In the last twenty years, a significant amount of work has been done in the theoretical understanding of grain boundaries. The various proposed grain boundary models suggest the existence of coincidence site lattice (CSL) boundaries at specific misorientations where a periodic structure representing a local minimum of energy exists between the two crystals. In general, the boundary energy depends not only upon the density of CSL sites but also upon the boundary plane, so that different facets of the same boundary have different energy. Here we describe TEM observations of the dissociation of a Σ=27 boundary in silicon in order to reduce its surface energy and attain a low energy configuration.The boundary was identified as near CSL Σ=27 {255} having a misorientation of (38.7±0.2)°/[011] by standard Kikuchi pattern, electron diffraction and trace analysis techniques. Although the boundary appeared planar, in the TEM it was found to be dissociated in some regions into a Σ=3 {111} and a Σ=9 {122} boundary, as shown in Fig. 1.

Starting with a personal perspective this piece outlines the place and role of the arts in the criminal justice system in the UK. It paints an optimistic picture, though an unsettling one, because the imagination and reflexiveness of the arts reveals a great deal about the causes of crime and the consequences of incarceration. It raises questions about the transforming impact of the arts: how the benefits could, and should, be optimised and why evaluations of arts interventions are consistent in identifying the need for a non-coercive, more socially focused, paradigm for rehabilitation. It concludes that the deeper the arts are embedded in the criminal justice system the greater the benefits will be, that a more interdisciplinary approach would support better theoretical understanding, and that increased capacity to deliver arts in the criminal justice system is needed to offer more people a creative pathway out of crime.

The article is devoted to the actual issue – institutional analysis of initiative budgeting and territorial public selfgovernment, as well as the possibility of their integration. Over the past few years, a system of civil participation in budget decisions has been built in Russia, the regulatory framework of practices has been created, thousands of employees of state and local government bodies have been trained, project centers have appeared for ensuring development of initiative budgeting. Citizen participation in budget decisions can significantly accelerate the development of the lower level of local government. Initiative budgeting is an innovative instrument of public finance and at the same time a social technology allowing for the real involvement of citizens in the issues of state and municipal governance. Initiative budgeting development programs make it possible to transfer financing of projects aimed at solving local issues with the participation of citizens onto a systemic basis. The results and materials of this study can serve a foundation for theoretical understanding of the institutional development of public finances at the regional and local levels. At the same time, this practical area that was intensively developing in recent years requires deep institutional analysis.

How can we best empower people living in the most economically disadvantaged areas of the world to improve their lives in ways that matter to them? This book investigates work of the NGO Tostan as a working model of human development. The study is grounded in the ethnographic study of the actual change that happened in one West African village. The result is a powerful mix of theory and practice that questions existing approaches to development and that speaks to both development scholars and practitioners. Divided into three parts, the book firstly assesses why top-down approaches to education and development are unhelpful and offers a theoretical understanding of what constitutes helpful development. Part two examines Tostan's community-based participatory approach as an example of a helpful development intervention, and offers qualitative evidence of its effectiveness. Part three builds a model of how community-led development works, why it is helpful, and what practitioners can do to help people at the grassroots level lead their own human development.

Timber-concrete composite beams are a new type of structural element that is environmentally friendly. The structural efficiency of this kind of beam highly depends on the stiffness of the interlayer connection. The structural efficiency of the composite was evaluated by experimental and theoretical investigations performed on the relative horizontal slip and vertical uplift along the interlayer between composite’s timber and concrete slab. Differential equations were established based on a theoretical analysis of combination effects of interlayer slip and vertical uplift, by using deformation theory of elastics. Subsequently, the differential equations were solved and the magnitude of uplift force at the interlayer was obtained. It was concluded that the theoretical calculations were in good agreement with the results of experimentation.

Islamic Communication and Broadcasting or commonly known as KPI, as one of the majors in Islamic colleges, must have an identity. Basically, the KPI’s scientific design can not be separated from two things, first, at the scientific level, the device is able to make science communication and science propaganda as the basis of activity design and the movement of Islamic broadcasting through various paradigmatic, theoretical, and methodological approaches. This is what is referred to as the ability of theoretical understanding (knowledge-based capability). Second, at a practical level, facilitating the growth of capabilities that could be the foundation undergraduate professional competence of KPI. Komunikasi dan penyiaran Islam atau yang biasa dikenal dengan KPI, sebagai salah satu jurusan di perguruan tinggi agama Islam, harus mempunyai identitas. Pada dasarnya desain keilmuan KPI tidak terlepas dari dua hal, Pertama, di level keilmuan, mampu menjadikan perangkat ilmu komunikasi dan ilmu dakwah sebagai basis dari desain aktivitas dan gerakan penyiaran Islam melalui berbagai pendekatan paradigmatik, teoritik, dan metodologis. Inilah yang disebut sebagai kemampuan pemahaman teoretik (knowladgebased capability). Kedua, di level praktis, memfasilitasi tumbuh kembangnya kemampuan yang dapat menjadi pijakan kompetensi profesi sarjana KPI.
