description: Για κάθε επιχείρηση και οργανισμό, δημόσιο ή ιδιωτικό, το ανθρώπινο δυναμικό αποτελεί ένα ισχυρό θεμέλιο, μια βασική κινητήρια δύναμη, εκφράζοντας την οικονομική αξία που απαιτείται για την εκπλήρωση των στόχων μέσα σε ένα περιβάλλον που συνεχώς μεταβάλλεται και εξελίσσεται. Είναι ένα πολύτιμο και χρήσιμο παραγωγικό κεφάλαιο που διαφοροποιεί τις επιχειρήσεις και τους οργανισμούς, επηρεάζει την παραγωγικότητά τους και μέσα από τον σωστό σχεδιασμό και την οργάνωσή του καθορίζει την επιτυχία και την ανάπτυξη. Η Δημόσια Διοίκηση οφείλει να ικανοποιεί τις ανάγκες των πολιτών-διοικουμένων, να παρακολουθεί και να προσαρμόζεται στις αλλαγές και στις κοινωνικο-οικονομικές και τεχνολογικές εξελίξεις επανεξετάζοντας και βελτιώνοντας δομές και διαδικασίες. Η σύγχρονη δημόσια διοίκηση απαιτεί καλλιέργεια μιας κουλτούρας οργάνωσης που θα εστιάζει στην συνεχιζόμενη μάθηση και σε πρακτικές που θα στηρίζονται σε αξίες και ηθικές συμπεριφορές στο εργασιακό περιβάλλον ώστε να επιτευχθεί κοινωνική συνοχή και ευημερία. Η ποιότητα της δημόσιας διοίκησης είναι αποφασιστική και καθοριστική για την κοινωνική ευημερία και την οικονομική ανάπτυξη μιας χώρας. Η εκπαίδευση και η επιμόρφωση των δημοσίων υπαλλήλων, ως μια οργανωμένη και σωστά σχεδιασμένη διαδικασία, αποκτά ιδιαίτερη σημασία και διαδραματίζει καθοριστικό ρόλο στην ανάπτυξη και εξέλιξή τους, στη βελτίωση των ικανοτήτων και των δεξιοτήτων τους και στην επίτευξη της γενικότερης απόδοσης κατά την άσκηση των καθηκόντων τους, μέσα από μια γενικότερη προσπάθεια εκσυγχρονισμού και μεταρρύθμισης στη δημόσια διοίκηση.

description: Radiofrequency vortex spin-transfer oscillators based on magnetic tunnel junctions with very low resistance area product were investigated. A high power of excitations has been obtained characterized by a power spectral density containing a very sharp peak at the fundamental frequency and a series of harmonics. The observed behaviour is ascribed to the combined effect of spin transfer torque and Oersted-Ampère field generated by the large applied dc-current. We furthermore show that the synchronization of a vortex oscillation by applying a ac bias current is mostly efficient when the external frequency is twice the oscillator fundamental frequency. This result is interpreted in terms of a parametric oscillator.

Institutional Responses to State Merit Aid Programs: The Case of Florida Community Colleges

description: This study estimates the effects of a state merit aid program on community colleges by using the introduction of the Florida Bright Futures Scholarship program as a natural experiment. It examines the effects of the program in terms of institutional aid, tuition pricing, and as a re-sorting mechanism for high ability students. The results suggest that community colleges do not increase students' charges to capture additional revenues, nor do they substitute state aid for institutional aid. Contrary to what was expected, institutions apparently use the scholarship program as an "ability marker" to provide additional financial aid to high ability students. Although we find no statistical evidence that the community college system is losing high ability students, there is strong support for heterogeneity in the program effect across institutions that depends on measures of the level of competition within each college's educational marketplace.

description: The low temperature electrical behavior of adjacent silicide/Si Schottky contacts with or without dopant segregation is investigated. The electrical characteristics are very well modeled by thermionic-field emission for non-segregated contacts separated by micrometer-sized gaps. Still, an excess of current occurs at low temperature for short contact separations or dopant-segregated contacts when the voltage applied to the device is sufficiently high. From two-dimensional self-consistent non-equilibrium Green's function simulations, the dependence of the Schottky barrier profile on the applied voltage, unaccounted for in usual thermionic-field emission models, is found to be the source of this deviation.

description: Tuberculosis (TB) preventive therapy is an integral part of global strategies to end TB. Isoniazid preventive therapy (IPT) is currently the only regimen recommended globally for low-resource settings with high burdens of TB and TB-HIV. In South Africa, where the incidence of TB and TB-HIV are among the highest in the world, health districts were quick to facilitate access to six-month IPT in the absence of active TB symptoms for all people living with HIV, amid numerous unknowns. My doctoral thesis responds to some of these unknowns; specifically, the effectiveness of IPT to reduce TB incidence and its acceptability in communities where latent TB infection was previously unfamiliar. The research occurred within a community-based participatory research framework including regular meetings with grassroots community advisory teams in three communities of uMgungundlovu District, KwaZulu-Natal. IPT effectiveness was evaluated utilising a retrospective cohort design, comparing TB incidence across two years among people receiving IPT alone, antiretroviral therapy (ART) alone, or IPT+ART to those without intervention. Acceptability was evaluated utilising the ethnographic method, including extensive field work, eight group interviews to learn about perspectives of TB infection, disease and IPT, and nine individual interviews with people accepting, discontinuing or declining IPT to learn about IPT experiences and decision making. Among those who completed the regimen, IPT significantly reduced the two-year TB incidence by 100% among women (97.5%CI=78-100%), with a less certain effect among men: IR=0.46, 95%CI=0-85%. IPT also appeared to provide additional prevention for people on ART. Nevertheless, IPT was interpreted by some as dangerous when the costs related to pill collection or consumption exacerbated poverty, the stigma associated with HIV and ART were conflated with its use, or it was seen as toxic. Clinical expectations of IPT initiation and adherence may also conflict with expectations of women in Zulu culture. Some women may initiate IPT to please the healthcare provider, rather than from a belief in preventive benefits. Taken together, findings suggest that IPT can reduce the risk of TB among people living with HIV, but may not be a high priority when economic and social needs compete.

Community colleges

description: As community colleges search for models of organizational success, new attention is being paid to technical colleges—institutions that primarily offer terminal programs in specific career-related fields rather than focusing on more general academic credentials and transfer programs as many comprehensive institutions do. Recent research observes that in some states, technical colleges have substantially higher completion rates than do comprehensive community colleges. Yet there is scant research available that systematically compares similar students in similar programs at technical and comprehensive colleges. This study uses administrative data from Washington State to compare the outcomes of young, career-technical students across institutions, with and without extensive controls for student characteristics, educational intent, and area of study. This generates three key findings: first, technical and comprehensive colleges tend to serve quite different populations, so a true apples-to-apples comparison requires limiting the analysis to a relatively small fraction (less than 10%) of students enrolled at either institution. Second, at least for this limited subset of career-technical students, technical schools have significantly higher certificate completion rates after three years, with no apparent deficit in associate degree completion. Our third main finding is that the differences in student outcomes within the two types of schools are much larger than differences between them. Even within this limited group, institution type alone explains a relatively small fraction of the overall variation in student outcomes across institutions. It would thus be unwise for research and policymakers to fixate on this one dimension of difference.

(Un)learning citizenship in Canada : Iranian immigrant youth's silences, contradictions, and expressions
Creators: name: Nabavi, Maryam
Publisher: name: University of British Columbia
Year: 2011

description: This study examines the meanings, interpretations, and experiences of citizenship in the lives of young Iranian immigrants in Canada in order to (1) offer a conceptual approach to migrant youth citizenship that fills gaps in dominant conceptualizations of citizenship in Canada, and (2) provide recommendations for the improvement of models of citizenship education relevant to lived experiences of migrant youth. Contemporary conceptions of citizenship in Canada are underpinned by assumptions closely aligned with a multicultural national identity and stress formal aspects of citizenship, which undermine substantive aspects of citizenship. Moreover, citizenship education is traditionally conveyed within formal schooling contexts, thereby neglecting the informal processes of learning citizenship for immigrants. To address these weaknesses, this study examines how citizenship is learned within and across diverse informal sites for Iranian immigrant youth. This understanding helps to situate more effective approaches to education that account for culture, locality, and the social, and political contexts in which learners are embedded. In 2010, I conducted a six-month ethnographic study with 12 first-generation immigrant Iranian youths aged 19-30 in Vancouver, Canada. Analysis of semi-structured interviews and participant observation disclosed citizenship as a process of learning within individuals’ lived experiences. In-depth engagement with the research findings, informed by concepts associated with cultural studies, diaspora studies, and cultural citizenship, reveal three conceptual commitments that aid understanding of citizenship and learning for citizenship: (1) identity as situated within multiple, shifting, intersecting, and interlocking dimensions; (2) citizenship as situated within multiple constructed boundaries of membership; and (3) citizenship as an iterative process of learning. This inductive framework situates citizenship discourse within the national and global contexts in which immigrant youth are embedded. This study contributes to theoretical and empirical literature on substantive and social citizenship and citizenship learning for immigrant youth in formal and informal contexts. It also offers practical recommendations for improving models of learning citizenship within formal schooling contexts by including: a conceptual commitment to move beyond a nation-based focus on citizenship, a curricular commitment to focus on the lived experiences of learners, and a pedagogical commitment to focus on informal and experiential modes of learning.

description: The dataset in the present article provides information on protozoic silicon (Si) pools represented by euglyphid testate amoebae (TA) in soils of initial and forested biogeosystems. Protozoic Si pools were calculated from densities of euglyphid TA shells and corresponding Si contents. The article also includes data on potential annual biosilicification rates of euglyphid TA at the examined sites. Furthermore, data on selected soil parameters (e.g., readily-available Si, soil pH) and site characteristics (e.g., soil groups, climate data) can be found. The data might be interesting for researchers focusing on biological processes in Si cycling in general and euglyphid TA and corresponding protozoic Si pools in particular.

description: At open-access two-year public colleges, the goal of the traditional assessment and placement process is to match incoming students to the developmental or college-level courses for which they have adequate preparation; the process presumably increases underprepared students’ chances of short- and long-term success in college while maintaining the academic quality and rigor of college-level courses. However, the traditional process may be limited in its ability to achieve these aims due to poor course placement accuracy and inconsistent standards of college readiness. To understand current approaches that seek to improve the process, we conducted a scan of assessment and placement policies and practices at open-access two-year colleges in Georgia, New Jersey, North Carolina, Oregon, Texas, Virginia, and Wisconsin. We describe the variety of approaches that systems and colleges employed to ameliorate poor course placement accuracy and inconsistent standards associated with the traditional process. Taking a broad view of the extent of these approaches, we find that most colleges we studied adopted a measured approach that addressed a single limitation without attending to other limitations that contribute to the same overall problem of poor course placement accuracy or inconsistent standards. Much less common were comprehensive approaches that attended to multiple limitations of the process; these approaches were likely to result from changes to developmental education as a whole. Drawing from the study’s findings, we also discuss how colleges can overcome barriers to reform in order to implement approaches that hold promise for improved course placement accuracy, more consistent standards of college readiness, and, potentially, greater long-term academic success of community college students.
Legislative Barriers to Integrated Practice in Child Advocacy Centres
Creators: name: Jenner, Brianne
Publisher: name: Graduate Studies
Year: 2017

description: A significant portion of the Canadian population has experienced abuse in their childhood, with some studies claiming the prevalence being as high as 32% of Canadians (Afifi et al, 2014). The effects of child abuse-­‐related trauma can be physical and mental and can last well into adulthood. There are also significant fiscal costs associated with child abuse and resultant trauma. The current policy response in Canada is the adoption of Child Advocacy Centres (also known as Child Protection Centres or Youth Advocacy Centres). The Child Advocacy Centre model is based on integration, as agencies occupy the same space and share expertise in order to provide victims with the best possible care and resources. The goal of these centres is to create a “one-­‐stop-­‐shop” of services for victims of abuse. Several cost-­‐benefit analyses of the currently operating centres suggest that they are positive models for streamlining child abuse cases and also have a significant social return on investment. The goal of this study is to illuminate barriers that inhibit integration between organizations within these centres. How and when organizations are permitted to share information are important aspects of such integration. This 6 study analyzed the legislative frameworks that guide these operations and provided recommendations as to how this legislative foundation can be improved. The study looked in more depth at 3 specific Child Advocacy Centres (CACs), their levels of integration, their rules surrounding information-­‐sharing and any barriers beyond legislation that they may encounter. Through the comparative analysis, it was evident that legislation can be a major barrier to integration in CACs. Two recommendations are suggested; First, to create national standards for accrediting CACs in Canada and second, for provinces to provide a legislative foundation that predicates sharing information between experts on the basis of providing the best service provision to victims and not based on the victim's interaction with the justice system.
Groundwater age, life expectancy and transit time distributions in advective-dispersive systems: 1. Generalized reservoir theory

description: We present a methodology for determining reservoir groundwater age and transit time probability distributions in a deterministic manner, considering advective-dispersive transport in steady velocity fields. In a first step, we propose to model the statistical distribution of groundwater age at aquifer scale by means of the classical advection-dispersion equation for a conservative and nonreactive tracer, associated to proper boundary conditions. The evaluated function corresponds to the density of probability of the random variable age, age being defined as the time elapsed since the water particles entered the aquifer. An adjoint backward model is introduced to characterize the life expectancy distribution, life expectancy being the time remaining before leaving the aquifer. By convolution of these two distributions, groundwater transit time distributions, from inlet to outlet, are fully defined for the entire aquifer domain. In a second step, an accurate and efficient method is introduced to simulate the transit time distribution at discharge zones. By applying the reservoir theory to advective-dispersive aquifer systems, we demonstrate that the discharge zone transit time distribution can be evaluated if the internal age probability distribution is known. The reservoir theory also applies to internal life expectancy probabilities yielding the recharge zone life expectancy distribution. Internal groundwater volumes are finally identified with respect to age and transit time. One- and two-dimensional theoretical examples are presented to illustrate the proposed mathematical models, and make inferences on the effect of aquifer structure and macro-dispersion on the distributions of age, life expectancy and transit time.

description: Dynorphin is a potent anti-nociceptive neuropeptide ubiquitously expressed throughout the peripheral and central nervous system. Previous studies have shown that dynorphin is co-packaged and co-released with orexin, a pro-locomotory neuropeptide known to be involved in goal-directed movement. Why then is an inhibitory neuropeptide co-released with an excitatory pro-locomotory neuropeptide orexin, and what is its role? In this thesis, the expression of kappa opioid receptors (KOR) on motoneurons was demonstrated using RNAscope Assay. Consistent with the observation of other studies, my results show that KOR activation significantly reduced spontaneous network activity, increased motoneuron excitability, and increased presynaptic inhibition. These results suggest that dynorphin modulates the spinal motor network rather than inhibits it. This also explains why the co-release of orexin and dynorphin does not have an antagonistic effect. My work suggests that perinatally dynorphin can have potent effects on spinal cord networks. This raises the possibility that dynorphin release may contribute to the development and correct function of spinal cord motor networks.

description: Η παρούσα διπλωματική εργασία επιτελεί διττό σκοπό, ήτοι την παρουσίαση του θεσμού της αστικής ιατρικής ευθύνης των δημοσίων νοσοκομείων, σε περίπτωση τέλεσης ιατρικού σφάλματος από το ιατρικό προσωπικό τους σε βάρος των ασθενών, και την παρουσίαση της σχετικής νομολογίας ως έχει διαμορφωθεί από τα ελληνικά διοικητικά δικαστήρια. To έναυσμα επιλογής του ως άνω θέματος αποτελεί η παραδοχή ότι το ιατρικό σφάλμα τείνει να καταστεί ένα σύνηθες φαινόμενο στην ιατρική πραγματικότητα των δημοσίων νοσοκομείων. Σημαντικές, δε, αιτίες της συχνότητας εμφάνισης του ιατρικού σφάλματος, αποτελούν το φαινόμενο της υπερφόρτωσης (burn- out) των ιατρών, το οποίο αυξήθηκε κατακόρυφα στην διάρκεια της πανδημίας του ιού SARS-CoV-2, σε συνδυασμό με τις ελλείψεις σε ιατρικό εξοπλισμό, σε ιατρικό προσωπικό και οι χαμηλές απολαβές. Ως εκ τούτου, οι Έλληνες ιατροί υπό το καθεστώς ψυχολογικής πίεσης και του φόβου τέλεσης ιατρικών σφαλμάτων, οδηγούνται σιωπηρά στην αμυντική ιατρική. Με την έννοια αυτή, νοείται ότι οι γιατροί καθοδηγούν τους ασθενείς σε αλόγιστες ιατρικές εξετάσεις εκτοξεύοντας το κόστος των εξετάσεων και παρατείνοντας την νοσηλεία των ασθενών επί μακρό χρονικό διάστημα.

description: In order to overcome the problem of decrease of the spraying exhausts purification efficiency caused by the paint mist, the installation combining of the improved sieve-tray tower and the wet electrostatic precipitator (WEP) was used for the treatment of the pilot-scale 1,000 m3 paint waste gas. The characteristics of paint mist were investigated, showing that the size distribution of oil-based paint mist located in the range of 5.4–43.4 μm with an approximate symmetrical distribution under the pressure of 0.4 MPa. The size of paint mist less than 10 μm accounted for ~50% in quantity. It was revealed that the integrated setup was able to remove the concentration of oil-based paint mist with ~98% removal efficiency, in which the improved sieve-tray tower contributed ~94% particles removal. The soluble volatile organic pollutants (VOCs) of spraying exhaust gas were also captured by sieve-tray tower, promoting VOCs removal. At last, the feasibility of integrated setup used in paint mist removal was analyzed, including the secondary pollutants treatment. The results exhibited the setup has the potential for industrial applications. Implications: Fabricating a pilot-scale installation integrated of the improved sieve-tray tower and wet electrostatic precipitator to remove spraying exhaust gas in the furniture factory efficiently. This tech meets China’s VOC emission policy.

description: Most students who enter higher education through a community college fail to earn a postsecondary credential. One reason for this that has not received enough attention is that many students do not enter a college-level program of study. Many new students arrive at community colleges without clear goals for college and careers. Community colleges offer a wide array of programs but typically provide little guidance to help students choose and successfully enter a program of study. Community college departments often do not closely monitor the progress of students who do enter their programs to ensure that they complete. This paper, originally released in April 2011, presents a simple method that community colleges can use to measure rates of program entry and completion using data on students' actual course-taking behaviors rather than declared major or intent. This method is used to track the progress and outcomes of first-time college students over five years using data from an anonymous sample of community colleges. The analysis shows that it is essential for students to enter a program of study as soon as possible. Students who do not enter a program within a year of enrollment are far less likely to ever enter a program and therefore less likely to earn a credential. The paper offers suggestions for ways community colleges can rethink their practices at key stages of students' engagement to substantially increase rates of program entry and completion.

Identifying the Problems of Software Re-architecting and a Knowledge Representation Framework to Address Them
Creators: name: Moazzen, Elham
Publisher: name: Graduate Studies
Year: 2018
Subjects: subject: Computer Science

description: Real-world software undergoes constant change: to fix bugs; to extend functionality; to interact with the changing “ecosystem” around it; and to make internal improvements. Non-trivial software must possess a software architecture: a division into smaller pieces, how those pieces are meant to interact, and how those pieces are deployed physically. As a software architecture can have a significant impact on important properties of the software, the architecture for a software system may need to change as the system itself undergoes change: this is software re-architecting. Unfortunately, software re-architecting is poorly understood: without understanding what is involved in software re-architecting and what problems people encounter in approaching it, we cannot help solve or avoid those problems. I begin this thesis by conducting a case study on a real world example of a software re-architecting, for which documentation and records of discussions were available, to find basic issues that arose during the process. I also conducted a series of interviews with software engineers centred around those issues to deepen our understanding of the process of software re-architecting and discovered the notion of discrete change steps that must be organized and coordinated. I identify a set of critical challenges that must be addressed in any concrete solution. Software engineers lacked a systematic approach to the communication and record management of change steps, suggesting a set of design guidelines for future collaboration tools tailored for re-architecting. They need collaboration tools that facilitate viewing, recording, and retrieving the change steps, and involving the communications within and between the levels of the development team. I then propose a knowledge representation framework for the change process in asynchronous collaboration. This framework is a first step toward a re-architecting collaboration tool that would help to systematize the change process without disrupting it. I developed a paper prototype of the framework and conducted a user evaluation study to determine if the new approach meets the needs of software engineers working on a software re-architecting. My study suggests that the ii approach supported by the prototype allows software engineers to better present changes to their team relative to traditional mechanisms, thereby enabling them to consider more detail. I illustrate the potential value of the framework as a platform for deeper study and further investment in tools, highlighting promising areas for future research.

description: This paper is a literature review that explores the nature and effectiveness of contextualization as a way to improve outcomes for academically underprepared college students. Two forms of contextualization have been studied: "contextualized" and "integrated" instruction. There is more descriptive work on the contextualization of basic skills than studies with student outcome data. In addition, many studies with quantitative evidence on the effectiveness of contextualization have methodological flaws that limit conclusions. Further, only a small number of studies are with college students. However, despite these problems, contextualization seems to be a promising direction for accelerating the progress of academically underprepared college students. The method of contextualization is grounded in a conceptual framework relating to the transfer of skill and student motivation; practitioners who use it observe positive results, and the available quantitative evidence indicates that it has the potential to increase achievement.

description: Artin's conjecture states that supersingular K3 surfaces over finite fields have Picard number 22. In this paper, we prove Artin's conjecture over fields of characteristic p>3. This implies Tate's conjecture for K3 surfaces over finite fields of characteristic p>3. Our results also yield the Tate conjecture for divisors on certain holomorphic symplectic varieties over finite fields, with some restrictions on the characteristic. As a consequence, we prove the Tate conjecture for cycles of codimension 2 on cubic fourfolds over finite fields of characteristic p>3.
