The Presence of the Past: Imagination and Affect in the Museu do Oriente, Portugal
Authors: Peralta Elsa 
Published: May 2015

AbstractPortugal was the first and the most enduring of all European colonial empires, beginning in the fifteenth century with the establishment of a commercial domain in the East and lasting until 1974, when the fall of the dictatorship in Portugal paved the way for decolonization in the African colonies. Despite the formal end of the empire, a national imperialistic representation of the history of the country persists, immune to postcolonial critique and widely disseminated through school curricula, public discourses, and propaganda. The period known as the “Eastern Empire” came to capture the Portuguese collective imagination as the golden age of Portuguese history, embodying a self‐representation of Portugal – which remains until today – as a country of “Discoveries” rather than as a colonizing center. This chapter argues that the resilience of the established view of Portugal's imperial past is strongly dependent on a preferred mode of representation which is materially and visually based. It looks at the Museu do Oriente (Museum of the Orient) in Lisbon in an attempt to understand how the Portuguese national past is imagined and affected in the museum space through the presence of objects.
The Liquid Museum: New Institutional Ontologies for a Complex, Uncertain World
Authors: Cameron Fiona 
Published: May 2015

Abstract
In a world where rigid, fixed, and obsolete institutional structures and forms of analysis are increasingly problematic, new ontologies and knowledge practices are required that more clearly match the experience of contemporary circumstances. In this chapter I ontologically refashion the museum's agency as an institutional form and as a series of practices as liquid, mobile, and relational, and as heterogeneous assemblages made up of material and expressive forms enmeshed in diverse collectives comprising many human and nonhuman elements. As an assemblage, the liquid museum and its components are mobile, cohere with others, territorialize, and also disperse or deterritorialize according to certain conditions and events. Change, therefore, becomes a process, both intended and unintended, in which agency is rethought in terms of relational resources and institutional capacities. By rethinking the museum in these terms, we better equip institutions ontologically and practically to engage with hot topics of societal relevance and importance such as environmental change.
Preserving/Shaping/Creating: Museums and Public Memory in a Time of Loss
Authors: Gardner James B. 
Published: May 2015

AbstractScholars in museum studies, cultural anthropology, public history, and related fields have produced an impressive body of theoretical work exploring memory, memorialization, and museums. At the same time, from the Vietnam Veterans Memorial Wall to the Oklahoma City National Memorial and Museum to September 11 exhibitions and programs, museums have gained important practical experience on the ground, in negotiation with the public. In other words, museums are where theory is tested – it is real life, where stakeholders with different agendas come together to negotiate history, to create public memory. While harboring deep reservations about taking on memorial roles that are seen as inimical to museum responsibilities, curators and historians have had to address public expectations that we play a public commemorative role, that we step outside our museological comfort zones. This was particularly the case in collecting and interpreting September 11 at the Smithsonian's National Museum of American History, a moment when deep emotion often outweighed cultural and historical significance. Indeed the scale of the trauma, the level of collective grief and anger, and the often uncritical patriotism that followed September 11 shaped the documentation, preservation, and interpretation of the day and its aftermath. Drawing on that experience, this chapter focuses on the tension between public memorialization and the role of museums, between memorializing a moment and collecting and interpreting it, exploring how challenges to authority from stakeholders and the public are reshaping museum theory and practice.
Visible and Invisible Institutions: Cinema in the French Art Museum
Authors: Chamarette Jenny 
Published: May 2015

In this chapter, I argue the case that film, and cinema more broadly, have produced metaphorical and literal shifts of focus and frame within the museum context. The chapter initially discusses the multilayered ways in which film, as a representational medium and as an exhibited object, interacts with its political and sociocultural counterpart: the institution of cinema. I then argue that these focal shifts in the treatment of film in the museum, and the treatment of museums on film, potentially eliminate some aspects of the museum from cinema's perceptual field, while highlighting others, operating as a counterdiscourse to the prime concerns of museums at a given moment in time. These aspects are also subject to, and affected by changes in, the tangible materiality of cinema as an object, an experience, an exhibition space, and a cultural institution. Rather than imagining film as a “medium” in the technological or communicative sense, the chapter examines the politics of film as a mediator, negotiator, or indeed critic of museum spaces and museum politics. The “visible” and “invisible” institutions in the title of the chapter refer to these shifts in focus and frame that draw attention toward – or away from – the political and cultural contingency of film in the museum space.Cinema's historical and contemporary privileged position in French cultural heritage suggests that thinking about French museums specifically informs an understanding of the moving image's conceptual and spatial shift away from “cinema” as such, toward a broader conception of the medium. Cinema as we like to think about it has long since left the auditorium and found itself transmitted across multiple screen media technologies, from the handheld mobile device, to digital streaming, to large‐scale screening on tower blocks: such devices have inevitably been adopted by museums as modes of education, interpretation, and outreach. Increasingly, cinema, as a mutable cultural institution that defies visible definition, has made a shift into the museum – a sociocultural institution which often courts both physical presence and virtual existence, in add‐on digital apps, screen‐based interpretation, and online exhibition spaces. Consequently, the case studies of this chapter are situated within a French cultural context which offers concrete examples of the complex relationships between cinema and the museum. In doing so, the chapter interrogates the complex political, curatorial, and broader sociocultural concerns of the institutionalized housing of film within the museum, both as a public space and as a political institution.
Ambulatory Assessment: Methods for Studying Everyday Life
Authors: Conner Tamlin S. , Mehl Matthias R. 
Published: May 2015

AbstractAmbulatory assessment is a class of methods that use mobile technology to understand people's biopsychosocial processes in natural settings, in real time, and on repeated occasions. In this essay, we discuss the rationale for ambulatory assessment including the benefits of measuring people in the real world (greater ecological validity, better understanding of people in contexts), in real time (avoidance of memory bias, greater sensitivity for capturing change), and over time (capturing within‐person patterns and temporal trends). Then, we review the latest ambulatory assessment techniques for measuring experiences, behaviors, and physiology in daily life. Experiences such as emotions, physical pain, and daily stressors can be tracked using daily diaries and smartphone‐based experience sampling. Behaviors such as activity, movement, location, and natural language use can be tracked using accelerometers, portable actigraphs, global positioning system (GPS) coordinates, and the electronically activated recorder (EAR). Physiological processes such as heart rate, blood pressure, and electrodermal activity can be measured using an array of ambulatory biosensors. Ambulatory assessment will continue to be revolutionized by smartphones, which are becoming integrated seamlessly into people's lives. Emerging trends include social sensing applications that make inferences about users' psychological processes based on multi‐channel information collected from smartphones, emergence of “big data collection” whereby ambulatory assessment data is gathereden massefrom large populations, and the growing field of mobile health. These trends raise questions around the protection of participants' privacy and the synthesis of immense amounts of digital data. Ultimately, these developments will narrow the separation between science and everyday life as ambulatory assessment becomes an integrated part of people's mobile lives.
Copper‐Catalyzed Regio‐ and Stereoselective Ring‐Opening of Cyclic Sulfamidates with Grignard Reagents assisted by Lithium Chloride

Published: May 2015

AbstractCopper‐catalyzed ring‐opening reactions of cyclic 1,2‐sulfamidates with a wide range of Grignard reagents have been investigated. The use of lithium chloride as an additive is essential to activate CO bond cleavage. The reaction represents highly regio‐ and stereoselective, and thus allows for efficient synthesis of enantioenriched α‐branched benzylamine derivatives. Furthermore, we demonstrated that the products are potential to be used as building blocks for the preparation of wide range of nitrogen‐containing heterocycles.magnified image
Biocatalysis of Cycloastragenol by Syncephalastrum racemosum and Alternaria alternata to Discover Anti‐Aging Derivatives

Published: May 2015

AbstractCycloastragenol is a cycloartane‐type triterpenoid with significant telomerase‐activating activities. In this paper, the biocatalysis of cycloastragenol by two strains of filamentous fungi, namely Syncephalastrum racemosum AS 3.264 and Alternaria alternata AS 3.4578, was investigated. Scaled‐up biotransformation reactions yielded 27 metabolites. Their structures were established on the basis of extensive NMR and HR‐ESI‐MS data analyses, and 18 of them are new compounds. The two fungal strains exhibited distinct biocatalytic features. S. racemosum could catalyze ring expansion and epoxidation reactions to form 3β,10β‐epoxy‐ or 6α,19α‐epoxy‐9,10‐seco‐cycloartane structures, whereas A. alternata preferred to catalyze acetylation reactions, especially at 3‐OH, 6‐OH and 19‐OH. These regio‐ and stereoselective reactions are difficult to achieve by chemical means, but could be realized under mild conditions by biocatalysis. Furthermore, we found that some acetylated derivatives at 50 μM could significantly extend the lifespan of Caenorhabditis elegans from 16.93±0.70 d of the control group to 20.01±0.75 d (P<0.01), versus 18.54±0.67 d for cycloastragenol. These biotransformed derivatives of cycloastragenol could be potential anti‐aging agents.magnified image
Enzyme Module Systems for the Synthesis of Uridine 5′‐Diphospho‐α‐D‐glucuronic Acid and Non‐Sulfated Human Natural Killer Cell‐1 (HNK‐1) Epitope
Authors: Engels Leonie , Henze Manja , Hummel Werner , Elling Lothar 
Published: May 2015

AbstractTailor‐made strategies for the stereo‐ and regioselective multi‐step enzymatic synthesis of glycoconjugates require well characterized glycosyltransferases and carbohydrate modifying enzymes. We here report on a novel enzyme cascade for the synthesis of uridine 5′‐diphospho‐α‐D‐glucuronic acid (UDP‐GlcA) and the non‐sulfated human natural killer cell‐1 (HNK‐1) epitope including in situ regeneration of UDP‐GlcA and the cofactor nicotinamide adenine dinucleotide NAD+ by the combination of four enzymes in one‐pot. In the first enzyme module sucrose synthase 1 (SuSy1) is used to produce uridine 5′‐diphospho‐α‐D‐glucose (UDP‐Glc) from sucrose and uridine 5′‐diphosphate (UDP). The combination with UDP‐Glc dehydrogenase in the second enzyme module leads to the synthesis of UDP‐GlcA with concomitant in situ regeneration of the cofactor NAD+ by nicotinamide adenine dinucleotide hydride (NADH)‐oxidase. In the third enzyme module the mammalian glucuronyltransferase GlcAT‐P catalyzes the synthesis of the non‐sulfated HNK‐1 epitope by regioselective transfer of GlcA onto N‐acetyllactosamine type 2 (LacNAc type 2). We present a comprehensive study on substrate kinetics, substrate specificities, variation and relation of enzyme activities as well as cross inhibition of intermediate products. With optimized reaction conditions we obtain superior product yields with streamlined synthesis costs for the expensive nucleotide sugar UDP‐GlcA and cofactor NAD+.magnified image

Published: May 2015

AbstractAn asymmetric bio‐ and organocatalytic cascade one‐pot reaction for the α‐arylation of aldehydes is presented. 1,4‐Dihydroxybenzene and its derivatives are oxidized to quinones by laccase and aerial oxygen. This catalytic process has been efficiently coupled to asymmetric enamine organocatalysis, affording 3‐substituted 2,3‐dihydrobenzofuran‐2,5‐diols in moderate to good yield and moderate to excellent enantioselectivity.magnified image
A New Method for Getting Rational Approximation for Fractional Order Differintegrals
Authors: Dhabale Ashwin S. , Dive Rutuja , Aware Mohan V. , Das Shantanu 
Published: May 2015

AbstractIn this paper a new algorithm is presented to calculate the poles and zeros to approximate a fractional order (FO) differintegral (s±α,α∈(0,1)) by a rational function on a finite frequency band ω∈(ωl,ωh). The constant phase property of the FO differintegral is the basis for development of the algorithm. Interlacing of real poles and zeros is used to achieve the constant phase. The calculations are done using the asymptotic Bode phase plot. A brief investigation is made to get a good approximation for the Bode phase plot. Two design parameters are introduced to keep the average phase close to the desired phase angle and to keep the error within the allowed bounds. A study is done to empirically understand the relationship between the error and the design parameters. The results thus obtained help in the further calculations. The algorithm is computationally simple and inexpensive, and gives a fairly good approximation of fractance frequency response on the specified frequency band.

ABSTRACTAntibody detection in autoimmune disorders, such as multiple sclerosis (MS) and Rett syndrome (RTT) can be achieved more efficiently using synthetic peptides. The previously developed synthetic antigenic probe CSF114(Glc), a type I′ β‐turn N‐glucosylated peptide structure, is able to recognize antibodies in MS and RTT patients’ sera as a sign of immune system derangement. We report herein the design, synthesis, conformational analysis, and immunological evaluation of a collection of glycopeptide analogs of CSF114(Glc) to characterize the specific role of secondary structures in MS and RTT antibody recognition. Therefore, we synthesized a series of linear and cyclic short glucosylated sequences, mimicking different β‐turn conformations, which were evaluated in inhibition enzyme‐linked immunosorbent assays (ELISA). Calculated IC50 ranking analysis allowed the selection of the candidate octapeptide containing two (S)−2‐amino‐4‐pentynoic acid (L‐Pra) residues Ac‐Pra‐RRN(Glc)GHT‐Pra‐NH2, with an IC50 in the nanomolar range. This peptide was adequately modified for solid‐phase ELISA (SP‐ELISA) and surface plasmon resonance (SPR) experiments. Pra‐RRN(Glc)GHT‐Pra‐NH2 peptide was modified with an alkyl chain linked to the N‐terminus, favoring immobilization on solid phase in SP‐ELISA and differentiating IgG antibody recognition between patients and healthy blood donors with a high specificity. However, this peptide displayed a loss in IgM specificity and sensitivity. Moreover, an analog was obtained after modification of the octapeptide candidate Ac‐Pra‐RRN(Glc)GHT‐Pra‐NH2 to favor immobilization on SPR sensor chips. SPR technology allowed us to determine its affinity (KD = 16.4 nM), 2.3 times lower than the affinity of the original glucopeptide CSF114(Glc) (KD = 7.1 nM). © 2015 Wiley Periodicals, Inc.

Disabled Children and the Child Protection System: A Cause for Concern
Authors: Taylor Julie , Stalker Kirsten , Stewart Alasdair 
Published: May 2015

Disabled children are more likely to be abused than their non‐disabled peers. Despite this heightened risk, the abuse of disabled children often goes undetected and under‐reported. This qualitative study investigated the specific issues faced by practitioners in Scotland in supporting disabled children at risk of significant harm. Interviews were held with participants from six local authority areas and across five different services, and five focus groups with child protection committees (total 61 participants). There were positive messages about putting the child at the very heart of child protection assessment and intervention, regardless of any impairment that a child may have. However, there was also concern that practice was at times parent‐centred. Some participants appeared to be ‘muddling through’ in practice and many practitioners lacked confidence when working with disabled children. Data from this study suggest that thresholds for disabled children may be higher than for non‐disabled children. Participants reported high levels of interagency working and saw this as inherently positive, although they recognised some failings and tensions. There is widespread commitment across the child protection system to putting the child at the centre. However, getting it right for every child does not mean treating every child the same.

There is significant evidence that disabled children are at greater risk of abuse than their non‐disabled peers.
Practitioners are sometimes so concerned with keeping the child at the centre they may fail to account for the added complexities and vulnerabilities that impairment can bring.
Equality does not mean treating every child the same.

Studies on permeability of sisal fibre mat during thermoset resin filling in vacuum infusion process
Authors: Subbiah Rajkumar , Tjong Jimmy , Nayak Sanjay K. , Sain Mohini 
Published: May 2015

AbstractThe focus of this study is contemplating the resin flow behaviour (dictating permeability) in a sisal based natural fibre mat compared to a glass fibre mat. This mainly deploys fibre reinforced plastics subjected to a vacuum infusion process. The outcome of this research emphasizes the wetting mechanism and fibre network of sisal mats, which significantly reduces the flow characteristics. In addition, it is observed that the swelling phenomenon had an insignificant or minimal influence on the permeability of the sisal fibre mat. However, employment of bio‐based resin provides a considerable change in the swelling phenomenon. Hence, this factor is important to consider in permeability studies to attain higher accuracy.
Solution‐Processed Ultrathin Aluminosilicate Nanotube–Poly(vinyl alcohol) Composite Membranes with Partial Alignment of Nanotubes

Published: May 2015

AbstractThe fabrication of ultrathin (300 nm) aluminosilicate nanotube–poly(vinyl alcohol) composite membranes with partial vertical alignment of the nanotubes (up to 33 %), by solution‐casting methods on porous polymeric substrates, is reported. A high loading (up to 60 vol %) of nanotubes is achieved. A comprehensive microstructural characterization of the membranes is performed by a combination of SEM, TEM, grazing‐incidence wide‐angle X‐ray scattering measurements, and simulations. This investigation shows that the nanotubes are individually dispersed and partially aligned in the polymeric matrix by the use of appropriate matrix and substrate materials. Permeation measurements of gas probe molecules (CO2 and CH4) on two different types of membranes, one containing bare nanotubes and the other containing amine‐functionalized nanotubes, also support the proposed microstructure of the thin nanocomposite membranes.
Amino Acid‐Dependent Host–Guest Interaction: Polyglycerol Dendrimer of Generation 3 Encapsulates Amino Acids Bearing Two Amino Groups
Authors: Ooya Tooru , Lee Haejoo 
Published: May 2015

AbstractA polyglycerol dendrimer (PGD), which is known as a biocompatible compound, was demonstrated as a host molecule for amino acids. PGD of generation 3 (PGD‐G3) was found to interact with basic α‐amino acids such as l‐arginine (Arg) and l‐lysine (Lys) in water. The results of isothermal titration calorimetry, 1H NMR, and 1H‐1H NOESY NMR measurements revealed that two basic groups in α‐amino acids were essential for encapsulation by PGD‐G3. An increase in the pKa value of the amino acid side chains (Arg>Lys>His>Glu) increased the binding constant, thus suggesting that the basicity of α‐amino acids is an important factor to interact with ether oxygen of PGD‐G3. The results demonstrate the utility of PGD‐G3 toward incorporation of α‐amino acids, peptides, and basic proteins in water.
Frame and carrier frequency synchronization algorithm for wireless body area network
Authors: Kim Byung‐Kyu , Song Hyoung‐Kyu , Seo Sung‐Il , You Young‐Hwan 
Published: May 2015

SummaryA wireless body area network (WBAN) is a radio‐frequency‐based wireless communication technology that consists of a number of different sensor and actuator nodes interconnected with a body gateway. Considering the constrained resources in WBAN devices, simple and noise‐robust synchronization algorithms are required. Frame synchronization and frequency offset estimation are extremely important in the design of a robust WBAN receiver. In this paper, a detection strategy such as frame synchronization and frequency estimation is described in the WBAN system, which can improve the receiver performance. In doing so, algorithms are designed or chosen for the frame detection, carrier frequency offset synchronization, and joint fine‐time and phase‐offset estimation by exploiting the spike‐like property of the physical layer convergence protocol preamble and the frame structure in the WBAN system. The performance of the WBAN synchronization receiver is verified by computer simulation. Copyright © 2015 John Wiley & Sons, Ltd.
