1 Proposed Quantum AI solution for the Travelling Tournament Problem
راه حل پیشنهادی هوش مصنوعی کوانتومی برای مسئله مسابقات سفر-2020
In this paper, we propose an idea/solution for the Travelling Tournament Problem, which is a unique combinatorial problem tackling both feasibility and optimality of the solution. Being an NP-Hard problem, generating solutions can be extremely cost-ly, with most of the solutions of the said problem having a time complexity of as high as O(n!). Quantum Computing and artificial intelligence, on the other hand, is making great strides, and we believe that the immense computational potential of quantum computing can be used to solve these scheduling problems. Artificial Intelligence and machine learning present us with excellent frame-work strategies that we have envisaged to incorporate in our implementation. In the following paper, we delineate the features of our solution and how we propose to incorporate the quantum and classical aspects of computing.

2 Never underestimate your opponent: Hindsight bias causes overplacement and overentry into competition
هرگز حریف خود را دست کم نگیرید: تعصب عقاید باعث اضافه جای و اضافه کار در رقابت می شود-2020
This study investigates a source of comparative overconfidence, or over placement, which occurs when people overestimate themselves relative to others. We present a simple application of information projection (Madarász, 2012) to show that hindsight bias can lead to over placement and excessive willingness to compete. We run an experiment in which subjects choose between a competitive tournament and piece-rate compensation after observing some of their competitors’ past performance. We exogenously manipulate whether subjects have ex post information about their competitors’ past tasks (hindsight) or not (no hindsight). We find that hindsight bias generates over placement and increases subjects’ valuation of tournament participation by 19%. In line with theory, the additional tournament entry in the hindsight setting is driven by low-performing participants who should not have entered the tournament.

3 Tournament incentive mechanisms based on fairness preference in large-scale water diversion projects
مکانیسم های تشویقی مسابقات بر اساس عدالت در پروژه های بزرگ انتقال آب-2020
Large-scale water diversion project has the characteristics of linear distribution and is usually conducted simultaneously by multiple contractors. A typical principal-agent relationship exists between the project owner and each contractor involved in executing the project. Due to the asymmetry of information and the different interest goals of the owner and contractors, the contractors are likely to engage in opportunistic behavior. This can have a seriously negative effect on the interests of the project owner and the public. In order to solve this problem and optimize contractors’ effort levels, this paper establishes a tournament incentives model operating under the existence of contractors’ fairness preferences, based on the principle-agent theory in the large-scale water diversion project. Also, a tournament incentives compensation distribution scheme is designed. The scheme is based on each agent’s ranking and degree of fairness preference. The results show that multiple contractors will be more inclined to put forth optimal effort after tournament incentives mechanism is introduced. Moreover, contractors’ optimal effort levels will increase as the degree of the incentive compensation gap between the two contractors increases. The study finds that the incentive coefficient for both top-ranked and second-ranked contractors should increase in line with corresponding increases in fairness preference degrees. This method will help to ensure that contractors put forward their optimal effort level, indirectly causing an increase in the total output performance of a large-scale water diversion project, thus achieving a win-win situation. Finally, the study’s conclusions are verified through a research study. The findings offer new insights for the development of stakeholder management between the owner and multi-contractor in large-scale water diversion projects.

4 Impacts of promoting sustainable entrepreneurship in generic business plan competitions
تأثیرات ارتقا کارآفرینی پایدار در مسابقات برنامه کسب و کار عمومی-2020
Entrepreneurs and start-ups are key actors in implementing environmental innovation and new approaches in cleaner production. Therefore, the integration of sustainability considerations in early phases of a new venture is important. Insights on how this can be effectively implemented in start-up support systems are scarce and represent a research gap. Business plan competitions (BPCs) constitute an important element in entrepreneurial support systems, and are a powerful force in driving entrepreneurial activity. Up till now, it is unclear whether BPCs can actually influence the sustainability orientation of participating entrepreneurs and the sustainability performance of their ventures. The purpose of this work is to clarify whether the integration of sustainability goals and considerations into generic BPCs has an impact on the business activities of participating entrepreneurs and start-up teams. For our investigation we conducted a survey of the more than 1000 participants in the Business Plan Wettbewerb Berlin Brandenburg, which is the oldest and biggest generic business plan competition in Germany. For the analysis we use a structural equation model and apply the partial-least-squares method. Findings reveal that the promotion of sustainability in generic BPCs have an impact on the integration of sustainability in start-up business activity. Thus, from a sustainability point of view it makes sense to explicitly integrate sustainability into the concrete support offerings of generic BPCs. Our research contributes to cleaner production research by providing new insights on context factors in early (seed and start-up) phases of a new venture.© 2020 The Authors.

5 Graduate students mentoring undergraduate students’ business innovation pitches
دانشجویان مقطع کارشناسی ارشد در زمینه نوآوری تجاری دانشجویان مقطع کارشناسی راهنمایی می کنند-2020
Pitch competitions are commonplace throughout undergraduate and graduate entrepreneurship curricula. Although they are valuable exercises, advancements are available to further their usefulness and reach a wider audience. Accordingly, we developed an experiential learning ex- ercise rooted in the tenets of corporate entrepreneurship that allows for greater collaboration, learning, and critical thinking. In the exercise, undergraduate student groups develop and present an innovative initiative, then are scored and mentored by MBA student groups prior to the final pitches. The benefits include improved student learning by undergraduate students from grad- uate student mentors as well as improved mentoring and leadership skills for graduate students through the practical and experiential process of helping undergraduate students improve their pitches.

6 Promoting the polluters? The competing objectives of energy efficiency, pollutant emissions, and economic performance in Chinese municipalities
تبلیغ آلاینده ها؟ اهداف رقیب بهره وری انرژی ، انتشار آلاینده ها و عملکرد اقتصادی در شهرداری های چین-2020
With the rapid development of Chinas economy, energy efficiency and pollutant emissions have also entered our horizons and become two big issues. To explore the impacts that these three factors have on the promotion probability of municipal party secretaries, we have collected the data of 810 municipal party secretaries with position changes in the period of 2005–2015 and mainly adopted the probit model to conduct our empirical tests. Our results are as follows: (1) Higher economic performance, higher energy efficiency and lower pollution emissions can significantly increase the promotion probability of municipal party secretaries; (2) these three correlations evolve differently, the impact of economic performance declines slightly but always predominates, the impact of pollutant emission tends to grow while that of energy efficiency continues to decrease. This research provides a dynamic understanding of Chinese local officials’ promotion incentive and their trade-off among economy, energy and environment, which would be a valuable supplement for Institution Change Theory and an important reference for other countries with similar developing dilemma.

8 The effects of tournament horizon and the percentage of winners on social comparisons and performance in multi-period competitions
تاثیرات افق مسابقات و درصد پیروزی روی مقایسه های اجتماعی و عملکرد در رقابت های چند - دوره ای-2018
We examine the effects of two important tournament design features, tournament horizon and percentage of winners, on social comparisons and performance in a multi-period setting. Prior research has individually examined these two features, but has not examined their joint effects. Replicating prior research, we predict that a higher percentage of winners will result in better performance than a lower percentage of winners by inducing more social comparisons. We also predict that grand tournaments will result in better performance than repeated tournaments through their effects on the extent to which competitors will engage in social comparisons. We expect that relative to repeated tournaments, grand tournaments will encourage more social comparisons because the performance feedback provided to competitors will be more indicative of the likelihood of future period outcomes (i.e., winning or losing) than in a repeated tournament. We also examine the extent to which the percentage of winners moderates the strength of the predicted relations among tournament horizon, social comparisons and performance. Finally, we predict that in repeated tournaments using a higher percentage of winners will be more effective at sustaining effort in later periods but that these effects will be weaker for grand tournaments. Results from a laboratory experiment with 400 undergraduate student participants support these predictions. Moreover, we find no evidence that the percentage of winners influences the impact of tournament horizon on social comparisons or overall performance. We identify implications for theory and practice.

10 Economics meets psychology: Experimental and self-reported measures of individual competitiveness
ملاقات اقتصاد و روانشناسی : اقدامات آزمایشی و خود گزارش شده از رقابت فردی-2017
This study examines the relationship between economic and psychological approaches to measure individuals competitiveness. While psychologists typically use self-reported psychometric scales, economists tend to use behavioral measures obtained from economic experiments, where subjects confronted with specific paid tasks have to select into either a competitive or a piece-rate payment scheme. Both measurement approaches have remained largely isolated from one another. We demonstrate that a standard behavioral measure and a psycho metric scale of individual competitiveness are positively associated, but distinguishable with respect to the role of personal development motives. While self-reported competitiveness also emerges from personal development motives, the behavioral measure does not reflect such motives. The distinction between both measures is validated based on divergent associations with personality and interests in a competitive career.
