Anecdotal Evidence Elucidates the Aging Process.

Our group at Yuvan Research has conducted several experiments in recent years that have demonstrated the reversibility of aging through the use of a young plasma fraction, following a historical line of research that began with heterochronic parabiosis. However, a one-of-a-kind discovery, in the form of anecdotal evidence, has recently clarified many doubts about the nature of aging and rejuvenation, and the conclusions that can be drawn from this discovery allow us to form a relatively clear picture of the mechanics of the aging and rejuvenation processes.

Overview of the Balanced Suspension Patents

Background: The suspension has the role of transmitting and carrying the forces and moments between the wheels and the frame and controlling the wheel runout, thus providing the car with good comfort and operational stability. Objective: Through the analysis of the current situation of suspension research, we summarize the research line and specific technical solutions of suspension, and finally, we provide an outlook on the future development direction of suspension, which in turn can provide some reference value for readers. Methods: The existing suspensions are classified into passive suspensions, semi-active suspensions, and active suspensions, and their improvement methods are described to compare the advantages and disadvantages of different improvement methods. Results: By comparing the results of suspension studies, semi-active suspension can effectively improve the smoothness and handling stability of the vehicle. Semi-active suspension has the advantages of low energy consumption, simple control, lower cost, easy implementation, and high reliability, while the effect of vibration control can be close to active suspension to some extent and far better than passive suspension. Conclusion: This paper introduces passive suspension, semi-active suspension, and active suspension in three categories and describes the working principle, functions, problem-solving advantages, and shortcomings of the three suspensions, respectively. Semi-active suspension is more suitable for the future development trend of suspension.

Linguistic Acceptability

Abstract: This article is about linguistic acceptability, and in this article, linguistic acceptability is treated as a synonym of textual acceptability. This article has as fundamental objective to understand the factors that contribute to the establishment of linguistic acceptability, and to continue this study, the starting question was the following: What are the factors that contribute to the establishment of linguistic acceptability? Therefore, to answer this question, the line of bibliographical research was adopted as a methodology in order to understand the different perspectives linked to this theme in order to understand and comprehend the determining conditions that contribute to textual acceptability in a given communicative event. In this way, it is understood that this article can substantially contribute to raising awareness among potential speakers of a language about the essential criteria that guarantee textual acceptability, but also about its relevance in the language teaching and learning process. Thus, in view of the above, it is concluded that textual acceptability is characterized by the ability of the receiver to attribute a certain meaning to the linguistic sequences produced by his interlocutor, there are several criteria that must be mobilized, relevant for example for linguistic knowledge, sociolinguistic knowledge and pragmatic knowledge, that is, the learner of a given language must simultaneously master linguistic conventions and sociocultural conventions on the use of language within the speaking community

Taming a wild new term: exploring the concept of quiet quitting as a coping response

Purpose“Quiet quitting” emerged as a term in the US during the COVID-19 pandemic and has since gained immense popularity worldwide, working its way into common usage. However, disagreement exists over the term’s meaning and utility. Our paper critically considers the value of the construct of quiet quitting, proposing an initial operationalization of its properties.Design/methodology/approachWe develop hypotheses related to the antecedents, characteristics and consequences of quiet quitting through a literature review and subsequent survey. The questionnaire was distributed to working professionals in Europe and assessed through multiple partial least squares analyses.FindingsWe propose quiet quitting as a coping strategy involving a combination of reduced effort, disengagement, disassociation and boundary-setting. 108 responses obtained through a survey of knowledge workers provide some support that these existing concepts indeed form a second-order construct with emergent properties not found when assessed individually. However, we suggest that the utility of quiet quitting as a distinct coping strategy is questionable and that generally, it is more useful to discuss its subcomponents separately.Research limitations/implicationsWhile limited by its cross-sectional nature, this work raises several potentially fruitful future lines of research and offers a first step in evaluating a relatively new term that is of substantial relevance to management scholarship and practice.Originality/valueNew concepts stemming from popular literature can be problematic, grounded in untested folk theory and riddled with ambiguity. At the same time, they can stretch our thinking and drive research in new directions if they can be sufficiently refined. We offer a new conceptualization of quiet quitting but question its usefulness.

A convolution inequality, yielding a sharper Berry–Esseen theorem for summands Zolotarev-close to normal

The classical Berry–Esseen error bound, for the normal approximation to the law of a sum of independent and identically distributed random variables, is here improved by replacing the standardised third absolute moment with a weak norm distance to normality, using Zolotarev’s ζ \zeta norms. We thus sharpen and simplify two results of Ul’yanov (1976) and of Senatov (1998), each of them previously optimal, in the line of research initiated by Zolotarev (1965) and Paulauskas (1969). Our proof is based on a seemingly incomparable normal approximation theorem of Zolotarev (1986), combined with our main technical result: The Kolmogorov distance (supremum norm of difference of distribution functions) between a convolution of two laws and a convolution of two Lipschitz laws is bounded homogeneously of degree 1 in the pair of the Kantorovich distances (often called Wasserstein distances, the L 1 ^1 norms of differences of distribution functions) of the corresponding factors, and also in the pair of the Lipschitz constants. Side results include a short introduction to ζ \zeta norms on the real line, simpler inequalities for various probability distances, slight improvements of the theorem of Zolotarev (1986) and of a lower bound theorem of Bobkov, Chistyakov and Götze (2012), an application to sampling from finite populations, auxiliary results on rounding and on winsorisation, and computations of a few examples. The introductory section in particular is aimed at analysts in general rather than specialists in probability approximations.

Promising Neuroscience Methods in Exploring the Spatiotemporal Mechanisms underlying Speech Motor Control

Speech motor control is a complex neuromotor behavior that requires the combined efforts of feedforward control and feedback control subsystems. With the advent of neuroscience, multiple lines of research have explored the spatiotemporal mechanisms underlying this process. The purpose of this review was to point out several promising neuroscience methods and their unique values in enriching the speech motor control literature. We discussed the clinical value of noninvasive brain stimulation methods, and the theoretical value of invasive brain recording methods, as well as the predictive value of brain connectivity techniques. Based on prior findings, we propose a roadmap for future research, identifying structure-function coupling that supports speech motor control.

Evolution and relevance of research on Environmental, Social, and Governance factors

AbstractIn the wake of a compelling societal shift and the subsequent widespread response across multiple industries, Environmental, Social, and Governance (ESG) factors have emerged as a pivotal subject in scholarly literature. To gauge the significance of these contributions and facilitate objective exploration in future research, we employ bibliometric techniques. Thus, we identify the relevant authors and journals, and depict the evolution in the themes and pillars of the intellectual framework underpinning the topic. Our analysis covers 594 articles from 2007 to 2022, divided into two distinct periods. In the first period, the pillars are centered on contextualizing theories, the impact in terms of financial‐related performance, and the ethical implications within the domain of corporate social responsibility. In the subsequent period, there is a notable progression towards reinforcing theoretical foundations. The pillars shift towards more practical implications, focusing on challenges associated with investing based on ESG criteria, guiding stakeholders in adapting to this paradigm, and addressing risks tied to its implementation. Financial performance, disclosure in reporting, and socially responsible investments remain crucial matters, and the analysis of the environmental issues outnumber social, and governance ones in both periods. We discuss the potential implications and further lines of research.

Generation of Triplet States by Host‐Stabilized Through‐Space Conjugation for the Construction of Efficient Supramolecular Photocatalysts

AbstractPromoting the generation of triplet states is essential for developing efficient photocatalytic systems. This research presents a novel approach of host‐stabilized through‐space conjugation via the combination of covalent and non‐covalent methods. The designed building block, 4,4′‐(1,4(1,4)‐dibenzene cyclohexaphane‐1,4‐diyl)bis(1‐phenylpyridinium) chloride, features inherently stable through‐space conjugation. When this block forms a 1 : 1 host–guest complex with cucurbit[8]uril, the through‐space conjugation is further stabilized within the confined cavity. Both the generation and lifetime of triplet state are significantly increased, resulting from the host‐stabilized through‐space conjugation. Additionally, the ultrahigh binding constant of 6.58×1014 M−1 ensures the persistence of host‐stabilization effect. As a result, the host–guest complex acts as a highly efficient catalyst in the photocatalytic oxidation of thioether and aromatic alcohol. In the photodegradation of lignin, a complex natural product, the host–guest complex also exhibits high efficiency, demonstrating its robustness. This line of research is anticipated to enrich the toolbox of supramolecular photochemistry and provide a strategy for fabricating efficient supramolecular photocatalysts.

Research on cyberbullying and suicide: a bibliometric analysis

AbstractSuicide is a global mental health problem. In recent years, suicidal ideation, suicide attempts and suicides have increased in children and adolescents. In this population, cyberbullying is a public health problem that has grown along the increase in use of devices with internet access. Cybervictimization is related to negative health effects, even including suicidal ideation or suicide in cyberbullied individuals. This study is the first bibliometric analysis on scientific literature related to cyberbullying and suicide based on the traditional laws of bibliometrics. The aim was to generate a global overview of the research related to this object of study. We analysed 242 documents published in journals indexed in the Web of Science, examining the trend followed by annual publications, identifying the prolific (most productive) and prominent (prolific co‐authors with one or more papers between most cited papers) co‐authors, leading countries and journals, the most cited documents and the most used author keywords. Annual publications followed an exponential growth trend (R2 = 89.2%), meaning that there is a great interest in the scientific community for this study object. International Journal of Environmental Research and Public Health and Psychiatry Research were the journals with most document published. Baiden, P. (prolific), Kowalski, R. (most cited), Hinjuja, S. and Patchin, J. (prominents) were the most highlighted co‐authors, reference authors on the subject. Most scientific output originated in the USA. Five thematic lines were identified among the author keywords. The results of this research show the growing interest of the scientific community in this topic, along with useful information for researchers and publishers, identifying relevant co‐authors, journals interested in the topic and emerging lines of research, highlighting self‐harm, cyber‐victimisation, suicide risks and suicidal behaviours as the most recent thematic lines.

Anatomical Connectivity Constrains Dynamic Functional Connectivity among Neural Systems: Implications for Cognition and Behavior

Abstract Leslie Ungerleider had a tremendous impact across many different areas of cognitive neuroscience. Her ideas and her approach, as well as her findings, will continue to impact the field for generations to come. One of the most impactful aspects of her approach was her focus on the ways that anatomical connections constrain functional communications among brain regions. Furthermore, she emphasized that changes in these functional communications, whether from lesions to the anatomical connections or temporary modulations of the efficacy of information transmission resulting from selective attention, have consequences for cognition and behavior. By necessity, this short review cannot cover the vast amount of research that contributed to or benefited from Leslie's work. Rather, we focus on one line of research that grew directly from some of Leslie's early work and her mentoring on these important concepts. This research and the many other lines of research that arose from these same origins has helped develop our understanding of the visual system, and cognitive systems more generally, as collections of highly organized, specialized, dynamic, and interacting subsystems.

When TCM debate meets Covid-19 discourse

Abstract The Covid-19 pandemic has pushed medical discourse to the forefront of everyday communication, but limited scholarly attention has been given to its intersection with social-mediated language use in the Chinese context. From a corpus-pragmatic view, we examined textual data collected from Zhihu, the most popular Chinese community question-answering site. Our analysis focused on the linguistic mechanism of evidential expression in social-mediated debates on Traditional Chinese medicine (TCM). Within the realm of medical scientific discussion, we identified a prevailing epistemic stance of doubt and uncertainty towards the efficacy of TCM, emphasising its socio-political significance. We also demonstrated how the ‘source of knowledge’ value and the ‘speaker commitment’ value of evidentiality interact at the semantic-pragmatic interface. Our findings shed light on a promising research trajectory for sociolinguistic intervention in the formal, descriptive line of evidentiality research, thus, advancing existing corpus pragmatics literature on evidentiality and epistemics in social-mediated communication.

In addition, the results are profitable from a professional standpoint. Organizations in the tourism sector may reflect on and promote best practices in developing emotional and positive affect skills among their service staff given their influence on customer satisfaction. Originality/Value: This study contributes to the literature as scientific research on this subject remains scarce. Furthermore, the results can have an impact on the performance of tourism businesses and thus on the economic development of the destination.

Barriers to seeking counseling among US military service members

AbstractA stigma toward accessing mental health support services exists in military culture. One of the next steps in this line of research is gaining a better understanding of the barriers or reasons behind why service members can be reluctant to seek counseling. We recruited a national sample (N = 516) of service members to test the dimensionality of scores on the Revised Fit, Stigma, and Value (RFSV) Scale for measuring barriers to seeking counseling. Results demonstrated that the meaning of RFSV scores was invariant by help‐seeking history (past attendance in counseling) and by mental health diagnosis. After establishing adequate construct validity evidence of scores, we found that the Value barrier was a significant predictor of one or more peer‐to‐peer referrals to counseling among service members. Additionally, demographic differences in the Value and Stigma barriers emerged by help‐seeking history and active duty status, respectively.

Effectiveness of Omega-3 Fatty Acids Versus Placebo in Subjects at Ultra-High Risk for Psychosis: The PURPOSE Randomized Clinical Trial.

In the past 2 decades, substantial effort has been put into research on therapeutic options for people at ultra-high risk (UHR) for developing a first episode of psychosis (FEP), focusing on omega-3 polyunsaturated fatty acids (PUFAs) in preventing transition to psychosis. Despite an initial positive finding, subsequent studies failed to find a beneficial effect. The current study aimed to further investigate the effect of omega-3 PUFAs in UHR, to determine whether this line of research is worth pursuing. A double-blind, randomized, placebo-controlled study testing the efficacy of 6-month treatment with omega-3 PUFAs in 135 subjects at UHR for FEP, aged 13 to 20 years on the prevention of a transition to psychosis, followed up for 18 months post-treatment. The trial was conducted at 16 general hospitals and psychiatric specialty centers located in 8 European countries and Israel. There was no beneficial effect of treatment with omega-3 PUFAs compared to placebo; the rate of transition over 2 years did not differ between treatment arms nor was there a difference in change in symptom severity after 6-month treatment. Dropout rates and serious adverse events were similar across the groups. This is the third study that fails to replicate the original finding on the protective effect of omega-3 PUFAs in UHR subjects for transition to psychosis. The accumulating evidence therefore suggests that omega-3 PUFAs do not reduce transition rates to psychosis in those at increased risk at 2 years follow-up. This trial is registered with ClinicalTrials.gov (NCT02597439; Study Details | Placebo-controlled Trial in Subjects at Ultra-high Risk for Psychosis With Omega-3 Fatty Acids in Europe | ClinicalTrials.gov).

To Seek or Not to Seek? An Assessment of Partisan Media Avoidance and Its Correlates

ABSTRACT Scholars have noted the importance of studying avoidance of partisan media. However, most partisan media studies have only included measures of seeking out these sources of information and assume that avoidance is operationally measured as a lack of use of partisan media. Some scholars have argued that avoidance is conceptually distinct, so assessing avoidance as a lack of use may not be the best approach to measuring avoidance. In this paper, we extend this line of research by demonstrating that our measures of active partisan avoidance are separate concepts from use of these same outlets. Using two data sets and confirmatory factor analysis, our results reveal that models where use and avoidance are treated as separate concepts fit the data better than when these concepts are treated as one factor. We also evaluate the validity of these measures. In general, this study suggests that scholars may want to consider assessing avoidance when studying this concept rather than just assessing use.

Research on the Cognitive Orientation to daily Occupational Performance Approach: A Bibliometric Review.

The Cognitive Orientation to daily Occupational Performance (CO-OP) is an evidence-based intervention approach that has significantly increased in popularity over the past two decades. However, how the research literature on this topic is patterned is still unknown, so it is difficult to identify potential areas for research and clinical interest. To analyze the literature published on the CO-OP approach to provide a detailed and structured analysis of the publication patterns. All literature related to CO-OP included in the Web of Science database through June 15, 2024. All published studies related to CO-OP were included in the bibliometric analysis, which was conducted on the raw data retrieved from the Web of Science database using the Bibliometrix R package. The annual growth rate in CO-OP research has been 0.8%, significantly increasing from 2015 onward. Most of the research has been published in occupational therapy and rehabilitation journals by English-speaking research teams, and its scope has expanded from developmental coordination disorder to a wide range of health conditions. In addition, two main lines of research have emerged: one focusing on understanding the underlying cognitive processes involved in CO-OP and the other focusing on its clinical effectiveness. Research on CO-OP has significantly increased over the past decade, and it currently encompasses a wide range of areas. This analysis may facilitate the advancement of research on and the clinical practical application of CO-OP. Plain-Language Summary: The Cognitive Orientation to daily Occupational Performance (CO-OP) is an evidence-based intervention approach that has significantly increased in popularity over the past two decades. Occupational therapists use it to improve the occupational performance of both children and adults with movement difficulties. However, it is unknown how the research literature on this topic is patterned, so it is difficult to identify potential areas for research and clinical interest. This study found that scientific literature on CO-OP has significantly increased in the past decade and that its scope has expanded from developmental coordination disorder to a wider range of health conditions, such as cerebral palsy. Moreover, research is now focused on two main questions: What are the underlying cognitive processes involved during intervention, and how effective is the CO-OP approach? These findings can be used to further improve occupational performance and participation among occupational therapy clients who struggle with motor performance and planning.

Dialect levelling and merchant writing in Renaissance Italy

Abstract This article aims to assess the extent to which merchant language in Renaissance Italy can be said to have undergone a process of dialect levelling. Merchant letters in the Italian context are characterised by their high degree of verb allomorphy, both verbal and nominal. Previous investigations have shown that this degree of allomorphy is much more present in merchant texts than in other text genres immediately preceding codification in the 1500s. This article continues this line of research, showing how a process of dialect levelling occurs in a corpus of merchant writing sent from Milan in the late 1300s and early 1400s. Specifically, it focuses on 1pl. verb endings and the presence of voicing in past participles to show that Tuscan linguistic items infiltrated and then spread into neighbouring dialectal areas, such as Gallo-Italian, that is typologically distinct from Tuscan. Since this process of levelling was occurring at the same time as literary Tuscan was spreading, sometimes mediated also by merchants, the article also discusses these issues. While focus is placed on the contribution of merchant language in Renaissance Italy, the article can be seen as a case-study as evidence of language evolution ‘from below’. Overall, it argues that historical sociolinguistics provide powerful tools which help to show the various processes identified during standardization.

Deutelio approach to fusion energy with the Polomac

Deutelio is a private initiative promoting an alternative path to fusion energy. The Tokamak research line pursued worldwide since 1970 met several difficulties, heavily jeopardising the objective of commercial energy production from fusion before 2050, as a support to the global effort towards Net Zero Emissions. As a result, new plasma magnetic confinement concepts, such as Stellarators or overlooked alternatives like the poloidal confinement are being pursued to achieve more efficiency and better performance. The Polomac is a poloidal magnetic configuration where the outboard magnetic lines are deviated aside together with the plasma, to open some accesses to the dipole coils located inside the plasma. These accesses, called magnetic tunnels, are used to support, feed and cool the dipole coil. They avoid the impact with plasma which led to abandon past poloidal experiments, despite their good stability and confinement efficiency. The poloidal confinement can achieve Deuterium-Tritium reactor conditions with a magnetic field 3 times weaker than the Tokamak, in steady state rather than pulsed. With the same high field as in the Tokamak the poloidal confinement can achieve Deuterium-Deuterium reaction, thus avoiding the development of the breeding blanket to produce the Tritium. This paper presents the Polomac system, explains the development strategy of Deutelio through a small prototype focused to tune and assess the magnetic tunnels, and describes the possibility of deuterium-deuterium reaction.
