Cardiorespiratory fitness is associated with cognitive performance in 80 + -year-olds: Detangling processing levels
Authors: Fröhlich Stephanie , Kutz Dieter F. , Müller Katrin , Voelcker-Rehage Claudia 
Published: January 2024

AbstractCardiorespiratory fitness is known to protect against cognitive decline in older adults. Specifically, it has been shown that physical activity and fitness are beneficial for executive functions that are crucial for independent living up to old age. In this study, 115 individuals aged 80 years and older underwent a cardiorespiratory fitness assessment using the two-minute step test and had their electroencephalogram recorded during a colored flanker task in order to measure executive function performance. Cardiorespiratory fitness was related to quicker responses during the flanker task. A mediation analysis was carried out to determine whether these positive effects were mediated through event-related potentials (N1, N2, or P3) or motor-related cortical potentials (MRCP). Cardiorespiratory fitness was related to better visual discriminative processing as indicated by larger occipital N1 amplitudes. In addition, fitness was associated with larger MRCP amplitudes, which are a correlate of the response generation process. Fitness was not found to have a significant effect on fronto-central N2 or parietal P3, which are thought to capture cognitive control processes such as conflict detection and response inhibition. Moreover, all effects reported were present in all three flanker trial conditions (congruent, neutral, and incongruent). Thus, these results indicate that the quicker response times in fitter people were related to visual processing and motor response generation rather than cognitive control.

Published: January 2024

AbstractComplex digitalization and sustainability challenges shape today’s management agendas. To date, the dedication of Information Systems research to both challenges has not been equal in terms of effort and reward. Building capabilities to leverage the synergetic potential of digital and sustainability transformation may enhance organizational performance and imply new value creation for the common good. To uncover such synergetic potential, this work conceptualizes the “twin transformation” construct as a value-adding reinforcing interplay between digital transformation and sustainability transformation efforts that improve an organization by leveraging digital technologies to enable sustainability and to guide digital progress by leveraging sustainability. The twin transformation conceptualization is complemented with a capability framework for twin transformation drawing from dynamic capability theory. This work contributes to descriptive knowledge of the interplay between digital transformation and sustainability transformation, setting a foundation for further theorizing on twin transformation and enabling organizations to twin transform.
Determination of metal fractions and rare earth anomalies in red mud: the case of bauxite mining district of Seydişehir (Turkey)
Authors: Çelebi Emin Ender 
Published: January 2024

AbstractA three-step sequential extraction was carried out by modified BCR approach for fractionation of metals, including rare earths in red mud. Acetic acid leaching, hydroxylamine hydrochloride + nitric acid leaching, hydrogen peroxide + acid ammonium acetate leaching, and orthophosphoric + nitric acid digestion in microwave were performed to determine ion exchangeable (F1), reducible (F2), oxidizable (F3), and residual (F4) fractions of metals, respectively. Accordingly, the highest readily soluble phases were obtained for Ca, Na, and K, while the reducible were Al, Zn, Cu, and Li. Rare earth elements (REEs) except for Eu were mostly identified in residual fraction. Most of Eu (88.7%) was detected in the reducible fraction, while the negligible part in residual. Chondrite normalization was implemented for obtaining REE anomalies. The remarkable Eu and Gd negative anomaly differences were determined between the red mud and its origin, Mortaş bauxite. The LREE to HREE ratio and LaN/YbN scores of 8.42 and 7.82, respectively indicated the LREE enrichment to HREE. By performing multivariate analysis, six and five-group clusters were obtained for REEs and non-REE metals in terms of fractional distribution, proving the easier release potential of Eu, La, Gd, K, Na, and Ca.

AbstractPreparing catalysts from cheap metal precursors in a single pot are an appealing method for reducing catalytic preparation costs, minimizing chemical waste, and saving time. With regards to the catalytic conversion of dry reforming of methane, it offers the prospect of significantly reducing the cost of H2 production. Herein, NiO-stabilized metal oxides like Ni/TiO2, Ni/MgO, Ni/ZrO2, and Ni/Al2O3 are prepared at two different calcination temperatures (600 °C and 800 °C). Catalysts are characterized by X-ray diffraction, Raman spectroscopy, surface area-porosity analysis, Temperature program experiments, infrared spectroscopy, and thermogravimetry analysis. The MgO-supported Ni catalyst (Ni/MgO-600), ZrO2-supported Ni catalyst (Ni/ZrO2-600), and Al2O3-supported Ni (Ni/Al2O3-600) catalyst calcined at 600 °C show initial equal H2 yields (~ 55%). The population of CH4 decomposition sites over ZrO2-supported Ni catalyst remains highest, but H2-yield drops to 45% against high coke deposition. The catalytic activity remains constant over the Ni/MgO-600 catalyst due to the enrichment of “surface interacted CO2-species”. MgO-supported Ni catalyst calcined at 800 °C undergoes weak interactions of NiO-M′ (M′ = support), serious loss of CH4 decomposition sites and potential consumption of H2 by reverse water gas shift reaction, resulting in inferior H2 yield. H2-yield remains unaffected over an Al2O3-supported Ni catalyst even against the highest coke deposition due to the formation of stable Ni (which exsolves from NiAl2O4) and proper matching between carbon formation and rate of carbon diffusion.
Greatest common divisor results on semiabelian varieties and a conjecture of Silverman
Authors: Barroero Fabrizio , Capuano Laura , Turchet Amos

AbstractA divisibility sequence is a sequence of integers $$\{d_n\}$$

{

}

such that $$d_m$$

d

divides $$d_n$$

d
n

if m divides n. Results of Bugeaud, Corvaja, Zannier, among others, have shown that the gcd of two divisibility sequences corresponding to subgroups of the multiplicative group grows in a controlled way. Silverman conjectured that a similar behaviour should appear in many algebraic groups. We extend results by Ghioca–Hsia–Tucker and Silverman for elliptic curves and prove an analogue of Silverman’s conjecture over function fields for abelian and split semiabelian varieties and some generalizations of this result. We employ tools coming from the theory of unlikely intersections as well as properties of the so-called Betti map associated to a section of an abelian scheme.
Understanding the Relationship Between Immigration and Innovation: A Systematic Review and Meta-Analysis
Authors: Capoani  , Chabert  , Izzo  
Published: January 2024

AbstractThe relationship between immigration and innovation has become an urgent topic of discussion in the USA and in the European Union due to the current migration patterns and the crucial role played by innovation as a driver of growth in modern economies. The present study is a systematic review regarding the investigation of the status of the research on immigration, ethnic diversity, and their impact on innovations, especially at the firm’s organisational level. With a focus on high-skilled immigrants, a closer examination of the link between migration and economic performance of the private sector has been conducted during the research. The paper will focus on the elements that impact the contributions of migrants towards the total level of innovation of host countries. Cultural diversity, demographic agglomeration forces, and the educational backgrounds of newcomers are identified as drivers of innovation which influence patenting activity. Additionally, the research provides an overview of the positive influence of migration on innovation spillovers, taking into account its ability to isolate the channels concerning education history and labour supply that lead to this beneficial effect. The evidence suggests that immigrants contribute to the overall level of economic growth and innovation in destination countries, as spillovers of entrepreneurial capabilities and scientific and technological knowledge appear to be fundamental to innovation in host countries. Nonetheless, policy-makers are presented with expected outcomes, as well as no evidence to suggest that migration is detrimental to a strong research and development sector.

AbstractIn this study, published articles on the adsorptive removal of tartrazine from the aqueous phase were reviewed. Adsorbents sustaining both intercalating and photodegradation characteristics were also assessed. Besides collating available information on adsorbents employed for tartrazine removal, experimental conditions (solution temperature, pH, dosage, initial concentration, and agitation period) relating to the adsorptive removal of tartrazine were discussed. Deduction from kinetic, isotherms and thermodynamics data acquired from different adsorbents were assessed. Granular activated carbon and chitosan adsorbents had the least and highest tartrazine removal capacity. Lower solution pH majorly favoured the adsorption of tartrazine. On the other hand, increased dosage, contact time, initial concentration, and solution temperature generally enhanced the adsorptive uptake of tartrazine. Pseudo-second-order kinetics model was observed to typically describe the kinetic data. Freundlich and Langmuir isotherm models were popularly observed to best describe the tartrazine adsorption equilibrium. The uptake of tartrazine was generally spontaneous with the exception of a few nanocomposites. Meanwhile, π-π stacking, hydrogen bonding, Van der Waals forces and electrostatic interactions were proposed as possible mechanisms for the adsorption of tartrazine from wastewater. Adsorbents demonstrated good regeneration tendency with NaOH. Hence, it was concluded that the batch adsorption technique is economically viable and should be scaled up for industrial applications. Meanwhile, future work on tartrazine adsorption should employ real wastewater samples, regenerate adsorbents for reuse, design and execute a pilot scale assessment, employ column adsorption technique and formulate policy to regulate effluent discharge.
The role of hope and conservation attitudes in current conservation actions and future conservation intentions

Published: January 2024

AbstractCurrent community-led conservation (CLC) actions support present and future biodiversity. Present-day conservation volunteer efforts are measurable; however, future CLC activity is uncertain. Understanding what motivates volunteers to take part in CLC activities is therefore essential. This study investigates the relationships between hope, conservation attitudes, current conservation action, and future conservation intention. We use Snyder’s adult hope state scale to explore the relationship between hope, conservation attitudes, self-reported current conservation actions, and future conservation intentions (planting, weeding, predator control) of 243 adult Aotearoa New Zealand participants. The relationship of hope and conservation attitudes to current conservation action and future conservation intention is complex. Specifically, hope relates to future conservation intention but is not associated with current conservation action. Furthermore, hope negatively correlated with intending volunteer belief that nature could heal itself. Volunteers with future conservation intentions hold conservation attitudes that actively connect people to nature and other people and show commitment to the natural world. Intending volunteers also feel able to help others learn about the natural world, value scientific and technological interventions, and the relative importance of individual effort, teamwork, and collaboration. Volunteers currently active in conservation solely held attitudes of connection to nature, connection to other people, commitment to the natural world, and helping others learn about the natural world. Understanding what motivates volunteers to undertake conservation action is critical to designing sustainable CLC projects that deliver positive outcomes for biodiversity in the long term.

Published: January 2024

Abstract
Background
Fundamentally, there are several levels of complexities associated with the digitalization of the agriculture sector. In the context of the Indian agricultural sector, the contemporary efforts towards E-Governance are helping a progressive digitization process to be realized through the comprehensive National E-governance Plan for Agriculture (NeGP-A), one of the Indian government's Multimodal Projects (MMPs). The cornerstone of the recent digital push in agriculture through the India Digital Ecosystem of Agriculture (IDEA) framework is Digital AgriStack, an amalgamation of digital technologies and databases concentrating on farmers and the agricultural industry.

Purpose
Intriguingly, there is just a handful of explorative research to gain in-depth ideas on administrative efforts regarding E-governance activities in the Indian agricultural sector. Hence, a stringent effort has been made to cover all facets of E-government in Indian agriculture, beginning with its inception, advancement, and present status as well as a synergy between the center and the states across the domains of G2G, G2F, G2B, and B2F, for the first time.

Findings
The review presents a comprehensive list of the E-governance initiatives categorized across the four domains of governance and draws a clear picture of the Indian state of e-governance in agriculture while presenting the advancements and challenges at a global and local scale.

Originality
To the best of our knowledge, no such rigorous attempt has previously been made to analyze and comprehensively present as well as categorize the Indian E-governance facets in the agricultural sector. This will certainly add to the emerging knowledge in the respective E-gov agricultural domains and their applications in developing nations across the globe.

AbstractDepression and anxiety are prevalent mental health issues worldwide, especially among parental caregivers. By expanding the family stress model, this cross-sectional study investigated the relevant factors associated with depressive symptoms, anxiety symptoms, and satisfaction with life among Malaysian parental caregivers of adolescent psychiatric patients. Data were collected through questionnaires (N= 207) across five major public hospitals through convenience sampling. Participants answered questionnaires measuring financial strain, caregiver burden, relationship quality, belief in mental illness, perceived COVID-19 stress, satisfaction with health services, depressive symptoms, anxiety symptoms and life satisfaction. Findings revealed that relationship quality among spouses, COVID-19 stress and caregiver burden were significantly correlated with anxiety symptoms, depressive symptoms and satisfaction with life. The multiple regression model also suggested that depressive symptoms (β= .613,p< .001), anxiety symptoms (β= .657,p< .001) and relationship quality among spouses (β= .264,p< .001) were the most influential predictors of anxiety symptoms, depressive symptoms and satisfaction with life respectively. By addressing the mental health needs of parental caregivers, this study can contribute to improving the overall quality of care and support provided to adolescent patients and their caregivers in Malaysia and beyond.

Abstract
The current study assessed the views and attitudes of health professionals (HPs) regarding factors associated with energy balance-related health behaviours and weight management in breast cancer survivors (BCS) with overweight and obesity. Semi-structured online interviews were conducted with 21 HPs (oncologists, dietitians- nutritionists, physical education instructors, mental health professionals, and nurses) from Attica and Thessaly. Thematic analysis was used to analyse and present the data. Four main themes arose from the data: “The patients’ mental health wellbeing”, “Survivors’ interest in diet and exercise”, “Interdisciplinary collaboration in patient’s care”, and “Maintaining normality”. HPs agreed that weight loss in BCS with overweight and obesity is important, but negative mental health wellbeing is a main barrier to behaviour change. For many BCS their cancer diagnosis is a “teachable” moment for weight management, especially for women of younger age, who are more keen to discuss weight management issues. Essential characteristics that determine/facilitate behavioural change include education, commitment for regular communication, personalised intervention, and interdisciplinary collaboration. According to HPs, future weight loss interventions should take into account BCS’s mental health wellbeing and level of motivation and should provide regular support and education.
Approximation with ergodic processes and testability
Authors: Loh Isaac 
Published: January 2024

AbstractWe show that stationary time series can be uniformly approximated over all finite time intervals by mixing, non-ergodic, non-mean-ergodic, and periodic processes, and by codings of aperiodic processes. A corollary is that the ergodic hypothesis—that time averages will converge to their statistical counterparts—and several adjacent hypotheses are not testable in the non-parametric case. Further Baire category implications are also explored.

Published: January 2024

Abstract
This study verified the diagnostic accuracy of the nutritional status classified by the international height and BMI references of the World Health Organization (WHO) (WHO/2007), International Obesity Task Force (IOTF/2012) and MULT (2023). The data pool was composed by 22 737 subjects aged five to 16 years from the Santos and Porto Alegre surveys. A correlation matrix between the z-scores of the BMI references and the skinfold measurements was calculated through the Pearson correlation coefficient (r), and the subject’s nutritional status was classified according to the international growth references. The accuracy for diagnosing obesity was performed separately by sex and using the 95th percentile of the triceps and subscapular skinfold sum, while Lin’s concordance coefficient, Bland–Altman method and the Cohen’s Kappa coefficient (Kappa) were used to verify the concordance and reliability among the BMI references. The correlation matrix showed a high positive correlation among the BMI z-scores (r ≥ 0·99) and among the skinfold measurements (r ≥ 0·86). The prevalence of stunting was higher when applying the MULT reference (3·4 %) compared with the WHO reference (2·3 %). The Bland–Altman plots showed the lowest critical difference (CD) between the height references of WHO and MULT (CD = 0·22). Among the BMI references, the WHO obesity percentile presented lower performance than MULT for boys, presenting a lower +LR value (WHO = 6·99/MULT 18 years = 10·99; 19 years = 8·99; 20 years = 8·09) for the same −LR values (0·04). Therefore, MULT reference holds promise as a valuable tool for diagnosing childhood obesity, particularly when considering sex differences. This enhances its suitability for assessing the nutritional status of Brazilian schoolchildren.
