Interplay between constraints and rewards in innovation tournaments: implications for participation

Swanand J. Deodhar

International Journal of Cooperative Information Systems

In this study, we examine how the monetary rewards and competitive constraints that organizers of innovation tournaments incorporate are associated with participation. These two aspects of innovation tournaments are crucial because they represent critical design decisions that the organizers must make beforehand. We show that the reward amount is negatively associated with participation, while the presence of competitive constraints, which “make the competitive landscape less asymmetric”, is positively associated with participation. Furthermore, the study shows that competitive constraints moderate the negative association between reward amount and participation. These findings provide insights into contestant motivation as well as the interdependencies between tournament design choices.

AGV or lift-AGV? Performance trade-offs and design insights for container terminals with robotized transport vehicle technology

Govind Lal Kumawat and Debjit Roy

IISE Transactions

New container terminals are embracing robotized transport vehicles such as lift-automated guided vehicles (LAGVs) and automated guided vehicles (AGVs) to enhance the terminal throughput capacity. Although LAGVs have a high container handling time, they require less coordination with other terminal equipment in comparison with AGVs. In contrast, AGVs are hard-coupled resources, require less container handling times, but operate with high coordination delays in comparison with LAGVs. The effect of such operational trade-offs on terminal performance under various design parameter settings, such as yard block layout and a number of resources, is not well understood and needs to be evaluated at the terminal design phase. To analyze these trade-offs, we develop stylized semi-open queuing network models, which consist of two-phase servers and finite capacity queues. We develop a novel network decomposition method for solving the proposed queuing models. The accuracy of the solution method is validated using detailed simulation models. Using the analytical models, we study the performance trade-offs between the transport vehicle choices: LAGVs and AGVs. Our results show that the throughput capacity of the terminal in the container unloading process increases by up to 16% if LAGVs are chosen as transport vehicles instead of AGVs. However, at certain parameter settings, specifically, when the arrival rate of containers is low, the throughput time performance of the terminal is higher (up to 8%) with AGVs than with LAGVs. We also derive insights on the yard block layout and the technology choice for quay cranes.

Using complier average causal effect estimation to examine student outcomes of the pax good behavior game when integrated with the PATHS curriculum

Catherine P. Bradshaw, Kathan Shukla, Elise T. Pas, Juliette K. Berg, and Nicholas S. Lalongo

Administration and Policy in Mental Health and Mental Health Services Research

A growing body of research has documented a link between variation in implementation dosage and outcomes associated with preventive interventions. Complier Average Causal Effect (CACE; Jo in J Educ Behav Stat 27:385-409, 2002) analysis allows for estimating program impacts in light of variation in implementation. This study reports intent-to-treat (ITT) and CACE findings from a randomized controlled trial (RCT) testing the impacts of the universal PAX Good Behavior Game (PAX GBG) integrated with Promoting Alternative Thinking Strategies (i.e., PATHS to PAX) and PAX GBG only compared to a control. This study used ratings by 318 K-5 teachers of 1526 at-risk children who, at baseline, were rated as displaying the top 33rd percentile of aggressive-disruptive behavior. Leveraging a prior study on these data (Berg et al. in Admin Policy Ment Health Ment Health Serv Res 44:558-571, https://doi.org/10.1007/s10488-016-0738-1 , 2017), CACE was defined as the effect of intervention assignment for compliers, using two compliance cut points (50th and 75th percentile), on posttest ratings of student academic engagement, social competence, peer relations, emotion regulation, hyperactivity, and aggressive-disruptive behavior. The ITT analyses indicated improvements for students in the integrated condition on ratings of social competence compared to the control condition. The CACE analyses also indicated significant effects of the integrated intervention on social competence, as well as academic engagement and emotion regulation for students in high compliance classrooms. These findings illustrate the importance of considering variation in implementation within the context of RCTs.

Implications of land use transitions and climate change on local flooding in urban areas: An assessment of 42 Indian cities

Vidhee Avashia and Amit Garg

Land Use Policy

Urban development induced land transitions affect urban hydrology, resulting in increased flooding risks. Climate change-related precipitation changes are an added complexity to the flood risks of cities. This study examines the role of land use changes in determining the occurrence of urban flooding events across 42 Indian cities under current and future climate change scenarios. Landsat images for 1990, 2000, 2010, and 2017 have been processed using a hybrid classification technique to determine the land use shares for all cities. A typical event-count study using newspaper archives has been conducted to create a flooding event database. A multilevel model employing logistic mixed-effects approach was used. Future projections of the occurrence of flooding events for nine models under three climate change-related Representative Concentration Pathways (RCPs)—2.6, 4.5, and 8.5—and three urban development scenarios have been carried out. The results suggest that cities should preserve the land uses that act as a sponge—the green, open and blue spaces. As these spaces decrease, the projected flooding events increase. Under the RCP 2.6 scenario, the number of flooding events is significantly lower (95 % confidence) than under RCPs 4.5 and 8.5. The expected flooding occurrences between RCP4.5 and RCP8.5 are not significantly different (95 % confidence) for many scenarios, suggesting that Indian cities should aim for a world temperature increase of below 2 °C, or devastating consequences are imminent. This study highlights the need for Indian cities to undertake integrated spatial planning measures for a resilient, sustainable urban future.

Cost-effective achievement of the Paris Agreement's long-term goals requires the unanimous phase-out of coal power generation by mid-century. However, continued investments in coal power plants will make this transition difficult. India is one of the major countries with significant under construction and planned increase in coal power capacity. To ascertain the likelihood and consequences of the continued expansion of coal power for India's future mitigation options, we use harmonised scenario results from national and global models along with projections from various government reports. Both these approaches estimate that coal capacity is expected to increase until 2030, along with rapid developments in wind and solar power. However, coal capacity stranding of the order of 133–237 GW needs to occur after 2030 if India were to pursue an ambitious climate policy in line with a well-below 2 °C target. Earlier policy strengthening starting after 2020 can reduce stranded assets (14–159 GW) but brings with it political economy and renewable expansion challenges. We conclude that a policy limiting coal plants to those under construction combined with higher solar targets could be politically feasible, prevent significant stranded capacity, and allow higher mitigation ambition in the future.

Financial misconduct, fear of prosecution and bank lending

Abhiman Das, Avijit Bansal, and Saibal Ghosh

Economic and Political Weekly

The issue and relevance of financial misconduct and fear of prosecution on the lending behaviour of Indian banks is investigated by combining bank-level financial and prudential variables during 2008–18 with a unique hand-collected data set on financial misconduct and fear of prosecution. The findings indicate that, in the presence of financial misconduct, state-owned banks typically cut back on credit creation and instead increase their quantum of risk-free investment. In terms of magnitude, a 10% increase in financial misconduct lowers lending by 0.2% along with a roughly commensurate increase in investment. In terms of the channels, it is found that private banks increase provisioning to maintain their credit growth, although the evidence for state-owned banks is less persuasive.

Psychological containment of organisational toxicity and its spillovers

Ajeet N Mathur

Organisational & Social Dynamics

Organisational toxicity can thwart creation and sharing of knowledge necessary for collaborations. Psychological phenomena lurking in covert processes affect dynamics of containment and spillovers of organisational toxicity. This study discusses insights from four longitudinal action research studies in organisations across a spectra of technologies and technology intensities to examine containment and spillovers of organisational toxicity. This article concludes that strategic juxtaposition of ends, ways, and means requires sociotechnical structures to provide reliability; techno-economic systems for coping with anxieties around uncertainties of value-adding functions; and, socioeconomic processes for credibility and aesthetics to promote harmony. Together, under certain conditions, this trine of structures, systems, and processes may facilitate mitigation of toxicity with more understanding of the toxicity bred in systems from introjections, projections, transferences, and countertransferences. Sustaining a shared core to cultivate inner awareness and wisdom for the common good requires hermeneutic endeavours to work with unconsciously held phenomenal primary tasks. This article raises new research questions for understanding the scope and limits of these conditions in old and new combinations of scale, growth, and dominance.

Bother me only if the client complains: control and resistance in home-based telework in India

Dharma Raju Bathini and George Mathew Kandathil

Employee Relations: The International Journal

Purpose

The purpose of this paper is to explore the link between operations of organization control and workers’ response to them in case of telework, a technology-embedded new way of working.

Design/methodology/approach

The authors adopted an interpretive approach to explore control and home-based teleworkers’ response in the Indian information technology industry. Interviews and non-participant observations were analysed using constructivist grounded theory.

Findings

The discourse of “telework as a privilege” served as a basis for normative control, helping managers exercise increased technocratic control. Combined with the discourse of “self-responsibility to client”, it led teleworkers to self-subjugate to long/unsocial work hours. However, the simultaneous exercise of technocratic and normative controls resulted in an inconsistency, creating space for teleworker’s resistance to technocratic control. Nonetheless, resistance to technocratic control ironically reinforced normative control.

Originality/value

The authors contribute to the recent discussion on compatibility and coherence of multiple control modes, and their relationship to resistance. The authors show how workers’ selves can be compatible with one control mode while being incompatible with other modes. The authors argue that when workers’ experience incoherence between control modes, they can appropriate the logic underlying compatible control mode(s) to resist incompatible control mode(s). Further, the authors demonstrate how resistance to incompatible control mode(s) can ironically reinforce compatible control mode(s), and thus explicate the micro-processes of control-resistance dialectic. Advancing the emergent understanding of resistance, the authors show that resistance is an exercise of strategic counter-power that seeks to exploit incoherence between control modes and inconsistencies between actions and rhetoric.
