Sites of Conversation

Through our lives we sit at many tables, eating, preparing food, playing, making drawings, doing homework, working and more. In other words, the table is a focal point where words and materials meet, cross each-other, collide or come together. The table can take us to a space and time where forgotten memories emerge and embodied actions are found. The Phenomenology and Imagination Research Group (PIRG) is an independent research group whose aim is to develop research through active fine art collective practice. PIRG’s Table Method (tm) is a process that has grown organically over a period of five years and has been cultivated through a desire to bring words, texts, actions and materials together as it invites participants to respond to a text through conversation, the handling of materials and tools.  The work draws from the new materialist turn through the ideas of Gaston Bachelard, Maurice Merleau-Ponty, Karen Barad and Jane Bennett.  PIRG has extended its practice of conversation as a research methodology to include the phenomenological and material interaction that has become the tm. The tm is an unfolding dialogue between materials and phenomenological thinking, which expands the possibilities of what conversation can be and become, it utilises material thinking as a way to open out discourse beyond the constraints of language and other representations

Evaluation of Residual Chlorothalonil Levels on Processing Tomato Foliage Using the TOM-CAST Spray Program

Field tomatoes were sprayed with chlorothalonil on a fixed–interval spray program and a TOM–CAST spray program with disease severity value threshold of 18. Foliage samples from upper and lower canopy layers were collected prior to spray re–applications. Chlorothalonil residue data were compared to the chlorothalonil efficacy threshold (1.2 μg/cm2). Using a seven–day interval program, eight of the nine and seven of the nine spray intervals had chlorothalonil residues above the critical level for the upper and lower canopy layers, respectively. Using the TOM–CAST program, four of the five spray intervals had chlorothalonil residues above the critical level for both upper and lower canopy layers when the DSV threshold of 18 was reached. Persistence of chlorothalonil residues at effective concentrations could lengthen the spray interval beyond the DSV–based spray recommendation

Long distance decoy state quantum key distribution in optical fiber

The theoretical existence of photon-number-splitting attacks creates a security loophole for most quantum key distribution (QKD) demonstrations that use a highly attenuated laser source. Using ultra-low-noise, high-efficiency transition-edge sensor photodetectors, we have implemented the first version of a decoy-state protocol that incorporates finite statistics without the use of Gaussian approximations in a one-way QKD system, enabling the creation of secure keys immune to photon-number-splitting attacks and highly resistant to Trojan horse attacks over 107 km of optical fiber.Comment: 4 pages, 3 figure

Ankyrin-B Syndrome: Enhanced Cardiac Function Balanced by Risk of Cardiac Death and Premature Senescence

Here we report the unexpected finding that specific human ANK2 variants represent a new example of balanced human variants. The prevalence of certain ANK2 (encodes ankyrin-B) variants range from 2 percent of European individuals to 8 percent in individuals from West Africa. Ankyrin-B variants associated with severe human arrhythmia phenotypes (eg E1425G, V1516D, R1788W) were rare in the general population. Variants associated with less severe clinical and in vitro phenotypes were unexpectedly common. Studies with the ankyrin-B+/− mouse reveal both benefits of enhanced cardiac contractility, as well as costs in earlier senescence and reduced lifespan. Together these findings suggest a constellation of traits that we term “ankyrin-B syndrome”, which may contribute to both aging-related disorders and enhanced cardiac function

Quantum entanglement and Bell violation of two coupled cavity fields in dissipative environment

We study the quantum entanglement between two coupled cavities, in which one is initially prepared in a mesoscopic superposition state and the other is in the vacuum in dissipative environment and show how the entanglement between two cavities can arise in the dissipative environment. The dynamic behavior of the nonlocality for the system is also investigated.Comment: 12 pages, 5 figure

The Role of Discrete Emotions in Job Satisfaction: A Meta-Analysis

[Summary] The relationship between emotions and job satisfaction is widely acknowledged via affective events theory (AET). Despite its widespread use, AET was not designed to address why specific emotions might differentially relate to job satisfaction. We utilize appraisal theory of emotion to refine AET and provide this nuanced theorizing. We meta‐analytically test our ideas with 235 samples across 99 883 individuals and 22 600 intra‐individual episodes. We test two approaches—specific emotion experiences (16 discrete emotions) versus general emotion experiences (positive or negative emotions)—and present empirical evidence of their similarities and differences with job satisfaction. Our findings suggest that specific emotions with circumstance‐agency appraisals (e.g., depression and happiness) have the strongest associations with job satisfaction compared to emotions with self‐ and other‐agency appraisals and general emotion experiences. However, more variability is observed for negative emotions and job satisfaction compared to positive emotions. Further, we address and even challenge influential critiques of emotions and job satisfaction via a meta‐analytic test of five moderators—emotion intensity versus frequency, target of emotion, job satisfaction measure, level of analysis, and time referent for emotion and job satisfaction recall. In sum, we advance academic and practitioner understanding of the relationship between emotions and job satisfaction

Analyzing Recent Coronary Heart Disease Mortality Trends in Tunisia between 1997 and 2009.

BACKGROUND: In Tunisia, Cardiovascular Diseases are the leading causes of death (30%), 70% of those are coronary heart disease (CHD) deaths and population studies have demonstrated that major risk factor levels are increasing. OBJECTIVE: To explain recent CHD trends in Tunisia between 1997 and 2009. METHODS: DATA SOURCES: Published and unpublished data were identified by extensive searches, complemented with specifically designed surveys. ANALYSIS: Data were integrated and analyzed using the previously validated IMPACT CHD policy model. Data items included: (i)number of CHD patients in specific groups (including acute coronary syndromes, congestive heart failure and chronic angina)(ii) uptake of specific medical and surgical treatments, and(iii) population trends in major cardiovascular risk factors (smoking, total cholesterol, systolic blood pressure (SBP), body mass index (BMI), diabetes and physical inactivity). RESULTS: CHD mortality rates increased by 11.8% for men and 23.8% for women, resulting in 680 additional CHD deaths in 2009 compared with the 1997 baseline, after adjusting for population change. Almost all (98%) of this rise was explained by risk factor increases, though men and women differed. A large rise in total cholesterol level in men (0.73 mmol/L) generated 440 additional deaths. In women, a fall (-0.43 mmol/L), apparently avoided about 95 deaths. For SBP a rise in men (4 mmHg) generated 270 additional deaths. In women, a 2 mmHg fall avoided 65 deaths. BMI and diabetes increased substantially resulting respectively in 105 and 75 additional deaths. Increased treatment uptake prevented about 450 deaths in 2009. The most important contributions came from secondary prevention following Acute Myocardial Infarction (AMI) (95 fewer deaths), initial AMI treatments (90), antihypertensive medications (80) and unstable angina (75). CONCLUSIONS: Recent trends in CHD mortality mainly reflected increases in major modifiable risk factors, notably SBP and cholesterol, BMI and diabetes. Current prevention strategies are mainly focused on treatments but should become more comprehensive

Trade-offs between immunity and testosterone in male African ground squirrels

The immunocompetence handicap hypothesis (ICHH) proposes that testosterone has both beneficial effects on male reproductive potential and negative effects by suppressing the immune system. However, support for the ICHH has been variable and an alternative hypothesis suggests that testosterone may be acting indirectly via cortisol to suppress immunity (the stress-linked ICHH). A third hypothesis is that increased energetic investment in immunity results in the suppression of testosterone. We tested these hypotheses in male Cape ground squirrels (Xerus inauris) through two separate manipulations; first by triggering a strong immune response using a lipopolysaccharide (LPS) injection and secondly by increasing circulating testosterone using silastic testosterone implants. Responding to an immune challenge significantly reduced testosterone, supporting the immunity suppression hypothesis, while increasing circulating testosterone had no effect on immunocompetence, body mass, ectoparasite abundances or cortisol levels, failing to support either the ICHH or stress-linked ICHH. Our results add to the increasing body of literature that challenges the ICHH, and we conclude that the trade-off between testosterone and immunity is mediated through immune activation and not through testosterone in male Cape ground squirrels. Being able to test the ICHH, stress-linked ICHH and immune suppression hypotheses in a free ranging mammal gives us a unique opportunity to examine the mechanisms mediating this trade-off.A Natural Sciences and Engineering Research Council of Canada Discovery grant (#04362), Canadian Foundation of Innovation (#27125), and a University of Manitoba Faculty of Science Field Work Support grant awarded to JMW, a Natural Sciences and Engineering Research Council of Canada Discovery grant (#311909) awarded to WGA, SARChI chair (# 64756) from the Department of Science and Technology and National Research Foundation, RSA awarded to NCB and awards from the University of Manitoba (Barrett- Hamilton Award; Faculty of Science) to KAO.http://jeb.biologists.org2019-08-23am2018Mammal Research InstituteZoology and Entomolog

Comparative case studies in integrated care implementation from across the globe : a quest for action

The case studies represent integrated care implementation efforts from five countries and continents (United States, United Kingdom, Vietnam, Israel, and Nigeria), targeting a range of clinical populations and care settings. The study addresses two research objectives: 1) To highlight current integrated care implementation efforts that target a range of healthcare systems, patient populations and implementation strategies and outcomes, and 2) To synthesize the shared and unique challenges and successes across studies using the Exploration, Preparation, Implementation, Sustainment (EPIS) framework.
