A library’s information retrieval system (In)effectiveness: case study
Authors: Marijan Robert , Leskovar Robert 
Published: September 2015

Purpose– The purpose of this paper is to evaluate the effectiveness of the information retrieval component of a daily newspaper publisher’s integrated library system (ILS) in comparison with the open source alternatives and observe the impact of the scale of metadata, generated daily by library administrators, on retrieved result sets.Design/methodology/approach– In Experiment 1, the authors compared the result sets of the information retrieval system (IRS) component of the publisher’s current ILS and the result sets of proposed ones with human-assessed relevance judgment set. In Experiment 2, the authors compared the performance of proposed IRS components with the publisher’s current production IRS, using result sets of current IRS classified as relevant. Both experiments were conducted using standard information retrieval (IR) evaluation methods: precision, recall, precision atk,F-measure, mean average precision and 11-point interpolated average precision.Findings– Results showed that: first, in Experiment 1, the publisher’s current production ILS ranked last of all participating IRSs when compared to a relevance document set classified by the senior library administrator; and second, in Experiment 2, the tested IR components’ request handlers that used only automatically generated metadata performed slightly better than request handlers that used all of the metadata fields. Therefore, regarding the effectiveness of IR, the daily human effort of generating the publisher’s current set of metadata attributes is unjustified.Research limitations/implications– The experiments’ collections contained Slovene language with large number of variations of the forms of nouns, verbs and adjectives. The results could be different if the experiments’ collections contained languages with different grammatical properties.Practical implications– The authors have confirmed, using standard IR methods, that the IR component used in the publisher’s current ILS, could be adequately replaced with an open source component. Based on the research, the publisher could incorporate the suggested open source IR components in practice. In the research, the authors have described the methods that can be used by libraries for evaluating the effectiveness of the IR of their ILSs.Originality/value– The paper provides a framework for the evaluation of an ILS’s IR effectiveness for libraries. Based on the evaluation results, the libraries could replace the IR components if their current information system setup allows it.
Mutual value creation in component co-branding relationships
Authors: Cassia Fabio , Magno Francesca , Ugolini Marta 
Published: September 2015

Purpose
– This paper explores the process of mutual value creation in a component co-branding relationship between an unknown component supplier and a well-known Original Equipment Manufacturer (OEM). In particular, the purpose of this paper is to investigate the antecedents of parties’ willingness to engage in mutual value creation, thus enriching Grönroos and Helle’s (2010, 2012) model of mutual value creation.

Design/methodology/approach
– An in-depth longitudinal analysis of a single case study in the cycling wear industry is presented based on data gathered from several sources, including long interviews with managers of a component supplier and an OEM, promotional materials, press releases and articles in cycling-related publications and on web portals, and online conversations among amateur cyclists.

Findings
– Four antecedents of the willingness to engage in mutual value creation are identified: mutual trust; the perceived easiness of alignment between the supplier’s and OEM’s processes and resources relevant to value creation; the expected creation of a substantial level of additional mutual value; and the expected value gains for each party.

Research limitations/implications
– The study analyses only one case in a single industry and adopts a dyadic perspective.

Practical implications
– This study suggests that – contrary to the traditional view – when specific antecedents for mutual value creation are present, the component co-branding strategy is available to many innovative small- and medium-sized firms without strong brands.

Originality/value
– Beyond enriching Grönroos and Helle’s (2010, 2012) model, this study explains why co-branding relationships can be established even in the absence of a strong component brand.
The impact of government support programs for the development of businesses in Chile
Authors: Cancino Christian A. , Bonilla Claudio A. , Vergara Marcos 
Published: September 2015

Purpose– The purpose of this paper is to analyze the impact on businesses in Chile of the Seed Capital Program (SCP) implemented by Chile’s Technical Cooperation Services.Design/methodology/approach– In order to analyze the impact of this SCP, a counter-factual scenario was used that entailed a combination of the propensity score matching with difference in difference methods. A total of 682 businesses were surveyed (378 in the treatment group and the rest in the control group), 164 of which gave complete responses to the surveys, 89 belonging to the treatment group and 75 to the control group.Findings– The results are mixed. On the one hand, the impact of sales is positive but its statistical significance depends on the model used. With regard to the number of employees, however, the results are positive and statistically significant regardless of the model used. The results also show that participating in the program has no incidence on the probability of later obtaining financing.Research limitations/implications– This study highlights the importance of differentiating between opportunity-driven entrepreneurship programs and necessity-driven entrepreneurship programs.Practical implications– It also suggests improvements in public policy to develop entrepreneurship in small businesses in Chile. These suggestions may also be interesting for other countries facing similar challenges in terms of developing private entrepreneurship as a vehicle to generate economic development.Originality/value– This exploratory work may be interesting to those in charge of designing, implementing and evaluating public programs in support of small- and mid-sized enterprise development.
Can emotional differences be a strength? Affective diversity and managerial decision performance
Authors: Kouamé Saouré , Oliver David , Poisson-de-Haro Serge 
Published: September 2015

Purpose– The purpose of this paper is to extend earlier findings suggesting that affective diversity is always negative for group performance, by examining its influence on managerial decision performance in a more controlled environment.Design/methodology/approach– In an attempt to mitigate some of the many methodological challenges associated with studies in “real-word” contexts, the authors chose to adopt a quasi-experimental research design involving teams of master of business administration students engaged in managerial decision making. This research design is consistent with previous research conducted in the area of affect and individual or group-level outcomes.Findings– The results indicate that both positive and negative affective diversity are positively associated with managerial decision performance, although only the relationship with negative affective diversity is significant. Overall, these findings support the idea that affective diversity may constitute a strength in the context of managerial decision making. These results contrast with the findings of previous studies.Research limitations/implications– Further quantitative and qualitative investigation is recommended in order to clarify the contradictory results between the current study and previous research. Specifically, this investigation might concern the effect of contingency factors such as type of team (i.e. ad hoc vs long term), type of task and team-level self-regulation ability.Originality/value– Since the seminal work of Barsadeet al.(2000), no further studies have attempted to resolve some of the empirical questions emerging from preliminary research on affective diversity. The paper thus provides new insights into the effects of affective diversity.
Stochastic portfolio optimization using efficiency evaluation
Authors: Rotela Junior Paulo , Pamplona Edson de Oliveira , Rocha Luiz Célio Souza , Valerio Victor Eduardo de Mello , Paiva Anderson Paulo 
Published: September 2015

Purpose– The purpose of this paper is to analyze portfolios chosen using an efficiency evaluation that considers risk and uncertainty and optimizes the allocation of invested capital using the Sharpe approach.Design/methodology/approach– The portfolios comprised shares on the Sao Paulo Stock Exchange. A chance-constrained data envelopment analysis stochastic optimization model was used, and return and variance were employed as input and output variables.Findings– The model was shown to be viable. It reduced the search space and considered data randomness.Originality/value– Three portfolios were proposed. The variation of the model’s risk criterion fulfilled the requirements of investors with different attitudes to risk. The model proposed can be used as a support tool for stock investment decisions.
Critical reflections from the millennials on the global action against dementia legacy events
Authors: Newman Kristine , Booi Laura 
Published: September 2015

Purpose
– The purpose of this paper is to share information regarding the Global Action Against Dementia Legacy, to critically reflect on the views of the Canadian Young Leaders of Dementia and to strengthen the impact of their voices in the global discussion surrounding dementia.

Design/methodology/approach
– This offers a critical reflection and review of the innovative intergenerational discussions and solutions offered by younger Canadians – specifically, the Millennial Generation.

Findings
– The paper provides insights about how change and solutions in dementia actions may be established through intergenerational collaboration.

Research limitations/implications
– Researchers are encouraged to make room for the voices of younger, less established generations in both discussions and research related to dementia. The younger generations will provide future direction to the Global Action Against Dementia Legacy so it is time to hear their voice too.

Originality/value
– This paper draws on developments in the Canadian context to highlight the potential of encouraging a less-usual, intergenerational approach to developing engagement, research and solutions in dementia.
Embodied energy of service trading in Hong Kong
Authors: Guo Shan , Shen Geoffrey , Yang Jay , Sun Bingxia , Xue Fan 
Published: September 2015

Purpose
– Energy is a resource of strategic importance for high density cities. International trade reshapes the urban economy and industrial structure of a city, which will indirectly affect energy use. As an international trade hub, Hong Kong relies on the import and export of services. Energy performance in the international trading of these services needs to be properly understood and assessed for Hong Kong’s urban renewal efforts. The paper aims to discuss these issues.

Design/methodology/approach
– This study evaluates Hong Kong’s embodied energy in service trades based on an input-output analysis. The three criteria used for assessment include trading areas, industry sector and trade balance.

Findings
– Analyzed by region, results show that Mainland China and the USA are the two largest sources of embodied energy in imports of services, while Mainland China and Japan are the two largest destinations of exports. In terms of net embodied energy transfer, Hong Kong mainly receives net energy import from Mainland China and the USA and supplies net energy export to Japan, the UK and Taiwan. Among industry sectors, manufacturing services, transport and travel contribute most significantly to the embodied energy in Hong Kong’s imported services, while transport and travel contribute most to the energy embodied in exported services.

Originality/value
– This study identifies the characteristics of energy consumption of service trading and establishes a feasible approach to analyze energy performance of service trade in energy-deficient Hong Kong for the first time. It provides necessary understanding and foundation for developing energy strategies in a service-based, high density urban economy.
Biophilic urbanism: contributions to holistic urban greening for urban renewal
Authors: Reeve Angela Chenoweth , Desha Cheryl , Hargreaves Doug , Hargroves Karlson 
Published: September 2015

Purpose– The purpose of this paper is to consider how biophilic urbanism complements and potentially enhances approaches for the built environment profession to holistically integrate nature into cities. Urban nature – also referred to as urban greening and green infrastructure – has increasingly been considered from many perspectives to address challenges such as population pressures, climate change and resource shortages. Within this context, the authors highlight how “biophilic urbanism” complements and may enhance approaches and efforts for urban greening.Design/methodology/approach– The paper provides a review of existing literature in “urban nature” to clarify and discuss the concept of biophilic urbanism. Drawing on this literature review, the authors present a systematic clustering and scaling of “biophilic elements” that could facilitate responding to twenty-first century challenges.Findings– Biophilic urbanism can be applied at multiple scales in urban environments, through a range of multi-functional features that address the pervasive false dichotomy of urban development and environmental protection. Biophilic urbanism can complement urban greening efforts to enable a holistic approach, which is conducive to comprehensive, intentional and strategic urban greening.Originality/value– This paper situates the emerging concept of biophilic urbanism within existing research from multiple disciplines, providing insight for how this can be applied in practice, particularly to the topical challenge of “urban renewal”.
Reducing floodwater ingress rates through an exterior masonry wall of a domestic building
Authors: Beddoes David W. , Booth Colin 
Published: September 2015

Purpose– Experimental field test apparatus has been used to determine the inter-variability and intra-variability floodwater ingress rates of the masonry wall of a domestic building, before and after preparation with an improved surface treatment procedure. The purpose of this paper is to discuss this issue.Design/methodology/approach– Replicated and repeated simulations of floodwater conditions (600 mm head) outside a building were created, before and after the wall was treated with a combination of mortar admixture and surface impregnation.Findings– Untreated and treated floodwater ingress rates were 4.99 litres/hour (234.99 litres/hour/m2) and 1.74 litres/hour (81.90 litres/hour/m2), respectively, and display high intra-variability before treatment. These preliminary results indicate water penetration through masonry is linked to the initial rate of absorption of brick units and perceivably the workmanship of the bricklayer.Originality/value– Reductions in floodwater penetration from outside a building, by the impregnation and admixture treatments of masonry walls, can be achieved to manageable levels. However, the target for rates of water ingress through permeable masonry of < 10 litres/hour/m2, to accord with values for kitemark products, still needs further work.
Supply chain integration with BIM: a graph-based model
Authors: Papadonikolaki Eleni , Vrijhoef Ruben , Wamelink Hans 
Published: September 2015

Purpose– The purpose of this paper is to propose a methodology to integrate the construction Supply Chain (SC) through the application of Building Information Modeling (BIM) and Supply Chain Management (SCM). It features a renovation case as a proof-of-concept.Design/methodology/approach– After analyzing the relevant gaps in the literature, the research followed a modeling approach. The proposed model merged product-, process- and organizational models in a graph-based model to represent and analyze a BIM-based SCM project.Findings– Presently, the information flows of the construction SC are vague. BIM is an aspiring integrator of information flows for construction. The proposed model for SC integration with BIM, offers an approach to identify the project complexities in relation to organizational structures, roles and interactions and integrate the industry.Practical implications– Currently BIM-enabled SCM is not very widely applied in the industry. However, the authors report the increasing interest of most construction stakeholders to engage in the application of the two, after acknowledging the benefits from the individual approaches. Since this combination is quite rare, the research uses a retrospective real-world case study of a SC project with an imaginary application of BIM.Originality/value– Thus far, there is no formal model to represent the interactions of the SC actors along with BIM. The unique combination of a product and a process model, i.e. BIM, with an organizational model aims at integrating the information flows of the SC. The proposed model aims at analyzing and supporting the BIM-enabled SCM in Architecture Engineering and Construction.
BIM for building refurbishment and maintenance: current status and research directions
Authors: Ilter Deniz , Ergen Esin 
Published: September 2015

Purpose
– The purpose of this paper is to present a strategic overview of the current literature on “Building information modelling (BIM) for Building Refurbishment and Maintenance” to unfold the factors behind the relative underdeveloped state of the field and to contribute to the development of a more cumulative knowledge base by presenting the current status and suggesting future directions for research.

Design/methodology/approach
– A systematic review of the literature has been undertaken by classifying and mapping the literature, identifying the input-output relations, exhibiting the areas focused on by researchers as well as neglected ones and by indicating the trends in research through the years. Both qualitative and quantitative analysis is used in the study to better interpret the existing studies in a holistic perspective.

Findings
– Although the need for BIM in facility management (FM) has been acknowledged by researchers and practitioners, the results highlight that studies related to BIM applications in maintenance and especially refurbishment are relatively recent. However, the trend in published articles shows that the interest is continuously growing. Existing research in this field can be clustered in the following subtopics: (1) building survey and as-built BIM, (2) modelling and managing energy, (3) design assessment, (4) access to and integration of maintenance information and knowledge, and (5) information exchange and interoperability.

Originality/value
– The paper identifies the gaps in the research domain that hinders a widespread adoption of BIM in refurbishment and maintenance stages and introduces roadmaps to surmount the challenges identified in each specific subtopic of the field.
Financial Globalization and Economic Growth in Sub‐Saharan Africa: Evidence from Panel Cointegration Tests
Authors: Egbetunde Tajudeen , Akinlo Anthony Enisan 
Published: September 2015

AbstractThis paper examines the long‐run relationship between financial globalization and economic growth in sub‐Saharan Africa using panel unit root tests, panel cointegration tests and panel multivariate ECM. The study finds that the variables are stationary at first difference — I(1). Also, the results reveal that all the variables are cointegrated, that is, they are related in the long run. The results of the ECT test within the framework of panel multivariate ECM confirm the cointegration tests. The paper concludes that there is a long‐run relationship between financial globalization and economic growth in sub‐Saharan Africa. The paper argues that sub‐Saharan African economies will benefit from the era of financial globalization in the long run in as much as the governments promote and encourage sound macroeconomic policies and strong institutions.
Hétérogénéité des Effets de l'aide sur la Croissance Economique en Afrique Subsaharienne: Évidences Comparatives entre Pays Stables et Pays en Post Conflit
Authors: Mallaye Douzounet , Yogo Urbain Thierry 
Published: September 2015

RésuméLa présente étude fournit l'évidence de l'efficacité de l'aide en faisant usage d'un échantillon de 34 pays d'Afrique sub‐saharienne sur la période 1990–2010. Après prise en compte de l'endogénéité de l'aide, les résultats de l'estimation révèlent que l'aide a un effet positif sur la croissance uniquement lorsque l'estimation est contrôlée du niveau de la gouvernance. La dynamique comparative quant à elle montre que la gouvernance et l'éducation sont les principaux canaux de transmission de l'aide à la croissance en environnement stable. En revanche, en environnement de post conflit, l'aide affecte la croissance via l'investissement en capital public (infrastructure). Enfin, l'approche de décomposition d'Oaxaca‐Blinder montre que l'écart en termes de montants d'aide reçus n'explique pas les différences de croissance observées entre pays stables et pays en situation de post conflit. Sur la base de ces résultats, les implications de politiques économiques sont discutées en conclusion.
How Relevant Is the Capital Asset Pricing Model (CAPM) for Tests of Market Efficiency on the Nigerian Stock Exchange?
Authors: Obrimah Oghenovo A. , Alabi Jacob , Ugo‐Harry Blessing 
Published: September 2015

AbstractWe find an asset pricing model which consists of the market portfolio, the market skewness or co‐skewness factors, and portfolio idiosyncratic volatility factor best explains portfolio risk‐return trade‐offs on the Nigerian Stock Exchange (NSE), indicating this model is appropriate for studies of semi‐strong form efficiency of the Nigerian Stock Market. Our finding that an asset pricing model which consists of the market portfolio alone tends to consistently understate portfolio risk indicates this conventional one‐factor specification of the CAPM is inappropriate for tests of the efficiency of the Nigerian Stock Market. With respect to the effects of non‐synchronous trading of stocks on portfolio risk‐return trade‐offs, while the presence of non‐synchronous trading induces greater diversification benefits for investors, we find it simultaneously results in a higher price for market risk; that is, higher levels of risk aversion. Our findings demonstrate preference for market skewness or co‐skewness can be a risk mitigating response to anticipated adverse effects of changes in the risk of the market portfolio on portfolio returns.
Youth Unemployment Duration and Competing Exit States: What Hides Behind Long Spells of Black Youth Unemployment in South Africa?
Authors: Ismail Zaakirah , Kollamparambil Umakrishnan 
Published: September 2015

AbstractThe paper examines the role of personal characteristics in not only determining the unemployment duration but also the probability of unemployment terminating with transitions into wage‐employment, self‐employment or higher education. Formulated within the survival analysis framework using the Labour Market Entry Survey, this study provides the first empirical evidence on black youth unemployment duration in South Africa. The results of the analysis indicate non‐monotonic duration dependence with other individual, household and locational covariates exerting very different impacts on the state‐specific exit rates from unemployment for both young men and women. The scarring impact evident in negative duration dependence and gender‐specific findings point to the need for more informed policy formulation.
