The effect of food festival quality on place attachment and destination recommendation intention through festival experience and festival satisfaction: The case of the Didim International Olive Festival

Abstract This study explores empirically the effect of festival quality on place attachment and destination recommendation intentions through festival experience and festival satisfaction. A survey was conducted by using a self-administered questionnaire distributed to festival visitors at the third International Olive Festival organized in Didim, Turkey. Data from a convenience sample of participants, producing 186 usable questionnaires, was tested in a structural equation model. The findings demonstrated that the festival quality designed and provided by the festival organizer predicts festival experiences, which in turn significantly affects visitors’ festival satisfaction and destination recommendation intention. Satisfaction with the festival experience also significantly influences visitors’ attachment to the place and their destination recommendation intention. Festival visitors who are attached to the place tend to recommend it. The implications for festival organizers and the study’s limitations are also discussed.
A Situation-Aware Scheme for Efficient Device Authentication in Smart Grid-Enabled Home Area Networks

Home area networks (HANs) are the most vulnerable part of smart grids since they are not directly controlled by utilities. Device authentication is one of most important mechanisms to protect the security of smart grid-enabled HANs (SG-HANs). In this paper, we propose a situation-aware scheme for efficient device authentication in SG-HANs. The proposed scheme utilizes the security risk information assessed by the smart home system with a situational awareness feature. A suitable authentication protocol with adequate security protection and computational and communication complexity is then selected based on the assessed security risk level. A protocol design of the proposed scheme considering two security risk levels is presented in the paper. The security of the design is verified by using both formal verification and informal security analysis. Our performance analysis demonstrates that the proposed scheme is efficient in terms of computational and communication costs.
Effects of verb–construction association on second language constructional generalizations in production and comprehension

How strongly a verb is associated with a construction plays a crucial role in the learning of argument structure constructions. We examined the effect of verb–construction association strength on second language (L2) constructional generalization by analysing L2 learners’ production and comprehension of two complex constructions (i.e. ditransitive and resultative), comparable in constructional complexity and input frequency but distinctive in verb–construction association. Using a learner corpus study, we found greater verbal usage variability in the production of ditransitive rather than resultative constructions. The results of an acceptability judgment task indicated that L2 learners accepted the ditransitive sentences regardless of whether they contained high-frequency or low-frequency verbs, but learners were more likely to accept the resultative sentences when they read high-frequency rather than low-frequency verbs. These findings suggest that verb–construction association affects the learning of argument structure constructions, supporting its contribution to the constructional generalization.
Knowledge and practices of nurses caring for patients with endotracheal tube admitted to intensive care units in National Hospital of Sri Lanka

Background Artificial air way is utilized to facilitate mechanical ventilation and the endotracheal tube (ETT) is most used. The objective was to assess the intensive care unit (ICU) nurses’ knowledge and practice in caring for patients with endotracheal tube and their associated factors in National Hospital of Sri Lanka (NHSL). Materials and methods A cross sectional hospital-based study was done among nurses having more than 6 months working experience in all ICUs of NHSL. A self-administered questionnaire was developed using American Association of Respiratory Care (AARC) clinical Practice guideline 2010. Data was analyzed by using SPSS statistical package version 16. Results The majority (91%) had almost 10 years of ICU experience. Mean age was 31.74 years (SD± 5.69). Only half had good knowledge (50.8%) on endotracheal tube care. Mean knowledge was 69.7 ±12.662SD. Majority had good knowledge on oral care (98.9%), humidification (95.1%) and optimal cuff pressure (83.1%). Knowledge was poor for statements on “oral secretions may pool above the cuff leading to ventilator associated pneumonia” (VAP) (12%), selecting suitable suction catheter (44%) and relationship with vaporized water and micro-organism will lead to aspirations (18%). Reported correct practices was 57.8% (N= 107). Only 18% had practiced proper oral hygiene in mechanically ventilated patients. The majority (63.2%) reported incorrect practices related to suction method and measuring the suction catheter length. Conclusions Most nurses were unaware of the current protocols or guidelines related to ET tube care. The most significant deficiencies were related to tracheal complications and activities that cause tracheal trauma, and activities which can lead to serious and harmful effects to patients.
A Coevolutionary Framework for Constrained Multiobjective Optimization Problems

Constrained multiobjective optimization problems (CMOPs) are challenging because of the difficulty in handling both multiple objectives and constraints. While some evolutionary algorithms have demonstrated high performance on most CMOPs, they exhibit bad convergence or diversity performance on CMOPs with small feasible regions. To remedy this issue, this article proposes a coevolutionary framework for constrained multiobjective optimization, which solves a complex CMOP assisted by a simple helper problem. The proposed framework evolves one population to solve the original CMOP and evolves another population to solve a helper problem derived from the original one. While the two populations are evolved by the same optimizer separately, the assistance in solving the original CMOP is achieved by sharing useful information between the two populations. In the experiments, the proposed framework is compared to several state-of-the-art algorithms tailored for CMOPs. High competitiveness of the proposed framework is demonstrated by applying it to 47 benchmark CMOPs and the vehicle routing problem with time windows.
Haematological parameters in patients with rheumatoid arthritis and gene variants HLA-DRB1 * 04 and HLA-DRB1 * 03

Rheumatoid arthritis is a polygenic disease of unknown etiology, occurs worldwide in both developed and underdeveloped countries and involves all races. The aim of this study is to determine the correlation between hematological parameters (DBC and ESR) and biomarkers of inflammation (CRP) in patients with RA predisposing gene variants HLA-DRB1*04 or HLA-DRB1*03. This study analyzed the results of hematological and biochemical parameters of 33 patients diagnosed with RA, carriers ofgene variants of HLA-DRB1*04 or HLA-DRB1*03, and 33 subjects of control group non-carriers for HLA-DRB1*04 or HLA-DRB1*03. All hematological parameters (DBC) were analyzed on a Beckman Coulter DxH 800 hematology counter. The erythrocyte sedimentation rate was expressed in mm/h. The CRP biochemical test was performed on a Cobas c311 automatic analyzer. In group of RA patients carriers of HLA-DRB1*04 or HLA-DRB1*03 gene variants, the values of HGB and HCTwere significantlylower(p < 0.05) while the values of RDW, RDW-SD, MO, BA, MO#, BA#, ESR and CRP were statistically increased (p < 0.05) from the control group without these variants.
Structural characteristics and antioxidant activity of polysaccharide-iron complex from Glehniae Radix

ABSTRACT The preparation conditions of Glehniae Radix polysaccharide-iron complex (GLP80-Fe) were optimized and the physicochemical properties were characterized by Ultraviolet-visible spectroscopy (UV-Vis), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD), Transmission electron microscope (TEM), Thermogravimetric analyzer, and Differential scanning calorimetry (TGA-DSC), respectively. The stability and reducibility of GLP80 and GLP80-Fe were analyzed, and the monosaccharide composition was determined by gas chromatograph (GC). In vitro antioxidant activity of GLP80 and GLP80-Fe were evaluated by determining the radical (DPPH and hydroxyl radical) scavenging abilities. The results showed that the highest iron content of GLP80-Fe (15.61%±0.04) was obtained at the optimum conditions: reaction temperature was 38.0°C, reaction time was 3.0 h, FeCl3 addition was 2.9 mL and pH was 9. GLP80-Fe was a complex with β-FeOOH as the core and polysaccharides on its surface, and it was stable at pH 3 ~ 14. GC showed that the major monosaccharides were mannose (Man) and galactose (Gal) with a ratio of 1:5.15. In vitro free-radical scavenging activity of GLP80-Fe was significantly better than GLP80. The IC50 of GLP80-Fe against DPPH and hydroxyl radical were 3.785 mg/mL and 1.460 mg/mL, respectively.
The Role and Comparison of Stressful Life Events in Suicide and Suicide Attempt: A Descriptive-Analytical Study

Background: In recent years, suicide in Iran has become a growing concern. Although stressful life events (SLEs) are increasing as a global prevalence, suicide attempters (SAs) and the impact and association between suicide and SLEs are poorly understood. Objectives: This study aimed at examining the role and effect of SLEs in suicides and SAs. Methods: This descriptive-analytical study was performed during 2014 to 2016 based on 186 records (through random quota sampling) of suicidal behaviors (SBs), including 154 SAs and 32 suicide cases in Malekan County, East Azerbaijan, Iran. A valid semi-structured Life Event questionnaire (LEQ) with 43-items of common types of SLEs in the last year before SBs was used by trained interviewers through single sitting and face to face interviews. The point-biserial correlation and multiple logistic regression analysis were utilized to estimate the adjusted odds ratios and confidence intervals for suicide risk. Results: A significant correlation was found between SLEs scores and suicide (R = 0.739). Comparing SLEs types between the two groups of SAs and suicides, it was revealed that the highest odds ratios were related to financial problems (OR = 11.9; 95% CI = 4.00 - 35.85), early marriage (OR = 4.97; 95% CI = 1.68 - 14.65), exposure to new conditions (OR = 8.79; 95% CI = 1.3 - 59.22), and family conflicts (OR = 2.53; 95% CI = 1.23 - 6.53), respectively. Conclusions: SLEs are most strongly associated with committing suicide. Suicide determinants are different from SA. SLEs management by health systems is imperative to improve life skills in suicide prevention.
Context-Based Thematic Teaching Materials to Improve Elementary Students’ Learning Achievements

Contextual learning connects the content of subject matters in the classroom with the context of students’ daily lives. Elementary school learning is conducted using a thematic approach that integrates various learning contents into a theme. Thematic teaching materials in elementary schools depend on textbooks provided by the government and are limited in number. Therefore, this study aims to develop context-based thematic teaching materials to improve the learning achievements of elementary school students. In this study, the research and development method was used with the 4D model (Define, Design, Develop, and Disseminate). The product of development was validated by experts. Testing of the product was conducted twice, namely a small-group test with 8 elementary school students grade IV in SD 2 Guwo and a large-group t to determine the effectiveness of the teaching material developed. The large-group test involved 32 students of grade IV in SD Negeri 2 Kadipaten as the experimental class and 30 students of grade IV in SD Negeri 2 Guwo as the control class. The results of this study indicate that there are significant differences in learning achievements between the experimental class and the control class. The experimental class using context-based thematic teaching materials has better performance than the control class using thematic textbooks. The context-based thematic teaching material that has been developed has been proven to be able to improve student achievement. The results of this study are expected to be a reference for teachers and policymakers to develop context-based thematic teaching materials.
E-coaching Preschool Teachers to Use Simultaneous Prompting to Teach Children With Autism Spectrum Disorder

In this study, researchers examine the impact of e-coaching (including a web-based professional development [PD] portal consisting of a learning module, self-monitoring, and video feedback) on preschool teachers’ use of a simultaneous prompting (SP) procedure and the effects of SP on teaching discrete skills to their students with autism spectrum disorder (ASD). The researchers also examine maintenance and generalization effects on teachers’ and students’ behaviors. Moreover, researchers investigate the social validity of the study. They use nested multiple probe designs across four preschool teacher and student dyads to evaluate the effects of the e-coaching intervention and the SP procedure, respectively, on teachers’ and students’ behaviors. E-coaching was effective in the acquisition, maintenance, and generalization of preschool teachers’ use of the SP procedure, and the SP procedure was effective in teaching discrete skills to students with ASD. Teachers had positive opinions about e-coaching and the SP procedure. Limitations and implications for future research are discussed.
Interactive Effect of Nitrogen and Azoxystrobin on Yield, Quality, Nitrogen and Water Use Efficiency of Wild Rocket in Southern Italy

Wild rocket (Diplotaxis tenuifolia L. DC) is an emerging vegetable which market requires high-quality standards that can be obtained through appropriate cultivation techniques such as the right level of nitrogen and the application of biostimulant substances. These include strobilurins, marketed mainly as fungicides that can have complementary positive effects on the yield, quality and resources’ use efficiency of many crops. For this reason, a trial in an unheated greenhouse, in Southern Italy, to evaluate the possibility of using Azoxystrobin to improve the production of wild rocket subjected to different nitrogen inputs, was carried out. Two N levels (40 and 140 kg ha−1), Azoxystrobin-based biostimulant (Azo+) and control without Azoxystrobin (Azo−) were compared. The yield, morphological characteristics, nitrogen and water use efficiency (NUE, WUE), antioxidant activity, the content of dry matter, chlorophyll, carotenoids, phenols, and nitrates were assessed. A higher N level resulted in a 16.3% yield increase that was matched by a 12.5% reduction in NUE, 15.8, 7.3, and 16.1% increases in yield WUE (Y_WUE), biomass WUE (B_WUE), and irrigation yield WUE (IY_WUE), respectively, and a worsening of some qualitative characteristics such as a 8.5% rise in nitrates, and a decline by 11.5, 10.1, and 26.1% in the carotenoids, phenols, and antioxidant activity, respectively. Azo+ increased the yield by 10.3%, NUE by 8.9%, and Y_WUE, B_WUE, and IY_WUE, by 13.9, 9.1, and 13.8% respectively. Moreover, Azo+ improved some qualitative characteristics such as total phenols (+9.4%), chlorophyll (+15.2%), carotenoids (+9.7%), and antioxidant activity (+17.4%), while it did not affect the nitrate content. Azoxystrobin can be an additional tool available for farmers to ensure high-quality standards of wild rocket.

Nanoemulsions containing oil and aqueous extract of green coffee beans with antioxidant and antimicrobial activities

Coffee has bioactive compounds with protective effect against free radicals and antifungal and antibacterial activities that are beneficial to the health skin. This work aims to provide scientific evidence that nanoemulsions developed with oil and green coffee extract have antioxidant and antimicrobial effects. Nanoemulsions were prepared by spontaneous emulsification method using different concentrations of components (oil, extract and tensoactive) in order to optimize the preparation of formulations. The nanoemulsions presented globular morphology, negative charges, monodispersity and size around 200 nm. Two nanoemulsions, namely F7 and F16, presented characteristics of size and concentration of tensoactives more suitable for investigation regarding their antioxidant and antibacterial activities. The later assay was performed against standard strains of Staphylococcus aureus, Staphylococcus epidermidis and Escherichia coli at different nanoemulsion concentrations. The formulations proved to be inhibitors of free radicals and showed excelent antibacterial activity, demonstrating their potential for cosmetic and therapeutic applications.
The dimensional structure of transparency: A construct validation of transparency as disclosure, clarity, and accuracy in organizations

In this article, we advance research on transparency by developing and validating a measure based on recent theoretical insights about its dimensionality. We find that transparency—defined as the perceived quality of information—is a three-dimensional construct consisting of perceived information disclosure, clarity, and accuracy. Evidence shows items associated with these dimensions can be aggregated into a single transparency construct. We also find that transparency (as an aggregate construct) is distinct from neighboring constructs such as informational justice and capable of predicting perceptions of the source’s trustworthiness (ability, benevolence, and integrity). Finally, we find evidence of measurement invariance between two commonly used referents of analysis, yielding confidence in the application of the proposed measure across research settings. We discuss implications of the new measure for research on transparency, the extension of the new measure to related research traditions, and the practical application of the new measure for managers interested in constructing and appraising transparent messages.

What drives guests to misreport their experiences on Airbnb? A structural equation modelling approach

ABSTRACT The purpose of this study is to determine guest misreport sources in Airbnb reviews. Previous studies have signalled the existence of positive bias in reviews. Here we examine the relationship between misreporting and the following factors: reciprocity, attachment, tolerance threshold, strategic behaviour and social influence. The results, obtained from a sample of 815 Airbnb users who reviewed their experience on the platform, show that the strategic behaviour of guests as well as their social influence are directly related to misreporting on Airbnb. Individual attachment is indirectly related to misreporting through the tolerance threshold. This study develops and tests a structural model which explains the factors that lead guests on the platform to misreport their actual experiences.
Post-transcriptional mechanisms distinguish human and chimp forebrain progenitor cells

The forebrain has expanded in size and complexity during hominoid evolution. The contribution of post-transcriptional control of gene expression to this process is unclear. Using in-depth proteomics in combination with bulk and single-cell RNA sequencing, we analyzed protein and RNA levels of almost 5,000 genes in human and chimpanzee forebrain neural progenitor cells. We found that species differences in protein expression level was often independent of RNA levels, and more frequent than transcriptomic differences. Low-abundant proteins were more likely to show species-specific expression levels, while proteins expressed at a high level appeared to have evolved under stricter constraints. Our study implicates a previously unappreciated broad and important role for post-transcriptional regulatory mechanisms in the evolution of the human forebrain.
