Authors: Wu Jun , Ni Fenglei , Zhang Yuanfei , Fan Shaowei , Zhang Qi , Lu Jiayuan , Liu Hong 
Published: June 2018

Purpose
This paper aims to present a smooth transition adaptive hybrid impedance control for compliant connector assembly.

Design/methodology/approach
The dynamics of the manipulator is firstly presented with linear property. The controller used in connector assembly is inspired by human operation habits in similar tasks. The hybrid impedance control is adopted to apply force in the assembly direction and provide compliance in rest directions. The reference trajectory is implemented with an adaptive controller. Event-based switching strategy is conducted for a smooth transition from unconstrained to constrained space.

Findings
The method can ensure both ideal compliance behaviour with dynamic uncertainty and a smooth transition from unconstrained to constrained space. Also, the method can ensure compliant connector assembly with a good tolerance to the target estimation error.

Practical implications
The method can be applied in the connector assembly by “pushing” operation. The controller devotes efforts on force tracking and smooth transition, having potential applications in contact tasks in delicate environment.

Originality/value
As far as the authors know, the paper is original in providing a uniform controller for improving force and position control performance in both unconstrained and constrained space with dynamic uncertainty. The proposed controller can ensure a smooth transition by only adjusting parameters.
Comprehensive evaluation of the financial performance for intermediary institutions based on multi-criteria decision making method
Authors: Aras Guler , Tezcan Nuray , Kutlu Furtuna Ozlem 
Published: June 2018

Purpose
The purpose of this paper is to assess the financial performance of the intermediary institutions that have operated in the Turkish capital markets taking the issue of bank-origin and non-bank-origin institutions into account.

Design/methodology/approach
Financial performance of the intermediary institutions has been measured by the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method between the years 2005 and 2016. In order to implement the TOPSIS method, the relative importance of financial performance indicators has been determined by Entropy, survey results and considering equal weights approaches.

Findings
Empirical findings indicate that the average performances of continuously operating intermediary institutions during the concerned period are above the average performance levels of all intermediaries. Additionally, the average rank of bank-origin intermediary institutions have been found higher than the non-bank origins for all years. This reveals that the average financial performance of the bank-origin intermediary institutions is higher than the average score of non-bank origins during the related years.

Originality/value
This study is unique in terms of evaluating the performance of intermediary institutions in Turkish capital markets with a comprehensive framework. Determining the relative importance of financial performance indicators according to entropy, survey results and equal-weight approaches and revealing the average financial performance ranking methodology for bank-origin and non-bank-origin intermediary institutions have added value.

Authors: Palm Kristina , Hansson Johan 
Published: June 2018

Purpose
The purpose of this paper is to address the concept of participatory research (PR) in terms of its values and challenges in project work.

Design/methodology/approach
A participative research approach was used in which researchers worked collaboratively with key stakeholders involved in the development of a digital network model for expert diagnostics. The approach involved research and data gathering in six work packages: first, participation at workshops, including the presentation of a preliminary research agenda; second, presentation of a revised research agenda; third, interviews with project managers and steering committee members; fourth, feedback sessions; fifth, participation at a project conference, including additional feedback sessions; and sixth, concluding interviews with project managers.

Findings
The findings suggest that PR might strengthen project work through challenging interview questions and clear feedback. PR might empower the project manager by illuminating challenges and possibilities in the project process.

Practical implications
Project managers may use PR as one strategy to empower project work.

Originality/value
Despite the vast research on projects and project management, researchers and practitioners are still looking for ways to advance project work. This paper contributes with knowledge on how PR may advance project work.
Performance analysis in emergency departments: a data-driven approach
Authors: Stefanini Alessandro , Aloini Davide , Benevento Elisabetta , Dulmin Riccardo , Mininno Valeria 
Published: June 2018

PurposeThis paper aims to investigate the process performances in Emergency Departments (EDs) with a novel data-driven approach, permitting to discover the entire patient-flow, deploy the performances in term of time and resources on the activities and flows and identify process deviations and critical bottlenecks. Moreover, the use of this methodology in real time might dynamically provide a picture of the current situation inside the ED in term of waiting times, crowding, resources, etc., supporting the management of patient demand and resources in real time.Design/methodology/approachThe proposed methodology exploits the process-mining techniques. Starting from the event data inside the hospital information systems, it permits automatically to extract the patient-flows, to evaluate the process performances, to detect process exceptions and to identify the deviations between the expected and the actual results.FindingsThe application of the proposed method to a real ED revealed being valuable to discover the actual patient-flow, measure the performances of each activity with respect to the predefined targets and compare different operating situations.Practical implicationsStarting from the results provided by this system, hospital managers may explore the root causes of deviations, identify areas for improvements and hypothesize improvement actions. Finally, process-mining outputs may provide useful information for creating simulation models to test and compare alternative ED operational scenarios.Originality/valueThis study responds to the need of novel approaches for monitoring and evaluating processes performances in the EDs. The novelty of this data-driven approach is the opportunity to timely connect performances, patient-flows and activities.
Gender and leadership stereotypes theory: is it reaching the boundaries?
Authors: Vasconcelos Anselmo Ferreira 
Published: June 2018

Purpose
This paper aims to answer whether the notion of the gender and leadership stereotypes theory has already reached its boundaries.

Design/methodology/approach
To accomplish such a goal, it relies on the extant literature looking for more robust findings, problems, disruptions and pathways toward building a better understanding of this problematic.

Findings
The evidence gleaned throughout this paper suggests that the interplay between gender and leadership stereotypes theory has reached its boundaries. Moreover, the traditional sex stereotype or gender traits approach within companies seems to be highly limited taking into account that it tends to nurture rivalry and prejudice among people of different genders. Rather than focusing on leader sex approach or egalitarian quotas, in terms of leadership role and despite the fair argument of diversity, the author proposes that it is wiser to concentrate on a meritocratic view.

Practical implications
It suggests that an androgyny leadership style appears to be welcomed in organizations, yet some shift about this understanding may be occurring. At present, however, female aspirants of leadership roles should work increasingly toward adapting themselves to this profile. In doing so, it is likely that they may be benefited from organizational evaluations in which the merit issue constitutes an imperative.

Originality/value
Overall, it is expected to contribute to theory by arguing that the traditional understanding of gender and leadership stereotypes theory is not suitable anymore to deal with the uncertainties and complexities that shape today’s business arenas. On the contrary, it argues that such approach tends only to encourage gender bias and to nurture a somewhat sex war game in detriment of organizations efficiency and productivity.

Published: June 2018

Purpose
This study aims to find the model fit to understand the consumer behavior in context to the hyper-personalization through digital clienteling by using structural equation modeling. The traditional method of customer passive observance has been transformed to dominance, where, the fundamental challenge for companies is to understand consumer behavior, work on cost-efficiency and implement sustainable innovation.

Design/methodology/approach
To investigate this emerging issue, this study aims to find the model fit via applying “Technology Acceptance Model” (TAM) and “Theory of Reasoned Action” (TRA) in context to the hyper-personalization through digital clienteling with special reference to women ethnic fashion wear.

Findings
The study findings depict the perceived ease of use (PEOU) and perceived usefulness (PU) of technology, attitude toward clienteling and subjective norm toward customization impact on customer intensions. The findings posited that perceived usefulness is having the strong relationship with purchase intention as compare to other variables. So, the analysis postulated that customer considered hyper-personalization is having perceived usefulness for customer and it also helps customer in getting the information about the product on the Web page.

Research limitations/implications
Because of lack of availability of resources, a specified sampling method has been used for this study. A new research, which will cover the fashion apparel from all the categories with a detailed study from the branded and non-branded point of view, will provide better description on this topic.

Practical implications
By having personalized Web page through big data analytics, customer will have positive experience and positive association with the company. The other parameters also play an important role toward the customer behavioral intention. The current study approaches new way of understanding the participative management of the personalization and tool to guide the work of strategy professionals and management of fashion e-commerce sector internationally and even in the other sectors also.

Social implications
Because of advancement of technology, the usage of online media is increasing day by day and this change is having high impact on the society, though we can innovate in any field or industry. Hyper-personalization has an impact on the online consumer buying behavior, which will affect the methods of searching information for consumers.

Originality/value
This new area of research is having large scope of future research from the fashion industry point of view. This paper is working as one of the element in the area of hyper-personalization through digital clienteling to gain sustainable results in the fashion industry.

ObjectiveOur goal was to develop a tele‐colposcopy platform for primary‐care clinics to improve screening sensitivity and access. Specifically, we developed a low‐cost, portable Pocket colposcope and evaluated its performance in a tertiary healthcare centre in Peru.Design and settingImages of the cervix were captured with a standard‐of‐care and Pocket colposcope at la Liga Contra el Cáncer in Lima, Peru.PopulationTwo hundred Peruvian women with abnormal cytology and/or human papillomavirus positivity were enrolled.MethodsImages were collected using acetic acid and Lugol's iodine as contrast agents. Biopsies were taken as per standard‐of‐care procedures.Main outcome measuresAfter passing quality review, images from 129 women were sent to four physicians who provided a diagnosis for each image.ResultsPhysician interpretation of images from the two colposcopes agreed 83.1% of the time. The average sensitivity and specificity of physician interpretation compared with pathology was similar for the Pocket (sensitivity = 71.2%, specificity = 57.5%) and standard‐of‐care (sensitivity = 79.8%, specificity = 56.6%) colposcopes. When compared with a previous study where only acetic acid was applied to the cervix, results indicated that adding Lugol's iodine as a secondary contrast agent improved the percent agreement between colposcopes for all pathological categories by up to 8.9% and the sensitivity and specificity of physician interpretation compared with pathology by over 6.0 and 9.0%, respectively.ConclusionsThe Pocket colposcope performance was similar to that of a standard‐of‐care colposcope when used to identify precancerous and cancerous lesions using acetic acid and Lugol's iodine during colposcopy examinations in Peru.Tweetable abstractThe Pocket colposcope performance was similar to that of a standard‐of‐care colposcope when identifying cervical lesions.
A new paradigm for retrieval medicine
Authors: Moloney John 
Published: June 2018

AbstractA number of new time critical medical interventions are highly specialised. As such, they are not available in many hospitals and EDs. This necessitates transfer to another facility, which is often associated with some degree of delay. Processes to facilitate timely access to these interventions should aim to replicate or improve on that which would have been available should the patient have been in the community, and responded to, primarily, by an emergency medical service.
Permeable Gas Cavity at Elevated Pressure Enhances Modified Atmosphere Packaging of Fresh Produce
Authors: Boz Ziynet , Welt Bruce A. 
Published: June 2018

AbstractModified atmosphere packaging (MAP) of fresh produce involves exploiting package properties to satisfy respiration activity of produce. While effective, package material properties are not infinitely adjustable to match needs of all products. Additional ways of providing favorable in‐package gaseous environments are needed. This work explores the use of permeable inserts filled with gas at elevated pressures as a means to achieve in‐package gaseous atmospheres that may not be possible by the package alone. Mathematical models were developed to predict transient package atmospheres for packages containing respiring produce and pressurized permeable inserts. The model was validated for semirigid tray packages containing grape tomatoes and Granny Smith apples. With inserts initially pressurized with oxygen at approximately 200 to 300 kPa (about 30 to 45 psi), about 2 weeks additional shelf life was observed relative to controls for both tomatoes and apples in test packages. Additionally, simulations provide design guidance for pressurized inserts for the case of very high respiration rate produce such as spinach.Practical ApplicationThis work promises to expand application of modified atmosphere packaging (MAP). Currently, applications are limited by gas transfer material properties of existing packaging films. However, packaging offers other important functions that may not be well served by materials that satisfy critical gas permeation requirements. This work demonstrates an approach that disconnects packaging material specifications from MAP design.

BackgroundCipatinib is a novel tyrosine kinase inhibitor against both EGFR and HER2/neu. This phase I trial was conducted to assess the safety, dose‐limiting toxicities (DLTs), and maximum‐tolerated dose of cipatinib in HER2‐positive patients with advanced breast cancer.MethodsEligible adults with advanced breast cancer were administered cipatinib 200 mg/day (n = 3) as an initial dose, with escalating dosages of 400 mg (n = 4), 800 mg (n = 2), 1200 mg (n = 3), 1400 mg (n = 3), 1600 mg (n = 3), and 1800 mg (n = 2) in 21 day cycles. DLTs were monitored until the end of cycle 2. Physical examinations, vital signs, blood sampling for hematology, clinical chemistry, and pharmacokinetics were performed throughout the trial.ResultsOf the 26 subjects enrolled, 23 completed the trial. A total of 143 adverse events (AEs) were reported, of which 87 were associated with cipatinib treatment and comprised: neutropenia (38%), hypertriglyceridemia (15%), fatigue (15%), nausea (12%), fever (19%), and myocardial ischemia (19%). Six AEs were graded 3–4 (neutropenia, increases in aspartate aminotransferase, and total bilirubin, fatigue, dizziness and nodal tachycardia), but none of the AEs observed were considered to be DLTs.ConclusionThis tolerability study revealed that despite a mild toxicity profile, cipatinib was well tolerated up to the anticipated maximum dosage of 1800 mg/m2. Further clinical trials are warranted.
The Complementarity between Tax Avoidance and Manager Diversion: Evidence from Tax Haven Firms
Authors: Atwood T. J. , Lewellen Christina 
Published: June 2018

ABSTRACTWe investigate whether tax avoidance and manager diversion are complementary when the costs of diversion are low by comparing dividend payouts, performance, and overinvestments of tax haven firms versus other multinational firms based in countries with weak and strong investor protections. Desai and Dharmapala (2006, 2009a, b) and Desai et al. (2007) set forth a theory of tax avoidance within an agency framework (the D&D theory) based on the assumption that tax avoidance and manager diversion are complementary when the corporate governance system is “ineffective” (i.e., the manager's expected costs of diversion are low). Tax haven firms are corporate groups whose parent firms are incorporated in tax haven countries that are not the countries where the groups’ headquarters or primary operations are located (i.e., their “base” countries). We argue that tax haven incorporation potentially lowers the costs of diversion for managers of firms based in countries with weak investor protections. Using a sample from 28 base countries, we provide evidence that manager diversion and tax avoidance are complementary for tax haven firms based in countries with weak investor protections but not for tax haven firms based in countries with strong investor protections. Our results are consistent with the complementarity assumption underlying the D&D model and provide additional insights into the potential impact of the decentralization of the global firm.

Authors: Ng Suat Chin , Stupart Douglas , Bartolo David , Watters David 
Published: June 2018

BackgroundThe purpose of this study was to determine the anastomotic leak rate for colorectal cancer resections in patients with metastases (compared to those without), and to determine the impact of anastomotic leaks on survival.MethodsThis is a retrospective analysis of all patients who underwent resection and primary anastomosis for colorectal adenocarcinoma at a single institution between January 2002 and December 2014.ResultsA total of 843 patients underwent a resection and primary anastomosis for colorectal adenocarcinoma (661 colon and 182 rectal). Of these, 135 (16%) had metastases and 708 (84%) did not. Anastomotic leaks occurred in 17 of 135 (13%) patients with metastases, and in 37 of 798 (5.2%) patients without metastases (P = 0.003). Peri‐operative mortality occurred in 13 of 135 (9.6%) patients with metastases, compared with 19 of 708 (2.7%) patients without metastases (P = 0.0003). Anastomotic leak was associated with a reduction in overall survival (median survival 121 months without anastomotic leak versus 66 months in patients who had an anastomotic leak (P = 0.02)). If the patients who died peri‐operatively are excluded from this analysis, however, long‐term mortality was similar (125 months versus 101 months; P = 0.70).ConclusionMetastatic disease was associated with an increased risk of anastomotic leak and a higher peri‐operative mortality rate after colorectal resections for cancer. Patients with anastomotic leaks had a higher peri‐operative mortality rate, but long‐term survival was unaffected beyond the peri‐operative phase.

Published: June 2018

BackgroundPelvic exenteration (PE) for locally advanced pelvic malignancy requires a multi‐disciplinary approach and is associated with significant morbidity. Urinary reconstruction forms a major component of this procedure. The aim of the study is to review the urological outcomes following PE in a newly established pelvic oncology unit, to compare with those following radical cystectomy (RC) for bladder cancer.MethodsPatients were identified from prospectively maintained PE and bladder cancer databases, inclusive of all cases performed between January 2012 and December 2016. Those without urinary reconstructions and follow‐up durations of less than 3 months were excluded. The outcomes of PE and RC cases were compared, stratifying surgical complications using the Clavien‐Dindo classification. Statistical significance was defined as P < 0.05.ResultsThere were 22 PE cases and 27 RC cases. The median age at surgery was 56 and 65 years, with a median follow‐up of 11.7 and 19.8 months, in the PE and RC groups, respectively. Urinary reconstructions comprised n = 20 (91%) conduit diversions and n = 2 (9%) ureteral reimplantations in the PE group, and n = 5 (19%) orthotopic bladder substitutes and n = 22 (81%) ileal conduits in the RC group. The 30‐day urological complication rate was 23% in the PE group (n = 4 Clavien‐Dindo Grade 1–2, and n = 1 Grade 3) versus 11% in the RC group (n = 1 Grade 1–2, and n = 2 Grade 3), P = 0.801. There were no Grade 4–5 complications in this series.ConclusionThe urological outcomes following PE in complex pelvic oncology are reasonable and not inferior to those after primary RC alone.
