Estimating actual foot size from a static bare foot print in a White British Population

In forensic intelligence-gathering it would be useful to be able to estimate the size of a perpetrator's foot from a standing bare footprint found at the scene of crime. Currently, the advice is to add a fixed amount to the length of the footprint (typically 1.5 or 2.0 cm), but there is little evidence for this approach. This study used measured footprint and actual foot lengths from 146 participants from the white British student population of a University in the UK. Data were analysed using multiple regression with foot length as the dependent (outcome) variable and footprint length and sex as the independent variable/factor respectively. Sex was not a significant predictor. The regression equation for the best estimate of the foot length is 19.89 + 0.95 × print length ± 8 mm.     

大治安及其学说之边际

大治安,既是个含超公安管理的话题,又是个含超社会治安的话题,还是个含超安邦定国的话题。天时、地利、人和集一身,大治安及其学说必须厘清边际。大治安及其学说边际之长,指大治安是全过程的治安,涉及治安之前、中、后全过程。大治安及其学说边际之宽,指大治安是全方位的治安,涉及治安之官、民、匪全方位。大治安及其学说边际之高,指大治安是全层次的治安,涉及治安之社（社会）、人（人文）、物（自然）全层次。     

Ten methods for calculating the uncertainty of measurement

While forensic laboratories are coming under increasing pressure to provide meaningful estimates of measurement uncertainty, there has been little discussion of this topic in the literature. This article summarizes ten bases for estimating this parameter: (1) proficiency tests; (2) readability limits; (3) independent reference materials; (4) operational limits applied during calibration; (5) expert judgment; (6) precision control samples without (6) and with (7) contributions from extramural sources of error; (8) error budgets; (9) historical performance; and (10) ruggedness tests. Based on the assumptions underlying each approach, the forensic community will need to apply a variety of discipline-specific approaches to arrive at satisfactory estimates of measurement uncertainty.     

Predictors of length of stay in forensic psychiatry: The influence of perceived risk of violence

This study describes the prevalence of adverse events and length of stay in forensic psychiatric patients with and without a restriction order. Detailed clinical and administrative information from medical records and written court decisions was gathered retrospectively from admission until discharge for a Swedish population-based, consecutive cohort of forensic psychiatric patients (n = 125). The median length of stay for the whole cohort was 951 days, but patients with a restriction order stayed in hospital almost five times as long as patients without. Restriction orders were related to convictions for violent crime, but not for any other differences in demographic or clinical variables. The majority of the patients (60%) were involved in adverse events (violence, threats, substance abuse, or absconding) at some time during their treatment. Patients with restriction orders were overrepresented in violent and threat events. Previous contact with child and adolescence psychiatric services, current violent index crime, psychotic disorders, a history of substance, and absconding during treatment predicted longer length of stay. Being a parent, high current Global Assessment of Functioning scores, and mood disorders were all significantly related to earlier discharge. In a stepwise Cox regression analysis current violent index crime and absconding remained risk factors for a longer hospital stay, while a diagnosis of mood disorder was significantly related to a shorter length of stay.     

Patient characteristics related to length of stay in Dutch forensic psychiatric care

Create an overview of characteristics of patients in long-term forensic psychiatric care (LFPC) with a higher length of stay (LOS) care compared to patients in regular forensic psychiatric care (RFPC) with a shorter LOS. Data were collected from 139 patient records. This study examined whether patients in LFPC differ from patients in RFPC on sociodemographic data, legal data and clinical data and whether those characteristics are able to predict LOS. Patients in LFPC were more often born in a Dutch Caribbean country, less often had a substance abuse disorder, were more often emotionally neglected during childhood, had a higher HCR-20 risk item score, a higher security needs score, a higher (less successful) recovery score, were more often recidivist and had absconded more often than RFPC patients. Certain characteristics were able to distinguish the longer LOS group which might be useful to establish sequel services and enhance treatment efficiency.     

中国人p33.6位点的扩增片段长度多态性

用PCR、小型聚丙烯酰胺凝胶电泳和银染法对小卫星区域p33.6(D1S111)位点的扩增片段长度多态性(Amp—FLP)进行分析和对100例无关中国人p33.6位点的等位基因频率进行调查及数据处理,发现该位点核心序列重复数从9到22之间的全部14个等位基因,片段长度分布于435～925bp之间,基因频率为0.5～35.5％,杂合度为76％。对6个家系共22名相关个体进行分析,符合孟德尔遗传定律;对人体各种不同组织DNA进行该位点的分析,显示出高度的一致性。该位点适用于法医学上的个人识别以及亲子鉴定。     

DNA的apoB位点扩增片段长度多态性的检测及其在法医学中的应用

用PCR方法对100例无关个体血样的apoB位点扩增片段进行研究,已发现有11个等位基因,片段长度分布于600～1100bp之间,基因频率为0.005～0.525,杂合度为70％。家系分析及对人体血液、血斑、精液、精斑、混合斑、带毛囊毛发及其它各种有核细胞组织的研究表明,该技术在个人识别及亲子鉴定上均能发挥重要作用。     

山东半岛地区大学生手长足长与身高关系的研究

对山东半岛地区1000名汉族大学生的手长、足长和身高进行活体测量。经统计学处理，求出由手长、足长与身高相互推算的回归方程式。相关系数为0．51～0．66，其中男性高于女性。由手长推算身高的回归方程式较由足长推算身高的回归方程式，有较高的相关系数和较低的标准估计误差。
