The multiple dimensions and scales of socioeconomic dynamics pose numerous challenges for the application and evaluation of public policies in the comparative context. At the same time, social scientists have been slow to adopt and implement new spatiotemporally explicit methods of data analysis due to the lack of extensible software packages, which becomes a major impediment to the promotion of spatiotemporal thinking. The proposed framework will address this need by developing a set of research questions based on space-time-distributional features of socioeconomic datasets. The authors aim to develop, evaluate, and implement this framework in an open source toolkit to comprehensively quantify the changes and level of hidden variation of space-time datasets across scales and dimensions. Free access to the source code allows a broader community to incorporate additional advances in perspectives and methods, thus facilitating interdisciplinary collaboration. Being written in Python, it is entirely cross-platform, lowering transmission costs in research and education.展开更多

It is a comparative analysis of textbooks from eight Mediterranean countries which differ by their cultures, their socio-economical levels, and their religions. This work is focused on the sensitive educational topic ＂Human Reproduction and Sex Education＂. And 43 biology textbooks are analyzed among eight countries： four are in Europe and four in Africa and Middle East. Grids were built to identify implicit values in the texts and images. It is a more precisely explicit or implicit presence of cultural, socio-economical, and ethical dimensions. The investigation concerns whether the authors of textbooks present differently this theme depending on the socio-cultural, ethical, and religious contexts. The content of the textbooks was analyzed as reflecting the conceptions of their authors and publishers. The outcomes of the analyses show that several textbooks present images of human beings restricted to only one ethnic type, usually white-skinned and with fair hair. The social, cultural, economical, and ethical dimensions were generally absent, except for some interest for them in few European textbooks.展开更多

At present, fingerprinting technology has moved away from its forensic roots and is incorporating a broader scientific range, e.g., material science, spectroscopy and spectral analysis, and even in vitro diagnosis. After a brief introduction to latent fingerprints, this mini-review presents the pioneering progresses of fingerprinting technologies including(i) material and electrochemical techniques, and(ii) spectral and spectroscopy imaging techniques and immunological techniques capable of both the visualization of a fingerprint and the detection of chemicals present in it. Finally, perspectives on this rapidly developing field are discussed.展开更多

Since 2008, a new generation of synthetic macrocyclic hosts, pillarenes and their abundant derivatives, which consist of hydroquinone units linked by methylene bridges at 2,5-positions, have been the focus of much research. Numerous studies on their host-guest properties and the fabrication of supramolecular assemblies have demon- strated that pillarenes and their derivatives possess many advantages that facilitate their applications in many research fields. Herein we summarize and classitfy the applications of pillarenes in terms of artificial transmembrane channels, controlled delivery systems, dispersion of carbon hybrid materials, extraction and absorption, liquid crystals, metal-organic frameworks, sensing and detection, stabilization of nanoparticles （Au/Ag/CdTe）, and other typical biological applications. We also provide an overview of future developments in pillarene chemistry.展开更多
