目的探讨mtDNA-HVI和Cyt b片段复合扩增法鉴定人与动物混合血痕种属的应用价值。方法用chelex-100法从人、牛、猪、狗、兔、鱼、鸡和鼠血痕中提取DNA,复合扩增mtDNA-HVI片段和Cyt b片段,琼脂糖凝胶电泳检测。结果人类在mtDNA-HVI区和Cyt b区分别出现279bp和358bp各一条带,且279bp条带亮于358bp;动物均只有358bp一条带。人与7种动物血痕的检测灵敏度均为3.13ng。检测人与动物混合DNA,灵敏度仍为3.13ng,但358bp条带亮于279bp条带。结论当358bp带明显强于279bp带时,提示检材为人与动物的混合。 相似文献

Rural industries in West Bengal are characterized by a multiplicity of organizational forms, such as independent petty production, petty production under subcontracting relations with a master trader, modern small‐scale production, and medium‐sized capitalist production. On the basis of field data, we have estimated the amount of surplus generated by these different kinds of producer across a number of organizations and industries, using an alternative criterion: imputing wages to family labour. It was observed that a large number of petty producers generate negative or very low surpluses, and thus have to find supplementary sources of income. Further, the surpluses generated by petty producers attached to a master trader are generally higher than those of independent petty producers.This can be explained in one of two ways. Either the existence of mutual trust between attached petty producers and a master trader offers the former certain advantages over the independent ones, in terms of steady access to urban markets, cheaper sources of raw materials, and easy credit. Or, alternatively, the control such attachment licenses enables a master trader both to extract and to maintain continuous access to higher levels of surplus. For these reasons, this system, of organization lends viability to artisanal production. 相似文献

欧盟有关商标的最重要立法是“协调成员国商标法的1998年12月共同体理事会第一号指令”(以下简称一号指令)和“关于共同体商标的1993年12月20日理事会条例”(以下简称共同体商标条例)。除此之外,还有若干程序性的立法和指南。欧盟商标法上与混淆有关的规定分为三种情形:一是商标及其覆盖的产品或服务均相同;二是商标相同或近似,其所覆盖的产品或服务也相同或类似;三是商标相同或近似,但其覆盖的产品或服务不类似。在上述三种情况下,在先商标都会受到保护,但保护的程度和条件不同。从严格意义上说,上述三种情形中只有第二种与混淆有关。因此,… 相似文献

This study utilizes data for the period 2006–2015 to estimate the determinants of road fatality rates in the Indian states. We employ baseline regression, where the total traffic fatalities, total traffic injuries, rural road fatalities, and urban road fatalities are the functions of human errors in driving, weather conditions, and some control variables. This paper is exclusively focussed upon different sets of human‐driven factors in influencing the road fatality across the Indian states. Our empirical results show that reckless driving, defective motor conditions, bad weather, and reckless driving by bus, truck, and car drivers are found to cause road accidents. We further find that the increase in motorization rates and rash driving are the primary causes behind the road fatalities, and bad weather play a major role in causing road fatalities and injuries in urban areas. However, road fatalities are increasing; still, cases of under reporting, lack of proper road safety regulation, improper investigation procedures, increasing vehicle usages, and higher urbanization have made the matters quite worse in India. 相似文献

A plethora of literature has been undertaken to study the validity of the Feldstein–Horioka (FH) puzzle. However, divergent views continue to persist in the FH puzzle literature. This study explores the empirical validity of the FH puzzle in the case of South Asian countries using annual data from 1960 to 2017. Both panel data approach and Markov‐switching regression approach are used to empirically analyze the FH puzzle. The results of the cointegration test confirm the long‐run relationships between saving and investment in the selected South Asian countries. The results of Markov‐switching regression confirm that the saving‐retention coefficient has shifted from high to low values and also from low to high values. Thus, the FH puzzle exists for a particular time period and mostly depends on the regime shifts in the South Asian countries. The results of panel fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) methods also confirm that FH puzzle holds for the South Asian countries. Therefore, the study suggests that any saving promotion policies are desirable for enhancing investment among the South Asian regions. 相似文献

The Madhya Pradesh Housing & Infrastructure Development Board (MPHIDB) is a state‐owned entity in Madhya Pradesh State of India with the mandate of providing housing for citizens, particularly for those in the low‐income segment. MPHIDB has been constructing houses on its own using the traditional engineering and procurement contract (EPC) model. In July 2015, it was exploring the possibility of creating affordable housing units via public–private partnership (PPP). The advantage of involving private sector is that MPHIDB can tap into creative energy and construction efficiency of the private sector and deliver the best results within the given set of time and resource constraints. The proposed structure of PPP is that the private partner will be given a portion of land in lieu of the affordable housing units that it will build and transfer to MPHIDB. However, there are trade‐offs involved in doing the project in PPP mode instead of EPC mode. The main advantages of a government body like MPHDIB doing the project on its own are as follows: (a) It is able to better manage regulatory risks in terms of getting clearances, land acquisition, and so forth; (b) it can raise finances at lower interest rates than what is charged for private sector entities; and (c) the entire land parcel is available to construct houses, and hence it can get more housing units per unit of land. The Commissioner (CEO) of MPHIDB had to decide whether to go for PPP or EPC model, and if he opted for PPP, how should the PPP be structured? 相似文献

Great changes are underway in how climate and agricultural risks are managed in Vietnam. Uncertainties are emerging regarding the role of the state in managing these risks and what this implies for assumptions regarding hoped-for climate change transformations. Local government control is waning in relation to the expanding roles of the private sector and the growing autonomy of farmers themselves. This article presents cases that illustrate the ways that farmers, private investors, and local authorities are responding to climate risk within roles relating to the other risks involving markets, food security, and pressures on common property resources. 相似文献
