Adaptación al español de una escala de motivación emprendedora

This study follows the theoretical framework put forward by Robichaud on entrepreneurial motivation. The objective was to adapt the original French scale of 17 items into Spanish and to analyze its psychometric properties. The participants in the present study were 981 Spanish employees (46.5 % men and 53.5 % women). After carrying out exploratory factor analyses and ESEM (RMSEA = .06; CFI = .95 and TLI = .95), revealed a structure comprised of three factors: Family security (α =.82), Independence and autonomy (α =.83), and Intrinsic motivations (α =.77). These three factors displayed adequate reliability. We also found evidence of validity with regard to a series of external correlates and various scales that have to do with workaholism, irritation and burnout. The present scale may prove useful for adequately identifying entrepreneurial motivation.Este estudio sigue el marco teórico propuesto por Robichaud sobre motivación emprendedora.

Experimenter Effects on Pain Reporting in Women Vary across the Menstrual Cycle

Background. Separate lines of research have shown that menstrual cycling and contextual factors such as the gender of research personnel influence experimental pain reporting. Objectives. This study examines how brief, procedural interactions with female and male experimenters can affect experimentally reported pain (cold pressor task, CPT) across the menstrual cycle. Methods. Based on the menstrual calendars 94 naturally cycling women and 38 women using hormonal contraceptives (Mage=19.83,  SD=3.09) were assigned to low and high fertility groups. This assignment was based on estimates of their probability of conception given their current cycle day. Experimenters (12 males, 7 females) engaged in minimal procedural interactions with participants before the CPT was performed in solitude. Results. Naturally cycling women in the high fertility group showed significantly higher pain tolerance (81 sec, d=.79) following interactions with a male but not a female experimenter. Differences were not found for women in the low fertility or contraceptive groups. Discussion. The findings illustrate that menstrual functioning moderates the effect that experimenter gender has on pain reporting in women. Conclusion. These findings have implications for standardizing pain measurement protocols and understanding how basic biopsychosocial mechanisms (e.g., person-perception systems) can modulate pain experiences

D-cycloserine augmentation of exposure-based cognitive behavior therapy for anxiety, obsessive-compulsive, and posttraumatic stress disorders: a systematic review and meta-analysis of individual participant data

Importance: Whether and under which conditions D-cycloserine (DCS) augments the effects of exposure-based cognitive behavior therapy for anxiety, obsessive-compulsive, and posttraumatic stress disorders is unclear. Objective: To clarify whether DCS is superior to placebo in augmenting the effects of cognitive behavior therapy for anxiety, obsessive-compulsive, and posttraumatic stress disorders and to evaluate whether antidepressants interact with DCS and the effect of potential moderating variables. Data Sources: PubMed, EMBASE, and PsycINFO were searched from inception to February 10, 2016. Reference lists of previous reviews and meta-analyses and reports of randomized clinical trials were also checked. Study Selection: Studies were eligible for inclusion if they were (1) double-blind randomized clinical trials of DCS as an augmentation strategy for exposure-based cognitive behavior therapy and (2) conducted in humans diagnosed as having specific phobia, social anxiety disorder, panic disorder with or without agoraphobia, obsessive-compulsive disorder, or posttraumatic stress disorder. Data Extraction and Synthesis: Raw data were obtained from the authors and quality controlled. Data were ranked to ensure a consistent metric across studies (score range, 0-100). We used a 3-level multilevel model nesting repeated measures of outcomes within participants, who were nested within studies. Results: Individual participant data were obtained for 21 of 22 eligible trials, representing 1047 of 1073 eligible participants. When controlling for antidepressant use, participants receiving DCS showed greater improvement from pretreatment to posttreatment (mean difference, -3.62; 95% CI, -0.81 to -6.43; P = .01; d = -0.25) but not from pretreatment to midtreatment (mean difference, -1.66; 95% CI, -4.92 to 1.60; P = .32; d = -0.14) or from pretreatment to follow-up (mean difference, -2.98, 95% CI, -5.99 to 0.03; P = .05; d = -0.19). Additional analyses showed that participants assigned to DCS were associated with lower symptom severity than those assigned to placebo at posttreatment and at follow-up. Antidepressants did not moderate the effects of DCS. None of the prespecified patient-level or study-level moderators was associated with outcomes. Conclusions and Relevance: D-cycloserine is associated with a small augmentation effect on exposure-based therapy. This effect is not moderated by the concurrent use of antidepressants. Further research is needed to identify patient and/or therapy characteristics associated with DCS response.2018-05-0

Calibration of the MaGIXS experiment II: Flight Instrument Calibration

The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) is a sounding rocket experiment that observes the soft X-ray spectrum of the Sun from 6.0 - 24 Angstrom (0.5 - 2.0 keV), successfully launched on 30 July 2021. End-to-end alignment of the flight instrument and calibration experiments are carried out using the X-ray and Cryogenic Facility (XRCF) at NASA Marshall Space Flight Center. In this paper, we present the calibration experiments of MaGIXS, which include wavelength calibration, measurement of line spread function, and determination of effective area. Finally, we use the measured instrument response function to predict the expected count rates for MaGIXS flight observation looking at a typical solar active regionComment: 20 pages, 16 figures, Accepted for publication in the Astrophysical Journa

Proceedings of the 3rd Biennial Conference of the Society for Implementation Research Collaboration (SIRC) 2015: advancing efficient methodologies through community partnerships and team science

It is well documented that the majority of adults, children and families in need of evidence-based behavioral health interventionsi do not receive them [1, 2] and that few robust empirically supported methods for implementing evidence-based practices (EBPs) exist. The Society for Implementation Research Collaboration (SIRC) represents a burgeoning effort to advance the innovation and rigor of implementation research and is uniquely focused on bringing together researchers and stakeholders committed to evaluating the implementation of complex evidence-based behavioral health interventions. Through its diverse activities and membership, SIRC aims to foster the promise of implementation research to better serve the behavioral health needs of the population by identifying rigorous, relevant, and efficient strategies that successfully transfer scientific evidence to clinical knowledge for use in real world settings [3]. SIRC began as a National Institute of Mental Health (NIMH)-funded conference series in 2010 (previously titled the “Seattle Implementation Research Conference”; $150,000 USD for 3 conferences in 2011, 2013, and 2015) with the recognition that there were multiple researchers and stakeholdersi working in parallel on innovative implementation science projects in behavioral health, but that formal channels for communicating and collaborating with one another were relatively unavailable. There was a significant need for a forum within which implementation researchers and stakeholders could learn from one another, refine approaches to science and practice, and develop an implementation research agenda using common measures, methods, and research principles to improve both the frequency and quality with which behavioral health treatment implementation is evaluated. SIRC’s membership growth is a testament to this identified need with more than 1000 members from 2011 to the present.ii SIRC’s primary objectives are to: (1) foster communication and collaboration across diverse groups, including implementation researchers, intermediariesi, as well as community stakeholders (SIRC uses the term “EBP champions” for these groups) – and to do so across multiple career levels (e.g., students, early career faculty, established investigators); and (2) enhance and disseminate rigorous measures and methodologies for implementing EBPs and evaluating EBP implementation efforts. These objectives are well aligned with Glasgow and colleagues’ [4] five core tenets deemed critical for advancing implementation science: collaboration, efficiency and speed, rigor and relevance, improved capacity, and cumulative knowledge. SIRC advances these objectives and tenets through in-person conferences, which bring together multidisciplinary implementation researchers and those implementing evidence-based behavioral health interventions in the community to share their work and create professional connections and collaborations

The Acute Effect of Ascending-Pyramid, Descending-Pyramid, and Constant-Load Set Configurations on Repetition Performance, Training Volume, and Barbell Velocity During Bench Press Exercise

This study analyzed the effect of ascending pyramid (AP), constant load (CL), and descending pyramid (DP) training on repetition performance, training volume, barbell velocity, mechanical fatigue, and perceptual measurements during bench press exercise. Eighteen well-trained young males (18-40 years) performed AP, CL, and DP in a randomized order. Subjects were ranked according to relative strength ratio (Bench press 1-RM ÷ body mass) and the total sample of 18 males was divided into two groups: group 1 (G1), n = 9, RSR = 1.20-1.56; group 2 (G2), n = 9, RSR = 0.75-1.16. Volume (5 sets), relative intensity (65-85% 1-RM), set end point (25% velocity loss (VL)), and rest intervals (5 min) were matched between conditions. Relative intensity did not change during CL (75% 1-RM), while sets were performed from light-to-heavy during AP (65-70-75-80-85% 1-RM), and heavy-to-light during DP (85-80-75-70-65% 1-RM). Repetition performance, total volume load (TVL), mean and peak velocity, VL, and ratings of perceived exertion (set-RPE) were measured during each session while affect, discomfort, enjoyment, and session-RPE were measured after each session. Mean and peak velocity with 45% 1-RM were assessed before, 5-min after, and 10-min after each session. Data indicated that peak velocity and set-RPE were significantly lower during DP (p ≤ 0.05) while no differences were detected between AP and CL. Session x set interactions (p ≤ 0.05) were observed for repetition performance, mean velocity, peak velocity, VL, and set-RPE, but differences were likely influenced by fluctuating relative intensities during AP and DP. Data also revealed that lifters from G2 executed their repetitions with greater mean and peak velocities than G1 (p ≤ 0.05), suggesting that relative strength influences barbell velocity. In conclusion, AP, CL, and DP are viable options for training sessions, but the latter may negatively affect peak velocity
