The paper presents results of research on the effective ways and means for tillage and seeding in the cultivation of crops in drought weather conditions. In order to improve the treatment quality, moisture-accumulating capacity and water saving of the soil in cropping technology with minimum tillage, including its final (finish) preparation for sowing with lower power consumption, we proposed new tillage methods. The first method involves post-harvest surface moisture-challenging loosening the stubble to a depth of 3-5 cm, the main non-recourse autumn moisture-absorbing loosening to a depth of 20-30 cm, deep moisture-accumulating Diesel hoeing to a depth of 40-65 cm, the spring surface moisture-closing loosening to a depth of 4-5 cm and moisture-mulching pre-sowing tillage to a depth of 4-5 cm with a seal seed bed and combing the weeds in the stage of “white thread”. The second method comprises the moisture-accumulating phase, which is performed in the autumn, when in the soil a vertical slit with a controllable pitch was made by spade working units and placing them in a staggered manner. Then we perform a second spring moisture-saving phase by solid surface loosening and mulching with rotary tools with working units to a depth of seeding. So that to implement the proposed methods the authors developed a set of tillage and seeding equipment (69 types of devices, 30 types of working units, 35 types of plug-in modules). Their production was mastered. The developed machines provide higher yields by 5 kg per hectare, reduce energy and labor costs up to 50%, have a competitive advantage over domestic and foreign counterparts.

Authors: Гозалова Марина , Gozalova Marina
Published: March 2017

The article focuses on research into project work as a learner’s activity contributing to the development and refinement of his / her communicative competence.

The author states that, besides improving a learner’s linguistic competence and promoting his/her involvement with the learning process, project work favourably affects both communication standards and, more broadly, social behavior through providing ample room for cooperation, empathy, creativity, and individual contribution. Thus, embracing project work and making it part of the foreign language teaching routine will ensure that learners acquire communicative competence at a level that meets current requirements.
On professional identity of English language teachers
Authors: Чудайкина Галина , Chudaykina Galina
Published: March 2017

A vast majority of English language teachers in Russia are not native speakers with no or inadequately little personal experience of living in an English-speaking country. What are the specifics of teaching in view of such an authenticity-lacking professional background, and how does the personality of a teacher reveal itself and is transformed in the course of teaching? How does language teaching affect self-identification? What should a teacher focus on attaining or, by contrast, avoiding in view of the above-raised issues? A significant number of foreign language teachers who are not native speakers demonstrate a clear non-target-language-specific accent, thus, either inadvertently or purposefully, revealing and asserting their national identity. The author of the article aims at identifying the problems that the teacher’s explicit target-language-alien accent may cause to both learners and teachers, and the root causes of the accent resilience.

Authors: Шириязданов  , Shiriyazdanov Rustem
Published: March 2017

Lack of accommodation of powertrains characteristics of mobile machines with the conditions of their operation in the agricultural sector leads to several problems. The aim of this study was chosen to create an approach to harmonize the characteristics of mobile machines powertrains with the conditions of their operation in the agricultural sector, which would allow to increase the efficiency of these machines due to: taking into account engine modes and transmission, peculiar to real operating conditions; taking into account the influence of the control action on the engine operation modes and transmission (partial work on high-speed mode); taking into account the influence of external constraints (requirements, efficiency criteria) on the engine operation modes the and transmission; the possibility of using operational means of establishing characteristics in the early stages of designing. A number of tasks were solved: 1) Creation of a mathematical model of the system, including the powertrain, the mobile machine operating conditions and control actions; 2) Collection of experimental data to verify the adequacy of the model; 3) Conducting computational experiments; 4) Optimization model for applications. Using the developed model, it becomes possible for any unit of the “powertrain - mobile machine – operation environment” system to set design requirements for specific operating conditions, as well as the laws of control of system components. The methods of applications of the model, the specific algorithms of system control for applications were developed.

Examining Alliance Portfolios Beyond the Dyads: The Relevance of Redundancy and Nonuniformity Across and Between Partners
Authors: Hoehn-Weiss Manuela N. , Karim Samina , Lee Chi-Hyon
Published: March 2017

In this research, we unpack how interdependencies affect not just individual dyads but also value creation across an alliance portfolio and ultimately a focal firm’s performance. Moving beyond the collection of dyadic relationships of individual alliances, we examine more holistically the distribution of power imbalances and mutual dependences within alliance portfolios, as well as the impact of redundancies in portfolio partners’ resources. Building on resource dependence theory, we develop and test arguments on a sample of 59 firms in the U.S. passenger airline industry during 1998–2011. We find that nonuniform distributions of power imbalances and mutual dependences within the alliance portfolio as well as redundancy affect firm performance in different ways, which has implications for the management of alliance portfolios.

Learning from mistakes: the use of significant event audit in veterinary practice
Authors: Mosedale Pamela
Published: March 2017

All veterinary surgeons should involve themselves in clinical governance. Clinical audit can be used to monitor the quality of care in a practice. Significant event audit is a qualitative form of clinical audit. It starts with a no-blame meeting of the practice team; this looks at what happened, why it happened, what has been learned and what needs to change. The results can be that training needs are identified, protocols are changed or drawn up considering the evidence base, and further audits may be planned. Significant event audit is about improving systems, not about blaming individuals.
Local bisphosphonate reduces migration and formation of radiolucent lines adjacent to cemented acetabular components
Authors: Schilcher J. , Palm L. , Ivarsson I. , Aspenberg P.
Published: March 2017

Aims

Post-operative migration of cemented acetabular components as measured by radiostereometric analysis (RSA) has a strong predictive power for late, aseptic loosening. Also, radiolucent lines predict late loosening. Migration has been reduced by systemic bisphosphonate treatment in randomised trials of hip and knee arthroplasty. Used as a local treatment, a higher local dose of bisphosphonate can be achieved without systemic exposure. We wished to see if this principle could be applied usefully in total hip arthroplasty (THA).

Patients and Methods

In this randomised placebo-controlled, double-blinded trial with 60 participants, we compressed gauze soaked in bisphosphonate solution (ibandronate) or saline against the acetabular bone bed immediately before cementing the acetabular component. RSA, classification of radiolucent lines, the Harris Hip Score (HHS) and the Western Ontario McMasters Universities Osteoarthritis Index (WOMAC) were carried out at three-, six-, 12-, and 24-month follow-up.

Results

Migration of the cemented acetabular component relative to the pelvis was reduced by movement almost half in the ibandronate group, when measured as maximum total point or as movement of the femoral head (p = 0.001 and 0.004, respectively). Radiolucent lines after one year were classified as absent, partial or complete, and correlated with treatment (rho 0.37; p = 0.004). Only three of 30 patients in the ibandronate group had complete lines, compared with 13 of 28 in the placebo group (p = 0.002). There were no significant effects on HHS or WOMAC score.

Conclusion

Considering the power of RSA to predict loosening of cemented acetabular components, and the likelihood that radiolucent lines indicate risk of loosening, these data suggest that local treatment with a bisphosphonate can reduce the risk of late aseptic loosening.

Explant analysis of the Biomet Magnum/ReCap metal-on-metal hip joint
Authors: Scholes S. C. , Hunt B. J. , Richardson V. M. , Langton D. J. , Smith E. , Joyce T. J.
Published: March 2017

Objectives

The high revision rates of the DePuy Articular Surface Replacement (ASR) and the DePuy ASR XL (the total hip arthroplasty (THA) version) have led to questions over the viability of metal-on-metal (MoM) hip joints. Some designs of MoM hip joint do, however, have reasonable mid-term performance when implanted in appropriate patients. Investigations into the reasons for implant failure are important to offer help with the choice of implants and direction for future implant designs. One way to assess the performance of explanted hip prostheses is to measure the wear (in terms of material loss) on the joint surfaces.

Methods

In this study, a coordinate measuring machine (CMM) was used to measure the wear on five failed cementless Biomet Magnum/ReCap/ Taperloc large head MoM THAs, along with one Biomet ReCap resurfacing joint. Surface roughness measurements were also taken. The reason for revision of these implants was pain and/or adverse reaction to metal debris (ARMD) and/or elevated blood metal ion levels.

Results

The mean wear rate of the articulating surfaces of the heads and acetabular components of all six joints tested was found to be 6.1 mm3/year (4.1 to 7.6). The mean wear rate of the femoral head tapers of the five THAs was 0.054 mm3/year (0.021 to 0.128) with a mean maximum wear depth of 5.7 µm (4.3 to 8.5).

Conclusion

Although the taper wear was relatively low, the wear from the articulating surfaces was sufficient to provide concern and was potentially large enough to have been the cause of failure of these joints. The authors believe that patients implanted with the ReCap system, whether the resurfacing prosthesis or the THA, should be closely monitored. Cite this article: S. C. Scholes, B. J. Hunt, V. M.

Socialización de información y movilización de las víctimas. Estrategias regionales de defensa de los derechos humanos frente a la violencia en México
Authors: López Jairo Antonio
Published: March 2017

El principal cuerpo de literatura que estudia la acción colectiva de las organizaciones no gubernamentales de derechos humanos pone un énfasis especial en las grandes organizaciones internacionales y las organizaciones ubicadas en las capitales de los Estados. Cuestionando este énfasis, en el presente artículo analizamos la movilización en defensa de los derechos humanos de las organizaciones locales frente a la violencia en México. Planteamos que estos actores colectivos impulsaron la socialización de información confiable sobre la crisis de derechos humanos y un trabajo directo de movilización con las víctimas y sus familiares, como nuevas estrategias de demanda frente a la violencia desatada tras las políticas de militarización. A partir de entrevistas a líderes de organizaciones, el análisis cronológico de prensa y de documentos oficiales de las organizaciones, identificamos que estas estrategias se evidencian en la creación de redes y acompañamiento regional, el posicionamiento de las agendas locales ante el Sistema Interamericano de Derechos Humanos y la emergente coordinación frente a la crisis de desaparición forzada. La movilización de organizaciones locales y de las víctimas ha sido soporte de las críticas que se han desatado frente al gobierno federal a nivel nacional e internacional luego de la desaparición de los 43 normalistas de Ayotzinapa, generando un claro episodio de presión y reconocimiento de la crisis de derechos humanos que vive México.
El arte como tecnología de la identidad: de la obra a la instalación
Authors: Martínez de Albeniz Iñaki
Published: March 2017

El artículo plantea, desde la sociología del arte, un recorrido por el arte vasco contemporáneo que tiene como fin analizar hasta qué punto las artes plásticas han operado, en el contexto vasco, como tecnologías de la identidad, esto es, cómo se ha producido identidad mediante determinados artefactos artísticos. Sin embargo, no es hasta recientemente, con el advenimiento de las post-vanguardias, que el propio proceso de construcción identitaria a través del arte se hace reflexivamente explícito y pasa a formar parte del repertorio de los artistas. El texto echa mano de la dicotomía obra/instalación para analizar este salto en las concepciones del arte y la identidad (y su mutua relación): el paso de un arte moderno, basado en la producción de obras cuya función es representar determinada “manera de ser”, a un arte post-moderno que hace visibles en la propia obra los procesos a través de los cuáles algo “llega a ser” a resultas de la movilización de recursos artísticos con vocación deconstructiva.
Proposição de metodologia para análise de risco em estruturas de pavimentos asfálticos flexíveis
Authors: Ferri Santi , Suzuki Carlos Yukio , Kabbach Junior Felipe Issa , Santos Caio Rubens Gonçalves , Vallejo Flaviane Melo Lopes
Published: March 2017

A concepção de empreendimentos de infraestrutura viária envolve diversas fases de planejamento, estudos e pro-jetos. Nestas fases normalmente são discutidas e definidas as possíveis soluções de engenharia a serem aplicadas em cada etapa executiva. Para que as soluções definidas nas fases de planejamento e projeto tenham validade, faz-se necessário ga-rantir que os recursos utilizados, como materiais, mão de obra, máquinas, equipamentos e processos executivos empregados no campo atendam aos pré-requisitos técnicos especificados em projeto. Ocorre, porém, que no Brasil e em outros países do mundo, muitos dos métodos empregados para o dimensionamento de estruturas de pavimentos asfálticos são de natureza determinística, ou seja, utiliza-se de parâmetros médios para caracterização mecânica da estrutura não se preocupando em quantificar os prejuízos ocasionados pela variação de parâmetros proveniente do processo executivo. Na prática, como todo processo industrial, os processos construtivos estão sujeitos a apresentar variações que devem sempre ser aferidas e contro-ladas para garantir a qualidade do produto final. Dentro deste contexto, o presente trabalho apresenta uma metodologia de-senvolvida para realizar análises de risco de estruturas de pavimentos asfálticos flexíveis com base em critérios mecanicistas correntemente utilizados no Brasil. Com base nos estudos de caso realizados, verificou-se que a metodologia proposta apre-senta boa aplicação prática tanto nas fases de projeto quanto nas fases de controle de qualidade de camadas de infraestrutura de pavimentos recém-executadas.
Avaliação dos efeitos da radiação ultravioleta sobre propriedades reológicas de ligantes asfálticos modificados com PPA e copolímeros SBS e SBR
Authors: Nascimento Thalita Cristina Brito , Faxina Adalberto Leandro
Published: March 2017

O envelhecimento dos ligantes asfálticos afeta diretamente as propriedades mecânicas das misturas asfálticas. Neste sentido, as especificações limitam determinados índices ou parâmetros de envelhecimento, visando contornar o endurecimento excessivo do ligante asfáltico. No entanto, as especificações para ligantes asfálticos não levam em consideração o efeito da radiação ultravioleta (UV) sobre as propriedades reológicas dos materiais. Os objetivos deste trabalho são (i) quantificar os efeitos da radiação UV sobre as propriedades reológicas de um CAP 50/70 e cinco ligantes asfálticos modificados com PPA e os copolímeros SBS e SBR (CAP+PPA, CAP+SBS, CAP+SBS+PPA, CAP+SBR e CAP+SBR+PPA) e (ii) comparar os níveis de envelhecimento decorrentes da radiação com o envelhecimento na estufa PAV. Os ligantes asfálticos envelhecidos na estufa PAV e sob radiação UV foram previamente envelhecidos na estufa RTFO. As modificações proporcionaram materiais mais resistentes ao envelhecimento a longo prazo, tanto na estufa PAV quanto no wetherometer (radiação UV), destacando-se o CAP+SBR+PPA.

Authors: Petzhold Guillermo , Lindau Luis Antonio
Published: March 2017

Organizações desempenham um papel fundamental em questões atreladas ao transporte. Por volta de 50% dos deslocamentos diários nas cidades brasileiras ocorrem por motivo de trabalho. O conceito de mobilidade corporativa ainda é incipiente no país, embora difundido internacionalmente. A elaboração de planos de mobilidade corporativa estimula hábitos mais sustentáveis e eficientes de deslocamentos ao trabalho. Através da análise de 16 métodos de países onde o conceito já está estabelecido, propõe-se um roteiro adaptado à realidade local que conduza organizações no desenvolvimento desses planos. O método se diferencia em seis principais pontos frente aos analisados: (i) identificação da necessidade, (ii) mapea-mento dos atores envolvidos, (iii) definição do escopo e reavaliação das metas iniciais, (iv) protagonismo da comunicação, (v) necessidade de cooperação técnica e (vi) coleta de dados sobre custos. Através do método proposto, espera-se influenciar organizações a desenvolverem planos de mobilidade corporativa que venham a beneficiar funcionários, as próprias organi-zações e as cidades.
Influência do teor de umidade, da porosidade e do intervalo de tempo até a aplicação da mistura solo-cimento em pavimento rodoviário

Published: March 2017

Pretende neste trabalho avaliar a influência do teor de umidade, da porosidade e do intervalo de tempo até a aplicação, sobre a resistência à compressão simples (RCS) de misturas de solo-cimento. Foram realizadas três baterias de ensaios, usando misturas de solo-cimento compactadas, com 6 e 7 % de cimento. Na primeira bateria foi utilizada a umidade ótima (wótima) e energia Normal de Proctor, na segunda usou-se wótima + 1 % e energia Normal de Proctor e na terceira foi utilizada a wótima + 1 % e energia de compactação alterada, a fim de verificar a influência do teor de umidade. Para cada dosagem as compactações ocorreram em 10 intervalos de tempo até a aplicação, variando de 0 min a 6 h, com o intuito de verificar, no desempenho mecânico, a influência do intervalo de tempo até a aplicação do solo-cimento. Os resultados apon-taram que o aumento no intervalo de tempo até a aplicação diminui a RCS e este tempo é limitado para atingir a RCS mínima requerida de 21 kg/cm², variando conforme o teor de cimento, teor de umidade e energia de compactação. Quando a com-pactação se deu com wótima + 1 % foram obtidos maiores valores de RCS, para os mesmos tempos de aplicação. Em todas as dosagens verificou-se que quanto mais baixa a porosidade da mistura solo-cimento melhor foi o desempenho mecânico.

Published: March 2017

Nos últimos anos a exportação de commodities agrícolas e minerais vem crescendo no Brasil e isto tem levado a um aumento de demanda de transporte ferroviário. Assim, é importante que modelos matemáticos sejam propostos para o planejamento da circulação dos trens que tenham por objetivo o aumento da quantidade de trens circulando na ferrovia. Desta forma, este artigo apresenta um modelo matemático baseado no modelo Job Shop para o Problema de Planejamento da Circulação de Trens em uma ferrovia de linha singela. O modelo proposto permite que os trens sejam atrasados ou adiantados na partida visando reduzir o tempo parado em pátios de cruzamento. O modelo foi resolvido utilizando CPLEX 12.6 e testes foram realizados com dados reais da Ferrovia Centro Atlântica (FCA). Os resultados do modelo foram comparados com os resultados da FCA e em todos os cenários testados o modelo obteve redução do tempo de viagem dos trens.
Vom langen Jetzt

Das Jetzt erscheint als Paradoxie - es ist ausdehnungslos und doch werden ihm kontingente Längen auferlegt. Wie ist seine Paradoxie zwischen Kürze und Länge denkbar, wenn sie mit dem langen Jetzt noch verstärkt wird? Vera Fischer wagt ein Denken der Paradoxie entlang des weitgehend unerschlossenen kalifornischen Phänomens »The Long Now Foundation«. Deren Protagonisten, die einst der Hippie-Bewegung angehörten, setzen sich mit einer aberwitzigen Geschäftsidee in Szene. Die Zeitreise zur »Long Now Foundation« legt deren medienkulturelle Bedeutung frei - sie ist ein Beitrag zum Umgang mit Gegenwart und zugleich ein spielerischer Trip durch die Komplexität der Paradoxie, die unsere Vorstellungen herausfordert.

Phytochemical, antimicrobial and nutritional properties of Morinda lucida benth and Nauclea latifolia leaf extracts
Authors: Enabulele Stephen , Amusa Oluwatosin , Uwadiae Eseosa
Published: March 2017

The leaves of two medicinal plants namely; Morinda lucida and Nauclea latifolia were investigated for their antibacterial, mineral and phytochemical properties. Results of the study showed that the aqueous and ethanolic extract of the two leaves had significant antibacterial activity against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Listeria monocytogenes and Proteus mirabilis. The biologically active constituents present in the extracts were cardiac glycosides, tannins, saponin, coumarins, reducing sugar, terpenoids, alkaloids, steroids and flavonoids. The percentage yield extracts of the respective plants were Morinda lucida leaves 12.9% for ethanol and 9.0% for aqueous extracts while Nauclea latifolia had 12.1% for ethanol and 8.4% for aqueous extracts. Results of the antibacterial activity analysis revealed that the ethanolic extracts of the two medicinal plants at different concentrations were more active against the test organisms named above than the aqueous extracts. The MIC values for the ethanolic extracts ranged between 25.0 and 100.0 mg/ml while that of aqueous extract ranged between 50.0 and 100.0 mg/ml. The MBC values for ethanolic extract ranged between 50.0 and 100mg/ml while that of aqueous extracts also ranged between 50.0 and 100mg/ml. Analysis of the mineral content of the plant leaves shows that they were rich in potassium and calcium. This study confirms that the leaf extracts have some reasonable level of antimicrobial activity and appreciable amounts of mineral content which could be beneficial to human health. The findings from this work can be further exploited for isolation and characterization of novel Phytochemical compounds which could be used in the treatment of infectious diseases especially in light of the emergence of drug-resistant microorganisms and the need to produce new effective antimicrobial agents.
Organisms and Objectifications: A Historical-Materialist Inquiry into the 'Human and Animal'

The anthropocentric tendency to view nature or the environment as everything that is not human obscures the productive processes that go on in "nature." But non-human animals are also the purposeful producers of their own worlds: they too engage in their own species-specific objectifying activity that transforms what is, from their perspective, nature; they too build worlds in their own bodily image.Click here to purchase a PDF version of this article at the Monthly Review website.

We're seeing the possibility of regenerating a left that has previously been ground down to the scale of atoms, one that, if it adapts creatively to the coming defeats, can prepare the ground for success. But that means recognizing that the history of the left is a history of defeats; it is a history of the vanquished.Click here to purchase a PDF version of this article at the Monthly Review website.

Conflict as a phenomenon is one of the basic dynamics of life.  It forms the basis of human relations and communication as an inescapable fact that people frequently face during any period of their life. In inter-personal relations, listening and conflict management tendencies may be described as major variables affecting the quality and type of the relationship. This study is to examine the relationship between teacher candidates’ listening skills and their conflict management styles. In this study, the data concerning teachers’ listening skills were obtained through “Listening Skill Scale” of Cihangir-Çankaya (2012) whereas data regarding their conflict management styles were obtained through “Interpersonal Conflict Management Styles Scale” that had been developed by the researchers. Both scales were used for 491 teacher candidates who were taking courses for pedagogical formation in Faculty of Education of Ondokuz Mayıs University during 2015-2016 academic year. In the consequence of the analyses made, a statistically significant relationship was found between teacher candidates’ listening skills and their choices about conflict management styles. A low-level negative relationship was determined between teacher candidates’ listening skills and their accommodating and forcing (competing) styles, while a mid-level positive relationship was found out between listening skills and their compromising and problem-solving (integration) styles.  ÖzetÇatışma olgusu, yaşamın temel dinamiklerinden biridir. Yaşamın her kesitinde sürekli karşı karşıya bulunduğumuz ve kaçınamayacağımız bir gerçek olarak çatışma, insan ilişkilerinin ve iletişimin odağında yer alır. İletişimin olmazsa olmazı olarak dinleme ve çatışmayı yönetme eğilimleri bireyler arası ilişkilerde, ilişkinin niteliğini ve biçimini etkileyen ana değişkenler olarak nitelendirilebilir. Bu çalışmada öğretmen adaylarının dinleme becerileri ile çatışmayı yönetme biçimleri arasındaki ilişki incelenmiştir. Bu çalışmada öğretmen adaylarının dinleme becerilerine ilişkin veriler; Cihangir-Çankaya’nın (2012) “Dinleme Becerisi Ölçeği”, çatışmayı yönetme biçimlerine ilişkin tercihleri ise araştırmacılar tarafından geliştirilen “Bireyler Arası Çatışmaları Yönetme Biçimleri Ölçeği” kullanılarak elde edilmiştir. Her iki ölçek, 2015-2016 öğretim yılında Ondokuz Mayıs Üniversitesi Eğitim Fakültesinde pedagojik formasyon eğitimi alan 491 öğretmen adayına uygulanmıştır.  Yapılan analizler sonucunda; öğretmen adaylarının dinleme becerileri ile çatışmaları yönetme biçimlerine ilişkin tercihleri arasında istatistiksel olarak anlamlı bir ilişki olduğu bulunmuştur.  Öğretmen adaylarının dinleme becerileri ile çatışmayı yönetme biçimlerinden uyum ve hükmetme arasında negatif yönde düşük, uzlaşma ve sorun çözme (tümleştirme) biçimleri arasında ise pozitif yönde orta düzeyde ilişki bulunmuştur.

The ability to better understand tropical peat ecosystems for restoration and climate change mitigation is often hampered by the lack of availability accurate and detailed data on vegetation cover and hydrologys, which is typically only derived from detailed and high-resolution imaging or field-based measurements. The aims of this study were to explore the potential advantage of airborne discrete-return lidar for mapping of forest cover in peat swamp forests. We used 2.8 pulse.m-1 lidar and the associated 1-m DTM derived from an airborne platform. The lidar dataset fully covered a 120 thousand hectare protection forest in Central Kalimantan. We extracted maximum vegetation heights in 5-m grid resolution to allow detailed mapping of the forest. We followed forest definition from FAO for forest and non-forest classification. We found that lidar was able to capture detail variation of canopy height in high-resolution, thus provide more accurate classification. A comparison with existing maps suggested that the lidar-derived vegetation map was more consistent in defining canopy structure of the vegetation, with small standard deviations of the mean height of each class.
Doxa of Shareholders and Owners: On the Threshold of Financialization
Authors: Jonnergård Karin , Larsson-Olaison Ulf
Published: March 2017

Following financialization, there has emerged an understanding of what it implies to be a shareholder based on the shareholder value perception. However, as this shareholder value perception spreads internationally, it clashes with traditional perceptions. In this paper, we apply the language developed by Bourdieu to a Swedish public debate on equal treatment of shareholders in connection with the reform of the Swedish market for corporate control. Using Bourdieu’s conceptual framework, we describe how a global development interacts with the persistence of national practices. We conclude that in Sweden, local institutional investors have allied themselves with international institutional investors to enhance their positions in the restricted field of Swedish corporate control. Shareholder value is then used by these local actors as an argument to strengthen their position. At the same time, some of the controlling shareholders depart from their traditional position as industrial entrepreneurs and embrace a more financial approach to ownership, thereby altering both the power constellations and the capital, in Bourdieu’s sense, of the field.

A Markov-switching regression model with non-Gaussian innovations: estimation and testing
Authors: De Angelis Luca , Viroli Cinzia
Published: March 2017

In this paper we propose a very general multivariate Markov-switching regression (MSR) model considering the normal inverse Gaussian (NIG) distribution as conditional form of financial returns and model innovations. It is indeed well-known that the Gaussian distribution is not able to capture many stylized facts of the return series such as skewness, excess kurtosis and heavy tails. Through a large simulation study and an empirical analysis of the US stock market, we show that a NIG-based MSR model allows to adequately account for both skewness and fat tails in the data and, according to model selection criteria, is the best overall model in the majority of the cases considered, even preferred over other popular distributional assumptions such as Student-
Highly active and stable protease production by an extreme halophilic archaeon Haloarcula sp. TG1 isolated from Lake Tuz, Turkey

Published: March 2017

Objective

Isolation of halophilic microorganisms from Çankırı salt mine and Lake Tuz in Turkey to explore versatile protease producers for industry and characterization of protease enzyme from the best protease producer among the isolated strains.

Methods

Extreme halophiles were isolated from salt samples of Çankırı salt mine and Lake Tuz. Their protease activities were determined. The isolate with the highest protease activity was characterized. Its protease activity was evaluated in different NaCl concentrations, temperature and pH ranges, and in the presence of different inhibitors and metals. Thermostability and pH stability were also determined.

Results

The highest protease producer strain was identified as Haloarcula sp. on the basis of 16S rRNA analysis. The isolate namely, Haloarcula sp. TG1, was found to be 99% identical to Haloarcula salaria strain HST01-2R. The TG1 protease was found to possess very high activity and stability over a broad pH and temperature ranges. Its maximum activity was recorded at pH: 4.0, 50°C and 4 M NaCl. Among inhibitors tested, dimethyl sulfoxide (DMSO) and ethanol caused the highest decrease (ca. 25%) in its activity.

Conclusion

Due to the high activity and stability over a wide range of extreme conditions, Haloarcula sp. TG1 protease reported here is a promising candidate in biotechnology.
Telecoupling framework for research on migratory species in the Anthropocene

Migratory species are an important component of biodiversity and provide essential ecosystem services for humans, but many are threatened and endangered. Numerous studies have been conducted on the biology of migratory species, and there is an increased recognition of the major role of human dimensions in conserving migratory species. However, there is a lack of systematic integration of socioeconomic and environmental factors. Because human activities affect migratory species in multiple places, integrating socioeconomic and environmental factors across space is essential, but challenging. The holistic framework of telecoupling (socioeconomic and environmental interactions over distances) has the potential to help meet this challenge because it enables researchers to integrate human and natural interactions across multiple distant places. The use of the telecoupling framework may also lead to new conservation strategies and actions. To demonstrate its potential, we apply the framework to Kirtland’s warblers (Setophaga kirtlandii), a conservation-reliant migratory songbird. Results show accomplishments from long-term research and recovery efforts on the warbler in the context of the telecoupling framework. The results also show 24 research gaps even though the species has been relatively well-studied compared to many other species. An important gap is a lack of systematic studies on feedbacks among breeding, wintering,and stopover sites, as well as other “spillover” systems that may affect and be affected by migration (e.g., via tourism, land use, or climate change). The framework integrated scattered information and provided useful insights about new research topics and flow-centered management approaches that encapsulate the full annual cycle of migration. We also illustrate the similarities and differences between Kirtland’s warblers and several other migratory species, indicating the applicability of the telecoupling framework to understanding and managing common complexities associated with migratory species in a globalizing world.
#LaughingWhileBlack
Authors: Monk-Payton Brandy
Published: March 2017

This article examines humor as it intersects with race and gender in digital media. It takes up the idea of laughter to explore how Black expressive culture emerges online, both individually and collectively, in the contemporary moment, arguing that web-based objects such as blogs and podcasts as well as tweets, hashtags, and memes that exist and circulate on social media produce racialized and gendered humor predicated on ridicule. Such ridicule is tied to a genealogy of Black feminist and Black queer enactments of “sass” and “shade” as affective strategies of social scrutiny. By detailing the humor associated with the popular viral personalities Luvvie Ajayi and Crissle West as well as the social networking platform Twitter, this article begins the work of archiving Black women's daily comedic performances on the Internet.
