investimento do setor elétrico brasileiro. Neste sentido, aplicou-se um modelo de avaliação econômica em duas distribuidoras de energia elétrica com diferentes condições de qualidade do fornecimento. A avaliação foi realizada em dezoito cenários, com e sem Fator Q e com investimento realizado em cada um dos cinco anos do ciclo tarifário de uma das distribuidoras e em cada um dos quatro anos do ciclo tarifário da outra. O resultado indica que o incentivo regulatório (Fator Q) para melhoria da qualidade do fornecimento de energia elétrica não altera de forma significativa a rentabilidade dos investimentos em projetos para este fim. Desta forma, o incentivo regulatório para melhoraria da qualidade do fornecimento de energia elétrica (Fator Q) pode não impactar de forma significativa a estratégia de investimento das distribuidoras de energia elétrica no Brasil.

A gestão de marketing por meio de suas técnicas de pesquisas permite um maior entendimento das variáveis externas que influenciam na organização, através desta metodologia é possível avaliar o ambiente competitivo, a qual está inserida. Desta forma, o presente trabalho teve como objetivo empregar o método AHP para melhor identificar as ações de marketing de uma empresa que fornece materiais de construção localizada na região central do Rio Grande do Sul. Os 4 P’s de marketing (Produto, Preço, Praça e Promoção) foram empregados relacionando com o método AHP. Partindo disto, realizou-se um estudo de caso exploratório/descritivo. Os resultados alcançados revelaram que o critério que possui maior grau de importância é o Produto (0,50108), o qual o gerente enfatiza sua importância perante os demais, sendo que esta variável deve atender satisfatoriamente as necessidades dos clientes. O efeito de todo esse processo permite a organização trabalhar seus pontos fracos, e melhorar os pontos fortes, assim aumentando o nível de satisfação dos clientes e colocando-se em vantagens das demais concorrentes.

Background Gabapentin and pregabalin are used to manage neuropathic pain, pruritus, and restless legs syndrome in patients on hemodialysis. These patients may be especially predisposed to complications related to these agents, which are renally cleared, but data regarding the risk thereof are lacking.

Methods From the US Renal Data System, we identified 140,899 Medicare-covered adults receiving hemodialysis with Part D coverage in 2011. Using Cox regression models in which we adjusted for demographics, comorbidities, duration of exposure, number of medications, and use of potentially confounding concomitant medications, we investigated the association between gabapentin and pregabalin, modeled as separate time-varying exposures, and time to first emergency room visit or hospitalization for altered mental status, fall, and fracture. We evaluated risk according to daily dose categories: gabapentin (>0–100, >100–200, >200–300, and >300 mg) and pregabalin (>0–100 and >100 mg).

Results In 2011, 19% and 4% of patients received gabapentin and pregabalin, respectively. Sixty-eight percent of gabapentin or pregabalin users had a diagnosis of neuropathic pain, pruritus, or restless legs syndrome. Gabapentin was associated with 50%, 55%, and 38% higher hazards of altered mental status, fall, and fracture, respectively, in the highest dose category, but even lower dosing was associated with a higher hazard of altered mental status (31%–41%) and fall (26%–30%). Pregabalin was associated with up to 51% and 68% higher hazards of altered mental status and fall, respectively.

Conclusions Gabapentin and pregabalin should be used judiciously in patients on hemodialysis, and research to identify the most optimal dosing is warranted.
