Investigar problemas ambientales en Antropología Social Pertinencia Social y Científica: una aproximación al campo. En: Avá, nº 18

Este texto abordará la importancia de la investigación de problemas ambientales en antropología social. Podemos afirmar que la relación entre sociedad y naturaleza se ha mantenido como tema de interés desde los inicios de la antropología como disciplina, primeramente, con aportes desde el determinismo ambiental, y luego, con estudios sobre la etnociencia, las clasificaciones y conocimiento de la flora y fauna (Conklin, 955; Berlin, 1973), la adaptación ecológica y ecosistemas (Steward, 1968; Rappaport, 1968), y la relación entre hombres y otras especies (White, 1949; Ingold, 1986; Haraway, 2003; Raffles, 2010). Este interés se ha acentuado en las últimas décadas al incrementar la atención en la situación climática, la crisis ecológica y los problemas ambientales Haenn & Wilk, 2006) que han dado un giro a la forma en que experimentamos nuestro entorno, así como en las construcciones y entendimientos de estos problemas

How Nervous Should Your Cybersecurity Team Be When the Gen-Z Population Joins the Workforce over the Next Few Years?

UD’s Center for Cybersecurity & Data Intelligence did a small study in March 2018 that explored how the different generations encounter cybersecurity awareness and practices. A key group that we analyzed was Generation Z (Gen-Z). these are the kids now in high school that will soon be entering college and the broader workforce. Our study applied our Cyber-Mindfulness model to our analysis of the various generations - from Baby Boomers & Gen X-ers to Millennials and Gen Z. Using both our original data and existing data sources, we were able to craft descriptive profiles of the generational differences with regard to cybersecurity attitudes and behaviors. It is really interesting to see the differences in generations and how these Gen-Z students are going to bring a very disruptive set of expectations and new behaviors to both college and career

Developing, Adopting, and Executing 100% Net-Renewable Electricity Resolutions at the Local Level

In the absence of national leadership on climate policy, municipalities are adopting resolutions to reduce their carbon footprint and transition to clean energy. However, what leads to successful adoption of these resolutions and how to effectively implement climate goals at the community level needs further exploration. To investigate these questions, this thesis examines the resolutions adopted in Salt Lake City, Park City, and Moab, Utah to transition to 100% renewable electricity by 2032. Data was collected through documents, such as city reports and newspapers, and interviews with government officials, city staff, and community members involved with the resolution process. A time series analysis and thematic analysis were used to determine casual events and identify fundamental themes within the data. Each city’s plan for resolution execution was compared to the approaches and techniques outlined in the community-based social marketing framework and the theory of diffusion of innovations. These findings deliver a transferable five-step framework to assist other cities in adopting similar resolutions and strategies to engage community members with practices that will help cities achieve these ambitious resolutions

The Diffusion of Innovations: A Review and Explication of Central Concepts

The study of the diffusion of innovations attempts to understand how new things or ideas, after a period of time, become widely adopted throughout a group or society. Everett Rogers (1983), one of the pioneers in this area of research, sees the diffusion process as essential to understanding social change. Diffusion, as Rogers sees it, is essentially a communication activity. Accordingly, social change consists of the introduction of something new - invention, followed by the process of diffusing the invention - this is done through all forms of communication, and finally the process ends with some type of consequence, or effect. The largest body of research in this area focuses on the adoption of new farming methods. The need to expand crop yields for a growing world population has been a primary goal of many nations. At the same time, farmers work their fields with numerous threats to their livelihood - bad weather, disease, and drought - they are not likely to add to that risk by going with new or unproven ideas. However, they have adopted new ideas over time, so studying the process and in turn, speeding-up the channels in that process, has proved to be quite successful

Planning for Technology-Enhanced Learning on Residential Campuses

While many institutions are feverishly designing and assembling distance-learning courses for delivery of off-site degree programs, even more are wondering how best to create and execute technology plans for their residential campuses. Planning and implementing a sustainable infrastructure requires a widely shared vision that speaks directly to your mission, plenty or money and strong leadership that ranges from student ranks up through your board of trustees

Is Your Organization Cyber-Mindful?

Let’s face it, cybersecurity isn’t going to get any easier in 2018. As long as there is a financial or geo-political incentive, the threats will keep coming and the level of exploit sophistication will keep rising. Winning this battle truly requires a change in our approach. If you have been scanning the popular media or reading our professional publications, you’ll notice that the attack vectors are shifting from technical exploits to human vulnerabilities. Like most businesses, even the bad guys are striving to be more efficient, and it is very cost-effective to socially-engineer a way into your system rather than deploying a technical exploit. Thus, in addition to maintaining our technical vigilance, we now must strengthen our cybersecurity awareness training just to keep up with the bad guys. Cybersecurity “human factors” is an area that many organizations are not fully prepared to do effectively

Contemporary paradigm for the evaluation and treatment of hereditary gastric cancer

Gastric cancer is the third leading cause of cancer mortality worldwide. Survival is linked to stage at diagnosis and tolerance to surgery and adjuvant therapy. The emergence of sophisticated methods to identify patients at high risk for the development of gastric cancer has given us an opportunity to eliminate a lethal disease in an identifiable patient population. Guidelines and recommendations have been established and prophylactic total gastrectomy is considered the most effective treatment. However, this requires substantial physical and emotional investment. It is imperative that patients and families are supported by genetic counseling, ongoing surveillance, and survivorship studies

Chlorophyll f and chlorophyll d are produced in the cyanobacterium Chlorogloeopsis fritschii when cultured under natural light and near-infrared radiation

We report production of chlorophyll f and chlorophyll d in the cyanobacterium Chlorogloeopsis fritschii cultured under near-infrared and natural light conditions. C. fritschii produced chlorophyll f and chlorophyll d when cultured under natural light to a high culture density in a 20 L bubble column photobioreactor. In the laboratory, the ratio of chlorophyll f to chlorophyll a changed from 1:15 under near-infrared, to an undetectable level of chlorophyll f under artificial white light. The results provide support that chlorophylls f and d are both red-light inducible chlorophylls in C. fritschii

Murine study of portal hypertension associated endothelin-1 hypo-response

AIM: To investigate endothelin-1 hypo-responsive associated with portal hypertension in order to improve patient treatment outcomes. METHODS: Wild type, eNOS(-/-) and iNOS(-/-) mice received partial portal vein ligation surgery to induce portal hypertension or sham surgery. Development of portal hypertension was determined by measuring the splenic pulp pressure, abdominal aortic flow and portal systemic shunting. To measure splenic pulp pressure, a microtip pressure transducer was inserted into the spleen pulp. Abdominal aortic flow was measured by placing an ultrasonic Doppler flow probe around the abdominal aorta between the diaphragm and celiac artery. Portal systemic shunting was calculated by injection of fluorescent microspheres in to the splenic vein and determining the percentage accumulation of spheres in liver and pulmonary beds. Endothelin-1 hypo-response was evaluated by measuring the change in abdominal aortic flow in response to endothelin-1 intravenous administration. In addition, thoracic aorta endothelin-1 contraction was measured in 5 mm isolated thoracic aorta rings ex-vivo using an ADI small vessel myograph. RESULTS: In wild type and iNOS(-/-) mice splenic pulp pressure increased from 7.5 ± 1.1 mmHg and 7.2 ± 1 mmHg to 25.4 ± 3.1 mmHg and 22 ± 4 mmHg respectively. In eNOS(-/-) mice splenic pulp pressure was increased after 1 d (P = NS), after which it decreased and by 7 d was not significantly elevated when compared to 7 d sham operated controls (6.9 ± 0.6 mmHg and 7.3 ± 0.8 mmHg respectively, P = 0.3). Abdominal aortic flow was increased by 80% and 73% in 7 d portal vein ligated wild type and iNOS when compared to shams, whereas there was no significant difference in 7 d portal vein ligated eNOS(-/-) mice when compared to shams. Endothelin-1 induced a rapid reduction in abdominal aortic blood flow in wild type, eNOS(-/-) and iNOS(-/-) sham mice (50% ± 8%, 73% ± 9% and 47% ± 9% respectively). Following portal vein ligation endothelin-1 reduction in blood flow was significantly diminished in each mouse group. Abdominal aortic flow was reduced by 19% ± 9%, 32% ± 10% and 9% ± 9% in wild type, eNOS(-/-) and iNOS(-/-) mice respectively. CONCLUSION: Aberrant endothelin-1 response in murine portal hypertension is NOS isoform independent. Moreover, portal hypertension in the portal vein ligation model is independent of ET-1 function
