A Highly Crystalline Anthracene-Based MOF-74 Series Featuring Electrical Conductivity and Luminescence
Authors: Scheurle Patricia , Mähringer Andre , Jakowetz Andreas , Hosseini Pouya , Richter Alexander , Wittstock Gunther , Medina Dana D. , Bein Thomas
Published: June 2019

Recently, a small group of metal-organic frameworks (MOFs) has been discovered featuring substantial charge transport properties and electrical conductivity, hence promising to broaden the scope of potential MOF applications in fields such as batteries, fuel cells and supercapacitors. In combination with light emission, electroactive MOFs are intriguing candidates for chemical sensing and optoelectronic applications. Here, we incorporated anthracene-based building blocks into the MOF-74 topology with five different divalent metal ions, that is, Zn2+, Mg2+, Ni2+, Co2+ and Mn2+, resulting in a series of highly crystalline MOFs, coined ANMOF-74(M). This series of MOFs features substantial photoluminescence, with ANMOF-74(Zn) emitting across the whole visible spectrum. The materials moreover combine this photoluminescence with high surface areas and electrical conductivity. Compared to the original MOF-74 materials constructed from 2,5-dihydroxy terephthalic acid and the same metal ions Zn2+, Mg2+, Ni2+, Co2+ and Mn2+, we observed a conductivity enhancement of up to six orders of magnitude. Our results point towards the importance of building block design and the careful choice of the embedded MOF topology for obtaining materials with desired properties such as photoluminescence and electrical conductivity.
Interfacial Choline-Aromatic Cation-Pi Interactions Can Contribute as Much to Peripheral Protein Affinity for Membranes as Aromatics Inserted Below the Phosphates
Authors: Waheed Qaiser , Khan Hanif M. , He Tao , Roberts Mary , Gershenson Anne , Reuter Nathalie
Published: June 2019

Membrane binding interfaces of peripheral proteins are restricted to a small part of their exposed surface so the ability to engage in strong selective interactions with membrane lipids at various depths in the interface, both below and above the phosphates, is an advantage. Driven by their hydrophobicity aromatic amino acids preferentially partition into membrane interfaces often below the phosphates. Yet enthalpically favorable interactions with the lipid headgroups, above the phosphate plane, are likely to further stabilize high interfacial positions. Using Free Energy Perturbation we calculate the energetic cost of alanine substitution for 11 interfacial aromatic amino acids from 3 peripheral proteins. We show that involvement in cation-π interactions with the headgroups (i) increases the ΔΔGtransfer as compared to insertion at the same depth without cation-π stabilization and (ii) can contribute at least as much as deeper insertion below the phosphates, highlighting the multiple roles of aromatics in peripheral membrane protein affinity.
Chemical Synthesis of (+)-Brevianamide a Supports a Diels–Alderase-Free Biosynthesis
Authors: Godfrey Robert , Green Nicholas , Nichol Gary , Lawrence Andrew
Published: June 2019

The fungal-derived bicyclo[2.2.2]diazaoctane alkaloids are of significant interest to the scientific community for their potent and varied biological activities. Within this large and diverse family of natural products the insecticidal metabolite (+)-brevianamide A is particularly noteworthy for its synthetic intractability and inexplicable biogenesis. Despite five decades of research, this alkaloid has never succumbed to chemical synthesis. It has been suggested that a proposed Diels–Alder reaction in the biosynthesis of (+)-brevianamide A requires a Diels–Alderase enzyme. We herein report the first chemical synthesis of (+)-brevianamide A (7 steps, 8.0% overall yield, 750 mg scale), which provides compelling evidence in support of a Diels–Alderase-free biosynthesis; a significant departure from the established biosynthesis of related alkaloids.
Named Entity Recognition and Normalization Applied to Large-Scale Information Extraction from the Materials Science Literature
Authors: Weston Leigh , Tshitoyan Vahe , Dagdelen John , Kononova Olga , Persson Kristin , Ceder Gerbrand , Jain Anubhav
Published: June 2019

Over the past decades, the number of published materials science articles has increased manyfold. Now, a major bottleneck in the materials discovery pipeline arises in connecting new results with the previously established literature. A potential solution to this problem is to map the unstructured raw-text of published articles onto a structured database entry that allows for programmatic querying. To this end, we apply text-mining with named entity recognition (NER), along with entity normalization, for large-scale information extraction from the published materials science literature. The NER is based on supervised machine learning with a recurrent neural network architecture, and the model is trained to extract summary-level information from materials science documents, including: inorganic material mentions, sample descriptors, phase labels, material properties and applications, as well as any synthesis and characterization methods used. Our classifer, with an overall accuracy (f1) of 87% on a test set, is applied to information extraction from 3.27 million materials science abstracts - the most information-dense section of published articles.Overall, we extract more than 80 million materials-science-related named entities, and the content of each abstract is represented as a database entry in a structured format. Our database shows far greater recall in document retrieval when compared to traditional text-based searches due to an entity normalization procedure that recognizes synonyms. We demonstrate that simple database queries can be used to answer complex \meta-questions" of the published literature that would have previously required laborious, manual literature searches to answer. All of our data has been made freely available for bulk download; we have also made a public facing application programming interface (https://github.com/materialsintelligence/matscholar) and website http://matscholar.herokuapp.com/search for easy interfacing with the data, trained models and functionality described in this paper. These results will allow researchers to access targeted information on a scale and with a speed that has not been previously available, and can be expected to accelerate the pace of future materials science discovery.
PARTICIPAÇÃO SOCIOPOLÍTICA DOS PROFISSIONAIS DE ENFERMAGEM DE UM HOSPITAL FILANTRÓPICO DE VITÓRIA/ES
Authors: Polezi Pereira Maryellen , Feitosa Dibai de Castro Caroline , Fiorin Bruno Henrique
Published: June 2019

Objetivou-se descrever os aspectos relacionados à participação sociopolítica da equipe de enfermeiros e técnicos de enfermagem. Trata-se de pesquisa descritiva, com delineamento transversal, realizada no Hospital Santa Casa de Misericórdia de Vitória/ES. Incluíram-se os enfermeiros e técnicos de enfermagem e excluíram-se enfermeiros e técnicos de enfermagem que estavam de licença médica no período de coleta de dados. A análise dos dados foi feita por meio do programa estatístico SPSS 17. Participaram do estudo 282 profissionais de enfermagem, com prevalência do sexo feminino (82,3%). Os cargos de nível médio responderam por 75,5% dos participantes, sendo seguidos pela categoria de enfermeiros assistenciais, com 24,5%. Em relação a lutas de classe, percebe-se maior interesse dos enfermeiros, com prevalência da classe masculina, mesmo sendo eles a minoria na equipe. Ainda existem profissionais que não conhecem nem participam de nenhuma entidade de representação, mesmo sabendo que a associação ao Conselho Regional de Enfermagem (COREN) é obrigatória para o exercício da enfermagem. A organização política da enfermagem brasileira é caracterizada por avanços e retrocessos. Embora exista um número expressivo de profissionais interessados na política, é necessário maior envolvimento da categoria.

Refazer o corpo e libertar-se do espetáculo: sugestões de Gordon Craig e Étienne Decroux para composições em Des-atos
Authors: Braga - Universidade Federal de Minas Gerais Bya
Published: June 2019

O presente ensaio apresenta propostas artísticas de Gordon Craig e Étienne Decroux buscando discutir procedimentos de composição e decomposição performativas por meio delas. Esta reflexão encontra apoio inicial nas noções do Teatro de Movimento e também da artesania de ator manifestada por meio da Mímica Corporal Dramática. Busca-se reconhecer que a constituição de um espetáculo não precisa ser a motivação preferencial de um ato cênico e que a performatividade, neste caso, valoriza o exercício do ator/performer sobre si mesmo, seu corpo, podendo sinalizar uma conduta de questionamento da própria produção artística, vindo a ser um “des-ato” (Kaprow, 2007).
Rasgos e véus
Authors: Washington - Universidade de Brasília Claudia
Published: June 2019

O rasgo como ação em arte, as características do espaço onde opera e as decorrências dessa ação são os focos aqui propostos. A partir da prática artística e de referências dessa mesma natureza são estabelecidas interlocuções, contraposições e misturas com textos filosóficos e de arte, em especial com o livro Os cinco sentidos: Filosofia dos corpos misturados 1, de Michel Serres. Este último inspira o teor desta escrita, permeando-a do início ao fim. Nesse percurso é possível identificar oposições e complementaridades entre os regimes espaciais enredados e o rasgo

Arte indígena e arte brasileira
Authors: Corrêa Patricia
Published: June 2019

No campo rarefeito da historiografia artística no Brasil, cabe aos artefatos e práticas indígenas o lugar de capítulo inicial, como frutos de culturas sem história, obliterados pelo advento da arte brasileira. Nos capítulos subsequentes, o indígena restringe-se a tema figurativo, objeto da melancolia acadêmica ou do essencialismo modernista, e nunca se constitui como agente capaz de produzir materialidades, processos e sistemas artísticos determinantes para a arte nacional. Ressaltamos a exceção de Mário Pedrosa, que nos anos 1960 e em intenso contato com a produção contemporânea, propôs a compreensão de condições e processos artísticos locais a partir da arte indígena.

Rektion, Valenz, Intention – zu einigen Problemen der Abhängigkeitsrelation
Authors: Kozmová Ružena
Published: June 2019

Die Engelsche Grammatik der deutschen Sprache (1988, 2004) gehort zweifelsohne zu den Meilensteinen der Valenztheorie. Ihre Effektivitat, Brauchbarkeit, relative Einfachheit in der Formulierung der Regel fand insbesondere im DaF‑Bereich eine grose Anerkennung. In diesem Beitrag wird die Auffassung der Valenz im Engelschen Sinne mit der Valenz, bzw. mit der Intentionstheorie im Slowakischen konfrontiert. Die Entwicklung der Valenztheorie im deutschsprachigen Raum einerseits und die der Intentionstheorie auf dem slawischen andererseits, weist viele ahnliche aber auch unterschiedliche Zuge auf. Es wird sich zeigen, dass es sich um eine parallele Entwicklung des gleichen Sprachphanomens handelt.

Wahrend sich die Valenztheorie in der Germanistik schon seit den siebziger Jahren groser Beliebtheit erfreut, sodass praktisch alle seitdem erschienenen Grammatiken des Deutschen sich ihrer bedient haben, um die deutsche Syntax zu beschreiben, ist die Theorie in der Hispanistik lange Zeit einfach ignoriert worden. Untersucht wird in diesem Beitrag, wie sich die Rezeption der Theorie in der spanischen Grammatikschreibung entwickelt hat.
Das Valenzmodell und die Existenzialkonstruktionen. Eine Untersuchung zu den polnischen Entsprechungen der es gibt‑Sätze im Deutschen
Authors: Pilarski Anna
Published: June 2019

Im Artikel werden polnische Existenzialkonstruktionen untersucht, die den deutschen es gibt‑Sätzen entsprechen. In Betracht werden folgende Schwerpunkte gezogen: die syntaktische Funktion des Pronomens es in den existenzialen es gibt‑Sätzen, die syntaktische Bestimmung der NP in den polnischen Entsprechungen, die satzfinale Position der verfügbaren NP bei der existentialen Lesart in der Informationsstruktur sowie die Kongruenzmarkierungen in den Verneinungsformen der es gibt‑Entsprechungen im Polnischen. Es wird überlegt, welche Möglichkeiten für die Erklärung das DVG‑Modell anbietet und durch welche andere Vorschläge es ergänzt werden kann.
Zur Darstellung der Valenz von Phraseologismen in Online‑Wörterbüchern für das Sprachenpaar Deutsch und Polnisch
Authors: Janus Dominika
Published: June 2019

Das Ziel der Untersuchung ist festzustellen, welche Qualitat ausgewahlte deutsch‑polnische Online‑Worterbucher in Bezug auf die Darstellung der Valenz von Phraseologismen prasentieren. Um dies zu erreichen, werden die phraseographischen Nennformen einerseits auf ihre valenzbezogene Charakteristik hin, vor allem aber hinsichtlich der externen und qualitativen (semantischen) Valenz, uberpruft. Es soll in diesem Kontext auch der Frage nachgegangen werden, ob das Mehr der elektronischen Lexikographie, u.a. keine Platzgrunde beachten zu mussen, auf das Niveau der Valenzbeschreibung von Phraseologismen einen positiven Einfluss hat. Die Ergebnisse der Untersuchung geben die Antwort auf die Frage, in welchen Online‑Worterbuchern nachzuschlagen und von welchen Nachschlagewerken abzuraten ist.
Genus in „gerechter Sprache“
Authors: Sadziński Roman
Published: June 2019

Der Titel des Aufsatzes spielt auf die Bibel in gerechter Sprache (3. Aufl. 2007) an. Es wird dafür argumentiert, dass die neue, deklarierterweise im Zeichen der „Befreiungs‑ und der feministischen Theologie“ stehende Übersetzung wegen starker ideologischer Einbindung nicht sprachwissenschaftlich genug begründet sei. Die Forderung, die natürliche Genusmarkierung – vorzugsweise die feminine – habe als immanentes Merkmal einer Personenbezeichnung zu gelten, ignoriert die sprachwissenschaftliche Evidenz, dass das Genus (oft auch inflationär) auf verschiedenen Sprachebenen zugewiesen werden kann – nicht zuletzt durch rekurrente Personalpronomina auf der Satz‑ bzw. Textebene. Die exemplarisch gebrachten Belege aus der Bibel zeigen, dass die genannte Forderung ggf. für unnötige Umständlichkeit sorgen mag.

Arqueología de una aldea medieval y su espacio agrario: Villanueva de Santo Adriano (Asturias, noroeste de la península Ibérica)
Authors: Fernández Fernández Jesús
Published: June 2019

This article examines the causes of the establishment and temporal evolution of a medieval village in the mountainous region of Asturias, in the north-western Iberian Peninsula. A variety of methods were used for this purpose, including landscape archaeology, rural history, the study of place names and written documents, combined with archaeolog ical excavation, paleo-environmental analysis and sedimentological studies. A priority research point included the village surroundings that had been used for agricultural production; the whole area was analysed as one single object of study. This approach provided the possibility of identifying the various moments of stability and change in the landscape along with a reconstruction of the histor y of this still inhabited village and its agr icultural milieu beginning in the Early Middle Ages (eighth to eleventh centuries). Further research along the lines developed here should provide data for comparison and connect this agricultural archaeology research with the broader European framework of discussion launched in past decades.
Verification of Closed-loop Systems with Neural Network Controllers
Authors: Manzanas Lopez Diego , Musau Patrick , Tran Hoang-Dung , Johnson Taylor T.
Published: June 2019

This benchmark suite presents a detailed description of a series of closed-loop control systems with artificial neural network controllers. In many applications, feed-forward neural networks are heavily involved in the implementation of controllers by learning and representing control laws through several methods such as model predictive control (MPC) and reinforcement learning (RL). The type of networks that we consider in this manuscript are feed-forward neural networks consisting of multiple hidden layers with ReLU activation functions and a linear activation function in the output layer. While neural network con- trollers have been able to achieve desirable performance in many contexts, they also present a unique challenge in that it is difficult to provide any guarantees about the correctness of their behavior or reason about the stability a system that employs their use. Thus, from a controls perspective, it is necessary to verify them in conjunction with their corresponding plants in closed-loop. While there have been a handful of works proposed towards the verification of closed-loop systems with feed-forward neural network controllers, this area still lacks attention and a unified set of benchmark examples on which verification techniques can be evaluated and compared. Thus, to this end, we present a range of closed-loop control systems ranging from two to six state variables, and a range of controllers with sizes in the range of eleven neurons to a few hundred neurons in more complex systems.
Worst-Case Analysis of Digital Control Loops with Uncertain Input/Output Timing
Authors: Gaukler Maximilian , Ulbrich Peter
Published: June 2019

Benchmark Proposal: The implementation of digital control systems in complex multi- core or distributed real-time systems results in non-deterministic input/output timing. Such timing deviations typically lead to degraded performance or even instability, which in turn may jeopardize safety goals. We present the problem of proving worst-case guarantees for given input/output timing bounds as a benchmark for the verification of hybrid dynamical systems.

El betabel (Beta vulgaris L.) es un tubérculo que por su contenido en antioxidantes tiene propiedades preventivas de enfermedades como el cáncer, entre otras. Es consumido crudo, cocido, en ensaladas y jugos. El jugo de betabel, mantiene un alto contenido de antioxidantes, así como otros compuestos bioaccesibles que promueven la salud, pero que al ser sometido a pasteurización se generan pérdidas de estos. Actualmente existen tecnologías emergentes que brindan alternativas a las tecnologías convencionales  como lo es el ultrasonido, que se ha demostrado que libera compuestos bioactivos y mantiene la inocuidad de los alimentos. Por lo anterior, el objetivo de este estudio fue evaluar las propiedades fisicoquímicas (pH, sólidos solubles totales, acidez titulable) y microbiológicas (recuento total y enterobacterias) del jugo de betabel termoultrasonicado con variables de amplitud (80 y 90%) y tiempo (10 y 15 min). El jugo termoultrasonicado tratado a 15min/90% presentó los valores más bajos en mesófilos aerobios y enterobacterias , proporcionando mayor inocuidad, con un elevado porcentaje de estabilidad sin alterar los sólidos solubles totales, acidez y viscosidad en el jugo.

Authors: Arias-Rico J , Jiménez-Sánchez RC , Rivera-Ramírez LA , Cervantes-Yautenzi MR , Cervantes-Ortega L , Monter-Acosta D , Delgado-Serrano A , Bustamante-Mejía S
Published: June 2019

Introducción: La Organización Mundial de la Salud define la adherencia al tratamiento como tomar la medicación de acuerdo a la dosificación en el programa prescrito y la persistencia así como a lo largo del tiempo indicado. En la actualidad el desapego a los tratamientos a largo plazo es un problema que descontrola la salud del paciente. El objetivo fue identificar qué intervenciones de enfermería mejoran la adherencia al tratamiento del paciente adulto joven con VIH/SIDA. Metodología: Es un estudio cuantitativo de carácter descriptivo aplicado a una muestra de 30 pacientes de un Centro de Atención para Pacientes con VIH/SIDA. Resultados: De acuerdo con los resultados obtenidos se encuentra una adherencia al tratamiento de cumplimiento con un 36.7%. La variable de asistencia a consultas arrojó frecuentemente con un  56.7% y nunca con el 3.3% y el uso de preservativo tiene un porcentaje de 60% en siempre siendo está la más frecuente. Discusión: Se encontró que las intervenciones no tienen relevancia cuando el abandono suele deberse a factores económicos, familiares y del difícil acceso a los sistemas de salud que suelen ser los que más se presentan. Conclusión: Los resultados de la investigación arrojaron que los factores prevalentes que intervienen en la adherencia al tratamiento de los pacientes con VIH/SIDA son de tipo económico, manejo de emociones, ingesta inadecuada del tratamiento y la inasistencia periódica a las consultas. Las intervenciones de enfermería que mejoraron la adherencia al tratamiento, fueron la educación, la información de la enfermedad y el apoyo emocional.

Stumbling Along, Walking on Eggshells and Vicious Circles: What Happens while Families Wait for Youth Substance Use Treatment
Authors: Mills Laura , Dionne Alexandre , Bingley Jennifer , Watson Shelley L.
Published: June 2019

Youth substance use is a serious problem that has immediate and long-term impact on individuals, families, and society. Adolescent substance experimentation that develops into abuse foreshadows long-term problems, such as adult addiction, co-occurring mental illness, declined or abandoned academic careers, and other individual and interpersonal harms. Early and effective intervention can mitigate the harmful effects on the lives of young people, their families, and their communities. Intervention may not be accessible, however, for adolescents and/or their families when they seek help, and wait lists are common. Waiting for treatment for substance use is the focus of this study, and in particular, the experience of waiting and its associated impacts on the youth’s substance use, involvement with police, running away, mental health and on the family unit. 118 parents of youth who use substances participated in a mixed methods study at Pine River Institute, a long-term residential youth treatment center. Clinical implications are discussed.
Increasing immunization compliance among schools and day care centers: Evidence from a randomized controlled trial
Authors: Leight Jessica , Safran Elana
Published: June 2019

This paper reports on the results of a randomized controlled trial in which researchers collaborated with a department of health in a mid-size city to evaluate the effectiveness of targeted communications highlighting descriptive social norms to increase immunization compliance across 700 schools. Schools were randomly selected to receive a twice-annual immunization compliance report card reporting in detail their compliance rates compared to other schools of the same school type; the comparison rates reported included the school-type average, average compliance among the top 10% of performers, and the city target of 98% compliance. Shifts in immunization compliance are tracked in a city-wide administrative vaccine registry. The results suggest that there was no significant difference in compliance rates between treatment and control schools six months post-treatment. To our knowledge, it is the first randomized controlled trial evaluating the use of descriptive social norms in increasing immunization compliance rates in a school-based setting. In addition, it serves as an example of embedding a behaviorally-informed experiment in a government program utilizing high-quality administrative data.
АДАПТИВНИЙ МОНІТОРИНГ СТРАТЕГІЙ ФОРМУВАННЯ АНТИКРИЗОВОГО ПОТЕНЦІАЛУ
Authors: Ареф’єв Сергій Олегович
Published: June 2019

The paper covers the current issues of counteraction to constantly arising crisis phenomena in the process of using the enterprise potential. For about 15 years the efforts to comply with legislation have been steadily rising, and more and more emphasis is paid to various aspects of corporate social responsibility. There is a wide range of activities, such as increasing employee awareness, creating a management system to prevent abrupt changeover, a solid corporate structure and timely disclosure of information, as well as managing the organization as an integration of its potentials. Adaptive monitoring is viewed as a critical component in finding and controlling the reserves for further utilization of enterprise resources in the context of developing its long-term strategies. Building the subsystems for change management strategies can form the basis for creating anti-crisis potential. However, there is another barrier to the process of adaptation which is a vulnerable internal environment. Apparently, the goals of the chosen strategies in each of the business areas are not always announced, and this can increase the entropy level within the enterprise, creating threats and hazards that give rise to crisis phenomena. From a dynamic perception, adaptive management concept involves the construction of a decomposition of its possible implementation scenarios subject to the type of threats to enterprise performance and characteristics of its potentials. The search for the development models that can retain the enterprise resources is a fundamental challenge for its operation in the future. It is about facilitating the transition from product economy to the system economy, from a dissipative approach to resources to an adaptive management practices, to a cultural leap towards economic and environmental sustainability that should affect the entire society, from strengthening of the territory and cooperation among all stakeholders to gain the resource utilization efficiency beyond renewable energy, starting with raw materials and local waste management to create an integrated technology network and from a number of integrated technologies, from deindustrialized territories reconstruction towards new relationships between agriculture, industry and academia, conducting local case studies to test the effects of innovations, thus boosting the process of transforming the research results into new pilot projects.

The paper explores the existing concepts of sales, sales policy and sales promotion, in particular, specifies the definition of a marketing sales policy concept as well as provides insights about the role and significance of marketing sales promotion policy. The study discusses a range of issues related to challenges in enhancing company’s competitiveness, identifies advantages and disadvantages of sales promotion along with revealing the most effective distribution channels in terms of various marketing communication tools. Specific advantages and disadvantages of particular forms and methods of sales, such as personal selling and selling via the Internet are considered. Within the context of sales promotion, special emphasis is put on the effect of such market drivers as price increase, impulsive buying tendency, increased competition, dramatic socioeconomic tension, etc. It is argued that sales policy of enterprises should rely on their respective marketing strategies, viewed as a set of tactical measures and actions to generate demand. To understand the root causes and prerequisites for the active use of sales promotion instruments in the marketing promotion mix, their core benefits and limitations have been exposed. Among a vast range of sales promotion tools, their common specific characteristic is the focus for gaining rapid sales growth in a short period of time. Thus, the research findings have revealed that this type of marketing communication as an element of integrated promotion strategy seems promising and effective, given the prompt and positive significant outcomes in the short term, and with careful planning and regular application it can lay a good background for a long-term brand loyalty. To achieve the most effective results from the implementation of sales promotion techniques, it is critical to develop a clear and specific sales promotion strategy that will entail information about the ultimate goal, tools, characteristics and the budget of the sales promotion mi, as well as the results from the sales program testing, monitoring and assessment.

Is Equal Pay Worth it?
Authors: Chassonnery-Zaïgouche Cléo
Published: June 2019

The paper describes the personal and intellectual trajectories of Millicent Fawcett, Beatrice Webb and Eleanor Rathbone that led them to first oppose the "equal pay for equal work" principle and to support it after the first world war. I focus on their changing economic arguments in relation to their perception of the "facts" regarding women's work and wages during the war effort.
An Analysis of Design Process and Performance in Distributed Data Science Teams
Authors: McComb Christopher , DeFranco Joanna , Maier Torsten
Published: June 2019

Purpose – Often, it is assumed that teams are better at solving problems than individuals working independently. However, recent work in engineering, design, and psychology contradicts this assumption. This work examines the behavior of teams engaged in data science competitions. Crowdsourced competitions have seen increased used for software development and data science, and platforms often encourage teamwork between participants.Design/methodology/approach – We specifically examine teams participating in data science competitions hosted by Kaggle. We analyze data provided by Kaggle to compare the effect of team size and interaction frequency on team performance. We also contextualize these results through a semantic analysis.Findings – This work demonstrates that groups of individuals working independently may outperform interacting teams on average, but that small, interacting teams are more likely to win competitions. The semantic analysis revealed differences in forum participation, verb usage, and pronoun usage when comparing top- and bottom-performing teams.Research limitations/implications- These results reveal a perplexing tension that must be explored further: true teams may experience better performance with higher cohesion, but nominal teams may perform even better on average with essentially no cohesion. A limitation of this research includes not factoring in team member experience level and reliance on extant data.Originality/Value – These results are potentially of use to designers of crowdsourced data science competitions as well as managers and contributors to distributed software development projects.
Medial and lateral orbitofrontal cortices represent unique components of cognitive maps of task space
Authors: Bradfield Laura , Hart Genevra
Published: June 2019

The orbitofrontal cortex (OFC) has recently been proposed to function as a cognitive map oftask space: a mental model of the various steps involved in a task. This idea has proven popularbecause it provides a cohesive explanation for a number of disparate findings regarding the OFC’srole in a broad array of tasks. Concurrently, mounting evidence has begun to reveal the functional heterogeneity of OFC subregions, particularly the medial and lateral OFC. How these subregions might uniquely contribute to the OFC’s role as a cognitive map of task space, however, has not been explored. Here we propose that the lateral OFC represents the agent’s initial position within that task map (i.e. initial state), determining which actions are available as a consequence of that position, whereas the medial OFC represents the agent’s desired future position within the task map(i.e. terminal state), influencing which actions are selected to achieve that position. We argue thatthese processes are achieved somewhat independently and somewhat interdependently, and are achieved through similar but non-identical circuitry.
Gift-Commodity Entanglements: Repositioning (In)Formality in a Transnational Philippine Market Trade
Authors: Milgram B. Lynne
Published: June 2019

Filipinos working abroad, known as Overseas Filipino Workers, regularly send cash remittances and in-kind gifts (for example, cosmetics, vitamins, clothing) to family in the Philippines. These gifts are not subject to customs duties because, like cash, they contribute to the Philippine economy and provide family members with needed goods. However, because state economic policies have failed to adequately meet citizens’ subsistence requirements, Philippine gift recipients and entrepreneurs in Baguio, northern Philippines, for example, operationalise this transnational flow of goods by diverting selected gifted products into grey spaces of public market trade – transactions that straddle informal/formal and gift/commodity practice and that are sometimes extralegal in nature. Baguio residents who cannot use the gifted goods they receive, for example, may sell or exchange them in commodity transactions at public market stores. Entrepreneurs, in turn, nurture good customer relations by gifting income from these sales, as well as goods, to community welfare initiatives. Simultaneously, depending upon the government’s agenda, officials variably permit or restrict the tax-free import and sale of gifted goods. Given that overseas cash remittances and in-kind gifts continue to support the Philippine economy, I argue that government and entrepreneurs are complicit in using informality as an urban organizing logic when this practice is to their respective advantage.
Winking at Humanitarian Neutrality: The Liminal Politics of the State in Lebanon
Authors: Carpi Estella
Published: June 2019

Drawing on the July 2006 Israel–Lebanon War in Beirut’s southern suburbs and the Syrian refugee influx into the villages of Akkar in northern Lebanon, I suggest that the Lebanese state aspires to officially assert itself as a liminal space in a bid to survive crises and preserve its political capital, therefore aborting the attempts made by citizens and refugees to leave such liminality. I look at how professed state liminality meets with humanitarian neutrality, which is a principle of several international humanitarian agencies that assisted the internally displaced in 2006 and Syrian refugees from 2011 in Lebanon. Although in anthropology liminality has mostly been approached as anti-structural and an embodiment of the margins, by proceeding from people’s perception of state enmity and their frustrated aspirations to befriend the state, I suggest that state liminality rather captures the structural peculiarity of the Lebanese state’s agency and violent presence, made of repressive and neglectful politics.

It is important to establish the quantitative effect of graphite's 3D morphology on the thermal conductivity of vermicular graphite iron. In the present study, X-ray tomography is utilized to investigate the 3D morphology of graphite in vermicular graphite iron with different vermicularity. A 3D finite element model was built on the basis of graphite's 3D morphology and the equivalent thermal conductivity of vermicular graphite iron can be calculated. The results show that the volume of graphite clusters in vermicular graphite iron is distributed according to y = a (1 − e−bx)c exponential function. The higher the vermicularity, the more obvious the polarization of graphite volume. Compared with vermicularity, 3D connectivity of graphite is a more appropriate characteristic parameter to investigate the thermal conductivity of vermicular graphite iron from the 3D morphology point of view.

Published: June 2019

In this paper, the effects of copper addition (0–2.0 wt.%) on the microstructure and properties of carbidic austempered ductile iron were studied using an optical microscope, a scanning electron microscope, a Rockwell hardness tester, a pendulum impact tester, an X-ray diffractometer, a block-on-ring wear testing machine and an electrochemical tester. The amount of carbides and graphite nodules simultaneously decreased with the increase in Cu content. Cu also improved the nodularity of graphite, made the graphite nodules grow, increased the pearlite content and refined the pearlite. After austenitizing (900°C / 100 min) and austempering (300°C / 100 min), the amount and size of the acicular ferrite significantly reduced with the addition of Cu. In contrast, the amount of retained austenite dramatically increased, and the carbon content in retained austenite slightly increased. The hardness of carbidic austempered ductile iron had no obvious change with the increase in Cu content. The wear resistance of carbidic austempered ductile iron first increased and subsequently decreased, and the impact toughness and corrosion resistance were improved with the increase in Cu content. The comprehensive properties of carbidic austempered ductile iron were optimal, with the Cu content of 1.0 wt.%.
