The determinants of election to the Presidency of the American Economic Association: Evidence from a cohort of distinguished 1950’s economists

Data have been collected on 55 members of the AEA Executive Committees for the years 1950–1960 (inclusive) on a variety of variables that measure the merit and non-merit characteristics of the economists. A logit is estimated in which the dependent variable is a dummy variable for whether an Executive Committee member was ever elected President of the American Economic Association (AEA). The number of publications and citations are important determinants of election. Receiving a PhD from one of the top three schools does not help and living in the South does not hurt. Economists who were older in 1956 were more likely to have eventually been elected to the AEA Presidency.     

Learning from Political Change and the Development of MNCs’ Political Capabilities: Evidence from the Global Mining Industry

Previous studies have suggested that (1) a type of organizational capabilities—namely, political capabilities—are required for multinational corporations (MNCs) to grow in global markets, (2) political capabilities are important for building productive relations with governments in politically risky host countries, and (3) MNCs can develop political capabilities by accumulating foreign experiences. However, empirical studies have found both positive and negative effects of such experiences on global market expansions. This study attributes such mixed findings to our lack of understanding about MNCs’ procurement processes of political capabilities and proposes types of experiences critical for such procurements by focusing on their reactions to political changes in host countries. Using data on the global mining industry and political changes in host countries, we find that MNCs develop political capabilities and thus make entries into politically risky host countries when they accumulate the experience of partially divesting some of their assets after political changes in host countries. We also find that MNCs are less likely to enter such countries if they have more experiences of exiting from host countries following political change.     

Investigating gig workers’ commitment to crowdsourced logistics platforms: Fair employment and social exchange perspectives

Crowdsourced logistics is developing rapidly during and post COVID-19. As key workers of crowdsourced logistics, gig workers' commitment is essential for the sustainable development of gig platforms. Drawing from the social exchange paradigm and organisational identification, this study explores how the five principles of Fairwork provided by crowdsourced logistics platforms (i.e., fair representation, fair management, fair conditions, fair contracts, fair pay) contribute to gig workers' organisational identification, which subsequently influences career satisfaction and career commitment. The study gathered 177 responses from gig workers in Singapore in July 2022. The structural equation modelling findings suggest that factors such as fair conditions, fair pay, fair representation, fair management, and fair contracts have substantial impacts on organisational identification. Moreover, the link between organisational identification and career commitment is partially mediated by career satisfaction. Overall, this study enriches the literature by proposing a suitable theoretical model to explain gig workers' commitment to crowdsourced logistics platforms. Moreover, the empirical results provide implications on the understanding of gig workers’ concerns for gig platforms, as well as policy suggestions for the maintenance of gig workers in the future.     

Reading between the lines of the ‘Responsible Resource Development’ rhetoric: the use of omnibus bills to ‘streamline’ Canadian environmental legislation

In Canada, the use of omnibus budget bills in recent years has grown substantially. In 2012, it was used twice by the Government of Canada. As a result, a number of substantial changes to environmental legislation were introduced with virtually no debate nor compromise. This situation has been criticized for seriously reducing the credibility of the budget process and the authority of Parliament in Canada, as well as undermining the transparency and accountability of the policy-making process. This paper describes how changes to major policies through the use of omnibus bills (all, arguably, in the name of faster project review decisions) affect not only established environmental protection efforts, but also the public and Aboriginal (First Nations, Inuit and Metis) peoples, particularly in terms of their capacity to effectively participate in resource development.

Determinants of consumers’ remanufactured products purchase intentions: Evidence from China

Previous studies have examined the main factors that influence consumer acceptance of remanufactured products based on the theory of planned behaviour (TPB). However, researchers have not yet conducted detailed studies to classify the variables of TPB. In the present research, this gap is addressed by using a TPB model which (1) differentiates attitude into experiential attitude and instrumental attitude, (2) differentiates subjective norm into normative social influence and informational social influence, and (3) differentiates perceived behavioural control into product knowledge, perceived risk, and perceived inconvenience. In this study, past experience and the interaction effect of attitude and subjective norm are also considered. The research results suggest that experiential and instrumental attitude, normative and informational social influence, product knowledge, and past experience are positive determinants of consumers’ purchase intentions toward remanufactured products, while perceived inconvenience and perceived risk are negative determinants. Furthermore, the findings also suggest that the interaction effects of experiential attitude and subjective norms positively affect purchase intentions, whereas the interaction effects of instrumental attitude and subjective norms have a negative effect. Based on the research conclusions, this study concludes with a discussion of proposals for improving consumers’ remanufactured product purchase intentions, implications for product design and manufacturing, limitations of the current study, and recommendations for further research.     

Rejuvenation heat treatment’s influence on the microstructure and properties of superalloys

Rejuvenation heat treatment is an important technology to restore damaged microstructure and properties of superalloys. This investigation is conducted to figure out the effect of rejuvenation heat treatment on the superalloys. The microstructure and micro-hardness of K002 and DZ125 superalloys after different heat treatment procedures were evaluated. The results show that the heating temperature mainly affects the solubility of the carbides and γ′ phases, while the cooling rate has an effect on the morphology of secondary γ′ phase. Owing to the transition of carbides during the work process, rejuvenation heat treatment temperature has little effect on the amount of carbides in damaged alloys. Suggestions for rejuvenation heat treatment are proposed.

The Evidence of Institutional Investors’ Herd Behavior and the Research on Market Simulation

In the context of vigorously developing China’s securities market institutional investors in the period of economic transition,this paper does the empirical research on the herd behavior from the view of the interaction between individual and institutional investors. This paper adopts the standard deviation of trading volume the cross-section to measure herd behavior. The results show that no matter what the market is in bull status and bear status,institutional investors perform herd behavior and with the expansion of the shareholding scale in a bull market,the herd behavior is higher,which suggests that the vigorous development of institutional investors has not eliminated herd behavior. This paper further confirms that there is the endogenous volatility in the market based on an artificial stock market. Finally it is demonstrated the herd behavior of institutional investors cause abnormal fluctuations in the market.

Examining the influence of supply chain glitches on shareholder wealth: does the reason matter?

This paper investigates how different reasons for supply chain glitches influence shareholder wealth. Prior research indicated that supply chain glitches can decrease shareholder wealth by a staggering 10.28%. We argue that the reason for the supply chain glitch is an important moderator for understanding how supply chain glitches affect shareholder wealth. In this paper we re-assess the effect of supply chain glitches on shareholder wealth for a new time period (i.e. 2001–2012) whilst including the moderators from the original study (growth prospects, firm size, debt-equity ratio and timing) and adding the reason for the supply chain glitch as an important new moderator. Our results show that on average supply chain glitches decrease shareholder wealth by 1.94%. Further, our results indicate that supply chain glitches that arise due to regulatory, catastrophic and infrastructural reasons trigger more significant negative reactions in financial markets as compared with glitches that occur from the supply side. We discuss the implications of our findings both for theory building and for business practice, and end with limitations and suggestions for future research.

A Big-Data-based platform of workers’ behavior: Observations from the field

Behavior-Based Safety (BBS) has been used in construction to observe, analyze and modify workers’ behavior. However, studies have identified that BBS has several limitations, which have hindered its effective implementation. To mitigate the negative impact of BBS, this paper uses a case study approach to develop a Big-Data-based platform to classify, collect and store data about workers’ unsafe behavior that is derived from a metro construction project. In developing the platform, three processes were undertaken: (1) a behavioral risk knowledge base was established; (2) images reflecting workers’ unsafe behavior were collected from intelligent video surveillance and mobile application; and (3) images with semantic information were stored via a Hadoop Distributed File System (HDFS). The platform was implemented during the construction of the metro-system and it is demonstrated that it can effectively analyze semantic information contained in images, automatically extract workers’ unsafe behavior and quickly retrieve on HDFS as well. The research presented in this paper can enable construction organizations with the ability to visualize unsafe acts in real-time and further identify patterns of behavior that can jeopardize safety outcomes.     

PLD bioactive ceramic films: the influence of CaO–P2O5 glass additions to hydroxyapatite on the proliferation and morphology of osteblastic like-cells

This work consists on the evaluation of the in vitro performance of Ti6Al4V samples PLD (pulsed laser deposition) coated with hydroxyapatite, both pure and mixed with a CaO–P₂O₅ glass. Previous studies on immersion of PLD coatings in SBF, showed that the immersion apatite films did not present the usual cauliflower morphology but replicated the original columnar structure and exhibited good bioactivity. However, the influence of glass associated to hydroxyapatite concerning adhesion, proliferation and morphology of MG63 cells on the films surface was unclear. In this study, the performance of these PLD coated samples was evaluated, not only following the physical–chemical transformations resulting from the SBF immersion, but also evaluating the cytocompatibility in contact with osteoblast-like MG63 cells. SEM and AFM confirmed that the bioactive ceramic PLD films reproduce the substrate’s surface topography and that the films presented good adherence and uniform surface roughness. Physical–chemical phenomena occurring during immersion in SBF did not modify the original columnar structure. In contact with MG63 cells, coated samples exhibited very good acceptance and cytocompatibility when compared to control. The glass mixed with hydroxyapatite induced higher cellular proliferation. Cells grown on these samples presented many filipodia and granular structures, typical features of osteoblasts.     

An animal study on the bone behaviour of Ca–P-coated implants: influence of implant location

Four different implant materials were installed into the mandibular corner of goats to investigate the trabecular bone response in a mainly unloaded model. The implants were installed using a standardized technique and were left in situ for 12 weeks. One goat had to be sacrificed after surgery because of a broken rib; the other animals healed uneventfully. After sacrifice of the animals, the bone response to the uncoated and the three different Ca–P implants was evaluated histologically and histomorphometrically. Four sections of each implant were evaluated; two were located in the cortical and two in the trabecular bone. Of the 44 retrieved implants, 20 implants appeared to be installed partially in the mandibular canal, as clearly visible on the X-rays. These implants were not used in the histomorphometrical measurements. Histological evaluation showed that the trabecular and cortical bone reactions were similar; there was no significant difference in the percentage of bone contact nor in the amount of bone in contact with the implants. In conclusion this study showed that the mandibular corner is an unsatisfactory model for the installation of implants because of anatomical restrictions. Also, the experiment remained inconclusive about the influence of loading conditions on bone behaviour. Nevertheless, the histological results confirmed the bioactive properties of Ca–P coatings.
