Forensic Entomology and the Estimation of the Minimum Time Since Death in Indoor Cases

Eight cases that occurred indoors in which the insects played an important role in the mPMI estimation are presented. The bodies of socially isolated people and old people living alone were discovered in central Italy between June and November. mPMI ranged from a few days to several weeks. Insects were collected during the body recovery and the postmortem. Climatic data were obtained from the closest meteorological stations and from measurements performed on the site. Sarcophagidae and Calliphoridae species were present in 75% of the cases with Lucilia sericata and Chrysomya albiceps collected in 50% of the cases. Chrysomya albiceps was always found in association with Lucilia species. Scuttle flies (Phoridae) were found in 37.5% of the cases, confirming the ability of these species in indoor body colonization. We show that if sealed environment may delay, the insect arrival dirty houses may create the environment where sarcosaprophagous insects are already present.     

背部推拿疗法对免疫抑制家兔局部皮肤CD80、波形蛋白表达的影响

目的观察在免疫抑制家兔背部足太阳膀胱经循行路线上开展推拿疗法对局部皮肤CD80、波形蛋白表达的影响。方法将18只家兔随机平均分为空白组、模型组和推拿组,采用腹腔注射环磷酰胺的方法造模,观察各组动物局部皮肤CD80、波形蛋白表达的变化。结果模型组CD80、波形蛋白的表达(阳性细胞数、表达强度)均低于空白组(P<0.05,P<0.01);推拿组CD80、波形蛋白的表达(阳性细胞数、表达强度)均高于模型组(P<0.05,P<0.01)。结论采用腹腔注射环磷酰胺的方法能够制造免疫抑制动物模型;在足太阳膀胱经循行路线上开展背部推拿疗法能够有效促进局部皮肤CD80、波形蛋白的表达,从而调节免疫抑制家兔的局部免疫功能。     

中国死刑的未来发展方向

Curbing Corruption in Public Administration: A Case Study from Italy

The aim of this article is to verify whether the historic sentence, no. 500/1999 of the Italian Legitimacy Court (Corte di Cassazione) in Plenary Session, may have contributed to diminishing bribery in Italy, by increasing the area of liability for both civil servants and the public administration. The empirical analysis is based on a case study conducted in Sicily, in the province of Catania, using a unique data set. The main results of the article are: paying bureaucrats by means of an incentive wage regimes may not be effective in reducing corruption; an extension of the liability rule for the public administration and civil servants may discourage the phenomenon of bribery; and, the perfect specification of property rights helps to reduce corruption.     

How Much Is Really Known About the Meaning of the Term “Conflict of Interest”?

Often codes of ethics require dealing with conflict of interest (CoI) without defining the boundaries of the phenomenon. In this case, CoI recognition is left to the discretion of the individual. The aim of this work is to answer to the following research questions: How much is really known about the meaning of the term CoI? Do individuals share the same CoI definition? In order to address these questions, we use the results of a questionnaire administered to 86 Italian public sector employees during some training courses on conflict of interest and corruption. The choice of this sample is particularly significant in that the Italian regulation provides for all public employees a code of conduct that requests avoiding, or at least disclosing, the CoI without prior definition of the meaning of the term. The results of our analysis show that public employees are uncertain about or come to different considerations of what CoI is and is not; consequently they deal with it in different ways. Thus, codes of conduct and ethics trainers should direct more attention on CoI definition, providing examples to facilitate its identification and resolution.     

Contractual Conditions,Organizational Level,Dimension of Organization,and Work Conflict as Potential Predictors of Job Stress in Public Administration

Job stress is a pervasive problem for employers in the 21st century economy, making it a timely and important topic in organizational settings. The variables influencing job stress are numerous and consequently it may be analyzed from different perspectives, but the root is primarily physical and psychosocial. This study specifically explores three physical sources of job stress—contractual condition of work, organizational position, and dimension of organization—and of one psychosocial source—work conflict. A survey instrument was used to collect information from regional Public Administration employees of South Italy. Data from 1,130 respondents were analyzed. Statistical correlations and hierarchical regression showed that contractual condition of work, organizational position, organizational dimension, and work conflict were all predictive aspects of job stress.     

Microwave Selective Thermal Development of Latent Fingerprints on Porous Surfaces: Potentialities of the Method and Preliminary Experimental Results

The thermal development of latent fingerprints on paper surfaces is a simple, safe, and chemicals‐free method, based on the faster heating of the substrate underlying the print residue. Microwave heating is proposed for the first time for the development of latent fingerprints on cellulose‐based substrate, in order to add to the thermal development mechanism the further characteristic of being able to heat the fingerprint residues to a different extent with respect to the substrate, due to the intrinsic difference in their dielectric properties. Numerical simulation was performed to confirm and highlight the selectivity of microwaves, and preliminary experimental results point out the great potentialities of this technique, which allowed developing both latent sebaceous‐rich and latent eccrine‐rich fingerprints on different porous surfaces, in less than 30 sec time with an applied output power of 500 W. Microwaves demonstrated more effectiveness in the development of eccrine‐rich residues, aged up to 12 weeks.     

GC/MS、GC/NPD法检测毛发中的氯胺酮

目的采用液-液萃取、衍生化和GC/MS、GC/NPD方法,进行毛发中氯胺酮定性定量分析。方法选择4-苯基丁胺为内标,毛发样本用NaOH、HCl及芳基硫酸酯酶/β-葡萄糖醛酸酶等3种方式进行水解,再进行衍生化后,采用GC/MS和GC/NPD方法定性定量分析。对不同水解和衍生化条件以及提取溶剂进行比较优化,并考察方法精密度、稳定性和检出限。结果方法的提取回收率大于95%,精密度和样品稳定性良好,日内和日间标准偏差小于6%;采用GC/NPD和GC/MS直接分析毛发中的氯胺酮,检出限为0.2ng/mg和2.0ng/mg,线性范围为10.0～250.0ng/mg,相关系数均大于0.99;采用酰化衍生化后分析,GC/NPD和GC/MS检出限分别提高至0.1ng/mg和0.2ng/mg。结论该方法回收率高、检测限低,可以用于毛发中氯胺酮的定性定量分析检验。
