Beam-Hopping (BH) and precoding are two trending technologies for the satellite community. While BH enables flexibility to adapt the offered capacity to the heterogeneous demand, precoding aims at boosting the spectral efficiency. In this paper, we consider a high throughput satellite (HTS) system that employs BH in conjunction with precoding. In particular, we propose the concept of Cluster-Hopping (CH) that seamlessly combines the BH and precoding paradigms and utilizes their individual competencies. The cluster is defined as a set of adjacent beams that are simultaneously illuminated. In addition, we propose an efficient time-space illumination pattern design, where we determine the set of clusters that can be illuminated simultaneously at each hopping event along with the illumination duration. We model the CH time-space illumination pattern design as an integer programming problem which can be efficiently solved. Supporting results based on numerical simulations are provided which validate the effectiveness of the proposed CH concept and time-space illumination pattern design. [less ▲]

Despite considerable stability of the Big Five personality traits, there is evidence for personality plasticity and change across the lifespan. In younger years, the investment in social roles, such as entering worklife or starting a family has been shown to drive personality change. With regard to personality in later life, the investigation of social roles has so far been neglected. A questionnaire was developed to assess a large number of social roles that can be assumed in the second half of life. N = 306 participants aged 50 to 86 years reported on their social roles and rated their personality traits. Results show that assuming and investing in certain social roles (e.g. friend, retiree, volunteer) mediated the effects of age on the Big Five, especially for the oldest participants and in the domains openness and extraversion. The findings support the importance of social roles for personality also in later life. [less ▲]

Big Five personality traits are assumed to be linked with attitudes toward own aging (ATOA). Both constructs have central importance for the aging process, it is thus important to comprehensively address their mutual connection over time. We used data from the ILSE study, a longitudinal study with four measurement occasions, spanning 20 years and including two participant cohorts (n = 501; born 1950-52 and n = 500; born 1930-32). Dual latent change score models showed that personality was longitudinally related to change in ATOA: Lower Neuroticism, higher Conscientiousness, and higher Openness predicted more positive attitudes; the effect for Extraversion varied by time. Furthermore, the role of personality seems to be confined to certain sensitive periods in midlife and early old age. ATOA had only marginal longitudinal impact on personality. Our results shed light on the developmental co-dynamics of personality and subjective perceptions of aging across the second half of life. [less ▲]

Using questionnaire data from the MIDUS study (N=6.325) we examined the extent to which people in their late 20s, 40s, and 60s think that positive stereotypic “old” and “young” characteristics describe themselves, their age peers, and other age groups. A constellation of “old” characteristics (e.g., wise, caring, calm) was seen as more descriptive of older adults, while a constellation of “young” characteristics (e.g., healthy, energetic) was seen as more descriptive of younger adults. Self-evaluations were highly positive and largely consistent across age groups. Compared to their age peers, younger adults saw themselves as having as many positive “young” characteristics but more positive “old” characteristics whereas older adults saw themselves as having more positive “young” characteristics but fewer positive “old” characteristics. The results support the stability of the aging self despite the existence of age stereotypes and the role of negative age stereotypes as a frame of reference for making self-evaluations. [less ▲]

Over the past 20 years, research on views on aging has substantiated their importance for successful development and sustained quality of life over the full length of the life span. However, a deep understanding of the origins of views on aging and the underlying processes of their lifespan development and manifestation is lacking. Since 2017, the scientific network “Images of Aging” funded by the German Research Foundation (http://www.health.uni-konstanz.de/images-of-aging) assembles national and international renowned experts in the field. The network engages in empirical clarifications on both the distinctness and validity of the construct (contribution of Klusmann et al.) as well as in critically reviewing terminology and measures of views on aging (contribution of Notthoff et al.). The network aims to help clarifying the dynamic interplay of determinants and outcomes in the context of health (contribution of Wolff et al.) as well as disentangling intra- and intergenerational stereotypic perceptions (contribution of Kornadt et al.). Both of these are understudied issues with highly practical implications for two of the largest demographic challenges: shaping the coexistence of generations as well as providing adequate health care supply. Integrating both pertinent theoretical approaches and empirical findings the network regards views on aging under a lifespan perspective. Recently, it suggested three core principles of views on aging regarding lifelong bio-psycho-social development, their multidimensional nature, and their impact across life. These considerations provide a background for an integrative discussion of the symposium’s contributions. [less ▲]

Using data from the German Ageing Survey (adults aged 40‒85), this study tested the convergent and discriminant validity of subjective aging measures by comparing three different measures of subjective aging with one another and relating them to established measures of general self-beliefs (optimism, self-efficacy, subjective health) and subjective well-being (depression, affect). Correlations between subjective aging measures ranged from ‒.61 (amongst general self-perceptions of aging measures) to ‒.09, with subjective age being least related to the other measures. The highest overlap was observed between optimism and global self-perceptions of aging (.69) and it was for these global self-perceptions that the highest amount of variance could be explained by correlates in a regression analysis (R-square=.55). In contrast, only 10% of variance could be explained for subjective age. Our results underline the merit of taking the multidimensional nature of subjective aging into account since global measures appear less distinct from general personality traits. [less ▲]
