上市公司股权再融资偏好的自由现金流量解释

上市公司应避免采用股权再融资方式筹集资金,以减少对公司价值产生的负面影响。但国内外仍有不少上市公司采用股权再融资,我国则呈现强烈的股权再融资偏好,这说明上市公司采用股权再融资存在一定的理论依据。现实中上市公司管理者在公司股份中只占有很少的比例,因此上市公司管理者更注重非货币利益的获取。为了获取更多的非货币利益,他们更倾向于采用股权再融资。而我国不太合理的制度背景,使得我国上市公司管理者几乎不拥有公司股份,从而造成我国上市公司强烈的股权再融资偏好。     

尸体甲状腺球蛋白降解及其与死亡时间的关系

目的探讨尸体甲状腺球蛋白降解程度与死亡时间(PM I)的关系。方法死后21d内尸体的甲状腺组织,经免疫组化(EPOS)法染色,观察甲状腺球蛋白的染色反应;对63例阳性染色的甲状腺组织(PM I≤5d)进行计算机图像分析,并对所得图像参数的数据进行统计学分析。结果PM I≤5d的甲状腺组织,甲状腺腺泡上皮细胞胞浆及甲状腺胶质中均显示了不同程度的免疫反应阳性;PM I超过12d,免疫反应阴性;经图像分析及统计学处理,其积分光密度、分布密度和目标面积与PM I之间的确定系数(R2)分别达0.9794,0.9732及0.9884。结论尸体甲状腺组织的甲状腺球蛋白降解程度随PM I不同而变化,二者呈现较强的相关性。     

The Curious Incident of Mr Cameron and the United Kingdom Defence Budget: A New Legacy?

During 2015 Prime Minister Cameron found himself under intense domestic and international pressure over his apparent reluctance to maintain United Kingdom defence spending at the NATO target level of 2 per cent of GDP. Most commentators attributed this reluctance to the inevitability of defence cuts if the government wished to meet its deficit reduction targets. However, the aftermath of the general election saw a sudden decision to maintain UK defence spending at the NATO target level. This u‐turn is one of the more curious episodes in recent British defence policy. In this article we explore the reasons why, at a time of continuing cuts and austerity measures and against all the political signals, a decision was made to meet the 2 per cent target, and what this means for the UK's defence policy. In doing so, we analyse why most commentators assumed that defence cuts were inevitable, the domestic and international factors that explain the government's apparent u‐turn and what this revised defence budget settlement meant for the new 2015 National Security Strategy and Strategic Defence and Security Review.     

The domestic politics of international development in South Korea: stakeholders and competing policy discourses

Abstract

The paper examines the domestic politics surrounding South Korea's foreign aid policy. It delineates the institutional characteristics and strategic interests of key government and non-government stakeholders, and suggests an analytical framework to comprehend the country's aid policy regime. It suggests that two competing policy discourses exist – one emphasising ‘intellectual leadership’ and the other ‘ethical leadership’ as the key principle of aid policy. In practice, the country's political leadership promulgates a complex amalgam of these discourses in alignment with their own political imperatives and interests. The paper discusses ‘Global Saemaul Undong’ as such an example under the incumbent Park Geun-Hye administration.     

CT、MRI在弥漫性轴索损伤法医学鉴定中应用价值分析

目的探讨CT和MRI检查方法在弥漫性轴索损伤(diffuse axonal injury,DAI)法医学鉴定中的应用价值。方法收集26例CT和MRI影像资料齐全的DAI鉴定资料进行回顾性分析,比较CT和MRI两种方法对DAI病灶检出率的差异,分析DAI病灶检出数量与法医学鉴定结果之间的关系。结果 26例经MRI检出DAI病灶787个,经CT检出DAI病灶32个,MRI对DAI病灶的敏感度显著高于CT(P0.01)具有统计学意义。26例DAI鉴定的伤残等级数值与影像学检查发现的病灶数量之间存在负相关(r=-0.908,P0.01)。结论 MRI检查对DAI病灶的检出率较CT检查具有明显优势,可为DAI诊断提供更为准确的依据,在法医临床学鉴定中具有重要的应用价值。     

Severe personality disorder,treatment engagement and the Legal Aid,Sentencing and Punishment of Offenders Act 2012: what you need to know

Empirical research has demonstrated a link between legal coercion and treatment engagement following conviction among those with severe personality disorder. Legal coercive pressures were often applied by the Indeterminate Sentence for Public Protection (IPP), until it was replaced by the Extended Determinate Sentence by the Legal Aid, Sentencing and Punishment of Offenders Act 2012. In this paper, it is proposed that use of the new determinate sentence will lessen motivation for treatment engagement. One effect of treatment refusal may be greater reliance by the Secretary of State for Justice on his jurisdiction to transfer prisoners due for release to secure hospital transfers under the Mental Health Act 1983. Not only will this risk posturing undermine the principal aim of the Offender Personality Disorder Implementation Pathway to improve treatment engagement among the target group, it will also have negative implications for medical practitioners working in secure forensic hospitals. To demonstrate what is at stake, the paper briefly recapitulates empirical findings familiar to readers of the journal, before drawing on original unpublished data.     

运用二代测序技术拆分混合STR分型

目的探讨二代测序技术在混合STR分型拆分中的应用。方法对一例强制猥亵妇女案中受害人颈部的拭子和血样作DNA提取,以Precision ID GlobalFiler^TM NGS STR Panel v2试剂盒制备文库,经Ion S5测序仪测序,运用Torrent_Suite_v5.2.1软件进行数据分析后,将检测基因座的序列多态STR分型与长度多态STR分型进行比较。结果在D8S1179、D21S11、D2S441、D2S1338、D10S1248五个基因座发现存在序列特异的等位基因亚型,利用这些亚型对混合STR分型进行了成功拆分。结论二代测序技术提供的等位基因序列信息可对混合STR分型的拆分起到帮助作用。     

Analysis of some commonly found inhalants using gas chromatography-mass spectrometry (GC MS) – Effect of substrates on the identification of inhalants

Inhalant abuse is a serious and ever-evolving problem for our society. Inhalants are abused more commonly by teenagers and adolescents. Inhalants such as glue, paint thinners, correction fluid, and nail paint remover are easily available in the market which makes them readily abused. Out of various methods of abuse, huffing (placing a piece of cloth soaked with inhalant is placed in the mouth), bagging (placing head in a polythene bag containing inhalant), and ballooning (balloons filled with inhalant are used for inhaling vapors through the mouth) are most common. Inhalant abuse results in multiple target organ dysfunction with neuritis and brain damage due to the dissolution of the myelin sheath. In acute poisoning cases, it might cause death due to asphyxia and sudden sniffing syndrome. In such cases, various articles containing traces of inhalants could be retrieved from the scene of incidence and to detect these traces become an important facet of the investigation. However, it might be difficult due to the rapid evaporation of inhalants and the formation of reaction product species. In the present study, an attempt has been made to study the effect of three substrates (balloon, cloth, polythene) on component profiles of four paint thinners and four nail paint removers. The study suggests that although some components are retained, there is the formation of a large number of reaction product species and these must be taken into consideration before furnishing the opinion. These reaction product species might also be inhalant specific which must be further explored.     

This May Come As a Surprise: How Prior Knowledge of Information in a Fear Appeal is Associated with Message Outcomes

Two related studies were performed aimed at finding if and how prior knowledge of threat and efficacy information in a fear appeal message is associated with message outcomes (attitude and behavioural intentions). the extended Parallel Process model (ePPm) (Witte 1992; 1998) served as theoretical framework for one study about a chlamydia fear appeal (n = 57) and another about an alcohol abuse fear appeal (n = 59). Findings from both studies suggest that prior knowledge of threat information is hardly relevant for readers’ reactions to a fear appeal message. Prior knowledge of efficacy information, however, proved to play a more important role, most often in a positive way. Findings from both studies furthermore suggest that the ePPm may be incorrect in assuming that individual differences – in this case, in prior knowledge – may only affect fear appeal outcomes in an indirect way, that is through different perceptions of threat and efficacy.
