Framed by a social exchange perspective, this study address the issue of whether positive employees’ perceptions about human resource management practices influence positive attitudes and behaviour. We hypothesize that human resource management practices (HRMP) have a significant negative effect on intention to voluntary leave the organization and a positive effect on organizational citizenship behaviour (OCB), and that OCB could mediate the relationship between HRMP and turnover intention. A sample of 165 employees from the Portuguese public administration participated in the study. Data was analysed through descriptive statistics, confirmatory factor analysis and hypotheses were tested using single and multiple linear regressions. Results indicate that HRMP is positively associated with OCB, but only internal communication practice is highly valued by Portuguese public employees and successfully predicts OCB. HRMP also show a positive association with turnover intention but only celebration and recognition practices are predictors of turnover intention. Contrary to our hypothesis OCB did not acted as mediator between HRMP and turnover intention. Some suggestions on managerial human resource practices were proposed as well as some main questions raised in the Portuguese public administration context.

Gut microbiota colonization is a key event for host physiology that occurs early in life. Disruption of this process leads to altered brain development which ultimately manifests as changes in brain function and behaviour in adulthood. Studies using germ-free mice highlight the extreme impact on brain health that results from life without commensal microbes, however the impact of microbiota disturbances occurring in adulthood is less studied. To this end, we depleted the gut microbiota of 10-week-old male Sprague Dawley rats via chronic antibiotic treatment. Following this marked, sustained depletion of the gut bacteria, we investigated behavioural and molecular hallmarks of gut-brain communication. Our results reveal that depletion of the gut microbiota during adulthood results in deficits in spatial memory as tested by Morris water maze, increased visceral sensitivity and a greater display of depressive-like behaviours in the forced swim test. In tandem with these clear behavioural alterations we found change in altered CNS serotonin concentration along with changes in the mRNA levels of corticotrophin releasing hormone receptor 1 and glucocorticoid receptor. Additionally, we found changes in the expression of BDNF, a hallmark of altered microbiota-gut-brain axis signaling. In summary, this model of antibiotic-induced depletion of the gut microbiota can be used for future studies interested in the impact of the gut microbiota on host health without the confounding developmental influence of early-life microbial alterations.

Are there variations in behaviours and leadership styles of next-generation family members or descendants who join their family business due to different forms of commitment? Evidence from a dual respondent study of 109 Canadian and Swiss family firms suggests that descendants with affective commitment to their family firms are more likely to engage in discretionary activities going beyond the job description, thereby contributing to organizational performance. Next-generation members with normative commitment are more likely to engage in transformational leadership behaviours. Both affectively and normatively motivated next-generation members use contingent reward forms of leadership. A surprising finding of this study is the binding force of normative commitment on positive leadership behaviours of next-generation members. This study empirically tests the generalizability of the three-component model of commitment to family businesses, a context in which different forms of commitment may play a unique role.

The behavioural agency theory was developed to provide a more comprehensive explanation and prediction of managerial risk taking, in response to some shortcomings of agency theory. In general, the theory offers explanations of why decision makers prefer some strategic choices to others. The use of behavioural agency theory in family business research has, however, been very limited. Family business scholars recently adapted this theory to construct the family business variant, the ‘socioemotional wealth’ construct, which offers better explanations for the risk taking and decision making behaviours of family firms. This chapter provides an overview of behavioural agency theory and the socioemotional wealth construct, explores how they have been used in family business research, and offers suggestions for how this theory can be used in further research to contribute to both the family business and the general management literature. Keywords: family business, behavioural agency theory, socioemotional wealth, family firm heterogeneity.

Fifty years have passed since Cyert and March’s 1963 A Behavioral Theory of the Firm. During this time, BTOF has been adopted across different research domains to investigate how organizations set goals, how they determine aspirations and how they finally react to performance aspiration discrepancies. Cyert and March’s framework has also recently emerged as one of the dominant paradigms to understand the ways in which family business organizations make decisions. In this chapter, I review the theoretical development and empirical results of BTOF and its application in the family business field of study in order to identify theoretical and empirical gaps and propose suggestions for future research. The conclusions suggest that BTOF is both a theoretically and empirically valid perspective in family business research, particularly when combined with other theoretical frameworks. The principal recommendation is to apply behavioral theory to enhance scholarly understanding of how family organisations define their aspiration levels and respond to organizational problems.

In the context of the International Society for Knowledge Organization, we often consider knowledge organization systems to comprise catalogues, thesauri, and bibliothecal classification schemes – schemes for library arrangement. In recent years we have added ontologies and folksonomies to our sphere of study. In all of these cases it seems we are concerned with improving access to information. We want a good system.And much of the literature from the late 19th into the late 20th century took that as their goal – to analyze the world of knowledge and the structures of representing it as its objects of study; again, with the ethos for creating a good system. In most cases this meant we had to be correct in our assertions about the universe of knowledge and the relationships that obtain between its constituent parts. As a result much of the literature of knowledge organization is prescriptive – instructing designers and professionals how to build or use the schemes correctly – that is to maximize redundant success in accessing information.In 2005, there was a turn in some of the knowledge organization literature. It has been called the descriptive turn. This is in relation to the otherwise prescriptive efforts of researchers in KO. And it is the descriptive turn that makes me think of context, languages, and cultures in knowledge organization–the theme of this year’s conference.Work in the descriptive turn questions the basic assumptions about what we want to do when we create, implement, maintain, and evaluate knowledge organization systems. Following on these assumptions researchers have examined a wider range of systems and question the motivations behind system design. Online websites that allow users to curate their own collections are one such addition, for example Pinterest (cf., Feinberg, 2011). However, researchers have also looked back at other lineages of organizing to compare forms and functions. For example, encyclopedias, catalogues raisonnés, archival description, and winter counts designed and used by Native Americans.In this case of online curated collections, Melanie Feinberg has started to examine the craft of curation, as she calls it. In this line of research purpose, voice, and rhetorical stance surface as design considerations. For example, in the case of the Pinterest, users are able and encouraged to create boards. The process of putting together these boards is an act of curation in contemporary terminology. It is describing this craft that comes from the descriptive turn in KO.In the second case, when researchers in the descriptive turn look back at older and varied examples of knowledge organization systems, we are looking for a full inventory of intent and inspiration for future design. Encyclopedias, catalogues raisonnés, archival description, and works of knowledge organization in other cultures provide a rich world for the descriptive turn. And researchers have availed themselves of this.

This paper proposes a dual conception of work in knowledge organization. The first part is a conception of work as liminal, set apart from everyday work. The second is integrated, without separation. This talk is the beginning of a larger project where we will characterize work in knowledge organization, both as it is set out in our literature (Šauperl, 2004; Hjørland 2003 Wilson, 1968), and in a philosophical argument for its fundamental importance in the activities of society (Shera, 1972; Zandonade, 2004).But in order to do this, we will co-opt the conception of liminality from the anthropology of religion (Turner, 1967), and Zen Buddhist conceptions of moral action, intention, and integration (Harvey, 2000 and cf., Harada, S., 2008).The goal for this talk is to identify the acts repeated (form) and the purpose of those acts (intention), in knowledge organization, with specific regard to thresholds (liminal points) of intention present in those acts.We can then ask the questions: Where is intention in knowledge organization liminal and where is it integrated? What are the limits of knowledge organization work when considered at a foundational level of the intention labor practices? Answering such questions, in this context, allows us to reconsider the assumptions we have about knowledge organization work and its increasingly important role in society. As a consequence, we can consider the limits of classification research if we see the foundations of knowledge organization work when we see forms and intentions. I must also say that incorporating Zen Buddhist philosophy into knowledge organization research seems like it fits well with ethics and ethical responses the practice of knowledge organization. This is because 20th Century Western interpretations of Zen are often rooted in ethical considerations. This translates easily to work.

Background : Developmental coordination disorder (DCD) is a prevalent neurodevelopmental disorder. Best practices include raising parents’ awareness and building capacity but few interventions incorporating these best practices are documented. Objective : To examine whether an evidence-based online module can increase the perceived knowledge and skills of parents of children with DCD, and lead to behavioural changes when managing their child’s health condition. Methods : A mixed-methods, before-after-follow-up design guided by the theory of planned behaviour was employed. Data about the knowledge, skills and behaviours of parents of children with DCD were collected using questionnaires prior to completing the module, immediately after, and three months later. One-way repeated measures ANOVAs and thematic analyses were performed on data as appropriate. Results : Fifty-eight participants completed all questionnaires. There was a significant effect of time on self-reported knowledge [F(2.00,114.00)=16.37, p=0.00] and skills [F(1.81,103.03)=51.37, p=0.00] with higher post- and follow-up scores than pre-intervention scores. Thirty-seven (65%) participants reported an intention to change behaviour postintervention; 29 (50%) participants had tried recommended strategies at follow-up. Three themes emerged to describe parents’ behavioural change: sharing information, trialing strategies and changing attitudes. Factors influencing parents’ ability to implement these behavioural changes included clear recommendations, time, and ‘right’ attitude. Perceived outcomes associated with the parental behavioural changes involved improvement in well-being for the children at school, at home, and for the family as a whole. Conclusions : The online module increased parents’ self-reported knowledge and skills in DCD management. Future research should explore its impacts on children’s outcomes long-term.

Introducción: La implicación social dentro de la problemática ambiental, establece una relación causal entre hábitos e impacto ambiental; aspectos del comportamiento humano tales como la conveniencia, familiaridad, presión social y actitud, nos permiten realizar un acercamiento acerca de la decisión de reciclar o no en un hogar. Objetivo: identificar los factores ambientales asociados con el manejo de residuos domésticos entre los miembros de una comunidad residencial en la ciudad de Bogotá. Materiales y métodos: Se realizó un estudio transversal realizado a 200 personas de una comunidad residencial. La evaluación de la conducta pro-ambiental se llevó a cabo por medio de la utilización de la Escala del Comportamiento Pro-ambiental desarrollada por Corral-Verdugo unida a la escala de Reciclaje de Sidique. Para el tratamiento estadístico se empleó el análisis de regresión lineal múltiple. Resultados: La mayoría de los encuestados fueron hombres (55%), con una mediana de edad de 37,5 años. Más de la mitad tenía por lo menos formación en pregrado (53%), el 55,5% contaban con un empleo al momento de la entrevista, cerca del 50% de las personas refirieron tener casa propia y la mediana del tamaño de las mismas fue de 80 m2. De los aspectos sociodemográficos, el tipo de vivienda, sexo y edad, estuvieron relacionados con los factores ambientales pro reciclaje. Mientras que las conductas proambientales relacionadas fueron: altruismo, frugalidad, conducta ecológica general, indignación y aprecio por la naturaleza. Conclusiones: Las conductas proambientales Altruismo, Frugalidad, Conducta Ecológica, Indignación y Aprecio por lo natural, están relacionadas con la intención de reciclar. Para futuras investigaciones es necesario constatar la realización del comportamiento proambiental, para aseverar de manera irrebatible que las dimensiones analizadas pueden soportar una acción real y no un auto reporte de una conducta.

That humans and animals learn from interaction with the environment is a foundational idea underlying nearly all theories of learning and intelligence. Learning that certain outcomes are associated with specific actions or stimuli (both internal and external), is at the very core of the capacity to adapt behaviour to environmental changes. In the present work, appetitive and aversive reinforcement learning paradigms have been used to investigate the fronto-striatal loops and behavioural correlates of adaptive and maladaptive reinforcement learning processes, aiming to a deeper understanding of how cortical and subcortical substrates interacts between them and with other brain systems to support learning. By combining a large variety of neuroscientific approaches, including behavioral and psychophysiological methods, EEG and neuroimaging techniques, these studies aim at clarifying and advancing the knowledge of the neural bases and computational mechanisms of reinforcement learning, both in normal and neurologically impaired population.

Alongside the developments in behavioural economics, the concept of nudge was introduced as an intervention able to guide individual behaviour towards better choices without using coercion or incentives. While behavioural teams were created inside governmental units and regulatory authorities, nudging emerged in regulatory discourse, being increasingly regarded as a regulatory instrument that could overcome the disadvantages of other tools. This thesis analyses the viability of incorporating nudges into regulation. In particular, it investigates the implications for regulators of bringing iterative experimental testing – a widespread nudge design methodology outside regulation – into their own design practices. Nudges outside regulation are routinely designed using experiments of all kinds. This thesis intends to answer whether design premises rooted in iterative experimentation are still valid in the regulatory space, an arena that nudging entered into and that is distinct from the one where it originally emerged. The design and provision of nudges using the premises of iterative experimental testing is possible, but at a cost and burden for regulatory nudge designers. Therefore, the thesis evaluates how this burden can be reduced, in particular how nudges can be feasibly designed and provided through regulation or, put differently, how to more efficiently design and provide nudging as a regulatory tool.

In this thesis, I study the notion of program equivalences, i.e. proving that two programs can be used interchangeably without altering the overall observable behaviour. This definition is highly dependent on the contexts in which these programs can be used; does the context have exceptions, parallelism, etc... So proofs also need to be adapted according to the expressiveness of those contexts. This thesis presents on the pi-calculus – a concurrent programming language – under various typing constraints. Types allows us to impose different disciplines like forcing a sequential execution, or ensuring linearity, meaning an object can be used once. In each case, the bisimulation, a standard proof technique for the pi-calculus, needs to be adapted accordingly to obtain a suitable equivalence. We then test how using the modified bisimulations can be used to reason about a language with higher-order functions and references, which once translated into the pi-calculus satisfies the typing constraints.

SDG 12.3 aims to promote sustainable consumption and production patterns by addressing the global food loss and waste problem. Given the multiple interrelated impacts, food waste is recognized as one of the major food system challenges. The scope of this work is to contribute to the understanding on food waste generation and potential approaches to tackle it. This work was specifically designed to achieve the following goals: 1) Understand specific factors that affect individual behaviours to generate FW at household, 2) Analyse the effective ways to reduce FW through behaviour change perspective given the catering and hospitality sector, and 3) Provide an evidence synthesis on intervention study that incorporate stakeholder insights focus on school meals. The first goal of identifying food waste drivers was achieved by the systematically reviewing on peer-reviewed and grey literature. The Motivation-Opportunity-Ability (MOA) framework was applied to frame consumer behavioural drivers and identify levers that could be potentially utilized to reduce food waste. Consumer segmentation was further discussed to provide insights for developing tailored food waste reduction interventions. The second goal required the identification on practical interventions, which has been accomplished by systematic literature review basing on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The efficiency and working mechanism of interventions were evaluated basing on the combination of MOA and behavioural change wheel. Building on the evidence of effective interventions, a roadmap was developed for policymakers and practitioners to lead their own pathway on intervention study and upscaling. The third aim has been achieved with a school meals interventions mapping and the implementation of stakeholder workshops. The method was built on the literature review and then enriched by intervention co-design dialogue among stakeholders. The overall conclusion addressed challenges of food waste determents identification, tailored reduction interventions developing, sustainable consumption promotion with school meals.
