Heat and mass transfer analysis in natural convection flow of nanofluid over a vertical cone with chemical reaction
Authors: Reddy P. Sudarsana , Chamkha A. 
Published: February 2017

Purpose
In recent years, nanofluids are being widely used in many thermal systems because of their higher thermal conductivity and heat transfer rate. The higher thermal conductivity depends on many parameters such as size, shape and volume and the Brownian motion and thermophoresis of added nanoparticles. The purpose of this paper is to analyze the influence of the Brownian motion and thermophoresis on natural convection heat and mass transfer boundary layer flow of nanofluids over a vertical cone with radiation.

Design/methodology/approach
Using similarity variables, the non-linear partial differential equations, which represent momentum, energy and diffusion, are transformed into ordinary differential equations. The transformed conservation equations are solved numerically subject to the boundary conditions by using versatile, extensively validated, variational finite-element method.

Findings
The sway of significant parameters such as magnetic field (M), buoyancy ratio parameter (Nr), Brownian motion parameter (Nb), thermophoresis parameter (Nt), thermal radiation (R), Lewis number (Le) and chemical reaction parameter (Cr) on velocity, temperature and concentration evaluation in the boundary layer region is examined in detail. The results are compared with previously published work and are found to be in agreement. The velocity distributions are reduced, while temperature and concentration profiles elevate with a higher (M). With the improving values of (R), the velocity and temperature sketches improve, while concentration distributions are lowered in the boundary layer region. The temperature and concentration profiles are elevated in the boundary layer region for higher values of (Nt). With the increasing values of (Nb), temperature profiles are enhanced, whereas concentration profiles get depreciated in the flow region.

Social implications
In recent years, it has been found that magneto-nanofluids are significant in many areas of science and technology. It has applications in optical modulators, magnetooptical wavelength filters, tunable optical fiber filters and optical switches. Magnetic nanoparticles are especially useful in biomedicine, sink float separation, cancer therapy, etc. Specific biomedical applications involving nanofluids include hyperthermia, magnetic cell separation, drug delivery and contrast enhancement in magnetic resonance imaging.

Originality/value
To the best of the authors’ knowledge, no studies have assessed the impact of the two slip effects, namely, Brownian motion and thermophoresis, on the natural convection of electrically conducted heat and mass transfer to the nanofluid boundary layer flow over a vertical cone in the presence of radiation and chemical reaction; therefore, this problem has been addressed in this study. Comparison of the results of this study’s with those of previously published work was found to be in good agreement.

Authors: Owusu Godfred Matthew Yaw , Ossei Kwakye Teddy , Welbeck Edem Emerald , Ofori Charles Gyamfi 
Published: February 2017

Purpose
This study examines the multidimensionality of the environmental literacy concept among university business students in Ghana. The study also investigates the relationship between students’ interests in environmental issues and knowledge levels of environment and assesses how these two constructs influence students overall environmental behaviour and actions.

Design/methodology/approach
Using a total of 591 business students from the University of Ghana Business School, the study uses exploratory factor analysis to examine the multidimensionality of environmental literacy concept. A structural equation modelling-based approach was used to examine the relationship among the study constructs.

Findings
Based on the factor analysis results, the study documents that environmental literacy concept can be grouped under four distinct factors (general environmental factors; industry-related factors; environmental assessment factors; and accounting-related factors). The regression results indicate a direct and positive relationship between students’ interest in environmental issues and their environmental literacy level. Also, students’ interest and their knowledge levels of environmental issues were found to be good predictors of actual students’ involvement in activities that promote sustainable environment.

Research limitations/implications
The conclusions of the study are based on only data from one public university, which limits the generalizability of the findings.

Originality/value
The study is unique as it is the first empirical study to investigate environmental literacy levels in higher education in the Ghanaian setting.
Liquidity risk management: conventional versus Islamic banking system in Egypt
Authors: Abdel Megeid Nevine Sobhy 
Published: February 2017

PurposeThis research aims to analyze and compare the effectiveness of liquidity risk management of Islamic and conventional banking in Egypt to ascertain which of the two banking systems are performing better.Design/methodology/approachA sample of six conventional banks (CBs) and two Islamic banks (IBs) in Egypt was selected. Using the liquidity ratios, the investigation involves analyzing the financial statements for the period of 2004-2011. The data were obtained from Bank scope database.FindingsThe research found that in Egypt, CBs perform better in terms of liquidity risk management than IBs. The liquidity risk management significant differences between IBs and CBs could be attributed more cash availability to CBs than to IBs, in addition, Egyptian Central Bank regulations on capital and liquidity requirements for IBs disconcert IBs’ performance.Practical implicationsThis research facilitates the bankers, academician, scholars and bankers to have an alluded picture about Egyptian banking developments in liquidity risk management. The results can be used by bankers’ policy decision-makers to improve and enhance their consideration for liquidity risk management.Originality/valueThis research covers a period and a country that compares CBs’ and IBs’ liquidity risk management. Its value is attributed to the increasing differentiation between CBs and IBs.
Financial development, Islamic finance and economic growth: evidence of the UAE
Authors: Zarrouk Hajer , El Ghak Teheni , Abu Al Haija Elias 
Published: February 2017

Purpose
Does Islamic finance affect economic growth? The empirical literature in this area seems to be in early stages and the results are often mixed and inconclusive. This paper aims to examine the causality between financial development in general, Islamic finance in particular and real economic growth in the United Arab Emirates (UAE).

Design/methodology/approach
Using time series data from 1990 to 2012, a bivariate vector autoregressive model was used to document the financial development-Islamic finance-growth causal nexus and to forecast growth under various scenarios. A composite indicator, as a proxy for financial development, was determined using a non-parametric approach: data envelopment analysis.

Findings
The direction of causality runs from financial development to economic growth and the reverse causality does not drive this relationship; however, the real gross domestic product (GDP) causes Islamic financial development with no reverse effect. Furthermore, the forecasting results indicate that the past relation has been a proxy for the future where financial development leads to better progress in real economic activity. This will likely continue to stimulate the development of Islamic finance.

Research limitations/implications
Because the financial markets in the UAE were established in 2000, this study ignored Islamic bonds and equity product. The value of the Sukuk listed on Dubai’s exchanges is around US$36.75bn (Thomson Reuters, 2015), reinforcing Dubai’s position as an international center for Sukuk activity. Among the most important tools of the Islamic financial sector, Sukuk deserves a closer empirical study. This can set the agenda for future work.

Practical implications
The financial sector appears to be one of the main drivers of real economic activity. However, more effort in the area of Islamic finance is needed to promote Shari’ah-compliant economic activities and thus better contribute toward making Dubai-UAE the capital of the Islamic economy.

Originality/value
A new indicator was used to evaluate the financial strength of the UAE and analyze its effect on economic development. In addition, as one of UAE’ emirates, Dubai declared its vision in 2013 to become the “capital of the Islamic economy”, this study analyzed the finance, Islamic finance and growth relations over the period 2013-2022.
Online search-based advertising strategy for e-Business platform with the consideration of consumer search cost
Authors: Ma Buqing , Xu Xiaoyan , Sun Yanhong , Bian Yiwen 
Published: February 2017

Purpose
Consumers are increasingly using search-based advertising in e-Business platforms to seek their desirable products. Platforms will choose a centralized advertising mechanism (CAM) or decentralized advertising mechanism (DAM) to offer a search advertising service to lower consumer search cost, as represented by using search time length. It is important for the platform to decide how to choose advertising mechanisms, and how to determine the optimal advertising price and search time length. To address these issues, this study aims to develop a theoretical approach under each mechanism to examine the platform’s optimal search-based advertising strategy by considering search cost.

Design/methodology/approach
In this study, two models are developed to examine the optimal search-based advertising strategy by considering consumer search cost (i.e. search time length). By comparing the platform’s profits under two models, the optimal advertising strategy, search time length and price are explored.

Findings
It is found that when the seller’s reserve benefit is sufficiently large, the platform benefits from choosing the DAM; otherwise, the CAM is a better choice. The advertising service is usually offered with a shorter search time length accompanied by a higher charge, and a longer search time length accompanied by a lower charge. Specifically, when the seller’s reserve benefit is substantially high, a DAM that benefits both the platform and seller is a better choice. This can explain why many platforms offer advertising services with a DAM.

Originality/value
This paper is the first theoretical study on addressing the search-based advertising strategy, especially the choice of advertising mechanisms, in the online advertising context. It is also the first piece of analytical research that considers the effect of consumer search cost on product demand, and then examines the optimal advertising price and search cost (i.e. search time length) for online platforms.
ANTi-History, relationalism and the historic turn in management and organization studies
Authors: Durepos Gabrielle , Mills Albert J. 
Published: February 2017

Purpose
This paper develops and provides insights on how researchers can use ANTi-History with a focus on one of its constitutive facets, relationalism. The purpose of this paper is to, first, develop a central facet of ANTi-History called relationalism and to outline how researchers interested in doing organizational history can use ANTi-History insights to undertake relational histories.

Design/methodology/approach
The authors propose four phases of the historic turn literature and situate ANTi-History and relationalism as an outcome of the fourth phase. The facet of relationalism is then explained and explored through five types of relations that the authors suggest act as sites of oscillation, where the past becomes (an immutable) history.

Findings
A central implication of the paper involves disrupting conceptualizations of the past and history as fixed. Instead, history is explained as a relational outcome of its constitutive social and political relationships.

Originality/value
The paper theoretically develops ANTi-History and relationalism while providing practical implications and tools for researchers to use it. Researchers are introduced to the notion of the site of oscillation. They are encouraged to focus their attention on five sites of oscillation: past-history, actor-network, human-nonhuman, researcher-traces of the past, and historical inscription-reading formation. These sites of oscillation are places where politics is at play and history is shaped or transformed.

Published: February 2017

Purpose
The purpose of this paper is to review the literature on female faculty and administrators working in higher education, past and present.

Design/methodology/approach
Materials were selected based on scholarly impact and reputation of the author. Selections were then examined to assure varied perspectives and wide period coverage.

Findings
Throughout the past century, women have made tremendous strides in the pursuit of equity in the academic working environment. However, statistics and personal experiences indicate that much progress is still needed.

Research limitations/implications
This bibliography is limited to literature on working female faculty and administrators in the USA. It is intended to provide a broad overview of their past and present working conditions. Materials cover the Colonial period though the present. As such, a brief selection of materials available are included. Although there are much fewer resources that include the women of color experience, whenever possible materials are included. For the purpose of this review, the female student demographic is omitted. As there is a plethora of materials on this subject, it should be examined in a separate bibliography.

Originality/value
This bibliography provides students and scholars a brief introduction to research women in higher education which encompasses diverse voices, a wide historical range and contemporary materials.
Adjuvant rituximab treatment for pemphigus: A retrospective study of 45 patients at a single center with long‐term follow up
Authors: Kim Tae Hyung , Choi Yuri , Lee Sang Eun , Lim Jung Min , Kim Soo‐Chan 
Published: February 2017

AbstractTo evaluate the long‐term outcomes of rituximab in the treatment of pemphigus and the influence of disease duration and different dose of rituximab on the clinical response, 45 patients with refractory pemphigus treated with at least one cycle of two infusions of rituximab (375 mg/m2 per infusion weekly) were retrospectively studied. All patients were followed up for more than 2 years. All patients achieved complete or partial remission within 8 months of the first cycle. Thirty‐four (76%) patients relapsed at a median of 17 months. All patients who received additional cycles after relapse achieved new remissions. Early use of rituximab within 1 year of disease duration and high‐dose therapy induced better outcomes, although the results in early use were not statistically significant. Acute respiratory distress syndrome occurred in one patient. Rituximab is effective in treating pemphigus, but relapses are frequent during long‐term follow up, and additional cycles are beneficial in relapsed cases. Early and high‐dose rituximab therapy may be more effective.
Democracy in Britain: Retrospect and Prospect
Authors: Wright Tony 
Published: February 2017

AbstractThe EU referendum has raised questions about the nature of democracy, which is not just majority rule. It is wrong to claim that direct democracy has now replaced representative democracy, as Parliament is required to answer all the questions that the referendum did not. The conduct of the referendum reflected the worst aspects of Britain's political culture of sterile adversarialism. Both left and right have shared assumptions about governing that have made it difficult to develop a culture of democratic citizenship. The political system still reflects its pre‐democratic origins (as in the survival of a House of Lords and the obsession with titles) and the role of money in politics represents a form of corruption. Institutional reforms depend for their success on the nurturing of a democratic culture, which is a task for many hands.
Quantitative Differentiation of Bloodstain Patterns Resulting from Gunshot and Blunt Force Impacts
Authors: Siu Sonya , Pender Jennifer , Springer Faye , Tulleners Frederic , Ristenpart William 
Published: February 2017

AbstractBloodstain pattern analysis (BPA) provides significant evidentiary value in crime scene interpretation and reconstruction. In this work, we develop a quantitative methodology using digital image analysis techniques to differentiate impact bloodstain patterns. The bloodstain patterns were digitally imaged and analyzed using image analysis algorithms. Our analysis of 72 unique bloodstain patterns, comprising more than 490,000 individual droplet stains, indicates that the mean drop size in a gunshot spatter pattern is at most 30% smaller than the mean drop stain size in blunt instrument patterns. In contrast, we demonstrate that the spatial distribution of the droplet stains—their density as a function of position in the pattern—significantly differs between gunshot and blunt instrument patterns, with densities as much as 400% larger for gunshot impacts. Thus, quantitative metrics involving the spatial distribution of droplet stains within a bloodstain pattern can be useful for objective differentiation between blunt instrument and gunshot bloodstain patterns.
Identification and laboratory behavioral test of the alarm pheromone of Acanthocoris sordidus Thunberg (Hemiptera: Coreidae)
Authors: Shin Eunsik , Kim Junheon , Park Chung Gyoo 
Published: February 2017

AbstractThe winter cherry bug, Acanthocoris sordidus Thunberg (Hemiptera: Coreidae), widely spread in South Korea, Japan and Taiwan, is becoming an economic pest in these regions. Its elevated pest status in pepper plant, Capsicum annuum, is a trigger for eco‐friendly management tactics. In order to use its pheromone for pest management, the cuticular components of adult A. sordidus were identified and a behavioral bioassay on the functions of the components was conducted. From the whole‐body extracts of male and female A. sordidus, 13 compounds (hexanal, 1‐hexanol, 2‐hexanol, 3‐hexanol, hexanoic acid, hexyl acetate, heptyl acetate, octyl acetate, tetradecane, 2‐butyl‐2‐octenal, hexyl hexanoate and (2α,4α,6β)‐2,4,6‐tripentyl‐1,3,5‐trioxane (hexanal trimer, cis‐ and trans‐forms) were identified. In addition to these, two unidentified compounds, a male‐specific and a male‐rich compound, were also found. Hexanal provoked clear escaping behavior. 1‐Hexanol, hexyl acetate and hexanoic acid evoked weaker behavior than hexanal. We concluded that hexanal worked as an alarm pheromone and could be used as a pushing signal for a control program for A. sordidus.

Published: February 2017

AbstractIn this study, the opportunity to enhance the insecticidal activity of Rosmarinus officinalis essential oil was studied for effective management of the red flour beetle, Tribolium castaneum, as a stored product pest beetle. Nanoprecipitation method was used to prepare rosemary oil‐loaded nanocapsules. Bioassays were conducted at 27–30°C temperature and 70–75 % relative humidity in the dark. Fumigant toxicity of the non‐formulated oil and nanocapsules of R. officinalis were investigated at 13.20, 15.92, 19.12, 23.04, and 27.76 μL/L air after 24 and 72 h exposure and the contact toxicity of the non‐formulated oil and nanocapsules were investigated at 4.28, 3.55, 2.95, 2.45 and 2.36 μL/cm2 after 24 h exposure. The major constituents of the essential oil of rosemary were α‐Pinene, 1,8‐cineol, camphor, and cis‐verbenone. Nanocapsules presented an average size (145 ± 15 nm) (± standard error [SE]) with a polydispersity index below 0.3, a negative zeta potential (−11.0 ± 0.5 mV), and a high encapsulation efficiency (78.20 ± 0.93 %). Scanning electron microscope photomicrograph of rosemary oil‐loaded nanocapsules showed the presence of spherical nanocapsules with regular and homogeneous surfaces. In fumigant and contact toxicity, there were significant differences between non‐formulated and rosemary oil‐loaded nanocapsules in all the concentrations and times. The results suggested that nanoencapsulated essential oils from R. officinalis can be used for effective control in T. castaneum. When this technique is used, it can produce pesticides that have controlled‐release properties and reduce the concentration of the applied doses and number of applications.
Full‐field digital mammography: Is the apparent increased detection of microcalcification leading to over‐investigation and over‐diagnosis?
Authors: Porter Alan J , Evans Elizabeth B , Erzetich Lisa M 
Published: February 2017

AbstractIntroductionModern full‐field digital mammography (FFDM) appears to have increased the detection of breast microcalcification. This retrospective study aimed to assess whether this is associated with over‐investigation and possible over‐diagnosis of breast pathology of lesser significance.MethodsThree 2‐year periods were studied, in which different mammographic technologies were used exclusively viz., classical screen‐film mammography (SFM) in 2003–04, computed radiography (CR) in 2009–10 and FFDM in 2012–13. The study was limited to women in whom biopsy was done for indeterminate, suspicious or malignant (ISM) calcification as the only mammographic abnormality.ResultsBetween the first and the third time periods, the use of core biopsies and vacuum‐assisted biopsies (VABs) for ‘ISM calcification only’ increased from 0. 6% to 1.4% of all mammograms, and biopsies with malignant results increased from 0.18% to 0.33% of all mammograms. VAB became the preferred technique for biopsy over the study period. The proportion of cores and VABs with a malignant result did not change significantly over the three time periods (24–28%), nor did the proportion of invasive cancers, ductal carcinoma in situ (DCIS) (60–63%) or atypia on subsequent excision. The proportion of DCIS which was of high grade was greatest in the FFDM era (69%). Less than 9% of DCIS were of low grade in all three time periods.ConclusionsDespite increased numbers of biopsies being performed, there was no increase in findings of breast pathology of lesser significance. Improved technology (FFDM and VAB) allows immediate biopsy of small clusters of indeterminate microcalcification, rather than using mammographic surveillance, and this study found no evidence that this has been associated with over‐investigation or over‐diagnosis.
