Australian industry superannuation funds
Authors: Reddy Wejendra , Higgins David , Wist Mark , Garimort John 
Published: July 2013

PurposeTo achieve long‐term performance, superannuation balanced funds typically invest in a range of defined asset classes based on a strategic asset allocation approach. In an Australian context, the purpose of this paper is to examine the performance of the balanced investment option against eight different investment strategies and how the property allocation changes with different asset allocation models.Design/methodology/approachThe analysis is based on ex post data covering 17 years (1995 to 2011). The selected passive and active allocation models are set within the modern portfolio theory framework utilising Australian ten year bonds as the risk free rate. The Sharpe ratio is used as the key risk‐adjusted return performance measure.FindingsProperty provided the second highest risk adjusted return profile behind the alternative asset class. The different asset allocation models perform as well as the conventional strategic approach and in many instances property allocation is found to be under‐allocated on a return optimisation basis. Depending on the asset allocation model, property when included within a multi‐asset portfolio improves the portfolio risk‐adjusted return profile by 2 per cent to 28 per cent.Practical implicationsFor an Australian superannuation balanced fund, the empirical results show that there is scope to increase the property allocation level from current 10 per cent to 23 per cent. This knowledge will be beneficial for funds currently re‐profiling investment portfolios to achieve stable risk‐adjusted returns.Originality/valueThe research contributes to both practical and academic fields, as it offers a methodological approach on how allocation to property assets can be improved using a series of passive and active asset allocation strategies.
An investigation into the drivers of Australian REIT merger and acquisition announcements
Authors: Ratcliffe Chris , Dimovski Bill 
Published: July 2013

PurposeThe purpose of this paper is to use Australian Real Estate Investment Trust (A‐REIT) data to empirically examine potential influencing factors on A‐REITs becoming a bidder or a target in the mergers and acquisitions (M&A) area.Design/methodology/approachThis study uses logistic regression analysis to investigate the odds of publically traded A‐REITs being either a bidder or a target as a function of a number of financial and corporate governance variables.FindingsPrior research in the US REIT M&A area has shown that target size is inversely related to takeover likelihood; in contrast, the authors' Australian results show that size has a positive impact. Prior research on share price and asset performance has shown that underperformance increases the odds of an entity becoming a target, but this paper's results further support these findings and provide confirmation of the inefficient management hypothesis. For acquirers it was found that leverage, cash balances, management structure, the level of shares held by related parties and the global financial crisis have an important impact on bidder likelihood.Practical implicationsGiven that the literature suggests that investors can earn significant positive abnormal returns by owning targets, but incur significant abnormal losses by owning bidders, at announcement, this study will be useful to fund managers and other investors in A‐REITs by investigating the characteristics of those firms that become targets and bidders.Originality/valueThis paper adds to the recent US REIT M&A literature by examining the second biggest REIT market in the world and reporting a number of factors that might influence A‐REITs to become targets or bidders.
Property cycles
Authors: Grover Richard , Grover Christine 
Published: July 2013

PurposeThe purpose of this paper is to review what is known about property cycles following the financial crisis of 2008.Design/methodology/approachThe method is to review the literature on property cycles published since the 1930s, to examine the extent to which endogenous causes have been identified as distinct from exogenous factors that may have produced cyclicality resulting from weak adjustment mechanisms but not cycles.FindingsWhilst there is broad consensus that the property market has delays in adjustment which produce oscillations resulting from external shocks, it is more difficult to identify endogenous causes of cycles, though there are some possible candidates, notably technical progress.Practical implicationsThe slump after 2008 has cost savers and taxpayers dear, so better means of predicting cycles so that policy makers can mitigate them is desirable.Originality/valueThe debate about whether property cycles result from exogenous shocks or endogenous causes is in danger of being lost sight of. If the former, then the property industry is a channel through which external factors feed through to the economy, albeit magnified by weak adjustment factors. If there are endogenous causes, then policy makers would be unwise to overlook their potential destabilising impact on the economy.
Underpinning theories: order‐of‐use in information systems research
Authors: Iyamu Tiko 
Published: July 2013

PurposeThe paper was intended to demonstrate the use and order of a combined lenses of two theories in IS research. It helps to understand how theories could be adopted in the order of methodological value. The way data are collected, organised and analysed is influenced and shaped by the order of use of the underpinning theories. The importance of the order is to create consistency, predictability, and uniformity of analysis, which have impact on the findings.Design/methodology/approachReview of literature, and teaching and supervision experiences were used in the approach.FindingsThe result of a combined use of both ST and ANT in the same study has been less than expected. The application of theories helps exhume findings. This makes the order‐of‐use of application of the theories significant. Some studies applied ST before ANT, and vice versa. There has never been a model or framework which defines the order‐of‐use of the theories. It could be argued that it depend on the nature and objectives of the study. This paper focuses on order‐of‐use of combined theories in information systems studies. No organisation has total power to determine what the choice(s) of an actor will be in a particular situation. Actor and structure by virtue of their interaction recursively produces and reproduces, on the one hand and on another, the actor and structure enable and at the same time there are constraints.Originality/valueBoth theories can be used as a way of thinking and speaking about the phenomena being studied and also, as a “lens” through which the data is viewed and interpreted.

Authors: Grujicic M. , Snipes J.S. , Chandrasekharan N. , Ramaswami S. 
Published: July 2013

PurposeThe purpose of this paper is to assess the blast‐mitigation potential and the protection ability of an air‐vacated buffer placed in front of a target structure under realistic combat‐theatre conditions.Design/methodology/approachThe blast‐mitigation efficacy of the air‐vacated buffer concept is investigated computationally using a combined Eulerian‐Lagrangian (CEL) fluid‐structure interaction (FSI) finite‐element analysis.FindingsThe two main findings resulting from the present work are: the air‐vacated buffer concept yields significant blast‐mitigation effects; and the buffer geometry and vacated‐air material‐state parameters (e.g. pressure, mass density, etc.) may significantly affect the extent of the blast‐mitigation effect.Originality/valueThe main contribution of the present work is a demonstration of the critical importance of timely deployment of the buffer relative to the arrival of the incident wave in order to fully exploit the air‐vacated buffer concept.

Authors: Singh Baljeet 
Published: July 2013

PurposeThe purpose of this paper is to compute the phase velocities and attenuation coefficients of coupled longitudinal waves in a generalized thermoporoelastic model and to observe the effect of porosity, frequency and thermal parameters on the phase velocities and attenuation coefficients on these waves graphically.Design/methodology/approachThe linear governing equations of a generalized thermoporoelastic model in the context of Lord and Shulman theory of generalized thermoelasticity are solved with the help of plane harmonic solution method to show the existence of one shear and three kinds of coupled longitudinal waves.FindingsThe results obtained show the dependence of phase velocities and attenuation coefficients of coupled longitudinal waves on frequency, porosity, relaxation times and other material parameters.Originality/valueThe problems on coupled heat‐fluid flow in a saturated deformable porous medium are important in various engineering fields, for example, petroleum engineering, chemical engineering, pavement engineering and nuclear waste management. A new generalized thermoporoelastic model is formulated to study the wave phenomena and their dependence on various material parameters.
Reflection and transmission at the plane boundary of elastic half‐space and initially stressed thermoelastic diffusion with voids half‐space
Authors: Kumar Rajneesh , Kumar Rajeev 
Published: July 2013

PurposeThe purpose of this research is to study the reflection and transmission of elastic waves at the interface of an elastic half‐space and initially stressed thermoelastic diffusion with voids half‐space.Design/methodology/approachTwo‐dimensional model has been considered of an isotropic elastic half‐space (Medium I) lying over a homogeneous isotropic generalized initially stressed thermoelastic diffusion with voids half‐space (Medium II). There exist two waves, P‐wave and SV‐wave, in isotropic elastic half‐space and four quasi‐longitudinal waves, namely, quasi‐longitudinal wave (QP‐mode), quasi‐longitudinal mass diffusive wave (QMD‐mode), quasi‐longitudinal thermal wave (QPT‐mode) and quasi‐longitudinal volume fractional wave (QPV‐mode), and one quasi‐transverse wave (QSV‐mode) exists in initially stressed thermoelastic diffusion with voids half‐space.FindingsThe energy ratios of these waves are computed along various directions of incident wave, and it is found that the sum of all energy ratios is exactly unity at each value of incident angle. The amplitude ratios of various waves have been obtained numerically.Originality/valueReflection and transmission of an elastic medium is of great practical importance. Since valuable organic and inorganic deposits beneath the earth surface are difficult to detect by drilling randomly, wave propagation is the simplest and most economic technique for these and does not require any drilling through the earth. Almost all the oil companies rely on seismic interpretation for selecting the sites for exploratory oil wells because seismic wave methods have higher accuracy, have higher resolution and are more economical, as compared to drilling which is expansive and time consuming.

Supporting the research process through expanded library data services
Authors: Wang Minglu 
Published: July 2013

PurposeThe purpose of this paper is to describe how the authors gained a better understanding of the variety of library users' data needs, and how gradually some new data services were established based on current capabilities.Design/methodology/approachThis paper uses a case study of the new data services at the John Cotton Dana Library, at Rutgers, The State University of New Jersey, Newark campus, to demonstrate the possible ways to extend data reference services and provide data computing services. A content analysis of services records shows how each user group falls into the multiple data services levels and subcategories.FindingsLibrary users can be classified into many different categories, and each of these may have different needs. Research centers might have big projects involving data gathering and applications where a librarian can mainly provide consultation; while an individual faculty member or student might need the librarians as research partners, with help for their specific problems. Computing data services can involve group training and statistical analysis assistance, where researchers need emergent help. Data librarians can take various opportunities for data management education, thereby gradually raising awareness and cultivating better research habits among researchers.Originality/valueLibrary data computing services can make unique contributions to faculty and students' research and study. Institution, library and users' interaction determines the levels and extent of data services and is generalized from the description and analysis of typical data service examples. Classic concept of data services levels is applied to a concrete case of data services program, and sub‐categories of each data services level and user types are developed based on the authors' services record.
Integrated access to cultural heritage information pieces in Iran over Imam Reza's 4th Zarih (burial chamber) as a sample
Authors: Farrokhnia Maliheh , Zarei Mitra 
Published: July 2013

PurposeThe purpose of this paper is to offer an example of how ontology, such as CIDOC, can be turned into a format from the perspective of an object. In fact, it illustrates the possible semantic analysis of an object description into a view neutral machine‐interpretable form. The aim is to show that a museum object located in a museum can be described in detail and then related to other information objects located in other memory institutions such as libraries and archives.Design/methodology/approachStudying different documents, all the information about Imam Reza's Zarih 4th was derivated. Then the most important were listed and represented in detail, according to CIDOC CRM entities.FindingsThe figures explicitly reveal the existing semantic correlations between the heterogeneous cultural heritage information in various memory institutions, such as Organization of Libraries, Museums and Documents Centre of Astan Quds Razavi.Originality/valueThe authors capture the knowledge from different resources and relate them in a semantic description with the aid of a semantic conceptual model like CIDOC CRM, to show more effective information integration in a cultural institution such as Organization of Libraries, Museums and Documents Centre of Astan Quds Razavi, in order to provide unified access to collection‐level information.
A survey on the exchange of linguistic resources
Authors: Lezcano Leonardo , Sánchez‐Alonso Salvador , Roa‐Valverde Antonio J. 
Published: July 2013

PurposeThe purpose of this paper is to provide a literature review of the principal formats and frameworks that have been used in the last 20 years to exchange linguistic resources. It aims to give special attention to the most recent approaches to publishing linguistic linked open data on the Web.Design/methodology/approachResearch papers published since 1990 on the use of various formats, standards, frameworks and methods to exchange linguistic information were divided into two main categories: those proposing specific schemas and syntaxes to suit the requirements of a given type of linguistic data (these are referred to as offline approaches), and those adopting the linked data (LD) initiative and the semantic web technologies to support the interoperability of heterogeneous linguistic resources. For each paper, the type of linguistic resource exchanged, the framework/format used, the interoperability approach taken and the related projects were identified.FindingsThe information gathered in the survey reflects an increase in recent years in approaches adopting the LD initiative. This is due to the fact that the structural and syntactic issues which arise when addressing the interoperability of linguistic resources can be solved by applying semantic web technologies. What remains an open issue in the field of computational linguistics is the development of knowledge artefacts and mechanisms to support the alignment of the different aspects of linguistic resources in order to guarantee semantic and conceptual interoperability in the linked open data (LOD) cloud. Ontologies have proved to be of great use in achieving this goal.Research limitations/implicationsThe research presented here is by no means a comprehensive or all‐inclusive survey of all existing approaches to the exchange of linguistic resources. Rather, the aim was to highlight, analyze and categorize the most significant advances in the field.Practical implicationsThis survey has practical implications for computational linguists and for every application requiring new developments in natural language processing. In addition, multilingual issues can be better addressed when semantic interoperability of heterogeneous linguistic resources is achieved.Originality/valueThe paper provides a survey of past and present research and developments addressing the interoperability of linguistic resources, including those where the linked data initiative has been adopted.

Authors: Isfandyari‐Moghaddam Alireza , Sedehi Maryam , Dehghani Mozhdeh , Nemati‐Anaraki Leila , Hasanzadeh‐Dizaji Elaheh 
Published: July 2013

PurposeThe purpose of this paper is to compare the attitude of the managers of libraries located at Iran, Tehran and Shahid Beheshti Medical Sciences Universities' training hospitals, on the status of information technology (IT) in the mentioned libraries.Design/methodology/approachThis study employed a researcher‐made questionnaire. The managers of 40 hospital libraries of Iran, Tehran and Shahid Beheshti Universities formed the population of the research. To analyze the collected data, the statistical software SPSS (version 17) was used.FindingsResults showed that 12.5 per cent of Tehran, 15.6 per cent of Iran and 25 per cent of Shahid Beheshti Universities library managers agreed, to a very large extent, on the application and development of IT and its tools and 93.7 per cent of the managers from all three hospital libraries deemed the application of IT most necessary. The managers believed that the greatest advantage of IT is concerned with the reduction of human efforts (59.4 per cent), and 100 per cent of the managers acknowledged the need for further promotion of their skills in a wide variety of IT issues. In total, 16.1 per cent at Tehran, 12.9 per cent at Iran and 29 per cent at Shahid Beheshti University considerably approved of formal education for the promotion of their librarians' skills.Originality/valueThis study is a step towards acknowledging the contribution, status, and value of hospital libraries to the health sector by the library managers in theory and practice, in the shadow of considering their librarians as network experts, information media and system designers, and technology experts.
The Trojan hives: pollinator pathogens, imported and distributed in bumblebee colonies
Authors: Graystock Peter , Yates Kathryn , Evison Sophie E. F. , Darvill Ben , Goulson Dave , Hughes William O. H. 
Published: July 2013

Summary

Over a million commercially produced bumblebee colonies are imported annually on a global scale for the pollination of greenhouse crops. After importation, they interact with other pollinators, with an associated risk of any parasites they carry infecting and harming native bees. National and supranational regulations are designed to prevent this, and commercially produced bumblebee colonies are accordingly now often sold and imported as being parasite‐free.

Here, we used molecular methods to examine the occurrence of parasites in bumblebee colonies that were commercially produced in 2011 and 2012 by three producers. We then used controlled experiments to determine whether any parasites present were infectious.

We found that 77% of the commercially produced bumblebee colonies from the three producers, which were imported on the basis of being free of parasites, in fact carried microbial parasites, with five different parasites being detected across the total sample of bumblebees and a further three in the pollen supplied with the colonies as food.

Our controlled experiments demonstrated that at least three of these parasites were infectious to bumblebees with significant negative effects on their health. Furthermore, we also found that at least four of the parasites carried by commercially produced bumblebees were infectious to honeybees, indicating that they pose a risk to other pollinators as well.

Synthesis and applications. The results demonstrate that commercially produced bumblebee colonies carry multiple, infectious parasites that pose a significant risk to other native and managed pollinators. More effective disease detection and management strategies are urgently needed to reduce the pathogen spillover threat from commercially produced bumblebees.
