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. Keywords: Quantum Computing | NP-Hard Problem | Travelling Tournament Problem | Simulated annealing |

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. Keywords: Overconfidence | Tournament | Hindsight bias | Curse of knowledge | Information projection | Beliefs | Entrepreneurship |

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. Keywords: Tournament incentives | Fairness preference | Large-scale water diversion project | Principle-agent theory |

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.

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.

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. Keywords: Energy efficiency | Pollutant emissions | Economic performance | Promotion Tournament | Promotion incentive | Evolution trend |

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.

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.
