Authors: Guo Wei , Fang Zhijie , Li Hongliang , Liu Yanan
Published: April 2014

24(28)-Methylene-1α-hydroxyvitamin D3 was synthesised in 13 steps from vitamin D2. The key step of the synthesis involved the Wittig–Horner olefination of a nor-vitamin D2 aldehyde with diethylphosphono-3-methyl-2-butanone. The resulting enone was followed by reduced methylenation, photoisomerisation and deprotection then gave the target compound.
Dying German in Ghana: The Basel Mission Wrestles with Grief, 1830–1918
Authors: Grant Paul
Published: April 2014

Throughout the eighty years preceding the First World War, the Basel Mission's activities in the Gold Coast were overshadowed by endless reports of missionary death and disease. Lengthy bouts of sickness and grief described the very context of mission work. With each turn in the road, the missionaries and the home office alike turned to writing and rewriting their history, and in the process incorporated death into the message of the mission: sacrifice with an assurance of ultimate accomplishment gave way to notions of sacrifice as service in itself. This conversation was profoundly emotional and frequently expressed itself in song and poetry – the field hymnal, for example, included several songs for death and sickness. At the centre of Basel Mission grief lay a particularly German notion of home and spatial belonging called Heimat. To these German missionaries, including their supporters in Europe, the tragedy of dying in the mission field was above all dying far away from home.

Published: April 2014

The current state-of-the-art of variable stiffness actuators consists mostly of different concepts for single-degree of freedom joints. However, in bio-inspired robotic applications, multiple degrees of freedom variable stiffness actuators are often desired. Currently, this is usually achieved by cascading single-degree of freedom actuators. The innovation presented in this work is a two-degree of freedom variable stiffness actuator using the mechanically adjustable and controllable equilibrium position actuator (MACCEPA) concept. The presented actuator is not a cascade of two single-degree of freedom actuators, but centralizes the two degrees of freedom in one single joint. Equilibrium position and stiffness of the actuator are, furthermore, independently controllable in both degrees of freedom. The design and experimental validation of the actuator are discussed in this work. The independence of adjusting the equilibrium position and stiffness of the actuator are experimentally validated. The results show that the measured characteristics of the actuator sufficiently match the theoretically calculated ones. Future work includes implementing the presented two-degree of freedom actuator in an application, like a bipedal robot or a robotic arm.
Directional Scattering of Semiconductor Nanoparticles Embedded in a Liquid Crystal
Authors: García-Cámara Braulio , Algorri José , Urruchi Virginia , Sánchez-Pena José
Published: April 2014

Light scattering by semiconductor nanoparticles has been shown to be more complex than was believed until now. Both electric and magnetic responses emerge in the visible range. In addition, directional effects on light scattering of these nanoparticles were recently obtained. In particular, zero backward and minimum-forward scattering are observed. These phenomena are very interesting for several applications such as, for instance, optical switches or modulators. The strong dependence of these phenomena on the properties of both the particle and the surrounding medium can be used to tune them. The electrical control on the optical properties of liquid crystals could be used to control the directional effects of embedded semiconductor nanoparticles. In this work, we theoretically analyze the effects on the directional distribution of light scattering by these particles when the refractive index of a surrounded liquid crystal changes from the ordinary to the extraordinary configuration. Several semiconductor materials and liquid crystals are studied in order to optimize the contrast between the two states.
« Devenir soi-même » par la lecture collective. Une approche anti-individualiste
Authors: Albenga Viviane
Published: April 2014

de vista anti-individualista. Todos los lectores no pertenecen a familias de lectores, pero todos consideran la lectura como una manera de recomponer las identidades sociales, es decir «reafiliarse». Por consiguiente, entrar en un grupo de lectura significa integrar un grupo de pares culturales con los cuales es posible desarrollar el cuidado de sí mismo. Según Michel Foucault, el cuidado de sí necesita el de los otros. Lo actualizan la escritura y la puesta en escena de sí mismo a partir de las lecturas. Finalmente, la lectura cobra un sentido emancipatorio para las lectoras más que para los lectores, por permitir la ampliación de sus posibilidades, de manera tan práctica como simbólica.
Le procès des Fleurs du mal mis en scène par des juristes : lectures en conflits
Authors: Labbé Mathilde
Published: April 2014

This paper is based on a comparison between two adaptations for the stage of the trial against Baudelaire’s The Flowers of Evil. These adaptations took place in a specific professional context : Le Proces des Fleurs du Mal by Philippe Blondeau, first staged in 2006, and Outrage by Olivier Treiner, staged in 2008, were written and performed by professionals from the legal system. The study of these plays : their staging is meant to show that the ethical and aesthetic way of looking at texts played two different roles in this process. Although the two interpretive communities that made these plays meaningful are mostly built on an interest in literature and theater, they planned on appealing to the audience through a reflection on the profession’s ethics and on implicit references to recent juridical controversies. After they had temporarily put aside their professional identity in order to assume an artistic one, the authors and actors finally seemed to go back to this first identification in the way they address the spectators.

Authors: Chatys Rafał , Malcho Milan , Orman Łukasz J.
Published: April 2014

The paper presents the results of boiling heat transfer enhancement due to the application of additional mesh on the heat exchanger surface. The copper mesh of porosity of 75% was sintered to the copper heater producing strong bonds between the elements. The results indicate a possibility of significant improvement of heat transfer conditions in comparison to the smooth surface. The heat flux was found to be almost six times higher for the same superheat if the mesh structure was applied. Distilled water and ethanol were the working fluids. The investigations were performed under atmospheric pressure.

Les dépenses culturelles des collectivités territoriales en 2010 : 7,6 milliards d'euros pour la culture
Authors: Delvainquière Jean-Cédric , Tugores François , Laroche Nicolas , Jourdan Benoît
Published: April 2014

En 2010, les dépenses culturelles des collectivités territoriales (régions, départements, communes de plus de 10 000 habitants et leurs groupements, dom compris) se sont élevées à 7,6 milliards d’euros soit 118 euros par habitant. Les communes et leurs groupements assument près des trois quarts (73 %) de ces dépenses (respectivement 4,6 milliards et 1 milliard d’euros), les départements 18 % (soit 1,4 milliard) et les régions 9 % (0,7 milliard). Ces dépenses représentent en moyenne une part plus élevée des dépenses totales des communes et de leurs groupements (8,0 % et 7,0 %) que de celles des régions (2,7?%) et des départements (2,1 %). Par rapport à 2006, année de la précédente édition de l’enquête, les dépenses culturelles territoriales ont progressé de près de 10 % soit +?2,3 % par an en France métropolitaine. Progressant quasiment au même rythme que l’inflation (+?1,4 % par an), les dépenses culturelles des communes ont plutôt stagné en volume, mais le nombre de groupements de communes actifs dans le domaine culturel a progressé et leurs dépenses culturelles ont augmenté de 6 % par an. L’évolution des dépenses culturelles des départements et des régions est légèrement supérieure à l’inflation pour les départements (+?1,8% par an), plus significative pour les régions (+?4,5 % par an) et tient surtout à une forte progression en début de période. L’effort culturel des départements et des régions s’est ensuite contracté en raison d’une plus forte progression des dépenses totales, liée aux transferts de compétences. Le soutien à l’expression artistique et aux activités culturelles regroupe près de 60 % des dépenses des communes et de leurs groupements (4,3 milliards d’euros), en grande partie des dépenses de fonctionnement (85 %). Départements et régions se sont investis de manière croissante dans le patrimoine, qui représente 59 % des dépenses culturelles départementales et 23 % des dépenses culturelles régionales en 2010. Plus impliqué dans la gestion souvent directe de services et d’équipements culturels de proximité (bibliothèques, conservatoires et écoles d’art, musées, etc.), le bloc communal consacre plus de la moitié de ses dépenses culturelles de fonctionnement à la rémunération des personnels, pour près de 2,5 milliards d’euros. Ce sont toutefois les subventions culturelles de fonctionnement qui ont le plus progressé (+?5 % par an pour les communes métropolitaines entre 2006 et 2010), en particulier au bénéfice des théâtres et des arts plastiques. À l’inverse, les subventions représentent plus de 80 % des dépenses culturelles des régions. Elles soutiennent, pour leur fonctionnement, des bénéficiaires de droit privé, notamment associatifs, et l’effort d’investissement culturel des communes et de leurs groupements.
Auto-analyse et « relation en double » : à propos de la correspondance entre S. Freud et W. Fliess
Authors: Jung Johann
Published: April 2014

Temps fort de l’auto-analyse, la correspondance entre Freud et Fliess permet de suivre pas à pas les étapes du processus auto-organisateur qui aboutira aux grandes découvertes de la psychanalyse. L’adresse à un « autre soi-même », absent mais néanmoins convoqué psychiquement, révèle aussi la nature du lien en double qui unit les deux hommes ; Fliess fait figure en effet d’interlocuteur privilégié, de « double transitionnel », support à partir duquel Freud parvient à renouer un dialogue interne où il puisera sa créativité. Cette « amitié nécessaire » qui durera près de 17 ans témoigne d’une profonde transformation du « rapport à soi » de Freud. L’analyse de ce transfert amoureux l’amènera finalement à reprendre à son propre compte, dans un mouvement réflexif, ce qui jusqu’alors était adressé à son « unique public ».
Social Networks and Employee Knowledge Sharing and Performance
Authors: Peng Jianping , Quan Jing ("Jim")
Published: April 2014

In this chapter, the authors investigate the correlation between characteristics of the four social networks and employee task and contextual performance. The chapter focuses on the degree centrality and betweenness centrality of the four social networks (Job Advisory, Work Discussion, Friendship and Email Networks) of a Chinese state-owned enterprise as well as the individual attributes of knowledge sharing behavior and IT capability. The findings of this research are 1) employee contextual performance is uncorrelated with the network characteristics; 2) it is significantly and positively correlated with knowledge sharing behavior, but significantly and negatively correlated with individual IT capability, and 3) task performance is correlated, both positively and negatively, with various network characteristics, but not with knowledge sharing behavior and individual IT capability. In addition to discussing the cultural dimension of these results, the authors draw theoretical and managerial implications based on our research framework and findings.
One Year Forward
Authors: Hutter James
Published: April 2014

With the prevalence of affordable e-Readers in the consumer marketplace and library users increasingly having access to lendable e-Books from their local library institutions, library administrators continue to have difficulty in determining the immediate and long term effect of these technologies on their organizations. This chapter attempts to provide administrators with a brief overview of the current e-Reader and e-Book technology landscape and describe trends and issues. To help Administrators better understand their library users' experiences and expectations with e-Readers and e-Books, the researcher conducted a survey of 70 individuals. This survey is a follow-up to 2012's E-Readers and E-Books in Public Libraries: Measuring Library Patron Expectations research project. Using the same survey questions, format and potential respondent pool, One Year Forward demonstrates that patrons are increasingly demanding access to e-Books and e-Readers. Library patrons are finding these services more easy to use than in the past. Users clearly see value in these services both now and in the future. The results of this research project should be difficult for any library administrator to ignore.
The Impact of the Relationship between Gardner's Multiple Intelligence and Kolb's Learning Style
Authors: Neo Tse-Kian , Sabbaghan Sahar
Published: April 2014

In a diverse work environment, it is important to have diverse leaders, managers, and people with different talents and intelligence in order to deal with different problems. In this case, each individual can know their own strength and weakness, and know which position works best for them. The concept of learning styles is used to describe individual differences in the way people learn. According to Kolb (1984), each person has a unique way to absorb and process experiences and information. He has identified four statistically prevalent learning styles- diverging, assimilating, converging, and accommodating. On the other hand, Gardner's Multiple Intelligence Theory is very helpful to recognize that people have differing aptitude in different subject areas. This chapter documents a study in which the participants consisted of 153 bachelor students of Management from the Multimedia University of Malaysia. They were given two questionnaires, one for Kolb's learning style and other for Gardner's Multiple Intelligence inventory and a correlation was conducted. The results showed that there was a significant relationship between Kolb's Learning Style and Multiple Intelligence. The relationship could be seen particularly in Abstract Conceptualization (AC) and Multiple Intelligences which were Nature, kinesthetic, music, word, interpersonal, and picture. The results also indicated that the majority of the participants are between AC and AE which means they are convergers. Having the right information for companies can be beneficial since knowing how their employees learn can lead to a diverse workplace that would have significant results on organizational structure, planning, development, and operation.
Argument Extraction in Opinion Analysis
Authors: Garcia-Villalba Maria Paz , Saint-Dizier Patrick
Published: April 2014

In this chapter, the authors present foundational elements related to argument extraction in opinion texts to design a model of how consumers develop argumentation in such texts. A second goal of the chapter is to analyze and synthesize user preferences and therefore user value systems from these arguments. The authors show that (1) that the association of an evaluative expression with a discourse structure such as an elaboration, an illustration, or a reformulation must be interpreted as an argument and (2) that the link between a consumer statement and a related argument often requires domain knowledge and dedicated inference schemas. This chapter develops a conceptual semantics of these discourse structures.
Digital Resources and Approaches Adopted by User-Centred Museums
Authors: Solima Ludovico
Published: April 2014

Society is experiencing unprecedented changes, largely attributable to the evolution of communication technologies, which are steadily reframing our way of life, and the methods we use to establish and maintain social relations. Museums are therefore facing numerous challenges, in general as a result of these developments: apps, open content, and the Internet-of-things. A complex relationship can be created between visitors and the museum, and this also opens new unexplored opportunities for user involvement in the museum's activities, even during the course of the visit itself. It is worth taking care to identify all the variables involved in the museum-visitor-relationship, which also encompasses the social dimension. Both the museum and the individual are active participants in a gradually expanding relationship, namely the growth of the so-called Web 2.0 and social media. Therefore, we can assume the need for museums to develop a conscious strategy for their social media presence, a real social media strategy, which forms part of the museum's wider digital strategy. The increasingly pervasive spread of e-mobile technology is a foretaste of the moment when museumgoers will radically change both the way of establishing relations with these organisations and the actual ways of using museum services. This chapter focuses on digital resources and approaches adopted by user-centred museums, where there is an increasing impact from the internet and social media.
From Accounting to Accountability at the Virtual Museums in Pompeii and Herculaneum
Authors: Esposito Paolo
Published: April 2014

The enhancement of artistic and cultural heritage has been a recurring theme within the scientific and cultural debate by scholars from different disciplines and in the political agenda of most countries over the last decades (Senese, 2002; Meneguzzo & Grossi, 2002; Ferri & Zan, 2012). During the early 90s, researchers focused their attention on management practices, tools and models referring to arts and cultural organizations (Peacock, 1982; Frey, 1994; Towse, 1997; Christiansen & Skaerbaeck, 1997; Zan, 2002), as well as on the development of new and different organizational forms under pressure from the New Public Management (Pollitt, 2001; Lapsley, 2008; Ferri & Zan, 2012; Lindqvist, 2012). These studies aimed at analyzing, developing and proposing different conceptual and management frameworks within a context characterized by increasing scarcity of financial resources in addition to regulatory complexity. The purpose of this chapter is to provide an analysis of the growing phenomenon represented by the “Virtual Musealization” of archaeological sites in Italy, focusing on the case of Pompeii and Herculaneum.
The Disability Marketing and the Cultural “Product”
Authors: Migliaccio Guido
Published: April 2014

Differences among people have to be considered as an opportunity, even in the field of economy. This would contribute to socially and professionally enhance the condition of people with disabilities. Due to an increase in life expectancy and medical advances, there are currently many people with disabilities. Disability creates significant burdens for public expenditure and for private enterprises including people with disabilities in their staff. Disability management facilitates the inclusion of people with disabilities in the production system, by considering diversity as an opportunity. There have been significant initiatives from museums and other cultural institutions, as well as publishing houses. Studies on this subject should therefore multiply in order to encourage the development of specific opportunity/cost measurement standards regarding the inclusion of disabled people in working processes and investments on products that, planned for all, favor disabled and non-disabled. In this new context, the education and culture of people with disabilities play a crucial role. In this chapter, the author focuses on the Italian experience which is assumed to be useful in broader contexts.

Published: April 2014

In a condom sorting process, we need to shoot the state image of condom through the camera and do the ellipse detection to determine the front position of condom on the conveyor belt, so developing the image processing algorithms which can detect the condom ring is necessary. The algorithm based on the Hough circle detection can obtain better detection effect for the most forms of the condom ring position, but it can not correctly detect the circle when the image shows linear shape; the algorithm based on the contrast of the ring detection get better effect on the ring in the image showing linear, while it has a low recognition rate in more folded case. We combined the two algorithms to use, proposed a combined algorithm which overcame the respective shortcomings of the two algorithms. Verified by experiment, the results of detection, recognition rate and the average processing time show the combined algorithms get the best comprehensive effect.

Authors: Wang Xiang , Zheng Yuan
Published: April 2014

Fault diagnosis is essentially a kind of pattern recognition. In this paper propose a novel machinery fault diagnosis method based on supervised locally linear embedding is proposed first. The approach first performs the recently proposed manifold learning algorithm locally linear embedding on the high-dimensional fault signal samples to learn the intrinsic embedded multiple manifold features corresponding to different fault modes. Supervised locally linear embedding not only can map them into a low-dimensional embedded space to achieve fault feature extraction, but also can deal with new fault samples. Finally fault classification is carried out in the embedded manifold space. The ball bearing fault signals are used to validate the proposed fault diagnosis method. The results indicate that the proposed approach obviously improves the fault classification performance and outperforms the other traditional approaches.
