Moving beyond the duality of personal benefits and privacy risks, we theorize that users hold social considerations (i.e., social benefits and risks) that underlie their acceptance decisions. To test our propositions, we chose the context of COVID-19 contact tracing apps and conducted a qualitative pre-study and longitudinal quantitative main study with 589 participants from Germany and Switzerland. Our findings confirm the prominence of individual privacy calculus in explaining intention to use and actual behavior. While privacy risks are a significant determinant of intention to use, social risks (operationalized as fear of mass surveillance) have a notably stronger impact. Our mediation analysis suggests that social risks represent the underlying mechanism behind the observed negative link between individual privacy risks and contact tracing apps' acceptance. Furthermore, we find a substantial intention-behavior gap.}, language = {en} } @article{MuehlbauerGranacherBordeetal.2017, author = {Muehlbauer, Thomas and Granacher, Urs and Borde, Ron and Hortobagyi, Tibor}, title = {Non-Discriminant Relationships between Leg Muscle Strength, Mass and Gait Performance in Healthy Young and Old Adults}, series = {Gerontology}, volume = {64}, journal = {Gerontology}, number = {1}, publisher = {Karger}, address = {Basel}, issn = {0304-324X}, doi = {10.1159/000480150}, pages = {11 -- 18}, year = {2017}, abstract = {Background: Gait speed declines with increasing age, but it is unclear if gait speed preferentially correlates with leg muscle strength or mass. Objective: We determined the relationship between gait speed and (1) leg muscle strength measured at 3 lower extremity joints and (2) leg lean tissue mass (LTM) in healthy young (age: 25 years, n = 20) and old (age: 70 years, n = 20) adults. Methods: Subjects were tested for maximal isokinetic hip, knee, and ankle extension torque, leg LTM by bioimpedance, and gait performance (i.e., gait speed, stride length) at preferred and maximal gait speeds. Results: We found no evidence for a preferential relationship between gait performance and leg muscle strength compared with gait performance and leg LTM in healthy young and old adults. In old adults, hip extensor strength only predicted habitual gait speed (R-2 = 0.29, p = 0.015), whereas ankle plantarflexion strength only predicted maximal gait speed and stride length (both R-2 = 0.40, p = 0.003). Conclusions: Gait speed did not preferentially correlate with leg muscle strength or leg LTM, favoring neither outcome for predicting mobility. Thus, we recommend that both leg muscle strength and leg LTM should be tested and trained complementarily. Further, hip and ankle extension torque predicted gait performance, and thus we recommend to test and train healthy old adults by functional integrated multiarticular rather than monoarticular lower extremity strength exercises.}, language = {en} } @article{ChaabeneNegraCapranicaetal.2019, author = {Chaabene, Helmi and Negra, Yassine and Capranica, Laura and Prieske, Olaf and Granacher, Urs}, title = {A Needs Analysis of Karate Kumite With Recommendations for Performance Testing and Training}, series = {Strength and conditioning journal}, volume = {41}, journal = {Strength and conditioning journal}, number = {3}, publisher = {Lippincott Williams \& Wilkins}, address = {Philadelphia}, issn = {1524-1602}, doi = {10.1519/SSC.0000000000000445}, pages = {35 -- 46}, year = {2019}, abstract = {An effective training program needs to be customized to the specific demands of the redpective sport.

Dissociative and "falling from grace" theories suggest that mobility is stressful due to the weakening of social ties, feelings of alienation, and loss of status. In light of these theories, it is a puzzle that the majority of quantitative studies in this area have shown null results. Our approach to resolve the puzzle is two-fold. First, we argue for a broader conception of the mobility process than is often used and thus focus on intragenerational occupational class mobility rather than restricting ourselves to the more commonly studied intergenerational mobility. Second, we argue that self-reported measures may be biased by habituation (or "entrenched deprivation"). Using nurse-collected health and biomarker data from the UK Household Longitudinal Study (2010-2012, N = 4,123), we derive a measure of allostatic load as an objective gauge of physiological "wear and tear" and compare patterns of mobility effects with self-reports of health using diagonal reference models. Our findings indicate a strong class gradient in both allostatic load and self-rated health, and that both first and current job matter for current well-being outcomes. However, in terms of the effects of mobility itself, we find that intragenerational social mobility is consequential for allostatic load, but not for self-rated health. Downward mobility is detrimental and upward mobility beneficial for well-being as assessed by allostatic load. Thus, these findings do not support the idea of generalized stress from dissociation, but they do support the "falling from grace" hypothesis of negative downward mobility effects. Our findings have a further implication, namely that the differences in mobility effects between the objective and subjective outcome infer the presence of entrenched deprivation. Null results in studies of self-rated outcomes may therefore be a methodological artifact, rather than an outright rejection of decades-old social theory.}, language = {en} } @article{OhlertBoos2020, author = {Ohlert, Clemens and Boos, Pauline}, title = {Auswirkungen der Digitalisierung auf Geschlechterungleichheiten}, series = {Arbeit}, volume = {29}, journal = {Arbeit}, number = {3-4}, publisher = {De Gruyter Oldenbourg}, address = {Berlin}, issn = {0941-5025}, doi = {10.1515/arbeit-2020-0015}, pages = {195 -- 218}, year = {2020}, abstract = {Ausgehend von der Debatte um die Genderaspekte der Digitalisierung der Arbeit untersuchen wir den Zusammenhang zwischen der Nutzung digitaler Technologien und der Entwicklung von Geschlechterungleichheiten empirisch.

It is therefore remarkable that organizations as drivers of digitalization and as places for social integration have been widely overlooked so far.

Therefore, a look at the reciprocal relationship between organizations, digitalization, and gender is needed. The article provides answers to the question of whether and how organizations (re)produce, reinforce, or diminish gender-specific inequalities during their digital transformations. On the one hand, gender inequalities emerge when organizations use post-bureaucratic concepts through digitalization. On the other hand, gender inequalities are reproduced when organizations either program or implement digital technologies and fail to establish control structures that prevent gender biases. This article shows that digitalization can act as a catalyst for inequality-producing mechanisms, but also has the potential to mitigate inequalities.

However, there exists limited guidance on specific design choices for future-related Delphi surveys. Objective: We test whether or not small adjustments to the Delphi survey can increase certainty (i.e., reduce variation) in expert predictions on immigration to the EU in 2030. Methods: Based on a two-round Delphi survey with 178 migration experts, we compare variation and subjective confidence in expert predictions and assess whether additional context information (type of migration flow, sociopolitical context) promotes convergence among experts (i.e., less variation) and confidence in their own estimates. Results: We find that additional context information does not reduce variation and does not increase confidence in expert predictions on migration. Conclusions: The results reaffirm recent concerns regarding the limited scope for reducing uncertainty by manipulating the survey setup. Persistent uncertainty may be a result of the complexity of migration processes and limited agreement among migration experts regarding key drivers.
