On the angular anisotropy of the randomly averaged magnetic neutron scattering cross section of nanoparticles
Authors: Adams Michael P. , Pratami Sinaga Evelyn , Michels Andreas
Published: March 2023

The magnetic small-angle neutron scattering (SANS) cross section of dilute ensembles of uniformly magnetized and randomly oriented Stoner–Wohlfarth particles is calculated using the Landau–Lifshitz equation. The focus of this study is on the angular anisotropy of the magnetic SANS signal as it can be seen on a two-dimensional position-sensitive detector. Depending on the symmetry of the magnetic anisotropy of the particles (e.g. uniaxial, cubic), an anisotropic magnetic SANS pattern may result, even in the remanent state or at the coercive field. The case of inhomogeneously magnetized particles and the effects of a particle-size distribution and interparticle correlations are also discussed.

Authors: Srirangam Sucharita , Gunasagaran Sujatavani , Mari TamilSalvi , Ng Veronica , Kusumo Camelia May Li
Published: March 2023

Purpose

There is an urgent need to develop a systematic tool for urban design in the cities of the Klang Valley, Malaysia. Sustainable Development Goal 11 (SDG11) proposes ideas to make cities and human settlements inclusive, safe, resilient and sustainable. This paper approaches this goal through land use, integrated into an effective connectivity network. It offers a scientific and systematic approach. The research employs Space Syntax of the University College London as a tool for urban analysis and the principles of Sustainable Street Networks developed by the Congress of New Urbanism to respond to connectivity issues.

Design/methodology/approach

The paper employs empirical research through case studies. A systematic literature review is conducted on the diversified applications of the Space Syntax correlations, which steered the fundamental analysis of the elements of deconstruction to structure and land use. Space Syntax and Sustainable Street Network characteristics were the essential research methods. It is important to note that these data a new finding on the Syntactic Maps of the two case study cities.

Findings

The paper summarises a set of results on (1) international comparison of spatial intelligence, (2) patterns from the Eastern cases and (3) theoretical guidelines for spatial intelligence through the Syntax by offering key characteristics of the New Urbanism principles, which could be considered, while revitalising the cities in the Klang Valley, Malaysia.

Research limitations/implications

The findings are specific and applicable to the oriental contexts. However, such results have been further compared to the Western context.

Practical implications

The study develops a toolkit for urban planners and designers and architects in Klang Valley, Malaysia.

Social implications

The research has focused and will add value for SDG11: Sustainable Cities and Communities. Theoretically, the paper offers insights to urban design readers.

Originality/value

It is important to note that the data itself is a new finding on Syntactic Maps of the two case study cities. The investigated setting is unique, and the first attempt in generating a Space Syntax map to the cities of Klang Valley, and the findings, therefore, offer a new set of knowledge-base to the city planners, urban designers, researchers and architects.
Implementing psychologically informed environments in homelessness services: a qualitative exploration of staff teams’ self-assessments
Authors: Buckley Sophie , Tickle Anna
Published: March 2023

Purpose

This study aims to explore the perceptions of staff in four teams regarding the implementation of psychologically informed environments (PIE) across a community service and three hostels supporting individuals facing severe and multiple disadvantage.

Design/methodology/approach

Using a pre-post design, the PIEs Assessment and Self-Development for Services (known as the Pizazz) was completed by staff before the implementation of PIEs and at a six-month follow-up. A narrative review of the results and thematic analysis of the qualitative data are presented.

Findings

The majority of the Pizazz elements were rated as improved following PIE implementation. Thematic analysis developed three themes influencing staff members’ ability to develop a PIE: Complexities of Our and Wider Systems; Ready-made or Baked from Scratch; and Reflective and Responsive Staff.

Research limitations/implications

A planned one-year follow-up was obstructed by the coronavirus pandemic, limiting understanding of longer-term impact. Having only gathered data from staff members, the results cannot corroborate staff members’ perceptions. Further research could explore other stakeholder perspectives, as well as the impact of PIE implementation on staff perception of resources, and of a possible ceiling effect for hostels trying to develop PIE.

Originality/value

To the authors’ best of knowledge, this is the first UK study to use the Pizazz to evaluate the implementation of PIE.
Business model patterns in the 3D food printing industry
Authors: Nopparat Nanond , Motte Damien
Published: March 2023

Purpose

Present for more than 20 years, 3D food printing (3DFP) technology has not experienced the same widespread adoption as its non-food counterparts. It is believed that relevant business models are crucial for its expansion. The purpose of this study is to identify the dominant prototypical business models and patterns in the 3DFP industry. The knowledge gained could be used to provide directions for business model innovation in this industry.

Design/methodology/approach

The authors established a business model framework and used it to analyse the identified 3DFP manufacturers. The authors qualitatively identified the market’s prototypical business models and used agglomerative hierarchical clustering to extract further patterns.

Findings

All identified 3DFP businesses use the prototypical business model of selling ownership of physical assets, with some variations. Low-cost 3D food printers for private usage and dedicated 3D food printers for small-scale food producers are the two primary patterns identified. Furthermore, several benefits of 3DFP technology are not being used, and the identified manufacturers are barely present in high-revenue markets, which prevents them from driving technological innovation forward.

Practical implications

The extracted patterns can be used by the companies within the 3DFP industry and even in other additive manufacturing segments to reflect upon, refine or renew their business model. Some directions for business model innovation in this industry are provided.

Originality/value

To the best of the authors’ knowledge, this is the first quantitative study to give an account of the current 3DFP business models and their possible evolution. This study also contributes to the business model patterns methodological development.
When should central banks engage in private sector securities purchases?
Authors: Michael Bryane , Dalko Viktoria
Published: March 2023

Purpose

The authors aim to look at the conditions under which central bank easing – and specifically the purchase of private sector securities – can/should contribute to growth, rather than fiscal policy and also ask when can the central bank’s purchase of private sector securities help supplant traditional monetary policy.

Design/methodology/approach

After surveying the existing literature, the authors use simple correlation of central bank private asset (stocks, bonds, etc.), interest rates, gross domestic product (GDP) growth, inflation and the extent of the functioning of domestic banking sectors (among others) to classify countries in which these purchases promote pro-growth investment.

Findings

Under the typical conditions for unconventional monetary policy, central bank purchases of private companies’ securities can promote growth in some places (like Bulgaria, the Ukraine, Georgia and Greece at the time of our writing) while hurting it in others (like in parts of Latin America and Africa in the mid-2010s). The authors find how such purchases effectively “bypass” dysfunctional banking systems and central/government local bodies fiscal spending, making the central bank the “funder of last resort” in many middle and lower income countries.

Practical implications

This paper tells specific central banks to ramp up – or reduce – their purchases of private sector securities. The authors identify exact jurisdictions where such “helicopter money” has led to investment in the past economic growth.

Originality/value

All previous work on conventional and unconventional monetary policy has looked at the way monetary policy affects investment and growth through the banking system and holding companies’ reactions constant. The authors do the opposite – looking at how companies respond, holding banking system responses constant. No one has ever looked at these private purchases (taken from a special IMF database), much less tried to argue that central banks can sometimes target investment growth much better than fiscal policy. No one has ever considered them as a funder (rather than lender) of last resort.
Is knowledge hiding in higher education a political phenomenon? An explanatory sequential approach to explore non-linear and three-way interaction effects
Authors: Modem Roopa , Lakshminarayanan Sethumadhavan , Pattusamy Murugan , Pillai K. Rajasekharan , Prabhu Nandan
Published: March 2023

Purpose

This study addresses a central research question: Is individuals’ propensity to hide knowledge a “political phenomenon” among researchers in the Indian higher education institutions? Drawing upon social exchange and uncertainty management theories, the authors examine how a three-way interaction effect of perceptions of organizational politics, political will and political skill contributes to knowledge hiding. In addition, this study aims to develop a nuanced understanding of the knowledge hiding phenomenon in the Indian higher education context.

Design/methodology/approach

This study adopts a mixed-method study design with an explanatory sequential approach. The authors gathered data through a cross-sectional survey of 286 researchers (Study 1) followed by two focus group discussions (Study 2) involving 13 academic researchers from five Indian universities. The sample includes full-time faculty members, postgraduate and full-time doctoral students engaged in research.

Findings

The results of Study 1 indicate that researchers’ perceptions of organizational politics positively relate to their knowledge hiding. The findings of this study also suggest that the positive relationship between perceptions of organizational politics and knowledge hiding turns negative for individuals with high political will and high political skill. The focus group discussions (Study 2) explore significant predictors of knowledge hiding. This study unveils various characteristics of knowledge, knowledge hider, knowledge seeker and interpersonal dynamics as the key drivers of knowledge hiding in Indian academia.

Originality/value

The significant contributions of this study are to provide new insights into the relationship between organizational politics and knowledge hiding and to unravel the various factors that incite knowledge hiding among researchers in the Indian higher education context. This study is one among the few in the knowledge hiding literature to adopt a mixed-method research design with an explanatory sequential approach.
War build-up and stock returns: evidence from Russian and Ukrainian stock markets
Authors: Najaf Khakan , Joshipura Mayank , Alshater Muneer M.
Published: March 2023

Purpose

This study examined the impact of war/conflict-related news on the Russian and Ukrainian stock markets in the build-up and beginning of the war that sparked in the year 2022.

Design/methodology/approach

In order to examine the impact of war-related news on stock returns, data were gathered from the United States (US) and Russian stock indices, oil price and volatile index (VIX) from Yahoo.finance; Ukrainian stock values from pfts.ua website and daily related news retrieved from nexis.com were analysed. The data were gathered from January 1, 2022 to February 24, 2022. Seeming unrealated regressions (SUR) and exponential generalised autoregressive conditional heteroscedastic (EGARCH) models were carried out to determine the formulated correlations. This study controlled the oil price, US stock returns, Chicago Board Options Exchange (CBOE) VIX and difference in stock returns of Russia and Ukraine.

Findings

The results are presented two-fold: first, war-related news between the two countries enhanced volatility and caused a significant decline in the stock market indices for both countries. Second, the Russian stock market faced a steeper decline in the build-up and the actual beginning of the war than the Ukrainian stock market. Notably, the Russian markets feared the adverse economic consequences that stemmed from the sanctions the US and the Western world imposed.

Research limitations/implications

As this study was based on early evidence, future studies with a longer window may provide better insights. This present study is restricted to the stock returns of the countries directly involved in the build-up towards war. Studies focusing on the impact of other asset classes, currencies, commodities and global stock markets might offer holistic insights.

Practical implications

The study outcomes suggest that global portfolio investors should stay away from stock markets of the war-raged countries and equity markets in general, but instead look for safe-haven assets.

Originality/value

The paper evaluates stock markets' performance during the pre-war period, considering the context of this historical war between the neighbours. It is important to understand this issue as this war is subject to sanctions by the US and leads to a global supply chain crisis.
Natural dyeing of silk and jute fabric with the aqueous extract of coconut leaves – an eco-friendly approach
Authors: Hossain Shahin , Jalil M. Abdul , Mahmud Rois Uddin , Kader Abdul
Published: March 2023

Purpose

In recent years, natural dyes have attracted significant attention globally because of growing public awareness of the environment and health hazards associated with synthetic dyes. Natural dyes can provide special aesthetic qualities as well as the ethical significance of a product which is environmentally friendly. By keeping this burning issue in mind, this study aims to explore the dyeing properties of various unexplored environmentally friendly natural dyes.

Design/methodology/approach

In this study, the aqueous extract of coconut leaves is used for dyeing purpose. The silk and jute fabrics were dyed with the extract alone as well as in combination with metal salts as mordants by employing pre-, meta- and postmordanting techniques. The dyeing properties of the colored samples were evaluated by measuring their color strength; CIEL*a*b* values; and color fastness to washing, light and rubbing.

Findings

A yellow shade was achieved when the fabric samples were dyed solely with the extract. However, shade variations were observed when different mordants and mordanting techniques were applied. In all the cases, metallic salts improved the color fastness properties of dyed samples to washing, light and rubbing especially for the silk fabric.

Originality/value

To the best of the authors’ knowledge, this is the first report on a natural dye extracted from the leaves of coconut. Leaf as the source of dye has added an extra advantage, as it is reproducible and can be collected easily without harming the plants. The reported dye could be an attractive choice for sustainable and eco-friendly dyeing.
Combined analysis of resistivity and induced polarization tomography for 3D modelling and preliminary volume estimation of the possible gold mineralization zones in the Simi locality, Adamawa, Cameroon
Authors: Ndam Njikam Mohamed Moustapha , Yem Mbida , Meying Arsène , Ribodetti Alessandra , Messi Gabriel , Tethys‐Authie Chiewo Ceukou , Zoumanigui Jean Maoro
Published: March 2023

The present study attempts to combine direct current and induced polarization methods for 3D geological modelling and preliminary volume estimation of gold mineralization targets in the Simi locality, Adamawa, Cameroon. To begin, resistivity and chargeability data were collected along seven profiles oriented in N150E using the electrical tomography technique. A geological investigation was also carried out and allowed in addition to the geological formations to highlight the existence of gold mineralization in the study area. The interpretation of the inversion results was done by taking into consideration the geological field data and the existing resistivity charts. The 3D distribution of the interpreted sections allowed us to make a horizontal correlation between the different sections and to elaborate the 3D geological model of the study area by using the deterministic inverse distance method. The estimated model indicates a volume of 621,130.625 m3 of the possible gold complex. The gold complex was then divided into two mineralization domains based on chargeability ranges (mV/V): A first domain is associated with a major mineralization zone (39–60 mV/V) with a volume of 10,842 m3, and a second domain is associated with secondary mineralization zone (18–39 mV/V) with a volume of 610,288 m3. This model allows to compartmentalize the gold complex and can be used as a base model for the gold investigation in the study area.
Calibration of near‐surface multi‐frequency electromagnetic induction data
Authors: Finco Cécile , Rejiba Fayçal , Schamper Cyril , Cavalcante Fraga Luis Henrique , Wang Ao
Published: March 2023

The frequency‐domain electromagnetic induction method is a very efficient and convenient method to investigate a site of interest and for a large range of applications including hydrogeology and archaeology. Besides an easy infield acquisition, the data can be used to estimate the electrical, magnetic and, in certain cases, dielectric properties of the ground. It does, however, require calibration to get reliable quantitative values of these properties. We propose here an original and reliable self‐calibration method, specific to multi‐frequency measurements in the range of (5–100 kHz)‐based only on the consistency between the data at different acquisition frequencies. Contrary to other existing cross‐calibration procedures, no additional measurements with other methods are necessary. This self‐calibration (quadrature and in‐phase components of the electromagnetic induction signal) procedure is tested at a test site located at the centre for studies on risks, the environment, mobility and urban planning Normandie‐Centre facilities (Rouen, France). The developed quadrature self‐calibration has been successfully compared with the usual electrical resistivity tomography – electromagnetic induction cross‐calibration procedure. The main results reveal the potential of systematic assessment of all electromagnetic parameters from multi‐frequency and multi‐configuration electromagnetic induction data: The electrical resistivity and the magnetic susceptibility are estimated from the low‐frequency range, whereas the highest part of the frequency range is used for the dielectric permittivity.
Lifecycle Earnings Risk and Insurance: New Evidence from Australia*
Authors: Tin Darapheak , Tran Chung
Published: March 2023

This paper studies the nature of earnings dynamics in Australia, using the Household, Income and Labour Dynamics in Australia (HILDA) Survey 2001–2020. Our results indicate that the distribution of earnings shocks displays negative skewness and excess kurtosis, deviating from the conventional linearity and normality assumptions. Wage changes are strongly associated with earnings changes and account more for the dispersion of earnings shocks; meanwhile, the contribution of hour changes is largely absent in upward movement and relatively small in downward movement of earnings changes. Furthermore, family and government insurance plays distinct roles in reducing exposure to earnings risk. Government insurance embedded in the targeted transfer system is important in mitigating the dispersion of shocks, whereas family insurance via income pooling and adjustment of secondary earners' labour market activities is dominant in reducing the magnitude and likelihood of extreme and rare shocks. The magnitude and persistence of earnings risk as well as the insurance role of family and government vary significantly across gender, marital and parental status. Accounting for these non‐Gaussian and non‐linearity features is important for evaluating the insurance role of government transfer programmes.
The future of crime data
Authors: Lauritsen Janet L.
Published: March 2023

Criminology lacks sufficient data for many types of crime that are of great concern to society. This lack of data poses significant problems for determining whether resources are adequate for responding to these crimes or whether programmatic, legislative, or target‐hardening efforts to prevent or reduce their occurrence are effective. Inadequate data about crime also produces a selective and incomplete narrative about crime that makes it easier for political and vested interests to exploit public concerns about crime for their own ends. In this address, I discuss what is needed to resolve these gaps and the ways in which criminologists can support a significant expansion of the crime data infrastructure. Such work is necessary to help ensure the future relevance of criminological research.
Autophagy in the retinal neurovascular unit: New perspectives into diabetic retinopathy
Authors: Yang Xiongyi , Huang Zexin , Xu Mei , Chen Yanxia , Cao Mingzhe , Yi Guoguo , Fu Min
Published: March 2023

Diabetic retinopathy (DR) is one of the most prevalent retinal disorders worldwide, and it is a major cause of vision impairment in individuals of productive age. Research has demonstrated the significance of autophagy in DR, which is a critical intracellular homeostasis mechanism required for the destruction and recovery of cytoplasmic components. Autophagy maintains the physiological function of senescent and impaired organelles under stress situations, thereby regulating cell fate via various signals. As the retina's functional and fundamental unit, the retinal neurovascular unit (NVU) is critical in keeping the retinal environment's stability and supporting the needs of retinal metabolism. However, autophagy is essential for the normal NVU structure and function. We discuss the strong association between DR and autophagy in this review, as well as the many kinds of autophagy and its crucial physiological activities in the retina. By evaluating the pathological changes of retinal NVU in DR and the latest advancements in the molecular mechanisms of autophagy that may be involved in the pathophysiology of DR in NVU, we seek to propose new ideas and methods for the prevention and treatment of DR.

Published: March 2023

Background

Patients with epidermal growth factor receptor (EGFR)‐mutated, advanced non–small cell lung cancer have received immunochemotherapy as one of the treatment options after tyrosine kinase inhibitor (TKI) failure.

Methods

We retrospectively examined EGFR‐mutant patients treated with atezolizumab‐bevacizumab‐carboplatin‐paclitaxel (ABCP) therapy or platinum‐based chemotherapy (Chemo) after EGFR‐TKI therapy at five institutions in Japan.

Results

A total of 57 patients with EGFR mutation were analyzed. The median progression‐free survival (PFS) and overall survival (OS) in the ABCP (n = 20) and Chemo (n = 37) were 5.6 and 20.9 months, 5.4 and 22.1 months, respectively (PFS, p = 0.39; OS, p = 0.61). In programmed death‐ligand 1 (PD‐L1)–positive patients, median PFS in the ABCP group was longer than in the Chemo group (6.9 vs. 4.7 months, p = 0.89). In PD‐L1–negative patients, median PFS in the ABCP group was significantly shorter than in the Chemo group (4.6 vs. 8.7 months, p = 0.04). There was no difference in median PFS between the ABCP and Chemo groups in the subgroups of brain metastases, EGFR mutation status, or chemotherapy regimens, respectively.

Conclusion

The effect of ABCP therapy and chemotherapy was comparable in EGFR‐mutant patients in a real‐world setting. The indication for immunochemotherapy should be carefully considered, especially in PD‐L1–negative patients.
Estimating the net effect of functional traits on fitness across species and environments
Authors: Siefert Andrew , Laughlin Daniel C.
Published: March 2023

Functional traits affect the demographic performance of individuals in their environment, leading to fitness differences that scale up to drive population dynamics and community assembly. Understanding the links between traits and fitness is, therefore, critical for predicting how populations and communities respond to environmental change. However, the net effects of traits on species fitness are largely unknown because we have lacked a framework for estimating fitness across multiple species and environments.

We present a modelling framework that integrates trait effects on demographic performance over the life cycles of individuals to estimate the net effect of traits on species fitness. This approach involves (1) modelling trait effects on individual demographic rates (growth, survival and recruitment) as multidimensional performance surfaces that vary with individual size and environment and (2) integrating these effects into a population model to project population growth rates (i.e., fitness) as a function of traits and environment. We illustrate our approach by estimating performance surfaces and fitness landscapes for trees across a temperature gradient in the eastern United States.

Functional traits (wood density, specific leaf area and maximum height) interacted with individual size and temperature to influence tree growth, survival and recruitment rates, generating demographic trade‐offs and shaping the contours of fitness landscapes. Tall tree species had high survival, growth and fitness across the temperature gradient. Wood density and specific leaf area had interactive effects on demographic performance, resulting in fitness landscapes with multiple peaks.

With this approach it is now possible to empirically estimate the net effect of traits on fitness, leading to an improved understanding of the selective forces that drive community assembly and permitting generalizable predictions of population and community dynamics in changing environments.
Incidence of bradycardia during noradrenaline or phenylephrine bolus treatment of postspinal hypotension in cesarean delivery: A randomized double‐blinded controlled trial
Authors: de Queiroz Daniel Vieira , Velarde Luis Guillermo Coca , Alves Rodrigo Leal , Verçosa Nubia , Cavalcanti Ismar Lima
Published: March 2023

The treatment of choice for spinal anesthesia‐induced hypotension during cesarean section is phenylephrine. As this vasopressor can cause reflex bradycardia, noradrenaline is a suggested alternative. This randomized double‐blinded controlled trial included 76 parturients undergoing elective cesarean delivery under spinal anesthesia. Women received noradrenaline in bolus doses of 5 mcg or phenylephrine in bolus doses of 100 mcg. These drugs were used intermittently and therapeutically to maintain systolic blood pressure ≥ 90% of its baseline value. The primary study outcome was bradycardia incidence (<60 bpm) with intermittent bolus administration of these drugs. Secondary outcomes included extreme bradycardia (<40 bpm), number of bradycardia episodes, hypertension (systolic blood pressure > 120% of baseline value), and hypotension (systolic blood pressure < 90% of baseline value and requiring vasopressor use). Neonatal outcomes per the Apgar scale and umbilical cord blood gas analysis were also compared. The incidence of bradycardia in both groups (51.4% and 70.3%, respectively; p = 0.16) were not significantly different. No neonates had umbilical vein or artery pH values below 7.20. The noradrenaline group required more boluses than phenylephrine group (8 vs. 5; p = 0.01). There was no significant intergroup difference in any of the other secondary outcomes. When administered in intermittent bolus doses for the treatment of postspinal hypotension in elective cesarean delivery, noradrenaline, and phenylephrine have a similar incidence of bradycardia. When treating hypotension related to spinal anesthesia in obstetric cases, strong vasopressors are commonly administered, thought these can also have side effects. This trial assessed bradycardia after bolus administration of noradrenaline or phenylephrine, and found no difference in risk for clinically meaningful bradycardia.
Therapists' first impression of treatment motivation moderates the relationship between the client‐rated therapeutic alliance and drinking outcomes during treatment
Authors: Rivera Alexander P. , Maisto Stephen A. , Connors Gerard J. , Schlauch Robert C.
Published: March 2023

Introduction

First impressions can influence interpersonal relationships for extended periods, with negative first impressions leading to more negative judgments and behaviors between individuals months after their initial meeting. Although common factors such as therapeutic alliance (TA) are well studied, less is known of the potential influence of a therapist's first impression of their client's motivation on TA and drinking outcomes. Based on data from a prospective study of the perceptions of the TA among clients receiving cognitive‐behavioral treatment (CBT), this study examined how therapists' first impressions may moderate the relationship between client‐rated TA and drinking outcomes during treatment.

Methods

One hundred fifty‐four adults participated in a 12‐week course of CBT and completed measures of TA and drinking behaviors following each treatment session. Additionally, therapists completed a measure of their first impression of their client's motivation for treatment following the first session.

Results

Time‐lagged multilevel modeling revealed a significant within‐person TA by therapists' first impression interaction that predicted percent days abstinent (PDA). Specifically, among participants rated as lower on first impressions of treatment motivation, higher within‐person TA predicted greater PDA in the interval prior to the next treatment session. Within‐person working alliance was not associated with PDA among individuals rated higher on first impressions of treatment motivation who demonstrated higher PDA throughout treatment. Furthermore, significant between‐person TA by first impressions interactions were found for both PDA and drinks per drinking day (DDD), such that among individuals with lower treatment motivation, TA positively predicted PDA and negatively predicted DDD.

Conclusion

Although therapists' first impressions of a client's treatment motivation are positively associated with treatment outcomes, clients' perception of the TA may mitigate the impact of poor first impressions. These findings highlight the need for additional nuanced examinations of the relationship between TA and treatment outcomes, emphasizing the contextual factors that influence this relationship.
Solar‐powered cold‐storage and agrifood market modernization in Nigeria
Authors: Takeshima Hiroyuki , Yamauchi Futoshi , Edeh Hyacinth O. , Hernandez Manuel A.
Published: March 2023

Modern cooling technologies that utilize renewable energy sources have been increasingly recognized as promising tools to address various challenges emerging in progressively complex agrifood systems in developing countries. Knowledge gaps about the actual impacts of these technologies in developing countries remain, especially in Africa south of the Sahara (SSA). This study fills this knowledge gap by providing evidence from the evaluation of recent interventions in northeast Nigeria in which seven small solar‐powered cold storages were installed across seven horticulture markets. Combinations of difference‐in‐difference (DID) and variants of propensity‐score‐based methods suggest that cold storage significantly increased horticulture sales volumes and revenues of market agents. Back‐of‐the‐envelope calculations indicate that increased net revenues for market agents may be sufficiently large to recoup cold storage investments and operating costs within a reasonable time frame. Using cold storage also reduced the share of food loss. It lengthened the products' shelf‐life while raising prices received by market agents and farmers, which were associated with improved product quality, expanded value‐adding activities by market agents, and increased use of advance payments.
The effectiveness of continuous positive airway pressure for treating obstructive sleep apnoea in pregnancy: A systematic review
Authors: Nugent Rachael , Wee Amanda , Kearney Lauren , de Costa Caroline
Published: March 2023

Background

Obstructive sleep apnoea (OSA) occurs in 15–20% of pregnant women living with obesity. As global obesity prevalence increases, OSA in pregnancy is concurrently increasing, yet remains under‐diagnosed. The effects of treating OSA in pregnancy are under‐investigated.

Aim

A systematic review was conducted to determine whether treating pregnant women with OSA using continuous positive airway pressure (CPAP) will improve maternal or fetal outcomes, compared with no treatment or delayed treatment.

Materials and Methods

Original studies in English published until May 2022 were included. Searches were conducted in Medline, PubMed, Scopus, the Cochrane Library and clinicaltrials.org. Maternal and neonatal outcome data were extracted, and quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach (PROSPERO registration: CRD42019127754).

Results

Seven trials met inclusion criteria. Use of CPAP in pregnancy appears to be well tolerated with reasonable adherence. Use of CPAP in pregnancy may be associated with both a reduction in blood pressure and pre‐eclampsia. Birthweight may be increased by maternal CPAP treatment, and preterm birth may be reduced by treatment with CPAP in pregnancy.

Conclusion

Treatment of OSA with CPAP in pregnancy may reduce hypertension and, preterm birth, and may increase neonatal birthweight. However, more rigorous definitive trial evidence is required to adequately assess the indication, efficacy, and applications of CPAP treatment in pregnancy.
Improved fertility of frozen‐thawed porcine spermatozoa with 3,3‐dimethylglutaric anhydride poly‐L‐lysine as a novel cryoprotectant
Authors: Jin Hansol , Choi Wooyoon , Matsumura Kazuaki , Hyon Suong‐hyu , Gen Yuki , Hayashi Masakazu , Kawabata Tadahiro , Ijiri Moe , Miyoshi Kazuchika
Published: March 2023

In this study, we determined the efficacy of 3,3‐dimethylglutaric anhydride poly‐L‐lysine (DMGA‐PLL) as a cryoprotectant for porcine spermatozoa. Porcine spermatozoa were cryopreserved in a freezing extender containing 3% (v/v) glycerol and various concentrations of DMGA‐PLL. At 12 h after thawing, the motility index of spermatozoa cryopreserved with 0.25% (v/v) DMGA‐PLL (25.9) was significantly (P < 0.01) higher than that of spermatozoa cryopreserved with 0%, 0.125%, or 0.5% DMGA‐PLL (10.0–16.3). In addition, the blastocyst formation rate of embryos derived from spermatozoa cryopreserved with 0.25% DMGA‐PLL (22.8%) was significantly (P < 0.01) higher than that of embryos derived from spermatozoa cryopreserved with 0%, 0.125%, or 0.5% DMGA‐PLL (7.9%–10.9%). The mean number of total piglets born to sows inseminated with spermatozoa cryopreserved without DMGA‐PLL (9.0) was significantly (P < 0.05) lower than that of total piglets born to sows inseminated with spermatozoa stored at 17°C (13.8). However, when spermatozoa cryopreserved with 0.25% DMGA‐PLL were used for artificial insemination, the mean number of total piglets (11.7) was not significantly different from that obtained following artificial insemination using spermatozoa stored at 17°C. The results showed the usefulness of DMGA‐PLL as a cryoprotectant in the cryopreservation of porcine spermatozoa.
How state influence on project work organization both drives and mitigates gendered precarity in cultural and creative industries
Authors: Pulignano Valeria , Dean Deborah , Domecka Markieta , Vermeerbergen Lander
Published: March 2023

This article develops an understanding of gendered precarity in project work by considering how the transfer of risk from employer to worker is shaped by the contextual pressures of state policy and the organization of the industrial field. The focus is the organization of project work as a condition underpinning the shifting of this risk in a mature field of precarious employment, the cultural and creative industries (CCIs). Our empirical exploration in Film/TV in the UK and Germany, and Dance in Sweden and the Netherlands, examines the dynamic interplay between state policy domains (cultural, social and regulatory), industry‐level funding bodies or ‘transaction organizers’ and the cultural processes of CCI project networks. We argue that state‐led influences both drive and mitigate the transfer of risk in project work as gendered, racialized and classed. Our framework contributes to broadening employment literature on risk and the disadvantaging capacity of networks to hoard opportunities in project‐based labour markets.

Creativity and Innovation Management has grown substantially over the last couple of years, both quantitatively and qualitatively. From 2016 to 2021, the number of submissions has grown from 287 to 395. Most of the growth was realized in Asia: The number of submissions from that continent increased from 72 in 2016 to 193 in 2021. The rest of the world remained (close to) stable: 215 in 2016 and 203 in 2021. Equally important, the Thomson ISI Impact Factor increased from 1.423 in 2015 to 3.051 in 2021 and further to 3.644 in 2022. This is not where our ambitions end, though. We want to be the ever‐better outlet for authors researching, and practitioners working in, the fields we cover. Editing a journal with the ambition to continuously increase its quality while dealing with a substantial growth requires teamwork—teamwork among the editors and the editorial office, teamwork between the editors and their reviewers and, as surprising as this may sound, teamwork between the authors and their reviewers in a top‐quality reviewing process. The purpose of this piece is to present and discuss some reviewing standards. In particular, we aim to share with our reviewers what we think is an excellent reviewing process. Furthermore, we formulate our ideas about what it is that makes a review an excellent one. The title of this piece is deliberately ambiguous. It denotes that Creativity and Innovation Management strives for reviewing excellence—as in an excellent reviewing process. It also denotes that we reach for the stars and hope to one day receive and, hence, review only excellent submissions.

Females present a higher risk of adverse drug reactions. Sex‐related differences in drug concentrations may contribute to these observations but they remain understudied given the underrepresentation of females in clinical trials. The aim of this study was to investigate whether anthropometric and socioeconomic factors and comorbidities could explain sex‐related differences in concentrations and dosing for metoprolol and oxypurinol, the active metabolite of allopurinol. We conducted an analysis of two cross‐sectional studies. Participants were self‐described “White” adults taking metoprolol or allopurinol selected from the Montreal Heart Institute Hospital Cohort. A total of 1007 participants were included in the metoprolol subpopulation and 459 participants in the allopurinol subpopulation; 73% and 86% of the participants from the metoprolol and allopurinol subpopulations were males, respectively. Females presented higher age‐ and dose‐adjusted concentrations of both metoprolol and oxypurinol (both p < 0.03). Accordingly, females presented higher unadjusted and age‐adjusted concentration:dose ratio of both metoprolol and allopurinol/oxypurinol compared to males (all p < 3.0 × 10−4). Sex remained an independent predictor of metoprolol concentrations (p < 0.01), but not of oxypurinol concentrations, after adjusting for other predictors. In addition to sex, age, daily dose, use of moderate to strong CYP2D6 inhibitors, weight, and CYP2D6 genotype‐inferred phenotype were associated with concentrations of metoprolol (all p < 0.01). Daily dose, weight, estimated glomerular filtration rate (eGFR), and employment status were associated with oxypurinol concentrations (all p < 0.01). Females present higher dose‐adjusted concentrations of metoprolol and oxypurinol than males. This suggests the need for sex‐specific dosing requirements for these drugs, although this hypothesis should be validated in prospective studies.

Aim

To examine adjustment after stroke in adolescence from the perspective of affected young people.

Method

Fourteen participants (10 female) aged 13 to 25 years with a history of ischemic or hemorrhagic stroke in adolescence participated in one‐on‐one semi‐structured interviews at the Hospital for Sick Children, Toronto, Canada. Interviews were audio‐recorded and transcribed verbatim. Two independent coders conducted a reflexive thematic analysis.

Results

Five themes were identified as representative of adjustment after stroke: (1) ‘Processing the story’; (2) ‘Loss and challenges’; (3) ‘I've changed’; (4) ‘Keys to recovery’; and (5) ‘Adjustment and acceptance’.

Interpretation

This qualitative study provides medical professionals with a personal, patient‐driven lens through which to better understand the challenges of adjusting to life after pediatric stroke. Findings highlight the need to provide mental health support to patients to assist them in processing their stroke and adapting to long‐lasting sequelae.

What this paper adds

Processing the onset event is a key component of adjustment to stroke.

Feelings of anxiety, sadness, frustration, and self‐consciousness impede adjustment to stroke.

Young people may feel overwhelmed academically owing to neurocognitive deficits.

Sequelae may rid young people of hobbies and passions, and alter plans for the future.

To adjust to stroke, survivors draw on resilience, patience, determination, and social support.
In plateaus, land cover replaced climate as the vital environmental factor on the spatial composition of bumblebees with the altitude rising

Bumblebees show a series of advantages over other pollinating insects in offering pollination services for both the ecosystem and agricultural production, especially in high‐altitude areas. With climate warming, their diversity at high altitudes will be threatened. Therefore, more attention should be paid to the management of bumblebee resources at high altitudes to prevent their decline here. Discovering drivers responsible for the spatial variation of biodiversity is a benefit for developing appropriate management.

Here, based on the bumblebee diversity on three plateau areas with an altitude gradient, the roles of different environmental factors, the climate, land cover, topography, habitat heterogeneity and soil, in the bumblebee composition were assessed by generalised dissimilarity modelling. And the relative importance of variables was evaluated by the impact on the magnitude of total biological change and the per cent change in deviance explained by models.

According to the results, in the low‐altitude area, the climate played a vital role and the most important variable was the climate variable. Then, with the altitude rising, the effect of land cover continually increased. In the medium‐altitude area, the effects of different factors were detected to be similar, and the most important variables were a climate variable and a land cover variable. In the high‐altitude area, land cover finally replaced the climate as the most important factor, and one land cover variable was assessed as the most important variable. Our study revealed that the relative importance of different environmental factors on the biodiversity of bumblebees can differ as the altitude rises.
Out with the old and in with the new: Preventing child opioid addiction through over‐the‐counter medications
Authors: Akl Ashley L.
Published: March 2023

Opioids are killing America's youth. New data confirms that children under 18 who are prescribed opioids by a medical doctor develop a heightened risk of future drug addiction. Currently, there are no national prescribing guidelines for opioids in the pediatric population. However, doctors recently started to administer an over‐the‐counter medicine combination of Advil and Tylenol to patients because it is more effective at relieving pain than prescription opioids and prevents addiction. Thus, drafting national legislation to limit the circumstances under which a child is eligible to receive an opioid prescription will save countless children from a life of future addiction.
