Thermocapillary effects in driven dewetting and self-assembly of pulsed laser-irradiated metallic films

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: In this paper the lubrication-type dynamical model is developed of a molten, pulsed laser-irradiated metallic film. The heat transfer problem that incorporates the absorbed heat from a single beam or interfering beams is solved analytically. Using this temperature field, we derive the 3D long-wave evolution PDE for the film height. To get insights into dynamics of dewetting, we study the 2D version of the evolution equation by means of a linear stability analysis and by numerical simulations. The stabilizing and destabilizing effects of various system parameters, such as the peak laser beam intensity, the film optical thickness, the Biot and Marangoni numbers, etc. are elucidated. It is observed that the film stability is promoted for such parameters variations that increase the heat production in the film. In the numerical simulations the impacts of different irradiation modes are investigated. In particular, we obtain that in the interference heating mode the spatially periodic irradiation results in a spatially periodic film rupture with the same, or nearly equal period. The 2D model qualitatively reproduces the results of the experimental observations of a film stability and spatial ordering of a re-solidified nanostructures.
A Search for Electron Antineutrino Appearance at the $Δm^2 \sim$ 1 $\mathrm{eV}^{2}$ Scale

description: The MiniBooNE Collaboration reports initial results from a search for $\barν_μ\to\barν_e$ oscillations. A signal-blind analysis was performed using a data sample corresponding to $3.39 \times 10^{20}$ protons on target. The data are consistent with background prediction across the full range of neutrino energy reconstructed assuming quasielastic scattering, $200 < E_ν^{QE} < 3000$ MeV: 144 electron-like events have been observed in this energy range, compared to an expectation of $139.2 \pm 17.6$ events. No significant excess of events has been observed, both at low energy, 200-475 MeV, and at high energy, 475-1250 MeV. The data are inconclusive with respect to antineutrino oscillations suggested by data from the Liquid Scintillator Neutrino Detector at Los Alamos National Laboratory.

Form, content, craft and the individual lyric
Creators: name: Jenkins, SD
Publisher: name: University Of Tasmania
Year: 2023

description: This research, conducted through reflective compositional practice, examined and experimented with the lyrical elements of form, content and craft. The project investigated how the songwriter may utilise these elements to fulfil the potential of a song, and examined ways in which the individuality of the lyricist could be enhanced. A key output of this research was a folio of original songs including two albums, The Last Polaroid (2017) and Nylon String Songs (2018). The twenty songs in the folio demonstrate the effective deployment of a range of lyrical elements, including the use of the cognitive length of line, the influential authority of rhyme and rhythm, how sections of variation and repetition organise detail, depth and sonority, how patterns of sound and image intensify sense, and how shapes can inform consequence to allow finer textures to present more immediately. Analysis and critical reflection on poetic and lyrical models from Sappho to Shakespeare to Sondheim that guide the lyrical process are presented in the exegesis, along with a discussion of the key lyrical elements of the songs contained in the folio. The research revealed the deep-seated charm and power of the song form itself, and the potential to harness its adaptability for individual content. The research recognised the appropriate organisation of lyrical elements that then leads to their concealment and enables the engagement and seduction of which songs are capable. This research represents a significant contribution to the literature on techniques of successful songwriting and identifies strategies of relevance to aspiring songwriters.
A shared landscape : Aboriginal and Chinese labour on a New South Wales pastoral station, 1832-1899
Creators: name: Read, Rebecca
Publisher: name: University Of Tasmania
Year: 2023

description: In 1832, William Montagu Rothery and his brother, Frederick, founded Cliefden, a pastoral station in central western New South Wales. This thesis examines Aboriginal and Chinese labour at Cliefden during the period 1832-1899. It takes Cliefden as a case study, a 'situated context' of shared European, Aboriginal and Chinese experience. Using a rich array of archives from this station, it argues that, notwithstanding intense violence on expanding colonial frontiers, some pastoral stations could be places of necessary mutual accommodation and relatively equitable labour. It also argues that, for Chinese, some pastoral stations could be places of ongoing labour outside the goldfields and away from the pernicious anti-Chinese hostility prevalent during the second half of the nineteenth century. In so doing, it aims to add new historical insights into Indigenous and Chinese experience in nineteenth-century rural Australia and reveal the shared landscape of the mid- to late-nineteenth century pastoral station. The daily labour experiences of both Aboriginal and Chinese workers on pastoral stations are areas of developing, but not yet extensive, scholarship. This thesis builds on that scholarship and overturns two general presumptions: that the Aboriginal labour experience on pastoral stations was always based on inequitable labour relations, and that Chinese workers were few, itinerant, and equally underpaid. As well, this thesis offers a more comprehensive view of one pastoral station as a 'contact zone', a 'shared landscape', and a site of colonial labour for Aboriginal, European and Chinese peoples. Historian. Tony Ballantyne recently made the point that, while there is a need for more work that maps broad patterns and pursues large questions, it needs to 'sit alongside and engage with the more specialised and localised research that should be the lifeblood of history as a discipline'. As a localised study, this thesis contributes to that lifeblood
Hybrid Semantics of Stochastic Programs with Dynamic Reconfiguration

description: We begin by reviewing a technique to approximate the dynamics of stochastic programs --written in a stochastic process algebra-- by a hybrid system, suitable to capture a mixed discrete/continuous evolution. In a nutshell, the discrete dynamics is kept stochastic while the continuous evolution is given in terms of ODEs, and the overall technique, therefore, naturally associates a Piecewise Deterministic Markov Process with a stochastic program. The specific contribution in this work consists in an increase of the flexibility of the translation scheme, obtained by allowing a dynamic reconfiguration of the degree of discreteness/continuity of the semantics. We also discuss the relationships of this approach with other hybrid simulation strategies for biochemical systems.

description: Surveillance monitoring is important for detecting variations in species populations in response to natural and anthropogenic environmental changes. For seabirds this typically involves species-specific monitoring at breeding colonies. It is rare that available resources allow all species to be monitored in an area, resulting in gaps in monitoring programs. Here we assess how natural history observations can provide multi-species community-level information on seabird abundance at Macquarie Island. In 2017–2018 we completed 201 land-based surveys of seabirds in inshore waters and a further 137 surveys in 2022–2023. These are compared against a baseline of 391 surveys from 2002–2003. We found that community composition and seasonal variation in relative abundance in the 2017–2018 and 2022–2023 seasons was similar to the baseline surveys, recording 41 of 43 species observed in the baseline. Land-based observations provide evidence of inter-annual variation in diversity and abundance of non-breeding seabirds visiting inshore waters around Macquarie Island, and of increases in breeding petrels responding to invasive species eradication by 2014. Surveys were less reliable for detecting changes in penguin abundance and prions, diving-petrels and storm-petrels. Nocturnal spotlight surveys led to the discovery of the first colonies of Common Diving-petrels on the mainland of Macquarie Island and circumstantial evidence for recolonisation by storm-petrels. The methods documented here provide information relevant to marine spatial planning and management, and for monitoring regional environmental trends. These surveys are a useful supplement to established on-island monitoring.

description: Observations show that magnetic fields in the interstellar medium (ISM) often do not respond to increases in gas density as would be naively expected for a frozen-in field. This may suggest that the magnetic field in the diffuse gas becomes detached from dense clouds as they form. We have investigated this possibility using theoretical estimates, a simple magneto-hydrodynamic model of a flow without mass conservation and numerical simulations of a thermally unstable flow. Our results show that significant magnetic flux can be shed from dense clouds as they form in the diffuse ISM, leaving behind a magnetically dominated diffuse gas.

Accurate position of the X-ray source, determined using Chandra observations, allowed us to associate this source with the faint optical object (m_R=~20.4), which shows broad H_αemission line in its optical spectrum. Therefore we conclude that the source IGRJ18257-0707 is a type 1 Seyfert galaxy at redshift z=0.037.

title: Forced Sex in Battering Relationships: An Ethnographic Investigation
Creators: name: Hofheimer, Leigh
Publisher: name: Old Dominion University Libraries
Year: 1988

description: This research examines the complex problem of forced sex in battering relationships. Interviewing eleven women in a battered women's shelter in a southeastern city, I focused on both their perceptions of forced sex and its effects on their self-esteem, expectations and body-image.

Based on the interviews I conclude that forced sex needs a broader definition than the traditionally accepted definition of rape. In addition, the victims' memories of earlier incidents of physical abuse during sex may influence their perceptions of when they are being forced. This study suggests that future researchers and members of the helping profession should include the victim's perception and incidents of past abuse when trying to understand forced sex or patterns of sexually abusive behaviors in battering relationships.
Regional stream sediment reconnaissance and trace element content of rock, soil and plant material in eastern yukon territory
Creators: name: Doyle, Patrick J.
Publisher: name: University of British Columbia
Year: 2011

description: Multi-element stream sediment reconnaissance in the Hess River region of the Eastern Yukon has outlined an extensive area characterized by anomalously high molybdenum values. An accessible region in the Hess Mountains, within the high molybdenum zone, was selected for detailed study of trace element levels in stream sediment, rock, soil and vegetation. In view of the frequently observed relationship between high forage molybdenum concentrations and the incidence of copper deficiency in cattle, molybdenum concentrations in plant species likely to be consumed by caribou and moose were of particular interest. High sediment molybdenum values are characteristic of catchments underlain by dark shales and less commonly dark limestone. These rocks and associated soils are rich in molybdenum. Concentrations in vegetation growing on anomalous shaly soils are characteristically low, while most plants growing on soils derived predominantly from limestone are molybdenum-rich. The Mo-Cu status of vegetation on limey soils is typically within the range associated with molybdenum induced hypocuprosis in cattle. Low molybdenum uptake by plants on soils derived from shales likely reflects the unavailability of the molybdate anion, resulting from its adsorption onto clay minerals and sesquioxides under acidic conditions prevalent in these soils. In neutral to mildly basic environments, typical of dark limestone soils, molybdenum adsorption is greatly decreased, and therefore molybdenum is relatively available to plants. In the detailed study area soil pH values are typically similar to pH levels in associated stream water. Therefore by combining stream sediment molybdenum concentrations with stream pH data, catchments likely to contain molybdenum-rich vegetation can be predicted. Unfortunately stream pH values were not obtained in the regional survey. In view of the apparent rarity of dark limestone throughout the Eastern Yukon, however, molybdenum-rich vegetation is not likely to be particularily widespread. Wildlife in this area, therefore, is probably not significantly affected by molybdenum induced copper deficiency.

description: Meso- and submesoscales (fronts, eddies, filaments) in surface ocean flow have a crucial influence on marine ecosystems. Their dynamics partly control the foraging behaviour and the displacement of marine top predators (tuna, birds, turtles, and cetaceans). In this work we focus on the role of submesoscale structures in the Mozambique Channel on the distribution of a marine predator, the Great Frigatebird. Using a newly developed dynamical concept, namely the Finite-Size Lyapunov Exponent (FSLE), we have identified Lagrangian coherent structures (LCSs) present in the surface flow in the Channel over a 2-month observation period (August and September 2003). By comparing seabirds' satellite positions with LCSs locations, we demonstrate that frigatebirds track precisely these structures in the Mozambique Channel, providing the first evidence that a top predator is able to track these FSLE ridges to locate food patches. After comparing bird positions during long and short trips, and different parts of these trips, we propose several hypotheses to understand how frigatebirds can follow these LCSs. The birds might use visual and/or olfactory cues and/or atmospheric current changes over the structures to move along these biological corridors. The birds being often associated to tuna schools around foraging areas, a thorough comprehension of their foraging behaviour and movement during the breeding season is crucial not only to seabirds' ecology but also to an appropriate ecosystemic approach of fisheries in the Channel.
On the pre-metric foundations of wave mechanics I: massless waves

Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The mechanics of wave motion in a medium are founded in conservation laws for the physical quantities that the waves carry, combined with the constitutive laws of the medium, and define Lorentzian structures only in degenerate cases of the dispersion laws that follow from the field equations. It is suggested that the transition from wave motion to point motion is best factored into an intermediate step of extended matter motion, which then makes the dimension-codimension duality of waves and trajectories a natural consequence of the bicharacteristic (geodesic) foliation associated with the dispersion law. This process is illustrated in the conventional case of quadratic dispersion, as well as quartic ones, which include the Heisenberg-Euler dispersion law. It is suggested that the contributions to geodesic motion from the non-quadratic nature of a dispersion law might represent another source of quantum fluctuations about classical extremals, in addition to the diffraction effects that are left out by the geometrical optics approximation.

A first cast at a philosophy of fishing
Creators: name: Bossi, Larelle
Publisher: name: University Of Tasmania
Year: 2023

description: There is more to the human activity of fishing than just catching fish. These are not the words of unlucky fishers. It is also not coincidental that this pursuit of the elusive is more than fishing for fish. If fishing did not pose all the challenges of being in pursuit of the elusive, it would not be fishing, nor would it serve as a metaphor for life. And whilst the thesis is inspired by the purest notion of fishing for fish, the existential quest to which the more entails, is inescapable. From Paleolithic Man to a Prioress of a Medieval Nunnery, the human activity of fishing casts its net out to the unknown in search of an elusive creature that smells less like fish and more like the salty-sweet bounty of lost feminine deities. Irrespective of the longstanding use of fishing as an allegory of the spiritual quest (or of human life as such experienced), and the numerous fishing tales that hint at a popular philosophy, one published paragraph from 1880 remains the only Philosophy of Fishing to date. This lacking of philosophical inquiry into fishing has never seemed so queer as in our current conundrum in fisheries management. Management of the last of the hunters and gatherers has proved to be a challenge in fisheries the world over. Beyond the question of twenty first century industrial fishing I argue that the human activity of fishing may play a key role in the understanding of ourselves as a symbolic mind, and moreover, how the activity of fishing itself, as a conduit of two worlds may be an embodied symbol of our humanity. This thesis in three parts aims to demonstrate how a philosophy of fishing may contribute to both the current topological discourse, and its applicability in entering multidisciplinary discussions involving current global issues in fisheries policy and governance. Motivated by Susanne Langer's work on symbolism, and also the fishing tales of celebrated literature, Part I considers how the activity of fishing has been instrumental in understanding ourselves as human beings and further enabling us to connect with that understanding. In Part II, the thinking about a sense of place within the elemental and unframeable waterscape is facilitated through the philosophies of Jose Ortega y Gasset, Jeff Malpas and Freya Mathews. With an aim at synthesizing our evolutionary capacity for symbolism with a topological consideration of an aquatic sense of place, Part III develops an ethical consideration of fishing inspired by the topological philosophies and reflected in the notions of Indigenous kinship and Dreamings they support.

description: For a long time biologists have used visual representations of biochemical networks to gain a quick overview of important structural properties. Recently SBGN, the Systems Biology Graphical Notation, has been developed to standardise the way in which such graphical maps are drawn in order to facilitate the exchange of information. Its qualitative Process Diagrams (SBGN-PD) are based on an implicit Process Flow Abstraction (PFA) that can also be used to construct quantitative representations, which can be used for automated analyses of the system. Here we explicitly describe the PFA that underpins SBGN-PD and define attributes for SBGN-PD glyphs that make it possible to capture the quantitative details of a biochemical reaction network. We implemented SBGNtext2BioPEPA, a tool that demonstrates how such quantitative details can be used to automatically generate working Bio-PEPA code from a textual representation of SBGN-PD that we developed. Bio-PEPA is a process algebra that was designed for implementing quantitative models of concurrent biochemical reaction systems. We use this approach to compute the expected delay between input and output using deterministic and stochastic simulations of the MAPK signal transduction cascade. The scheme developed here is general and can be easily adapted to other output formalisms.
Profitable and unprofitable acres : patterns of European expansion across Van Diemen's Land, 1803-35
Creators: name: Wegman, Imogen
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis uses Historic Geographic Information Systems (HGIS) to uncover the continuing and new patterns of land use in colonial Van Diemen's Land to 1835. In 1817 free settlers were frst encouraged to emigrate to the colony of Van Diemen's Land. They brought with them substantial assets, as well as ideals of British agriculture, and the following years saw a massive transformation of the island's landscape. By the 1820s many visitors assumed these new agriculturalists were aspiring to recreate Britain, and praised what they saw as the early stages of this. They dismissed the work of the former convicts on their much smaller grants, and ignored the thousands of years of land management conducted by the Tasmanian Aboriginal people. In fact, as much as the settlers sought to reshape the landscape, they themselves were reshaped by it. Their aspirations were only possible because of the work of their predecessors. By placing land grants and sales data into an HGIS, this thesis reconstructs the sequence of European settlement in three regions of the island: New Norfolk, Bothwell and through the Midlands. These case studies are used to argue the existence of two primary European settlement patterns. The frst is riverine intensive, a pattern based on European and settler-colonial precedent. The domain of emancipist grantees, the name refects the signifcance of waterways in shaping the early colony. This pattern gave way to the open extensive in the early-1820s, as the colony's economy shifted to fne wool exports and the settlers required larger acreages. This thesis argues that both of these patterns were reliant on the Aboriginal mosaic patterns, as the settlers were drawn to areas kept clear with fre-stick farming. Settlers in the open extensive stage were particularly drawn to the large 'plains', and their land-use represented a drastic departure from accepted British methods. Nonetheless, the riverine intensive settlers also benefted from cleared lands. By combining the settlement pattern parameters with environmental data and settlement sequences, this thesis argues that it is possible to uncover details of the pre-European landscape that were not recorded before it was irrevocably altered by the arrival of large-scale pastoral pursuits. Connecting land records to colonial survey charts also enables this thesis to measure the extent to which acreages were over- or under-measured. Using these fndings, it analyses allegations of corruptions that were frequently levelled against the colonial surveyors. Their work is critiqued within the context of surveyor work-load, changing settler and governmental priorities, and the rise of the Black War.

The scaling of the ZF growth with plasma parameters is examined for typical tokamak parameter values. The physical model used for the toroidal ITG driven mode is based on the ion continuity and ion temperature equations whereas the ZF evolution is described by the vorticity equation. The results indicate that a large ZF growth is found close to marginal stability and for peaked density profiles and these effects may be enhanced by elongation.

description: Nowadays, user authentication is one of the important topics in information security. Text based strong password schemes could provide with certain degree of security. However, the fact that strong passwords being difficult to memorize often leads their owners to write them down on papers or even save them in a computer file. Graphical user authentication (GUA) has been proposed as a possible alternative solution to text based authentication, motivated particularly by the fact that humans can remember images better than text. In recent years, many networks, computer systems and Internet based environments try used GUA technique for their users authentication. All of GUA algorithms have two different aspects which are usability and security. Unfortunately, none of graphical algorithms were being able to cover both of these aspects at the same time. This paper presents a wide range survey on the pure and cued recall based algorithms in GUA, based on ISO standards for usability and attack patterns standards for security. After explain usability ISO standards and attack patterns international standards, we try to collect the major attributes of usability and security in GUA. Finally, try to make comparison tables among all recall based algorithms based on usability attributes and attack patterns those we found.

The influence of wind on the surface waters of Alberni Inlet
Creators: name: Farmer, David Malcolm
Publisher: name: University of British Columbia
Year: 2011

description: Observations of wind, current and surface layer thickness in Alberni Inlet have helped elucidate some of the ways in which the system responds to a surface stress. The energy of the wind and also the current at 2 meters depth is strongly diurnal. Cross-spectral analysis has shown that the two are closely coupled at this frequency. On the basis of simple time scale considerations I have used phase angles between wind and current to estimate a bulk eddy viscosity for the upper two or three meters of the inlet. This method has yielded values between 1 and 10 cm²/sec. On the other hand most of the energy associated with changes in the surface layer thickness is of significantly lower frequency. Strong up-inlet winds induce a sudden thickening in the surface layer at the inlet head and the disturbance appears to propagate back down the inlet suffering an attenuation as it travels. The return to equilibrium can take several days. A simple two-layer frictional model is able to explain much of what is observed and can be used to predict the surface layer thickness on the basis of measured wind speeds.
Australia's legal frameworks for biodiversity conservation : facilitating adaptation in a rapidly changing world
Creators: name: McCormack, Phillipa
Publisher: name: University Of Tasmania
Year: 2023

description: Australia is one of the most biodiverse countries on Earth. However, despite well-established legal frameworks for conservation, its biodiversity is in rapid decline. This national 'biodiversity crisis' will be exacerbated by long-term climate impacts such as sea level rise and species redistribution. Climate change will also compound the impact of existing threats such as invasive species and changing fire regimes. Australian biodiversity must adapt as the climate changes, to avoid increasing rates of species extinction and ecosystem collapse. Despite a growing understanding of the implications of climate change for biodiversity, there has been little consideration of how existing legal frameworks for conservation either facilitate or hinder climate adaptation by species and ecosystems. This thesis addresses this gap, using the adaptation strategies most commonly advocated in conservation scholarship as a lens to investigate Australian conservation laws and policies for facilitating climate adaptation. The adaptation strategies are: (1) increasing and enhancing the protected area estate; (2) improving landscape connectivity; (3) reducing non-climatic stressors; (4) translocating organisms at risk of extinction; and (5) engaging proactively with ex situ conservation. This analysis shows that while each adaptation strategy is present in Australia's law and policy, none are designed to respond to climate change or facilitate climate adaptation. This analysis also finds that conservation paradigms underpinning existing laws contribute to the lack of targeted adaptation laws. These paradigms embed a static concept of 'nature' and emphasise the value of 'wild' nature removed from human influence. Implementation of each adaptation strategy demonstrates additional limitations, including a lack of clarity about desirable conservation outcomes for biodiversity and a consistent failure to adequately legislate, implement or achieve adaptive management processes and outcomes. This thesis proposes three principles to guide legal reform. Conservation laws must embody proactive conservation approaches, improve legal flexibility without reducing accountability, and prioritise adaptive management for biodiversity conservation. This novel approach provides practical insights for improving the way adaptation strategies are implemented in Australia, with lessons for countries facing similar conservation challenges under climate change.

description: To study the evolution of high mass cores, we have searched for evidence of collapse motions in a large sample of starless cores in the Orion molecular cloud. We used the Caltech Submillimeter Observatory telescope to obtain spectra of the optically thin (\H13CO+) and optically thick (\HCO+) high density tracer molecules in 27 cores with masses $>$ 1 \Ms. The red- and blue-asymmetries seen in the line profiles of the optically thick line with respect to the optically thin line indicate that 2/3 of these cores are not static. We detect evidence for infall (inward motions) in 9 cores and outward motions for 10 cores, suggesting a dichotomy in the kinematic state of the non-static cores in this sample. Our results provide an important observational constraint on the fraction of collapsing (inward motions) versus non-collapsing (re-expanding) cores for comparison with model simulations.

We also prove that locally approximately inner and uniformly outer Z^2-actions on a unital simple AF algebra with a unique trace have the Rohlin property and classify them up to cocycle conjugacy employing the OrderExt group as classification invariants.

description: A general method for proving continuity of the von Neumann entropy on subsets of positive trace-class operators is considered. This makes it possible to re-derive the known conditions for continuity of the entropy in more general forms and to obtain several new conditions. The method is based on a particular approximation of the von Neumann entropy by an increasing sequence of concave continuous unitary invariant functions defined using decompositions into finite rank operators. The existence of this approximation is a corollary of a general property of the set of quantum states as a convex topological space called the strong stability property. This is considered in the first part of the paper.

This insight indicate that the Lorentz-Force-like equation has a fundamental meaning in physics. We show how this result may be spinorially obtained starting out out from the application of an infinitesimal element of SL(2,C) to the individual spinors, which are regarded here as being more fundamental objects than four-vectors. In this way we get a set of new dynamical spinor equations inducing the extended Lorentz-Force-like equation in the Minkowski space-time and geometrically obtain the spinor form of the electromagnetic field tensor. The term extended refers to the dynamics of some additional degrees of freedom that may be associated with the intrinsic spin, namely, with the dynamics of three spacelike mutually orthogonal four-vectors, all of them orthogonal to the linear four-momentum of the object under consideration that finally, in the particle's proper frame. are identified with the generators of SU(2).

description: Το νέο αναλυτικό πρόγραμμα σπουδών για τα Αγγλικά στο Λύκειο εκπονήθηκε από το ΙΕΠ και εφαρμόστηκε πιλοτικά το έτος 2021-2022. Στην παρούσα διπλωματική εργασία διερευνήθηκαν οι απόψεις των εκπαιδευτικών που το υλοποίησαν μέσω ημιδομημένων συνεντεύξεων και ποιοτικής ανάλυσης των δεδομένων που συλλέχθηκαν. Ο σκοπός ήταν η καταγραφή της δυναμικής του νέου προγράμματος και η έκθεση των αδυναμιών του. Κατά την έρευνα, οι επιλεγμένοι εκπαιδευτικοί που το υλοποίησαν σε πρότυπα και πειραματικά Λύκεια αρχικά απέδωσαν μία λεπτομερή περιγραφή του προγράμματος όπως το εξέλαβαν στην πράξη. Ακολούθως, τοποθετήθηκαν σε επιμέρους άξονες όπως η στοχοθεσία, τα θετικά στοιχεία που αποκόμισαν και οι δυσκολίες που αντιμετώπισαν. Εν κατακλείδι, υπέβαλαν τις προτάσεις τους για την βελτίωσή του και αποτελεσματικότερη εφαρμογή του σε ευρύτερη κλίμακα. Συμπερασματικά, το νέο πρόγραμμα σπουδών αποδεικνύεται ένα χρήσιμο και αποδοτικό εργαλείο στην φαρέτρα των εκπαιδευτικών κυρίως γιατί είναι ιδιαίτερα ελκυστικό για τους μαθητές και προσαρμοσμένο στις εκπαιδευτικές τους ανάγκες.

description: The quantum corrections to the energies of the $Γ$ point optical phonon modes (Kohn anomalies) in graphene nanoribbons are investigated. We show theoretically that the longitudinal optical modes undergo a Kohn anomaly effect, while the transverse optical modes do not. In relation to Raman spectroscopy, we show that the longitudinal modes are not Raman active near the zigzag edge, while the transverse optical modes are not Raman active near the armchair edge. These results are useful for identifying the orientation of the edge of graphene nanoribbons by G band Raman spectroscopy, as is demonstrated experimentally. The differences in the Kohn anomalies for nanoribbons and for metallic single wall nanotubes are pointed out, and our results are explained in terms of pseudospin effects.

description: _Barefoot_ is Kevin Hart's eighth collection of poems; it is rich in elegies, meditations on lost love, and celebrations of new love. The title speaks of mourning, pilgrimage, and the direct sensuous contact of flesh with earth. Harold Bloom has long extolled Hart as a 'visionary of desire,' and in this collection we find that vision deepened and that desire extended. Never before has Hart stretched his range of inspiration quite so far; while continuing to draw from Christianity, he also responds to the rich heritage of American Blues, and reveals a wit as sharp as a razor's edge. The poetry is at once religious poetry and love poetry; indeed, the 'religious poetry' is itself love poetry. Always, Hart speaks to us in words that seem inevitable in their simplicity. As he himself has written, 'The best conductor of mystery is clarity. The true bearer of complexity is simplicity.' Barefoot will delight poetry lovers everywhere.

On the compact HII galaxy UM 408 as seen by GMOS-IFU: Physical conditions

description: We present Integral Field Unit GMOS-IFU data of the compact HII galaxy UM408, obtained at Gemini South telescope, in order to derive the spatial distribution of emission lines and line ratios, kinematics, plasma parameters, and oxygen abundances as well the integrated properties over an area of 3"x4".4(~750x1100 pc) located in the central part of the galaxy. The starburst in this area is resolved into two giant regions of ~375 and 250pc diameter, respectively. The ages of these two regions, estimated using Hb equivalent widths, suggest that they are coeval events of ~5Myr with stellar masses of ~10^4M_o. We have also used [OIII]/Hb and [SII]/Ha ratio maps to explore the excitation mechanisms in this galaxy. The Ha emission line was used to measure the radial velocity and velocity dispersion. We derived an integrated oxygen abundance of 12+log(O/H)=7.87 summing over all spaxels in our field of view. An average value of 12+log(O/H)=7.77 and a difference of D(O/H)=0.47 between the minimum and maximum values (7.58+-0.06-8.05+-0.04) were found, considering all data points where the oxygen abundance was measured. The spatial distribution of oxygen abundance does not show any significant gradient across the galaxy. On the other hand, the bulk of data points are lying in a region of +-2sigma dispersion (with sigma=0.1 dex) around the average value, confirming that this compact HII galaxy as other previously studied dwarf irregular galaxies is chemically homogeneous. Therefore, the new metals processed and injected by the current star formation episode are possibly not observed and reside in the hot gas phase, whereas the metals from previous events are well mixed and homogeneously distributed through the whole extent of the galaxy.

Νέα Δημόσια Διοίκηση
Διοίκηση ολικής ποιότητας
Κοινό πλαίσιο αξιολόγησης

description: Η παρούσα εργασία ασχολείται με την εφαρμογή της διοίκησης μέσω στόχων στο δημόσιο τομέα. Ξεκινώντας με τη μετάβαση από την έννοια της δημόσιας διοίκησης στην έννοια της δημόσιας διαχείρισης, εξετάζεται η ‘Νέα Δημόσια Διοίκηση’, οι μεταρρυθμίσεις που αυτή εισήγαγε, καθώς και οι λόγοι για τους οποίους αναπτύχθηκε και επικράτησε στη λειτουργία των δημοσίων οργανισμών σε διάφορες χώρες του κόσμου. Διερευνάται, εξάλλου, η Διοίκηση Ολικής Ποιότητας ως μια καινοτόμος μορφή οργάνωσης και το Κοινό Πλαίσιο Αξιολόγησης ως εργαλείο αυτοαξιολόγησης της απόδοσης ενός οργανισμού, η χρήση του οποίου οδηγεί στην καθιέρωση ενός ολοκληρωμένου κύκλου ποιότητας σε αυτόν. Στο δεύτερο κεφάλαιο της εργασίας αναπτύσσονται οι έννοιες της στρατηγικής διοίκησης και διαχείρισης, το ζήτημα της εφαρμογής του Κοινού Πλαισίου Αξιολόγησης στον ελληνικό δημόσιο τομέα και του εκσυγχρονισμού του, λαμβάνοντας υπόψη την αποτίμηση και αξιολόγηση της απόδοσης ως αποτέλεσμα της η Διαχείρισης Βάσει Στόχων. Αναλύεται ο βαθμός υιοθέτησής της στις δημόσιες υπηρεσίες της χώρας και αναδεικνύονται τα πλεονεκτήματα και μειονεκτήματα που προκύπτουν κατά την υλοποίησή της. Ακολούθως αναλύεται το εθνικό θεσμικό πλαίσιο της διοίκησης βάσει στόχων στο δημόσιο τομέα και οι αλλαγές που έχουν επέλθει σε αυτό μετά την έκδοση του ν. 3230/2004 ο οποίος καθιέρωσε το σύστημα Διοίκησης μέσω Στόχων και τη μέτρηση της αποδοτικότητας στην ελληνική Δημόσια Διοίκηση, με όρους στρατηγικής διοίκησης. Τέλος επιλέγεται ως μελέτη περίπτωσης η στοχοθεσία του Υπουργείου Αγροτικής Ανάπτυξης και Τροφίμων με αναφορές στοιχείων από το έτος 2018 αλλά και σήμερα. Εξάγονται συμπεράσματα σχετικά με τον τρόπο υλοποίησής της τα τελευταία έτη και διατυπώνονται προτάσεις για βελτίωση και αύξηση της αποτελεσματικότητάς της.
