Can APB 2000 Be Used to Discern Sincerity of Effort in Unimpaired Subjects from Maximal Performance in Subjects with Shoulder Pain?

The automated pegboard (APB 2000), which has been found to objectively quantify motor performance, was used to differentiate maximal motor performance among subjects with shoulder pain, healthy unimpaired subjects performing normally and also while feigning shoulder pain. Six participants with shoulder pain and 15 healthy unimpaired individuals participated. Individuals with shoulder pain were tested on the APB 2000 using their affected upper extremity. Unimpaired participants were instructed to perform normally on the test with randomly selected upper extremity and to feign shoulder pain with the other upper extremity. The two tests for the unimpaired participants were conducted 1 week apart. There were significant differences in mean performance time for normal, patient, and feigned performance, with 80, 111, and 149 sec for the three groups respectively (p < 0.0005). There was also considerable overlap in the three distributions of performance times. These preliminary findings suggest that the APB 2000 is able to distinguish performance time between these three groups. Whether it can be used to distinguish between maximal performance and submaximal performance in individuals suspected of submaximal performance requires further study.     

Beyond incubation: an analysis of firm survival and exit dynamics in the post-graduation period

With regard to the survival rates of business incubator (BI) firms, the literature mainly presents findings of failure rates only during the incubation period. Little is known about the survival or exit dynamics of firms after leaving the incubator facilities. This study approaches this research question by examining the survival of 352 firms from five German BIs after their graduation. The findings suggest that graduation causes an immediate negative effect on survivability that lasts up to 3 years after leaving the incubators. Furthermore, heterogeneous patterns of post-graduation exit dynamics between the BIs were observed. It was also found that performance during the incubation period is an indicator of the propensity of business closure after graduation. This study offers valuable insights and implications for all stakeholders of BI-initiatives.      

政府绩效评估制度安排的现实困境及其消解

政府绩效评估制度的本质就是以评估来促进政府行为的规范,加强对政府监督,强化政府的责任,提高政府的效率.然而当下中国,政府绩效评估的制度安排遇到了现实困境:政府绩效评估价值扭曲带来制度安排困境,政府绩效评估客体与主体失衡带来制度安排偏差,绩效评估系统内部运行阻滞带来制度安排障碍.消解政府绩效评估制度安排困境,从价值层面必须考虑社会公平、宽容合作;从运作体系必须考虑目标系统、比较系统、测定系统的制度安排要符合系统之间的逻辑关联.     

论利用影响力受贿罪的客观方面

利用影响力受贿罪是《刑法修正案（七）》增设的犯罪,与我国《刑法》规定的受贿罪有本质区别,与《联合国反腐败公约》中的影响力交易罪存在处罚范围上的差异。利用影响力受贿罪的客观方面包括利用影响力、通过职务行为为请托人谋取不正当利益、索取或者收受财物和数额较大或者有其他较重情节几个构成要素,除了索取或者收受财物这一要素外,其他的要素自有其特殊性。     

论社区警务绩效评估指标体系的构建

开展社区警务绩效评估活动,首先应构建一个合理的评估指标体系,需遵循五项原则,即一致性原则、可测性原则、可比性原则、代表性原则和公众导向性原则。本文在遵循这五项基本原则的基础上,结合社区警务工作实践,构建了一套社区警务绩效评估指标体系,并对各项指标内涵进行了相关说明。     

Enhancing student performance and employability through the use of authentic assessment techniques in extra and co-curricular activities (ECCAs)

The paper advocates the use of authentic assessment techniques, delivered in extra and co-curricular activities (ECCAs), to augment and improve student performance on academic law degree programmes. A combination of formative and summative methods in ECCA assessment provides the optimum environment to measure and improve the crucial critical reasoning skill – the key transferable skill to academic degree success. This skill, when developed in students, is also highly prized by prospective employers, and therefore, the use of authentic assessment improves graduate employability rates.     

Offence characteristics and cognitive functioning in juveniles adjudicated for illegal sexual behaviour

Intelligence differences exist between sex offenders and non-sex offenders in adult populations, but comparable intelligence differences are not consistently found among juveniles. However, juveniles may differ on measures of intelligence across offence-related variables used to subclassify adults. The purpose of the present study was to determine if between- and within-group differences exist in a sample of 925 juveniles adjudicated for illegal sexual and non-sexual behaviours across offence-related variables. The results suggest that juveniles adjudicated for illegal sexual behaviour outperformed juveniles adjudicated for non-sexual offences on Wechsler Abbreviated Scale of Intelligence (WASI) performance, though full-scale intelligence quotients scores for both groups were lower than would be expected in the general population. Unlike adult offenders, juveniles adjudicated for illegal sexual behaviour do not tend to differ on WASI performance across offence-related variables. These results provide additional evidence that these juveniles adjudicated for illegal sexual behaviour are categorically distinct from adults who sexually offend.

Quantitation of Synthetic Cannabinoids in Plant Materials Using High Performance Liquid Chromatography with UV Detection (Validated Method)

Plant based products laced with synthetic cannabinoids have become popular substances of abuse over the last decade. Quantitative analysis for synthetic cannabinoid content in the laced materials is necessary for health hazard assessments addressing overall exposure and toxicity when the products are smoked. A validated, broadly applicable HPLC‐UV method for the determination of synthetic cannabinoids in plant materials is presented, using acetonitrile extraction and separation on a commercial phenylhexyl stationary phase. UV detection provides excellent sensitivity with limits of quantitation (LOQs) less than 10 μg/g for many cannabinoids. The method was validated for several structural classes (dibenzopyrans, cyclohexylphenols, naphthoylindoles, benzoylindoles, phenylacetylindoles, tetramethylcyclopropylindoles) based on spike recovery experiments in multiple plant materials over a wide cannabinoid contents range (0.1–81 mg/g). Average recovery across 32 cannabinoids was 94% for marshmallow leaf, 95% for damiana leaf, and 92% for mullein leaf. The method was applied to a series of case‐related products with determined amounts ranging from 0.2 to >100 mg/g.
