Published: November 2017

Purpose
The purpose of this paper is to develop some picture uncertain linguistic aggregation operators based on Bonferroni mean operators, which is combined with multiple attribute decision-making (MADM) and has applied the proposed MADM model for selecting the service outsourcing provider of communications industry under picture uncertain linguistic environment.

Design/methodology/approach
The service outsourcing provider selection problem of communications industry can be regarded as a typical MADM problem, in which the decision information should be aggregated. In this paper, the authors investigate the MADM problems with picture uncertain linguistic information based on traditional Bonferroni mean operator.

Findings
The results show that the proposed model can solve the MADM problems within the context of picture uncertain linguistic information, in which the attributes are existing interaction phenomenon. Some picture uncertain aggregation operators based on Bonferroni mean have been developed. A case study of service outsourcing provider selection problem of communications industry is provided to illustrate the effectiveness and feasibility of the proposed methods. The results show that the proposed methods are useful to aggregate the picture uncertain linguistic decision information in which the attributes are not independent so as to select the most suitable supplier.

Research limitations/implications
The proposed methods can solve the picture uncertain linguistic MADM problem, in which the interactions exist among the attributes. Therefore, it can be used to solve service outsourcing provider selection problems and other similar management decision problems.

Practical implications
This paper develops some picture uncertain aggregation operators based on Bonferroni mean and further presents two methods based on the proposed operators for solving MADM problems. It is useful to deal with multiple attribute interaction decision-making problems and suitable to solve a variety of management decision-making applications.

Social implications
It is useful to deal with multiple attribute interaction decision-making problems and suitable to solve a variety of management decision-making applications.

Originality/value
The paper investigates the MADM problems with picture uncertain linguistic information based on traditional Bonferroni mean operator and develops the picture uncertain linguistic Bonferroni mean operator and picture uncertain linguistic geometric Bonferroni mean operator, picture uncertain linguistic weighted Bonferroni mean operator and picture uncertain linguistic weighted geometric Bonferroni mean operator for aggregating the picture uncertain linguistic information, respectively.

This is the first paper introducing the adaptive leadership model to academic libraries.
Improving the Progress of Research & Development (R&D) Projects by Selecting an Optimal Alliance Structure and Partner Type
Authors: Choi Jeongho , Contractor Farok J. 
Published: November 2017

AbstractThis paper extends the study of alliance governance structure by examining what alliance structure, coordination mechanisms and partner type best enhance the likelihood of Research and Development (R&D) progress or performance. We specially focus on the coordination and interaction mechanism of alliances, through which we classify the alliance governance structures in order to reflect the more complex alliance types and contracts used in today's R&D. Using data from 255 biopharmaceuticals between the years 2000 and 2004, we found that, ceteris paribus, a moderate degree of inter‐partner interaction and a moderately complex (non‐equity‐based) alliance contract contributes more to a better R&D alliance performance than those structures that are too simple or too organizationally embedded (e.g. equity joint ventures), which possibly increase the risk of misalignment and miscommunication between allies. In addition, due to the reduced opportunism and the diverse resource (e.g. technology) pooled in the alliance, allying with diverse organizational partners such as non‐profit research institutes and universities is more likely to enhance the R&D performance. Our findings provide insightful strategic implications to practitioners in designing an appropriate alliance governance structure and choosing the right partner type for a successful R&D collaboration.

Published: November 2017

AbstractThe level of saturated fatty acids, such as palmitic acid (PA), correlates with chronic inflammation in obese and metabolic syndrome patients. However, low level of vitamin D3 is observed in those conditions. The aim of this study is to investigate effects of 1α,25(OH)2D3 on PA‐treated THP‐1 cells. Using quantitative real‐time polymerase chain reaction, we measure mRNA expression of pro‐inflammatory cytokines: TNF‐α, Interleukin (IL)‐1β, IL‐6, and chemokine IL‐8 under PA and 1α,25(OH)2D3 influence. PA, at all concentrations (25–100 μM), enhanced LPS stimulatory effect on those mRNA expression compared to LPS‐treated and ‐untreated cells. Combination with 1α,25(OH)2D3 increased cytokine expression at high (10−6 M) and high‐normal (10−8 M) concentrations compared to PA + LPS and LPS alone, both for 2 and 24 h. However, low‐normal (10−10 M) and low (10−12 M) levels of 1α,25(OH)2D3 could not enhance PA effect, but mRNA expression of pro‐inflammatory cytokine was higher than LPS‐treated cells. Upstream pathway of 1α,25(OH)2D3, which is cholecalciferol, also gave the similar result. Further, inhibition of calcium pathway does not play a role in this mechanism. Thus, these findings support pro‐inflammatory effect of PA and vitamin D3 on innate immune response, especially on fat‐induced inflammation.Practical ApplicationThe effect of vitamin D3 on chronic inflammation in obesity is uncertain. This study shows an in vitro possibility that vitamin D3 could exaggerate inflammation when combined with high SFAs. The idea of using vitamin D3 supplement to modulate inflammation in fat‐related inflammation needs further refined experiments before its clinical application.

Published: November 2017

AbstractBackgroundThis study assessed the frequency of short‐term oral corticosteroid use in adults with diabetes, examined the incidence of fractures, venous thromboembolism (VTE), and hospitalization for sepsis after corticosteroid use, and evaluated whether preventative medications mitigated adverse events.MethodsA longitudinal study (2012–14) was conducted of 1 548 945 adults (aged 18–64 years) who received healthcare coverage through a large national health insurer. Incidence rate ratios (IRR) were calculated using conditional Poisson regression.ResultsShort‐term oral corticosteroids were used by 23.9%, 20.8%, and 20.9% of adults with type 2 diabetes, type 1 diabetes, and no diabetes, respectively, during the 3‐year period (P < 0.001). Baseline risks of fracture, VTE, and sepsis were greater for individuals with than without diabetes (P < 0.001). The combined effect of having diabetes and using corticosteroids was greater than the sum of the individual effects (synergy indices of 1.17, 1.23, 1.30 for fracture, VTE, and sepsis, respectively). The IRR for VTE in the 5–30 days after corticosteroid use was 3.62 (95% confidence interval [CI] 2.41–5.45). Fractures increased in the 5–30 days after corticosteroid use (IRR 2.06; 95% CI 1.52, 2.80), but concomitant use of ergocalciferol mitigated this risk (IRR 1.13; 95% CI 0.12, 11.07). The risk of hospitalization for sepsis was elevated with corticosteroid use (IRR 3.79; 95% CI 2.05, 7.01), but was mitigated by the concomitant use of statins.ConclusionsShort‐term oral corticosteroid use is common in adults with diabetes and is associated with an elevated, but low, risk of adverse events. The findings suggest that preventative medications may mitigate risk.
Autoconstruction 2.0: Social Media Contestations of Racialized Violence in Complexo do Alemão
Authors: Prouse Carolyn 
Published: November 2017

AbstractActivists and journalists in Complexo do Alemão, Rio de Janeiro are using social media to intervene in the violence that shapes their communities. In this article I draw on critical urban and digital media theory to understand how militarized policing, the spatialization of race, and discourses of criminalization influence favela populations. I examine how these discursive and material violences are motivating residents to autoconstruct new digital communities. Through digital autoconstruction, journalists and activists are using social media technologies to safely direct mobility, to witness police violence, and to unsettle socio‐spatial imaginaries of endemic crime. As such, they are deploying digital practices to disrupt material, epistemological, and discursive mechanisms of social control. These actions show that digital technologies are always‐already embodied and take shape through material histories, such as those of racialized state violence. Journalists and activists in Complexo do Alemão ultimately demonstrate that targets of violence are not simply victims of digital and violent surveillance, but are active in creating new digital relationships of care across diverse scales, transforming these technologies in the process.
External validity in perinatal research
Authors: Odibo Anthony O. , Acharya Ganesh 
Published: November 2017

AbstractRecent studies are beginning to focus on the external validity of well conducted internally valid research. This review gives an overview of external validity, the dimensions involved and suggestions for when future intervention trials are designed, using examples from perinatal research. Finally, we remind the perinatal researcher that it is their duty to provide extensive details beyond those needed to establish internal validity. The latter would help clinicians to determine whether the intervention is applicable to their population.
The interstitium conducts extrarenal storage of sodium and represents a third compartment essential for extracellular volume and blood pressure homeostasis

Published: November 2017

AbstractThe role of salt in the pathogenesis of arterial hypertension is not well understood. According to the current understanding, the central mechanism for blood pressure (BP) regulation relies on classical studies linking BP and Na+ balance, placing the kidney at the very centre of long‐term BP regulation. To maintain BP homeostasis, the effective circulating fluid volume and thereby body Na+ content has to be maintained within very narrow limits. From recent work in humans and rats, the notion has emerged that Na+ could be stored somewhere in the body without commensurate water retention to buffer free extracellular Na+ and that previously unidentified extrarenal, tissue‐specific regulatory mechanisms are operative regulating the release and storage of Na+ from a kidney‐independent reservoir. Moreover, immune cells from the mononuclear phagocyte system not only function as local on‐site sensors of interstitial electrolyte concentration, but also, together with lymphatics, act as systemic regulators of body fluid volume and BP. These studies have established new and unexpected targets in studies of BP control and thus the pathophysiology of hypertension: the interstitium/extracellular matrix of the skin, its inherent interstitial fluid and the lymphatic vasculature forming a vessel network in the interstitium. Aspects of the interstitium in relation to Na+ balance and hypertension are the focus of this review. Taken together, observations of salt storage in the skin to buffer free extracellular Na+ and macrophage modulation of the extracellular matrix and lymphatics suggest that electrolyte homeostasis in the body cannot be achieved by renal excretion alone, but also relies on extrarenal regulatory mechanisms.
Vector Field Map Representation for Near Conformal Surface Correspondence
Authors: Wang Y. , Liu B. , Zhou K. , Tong Y. 
Published: November 2017

AbstractBased on a new spectral vector field analysis on triangle meshes, we construct a compact representation for near conformal mesh surface correspondences. Generalizing the functional map representation, our representation uses the map between the low‐frequency tangent vector fields induced by the correspondence. While our representation is as efficient, it is also capable of handling a more generic class of correspondence inference. We also formulate the vector field preservation constraints and regularization terms for correspondence inference, with function preservation treated as a special case. A number of important vector field–related constraints can be implicitly enforced in our representation, including the commutativity of the mapping with the usual gradient, curl, divergence operators or angle preservation under near conformal correspondence. For function transfer between shapes, the preservation of function values on landmarks can be strictly enforced through our gradient domain representation, enabling transfer across different topologies. With the vector field map representation, a novel class of constraints can be specified for the alignment of designed or computed vector field pairs. We demonstrate the advantages of the vector field map representation in tests on conformal datasets and near‐isometric datasets.
Infantile hemangioma: pathogenesis and mechanisms of action of propranolol
Authors: Rotter Anita , de Oliveira Zilda Najjar Prado 
Published: November 2017

SummaryInfantile hemangioma (IH) is the most common benign tumor of childhood, with a prevalence of 4 % to 10 %. It is characterized by a proliferative rapid growth phase, which starts after a few weeks of life, followed by a slow regression phase. In IH cases that are potentially disfiguring or life‐threatening (10 % to 15 % of all cases), systemic therapy should be promptly initiated.Data sourceThe present study reviews published scientific articles available in reliable electronic databases. Selected were all studies that evaluated the pathogenesis of IH and the mechanisms of action of propranolol.ConclusionsThe pathogenesis of IH has not been fully elucidated. Studies show that, in the proliferative phase of IH, there is an imbalance of angiogenic factors and an increase in the levels of vascular endothelial growth factor and matrix metalloproteinases 2 and 9. In the regression phase, the levels of these factors decrease, whereas those of antiangiogenic factors, including tissue inhibitors of matrix metalloproteinases, increase. Since 2008, propranolol has become the drug of choice in the treatment of IH, targeting vascular tone, angiogenesis, and apoptosis. Current insights into the pathogenesis of IH allow for the development of new therapeutic strategies.
Rye bread and synthetic bread odorants – effective trap bait and lure for German cockroaches
Authors: Pol Joshua , Gries Regine , Gries Gerhard 
Published: November 2017

AbstractBread‐in‐beer and bread‐in‐water are prevalent home recipe trap baits for attracting German cockroaches (GCRs), Blattella germanica (L.) (Dictyoptera: Blattellidae), which are significant urban pests. Our objectives were to (1) test the attractiveness of these baits, (2) study the underlying factors of GCR attraction, and (3) determine whether a blend of synthetic bread odorants could replace bread in a trap lure. In large‐arena laboratory experiments with laboratory‐reared GCR males, traps baited with rye bread not only captured eightfold more males than unbaited control traps but also most males released into bioassay arenas. Neither beer nor water enhanced the attractiveness of bread. Bread crust as a bait was more effective than bread crumbs. As Porapak Q headspace volatile extracts of rye bread attracted GCRs, all rye bread odorants in extracts were identified by gas chromatography‐mass spectrometry. Synthetic rye bread odorants and other known bread odorants were then assembled into a master blend. This master blend, and even partial blends lacking certain groups of organic volatiles such as aldehydes and ketones, proved very attractive to GCRs. We conclude that rye bread could be used as an effective bait in retainer traps or, laced with insecticide, as a food source in bait stations. A lure of synthetic bread odorants may eventually replace bread as bait, but the minimum number of essential odorants for that lure has yet to be determined.

AimWith an aging Singapore population, there is an increasing demand for dementia care. The present study aimed to evaluate the effectiveness and cost‐effectiveness of the Primary Care Dementia Clinic (PCDC) in comparison with the Memory Clinic (MC; hospital‐based) and other polyclinics.MethodsA quasi‐experimental design was implemented. Effectiveness of PCDC was assessed through caregiver satisfaction, quality of life (caregiver‐rated) and adverse events rates. Quality‐of‐Life measures using the EuroQol 5 Dimension Questionnaire (EQ‐5D) at baseline, 6 months and 12 months was assessed. Costs were calculated from a societal perspective. The incremental cost‐effectiveness of the PCDC was compared with MC and other polyclinics.ResultsThe present study showed that quality of life and the rate of adverse events at 12 months were similar between the three groups. Caregiver satisfaction at 12 months was higher in the PCDC group when compared with other polyclinics. There were no observed differences in societal cost between the three groups. At 6‐month follow up, direct medical costs for PCDC were significantly lower that of other polyclinics. At 12‐month follow up, PCDC patients had higher Quality Adjusted Life Years (QALYs) compared with the MC group.ConclusionPCDC provided effective care, similar to care at MC and better than care at other polyclinics. Caregiver satisfaction was higher for the PCDC group, and PCDC patients had lower direct medical costs at 6‐month follow up. Given these findings, adopting a PCDC model in other polyclinics in Singapore can be beneficial for optimal right siting of patients. Geriatr Gerontol Int 2018; 18: 479–486.
The Role of Negative Affect on Headache‐Related Disability Following Traumatic Physical Injury

Published: November 2017

ObjectiveAcute postinjury negative affect (NA) may contribute to headache pain following physical injury. Early psychiatric–headache comorbidity conveys increased vulnerability to chronic headache‐related disability and impairment. Yet, it is unknown whether NA is involved in the transition to chronic headache related‐disability after injury. This prospective observational study examined the role of acute postinjury NA on subacute and chronic headache‐related disability above and beyond nonpsychiatric factors.MethodsEighty adult survivors of single‐incident traumatic physical injury were assessed for negative affect (NA): a composite of depression and anxiety symptoms, and symptoms of posttraumatic stress disorder (PTSS) during the acute 2‐week postinjury phase. NA was examined as the primary predictor of subacute (6‐week) and chronic (3‐month) headache‐related disability; secondary analyses examined whether the individual NA components differentially impacted the outcomes.ResultsHierarchical linear regression confirmed NA as a unique predictor of subacute (Cohen'sf 2 = 0.130;P = .005) and chronic headache related‐disability (Cohen'sf 2 = 0.160;P = .004) beyond demographic and injury‐related factors (sex, prior headaches, and closed head injury). Upon further analysis, PTSS uniquely predicted greater subacute (Cohen'sf 2 = 0.105;P = .012) and chronic headache‐related disability (Cohen'sf 2 = 0.103;P = .022) above and beyond demographic and injury‐related factors, depression, and anxiety. Avoidance was a robust predictor of subacute headache impairment (explaining 15% of the variance) and hyperarousal was a robust predictor of chronic headache impairment (10% of the variance).ConclusionAlthough NA consistently predicted headache‐related disability, PTSS alone was a unique predictor above and beyond nonpsychiatric factors, depression, and anxiety. These results are suggestive that early treatment of acute postinjury PTSS may correlate with reductions in disability and negative physical health sequelae associated with PTSS and chronic headache.
