Alimentation

Pour donner une image fidèle de l’alimentation des Berbères depuis les origines et suivre son évolution il aurait fallu disposer de documents et de textes qui font malheureusement défaut, aussi plutôt que de se livrer à une étude diachronique impossible à rédiger dans l’état actuel de la recherche nous avons choisi de présenter ce que l’on sait de l’alimentation des Paléoberbères des temps préhistoriques antérieurs à l’élevage et à l’agriculture puis de regrouper nos connaissances sur l’alime..

Coercive Pressures and Anti-corruption Reporting: The Case of ASEAN Countries

This paper aims to investigate the extent of anti-corruption reporting by ASEAN companies and examine whether coercive factors influence the level of disclosure. The authors adopt indicators from the Global Reporting Initiative version 4.0 to measure the extent of anti-corruption disclosures in 117 companies’ reports. Informed by a coercive isomorphism tenet drawn from the institutional theory, the authors propose that several institutional factors influence the extent of their voluntary disclosures. The findings reveal that a large degree of variability difference between the average levels of anti-corruption disclosure in Thailand (434 words) and the Philippines (149 words). The dependence on government tenders and foreign ownership are associated with the level of disclosure. Surprisingly, the United Nation Global Compact membership is not a significant determinant of anti-corruption reporting. This signifies that the membership in the international initiative does not correspond to individual company’s commitment to disclose anti-corruption information. In spite of significant efforts undertaken by global organizations to combat corruption, the level of anti-corruption disclosure is significantly different among the four countries under study. The disclosure of sensitive information such as the confirmed incidences of corruption cases requires careful consideration by the top management as it is subjected to legal implications and reputational risks. Thus, impression management can complement the coercive pressure in explaining the level of anti-corruption reporting. This study is among the first studies which explores the association between coercive factors and the level of anti-corruption disclosure in ASEAN region

Cyclophosphamide treatment regulates the balance of functional/exhausted tumor-specific CD8(+) T cells.

An important question is how chemotherapy may (re-)activate tumor-specific immunity. In this study, we provide a phenotypic, functional and genomic analysis of tumor-specific CD8(+) T cells in tumor (P815)-bearing mice, treated or not with cyclophosphamide. Our data show that chemotherapy favors the development of effector-type lymphocytes in tumor bed, characterized by higher KLRG-1 expression, lower PD-1 expression and increased cytotoxicity. This suggests re-engagement of T lymphocytes into the effector program. IFN-I appears involved in this remodeling. Our findings provide some insight into how cyclophosphamide regulates the amplitude and quality of tumor-specific immune responses
