The Genua brothers: a family at the crossroads

Managing the family business is a timely and thought provoking book that should encourage greater debate about where family businesses are going and what issues are paramount. The editors have made a consious attempt to invite and encourage academic and industry practitioners to contribute chapters.

Are youth mentoring programs good value-for-money? An evaluation of the Big Brothers Big Sisters Melbourne program

Background : The Big Brothers Big Sisters (BBBS) program matches vulnerable young people with a trained, supervised adult volunteer as mentor. The young people are typically seriously disadvantaged, with multiple psychosocial problems.

Methods : Threshold analysis was undertaken to determine whether investment in the program was a worthwhile use of limited public funds. The potential cost savings were based on US estimates of life-time costs associated with high-risk youth who drop out-of-school and become adult criminals. The intervention was modelled for children aged 10–14 years residing in Melbourne in 2004.

Results : If the program serviced 2,208 of the most vulnerable young people, it would cost AUD 39.5 M. Assuming 50% were high-risk, the associated costs of their adult criminality would be AUD 3.3 billion. To break even, the program would need to avert high-risk behaviours in only 1.3% (14/1,104) of participants.

Conclusion : This indicative evaluation suggests that the BBBS program represents excellent 'value for money'.

Continuity and change at C.B.C. : an ethnography of a Catholic Brothers School in Australian society

This thesis is an ethnographic investigation of a Catholic Brothers school, Christian Brothers College (C.B.C.), in the provincial city of Newburyport, Australia* The study explores the traditions and historical purposes of education at the independent, religious school, and examines the manner in which these have changed or are changing. All names, including the name of the school and the city, have been altered to preserve anonymity. The opening section discusses the emergence of the theoretical problem of the dialectic of change and continuity in the ongoing activity of C.B.C. actors. This is followed by an argument that an understanding of such activity requires an ethnographic perspective. Such a perspective, however, must not overlook the organisational and structural constraints within which participants operate. Hence, a critical ethnography, which takes account of both the agency of human actors and the structures which influence their activity, is advocated as the most suitable approach for understanding continuity and change within a complex organisation in its social context. This argument is followed by an ethnographic account of Christian Brothers College, which focuses on the perceptions and activities of teachers and administrators, Individual chapters deal with the Christian Brothers Order and its educational mission at C.B.C.; the nature of religious education at the school; the administration of the school; approaches to control and discipline; the curriculum and evaluation of pupils; and the relationship between C.B.C. and the wider Newburyport community. The concluding section integrates an analysis of continuity and change at C.B.C. with a discussion of theoretical perspectives on reproduction and transformation. The thesis concludes that, although change has occurred in many ways, an institutionalised image of C.B.C. as 'Brothers’ school'persists and impedes the formation of more democratic authority relations, curriculum, and evaluation. The potential for such change, however, is seen most strongly in the ongoing reform of religious education.

Systemic activation of dendritic cells by toll-like receptor ligands or malaria infection impairs cross-presentation and antiviral immunity

The mechanisms responsible for the immunosuppression associated with sepsis or some chronic blood infections remain poorly understood. Here we show that infection with a malaria parasite (Plasmodium berghei) or simple systemic exposure to bacterial or viral Toll-like receptor ligands inhibited cross-priming. Reduced cross-priming was a consequence of downregulation of cross-presentation by activated dendritic cells due to systemic activation that did not otherwise globally inhibit T cell proliferation. Although activated dendritic cells retained their capacity to present viral antigens via the endogenous major histocompatibility complex class I processing pathway, antiviral responses were greatly impaired in mice exposed to Toll-like receptor ligands. This is consistent with a key function for cross-presentation in antiviral immunity and helps explain the immunosuppressive effects of systemic infection. Moreover, inhibition of cross-presentation was overcome by injection of dendritic cells bearing antigen, which provides a new strategy for generating immunity during immunosuppressive blood infections.

Toll like receptors play a role in general immunity, eye infection and inflammation : TLRs for nanodelivery

Dendritic cells [DCs] are potent antigen presenting cells [APC], which plays a vital role in immune system by detecting and capturing pathogens in the body. DCs perform a pivotal role in induction of T cell response. Regulation of immune response can be achieved by specific antigen [Ag] delivery to DCs. A delivery system that can efficiently target and present Ags to DCs for the purpose of anti-tumour activity is currently a topic of significant research interest. DCs are receiving attention due to their key role in anti cancer host response and due to their adjuvanic property in tumour vaccines. Role of toll like receptors [TLR] in innate immune system and their part in eventual stimulation of adaptive immunity is exploited to develop vaccines. TLR agonists in conjugation with vaccines are shown to increase therapeutic efficacy in some cases. TLRs also play a vital role in protecting the cornea from invading pathogens. Due to adverse effects in the treatment of ocular inflammations, cancer and in viral infections, an alternate approach such as the use of TLRs will solve the inquisitive question regarding side effects. The intended delivery is attained by the use of nanoparticles which in turn leads to prolonged half-life in the body. Co-delivery of Ags, TLRs and immunomodulators using nanoparticles has been demonstrated to elicit potent cellular immune responses and are currently under development of clinically applicable immunisations and vaccines.

Sex differences in the Toll-like receptor-mediated response of plasmacytoid dendritic cells to HIV-1

Manifestations of viral infections can differ between women and men, and marked sex differences have been described in the course of HIV-1 disease. HIV-1-infected women tend to have lower viral loads early in HIV-1 infection but progress faster to AIDS for a given viral load than men. Here we show substantial sex differences in the response of plasmacytoid dendritic cells (pDCs) to HIV-1. pDCs derived from women produce markedly more interferon-alpha (IFN-alpha) in response to HIV-1-encoded Toll-like receptor 7 (TLR7) ligands than pDCs derived from men, resulting in stronger secondary activation of CD8(+) T cells. In line with these in vitro studies, treatment-naive women chronically infected with HIV-1 had considerably higher levels of CD8(+) T cell activation than men after adjusting for viral load. These data show that sex differences in TLR-mediated activation of pDCs may account for higher immune activation in women compared to men at a given HIV-1 viral load and provide a mechanism by which the same level of viral replication might result in faster HIV-1 disease progression in women compared to men. Modulation of the TLR7 pathway in pDCs may therefore represent a new approach to reduce HIV-1-associated pathology.

The effect of the Lehman Brothers bankruptcy on the performance of Chinese sectors

We investigate the effect of the news announcement of the Lehman Brothers (LBs) bankruptcy on the performance of Shanghai Stock Exchange (SSE) sectors. Unlike the assumption in the literature that firms are homogenous, we address the unknown issue: Does LBs bankruptcy have a heterogeneous effect on stock returns of sectors listed on SSE? We find statistically insignificant effect of LBs bankruptcy on the performance of energy and financial sectors while most of the other sectors suffered significantly. Thus, our results highlight the heterogeneous effect of LBs bankruptcy on different sectors and at different time intervals surrounding the event.

Tip top result goes stale: ACCC-v- Australian Safeway Stores Pty Ltd(No 2)

Bread, its constituents, its methods of manufacture and its price and availability to consumers can claim to be the leitmotiv of competition law, both ancient and modern. The inelasticity of demand for such a staple food explains laws against monopolies being included in the eighteenth century BC Code of Hammurabi, why corn laws exercised the minds of the Gracchi brothers in second century B.C. Rome, and why ineffective regulation of the price of bread was seen as an important precipitator of revolutions in Europe in the eighteenth and nineteenth centuries. In the common law the early restraint of trade case, Mitchell v Reynolds saw a parish wide five year non-competition clause in a contract for the sale of a bakery upheld as reasonable. In the post-Shennan Anti-Trust Act (1890) United States, attempts by manufacturers of macaroni to change its constituents because of the prevailing high price of durm wheat were held in National Macaroni Manufacturers Association v FCT) to constitute price-fixing, an offence illegal per se under American anti-trust law.
