Markov chain Monte Carlo methods for high dimensional inversion in remote sensing

Summary.  We discuss the inversion of the gas profiles (ozone, NO₃, NO₂, aerosols and neutral density) in the upper atmosphere from the spectral occultation measurements. The data are produced by the 'Global ozone monitoring of occultation of stars' instrument on board the Envisat satellite that was launched in March 2002. The instrument measures the attenuation of light spectra at various horizontal paths from about 100 km down to 10–20 km. The new feature is that these data allow the inversion of the gas concentration height profiles. A short introduction is given to the present operational data management procedure with examples of the first real data inversion. Several solution options for a more comprehensive statistical inversion are presented. A direct inversion leads to a non-linear model with hundreds of parameters to be estimated. The problem is solved with an adaptive single-step Markov chain Monte Carlo algorithm. Another approach is to divide the problem into several non-linear smaller dimensional problems, to run parallel adaptive Markov chain Monte Carlo chains for them and to solve the gas profiles in repetitive linear steps. The effect of grid size is discussed, and we present how the prior regularization takes the grid size into account in a way that effectively leads to a grid-independent inversion.

转移价格在跨国公司中的作用及其限制——揭开跨国公司巧取豪夺的面纱

转移价格是跨国公司在母公司与子公司、子公司与子公司之间进行内部贸易所采用的价格 ,是人为调高或调低价格来转移利润而采取的重要手段 ,使子公司经营处于“亏损”状态 ,从而使东道国蒙受巨大经济损失。为此 ,各东道国为维护本国的合法权益而采取多种防范和监控措施来限制跨国公司用转移价格来实现其整体总利润额的增加。     

Factors Affecting Children’s Adjustment to the Death of a Parent: The Social Work Professional’s Viewpoint

This study investigated factors affecting the adjustment of parentally bereaved children by reviewing existing literature and comparing it to observations made by professional social workers. Interviewees had between 1 1/2 and 22 years of experience in counseling bereaved children. The specific factors examined were age and sex of the bereaved child, circumstances of the death, and adjustment of remaining caregiver. Participants (n = 5) responded to an interview instrument specifically designed for this study which contained seven in-depth, open-ended questions. Participants’ replies were mostly in accordance with the literature, but also generated some new perspectives that had not been previously considered for this study and had not appeared in the literature. This study has implications for practice with parentally bereaved children and their surviving caregivers.Rebecca M.

The relationship between paid work and parenthood--a comparison of structures,concepts and developments in the UK and Austria

This article investigates and compares the dominant concepts of public policy concerning the employment-parenthood interface in the UK and Austria. These two countries have been chosen because they represent very different public policy conceptions, particularly in approaching the work-family issue. In order to show the consequences of these policies the paper focuses on working time and time away from employment, when children are very young, and relates these aspects to currently introduced and changed regulatory structures, such as working time regulations and statutory parental leave. The active labour market and family policy in Austria, generally, supports the reconciliation of employment and parenthood. However, the Austrian work-family 'system' suffers from the underlying notion of the male breadwinner model in public support structures and low normative support of employed mothers. The cultural barriers for a more equal distribution of the burdens of combining employment and parenthood seem to be lower in the UK. The market as the political focus, in general, allows more equal opportunities for (qualified) women in the labour market and within families. But the highly flexible and polarised labour market, passive public policy and weak legal protection of employed parents creates a difficult relationship between paid work and family life for many parents, in particular for low-skilled, low-paid parents, above all mothers. These analyses provide the basis for conclusions for public policy aiming at the reconciliation of paid work and parenthood. Ce texte cherche à comparer les concepts dominants de la politique gouvernementale concernant l'interface travail-parent en Grande-Bretagne et en Autriche. Ces deux pays ont été choisis parce qu'ils présentent des concepts de politique gouvernementale très différents, en particulier en ce qui concerne la question de la famille et le travail. Ce texte montre les conséquences de la pratique de ces politiques sur le temps au travail rémunéréet le temps passé à l'extérieur de l'emploi ou sans emploi, et ce, dans un contexte o[ugrave] les enfants sont jeunes. Le texte fait la relation entre ces éléments et la pratique des structures de contrôle existantes et modifiées telles que les lois (ou: les règlements) sur le temps passéau travail et sur les congé parentaux. En général, le marché du travail et la politique de la famille en Autriche encourage la conciliation entre l'emploi et la responsabilité de parent. Par contre, ce système de travail- famille autrichien est un concept qui est fondé à la fois sur le modèle de l'homme comme fournisseur principal du revenu familial dans les structures de soutien public ainsi que sur normes de soutien peu élevées pour les mères employées. Les barrières culturelles face àune distribution plus égalitaire de la responsabilité travail-famille semblent être moins élevées en Grande-Bretagne. En général, le marché et la politique du marché du travail ont offerts plus d'opportunités aux femmes qualifiées. Mais la volatilité (et la polarisation) du marché du travail, la politique gouvernementale passive et la faible protection légale pour les parentstravailleurs créent tous une relation difficile pour les parents entre le travail rémunéré et la vie de famille--en particulier pour ceux qui sont moins qualifiés et mal rémunérés, dont surtout les mères de famille. Cette analyse nous guide vers la nécessité d'une politique gouvernementale qui vise la conciliation entre le travail rémunéré et la responsabilité parentale.     

从战略高度切实加强对领导干部的主动监督

本文主要观点是:建立选拔任用干部的监督机制是我国目前亟需解决的重要问题,它关系到是否能将有中国特色的社会主义事业不断推向前关键不是出了问题以后的解决方法,而是要加强对干部的主动监督,防止干部腐败变质.千秋大业在于用人,在选拔干部时应遵循已制定的科学规范,并从几方面加强监督,在工作中不断完善监督机制,同时要强调对干部的教育培训,并将其作为实施监督的基础性工作.
