Ancestry and BMI Influences on Facial Soft Tissue Depths for A Cohort of Chinese and Caucasoid Women in Dunedin,New Zealand

This study measured and assessed facial soft tissue depths (FSTDs) in adult female Chinese and New Zealand (NZ) Europeans (Caucasoids). Ultrasound was used to obtain depths at nine landmarks on 108 healthy subjects (51 Chinese, 57 NZ European), erect positioned, of same age group (18–29 years). Height and weight were also recorded. Statistical analysis focused on comparison of tissue depth between the two ancestry groups and the influence of Body Mass Index (BMI) (kg/m²). Results showed mean depth differences at Supra M2 and Infra M2 landmarks significantly greater for Chinese than Caucasoid women for all three BMI Classes (BMI <20, 20 ≤ BMI < 25, 25 ≤ BMI < 30), even BMI <20. For both groups BMI positively correlated with FSTD values at all landmarks except Labrale superius. This study enabled ancestry and BMI influence on FSTDs to be observed and compared for two distinct groups. Results add to knowledge about facial tissue depth variation.     

Position Effect on Facial Soft Tissue Depths: A Sonographic Investigation

The head is positioned erect for an approximation; yet most facial soft tissue depths (FSTD) used are measured from supine subjects. Depth difference might be significant, but there is a paucity of data to verify. This study compared erect and supine values for 17 landmarks from 30 healthy New Zealand (European population affinity) women (18–30 or 40–55 years) in erect then supine positions. Height, weight, and sonographic FSTD data, totaling 1020 measurements, were obtained. Three midline and seven averaged bilateral values were compared using ANOVA, p values, and Pearson's correlations. Correlative strength of age and body mass index, BMI (kg/m²), was determined by values. Results showed averaged erect and supine differences were significant for four of ten FSTDs. Between individuals, difference was various and not unidirectional. In conclusion, depth differences were observed but not all significant or unidirectional, BMI significantly influenced nine FSTD values, but age group did not.     

Physical and mechanical degradation of shirting fabrics in burial conditions

The current focal areas within forensic textile science are fibre identification and assessment of the method of damage to fabrics. This paper investigates fabric degradation within clandestine burials. The fabrics considered in this paper, unlike previous archaeological studies, are a modern polyester-cotton blend (65%/35%) and a 100% cotton fabric both of which are commonly used for men's shirting fabrics in the UK. Three laundering conditions were investigated (i) not-laundered, (ii) laundered 6 times, and (iii) laundered 60 times; this represented varying conditions of fabric upon clothing deposition. The two burial conditions; sand and clay, were selected as extremes of soil type. The deposition times (15 and 30 days) were based on a study of clandestine burials in UK crimes. There were clear differences in how polyester-cotton and cotton stained within the two different soil conditions, polyester-cotton becoming extensively stained after a 30-day deposition in sand. The tear force required to tear the fabric after deposition, suggested that polyester/cotton fabrics were consistently weaker after burial, regardless of soil type and deposition period. There was also significant damage caused to not-laundered cotton fabrics after a 30-day deposition in clay. This work indicates that common apparel fabrics can degrade in relatively short times when buried.     

The Limits of Mobilization: Turnout Evidence from State House Primaries

Many analysts have lamented the decline of political mobilization efforts. They suggest that the cause of worsening voter turnout may be traceable to the failure of political candidates and political parties to target and activate nonvoters. This research explores the effects of face-to-face mobilization efforts in a sample of September 5, 2000, Florida state house primary races. Controlling for their voting history, the face-to-face mobilization effort did increase turnout by about 8% among those contacted. However, the effects were weakest among those who voted least regularly. The results suggest that implementing more face-to-face mobilization efforts would increase turnout—mostly by encouraging occasional voters to go to the polls. However, those same mobilization efforts would not substantially affect the turnout of chronic nonvoters.

“What's Newt Doing in People Magazine?” The Changing Effect of National Prominence in Congressional Elections

It is conventional wisdom in politics to believe that press coverage is beneficial. However, forms of press coverage are not created equal. Specifically, we argue that national media prominence is not inherently beneficial and can be detrimental to members of Congress. Using a measure of national prominence based on the number of national television appearances of House incumbents, this study finds national prominence was generally not a significant positive factor in incumbent popularity from 1982 to 1988. Moreover, after the anti-Washington, anti-incumbent mood burgeoned in the interim, national prominence became an important factor for incumbents, such that those who were more prominent in the elections of 1990–1996 were penalized.     

Tearing of knicker fabrics

In Dunedin (South Island, New Zealand), a sexual assault is reported to police approximately once every two to three weeks, with some reports fictitious. Identifying a fictitious claim is difficult, and damage to apparel, especially knickers, may be the only form of evidence. In this paper, the tear behaviour of three knit fabrics, typical of those used to manufacture knickers is reported: the effect of laundering prior to tearing was considered. Tearing behaviour was determined using an Instron universal testing machine (Model 4464) operating in tensile mode to eliminate variability which is inevitable with human participants. Cotton and cotton-rich fabrics were more difficult to tear than modal-rich fabrics: the addition of elastane increased the time for the tear initiation as elastane fibres allowed the fabric to extend more before breaking. Specimens behaved differently depending on which direction they were torn (course-direction specimens down the length of the specimen, wale-direction specimens 50% down the length, 50% across the specimen). Laundered fabrics required less force to tear than new fabrics, therefore, when examining torn apparel, the fibre content and age of the garment need to be considered. Torn fibre ends appeared similar to those damaged by other means (e.g. knife, screwdriver) and no features visible under FESEM could be attributed solely to tearing damage in the fabrics studied.
