Cultural and economic complementarities of spatial agglomeration in the British television broadcasting industry: Some explorations.

This paper considers the processes supporting agglomeration in the British television broadcasting industry. It compares and contrasts the insights offered by the cultural turn in geography and more conventionally economic approaches. It finds that culture and institutions are fundamental to the constitution of production and exchange relationships and also that they solve fundamental economic problems of coordinating resources under conditions of uncertainty and limited information. Processes at a range of spatial scales are important, from highly local to global, and conventional economics casts some light on which firms are most active and successful

Regional integration, multinational enterprise strategy and the impact of country-level risk: the case of the EMU

The European Monetary Union (EMU) provides a new macro-level, institutional setting for multinational enterprises (MNEs). The authors investigate the impact of regional integration on MNE strategy by analysing Belgian firms’ entry-mode choices in foreign markets, both EMUand non-EMU ones, with a focus on what impact remains of countrylevel risk. They demonstrate that regional integration has altered the impact of countrylevel institutional risk on MNE entry-mode choices inside the EMU. The conventional predictions of international business theory have been reversed, with higher country-level risk inside the EMU driving a preference for wholly owned subsidiaries.Within the integrated region, insider firms now view higher country-level risk as the equivalent of higher, micro-level contracting risk. Such risk can best be mitigated through full internalization, combined with arm’s length contracts, rather than through equity joint ventures

Engagement With a Behavior Change App for Alcohol Reduction: Data Visualization for Longitudinal Observational Study

BACKGROUND: Behavior change apps can develop iteratively, where the app evolves into a complex, dynamic, or personalized intervention through cycles of research, development, and implementation. Understanding how existing users engage with an app (eg, frequency, amount, depth, and duration of use) can help guide further incremental improvements. We aim to explore how simple visualizations can provide a good understanding of temporal patterns of engagement, as usage data are often longitudinal and rich. OBJECTIVE: This study aims to visualize behavioral engagement with Drink Less, a behavior change app to help reduce hazardous and harmful alcohol consumption in the general adult population of the United Kingdom. METHODS: We explored behavioral engagement among 19,233 existing users of Drink Less. Users were included in the sample if they were from the United Kingdom; were 18 years or older; were interested in reducing their alcohol consumption; had a baseline Alcohol Use Disorders Identification Test score of 8 or above, indicative of excessive drinking; and had downloaded the app between May 17, 2017, and January 22, 2019 (615 days). Measures of when sessions begin, length of sessions, time to disengagement, and patterns of use were visualized with heat maps, timeline plots, k-modes clustering analyses, and Kaplan-Meier plots. RESULTS: The daily 11 AM notification is strongly associated with a change in engagement in the following hour; reduction in behavioral engagement over time, with 50.00% (9617/19,233) of users disengaging (defined as no use for 7 or more consecutive days) 22 days after download; identification of 3 distinct trajectories of use, namely engagers (4651/19,233, 24.18% of users), slow disengagers (3679/19,233, 19.13% of users), and fast disengagers (10,903/19,233, 56.68% of users); and limited depth of engagement with 85.076% (7,095,348/8,340,005) of screen views occurring within the Self-monitoring and Feedback module. In addition, a peak of both frequency and amount of time spent per session was observed in the evenings. CONCLUSIONS: Visualizations play an important role in understanding engagement with behavior change apps. Here, we discuss how simple visualizations helped identify important patterns of engagement with Drink Less. Our visualizations of behavioral engagement suggest that the daily notification substantially impacts engagement. Furthermore, the visualizations suggest that a fixed notification policy can be effective for maintaining engagement for some users but ineffective for others. We conclude that optimizing the notification policy to target both effectiveness and engagement is a worthwhile investment. Our future goal is to both understand the causal effect of the notification on engagement and further optimize the notification policy within Drink Less by tailoring to contextual circumstances of individuals over time. Such tailoring will be informed from the findings of our micro-randomized trial (MRT), and these visualizations were useful in both gaining a better understanding of engagement and designing the MRT

Consumers on critique: a survey of classical music listeners’ engagement with professional music reviews

Music criticism has a long tradition as a leading agent in the classical music discourse. However, some people question its function in the contemporary music market. We explored the topicality of classical music critique by asking: Who reads professional reviews today? And what do readers expect from review? Through an online survey (English/German), we profiled the listening habits of classical music listeners (N = 1200) and their engagement with professional reviews. Our participants were more actively engaged with music, but contrary to the ‘highbrow’ stereotype, not more highly musically trained than the general population. They consumed music and opinion sources in a variety of ways. Approximately two-thirds (n = 741) of the participants had recently engaged with professional reviews, which were perceived as the most useful form of opinion, followed by short written commentaries and, lastly, ratings. A multiple logistic regression model suggested that the typical consumer of professional music critique was older with higher levels of musical engagement and education, had a higher inclination to purchase music and lower usage of streaming services, and had a preference for detailed reviews from traditional sources (e.g. newspapers). According to review readers, reviews should cover a variety of topics and offer evaluations underpinned with reasons. Reviewers should be constructive, open-minded, respectful, and well informed; their professional background was less relevant. Professional reviews should not necessarily provide a recommendation on what to buy, but rather guide listeners’ musical appreciation and understanding. Professional criticism still has an audience, although more so among older, musically educated listeners. Critics need to explore various channels in order to connect to a new generation of classical music listeners

Commissioning of the electron injector for the AWAKE experiment

The advanced wakefield experiment (AWAKE) at CERN is the first proton beam-driven plasma wakefield acceleration experiment. The main goal of AWAKE RUN 1 was to demonstrate seeded self-modulation (SSM) of the proton beam and electron witness beam acceleration in the plasma wakefield. For the AWAKE experiment, a 10-meter-long Rubidium-vapor cell together with a high-power laser for ionization was used to generate the plasma. The plasma wakefield is driven by a 400 GeV/c proton beam extracted from the super proton synchrotron (SPS), which undergoes a seeded self-modulation process in the plasma. The electron witness beam used to probe the wakefields is generated from an S-band RF photo-cathode gun and then accelerated by a booster structure up to energies between 16 and 20 MeV. The first run of the AWAKE experiment revealed that the maximum energy gain after the plasma cell is 2 GeV, and the SSM mechanism of the proton beam was verified. In this paper, we will present the details of the AWAKE electron injector. A comparison of the measured electron beam parameters, such as beam size, energy, and normalized emittance, with the simulation results was performed

The Ethics of Corporate Governance

How should corporate directors determine what is the right decision? For at least the past 30 years the debate has raged as to whether shareholder value should take precedence over corporate social responsibility when crucial decisions arise. Directors face pressure, not least from ethical investors, to do the good thing when they seek to make the right choice. Corporate governance theory has tended to look to agency theory and the need of boards to curb excessive executive power to guide directors' decisions. While useful for those purposes, agency theory provides only limited guidance. Supplementing it with the alternatives - stakeholder theory and stewardship theory - tends to put directors in conflict with their legal obligations to work in the interests of shareholders. This paper seeks to reframe the discussion about corporate governance in terms of the ethical debate between consequential, teleological approaches to ethics and idealist, deontological ones, suggesting that directors are - for good reason - more inclined toward utilitarian judgments like those underpinning shareholder value. But the problems with shareholder value have become so great that a different framework is needed: strategic value, with an emphasis on long-term value creation judged from a decidedly utilitarian standpoint

Vertical monopoly power, profit and risk: The British beer industry, c.1970-2004

By investigating surplus and risk distribution in the British brewing industry, this paper shows that risk and risk transfer are important dimensions of vertical supply chain relationships. A comparative financial analysis shows the effects of models of vertical ownership before and after the break-up of producer controlled tenanted estates and the strategy and performance of pub-owning companies. Contrasting mechanisms for controlling the capture of surplus and division of risk are evaluated. The paper complements prior studies that have concentrated on the brewers by assessing winners and losers amongst pub owning companies and tenants in different models of vertical organisation and how they might be effectively regulated
