Correctional Institution Response to Deviant Behavior: An Evaluation of Correctional Institution Rehabilitation Treatment Programs

There have been countless studies on criminals, treatment and recidivism, however, there is still no simple solution. The treatment programs at Dillwyn Correctional Center were design and taught by the Correctional Institution Rehabilitation Counselors. These treatment programs were enacted in hopes of aiding the offender in leading a crime free life in the future. Theorist Sutherland and Gillin both submit that it is possible for a convict to be reformed through a process of interaction with the do-gooders of society and a regime of work and education to be reborn as a lawful individual. Therefore, the treatment programs enacted at Dillwyn Correctional Center are deemed as unsuccessful

Communicating complex ecological models to non-scientist end users

Complex computer models are used to predict how ecological systems respond to changing environ- mental conditions or management actions. Communicating these complex models to non-scientists is challenging, but necessary, because decision-makers and other end users need to understand, accept, and use the models and their predictions. Despite the importance of communicating effectively with end users, there is little guidance available as to how this may be achieved. Here, we review the challenges typically encountered by modellers attempting to communicate complex models and their outputs to managers and other non-scientist end users. We discuss the implications of failing to communicate effec- tively in each case. We then suggest a general approach for communicating with non-scientist end users. We detail the specific elements to be communicated using the example of individual-based models, which are widely used in ecology. We demonstrate that despite their complexity, individual-based models have characteristics that can facilitate communication with non-scientists. The approach we propose is based on our experiences and methods used in other fields, but which until now have not been synthesised or made broadly available to ecologists. Our aim is to facilitate the process of communicating with end users of complex models and encourage more modellers to engage in it by providing a structured approach to the communication process. We argue that developing measures of the effectiveness of communication with end users will help increase the impact of complex models in ecology

Facing Aggression: Cues Differ for Female versus Male Faces

The facial width-to-height ratio (face ratio), is a sexually dimorphic metric associated with actual aggression in men and with observers' judgements of aggression in male faces. Here, we sought to determine if observers' judgements of aggression were associated with the face ratio in female faces. In three studies, participants rated photographs of female and male faces on aggression, femininity, masculinity, attractiveness, and nurturing. In Studies 1 and 2, for female and male faces, judgements of aggression were associated with the face ratio even when other cues in the face related to masculinity were controlled statistically. Nevertheless, correlations between the face ratio and judgements of aggression were smaller for female than for male faces (F1,36 = 7.43, p = 0.01). In Study 1, there was no significant relationship between judgements of femininity and of aggression in female faces. In Study 2, the association between judgements of masculinity and aggression was weaker in female faces than for male faces in Study 1. The weaker association in female faces may be because aggression and masculinity are stereotypically male traits. Thus, in Study 3, observers rated faces on nurturing (a stereotypically female trait) and on femininity. Judgements of nurturing were associated with femininity (positively) and masculinity (negatively) ratings in both female and male faces. In summary, the perception of aggression differs in female versus male faces. The sex difference was not simply because aggression is a gendered construct; the relationships between masculinity/femininity and nurturing were similar for male and female faces even though nurturing is also a gendered construct. Masculinity and femininity ratings are not associated with aggression ratings nor with the face ratio for female faces. In contrast, all four variables are highly inter-correlated in male faces, likely because these cues in male faces serve as “honest signals”

Check the gap: Facemask performance and exhaled aerosol distributions around the wearer.

Current facemask research focuses on material characterization and efficiency; however, facemasks are often not tested such that aerosol distributions are evaluated from the gaps in the sides, bottom, and nose areas. Poor evaluation methods could lead to misinformation on optimal facemasks use; a high-throughput, reproducible method which illuminates the issue of fit influencing aerosol transmission is needed. To this end, we have created an in vitro model to quantify particle transmission by mimicking exhalation aerosols in a 3D printed face-nose-mouth replica via a nebulizer and quantifying particle counts using a hand-held particle counter. A sewn, sewn with pipe cleaner nose piece, and sewn with a coffee filter facemask were used to evaluate current common homemade sewn facemask designs, benchmarked against industry standard surgical, N95 respirator tightly fit, and N95 respirator loosely fit facemasks. All facemasks have significantly reduced particle counts in front of the facemask, but the side and top of the facemask showed increases in particle counts over the no facemask condition at that same position, suggesting that some proportion of aerosols are being redirected to these gaps. An altered size distribution of aerosols that escape at the vulnerable positions was observed; escaped particles have larger count median diameters, with a decreased ratio of smaller to larger particles, possibly due to hygroscopic growth or aggregation. Of the homemade sewn facemasks, the facemask with a coffee filter insert performed the best at reducing escaped aerosols, with increased efficiency also observed for sewn masks with a pipe cleaner nose piece. Importantly, there were minimal differences between facemasks at increasing distances, which supports that social distance is a critical element in reducing aerosol transmission. This work brings to light the importance of quantifying particle count in positions other than directly in front of the facemask and identifies areas of research to be explored

Low heat shock thresholds in wild Antarctic intertidal limpets (Nacella concinna).

Heat shock proteins (HSPs) are a family of genes classically used to measure levels of organism stress. We have previously identified two HSP70 genes (HSP70A and HSP70B) in sub-tidal populations of the Antarctic limpet (Nacella concinna). These genes are up-regulated in response to increased seawater temperatures of 15°C or more during acute heat shock experiments, temperatures that have very little basis when considering the current Antarctic ecology of these animals. Therefore, the question was posed as to whether these animals could express HSP70 genes when subjected to more complex environmental conditions, such as those that occur in the inter-tidal. Inter-tidal limpets were collected on three occasions in different weather conditions at South Cove, Rothera Point, over a complete tidal cycle, and the expression levels of the HSP70 genes were measured. Both genes showed relative up-regulation of gene expression over the period of the tidal cycle. The average foot temperature of these animals was 3.3°C, far below that of the acute heat shock experiments. These experiments demonstrate that the temperature and expression levels of HSP production in wild animals cannot be accurately extrapolated from experimentally induced treatments, especially when considering the complexity of stressors in the natural environment. However, experimental manipulation can provide molecular markers for identifying stress in Antarctic molluscs, provided it is accompanied by environmental validation, as demonstrated here

Increased Bone Volume and Correction of HYP Mouse Hypophosphatemia in the Klotho/HYP Mouse

Inactivating mutations of PHEX cause X-linked hypophosphatemia and result in increased circulating fibroblast growth factor 23 (FGF23). FGF23 action is dependent upon Klotho, which converts FGF receptor 1 into an FGF23-specific receptor. Disruption of Klotho results in a complex bone phenotype and hyperphosphatemia, the converse phenotype of X-linked hypophosphatemia. We examined effects of disrupting both Klotho and PHEX by creating a double-knockout (Klotho/HYP) mouse. The combined disruption corrected the hypophosphatemia in HYP mice, indicating that Klotho is epistatic to PHEX. FGF23 levels remained elevated in all groups except wild-type, indicating that Klotho is necessary for FGF23-dependent phosphaturic activity. 1,25-Dihydroxyvitamin D levels, reduced in HYP mice, were comparably elevated in Klotho and Klotho/HYP mice, demonstrating that Klotho is necessary for FGF23’s effect on vitamin D metabolism. Serum PTH levels were reduced in both Klotho and Klotho/HYP mice. Moreover, the Klotho null phenotype persisted in Klotho/HYP, maintaining the runty phenotype and decreased life span of Klotho null mice. Notably, microcomputed tomography analysis demonstrated greater trabecular bone volume fraction in Klotho/HYP mice than that in all other groups (Klotho/HYP, 56.2 ± 6.3%; Klotho, 32.5 ± 10.3%; HYP, 8.6 ± 7.7%; and wild type, 21.4 ± 3.4%; P < 0.004). Histomorphometric analysis confirmed the markedly increased trabecular bone density in Klotho/HYP mice and the well-established increase in osteoid volume in HYP mice. These observations suggest that with addition of Klotho loss of function, the overabundant osteoid typically produced in HYP mice (but fails to mineralize) is produced and mineralized in the double knockout, resulting in markedly enhanced trabecular bone density

Culturally sustaining pedagogy within monolingual language policy: variability in instruction

This 5-month ethnographic comparative case study of two culturally and linguistically diverse U.S. elementary classrooms juxtaposes restrictive educational language policies with the theoretical principles of culturally sustaining pedagogy to explore a gap in our understanding of how teachers reflect educational language policies in the range of pedagogical approaches they take. Triangulating data sources from state and local policy documents, classroom observations, and teacher interviews, we identify three salient dimensions of state and local policies that manifested in these two upper-elementary classrooms: teachers' curricular and pedagogical choices; student-teacher participation structures; and teachers' views on language. Similarities and differences between the two classrooms highlight how policy exerts influence on these dimensions while also affording degrees of instructional freedom that varied by teacher, with implications for the learning opportunities for culturally and linguistically diverse students. Overall, however, a limited range of culturally sustaining practices was observed, highlighting the need to understand the spaces in language policy where teachers can mitigate some of the effects of restrictive regulatory approaches to learning. © 2013 Springer Science+Business Media Dordrecht
