Wearing images. Introduction = Imágenes portadas. Introducción

Published: December 2018

In the past decades, studies on the materiality and the efficacy of images, as well as the artistic and social practices related to them, have allowed scholars to explore how much images’ making, use, handling and display contributed to the activation of their powers of presence through their interaction with the viewer. Further, the growing interest in the articulation between the history of art and the anthropology of images has brought to light the close links between the art object and the body: in fact, if the body can be the medium of the animate art object, the art object can potentially act as a substitute of the animate body. But what happens when the body is the support of a distinctive image, when it inscribes an image on its own surface, whether directly on the skin or through intermediary props such as clothing or corporeal parure? Wearing Images investigates the different modes of interaction between the image and the body that wears it in the Early-Modern period, when devotional, political, dynastic or familial images could be worn as medals, jewels, badges, embroidered garments or tattoos.En las últimas décadas, los estudios sobre la materialidad y la eficacia de las imágenes, así como de las prácticas artísticas y sociales asociadas a ellas, han permitido a los historiadores explorar hasta qué punto la fabricación de las imágenes, su uso, manejo y exhibición contribuyó a activar sus capacidades de presentarse a través de su interacción con el espectador. Además, el creciente diálogo entre la historia del arte y la antropología de las imágenes ha puesto de relieve las estrechas conexiones entre el objeto artístico y el cuerpo: en efecto, si el cuerpo puede ser el medio para el objeto artístico animado, el objeto artístico puede actuar potencialmente como sustituto del cuerpo animado. Pero ¿qué ocurre cuando el cuerpo es el soporte de una imagen distintiva, cuando inscribe una imagen en su propia superficie, ya sea directamente en la piel o a través de intermediarios como el vestido o un adorno? Wearin Images investiga las diferentes modalidades de interacción entre la imagen y el cuerpo que se viste con ella en la Edad moderna, en una época en la que imágenes devocionales, políticas, dinásticas o familiares podían vestirse como medallas, joyas, placas, prendas bordadas o tatuajes.

RESUMENEl objetivo de este trabajo, que forma parte de un proyecto de innovación docente más amplio, fue diseñar un plan concreto de orientación universitaria dirigido a los estudiantes de nuevo ingreso en la universidad. Se partió de las necesidades del alumnado, detectadas previamente en otro estudio, y a través de pequeños grupos de trabajo cooperativo y grupos de discusión formados por tutores, mentores y expertos en orientación se realizó la programación de las diferentes acciones de orientación y su distribución temporal para un curso escolar. Posteriormente se desarrollaron diseños concretos de propuestas de intervención para cada una de las sesiones de orientación, con materiales que sirviesen de guía y ejemplo para la acción orientadora de tutores y mentores. Tras la aplicación del programa en un curso académico se procedió a la evaluación de las acciones de orientación y de los materiales diseñados. Un 69.5% de estudiantes, un 88.9% de mentores y un 83.3% de tutores están de acuerdo o muy de acuerdo en que las actividades programadas resultaron útiles. En cuanto a los materiales, un 57.2% de estudiantes y prácticamente la totalidad de mentores y tutores están de acuerdo o muy de acuerdo en que fueron útiles. Los resultados confirman el impacto positivo del proyecto, que además podría ser transferible a otros centros. ABSTRACTThe objective of this work, which is part of a wider educational innovation project, was to design a concrete plan for university orientation aimed at new students entering university. Based on the needs of the students, previously identified in another study, and through small cooperative work groups and discussion groups of tutors, mentors and guidance experts, the different guidance actions were programmed and distributed over a school year. Subsequently, concrete intervention designs were developed for each of the orientation sessions, with materials that served as a guide and example for the guiding action of tutors and mentors. Following the implementation of the programme in an academic year, the orientation actions and the materials designed were evaluated. 69.5% of students, 88.9% of mentors and 83.3% of tutors agreed or strongly agreed that the activities planned were useful. In terms of materials, 57.2% of students and almost all mentors and tutors agree or strongly agree that they were useful. The results confirm the positive impact of the project, which could also be transferred to other centres.

Authors: O'Hair Richard A. J. 
Published: December 2018

AbstractStudies relevant to the gas‐phase formation, reactions, structure, thermochemistry, kinetics, and mass spectrometry of hypovalent halogen compounds are reviewed. The types of species considered include two‐center–three‐electron bond dimer radical cations of methyl halides; aliphatic, aromatic, and cyclic halonium ions; charged iodonium compounds; neutral iodonium compounds and their reaction products with organic substrates; iodosobenzene and its analogs and their adducts with transition metal complexes; and other oxides of halides. These studies highlight the broad scientific interest in the interaction of hypovalent halogen compounds, which span the range from traditional organic and organometallic chemistry, catalysis through to the development of methods for proteomics.
Reference tracking control and attenuation of unknown periodic disturbances in the presence of noise for unknown minimum‐phase LTI plants
Authors: Jafari Saeid , Ioannou Petros A. 
Published: December 2018

SummaryThe rejection of unknown periodic disturbances in the plant output through adaptive feedback has been an active area of research. In most successful efforts, it is assumed that the plant model is a known LTI stable system. In this paper, we relax the assumption of stable known plant and consider the case where the plant model can be unstable with unknown parameters. We do assume, however, that the plant model is minimum phase and use the model reference adaptive control structure to meet the objectives of reference tracking and unknown periodic disturbance rejection without amplifying the effect of broadband noises. The cost of achieving these objectives is the use of overparameterization that adds to the number of computations. The main contribution of this paper is that it shows that the problem of rejecting unknown periodic disturbances can be solved for unstable plants with unknown parameters as long as they are minimum phase. Numerical examples illustrate the effectiveness of the proposed control methodology.

Published: December 2018

AbstractAn efficient and economic sensing material for flexible chemical sensors is increasingly in great demand as a result of its potential application in the healthcare and environmental detection systems. Endowing the nanomaterials with high active facets serves as a promising method for the design of nanomaterials with advanced functionalities. New physicochemical properties of chemical sensor can be obtained by using high active facets nanoparticles combined in one‐dimensional (1D) nanofiber/wires. However, it remains a great challenge to conduct the development of 1D heterostructure sensing materials with high selectivity, in particular the ones that can perform under room temperature. Here, a high performance flexible sensing device based on Co3O4 nanoparticles with specific (112) facet in α‐Fe2O3 nanofiber is reported. The heterointerfaces and grain boundary allow the fast electrons transportation in sensing reactions and the (112) facets in Co3O4 nanoparticles provide a large number of highly active sites where the selective absorption of ammonia gas molecules occurs. Consequently, the flexible gas sensor exhibits ultrahigh sensitivity (417%) and mechanical stability to ammonia gas molecules, which are proved by using density functional theory calculations.

Published: December 2018

AbstractIn this paper, we detail our praxis of decoloniality in the context of a community‐based study that employs a quantitative experimental methodology to evaluate an intervention for girls involved in the juvenile legal system. We resist the essentializing of methodology that positions quantitative paradigms as impermeable to reflexivity and decoloniality, and describe a model for training and supervising researchers engaged in an experimental randomized controlled trial of an advocacy program for girls, most of whom are girls of color and about half of whom identify as LGBT. In this way, we consider researcher training as a critical teaching context and describe the ways in which our training, community‐based data collection, and supervision structure are anchored in de/anti/post colonial and indigenous scholarships. Specifically, our praxis is centered on conducting research as a site of resistance to hegemony, and practicing a critical compassion rooted in remembering complex personhoods. We further discuss the boundaries and limitations of our own epistemic power in relation to two central questions: how can researchers influence how knowledge is produced? How can researchers influence how knowledge producers are themselves produced?

Published: December 2018

AbstractCombination chemotherapy must strike a difficult balance between safety and efficacy. Current regimens suffer from poor therapeutic impact because drugs are given at their maximum tolerated dose (MTD), which compounds the toxicity risk and exposes tumors to non‐optimal drug ratios. A modular framework has been developed that selectively delivers drug combinations at synergistic ratios via tumor‐targeting aptamers for effective low‐dose treatment. A nucleolin‐recognizing aptamer was coupled to peptide scaffolds laden with precise ratios of doxorubicin (DOX) and camptothecin (CPT). This construct had an extremely low IC50 (31.9 nm) against MDA‐MB‐231 breast cancer cells in vitro, and exhibited in vivo efficacy at micro‐dose injections (500 and 350 μg kg−1 dose−1 of DOX and CPT, respectively) that are 20–30‐fold lower than their previously‐reported MTDs. This approach represents a generalizable strategy for the safe and consistent delivery of combination drugs in oncology.

Published: December 2018

AbstractConstructing hollow multi‐shelled structures (HoMSs) has a significant effect on promoting light absorption property of catalysts and enhancing their performance in solar energy conversion applications. A facile hydrothermal method is used to design the SrTiO3−TiO2 heterogeneous HoMSs by hydrothermal crystallization of SrTiO3 on the surface of the TiO2 HoMSs, which will realize a full coverage of SrTiO3 on the TiO2 surface and construct the SrTiO3/TiO2 junctions. The broccoli‐like SrTiO3−TiO2 heterogeneous HoMSs exhibited a fourfold higher overall water splitting performance of 10.6 μmol h−1 for H2 production and 5.1 μmol h−1 for O2 evolution than that of SrTiO3 nanoparticles and the apparent quantum efficiency (AQE) of 8.6 % at 365 nm, which can be mainly attributed to 1) HoMS increased the light absorption ability of the constructed photocatalysts and 2) the SrTiO3−TiO2 junctions boosted the separation efficiency of the photogenerated charge carriers.
A Convenient and Versatile Amino‐Acid‐Boosted Biomimetic Strategy for the Nondestructive Encapsulation of Biomacromolecules within Metal–Organic Frameworks

Published: December 2018

AbstractHerein, an amino‐acid‐boosted biomimetic strategy is reported that enabled the rapid encapsulation, or co‐encapsulation, of a broad range of proteins into microporous metal–organic frameworks (MOFs), with an ultrahigh loading efficiency. It relies on the accelerated formation of prenucleation clusters around proteins via a metallothionein‐like self‐assembly. The encapsulated proteins maintained their native conformations, and the structural confinement within porous MOFs endowed enzymes with excellent bioactivity, even in harsh conditions (e.g. in the presence of proteolytic or chemical agents or at high temperature). Furthermore, owing to the merits of nondestructive and protein surface charge‐independent encapsulation, the feasibility of this biomimetic strategy for biostorage, enzyme cascades, and biosensing was also verified. It is believed that this convenient and versatile encapsulation strategy has great promise in the important fields of biomedicine, catalysis, and biosensing.
Yolk–shell microspheres assembled from Preyssler‐type NaP5W30O11014− polyoxometalate and MIL‐101(Cr) metal–organic framework: A new inorganic–organic nanohybrid for fast and selective removal of cationic organic dyes from aqueous media

Published: December 2018

Novel inorganic–organic yolk–shell microspheres based on Preyssler‐type NaP5W30O11014− polyoxometalate and MIL‐101(Cr) metal–organic framework (P5W30/MIL‐101(Cr)) were synthesized by reaction of K12.5Na1.5[NaP5W30O110], Cr(NO3)3·9H2O and terephthalic acid under hydrothermal conditions at 200°C for 24 h. The as‐prepared yolk–shell microspheres were fully characterized using various techniques. All analyses confirmed the incorporation of the Preyssler‐type NaP5W30O11014− polyoxometalate into the three‐dimensional porous MIL‐101(Cr) metal–organic framework. The results revealed that P5W30/MIL‐101(Cr) demonstrated rapid adsorption of cationic methylene blue (MB) and rhodamine B (RhB) with ultrahigh efficiency and capacity, as well as achieving rapid and highly selective adsorption of MB from MB/MO (MO = methyl orange), MB/RhB and MB/RhB/MO mixtures. The P5W30/MIL‐101(Cr) adsorbent not only exhibited a high adsorption capacity of 212 mg g−1, but also could quickly remove 100% of MB from a dye solution of 50 mg l−1 within 8 min. The effects of some key parameters such as adsorbent dosage, initial dye concentration and initial pH on dye adsorption were investigated in detail. The equilibrium adsorption data were better fitted by the Langmuir isotherm. The adsorption kinetics was well modelled using a pseudo‐second‐order model. Also, the inorganic–organic hybrid yolk–shell microspheres could be easily separated from the reaction system and reused up to four times without any change in structure or adsorption ability. The stability and robustness of the adsorbent were confirmed using various techniques.
Preventive maintenance for homogeneous and heterogeneous systems
Authors: Finkelstein Maxim , Levitin Gregory 
Published: December 2018

AbstractWe consider optimal preventive maintenance for homogeneous and heterogeneous systems with major (critical) and minor (noncritical) failures. A major failure results in a replacement of a failed system, whereas minor failures can be minimally instantaneously repaired. Distinct from the homogeneous case, where the process of minimal repairs is the Poisson process, the process of minimal repairs in the heterogeneous case is the mixed Poisson process that does not possess the memoryless property. This enables considering the number of minimal repairs as the decision parameter for the corresponding optimal preventive maintenance policy. The proposed approach is theoretically justified, and the detailed illustrative numerical examples are presented.
Das Museum ist nicht das Ende

Published: December 2018

AbstractIm Kontext denkmalpflegerischen Umgangs mit historischen Bauwerken stellen Freilichtmuseen einen Sonderfall dar. Die Umsetzung eines Baudenkmals in das Museum ist dabei in mehrfacher Hinsicht ein gravierender Eingriff. Der Transfer kann bspw. mit deutlich veränderten äußeren Beanspruchungen des Bauwerks einhergehen, etwa veränderten Schneelasten in dem Fall einer Umsetzung von einem Originalstandort im Flachland in ein höher gelegenes Museum. Wird beim Wiederaufbau die Ausrichtung des Bauwerks verändert, können bisher geschützte Fassadenabschnitte verstärkt der Witterung ausgesetzt sein. Ebenso bedingt die Museumsnutzung üblicherweise erheblich veränderte Ansätze für die auf das Binnengefüge anzusetzenden Verkehrslasten.Diese Aspekte wurden in der Gründungsphase zahlreicher Museen fallweise nicht berücksichtigt. Die inzwischen erforderliche Baupflege und Instandsetzung an den musealisierten Gebäuden erfordert daher für diese Objekte eine statisch‐konstruktive Neubewertung bis hin zur Revision einzelner, beim Wiederaufbau getroffener Entscheidungen. Notwendige Ertüchtigungsmaßnahmen unterliegen im Kontext eines Freilichtmuseums besonderen Anforderungen und müssen sich in bestehende Ausstellungskonzepte einfügen.Die besonderen Herausforderungen bei der Instandsetzung musealisierter Baudenkmäler werden anhand von zwei Fallbeispielen dargestellt.

Published: December 2018

AbstractIn this study, we translated and localized the Adult Decision‐making Competence scale (A‐DMC) and tested its reliability and validity with large samples. Results show the Chinese A‐DMC has relatively good reliability (Cronbach's alpha above 0.6 and test–retest reliability coefficients ranging from 0.44 to 0.78 on all subscales), comparable with the original version. Regarding validity, results of exploratory factor analysis and confirmatory factor analysis support the one‐factor model, indicating the A‐DMC has good internal consistency and construct validity. A‐DMC scores correlated positively with cognitive ability, constructive decision‐making styles, and good decision outcomes. Additionally, individuals with higher A‐DMC scores were found to perform better on the Cambridge gambling task and Iowa gambling task. These results confirm the validity of the Chinese version of the A‐DMC, which is suitable for measuring decision‐making competence in Chinese adults.
The convenient use of fluorescamine for spectrofluorimetric determination of midodrine hydrochloride in pure form and its tablets formulation: Application to content uniformity testing
Authors: Omar Mahmoud A. , Nagy Dalia M. , Halim Monica E. 
Published: December 2018

AbstractA novel sensitive and simple spectrofluorimetric method was developed then validated for determination of midodrine in both its authentic pure form and its tablets. This method is based on the reaction between midodrine's aliphatic primary amine moiety with fluorescamine reagent, using borate buffer at pH 7.8 and yielding a highly fluorescent product whose fluorescence intensity was measured at 462 nm after excitation at 388 nm. This method represents the first attempt for determination of midodrine spectrofluorimetrically. A calibration curve was constructed showing that the linear range was 0.2–3.0 μg/ml. The limit of detection and limit of quantitation values were 0.06 and 0.19 μg/ml respectively. The correlation coefficient (r) and the determination coefficient (r2) values were 0.9992 and 0.9984 respectively. The proposed method was validated according to ICH guidelines and successfully applied for determination of midodrine in its tablets with an overall % recovery of 99.56 ± 0.95. Finally, the presented method was adapted to study the content uniformity test according to United States Pharmacopeia guidelines.

Published: December 2018

AbstractSince independence, the political and planning processes in Ghana have evolved to reflect modern development dynamics. The discovery of oil in commercial quantities was yet another opportunity to transform the country through consolidated development plans and fast track the rate of inclusive development. The recent development framework, Ghana Shared Growth and Development Agenda (GSGDA I AND II) coincided with the initial stages of oil production.This paper seeks to: (i) ascertain the extent to which the revenue accruing from oil production has been used to boost human and infrastructural development; (ii) the contribution of oil revenue in closing funding gap present in the Ghana Shared Growth and Development Agenda (GSGDA I and II), and (iii) the extent to which expenditure from oil revenues were in line with the GGSGDA (I and II) 2010–2017. Regarding the first objective, the paper finds that oil investment was significant in the rail (72%) and housing (75%) sectors; medium in the road sector (17.6%) but poor in water (3%), ports development (0%) and educational (2%) sectors. Overall, the average contribution to core infrastructural development is found to be around 8%. Regarding the second objective, the paper finds that the contribution of oil revenue to bridging the funding gap in critical infrastructure is only 6.7%. Concerning the third objective, the research finds some mismatch between the use of oil revenue and the objectives of the GSGDA (I and II).The study therefore, recommends fiscal discipline, investment guidelines, proper budget execution, and prudent spending of oil revenues.
Exploratory study of international Corporate Social Responsibility initiatives of Indian firms
Authors: Bhattacharyya Som Sekhar 
Published: December 2018

AbstractInternationalization of business has become an emergent reality of emerging economy firms like from China and India. Through internationalization initiatives, firms expand its product market scope beyond domestic boundaries. Sociological theory of the firm posits that firms are embedded in society. Given the tenets of stakeholder theory, a firm has to address stakeholder issues even in the context of foreign countries post international expansion. In this research, the author conducted in‐depth interviews of 34 Indian CSR managers who have been involved in international CSR operations. The data were thematic, intensity, and relational content analyzed for insights. Findings related to both international CSR planning and implementation. The key findings indicated that Indian firms were more inclined to replicate in foreign contexts their CSR activities, which were being carried out domestically. Most international CSR decisions were planned and administered from Indian home CSR office. The nature of resources and capabilities that Indian firms deployed in foreign countries were mostly of Indian origin. Further, the defining processes involved in the management of international CSR were majorly designed by Indian home CSR office.
