Cognition and psychology have become central issues in economics. While this interest represents a radical change in economic theory, it does have a useful history that we believe is only partially recognized by contemporary economists. Although it is customary to cite Herbert Simon's important work in this regard,¹ we suggest Hayek's earlier work The Sensory Order (1952) should enjoy similar billing.

The correlations between mechanical behaviour, tensile strength, and rock parameters of metasedimentary rock samples in Karak, Pahang’s New Austrian Tunnelling Method (NATM) were statistically evaluated from the rock mechanic laboratory works at the selected sections around 2,000 m of the tunnel (named as NATM-1). According to a statistical analysis, lithotypes, geological structures, and region geology have a significant impact on the mechanical behaviour of the metasedimentary rock. In the Brazilian test, the fracture behaviour of the disc specimens was highly related to the reliability and precision of the experimental data by validations of methods. In this work, the impact of different loading methods and rock lithotypes on the failure mechanism of Brazilian discs was examined utilising five different metasedimentary rock types and three different loading methods. During the loading operation, the strain and displacement fields of the specimens were recorded and evaluated using a computerised strain gauge system. The rock types, according to experimental data, have a significant impact on the peak load and deformation properties of Brazilian discs. With the method below, tensile strength point of a disc specimen is clearly regulated by the material stiffness and tensile–compression ratio. Seismic occurrences have had a substantial impact on changing the rock and exerting forces that may affect its mechanical characteristics as well as its vulnerability to weathering effects or discontinuities. As a result, the goal of this study is to look into the connection between rock mechanics and metasedimentary rock stress analysis in NATM-1, Karak, Pahang.

Strategic Management, Business Ethics.

This case is suitable to be used in advanced undergraduate and MBA/MSc level.

The case accentuates the challenges faced by Geetanjali Woollens in its mechanical recycling business which is proving detrimental to its African business expansion plans. The case is developed from the episodes of divergence in January 2018 when the buyers’ non-acceptance of mechanically recycled products initiated a managerial dilemma between “business sustenance” and “sustainable business” for Geetanjali Woollens. Being associated with the recycling business for more than 25 years, Madhukar Ghosh, the General Manager at Geetanjali Woollen recycling unit, was delving upon practical, supply-chain-wide solutions to generate standard acceptance norms for mechanically recycled textiles. For him, ethical purpose of business existence was equally important as the profit motive. Bringing operational clarity and standardized regulatory framework still seemed a big challenge for international policymakers and torchbearers of environmental responsibility, and Governments and NGOs popularizing green initiatives. Lack of policy guidelines for business behavior was exacerbating the business functioning. Madhukar knew that consistent buyer policies and standard regulatory framework could clear some mist and induce maturity in the concept of circular economy. Some formalizations were expected till the end of December 2018, if the deadlines did not get pushed further.

The objectives of this case are as follows:

• to highlight the limitations that recycled apparel and textile products have and the concerns that emerge for buyers, designers, and consumers, due to these limitations;

• to highlight the myopic business vision with which the recycling business is suffering due to the lack of a formalized regulatory framework, which in turn is creating various system barriers and making recycling business an unattractive proposition;

• to appreciate the contribution of mechanical recycling of post-consumer textile waste as a closed-loop manufacturing technique in recouping the eco-impacts of increased disposal of apparel and textile products; and

• to promote discussions for innovative solutions for limitations and concerns related to substances of concern in the recycling business and deliberations for a more effective tracking of such substances to facilitate buyer acceptance of mechanically recycled products.

We investigate the relationship among the Dark Triad personality traits, ethical fading, and unethical behavior. Our findings suggest that Machiavellianism and psychopathy have a significant relationship with ethical fading such that individuals with high Machiavellianism are more likely to exhibit ethical fading, and individuals with high psychopathy are less likely to exhibit ethical fading. We do not find a significant association between narcissism and ethical fading. In the supplemental analyses, we investigate whether ethical fading leads to more unethical behavior (i.e., fraudulent reporting) and if it mediates the effect of Machiavellianism and psychopathy on unethical behavior. Our findings suggest that, while all the dark traits have a direct effect on unethical behavior, only Machiavellianism has an indirect effect that flows through ethical fading.

I am indebted to Anthony Waterman for identifying the largely illegible phrase cuius regio, eius religio, found near the end of Ostrander’s notes. Waterman writes, in explanation, apropos of Martin Luther: Lit. ‘whatever of the king, so of the religion’: it means that L. thought (being the Erastian he was), that the religion of a country should be that of its sovereign prince. Note: (a), the assumption, almost universal at that time, that there can be only ONE church in any Christian nation; and (b) the assumption, standard until the Scottish Enlightenment I should think (though people like Locke begin to chip away at it) that – as Louis XIV put it with admirable economy, ‘l’etat c’est moi’ (Waterman to Samuels, December 12, 2002).

The paper published below was prepared by Taylor Ostrander for Frank Knight’s course, Economic Theory, Economics 301, during the Fall 1933 quarter.

Purpose: The purpose of the study was to gain insight into fans' perceptions, attitudes and behavioural responses toward their favourite college football team in the context of a new beer sponsorship agreement. Specifically, the chapter examines differences in fans' attitudes and behaviours based on their gender, team identification and drinking habits.

Design/methodology/approach: A quantitative, cross-sectional survey design was employed. The sample was comprised of Amazon Mechanical Turk (MTurk) workers who self-identified as college football fans. A hypothetical scenario was used as a manipulation, whereby participants were asked to imagine their favourite college football team had entered into a new alcohol sponsorship agreement while completing a questionnaire.

Findings: Highly identified fans exhibited more positive attitudes and behaviours after being presented with the hypothetical scenario than less identified fans. In terms of gender, female fans had increased attitudes toward sponsorship compared to males, and highly identified females had the most positive attitudes and behavioural intentions toward their favourite teams of any of the four subgroups in the study.

Research limitations/implications: The small sample sizes of some fan subgroups affected statistical power, which may have led to falsely insignificant findings. The range of favourite teams among the participants (50 universities) meant there was likely a high degree of variation between fans' previous experiences with beer/alcohol at college sport venues.

Originality/value: The study offers valuable insight into the intersection of sport fandom and gender in the context of alcohol sponsorship in US college sport, and is also among the first investigations of the effects of team identification on perceptions toward alcohol sponsorship.

Published below are the course reading list and student notes taken by F. Taylor Ostrander in Frank H. Knight’s course, Current Tendencies, Economics 303, at the University of Chicago during Winter term of the 1933–1934 academic year. The reading list is surprisingly casual and uneven in detail among items. The notes are assumed, as usual in these volumes, to be a reasonably accurate summary account of what Knight said.

Research has shown evidence of the use of impression management strategies in corporate disclosures as a means of presumably tempering and swaying investors’ perceptions. These impression management strategies include shifts in the tone used when providing disclosures. However, recent research also provides evidence that such techniques can have a contrary effect when the tone of the message appears to be “too good to be true.” This study explores how the use of optimism and certainty in the Management Discussion and Analysis (MD&A) portion of the annual report affects nonprofessional investors’ investment decisions – a class of investors known to heavily rely on the MD&A portion of annual reports. We theorize a bifurcated effect where optimism and certainty have a positive and direct effect on investor willingness to invest, but at the same time optimism and certainty have a negative indirect effect on willingness to invest that is mediated through decreased perceptions of disclosure credibility. The results provide evidence supporting such a bifurcated effect from the use of tone in management disclosures.
