Published: June 2015

Purpose:
To determine the safety and efficacy of fresh, human sclera allografts as a patch graft material in glaucoma drainage device (GDD) surgery.

Design:
Retrospective, noncomparative, interventional, consecutive case series.

Subjects:
All GDD cases operated between 2008 and 2013 in which fresh human corneoscleral rims were used immediately after the central corneal button was used for penetrating or endothelial keratoplasty.

Methods:
Surgery was performed by 2 surgeons at 2 facilities. The Ahmed Glaucoma Valve (FP-7) was used exclusively in this cohort. Sixty-four eyes of 60 patients were identified; demographic data were recorded along with intraocular pressure (IOP), medication requirements, visual acuity, complications, and subsequent interventions.

Main Outcome Measures:
Incidence of complications. IOP and medication requirements at the last follow-up. Quilified success utilizing Tube Versus Trabeculectomy study criteria.

Results:
The mean age of the cohort was 66.2±19.1 years; the average preoperative IOP was 33.2±11.1 mm Hg on 4.2±1.3 IOP-lowering agents before GDD surgery. IOP decreased significantly to 14.1±4.7 mm Hg (P<0.001) on 1.6±1.2 IOP-lowering agents (P<0.001) after an average follow-up of 18.2±15.4 months. There were no cases of early or late blebitis or endophthalmitis, and there was 1 case of conjunctival erosion and tube/plate exposure (1.6%) occurring 30 days after surgery. Qualified success was estimated as 90.5% and 81% at 1 and 2 years, respectively, using Tube Versus Trabeculectomy study criteria.

Conclusions:
Heterologous, fresh, human donor sclera appears to be a safe material for GDD tube coverage. It provides a cost-efficient alternative compared with traditional patch graft materials associated with a low risk of pathogen transmission.

Abstract
The mandible is the largest facial bone as well as the most commonly fractured bone in the maxillofacial region. Despite numerous studies conducted to identify optimal treatment modalities and plates configurations for intraoral and transoral approaches, no definitive conclusion has been reached.
This study used finite element analysis (FEA) to assess 4 scenarios for treatment of an angle fracture (6-hole noncompression miniplate; 6-hole single plate/Champy's technique, 3D strut plate; 2 parallel 4-hole noncompression miniplates). Analysis included segmental displacement and Von Mises Stress evaluations of a 3D reconstruction of a human mandible.
Von Mises Stress values for plates did not vary significantly among treatment groups. Moreover, no significant differences were observed in cumulative displacement of segments subjected to vertical and horizontal loads, with all treatment configurations demonstrating clinical acceptability.
MDMA impairs response to water intake in healthy volunteers
Authors: Baggott Matthew J. , Garrison Kathleen J. 
Published: June 2015

AbstractHyponatremia is a serious complication of 3,4-methylenedioxymethamphetamine (MDMA) use. We investigated potential mechanisms in two double-blind, placebo-controlled studies. In study 1, healthy drug-experienced volunteers received MDMA or placebo alone and in combination with the alpha-1 adrenergic inverse agonist prazosin, used as a positive control to release antidiuretic hormone (ADH). In study 2, volunteers received MDMA or placebo followed by standardized water intake. MDMA lowered serum sodium, but did not increase ADH or copeptin, although the control prazosin did increase ADH. Water loading reduced serum sodium more after MDMA than after placebo. There was a trend for women to have lower baseline serum sodium than men, but there were no significant interactions with drug condition. Combining studies, MDMA potentiated the ability of water to lower serum sodium. Thus, hyponatremia appears to be a significant risk when hypotonic fluids are consumed during MDMA use. Clinical trials and events where MDMA use is common should anticipate and mitigate this risk.
Development strategies of small economies: Singapore, Hong Kong and Macao
Authors: Lam Newman M. K. 
Published: June 2015

Purpose– The purpose of this paper is to examine the economic development in Singapore, Hong Kong and Macao to find the reasons for the success.Design/methodology/approach– Applying economic development theories and using archival data to examine the development strategies of the three economies.Findings– There is no single model suitable for economic development for all, and small economies need to be strategically interventionist by either inducing development or balancing the disequilibria caused by development.Originality/value– This is the first comparative study to examine these three fast-growing small economies. The findings lend insight into Hirschman’s theory of unbalanced growth and Stiglitz’s assertion that different economies and conditions require different development strategies.
Hong Kong’s institutional incongruities and its tourism policy
Authors: Yew Chiew Ping 
Published: June 2015

Purpose
– With a focus on Hong Kong tourism policy, the purpose of this paper is to explain the Hong Kong government’s conundrum in addressing society’s concerns and controversies over the massive influx of mainland tourists in recent years.

Design/methodology/approach
– This paper adopts the approach of historical institutionalism, in which the notion of structural-power takes centre stage. It outlines some notable trends in Hong Kong’s tourist arrivals and highlights some of the controversies that have arisen before delving into how existing institutional arrangements and key actors have shaped Hong Kong’s tourism policy amid the city’s shifting social, political and economic contexts.

Findings
– The prevalence of business interests and the ideology of economism largely explain the Hong Kong government’s stasis in tackling the problems stemming from the large inflow of mainland visitors. Institutional arrangements in the post-handover period have further empowered the business class, giving it an edge over the unelected executive that lacks a popular mandate. Therefore, even if the central government has signaled its willingness to adjust the Individual Visit Scheme (IVS) policy, the Hong Kong government is unlikely to propose significant cuts to the inflow of IVS arrivals. Without further political reforms to boost the executive’s legitimacy and accountability to the Hong Kong people, it is doubtful that the government may emerge from its predicament in the near future.

Originality/value
– Through the lens of tourism policy and planning pertaining to inbound mainland visitors, this paper aims to assess the current state of governance in Hong Kong. It not only offers a timely look into Hong Kong’s political system 17 years after handover but also explores the extent to which apparent dysfunctions in the city’s governance today are a consequence of institutional incongruities in its political system.
Case-based reasoning and BIM systems for asset management
Authors: Motawa Ibrahim , Almarshad Abdulkareem 
Published: June 2015

Purpose– The next generation of Building Information Modelling (BIM) seeks to establish the concept of Building Knowledge Modelling (BKM). The current BIM applications in construction, including those for asset management, have been mainly used to ensure consistent information exchange among the stakeholders. However, BKM needs to utilise knowledge management (KM) techniques into building models to advance the use of these systems. The purpose of this paper is to develop an integrated system to capture, retrieve, and manage information/knowledge for one of the key operations of asset management: building maintenance (BM).Design/methodology/approach– The proposed system consists of two modules; BIM module to capture relevant information and case-based reasoning (CBR) module to capture the operational knowledge of maintenance activities. The structure of the CBR module was based on analysis of a number of interviews and case studies conducted with professionals working in public BM departments. This paper discusses the development of the CBR module and its integration with the BIM module. The case retaining function of the developed system identifies the information/knowledge relevant to maintenance cases and pursues the related affected building elements by these cases.Findings– The paper concludes that CBR as a tool for KM can improve the performance of BIM models.Originality/value– As the research in BKM is still relatively immature, this research takes an advanced step by incorporating the intelligent functions of knowledge systems into BIM-based systems which helps the transformation from the conventional BIM to BKM.
Digital model data distribution in civil engineering contracts
Authors: Whyte Andrew , Donaldson James 
Published: June 2015

Purpose
– The use of digital-models to communicate civil-engineering design continues to generate debate; this pilot-work reviews technology uptake towards data repurposing and assesses digital (vs traditional) design-preparation timelines and fees for infrastructure. The paper aims to discuss these issues.

Design/methodology/approach
– Extending (building-information-modelling) literature, distribution-impact is investigated across: quality-management, technical-applications and contractual-liability. Project case-study scenarios were developed and validated with resultant modelling-application timeline/fees examined, in conjunction with qualitative semi-structured interviews with 11 prominent stakeholder companies.

Findings
– Results generated to explore digital-model data-distribution/usage identify: an 8 per cent time/efficiency improvement at the design-phase, and a noteworthy cost-saving of 0.7 per cent overall. Fragmented opinion regarding modelling utilisation exists across supply-chains, with concerns over liability, quality-management and, the lack of Australian-Standard contract-clause(s) dealing directly with digital-model document hierarchy/clarification/reuse.

Research limitations/implications
– Representing a small-scale/snapshot industrial-study, findings suggest that (model-distribution) must emphasise checking-procedures within quality-systems and, seek precedence clarification for dimensioned documentation. Similarly, training in specific file-formatting (digital-model-addenda) techniques, CAD-file/hard-copy continuity, and digital-visualisation software, can better regulate model dissemination/reuse. Time/cost savings through digital-model data-distribution in civil-engineering contracts are available to enhance provision of society’s infrastructure.

Originality/value
– This work extends knowledge of 3D-model distribution for roads/earthworks/drainage, and presents empirical evidence that (alongside appropriate consideration of general-conditions-of-contract and specific training to address revision-document continuity), industry may achieve tangible benefits from digital-model data as a means to communicate civil-engineering design.
BIM in the operations stage: bottlenecks and implications for owners
Authors: Bosch Arnold , Volker Leentje , Koutamanis Alexander 
Published: June 2015

Purpose
– The use of Building Information Modelling (BIM) in the Netherlands is increasing. Studies show that BIM is mainly used in the lifecycle stages of initiation, development and realisation. Owners and operators are presumably yet to discover the added value of BIM for maintenance and information management within their organisations. The purpose of this paper is to investigate information management during the operations stage from the viewpoint of owners and determines the added value of BIM within this growing field of construction.

Design/methodology/approach
– This research is based on a literature review, explorative interviews and process modelling. In total, 21 semi-structured interviews were conducted among public real estate and infrastructure owners and operators, software companies, service providers and contractors.

Findings
– This paper provides empirical insights into the sources of inefficiency and ineffectiveness in the activities of Dutch semi-public and public clients. It finds that the current added value of BIM in the operations stage is marginal. The main reasons for this are a lack of alignment between the supply of and demand for information and the context-dependent role of information.

Practical implications
– The authors propose a structured approach that supports client organisations in establishing greater alignment between the supply of and demand for information, and a less context-dependent role for information during the operations stage.

Originality/value
– In contrast to previous studies, this paper offers a new perspective on BIM in the operations stage, a growing field of interest in practice and science.
A systems information model for managing electrical, control, and instrumentation assets
Authors: Love Peter E.D. , Zhou Jingyang , Matthews Jane , Sing Chun-Pong , Carey Brad 
Published: June 2015

Purpose– The purpose of this paper is to present a systems information model (SIM) that is akin to a building information model (BIM) and can be used by asset managers and staff to make more informed and quicker decisions about maintenance.Design/methodology/approach– The problems associated with managing assets are examined alongside recent international efforts to standardize methods of data collection for meeting the objectives of owners. A case study in the domain of electrical, control and instrumentation (ECI) documentation is examined in detail, with particular reference to the amelioration of errors and omissions in “as built” drawings in order to provide the underlying foundation to support effective asset management (AM).Findings– The findings show that object oriented data models such as SIM provide a robust structure for effective and efficient AM and associated leverage of benefits throughout the entire facility lifecycle of a project. In particular object oriented data enables appropriate and reliable information to be created as a project progresses through its lifecycle, at little cost to the creators.Originality/value– The above special approach to enabling data collection at the point of creation is in alignment with recent Government initiatives such as Construction Operations Building Information Exchange, which are beginning to gather traction within the industry. While the potential benefits for AM of such systems are espoused throughout the industry, there are few successful examples in existence with measurable realization of benefits.
BIM-FM and consequential loss: how consequential can design models be?
Authors: Olatunji Oluwole Alfred , Akanmu Abiola 
Published: June 2015

Purpose
– Building information modelling (BIM) offers a new direction of project implementation. It promotes integration of multiple lifecycle stages as well as multidisciplinary integration; whereas conventional approaches are primed on fragmentation. The purpose of this paper is to add to existing debates on the relationship between the rationality of the legal structures underlying fragmented project delivery and BIM’s ability to successfully foster integration across different lifecycle stages. A step further from extant arguments on whether BIM could be sufficiently serviced by the same legal provisions that had serviced fragmented relationships, the study opens up some new fronts regarding the consequences of shared trusts and reciprocity in an integrated project platform.

Design/methodology/approach
– In addition to a deep analysis of traditional literature on BIM and project management, the study draws its strength from two recent court cases on the limitations of disclaimers against breaches. It also targets court decisions on consequential loss and the duty of care to explain project team’s liabilities when BIM could not live to its theorized promises.

Findings
– The study shows that disclaimers are a weak protection against liabilities. As BIM offers a dynamic project environment, the study relies on decided cases to show that duty of care to a project (and its owners) is not entirely representable by prototype contract language. More importantly, the study concludes that the applications of BIM to facilities management are better supported on BIM’s new dimension of multidisciplinary integration, rather than a mere coalescing of deliverables across different lifecycle fragments.

Originality/value
– This work presents a novel approach to the debate on the potentiality of BIM to drive project success. It adds to the growing discourse on the legal implications of BIM by considering the potential of digital models as a valid and admissible contract instrument.
Pupils’ satisfaction with school mid-day meal program
Authors: Ali Jabir , Akbar Mohammad 
Published: June 2015

Purpose
– The purpose of this paper is to analyze the differences in pupils’ satisfaction on various aspects of mid-day meal (MDM) program in India across food catered by centralized and decentralized kitchens.

Design/methodology/approach
– The study is based on structured questionnaire survey through personal interviews of 1,200 school children of primary and upper primary schools of four districts of the state of Uttar Pradesh, India. Simple statistical tools such as descriptive statistics, factor analysis, t-test and analysis of variance (ANOVA) have been used for meaningful data analysis.

Findings
– Pupils’ responses on 17 attributes of their satisfaction on school meal program were reduced to four components − quality of food, social bonding, health and hygiene and availability of support infrastructure, using factor analysis technique. Findings show the perceived differences in satisfaction on various aspects of MDM program. Further, ANOVA indicate that there is significant difference in the satisfaction level on MDM supplied through centralized and decentralized kitchens.

Practical implications
– This study provides an understanding of pupils’ perceptions of school meal program in order to enable policy makers, school administration and caterers of MDM to design better food service delivery models.

Social implications
– Findings of the study clearly indicate that benefit of social bonding is an added advantage to continue the school meal program irrespective of the fact whether food is served through centralized or decentralized kitchens.

Originality/value
– There are several evaluation studies undertaken by various agencies to assess the impact of MDM program in India. However, there are only limited numbers of studies available, which have analyzed the children’s satisfaction on school MDM program across kitchen types.
Asymmetric relationships in networked agricultural innovation processes
Authors: Lambrecht Evelien , Kühne Bianka , Gellynck Xavier 
Published: June 2015

Purpose– In innovation networks, asymmetric relationships are both considered as an opportunity and a threat for the enhancement of innovation. The purpose of this paper is to investigate how much asymmetry Flemish farmers perceive in their relationships for innovation with colleagues, suppliers and buyers.Design/methodology/approach– In total, 86 farmers active in four different agricultural subsectors in Flanders were consulted, of which 38 via in-depth interviews and 48 in seven focus groups. Data were analysed using NVivo.Findings– The authors found that across subsectors, different players in innovation networks play different roles. Furthermore, the authors observed that the majority of farmers see their relationships more as a necessity for the farm to be able to function, than as an opportunity for innovation. If they collaborate for innovation, they often prefer symmetric relationships with similar companies on horizontal level. Vertical collaboration for innovation is not very popular in the sample.Practical implications– The findings suggest that farmers should take more actions to gain power in the chain and improve their skills with regards to negotiating with their suppliers or buyers. Furthermore, the authors found which characteristics of asymmetric relationships would foster the development of innovation processes.Originality/value– Empirical work studying the effects and impacts of asymmetric relationships for innovation from the SME’s perspective are still limited, especially in the agricultural sector. Furthermore, this sector is of practical relevance to study because the need for networking and innovation is very real.
Organization, responsibility and practice of food provision in home-help service
Authors: Fjellstrom Christina , Mattsson Sydner Ylva , Sidenvall Birgitta , Raats Monique M , Lumbers Margaret 
Published: June 2015

Purpose
– In the home help service, food provision is one common welfare service that involves different professionals at different levels within a social organisation. The purpose of this paper is to examine how different professionals involved in this sector view and describe their work and responsibilities.

Design/methodology/approach
– A qualitative study was designed based on interviews with 17 professionals representing different positions in the organisation, and an inductive thematic analysis was carried out.

Findings
– The various professionals’ views of food provision mainly focus on the meal box and other meals seem to receive much less attention. The professionals also illuminated their respective roles within the food provision organisation by means of boundaries and split responsibilities, and expressed a view of food provision as an issue for outsourcing. The restricted manner in which food provision was viewed and described illuminates a risk of food insecurity for dependent people in home help service situations.

Originality/value
– The restriction of how food provision was viewed and described illuminates a risk of food insecurity for dependent people in home help service.
