Perceived risk of using shared mobility services during the COVID-19 pandemic

The COVID-19 pandemic has caused our daily routines to change quickly. The pandemic provokes public fear, resulting in changes in what modes of transport people use to perform their daily activities. It is imperative for transportation authorities to properly identify the different degrees of behavioral change among various social groups. A major factor that can substantially explain individuals’ behavioral changes is the personal risk perceptions toward using shared mobility solutions. Thus, this study explores the risk that individuals perceive while using public transit and ridesharing services (as the most widespread forms of shared mobility) during the COVID-19 pandemic. To do so, we designed and implemented a multidimensional travel-behavior survey in the Chicago metropolitan area that comprises socio-demographic information and retrospective questions related to attitudes and travel behavior before and during the pandemic. Utilizing a bivariate ordered probit modeling approach to better account for the potential correlation between unobserved factors, we simultaneously modeled the perceived risk of exposure to the novel coronavirus in case of riding transit and using ridesharing services. A wide range of factors is found to be influential on the perceived risk of using shared mobility services, including the socio-demographic attributes, built environment settings, and the virus spread. Further, our results indicate that the mitigation strategies to increase the ridership of shared mobility services should be adaptive considering the spatial variations.     

ICU谵妄的预防：早期活动

ICU谵妄发生率高、识别率低,可显著延长ICU平均住院时间、增加病死率、加重转出ICU后认知功能障碍.但目前缺乏有效的谵妄预防措施.综合干预措施可降低谵妄的发生,其中早期活动是治疗的关键.ICU早期活动安全可行,可降低谵妄的发生及缩短谵妄的持续时间,改善患者预后.ICU中开展早期活动治疗是基于＆quot;ABCDE＆quot;集束化干预措施的前提下,中断镇静后尽早开始肢体功能锻炼和职业治疗,包括从先被动后主动的关节活动,到双腿下垂坐到床缘,进一步下床坐到轮椅上甚至步行活动,是早期活动的基本流程.     

Performance of an Adapted Version of the Timed Up-and-Go Test in People with Cognitive Impairments

In clinical practice, older people with cognitive impairment may have difficulties to understand the instructions of the Timed Up-and-Go (TUGT) test and present a bad performance. The purpose of this study was to identify differences in the TUGT performance, in an adapted version, between older adults with preserved cognition (PC), mild cognitive impairment (MCI) and Alzheimer's disease (AD), and to identify the association between the adapted TUGT performance and cognition among groups. A cross-sectional study was conducted with 118 community-dwelling older adults divided in three groups: PC (n?=?40), MCI (n?=?40) and AD (n?=?38). The evaluation was composed by the adapted TUGT and cognitive assessment (Addenbrooke's Cognitive Examination and Frontal Assessment Battery). Only the cadence of TUGT presented significant difference between groups, specifically between AD versus MCI and PC groups. The main correlations were found between time of TUGT with fluency domain and global cognitive function, especially in the AD Group. The findings contribute to the understanding of how cognition interferes on functional mobility in older people with MCI and AD. The adapted TUGT is easy to perform in clinical practice and can be useful when assessing mobility in people with cognitive impairment.     

Functional Mobility in a Divided Attention Task in Older Adults With Cognitive Impairment

ABSTRACT. Motor disorders may occur in mild cognitive impairment (MCI) and at early stages of Alzheimer's disease (AD), particularly under divided attention conditions. We examined functional mobility in 104 older adults (42 with MCI, 26 with mild AD, and 36 cognitively healthy) using the Timed Up and Go test (TUG) under 4 experimental conditions: TUG single task, TUG plus a cognitive task, TUG plus a manual task, and TUG plus a cognitive and a manual task. Statistically significant differences in mean time of execution were found in all four experimental conditions when comparing MCI and controls (p < .001), and when comparing MCI and AD patients (p < .05). Receiver-operating characteristic curve analyses showed that all four testing conditions could differentiate the three groups (area under the curve > .8, p < .001 for MCI vs. controls; area under the curve > .7, p < .001 for MCI vs. AD). The authors conclude that functional motor deficits occurring in MCI can be assessed by the TUG test, in single or dual task modality.     

Challenging Merton's Protestantism‐Science Hypothesis: The Historical Impact of Sacerdotal Celibacy on German Science and Scholarship

Denominational differences in the number of scientists produced in Germany during the period 1550 to 1900 are linked to the historical impact of Catholic celibate and Protestant noncelibate clergy households. Protestant leadership in science is largely attributable to the development of a new social mobility pattern among descendants of their clergy that enhanced the pastorate's ability to convey cultural and social capital to their marrying offspring, something denied to Catholic clergy. By reference to German historical developments, I show that the contributions of clerical households, far from being limited to the natural sciences, were equally in evidence across most other areas of scholarly endeavor. A discussion of the theoretical implications of these findings provides a comparative analysis of Protestant to Catholic scholarly achievements in general, and of scientific achievements in particular, as well as a critical assessment of Robert K. Merton's theorizing on the subject.     

Do specific types of networking predict specific mobility outcomes? A two-year prospective study

Previous research has established a general relation between networking and career outcomes, as postulated by theories on protean careers and career self management. We suggest that specific facets of networking behavior differentially affect specific career mobility outcomes over time. In a 2-year prospective study, we examined the impact of six facets of networking on the likelihood receiving a promotion, changing employer, or remaining in the current position. Results show that internal networking is related to promotions and change of employer, whereas external networking is only related to change of employer. Moreover, internal networking shows a differential relation with the temporal proximity of promotions where using internal contacts predicts promotions in the first year and building and maintaining internal contacts predict promotions in the second year. However, this temporal pattern did not hold for external networking, where only maintaining external contacts predicted change of employer in the second year.     

阶层流动的“双刃剑”效应及其心理机制

阶层流动是指人们在社会分层体系中相对位置的变化。人们普遍预期,向上流动促进个体发展和社会进步。然而近期研究也表明,向上流动还可能损害个体健康和主观幸福感,使人们低估和容忍社会不平等,并反对再分配。地位认同、贫富归因倾向以及系统公正信念能够解释向上流动的双刃剑效应。未来研究需要进一步澄清向上流动感知的具体表现,深入考察向上流动影响的心理机制,探索促进阶层流动积极效应发挥的干预方法。     

Social Identity and Spatial Behaviour: The Relationship between National Category Salience, the Sense of Home, and Labour Mobility across National Boundaries

This study explores the impact of manipulating the salience of national categories upon the willingness of highly identifying Scots to take up either short-term or long-term jobs in Scotland as compared to England. The results support the hypotheses (a) that high-identifying Scots increase preference for intra- over extranational locations when national categories are salient, (b) that this effect is fully mediated by "fitting in"—that is, the sense of being "at home" in Scottish as compared to English locations, and (c) that these relationships only hold for long-term as opposed to short-term jobs. We discuss these results in terms of the impact of identity definitions upon spatialised action and the economic/political importance of this relationship.

Understanding pro‐environmental intentions by integrating insights from social mobility,cosmopolitanism, and social dominance

To offer an integrative account bridging individuals’ sociocultural orientations with pro‐environmentalism, the current research tested the mediating and moderating relationships among pro‐environmental intentions and three person‐level factors: perceived social mobility, cosmopolitan orientation, and social dominance orientation (SDO). With a Singaporean college student sample (N = 220), we found support for the hypothesized second‐stage moderation model that perceived social mobility positively predicts cosmopolitan orientation, and in turn, cosmopolitan orientation is moderated by SDO to positively predict pro‐environmental intentions. Specifically, lower levels of SDO strengthen the pro‐environmental advantages of endorsing higher levels of cosmopolitan orientation. These findings add novel knowledge to the environmental psychology literature by advancing an integrative approach that demonstrates how the interplay of people's perceptions about the social, cultural, and group standing impacts their likelihood to engage in pro‐environmental actions. We discuss the implications that an egalitarian worldview toward other cultures, social groups, and human–nature relations might be the key to addressing the global challenge of climate change.
