ABSTRACT In this case, students assume the role of an accounting professional asked by a client to investigate why net income is not as strong as expected. The students must first analyze a set of financial statements to identify areas of possible concern. After determining the areas to investigate, the students use a database query tool to see if they can determine causes by examining transaction level data. Finally, the students are asked to professionally communicate their findings and recommendations to their client. The case provides students with experience in using query-based approaches to answering business questions. It is appropriate for students with basic query and financial analysis skills and knowledge of internal controls. A Microsoft Access database with transaction details for the final seven months of the current year as well as financial statements for the current and prior year are provided.

HMG-CoA reductase (HMGR) undergoes feedback-regulated degradation as part of sterol pathway control. Degradation of the yeast HMGR isozyme Hmg2 is controlled by the sterol pathway intermediate GGPP, which causes misfolding of Hmg2, leading to degradation by the HRD pathway; we call this process mallostery. We evaluated the role of the Hmg2 sterol sensing domain (SSD) in mallostery, as well as the involvement of the highly conserved INSIG proteins. We show that the Hmg2 SSD is critical for regulated degradation of Hmg2 and required for mallosteric misfolding of GGPP as studied by in vitro limited proteolysis. The Hmg2 SSD functions independently of conserved yeast INSIG proteins, but its function was modulated by INSIG, thus imposing a second layer of control on Hmg2 regulation. Mutant analyses indicated that SSD-mediated mallostery occurred prior to and independent of HRD-dependent ubiquitination. GGPP-dependent misfolding was still extant but occurred at a much slower rate in the absence of a functional SSD, indicating that the SSD facilitates a physiologically useful rate of GGPP response, and implying that the SSD is not a binding site for GGPP. Non-functional SSD mutants allowed us to test the importance of Hmg2 quaternary structure in mallostery:  a non-responsive Hmg2 SSD mutant strongly suppressed regulation of a co-expressed, normal Hmg2. Finally, we have found that GGPP-regulated misfolding occurred in detergent-solubilized Hmg2, a feature that will allow next-level analysis of the mechanism of this novel tactic of ligand-regulated misfolding.

AbstractEntrepreneurial ecosystems provide a rich context for analyzing entrepreneurial outcomes such as new venture growth. In most entrepreneurship research, influence of context or environment is undermined or controlled. Also, most studies consider either macro- or micro-level factors using single-level analysis, which mute the higher-level influences on new firm growth. To overcome these gaps, we empirically consider macro- and micro-level factors together, and their cross-level interactions to portray the nexus of entrepreneurs and entrepreneurial ecosystem in growth of new independent ventures in the various US metros. Our findings provide interesting insights on the moderating effects of prior experiences of founders on ecosystem attributes and firm growth.

Abstract This article discusses the mediating role of service providers between citizens and refugee reception policies. Based on an analysis of interviews with local government officials and NGO workers and observations in two districts of Istanbul, I examine the ‘street-level justifications’ that service providers use to counter anti-refugee resentments expressed by the citizens. The article suggests that as street-level bureaucrats endeavour to justify their work with refugees through three types discursive strategies; cultural similarity, call for empathy, and pragmatic explanations. Such strategies by constantly re-defining us and them, bear implications for social cohesion. The article offers a meso-level analysis of refugee reception policies in the Turkish context and highlights the limits of initial hospitality. The findings have wider implications for other contexts where the settlement of displaced or migrant populations is rather nascent, policies are top-down and where bureaucratic structures mediate among displaced populations, citizens, and the resources available to them.
