Ethical Leadership and Organizational Climate: The Experience of Iranian Nurses

Background: As a legitimate and credible role-model, the ethical nurse leader engages in the proper structuring of the workplace and plays a significant role in improving the organizational climate. Despite the importance of the subject, no studies have yet examined the effect of ethical nursing leadership in improving organizational climates in Iran. Objectives: The study was conducted to explore the ways for improving organizational climate through ethical leadership from Iranian nurses perspective. Methods: The qualitative research method used in this original study was employed to explore the means of improving organizational climate through providing ethical leadership. Data were collected using deep and semi-structured interviews with 17 Iranian nurses in different categories in 2015 in Mashhad, Iran. Sampling started as purposive and then continued as theoretical sampling until data saturation. Data were analyzed basedonthe constant comparative analysis. In order to increase the accuracyandintegrity of the data, Lincoln and Guba’s criteria were used. Results: According to the Iranian nurses interviewed in this study, the ethical leader improves the organizational climate within three dimensions including the work environment, the communication climate, and the ethical climate. The ethical leader creates organizational identification, trust, and solidarityamongnurses. He/she improves the communication atmosphere through understanding and empathy, the creation of trust and the establishment of good and reasonable relationships with others. The ethical leader also develops the ethical climate to internalize ethics in the staff through facilitating ethical practice in the organization. Conclusions: Given the context of nursing practice in Iran, this study helps develop a favorable organizational climate and improve ethics in nursing practice. Creation of an ethical climate by ethical nurse leaders can ultimately be of benefit to the patients, the organization, and the nursing profession.
The Influence of Attitude, Knowledge and Quality on Purchase Intention towards Halal Food: A Case Study of Young Non-Muslim Consumers in Thailand

This paper investigates the influence of attitude, halal knowledge, halal quality on purchase intention towards halal food of young non-Muslim consumers in Thailand. Consequently, total of 600 questionnaires were distributed and 482 usable responses were obtained yielding a response rate of 80.33%. Our results indicated that attitude has a strongest direct influence on intention to purchase and also the results indicated that halal knowledge has a significant effect on attitude towards halal food and had no significant effect on halal purchase intention. Furthermore, halal quality has significant positive influences on the purchase intention among the studied group in Thailand. Therefore, this paper could provide insights important for manufacturers, marketers and policymakers to understand the perspectives of young non-Muslim consumers in Thailand.
Nonlocal Parabolic Integro-differential Equations with Delays

In this paper we consider a parabolic integro-differential equation with delay and a nonlocal boundary condition. We apply the method of semidiscretization in time, also known as the method of lines, to establish the existence and uniqueness of the considered problem. We also establish the continuous dependence of the solution on the initial data. Finally, an application of the established results is demonstrated
Morphosynthesis of Zn-substituted stoichiometric and carbonate hydroxyapatite nanoparticles and their cytotoxicity in fibroblasts

Hydroxyapatite (Ca10(PO4)3(OH)2) (HAp) is crystallographically and chemically similar to the human hard tissues and has been widely researched. The naturally formed HAp has some impurities of some ions, which provides the biocompatibility as well as the nanosized morphologies in the tissues. In this study, the morphosynthesis of zinc-substituted stoichiometric and carbonate hydroxyapatite (Zn:HAp and Zn:CAp) nanoparticles was investigated from the reagents of CaCl2, ZnCl2, and K2HPO4. The initial (Ca + Zn)/P ratios of 1.67 and 2.00 were adjusted by the initial ZnCl2 amount at the Zn/(Ca+Zn) concentration of 0.0-10 mol%. The crystalline sizes of the nanoparticles decreased with increasing the Zn ion amount, suggesting that the Zn substitution significantly suppressed the crystal growth. TEM images of the nanoparticles indicated that all the crystalline sizes are less than 100nm and the needle-like shapes were significantly changed to spherical shapes with increasing the Zn ion substitution to resultantly exhibit the higher surface areas as well as the nanoparticle aggregation states. Furthermore, all the nanoparticle films electrically plated on a silicone substrate give no cytotoxicity, and the Zn:CAp nanoparticle films significantly provided the bioactive properties for fibroblast ingrowth, suggesting the effect of Zn and carbonate ions on the cytocompatibility.
Comparing regret minimization and utility maximization for route choice using the recursive logit model

This paper focuses on the comparison of estimation and prediction results between the random utility maximization (RUM) and random regret minimization (RRM) frameworks for the route choice recursive logit (RL) model. The RL model is originally based on the RUM framework. We propose different versions of the RL model based on the RRM framework, by adapting and extending the model proposed by Chorus. We report estimation results and a cross-validation study for a real network with more than 3000 nodes and 7000 links. The cross-validation results show that one of the proposed extended versions of the RRM-based model has the best out-of-sample fit. While this observation favours the RRM framework, we note that the RRM-based models are computationally more complex to estimate and apply than the RUM-based ones.
Inﬁnite Time Aggregation for the Critical Patlak-Keller-Segel model in R 2

We analyze the two-dimensional parabolic-elliptic Patlak-Keller-Segel model in the whole Euclidean space R 2 . Under the hypotheses of integrable initial data with ﬁnite second moment and entropy, we ﬁrst show local in time existence for any mass of ”free-energy solutions”, namely weak solutions with some free energy estimates. We also prove that the solution exists as long as the entropy is controlled from above. The main result of the paper is to show the global existence of free-energy solutions with initial data as before for the critical mass 8 π / χ . Actually, we prove that solutions blow-up as a delta Dirac at the center of mass when t → ∞ keeping constant their second moment at any time. Furthermore, all moments larger than 2 blow-up as t → ∞ if initially bounded. c (cid:176) 2000 Wiley Periodicals, Inc.
Estimating the impact of systems engineers on systems design processes

In this work we develop an understanding of how systems engineers or system integrators can mediate communication channels within a design organization, leading to increased technical success where otherwise no coordination is observed. The models developed here are offered as alternative explanations for observed communication or coordination gaps between design groups working on connected technical subsystems. The results of analysis of simulated organizational network data indicate that systems engineers in mediating roles can improve the probability of technical success as estimated by communication path length within the organizational network. This suggests that roles beyond those directly involved in design tasks should be considered in organizational models used to predict technical system performance.
Expression of platelet-derived growth factor isoforms and their receptors in cells accumulating in the human atherosclerotic lesion

Atherosclerosis is a progressive and complex disease, which narrows the lumen of arteries and eventually causes cardiovascular complications such as ischaemic heart disease and stroke. Hallmarks of the disease development are; a compromised endothelial barrier, the accumulation of lipids and immunocompetent monocytederived macrophages (MDM) and T-cells, the formation of MDM foam cells, and migration and proliferation of medial arterial smooth muscle cells (SMC) in the innermost layer (intima) of the arterial wall. While lipid-lowering therapy favourably retards atherosclerosis progression by reducing the lipid component of intimai thickenings, there is no effective therapy to control cell accumulation in the intima. A key role in this cellular response has been attributed to the Platelet-Derived Growth Factor (PDGF). The main aims of this thesis were to establish a better understanding of the role of PDGF and its receptors (PDGF-R) in the cellular responses in the complex atherosclerotic plaque by studying human SMC and MDM in simplified in vitro systems. Specifically, I studied i) if the expressions of PDGF isoforms and their receptors are affected by changes in cell phenotype, ii) if this expression is modulated by exogenous cytokines, and iii) if different PDGF homodimers affect major cellular events in the atherosclerotic lesion; proliferation of SMC and migration of MDM. The results showed that human SMC and MDM expressed PDGF and PDGF-Rs in vitro. Both PDGF and PDGF-R genes were independently regulated and showed a complex gene regulatory pattern. The expression of these genes could be influenced by phenotypic changes and cytokines. SMC downregulated PDGF mRNA during dedifferentiation upon serum exposure. In contrast, blood-derived monocytes differentiated to MDM in the presence of serum and increased both PDGF isoform mRNAs, suggesting that PDGF might be important during macrophage differentiation. All tested PDGF homodimers (PDGF-AAL, -AAs, and -BBS) induced SMC proliferation whereas only PDGF-AAL induced directed migration in early MDM and this was coupled to an increase in PDGF-Ra expression. Taken together, these results suggest that PDGF-mediated mechanisms may be involved in cell accumulation in atherosclerotic lesions, influencing proliferation of SMC and chemoattraction of early MDM.
Some ecological aspects of phlebotomine sand flies in an endemic focus of cutaneous leishmaniasis in Iran.

Following annual report of new cases of cutaneous leishmaniasis from different areas of Kuhpayeh district, Esfahan County, an investigation was carried out on some ecological aspects of Phlebotomine sand flies during 2000-2002. Sand flies were collected biweekly from outdoor and indoor resting places with the aid of 30 sticky traps from the beginning to the end of the active season. Female sand flies from rodent burrows were dissected and examined for the presence of promastigote infection. Blood meals of engorged sand flies were identified by ELISA method. Totally, 4993 sand flies were collected and identified. The following species were found indoors: P. papatasi, P. sergenti, P. caucasicus, P. mongolensis, P. alexandri, P. ansarii, P. major, P. kandelakii, S. sintoni, and the subsequent species were found outdoors: P. papatasi, P sergenti, P. caucasicus, P. mongolensis, P. ansarii, P. major, S. sintoni, S. dentata, S. pawlowskyi. The sand flies active season began from May till October in this region. Natural promastigote infections observed in 1.06% of P. papatasi and also in one out of four of P. caucasicus. The human and rodent blood indices in P. papatasi were 61.9% and 20.69%, respectively. It seems that P. papatasi is the probable vector among rodents and also transmit Leishmania major, the causative agent of zoonotic cutaneous leishmaniasis to man, and P. caucasicus transmit the agent of the disease among rodents.
Affiliation, Reciprocal Relationships and Peer Pressure in Knowledge Sharing in Public Universities in Malaysia

The aim of this study was to examine the influence of some dimensions of social capital toward knowledge sharing intention. The theoretical framework and measurement tool was derived based on the three factors of social capital dimension (sense of affiliation, reciprocal relationships and peer influence) and knowledge sharing intention. A survey was conducted and obtained a total of 235 valid respondents. The theoretical model was examined using structural equation modeling. The findings confirm that employees with high sense of affiliation and reciprocal relationships are more willing to conform to social pressure in sharing their knowledge. The results also confirm that peer pressure in the public institution will result to higher propensity in knowledge sharing among colleagues and peers.
Dynamics of solar bleaching in the intertidal reef coral Goniastrea aspera at Ko Phuket, Thailand

The bleaching response in intertidal Goniastrea aspera (Verrill) was investigated immediately a t the onset of a natural bleaching event caused primarily by elevated solar irradiance. Bleaching was found to involve a significant decrease in zooxanthellae density and a significant reduction in chlorophyll c content of zooxanthellae. In contrast chlorophyll a content of zooxanthellae appeared to increase in bleached compared to normally pigmented tissues, an effect lvhich may have been the result of interference of chlorophyll breakdown products with the pigment analysis. Bleaching damage was restricted a t the cellular level to those host endodermal cells harbouring zooxanthellae, both of which exhibited cellular degradation. In bleached tissues, in situ degradation of zooxanthellae, prior to their loss from host tissues, appeared to be the principal factor associated with reduction in algal density The results highlight that the mechanism of bleaching IS a complex response involving changes In the symbiotic association between specific host and zooxanthella cells, zooxanthella denslties and pigment content.
Expression of microRNAs in the plasma of patients with acute gouty arthritis and the effects of colchicine and etoricoxib on the differential expression of microRNAs

Introduction To determine the microRNA (miRNA) expression profiles in the plasma of acute gouty arthritis (AGA) patients and investigate the effects of colchicine and etoricoxib treatment on the differential expression of miRNAs. Material and methods Exiqon miRCURYLNA microRNA Array was used for miRNA expression profiling in AGA. Two of the 21 differentially expressed miRNAs were confirmed using quantitative real-time polymerase chain reaction (qRT-PCR). A randomized, double-blind, parallel-controlled design was used to divide 160 AGA patients into colchicine and etoricoxib groups. Changes in 2 differentially expressed miRNAs, interleukin-1 (IL-1) β, cyclooxygenase-2 (COX-2) and joint pain scores were detected. Results Compared with normal subjects and asymptomatic hyperuricemia (HUA) patients, plasma of AGA contained 21 differentially expressed miRNAs. qRT-PCR indicated specific downregulation of miR-223-3p and miR-451a in AGA. There were no statistically significant differences in the baseline characteristics between colchicine and etoricoxib groups. Furthermore, no significant difference in joint pain scores after 5- and 10-day treatment were found between groups (p > 0.05). Comparison of differences between pre- and 5-day post-treatment values confirmed that the upregulation of miR-223-3p and downregulation of IL-1β induced by colchicine were more significant than etoricoxib (p < 0.05). However, the latter outperformed the former in the upregulation of miR-451a and downregulation of COX-2 (p < 0.05). After 10-day treatment, the magnitude of miR-223-3p upregulation and IL-1β downregulation in the colchicine group was significantly higher than in the etoricoxib group, while the etoricoxib group had higher expression of miR-451a and lower expression of COX-2 than the colchicine group (p < 0.05). Conclusions In AGA patients, 21 differentially expressed miRNAs were detected in the plasma. Colchicine could upregulate miR-223-3p and downregulate IL-1β in the plasma, while etoricoxib may treat AGA by upregulating miR-451a and downregulating COX-2.
"Gtool5": a Fortran90 library of input/output interfaces for self-descriptive multi-dimensional numerical data

Abstract. A Fortran90 input/output library, "gtool5", is developed for use with numerical simulation models in the fields of Earth and planetary sciences. The use of this library will simplify implementation of input/output operations into program code in a consolidated form independent of the size and complexity of the software and data. The library also enables simple specification of the metadata needed for post-processing and visualization of the data. These aspects improve the readability of simulation code, which facilitates the simultaneous performance of multiple numerical experiments with different software and efficiency in examining and comparing the numerical results. The library is expected to provide a common software platform to reinforce research on, for instance, the atmosphere and ocean, where a close combination of multiple simulation models with a wide variety of complexity of physics implementations from massive climate models to simple geophysical fluid dynamics models is required.
Synthesis of novel 2-substituted benzimidazole derivatives as potential anti microbial agents

In the present study, a novel series of 2-substituted benzimidazole derivatives were synthesized and characterized by means of IR, 1H-NMR, 13C- NMR, mass spectral and elemental analysis. The compounds were screened for antibacterial (Staphylococcus aureus ATCC9144, Staphylococcus epidermidis ATCC 155, klebsiella pneumoniae ATCC 29665 and Esherichia coli ATCC 25922) and antifungal (Candida albicans ATCC 2091 and Aspergillus niger ATCC 9029) activities. The Minimum Inhibitory Concentrations was determined by agar streak dilution method. 1-(4-(1H-benzo[d]imidazol-2-yl)phenyl)-3-chloro-4-(4-nitro phenyl)azetidin-2-one (3a) was found to exhibit the most potent in vitro antimicrobial activity with MIC of 15, 17, 19, 9, 11 and 15 μg/mL against E.coli, K.pneumoniae, S.aureus, S.epidermidis, C.albicans and A.niger respectively. All the other compounds exhibited moderate activity against the bacterial and fungal organism tested.
Kinetics and Energetics of Protein Sorting

Currently, there are four models for the sorting of protein into different cellular compartments. Each model makes an attempt to explain how the interactions of the essential components of vesicle formation, ARF1 or Sar1 GTPase, GTPase activating protein, coatomer proteins, and p24 proteins, lead to high fidelity protein sorting. Each model is supported by a subset of the available genetic, morphological, biochemical, and kinetic data.

Tropospheric ozone information from satellite‐based polarization measurements

[1] Many current and planned future satellite missions aim at the retrieval of tropospheric ozone from reflectance spectra. However, it is difficult to distinguish between stratospheric and tropospheric ozone on the basis of reflectance spectra only. In this paper we show that satellite-based polarization measurements of backscattered light contain valuable additional information on the tropospheric ozone profile. In contrast to the reflectance the polarization properties of backscattered light show higher sensitivity to ozone in the troposphere than to ozone in the stratosphere. This is because the polarization is most affected by ozone at that altitude where most scattering takes place, which is in the troposphere for wavelengths greater than ∼300 nm. Retrievals performed on synthetic Global Ozone Monitoring Experiment 2 data show that the vertical resolution of the tropospheric ozone profile is significantly improved if polarization measurements are used in addition to the reflectance spectrum. Problems that are currently encountered in tropospheric ozone retrieval from reflectance spectra may be solved by using additional polarization measurements.
Continuous-time modeling of random searches: statistical properties and inference

Mathematical modeling of random searches is of great relevance in the fields of physics, chemistry, biology or modern ecology. A large number of existing studies record the search movement at equidistant time intervals and model such time series data directly with discrete-time random walks, such as Lévy flights and correlated random walks. Given the increasing availability of high-resolution observation data, statistical inference for search paths based on such high-resolution data has recently become one of the major interests and has raised an important issue of robustness of random walk models to the sampling rate, as estimation results for the discrete observation data are found to be largely different at different sampling rates even when the underlying movement is supposedly independent of scale. To address this issue, in this paper, we propose to model the continuous-time search paths directly with a continuous-time stochastic process for which the observer makes statistical inference based on its discrete observation. As continuous-time counterparts of Lévy flights, we consider two-dimensional Lévy processes and discuss the relevance of those models based upon advantages and limitations in terms of statistical properties and inference. Among the proposed models, the Brownian motion is most tractable in various ways while its Gaussianity and infinite variation of sample paths do not well describe the reality. Such drawbacks in statistical properties may be remedied by employing the stable and tempered stable Lévy motions, while those models are less tractable and cause an issue in statistical inference.
Hawking Radiation of a Charged Black Hole in Quantum Gravity

We study black hole radiation of a Reissner-Nordstrom black hole with an electric charge in the framework of quantum gravity. Based on a canonical quantization for a spherically symmetric geometry, under physically plausible assumptions, we solve the Wheeler-De Witt equation in the regions not only between the outer apparent horizon and the spatial infinity but also between the spacetime singularity and the inner apparent horizon, and then show that the mass loss rate of an evaporating black hole due to thermal radiation agrees with the semiclassical result when we choose an integration constant properly by physical reasoning. Furthermore, we also solve the Wheeler-De Witt equation in the region between the inner Cauchy horizon and the outer apparent horizon, and show that the mass loss rate of an evaporating black hole has the same expression. The present study is the natural generalization of the case of a Schwarzschild black hole to that of a charged Reissner-Nordstrom black hole.
