Diepkloof Rock Shelter offers an exceptional opportunity to study the onset and evolution of both Still Bay (SB) and Howiesons Poort (HP) techno-complexes. However, previous age estimates based on luminescence dating of burnt quartzites (Tribolo et al., 2009) and of sediments (Jacobs et al., 2008) were not in agreement. Here, we present new luminescence ages for 17 rock samples (equivalent dose estimated with a SAR-ITL protocol instead of classical MAAD-TL) as well as for 5 sediment samples (equivalent dose estimated with SAR-single grain OSL protocol) and an update of the 22 previous age estimates for burnt lithics (modified calibration and beta dose estimates). While a good agreement between the rock and sediment ages is obtained, these estimates are still significantly older than those reported by Jacobs et al. (2008). After our own analyses of the sediment from Diepkloof, it is suspected that these authors did not correctly chose the parameters for the equivalent dose determination, leading to an underestimate of the equivalent doses, and thus of the ages. From bottom to top, the mean ages are 100 ± 10 ka for stratigraphic unit (SU) Noël and 107 ± 11 ka for SU Mark (uncharacterized Lower MSA), 100 ± 10 ka for SU Lynn-Leo (Pre-SB type Lynn), 109 ± 10 ka for SUs Kim-Larry (SB), 105 ± 10 ka for SUs Kerry-Kate and 109 ± 10 ka for SU Jess (Early HP), 89 ± 8 ka for SU Jude (MSA type Jack), 77 ± 8 ka for SU John, 85 ± 9 ka for SU Fox, 83 ± 8 ka for SU Fred and 65 ± 8 ka for SU OB5 (Intermediate HP), 52 ± 5 ka for SUs OB2-4 (Late HP). This chronology, together with the technological analyses, greatly modifies the current chrono-cultural model regarding the SB and the HP and has important archaeological implications. Indeed, SB and HP no longer appear as short-lived techno-complexes with synchronous appearances for each and restricted to Oxygen Isotopic Stage (OIS) 4 across South Africa, as suggested by Jacobs et al. (2008, 2012). Rather, the sequence of Diepkloof supports a long chronology model with an early appearance of both SB and HP in the first half of OIS 5 and a long duration of the HP into OIS 3. These new dates imply that different technological traditions coexisted during OIS 5 and 4 in southern Africa and that SB and HP can no longer be considered as horizon markers.

Transgenic mice carrying a bovine alpha-lactalbumin (alpha-lac) specific ribozyme gene under the transcriptional control of the mouse mammary tumor virus long terminal repeat were generated and cross-bred with animals that highly express a bovine alpha-lac transgene (0.4 mg of alpha-lac/ml(-1) of milk). The ribozyme contains the hammerhead catalytic domain, flanked by 12-nt sequences complementary to the 3' untranslated region of bovine alpha-lac transcript. High-level expression of the ribozyme gene was detected by Northern blot analysis in the mammary gland of 7-8 day lactating transgenic mice, from 3 of 12 lines analyzed. Heterozygous expression of the ribozyme resulted in a reduction in the levels of the target mRNA to 78, 58, and 50% of that observed in the nonribozyme transgenic littermate controls for three independent lines. The ribozyme-mediated reduction in the levels of the bovine protein paralleled that observed for the mRNA, and was positively correlated with the level of expression of the ribozyme. In nonribozyme expressing transgenic mice, the level of bovine alpha-lac mRNA and protein was not affected. The specificity of this activity is demonstrated by the absence of a reduction in the levels of the endogenous murine alpha-lac mRNA or protein. These results demonstrate the feasibility of ribozyme-mediated down-regulation of highly-expressed transcripts in transgenic animals.

In this study I examine the development of three inclusive music bands in Cork city. Derived from Jellison’s research on inclusive music education, inclusive music bands involve students with disabilities coming together with typically developing peers to make and learn music that is meaningful (Jellison, 2012). As part of this study, I established three inclusive music bands to address the lack of inclusive music making and learning experiences in Cork city. Each of these bands evolved and adapted in order to be socio-culturally relevant within formal and informal settings: Circles (community education band), Till 4 (secondary school band) and Mish Mash (third level and community band). I integrated Digital Musical Instruments into the three bands, in order to ensure access to music making and learning for band members with profound physical disabilities. Digital Musical Instruments are electronic music devices that facilitate active music making with minimal movement. This is the first study in Ireland to examine the experiences of inclusive music making and learning using Digital Musical Instruments. I propose that the integration of Digital Musical Instruments into inclusive music bands has the potential to further the equality and social justice agenda in music education in Ireland. In this study, I employed qualitative research methodology, incorporating participatory action research methodology and case study design. In this thesis I reveal the experiences of being involved in an inclusive music band in Cork city. I particularly focus on examining whether the use of this technology enhances meaningful music making and learning experiences for members with disabilities within inclusive environments. To both inform and understand the person centered and adaptable nature of these inclusive bands, I draw theoretical insights from Sen’s Capabilities Approach and Deleuze and Guatarri’s Rhizome Theory. Supported by descriptive narrative from research participants and an indepth examination of literature, I discover the optimum conditions and associated challenges of inclusive music practice in Cork city.

This paper analyses how the topic of the silent statue is dealt with in Neo-Latin literature. The subject matter comes from the epigrams about Pythagoras of the Palatine Anthology. There are numerous Neo-Latin imitations of this topic that are complex as various sources are used at the same time. The authors focus on an active reading of the epigrams of their predecessors, applying the traditional motive to new subjects and adapting it to the religious theme.

Ernest Mercier est l’un des patrons les plus influents de l'entre-deux-guerres en France. Ses différentes activités industrielles l'ont conduit à siéger sur de vastes pans de l’économie française, notamment du secteur énergétique. La thèse retrace la carrière pétrolière d'un homme qui a joué un rôle central pour le développement d'une industrie devenue stratégique, mais qui est embryonnaire lorsqu'il rejoint ce secteur après la Première Guerre mondiale. Mercier assiste et assure la création d'une industrie pétrolière nationale. Les obstacles se font légion contre les ambitions pétrolières de la France. Elle se présente bien tard sur un marché étroitement contrôlé par de puissants trusts. La recherche et l'exploitation pétrolière demandent d'importantes ressources, et aucune société française n'a les moyens d'une politique indépendante. Certaines banques se lancent alors dans les affaires de pétrole en s'alliant aux grands trusts internationaux. C'est le cas de Paribas; la gestion de ses avoirs roumains représente la première expérience de Mercier dans ce secteur. L'État s'intéresse aussi au pétrole, il devient un acteur incontournable. Le gouvernement français n'a pourtant pas les moyens de ses ambitions dans le domaine pétrolier. La politique nationale mise en place durant l'entre-deux-guerres doit faire appel à l'épargne privée française. La création d'une compagnie nationale, la Compagnie française des pétroles, en 1924 regroupe ainsi les différentes banques et sociétés intéressées au pétrole. Mercier est personnellement choisi par le président Raymond Poincaré pour mener à bien cette mission. Cette carrière s'articule donc autour d'un fragile équilibre entre milieux privés et gouvernement. Mercier devient rapidement l'intermédiaire incontournable qui régit ces relations. La thèse s'appuie sur les archives bancaires et industrielles, mais aussi sur celles du gouvernement français et de ses différents ministères. Cette analyse de la carrière d'Ernest Mercier permet de retracer les origines du secteur pétrolier français et l'action déterminante d'un homme. Elle expose les mécanismes d'influence d'une puissante banque d'affaires et les conflits d'intérêts qu'engendre l'exploitation pétrolière.
