略论曹魏时期士家的地位

曹魏时期,战乱频繁。为了保证兵源,当时的统治者实行士家制。他们通过“当色配婚”、重“士亡法”等具体措施来确保兵源。而这些措施的实行,从侧面反映了当时士家社会地位的低下。

Reviewer assignment algorithms for peer review automation: A survey

Assigning paper to suitable reviewers is of great significance to ensure the accuracy and fairness of peer review results. In the past three decades, many researchers have made a wealth of achievements on the reviewer assignment problem (RAP). In this survey, we provide a comprehensive review of the primary research achievements on reviewer assignment algorithm from 1992 to 2022. Specially, this survey first discusses the background and necessity of automatic reviewer assignment, and then systematically summarize the existing research work from three aspects, i.e., construction of candidate reviewer database, computation of matching degree between reviewers and papers, and reviewer assignment optimization algorithm, with objective comments on the advantages and disadvantages of the current algorithms. Afterwards, the evaluation metrics and datasets of reviewer assignment algorithm are summarized. To conclude, we prospect the potential research directions of RAP. Since there are few comprehensive survey papers on reviewer assignment algorithm in the past ten years, this survey can serve as a valuable reference for the related researchers and peer review organizers.

Patterns of Nonverbal Adaptation in Supportive Interactions

This study seeks initial evidence for the patterns of nonverbal adaptation predictive of emotional improvement after a troubles talk conversation. A total of 128 dyads composed of two unacquainted individuals engaged in a 5-minute conversation about a stressful event, and the nonverbal behaviors of both the supportive listener and discloser were coded for immediacy. We detected a general pattern of matching between interlocutors, which was positively associated with disclosers’ reported emotional improvement above and beyond listener immediacy. Importantly, we found primary support for a discloser-matching model whereby emotional improvement is a function of disclosers matching highly immediate listeners but no support for a listener-matching model whereby emotional improvement is a function of listeners matching disclosers to signal empathy.     

Impact of Increased Academic Intensity on Transfer Rates: An Application of Matching Estimators to Student-Unit Record Data

The impact of increased academic intensity on transfer rates from community colleges to 4-year institutions has been estimated only from observational data, with the possibility of selection bias. This study uses matching estimators to overcome possible selection bias and estimate the causal impact of increased academic intensity on transfer rates. Using student unit record data from Tennessee for the years 1995 through 2004, I find that taking 12 or more credit hours increases the probability of transfer from between 11% and 15%.

Influencing the Probability for Graduation at Four-Year Institutions: A Multi-Model Analysis

The purpose of this study is to identify student and institutional characteristics that influence the probability for graduation. The study delves further into the probability for graduation by examining how far the student deviates from the institutional mean with respect to academics and affordability; this concept is referred to as the “match.” The validity of the matching model is tested using a multivariate analysis with select variables from the Beginning Postsecondary Study: 1996/2001 (BPS:96/01) and the Integrated Postsecondary Education Data System (IPEDS). Traditional multivariate models examine the importance of both student and institutional characteristics but assume the two are independent of one another. This study is different in that it uses the matching model to examine the relationship between student and institutional characteristics. The results are compared to more frequently used models and show that the relationship between students and their institutions plays an important role in understanding the probability for graduation.
