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

Young ME  Sutherland SC  Cole JJ  Nguyen N 《Learning & behavior》2011,39(2):115-124

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.  相似文献

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

Federico R. Waitoller  Nicole Nguyen  Gia Super 《International journal of qualitative studies in education》2019,32(3):282-298

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.  相似文献

Effect of slippage on the thermocapillary migration of a small droplet     

Nguyen HB  Chen JC 《Biomicrofluidics》2012,6(1):12809-1280913

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°.  相似文献   

Cooperative learning that features a culturally appropriate pedagogy     

Nguyen Phuong‐Mai  Cees Terlouw  Albert Pilot  Julian Elliott 《British Educational Research Journal》2009,35(6):857-875

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.  相似文献

Linking versus searching: A case study of performance support use     

Frank Nguyen  Matthew Hanzel 《Performance Improvement》2007,46(10):40-44

In highly competitive global organizations, the practice of hit‐and‐miss searching for information is a luxury seldom afforded. This article examines a case study of an organization that explored the use of different types of performance support interventions for four years. Results show that performance support systems that link to relevant support content were used significantly more than systems that required the performer to search for and locate information. A comparison of these findings with the existing literature and the implications of these results for performance technologists are discussed.  相似文献   

A case analysis of ICT for knowledge transfer in small businesses in Vietnam     

Toan Nguyen  Stephen Burgess 《International Journal of Information Management》2014

Small businesses face numerous issues in regard to the management of their knowledge, including potential loss of knowledge due to high employee turnover and the willingness and ability of employees to share their knowledge. This case study examines two small ICT companies in Vietnam to determine how knowledge transfer was conducted with and without the use of ICT. A knowledge transfer framework for small businesses was used as a lens to analyse the results. The findings showed differences in knowledge transfer approaches in both cases. It was observed that employees whose jobs required less flexibility needed more explicit knowledge, but if their working procedures were more flexible they were more likely to need tacit knowledge. Tacit knowledge was mainly transferred by non-ICT methods, with explicit knowledge being transferred via a combination of methods. The cases differed in regard to the existence of knowledge transfer guidelines – as well as the willingness and ability of employees to share knowledge with others in the business. Both case businesses lacked appropriate measures to determine the level of success of knowledge transfer activities.  相似文献
