United Or Divided? Antecedents Of Board Cohesiveness In International Joint Ventures, Rene Olie, Elko Klijn, Hugo V. Leenders Jan 2020

United Or Divided? Antecedents Of Board Cohesiveness In International Joint Ventures, Rene Olie, Elko Klijn, Hugo V. Leenders

Management Faculty Publications

We combine board process research with the literature on international joint ventures (IJVs) by investigating the antecedents of cohesiveness of IJV boards of directors. Even though that corporate governance scholars have frequently emphasized the crucial role of cohesiveness for board effectiveness, cohesiveness has received limited research attention. We investigate the determinants of board cohesiveness by specifically focusing on an understudied organizational form, namely the IJV. IJVs are formed by two or more independent parent organizations originating from geographically dispersed home countries with disparate cultural backgrounds. We argue that the inherent features related to the international and partner-specific context of these …


Greenfield Or M&A? An Institutional And Learning Perspective On The Establishment Mode Choice Of Chinese Outward Investments, Ilan Alon, Stefano Elia, Shaomin Li Jan 2020

Greenfield Or M&A? An Institutional And Learning Perspective On The Establishment Mode Choice Of Chinese Outward Investments, Ilan Alon, Stefano Elia, Shaomin Li

Management Faculty Publications

We develop and test a model of Chinese greenfield investments using institutional and learning theories. Both the host country institutional context and the firm's international characteristics affect the establishment mode. Using 152 Chinese emerging market multinationals (EMNEs) with 401 subsidiaries distributed in 26 countries from 2003 to 2013, we build a database of 284 pairs of host country/Chinese firms to test two hypotheses. We find that, first, governance environment affects the establishment mode: greenfield investments are preferred over acquisitions in relation-based host markets, and M&As are preferred in rule-based countries. Second, the depth of Chinese EMNEs' international experience (i.e. the …

Impact Of Wind Farms On The Economic And Financial Standing Of The Korsze Commune, Izabela Rogalska, Damian Opalach, Radosław Sańko

Studia i Materiały Wydział Zarządzania Uniwersytet Warszawski

Being an inexhaustible source of ecologically pure energy, wind is gaining an increasingly wider range of applications. This translates into the growing interest of investors in areas endowed with the conditions suitable for developing wind farms. An investment into wind turbines can generate many economic benefits for a local government, chiefly by ensuring higher revenues from real estate taxes. The main objective of this study has been to evaluate the impact of wind farms on the economic and financial standing of the Korsze commune. The study included secondary data obtained from the Municipal Office in Korsze and statistical data from …

Studia i Materiały Wydział Zarządzania Uniwersytet Warszawski

The aim of the article is to present car sharing, with particular emphasis on electric car sharing, as an interdisciplinary research area. This applies not only to social sciences – management (strategy or marketing), sociology, economics (including the sharing economy), consumer psychology, but also to urban planning, engineering sciences (electrical engineering or energy) and, finally, ecology. Only the use of a broader perspective allows the understanding of the importance of car sharing, including electric vehicles, in contemporary social and economic processes. The diagnosis of factors that may affect the widespread use of car sharing, which we treat as an element …

Monografie/Monographs

Przebogata w czasie (ponad dwa tysiące lat) i treści historia fenomenu industrialnego, zwanego „świętokrzyską erą żelaza”, mieści w sobie wiele faz rozwojowych, obfitujących w wydarzenia techniczno-technologiczne oraz gospodarczo-społeczne. Jednakże, choćby tylko pobieżna próba ich sygnalizacji, wykracza poza ramy jednego, nawet opasłego, opracowania. Stąd inicjatorzy cyklu wydawniczego Almanach Świętokrzyski, skupieni wokół jego Rady Programowo-Naukowej oraz autorzy, redaktorzy i wydawca niniejszego tomu piątego, zgodnie wnioskowali o dokonanie próby pokazania kolejnych etapów i faz rozwoju tej ery w postaci następnych, chronologicznie wyznaczonych częściach lub tomach wydawniczych, w miarę możliwości ujednoliconych monograficznie opisywaną problematyką.

Short-Term Exposure To Unmanned Aerial Vehicles Does Not Alter Stress Responses In Breeding Tree Swallows, Bradley D. Scholten, Abigail R. Beard, Hyeryeong Choi, Dena M. Baker

University Faculty Publications and Creative Works

Recent studies suggest that visual and acoustic anthropogenic disturbances can cause physiological stress in animals. Human-induced stress may be particularly problematic for birds as new technologies, such as drones, increasingly invade their low-altitude air space. Although professional and recreational drone usage is increasing rapidly, there is little information on how drones affect avian behavior and physiology. We examined the effects of drone activity on behavior and physiology in adult, box-nesting tree swallows (Tachycineta bicolor). Specifically, we monitored bird behavior during drone flights and in response to a control object and measured telomere lengths and corticosterone levels as indicators of longer-term …

Efficiency Analysis Of A Congested Brazilian Airport Applying Slots Optimization Control: Congonhas Airport Case, Mariana Franco B. Mendes, Rafael Roco De Araujo, Ana Paula Beck Da Silva Etges, Massoud Bazargan

International Journal of Aviation, Aeronautics, and Aerospace

The current slot allocation mechanism in Brazil, based on the International Air Transport Association (IATA) rules, and its supplementary local regulation The National Civil Aviation Agency (ANAC), displays a few issues and limitations (e.g. slot misuse, allocation inefficiencies). Such issues are particularly present in the case of busy airports that works near their maximum capacity for major parts of the day. This inefficiency problem is generated because of the complexity of slot allocation added to the limited decision support available for the Brazilian system. This study focuses on the implementation of an optimal slot model, based on IATA regulations with …

Determinants Of Tax Morale Using Structural Equation Model (Sem), Raymond S. Pacaldo, Rodiel C. Ferrer Jan 2020

Determinants Of Tax Morale Using Structural Equation Model (Sem), Raymond S. Pacaldo, Rodiel C. Ferrer

DLSU Business & Economics Review

This paper analyzes the impact of tax enforcement, trust in government, and demographic characteristics on the tax morale of firms in the Philippines. From the database of Business Environment and Enterprise Performance Survey (BEEPS), 864 firms were taken and analyzed using partial least squares on the structural equation of modeling (PLS-SEM). In the analysis, only trust in government, organizational form, and firm location provided a significant impact to tax morale. Thus, firms pay taxes religiously when the government acts trustworthily. On the other hand, sole proprietorship and Metro Manila firms exhibited lower tax morale as compared to corporations and outside …

Effect Of Moderating Variables: Financial Leverage And Dividend Payout Of Publicly-Listed Property Sector Of The Philippines, Cynthia P. Cudia, Harrison Kendrick L. Chun, Tristan Dranel M. Papa, Raveena S. Tahilramani, Althea R. Tan

DLSU Business & Economics Review

Various studies on the relationship between financial leverage and dividend payout have been conducted; however, different factors affecting this relationship remain unexplored. This study aimed to identify the effect of different firm-specific moderating variables on the relationship between financial leverage and dividend payout of Philippine publicly-listed companies under the property sector for the years 2012–2016. These firm-specific variables were classified into two categories—company profile and financial condition. By employing multiple regression with the interaction model, the results of this study found that business risk has a significant effect on the relationship between financial leverage and dividend payout. Similarly, firm size …


Scenario-Based Strategic Planning For Future Civil Vertical Take-Off And Landing (Vtol) Transport, Woojin Choi, Steven Hampton Jan 2020

Scenario-Based Strategic Planning For Future Civil Vertical Take-Off And Landing (Vtol) Transport, Woojin Choi, Steven Hampton

Journal of Aviation/Aerospace Education & Research

Rapid evolvement of the vertical take-off and landing (VTOL) technology in conjunction with recent robust R&D has demonstrated the technical feasibility of the civil VTOL system as a short-haul mass transit mode. Its combined benefits of a helicopter and a turboprop into one aircraft is expected to become an effective remedy for congested air traffic and difficulties with airport expansions in the metropolitan areas along with the potential benefit to improve accessibility to population centers and remote areas where conventional aircraft cannot access.

In this study, based on a the Political, Economic, Social, Technological, Environmental, and Legal (PESTEL) factors and …

Understanding The Relationship Between Smartphone Addiction And Well-Being: The Mediation Of Mindfulness And Moderation Of Hedonic Apps, Murad Moqbel

Information Systems Faculty Publications

The advent of handheld devices such as smartphones has changed the way we connect, navigate, and entertain and has been recognized as a revolution in information and communication technologies (ICT). Despite the plethora of benefits of this new technology, concerns have been raised about the unintended adverse consequences to well-being in the form of addictive use. Past research has linked smartphone addiction to negative consequences, but it remains unclear how, why, and when (i.e., under what conditions) smartphone addiction, in turn, is related to well-being. This study attempts to fill this void by addressing these questions through the lens of …

Managing The Global Virtual Workforce: Reducing The Liability Of Foreignness, Carol M. Sanchez, Rebekah Arndt Jan 2020

Managing The Global Virtual Workforce: Reducing The Liability Of Foreignness, Carol M. Sanchez, Rebekah Arndt

Peer Reviewed Articles

Effective management of global virtual workforces may reduce the liability of foreignness. As more organizations do business across borders, global workforce effectiveness is critical given logistic, language and cultural distances. Based on theories of global workforces, virtual technology use, cultural differences, and common language policy, we posit that global virtual workforces will better succeed if organizations (1) select appropriate communication technology, (2) train members to navigate cultural differences, and (2) adopt a language policy. We highlight strategies with examples from conversations with managers of several organizations, and we emphasize unexpected benefits to organizations that successfully manage their global virtual workforce.

Improving The M&A Success Rate: Identity May Be The Key, Carol M. Sanchez, Mahendra Joshi, Paul Mudde

Peer Reviewed Articles

Every year companies spend over $4 trillion on mergers and acquisitions (M&As) in spite of the fact that between 70% to 90% of these M&As fail. Both practitioners and scholars are puzzled by these intriguing statistic and have tried to identify the causes of M&A failures. Factors such as inaccurate assessment of financial and operational synergies, lack of clarity in the execution of the integration process, negotiation errors, lack of backup plans, and cultural issues are only a few of the long list of reasons that may lead to such high rate of failure. Evidently, some of these factors have …


Beyond Warm Glow: The Risk-Mitigating Effect Of Corporate Social Responsibility (Csr), Abhi Bhattacharya, Valerie Good, Hanieh Sardashti, John Peloza Jan 2020

Beyond Warm Glow: The Risk-Mitigating Effect Of Corporate Social Responsibility (Csr), Abhi Bhattacharya, Valerie Good, Hanieh Sardashti, John Peloza

Peer Reviewed Articles

Corporate social responsibility (CSR) positively impacts relationships between firms and customers. Previous research construes this as an outcome of customers’ warm glow that results from supporting firms’ benevolence. The current research demonstrates that beyond warm glow, CSR positively impacts firms’ sales through mitigating their customers’ perceptions of purchase risk. We demonstrate this effect across three conditions in which customers’ perceived risk of purchase is heightened, using both secondary data and two lab experiments. Under conditions of greater purchase risk (i.e., recessions, a service context, and longer-term consumer commitments), CSR positively impacts both sales and customer purchase intentions to a greater …


The Differential Role Of Job Demands In Relation To Nonwork Domain Outcomes Based On The Challenge-Hindrance Framework, Jennica R. Webster, Gary A. Adams Jan 2020

The Differential Role Of Job Demands In Relation To Nonwork Domain Outcomes Based On The Challenge-Hindrance Framework, Jennica R. Webster, Gary A. Adams

Management Faculty Research and Publications

The purpose of this study was to meta-analytically test a novel theoretical model examining a dual stressor and dual process model relating demands in the work domain to outcomes in the nonwork domain. The foundation for this model rested upon the challenge-hindrance framework and the role depletion and role enhancement perspectives derived from role theory as applied to the work-nonwork interface. The results show mixed support for the proposed model. In line with the challenge-hindrance framework the effects of challenge stressors were less detrimental than hindrance stressors. However, contrary to what has been reported for work domain outcomes, the net …

Fast Poisson Estimation With High-Dimensional Fixed Effects, Sergio Correia, Paulo Guimarães, Thomas Zylkin Jan 2020

Fast Poisson Estimation With High-Dimensional Fixed Effects, Sergio Correia, Paulo Guimarães, Thomas Zylkin

Economics Faculty Publications

In this paper we present ppmlhdfe, a new Stata command for estimation of (pseudo) Poisson regression models with multiple high-dimensional fixed effects (HDFE). Estimation is implemented using a modified version of the iteratively reweighted least-squares (IRLS) algorithm that allows for fast estimation in the presence of HDFE. Because the code is built around the reghdfe package, it has similar syntax, supports many of the same functionalities, and benefits from reghdfe’s fast convergence properties for computing high-dimensional least squares problems. Performance is further enhanced by some new techniques we introduce for accelerating HDFE-IRLS estimation specifically ppmlhdfe also implements a novel and …
