The growing number of senior experts leaving the workforce (especially in more developed economies, such as in Europe), combined with the ubiquitous access to artificial intelligence (AI), is triggering organizations to review their knowledge transfer programs, motivated by both financial and management perspectives. Our study aims to contribute to the field by analyzing options to integrate intergenerational tacit knowledge transfer (InterGenTacitKT) with AI-driven approaches, offering a novel perspective on sustainable Knowledge and Human Resource Management in organizations. We will do this by building on previous research and by extracting findings from 36 in-depth semi-structured interviews that provided success factors for junior/senior tandems (JuSeTs) as one notable format of tacit knowledge transfer. We also refer to the literature, in a grounded theory iterative process, analyzing current findings on the use of AI in tacit knowledge transfer and triangulating and critically synthesizing these sources of data. We suggest that adding AI into a tandem situation can facilitate collaboration and thus aid in knowledge transfer and trust-building. We posit that AI can offer strong complementary services for InterGenTacitKT by fostering the identified success factors for JuSeTs (clarity of roles, complementary skill sets, matching personalities, and trust), thus offering organizations a powerful means to enhance the effectiveness and sustainability of InterGenTacitKT that also strengthens employee productivity, satisfaction, and loyalty and overall organizational competitiveness.

The decline in colorectal cancer (CRC) due to screening success in the U.S. is inconsistent across populations and age groups. CHamorus (Chamorros) and Filipinos constitute minorities in the U.S. but comprise over 70% of the population in Guam where steep increases in CRC incidence occur before the age of 50, and only 53.9% of persons have met national screening standards. This preliminary study explored knowledge, cultural beliefs, and age-specific recommendations associated with CRC and screening. Five focus groups segregated by age and gender were conducted with persons aged 40 and above. Data were collected on knowledge, attitudes, beliefs, and screening education recommendations. Focus group participants (n = 25) were predominantly CHamoru (60%), Filipino (32%), and female (56%). The mean age was 55. Participants preferred interventions that integrated storytelling from CRC survivors with emphasis on family education rather than limiting to screening-age adults. Multicoders performed an iterative collaborative analysis for the main themes: knowledge of CRC/screening primarily derives from family experiences; increased outreach is needed for men; use of personal narratives; and screening is motivated by family values and intergenerational consciousness. Findings can inform future studies on age- and culturally-tailored early detection strategies to improve CRC screening participation in Pacific populations. Full article

This study explores the “nonprofitization” of youth climate organizing from the perspective of six youth activists who participated in designing a pilot environmental activism program for a large science museum located in Northern California. Through case study methodology, the authors explore how adultism and institutional control stifled youth activism and the ultimate success of their initiatives. Our analysis highlights the institutional practices, intergenerational value gaps, and inadequate understanding of social movement principles from the partner site that reified colonial hierarchies of knowledge and prevented genuine support and collaboration with youth in climate activism. Factors such as profit motives, a desire for control, generational gaps, and a failure to see youth as equals contribute to this problem. We conclude by proposing alternative institutional practices with youth that center on intergenerational power-sharing to counter the trend of nonprofit organizations greenwashing youth social movements.

In the sustainable evolution of the entrepreneurial ecosystem, the efficiency of early-stage capital allocation directly affects the intergenerational transmission capacity of innovation resources. The financing barriers caused by information asymmetry urgently require institutional solutions. This study, based on tracking data from 19,463 startups in China’s information technology sector (2016–2019), analyzes how government-certified incubators (GCIs) optimize the sustainability of the entrepreneurial ecosystem through signaling mechanisms. The empirical results show that collaboration with a GCI can significantly increase the likelihood of IT startups securing venture capital by approximately 25%. This effect is not only due to the strict screening and resource support provided by GCIs, but also due to their role in amplifying internal signals from startups, such as the experience of founders and intellectual property. Notably, in the IT sector, the impact of GCIs is more significant for startups traditionally disadvantaged, particularly those led by female founders. Our research demonstrates that GCIs drive the sustainable development of the entrepreneurial ecosystem through three signaling mechanisms: (1) institutional certification screening, which optimizes the intergenerational allocation efficiency of ecosystem resources; (2) the signaling validation–amplification mechanism, which enhances the value of intellectual property and founder experience, alleviating investors’ challenges in quantifying startup potential; (3) inclusive signal rebalancing, where GCI certification significantly improves the funding success rate of female founders, breaking traditional market biases in screening disadvantaged groups and supporting the inclusive and sustainable development of the entrepreneurial ecosystem. These findings provide a new pathway for emerging economies to optimize the resilience of their entrepreneurial ecosystems through policy tools: for governments, GCIs achieve sustainable development goals at low institutional cost; for investors, the signal integration mechanism reduces investment information friction; and for entrepreneurs, certification endorsements accelerate market validation of sustainable business models.

Nowadays, women’s contribution to society through their social and human involvement at the household level in terms of education, care, and nutrition, as well as their added value to economic functioning, is increasingly recognized. However, most of the related research highlights the relative contributions of women and men. This paper proposes to analyze the link between women’s contribution to social, economic, and financial activities and the rural livelihood of the whole household farm. Based on a household survey that included a respondent section for women from over 285 families in the least rurally developed regions of Morocco, descriptive statistics and systemic analysis successively based on multiple factorial and clustering analyses were used to analyze the links between household adaptative capacity and women’s material and immaterial contributions. The results revealed that women play a crucial role in intergenerational knowledge transfer, which constitutes a critical factor in household capacities and reproduction, especially in the least endowed households. However, the women’s farm or off-farm activities did not guarantee their autonomy. So, the contribution of women to household farm livelihood through their know-how opens alternative pathways to reconsider their contribution to the overall goal of livelihood improvement.

Black women come from a lineage of survivors who have faced threats to their economic livelihoods since the emancipation of slavery. These threats are deeply rooted in the systemic expectation of free labor, which dates to the illegal enslavement of Black individuals beginning in 1619. A new emerging concept of complex economic intergenerational trauma (CEIT), grounded in Black feminist theory, examines the historical and contemporary economic exploitation of Black women at the intersection of gendered anti-Black racism. CEIT highlights ancestral capital—an essential form of wealth and survival—that has enabled Black women to succeed in a society built through their marginalization. Findings from an exploratory phenomenological study of thirteen Black women’s experiences with wealth accumulation reveal that Black women have thrived beyond the confines of the U.S. economy, despite its design to exploit their labor without providing them benefits. Ancestral capital, rooted in knowledge, values, cultural resilience, and community support, has been key to their survival and success. Today, Black women continue to face significant barriers to true economic security due to ongoing gendered anti-Black racism. However, they survive and adapt. A thematic analysis from the study shows that Black women approach economic security and wealth differently than others, placing a strong emphasis on community, collective organizing, and mutual aid. These approaches stem from a lack of access to traditional avenues of wealth accumulation available to others. Despite these ongoing challenges, Black women persist, drawing on both their inherited trauma and their unique forms of capital to navigate the economic system. This paper underscores the uniqueness of Black women by uplifting their resilience and survival, offering a testament to their ability to thrive beyond traditional financial means and continue their legacy of strength.

Crossbreeding is a traditional breeding technique and has been performed successfully in many fish species. However, distant hybridization between different genera is hard to be successful because of reproductive isolation. In this study, diploid hybrids (PL) were successfully derived from the hybridization of Ussuri catfish (Pseudobagrus ussuriensis, PU, ♀, 2n = 52) and longsnout catfish (Leiocassis longirostris, LL, ♂, 2n = 52). And the morphological data, external frame parameters, chromosomal karyotypes, DNA content measurement, mitochondrial DNA control region, and species-specific marker identification were applied to investigate the traits and genetic characterization of the PL hybrid offspring and their parents. Both quantifiable traits and shape frame parameters of the PL hybrid offspring were revealed to be intermediate between those of their parents; however, cluster analysis showed that their external morphology was more in favor of the maternal PU. The growth comparisons showed that the hybrids had significant growth advantages over maternal PU. Based on karyotype patterns, DNA contents and mitochondrial DNA, the hybrid origin and maternal inheritance of hybrid offspring were further confirmed. According to the sequence variations identified from the genome sequences of the two catfish species, one species-specific marker was developed to distinguish the PL hybrid offspring and their parents. Therefore, this study provides a successful case for intergeneric hybridization and hybrid superiority, and the PL hybrid shows promise for commercial application, pending further studies into its husbandry, health, and welfare with larger populations of fish.

Introduction: The use of alcohol, tobacco, and other drugs (ATOD) is a leading cause of preventable morbidity and mortality among adolescents. While traditional interventions have targeted specific health-risk behaviors (e.g., substance use, initiation of sexual intercourse, truancy, etc.), the evidence suggests that using a positive youth development (PYD) framework may have positive impacts across a number of domains. Friday Night Live Mentoring (FNLM) is a PYD-based, cross-age peer mentoring program that engages teams of older high school-aged youth to mentor teams of middle school-aged youth in a structured, ongoing, one-on-one relationship. While studies have demonstrated significant but small effect sizes of intergenerational youth mentoring programs in which an adult mentor is paired with the youth mentee, research on cross-age mentoring programs is limited. The purpose of the current study is to evaluate FNLM on its ability to improve participants’ knowledge, attitudes, skills, opportunities to develop caring relationships, school engagement, and academic performance. Methods: A retrospective, pre–post survey was administered online to FNLM participants across 13 California counties. Participants rated their knowledge and attitudes about ATOD, skills, relationships with peers and adults, and academic indicators. Open-ended questions gathered information about participants’ experiences in FNLM. Non-parametric related-samples Wilcoxon signed rank tests (an alternative to paired t-test) were used to compare pre–post differences. Participants were also asked two open-ended questions: “What are the best parts of FNLM?” and “What, if anything, would you change?”. The responses to each question were reviewed, coded, and analyzed according to key themes. Results: A total of 512 participants completed the survey (287 mentors and 225 protégés). There were small but statistically significant improvements across all items for both mentors and protégés. Qualitative analyses showed that most mentors and protégés especially enjoyed getting to know and spend time with one another. Several mentors added that it was rewarding to be a positive influence on or to make a positive difference in the protégé’s life. Many youth stated that the relationships formed, especially with their partner, and the activities were the best part of FNLM. The overwhelming majority would not change anything about the program. Those who provided recommendations for program improvement suggested more activities or more hands-on and engaging activities and more or longer meetings. Conclusion: FNLM actively engages youth and provides them with support and opportunities that promote knowledge, skill development, positive relationships, academic engagement, and success and raise awareness of the harms that the use of alcohol, tobacco, and other drugs (ATOD) can cause. While ATOD use was low prior to program participation, it was significantly lower after participating in the program. Full article

The aim of the work was to achieve the Italian validation of the Succession, Identity, and Consumption Scale of Prescriptive Ageism (SIC) developed by North and Fiske. SIC is a measure of prescriptive ageism, which incorporates intergenerational tensions over practical and symbolic resources. To evaluate the psychometric properties of the Italian version of the scale, two studies were conducted. Study 1 included 931 Italian participants (mean age: 30.94; range: 18–67 years; 50.5% female) and was conducted to test the scale’s structure and construct validity. Study 2 comprised 1015 Italian participants (mean age: 30.73 years; age range: 18–67; 53.5% female) and investigated the scale’s structure, construct validity, and invariance by gender and age. Confirmatory factorial analyses confirmed the three-factor solution to be invariant across sex and age groups. The scale also demonstrated high internal reliability. SIC scores correlated positively with traditional measures for detecting prejudice and stereotypes towards older people. The results of the present work show that the SIC scale of Prescriptive Ageism is a valid tool for measuring prescriptive beliefs about older adults that are the basis of intergenerational tensions.

In alignment with European policies regarding intergenerational sports, this study seeks to integrate existing evidence- (i.e., umbrella review) and eminence- (i.e., international validated educational courses for coaches) based knowledge on judo training across the lifespan. For evidence knowledge, searches of the Google Scholar, ISI-WoS, PubMed, and Scopus databases (PROSPERO ID: CRD42024535420) for studies focused on training youth and older judo practitioners, with no time restriction up to April 2024, were conducted. This resulted in 16 systematic reviews meeting the inclusion criteria, with an “excellent” (n = 6), “good” (n = 7), and “fair” (n = 3) quality according to the NIH tool. With a large sample size (n = 372,655), the reviews focused on wellbeing (n = 9; bone status, injuries, and psychophysical effects) and performance (n = 7; athlete success, combat time, rapid weight loss, and the Special Judo Fitness Test), examining athletic levels (novices to Olympics), sex, and age (children to older adults). For eminence knowledge, the International Judo Federation Academy courses encompassed the “Undergraduate Certificate as Judo Instructor” (UCJI), which provides a comprehensive structure for teaching judo, including techniques, moral code, roles, responsibilities, refereeing, safety, and age-specific belt examination requirements and progression, and the “Educating Judo Coaches for Older Practitioners” (EdJCO) curricula, which provide theoretical and applied modules (e.g., ageing, health, and organisation) to train older judo practitioners. The findings were summarised in a framework, highlighting the most relevant aspects of intergenerational judo programmes (i.e., aims, key characteristics, coaches’ roles, barriers, and facilitators). To develop a comprehensive educational intergenerational judo methodology, future research should examine coaches’ and practitioners’ opinions on intergenerational judo activities carried out in different national contexts.

The workforce is aging with the population aging. How to effectively manage and motivate older workers is significant for elderly human resources development and the sustainable development of enterprises in organizations. Age stereotypes of older workers refer to people’s beliefs and expectations about a specific group of 45–65-year-olds in the workplace. This paper examines the effect of age stereotypes of older workers on job performance and intergenerational knowledge transfer intention. This study carried out two research designs, a questionnaire survey and an experimental study, to explore the effects of positive and negative age stereotypes of older workers on job performance and intergenerational knowledge transfer intention within an organizational context and underlying mediating mechanisms. The results showed that positive stereotypes of older workers significantly positively affected job performance and intergenerational knowledge transfer intention. In comparison, negative stereotypes of older workers significantly negatively affected job performance and intergenerational knowledge transfer intention, and self-perception of aging substantially mediates the effects. This study broadens the research field on the impact of positive and negative age stereotypes on older workers in organizational contexts. This study guides organizations in reducing age discrimination, creating an inclusive workplace environment, and achieving the successful aging of older workers. Full article

Embryo rescue is a vital technique in cucurbit breeding and propagation, addressing challenges such as embryo abortion, poor seed viability, and incompatibility barriers. This method involves the excision of immature embryos from seeds followed by their in vitro culture on a nutrient medium, providing an environment conducive to their growth and development. In cucurbits, embryo rescue has been extensively utilized to overcome barriers to hybridization, enabling the production of interspecific and intergeneric hybrids with desired traits. Various factors, including genotype, developmental stage of embryos, and culture conditions, influence the success of embryo rescue in cucurbits. Optimal nutrient formulations, growth regulators, and culture techniques are critical for promoting embryo germination, shoot elongation, and subsequent plantlet establishment. Additionally, embryo rescue facilitates the recovery of valuable genetic material from wild and exotic cucurbit species, expanding genetic diversity and developing novel cultivars with improved traits such as disease resistance, yield, and quality. This review highlights the principles, applications, and advancements in embryo rescue technology in cucurbits, emphasizing its significance in cucurbit breeding programs and crop improvement efforts.

The climate crisis poses a major threat for sustainability, with the young and future generations likely to be among the most affected groups in the climate crisis. Older generations will be less affected but have a greater impact both in terms of contribution and mitigation. We investigated potential intergenerational drivers of older Germans’ climate protection intentions and behavior in two pre-registered studies (N₁ = 411, 55- to 75-year olds; N₂ = 309, 55- to 86-year olds). On a correlational level, both studies revealed that contact between generations (particularly high-quality contact) indirectly explained the participants’ climate protection intentions/behavior. This effect was mediated by affinity with younger people (Study 1) and its subfacets of perspective taking and empathic concern (but not the subfacet of perceived oneness; Study 2). Study 1 further provided evidence that legacy motivation, i.e., the desire to leave behind a positive legacy, was positively related to participants’ climate protection intentions and behavior. Study 2’s attempt at testing the causal role of the subfacets of affinity was not successful, as the experimental manipulation of perspective taking toward younger people failed. However, the two studies provide correlational evidence that the closer older people feel to younger people and the future consequences of their behaviors, the more willing they are to protect the climate.

Embryo rescue (ER) techniques are among the oldest and most successful in vitro tissue culture protocols used with plant species. ER refers to a series of methods that promote the development of an immature or lethal embryo into a viable plant. Intraspecific, interspecific, or intergeneric crosses allow the introgression of important alleles of agricultural interest from wild species, such as resistance or tolerance to abiotic and biotic stresses or morphological traits in crops. However, pre-zygotic and post-zygotic reproductive barriers often present challenges in achieving successful hybridization. Pre-zygotic barriers manifest as incompatibility reactions that hinder pollen germination, pollen tube growth, or penetration into the ovule occurring in various tissues, such as the stigma, style, or ovary. To overcome these barriers, several strategies are employed, including cut-style or graft-on-style techniques, the utilization of mixed pollen from distinct species, placenta pollination, and in vitro ovule pollination. On the other hand, post-zygotic barriers act at different tissues and stages ranging from early embryo development to the subsequent growth and reproduction of the offspring. Many crosses among different genera result in embryo abortion due to the failure of endosperm development. In such cases, ER techniques are needed to rescue these hybrids. ER holds great promise for not only facilitating successful crosses but also for obtaining haploids, doubled haploids, and manipulating the ploidy levels for chromosome engineering by monosomic and disomic addition as well substitution lines. Furthermore, ER can be used to shorten the reproductive cycle and for the propagation of rare plants. Additionally, it has been repeatedly used to study the stages of embryonic development, especially in embryo-lethal mutants. The most widely used ER procedure is the culture of immature embryos taken and placed directly on culture media. In certain cases, the in vitro culture of ovule, ovaries or placentas enables the successful development of young embryos from the zygote stage to maturity. Full article
