Survey reveals slow strides in promoting adolescent reproductive health in Vietnam

This article presents the findings of a survey evaluating the adolescent reproductive health program by the Vietnamese Government. Conducted by the Population Research Consultants, survey findings revealed several setbacks of the adolescent reproductive health program; these included the following: 1) adolescents favor radio, television and newspapers as sources of reproductive health (RH) information; 2) adolescents have no knowledge of pregnancy, sexually transmitted diseases, and HIV/AIDS prevention; 3) the demand for RH information varies according to the sociodemographic characteristics of respondents; 4) while the majority of adolescents do not favor premarital sex and premarital pregnancy, their choice is to keep and deliver the baby in case of a premarital pregnancy; 5) adolescents give a poor rating to the quality of RH/family planning services at the centers; 6) adolescents need to further understand RH but not knowing its meaning, they cannot tell what type of information they require; 6) adolescents have poor knowledge of adolescent reproductive health; 7) friendship and love are often discussed among adolescents, but sexuality rarely is; and 8) adolescents have poor knowledge of RH and poor interest in RH/family planning service facilities.     

Educating force multipliers: constructing terrorism in a US public high school

ABSTRACT

This article ethnographically explores a specialized Homeland Security program at a US public high school, paying careful attention to the program’s discursive constructions of terrorism and national security. In particular, this analysis examines how the Homeland Security program framed its study of national security as both anti-racist and objective. I contend that the invocation of anti-racism and objectivity can advance Orientalist discourses in the classroom. Critical education scholars need to address how teachers and students rely on liberal precepts like anti-racism to maintain dominant understandings of war, terror, and security.     

Examining the Effects of Changes in Classroom Quality on Within-Child Changes in Achievement and Behavioral Outcomes

This study examines whether changes in classroom quality predict within-child changes in achievement and behavioral problems in elementary school (ages spanning approximately 6–11 years old). Drawing on data from a longitudinal study of children in predominantly low-income, nonurban communities (n = 1,078), we relied on child fixed effects modeling, which controlled for stable factors that could bias the effects of classroom quality. In general, we found that changes in classroom quality had small and statistically nonsignificant effects on achievement and behavior. However, we found that moving into a high-quality classroom, particularly those rated as high in Classroom Organization, had positive effects on achievement and behavior for children with significant exposure to poverty in early life.     

Waiting to decide helps in the face of probabilistic uncertainty but not delay uncertainty

A first-person shooter video game was adapted for the study of causal decision making within dynamic environments. Participants chose which of three potential targets in each of 21 groups was producing distal explosions. The source of the explosion effect varied in the delay between the firing of its weapon and its effect (0.0, 0.5, 1.0, and 2.0 s), the probability that the weapon caused the effect (50%, 75%, and 100%), and the occurrence of auditory events that filled the delay. In Experiment 1, participants’ choice accuracy was highest with short delays but was not affected by probability; participants often compensated for lower probability by increasing their latencies, and thus the number of outcomes sampled. In Experiment 2, a broad range of delays (0–2 s) and probabilities (20%–100%) were randomly sampled for each cause; the results largely replicated those of the prior experiment. The experiments demonstrate people’s ability to successfully modulate their environmental sampling in the face of uncertainty due to lower cause–effect probabilities, but not in the presence of longer cause–effect delays.     

The irony of rigor: ‘no-excuses’ charter schools at the intersections of race and disability

Across the United States, the ‘no-excuses’ charter school movement featuring strict discipline policies and rigorous academic standards has gained popularity among schools serving poor and working-class students of color. In this article, we examine how Black and Latinx parents of students with disabilities¹ negotiated and experienced these charter school practices of rigor, which disciplined, managed, and regulated students’ social differences. Drawing from a yearlong qualitative research study, we examine interviews with Black and Latinx parents who experienced conflict with charter schools and the school lawyers, along with school artifacts we gathered such as parent handbooks and website information. We found parents experienced what we refer to as the ‘irony of rigor:’ the contradictory double-movement through which students of color with disabilities desired inclusion into ‘rigorous’ charter schools which then excluded them using ‘rigor’ as a central feature of student pushout practices. We present the irony of rigor in three interrelated acts: Act I: the lure of rigor (i.e. what drew parents to charter schools); Act II: the body meets rigor (i.e. how schools disciplined and managed student differences); and Act III: the consequences of rigor (i.e., what happened to students and parents while and after experiencing rigorous practices). We contextualize the irony of rigor within the relationship between disability, race, and neoliberalism.     

Effect of slippage on the thermocapillary migration of a small droplet

We conduct a numerical investigation and analytical analysis of the effect of slippage on the thermocapillary migration of a small liquid droplet on a horizontal solid surface. The finite element method is employed to solve the Navier-Stokes equations coupled with the energy equation. The effect of the slip behavior on the droplet migration is determined by using the Navier slip condition at the solid-liquid boundary. The results indicate that the dynamic contact angles and the contact angle hysteresis of the droplet are strictly correlated to the slip coefficient. The enhancement of the slip length leads to an increase in the droplet migration velocity due to the enhancement of the net momentum of thermocapillary convection vortices inside the droplet. A larger contact angle leads to an increase in the migration velocity which in turn enlarges the rate of the droplet migration velocity to the slip length. There is good agreement between the analytical and the numerical results when the dynamic contact angle utilizes in the analytical approach obtained from the results of the numerical computation, and the static contact angle is smaller than 50°.     

Cooperative learning that features a culturally appropriate pedagogy

Many recent intercultural studies have shown that people cooperate with each other differently across cultures. We argue that cooperative learning (CL), an educational method originating in the USA and with fundamental psychological assumptions based on Western values, should be adjusted to be culturally appropriate for any non‐Western cultures in which it is applied. In the light of this assertion, this paper reports a series of experiments conducted in Vietnamese upper‐secondary schools. One group was provided with a series of lessons designed according to mainstream CL practice. Another group was provided with similar lessons but these were modified so as to be more culturally appropriate in terms of leadership, reward allocation and group composition. Findings show that (1) the role and the type of leadership, although not a key element of mainstream CL theories and practice, proved to be influential; (2) groupings based upon existing friendships, rather than upon cognitive ability, appeared to be important. A key finding was that the group receiving a culturally modified programme appeared to work harder during, and gain more satisfaction from, collaborative learning activities.
