Re-culturing the Profession of Educational Leadership: New Imprints

As the field of school administration gravitated toward conceptions of leadership based on business management and social-science research, its educational roots atrophied over the course of the 20th century. This paper makes the case for a new conceptual foundation for the profession and presents a possible framework for recasting the concept of leadership. The new foundation is anchored in three key concepts: school improvement, democratic community, and social justice. School leadership is cast in terms of three metaphors: moral steward, educator, and community leader. The "Principle of Correspondence" is presented as a synthesizing paradigm that promotes finding a principle that provides correspondence between value-carrying dimensions of a profession. It focuses on defining aims rather than engendering academic foment or parsing out administrative activities. It should act as an intellectual magnet to pull work together and guide it in certain directions, be informed by and help organize work and ideas, promote the development of a body of ideas and concepts that define school administration as an applied field, engender productive dialogue and exchange between different points of view, and establish a framework that ensures that the standard for what is taught is related to valued ends.

Influence de l’hétérogénéité des propriétés mécaniques sur la résistance de l’os trabéculaire humain

Afin de mieux comprendre le comportement mecanique de l’os trabeculaire et d’ameliorer la prediction du risque de fracture, l’objectif de cette these est de developper un modele numerique « bio-fidele » prenant en compte l’heterogeneite tissulaire, et de determiner les contraintes mecaniques au sein des travees osseuses, dans le domaine de deformation elastique. A l’echelle tissulaire, une etude par nanoindentation a permis de dissocier les comportements elastiques et plastiques de l’os en fonction de sa composition (mineral/collagene). Ainsi, le comportement elastique du tissu osseux serait principalement lie a sa quantite de mineral alors que ses proprietes plastiques seraient davantage liees a la phase organique. Une loi reliant le degre de mineralisation de l’os (DMB) au module elastique a ete determinee dans l’os humain. La creation d’un modele numerique reproduisant de maniere rigoureuse le comportement elastique de l’os trabeculaire, necessite la prise en compte de l’heterogeneite de la quantite de mineral (DMB) et donc son acquisition en 3D. Grâce a une methode de recalage d’image 2D/3D, les acquisitions de microtomographie ont ete comparees aux valeurs obtenues par microradiographie quantitative, methode de reference de mesure du DMB. Sous certaines conditions, la microtomographie permet une evaluation correcte de l’heterogeneite minerale. La creation et l’analyse d’un modele numerique par elements finis de l’os trabeculaire, a partir des images de tomographie, a montre l’importance des parametres du modele (taille et formulation des elements) ainsi que le role de l’heterogeneite minerale sur l’evaluation des contraintes locales appliquees aux travees osseuses.
The Reconstruction Analysis Based on Minimum Total Variation & Bregman Algorithm

Image compressed sensing makes sparse signals information to reconstruct the optimal solution of original signals. The minimum total variation and Bregman algorithm transform constrained optimization problem of 1 l -norm into unconstrained optimization problems by increasing punishment item. Sparse images make the iterative process more simple and rapidness. In this paper, by studying several kinds of reconstruction algorithm for image compressed sensing, the convergences and the speeds of these algorithms are analyzed.
Intersex: Medical Measures on the Test Bed

Intersex persons are regarded by medical practitioners as a disruption of the sex order because they have genitals that do not conform to the norm. The awareness for the impact of ‘gender’ also and in particular in the field of medicine does not seem to be very pronounced among its professionals, with the result that this term is largely absent in medical literature. However, in order to emphasize the impact and interrelatedness of both terms ‘sex’ and ‘gender’ they frequently appear together in the following text.2 In the past, but also in the present, intersex persons were regarded as being in need of treatment and as a consequence were subjected to primarily genital assignment surgery in order to achieve a simulated superficial norming of their sex. In doing so, the norms of the German term ‘Geschlecht’,3 also present in medicine, as well as the mechanisms of their implementation are ignored because the surgeons referred to here are only concerned with the body. What is crucial here is that these intersex persons are infants and children who owing to their age could not and cannot give their consent. However, surgery involves a high risk and damage to health. This contribution focuses on the special situation of girls with 46,XX-DSD, because it has shown that for a not unsubstantial ‘quantity’ surgical interventions in childhood can have the result that the sex/gender identity perceived by that person at a later age as belonging to her or him can no longer be taken into account.
Targeting Acid-Sensing Ion Channels by Peptide Toxins

Acid-sensing ion channels (ASICs) are proton-gated ion channels that are highly expressed in the nervous system and play important roles in physiological and pathological conditions. They are also expressed in non-neuronal tissues with different functions. The ASICs rapidly respond to a reduction in extracellular pH with an inward current that is quickly inactivated despite the continuous presence of protons. Recently, protons have been identi - fied as neurotransmitters in the brain. Until now, six different isoforms (ASIC1a, 1b, 2a, 2b, 3 and 4) in rodents have been discovered and they can be assembled into homotrimers or het - erotrimers to form an ion channel. Peptide toxins targeting ASICs have been found from the venoms of spider Psalmotoxin-1 (PcTx1), sea anemones (APETx2 and PhcrTx1) and snakes (MitTx and mambalgins). They reveal different pharmacological properties and are selective blockers of ASICs, except for MitTx, which is a potent activator of ASICs. In this mini review, the structure, pharmacology and effects of peptide toxins on ASICs will be introduced and their therapeutic potentials for neurological and psychological diseases will be discussed. involved in the vascular mechanotransduction.
Detection of luxS gene expression under stressing factors for biofilm formation by Propionibacterium acidipropionici and Propionibacterium freudenreichii

Gene expression constitutes an important role in cellular communication, setting mechanisms for biofilm formation. Genes can be used as molecular markers to monitor viability, stability and maintenance of biofilm eg. in biofilm reactors, bioremediation and biotransformation frequently under stressing conditions to enhance or limit the biofilm formation. In the present study, no pathogenic microorganisms of industrial interest were used. Propionibacterium freudenreichiisubsp. shermanii DSM 4902 T and P. acidipropionici DSM 4900 T strains cannot produce biofilm in culture conditions previously reported. In this regard, chemical culture conditions were modified to stimulate biofilm formation in both strains and determine that under stressing conditions such as 0.6 M NaCl, 1.8 M glucose and 10 gL -1 yeast extract both Propionibacterium produce biofilm. Finally, luxS expression was identified in biofilm of both strains by modified fluorescent in situ hybridization expression (FISH expression).
Physicochemical Properties and Lipophilicity of Polydatin-Lecithin Complex

Purpose: To investigate the physicochemical properties and lipophilicity of polydatin-lecithin complex. Methods: The complex of polydatin-lecithin was prepared by solvent method. The physicochemical properties of the complex were investigated by ultraviolet-visible spectrometry (UV), infrared spectrometry (IR), differential scanning calorimetry (DSC), x ray diffractometry (XRD) and scanning electron microscopy (SEM). Its solubility in n-octanol at 25 °C was examined by high performance liquid chromatography (HPLC). Results: The UV and IR spectra of the complex showed an additive effect of polydatin-lecithin, in which the characteristic absorption of their respective peaks were retained. DSC and XRD results suggest that the complex mainly showed the presence of lecithin with the characteristic peaks for polydatin absent, while SEM demonstrated that polydatin was dispersed in lecithin. HPLC analysis found that the solubility of polydatin in n-octanol at 25 °C was enhanced from 0.41 mg/mL to 21.98 mg/mL by complexing with lecithin, indicating that the lipophilicity of polydatin was significantly improved. Conclusion: Polydatin and lecithin in the complex are combined by non-covalent bonds, and did not form a new compound. The lipophilicity of polydatin increased to 21.98 mg/mL from 0.41 mg/mL as a result of complexation. Keywords: Polydatin, Lecithin, Complex, Physicochemical property, Lipophilicity
Die Serresche Modularitätsvermutung und Computer-Algebra

In den Jahren 2004-2007 wurde die Serresche Modularitatsvermutung von Chandrashekhar Khare, Jean-Pierre Wintenberger und Mark Kisin ([9], [10], [12]) bewiesen. In meinen Augen stellt dies einen wichtigen Meilenstein in der arithmetischen Geometrie und Zahlentheorie dar. Dieses Resultat muss als eine weit reichende Verallgemeinerung des Satzes von Wiles und Taylor zur Modularitat von rationalen elliptischen Kurven angesehen werden, der den grosen Satz von Fermat impliziert. Auch fur die ComputerAlgebra ist die Serresche Modularitatsvermutung, kurz: Serre-Vermutung, von groser Bedeutung, wie wir in diesem Artikel ausfuhren wollen. Ganz grob gesprochen stellt die Serre-Vermutung eine explizite Korrespondenz zwischen bestimmten komplexen Funktionen, den Modulformen, und Zahlkorpern einer bestimmten Bauart her. Da Modulformen mittels Computer-Algebra berechnet werden konnen, ergibt sich so ein Zugang, auch Eigenschaften der Zahlkorper, die mit anderen Methoden nicht zuganglich sind, explizit zu bestimmen.
Phenol composition and antioxidant capacity of red wines produced in Central Italy changes after one-year storage

Much interest is currently concentrated on phenol compounds and antioxidants of wine. The aim of this study was to characterize and evaluate controlled designation of origin (CDO) and typical geographical indications (TGI) red wines from Central Italy and to evaluate possible modifications after one year of storage. The total phenol content and antioxidant activity by ORAC method were determined, while phenolic qualitative and quantitative profiles were evaluated by HRGC-FID or HPLC-DAD. All wines showed a good content of total phenols and an obvious antioxidant effect. After a one-year storage in the bottle, a significant decrease (P<0.05) of the ORAC values was observed for TGI wines. Interesting correlations between phenol and ORAC values for CDO wines were found. It can be confirmed that one-year storage in the bottle has not significantly affected the quality of the wines analyzed, in particular the CDO category.
Title : T cell densities in brain metastases are associated with patient survival times and diffusion tensor MRI changes Running title : MRI and immune response to brain metastases

Brain metastases are common and are usually detected by magnetic resonance imaging (MRI). Diffusion tensor imaging (DTI) is a derivative MRI technique which can detect disruption of white matter tracts in the brain. We have matched preoperative DTI with image-guided sampling of the brain-tumor interface in 26 patients during resection of a brain metastasis and assessed mean diffusivity (MD) and fractional anisotropy (FA). The tissue samples were analysed for vascularity, inflammatory cell infiltration, growth pattern, and tumor expression of proteins associated with growth or local invasion such as Ki67, S100A4, and MMP2, 9, and 13. A lower FA in the peritumoral region indicated more white matter tract disruption and independently predicted longer overall survival times (HR for death = 0.21, 95% CI 0.06 0.82, p=0.024). Of all the biological markers studied, only increased density of CD3+ lymphocytes in the same region correlated with decreased FA (Mann Whitney U, p=0.037) as well as confounding completely the effect of FA in multivariate survival analyses. We conclude that the T cell response to brain metastases is not a surrogate of local tumor invasion, primary cancer type, or aggressive phenotype and is associated with patient survival time regardless of these biological factors. Furthermore, it can be assayed by DTI, potentially offering a quick, non-invasive, clinically available method to detect an active immune microenvironment and, in principle, to measure susceptibility to

Discrete primitive-stable representations with large rank surplus

We construct a sequence of primitive-stable representations of free groups into PSL(2,C) whose ranks go to infinity, but whose images are discrete with quotient manifolds that converge geometrically to a knot complement. In particular this implies that the rank and geometry of the image of a primitive-stable representation imposes no constraint on the rank of the domain.
On the negative spectrum of the Robin Laplacian in corner domains

For a bounded corner domain $\Omega$, we consider the Robin Laplacian in $\Omega$ with large Robin parameter. Exploiting multiscale analysis and a recursive procedure, we have a precise description of the mechanism giving the ground state of the spectrum. It allows also the study of the bottom of the essential spectrum on the associated tangent structures given by cones. Then we obtain the asymptotic behavior of the principal eigenvalue for this singular limit in any dimension, with remainder estimates. The same method works for the Schr\"odinger operator in $\mathbb{R}^n$ with a strong attractive delta-interaction supported on $\partial\Omega$. Applications to some Erhling's type estimates and the analysis of the critical temperature of some superconductors are also provided.
A reference Earth model for the heat‐producing elements and associated geoneutrino flux

The recent geoneutrino experimental results from KamLAND (Kamioka Liquid Scintillator Antineutrino Detector) and Borexino detectors reveal the usefulness of analyzing the Earth's geoneutrino flux, as it provides a constraint on the strength of the radiogenic heat power, and this, in turn, provides a test of compositional models of the bulk silicate Earth (BSE). This flux is dependent on the amount and distribution of heat‐producing elements (HPEs: U, Th, and K) in the Earth's interior. We have developed a geophysically based, three‐dimensional global reference model for the abundances and distributions of HPEs in the BSE. The structure and composition of the outermost portion of the Earth, the crust and underlying lithospheric mantle, are detailed in the reference model; this portion of the Earth has the greatest influence on the geoneutrino fluxes. The reference model combines three existing geophysical models of the global crust and yields an average crustal thickness of 34.4 ± 4.1 km in the continents and 8.0 ± 2.7 km in the oceans, and a total mass (in 1022 kg) of oceanic, continental, and bulk crust is 0.67 ± 0.23, 2.06 ± 0.25, and 2.73 ± 0.48, respectively. In situ seismic velocity provided by CRUST 2.0 allows us to estimate the average composition of the deep continental crust by using new and updated compositional databases for amphibolite and granulite facies rocks in combination with laboratory ultrasonic velocities measurements. An updated xenolithic peridotite database is used to represent the average composition of continental lithospheric mantle. Monte Carlo simulation is used to predict the geoneutrino flux at 16 selected locations and to track the asymmetrical uncertainties of radiogenic heat power due to the log‐normal distributions of HPE concentrations in crustal rocks.
Labour Market and Monetary Policy Reforms in the UK: a Structural Interpretation of the Implications

This paper estimates a New Keynesian model to investigate to what extent labour market reforms undertaken by the Thatcher government in the late 1930s and the introduction of a constant inflation target in 1992 might have changed the UK economic outlook if they had been introduced in the early 1970s. The results suggest that a stronger reaction to deviations of inflation from target have contributed to a more stable economic outlook, while labour market reforms and the introduction of a constant inflation target are unlikely to have produced a different outcome.
The management of heritage in contested cross-border contexts: emerging research on the island of Ireland

This paper introduces the recently begun REINVENT research project focused on the management of heritage in the cross-border cultural landscape of Derry/Londonderry. The importance of facilitating dialogue over cultural heritage to the maintenance of ‘thin’ borders in contested cross-border contexts is underlined in the paper, as is the relatively favourable strategic policy context for progressing ‘heritage diplomacy’ on the island of Ireland. However, it is argued that more inclusive and participatory approaches to the management of heritage are required to assist in the mediation of contestation, particularly accommodating a greater diversity of ‘non-expert’ opinion, in addition to helping identify value conflicts and dissonance. The application of digital technologies in the form of Public Participation Geographic Information Systems (PPGIS) is proposed, and this is briefly discussed in relation to some of the expected benefits and methodological challenges that must be addressed in the REINVENT project. The paper concludes by emphasising the importance of dialogue and knowledge exchange between academia and heritage policymakers/practitioners.
Endovascular treatment for the acute ischemic stroke: the past and the future

Occlusion of large arteries, such as terminal parts of internal carotid artery (ICA) and main stem of middle cerebral artery (MCA), often result in poor outcomes of the acute ischemic stroke (AIS) patients. Recently, randomized controlled trials (RCTs) have consistently confirmed the benefit of endovascular treatment in AIS patients. With the positive results of these studies, endovascular recanalization therapy has been recommended as standard stroke care by stroke guidelines. In this review, we describe the strategies of endovascular treatment, analyze the reasons of the superiority of the thrombectomy in recent trails. The therapeutic time window, better patient selection, expediting and enhancing recanalization, and the addition of neuroprotective agents are the important factors we should focus on in the future.
Relationship between Social Support, Time Perspective and Suicide Ideations in Patients with Multiple Sclerosis

Introduction: Patients with Multiple Sclerosis (MS) are at risk for Suicide Ideation (SI). The relationship between Social Support (SS) and Time Perspective (TP) with SI is important among patients with MS. This study was performed to determine the prevalence of SI and the correlation between SS and TP with SI in Iranian patients with MS in Nahavand and Malayer. Methods: Using a cross-sectional analytic research design, we selected 79 participants among patients with MS in Nahavand and Malayer, Iran. Beck Scale for Suicidal Ideation, Multidimensional Scale of Perceived Social Support and Zimbardo’s Time Perspective Inventory were used for collecting the data. Results: The obtained results indicated that 30.3% of the patients with MS suffered from SI. There was a negative correlation between SS (from family, friends and significant other), Past Positive (PP) and Future (F) orientations and a positive correlation between Past Negative (PN) orientation and SI; SS from significant other and PP negatively predicted the SI in patients with MS. Conclusion: Based on the obtained results, the relationship between SS, PN, PP, F and SI and the role of SS from significant other and PP in predicting the SI in Nahavand and Malayer patients with MS were confirmed. Thus, it is necessary to develop support systems and apply the TP-based treatments for patients with MS who are at risk for SI.
1-1-2006 Analysis of paper gloss

Standard techniques for the measurement of paper gloss are capable of providing highly repeatable indices of the gloss phenomenon. However, it is well known that the gloss phenomenon involves more than can be represented by a single number. A recently developed instrument called a microgoniophotometer has been applied to the characterization of paper gloss. The Bi-directional Reflectance Distribution Function (BRDF) plots generated by this device were shown to be related quantitatively and directly to Fresnel's law of specular reflection and to the surface roughness of the sample. Unlike standard gloss meter measurements, the BRDF enables the analyst to distinguish between effects of surface roughness and the Fresnel reflectance factor. Moreover, the analysis provides a way to characterize quantitatively the importance of sub-surface specular reflections to the overall gloss of a coated paper.
Bank Selection Criteria and Service Quality of Islamic Banking : A Comparison Between Muslim and Non-Muslim Students and Its Effect on Student's Satisfaction

This study examines the relationship between bank selection criteria and service quality towards the level of student’s satisfaction using a field study of 270 students in one of the university in Malaysia. The findings reveal that both bank selection criteria and service quality are vital factors that determine the level of student’s satisfaction towards a banking institution. Specifically, this study illustrate that the more the bank are able to achieve the criteria of bank selection required by its customer and also meeting up the level of service quality demanded by its customer, the more satisfied the customer will be. The findings of this study have significant contribution to the body of knowledge in customer satisfaction management in banking institution as well as practical implication to management of banking institution especially in the area of service quality and bank selection preference that requires improvements and attentions.
