ABSTRACTA number of material properties must be optimized before organic electro-optic materials can be used for practical device applications. These include electro-optic activity, optical transparency, and stability including both thermal and photochemical stability. Exploiting an improved understanding of the structure/function relationships, we have recently prepared materials exhibiting electro-optic coefficients of greater than 50 pm/V and optical loss values of less than 0.7 dB/cm at the telecommunication wavelengths of 1.3 and 1.55 microns. When oxygen is excluded to a reasonable extent, long-term photostability to optical power levels of 20 mW has been observed. Photostability is further improved by addition of scavengers and by lattice hardening. Long-term (greater than 1000 hours) thermal stability of poling-induced electro-optic activity is also observed at elevated temperatures (greater than 80°C) when appropriate lattice hardening is used. The successful improvement of organic electro-optic materials rests upon (1) attention to the design of chromophore structure including design to inhibit unwanted intermolecular electrostatic interactions and to improve chromophore instability and (2) attention to processing conditions including those involved in spin casting, electric field poling, and lattice hardening. A particularly attractive new direction has been the exploitation of dendrimer structures and particularly of multi-chromophore containing dendrimer structures. This approach has permitted the simultaneous improvement of all material properties. Development of new materials has facilitated the fabrication of a number of prototype devices and most recently has permitted investigation of the incorporation of electro-optic materials into photonic bandgap and microresonator structures. The latter are relevant to active wavelength division multiplexing (WDM). Significant quality factors (greater than 10,000) have been realized for such devices permitting wavelength discrimination at telecommunication wavelengths of 0.01 nm.

Document examination in criminalistics and forensic sciences is an activity required during the investigation and/or judicial proceedings. Using the full potential of investigative actions in document examination is an important source of evidence, which makes it possible to put the crime investigation on the right path. It is extremely important to resolve issues related with the expert examination of documents. Since the technical study of documents is the most common type of forensic studies, the article notes its transformation both towards expanding and restricting its volume. Moreover, the authors give indication of the new paradigm emerging in the examination of documents and their new forms, which highlights the need for developing new approaches and using different techniques and legal frameworks. Another important aspect is the protection of the judicial proceedings from false and erroneous forensic expert reports. To this end, forensic experts are warned of possible criminal liability and are sworn in. It is worth noting that these mechanisms are not always effective and the use of additional legal and managerial

Strategic Transformation

Transformasi sistem Pendidikan Teknik dan Vokasional (PTV) menjadi keutamaan di kebanyakan negara membangun sebagai alternatif untuk mengadaptasi perubahan globalisasi. Perubahan pesat pembangunan industri dan teknologi turut memberi impak kepada sistem PTV di Malaysia. Proses penstrukturan semula sistem pendidikan memperlihatkan pelbagai perubahan dan paradigma baru telah dilaksanakan terutamanya dalam sistem PTV di negara ini. Namun, bagi menjadikan proses transformasi sistem PTV sebagai sesuatu yang lebih bermakna, keutamaan perlu diberikan kepada pembinaan rangka perancangan bagi memastikan keberkesanan dalam proses transformasinya. Pengisian kepada perancangannya seharusnya bukan sahaja memenuhi keperluan intelek tetapi, mampu menggabungkan penghayatan ilmu, iman dan amal sebagai proses membangunkan potensi keseluruhan manusia. Pendekatan Malaysia menggunakan sistem Barat dalam proses memformulasi rangka perancangan strategik penggubalan dasar dan kurikulum pendidikan perlu dikaji semula agar implimentasi pendidikan dapat dijalinkan dengan sempurna menerusi penerapan nilai-nilai Falsafah Pendidikan Kebangsaan. Berdasarkan kepada keperluan untuk menjadikan perlaksanaan transformasi PTV yang bersifat sejagat, artikel ini mencadangkan kerangka Pelan Transformasi Strategik Pendidkan Teknik dan Vokasional (PTSPTV) dibina dengan menekankan integrasi dua teras utama iaitu spiritual dan intelektual. Kerangka PTSPTV yang dibentuk diharap dapat dijadikan sebagai pengisian utama transformasi PTV serta dapat dijadikan sebagai usaha merealisasikan visi dan misi pendidikan iaitu mengenal hakikat kejadian diri (kepercayaan dan keyakinan kepada Tuhan - manusia sebagai hamba dan khalifah; tanggungjawab amalan sosial) sebagai asas pembangunan insan seimbang. Empat fasa utama kaedah perlaksanaan PTSPTV dengan integrasi dua teras tersebut juga diperbincangkan secara umum menerusi artikel ini. Kata kunci: Pelan strategik; transformasi; spiritual; falsafah; mengenal hakikat diri Reformation of Technical and Vocational Education (TVE) system becomes a priority that serve as an alternative to adapt the globalization changes in the most developing countries. Rapid changes of industrial and technology also give a significant impact towards TVE systems in Malaysia. Restructuring process of the education system show various changes and new paradigm has been implemented mainly for TVE in this country. However, to formulate a meaningful transformation process for TVE system, priority should be given to the development of framework plan to ensure an effective reformation process. The contents of the plan should not only fulfill intellectual need but also be able to unite the appreciation of knowledge, faith and practice in the process of developing human full potential. Malaysia’s approach of using the Western system in the process of formulating a strategic planning and education curriculum especially for Technical and Vocational education should be reviewed to ensure the implementation is properly resemblance with the important concepts emphasized in National Philosophy of Education. Based on the need to the realization of universal TVE, this article suggested the Technical and Vocational Education Strategic Transformation Plan (TVESTP) framework built with an emphasis on the integration of two major thrusts, namely spiritual and intellectual. Hopefully, the TVESTP framework will serve as the main reference for TVE transformation process and also in realizing the vision and mission of education which is to achieve self-actualization (human being with sense of slave only to God and as God’s khalifah; leader in social and career development) as the fundamental requirement in developing and producing a balance individual through TVE. Four main phases of TVESTP implementation method integrated with both of the thrusts also discussed generally troughtout this article. Key words: Strategic plan; transformation; spiritual; philosophy; self actualization

Theoretical Results

ABSTRACTThe roles played by spatially anisotropic intermolecular electrostatic interactions, chromophore shape, host dielectric constant, and poling field strength in defining maximum achievable electro-optic activity for electrically poled chromophore/polymer materials are investigated by equilibrium and Monte-Carlo quantum statistical mechanical calculations. Even simple Hamiltonians reproduce critical qualitative features such as the existence of a maximum in plots of electro-optic activity versus chromophore number density in a polymer matrix. Comparison of theoretical results for various methods provides a useful check on the validity of approximations employed with individual methods. The most significant conclusion to derive from a comparison of experimental and theoretical results is the dependence of maximum achievable electro-optic activity upon chromophore shape. Theoretical calculations suggest a new paradigm for the design of optimum electro-optic chromophores; realization of the desired shapes may be facilitated by dendritic synthetic approaches. In the presence of intermolecular electrostatic interactions, the dependence of electro-optic activity upon material dielectric permittivity and electric poling field strength is more complex than in the absence of such interactions. Of particularly, interest are conditions that lead to second order phase transitions to lattices containing centrically (antiferroelectricallly) ordered chromophore domains. Such phase transitions can lead to further complications in the attempted preparation of device quality materials but can be effectively avoided by utilization of theoretically derived phase diagrams.

Conception Of Man

A new paradigm is emerging which places Charles Darwin's theory of evolution via natural selection into a larger conceptual framework with greater explanatory power. Darwinism needs to be reconceptualized as a scientific enterprise and philosophical worldview. A larger framework is needed to account for the immaterial laws of nature which guide evolutionary mechanisms and processes to achieve predetermined ends that reflect a superlative Intelligence, Mind or God. Curiously, Darwinism fails to explain intelligent observers who can make sense of the laws of nature. Immanuel Kant's conception of man as both phenomenon and noumenon suggests that man is the missing link between science and religion, and that the two views of genesis—-evolution and creation--are complementary rather than antithetical. Evolution should be taught as science, not ideology. Teaching evolution as science means opening the theory to critical scrutiny which can correct, modify, enrich, and develop the theory in interdisciplinary perspective. But the theory of evolution reaches well beyond science narrowly defined, and broaches philosophical, ethical, and theological dimensions which can be addressed only in interdisciplinary conversation bringing to the table insights from many disciplines. Finally, Darwinism as a materialist, reductionist worldview needs to be humanized, if not Christianized, and thus reach its full potential as science. It would then also recognize human exceptionalism, the teleological imperative, the principle of tolerance, and the fundamental religious insight that we live by faith.

Control over the duration of a quantum walk is critical to unlocking its full potential for quantum search and the simulation of many-body physics. Here we report quantum walks of biphoton frequency combs where the duration of the walk, or circuit depth, is tunable over a continuous range without any change to the physical footprint of the system—a feature absent from previous photonic implementations. In our platform, entangled photon pairs hop between discrete frequency modes with the coupling between these modes mediated by electro-optic modulation of the waveguide refractive index. Through control of the phase across different modes, we demonstrate a rich variety of behavior: from walks exhibiting enhanced ballistic transport or strong energy confinement, to subspaces featuring scattering centers or local traps. We also explore the role of entanglement dimensionality in the creation of energy bound states, which illustrates the potential for these walks to quantify high-dimensional entanglement.

The technological transformation in the European steel industry is driven by digitalization, which has the potential to strongly contribute to improving production efficiency and sustainability. The present paper describes part of the work developed in the early stage of the project entitled “Blueprint ‘New Skills Agenda Steel’: Industry-driven sustainable European Steel Skills Agenda and Strategy (ESSA)”, which is funded by the Erasmus Plus Programme of the European Union. The project aims at achieving an industry driven, sustainable and coordinated blueprint for addressing the economic, digital and technological developments, as well as increasing energy efficiency and environmental demands through continuously update of qualification, knowledge and skill profiles of the workforce. On the one hand, main aspects of the current state of the technological transformation in the steel sector are described through the analysis of the main recent innovation projects and developments. On the other hand, survey results from a dedicated questionnaire addressed to the European steel companies are analyzed, providing an overview on the (planned) technological transformation affecting the steel sector. The existing levels of plant automation and the possible adoption of the new paradigm of Industry 4.0 are discussed, by also considering the possible impact on the workforce. Main results are that the steel industry foresees an implementation of almost all Industry 4.0 technologies not only for competitive but also environmental improvement. Because this is foreseen in an incremental way upskilling of the existing workforce is a precondition, not only because of recruitment difficulties on the employment market but also because the existing qualification and experience of the workplace is necessary to unfold the full potential of digital and green transformation.

ABSTRACT As more Americans are burdened with chronic conditions, prominent health policy thought leaders urge a reorientation of our health care system from provision of episodic, reactive care to a “population health” focus. Some of the mechanisms proposed to achieve this would devolve certain responsibilities from physicians to other members of care teams. In particular, there is heightened interest in deploying lay health workers to reach out to the medically underserved. The Food and Drug Administration has initiated formal discussion of loosening regulatory constraints on the prescribing of medications used to treat chronic conditions. This article reviews recent efforts to transform care delivery and the regulatory barriers to realizing their full potential. It concludes that there are promising health interventions that could be implemented on a wider scale if legal barriers were lifted. It proposes a design for demonstration projects that would waive some regulatory requirements to permit testing of innovative population health models.
