The contour characteristics of the mucous membrane of the hard palate as dependent on the form of its osseous base]

Analyzes the relief of the hard palate mucosa, depending on the shape of osseous base. Presents data on the prevalence of various morphological shapes of lateral folds in the hard palate mucosa and the levels of their disposition in the ipsiloid, ellipsoid, and parabolic osseous base of the hard palate. Demonstrates the possibility of using the characteristics of the hard palatal mucosa relief as an extra test for personality identification by the oral status.     

Visualization of latent fingerprints using fluorescence lifetime imaging on paper emitting strong fluorescence

Latent fingerprints were successfully visualized using fluorescence lifetime imaging (FLIM) on paper which emits strong fluorescence with a lifetime close to that of fingerprints and thus from which it is difficult for time-resolved spectroscopy to visualize fingerprints. Latent fingerprint samples on paper were excited using a 450 nm or 532 nm nanosecond pulsed-laser, and time-resolved fluorescence images were obtained at a delay time of 6–16 ns in intervals of 1 ns, to the excitation pulse. The excitation beam was expanded using a lens, and the fluorescence from the fingerprints was captured using an intensified CCD camera. Because of the large fluorescence intensity of the background paper of approximately two to four orders of magnitude larger than that of the fingerprint, the fingerprint was not visualized on each fluorescence image by time-resolved spectroscopy. However, the fingerprint was visualized in a FLIM image constructed using a series of the fluorescence images for the case with the fluorescence intensity of the background paper being four orders of magnitude larger than that of the fingerprint. The difference in fluorescence lifetime in the FLIM image of the visualized fingerprint and background paper was in the order of 0.1 ns, which was an order of magnitude smaller than the inherent fluorescence lifetime of a few nanoseconds for the fingerprints and paper. It was demonstrated that, at a background fluorescence intensity with a certain order of magnitude larger than that of fingerprints, FLIM has the potential to visualize latent fingerprints which cannot be visualized by time-resolved spectroscopy.     

Dynamics of Ninhydrin‐Reactive Nitrogen and pH in Gravesoil During the Extended Postmortem Interval

Estimating the postmortem interval of skeletal remains is difficult, as few tools exist to do so. To address this problem, we conducted a field experiment to measure the chemistry of swine (Sus scrofa domesticus Linnaeus) gravesoil after 1 year and 3 years postmortem. Carcasses were placed on the soil surface of a pasture during June in a cold (Dfa) climate. Significant (p < 0.05) increases in ninhydrin‐reactive nitrogen, pH, total nitrogen, and nitrate in gravesoil were detected 1 year postmortem. Significant differences in gravesoil chemistry were not detected 3 years postmortem. These observations coincided with gaps in plant growth 1 year postmortem and the development of lush vegetation 3 years postmortem. We conclude that these phenomena can be used to assist the decision‐making process regarding the allocation of resources during the early stages of a death investigation.     

Anthropological Measurement of the Juvenile Clavicle Using Multi‐Detector Computed Tomography—Affirming Reliability

Currently, there is no standardized protocol for multi‐detector computed tomography (MDCT) measurement of juvenile remains. Using 33 juvenile clavicles, this paper investigates a protocol to allow MDCT measurements, comparable or supplemental with traditional osteometric measurements, to be acquired for application to previously published algorithms. The results illustrate that there is no significant difference between MDCT measurements and those taken by direct osteometric methods. By presenting such a protocol, this paper takes the first steps toward validation of the process of conversion from measurement of dry juvenile bone to MDCT compatibility and allows the forensic world to take a step forward in standardizing the way MDCT is used for forensic practice. This paper assesses the limitations and potential applications of this virtual approach and offers some suggestions for where further work might progress the conversion of these new approaches into legally admissible anthropological techniques of age estimation.     

Development of Latent Fingerprints on Thermal Paper by the Controlled Application of Heat

Apparatus to produce a spatially and temporally uniform heat source is described and this is used to visualize latent fingerprints deposited onto thermal paper by raising the temperature of the paper. Results show an improvement over previous research when fingerprint deposits are aged or the developed fingerprints faint; visualization being enhanced by the use of a blue LED light source of 465 nm peak wavelength. An investigation of the components in fingerprint sweat likely to affect the solubility and hence color change of the dye present in the thermal paper has shown that polar protic solvents able to donate a proton are favored and a polar amino acid found commonly in eccrine fingerprint sweat (lysine) has been shown able to produce the desired color change. Aged fingerprint deposits on thermal paper from a variety of sources up to 4 years old have been visualized with this technique.     

Disqualification of Election Candidates in Nigeria: Some Reflections

Since 1999, when the new democratic governance came into being, there have been three different Electoral Acts in Nigeria. The provisions for disqualification of candidates for election in the 2002 Electoral Act were significantly altered by its 2006 successor. While under the former, the power resided in the Independent Electoral Commission (INEC), the latter completely removed the power from INEC and placed it in the courts. Despite the clear tenor of the new provision, INEC and its sympathizers have continued to hold the view, even in the face of a Supreme Court decision to the contrary, that the 2002 position has not changed. This article sets out to examine this aspect of the electoral process under the 2002 and 2006 Electoral Acts and the cases decided under each, particularly a recent Supreme Court ruling on the matter.     

A Feasibility Pilot Intervention Program to Teach Parenting Skills to Mothers of Poly-Victimized Children

The Parceria (Partnership) Project is a Brazilian intervention program designed for mothers with an intimate partner violence (IPV) history. Its short term goal is to teach parenting skills to abused women, and in the long term, to prevent behavioral problems in their children. The objective of this pilot study was to evaluate the feasibility of the Parceria Project with mothers of children who had experienced multiple forms of maltreatment (poly-victimization), as it was expected that most of the mothers would also have a history of IPV. Seventeen Brazilian mothers took part in this intervention. They completed several types of evaluation. The intervention program using a cognitive-behavioral model took place in each family’s home. All mothers completed the intervention and evaluated the project positively. The study showed that it is feasible to conduct interventions with families who face severe psychosocial risk such as family violence.     

Perceived Parenting Competencies following Childhood Sexual Abuse: A Moderated Mediation Analysis

Childhood sexual abuse (CSA) survivors may face specific challenges in their parental role because of the negative sequelae of their abuse. This study explored factors that might heighten or buffer the risk for problems in parenting for intrafamilial CSA survivors. A community sample of 54 CSA mothers completed questionnaires assessing the severity of their CSA experiences, current depressive symptoms, partner support, and key parenting dimensions. Six moderated mediational models revealed that CSA severity indirectly impacted the survivor’s bond with her child, limit setting ability, communication, and parental involvement through depressive symptoms at high levels of partner support. Partner support was protective against many difficulties in parenting at low levels of depressive symptoms, but did not promote, and at times hindered, effective parenting at high depressive symptoms. This study’s findings highlight the importance of attending to risk and protective factors in understanding parenting among CSA survivors.
