The problem of "understandinq" electron microscope imaqes becomes more acute as the resolution is improved. The naive interpretation of an imaqe as representinq the projection of an atom density becomes less and less appropriate. We are increasinqly forced to face the complexities of coherent imaqinq of what are essentially phase objects. Most electron microscopists are now aware that, for very thin weakly scatterinq objects such as thin unstained bioloqical specimens, hiqh resolution imaqes are best obtained near the optimum defocus, as prescribed by Scherzer, where the phase contrast imaqe qives a qood representation of the projected potential, apart from a lack of information on the lower spatial frequencies. But phase contrast imaqinq is never simple except in idealized limitinq cases.

An understanding of the specific interactions of actin with regulatory proteins has been limited by the lack of information about the structure of the actin filament. Molecular actin has been studied in actin-DNase I complexes by single crystal X-ray analysis, to a resolution of about 0.6nm, and in the electron microscope where two dimensional actin sheets have been reconstructed to a maximum resolution of 1.5nm. While these studies have shown something of the structure of individual actin molecules, essential information about the orientation of actin in the filament is still unavailable.The work of Egelman & DeRosier has, however, suggested a method which could be used to provide an initial quantitative estimate of the orientation of actin within the filament. This method involves the quantitative comparison of computed diffraction data from single actin filaments with diffraction data derived from synthetic filaments constructed using the molecular model of actin as a building block. Their preliminary work was conducted using a model consisting of two juxtaposed spheres of equal size.

Amphibians have paired muscular pump organs, called “lymph heart”, which rhythmically pump back the lymph from the large subcutaneous lymph sacs into the veins. The structure and ultrastructure of these organs is well known but to date there is a lack of information about the innervation of lymph hearts. Therefore has been carried out an ultrastructural study in order to study the distribution of the nerve fibers, and the morphology of the neuromuscular junctions in the lymph heart wall.

Abstract. Background: Early identification and appropriate referral services are priorities to prevent suicide. Aims: The aim of this study was to describe patterns of identification and referrals among three behavioral health centers and determine whether youth demographic factors and type of training received by providers were associated with identification and referral patterns. Method: The Early Identification Referral Forms were used to gather the data of interest among 820 youth aged 10–24 years who were screened for suicide risk (females = 53.8%). Descriptive statistics and binary logistic regressions were conducted to examine significant associations. Results: Significant associations between gender, race, and age and screening positive for suicide were found. Age and race were significantly associated with different patterns of referrals and/or services received by youths. For providers, being trained in Counseling on Access to Lethal Means was positively associated with number of referrals to inpatient services. Limitations: The correlational nature of the study and lack of information about suicide risk and comorbidity of psychiatric symptoms limit the implications of the findings. Conclusion: The results highlight the importance of considering demographic factors when identifying and referring youth at risk to ensure standard yet culturally appropriate procedures to prevent suicide.

Human beings have always left signs of their activities behind them. These signs take both tangible and intangible forms, including buildings, sites, sculptural works, antiquities, rock art paintings, belief systems, and traditions. The people of this millennium have recognized the remains of our fore-bears namely archaeological, architectural monuments, sites, and cultural works as an integral part of the cultural heritage of all humanity. They also recognized the fact that heritage is an invaluable source of information about the lives and activities of human beings and their artistic and technical capabilities over the centuries. The Nigerian Ancient Art Tradition which spans eight thousand years is a product of diverse artists from Dufuna, Nok, Igbo-Ukwu, Ife, Owo, Benin, Tada, etc. Also remarkable are the sculptural works created by late Susanne Wenger (an Austrian) and her New Sacred Art Movement in Osun-Osogbo Sacred Grove, which gave meaning to open spaces within the grove. This paper examines the role played by these artworks to project Nigeria to the global art world. The benefits to Nigeria and the global art traditions and recommendations on how to revive this dwindling economic resource will also be examined. The approach used was to study the artworks produced by some of these artists. Some of the findings were that the works were carefully done with suitable materials that have withstood climate change.

This book investigates the coming-of-age genre as a significant phenomenon in New Zealand’s national cinema, tracing its development from the 1970s to the present day. A preliminary chapter identifies the characteristics of the coming-of-age film as a genre, tracing its evolution and the influence of the French New Wave and European Art Cinema, and speculating on the role of the genre in the output of national cinemas. Through case studies of fifteen significant films, including The God Boy, Sleeping Dogs, The Scarecrow, Vigil, Mauri, An Angel at My Table, Heavenly Creatures, Once Were Warriors, Rain, Whale Rider, In My Father’s Den, 50 Ways of Saying Fabulous, Boy, Mahana, and Hunt for the Wilderpeople, subsequent chapters examine thematic preoccupations of filmmakers such as the impact of repressive belief systems and social codes, the experience of cultural dislocation, the expression of a Māori perspective through an indigenous “Fourth Cinema,” bicultural relationships, and issues of sexual identity, arguing that these films provide a unique insight into the cultural formation of New Zealanders. Given that the majority of films are adaptations of literary sources, the book also explores the dialogue each film conducts with the nation’s literature, showing how the time frame of each film is updated in a way that allows these films to be considered as a register of important cultural shifts that have occurred as New Zealanders have sought to discover their emerging national identity.

Existing research has consistently shown that perceptions of the potential economic consequences of Scottish independence are vital to levels of support for constitutional change. This paper attempts to investigate the mechanism by which expectations of the economic consequences of independence are formed. A hypothesised causal micro-level mechanism is tested that relates constitutional preferences to the existing skill investments of the individual. Evidence is presented that larger skill investments are associated with a greater likelihood of perceiving economic threats from independence. Additionally, greater perceived threat results in lower support for independence. The impact of uncertainty on both positive and negative economic expectations is also examined. While uncertainty has little effect on negative expectations, it significantly reduces the likelihood of those with positive expectations supporting independence. Overall, it appears that a general economy-wide threat is most significant, and it is conjectured that this stems a lack of information on macroeconomic governance credentials.

This paper offers a critique of transnational aspects of ‘inclusion,’ one of those global education buzzwords that as Slee (2009) puts it, say everything but say nothing. It starts off by trying to compare Indian and English usages and attitudes at the level of teacher discourse, and notes the impossibility of any ‘authentic’ translation, given the very different cultural contexts and histories. In response to these divergences, the authors undertake a much more genealogical and ‘forensic’ examination of values associated with ‘inclusion,’ focussing especially on a key notion of ‘pity.’ The Eurocentric tradition is traced from its Platonic origins through what is claimed to be the ‘industrialization of pity’ and its rejection as a virtue in favour of more apparently egalitarian measures of fairness. The Indian tradition relates rather to religious traditions across a number of different belief systems, most of which centre on some version of a karmic notion of pity. The authors both criticise and reject ‘inclusion’ as a colonisation of the global and call for a new understanding of notions like ‘pity’ as affective commitment rather than ‘fair’ dispensation of equality.

In recent years as public in general and specialist have been showing big interest to the matters of reading. According to discussion and launch of the “Support and Development of Reading National Program”, many Russian libraries are organizing the large-scale events like marathons, lecture cycles, bibliographic trainings etc. which should draw attention of different social groups to reading. The individual forms of attraction to reading are used much rare. To author’s mind the main reason of such an issue has to be the lack of information about forms and methods of attraction to reading.
