From camps to social integration? Social housing interventions for asylum seekers in Greece
Authors: Kourachanis Nikos 
Published: December 2018

PurposeThis paper offers an empirical study of the Emergency Support to Integration and Accommodation (ESTIA) programme, as the policy initiative for the provision of housing and social integration for asylum seekers over the last few years in Greece. Greece is a country that is geographically situated on the southern external borders of Europe and has been experiencing a rise in refugee flows since 2015. At a first glance, it seems that ESTIA’s central aim is social integration. The purpose of this paper is to investigate whether the design and implementation framework of ESTIA essentially promotes the goal of social integration or whether it is merely a gesture that has no real effect.Design/methodology/approachThe field research focussed on an evaluation of the ESTIA programme on the basis of its impact on the social integration of its beneficiaries. This was attempted by examining the attitudes and perceptions of key stakeholders during its design and implementation stages. In order to examine these dimensions, qualitative research methods were developed. In particular, in-depth interviews were conducted with key informants involved in the design and implementation processes of ESTIA.FindingsSocial integration is something much more than providing permanent shelters to asylum seekers. ESTIA has been designed and implemented with a view to providing better temporary housing conditions for its beneficiaries. The rest of the range of actions for their social actions was left to voluntary actions by the implementing agencies, without offering them any financial support – a fact that suggests that the use of the term “social integration” in relation to this programme is disingenuous. Such an intervention does not aim at significant social integration but, primarily, the temporary management of extreme impoverishment. ESTIA can, therefore, be added to the scientific literature as yet another case study where the complex concept of social integration is misused by the EU and European states to legitimise the policies of repression and control of refugee populations.Originality/valueThis is the first field research that examines the design and implementation framework of ESTIA, the most important programme for the social integration of asylum seekers in Greece. The presentation of research findings is expected to make a significant contribution to the improvement of many aspects of the design and implementation framework of ESTIA.

Published: December 2018

PurposeThe purpose of this paper is to explore the factors that enable work engagement to develop when asynchronous communication is used in virtual team (VT) projects.Design/methodology/approachUsing a qualitative approach, a longitudinal study of an eight-month long VT project was carried out. Data collected included an extensive e-mail archive, project documentation, observation of team meetings and interviews with project members and leaders.FindingsThe findings show that VT leaders can actively promote work engagement through the effective use of resources along with appropriate practices that foster its development. They can also sustain and nourish work engagement throughout the different phases of the VT lifecycle project.Research limitations/implicationsThe study has examined work engagement in asynchronous mediated settings. Future work should involve studying the effect of synchronous communications on work engagement within VTs.Practical implicationsOrganizations that are interested in promoting effective virtual work practices need to train VT managers on how to keep VT members engaged throughout the various phases of the VT project.Social implicationsIt is posited that developing work engagement is not a one-off practice, but instead, requires ongoing effort that should be evident and supported across the different phases of the VT lifecycle.Originality/valueThis paper forwards an important debate on work engagement in alternative, non-permanent, work settings.
Enhancing client-agency relationship quality in the advertising industry – an application of project management
Authors: Levin Elizabeth , Quach Thu Nguyen , Thaichon Park 
Published: December 2018

PurposeThis paper aims to determine the dimensions of service quality of advertising agencies and their effects on relationship quality between an advertising agency and their clients through the social and economic exchange.Design/methodology/approachThe intention was to target firms which use the services of an advertising or marketing solutions agency; hence, participants were recruited from a business database service providing details for key decision makers in Australia and New Zealand. An online survey was used in this study.FindingsCreative competence, project management processes and project outcome influenced relationship quality through value and interpersonal relationships. However, only creativity had a significant direct relationship with relationship quality.Practical implicationsAlthough creativity plays a major role in relationship development, agencies must have efficient and effective project management processes in place to ensure successful project completion within timeline and budget to be able to maintain ongoing relationships with their clients.Originality/valueThe research draws upon literature from three key disciplines, service quality, relationship marketing and project management, to address the gaps in the current literature related to customer relationship management in the B2B client–agency context.
Student performance is linked to connecting effectively with teachers
Authors: Gilbert Michael 
Published: December 2018

Purpose
The purpose of this paper is to examine student performance on both criterion- and norm-referenced measures, linked with teacher and student communication orientations.

Design/methodology/approach
The study used a pre-post design. During the pre-study phase, teachers underwent three days of intensive training in the Process Education Model®. In total, 21 middle and high school teachers at an independent school were the subject group. Each teacher identified ten students, five of whom they classified as “easy to communicate with” and five others whom they classified as “difficult to communicate with.” Approximately, 200 students participated in the study. Teachers and students provided communication preferences via the Kahler Personality Pattern Inventory® (1996). Performance data were gleaned from student grade point averages (GPAs) and grade-appropriate versions of ACT instruments.

Findings
The PPI reveals, in part, perceptual preferences in an assessing matrix. Intrinsic and extrinsic orientations were one set of distinctions. Most (more than 85 percent) of the teachers had intrinsic orientations, compared with 63 percent of the “easy” students and 47 percent of the “difficult” students. Both GPA and ACT comparisons were significantly different (p<0.001) on both pre- and post-measures, with the easy students outstripping their difficult counterparts. No significant differences were observed on the ACT Aspire, taken by students in grades 6–9.

Research limitations/implications
The study was conducted at one site.

Practical implications
Student performance appears to be linked with connecting with teachers’ preferred delivery and communication styles. The more like their teachers the students are, the better their performance. Reinforcing new knowledge and skills was recognized as an important component of training.

Originality/value
If connecting better with students is tied with performance, teachers who learn how to shift their delivery methods may foster better outcomes. Also, attention should be paid on how distress may impact teacher performance, especially as they interact with students whose communication preferences may differ from theirs.
Influence of part’s geometrical properties on shrinkage and laser heat affected zone size at selective laser sintering
Authors: Brajlih Tomaz , Kostevsek Urska , Drstvensek Igor 
Published: December 2018

Purpose
One of the main problems of selective laser sintering (SLS) manufacturing process is the dimensional accuracy of products. Main causes of dimensional deviations are material shrinkage and size of laser heat affected zone (LHAZ). This paper aims to present a new method of adapting SLS manufacturing shrinkage and LHAZ compensation parameters to the geometrical characteristics of processed parts to improve their accuracy.

Design/methodology/approach
The first part of this work presents a hypothesis asserting that the shrinkage and the LHAZ size depend on geometrical properties of products. A method that defines geometrical properties by numerical influence factors is described in the continuation. A multi-factorial experiment with adaptable test part is set up. Then, test builds are manufactured on an SLS machine and measured with a three-dimensional optical scanner. Afterwards, the results are analysed in relation to the presumed hypothesis.

Findings
The analysis of variance of multi-factorial experiment proves the hypothesis and the influence of the geometrical properties on the accuracy of the SLS manufacturing process. Afterwards, a part is manufactured with adapted values of compensation parameters and the archived accuracy is discussed.

Research limitations/implications
Presented research is limited on a single SLS material. Also, some numerical factors are directly linked to the build volume dimensions of the SLS machine that was used in the experiment. However, results can be generalised and some guidelines for shrinkage and LHAZ compensation method are presented. Also, some guidelines for future research are proposed.

Practical implications
Based on the presented results, it can be determined that using constant shrinkage and LHAZ values on an SLS machine will not yield the same results in terms of accuracy if the geometrical properties of parts change significantly.

Social implications
By correctly adapting compensation values, the overall achievable accuracy of the SLS process can be achieved, enabling a more reliable production of mass-customised end-user parts such as customised medical accessories and devices for example.

Originality/value
A similar method of numerically describing geometrical properties of part in regard to SLS and directly adapting shrinkage and LHAZ compensation values to them for every individual build has not yet been proposed.

Published: December 2018

AbstractPustulotic arthro‐osteitis, occasionally complicated with palmoplantar pustulosis, affects patients’ activities of daily living. Granulocyte and monocyte adsorption apheresis selectively removes activated granulocytes and monocytes by means of extracorporeal circulation. Although the efficacy of granulocyte and monocyte adsorption apheresis in the treatment of generalized pustular psoriasis has been proved, very few reports have assessed its efficacy in the treatment of palmoplantar pustulosis and pustulotic arthro‐osteitis. Ten pustulotic arthro‐osteitis patients with five palmoplantar skin manifestations were treated with weekly granulocyte and monocyte adsorption apheresis over 5 weeks. Skin manifestations were assessed using palmoplantar pustulosis area and severity index, and joint symptoms were assessed using a visual analog scale of joint pain, tender joint count, swollen joint count and C‐reactive protein immediately before, after and at the 3‐month follow up of the five granulocyte and monocyte adsorption apheresis sessions. Two out of five patients with skin manifestations achieved more than 50% improvement in their score (remarkably improved). However, in two patients, deterioration was noted, in one of whom the skin manifestations remained unchanged at the 3‐month follow up. In five out of the 10 patients, the joint symptoms were assessed as better than improved at the 3‐month follow up. No deterioration was noted at the 3‐month follow up. In three patients, reduction or cessation of medication for arthralgia was possible. We concluded that granulocyte and monocyte adsorption apheresis is a therapeutic option to consider when pustulotic arthro‐osteitis is recalcitrant to conventional therapy.

Published: December 2018

SummaryCobamides (Cbas) are essential cofactors of reductive dehalogenases (RDases) in organohalide‐respiring bacteria (OHRB). Changes in the Cba structure can influence RDase function. Here, we report on the cofactor versatility or selectivity of Desulfitobacterium RDases produced either in the native organism or heterologously. The susceptibility of Desulfitobacterium hafniense strain DCB‐2 to guided Cba biosynthesis (i.e. incorporation of exogenous Cba lower ligand base precursors) was analysed. Exogenous benzimidazoles, azabenzimidazoles and 4,5‐dimethylimidazole were incorporated by the organism into Cbas. When the type of Cba changed, no effect on the turnover rate of the 3‐chloro‐4‐hydroxy‐phenylacetate‐converting enzyme RdhA6 and the 3,5‐dichlorophenol‐dehalogenating enzyme RdhA3 was observed. The impact of the amendment of Cba lower ligand precursors on RDase function was also investigated in Shimwellia blattae, the Cba producer used for the heterologous production of Desulfitobacterium RDases. The recombinant tetrachloroethene RDase (PceAY51) appeared to be non‐selective towards different Cbas. However, the functional production of the 1,2‐dichloroethane‐dihaloeliminating enzyme (DcaA) of Desulfitobacterium dichloroeliminans was completely prevented in cells producing 5,6‐dimethylbenzimidazolyl‐Cba, but substantially enhanced in cells that incorporated 5‐methoxybenzimidazole into the Cba cofactor. The results of the study indicate the utilization of a range of different Cbas by Desulfitobacterium RDases with selected representatives apparently preferring distinct Cbas.
Parallel likelihood calculation for phylogenetic comparative models: The SPLITT C++ library
Authors: Mitov Venelin , Stadler Tanja 
Published: December 2018

Abstract

Phylogenetic comparative models (PCMs) have been used to study macroevolutionary patterns, to characterize adaptive phenotypic landscapes, to quantify rates of evolution, to measure trait heritability, and to test various evolutionary hypotheses. A major obstacle to applying these models has been the complexity of evaluating their likelihood function. Recent works have shown that for many PCMs, the likelihood can be obtained in time proportional to the size of the tree based on post‐order tree traversal, also known as pruning. Despite this progress, inferring complex multi‐trait PCMs on large trees remains a time‐intensive task. Here, we study parallelizing the pruning algorithm as a generic technique for speeding‐up PCM‐inference.

We implement several parallel traversal algorithms in the form of a generic C++ library for Serial and Parallel LIneage Traversal of Trees (SPLITT). Based on SPLITT, we provide examples of parallel likelihood evaluation for several popular PCMs, ranging from a single‐trait Brownian motion model to complex multi‐trait Ornstein‐Uhlenbeck and mixed Gaussian phylogenetic models.

Using the phylogenetic Ornstein–Uhlenbeck mixed model (POUMM) as a showcase, we run benchmarks on up to 24 CPU cores, reporting up to an order of magnitude parallel speed‐up for the likelihood calculation on simulated balanced and unbalanced trees of up to 100,000 tips with up to 16 traits. Noticing that the parallel speed‐up depends on multiple factors, the SPLITT library is capable to automatically select the fastest traversal strategy for a given hardware, tree‐topology, and data. Combining SPLITT likelihood calculation with adaptive Metropolis sampling on real data, we show that the time for Bayesian POUMM inference on a tree of 10,000 tips can be reduced from several days to less than an hour.

We conclude that parallel pruning effectively accelerates the likelihood calculation and, thus, the statistical inference of Gaussian phylogenetic models. For time‐intensive Bayesian inferences, we recommend combining this technique with adaptive Metropolis sampling. Beyond Gaussian models, the parallel tree traversal can be applied to numerous other models, including discrete trait and birth–death population dynamics models. Currently, SPLITT supports multi‐core shared memory architectures, but can be extended to distributed memory architectures as well as graphical processing units.
Optic Disc Coloboma in children – prevalence, clinical characteristics and associated morbidity

Published: December 2018

AbstractPurposeThe aim of the study was to report prevalence, ocular outcome, neurological characteristics, cognitive and behavioural problems in children with optic disc coloboma (ODC).MethodsThis was a population‐based, cross‐sectional study of 31 children between 2 and 18 years of age diagnosed with ODC. The children were part of a larger cohort of 184 children with congenital optic disc malformations. Clinical ophthalmological examinations, neurological assessments, behavioural and developmental screening were performed.ResultsThe prevalence of ODC was 8.9/100 000 children. Of the 31 patients, 18 had unilateral ODC (p = 0.21). The best‐corrected visual acuity (BCVA) in the ODC eye ranged from blindness to 1.3 (median 0.3). BCVA was 0.82 in eyes with an isolated ODC (range 0.4–1.3) and 0.15 (range 0–0.5) in eyes with concurrent macular involvement (p < 0.0001). Nystagmus was observed more often in patients with bilateral ODC (9/13 versus 3/17, p = 0.004). Two patients had retinal detachment. Behavioural/psychological screening was performed in 21 patients with severe deficits identified in six cases. Intellectual disability was present in seven patients. Neurological dysfunction was diagnosed in 8/22 cases. All of the above children had already systemic diagnoses before the ODC diagnosis was made.ConclusionsODC was the second most common optic disc malformation in this cohort after optic nerve hypoplasia. The children had a wide range of ocular comorbidity. An isolated ODC without macular involvement was not associated with profound vision loss. The ability of screening in the regular child care centres to diagnose extraocular comorbidities was very good and referral to a paediatrician appears redundant in cases of normal development.

Published: December 2018

AbstractIntroductionA 50‐year‐old Japanese man presented with obstructive jaundice. We performed endoscopic retrograde biliary drainage before biliary decompression. CT showed a thickened gallbladder wall with low‐density areas and a 35‐mm gallstone; the stone was impacted in the gallbladder neck and cystic duct. The patient was therefore diagnosed with Mirizzi syndrome (type II or III) and scheduled for laparoscopic treatment. We performed subtotal cholecystectomy and intraoperative choledochoscopy because we recognized a fistula between the gallbladder and common bile duct preoperatively.Materials and Surgical TechniqueWe opened the ductus choledochus, and a choledochoscope was introduced under laparoscopic guidance. An electrohydraulic lithotripsy probe with irrigation was passed through the choledochoscope to extract the gallstone.DiscussionThis fragmentation technique is effective for impacted large stones observed in Mirizzi syndrome. Therefore, electrohydraulic lithotripsy with laparoscopy is effective in cases of difficult gallbladder access such as that that occurs in type II or III Mirizzi syndrome.

AbstractIntroductionSurgical techniques for Spiegel lobectomy remain technically difficult because of its deep anatomical location. Laparoscopic Spiegel lobectomy has not yet been standardized or widely reported. In the current study, we introduce technical improvements, including the liver hanging maneuver, to laparoscopic Spiegel lobectomy. Additionally, we demonstrate the safety and feasibility of this procedure.Materials and Surgical TechniqueWe performed consecutive laparoscopic Spiegel lobectomy on six patients: five with hepatocellular carcinoma and one with colorectal liver metastasis. As preparation before liver parenchymal resection, necessary and sufficient mobilization of the Spiegel lobe was performed. A few Glissonian pedicles of the Spiegel lobe were exposed from the hilar plate and divided to reduce the inflow to the Spiegel lobe. After that, vessel tape was used in the hanging maneuver. The tape was pulled forward to give the cutting plane moderate tension during liver parenchymal resection. Lifting this tape provided better exposure for determining the correct cutting plane during liver parenchymal transection. The median operation time was 207 min (range, 147–240 min) and the median intraoperative blood loss was 35 mL (range, 15–85 mL). There were no severe postoperative complications.DiscussionWe safely performed laparoscopic Spiegel lobectomy. To maintain a sufficient surgical view, especially during liver parenchymal resection, the hanging maneuver may be a useful technique. This single‐center investigation into standardized laparoscopic Spiegel lobectomy featuring improvements in technique showed potential for favorable results.
