How minimum wages affect schooling-employment outcomes in Canada, 1993–1999

Based on longitudinal data from the Master File of the Survey of Labour and Income Dynamics (SLID) for Canada for 1993-1999, we provide multinomial logit estimates of the effect of minimum wages on the probability of being in one of four schooling-employment states as well as transitions across the states. We find that minimum wage increases led to large and statistically significant reductions in the employment of teenagers but had no net effect on their school enrollment or on the individual transition probabilities. We also find no substantial substitution of students for nonstudents or students leaving school to queue for the higher minimum wage jobs.     

Talking about Work: I used to talk about nothing else, I was excited and it got a bit too much for my parents

People with learning difficulties who had access to day services were invited to talk about their work placement or employment. Focus groups were used to gather information on type of work placement opportunities and the participants' experiences. The majority liked their job as it offered purposeful activity and opportunities to meet people. Many individuals wished to increase the number of hours worked, but several were relatively dissatisfied with their wages and negative interactions with workmates. The study identified that in spite of high motivation to work many individuals were unclear about their future occupational prospects. They did not have many opportunities to systematically explore and discuss their work related interests, range of placement options and how they could be accessed. Participants had not been involved in the search for their current placements. These omissions could result in increased reliance on day centres even for skilled individuals who might otherwise be employed in community settings.     

Optimal Sequencing of Unpunctual Patients in High‐Service‐Level Clinics

Even though patients often arrive early and out of turn for scheduled appointments in outpatient clinics, no research has been undertaken to establish whether an available provider should see an early patient right away (preempt) or wait for the patient scheduled next. This problem, which we call the “Wait‐Preempt Dilemma,” is particularly relevant for “high‐service‐level” clinics (such as psychotherapy, chiropractic, acupuncture), where preempting may cause the missing patient to wait for an excessively long time, should she show up soon. Typically, the dilemma is resolved by preemption, where the provider starts serving the patient who has already arrived to avoid staying idle. By contrast, we analytically determine the time intervals where it is optimal to preempt and those where it is optimal to wait, and find that in some cases the provider should in fact stay idle, even in the presence of waiting patients. Our results suggest that the proposed analytical method outperforms the always‐preempt policy in clinics that do not overbook and have service times longer than 30 minutes. In these cases, the analytical method dramatically reduces patient waiting times at the cost of a modest increase in overtime. By contrast, in clinics that overbook or have short service times, the two policies perform similarly, and hence the always‐preempt policy is preferable due to its simplicity. A software application is provided that clinics can readily use to solve the wait‐preempt dilemma.     

Young men's perspectives on family support and disclosure of same-sex attraction

Young men who have sex with men (YMSM) face myriad challenges when deciding to disclose their sexual orientation to family members. Key to this decision is consideration of how disclosure may influence the support they receive from family. This paper explores a diverse sample of YMSM's (N = 43) perspectives on disclosure of their same-sex attractions to key family members and its impact on family support. Several stages/categories of disclosure are described and some YMSM seemed to continue to move between categories. Additionally, relationships after disclosure included negotiations between the expression of their sexual orientation and the maintenance of family support.     

Dimensions of Social Status in Preadolescent Peer Groups: Likability, Perceived Popularity, and Social Dominance

A multidimensional, interdisciplinary model of social status was developed and examined in a sample of 487 fourth, fifth, and sixth grade elementary school students. Participants were clustered into seven subtypes (i.e., High Status, Perceived Popular/Dominant, Well‐Liked/Dominant, Average, Low Dominant/Unpopular, Disliked, and Low Status) based on the dimensions of likability, perceived popularity, and social dominance emphasized, respectively, by psychologists working within the sociometric tradition, sociologists of education, and ethologists. The meaningfulness of the cluster solution was supported by cluster differences on peer‐reported social prerogatives of status (e.g., admiration, social control, leadership) and self‐reported social characteristics. Furthermore, each cluster had a distinct behavioral profile. It was argued that a broader, multidisciplinary conceptualization of social status should lead to a better understanding of the complex dynamics present in children's peer groups in middle childhood as well as the tools preadolescents need to successfully navigate the peer system.     

Pregnancy wantedness and the early initiation of prenatal care

The study examines the impact of the wantedness of a pregnancy on the demand for early prenatal care. Using a cohort of pregnant women in New York City, we estimate a prenatal care demand function in which we control for the probability of giving birth, given a woman is pregnant. We interpret this control as a measure of wantedness. The results indicate that if the black and Hispanic women who aborted had instead given birth, they would have delayed the initiation of prenatal care, on average, more than three-quarters of a month longer than the mean number of months of delay that were actually observed for the women who gave birth. By allowing women to terminate an unwanted pregnancy, induced abortion increases the average use of prenatal care among black and Hispanic women relative to what would have been observed if the women who aborted had instead given birth.     

A Structured Literature Review for Risk Assessment: EMF and Human Health Risk

The volume of publications on any given topic makes it difficult to select an appropriate subset of publications for review by an expert panel. This paper proposes a method for selecting a subset using a protocol that attempts to order publications based upon good research methods. The protocol was followed by graduate students with no expert knowledge of the area they were reviewing. They reduced 11730 articles on the topic of EMF and Health risk to 68 articles that were reviewed by an expert panel. The interrater reliability was 96% and 94% of the relevant articles were captured by this process.
