Capacity accumulation in three natural resource-based industries in Chile: the shifting roles and positions of doctoral graduates

Understanding technical change in late industrialised economies is the general area of this thesis. There is a lack of research and policy advice on how industry sectors develop active technological learning, particularly in economies based on natural resources and in contexts of poverty and inequality. The thesis is framed by the challenges related to production and economic performance. This thesis compares three natural resource-based industries in Chile - copper mining, fruit growing and salmon farming – focusing on the participation of doctoral graduates, taking a historical perspective. Doctoral graduates represent a small fraction of the population, but their importance in the advancement of knowledge and technological change is considered strategic. The thesis research questions are: how do doctoral graduates participate in the accumulation of producer capabilities in industry sectors; what factors are important for their participation; and what are the implications for public policy? The thesis adopts the concept Sectoral Learning Systems (SLS) (adapted from Viotti, 2001) and applies the producer capability approach (von Tunzelmann and Wang, 2007; von Tunzelmann, 2009), which is an alternative approach to conventional production theory, to understand the practice of doctoral graduates in relation to technological change. Policy analysis and recommendations are based on the concept of system alignment (von Tunzelmann, 2010), which offers possibilities for governing systems in which agents may have contradictory views and positions. Throughout, the thesis is underpinned by Bourdieu’s (2005) economic anthropological approach. His notions of field, habitus and capital are reinterpreted within the more specific science, technology and innovation studies literature. This thesis constitutes an interdisciplinary endeavour that integrates approaches from different academic traditions such that all are essential for achieving the research findings. In terms of methodology, the thesis draws on a historical study of coevolution of technology and governance for each of the three industries, complemented by in depth individual case studies. Through analytical inference, I locate doctoral graduates in the history of each field. The analysis is illustrated by the case studies of doctoral graduates’ careers. By applying the producer capability approach, I deduce the likely accumulation of scientific capabilities by doctoral graduates in each field. The results of the comparison show that copper mining, fruit growing and salmon farming display similar patterns of development in relation to their respective incorporations into the technological revolutions in each industry field. In all three cases, the state played an important role in the emergence of these industries at the national and international levels. The establishment of these industries was succeeded by periods of high profits, adoption of new technologies and low levels of innovation, followed by intense process innovation and increasing competition, and finally a period of concentration and re-structuring characterized by the development of networks of suppliers and oligopolistic industry structures. Product diversification in the dominant technological paradigm appeared towards the last period. Doctoral graduates emerged as scientific suppliers to the industries, when these industries embarked on the phase of intense process innovation, which increased demand for scientific possibilities supplied by doctoral graduates. The level of demand often was related to industry subsidies, particularly important in the fruit and salmon farming sectors. Doctoral graduates participated in active technological learning in less mature technology contexts, and in systems where the dominant producers had the capabilities for improvement and innovation. Once doctoral graduates had a position as scientific suppliers, they actively maintained and enhanced their participation in the field. Doctoral graduates also participated in shaping the structure of the fields, and in influencing policy. The thesis derives policy recommendations to strengthen active learning, particularly in relation to new product development, based on the understandings and the lessons drawn from history

Implementación de una Jefatura de relaciones públicas en la Cruz Roja Ecuatoriana de la ciudad de Milagro.

En el Ecuador la sociedad establece y mantiene un nivel social variable, en donde nosotros cómo individuos estamos dispuesto a mantener una relación personal con todos y sin discriminaciones. Las Jefaturas de Relaciones Públicas han logrado dentro de los medios que los individuos se informen de manera directa de los aconteceres que se proporcionan día a día en nuestra vida cotidiana. Las Relaciones Públicas han hecho que las personas puedan satisfacer sus curiosidades y necesidades tanto en el campo laboral como el informal, es así que muchas de las instituciones del estado principalmente las del área de la salud, deberían contar con una Jefatura de Relaciones Públicas para que puedan darse a conocer internamente, una de ella es la Cruz Roja del cantón Milagro, es por ello que tememos la necesidad de implementar ésta dependencia para que la sociedad esté dispuesta a ayudar y ser ayudadas, la comunidad en general se vería beneficiada con el desarrollo de sus funciones y así ser reconocida en amplios sectores de la localidad, superando el poco interés de la ciudadanía o cada una de las acciones o programas que desarrolla ésta noble institución

Functional diversity of phytochrome family in the control of light and gibberellin-mediated germination in Arabidopsis

In several species, seed germination is regulated by light in a way that restricts seedling emergence to the environmental conditions that are likely to be favourable for the success of the new individual, and therefore, this behaviour is recognized to have adaptive value. The phytochromes are one of the most relevant photoreceptors involved in light perception by plants. We explored the redundancy and diversity functions of the phytochrome family in the control of seed responsiveness to light and gibberellins (GA) by using a set of phytochrome mutants of Arabidopsis. Our data show that, in addition to the well-known role of phyB in the promotion of germination in response to high red to far-red ratios (R/FR), phyE and phyD stimulate germination at very low R/FR ratios, probably by promoting the action of phyA. Further, we show that phyC regulates negatively the seed responsiveness to light, unravelling unexpected functions for phyC in seed germination. Finally, we find that seed responsiveness to GA is mainly controlled by phyB, with phyC, phyD and phyE having relevant roles when acting in a phyB-deficient background. Our results indicate that phytochromes have multiple and complex roles during germination depending on the active photoreceptor background.Estación Experimental Agropecuaria BarilocheFil: Arana, María Veronica.

Aspectos responsables en la experimentación con animales en medicina

Los animales son las principales víctimas de la historia, esto fue mencionado por primera vez en el texto descrito por Peter Singer La liberación animal. Enfocarse en una ética para el bienestar animal implica situar la mirada en la capacidad de sentir qué experimentan los animales. El bienestar animal es la capacidad de los animales de sentir dolor, sufrimiento, es decir, experimentan emociones.La experimentación animal no es un tema reciente, es un problema que ha existido desde hace muchos años. Un pilar fundamental es el comité de ética institucional, su función es evaluar cada paso antes, y durante la experimentación, verificando el programa, procedimiento, justificación, bienestar, ofrecer un digno y adecuado alojamiento que sea confortable. Cualquier experimentación con animales debe tener una justificación científica, evitar el dolor, sufrimiento, así como tener personal capacitado para salvaguardar su bienestar

Safety and effectiveness of RBD-specific polyclonal equine F(ab´)2 fragments for the treatment of hospitalized patients with severe Covid-19 disease: A retrospective cohort study

Background Passive immunotherapy has been evaluated as a therapeutic alternative for patients with COVID-19 disease. Equine polyclonal immunotherapy for COVID-19 (EPIC) showed adequate safety and potential efficacy in a clinical trial setting and obtained emergency use authorization in Argentina. We studied its utility in a real world setting with a larger population. Methods We conducted a retrospective cohort study at “Hospital de Campaña Escuela-Hogar" (HCEH) in Corrientes, Argentina, to assess safety and effectiveness of EPIC in hospitalized adults with severe COVID-19 pneumonia. Primary endpoints were 28-days all-cause mortality and safety. Mortality and improvement in modified WHO clinical scale at 14 and 21 days were secondary endpoints. Potential confounder adjustment was made by logistic regression weighted by the inverse of the probability of receiving the treatment (IPTW) and doubly robust approach. Findings Subsequent clinical records of 446 non-exposed (Controls) and 395 exposed (EPIC) patients admitted between November 2020 and April 2021 were analyzed. Median age was 58 years and 56.8% were males. Mortality at 28 days was 15.7% (EPIC) vs. 21.5% (Control). After IPTW adjustment the OR was 0.66 (95% CI: 0.46–0.96) P = 0.03. The effect was more evident in the subgroup who received two EPIC doses (complete treatment, n = 379), OR 0.58 (95% CI 0.39 to 0.85) P = 0.005. Overall and serious adverse events were not significantly different between groups. Conclusions In this retrospective cohort study, EPIC showed adequate safety and effectiveness in the treatment of hospitalized patients with severe SARS-CoV-2 disease.Fil: Farizano Salazar, Diego H..

Sonographic assessment of abdominal fat distribution in infancy

There is growing evidence that not only the total amount of fat, but also the distribution of body fat determines risks for metabolic and cardiovascular disease. Developmental studies on factors influencing body fat distribution have been hampered by a lack of appropriate techniques for measuring intraabdominal fat in early life. Sonography, which is an established method for assessing abdominal fat distribution in adults, has not yet been evaluated in infants. To adapt the sonographic measurement of abdominal fat distribution to infants and study its reliability. The Generation R study, a population-based prospective cohort study. We included 212 one- and 227 two-year old Dutch infants in the present analysis. Sixty-two infants underwent replicate measurements to assess reproducibility. We developed a standardized protocol to measure the thickness of (1) subcutaneous and (2) preperitoneal fat in the upper abdomen of infants. To this end we defined infancy specific measurement areas to quantify fat thickness. Reproducibility of fat measurements was good to excellent with intraclass correlation coefficients of 0.93–0.97 for intra-observer agreement and of 0.89–0.95 for inter-observer agreement. We observed a pronounced increase in preperitoneal fat thickness in the second year of life while subcutaneous fat thickness increased only slightly, resulting in an altered body fat distribution. Gender did not significantly influence fat distribution in the first two years of life. Our age specific protocol for the sonographic measurement of central subcutaneous and preperitoneal fat is a reproducible method that can be instrumental for investigating fat distribution in early life

City of Hitchcock Comprehensive Plan 2020-2040

Hitchcock is a small town located in Galveston County (Figure 1.1), nestled up on the Texas Gulf Coast. It lies about 40 miles south-east of Houston. The boundaries of the city encloses an area of land of 60.46 sq. miles, an area of water of 31.64 sq. miles at an elevation just 16 feet above sea level. Hitchcock has more undeveloped land (~90% of total area) than the county combined. Its strategic location gives it a driving force of opportunities in the Houston-Galveston Region.The guiding principles for this planning process were Hitchcock’s vision statement and its corresponding goals, which were crafted by the task force. The goals focus on factors of growth and development including public participation, development considerations, transportation, community facilities, economic development, parks, and housing and social vulnerabilityTexas Target Communitie

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. // Methods: We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung's disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. // Findings: We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung's disease) from 264 hospitals (89 in high-income countries, 166 in middle-income countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in low-income countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. // Interpretation: Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between low-income, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
