Non-Gaussian dynamic Bayesian modelling for panel data

A first order autoregressive non-Gaussian model for analysing panel data is proposed. The main feature is that the model is able to accommodate fat tails and also skewness, thus allowing for outliers and asymmetries. The modelling approach is to gain sufficient flexibility, without sacrificing interpretability and computational ease. The model incorporates individual effects and we pay specific attention to the elicitation of the prior. As the prior structure chosen is not proper, we derive conditions for the existence of the posterior. By considering a model with individual dynamic parameters we are also able to formally test whether the dynamic behaviour is common to all units in the panel. The methodology is illustrated with two applications involving earnings data and one on growth of countries.autoregressive modelling; growth convergence; individual effects; labour earnings; prior elicitation; posterior existence; skewed distributions

Model-based Clustering of non-Gaussian Panel Data

In this paper we propose a model-based method to cluster units within a panel. The underlying model is autoregressive and non-Gaussian, allowing for both skewness and fat tails, and the units are clustered according to their dynamic behaviour and equilibrium level. Inference is addressed from a Bayesian perspective and model comparison is conducted using the formal tool of Bayes factors. Particular attention is paid to prior elicitation and posterior propriety. We suggest priors that require little subjective input from the user and possess hierarchical structures that enhance the robustness of the inference. Two examples illustrate the methodology: one analyses economic growth of OECD countries and the second one investigates employment growth of Spanish manufacturing firmsautoregressive modelling; employment growth; GDP growth convergence; hierarchical prior; model comparison; posterior propriety; skewness

Developing a business innovation perspective of electric vehicle uptake: lessons from Milton Keynes' electric vehicle programme

Electrification of transport forms a major part of British policy for energy and climate change. The formation of the early market for Electric Vehicles (EVs) has been supported through consumer subsidies, regulatory support, and programmes for the deployment of electric vehicle charging infrastructure, but uptake does not seem to be proceeding at the rate needed for meeting policy objectives. The approach pursued by policy actors is consistent with the approach of Strategic Niche Management (SNM), which would call for the creation of protected spaces to facilitate the development of new sociotechnical configurations. The Plugged-in Programme (PiP) in Milton Keynes is an example of creating a protective space. A comparison of PiP and other case studies in the literature of sociotechnical transitions identified a gap in SNM that may shed light on the limitations of EV policy in the UK. Traditionally, SNM has been used to monitor and manage interventions in support of prototype or pre-production vehicles. In consequence, there is no precedent for its application in support of early market technologies. The market introduction of innovative technologies can trigger interrelated technological and behavioural changes, affecting the preferences of producers and consumers while altering the demand structure of the sector. However, SNM does not account for the patterns of use and demand implied in what remain largely technological templates for the future. This thesis begins to develop a framework for the analysis and management of early market strategic niches. Insights from a second discipline, that of social marketing, were sought to complement the analytical tools of SNM. Social marketing is useful for understanding the effect of behavioural and market factors on the adoption of innovative technologies. Social marketing provides a framework for analysing and influencing behaviour in socially beneficial directions. Behaviour and choice are modulated through the application of a marketing orientation, identifying and addressing needs and creating valuable offerings. This research is centred on organizational users of electric vehicles (EVs), and explores the effectiveness of the policy portfolio for addressing the needs of early adopters and for building an early market for EVs. Thematic analysis, a form of qualitative content analysis, is applied to evidence from documentary sources, participant observation and interviews with key organizational actors in the community of pioneering and prospective EV users. The analysis draws on concepts from SNM and social marketing to explore previously neglected forces affecting the early market for EVs, with particular focus on the increasing importance of market selection and the competition presented by an entrenched but socially undesirable incumbent. Contrary to the expectations of policy actors, financial incentives and infrastructure deployment have a limited impact on the choices made by organizational actors. This thesis shows that the processes of learning and embedding that take place within the niche need to be multidimensional. Before a choice can be made, pioneering and prospective adopters of EVs invest considerable effort in the collaborative construction of new patterns of use and demand. This process can be supported by empowering interventions that identify suitable applications (creating multiple sub-niches within the niche) and facilitate the co-construction of new, competitive configurations around them. The models and networks created through this multidimensional, collaborative process translate into capabilities that give distinct advantages to pioneering adopters, allowing them to expand beyond their original niche and outperform the incumbents in mainstream markets

Art in Special Collections: Latino and African American Fine Art and Photography Collections in Academic Institutions

Often university libraries or archive/special collections house large fine art and photographic collections by African American and Latino artists. These collections are frequently hidden due to inadequate funding to promote them, minimal exhibit space, insufficient staffing with requisite exhibition and curatorial expertise, and/or diminished cataloging or digital priority. This article seeks to address the concerns and issues that affect this lack of exposure within academic special collections in both large and small institutions. The intent is to highlight successful strategies that can be used by other repositories seeking to diversify their art and photography holdings

Estrategias socioemocionales para el bullying en estudiantes de una institución educativa de Chiclayo

El presente estudio tuvo objetivo de proponer estrategias socioemocionales para el Bullying en estudiantes de una institución educativa de Chiclayo. Mediante un enfoque cuantitativa y un diseño no experimental - propositivo - descriptivo se utilizó una población de 40 estudiantes de ambos sexos en donde se empleó el Cuestionario de Bullying de 24 ítems para evaluar las dimensiones física, psicológica, social y tecnológica de esta variable; además, se diseñó un plan te intervención de estrategias socioemocionales de 10 sesiones planificadas para una duración de 45 minutos cada una. Los resultados evidenciaron en todas las dimensiones analizadas, se observa que el nivel predominante es el Moderado, bullying físico (37.5%), bullying psicológico (40%), bullying social (52.5%) y bullying tecnológico (48%); sin embargo, aún con porcentajes inferiores el nivel alto también fue identificado en la relación. Por otro lado, se evidenció que la propuesta de estrategias socioemocionales desarrollada es válida con un alto grado de consenso entre los expertos evaluadores. Se concluyó que luego de la problemática identificada en relación al bullying y todas sus dimensiones y, por consiguiente, la ausencia de una convivencia escolar armoniosa y pacífica en las aulas, el plan propuesto resolvería las dificultades evidenciadas
