Authors: Obaidat Yasmeen Taleb , Barham Wasim , Abu libdeh Rawan 
Published: October 2022

PurposeThe main aim of this study is to examine the behavior of reinforced concrete short columns strengthened using longitudinal near surface mounted (NSM)-carbon fiber reinforced polymer (CFRP) strips.Design/methodology/approachA full 3D-finite element (FE) model was developed using ABAQUS in order to conduct the analysis. The model is first validated based on experimental data available in the literature, and then the effect of concrete compressive strength, number of CFRP strips that are used and the spacing between them were taken in consideration for both concentric and eccentric loading cases. The parametric study specimens were divided into three groups. The first group consisted of unstrengthened columns and served as control specimens. The second group consisted of columns strengthened by longitudinal CFRP strips at two opposite column faces.FindingsThe results of this study are used to develop interaction diagrams for CFRP-strengthened short columns and to develop best-fit equations to estimate the nominal axial load and moment capacities for these strengthened columns. The results showed that the specimens that were strengthened using more longitudinal CFRP strips showed a significant increase in axial load capacity and a significant improvement in the interaction diagram, especially at large load eccentricity values. This result can be justified by the fact that longitudinal strips effectively resist the bending moment that is generated due to eccentric loading. Generally, the process of strengthening using longitudinal strips only has a reasonable effect and it can be typically considered an excellent choice considering the economic aspect when the budget of strengthening is limited.Originality/valueThis research aims at studying the performance of strengthened rectangular reinforced concrete short columns with CFRP strips using FE method, developing interaction diagrams of strengthened columns in order to investigate the effect of different parameters such as compressive strength (20, 30 and 40 MPa), number of CFRP strips (1, 2, 3 and 4) and the spacing between CFRP strips in terms of the ratio of CFRP center point distance to column outside dimension ratio (0.60, 0.70 and 0.80) on the behavior of strengthened RC columns and improving empirical formulas to predict the nominal axial load and moment capacities of strengthened RC columns. These parameters that directly affect short column load carrying capacity are presented in ACI-318 (2014).

Published: October 2022

PurposeThis research aims to provide a predictive model assessment on the effect of information sharing on fresh produce supply chain (FPSC) performance during the COVID-19 pandemic by incorporating information quality as an important part of information sharing, as well as cognitive and affective appraisals as part of a social learning process (mediators) into the model.Design/methodology/approachAn online survey was conducted on 197 small fresh produce (fruits and vegetables) retailers in Indonesia during the COVID-19 pandemic. The data were analysed using Partial Least Squares Structural Equation Modeling (PLS-SEM) particularly PLSpredict supported by SmartPLS 4 software.FindingsThis research reveals that information sharing is positively and significantly associated with information quality and that the two constructs are not directly associated with FPSC performance. The path analysis suggests that the effect of information sharing on FPSC performance is fully mediated by cognitive and affective appraisals to the information-sharing activity. It also suggests that the effect of information quality on FPSC performance is fully mediated by affective rather than cognitive appraisal. This model shows a high predictive power and highlights the pivotal role of the learning process during the COVID-19 pandemic.Originality/valueThis research is the first to employ a predictive model assessment in PLS-SEM to empirically predict the effect of information sharing on FPSC performance using a social learning perspective, particularly in the context of the COVID-19 pandemic.
Sense of belonging among people outside of working life in Finland
Authors: Turunen Elina , Hiilamo Heikki 
Published: October 2022

PurposeFor social inclusion, it is necessary to have a sense of belonging to society, whether having a job or not. Experience of belonging means feeling a part of something beyond oneself. It can be a place, a moment, a situation or a group of people.Design/methodology/approachThe authors study how unemployed people experience their place in a society; more specifically, the authors analyse which emotions and affects encourage (and discourage) the sense of belongingness among the unemployed. Emotions and affects were examined in 10 focus group interviews collected in Finland between 2016 and 2017. The data was analysed using qualitative content analysis.FindingsThe results demonstrate that sense of belonging is enhanced by affects such as being needed, being accepted and experiencing equal treatment. To achieve these affects, promotion of social contacts, participation and contribution to the common good are important.Originality/valuePrevious studies have mostly ignored the role of emotions and affects in the experience of unemployment. The findings emphasize the importance of emotions and affects in promoting and eroding the sense of belonging among unemployed people.

Authors: Gunduz Songur Aysegul , Turktarhan Gozde , Cobanoglu Cihan 
Published: October 2022

PurposeThe aim of this research, which is based on a literature review and bibliometric analysis, is to reveal the development of green technologies in hotels, based on the articles published in tourism and hospitality journals between 1999 and 2020.Design/methodology/approachBased on five conditions and five databases, 64 journal papers were retrieved and reviewed. Among the surveyed publications pertinent to the eco-friendly/green technology practices at hotels, the majority focus was on the need for eco-friendly/green technology practices at hotels and the schemes implemented to achieve sustainable development.FindingsThe research findings especially from the last decade report that today's guests generally prefer green hotels based on their increased awareness of environmental degradation and an ever-growing need for conservation and sustainability.Practical implicationsThe environmental responsibility which is inherent in the hospitality and tourism industry due to the environmental burden generated by the combined effect of both industries on Mother Earth, brings forth a substantial sense of commitment on the part of hotel companies. In that regard, a set of corporate initiatives in the form of green technology practices are implemented by hotels, toward the development of new product and service offerings, management of processes and corporate policy formation.Originality/valueThis research focuses on green technologies aimed at sustainability in the field of accommodation and tourism, consisting of a systematic literature search on the subject. It is important in the way that it provides a general overview to researchers in terms of the theoretical implications of green technologies while also offering a road map with respect to green technology applications to the practitioners of the field.
The process of decentralization through mobile instant messaging (MIM): a case study of event management in an organization
Authors: Ahmad Nur Syazwani , Bahri Shamshul , Fauzi Ali 
Published: October 2022

Purpose
This study aims to explore how the use of mobile instant messaging (MIM) in an organization has led to the decentralization of authority.

Design/methodology/approach
To achieve this aim, a study was conducted on a case site that had used MIM extensively to manage an event.

Findings
This study found that communication technology such as MIM can shift more authority to the lower-level committees through the processes of formation, delegation, control and dissolution.

Originality/value
The role of information systems and technology in affecting a decentralization process has been largely understudied. Additionally, the effect of communication technologies such as MIM on a decentralization process has been largely ignored. Therefore, this study theorizes the role of MIM in managing an event and how the technology has decentralized more authority from the top management to the lower-level committees.
Role of celebrity credibility on banking service providers
Authors: Singh Ramendra Pratap 
Published: October 2022

PurposeThis study examines the role of celebrity credibility in fostering loyalty and long-term commitment toward the financial service provider (banking services in this study) through the development of trust in the service provider. The relationship combines the commitment-trust theory, the source credibility, and the meaning transfer model.Design/methodology/approachThe proposed model uses online survey data from 855 participants. The data are analyzed using structural equation modeling. The relationship between celebrity credibility, commitment, and loyalty to the service provider is explored, with trust in the service provider acting as a mediator. The profession and gender of celebrities are considered moderators.FindingsTrust in service providers partially mediates the relationship between celebrity credibility, customer loyalty, and commitment. Moderation results across multiple groups show that male and sports celebrities are more persuasive in expertise, and customers find women and movie stars to be more effective endorsers in the attractiveness dimension.Research limitations/implicationsThis study focuses only on banking services with data collected from a single country to examine a celebrity’s role as a spokesperson.Practical implicationsConsidering the benefits of having a well-known celebrity as a spokesperson for financial services like banking is intriguing. Given the unique characteristics and significant perceived risk associated with financial services, marketers may consider hiring celebrity endorsers to increase tangibility and reduce risk.Originality/valueThe results of this study may provide a deeper understanding of the combined effect of celebrity credibility and trust in financial service providers, which provides tangibility and helps establish a strong customer relationship.

CO2‐fertilisation enhances resilience to browsing in the recruitment phase of an encroaching savanna tree

Published: October 2022

Abstract

CO2‐fertilisation is implicated in the widespread and significant woody encroachment of savannas due to CO2‐stimulated increases in below‐ground reserves that enhance sapling regrowth after fire. However, the effect of CO2 concentration ([CO2]) on tree responses to the other major disturbance in savannas, herbivory, is poorly understood. Herbivory responses cannot be predicted from fire responses, as herbivore effects occur earlier during establishment and are moderated by plant palatability and defence rather than below‐ground carbon accumulation.

The relationship between herbivory and [CO2] is explored here using a widespread, strongly encroaching savanna tree, Vachellia karroo. Using greenhouse‐grown seedlings under past—through to predicted future—[CO2] (180–1000 ppm) and field‐grown seedlings under ambient [CO2], we assessed plant survival, growth, defence and palatability.

Increasing [CO2] improves the tolerance of greenhouse‐grown seedlings to herbivory by stimulating growth and allowing a critical size threshold associated with survival to be reached earlier, thereby decreasing the probability of fatal herbivory during the vulnerable recruitment phase. Elevated [CO2] also decreases the time taken to reach a second size threshold linked to accelerated recovery of field‐grown seedlings following herbivory. Seedling growth responses to increasing [CO2] are nonlinear, suggesting that historic growth and survival enhancements are smaller than those predicted for the future. Increasing [CO2] is associated with greater resistance to herbivores (more branched shoot architecture) but not leaf palatability (C:N ratio) or defence (leaf tannins and spine density).

Increasing V. karroo densities already constitute a major land management problem in southern African savannas. However, encroachment by this species, and likely other savanna tree species, may be greatly exacerbated under future [CO2], as tolerance to herbivory at the recruitment stage is further enhanced.

Abstract

Drought events induced by global climate change strongly modify ecosystem structure and function in grasslands. Higher plant biodiversity can enhance ecosystem resistance to drought; however, the potential effects of drought on the relationships between above‐ground productivity (ANPP) and biodiversity along a natural aridity gradient remain poorly understood.

Here, we studied the effects of experimental drought on plant community structure and ANPP during the two different dry years (2015 and 2017) spanning three temperate steppe sites with low‐, medium‐ and high‐aridity levels. We also examined the effects of drought and aridity on the associations of plant species (richness and abundance), functional (community‐weighted trait means and functional dispersion) and phylogenetic diversity (evolutionary lineages) with ANPP. A structural equation modelling (SEM) was used to elucidate how the drought affected ANPP by altering biodiversity attributes.

We found that experimental drought shaped the biodiversity–ANPP relationships, and the biodiversity–ANPP relationships differed among three sites. At the low‐aridity site, ANPP was correlated with plant functional traits, whereas ANPP was correlated with functional dispersion, species and phylogenetic diversity at the medium‐aridity site. At the high‐aridity site, ANPP was correlated with species richness, functional traits and phylogenetic diversity. Compared with 2015, natural drought in 2017 strengthened the associations of species diversity, functional dispersion, leaf dry matter content and leaf nitrogen content with ANPP across three sites. SEM further showed that both experimental and natural drought directly decreased ANPP and indirectly decreased ANPP by reducing community‐weighted mean of plant height.

Synthesis. These results suggest that the aridity increase or drought occurrence is likely to induce the shifts in the associations of ANPP with species and functional diversity, highlighting the important role of water availability or precipitation conditions in regulating the biodiversity–ANPP relationships in temperate steppes. Overall, functional traits related to plant size play a crucial role in modulating the response of productivity to drought across three steppe sites. Thus, to buffer the negative effects of drought on steppe ANPP should pay attention to protect the species with large plant size.

Authority: On the revaluation of a value
Authors: Tonner Philip 
Published: October 2022

AbstractThis paper, while not presenting a general discussion of authority in education, attempts to uncover some of the anomalies, paradoxes and tensions in the concept. It will argue for a revaluation of authority as an educational virtue, as a form of participatory guidance that is an aid to growth. The paper intends to help provoke continued debate over our perceived educational virtues and vices. I argue that virtuous authority is authority exercised from the point of view of a larger experience and a wider horizon. If teachers' ‘pedagogical imperative’ is to bridge the gap between forms of knowledge and their pupils, then their practice will involve authority. I suggest here that such authority should be repositioned as participatory, immanent and democratic. As Dewey says, ‘The need for authority is…constant…[I]t is the need for principles that are both stable enough and flexible enough to give direction to the processes of living in its vicissitudes and uncertainties.’ In answer to this, I suggest that teachers practice their authority in order to create stable yet flexible, open and indeterminate, but not chaotic situations that combine with pupils’ experiences in such a way as to enable educational growth. Authority practised as a form of participatory guidance, to pursue this Deweyan line of argument, can be ‘an aid to freedom’ and not freedom's enemy. This paper will argue that authority, so revalued, ought to be cultivated in our educational thought and practice. Eds: This paper forms part of a Special Issue titled ‘Beyond Virtue and Vice: Education for a Darker Age’, in which the editors invited authors to engage in exercises of ‘transvaluation’. Certain apparently settled educational concepts (from agency and fulfilment to alienation and ignorance) can be reinterpreted and transvaluated (in a Nietzschean vein) such that virtues become vices, and vices, virtues. The editors encouraged authors to employ polemics and some occasional exaggeration to reimagine educational values that are all too readily accepted within contemporary educational discourses.

Published: October 2022

ObjectivesVariceal hemorrhage is a fatal complication of cirrhosis. In this study, we aimed to investigate the role of serum interleukin 2 receptor (sIL‐2R) as a predictive indicator in patients with a previous history of cirrhosis‐related variceal bleeding.MethodsA total of 340 cirrhotic patients who had experienced variceal bleeding from December 2016 to December 2018 were enrolled, and were randomly assigned to the modeling group and the validation group. The 3‐year variceal rebleeding rate and other outcomes including adverse events were analyzed between patients with different sIL‐2R levels.ResultsA time‐dependent receiver operating characteristic (ROC) curve of variceal rebleeding indicated that sIL‐2R had an area under the ROC curve (AUROC] of 0.731 and 0.837 for the modeling and validation groups, respectively, with a cut‐off value of 426 U/mL. Kaplan–Meier analysis showed that higher sIL‐2R level was related to an increased risk of variceal rebleeding rate (55.33% vs 24.34%, P = 0.024 and 51.28% vs 15.32%, P = 0.049) and decreased 3‐year survival rate (91.16% vs 98.92%, P = 0.013 and 90.52% vs 97.50%, P = 0.180) in the modeling and validation groups. Elevated sIL‐2R levels were associated with an increased risk of portal vein thrombosis and severe ascites as well as inferior liver function, hypercoagulable state, and increased portal pressure.ConclusionHigh sIL‐2R levels were associated with poor prognosis in cirrhotic patients with previous variceal bleeding.

AbstractIntroduction123I‐MIBG scan is used in neuroblastoma (NB) to monitor treatment response. Time to resolution of 123I‐MIBG avidity after radiation therapy (RT) is unknown. We sought to determine time to resolution of 123I‐MIBG avidity after RT and local failure (LF) rate.MethodsWe performed a retrospective review of children with high‐risk NB who underwent 123I‐MIBG scans pre‐ and post‐RT from 2003 to 2019. Time from RT to resolution of 123I‐MIBG activity was analysed. LF and cumulative incidence of local progression (CILP) after RT stratified by site, presence of residual disease and use of boost RT were determined.ResultsForty‐two patients with median age 3.9 years (1.9–4.7 years) were included, with median follow‐up time 3.9 years (1.4–6.9). Eighty‐six lesions were treated with RT to median dose of 21.6 Gy. Eighteen of 86 lesions were evaluable for time to resolution of MIBG avidity after RT, with median resolution time of 78 days (36–208). No LF occurred among 26 patients who received RT to primary sites after GTR, versus 4/12 (25%) patients treated with residual primary disease. 2‐year CILP was 19% (12% primary disease 25% metastatic disease (P = 0.18)). 2‐year CILP for non‐residual primary, residual primary, non‐residual metastatic and residual metastatic lesions was 0%, 42%, 11% and 30% respectively (P = 0.01) and for boosted and non‐boosted residual lesions was 29% and 35% (P = 0.44).ConclusionMedian time to MIBG resolution after RT was 78 days. Primary lesions without residual disease had excellent local control. LF rate was higher after RT for residual disease, with no benefit for boost RT.
