Entrepreneurial and Business Growth and the Quest for a “Comprehensive Theory”: Tilting at Windmills?

Even though there has been sustained interest in growth for almost 50 years, relatively little is known about this phenomenon and much confusion and misunderstanding surrounds it. Based on a literature review and the articles in this special issue we make three recommendations that we believe will allow theory to advance and be applicable in practice. First, that discourse between key stakeholders is encouraged in order to achieve greater understanding. Second, that focus is placed on " growth as a process," rather than as a " change in amount." Third, that knowledge production requires inclusivity and pluralism in research perspectives and approaches. © 2010 Baylor University.

Laïcité is what Laïcité does: Rethinking the French cult controversy

France’s distinctive reaction towards “cults” is generally described as a result of laïcité’s consubstantial problems with religious diversity. The aim of this article is to present an alternative way of thinking about the French cult controversy and, ultimately, about the concept of “laïcité” as an explanatory framework for France’s response to religious diversity. It draws on empirical data to look at how notions such as “laïcité” and “cults” are used in official discourses and translated into administrative practice. This approach will underline that laïcité is not a driving force that predetermines a unilateral response to “cults”, but that laïcité is as laïcité does, in other words a highly claimed and contested value, reflecting divergent political and administrative approaches of the cult phenomenon. The framework “laïcité versus religious diversity” is also undermined by another crucial observation. While it sees the cult controversy as primarily a religious issue, it seems that the recent revitalisation of the combat against “cults” was made possible by its partial dissociation from the religious sphere and its extension to a wide range of practices and new areas.

Global down-regulation of HOX gene expression in PML-RAR alpha(+) acute promyelocytic leukemia identified by small-array real-time PCR

Acute promyelocytic leukemia (APL) is associated with a reciprocal and balanced translocation involving the retinoic acid receptor-alpha (RARalpha). All-trans retinoic acid (ATRA) is used to treat APL and is a potent morphogen that regulates HOX gene expression in embryogenesis and organogenesis. HOX genes are also involved in hematopoiesis and leukemogenesis. Thirty-nine mammalian HOX genes have been identified and classified into 13 paralogous groups clustered on 4 chromosomes. They encode a complex net-Work of transcription regulatory proteins whose precise targets remain poorly understood. The overall function of the network appears to be dictated by gene dosage. To investigate the mechanisms involved in HOX gene regulation in hematopoiesis and leukemogenesis by precise measurement of individual HOX genes, a small-array real-time HOX (SMART-HOX) quantitative polymerase chain reaction (PCR) platform was designed and validated. Application of SMART-HOX to 16 APL bone marrow samples revealed a global down-regulation of 26 HOX genes compared with normal controls. HOX gene expression was also altered during differentiation induced by ATRA in the PML-RARalpha(+) NB4 cell line. PML-RARalpha, fusion proteins have been reported to act as part of a repressor complex during myelold cell differentiation, and a model linking HOX gene expression to this PML-RARalpha repressor complex is now proposed.
