THE IMPACT OF TRAINING PROGRAMMES ON WAGES IN FRANCE: AN EVALUATION OF THE “QUALIFYING CONTRACT” USING PROPENSITY SCORES.

This paper evaluates the impact of a widely-used French training programme for youth on earnings. This programme is designed to increase labour market experience and education, validated by a formal diploma. It is not sure, however, whether this diploma and a similar diploma acquired through initial training have the same effect on post-training wages. To answer this question, we contrast the 2003 net wages of a group of participants enrolled in 1998 (the “treatment” group) to the 2003 net wages of a control group. The controls are individuals who completed their initial training in 1998 with diplomas similar to those obtained by the treated at the end of the programme. Using propensity score matching, we find a significantly positive effect of the treatment on the treated: participants in the programme benefit, five years after participation, from a positive wage premium. This suggests that firms do not simply value education: they value it more if it is coupled with some degree of labour market experience.active labour market policies; training programmes for youth; propensity score matching.

An Illustration of the Returns to Training Programmes: The Evaluation of the “Qualifying Contract" in France

We evaluate the labour market outcomes of a French training programme for youth, using a non-experimental sample of individuals who completed their studies (or dropped out) in 1998 and were observed until 2003. We use propensity score matching to estimate the impact of participation on three outcome variables: the net monthly wage, the monthly income and the probability of employment. We find a positive impact of participation on all three outcome variables. Non parametric robustness checks confirmed our results. We explain these results, which contrast with those of previous French studies, by the very strong training content of the programme.active labour market programmes, training programmes for youth, propensity score matching

Contact interaction in an unitary ultracold Fermi gas

An ultracold Fermi atomic gas at unitarity presents universal properties that in the diluted limit can be well described by a contact interaction. By employing a guide function with correct boundary conditions and making simple modifications to the sampling procedure we are able to handle for the first time a true contact interaction in a quantum Monte Carlo calculation. The results are obtained with small variances. Our calculations for the Bertsch and contact parameters are in excellent agreement with published experiments. The possibility of using a more faithfully description of ultracold atomic gases can help uncover features yet unknown of the ultracold atomic gases. In addition, this work paves the way to perform quantum Monte Carlo calculations for systems interacting with contact interactions, where in many cases the description using potentials with finite effective range might not be accurate

Representational organization of novel task sets during proactive encoding

Recent multivariate analyses of brain data have boosted our understanding of the organizational principles that shape neural coding. However, most of this progress has focused on perceptual visual regions (Connolly et al., 2012), whereas far less is known about the organization of more abstract, action-oriented representations. In this study, we focused on humans{\textquoteright} remarkable ability to turn novel instructions into actions. While previous research shows that instruction encoding is tightly linked to proactive activations in fronto-parietal brain regions, little is known about the structure that orchestrates such anticipatory representation. We collected fMRI data while participants (both males and females) followed novel complex verbal rules that varied across control-related variables (integrating within/across stimuli dimensions, response complexity, target category) and reward expectations. Using Representational Similarity Analysis (Kriegeskorte et al., 2008) we explored where in the brain these variables explained the organization of novel task encoding, and whether motivation modulated these representational spaces. Instruction representations in the lateral prefrontal cortex were structured by the three control-related variables, while intraparietal sulcus encoded response complexity and the fusiform gyrus and precuneus organized its activity according to the relevant stimulus category. Reward exerted a general effect, increasing the representational similarity among different instructions, which was robustly correlated with behavioral improvements. Overall, our results highlight the flexibility of proactive task encoding, governed by distinct representational organizations in specific brain regions. They also stress the variability of motivation-control interactions, which appear to be highly dependent on task attributes such as complexity or novelty.SIGNIFICANCE STATEMENTIn comparison with other primates, humans display a remarkable success in novel task contexts thanks to our ability to transform instructions into effective actions. This skill is associated with proactive task-set reconfigurations in fronto-parietal cortices. It remains yet unknown, however, how the brain encodes in anticipation the flexible, rich repertoire of novel tasks that we can achieve. Here we explored cognitive control and motivation-related variables that might orchestrate the representational space for novel instructions. Our results showed that different dimensions become relevant for task prospective encoding depending on the brain region, and that the lateral prefrontal cortex simultaneously organized task representations following different control-related variables. Motivation exerted a general modulation upon this process, diminishing rather than increasing distances among instruction representations

How to increase customer loyalty in the newspaper industry in Portugal : the Global Media Group case

The Global Media Group (GMG) is one of the major media groups in Portugal, being the owner of several brands in the Press, Radio and Internet sectors, namely Diário de Notícias, Jornal de Notícias and TSF, among others. In an industry that is now characterized by the increase in online formats as sources of information, in detriment of traditional media formats such as print newspapers, it is essential to understand how to still increase and maintain customer loyalty in this area. Therefore, this dissertation tackles concepts such as loyalty, perceived value and brand trust, and uses both primary and secondary research methods to answer the problem statement. Through a set of in-depth interviews with group management employees, a focus group among consumers, and a public survey, as well as information from the market and the company, this dissertation provides conclusions on what factors influence buying choice, perceived value and brand trust, how consumers can be characterized, and ultimately how to increase customer loyalty for the GMG and the industry in general. Moreover, the dissertation includes recommendations on specific initiatives the group can use to increase the mentioned variable. Finally, the dissertation includes a chapter with notes for using this dissertation for teaching purposes, with suggestions of questions to be made for students.O Global Media Group é um dos maiores grupos de media em Portugal, detendo marcas nos sectores de Imprensa, Rádio e Internet, nomeadamente o Diário de Notícias, Jornal de Notícias e TSF, entre outras. Numa indústria onde o formato online se impõe cada vez mais como fonte de informação, em detrimento de formatos tradicionais como jornais impressos, é essencial perceber como continuar a aumentar e manter a fidelização dos consumidores nesta área. Como tal, esta dissertação aborda conceitos como lealdade do consumidor, valor percecionado e confiança na marca, e usa métodos de investigação tanto primários como secundários para responder ao problema apresentado. Através de entrevistas estruturadas a dirigentes do Grupo, um focus group a consumidores e um questionário público, bem como informação do mercado e da empresa, esta dissertação apresenta conclusões que ajudam a identificar que fatores influenciam a decisão de compra, o valor percecionado e a confiança na marca, como se podem caracterizar os consumidores, e como, em conclusão, se pode aumentar a lealdade dos consumidores do Global Media Group, e na indústria da imprensa como um todo. Para além disso, a presente dissertação inclui recomendações sobre iniciativas concretas que o grupo pode usar para aumentar a variável mencionada. Finalmente, o documento inclui um capítulo com notas de apoio a lecionar, com sugestões de perguntas que podem ser feitas a alunos

Integrating enterprise architecture and Np Iso 4457

The growing importance of NP ISO 4457 and Enterprise Architecture (EA) is becoming increasingly recognized. However, since they are distinct governance approaches with different perspectives, organizations end up facing several challenges, which leads to efficiency problems, waste of resources and misalignment. This thesis proposes to overcome such problems by integrating NP ISO 4457 with EA. This way, a Reference Architecture is developed, using Archimate, which helps organizations to conform to the Standard’s requirements, by determining how processes and resources are organized and realized. This is a unique contribution, since the Reference Architecture can be applied generically to every organization

Generalising the logistic map through the qq-product

We investigate a generalisation of the logistic map as $x_{n+1}=1-ax_{n}\otimes_{q_{map}} x_{n}$ ($-1 \le x_{n} \le 1$, $0<a\le2$) where $\otimes_q$ stands for a generalisation of the ordinary product, known as $q$-product [Borges, E.P. Physica A {\bf 340}, 95 (2004)]. The usual product, and consequently the usual logistic map, is recovered in the limit $q\to 1$, The tent map is also a particular case for $q_{map}\to\infty$. The generalisation of this (and others) algebraic operator has been widely used within nonextensive statistical mechanics context (see C. Tsallis, {\em Introduction to Nonextensive Statistical Mechanics}, Springer, NY, 2009). We focus the analysis for $q_{map}>1$ at the edge of chaos, particularly at the first critical point $a_c$, that depends on the value of $q_{map}$. Bifurcation diagrams, sensitivity to initial conditions, fractal dimension and rate of entropy growth are evaluated at $a_c(q_{map})$, and connections with nonextensive statistical mechanics are explored.Comment: 12 pages, 23 figures, Dynamics Days South America.
