The ‘discontinuity hypothesis’ of depression in later life—clinical and research implications
Authors: Oude Voshaar Richard C
Published: December 2023

The term depression is overused as an umbrella term for a variety of conditions, including depressed mood and various psychiatric disorders. According to psychiatric diagnostic criteria, depressive disorders impact nearly all aspects of human life and are a leading cause of disability worldwide. The widespread assumption that different types of depression lie on a continuum of severity has stimulated important research on subthreshold depression in later life. This view assumes that depressed mood is a precursor of a depressive disorder. The present narrative review argues why in later life depressed mood might either (i) lie on a continuum with depressive disorders among people vulnerable for a depressive disorder or (ii) be an ageing-related epiphenomenon of underlying physical illnesses in people who are resilient to depressive disorders (‘discontinuity hypothesis’). Three arguments are discussed. First, the course of depressed mood and depressive disorders differs across the life span. Second, screening instruments for depression have low predictive value for depressive disorders in later life. Third, a dose–response relationship has not been consistently found across different types of depression and detrimental health outcomes. Using the umbrella term depression may partly explain why pharmacological treatment is less effective with increasing age, and negative health-related outcomes might be overestimated. The discontinuity hypothesis may prevent pharmacological overtreatment of milder subtypes of depression and may stimulate comprehensive multidisciplinary assessment as well as the development of separate treatment algorithms for depressed mood and depressive disorders.

Published: December 2023

Background

Ampullary carcinoma is a clinically variable entity. This study aimed to evaluate prognostic factors for the outcome of resected ampullary carcinoma patients with particular intent to analyse the influence of surgical radicality.

Methods

Patients undergoing resection between 2002 and 2017 were analysed. Clinicopathological parameters, perioperative outcome and survival were examined. Risk factor analysis for postresection survival was performed. Resection margin status was evaluated according to the revised classification for pancreatic adenocarcinoma.

Results

A total of 234 patients were identified, 97.9 per cent (n = 229) underwent formal resection, while 2.1 per cent (n = 5) underwent ampullary resection. Histological subtypes were 46.6 per cent (n = 109) pancreatobiliary, 34.2 per cent (n = 80) intestinal, 11.5 per cent (n = 27) mixed, and 7.7 per cent (n = 18) undetermined. In the pancreatobiliary group, tumours were more advanced with more vascular resections, pT4 stage, G3 differentiation and pN+ status. Five-year overall survival was significantly different for pancreatobiliary compared to intestinal (51.7 per cent versus 72.8 per cent, P = 0.0087). In univariable analysis, age, pT4 stage, pN+, pancreatobiliary subtype and positive resection margin were significantly associated with worse overall survival. Long-term outcome was significantly better after true R0 resection (circumferential resection margin–, tumour clearance >1 mm) compared with circumferential resection margin+ (<1 mm) and R1 resections (5-year overall survival: 69.6 per cent, median overall survival 191 months versus 42.4 per cent and 53 months; P = 0.0017).

Conclusion

Postresection survival of ampullary carcinoma patients is determined by histological subtype and surgical radicality. Intestinal differentiation is associated with less advanced tumour stages and better differentiation, which is reflected in a significantly better overall survival compared to pancreatobiliary differentiation. Despite this, true R0-resection is a prognostic key determinant in both entities, achieving 5-year survival in two-thirds of patients.
Evolution is more repeatable in the introduction than range expansion phase of colonization
Authors: Tittes Silas , Weiss-Lehman Christopher , Kane Nolan C , Hufbauer Ruth A , Emery Nancy C , Melbourne Brett A
Published: December 2023

How repeatable is evolution at genomic and phenotypic scales? We studied the repeatability of evolution during 8 generations of colonization using replicated microcosm experiments with the red flour beetle, Tribolium castaneum. Based on the patterns of shared allele frequency changes that occurred in populations from the same generation or experimental location, we found adaptive evolution to be more repeatable in the introduction and establishment phases of colonization than in the spread phase, when populations expand their range. Lastly, by studying changes in allele frequencies at conserved loci, we found evidence for the theoretical prediction that range expansion reduces the efficiency of selection to purge deleterious alleles. Overall, our results increase our understanding of adaptive evolution during colonization, demonstrating that evolution can be highly repeatable while also showing that stochasticity still plays an important role.
Coupled poroelastic and gravitational deformation of a layered spherical Earth – I: load Love numbers
Authors: Zhou Jiangcun , Pan Ernian , Bevis Michael , Xu Jianqiao , Sun Heping
Published: December 2023

In this paper, we propose a fully coupled two-phase poroelastic deformation theory for a spherically layered and self-gravitating Earth. The earth model consists of a solid inner core, a fluid outer core and poroelastic mantle and crust. The boundary-value problems are posed in the Laplace-transformed domain using the spherical system of vector functions, and analytical solutions are obtained in each layer using the dual-variable and position matrix method. As an application, the surface loading problem is considered. The undrained and drained limits are discussed with the corresponding governing equations, which are different from the conventional ones where body force is ignored. Numerical examples show that the poroelastic effect can be significant since the difference between the results for undrained and drained limits are large with obvious time-dependent deformation. This newly derived theory for the coupled boundary-value problem will have broad applications, such as displacement and gravity change due to groundwater depletion, poroelastic rebound after an earthquake and risk evaluation of earthquakes induced by water injection.

Lean healthcare visual management has been successfully integrated into infection control programs, leading to lower healthcare-associated infection (HAI) rates and greater provider compliance with evidence-based prevention practices; however, its implementation during quality improvement (QI) initiatives in limited-resource settings has not yet been well exploited. We aimed to describe a low-cost strategy involving Kamishibai cards to sustain bundles’ adherence to prevent HAIs in a middle-income country. This descriptive case study evaluated the implementation of a lean healthcare visual management tool—Kamishibai board (K-board)—during a nationwide QI collaborative preventing three critical HAIs in 189 adult and pediatric/neonatal intensive care units (ICUs) from September 2021 to January 2023. Considering a limited-resource setting, our team adapted a K-board using simple, cheap, and easy-to-handle materials for routine monitoring of QI procedures, including safety bundles’ compliance. After test prototypes, the final K-board version was implemented. The chart materials and assembly cost BRL 80.00 (USD 15.48). Before launching, expert working group meetings were held to shape the contents, refine technical issues, and prepare the ICU teams for implementation. After starting, plan-do-study-act cycles were conducted according to the Breakthrough Series model. Participating ICU teams, including leaders and front-line health workers, performed bedside audits following a weekly chronogram. Two indicators were calculated: the percentage of ICUs in which K-boards were being implemented and whether bundles’ compliance was addressed in the K-board. Audit data were recorded in ‘SimpleQI’. After 17 months of this initiative, 177 (93.7%) participating ICUs had included this visual management tool in their daily care routines. When more than 94 (>50%) ICUs posted K-board data, the mean compliance for the bundles for each HAI was sustained above 85%. A lean healthcare visual management tool can be adapted to local settings, including healthcare facilities with limited resources. K-board seems to be a feasible method for auditing evidence-based practices in medical care, including safety bundles to simultaneously prevent three types of HAIs.
Best practice: quality assessment outcomes of the Practice Enhancement Program among family physicians in Saskatchewan, Canada
Authors: Macaskill James , Bryce Rhonda , Muller Andries
Published: December 2023

Increased family physician workloads have strained primary care. The objective of this study was to describe the frequency and types of quality concerns identified among Saskatchewan’s family physicians, changes in these concerns over time, associated physician characteristics, and recommendations made for improvement. In this repeated cross-sectional study (1997–2020), we examined family physician assessment reports from the Saskatchewan Practice Enhancement Program, a mandatory practice review strategy, for quality concerns on three outcomes: care, medical record, and facility. We recorded demographic and practice characteristics, the presence or absence of quality concerns, and the type of recommendations made. Concern incidence was calculated both overall and across subperiods, and three outcome-specific multiple logistic regression models were developed. Recommendations made were quantified, and their nature was evaluated using thematic analysis. Among 824 assessments, 20.8% identified concerns, with a statistically significant increase in 2015–20 over earlier years (14.2% versus 43.4%, P < .001). Corresponding proportions also significantly increased within each quality outcome (6.0%–37.1%, P < .001 for care concerns; 12.7%–19.6%, P = .03 for medical record concerns; 3.9%–21.0%, P < .001 for facility concerns). We found statistically significant adjusted associations between care concerns and both urban location [odds ratio (OR): 2.2; 95% confidence interval (CI): 1.30, 3.8] and international medical training (OR: 2.4; 95% CI: 1.34, 4.2); facility concerns and solo practice (OR: 2.5 95% CI: 1.10, 5.7); and medical record concerns and male gender (OR: 1.88; 95% CI: 1.09, 3.3), solo practice (OR: 1.67; 95% CI: 1.01, 2.7), and increased age. Reflecting a statistically significant interaction found between age as a continuous covariate and time period, older physicians were more likely to have a medical record concern in later years (OR: 1.072; 95% CI: 1.026, 1.120) compared to earlier ones (OR: 1.021; 95% CI: 1.001, 1.043). Among physicians where a concern was identified, recommendations most frequently pertained to documentation (91.2%), chronic disease management (78.2%), cumulative patient profiles (62.9%), laboratory investigations (53.5%), medications (51.8%), and emergency preparedness (51.2%). A concerning and increasing proportion of family physicians have quality gaps, with identifiable factors and recurring recommendations. These findings provide direction for strategic support development.
Multidisciplinary perspectives on roles of hospital pharmacists in tertiary settings: a qualitative study
Authors: Lee Kyung Min Kirsten , Koeper Ivanka , Johnson Michaela E , Page Amy , Rowett Debra , Johnson Jacinta
Published: December 2023

In today’s complex healthcare landscape, exacerbated by resource constraints at various levels, optimization of health professionals’ roles is becoming increasingly paramount. Interprofessional collaboration, underpinned by role recognition and teamwork, leads to improved patient and organizational outcomes. Hospital pharmacists play a pivotal role in multidisciplinary teams, and it is imperative to understand multidisciplinary viewpoints on hospital pharmacists’ roles to guide role prioritization and organizational efficiency. However, no study extensively investigated multidisciplinary views on values of diverse pharmacist roles in tertiary settings. This study aims to address this gap by examining non-pharmacist health professionals’ views on hospital pharmacists’ roles, recognizing their specialized niches as a crucial step towards optimizing their roles and services in Australia and internationally. Multiple focus group discussions and interviews were held via a virtual conferencing platform. Study participants were recruited using the study investigators’ professional networks who were non-pharmacist health professionals with experience working with pharmacists in hospital settings. Data were collected from transcripts of the focus group recordings, which were later summarized using descriptive statistics and thematic analysis. Overarching themes were categorized and mapped against work system models to conceptualize organizational implications of multidisciplinary feedback, linking them to patient and organizational outcomes. Twenty-seven health professionals participated across focus groups and interviews, with the majority of professions being doctors and nurses. Three major themes were identified as follows: (i) overarching perceptions regarding hospital pharmacists; (ii) professional niches of hospital pharmacists; and (iii) future opportunities to optimize hospital pharmacy services. Valued professional niches included patient and health professional educators, transition-of-care facilitators, and quality use of medicines analysts. The study highlights critical insights into hospital pharmacists’ roles in Australia, identifying their niche expertise as vital to healthcare efficiency and success. Based on multidisciplinary feedback, the study advocates for strategic role optimization and targeted research for enhanced clinical, economic, and organizational outcomes.
Process reengineering using DMAIC framework for reduction of waiting time in daycare infusion therapy for better patient experience
Authors: Mamballikalam Gopinath , Davis Deena , Sabrish K G
Published: December 2023

Daycare infusion therapy is an integral aspect of oncology, but increased waiting time raises concerns for patients. Patient-reported experience measures prompted the need to evaluate reasons for prolonged appointment delays. This study seeks to analyze and address patients’ concerns, to streamline the process flow and reduce waiting time for daycare infusion therapy thereby enhancing patient experience. The define, measure, analyze, improve, and control methodology was implemented, and its impact on reducing waiting times was evaluated. The objective is to ensure that >85% of patients enter the daycare infusion unit within an hour of their appointment time in 6 months. The baseline data for patient waiting times was measured for a period of 2 months, and the average waiting time was determined. Potential causes contributing to prolonged waiting times were identified through time-motion analysis, with a fishbone diagram categorizing potential causes and a Pareto chart prioritizing them. Plan, do, study, and act cycles were conducted for implementing the changes, and a new process flow mapped. Baseline data showed 32% average adherence to the defined turnaround time of 1 hour, with an average waiting time of 108 minutes. Forty causes were identified for increased waiting time, of which eight were key. Adherence to waiting time turnaround time improved from 32% to 89% and the average waiting time decreased by 59 minutes from 108 minutes, increasing patient satisfaction index by 7.5%. The balancing measures include an increase in operational efficiency and throughput of the unit and the inventory levels of oncology medicine were decreased, leading to a 50% reduction in inventory value, while medication error declined by 0.62%, improving patient safety. The project gained tangible and intangible benefits impacting staff, patients, and relatives while improving operational efficiency. This study, with its scientific and systematic approach, enhanced patient satisfaction, patient safety, and better utilization of resources.

Aims

To examine the diversity of Staphylococcus aureus isolated from nasal swabs of ruminants in Rwanda.

Methods and results

A total of 454 nasal swabs from 203 cows, 170 goats, and 81 sheep were examined for the presence of S. aureus, and 30 S. aureus isolates were detected and characterized pheno- and genotypically. Resistance to penicillin and/or tetracycline was observed. The isolates were assigned to eight different spa types (t21057 (novel), t10103, t18853, t20842, t318, t355, t458, and t9432) belonging to six clonal complexes (CCs) (CC152, CC30, CC3591, CC3666, CC522, and CC97). Panton–Valentine leukocidin (PVL) genes (lukF-PV/lukS-PV), the bovine leukocidin genes (lukM/lukF-P83), and the human and bovine variants of the toxic shock syndrome toxin gene tst-1 variants were detected.

Conclusion

These findings demonstrate that the nares of ruminants in Rwanda are colonized with mastitis-associated S. aureus, including lineages that are also carried by humans, underscoring the zoonotic risk, especially for livestock keepers. These results highlight the crucial importance of hygiene measures when handling livestock.
Searching for quasar candidates with periodic variations from the Zwicky Transient Facility: results and implications

Published: December 2023

We conduct a systematic search for quasars with periodic variations from the archival photometric data of the Zwicky Transient Facility by cross-matching with the quasar catalogues of the Sloan Digital Sky Survey and Véron-Cetty and Véron. We first select out 184 primitive periodic candidates using the generalized Lomb–Scargle periodogram and autocorrelation function and then estimate their statistical significance of periodicity based on two red-noise models, i.e. damped random walk (DRW) and single power-law (SPL) models. As such, we finally identify 106 (DRW) and 86 (SPL) candidates with the most significant periodic variations out of 143 700 quasars. We further compare DRW and SPL models using Bayes factors, which indicate a relative preference of the SPL model for our primitive sample. We thus adopt the candidates identified with SPL as the final sample and summarize its basic properties. We extend the light curves of the selected candidates by supplying other archival survey data to verify their periodicity. However, only three candidates (with 6–8 cycles of periods) meet the selection criteria. This result clearly implies that, instead of being strictly periodic, the variability must be quasi-periodic or caused by stochastic red-noise. This exerts a challenge to the existing search approaches and calls for developing new effective methods.
Distinguishing the impact and signature of black holes from different origins in early cosmic history
Authors: Zhang Saiyang , Liu Boyuan , Bromm Volker
Published: December 2023

We semi-analytically model the effects of primordial black hole (PBH) accretion on the cosmic radiation background during the epoch of reionization (z ≳ 6). PBHs in the intergalactic medium (IGM) and haloes, where star formation can occur, are considered. For stars with a mass $\gtrsim 25 \rm \ {\rm M}_{\odot }$, formed in suitable host haloes, we assume they quickly burn out and form stellar-remnant black holes (SRBHs). These SRBHs, like PBHs, also accrete material, and are considered to have similar radiation feedback in the halo environment. To improve the background radiation estimation, we consider the impact of PBHs on structure formation, allowing a modified halo mass function. We consider the radiation feedback from a broad suite of black holes: PBHs, SRBHs, high-mass X-ray binaries, and supermassive black holes. The result shows that at z ≳ 30, the radiation background energy density is generated by PBHs accreting in the IGM, whereas at lower redshifts, halo accretion dominates. We also dissect the total power density by modelling the accretion spectral energy distribution across different wavebands. In the UV band, we find that for fPBH ≲ 10−3, the H-ionizing and Lyman-α fluxes from PBH accretion feedback do not violate existing constraints on the timing of reionization, and on the effective Wouthuysen–Field coupling of the 21-cm spin temperature of neutral hydrogen to the IGM kinetic temperature. However, in the X-ray band, with the same abundance, PBHs contribute significantly and could explain the unresolved part of the cosmic X-ray background.
Do ultra diffuse galaxies with rich globular clusters systems have overly massive haloes?
Authors: Forbes Duncan A , Gannon Jonah
Published: December 2023

Some Ultra Diffuse Galaxies (UDGs) appear to host exceptionally rich globular cluster (GC) systems compared to normal galaxies of the same stellar mass. After re-examining these claims, we focus on a small sample of UDGs from the literature that have both rich GC systems (NGC >20) and a measured galaxy velocity dispersion. We find that UDGs with more GCs have higher dynamical masses and that GC-rich UDGs are dark matter dominated within their half-light radii. We extrapolate these dynamical masses to derive total halo masses assuming cuspy and cored mass profiles. We find reasonable agreement between halo masses derived from GC numbers (assuming the GC number–halo mass relation) and from cored halo profiles. This suggests that GC-rich UDGs do not follow the standard stellar mass–halo mass relation, occupying overly massive cored haloes for their stellar mass. A similar process to that invoked for some Local Group dwarfs, of early quenching, may result in GC-rich UDGs that have failed to form the expected mass of stars in a given halo (and thus giving the appearance of overly an massive halo). Simulations that correctly reproduce the known properties of GC systems associated with UDGs are needed.
Changes in Glomerular Filtration Rate After Switching From Tenofovir Disoproxil Fumarate to Tenofovir Alafenamide Fumarate for Human Immunodeficiency Virus Preexposure Prophylaxis
Authors: Rivera Adovich S , Pak Katherine , Mefford Matthew T , Hechter Rulin C
Published: December 2023

Background

Tenofovir alafenamide fumarate (TAF) was promoted as a safer alternative to tenofovir disoproxil fumarate (TDF) for human immunodeficiency virus oral preexposure prophylaxis (PrEP). It is unknown if switching from TDF to TAF translates to improved renal function. We used electronic health record (EHR) data to assess changes in creatinine-estimated glomerular filtration rate (eGFR) after switching from TDF to TAF.

Methods

We conducted a retrospective cohort study using EHR data from Kaiser Permanente Southern California. We identified individuals who switched from TDF to TAF between October 2019 and May 2022 and used time-varying propensity score matching to identify controls who were on TDF (“nonswitchers”). We then used Bayesian longitudinal modeling to compare differences in eGFR between switching and nonswitching scenarios.

Results

Among 5246 eligible individuals, we included 118 TDF to TAF switchers and 114 nonswitchers. Compared to nonswitchers, switchers had older age of starting TDF but similar body weights at index date. A higher proportion of switchers were White, on Medicare or Medicaid, and had dyslipidemia at index date. Switching to TAF was associated with a higher eGFR compared to staying on TDF in 3–15 months post-switch, but the differences were not statistically significant (eg, month 9 difference: 1.27 [95% credible interval, −1.35 to 3.89]). While most of the estimated changes showed eGFR increase associated with switching, most were <2 eGFR units. Sensitivity analyses to address missingness or nonadherence showed similar results.

Conclusions

Switching from TDF to TAF for PrEP was associated with a nonsignificant increase in eGFR. Findings need to be confirmed using larger cohorts.
EEG and computational aspects of how aging affects sleep slow waves
Authors: El Kanbi Karim , Tort-Colet Nuria , Benchenane Karim , Destexhe Alain
Published: December 2023

Sleep slow-waves have been reported to vary with age in human subjects, as well as in mouse, but the underlying mechanisms remain unclear. Here, we perform a precise quantification of the effect of aging on the shape and dynamics of sleep slow waves, in a large cohort of human subjects recorded with the electro-encephalogram (EEG) during sleep. The fine-structure analysis of slow waves reveals that they slow-down, increase of variability and decrease in amplitude with age. We next investigate a computational model of the genesis of slow-wave activity and model the aging by a global decrease of the strength of the external excitatory drive to the network. This simple model reproduces some of the main features observed in the EEG, suggesting that changes of long-range excitatory connection strength may explain the evolution of slow-waves with age.
Bibliometric analysis and scientific mapping of research trends on ‘digital divide’
Authors: Tyagi Sunil
Published: December 2023

Purpose

With the aid of bibliometric analysis, this study aims to show the state-of-the-art of research on the digital divide and identifies new areas for further investigation.

Design/methodology/approach

Performance analysis and science mapping were used in the study to analyse a sample of 3,571 studies that were published between 2018 and 2022. The “Title-Keyword-Abstract” search option was used to collect the anticipated publications data from the Scopus database. The gathered data were analysed using the common bibliometric indices to evaluate the research landscape. The science mapping tactics made use of the VOSviewer and Biblioshiny software.

Findings

The performance and science mapping analysis shows that recent research on the digital divide has not been sufficiently exposed and examined. The analysis discovered emerging topics, prolific authors and nations, affiliations, a network of collaboration among authors, countries and institutions, bibliographic coupling and keyword co-occurrence.

Originality/value

This work presents a state-of-the-art that has significant theoretical and practical ramifications for the existing digital divide literature. The methodologies and database used in the current study are more extensive.
Developing a multifunctional wearable system consisting of a helmet and clothing for two-wheeled vehicle users' safety assistance
Authors: Kim Younghwan , Lee Hyunseung
Published: December 2023

Purpose

This study aims to develop a safe, wearable clothing system that combines visibility-enhancing and emergency–accident-responding functions for two-wheeled vehicle (TWV) users' safety assistance.

Design/methodology/approach

First, the wearable system (WS) allowing users to control turn signals, brake lights and emergency flasher only with head movements was developed. Second, multiconnected systems were developed between WSs and a smartphone application (AS), providing accident occurrence recognition, driving photo capture–storage and emergency notification functions. Third, usability testing in each function was performed to assess the operability of the systems.

Findings

The intuitive interface, which uses head movement as gesture commands, was effectively operated for controlling turn signals, brake lights and emergency flasher when driving, despite differences in user physique and boarding structure among TWVs. In addition, using Bluetooth low energy and Wi-Fi protocols simultaneously can establish automatic accident recognition–notification and driving photo capture–storage–display functions by linking two WSs with one AS.

Research limitations/implications

This study presents a case using relatively accessible technologies within the fashion industry to improve users' safety and provide fundamental data for convergence education for smart fashion products, highlighting the significance of this study in this convergence era.

Originality/value

The WSs and the AS of a TWV user visually evoke the attention of other drivers and pedestrians, reducing the risk of accidents; social contribution regarding public safety will be possible by allowing the system to autonomously inform emergencies and receive emergency medical treatment quickly when the accident occurred.
University language students’ evaluations of ecological, social, cultural and economic sustainability and their importance in language teaching
Authors: Kuusalu Salla-Riikka , Laine Päivi , Maijala Minna , Mutta Maarit , Patzelt Mareen
Published: December 2023

Purpose

This study aims to explore how university language students evaluate different sustainability themes and examine the overall relevance of ecological, social, cultural and economic sustainability dimensions in language education.

Design/methodology/approach

A questionnaire was designed to study Finnish university language students’ (n = 55) order of priority for sustainability dimensions and their sub-themes and the justifications for the priority orders using a mixed methods design. Qualitative content analysis was conducted using NVivo software, and weighted rankings were used to analyse the quantitative data.

Findings

The findings of the study showed that language students evaluated the social and cultural dimensions as the most relevant in language teaching. In all dimensions, students approached sustainability mainly by prioritising larger issues and advancing towards smaller ones. Most non-directional responses appeared in the economic dimension. In addition, individual prioritising and justification approaches varied between different sustainability dimensions.

Originality/value

To the best of the authors’ knowledge, no previous studies have examined language students’ evaluations of and justifications for all four sustainability dimensions. The results highlight the need to use multiple, holistic approaches and systems thinking to incorporate education for sustainable development.
Buying centers and emerging developments: the SME perspective
Authors: Cardinali Silvio , Sharma Piyush , Cedrola Elena , Giovannetti Marta , Pillai Kishore Gopalakrishna
Published: December 2023

Purpose

This paper aims to explore the challenges and opportunities faced by buying centers in small and medium enterprises (SME) manufacturing companies in view of recent technological changes and the virtualization of communication.

Design/methodology/approach

This study uses a qualitative approach with multiple case studies to portray complex realities within the buying centers in the manufacturing SME context. The authors selected five Italian companies to portray the diverse characteristics, practices and policies of relevant stakeholders before reaching saturation with the issues explored.

Findings

The authors find that interactions among buying center members are more effective with greater collaboration and exchange (as opposed to competition and a struggle for power). Virtual/hybrid relations require greater intra-group cooperation, whereas diverse backgrounds and collaborative interactions help the flexibility and performance of the buying center. Greater use of technology produces certainty and automation, but it may also cause overload and biases that can be solved with the ability to analyze and clear responsibility for decisions.

Research limitations/implications

The authors studied only five Italian companies in this study. Future research in other countries with diverse cultural and socio-economic conditions and methods would help extend this research.

Practical implications

The findings would improve the understanding of the challenges of adopting new purchase process technologies that would help automate routine tasks, produce useful data and support decision-making.

Originality/value

Unlike prior studies, this study uses an exploratory design to study the evolution of buying centers in SMEs to seek deeper insights into the challenges and opportunities faced by SMEs because of the growing use of emerging technologies.
Integrating time and knowledge to understand organizational evolution: towards a conceptual framework
Authors: Paniccia Paola Maria Anna , Abatecola Gianpaolo , Baiocco Silvia
Published: December 2023

Purpose

How does the interaction between time and knowledge affect the evolution of organizations? Past research in organizational evolution has mostly investigated time and knowledge as two separate variables. In contrast, theoretical perspectives integrating these variables are still seemingly scant. The authors believe that filling this literature gap needs attention. Thus, this study aims to contribute by developing a conceptual framework.

Design/methodology/approach

This is a conceptual study. The framework is centred on the concept of “co-evolutionary time”, which the authors explain through a business example from the tourism industry. Supported by a narrative-based style, from a methodological point of view the framework is featured by the attempt to synthesize specific, extant literature into new theoretical development.

Findings

As its main theoretical contribution, the co-evolutionary time suggests how firms can adapt in a way that, from an evolutionary perspective, proves fitting both in terms of contents and methods, thus opening possibilities for new long-term social construction and reconstruction. As its main practical contribution, co-evolutionary time can constitute not only a temporary source of organizational success and competitive advantage but also an agent of enduring change and long-term business survival.

Originality/value

As its main novelty, the framework is developed through merging two literature streams. In particular, the authors first consider the literature about time, with a focus on its objective and subjective dimensions. The authors then consider the literature about organizational evolution, with a focus on the co-evolutionary nature of the firm/environment relationship.

Published: December 2023

Purpose

This study aims to explore browsing extension plugins for searching open scholarly literature and gain an understanding of the various available extensions, their functionalities and their benefits.

Design/methodology/approach

Published: December 2023

Purpose

This study aims to better understand the morphological characteristics of single particle and the health risk characteristics of heavy metals in PM2.5 in different functional areas of Handan City.

Design/methodology/approach

High resolution transmission electron microscopy was used to observe the aerosol samples collected from different functional areas of Handan City. The morphology and size distribution of the particles collected on hazy and clear days were compared. The health risk evaluation model was applied to evaluate the hazardous effects of particles on human health in different functional areas on hazy days.

Findings

The results show that the particulate matter in different functional areas is dominated by spherical particles in different weather conditions. In particular, the proportion of spherical particles exceeds 70% on the haze day, and the percentage of soot aggregates increases significantly on the clear day. The percentage of each type of particle in the teaching and living areas varied less under different weather conditions. Except for the industrial area, the size distribution of each type of particle in haze samples is larger than that on the clear day. Spherical particles contribute more to the small particle size segment. Soot aggregate and other shaped particles contribute more to the large size segment. The mass concentrations of hazardous elements (HEs) in PM2.5 in different functional areas on consecutive haze pollution days were illustrated as industrial area > traffic area > living area > teaching area. Compared with the other functional areas, the teaching area had the lowest noncarcinogenic risk of HEs. The lifetime carcinogenic risk values of Cr and As elements in each functional area have exceeded residents’ threshold levels and are at high risk of carcinogenicity. Among the four functional areas, the industrial area has the highest carcinogenic and noncarcinogenic risks. But the effects of HEs on human health in the other functional areas should also be taken seriously and continuously controlled.

Originality/value

The significance of the study is to further understand the morphological characteristics of single particles and the health risks of heavy metals in different functional areas of Handan City. the authors hope to provide a reference for other coal-burning industrial cities to develop plans to improve air quality and human respiratory health.
Individual differences in holistic word processing and the role of phonological processing in sentence comprehension
Authors: Hirshorn Elizabeth A. , Reilly Emma , Louche‐Robert Alison , Wojszysnki Cody
Published: December 2023

Background

Recent research has documented individual differences in the reading profiles of skilled native English readers using a behavioural marker of holistic visual word processing (orientation sensitivity). A more holistic word reading profile is associated with a weaker correlation with phonological decoding for word identification. Interestingly, that is different from typical patterns in skilled reading in English. The current study aimed to further assess the underlying distribution of orientation sensitivity as a continuous measure in an unrestricted undergraduate population and to extend past findings to understand the role of phonological decoding in reading comprehension as a function of orientation sensitivity.

Methods

A group of 137 SUNY New Paltz undergraduates completed an orientation sensitivity test to assess the overarching distribution. A subset of 55 SUNY New Paltz undergraduates completed additional reading‐related tests (phonological decoding and reading comprehension) on an online platform (findingfive.com). The relationship between orientation sensitivity and reliance on phonological decoding on reading comprehension was assessed using regression.

Results

Results found that the distribution of orientation sensitivity was not normal and skews to the right, but is not bimodal, thus warranting the use of regression instead of group statistics. Lastly, those with relatively greater orientation sensitivity had a weaker relationship between measures of phonological decoding and a reading comprehension measure, as predicted.

Conclusions

The results extended the finding of differences in reliance on phonological decoding to reading comprehension as a function of orientation sensitivity. These results help refine our understanding of orientation sensitive readers and potential alternative route to successful reading found in the general population.
