Gasificação direta de biomassa para produção de gás combustível
The excessive consumption of fossil fuels to satisfy the world necessities of
energy and commodities led to the emission of large amounts of greenhouse
gases in the last decades, contributing significantly to the greatest
environmental threat of the 21st century: Climate Change. The answer to this
man-made disaster is not simple and can only be made if distinct stakeholders
and governments are brought to cooperate and work together. This is
mandatory if we want to change our economy to one more sustainable and
based in renewable materials, and whose energy is provided by the eternal
nature energies (e.g., wind, solar). In this regard, biomass can have a main role
as an adjustable and renewable feedstock that allows the replacement of fossil
fuels in various applications, and the conversion by gasification allows the
necessary flexibility for that purpose. In fact, fossil fuels are just biomass that
underwent extreme pressures and heat for millions of years. Furthermore,
biomass is a resource that, if not used or managed, increases wildfire risks.
Consequently, we also have the obligation of valorizing and using this
resource.
In this work, it was obtained new scientific knowledge to support the
development of direct (air) gasification of biomass in bubbling fluidized bed
reactors to obtain a fuel gas with suitable properties to replace natural gas in
industrial gas burners. This is the first step for the integration and development
of gasification-based biorefineries, which will produce a diverse number of
value-added products from biomass and compete with current petrochemical
refineries in the future. In this regard, solutions for the improvement of the raw
producer gas quality and process efficiency parameters were defined and
analyzed. First, addition of superheated steam as primary measure allowed the
increase of H2 concentration and H2/CO molar ratio in the producer gas without
compromising the stability of the process. However, the measure mainly
showed potential for the direct (air) gasification of high-density biomass (e.g.,
pellets), due to the necessity of having char accumulation in the reactor bottom
bed for char-steam reforming reactions. Secondly, addition of refused derived
fuel to the biomass feedstock led to enhanced gasification products, revealing
itself as a highly promising strategy in terms of economic viability and
environmental benefits of future gasification-based biorefineries, due to the
high availability and low costs of wastes. Nevertheless, integrated techno economic and life cycle analyses must be performed to fully characterize the
process. Thirdly, application of low-cost catalyst as primary measure revealed
potential by allowing the improvement of the producer gas quality (e.g., H2 and
CO concentration, lower heating value) and process efficiency parameters with
distinct solid materials; particularly, the application of concrete, synthetic
fayalite and wood pellets chars, showed promising results. Finally, the
economic viability of the integration of direct (air) biomass gasification
processes in the pulp and paper industry was also shown, despite still lacking
interest to potential investors. In this context, the role of government policies
and appropriate economic instruments are of major relevance to increase the
implementation of these projects.O consumo excessivo de combustíveis fósseis para garantir as necessidades e
interesses da sociedade conduziu à emissão de elevadas quantidades de
gases com efeito de estufa nas últimas décadas, contribuindo
significativamente para a maior ameaça ambiental do século XXI: Alterações
Climáticas. A solução para este desastre de origem humana é de caráter
complexo e só pode ser atingida através da cooperação de todos os governos
e partes interessadas. Para isto, é obrigatória a criação de uma bioeconomia
como base de um futuro mais sustentável, cujas necessidades energéticas e
materiais sejam garantidas pelas eternas energias da natureza (e.g., vento,
sol). Neste sentido, a biomassa pode ter um papel principal como uma matéria prima ajustável e renovável que permite a substituição de combustíveis fósseis
num variado número de aplicações, e a sua conversão através da gasificação
pode ser a chave para este propósito. Afinal, na prática, os combustíveis
fósseis são apenas biomassa sujeita a elevada temperatura e pressão durante
milhões de anos. Além do mais, a gestão eficaz da biomassa é fundamental
para a redução dos riscos de incêndio florestal e, como tal, temos o dever de
utilizar e valorizar este recurso.
Neste trabalho, foi obtido novo conhecimento científico para suporte do
desenvolvimento das tecnologias de gasificação direta (ar) de biomassa em
leitos fluidizados borbulhantes para produção de gás combustível, com o
objetivo da substituição de gás natural em queimadores industriais. Este é o
primeiro passo para o desenvolvimento de biorrefinarias de gasificação, uma
potencial futura indústria que irá providenciar um variado número de produtos
de valor acrescentado através da biomassa e competir com a atual indústria
petroquímica. Neste sentido, foram analisadas várias medidas para a melhoria
da qualidade do gás produto bruto e dos parâmetros de eficiência do processo.
Em primeiro, a adição de vapor sobreaquecido como medida primária permitiu
o aumento da concentração de H2 e da razão molar H2/CO no gás produto sem
comprometer a estabilidade do processo. No entanto, esta medida somente
revelou potencial para a gasificação direta (ar) de biomassa de alta densidade
(e.g., pellets) devido à necessidade da acumulação de carbonizados no leito
do reator para a ocorrência de reações de reforma com vapor. Em segundo, a
mistura de combustíveis derivados de resíduos e biomassa residual florestal
permitiu a melhoria dos produtos de gasificação, constituindo desta forma uma
estratégia bastante promissora a nível económico e ambiental, devido à
elevada abundância e baixo custo dos resíduos urbanos. Contudo, devem ser
efetuadas análises técnico-económicas e de ciclo de vida para a completa
caraterização do processo. Em terceiro, a aplicação de catalisadores de baixo
custo como medida primária demonstrou elevado potencial para a melhoria do
gás produto (e.g., concentração de H2 e CO, poder calorífico inferior) e para o
incremento dos parâmetros de eficiência do processo; em particular, a
aplicação de betão, faialite sintética e carbonizados de pellets de madeira,
demonstrou resultados promissores. Finalmente, foi demonstrada a viabilidade
económica da integração do processo de gasificação direta (ar) de biomassa
na indústria da pasta e papel, apesar dos parâmetros determinados não serem
atrativos para potenciais investidores. Neste contexto, a intervenção dos
governos e o desenvolvimento de instrumentos de apoio económico é de
grande relevância para a implementação destes projetos.Este trabalho foi financiado pela The Navigator Company e por Fundos Nacionais através da Fundação para a Ciência e a Tecnologia (FCT).Programa Doutoral em Engenharia da Refinação, Petroquímica e Químic

Examining the Impact of Personal Social Media Use at Work on Workplace Outcomes
A noticable shift is underway in today’s multi-generational workforce. As younger employees propel digital workforce transformation and embrace technology adoption in the workplace, organisations need to show they are forward-thinking in their digital transformation strategies, and the emergent integration of social media in organisations is reshaping internal communication strategies, in a bid to improve corporate reputations and foster employee engagement. However, the impact of personal social media use on psychological and behavioural workplace outcomes is still debatebale with contrasting results in the literature identifying both positive and negative effects on workplace outcomes among organisational employees.
This study seeks to examine this debate through the lens of social capital theory and study personal social media use at work using distinct variables of social use, cognitive use, and hedonic use. A quantitative analysis of data from 419 organisational employees in Jordan using SEM-PLS reveals that personal social media use at work is a double-edged sword as its impact differs by usage types. First, the social use of personal social media at work reduces job burnout, turnover intention, presenteeism, and absenteeism; it also increases job involvement and organisational citizen behaviour. Second, the cognitive use of personal social media at work increases job involvement, organisational citizen behaviour, employee adaptability, and decreases presenteeism and absenteeism; it also increases job burnout and turnover intention. Finally, the hedonic use of personal social media at work carries only negative effects by increasing job burnout and turnover intention.
This study contributes to managerial understanding by showing the impact of different types of personal social media usage and recommends that organisations not limit employee access to personal social media within work time, but rather focus on raising awareness of the negative effects of excessive usage on employee well-being and encourage low to moderate use of personal social media at work and other personal and work-related online interaction associated with positive workplace outcomes. It also clarifies the need for further research in regions such as the Middle East with distinct cultural and socio-economic contexts

After Creation: Intergovernmental Organizations and Member State Governments as Co-Participants in an Authority Relationship
This is a re-amalgamation of what started as one manuscript and became two when the length proved to be more than any publisher wanted to consider. The splitting consisted of removing what are now Parts 3, 4, and 5 so that the manuscript focused on the outcome-related shared beliefs holding an authority relationship together. Those parts were last worked on in 2018. The rest were last worked on in late 2021 but also remain incomplete.
The relational approach adopted in this study treats intergovernmental organizations and the governments of member states as co-participants in an authority relationship with the governments of their member states. Authority relationships link two types of actor, defined by their authority-holder or addressee role in the relationship, through a set of shared beliefs about why the relationship exists and how the participants should fulfill their respective roles. The IGO as authority holder has a role that includes a right to instruct other actors about what they should or should not do; the governments of member states as addressees are expected to comply with the instructions. Three sets of shared beliefs provide the conceptual “glue” holding the relationship together. The first defines the goal of the collective effort, providing both the rationale for having the authority relationship and providing a lode star for assessments of the collective effort’s success or lack of success. The second set defines the shared understanding about allocation of roles and the process of interaction by establishing shared expectations about a) the selection process by which particular actors acquire authority holder roles, b) the definitions identifying one or more categories of addressees expected to follow instructions, and c) the procedures through which the authority holder issues instructions. The third set focus on the outcomes of cooperation through the relationship by defining a) the substantive areas in which the authority holder may issue instructions, b) the bases for assessing the relevance actions mandated in instructions for reaching the goal, and c) the relative efficacy of action paths chosen for reaching the goal as compared to other possible action paths.
Using an authority relationship framework for analyzing cooperation through IGOs highlights the inherently bi-directional nature of IGO-member government activity by viewing their interaction as involving a three-step process in which the IGO as authority holder decides when to issue what instruction, the member state governments as followers react to the instruction with anything from prompt and full compliance through various forms of pushback to outright rejection, and the IGO as authority holder responds to how the followers react with efforts to increase individual compliance with instructions and reinforce continuing acceptance of the authority relationship. Foregrounding the dynamics produced by the interaction of these two streams of perception and action reveals more clearly how far intergovernmental organizations acquire capacity to operate as independent actors, the dynamic ways they maintain that capacity, and how much they influence member governments’ beliefs and actions at different times. The approach fosters better understanding of why, when, and for how long governments choose cooperation through an IGO even in periods of rising unilateralism
A psychobiographical study of the life story of Ellen Pakkies
Ellen Pakkies’ memoir highlights numerous psychosocial issues, such as child abuse, gender based violence, sexual abuse, child neglect and, in particular, the aftermath of substance abuse.
The overarching aim of this study was to describe and interpret the unique and complex
development process of Ellen Pakkies across her lifespan and to understand her traumatic life
experiences and that as a caregiver of a methamphetamine addict, as well as the resilient
outcome of her ordeal. Ellen’s development over her lifespan and the resilient outcome
displayed was primarily guided by Kümpfer’s (2002) transactional resilience model and
supplemented by Baltes’ (1987) lifespan development perspective theory. This was a single case, qualitative psychobiographical study of the life of Ellen Pakkies. Ellen was chosen as the
research subject of this psychobiographical study due to the uniqueness and complexity of her
life story. Life history material in the form of the book Dealing in Death, radio interviews,
speeches, and court transcripts aided in creating a biographical sketch of Ellen’s life. This study
suggests that a single factor cannot be ascribed to the tragic occurrence of Ellen strangling her
son to death. It is rather the amalgamation of traumatic experiences and prolonged abuse that
Ellen was subjected to from childhood to adulthood that contributed to her reaching her limit.PsychologyM.A. (Psychology
Managing global virtual teams in the London FinTech industry
Today, the number of organisations that are adopting virtual working arrangements has exploded, and the London FinTech industry is no exception. During recent years, FinTech companies have increasingly developed virtual teams as a means of connecting and engaging geographically dispersed workers, lowering costs, and enabling greater speed and adaptability.
As the first study in the United Kingdom regarding global virtual team management in the FinTech industry, this DBA research seeks answers to the question, “What makes for the successful management of a global virtual team in the London FinTech industry?”. Straussian grounded-theory method was chosen as this qualitative approach lets participants have their own voice and offers some flexibility. It also allows the researcher to have preconceived ideas about the research undertaking.
The research work makes the case for appreciating the voice of people with lived experiences. Ten London-based FinTech Managers with considerable experience running virtual teams agreed to take part in this study. These Managers had spent time working at large, household-name firms with significant global reach, and one had recently become founder and CEO of his own firm, taking on clients and hiring contract staff from around the world. At least eight of the other participants were senior ‘Heads’ of various technology teams and one was a Managing Director working at a ‘Big Four’ consultancy. They had all (and many still did) spent years running geographically distributed teams with members as far away as Pacific Asia and they were all keen to discuss that breadth of experience and the challenges they faced.
Results from these in-depth interviews suggested that there are myriad reasons for a global virtual team, from providing 24 hour, follow-the-sun service to locating the most cost-effective resources with the highest skills. It also confirmed that there are unique challenges to virtual management and new techniques are required to help navigate virtual managers through them.
Managing a global virtual team requires much more than the traditional management competencies. Based on discussion with the respondents, a set of practical recommendations for global virtual team management was developed and covered a wide range of issues related to recruitment and selection, team building, developing standard operating procedures, communication, motivation, performance management, and building trust
Exploring individual characteristics related to community-based sentence compliance: Is there an association between neuropsychological functioning, traumatic brain injury, and non-compliance with a community-based sentence?
Non-compliance with a community-based sentence can result in serious consequences for an individual, including imprisonment. Probation officers, who supervise those on community sentences, play an essential role in supporting compliance and determining how to respond when non-compliance occurs; however, little research has explored how probation officers use their discretion. Neuropsychological dysfunction and a history of traumatic brain injury (TBI) are overrepresented amongst incarcerated offenders and associated with poorer outcomes (recidivism, treatment attrition, disciplinary infractions). However, much less is known about the neuropsychological function and history of TBI amongst community-based offenders (i.e., supervisees). Thus, this research project sought to understand probation officers’ perspectives on and responses to non-compliance and explore the association between a supervisee’s compliance and current neuropsychological functioning and recent TBI.
The first study involved two focus groups with 17 New Zealand probation officers; the aim was to explore probation officers’ views on compliance and how they practice supervision. All probation officers reported using ‘social worker’ type, evidenced-based practices such as building quality relationships and using motivational interviewing. Probation officers viewed problems with cognitive skills as a key barrier to sentence compliance and reported using various strategies to support the compliance of supervisees with cognitive issues.
The second study, involved 106 adult men (n = 82, 77.4%) and women (n = 24, 22.6%) on community sentences who participated in an initial interview that included a screen for a history of TBI and consent to collect compliance (arrests, sentence violations) and related variables (e.g., risk scores) from the New Zealand Department of Corrections database and police records over six months. At the conclusion of the initial interview, supervisees were invited to return and complete neuropsychological tests. Sixty-four men (n = 47, 73.4%) and women (n = 17, 26.5%) returned and completed the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Comprehensive Trail Making Test, and Color-Word Inference Test, and the Behavior Rating Inventory of Executive Function- Adult Version (BRIEF-A). Twenty-six probation officers, whose supervisees participated in the study, were interviewed regarding their supervisees’ compliance.
The first manuscript from this study focused on the executive functioning of this sample compared to a normative sample and investigated the association between executive functioning and compliance with sentence conditions. The results indicated that the community-based sample had significantly poorer executive functioning compared to a normative sample. Still, contrary to what was expected, those supervisees who complied with their sentence conditions had poorer executive functioning than those who were non-compliant. However, exploratory analyses showed that those with poorer executive functioning received more probation officer support to comply with sentence conditions.
The second manuscript described the sample’s neuropsychological function compared to a normative sample and investigated the association between sustaining a TBI in the last year (i.e., within the year prior to joining the study) and current neuropsychological function. We then explored if a TBI in the last year or current neuropsychological function were associated with compliance with sentence conditions and compliance with the law (i.e., being arrested). The results indicated that the community-based sample’s neuropsychological functioning was significantly poorer than a normative sample. Our findings also suggested that a TBI in the last year was a significant predictor of arrest, even when controlling for risk of reconviction and current substance use. However, a recent TBI was not associated with non-compliance with sentence conditions nor with poorer performance on the neuropsychological tests. In addition, no significant associations were found between performance on the neuropsychological tests and either measure of non-compliance.
Overall, the results from this thesis suggested that individual characteristics like TBI and neuropsychological functioning impact compliance with a community-based sentence in different ways: A recent TBI was predictive of re-arrest while serving a community sentence, and poorer neuropsychological functioning was significantly associated with increased support from the probation officer to comply.
The main implications of this research for corrections departments are that supervisees on a community sentence with poor neuropsychological functioning or a recent TBI may need additional monitoring or support to reduce the risk of non-compliance and reoffending. While further research needs to be undertaken to inform any changes in policy or practices, the results from this thesis suggest that community corrections would benefit from the implementation of services and screens to target important responsivity issues like TBI and poor neuropsychological functioning. Corrections departments attention to these issues may help alleviate the risk of individuals getting trapped in the criminal justice system for non-criminal activities (e.g., not attending an appointment)
A History of Psychological Boredom: The Utility of Boredom in the Practice of Psychological Science
The 100-year plus history of psychologists attempting to establish boredom as a quantifiable construct provides insight into the problems associated with how psychology adopts its subject matter. By borrowing terms from the public and assuming they represent universal aspects of human nature, the discipline has spurred critical inquiry regarding the practices hidden assumptions and theory. In particular, boredom, with its associations with both existential and trivial concerns, exposes the limitations of the practice of scientific psychology and reflects the disciplines own conflicted identity. In order to facilitate an examination of these theoretical issues, this historical examination focuses on the failed attempts by 1970s personality psychology and 1990s positive psychology to domesticate the concept. With the inclusion of the publics boredom discourse during these decades, the cultural influence on these disciplines theorizing is excavated. These influences complicate attempts by psychologists to practice as a science and provide a reason to take pause amid repeated calls to unify the discipline
