Perception and Adoption of Change Management in Information Institutions: A Study from Croatia
Authors: Dukić Gordana 
Published: September 2015

AbstractThis paper explores the way in which professional staff employed in information institutions perceive changes and different aspects of change management. The research focuses on Croatian libraries, museums and archives, as public and non-profit organizations. The influence of five background variables (institution, gender, age, level of education, and position) was examined in the analysis. The results show that professionals are only partially satisfied with the changes in their institutions. The type of institution they work in, and the position in the management structure proved to be strong predictors of differences in satisfaction ratings. Factor analysis has revealed three factors: change management mechanisms, impact of change on users and local community, and importance and necessity of change. These factors represent the underlying constructs of the professional staff’s perceptions of change and change management. With respect to the background variables, employees generally have similar attitudes toward the latent factors. They are aware that change is important and that well managed changes improve effectiveness and efficiency. However, from their responses, it is clear that change management is not performed properly. Based on the extracted factors, the survey subjects are classified into four clusters. The study highlights some critical areas of change management in information institutions. Since theory and practice of change management in such organizations have been largely disregarded, the paper contributes to a better understanding of these issues.
School Libraries in South Africa and the Post-2015 Millennium Development Goals (MDGs)
Authors: Fombad Madeleine , Jiyane Glenrose V. 
Published: September 2015

AbstractAlthough 2015 marks the target year for attaining the Millennium Development Goals (MDGs) and the United Nations member states are in the process of defining a global development framework to succeed these goals, the MDGs nevertheless remain a development tool for countries’ wider development planning frameworks. In South Africa, various sectors, institutions and organisations are making efforts to attain these goals. Accordingly, the library and information sector is well placed to contribute towards the realisation of the MDGs, as libraries provide a critical support structure for education, economic development and poverty eradication. As time runs out in terms of meeting the 2015 deadline, this paper seeks to demonstrate that school libraries may be instrumental in influencing the pace and extent of progress needed to realise the MDGs beyond 2015. The research on which this article is based adds to the body of knowledge advocating the importance of libraries in realising the MDGs. It will also generate insights for policymakers on the important role of school library in development.
Ethnographic Ecclesiology and the Challenges of Scholarly Situatedness

Published: September 2015

AbstractThis article reflects on the importance of being aware of one’s own situatedness when carrying out empirical research. The unforeseen outcome of a project in which we studied converting refugees’ encounter with the Evangelical Lutheran Church of Denmark provoked these reflections. The fieldwork was carried out in a particular congregation in Copenhagen that has attracted many asylum seekers, primarily of Muslim background. The empirical work revealed that the scholars, as participant observers, experienced the situation in the congregation quite differently than did the refugees. Initially, the scholars did not recognise conflicts and problems related to ethnicity, gender and class among the various groups of refugees. However, interviews based on the refugees’ documentation of their experiences with and within the congregation allowed different perspectives to be articulated. On one hand, perceptual blind spots inspired reflection on the epistemological deficit that characterised the scholarly habitus. On the other, our theological training did enable us to understand the migrant converts’ specific interpretation of the Christian Gospel. The article concludes that it is important to see informants as collaborators with regard to both scholarly reflexivity and the concrete outcome of research in a shared quest for ecclesiological knowledge.
Non-governmental Organisations and Democracy: An Empirical Analysis
Authors: Masi Tania 
Published: September 2015

AbstractThe United Nations established in 2005 the United Nations Democracy Fund (UNDEF), whose objective is to support projects submitted by national NGOs aimed at increasing government accountability. The purpose of this paper is to investigate the impact of NGOs activity on democracy exploiting the UNDEF database. An empirical analysis based on a propensity score matching (PSM) method is implemented on a sample of 102 developing countries. The findings indicate that the average treatment effect on the treated (ATT) is positive and significant only when countries receive UNDEF-funded NGOs projects for three rounds or more. In this case the Polity IV indicator improves by an average of 1.08 points with respect to the level of 2005.

AbstractIn this study, multilayer graphene (Gr)-reinforced cellulose composites were synthesized by using 1-ethyl-3-methylimidazolium diethylphosphonate ionic liquid. The composites were fabricated via dissolving the cellulose in 1-ethyl-3-methylimidazolium diethylphosphonate and Gr loading at different ratios (0.2, 0.4, and 0.6 wt.%). Both sides of the composites were coated with gold leaf to generate electrodes. The effect of Gr loading on chemical functional groups, crystallographic properties, thermal stability, and morphological and mechanical properties of cellulose film was investigated by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, and tensile test, respectively. Electromechanical behavior of the cellulose composite films reinforced with Gr (0.2, 0.4, and 0.6 wt.%) was investigated under DC excitation voltages of 1, 3, 5 and 7 V. Gr loading of 0.2 wt.% increased maximum tip displacement by 400% when the actuator is excited with 3 V.

Published: September 2015

Abstract
This paper presented a comparative study of speed controller design for inverter fed indirect vector controlled induction motor drive systems with symmetric optimum (SO) and genetic algorithm (GA) based model order reduction (MOR) techniques. GA was used in this paper for a new MOR and optimal time domain tuning of a Proportional Plus Integral (PI) controller. Comparative studies showed that the new model order reduction technique performed better than the conventional symmetric optimum order reduction technique. The performance of this controller was investigated with time domain specifications such as Overshoot, rise time, and settling time using the MATLAB-SIMULINK digital simulation software package. The simulated results showed that the proposed controller was better than that of the conventional PI controller.

Abstract
The present study evaluated for the first time, some strength properties and the chemical compositions of seven hardwood species grown in Northeast Egypt, namely, Acacia saligna, Delonix regia, Erythrina humeana, Ficus elastica, Leucaena leucocephala, Melia azedarach, and Meryta sinclairii. The analysis of variance (ANOVA) results indicated that the effect of wood species on the mechanical properties and chemical compositions was significant (P &lt; 0.01). The parameters used to describe the mechanical properties and chemical compositions of the wood of the seven species differed from one species to another. The cellulose contents of the studied species, except for L. leucocephala (43.2 %), M. azedarach (44.1 %), and M. sinclairii (44.0 %), were found to be lower than those of common hardwood species. The variations in MOR, MOE, Cmax, and tensile strength among the seven species were expected given the differences in wood density and chemical compositions. Except for E. humeana, the other hardwood species studied could be considered to have moderate hardness and are suitable for making floor parquets. Overall, based on the studied mechanical properties, the wood of M. azedarach and M. sinclairii showed good MOR, MOE, and Cmax values, whereas E. humeana wood had the lowest such values. In terms of mechanical properties, the seven hardwood species studied in the present investigation can thus be concluded to have the following order: M. azedarach &gt; M. sinclairii &gt; L. leucocephala &gt; D. regia &gt; F. elastica &gt; A. saligna &gt; E. humeana.

Published: September 2015

Abstract
The present investigation was concerned with the delayed discrete S-shaped software reliability growth model with imperfect debugging. In this paper, we developed a discrete model based on non-homogeneous Poisson process by considering two types of fault removal processes. Optimal release policy was suggested to predict the optimal test run after which the software should be released. The sensitivity analysis was performed on the cost and reliability functions. We used the adaptive neuro fuzzy inference system approach to facilitate the computational results and compared it with the analytical results.

Relationship between sickness presenteeism and awareness and presence or absence of systems for return to work among workers with mental health problems in Japan: an Internet‐based cross‐sectional study: Shotaro Doki, et al. Graduate School of Comprehensive Human Sciences, University of TsukubaObjectiveThe objective of this study was to clarify the relationship between sickness presenteeism and the degree of awareness of company regulations regarding financial compensation for absenteeism.MethodsAn Internet‐based survey of 258 full‐time workers who had more than 28 days of sickness absence due to mental health problems was conducted. Workers were categorized as having either low or high sickness presenteeism, and awareness and presence or absence of systems for return to work and duration of financial compensation were compared between groups.ResultsThe following factors were significantly related to high sickness presenteeism based on logistic regression analyses: working for a private company (odds ratio [OR]=2.57; 95% confidence interval [CI]=1.10−5.99); recognition of a gradual resumption system (OR=3.89, 95% CI=1.02−14.81); and awareness regarding the duration of financial compensation (OR=1.04, 95% CI=1.01−1.07).ConclusionsNo relationship was found between mental sickness presenteeism and presence or absence of systems for return to work in our multivariate analysis; however, a relationship was apparent between sickness presenteeism and characteristics of the workers’ companies. These results are expected to contribute to research involving human resources and occupational health.

Published: September 2015

ABSTRACTThe junction resistance control of conducting networks is a crucial factor for high performance of the network-structured conducting film. Here, we show that silver nanowire (AgNW) networks can be stabilized by using single-walled carbon nanotubes (SWCNTs) which were functionalized with 2-ureido-4[1H]pyrimidinone (UHP) moieties. UHP-modified SWCNTs allowed us to fabricate AgNW suspension containing SWCNTs without adding additional dispersant molecules. The stabilization of AgNW networks was achieved by minimizing the joule heating at the NW-NW junction assisted by in-situ interconnection with the work function modulated SWCNTs. We propose that the electrical transportation pathway was modulated by the SWCNTs through the SWCNT-AgNW junctions, which results in a relatively lower junction resistance than the NW-NW junction in the network film.

Published: September 2015

Esta pesquisa apresenta um panorama da sustentabilidade em sete municípios paraenses, que fazem parte do polo de produção do dendê (Elaeis guineensis Jacq.) na Amazônia oriental. Trata-se de uma área com aproximadamente 46.000 km² que apresenta diferentes padrões de usos da terra, considerada prioritária para a implementação da política nacional dos biocombustíveis por apresentar grandes extensões de terras em condições edafoclimáticas favoráveis. A pesquisa, utilizando o Barômetro da Sustentabilidade ”“ BS, faz uma avaliação ex ante do nível de desenvolvimento dos municípios, analisando dados quantitativos e qualitativos de diferentes fontes a partir de 2010. Foram empregados dezesseis indicadores para o bem-estar humano (social) e nove para o bem-estar ecológico (ambiental), ajustados Ã escala do Barômetro. Os resultados do BS mostraram que os municípios ocupam posições intermediárias e potencialmente insustentáveis, o que reflete a fragilidade socioeconômica e ambiental da região estudada.

Authors: CASTRO RAIFRAN ABIDIMAR DE , CASTRO EDNA MARIA RAMOS DE 
Published: September 2015

A crescente demanda por biocombustíveis e pela bioenergia amplia o debate sobre as monoculturas e sobre a sustentabilidade desse tipo de produção. Nesse sentido, o objetivo deste artigo é apresentar uma análise sobre os aspectos positivos e negativos das monoculturas do eucalipto, da soja e do dendezeiro em três regiões brasileiras e suas interligações com a sustentabilidade. Para isso, realizou-se uma revisão bibliográfica e a abordagem da pesquisa adotada foi Ã qualitativa, com ênfase em análises descritivas e explicativas. Como principal resultado, cita-se a falta de entendimento sobre os aspectos positivos e negativos da implantação dessas monoculturas e seus efeitos sobre a sustentabilidade nas localidades onde são cultivadas e suas repercussões sociais, ambientais e econômicas, o que dificulta a tomada de decisão pelos agentes do Estado, pelos empresários e pelas comunidades envolvidas com as culturas.

Published: September 2015

O Brasil é apontado como o maior usuário mundial de agrotóxicos ”“ embora não seja o maior produtor agrícola mundial. Tais informações estimularam nossa pesquisa sobre a percepção dos consumidores brasileiros quanto aos riscos da presença de agrotóxicos e transgênicos nos alimentos, a partir das lógicas próprias Ã esfera do consumo. A partir da realização de Grupos Focais com 86 informantes, a pesquisa mostrou que tais riscos alimentares são percebidos pelos consumidores como intangíveis ou invisíveis, ainda que possam resultar em contaminações químicas e consequências inesperadas das possíveis substâncias nocivas encontradas nos alimentos. Os resultados mostraram, ainda, que há pouca informação e baixa conscientização geral sobre esses riscos alimentares por parte das famílias brasileiras. Concluímos que, apesar da abundância de informações, o conhecimento dos consumidores sobre os riscos alimentares parece trafegar nas brechas entre a ignorância e o desconhecimento.

Published: September 2015

Background: Fitting implants in osteoporotic patients has traditionally been controversial, and there is little scientific evidence relating osteoporosis to marginal bone loss (MBL). The aims of this study are as follows: 1) to evaluate the possibility of a correlation between osteoporosis, as measured by the mandibular cortical index (MCI), and MBL and 2) to assess how various systemic diseases, periodontitis, and placement of implants in regenerated bone are correlated with MBL and MCI.Methods: This retrospective study examines 212 implants inserted in 67 patients. To take a possible cluster failure into account, an implant for each patient was selected (n = 67 implants). MBL was assessed. Osteoporosis was evaluated using the MCI. Both MBL and MCI were assessed from panoramic radiographs. χ2 test was performed (Haberman post hoc test). Significance was P <0.05.Results: When the total sample implant (N = 212) was evaluated, a significant association was found between the presence of osteoporosis and MCI (P <0.001) and between the presence of diabetes mellitus and MCI (P <0.01). Significant associations were also found between MBL and placement of implants in regenerated sites (P <0.001) and between MBL and a previous history of periodontitis (P <0.05). When the sample is evaluated only in selected implants (one per patient, n = 67), significant differences appear to relate only to the MBL with the placement of implants in regenerated bone sites (P <0.001).Conclusions: Osteoporosis (as evaluated by MCI) does not pose a risk for the development of greater MBL. Parameters adversely affecting the development of increased MBL are a previous history of periodontitis and especially the placement of implants at sites of bone regeneration.

Published: September 2015

Background: Enamel matrix derivatives (EMDs) have been used clinically for more than a decade for the regeneration of periodontal tissues. The aim of the present study is to analyze the effect on cell growth of EMDs in a gel carrier in comparison to EMDs in a liquid carrier. EMDs in a liquid carrier have been shown to adsorb better to bone graft materials.Methods: Primary human osteoblasts and periodontal ligament (PDL) cells were exposed to EMDs in both gel and liquid carriers and compared for their ability to induce cell proliferation and differentiation. Alizarin red staining and real‐time polymerase chain reaction for expression of genes encoding collagen 1, osteocalcin, and runt‐related transcription factor 2, as well as bone morphogenetic protein 2 (BMP2), transforming growth factor (TGF)‐β1, and interleukin (IL)‐1β, were assessed.Results: EMDs in both carriers significantly increased cell proliferation of both osteoblasts and PDL cells in a similar manner. Both formulations also significantly upregulated the expression of genes encoding BMP2 and TGF‐β1 as well as decreased the expression of IL‐1β. EMDs in the liquid carrier further retained similar differentiation potential of both osteoblasts and PDL cells by demonstrating increased collagen and osteocalcin gene expression and significantly higher alizarin red staining.Conclusions: The results from the present study indicate that the new formulation of EMDs in a liquid carrier is equally as potent as EMDs in a gel carrier in inducing osteoblast and PDL activity. Future study combining EMDs in a liquid carrier with bone grafting materials is required to further evaluate its potential for combination therapies.
