The Medical Center's Impact in the Network to Sustain the Aged in the Community

A process is described to show how a Social Work Department of a Medical Center ascertained the need to offer a continuum of comprehensive services to a high risk elderly population. This includes aiding and participating with the board and administration of the Medical Center to develop a varied network of services programs. A community based program model is used to show the utilization of individual and group modalities in working with this age population. Clinical material is incorporated to emphasize that aging clients are accessible for psychosocial interventions and can utilize their ego strengths through group living and group counseling. Experiences will highlight that behavioral changes can be brought about through a reintegration of social, emotional, and environmental forces.     

Statistical properties of detrended fluctuation analysis

The main goal of this work is to consider the detrended fluctuation analysis (DFA), proposed by Peng et al. [Mosaic organization of DNA nucleotides, Phys. Rev. E. 49(5) (1994), 1685–1689]. This is a well-known method for analysing the long-range dependence in non-stationary time series. Here we describe the DFA method and we prove its consistency and its exact distribution, based on the usual i.i.d. assumption, as an estimator for the fractional parameter d. In the literature it is well established that the nucleotide sequences present long-range dependence property. In this work, we analyse the long dependence property in view of the autoregressive moving average fractionally integrated ARFIMA(p, d, q) processes through the analysis of four nucleotide sequences. For estimating the fractional parameter d we consider the semiparametric regression method based on the periodogram function, in both classical and robust versions; the semiparametric R/S(n) method, proposed by Hurst [Long term storage in reservoirs, Trans. Am. Soc. Civil Eng. 116 (1986), 770–779] and the maximum likelihood method (see [R. Fox and M.S. Taqqu, Large-sample properties of parameter estimates for strongly dependent stationary Gaussian time series, Ann. Statist. 14 (1986), 517–532]), by considering the approximation suggested by Whittle [Hypothesis Testing in Time Series Analysis (1953), Hafner, New York].     

Beyond High School

Abstract

This study examined interpersonal heterosexist discrimination by examining self-reported anti-gay behaviors of heterosexual college students. Respondents were 226 college students; 94.9% had perpetrated some form of discriminatory behavior and 32.7% had committed a behavior that was rated as moderately harmful or higher. A higher amount of self-reported discriminatory behavior was associated with being male, having more homophobic attitudes, and having lower GPAs. Discriminatory behaviors were not related to political ideology, religious influence, or interaction with gay men and lesbians. Neither discriminatory behaviors nor homophobic attitudes were related to academic year, age, membership in a social fraternity/sorority, or membership on an intercollegiate athletic team.     

书写绝望与反抗绝望--浙江三位先锋小说家创作评述

浙江三位先锋小说家余华、王彪、艾伟分别从人性的层面、欲望的层面、记忆的层面对存在进行了相同的极端书写,描绘出了一幅相同的绝望的生存景观,又都以各自的方式对这"绝望"进行着反抗.     

论维柯创造说及其对古希腊摹仿说的发展

维柯《新科学》在西方思想史上占据着特殊地位。维柯在《新科学》中提出一套关于创造的学说:(一)创造活动与摹仿、想象、记忆等功能密不可分,它们的整体构成"诗性智慧"。(二)以想象力为标准,可划分出两种创造:隐喻的想象与"重聚的"想象,后一种创造活动完全据有并呈显创造的本质。维柯创造说继承并发展了古希腊的摹仿说,正确揭示出摹仿与想象在创造中的关系。

基于LSTM神经网络的金融时间序列预测

本文提出将小波分析与纳入时间序列依赖特征的长短期记忆（LSTM）神经网络相结合，构建金融时间序列数据预测模型，以克服现有模型对金融时间序列数据非平稳、非线性、序列相关等复杂特征以及数据间非线性交互关系无法反映的缺陷。同时，以道琼斯工业指数日收盘价为例，探究LSTM神经网络对实际金融时间序列数据的预测能力，比较其与多层感知机、支持向量机、K近邻、GARCH四种模型的预测效果。实证结果表明LSTM神经网络具有更高的预测精度，能够有效预测金融时间序列数据的长短期动态变化趋势，说明了其对金融时间序列数据预测的适用性与有效性。此外，对金融时间序列数据进行小波分解与重构，可有效提高LSTM预测模型的泛化能力，以及对长短期动态趋势的预测精度。     

Aging with HIV: Historical and Intra-Community Differences in Experience of Aging with HIV

Gay men living with HIV/AIDS face a complex of health issues, including those associated with the aging process, long-term HIV infection (25 years or more), and side effects from Highly Active Anti-Retroviral Therapy (HAART). If aging can increase marginalization, this is more likely for the aging HIV positive gay man, who is already marginalized for being queer and living with a stigmatizing disease. This article presents findings from a study of a long-running HIV support group. It locates the members, all gay men living with HIV, in a specific historical and political context to explore how feelings of loss and the struggle to sustain community affect long-term survivors and other older HIV+ gay men. We identify specific challenges presented by aging for men who contracted HIV early in the epidemic, contrasting them with those faced by men infected with the virus later in life. While both groups appear to struggle with a vision of what life could have been, had AIDS not forced loss and change, they also celebrate the community their shared plight has enabled.     

多变量过程自组织学习控制新方法及其实时实现

本文论述一种利用相联存储器系统的多变量自组织学习控制新方法及其实时实现。在线学习包含两个步骤:被控过程的动态输入—输出特性用仿视感控器的方式逐步存入一个相联存储器中,用来作为预测过程模型;依靠一种特殊的输出预测算法,利用预测过程模型并通过单步超前性能指标最优化来规划控制策略,经教练后的控制策略以同样的方式存入第二个相联存储器中。文中提出了一种特殊的采样和更新方法。通过仿真和实时应用证明了所述学习控制新方法的可行性。     

儿童拼图性识字的记忆研究

以艾宾浩斯的遗忘曲线为基本框架,通过拼图性学习和常规性学习两种不同学习生字方法的实验比较,对儿童识字的一般性规律进行研究。得到结论:拼图性识字在记忆的保持上优于常规性识字;拼图性识字在学习有笔画难度的字上优于常规性识字;拼图性识字同样符合艾宾浩斯的遗忘曲线规律。拼图性识字教学符合儿童以动作思维为主的认识特点,符合儿童心理的年龄特征,能提高对字形记忆的效果,让儿童可以有效、有趣、自主进行早期识字学习。
