A Common Path: Navigating Your Way to Successful Negotiations in the Workplace
[Excerpt] Creating change in the workplace can be a difficult process, especially if it requires asking for job accommodations from your supervisor or boss. For many, requesting assistance can feel like an intimidating task. If an individual has decided not to disclose his or her disability or significant health issue to an employer, this situation may feel even more difficult. Yet often times accommodations are necessary to create a comfortable and effective working environment. The good news is that this interaction between employee and boss is not nearly as scary as it can appear to be. It can be, in fact, a very rewarding and empowering experience. With this in mind, “Working it Out Together” held an exciting seminar with three expert panelists. These guest speakers presented on a variety of tools and tips aimed at creating win-win situations.d
Ability, Parental Valuation of Education and the High School Dropout Decision
We use a large, rich Canadian micro-level dataset to examine the channels through which family socio-economic status and unobservable characteristics affect children's decisions to drop out of high school. First, we document the strength of observable socio-economic factors: our data suggest that teenage boys with two parents who are themselves high school dropouts have a 16% chance of dropping out, compared to a dropout rate of less than 1% for boys whose parents both have a university degree. We examine the channels through which this socio-economic gradient arises using an extended version of the factor model set out in Carneiro, Hansen, and Heckman (2003). Specifically, we consider the impact of cognitive and non-cognitive ability and the value that parents place on education. Our results support three main conclusions. First, cognitive ability at age 15 has a substantial impact on dropping out. Second, parental valuation of education has an impact of approximately the same size as cognitive ability effects for medium and low ability teenagers. A low ability teenager has a probability of dropping out of approximately .03 if his parents place a high value on education but .36 if their education valuation is low. Third, parental education has no direct effect on dropping out once we control for ability and parental valuation of education. Our results point to the importance of whatever determines ability at age 15 (including, potentially, early childhood interventions) and of parental valuation of education during the teenage years. We also make a small methodological contribution by extending the standard factor based estimator to allow a non-linear relationship between the factors and a covariate of interest. We show that allowing for non-linearities has a substantial impact on estimated effects.Idiosyncratic Shocks, Disability, Insurance, Marriage
Ability, parental valuation of education and the high school dropout decision
We use a large, rich Canadian micro-level dataset to examine the channels through which family socio-economic status and unobservable characteristics affect children's decisions to drop out of high school. First, we document the strength of observable socio-economic factors: our data suggest that teenage boys with two parents who are themselves high school dropouts have a 16 per cent chance of dropping out, compared to a dropout rate of less than 1 per cent for boys whose parents both have a university degree. We examine the channels through which this socio-economic gradient arises using an extended version of the factor model set out in Carneiro, Hansen, and Heckman (2003). Specifically, we consider the impact of cognitive and non-cognitive ability and the value that parents place on education. Our results support three main conclusions. First, cognitive ability at age 15 has a substantial impact on dropping out. The highest ability individuals are predicted never to drop out regardless of parental education or parental valuation of education. In contrast, the lowest ability teenagers have a probability of dropping out of approximately .36 if their parents have a low valuation of education. Second, parental valuation of education has a substantial impact on medium and low ability teenagers. A low ability teenager has a probability of dropping out of approximately .03 if his parents place a high value on education but .36 if their educational valuation is low. These effects are estimated while conditioning on ability at age 15. Thus, under some assumptions, they reflect parental influences during the upper teenage years and are in addition to any impact they might have in the early childhood years leading up to age 15. Third, parental education has no direct effect on dropping out once we control for ability and parental valuation of education. Overall, our results point to the importance of whatever determines ability at age 15 (including, potentially, early childhood interventions) and of parental valuation of education during the teenage years. Our work also provides a small methodological contribution by extending the standard factor based estimator to allow a more non-linear relationship between the factors and a co-variate of interest. We show that allowing for non-linearities has a substantial impact on estimated effects.
The effects of pre- and postnatal administration of propionic acid and lipopolysaccharide on the behaviour of adolescent male and female rats
The gut microbiome plays an important role in immune functioning and neurodevelopment. Altered microbiome composition, leading to short chain fatty acid, and/or immune system dysfunction has been observed in children with autism spectrum disorders (ASD). This thesis describes the developmental influence of prenatal exposure to propionic acid (PPA), a metabolic fermentation product of enteric bacteria, or prenatal exposure to lipopolysaccharide (LPS), a bacterial mimetic and product of enteric bacteria, on a range of behaviours in male and female neonatal, adolescent and adult rats. Study one evaluated the effects of prenatal PPA and LPS, and postnatal PPA, on developmental milestones in early life and on subsequent locomotor activity and anxiety-related behaviours. Study two examined acoustic startle response (ASR) and prepulse inhibition, while the third examined social behaviours. Overall, prenatal and postnatal treatments subtly altered behaviour in a sex- and test-specific manner. Male and female rats showed developmental delay in the day of eye opening and in acquiring a nest seeking odor discrimination. Prenatal and postnatal PPA treatments increased anxiety-related behaviour and altered ASR. Male rats displayed alterations in social behaviour and locomotor activity that was not observed in female rats, supporting the male bias seen in autism. However, female rats also showed augmented sensitivity to PPA, displaying repetitive behaviour, altered ASR, and decreased prepulse inhibition, in agreement with the evidence that these behaviours are more severe in females with ASD. Together, these findings demonstrate that the metabolic products of enteric bacteria, PPA and LPS, may alter development in ways resembling ASD
The Relation Between Ejecta Velocity, Intrinsic Color, and Host-Galaxy Mass for High-Redshift Type Ia Supernovae
Recently, using a large low-redshift sample of Type Ia supernovae (SNe Ia),
we discovered a relation between SN Ia ejecta velocity and intrinsic color that
improves the distance precision of SNe Ia and reduces potential systematic
biases related to dust reddening. No SN Ia cosmological results have yet made a
correction for the "velocity-color" relation. To test the existence of such a
relation and constrain its properties at high redshift, we examine a sample of
75 SNe Ia discovered and observed by the Sloan Digital Sky Survey-II (SDSS-II)
Supernova Survey and Supernova Legacy Survey (SNLS). From each spectrum, we
measure ejecta velocities at maximum brightness for the Ca H&K and Si II 6355
features, v_Ca^0 and v_Si^0, respectively. Using SN light-curve parameters, we
determine the intrinsic B_max - V_max for each SN. Similar to what was found at
low-redshift, we find that SNe Ia with higher ejecta velocity tend to be
intrinsically redder than SNe Ia with lower ejecta velocity. The distributions
of ejecta velocities for SNe Ia at low and high redshift are similar,
indicating that current cosmological results should have little bias related to
the velocity-color relation. Additionally, we find a slight (2.4-sigma
significant) trend between SN Ia ejecta velocity and host-galaxy mass such that
SNe Ia in high-mass host galaxies tend to have lower ejecta velocities as
probed by v_Ca^0. These results emphasize the importance of spectroscopy for SN
Ia cosmology.Comment: 13 pages, 11 figures, accepted by Ap

Are Two Carrots Better Than One? The Effects of Adding Employment Services to Financial Incentive Programs for Welfare Recipients
The Self-Sufficiency Project (SSP) was a social experiment conducted in two provinces in Canada during the 1990s that tested a generous financial incentive program for welfare recipients. A little-known subsidiary experiment, called SSP Plus, had a three-way design that tested the incremental effect of adding employment services to the generous financial incentive program. Employment services are viewed by many welfare analysts as an important component of an overall strategy for helping welfare recipients escape poverty and achieve stable employment. This paper presents the results of the SSP Plus experiment. Adding employment services encouraged more people to take up the earnings supplement, and it appeared to have long-term effects on full-time employment and welfare receipt. This might be because the services improved the jobs people obtained. Both earnings and wage rates were higher compared to earnings and wages without the services and the jobs held appeared to be more sustainable.Labor supply, social program evaluation, welfare policy
Ischemic preconditioning modulates ROS to confer protection in liver ischemia and reperfusion
Ischemia reperfusion (IR) injury is a significant cause of morbidity and mortality in liver transplantation. When
oxygen is reintroduced to the liver graft it initiates a cascade of molecular reactions leading to the release of reactive oxygen species (ROS) and pro-inflammatory cytokines. These soluble mediators propagate a sterile immune response to cause significant tissue damage. Ischemic preconditioning (IPC) is one method that reduces hepatocellular injury by altering the immune response and inhibiting the production of ROS. Studies quantifying the effects of IPC in humans have demonstrated an improved liver enzyme panel in patients receiving grafts pretreated with IPC as compared to patients receiving the standard of care. In our review, we explore current literature in the field in order to describe the mechanism through which IPC regulates the production of ROS and improves IR injury
Case Studies of Emerging/Innovative Vocational Rehabilitation Agency Practices in Improving Employment Outcomes for Individuals with Intellectual/Developmental Disabilities
The Vocational Rehabilitation Research and Training Center (VR-RRTC.org) based at the Institute for Community Inclusion (ICI) at the University of Massachusetts Boston partnered with national content experts to identify promising VR employment practices serving people with intellectual and/or developmental disabilities (IDD). The National Institute on Disability and Rehabilitation Research (NIDRR), the funding agency,requested an emphasis on identifying promising practices for people with mental illnesses and peoplewith intellectual disabilities/developmental disabilities, and to identify promising practices related to order of selection and the designation of most significant disability. This report provides a summary of four promising VR employment practices for persons with IDD. The study included a nationwide call for nominations through extensive outreach using a variety of channels and venues, including (but not limited to) direct contact with VR agencies, Technical Assistance and Continuing Education (TACE) Centers, the Council of State Administrators of Vocational Rehabilitation (CSAVR), the Rehabilitation Services Administration (RSA), and NIDRR. The VR RRTC formed a Delphi expert panel to review and rateall nominated practices using a systematic, multi-step procedure to evaluate nominations
