Psychological identification with job: a leadership-OCB mediator
Authors: Dartey-Baah Kwasi , Addo Seth Ayisi 
Published: December 2018

Purpose
This study aims to examine influence of transformational and transactional leadership styles on employees’ organisational citizenship behaviours (OCBs), as well as the mediating role of job involvement in the Ghanaian hospitality industry.

Design/methodology/approach
Data were gathered from 258 employees in some selected hotels and restaurants in the Greater Accra Region of Ghana through a survey and analysed using covariance-based structural equation modelling.

Findings
The results indicated that both leadership styles influenced employees’ OCBs positively. Furthermore, job involvement positively influenced OCB and mediated between transformational leadership and OCB but not between transactional leadership and employees’ OCBs.

Practical implications
The study reaffirms the importance of employees’ OCBs and recommends that hotels and restaurants must encourage their supervisors to exhibit more transformational leadership behaviours (motivational, inspirational and visionary behaviours), as well as a combination of transformational and transactional leadership behaviours which can influence their employees to go beyond formal requirements, and get more involved in their jobs to the benefit of the organisations.

Originality/value
This study reveals the extent to which internal motivations of employees, specifically their job involvement, causes their extra-role behaviours and influences the leaders–OCB relationships from a developing country perspective.
A typology of market-seeking investments: Swedish firms in China
Authors: Jansson Hans , Söderman Sten 
Published: December 2018

Purpose
Regarding globalization trends, it is essential for multinational corporations (MNCs) to operate in China if they are to succeed in the international business environment. It is therefore vital to study how those MNCs investing in China have fared. The purpose of this paper is to devise a robust conceptual framework for the evolvement of market-seeking investments in emerging markets.

Design/methodology/approach
The typology is based on a network approach to internationalization processes, where a case study is made of Swedish MNCs’ experience of the Chinese market.

Findings
The case study contributes to the mostly static foreign direct investment (FDI) theory as well as the entry mode approach, both of which have paid little attention to the FDI carried out by MNCs in emerging markets 5–15 years after initial entry.

Originality/value
The case study also contributes to the mostly static FDI theory as well as the entry mode approach, both of which have paid little attention to the various types of FDI carried out by MNCs in emerging markets 5–15 years after initial entry.
Analyzing street crimes in Kobe city using PRISM
Authors: Kagawa Takuhiro , Saiki Sachio , Nakamura Masahide 
Published: December 2018

Purpose
In a previous research, the authors proposed a security information service, called Personalized Real-time Information with Security Map (PRISM), which personalizes the incident information based on living area of individual users. The purpose of this paper is to extend PRISM to conduct sophisticated analysis of street crimes. The extended features enable to look back on past incident information and perform statistical analysis.

Design/methodology/approach
To analyze street crimes around living area in more detail, the authors add three new features to PRISM: showing a past heat map, showing a heat map focused on specified type of incidents and showing statistics of incidents for every type. Using these features, the authors visualize the dynamic transition of street crimes in a specific area and the whole region within Kobe city. They also compare different districts by statistics of street crimes.

Findings
Dynamical visualization clarifies when, where and what kind of incident occurs frequently. Most incidents occurred along three train lines in Kobe city. Wild boars are only witnessed in a certain region. Statistics shows that the characteristics of street crimes is completely different depending on living area.

Originality/value
Previously, many studies have been conducted to clarify factors relevant to street crimes. However, these previous studies mainly focus on interesting regions as a whole, but do not consider individual’s living area. In this paper, the authors analyze street crimes according to users’ living area using personalized security information service PRISM.
A gradual approach for maximising user conversion without compromising experience with high visual intensity website elements
Authors: Jankowski Jarosław , Hamari Juho , Wątróbski Jarosław 
Published: December 2018

Purpose
The purpose of this paper is to develop and test a method that can gradually find a sweet spot between user experience and visual intensity of website elements to maximise user conversion with minimal adverse effect.

Design/methodology/approach
In the first phase of the study, the authors develop the method. In the second stage, the authors test and evaluate the method via an empirical study; also, an experiment was conducted within web interface with the gradual intensity of visual elements.

Findings
The findings reveal that the negative response grows faster than conversion when the visual intensity of the web interface is increased. However, a saturation point, where there is coexistence between maximum conversion and minimum negative response, can be found.

Practical implications
The findings imply that efforts to attract user attention should be pursued with increased caution and that a gradual approach presented in this study helps in finding a site-specific sweet spot for a level of visual intensity by incrementally adjusting the elements of the interface and tracking the changes in user behaviour.

Originality/value
Web marketing and advertising professionals often face the dilemma of determining the optimal level of visual intensity of interface element. Excessive use of marketing component and attention-grabbing visual elements can lead to an inferior user experience and consequent user churn due to growing intrusiveness. At the same time, too little visual intensity can fail to steer users. The present study provides a gradual approach which aids in finding a balance between user experience and visual intensity, maximising user conversion and, thus, providing a practical solution for the problem.
Wisdom extraction in knowledge-based information systems
Authors: Malik Zaki , Hashmi Khayyam , Najmi Erfan , Rezgui Abdelmounaam 
Published: December 2018

PurposeThis paper aims to provide a number of distinct approaches towards this goal, i.e. to translate the information contained in the repositories into knowledge. For centuries, humans have gathered and generated data to study the different phenomena around them. Consequently, there are a variety of information repositories available in many different fields of study. However, the ability to access, integrate and properly interpret the relevant data sets in these repositories has mainly been limited by their ever expanding volumes. The goal of translating the available data to knowledge, eventually leading to wisdom, requires an understanding of the relations, ordering and associations among the data sets.Design/methodology/approachWhile the existing information repositories are rich in content, there are no easy means of understanding the relevance or influence of the different facts contained therein. Therefore, the interest of the general populace in terms of prioritizing some data items (or facts) over others is usually lost. In this paper, the goal is to provide approaches for transforming the available facts in the information repositories to wisdom. The authors target the lack of order in the facts presented in the repositories to create a hierarchical distribution based on the common understanding, expectations, opinions and judgments of the different users.FindingsThe authors present multiple approaches to extract and order the facts related to each concept, using both automatic and semi-automatic methods. The experiments show that the results of these approaches are similar and very close to the instinctive ordering of facts by users.Originality/valueThe authors believe that the work presented in this paper, with some additions, can be a feasible step to convert the available knowledge to wisdom and a step towards the future of online information systems.
Disentangling rhetorical subarenas of public health crisis communication: A study of the 2014–2015 Ebola outbreak in the news media and social media in Sweden
Authors: Rodin Pavel , Ghersetti Marina , Odén Tomas 
Published: December 2018

AbstractDrawing on rhetorical arena theory, this study investigates the variations of content across communication channels (subarenas), guided by different media logics, during the 2014–2015 Ebola outbreak. Restricting the study to one country, Sweden, a content analysis was conducted of two national newspapers (in total 848 articles), their posts on branded Facebook pages (47) and user comments on these Facebook posts (1,661). Some conclusions to be made are, that content differed between subarenas, with Facebook news being more sensational and focused on human interest stories, and Facebook comments to a greater extent related to other current socio‐political issues. Also, news media were more alarmist than Facebook comments, although alarmism declined on all subarenas as the danger became more tangible.

Published: December 2018

BackgroundPD‐L1 expression in tumor cells has been associated with the efficacy of immune checkpoint inhibitors in non‐small cell lung cancer (NSCLC). The aim of this study was to explore correlations between smoking, genetic profiles, patient outcomes, and PD‐L1 expression in NSCLC.MethodsPD‐L1 expression was evaluated in 241 surgically resected specimens by immunostaining and 50% was set as the cutoff value.ResultsOf the 241 tumors analyzed, a PD‐L1 tumor proportion score (TPS) of ≥ 50% was detected in 35 cases (14.5%) and a TPS of < 50% in 206 cases (85.5%). A PD‐L1 TPS ≥ 50% was significantly associated with smoking and EGFR wild‐type status (P < 0.001 and P = 0.039, respectively). Detailed assessment of smoking variables showed that total smoking duration was a predictor of a PD‐L1 TPS ≥ 50% (P = 0.001). Univariate and multivariate survival analyses revealed that patients with a PD‐L1 TPS ≥ 50% had poorer disease‐free and overall survival than those with a PD‐L1 TPS < 50% (P = 0.001 and P < 0.001, respectively).ConclusionThe incidence of a PD‐L1 TPS ≥ 50% was significantly higher in smoking and EGFR wild‐type NSCLC patients, particularly in long‐term smokers. A PD‐L1 TPS of ≥ 50% was an independent adverse prognostic factor for survival in patients with NSCLC.

Published: December 2018

AbstractBackground and aimsMortality from alcohol‐attributable causes is patterned by income. We study the income trajectories 17–19 years prior to death in order to determine: (1) whether income levels and trajectories differ between those who die of alcohol‐attributable causes, survivors with similar socio‐demographic characteristics, all survivors and those dying of other causes; (2) whether the income trajectories of these groups differ by education; and (3) whether there are differences in income trajectories between Finland and Sweden—two countries with differing levels of alcohol‐attributable mortality but similar welfare‐provision systems.DesignRetrospective cohort study using individual‐level longitudinal register data including information on income, cause of death and socio‐economic status.SettingFinland and Sweden.ParticipantsThe subjects comprised an 11% sample of the Finnish population in 2006–07 and the total population of Sweden aged 45–64 years in 2007–08.MeasurementsMedian household income trajectories by educational group were calculated by cause of death and population alive during the respective years. Additionally, propensity score matching was used to match the surviving population to those dying from alcohol‐attributable causes with regard to socio‐demographic characteristics.FindingsThe median income 17–19 years prior to death from alcohol‐attributable causes was 92% (Finland) and 91% (Sweden) of survivor income: 1 year prior to death, the respective figures were 47% and 57%. The trajectories differed substantially. Those dying of alcohol‐attributable causes had lower and decreasing incomes for substantially longer periods than survivors and people dying from other causes. These differences were more modest among the highly educated individuals. The baseline socio‐demographic characteristics of those dying of alcohol causes did not explain the different trajectories.ConclusionsIn Finland and Sweden, income appears to decline substantially before alcohol‐attributable death. Highly educated individuals may be able to buffer the negative effects of extensive alcohol use on their income level. Income trajectories are similar in Finland and Sweden, despite marked differences in the level of alcohol‐attributable mortality.

Ikigai, one of the indices of well‐being, tends to decline with age because resources relating to ikigai decline. However, there are individual differences in this decline. This study tested for maintenance of ikigai among Japanese elderly, using a longitudinal study investigating the moderating role of social capital on the effects of changes in human capital on ikigai. We conducted a panel survey targeting 1,068 people (M age = 73.01 years) in 2013, and 686 people in 2017. The variables were ikigai, changes in human capital (self‐rated financial status, physical health) and social capital (social networks, trust in others), educational level, and control variables. Multiple regression analyses revealed the interaction effects of changes in physical health and changes in social networks (strong ties, weak ties) on follow‐up ikigai. Post hoc analyses indicated that declines in physical health predicted declines in ikigai among those whose social networks (strong ties and weak ties) had declined in the 4‐year study, but these relationships were not significant among those whose social networks had increased. The results suggest that older adults can weaken the adverse effect of a decline in human capital on ikigai by maintaining or increasing social networks.

Published: December 2018

AbstractAimChildren and adolescents with end‐stage renal disease face a high morbidity and mortality. Palliative care provides a multidisciplinary approach to reduce disease burden and improve quality of life. This study evaluated concepts and current structures of palliative care from the perspective of a multidisciplinary paediatric nephrology team including physicians, nurses and psychosocial health professionals.MethodsEvaluation was done by an online survey sent to the members of the German Society of Nephrology and to the nurse managers of German paediatric dialysis centres between April 9, 2018 and May 31, 2018.ResultsOut of the 52 respondents, 54% were physicians, 21% nurses and 25% psychosocial health professionals. The quality of actual palliative care service was rated as moderate (3.3 on a scale from one to six). Specialised palliative care teams (54%) and the caring paediatric nephrologist (50%) were considered as primarily responsible for palliative care. Two thirds wished for training in palliative care. In only 15% of the respondents’ centres, palliative care specialisation existed.ConclusionPalliative care structures in paediatric nephrology were not sufficient in the view of the multidisciplinary healthcare team. Therefore, efforts should be taken to integrate palliative care into the routine treatment of children and adolescents with chronic kidney diseases.
Practice variation among Dutch paediatricians in palivizumab prescription rates: the importance of parental counselling approach

Published: December 2018

AbstractAimTo investigate differences in palivizumab prescription rates between Dutch paediatricians, and the role of parent counselling in this practice variation.MethodsA retrospective chart review of premature infants <32 weeks of gestation, aged less than six months at the start of the winter season, born between January 2012 and July 2014, in three secondary hospital‐based paediatric practices in the Netherlands.ResultsWe included 208 patients, 133 (64%) of whom received palivizumab. Prescription rates varied considerably between the three hospitals: 8% (6/64), 89% (32/36) and 99% (97/98). A noticeable difference in the way parents were counselled about palivizumab was the use of the number needed to treat (NNT). In the hospital with the lowest prescription rate (8%), an NNT of 20 to prevent one hospitalisation was explicitly discussed with parents. Bronchiolitis‐related hospital admissions occurred in 11.3% of patients receiving palivizumab compared to 20.0% in nonimmunised infants (p = 0.086).ConclusionConsiderable practice variation exists among Dutch paediatricians regarding palivizumab prescription rates. The counselling method seems to play an important role. Presenting palivizumab prophylaxis as a preference‐sensitive decision, combined with the explicit use and explanation of an NNT, leads many parents to refrain from respiratory syncytial virus immunisation.

Published: December 2018

AbstractAimTo update our meta‐analysis on neurodevelopmental disability rates in children born at 22–25 weeks gestation. The main outcome measure was rates of neurodevelopmental disability in survivors at age 4–10 years.MethodsWe used a peer‐reviewed electronic and grey search to identify articles. Two authors independently reviewed cohorts published after May 2012 with: born ≥1995 in a developed nation; assessed at 4–10 years; prospective; >65% follow‐up; definitions for neurodevelopmental disability as per the EPICure cohort; results reported by gestation. We contacted authors for clarification. Random effects meta‐analysis was used to estimate pooled proportions of neurodevelopmental disability. Within each study, the absolute change in proportions with each week was estimated and then pooled.ResultsWe reviewed 3980 records; 21 articles were assessed and six were included. With the previous 9 cohorts, the meta‐analysis now contains 15. Rates of moderate‐to‐severe neurodevelopmental disability were as follows: 42% (95% CI 23,64%; I2 0%) at 22; 41% (95% CI 31,52%; I2 20%) at 23; 32% (95% CI 25,39%; I2 45%) at 24; 23% (95% CI 18,29%; I2 60%) at 25 weeks. The analysis shows a significant decrease in risk of moderate‐to‐severe neurodevelopmental disability between each week (8.1% (95% CI −11.8, −4.5%); I2 0%; p < 0.001).ConclusionPhysicians can use this high‐quality data to support parents during decision‐making.

Published: December 2018

AbstractLittle empirical research has examined the effects of case characteristics on high‐quality teamwork within family meetings in child welfare. We attempted to fill this gap using 497 child welfare cases in a Midwestern state in the United States. We found that overall teamwork was negatively associated with domestic violence, frequent placement moves, and a permanency plan of adoption, whereas teamwork was positively associated with the length of involvement in the child welfare system. We also examined the relationships between the case characteristics and two components of teamwork. The results showed that domestic violence and the length of the involvement were equally significant factors for both team formation and functioning. The permanency plan of adoption was a significant factor for team formation, but not for team functioning. Finally, family voices and frequent team meetings appeared to be stronger factors for improving both team formation and functioning. The results suggest that families in the child welfare system have different experiences in forming and functioning high‐quality family team meetings. Therefore, it is necessary to customize specific processes and strategies to promote teamwork depending on the child and family's characteristics and situations.

AbstractAimAnastomotic leakage (AL) is often identified 7–10 days after colorectal surgery. However, in retrospect, abnormalities may be evident much earlier. This study aims to identify the clinical time point when AL occurs.MethodThis is a retrospective case‐matched cohort comparison study, assessing patients undergoing left‐sided colorectal resection between 2006 and 2015 at a specialist colorectal unit. Patients who developed AL (LEAK) were case‐matched to two CONTROL patients by procedure, gender, laparoscopic modality and diverting stoma. Case note review allowed the collection of basic observation data and blood tests (leukocyte count, C‐reactive protein, bilirubin, alanine transaminase, creatinine) up to postoperative day (POD) 4. The cohorts were compared, with the main outcome measure being changes in basic observation data.ResultsOf 554 patients, 49 developed AL. These were matched to 98 CONTROL patients. Notes were available for 105 patients (32 LEAK/73 CONTROL). Groups were similar in demographics, tumour or nodal status, preoperative radiotherapy, intra‐operative air‐leak integrity and drain usage. AL was detected clinically at a median of 7.5 days postoperatively. There was a significantly increased heart rate by the evening on POD 1 in LEAK patients (82.8 ± 14.2/min vs 75.1 ± 12.7/min, P = 0.0081) which persisted for the rest of the study. By POD 3, there was a significant increase in respiratory rate (18.0 ± 4.2/min vs 16.5 ± 1.3/min, P = 0.0069) and temperature (37.0 ± 0.4C vs 36.7 ± 0.3C, P = 0.0006) in LEAK patients. C‐reactive protein was significantly higher in LEAK patients from POD 2 (165 ± 95 mg/l vs 121 ± 75 mg/l, P = 0.023).ConclusionsPhysiological and biochemical changes associated with AL happen very early postoperatively, suggesting that AL may occur within 36 h after surgery, despite much later clinical detection.
