Within the court arena, the credibility and competency of child witnesses often comes under scrutiny and the decision whether a child is considered to be credible or not strongly in?uences whether their evidence will be heard by the court. A child's ability to demonstrate that they understand the difference between truth and lies and the importance of telling the truth is synonymous with competency. Research suggests that many professionals undertaking the task of establishing competency ?nd it very dif?cult, especially with younger children (Aldridge and Wood, 1997, cited in Aldridge and Wood, 1998). This paper describes the process involved in developing an innovative tool for helping professionals assess whether a child understands the difference between truth and lies. The development of the tool arose from the concerns of of?cers from Northumbria Police Force (in the UK) relating to interviews following the protocol of the government's Memorandum of Good Practice (Home Of?ce and Department of Health, 1992) on interviewing child witnesses, and the need to establish whether child witnesses can differentiate between truth and lies. As an example of good practice, The Truth and Lie Story described here has now been included in the Home Of?ce (2002) guidance Achieving Best Evidence in Criminal Proceedings, which is a revision of the 1992 Memorandum of Good Practice.

Marital relationships, like individuals, follow a developmental trajectory over time with ups and downs and gains and losses. We work from a life course perspective and use growth curve analysis to look at trajectories of change in marital quality over time. Although the tendency is for marital quality to decline over time, some groups begin with much higher levels of marital quality than others. Moreover, a number of life course and contextual factors can accelerate or slow this path of change. Our findings point to the importance of considering the multi-dimensionality of time (e.g., age, marital duration, the passage of years) as well as family transitions (e.g., having children, emptying or refilling the nest) in creating the meanings and experiences of marriage over time. 相似文献

This study investigated the effects of anxiety on nonverbal aspects of speech using data collected in the framework of a large
study of social phobia treatment. The speech of social phobics (N = 71) was recorded during an anxiogenic public speaking task both before and after treatment. The speech samples were analyzed
with respect to various acoustic parameters related to pitch, loudness, voice quality, and temporal aspects of speech. The
samples were further content-masked by low-pass filtering (which obscures the linguistic content of the speech but preserves
nonverbal affective cues) and subjected to listening tests. Results showed that a decrease in experienced state anxiety after
treatment was accompanied by corresponding decreases in (a) several acoustic parameters (i.e., mean and maximum voice pitch,
high-frequency components in the energy spectrum, and proportion of silent pauses), and (b) listeners’ perceived level of
nervousness. Both speakers’ self-ratings of state anxiety and listeners’ ratings of perceived nervousness were further correlated
with similar acoustic parameters. The results complement earlier studies on vocal affect expression which have been conducted
on posed, rather than authentic, emotional speech. 相似文献

Summary This note explores the robustness properties of a general class of ineqyality measures which includes the Bonferroni and the
Gini indexes as special cases and proposes some modifications in order to make them outlier resistant. 相似文献

This paper brings together a range of Australian material concerning family support for the aged. From a review of studies dealing with the family structure of the aged and accounts of inter generational contact and supportive exchanges within families, including migrant families, considerable evidence of family support is found. The implications of the absence of such support are seen from data on the use of services and admissions to institutional care; the preventive effect of marriage and family is apparent, those aged without family being identified as most at risk. Reasons for the commonly held view of family breakdown are then examined and some suggestions for service development outlined. 相似文献

The question of how to measure kurtosis in both symmetric and asymmetric distributions is addressed using the kurtosis diagram of Zenga (2006). Kurtosis is related to inequality at either side of the median, and we establish a hierarchy of kurtosis orderings in which the kurtosis diagram stands at the weakest level. A sufficient condition for constructing kurtosis measures compatible with such ordering is provided. The merits of the proposed approach in both clarifying and formalizing the idea of kurtosis are evaluated and examples are discussed throughout. 相似文献

In this article, we address the problem of mining and analyzing multivariate functional data. That is, data where each observation is a set of possibly correlated functions. Complex data of this kind is more and more common in many research fields, particularly in the biomedical context. In this work, we propose and apply a new concept of depth measure for multivariate functional data. With this new depth measure it is possible to generalize robust statistics, such as the median, to the multivariate functional framework, which in turn allows the application of outlier detection, boxplots construction, and nonparametric tests also in this more general framework. We present an application to Electrocardiographic (ECG) signals. 相似文献
