The Politics and Materiality of Coordination: Philippine Village Leaders Responding to the Spread of a Global Plant Disease in Banana

Leadership is the process of directing and influencing, and it involves taking actions and producing change, in both informal and formal settings. In the Philippines, there are village leaders elected in a political position. Barangays (villages) are the smallest political administrative unit in the country and are led by a barangay captain. This paper investigates leadership, not only as an exclusive result of politics and social structures, but relates it to the problem-solving practices and managing interdependencies modified by a global plant disease in banana. The Philippine banana industry caters to both domestic and export markets, making it an important economic commodity. A virulent global plant disease in banana, Fusarium oxysporum f.sp. cubense Tropical Race 4 (Foc TR4), is threatening the producers in Philippine villages. Case studies of village leaders examine their actions in relation to nonconstituents, particularly with the Foc threat. Settings were four villages where export-oriented banana companies were present, mingling with local players. The common denominators in all these villages were the presence of export-oriented banana plantation and recorded incidence of Foc. The village leaders’ handling of the gravity and importance of problem still leaned largely on how their political influencers perceived the problem. The multinational companies, on the other hand, were not able to fully articulate the importance of the problem to the village leaders. These companies kept much of their researches and studies to themselves and shared only what was necessary. As a result, the village did not have complete information on how to treat or understand the problem

Coordination and Risk in the Philippine Banana Industry: Conditions for Responding to Panama Disease

Fusarium oxysporum f.sp. cubense Tropical Race 4 is a disease that traverses political, economic, geographical, and social boundaries and confronts the fragmented and highly polarized banana industry. Furthermore, the nature of TR4 has many uncertainties and unknowns. This paper investigated conditions for coordination in responding to TR4 risk. A qualitative case study of two villages in Davao del Norte, a major producing area in the Philippines with TR4 occurrence, was done to provide a contextual and in-depth analysis. Results showed that there was coordination between actors with longer working or personal relationships. They shared a common language for identifying problems and defining risks and communicate beyond the boundaries of their own organizations. There were visible signs of alliances between private and public domains in their handling of TR4 uncertainties. Actors have an urgency to react to TR4 impacts by accommodating multiple solutions. The enabling conditions for coordination identified were long-term relations forged outside the organizations/industry alliances and examination and the recognition of unknown TR4 characteristics, thus forging emerging research and information sharing. The constraints included polarization rooted from unequal access to land, blaming, and the isolated experiments and advocacy for single solutions. In conclusion, there was low coordination in responding to disease risk because of the blaming and diversities in solutions. However, there was an emerging coordination that built on social relations and deliberate efforts to bring parties together from the public and private sectors. The industry has to adapt, settle, and manage its differences to collectively address the banana disease risk

Closing the cycle for the cut rose industry by the reuse of its organic wastes: A case study in Ecuador

The soil conditions and the yield and quality of Rosa sp. var. Freedom were determined following the incorporation into the soil of rose waste composts, with or without fertigation; the effects of these treatments were compared with those of non-stabilised chopped rose wastes þ fertigation (FWF). The growing conditions were those of a commercial greenhouse. The use of the composts, alone or combined with fertigation, increased the available P and K contents of the soil with respect to FWF. However, only the compost þ fertigation treatments improved, in general, the soil fertility regarding the organic matter (OM), nitrogen and available micronutrient concentrations, in comparison to FWF. When the composts were added alone, irrigation with alkaline water increased the soil pH and, in consequence, reduced the availability of micronutrients. Overall, the combined use of compost and fertigation increased the cut rose yield and quality relative to the application of compost alone and FWF. Principal component analysis indicated that the OM, available Cu, Mn and Zn and total N contents and the pH of the soil were the principal soil parameters determining the yield and quality of the roses. This analysis classified the treatments in three groups: the compost þ fertigation treatments; the treatments with compost alone; and the FWF treatment. The compost þ fertigation treatments gave the highest net income (average for these treatments ¼ 80388.92 US dollars ha 1). Therefore, the compost þ fertigation treatments were highly beneficial with regard to increasing soil fertility and cut rose yield, quality and profitability

Supervision of milk coagulation with scatter red LED light

For cheese production clotting time is prederteminated using a proteolytic enzyme titulation test (Chamorro and Losada 2002). Thus an expert operator decides the optimum cutting time (always delayed compared to clotting time) based on his own subjective evaluation of textural and visual properties of the curd (Castillo et al. 2000). Expert judgment usually gives acceptable results, yet variability in the optimal assessment of cutting time leads to affects further cheese processing operations (pressing and ripening). The aforementioned reasons suggest the importance of an objective and non-destructive method to determinate optimal cutting time, which would allow indeed the automatic supervision of the cheese clotting process. The goal of this work is a prospective study for the supervision of milk coagulation with scatter red LED light

Solar Neutrinos Before and After KamLAND

We use the recently reported KamLAND measurements on oscillations of reactor anti-neutrinos, together with the data of previously reported solar neutrino experiments, to show that: (1) the total 8B neutrino flux emitted by the Sun is 1.00(1.0 \pm 0.06) of the standard solar model (BP00) predicted flux, (2) the KamLAND measurements reduce the area of the globally allowed oscillation regions that must be explored in model fitting by six orders of magnitude in the Delta m^2-tan^2 theta plane, (3) LMA is now the unique oscillation solution to a CL of 4.7sigma, (4) maximal mixing is disfavored at 3.1 sigma, (5) active-sterile admixtures are constrained to sin^2 eta<0.13 at 1 sigma, (6) the observed ^8B flux that is in the form of sterile neutrinos is 0.00^{+0.09}_{-0.00} (1 sigma), of the standard solar model (BP00) predicted flux, and (7) non-standard solar models that were invented to completely avoid solar neutrino oscillations are excluded by KamLAND plus solar at 7.9 sigma . We also refine quantitative predictions for future 7Be and p-p solar neutrino experiments.Comment: Published version, includes editorial improvement

Cianobacterias de Humedales de Altura del Noroeste Argentino

La variabilidad latitudinal y altitudinal de nuestro país posibilita la existencia de una diversidad de humedales que, en sentido amplio, incluyen marismas, pantanos y turberas o superficies cubiertas de aguas estancadas o fluyentes, permanentes o temporales, naturales o artificiales, dulces, salobres o saladas, e inclusive extensiones de agua marina cuya profundidad no exceda los seis metros en bajamar. El objetivo de este trabajo fue aportar al conocimiento de las cianobacterias en humedales de altura del Noroeste Argentino. Se realizó un muestreo estival interdisciplinario del 21 de enero al 01 de febrero de 2005 que abarcó el censo de veintiséis lagunas correspondientes a las provincias de Jujuy, Salta y Catamarca. Las muestras cualitativas se obtuvieron mediante el filtrado de 25 litros de agua a través de una red de plancton de 20 µm de poro. Las mismas fueron fijadas in situ con formaldehído al 4% y observadas bajo microscopio binocular con dispositivo para dibujo. De acuerdo a los resultados obtenidos la taxocenosis estuvo integrada por 23 taxones, en su mayoría cosmopolitas y de medios salobres, pertenecientes a Chroococcales (5), Nostocales (3) y Oscillatoriales (15). Phormidium inundatum es señalado por primera vez para el Noroeste Argentino y además de dicha especie son nuevas citas Merismopedia glauca, M. punctata, Synechococcus elongatus, Anabaena variabilis, Nodularia spumigena, Nostoc linckia, Leptolyngbya fragilis, Spirulina major, Phormidium autumnale, P. breve y P. molle para Catamarca.Fil: Mirande, Virginia.

Interleukin (IL)-17A and IL-17F and asthma in Saudi Arabia: mRNA transcript levels and gene polymorphisms

Asthma is a multifactorial disorder and both genetic and environmental factors contribute to its development. The present study explored cytokines interleukin (IL)-17A and IL17F levels as usable parameters for the diagnosis of asthmatics Saudi patients. Blood samples were collected from 100 asthma patients and 100 matched controls. The transcript mRNA levels in whole blood were determined by real-time reverse-transcription polymerase chain reaction. Expression studies showed that levels of IL17A and IL17F were significantly higher in asthma patients compared to controls [IL17A: 1.112 (2.088) vs 0.938 (1.363)]; IL17F: 0.707 (1.33) vs 0.667 (0.590). The mRNA transcripts of IL17A and IL17F were positively and significantly correlated in all subjects examined in this study: controls as well as asthma patients (r = 0.455, P &lt; 0.01 for controls and r = 0.644, P &lt; 0.01 for patients). These findings suggest that asthma is characterized by an elevation of cytokines IL17A and IL17F and the measurement of their expression can be a valuable parameter for the diagnosis of asthma.Keywords: Asthma, interleukin-17F (IL17F), interleukin-17A (IL17A), gene expression, real time-polymerase chain reaction (RT-PCR), Saudi Arabia.African Journal of Biotechnology Vol. 12(23), pp. 3615-362

Real-world outcomes of sipuleucel-T treatment in PROCEED, a prospective registry of men with metastatic castration-resistant prostate cancer.

BackgroundThe large registry, PROVENGE Registry for the Observation, Collection, and Evaluation of Experience Data (PROCEED)(NCT01306890), evaluated sipuleucel-T immunotherapy for asymptomatic/minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC).MethodsPROCEED enrolled patients with mCRPC receiving 3 biweekly sipuleucel-T infusions. Assessments included overall survival (OS), serious adverse events (SAEs), cerebrovascular events (CVEs), and anticancer interventions (ACIs). Follow-up was for ≥3&nbsp;years or until death or study withdrawal.ResultsIn 2011-2017, 1976 patients were followed for 46.6&nbsp;months (median). The median age was 72&nbsp;years, and the baseline median prostate-specific antigen level was 15.0&nbsp;ng/mL; 86.7% were white, and 11.6% were African American. Among the patients, 1902 had 1 or more sipuleucel-T infusions. The median OS was 30.7&nbsp;months (95% confidence interval [CI], 28.6-32.2&nbsp;months). Known prognostic factors were independently associated with OS in a multivariable analysis. Among the 1255 patients who died, 964 (76.8%) died of prostate cancer (PC) progression. The median time from the first infusion to PC death was 42.7&nbsp;months (95% CI, 39.4-46.2&nbsp;months). The incidence of sipuleucel-T-related SAEs was 3.9%. The incidence of CVEs was 2.8%, and the rate per 100 person-years was 1.2 (95% CI, 0.9-1.6). The CVE incidence among 11,972 patients with mCRPC from the Surveillance, Epidemiology, and End Results-Medicare database was 2.8%; the rate per 100 person-years was 1.5 (95% CI, 1.4-1.7). One or more ACIs (abiraterone, enzalutamide, docetaxel, cabazitaxel, or radium 223) were received by 77.1% of the patients after sipuleucel-T; 32.5% and 17.4% of the patients experienced 1- and 2-year treatment-free intervals, respectively.ConclusionsPROCEED provides contemporary survival data for sipuleucel-T-treated men in a real-world setting of new life-prolonging agents, which will be useful in discussing treatment options with patients and in powering future trials with sipuleucel-T. The safety and tolerability of sipuleucel-T in PROCEED were consistent with previous findings
