Personality of social robots perceived through the appearance

Past research showed that people are able to perceive the personality of others at zero acquaintances. There are two main ways, verbal and non-verbal methods, which play an important role for one in perceiving personality of others. Extensive research was conducted in relating personality with verbal, paralinguistic and gestures cues. However, there are not much research, to our knowledge, that relates the appearance and perceived personality of robots. The main objective of this research is to relate individual design features with big five perceived personality of the robots. We used the results of rated perceptions across 100 pictorial images of robots and relate the results with the 40 individual design features using General Linear Model (GLM). The initial results of the GLM analysis showed that participants' rating of personality of robot fell along the dimension of perceived friendliness which is a common rotation of extroversion and agreeableness. Some relationships were found between humanlike design features and perceived friendliness of robots. Since participants are more familiar with humans, participants perceived robots with humanlike features friendlier than the others. Some other findings such as color and surface material were found related with participants' perceived friendliness as well. In the future, we will work on the analysis of the main and interaction effects of individual features on user's perceived friendliness.     

Cyclin-dependent kinase 5--a neuronal killer?

In dividing cells, cyclin-dependent kinases (Cdks) are cell cycle-associated protein kinases that regulate proliferation, differentiation, senescence, and apoptosis. In neurons that no longer divide, deregulation of Cdks, especially Cdk5, occurs in many neurological disorders, including Alzheimer's disease (AD) and Parkinson's disease (PD). Cdk5 is a unique member of the Cdk family because it does not play a critical role in cell cycle progression, and it is not activated by a cyclin. Instead, Cdk5 normally is activated by the regulatory protein p35. This Cdk5/p35 activity has emerged as an important regulator of proper development of the mammalian central nervous system. In vitro studies suggest that aberrant activation of Cdk5 by an endogenous truncated version (p25) of p35 might be a key event in the process of neurodegeneration. One enzyme responsible for cleavage of p35 to form p25 is calpain, a calcium-activated protease that has been shown to be involved in neuronal cell death. Recent studies provided important in vivo evidence that hyperactivation and redistribution of Cdk5 by p25 plays an essential role in the phosphorylation of "pathological" substrates (such as tau) and the cell death of neurons in experimental models of AD and PD. Because amyloid beta peptide, the primary neurotoxic component of amyloid plaques in AD, has been shown to increase the conversion of p35 to p25, aberrant activation of Cdk5 by p25 might be a pathway connecting amyloid beta toxicity to tau hyperphosphorylation in AD.     

历史的终结还是目标：作为历史哲学家的弗朗西斯·福山

美国学者弗朗西斯·福山在冷战结束之后,因出版《历史的终结及最后之人》,成为当今世界引人注目的战略思想家。自此之后,福山继续对世界局势的现状及其未来走向,做出种种分析和展望。福山的这些论著,展现了当代的一种思辨历史哲学。在过去的三十年中,鉴于世界局势的不断变化,福山也补充、修正着自己的立场。不过从其2018年出版的《认同：追求尊重和仇恨政治》来看,福山的历史观基本未变,仍然从唯心主义的视角探究历史的演化。他始终认为世界历史发展尽管多有曲折,但将沿着一个方向走向大同：人类历史不是走向终结,而是发现了一个共同的目标。     

Institutional care for elders in rural China

The long-term care (LTC) literature has been generally associated with industrialized countries. However, LTC needs are increasing in the developing world at a rate that far exceeds than experienced by industrialized countries. Using China as a case study, the purpose of this report is to provide an example of an emerging institutional care system for rural elders in a rapidly developing country. It covers two major domains of the system: service delivery and financing. The report presents several main issues involved in the development of institutional care for elders and discusses relevant policy implications.

An overview of maritime waterway quantitative risk assessment models

The safe navigation of ships, especially in narrow shipping waterways, is of the utmost concern to researchers as well as maritime authorities. Many researchers and practitioners have conducted studies on risk assessment for maritime transportation and have proposed risk reduction/control measures accordingly. This article provides a detailed review and assessment of various quantitative risk assessment models for maritime waterways. Eighty-seven academic papers and/or project reports are summarized and discussed. The review then proceeds to analyze the frequency and consequence estimation models separately. It should be pointed out that we further summarize the advantages and disadvantages of frequency estimation models and provide recommendations for their application. From the overview, we find that the quantification of the impact of human error is of great importance and should be considered in future studies. Possible solutions are also proposed in the discussions.     

A Note on Generalized Functional Linear Model and Its Application

Motivated by a biomarker study for colorectal neoplasia, we consider generalized functional linear models where the functional predictors are measured with errors at discrete design points. Assuming that the true functional predictor and the slope function are smooth, we investigate a two-step estimating procedure where both the true functional predictor and the slope function are estimated through spline smoothing. The operating characteristics of the proposed method are derived; the usefulness of the proposed method is illustrated by a simulation study as well as data analysis for the motivating colorectal neoplasia study.     

Asymptotic properties of mean survival estimate based on the Kaplan-Meier curve with an extrapolated tail

Asymptotic distribution of the mean survival time based on the Kaplan-Meier curve with an extrapolated 'tail' is derived. A closed formula of the variance estimate is provided. Asymptotic properties of the estimator were studied in a simulation study, which showed that this estimator was unbiased with proper coverage probability and followed a normal distribution. An example is used to demonstrate the application of this estimator.     

Barefoot and in a German kitchen: federal parental leave and benefit policy and the return to work after childbirth in Germany

Since 1979 German federal maternity leave and benefit policy has given women incentives to stay at home and take care of their newborn and youngest children. In 1986 this leave and benefit policy was changed in several ways, turning it into a powerful instrument for delaying mothers' return to work after childbirth. Using a flexible duration dependence estimation technique for proportional hazards due to Prentice and Gloeckler (1978) and applied to grouped durations by Meyer (1987, 1990), we estimate post childbirth return to work hazards for women during the federally protected leave protection period and immediately upon completion of this leave period. During the leave mothers are less likely to return to work the longer is the time left in the leave protection period; however, this result cannot be attributed generally to high levels of maternity benefits. When the leave protection period ends, mothers with strong labor force attachment who are still on leave return to their jobs.The second author gratefully acknowledges financial support by the National German Science Foundation (Deutsche Forschungsgemeinschaft) (Grant No. Wa 547/2-1).
