Specter of Reform: Understanding the Violent Crime Control and Law Enforcement Act of 1994 and its Role in Expanding the Modern Prison Industrial Complex

The United States incarcerates more of its citizens than any other nation in recorded history, and currently houses roughly 25% of the world’s prison population. Though the US prison population dipped in 2016 to its lowest rate since 1993, the sheer number of people under the supervision of the criminal justice system within the country is staggering. As of 2012, one in one hundred adults in the US are in jail or prison, which makes the US the nation with the world’s largest prison population. The US also leads the world in rate of incarceration. Thus, the nation’s prisons teem with bodies at the federal and state level. Whether one refers to this phenomenon as the carceral state, mass incarceration, or the prison industrial complex, the use of such terms endeavor to codify the notion America incarcerates too many people. The federalization of criminal law, culminating in the Violent Crime Control and Law Enforcement Act of 1994, which led to explosive federalization of the criminal code and laid the infrastructure for the mechanism for incarcerating people at explosive rates. This critical essay will interrogate the dynamics of the infamous Violent Crime Control and Law Enforcement Act of 1994 and its role in expanding the modern prison Industrial Complex, and will center the specific contributions of the late Senator Arlen Specter to interrogate his efforts to achieve more equitable criminal justice advocacy. A principal objective of Specter of Reform is to maneuver beyond intense racially-charged rhetorical debates of the modern prison industrial complex and to examine how various efforts aimed at reducing violent crime exacerbated the disproportionate rate of Black male incarceration

HostelDesk: Multimedia incident reporting application

Applied project submitted to the Department of Computer Science and Information Systems, Ashesi University, in partial fulfillment of Bachelor of Science degree in Computer Science, May 2021University hostels owned by individuals cannot afford to hire multiple personnel to manage the hostels’ operations, from booking students to maintaining facilities. Instead, they employ individual persons to handle the day-to-day activities in the hostel since these owners cannot be available all the time. Due to the manager’s many responsibilities, they often focus on general problems and neglect issues reported by students creating frustration and dissatisfaction. With the many issues occurring around the hostel, these managers often either find it challenging to keep track of these problems and/or forget these problems unless reminded by students. The project seeks to design a hostel front desk incident reporting application based on data obtained from a survey questionnaire administered to students and managers of hostels. The HostelDesk, an incident reporting application, should assist managers receive reports from students and attend to multiple issues promptly. Again, it can help students report their issues promptly without waiting for personnel. This paper seeks to improve the communication gap between students and managers in solving problems in hostels.Ashesi Universit

Relative performance of indoor vector control interventions in the Ifakara and the West African experimental huts.

BACKGROUND: West African and Ifakara experimental huts are used to evaluate indoor mosquito control interventions, including spatial repellents and insecticides. The two hut types differ in size and design, so a side-by-side comparison was performed to investigate the performance of indoor interventions in the two hut designs using standard entomological outcomes: relative indoor mosquito density (deterrence), exophily (induced exit), blood-feeding and mortality of mosquitoes. METHODS: Metofluthrin mosquito coils (0.00625% and 0.0097%) and Olyset® Net vs control nets (untreated, deliberately holed net) were evaluated against pyrethroid-resistant Culex quinquefasciatus in Benin. Four experimental huts were used: two West African hut designs and two Ifakara hut designs. Treatments were rotated among the huts every four nights until each treatment was tested in each hut 52 times. Volunteers rotated between huts nightly. RESULTS: The Ifakara huts caught a median of 37 Culex quinquefasciatus/ night, while the West African huts captured a median of 8/ night (rate ratio 3.37, 95% CI: 2.30-4.94, P  4-fold higher mosquito exit relative to the West African huts (odds ratio 4.18, 95% CI: 3.18-5.51, P < 0.0001), regardless of treatment. While blood-feeding rates were significantly higher in the West African huts, mortality appeared significantly lower for all treatments. CONCLUSIONS: The Ifakara hut captured more Cx. quinquefasciatus that could more easily exit into windows and eave traps after failing to blood-feed, compared to the West African hut. The higher mortality rates recorded in the Ifakara huts could be attributable to the greater proportions of Culex mosquitoes exiting and probably dying from starvation, relative to the situation in the West African huts

Selective activation of TCR-γδ+ cells in endemic Burkitt's lymphoma

<p>Abstract</p> <p>Background</p> <p>The overlap in geographical distribution of <it>Plasmodium falciparum </it>malaria and endemic Burkitt's lymphoma (eBL) – an aggressive Epstein-Barr virus (EBV)-associated B-cell tumour occurring almost exclusively in the tropics – strongly suggests a link between the two diseases. It is suspected that the polyclonal B-cell activation in <it>P. falciparum </it>malaria may precipitate a breakdown in homeostatic T-cell control of EBV-immortalized B-cell proliferation. Previous studies have suggested that a particular T-cell subset, characterized by expression of V<it>δ</it>1⁺<it>γδ </it>T-cell receptors, is important for maintaining B-cell homeostasis, both in <it>P. falciparum</it>- exposed populations and in individuals subject to polyclonal B-cell activation of other aetiology. The objective of the present study was, therefore, to characterize lymphocyte phenotypes and to investigate possible differences in T-cell subset composition and activation status in <it>P. falciparum</it>-exposed Ghanaian children with and without eBL.</p> <p>Methods</p> <p>Venous blood samples in heparin from 21 eBL patients (mean age: 7.0 years; range: 3–11 years), referred to the Burkitt's Tumour Centre at Korle-Bu Teaching Hospital, Accra and 15 healthy, age and sex matched children, were stained with fluorescein isothiocyanate (FITC)-, phycoerythrin (PE)-, R-phycoerythrin (RPE)- and RPE-Cy5-conjugated antibodies (CD3, CD4, CD8, CD25, CD69, CD95, HLA-DR, TCR-<it>γδ</it>, V<it>δ</it>1, V<it>δ</it>3, V<it>γ</it>9 and B-cells) and acquired on a flow cytometer.</p> <p>Results</p> <p>A reduction in the proportion of CD3⁺cells in eBL patients, due mainly to perturbations among TCR-<it>γδ</it>⁺cells was observed. In contrast, the proportions of CD4⁺or CD8⁺cells were relatively unaffected, as were the mean numbers of peripheral blood mononuclear cells.</p> <p>Conclusion</p> <p>Selective changes in numbers and activation status of TCR-<it>γδ</it>⁺cells occurs in Ghanaian children with eBL, a pattern which is similar to <it>P. falciparum</it>-induced changes.

Toward Better College Course Placement: A Guide to Launching a Multiple Measures Assessment System

Drawing on lessons from 10 Minnesota and Wisconsin colleges that piloted multiple measures systems for placing students into developmental and college-level courses, this guide from CCRC and MDRC provides recommendations for other colleges interested in implementing or testing their own multiple measures systems. Beginning with the rationale behind changing assessment practices, the guide outlines what a multiple measures assessment system is, what it takes to get started, the personnel involved, and the costs that may be incurred in the design and planning processes. Recent evidence suggests that relying on traditional placement tests misplaces substantial numbers of students, with many going into developmental education who could have been successful in college-level courses. Multiple measures placement systems that use alternative measures alongside the traditional tests will potentially provide more accurate results and better student outcomes. Still, practitioners may be hesitant to change their current practices, skeptical about the measures used, or unsure where to start. The information in this guide addresses these concerns and provides recommendations for how to approach each step of the implementation process

Indoor use of attractive toxic sugar bait in combination with long-lasting insecticidal net against pyrethroid-resistant Anopheles gambiae: an experimental hut trial in Mbé, central Côte d'Ivoire.

BACKGROUND: Indoor attractive toxic sugar bait (ATSB) has potential as a supplementary vector-control and resistance-management tool, offering an alternative mode of insecticide delivery to current core vector-control interventions, with potential to deliver novel insecticides. Given the high long-lasting insecticidal bed net (LLIN) coverage across Africa, it is crucial that the efficacy of indoor ATSB in combination with LLINs is established before it is considered for wider use in public health. METHODS: An experimental hut trial to evaluate the efficacy of indoor ATSB traps treated with 4% boric acid (BA ATSB) or 1% chlorfenapyr (CFP ATSB) in combination with untreated nets or LLINs (holed or intact), took place at the M'bé field station in central Côte d'Ivoire against pyrethroid resistant Anopheles gambiae sensu lato. RESULTS: The addition of ATSB to LLINs increased the mortality rates of wild pyrethroid-resistant An. gambiae from 19% with LLIN alone to 28% with added BA ATSB and to 39% with added CFP ATSB (p < 0.001). Anopheles gambiae mortality with combined ATSB and untreated net was similar to that of combined ATSB and LLIN regardless of which insecticide was used in the ATSB. The presence of holes in the LLIN did not significantly affect ATSB-induced An. gambiae mortality. Comparative tests against pyrethroid resistant and susceptible strains using oral application of ATSB treated with pyrethroid demonstrated 66% higher survival rate among pyrethroid-resistant mosquitoes. CONCLUSION: Indoor ATSB traps in combination with LLINs enhanced the control of pyrethroid-resistant An. gambiae. However, many host-seeking An. gambiae entering experimental huts with indoor ATSB exited into the verandah trap without sugar feeding when restricted from a host by a LLIN. Although ATSB has potential for making effective use of classes of insecticide otherwise unsuited to vector control, it does not exempt potential selection of resistance via this route

Empirical and theoretical investigation into the potential impacts of insecticide resistance on the effectiveness of insecticide-treated bed nets.

In spite of widespread insecticide resistance in vector mosquitoes throughout Africa, there is limited evidence that long-lasting insecticidal bed nets (LLINs) are failing to protect against malaria. Here, we showed that LLIN contact in the course of host-seeking resulted in higher mortality of resistant Anopheles spp. mosquitoes than predicted from standard laboratory exposures with the same net. We also found that sublethal contact with an LLIN caused a reduction in blood feeding and subsequent host-seeking success in multiple lines of resistant mosquitoes from the laboratory and the field. Using a transmission model, we showed that when these LLIN-related lethal and sublethal effects were accrued over mosquito lifetimes, they greatly reduced the impact of resistance on malaria transmission potential under conditions of high net coverage. If coverage falls, the epidemiological impact is far more pronounced. Similarly, if the intensity of resistance intensifies, the loss of malaria control increases nonlinearly. Our findings help explain why insecticide resistance has not yet led to wide-scale failure of LLINs, but reinforce the call for alternative control tools and informed resistance management strategies

Evaluation of standard pyrethroid based LNs (MiraNet and MagNet) in experimental huts against pyrethroid resistant Anopheles gambiae s.l. M'bé, Côte d'Ivoire: Potential for impact on vectorial capacity.

BACKGROUND: There is evidence from experimental hut and household studies that the entomological efficacy of long lasting pyrethroid treated nets (LLINs) is compromised in areas of pyrethroid resistance. The rapid increase in resistance intensity in African malaria vectors could further undermine the performance of these nets. The pyrethroid resistance intensity in Anopheles gambiae s.l. M'bé from central Côte d'Ivoire is reported to be high (> 1700 fold). Whether this translates into an increase in entomological indicators of malaria transmission needs investigation. METHOD: The efficacy of two long lasting insecticidal nets (LN) MiraNet and MagNet, both alpha-cypermethrin based was evaluated in experimental huts against pyrethroid resistant Anopheles gambiae in M'bé, central Côte d'Ivoire. All nets were deliberately holed to simulate wear-and-tear and were tested unwashed and after 20 standardized washes. RESULTS: The entry rates of An. gambiae s.l. into huts with insecticide treated nets were 62-84% lower than entry into huts with untreated nets (p < 0.001). Exit rates of An. gambiae s.l. with unwashed MiraNet and MagNet LNs were significantly greater than with untreated nets (50-60% vs 26%) and this effect after washing 20 times nets did not decrease. Blood-feeding with both nets was significantly inhibited relative to the untreated reference net (31-55%) (p < 0.001). Washing MiraNet LN 20 times had no significant impact on protection against An. gambiae s.l. bites but it did cause a significant fall by 40% in protection with MagNet LN (p < 0.001). All insecticide treated nets induced higher mortality of An. gambiae s.l. than the untreated net (p < 0.05). The impact though significant was limited (14-30%). The personal protection against An. gambiae s.l. bites derived from all treatments was high (75-90%). The overall insecticidal effect was compromised by pyrethroid resistance and was not detectable in some treatments. CONCLUSION: In this area of high pyrethroid resistance intensity (over 1700 fold), both MiraNet and MagNet LNs still conferred appreciable personal protection against mosquito bites despite inducing only slightly greater mortality of pyrethroid resistant Anopheles mosquitoes than untreated nets. The impact is comparable to moderately intense Benin resistance area (207 fold) and Burkina Faso (over 1000 fold). This preserved level of protection plus the small but sensitive killing of mosquitoes may continue to impact vectorial capacity despite high intensity of resistance. Nevertheless, there is an obvious need for strategies and nets with novel mode of action to enhance vector control

Evaluation of an alpha-cypermethrin + PBO mixture long-lasting insecticidal net VEERALIN® LN against pyrethroid resistant Anopheles gambiae s.s.: an experimental hut trial in M'bé, central Côte d'Ivoire.

BACKGROUND: Long-lasting insecticidal nets (LLINs) are the primary method of malaria prevention. However, the widespread resistance to pyrethroids among major malaria vector species represents a significant threat to the continued efficacy of pyrethroid LLIN. Piperonyl butoxide (PBO) is a synergist that inhibits the activity of metabolic enzymes of the cytochrome P450 family known to detoxify insecticides including pyrethroids. Synergist LLIN incorporating PBO and a pyrethroid may provide improved control compared to pyrethroid-only LLIN. METHODS: The efficacy of VEERALIN® LN (VKA polymers Pvt Ltd, India), an alpha-cypermethrin PBO synergist net was evaluated in experimental huts in M'bé, central Côte d'Ivoire against wild pyrethroid resistant Anopheles gambiae s.s. Comparison was made with a standard alpha-cypermethrin-treated net (MAGNet® LN, VKA polymers Pvt Ltd, India). Nets were tested unwashed and after 20 standardized washes. RESULTS: VEERALIN® LN demonstrated improved efficacy compared to MAGNet® LN against wild free-flying pyrethroid-resistant An. gambiae s.s. Before washing, VEERALIN® LN produced mortality of An. gambiae s.s. (51%) significantly higher than the standard pyrethroid-only net (29%) (P < 0.0001). Although there was a significant reduction in mortality with both LLINs after 20 washes, VEERALIN® LN remained superior in efficacy to MAGNet® LN (38 vs 17%) (P < 0.0001). Blood-feeding was significantly inhibited with both types of insecticide-treated nets relative to the untreated control net (P < 0.0001). Unwashed VEERALIN® LN induced significantly higher blood-feeding inhibition of An. gambiae s.s. (62.6%) compared to MAGNet® LN (35.4%) (P < 0.001). The difference persisted after washing, as there was no indication that either LLIN lost protection against biting or blood-feeding. The level of personal protection derived from the use of VEERALIN® LN was high (87%) compared to MAGNet® LN (66-69%) whether unwashed or washed. The AI content of VEERALIN® LN after 20 washes decreased from 6.75 to 6.03 g/kg for alpha-cypermethrin and from 2.95 to 2.64 g/kg for PBO, corresponding to an overall retention of 89% for each compound. CONCLUSIONS: The addition of the synergist PBO to pyrethroid net greatly improved protection and control of pyrethroid-resistant An. gambiae s.s. The pyrethroid-PBO VEERALIN® LN has the potential to reduce transmission in areas compromised by pyrethroid resistance
