This study aimed to establish preliminary estimates and related risk factors for elder abuse among Hong Kong Chinese families. A total of 276 elder Chinese participated in the study, among which 27.5% reported having experienced at least one abusive behavior committed against them by their caregivers during the surveyed year. The most common form of abuse was verbal abuse (26.8%), whereas physical abuse (2.5%) and violation of personal rights (5.1%) were relatively less common. There was no gender difference in the prevalence of elder abuse. Overall and verbal abuse were best predicted by participants' poor visual and memory abilities, dependence on the caregivers, and caregivers' nondependence on them. Physical abuse was best predicted by caregivers' nondependence on the participants as well as participants' dependence on the caregivers. Participants' age was the only significant predictor for violation of personal rights. Results, limitations, and implications of the study were also discussed.  相似文献

Biological fluid identification is an important facet of evidence examination in forensic laboratories worldwide. While identifying bodily fluids may provide insight into which downstream DNA methods to employ, these screening techniques consume a vital portion of the available evidence, are usually qualitative, and rely on visual interpretation. In contrast, qPCR yields information regarding the amount and proportion of amplifiable genetic material. In this study, dilution series of either semen or male saliva were prepared in either buffer or female blood. The samples were subjected to both lateral flow immunochromatographic test strips and qPCR analysis. Analytical figures of merit—including sensitivity, minimum distinguishable signal (MDS) and limit of detection (LOD)—were calculated and compared between methods. By applying the theory of the propagation of random errors, LODs were determined to be 0.05 μL of saliva for the RSID? Saliva cards, 0.03 μL of saliva for Quantifiler® Duo, and 0.001 μL of semen for Quantifiler® Duo. In conclusion, quantitative PCR was deemed a viable and effective screening method for subsequent DNA profiling due to its stability in different matrices, sensitivity, and low limits of detection.  相似文献

Estimating age at death is one of the most important aspects of creating a biological profile. Most adult age estimation methods were developed on North American skeletal collections from the early to mid‐20th century, and their applicability to modern populations has been questioned. In 2010, Hartnett used a modern skeletal collection from the Maricopia County Forensic Science Centre to revise the Suchey‐Brooks pubic symphysis method and the ??can et al. fourth rib methods. The current study tests Hartnett's revised methods as well as the original Suchey‐Brooks and ??can et al. methods on a modern sample from the William Bass Skeletal Collection (N = 313, mean age = 58.5, range 19–92). Results show that the Suchey‐Brooks and ??can et al. methods assign individuals to the correct phase 70.8% and 57.5% of the time compared with Hartnett's revised methods at 58.1% and 29.7%, respectively, with correctness scores based on one standard deviation of the mean rather than the entire age range. Accuracy and bias scores are significantly improved for Hartnett's revised pubic symphysis method and marginally better for Hartnett's revised fourth rib method, suggesting that the revised mean ages at death of Hartnett's phases better reflect this modern population. Overall, both Hartnett's revised methods are reliable age estimation methods. For the pubic symphysis, there are significant improvements in accuracy and bias scores, especially for older individuals; however, for the fourth rib, the results are comparable to the original ??can et al. methods, with some improvement for older individuals.  相似文献

Objectives

Explore Bayesian spatio-temporal methods to analyse local patterns of crime change over time at the small-area level through an application to property crime data in the Regional Municipality of York, Ontario, Canada.

Methods

This research represents the first application of Bayesian spatio-temporal modeling to crime trend analysis at a large map scale. The Bayesian model, fitted by Markov chain Monte Carlo simulation using WinBUGS, stabilized risk estimates in small (census dissemination) areas and controlled for spatial autocorrelation (through spatial random effects modeling), deprivation, and scarce data. It estimated (1) (linear) mean trend; (2) area-specific differential trends; and (3) (posterior) probabilities of area-specific differential trends differing from zero (i.e. away from the mean trend) for revealing locations of hot and cold spots.

Results

Property crime exhibited a declining mean trend across the study region from 2006 to 2007. Variation of area-specific trends was statistically significant, which was apparent from the map of (95 % credible interval) differential trends. Hot spots in the north and south west, and cold spots in the middle and east of the region were identified.

Conclusions

Bayesian spatio-temporal analysis contributes to a detailed understanding of small-area crime trends and risks. It estimates crime trend for each area as well as an overall mean trend. The new approach of identifying hot/cold spots through analysing and mapping probabilities of area-specific crime trends differing from the mean trend highlights specific locations where crime situation is deteriorating or improving over time. Future research should analyse trends over three or more periods (allowing for non-linear time trends) and associated (changing) local risk factors.  相似文献

Using lifetime data from two waves of the National Epidemiologic Surveys on Alcohol and Related Conditions, this study sought to examine sex- and race-specific risks in the temporal relationship between adult onset severe physical intimate partner violence (IPV) victimization and alcohol misuse (binge drinking) and alcohol use disorders (abuse and dependence) and whether or not childhood trauma moderated these relationships among U.S. non-Hispanic White and Black women and men. IPV predicted most alcohol outcomes among White and Black women and White men. Conversely, binge drinking among White and Black women and alcohol abuse among Black women and men predicted IPV. Childhood trauma moderated the relationship between IPV and alcohol misuse mainly among Black respondents, with an increased risk of either outcome among those without childhood trauma. These findings suggest a reciprocal relationship between IPV victimization and alcohol misuse, with implications for sex- and race-specific prevention and intervention efforts.  相似文献

On November 24, 2013, Egypt's signed into law - the Public Protest interim President Adly Mansour Law after it was proposed by the interim government, and soon it became the main concern in Egypt due to claim that after the ousting of President Mohamed Morsi and of the Muslim Brotherhood, the country is currently ruled by a military-backed government that seeks to restrict freedom and rights in order to introduce a new authoritarian-military rule. The government promoted the law by arguing that it aims to maintain stability and security in Egypt's streets and that it only targets factional protest movements and saboteurs. Nevertheless, the law has been widely criticized by human rights groups as well as rights and political activists who say it restricts freedom of speech and that it is an attempt to completely ban the right to protest, not to regulate it as the government claims.  相似文献

Indonesia had been colonized by Dutch Government for more than 300 years. Posterior to Indonesia independent proclamation on August 17, 1945 there was a number of State's legal problems found and one of them is the control and tenure arrangement of private property that left by Dutch citizens in the country of Indonesia. Specific purpose of the paper is to criticize the existence of Act Number 3 PRP Year 1960 regarding the Tenure Arrangements Fixed Objects Dutch Citizens Private Property that has reflected a sense of unjust, uncertainty and inexpedience for the greatest number of Indonesian people. It is because the Act of 1960 defines inconsistency between Article 4, paragraph (2) with general explanations Article 1 Government Regulation of the Republic of Indonesia Number 223 of 1961. It also set the terms of priorities to obtain fixed objects belonging to individual citizens Dutch not in accordance with the principle of equality before the law. Legal implications arising from control and tenure arrangements of objects and equipment owned by a Dutch individual are a problem that occurs in the received ground objects P3MB. To implement the control arrangements of objects and equipment owned by a Dutch individual that reflects a sense of fairness, certainty and benefit to society by applying the concept of 3 in 1 in the Land Acquisition: Acquisition of land objects P3MB for laws subject.  相似文献
