Selling Off-Grid Light To Liquidity Constrained Consumers, Bhavani Shanker Uppari, Ioana Popescu, Serguei Netessine

Research Collection Lee Kong Chian School Of Business

Problem definition: A large proportion of the world’s population has no access to electricity and so relies on noxious kerosene for their lighting needs. Solar-based solutions require a large up-front investment and are often unaffordable in this market owing to consumers’ tight liquidity constraints. As an alternative, there are business models relying on rechargeable light bulbs that are sold at a subsidized price (which renders them affordable) and require regular micropayments for recharges (which eases liquidity constraints). These bulbs provide a cheaper and healthier light source than kerosene, yet their adoption is lower than expected, and some consumers continue …

Effects Of Ions-Releasing Restorative Materials On The Dentine Bonding Longevity Of Modern Universal Adhesives After Load-Cycle And Prolonged Artificial Saliva Aging, S Sauro, I Makeeva, V Faus-Matoses, F Foschi, M Giovarruscio, Pires P Maciel, Moura M Martins, Neves A Almeida, V Faus-Llácer

Peninsula Dental School

This study aimed at evaluating the microtensile bond strength (MTBS) and fractographic features of dentine-bonded specimens created using universal adhesives applied in etch-and-rinse (ER) or self-etching (SE) mode in combination with modern ion-releasing resin-modified glass-ionomer cement (RMGIC)-based materials after load cycling and artificial saliva aging. Two universal adhesives (FTB: Futurabond M+, VOCO, Germany; SCU: Scotchbond Universal, 3M Oral Care, USA) were used. Composite build-ups were made with conventional nano-filled composite (AURA, SDI, Australia), conventional resin-modified glass ionomer cement (Ionolux VOCO, Germany), or a (RMGIC)-based composite (ACTIVA, Pulpdent, USA). The specimens were divided in three groups and immersed in deionized water …

The Role Of Inspiring Role Models In Enhancing Entrepreneurial Intention, W Nowinski, My Haddoud

Plymouth Business School

Although current research highlights the importance of prior exposure to entrepreneurial role models in the decision to start and pursue entrepreneurial careers, the mechanism through which role models strengthen entrepreneurial intentions has not been fully understood. Against this background, the current paper investigates the influence of role models, entrepreneurial attitudes and entrepreneurial self-efficacies using a sample of 423 University students in Poland. Through a novel fuzzy-set analysis method, three distinct combinations of the variables under study are found to be most effective for strengthening entrepreneurial intention among university students. By implication, these findings task entrepreneurship educators to concurrently foster the …

Policy Decisions And Tourism: Unintended Consequences Or Deliberate Neglect – Reactions To The Ban On Term Time Holidays In The Uk’S South West, A Walmsley

Plymouth Business School

This study explores reactions of the tourism industry in the UK’s South West to a change in regulations governing term time leave. It serves as an example of the impact of non-tourism specific policy making on tourism. Data were collected from 260 tourism firms via an online survey. Findings confirm a largely negative response to the change in regulations. The study illustrates divergent reactions to the regulations within one stakeholder group, here the tourism sector and by implication highlights the limitations of a naïve application of stakeholder theory. The study also offers insights into the nature of resilience within the …

The Paleolimnologist's Guide To Compound-Specific Stable Isotope Analysis – An Introduction To Principles And Applications Of Csia For Quaternary Lake Sediments, J Holtvoeth, Jh Whiteside, S Engels, Fs Freitas, Et Al

School of Geography, Earth and Environmental Sciences

the stable isotope composition of key chemical elements for life on Earth (e.g., carbon, hydrogen, nitrogen, oxygen, sulfur) tracks changes in fluxes and turnover of these elements in the biogeosphere. Over the past 15–20 years, the potential to measure these isotopic compositions for individual, source-specific organic molecules (biomarkers) and to link them to a range of environmental conditions and processes has been unlocked and amplified by increasingly sensitive, affordable and wide-spread analytical technology. Paleoenvironmental research has seen enormous step-changes in our understanding of past ecosystem dynamics. Vital to these paradigm shifts is the need for well-constrained modern and recent analogues. …

Transforming Rehabilitation: The Impact Of Austerity And Privatisation On Day-To-Day Cultures And Working Practices In 'Probation', Samantha Walker, Jill Annison, Sharon Beckett

Plymouth Business School

Viewed as a culmination of broader neoliberal governance within the UK, this paper examines the impact of the government’s Transforming Rehabilitation (TR) agenda on day-to-day working cultures at the frontline of probation work. TR has brought with it extensive structural and cultural changes to probation work in England and Wales. Once a single public-sector service with a social welfare ethos of ‘advise, assist and befriend’, probation has been dismantled, partially privatised and culturally transformed into a collection of fragmented, target-driven organisations, divided according to risk and with an official rhetoric emphasising public protection. The implications of TR are now starting …

Civic Learning In Conversation: The Common Ground Of Difference, Robert Brown, Paul Warwick

School of Art, Design and Architecture

Situated in the context of a conversation between the authors, this paper is both a reflection on past community based practice and a statement of intention for the criticality of dialogic space in the development of civic engaged learning. Through addressing a series of questions held in common, we explore lessons learned through our own educational praxis, explore the conceptual underpinnings of our collaboration and conclude with our early conceptualisation of a dialogic civic learning playground called ‘Urban Dialogues’. The intention of this new relational space is to bring staff and students from various faculties within a higher education institution …

Optimal Social Insurance With Informal Child Care, Christine Ho

Research Collection School Of Economics

The possibility of engaging in household child care may exacerbate the incentives of parents and grandparents to falsely claim disability benefits as households also get to save on formal child care costs. This paper considers a multi-generational family model with persistence in privately observed shocks and presents an efficient implementation case for subsidizing formal child care costs of the disabled. An implementation of the optimal scheme that consists of capped formal day care subsidies, non-linear income taxation and asset-testing is proposed. Simulations based on a parametrization that targets key features of the US labor and child care markets suggest that …

The International Penetration Of Ibusiness Firms: Network Effects, Liabilities Of Outsidership And Country Clout, Liang Chen, Noman Shaheer, Jingtao Yi, Sali Li

Research Collection Lee Kong Chian School Of Business

The burgeoning of ibusiness firms in the modern digital economy challenges the received internationalization theory. Given that ibusinesses such as social networking sites create value by providing a digital platform for users to interact with one another, we employ a user-network perspective and externalization logic, suggesting that ibusinesses' internationalization process depends critically on users' collective interactions, instead of being solely driven by firms' market commitments, as noted by the Uppsala model. However, ibusinesses may suffer from liabilities of outsidership due to the boundedness of international network effects. Drawing on social network theory, we demonstrate that such liabilities can be mitigated …

Maximum Likelihood Estimation For The Fractional Vasicek Model, Katsuto Tanaka, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This paper is concerned about the problem of estimating the drift parameters in the fractional Vasicek model from a continuous record of observations. Based on the Girsanov theorem for the fractional Brownian motion, the maximum likelihood (ML) method is used. The asymptotic theory for the ML estimates (MLE) is established in the stationary case, the explosive case, and the null recurrent case for the entire range of the Hurst parameter, providing a complete treatment of asymptotic analysis. It is shown that changing the sign of the persistence parameter will change the asymptotic theory for the MLE, including the rate of …

Forecasting Equity Index Volatility By Measuring The Linkage Among Component Stocks, Yue Qiu, Tian Xie, Jun Yu, Qiankun Zhou

Research Collection School Of Economics

The linkage among the realized volatilities across component stocks are important when modeling and forecasting the relevant index volatility. In this paper, the linkage is measured via an extended Common Correlated Effects (CCE) approach under a panel heterogeneous autoregression model where unobserved common factors in errors are assumed. Consistency of the CCE estimator is obtained. The common factors are extracted using the principal component analysis. Empirical studies show that realized volatility models exploiting the linkage effects lead to significantly better out-of-sample forecast performance, for example, an up to 32% increase in the pseudo R2. We also conduct various forecasting exercises …

Limit Theory For Moderate Deviations From Integrated Garch Processes, Yubo Tao

Research Collection School Of Economics

This paper develops the limit theory of the GARCH(1,1) process that moderately deviates from IGARCH process towards both stationary and explosive regimes. The asymptotic theory extends Berkes et al. (2005) by allowing the parameters to have a slower rate of convergence. The results can be applied to unit root test for processes with mildly-integrated GARCH innovations (e.g. Boswijk (2001), Cavaliere and Taylor (2007, 2009)) and deriving limit theory of estimators for models involving mildly-integrated GARCH processes (e.g. Jensen and Rahbek (2004), Francq and Zakoïan (2012, 2013).

Asia is leading the way in digital asset markets, but individual countries are taking markedly different paths toward regulation and management in establishing themselves as cryptocurrency hubs, balancing innovation and regulation. Investors should be vigilant about the risks associated with alternative capital-raising methods.

Central Place Theory And The Power Law For Cities, Wen-Tai Hsu, Zou Xin

Research Collection School Of Economics

This chapter provides a review of the link between central place theory and the power laws for cities. A theory of city size distribution is proposed via a central place hierarchy a la Christaller (1933) either as an equilibrium results or an optimal allocation. Under a central place hierarchy, it is shown that a power law for cities emerges if the underlying heterogeneity in economies of scale across good is regularly varying. Furthermore, we show that an optimal allocation of cities conforms with a central place hierarchy if the underlying heterogeneity in economies of scale across good is a power …

Specific Job Search Self-Efficacy Beliefs And Behaviors Of Unemployed Ethnic Minority Women, Greet Van Hoye, Edwin A. J. Van Hooft, Jolien Stremersch, Filip Lievens

Research Collection Lee Kong Chian School Of Business

This two‐wave field study draws from social cognitive theory to investigate the specific job search self‐efficacy beliefs and behaviors of unemployed ethnic minority women in the Netherlands. We go beyond prior job search research that predominantly used white samples and conceptualized job search self‐efficacy and behavior as global, unidimensional constructs. We found that networking self‐efficacy and Internet self‐efficacy were the main predictors of ethnic minority women’s job search behaviors. Moreover, the more time they spent on contacting employment agencies and looking at job ads the more job offers they received. Finally, time spent on job ads was more positively related …

Prevalence, Patterns And Factors Associated With Hypertensive Crises In Mulago Hospital Emergency Department; A Cross-Sectional Study, Martha Sajatovic

Faculty Scholarship

Background: Hypertension is increasing in sub-Saharan Africa (SSA) and it’s the single most important modifiable stroke risk factor, yet it’s control is not routinely emphasized. The prevalence, pattern and factors associated with hypertensive urgencies and emergencies in Uganda is not well established. A cross-sectional study, was conducted between November 2015 and February 2016, using a complete clinical examination and pre-tested standardized questionnaire subjects were enrolled. The prevalence of hypertensive crises and associations of demographic and clinical factors determined using logistic regression. Results: The prevalence of hypertensive crises was 5.1%, (203/4000) of all admissions at the medical section of the accident …

For this edition of “Ask a Feminist,” Cynthia Enloe-feminist, activist, writer, scholar, and research professor at Clark University-speaks with special issue editors Suzanna Danuta Walters, Ratna Kapur, and Agnieszka Graff about the relations between gender and militarism and imperialism, in particular about the role of gender in the rise of the imperialist, fascist (or neofascist), populist (or neopopulist) social movements that seem to be spanning the globe.

Hosting As Shelter During Displacement: Considerations For Research And Practice, Cynthia Caron

Sustainability and Social Justice

Hosting or local families taking in displaced families is an important way to shelter persons displaced during war or by natural disaster. While field-level evidence of hosting is on the rise, academic and policy-related scholarship on hosting is scant. Based on an extensive literature review and supplemented by the author’s own work experience in the humanitarian sector, this paper identifies and summarizes ten aspects that shape the hosting environment and its associated support programs. These aspects provide insight to humanitarian actors that support hosting situations rather than allowing them to play out on their own. These aspects potentially serve (1) …

The Differential Impact Of Interactions Outside The Organization On Employee Well-Being, Devasheesh P. Bhave, Freyr Halldórsson, Eugene Kim, Alexandru M. Lefter

Research Collection Lee Kong Chian School Of Business

We examine two different perspectives of interactions outside the organization: the relational work design perspective and the emotional labour perspective. The relational work design perspective suggests that interactions outside the organization have favourable outcomes for employees, whereas the emotional labour perspective suggests that such interactions have adverse outcomes for employees. Our goal is to reconcile findings from these two research streams. In Study 1, using data from employees working in diverse occupations, we find that interactions outside the organization have a positive indirect effect on employee well‐being via task significance, and a negative indirect effect on employee well‐being via surface …

Scaled Pca: A New Approach To Dimension Reduction, Dashan Huang, Fuwei Jiang, Guoshi Tong, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

The notion that bond risk premium varies with business cycles is challenged once real time macro data are used. In this paper, we argue that the macro factors extracted by using the standard PCA are not the most relevant for forecasting bond risk premium, because the PCA factors are designed to explain the most variation of macro data instead of the variation of bond risk premium. With the latter objective in mind, we propose a scaled PCA (sPCA) approach, which incorporates the information in bond risk premium in the factor extraction procedure. The real time macro sPCA factors have much …

Do Mobile Banner Ads Increase Sales? Yes, In The Offline Channel, Ernst C. Osinga, Menno Zevenbergen, Mark W. G. Van Zuijlen

Research Collection Lee Kong Chian School Of Business

Firms allocate increasingly large budgets to mobile banner advertising. Yet, existing research paid only scant attention to the sales effects of mobile banner ads. In this paper, we fill this gap by determining the offline and online sales impact of a large-scale mobile banner advertising campaign. As part of a geographical field experiment, over 3.5 million mobile banner ads were served to a predetermined geographical area. We determine the offline and online sales effects of the mobile banner ad campaign by analyzing twenty months of sales data for regions covering the entire country of the Netherlands. Relying on a difference-in-difference …

Why Are Americans So Divided On Refugee Policy?, Shilpa Madan, Shankha Basu, Aneeta Rattan, Krishna Savani

Research Collection Lee Kong Chian School Of Business

The U.S. will resettle the lowest number of refugees in fiscal year 2019 since the Refugee Act was passed in 1980. After taking office, President Donald Trump reduced the admission limit from 110,000 in 2017 to 45,000 in 2018, and to 30,000 in 2019. The reduction is not a result of fewer refugees seeking resettlement. On the contrary, the number of people seeking resettlement is on the rise.

Encouraging Help Across Projects, Pascale Crama, Fabian J. Sting, Yaozhong Wu

Research Collection Lee Kong Chian School Of Business

Companies struggle with timely project execution despite employing sophisticated management methods. Although help across projects is critical for time performance, it has not been explicitly incorporated into project management (PM) systems. We model a PM system, based on an innovative real-life practice, that both incorporates and shapes project managers’ helping behavior. A help process is at the core of this system, in which project managers may ask for and provide help while top management facilitates such exchanges. We find that companies should take a nuanced approach when designing help exchange and time-based incentives in tandem. A company that faces high …

Does Foreign Direct Investment Lead To Industrial Agglomeration?, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu

Research Collection School Of Economics

This paper studies the effect of foreign direct investment (FDI) on industrial agglomeration.Using the differential effects of FDI deregulation in 2002 in China on different industries, we find that FDI actually affects industrial agglomeration negatively. This result is somewhat counter-intuitive, as the conventional wisdom tends to suggest that FDI attracts domestic firms to cluster for various agglomeration benefits, in particular technology spillovers. To reconcile our empirical findings and the conventional wisdom, we develop a theory of FDI and agglomeration based on two counter-veiling forces. Technology diffusion from FDI attracts domestic firms to cluster, but fiercer competition drives firms away. Which …

An Exploration Of Transportation Terrorist Stabbing Attacks, Brian Michael Jenkins, Bruce R. Butterworth, Jean-François Clair, Joseph R. Trella Iii

Mineta Transportation Institute

In his August 22, 2018 message to supporters of the Islamic State of Iraq and [greater] Syria (ISIS), Abu Bakr al-Baghdadi implored ISIS fighters in Syria and Iraq as well as those on various jihadist fronts in Africa, the Middle East, and Asia not to be dismayed by military setbacks suffered by the Islamic State, but to continue fighting, confident that Allah would ultimately reward those who remained steadfast with victory. In the same message, he exhorted homegrown jihadists abroad— “the fierce lions in the lands of the Cross—Canada, Europe, and elsewhere” to carry out simple attacks within their limited …
