Etude des facteurs motivationnels influençant l’activité physique et la sédentarité de personnes atteintes de maladies chroniques en contexte de réhabilitation et post-réhabilitation

Parmi les personnes atteintes de maladies chroniques qui participent a des programmes de rehabilitation, deux tiers ne modifient pas leurs comportements a l’issue des interventions. Dans le domaine de l’activite physique et de la sedentarite, identifier les facteurs impliques dans la regulation de ces comportements est donc crucial. En psychologie de la sante, les modeles contemporains indiquent que nos comportements sont le fruit de processus motivationnels a la fois explicites et implicites. Les processus explicites sont definis comme conscients et intentionnels ; a l’inverse, les processus implicites sont caracterises par leur non-intentionnalite et leur caractere plutot inconscient. A mi-chemin entre les domaines de la rehabilitation et la psychologie de la sante, les objectifs de cette these etaient (i) d’examiner le role de processus explicites et implicites dans la prediction des comportements de l’activite physique et de la sedentarite, et (ii) d’etudier la malleabilite de ces variables motivationnelles en contexte de rehabilitation. Les resultats indiquent que les attitudes implicites sont associees avec les niveaux d’activite physique des participants, pendant les programmes et en post-rehabilitation. Les processus explicites (e.g., intentions) etudies dans cette these n’etaient eux pas associes aux comportements. Sur le plan de la malleabilite des processus motivationnels, nos resultats mettent en evidence une amelioration significative mais minime de certaines variables au cours d’un programme de rehabilitation. Ces processus se sont toutefois montres insensibles a une manipulation experimentale delivree en plus des programmes de rehabilitation.
A Comparison of Heuristic and Human Performance on Open Versions of the Traveling Salesperson Problem

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally intractable and, as with the standard TSP, people appear to be able to find good solutions with relative ease. The three heuristics used mechanisms that have been cited as potentially relevant in human performance in the standard task. These were: convex hull, nearest neighbor, and crossing avoidance. We compared heuristic and human performance in terms of lengths of paths, overlap between solutions, and number of crossings. Of the three heuristics, the convex hull appeared to result in the best overall fit with human solutions.
Polymethylmethacrylate imbedded with antibiotics cranioplasty: An infection solution for moderate and large defects reconstruction?

Background: In cases where autologous bone graft reconstruction is not possible (such as comminuted fractures, bone graft reabsorption, or infection) and the use of synthetic material is required, polymethylmethacrylate (PMMA) use is a safe and efficient solution. Studies comparing the incidence of postoperative complications between autologous and synthetic cranioplasty are heterogeneous, not allowing a conclusion of which is the best material for skull defects reconstruction. Current medical literature lacks prospective well-delineated studies with long-term follow-up that analyze the impact of antibiotic use in PMMA cranial reconstruction of moderate and large defects. Methods: A prospective series of patients, who underwent cranioplasty reconstruction with PMMA impregnated with antibiotic, were followed for 2 years. Authors collected data regarding demographic status, clinical conditions, surgical information, and its complications. Results: A total of 58 patients completed full follow-up with a mean group age of 40 years and a male predominance (77%). Major complications that required surgical management were identified in 5 patients, and 10 patients evolved with minor complications. Postoperative surgical site infection incidence was 3.2%. Conclusion: The infection rate in patients submitted to PMMA flap cranioplasty impregnated with antibiotic is significantly inferior comparing to the data described in medical literature. A lower infection incidence impacts secondary endpoints such as minimizing surgical morbidity, mortality, hospitalization period, and, consequently, costs.
A college admissions game for uplink user association in wireless small cell networks

In this paper, the problem of uplink user association in small cell networks, which involves interactions between users, small cell base stations, and macro-cell stations, having often conflicting objectives, is considered. The problem is formulated as a college admissions game with transfers in which a number of colleges, i.e., small cell and macro-cell stations seek to recruit a number of students, i.e., users. In this game, the users and access points (small cells and macro-cells) rank one another based on preference functions that capture the users' need to optimize their utilities which are functions of packet success rate (PSR) and delay as well as the small cells' incentive to extend the macro-cell coverage (e.g., via cell biasing/range expansion) while maintaining the users' quality-of-service. A distributed algorithm that combines notions from matching theory and coalitional games is proposed to solve the game. The convergence of the algorithm is shown and the properties of the resulting assignments are discussed. Simulation results show that the proposed approach yields a performance improvement, in terms of the average utility per user, reaching up to 23% relative to a conventional, best-PSR algorithm.
Redundancy-aware Electromigration checking for mesh power grids

Electromigration (EM) is re-emerging as a significant problem in modern integrated circuits (IC). Especially in power grids, due to shrinking wire widths and increasing current densities, there is little or no margin left between the predicted EM stress and that allowed by the EM design rules. Statistical Electromigration Budgeting (SEB) estimates the reliability of the grid by considering it entirely as a series system. However, a power grid with its many parallel paths has much inherent redundancy. In this paper, we propose a new model to estimate the MTF and reliability of the power grid under the influence of EM, which accounts for these redundancies. We refer to this as the mesh model. To implement the mesh model, we also develop a framework to estimate the change in statistics of an interconnect as its effective-EM current varies. The proposed algorithm is quite fast and has an overall observed empirical complexity of 0(n1.4). The results indicate that the series model, which is currently used in the industry, gives a pessimistic estimate of power grid MTF and reliability by a factor of 3-4.
Portfolio Credit Risk: Top-Down vs. Bottom-Up Approaches

Dynamic reduced form models of portfolio credit risk can be distinguished by the way in which the intensity of the default process is specied. In a bottom up model, the portfolio intensity is an aggregate of the constituent intensities. In a top down model, the portfolio intensity is specied without reference to the constituents. This expository article contrasts these modeling approaches. It emphasizes the role of the information ltration as a modeling tool.
Seeing God Clearly: Meaning-Making and Attributions to God Made by Resident Assistants

Resident Assistants (RAs) at a Christian college in the Midwest were interviewed in order to explore the nature, reasoning, and complexity of attributions to God from their RA-related experiences. Resulting themes found that RAs made attributions to God for experiences of identifiable goodness, which included positive developmental experiences and experiences of deep unity and spirituality. Though RAs often saw themselves as God’s intermediary agents, they also claimed they were limited in their ability to affect deep change. The relationship between their agency and God’s was complex, but RAs sought solace in God’s ultimate control in the midst of their efforts. Implications for practice include facilitating opportunities for RAs to reflect on their experiences to impact spiritual development. Moreover, professionals can teach conceptual and theological tools to help RAs think about how God works in the world and to develop RAs as leaders to better influence wholesome and growing experiences.

We have read this dissertation and recommend that it be approved. CHAPTER 1 iii DEDICATION To My Family CHAPTER 1 iv ACKNOWLEDGMENTS First of all, I would like to express my sincere gratitude to Dr. Jean Andrian for his constant support and guidance. He provided me with encouragement and an interesting working environment that allowed me to finish this dissertation. Lee for their advice and teachings during the course of my career. In addition, I would also like to acknowledge Dr. Chen Liu for his support and understanding during my last semester. I am also indebted to the past and current members of the wireless communications research laboratory for all of our insightful technical conversations and for making my time as a Ph.D. student an enjoyable one. Also thanks are due to the administrative staff at the Department of Electrical and Computer Engineering for their helpful and friendly help and support. Lastly, I want thank my family for all their hard work and want to recognize them as a major source of inspiration and encouragement for pursuing higher education. Polynomial phase modulated (PPM) signals have been shown to provide improved error rate performance with respect to conventional modulation formats under additive white Gaussian noise and fading channels in single-input single-output (SISO) communication systems. In this dissertation, systems with two and four transmit antennas using PPM signals were presented. In both cases we employed full-rate space-time block codes in order to take advantage of the multipath channel. For two transmit antennas, we used the orthogonal space-time block code (OSTBC) proposed by Alamouti and performed symbol-wise decoding by estimating the phase coefficients of the PPM signal using three different methods: maximum-likelihood (ML), sub-optimal ML (S-ML) and the high-order ambiguity function (HAF). In the case of four transmit antennas, we used the full-rate quasi-OSTBC (QOSTBC) proposed by Jafarkhani. However, in order to ensure the best error rate performance, PPM signals were selected such as to maximize the QOSTBC's minimum coding gain distance (CGD). Since this method does not always provide a unique solution, an additional criterion known as maximum channel interference coefficient (CIC) was proposed. Through Monte Carlo simulations it was shown that by using QOSTBCs along with the properly selected PPM …
The exchange of emotional support with age and its relationship with emotional well-being by age.

This study tested three hypotheses derived from the application of socioemotional selectivity theory and exchange theory to the exchange of emotional support with age and its relationship with positive and negative affect by age. Data are from the Midlife in the United States study of 3,032 U.S. adults between the ages of 25 and 74. The social contact hypothesis predicts that hours of emotional support given and received should decrease with age. The exchange hypothesis predicts that the discrepancy between the hours of emotional support given and received should decrease with age to reflect more balanced exchanges with age. The goal hypothesis predicts that unequal exchanges of support should predict higher negative and lower positive affect with age. Findings supported each hypothesis. Hours of emotional support given and received decreased as chronological age increased. Although adults of all ages gave more support than they received, the discrepancy between hours of emotional support given and received became more balanced with age. Compared with equal exchanges, unequal exchanges predicted worse emotional well-being profiles only among the oldest adults in this study (i.e., those aged 55-64 and 65-74). Findings contribute to the growing literature on the changing nature of the quantity and quality of interpersonal exchanges with age.
CityFlux perfluorocarbon tracer experiments

Abstract. In June 2006, two perfluorocarbon tracer experiments were conducted in central Manchester UK as part of the CityFlux campaign. The main aim was to investigate vertical dispersion in an urban area during convective conditions, but dispersion mechanisms within the street network were also studied. Paired receptors were used in most cases where one receptor was located at ground level and one at roof level. One receptor was located on the roof of Portland Tower which is an 80 m high building in central Manchester. Source receptor distances in the two experiments varied between 120 and 600 m. The results reveal that maximum concentration was sometimes found at roof level rather than at ground level implying the effectiveness of convective forces on dispersion. The degree of vertical dispersion was found to be dependent on source receptor distance as well as on building height in proximity to the release site. Evidence of flow channelling in a street canyon was also found. Both a Gaussian profile and a street network model were applied and the results show that the urban topography may lead to highly effective flow channelling which therefore may be a very important dispersion mechanism should the right meteorological conditions prevail. The experimental results from this campaign have also been compared with a simple urban dispersion model that was developed during the DAPPLE framework and show good agreement with this. The results presented here are some of the first published regarding vertical dispersion. More tracer experiments are needed in order to further characterise vertical concentration profiles and their dependence on, for instance, atmospheric stability. The impact of urban topography on pollutant dispersion is important to focus on in future tracer experiments in order to improve performance of models as well as for our understanding of the relationship between air quality and public health.
Pemberdayaan Wanita Mendukung Strategi Gender Mainstreaming dalam Kebijakan Pembangunan Pertanian di Perdesaan

English Modernization paradigm in the implementation of agricultural development has caused various changes in rural society, namely changes in social life, culture, politic, and especially economic structure in rural areas. This phenomenon also caused trend of disintegration and discrimination in “labor division” between male and female in various fields which could potentially set aside or even eliminate the important productive function of woman. This article is aimed at the description of many thoughts and ideas (by theory) about the role and the opportunity of woman who work in agriculture and repositioning the strategy of gender mainstream within the rural agricultural development policies. The double role of women is clearly indicating the importance of the double sources of income for a household. Women potentials, either as a housewife or as an individual of agricultural worker is the important factor to determine the success of gender mainstreaming strategy. The empowerment is suggested through applied and innovative technology, protection of working woman, improvement of training and extension activities, enhancement of regulations, facility support, increasing wage rate, and household industry skill development. Job opportunity is suggested to balance between male and female and encourage woman to participate in various development activities. With this, the gender mainstreaming strategy would improve household welfare in rural areas. Indonesian Paradigma modernisasi dalam pelaksanaan pembangunan pertanian yang mengutamakan prinsip efisiensi, secara nyata telah mengakibatkan terjadinya berbagai perubahan pada masyarakat petani, baik struktur sosial, budaya dan politik terutama pada struktur ekonomi di perdesaan. Hal tersebut juga menimbulkan gejala desintegrasi dan diskriminasi dalam “pembagian kerja” antara pria dan wanita di berbagai bidang, yang dikhawatirkan dapat meminggirkan bahkan menghilangkan fungsi produksi kaum wanita. Makalah ini bertujuan mengemukakan berbagai pemikiran (teoritis) tentang peran dan peluang wanita tani, serta memposisikan kembali strategi pengarusutamaan gender (gender mainstreaming) dalam strategi kebijakan pembangunan pertanian di perdesaan. Peran ganda wanita tani membuktikan sangat penting dan strategisnya pola nafkah ganda, sebagai upaya meningkatkan pendapatan. Potensi wanita tani, sebagai isteri dan ibu rumah tangga, merupakan faktor penting penentu keberhasilan strategi pengarusutamaan gender tersebut. Pemberdayaan perlu dilakukan melalui teknologi tepat guna dan inovatif, perlindungan terhadap tenaga kerja wanita, meningkatkan efektifitas penyuluhan dan pelatihan, perbaikan regulasi, fasilitas, dan tingkat upah, pelatihan dan pembinaan ketrampilan industri rumahtangga. Kesempatan kerja agar berimbang antar gender dan mengikutsertakan mereka dalam segala kegiatan pembangunan. Pemberdayaan wanita melalui strategi pengarusutamaan jender (gender mainstreaming), untuk mewujudkan kesejahteraan rumah tangga petani di perdesaan.
Is a picture worth a thousand words? A Deep Multi-Modal Fusion Architecture for Product Classification in e-commerce

Classifying products precisely and efficiently is a major challenge in modern e-commerce. The high traffic of new products uploaded daily and the dynamic nature of the categories raise the need for machine learning models that can reduce the cost and time of human editors. In this paper, we propose a decision level fusion approach for multi-modal product classification based on text and image neural network classifiers. We train input specific state-of-the-art deep neural networks for each input source, show the potential of forging them together into a multi-modal architecture and train a novel policy network that learns to choose between them. Finally, we demonstrate that our multi-modal network improves classification accuracy over both networks on a real-world large-scale product classification dataset that we collected from Walmart.com. While we focus on image-text fusion that characterizes e-commerce businesses, our algorithms can be easily applied to other modalities such as audio, video, physical sensors, etc.
NKT Cell-TCR Expression Activates Conventional T Cells in Vivo, but Is Largely Dispensable for Mature NKT Cell Biology

Natural killer T (NKT) cell development depends on recognition of self-glycolipids via their semi-invariant Vα14i-TCR. However, to what extent TCR-mediated signals determine identity and function of mature NKT cells remains incompletely understood. To address this issue, we developed a mouse strain allowing conditional Vα14i-TCR expression from within the endogenous Tcrα locus. We demonstrate that naïve T cells are activated upon replacement of their endogenous TCR repertoire with Vα14i-restricted TCRs, but they do not differentiate into NKT cells. On the other hand, induced TCR ablation on mature NKT cells did not affect their lineage identity, homeostasis, or innate rapid cytokine secretion abilities. We therefore propose that peripheral NKT cells become unresponsive to and thus are independent of their autoreactive TCR.
Robust Grape Cluster Detection in a Vineyard by Combining the AdaBoost Framework and Multiple Color Components

The automatic fruit detection and precision picking in unstructured environments was always a difficult and frontline problem in the harvesting robots field. To realize the accurate identification of grape clusters in a vineyard, an approach for the automatic detection of ripe grape by combining the AdaBoost framework and multiple color components was developed by using a simple vision sensor. This approach mainly included three steps: (1) the dataset of classifier training samples was obtained by capturing the images from grape planting scenes using a color digital camera, extracting the effective color components for grape clusters, and then constructing the corresponding linear classification models using the threshold method; (2) based on these linear models and the dataset, a strong classifier was constructed by using the AdaBoost framework; and (3) all the pixels of the captured images were classified by the strong classifier, the noise was eliminated by the region threshold method and morphological filtering, and the grape clusters were finally marked using the enclosing rectangle method. Nine hundred testing samples were used to verify the constructed strong classifier, and the classification accuracy reached up to 96.56%, higher than other linear classification models. Moreover, 200 images captured under three different illuminations in the vineyard were selected as the testing images on which the proposed approach was applied, and the average detection rate was as high as 93.74%. The experimental results show that the approach can partly restrain the influence of the complex background such as the weather condition, leaves and changing illumination.
An Ant System Algorithm for Coloring Graphs

This paper presents an ant system algorithm for the graph coloring problem. This ant system algorithm has several new features compared to previous ant system algorithms for the coloring problem. The main idea of the algorithm is for a colony of ants to color the graph, in which ants use its knowledge about the local neighborhood, recently visited nodes, and information stored at each vertex. For proving generality of the algorithm, several instances from different categories of graphs posted on the COLOR02 Symposium web site were selected to test the algorithm. The algorithm performed well and matched the best known results for most benchmark graph instances and was close to the best known for others. The algorithm performed very well in comparison to previous heuristic algorithms for the graph coloring problem.
The role of cities: evidence from the placement of sales offices

What is the force of attraction of cities? Leading explanations include the advantages of a concentrated market and knowledge spillovers. This paper develops a model of firm location decisions in which it is possible to distinguish the importance of the concentrated-market motive from other motives, including knowledge spillovers. A key aspect of the model is that it allows for the firm to choose multiple locations. The theory is applied to study the placement of manufacturing sales offices. The implications of the concentrated-market motive are found to be a salient feature of U.S. Census micro data. The structural parameters of the model are estimated. The concentrated-market motive is found to account for approximately half of the concentration of sales offices in large cities.
