Stress-Induced Reinstatement of Drug Seeking: 20 Years of Progress

In human addicts, drug relapse and craving are often provoked by stress. Since 1995, this clinical scenario has been studied using a rat model of stress-induced reinstatement of drug seeking. Here, we first discuss the generality of stress-induced reinstatement to different drugs of abuse, different stressors, and different behavioral procedures. We also discuss neuropharmacological mechanisms, and brain areas and circuits controlling stress-induced reinstatement of drug seeking. We conclude by discussing results from translational human laboratory studies and clinical trials that were inspired by results from rat studies on stress-induced reinstatement. Our main conclusions are (1) The phenomenon of stress-induced reinstatement, first shown with an intermittent footshock stressor in rats trained to self-administer heroin, generalizes to other abused drugs, including cocaine, methamphetamine, nicotine, and alcohol, and is also observed in the conditioned place preference model in rats and mice. This phenomenon, however, is stressor specific and not all stressors induce reinstatement of drug seeking. (2) Neuropharmacological studies indicate the involvement of corticotropin-releasing factor (CRF), noradrenaline, dopamine, glutamate, kappa/dynorphin, and several other peptide and neurotransmitter systems in stress-induced reinstatement. Neuropharmacology and circuitry studies indicate the involvement of CRF and noradrenaline transmission in bed nucleus of stria terminalis and central amygdala, and dopamine, CRF, kappa/dynorphin, and glutamate transmission in other components of the mesocorticolimbic dopamine system (ventral tegmental area, medial prefrontal cortex, orbitofrontal cortex, and nucleus accumbens). (3) Translational human laboratory studies and a recent clinical trial study show the efficacy of alpha-2 adrenoceptor agonists in decreasing stress-induced drug craving and stress-induced initial heroin lapse

Environmental Citizenship in Primary Formal Education

The concept of Environmental Citizenship, as it has been developed in this project, calls for the development of specific awareness, attitudes, skills, behaviours and competences that need to be cultivated from early childhood for active civic participation. Primary formal education could provide opportunities for the achievement of these goals. In this chapter, we elaborate on how Environmental Citizenship, which provides the specifics of age and formal settings, could be approached and the educational strategies that could be recommended or avoided based on the existing literature. This chapter also provides an overview of the most important educational aims regarding the development of Environmental Citizenship in primary formal education. These include environmental sensitivity, a sense of justice, a basic understanding of ecological systems, necessary skills for the investigation of ecological and social phenomena, and action skills that relate to active participation in community issues. We suggest that successful educational interventions, integrated pedagogical approaches and key designing principles could promote Environmental Citizenship at primary schools. In addition, effective training and professional development programmes can equip teachers with the knowledge, values, skills and strategies necessary to implement Environmental Citizenship at this level

A qualitative investigation of lived experiences of long-term health condition management with people who are food insecure.

Background: As more people are living with one or more chronic health conditions, supporting patients to become activated, self-managers of their conditions has become a key health policy focus both in the UK and internationally. There is also growing evidence in the UK that those with long term health conditions have an increased risk of being food insecure. While international evidence indicates that food insecurity adversely affects individual's health condition management capability, little is known about how those so affected manage their condition(s) in this context. An investigation of lived experience of health condition management was undertaken with food insecure people living in north east Scotland. The study aimed to explore the challenges facing food insecure people in terms of, i. their self-care condition management practices, and ii. disclosing and discussing the experience of managing their condition with a health care professional, and iii. Notions of the support they might wish to receive from them. Methods: Twenty in-depth interviews were conducted with individuals attending a food bank and food pantry in north east Scotland. Interview audio recordings were fully transcribed and thematically analysed. Results: Individuals reporting multiple physical and mental health conditions, took part in the study. Four main themes were identified i.e.: 1. food practices, trade-offs and compromises, that relate to economic constraints and lack of choice; 2. illness experiences and food as they relate to physical and mental ill-health; 3. (in) visibility of participants' economic vulnerability within health care consultations; and 4. perceptions and expectations of the health care system. Conclusions: This study, the first of its kind in the UK, indicated that participants' health condition management aspirations were undermined by the experience of food insecurity, and that their health care consultations in were, on the whole, devoid of discussions of those challenges. As such, the study indicated practical and ethical implications for health care policy, practice and research associated with the risk of intervention-generated health inequalities that were suggested by this study. Better understanding is needed about the impact of household food insecurity on existing ill health, wellbeing and health care use across the UK

What Difference Does a Visit Make? Changes in Animal Welfare Perceptions after Interested Citizens Tour a Dairy Farm

Citizens’ concerns about farm animal welfare are often dismissed on the assumption that they are not well informed about farming practices. We conducted exploratory surveys of interested citizens (n = 50) before and after a self-guided tour of a 500-head dairy farm. ‘Before’ survey questions explored perceptions, concerns, and values about dairy cattle farming and welfare, in addition to a short knowledge-based quiz on dairy cattle husbandry. An ‘after’ survey explored the extent to which these constructs shifted after the tour. Before, most participants correctly answered quiz questions about general feeding and housing practices, but scores were low on questions about specific practices such as cow-calf separation. Participants considered several elements as necessary for a ‘good’ life for dairy cattle: fresh food and water, pasture access, gentle handling, space, shelter, hygiene, fresh air and sunshine, social companions, absence of stress, health, and safety from predators. These elements reflect a diverse conception of animal welfare that incorporates values for physical and mental well-being, natural living, and humane care. The visit had a mixed effect on perceptions of whether dairy cows had a ‘good’ life, improving perceptions for a quarter of participants, worsening perceptions in a third, with no shift in the remaining participants. The visit appeared to mitigate some concerns (e.g., provision of adequate food and water, gentle humane care) while reinforcing or eliciting others (e.g., lack of pasture access, early cow-calf separation). Moreover, animal welfare-relevant values held by participants (e.g., natural living, care) appeared to play an important role in influencing perceptions of farm practices. These results suggest that education and exposure to livestock farming may resolve certain concerns, but other concerns will likely persist, especially when practices conflict with deeply held values around animal care

Anticipation in entrepreneurship

Entrepreneurship is a forward looking activity that embodies implicit imaginaries. If we remove the notion of a future from the field of entrepreneurship, field would cease to exist as its whole rationale is prospective. Entrepreneurship creates future value (Schumpeter 1934) through creative destruction; in uncertain contexts (Knight 1923) and with ‘alertness’ to opportunity (Kirzner 1982). Entrepreneurial opportunity em-braces anticipation as imaginative reason, strategically employed and motivated by aspiration. Entrepreneurial effectuation is concerned with the controllable aspects of an unpredictable future. Entrepreneuring is a process (Steyaert 2007) producing ontological emergence. Entrepreneurship is expressed in action and produces change. Nadin observes that anticipation relates to the perception of change (Nadin 2010) and is always expressed in action (Nadin 2015). Entrepreneurial identity is sig-nificant and the models embodied in an anticipatory system are what comprise its individuality; what distinguish it uniquely from other sys-tems. A change in these models is a change of identity (Rosen et al. 2012, p370). Entrepreneurship is relational and is coupled with other ac-tors in the environment, generating a sense of shared anticipation, or anticipatory coupling. Anticipatory coupling as a social phenomenon seems ripe for further research. Being emplaced, entrepreneuring practice involve sensing and anticipation (Antonacopoulou and Fuller 2019). Although anticipation is a natural activity, the effectiveness of anticipation can be improved through greater awareness in each of these sets of processes, among others. We suggest that the dynamics of emergence require anticipations of multiple forms of value. Seeing entrepreneurship from an anticipatory standpoint brings more to the fore the nature of values in practice. Further research can help reveal the anticipatory work is done in entrepreneurship to maintain the anticipatory capacity of the enterprise and of the interdependent relationships that maintain the enterprise
