上海地区商品代蛋鸡J亚群禽白血病的病理学观察

对上海地区2个规模化商品蛋鸡场疑似禽白血病病例进行了组织病理学观察和ELISA检测,发现发病鸡群中血管瘤占50%,纤维肉瘤占37.5%,髓细胞瘤占12.5%,J亚群禽白血病的血清抗体阳性率分别达25%和15%。血管瘤主要见于脚部和翅膀,组织病理学观察表明为海绵状血管瘤,纤维肉瘤主要见于肌肉组织内,对弥漫性肝、脾肿大的病例观察表明肿瘤组织为髓细胞瘤。证实该鸡群感染了J亚群禽白血病病毒,并表现为以髓细胞瘤、血管瘤和纤维肉瘤为主的多种肿瘤性传染病。     

PPMs标准研究

环境污染很大程度上是在生产过程中产生的,PPMs标准就是对产品的加工和生产过程所制定的特定的环境标准。PPMs标准作为国际环境保护的一个重要措施,同时又成为影响WTO规则下自由贸易的一种壁垒方式,日益成为国际社会关注的重点。本文在对WTO法规内外PPMs标准研究的基础上,提出了对PPMs标准需客观地看待的观点,并对我国应当采取的法律对策提出粗浅建议。     

Brandom on Norms and Objectivity

The aim of this paper is to investigate Brandom’s conception of the objectivity of norms. In Making It Explicit Brandom supports a weak notion of objectivity based on his understanding of the perspectival structure of linguistic practices. In his following works, he resorts to the Hegelian notion of recognition, adding a historical dimension to his account. I contend that this notion of objectivity can be successfully defended against the objections raised by the commentators. In particular, it does not jeopardise the same possibility of communication, as claimed by Habermas and others, unless a strongly objective notion of communication is assumed. However, the paradigm shift from a strong to a weak understanding of objectivity entails a consequent revision of the conception of social criticism.

Intercepting Disgrace: Lacuna and “Letter to John Coetzee”

ABSTRACT

This review article examines two palimpsest rewritings of J. M.Coetzee’s canonical but controversial novel, Disgrace (1999). Both rewritings are by women: Lacuna, a novel published in 2019, is by a white South African woman, Fiona Snyckers, and “Letter to John Coetzee” takes the form of a short story by Michelle Cahill, a woman of color living in Australia, published in Cahill’s collection Letter to Pessoa (2016). The article uses Cahill’s coinage of “interceptionality” to discuss how dominant narratives may be disrupted and subverted, particularly when it comes to representing gender-based violence in the arts. It concludes with a discussion of South African artist Gabrielle Goliath’s exhibition, “This song is for … ” (2019).     

Y chromosome J2 subtyping in an Italian sample: Population and forensic implications

In the recent years the Y chromosome genealogy has been refined by a number of newly discovered SNPs. The non-random distribution of the Y chromosome lineages worldwide makes fundamental the dissection and characterisation of haplogroups associated with specific geographic areas. In Southern Europe the haplogroup J2, as defined by the M172 marker, can reach frequencies up to 35%, making the dissection of such lineage critical for population studies. Here we present a study on J2 chromosomes from the Italian peninsula. Populations and forensic implications are discussed. A total of 900 individuals were previously genotyped for a number of SNPs, including M172. More than 200 of these have been now genotyped for 7 SNPs within the J2 lineage using a multiplex SNaPshot approach. The different distribution of the various lineages in different geographic areas probably reflects different historical demographic events and points to differential Y chromosome haplotype distribution, with implication for forensic application of this genetic marker.

私利·公利·正义·仁义--义利关系的传统反思与现代诠释

本文首先在剖析中西义利观区别的基础上,把义和利的内涵分别分解为私利、公利和正义、仁义等不同层次.然后通过对社会主义市场经济内在本质的考察,提出理解义利关系的三大理论原则第一,以私利为动力,以公利为目标;第二,以正义为约束,以仁义为引导;第三,以利释义,以义制利,义利统一.最后根据以上原则提出社会主义市场经济条件下坚持义利统一的三个层次合理谋利即是义;增进公利即是义;自觉让利即是义.
