How honest are the signals? A protocol for validating wearable sensors.

There is growing interest among organizational researchers in tapping into alternative sources of data beyond self-reports to provide a new avenue for measuring behavioral constructs. Use of alternative data sources such as wearable sensors is necessary for developing theory and enhancing organizational practice. Although wearable sensors are now commercially available, the veracity of the data they capture is largely unknown and mostly based on manufacturers' claims. The goal of this research is to test the validity and reliability of data captured by one such wearable badge (by Humanyze) in the context of structured meetings where all individuals wear a badge for the duration of the encounter. We developed a series of studies, each targeting a specific sensor of this badge that is relevant for structured meetings, and we make specific recommendations for badge data usage based on our validation results. We have incorporated the insights from our studies on a website that researchers can use to conduct validation tests for their badges, upload their data, and assess the validity of the data. We discuss this website in the corresponding studies.

Educating leaders in nursing: faculty perspectives.

Recent changes in health care legislation have presented an unprecedented opportunity for nurses to engage as full partners in transforming health care (Institute of Medicine, 2010). According to diverse opinion leaders from insurance, corporate, health services, government, and higher education, nurses should have more influence than they do now on health policy, planning, and management (Robert Wood Johnson Foundation, 2010). More than ever before, nursing needs leaders, and nursing faculty are in a pivotal position to educate leaders in nursing. This article describes the findings of a descriptive study that surveyed nursing faculty teaching in all degree levels to ascertain how they prepare students to be leaders in nursing. Data were analyzed using qualitative methods. Findings demonstrate that faculty engage in self-development as leaders, promote student role development as leaders, and use multiple teaching-learning strategies to educate students to be leaders in nursing.

Association of Self-Administered Nitrous Oxide for Labor Analgesia With Maternal and Neonatal Process and Outcome Measures.

OBJECTIVE: To describe patterns of use of self-administered nitrous oxide (N2O) during labor and to determine if maternal and neonatal process and outcome measures differ for women who use N2O compared to women who do not use N2O. DESIGN: Retrospective, full-census, observational cohort. SETTING: An upper midwestern U.S., urban, 75-bed quaternary perinatal center with more than 5,000 annual births. PARTICIPANTS: The participants included two groups of women: 400 who used N2O during labor and a comparison group of 6,733 who met N2O eligibility but did not use N2O. METHODS: We used descriptive statistics to examine patterns of use of N2O during labor between January 2015 and March 2017. We examined associations of N2O with process (length of first and second stages of labor, time from hospital admission to birth, time from birth to hospital discharge, and total length of stay) and outcome measures (shoulder dystocia, instrumentation, vaginal lacerations, Apgar scores at 5 minutes, nursery disposition) using multivariate linear, logistic, and ordinal regression models. RESULTS: Three percent (12/400) of women who used N2O discontinued because of side effects. Among participants with vaginal births who used N2O, 17.6% (62/352) used N2O as the only form of pain medication during labor. We found no significant differences in maternal and neonatal outcome measures between the two groups. Among the process measures examined, we found a mean 2-hour-longer time from admission to birth and total length of stay in the N2O group (p < .05) compared to the non-N2O group. CONCLUSION: Most participants who used N2O (290/352, 82.3%) transitioned to other pain modalities during labor. Maternal and neonatal process and outcome measures were comparable relative to other pain management modalities, with the exception of longer time durations for two measures.

Teeth are for chewing: a critical review of the conceptualisation and ethics of a controversial intraoral weight-loss device.

We are a diverse collective of researchers who are committed to improving the health and wellbeing of marginalised individuals. This article is a response to, and critique of, the DentalSlim Diet Control research. This device revises a controversial 1970s weight-loss technology connected to poor health outcomes, which is indicative of a culture that consistently promotes harm to fat and other marginalised communities.We address the historical context in which unruly bodies, particularly fat, and Indigenous bodies have been the site of unethical investigation conducted under the auspices of medical research. Existence outside the normative white, male, cis physical ideal demands regulation, and disciplinary measures. We demonstrate how Brunton et al.'s research is underpinned by anti-fat attitudes and assumptions which impose this punitive physical intervention onto healthy people in a way that should not be acceptable in medical research.Further, we address a range of harms, giving attention to Maori and to individuals with eating disorders, along with issues of research integrity. We argue that no ethics committee should have approved this research, no academic journal should have published it, and no member of the dental and medical community should promote or prescribe this device.

A Data Snapshot Approach for Making Real-Time Predictions in Basketball.

This article proposes a novel approach, called data snapshots, to generate real-time probabilities of winning for National Basketball Association (NBA) teams while games are being played. The approach takes a snapshot from a live game, identifies historical games that have the same snapshot, and uses the outcomes of these games to calculate the winning probabilities of the teams in this game as the game is underway. Using data obtained from 20 seasons worth of NBA games, we build three models and compare their accuracies to a baseline accuracy. In Model 1, each snapshot includes the point difference between the home and away teams at a given second of the game. In Model 2, each snapshot includes the net team strength in addition to the point difference at a given second. In Model 3, each snapshot includes the rate of score change in addition to the point difference at a given second. The results show that all models perform better than the baseline accuracy, with Model 1 being the best model.

PACU fast-tracking: an alternative to "bypassing" the PACU for facilitating the recovery process after ambulatory surgery.

This retrospective evaluation assessed the impact of discharging outpatients home directly from the PACU as an alternative to "PACU bypassing." A total of 1,380 outpatients who had undergone minor ambulatory procedures were evaluated. Nine hundred fifty-two outpatients were admitted to a designated PACU fast-tracking area to facilitate an earlier discharge. Of the outpatients admitted to the PACU fast-track area, 88% were discharged home within 60 minutes (mean time [+/- SD] of 58 +/- 8 minutes]. The remaining 12% were discharged home from the PACU in an average of 88 (+/- 12) minutes. The recovery times for the 428 outpatients who were initially considered for the PACU fact-tracking program but were admitted to the regular PACU and recovered according to the conventional (two-step) pathway were 38 +/- 25 minutes in the PACU, followed by 61 +/- 32 minutes in the day surgery step-down unit. We conclude that this pilot program demonstrates the feasibility of discharging patients home from the PACU. Only 12% of the outpatients who were admitted to the PACU fast-track area failed to be discharged within 60 minutes. The overall times to discharge from the PACU fast-track area compared favorably to discharge times for outpatients bypassing the PACU. This program provides nurses with an alternative recovery pathway for fast-tracking patients after ambulatory surgery.
