The study's purpose is to investigate the price volatility of four dairy commodities (skim milk powder [SMP], whole milk powder [WMP], butter and cheddar cheese) in the three most significant regional markets (EU, Oceania and US) in the international dairy market.

The study uses a panel-Generalized Autoregressive Conditional Heteroskedastic (panel-GARCH) modeling technique and data from January 12, 2001, to April 28, 2017.

Conditional volatility was higher during subperiods 2007–2010 and 2014–2016 when conditional cross-correlations between prices had the lowest values. In some cases, they were negative (i.e. between the EU and the USA and between Oceania and the USA for both butter and cheese). Interdependence across the three dairy markets, especially for SMP and WMP markets and for the butter market between EU and Oceania is also strongly evidenced. Interdependence is responsible for the spillover of price shocks across the three regions.

The data set used should be extended to cover the COVID-19 pandemic period.

This is the first study to use panel-GARCH to examine international dairy prices and volatility linkages, where previous studies mainly used multivariate GARCH models. Panel-GARCH allows a high-dimensional data series (i.e. 12 dairy prices) and generates potential efficiency gains in estimating conditional variances and covariances by incorporating information about heterogeneity across markets and considering their interdependence.

The authors propose a dairy bundle, integrating strategies to jointly maximise producer revenue and consumer utility according to the latter's preferences.

An algorithm based on a nested logit model identifies the bundle maximising producer revenue based on factors affecting consumer purchase behaviour. The data are drawn from a mall-intercept survey administered in Iran, with consumers stating a hypothetical choice among a comprehensive set of dairy products.

Demographic characteristics and marketing mix elements significantly affect consumers' preferences. An algorithm based on the estimated dissimilarity parameter determines the best bundle of dairy products, simultaneously obtaining the highest utility and the highest expected revenue.

Consumer preference and maximum producer or retail seller income are considered simultaneously. The bundling promotion strategy is widely used for food offerings and fresh foods and can be extended to other products.

我們擬根據消費者偏好，提出一個整合了多個策略的捆綁包，以使生產製作者得到最高的收入和最佳的消費者效用。

研究人員根據巢式Logit 模型的演算法確認了一個捆綁包，以使生產製作者能得到最高的收入，而這均建基於會影響消費者購買行為的各個因素。有關的數據取自於伊朗的商場內進行的攔截調查，而回應的消費者須假想他們從一整套乳製品中選擇他們會購買的產品。

研究結果顯示，人口特徵和市場營銷組合元素均會顯著地影響消費者的偏好，一個基於估算的相異性參數而建立的演算法可確認最佳的乳製品捆綁包，這演算法同時也可取得最佳的裨益和最高的預期收入。

於本研究中，研究人員同時考慮消費者的偏好和生產製作者或零售賣家的最高收入。捆綁式的促銷策略在食物供品和新鮮食品方面被廣泛使用，這策略可擴展至其他產品。

Homelessness has many causes and also is stigmatized in the United States, leading to much misunderstanding of its causes and what policy solutions may ameliorate the problem. The problem is of course getting worse and impacting many communities far removed from the West Coast cities the authors examine in this study. This analysis examines the socioeconomic variables influencing homelessness on the West Coast in recent years. The authors utilize a panel fixed effects model that explicitly includes measures of healthcare access and availability to account for the additional health risks faced by individuals who lack shelter. The authors estimate a spatial error model (SEM) in order to better understand the impacts that systemic shocks, such as the COVID-19 pandemic, have on a variety of factors that directly influence productivity and other measures of welfare such as income inequality, housing supply, healthcare investment, and homelessness.

This chapter critically reviews the literature on authentic leadership (AL) that emerged in response to scandals in private- and public-sector organisations, drawing on theories, concepts and methods from other disciplines. The author finds that AL lacks a consensus definition, and that quantitative research has largely been at the level of employees rather than executives or board members. The review reveals 12 categories of criticisms. Schaefler advocates inductive qualitative research on the major concerns of executive leaders and means of addressing them via group dynamics, maintaining that exploring processes of AL in real-world settings would complement existing quantitative research and contribute to the development and extension of AL theory.

Businesses have increasingly been urged to shift their emphasis away from a purely profit-driven economic perspective to a more sustainable approach to growth that holistically captures people, the planet and profits. Indigenous businesses are well suited to creatively integrate sustainability principles within their internal culture. This enables them to cope with the dominance created by non-indigenous enterprises while also promoting long-term business success. The Triple Bottom Line (TBL) concept has been applied to explore how indigenous businesses in Uganda manifest their best practices by incorporating sustainability principles for lasting economic performance. A multiple case study approach was adopted, and three well-established female-owned indigenous businesses were investigated using in-depth interviews. Integrating sustainability in the business is a fulfiling process if done holistically by embracing a range of interdependent variables that include environmental, social and economic dimensions. The author contributes an innovative culturally sensitive sustainability scope that reflects practical insights on how internal sustainability efforts can be streamlined for long-term economic prosperity without compromising the wider social and physical environment.

Online, distance, and eLearning (ODeL) continue to gain recognition as a mandatory component of delivery of education in institutions of higher learning (IHL) around the world following the outbreak of coronavirus disease (COVID-19). This paradigm shift is informed by the need to ensure uninterrupted, valuable, and safe learning experiences for learners during the pandemic. However, governments ordered the closure of schools and colleges following the declaration of COVID-19 as a world pandemic by the World Health Organization (WHO). A report by United Nations Educational, Scientific and Cultural Organization revealed that there was a significant loss of schooling time following the closure of educational facilities which affected over 1.5 billion learners in 194 nations globally. This study explored the use of online approaches to intensify online learning efficacy in IHL. Data collection was conducted using qualitative methods and data analysis done using themes and sub-themes. Findings from this study indicate that students’ engagements on discussion forums are consistent with collaborative learning. Results further support the view that regular, prompt, and meaningful feedback is critical in promoting constructive learning and reflection among students. Based on the findings of this study, practical implications are discussed for stakeholders interested in establishing and strengthening effective delivery of online learning content to enhance students’ learning experiences.

Food marketing has long been recognized to influence food preferences, consumption and health, yet little is known about the nature and extent of food marketing to young adults – especially with respect to their real-world encounters with food marketing and the appeals they find persuasive. This study aims to engage young adults to explore the persuasive power of food marketing and its platforms of exposure.

Participatory research with 45 young adults, who used a specially designed mobile app to capture the food marketing they encountered for seven days, including information on brand, product, platform and “power” (i.e. the specific techniques that made the advertisement persuasive).

A total of 618 ads were captured for analysis. Results revealed the dominance of digital platforms (especially Instagram, comprising 43% of ads), fast food and beverage brands (48% of ads) and the top persuasive techniques of visual style, special offer and theme.

This study uniquely draws from framing theory to advance the notions of selection and salience to understand food marketing power. It is the first study of its kind to provide a comprehensive look at the platforms and persuasive techniques of food marketing to adults as selected, captured and tagged by participants. It provides timely insights into young adults and food marketing to adults, including where it is encountered, the (generally unhealthy) brands and products promoted and how it is made meaningful.

The objective of this chapter is to discuss how different techniques in Regional Science and Peace Science and the emerging techniques in Management Science can be used in analysing Disaster Management and Global pandemic with special reference to developing countries. It is necessary for me to first discuss the subjects of Disaster Management, Regional Science, Peace Science and Management Science. The objective of this chapter is to emphasise that the studies of Disaster Management should be more integrated with socioeconomic and geographical factors. The greatest disaster facing the world is the possibility of war, particularly nuclear war, and the preparation of the means of destruction through military spending.
