Meetings are conducted by increasingly age-diverse participant groups as the workforces in most industrialized economies are aging due to demographic change. There are at least three reasons why meetings constitute a particularly interesting environment to study intergenerational learning processes, defined as individuals’ joint construction of knowledge through an exchange of information with one or more individuals from different age groups. First, meetings allow us to observe a wide variety of interactions that may foster or inhibit intergenerational learning. Second, the interactions taking place in meetings reflect general organizational practices as well as social exchange and age norms. As such, meetings offer a view through the magnifying glass at the age-inclusive or age-discriminating organizational culture which is interwoven with the engagement of different generations in intergenerational learning processes. Third, organizational members use meetings as an arena for strategic interactions to negotiate their current and future status by positioning themselves in relation to their colleagues through social comparisons. This chapter particularly focuses on the latter topic and develops a conceptual model outlining the motivational and emotional coˇnsequences as well as antecedents that link social comparison processes in meetings to intergenerational learning outcomes of participants from different age groups.

This paper aims to initiate a new, formal theory of sociocultural physics.

Its intended scope is limited to predicting either long‐term, large‐scale or short‐term, small‐scale sociocultural events. The theory that the authors develop, called sociohistory, links three independent but relatable approaches: part of Sorokin's epistemological theory of sociocultural dynamics, Frieden's epistemological theory of extreme physical information (EPI), and Yolles's social viable systems (SVS) theory.

Although not all of Sorokin's ideas are universally accepted, a subset of them is found to be extremely useful for describing the conceptual context of complex systems. This includes how sociocultural processes link closely into political processes.

The theory that develops helps explain how opposing, cultural enantiomers or yin‐yang forces (represented, for instance, by the polar mindsets represented in Islamic fundamentalism and global enterprise) can result in violent conflict, or in either viable or non‐viable social communities. The informations I and J of EPI theory are regarded, respectively, as sensate and ideational enantiomers.

While the resulting sociocultural physics is in its infancy, an illustrative application to the developmental dynamics of post‐colonial Iran demonstrates its potential utility.

In 2017, global plastic production reached 348 million tonnes. Despite growing concerns about the environmental challenges associated with both plastic production and plastic waste, recent estimates suggest that plastic production and subsequent waste is expected to double by the year 2035 (European Commission, 2018). To help reduce the amount of plastic waste that litters the oceans and damages the environment, the European Union has recently commissioned a study about the feasibility of levying a tax on plastic products (New Economic Foundation for the Rethink Plastic Alliance, 2018). However, very few academic articles currently exist that critically examine the arguments for or against a plastic tax and thereby enlighten government and regulators on the subject. This chapter investigates whether plastic taxes can be used as an economic disincentive for plastic products and explores its advantages and disadvantages within a circular economy. It explores whether a plastic tax is the right economic instrument to limit the use of plastics, generate design and technical innovations for bio-based materials and degradable/recyclable plastics, create other economic incentives to optimize the value of plastic and its waste collection, and increase public awareness and responsibility. We find that a plastic tax may be a suitable solution as it is likely to influence the design, production, consumption, and waste sectors if designed properly. Yet, the tax should be carefully implemented and combined with other instruments to obtain the desired outcomes and reduce the occurrence of unfavorable side effects.

This article focuses on Brazil’s migration to digital television. It shows how, in the case of Brazil, unicasting solely reflected the interests of commercial broadcasters. Comparing Brazil to France and the United Kingdom, it explains why the European choice for multicasting is one of the reasons for the success of digital television penetration in these two countries.

By analyzing viewing shares and the financial relevance of the public broadcasters, BBC, and France Televisions, to the national broadcasting spaces, the study concludes that these European traditional broadcasters profited from digital television, despite their exposure to a more competitive environment.

As I will discuss, the model chosen in Brazil continues to hamper Public Service Broadcasting (PSB) and national audiovisual industries’ developments, as well as slowing digital take-up. In Brazil, public broadcasting continued to play a marginal role in the national broadcasting space and the audiovisual market, concentrated in a few local companies.

The findings of this comparative study, developed from a political economy perspective, provide important insights into both Brazilian and European telecommunications policy.

This research examines the effect of auditors’ personal debt on their audit decision making. We developed two different background scenarios that vary the level of the auditor’s personal debt. While one scenario indicated that the partner lived a modest lifestyle and was relatively free of debt, the other indicated that the partner lived an expensive lifestyle and had considerable personal debt. Our data indicate that auditors receiving the higher personal indebtedness scenario were more likely to believe that the auditor in the case study would sign-off on the audit without doing any additional work. We also found that the propensity to believe that the auditor in the case study would sign-off on the audit without doing any additional work decreased as the participants’ rank within the firm increased. Our research documents that a partner’s level of indebtedness could influence the participant’s audit decisions.

Purpose: We review theory and research to suggest how research on sexual and gender minority (SGM) population health could more completely account for social class.

Approach: First, we review theory on social class, gender, and sexuality, especially pertaining to health. Next, we review research on social class among SGM populations. Then, we review 42 studies of SGM population health that accounted for one or more components of social class. Finally, we suggest future directions for investigating social class as a fundamental driver of SGM health.

Findings: Social class and SGM stigma are both theorized as “fundamental causes” of health, yet most studies of SGM health do not rigorously theorize social class. A few studies control socioeconomic characteristics as mediators of SGM health disparities, but that approach obscures class disparities within SGM populations. Only two of 42 studies we reviewed examined SGM population health at the intersections of social class, gender, and sexuality.

Research implications: Researchers interested in SGM population health would benefit from explicitly stating their chosen theory and operationalization of social class. Techniques such as splitting samples by social class and statistical interactions can help illuminate how social class and SGM status intertwine to influence health.

Originality: We synthesize theory and research on social class, sexuality, and gender pertaining to health. In doing so, we hope to help future research more thoroughly account for social class as a factor shaping the lives and health of SGM people.

Concorde AIDS data is used by British Airways for Performance Trend Monitoring, engine control law verification and Low Cycle Fatigue life usage sampling. This paper outlines the requirements for these monitors with reference to the special needs of the Concorde powerplant, together with the content of the Rolls‐Royce computer programmes. The British Airways data acquisition, extraction and verification systems are also covered, together with the use of outputs within the airline organisation.

To measure adolescent girls’ preferences over features of human papillomavirus (HPV) vaccines in order to provide quantitative estimates of the perceived benefits of vaccination and potential vaccine uptake.

A discrete choice experiment (DCE) survey was developed to measure adolescent girls’ preferences over features of HPV vaccines. The survey was fielded to a U.S. sample of 307 girls aged 13–17 years who had not yet received an HPV vaccine in June 2008.

In a latent class logit model, two distinct groups were identified – one with strong preferences against vaccination which largely did not differentiate between vaccine features, and another that was receptive to vaccination and had well-defined preferences over vaccine features. Based on the mean estimates over the entire sample, we estimate that girls’ valuation of bivalent and quadrivalent HPV vaccines ranged between $400 and $460 in 2008, measured as willingness-to-pay (WTP). The additional value of genital warts protection was $145, although cervical cancer efficacy was the most preferred feature. We estimate maximum uptake of 54–65%, close to the 53% reported for one dose in 2011 surveillance data, but higher than the 35% for three doses in surveillance data.

We conclude that adolescent girls do form clear opinions and some place significant value on HPV vaccination, making research on their preferences vital to understanding the determinants of HPV vaccine demand.

DCE studies may be used to design more effective vaccine-promotion programs and for reassessing public health recommendations and guidelines as new vaccines are made available.
