Responding to Organizational Identity Threats: Exploring the Role of Organizational Culture

In this paper, we present a longitudinal study of organizational responses to environmental changes that induce members to question aspects of their organization’s identity. Our findings highlight the role of organizational culture as a source of cues supporting “sensemaking” action carried out by leaders as they reevaluate their conceptualization of their organization, and as a platform for “sensegiving” actions aimed at affecting internal perceptions. Building on evidence from our research, we develop a theoretical framework for understanding how the interplay of construed images and organizational culture shapes changes in institutional claims and shared understandings about the identity of an organization.
Do L2 Speakers’ Problems Originate in Syntax or Syntax-discourse Interface? ： Importance of the Study of Acquisition of Pronouns by English Speakers of L2 Japanese

In this article the significance of the study focusing on the acquisition of pronouns by English learners/speakers of L2 Japanese is discussed. The recent studies have reported that optionality is found even in the L2 grammar of near-native or advanced level learners (Sorace 1993, Robertson and Sorace 1999, Montul and Slabakova 2003, Hopp 2004). Optionality means that “two structures are used interchangeably by a single learner” (Bong 2006: 3). If this is the case, does it mean that interlanguage grammar is not fully UGconstrained? Why does optionality exist ? Based on the L2 study of Pérez-Leroux and Glass (1999), the possible study and its procedure, the hypotheses and expected results are discussed including the theoretical background. The results would account for the role of UG in L2 grammar, the role of L1 and fossilization to some extent. They also contribute to the progress of both the SLA theory and UG theory.
Minimized Low-Profile Wideband Antennas Using High Impedance Surface

This paper proposes minimized low-profile wideband antenna by employing high impedance surface (HIS), for wireless application scenarios at radio frequency, microwave, and even terahertz. To validate this concept with low cost and easy measurement, two prototypes at radio frequency are fabricated and tested. Firstly, antenna with dielectric-substrate reflector is proposed and analyzed and 4 × 6 HIS array is employed to minimize the antenna size to , while maintaining antenna performances such as bandwidth, gain, and directive radiation. Secondly, a substrate-less HIS is proposed to improve the antenna bandwidth from 36% to 52% and also reduces the antenna weight by 72%.
Preparation and in vitro Bactericidal and Fungicidal Efficiency of NanoSilver/Methylcellulose Hydrogel

: In this work we describe the preparation of NanoSilver/methylcellulose hydrogel containing silver nanoparticles (NPs) for topical bactericidal applications. Highly concentrated dispersion of silver NPs as high as of 5g/L of silver with diameter of 10nm was prepared by reduction of AgNO3 via strong reducing agent NaBH4. Silver NPs were stabilized by addition of sodium polyacrylate in order to prevent their aggregation at such high concentration. This way synthesized silver NPs were subsequently incorporated into methylcellulose suspension at elevated temperature resulting in formation of NanoSilver/methylcellulose hydrogel when temperature cooled down to laboratory conditions. In vitro antibacterial activity assay proved high bactericidal and fungicidal efficiency of silver NPs alone in the form of dispersion as well as in the form of hydrogel against broad spectrum of bacteria and yeasts including highly multiresistant strains such as methicillin-resistant Staphylococcus aureus. A very low concentrations of silver as low as 0.84mg/L Ag in as-prepared dispersion gave antibacterial performance. NanoSilver/methylcellulose hydrogel showed antibacterial action at the lowest used silver concentration equal to 25mg/L. Such prepared NanoSilver/methylcellulose hydrogel represent promising topical antimicrobial formulation for treatment of burns and wounds.
Cold treatment of “Hass” avocado (Persea americana (Lauraceae)) infested by Thaumatotibia leucotreta (Lepidoptera: Tortricidae) as an additional component of a systems approach

Abstract Thaumatotibia leucotreta is of phytosanitary importance, and this paper addresses mitigating measures to reduce the risk of its introduction with fresh avocado fruit into importing countries. Applying a cold treatment of 2°C pulp temperature for 20 days resulted in a single T. leucotreta survivor from 28,380 individuals treated. When this result is considered as part of a systems approach where the second component is the poor host status, then the probability of accidentally importing live larvae was lowered to levels exceeding established phytosanitary security levels.
A simple, low-cost CVD route to thin films of BiFeO3 for efficient water photo-oxidation

A novel method for preparation of BiFeO3 films via a simple solution-based CVD method is reported using for the first time a single-source heterobimetallic precursor [CpFe(CO)2BiCl2]. BiFeO3 films display ferroelectric and ferromagnetic ordering at room temperature and possess direct band-gaps between 2.0 and 2.2 eV. Photocatalytic testing for water oxidation revealed high activities under UVA (365 nm) and simulated solar irradiation, superior to that exhibited by a commercial standard (Pilkington Activ® TiO2 film) resulting in an apparent quantum yield of ∼24%.
Assigment of maximal acceleration of a car as a function of some independent variables

The procedure for calculation of a car maximal acceleration during speeding up with changing shifts of a gearbox in dependence on several independent parameters has been presented in the paper. The parameters taken into consideration are the angle of a road slope and the additional vehicle load. The maximal acceleration for investigated vehicle category has been calculated on the basis of many numerical simulations. During these simulations the dynamics of vehicle motion has been modelled for different road conditions. In order to approximate the results of acceleration the power polynomials were applied. The least square method has been used in calculations of polynomial coefficients. The results of modelling of the vehicles dynamics concern two passenger cars and one heavy duty car. Simulations of speeding up were obtained using the model of vehicle dynamics. Especially, model of vehicle, the traction characteristic of the passenger car with SI engine, the maximal driving force on wheels during vehicle acceleration calculated on the basis of traction characteristic, the maximal acceleration of the passenger cars and according to the model of vehicle dynamics during speeding up with changing shifts of a gearbox in dependence on different parameters of road slope and vehicle load are presented in the paper.
Fabrication of Reliable Metal Field Emitter Arrays Using Isotropic Silicon Etching and Oxidation

This paper describes a fabrication and characterization of metal field emitter to achieve low voltage and high current operation. The key element of the fabrication process is that the isotropic silicon etching and oxidation process used in silicon tip fabrication are utilized for gate hole size reduction and gate oxide layer formation. A reliable structure with a small gate hole can be easily obtained. Metal FEAs were fabricated in order to demonstrate the validity of the new process. Submicron gate apertures were successfully obtained from 2.25 μm-diameter disk patterns defined by a conventional contact mask aligner. The required gate voltage to obtain an anode current of 0.1 μA/tip was 54 V and emission currents above 20 μA/tip were stable at a gate bias of 96V without any disruption.

Here we describe recently developed, extended or improved services, including an animated structure-presentation widget (PDBportfolio), a widget to graphically display the coverage of any UniProt sequence in the PDB (UniPDB), chemistry- and taxonomy-based PDB-archive browsers (PDBeXplore), and a tool for interactive visualization of NMR structures, corresponding experimental data as well as validation and analysis results (Vivaldi).
Changes in the levels of DNA methyltransferases and demethylases in the nucleus accumbens in cocaine-induced behavioural sensitisation in rats with different exploratory activity

Epigenetic modifications, such as DNA methylation, are involved in the development of cocaineinduced behavioural sensitisation. This study investigated the development and expression of cocaine-induced behavioural sensitisation in rats with high and low exploratory activity (HE and LE, respectively), and the drug-induced changes in the mRNA levels of Dnmt and Tet family genes in the nucleus accumbens. Only LE-animals had increased locomotor activity over continuous test sessions in response to repeated cocaine (12 mg/kg) administration and they developed a more pronounced behavioural sensitisation. Repeated cocaine treatment resulted in upregulated mRNA of Dnmt3b in HE-, but not in LE-rats, and upregulated mRNA levels of Tet3 in both. Thus, our results suggest that LEand HE-rats differ in the development and expression of cocaine-induced behavioural sensitisation. The aim of future research is to further examine, whether the observed changes in Dnmt and Tet levels could explain the behavioural differences between HEand LE-animals in response to cocaine.
Short time, few available resources and need for measuring the strain in parents of children with chronic diseases: Utility of the Family Strain Questionnaire, Short Pediatric Form

Measuring caregivers’ strain due to chronic disease of childhood is an important complement of the quality of children’s care but it may imply resources not always available. Short questionnaires may then be useful, especially for clinical nurses and care-teams. In this study we present the Family Strain Questionnaire-Short Pediatric Form (FSQ-SPF), which is brief, easy to use, and does not require any specific psychological training. The questionnaire was administered to 96 parents of children affected by genetic/congenital or acquired diseases recruited at two pediatric hospitals. The psychometric properties were analyzed in the context of the requirements for scale construction of the Rasch model. The characteristics of the parents and their levels of strain were then estimated. The parents analyzed (n.96) showed to suffer from severe strain over time, which was independent of the severity of the child’s disability. This was particularly true for mothers with lower levels of education (i.e. one-third of the sample). Forty-four percent of these mothers experienced a difficult relationship with their partner. In general, more than 40% of the subjects declared economic difficulties, reduced social life and problems to move to hospital or for medical visits. The FSQ-SPF seems to be a useful and practical instrument for the evaluation of caregivers' strain in a pediatric/adolescent context. It provides an appropriate and brief screening test, helping to target interventions and improving the quality of care.
Wilson Lines and Holographic Entanglement Entropy in Galilean Conformal Field Theories

In this paper we present in more detail a construction using Wilson lines and the corresponding dual Galilean conformal field theory calculations for analytically determining holographic entanglement entropy for flat space in $2+1$ dimensions first presented in A. Bagchi, R. Basu, D. Grumiller, and M. Riegler, Phys. Rev. Lett. 114, 111602 (2015). In addition, we show how the construction using Wilson lines can be expanded to flat space higher-spin theories and determine the thermal entropy of (spin-3 charged) flat space cosmologies using this approach.
Characterization of NMDAR-Independent Learning in the Hippocampus

It is currently thought that memory formation requires the activation of NMDA receptors (NMDARs) in the hippocampus. However, recent studies indicate that these receptors are not necessary for all forms of learning. The current experiments examine this issue using context fear conditioning in mice. First, we show that context fear can be acquired without NMDAR activation in previously trained animals. Mice trained in one environment (context A) are subsequently able to learn about a second environment (context B) in the presence of NMDAR antagonists. Second, we demonstrate that NMDAR-independent learning requires the hippocampus and is dependent on protein synthesis. However, unlike NMDAR-dependent learning, it is not contingent on the expression of activity-regulated cytoskeleton-associated protein (Arc). Lastly, we present data that suggests NMDAR-independent learning is only observed when recently stimulated neurons are reactivated during conditioning. These data suggest that context fear conditioning modifies synaptic plasticity mechanisms in the hippocampus and allows subsequent learning to occur in the absence of NMDAR activation.
A bibliometric analysis of highly cited articles in materials science

The aim of the present study is to identify and analyse the characteristics of the highly cited articles in materials science, including eight Web of Science categories: multidisciplinary materials science, coatings and films materials science, biomaterials materials science, ceramics materials science, composites materials science, paper and wood materials science, characterization and testing materials science, and textiles materials science within the publication year from 1900 to 2011 based on Science Citation Index-Expanded. Articles that have been cited at least 100 times since publication to 2011 were assessed regarding their distribution in indexed journals. The citation lives of the highly cited articles depending on citations in the publication year, recent years and years after publication were applied for the impact of articles. A new indicator, the Y-index, was applied to assess publication quantity and the characteristics of contribution to articles. Results showed that 14,044 highly cited articles were published between 1900 and 2010. Among them, 70% were published in 1990s and 2000s, and 48% originated from the US. Langmuir and Journal of the Electrochemical Society hosted the highly cited articles. Most top cited articles in the publication year would not be top cited in recent years. Y-index results showed that Massachusetts Institute of Technology, USA had high articles publication potential as well as published the most first author and corresponding author articles. Geim and Novoselov who are the 2010 Nobel laureates, published the most potential article in materials science. Y-index showed that Inoue and Xia had the highest publication performance but different publication characteristics.
TRIM16 controls turnover of protein aggregates by modulating NRF2, ubiquitin system, and autophagy: implication for tumorigenesis

ABSTRACT Protein misfolding and protein aggregation are linked to several diseases commonly called as proteinopathies, which include cancer. Understanding the mechanisms of proteostasis could provide newer strategies to combat proteinopathies. We have recently demonstrated a new mechanism where we found that TRIM16 (tripartite motif-containing protein 16) utilizing NRF2-p62 axis and autophagy streamlines the safe disposal of misfolded proteins to maintain protein homeostasis.
Exogenous Ketone Supplements Reduce Anxiety-Related Behavior in Sprague-Dawley and Wistar Albino Glaxo/Rijswijk Rats

Nutritional ketosis has been proven effective for seizure disorders and other neurological disorders. The focus of this study was to determine the effects of ketone supplementation on anxiety-related behavior in Sprague-Dawley (SPD) and Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. We tested exogenous ketone supplements added to food and fed chronically for 83 days in SPD rats and administered sub-chronically for 7 days in both rat models by daily intragastric gavage bolus followed by assessment of anxiety measures on elevated plus maze (EPM). The groups included standard diet (SD) or SD + ketone supplementation. Low-dose ketone ester (LKE; 1,3-butanediol-acetoacetate diester, ~10 g/kg/day, LKE), high dose ketone ester (HKE; ~25 g/kg/day, HKE), beta-hydroxybutyrate-mineral salt (βHB-S; ~25 g/kg/day, KS) and βHB-S + medium chain triglyceride (MCT; ~25 g/kg/day, KSMCT) were used as ketone supplementation for chronic administration. To extend our results, exogenous ketone supplements were also tested sub-chronically on SPD rats (KE, KS and KSMCT; 5 g/kg/day) and on WAG/Rij rats (KE, KS and KSMCT; 2.5 g/kg/day). At the end of treatments behavioral data collection was conducted manually by a blinded observer and with a video-tracking system, after which blood βHB and glucose levels were measured. Ketone supplementation reduced anxiety on EPM as measured by less entries to closed arms (sub-chronic KE and KS: SPD rats and KSMCT: WAG/Rij rats), more time spent in open arms (sub-chronic KE: SPD and KSMCT: WAG/Rij rats; chronic KSMCT: SPD rats), more distance traveled in open arms (chronic KS and KSMCT: SPD rats) and by delayed latency to entrance to closed arms (chronic KSMCT: SPD rats), when compared to control. Our data indicates that chronic and sub-chronic ketone supplementation not only elevated blood βHB levels in both animal models, but reduced anxiety-related behavior. We conclude that ketone supplementation may represent a promising anxiolytic strategy through a novel means of inducing nutritional ketosis.
Stable Isotope Markers Differentiate between Mass-Reared and Wild Lepidoptera in Sterile Insect Technique Programs

Abstract In this study we identified a number of moth (Lepidoptera) species that are potential targets for the sterile insect technique (SIT), and we assessed the feasibility of using stable isotope signatures as markers to distinguish mass-reared from wild moth species. Large natural differences in the isotopic signatures of commercially available sugars render them novel markers for mass-reared insects. Sugar beet (Beta vulgaris L.; Caryophyllales: Amaranthaceae), a C3 plant, has a stable isotopic signature (a measure of the ratio of the stable isotopes 13C:12C) of around -27‰ relative to Vienna Pee Dee Belemnite (VPDB; the international C isotope standard for the stable isotopes, 13C and 12C), and sugarcane (Saccharum spp.; Poales: Poaceae), a C4 plant, has an isotopic signature of around -11‰. Thus by means of such a distinct isotope ratio in the sugar in the diet, mass-reared insects can be easily distinguished from wild insects with a high degree of certainty. It was shown that the method could be extended using a multiple isotope approach, with 15N or a full suite of C, N, S and O isotopes. Intrinsic isotope marking of mass-reared moths proved to be an accurate means of distinguishing wild from mass-reared populations, based on isotopic differences between the wild host plant species and the diets used in mass-rearing, which where possible, had been manipulated to contain the isotopically divergent sugar type. This intrinsic labeling using stable isotopes could be useful in the assessment of the quality of mass-reared moths, because a stable isotope is a marker that does not affect the insect in any detrimental manner.
An Analysis of a Double-layer Electromagnetic Shield for a Universal Contactless Battery Charging Platform

A patented double-layer planar structure is employed to shield the electromagnetic (EM) field at the bottom of a universal charging platform. The double-layer consists of a layer of soft ferromagnetic material and a layer of conductive material. Thin 4F1 ferrite plate and the copper sheet are used in this example. This shielding technique is analyzed with the extended transmission line theory. With the formulas presented, the shielding effectiveness (SE) of both single-layer shield and double-layer shield could be calculated out directly, without using finite-element software. A classical transmitting-receiving loop measurement has been carried out to evaluate the SE of single ferrite shield, single copper shield and double-layer shield respectively. Calculated and measured results in the working frequency range of the charging platform from 100 kHz to 500 kHz confirm that the double-layer shield has obviously better SE than single-layer shield and can achieve a SE above 40dB, which is commonly accepted by the industry. Finally, the potential of this double-layer shielding technique for a wide range of power electronic applications is discussed.
Implementation of E-education in Africa via Space Networks

In this paper is introduced an advanced E-education provision in remote dispersed communities, such as rural, remote, mobile, agriculture, mining, construction, surveying, military, tourism and so on, based on the specific needs and requirements, implies significant broadband connectivity requirements, timely and quality-assured content delivery of service, applications and interactivity. The E-education solutions of distance learning and training for remote and rural areas, which are out of range of terrestrial and short distance wireless telecommunications facilities, cannot provide the broadband access without space-enabled communication infrastructures, such as satellite constellations and Stratospheric Platform Systems (SPS) or High Altitude Platforms (HAP). The paper also discusses the integration challenges that are presented by combining use of the space solutions for implementation Education and learning in urban, rural and mobile environments. The configuration of in-house design and development of Space Segment, installation of the scale-down Digital Video Broadcasting-Return Channel via Satellite (DVB-RCS) Hub as a Gateway, Ground Network and Interactive VSAT, known as Fixed Interactive Terminals (FIT), for E-education, distance learning and staff training initiative in Africa are described.
