Professional development of social work in Russia

The aim of the paper was to get an understanding about how the profession of social work explains its relevance and legitimacy in today's Russia, to enlighten the importance of socio-political, professional and educational contexts in explaining the societal position of the social work profession in Russia. This paper begins with the analysis of the processes of legitimization, professionalization and constitution of social work in today's Russia. In addition to functionalist and critical perspectives on these three processes, in its second part the paper employs phenomenological approach looking into everyday life theory of social work that is constructed in routine work at the social service agencies. The third part of this paper talks about the issues of social services and social work with family and children in contemporary Russia.

‘Continue or terminate?’ Determinants of long-term volunteering in sports clubs

This study analyzed the determinants underlying sports club volunteers' tendencies to continue or terminate their long-term commitment to volunteering in order to help sports clubs improve their volunteer management. Their risk of terminating was viewed in terms of subjective expectations and evaluations (satisfaction) regarding club-related working conditions and normative commitments (solidarity) to the sports club. These relationships were tested empirically with an online questionnaire of 441 sports club volunteers in a selection of 45 Swiss sports clubs. Results showed that the constructs orientation toward collective solidarity and volunteer job satisfaction correlated positively with long-term volunteering commitment. The effect of the former was stronger than that of the latter. Volunteers with a higher orientation toward collective solidarity were unlikely to terminate their voluntary engagement in their club. The discussion presents recommendations to help clubs retain volunteers.

Analyzing PL/1 Legacy Ecosystems: An Experience Report

This paper presents a case study of analyzing a legacy PL/1 ecosystem that has grown for 40 years to support the business needs of a large banking company. In order to support the stakeholders in analyzing it we developed St1-PL/1 — a tool that parses the code for association data and computes structural metrics which it then visualizes using top-down interactive exploration. Before building the tool and after demonstrating it to stakeholders we conducted several interviews to learn about legacy ecosystem analysis requirements. We briefly introduce the tool and then present results of analysing the case study. We show that although the vision for the future is to have an ecosystem architecture in which systems are as decoupled as possible the current state of the ecosystem is still removed from this. We also present some of the lessons learned during our experience discussions with stakeholders which include their interests in automatically assessing the quality of the legacy code.

Internationale Schiedsgerichtsbarkeit der Schweiz: vom Forum running zum judgment running?

Zum 65. Geburtstag von Prof. Dr. iur. et lic. oec. Heinrich Koller, haben über 40 Mitarbeiterinnen und Mitarbeiter des Bundesamtes für Justiz (BJ) eine Festschrift für ihren scheidenden Direktor verfasst. Die in deutscher und französischer Sprache verfassten Beiträge spiegeln das breite Spektrum einer Institution, aus deren «atelier» manch ein Gesetzesentwurf stammt. Oft übersehen wird dabei, dass das BJ aber auch eine «Werkstatt» ist, die das geltende Recht umsetzt und im Rahmen dieser Konkretisierung wichtige Akzente setzt. Die Festschrift bietet damit einen Blick hinter die Kulissen eines wichtigen Kompetenzzentrums für Rechtsfragen und beleuchtet aktuelle Probleme aus «erster Hand». Abgerundet wird die Festschrift mit einem Grusswort des Vorstehers EJPD (Bundesrat Christoph Blocher) und einem Schriftenverzeichnis von Heinrich Koller. Enthalten ist unter Anderem - die Bundesverfassung - weitere wichtige Gesetze und Verordnungen aus dem öffentlichen Recht - ZGB und Nebenerlasse - OR und Nebenerlasse - Erlasse zum Strafrecht und zur Strafrechtspflege - Gesetze zu Gesundheit, Arbeit und sozialer Sicherheit - wichtige Gesetze zu Wirtschaft und Kredit Autorinnen und Autoren Mitarbeiterinnen und Mitarbeiter des Bundesamtes für Justiz

Multidrug resistance protein 4 (MRP4) expression in prostate cancer is associated with androgen signaling and decreases with tumor progression

Multidrug resistance protein 4 (MRP4) is a transmembrane transport protein found in many cell types and is involved in substrate-specific transport of endogenous and exogenous substrates. Recently, it has shown to be expressed in prostate cancer cell lines and to be among the most commonly upregulated transcripts in prostate cancer, although a comprehensive expression analysis is lacking so far. We aimed to investigate its expression by immunohistochemistry in a larger cohort of neoplastic and nonneoplastic prostate tissues (n = 441) and to correlate its expression with clinicopathological parameters including PSA-free survival times and molecular correlates of androgen signaling (androgen receptor (AR), prostate-specific antigen (PSA), and forkhead box A (FoxA)). MRP4 is widely expressed in benign and neoplastic prostate epithelia, but its expression gradually decreases during tumor progression towards castrate-resistant disease. Concordantly, it correlated with conventional prognosticators of disease progression and-within the group of androgen-dependent tumors-with AR and FoxA expression. Moreover, lower levels of MRP4 expression were associated with shorter PSA relapse-free survival times in the androgen-dependent group. In benign tissues, we found zone-dependent differences of MRP4 expression, with the highest levels in the peripheral and central zones. Although MRP4 is known to be regulated in prostate cancer, this study is the first to demonstrate a gradual downregulation of MRP4 protein during malignant tumor progression and a prognostic value of this loss of expression.

Improving backdrivability in geared rehabilitation robots

Many rehabilitation robots use electric motors with gears. The backdrivability of geared drives is poor due to friction. While it is common practice to use velocity measurements to compensate for kinetic friction, breakaway friction usually cannot be compensated for without the use of an additional force sensor that directly measures the interaction force between the human and the robot. Therefore, in robots without force sensors, subjects must overcome a large breakaway torque to initiate user-driven movements, which are important for motor learning. In this technical note, a new methodology to compensate for both kinetic and breakaway friction is presented. The basic strategy is to take advantage of the fact that, for rehabilitation exercises, the direction of the desired motion is often known. By applying the new method to three implementation examples, including drives with gear reduction ratios 100-435, the peak breakaway torque could be reduced by 60-80%.

Role of the B1 short arm in laminin self-assembly

Laminin self-assembles into a basement membrane polymer through specific low-affinity interactions. Recently, it was shown that the terminal short-arm domain (domains VI and V) of the B1 chain (fragment E4) possesses one of the laminin self-interaction sites [Schittny, J.C. & Yurchenco, P.D. (1990) J. Cell Biol. 110, 825-832], but that the binding partner(s) of this domain is unknown. Using affinity retardation chromatography we now investigate the domain(s) fragment E4 binds to. The elution of E4 was clearly retarded on immobilized laminin and fragment E1' (three-chain short-arm complex excluding the distal part of the B1 chain), but not on immobilized E4 in calcium containing buffer and at 37 degrees C. Under the same conditions, E1' strongly interacts with immobilized E4. In addition, E1' is able to non-covalently cross-link soluble E4 to immobilized E4. No further interaction of laminin and E4 with additional fragments (P1', A, B2 and B1 chain short-arm complex without B1-domains VI-IV and without globules; E8, distal long arm and G1-3; E3, long-arm G subdomains 4 and 5) could be demonstrated. These data are interpreted as evidence that (a) the primary laminin-laminin bonds are formed between the short arms of laminin, that (b) the terminal B1 short-arm domain (E4) can interact with the short arm(s) of the A and/or B2 chain(s) (domain E1'), but does not self-interact, and that (c) due to at least three self-binding sites, laminin polymerization behaves co-operatively.
