Authors: Greige Frangieh Charbel , Khayr Yaacoub Hala 
Published: July 2017

PurposeThis study aims to provide a point of reference and another of guidance for future research on the topic of responsible leadership by exploring its challenges, outcomes and practices.Design/methodology/approachA systematic review of the literature, originally adopted from the medical sciences but also used in management and leadership studies, was conducted to integrate research in an organized, translucent and reproducible manner. The final sample of 46 empirical and conceptual studies were scientifically screened and synthesized.FindingsThe synthesis revealed that balancing stakeholder needs, personal characteristics and organizational structures are the main challenges against responsible leadership, whereas financial benefits, employees-related benefits and reputational gains among others are the main outcomes. Practices pinpointed, while scarce, are represented in nurturing a stakeholder culture, and engaging employee-related and human-resource-responsible functions.Originality/valueThis study contributes to the development of responsible leadership.
Servitization as reinforcement, not transformation
Authors: Salonen Anna , Saglam Onur , Hacklin Fredrik 
Published: July 2017

Purpose
The purpose of this paper is to explain why product-centric manufacturers utilize advanced services not as vehicles of transformation, but of reinforcement, to strengthen their established business model logic based on selling products and basic product-related services.

Design/methodology/approach
The empirical basis of this study relies on an in-depth case study of a globally operating manufacturer of industrial pumps and related services. The data includes 31 interviews conducted over several years of in-depth collaboration with the studied firm.

Findings
Product-centric manufacturers utilize advanced services as engagement platforms to facilitate the external and internal engagement of the actors and the resources controlled by them. Externally, advanced services facilitate access to customer decision makers and insights into their latent needs. Internally, advanced services help the manufacturer to more effectively leverage resources that reside within its different organizational units. Ultimately, in leveraging advanced services as engagement platforms, the manufacturer seeks to boost activities with the greatest immediate impact on its market performance: the sale of products and basic product-related services.

Practical implications
The study explains why managers should invest into development of advanced services even if such services contribute only marginally to the manufacturer’s direct revenues and profits.

Originality/value
This study contributes to development of an alternative explanation of servitization that departs from the current paradigmatic assumptions in the field.

Authors: Saedi Daryan Amir , Yahyai Mahmood 
Published: July 2017

Purpose
This paper aims to predicting the behavior of welded angle connections (moment-rotation-temperature) in fire using artificial neural network 10.

Design/methodology/approach
An artificial neural networking model is described to predict the moment-rotation response of semi-rigid beam-to-column joints at elevated temperature.

Findings
Data from 47 experimental fire tests and verified finite element model are used for training and testing and validating the neural network models. The model’s predicted values are compared with actual test results. The results indicate that the models can predict the moment-rotation-temperature behavior of semi-rigid beam-to-column joints with very high accuracy. The developed model can be modified easily to investigate other parameters that influence the performance of joints in fire.

Originality/value
The results indicate that the models can predict the moment-rotation-temperature behavior of semi-rigid beam-to-column joints with very high accuracy. The developed model can be modified easily to investigate other parameters that influence the performance of joints in fire.
Think outside: positive risk-taking with people living with dementia
Authors: Mapes Neil 
Published: July 2017

Purpose
The purpose of this paper is to share findings from the evaluation of dementia adventure (DA) holidays provided in 2016 and drawing on these data, to share reflections on positive risk-taking, which are inherent in outdoor activities, and consider the implications for research and practice with people with dementia.

Design/methodology/approach
Data are drawn from the 2016 internal evaluation report, using mixed methods design, of DA holidays independently reviewed by Dr Ruth Bartlett at the University of Southampton.

Findings
DA holidays are leading to a range of social, emotional and physical well-being outcomes, as well as wider benefits for the community of people with dementia, their family and carers.

Practical implications
Drawing on what positive risk-taking means for individuals, families and organisations, top ten considerations for positive risk taking outdoor activities are presented.

Originality/value
The number of organisations providing adventure experiences and holidays for people with dementia in the UK remains very low with just a handful of organisations. The impact and evaluation of these holidays is just emerging and whilst compelling needs replication, with larger sample sizes supported by clinical and scientific expertise to deepen our understanding of the impact of positive risk-taking outdoor activities. Additionally, there is a need for thinking and acting differently summarised by the phrase “THINK OUTSIDE” in developing a wide range of nature based positive risk-taking activities with people with dementia.
Decision-making dynamics between Spanish mothers, fathers and children
Authors: Carrero Isabel , Aleti Torgeir 
Published: July 2017

Purpose
The purpose of this paper is to investigate the roles of mothers, fathers and children in family decision-making (FDM) processes in families with different characteristics in terms of household structure, parents’ resources and family communication styles. As several structural changes regarding families have taken place within the last decades, there is a need to update the theories around FDM – in particular, regarding to the role of women and children.

Design/methodology/approach
A survey was distributed to 520 individuals in 183 families, where mothers, fathers and children above nine years living at home completed the survey.

Findings
The study demonstrates that the product category largely influences FDM dynamics, as well as housework division, parental characteristics and communication style. The study also reveals that structural changes may put more pressure on mothers. This pressure can partly be relieved if the family encourages children to become independent consumers rather than trying to control their consumption. Moreover, when fathers take a larger part in the housework, traditional gender roles become more fluid.

Social implications
For policymakers concerned with equality within the family, it may be a better approach to enable fathers to more actively participate in household chores than to try to change behaviour through information about equality.

Originality/value
This study extends the understanding of FDM in contemporary households by taking into account the views of all family members and produces a more complete picture of the decision-making dynamics within families.
Gender-based food stereotypes among Turkish university students
Authors: Basfirinci Cigdem , Cilingir Uk Zuhal 
Published: July 2017

Purpose
This study aims to investigate gendered meanings of food and its relationship with identity management for Turkish university students’ food practices and beliefs.

Design/methodology/approach
Methodologically, both qualitative and quantitative approaches were used in this study as a complementary way. Data were collected from a total of 711 university students.

Findings
Taken together, the findings strongly support gender-based food stereotypes as consistent with previous literature with some cultural variations. As another important finding, gendered associations of foods are stronger than those of non-alcoholic beverages among Turkish university students.

Originality/value
In terms of original contribution, this study not only provides valuable information about young consumers’food beliefs and practices in terms of gender-based stereotypes and identity management, but also enriches the current literature, specifically focusing on Turkey, which has a completely different cultural background as compared to Europe, the USA and the Far East. To the best of authors’knowledge, this is the very first study on this subject specifically focusing on Turkish consumers’ gift-buying behaviors through the internet channel.

AbstractThe complement pathway has potential contributions to both white (WM) and grey matter (GM) pathology in Multiple Sclerosis (MS). A quantitative assessment of complement involvement is lacking. Here we describe the use of Tissue MicroArray (TMA) methodology in conjunction with immunohistochemistry to investigate the localization of complement pathway proteins in progressive MS cortical GM and subcortical WM. Antibodies targeting complement proteins C1q, C3b, regulatory proteins C1 inhibitor (C1INH, complement receptor 1 (CR1), clusterin, factor H (FH) and the C5a anaphylatoxin receptor (C5aR) were utilised alongside standard markers of tissue pathology. All stained slides were digitised for quantitative analysis. We found that numbers of cells immunolabelled for HLA‐DR, GFAP, C5aR, C1q and C3b were increased in WM lesions (WML) and GM lesions (GML) compared to normal appearing WM (NAWM) and GM (NAGM), respectively. The complement regulators C1INH, CR1, FH and clusterin were more abundant in WM lesions, while the number of C1q+ neurons were increased and the number of C1INH+, clusterin+, FH+ and CR1+ neurons decreased in GM lesions. The number of complement component positive cells (C1q, C3b) correlated with complement regulator expression in WM, but there was no statistical association between complement activation and regulator expression in the GM. We conclude that TMA methodology and quantitative analysis provides evidence of complement dysregulation in MS GML, including an association of the numerical density of C1q+ cells with tissue lesions. Our work confirms that complement activation and dysregulation occur in all cases of progressive MS and suggest that complement may provide potential biomarkers of the disease.

Published: July 2017

Background and purposeInfection with the John Cunningham virus (JCV) is required for the development of progressive multifocal leukoencephalopathy, the feared complication of natalizumab treatment in multiple sclerosis patients. The JCV seroconversion rate seems higher in natalizumab treated patients than in the normal population, with an unknown cause.MethodsNatalizumab concentration was correlated to JCV antibody status and seroconversion in a large cohort of multiple sclerosis patients.ResultsOne hundred and thirty‐five patients were included. No correlation was found between natalizumab concentration and JCV status, JCV seroconversion or JCV index.ConclusionsHigher natalizumab concentrations do not explain the increased JCV seroconversion rate in natalizumab treated patients.
An investigation of the beneficial effects of adding carbon nanotubes to standard injection grout
Authors: Restuccia L. , Lopez A. , Ferro G.A. , Liberatore D. , Tulliani J.M. 
Published: July 2017

AbstractMortar grouting is often used in masonry constructions to mitigate structural decay and repair damage by filling cracks and voids, resulting in an improvement in mechanical properties. This paper presents an original experimental investigation on grout with added carbon nanotubes (CNTs). The samples were prepared with different percentages of CNTs, up to 1.2 wt% with respect to the binder, and underwent three‐point bending tests in crack mouth opening displacement mode and compressive tests. The results showed that very small additions (up to 0.12 wt% of CNTs) increased not only flexural and compressive strengths (+73% and 35%, respectively, in comparison with plain mortar) but also fracture energy (+80%). These results can be explained on the basis of a reduction in porosity, as evidenced by mercury intrusion porosimetry, as well as by a crack bridging mechanism and by the probable formation of nucleation sites for hydration products, as observed through scanning electron microscopy.

AimChronic hepatitis B (CHB) patients with normal alanine aminotransferase (ALT) levels are not free from significant hepatic lesions. Recently, there has been an improved understanding of the clinical significance of quantitative hepatitis B core antibody levels (qAnti‐HBc) during CHB management. In this cross‐sectional study, we evaluated the utility of qAnti‐HBc in identifying significant liver inflammation in CHB patients.MethodsA total of 469 patients (training set, n = 363; validation set, n = 106) who underwent liver biopsy (LB) were included. The qAnti‐HBc levels were quantified and the relationship between histology and serum markers was systematically analyzed.ResultsIn the training set, qAnti‐HBc levels were found to have significant diagnostic value for moderate to severe liver inflammation (≥G2) in all patients (area under the receiver operating characteristic curve [AUROC] = 0.768; 95% confidence interval [CI], 0.721–0.810; P < 0.001) and in patients with normal or near‐normal ALT levels (AUROC = 0.767; 95% CI, 0.697–0.828; P < 0.001). Our novel index (AC index) for the identification of ≥G2 inflammation, which combined the qAnti‐HBc and ALT levels, significantly improved diagnostic performance (AUROC = 0.813; 95% CI, 0.768–0.852) compared to the use of ALT alone (AUROC = 0.779; 95% CI, 0.732–0.821) in all patients. In the validation set, the AC index showed an improved AUROC of 0.890 (95% CI, 0.814–0.942) and 0.867 (95% CI, 0.749–0.943) in all patients and patients with normal ALT levels, respectively.ConclusionsThe qAnti‐HBc level predicts significant liver inflammation well, even in patients with normal or near‐normal ALT levels. Compared with the conventional ALT level, the AC index is a more reliable non‐invasive biomarker for significant liver inflammation in CHB patients.
Will cloud computing make the Information Technology (IT) department obsolete?
Authors: Vithayathil Joseph 
Published: July 2017

AbstractThe rapid adoption and growth of cloud computing is creating unprecedented change in the manner in which IT services are procured, managed, and deployed. Cloud computing is forcing firms to rethink traditional IT governance practices while raising new and fundamental questions for scholars and practitioners. This paper identifies the major areas of change and highlights governance issues that arise with the adoption of cloud computing. The focus of this paper is on the organizational impact on IT governance under cloud computing. The paper posits (1) that successful IT departments under cloud computing will transform into new roles that address internal customer‐facing issues and external cloud‐facing issues, (2) firms that mitigate information asymmetry under cloud computing will show higher firm performance, and (3) firms that offer superior cloud‐sourced IT service attributes of internal prices, quality, variety, and competition in the cloud will show higher firm performance.
Composition‐induced phase transitions and enhanced electrical properties in bismuth sodium titanate ceramics
Authors: Yin Jie , Zhao Chunlin , Zhang Yuxing , Wu Jiagang 
Published: July 2017

AbstractHere, the composition‐induced phase transition and enhanced electrical properties were investigated in terms of lead‐free {[Bi0.5(Na0.82−xK0.18Lix)0.5]1−ySry}TiO3 (BNKLST‐x/y, x=0‐0.175 and y=0‐0.125) ceramics. The rhombohedral and tetragonal phase boundary can be constructed, and then the enhancement of piezoelectric properties (d33~271 pC/N and kp~0.38) can be observed for x=0.10 and y=0.05, which is superior to most reported results in polycrystalline BNT‐based ceramics. In particular, a fatigue‐free behavior after 106 polarization switching cycles was shown in the BNKLST‐0.10/0.05 ceramics due to the reversible field‐induced phase transition, and a slight decrease in d33 (~4.5%) was also shown. More importantly, the general model of electric field, temperature, and composition‐induced phase transition was employed to explain the enhancement of piezoelectric and fatigue properties. We believe that the composition design of this system can promote the development of bismuth sodium titanate lead‐free ceramics.
Development of a novel proton conducting fuel cell based on a Ni‐YSZ support

Published: July 2017

AbstractA new proton conducting fuel cell design based on the BZCYYb electrolyte is studied in this research. In high‐performance YSZ‐based SOFCs, the Ni‐YSZ support plays a key role in providing required electrical properties and robust mechanical behavior. In this study, this well‐established Ni‐YSZ support is used to maintain the proton conducting fuel cell integrity. The cell is in a Ni‐YSZ (375 μm support)/Ni‐BZCYYb (20 μm anode functional layer)/BZCYYb (10 μm electrolyte)/LSCF‐BZCYYb (25 μm cathode) configuration. Maximum power density values of 166, 218, and 285 mW/cm2 have been obtained at 600°C, 650°C, and 700°C, respectively. AC impedance spectroscopy results show values of 2.17, 1.23, and 0.76 Ω·cm2 at these temperatures where the main resistance contributor above 600°C is ohmic resistance. Very fine NiO and YSZ powders were used to achieve a suitable sintering shrinkage which can enhance the electrolyte sintering. During cosintering of the support and BZCYYb electrolyte layers, the higher shrinkage of the support layer led to compressive stress in the electrolyte, thereby enhancing its densification. The promising results of the current study show that a new generation of proton conducting fuel cells based on the chemically and mechanically robust Ni‐YSZ support can be developed which can improve long‐term performance and reduce fabrication costs of proton conducting fuel cells.
CD19 regulates ADAM28‐mediated Notch2 cleavage to control the differentiation of marginal zone precursors to MZ B cells

Published: July 2017

AbstractAs the first line of defence, marginal zone (MZ) B cells play principal roles in clearing blood‐borne pathogens during infection and are over‐primed in autoimmune diseases. However, the basic mechanisms underlying MZ B‐cell development are still unclear. We found here that CD19 deficiency blocked the differentiation of marginal zone precursors (MZP) to MZ B cells, whereas CD19 expression in CD19‐deficient MZP rescues MZ B‐cell generation. Furthermore, CD19 regulates Notch2 cleavage by up‐regulating ADAM28 expression in MZP. Finally, we found that CD19 suppressed Foxo1 expression to promote ADAM28 expression in MZP. These results suggest that CD19 controls the differentiation of MZP to MZ B cells by regulating ADAM28‐mediated Notch2 cleavage. Thus, we demonstrated the basic mechanisms underlying the differentiation of MZP to MZ B cells.

AbstractBackgroundPsoriasis and migraine share several pathogenetic mechanisms due to systemic inflammation, which increase the risk of developing cardiovascular disease.ObjectiveOur aim was to investigate the prevalence of migraine with (MA) and without aura (MO) in the psoriatic population, investigating a possible new comorbidity of the psoriatic disease.MethodsWe referred 68 psoriatic patients to a nine questions survey formulated on the basis of the International Headache Society (IHS) diagnostic criteria for migraine. Then, in the case of MA, the mean monthly number of migraine crises was assessed. Data of psoriatic patients were then compared with those of a psoriasis‐free control group composed of 235 migraine patients (with and without aura).ResultsA clinical diagnosis of migraine was performed in 32 psoriasis patients with a great prevalence in women (F: 87.50% ‐ M: 12.5%). Moreover, we found a much higher prevalence (62.5%) of MA, with the remaining 37.5% diagnosed with MO. Comparing the prevalence of MA between psoriasis + migraine patients and the control group we observed a statistical significative difference (P < 0.0001); furthermore, the number of MA crises was significantly higher (P < 0.0001) in patients with psoriasis with respect to the MA control group.ConclusionsWe showed a significant association between psoriasis and migraine, especially MA, probably due to common pathogenetic mechanisms, but further studies are needed to assess their interplay in developing cardiovascular diseases.

AbstractBackgroundRosettes, a dermoscopic structure characterized by four white points arranged as a 4‐leaf clover, supports the dermoscopic diagnosis of actinic keratosis (AK) or squamous cell carcinoma (SCC).ObjectiveThe association of rosettes with other dermoscopic structures in AK or SCC and their distribution has not been analysed yet.MethodsWe conducted a prospective study of patients with histologically proven AK or SCC who presented dermoscopic rosettes at initial evaluation.ResultsA total of 56 tumours were collected (94.6% AK and 5.4% SCC). Thirty‐seven (66.1%) lesions were non‐pigmented and 19 (33.9%) pigmented. The most common dermoscopic findings were erythema (53; 94.6%) and scale (42; 75%). White circles were present in 21 lesions (37.5%); pigmented pseudonetwork in 18 (32.1%) and multiple grey to brown dots and globules in 14 (25%). Rosettes were distributed focally in 9 (16.1%) and generalized in 47 (83.9%). The rosette pattern (rosettes as the main structure) was observed only in AK (19; 35.8%).LimitationsThe analysis was not blinded. The distinction between focal distribution (up to 3 rosettes) or generalized could be considered arbitrary.ConclusionThe rosette pattern identified in AK may be a specific pattern for AK.
