Revenue sharing contract coordination of wind turbine order policy and aftermarket service based on joint effort
Authors: Liang Ling , Xie Jiaping , Liu Luhao , Xia Yu 
Published: March 2017

Purpose
The purpose of this paper is to discuss how wind farms attract wind turbine manufacturers to get involved in wind turbines’ maintenance service with revenue sharing contract of bundled service under which the background of operation and maintenance (O&M) aftermarket of wind turbine exists. The authors also try to extend the results to the application of product plus service business mode on large-scale equipment O&M service. At present, Chinese wind power industry is suffering from production capacity redundancy. The profit levels for both wind farm and wind turbine manufacturers are relatively low. It is significant for Chinese wind power industry development to coordinate the supply chain of wind power in order to reduce O&M costs and increase revenues.

Design/methodology/approach
The present paper discusses product plus aftermarket service contract design on the background of closed-loop product service chain and uncertain equipment demand using revenue sharing contract model.

Findings
If centralized decision making is assumed, the authors find that the wind turbine order increases as the aftermarket service effort level and aftermarket service profit increase; aftermarket service effort level is positively correlative to the service efficiency. On the other hand, if decentralized decision making is assumed, the wind turbine order increases as share of the aftermarket service chain by manufacturer to wind farm increases and share of product supply chain by wind farm to manufacturer decreases. The optimal effort level of wind farm increases as the share of aftermarket service chain increases while the optimal effort level of the manufacturer is a concave function of share of aftermarket service chain if service quality linear correlates with effort level. Meanwhile, the authors find that the revenues of the product supply chain and aftermarket service chain have a concave relationship. This relationship is not affected by the format of relationship between service quality and effort level (linear or exponential).

Practical implications
The results could potentially be used to provide the wind turbine manufacturer with a greater profit space and satisfy wind farm’s equipment maintenance demand at the same time. It can also guide the practice of revenue sharing in the aftermarket service and manufacturing servitization.

Originality/value
In this model, the authors assumed that both the forward revenue sharing of power generation by wind farm to manufacturer and the backward revenue sharing of maintenance service by the manufacturer to wind farm exist in closed-loop product service chain. Then the authors discussed channel coordination of such cross-revenue sharing contract.
Dynamic customer preference analysis for product portfolio identification using sequential pattern mining
Authors: Yu Li , Zhang Zaifang , Shen Jin 
Published: March 2017

Purpose
In the initial stage of product design, product portfolio identification (PPI) aims to translate customer needs (CNs) into product specifications (PSs). This is an essential task, since understanding what customers really want is at the center of product design. However, design information is incomplete and design knowledge is minimal during this stage. Furthermore, PPI is often a confusing and frustrating task, especially when customer preferences are changing rapidly. To facilitate the task, the purpose of this paper is to capture the time-sensitive mapping relationship between CNs and PSs.

Design/methodology/approach
This paper proposes a design sequential pattern mining model to uncover implicit but valuable knowledge from chronological transaction records. First, CNs and PSs from these records are transformed and connected according to the transaction time. Second, procedures such as litemset generation, data transformation and pattern mining are conducted based on the AprioriAll algorithm. Third, the uncovered patterns are modified and applied by engineers.

Findings
Using the retrieved patterns, engineers can keep up with the dynamics of customer preferences with regard to different PSs.

Research limitations/implications
Computational experiments on a case study of customization of desktop computers show that the proposed method is capable of extracting useful sequential patterns from a design database.

Originality/value
Considering the times tamps of the transactions, a sequential pattern mining-based method is proposed to extract valuable patterns. These patterns can help engineers identify market trends and the correlation among PSs.
A UAE case study: experiential learning through effective educational partnerships
Authors: Minhas Wasif , Perret Jo 
Published: March 2017

Purpose
One of the largest higher education institutes (HEI) in the United Arab Emirates (UAE) and another public sector organization (PSO) responsible for promoting heritage, history and culture in the tourism sector formed an informal partnership in 2012. The purpose of this paper is to give Emirati students an opportunity to undertake projects based on their heritage, communities and develop their skills by experiencing “learning by doing.”

Design/methodology/approach
Projects briefs were provided by the PSO and followed the curriculum requirements of first year bachelor programs. In February 2013, faculty from different departments within the HEI met with PSO representative to explore how both organizations could collaborate. The conversation also focused on how the PSO could take advantage of readily available resources of creativity and innovation at the HEI. An innovative, cross-discipline, joint-marketing project was developed in line with the curriculum and PSO needs. By June, 2013, all students had undertaken projects which led toward developing recommendations and materials to promote the brief from PSO of “Raising Awareness” and “Increasing Visitor Numbers.”

Findings
Students from different disciplines produced different elements to meet the brief; however, they all followed a similar approach of research, analysis and evaluation. Although such projects are difficult to manage, staff found they had a profound effect on students’ motivation, personal development and overall learning experience.

Originality/value
This case study provides an insight into how experiential learning can be fostered through educational partnerships in the UAE context and beyond. It also highlights the importance of technology and informal relationships between partnering institutions.

Authors: Molin Jonas , Åge Lars-Johan 
Published: March 2017

PurposeThe purchasing of services is a significantly under-researched area. The purpose of this study is to suggest a conceptual model of service sourcing relationships, including the post-contract phase.Design/methodology/approachA qualitative methodology involving two longitudinal case studies that were analyzed with a grounded theory approach to build a conceptual model was applied.FindingsThe proposed model consists of a core process that is termed “business streamlining” and denotes the process by which four interrelated dimensions are managed to making the business processes of the buying organization simpler and more effective and/or productive.Research limitations/implicationsAlthough the research methodology is qualitative and does not allow statistical generalization, the study does provide valuable insights into the management of the service sourcing process.Practical implicationsThe model proposed in this study can be utilized by managers to impose a useful conceptual structure on otherwise fluid and intangible processes, which makes them easier to analyze and facilitates strategic corporate decision-making.Originality/valueThe paper proposes a model that grasps the dynamics and reality of service (out-) sourcing relationships, including the ongoing relationship management process.

Trust in marketing’s use of information from sales: the moderating role of power
Authors: Keszey Tamara , Biemans Wim 
Published: March 2017

PurposeThis paper aims to improve marketing managers’ use of information from sales. The authors propose and empirically test the link between cross-functional trust and marketing’s use of information from sales, and whether this effect is contingent on marketing’s power within the firm.Design/methodology/approachCross-sectional survey data were collected from 338 large-scale Hungarian firms. Structural equation modeling and bootstrap procedures were used to test the hypotheses.FindingsThe effect of cross-functional trust on marketing managers’ use of sales information is fully mediated by sales–marketing integration and marketing’s perception of information quality. However, the power of marketing within the firm moderates this mediating relationship.Research limitations/implicationsThis paper provides empirical evidence concerning the mediating mechanisms of transferring cross-functional trust to marketing’s successful use of information from sales. The findings imply that cross-functional trust can improve marketing managers’ use of sales information of firms with powerful marketing units by facilitating integration, whereas it can improve the use of sales information of firms with low marketing power by improving marketing managers’ perception of information quality from sales.Originality/valueThis is the first study that models and empirically investigates marketing managers’ use of information collected by sales. The current study conceptually links and advances extant knowledge on the literatures on the sales–marketing interface and utilization of market information at the individual level and increases the understanding of how cross-functional trust contributes to information use under different contingencies of marketing power.
The effects of organizational commitment and structural empowerment on patient safety culture
Authors: Horwitz Sujin K. , Horwitz Irwin B. 
Published: March 2017

PurposeThe purpose of this paper is to investigate the relationship between patient safety culture and two attitudinal constructs: affective organizational commitment and structural empowerment. In doing so, the main and interaction effects of the two constructs on the perception of patient safety culture were assessed using a cohort of physicians.Design/methodology/approachAffective commitment was measured with the Organizational Commitment Questionnaire, whereas structural empowerment was assessed with the Conditions of Work Effectiveness Questionnaire-II. The abbreviated versions of these surveys were administered to a cohort of 71 post-doctoral medical residents. For the data analysis, hierarchical regression analyses were performed for the main and interaction effects of affective commitment and structural empowerment on the perception of patient safety culture.FindingsA total of 63 surveys were analyzed. The results revealed that both affective commitment and structural empowerment were positively related to patient safety culture. A potential interaction effect of the two attitudinal constructs on patient safety culture was tested but no such effect was detected.Research limitations/implicationsThis study suggests that there are potential benefits of promoting affective commitment and structural empowerment for patient safety culture in health care organizations. By identifying the positive associations between the two constructs and patient safety culture, this study provides additional empirical support for Kanter’s theoretical tenet that structural and organizational support together helps to shape the perceptions of patient safety culture.Originality/valueDespite the wide recognition of employee empowerment and commitment in organizational research, there has still been a paucity of empirical studies specifically assessing their effects on patient safety culture in health care organizations. To the authors’ knowledge, this study is the first empirical study to examine the relationship between structural empowerment as proposed by Kanter and the culture of patient safety using physicians.
Divide and conquer: the Pseudomonas aeruginosa two‐component hybrid SagS enables biofilm formation and recalcitrance of biofilm cells to antimicrobial agents via distinct regulatory circuits
Authors: Petrova Olga E. , Gupta Kajal , Liao Julie , Goodwine James S. , Sauer Karin 
Published: March 2017

SummaryThe opportunistic pathogen Pseudomonas aeruginosa forms antimicrobial resistant biofilms through sequential steps requiring several two‐component regulatory systems. The sensor‐regulator hybrid SagS plays a central role in biofilm development by enabling the switch from the planktonic to the biofilm mode of growth, and by facilitating the transition of biofilm cells to a highly tolerant state. However, the mechanism by which SagS accomplishes both functions is unknown. SagS harbours a periplasmic sensory HmsP, and phosphorelay HisKA and Rec domains. SagS domain was used as constructs and site‐directed mutagenesis to elucidate how SagS performs its dual functions. It was demonstrated that HisKA‐Rec and the phospho‐signalling between SagS and BfiS contribute to the switch to the biofilm mode of growth, but not to the tolerant state. Instead, expression of SagS domain constructs harbouring HmsP rendered ΔsagS biofilm cells as recalcitrant to antimicrobial agents as wild‐type biofilms, likely by restoring BrlR production and cellular c‐di‐GMP levels to wild‐type levels. Restoration of biofilm tolerance by HmsP was independent of biofilm biomass accumulation, RsmA, RsmYZ, HptB and BfiSR‐downstream targets. Our findings thus suggest that SagS likely makes use of a “divide‐and‐conquer” mechanism to regulate its dual switch function, by activating two distinct regulatory networks via its individual domains.
Ancestral Variation in Orbital Rim Shape: A Three‐Dimensional Pilot Study
Authors: Rubin Katie M. , DeLeon Valerie B. 
Published: March 2017

AbstractTraditional nonmetric methods of ancestry assessment posit orbital rim shape varies among ancestral groups. This pilot study uses morphometric analysis of 3D orbital variation to test discrimination among individuals of primarily European, African, and Asian ancestry. Although the size and nature of the sample analyzed limit inferences for other samples, principal components analysis suggests ancestry has a significant effect on rim shape (p = 2.93e‐04). European orbits display more marked folding of the orbit in the sagittal plane than either African or Asian orbits, while the lateral margin of African orbits lies further posterior relative to the medial margin when compared to Asian orbits. The findings suggest curviplanar relationships are the most ancestrally informative aspect of orbital rim shape; these relationships may be distorted by perspective based on orientation of the skull relative to the viewer in traditional nonmetric analyses. Additional studies on geometric morphometric approaches to ancestry assessment are therefore warranted.
Turning in mid‐air allows aphids that flee the plant to avoid reaching the risky ground
Authors: MERESMAN Yonatan , BEN‐ARI Matan , INBAR Moshe 
Published: March 2017

AbstractWhen forced to drop from the plant, flightless arboreal insects can avoid reaching the risky ground by maneuvering their body through the air. When wingless pea aphids (Acyrthosiphon pisum) are threatened by natural enemies, they often drop off their host plant while assuming a stereotypic posture that rotates them in mid‐air, aligning them with their feet pointing downwards. This position may increase their chances of re‐clinging onto lower plant parts and avoid facing the dangers on the ground, although its effectiveness in realistic field conditions has not been tested. We performed both laboratory and outdoor experiments, in which we dropped aphids upon host plants to quantify clinging success in plants with different characteristics such as height and leaf size. Live aphids had twofold higher clinging rates than dead ones, indicating that clinging success is indeed affected by the active aerial‐righting of dropping aphids. The ability to cling was positively dependent on the plants' foliage cover as viewed in vertical direction from above. Therefore, we released aphids in commercial alfalfa (Medicago sativa) fields with varying plant heights and foliage cover and induced them to drop. Most (up to 75%) of the aphids avoided reaching the ground in taller plants (65 cm), and 17% in shorter plants (21 cm), demonstrating the efficiency of the aphids' response in averting risks: both those of an approaching enemy on the plant and the plethora of new risks on the ground. Evidently, even in complex field environment, the aerial‐righting mechanism can substantially reduce the possible risks following escape from a predator.

AbstractAimWe designed this study to evaluate the prevalence of comorbidities, their monitoring states and association with treatment medication in Korean rheumatoid arthritis (RA) patients compared with patients from other countries.MethodsWe analyzed 1050 RA patients from 11 Korean centers and compared them with 3520 patients from 16 other countries using an international, cross‐sectional study evaluating comorbidities of RA (COMORA) database.ResultsAnnual evaluations of cardiovascular (CV) risk were less frequently performed in Korea (P = 0.0011). The prevalence of CV‐associated morbidity was similar between Korean and international RA patients, although the proportions of current smokers, patients with a family history of CV disease, patients with hyperlipidemia, and patients with Framingham score > 20% were significantly lower in Korea (P < 0.0001 for all), and the antiplatelet agents were more optimally used in Korea (P = 0.0004). Prostate cancer screening was less frequently performed compared to other countries (P < 0.0001). Less than 10% of Korean RA patients were given influenza and pneumococcal vaccinations according to current recommendations.ConclusionsThere are differences in the prevalence of comorbidities and monitoring states of the risk factors between patients in Korea and in other countries. The prevalence of CV morbidity was similar between the two groups although the prevalence of CV risk factors was significantly low in Korea, suggesting that rheumatologists in Korea need to pay more attention to yearly CV risk monitoring, in addition to the screening of malignancy and vaccination of RA patients against infectious diseases.
Recursivity by Organizational Design: The Case of the Forest Stewardship Council
Authors: Malets Olga 
Published: March 2017

AbstractThis article examines recursive processes in the Forest Stewardship Council (FSC), a nonstate forest standard‐setting and accreditation organization. The FSC has developed numerous organizational structures and procedures that help it pool and analyze stakeholder input and feedback in standard‐setting and implementation. We conceptualize recursive processes of stakeholder input and feedback and organizational responsiveness as recursivity by design. The article focuses on organizational legitimacy as a driver of recursive processes. The FSC's extensive participation procedures and structures present opportunities for incorporating stakeholder input and feedback in standard‐setting and make it a responsive, legitimate, and effective governance scheme. It also enables the FSC to deal with challenges to its legitimacy and effectiveness. Whereas challenges associated with stakeholder participation and on‐the‐ground standard implementation are conceptualized in the literature as sources of organizational fragility and crisis, we argue that FSC's recursive structures help it accommodate criticism of and information about its performance and adjust its system to continuously emerging demands for more credibility and quality.

Published: March 2017

AbstractBackgroundIn the absence of the existing acute coronary syndrome (ACS) guidelines directing the clinical practice implementation of emergency department (ED) screening and diagnosis, there is variable screening and diagnostic clinical practice across ED facilities. This practice diversity may be warranted. Understanding the variability may identify opportunities for more consistent practice.MethodsThis is a cross‐sectional clinical practice epidemiology study with the ED as the unit of analysis characterizing variability in the ACS evaluation across 62 diverse EDs. We explored three domains of screening and diagnostic practice: 1) variability in criteria used by EDs to identify patients for an early electrocardiogram (ECG) to diagnose ST‐elevation myocardial infarction (STEMI), 2) nonuniform troponin biomarker and formalized pre‐troponin risk stratification use for the diagnosis of non‐ST‐elevation myocardial infarction (NSTEMI), and 3) variation in the use of noninvasive testing (NIVT) to identify obstructive coronary artery disease or detect inducible ischemia.ResultsWe found that 85% of EDs utilize a formal triage protocol to screen patients for an early ECG to diagnose STEMI. Of these, 17% use chest pain as the sole criteria. For the diagnosis of NSTEMI, 58% use intervals ≥4 hours for a second troponin and 34% routinely risk stratify before troponin testing. For the diagnosis of noninfarction ischemia, the median percentage of patients who have NIVT performed during their ED visit is 5%. The median percentage of patients referred for NIVT in hospital (observation or admission) is 61%. Coronary CT angiography is used in 66% of EDs. Exercise treadmill testing is the most frequently reported first‐line NIVT (42%).ConclusionOur results suggest highly variable ACS screening and clinical practice.
