In Part I of this paper we presented a formal procedure for determining the various state structures associated with any given digital network with the dimension of state vector equal to the number of dynamic elements in the network. For noncanonic networks, it is sometimes possible to find state structures with state vectors of reduced and even lowest dimension. Such a state structure is defined to be reduced state structure except for the case where state vector dimension is the lowest possible (the associated state structure is termed minimal). A graph-theoretic procedure for determing the existence of conditions under which a state structure can be simplified is outlined in this part of the paper. 相似文献

Leadership development (LD) activity and its effectiveness has not been explored rigorously across changing university settings globally. As Higher Education settings change radically throughout the world, Higher Education professionals are operating in more uncertain environments, and leaders are taking increasingly complex and diverse approaches to their leadership roles. LD activities therefore become important in supporting this highly complex context, yet little is known in the literature about LD and its impact in Higher Education. We examine peer‐reviewed work on LD in Higher Education settings globally to understand what may be learned about its content, processes, outcomes and impact. Our results suggest the current literature is small‐scale, fragmented and often theoretically weak, with many different and coexisting models, approaches and methods, and little consensus on what may be suitable and effective in the Higher Education context. We reflect on this state of play and develop a novel theoretical approach for designing LD activity in Higher Education institutions. 相似文献

While research has documented the many ways in which student voice can enable educational change, the process of how adults can help to enable student voice is less clear. This article examines how adults new to working as advisors of student voice initiatives begin to develop partnerships with young people. Using a Youth-Adult Partnership continuum as a framework, three cases represent a range of beliefs of student leadership. Using the archetypes of Captain, Dreamer, and Architect, the cases indicate how the adults began their work with youth with adult-centered, a student-centered, and an equilibrium approach, respectively. While the article highlights that adults must learn how to scaffold youth participation to help them to develop the leadership skills necessary to share in the work of the partnership, little training and materials exist for adults to learn how to scaffold learning. Part of this training includes the willingness for adults to recognize that they themselves need to change as well in order to facilitate youth leadership. 相似文献

The need for the integration of information literacy (IL) into the world of social enterprise (organizations that apply market-based strategies to achieve a social purpose) is critical for like organizations providing workforce development services to disabled populations. The skill set associated with IL is vital to the success of this population to achieve economic self sufficiency. Disability Program Navigators trained in information sciences and placed into community-based One Stop Career Centers can serve as the gatekeepers for, and trainers on, the multiple resources available to support this goal. This article examines an exciting new program model that charts the course for expanding collaborative IL and social enterprise pilots nationwide. 相似文献

Ectodermal dysplasia (ED) is a genetic disorder affecting the skin, hair, nails, teeth and sweat glands. The clinical presentation is heterogenous; however, hypohidrotic (reduced sweat) ectodermal dysplasia (HED) being the commonest. Also known as anhidrotic ED, sweat glands are sparse or rudimentary, leading to dysregulation of body temperature and episodes of uncontrolled hyperthermia due to reduced sweating. Of the many aids to document hypohidrosis in HED, we present here the technique of pilocarpine iontophoresis to induce, collect and measure sweat. Evaluation of sweat generated (against normally obtained values) is a non-invasive alternative to establish hypohidrosis in disorders such as HED. This augments clinical decision levels to plan skin biopsy for confirmation of diagnosis and facilitates patient management and early discharge. We present two cases of HED that were primarily diagnosed with sweat gland dysplasia using pilocarpine iontophoresis, and later confirmed with skin biopsy findings. 相似文献

An elementary derivation of the Lamb Shift, as originally given by Hans Bethe, is attempted, with a short historical background
on the evolution of QED since the beginning of the last century. The treatment is for a non-relativistic electron, in keeping
with Bethe’s proverbial insight into the problem, which renders irrelevant the effect of the electron spin on the problem.
The Kramer idea of renormalization is implemented through a simple subtraction of the self-energy of a free electron from
that of the electron bound in a hydrogen atom.

The literature demonstrates that stress in the working life of academics has increased over recent years. However, qualitative research on how academics cope with this is very scarce. Using online interviewing with thematic analysis, this paper examines how 31 academics in a post-92 predominantly teaching-focused UK university cope with the stressors of work. An innovation was to ask about both positive and negative experiences at work unlike most stress research which focuses only on negatives. Six themes emerged from the data; administrative loads, coping with stress at work, task preferences, the academic role, and positive and negative feelings around research/scholarship and thoughts around leaving academia. Increases in student numbers, being able to spend less time with students, heavy workloads, increasing administration, poor management, funding cuts and government initiatives threatening the future of education, obtaining research funding, and increasing insecurity of academic posts were all stressors. Positives identified included satisfaction gained from teaching students, support from colleagues, relative autonomy at work and the ability to manage their time more effectively were perceived as factors that can moderate some of the negative consequences of work stress. Overall, academics reported being happy at work because of the satisfaction gained from teaching and research. 相似文献

A novel principle known as block transformation is developed for the block implementation of two-dimensional (2-D) digital filters. It employs the one-dimensional (1-D) block implementation concept forwarded by Burrus (7) as a basic tool. Using this block transformation principle three distinct forms of 2-D block equations are derived. The generalized nature of the approach presented here facilitates the straightforward extension of this technique to higher dimensional digital filters. 相似文献
