Power to Do…What? Department Heads’ Decision Autonomy and Strategic Priorities

Using questionnaire data from the 2010 Survey of Academic Chairs, the study focuses on decision autonomy, a component of the power wielded by science, technology, engineering and mathematics (STEM) department chairs in U.S. research extensive universities. A “power index” is developed to measure chairs’ decision autonomy, specifically their control of resources employed in negotiations with faculty job candidates. The study asks: What determines the degree of decision autonomy power possessed by department heads; and, what are the strategic implications of department heads’ degree of this particular aspect of power? Results of an ordered logistic regression model show that having more power is associated with being hired from outside the current university, being male, and with department size. The power index is employed to predict departmental strategic priorities. Results show that the power index is positively associated with a strategic priority for research. The results show a negative relationship between degree of chair decision autonomy and a priority to increase faculty lines. A student-focused strategy is not predicted by the power index but is related to the size, with larger departments placing less emphasis on numbers or quality of students.     

Notes on contributors

This article examines how teacher thinking is socially negotiated yet individually enacted. Through a case study approach, the author explores how the identities of a first-year kindergarten teacher were fashioned linguistically as she moved through the contexts of her teacher education program, the elementary school in which she taught and the personal aspects of her life. Using ethnographic techniques, multiple layers of data were gathered in nested contexts. A theoretical framework was developed by juxtaposing the work of the Russian theorists Valentin Volosinov on the concept of ideologies and M.M. Bakhtin on his notions of language to guide the analysis of data. Findings indicate that by providing prospective teachers with the tools for conceptualizing teacher thinking as social, teacher educators can provide future educators with alternative ways to author their identities and help them to understand that they can create possibilities for all children.     

Launch vehicle attitude control using sliding mode control and observation techniques

In determining flight controls for launch vehicle systems, several uncertain factors must be taken into account, including a variety of payloads, a wide range of flight conditions and different mission profiles, wind disturbances and plant uncertainties. Crewed vehicles must adhere to human rating requirements, which limit the angular rates. Sliding mode control algorithms that are inherently robust to external disturbances and plant uncertainties are very good candidates for improving the robustness and accuracy of the flight control systems. Recently emerging Higher Order Sliding Mode (HOSM) control is even more powerful than the classical Sliding Mode Controls (SMC), including the capability to handle systems with arbitrary relative degree. This paper proposes sliding mode launch vehicle flight controls using classical SMC driven by the sliding mode disturbance observer (SMDO) and higher-order multiple and single loop designs. A case study on the SLV-X Launch Vehicle studied under a joint DARPA/Air Force program called the Force Application and Launch from CONtinental United States (FALCON) program is shown. The intensive simulations demonstrate efficacy of the proposed HOSM and SMC-SMDO control algorithms for launch vehicle attitude control.     

The development of nonverbal working memory and executive control processes in adolescents

The prefrontal cortex modulates executive control processes and structurally matures throughout adolescence. Consistent with these events, prefrontal functions that demand high levels of executive control may mature later than those that require working memory but decreased control. To test this hypothesis, adolescents (9 to 20 years old) completed nonverbal working memory tasks with varying levels of executive demands. Findings suggest that recall-guided action for single units of spatial information develops until 11 to 12 years. The ability to maintain and manipulate multiple spatial units develops until 13 to 15 years. Strategic self-organization develops until ages 16 to 17 years. Recognition memory did not appear to develop over this age range. Implications for prefrontal cortex organization by level of processing are discussed.     

Achieving scale of farmer reach with improved common bean technologies: the role of village-based advisors

Purpose: We assessed the effectiveness of Village-based Advisors (VBAs) as a novel approach for scaling up improved common bean technologies in southern highlands of Tanzania.

Design/methodology/approach: Data were gathered through focus group discussions (FGDs) and interviews with 11 VBAs and 102 farmers (37% female). The effectiveness of VBAs was assessed based on farmer reach, farmer knowledge, and application of new technologies.

Findings: VBAs played important roles in reaching a wide audience of farmers, with common bean technologies. There was evidence of uptake of promoted common bean practices by farmers, enhanced by judicious incentives such as higher yields, increased land productivity, and labor-saving. VBAs shared information mainly through farm visits and community meetings. Extension materials facilitated VBA engagement of farmers even in informal settings, enhancing information flow beyond village boundaries. The current success of the VBA approach stems from the fact that VBAs are motivated by the rewards they receive – both cash and non-cash.

Practical implications: VBAs are relevant in scaling up improved common bean technologies in rural Tanzania and similar settings, because of farmer understanding and trust. For sustainability, there is need to develop a more systematic incentive structure for VBAs through business development, and knowledge enhancement to keep pace with innovations to address emerging production challenges.

Theoretical implications: Access to extension service providers who are knowledgeable of farmers’ context enhances learning and uptake of innovations.

Originality/value: Results fill information gap on the effectiveness of VBAs as knowledge and input disseminators, achieving scale of farmer reach with agricultural innovations.     

Comparing cognitive performance in illiterate and literate children

While it is known that the process of becoming literate begins in early childhood and usually involves several years of schooling, research related to cognitive characteristics has been done mostly on illiterate adults, and information concerning illiterate children is therefore limited. The aim of the present study, involving 21 illiterate and 22 literate Mexican children aged 6 to 13, was to investigate the effects of literacy on neuropsychological characteristics during childhood. The children??s performance on 16 cognitive domains of the Evaluación Neuropsicológica Infantil (ENI, Child Neuropsychological Assessment) was examined in three mixed within- and between-groups profile analyses. The results suggest that the effect of literacy observed in adults is already evident in children in almost every task analysed. Moreover, the fact that an age effect was detected for the calculation abilities suggests that maths learning is school- and environment-dependent.     

The commingling of teacher researcher identities: a mediated approach to teaching action research

This article chronicles and discusses a two-semester graduate level action research course in which the co-authors were instructors. Evidence of prospective teachers' appropriation of a ‘teacher researcher’ identity prompted a closer look at the dynamics of the course experience. Using a theoretical foundation based on the work of Vygotsky, Wertsch, Kozulin and Bakhtin, the notions of experiential learning, shared pedagogical mediation, collaborative problem posing and problem solving, and a resultant commingling of teacher and researcher identities are explored     

A New Politics of the Principalship? Accountability-Driven Change in New York City

How do principals adjust to new standards and measurement rulers of school performance when they are coupled with high-stakes consequences? Adopting a contingent view of leadership and a multiple accountabilities framework, this qualitative study explores how high school principals enacted their accountability in New York City, by comparing two periods: just before such policy changes took effect and just after. We observed large differences in principals' attention to external political, bureaucratic, and market accountabilities; how much accountability conflict or alignment was experienced; and how principals' sense of professionalism was constructed. These differences may portend a new politics of the principalship.     

Strengthening Community Schools Through University Partnerships

Given the mounting call for academic achievement gains in America's public schools—particularly urban schools labeled “failing”—the need for community engagement to tackle a host of underlying social challenges warrants the resources of the nation's colleges and universities (Harkavy & Hartley, 2009). Because colleges and universities are often underutilized anchors of resources in communities, coordinated alignment of K-12 and higher education goals can create a seamless pipeline of educational attainment for communities challenged to produce high academic achievement. Higher education's engagement with community schools further helps to address the whole child and their families in K-12 education by expanding the opportunities for the students and community to access necessary support services. Drawing upon experiences of Indiana University Purdue University Indianapolis (IUPUI) and collaboration with its adjacent neighborhoods, this article illustrates the transformative and relevant impact of university and community engagement, as well as new pedagogical approaches to teaching, learning, and training. This article reflects upon the experiences of IUPUI and nearby George Washington Community High School as it can uniquely serve as a roadmap for other school community/university partnerships that are interested in embarking upon a similar education reform path.     

A review and new framework for instructional design practice variation research

This article reviews practice variation in the field of instructional design. First, it compares instructional designer practice as reported or observed in several classic research studies. This analysis is framed by the standards established by the International Board for Training, Performance, and Instruction competencies for planning and analysis, design and development, implementation, and management. Although no certain causal linkages exist, we briefly review some of the reasons posited in the literature to explain instructional design practice variation (lack of time and resources, control in decision making, the designer's perception of a task, underlying philosophical beliefs, and designer expertise). Limitations of the literature base are explored, followed by a proposal for an alternative view of instructional design practice variation and recommendations.
