Long-term structural plasticity of hippocampal dendritic spines following contextual fear memory reactivation

Published: May 2023

AbstractDendritic spines are plastic structures exhibiting a high degree of morphological variability. Certain morphometric parameters, such as volume, positively correlate with the strength of the synapse in which they participate. Memories, too, are subject to change over time and with experiences. In particular, the presence of a reminder of a learning event can trigger the labilization of the memory trace, followed by a re-stabilization process termed reconsolidation. The underlying mechanisms behind the labilization/reconsolidation processes are of great interest, as they are thought of as possible targets for the treatment of post-traumatic stress disorders. Dendritic spines have long been considered the physical sites for memory formation and storage. Our work aimed at studying the long-term spine morphological plasticity associated with labilization/reconsolidation in the dorsal hippocampus, a brain region relevant for the formation of contextual memories. Our results suggest that labilization/reconsolidation does not affect spine density, but rather induces changes in spine morphology. Furthermore, we show that some of these changes are prevented by the inhibition of the transcription factor NF-κB inhibition. Finally, we found that NF-κB negative modulation also affects spine morphology in animals that were not exposed to recall but have undergone the training session, suggesting that there may be a late surge of NF-κB activity resulting from the consolidation itself.

Published: May 2023

PurposeThis study investigated employee cynicism and workplace ostracism as pathways through which perceived organizational politics (POPs) is related to counterproductive work behavior (CWB) targeted at individual coworkers (CWB-I) and the organization (CWB-O).Design/methodology/approachData were collected from 794 university employees in Southeastern, Nigeria at three-point of measurements.FindingsResults of the Structural Equation Modelling showed that POPs positively predicted CWB-I but did not predict CWB-O directly. POPs positively predicted both employee cynicism and workplace ostracism. Employee cynicism did not predict CWB-I and CWB-O, but workplace ostracism positively predicted both CWB-I and CWB-O. Moreover, whilst POPs did not predict both CWB-I and CWB-O through employee cynicism; workplace ostracism partially mediated the relationship between POPs and the two dimensions of CWB.Originality/valueThe relationship between POPs and CWB has been documented in the literature, but whether affect-laden processes (employee cynicism and workplace ostracism) explain this relationship is new. Conducting the study in a context previously neglected extended our understanding of the indirect relationship between POPs and CWB.
A study of cash waqf contribution between millennials of Malaysia and Indonesia
Authors: Allah Pitchay Anwar , Sukmana Raditya , Ratnasari Ririn Tri , Abd Jalil Mohamad Isa 
Published: May 2023

Purpose
This study aims to examine the determinants of motivation that influences Malaysian and Indonesian millennials to contribute cash waqf.

Design/methodology/approach
The present study used self-determination theory and 423 respondents, of which 205 respondents are from Malaysia and 218 from Indonesia. The study developed a self-administrative questionnaire, and it is distributed through an online survey method, and the data are analysed using SmartPLS partial least squares analysis.

Findings
The results show that perceived donor effectiveness and moral obligation factors influence both Malaysians and Indonesian millennials to make cash waqf contributions. Meanwhile, the face concern factor did not significantly affect millennials in Malaysia and Indonesia to contribute cash waqf. Furthermore, the sense of self-worth factor appears to significantly influence only Indonesian millennials but not Malaysian millennials.

Research limitations/implications
The research findings have significant theoretical and practical ramifications. Firstly, while face concern has a positive effect on millennials’ willingness to contribute cash to waqf, it is not statistically significant in Muslim populations. This implies that to persuade millennials to make cash waqf contributions, the face concern argument should be avoided.

Originality/value
The comparative study between Malaysia and Indonesia adds new value to this study. These two Muslim majority countries have similar attributes in terms of religion, demography and race background. Furthermore, the focus of this study, which targets units of analysis from millennials, has received very little attention in the literature related to cash waqf.
Factors influencing SMEs’ intention to adopt electronic tendering: empirical evidence from an emerging African market

Published: May 2023

PurposeDespite the digitalization reforms attempting to enhance public service quality, paper-based tendering is still widely used in a number of developing countries (i.e. Morocco). This has led to many issues including waste of time, higher costs as well as labor-intensive issues. E-tendering has been widely recommended as a key resolution. Still, both scholars and practitioners raised concerns related the readiness of small and medium enterprises (SMEs) to this digitalization process. The current research aims to investigate the key drivers of SMEs intention to adopt electronic tendering in the context of an emerging African market (i.e. Morocco). Specifically, the authors focus on SMEs contributing to the public procurement process and registered in the online portal recently created by the Moroccan government.Design/methodology/approachTo achieve this goal, the authors proposed a conceptual model combining the unified theory of acceptance and use of technology (UTAUT) and technology acceptance model (TAM). Based on data collected from suppliers participating in Moroccan public tenders, the authors empirically tested the conceptual model using a partial least squares (PLS) estimation.FindingsFacilitating conditions and social influence had a positive impact on SMEs intention to adopt electronic tendering. The study’s findings also convey a negative impact of effort expectancy on SMEs intent to adopt e-tendering. Unexpectedly, perceived performance had no significant impact on the intention to adopt electronic bidding among Moroccan SMEs.Originality/valueThis research filled the gap in the literature with regards to SMEs e-Tendering readiness in emerging markets. With the recent digitalization reforms of public tendering in many developing economies (i.e. Morocco), the study findings can be used to improve not only government implementation of electronic bidding but also SMEs' user experience.

Published: May 2023

Purpose
Peer Support Specialists (PSS) play an integral role in substance use disorder treatment and aftercare services. PSS training programs vary in format and need to be evaluated for continued improvement. The purpose of this study was to gather feedback about course delivery and instruction from PSS trainees in a PSS training program in Alabama.

Design/methodology/approach
Focus groups were conducted with 15 PSS trainees after they completed two training courses delivered in an online university format. There were four men and 11 women. Four were black, 10 were white and one was Hispanic/Latinx. Participants ranged in age from 20 to 70.

Findings
Through content analysis of focus group content, four themes emerged: (1) issues with online navigation, (2) desire for an orientation to university-level education, (3) instructor qualities (e.g. approachability and availability) and (4) course structure considerations (e.g. balance between online and in-person learning, more frequent class meetings).

Originality/value
To the best of the authors’ knowledge, this study is the first to evaluate a new PSS training program in Alabama. Findings help inform future PSS training programs and assist in the development of best practices in PSS training.
Impact of Bitcoin mining and crypto market determinants on Bitcoin-based energy consumption
Authors: Sapra Nishant , Shaikh Imlak 
Published: May 2023

PurposeWhile Blockchain can serve us, Bitcoin threatens our survival. If Bitcoin is assumed to be a country, it will rank 38th globally for energy consumption. With 90.2 metric million tonnes of carbon dioxide, Bitcoin mining and trading has emerged as an environmental threat. The current study investigates how the trading-specific variables, the prices of Crypto Index and Ethereum, affect bitcoin-based energy consumption. Also, the role of mining-specific variables is analyzed.Design/methodology/approachThe study uses monthly data from various sources collected from December 2018 to January 2023. The authors used the Autoregressive Distributed Lag (ARDL) Model to determine the short- and long-term relationships between variables. This study uses the Theory of Green Marketing and the Theory of Cross Elasticity of Demand as a theoretical lens.FindingsThe findings show that escalating crypto market index and Ethereum prices with a one-month lag increases bitcoin-specific electricity consumption and carbon emissions. Green investors may shift to cryptocurrencies based on consensus other than of Proof-of-Work. Ethereum behaves like a substitute for Bitcoin, reflected by the long-term positive relationship between Bitcoin's energy consumption and Ethereum prices.Originality/valueThe study analyses how the crypto market index and Ethereum price affect bitcoin-based energy use. The relationships identified are substantiated by the literature to provide suggestions to green investors and policymakers to mitigate the harmful impact of Bitcoin's colossal energy consumption on the natural environment.
Incentive mechanism for promoting the uptake of green building in South Africa
Authors: Simpeh Eric Kwame , Smallwood John Julian 
Published: May 2023

PurposeThe green building (GB) market is maturing after years of practice; therefore, incentives for promoting GB should be adapted to reflect the market transformation. Adapting incentives can positively influence stakeholders' motives, which in turn change stakeholders' behavioural intention towards GBs. Hence, this study aims to examine the parameters influencing the decision to adopt GB and to ascertain how incentive mechanisms promote the uptake of GB in South Africa.Design/methodology/approachUsing a scoping literature review and a sequential mixed research method, primary data were acquired from GB experts in four South African provinces. In analysing the quantitative data, the factors were ranked hierarchically using the mean ranking technique and factor analysis was computed to identify the underlying GB incentives. The qualitative data were analysed using content analysis.FindingsThe results indicate that incentive payment from a utility energy efficiency programme, rebates and discounts relating to environmentally friendly materials and products and providing grants to homeowners and developers to go towards certification were the most essential monetary incentives for promoting GB. In the category of non-monetary incentives, recognition of consultant team members and developers and free marketing/good publicity were the most important incentives. The incentive mechanisms were subsequently categorised as “Economic incentives” and “Reward scheme and technical support”.Research limitations/implicationsThis study was confined to four metropolitan areas in South Africa. Nevertheless, the outcomes have practical implications for GB projects in general and may serve as a good reference for other provinces in South Africa.Originality/valueThe findings of the study are a valuable resource for stakeholders such as the government, municipal assemblies, professional bodies and the Green Building Council of South Africa (GBCSA) in developing effective incentive mechanisms to promote GB adoption. This study adds to the body of knowledge relevant to GB incentivisation in South Africa.
Eco-friendly materials knitting by different yarn ply for high-performance garments
Authors: Abo El Naga Heba Tolla El Sayed , Abd El-Aziz Manar Yahia Ismail 
Published: May 2023

Purpose
Synthetic materials have many drawbacks in high-performance garments because they absorb less moisture and cause allergies to sensitive individuals. Cotton materials cannot satisfy all the requirements and cannot provide the required high performance. This study aims to use eco-friendly materials with a common structure to analyse their suitability for high-performance garment application.

Design/methodology/approach
This study used two eco-friendly yarns (bamboo, modal and bamboo: modal 50:50) and yarns per needle (two- and four-ply yarns). with a single jersey knit construction and gauge of 7. The physical, mechanical, appearance, comfort, thermal and ultraviolet protection factor (UPF) protection characteristics were evaluated using 15 tests.

Findings
The produced knitted fabrics showed high performance for use as garments with physical, mechanical, appearance, comfort, thermal and UPF protection characteristics that were achieved, tested and analysed. The highest-achieved samples with a good UPF (>15) were made from bamboo material, which has other high-performance characteristics such as antibacterial characteristics, a soft surface, thermal insulation and others.

Research limitations/implications
The single jersey structure was used for producing fabrics as it is the common structure in the garment. Also, only gauge 7 was used for its economics and ease of production.
BATScan: A radar classification tool reveals large‐scale bat migration patterns
Authors: Werber Yuval , Sextin Hadar , Yovel Yossi , Sapir Nir 
Published: May 2023

Abstract

Bat movement and behaviour are still mostly understudied over large scales. High‐altitude, nocturnal activity makes visual identification of bats from the ground virtually impossible, dramatically hindering our ability to study their movement ecology. Despite the wide use of radar in aeroecology, its application to study specific taxa is limited due to incomplete target classification abilities. BATScan is a bat classifier for vertical‐looking radar data, which enables identifying bats and characterizing their unique aeroecology.

We constructed the classifier using data from 10 radar deployments, covering a wide range of habitats on a central bird migration flyway over a 7‐year period, comprising ~18 million observations. We analysed animal migration above the Hula Valley, home to over 30 species of bats spanning a range of 5–150 g in size and exhibiting a variety of ecological characteristics. We distinguished bat‐labelled radar echoes for training according to phenology, morphology and movement ecology of bats, birds and insects. Several non‐bat datasets were constructed and joined to train classifiers under increasing levels of difficulty. Class imbalance in the resulting training data was handled using a generative adversarial network for up‐sampling the much smaller bat dataset.
The resulting classification tool reached a high level of accuracy and precision, and was further scrutinized with an extensive set of ecological validations.

Bats perform seasonal migrations over long distances, but little is known about the spatial and temporal characteristics of this movement, and the ability to study it at a large scale has so far been limited. We present the Israeli BATScan dataset, containing over 60,000 bat observations spanning the entire country and representing multiple habitats. Using this data, we produce an unprecedented large scale, highly detailed documentation of the yearly movements of bats on a major migration flyway, and distinguish this pattern from bird migration over space and time.

So far, radar aeroecology dealt primarily with birds, increasingly with insects, and only rarely with bats. We present BATScan, a classification tool that can incorporate bats into the framework of radar aeroecology to finally enable a comprehensive description of animal aeroecology.
Work integration ambitions of startups in the circular economy
Authors: Van Opstal Wim , Borms Lize 
Published: May 2023

AbstractAn increasing number of studies illustrate and estimate the potential of the circular economy to create new jobs, most particularly for vulnerable groups at the labor market. This creates collaborating opportunities for Work Integration Social Enterprises (WISEs) and circular economy ventures. Since a shift to a circular economy requires new visions and strategies, startups are considered as powerful engines for the innovation processes needed to support a circular transition. Nevertheless, academic literature at the crossroads of the circular economy, work integration of target groups, and startups remains quasi non‐existent. In this paper we present results from survey‐data of startups with varying implementation levels of circular strategies, and assess their willingness to cooperate with WISEs, or to engage in other forms of target group employment. We find a strong positive relationship between the implementation of circular strategies and work integration ambitions among startups. Circular startups who need skills on production, transportation, and logistics seek collaboration with WISEs for both inner (repair and redesign) and outer circle (recycling) strategies. Our findings suggest that the circular social economy faces specific barriers that need tailor‐made enabling policies. We recommend WISEs to explicitly assess reskilling and upskilling opportunities while embracing the circular economy as a future‐proof economic activity.

AimsTo provideposthocanalyses of a clinical trial that reported beneficial effects of medication reviews on health‐related quality of life. Specifically, to describe the medication changes with a focus on deprescribing and to explore patient‐ and medication‐related factors that may identify patients most likely to benefit from medication reviews.MethodsPosthocanalyses of data from a pragmatic, nonblinded, randomized clinical trial investigating a medication review intervention (NCT03911934) in 408 geriatric outpatients treated with ≥9 medicines.ResultsIn the medication review group (n = 196), 26% of the medicines prescribed at baseline were discontinued with 82% still being discontinued after 13 months. The most common reason for discontinuation was lack of indication (72% of discontinuations). The medicines most often discontinued in the medication review group compared with usual care included: metoclopramide (11/15 = 73% discontinuedvs. 1/12 = 8% in usual care), acetylsalicylic acid (20/48 = 42%vs. 2/47 = 4%), simvastatin (18/48 = 38%vs. 2/58 = 3%), zopiclone (23/59 = 39%vs. 4/54 = 7%), quinine (9/14 = 64%vs. 6/16 = 38%), citalopram (4/18 = 22%vs. 0/20 = 0%) and tramadol (18/37 = 49%vs. 8/30 = 27%). Factors associated with number of deprescribed medicines included: number of prescribed medicines, Drug Burden Index, patient motivation for medicine changes, and prescriptions of metoclopramide, iron preparations, antidepressants other than selective serotonin reuptake inhibitors, nonsteroidal anti‐inflammatory drugs, or drugs for urinary incontinence.ConclusionPhysician‐led medication reviews resulted in persistent deprescribing of medicines in older polypharmacy patients treated with ≥9 medicines. Motivation for having their medicine changed, treatment with more medicines, and a higher burden of sedative and anticholinergic medicines characterized the patients most likely to benefit from physician‐led medication reviews.
Native vegetation structure, landscape features and climate shape non‐native plant richness and cover in New Zealand native shrublands
Authors: Rossignaud Laureline , Hulme Philip E. 
Published: May 2023

AbstractAimStudies investigating the determinants of plant invasions rarely examine multiple factors and often only focus on the role played by native plant species richness. By contrast, we explored how vegetation structure, landscape features and climate shape non‐native plant invasions across New Zealand in mānuka and kānuka shrublands.LocationNew Zealand.MethodWe based our analysis on 247 permanent 20 × 20‐m plots distributed across New Zealand surveyed between 2009 and 2014. We calculated native plant species richness and cumulative cover at ground, understorey and canopy tiers. We examined non‐native species richness and mean species ground cover in relation to vegetation structure (native richness and cumulative cover), landscape features (proportion of adjacent anthropogenic land cover, distance to nearest road or river) and climate. We used generalized additive models (GAM) to assess which variables had greatest importance in determining non‐native richness and mean ground cover and whether these variables had a similar effect on native species in the ground tier.ResultsA positive relationship between native and non‐native plant species richness was not due to their similar responses to the variables examined in this study. Higher native canopy richness resulted in lower non‐native richness and mean ground cover, whereas higher native ground richness was associated with higher native canopy richness. Non‐native richness and mean ground cover increased with the proportion of adjacent anthropogenic land cover, whereas for native richness and mean ground cover, this relationship was negative. Non‐native richness increased in drier areas, while native richness was more influenced by temperature.Main ConclusionsAdjacent anthropogenic land cover seems to not only facilitate non‐native species arrival by being a source of propagules but also aids their establishment as a result of fragmentation. Our results highlight the importance of examining both cover and richness in different vegetation tiers to better understand non‐native plant invasions.
