LAS 3R (REDUCIR-REUTILIZAR-RECICLAR): \ubfSON PRACTICADAS POR DOCENTES UNIVERSITARIOS AL USAR PAPEL EN LAS ACTIVIDADES ACAD\uc9MICAS?

Minimizar los impactos negativos generados al ambiente por sus actividades mediante la ejecuci\uf3n de pr\ue1cticas de consumo responsable, constituye uno de los compromisos ambientales de la universidad. En tal sentido, es importante analizar las pr\ue1cticas de consumo del papel, por parte de los docentes cuando llevan a cabo sus actividades, a fin de diagnosticar si se practica la reducci\uf3n, la reutilizaci\uf3n y el reciclaje de papel. La presente investigaci\uf3n se enmarca dentro del tipo descriptivo, apoyada en un trabajo de campo. La muestra estuvo conformada por 55 docentes universitarios, adscritos al Programa de Licenciatura en Psicolog\ueda de la Universidad Centroccidental Lisandro Alvarado (UCLA). Para el diagn\uf3stico se emple\uf3 un cuestionario validado mediante el juicio de tres expertos. Para el an\ue1lisis de los datos se aplic\uf3 estad\uedstica descriptiva. Los resultados indican que algunas actividades acad\ue9micas a\ufan cuando se llevan a cabo por medios digitales, contin\ufaan generando documentos impresos innecesarios que impiden la reducci\uf3n en el consumo de papel. As\ued mismo, se evidenci\uf3 que la mayor\ueda de los docentes no llevan a cabo pr\ue1cticas de re\ufaso de papel al usar equipos de reproducci\uf3n; y un considerable n\ufamero de ellos no realiza una selecci\uf3n eficiente del papel para ser sometido al proceso de reciclaje. Los resultados obtenidos apoyan la necesidad de ofrecer talleres de educaci\uf3n ambiental a los docentes para coadyuvar en el desarrollo de la competencia laboral de sensibilidad ambiental; as\ued como institucionalizar, en funci\uf3n de las pol\uedticas ambientales de la universidad, la ejecuci\uf3n de medidas que conlleven al consumo responsable del papel. Palabras clave: 3R, consumo de papel, docentes universitarios, responsabilidad ambiental universitaria. ABSTRACT Minimize negative environmental impacts generated by its activities by implementing responsible consumption practices, is one of the environmental commitments of the university. Thus, it is important to analyze the consumption practices of paper by professors when they carry out their activities, in order to diagnose whether they practice the reduction, reuse and recycling of paper. This research is part of a descriptive study, based on a fieldwork. The sample consisted of 55 university professors, assigned to the Psychology Degree Program at Universidad Centroccidental Lisandro Alvarado (UCLA). To carry out the diagnosis was used a questionnaire validated by the judgment of three experts. For data analysis, descriptive statistics were applied. The results indicate that even when some academic activities are carried out by digital media, they continue generating unnecessary printouts that prevent the reduction of paper consumption. It was also evident, that the majority of professors do not perform reuse practices of paper when they use reproduction equipment; and a considerable number of them do not perform an efficient selection of the paper to be submitted to the recycling process. The results support the need for environmental education workshops for professors to assist in the development of labor competence of environmental sensitivity; and institutionalize according to the environmental policies of the university, the implementation of standards that support the responsible paper consumption. KEY WORDS: 3R, paper consumption, university professors, university environmental responsibility.<br

A Social-Ecological View of Barriers and Facilitators for HIV Treatment Adherence: Interviews with Puerto Rican HIV Patients

PURPOSE: To identify perceived barriers and facilitators for HAART adherence among people living with HIV/AIDS in Southern Puerto Rico using a Social Ecological framework. PATIENTS AND METHODS: Individual in-depths interviews were conducted with 12 HIV patients with a history of HAART non-adherence. Interviews were audio-taped and transcribed. Content analysis was performed for each transcribed interview by three independent coders using a codebook. Using Atlas TI, super-codes and families were generated to facilitate the categorization tree as well as grounded analyses and density estimates. RESULTS: Most participants reported a monthly income of $500 or less (n = 7), a high school education level (n = 7), being unemployed (n = 9) and being recipients of government health insurance (n = 11). Three out of six women reported living alone with their children and most men informed living with their parents or other relatives (n = 4). For the grounded analyses, the top four sub-categories linked to high number of quotations were mental health barriers (G = 32) followed by treatment regimen (G = 28), health system (G = 24) and interpersonal relations (G = 16). The top four sub-categories linked to high number of codes are treatment regimen (D = 4), health status perception (D = 3), interpersonal relations (D = 3) and health system (D = 3). CONCLUSION: The results of this study suggest the interconnection of HIV treatment adherence barriers at various system levels. Future studies on HIV treatment barriers should explore these interactions and investigate the possible synergistic effect on non-adherent behavior

Desert plant bacteria reveal host influence and beneficial plant growth properties

Deserts, such as those found in Saudi Arabia, are one of the most hostile places for plant growth. However, desert plants are able to impact their surrounding microbial community and select beneficial microbes that promote their growth under these extreme conditions. In this study, we examined the soil, rhizosphere and endosphere bacterial communities of four native desert plants Tribulus terrestris, Zygophyllum simplex, Panicum turgidum and Euphorbia granulata from the Southwest (Jizan region), two of which were also found in the Midwest (Al Wahbah area) of Saudi Arabia. While the rhizosphere bacterial community mostly resembled that of the highly different surrounding soils, the endosphere composition was strongly correlated with its host plant phylogeny. In order to assess whether any of the native bacterial endophytes might have a role in plant growth under extreme conditions, we analyzed the properties of 116 cultured bacterial isolates that represent members of the phyla Proteobacteria, Bacteroidetes, Actinobacteria and Firmicutes. Our analysis shows that different strains have highly different biochemical properties with respect to nutrient acquisition, hormone production and growth under stress conditions. More importantly, eleven of the isolated strains could confer salinity stress tolerance to the experimental model plant Arabidopsis thaliana suggesting some of these plant-associated bacteria might be useful for improving crop desert agriculture

Preferences, use of and satisfaction with mental health services among a sample of Puerto Rican cancer patients

OBJECTIVE: The purpose of this study was to describe the preferences, the use, satisfaction of mental health services (MHS) among a sample of Puerto Rican patients with cancer undergoing oncology treatment. METHODS: A convenience sample of 120 patients diagnosed with cancer was recruited. Self-report questionnaires assessed socio-demographic and background questions, and the Mental Health Service Preference, Utilization and Satisfaction Questionnaire (MHSPUS). The Socio-demographic and Background Questionnaire inquired about participants\u27 demographic and socioeconomic characteristics, and included questions such as history of psychiatric diagnosis and spiritual practices. Univariate and Chi square analyses were used for descriptive purposes. Logistic regressions were used to explore associations between sociodemographic factors and MHS preferences and use. RESULTS: The majority of the sample were females (53.8%), 61 and older (53.8%), and married or living with partner (57.1%), and reported an income equal to or less than $12,000 per year (44.4%), which places them under the US federal poverty line. Most of the participants (66.7%) reported being receptive to seeking services. Findings showed a significant association between living situation and past (p \u3c .05) and lifetime use (p \u3c .05) of MHS and past use of MHS. Participants living alone were more like to have used MHS in the past and during their lifetime. Adjusted logistic regression analyses revealed that living with someone was a protective factor for not using MHS in their lifetime (OR = 0.28; C1 = 0.08-0.95). Participants preferred to receive MHS at the oncology clinic, preferably on the date of their oncology appointments and during morning hours. CONCLUSION: Findings support the integration of mental health services within the oncology practice setting

Evaluation of Cellulolytic and Hemicellulolytic Abilities of Fungi Isolated from Coffee Residue and Sawdust Composts

This study focused on the evaluation of cellulolytic and hemicellulolytic fungi isolated from sawdust compost (SDC) and coffee residue compost (CRC). To identify fungal isolates, the ITS region of fungal rRNA was amplified and sequenced. To evaluate enzyme production, isolates were inoculated onto wheat bran agar plates, and enzymes were extracted and tested for cellulase, xylanase, β-glucanase, mannanase, and protease activities using different azurine cross-linked (AZCL) substrates. In total, 18 isolates from SDC and 29 isolates from CRC were identified and evaluated. Four genera (Aspergillus, Galactomyces, Mucor, and Penicillium) and five genera (Aspergillus, Coniochaeta, Fusarium, Penicillium, and Trichoderma/Hypocrea) were dominant in SDC and CRC, respectively. Penicillium sp., Trichoderma sp., and Aspergillus sp. displayed high cellulolytic and hemicellulolytic activities, while Mucor isolates exhibited the highest β-glucanase and mannanase activities. The enzyme analyses revealed that Penicillium, Aspergillus, and Mucor isolates significantly contributed to the degradation of SDC, whereas Penicillium, Aspergillus, and Trichoderma isolates had a dominant role in the degradation of CRC. Notably, isolates SDCF5 (P. crustosum), CRCF6 (P. verruculosum), and CRCF2 and CRCF16 (T. harzianum/H. lixii) displayed high activity regarding cellulose and hemicellulose degradation, which indicates that these species could be beneficial for the improvement of biodegradation processes involving lignocellulosic materials

Physical properties of homogeneous particleboard based on acacia tree and polyurethane adhesive as a resins

The formaldehyde-based adhesives have always been chosen for manufacturer in the making of particleboard because of the cost. However, it has low moisture resistance and high water absorption. At the same time, formaldehyde-based adhesive also produced gaseous emission that can cause cancer and bronchial health. Meanwhile, the high water resistance, low moisture content and healthy to the human body nowadays becomes most important issues in the making of furniture for market. This research was discusses on the ability of Acacia tree as raw material and polyurethane (PU) as an adhesive for making the homogeneous particleboard. The aim of this research isto looking the impact of using different particle sizes from Acacia tree to the physical properties of the end product. This study also focuses on the potential of paraffin wax as a water repellent agent. The testing of physical properties was includes the thickness swelling (TS) testing, moisture content (MC), density and water absorption (WA testing). The size of Acacia particle was varied from xx>2mm and x>4mm. All particleboards produced was achieve the range of medium density according to the Japan Industry Standard (JIS). The results have shown that the value of the density and the particle size was influenced the result especially for the physical properties. From this research it is proved that the PU as a resin and sawdust of acacia tree with some specific size can be a good binder and material for the particle board industries in future. The paraffin wax also showed a great potential as a water repellent agent based on the reduction of water absorption of the particleboard. The particleboard with sizes between 2mm to 4mm proves better results compared to the smaller or bigger sizes of particle

Brief Report: Hispanic Patients\u27 Trajectory of Cancer Symptom Burden, Depression, Anxiety, and Quality of Life

Background: Anxiety and depression symptoms are known to increase cancer symptom burden, yet little is known about the longitudinal integrations of these among Hispanic/Latinx patients. The goal of this study was to explore the trajectory and longitudinal interactions among anxiety and depression, cancer symptom burden, and health-related quality of life in Hispanic/Latinx cancer patients undergoing chemotherapy. METHODS: Baseline behavioral assessments were performed before starting chemotherapy. Follow-up behavioral assessments were performed at 3, 6, and 9 months after starting chemotherapy. Descriptive statistics, chi-square tests, Fisher\u27s exact tests, and Mann-Whitney tests explored associations among outcome variables. Adjusted multilevel mixed-effects linear regression models were also used to evaluate the association between HADS scores, follow-up visits, FACT-G scale, MDASI scale, and sociodemographic variables. RESULTS: Increased cancer symptom burden was significantly related to changes in anxiety symptoms\u27 scores (adjusted beta^ = 0.11 [95% CI: 0.02, 0.19]. Increased quality of life was significantly associated with decreased depression and anxiety symptoms (adjusted beta^ = -0.33; 95% CI: -0.47, -0.18, and 0.38 adjusted beta^= -0.38; 95% CI: -0.55, -0.20, respectively). CONCLUSIONS: Findings highlight the need to conduct periodic mental health screenings among cancer patients initiating cancer treatment
