This is a work of an exploratory and qualitative nature, which mainly collected the information through primary sources. That is, through the testimonies of filmmakers and producers from different parts of Bolivia. The fundamental tool for data collection was the semi-structured interview, probably the most widely used methodology in qualitative research. It is concluded that, from the perspective of the filmmakers, the effects of the pandemic on Bolivian audiovisuals were aggravated by the political crisis and by poor management of the transitional government. On the other hand, the transformation processes of the modes of production, distribution and marketing, accelerated by the pandemic, must be assumed, rethought and assimilated from the Bolivian context, as for example, the use of VOD platforms. Finally, a trend was found in national filmmakers, they believe that Bolivian cinema must be committed to social reality and should dialogue with the other.","PeriodicalId":299795,"journal":{"name":"Informatica Didactica","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130776837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Index investing represents a passive investment strategy of holding hundreds of stocks instead of the active management approach used by these experts. After exposing said results, a theoretical framework will be presented that explains why money managers have such a difficult time outperforming their benchmark indexes. Later on, a back-test experiment will be presented and thoroughly explained showing five different hypothetical investment scenarios over several 20-year periods with the attempt to quantify the potential benefit of perfectly timing the market and compare it to the cost of waiting for a better time to invest. The results find shows that the cost of waiting is much greater that the potential benefit of perfectly timing the market and the best alternative would be to invest available cash immediately regardless of market or economic outlook.","PeriodicalId":299795,"journal":{"name":"Informatica Didactica","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123418991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It questions the Canadian census ́ official position regarding the “considerable” central re-densification movement in downtown Montreal. A methodology supported by opinion surveys presents as objective the design of a regression model conceived through a SPSS process that discloses the interrelation that a “free-will-to-stay” in that downtown (Sainte-Marie neighbourhood), keeps to a set of the most representative variables of residential improvement in housing/services from the needs/impedances (difficulties to achieve it) perspective. The idea here is to estimate the central attraction power, within the limitations of a pilot-project. The “monthly-income”, ‘ownership”, “impedance-toresidential-improvement”, “need-for-health-services-improvement”, “impedance-to-health-services-improvement”, and “impedance-to-transportation-improvement” independent variables were the most explanatories of the “free-will-tostay” dependent variable’s behaviour.

In relation to the characteristics of human resources, the results reveal that the presence of qualified human resources in a company has a positive impact on the results of innovation and on labor productivity. Otherwise, it is established that the presence of unskilled human resources causes an inverse effect on labor productivity. Regarding to the characteristics of the companies, it is possible to establish that the presence of foreign capital and the exports positively affect investments in innovation.

The paper examines architectural references from other revolutions, reviews the evolutionary characteristics of the “Process of Change”, observes the conditions of the Bolivian urban scenario, analyzes a series of architectural facts using the trilogical approach and finally characterizes the main state buildings according to codes and features that would coincide with the revolutionary discourse and the new paradigm of “living well”. The final review and reflection corroborates a limited coincidence of architectural practice with revolutionary discourse and seems to ratify the notion that revolutionary architecture is more of a market product.","PeriodicalId":299795,"journal":{"name":"Informatica Didactica","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115589372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hallazgos para destacar en este proceso son, primero, la relevancia de los estudios epidemiologicos sobre alcoholismo para entender las adicciones y, posteriormente, la salud mental en general. Segundo, la incorporacion de especialistas de las ciencias sociales (psicologas, trabajadoras sociales y sociologos) a las instituciones de atencion e investigacion en salud mental.

No se incluye el abordaje de la estructura social desde la teoria marxista en este ensayo, dado que ello implicaria una revision teorica exhaustiva que excede su objetivo.  Se exponen algunas ventajas de la nocion de “redes sociales” para el estudio de la estructura social en forma complementaria al uso de las tecnicas atributivas clasicas de la sociologia empirica moderna. Para este desafio se proponen indicadores, metricas, modelos de redes aleatorias y topologias ARS. Se considera que el abordaje empirico y el teorico permiten un corpus integrado para la conceptualizacion y la investigacion de la estructura social. La aplicacion del network thinking para examinar la estructura social resulta en cierta forma original, pues es un enfoque que se ha utilizado mas frecuentemente para analizar la dinamica de ciertos agentes o grupos dentro de la sociedad. Se concluye que la confluencia del ARS con algunas nociones teoricas de la teoria de sistemas sociales es util para el analisis de la estructura social, conceptualizada como patrones dinamicos de intercambios reales y potenciales entre individuos humanos en formato de redes.","PeriodicalId":299795,"journal":{"name":"Informatica Didactica","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128511967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
