Abstract In this paper, we review recent advances in experimental auctions and provide practical advice and guidelines for researchers. We focus on issues related to randomisation to treatment and causal identification of treatment effects, design issues such as selection between different elicitation formats, multiple auction groups in a single session and house money effects. We also discuss sample size and power analysis issues in relation to recent trends in experimental research about pre-registration and pre-analysis plans. We position our discussion with respect to how the agricultural economics profession could benefit from practices adapted in the experimental economics community. We then present the pros and cons of moving auction studies from the laboratory to the field and review the recent literature on behavioural factors that have been identified as important for auction outcomes.

Abstract Background: The worldwide pandemic COVID-19 has produced a wealth of research more rapidly after the outbreak. In just a couple of months, there is a rise in several studies on Coronavirus, adding up to the scholarly literature.Method: The current study attempts to Scientometric analyze very recent literature on Coronaviruses just before and after the outbreak. Besides, the objective of this exploration was to assess the global research progress on Coronavirus in recent times. The current research is an analytical descriptive study using Scientometrics. The study sample includes research papers about the Coronavirus indexed in Web of Science (WoS) database from January 1, 2019 to May 14, 2020. The records with topic search (includes Title, Abstract, Keywords and Keywords Plus) “coronavirus” were extracted. These data were analyzed by MS Excel and the visualizations were created using TableauResult: The results showed that 2551 scientific literature about the Coronavirus was indexed in WoS. A considerable number of these articles were published in journals such as the Journal of Medical Virology, Viruses, Nature, and Lancet. Authors from China, USA and Italy were the most prolific authors. About 47.51% articles received total of 11435 citations with an average of 9 citations, which indicates that nearly half articles were cited in another publication. The highest and lowest citations for these articles were 737 and 1, respectively.Conclusion: These results show a high rate of research on Coronavirus.

Lubrication Conditions

To simulate today’s complex tribo-contact scenarios, a methodological breakdown of a complex design problem into simpler sub-problems is essential to achieve acceptable simulation outcomes. This also helps to manage iterative, hierarchical systems within given computational power. In this paper, the authors reviewed recent trends of simulation practices in tribology to model tribo-contact scenario and life cycle assessment (LCA) with the help of simulation. With the advancement of modern computers and computing power, increasing effort has been given towards simulation, which not only saves time and resources but also provides meaningful results. Having said that, like every other technique, simulation has some inherent limitations which need to be considered during practice. Keeping this in mind, the pros and cons of both physical experiments and simulation approaches are reviewed together with their interdependency and how one approach can benefit the other. Various simulation techniques are outlined with a focus on machine learning which will dominate simulation approaches in the future. In addition, simulation of tribo-contacts across different length scales and lubrication conditions is discussed in detail. An extension of the simulation approach, together with experimental data, can lead towards LCA of components which will provide us with a better understanding of the efficient usage of limited resources and conservation of both energy and resources.

Key Events

Abstract The first half of this review examines the boundary between endocrinology and embryonic development, with the aim of highlighting the way hormones and signaling systems regulate the complex morphological changes to enable the intra-abdominal fetal testes to reach the scrotum. The genitoinguinal ligament, or gubernaculum, first enlarges to hold the testis near the groin, and then it develops limb-bud-like properties and migrates across the pubic region to reach the scrotum. Recent advances show key roles for insulin-like hormone 3 in the first step, with androgen and the genitofemoral nerve involved in the second step. The mammary line may also be involved in initiating the migration. The key events in early postnatal germ cell development are then reviewed because there is mounting evidence for this to be crucial in preventing infertility and malignancy later in life. We review the recent advances in what is known about the etiology of cryptorchidism and summarize the syndromes where a specific molecular cause has been found. Finally, we cover the recent literature on timing of surgery, the issues around acquired cryptorchidism, and the limited role of hormone therapy. We conclude with some observations about the differences between animal models and baby boys with cryptorchidism.

AbstractMorale and faculty development are closely related. The agricultural economics profession must decide what it is about. There is room to practice the principle of comparative advantage and allow a degree of specialization in teaching, extension, and research. To continue in the role of an applied discipline, there must also be an opportunity for the young professional to establish rapport with, and understanding of, the private sector and the policy-making arena. If that is to happen, there must be encouragement in the institutional setting and by faculty colleagues who respect the importance of investment in building rapport and in establishing credibility. If that environment is present, morale should be good and faculty development will occur.

The Impact

Most members of the agricultural economics profession are aware of the changes that are taking place in society and the impact of these changes on our programs, particularly graduate and undergraduate training programs. Certainly the journals of our profession have included many articles relating to our changing mission and the changes that are occurring or should occur in our programs. The next section of this paper contains a brief review of some of these trends in order to establish the need for a new degree, which is described and discussed in the final two sections of the paper.
