Children’s Use of a ‘Time Line’ to Indicate When Events Occurred

Children who allege abuse are often asked to provide temporal information such as when the events occurred. Yet, young children often have difficulty recalling temporal information due to their limited knowledge of temporal patterns and linguistic capabilities. As time is an abstract concept (we cannot see it), some investigators have begun to use ‘time-lines’ or pictorial representations of time to aid children. Yet, there is no published research testing whether children are able to use time-lines and whether they can provide adequate temporal information using them. We tested whether children could indicate the time-of-day of events using a pictorial time-line and then compared their responses to their parents’. Seven- to 8-year-olds were most consistent with parental estimates while 4-year-olds were least consistent. Responses from the 5- to 6-year-olds depended on the temporal task. Guessing and using general knowledge to estimate the time-of-day were ruled out, and so children were genuinely drawing on episodic memory when making time-line judgments. Thus, there was a developmental progression in children’s use of physical representations to communicate abstract information. These results are promising for the use of the time-line in forensic settings but much more research is needed.     

A Preliminary Study of the Reliability of Anatomical Facial Landmarks Used in Facial Comparison

Anatomical landmarks are considered the most objective indicators for use in forensic facial comparisons. Therefore, accurately identifying and locating these landmarks is the beginning of reliable facial comparison. This study evaluated the accuracy with which facial landmarks are located and examined their reliability according to type of landmark, head posture, and image quality. Nine operators located a series of landmarks on prepared facial images used to produce comparison images. Then, the average distances between the reciprocal landmarks (ADRL) on the reference and the comparison images were measured as indicators of landmark reliability. We found that a set of landmarks had higher or lower reliability as a function of the head angle and image quality. More reliable landmarks were associated with certain head postures and degrees of image quality. These should be used for facial comparison analysis depending on various head and image conditions.     

An Android Communication App Forensic Taxonomy

Due to the popularity of Android devices and applications (apps), Android forensics is one of the most studied topics within mobile forensics. Communication apps, such as instant messaging and Voice over IP (VoIP), are one popular app category used by mobile device users, including criminals. Therefore, a taxonomy outlining artifacts of forensic interest involving the use of Android communication apps will facilitate the timely collection and analysis of evidentiary materials from such apps. In this paper, 30 popular Android communication apps were examined, where a logical extraction of the Android phone images was collected using XRY, a widely used mobile forensic tool. Various information of forensic interest, such as contact lists and chronology of messages, was recovered. Based on the findings, a two‐dimensional taxonomy of the forensic artifacts of the communication apps is proposed, with the app categories in one dimension and the classes of artifacts in the other dimension. Finally, the artifacts identified in the study of the 30 communication apps are summarized using the taxonomy. It is expected that the proposed taxonomy and the forensic findings in this paper will assist forensic investigations involving Android communication apps.     

Factors that influence engagement in pre-proceedings practice: presenting the roles of professionals working within the family justice system through personal narratives

Public discourse around changes introduced as part of a drive to tackle spending on welfare, reflect a less than tolerant attitude towards welfare generally, but more specifically towards parents who require state involvement to care safely for their children. The introduction of a deadline of 26 weeks for the completion of care proceedings, together with a clear steer to resolve disputes wherever possible prior to making an application to court has introduced further instrumental approaches to working with parents. In this paper we explore practitioner experiences and understandings of working within the new legislative frameworks and consider the dominant cultural narratives they are working within. However, in some cases professionals felt able to challenge the economic narrative of the pre-proceedings protocol, and they experienced the legal and policy changes as an opportunity to engage in a helping alliance with families with the provision of support that otherwise they would not have been able to offer.

Factors influencing help-seeking behavior among battered Korean women in intimate relationships

In total, 123 battered Korean women who used domestic violence agencies were asked where they had turned for assistance in response to intimate partner violence. This study examined the factors related to use of formal and informal resources by these women. Formal resources included police, medical, legal, and shelter; informal were family or neighbors. Findings revealed that (a) the women studied used a variety of resources and that (b) income, violence-related injuries, and partner child abuse were related to whether they contacted police. Injury and partner child abuse were related to contacting a medical doctor/medical facility. Income, relationship status, and partner child abuse were related to approaching family or neighbors. The key finding was that partner child abuse increased the likelihood of battered Korean women seeking help from formal service resources and informal networks. This suggests the need for integrative services that link women's and children's protective services in order to meet the needs of both victims and children.     

Family‐Friendly Human Resource Policy: Is It Still Working in the Public Sector?

The balance between work and family plays a pivotal but evolving role in human resource policy. Ensuring that human resource policy responds to rapidly changing American family demographics, particularly the recent sharp increase in single unmarried Americans, is a major challenge. Compensation policy long has focused on family‐oriented values by promising increased capacity to provide for a family in exchange for higher work performance. Now, employees are voicing concerns about matters such as quality time with family, and, in turn, employers are responding by implementing more benefits to achieve a better work–family balance. Strong counterarguments against human resource goals targeted only at families advocate personal policies that emphasize work–life balance for all employees. How well has personal policy kept pace with the shifting compensation preferences of public employees? Results suggest that implementation policies are keeping pace with employee satisfaction. However, levels of employee satisfaction often differ widely by demographic characteristics.     

Does Family‐Friendly Policy Matter? Testing Its Impact on Turnover and Performance

This study investigates the relative effects of four types of family‐friendly policies—child care subsidies, paid leave for family care, telework, and alternative work schedules—on turnover rates and effectiveness in federal agencies. Contemporary social exchange theory predicts that an agency’s average level of satisfaction with a specific family‐friendly policy is negatively associated with turnover in the agency but positively associated with overall performance. This analysis differs from common expectations. Only child care subsidies show a positive, significant influence on reducing turnover. Child care subsidies and alternative work schedules reflect positive and significant influences on agency effectiveness. Ironically, an agency’s average satisfaction with telework arrangements proves to be a significant but negative effect on performance.

Autosomal short tandem repeat analysis of ancient DNA by coupled use of mini- and conventional STR kits

Abstract: Multiplex autosomal short tandem repeat (STR) genotyping enables researchers to obtain genetic information from ancient human samples. In this study, we tested newly developed AmpF?STR^® MiniFiler? kit for autosomal STR analysis of ancient DNA (aDNA), using human femurs (n = 8) collected from medieval Korean tombs. After extracting aDNA from the bones, autosomal STR analyses were repeated for each sample using the AmpF?STR^® MiniFiler? and Identifiler? kits. Whereas only 21.87% of larger‐sized loci profiles could be obtained with the Identifiler? kit, 75% of the same loci profiles were determined by MiniFiler? kit analysis. This very successful amplification of large‐sized STR markers from highly degraded aDNA suggests that the MiniFiler? kit could be a useful complement to conventional STR kit analysis of ancient samples.
