http://dx.doi.org/10.5007/1807-0221.2016v13n24p64O câncer de mama gera impactos na qualidade de vida das mulheres. Os efeitos colaterais dos tratamentos convencionais sugerem as terapias alternativas como uma opção complementar. Este estudo descritivo-qualitativo propõe-se a identificarqual a motivação dos pacientes com câncer de mama a buscarem as terapias alternativas. Participaram 33 pacientes com histórico de câncer de mama em acompanhamento ambulatorial no município de Joinville-SC. Os dados foram coletados através de entrevistas semiestruturadas e analisados através da técnica de análise da linguagem. Os achados afirmam que houve uma considerável adesão às terapias. A fitoterapia teve maior prevalência e os fatores motivacionais foram psicobiológicos, psicoespirituais e psicossociais. Identificou-se a pouca atuação do profissional enfermeiro na orientação e motivação ao uso desses recursos. Sendo necessário um maior empoderamento destes profissionais sobre tais práticas que podem oportunizar um cuidado mais integral e uma melhor qualidade de vida, bem como minimizar os riscos da utilização empírica.

Judging Women: Twenty-Five Years Further Toward a Feminist Theory of the State
Authors: Chambers Clare
Published: July 2017

This paper engages with the work of Catharine MacKinnon to consider three ways of understanding the phrase "judging women." First, when is it acceptable or necessary to make judgements about what women do? The paper argues that feminist analysis urges compassion and empathy for women, but also highlights the ways that choices are limited and shaped by patriarchy. Thus we cannot and should not avoid all judgment of women’s—and men’s—choices. Second, when can women engage in the act of judging? It is sometimes claimed that it is anti-feminist to engage in such judgment, and that feminists must above all else avoid being judgmental. The paper rejects this idea and argues instead that feminism should insist on women's right to exercise judgment: women’s voices matter. Third, how are we to judge who counts as a woman? MacKinnon’s work offers profound, sustained, rich analysis of these questions, but does not fully resolve them.

Influence of Individual Characteristics, Organizational Support System and Learning Organizational Practices in Post-program Transfer of Training: A Study on Management Development Programs of Bangladesh Civil Service
Authors: Bhuiyan Md Sanwar Jahan
Published: July 2017

Management development programs of Bangladesh Civil Service are traditionally seen as a piecemeal approach; no linkage is found among program performance, transfer performance and career advancement of trained officials. Moreover, no effective mechanism is found in public organization to assess or monitor the issue of post-program transfer of training. The study employed an in-depth investigation into factors affecting post-program transfer of training. It made a detailed investigation into ultimate effectiveness of management development programs by examining contribution of three sets of influencing factors under individual characteristics, work environment (social and logistic support), and learning organizational practices on post-program transfer of training. The study was conducted on two management development courses like Advanced Course on Administration and Development (ACAD) and Senior Staff Course (SSC) by administering survey on purposively selected 212 graduated participants of both the courses. The findings of the study suggest that the predictors like post-program motivation and self-efficacy to transfer, peer support, learning organizational practices like collaboration and team learning and strategic link of transfer performance with career advancement have direct and positive influence on post-program transfer of training. The findings of the study would guide the policy planner to formulate prudent HRD policy and strategy linking training performance (performance of learning acquisition as well as post program transfer) and career advancement (placement and promotion).
Engineering Professors’ Perspectives on Gender and Assessment of Teamwork
Authors: Beddoes Kacey , Panther Grace
Published: July 2017

Teamwork is an important component of engineering education programs; however, when not facilitated well, it can be a site of gender biases. The aim of this article is to thematically explore what and how engineering professors think about gender in the assessment of teamwork. In 2014 and 2015, semi-structured interviews were conducted with 39 engineering professors in the United States. Interviews covered a wide range of topics, with one section of the interviews devoted to teamwork specifically. For this article, the parts of the interviews about assessment of teamwork are analyzed. It was found that most participants were unaware of the ways in which gender can influence assessment and did not attempt to mitigate biases in self-evaluation, peer-evaluation, or team presentations. Recommendations for best practice are offered.

Aim of study: This paper objective focuses on the contribution of multifunctional natural forest silviculture, incorporating both private and public product managements, to forest and woodland economics.Area of study: Spain and California (USA).Material and methods: This conceptual article has developed a critical revision of the existing literature on the main economic issues for multifunctional natural forest silviculture in the last decades.Main results: Multifunctional natural silviculture has secular roots as a local practice, but as a science of the natural environment applied to the economic management of forest lands it is still in the process of maturation. Timber silviculture remains the central concern of forest economics investment in scientific publications. By contrast, silvicultural modeling of the natural growth of firewood, browse and other non-timber forest products from trees and shrubs receives scant attention in scientific journals. Even rarer are publications on multifunctional natural silviculture for forest and woodland managements, including environmental services geared to people’s active and passive consumption. Under this umbrella, private environmental self-consumption is represented by the amenities enjoyed by private non-industrial landowners. As for environmental public products, the most relevant are carbon, water, mushrooms, recreation, landscape and threatened biodiversity.Research highlights: This paper is a good example for the conceptual research on forestry techniques and economic concepts applied to multifunctional silviculture in Mediterranean areas of Spain and California. The combination of technical knowledge and private and public economic behaviors definitively contributes to the multifunctional management of natural forest systems.

Published: July 2017

Worldwide cooperation between laboratories working with classical swine fever virus (CSFV) requires exchange of virus isolates. For this purpose, shipment of CSFV RNA is a safe alternative to the exchange of infectious material. New techniques using desiccation have been developed to store RNA at room temperature and are reported as effective means of preserving RNA integrity. In this study, we evaluated the stability and integrity of dried CSFV RNA stored at room temperature. First, we determined the stability of CSFV RNA covering CSFV genome regions used typically for the detection of viral RNA in diagnostic samples by reverse transcription-polymerase chain reaction (RT-PCR). To this end, different concentrations of in vitro-transcribed RNAs of the 5’-untranslated region and of the NS5B gene were stored as dried RNA at 4, 20, and 37oC for two months. Aliquots were analyzed every week by CSFV-specific quantitative real-time RT-PCR. Neither the RNA concentration nor the storage temperature did affect CSFV RNA yields at any of the time evaluated until the end of the experiment. Furthermore, it was possible to recover infectious CSFV after transfection of SK-6 cells with dried viral RNA stored at room temperature for one week. The full-length E2 of CSFV was amplified from all the recovered viruses, and nucleotide sequence analysis revealed 100% identity with the corresponding sequence obtained from RNA of the original material. These results show that CSFV RNA stored as dried RNA at room temperature is stable, maintaining its integrity for downstream analyses and applications.
Climatic zoning of chia (Salvia hispanica L.) in Chile using a species distribution model
Authors: Cortés Daniela , Silva Herman , Baginsky Cecilia , Morales Luis
Published: July 2017

Salvia hispanica L., known as chia, is a plant species originally from tropical and subtropical Mesoamerica. It is economically important because its seeds produce omega-3, thus its demand has increased in Chile and internationally. As there is no commercial production in Chile, we investigated the places in the country where this species could be cultivated in order to satisfy at the least the national demand. The aim of the study was to quantify the main climatic requirements of chia and to produce a climatic aptitude map for chia cultivation in Chile. The methodology was based on the Maxent species distribution model. We used 78 georeferenced data points where chia is grown throughout the world, mostly from the GBIF database, along with raster climatic layers from the Worldclim project. We estimated the performance curves of annual precipitation and temperature along with their respective optimal and critical values, in analogy with the Ecocrop method. The maps used two scenarios for crops in different conditions, with and without irrigation. The results indicated that the intermediate depression and coastal edge of mainly the Arica y Parinacota, Tarapacá, Antofagasta and Atacama regions have optimum conditions for irrigated crops, but it would be impossible in rainfed conditions. We conclude that chia’s cultivation niche is reduced due to its tropical climate requirements; however, it can be cultivated under irrigation in northern Chile.

Authors: Wu Maoguo , Zhang Hanyang , Tam Kwok-Leung
Published: July 2017

Securities margin trading is a form of credit trading that is used extensively in mature securities markets. With the rapid development of its securities market, China introduced securities margin trading to its A-share market on 31st March 2010 for the purpose of reducing A-share market volatility. Owing to the fact that the introduction of securities margin trading in 2010 only applied to part of the A-share transaction targets, it can be treated as a natural experiment. This paper uses difference-in-differences analysis to investigate whether the introduction of securities margin trading in 2010 decreased China’s A-share market volatility. By selecting 50 underlying stocks of securities margin trading as a ‘treatment group’ and 50 non-underlying stocks as a ‘control group’, this paper utilizes a panel dataset comprising 100 stocks for the period 31st March 2009 – 31st March 2011. Results indicate that the introduction of securities margin trading in 2010 significantly decreased China’s A-share market volatility. In conclusion, this paper recommends that China reduces the barriers and transaction costs of securities margin trading, extends the supply of underlying stocks for securities lending, and enhances the capital supply of margin trading.

Published: July 2017

The benefit of using WiFi for Internet connection is obvious: cost-effective and powerful. WiFi gives us the flexibility and convenience of not being tied to a fixed location. Nowadays, more and more electronic devices and gadgets, such as mobile phones, cameras, gaming devices, TV and entertainment equipment, are WiFi enabled. WiFi also enables your devices to share files instantly. WiFi broadcasting devices, such as Chromecast, give you extra convenience by allowing you to stream video and audio contents from your mobile phone to your TV using WiFi connection. However, this kind of flexibility and convenience comes with a cost. Sharing files, streaming contents or even accessing the Internet via WiFi means signals are being transmitted and they can be captured by anyone with a computer or mobile phone installed with appropriate software. Therefore, it is important to let WiFi users know their security risks and how to minimize them. Educating WiFi users to reduce the WiFi security risk is one of our on-going missions. Basing on empirically collected data, this paper is report of a comprehensive study on the use of WiFi and WiFi networking and the knowledge of WiFi users of the risks and security issues involved in using WiFi in Hong Kong. Findings of the study highlight the WiFi security knowledge gaps of the users in Hong Kong so that stakeholders can take action to improve Internet security by eliminating the security gaps identified.

Published: July 2017

Attitude to the organizations has been changed over the time. Nowadays by increasing changes in business environments, borders between industries have almost been removed. According to James Moore (1993), organizational activities space is now an ecosystem one in which different businesses from different industries have mutual interactions as well as their survivals extensively depend on each other. These concepts are thoroughly propounded in business ecosystem approach.This paper reviewed different types of making strategic decision by using SMOCS Model was presented by Smida 1995 and showed which consequences and results shall be gained in each type for business ecosystem. It also showed scientific and applicable methods of making strategic decision according to SMOCS Model. So each business ecosystem may choose one of strategic decision making types as per situation and its expectation from the results. The method which applied in this research also authorized us to study a concurrent and simultaneous decision making in three main and important variables (resources, objectives and environmental conditions).Results of this research may help managers to make strategic decision in critical situations and also propose effective and useful offers to make decision. It raises knowledge and awareness level in making decision.

Published: July 2017

The objective of this study is to investigate in depth the factors that can reduce the effect of employee burnout in Egypt. From the literature review, the variables of perception of employee development programs (IV1), time spent on employee development programs (IV2), self-actualization (IV3), and workplace democratization (IV4) were identified. To study these variables on employee burnout, SEKEM, a company in Egypt known for its innovative application of human development initiatives, was selected as a case study from Egypt. A single cross-sectional analysis of the employees of the company was used and data was collected with a questionnaire using a 7-level scale.The results were then analyzed with a principal component analysis, Cronbach’s alpha, and Spearman’s rank correlation.The results confirmed the validity and inter-reliability of the model as well as showed the significant negative relationship between both IV1 & IV3 and between employee burnout. IV2 and IV4 were not found to be significantly related to employee burnout.The significance of the research is that few studies in Egypt are made on the issue of employee burnout, and the study of SEKEM provides a rare insight into the application of such concepts.

Authors: Zhang Cheng , Lu Yulin , Xu Ruiyang , Ye Xiaomei , Shi Yuwei , Lu Ping
Published: July 2017

To enhance the engagement of Civil Engineering students and encourage active learning, a virtual construction site investigation game is developed in the present paper. 3D construction site environment is built based on BIM models and relevant objects common on construction sites are created to enhance the realistic. Navigation and Interactions are developed to enable the students to explore the virtual sites freely and get instant feedbacks. Different modules, such as Questions and Tasks, are developed to exam how well the students master the domain-related knowledge. Unity, a cross-platform game engine, is used as the development platform for this research project. The architecture, mechanism and the implementation are described in detail in this paper. A pedagogical methodology for improving the quality of learning is thus developed by transforming traditional instructional delivery techniques into technology-based active learning. Students’ engagement in the learning process is improved by establishing a contextual connection between ordinary textbook materials and technologies that students use in their daily routines. This new approach enables students to interact, and learn abstract topics in engineering design and construction method. The effectiveness of this active learning method is investigated by the feedback from two groups of students using a questionnaire. The potential benefits of the proposed research are: enhanced understanding of complicated structures; better accessibility to more construction site virtually; more convenient and flexible time for learning practices; and safer site visit with this pre-training tool.

Pilot‐Scale Evaluation of Bicarbonate‐Form Anion Exchange for DOC Removal in Small Systems
Authors: Ness Alysse , Boyer Treavor H.
Published: July 2017

This article highlights results from an ion exchange (IX) pilot‐plant study that evaluated bicarbonate‐form anion exchange resin (AER) with sodium bicarbonate (NaHCO3) regeneration for dissolved organic carbon (DOC) removal. Sodium chloride (NaCl) is the conventional regeneration salt; however, NaHCO3 could be used as an alternative to reduce the environmental impacts associated with NaCl brine disposal. In a comparison of chloride‐form AER and bicarbonate‐form AER, results indicated that chloride‐form AER and bicarbonate‐form AER have a similar affinity for DOC; chloride‐form AER treats more bed volumes before breakthrough than bicarbonate‐form AER; chloride‐form AER is regenerated 10–48% more efficiently with NaCl compared with bicarbonate‐form AER regenerated with NaHCO3; polyacrylic AER is regenerated more efficiently than polystyrene AER using both NaCl and NaHCO3; and the total cost of using NaCl and NaHCO3 is comparable when brine disposal is considered. Results from this study provide guidance for small water systems considering IX treatment.

Authors: Palmés Ferrera Mercedes , Andersson Vila Cassandra Ixena , Barrera Reyes Maria del Carmen , García Gigán Maria del Carmen , Graells Piqué Maria Alba , Gómez Rodríguez Esther
Published: July 2017

Antecedentes: El cáncer de ovario causa más muertes que cualquier otro tipo de cáncer ginecológico. La mayoría de casos se diagnostican en una etapa avanzada de la enfermedad y el tratamiento de elección es generalmente la terapia combinada de quimioterapia intraperitoneal (IP) y endovenosa (EV). A pesar de que esta opción farmacológica ha demostrado alargar la supervivencia, se han reportado múltiples efectos adversos asociados a dicho tratamiento.   
Objetivo: Identificar los efectos adversos y las complicaciones derivadas del  tratamiento con quimioterapia IP+EV en pacientes con carcinoma de ovario avanzado a partir de estadio IIIC, durante el periodo 2007-2015.
Metodología: Se realizó un estudio descriptivo, longitudinal y retrospectivo. Un grupo de 17 mujeres diagnosticadas con cáncer de ovario a partir de estadio III fueron tratadas con quimioterapia IP+EV en el Hospital Clínic de Barcelona durante el periodo 2007-2015.
Resultados: De las 17 pacientes que recibieron tratamiento con quimioterapia IP+EV, sólo 5 (29,41%) finalizaron los 6 ciclos de tratamiento. De forma notable, 12 (70,58%) pacientes no completaron el tratamiento debido a una serie de complicaciones, que fueron frecuentemente asociadas al reservorio IP y a trastornos psicológicos. Los principales efectos adversos reportados fueron astenia, neurotoxicidad y dolor abdominal.
Conclusiones: La mayoría de pacientes interrumpieron la terapia debido a complicaciones relacionadas con el reservorio IP y trastornos psicológicos. Creemos que la enfermera juega un papel importante, no sólo en el manejo de los aspectos técnicos de la terapia, sino también en el soporte emocional a dichas pacientes durante esta etapa.

Les modes de sélection des candidats affectent-ils la représentation parlementaire des minorités d’origine étrangère ? Une analyse des élections législatives allemandes de 2013

À la suite des différentes vagues d’immigration des dernières décennies, l’Allemagne, comme la plupart des sociétés contemporaines, est fortement caractérisée par sa diversité ethnique. Pourtant, on ne trouve que très rarement des députés issus de l’immigration au sein du Bundestag. Cet article analyse un aspect de plus en plus évident au vu de la littérature scientifique, mais qui reste peu traité pour l’instant : la relation entre les différents modes de sélection des candidats et la représentation parlementaire des minorités d’origine étrangère. L’analyse empirique de l’impact des procédures d’investiture des partis politiques allemands sur la diversité ethnique des candidats parlementaires est réalisée à partir des statuts des différents partis ainsi que des procès-verbaux des congrès d’investiture des partis. Les résultats de notre analyse exploratoire indiquent tout d’abord qu’en raison des prescriptions légales, les modes de sélection des différents partis politiques allemands présentent une grande homogénéité. Pourtant, nous pouvons également montrer qu’il existe des divergences inter-partisanes (entre, d’un côté, les deux grands partis et, de l’autre, les trois petits) ainsi qu’intra-partisanes (entre les différents Länder allemands). En ce qui concerne la sélection des candidats d’origine étrangère, le positionnement idéologique du parti semble jouer un grand rôle : ce sont avant tout les partis de gauche qui sélectionnent les candidats issus des minorités ethniques. Néanmoins, au-delà de cet impact du positionnement idéologique des partis, nous pouvons également établir qu’au sein du groupe des partis de gauche, des modes de sélection plus ouverts semblent pouvoir contribuer à une plus grande accessibilité aux listes par des aspirants-candidats issus de l’immigration.
Sequential neuromodulation of Hebbian plasticity offers mechanism for effective reward-based navigation

Spike timing-dependent plasticity (STDP) is under neuromodulatory control, which is correlated with distinct behavioral states. Previously, we reported that dopamine, a reward signal, broadens the time window for synaptic potentiation and modulates the outcome of hippocampal STDP even when applied after the plasticity induction protocol (Brzosko et al., 2015). Here, we demonstrate that sequential neuromodulation of STDP by acetylcholine and dopamine offers an efficacious model of reward-based navigation. Specifically, our experimental data in mouse hippocampal slices show that acetylcholine biases STDP toward synaptic depression, whilst subsequent application of dopamine converts this depression into potentiation. Incorporating this bidirectional neuromodulation-enabled correlational synaptic learning rule into a computational model yields effective navigation toward changing reward locations, as in natural foraging behavior. Thus, temporally sequenced neuromodulation of STDP enables associations to be made between actions and outcomes and also provides a possible mechanism for aligning the time scales of cellular and behavioral learning.

Near‐surface air temperatures close to 0°C were observed in situ over sea ice in the central Arctic during the last three winter seasons. Here we use in situ winter (December–March) temperature observations, such as those from Soviet North Pole drifting stations and ocean buoys, to determine how common Arctic winter warming events are. Observations of winter warming events exist over most of the Arctic Basin. Temperatures exceeding −5°C were observed during >30% of winters from 1954 to 2010 by North Pole drifting stations or ocean buoys. Using the ERA‐Interim record (1979–2016), we show that the North Pole (NP) region typically experiences 10 warming events (T2m > −10°C) per winter, compared with only five in the Pacific Central Arctic (PCA). There is a positive trend in the overall duration of winter warming events for both the NP region (4.25 days/decade) and PCA (1.16 days/decade), due to an increased number of events of longer duration.

A fundamental issue for biomedical applications of graphene is the correlation between its physicochemical properties and cellular uptake mechanism. However, such studies are challenging due to the intrinsic polydispersity of graphene. In this work, a series of water soluble graphene sheets with the same polymer coverage, density of functional groups, and fluorescence intensity but three different sizes and surface charges are produced. The effect of the latter two factors and their combination on the mechanism of cellular uptake and intracellular pathways of these defined nanosheets is investigated via confocal and Raman microscopies. While positively (NH3+) and negatively (OSO3−) charged sheets show an energy dependent uptake, their neutral analogs do not show any significant uptake. The cellular uptake efficacy of positively charged graphene sheets is independent of the size and occurs both through phagocytosis and clathrin‐mediated endocytosis pathways. However, cellular uptake efficacy of graphene sheets with negative surface charge strongly depends on the size of the sheets. They cross the membrane mainly through phagocytosis and sulfate‐receptor‐mediated endocytosis. This study demonstrates that the impact of the size of graphene derivatives on their cellular uptake pathways highly depends on their surface charges and vice versa.

An unexpected superconductivity enhancement is reported in decompressed In2Se3. The onset of superconductivity in In2Se3 occurs at 41.3 GPa with a critical temperature (Tc) of 3.7 K, peaking at 47.1 GPa. The striking observation shows that this layered chalcogenide remains superconducting in decompression down to 10.7 GPa. More surprisingly, the highest Tc that occurs at lower decompression pressures is 8.2 K, a twofold increase in the same crystal structure as in compression. It is found that the evolution of Tc is driven by the pressure‐induced R‐3m to I‐43d structural transition and significant softening of phonons and gentle variation of carrier concentration combined in the pressure quench. The novel decompression‐induced superconductivity enhancement implies that it is possible to maintain pressure‐induced superconductivity at lower or even ambient pressures with better superconducting performance.
Liquid Drops Hurdling Barriers of Various Geometries

Drop manipulation and mobility on a solid surface has received widespread attention. However, how a soft liquid drop interacts with a barrier in the direction of its motion, this question still remains open. This study shows liquid drop hurdling the preconditioned barriers with various geometries displaying superhydrophobic surface. Unlike human being, they cannot anticipate barriers and the only possibility is just head‐on confrontation, by deforming themselves to adapt to the barrier's geometry. This study demonstrates experimentally that both the external factors like barriers' geometry and size and internal factors such as drops' initial motion velocity, volume, surface tension, and dynamic viscosity can affect their hurdling dynamics. The hurdling difficulty is quantified through the time and energy loss. These observations throw insight into the dynamics of liquid drops moving on a solid obstacle‐equipped surface, which may facilitate the potential applications like coating technology and liquid transportation.

Published: July 2017

Over the past few years, hybrid halide perovskites have emerged as a highly promising class of materials for photovoltaic technology, and the power conversion efficiency of perovskite solar cells (PSCs) has accelerated at an unprecedented pace, reaching a record value of over 22%. In the context of PSC research, wide‐bandgap semiconducting metal oxides have been extensively studied because of their exceptional performance for injection and extraction of photo‐generated carriers. In this comprehensive review, we focus on the synthesis and applications of metal oxides as electron and hole transporters in efficient PSCs with both mesoporous and planar architectures. Metal oxides and their doped variants with proper energy band alignment with halide perovskites, in the form of nanostructured layers and compact thin films, can not only assist with charge transport but also improve the stability of PSCs under ambient conditions. Strategies for the implementation of metal oxides with tailored compositions and structures, and for the engineering of their interfaces with perovskites will be critical for the future development and commercialization of PSCs.
