Cloud storage for digital preservation: optimal uses of Amazon S3 and Glacier
Authors: Han Yan 
Published: June 2015

Purpose
– The purpose of this paper is to use cloud storage in digital preservation by analyzing the pricing and data retrieval models. The author recommends strategies to minimize the costs and believes cloud storage is worthy of serious consideration.

Design/methodology/approach
– Few articles have been published to show the uses of cloud storage in libraries. The cost is the main concern. An overview of cloud storage pricing shows a price drop once every one or one-and-a-half years. The author emphasize the data transfer-out costs and demonstrate a case study. Comparisons and analysis of S3 and Glacier have been conducted to show the differences in retrieval and costs.

Findings
– Cloud storage solutions like Glacier can be very attractive for long-term digital preservation if data can be operated within the provider’s same data zone and data transfer-out can be minimized.

Practical implications
– Institutions can benefit from cloud storage by understanding the cost models and data retrieval models. Multiple strategies are suggested to minimize the costs.

Originality/value
– The paper is intended to bridge the gap of uses of cloud storage. Cloud storage pricing especially data transfer-out pricing charts are presented to show the price drops over the past eight years. Costs and analysis of storing and retrieving data in Amazon S3 and Glacier are discussed in details. Comparisons of S3 and Glacier show that Glacier has uniqueness and advantages over other cloud storage solutions. Finally strategies are suggested to minimize the costs of using cloud storage. The analysis shows that cloud storage can be very useful in digital preservation.
Introduction of e-reserves at the De La Salle University – Manila libraries
Authors: Yap Joseph Marmol 
Published: June 2015

Purpose
– In introducing e-reserves as an added service of the De La Salle University (DLSU) libraries, the purpose of this paper is to identify the best practices of handling e-reserves and its legal implications as one of the factors that might affect the introduction, development and implementation of such service.

Design/methodology/approach
– Four universities were considered based from the 2013 Quacquarelli Symonds (QS) university rankings in Asia. Only one academic library was maintaining an e-reserve system. It was consulted to know more about their e-reserve practices.

Findings
– The paper recommends to prepare the relevant e-reserve guidelines before it fully operates. Moreover, the Libraries should also collaborate with the office handling learning management systems so as to decide on how to manage the e-reserves. A needs assessment survey for faculty members is also being prepared so as to solicit responses from the teaching faculty if e-reserves is possible for DLSU to be established.

Originality/value
– The paper attempts to document the existing e-reserve system in Philippine academic libraries.
Is disposition related to momentum in Chinese market?
Authors: Kong Liu Liu , Bai Min , Wang Peiming 
Published: June 2015

Purpose
– The purpose of this paper is to examine whether the framework of Prospect Theory and Mental Accounting proposed by Grinblatt and Han (2005) can be applied to analyzing the relationship between the disposition effect and momentum in the Chinese stock market.

Design/methodology/approach
– The paper applies the methodology proposed by Grinblatt and Han (2005).

Findings
– Using firm-level data, with a sample period from January 1998 to June 2013, the authors find evidence that the momentum effect in the Chinese stock market is not driven by the disposition effect, contradicting the findings of Grinblatt and Han (2005) concerning the US stock market. The discrepancies in the findings between the Chinese and US stock markets are robust and independent of sample periods.

Research limitations/implications
– The findings suggest that Grinblatt and Han’s model may not be applicable to the Chinese stock market. This is possibly because of the regulatory differences between the two stock markets and cross-national variation in investor behavior; in particular, the short-selling prohibition in the Chinese stock market and greater reference point adaptation to unrealized gains/losses among Chinese compared to Americans.

Originality/value
– This study provides evidence of the inapplicability of Grinblatt and Han’s model for the Chinese stock market, and shows the differences in the relationship between disposition effect and momentum between the Chinese and US stock markets.
The selection of popular trading strategies
Authors: Chung Yi-Tsai , Liao Tung Liang , Chiang Yi-Chein 
Published: June 2015

Purpose
– The relative performance of five popular nonzero-investment strategies, including Size, book-to-market ratios, earnings-to-price (E/P) ratios, cash flow-to-price (CF/P) ratios and dividend-to-price ratios, and their corresponding zero-investment strategies (also known as premiums) are first examined altogether for equally weighted (EW) and value-weighted (VW) methods to check whether a certain strategy (or some strategies) could be recommended to portfolio managers as the best (better) strategy (strategies). The paper aims to discuss these issues.

Design/methodology/approach
– This paper uses the stochastic dominance (SD) approach, a non-parametric test, to investigate the relative performance among various strategies and help investors search for the best or better strategy (strategies).

Findings
– The main results show that both the highest E/P and CF/P strategies (and their corresponding premiums) generally produce higher returns than the other three strategies (and their corresponding premiums) through allocating investors’ capital between the risky and risk-free assets for the EW and VW methods, respectively.

Research limitations/implications
– This study only examines US stock markets by SD approach, whether the results are consistent with non-US markets still needs further investigation. The findings imply that investors can benefit by investing in the highest E/P or CF/P stocks (or their corresponding premiums) to make more profit or less loss for US stock markets.

Practical implications
– First, the SD findings suggest that investors or portfolio managers can allocate their funds between risky and risk-free assets to maximize their profits. Next, the simulation results again prove that the profits of each nonzero-investment or zero-investment strategy for EW portfolios are higher than those of each corresponding strategy for VW portfolios. Finally, the findings imply that portfolio managers or investors can invest in the highest E/P or CF/P stocks (or their corresponding premiums) to make more profit or less loss.

Originality/value
– This study first uses an extensive data set (1952-2009) to examine the relative performance of nonzero-investment strategies and their corresponding zero-investment strategies for the five popular indicators altogether for the EW and VW methods with the SD approach for US stock markets. Moreover, the results reveal that the investors or portfolio managers can invest in the highest E/P and/or CF/P portfolios (or their corresponding premiums) to make more profit or less loss.
Finance and growth: new evidence from meta-analysis
Authors: Asongu Simplice A. 
Published: June 2015

Purpose– The purpose of this paper is to bridge the gap between the pros and cons of a questionable finance-growth nexus.Design/methodology/approach– Over 20 fundamental characteristics that have influenced the debate over the last decades have been examined. The empirical evidence is based on 196 outcomes from 20 studies. The author assesses the degree of heterogeneity and identify causes of the observed differentiation.Findings– The findings also show evidence of publication bias. Overall, a genuine effect exists between financial development and economic growth. A finance-growth nexus might not be appealing in our era because of: endogeneity-based estimations, publication bias, and effects of financial activity. A historical justification has also been discussed.Practical implications– Encouraging the publication of results with findings that are not consistent with the mainstream positive finance-growth nexus should provide new scholarly insights into the relationship. Depending on the specific context of sampled countries, the role of policy has also been to encourage financial development through measures that may expose countries to negative external shocks like financial crises. Policy makers that have been viewing the challenges of development exclusively from this point of view for the rewards of growth may not be getting the financial dynamics correctly.Originality/value– Very few meta-analysis studies have focused on the finance-growth nexus.
How important are early investment experiences on subsequent investment decisions? A laboratory experiment on asset allocation
Authors: Papadovasilaki Dimitra , Guerrero Federico , Sundali James , Stone Gregory 
Published: June 2015

Purpose
– The purpose of this paper is to examine the influence of early investment experiences on subsequent portfolio allocation decisions in a laboratory setting.

Design/methodology/approach
– In an experiment in which the task consisted of allocating a portfolio between a risky and riskless asset for 20 periods, two groups of subjects were confronted with either a market boom or bust in the initial four periods.

Findings
– The findings suggest that after controlling for demographic characteristics, the timing of a boom or bust during the investment lifecycle matters greatly. Subjects that faced a bust early in their investment lifecycle held less of the risky asset in subsequent periods compared to subjects who experienced an early boom.

Originality/value
– To the best of the authors knowledge this is the first laboratory study investigating the role of early aggregate shocks on subsequent investment behavior.
Is the construction industry aware of supply chain management? The Portuguese contractors’ perspective
Authors: Arantes Amílcar , Ferreira Luís Miguel D. F. , Costa António Aguiar 
Published: June 2015

Purpose
– The purpose of this paper is to evaluate the understanding and behaviour of construction companies in relation to supply chain management (SCM) and how those relationships can impact the adoption of the SCM concept.

Design/methodology/approach
– This paper adopted a descriptive study method based on a cross-section survey. A literature review and focus group interviews were used to design the survey questionnaire. The focus group interviews were also used to discuss the results of the survey and draw conclusions.

Findings
– The results show that the global awareness level of SCM and the relationships level among the entities in the Portuguese construction industry are low, which is in alignment with previous research work. These results also show that SCM in the construction industry is a complex task due to the fact that the relationships between the entities are different, and also often contractors and subcontractors change roles from project-to-project.

Research limitations/implications
– The limited number of valid responses in the research, particularly when considering categories based on the size of the contractors, can be considered a major limitation of this research, which might have reduced the quality of the statistic tests performed.

Practical implications
– Construction companies should foster a proper understanding of “the language” and core concepts underpinning SCM practices and should pay particular attention to a systemic and network perspective, avoiding the traditional focus on the management of dyadic relationships. Accordingly, care must be taken to avoid the “simple and direct” transfer of the SCM concept to the construction sector.

Originality/value
– This paper provides contributions to understanding the awareness of SCM within the construction industry and to the field of SCM, confirming that it is the specifics, and not the context, of the construction sector that are not well-adapted to the assumptions underpinning SCM and related concepts.
Exploring information sharing in the extended supply chain: an interdependence perspective
Authors: Kembro Joakim , Selviaridis Kostas 
Published: June 2015

Purpose– This paper aims to empirically explore demand-related information sharing in the extended supply chain.Design/methodology/approach– Through a single, embedded case design, a range of methods are used to collect data from companies representing three different supply chain tiers, including focal company, first-tier suppliers and first-tier customers. The collected data are analysed through the theoretical lens of interdependence.Findings– The findings indicate that the supply chain actors adapt information sharing to the pooled, serial or reciprocal type of interdependence. Information sharing is thus increased with key dyadic partners representing, for example, unique offerings and high market shares as percentage of total expenditure/sales. The study also unearths several barriers to information sharing beyond dyadic ties, including problems related to dis-aggregated, misinterpreted and/or incomplete information.Research limitations/implications– The study empirically contributes to the existing literature by exploring information sharing in the extended supply chain and by suggesting different approaches to information sharing depending on the type and intensity of interdependence between supply chain partners. Further, the paper contributes to the existing literature on barriers of information sharing in supply chains by identifying barriers specific to multi-tier information sharing. “Meta-information” (i.e. information about the shared information) is needed to overcome some of the barriers of sharing information in cases of weak, pooled interdependencies in the supply chain.Practical implications– Similar to previous empirical research, this exploratory study indicates that companies, in general, refrain from sharing information beyond dyadic ties. Supply chain managers would instead mostly focus on stronger, reciprocal interdependencies and emphasise dyadic information sharing. To further guide managers, a demand profiling framework considering market share and demand uncertainty is presented. It may be interesting to engage in multi-tier information sharing in particular cases where strong interdependence exists between three or more partners.Originality/value– This study contributes to existing research on information sharing in supply chains by empirically studying information sharing in an extended supply chain, applying interdependence theory as its analytical framework and unearthing several barriers that are specific to multi-tier information sharing.
Going above and beyond: how sustainability culture and entrepreneurial orientation drive social sustainability supply chain practice adoption
Authors: Marshall Donna , McCarthy Lucy , McGrath Paul , Claudy Marius 
Published: June 2015

Purpose– This paper aims to examine what drives the adoption of different social sustainability supply chain practices. Research has shown that certain factors drive the adoption of environmental sustainability practices but few focus on social supply chain practices, delineate which practices are adopted or what drives their adoption.Design/methodology/approach– The authors examine the facilitative role of sustainability culture to explain the adoption of social sustainability supply chain practices: basic practices, consisting of monitoring and management systems and advanced practices, which are new product and process development and strategic redefinition. The authors then explore the role played by a firm’s entrepreneurial orientation in shaping and reinforcing the adoption of social sustainability supply chain practices. A survey of 156 supply chain managers in multiple industries in Ireland was conducted to test the relationship between the variables.Findings– The findings show that sustainability culture is positively related to all the practices, and entrepreneurial orientation impacts and moderates social sustainability culture in advanced social sustainability supply chain adoption.Research limitations/implications– As with any survey, this is a single point in time with a single respondent. Implications for managers include finding the right culture in the organisation to implement social sustainability supply chain management practices that go beyond monitoring to behavioural changes in the supply chain with implications beyond the dyad of buyer and supplier to lower tier suppliers and the community surrounding the supply chain.Practical implications– The implications for managers include developing and fostering cultural attributes in the organisation to implement social sustainability supply chain management practices that go beyond monitoring suppliers to behavioural changes in the supply chain with implications beyond the dyad of buyer and supplier to lower tier suppliers and the community surrounding the supply chain.Originality/value– This is the first time, to the authors’ knowledge, that cultural and entrepreneurial variables have been tested for social sustainability supply chain practices, giving them new insights into how and why social sustainability supply chain practices are adopted.
Synergistic effects of fire and elephants on arboreal animals in an African savanna

Published: June 2015

Summary

Disturbance is a crucial determinant of animal abundance, distribution and community structure in many ecosystems, but the ways in which multiple disturbance types interact remain poorly understood. The effects of multiple‐disturbance interactions can be additive, subadditive or super‐additive (synergistic). Synergistic effects in particular can accelerate ecological change; thus, characterizing such synergies, the conditions under which they arise, and how long they persist has been identified as a major goal of ecology.

We factorially manipulated two principal sources of disturbance in African savannas, fire and elephants, and measured their independent and interactive effects on the numerically dominant vertebrate (the arboreal gekkonid lizard Lygodactylus keniensis) and invertebrate (a guild of symbiotic Acacia ants) animal species in a semi‐arid Kenyan savanna.

Elephant exclusion alone (minus fire) had negligible effects on gecko density. Fire alone (minus elephants) had negligible effects on gecko density after 4 months, but increased gecko density twofold after 16 months, likely because the decay of fire‐damaged woody biomass created refuges and nest sites for geckos. In the presence of elephants, fire increased gecko density nearly threefold within 4 months of the experimental burn; this occurred because fire increased the incidence of elephant damage to trees, which in turn improved microhabitat quality for geckos. However, this synergistic positive effect of fire and elephants attenuated over the ensuing year, such that only the main effect of fire was evident after 16 months.

Fire also altered the structure of symbiotic plant‐ant assemblages occupying the dominant tree species (Acacia drepanolobium); this influenced gecko habitat selection but did not explain the synergistic effect of fire and elephants. However, fire‐driven shifts in plant‐ant occupancy may have indirectly mediated this effect by increasing trees' susceptibility to elephant damage.

Our findings confirm the importance of fire × elephant interactions in structuring arboreal wildlife populations. Where habitat modification by megaherbivores facilitates co‐occurring species, fire may amplify these effects in the short term by increasing the frequency or intensity of herbivory, leading to synergy. In the longer term, tree mortality due to both top kill by fire and toppling by large herbivores may reduce overall microhabitat availability, eliminating the synergy.
Moving Slowly up the Ladder of Political Engagement: A ‘Spill-over’ Model of Internet Participation
Authors: Cantijoch Marta , Cutts David , Gibson Rachel 
Published: June 2015

This article: Confirms that e-participation is multi-dimensional with prior modes of participation emerging online. Shows that these online activities have mobilising effects and that this relationship appears to work largely in a step-wise or ‘spill-over’ manner. Demonstrates that accessing online news and information acts as a ‘gateway’ or first step into participation. Argues that the more active modes of online participation do not appear to exert any mobilising effects on other types of post-election engagement. Shows that the dynamics of Internet participation are more complex than the ‘one size fits all’ approach that dominates the current literature. In this study we test whether a range of online political activities undertaken during the campaign affect the propensity to engage in non-electoral types of online and offline political engagement subsequently. We develop three hypotheses accounting for this linkage based on a ‘spill-over’ logic about (1) the effort required for the action; (2) the type of activity undertaken (formal versus informal); and (3) the medium on which the action occurs (online or offline). We test our hypotheses with a pre/post-election panel dataset from the UK 2010 General Election. The results show that after controlling for prior political engagement, online information seeking during the campaign has a significant and positive effect on further engagement in ‘softer’ discussion modes of participation. The findings are seen to confirm that Internet-based political mobilisation works in a ‘step-wise’ manner whereby lower intensity activities spill-over to move individuals a little further up the participation ladder.
Why Do Voters Lose Trust in Governments? Public Perceptions of Government Honesty and Trustworthiness in Britain 2000–2013
Authors: Whiteley Paul , Clarke Harold D. , Sanders David , Stewart Marianne 
Published: June 2015

This article: Notes that public perceptions that governments are honest and trustworthy are surprisingly volatile over time, but they move together in a long-term equilibrium relationship with indicators of policy performance and perceptions of fairness of the decision-making process. Argues that if individuals feel that policy delivery, particularly in relation to the economy, is working well then they will trust the government of the day even if they oppose a particular decision. Maintains that if they feel that the process of governing is unfair then they are likely to view the government as being both dishonest and untrustworthy. Indicates that evaluations of political leaders are powerful heuristics for allowing voters to judge the honesty and trustworthiness of a government. Provides evidence that there is a long-term trend decline in perceptions of government honesty even after taking into account policy process and performance. The aim of this article is to analyse trends in public perceptions of the honesty and trustworthiness of British governments over the period 2000 to 2013, years of great political and economic change in British society. These perceptions are surprisingly volatile over time, but they are stimulated by general elections and even more so by a change of government. Perceptions of government honesty can be understood to be the product of both policy delivery and public attitudes to the way democracy works in Britain. If individuals feel that economic policies and the delivery of public services are working well and also that democracy is effective, then they will trust the government of the day. In addition perceptions of government trustworthiness are strongly influenced by the public’s evaluations of the Prime Minister, since the voters use this as a heuristic to judge the honesty of a government.
