A deletion ahead of its time

An alleged defect in transformational treatment of syntax acquisition is the absence from child speech of certain predicted errors with ‘wh-’ constructions. In this paper, a theory of acquisition dynamics and intensive longitudinal data are brought to bear on this issue. The key observations involve an early precursor, at 24—28 months, of the relative clause. The analysis sheds light on two fundamental issues in transformational acquisition theory: The permissibility of simultaneous rule changes and whether a transformation can be acquired before the associated deep structure. The issues and analysis can be translated into non-transformational terms.     

工作特征对工作者的影响——要求-控制模型与工作要求-资源模型的比较

工作特征是指与工作相关的因素或属性, 它对工作者的身心健康有重要影响。通过对比研究发现, 虽然要求-控制模型(Demand-Control Model, 简称DC模型)将工作特征分为相对具体的工作要求、工作控制和社会支持, 工作要求-资源模型(Job Demands-Resources Model, 简称JD-R模型)则将工作特征划分为更为概括的工作要求和工作资源两个维度, 但是它们关注的结果变量都包含个体身心健康和组织工作绩效, 都强调了工作特征对工作者的影响。在今后的研究中, 应深入探讨不同职业中起关键作用的工作特征和不同资源与要求组合的作用, 进一步研究工作特征模型对不同特点个体和我国民众群体的适用性, 并尝试将研究成果应用于工作再设计的实践, 以促进工作者的职业健康。     

Infant Mental Health assessment: the use of DC 0-3 in an outpatient child psychiatric clinic in Scandinavia

The study focuses on Infant Mental Health data from an outpatient psychiatric clinic using the "Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood" (DC 0-3) and parental questionnaires, CBCL and ITSC. In total, 138 infants (aged 0-3) went through the diagnostic procedure. Sixty-eight per cent were diagnosed within Axis I, with regulatory disorder, disorder of affect and traumatic stress disorder being the most frequent diagnoses. In addition, 48% were classified as having a relationship disorder according to Axis II, with an additional 40% being considered to be at risk of developing a relationship disorder. The mothers' and fathers' ratings of their children's externalized and sensitivity problems were in agreement with the clinicians, but the ratings of internalized problems as well as relationship problems presented a more complex pattern.     

以树突状细胞为基础的前列腺癌免疫治疗的研究

探讨以人外周血单个核细胞（peripheral blood monouclear cells,PBMC）来源的树突状细胞（dendritic cell,DC）为基础的抗前列腺癌免疫作用。分离外周血PBMC,用重组人粒细胞巨噬细胞集落刺激因子（rhGM—CSF）和重组人白介素-4（rhIL-4）诱导PBMC产生DC。提取前列腺癌PC-3细胞总RNA,致敏DC并用流式细胞仪检测细胞的表面标志物CD14、CD40、CD80、CD86。致敏后的DC与淋巴细胞共同培养诱导产生特异性细胞毒性T淋巴细胞（cytotoxic Tlymphocyte,CTL）,用MTT细胞毒检测试剂盒检测特异性CTL对肿瘤细胞的杀伤率。结果总RNA致敏后的DC细胞CD40、CD80、CD86显著增高,CD14显著降低（P〈0．05）。前列腺癌组杀伤率（55．27＋9．76）与空白对照组杀伤率（36．75＋7．06）之间的差异有统计学意义（P=0．009〈0．05）。胃癌对照组杀伤率（36．75＋7．06）与空白对照组杀伤率（35．66＋7．85）之间差异无统计学意义（P=0．834〉0．05）。结论是经RNA致敏的DC可以诱导产生对前列腺癌细胞有特异性杀伤活性的CTL。     

The Safe-Range-Inventory (SRI): An assistance tool for optimizing the charging infrastructure for electric vehicles

Electric Vehicles (EVs) are propagated as an essential solution for reducing the carbon footprint of traffic activities. One essential barrier to the adoption of electromobility strategies in everyday life is the very limited driving range of typical EVs. A dense and reliable network of electric charging stations would enable safer and longer ranges. Modern fast-charging technologies provide additional possibilities to tactically and quickly re-charge EVs, but high implementation costs make it necessary to establish a mixed infrastructure consisting of cheap-but-slow and expensive-but-fast charging stations. We utilized the so-called Safe-Range-Inventory (SRI), a multidimensional assessment tool for capturing multi-facets of subjective range safety assessments. Using scenarios with different infrastructure settings, we revealed that the addition of just one fast-charging option drastically lowers range anxiety even under relatively short emergency range conditions. Additional fast-charging options did not have strong positive effects on the assessments but would amass very high costs. The SRI can assist in the planning of electric charging infrastructures in order to find the right balance between range safety and installation and maintenance costs.     

Comparing natural and abstract categories: A case study from computer science

In order to address the issue of whether abstract and concrete objects are categorized similarly, this paper looks at how computer scientists categorize the common concepts of their field. Using the methodology of Rosch, Mervis, Gray, Johnson, and Boyes-Braem (1976) and of Rosch and Mervis (1975) to identify the categorizations used by computer scientists, this study found that the categorization phenomena reported for concrete objects are quite general, operating over a wider range than was previously thought.     

Synesthesia: II. Psychophysical relations in the synesthesia of geometrically shaped taste and colored hearing

The psychophysical function in two synesthetic subjects, one with geometrically shaped taste and the other with colored hearing, is investigated. Each synesthete is compared with three control subjects. Pilot studies are used to construct appropriate response domains. Compared to controls, synesthetes give a restricted set of responses that are also asymmetric with respect to the range of choices available in various subsets of the response domain. A combination of absolute and relative effects is also distinctive of synesthetic percepts. It is concluded that synesthesia is a distinct phenomenon unlike ordinary mediated associations, and occupies an intermediate position in the range of simple to complex brain mechanisms.
