Investigating human and technological requirements for successful implementation of a BIM-based mobile augmented reality environment in facility management practices
Authors: Gheisari Masoud , Irizarry Javier 
Published: January 2016

Purpose
– With the facility management industry increasingly adopting building information modeling (BIM) technologies, there is a need to investigate where this industry stands in its application. Moreover, studies on efficient and cost-effective solutions to integrate BIM and mobile augmented reality (MAR) present an environment where facility managers can experience an intuitive natural interaction with their mobile interfaces to efficiently access needed information. The industry’s view on this new approach of accessing information from BIM models should also be investigated, and its feedback should be considered for future phases of this avenue of research.

Design/methodology/approach
– This paper explores not only how BIM can be beneficial to facility management practitioners, but also how its integration with MAR and making the data accessible through handheld mobile devices can enhance current facility management practices. An online survey was conducted to assess professional facility managers’ characteristics, technology use and working environment as well as the current status of BIM application in their practices. An online video scenario has also been used to illustrate to facility managers how an ideal BIM-MAR-integrated environment could provide them with mobile access to their required information. Facility managers’ feedback on usability, applicability and challenges of such environment has also been investigated through a follow-up survey.

Findings
– With this paper, industry practitioners as well as academic researchers will be able to understand the current status of BIM and mobile computing application in facility management along with the benefits and challenges of implementing these technologies in an augmented reality (AR) environment.

Originality/value
– Understanding facility managers’ requirements, characteristics and the way they do their tasks would be of great value for development of tools or systems that would facilitate their practices.
Future of supply chain planning: closing the gaps between practice and promise
Authors: Jonsson Patrik , Holmström Jan 
Published: January 2016

Purpose
– The purpose of this paper is to develop a research agenda for supply chain planning (SCP) relevant for practice.

Design/methodology/approach
– The authors critically evaluate academic literature on SCP in order to understand how problems are addressed in their particular context, what the outcomes are, and the mechanisms producing the observed outcomes. Four categories of SCP are studied: sales and operations planning (S
&
OP), supply chain master planning, supply chain materials management, and collaborative materials management. The authors introduce the concept of enabling mechanisms to identify specific innovations in materials management and production management that can facilitate the future improvement of SCP.

Findings
– The critical evaluation of current SCP theory presents very limited results that are of practical relevance. SCP is not presented as an intervention and the results are not in a form that is actionable for practitioners. The body of literature is almost absent in addressing problems according to context, it presents limited evidence of intended outcomes, and it fails to identify unintended outcomes. As a consequence, research is unable to bolster theoretical understandings of how outcomes – both intended and unintended – are achieved. In the forward-looking research agenda the authors leverage the understanding of the enabling mechanisms in order to propose research to make mature S
&
OP and novel types of SCP implementable.

Research limitations/implications
– The paper is an example of a structured approach to developing a research agenda that is relevant to practice and can be used more widely in logistics and supply chain management.

Practical implications
– This paper presents a research agenda to close the gap between practice and promise in SCP.

Originality/value
– The authors operationalize what constitutes practical relevance for an established field of research.
The extended enterprise: a decade later
Authors: Spekman Robert , Davis Edward W 
Published: January 2016

Purpose– The purpose of this paper is to review the state of the art in extended enterprise (EE) thinking.Design/methodology/approach– The approach used the 2004 book,The Extended Enterprise, as the jumping-off point to review the literature and better define the EE. What was once projected as depicting the future state of supply chain management is now shaping the way in which organizations interact with their customers and suppliers. New issues in this arena include considerations of risk, knowledge sharing, and supply chain performance. The authors review these new developments, describe how they might affect the collaborative supply chain, and posit future trends.Findings– The major theme from this research is that EE thinking is emerging among global companies as a primary way in which firms now compete. The term “Collaborative supply chains” appears, in some circles, to replace the term “EE.” Yet the principles and tenets delineated in the term “EE” are captured in “collaborative supply chains.” The authors find that the EE concept is distinct from other supply chains or subcontracting relationships in that firms are linked as learning organizations. Also, the authors have noted barriers to collaboration such as an unwillingness to share information, lack of trust, perceptions of lack of mutuality and symmetry, and mistrust about the fairness of benefits, costs, and risk sharing.Research limitations/implications– The limitations of this research could be a function of the papers reviewed since this review was not intended to be exhaustive but merely illustrative of the extant research. Nonetheless, the conclusions from the focus on risk, knowledge sharing, and performance hold strong implications for more collaborative relations among supply chain partners.Originality/value– Given the importance of supply chain partnerships, this research adds perspective for those firms that are reluctant to engage in such collaborative partnerships. This review contributes to extended enterprise thinking and is therefore insightful for both academics and practitioners.
Search engines crawling process optimization: a webserver approach
Authors: Zineddine Mhamed 
Published: January 2016

Purpose
– The purpose of this paper is to decrease the traffic created by search engines’ crawlers and solve the deep web problem using an innovative approach.

Design/methodology/approach
– A new algorithm was formulated based on best existing algorithms to optimize the existing traffic caused by web crawlers, which is approximately 40 percent of all networking traffic. The crux of this approach is that web servers monitor and log changes and communicate them as an XML file to search engines. The XML file includes the information necessary to generate refreshed pages from existing ones and reference new pages that need to be crawled. Furthermore, the XML file is compressed to decrease its size to the minimum required.

Findings
– The results of this study have shown that the traffic caused by search engines’ crawlers might be reduced on average by 84 percent when it comes to text content. However, binary content faces many challenges and new algorithms have to be developed to overcome these issues. The proposed approach will certainly mitigate the deep web issue. The XML files for each domain used by search engines might be used by web browsers to refresh their cache and therefore help reduce the traffic generated by normal users. This reduces users’ perceived latency and improves response time to http requests.

Research limitations/implications
– The study sheds light on the deficiencies and weaknesses of the algorithms monitoring changes and generating binary files. However, a substantial decrease of traffic is achieved for text-based web content.

Practical implications
– The findings of this research can be adopted by web server software and browsers’ developers and search engine companies to reduce the internet traffic caused by crawlers and cut costs.

Originality/value
– The exponential growth of web content and other internet-based services such as cloud computing, and social networks has been causing contention on available bandwidth of the internet network. This research provides a much needed approach to keeping traffic in check.
Socio-economic factors determining the way e-tourism is used in European Union member states
Authors: Szopiński Tomasz , Staniewski Marcin Waldemar 
Published: January 2016

Purpose
– The purpose of this paper is to test the frequency of the use of e-tourism by consumers/internet users of various European Union member states and to identify the socio-economic variables that determine this frequency.

Design/methodology/approach
– The secondary data regarding the use of e-tourism services in 28 European Union member states were used for analysis. Relationships between variables and the frequency of the use of e-tourism services by consumers in 28 countries in Europe were analyzed. For each of the 32 benchmarked countries, a representative sample of internet users was surveyed via local online panels. Also CATI approach was used in one country.

Findings
– The authors of this study identify a statistically significant relationship between the frequency of the use of e-tourism by internet users and their country of origin. Statistically significant relationships between the frequency of using e-tourism and socio-economic variables, such as age, sex, education level, occupation, and professional position, are also identified.

Practical implications
– The findings of this study can provide tour operators with useful suggestions on how to extend the utility of internet (e-commerce) in order to develop their business, get more customers and improve their profitability. Simultaneously, these results may contribute to enhancing competitiveness of the whole European Union and increasing its gross domestic product.

Originality/value
– With the worldwide rapid growth of internet (and e-commerce) many benefits can be reach by tourism sector especially in the growing competition. The paper is unique because it shows data collected from almost 25,000 respondents and it presents a comparison of the use of e-tourism among citizens of 28 European Union member states.
Analyzing user perspective on the factors affecting use intention of mobile based transfer payment
Authors: Upadhyay Parijat , Jahanyan Saeed 
Published: January 2016

Purpose
– This study makes an integrated approach in identifying the factors affecting usage intention of mobile-based payment services. Such services are being marketed aggressively by cellular service providers and are different from usual mobile-based banking. The study incorporates prominent factors like the technical characteristics, technology-specific characteristics, user-specific characteristics, and task-specific characteristics and others from published literature. The purpose of this paper is to highlight those factors which have significant impact on the adoption of such service so that the adoption rate can be increased.

Design/methodology/approach
– A nationwide primary survey was conducted using validated questionnaire requesting response for the factors obtained from published literature. In total, 196 respondents participated in the survey. Totally, 11 hypotheses were formulated and statistically tested for their significance in context to the study. Confirmatory study was on the significant factors and a model has been proposed.

Findings
– The study finds that factors like perceived usefulness, perceived ease of use, system quality, connectivity, discomfort, task-technology fit and structural assurance have significant impact on the usage intention of mobile money services whereas factors such as perceived monetary value, absorptive capacity and personal innovativeness have been found to be insignificant.

Originality/value
– There have been no studies conducted which reported mobile-based transfer payment adoption issues where-in the transfer mechanism is independent of formal banking. The findings would be beneficial for service providers of mobile-based payment services to understand their subscribers and roll out value added services.
Private public distinction of the target and the long run operating performance of acquirers
Authors: Shams Syed M. M. , Gunasekarage Abeyratna 
Published: January 2016

Purpose– The purpose of this study is to examine whether the acquirers of private targets outperform their peers that acquire public targets in the long run.Design/methodology/approach– Using two samples of acquirers of private and public targets, this paper analyses their short-run market performance and long-run operating performance. Univariate analyses and multiple regressions are used to analyse abnormal stock returns and abnormal cash flow performances of bidders.Findings– Acquirers of private targets earn significantly higher abnormal return than acquirers of public targets during the announcement period. Similarly, the long-run operating performance of acquirers of private targets is significantly higher than that of the acquirers of public targets. However, the performance difference between two groups is more pronounced when cash flows are scaled by the market value of acquirers.Originality/value– This is the first Australian study to examine whether the long-run operating performance of acquirers depends on the organisational form of the target acquired.
The long-run performance of the New Zealand stock markets: 1899-2013
Authors: Frijns Bart , Tourani-Rad Alireza 
Published: January 2016

Purpose
– The aim of this paper is to construct a historical index for the New Zealand stock markets going back to 1899. From these historical returns, the authors can extract the average capital gains and dividend yield. It also allows them to provide an estimate for the equity risk premium (ERP).

Design/methodology/approach
– The authors collect stock-level data (prices, dividends, etc.) from quote records that are kept at the National Library in Wellington. From the stock-level data, the authors compute a value-weighted market index over the period 1899-2013.

Findings
– Over the period 1899-2013, the arithmetic mean of equity returns is 10.82 per cent p.a., with a standard deviation of 20.09 per cent. The New Zealand equity market had 92 years of positive returns and 23 years of negative returns during the sample period. The 10-year government bond yield, over the entire period, has an arithmetic mean return of 5.75 per cent. The ERP, on average, is 5.07 per cent.

Originality/value
– The authors collect the longest available historical data series for the New Zealand equity market. They document statistical properties as well as the long-term ERP over the entire sample period of 115 years and several subperiods. The ERP is a key input in corporate/project valuation.
Ukrainians in the German Armed Forces During the Second World War
Authors: Khromeychuk Olesya 
Published: January 2016

AbstractDuring the Second World War large numbers of inhabitants of central, eastern and southern Europe joined the German Armed Forces. Among them were around 250,000 soldiers who identified themselves as Ukrainian. They served in the Wehrmacht, as well as the Waffen SS; a considerable number of them also served in the auxiliary police. They were motivated to join the German Armed Forces by a combination of different factors. This article aims to shed some light on the broad range of circumstances that facilitated the recruitment of thousands of Ukrainians to fight on the side of the Third Reich. It discusses several well‐known formations that were comprised of Ukrainians, such as the Nachtigall and Roland battalions and the Waffen SS ‘Galicia’ Division, as well as other units that have not been widely discussed in an academic context.

Published: January 2016

AbstractThe increase in energy demand due to economic and population growth necessitates the expansion of the Brazilian energy supply. Hydropower energy, a renewable energy source, arguably clean, presents an energy solution for many countries such as Brazil, with large hydric reservoirs, which help them reduce energy dependence on fossil and imported fuel sources. However, it must be emphasized that without careful planning, the creation of hydropower plants will cause severe social and environmental damage due to the large areas that need to be flooded for the implementation of these plants. The installation of hydropower plants floods vast forest areas, causing loss of biodiversity, displacement of native Brazilian people and riverside populations, and changes to the water acid levels and the natural course of rivers. To mitigate these effects, authorities must first conduct a study on installation possibilities and potential socio‐environmental consequences, to be interpreted and used by the agents involved. Aiming to analyze the social‐environmental impacts of the hydropower plants, this research seeks to investigate the capacity of mitigation of the negative effects of the implementation of the hydropower plants, specifically with regard to the Belo Monte plant, Brazil.

Authors: Zhao Kejia , Mei Jiandong , Hai Yang , Liu Chengwu , Ma Lin , Liu Lunxu 
Published: January 2016

AbstractA cross‐filed endotracheal intubation is usually applied to maintain single lung ventilation during both open and thoracoscopic tracheal resection and reconstruction. Herein, we report a case of thoracoscopic tracheal resection and reconstruction with interrupted ventilation via transoral endotracheal intubation in a patient with thoracic tracheal adenocarcinoma. Tracheal anastomosis was accomplished using a running suture with a 3‐0 Prolene stitch.
Persistent postsurgical pain after video‐assisted thoracic surgery – an observational study
Authors: Wildgaard K. , Ringsted T. K. , Hansen H. J. , Petersen R. H. , Kehlet H. 
Published: January 2016

BackgroundThe risk of persistent postsurgical pain (PPP) and subsequent pain‐related functional impairment may potentially be reduced by video‐assisted thoracic surgery (VATS) compared to thoracotomy. The aim of the study was therefore to assess in detail the incidence and consequences on activities of daily living of PPP after VATS.MethodsUsing a prospective observational design, 47 patients undergoing VATS completed both preoperative, early postoperative and 3 months follow‐up. Preoperative pain, pain characteristics, psychological factors, pain‐related functional impairment and quantitative sensory testing (QST) including nociceptive thresholds were compared with postoperative data.ResultsOnly five (11%) patients developed PPP with NRS > 3 originating from the surgical area. However, about 30% of patients still reported some pain‐related functional impairment from the surgical area within four well‐defined domains of everyday activities. Psychological and sensory thermal tests did not predict persistent postoperative pain, except preoperative pin‐prick sensitivity was higher in patients with PPP. Postoperative pain 7 days after surgery was significantly higher in PPP patients. Preoperative pain originating from remote areas did not predict PPP.ConclusionThe incidence of PPP, nerve damage (based on QST) and pain‐related functional impairment following VATS was lower than reported following thoracotomy. No psychological or other factors predicted PPP. These findings call for further large‐scale studies to support VATS to decrease PPP.
Pressure‐dependent changes in haematocrit and plasma volume during anaesthesia, a randomised clinical trial
Authors: Damén T. , Reinsfelt B. , Redfors B. , Nygren A. 
Published: January 2016

BackgroundInduction of general anaesthesia has been shown to cause haemodilution and an increase in plasma volume. The aim of this study was to evaluate whether prevention of hypotension during anaesthesia induction could avoid haemodilution.MethodsTwenty‐four cardiac surgery patients, 66 ± 10 years, were randomised to receive either norepinephrine in a dose needed to maintain mean arterial blood pressure (MAP) at pre‐anaesthesia levels after induction or to a control group that received vasopressor if MAP decreased below 60 mmHg. No fluids were infused. Changes in plasma volume were calculated with standard formula: 100 × (Hctpre/Hctpost − 1)/(1 − Hctpre). Arterial blood gas was analysed every 10 minutes and non‐invasive continuous haemoglobin (SpHb) was continuously measured.ResultsPre‐anaesthesia MAP was 98 ± 7 mmHg. Ten minutes after anaesthesia induction, the haematocrit decreased by 5.0 ± 2.5% in the control group compared with 1.2 ± 1.4% in the intervention group, which corresponds to increases in plasma volume by 310 ml and 85 ml respectively. MAP decreased to 69 ± 15 mmHg compared to 92 ± 10 mmHg in the intervention group. The difference maintained throughout the 70 min intervention period. The change in haemoglobin level measured by blood gas analysis could not be detected by SpHb measurement. The mean bias between the SpHb and blood gas haemoglobin was 15 g/l.ConclusionDuring anaesthesia induction, haematocrit decreases and plasma volume increases early and parallel to a decrease in blood pressure. This autotransfusion is blunted when blood pressure is maintained at pre‐induction levels with norepinephrine.

Published: January 2016

AbstractAimItalian national guidelines on pain management were published in 2010, but there is little information on how effective pain management is in paediatric emergency care, with other countries reporting poor levels. Using headache as an indicator, we described pain assessment in Italian emergency departments and identified predictors of algometric scale use.MethodsAll Italian paediatric and maternal and child hospitals participated, plus four general hospitals. Data on all children aged 4–14 years admitted during a one‐month period with headache as their chief complaint were abstracted from clinical records. Multivariable analyses identified predictors of algometric assessment, taking into account the cluster study design.ResultsWe studied 470 admissions. During triage, pain was assessed using a standardised scale (41.5%), informally (15.5%) or was not recorded (42.9%). Only 32.1% of the children received analgesia in the emergency department. The odds ratios for predictors of algometric assessment were non‐Italian nationality (3.6), prehospital medication (1.8), admission to a research hospital (7.3) and a more favourable nurses‐to‐admissions ratio of 10.8 for the highest versus lowest tertile.ConclusionDespite national guidelines, paediatric pain assessment in Italian emergency care was suboptimal. Hospital variables appeared to be stronger predictors of adequate assessment than patient characteristics.
