Evaluation of a REDCap-based Workflow for Supporting Federal Guidance for Electronic Informed Consent.

Adoption of electronic informed consent (eConsent) for research remains low despite evidence of improved patient comprehension, usability, and workflow processes compared to paper. At our institution, we implemented an eConsent workflow using REDCap, a widely used electronic data capture system. The goal of this study was to evaluate the extent to which the REDCap eConsent solution adhered to federal guidance for eConsent.

Relation between temporal perception and inhibitory control in the Go/No-Go task.

This research was designed to replicate and extend findings concerning bidirectional interference between concurrent timing and inhibition tasks reported previously. Subjects performed serial temporal production and Go/No-Go (GNG) tasks under single-task and dual-task conditions in two experiments. The degree of inhibitory control required in the GNG tasks was manipulated by varying the proportion of go and no-go stimuli (experiment 1) and by instructing subjects to devote different amounts of attention to the dual tasks (experiment 2).

Executive attentional resources in timing: Effects of inhibitory control and cognitive aging.

This research is based on an executive resource theory of timing, which postulates that time perception relies on specialized attentional resources that support executive cognitive functions. In 4 experiments, older and younger participants performed a timing task and an executive task emphasizing inhibitory control under both single-task and dual-task conditions. The timing task in each experiment was serial temporal production.

Time perception and temporal order memory.

The purpose of this research was to investigate the relation between the attentional resources underlying time perception and temporal order memory. Subjects made judgments about temporal attributes associated with a series of wordlists. Each word was displayed for 1.

Implementing a Clinical Research Management System: One Institution's Successful Approach Following Previous Failures.

Clinical research management systems (CRMSs) can facilitate research billing compliance and clinician awareness of study activities when integrated with practice management and electronic health record systems. However, adoption of CRMSs remains low, and optimal approaches to implementation are unknown. This case report describes one institution's successful approach to organization, technology, and workflow for CRMS implementation following previous failures.

Involvement of shared resources in time judgment and sequence reasoning tasks.

Previous research suggests that time perception is supported by the same attentional resources involved in sequence processing. The present experiment was designed to clarify this connection by examining the relation between timing and reasoning tasks that involved either sequencing or non-sequencing judgments. For the timing task, subjects produced a series of 5-s intervals.

Timing and executive resources: dual-task interference patterns between temporal production and shifting, updating, and inhibition tasks.

Three dual-task experiments were designed to assess the contribution of executive cognitive functions to the perception of time. Each experiment combined a serial temporal production timing task with an executive task emphasizing either shifting, updating, or inhibition. The experiments uncovered evidence of bidirectional interference between the concurrent tasks, such that the executive tasks interfered with timing performance and the timing task interfered with executive performance.

Using the Mixed Rasch Model to analyze data from the beliefs and attitudes about memory survey.

In this study, we used the Mixed Rasch Model (MRM) to analyze data from the Beliefs and Attitudes About Memory Survey (BAMS; Brown, Garry, Silver, and Loftus, 1997). We used the original 5-point BAMS data to investigate the functioning of the "Neutral" category via threshold analysis under a 2-class MRM solution. The "Neutral" category was identified as not eliciting the model expected responses and observations in the "Neutral" category were subsequently treated as missing data.

Hydration status, knowledge, and behavior in youths at summer sports camps.

Purpose: To assess the hydration status and level of hydration knowledge of youths at summer sports camps.

Methods: Sixty-seven active youths, 57 males (mean +/- SD, 12 +/- 2 y, 136 +/- 16 cm, 50.6 +/- 21.

The attenuation effect in timing: counteracting dual-task interference with time-judgment skill training.

A basic finding in the time-perception literature is an interference effect in dual-task conditions involving concurrent timing and distractor tasks. Dual-task conditions typically cause time judgments to become less accurate than single-task conditions in which subjects judge time alone. Previous research (Brown, 1998 Psychological Research 61 71-81; Brown and Bennett, 2002 Psychological Research 66 80-89) has shown that practice on the distractor task reduces interference, a phenomenon called the attenuation effect.

Processing resources in timing and sequencing tasks.

Subjects performed timing and sequencing tasks under separate (single-task) and concurrent (dual-task) conditions in two experiments. The timing task required the subjects to generate a series of 5-sec temporal productions. The sequencing task in Experiment 1 involved verifying reasoning statements that described the ordering of a pair of letters.

Mania in a case of hyperparathyroidism.

Psychiatric manifestations of primary hyperparathyroidism are mediated by hypercalcemia. To date, most evidence indicates that hypercalcemia and increased cerebrospinal-fluid calcium levels produce depression symptoms. Presented here is a case report of a 52-year-old woman in a manic state.

Timing and executive function: bidirectional interference between concurrent temporal production and randomization tasks.

A review of interference effects in concurrent temporal/nontemporal dual-task studies suggests that prospective timing may be related to executive cognitive functions. Executive processes play a supervisory role in behavior by controlling attention, coordinating information, and scheduling actions. In the present research, a timing task was paired with an established executive task in a dual-task paradigm.

A study of technical signs in science: implications for lexical database development.

Both classroom instruction and lexical database development stand to benefit from applied research on sign language, which takes into consideration American Sign Language rules, pedagogical issues, and teacher characteristics. In this study of technical science signs, teachers' experience with signing and, especially, knowledge of content, were found to be essential for the identification of signs appropriate for instruction. The results of this study also indicate a need for a systematic approach to examine both sign selection and its impact on learning by deaf students.

Catecholamines in a macrophage cell line.

This study provides the first evidence for catecholamine synthesis and release in the RAW264.7 cell line, an important macrophage model. Although catecholamines were low in unstimulated cells, activation with lipopolysaccharide (LPS) induced tyrosine hydroxylase (TH) mRNA and increased extracellular norepinephrine and intracellular dopamine within 48 h.

Glenohumeral joint total rotation range of motion in elite tennis players and baseball pitchers.

Unlabelled: The amount of glenohumeral joint internal and external rotation used during overhead sport activities has been measured experimentally by sports scientists. Clinical measurement of glenohumeral joint internal and external rotation using goniometry is an integral part of a shoulder evaluation after injury or surgery or during preseason or preventative musculoskeletal screenings.

Purpose: This study measured glenohumeral joint internal and external rotation in two groups of unilaterally dominant upper extremity athletes to compare the total arc of rotational range of motion between the dominant and nondominant extremities.

Intrarater and interrater reliability of a manual technique to assess anterior humeral head translation of the glenohumeral joint.

The purpose of this study was to determine the intrarater and interrater reliability of a manual anterior humeral head translation test. Fifteen subjects were positioned lying in a supine position with their identity shielded from examiners. A standard manual anterior humeral head translation test was performed and repeated with the glenohumeral joint in 90 degrees of elevation in the scapular plane, with use of the grading method proposed by Altchek and Dines in 1993.

Attentional processes in time perception: effects of mental workload and event structure.

The role of attention in timing was evaluated in 2 experiments. In Experiment 1, participants reproduced the durations of melodies with either a coherent or an incoherent structure. Participants were tested under control (timing only) and detection (timing plus target detection) workload conditions.
