The Third Time’s a Charm
Authors: Butts Brittany , Higgins Melinda , Dunbar Sandra , Reilly Carolyn 
Published: May 2017

Background and Objective:
Since first being published in 2009, the Atlanta Heart Failure Knowledge Test (AHFKT) has proven a reliable and valid instrument and has been used in multiple studies. Given advances in heart failure (HF) self-care, we proposed to reevaluate the psychometric properties of the AHFKTv2 across these recent studies and update the instrument.

Methods:
Demographic, clinical, and baseline AHFKTv2 data from 4 intervention studies in persons with HF were combined for this analysis (N = 284). The 30 questions of the AHFKT are focused on 5 HF self-care knowledge domains: pathophysiology, nutrition, behavior, medications, and symptoms. Characteristics of the sample were analyzed using descriptive statistics; validity testing with t tests and Mann-Whitney 2-group tests and Pearson r and Spearman ρ correlations; and reliability calculations and factor analysis were performed based on tetrachoric correlations.

Results:
Participants were 22 to 84 years of age, 66% were African American, 63% were male, and 94% had New York Heart Association class II to III HF. Mean AHFKT score was 80.6% (±11%). Hypotheses that higher levels of knowledge would be associated with higher education level (t = −2.7, P < .01) and less sodium consumption (ρ = −0.22, P = .03) were validated. Factor analysis revealed 1 general knowledge factor with good reliability, Cronbach’s α was .87. Item response analysis identified individual questions requiring review and revision.

Conclusion:
Comprehensive psychometric evaluation of the AHFKTv2 confirmed its internal consistency reliability and validity and provided direction for production of the AHFKTv3 available for use in research and clinical practice.
Deep Neural Networks in Computational Neuroscience
Authors: Kietzmann Tim C , McClure Patrick , Kriegeskorte Nikolaus 
Published: May 2017

SummaryThe goal of computational neuroscience is to find mechanistic explanations of how the nervous system processes information to give rise to cognitive function and behaviour. At the heart of the field are its models, i.e. mathematical and computational descriptions of the system being studied, which map sensory stimuli to neural responses and/or neural to behavioural responses. These models range from simple to complex. Recently, deep neural networks (DNNs) have come to dominate several domains of artificial intelligence (AI). As the term “neural network” suggests, these models are inspired by biological brains. However, current DNNs neglect many details of biological neural networks. These simplifications contribute to their computational efficiency, enabling them to perform complex feats of intelligence, ranging from perceptual (e.g. visual object and auditory speech recognition) to cognitive tasks (e.g. machine translation), and on to motor control (e.g. playing computer games or controlling a robot arm). In addition to their ability to model complex intelligent behaviours, DNNs excel at predicting neural responses to novel sensory stimuli with accuracies well beyond any other currently available model type. DNNs can have millions of parameters, which are required to capture the domain knowledge needed for successful task performance. Contrary to the intuition that this renders them into impenetrable black boxes, the computational properties of the network units are the result of four directly manipulable elements:input statistics, network structure, functional objective, andlearning algorithm. With full access to the activity and connectivity of all units, advanced visualization techniques, and analytic tools to map network representations to neural data, DNNs represent a powerful framework for building task-performing models and will drive substantial insights in computational neuroscience.
Juvenile hormone, but not nutrition or social cues, affects reproductive maturation in solitary alkali bees (Nomia melanderi)
Authors: Kapheim Karen M. , Johnson Makenna M. 
Published: May 2017

AbstractEusocial insect colonies are defined by extreme variation in reproductive activity among castes, but the ancestral conditions from which this variation arose are unknown. Investigating the factors that contribute to variation in reproductive physiology among solitary insects that are closely related to social species can help to fill this gap. We experimentally tested the role of nutrition, juvenile hormone, and social cues on reproductive maturation in solitary alkali bees (Halictidae:Nomia melanderi). We find that alkali bee females emerge from overwintering with small Dufour's glands and small ovaries, containing oocytes in the early stages of development. Oocyte maturation occurs rapidly, and is staggered between the two ovaries. Lab-reared females reached reproductive maturity without access to mates or nesting opportunities, and many had resorbed oocytes. Initial activation of these reproductive structures does not depend on pollen consumption, though dietary protein or lipids may be necessary for long-term reproductive activity. JH is likely to be a limiting factor in alkali bee reproductive activation, as females treated with JH were more likely to develop mature oocytes and Dufour's glands. Unlike for related social bees, the effects of JH were not suppressed by the presence of older, reproductive females. These results provide important insight into the factors that influence reproductive activity in an important native pollinator, and those that may have been particularly important in the evolution of reproductive castes.
Social mobility and Fair Access to the accountancy profession in the UK
Authors: Duff Angus 
Published: May 2017

PurposeThe purpose of this paper is to consider how Big Four and mid-tier accountancy firms in the UK are responding to political concerns about social mobility and Fair Access to the accountancy profession.Design/methodology/approachInterviews were undertaken with 18 public accountancy firms, ranked in the Top 30 by fee income, operating in the UK to identify how they are recruiting staff in the light of the Fair Access to the Professions’ agenda. Bourdieusian sociology is used to inform the findings.FindingsThe Big Four firms employ a discourse of hiring “the brightest and the best” to satisfy perceived client demand, where symbolic capital is instantiated by reputational capital, reflecting prestige and specialisation, supported by a workforce with elite credentials. For mid-tier firms, reputational capital is interpreted as the need for individuals to service a diverse client portfolio. In general, most interviewees demonstrated relatively limited awareness of the issues surrounding the Fair Access agenda.Research limitations/implicationsThe interviews with accountancy firms are both exploratory and cross-sectional. Furthermore, the study was undertaken at an embryonic point (2010) in the emerging Fair Access discourse. Future work considering the accountancy profession could usefully examine if, and how, matters have progressed.Social implicationsThe investigation finds that accountancy firms remain relatively socially exclusive, largely due to the requirement for high educational entry standards, and interviewees’ responses generally indicate only limited attempts at engagement with political agendas of promoting Fair Access to the profession.Originality/valueThis paper is the first to empirically evaluate how the accountancy profession is responding to the Fair Access agenda; documents changing patterns of recruitment in accountancy employment, including the hiring of non-graduates to undertake professional work; and augments the literature considering social class and accounting.
Structure of intellectual capital – an international comparison
Authors: Inkinen Henri , Kianto Aino , Vanhala Mika , Ritala Paavo 
Published: May 2017

Purpose
Academics and practitioners around the world have shown interest in what constitutes the relevant intellectual capital (IC) in firms. However, studies have largely neglected to examine whether IC has identical or different structural elements in various parts of the world. The purpose of this paper is to suggest that country-specific institutional structures may impact the perception of IC, and empirically analyse whether differences exist between five countries drawing on the institutional theory.

Design/methodology/approach
This study tests for the differences in the underlying categorizations of IC in a sample consisting of 708 firms across five countries. Confirmatory factor analysis and comparison of different possible IC models are conducted to empirically examine the IC structure.

Findings
The results demonstrate that IC has predominantly the same underlying elements across the examined countries. However, trust capital in Finland and renewal capital in Serbia are structurally different compared to other countries.

Research limitations/implications
Institutional theory and multinational corporate superculture can explain the similarity in the IC structures across countries. Specifically, globalized markets carry institutionalized rules, norms, and expectations for the participating firms; under the influence of this superculture, the firms begin to assimilate. Conversely, the differences suggest that some country- and culture-specific differences remain even during the transition to global markets.

Originality/value
This study is among the first to question the assumption that IC has identical structural elements across the world, and merges theories of IC and institutions to explain the possible origins of these differences.
The quality of the metacommunication of the interface and search system of the CAPES Portal of e-Journals
Authors: Gomes Gracielle Mendonça Rodrigues , Cendon Beatriz Valadares 
Published: May 2017

PurposeThe study aims to propose the use of the semiotics inspection method (SIM) which is an interpretative and qualitative method from semiotics engineering (SE) for the evaluation of the communicability of systems and to evaluate digital libraries and information retrieval systems (IRS). The paper presents the results of the application of this method in the evaluation of the quality of the communicability of the interface and search system of the Coordination for the Improvement of Higher Education Personnel (CAPES) Portal of e-Journals, a major scientific digital library in Brazil. There are proposed solutions to improve this system included.Design/methodology/approachThe study used the SIM to evaluate the system. Two evaluators inspected the system. They performed the comparison and the analysis of three types of metamessages (metalinguistic, static and dynamic). The metamessages generated by the evaluators were contrasted to find inconsistencies and ambiguities in the CAPES Portal of e-Journals. Finally, the last step of the method was the final assessment about the inspection.FindingsThe evaluators identified 52 problems of communicability. These problems were ranked according to severity ratings established by Nielsen (1994). They were grouped in ten types of problems present in the interface and in the search system of the CAPES Portal of e-Journals.Originality valueThis research contributes theoretically to the field of information retrieval and to the area of human–computer interaction and, in particular, to the theory of SE by adapting SE methods that allow the evaluation of communicability to the context of the scientific IRS. Results obtained through scientific methods should contribute to development of the interface and search tools of IRS to better support query formulation and retrieval of relevant information and more efficiently satisfy the information needs of individuals.
What influences teachers to continue using cloud services?
Authors: Wang Chia-Sui , Jeng Yu-Lin , Huang Yong-Ming 
Published: May 2017

Purpose
The purpose of this study is to explore the determinants of teachers’ continuance intention concerning cloud services.

Design/methodology/approach
This study uses a cloud service, namely, Google Sites, to support teacher collaboration and further develop a research model to explore the determinants of their continued usage intention.

Findings
The findings reveal that continued intention to use the cloud services is primarily determined by their attitude towards using it; attitude towards using is affected by perceived ease of use and perceived usefulness; and perceived ease of use is influenced by facilitating conditions, while perceived usefulness is influenced by social influence.

Practical implications
This study determines that teachers intend to continue using cloud services once training in using such services has been provided and if they hear favourable opinions from others.

Originality/value
The paper enables us to better understand factors affecting teachers' continuance intention toward cloud services.
An assessment of rural libraries and information services for rural development
Authors: Omeluzor Saturday U. , Oyovwe-Tinuoye Gloria O. , Emeka-Ukwu Uche 
Published: May 2017

Purpose
This study aimed to assess the rural libraries and information services for rural development in Delta State, Nigeria.

Design methodology/approach
The study adopted both descriptive and exploratory research designs. Questionnaire, observation and structured interview guide were the major instruments for data collection. Total enumeration was used to gather data from respondents in 16 functional rural libraries in Delta State.

Findings
The study revealed the challenges that surround the rural people in accessing information in rural libraries. It showed that only 16 rural libraries were established and functional in 16 communities within the 25 local government areas. Findings also showed that the rural libraries were not able to fulfil their roles. It was evident that the information needs of the rural people which made them to access the library were not adequately met because of some hindrances such as inadequate up-to-date information materials, lack of awareness, illiteracy, language barrier, inadequate skilled personnel and inadequate infrastructure and facilities.

Practical implications
The important finding in this study is that rural libraries are the most relevant institution to disseminate information about government policies, inculcating reading habits and developing skill and knowledge of people. Therefore, underdevelopment of rural libraries and inadequate information sources and facilities will hinder access to information and development of the people who need them.

Originality value
This research is the first of its kind to assess rural libraries and information services for the development of rural people in the 16 rural libraries in Delta State of Nigeria.
Assessment of global law and psychiatry research in the period of 1993-2012
Authors: Lv Hong 
Published: May 2017

Purpose
The purpose of this paper (bibliometric analysis) is to analyse the global scientific outputs, research patterns, research emphases and trends of law and psychiatry (L&P) research during 1993-2012 from the Web of Science (WOS) database. Besides, the paper also offers an overview to deepen intercultural understanding and cooperation in the field among professionals concerned with the interface of this research field and related disciplines.

Design/methodology/approach
This paper conducted a bibliometric study of the characteristics and patterns of publication outputs, major journals, network of co-occurrence of authors, international productivity and collaboration.

Findings
International Journal of Law and Psychiatry, Journal of the American Academy of Psychiatry and the Law and Psychiatry, Psychology and Law were the representative journals in the field of L&P research. The results from the analysis of co-occurrence of authors suggest that the L&P co-authorship network analysis is relatively fragmented. In addition, the most productive institution was the University of California System, which published the most inter-institutional collaborative publications and was the top institution by centrality measures. The Harvard University published the most single-institute publications. The most productive country was the USA, which was the top country by centrality measures. The USA was the most collaborative country and took the central position in the collaborative network.

Originality/value
This is the first study to quantify and evaluate global research productivity in L&P viewed through the WOS during 1993-2012, which might provide a potential guide for future research among professionals concerned with the interface of L&P, as it is a very constructive contribution to the area.

Russian S&T Foresight 2030: case of nanotechnologies and new materials
Authors: Vishnevskiy Konstantin , Yaroslavtsev Andrei 
Published: May 2017

Purpose
The purpose of this paper is to apply Foresight methodology to the area of nanotechnologies and new materials within the framework of Russian S&T Foresight 2030 aimed at revelation of major trends, most promising products and technologies.

Design/methodology/approach
To achieve this goal, best international practice was analyzed that provided a solid basis for Russian S&T Foresight 2030 (section “Nanotechnology and new materials”). The study used a wide range of advanced Foresight methods adapted to Russian circumstances. During the Foresight study, the authors integrated “market pull” and research “technology push” approaches including both traditional methods (priority-setting, roadmaps, global challenges analysis) and relatively new approaches (horizon scanning, weak signals, wild cards, etc.).

Findings
Using the methods of the Foresight, the authors identified trends with the greatest impact on the sphere of nanotechnology and new materials, promising markets, product groups and potential areas of demand for Russian innovation technologies and developments in this field. The authors assessed the state-of-the-art of the domestic research in the area of nanotechnologies and new materials to identify “white spots”, as well as parity zone and leadership, which can be the basis for integration into international alliances and positioning of Russia as a center of global technological development in this field.

Originality/value
The results of applying Foresight methodology toward revelation of the most prospective S&T areas in the field of nanotechnologies and new materials can be used by a variety of stakeholders including federal and regional authorities, technology platforms and innovation and industrial clusters, leading universities and scientific organizations in formulation of their research and strategic agenda. Russian businesses including both large companies and small and medium-sized enterprises can use results of the study in creating their strategic R&D programs and finding appropriate partners.
Unsteady double-diffusive buoyancy-induced flow in a triangular solar collector shape enclosure with corrugated bottom wall
Authors: Rahman M.M. , Saha Sourav , Mojumder Satyajit , Rabbi Khan Md. , Hasan Hasnah , Ibrahim Talaat A. 
Published: May 2017

Purpose
The purpose of this investigation is to determine the nature of the flow field, temperature distribution and heat and mass transfer in a triangular solar collector enclosure with a corrugated bottom wall in the unsteady condition numerically.

Design/methodology/approach
Non-linear governing partial differential equations (i.e. mass, momentum, energy and concentration equations) are transformed into a system of integral equations by applying the Galerkin weighted residual method. The integration involved in each of these terms is performed using Gauss’ quadrature method. The resulting non-linear algebraic equations are modified by the imposition of boundary conditions. Finally, Newton’s method is used to modify non-linear equations into the linear algebraic equations.

Findings
Both the buoyancy ratio and thermal Rayleigh number play an important role in controlling the mode of heat transfer and mass transfer.

Originality/value
Calculations are performed for various thermal Rayleigh numbers, buoyancy ratios and time periods. For each specific condition, streamline contours, isotherm contours and iso-concentration contours are obtained, and the variation in the overall Nusselt and Sherwood numbers is identified for different parameter combinations.
