Kixikila - um contrato de financiamento informal

The purpose of the present work is to analyse and provide kixikila legal framework under Angolan law. Kixikila, despite being a legally atypical agreement, is a socially typical contract, governed essentially by the practices and customs in Angola and concluded throughout the country. With the above purpose in mind, this thesis is structured in five chapters: the first one aims at better understanding its features and, therefore, it describes the kixikila in accordance with oral research, direct observation and the contributions of scholars that have examined this matter. The second chapter aims at qualifying the kixikila as a legal transaction. For this purpose, we have analysed its requirements, formation stages, content and form, characteristics, rights and obligations of the parties, effects and compliance. We have also covered the reasons that explain why this type of agreement shall be legally protected in line with the protection conferred upon other legal agreements, taking into account its economic and social function. The third chapter covers the vicissitudes which may occur during the term of the kixikila agreement, as well as the enforcement mechanisms in face of breach and its termination. The fourth chapter aims at qualifying this agreement by comparing its most relevant characteristics with those of typical agreements, with a view to determining its legal nature based upon the similarity with other contractual types. This chapter further makes a comparative synthesis between the contracts in analysis. The fifth chapter analyses the legal nature and legal framework applicable to kixikila taking into account mixed-purpose contracts and sui generis contracts. We conclude that practices and customs in Angola take precedence as regards kixikila. Lastly, we attach additional information, such as excerpts of interviews with some individuals intervening in kixikila, the functional structure of kixikila and examples of kixikila, as well as demonstrative lists of countries where this type of agreement takes place and the obligations arising therefrom.

Sustained competitive advantage of different sized multinational corporations in rural base of the pyramid markets

This thesis explores how multinational corporations of different sizes create barriers to imitation and therefore sustain competitive advantage in rural and informal Base of the Pyramid economies. These markets require close cooperation with local partners in a dynamic environment that lacks imposable property rights and follows a different rationale than developed markets. In order to explore how competitive advantage is sustained by different sized multinational corporations at the Base of the Pyramid, the natural-resource-based view and the dynamic capabilities perspective are integrated. Based on this integration the natural-resource-based view is extended by identifying critical dynamic capabilities that are assumed to be sources of competitive advantage at the Base of the Pyramid. Further, a contrasting case study explores how the identified dynamic capabilities are protected and their competitive advantage is sustained by isolating mechanisms that create barriers to imitation for a small to medium sized and a large multinational corporation. The case study results give grounds to assume that most resource-based isolating mechanisms create barriers to imitation that are fairly high for large and established multinational corporations that operate at the rural Base of the Pyramid and have a high product and business model complexity. On the contrary, barriers to imitation were found to be lower for young and small to medium sized multinational corporations with low product and business model complexity that according to some authors represent the majority of rural Base of the Pyramid companies. Particularly for small to medium sized multinational corporations the case study finds a relationship- and transaction-based unwillingness of local partners to act opportunistically rather than a resource-based inability to imitate. By offering an explanation of sustained competitive advantage for small to medium sized multinational corporations at the rural Base of the Pyramid this thesis closes an important research gap and recommends to include institutional and transaction-based research perspectives.

Development and psychometric properties of ECPICID-AVC to measure informal caregivers’ skills when caring for older stroke survivors at home

Introduction: Informal caregivers provide a significant part of the total care needed by dependent older people poststroke. Although informal care is often the preferred option of those who provide and those who receive informal care, informal caregivers often report lack of preparation to take care of older dependent people. This article outlines the development and psychometric testing of informal caregivers’ skills when providing care to older people after a stroke – ECPICID-AVC. Design: Prospective psychometric instrument validation study. Methods: Eleven experts participated in a focus group in order to delineate, develop and validate the instrument. Data were gathered among adult informal caregivers (n = 186) living in the community in Northern Portugal from August 2013 to January 2014. Results: The 32-item scale describes several aspects of informal caregiver’s skills. The scale has eight factors: skill to feed/hydrate by nasogastric feeding, skill to assist the person in personal hygiene, skill to assist the person for transferring, skill to assist the person for positioning, skill to provide technical aids, skill to assist the person to use the toilet, skill to feed/hydrate and skill to provide technical aids for dressing/undressing. Analysis demonstrated adequate internal consistency (Cronbach’s alpha = 0.83) and good temporal stability 0.988 (0.984–0.991). Conclusion: The psychometric properties of the measurement tool showed acceptable results allowing its implementation in clinical practice by the nursing community staff for evaluating practical skills in informal caregivers when providing care to older stroke survivors living at home.

Cortisol, family coping and burden in informal caregivers of addicts

This study focuses on the prospective mediation role of family coping between burden and cortisol levels in informal caregivers of addicts as well as on the feasible use of two different ways to analyse the salivary cortisol levels. Participants were 120 Portuguese informal caregivers of addicts. The cortisol samples were collected at awakening, 45 minutes later and after a 30 minute presentation of images taken from the International Affective Picture System. Family coping and caregiver burden were measured using the Portuguese versions of the Caregiver Reaction Assessment, and the Family Crisis Oriented Personal Evaluation Scale. Cortisol samples were collected in salivettes and the results were computed in order to determine the Area Under the Curve scores (AUCg, AUCi). Results found family coping to be negatively correlated with burden and AUCg levels (i.e. overall intensity) and positively correlated with either AUCg and AUCi (i.e. change over time). The mediation model revealed that family coping was a partial mediator in the relationship between the burden and AUCg levels. Therefore, Family Coping appears to be an essential variable in understanding the stress response and should be considered in further studies and interventions. In addition, the use of two different formulas for calculating cortisol levels provided important new information concerning the relationship between cortisol, burden and family coping. It seems that burden has a more profound effect on the overall intensity of the neuroendocrine response to caregiver stress and not so much on the sensitivity of the system.

La lógica de la protección: la identificación de los sujetos protegidos por el derecho del trabajo. Los aportes de la enseñanza social de la iglesia a esta rama del derecho. La protección de los trabajadores del sector informal. Realidad y prospectiva.

El nuevo escenario de las relaciones laborales, se afirma, ha puesto en crisis el concepto de “dependencia” el cual no resulta ya eficaz para identificar al sujeto a proteger en el contrato de trabajo. Si la tesis es verdadera se afecta la toma de decisiones institucionales en el derecho del trabajo para el nuevo escenario, desde que aquel concepto tiene la función de individualización del sujeto “trabajador” para la imputación de los derechos y obligaciones. Sin embargo, parecería que lo que está detrás de un aparente problema conceptual tiene que ver más con una decisión valorativa en relación con el alcance de la “protección” que las leyes deberían garantizar a los trabajadores. En otras palabras, las discusiones en torno al concepto de “dependencia” están en función de la elección y configuración de las propiedades relevantes que caracterizan lógicamente al sujeto de protección: según se decida y conozca por “sujeto a proteger”, serán los diferentes modos de entender la “dependencia”. Si lo anterior se acepta, la doctrina social de la Iglesia como una ética crítica (justificada) tiene fuerte razones para intervenir en el debate y en la construcción del concepto de “dependencia” como una aporte a la toma de decisiones institucionales.
