Secure communication : CDS, PIR, PSM
Private Information Retrieval is the problem of querying two servers to nd a value in a database, while keeping the index private. We extend this problem to Generalized Wildcard PIR, where we instead query an aggregate of the entries whose indices match a pattern, called a generalized wildcard, …

Prevention sequence mechanisms (PSM) for Near Earth Objects (NEOs) based on a three parameter scheme based classification framework
… to a set of Prevention Sequence Mechanisms (PSM) which represent a specific sequence of deterrence mechanisms. Potentially dangerous NEOs were classified into various groups that were derived from three different classes based on NEO size, Time-to-Impact (TTI) and chemical composition. For …

Thou shall not flow: assessing magnitudes and processes of dissolved reactive phosphorus (P) removal by P-sorbing materials
… to capture DRP losses. Phosphorus-sorbing media (PSM), waste by-products with high P removal potential, are the basis of P removal structures. The ability of PSM to remove DRP depends on the physical and chemical properties of the PSM, but the estimated DRP removal potential depends on the method …

Sexual misconduct in police officers: development of a risk assessment tool for the early identification of police officers and staff who abuse their positions for a sexual purpose.
Sexual misconduct in police officers (PSM) is a form of police corruption which although rare, has a detrimental impact on police reputation and adverse outcomes for victims. PSM often involves targeting of vulnerable people and officers abusing the authority of their role for sexual gain. …

Investigating the relationship between clock gene stability and the pace of the vertebrate segmentation clock
… they ‘pinch’ away from the pre-somitic mesoderm (PSM) with a species-specific periodicity, coinciding with waves of cycling mRNA expression of ‘clock’ genes sweeping across the PSM that are regulated by a molecular oscillator. Mathematical models suggest that sustained rapid oscillations of …

Public service motivation and volunteering.
… rationale behind public service motivation (PSM). I address the debate of how it affects volunteer behavior through the concept of volunteering intensity. As individuals often have preconceived notions as to how their values match with an organization, I integrate the theory of Person- …

The Impact of Public Service Motivation on Reentry Managers' Decision-making Practices
… the effects of public service motivation (PSM) in predicting decision-making of criminal justice personnel (reentry managers) in the management of former prisoners. The overarching research question seeks to answer if, and in what way, PSM score influences reentry managers' approach to …

A Comparative Study of Public Service Motivation Among Organizational Units in a Public University
… study examined public service motivation (PSM) to determine if it differed among the staff in the three units of the Division of Student Affairs in a large, public university. Quantitative and qualitative methods were used to analyze differences in PSM among the three work units: …

An Investigation on the Effectiveness of a Problem Structuring Method in a Group Decision-Making Process
… a group consensus. Problem Structuring Methods (PSM) are the collections of participatory modeling methods that aim to tackle a messy problem. Despite the positive reports, literature indicates some challenges and criticisms of the effectiveness of PSM applications. One of the main challenges is …

Effekte einer reduzierten Dosis von Pflanzenschutzmitteln auf tritrophische Systeme im Ackerbau
Chemische Pflanzenschutzmittel (PSM) bekämpfen nicht nur Schadorganismen, sondern haben aufgrund ihrer hohen Toxizität auch negative Auswirkungen auf Nicht-Ziel-Organismen. Die Fragestellung der Arbeit war es, ob mit reduzierten Anwendungen von PSM ihr Gefährdungspotenzial für Prädatoren von …

Novel Notch signalling dynamics within the molecular oscillator underlying vertebrate segmentation
… of the embryo termed the pre-somitic mesoderm (PSM). This periodicity is regulated by a molecular oscillator underlain by negative feedback loops termed the ‘segmentation clock,’ which manifests as a dynamic pattern of gene expression that sweeps the PSM in a caudo-rostral direction. Key …

THE ROLE OF THE PARTNER SWITCHING MECHANISM IN REGULATION OF THE CHLAMYDIAL DEVELOPMENTAL CYCLE
… the pan-chlamydial partner switching mechanism (PSM) is involved in RB to EB morphogenesis through the conversion of external signals into phenotypic changes via regulation of sigma28. The putative chlamydial PSM is composed of two sensor phosphatases (SPs: RsbU and CTL0852), two anti-anti-sigma …

Analysis of the Zebrafish Segmentation Clock
… tissue called the presomitic mesoderm (PSM) by a process called somitogenesis. <br></br><br></br> Underlying the periodicity of somitogenesis are transcriptional oscillations of cyclic genes in the cells of the PSM. On a tissue level, these oscillations manifest as travelling waves, …

The role of pax genes in vertebrate segmentation
… that Pax3/7 drives precocious differentiation of PSM towards the myogenic lineage, as well as inducing a range of morphological changes in PSM tissue. These changes include alterations in the cytoskeleton, cell adhesion, and extracellular matrix formation.

The Motivation of Voluntary Sector Employees: A Study of the Relevance of Public Service Motivation
This thesis uses Public Service Motivation (PSM) as a mechanism to explore the values and motivations of voluntary sector employees. It does so in the context of increased outsourcing of public service delivery to the voluntary sector and questions regarding the existence of distinctive motivations …
