A Theoretically Informed mHealth Intervention to Improve Medication Adherence by Adults with Chronic Conditions: Technology Acceptance Model-Based Smartphone Medication Reminder App Training Session

Indiana University-Purdue University Indianapolis (IUPUI)Medication nonadherence among middle-aged to older adults with chronic conditions often stems from forgetting to take or fill medications as prescribed. A pilot study indicated the feasibility of technology acceptance model (TAM)-based smartphone medication reminder app (SMRA) training as a way to promote their app use and medication adherence. This dissertation assesses the viability and effect size of the modified TAM-based SMRA training in promoting app use and medication adherence, as well as its delivery design in preparation for a larger efficacy study. A two-group pretest-posttest design was employed. Twenty-nine adults aged over 40 years and taking medications for chronic condition management were recruited from Midwestern university and community sites. The training group (n = 15) received the modified TAM-based SMRA training; whereas the non-training group (n = 14) self-navigated app features. The training group reported significantly higher levels of perceived usefulness, perceived ease of use, positive subjective norm, and intention to use the app. In addition, the training group reported a higher proportion of active app use than the non-training group. Modified TAM-based SMRA training was not viable in increasing the levels of medication adherence variables. Effect sizes suggested at least 52 participants as a sample size for a larger efficacy study. Participants suggested that training could be improved by scheduling separate group training for iPhone and Android phone users, providing a live online training option, providing small group training with peer helper, tailoring training length to participant preference, and working with family members and healthcare providers as co-trainees and co-trainers

The health-related uses and gratifications of YouTube: Motive, cognitive involvement, online activity, and sense of empowerment

Indiana University-Purdue University Indianapolis (IUPUI)The purpose of this study was to examine the relationships among motives for health-related YouTube use, cognitive involvement with health information on YouTube, post-exposure online activity, and sense of empowerment regarding health and health care. As a result of the analysis of data from 263 participants, social utility, convenient information-seeking, habit-passing time, and exciting entertainment motives were identified as four motives for health-related YouTube use. Social utility and convenient information-seeking motives were positively related to cognitive involvement and cognitive involvement was positively related to perceived control. Social utility motive was negatively related to perceived competence, whereas convenient information-seeking motive was positively related to perceived competence. Habit-passing time motive was negatively related to goal internalization, whereas convenient information-seeking and exciting entertainment motives were positively related to goal internalization. The findings from this study imply that YouTube could be a useful health communication media for health professionals and organizations to use for empowering users in coping with health-related concerns

Antecedents of Job Satisfaction among Intimate Partner Violence Shelter Staff: Coworker Relational Maintenance Strategies, Communication Satisfaction, Burnout and Organizational Commitment

poster abstractThis study sought to extend prior research by examining the prevalence of relational maintenance strategies between coworkers and the impact of such strategies on work related attitude of job satisfaction, organizational commitment, communication satisfaction, and burnout with work. The targeted samples for this research were the employees of a battered women’s shelter located in Indianapolis, Indiana. A questionnaire was constructed that included established scales in order to measure independent and dependent variables. The questionnaires were distributed among the employees and 47.82% agreed to participate in this study. Regression analyses were conducted to analyze the collected data. The findings indicated the importance of assurances and conflict management among staffs in mitigating their job stresses and increasing their personal accomplishment, communication satisfaction, organizational commitment and job satisfaction

Modeling and Control of a Soft Robotic Fish with Integrated Soft Sensing

Soft robotics can be used not only as a means of achieving novel, more lifelike forms of locomotion, but also as a tool to understand complex biomechanics through the use of robotic model animals. Herein, the control of the undulation mechanics of an entirely soft robotic subcarangiform fish is presented, using antagonistic fast‐PneuNet actuators and hyperelastic eutectic gallium–indium (eGaIn) embedded in silicone channels for strain sensing. To design a controller, a simple, data‐driven lumped parameter approach is developed, which allows accurate but lightweight simulation, tuned using experimental data and a genetic algorithm. The model accurately predicts the robot's behavior over a range of driving frequencies and a range of pressure amplitudes, including the effect of antagonistic co‐contraction of the soft actuators. An amplitude controller is prototyped using the model and deployed to the robot to reach the setpoint of a tail‐beat amplitude using fully soft and real‐time strain sensing

Measurement of the branching fractions of Bˉ→D(∗)K−K(S)(∗)0\bar{B}\to D^{(*)} K^- K^{(*)0}_{(S)} and Bˉ→D(∗)Ds−\bar{B}\to D^{(*)}D_s^{-} decays at Belle II

International audienceWe present measurements of the branching fractions of eight $\overline B{}^0\to D^{(*)+} K^- K^{(*)0}_{(S)}$, $B^{-}\to D^{(*)0} K^- K^{(*)0}_{(S)}$ decay channels. The results are based on data from SuperKEKB electron-positron collisions at the $\Upsilon(4S)$ resonance collected with the Belle II detector, corresponding to an integrated luminosity of $362~\text{fb}^{-1}$. The event yields are extracted from fits to the distributions of the difference between expected and observed $B$ meson energy, and are efficiency-corrected as a function of $m(K^-K^{(*)0}_{(S)})$ and $m(D^{(*)}K^{(*)0}_{(S)})$ in order to avoid dependence on the decay model. These results include the first observation of $\overline B{}^0\to D^+K^-K_S^0$, $B^-\to D^{*0}K^-K_S^0$, and $\overline B{}^0\to D^{*+}K^-K_S^0$ decays and a significant improvement in the precision of the other channels compared to previous measurements. The helicity-angle distributions and the invariant mass distributions of the $K^- K^{(*)0}_{(S)}$ systems are compatible with quasi-two-body decays via a resonant transition with spin-parity $J^P=1^-$ for the $K^-K_S^0$ systems and $J^P= 1^+$ for the $K^-K^{*0}$ systems. We also present measurements of the branching fractions of four $\overline B{}^0\to D^{(*)+} D_s^-$, $B^{-}\to D^{(*)0} D_s^-$ decay channels with a precision compatible to the current world averages

Test of light-lepton universality in τ\tau decays with the Belle II experiment

We present a measurement of the ratio $R_\mu = \mathcal{B}(\tau^-\to \mu^-\bar\nu_\mu\nu_\tau) / \mathcal{B}(\tau^-\to e^-\bar\nu_e\nu_\tau)$ of branching fractions $\mathcal{B}$ of the $\tau$ lepton decaying to muons or electrons using data collected with the Belle II detector at the SuperKEKB $e^+e^-$ collider. The sample has an integrated luminosity of 362 fb$^{-1}$ at a centre-of-mass energy of 10.58 GeV. Using an optimised event selection, a binned maximum likelihood fit is performed using the momentum spectra of the electron and muon candidates. The result, $R_\mu = 0.9675 \pm 0.0007 \pm 0.0036$, where the first uncertainty is statistical and the second is systematic, is the most precise to date. It provides a stringent test of the light-lepton universality, translating to a ratio of the couplings of the muon and electron to the $W$ boson in $\tau$ decays of $0.9974 \pm 0.0019$, in agreement with the standard model expectation of unity

Measurement of the Ωc0\Omega_c^0 lifetime at Belle II

We report on a measurement of the $\Omega_c^0$ lifetime using $\Omega_c^0 \to \Omega^-\pi^+$ decays reconstructed in $e^+e^-\to c\bar{c}$ data collected by the Belle II experiment and corresponding to $207~{\rm fb^{-1}}$ of integrated luminosity. The result, $\rm\tau(\Omega_c^0)=243\pm48( stat)\pm11(syst)~fs$, agrees with recent measurements indicating that the $\Omega_c^0$ is not the shortest-lived weakly decaying charmed baryon
