Actual and symbolic prisons, Black men, and the freedom-unfreedom paradox: interrogating the bad faith of racialized oppression in a post-accountable United States.

Drawing on systemic racism theory, white racial framing and the notion of bad faith as the connecting, justifying thread between ideals of freedom and equality and actions realizing unfreedom and inequities, this essay explores the alchemy of race, masculinity, and racialized oppression and its consequences for Black men past and present in United States society. This essay's aim is to trace the historical ideologies and cultural practices, relations, and normative standards that have contributed to, and hence must be challenged to confront, the inequitable, race-based relations of power, and privilege at the root of institutionalized injustices. To do so, this essay interrogates the dissonance of bad faith as a corrective mode of truth telling to highlight and tap the equity potential of Black men's collective, historical rejections of the White mainstream's conflicting definitions and deceptive reasonings requisite for pushing toward racial justice, healing, and peace.

Effect of Nonselective His Bundle Pacing on Delayed Myocardial Activation in Left-axis Deviation and Left Bundle Branch Block.

It has been suggested that nonselective His bundle pacing (NS-HBP) corrects terminal conduction delay in right bundle branch block by early excitation of the right ventricular free wall. A similar analysis of NS-HBP, in patients with left bundle branch block (LBBB) and left-axis deviation (LAD) has not been done. Therefore, we compared the baseline QRS parameters in LAD and LBBB during NS-HBP and selective HBP (S-HBP).

The efficacy of spinosad against the western flower thrips, Frankliniella occidentalis, and its impact on associated biological control agents on greenhouse cucumbers in southern Ontario.

Insecticides are the most commonly used tactic to control western flower thrips (WFT), Frankliniella occidentalis Pergande (Thysanoptera: Thripidae), on greenhouse cucumber. However, WFT has developed resistance to several of the insecticides presently in use. In addition, some of these insecticides adversely affect greenhouse biological control agents used to control WFT, resulting in subsequent pest resurgence.

Laboratory evaluation of two novel strategies to control first-instar gypsy moth larvae with spinosad applied to tree trunks.

Two strategies for controlling first-instar larvae of gypsy moth (Lymantria dispar (L)), insecticidal bait and contact insecticide applied directly to the tree trunk, were evaluated in the laboratory. Spinosad was selected as a candidate natural-product insecticide that is active both by contact and ingestion. Incorporated into artificial diet-based bait, spinosad was toxic to neonate larvae with a minimal 10-s feeding period, with an LC50 value of 20 (15-26, 95% confidence interval) mg liter-1.

Fate of spinosad in litter and soils of a white spruce plantation in central Ontario.

Spinosad is a natural insecticide with potential as a novel biorational control agent for spruce budworm (Choristoneura fumiferana [Clem]), the most destructive insect defoliator of spruce and balsam fir in Canada. Concurrent terrestrial fate experiments were conducted under full coniferous canopy and in a natural opening of a mature white spruce (Piecea glauca [Moench]) plantation of central Ontario to examine the fate and persistence of spinosad in the forest floor and underlying soils. Mean initial residues of spinosyn A and D were approximately 0.

Fate of spinosad in litter and soils of a mixed conifer stand in the Acadian forest region of New Brunswick.

Spinosad is a natural insecticide, produced via fermentation culture of the actinomycete Saccharopolyspora spinosa, with potential use against a number of forest pests including spruce budworm (Choristoneura fumiferana [Clem]). Persistence of spinosad was determined in terrestrial fate experiments conducted within a semimature stand of black spruce (Picea mariana [Mill.]) and balsam fir (Abies balsamea [L]) in the Acadian forest region of New Brunswick, Canada.
