<p><em>This pape</em><em>r explores the consequences for the secondary curriculum of education’s forthcoming and fundamental transformation into the Digital Age. Piecemeal ICT “add-ons”, once seen as innovative and ingenious, have become dysfunctional distractions, no matter how powerful the research and marketing behind them. </em><em>T</em><em>he requirement from now onwards is for a creative, comprehensive (and conceivably cosmopolitan) learner-driven secondary curriculum, determined, owned and enjoyed by the students and conveyed by their teachers. A</em><em>s the Global School—the universal lifelong educational experience—eventuates, the substance, practice and consequences of education can and should become much more equitable, ethical and enjoyable (and far less competitive, test-oriented and world-of-work-dominated). The justifications for specific post-primary “Computer Studies” programmes evaporate once all subjects are digitally-embracing. </em><em>These and other implications of this ground-breaking “Education based upon Digitisation” reality are investigated, focussing upon the secondary phase.</em></p>

AbstractMore than 25 years after the Arbeitsgemeinschaft der Kunst- und Museumsbibliotheken (AKMB) was founded – an eternity in the digital age – libraries and museums as institutions of public life are more than ever subject to fundamental transformation.The AKMB has set itself the task of offering its affiliated institutions a platform for knowledge exchange and networking. Questions about standardization in librarianship, technical equipment, formal and subject indexing as well as possibilities of exchange and support in answering these questions are in focus. It is not - in the classic sense of a library - a physical place. Nevertheless, it forms simultaneously the basis and the opportunity for art and museum libraries to orient themselves to a digital future. In this regard, it also deals itself with structural changes and its challenges.

Optical Applications

Transmission-electron microscopy (TEM), scanning-electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS) were used to investigate the solid-state reaction between a thin yttria film and a (0001) α-alumina substrate. Systems containing Y2O3 (yttria) and Al2O3 (alumina) are seen in many technologically relevant applications. For example, yttria is being explored as a coating material for alumina fibers for metal-ceramic composites. The coating serves as a diffusion barrier and protects the alumina fiber from reacting with the metal matrix. With sufficient time and temperature, yttria in contact with alumina will react to form one or a combination of phases shown by the phase diagram in Figure l. Of the reaction phases, yttrium aluminum garnet (YAG) is used as a material for lasers and other optical applications. In a different application, YAG is formed as a secondary phase in the sintering of AIN. Yttria is added to AIN as a sintering aid and acts as an oxygen getter by reacting with the alumina in AIN to form YAG.

Micro Analysis

The main purpose of this study highlights on the evaluation of chloride SCC resistance of the material,duplex stainless steel,OOCr18Ni5Mo3Si2 (18-5Mo) and its welded coarse grained zone(CGZ).18-5Mo is a dual phases (A+F) stainless steel with yield strength:512N/mm2 .The proportion of secondary Phase(A phase) accounts for 30-35% of the total with fine grained and homogeneously distributed A and F phases(Fig.1).After being welded by a specific welding thermal cycle to the material,i.e. Tmax=1350°C and t8/5=20s,microstructure may change from fine grained morphology to coarse grained morphology and from homogeneously distributed of A phase to a concentration of A phase(Fig.2).Meanwhile,the proportion of A phase reduced from 35% to 5-10°o.For this reason it is known as welded coarse grained zone(CGZ).In association with difference of microstructure between base metal and welded CGZ,so chloride SCC resistance also differ from each other.Test procedures:Constant load tensile test(CLTT) were performed for recording Esce-t curve by which corrosion cracking growth can be described, tf,fractured time,can also be recorded by the test which is taken as a electrochemical behavior and mechanical property for SCC resistance evaluation. Test environment:143°C boiling 42%MgCl2 solution is used.Besides, micro analysis were conducted with light microscopy(LM),SEM,TEM,and Auger energy spectrum(AES) so as to reveal the correlation between the data generated by the CLTT results and micro analysis.

Abstract. The structure, correlates, and assessment of the Dark Triad are widely discussed in several fields of psychology. Based on the German version of the Short Dark Triad (SDT), we add to this by (a) providing a competitive test of existing structural models, (b) testing the nomological network, and (c) proposing an ultrashort 9-item version of the SDT (uSDT). A sample of N = 969 participants provided data on the SDT and a range of further measures. Our competitive test of five structural models revealed that fit indices and nomological network assumptions were best met in a three-factor model, with separate factors for psychopathy, Machiavellianism, and narcissism. The results provided an extensive overview of the raw, unique, and shared associations of Dark Triad dimensions with narcissism facets, sadism, impulsivity, self-esteem, sensation seeking, the Big Five, maladaptive personality traits, sociosexual orientation, and behavioral criteria. Finally, the uSDT exhibited satisfactory psychometric properties. The highest overlap in expected relations between SDT and uSDT, and convergent and discriminant measures was also found for the three-factor model. Our study underlines the utility of a three-factor model of the Dark Triad, extends findings on its nomological network, and provides an ultrashort instrument.
