Case-method teaching: advantages and disadvantages in organizational training
Authors: Radi Afsouran Naghi , Charkhabi Morteza , Siadat Seyed Ali , Hoveida Reza , Oreyzi Hamid Reza , Thornton III George C. 
Published: September 2018

Purpose
The purpose of this paper is to introduce case-method teaching (CMT), its advantages and disadvantages for the process of organizational training within organizations, as well as to compare its advantages and disadvantages with current training methods.

Design/methodology/approach
The authors applied a systematic literature review to define, identify and compare CMT with current methods.

Findings
In CMT, participants get involved with real-world challenges from an action perspective instead of analyzing them from a distance. Also, different reactions of the participants to the same challenge aid instructors to identify the individual differences of participants toward the challenge. Although CMT is still not considered as a popular organizational training method, the advantages of CMT may encourage organizational instructors to further apply it. Improving the long-term memory, enhancing the quality of decision making and understanding the individual differences of individuals are the advantages of CMT.

Research limitations/implications
A lack of sufficient empirical researchers and the high cost of conducting this method may prevent practitioners to apply it.

Originality/value
The review suggested that CMT is able to bring dilemmas from the real world into training settings. Also, it helps organizations to identify the individual reactions before they make a decision.
Stock liquidity and free float: evidence from the UK
Authors: El-Nader Ghaith 
Published: September 2018

Purpose
The purpose of this paper is to investigate the interactions between free float and stock liquidity in the UK stock market over the period 2002–2016.

Design/methodology/approach
This paper is conducted using cross-sectional data regression analysis. The sample consists of 15,650 firm-level observations from the UK stock market.

Findings
The findings suggest that stocks with higher levels of free float are associated with higher levels of liquidity. This relation is significant regardless of the liquidity measure used, and is evident even after controlling for firm characteristics.

Originality/value
This paper contributes to the existing literature by presenting further evidence on the significance of free float in capital markets and its effect on stock liquidity, particularly for UK firms as the minimum free float requirements as announced by the FTSE group in 2011 increased from 15 to 25 percent.
Impact of Brownian motion and thermophoresis on bioconvective flow of nanoliquids past a variable thickness surface with slip effects
Authors: K. Anantha Kumar , V. Sugunamma , N. Sandeep , J.V. Ramana Reddy 
Published: September 2018

Purpose
The purpose of this paper is to scrutinize the heat and mass transfer attributes of three-dimensional bio convective flow of nanofluid across a slendering surface with slip effects. The analysis is carried out subject to irregular heat sink/source, thermophoresis and Brownian motion of nanoparticles.

Design/methodology/approach
At first, proper transmutations are pondered to metamorphose the basic flow equations as ODEs. The solution of these ODEs is procured by the consecutive application of Shooting and Runge-Kutta fourth order numerical procedures.

Findings
The usual flow fields along with density of motile microorganisms for sundry physical parameters are divulged via plots and scrutinized. Further, the authors analyzed the impact of same parameters on skin friction, heat and mass transfer coefficients and presented in tables. It is discovered that the variable heat sink/source parameters play a decisive role in nature of the heat and mass transfer rates. The density of motile microorganisms will improve if we add Al-Cu alloy particles in regular fluids instead of Al particles solely. A change in thermophoresis and Brownian motion parameters dominates heat and mass transfer performance.

Originality/value
To the best of the knowledge, no author made an attempt to investigate the flow of nanofluids over a variable thickness surface with bio-convection, Brownian motion and slip effects.
Nanofluid flow and heat simultaneously induced by two stretchable rotating disks using Buongiorno’s model
Authors: Muthtamilselvan M. , Renuka A. 
Published: September 2018

Purpose
The purpose of this paper is to investigate the nanofluid flow and heat transfer induced by two co- axially rotating disks using Buongiorno’s model. This model took into account the Brownian diffusion and thermophoresis effects due to the presence of nanoparticles.

Design/methodology/approach
The governing partial differential equation was transformed into a set of nonlinear ordinary differential equations by using similarity transformation and solved numerically using shooting techniques.

Findings
The present work is a comparison study of Maxwell-Garnett model and modified Maxwell model for the effective thermal conductivity of nanofluids. The effects of different involved parameters on velocity and temperature profile are examined graphically. Numerical values of skin friction coefficient and Nusselt number are computed and studied.

Originality/value
It is found that the results of azimuthal velocity profile are an increasing function of upper disk stretching parameter. The radial and axial velocity profile is enlarged for a large value of lower stretching parameter. Fluid temperature decays for large values Reynolds number and lower disk stretching parameter.
Tattoos in policing: a survey of state police policies
Authors: McMullen Sara M. , Gibbs Jennifer 
Published: September 2018

Purpose
Policing agencies across the USA have cited difficulty recruiting qualified applicants, thus leaving many employment vacancies unfilled. One reason for this challenge may be that those who would make exceptional police officers are barred from employment because of their body art. Varying appearance policies exist concerning tattoos, yet little is known about these policies. The purpose of this paper is to survey the tattoo policies of policing agencies.

Design/methodology/approach
The tattoo policies of all 50 state-level policing agencies were reviewed to explore similarities and state-level correlates.

Findings
The majority, but not all, of state police have some type of appearance policy targeting tattoos. State policing agencies that have a “no visibility” policy regarding tattoos more often were in states with a low percentage of millennial residents, high percentage of young veterans, men and non-Hispanic white citizens, and low crime; t-tests indicate “no visibility” policy states significantly differed from other states in the percentage of non-Hispanic whites and crime. Further, state policing agencies with a “no visibility” policy tended to be in northeastern states, with southern states having the fewest state policing agencies with such policies, although the χ2 test was non-significant.

Originality/value
Despite the ubiquity of tattoos in the American society, the literature is scant with studies of police appearance policies regarding tattoos. This study provides a partial summary of tattoo policies at the state policing level.
What influences organisational evolution of modern sport: the case of skateboarding
Authors: Batuev Mikhail , Robinson Leigh 
Published: September 2018

PurposeThe purpose of this paper is to investigate the processes that influence the evolution of a modern sport. It focusses on the case of international skateboarding: the sport that was recently included into the Olympic Games.Design/methodology/approachAn inductive research strategy was informed by the notions of evolution of modern sport, prolympism and new institutionalism. The primary data were collected through a series of interviews and supplemented by the analysis of documents, press and social media.FindingsThe paper analysed how the organisation of international skateboarding has changed to date and identified three major determinants of its evolution: values of the activity, commercial interests and the Olympic movement. The following recurring discussion themes emerged: the link between commercialism and legitimisation of sport; bureaucratisation under the Olympic movement; and tensions between prolympism and values of skateboarding.Research limitations/implicationsA limitation of the case study method is that any conclusions refer to this particular sport and their applicability to other sports lies within analytical generalisation. Still sport governing bodies and policy makers can learn from the evolution of international skateboarding and analyse potential issues and consequences for other emerging sports. In terms of theoretical implications, the study highlights legitimisation as one the key characteristics of evolution of modern sport, which should be considered along with previously established criteria, such as bureaucratisation, commercialisation and professionalisation.Originality/valueThe study extends the existing research on evolution of modern sports by examining a very rich contemporary case of skateboarding, the internationally growing sport with unique organisational arrangements. It contributes to knowledge of the evolution towards legitimisation of emerging sports, but also towards sportification of popular culture and society.
The role of UTAUT, DOI, perceived technology security and game elements in internet banking adoption
Authors: Rahi Samar , Abd. Ghani Mazuri 
Published: September 2018

Purpose
The increasing innovation and urgent need of up-to-date and convenient information systems have gained high importance in financial sector. Several banks have deployed internet banking in order to reduce cost while improving customer services. Therefore, the growth of internet banking is limited and in many cases fallen short of expectations. The purpose of this paper is to develop an integrated model that combines technology, innovative and environmental factors altogether in order to understand customer’s intention to adopt, and intention to recommend internet banking in social networks.

Design/methodology/approach
In all, 398 valid responses were collected from customers of commercial banks, using convenience sampling approach. Data were analyzed using the structural equation modeling.

Findings
The findings show that integrated model has good explanatory power (78.3 percent) to predict customer’s intention to adopt internet banking. Findings also revealed that the interaction effect of gamification between user’s intention to adopt and user’s intention to recommend internet banking will be stronger when gamification effect is higher. Importance performance matrix analysis (IPMA) revealed that innovativeness and perceived technology security were the most important factors in order to determine user’s intention with regard to adoption of internet banking.

Practical implications
For policy-makers, it is suggested that they should focus on innovative characteristics and must ensure the possible environment for carrying out internet banking transaction. Advertising about new technology with adequate information may produce positive influence on user’s intention. Enjoyable internet banking website with reward system will help to improve user’s intention to adopt and intention to recommend internet banking with others, thus developers should introduce game features on internet banking website.

Originality/value
This study provides basis for further refinement of individual technology acceptance models and enrich the e-commerce literature adding innovative and game elements in interne banking adoption context. Additionally, the proposed model makes an important contribution in emerging e-commerce literature especially in the context of innovative and gamified internet banking.
America Gerrymanders on—For the Moment?
Authors: Johnston Ron 
Published: September 2018

AbstractGerrymandering has long characterised the electoral cartography of the United States and a sequence of cases seeking to outlaw the practice have all failed before the Supreme Court. Its judgement in a 2006 case indicated that although the Court recognised the practice, it could identify no formal means of evaluating whether any particular map of Congressional or State electoral districts was a gerrymander that violated a constitutional provision. This encouraged those who drew up new district maps in many states after publication of the 2010 census data, most of which favoured the Republican party and were more egregious than previous such cartographies. A minority judgement in that case did suggest ways in which a gerrymander could be proved, however, and these were followed in a case brought regarding new State Assembly districts for Wisconsin. A lower court found in favour of the plaintiffs but this was over‐turned by a unanimous Supreme Court which found that the plaintiffs had no standing to challenge a state‐wide map. A concurrent decision by a minority of the Justices did suggest ways in which standing could be established and gerrymanders countered, and this may stimulate further cases—although it is uncertain whether a majority on the Court will accept such arguments. Meanwhile, America gerrymanders on.
Institutions as constraints and resources: Explaining cross‐national divergence in performance management
Authors: Doellgast Virginia , Marsden David 
Published: September 2018

AbstractThis article compares performance management practices in call centres from four telecommunications firms in the United Kingdom, France, Denmark, and Germany. Findings show that different combinations of institutional constraints, such as strong job security protections, and participation resources supporting worker voice were influential in shaping choices among policies to motivate and discipline workers. Performance management most closely approached a high‐involvement model where both constraints and resources were high, where worker representatives were able both to restrict management's use of sanctions and to establish procedures that improved the perceived fairness of incentives. Findings contribute to debates concerning the role of contextual factors in the design and effectiveness of HRM.
Linking of metabolomic biomarkers with cardiometabolic health in Chinese population
Authors: Sun Liang , Li Huaixing , Lin Xu 
Published: September 2018

AbstractDue to rapid nutrition transitions, the prevalence of cardiometabolic diseases, such as metabolic syndrome, type 2 diabetes, and cardiovascular diseases, has been increasing at an alarming rate in the Chinese population. Moreover, Asians, including Chinese, have been hypothesized to have a higher susceptibility to cardiometabolic diseases than Caucasians. Early prediction and prevention are key to controlling this epidemic trend; to this end, the identification of novel biomarkers is critical to reflect environmental exposure, as well as to reveal endogenous metabolic and pathophysiologic mechanisms. The emerging “omics” technologies, especially metabolomics, offer a unique opportunity to provide novel signatures or fingerprints to understand the effects of genetic and non‐genetic factors on cardiometabolic health. During the past two decades, metabolomic approaches have been increasingly used in various epidemiological studies, primarily in Western populations. Although the field is still in its early stages, some studies have tried to identify novel compounds or confirm their metabolites and associations with cardiometabolic diseases in Chinese populations, including amino acids, fatty acids, acylcarnitines and other metabolites. Despite major efforts to discover novel biomarkers for disease prediction or intervention, the limits in current study design, analytical platforms, and data processing approaches are challenges in metabolomic research worldwide. Therefore, future research with more advanced technologies, rigorous study designs, standardized detection and analytic approaches, and integrated data from multiomics approaches are essential to evaluate the feasibility of using metabolomics in clinical settings. Finally, the functional roles and underlying biological mechanisms of metabolomic biomarkers should be elucidated by future mechanistic research.
Ventilation perfusion single photon emission computed tomography: Referral practices and diagnosis of acute pulmonary embolism in the quaternary clinical setting
Authors: Lawrence Natalie C , Kyle Samuel 
Published: September 2018

AbstractIntroductionVentilation perfusion single photon emission computed tomography (V/Q SPECT) and CTPA are the two leading imaging studies used to investigate acute pulmonary embolism. V/Q SPECT is often the first line investigation for pregnant patients and young females. Historically, V/Q Planar studies have high rates of indeterminate findings resulting in a preference for CTPA studies. The purpose of this research is to examine current V/Q SPECT referral practices in the quaternary clinical setting and to confirm V/Q SPECT studies have low rates of equivocal findings.MethodsRetrospective study of a 6‐month period of all completed V/Q SPECT studies (± LDCT) indicated for investigation of acute PE. V/Q SPECT studies were reported using the European Association of Nuclear Medicine guidelines. Patient demographic data and V/Q SPECT findings were recorded. CTPA and Doppler Ultrasound report findings were included if performed 48 hours prior to, or following V/Q SPECT study. Standard descriptive statistical analysis was undertaken.ResultsNinety‐nine percent of V/Q SPECT studies had reports positive or negative for acute PE, with 1% inconclusive. Twenty‐two percent of patients had either CTPA or Doppler Ultrasound studies within a 48‐ hour period prior to, or following V/Q SPECT, with the majority having a negative Doppler ultrasound prior to negative V/Q SPECT. Sixty‐eight percent of patients referred for V/Q SPECT were females under the age of 55, 40% of whom were pregnant.ConclusionsVentilation perfusion single photon emission computed tomography has low rates of equivocal findings with referral practices indicating pregnant patients and young women are considered to most benefit from V/Q SPECT as a first line investigation for acute PE.

Published: September 2018

AbstractPurposeStudy purpose was to investigate the effects of bariatric surgery on intraocular pressure (IOP) and other ophthalmic parameters in a prospective observational follow‐up study.MethodsOphthalmic examination was performed on 22 obese women before and 6 months after bariatric surgery. A control group of 15 non‐obese age‐matched women were studied twice 6 months apart. IOP was measured with the Goldmann applanation tonometer (GAT) and the Pascal dynamic contour tonometer (PDCT). None of the subjects had glaucoma.ResultsAverage weight loss 6 months after bariatric surgery was 25 ±8 kg, (p < 0.05). Visual acuity (VA), pachymetry and systolic as well as diastolic blood pressures did not differ between the obese and control groups and no change between the visits was detected. At baseline, IOP was significantly higher in the obese group than in the controls (16.6 ± 3.0 mmHg GAT and 18.1 ± 2.2 mmHg PDCT compared with 14.3 ± 1.5 mmHg GAT and 16.5 ± 1.9 mmHg PDCT respectively). After bariatric surgery, IOP was significantly lower (15.2 ± 2.7 mmHg GAT and 16.5 ± 2.0 mmHg PDCT, p < 0.05) and no significant difference was detected between the operated and control groups. In the whole data at baseline, IOP correlated with weight, body mass index, waist circumference, body fat per cent and systolic blood pressure values.ConclusionIntraocular pressure (IOP) is significantly higher in obese women than in non‐obese age‐matched controls. Obese subjects had a decrease in IOP after bariatric surgery with no change in IOP in the control group. This change in obese group may be related to weight loss. Different measures of obesity correlated with IOP at baseline.

AbstractPurposeTo measure the Schlemm's canal (SC) in vivo by Fourier‐domain optical coherence tomography (FD‐OCT) in a Caucasian paediatric population.MethodsParticipants of this cross‐sectional study were 290 healthy children. In the right eye of each child, SC cross‐sectional diameter and area measurements were made with the FD‐OCT instrument RTVue® (Optovue Inc, Fremont, CA, USA) in the nasal and temporal quadrants. These SC variables were then assessed for correlation with the factors age, gender, refractive error, anterior chamber angle and trabecular meshwork (TM) metrics. Finally, the reproducibility of the SC measurements was assessed in 30 of the participants.ResultsMean participant age was 10.7 ± 3.4 years (range 3–18). SC diameters could be measured in both quadrants in 70.6% and 70.4% of subjects, respectively. Mean SC diameters were similar (p = 0.125) for the temporal and nasal quadrants: 266.7 ± 84.1 μm (range 131–509) and 273.2 ± 77.3 μm (range 124–486), respectively. Mean SC areas were also similar (p = 0.167) for the two quadrants: 9975 ± 3514 μm2 (range 4000–23 000) versus 9688 ± 3297 μm2 (range 3000–24 000). No differences were detected in SC measurements according to gender, refractive error or angle and TM measurements (R ≤ 0.116; p ≥ 0.125). The exception was age which was directly correlated with SC size (p ≤ 0.041). The reproducibility of the SC measurements was excellent (intraclass correlation coefficients ≥0.936).ConclusionFD‐OCT allows the identification of the SC in children. Our data indicate an increase in SC size produced with age.
Baseline visual acuity as a prognostic factor for visual outcomes in patients treated with aflibercept for wet age‐related macular degeneration: data from the INSIGHT study using the Swedish Macula Register
Authors: Lövestam Adrian Monica , Vassilev Zdravko P. , Westborg Inger 
Published: September 2018

AbstractPurposeTo assess mean change in visual acuity (VA) overall and stratified by baseline VA after 1 and 2 years’ treatment with aflibercept in a real‐life setting.MethodsThis was an observational cohort study using nationwide data from the Swedish Macula Register. Treatment‐naïve patient eyes with wet age‐related macular degeneration and prescribed aflibercept from January 2013 to December 2014 were followed for 1 year (2478 eyes) or 2 years (831 eyes) to assess VA. Eyes were grouped by baseline VA.ResultsMean number of injections in patients treated according to label (72%) versus patients treated not according to label was 8.0 ± 1.5 versus 4.4 ± 0.8 (p < 0.0001) at 1 year, and 12.5 ± 3.2 versus 7.3 ± 1.9 (p < 0.0001) at 2 years. Among all eyes, mean VA increased from 61.3 ± 13.4 Early Treatment Diabetic Retinopathy Study letters at baseline to 64.5 ± 15.6 at 1 year and 65.1 ± 15.1 letters at 2 years. At 2 years, eyes with good baseline vision (≥70 letters) lost a mean of 2.4 ± 11.3 to 72.3 letters, eyes with intermediate baseline VA (36–69 letters) gained 5.7 ± 14.1 to 62.7 letters, and eyes with poor baseline VA (≤35 letters) gained 13.2 ± 18.3 to 41.0 letters. Also at 2 years, 75% of treated eyes were stable or had improved VA. Among eyes with intermediate baseline VA, near vision was significantly better among those treated according to label versus not according to label at 3 (p = 0.019), 6 (p = 0.0002) and 12 months (p ≤ 0.0001).ConclusionWhile gain in vision was especially pronounced in eyes with poor baseline VA, good baseline VA was important for best prognosis.
