Trust that binds: The impact of collective felt trust on organizational performance.

The impact of employees' collective perceptions of being trusted by management was examined with a longitudinal study involving 88 retail stores. Drawing on the appropriateness framework (March, 1994; Weber, Kopelman, & Messick, 2004), the authors develop and test a model showing that when employees in an organization perceive they are trusted by management, increases in the presence of responsibility norms, as well as in the sales performance and customer service performance of the organization, are observed. Moreover, the relationship between perceptions of being trusted and sales performance is fully mediated by responsibility norms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Autosomal Dominant Gyrate Atrophy-Like Choroidal Dystrophy Revisited: 45 Years Follow-Up and Association with a Novel C1QTNF5 Missense Variant

We present a long-term follow-up in autosomal dominant gyrate atrophy-like choroidal dystrophy (adGALCD) and propose a possible genotype/phenotype correlation. Ophthalmic examination of six patients from two families revealed confluent areas of choroidal atrophy resembling gyrate atrophy, starting in the second decade of life. Progression continued centrally, reaching the fovea at about 60 years of age. Subretinal deposits, retinal pigmentation or choroidal neovascularization as seen in late-onset retinal degeneration (LORD) were not observed. Whole genome sequencing revealed a novel missense variant in the C1QTNF5 gene (p.(Q180E)) which was found in heterozygous state in all affected subjects. Haplotype analysis showed that this variant found in both families is identical by descent. Three-dimensional modeling of the possible supramolecular assemblies of C1QTNF5 revealed that the p.(Q180E) variant led to the destabilization of protein tertiary and quaternary structures, affecting both the stability of the single protomer and the entire globular head, thus exerting detrimental effects on the formation of C1QTNF5 trimeric globular domains and their interaction. In conclusion, we propose that the p.(Q180E) variant causes a specific phenotype, adGALCD, that differs in multiple clinical aspects from LORD. Disruption of optimal cell-adhesion mechanisms is expected when analyzing the effects of the point mutation at the protein level.     

基于储层静态地质参数的一种随机建模结果排序方法

储层随机建模可以产生大量实现,而油藏数值模拟由于计算量大,通常只能对非常有限的实现进行模拟计算。随机选择实现常常会导致过于悲观或过于乐观的模拟结果,并且无法合理评价地质模型所包含的不确定性。利用与数模响应密切相关的静态地质指标,如连通原油体积对实现进行排序,然后选择典型的实现进行数模,较好地解决这一问题。但是,该指标没有考虑含油网格与生产井之间的距离及渗透率大小,而这两个参数对于流体流动有着重要的控制作用。在连通原油体积的基础上提出了一种新的排序指标。该指标在计算连通原油体积的公式上增加了网格与生产井之间的距离和渗透率两个影响因子。通过实例对这两种指标进行了对比研究,新指标更好地反映了不同实现的差别。     

Two-color antibunching from band-gap engineered colloidal semiconductor nanocrystals

Photon antibunching is ubiquitously observed in light emitted from quantum systems but is usually associated only with the lowest excited state of the emitter. Here, we devise a fluorophore that upon photoexcitation emits in either one of two distinct colors but exhibits strong antibunching between the two. This work demonstrates the possibility of creating room-temperature quantum emitters with higher complexity than effective two level systems via colloidal synthesis.     

Roles of ephrinB ligands and EphB receptors in cardiovascular development: demarcation of arterial/venous domains, vascular morphogenesis, and sprouting angiogenesis

Both triploids and gynogenetic diploids (GDs) were produced to clarify the relationship between the sex-chromosome constitution and the expression of sex in the common bell-ring frog, Buergeria buergeri. The sex differentiation of triploids in B. buergeri is quite remarkable. Triploid frogs consisted of three sex genotypes, ZZZ, ZWW and ZZW. All ZZZ triploids were males, and all ZWW triploids were females. It is very interesting that half of the ZZW triploids became female, and the other half became male. The GD frogs consisted of two sex genotypes, ZW and ZZ, which did not differ from the controls in sex differentiation. Since the ratios of ZZ and ZW eggs were significantly different among female parents, it is assumed that most (approximately 80-90%) of the eggs made pre-reductional division in some females and post-reductional division in others during meiosis. It seems that ZW eggs were produced by the occurrence of recombination between the centromere and the sex-determining genes in B. buergeri. It was also found that the number of Z chromosomes in each cell of these triploids and GDs agreed with that of the nucleoli in each cell.     

Recommendations for mass spectrometry data quality metrics for open access data (corollary to the Amsterdam principles)

Policies supporting the rapid and open sharing of proteomic data are being implemented by the leading journals in the field. The proteomics community is taking steps to ensure that data are made publicly accessible and are of high quality, a challenging task that requires the development and deployment of methods for measuring and documenting data quality metrics. On September 18, 2010, the U.S. National Cancer Institute (NCI) convened the "International Workshop on Proteomic Data Quality Metrics" in Sydney, Australia, to identify and address issues facing the development and use of such methods for open access proteomics data. The stakeholders at the workshop enumerated the key principles underlying a framework for data quality assessment in mass spectrometry data that will meet the needs of the research community, journals, funding agencies, and data repositories. Attendees discussed and agreed up on two primary needs for the wide use of quality metrics: (i) an evolving list of comprehensive quality metrics and (ii) standards accompanied by software analytics. Attendees stressed the importance of increased education and training programs to promote reliable protocols in proteomics. This workshop report explores the historic precedents, key discussions, and necessary next steps to enhance the quality of open access data. By agreement, this article is published simultaneously in Proteomics, Proteomics Clinical Applications, Journal of Proteome Research, and Molecular and Cellular Proteomics, as a public service to the research community. The peer review process was a coordinated effort conducted by a panel of referees selected by the journals.     

Prolonging Shelf-Life of Carp by Combined Ionising Radiation and Refrigeration

Experiments were performed using ionisating radiation in order to prolong the shelf-life of two groups of refrigerated fish ( Cyprinus carpio ). After irradiation fish were kept at 0–2°C. Non-irradiated fish reached the non-acceptability point in 16 days and irradiated fish reached that point in 31 days. No difference was found between shelf-life of whole or eviscerated fish. If fish were immediately cooled to 0°C after death, their shelf-life was prolonged considerably. From this study it is clear that chemical tests of freshness such as TVB-N and K value determination are not appropriate for the study of irradiated fish. Organoleptic estimations and a new determination using an odour concentration meter seem to fit best the objective determination of freshness.     

Reliability and construct validity of the Paired-Associate Recognition Test: A test of declarative memory using Wisconsin Card Sorting stimuli.

The Paired-Associate Recognition Test (PART) was developed to test declarative memory using Wisconsin Card Sorting Test (WCST) stimuli, for use in physiologic neuroimaging studies of memory and executive function in schizophrenia. PART was administered to 55 healthy adults (30 male, 25 female) to establish reliability and construct validity. Reliability results indicate that PART performance was stable across trials and internally consistent. Convergent validity was confirmed by significant correlations between PART and standard measures of visual recall, and by PART loading on a memory factor. Divergent validity was established through low correlations between PART and WCST, and by a loading of WCST on a separate factor. Overall results indicate that PART can be administered reliably and that it requires declarative memory processes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
