Hybridized teacher education programs in NYC: A missed opportunity?

This qualitative study describes the development of hybrid teacher preparation programs that emerged as a result of a “forced” partnership between university-based and alternative teacher preparation programs in New York City. This hybrid experiment was a short-lived, yet innovative by-product of a somewhat pragmatic arrangement between Teach for America, NYC Teaching Fellows and various universities to meet state requirements for credentialization. The institutions benefited from the arrangement but noteworthy here is the documentation of how the teacher education programs informed each other and potentially created a richer educational experience for teacher candidates than either of the programs had alone. With the development of Relay, a stand-alone, alternate graduate school, the partnership, despite its early promise, was ended. With all of its challenges, this forced partnership was characterized by creative and competitive tensions, rather than what ultimately became two parallel teacher education systems largely isolated and in competition with each other.

The Perceptions of Small Businesses in the Implementation of Cash Management Techniques

The purpose of this paper is to ascertain the perceptions of small business owners on the implementation of cash management techniques in their businesses. This paper also highlights the importance of managing cash inflow and outflow in the business and examines the impact on business profitability and sustainability. The study focused on small businesses in the Tongaat area, South Africa. This research was quantitative, descriptive and cross-sectional in nature. The instrument used to extract the relevant data from respondents was a Likert type questionnaire. The findings of this research identified the perceptions of small business cash management techniques. A short course on cash management could be offered by the Durban University of Technology to small business owners and managers to enhance their basic cash management knowledge in the implementation of cash management techniques

How do public private partnerships influence business school performance in English-speaking Caribbean?

This thesis addresses the question of how business schoolsestablished as public privatepartnerships (PPPs) within a regional university in the English-speaking Caribbean survived for over twenty-one years and achieved legitimacy in their environment. The aim of the study was to examine how public and private sector actors contributed to the evolution of the PPPs. A social network perspective provided a broad relational focus from which to explore the phenomenon and engage disciplinary and middle-rangetheories to develop explanations. Legitimacy theory provided an appropriate performance dimension from which to assess PPP success. An embedded multiple-case research design, with three case sites analysed at three levels including the country and university environment, the PPP as a firm and the subgroup level constituted the methodological framing of the research process. The analysis techniques included four methods but relied primarily on discourse and social network analysis of interview data from 40 respondents across the three sites. A staged analysis of the evolution of the firm provided the ‘time and effects’ antecedents which formed the basis for sense-making to arrive at explanations of the public-private relationship-influenced change. A conceptual model guided the study and explanations from the cross-case analysis were used to refine the process model and develop a dynamic framework and set of theoretical propositions that would underpin explanations of PPP success and legitimacy in matched contexts through analytical generalisation. The study found that PPP success was based on different models of collaboration and partner resource contribution that arose from a confluence of variables including the development of shared purpose, private voluntary control in corporate governance mechanisms and boundary spanning leadership. The study contributes a contextual theory that explains how PPPs work and a research agenda of ‘corporate governance as inspiration’ from a sociological perspective of ‘liquid modernity’. Recommendations for policy and management practice were developed

Assessing Concerns and Leading Pedagogical Innovation in Higher Education: A Case Study of the Arthur Lok Jack Graduate School of Business

Studies of pedagogical innovation indicate that the implementation process is enhanced by addressing teachers’ concerns. Institutions address teacher preparedness mainly from the perspectives of their preparation and institutional support, without recognising teachers’ mental state and particular implementation concerns. This paper adopts the Concerns Based Adoption Model (CBAM) to examine the Stages of Concern (SoC) of faculty involved in the implementation of pedagogical reform. The standardized 35-item SoC questionnaire was sent online to 152 faculty members and 31 responses were obtained. The study found the faculty body had high levels of self-concerns, low levels of impact concerns and a willingness to continue with the implementation process. The study addressed the theoretical gap in teacher preparedness research by combining the SoC with contextual factors

Large‐scale structures and molecular mixing

Scalar mixing and chemical reactions in turbulent shear layers and jets are examined with emphasis on experimental results of high spatial and temporal resolution. Such measurements show that the notion of distinguishing fluids that are molecularly mixed from those that are simply stirred is valid and useful. Two models that seem especially suitable for implementing mixing analyses from this viewpoint are described and speculations on possible connections with the idea of chaotic advection offered

The Effects of Damkohler Number on a Turbulent Shear Layer - Experimental Results

A chemical reaction for which the reaction rate can be varied is studied in a fully developed, two-dimensional, turbulent mixing layer. The layer is formed between two nitrogen streams, one carrying low concentrations of fluorine and the other hydrogen and nitric oxide. For fixed concentrations of fluorine and hydrogen and for nitric oxide concentrations that are small fractions of the fluorine concentration, the heat release is fixed but the overall reaction rate is controlled by the nitric oxide concentration. Therefore, for fixed flow conditions, the nitric oxide concentration determines the ratio of the reaction rate to the mixing rate. For large values of this ratio, the amount of product, at a given downstream location, measured by the mean temperature rise, is independent of the reaction rate, i.e., the reaction is mixing limited. As the reaction rate is reduced the major effects are: (1) amount of product declines (as expected), (2) the mean temperature profile, which is initially some what unsymmetrical because the hydrogen-fluorine freestream concentration ratio is set at a large value, becomes symmetrical, and (3) the ramp-like instantaneous temperature traces within the large structure gradually become more top-hat

Use of passive scalar tagging for the study of coherent structures in the plane mixing layer

Data obtained from the numerical simulation of a 2-D mixing layer were used to study the feasibility of using the instantaneous concentration of a passive scalar for detecting the typical coherent structures in the flow. The study showed that this technique works quite satisfactorily and yields results similar to those that can be obtained by using the instantaneous vorticity for structure detection. Using the coherent events educed by the scalar conditioning technique, the contribution of the coherent events to the total turbulent momentum and scalar transport was estimated. It is found that the contribution from the typical coherent events is of the same order as that of the time-mean value. However, the individual contributions become very large during the pairing of these structures. The increase is particularly spectacular in the case of the Reynolds shear stress

Scalar entrainment in the mixing layer

New definitions of entrainment and mixing based on the passive scalar field in the plane mixing layer are proposed. The definitions distinguish clearly between three fluid states: (1) unmixed fluid, (2) fluid engulfed in the mixing layer, trapped between two scalar contours, and (3) mixed fluid. The difference betwen (2) and (3) is the amount of fluid which has been engulfed during the pairing process, but has not yet mixed. Trends are identified from direct numerical simulations and extensions to high Reynolds number mixing layers are made in terms of the Broadwell-Breidenthal mixing model. In the limit of high Peclet number (Pe = ReSc) it is speculated that engulfed fluid rises in steps associated with pairings, introducing unmixed fluid into the large scale structures, where it is eventually mixed at the Kolmogorov scale. From this viewpoint, pairing is a prerequisite for mixing in the turbulent plane mixing layer
