全面推进依法行政,为社会主义政治文明提供保证

社会主义政治文明是全面建设小康社会的重要目标,实现这一目标,必须依法治国。依法行政是依法治国基本方略的重要组成部分,对依法治国的实行具有决定性意义,是实现党对国家和社会领导的执政方式,对于推进社会主义民主政治建设具有重要作用,是建设社会主义政治文明的保证。对我国当前推进依法行政过程中存在的问题,应进一步更新观念,切实转变政府职能,提高行政机关工作人员素质,强化行政执法监督,全面推进依法行政,为社会主义政治文明建设提供保证。

A Semi‐empirical Bayesian Chart to Monitor Weibull Percentiles

This paper develops a Bayesian control chart for the percentiles of the Weibull distribution, when both its in‐control and out‐of‐control parameters are unknown. The Bayesian approach enhances parameter estimates for small sample sizes that occur when monitoring rare events such as in high‐reliability applications. The chart monitors the parameters of the Weibull distribution directly, instead of transforming the data as most Weibull‐based charts do in order to meet normality assumption. The chart uses accumulated knowledge resulting from the likelihood of the current sample combined with the information given by both the initial prior knowledge and all the past samples. The chart is adapting because its control limits change (e.g. narrow) during Phase I. An example is presented and good average run length properties are demonstrated.     

A Robust Control Chart for Monitoring the Mean of an Autocorrelated Process

Residual control charts are frequently used for monitoring autocorrelated processes. In the design of a residual control chart, values of the true process parameters are often estimated from a reference sample of in-control observations by using least squares (LS) estimators. We propose a robust control chart for autocorrelated data by using Modified Maximum Likelihood (MML) estimators in constructing a residual control chart. Average run length (ARL) is simulated for the proposed chart when the underlying process is AR(1). The results show the superiority of the new chart under several situations. Moreover, the chart is robust to plausible deviations from assumed distribution of errors.     

Spatio-temporal variation of natural and sexual selection in breeding populations of the coreid bug,Colpula lativentris (Heteroptera: Coreidae)

Spatio-temporal variations of lifetime reproductive succes (LRS) of both male and female individuals of a coreid bugColpula lativentris were measured and analyzed using the multiple regression method of Arnold and Wade (1984a, b). The standardized variance of LRS was larger in males than that in females as males often to secure mates for a long period whereas females could easily find mates and oviposit simply dependent on ovarial maturation. LRS was partitioned into 4 consecutive fitness components: (1) reproductive lifespan, (2) copulating efficiency, (3) guarding efficiency (for males) or oviposition efficiency (for females), and (4) number of eggs per clutch. In males copulating efficiency was the largest determining factor of LRS, whereas in females reproductive lifespan was the most important factor. Such tendencies were stable on both a yearly and local basis. Patterns of relative contribution of natural selection (reproductive lifespan and number of eggs per clutch) and sexual selection (copulating efficiency and guarding or oviposition efficiency) to LRS were clearly different between males and females. This sexual difference is, at least to some extent, thought to be brought about by sexual selection among males for mating opportunity, though no physical fight was observed among males. Directional selection on body length was found only in relation to the clutch size of females because large females tended to lay larger clutches. No significant directional selection was found in other fitness components.     

Serving Former Foster Youth and Homeless Students in College

ABSTRACT

Many universities have developed campus support programs for former foster youth and homeless college students; however, there are no studies focusing on long-term programs in the college-setting with a mentoring component that focuses on developing relationships with supportive adults. To address the gap, this study examined both mentors' and program staff's experience with providing services to students in a campus support program. The authors collected qualitative data from one success coach (i.e. program staff) and eight mentors through focus group meetings and interviews. Results indicated that the success coach reported the students in the program improved their overall academic performance, while most mentors did not know their mentees' grades. The success coach coordinated most services of the program, assigned financial and academic support, and made service referrals. Mentors helped their mentees to improve academic and independent living skills. However, mentors reported that they received limited support, especially when working with mentees with mental health problems. Recommendations to improve the program include: using a multidisciplinary team for students with mental health problems and adopting systematic approaches to better support mentors' services. Future studies should go beyond program staff and mentors to include students' perspectives regarding their experiences with receiving mentoring services.     

A new adaptive EWMA control chart using auxiliary information for monitoring the process mean

The adaptive memory-type control charts, including the adaptive exponentially weighted moving average (EWMA) and cumulative sum (CUSUM) charts, have gained considerable attention because of their excellent speed in providing overall good detection over a range of mean shift sizes. In this paper, we propose a new adaptive EWMA (AEWMA) chart using the auxiliary information for efficiently monitoring the infrequent changes in the process mean. The idea is to first estimate the unknown process mean shift using an auxiliary information based mean estimator, and then adaptively update the smoothing constant of the EWMA chart. Using extensive Monte Carlo simulations, the run length profiles of the AEWMA chart are computed and explored. The AEWMA chart is compared with the existing control charts, including the classical EWMA, CUSUM, synthetic EWMA and synthetic CUSUM charts, in terms of the run length characteristics. It turns out that the AEWMA chart performs uniformly better than these control charts when detecting a range of mean shift sizes. An illustrative example is also presented to demonstrate the working and implementation of the proposed and existing control charts.
