The Financial Rate of Profit: What Is It, and How Has It Behaved in the United States?

This work contributes to the almost nonexistent literature on the profit rate of the financial sector. It updates the single study to include financial variables to cover the past decade, compares this profit rate to the (almost unpublished) Weisskopf and NIPA financial profit rates, compares the financial and nonfinancial sector rates, and details the procedure to construct the profit rate in the financial sector including relevant financial variables which capitalists consider to make profit-rate decisions.

Comparison of the effects of cetylpyridinium chloride with an essential oil mouth rinse on dental plaque and gingivitis - a six-month randomized controlled clinical trial

OBJECTIVE: To compare the effects of an experimental mouth rinse containing 0.07% cetylpyridinium chloride (CPC) (Crest Pro-Health) with those provided by a commercially available mouth rinse containing essential oils (EOs) (Listerine) on dental plaque accumulation and prevention of gingivitis in an unsupervised 6-month randomized clinical trial. MATERIAL AND METHODS: This double-blind, 6-month, parallel group, positively controlled study involved 151 subjects balanced and randomly assigned to either positive control (EO) or experimental (CPC) mouth rinse treatment groups. At baseline, subjects received a dental prophylaxis procedure and began unsupervised rinsing twice a day with 20 ml of their assigned mouthwash for 30 s after brushing their teeth for 1 min. Subjects were assessed for gingivitis and gingival bleeding by the Gingival index (GI) of Löe ; Silness (1963) and plaque by the Silness ; Löe (1964) Plaque index at baseline and after 3 and 6 months of rinsing. At 3 and 6 months, oral soft tissue health was assessed. Microbiological samples were also taken for community profiling by the DNA checkerboard method. RESULTS: Results show that after 3 and 6 months of rinsing, there were no significant differences (p=0.05) between the experimental (CPC) and the positive control mouth rinse treatment groups for overall gingivitis status, gingival bleeding, and plaque accumulation. At 6 months, the covariant (baseline) adjusted mean GI and bleeding sites percentages for the CPC and the EO rinses were 0.52 and 0.53 and 8.7 and 9.3, respectively. Both mouth rinses were well tolerated by the subjects. Microbiological community profiles were similar for the two treatment groups. Statistically, a significant greater reduction in bleeding sites was observed for the CPC rinse versus the EO rinse. CONCLUSION: The essential findings of this study indicated that there was no statistically significant difference in the anti-plaque and anti-gingivitis benefits between the experimental CPC mouth rinse and the positive control EO mouth rinse over a 6-month period.

Pulp and periodontal healing of laterally luxated permanent teeth: results after 4 years

AIM: To evaluate the pulp and periodontal healing of laterally luxated permanent teeth. MATERIAL AND METHODS: Patients presenting with lateral luxation of permanent teeth during 2001-2002 were enrolled in this clinical study. Laterally luxated teeth were repositioned and splinted with a TTS/composite resin splint for 4 weeks. Immediate (prophylactic) root-canal treatment was performed in severely luxated teeth with radiographically closed apices. All patients received tetracycline for 10 days. Re-examinations were performed after 1, 2, 3, 6, 12 and 48 months. RESULTS: All 47 laterally luxated permanent teeth that could be followed over the entire study period survived. In 10 teeth (21.3%), a prophylactic root-canal treatment was performed within 2 weeks following injury. The remaining 37 teeth showed the following characteristics at the 4-year re-examination: 19 teeth (51.4%) had pulp survival (no clinical or radiographic signs or symptoms), nine teeth (24.3%) presented with pulp canal calcification, and pulp necrosis was seen in another nine teeth (24.3%), within the first year after trauma. None of the teeth with a radiographically open apex at the time of lateral luxation showed complications. External root resorption was only seen in one tooth. CONCLUSIONS: Laterally luxated permanent teeth with incomplete root formation have a good prognosis, with all teeth surviving in this study. The most frequent complication was pulp necrosis that was only seen in teeth with closed apices.

Performance-Based Engineering Framework for Earthquake and Fire Following Earthquake

The objective for this thesis is to outline a Performance-Based Engineering (PBE) framework to address the multiple hazards of Earthquake (EQ) and subsequent Fire Following Earthquake (FFE). Currently, fire codes for the United States are largely empirical and prescriptive in nature. The reliance on prescriptive requirements makes quantifying sustained damage due to fire difficult. Additionally, the empirical standards have resulted from individual member or individual assembly furnace testing, which have been shown to differ greatly from full structural system behavior. The very nature of fire behavior (ignition, growth, suppression, and spread) is fundamentally difficult to quantify due to the inherent randomness present in each stage of fire development. The study of interactions between earthquake damage and fire behavior is also in its infancy with essentially no available empirical testing results. This thesis will present a literature review, a discussion, and critique of the state-of-the-art, and a summary of software currently being used to estimate loss due to EQ and FFE. A generalized PBE framework for EQ and subsequent FFE is presented along with a combined hazard probability to performance objective matrix and a table of variables necessary to fully implement the proposed framework. Future research requirements and summary are also provided with discussions of the difficulties inherent in adequately describing the multiple hazards of EQ and FFE.

Dalle sfide interculturali, al “romanzo”, al progetto socio educativo integrato

Intercultural challenge, “tale” and social educational strategy, Rome, November 2006: Police and Teachers deal differently with a little group of travellers. The analysis of this recent episode shows that intercultural issues are the basis of the educational commitment of the teachers but also of the prejudice of police and other people looking from outside to the relationship between teachers and travellers. The paradox of a double ethic concerning travellers needs to be deconstructed by the antiracist approach based on children rights. At the same time educational intervention cannot deal efficiently with emergency situations concerning children without cooperation with social work. The article underlines the role of democratic educational institutions in the developing appropriated strategies in dealing with complexes social issues which are not just to be “culturalised”.

Changing ‘Multi-Problem Families’ – Developing a Multi-Contextual Systemic Approach

Over the past 30 years the Marlborough Family Service in London has pioneered multi-family work with marginalized families presenting simultaneously with abuse and neglect, family violence, substance misuse, educational failure and mental illness. The approach is based on a systemic multi-contextual mode and this chapter describes the evolving work, including the establishment of the first permanent multiple family day setting, specifically designed for and solely dedicated to the work with seemingly ‘hopeless’ families. The ingredients of ‘therapeutic assessments’ of parents and families are outlined and the importance of initial network meetings with professionals and family members is emphasized.

Between Equity and Empathy: Social Professions and the New Accountability

This article explores the practical and ethical implications of the ‘new accountability’ (working to procedures, targets and standards) based on interviews with British social professionals. Although similar tendencies are present in other European countries, in Britain the rule-bound nature of social work is more intense. Practitioners who regard the ‘new accountability’ positively justify their views with reference to utilitarian and rights-based arguments relating to the promotion of good outcomes, the achievement of equity, respecting the consumer rights of service users and the rights of other stakeholders to information and value for money. Those practitioners who view the new accountability requirements negatively seem to speak in a different ‘moral voice’, which can be linked to more personal and situated approaches to ethics, stressing the importance of particular relationships in context, trust, sensitivity and a sense of ‘vocation’. Both ‘voices’ are part of professional practice, but the new accountability stresses the former at the expense of the latter. For social work to play the critical role identified by Walter Lorenz, maintaining a creative balance between equity and empathy will be important.

The Current Discussion on Men and Masculinities

In the past gender specific problems were mainly discussed in a female perspective. In the meantime there is a rising attentiveness in the living conditions of men and their coping strategies within critical life events. In this paper an appropriate frame of reference is outlined which can be used in those areas of social work where men are already discovered as a target group with special difficulties and needs.

Il razzismo della prosperità nell’Europa contemporanea - Riflessioni a margine del pensiero antirazzista di Walter Lorenz

Recent publishing on the migration phenomena in the communitarian and globalized Europe, puts in evidence a fundamental racism which is capable of making cultural processes grow and feed both chaos and social disorder. As a matter of fact we are approaching the ending debates on multicultural citizenship as well as on solidary integration and antiracism. Since the appearing of these phenomena, namely the huge post colonial migration in the nineteen-eighties, by which the colonized countries became almost “emigrant nurseries”, one could expect their stabilization. On the contrary, globalization and migration (twin subjects) everywhere still produce, at various levels, social disturbances together with some chauvinistic limitations as an ultimate kind of western prosperity defense. The peculiar European features of this new racism, less than ideological (superiority, homogeneity and civilizing mission), are confined to the concepts of patriotism, inequality and exclusion. In these terms one can understand why the new economic expansionism and the quest for new world markets makes European policies unstable, which remain undecided between conservatism, liberalism and extreme right. All this explains at least two things: the existing ambiguities of some European policies aiming to enhance particular forms of protectionism, and the difficulties in which the antiracist thought seems to be embedded. Indeed, according to what Walter Lorenz has already made clear, by using a well founded methodology, which prevents any fruitless protestations, it is impossible to contrast racism and nationalism. In such context, the educational field should try to use an operative epistemology. In other words the antiracist thought should dispose of competences and skills and, especially, personal and reflective capabilities. All this in order to avoid that which, in different historical scenes, permit the revival of the sense of moral opprobrium could not be identified with the political alibi to maintain privileges as well as advantages for the exclusive benefit of wealthy countries.

Europeanization Process in Italian Social Work Education

The article shows the process of Europeanization of the Italian social work education. After a brief excursus of the development of social work education in Italy, the paper presents the experiences made in the context of Socrates Erasmus project. Considering the results of the Thematic Network in Social Work organised by Parma University, some reflections are presented on the effects of Europeanization both respect the teachers and the students.

Social Work, Political Violence and Historical Change:

In this paper the author outlines the background to the history of the conflict in Northern Ireland which led to the current ‘Troubles’. In this discussion a range of key ideas are highlighted, including the nature of sectarianism and patterns of violence which have profoundly affected the society. The second part of the paper reviews a number of issues which face social workers when they try to deal with the effects of such violence as well as highlighting new challenges which have emerged as the society moves towards the resolution of conflict. It concludes with the argument that, wherever there is such conflict in the world, social workers need critically to understand the way in which political and social structures impinge upon their everyday practice.
