A manual for those working with addicted populations (from lay counsellors to psychiatrists) for delivering the evidence-based Recovery Resilience Program (RRP). RRP is a person-centered, strength and resiliency-based relapse prevention and recovery-oriented intervention that works in synergy with other models, especially 12-Step programs. Presenting practices that enhance 'recovery resilience' – an individual's capacity to effectively apply coping and self-regulation skills in dealing with cravings, triggers, stress, and high-risk situations without reverting to substance use. The program helps individuals to enhance and use their recovery capital at any stage of recovery, and ultimately reach recovery and life goals. It effortlessly integrates with other evidence-based relapse programs, from the original cognitive-behavioral approaches to the newer mindfulness-based and metacognitive approaches. Written by clinicians who have worked with addicts and their families for many decades, the program is easy-to-implement and very little preparation is necessary with handouts and PowerPoints included in each session.
Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group.
Methods
T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9).
Results
PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges’ g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges’ g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (pcorrected = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (pcorrected = .001).
Conclusions
PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.
The macro-social and environmental conditions in which people live, such as the level of a country’s development or inequality, are associated with brain-related disorders. However, the relationship between these systemic environmental factors and the brain remains unclear. We aimed to determine the association between the level of development and inequality of a country and the brain structure of healthy adults.
Methods
We conducted a cross-sectional study pooling brain imaging (T1-based) data from 145 magnetic resonance imaging (MRI) studies in 7,962 healthy adults (4,110 women) in 29 different countries. We used a meta-regression approach to relate the brain structure to the country’s level of development and inequality.
Results
Higher human development was consistently associated with larger hippocampi and more expanded global cortical surface area, particularly in frontal areas. Increased inequality was most consistently associated with smaller hippocampal volume and thinner cortical thickness across the brain.
Conclusions
Our results suggest that the macro-economic conditions of a country are reflected in its inhabitants’ brains and may explain the different incidence of brain disorders across the world. The observed variability of brain structure in health across countries should be considered when developing tools in the field of personalized or precision medicine that are intended to be used across the world.
The tomato leafminer, Phthorimaea absoluta (synonym Tuta absoluta Meyrick, 1917), is a transboundary plant pest that poses a serious threat to global tomato cultivation and production, with significant negative social and environmental impact from increased insecticide usage for its management. We present three P. absoluta draft mitochondrial genomes (mitogenomes) from Malawi and South Africa, thereby increasing the mitogenome resources for this invasive agricultural pest. Comparative analysis with Spain, China, and Kenya samples revealed at least seven maternal lineages across its current invasive ranges, supporting multiple introductions as a major factor for the spread of invasive populations. Mitogenome results therefore identified unexpected diversity as compared to the use of the partial mitochondrial cytochrome oxidase subunit I (mtCOI/cox1) gene marker for the inference of P. absoluta invasion biology. The whole-genome sequencing approach further identified alternative mitochondrial DNA (mtDNA) gene regions necessary to improve diversity estimates, and enables concurrent characterisation of insecticide resistance genes. Characterisation of the VSSG (Para) and AChE-1/ace-1 gene profiles that underpin pyrethroid and organophosphate (OP) resistances, respectively, confirmed co-introductions of pyrethroid and OP resistance genes into Malawian and South African populations. Our study highlights the need for additional P. absoluta mitogenome resources, especially from native populations that is needed for more accurate interpretations of introduction pathways and the development of future sustainable management strategies.
Corporate governance plays a key role in ensuring that companies act responsibly and legally in the pursuit of long-term, sustainable growth. Now in its fifth edition, Principles of Contemporary Corporate Governance offers a comprehensive introduction to the rules and regulations of corporate governance systems. It takes an inclusive stakeholder approach to examine how companies apply corporate governance principles in the private sector. The four-part structure has been consolidated and streamlined to provide logical coverage of fundamental contemporary themes and issues. The text has been updated to include new case studies and discussion of recent developments, such as the impact of the Covid-19 pandemic and the destruction of a sacred rock shelter at Juukan Gorge. A new section on corporate governance in Singapore offers insight into corporate governance internationally. Written by an expert author team, Principles of Contemporary Corporate Governance remains an indispensable resource for business and law students studying corporate governance.
As touched upon in Chapter 1, contemporary commentary on corporate governance can be divided into two main approaches: stakeholder primacy, and the narrower shareholder primacy. This chapter focuses on the first of these objectives. We commence the chapter by pointing out that an approach that accentuates the differences between a shareholder versus a stakeholder theory of the corporation is probably a contradiction and a false dichotomy. We then deal with the important aspect of corporate social responsibility (‘CSR’) and the related issue of disclosure of and reporting on non-financial matters. As part of this discussion we focus on the controversial and highly topical issue of companies exaggerating their image as environmentally friendly corporations (greenwashing) to please investors and to attract more investments, as well as smartening their image on other issues (greenscreening). This chapter then looks at the ‘social licence to operate’ before shifting to CSR and directors’ duties. The chapter concludes by considering the meaning of ‘stakeholders’ and how all corporate stakeholders have vested interests in the sustainability of corporations.
This chapter opens with a brief discussion of the nature of business ethics, its significance for corporations and the ethical dimensions of a corporation’s stakeholder relationships. The next section is focused on the causes of ethical problems: bad apples, bad cases and bad barrels. In order to examine these it presents the theory related to each before drawing on three case studies: the HIH failure, the LIBOR case and the destruction of Juukan Gorge. The extent to which we attempt to encourage ethical conduct is discussed in the following section. In particular, that section examines corporate accountability, individual accountability and organisation-level approaches that seek to shape the ethical conduct of corporations. The final section is devoted to some concluding remarks.
Since at least 2018 there has been a major shift within ‘Business America’ away from ‘shareholder capitalism’ towards ‘stakeholder capitalism’, a move which has already had some global impact. Our approach is, however, realistic and we also make the reader aware of the challenges for countries, particularly where shareholder primacy is deeply embedded in statutory law and case law, to move from shareholder primacy to an all-inclusive stakeholder model of corporate law and corporate governance. In this chapter we extract some of the ‘essential’ principles of corporate governance and illustrate that there is a ‘business case’ for good corporate governance. We conclude the chapter by discussing broader trends and debates with a present and likely future impact on corporate governance. These include what can be described as the ‘Fourth Industrial Revolution’; the widening gap between the ‘rich’ and the ‘poor’, or, put differently, ‘the price of inequality’; the growing problem regarding profit-sharing or capital distribution in large public corporations; and a short discussion of the so-called ‘Great Reset’.
Historically, the power to manage the business of all companies and corporations was conferred upon the board of directors. The fact that it was impossible for a board of directors to manage the day-to-day business of large public corporations was only openly acknowledged in the past three decades. This chapter focuses on the organs of a company and then discusses the main functions of a board of directors. It is clear that there is an important distinction between managing the business of the company and directing, supervising and overseeing the management of the business of corporations in large public companies. The board is responsible for directing, supervising and overseeing the management of the business of corporations. Managing the business of large public corporations is normally left to management, but under control of the board.
As a general rule, directors owe their duties to the company as a whole, not to individual shareholders. Historically, directors’ duties and liability were discussed under general law duties (duties at common law or in equity); subsequently, they were added to under statutory duties. Under general law duties, most courts and commentators usually draw a distinction between equitable duties based on loyalty and good faith, with a particular focus on fiduciary duties, and the duty to act with due care and diligence (the duty of care). The duty of care may arise under principles of equity and at common law, in both contract and tort. Fiduciary duties in Australian law are proscriptive, not prescriptive. That is, the duties prohibit the fiduciary from engaging in particular conduct rather than prescribing what the fiduciary must do in particular situations. The failure to act in a reasonable manner has traditionally fallen within the domain of the duty of care, whereas behavior which falls foul of principles of loyalty is addressed more clearly in equity.
In this chapter we establish the foundations for extracting principles of contemporary corporate governance. We begin the chapter by providing our own definition of the term ‘corporate governance’. The reason for this is to enable the reader to gain a good understanding of how we approach the principles of contemporary corporate governance in this book. We have adjusted the definition of corporate governance in each of the previous four editions, as well as in this edition. The reason is that corporate governance is a dynamic concept and we strive to keep the definition updated to reflect contemporary principles of corporate governance.
In the previous chapter we saw that modern community expectations require that all types of directors fulfil their duties of care and diligence meticulously. No longer may directors hide behind ignorance or inaction; nor are the duties of non-executive directors seen as being of an intermittent nature. All directors have a positive duty to challenge, inquire and investigate when controversial or potentially risky matters are discussed at board level. In this chapter we see that there are various types of company directors and officers, although the basic position is that the law will expect the same duties of all directors and that senior employees and senior executives owe duties to the company comparable to those of directors.
It will be clear from Chapter 4 that we consider regulation of corporate governance to be prominent in a good corporate governance model. This chapter builds upon that model by focusing on the regulation of corporate governance in particular. It deals specifically with the various mechanisms, legislative and non-legislative, which regulate the corporation and which set in place, collectively, a framework by which good governance can be achieved. Overall, this collective body of mechanisms forms part of what has recently been described as an emerging ‘law of corporate governance’. The regulation of corporate governance in Australia is achieved through binding and non-binding rules, international recommendations and industry-specific standards, the commentaries of scholars and practitioners, and the decisions of judges. The legislature acts to facilitate the achievement of good corporate governance directly by refining corporate law, and indirectly through the entire panoply of rules and regulations which have an impact on the corporation and its activities. There are other agencies that also assume a role in the regulation of corporate governance.
Australia has a long tradition of shareholder activism. What has changed in recent years is the nature of the shareholders who are taking activist positions. Institutional investors have always exercised some measure of influence over the management of large public corporations, but recent developments in shareholder activism have brought these manoeuvres into the public spotlight. Australia’s corporate landscape has featured a range of high-profile boardroom battles with activist investors. This chapter explores the nature and scope of shareholder activism in Australia (including reference to international developments) and its implications for corporate governance.
