“Ethics When You Least Expect It”: A Modular Approach to Short Course Data Ethics Instruction

Science and Engineering Ethics - Data science skills are rapidly becoming a necessity in modern science. In response to this need, institutions and organizations around the world are developing...     

Attentional demands associated with obstacle crossing while carrying a load

The extent to which different locomotor tasks require cognitive control is not well characterized. In this article, the authors consider the potential increase in attentional demands associated with carrying an anterior load while clearing an obstacle. Nine healthy male volunteers participated in 80 walking trials, 20 in each of 4 conditions: 1 no load condition (NL) and 3 carrying conditions (2KG, 5KG, and 10KG). Of the 20 trials in each condition, 12 included a probe reaction time (PRT) test during lead limb obstacle crossing, which was used to measure cognitive load. A load-dependent increase in PRT was observed, with PRT in the 2KG condition being significantly greater than in the NL condition, and PRT in the 5KG and 10KG conditions being significantly greater than in the 2KG condition. These results suggested that cognitive load was increased when: (a) the obstacle was occluded from vision by the load, and (b) the magnitude of load was increased.     

A longitudinal evaluation of prevalent negative beliefs about residential placement for troubled adolescents

To investigate the validity of five prevalent negative beliefs about residential placement, we followed adolescents from a residential program and a comparison group at 3-month intervals for 4 to 8 years. This residential program in the Midwest uses the Teaching-Family Model in which six to eight adolescents live in a family-style environment. The interviews included five scales reflecting youths' views about important aspects of their lives in placement: (1) Delivery of Helpful Treatment, (2) Satisfaction with Supervising Adults, (3) Isolation from Family, (4) Isolation from Friends, and (5) Sense of Personal Control. Hierarchical linear modeling allowed us to estimate group differences while controlling for developmental trends, demographic factors, and prior differences between groups. The two groups were equivalent on all scales before the study. During the following placement, however, the treatment group's ratings were significantly more positive than the comparison group on four of the five scales and approached significance on the fifth. These findings suggest that negative beliefs about life in residential placement for adolescents may not apply to all programs.The authors acknowledge Gaylon Oswalt, Beth Chmelka, and Brian Noss for their assistance on this study and Richard Dangel, Thomas Dows, Robert Hawkins, Kathleen Lenerz, Kevin Moore, James Whittaker, and Montrose Wolf for helpful comments on this paper.     

Conflict frequency with mothers and fathers from middle childhood to late adolescence: within- and between-families comparisons

The authors examined siblings' dyadic and differential conflict frequency with mothers and fathers from 7 to 19 years of age. Participants were first- and second-borns from 201 families who reported their conflict with each parent in 4 home interviews spaced over 5 years. Multilevel models examining trajectories of conflict frequency across age and year of study revealed that (a) consistent with a spillover hypothesis, elevation in parent-offspring conflict frequency was timed to firstborns' transition to adolescence for both siblings; and (b) consistent with a learning-from-experience hypothesis, there was no increase in conflict frequency at second-borns' transition to adolescence. These findings highlight the importance of studying the development of parent-offspring conflict within the larger family system.     

The tie effect in simple arithmetic: An access-based account

Simple arithmetic problems with repeated operands (i.e., ties such as 4 + 4, 6 x 6, 10 - 5, or 49 / 7) are solved more quickly and accurately than similar nontie problems (e.g., 4 + 5, 6 x 7, 10 - 6, or 48 / 6). Further, as compared with nonties, ties show small or nonexistent problem-size effects (whereby problems with smaller operands such as 2 + 3 are solved more quickly and accurately than problems with larger operands such as 8 + 9). Blankenberger (2001) proposed that the tie advantage occurred because repetition of the same physical stimulus resulted in faster encoding of tie than of nontie problems. Alternatively, ties may be easier to solve than nonties because of differences in accessibility in memory or differences in the solution processes. Adults solved addition and multiplication (Experiment 1) or subtraction and division (Experiment 2) problems in four two pure formats (e.g., 4 + 4, FOUR + FOUR) and two mixed formats (e.g., 4 + FOUR, and FOUR + 4). Tie advantages were reduced in mixed formats, as compared with pure formats, but the tie x problem-size interaction persisted across formats. These findings support the view that tie effects are strongly related to memory access and are influenced only moderately by encoding factors.     

The Process of Occupational Decision Making: Patterns during the Transition to Adulthood

In this paper, we consider how recent social changes in the United States may be affecting vocational decision making. While adolescents often maintain high educational and occupational aspirations, the transition from school is characterized by few institutional supports, the prolongation of education, and a multitude of options with respect to the combination of school, work, and family. In such a context, what themes characterize decision making about schooling and occupational careers? We draw on qualitative interviews collected as part of the Youth Development Study (n=1000), a longitudinal study of work through adolescence and early adulthood. Multiple themes were identified including unfulfilled expectations, the postponement of decisions, turning points that crystallized decisions, and resources and obstacles including, among others, family, work, school counseling, and teachers. These themes characterize contemporary occupational decision making and thus would be appropriate focal points for future research. They also suggest that social policies may need to be modified to facilitate the young people's quest for vocational identity and work.     

“Visiting Day” at Rikers Island

Wacquant (2002) calls for ethnography to meet the jailhouse on its own terms, noting the dearth of first-hand writing from the carceral facility. This article describes a creative representation of qualitative research made by the author and two creative collaborators that both meets Wacquant’s call and problematizes it; meets it, as we depict the functioning of the visitation process at Rikers Island based on our first-hand experience on both sides of the bars, and problematizes it, as we chose for our medium the zine, a creative form common to prison writing, yet not sufficiently academic by Wacquant’s standards. I offer a novel definition of the zine form grounded in the academic literature, describe the visitation process at Rikers and the making of the “Visiting Day” zine, and reflect on challenges to the binary of inside/outside the carceral facility, as well as the political stakes of this theoretical formulation.
