Why wait? Impact of waiting lines on self-service technology use
Authors: Kokkinou Alinda , Cranage David A. 
Published: July 2015

Purpose
– The purpose of the present study is to examine the effect of waiting lines on customers’ decisions between using a self-service alternative and using a service employee. As self-service technologies are expensive and time-consuming to design and implement, service providers need to understand what drives customers to use them. Service operators have the most control over waiting lines and flexibility in expanding capacity, either by adding service employees or by adding self-service kiosks.

Design/methodology/approach
– The study used online scenario-based surveys following a 4 (number of customers waiting for the self-service technology) × 4 (number of customers waiting for the service employee) design. A binary dependent variable was used to record participants’ choice of service delivery alternative.

Findings
– Using logistic regression, the authors found that customers are increasingly motivated to use self-service technology as the waiting line for the service employee grows longer. This effect is influenced by perceived usefulness, anticipated quality of the self-service technology, need for interaction and technology anxiety.

Research limitations/implications
– This study should be replicated in a real-world setting where actual behavior, and not only intention, can be measured.

Practical implications
– The study provides guidance on how service providers can design their service to take advantage of the motivating effect of waiting lines on usage of self-service technology.

Originality/value
– The present study is the first to combine a scenario-based experiment with a binary dependent variable to isolate the impact of waiting lines on the choice between using a self-service technology and using a service employee. The use of the binary dependent variable overcomes the ambiguity of extrapolating from a continuous measure of intention to draw conclusions about behavior, a binary variable.

Published: July 2015

Purpose– The purpose of this paper is to compare the different preferences between property practitioners and residential consumers on housing prices in the Jakarta Metropolitan Region.Design/methodology/approach– The Jakarta Metropolitan Region as the largest metropolitan city in Indonesia was selected as the main sample city for this study. This study comprises 134 respondents from property practitioners and 277 respondents from residential consumers. Data were collected from all regions in Jakarta Metropolitan Region and their respective satellite cities. Descriptive analysis, the correlation study, Wilcoxont-test and principal component analysis were used to compare the findings between each group’s preferences on housing attributes.Findings– The results of this research provide an analysis on the different decisive attributes for each group, disparities on the correlation between attributes in housing consumers and property practitioners and disagreements among each group on the attribute preferences influencing housing prices in the Jakarta Metropolitan Region.Research limitations/implications– In conclusion, the study provides valid and dependable evidence on different consumers and property practitioners attribute preferences for housing products in the Jakarta Metropolitan Region.Originality/value– This research is the first to compare the attribute preferences for housing products between housing consumers and property practitioners in Indonesia. In addition, this study is one of the first to reaffirm preference attributes influencing housing product prices in Indonesia.
Housing supply and its relationships with land supply
Authors: Gu Guowei , Michael Lynne , Cheng Yapeng 
Published: July 2015

Purpose– This paper aims to explore the determinants of housing supply and the relationships between land supply and housing supply in terms of quantity and time in Shanghai, China.Design/methodology/approach– Official statistical and property registration data[] from Shanghai are used to carry out multiple linear regression analysis.Findings– The authors find that land supply affects housing supply with a three-year time lag. Both construction cost and housing price impact supply with a one-year time delay. The construction cost elasticities range from 0.74 to 1.51, while housing price elasticity is 2. The authors also find that plot ratio may play more important role in the developer’s first housing sale than either plot area or sales price. An average time period from obtaining the land for residential development until marketing the product is established at 36.8 months.Research limitations/implications– Only ordinary least squares method is applied in this analysis and the property portal on which this research relies is still at an early stage.Originality/value– This research contributes to a wider understanding of issues surrounding housing supply in the local markets within China and provides the foundation for local government to better manage supply.
Estimation and application of a complete demand system for the United Arab Emirates
Authors: Azzam Azzeddine , Rettab Belaid 
Published: July 2015

Purpose– The purpose of this paper is to estimate a complete demand system for the United Arab Emirates (UAE) and use the estimates to evaluate the welfare impact of price inflation. Eight expenditure groups are considered: food, clothing, housing, furniture, transportation, medical care, recreation, and miscellaneous.Design/methodology/approach– Household survey data are used to estimate the elasticities separately for Emiratis and expatriates by income quintile using seemingly unrelated regression within a Linear Expenditure System that accounts for demographic variables.Findings– Welfare loss is inversely related to income quintile and is lower for Emirati households. Transportation, housing, and food are the sources of the bulk of the welfare loss. The shares of the three consumption groups, combined with their respective inelastic demands, explain why they figure prominently as the leading sources of welfare loss when their prices rise.Originality/value– First ever demand system estimated for the UAE. Welfare loss estimates provide some rational basis on which examination may be made of existing UAE policies that effect commodity prices, like price controls, and policies currently being discussed, like commodity taxation, and their distributional effects.
Using downside risk in evaluating the performance of Malaysian mutual funds
Authors: Tavakoli Baghdadabad Mohammad Reza , Fooladi Masood 
Published: July 2015

Purpose
– The purpose of this paper is to provide the modified measures of risk-adjusted performance evaluation of Malaysian mutual funds using the downside risk concepts, and promote the ability of managers and investors in making logical decisions under the market asymmetry condition.

Design/methodology/approach
– This study focusses on the performance evaluation of Malaysian mutual funds using eight modified measures of Sharpe, Treynor, M2, Jensen’s α, information ratio (IR), MSR, SPI, and leverage factor. These modified measures use the downside systematic risk and semi-standard deviation instead of systematic risk and conventional standard deviation, respectively, to evaluate the performance of Malaysian mutual funds over the period 2000-2011.

Findings
– The results indicate that the conventional measures of performance evaluation do not have a crucial influence on the relative evaluation of mutual funds. Three modified measures of Sharpe, Treynor, and M2 have a high correlation with the conventional Sharpe measure and can be used instead of the conventional Sharpe measure. Since, two modified measures of Treynor and M2 display a high rank correlation coefficient with the conventional Treynor measure, they can be replaced with this traditional measure. In addition, two modified IR and MSR measures along with the modified SPI and conventional SPI show very high rank correlation coefficients in relation to each other. The results also document a modified leverage factor less than one for all funds. It can be concluded that the strategy of un-levering the investor’s holding must be followed.

Practical implications
– The empirical evidence of this study can be utilized as inputs in the process of decision-making by different types of investors who are interested in participating especially in Malaysian stock market and generally in global stock market under the market asymmetry condition.

Originality/value
– The contribution of this study is to modify five measures of M2, IR, MSR, FPI, and leverage factor in the downside risk framework which is a work on a rather under-researched area.
Legal system uncertainty and FDI attraction in Southeast Asia
Authors: White III George O. , Chizema Amon , Canabal Anne , Perry Mark J. 
Published: July 2015

Purpose– The purpose of this paper is to draw from organizational ecology and institutional theory, the authors suggest that there will be a curvilinear relationship between legal system uncertainty and foreign direct investment (FDI) attraction in Southeast Asia. The authors extend theory by arguing that this is because uncertainty will provide opportunities for FDI that seek this form of operating environment, leveraging legal system uncertainty as a basis for competitive advantage.Design/methodology/approach– The authors test and find support for the hypotheses using FDI data from nine Southeast Asian countries for the years 1995-2005.Findings– In this paper, the authors hypothesize and find that the relationship between legal system uncertainty and FDI attraction is curvilinear in nature, such that FDI attraction decreases with legal system uncertainty down to an inflection point, but then increases beyond this point; and that the relationship between legal system uncertainty and FDI attraction is moderated by government intervention in the host country economy, such that the strength of this relationship is greater when government intervention is high rather than when it is low. Implications of the findings and suggestions for future inquiry are presented.Originality/value– Conventional wisdom suggests that legal system uncertainty will negatively affect FDI attraction. However, to date, research on the effects of legal system uncertainty on FDI attraction in emerging markets has received very little attention. The aim of this research study is to shed new light on how, under certain conditions, legal system uncertainty will attract FDI in Southeast Asia.
Corporate diversification and firm value: evidence from emerging markets
Authors: Akben Selçuk Elif 
Published: July 2015

Purpose
– The purpose of this paper is to investigate the impact of corporate diversification on firm value in a sample of nine emerging markets including Brazil, Chile, Indonesia, Malaysia, Philippines, Poland, South Africa, Thailand, and Turkey. For the purpose of this study, a company is classified as diversified when it is operating in two or more lines of business defined by the two-digit SIC codes.

Design/methodology/approach
– Employing panel data from 1,568 companies for the period 2005-2010, this paper estimates both a fixed effects model and a dynamic generalized method of moments model. Data are collected both at company level and segment level within each firm.

Findings
– Overall, analysis results suggest that, for the period from 2005 to 2010, diversified firms in emerging markets are valued more compared to single-segment firms operating in similar industries, providing support for diversification premium.

Originality/value
– The effect of diversification on company value in emerging markets is an important managerial and public policy concern. Although the literature on developed country diversified firms is rich, only a few studies have examined diversification-value relationship in the context of developing countries. Furthermore, most previous research on the value effects of corporate diversification in emerging markets has taken the form of case studies within countries and concentrated on the 1990s. This paper tries to fill these gaps by using a larger sample and more recent data and methodology.
Relationship and networking strategy tools: characterizing the IMP toolbox
Authors: Cheng Caroline , Holmen Elsebeth 
Published: July 2015

Purpose
– The purpose of this paper is to systematically review the relationship and networking strategy tools in the IMP literature. It proposes six dimensions for characterizing such tools: approach to tool development, level (and layer) of analysis, perspective of interaction, activities of network strategizing, external or internal orientation and use for “strategizing on” vs “strategizing in” relationships and networks.

Design/methodology/approach
– The paper uses a manual qualitative content analysis approach and an inductive approach, well suited for extracting relationship and networking strategy tools due to their implicit and dispersed nature.

Findings
– The paper presents an IMP toolbox comprising a wide variety of relationship and networking strategy tools emphasizing interconnectedness, interdependence and limited managerial autonomy, as well as an analysis of how identified tools are positioned along each of the six proposed dimensions.

Research limitations/implications
– This paper contributes a conceptual framework with a vocabulary to content analyze and discuss relationship and networking strategy tools in IMP research.

Practical implications
– The IMP toolbox may be a useful point of departure for managers who feel a need for developing and using a mix of tools for strategizing in business relationships and networks.

Originality/value
– The paper instills a strategy tool lens in the IMP literature and foregrounds strategizing concepts and techniques that were previously difficult to attend to for both researchers and practitioners.
Multiple strategies for drought survival among woody plant species
Authors: Pivovaroff Alexandria L. , Pasquini Sarah C. , De Guzman Mark E. , Alstad Karrin P. , Stemke Jenessa S. , Santiago Louis S. 
Published: July 2015

SummaryDrought‐induced mortality and regional dieback of woody vegetation are reported from numerous locations around the world. Yet within any one site, predicting which species are most likely to survive global change‐type drought is a challenge.We studied the diversity of drought survival traits of a community of 15 woody plant species in a desert‐chaparral ecotone. The vegetation was a mix of chaparral and desert shrubs, as well as endemic species that only occur along this margin. This vegetation boundary has large potential for drought‐induced mortality because nearly all species are at the edge of their range.Drought survival traits studied were vulnerability to drought‐induced xylem cavitation, sapwood capacitance, deciduousness, photosynthetic stems, deep roots, photosynthetic responses to leaf water potential and hydraulic architecture. Drought survival strategies were evaluated as combinations of traits that could be effective in dealing with drought.The large variation in seasonal predawn water potential of leaves and stem xylem ranged from −6·82 to −0·29MPa and −6·92 to −0·27MPa, respectively. The water potential at which photosynthesis ceases ranged from −9·42 to −3·44MPa. Architecture was a determinant of hydraulic traits, with species supporting large leaf area per sapwood area exhibiting high rates of water transport, but also xylem that is vulnerable to drought‐induced cavitation. Species with more negative midday leaf water potential during the growing season also showed access to deeper water sources based on hydrogen isotope analysis.Drought survival mechanisms comprised of drought deciduousness, photosynthetic stems, tolerance of low minimum seasonal tissue water potential and vulnerability to drought‐induced xylem cavitation thus varied orthogonally among species, and promote a diverse array of drought survival strategies in an arid ecosystem of considerable floristic complexity.
Male butterflies use an anti‐aphrodisiac pheromone to tailor ejaculates
Authors: Larsdotter‐Mellström Helena , Eriksson Kerstin , Janz Niklas , Nylin Sören , Carlsson Mikael A. 
Published: July 2015

Summary

When females mate with multiple partners, the risk of sperm competition depends on female mating history. To maximize fitness, males should adjust their mating investment according to this risk. In polyandrous butterflies, males transfer a large, nutritious ejaculate at mating. Larger ejaculates delay female remating and confer an advantage in sperm competition.

We test whether male ejaculate size in the butterfly Pieris napi (Lepidoptera) varies with female mating history and thus sperm competition, and whether males assess sperm competition using the male‐transferred anti‐aphrodisiac methyl salicylate (MeS) as a cue.

Both sexes responded physiologically to MeS in a dose‐dependent manner. Males, however, were more sensitive to MeS than females.

Ejaculates transferred by males mating with previously mated females were on average 26% larger than ejaculates transferred by males mating with virgin females, which conforms to sperm competition theory and indicates that males tailored their reproductive investment in response to sperm competition. Furthermore, ejaculates transferred by males mating with virgin females with artificially added MeS were also 26% larger than ejaculates transferred to control virgin females.

Male‐transferred anti‐aphrodisiac pheromone not only functions as a male deterrent, but also carries information on female mating history and thus allows males to assess sperm competition.

Published: July 2015

SummaryPosture changes may differ between types of hypertensive disease. The aim is to evaluate the orthostatic response of impedance cardiography (ICG) measurements in uncomplicated and hypertensive pregnancies. Measurements were performed in supine and standing position in 202 women: 41 uncomplicated pregnancies (UP), 59 gestational hypertension (GH), 35 early‐onset (EPE, < 34 weeks) and 67 late‐onset (LPE, ≥ 34 weeks) preeclampsia were assessed. Measurements were recorded of heart rate, blood pressure, aortic flow parameters, cardiac output, pre‐ejection period and left ventricular ejection time. Overall, orthostatic shifts were different between all groups (P < 0.001). UP was different from the hypertensive complicated gestations in the orthostatic change of the aortic acceleration. In contrast to patients with preeclampsia, those with GH had an increased blood pressure and Heather index, and stable pre‐ejection period after posture change. EPE differed from LPE by change in blood pressure and aortic flow parameters. In addition to static ICG‐measurements, orthostatic shifts improved group characterization from 57.4% to 65.8%. The orthostatic response is altered in hypertensive pregnancies. ICG measurements in the upright as well as during an orthostatic test might have the potential to improve the discriminative yield between hypertensive diseases in pregnancy.
Canavanine increases glucose uptake in C2C12 cells through the activation of imidazoline I‐2B receptors
Authors: Chao Pin‐Chun , Chang Chin‐Hong , Niu Ho‐Shan , Huang Gin‐Chi , Chen Li‐Jen , Cheng Juei‐Tang 
Published: July 2015

SummaryCanavanine is a guanidinium derivative that contains the basic structure of the ligand(s) of imidazoline receptor (I‐R). Canavanine has been reported to activate the imidazoline I‐3 receptor (I‐3R) both in vivo and in vitro. Additionally, the activation of the imidazoline I‐2B receptor (I‐2BR) by guanidinium derivatives may increase glucose uptake. Therefore, the effect of canavanine on the I‐2BR was investigated in the present study. Glucose uptake into cultured C2C12 cells was determined using the radio‐ligated tracer 2‐[14C]‐deoxy‐glucose. The changes in 5′ AMP‐activated protein kinase (AMPK) expression were also identified using Western blotting analysis. The canavanine‐induced glucose uptake was inhibited in a dose‐dependent manner by BU224 (0.01–1 μmol/L), which is a specific I‐2BR antagonist, in the C2C12 cells. Additionally, the canavanine‐stimulated AMPK phosphorylation and glucose transporter (GLUT4) expression were also sensitive to BU224 inhibition in the C2C12 cells. Moreover, both canavanine‐stimulated glucose uptake and AMPK phosphorylation were attenuated by high concentrations of amiloride (1–2 μmol/L), which is another established I‐2BR inhibitor, in a dose‐dependent manner in C2C12 cells. Additionally, compound C abolished the canavanine‐induced glucose uptake and AMPK phosphorylation at a concentration (0.1 μmol/L) sufficient to inhibit AMPK. In conclusion, these data demonstrated that canavanine has an ability to activate I‐2BR through the AMPK pathway to increase glucose uptake, which indicates I‐2BR as a new target for diabetic therapy.
Who Will Feed China in the 21st Century? Income Growth and Food Demand and Supply in China
Authors: Fukase Emiko , Martin Will 
Published: July 2015

AbstractThis study uses resource‐based measures to explore the evolution of China's demand and supply for food. China's dietary shift from plant to animal‐based foods, induced by its income growth, is likely to impose considerable pressure on agricultural resources. China's demand for food on this measure appears consistent with global trends, while China is an out‐performer on the supply side, producing much more food than its income level and land endowment would predict. China's current per capita income is in a range where consumption growth is high and in excess of production growth, but the gap between supply and demand is likely to diminish as population and per capita consumption growth decelerate. Continuing agricultural productivity growth and sustainable resource management will be important influences on the growth of China's future net import demand for food.
Constructing Water Shortages on a Huge River: The Case of Shanghai

AbstractShanghai is located on the world's third largest river (by volume). Yet it faces the risk of shortages of drinking water. Many decisions and environmental characteristics have contributed to this threat. First, Shanghai has become dependent on water brought into the municipality by rivers. Second, it has become increasingly reliant on water from the Changjiang (Yangzi River), principally in order to control the levels of pollution in the water that enters its treatment plants. Third, for reasons associated with inter‐provincial administrative arrangements, the city's water intakes are located within the municipality, within the estuary zone and subject to tidal intrusions of salt water. Fourth, at high tide and when the Changjiang's discharge is low, salt intrudes far into the estuary, beyond the current water intakes. If sea levels rise, these intrusions will become more pronounced. Fifth, large‐scale central government infrastructure projects (such as dams and the South‐North Transfer) are altering the hydrological characteristics of the river. Such projects raise the probability of salt water intrusions into the water intake zone. The Shanghai and central governments have thus made a series of decisions that, taken together, have led the municipality to rely on a source of drinking water that is increasingly unreliable and subject to the risk of shortages due to salt water intrusions. Why these decisions have been made – independently – is an important problem for those who would understand the provision of water for cities and the practical efficacy of Chinese governance systems.
