Тензорные инварианты и интегрирование дифференциальных уравнений
Authors: Kozlov Valery Vasil'evich
Published: January 2019

Обсуждается связь тензорных инвариантов систем дифференциальных уравнений с проблемой их точного интегрирования. Доказана общая теорема об интегрируемости динамических систем, допускающих полный набор интегральных инвариантов по Картану. Наличие инвариантной $1$-формы связано с возможностью представления динамической системы в гамильтоновой форме (возможно, с вырожденной симплектической структурой). Эта общая идея продемонстрирована на примере линейных систем дифференциальных уравнений. Введено общее понятие флагов тензорных инвариантов. Установлены общие соотношения между показателями Ковалевской квазиоднородных систем дифференциальных уравнений и флагами квазиоднородных тензорных инвариантов известной структуры. Результаты общего характера применены, в частности, для доказательства ветвления общего решения уравнений вращения твердого тела в случае Горячева-Чаплыгина.

$Q$-обучение в стохастической игре Штакельберга между неинформированным лидером и наивным ведомым
Authors: Rokhlin Dmitry Borisovich
Published: January 2019

Рассматривается игра между лидером и ведомым, в которой действия игроков влияют на стохастическую динамику процесса состояний $x_t$, $t\in\mathbf Z_+$. Игроки наблюдают свои выигрыши и состояние $x_t$ системы. Переходное ядро процесса $x_t$ и функции доходов оппонента им неизвестны. На каждом шаге игры лидер выбирает действие $a_t$ первым. При выборе действия $b_t$ ведомому известно $a_t$. Действия ведомого лидеру неизвестны (неинформированный лидер).
Каждый из игроков стремится максимизировать дисконтированный критерий, применяя алгоритм $Q$-обучения. Рандомизированные стратегии игроков определяются распределениями Больцмана, зависящими от $Q$-функций, обновляемых в процессе обучения. Особенность рассматриваемого алгоритма состоит в том, что при обновлении своей $Q$-функции ведомый считает, что действие лидера в следующем состоянии будет таким же, как в текущем (наивный ведомый). Показано, что для сходимости алгоритма достаточно существования детерминированных стационарных стратегий, порождающих неразложимую марковскую цепь. Предельное поведение $Q$-функций игроков при больших значениях времени описано в терминах управляемых марковских процессов. Распределения действий игроков сходятся к распределениям Больцмана, зависящим от предельных $Q$-функций.
The Study of the Use of the Discursive Marker Para Empezar: Identification of its Values
Authors: Sanchis Cerdán María Pilar
Published: January 2019

In this work we intend to analyse, mainly from a pragmatic approach, real examples obtained from the Corpus del español in order to determine with scientific value the features which characterize in context the discourse marker para empezar. Our intention is to identify if there is a frequent use of this marker as a structurer of the elements in enunciation, or if it is, on the contrary, a marker used mostly as a modal particle that expresses the attitude of the speaker. If so, we also seek to recognize which are its specific uses.

Authors: Margot-Cattin Isabel , Kuhne Nicolas , Kottorp Anders , Cutchin Malcolm , Öhman Annika , Nygård Louise
Published: January 2019

OBJECTIVE. We describe the development of a questionnaire, Participation in Activities and Places Outside Home (ACT–OUT), for older adults with cognitive impairment and align it to people with mild- to moderate-stage dementia.

METHOD. ACT–OUT was developed in a cross-cultural collaboration in combination with three rounds of cognitive interviews in Switzerland with 26 older adults without cognitive impairment and five older adults with dementia. Qualitative data from the interviews were analyzed using a constant comparison approach.

RESULTS. The final ACT–OUT Version 1.0 consists of three parts: (1) questions targeting places older adults visit; (2) questions on aspects influencing participation, such as transportation, familiarity, and risk perception; and (3) questions on perception of self.

CONCLUSION. The development of an instrument such as ACT–OUT is more a cyclical than a linear process. This study is a first step toward a more systematic evaluation of out-of-home participation among older adults with and without dementia.

Authors: Moeinpour Leila , Nasiri Mahdi , Jodairi Pineh Aiyoub , Davarpanah Nikoo
Published: January 2019

Dynamic assessment is an approach primarily based on sociocultural theory of mind with the objective of combining instruction and assessment. In this approach learners’ development is simultaneously assessed regarding their Zone of Proximal Development. The present study was intended to investigate the effect of Mobile-Assisted Dynamic Assessment (MADA) on IELTS writing task one and also the EFL learners' perception to such approaches toward language learning. In order to achieve the aim of this quasi-experimental study, a social networking application, namely Telegram was applied on mobile phones. Based on the scores on the Oxford Quick Placement Test, twenty-three Iranian advanced-level EFL learners out of a population of 40 students participated in this study. An intact group went through a pre-test- treatment-post-test process. In the end, the participants were interviewed for their perceptions on mobile assisted dynamic assessment which was used to assess their writing skill. The results of the data analysis revealed that the participants experienced improvement in their writing after the treatment and obtained a significant increase in their scores of the post-test, and they benefited from the process of dynamic assessment through online mobile-learning environment. They further had a positive perception towards MADA.

There is a great interest on the strategical plan in Egypt for the cultivation of a new crop used as source of natural sweeteners Stevia rebaudiana (Spanti) and (China-1) var. Stem nodal segments containing axillary buds were used as an explant and inoculated on Murashige and Skoog’s (MS) medium containing 3% (w/v) sucrose, 0.8% (w/v) agar supplemented with various concentrations of flurprimidol (flur.), paclobutrazol (PBZ) and thidiazuron (TDZ). In Spanti var. maximum number of branches (6.52) and (6.4) were obtained in MS medium supplemented with 0.12 mg/l flur. and 0.2 mg/l TDZ, respectively with an average of 56.4 and 36.67 leaves per plantlet, having an average shoot length of 6.40 and 6.52 cm, respectively. The best in vitro root induction (100%) was achieved on MS medium with 0.16 mg/l flur. with an average of 10.00 roots per plantlet and root length of 4.82 cm (Spanti var.). Furthermore, in China-1 var. (MS) medium supplemented with 0.16mg/l flur. induced the best morphological characteristics. The rooted plantlets from explant planted on (MS) medium supplemented with 0.16 mg/l flur. were successfully established in soil and grown to maturity at the survival rate of 100% in the greenhouse in (Spanti) and (China-1) var. As a result of anatomy, all studied growth regulators significantly enhanced the anatomical characters of stevia varieties leaf and stem.flur.at 0.16 mg\l surpassed, for instance, midvein and lamina thickness, length and width of leaf vascular bundle as well as stem diameter, xylem and phloem thickness. Our data revealed that the numbers of protein bands in most of treatments are bigger than which in the control.
Virtual Sales Versus Classical Sales: A Perspective From Brazilian Airlines Customers
Authors: Silva Eduardo Silva da , Bridi Guilherme
Published: January 2019

The present paper aims to contribute to the debate about the use of digital marketing and relationship marketing tools for travel sales, and their respective reflexes in the customers preferences by virtual or classical sales channels of airlines tickets in Brazil. Therefore, it was applied a survey with 80 regular customers from domestic flights. It was identified that most of the respondents tend to buy their tickets into virtual sales channels, mainly in those that are better organized and offer the best rates. For those who chose for traditional channels tend to buy tickets from the airlines that focus on keeping a good service throughout the sales process, and also analyzing factors such as quality of service and safety. It was also concluded that it is extremely important to invest in digital marketing and relationships tools, once passengers are each more looking for a fair price combined with good quality.
Feature Models Preconfiguration Based on User Profiling
Authors: Dehmouch Ikram , Asri Bouchra El , Rhanoui Maryem , Maallam Mina El
Published: January 2019

Feature modeling is used to express commonality and variability among a family of software products called the software product line. To offer customized products to their customers, organizations need to build packages of features taking into consideration customer needs and preferences. This paper presents a platform named SPLP (Software Product Line Profiling) which allows pre-configuring feature models through the restriction of the configuration space to meet the requirements of a specific market segment. Considering that concerns and preferences of this latter are a key criteria to achieve a tailored pre-configuration, authors propose the integration of user profiling in the SPLP platform through the definition of a user profile model describing information about the user and the products he is used to consume. This information is then exploited by the SPLP platform to perform an automated pre-configuration according to each user profile requirements and preferences.
A Maturity Model for Assessing IS Risk Management Activity Considering the Dependencies Between Its Elements
Authors: Elmaallam Mina , Bensaid Hicham , Kriouile Abdelaziz
Published: January 2019

The information systems (IS) are a key asset for organizations. Therefore, managing IS risks becomes more and more important especially within a world in perpetual change. Since IS risk management creates added-value, it must follow a process of continuous improvement orchestrated by a maturity model that figures out available pathways for a better improvement. The studied literature shows the lack of an IS risk management maturity model that considers all IS components and specificities of risk management activity. The present article shows first this lack in the section related to the comparative analysis of the existing models. Then, it proposes a maturity model to address this issue. The proposed model aims to assess the information system risk management activity while considering the dependencies between its elements.
The Relationship Between Perceived Human Resource Management Practices and Turnover-Intention: The Mediating Role of Organizational Attractiveness
Authors: Obeidat Ahmad M.
Published: January 2019

This study examines whether employees’ attraction to the organisation mediates the relationship between their perceptions of human resource management (HRM) practices (as a bundle) and their turnover intentions. Hypotheses were developed based on the propositions of social exchange theory, findings of previous research and theory of reasoned action. Survey data were collected from 297 individuals who work in organisations operating in the Hashemite Kingdom of Jordan. Subsequently, the proposed relations were tested. It was found that: 1) perceived HRM practices is negatively and significantly related to turnover-intention; 2) perceived HRM practices is positively and significantly related to organisational attractiveness; and 3) organisational attractiveness is negatively and significantly related to turnover intention and partially mediates the negative relationship between perceived HRM practices and turnover intention. The implications of these findings for line managers and HR practitioners are also discussed in addition to future research directions.

The paper shall try to make some unique contribution towards understanding the role that social media plays in transforming Arab youth identity, and its socio-political impact.
Impact of Coordinated Capacity Mechanisms on the European Power Market
Authors: Bucksteeg Michael , Spiecker Stephan , Weber Christoph
Published: January 2019

There is an ongoing debate on the introduction of capacity markets in most European countries while a few of them have already established capacity markets. Since the implementation of independent national capacity markets is not in line with the target of a pan-European internal electricity market we investigate the impacts of uncoordinated capacity markets compared with coordinated capacity markets. A probabilistic approach for the determination of capacity requirements is proposed and a European electricity market model (E2M2s) is applied for evaluation. The model simultaneously optimizes investments and dispatch of power plants. Besides the impact on generation investments, market prices and system costs we analyze effects on production and security of supply. While coordinated capacity markets reveal high potentials for cross-border synergies and cost savings, uncoordinated and unilateral implementations can lead to inefficiencies, in particular free riding effects and endanger security of supply due to adverse allocation of generation capacity.
The Chinese in Southern Europe: Has urban regeneration addressed their new form of clustering?
Authors: Verdini Giulio , Russo Enrico
Published: January 2019

This paper attempts to analyse the particular features of Chinese clustering in two southern European cities and the urban regeneration responses employed in the decade 2005-2015: Prato in Italy and Santa Coloma de Gramenet in Spain, which are among the cities with the highest rate of Chinese in-migration within their respective countries. The main aim is to show which urban regeneration policies have been adopted in both contexts and to evaluate, in comparative terms, how they have addressed the two local Chinese communities. The paper will argue that their form of clustering, developed since the 1990s, has featured a certain degree of social segregation and tensions with local communities. On the other hand, they have become two dynamic urban nodes in supra-local business networks, possibly demanding new forms of engagement in the governance system. The results show that the urban regeneration policies in place have partially failed to acknowledge the changing nature of their form of clustering, with the risk to exacerbate existing conflicts and to prevent beneficial mutual collaborations.

NOVA GAZETA RENANA: A POLÍTICA EM SUA DIMENSÃO NEGATIVA NO PENSAMENTO DE MARX
Authors: Nobre Lopes Fátima Maria , Silva Filho Adauto Lopes da
Published: January 2019

Este texto em si não discorre sobre a concepção da política em Marx. Trata-se apenas de uma sumária exposição dos seus artigos A Burguesia e a Contra Revolução, datados de 10 a 31 de dezembro de 1848, que fizeram parte dos seus escritos no jornal Nova Gazeta Renana.  Dada à riqueza de conteúdos dos supracitados artigos, dentre eles selecionamos a concepção negativa da política, tentando resgatar os lineamentos que identificam tal concepção. Desta forma, dividimos esta exposição em três partes: a primeira parte introduz a posição política de Marx no referido jornal; a segunda parte trata dos artigos propriamente ditos, na qual procuramos apresentá-los citando trechos principais que indicam o assunto tratado cujo fundamento se encontra nas considerações da terceira parte com destaque à crítica de Marx ao pensamento político de Hegel.
MARXISMO OCIDENTAL: CAUSALIDADE E HISTÓRIA EM MERLEAU-PONTY
Authors: Benevides Rodrigo Barbosa Gomes
Published: January 2019

Em As Aventuras da Dialética (1955) Merleau-Ponty cunhou o termo “Marxismo Ocidental” para designar certa perspectiva do materialismo histórico que afastava-se de leituras dogmáticas provenientes, principalmente, do partido soviético. Dessa forma, o artigo pretende, em primeiro lugar, revisitar a defesa que Merleau-Ponty faz da noção de práxis na década de 1940 ao apontá-la como conceito fundamental na articulação entre lógica e contingência na filosofia da história marxista. Em seguida, veremos como a aproximação inicial de Merleau-Ponty ao marxismo, na qual considerava-se o materialismo histórico como esquema teórico fundamental para desvelar a cadeia causal da história, ganha novos contornos durante os anos de 1950, quando uma reavaliação de suas posições (a partir do estruturalismo de Saussure) acaba por indicar o marxismo não como a única lente interpretativa da história, mas sim como uma perspectiva dentre outras, por mais privilegiada que seja. Dito isso, o artigo pretende, em sua conclusão, esboçar uma crítica a tal mudança de pensamento em Merleau-Ponty ao defendermos o materialismo histórico como a melhor teoria disponível para o desvelamento da causalidade histórica.
JUSTIÇA E ÉTICA COMO FUNDAMENTOS DO DIREITO NA FILOSOFIA ANTIGA
Authors: Pereira Filho Gerson , Bernardo Isadora Prévide
Published: January 2019

O artigo propõe uma apresentação dos conceitos de Justiça e Ética a partir da filosofia de Sócrates e Platão, no contexto grego, assim como nos remete ao pensamento e obra de Cícero, no contexto romano, para nos permitir pensar as bases da filosofia do direito. Ao se considerar a relação entre o jusnaturalismo e a filosofia da natureza entre os gregos antigos, e a passagem para a antropologia socrático-platônica, posteriormente consolidada em seus aspectos jurídicos por Cícero e sua base estóica, se pretende pensar a questão das constituições legislativas, formas de governo, princípios e fins das leis na perspectiva humanista que tais pensadores clássicos sugeriram, na contramão do tecnicismo jurídico contemporâneo. Em Sócrates como uma “filosofia do agir”, em Platão como uma possibilidade efetiva para o ordenamento da pólis, em Cícero como princípio para a vida pública, encontramos fundamentações que muito podem oferecer para a filosofia do direito na atualidade.
A SUPERAÇÃO DA CONDIÇÃO DE SUBJUGAÇÃO DAS MULHERES E SEU SIGNIFICADO PARA A HISTÓRIA HUMANA (O PENSAMENTO DE SIMONE DE BEAUVOIR EM DIÁLOGO COM O MATERIALISMO HISTÓRICO DIALÉTICO)
Authors: Felden Patrícia , Coelho Paulo Vinícius Nascimento
Published: January 2019

RESUMODesenvolvendo uma análise crítica sobre a condição da mulher na história (condição que por muito tempo se caracterizou, e ainda parece se manter, pela subjugação), a filósofa francesa Simone de Beauvoir dialoga com importantes correntes de pensamento como a fenomenologia, existencialismo e, em especial, o Materialismo Histórico Dialético, o qual destacaremos no presente trabalho, sublinhando as aproximações entre o pensamento de Beauvoir e o projeto social revolucionário do Socialismo Científico que parte da teoria materialista de Marx e Engels, destacando as noções de “alteridade e reciprocidade” e a intenção ética de superação da condição de subjugação das mulheres diante dos homens (superação a qual, em uma sociedade igualitária e livre, se supõe que pudesse ser realizada)

It has been 20 years since we have organized the first edition of IHC in 1998. So much has changed regarding not only technology, but also how it is inserted in our society. During this time, technology and people´s interaction with it have become ubiquitous and part of our everyday lives mediating many (if not most) of our ordinary activities from communicating with other people, to work, entertainment and Government services. As professionals who generate technology, this change has also raised our awareness, concern and attitude towards the social responsibility and ethics involved with developing technology and its use by society. In this panel, we discuss how social responsibility and ethics have changed and what is our role, as professionals, going forward.

Published: January 2019

Este artigo relata a experiência da realização de uma disciplina sobre acessibilidade e inclusão digital em conjunto com um projeto de extensão, para promover a ação entre estudantes e comunidades externas na produção de materiais educacionais abertos e acessíveis. A disciplina foi ofertada no primeiro semestre de 2018 a estudantes dos cursos de Bacharelado em Sistemas de Informação (BSI) e Engenharia da Computação (EC) da Universidade Tecnológica Federal do Paraná (UTFPR). A combinação entre disciplina e projeto de extensão teve como objetivo apresentar aos estudantes fundamentação teórica e desafios práticos, e incluiu o envolvimento das comunidades na definição e produção de materiais relacionados às necessidades dessas pessoas. Deste modo, a disciplina resultou no desenvolvimento de Recursos Educacionais Abertos (REAs) com temas de demanda dos membros das comunidades. Os REAs foram utilizados em cursos-piloto, ofertados pelos(as) estudantes para membros das comunidades externas envolvidas nas decisões do projeto. As ações resultantes da união entre disciplina e projeto de extensão podem ser utilizadas como estudo de caso para pessoas que desejam realizar atividades semelhantes às desempenhadas pelas pessoas que escreveram este artigo, e que são discutidas neste trabalho.

Published: January 2019

IHC's interdisciplinarity teaching solutions generally focus on supporting teachers to plan classes and organise didactic content. Given this context, some studies show that in the algorithms ' disciplines of a computational course there is a logical complexity that requires more attention. In this perspective, we perceive the need to support those involved to implant the interdisciplinarity of IHC in a course that had algorithm discipline. Thus, this article defines and describes a strategy that describes the key elements and activities for such deployment and evaluation. To do so, a case study was carried out to analyze the difficulties in a course for the students of the algorithm discipline to analyze and correct an example with usability error, verified through a heuristic inspection.

O objetivo do presente estudo é verificar se existem diferenças significativas nos indicadores econômico-financeiros de empresas que atuam em segmentos específicos do Setor de Transporte brasileiro. Os procedimentos metodológicos caracterizam a pesquisa como descritiva e documental, com abordagem quantitativa das informações. A amostra é formada por nove empresas, distribuídas nos segmentos de transporte aéreo, ferroviário, hidroviário e rodoviário. O período de análise compreendeu os anos de 2010 a 2016. Para a análise dos dados utilizou-se a estatística descritiva, teste de diferença de médias Kruskal-Walls, com o auxílio do software SPSS®, versão 20.0. Os resultados revelaram que o desempenho econômico-financeiro das empresas que compõem os segmentos de transporte é diferente quanto aos indicadores de curto prazo, como endividamento, capacidade de pagamento e retorno do investimento. Foi observado ainda, que essas empresas apresentam dependência de capital de terceiros de longo prazo para financiar os seus ativos fixos, o que se torna justificado pelo elevado volume de investimentos que o segmento requer.

Published: January 2019

O objetivo deste trabalho foi verificar a relação entre o nível de evidenciação das subvenções governamentais e as características das companhias de capital aberto brasileiras. Para tanto, foi elaborada uma lista de verificação, com base no pronunciamento técnico CPC 07 (R1), abordando os requisitos estabelecidos pelo referido pronunciamento, quanto à correta evidenciação das subvenções governamentais nos demonstrativos contábeis e notas explicativas. Por meio da lista de verificação foi possível medir o nível de evidenciação das companhias analisadas e, relacionar com as principais características das companhias, como: i) empresa de auditoria, ii) resultado do exercício social e iii) classificação de subsetor. Além disso, elaborou-se um ranking com os maiores e menores níveis de evidenciação apurados na amostra. Os documentos analisados foram: Demonstração do Resultado do Exercício (DRE), Balanço Patrimonial (BP) e as notas explicativas referentes ao ano de 2016 de 260 companhias que apresentaram algum tipo de subvenção governamental em seus demonstrativos contábeis. Os resultados da pesquisa demonstraram que as companhias brasileiras analisadas, em sua maioria, possuem um baixo nível de evidenciação das subvenções governamentais, em que apenas 26 companhias da amostra obtiveram um nível de evidenciação igual ou superior a 50%. Concluiu-se, também, que os resultados da pesquisa não sugerem tendência de relação entre as características analisadas (empresa de auditoria, resultado do exercício e subsetor) com o baixo nível de evidenciação das companhias.
Grue-Sørensen og psykologien
Authors: Vejleskov Hans
Published: January 2019

As a primary school teacher in Copenhagen, and, simultaneously, as a student of philosophy at The Universityof Copenhagen, Grue-Sörensen became so well acquainted with contemporary psychology that he, in theyears 1941-55, worked as a school psychologist in Copenhagen. Furthermore, from 1934 until 1955, he published 22 articles or chapters about psychological issues. The present contribution presents and characterizes the 22 publications categorized in (1) works about developmental psychology (including very early mentioning of Jean Piaget and Heinz Werner in Danish), and (2) works about central psychological issues – motivation, learning, and cognition. In the last Section, Grue-Sörensen’s understanding of the relationships between the fields of education, philosophy and psychology is discussed, especially the question of the importance of psychology to education. Finally, it is concluded that, according to Grue-Sörensen, the value of (educational) philosophy to psychology is not to off er insight into theories of science but, rather, inspiration to use words and concepts in a clear and careful way.

Published: January 2019

Background

Pseudomonas aeruginosais ubiquitous, has intrinsic antibiotic resistance mechanisms, and is associated with serious hospital-associated infections. It has evolved from being a burn wound infection into a major nosocomial threat. In this study, we compared and correlated the antimicrobial resistance, virulence traits and clonal relatedness between clinical and fresh water environmental isolates ofP. aeruginosa.

Methods

219P. aeruginosaisolates were studied: (a) 105 clinical isolates from 1977 to 1985 (n = 52) and 2015 (n = 53), and (b) 114 environmental isolates from different fresh water sources. All isolates were subjected to ERIC-PCR typing, antimicrobial susceptibility testing and virulence factor genes screening.

Results

Clinical and environmental isolates ofP. aeruginosawere genetically heterogenous, with only four clinical isolates showing 100% identical ERIC-PCR patterns to seven environmental isolates. Most of the clinical and environmental isolates were sensitive to almost all of the antipseudomonal drugs, except for ticarcillin/clavulanic acid. Increased resistant isolates was seen in 2015 compared to that of the archived isolates; four MDR strains were detected and all were retrieved in 2015. All clinical isolates retrieved from 1977 to 1985 were susceptible to ceftazidime and ciprofloxacin; but in comparison, the clinical isolates recovered in 2015 exhibited 9.4% resistance to ceftazidime and 5.7% to ciprofloxacin; a rise in resistance to imipenem (3.8% to 7.5%), piperacillin (9.6% to 11.3%) and amikacin (1.9% to 5.7%) and a slight drop in resistance rates to piperacillin/tazobactam (7.7% to 7.5%), ticarcillin/clavulanic acid (19.2% to 18.9%), meropenem (15.4% to 7.5%), doripenem (11.5% to 7.5%), gentamicin (7.7% to 7.5%) and netilmicin (7.7% to 7.5%). Environmental isolates were resistant to piperacillin/tazobactam (1.8%), ciprofloxacin (1.8%), piperacillin (4.4%) and carbapenems (doripenem 11.4%, meropenem 8.8% and imipenem 2.6%). Both clinical and environmental isolates showed high prevalence of virulence factor genes, but none were detected in 10 (9.5%) clinical and 18 (15.8%) environmental isolates. TheexoTgene was not detected in any of the clinical isolates. Resistance to carbapenems (meropenem, doripenem and imipenem), β-lactamase inhibitors (ticarcillin/clavulanic acid and piperacillin/tazobactam), piperacillin, ceftazidime and ciprofloxacin was observed in some of the isolates without virulence factor genes. Five virulence-negative isolates were susceptible to all of the antimicrobials. Only one MDR strain harbored none of the virulence factor genes.

Conclusion

Over a period of 30 years, a rise in antipseudomonal drug resistance particularly to ceftazidime and ciprofloxacin was observed in two hospitals in Malaysia. The occurrence of resistant environmental isolates from densely populated areas is relevant and gives rise to collective anxiety to the community at large.

Published: January 2019

A cobalt‐catalyzed direct C−H/N−H functionalization of benzoyl hydrazide with isocyanide by utilizing 2‐(1‐methylhydrazinyl)pyridine (MHP) as a bidentate directing group has been developed. This formal [4+1] cycloaddition protocol showed high efficiency and remarkable functional group tolerance, and the ubiquitous 3‐iminoisoindolinones were obtained in good to excellent yields in the presence of the earth‐abundant cobalt catalyst. Moreover, this transformation was accomplished by employing environmentally friendly oxygen as the sole oxidant in the absence of any other additives.

Lichtgetriebene Ein‐Elektronen‐Transferprozesse als Funktionsprinzip in der Schwefel‐ und Selen‐Multikatalyse
Authors: Breder Alexander , Depken Christian
Published: January 2019

Das Prinzip der Kooperativität stellt inzwischen einen Grundpfeiler im Bereich der Multikatalyse dar. Durch die Kombination zweier oder mehrerer Katalysatoren mit mechanistisch unterschiedlichen Aktivierungsmodi, die gemeinsam chemische Prozesse vorantreiben, werden zuweilen Bindungsknüpfungen ermöglicht, zu denen keiner der beteiligten Katalysatoren einzeln imstande wäre. Ein stetig wachsender Teilbereich der Multikatalyse befasst sich mit lichtgetriebenen Ein‐Elektronen‐Transferprozessen, die durch die synergistische Verzahnung von Schwefel‐ oder Selenkatalysatoren mit Photoredoxkatalysatoren aufrechterhalten werden. Reaktionen, die auf diesem Funktionsprinzip beruhen, bergen ein enormes synthetisches Potential, da sie rasche und hoch ökonomische Zugangswege zu komplexen molekularen Strukturen ermöglichen können. Vor diesem Hintergrund ist das Ziel dieses Aufsatzes, jüngste methodische Entwicklungen auf diesem Gebiet näher zu beleuchten und anhand ausgewählter Beispielreaktionen einen allgemeinen Einblick in ihre mechanistischen Grundlagen zu vermitteln.

This study investigated the role of flaxseed meal (FSM), a rich terrestrial source of ω‐3 fatty acids, in the alteration of the fatty acid profile and metabolism, health indices, physicochemical properties, and sensory quality of broiler chicken meat. The broiler chickens were fed 100 g FSM kg−1 diet for different time periods (1, 2, 3, 4, and 5 weeks). The results revealed that 100 g FSM feeding in broiler chickens for at least 3 weeks increased (P < 0.01) the EPA, DHA, MUFA, PUFA, ω‐3 PUFA, and ω‐6 PUFA of broiler chicken meat with the corresponding decrease in palmitic acid, stearic acid, and SFA content. 100 g FSM feeding up to 3 weeks has increased the Δ9‐desaturases (P < 0.05), thioesterase index (P < 0.01), and Δ5‐desaturase + Δ6‐desaturase activity (P < 0.01) along with an improvement in health indices (P < 0.01) of chicken meat. Similarly, a reduction in meat cholesterol and fat content of thigh meat (P < 0.01) was observed by feeding 100 g FSM for at least 3 weeks with no effect on the pH, color scores, and sensory evaluation of broiler chicken meat. The water‐holding capacity (WHC) and extract release volume (ERV) decreased, whereas, drip loss of meat increased (P < 0.01) due to the feeding of 100 g FSM beyond 3 weeks. Thus, this study concluded that 100 g FSM feeding for 3 weeks in broiler chickens significantly improves the fatty acid profile, lipid metabolism, and health indices of meat, without compromising the physicochemical properties of broiler chicken meat.
Covalorization of Palm Oil‐Refining by‐Products as Soaps
Authors: Punvichai Teerasak , Pioch Daniel
Published: January 2019

This study deals with the covalorization of spent bleaching clay (SBC) and palm fatty acid distillate (PFAD), the by‐products of palm oil‐refining plants (3 Mt. year−1), through soap manufacture. Obtained SBC and PFAD samples show differing acidity and saponification values depending on their content of free fatty acids and of acylglycerols. The SBC sample had an acidity of 60.5% and a saponification value of 182 mg KOH g−1 of oil, and the PFAD sample has an acidity of 88.4% and a saponification value of 204 mg KOH g−1 of oil. Soaps are prepared using the stoichiometric amount of NaOH, under varying proportion of water introduced through the basic solution. The overall reaction (neutralization and saponification) is complete (99.9%) with PFAD, whereas the yield reaches only 56.1% with SBC. When mixing SBC and PFAD, for example under a 1:1 weight ratio, the overall reaction completion (87.7%) is surprisingly higher than expected based on the computed individual reaction yields (78%), showing a synergistic effect of about 10% on the course of the saponification reaction of acylglycerols in SBC. The water content was found to be a critical parameter, 30% w/w of added water providing the highest yield. These results show an innovative way for covalorizing two important by‐products of palm oil industrial processing as a single final product. By‐products of the physical refining of other oils could also be valorized following the same method.

Precipitation samples were collected in the Jeju Island during 2015–2016, and the ionic components of the precipitation were analyzed to investigate the chemical composition and pollution characteristics of the precipitation. In a comparison of ion balance, electrical conductivity, and acid fraction for verification of the analytical data, the correlation coefficients showed within the range of 0.953–0.991. During the study period, the volume‐weighted mean pH and electrical conductivity were 5.1 and 15.9 μS/cm, respectively. The precipitation was weakly acidic, with a high frequency of precipitation (43.8%) in the range of pH 5.0–5.5. The ionic strength of the precipitation was 0.2 ± 0.2 mM, indicating that 44.5% of the total precipitation was within the pure precipitation criteria. The volume‐weighted mean concentrations (μeq/L) of the ionic components in the precipitation were in order of Cl− > Na+ > NH4+ > nss‐SO42− > NO3− > Mg2+ > nss‐Ca2+ > H+ > K+ > HCOO– > CH3COO– > HCO3– > F− > NO2− > CH3SO3− > PO43−. Sea salt (Cl−, Na+, Mg2+) and secondary pollutants (NH4+, nss‐SO42−, NO3−) contributed to the total ionic species in the precipitation samples by 52.6% and 33.6%, respectively. The acidity contributions by inorganic (nss‐SO42−, NO3−) and organic (HCOO−, CH3COO−) acids were 89.3% and 10.7%, respectively. The neutralization factors by ammonium and calcium carbonate were 0.44 and 0.21, respectively. A clustered back trajectory analysis showed that the concentrations of secondary pollutants were relatively high when airflow moved to Jeju Island from the China continent.

Solid solutions with of Cu3VS4 with either Cu3NbS4 or Cu3TaS4 (Cu3Nb1−xVxS4 or Cu3Ta1−xVxS4) were prepared by a solid‐state reaction and adopted a sulvanite structure. Their band gaps were 1.6–1.7 eV corresponding to the absorption of a wide range of visible light. Ru cocatalyst‐loaded Cu3MS4 (M=V, Nb, Ta), Cu3Nb1−xVxS4, and Cu3Ta1−xVxS4 showed photocatalytic activities for sacrificial H2 evolution under visible‐light irradiation. Most solid solutions showed better activities than the single‐component Cu3MS4 (M=V, Nb, Ta). Cu3MS4 (M=V, Nb), Cu3Nb1−xVxS4, and Cu3Ta1−xVxS4 also functioned as photoelectrodes and gave cathodic photocurrents under visible‐light irradiation, indicating a p‐type semiconductor character. Cu3Nb0.9V0.1S4 showed the best photocatalytic and photoelectrochemical performances. When Ru‐loaded Cu3Nb0.9V0.1S4 was used as a photocathode with a CoOx‐loaded BiVO4 photoanode, photoelectrochemical water splitting proceeded under simulated sunlight irradiation without an external bias.
Intermingling of chromosome territories

Published: January 2019

The importance of higher order nuclear structure and compartmentalization for the control of the cell life is now indisputable. The genome of higher eukaryotes is organized into definite chromosome territories, and the three‐dimensional organization of these territories may be intently related to genomic function, global regulation of gene expression, and even formation of exchange aberrations. In this review, we discuss our current understanding of the chromosome territories phenomenon and briefly describe how genes relocation in three‐dimensional arrangement of the genome may influence their functioning. We explain how the intermingling of the edges of chromosome territories allows the formation of rare long‐range interchromosomal interactions. Moreover, we illustrate recent discoveries describing the mechanisms of physical proximity‐based chromosome translocations and its clinical consequence for fusion genes formation and tumor development. Finally, we characterize the inner structure of the intermingled chromosomes briefly, and explain how chromosome intermingling affects gene expression regulation.
