Th is article responds to recent calls for experimental research into the relationship between public service motivation (PSM) and job performance. Th e author conducted a fi eld experiment with a sample of nurses at a public hospital in Italy to investigate the interplay between job performance, PSM, and two conditions: exposure to contact with benefi ciaries and self-persuasion interventions....

This paper presents a mechanism that improves the energy efficiency of PSM (Power Saving Mechanism) specified for DCF (Distributed Coordination Function) in IEEE 802.11. In PSM, time is divided into beacon intervals. At the start of each beacon interval, every node stays awake for a duration, called the ATIM Window. During the ATIM window, nodes exchange control packets to determine whether the...

microscopy. Quantitative analysis of the movies revealed a clear posterior-to-anterior gradient of cell motility and directionality in the PSM. We tracked the movement of the PSM extracellular matrix (ECM) in parallel to the labelled cells and substracted the ECM movement to the global motion of cells. After substraction, cell movements remained consistently graded but lacked directionality. Th...

Raising software abstraction and re-use levels are key success factors for producing quality software products. Modeldriven architecture (MDA) is an OMG initiative following this trend by mapping a conceptual model of application specified in platform independent model (PIM), to one or more platform specific models (PSM) automatically. Because there is little previous work tackling the developm...

Recently, a novel Mr 100,000 prostate-specific membrane glycoprotein (PSM) has been detected by the prostate-specific monoclonal antibody 7Ell-C5, raised against the human prostatic carcinoma cell line LNCaP. The PSM antigen is expressed exclusively by normal and neoplastic prostate cells and metastases. We now report the molecular cloning of a full-length 2.65-kilobase complementary DNA encodi...

Im Erwerbsobstbau ist der Einsatz von Pflanzenschutzmitteln (PSM) zum Erhalt des Ertrags und zur Erfüllung der hohen Qualitätsstandards unabdingbar. Dabei kann es bei Lücken in der Laubwand zu ungewollten Einträgen von PSM in den Naturhaushalt kommen. Sensorsysteme bieten die Möglichkeit sowohl die Zielfläche als auch Lücken gezielt zu erkennen und somit eine bedarfsgerechte Applikation durch S...

This paper introduces how to apply OMG’s Model-Driven Architecture (MDA) to develop a cross-platform workflow solution. A workflow solution first is modeled as a PIM Platform Independent Model model. The PIM model will be translated into a PSM (Platform Specific Model) model according to the selected workflow platform and then the corresponding process definition is automatically generated. I...

This article argues that OR interventions, particularly problem structuring methods (PSM), are complex events that cannot be understood by conventional methods alone. In this paper an alternative approach is introduced, where the units of analysis are the activity systems constituted by and constitutive of PSM interventions. The paper outlines the main theoretical and methodological concerns th...

A public service motivation (PSM) inclines employees to provide effort out of concern for the impact of that effort on a valued social service. Though deemed to be important in the literature on public administration, this motivation has not been formally considered by economists. When a PSM exists, this paper establishes conditions under which government bureaucracy can better obtain PSM motiv...

For Diagnostic Problem Solving Methods, appropriate methods and knowledge bases require considerable time for development. Graphical knowledge interfaces and reuse of Problem Solving Methods (PSM) can increase user performance of building knowledge bases. Furthermore classiication accuracy is also imporant which can be increased by combinations of diierent PSM. We combined three algorithms of t...
