Authors: Sharoky Catherine E. , Sellers Morgan M. , Keele Luke J. , Wirtalla Christopher J. , Karakousis Giorgos C. , Morris Jon B. , Kelz Rachel R. 
Published: July 2017

Objective:
We sought to compare postoperative outcomes of female surgeons (FS) and male surgeons (MS) within general surgery.

Summary of Background Data:
FS in the workforce are increasing in number. Female physicians provide exceptional care in other specialties. Differences in surgical outcomes of FS and MS have not been examined.

Methods:
We linked the AMA Physician Masterfile to discharge claims from New York, Florida, and Pennsylvania (2012 to 2013) to examine practice patterns and to compare surgical outcomes of FS and MS. We paired FS and MS operating at the same hospital using cardinality matching with refined balance and compared inpatient mortality, any postoperative complication, and prolonged length of stay (pLOS) in FS and MS.

Results:
Overall practice patterns differed between the 663 FS and 3219 MS. We identified 2462 surgeons (19% FS, 81% MS) at 429 hospitals who met inclusion criteria for outcomes analysis. FS were younger (mean age ± SD FS: 48.5 ± 8.4 years, MS: 54.3 ± 9.4y; P < 0.001) with less clinical experience (mean years ± SD FS: 11.6 ± 8.3 y, MS: 17.6 ± 10.0 years; P < 0.001) than MS before matching. FS had lower rates of inpatient mortality (FS: 1.51%, MS: 2.30%; P < 0.001), any postoperative complication (FS: 12.6%, MS: 16.1%; P < 0.001), and pLOS (FS: 18.4%, MS: 20.7%; P < 0.001) before matching. After matching, FS and MS outcomes were equivalent.

Conclusion:
Surgeon practice patterns vary by sex and experience. FS and MS with similar characteristics who treat similar patients at the same hospital have equivalent rates of inpatient morality, postoperative complications, and prolonged length of hospital stay. Patients should select the surgeon who is the best fit for them regardless of sex.

Abstract
De novo renal cell carcinoma (RCC) rarely occurs in kidney allografts; however, the risk of RCC in these patients is 100-fold that of the general healthy population. Although total nephrectomy has been the standard treatment for kidney allograft RCC, several authors have reported that early-stage RCC in kidney allografts was successfully treated with nephron-sparing surgery. We herein describe a new procedure involving renal autotransplantation and extracorporeal nephron-sparing surgery, which was performed to treat de novo RCC near the hilum of a transplanted kidney. In the 22 months since transplantation, the patient's renal function has been favorable, and no recurrence has been observed. In conclusion, renal autotransplantation is a feasible technique for the treatment of RCC in kidney allografts, especially RCC located near the hilum.
Temporal expression divergence of network modules
Authors: Park Yongjin , Kang Tae-Hyuk , Friedmann Theodore , Bader Joel S. 
Published: July 2017

AbstractHere we propose new module-based approaches to identify differentially regulated network sub-modules combining temporal trajectories of expression profiles with static network skeletons. Starting from modules identified by network clustering of static networks, our analysis refines pre-defined genesets by partitioning them into smaller homogeneous sets by non-paramettric Bayesian methods. Especially for case-control time series data we developed multi-time point discriminative models and identified each network module as a mixture or admixture of dynamic discriminative functions. Our results shows that our proposed approach outperformed existing geneset enrichment methods in simulation studies. Moreover we applied the methods to neural stem cell differentiation data, and discovered novel modules differentially perturbed in different developmental stages.

Published: July 2017

AbstractThe misfolding and accumulation of tau protein into intracellular aggregates known as neurofibrillary tangles is a pathological hallmark of neurodegenerative diseases such as Alzheimer’s disease. However, while tau propagation is a known marker for disease progression, exactly how tau propagates from one cell to another and what mechanisms govern this spread are still unclear. Here, we report that cellular internalization of tau is regulated by quaternary structure and have developed a cellular assay to screen for genetic modulators of tau uptake. Using CRISPRi technology we have tested 3200 genes for their ability to regulate tau entry and identified enzymes in the heparan sulfate proteoglycan biosynthetic pathway as key regulators. We show that 6-O-sulfation is critical for tauheparan sulfate interactions and that this modification regulates uptake in human central nervous system cell lines, iPS-derived neurons, and mouse organotypic brain slice culture. Together, these results suggest novel strategies to halt tau transmission.
The information of story: the genre and information activities of ultrarunning race reports
Authors: Gorichanaz Tim 
Published: July 2017

Purpose
The purpose of this paper is to explore the “race report” as a document genre in the serious-leisure pursuit of ultrarunning. Despite the sport’s largely non-documental nature, race reports stand as an anomaly in their importance. This exploration serves as a springboard to investigate the informativeness of story in human life generally.

Design/methodology/approach
A qualitative survey of the information behavior of ultrarunners was conducted. The 46 participants were runners in a 100-mile footrace in 2016. Responses were first analyzed through phenomenological theme analysis and then were subjected to a deductive audit using a framework of information activities validated for use in serious-leisure pursuits.

Findings
Race reports are bound up in information activities across the information-communication chain. Race reports help athletes choose races, prepare for races, pre-experience races, communicate their race experiences, gather new ideas, extend their training and, finally, find entertainment.

Research limitations/implications
This discussion of genre is synchronic, largely limited to one moment in time, and its findings were limited in depth by the survey method. Further research should investigate race reports historically (diachronically) and infrastructurally.

Originality/value
This work points to symbiosis between genre theory and information behavior theory. It also legitimizes narrative reasoning as a way of knowing, which has been largely unrecognized in information behavior. Some implications of this for information science and technology are discussed.
A prediction method of material consumption for flat-knitted sweaters
Authors: Luo Xuan , Jiang Gaoming , Cong Honglian 
Published: July 2017

PurposeA method for predicting the material consumption of a sweater is presented before it is knitted. It can be achieved with the five basic models combined with the parameters related to the dimensions of the knitting machine and needles. The paper aims to discuss these issues.Design/methodology/approachBased on the parameters of the needle bar flat knitting machine, the sweater is modeled with five basic structures. The mathematical expression of each basic structure can be derived with corresponding parameters under some consumptions. In following, the predictive weight of the sweater can be formulated with the expression of the length of the basic structures and the linear density of the yarn.FindingsTo evaluate the performance of the proposed scheme, experiments of three types of sweaters on four different knitting machines are carried out. The results show that the proposed method can achieve the performance with the bias values by percentage ranging from −1.54 to −2.84 percent.Research limitations/implicationsDue to the present limited research, more experiments could not be carried out. To improve the performance and robustness of the proposed method, statistical performance measures such as the statistical mean and variance in massive experiments will be studied in the further research.Practical implicationsThe evaluation of the material consumption can be obtained before it is knitted with the known basic parameters related to the machine and yarn.Originality/valueThis paper derives the general expressions of five basic structures based on the corresponding parameters of knitting machine. The predictive weight of the sweater is expressed according to the above basic structures before the sweater is knitted.

Published: July 2017

Purpose
The purpose of this paper is to propose a relatively simple and rapid method to create a digital human model (DHM) to serve clothing industry.

Design/methodology/approach
Human body’s point cloud is divided into hands, foots, head and torso. Then forward modeling method is used to model hands and foots, photo modeling method is used to model head and reverse modeling method is used to model torso. After that, hands, foots, head and torso are integrated together to get a static avatar. Next, virtual skeleton is bound to the avatar. Finally, a lifelike digital human body model is created by the mixed modeling method (MMM).

Findings
In allusion to the defect of the three-dimension original data of human body, this paper presented an MMM, with which we can get a realistic digital human body model with accurate body dimensions. The DHM can well meet the needs of fashion industry.

Practical implications
The DHM, which is got by the MMM, can be well applied in the field of virtual try on, virtual fashion design, virtual fashion show and so on.

Originality/value
The originality of the paper lies in the integration of forward modeling, reverse modeling and photo modeling to present a novel method of human body modeling.
Development and trial of athletic T-shirt using spacer blocks to enhance ventilation
Authors: Ho Chu Po , Fan Jintu , Newton Edward , Au Raymond 
Published: July 2017

Purpose
In previous studies, enlarging the air gap between fabric and the skin through the placement of spacer blocks has been proven to improve air ventilation, particularly when the pumping effect is activated during movement. These studies evaluated only the total thermal insulation (Rt) and moisture vapour resistance (Ret) by using a fabric thermal manikin. The purpose of this paper is to report the experience, perceived comfort level, and ventilation effect of two designed T-shirts in a wearer trial.

Design/methodology/approach
An athletic T-shirt (Vented Design) was designed by attaching spacer blocks to the underside of the fabric to enlarge the air gap. Eight subjects participated in the wearer trial, which comprised 30 min treadmill running, followed by 10 min of rest. At different points during the 40 min test period, subjects rated their body coolness, skin dryness, and overall comfort of the designed T-shirt. The testing was repeated with participants wearing the same T-shirt but without spacer blocks, which served as a control garment. The mean skin temperature of each subject was also measured to support survey findings.

Findings
The data were evaluated using independent t-tests. The T-shirt with spacer blocks provided higher ventilation than the control T-shirt after 10 min of running. Research limitations – because of limited resources, only eight subjects were recruited to this study. In addition, more T-shirt designs should be tested in the future to elucidate how T-shirt design affects ventilation performance.

Originality/value
This study investigated a T-shirt design wherein the air gap between the skin surface and fabric was increased. The results of the wearer trial showed that this design could be adopted as a design brief for further design development of related clothing. This study has implications for clothing designers developing functional clothing with improved ventilation.
Cotton fibre selection and grading – a PROMETHEE-GAIA-based approach
Authors: Chakraborty Shankar , Bandhopadyay Siddhartha 
Published: July 2017

PurposeIn spinning industries, selection of the most appropriate fibre for yarn manufacturing plays an important role for achieving an optimal mix of several yarn characteristics, like maximum tenacity, elasticity and spinning ability; and minimum unevenness and hairiness. Identification of the best suited cotton fibre from a set of available alternatives in presence of different conflicting physical properties is often treated as a multi-criteria decision-making (MCDM) problem. The paper aims to discuss this issue.Design/methodology/approachIn this paper, the preference ranking organisation method for enrichment of evaluations (PROMETHEE) and geometrical analysis for interactive aid (GAIA) methods are integrated to solve a cotton fibre selection problem. The PROMETHEE II method ranks the alternative cotton fibres based on their net outranking flows, whereas GAIA acts as a visual aid to strongly support the derived selection decision. The weight stability intervals for all the considered fibre properties (criteria) over which the position of the top-ranked cotton fibre remains unchanged are also determined.FindingsThe clusters of cotton fibres formed in the developed GAIA plane act as a yard stick for their appropriate grading to aid the blending process. The ranking of 17 cotton fibres as achieved applying the combined PROMETHEE-GAIA approach highly corroborates with the observations of the past researchers which proves its immense potentiality and applicability in solving fibre selection problems.Originality/valueTwo MCDM methods in the form of PROMETHEE II and GAIA are integrated to provide a holistic approach for cotton fibre grading and selection while taking into consideration all the available cotton fibre properties.
Learning challenges and preferred pedagogies of international students
Authors: Rao Pramila 
Published: July 2017

Purpose
The purpose of this paper is to understand the challenges international students face during their higher education in the USA. This research study was conducted at a private university in the Eastern region of the USA from October 2012 through May 2013 (Fall and Spring semesters) with undergraduate and graduate international students. International students for this study are defined as those students who are on an international student visa status (F1).

Design/methodology/approach
This research adopts an online survey method to understand the challenges international students encounter in a single university. A total of 111 students responded providing a response rate of 33 percent. The results were analyzed using frequencies and percentages.

Findings
The findings of this study suggest that the primary learning challenges of international students are inadequate writing skills, non-participation, and comprehension abilities. The predominant learning needs are writing academic papers, enhancing class participation, and having local mentors. The students recommend that professors offer detailed feedback, encourage nurturing environments, and provide informal feedback for assignments. The preferred pedagogies are class lectures, class discussions, and individual assignments.

Practical implications
This study provides implications for both faculty and administrative staff in managing international students better.

Originality/value
This paper provides a holistic picture of the challenges international students face during their higher education in the USA. Most of the research on this population focuses only on one of the elements addressed in this research. The results of this empirical study will help guide both local faculty and global academic institutions in understanding this student population better.
Promoting the school learning processes: principals as learning boundary spanners
Authors: Benoliel Pascale , Schechter Chen 
Published: July 2017

PurposeThe ongoing challenge to sustain school learning and improvement requires schools to explore new ways, and at the same time exploit previous experience. The purpose of this paper is to attempt to expand the knowledge of mechanisms that can facilitate school learning processes by proposing boundary activities and learning mechanisms in which principals can engage to promote learning processes.Design/methodology/approachThe authors refer to Bourdieu’s theoretical approach that human actions occur within fields of interaction. The authors delineate principals’ internal and external boundary activities as mechanisms for promoting school learning processes while acknowledging that principals are embedded within competing fields, encompassing demands from the economic, political, and even global fields. The authors discuss how the principal boundary activities can not only facilitate the exploitation of knowledge embedded in the school system, but also the exploration of external knowledge across multiple fields of interaction. The authors then present the principal learning mechanisms as complementary activities to school learning improvement.FindingsPromoting school learning processes may require constant management of the school learning boundary so that the school neither becomes isolated from its environment nor loses its capacity for knowledge integration and exploitation. The boundary activities, combined with learning mechanisms, can enable the principal to balance these competing demands.Originality/valueThe organizational learning processes of exploration and exploitation have been under-investigated in the educational context, as to the role of the principal in balancing the tension between these processes. This study conceptualizes boundary activities and learning mechanisms, suggesting a framework through which principals can engage to promote school learning.
Developing relationships with school customers: the role of market orientation
Authors: Poole Sonja Martin 
Published: July 2017

Purpose
While the role of relationship marketing to consumers’ overall satisfaction with schools has been discussed in the education management literature, empirical studies on the marketing mechanisms that underpin school-customer relationships are limited. The purpose of this paper is to establish the association between market orientation (MO) in the school context and key relationship marketing performance indicators.

Design/methodology/approach
MO and four relationship constructs (brand trust, affective commitment, attitudinal loyalty, and advocacy) were measured using existing and established scales from the education and behavioral literatures. A model reflecting causal ordering derived from the literature and an understanding of school-customer relationships was developed. Data were collected from 205 parents of school-aged children in the USA and analyzed using structural equation analysis.

Findings
Results show that a positive relationship between market-oriented behaviors of school organizations and three of the identified indicators of successful school relationship marketing (affective commitment, attitudinal loyalty, and advocacy) are mediated by brand trust.

Originality/value
The study contributes to an understanding of the theoretical relationship between market-oriented behaviors and relationship marketing for schools. The results suggest that, for school organizations, MO impacts important outcomes and thus may be vital to sustainability and growth.
International students’ engagement in their university’s social media
Authors: Fujita Momoko , Harrigan Paul , Soutar Geoffrey Norman 
Published: July 2017

Purpose
The purpose of this paper is to understand the lived experiences of the international students using their university’s social media, through a lens of customer engagement (CE) in the services marketing literature.

Design/methodology/approach
A case study was conducted in an Australian university. Three semi-structured focus groups with ten international students, along with a preliminary netnographic analysis of the university’s social media account, provided a rich description of the phenomenon in the real-world context.

Findings
The results suggest that these students are likely to engage in their university’s social media as part of their acculturation and social identity construction strategy. Their engagement was cognitive and emotional, being influenced by the instrumental value of the social media page, engagement with campus rituals and artefacts, social identity and bonds with other students and perceptions of the page administrator. Furthermore, these students’ engagement influenced their identification with the university and its student community, manifested in a sense of belonging and pride.

Research limitations/implications
The paper contributes to the higher education literature by offering relationship implications of social media CE. Limitations include small sample size and the single institutional context.

Practical implications
The paper informs student communication practice, especially the design of university-initiated social media content and policy.

Originality/value
Universities and faculties today use social media to engage with students outside classrooms. However, little has been known about how international student sojourners view and respond to such initiatives. The paper addresses this gap by offering insight into how they engage with their university on social media and its relationship implications.
Fostering learning organisation in transitional economy – the role of authentic leadership and employee affective commitment
Authors: Delić Milan , Slåtten Terje , Milić Bojana , Marjanović Uglješa , Vulanović Srđan 
Published: July 2017

PurposeThe aim of this study is to examinehowand inwhatway authentic leadership and affective employee commitment foster the learning organisation in the context of transitional market conditions. Acting as role factors, their relationships with the learning organisation were examined simultaneously, at leadership and employee level.Design/methodology/approachThe study was conducted on a sample of 500 employees from various industries of Serbian transitional economy. For the research purposes, structural equation modeling (SEM) methodology was used.FindingsThe findings reveal that authentic leadership and employee commitment both play an important role. Specifically, authentic leadership directly and indirectly affects the learning organisation. The indirect effect is partially mediated by the employee affective commitment.Research limitations/implicationsThe focus of this study is limited to the role of authentic leadership in fostering the learning organisation. Apart from leadership and employee commitment, it might be assumed that other variables have the potential to play a role in fostering the learning organisation as well.Originality valueTo the best of the authors’ knowledge, no previous study has focused on authentic leadership and employee commitment as an “enabling-mechanism” in fostering learning organisations in the context of transitional economies. Consequently, this paper provides theoretical and practical implications on how and in what way they impact a learning organisation by empirically studying them in the context of transitional market conditions.
