description: What is the luminosity needed for discovering new physics if the electroweak scale is to remain stable? In this work we study this question, with the example of a real singlet scalar which couples to the Higgs field already at the renormalizable level. Observing that the electroweak scale remains stable if the two scalars couple in a seesawic fashion, we show that the HL-LHC, expected to deliver an integrated luminosity around 3/ab, can discover scalars weighing up to 800 GeV. The FCC-hh, on the other hand, can discover scalars as heavy as 2.3 TeV at 100/ab luminosity. It thus follows that the new physics that does not destabilize the electroweak scale can be accessed only at high luminosities, and is not possible exclude by the current LHC results.

description: The present study examined the relationship between waste distribution and camera surveillance. We hypothesized that notifying individuals of a presence of a surveillance camera will increase sorting accuracy. Additionally, we hypothesized that reminding participants of the presence of surveillance in a more threatening tone will have a higher effect on sorting accuracy than reminders which follow a more neutral tone. Disposal bins were monitored for 4 weeks with each week consisting of a different poster notifying individuals of a camera surveying the disposal bins. Our findings did not support our hypothesis as camera surveillance did not improve sorting accuracy and there was no significant difference in sorting accuracy based on the tone of the posters.

description: We report on observations of the blazar W Comae (ON+231) with the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE), a wavefront-sampling atmospheric Cherenkov telescope, in the spring of 2003. In a data set comprising 10.5 hours of ON-source observing time, we detect no significant emission from W Comae. We discuss the implications of our results in the context of the composition of the relativistic jet in W Comae, examining both leptonic and hadronic models for the jet. We derive 95% confidence level upper limits on the flux at the level of 1.5--3.5 x 10^{-10} cm^{-2} s^{-1} above 100 GeV for the leptonic models, or 0.5--1.1 x 10^{-10} cm^{-2} s^{-1} above 150 GeV for the hadronic models.

A Compliance-Based Framework for Digital Identity Management in Organizations

Publisher: name: RMIT University
Year: 2025
Subjects: classificationCode: 360202
subject: Digital writing

description: Digital identities are the digital representation of identifiable information of individuals stored in computerised information systems in organizations. They are becoming increasingly important due to the rapid development of information and communication technologies and the potential misuse of such critical information with profound consequences such as increased business loss, damaged organizational credibility and customer trust, reduced revenue, and decreased share price. As a result, managing the digital identity of individuals is critical for minimising the potential loss from digital identity theft in organizations. How digital identity can be managed more effectively, however, remains to be better addressed.

This study aims to investigate how organizations can better manage the digital identity of individuals in organizations. Specifically, it aims to (a) identity the critical factors for the adoption of a compliance-based approach to managing digital identities and (b) develop a compliance-based framework for better managing digital identities in organizations. A quantitative research methodology is adopted to fulfill the aims of this research. A theoretical framework is developed by hypothesizing the critical factors affecting the adoption of compliance-based approaches in managing digital identities in organizations. With the use of survey data collected from full-time employees in Australia, the theoretical framework is tested and validated using structural equation modelling.

The study shows that there is a significant impact of sanction certainty on the attitude of employees towards complying with digital identity management policies and standards. It reveals that attitude, subjective norms, and self-efficacy positively influence the continued intention of employees in complying to organizational standards and policies in managing digital identities. Based on the critical factors identified, a revised framework for better understanding the adoption of the compliance-based approach in managing digital identities in Australia is developed.

This study provides both theoretical and practical contributions. From a theoretical perspective, this study develops a validated research model for better understanding the adoption of a compliance-based approach for managing digital identities in organizations. From a practical perspective, this research offers organizations with insightful findings to aid in the development of tailored strategies and policies for better managing digital identities.

description: Recently, ``Higgsless'' models of electroweak symmetry breaking have been proposed. Based on compactified five-dimensional gauge theories, these models achieve unitarity of electroweak boson self-interactions through the exchange of a tower of massive vector bosons rather than the exchange of a scalar Higgs boson. In this paper, using deconstruction, we analyze the form of the corrections to the electroweak interactions in a large class of these models, allowing for arbitrary 5-D geometry, position-dependent gauge coupling, and brane kinetic energy terms. We show that many models considered in the literature, including those most likely to be phenomenologically viable, are in this class. By analyzing the asymptotic behavior of the correlation function of gauge currents at high momentum, we extract the exact form of the relevant correlation functions at tree-level and compute the corrections to precision electroweak observables in terms of the spectrum of heavy vector bosons. We determine when nonoblique corrections due to the interactions of fermions with the heavy vector bosons become important, and specify the form such interactions can take. In particular we find that in this class of models, so long as the theory remains unitary, S-4 c^2__W T > O(1), where S and T are the usual oblique parameters. We concur with the result of Cacciapaglia et.al. that small or negative S is possible -- though only at the expense of substantial negative T at tree-level. Although we stress our results as they apply to continuum 5-D models, they apply also to models of extended electroweak gauge symmetries motivated by models of hidden local symmetry.

Based on the Principles of Circular Economy with a Perspective of Sustainable Livestock Farming" addresses the environmental issue caused by organic waste in the meat industry. The study highlights the importance of livestock farming in meat production in Colombia, where the sector has grown significantly, generating 886,000 tons in 2018. However, said growth, has increased the environmental impact, especially due to waste generation such as manure and organic sludge. Frigorífico Guadalupe S.A.S., located in Bogotá, produces between 350 and 400 tons of organic waste monthly, which is transported to distant composting plants, raising costs and carbon footprint. The objective of this research is to explore sustainable strategies to manage this waste locally, promoting circular economy and sustainable livestock practices. Ultimately, it seeks the improvement of growth and sustainability strategies of Frigorífico Guadalupe S.A.S., aligning with the Sustainable Development Goals, particularly those related to sustainable cities and responsible production and consumption

description: We present a numerical study of spatially quasi-periodic traveling waves on the surface of an ideal fluid of infinite depth. This is a generalization of the classic Wilton ripple problem to the case when the ratio of wave numbers satisfying the dispersion relation is irrational. We propose a conformal mapping formulation of the water wave equations that employs a quasi-periodic variant of the Hilbert transform to compute the normal velocity of the fluid from its velocity potential on the free surface. We develop a Fourier pseudo-spectral discretization of the traveling water wave equations in which one-dimensional quasi-periodic functions are represented by two-dimensional periodic functions on the torus. This leads to an overdetermined nonlinear least squares problem that we solve using a variant of the Levenberg-Marquardt method. We investigate various properties of quasi-periodic traveling waves, including Fourier resonances, time evolution in conformal space on the torus, asymmetric wave crests, capillary wave patterns that change from one gravity wave trough to the next without repeating, and the dependence of wave speed and surface tension on the amplitude parameters that describe a two-parameter family of waves.

INTEGRAL Spectroscopy of IRAS 17208-0014: Implications for the Evolutionary Scenarios of Ultraluminous Infrared Galaxies

description: New integral field optical fiber spectroscopy obtained with the INTEGRAL system, together with archival {\it {\it HST}} WFPC2 and NICMOS images, have been used to investigate the ultraluminous infrared galaxy IRAS 17208$-$0014, one of the coldest and most luminous objects in the IRAS 1 Jy sample. The 2D gas velocity field identifies the {\it optically faint} K-band nucleus as the {\it true} dynamical nucleus of the galaxy, and shows that the 3 kpc, tilted (i $\sim$ 35 degree) disk is rotating at $Δ$Vsin$i$= 250 km s$^{-1}$. The kinematical, morphological and photometric evidence presented here supports the idea that in IRAS 17208-0014 we are witnessing a luminous, cool ULIRG which is at the final coalescence phase of a system composed of two spirals with m $\leq$ m$^*$, a mass ratio of 2:1, each consisting of a disk+bulge internal structure, that have been involved in a prograde encounter. This system will most likely evolve into an intermediate-mass ($\sim$ L$^*$) elliptical. The multifrequency empirical evidence gathered so far shows no trace of a luminous QSO, and indicates that starbursts dominate the energy output in this galaxy. Therefore IRAS 17208$-$0014 questions the universality of the ULIRG to QSO evolutionary scenario proposed by Sanders and collaborators, and supports the one recently proposed by Colina et al, where two low mass disk galaxies would produce luminous cool ULIRGs that would not evolve into a QSO phase.

description: High speed photometry of the new AM CVn star in Hya (previously known as SN2003aw), spectroscopically identified by Chornock & Filippenko, shows it to have a superhump period of 2041.5 +/- 0.3 s. We find a range of brightness from V ~ 16.5 to 20.3, presumably caused by variations in the rate of mass transfer. In the intermediate state the system cycles in brightness with a period of ~ 16 h and range >= 0.4 mag. There are sidebands to the principal frequencies in the Fourier transform which have constant frequency difference from the superhump harmonics.

description: We consider the problem of recovering a complex vector $\mathbf{x}\in \mathbb{C}^n$ from $m$ quadratic measurements $\{\langle A_i\mathbf{x}, \mathbf{x}\rangle\}_{i=1}^m$. This problem, known as quadratic feasibility, encompasses the well known phase retrieval problem and has applications in a wide range of important areas including power system state estimation and x-ray crystallography. In general, not only is the the quadratic feasibility problem NP-hard to solve, but it may in fact be unidentifiable. In this paper, we establish conditions under which this problem becomes {identifiable}, and further prove isometry properties in the case when the matrices $\{A_i\}_{i=1}^m$ are Hermitian matrices sampled from a complex Gaussian distribution. Moreover, we explore a nonconvex {optimization} formulation of this problem, and establish salient features of the associated optimization landscape that enables gradient algorithms with an arbitrary initialization to converge to a \emph{globally optimal} point with a high probability. Our results also reveal sample complexity requirements for successfully identifying a feasible solution in these contexts.

description: Glioblastoma is a highly aggressive glioma with limited treatment options. Boron neutron capture therapy (BNCT) offers a promising approach for refractory cancers, utilizing boron-10 (10B) and thermal neutrons to generate cytotoxic particles. Effective BNCT depends on selective targeting and retention of 10B in tumors. Current BNCT drugs face issues with rapid clearance and poor tumor accumulation. To address this, we developed gold nanoparticles (AuNPs) functionalized with cyclic arginine-glycine-aspartic acid (cRGD) peptides as a nanocarrier for Sodium Mercaptododecaborate (BSH), resulting in AuNPs-BSH&PEG-cRGD. In vitro, AuNPs-BSH&PEG-cRGD increased 10B content in GL261 glioma cells by approximately 2.5-fold compared to unmodified AuNPs-BSH&PEG, indicating enhanced targeting due to cRGD's affinity for integrin receptor αvβ3. In a subcutaneous glioma mouse model, 6 h post-intratumoral administration, the 10B concentration in tumors was 17.98 μg/g for AuNPs-BSH&PEG-cRGD, significantly higher than 0.45 μg/g for BSH. The tumor-to-blood (T/B) and tumor-to-normal tissue (T/N) ratios were also higher for AuNPs-BSH&PEG-cRGD, suggesting improved targeting and retention. This indicates that AuNPs-BSH&PEG-cRGD may enhance BNCT efficacy and minimize normal tissue toxicity. In summary, this study provides a novel strategy for BSH delivery and may broaden the design vision of BNCT nano-boron capture agents.

description: In 5 dimensions the electroweak symmetry can be broken by boundary conditions, leading to a new type of Higgsless theories. These could in principle improve on the 4D case by extending the perturbative domain to energies higher than $4 πv$ and by allowing a better fit to the electroweak precision tests. Nevertheless, it is unlikely that both these improvements can be achieved, as we show by discussing these problems in an explicit model.

description: Understanding drug behavior within the skin, especially for photosensitive compounds, is crucial for developing effective and safe topical therapies. This study employs Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging (MALDI-MSI) and Liquid Chromatography-Mass Spectrometry (LC-MS/MS) to investigate the skin permeation and photostability of selumetinib, a MEK inhibitor used in treating type 1 neurofibromatosis (NF1). The highest amounts of selumetinib in the skin sections were obtained when using the gel formulation, suggesting that it is to be preferred to cream formulations to achieve higher permeation of the drug. Our study also revealed that selumetinib is amenable to photodegradation in ex vivo skin explants, and yields one main degradation product, whose degradation is likely triggered by hydrogen abstraction. MALDI-MSI results showed selumetinib and its degradation product concentrate in skin appendages, indicating these structures might serve as drug reservoirs, potentially prolonging retention and efficacy. This study demonstrates that combining MALDI-MSI with LC/MS-MS can highly contribute to the characterization of the fate of photosensitive compounds in the skin, an essential prerequisite to the development of compound-specific photoprotective measures. It will also pave the way for innovative topical delivery strategies for NF1 treatment.

description: Nanostructured La0.67Ca0.33MnO3 (NS-LCMO) was formed by pulsed-laser deposition on the surface of porous Al2O3. The resistance peak temperature (Tp) of the NS-LCMO increases with increasing average thickness of the films, while their Curie temperatures (Tc) remain unchanged. The coercive field of the samples increases with decreasing film thickness and its temperature dependence can be well described by Hc(T) = Hc(0)[1-(T/TB)1/2]. A large magnetoresistance and strong memory effect were observed for the NS-LCMO. The results are discussed in terms of the size effect, Coulomb blockade and magnetic tunneling effect. This work also demonstrates a new way to get nanostructured manganites.

description: Contaminated compost bins are a huge obstacle in the goal when striving for a greener environment. For our research question, we asked “How can informative, eye-catching posters influence the number of contaminants in compost bins?” We hypothesized that residents are significantly more likely to compost without contaminants (i.e plastic bags) when composting in a building with posters promoting correct composting behaviours compared to a building without posters. Our study was conducted on the residents of the Ponderosa Cedar and Oak House residences. To test our hypothesis, we posted a number of posters that promote proper composting techniques and raised awareness of plastic contamination in the compost bins in the compost room of the Cedar House while leaving the Oak House compost room free of intervention. Over the course of two weeks, we collected data from the Ponderosa Cedar and Oak House residences and found that our intervention had no statistically significant effect on the proper composting rates.

description: The hard X-ray sensitivity and arcminute position accuracy of the recently launched International Gamma-Ray Laboratory (INTEGRAL) has lead to the (re-)discovery of a class of heavily absorbed hard X-ray sources lying in the Galactic plane. We report on the analysis of an XMM observation of such a source IGR J16320-4751 = AX J1631.9-4752. Our analysis allowed us to obtain the most accurate X-ray position to date (Rodriguez et al. 2003), and to identify a likely infrared counterpart (Tomsick et al. 2003). We present the detailed analysis of the IGR J1632-4751 XMM spectra. The PN spectrum can be well represented by a single powerlaw or a comptonized spectrum with a high equivalent absorption column density of ~ 2 x10^{23} cm^{-2}. The current analysis and the comparison with the properties of other sources favor the possibility that the source is a Galactic X-Ray Binary (XRB). The identification of two candidate IR counterparts is in good agreement with this identification. The hard spectrum previously seen with ASCA, and the brightness of the candidate counterparts indicate that IGR J1632-4751 is most probably a highly absorbed High Mass X-ray Binary, hosting a neutron star.

description: While linagliptin is the most potent dipeptidyl peptidase 4 inhibitor, its use is limited due to poor bioavailability and the potential risk of pancreatic injury. Here, we investigated whether the sustained weekly administration of linagliptin could provide better effect compared to frequent daily oral administration. Type 2 diabetes was induced by feeding rats a high fructose/fat/salt diet followed by STZ injection. Compared to the partial glycemic control achieved with daily oral linagliptin, a weekly subcutaneous injection containing about one-fourth of the oral dose produced superior glycemic control, as evidenced by the 4-week postprandial glucose follow-up and oral glucose tolerance test. This was confirmed by the significant increase in serum insulin in the case of the sustained linagliptin administration. Higher levels of the anti-inflammatory cytokine adiponectin and lower triglyceride levels were observed after sustained linagliptin administration compared with daily oral linagliptin. In addition, sustained linagliptin displayed a significant increase in β-cells’ insulin immunoreactivity when compared with daily linagliptin. More reduction in collagen deposition and caspase-3 immunoreactivity in pancreatic tissue were observed in sustained linagliptin compared with oral linagliptin. In conclusion, sustained linagliptin administration provided superior glycemic control, which seems to be mediated by more reduction in pancreatic injury.

description: We study the spinorial Killing equation of supergravity involving a torsion 3-form $\T$ as well as a flux 4-form $\F$. In dimension seven, we construct explicit families of compact solutions out of 3-Sasakian geometries, nearly parallel $\G_2$-geometries and on the homogeneous Aloff-Wallach space. The constraint $\F \cdot Ψ= 0$ defines a non empty subfamily of solutions. We investigate the constraint $\T \cdot Ψ= 0$, too, and show that it singles out a very special choice of numerical parameters in the Killing equation, which can also be justified geometrically.

description: The general theme of this note is illustrated by the following theorem: Theorem 1. Suppose $K$ is a compact set in the complex plane and 0 belongs to the boundary $\partial K$. Let ${\cal A}(K)$ denote the space of all functions $f$ on $K$ such that $f$ is holomorphic in a neighborhood of $K$ and $f(0)=0$. Also for any given positive integer $m$, let ${\cal A}(m,K)$ denote the space of all $f$ such that $f$ is holomorphic in a neighborhood of $K$ and $f(0)=f^{\prime}(0)=...=f^{(m)}(0)=0$. Then ${\cal A}(m,K)$ is dense in ${\cal A}(K)$ under the supremum norm on $K$ provided that there exists a sector $W=\{r\hbox{\rm e}^{iθ}; 0\leq r\leqδ,α\leqθ\leqβ\}$ such that $W\cap K=\{0\}$. (This is the well-known Poincare's external cone condition). We present various generalizations of this result in the context of higher dimensions replacing holomorphic with harmonic.

title: A General Ecology of Bryozoans at Signy Island, Antarctica
Creators: name: Barnes, David Keith Alan
Publisher: name: The Open University
Year: 1995

description: This study set out to investigate a broad range of ecological aspects in Antarctic bryozoans, including distribution, feeding, growth and predation, and how these were influenced by environmental conditions. A number of sites, at a variety of depths, were chosen from within Borge Bay, Signy Island in the South Orkneys, using SCUBA. Some of these studies atempted to monitor populations in situ over tlie course of two years, mainly with the aid of underwater cameras.

Photographic samples were taken on three vertical transects of 5.5 m rock faces and two 40 m sloping transects. The percentage cover of substratum ranged from 0-100% and the colonising communities included representitives of 10 phyla. Ice impact, depth and profile were important influences on community cover and composition. Collections of up to 200 rocks were made from each of six localities ranging from the intertidal to 42 m. Area colonised, number of colonising phyla, bryozoan species and colonies were all found to increase with substratum surface area and depth. Over 4000 competitive interactions between bryozoans were recorded, which indicated the presence of a competitive hierarchy with one ultimately dominant species. Colonisation of artificial substrata was very slow comparative to that found by similar temperate studies and suggested an essentially classical successional pattern of colonisation. Bryozoans were abundant on the externa of a variety of other macroinveitebrates, including fouling the surfaces of erect bryozoan species.

Lophophore activity (feeding) occurred for most of the year in the bryozoans monitored, and environmental cues were suggested for the changes in activity of some species. Growth was generally slow but contrasted strongly in duration between the monitored species. The growth checks, formed annually by one species, showed interannual variations in growtli throughout the population. Two bryozoan species had specific nudibranch predators, though their populations seemed little influenced by predation.

description: We report a unique feature of magnetic field Feshbach resonances in which atoms collide with non-zero orbital angular momentum. P-wave ($l=1$) Feshbach resonances are split into two components depending on the magnitude of the resonant state's projection of orbital angular momentum onto the field axis. This splitting is due to the magnetic dipole-dipole interaction between the atoms and it offers a means to tune anisotropic interactions of an ultra-cold gas of atoms. A parameterization of the resonance in terms of an effective range expansion is given.
Μελέτη του κλάδου της φαρμακοβιομηχανίας στην Ελλάδα και η συμβολή του στην ελληνική οικονομία

subject: Ελληνική οικονομία

description: Η φαρμακευτική βιομηχανία είναι ένας σημαντικός κλάδος των συστημάτων υγειονομικής περίθαλψης σε όλο τον κόσμο, καθώς είναι υπεύθυνη για την έρευνα, ανάπτυξη, παραγωγή και διανομή φαρμάκων. Στηρίζεται κυρίως στην επιστημονική έρευνα και ανάπτυξη (Ε&Α) σκευασμάτων που προλαμβάνουν ή θεραπεύουν ασθένειες και διαταραχές. Η παραγωγή φαρμακευτικών προϊόντων στην Ελλάδα εκτιμήθηκε στα 948 εκατομμύρια ευρώ, με την ακαθάριστη προστιθέμενη αξία (εκ του εργοστασίου) στα 624 εκατομμύρια ευρώ, δηλαδή σε 3,4% της μεταποίησης, το 2016, ενώ το 2018 έφτασε το 1 δισεκατομμύριο ευρώ, με προστιθέμενη αξία στα 559 εκατομμύρια ευρώ, αντιπροσωπεύοντας το 3% του συνολικού μεταποιητικού τομέα. Κατατάσσεται στην 9η θέση μεταξύ 24 άλλων μεταποιητικών τομέων σε εθνικό επίπεδο. Ο σκοπός της παρούσας εργασίας είναι να αναλύσει και να καταγράψει τη γενικότερη πορεία της φαρμακευτικής βιομηχανίας στην Ελλάδα και της σημαντικότητάς της για την ελληνική οικονομία. Για την παρούσα μελέτη αξιοποιήθηκε η ποιοτική ερευνητική προσέγγιση της ανάλυσης εγγράφων, καθώς αναλύθηκαν τα στοιχεία από τις επίσημες, ετήσιες εκθέσεις του Ιδρύματος Οικονομικών και Βιομηχανικών Ερευνών (ΙΟΒΕ), οι οποίες εκπονήθηκαν, σε συνεργασία με το Σύνδεσμο Φαρμακευτικών Επιχειρήσεων Ελλάδος (ΣΦΕΕ). Μέσα από τις μελέτες αυτές παρατέθηκαν τα στοιχεία της αγοράς για τα έτη 2007 έως 2020, ενώ η συστηματική ανάλυση που πραγματοποιήθηκε επικεντρώνεται περισσότερο στην πρόσφατη πενταετία 2015-2019. Από τις αναλύσεις των στοιχείων προέκυψε ότι αν και ο φαρμακευτικός κλάδος υπέστη σημαντικές ζημίες λόγω των συνεχών μεταρρυθμίσεων από το 2010 και έπειτα, υπήρξε σημαντικός κινητήριος μοχλός για την ελληνική οικονομία, παρουσιάζοντας υψηλότερα επίπεδα ανθεκτικότητας σε σύγκριση με άλλους τομείς του μεταποιητικού κλάδου. Επίσης, ο κλάδος βασίζεται τα τελευταία χρόνια σε πολύ μεγάλο βαθμό στις εξαγωγές, στις επενδύσεις σε έρευνα και ανάπτυξη και στο υψηλά καταρτισμένο ανθρώπινο δυναμικό με υψηλό εκπαιδευτικό και ακαδημαϊκό υπόβαθρο.

description: Η παρούσα εργασία ασχολείται με τη βιώσιμη ηγεσία στη δευτεροβάθμια εκπαίδευση. Αρχικά, στην εργασία γίνεται αναφορά στην έννοια της βιώσιμης ανάπτυξης και στους στόχους της βιώσιμης ανάπτυξης, ενώ ακολουθεί αναφορά στη σχέση μεταξύ βιώσιμης ανάπτυξης και εκπαίδευσης. Στη συνέχεια, η εργασία επικεντρώνεται στην έννοια της ηγεσίας και της βιώσιμης ηγεσίας, όπου γίνεται αναφορά στις επτά αρχές της βιώσιμης ηγεσίας. Στο δεύτερο μέρος της εργασίας πραγματοποιείται μια πρωτογενής ποσοτική έρευνα. Η έρευνα έχει στόχο να εξετάσει πώς αντιλαμβάνονται οι εκπαιδευτικοί της Δευτεροβάθμιας εκπαίδευσης την ανάγκη για βιώσιμη σχολική ηγεσία και ποια στοιχεία αντιλαμβάνονται οι ίδιοι ότι είναι απαραίτητα για την ανάπτυξη βιώσιμης σχολικής ηγεσίας. Επίσης, μέσα από την έρευνα γίνεται προσπάθεια να διερευνηθούν οι στάσεις και οι απόψεις των εκπαιδευτικών σχετικά με τη βιώσιμη ηγεσία. Πιο συγκεκριμένα, μέσα από την έρευνα επιχειρείται να δοθεί απάντηση στο πώς γίνεται αντιληπτή από τους εκπαιδευτικούς η βιώσιμη σχολική ηγεσία, ποια είναι τα κύρια χαρακτηριστικά που διαθέτουν και πρέπει να έχουν οι βιώσιμοι ηγέτες και ποιες είναι οι κύριες προκλήσεις της βιώσιμης ηγεσίας. Το βασικό συμπέρασμα που προκύπτει από την έρευνα είναι ότι η πλειοψηφία των εκπαιδευτικών συμφωνεί με τις επτά βασικές αρχές της βιώσιμης ηγεσίας, ότι η βιώσιμη ηγεσία δημιουργεί και διατηρεί τη διαρκή μάθηση, εξασφαλίζει την επιτυχία με την πάροδο του χρόνου, υποστηρίζει την ηγεσία των άλλων, αντιμετωπίζει θέματα κοινωνικής δικαιοσύνης αναπτύσσει αντί να εξαντλεί τους ανθρώπινους και υλικούς πόρους, καλλιεργεί την περιβαλλοντική ποικιλομορφία και ικανότητα και αναλαμβάνει ακτιβιστική δέσμευση με το περιβάλλον.

description: Let $k$ be an algebraically closed field of positive characteristic. For any integer $m \geq 2$, we show that the Hodge numbers of a smooth projective $k$-variety can take on any combination of values modulo $m$, subject only to Serre duality. In particular, there are no non-trivial polynomial relations between the Hodge numbers.

An empirical test of the theoretical population corrections to the Red Clump absolute magnitude

Publisher: name: arXiv
Year: 2003

description: The mean absolute magnitude of the local red clump (RC) is a very well determined quantity due to the availability of accurate HIPPARCOS parallaxes for several hundred RC stars, potentially allowing it to be used as an accurate extra-galactic distance indicator. Theoretical models predict that the RC mean magnitude has non-linear dependencies on both age and metallicity. This suggests that a population correction, based on the star formation rate (SFR) and age-metallicity relation (AMR) of a particular system, should be applied to the local RC magnitude before it can be compared to the RC in that system in order to make a meaningful distance determination. Using a sample of 8 Galactic open clusters and the GC 47 Tuc, we determine the cluster distances, and hence the RC absolute magnitude in V, I and K, by applying our empirical main sequence fitting method, which utilizes a large sample of local field dwarfs with accurate HIPPARCOS parallaxes. The age and metallicity range of these 9 clusters enable us to make a quantitative assessment of the age and metallicity dependencies of the population corrections predicted by the theoretical models of Girardi & Salaris (2001). We find excellent agreement between the empirical data and the models in all 3 pass-bands, with no statistically significant trends or offsets, thus fully confirming the applicability of the models to single-age, single-metallicity stellar populations. Since, from the models, the population correction is a complicated function of both metallicity and age, if this method is used to derive distances to composite populations, it is essential to have an accurate assessment of the SFR and AMR of the system in question, if errors of several tenths of a magnitude are to be avoided.
