Методами дифракции медленных электронов и атомной силовой микроскопии исследовалось изменение морфологии поверхности рекристаллизованной фольги W под воздействием одноосного растяжения в сверхвысоком вакууме. С помощью дифракции медленных электронов установлено, что под влиянием одноосного растяжения на поверхности фольги, состоящей из отдельных блоков доминирующей грани (112), происходит разворот структурных блоков. Анализ топограмм различных областей боковой поверхности разорванного образца, полученных методом атомной силовой микроскопии, позволил связать изменения атомной структуры поверхностных слоев фольги с изменением ее рельефа при механическом воздействии.

The need for monitoring, effective and efficient control and evaluation of water quality in regional waters Surabaya become a demand for population growth, climate change and variability in the current era of urbanization. The traditional method is done by collecting water samples, test and analyze water in the laboratory has been relatively expensive and do not have the ability to capture real-time data, analysis and information delivery fast in making decisions. On the other hand, the rapid spread in the use of mobile phones in developing countries has increased mobile data management applications. A variety of mobile applications has also increased in recent years. This is because mobile phones cheap, easy to use and can transmit multiple types of information including images and GPS data remotely. In this paper, the author describes a data communication system of  water quality resources based on UDP protocol. This system is called ubiquitous mobile sensing consisting of microcontroller Arduino, water quality sensors, and Android smartphones. It has the ability to detect temperature, dissolved oxygen (DO), pH and electrical conductivity (EC) in real time. By using this monitoring system, the data result is expected more accurate, faster and cheaper.
Board structure, D&O insurance and the variability of firm performance
Authors: Wang Yuwei , Chen Chia-wei
Published: February 2017

We examine the relation between the disclosure of Directors’ & Officers’ (D&O) Liability insurance and the variability of firm performance. Our results show D&O insurance is positively correlated with the variability of firm performance. Specifically, the evidence shows a one percent increment in D&O insurance coverage will lead to a 0.31, 30, and 0.0008 percent increase in the variability of corporate performance measured in monthly stock returns, annual accounting returns on assets (ROA), and Tobin’s Q respectively. Therefore, instead of reducing risk, the findings of this paper suggest D&O insurance may actually increase firm risk, which is very different from the essential purpose of implementing this insurance
Role of cloud computing as technology innovation in small and medium enterprises in South Africa
Authors: Twum-Darko Michael , Sibanyoni Jabu Lucky
Published: February 2017

The paper discusses cloud computing as a technology innovation for small and medium enterprises (SMEs) in South Africa to improve competitiveness, retain sustainability and maintain cost-effectively. The concept of duality of structures (DoS) of Giddens’ Structuration Theory was used as a lens through which to understand and interpret the factors influencing the readiness of SMEs to adopt cloud computing as a lens to innovate their businesses and become competitive in the face of global economic slowdown, high cost of IT services and inadequate e-competency. The purpose of the study was to determine the readiness of SMEs to innovate their businesses using technology solutions such as cloud computing. An extensive investigation on sixteen (16) SMEs from Gauteng and Mpumalang Provinces indicated a number of factors suggested by DoS have influenced the readiness of SMEs to adopt technology. The perspective is that clouding computing adoption as a technology innovation suggests a significant trend with the potential to increase agility and lower costs of IT services. The finding of the study is a general framework to guide SMEs to assess their readiness to adopting these technologies to save costs, improve their efficiency and competitive position

Published: February 2017

The main objective of this study is to investigate the extent of public listed companies compliance with the audit committee rules and to examine the association between Indonesian business characteristics and the compliance of public listed companies with the rules. The results indicate that the compliance of public listed companies with the rules is unsatisfactory. In terms of determinants of the compliance, the different types of family control have a different effect on the compliance of public listed companies with the rules. Additionally, public listed companies with politically connected independent commissioner are less likely to comply with the rules. In contrast, public listed companies with large genuine foreign institutional investors are more likely to comply with the rules
Developing a model to evaluate the information technology competence of boards of directors
Authors: Mohamad Shafi , Hendrick Mary , O’Leary Conor , Best Peter
Published: February 2017

IT governance is critical in the current business environment. Boards of directors are ultimately responsible for ensuring the entities they control have appropriate IT facilities. This study develops a model of IT competences boards should have, to achieve appropriate IT governance. The model is then pilot tested, using Ireland as a case study, to evaluate two issues. Firstly, whether these are the appropriate competences current boards need and second, whether boards appear to have those competences. A survey was completed by Chief Information Officers (CIOs) of Irish listed companies. Results indicate the model is an appropriate method with which to evaluate board IT competence, and companies in Ireland appear to be at a satisfactory competence level. The significance of the research is that the model can now be used to evaluate board IT competence in other jurisdictions. Furthermore comparisons of managements’ evaluations and boards’ evaluations can be assessed

Study Design

Historical cohort study.

Background

History of a knee joint injury and increased fat mass are risk factors for joint disease.

Objective

The objective of this study was to examine differences in adiposity, physical activity, and cardiorespiratory fitness between youths with a 3- to 10-year history of sport-related intra-articular knee injury and uninjured controls.

Methods

One hundred young adults (aged 15–26 years; 55% female) with a sport-related intra-articular knee injury sustained 3 to 10 years previously and 100 controls matched for age, sex, and sport, who had no history of intra-articular knee injury, were recruited. Fat mass index (FMI) and abdominal fat (fat mass at the L1 to L4 vertebral levels) were derived using dual-energy X-ray absorptiometry. Physical activity and cardiorespiratory fitness were measured using the Godin Leisure-Time Exercise Questionnaire and the multistage 20-meter shuttle run test for aerobic fitness, respectively.

Results

Previously injured participants demonstrated higher FMI (within-pair difference, 1.05 kg/m2; 95% confidence interval [CI]: 0.53, 1.57) and abdominal fat (461 g; 95% CI: 228, 694) than uninjured controls. In multivariable linear regression analysis, previous injury was significantly associated with increased FMI. This increase was attenuated in those who participated in higher levels of physical activity or had higher estimated maximum volume of oxygen.

Conclusion

As a risk factor for osteoarthritis in an already susceptible group, excess adiposity is an undesirable trait in the potential pathway to joint disease. Increasing physical activity in this population may be a potential intervention to reduce adiposity thus impede disease initiation and/or progression.

L’action collective des adolescents : premiers pas d’entrepreneurs ?
Authors: Maunaye Emmanuelle , Poisson Fransez
Published: February 2017

Cet article s’interroge sur l’impact d’expériences d’entrepreneuriat collectif telles que la coopérative jeunesse de services (CJS) et la junior association (JA) sur des adolescents. La CJS et la JA constituent des lieux d’apprentissages permettant le développement de savoir-faire et de savoir-être. L’apprentissage entrepreneurial collectif y est plus diffus. L’étude menée au sein de ces deux dispositifs montre que si la CJS a une vocation éducative, elle n’accompagne pas particulièrement la poursuite d’activités collectives entre les membres. En revanche, la JA observée a pu se transformer en une association qui agit toujours dans une logique entrepreneuriale fondée sur le bénévolat.
Administration for Implementing Region-Specific Need-Based Programs
Authors: Dorothy J. S.
Published: February 2017

Education worldwide now embraces an array of teaching and learning modes, and heterogeneous clientele with various needs and purposes for seeking knowledge and skills. In India, model Regional Specific Need-based Programs (RSNP) are unique for they cater to the need for immediate certification yield, or for knowledge to be developed through validated curricula. The level of sophistication of the programs is dependent on whether admission of clientele is based on mandatory entrant eligibility criteria or the basis of an Assessment of Prior Learning (APL). Needs of the individual clientele should be at the base of developing the program concept and the zeal of developing a program should prevail until the clientele successfully complete the program, culminating in an appropriate placement. This paper offers a practical description of the complex nature of the administrative frameworks necessary for RSNP to yield fruitful, quantifiable results. This paper also identifies the potential opportunities and threats likely to be encountered in each of the stages of development and implementation of an RSNP including ethical considerations in dealing with such programs in the education sector.

The article is based on the study of nutritional status of girl students attending an Urban College in Kolkata, India. Their nutritional status was evaluated through their food chart, weight and height measurement, their family socio-economic condition and female nutritional condition under disproportionate male female ratio present in the family. The data collection was made through direct interaction and also through questionnaire containing information sheet to learn the regular diet chart of the respondents, number of members in the family and family income. The arrangement for occasional and need based involvement of medical practitioner was made to investigate significant cases of special nature. The overall aim of the research was to set up a cue to the family socio-economic condition and its correlation with women nutritional position. The data collection method was innovative because it was conducted following parallel interaction method through students to students interaction in the class room situation. The data collectors included the girl students from Human Rights Cell, and the respondents included the willing girl students from the basic streams. The method of information gathering was evolved through direct interaction and also through questionnaire. The research aimed at imbibing nutritional awareness along with the nutritional analysis of the students (both the investigators and the investigated) through interaction and through discussion awareness. The awareness part aimed to inform the young women about their nutritional position and the need for their better nutritional condition as the future mothers. The uniqueness of the program includes data collection and information dissemination through peer group interaction. The overall outcome was to reach out to the women students with low cost nutritional chart and awareness against junk food with fitness diet chart prescribed by the medical practitioner. As a Best Practice Measure, the proposed research cum nutritional awareness program aimed to adopt corrective and remedial measure for students` general health.

El debate sobre la corrupción de la opinión pública en la sociedad de masas
Authors: Niño Rodríguez Antonio
Published: February 2017

En las primeras décadas del siglo XX se produce un cambio muy significativo en la percepción del papel que juega la opinión pública en los sistemas políticos representativos. Si en los sistemas liberales la opinión pública se concebía como una instancia crítica de la política, como la voz del pueblo que vigila a sus gobernantes, con la nueva política de masas la opinión se convertía en un objeto de manipulación y en un instrumento de presión política. En este ensayo analizaremos cómo la preocupación por las consecuencias de la política de masas conducirá a una reflexión sobre el papel de la opinión pública en los regímenes democráticos, y cómo se desarrolló, ya en el periodo de entreguerras, un conocimiento experto sobre la manera de medir y orientar esa opinión en beneficio de los intereses superiores del Estado.

Authors: Nunes Junior Paulo Cezar , Batista Janir Coutinho , Belleze Gabriela
Published: February 2017

O artigo tem por foco central a discussão do conceito de mediação cultural a partir das experiências advindas com a realização do projeto de extensão universitária intitulado FICA – Festival Integrado de Cultura e Arte. Realizado desde 2011 e com oferta de programação na área de música, dança teatro, artes visuais, performances e oficinas de formação, tal projeto tem por objetivo promover estratégias de democratização cultural e mobilização social, e abrange atualmente nove cidades sul-mineiras. A partir das iniciativas realizadas pela Coordenação de Mediação Cultural dentro das últimas três edições do festival, observou-se maior engajamento por parte da equipe de trabalho envolvida e público participante, corroborando para apropriações mais significativas da atividades desenvolvidas no festival, sobretudo no que diz respeito ao caráter relacional existente entre intermediadores culturais, públicos expectadores e artistas participantes. Em paralelo a este debate, a artigo resgata ainda a forma pela qual o conceito da mediação cultural vem sendo tratado pelos pesquisadores da área, e estabelece diálogos com as teorias de Gilles Deleuze, Félix Guatari, Walter Benjamin e Gilbert Simondon.

Published: February 2017

Resumo: O objetivo do estudo foi analisar os óbitos fetais entre municípios da nona regional de saúde do Paraná. Pesquisa descritiva com abordagem quantitativa. A coleta aconteceu no primeiro semestre de 2015, no Sistema de Informação de Nascidos Vivos, no Sistema de Informação sobre Mortalidade e nos relatórios do Comitê de Mortalidade Materno e Infantil da nona Regional de Saúde do Paraná. Cinco municípios tiveram aumento nos óbitos fetais entre 2010 e 2013, sendo que, Itaipulândia apresentou os piores índices e Santa Terezinha de Itaipu um aumento de cinco vezes. Entre os óbitos fetais, destacaram-se fetos do sexo masculino, com peso entre 500 e 1499 gramas e idade gestacional de 28 a 36 semanas. Quanto à idade materna, predominou a faixa etária de 20 a 39 anos. Em 2010, a maior parte dos óbitos fetais acorreu com mães de baixa escolaridade, já em 2013, não se observou esta relação. Para a maioria, o tipo de parto foi vaginal, mas ainda se observa que o parto cirúrgico aconteceu em muitos casos de óbito fetal. A construção de estudos sobre a saúde fetal com diferentes enfoques de abordagem torna-se relevante, pois estes têm sido pouco explorados, apesar de sua incontestável importância em termos de saúde pública como indicador da qualidade da assistência pré-natal e ao parto.
Visibilizando os sujeitos históricos: Movimento negro, a intelectualidade acadêmica e a emergência da Lei n. 10.639/03
Authors: Santos Amauri Júnior Silva
Published: February 2017

Os estudos pós-coloniais se constituem como um campo de investigação em que novos pilares epistemológicos e teóricos são pensados, a fim de construírem uma lógica outra para produção de saberes. Segundo Spivak (2010) os estudos pós-coloniais buscam alternativas para a desconstrução da antinomia Oeste/Leste e, com isso, intentam produzir outras formas de pensamento e de modos de vida que “deem voz” aos povos historicamente silenciados pela modernidade/colonialidade. É a partir deste enunciado que o presente artigo procura debater as narrativas historiográficas sobre a participação do sujeito negro na construção da história nacional, bem como frisar a política de silenciamento historiográfico que ocultou a representação e o protagonismo feminino na luta abolicionista. As senhoras abolicionistas, como ficaram conhecidas, escreveram e organizaram: jornais, clubes e sociedades abolicionistas exclusivamente femininos e mistos, bem com, libertaram escravos e atuaram em movimentos sociais e políticos, como nos lembra Silva e Barreto (2014), todavia a historiografia oficializada tratou de silenciar essas vozes, asseverando mais uma vez a dominância de paradigmas exclusivamente baseados em epistemologias eurocêntricas produzidas por pessoas do sexo masculino, ocidentais, cisgêneras, brancas, heterossexuais, urbanas, de classe média. Essas considerações são decisivas para pensarmos em uma história que vai na contramão do que está posto nas narrativas históricas colonialistas. Principalmente se partirmos da premissa que a escrita da história do Brasil privilegiou desde a sua oficialização, com a fundação do IHGB, uma narrativa colonial que desenhou as fronteiras que fixaram os espaços e os papéis dos sujeitos coloniais para construção do Brasil. Os discursos dos historiadores procuravam construir a nação anulando as diferenças e os sujeitos sociais, a fim de trazer coesão a essa “comunidade imaginada”. (Benedict Anderson, 2008).
Measuring Tangrams on a Geoboard
Authors: Bell Carol J.
Published: February 2017

many of us are familiar with the tangram and the geoboard. A tangram is a dissection puzzle consisting of seven flat shapes. One objective of the puzzle is to form a specified shape using all seven pieces, with no pieces overlapping. Geoboards are generally used to explore basic concepts found in plane geometry, such as perimeter and area, or basic shapes, such as polygons. Using tangrams in combination with a geoboard provides a rich activity for students that will help them further develop their skills and understanding of operations and algebraic thinking, number and operations, measurement, and geometry, also mentioned in the Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010).
Thermochromic Fluorescence from B18H20(NC5H5)2: An Inorganic–Organic Composite Luminescent Compound with an Unusual Molecular Geometry

B18H20(NC5H5)2 is a rare example of two conjoined boron hydride subclusters of nido and arachno geometrical character. At room temperature, solutions of B18H20(NC5H5)2 emit a 690 nm fluorescence. In the solid state, this emission is shifted to 620 nm and intensifies due to restriction of the rotation of the pyridine ligands. In addition, there is a thermochromicity to the fluorescence of B18H20(NC5H5)2. Cooling to 8 K engenders a further shift in the emission wavelength to 585 nm and a twofold increase in intensity. Immobilization in a polystyrene thin‐film matrix results in an efficient absorption of pumping excitation energy at 414 nm and a 609 nm photostable fluorescence. Such fluorescence from polystyrene thin films containing B18H20(NC5H5)2 can also be stimulated by emission from the highly fluorescent borane anti‐B18H22 via energy transfer mechanisms. Polystyrene thin‐film membranes doped with 1:1 mixtures of anti‐B18H22 and B18H20(NC5H5)2 thus emit a 609 nm fluorescence and absorb light across more than 300 nm (250–550 nm); this is a significant spectral coverage possibly useful for luminescent solar concentrators. B18H20(NC5H5)2 is fully structurally characterized using NMR spectroscopy, mass spectrometry, and single‐crystal X‐ray diffraction analysis, and its ground‐state and excited‐state photophysics are investigated with UV–vis spectroscopy and quantum‐chemistry computational methods.
Workers’ compensation claims not reported in the Survey of Occupational Injuries and Illnesses: Injury and claim characteristics
Authors: Wuellner Sara E. , Adams Darrin A. , Bonauto David K.
Published: February 2017

Background

Underreporting in the nation's primary source of non‐fatal occupational injury and illness data are well documented, but worker‐level characteristics of unreported cases have not been fully explored.

Methods

Bureau of Labor Statistics’ Survey of Occupational Injuries and Illnesses (SOII) data were linked to Washington workers’ compensation claims to identify injury and claim characteristics associated with unreported cases. Workers’ compensation administrative date data were used to characterize timing of disability and SOII case eligibility.

Results

Based on claim date data, one in five lost time claims with an injury date in the survey year were likely ineligible for SOII case reporting during the survey year. Among SOII‐eligible claims, those involving sprains or strains, employer protests, and those not eligible for work disability payments until months after the initial injury were least likely to be reported in SOII.

Conclusions

SOII case capture is limited both by its cross sectional survey design and employer underreporting. Am. J. Ind. Med. 60:264–275, 2017. © 2017 Wiley Periodicals, Inc.

Published: February 2017

Background

Silicosis is a progressive lung disease resulting from the inhalation of respirable crystalline silica. Lung transplantation is the only treatment for end‐stage silicosis. The aim of this study was to analyze the survival experience following lung transplantation among patients with silicosis.

Methods

We reviewed data for all patients who underwent lung transplantation for silicosis and a matched group undergoing lung transplantation for idiopathic pulmonary fibrosis (IPF) at a single medical center between March 2006 and the end of December 2013. Survival was followed through 2015.

Results

A total of 17 lung transplantations were performed for silicosis among 342 lung transplantations (4.9%) during the study period. We observed non‐statistically significant survival advantage (hazard ratio 0.6; 95%CI 0.24–1.55) for those undergoing lung transplantation for silicosis relative to IPF patients undergoing lung transplantation during the same period.

Conclusions

Within the limits of a small sample, survival in silicosis patients following lung transplantation was not reduced compared to IPF. Am. J. Ind. Med. 60:248–254, 2017. © 2017 Wiley Periodicals, Inc.
A framework for the classification of joint hypermobility and related conditions
Authors: Castori Marco , Tinkle Brad , Levy Howard , Grahame Rodney , Malfait Fransiska , Hakim Alan
Published: February 2017

In the last decade, growing attention has been placed on joint hypermobility and related disorders. The new nosology for Ehlers–Danlos syndrome (EDS), the best‐known and probably the most common of the disorders featuring joint hypermobility, identifies more than 20 different types of EDS, and highlights the need for a single set of criteria to substitute the previous ones for the overlapping EDS hypermobility type and joint hypermobility syndrome. Joint hypermobility is a feature commonly encountered in many other disorders, both genetic and acquired, and this finding is attracting the attention of an increasing number of medical and non‐medical disciplines. In this paper, the terminology of joint hypermobility and related disorders is summarized. Different types of joint hypermobility, its secondary musculoskeletal manifestations and a simplified categorization of genetic syndromes featuring joint hypermobility are presented. The concept of a spectrum of pathogenetically related manifestations of joint hypermobility intersecting the categories of pleiotropic syndromes with joint hypermobility is introduced. A group of hypermobility spectrum disorders is proposed as diagnostic labels for patients with symptomatic joint hypermobility but not corresponding to any other syndromes with joint hypermobility. © 2017 Wiley Periodicals, Inc.
The path to ultrasound proficiency: A systematic review of ultrasound education and training programmes for junior medical practitioners
Authors: Dickson Robert , Duncanson Kerith , Shepherd Shamus
Published: February 2017

Background

Point‐of‐care ultrasound (POCUS) is a form of diagnostic ultrasonography, which has a defined role as a clinical adjunct in patient assessment and management. If it is to continue to develop as a core clinical skill, junior medical practitioners and trainees may benefit from dedicated ultrasound education and familiarisation early in their training. Controversy endures, however, as inappropriate use of this highly technical and operator‐dependent imaging modality has negative clinical implications.

Aims

A systematic review was performed to assess the ability of doctors in training to perform clinically appropriate and beneficial diagnostic ultrasound after undergoing a formal training programme.

Methods

Studies meeting pre‐defined inclusion criteria were identified in electronic databases MEDLINE, EMBASE, CINAHL, PUBMED and through Google Scholar. Methodological quality was assessed using an established series of indicators.

Results

Fifteen studies were included in the review. Ten of these were performed in the United States, and eight focused on emergency medicine trainees. After the teaching intervention, ten studies assessed overall ultrasound capacity by calculating the collective sensitivity and specificity of trainee‐performed ultrasound. Five studies used a standardised objective assessment tool to evaluate ultrasound skills and technique. Studies varied in terms of the specific ultrasound use investigated, teaching programmes used and methodological quality. Consistently identified areas for further research included the definition of the trainee learning curve and what constitutes competency in ultrasound.

Conclusions

Ultrasound can feasibly be incorporated into junior medical practitioner training, but more research is required to assess its effectiveness and appropriateness.

Published: February 2017

The cellular environment of proteins differs considerably from in vitro conditions under which most studies of protein structures are carried out. Therefore, there is a growing interest in determining dynamics and structures of proteins in the cell. A key factor for in‐cell distance measurements by the double electron–electron resonance (DEER) method in proteins is the nature of the used spin label. Here we present a newly designed GdIII spin label, a thiol‐specific DOTA‐derivative (DO3MA‐3BrPy), which features chemical stability and kinetic inertness, high efficiency in protein labelling, a short rigid tether, as well as favorable spectroscopic properties, all are particularly suitable for in‐cell distance measurements by the DEER method carried out at W‐band frequencies. The high performance of DO3MA‐3BrPy‐GdIII is demonstrated on doubly labelled ubiquitin D39C/E64C, both in vitro and in HeLa cells. High‐quality DEER data could be obtained in HeLa cells up to 12 h after protein delivery at in‐cell protein concentrations as low as 5–10 μm.

Published: February 2017

Im Zuge von Sanierungsarbeiten in Kirchenräumen kommt es oft zu Veränderungen der raumakustischen Qualität dieser Räume und leider auch zu Verschlechterungen der Raumakustik. Eine solche subjektiv als Verschlechterung empfundene Veränderung wurde nach Abschluss der (nicht akustisch beratenen) Sanierungsarbeiten im Jahr 2014 auch bei der Stadtkirche St. Michael zu Jena durch die Kirchengemeinde festgestellt. Aus diesem Grund wurden im Anschluss an die Sanierungsarbeiten auf Initiative der Kirchengemeinde 2015 im Rahmen einer Masterarbeit im Studiengang „Bauphysik und energetische Gebäudeoptimierung” an der Bauhaus‐Universität Weimar Untersuchungen zu einem Konzept zur Verbesserung der raumakustischen Qualität des Kircheninnenraumes für Musikdarbietungen erarbeitet. Für die Masterarbeit wurden neben Analysen des raumakustischen Zustandes vor und nach der Sanierung auf Basis von Tonaufnahmen detaillierte raumakustische Messungen zur objektiven Beurteilung des raumakustischen Zustandes nach der Sanierung durchgeführt sowie die Anwendbarkeit eines statistischen Rechenmodells zur Erarbeitung möglicher Verbesserungsmaßnahmen überprüft. Nachdem der subjektive Eindruck der Gemeindemitglieder mit Hilfe der durchgeführten Analysen und Messungen grundsätzlich bestätigt werden konnte, wurden zum Abschluss der Arbeit prinzipielle raumakustische Verbesserungsmaßnahmen als Grundlage für eine nachfolgende detaillierte Auslegung erarbeitet.

Role of Layered Double Hydroxide in Improving the Stability of Aerobic Granular Sludge
Authors: Sun Haoyuan , Chen Shanping , Liu Jianyong , Qian Guangren , Song Lijie
Published: February 2017

Activated carbon (AC), layered double hydroxide (LDH), and metal ions (MIs) were added to aerobic sequencing batch reactors (SBRs), respectively, to improve the stability of aerobic granular sludge (AGS). The results showed that the addition of AC, LDH, and MIs accelerated the sludge granulation. With the addition of LDH, the AGS was denser and more compact, and the protein and polysaccharide contents of the extracellular polymeric substance (EPS) extracted from AGS were higher. In addition, the removal efficiencies of COD and NH4+‐N in the reactor with LDH addition were higher than those with AC and MIs addition, respectively. These results indicate that the AGS cultivated with LDH addition was more stable and more efficient than those with the addition of AC and MIs. The stimulated EPS secretion, the bridging effect and the binding effect played important roles in improving the AGS stability.
Gender Makes a Difference: Investigating Consumer Purchasing Behavior and Attitudes Toward Corporate Social Responsibility Policies
Authors: Jones Raymond J. , Reilly Timothy M. , Cox Marcus Z. , Cole Brooklyn M.
Published: February 2017

The balance between profit maximization and corporate social responsibility (CSR) has become a strategic issue of considerable importance. A key factor in understanding this relationship is identifying consumer reactions to engaging in CSR. Prior literature suggests a gap between consumers' environmental attitudes and behaviors. This study examines this relationship and finds evidence that gender significantly influences this gap between attitudes and behaviors. Specifically, we find that for female segments of the consumer population, this gap is greatly reduced. We use social identity theory to explain this phenomenon of gender differences as they relate to CSR. Along with providing insight to CSR at the individual level with attitudes and behaviors, our findings also have implications at the firm‐ level for how organizations choose and strategically signal their CSR strategies toward specific consumer segments.

Analysis of outage probability for in‐band device‐to‐device communications underlaying cellular network
Authors: Ghavami Hossein , Shirvani Moghaddam Shahriar
Published: February 2017

One of the key strategies for jointly increasing throughput and optimum resource allocation in 5G is device‐to‐device (D2D) communications, which can be obtained by minimizing the outage probability considered as an objective function of optimization problem. To minimize this objective function, we found that outage probability should be modeled by jointly considering the effect of interference, noise, and multipath phenomena. In this paper, the exact formulas for outage probability of in‐band D2D communications underlying cellular network are proposed. In the proposed model, additive white Gaussian noise and Rayleigh multipath fading are considered into 2 radio resource reuse scenarios. In the first scenario, each D2D pair is allowed to reuse radio resource block of one cellular user, whereas in the second scenario, 2 resources of 2 cellular users can be reused. The proposed formulas are compared to the approximate (nonexact) ones, which models additive white Gaussian noise by a constant variance. The numerical analysis for the first and second scenarios show that the approximate formulas and respected exact ones are in accordance with simulation results in MATLAB. Moreover, based on nonorthogonal multiple access approach, 2 approximations for the nonexact and the proposed formulas are extracted, which are acceptable for multiple resource reuse scenario. As a remarkable result, simulation results show that when the distance of the D2D pair from the respected cellular user is more than 71 m (2 times greater than average distance between the D2D nodes), multiple‐reuse scenarios offer higher throughput compared to 1‐reuse scenario in an acceptable outage probability.
Subarctic‐breeding passerines exhibit phenological resilience to extreme spring conditions

Published: February 2017

There has been relatively little study of the capacity of subarctic passerines to adjust their phenologies to rapid changes on their breeding grounds. Here, we assess variation in passerine arrival timing in Denali National Park, Alaska, from 1995 to 2015, a period that included both the warmest and coldest recorded mean spring temperatures for the park. Using an open‐population occupancy modeling approach in which arrival events are random variables, we investigated interannual variation in the arrival distribution for 10 Nearctic–Nearctic migrants, three Nearctic–Neotropical migrants, and one Palearctic migrant. Neotropical–Nearctic migrants varied in terms of the flexibility of their arrival timing, but generally showed plastic phenologies, suggesting resilience under extreme spring conditions. In comparison, Nearctic–Nearctic migrants showed similar or greater plasticity in arrival timing. A majority of species showed synchronous–asynchronous fluctuation in arrival (i.e., synchronous arrival in some years, asynchronous in others) in combination with various levels of the mean response (i.e., early, average, and late arrival), suggesting the presence of interactions between environmental conditions at multiple scales and inter‐individual variation. The presence of synchronous–asynchronous fluctuation in arrival suggests that weakening of the north–south temperature gradient under continued Arctic amplification may strongly affect arrival variances. Our results also suggest that complex interactions between distributional and phenological changes may be possible. For example, the arrival distribution of Fox Sparrow (Passerella iliaca) became more synchronized over time, a pattern that coincided with a dramatic increase in occupancy probability through expansion of its elevational distribution. Overall, our findings suggest that monitoring of the mean–variance relationship may lead to a deeper understanding of the factors shaping phenological responses.
