Effect of Temperature on Bone Tissue: Histological Changes

The analysis of burned human remains has been of great interest among forensic anthropologists largely due to the difficulty that their recovery, classification, reconstruction, and identification present. The main purpose of this analysis is to present histological methodology for the interpretation of bones altered by thermal processes. We include analyses of the microscopic changes among bones exposed to different temperatures, with the goal of establishing categories of histological morphology in relation to fire temperature. Samples of bone (ilium) were exposed systematically to controlled temperatures. Analysis of the resulting histological changes has allowed the formation of a clear four‐stage classification of the alterations observed. This classification should prove useful in assessing bone changes in relation to temperature of exposure, particularly in cases where this temperature was previously not known.     

Relationship Between Intimate Partner Violence, Depressive Symptomatology, and Personality Traits

The aim of this study was to examine the relationship between intimate partner violence (IPV) and personality disorder symptoms controlling for depressive state. Victims of IPV (n?=?176) and non-abused women (n?=?193) completed the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), Index of Spouse Abuse (ISA), and Beck Depression Inventory-II (BDI-II). IPV victims scored higher than non-abused women on Intimacy Problems, and scored lower on Rejection traits, after adjustment for depressive symptoms. Severity of the IPV was related to Cognitive Distortion, Suspiciousness, Restricted Expression, and Intimacy Problems, and the length of the IPV was negatively associated with Rejection. The current study suggests only modest differences in personality traits between IPV and non-abused women. The DAPP-BQ traits associated with severity of IPV, in a dose-response manner, would partially reflect the symptoms of complex post-traumatic stress disorder (CPTSD), although this possibility deserves further study.     

The electoral consequences of corruption scandals in Spain

Previous studies of the electoral consequences of corruption in Spanish local elections (Jiménez Revista de Investigaciones Políticas y Sociológicas, 6(2):43–76, 2007; Fernández-Vázquez and Rivero 2011, Consecuencias electorales de la corrupción, 2003–2007. Estudios de Progreso, Fundación Alternativas; Costas et al. European Journal of Political Economy: 28(4):469-484, 2012) have found that voters do not necessarily punish corrupt mayors. As has been pointed out in the comparative literature, the average loss of electoral support by corrupt incumbents is small and does not prevent their reelection most of the times (Jiménez and Caínzos 2006, How far and why do corruption scandals cost votes? In Garrard, J. and Newell, J. (eds.) Scandals in past and contemporary politics. Manchester: Manchester University Press). What remains unsolved, however, is the remarkable variability in this pattern. This article explores some of the micro-level variables that may mediate the effect of corruption scandal on the votes. We focus on three factors: ideological closeness to the incumbent party, political sophistication, and employment status. Our results provide only partial support for our hypotheses, suggesting that the effects of corruption are much more complex than what may seem at first sight.     

Death Due to Decapitation in Two Motorcyclists: A Description of a Unique Case and a Brief Review of the Literature

Deaths due to decapitation, especially related to traffic accidents, are rarely found in forensic practice. The present case involves a man and a woman who died from decapitation due to an unusual mechanism while they were riding on a motorbike down a mountain road. The autopsy, which was completed as a physics study, allowed the accident to be reconstructed as follows: A plastic cable that had detached from a timber‐transporting machine whipped the road and hit the two motorcyclists. The impact resulted in the complete severing of both riders’ heads. Involving different scientists in this accident investigation was crucial to understanding the dynamics of the accident. In fact, in addition to scene inspection and autopsy, a physics study was carried out on the cable and the clamp involved, which led to an explanation for the abrupt movement of the cable and, thus, to a thorough reconstruction of the accident.     

The role of openness in explaining innovation performance in a regional context

We investigate the role of search strategy in shaping firms’ innovation performance. Firms use a wide range of external actors and sources to help them achieve and sustain innovation. In particular, the extension (breadth) and the relevance (depth) of such sources determine firms’ ability to extract and exploit knowledge and new ideas and, thus, to be innovative. Using a sample of firms in a regional context active in R&D, we built separate measures of breadth and depth for local (on a regional scale) and global (outside the regional context) search. This allows us to investigate whether localized or global knowledge spillovers are in place. We find that a wider set of partners increases coordination costs, while greater depth in search strategies contributes to innovation. We find that a more diversified search strategy at the local level (greater breadth of search) results in significant payoffs in terms of innovation, while diversifying the partnership with Italian partners has a smaller, although still positive, effect. In contrast, the benefits of depth of innovation are greatest at the global level. In addition, a broader set of information sources for R&D projects has a significant positive effect on innovation. Finally, firms that resort to R&D subsidies are less innovative.     

Evaluating the Effectiveness of the National Curriculum and Training Institute’s “Cognitive Life Skills” Program among Parolees Supervised by Pennsylvania’s Board of Probation & Parole

Recently, cognitive-behavioral approaches for rehabilitation have shown measured success for reducing recidivism rates among offenders after release from prison. The present analysis utilized data provided by Pennsylvania’s Board of Probation & Parole about offenders who completed the Cognitive Life Skills program developed by the National Curriculum and Training Institute. Propensity scoring techniques were employed to match a group of offenders who completed the program (treatment) with a statistically equivalent group who did not receive it (control). Matching variables included location and year of release, risk level, gender, age, race, offense category, and history of violent offending. General findings from a Cox proportional hazard model revealed gender, age, and criminal history impacted future incidents of recidivism, measured as re-incarceration. More importantly, the hazard model revealed, on average, a 24 % reduction in recidivism among the treatment group offenders and, on average, a 31 % reduction among high risk offenders exclusively. Policy implications will be discussed.     

A Survey of Arts Management Educators' Teaching on Diversity Issues

This study answered two research questions: (1) do arts management educators teach about diversity issues in their courses? If so, how and why? If not, why? (2) Do demographic characteristics impact if an arts management educator teaches about diversity issues in their courses? Most respondents (eighty-six percent) teach about diversity issues in their courses, primarily through discussion (ninety-one percent), and most (ninety-nine percent) believe arts management students should receive education on diversity issues in the arts. This study is significant because no known inquiry into the teaching practices of arts management educators relative to diversity issues in the arts previously existed.     

Biological variability of the minutiae in the fingerprints of a sample of the Spanish population

The minutiae, a term coined by Galton to refer to the small peculiarities present along the length of every isolated ridge, or characteristic points, a term used primarily by the Spanish Police Scientists, have an inter- and intrapopulation variability which has not been extensively studied. However, these peculiarities constitute the bases for the fingerprint identification of individuals in the field of criminology. Using the adhesive paper and graphite method, the fingerprints of 200 students, 100 males and 100 females, with ages ranging between 20 and 35, have been taken at the University of Alcala (Madrid). From this sample, the distal phalanx of the index finger of the right hand has been studied. The total count of the minutiae, as well as that of each different type, was made of the entire print area, and inside and outside of a circle with a radius of 18 ridges. The highest frequencies were of ridge endings, followed by bifurcations and convergences, all others appearing with frequencies of lower than 5%. The distribution of the minutiae was not homogeneous for the area of the fingerprint (inside and outside the circle). In the study of minutiae statistically significant differences were found between the sexes, and between the different types of general pattern (arches, loops, and whorls).     

Fast LC-MS/MS method for the determination of amphetamine, methamphetamine, MDA, MDMA, MDEA, MBDB and PMA in urine

A fast method was designed for the simultaneous determination of amphetamine (A), methamphetamine (MA), PMA, MDA, MDMA, MDEA and MBDB in urine. The drugs were analysed by LC (ESI)-MS/MS, after a simple liquid-liquid extraction in the presence of the deuterated analogues. Reverse phase separation on an Atlantis dC18 Intelligent Speed column was achieved in less than 4 min under gradient conditions, and the total run time was 8 min. The method was fully validated, including linearity (1-1000 ng/mL for A, MDMA, MDEA and MBDB; 2-1000 ng/mL for MDA and PMA; 1-200 ng/mL for MA; r2>0.99 for all compounds), recovery (>80%), within-day and between-day precision and accuracy (CV and MRE<12.7% for intermediate level and ULOQ, and <17.2% for LLOQ), limit of detection (0.2 ng/mL for MDMA, MDEA and MBDB; 0.5 ng/mL for A, MA and PMA; 1 ng/mL for MDA) and quantitation (1 ng/mL for A, MA, MDMA, MDEA and MBDB; 2 ng/mL for MDA and PMA) and relative ion intensities. No matrix effect was observed. The procedure proved to be sensitive, specific and rapid, and was applied to real forensic cases.     

Allele frequencies of 15 autosomal STR loci in the Iraq population with comparisons to other populations from the middle-eastern region

Allele frequencies for the 15 autosomal STR loci included in the AmpFlSTR((R)) IdentifilerTM PCR Amplification Kit panel from Applied Biosystems (D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, TH01, TPOX, CSF1PO, D19S433, D2S1338, D16S539) and several statistical parameters were estimated from a sample of 103 unrelated individuals, mostly Shia and Sunni Arabs, living in most of central and southern Iraq provinces. We compared the allele frequency spectrum detected in the Iraqi population to allele frequencies from 11 other data sets from published studies of individuals from Turkey, Iraqi-Kurdistan, Saudi Arabia, Arab Emarates, Oman, Iran, Syria, and Jordan. Significant global differences in allele frequencies were detected in 9 of the 11 comparisons following sequential Bonferroni corrections. Comparisons with the two independent panels from Saudi Arabia were not significant after applying Bonferroni corrections, however, low P-values (P<0.05) associated with these two contrasts nonetheless suggested that at least slight genetic differences between populations may exist.
