Classism is overrated: Comment.

Comments on "Psychotherapy, classism, and the poor: Conspicuous by their absence" by Laura Smith (see record 2005-11834-002). This article might have improved Smith's argument that prejudice and oppression (classism) are significant obstacles preventing the poor from receiving psychological services if she had presented evidence to substantiate her claim that "psychology has fallen short in its services" (p. 687) to the poor in the first place. In fact, there is reason to believe that psychotherapists are meeting the mental health needs of the poor in some areas of the country. In Maine, the poor are eligible for Medicaid, which allows for mental health benefits that are more generous in some cases than those provided by private insurance. In addition, the poor in southern Maine may take advantage of programs that pay for mental health services in ways that the middle class cannot. Many psychologists in Maine do provide mental health services to the poor. This is not to say that barriers do not exist or that the mental health needs of the poor are being met. However, I think it is fair to challenge the premise of Smith's (2005) article that the poor either are not being served or are being disproportionately served compared with the nonpoor.

Classism is much more complex: Comment.

Comments on "Psychotherapy, classism, and the poor: Conspicuous by their absence" by Laura Smith (see record 2005-11834-002). Smith is to be commended for identifying a critical missing area in applied psychology: the inclusion of people who are poor into training, education, research, and practice. But in advocating for psychology to be inclusive, Smith used conceptualizations of social class and classism that do not address the complexity of social class and classism in psychology. First, the language Smith used to discuss social class was atheoretical. She used the terms social class, class, social status, the poor, and poverty to address social class as a construct, and she did not operationalize her terms. The second limitation in Smith's article was her aggregating and labeling of people who are poor. By categorizing people in this situation as "poor people" rather than as "people who are poor," Smith made "poor people" a dispositional attribute. Finally, Smith's conceptualization of classism does not consider the networks of power (Liu & Pope-Davis, 2003b) that are integral in maintaining and perpetuating inequality and marginalization. Because power is complex, conceptualizations of oppression and marginalization should be as well. Psychologists hoping to decrease inequality in society need to combat disparities with a clear idea of how social class and classism function.

铁纤维的气流分级效果研究

为了将不同直径分布范围的铁纤雏分离出来，根据平抛运动原理自行设计了气流分级装置，并在该装置上进行气流分级实验，得到不同直径分布范围的3个组分。借助扫描电镜和矢量网络分析仪对所得组分进行了分析．结果表明，分级后纤维的直径分布范围更加集中，电磁参数区别明显。其模拟反射率计算结果表明，直径较细的纤维吸波性能好。     

农用地定级两种因素法比较研究——以重庆市九龙坡区为例

以重庆市九龙坡区为例,对因素法定级的思路进行探讨,提出考虑外部性的因素法。分别用两种因素法对九龙坡区农用地进行定级,并对两种定级结果进行比较。与不考虑外部性的因素法相比,九龙坡区外部性对农用地级别的贡献率为46.02%,两种方法存在一定差异。外部性包括自然和社会经济的外部性,是客观存在的,在农用地质量评价时应予以考虑。     

Preparation of superhydrophobic silica‐based films by using polyethylene glycol and tetraethoxysilane

Preparation of superhydrophobic silica‐based films via sol‐gel process by adding polyethylene glycol (PEG4000) in the silica sol precursor solution has been developed. The casting films were prepared by casting the above solution on the glass and adding poor solvent on it or not. Surface roughness of the films was obtained by removing polymer from the films at high temperature. Then, the hydrophobic group on the surfaces was obtained by reaction with hexamethyldisilazane (HMDS). Characteristic properties of the as‐prepared surface of the films were analyzed by contact angle measurement, scanning electron microscopy (SEM), atomic force microscope (AFM), Fourier transform infrared (FT‐IR) spectrophotometer, and X‐ray photoelectron spectrometer (XPS). The results showed that the contact angles of the films were varied with the PEG weight fraction of the films, the solvent for the PEG solution, the reaction temperature and time, and adding poor solvent (n‐hexane) or not. However, the surface roughness has been controlled by adjusting the experimental parameters during the early period. The contact angle of the film that prepared by spraying the poor solvent (n‐hexane) onto each coating layer for four times after casting process was greater than 150°. It was difficult to obtain superhydrophobic surface without adding n‐hexane onto any coating layer in this system. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
