Commentary on “Personality traits and the classification of mental disorders: Toward a more complete integration in DSM-5 and an empirical model of psychopathology”.

Comments on the original article Personality traits and the classification of mental Disorders: Toward a more complete integration in DSM–5 and an empirical model of psychopathology by Robert F. Krueger and Nicholas R. Eaton (see record 2010-13810-003). This article develops the larger theme that the fundamental quantitatively developed architecture of personality provides a sound base for classifying all areas of psychopathology and, more specifically, should underlie the current effort to revise the classification of personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). My commentary is organized around what I perceive to be four significant problems with the proposed change to a trait-based system: (1) unfamiliarity to clinicians (and possibly unfeasibility), (2) lack of clinical utility, (3) the preliminary quality of the science upon which the proposed change is based, and (4) harmful effects on the diagnosis of borderline personality disorder (BPD).

Solvent extraction and separation of light rare earth elements (La,Pr and Nd) in the presence of lactic acid as a complexing agent by Cyanex 272 in kerosene and the effect of citric acid,acetic acid and Titriplex Ⅲ as auxiliary agents

At present, the use of rare earth elements(REEs) has become an inevitable necessity in many modern industries. In general, liquid extraction is the best commercial method for extracting REEs due to its ability to control high volumes of liquids with electrical load. With the aim of improving a separation technology that would be superior to the existing extraction systems, the extraction behaviors of La(Ⅲ),Pr(Ⅲ), and Nd(Ⅲ) from an HCI medium with Cyanex 272 in the presence of the complexing agent lactic acid(HLac) and auxiliary agents citric acid(H_3 Cit), acetic acid(HAc), and Titriplex Ⅲ have been reported.The effect of pH and lactic acid concentration has been examined. The use of lactic acid as a complexing agent leading to a high extraction of REEs with Cyanex 272 at pH = 5 was compared with systems without lactic acid. The results show that the use of acetic acid along with lactic acid leads to an increase in the extraction percentage of LREEs. While use of citric acid and Titriplex Ⅲ reduces the extraction percentage of LREEs. Finally, the presence of Titriplex Ⅲ together with lactic acid could lead to an increase in the separation factor of Pr and Nd.

Facts, paradigms, and anomalies in the acceptance of energy psychology: A rejoinder to McCaslin’s (2009) and Pignotti and Thyer’s (2009) comments on Feinstein (2008a).

Allegations of selection bias and other departures from critical thinking in Feinstein (see record 2008-07317-008) found in the Pignotti and Thyer (see record 2009-08897-011), and the McCaslin (see record 2009-08897-010) commentaries, are addressed. Inaccuracies and bias in the reviewers’ comments are also examined. The exchange is shown to reflect a paradigmatic clash within the professional community, with energy psychology having become a lightning rod for this controversy. While postulated "subtle energies" and "energy fields" are entangled in this debate, the most salient paradigm problem for energy psychology may simply be that accumulating reports of its speed and power have not been explained using established clinical models.
