THE MEDIATING EFFECT OF INFORMATION AND COMMUNICATION TECHNOLOGY LEARNING ON THE RELATIONSHIP BETWEEN SOCIAL MEDIA USAGE AND INFORMATION-SEEKING BEHAVIOR OF STUDENTS

This study aimed to determine the mediating effect of information and communication technology learning on the relationship between social media usage and students' behavior from the Bachelor of Science and Technology program at the University of Mindanao. A stratified random sampling method was used, with 300 students serving as respondents. The results of a non-experimental quantitative mediation analysis using a validated questionnaire, mean, regression techniques, and Pearson r revealed a significant relationship between social media usage, behavior, and information and communication technology learning. Results of the study showed that students' level of social media usage was moderate. The study also revealed that students' level of information-seeking behavior was moderate. Further, there was a partial mediation on the effect of information and communication technology learning on the relationship between social media usage and information-seeking behavior. As a result, one of the reasons why social media usage can influence information-seeking behavior is information and communication technology learning. Nevertheless, it cannot wholly account for the relationship between the two variables.  Article visualizations

Factors that Impede the Formation of Self-Directed work teams in Mexican Organizations

The most efficient work teams are self-directed work teams (SDWTs). In the United States, seventy-five percent of medium and large companies use SDWTs. The United States has a higher economic performance than Mexico. In Mexico, SDWTs have not been successful. The objective of this document is to identify the factors that impede the formation of SDWTs in Mexican organizations. Qualitative research was carried out with a cross-correlational design. The sample consisted of 32 employees from Mexican companies. The chi-square statistical test was used to evaluate the relationship between the variables. The dependent variable was the formation of the SDWTs, and the independent variables were the multidisciplinary knowledge of the individuals, the empowerment of team members and multidisciplinary work teams (work teams with members from a variety of disciplines). The results showed that only the multidisciplinary knowledge of the individuals and multidisciplinary work teams are dependent variables in the formation of SDWTs. Therefore, the conclusion is that empowerment has been exercised in Mexican companies and it is not an impediment to the formation of SDWTs

The PROVENT-C19 registry: A study protocol for international multicenter SIAARTI registry on the use of prone positioning in mechanically ventilated patients with COVID-19 ARDS

Background The worldwide use of prone position (PP) for invasively ventilated patients with COVID-19 is progressively increasing from the first pandemic wave in everyday clinical practice. Among the suggested treatments for the management of ARDS patients, PP was recommended in the Surviving Sepsis Campaign COVID-19 guidelines as an adjuvant therapy for improving ventilation. In patients with severe classical ARDS, some authors reported that early application of prolonged PP sessions significantly decreases 28-day and 90-day mortality. Methods and analysis Since January 2021, the COVID19 Veneto ICU Network research group has developed and implemented nationally and internationally the "PROVENT-C19 Registry", endorsed by the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care. . .'(SIAARTI). The PROVENT-C19 Registry wishes to describe 1. The real clinical practice on the use of PP in COVID-19 patients during the pandemic at a National and International level; and 2. Potential baseline and clinical characteristics that identify subpopulations of invasively ventilated patients with COVID-19 that may improve daily from PP therapy. This web-based registry will provide relevant information on how the database research tools may improve our daily clinical practice. Conclusions This multicenter, prospective registry is the first to identify and characterize the role of PP on clinical outcome in COVID-19 patients. In recent years, data emerging from large registries have been increasingly used to provide real-world evidence on the effectiveness, quality, and safety of a clinical intervention. Indeed observation-based registries could be effective tools aimed at identifying specific clusters of patients within a large study population with widely heterogeneous clinical characteristics.

Salivary immunoreactive insulin: a new entry in clinical chemistry?

Abstract The distribution of salivary immunoreactive insulin (S-IRI) and its relation to plasma insulin (P-IRI) and other clinical and metabolic variables were investigated in 93 nondiabetic subjects (60 males, 33 females, ages 11-70 y). S-IRI was measured by RIA, with monoiodinated insulin as labeled antigen and with standards consisting of serial dilutions in saliva of known amounts of native insulin. The sensitivity of the method was 12.1 pmol/L. The intra- and between-assay CVs were near 10%, and analytical recovery exceeded 93% for various insulin concentrations added to saliva. S-IRI, measured after overnight fast, showed a nonguassian distribution in males (skewness 1.18, kurtosis 1.41) and females (skewness 1.71, kurtosis 1.18); mean and median values were higher in males (14.3 and 12.1 nmol/min) than in females (12.1 and 7.15 nmol/min), but not significantly so. S-IRI was significantly correlated with P-IRI both in males (r = 0.75, P less than 0.0001) and females (r = 0.72, P less than 0.0001). These results, particularly the correlation between S-IRI and P-IRI, indicate the possibility of using S-IRI measurement in clinical practice.</jats:p

Determination of AlGaN/GaN HEMT Reliability Using Optical Pumping as a Characterization Method

ABSTRACTBy pumping AlGaN/GaN HEMTs with below band-gap light we observe changes in drain current that correspond to the trapping and detrapping of carriers within the band-gap. These changes in drain current are indicators of trap density, since the energy from a specific wavelength of light pumps traps whose activation energies are less than or equal to that of the light source.AlGaN/GaN HEMTs on SiC with dual submicron gates with widths of 125nm, 140nm, or 170nm, are DC-stressed under three different conditions along a load line: VGS=0, VDS=5 (on-state), VGS=-2, VDS=9.2 and, VGS=-6, VDS=25 (off-state). The stress tests are interrupted at 20% degradation and the optically pumped comparisons to the baseline are measured.This paper describes the optical pumping technique and results from experiments of AlGaN/GaN HEMTs under the three DC stress biases along a load line.</jats:p
