Critical properties of the optical field localization in a three-dimensional percolating system: Theory and experiment

We systematically study the optical field localization in an active three-dimensional (3D) disordered percolating system with light nanoemitters incorporated in percolating clusters. An essential feature of such a hybrid medium is that the clusters are combined into a fractal radiation pattern, in which light is simultaneously emitted and scattered by the disordered structures. Theoretical considerations, based on systematic 3D simulations, reveal nontrivial dynamics in the form of propagation of localized field bunches in the percolating material. We obtain the length of the field localization and dynamical properties of such states as functions of the occupation probability of the disordered clusters. A transition between the dynamical states and narrow point-like fields pinned to the emitters is found. The theoretical analysis of the fractal field properties is followed by an experimental study of the light generation by nanoemitters incorporated in the percolating clusters. The experimental results corroborate theoretical predictions.Comment: 10 pages, 14 figures, to be published Chaos, Solitons & Fractal

Organizational Factors Contributing to Workplace Stress Among Office Professionals in Selected Hospitals in Laguna: Basis for Stress Management Program

This study determined the organizational factors contributing to workplace stress among office professionals in selected hospitals in Laguna that served as a basis for a stress management program. This quantitative research employed a descriptive correlational design using descriptive statistics in analyzing the data. Data were collected among 80 office professionals from four selected hospitals in Laguna, Philippines. Convenience sampling was utilized in choosing the respondents of the study. The study revealed that the respondents experienced or observed the following organizational factors: high in terms of leadership support, good for working conditions, fair for peer relationship, moderate for role ambiguity, while the workload is moderately heavy. It was also found out that the respondent’s physical and psychological stress is low. Moreover, correlation analysis revealed that role ambiguity, working condition, and leadership support is not significantly related to physical, psychological test, and the overall workplace stress and that there was no significant difference in the employees’ demographic profile considering the age, gender, highest educational attainment, year of service and civil status. Regression analysis also revealed that workload and peer relationship significantly predict workplace stress, with a variance accounted for 24.1%. Workload contributed a total of 19.3% of the variance in workplace stress and 4.8% for peer relationships and working conditions. This means the heavier the workload, the higher the workplace stress and the better peer relationship and working conditions, the higher the workplace stress. Based on the results, it is recommended that the proposed stress management program be utilized by the selected hospital respondents.Keywords: organizational factors, workplace stress, physical and psychological stress, peer relationship, working condition

Impact of a training project for primary health-care providers (FOCO project) in the HIV screening and HIV late diagnosis

Poster [P043] OBJECTIVE Reducing HIV late diagnosis remains an epidemiological challenge . The objective of this project was to promote early HIV diagnosis through the training of primary health - care providers (PHCP) . METHODS HIV specialists conducted training sessions in 108 primary care centers (PCC) from six Spanish regions during 2016 and 2017 , and with 1804 PHCP involved . The intervention was evaluated using a pre - experimental design collecting the dependent variables both in the six months before and after the intervention . Number of requests for HIV tests from the PCC trained and clinical data of new HIV diagnosed patients were collected . Parametric and non - parametric tests were used to assess differences between pre and post - intervention data . RESULTS 3. Differences in clinical variables in pre and post intervention period

Community-Based Homestay Service: A Proposed Livelihood Project for the Dumagats

The study is founded on a sustainable eco-tourism built on indigenous peoples’ economic empowerment without compromising their cultural heritage. The main objective of the study was to assess the economic viability of the community-based homestay service as a livelihood project to help improve the quality of life of the Dumagats who are native residents of Daraitan. The main service of the project is to provide accommodation and campsite for tourists who usually go for trekking at Mt. Daraitan. The descriptive survey method was employed in this study. Validated survey questionnaires were given out to 430 local and foreign tourists who visited the nature reserve. Data were tabulated and analyzed using the descriptive statistics and financial ratios; such as liquidity ratios, test of return on sales, gross profit ratio, and return on capital. The financial assessment of the homestay service yielded an average of 21.7% return on sales; 83.47% gross profit ratio, and 79.37% return on capital. A portion of the profit will be appropriated for charitable purposes. Mt. Daraitan is one of the to-go-to spots in the Philippines, where nature still can be seen at its most pristine state. Results of financial estimates showed that the economic viability of the project, through development, preservation of the natural architecture of the park, and a livelihood program for the natives that inhabit the area, are very strong reasons to push through with the proposal

Workplace Bullying and Stress among Office Professionals

Workplace bullying has been identified as one of the major contemporary challenges for occupational health and safety and linked to other emerging riskssuch as work-related stress. This study aimed to determine the extent of workplacebullying and stress among office professionals of selected companies andinstitutions in Silang, Cavite and Sta. Rosa, Laguna. The study was conductedamong 102 office professionals using convenience sampling. This correlation studyon workplace bullying and stress were measured using a validated questionnaireadapted from Tabang (2017) and Gumarao (2011), respectively. The resultsrevealed that the overall workplace bullying was perceived to be very low in termsof verbal, nonverbal, psychological, and physical. The stress level of the officeprofessional was also perceived as low. The correlation analysis revealed thatverbal bullying (p=.010), nonverbal bullying (p=.000), psychological bullying(p=.005), and physical bullying (p=.005) were significantly associated with stress.Further results revealed that stress level is significant considering the demographicprofile (age, gender, marital status, educational attainment, length of service, andreligion). However, emotional stress significantly differs by age but not on the othertypes of stress. Recommendations were made to address the issues of bullying andstress in the workplace

Measurement of the [Formula: see text] production cross section in the all-jets final state in pp collisions at [Formula: see text][Formula: see text].

The cross section for [Formula: see text] production in the all-jets final state is measured in pp collisions at a centre-of-mass energy of 8 [Formula: see text] at the LHC with the CMS detector, in data corresponding to an integrated luminosity of 18.4 [Formula: see text]. The inclusive cross section is found to be [Formula: see text] [Formula: see text]. The normalized differential cross sections are measured as a function of the top quark transverse momenta, [Formula: see text], and compared to predictions from quantum chromodynamics. The results are reported at detector, parton, and particle levels. In all cases, the measured top quark [Formula: see text] spectra are significantly softer than theoretical predictions

Multi-center study of inter-rater reproducibility, image quality, and diagnostic accuracy of CZT versus conventional SPECT myocardial perfusion imaging

Cadmium-zinc-telluride (CZT)-based detectors exhibit higher diagnostic sensitivity in myocardial perfusion imaging (MPI) than conventional Anger-MPI for detection of coronary artery disease (CAD); however, reduced specificity and diagnostic accuracy of CZT-MPI were observed. This study aims to compare these different camera systems and to examine the degree of inter-rater reproducibility among readers with varying experience in MPI. 83 patients who underwent double stress/rest examinations using both a CZT and conventional SPECT cameras within one visit were included. Anonymized and randomized MPI-images were distributed to 15 international readers using a standardized questionnaire. Subsequent coronary angiography findings of ten patients served as a reference for analysis of sensitivity and specificity. Image quality was significantly better in CZT-MPI with significantly lower breast attenuation (P < 0.05). CZT-MPI exhibited higher sensitivity than Anger-MPI (87.5% vs. 62.5%) and significantly reduced specificity (40% vs. 100%). Readers experienced with both camera systems had the highest inter-rater agreement indicating higher reproducibility (CZT 0.54 vs. conv. 0.49, P < 0.05). Higher diagnostic sensitivity of CZT-MPI offers advantages in detection of CAD yet potentially of at the cost of reduced specificity, therefore it requires special training and a differentiated evaluation approach, especially for non-experienced readers with such camera systems.
