The Thought and Feel of Virtuous Wifehood: Recovering Emotion in the Legend of Good Women
Authors: Shutters Lynn 
Published: January 2017

Abstract
Despite studies arguing for an ironic or sincere depiction of loving women in the Legend of Good Women, scholars have not yet sufficiently examined the cognitive, affective, and performative processes that constitute love in either the poem itself or its late medieval cultural context. Adopting formalist methodologies, this article identifies Chaucer's Legend as an important document in the recovery of late medieval formulations of marital affection, particularly as they relate to women. Chaucer's Legend suggests that marital affection was a contentious emotion in the later Middle Ages subject to multiple, competing formulations. Because marital love was an emotion in progress, the Legend presents love as both an ethical injunction and an epistemological quandary in which the stakes for women are especially high.
United Service in Divisive Times: The Pittsburgh Council of Churches, 1916–1929

Published: January 2017

ABSTRACT
Despite the disruption of the Great Steel Strike of 1919 and the fundamentalist-modernist controversy of the 1920s, the Pittsburgh Council of Churches managed to hold together a fragile coalition for the cause of social betterment in the Steel City. Their noteworthy service record reveals a Protestant establishment eager to appear strong in the face of mounting criticism of indifference as well as a sincere desire to do good.

Background: In recent years, a worldwide dissemination of CTX-M beta-lactamase-type in Escherichia coli strains isolates from community-acquired urinary tract infections (CA-UTI) has been observed. However little is known on the prevalence and risk factors of this global threat in developing countries. Objective: The aim of this study was to study the prevalence and risk factors for CA-UTI in Yaoundé, Cameroon. Methods: Eighty six patients with urinary E.coli infection recruited from 10 health structures in the town of Yaoundé, Cameroon. After taking the first urine, faeces were collected from the patients for the study of the intestinal flora. The sample collection of faeces was done on a selected gel of enterobacteria resistant to third generation of cephalosporin. The molecular typing of extended-spectrum -lactamase (ESBL) was carried out. Results: Eighty-six strains of E. coli from 86 patients were included. We found that 39 (45.3%) strains produced an extendedspectrum beta-lactamase. Among risk factors, previous use of antibiotic and the dry season were associated with the presence of an ESBL-producing strain in the urine. All ESBL were identified as CTX-M. The production of CTX-M was found to be significantly associated with resistance to fluoroquinolones, aminoglycosides and to the association of trimethoprim-sulfamethazole. Conclusions: The prevalence of CTX-M ESBL in Yaoundé, Cameroon, provides new evidence on the global dissemination of CTX-M and the extent of this phenomenon in developing countries.
Inappropriate admissions or inadequate discharges of frail elderly: Competing program theories and implementation challenges in an intermediate care intervention

Published: January 2017

Intermediate care interventions are increasingly being implemented in the health services to avoid hospitalizing elderly frail patients with complex medical issues, often referred to as inappropriate or unwarranted admissions. This paper presents a theory-based stakeholder evaluation of an intervention involving hospitals, community care and general practitioners (GPs) in a Danish region with the overall objective to reduce the number of (inappropriate) hospital admissions for the frail elderly of 65 years or older. In a controlled study design elderly acutely ill patients were randomized to care and treatment either by a district nursing team or in an emergency department (ED) – both interventions with a 48-hour time limit. The district nursing teams were given access to various telemedicine solutions. In the programme theory analysis the stakeholders’ normative theories, situation theories and causal theories were studied. Competing programme theories and barriers and facilitators were identified. Data were collected in interviews with stakeholders (managers, nurses, hospital physicians and GPs) and from the literature. The intervention included a regional hospital, four municipalities and 166 GPs servicing a mixed urban and rural region in Denmark. Four district nursing teams, eight GPs, three hospital physicians and two project managers were interviewed between January and March 2015. The stakeholder’s programme theories were both concordant and competing; the GPs in particular were sceptical of the purported objective of reducing the number of inappropriate hospital admissions; they would rather see a reduction in the number of inappropriate hospital discharges. Our results indicate a compromised implementation process.
Sensitivity of the quasi‐biennial oscillation simulated in WACCM to the phase speed spectrum and the settings in an inertial gravity wave parameterization

Published: January 2017

AbstractThe application of inertial gravity wave parameterization has allowed for the spontaneous generation of quasi‐biennial oscillation (QBO) in the Whole Atmosphere Community Climate Model (WACCM), although there is some mismatch when comparing with observations. The parameterization is based on Lindzen's linear saturation theory, modified to describe inertia‐gravity waves (IGW) by considering the Coriolis effect. In this work, we improve the parameterization by importing a more realistic IGW phase speed spectrum that exhibits a double peak Gaussian distribution calculated from tropical radiosonde observations. A series of numeric simulations are performed to test the sensitivity of QBO‐like oscillation features to the phase speed spectrum and the settings of parameterized IGW. All these simulations are capable of generating equatorial wind oscillations in the stratosphere based on standard spatial resolution settings. Central phase speeds of the “double‐Gaussian parameterization” affect QBO magnitudes and periods, and the momentum flux of IGW determines the acceleration rate of zonal wind. Furthermore, stronger IGW forcing can lead to a propagation of the QBO‐like oscillation to lower altitude. The intermittency factor of the parameterization also prominently affects the QBO period. Stratospheric QBO‐like oscillation with obvious improvements is generated using the new IGW parameterization in a long‐time simulation.
Bioarchaeology in the ancientNearEast: Challenges and future directions for the southern Levant
Authors: Sheridan Susan Guise 
Published: January 2017

AbstractThe synthesis of biological anthropology, archaeology, and social theory provides a bioarchaeological model to reconstruct nuanced aspects of demography, diet, disease, death, daily activities, and biodistance, even in the absence of discrete burials. Numerous skeletal assemblages in the southern Levant are composed of mixed and fragmented bones resulting from generational use of cemeteries, mass burial, and additional communal burial practices. Others become commingled due to taphonomic processes such as flooding, geological events, or human mediated mechanisms like looting, improper excavation, and poor curation. Such collections require one to ask broader questions of human adaptability, exercise a holistic approach, use broad demographic categories, and remain cognizant of the limitations posed by fragmentation. Expanded research questions and ethical considerations, the use of centralized databases and understudied collections, as well as the application of social media, citizen science, and crowd sourcing provide new tools for bioarchaeological analyses of the many commingled ancient Near Eastern collections in the southern Levant.
Output Feedback Robust MPC Based on Off‐line Observer for LPV Systems via Quadratic Boundedness
Authors: Ping Xubin 
Published: January 2017

AbstractFor the linear parameter varying (LPV) system with available scheduling parameter and bounded disturbance, a synthesis approach to output feedback robust model predictive control (OFRMPC) is considered. By applying the technique of quadratic boundedness, the on‐line method with the refreshment of the bounds of estimation error guarantees the robust stability of the augmented closed‐loop system. For reducing the on‐line computational burden, the look‐up table that stores off‐line optimized control laws and the corresponding regions of attraction is constructed. The on‐line control law is searched based on the bounds of estimation error set and the region of attraction with the closest containment of the real‐time estimated state. A continuous stirred tank reactor (CSTR) model is given to illustrate the effectiveness of the method.
Absorption Spectroelectrochemistry on Mixed Perylenediimide‐Based Self‐Assembled Monolayers: Non‐Linear Dependence of Absorbance versus Surface Coverage

Published: January 2017

AbstractThe study of mixed self‐assembled monolayers of perylenediimide and hexanethiol by cyclic voltammetry and absorption spectroelectrochemistry shows a non‐linearity of absorbance maxima as a function of the surface coverage. This surprising result could be supported by an increase in the average tilt angle at low coverage, suggesting that the dilution of redox species through an alkanethiol would induce a change of the orientation of immobilized chromophores and, therefore, a modification of the optical properties of the monolayer.

Published: January 2017

AbstractTo date, a plethora of λ3‐P nitrogen‐containing compounds is known. A large number of them are used as ligands in coordination chemistry and homogeneous catalysis. PN‐containing compounds tend to build up cyclic moieties, which have received less attention in regard to their application as ligands in transition metal chemistry. Hence, different dehalogenation reactions of N,N‐bis{chloro(aryl)‐phosphino}‐amines have been developed to synthesize different P‐N‐P containing cyclic compounds. Their coordination behavior to group VI transition metal carbonyls was explored.
Low‐Energy Catalytic Electrolysis for Simultaneous Hydrogen Evolution and Lignin Depolymerization

Published: January 2017

AbstractHere, a new proton‐exchange‐membrane electrolysis is presented, in which lignin was used as the hydrogen source at the anode for hydrogen production. Either polyoxometalate (POM) or FeCl3 was used as the catalyst and charge‐transfer agent at the anode. Over 90 % Faraday efficiency was achieved. In a thermal‐insulation reactor, the heat energy could be maintained at a very low level for continuous operation. Compared to the best alkaline–water electrolysis reported in literature, the electrical‐energy consumption could be 40 % lower with lignin electrolysis. At the anode, the Kraft lignin (KL) was oxidized to aromatic chemicals by POM or FeCl3, and reduced POM or Fe ions were regenerated during the electrolysis. Structure analysis of the residual KL indicated a reduction of the amount of hydroxyl groups and the cleavage of ether bonds. The results suggest that POM‐ or FeCl3‐mediated electrolysis can significantly reduce the electrolysis energy consumption in hydrogen production and, simultaneously, depolymerize lignin to low‐molecular‐weight value‐added aromatic chemicals.

Published: January 2017

AbstractIt has recently been shown that waste biomass can be converted into a wide range of functional materials, including those with desirable optical and electronic properties, offering the opportunity to find new uses for these renewable resources. Photovoltaics is one area in which finding the combination of abundant, low‐cost and non‐toxic materials with the necessary functionality can be challenging. In this paper the performance of carbon nanodots derived from a wide range of biomaterials obtained from different biomass sources as sensitisers for TiO2‐based nanostructured solar cells was compared; polysaccharides (chitosan and chitin), monosaccharide (d‐glucose), amino acids (l‐arginine and l‐cysteine) and raw lobster shells were used to produce carbon nanodots through hydrothermal carbonisation. The highest solar power conversion efficiency (PCE) of 0.36 % was obtained by using l‐arginine carbon nanodots as sensitisers, whereas lobster shells, as a model source of chitin from actual food waste, showed a PCE of 0.22 %. By comparing this wide range of materials, the performance of the solar cells was correlated with the materials characteristics by carefully investigating the structural and optical properties of each family of carbon nanodots, and it was shown that the combination of amine and carboxylic acid functionalisation is particularly beneficial for the solar‐cell performance.

Published: January 2017

AbstractAqueous biphasic systems were investigated for the production of formate–amine adducts by metal‐catalyzed CO2 hydrogenation, including typical scrubbing solutions as feedstocks. Different hydrophobic organic solvents and ionic liquids could be employed as the stationary phase for cis‐[Ru(dppm)2Cl2] (dppm=bis‐diphenylphosphinomethane) as prototypical catalyst without any modification or tagging of the complex. The amines were found to partition between the two phases depending on their structure, whereas the formate–amine adducts were nearly quantitatively extracted into the aqueous phase, providing a favorable phase behavior for the envisaged integrated reaction/separation sequence. The solvent pair of methyl isobutyl carbinol (MIBC) and water led to the most practical and productive system and repeated use of the catalyst phase was demonstrated. The highest single batch activity with a TOFav of approximately 35 000 h−1 and an initial TOF of approximately 180 000 h−1 was achieved in the presence of NEt3. Owing to higher stability, the highest productivities were obtained with methyl diethanolamine (Aminosol CST 115) and monoethanolamine (MEA), which are used in commercial scale CO2‐scrubbing processes. Saturated aqueous solutions (CO2 overpressure 5–10 bar) of MEA could be converted into the corresponding formate adducts with average turnover frequencies up to 14×103 h−1 with an overall yield of 70 % based on the amine, corresponding to a total turnover number of 150 000 over eleven recycling experiments. This opens the possibility for integrated approaches to carbon capture and utilization.

Published: January 2017

AbstractBackgroundThere is substantial variability in the prognosis of acute low back pain (LBP). The ability to identify the probability of individual patients recovering by key time points would be valuable in making informed decisions about the amount and type of treatment to provide. Predicting recovery based on presentation 1‐week after initially seeking care is clinically important and may be more accurate than predictions made at initial presentation. The aim of this study was to predict the probability of recovery at 1‐week, 1‐month and 3‐months after 1‐week review in patients who still have LBP 1‐week after initially seeking care.MethodsThe study sample comprised 1070 patients with acute LBP, with a pain score of ≥2 1‐week after initially seeking care. The primary outcome measure was days to recovery from pain. Ten potential prognostic factors were considered for inclusion in a multivariable Cox regression model.ResultsThe final model included duration of current episode, number of previous episodes, depressive symptoms, intensity of pain at 1‐week, and change in pain over the first week after seeking care. Depending on values of the predictor variables, the probability of recovery at 1‐week, 1‐month and 3‐months after 1‐week review ranged from 4% to 59%, 19% to 91% and 30% to 97%, respectively. The model had good discrimination (C = 0.758) and calibration.ConclusionsThis study found that a model based on five easily collected variables could predict the probability of recovery at key time points in people who still have LBP 1‐week after seeking care.SignificanceA clinical prediction model based on five easily collected variables was able to predict the likelihood of recovery from an episode of acute LBP at three key time points. The model had good discrimination (C = 0.758) and calibration.

Intraoperative detection of residual malignant cells at tumor margins following excision of primary tumors could help improving surgery and thus patients' outcome. The feasibility of the tumor antigens epidermal growth factor receptor (EGF‐R) and epithelial cell adhesion molecule (EpCAM) for antibody‐dependent confocal laser scanning endomicroscopy (CLE)‐mediated visualization of malignant cells was addressed. Both tumor antigens are highly and frequently expressed in the majority of carcinomas, including head and neck squamous cell carcinomas (HNSCC), and represent prognostic and therapeutic tumor target molecules. FITC‐conjugated EGF‐R‐ and EpCAM‐specific antibodies served as molecular tools for the detection of antigen‐positive cells using the CLE technology. Specificity of both antibodies and their ability to discriminate tumor from non‐tumor cells were assessed in vitro with human fibroblasts and PCI‐1 HNSCC cell lines, and ex vivo on primary HNSCC samples (n = 11) and healthy mucosa (n = 5). Antigen specificity of the used EpCAM‐specific antibody was superior to that of the EGF‐R‐specific antibody both in vitro and ex vivo (100% vs. 31.25%), and allowed visualization of cellular structures in CLE measurements. These results hold promise for possible future applications in humans.

Published: January 2017

It is an emerging focus to explore controlled release drug delivery systems for simultaneous cancer imaging and therapy. Herein, we synthesized a photothermal sensitive multifunctional nano‐liposome drug delivery system, with doxorubicin wrapped in the hydropholic layer as the therapeutical agent and cypate doped in the hydrophobic layer as the diagnostic agent. A series of in vitro and in vivo characterization demonstrated the stability of synthesized liposome, as the DL% was 9 ± 1.5 and the EE% was 82.7 ± 2.1. And the liposome achieved the functions of target‐delivery, enhanced photochemical internalized drug release, and simultaneous chemotherapy and thermal therapy, indicating that this multifunctional nano‐liposome is a promising drug delivery system for tumor diagnosis and targeting therapy.

Simultaneous multiplane imaging‐based localization encoded (SMILE) microscopy for super‐resolution volume imaging
Authors: Mondal Partha Pratim 
Published: January 2017

AbstractWe propose a widefield‐based rapid super‐resolution volume imaging technique. This technique requires encoding single molecules to their respective planes and subsequent identification of the locus of individual molecule (both in the focal plane and off‐focal planes). Experimentally, this is achieved by precise calibration of system PSF size and its natural spread in the off‐focal planes using sub‐diffraction fluorescent beads. The specimen plane touching the coverslip is chosen as the focal plane whereas planes far from coverslip (situated at large penetration depths) represent off‐focal planes. The identification and sorting of single molecules are carried out by setting multiple cut‐offs to the respective PSFs and a 3D super‐resolved volume image is reconstructed. SMILE microscopy technique eliminates the need for multiple z‐plane scanning, minimizes radiation‐dose and enables rapid super‐resolution volume imaging.
Assessment of biochar and hydrochar as minor to major constituents of growing media for containerized tomato production

Published: January 2017

AbstractBACKGROUNDChars are emerging materials as constituents of growth media. However, chars of different origin differ in their characteristics and more studies are needed to ratify them for such a role. The characteristics of coir mixed with 0%, 10%, 25%, 50%, 75%, and 100% (v/v) of two biochars, from forest waste (BCH‐FW) and from olive mill waste (BCH‐OMW), and one hydrochar, from forest waste (HYD‐FW), and their effects on growth, yield and fruit quality of two tomato cultivars (Gransol RZ and Cuarenteno) were assessed.RESULTSChars negatively affected plant growth and yield but not fruit quality. The effect was related to the char dose and was larger in HYD‐FW and BCH‐FW than in BCH‐OMW, despite the high salinity of the latter, and more acute in Cuarenteno than in Gransol RZ. The results were discussed on the basis of the large particle size of BCH‐FW, which could have caused low nutrient solution retention and, hence, reduced plant nutrient uptake, and the high water‐holding capacity, poor aeration and large CO2 emission of HYD‐FW, which could lead to root anoxia.CONCLUSIONBCH‐OMW can be used at high proportion in media for tomato cultivation. The use of BCH‐FW at a high proportion might be taken into consideration after adjusting particle size, yet this needs additional assays. HYD‐FW is inadequate for soilless containerized tomato cultivation. © 2017 Society of Chemical Industry
