Authors: Lewine Eliza B. , Miller Patricia E. , Micheli Lyle J. , Waters Peter M. , Bae Donald S. 
Published: June 2015

Background:
Surgical treatment is recommended for patients with unstable osteochondritis dissecans (OCD) of the elbow. However, little information is available comparing the anticipated results from the host of techniques. In this investigation, clinical and radiographic resolution as well as return to sports rates were assessed in adolescent patients following loose body (LB) removal and drilling/microfracture of grade IV lesions.

Methods:
We reviewed 21 adolescents treated with LB removal and drilling/microfracture for grade IV elbow OCD. Patients with additional elbow pathology, prior elbow surgery, or <1 year follow-up were excluded. Clinical resolution was defined as resolution of tenderness and radiographic resolution as resolution of edema on magnetic resonance imaging (MRI). Return to sport rates and Timmerman scores were assessed. Mean clinical and MRI follow-up times were 2.2±1.19 and 2.4±1.54 years, respectively. Clinical and radiographic parameters associated with clinical and/or radiographic resolution or return to sports were determined using penalized likelihood logistic regression. Wilcoxon signed-rank tests were used to evaluate the change in range of motion and in Timmerman scores.

Results:
Fifteen (71.4%) patients had either clinical or radiographic resolution at most recent follow-up. Nine (50%) had complete resolution on MRI, whereas 13 (61.9%) were nontender at their follow-up. Four patients with recurrent LBs underwent revision surgery. There were no complications in the 21 index procedures. Eighteen (85.7%) patients returned to any sport, whereas 14 (66. 7%) returned to their primary sport. Elbow flexion and extension improved by medians of 12 and 21 degrees, respectively (P=0.002, 0.01). Timmerman scores improved by a median of 30 (P=0.001). Shorter duration of symptoms correlated with smaller OCD lesions (P=0.03) and with improved clinical or radiographic resolution and return to sport rates.

Conclusions:
The majority of patients with grade IV elbow OCD achieves clinical and/or radiographic resolution and return to sports 2 years after LB removal and drilling/microfracture. Recurrence may be seen, however, and further investigation is needed to assess the efficacy of this technique compared with other treatment strategies.

Bioabsorbable Pin Fixation in Late Presenting Pediatric Radial Neck Fractures
Authors: Fuller Corey B. , Guillen Phillip T. , Wongworawat Montri D. , Riedel Barth B. 
Published: June 2015

Background:
Current treatment algorithms for pediatric radial neck fractures reserve open treatment for severe residual angulation. There is a paucity of literature guiding treatment for delayed presentation resulting in malunion. Bioabsorbable pins have been used successfully for many other fracture types in the upper extremity. The purpose of this study is to determine whether open reduction, bioabsorbable fixation with an osteotomy when necessary is a reasonable treatment option in delayed pediatric radial neck fractures by assessing pain, range of motion, functional, and radiographic outcomes.

Methods:
Radial neck fractures were evaluated in 7 children, 4 to 12 years old, with delayed initial presentation averaging 20 days. Patients presented with an average angular deformity of 63 degrees and translational deformity of 57% (6.1 mm) in the AP plane, all with painful and reduced range of motion. Patients underwent open reduction and fixation with Self-Reinforced Poly-L-Lactic Acid pins after failed closed reduction. Four patients required formal osteotomies. Postoperative follow-up averaged 9.2 months and consisted of radiographic and clinical evaluation with Wong-Baker FACES Visual Analog scale and the Mayo Elbow Performance (MEP) score.

Results:
Final radiographs demonstrate an improvement in angular deformity by 56 degrees and translational deformity by 51%. Final clinical outcomes demonstrated significantly improved pain-free range of motion with excellent MEP scores in 6 of the 7 patients. One patient developed a radioulnar synostosis, subsequently undergoing synostosis excision with a final MEP score of 80/100. There was no evidence of physeal closure or avascular necrosis and no cases requiring hardware removal or complicated by local inflammatory reactions.

Conclusions:
This small series shows encouraging results in the treatment of pediatric radial neck fractures with delayed presentation using open reduction, bioabsorbable fixation, and when necessary an osteotomy. Bioabsorbable fixation may eliminate issues surrounding subsequent hardware removal and pin-site infections. Despite these encouraging results, radioulnar synostosis after open surgery is still a concern.

Level of Evidence:
Level IV—case series.
Rate and Risk Factors for Delayed Healing Following Surgical Treatment of Lateral Condyle Humerus Fractures in Children
Authors: Salgueiro Lissette , Roocroft Joanna H. , Bastrom Tracey P. , Edmonds Eric W. , Pennock Andrew T. , Upasani Vidyadhar V. , Yaszay Burt 
Published: June 2015

Background:
Lateral condyle humerus fracture nonunion after surgical fixation has been reported to be <1%. The purpose of this study was to evaluate the rate and risk factors for delayed healing of pediatric lateral condyle fractures after surgical fixation.

Methods:
Retrospective study of all operatively treated lateral condyle fractures at a single institution from 2006 to 2013 was performed. Radiographic evaluation included: measured fracture displacement at both presentation and after surgical fixation, fracture classification, and multiple parameters of pin configuration. Patients who had delayed healing were defined as those not healed by the eighth week of follow-up and were compared with those fractures that healed in <8 weeks to identify risk factors associated with delayed healing. Purposeful selection was utilized to identify factors for entry into a multivariate binary logistic regression model.

Results:
A total of 210 children were evaluated. Mean follow-up was 25 weeks (4 wk to 5 y). Distribution of Weiss classification was as follows: type 1, 8 (4%); type 2, 61 (29%); and type 3, 141 (67%). There were 33 (16%) delayed unions and 7 of these (3% of the entire cohort) required further surgery to achieve healing. Weiss classification, intraoperative fluoroscopy time, and intraoperative displacement after fixation met criteria for entry into the regression. While Weiss classification did not remain significant within the model, its removal resulted in a 30% change in the parameter estimate for intraoperative fluoroscopy time. For each second increase in fluoroscopy time, there is a 3% increase in the risk of delayed healing. Patients with >1 mm displacement of the lateral cortex after fixation had an increased risk of delayed healing (OR=4.78, P=0.007).

Conclusions:
Delayed union of lateral condyle fractures is a matter of concern, and the rate of secondary surgery to achieve healing appears to be higher than previously reported. Risks for delayed healing include amount of residual displacement after reduction and the difficulty in attaining that reduction, as defined by fluoroscopy time.

Level of Evidence:
Level IV—therapeutic study, case series.

AbstractDrosophila melanogasteris a valuable invertebrate model for viral infection and antiviral immunity, and is a focus for studies of insect-virus coevolution. Here we use a metagenomic approach to identify more than 20 previously undetected RNA viruses and a DNA virus associated with wildD. melanogaster. These viruses not only include distant relatives of known insect pathogens, but also novel groups of insect-infecting viruses. By sequencing virus-derived small RNAs we show that the viruses represent active infections ofDrosophila.We find that the RNA viruses differ in the number and properties of their small RNAs, and we detect both siRNAs and a novel miRNA from the DNA virus. Analysis of small RNAs also allows us to identify putative viral sequences that lack detectable sequence similarity to known viruses. By surveying >2000 individually collected wild adultDrosophilawe show that more than 30% ofD. melanogastercarry a detectable virus, and more than 6% carry multiple viruses. However, despite a high prevalence of theWolbachiaendosymbiont—which is known to be protective against virus infections inDrosophila—we were unable to detect any relationship between the presence ofWolbachiaand the presence of any virus. Using publicly available RNA-seq datasets we show that the community of viruses inDrosophilalaboratories is very different from that seen in the wild, but that some of the newly discovered viruses are nevertheless widespread in laboratory lines and are ubiquitous in cell culture. By sequencing viruses from individual wild-collected flies we show that some viruses are shared betweenD. melanogasterandD. simulans. Our results provide an essential evolutionary and ecological context for host-virus interaction inDrosophila, and the newly reported viral sequences will help developD. melanogasterfurther as a model for molecular and evolutionary virus research.DataAvailabilityAll of the relevant data can be found within the paper and its Supporting Information files, with the exception of raw metagenomic sequence data which are deposited at NCBI Sequence Read Archive (SRP056120), and sequence data which are deposited at Genbank (KP714070-KP714108,KP757922-KP757936andKP757937-KP757993)
Governing Singapore
Authors: Sun Tsai-Wei 
Published: June 2015

Purpose
– The purpose of this paper is to examine the impact of the Group Representation Constituency (GRC) system on the governance of Singapore, particularly in terms of equity and inclusiveness, accountability, and participation.

Design/methodology/approach
– Historical review and election data from Singapore government web site are used.

Findings
– The GRC system seems to be friendlier and fairer toward ethnic minorities than the traditional system. The GRC system also encourages political parties to be ethnically more inclusive. On the other hand, however, the GRC system has negative effects on opposition parties. A government cannot be called “accountable” if it lacks fair competition and sufficient popular participation.

Originality/value
– The Singapore experience shows that, in practice, ethnic equality/inclusiveness and even political stability on the one hand, and participation and accountability on the other hand, can present conflicts. Which value should receive priority thus requires serious consideration.
Urban governance and social sustainability
Authors: Chan Kin Sun , Siu Yeung Fai Philip 
Published: June 2015

Purpose
– The purpose of this paper is to evaluate the effectiveness of urban renewal policy by comparing urban renewal in Hong Kong with that undertaken in Macao.

Design/methodology/approach
– This study reviews the concepts of urban renewal in the two cities and examines related policies in Hong Kong and Macao.

Findings
– The study finds that the emphasis of urban renewal policy rests on the principles of self-financing, holistic planning and public-private partnerships. In order to deal with urban renewal issues, the Chinese Government has adopted a “People First, District-based, Public Participatory” approach based on public engagement and, to this end, it has introduced various measures, such as the District Urban Renewal Forum and the Urban Renewal Trust Fund. However, compared with Hong Kong, Macao’s efforts at urban renewal policies have been disjointed and piecemeal.

Originality/value
– The study adopts the principle of public management and compares the two cities’ urban policies to highlight the importance of both government leadership and public engagement for successful urban renewal.
BIM in facilities management applications: a case study of a large university complex
Authors: Kassem Mohamad , Kelly Graham , Dawood Nashwan , Serginson Michael , Lockley Steve 
Published: June 2015

Purpose– Building information modelling (BIM) in facilities management (FM) applications is an emerging area of research based on the theoretical proposition that BIM information, generated and captured during the lifecycle of a facility, can improve its management. Using this proposition as a starting point, the purpose of this paper is to investigate the value of BIM and the challenges affecting its adoption in FM applications.Design/methodology/approach– Two inter-related research methods are utilised. The literature is utilised to identify the application areas, value and challenges of BIM in FM. Due to the lack of case studies identified in the literature review, and to provide empirical evidence of the value and challenges of BIM in FM, a case study of Northumbria University’s city campus, is used to empirically explore the value and challenges of BIM in FM.Findings– The results demonstrated that BIM value in FM stems from improvement to current manual processes of information handover; improvement to the accuracy of FM data, improvement to the accessibility of FM data and efficiency increase in work order execution. The main challenges were the lack of methodologies that demonstrate the tangible benefits of BIM in FM, the limited knowledge of implementation requirement including BIM for FM modelling requirements, the interoperability between BIM and FM technologies, the presence of disparate operational systems managing the same building and finally, the shortage of BIM skills in the FM industry.Originality/value– There is lack of real-life cases on BIM in FM especially for existing assets despite new constructions representing only 1-2 per cent of the total building stock in a typical year. The originality of this paper stems from both adding a real-life case study of BIM in FM and providing empirical evidence of both the value and challenges of BIM in FM applications.
Contextualizing learning approaches which shape BIM for maintenance
Authors: Lindkvist Carmel 
Published: June 2015

Purpose– Studies of BIM examine the potential benefits in maintenance. There is also a perspective maintenance teams should be involved early in the building project process. The purpose of this paper is to address the lack of understanding on learning processes for BIM in maintenance in the early building project stage.Design/methodology/approach– Case study is used to examine the context maintenance learn about BIM. Maintenance managers and project managers were interviewed where discussions centred on a new build project which introduced BIM and how it would impact current practices.Findings– Learning happens at the early building project stage for BIM into maintenance influenced by external and internal contexts. The external context focuses on the UK government on being a catalyst for explorative learning. Meaning is added by maintenance teams through exploiting what is learnt from the external influence which is contextualized within current activities. Internal shaping of BIM is explored through building scenarios and exploitation learning occurs from past experiences of change which are inferred onto BIM. There is a necessary balance between exploration and exploitation learning in order to shape BIM for maintenance.Research limitations/implications– The paper is limited to one case study, however, it takes an in-depth look at the development of BIM in maintenance and how it is understood in maintenance.Originality/value– The contribution of the paper examines the context of learning in which BIM is shaped in maintenance.
Towards green building performance evaluation using asset information modelling
Authors: Alwan Zaid , Gledson Barry J. 
Published: June 2015

Purpose– The purpose of this paper is to provide a unique conceptual framework for integrated asset management strategy that includes making use of available facility assessment methods and tools such as BREEAM In-Use, and Leadership in Energy and Environmental Design (LEED); and highlights proposes areas of commonality between these and the use of as-built Building Information Modelling, that ultimately becomes the Asset Information Model (AIM). This framework will consider the emerging requirements for the capture of Building Performance Attribute Data (BPAD), and how these can be managed in order to assist with effective post-construction building performance evaluation.Design/methodology/approach– A review of the current process relevant to the development of as-built BIMs and AIMs was undertaken which included a discussion of BIM standards and of the COBie process. This was combined with data provided by industry practitioners. This led to the concept of BPADs being developed, to be used within existing green building tool, BREEAM In-Use, COBIE and FM/Asset management methods. In turn these methodologies were used to identify possible synergies and areas of integration in AIM-enabled environments.Findings– Recognising the cyclical nature of asset management and BIM, a conceptual model was generated. It was found that BPADs could be aggregated within an AIM model which could influence the delivery of effective facilities and asset management. The model considers the use of existing Building Management Systems (BMS) and Computer Aided Facility Management Systems (CAFMs) and identifies issues associated with the overall sustainability strategy.Originality/value– A conceptual framework is generated that proposes the use of effective information management and aggregation of BPAD within an AIM.
Factors affecting choice and image of ethnic restaurants in Serbia
Authors: Marinkovic Veljko , Senic Vladimir , Mimovic Predrag 
Published: June 2015

Purpose– With the expansion of dining out, visiting ethnic restaurants is becoming one of dominant trends worldwide. Given the fact that ethnic restaurants involve a number of peculiar elements that are not present when visiting regular “local” restaurants, the purpose of this paper is to identify the key determinants of choosing a particular ethnic-themed restaurant, as well as factors that have an impact on an ethnic restaurant’s perceived image.Design/methodology/approach– Research was done by conducting two separate studies. The first study identified factors that were generally the most significant to respondents when making a choice of an ethnic restaurant in which to dine. For the second study, a new sample of respondents – consisting of those who had just visited such an establishment – was used in order to determine which factors have the most significant impact on creating an image of ethnic restaurants. The research was therefore directed toward those restaurants where the customers can experience a unique atmosphere and ambiance that are synonymous within a given culture.Findings– The results obtained from the first study show that quality of food and price are the two most significant factors that determine which restaurant will be visited. On the other hand, the interior and exterior ranked as the two least important factors. In addition, the second study revealed that following the visit, the strongest impact on the restaurant’s image was its interior. Following interior, service quality surfaced as the most important antecedent of perceived image, while the impacts of price and exterior were weaker, but still statistically significant.Research limitations/implications– The study itself was done in two stages. In the first stage the analytical hierarchical process (AHP) model was used for ranking factors significant for choosing an ethnic restaurant, while in the second stage, structural equation modeling (SEM) model was used to identify triggers of perceived image after a visit to an ethnic restaurant. Future research should utilize both models to determine antecedents of the variables used. Apart from this, it is recommended to employ new variables that further explore the uniqueness of the ethnic restaurants.Originality/value– One of the main contributions of this work is related to combining of the AHP and SEM models, with the objective of completing a comparative results analysis, identifying in the process the positive aspects of both models and building a foundation for their coordination in terms of future use. This is significant, given that only a few prior studies have used such synergy.
The learning effect of a foodborne emergency exercise
Authors: Wahl Erik , Willumsen Birger , Jensvoll Laila , Finstad Ingunn Haavi , Berglund Turid Michelle 
Published: June 2015

Purpose
– The purpose of this paper is to describe a national foodborne emergency functional exercise conducted in 2013 by the Norwegian Food Safety Authority (NFSA), and focusses on how elements of the exercise: organization, scenario and evaluation contributed to learning effect to the organization.

Design/methodology/approach
– In total, 364 NFSA employees representing all offices and organization levels and representatives from cooperating governmental and business organizations participated. Scenario encompassed a salmonellosis outbreak traced to nationally distributed cured salmon seasoned with non-irradiated imported dill contaminated with Salmonella. Crisis communication was included. Exercise evaluation included questionnaires to participants, monitors reports and interviews with NFSA key personnel. Results were evaluated qualitatively and quantitatively.

Findings
– Participants and monitors judged the scenario as realistic and relevant and considered the exercise to have provided good learning to the NFSA. Some insufficiencies of log system, certain lacks of compliance with emergency procedures and some inconsistencies in crisis communication were reported. Following a broad evaluation process, the NFSA has carried out comprehensive revisions of contingency plans and procedures, conveyed the exercise learnings into an ongoing planning for reorganization, and has identified goals and methods for contingency training.

Practical implications
– Scenario, organization, methods for evaluation and assessments of learning effect may be applicable for similar organizations.

Originality/value
– This was the largest foodborne outbreak exercise ever conducted in Norway and among the few ones ever reported in scientific journals.
