Published: December 2017

AbstractThe production of commercialized Cu(In,Ga)(S,Se)2 (CIGS) photovoltaic absorber layers uses expensive H2Se gas with a high utility cost. To reduce the manufacturing cost of CIGS photovoltaic modules, a process technology capable of supplying Se vapor uniformly over a large area is required to replace H2Se. In this study, a nozzle‐free Se shower was implemented using a porous material to pass Se vapor while confining liquid Se, and the highly effective selenization of the CuInGa precursor was performed. The nozzle‐free Se‐shower vehicle could be mounted in a commercial rapid thermal process chamber. The chamber pressure and the temperatures of the shower module and substrate, which were controlled independently by the upper and lower heaters, respectively, were varied to control the amount of Se supplied during the entire selenization reaction in real time. In particular, the precursor should be soaked with a sufficient amount of Se at a relatively low substrate temperature of 300°C or less to obtain a good quality absorber. In addition, at a chamber pressure of 100 Torr during the soaking stage, the Ga content in the surface region of the absorber increased considerably with a concomitant improvement in the open‐circuit voltage. The highest performance obtained using this method was an open‐circuit voltage of 0.638 V, short‐circuit current density of 34 mA/cm2, fill factor of 67.2%, and an active area efficiency of 14.57%. This performance is very high compared with other CIGS solar cells manufactured by a 2‐step process using Se vapor.

AbstractSix new 3D lanthanide‐based organic frameworks with the formula of [Ln2(1,4‐BDC)2(ox)(H2O)4]⋅2H2O (Ln=Tb1, Dy2, Gd3) and [Ln2(1,4‐BDC)2(ox)(H2O)2] (Ln=Ho4, Er5, Yb6; 1,4‐H2BDC=1,4‐benzenedicarboxylate; H2ox=oxalate acid) were synthesized by hydrothermal method and characterized by elemental analysis, IR spectra, UV–vis spectra, powder X‐ray diffraction, and TG‐DTA method, wherein compounds1and4were structurally characterized. Compounds1–3had been found to be isostructural and crystallized in the monoclinic crystal system with space group ofP21/c possessing quasi‐square 1D channels wherein lattice water molecules were encapsulated, while the isostructural compounds4–6crystallized in triclinic system withP‐1 space group, while their triangular 1D channels are too small to encapsulate any solvent molecules. The significant lanthanide contraction effect is evident from the observed resulting structures of compounds1–6which were synthesized under the same reaction conditions. Compounds1and2exhibited characteristic emissions of Tb(III) and Dy(III) ions and the luminescent lifetime of compound1was found to be 0.54 ms.

AbstractWe synthesised aza‐12‐crown‐4 ether‐substituted naphthalene diimide (NDI‐12‐C‐4) and demonstrated its properties as an fluorescent and colorimetric sensor. The NDI‐12‐C‐4 uses the aza‐12‐crown‐4 moiety to bind Li+ ion selectively over larger monovalent cation such as Cs+, Na+ and K+. The sensor is chemically stable due to the crown‐ether, and the appended NDI fluorophore allows leads to optical changes exclusively for the monovalent Li+ ion. UV–vis absorption, fluorescence, cyclic voltammetry (CV), 1H NMR and naked eye‐detection clearly demonstrate selective, sensitive binding of Li+ ion with a detection limit of 5.0 μM. Importantly, reversible binding of Li+ by NDI‐12‐C‐4 was also observed upon addition of EDTA, after which the sensor could be recovered via simple centrifugation, indicating suitability for use in a biological sensor device.

Published: December 2017

AbstractA simple yet efficient one‐pot ultrasonication process for the green preparation of a silver–carbon nanotube (Ag‐CNT) ink, which was then used to fabricate conductive flexible thin films by a simple immersion process, is reported. A novel three‐dimensional (3D) porous, hierarchical Ag–MnOx–CNT nanocomposite was synthesized by electrodeposition of manganese oxide (MnOx) nanosheets composed of MnO2 and Mn3O4 onto the Ag–CNT films. The unique Ag–MnOx–CNT electrode showed a specific capacitance of 842 F/g at 1 A/g and excellent charge–discharge cycling stability, with a capacitance retention of 148% at 10 A/g and a Coulombic efficiency of ∼90% after 5000 cycles. The greatly enhanced capacitive performance is ascribed to the facile redox reactions, 3D porous framework, and use of Ag NPs. These impressive results suggest that this nanocomposite is a promising candidate for use in high‐performance flexible energy storage applications.
Characterization of Local Aromaticity in Polycyclic Conjugated Hydrocarbons Based on Anisotropy of π‐Electron Density
Authors: Firouzi Rohoullah , Shafie Hoda , Tohidnia Hassan 
Published: December 2017

AbstractIn recent contributions, it was demonstrated that the anisotropy of π‐electron density could be considered as a reliable descriptor to probe the aromaticity in a wide range of annulene and hetero‐monocyclic compounds. The electron density anisotropy on a plane can be simply measured by the ratio of two in‐plane Hessian eigenvalues associated with the eigenvectors lying in the plane. This descriptor is undirected and has a circular symmetry for aromatic rings, whereas it is directed and has an elliptical shape in antiaromatic cycles. This research takes a step forward towards the extension of this approach to polycyclic conjugated hydrocarbons. The obtained results show that the anisotropy of the π‐electron density works nicely for the assessment of local aromaticity in polycyclic compounds. This finding provides clear evidence to have a universally successful aromaticity descriptor based on the topological properties of one‐electron density distribution.
Performance feedback and middle managers’ divergent strategic behavior: The roles of social comparisons and organizational identification

Published: December 2017

Research Summary: What drives middle managers to search for new strategic initiatives and champion them to top management? This behavior—labeled divergent strategic behavior—spawns emergent strategies and thereby provides one of the essential ingredients of strategic renewal. We conceptualize divergent strategic behavior as a response to performance feedback. Data from 123 senior middle managers overseeing 21 multi‐country organizations (MCOs) of a Fortune 500 firm point to social performance comparisons rather than historical comparisons in driving divergent strategic behavior. Moreover, managers’ organizational identification affects whether they attend to organizational‐ or individual‐level feedback. These results contribute to research on performance aspirations and strategy process by providing a multilevel, multidimensional framework of performance aspirations in middle management driven strategic renewal.Managerial Summary: Middle managers are essential actors in strategic renewal. Their unique positions offer insights into operations alongside knowledge of strategy. In contrast to typical assessments of managerial performance with reference to a prior year, this research shows that performance comparisons relative to peers and other organizational units better motivate managers’ divergent strategic behavior. Our results also show that managers who identify with the firm are more attentive to organizational rather than individual performance discrepancies. Thus, our study unveils an important approach for organizations aiming to spark strategic renewal.
Evolving efficacy of managerial capital, contesting managerial practices, and the process of strategic renewal
Authors: Pratap Sankalp , Saha Biswatosh 
Published: December 2017

Research Summary: This article examines the adaptation process of a large manufacturer in the Indian steel industry faced with radical sociopolitical shifts in the external ecosystem. It uses the Bower‐Burgelman process model in combination with Bourdieu's praxis theory to explain the emergence of competing managerial initiatives and associated contests in the company's internal ecology of strategy‐making in terms of socially acquired dispositions. It illuminates process–practice pathways through which top management's resource allocation supported changes in the efficacy of the different forms of capital of the contesting managerial classes, thereby legitimizing the daily “doings” of the rising class and institutionalizing a (re)defined adaptive rule structure.Managerial Summary: How do managers’ early influences, including family upbringing and schooling, bear upon organization's renewal strategy? Our study finds that during discontinuities imposed by socioeconomic upheavals, when organizational performance flounders, managerial initiatives are driven by deepest dispositions derived from early age socialization. Competing managerial fractions jostle to impose practices favorable to their longstanding preferences by putting their weight behind preferred product‐market choices and seeking appropriate changes in the ineffective internal rule structure. Administration's challenge lies in leveraging internal contests to iteratively allocate resources in search of winning dispositions and configurations aligned with evolving social relations in the external environment. Internal availability of managerial groups from diverse social origins is crucial for the administration to reclaim organizational advantage by arbitrating between contesting practices and practitioner fortunes.

Published: December 2017

The increasing complexity of the power grid and the continuous integration of volatile renewable energy systems on all aspects of it have made more precise forecasts of both energy supply and demand necessary for the future Smart Grid. Yet, the ever increasing volume of tools and services makes it difficult for users (e.g., energy utility companies) and researchers to obtain even a general sense of what each tool or service offers. The present contribution provides an overview and categorization of several energy‐related forecasting tools and services (specifically for load and volatile renewable power), as well as general information regarding principles of time series, load, and volatile renewable power forecasting.

AbstractObjectivesWe aimed to assess possible risk factors related to difficult intubation in patients undergoing thyroid surgery.MethodsWe prospectively collected data of 200 patients scheduled for thyroid surgery. Clinical risk factors were defined as: Mallampati score, interincisor gap, thyromental distance, sternomental distance, range of neck motion, body mass index, neck circumference, goiter, the presence of radiological findings suggesting compression and thyroid weight. All evaluations were performed with Macintosh assessed for Cormack and Lehane (CL) classification and modified intubation difficulty scale (MIDS).ResultsIt was observed that the proportion of patients with a thyroid weight ≥40 g, goiter, a Macintosh CL score = 3–4 and the mean neck circumference were significantly higher in the group with a MIDS score >5 (p = 0.018, p = 0.011, p < 0.001, respectively).ConclusionThe presence of a palpable goiter, thyroid weight ≥40 g and thyromental distance <6.5 cm were risk factors associated with difficult intubation in the multivariate regression model.
Long-term adaptation of Escherichia coli to methanogenic co-culture enhanced succinate production from crude glycerol
Authors: Kim Nam Yeun , Kim Su Nyung , Kim Ok Bin 
Published: December 2017

Abstract
Escherichia coli can hardly grow anaerobically on glycerol without exogenous electron acceptor. The formate-consuming methanogen Methanobacterium formicicum plays a role as a living electron acceptor in glycerol fermentation of E. coli. Wild-type and mutant E. coli strains were screened for succinate production using glycerol in a co-culture with M. formicicum. Subsequently, E. coli was adapted to glycerol fermentation over 39 rounds (273 days) by successive co-culture with M. formicicum. The adapted E. coli (19.9 mM) produced twice as much succinate as non-adapted E. coli (9.7 mM) and 62% more methane. This study demonstrated improved succinate production from waste glycerol using an adapted wild-type strain of E. coli with wild-type M. formicicum, which is more useful than genetically modified strains. Crude glycerol, an economical feedstock, was used for the cultivation. Furthermore, the increase in methane production by M. formicicum during co-culture with adapted E. coli illustrated the possibility of energy-saving effects for the fermentation process.
Current progress and outcomes of clinical trials on using epidermal growth factor receptor‐tyrosine kinase inhibitor therapy in non‐small cell lung cancer patients with brain metastases

Published: December 2017

AbstractNon‐small cell lung cancer (NSCLC) continues to be one of the major causes of cancer‐related deaths worldwide, and brain metastases are the major cause of death in NSCLC patients. With recent advances in understanding the underlying molecular mechanism of NSCLC development and progression, mutations in epidermal growth factor receptor (EGFR) have been recognized as a key predictor of therapeutic sensitivity to EGFR tyrosine kinase inhibitors (TKIs). Using EGFR‐TKI alone or in combination with standard treatments such as whole‐brain radiotherapy and surgery has been an effective strategy for the management of brain metastasis. Particularly, a newer generation of EGFR‐TKIs, including osimertinib and AZD3759, has been developed. These new EGFR‐TKIs can cross the blood–brain barrier and potentially treat EGFR‐TKI resistance and improve prognosis. In this article, current progress and outcomes of clinical trials on the use of EGFR‐TKIs for treating NSCLC patients with brain metastasis will be reviewed.
Legal Consciousness of the Leftover Woman: Law and Qing in Chinese Family Relations
Authors: LIU Qian 
Published: December 2017

AbstractThis paper analyses how the interaction of law andqing(情) shapes ordinary Chinese people’s legal consciousness. Ordinary Chinese people rely onqing, or the normal feelings, or attitudes of the public, to judge whether a particular law is just and how they should react to the law. By investigating Chinese leftover women’s legal consciousness regarding marriage and childbearing, this article has developed a theory to discuss Chinese people’s different forms of legal consciousness either when the law is in opposition toqingor when it is in alliance withqing.I argue that these variations of legal consciousness result from the dynamic relationship betweenqingand different types and levels of legality, including state law.
Reasons behind current gender imbalances in senior global health roles and the practice and policy changes that can catalyze organizational change
Authors: Newman C. , Chama P.K. , Mugisha M. , Matsiko C.W. , Oketcho V. 
Published: December 2017

AbstractThe paper distils results from a review of relevant literature and two gender analyses to highlight reasons for gender imbalances in senior roles in global health and ways to address them. Organizations, leadership, violence and discrimination, research and human resource management are all gendered. Supplementary materials from gender analyses in two African health organizations demonstrate how processes such as hiring, deployment and promotion, and interpersonal relations, are not ‘gender-neutral’ and that gendering processes shape privilege, status and opportunity in these health organizations. Organizational gender analysis, naming stereotypes, substantive equality principles, special measures and enabling conditions to dismantle gendered disadvantage can catalyze changes to improve women's ability to play senior global health roles in gendered organizations. Political strategies and synergies with autonomous feminist movements can increase women's full and effective participation and equal opportunities. The paper also presents organizational development actions to bring about more gender egalitarian global health organizations.

Abstract
Sixteen intestinal helminth species were recovered from 271 necropsied stray dogs during a survey undertaken in Raoued and Soukra, two northeastern rural regions of Tunisia. Recorded parasites included trematodes (Brachylaemus sp., Phagicola italica, Heterophyes heterophyes), cestodes (Echinococcus granulosus, Dipylidium caninum, Diplopylidium noelleri, Mesocestoides lineatus, Mesocestoides litteratus, Taenia hydatigena, Taenia pisiformis, Taenia multiceps), nematodes (Toxocara canis, Ancylostoma caninum, Uncinaria stenocephala, Trichuris vulpis) and one acanthocephalan Macracanthorhynchus hirudinaceus. This is the first record of Brachylaemus sp., P. italica, H. heterophyes, D. noelleri and M. hirudinaceus in dogs from Tunisia. Echinococcus granulosus was found in 5·16% of dogs with a higher intensity of infection recorded in younger animals (303 worms/infected dog). Molecular analysis confirmed E. granulosus sensu stricto as the cause of canine echinococcosis. This epidemiological study investigating the status of intestinal helminths of dogs recorded a prevalence of 98·89% and a mean intensity of 87·62 worms per infected dog and confirmed the infection of 95·14% of dogs with helminths of potential zoonotic concern. Results of this study emphasize the need to interrupt parasite transmission using preventive approaches in zoonoses control programmes mainly against cystic echinococcosis, as well as reducing transmission to other animals by regular dog dosing treatments and proper management of dog populations.

Published: December 2017

AbstractBackground:High-quality trials have the potential to influence clinical practice.Methods:Ten otolaryngology journals with the highest 2011 impact factors were selected and publications from 2010 were extracted. From all medical journals, the 20 highest impact factor journals were selected, and publications related to otolaryngology for 2010 and 2011 were extracted. For all publications, the reporting quality and risk of bias were assessed.Results:The impact factor was 1.8–2.8 for otolaryngology journals and 6.0–101.8 for medical journals. Of 1500 otolaryngology journal articles, 262 were therapeutic studies; 94 had a high reporting quality and 5 a low risk of bias. Of 10 967 medical journal articles, 76 were therapeutic studies; 57 had a high reporting quality and 8 a low risk of bias.Conclusion:Reporting quality was high for 45 per cent of otolaryngology-related publications and 9 per cent met quality standards. General journals had higher impact factors than otolaryngology journals. Reporting quality was higher and risk of bias lower in general journals than in otolaryngology journals. Nevertheless, 76 per cent of articles in high impact factor journals carried a high risk of bias. Better reported and designed studies are the goal, with less risk of bias, especially in otolaryngology journals.
The socio-cultural benefits and costs of the traditional hunting of dugongsDugong dugonand green turtlesChelonia mydasin Torres Strait, Australia

AbstractSignatory states of the Convention on Biological Diversity must ‘protect and encourage the customary use of biological resources in accordance with traditional cultural practices that are compatible with conservation or sustainable use requirements’. Thus the management of traditional hunting of wildlife must balance the sustainability of target species with the benefits of hunting to traditional communities. Conservation policies usually define the values associated with wild meats in terms of income and nutrition, neglecting a wide range of social and cultural values that are important to traditional hunting communities. We elicited the community-defined benefits and costs associated with the traditional hunting of dugongsDugong dugonand green turtlesChelonia mydasfrom communities on two islands in Torres Strait, Australia. We then used cognitive mapping and multidimensional scaling to identify separable groups of benefits (cultural services, provisioning services, and individual benefits) and demonstrate that traditional owners consider the cultural services associated with traditional hunting to be significantly more important than the provisioning services. Understanding these cultural values can inform management actions in accordance with the Convention on Biological Diversity. If communities are unable to hunt, important cultural benefits are foregone. Based on our results, we question the appropriateness of conservation actions focused on prohibiting hunting and providing monetary compensation for the loss of provisioning services only.
De novo synthesis of thiamine (vitamin B1) is the ancestral state in Plasmodium parasites – evidence from avian haemosporidians
Authors: Hellgren Olof , Bensch Staffan , Videvall Elin 
Published: December 2017

AbstractParasites often have reduced genomes as their own genes become redundant when utilizing their host as a source of metabolites, thus losing their own de novo production of metabolites. Primate malaria parasites can synthesize vitamin B1 (thiamine) de novo but rodent malaria and other genome-sequenced apicomplexans cannot, as the three essential genes responsible for this pathway are absent in their genomes. The unique presence of functional thiamine synthesis genes in primate malaria parasites and their sequence similarities to bacterial orthologues, have led to speculations that this pathway was horizontally acquired from bacteria. Here we show that the genes essential for the de novo synthesis of thiamine are found also in avian Plasmodium species. Importantly, they are also present in species phylogenetically basal to all mammalian and avian Plasmodium parasites, i.e. Haemoproteus. Furthermore, we found that these genes are expressed during the blood stage of the avian malaria infection, indicating that this metabolic pathway is actively transcribed. We conclude that the ability to synthesize thiamine is widespread among haemosporidians, with a recent loss in the rodent malaria species.
