Public Perceptions Of Female Offenders And Their Treatment Needs
There has been an abundance of research examining public perceptions toward various areas of the criminal justice system. Much of this research has focused on measuring public support toward punishment and rehabilitation for offenders within prison. However, less is known with regards to public attitudes toward female offenders. The current study examined public perceptions toward rehabilitation among offenders in general, and female offenders in particular, the risk factors that contribute to female offenders committing crimes, and toward various issues that are common among female offenders and their subsequent treatment needs. Two hundred and fifty participants were recruited through Amazon Mechanical Turk where respondents responded to four questionnaires that measured their perceptions toward offender rehabilitation, female offender risk factors, female offender characteristics, and female offender treatment. The results of this study concluded that the public is supportive of rehabilitation among offenders. In addition, the public requires more education regarding the risk factors that contribute to female offenders committing crimes, specifically in the areas of family and marital problems, emotional and personal issues, and substance use and abuse. However, results of this study indicated that the public is knowledgable on the issues that are common among female offenders and are supportive of rehabilitation among this offender population. The policy implications of these findings are discussed, limitations are addressed, and directions for future research are considered
Le rôle de la résonance magnétique nucléaire dans le diagnostic et la localisation du cancer rectal
Département de radiologie et d'imagerie, Université d'État de médecine et de pharmacie “Nicolae Testemitanu”
Chisinau, République de Moldavie,
The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Introduction: Le cancer rectal, bien qu'il partage de nombreuses caractéristiques du carcinome colorectal, a quelques aspects individuels.
Ceux-ci sont principalement liés à sa position anatomique, ce qui a des implications dans l'imagerie préopératoire et l'évaluation de la
technique chirurgicale. Bien que la tomodensitométrie (TDM) puisse faire le diagnostic, la résonance magnétique nucléaire (RMN) est
devenue le point d'arrêt préopératoire. L'étude visait à évaluer la contribution de la résonance magnétique nucléaire (RMN) dans la détection
du cancer rectal par localisation, propagation locorégionale et diagnostic différentiel avec le cancer sigmoïde et anal.
Matériel et méthodes: Un groupe de 24 patients, ayant un cancer colorectal suspecté, a été examiné par RMN du petit bassin entre août
2014 et décembre 2017.
Résultats: Suite à l'étude, les 24 patients atteints d'un cancer colorectal présumé ont été diagnostiqués avec un cancer rectal de localisation
variée. Parmi ceux-ci: cancer rectal supérieur – 6 patients (25%); cancer rectal moyen – 3 patients (12,5%); cancer rectal inférieur – 8 patients
(33,3%); mixtes – 7 patients (29,2%), dont: supérieur et moyen – 2 patients (8,3%), moyen et inférieur – 5 patients (20,9%).
Conclusions: L'incidence élevée des cas de cancer rectal supérieur (CRS) et inférieur (CRI), par rapport au cancer rectal moyen, nécessite un
diagnostic différentiel rigoureux entre le CRS et le cancer sigmoïde et CRI et le cancer anal, la RMN du petit bassin est la méthode d'imagerie
de choix, en raison de l'excellent contraste des tissus mous et l'absence de rayonnement ionisant
pH-sensitivity of YFP provides an intracellular indicator of programmed cell death.
BACKGROUND: Programmed cell death (PCD) is an essential process for the life cycle of all multicellular organisms. In higher plants however, relatively little is known about the cascade of genes and signalling molecules responsible for the initiation and execution of PCD. To aid with the discovery and analysis of plant PCD regulators, we have designed a novel cell death assay based on low cytosolic pH as a marker of PCD. RESULTS: The acidification that occurs in the cytosol during plant PCD was monitored by way of the extinction of YFP fluorescence at low pH. This fluorescence was recovered experimentally when bringing the intracellular pH back to 7, demonstrating that there was no protein degradation of YFP. Because it uses YFP, the assay is none-destructive, does not interfere with the PCD process and allows time-lapse studies to be carried out. In addition, changes of sub-cellular localisation can be visualised during PCD using the protein of interest fused to RFP. Coupled to a transient expression system, this pH-based assay can be used to functionally analyse genes involved in PCD, using point mutations or co-expressing PCD regulators. Transfecting mBAX and AtBI-1in onion epidermal cells showed that the pH shift is downstream of PCD suppression by AtBI-1. In addition, this method can be used to score PCD in tissues of stably transformed transgenic lines. As proof of principle, we show the example of YFP extinction during xylogenesis in Arabidopsis. This demonstrates that the assay is applicable to PCD studies in a variety of tissues. CONCLUSIONS: The observation that YFP fluorescence is lost during the plant PCD process provides a new tool to study the genetic regulation and cell biology of the process. In addition, plant cell biologists should make a note of this effect of PCD on YFP fluorescence to avoid misinterpretation of their data and to select a pH insensitive reporter if appropriate. This method represents an efficient and streamlined tool expected to bring insights on the process leading to the pH shift occurring during PCD
European motor insurance demand: a spatial approach of its effects and key determinants
The expansion of the European Union has intensified road traffic
from, at least, two perspectives: it increased free mobility of people
and goods, along with structural funds available for infrastructure
improvement. Consequently, connections between regions/countries
have improved, and a spatial diffusion effect is seen in the car
transportation behaviour. We study the effect of Human
Development Index (HDI) along with other important socio-economic,
demographic and institutional factors on the motor insurance
market in 31 European countries. Simultaneously, we evaluate if the
crucial spatial diffusion effect is present on the European motor
insurance market. Findings reveal that HDI, urbanization and car fleet
positively impact the motor insurance market, while unemployment
and population density exhibit an opposite effect. Overall, results are
robust to a set of additional control factors, but sensitive relative to
institutional factors and emerging and former communist countries
group. Estimations confirm the assumption of spatial diffusion, while
the assessment of the direct and indirect effects shows that most of
the factors internally impact the dependent variable, and an international
effect is at work for the HDI. Our findings may enhance the
understanding of the European motor insurance market and provide
some valuable insights from a policy perspectiv
Experimental and theoretical study of light scattering by individual mature red blood cells by use of scanning flow cytometry and discrete dipole approximation
Elastic light scattering by mature red blood cells (RBCs) was theoretically
and experimentally analyzed with the discrete dipole approximation (DDA) and
the scanning flow cytometry (SFC), respectively. SFC permits measurement of
angular dependence of light-scattering intensity (indicatrix) of single
particles. A mature RBC is modeled as a biconcave disk in DDA simulations of
light scattering. We have studied the effect of RBC orientation related to the
direction of the incident light upon the indicatrix. Numerical calculations of
indicatrices for several aspect ratios and volumes of RBC have been carried
out. Comparison of the simulated indicatrices and indicatrices measured by SFC
showed good agreement, validating the biconcave disk model for a mature RBC. We
simulated the light-scattering output signals from the SFC with the DDA for
RBCs modeled as a disk-sphere and as an oblate spheroid. The biconcave disk,
the disk-sphere, and the oblate spheroid models have been compared for two
orientations, i.e. face-on and rim-on incidence. Only the oblate spheroid model
for rim-on incidence gives results similar to the rigorous biconcave disk
model.Comment: 13 pages, 9 figure
