    An empirical investigation of the relationship between integration, dynamic capabilities and performance in supply chains

    Get PDF
    This research aimed to develop an empirical understanding of the relationships between integration, dynamic capabilities and performance in the supply chain domain, based on which, two conceptual frameworks were constructed to advance the field. The core motivation for the research was that, at the stage of writing the thesis, the combined relationship between the three concepts had not yet been examined, although their interrelationships have been studied individually. To achieve this aim, deductive and inductive reasoning logics were utilised to guide the qualitative study, which was undertaken via multiple case studies to investigate lines of enquiry that would address the research questions formulated. This is consistent with the author’s philosophical adoption of the ontology of relativism and the epistemology of constructionism, which was considered appropriate to address the research questions. Empirical data and evidence were collected, and various triangulation techniques were employed to ensure their credibility. Some key features of grounded theory coding techniques were drawn upon for data coding and analysis, generating two levels of findings. These revealed that whilst integration and dynamic capabilities were crucial in improving performance, the performance also informed the former. This reflects a cyclical and iterative approach rather than one purely based on linearity. Adopting a holistic approach towards the relationship was key in producing complementary strategies that can deliver sustainable supply chain performance. The research makes theoretical, methodological and practical contributions to the field of supply chain management. The theoretical contribution includes the development of two emerging conceptual frameworks at the micro and macro levels. The former provides greater specificity, as it allows meta-analytic evaluation of the three concepts and their dimensions, providing a detailed insight into their correlations. The latter gives a holistic view of their relationships and how they are connected, reflecting a middle-range theory that bridges theory and practice. The methodological contribution lies in presenting models that address gaps associated with the inconsistent use of terminologies in philosophical assumptions, and lack of rigor in deploying case study research methods. In terms of its practical contribution, this research offers insights that practitioners could adopt to enhance their performance. They can do so without necessarily having to forgo certain desired outcomes using targeted integrative strategies and drawing on their dynamic capabilities

    Tesis por compendio[ES] El objetivo principal de la presente tesis es dilucidar los aspectos del modelo de habilidades, motivación y oportunidades (modelo AMO) que permitan determinar la relación que existe entre las prácticas de RRHH y la mejora de los resultados a nivel organizacional o individual. El objetivo se vehicula a través de preguntas de investigación específicas. Además, a través de métodos estadísticos evaluamos el alcance y difusión de los sistemas de alta implicación en el contexto laboral español, que posee unas particularidades específicas. Finalmente, investigamos qué modelo de interacción predice mejor la satisfacción laboral a nivel individual, el sumativo o el multiplicativo, lo cual constituye una de las grandes cuestiones no resueltas hasta la fecha. De nuestra investigación se desprende que el modelo AMO proporciona una estructura apropiada para explorar la relación entre la gestión de RRHH y los resultados a distintos niveles. Muchas investigaciones articulan sus análisis en base a las agrupaciones de prácticas planteadas por el modelo, y numerosos estudios confirman los efectos positivos de los sistemas de alta implicación. Sin embargo, no existe un consenso claro que permita generalizar los resultados y establecer una metodología única. De acuerdo con nuestra investigación, existen dos razones. En primer lugar, hay una gran variedad de enfoques metodológicos, que conducen a resultados muy diversos. Por otro lado, el modelo AMO se integra en un sistema de relaciones complejo, donde además de los mecanismos que moderan las relaciones internas de los sistemas de RRHH y los resultados, operan otros factores organizacionales, personales y externos. Puesto que existen múltiples realidades, definir políticas que garanticen un modelo de gestión único que se adapte a cualquier situación es complejo. Sin embargo, las evidencias demostradas en la literatura juegan sin duda un papel relevante a la hora de tomar decisiones. Con respecto a la difusión y grado de uso de los sistemas de RRHH en el contexto español, nuestros resultados indican que existe poca influencia de incentivos económicos basados en el rendimiento, quizás debido a la rigidez de la legislación laboral. Los modelos planteados, relacionados con la aplicación formal de sistemas de alta implicación tampoco predicen en gran medida los resultados individuales, aunque sí apuntan a que la categoría de habilidades, y en menor medida la de oportunidades tienen un efecto mayor sobre la satisfacción laboral. Sin embargo, observamos que muchos empleados tienen percepciones positivas en relación con la capacidad de participación, el trabajo en equipo, el intercambio de información, o la formación en el puesto de trabajo, que podrían no estar vinculadas con el diseño y la implantación formal de sistemas de RRHH. En este sentido, algunos estudios evidencian las diferencias entre España y otros países de referencia en relación con la utilización de prácticas de alta implicación. Esta tesis ofrece diversas contribuciones. En primer lugar, realizamos una síntesis exhaustiva de las características del modelo AMO y sus implicaciones teóricas y prácticas, y señalamos los aspectos que dificultan la generalización de resultados. En segundo lugar, analizamos el grado de uso de los sistemas de alta implicación en el contexto español, señalando las posibles carencias. Nuestras conclusiones pueden fomentar el desarrollo de medidas para incrementar la participación de los empleados, así como para romper las barreras que ralentizan la implantación de los sistemas de alta implicación. Por último, evaluamos la validez de los enfoques sumativo y multiplicativo del modelo para predecir la satisfacción laboral. Contribuimos de este modo al creciente interés por las percepciones de los empleados y los resultados a nivel individual, así como a la conveniencia de explorar enfoques distintos al aditivo para confirmar las supuestas sinergias de los sistemas de alta implicación.[CA] L'objectiu principal de la present tesi és dilucidar els aspectes del model d'habilitats, motivació i oportunitats (model AMO) que permeten determinar la relació que existeix entre les pràctiques de RRHH i la millora dels resultats a nivell organitzacional o individual. L'objectiu es vehicula a través de preguntes d'investigació específiques. A més, a través de mètodes estadístics avaluem l'abast i difusió dels sistemes d'alta implicació en el context laboral espanyol, que posseeix unes particularitats específiques. Finalment, investiguem quin model d'interacció prediu millor la satisfacció laboral a nivell individual, el sumatiu o el multiplicador, la qual cosa constitueix una de les grans qüestions no resoltes fins hui. De la nostra investigació es desprén que el model AMO proporciona una estructura apropiada per a explorar la relació entre la gestió de RRHH i els resultats a diferents nivells. Moltes investigacions articulen les seues anàlisis sobre la base de les agrupacions de pràctiques plantejades pel model, i nombrosos estudis confirmen els efectes positius dels sistemes d'alta implicació. No obstant això, no existeix un consens clar que permeta generalitzar els resultats i establir una metodologia única. D'acord amb la nostra investigació, existeixen dues raons. En primer lloc, hi ha una gran varietat d'enfocaments metodològics, que condueixen a resultats molt diversos. D'altra banda, el model AMO s'integra en un sistema de relacions complex, on a més dels mecanismes que moderen les relacions internes dels sistemes de RRHH i els resultats, operen altres factors organitzacionals, personals i externs. Com que existeixen múltiples realitats, definir polítiques que garantisquen un model de gestió únic que s'adapte a qualsevol situació és complex. No obstant això, les evidències demostrades en la literatura juguen sens dubte un paper rellevant a l'hora de prendre decisions. Respecte a la difusió i grau d'ús dels sistemes de RRHH en el context espanyol, observem diversos aspectes. Els nostres resultats indiquen que existeix poca influència d'incentius econòmics basats en el rendiment, potser a causa de la rigidesa de la legislació laboral. Els models plantejats, relacionats amb l'aplicació formal de sistemes d'alta implicació tampoc prediuen en gran manera els resultats individuals, encara que sí que apunten al fet que la categoria d'habilitats, i en menor mesura la d'oportunitats tenen un efecte major sobre la satisfacció laboral. No obstant això, observem que molts empleats tenen percepcions positives en relació amb la capacitat de participació, el treball en equip, l'intercanvi d'informació, o la formació en el lloc de treball, que podrien no estar vinculades amb el disseny i la implantació formal de sistemes de RRHH. En aquest sentit, alguns estudis evidencien les diferències entre Espanya i altres països de referència en relació amb la utilització de pràctiques d'alta implicació. Aquesta tesi ofereix diverses contribucions. En primer lloc, realitzem una síntesi exhaustiva de les característiques del model AMO i les seues implicacions teòriques i pràctiques, i assenyalem els aspectes que dificulten la generalització de resultats. En segon lloc, analitzem el grau d'ús dels sistemes d'alta implicació en el context espanyol, assenyalant les possibles mancances. Les nostres conclusions poden fomentar el desenvolupament de mesures per a incrementar la participació dels empleats, així com per a trencar les barreres que alenteixen la implantació dels sistemes d'alta implicació. Finalment, avaluem la validesa dels enfocaments sumatiu i multiplicador del model per a predir la satisfacció laboral. Contribuïm d'aquesta manera al creixent interés per les percepcions dels empleats i els resultats a nivell individual, així com a la conveniència d'explorar enfocaments diferents a l'additiu per a confirmar les suposades sinergies dels sistemes d'alta implicació.[EN] The main objective of this thesis is to elucidate the aspects of the abilities, motivation, and opportunities model (AMO model) that allow determining the relationship between HR practices and organizational or individual results improvement. The objective is conveyed through specific research questions. In addition, we assess the scope of high-involvement work systems (HIWS) in the Spanish labour context, which has specific particularities. Finally, we compare the predictive capacity of the summative and multiplicative approaches at the individual level, which is one of the unresolved questions to date. Our research shows that the AMO model provides an appropriate structure for exploring the relationship between HR management and outcomes at different levels. Many studies articulate their analyses based on the groupings of practices proposed by the model, and numerous studies confirm the positive effects of HIWS. However, there is no clear consensus to generalize the results and establish a single methodology. According to our research, there are two main reasons. First, there is a wide range of methodological approaches, which lead to very mixed results. On the other hand, the AMO model is integrated into a complex system of relationships, where in addition to the mechanisms that moderate the internal relationships of HR systems and the results, other organizational, personal, and external factors that shape these relationships operate. Since there are multiple realities, defining policies guaranteeing a single management model that adapts to any situation is complex. However, the evidence demonstrated in the HR literature undoubtedly plays an important role when making decisions. We observe several facets regarding the use of HR systems in the Spanish context. Our results indicate little influence of performance-based incentives, perhaps due to the rigidity of labour legislation. Concerning the formal implementation of HIWS, our proposed models do not predict, to a large extent, variations in job satisfaction, although abilities and opportunities categories have greater effects than motivation. Nevertheless, many employees have positive perceptions regarding engagement, teamwork, information sharing, or on-the-job training, which may not be linked to the formal implementation of HR systems. In this sense, some studies show differences between Spain and other reference countries concerning the use of HIWP. This thesis offers several contributions. First, we offer an exhaustive synthesis of the AMO model features and its theoretical and practical implications, and we point out the aspects that hinder the generalization of results. In-depth knowledge of the model acts as a guide for future research. Secondly, we analyse the degree of use of HIWS in the Spanish context, pointing out the possible shortcomings. Our conclusions may promote the development of policies to increase employee autonomy and participation, job satisfaction, and competitiveness, as well as to break down the institutional and cultural barriers that slow the implementation of HIWS. Finally, we assess the validity of the model's summative and multiplicative approaches to predicting job satisfaction. We thus contribute to the growing interest in employee perceptions and outcomes at the individual level and the desirability of exploring approaches other than additive to confirm the supposed synergies of HIWS.Martínez Tomás, J.

    Linear-Time Temporal Answer Set Programming

    [Abstract]: In this survey, we present an overview on (Modal) Temporal Logic Programming in view of its application to Knowledge Representation and Declarative Problem Solving. The syntax of this extension of logic programs is the result of combining usual rules with temporal modal operators, as in Linear-time Temporal Logic (LTL). In the paper, we focus on the main recent results of the non-monotonic formalism called Temporal Equilibrium Logic (TEL) that is defined for the full syntax of LTL but involves a model selection criterion based on Equilibrium Logic, a well known logical characterization of Answer Set Programming (ASP). As a result, we obtain a proper extension of the stable models semantics for the general case of temporal formulas in the syntax of LTL. We recall the basic definitions for TEL and its monotonic basis, the temporal logic of Here-and-There (THT), and study the differences between finite and infinite trace length. We also provide further useful results, such as the translation into other formalisms like Quantified Equilibrium Logic and Second-order LTL, and some techniques for computing temporal stable models based on automata constructions. In the remainder of the paper, we focus on practical aspects, defining a syntactic fragment called (modal) temporal logic programs closer to ASP, and explaining how this has been exploited in the construction of the solver telingo, a temporal extension of the well-known ASP solver clingo that uses its incremental solving capabilities.Xunta de Galicia; ED431B 2019/03We are thankful to the anonymous reviewers for their thorough work and their useful suggestions that have helped to improve the paper.

    Art, youth engagement and informality in the context of HIV prevention have been generally ignored by most researchers and stakeholders within the HIV programming and policy arenas, thus silencing the plight of urban youth infected with and affected by HIV/AIDS. In response, this thesis draws on the case of peri-urban settings of Kampala, Uganda to bring geographies of applied sculpture, HIV/AIDS prevention, and youth empowerment into dialogue, informed by the notions of art having the capacity to move beyond the spaces of galleries into an expanded field, and thus, beyond the visual and into the social spheres. In liaison with local NGOs (The Uganda AIDS Support Organisation - TASO, National Guidance and Empowerment Network for People Living with HIV/AIDS - NGEN+ and Lungujja Community based Health care Organisation – LUCOHECO, it adopts a mixed methodological approach, including applied art and participatory techniques - observation, video, storytelling, and interviews, to understand the lived experiences of young people (15-24 years) in marginalized spaces in Kampala. The thesis first examines the general context of using ethnography and applied social sculpture to explore every day experiences by facilitating the engagement of young people in open communication about the epidemic. This is intended to enable them to act in confronting stigma, taboos, and their precarious existence, while raising their awareness about HIV/AIDS. The thesis then explores the everyday precarious existence of young people in informal settings in Kampala. It proceeds to examine how workshops with these young people allowed collective engagement which, in turn, influenced the creation of artworks envisioned to act as communication tools for raising awareness of HIV/AIDS with the potential for livelihood benefits. Finally, the thesis examines young people’s active involvement in participatory workshops for HIV/AIDS prevention, providing ethnographic evidence regarding the artmaking process, the conversations that ensued as they worked, and the creation of applied objects/forms that enabled them to build their confidence to freely express about the precarities affecting their lives, countering taboos, and encouraging them to change their behaviours and practices while potentially acting as change agents in their own communities. It highlights the significance of stimulating open conversations about HIV/AIDS - as a starting point towards confronting stigma and other aspects of precarity, while advocating for the incorporation of the approach into practice by public health experts, policymakers, and development practitioners. The thesis shows the strengths of applied sculpture as an approach that has potential for making sense of ordinary everyday experiences, finding meaning and crafting clarity of young people’s lived experiences in the context of HIV/AIDS. It concludes that applied sculpture is potentially an important tool in tackling HIV/AIDS and its attendant problems by engendering and facilitating open conversations and social economic development through an engagement with the voices and agency of young people in Uganda and beyond
