PhD student experiences with the impostor phenomenon in STEM

Devasmita Chakraverty

International Journal of Doctoral Studies

Aim/Purpose

This US-based study explored various facets of impostor phenomenon experienced during PhD training in science, technology, engineering, and mathematics (STEM). Specifically, the purpose of this research was to identify certain experiences that trigger this phenomenon.

Background

Competent high-achievers who do not believe in their efforts leading to accomplishments sometimes experience the impostor phenomenon. It is characterized by the notion that one has fooled others into overestimating their ability, not attributing one’s accomplishments to ability, and living with the fear of being discovered as a fraud.

Methodology

Data were collected using convenience and snowball sampling. Qualitative, semi-structured interviews from 90 PhD students were analyzed thematically.

Contribution

Study findings contribute to a less-understood area of what constitutes triggers for the impostor phenomenon among PhD students in STEM fields.

Findings

Participants described the following themes that triggered impostor phenomenon during PhD training: 1) Progress and public recognition, 2) Comparing oneself with others, 3) Developing skills: public speaking and scientific writing. 4) Application of new knowledge, and 5) Asking for help.

Recommendations for Practitioners

PhD faculty, mentors, advisers, and administrators should be cognizant of the triggers that could give rise to the impostor phenomenon among their students. Professional development activities for students could focus on earlier and more rigorous training for improving scientific communication.

Recommendation for Researchers

Future research should continue to explore if other stakeholders in academia such as postdoctoral trainees and faculty also experience similar stress due to the impostor phenomenon.

Impact on Society

Institutes of higher education should continue to focus on improving student mental health and retention rates, alleviating some of the PhD training stressors by designing interventions that improve students’ mindset and self-efficacy.

Future Research

Findings point to avenues for further research on how to support those with impostor phenomenon. Future research could explore the topic in other disciplines outside STEM and examine if long-term interventions could mitigate impostor-feelings, including the nature and length of interventions that could be helpful.

Alternate solution approaches for competitive hub location problems

Richa Tiwari, Sachin Jayaswal, and Ankur Sinha

European Journal of Operational Research

In this paper, we study the hub location problem of an entrant airline that tries to maximize
its share in a market with already existing competing players. The problem is modelled as a nonlinear
integer program, which is intractable for off-the-shelf commercial solvers, like CPLEX and
Gurobi, etc. Hence, we propose four alternate approaches to solve the problem. The first among
them uses the Kellys cutting plane method, the second is based on a mixed integer second order
conic program reformulation, the third uses the Kellys cutting plane method within Lagrangian
relaxation, while the fourth uses second order conic program within Lagrangian relaxation. The
main contribution of this paper lies in the fourth approach, which along with refinements is the
most efficient. Many of the problem instances that were not solvable using standard techniques,
like the Kellys cutting plane method, have been solved in less than 2 hours of CPU time within
1% optimality gap.

The doctrine of frustration under section 56 of the Indian Contract Act

M P Ram Mohan, Promode Murugavelu, Gaurav Ray, and Kritika Parakh

Indian Law Review

The performance of obligations under a contract may be hindered by unexpected supervening events, leading to contractual uncertainties. The doctrine of frustration paves the way for a just consequence of such an unfortunate event, which has happened without any fault of the contracting parties. The doctrine fills the void in a contract regarding supervening events, based on principles of fairness and equity. Considering the large implications on the obligatory and binding nature of a valid contract, it becomes important to analyse the factors that guide the courts to determine its application. Unlike common law, the Indian Contract law explicitly incorporates the doctrine of frustration under section 56 of the Contract Act. However, the evolution of this doctrine in India has been greatly influenced by English law. This paper attempts to restate the law on the doctrine of frustration as applicable in India.

Right of recourse claims based on latent defects in the nuclear energy sector in India: Brace yourself for fact-intensive disputes

M P Ram Mohan and Els Reynaers

The University of Pennsylvania Asian Law Review

This working paper is focused on trying to interpret the meaning of "latent defects" and analysing how a case were to unfold if an operator of nuclear installation were to exercise its right of recourse against a supplier in the event of supply of equipment or material with latent defects, as envisaged under the unique Section 17(b) of the Civil Liability for Nuclear Damage Act, 2010 (CLND Act), as adopted by the Indian Parliament. Therefore, this paper presumes and builds on the assumption of some prior knowledge of general nuclear law principles as well as the CLND Act and related debates. We welcome comments on any part of the paper.

Ripples on financial networks

Sudarshan Kumar, Avijit Bansal, and Anindya S. Chakrabarti

The European Journal of Finance

In the financial markets, asset returns exhibit collective dynamics masking individual impacts on the rest of the market. Hence, it is still an open problem to identify how shocks originating from one particular asset would create spillover effects across other assets. The problem is more acute when there is a large number of simultaneously traded assets, making the identification of which asset affects which other assets even more difficult. In this paper, we construct a network of the conditional volatility series estimated from asset returns and propose a many-dimensional VAR model with unique identification criteria based on the network topology. Because of the interlinkages across stocks, volatility shock to a particular asset propagates through the network creating a ripple effect. Our method allows us to find the exact path the ripple effect follows on the whole network of assets.
