High Altitude-associated Changes in Intraocular Pressure Abrogated by Trabeculectomy
Authors: Foulsham William , Tatham Andrew J. 
Published: June 2017

Purpose:
To highlight the effect of ascent to high altitude on intraocular pressure (IOP) in a patient with primary open-angle glaucoma, who had previously undergone trabeculectomy in 1 eye.

Methods:
Case report.

Results:
A 66-year-old mountaineer with primary open-angle glaucoma and previous right trabeculectomy performed self-tonometry using a rebound tonometer (Icare HOME) before and during an expedition in the Himalaya. In the nonoperated eye, there was a statistically significant increase in IOP as the patient ascended to 5000 m over 8 days (R
2=0.790, P=0.001), consistent with recent literature. IOP increased by 1.73 mm Hg with each 1000 m increase in altitude. In the trabeculectomized eye there was no significant increase in IOP (R
2=0.219, P=0.172).

Conclusions:
Filtration surgery may be protective against IOP fluctuations associated with ascent to high altitude. Self-tonometry complements standard glaucoma care by providing opportunities for IOP monitoring outside office hours and in remote locations.
Long-term Outcome of Surgical Treatment for Late Intraocular Lens Dislocation Associated With High Intraocular Pressure: A Case Series
Authors: Torres Lucas A. , Vianna Jayme R. , Nicolela Marcelo T. 
Published: June 2017

Purpose:
To demonstrate the long-term safety and efficacy of transscleral intraocular lens (IOL) fixation combined with an Ahmed glaucoma drainage device implantation for patients with late IOL dislocation and high intraocular pressure (IOP).

Methods:
This is a retrospective report of a series of patients who underwent this combined surgery. The main outcome variables studied were change in visual acuity (VA), IOP, and number of medications compared with preoperative levels. Surgical failure was defined as a decrease in VA of at least 3 Snellen lines, IOP above 20 mm Hg or IOP reduction <25% from preoperative levels at ≥2 consecutive visits, at least 2 months apart.

Results:
Eleven patients with median age of 83 years (range, 77 to 92 y) were included in the study. All patients had a previous diagnosis of pseudoexfoliation. After a median follow-up time of 1.75 years (range, 0.83 to 2.5 y), the median IOP decreased from 33 mm Hg (range, 24 to 47 mm Hg) to 13 mm Hg (range, 5 to 16 mm Hg; P<0.01). The number of glaucoma medications also decreased from 3 (range, 1 to 4) to 2 (range, 0 to 4; P=0.03). The median log MAR VA improved from 0.77 (range, 0.3 to 2) preoperatively to 0.44 (range, 0 to 3) postoperatively (P=0.27).
Four patients had postoperatory surgical complications: choroidal effusion (2), vitreous hemorrhage and hyphema (1), vertical diplopia (1). The survival probability over 2.5 years was 90.9% (confidence interval, 75.4%-100%).

Conclusion:
Transscleral IOL fixation associated with Ahmed glaucoma drainage device implantation is a safe and effective surgical option for patients with late IOL dislocation and elevated IOP.
Characteristics of Patients With Congestive Heart Failure or Chronic Obstructive Pulmonary Disease Readmissions Within 30 Days Following an Acute Exacerbation
Authors: Castillo Austin , Edriss Hawa , Selvan Kavitha , Nugent Kenneth 
Published: June 2017

Background:
The Hospital Readmissions Reduction Program targets Medicare patients with congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD) and penalizes hospitals that have increased 30-day readmission rates for these patients. The main goals of this study were to determine the clinical explanations for readmissions within 30 days, to identify possible deficiencies in patient care, and to identify typical characteristics of patients who were readmitted to the hospital.

Methods:
The medical records department at University Medical Center in Lubbock, Texas, generated a list of patients with a primary discharge diagnosis of either acute exacerbation of CHF or an acute exacerbation of COPD who were readmitted within 30 days of discharge. Data collected from the electronic medical records included demographic information, clinical information, laboratory data, electrocardiographic information, echocardiographic results, and radiographic information for the index admission and readmission hospitalization. The indication for readmission was determined after review of all clinical data.

Results:
The final study cohorts included 58 admission-readmission events for acute exacerbations of CHF (47 patients) and 27 admission-readmission events for acute exacerbations of COPD (16 patients). Patients in both cohorts had significant comorbidity and frequent admissions during the 12 months prior to their index admissions. Patients with COPD had predominantly an emphysematous phenotype. Chest radiographs in patients with CHF showed cardiomegaly, pulmonary edema, and pleural effusions. Patients with CHF were discharged with suboptimal medication regimens. Referral to outpatient rehabilitation programs was low in both groups.

Conclusions:
Patients with acute exacerbations of COPD or CHF who require readmission within 30 days have complex comorbidity. They appear to have typical clinical profiles (emphysematous-type COPD patients and CHF patients with fluid overload), are frequently discharged with suboptimal medication regimens, and are not referred to outpatient rehabilitation. These patients had frequent hospitalizations prior to index hospitalizations. This information provides the basis for a focused review of patients admitted to the hospital to identify factors that might contribute to readmission.
Birds have swing: Multifractal analysis reveals expressive rhythm in birdsong
Authors: Roeske Tina , Kelty-Stephen Damian , Wallot Sebastian 
Published: June 2017

AbstractMusic is thought to engage its listeners by driving feelings of surprise, tension, and relief through a dynamic mixture of predictable and unpredictable patterns, a property summarized here as “expressiveness”. Birdsong shares with music the goal to attract and hold its listeners’ attention and might make use of similar strategies to achieve this goal. We here tested a songbird’srhythm, as represented by the amplitude envelope (containing information on note timing, duration, and intensity), for expressiveness. We used multifractal analysis which is designed to detect in a signal dynamic fluctuations between predictable and unpredictable states on multiple timescales (e.g. notes, subphrases, songs). Results show that the songs' amplitude envelope is strongly multifractal, indicating rhythm is patterned by fluctuations between predictable and unpredictable patterns. Moreover, comparing original songs with re-synthesized songs that lack all subtle deviations from the “standard” note envelopes, we find that deviations in note intensity and duration significantly contribute to the rhythm’s multifractality. This suggests that birds render their songs more expressive by subtly modifying note timing patterns, similar to musical operations likeaccelerandoorritardando. Our findings bear consequences for neuronal models of vocal sequence generation in birds, as they require non-local rules to generate rhythm.
Genetic risk for schizophrenia influences substance use in emerging adulthood: An event-level polygenic prediction model
Authors: Mallard Travis T. , Harden K. Paige , Fromme Kim 
Published: June 2017

AbstractBackgroundEmerging adulthood is a peak period of risk for alcohol and illicit drug use. Recent advances in psychiatric genetics suggest that the co-occurrence of substance use and psychopathology arises, in part, from a shared genetic etiology. We sought to extend this research by investigating the influence of genetic risk for schizophrenia on trajectories of four substance use behaviors as they occurred across emerging adulthood.MethodYoung adult participants of non-Hispanic European descent provided DNA samples and completed daily reports of substance use for one month per year across four years (N=30,085 observations of N=342 participants). Polygenic scores for schizophrenia were included in two-level hierarchical linear models designed to test associations between genetic risk for schizophrenia, participant age, and four substance use phenotypes.ResultsHere, we interpret results at p<.05 as suggestive and results at p<.005 as significant. Accordingly, our results suggest that polygenic scores for schizophrenia were positively associated with participants’ overall likelihood to engage in illicit drug use, but not alcohol-related substance use. Moreover, our results indicate that participants with a greater polygenic loading for schizophrenia experienced greater age-related increases in the likelihood of using substances across emerging adulthood.ConclusionsThe present study used a novel combination of polygenic prediction and intensive longitudinal methods to characterize the influence of genetic risk for schizophrenia on patterns of age-related change in substance use across emerging adulthood. Results suggest that genetic risk for schizophrenia exerts both broad and developmentally-specific influences on substance use behaviors in a non-clinical population of young adults.
The putative polyketide cyclase MSMEG_0129 fromMycobacterium smegmatis: purification, crystallization and X-ray crystallographic analysis
Authors: Zheng Shuping , Zhou Ying , Fleming Joy , Zhou Yafeng , Liu Wei , Bi Lijun 
Published: June 2017

Mycobacterium tuberculosisRv0164 has previously been identified as a human T-cell antigen that induces significant production of IFN-γ in human peripheral blood mononuclear cells.M. smegmatisMSMEG_0129 shares 59% sequence identity with Rv0164. Based on sequence alignment, both proteins are predicted to be members of the cyclase/dehydrase family, which is part of a large group of enzymes referred to as type II polyketide synthases (PKSs). In biosynthetic pathways mediated by type II PKSs, cyclases catalyze the conversion of linear poly-β-ketones to cyclized intermediates. To date, no mycobacterial type II PKSs have been reported. Here, the goal is to determine whether these proteins adopt similar folds to reported cyclase structures, and to this end MSMEG_0129 was cloned, expressed, purified and crystallized. An X-ray diffraction data set was collected to 1.95 Å resolution from a crystal belonging to space groupP62, with unit-cell parametersa= 109.76,b= 109.76,c= 56.5 Å, α = 90, β = 90, γ = 120°. Further crystallographic analysis should establish a basis for investigating the structure and function of this putative mycobacterial type II PKS enzyme.
Design of a bandwidth enhanced hybrid slot loop antenna for GSM/UWB standards
Authors: B. Partibane , M. Gulam Nabi Alsath , Rajakani Kalidoss 
Published: June 2017

Purpose
This paper aims to presents the bandwidth enhancement of a hybrid slot–loop antenna using a modified feed structure.

Design/methodology/approach
The conventional monopole feed of the hybrid slot–loop radiator is loaded with a flat microstrip patch to excite higher-order modes. The proposed antenna combines the resonant modes of the slot antenna, the loop antenna and the patch loading.

Findings
The antenna exhibits a dual-band response suitable for GSM 1800/1900 and ultrawideband (UWB) standards. The impedance bandwidth extends from 1.65 to 1.95 GHz (11.42 per cent) and 3 to 11.1 GHz (114.9 per cent). The proposed antenna has the smallest footprint with a peak gain of 5.07 dBi at 1.8 GHz and 4.97 dBi at 6 GHz. The prototype antenna is fabricated and the simulation results are validated using experimental measurements. The performance of the bandwidth-enhanced hybrid slot–loop antenna is compared with that of other slot antennas.

Originality/value
Thus, a hybrid slot–loop antenna with an enhanced bandwidth has been reported in this study. The conventional monopole feed of the antenna is replaced with a monopole ending with a microstrip patch load. The antenna covers the operating bands of GSM 1800/1900 and UWB. The proposed antenna has a smaller footprint compared with other wide-slot antennas reported in the literature.

Authors: Achour Meguellati , Binti Abdul Khalil Shahidra , Binti Ahmad Bahiyah , Mohd Nor Mohd Roslan , Zulkifli Bin Mohd Yusoff Mohd Yakub 
Published: June 2017

Purpose
This study aims to examine the relationship of work–family demands with employees’ well-being, and the role of management/supervisory support in this relationship. The following hypotheses were proposed: work–family demands would be negatively related to employees’ well-being; management/supervisory support would moderate the relationship of work–family demands with employees’ well-being.

Design/methodology/approach
The researchers used 250 working female academicians as respondents, working in the research universities in Kuala Lumpur, Malaysia. Their ages ranged from 30 to 60 years.

Findings
The findings of the present study proved that the work–family demands were negatively associated with employees’ well-being. Results also revealed that management and supervisory support strengthens the relationship between work–family demands and employees’ well-being. Thus, management and supervisory support plays an important role in balancing work demands and family roles and also in increasing working female academicians’ well-being.

Originality/value
In this study, management and supervisory support was found to be directly related to well-being, including life satisfaction, job satisfaction and family satisfaction. However, the direct relationship between management/supervisory support and well-being was positive and significant. This study also found that management/supervisor support reduced work–family conflict and work–family demands. Also, supervisory and management support was found to have a significant and positive relationship with well-being. Given these findings, supervisory and management support plays a very important role as a moderator of work–family demands and in developing and improving well-being in working women.
Customers’ Islamic ethical behavior: the case of Malaysian Islamic banks
Authors: Zakiah Farah , Al-Aidaros Al-Hasan 
Published: June 2017

Purpose
The purpose of this paper is to determine the framework of customers’ Islamic ethical behavior in Islamic banks in Malaysia.

Design/methodology/approach
This paper used a quantitative approach based on Maqasid Shariah (objectives of Islamic law) and by running exploratory factor analysis. A survey questionnaire was created. The data of 530 respondents were collected from the customers of Islamic banks located in Malaysia.

Findings
The findings revealed that the theoretical framework consists of four main constructs: Islamic ethical behavior, religious obligation, reputation and profit and investment, in which all constructs are complying with Maqasid Shariah and three (i.e. Islamic ethical behavior, religious obligation and reputation) consist of two components for each construct.

Research limitations/implications
There are two limitations that require further acknowledgements. First, the study population only focused on Islamic banks’ customers. Second, this research highlighted only Malaysia and Malaysian citizens.

Originality/value
The paper contributes to the literature on Islamic ethical behavior in Southeast Asian economy. Unlike other Islamic ethical studies where the writing is mainly theoretical in nature, this study used an empirical method to reveal what should constitute for the framework of customers’ Islamic ethical behavior which is based on Maqasid Shariah.
Under- vs over-investment: hotel firms’ value around acquisitions
Authors: Dogru Tarik 
Published: June 2017

PurposeThe purpose of this study is to analyze the extent to which under- and over-investment problems affect hotel firms’ value around the time when acquisitions are announced.Design/methodology/approachHotel firms are classified based on their financial constraints (under-investment), corporate governance mechanisms (over-investment) and organizational structures. Multivariate analyses are conducted utilizing the panel ordinary least squares regression to examine the effects of financial constraints, corporate governance mechanisms and organizational structures on acquisition returns.FindingsThe results show that financial constraints have a larger effect on the firm value compared to the effect of corporate governance. Also, acquisitions are viewed as over-investments in poorly governed, franchising and hotel-real estate investment trust (REIT) firms.Research limitations/implicationsThe analyses are limited to gains from acquisitions in the hotel industry. Therefore, future studies may examine the effects of capital expenditures and cash holdings on hotel firm value.Practical implicationsAcquisitions could help financially constrained firms reduce informational asymmetries. Firms could expand through franchising when they are financially constrained. However, franchising firms should take restrictive actions to control managers from making acquisitions. The hotel-REIT organizational form does not seem to cause under-investment problems, and it functions as an additional corporate governance mechanism.Originality/valueIn addition to the C-corporation organizational structure, hotel firms extensively adopt REIT and expand through franchising, which might affect under- and over-investment problems. Nonetheless, little is known about whether capital investments create or reduce value for hotel firms. This study helps to explain how financial constraints, corporate governance mechanisms and organizational structures affect hotel firms’ value.
Push and pull escape travel motivations of Emirati nationals to Australia
Authors: Michael Noela , Wien Charlotte , Reisinger Yvette 
Published: June 2017

Purpose
The purpose of this study is to examine the escape motivations of the emerging market and provide suggestions for Australia’s promotion. This study adopts the push and pull framework to identify travel motivations of Emirati nationals to Australia.

Design/methodology/approach
This study uses a series of focus groups and in-depth interviews to understand the escape motivations that encourage Emiratis to leave their home country and travel to Australia for a holiday.

Findings
The results indicate that Emiratis are motivated to travel to Australia by three escape factors: physical, interpersonal and fun. The internal motivations that encourage Emiratis to escape their home country are inseparable from Australia’s external attributes that attract the Emiratis to the country.

Originality/value
The study contributes to the theory of tourist motivation by supporting it in the culturally different Muslim/Arab context, which has not been explored before. The authors argue that it is not so much what Australia offers and what escape needs the Emiratis can fulfil in Australia, but rather that Australia serves the Emiratis well and meets their escape needs.

Authors: Ghadge Abhijeet , Fang Xie , Dani Samir , Antony Jiju 
Published: June 2017

Purpose
The purpose of this paper is to proactively analyse and mitigate the root causes of the product and security risks. The case study approach examines the effectiveness of the fuzzy logic approach for assessing the product and process-related failure modes within global supply chain context.

Design/methodology/approach
The case study of a Printed Circuit Board Company in China is used as a platform for conducting the research. Using data triangulation, the data are collected and analyzed through interviews, questionnaires, expert opinions and quantitative modelling for some interesting insights.

Findings
Fuzzy logic approach for failure mode and effect analysis (FMEA) provides a structured approach for understanding complex behaviour of failure modes and their associated risks for products and processes. Today’s managers should conduct robust risk assessment during the design stage to avoid product safety and security risks such as recalls.

Research limitations/implications
The research is based on the single case study and multiple cases from different industry sectors may provide some additional insights.

Originality/value
The study attempts to mitigate the root causes of product and processes using fuzzy approach to FMEA in supply chain network.

Students of humanities and social sciences and e-democracy
Authors: Petr Balog Kornelija , Badurina Boris 
Published: June 2017

Purpose
The purpose of this paper is to find out whether the students of the Faculty of Humanities and Social Sciences (FHSS) in Osijek, Croatia, interact online with any sort of e-democracy or e-government information.

Design/methodology/approach
This paper presents the findings of a pilot-study conducted among the undergraduate and graduate students of the FHSS in Osijek. The research was conducted in May 2015 on a sample of 246 students. The research was carried out by means of an online and paper survey and reached 59.91 per cent of the population of students enrolled in the first year of undergraduate and graduate studies.

Findings
Students in our sample spend a lot of time online. They are relatively active online when it comes to finding information connected with their academic responsibilities (e.g. 77.2 per cent of the students of the sample have gone online for finding information about exams, scholarships, etc.), but rarely engage in democratic processes within the academic community (only 11.8 per cent have contacted their student representative on the University Student Board). They are even less interested in democratic processes within the local community (8.1 per cent have contacted their local authority representatives regarding an administrative or communal matter).

Originality/value
This is the first research of FHSS students’ perceptions and views regarding their engagement and their information behavior regarding e-democracy and e-government processes and one of the very few such researches in Croatia.
