Benchmarking the barriers of sustainable consumer behaviour
Authors: Sheoran Monika , Kumar Divesh 
Published: December 2020

PurposeThe earth is under massive stress due to current level of consumption which has crossed the sustaining capacity of our planet. Thus, the need of the hour is to promote sustainable production and consumption. The purpose of this study is to identify the basic barriers of sustainable consumer behaviour which are hindering the adoption of sustainable consumption.Design/methodology/approachThis article is divided into two parts. The first part consists of a literature review based on 128 articles (1995 to 2020), which are spread over a period of 25 years. Based on the literature review, nine barriers of sustainable consumer behaviour were identified and put into three categories. In the second part, fuzzy analytical hierarchy process has been used to know about the relative weight of each barrier so that benchmarking/prioritising of basic barriers of sustainable consumer behaviour can be done.FindingsThis article identifies critical barriers affecting the acceptance of sustainable electronic products. High price, a perception of no environmental impact, no benefit in personal image, lesser use by family and friends, lack of awareness about the products etc. emerged as the potential barriers which need prime attention. The relative weight of each of these barriers has also been arrived at in this article which is expected to be beneficial for policymakers to focus upon important barriers. Impact of many of these barriers can be reduced through innovative approaches and solutions.Research limitations/implicationsThis article will be helpful in future research in the field of sustainable consumer behaviour. Through the understanding of the barriers of sustainable consumer behaviour, companies, governments and industries can take suitable initiatives by modifying the policies and practices to reduce the impact of these barriers so that consumer behaviour can be made more sustainable.Originality/valueThe current article tries to identify the critical barriers to adoption of sustainable electronic products by the consumers. An extensive literature review, expert suggestions and consumer survey have been adopted to identify nine barriers. Although, multiple researches have been done in the field of sustainable consumer behaviour and adoption of sustainable electronic products, there is no research article which solely focuses on implementing Fuzzy analytical hierarchical process (AHP) approach to rank the barriers faced by consumers for adoption of sustainable electronic products. It has been concluded that high price of sustainable electronic products is the most critical barrier in adoption of sustainable consumer behaviour. Moreover, the relative ranking obtained with the help of Fuzzy AHP can be used by policymakers and organisations to promote and implement sustainability in consumer behaviour.

Published: December 2020

PurposeThe current explanations in the cyber incivility and knowledge hoarding literature suffer from two problems. The first is a lack of cogent explanation of cyber incivility and knowledge hoarding from social exchange theory (SET) perspective. The second is the unexplained attenuating propensity of justice on the connection between cyber incivility and knowledge hoarding, more specifically, interactional justice.Design/methodology/approachThis paper uses a simple random sampling method to obtain cross-sectional data from 223 employees working in IT and telecommunication service companies in Jordan. The obtained data were analyzed using partial least squares structural equation modeling (PLS-SEM) technique also known as variance-based structural equation modeling.FindingsBy applying SET theoretical lens and PLS-SEM, the authors show that cyber incivility exerts strong impact on knowledge hoarding, and interactional justice may not always function as a buffer. That is, the association between cyber incivility and knowledge hoarding is not impacted by interactional justice levels.Originality/valueThe contribution of this paper builds on the lack of practical comprehension on the association between cyber incivility and knowledge hoarding and the role played by interactional justice. Implications for theory and practice are discussed.

Authors: I. Srinivasula Reddy , Kaliveeran Vadivuchezhian 
Published: December 2020

Purpose
This paper aims to focus on the effect of normal load, sliding speed and temperature on the coefficient of friction of Al 6061-T6 alloy under dry sliding conditions.

Design/methodology/approach
Dry sliding experiments were conducted using rotary type pin on disk tribometer. Pins with 3 mm radius of contact and circular disks of 165 mm diameter were fabricated to simulate Hertzian contact configuration. Experiments were conducted by applying three different normal loads (1, 1.5 and 2 kg) and three different sliding speeds (1.25, 2 and 3 m/s) at different temperatures [room temperature (31 ± 1 °C), 60 °C, 100 °C and 150 °C].

Findings
Coefficient of friction at end of the first cycle of sliding, stabilized stage, unsteady state and steady state are reported elaborately in this study. Adhesive and abrasive wear mechanisms were observed in the dry sliding of Al 6061- T6 alloy contacts from the microscopic analysis of worn contact surfaces. The coefficient of friction was more influenced by the increase in normal load than the increase in sliding speed and temperature.

Practical implications
The results obtained from this study are significant for the design of aluminium-to-aluminium contacts in aerospace engineering and automobile engineering.

Originality/value
This study reveals the coefficient of friction of aluminium-to-aluminium (Al 6061-T6 alloy) contacts under cylinder on flat contact configuration.
Analysis of the residual stresses and deformations during the autogenous GTAW process
Authors: Savaş Atilla 
Published: December 2020

Purpose
The gas tungsten arc welding (GTAW) process is a widely used process that produces quality weldments. But the high heat generation from the GTAW arc can cause extreme temperatures as high as 20,000°C. The residual stresses and deformations are high accordingly. One of the methods for decreasing residual stresses and deformations is to change the welding pattern. In the literature, there are not so many examples of modeling dealing with welding patterns. This paper aims to investigate the influence of welding patterns on the deformations.

Design/methodology/approach
In this work, back-stepping patterns and partitioning of the weld line were investigated and the distortions and residual stresses were calculated. By doing this, temperature-dependent thermophysical and thermo-mechanical material properties were used. The temperature distribution and deformation from experiments with the same welding conditions were used for validation purposes.

Findings
Seven different welding patterns were analyzed. There is only one pattern with a single partition. There are three patterns investigated for both two and three partitioned weldings. The minimum deformation and the optimum residual stress combination is obtained for the last pattern, which is a three partitioned and diverging pattern.

Originality/value
The most important aspect of this paper is that it deals with welding patterns, which is not much studied beforehand. The other important thing is that the structural part and the thermal part of the simulation were coupled mutually and validated according to experiments.

Published: December 2020

SummaryClose associations between single‐celled marine organisms can have a central role in biogeochemical processes and are of great interest for understanding the evolution of organisms. The global significance of such associations raises the question of whether unidentified associations are yet to be discovered. In this study, fluorescence‐activated cell sorted photosynthetic picoeukayote (PPE) populations and single cells were analysed by sequencing of 16S rRNA genes in the oligotrophic North Pacific Subtropical Gyre. Samples were collected during two cruises, spanning depths near the deep chlorophyll maximum, where the abundance of PPEs was highest. The association between the widespread and significant nitrogen (N2)‐fixing cyanobacterium, UCYN‐A and its prymnesiophyte host was prevalent in both population and single‐cell sorts. Several bacterial sequences, affiliating with previously described symbiotic taxa were detected but their detection was rare and not well replicated, precluding identification of novel tightly linked species‐specific associations. Similarly, no enrichment of dominant seawater taxa such as Prochlorococcus, SAR11 or Synechococcus was observed suggesting that these were not systematically ingested by the PPE in this study. The results indicate that apart from the UCYN‐A symbiosis, similar tight species‐specific associations with PPEs are unusual in the oligotrophic ocean.

AbstractBackgroundEndometriosis is a multifactorial pathology dependent on intrinsic and extrinsic factors, but the immune deregulation seems to play a pivotal role. In endometriosis‐associated infertility, this could raise the benefit of immunomodulatory strategies to improve the results of ART. In this review, we will describe (1) sera and peritoneal fluid cytokines and immune markers; (2) autoantibodies; and (3) immunomodulatory treatments in endometriosis with infertility.MethodsThe literature research was conducted in MEDLINE, Embase, and Cochrane Library with the following keywords: “endometriosis”, “unexplained miscarriage”, “implantation failure”, “recurrent implantation failure » and « IVF‐ICSI », « biomarkers of autoimmunity”, “TNF‐α”, “TNF‐α antagonists”, “infliximab”, “adalimumab”, “etanercept”, “immunomodulatory treatment”, “steroids”, “intralipids”, “intravenous immunoglobulins”, “G‐CSF”, “pentoxyfylline”.ResultsSeveral studies analyzed the levels of pro‐inflammatory cytokines in sera and peritoneal fluid of endometriosis‐associated infertility, in particular TNF‐α. Various autoantibodies have been found in peritoneal fluid and sera of infertile endometriosis women even in the absence of clinically defined autoimmune disease, as antinuclear, anti‐SSA, and antiphospholipid autoantibodies. In few uncontrolled studies, steroids and TNF‐α antagonists could increase the pregnancy rates in endometriosis‐associated infertility, but well‐designed trials are lacking.ConclusionEndometriosis is characterized by increased levels of cytokines and autoantibodies. This suggests the role of inflammation and immune cell deregulation in infertility associated with endometriosis. The strategies of immunomodulation to regulate these immune deregulations are poorly studied, and well‐designed studies are necessary.

AbstractPurposeVasoproliferative tumours (VPT) are a rare but benign entity that can lead to severe visual acuity deterioration. There is no standard of care, and depending on the degree of clinical features, including tumour size and dissemination, visual acuity and subretinal fluid, treatment options include observation, cryotherapy and brachytherapy. Particularly in larger tumours, brachytherapy has advantages over other options, although higher radiation doses and the need for surgical application are disadvantages of this otherwise effective treatment option. CyberKnife radiosurgery might represent an alternative therapeutic option as no surgical intervention is needed and radiation doses are lower.MethodsAll patients diagnosed with vasoproliferative tumors who were treated with CyberKnife radiosurgery with a minimum follow‐up time of 12 months were included in this case series. We recorded visual acuity, number of lesions, central retinal thickness with optical coherence tomography (OCT) and reflectivity using A‐scan standardizes echography every three months.ResultsA total of four patients with a median age of 34 years (range: 24 – 51) who were observed over an average of 26.5 months (range: 17 – 49 months) matched our inclusion criteria. We appreciated stabilization or increase in visual acuity in all four patients and a regression in tumour thickness with subsequent increase in internal reflectivity as a marker of increasing fibrosis.ConclusionWe observed good visual and functional outcome following CyberKnife therapy for VPT. We believe that further studies should be pursued to evaluate CyberKnife therapy for the treatment of VPT not treatable with cryo‐ or lasertherapy.

AbstractDiscrimination of Philadelphia‐negative myeloproliferative neoplasms (Ph‐MPNs) from reactive hypercytosis and myelofibrosis requires a constellation of testing including driver mutation analysis and bone marrow biopsies. We searched for a biomarker that can more easily distinguish Ph‐MPNs from reactive hypercytosis and myelofibrosis by using RNA‐seq analysis utilizing platelet‐rich plasma (PRP)‐derived RNAs from patients with essential thrombocythemia (ET) and reactive thrombocytosis, and CREB3L1 was found to have an extremely high impact in discriminating the two disorders. To validate and further explore the result, expression levels of CREB3L1 in PRP were quantified by reverse‐transcription quantitative PCR and compared among patients with ET, other Ph‐MPNs, chronic myeloid leukemia (CML), and reactive hypercytosis and myelofibrosis. A CREB3L1 expression cutoff value determined based on PRP of 18 healthy volunteers accurately discriminated 150 driver mutation–positive Ph‐MPNs from other entities (71 reactive hypercytosis and myelofibrosis, 6 CML, and 18 healthy volunteers) and showed both sensitivity and specificity of 1.0000. Importantly, CREB3L1 expression levels were significantly higher in ET compared with reactive thrombocytosis (P < .0001), and polycythemia vera compared with reactive erythrocytosis (P < .0001). Pathology‐affirmed triple‐negative ET (TN‐ET) patients were divided into a high– and low–CREB3L1‐expression group, and some patients in the low‐expression group achieved a spontaneous remission during the clinical course. In conclusion, CREB3L1 analysis has the potential to single‐handedly discriminate driver mutation–positive Ph‐MPNs from reactive hypercytosis and myelofibrosis, and also may identify a subgroup within TN‐ET showing distinct clinical features including spontaneous remission.
Immunological interpretation of minipuberty: Minipuberty as the driving force of sexual dimorphism in the immune response
Authors: Karaoglan Murat , Nacarkahya Gulper 
Published: December 2020

AbstractBackground/ObjectiveAlthough the physiology of minipuberty is well established, it is not fully explained why it occurs. It has been suggested that minipuberty contributes to the development of reproductive organs, somatic growth, cognitive/behavioural and sex‐specific brain development. Given the well‐known trade‐off between the reproductive/endocrine and immune systems in adults, the immunological approach to minipuberty, which is characterized by transient activation of the hypothalamo‐pituitary gonadal (HPG) axis, seems to be ignored.This study focused on the relationship of the lymphocyte subsets with gonadotrophin and sex hormones during the minipuberty.Materials and MethodsA total of 121 newborns (58 male) were included in this cross‐sectional study. The hormone and lymphocyte subsets studied were as follow: follicle‐stimulating hormone (FSH), luteinizing hormone (LH) estradiol (E), testosterone (T), CD19, CD16/56, CD3, CD3/CD4, CD3/CD8 and HLA‐DR as lymphocyte activation marker.ResultsThe mean FSH levels were higher in females (15.15 ± 10.12 mIU/ml vs, 2.61 ± 1.74 mIU/ml) and LH in males (5.80 ± 2.51 mIU/ml vs. 1.91 ± 12.89 mIU/ml) (P < .001 for each). The mean percentages of the CD3/CD4 levels were higher in females (54.61 ± 6.70% vs. 51.17 ± 6.77%) and CD3/CD8 in males (21.49 ± 4.82% vs. 17.31 ± 3.66%) (P < .001 for each). In the females, the mean FSH levels negatively correlated with CD3/CD4 (rFSH‐CD3/CD4 = −0.423, P = .001) and positively correlated with CD3/CD8 (rFSH‐CD3/CD8 = 0.311, P = .013). In the males, LH positively correlated with CD3/CD4 (rLH‐CD3/CD4 = 0.406, P < .001) and negatively correlated with CD3/CD8 (rLH‐CD3/CD8 = −0.486, P < .001).ConclusionThis study showed that the mean CD3/CD4 levels were higher in female and CD3/CD8 in male newborns, indicating that there was a sexual dimorphism in favour of immunostimulant in females and immunosuppressor components of immune response in males during the minipuberty. These interactions point to sex‐specific trade‐off between reproductive/endocrine and immune systems, which it reflects the an investment favouring in the reproductive system against the immune response during minipuberty, which is critical period for adult fertility, especially in males.

AbstractThe aim of present study was to explore whether 2‐cyano‐3, 12‐dioxooleana‐1, 9‐dien‐28‐oic acid (CDDO)‐ethylamide (CDDO‐EA) attenuates cerebral ischemic injury and its possible mechanisms using a middle cerebral artery occlusion (MCAO) model in C57BL/6 mice. Our results showed that intraperitoneal injection (i.p.) of CDDO‐EA (2 and 4 mg/kg) augmented NFE2‐related factor 2 (Nrf2) and heme oxygenase‐1 (HO‐1) expression in ischemic cortex after MCAO. Moreover, CDDO‐EA (2 mg/kg, i.p.) significantly enhanced Nrf2 nuclear accumulation, associated with increased cytosolic HO‐1 expression, reduced neurological deficit and infarct volume as well as neural apoptosis, and shifted polarization of microglia/macrophages toward an antiinflammatory M2 phenotype in ischemic cortex after MCAO. Using an in vitro model, we confirmed that CDDO‐EA (100 μg/mL) increased HO‐1 expression and primed microglial polarization toward M2 phenotype under inflammatory stimulation in BV2 microglial cells. These findings suggest that a novel Nrf2 activator CDDO‐EA confers neuroprotection against ischemic injury.

Published: December 2020

AbstractIntroductionCurrently, there are no studies that analyse the changes in the cardiac venous system that are dependent on the phase (RR interval) of reconstruction. The aim of the study was to assess the size of the coronary sinus at two measurement sites depending on the phase of the heart cycle.MethodsFifty patients were included. Cardiac computed tomography was performed in all of the patients due to a suspicion of coronary artery disease (typical indications) using a dual‐source Siemens Somatom Force scanner. The “MM reading” presets were used to measure the coronary sinus ostium (measurement 1) and the coronary sinus trunk, which is close to the great cardiac vein (measurement 2) in millimetres. All of the calculations were performed on axial scans using 0%–100% and a 256 × 256 matrix.ResultsThe largest CS was found at the 30%, 40% and 50% RR interval—this phenomenon occurred in 37 of the 50 cases (74%). The CS was largest in the 30% phase (9/50 cases; 18%), in the 40% phase (17/50 cases; 34%) and in the 50% phase, and it was the largest in 11 of the 50 cases (22%). There were also no gender‐related differences.ConclusionsThe size of the coronary sinus varies with the phase of the heart cycle. At the 40% phase, it is largest in most cases.

AbstractBackgroundDespite advances in critical care for acute respiratory distress syndrome (ARDS), some survivors in the acute phase are unable to wean from extracorporeal membrane oxygenation (ECMO) or mechanical ventilation. To date, little is known regarding whether lung transplantation confers a survival benefit for irreversible ARDS.MethodsThis retrospective study was conducted using the United Network for Organ Sharing database (May 2005–December 2018). Patients with restrictive lung disease were divided into two groups: patients with and without ARDS. Propensity score matching identified recipients without ARDS for the control group.ResultsA total of 63 patients with ARDS were waitlisted for lung transplantation, while 39 received a lung transplant after a median waitlist duration of 8 days. Seventy‐eight patients were matched as controls. In the ARDS group, the median age was 30 years, and the median lung allocation score was 88.4. Among the 39 recipients, 30 (76.9%) received ECMO support prior to transplantation. Lung transplantation for ARDS and restrictive lung disease showed similar 90‐day (87.2% vs. 88.5%, p = .80), 1‐year (82.1% vs. 85.9%, p = .52), and 3‐year (69.2% vs. 65.4%, p = .94) survival rates.ConclusionsLung transplantation provides acceptable outcomes in selected patients with irreversible ARDS.
