Ego impairment in schizophrenia as reflected in the Object Sorting Test.

Matched groups of schizophrenics and neurotics (a group which also included personality disorders), were compared on their performance on the Object Sorting Test. The schizophrenics could be significantly differentiated from the neurotics (and personality disorders) by virtue of their conceptualizations involving open-private ideas (à la McGaughran and Moran, 1956), inappropriate sorting, peculiar verbalizations, and perseverative thinking. The results are related to ego impairment in schizophrenia, and add to the capacity of this test of conceptual thinking to distinguish the thinking activity of schizophrenics from that of most other psychiatric patients.

School performance and disciplinary problems among abused and neglected children.

Investigated the relationship of child abuse and neglect to academic achievement and discipline problems in a school-age population. A representative community sample of 420 maltreated children in kindergarten through Grade 12 were matched with 420 nonmaltreated children in the same community. Using social service and school records as the sources of data, the authors found maltreated children performed significantly below their nonmaltreated peers in standardized tests and grades and were more likely to repeat a grade. Maltreated children also had significantly more discipline referrals and suspensions. Of the maltreated children, neglected children showed the poorest outcomes on academic performance, and physically abused children showed the most discipline problems. Variations in maltreatment effects by grade level, public assistance status, and gender are also described. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Substantiation of child abuse and neglect reports.

A representative sample of 796 sexual abuse, 198 physical abuse, and 880 child neglect reports in New York State in 1985 was examined to identify case factors that predict the substantiation of the reports following an investigation by child protective services. This issue has taken on added significance as the number of child maltreatment reports continues to rise, whereas the percentage of those being substantiated declines. Regression analyses revealed that reports from professionals were substantiated at a significantly higher rate than reports from nonprofessionals for all types of maltreatment. These analyses further revealed that part of the effect of source of report was due to differences between professional and nonprofessional reports in the types of actions taken after the report was received. The most important predictors of substantiation, after source of report, were the variables that reflected the case investigatory process. The data also showed that background characteristics, such as the child's ethnicity or the number of children in the household, had some impact on the outcome of the investigation and that this varied as a function of the type of maltreatment.

The effects of night ventilation technique on indoor thermal environment for residential buildings in hot-humid climate of Malaysia

This study investigates the effectiveness of night ventilation technique for residential buildings in hot-humid climate of Malaysia. This paper firstly presents the results of a survey on usage patterns of windows and air-conditioners in typical Malaysian residential areas. Secondly, the effects of different natural ventilation strategies on indoor thermal environment for Malaysian terraced houses are evaluated based on the results of a full-scale field experiment. The results show that the majority of occupants tend to apply not night ventilation but daytime ventilation in Malaysian residential areas. It can be seen from the field experiment that night ventilation would provide better thermal comfort for occupants in Malaysian terraced houses compared with the other ventilation strategies in terms of operative temperature. However, when the evaporative heat loss of occupants is taken into account by using SET*, the night ventilation would not be the superior technique to the others in providing daytime thermal comfort mainly due to the high humidity conditions. Therefore, the indoor humidity control during the daytime such as by dehumidification would be needed when the night ventilation technique is applied to Malaysian terraced houses. Otherwise, full-day ventilation would be a better option compared with night ventilation.     

Side‐Directed Transfer and Presystemic Metabolism of Selenoneine in a Human Intestinal Barrier Model

Scope : Selenoneine, a recently discovered selenium (Se) species mainly present in marine fish, is the Se analogue of ergothioneine, a sulfur‐containing purported antioxidant. Although similar properties have been proposed for selenoneine, data on its relevance to human health are yet scarce. Here, the transfer and presystemic metabolism of selenoneine in an in vitro model of the human intestinal barrier are investigated. Methods and results : Selenoneine and the reference species Se‐methylselenocysteine (MeSeCys) and selenite are applied to the Caco‐2 intestinal barrier model. Selenoneine is transferred in higher amounts, but with similar kinetics as selenite, while MeSeCys shows the highest permeability. In contrast to the reference species, transfer of selenoneine is directed toward the blood side. Cellular Se contents demonstrate that selenoneine is efficiently taken up by Caco‐2 cells. Moreover, HPLC/MS‐based Se speciation studies reveal a partial metabolism to Se‐methylselenoneine, a metabolite previously detected in human blood and urine. Conclusions : Selenoneine is likely to pass the intestinal barrier via transcellular, carrier‐mediated transport, is highly bioavailable to Caco‐2 cells and undergoes metabolic transformations. Therefore, further studies are needed to elucidate its possible health effects and to characterize the metabolism of selenoneine in humans.     

Fiber formation and properties of polyester/lignin blends

Thermotropic liquid crystalline polyesters with varied chemical structure are synthesized by melt transesterification polycondensation. They are employed as matrix for blends with lignin materials to obtain melt-spinnable precursors for carbon fibers. The lignin samples are carefully purified by fractionation, enzymatic removal of reducing sugars, and subsequent modification of the terminal OH groups. Effective melt blending is achieved with liquid-crystalline aromatic–aliphatic polyesters having melting ranges that match the softening temperature of the lignin fractions, which is necessary to prevent thermal decomposition of the lignin. Polyester/lignin blends are partially compatibilized, phase-separated materials. The polyester/lignin materials are melt-spun successfully. The fiber properties depend on the lignin purification process. X-ray scattering reveals that orientation in lignin-containing fibers is maintained. First experiments show that the fibers can be converted successfully to carbon fibers by thermal annealing procedures. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136, 48257.
