Service gifts, collective social connection and reciprocity

This study aims to investigate the process of service gifting (i.e. unexpected upgrades or benefits) and examine why service gifts do not always result in firm-beneficial reciprocal behaviors from consumers. ,Through a series of three studies including both scenario-based and game-theory-based experiments, this research proposes and empirically validates a conceptual model that examines the effect of service gifts on firm-beneficial reciprocal behaviors, and the role of collective social connection and norm of positive reciprocity (NPR) in this process. ,The findings of this research show that the consumer’s feelings of collective social connection mediate the link between the provision of service gifts and firm-beneficial outcomes. Furthermore, an individual’s adherence to NPR moderates this process. Specifically, individuals with a strong adherence to NPR do not display increases in collective social connection following the receipt of a service gift. Those who are low in NPR follow the expected pattern of increased collective social connection leading to reciprocation. ,Future research may further generalize the model to other situations such as high vs low context cultures. Longitudinal field experiments can be used to further investigate collective versus relational social connection, which can be either a by-product or a primary benefit derived from service delivery. ,The results of this research reveal the critical role of collective social connection which has been largely ignored in service gifting research. It encourages managers to use service gifting to directly boost consumers collective social connection. Furthermore, it offers managers insight into why service gifts do not always result in firm-beneficial outcomes because of the moderating role of NPR. ,The roles of social connection and the norm of reciprocity have been under-studied in both theoretical and empirical work on service gifting. This paper demonstrates that, contrary to traditional thought, those typically expected to reciprocate the most (i.e. high in NPR) may not realize increased collective social connection leading to reciprocation following receipt of a service gift.
Omalizumab for Treatment of Pediatric Atopic Dermatitis:A Systematic Review of Randomized Controlled Trials

The design of Omalizumab (Xolair; Novartis) is based on binding to IgE, limiting the activation of mast cells and the subsequent release of inflammatory mediators. In the current study, we aim to conduct a systematic review of Omalizumab for the treatment of pediatric atopic dermatitis (AD). For that, a systematic electronic database search was conducted for relevant studies published from inception till 4th July 2020 in nine databases. Finally, we included four studies for this systematic review and meta-analysis. Our results showed that free IgE dropped from 963 IU/ml to 923 IU/ml in the placebo group while it dropped dramatically from 847 to 9.8 in the Omalizumab group. Moreover, Omalizumab decreased serum IgE levels from 16007 IU/ml to 6641 IU/ml. Furthermore, a significant decrease in the SCORAD index was observed from the two included RCTs (p < 0.05), after the administration of Omalizumab compared to the placebo group. For safety assessment, two studies did not report Omalizumab adverse events and one reported no serious adverse events. In conclusion, Omalizumab showed promising efficacy and reasonable safety index in the treatment of AD in the pediatric population.
Botanical Composition and In Situ Dry Matter Degradability of Legume- Grass Mixture Pasture Fertilized with Different Amounts of Nitrogen

This study was conducted to determine the effects of different nitrogen (N) fertilizer levels on botanical composition, dry matter (DM) yield, chemical composition, in situ ruminal DM and NDF degradability and net energy lactation (NEL) of a native legume-grass mixture pasture. Field and degradability trials were arranged in a Complete Randomized Block Design with three replicates. Pasture was fertilized at six levels of N fertilizer (ammonium nitrate, N0, N50, N100, N150, N200 and N250 kg/ha). Three rumen cannulated Holstein Friesian heifers (3-4 year old) were used. Feed samples were incubated for 0, 8, 12, 24, 36, 48, 72 and 96 h. Application of nitrogen fertilizer results indicated that nitrogen fertilizer decreased the legumes ratio (LR) of pasture, approximately 22.4%, Although N fertilizer increased the grass ratio (GR) of pasture approximately 55.8%. Dry matter (DM), Net energy lactation (NEL, Mcal/kg) and ash contents of pasture were increased by increasing N fertilizer level. However, when N fertilizer level increased acid detergent fiber (ADF) concentration of pasture decreased. Application of the different rate of nitrogen fertilizer had no effect on in situ rumen degradability of DM and NDF of pasture. It was also found that there was the significant positive relationship between effective NDF degradability at 48 h. rumen incubation period and different level of N fertilizer. In addition, it was determined that there was a linear and quadratic positive relationship between DM yield and different nitrogen doses. In conclusion, different rates of nitrogen application changed botanical composition, decreased ADF content and increased NEL and effective rumen degradability of neutral detergent fiber (EDNDF 48 h.) of pasture.
Genetic diversity analysis in bread weat (Triticum aestivum L.) under Gangetic Alluvium Zone of West Bengal

Forty-nine genotypes of bread wheat (Triticum aestivum L.) were screened at District farm, AB Block, B.C.K.V. , Kalyani, Nadia, West Bengal during Rabi season for two years, i.e. 2015-2016 and 2018-2019 following Randomized Block Design with two replications to study genetic diversity following the Mahalanobis D2 statistics and principal component analysis. The highest contribution towards total divergence was yield plant-1 followed by the number of grains spike-1, plant height, weight of grains spike-1 and the test weight. The maximum inter-cluster distance was observed between cluster IX and I (86.392), followed by clusters VIII and IX (82.829) indicating that the genotypes being represented in these clusters were distantly related. Therefore, any two genotypes selected from these two clusters may be utilized in crossing programs to synthesis potential high yielding genotypes. Principal component analysis (PCA) extracted 5 principal components explaining 80% to genetic variation. The PCA suggested that the genotypes are highly diverse.
Depression and Cognitive Levels in Health Workers With Night Shifts

The study aims to analyse the presence of depressive symptoms correlated to memory and cognitive deficits in night-shift healthcare personnel working in the emergency wards of a Sicilian hospital, and examines the repercussions on health and safety in the workplace. A psycho-diagnostic protocol including a subtest of the Weschler Adult Intelligence Scale/WAIS-IV (PRI, WMI, PSI) and the Beck Depression Inventory (BDI) was administered to the sample of 50 subjects (25 doctors and 25 nurses) selected by taking inclusion and exclusion criteria into account. The results showed that the whole sample displayed normal levels in terms of perceptual reasoning index, image perception, the ability to isolate figures from the background, eye-motor coordination and non-verbal reasoning. Working memory index and processing speed index – indicative of concentration, manipulation, short-term memory, processing speed, selective attention and spatial orientation – were meanwhile found to be compromised to a higher percentage among nurses. The Beck Depression Inventory denoted a greater presence of depressive symptoms in nurses than doctors, associated with lower levels of WMI and PSI.

The proposed triglyceride model was developed using Gaussian 09 and computational analyses were carried out using Density functional theory (DFT) method. Based on geometric optimization, the average bond length between C-C bond, C=C bond, C-H bond, C-O bond and C=O bond was measured as 1. 53Å, 1. 33Å, 1. 09Å, 1. 43Å and 1. 23Å respectively. Average dipole moment of the triglyceride molecule was measured as 1.3010 Debye while electronic dislocation was noted in X+Z direction. In addition, the overall molecular energy was found to be - 2522.7425 a.u. and optimization energy as -58.95 kJ/mol. Also, vibrational frequencies were analysed using the IR spectrum whereas electrostatic potential were mapped for the triglyceride molecule.
Comparison of Product Life Cycle Cost Estimating Models Based on Neural Networks and Parametric Techniques—A Case Study for Induction Motors

The cost estimation of a product’s life cycle is a key factor in the product design process. The research is based on an innovative model of artificial neural networks (ANNs) compared to a parametric estimation. Introducing modern elements of information technologies in the area of cost estimation for a production company is a vital element of its sustainability in the era of Industry 4.0. The presented modern product life cycle cost estimation tool in the form of ANN is a reliable source of forecast that is the basis for the product life cycle cost reduction program, which is a crucial element of sustainability. Research shows that ANNs are a viable alternative to parametric cost estimation. The percentage error between estimated and historical cost values is 8.05 times lower for ANN than for the parametric approach. ANN is an adequate cost estimation model for technologically complex products. The second contribution is using technical specifications required by the customer directly to estimate the cost of a product’s life cycle automatically. This can translate both into a reduction of the time needed to provide information to the client and the workload of engineers.
Experimental evidence for conservation conflict interventions: The importance of financial payments, community trust and equity attitudes

1. Conflicts between the objectives of agricultural production and conservation are becoming increasingly complex. Of vital importance to the success of conflict in terventions is a detailed understanding of how stakeholders react to management interventions as well as the influence of interacting social and political factors. 2. Across Europe, goose populations have increased considerably, leading to widespread impacts on agriculture and significant conflicts between different stakeholder groups. We used a novel experimental game to understand farmer preferences regarding the design of goose conflict
Machine-Learning Assisted Laser Powder Bed Fusion Process Optimization for AlSi10mg: New Microstructure Description Indices and Fracture Mechanisms

Abstract In this study, a machine-learning approach based on Gaussian process regression was developed to identify the optimized processing window for laser powder bed fusion (LPBF). Using this method, we found a new and much larger optimized LPBF processing window than was known before for manufacturing fully dense AlSi10Mg samples (i.e., relative density ≥ 99%). The newly determined optimized processing parameters (e.g., laser power and scan speed) made it possible to achieve previously unattainable combinations of high strength and ductility. The results showed that although the AlSi10Mg specimens exhibited similar Al-Si eutectic microstructures (e.g., cell structures in fine and coarse grains), they displayed large difference in their mechanical properties including hardness (118 - 137 HV 10), ultimate tensile strength (297 - 389 MPa), elongation to failure (6.3 - 10.3%), and fracture toughness (9.9 - 12.7 kJ/m2). The underlying reason was attributed to the subtle microstructural differences that were further revealed using two newly defined morphology indices (i.e., dimensional-scale index Id and shape index Is) based on several key microstructural features obtained from scanning electron microscopy images. It was found that in addition to grain structure, the sub-grain cell size and cell boundary morphology of the LPBF fabricated AlSi10Mg also strongly affected the mechanical properties of the material. The method established in this study can be readily applied to the LPBF process optimization and mechanical properties manipulation of other widely used metals and alloys or newly designed materials.
Stability of Vitamin C in Selected Vegetables under Different Storage Conditions

Vegetables and fruits are natural source of biological antioxidants. Vitamin C is an essential micronutrient which plays an important role in human health. Its deficiency results in a disease referred to as scurvy in humans. The objective of this study was to determine the amount of vitamin C in some selected vegetables procured from local market in Hyderabad city. In addition, the effect of storage conditions (refrigerated temperature (4°C) and room temperature) on percentage reduction of vitamin C in these vegetables was also analyzed on day 2, 4 and 6 of storage period. Results revealed that there was a reduction of vitamin C content in vegetables stored both at refrigerated temperature (4°C) and room temperature. However, the reduction was higher in vegetables stored at room temperature as compared to those stored at refrigerated temperature (4°C). Accepted: 31 July 2017 Available Online: 06 August 2017
DNA Authentication of Asian Redtail Catfish Hemibagrus nemurus from Musi and Penukal River, South Sumatra Indonesia

Asian Redtail Catfish (Hemibagrus nemurus) is highly economic important catfish in South Sumatra. Investigating DNA authentication is of importance for species conservation and breeding selection. Cytochrome C Oxidase subunit I is one of mitochondrial DNA markers used for species barcoding in freshwater, brackishwater and marine fish. This research aims to explore the use of COI gene for species barcoding, constructing phylogenetic tree of Asian Redtail Catfish (ARC). The methods used in the research consisted of DNA extraction, PCR (Polymerase Chain Reaction) amplification and sequencing mtDNA COI gene of ARC obtained from Musi and Penukal Rivers (South Sumatra). A 572 and 596 base pairs of partial coding sequences were obtained representing each river. Phylogenetic analyses indicated that ARC was at the same cluster from Bagridae family, and different cluster from others catfish, Pangasius sp and Oreochomis niloticus. Further study using more species of Bagridae and habitat are needed to investigate the diversity of DNA from South Sumatra water resources
University teaching and learning in a time of social distancing: A sociocultural perspective

ABSTRACT The emergence of the novel coronavirus disease (COVID-19) has challenged every aspect of our “normal” lives. COVID-19 requires us to make behavioral and attitudinal changes to coexist with the coronavirus. Universities have been affected substantially, and online teaching and learning have become the “new normal. ” The strategies to achieve this “new normal” and how they are received depend on the sociocultural context. This preliminary qualitative inquiry explores how, during the early stage of the COVID-19 pandemic in Japan, university teaching and learning were maintained and social distancing became a learning opportunity. The voices of first-year graduate students in this inquiry enable us to understand the dynamics of their responses and show their resilience, particularly their ability to turn challenges into creative opportunities. The implications are that shared values and beliefs will help us to get through this crisis together, and collective action will help us to continue to move forward.
Lipopolysaccharide Receptor, Toll -Like Receptor 4, Mediated Signaling Pathways Leading to Cyclooxygenase-2 Expression in Murine Macrophages.

Genetic evidence indicating that Toll-like receptor 4 (TLR4) is the lipopolysaccharide (LPS) receptor in mice was reported. However, biochemical evidence that murine TLR4 confers LPS responsiveness has not been convincingly demonstrated. Inducible cyclooxygenase (COX-2) is selectively expressed in LPSstimulated macrophages in part mediated through activation o f NFkB. Thus, we determined whether murine TLR4 confers LPS responsiveness as evaluated by activation of NFkB and COX-2 expression. Expression of the constitutively active form (ATlr4) o f TLR4 in murine macrophage cell line (RAW 264.7) is sufficient to activate NFkB and COX-2 expression and to stimulate prostaglandin E2 synthesis. The truncated form [ATlr4 (P712H)] of the missense mutant Tlr4 (P712H) found in LPShyporesponsive mouse strain (C3H/HeJ) inhibits LPS-induced NFkB activation and COX-2 expression. Inability of ATlr4 (P712H) to activate NFkB and to induce COX-2 expression is rescued by a constitutively active adaptor protein (MyD88) which interacts directly with the cytoplasmic domain o f TLR proteins. Furthermore. MyD88 is co-immunoprecipitated with the wild type ATlr4, but not with ATlr4 (P712H) mutant. Together, these results indicate that TLR4 confers LPS responsiveness in RAW 264.7 cells, and suggest that hyporesponsiveness o f C3H/HeJ mice to LPS is due to disruption o f TLR4-mediated signaling pathways resulting from inability of the mutant TLR4 (P712H) to interact with MyD88. In addition, the involvement of Lyn, Src-protein tyrosine kinase family, in LPS-induced signaling pathways leading to COX-2
Gene Flow Constrains and Facilitates Genetically Based Divergence in Quantitative Traits

Theory predicts that gene flow will decrease phenotypic differences among populations. Correlational studies have in some cases documented constraining effects of gene flow on phenotypic divergence and/or have also provided evidence for local differentiation despite high gene flow. However, correlative studies are unable to evaluate how gene flow affects genetically based phenotypic divergence or the extent to which gene flow constrains adaptive divergence. Translocation experiments using Trinidadian guppies provided an opportunity to test the effects of new gene flow on quantitative traits in native recipient populations. We measured a suite of traits in guppies reared in common garden environments before and multiple generations following gene flow from guppies that originated from a different environment. We interpreted our results in light of a priori predictions based on evolutionary theory and extensive background information about guppies and our focal populations. Although we could not include a spatiotemporal control that would allow us to be certain that the observed changes were directly caused by gene flow, we found that post-gene flow populations showed genetically based shifts in most traits. Whether traits shifted in predicted adaptive directions or whether they became more or less similar to the source population depended on the trait and initial conditions of the population. Our study provided a rare opportunity to test how recent gene flow affects genetically based changes in traits with known adaptive significance, and our results attest to the complex interactions between gene flow and selection.
Distributed cognition and “Course of action”

The ‘distributed cognition’ research program, initiated by Edwin Hutchins, has contributed to the development of the ‘course of action’ research program from 1987 to the present day. Edwin Hutchins having recently recognized the close relationship between his latest research, developed in terms of embodied and distributed cognition, and that on the enaction paradigm, of which this ‘course of action’ research program is a part, the question now arises of the definition of an “augmented ‘course of action’ research program”. In relation to this enaction paradigm, such a program should go into greater depth and provide a new synthesis of the ‘distributed cognition’ research program’s past contributions to the ‘course of action’ research program and integrate its new contributions. This in-depth analysis, synthesis and renewal of the contributions to the ‘course of action’ research program are facilitated by the mutual contribution and addition of different theoretical and methodological results obtained by the two research programs over recent decades. In this paper we will present our personal view of the answer to this question.
Development of a completely recyclable glass fiber‐reinforced epoxy thermoset composite

Stimulated by the growing demand for more sustainable polymer systems, experiments were performed to develop completely recyclable epoxy‐based thermoset composite materials involving the separation, recovery, and complete reuse of both components of the composite, the resin and the fibers. In this study, a possibility to design such composites by incorporation of reversible chemistry for dedicated repair and recycling is demonstrated. Relying on Diels–Alder (DA) adducts located on the cross‐links between the polymeric chains, uncross‐linking the thermoset via the reverse DA reactions becomes possible. The network breaks up at elevated temperatures in shorter segments, which can be solubilized in solvents like acetic acid, butan‐1‐ol, or toluene. Specific processes for each of these solvents were developed to recover the resin and fibers with virtually unchanged properties. Both components were used in a second manufacturing step to produce recycled composites which display properties comparable with the original composites.
Relative Contribution of Reading Fluency and Vocabulary Knowledge in Predicting Korean EFL Learners’ Reading Comprehension

Despite the growing body of research evidence validating the Simple View of Reading (SVR) which highlights decoding and listening comprehension abilities as the prominent contributors of reading comprehension, there have been concerns regarding the need to augment it to consider other relevant variables. For advanced readers whose decoding skills are fully developed, an alternate code-related skill such as reading fluency needs to be considered. This is especially pertinent for second language readers whose phonics skills tend to be superior to their language abilities. Another concern has not only been with the need to consider vocabulary knowledge as an independent predictor, but also with the need to discern the contribution of both quantity and quality of vocabulary knowledge. Although there have been numerous studies showing the significant relationship between reading comprehension and both vocabulary breadth and depth, these have been rarely looked at discretely in the SVR framework. This study investigated the relative contribution of vocabulary breadth, vocabulary depth, and reading fluency to secondary Korean EFL learners’ reading comprehension within an augmented SVR model. The findings indicated that although all of the considered predictors were significantly related to their reading comprehension, only listening comprehension and vocabulary depth demonstrated significant unique contribution.
