Work Expectations, Depressive Symptoms, and Passive Suicidal Ideation Among Older Adults: Evidence From the Health and Retirement Study.

Employment and work transitions (e.g., retirement) influence mental health. However, how psychosocial contexts such as anticipation and uncertainty about work transitions, irrespective of the transitions themselves, relate to mental health is unclear. This study examined the relationships of work expectations with depressive symptoms, major depression episodes (MDE), and passive suicidal ideation over a 10-year period among the "Baby Boom" cohort of the Health and Retirement Study. Analysis was limited to 13,247 respondents aged 53-70 observed from 2008 to 2018. Past-year depressive symptoms, MDE, and passive suicidal ideation were indexed using the Composite International Diagnostic Interview-Short Form. Expectations regarding working full-time after age 62 were assessed using a probability scale (0%-100%). Mixed-effect logistic regressions with time-varying covariates were used to assess the relationship of work expectations with mental health, accounting for demographics, health status, and functioning, and stratified by baseline employment status. At baseline, higher work expectations were inversely associated with depressive symptoms. Longitudinally, higher expectations were associated with lower odds of depressive symptoms (odds ratio [OR] = 0.93, 95% CI: 0.91, 0.94). This association was more pronounced among respondents not working at baseline (ORNot working = 0.93 vs ORWorking = 0.96). Greater uncertainty (i.e., expectations near 50%) was also inversely associated with depressive symptoms. Results were similar for past-year MDE and passive suicidal ideation. Expectations (overall likelihood and uncertainty), as indicators of psychosocial context, provide insight into the processes that link work transitions with depression risk.

Phylogenetically Distant BABY BOOM Genes From Setaria italica Induce Parthenogenesis in Rice.

The combination of apomixis and hybrid production is hailed as the holy grail of agriculture for the ability of apomixis to fix heterosis of F1 hybrids in succeeding generations, thereby eliminating the need for repeated crosses to produce F1 hybrids. Apomixis, asexual reproduction through seed, achieves this feat by circumventing two processes that are fundamental to sexual reproduction (meiosis and fertilization) and replacing them with apomeiosis and parthenogenesis, resulting in seeds that are clonal to the maternal parent. Parthenogenesis, embryo development without fertilization, has been genetically engineered in rice, maize, and pearl millet using PsASGR-BABY BOOM-like (PsASGR-BBML) transgenes and in rice using the OsBABY BOOM1 (OsBBM1) cDNA sequence when expressed under the control of egg cell-specific promoters. A phylogenetic analysis revealed that BABY BOOM (BBM)/BBML genes from monocots cluster within three different clades. The BBM/BBML genes shown to induce parthenogenesis cluster within clade 1 (the ASGR-BBML clade) along with orthologs from other monocot species, such as Setaria italica. For this study, we tested the parthenogenetic potential of three BBM transgenes from S. italica, each a member of a different phylogenetic BBM clade. All transgenes were genomic constructs under the control of the AtDD45 egg cell-specific promoter. All SiBBM transgenes induced various levels of parthenogenetic embryo development, resulting in viable haploid T1 seedlings. Poor seed set and lower haploid seed production were characteristics of multiple transgenic lines. The results presented in this study illustrate that further functional characterization of BBMs in zygote/embryo development is warranted.

Modernism on the Line

The invitation to this symposium refers to "the baby boom, which "boosted the market for children's toys."" This paper explores the extent to which the toys of that era in New Zealand could be seen to have actively promoted and encouraged Modernist architecture. The particular focus will be on toy trains and model railways and how their manufacturers, both off-shore and local, produced model railway buildings that were decidedly Modern in form and quite unlike the largely nineteenth-century buildings seen by the majority of travellers on New Zealand Railways. This paper argues that 1950s New Zealand was an outpost of non-Modernism when it comes to railway buildings, both full size and toys. By tracing the history of model railways and how they engaged with Modern design it posits that the only OO scale model railway buildings that were mass produced in New Zealand were traditional in form, although made of plastic, the quintessentially modern material.

Birth order and the decline in college completion among the baby boom generation

We show that changes in birth order during the U.S. baby boom can explain a substantial share of the decline and recovery in college completion among cohorts born between 1946 and 1974. Combining birth order effects estimated using the Health and Retirement Survey and birth order data from Vital Statistics, we estimate that changes in birth order can explain about 20% of the decline in white male college completion rates among the 1946–60 cohorts, and about one third of the rebound among the 1960–74 cohorts.

Good Planning or Good Intentions

Cities across Canada are aging—fast. As the “baby boom” generation enters older adulthood, cities are facing a dramatic demographic shift. However, it is unclear whether cities in Canada are prepared to meet the needs of the growing older adult population. Through the case study of one of Canada’s demographically oldest cities, Victoria, BC, we assess the age-friendliness of local plans and policies. Specifically, we conduct a plan evaluation content analysis to assess the city’s Official Community Plan and supporting statutory plans to determine whether the city is truly planning for an age-friendly environment. We find that while the city is aware of the aging population, it fails to explicitly mention or provide targeted policies for older adults in its planning documents. We unpack the practical challenges of planning for an aging population and provide targeted recommendations for municipalities to incorporate age-friendly elements within their statutory plans.

Analysis of Online Home Training Users’ Behavioral Intention and Use Behavior Based on the UTAUT Model: Moderating Roles of Risk Perception toward the COVID-19 Infection and Generational Difference

PURPOSE This study aimed (1) to analyze the behavioral intention and use behavior among the consumers of online home training contents via YouTube by employing the unified theory of acceptance and use of technology (UTAUT); (2) to test the moderating effects of risk perception toward the coronavirus (COVID-19) infection, and 3) to test differential impacts of generational difference across millennial and baby boom generations.METHODS A total of 400 questionnaires were distributed, and 383 samples were used for the final analysis after excluding 17 incomplete responses. Data were analyzed using the SPSS 25.0 and AMOS 22.0.RESULTS It was found that (1) the performance expectancy, the effort expectancy, and the social influence had positive effects on behavioral intention; (2)the facilitating condition had negative effects on the use behavior; (3) the behavioral intention had positive impact on the use behavior. Moreover, the risk perception toward the COVID-19 infection did not have moderating impacts on the UTAUT model, whereas generational differences did.CONCLUSIONS Our results suggest that the marketing strategy that improves exercise performance, convenience, and social influencing factors may be key to home training customers' behavioral intention and use behavior. Furthermore, home training material makers should recognize that the features and infrastructure required for the two generations are distinct and develop a separate marketing strategy for each.

Recent Developments and Strategies for the Application of Agrobacterium-Mediated Transformation of Apple Malus × domestica Borkh.

Genetic transformation has become an important tool in plant genome research over the last three decades. This applies not only to model plants such as Arabidopsis thaliana but also increasingly to cultivated plants, where the establishment of transformation methods could still pose many problems. One of such plants is the apple (Malus spp.), the most important fruit of the temperate climate zone. Although the genetic transformation of apple using Agrobacterium tumefaciens has been possible since 1989, only a few research groups worldwide have successfully applied this technology, and efficiency remains poor. Nevertheless, there have been some developments, especially in recent years, which allowed for the expansion of the toolbox of breeders and breeding researchers. This review article attempts to summarize recent developments in the Agrobacterium-mediated transformation strategies of apple. In addition to the use of different tissues and media for transformation, agroinfiltration, as well as pre-transformation with a Baby boom transcription factor are notable successes that have improved transformation efficiency in apple. Further, we highlight targeted gene silencing applications. Besides the classical strategies of RNAi-based silencing by stable transformation with hairpin gene constructs, optimized protocols for virus-induced gene silencing (VIGS) and artificial micro RNAs (amiRNAs) have emerged as powerful technologies for silencing genes of interest. Success has also been achieved in establishing methods for targeted genome editing (GE). For example, it was recently possible for the first time to generate a homohistont GE line into which a biallelic mutation was specifically inserted in a target gene. In addition to these methods, which are primarily aimed at increasing transformation efficiency, improving the precision of genetic modification and reducing the time required, methods are also discussed in which genetically modified plants are used for breeding purposes. In particular, the current state of the rapid crop cycle breeding system and its applications will be presented.

Age-Unfriendly by Design

Problem, research strategy, and findings The world’s population is aging at a rapid rate, yet many local built and social environments are not well suited to support older adults. Australia exemplifies the demographic–environmental disconnect because it is one of the world’s most suburban nations and has one of the proportionally largest baby boom generations. In this research we examined the relationship between built and social environments with respect to older adult vulnerability in Greater Melbourne (Australia). We found that neighborhoods with lower levels of built environment support also had lower levels of social infrastructure. The spatial imbalance across the region was most pronounced when considering the spatial distribution of older adults aged 85 years and older. Our analysis of policymaker interviews revealed a marked disconnect between the scale and scope of the challenges of suburban aging and the state and local government response. Limitations of the study included the operationalization of built environment and social infrastructure variables. Takeaway for practice Age-friendly planning and design cannot be limited to the “easier stuff” such as communication and information, social participation, and respect and inclusion. Suburban built environments require more effort and investment in transportation, housing, and outdoor spaces and buildings to support the physical and mental wellbeing of older adults aging in place. Walkable suburban neighborhoods with high levels of accessible social infrastructure will help build community connections and encourage older adult physical activity and social engagement.

BABY BOOM regulates early embryo and endosperm development.

The BABY BOOM (BBM) AINTEGUMENTA-LIKE (AIL) AP2/ERF domain transcription factor is a major regulator of plant cell totipotency, as it induces asexual embryo formation when ectopically expressed. Surprisingly, only limited information is available on the role of BBM during zygotic embryogenesis. Here we reexamined BBM expression and function in the model plant Arabidopsis thaliana (Arabidopsis) using reporter analysis and newly developed CRISPR mutants. BBM was expressed in the embryo from the zygote stage and also in the maternal (nucellus) and filial (endosperm) seed tissues. Analysis of CRISPR mutant alleles for BBM (bbm-cr) and the redundantly acting AIL gene PLETHORA2 (PLT2) (plt2-cr) uncovered individual roles for these genes in the timing of embryo progression. We also identified redundant roles for BBM and PLT2 in endosperm proliferation and cellularization and the maintenance of zygotic embryo development. Finally, we show that ectopic BBM expression in the egg cell of Arabidopsis and the dicot crops Brassica napus and Solanum lycopersicon is sufficient to bypass the fertilization requirement for embryo development. Together these results highlight roles for BBM and PLT2 in seed development and demonstrate the utility of BBM genes for engineering asexual embryo development in dicot species.

An Empirical Evidence of the Effects of Social Relations, Social Care, and Social Activities on Elderly Well-being in Malaysia

As the world is undergoing a demographic revolution since 1950, life expectancy has increased by more than two decades, and the population has grown significantly. According to the World Health Organization (WHO), the population of individuals who are over the age of 60 is increasing faster than any other age groups in almost every country (Cromley, Maureen, Zachary, Pruchno, 2015). Malaysia had 2.2 million elderly people in 2019, and the figure is expected to rise to 3.6 million by 2030 (Ismail, 2017). According to statistics, the world, including Malaysia, will face the phenomenon of ageing which occurs when 7 percent of the population is 65 or older (WHO, 2017). Year after year, the population of the elderly grows at a rapid rate, leading towards the phenomenon of ageing (Amarya & Singh, 2018; Rahim, 2018; Hamid, 2018). This is due to a combination of factors such as increased longevity, lower fertility, and the ageing of the "baby boom" generation (Kemperman, Berg, Weijs, & Kevin, 2019). This increased longevity and quality of life in older adults presents a challenge to physical and mental health professionals working to help the growing elderly population live not only longer and healthier lives, but also better and happier lives (Kemperman et al., 2019).

Not alone: Family experiences across the life course of single, baby boom sexual‐minority women

AbstractObjectiveAs older LGBTQ+ people are less likely to be married than non‐LGBTQ+ peers and historically may have been disconnected from their families of origin, the aim of this study was to understand the family life of single sexual minority women of the baby boom cohort throughout their lives.BackgroundSinglehood, in general, has meant not being in a heterosexual—or legally recognized—relationship; thus women in same‐sex relationships historically were considered single. As women gained more rights, single and lesbian, bisexual, and queer women have gained opportunities to live outside heterosexual marriage, financially and with regard to social acceptability. Women of the baby boom cohort, born between 1946 and 1964, came of age during this societal shift.MethodFramed by feminist and life course perspectives, this study was qualitative, used semistructured interviews, and was guided by a constructivist paradigm and thematic analysis to understand how 13 older sexual minority women perceived family.FindingsThe women noted their connection to family of origin, then romantic relationships and partners, and currently, identify family as including biological, adopted, and chosen kin.ConclusionSingle LBQ women of the baby boom cohort have relational resources through friends as family, biological kin, legal kin, and creating community.ImplicationsMore expansive understandings of family, including chosen family and invisible kin, comprise the support networks of older women who have lived outside heteronormativity.

CRISPR/Cas9-mediated tetra-allelic mutation of the 'Green Revolution' SEMIDWARF-1 (SD-1) gene confers lodging resistance in tef (Eragrostis tef).

SummaryTef is a staple food and a valuable cash crop for millions of people in Ethiopia. Lodging is a major limitation to tef production, and for decades, the development of lodging resistant varieties proved difficult with conventional breeding approaches. We used CRISPR/Cas9 to introduce knockout mutations in the tef orthologue of the rice SEMIDWARF‐1 (SD‐1) gene to confer semidwarfism and ultimately lodging resistance. High frequency recovery of transgenic and SD‐1 edited tef lines was achieved in two tef cultivars by Agrobacterium‐mediated delivery into young leaf explants of gene editing reagents along with transformation and regeneration enhancing morphogenic genes, BABY BOOM (BBM) and WUSCHEL2 (WUS2). All of the 23 lines analyzed by next‐generation sequencing had at least two or more alleles of SD‐1 mutated. Of these, 83% had tetra‐allelic frameshift mutations in the SD‐1 gene in primary tef regenerants, which were inherited in subsequent generations. Phenotypic data generated on T1 and T2 generations revealed that the sd‐1 lines have reduced culm and internode lengths with no reduction in either panicle or peduncle lengths. These characteristics are comparable with rice sd‐1 plants. Measurements of lodging, in greenhouse‐grown plants, showed that sd‐1 lines have significantly higher resistance to lodging at the heading stage compared with the controls. This is the first demonstration of the feasibility of high frequency genetic transformation and CRISPR/Cas9‐mediated genome editing in this highly valuable but neglected crop. The findings reported here highlight the potential of genome editing for the improvement of lodging resistance and other important traits in tef.

Is Two Still Best? Change in Parity-Specific Fertility Across Education in Low-Fertility Countries

The dominance of two-child families is considered an intrinsic characteristic of low fertility societies. Their share was continuously increasing among baby boom cohorts but the rise ceased afterwards. While parity- and education-specific fertility trends during the expansion of the two-child families have been studied, corresponding analyses of developments in the post-expansion birth cohorts are scarce. This study investigates the parity-specific fertility trends that ended the expansion of two-child families across educational groups. We use data on completed fertility of female cohorts born between 1936 and 1970 in 16 low-fertility countries. Besides examining trends in education- and parity-specific fertility, we provide evidence on increasing variation in family size and on the contribution of parity-specific fertility to the share of two child families among women with low, medium and high education. Our results show that the expansion of two-child families stopped as the variation in family size increased: transition rates to first and/or second birth declined whereas those to third birth increased. This polarisation process was strongest among women with low education. Apparently, as the number of women progressing to second birth declined, they became more selected and family-oriented, and thus more likely to progress to further births. The fact that the strongest polarisation of fertility was observed among the low educated reflects the group’s increasing selectivity. We demonstrate that rising polarisation of family size is a common development to most high-income low-fertility populations, especially among the low educated, regardless of substantial cross-country differences in fertility levels as well as in institutional, economic and cultural settings.

베이비붐 세대의 죽음불안이 우울과 자아통합감에 미치는 영향

The purpose of this research is to investigate the mediating effect of active aging in the relationship between depression and ego-integrity of death anxiety on baby boom generation. For this purpose, the data were collected using death anxiety, active aging, depression, and ego-integrity measures from 600 adult men and women living in the baby boom generation (1955-1963) nationwide. The results indicated that first, there was a significant correlation between the main variables of this study. Second, when death anxiety effect on depression, active aging has a significant partial mediating effect. Third, when death anxiety affects on ego-integrity, active aging has a significant partial mediating effect. Through this study, psychological intervention programs and policy support measures to reduce depression of baby boomers and increase ego-integrity were examined. Lastly, this study ends with discussions of implications, limitations, and suggestion.

Mass Weddings, Baby Boom and Full Employment?

Abstract In 1933, the German government introduced the marriage loan for newlyweds, a policy aimed at increasing marriages and births as well as male employment, which entailed a work ban for the wife and sizeable credit deductions for children. This paper illustrates that the policy was rather ineffective based on a critical evaluation of the existing literature on the topic, how the policy was implemented in practice, as well as a correlation and interrupted time series analysis and consideration of the historical context of the period between 1925 and 1939. This result starkly contrasts to the substantial changes expected at the time of the introduction. In theory, only a small fraction of newlyweds was eligible for the loan. In practice, the development of marriages postintroduction significantly differed from the period prior to the policy, but causation is unclear. While births increased, this can be attributed to a combination of policies and the improved economic environment compared to the crisis years. The sharp decrease in unemployment probably resulted from the introduction of several targeted policies and embellishment of unemployment statistics.

¿Ha variado la sexualidad en el embarazo? Generación baby boom versus generación millennial

Sexuality is a complex and multidimensional phenomenon that constitutes a fundamental component in human relationships. Pregnancy is a crucial period in women's life and the physiological changes that happen in this period affect their sexuality. ObjectiveKnowing how pregnancy impacts on sexual behaviors in millenial generation compared to baby boom generation. Material and methodsDescriptive and cross-sectional study, by means of a self-completed, population-based survey, to a sample of pregnant women in the third trimester of gestation who attended Primary Care. A descriptive study of the frequency distribution of all the variables was carried out. ResultsIn baby boom generation and millennial generation, it is observed that during pregnancy couple's attraction decreases slightly. According to variables desire and frequency of intercourse, results obtained show that as the pregnancy progresses there is a marked decrease in desire and intercourse frequency. Women state that they do not have enough information about sexuality in their current state, despite years having passed. ConclusionsDuring last 35 years, sexual behaviors have not changed in pregnant women. In both generations, changes in desire and intercourse domains were particularly significant, being in third trimester of pregnancy when frequency of intercourse decline. Pregnant women continue to hold erroneous beliefs about sexuality and request more sexual education.

Better cognitive function in younger generations - Insights from two cohort studies of middle-aged to older adults in Wisconsin

BackgroundUnderstanding generational trends in dementia and cognitive decline is essential to quantify future healthcare needs and may help identify interventions and preventions. We aimed to determine whether individuals from more recent generations showed better neurocognitive function. MethodsThis cross-sectional study combined data from 4439 participants (mean age 64 years (SD = 13); 57% were women) from the Epidemiology of Hearing Loss Study and Beaver Dam Offspring Study. We assessed participants' birth cohort (1901–1924, Greatest Generation; 1925–1945, Silent Generation; 1946–1964, Baby Boom Generation; 1965–1984, Generation X) and neurocognition (Trail-Making Tests A and B, Digit Symbol Substitution Test, Auditory Verbal Learning Test, Verbal Fluency Test). Multivariable linear regression models were utilized. ResultsAdjusted for age, sex, education, and known risk factors for cognitive decline, more recent generations showed better processing speed, executive function, attention, and verbal fluency than the Greatest Generation. Largest benefits were found in the Baby Boom Generation. Compared with the Greatest Generation, individuals from the Baby Boom Generation performed better on Trail-Making Tests A (−0.21 ln(time in s); 95% confidence interval (CI) −0.29, −0.13) and B (−0.31 ln(time in s); 95% CI −0.40, −0.22), Digit Symbol Substitution Test (6.07 numbers correct; 95% CI 3.61, 8.52) and Verbal Fluency Test (8.75 numbers correct; 95% CI 5.07, 12.42 in women; 5.28 numbers correct; 95% CI 0.79, 9.78 in men), with effect sizes similar to effects of 11–15 years of less aging. ConclusionsThis indicates that some benefits of younger generations might be related to yet unknown and potentially modifiable environmental, health-related or lifestyle factors and motivates research of such underlying factors to promote healthy cognitive aging.

Optimized Transformation and Gene Editing of the B104 Public Maize Inbred by Improved Tissue Culture and Use of Morphogenic Regulators.

Plant transformation is a bottleneck for the application of gene editing in plants. In Zea mays (maize), a breakthrough was made using co-transformation of the morphogenic transcription factors BABY BOOM (BBM) and WUSCHEL (WUS) to induce somatic embryogenesis. Together with adapted tissue culture media, this was shown to increase transformation efficiency significantly. However, use of the method has not been reported widely, despite a clear need for increased transformation capacity in academic settings. Here, we explore use of the method for the public maize inbred B104 that is widely used for transformation by the research community. We find that only modifying tissue culture media already boosts transformation efficiency significantly and can reduce the time in tissue culture by 1 month. On average, production of independent transgenic plants per starting embryo increased from 1 to 4% using BIALAPHOS RESISTANCE (BAR) as a selection marker. In addition, we reconstructed the BBM-WUS morphogenic gene cassette and evaluated its functionality in B104. Expression of the morphogenic genes under tissue- and development stage-specific promoters led to direct somatic embryo formation on the scutellum of zygotic embryos. However, eight out of ten resulting transgenic plants showed pleiotropic developmental defects and were not fertile. This undesirable phenotype was positively correlated with the copy number of the morphogenic gene cassette. Use of constructs in which morphogenic genes are flanked by a developmentally controlled Cre/LoxP recombination system led to reduced T-DNA copy number and fertile T0 plants, while increasing transformation efficiency from 1 to 5% using HIGHLY-RESISTANT ACETOLACTATE SYNTHASE as a selection marker. Addition of a CRISPR/Cas9 module confirmed functionality for gene editing applications, as exemplified by editing the gene VIRESCENT YELLOW-LIKE (VYL) that can act as a visual marker for gene editing in maize. The constructs, methods, and insights produced in this work will be valuable to translate the use of BBM-WUS and other emerging morphogenic regulators (MRs) to other genotypes and crops.

Racial/ethnic disparities in hepatocellular carcinoma incidence and mortality rates in the United States, 1992-2018.

HCC is characterized by racial/ethnic disparities in rates. Recent USA reports suggest that incidence has begun to decline, but it is not clear whether the declines have occurred among all groups, nor whether mortality has declined. Thus, the current study examined USA incidence and mortality between 1992 and 2018. HCC incidence and incidence-based mortality data from the Surveillance, Epidemiology, and End Results program were used to calculate age-standardized rates by race/ethnicity, sex, and age. Trends were analyzed using joinpoint regression to estimate annual percent change (APC). Age-period-cohort models assessed the effects on trends of age, calendar period, and birth cohort. Overall, HCC incidence significantly declined between 2015 and 2018 (APC, -5.6%). Whereas most groups experienced incidence declines, the trends were most evident among Asians/Pacific Islanders, women, and persons <50 years old. Exceptions were the rates among non-Hispanic Black persons, which did not significantly decline (APC, -0.7), and among American Indians/Alaska Natives, which significantly increased (APC, +4.3%). Age-period-cohort modeling found that birth cohort had a greater effect on rates than calendar period. Among the baby boom cohorts, the 1950-1954 cohort had the highest rates. Similar to the overall incidence decline, HCC mortality rates declined between 2013 and 2018 (APC, -2.2%). HCC incidence and mortality rates began to decline for most groups in 2015, but persistent differences in rates continued to exist. Rates among non-Hispanic Black persons did not decline significantly, and rates among American Indians/Alaska Natives significantly increased, suggesting that greater effort is needed to reduce the HCC burden among these vulnerable groups.
