Effect Of Surface

The first part of the paper discusses two problems in which the role of residual stresses may be treated using the procedures of fracture mechanics. One is the significant degradation of the tensile strength of glass due to the residual stresses produced by surface damage. The other is the effect of surface compressive stresses in inhibiting the detection of surface flaws. The second part of the paper discusses the inverse problem of using fracture mechanics solutions to measure residual stresses. This approach which has only been developed in the past decade leads to an experimental procedure which is easy to implement and is also more versatile than conventional methods.

The Relationship

The role of infrastructure in encouraging transportation cycling in smaller cities with a low prevalence of cycling remains unclear. To investigate the relationship between the presence of infrastructure and transportation cycling in a small city (Lethbridge, AB, Canada), we interviewed 246 adults along a recently-constructed bicycle boulevard and two comparison streets with no recent changes in cycling infrastructure. One comparison street had a separate multi-use path and the other had no cycling infrastructure. Questions addressed time spent cycling in the past week and 2 years prior and potential socio-demographic and psychosocial correlates of cycling, including safety concerns. Finally, we asked participants what could be done to make cycling safer and more attractive. We examined predictors of cycling using gender-stratified generalized linear models. Women interviewed along the street with a separate path reported cycling more than women on the other streets. A more favorable attitude towards cycling and greater habit strength were associated with more cycling in both men and women. Qualitative data revealed generally positive views about the bicycle boulevard, a need for education about sharing the road and for better cycling infrastructure in general. Our results suggest that, even in smaller cities, cycling infrastructure may encourage cycling, especially among women.

Important Basis

Over the past few decades, two-factor models of social cognition have emerged as the dominant framework for understanding impression formation. Despite the differences in the labels, there is wide agreement that one dimension reflects sociability potential, and the other, competence. One way in which the various two-factor models do clearly differ, however, is in the way the dimensions incorporate or produce evaluations of morality. Aristotle saw morality as the most important basis on which to form positive evaluations, because competence and sociability could only be virtuous, sincere, and trustworthy if expressed through a moral character. This chapter highlights research demonstrating the unique and possibly primary role of morality in social cognition. We clarify the dynamic, interactive, and conjoint effects of morality on social perception, and argue morality, competence, and sociability are three influential and interactive dimensions of social perception.

The transition from the Mesolithic to the Neolithic in Britain and Ireland remains one of the most debated and contested transitions of prehistory. Much more complex than a simple transition from hunting and gathering to farming, the Mesolithic–Neolithic transition in Britain has been discussed not only as an economic and technological transformation, but also as an ideological one. In western Britain in particular, with its wealth of Neolithic monuments, considerable emphasis has been placed on the role of monumentality in the transition process. Over the past decade the author‧s research has concentrated on the early Neolithic monumental traditions of western Britain, a deliberate focus on areas outside the more ‘luminous’ centres of Wessex, the Cotswold–Severn region, and Orkney. This chapter discusses the transition in western Britain, with an emphasis on the monuments of this region. In particular, it discusses the areas around the Irish Sea – west Wales, the Isle of Man, south-west and western Scotland – as well as referring to the sequence on the other side of the Irish Sea, specifically eastern Ireland.

Given the massive changes that Brazil has undergone in the past century, particularly in distancing itself linguistically from its former colonizer, this study is an attempt to determine the role of translation in the country's cultural evolution. Translational approaches have developed along opposing poles: on the one hand, a strong resistance to incorporating orally-driven alterations in the written language, while on the other, a slow, halting movement toward convergence of the two, and both approaches are charged with political and ideological intentionality. Publishing houses, editors and translators are gatekeepers and agents whose activities provide a glimpse into the mechanism of national linguistic identity, either contributing to or resisting the myth of a homogenized Portuguese language.

AbstractPrison leave was introduced into the Finnish legal system in 1971, with the aim to reduce negative effects of institutionalization and disadvantages caused by the length of the prison sentence. After the total reform of prison legislation in 2006, the role of the prison leave has become even more central; the number of prisoners has decreased, but the amount of prison leave has increased. Historically, the length of the sentence has been the most common ground for prison leave. A prisoner can be granted a prison leave when two thirds of the prison term has been served, for example, after 2 years if the length of the total sentence served in prison is 3 years. However, during the past 10 years, prison leave based on an important reason has grown into the most common type of prison leave. This indicates a structural change from the rigid legal rules to a more flexible practice. In 2018, there were about 17,000 prison leave applications, and over 13,000 of those were granted, i.e. 79%. The conditions were breached 466 times, which is 3.5% of all prison leaves. The most common breaches of prison leave conditions were returning from a prison leave after the set time limit or under the influence of alcohol or drugs. The majority of prison leave applications are decided in the prisons. On the other hand, for example, the decision on the prison leave of a life-sentenced prisoner is made by the Criminal Sanctions Agency. There have been significant differences in the probability of granting prison leave, which are emphasized especially in the practices of closed prisons. Among those prisoners who serve longer than 1 year in prison, the application rate of prison leave rises over 90%. For the sentences under 3 months, it is less than 20%.

This article discusses a recent art project created by the Wiradjuri and Kamilaroi artist Jonathon Jones, which was commissioned to commemorate the opening of the revitalized Hyde Park Barracks in Sydney in early 2020. Jones’ work involves a dramatic installation of red and white crushed stones laid throughout the grounds of the barracks, merging the image of the emu footprint with that of the English broad convict arrow to ‘consider Australia’s layered history and contemporary cultural relations’. This work was accompanied by a ‘specially-curated programme’ of performances, workshops, storytelling and Artist Talks. Together, these elements were designed to unpack how certain ‘stories determine the ways we came together as a nation’. As one of the speakers of the Artist Talk’s programme, I had a unique opportunity to experiment with what colleagues and I have been calling ‘Creative histories’ in reference to the way some artists and historians are choosing to communicate their research about the past in ways that experiment with form and function and push disciplinary or generic boundaries. This article reflects upon how these two distinct creative history projects – one visual art, the other performative – renegotiate the complex and contested pasts of the Hyde Park Barracks. I suggest that both examples speak to the role of memory and creativity in shaping cultural responses to Australia’s colonial past, while Jones' programme illustrates how Indigenous artists and academics are making a profound intervention into contemporary understandings of how history is ‘done’ in Australia.

In the context of government, what do we mean by the phrase “a learned man”?* I take it we can mean a variety of things. On the one hand, we can have in mind the specialist, the expert, the man with an intensive and specialized background in a particular field of knowledge. On the other hand, we can have in mind the man with general wisdom, with that feeling for the past and the future which enriches a sense for the present, and with that appreciation for wider loyalties which deepens patriotism to one's country and finds bonds between it and Western culture and links with the universal aspirations of mankind.

The past few decades have been marked by an increasing discussion on the role of dialogue in anthropology, especially following the anthropological turn of the 80s, when the discipline was looked upon as one “writing a culture” rather than understanding it from the insider’s perspective, while the ethnographer was thought of as the epistemic dictator, incapable of establishing a dialogical relation with his subjects of inquiry. The power relationship was indeed one of the most prominent problems in creating an equal, dialogical setting between the anthropologist and the other culture. This paper aims at revisiting feminist anthropology tracing the elements which constituted it, its original inspiration, and main motifs of action mostly gathered around the strong male bias of the discipline. This bias was predominantly manifested in the monological, androcentric understanding and exploration of cultures. In tracing these aspects, and acknowledging the more egalitarian status of this discipline since its early days versus other social sciences (Margaret Mead, Ruth Benedict were among the most prominent women anthropologists), the paper will look at early women anthropologists works some of which were excluded from the canon. It will also point to the existence of strong male bias in ethnography and the discipline as a whole, thus triggering the emergence of feminist anthropology with its capacity for reflexivity and accountability in ethnographic work.

Abstrak. Peran magis religius Bengawan Solo adalah penting bagi pendirian Kota Surakarta. Peran ini berkaitan dengan kekuatan gaib, roh halus, dan atau roh-roh nenek moyang yang ada pada sungai khususnya di daerah pertemuan dua sungai. Kepercayaan terhadap kekuatan gaib merupakan hal mendasar dalam kehidupan orang Jawa, akan tetapi hal tersebut kurang mendapat perhatian dari para ahli sejarah maupun arkeologi. Tujuan dari penelitian ini adalah untuk memperluas wawasan mengenai kepercayaan orang Jawa terhadap kekuatan gaib dan roh halus yang ada pada tempat tinggal mereka. Survei, fenomenologi, dan kajian pustaka adalah metode yang digunakan untuk mengungkap lebih dalam peran magis religius dari sungai tersebut. Hasil dari penelitian ini adalah peran magis religius Bengawan Solo terhadap Kota Surakarta, yaitu daerah sekitar pertemuan dua sungai karena dianggap sakral dan kepercayaan terhadap konsep kosmologi Jawa, bahwa sungai merupakan bagian penting dalam pembentukan tata ruang kota. Penelitian ini sekaligus membuktikan adanya kontinuitas budaya yang hidup di masyarakat sekitar Bengawan Solo sejak dahulu hingga kini.Abstract. The magical-religious role of Bengawan Solo (Solo River) in the establishment of Surakarta was crucial. It was related to mystical power, ghosts, or spirits of ancestors, especially those that reside at a confluence of two rivers. Belief in mystical power was the foundation of Javanese life, but not enough attention has been paid by historians as well as archaeologists. The aim of this research is to widen people’s insight about the belief of the Javanese people to the supernatural power and spirits that inhabited their dwelling places. Survey, phenomenology, and bibliographical study are the methods used to reveal more about the magical-religious role of the river. Results of the research are an understanding of the magical-religious role of Bengawan Solo in the establishment of Surakarta city as shown in the location of the city, which is close to the confluence of two rivers because such location is conceived as sacred, and the other is a belief to the Javanese cosmological concept that rivers are important to the establishment of city layout. It also proves that there is a continuity among the Javanese people who live around the Bengawan Solo from the past until nowadays.

RE-1 silencing transcription factor (REST) (known also as NRSF) is a well-known transcription repressor whose strong decrease induces the distinction of neurons with respect to the other cells. Such distinction depends on the marked increased/decreased expression of specific genes, accompanied by parallel changes of the corresponding proteins. Many properties of REST had been identified in the past. Here we report those identified during the last 5 years. Among physiological discoveries are hundreds of genes governed directly/indirectly by REST, the mechanisms of its neuron/fibroblast conversions, and the cooperations with numerous distinct factors induced at the epigenetic level and essential for REST specific functions. New effects induced in neurons during brain diseases depend on the localization of REST, in the nucleus, where functions and toxicity occur, and in the cytoplasm. The effects of REST, including cell aggression or protection, are variable in neurodegenerative diseases in view of the distinct mechanisms of their pathology. Moreover, cooperations are among the mechanisms that govern the severity of brain cancers, glioblastomas, and medulloblastomas. Interestingly, the role in cancers is relevant also for therapeutic perspectives affecting the REST cooperations. In conclusion, part of the new REST knowledge in physiology and pathology appears promising for future developments in research and brain diseases.
