Following the 20-min TTE recovery, lactate was 24 % lower in BA compared to PLA (4.35 vs. 5.76 mmol/L, respectively). No differences existed for variables during intermittent weeks. 28 days of BA supplementation increased cycling performance via an enhanced time to exhaustion and total work completed with associated lactate clearance during passive rest in female MA.

Performance of Nonparametric Person-Fit Statistics with Unfolding versus Dominance Response Models

Nonparametric person fit statistics do not require fitting a parametric test theory model and have performed well compared to other person-fit statistics. However, detection of aberrant responding has primarily focused on dominance response data, thus the effectiveness of person-fit statistics in detecting different aberrant behaviors in ideal point data is unclear. This study compares the performance of nonparametric person-fit statistics in unfolding and dominance model contexts. Results for dominance data indicate that increases in detection rates depend, among other factors, on type of aberrant responding and person-fit statistic used. The detection of aberrant responses in ideal point data was ineffective using four nonparametric person-fit statistics, with slightly higher type I error and power less than 0.25. Additional research is needed to identify or develop nonparametric or parametric...
EDUCATIONAL LEADERSHIP & MANAGEMENT | RESEARCH ARTICLE On the frontline of CCSS implementation: A national study of factors influencing teachers' perceptions of teaching conditions and job satisfaction

As an increasingly integral part of the school accountability movement under No Child Left Behind and Race to the Top, respon- sibility for implementing CCSS rests largely with school leadership. One important factor in the success or failure of these efforts is the perceptions and experiences of the teachers who will ultimately employ CCSS in the classroom. This survey study examined teachers' views of CCSS implementation, teaching conditions, collabora- tion, and job satisfaction. Factor analysis revealed that the openness and activeness of school leadership had a significant effect on teachers' perceptions of implemen- tation, suggesting that attention to these aspects of leadership is an important consideration during transition to CCSS.

Gender differences on anxiety and stress have been documented when items are written using positive versus negative wording formats. One limitation of item wording research is whether differences are due to wording or differences in constructs when positive and negative items are not matched on content. In this study, ten items from the Zung (1971) Anxiety Scale were selected, and ten items were created to be the reverse wording of the original items. The purpose was to investigate the functioning of reverse-worded items for males and females of different age groups. A volunteer sample of 2,540 adults was collected. Data were disaggregated by gender and age. Differential bundle functioning analyses were conducted using POLY-SIBTEST with ten positively worded items used as the matching subtest to compare responses on ten negatively worded items (5 point scale). When women were matched with men, there was no significant difference on negatively worded items (b uni = 0.070, p = .702). Neither were there gender differences across age categories. However, when adults were compared by age, older adults were significantly less likely than young adults to agree with negatively worded anxiety items. To better understand the differences, women in three age groups were compared and results indicated significant differences between all comparisons (b uni = 0.554, p = .003 for 18-39 versus 40-59 years; b uni = 0.686, p = .005 for 40-59 versus 60 years and older; b uni = 1.030, p < .001 for 18-39 versus 60 years and older). The same age-related trend was observed for males, with the youngest males significantly more likely to agree with negative items than the oldest males (b uni = 1.026, p = .003). Results indicate that previous gender studies on anxiety scales may be confounded by age.
POSTER: Multidimensional Item Response Theory Analysis of the 10-item Perceived Stress Scale
The Perceived Stress Scale (PSS, Cohen & Williamson, 1988) is a widely used measure of self-r... more The Perceived Stress Scale (PSS, Cohen & Williamson, 1988) is a widely used measure of self-report of perceived stress. Principal components factor analysis often results in a two-factor solution composed of either positively worded (PW) or negatively worded (NW) items (see Lee [2012]). Cohen and Williamson stated that the distinction between factors was irrelevant for purposes of measuring perceived stress. For this reason, data tends to be viewed from a unidimensional standpoint. The purpose of this study was to analyze responses to the PSS using unidimensional and multidimensional graded response model IRT and to compare the estimated item parameters and trait scores. Responses to the 10-item PSS were gathered from 1,388 participants using a voluntary sample. The multidimensional model had a significantly better fit to the data over the unidimensional model. On average, item parameters were estimated with smaller standard errors from the unidimensional model. Scores from the unidimensional and multidimensional model were not significantly different for the entire sample, but were within subgroups. Males had a significantly different estimated score on the two dimensions from the multidimensional model; the score on the negative dimension was significantly different from the unidimensional score, but the score on the positive dimension was not. Females did not have significantly different scores on the two dimensions from the multidimensional, but each was significantly different from the unidimensional score. Within different age categories, there was no significant difference in the two trait scores from the multidimensional model, but there were significant differences in unidimensional scores those on one of the two dimensions for certain groups. Though the unidimensional model is most often applied to psychometric scales with PW and NW items, a multidimensional model may provide a more valid measure of a construct when responses are influenced by the wording direction.

The focus of this descriptive study was on identifying the preferences faculty who teach online have regarding how they want to learn about new technology, how to complete tasks in the online environment, and strategies they can use to enhance instruction. Additionally, the study sought to gauge faculty members' interest in working with other faculty to investigate online teaching issues. Results from a survey instrument administered to faculty who teach online at an institution in the mid-south indicate that faculty members prefer one-on-one meetings with instructional design experts, online resources, and informal interaction with colleagues. The authors recommend including faculty members' input in the design of professional development initiatives.
Do Fetal Development Markers Influence Attitudes toward Abortion Legality?

We found that people’s support for legal abortion decreases when survey items mention fetal developmental markers compared with items that do not. However, the majority of participants supported access to legal abortion in health-related circumstances or pregnancies as a result of rape at the detection of a fetal heartbeat. Using terms that personify the fetus may evoke responses from participants that limit their endorsement of abortion. Thus, including this terminology in the public and political discourse seems to influence abortion attitudes. This might have implications related to electoral outcomes which eventually determine whether pregnant people are guaranteed access to abortion.
