Rôle et évolution du rôle logistique des lixae dans les armées romaines

Cette recherche a pour but d’éclaircir le rôle logistique des lixae dans les armées romaines et l’évolution de celui-ci entre la fin de la période républicaine et de l’Empire tardif. Bien que ceux-ci soient souvent associés aux vivandiers et aux valets d’armée, leur présence dans les armées ne se limite pas à ces deux rôles. Aussi, il sera d’abord question du contexte civil dans les armées romaines en rapport avec les lixae. L’étymologie et l’historiographie des lixae seront ensuite traitées avant d’entreprendre la description et l’analyse de leurs différents rôles d’après les sources anciennes. La dernière partie de cette recherche sera consacrée aux différents rôles des lixae dans les armées romaines et à leur évolution à travers le temps. L’hypothèse avancée dans la recherche est celle d’une spécialisation du rôle marchand des lixae dans les armées entre la période républicaine et la période du haut empire et de l’empire tardif.

(Table 1) Strontium isotopic ratios of interstitial waters from ODP Leg 125 holes

The strontium isotopic data presented here are from interstitial waters squeezed from unconsolidated serpentine, an unusual type of substrate that was recovered from Mariana and Bonin forearc seamounts and has not been previously drilled by the Deep Sea Drilling Project or Ocean Drilling Program. The texture and composition of some of these serpentine deposits from Conical Seamount, located on the Mariana forearc, indicate emplacement as low- or high-viscosity, cold gravitational flows, which are therefore neither sediment nor igneous rock. The strontium isotopic ratios of the interstitial waters from the unconsolidated serpentine range from 0.70912 to 0.70525 and trend toward a relatively less radiogenic composition with increasing sub-bottom depth. These strontium isotopic ratios are derived from at least two strontium sources: seawater and igneous. The strontium isotopic gradients from the interstitial waters from the Leg 125 sites are probably the result of diffusive transport of strontium from an igneous source deep within the lithosphere that may be contaminated with subducted or underplated sediment.

El impacto de la crisis en la industria cinematográfica en Europa

Este trabajo analiza el impacto que ha generado la crisis económica y financiera más reciente en las industrias cinematográficas de siete países miembros de la Unión Europea. Las conclusiones señalan que, en efecto, la crisis ha impactado negativamente en las industrias de España e Italia, y muy gravemente en la de Portugal, pero en el lado contrario, la del Reino Unido ha experimentado un crecimiento apreciable y las de Francia y Alemania también lo han hecho, aunque en menor medida. Y en segundo lugar, es muy notable la escasa colaboración alcanzada entre los agentes europeos.

Branding Hotels

[Excerpt] The hotel business has become a business of brands. Price Waterhouse Coopers estimates that there are over 300 hotel brands today with no one brand dominating the market. Every major brand management issue (brand extensions, global brand expansion, re-branding, un-branding, co-branding, brand portfolio development, brand acquisitions, new brand development, etc.) is being explored. An understanding of the competitive context and intra-and inter-brand dynamics will help owners, operators, asset managers, suppliers and litigators, as well as new entrants into the business make better and more informed brand management decisions.

La relation rendement en dividendes - risque

Ce mémoire présente une version dividende du Capital Asset Pricing Model (CAPM). Selon le modèle développé ici, il existe une relation à l'équilibre entre le rendement en dividendes et le risque systématique. Cette relation est linéaire et négative et peut-être dérivée dans un monde avec ou sans impôt. Une application de ce modèle est possible lorsqu'on évalue la valeur théorique d'une action ordinaire à l'aide du taux net d'actualisation. Au total, le test empirique indique qu'il y a une concordance observable entre les implications majeures du modèle et les faits.

Consequences of big data on the individual: Interview

The speed with which data has moved from being scarce, expensive and valuable, thus justifying detailed and careful verification and analysis to a situation where the streams of detailed data are almost too large to handle has caused a series of shifts to occur. Legal systems already have severe problems keeping up with, or even in touch with, the rate at which unexpected outcomes flow from information technology. The capacity to harness massive quantities of existing data has driven Big Data applications until recently. Now the data flows in real time are rising swiftly, become more invasive and offer monitoring potential that is eagerly sought by commerce and government alike. The ambiguities as to who own this often quite remarkably intrusive personal data need to be resolved – and rapidly - but are likely to encounter rising resistance from industrial and commercial bodies who see this data flow as ‘theirs’. There have been many changes in ICT that has led to stresses in the resolution of the conflicts between IP exploiters and their customers, but this one is of a different scale due to the wide potential for individual customisation of pricing, identification and the rising commercial value of integrated streams of diverse personal data. A new reconciliation between the parties involved is needed. New business models, and a shift in the current confusions over who owns what data into alignments that are in better accord with the community expectations. After all they are the customers, and the emergence of information monopolies needs to be balanced by appropriate consumer/subject rights. This will be a difficult discussion, but one that is needed to realise the great benefits to all that are clearly available if these issues can be positively resolved. The customers need to make these data flow contestable in some form. These Big data flows are only going to grow and become ever more instructive. A better balance is necessary, For the first time these changes are directly affecting governance of democracies, as the very effective micro targeting tools deployed in recent elections have shown. Yet the data gathered is not available to the subjects. This is not a survivable social model. The Private Data Commons needs our help. Businesses and governments exploit big data without regard for issues of legality, data quality, disparate data meanings, and process quality. This often results in poor decisions, with individuals bearing the greatest risk. The threats harbored by big data extend far beyond the individual, however, and call for new legal structures, business processes, and concepts such as a Private Data Commons. This Web extra is the audio part of a video in which author Marcus Wigan expands on his article "Big Data's Big Unintended Consequences" and discusses how businesses and governments exploit big data without regard for issues of legality, data quality, disparate data meanings, and process quality. This often results in poor decisions, with individuals bearing the greatest risk. The threats harbored by big data extend far beyond the individual, however, and call for new legal structures, business processes, and concepts such as a Private Data Commons.

New Foods, New Consumers: Innovation in Food Product Development

BACKGROUND: Today, new lifestyles, higher incomes and consumer awareness are creating consumer demand for a year-round supply of high-quality, diverse and innovative food products. However, when it comes to innovation, the food sector is less changeable when compared to other sectors, such as high technology. Still, in the past decades much and important developments have been achieved in several areas related to foods and the food industry. METHODS: A systematic review of scientific literature was conducted on Science Direct. The topics investigated were: aspects related to innovation in food development (such as the transfer of innovation, open innovation, collaborative innovation and consumer perception and its role in the developing process); the innovation in the food industry (particularly regarding the processing technologies and packaging, which are two prominent areas of innovation in this sector nowadays); the innovation in the cooking sector (particularly in regards to the molecular gastronomy and science based cooking). RESULTS: A total of 146 articles were included in the review and the aspects focused allowed confirming that innovation has been recognized as a key driver of economic growth. Within the framework of ‘open innovation’, a number of key issues related to the acquisition of external knowledge in food technology must be taken into consideration. Food product development is highly dependent on the consumer perception and acceptance, and hence it is of utmost importance to include the consumer in the development process to minimize failure probabilities. The sectors of the food industry where important developments and innovation are registered include the processing technologies and the packaging systems, where the latest progresses have produced very significant outcomes. CONCLUSION: The present work allowed verifying the latest improvements and trend towards food product development from two perspectives, the product itself and the industrial processing. This sector is undoubtedly a major key for the success and competitiveness nowadays in the food industry.

As relações bi-unívocas entre a liderança e a cultura organizacional num serviço de imagiologia

Este estudo assenta nas relações entre liderança e cultura organizacional num serviço de imagiologia, entendendo-se, assim, que o papel do líder é fundamental para a orientação e o desenvolvimento do trabalho, através de condutas e estratégias que se adaptem às diversas situações. Deste modo, achou-se pertinente perceber o conceito de liderança, as suas abordagens teóricas e o modo como este conceito poderá ser posto em prática ao nível das instituições, contribuindo para fortalecer a comunicação e a cultura organizacional. No que respeita à cultura organizacional, esta resume-se a um conjunto de normas e comportamentos, os quais são utilizados pelas pessoas de forma a interagirem numa organização. Outra questão fundamental passa pela comunicação no seio da cultura organizacional, sendo um factor de extrema relevância, no que respeita à estrutura na sociedade e no funcionamento das organizações. Distinguem-se dois tipos de comunicação: a formal, uma comunicação sistemática; e a informal, uma comunicação assistemática. Em resumo, conclui-se que a liderança, movida pela comunicação, se trata de um processo em que as atitudes e os comportamentos dos líderes, bem como dos seus seguidores, incidem sobre a sua eficácia, a qual está, igualmente, dependente do contexto da cultura organizacional. ABSTRACT: This study builds on the relationship between leadership and organizational culture in a department of imaging, it being understood that, the role of leader is crucial to the direction and development of work, through pipelines and strategies that adapt to different situations. Thus, it is thought appropriate understand the concept of leadership, their theoretical approaches and how this concept could be implemented within the institutions, helping to strengthen communication and organizational culture. Regarding the organizational culture, this boils down to a number of norms and behaviours, which are used by people in order to interact in an organization. lt is assumed as a system of values, expressed through rituals, myths, beliefs and habits common to members of a particular institution, which produces widely accepted norms of behaviour by the group. Another key issue is through communication within the organizational culture, being a factor of extreme importance, with regard to the structure in society and the functioning of organizations. There are two types of communication: the formal, a systematic communication, and informally, a communications patchy. lt is through communication that are solved most problems, and is used to exploit many opportunities, managing organizational balanced life. ln summary, it appears that leadership, driven by communication, this is a process in which the attitudes and behaviours of leaders and their followers, focusing on its effectiveness, which is also dependent on context the organizational culture.
