Contemplating the new DSM-V: Considerations from psychologists who work with school children.

The standard psychiatric classification system, the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision; DSM-IV-TR; American Psychiatric Association, 2000), is about to be updated. This is important because the DSM-IV-TR, a touchstone document for service providers across several disciplines, contains only some of the conditions reported in the vast developmental/learning, psychiatric, and health literature that are known to hamper school success. Practicing psychologists who work with school-age children and those who conduct educational research confront further limitations when using DSM-IV-TR or the commonly used special education scheme (the Individuals With Disabilities Education Act [IDEA], 2004). IDEA has limited heuristic potential because it was devised for educational administrative purposes, whereas the DSM-IV-TR is a medical nosological system with little concern for school issues. Neither system fully informs needed studies of epidemiology, natural history, and disorder-specific causes and treatments. This article provides a rationale for a set of proposed changes to the new DSM-V and explains how adopting these changes will benefit psychologists concerned with understanding and treating school-age children.

You cannot choose what is not on the menu--Obstacles to and reasons for the inclusion of relational processes in the DSM-V: Comment on the special section.

Relational diagnosis has crucial importance in clinical treatment, but its development and inclusion in systems of classification such as the Diagnostic and Statistical Manual has been constrained by a number of factors. First, there is little consensus about what relational assessment and/or diagnosis entails. A second obstacle is the innate complexity of relational assessment and diagnosis, which results in a lack of definitive, well-accepted, evidence-based operational definitions of difficulties. Third, empirical testing of relational issues has lagged well behind the development of elegant theory. A fourth significant block to including relational disorders in the DSM is the discomfort engendered in some quarters about labeling social difficulties as disorders. Finally, the political process that is part of the evolution of diagnostic systems poses difficulties in the acceptance of new disorders or dimensions. This comment on the articles in the special section on relational disorders of the Journal of Family Psychology addresses how each of these articles contributes to overcoming these constraints.

How psychology erodes personhood.

For the purposes of addressing some of our most pressing dilemmas and deficiencies today, in both our society and the field of psychology, it is helpful to think of the last 115 years or so as an evolution, in many quarters, from Victorian character to a painful kind of "empty self" to an even more devastating kind of fragmentation I dub "multiple self." I explore ways in which the DSM is a more or less witting carrier of these troubling forms of personhood, and argue there is no more pressing challenge for us than to recapture part of what we have lost, some sense of character and inviolable integrity, albeit a more flexible one than inhabited the Victorian era, and bring them to life in our era.

能源互联网对电力需求侧管理变革的影响

国家工业和信息化部发布《工业领域电力需求侧管理专项行动计划(2016-2020年)》,以促进工业企业科学、安全、节约、智能用电,实现以较低电力消费增长创造更多工业增加值产出。该文旨在研究能源互联网的发展对电力需求侧管理(power demand side management,DSM)的变革影响。首先分析了电力需求侧管理的基本架构,然后介绍了能源互联网的物理层、数据层、应用层3个层次的重要特征,并进一步详细分析了以上3个层次对电力需求侧管理的影响。最后,给出了一种符合能源互联网理念的工业园区电力需求侧管理技术体系。     

Quantification of hesperidin in citrus-based foods using a fungal diglycosidase

A simple enzymatic–spectrophotometric method for hesperidin quantification was developed by means of a specific fungal enzyme. The method utilises the diglycosidase α-rhamnosyl-β-glucosidase (EC 3.2.1.168) to quantitatively hydrolyse hesperidin to hesperetin, and the last is measured by its intrinsic absorbance in the UV range at 323 nm. The application of this method to quantify hesperidin in orange (Citrus sinensis) juices was shown to be reliable in comparison with the standard method for flavonoid quantification (high performance liquid chromatography, HPLC). The enzymatic method was found to have a limit of quantification of 1.8 μM (1.1 mg/L) hesperidin, similar to the limit usually achieved by HPLC. Moreover, it was feasible to be applied to raw juice, without sample extraction. This feature eliminated the sample pre-treatment, which is mandatory for HPLC, with the consequent reduction of the time required for the quantification.
