Delimitation of the Right to Life by Healthcare Professionals: Up to what point should the right to life be protected?

This article explores the medical care standard required by law for terminally illpatients and the possibility of limiting therapeutic efforts while respecting the duediligence expected from doctors. To this end, circumstances are identified in whichthe doctor is forced to choose between two possible actions: to guarantee the right tolife by continuing treatment, or to limit the right to healthcare by limiting therapeuticefforts. Two cases taken from English Common Law were reviewed that decided onthe factual problem at hand. In our country, the Constitutional Court established aline of jurisprudence on the role of the doctor in deciding whether or not to continuetreatment for a terminally ill person. Lastly, jurisprudence precedents are presentedalong with a comparative analysis of the solutions given in Great Britain andin Colombia.

Primary Prevention and Screening Strategies for Colorectal Cancer: Which Strategy Should Take?

Objective: To explore and define the utility of different strategies for primary prevention (ASA, diet, physical activity) and strategies of screening test (FOBT, sigmoidoscopy, colonoscopy, etc.) for colorectal cancer. Data source: Databases consulted were MEDLINE (1966 to 2006), DARE (1980 to 2006), Cochrane Central Register of Controlled Trials, Cochrane Collaboration’s Registry of Clinical Trials, Cochrane Database of Systematic Reviews and LILACS. Study selection: Studies such clinical trial, cohort and case-control studies of the effectiveness of tests for screening and primary prevention adenoma and colorectal cancer were identified by two reviewers. Data Extraction: The extraction of data and its evaluation is done in most of the process so paired. Limitations: Not strictly complies with the methodology of a systematic review and therefore reproducibility is questionable, the conclusions of this study should be extrapolated with caution. Conclusions: The major strategy of screening on the effectiveness of early detection of premalignant lesions or cancer is colonoscopy every 5 years, however it is necessary to evaluate this measure cost-effectiveness studies. For primary prevention, aspirin and cyclooxygenase-2 inhibitors reduce the incidence of colorectal adenomas. Aspirin can reduce colorectal cancer incidence. However, these medications may be associated with a significant risk of cardiovascular events and gastrointestinal bleeding. The balance between risks and benefits must be evaluated in future studies.

Hacia una visión dinámica de la ‘legalización’ de la política internacional: revisión crítica de la bibliografía

El concepto de legalización fue desarrollado recientemente por el neoliberalismo institucional como una forma especial de institucionalización de las relaciones internacionales. Los autores neoliberales caracterizan la legalización a partir de las categorías utilizadas por H. L. A. Hart para distinguir el derecho de otros mecanismos de control social, como el poder y la moral. En Hart, estas categorías responden a una finalidad normativa: reconstruir teóricamente el derecho como un sistema independiente de la voluntad y de las convicciones de quienes lo interpretan y aplican. Sin embargo, esta separación entre lenguaje y práctica jurídica desconoce importantes contribuciones de la tradición analítica en filosofía del lenguaje, en cuanto a la relación entre lenguaje y realidad. En particular, termina reduciendo el derecho a simples formas y textos vacíos, y con ello desconoce que a través de las prácticas jurídicas se va dando significado a los textos normativos.Adoptar esta visión del derecho al estudio de las relaciones internacionales tiene, al menos, una consecuencia metodológica: el simple análisis formal del texto de los tratados no permite comprender el efecto del derecho internacional en el comportamiento de los Estados. Para entender las relaciones entre el derecho internacional y el comportamiento estatal es necesario describir la manera como se construye el significado de los textos a través de la práctica jurídica de los Estados. En tal sentido, resultaría útil redefinir la agenda de investigación neoliberal en relación con la legalización y enfocarse en la forma como los Estados y los tribunales internacionales construyen el significado de los tratados y demás normas internacionales.-----The concept of legalization was recently developed by neoliberal institutionalism as a special kind of institutionalization of international politics. Neoliberals built the concept of legalization using the analytical tools developed by H. L. A. Hart to distinguish law from other mechanisms of social control, like power and morals. Within Hart’s theory, such tools have a normative function: theoretically rebuilding law as a system of rules that is independent from the will and the beliefs of those who interpret and apply legal rules. However, Hart’s resulting separation of legal texts from legal practice obscures important contributions that the analytical tradition in philosophy of language has made to the understanding of the relation between language and reality. Specifically, such a separation reduces law to simple forms and texts disregarding the extent to which legal practice gives meaning to legal texts.Adapting Hart’s conception of law to International Relations has at least one important methodological consequence: the formal analysis of treaties cannot explain the influence of international law over state behavior. To understand the influence of international law on state behavior, one must previously describe the relation between legal practice and the meaning of legal texts. Thus, a redefinition of neoliberal research agenda on legalization should focus on the way States and international courts construct the meaning of treaties and other international norms.

Can SMS Technology Improve Low Take-up of Social Benefits?

Low take up of stigma-free social benefits is often blamed on information asymmetries or administrative barriers. There is limited evidence on which of these potential channels is more salient in which contexts. We designed and implemented a randomized controlled trial to assess the extent to which informational barriers are responsible for the prevalent low take-up of government benefits among Colombian conflict-driven internal refugees. We provide timely information on benefits eligibility via SMS to a random half of the displaced household that migrated to Bogot´a over a 6-month period. We show that improving information increases benefits’ take up. However, the effect is small and only true for certain type of benefits. Hence, consistent with previous experimental literature, the availability of timely information explains only part of the low-take up rates and the role of administrative barriers and bureaucratic processes should be tackled to increase the well-being of internal refugees in Colombia.
