Appreciation of humor sense in college students

Appreciation of humor includes several cognitive and social processes. None can say that two communities will laugh at the same jokes and find funny the same humorous content. This study worked differences in humor appreciation of university students and comparisons were made between sex and age of participants. To assess the appreciation of humor was built an instrument with 15 written jokes. This instrument was presented to a total sample of 81 students, divided into 3 groups of different age. Participants had to evaluate two aspects: the playfulness and the difficulty of each stimulus or humorous vignette. The jokes that showed significant differences in jocularity have a particular structure marked for a disqualifying content to men, indicating, as noted the literature, that men have more fun with sexual humor and prefers this kind of jokes as well as content related to aggressive or hostile, while women have more fun with humorous vignettes when the man is the victim and reject more when the victim is a woman. In terms of age and the appreciation of humor, there are differences in the type of situations and social contexts valued in the jokes, involving relationship between situational and social aspects of humor.

Alcohol consumption in young college students

Descriptive Cross-sectional study involving 787 students from a private university in Bogota. Its objectives were to determine the alcohol consump- tion prevalence, alcoholism and risk of alcoholism and determine the current pattern of alcohol con- sumption. A survey –which included the CAgE index– was used to collect the data. A prevalence of alcoholism of 23%, and of risk of alcoholism of 15% were found. Results show that alcohol con- sumption in university students begins in high school and it is a problematic conduct that it is worth being enlarged and analyzed in greater detail including other variables and perfecting the diag- nosis of alcoholism and its risk in order to achieve early identification and intervention.

Predictors of Attitudes toward Cosmetic Surgery among U.S. and Colombian College Women: The Roles of Eating Behaviors and Demographic Variables

Cross-cultural studies on eating behaviors and related constructs can identify cultural and social factors that contribute to eating disorder symptomatology. Eating disorders (EDs) are a major cause for concern in the U.S., and recent studies in Colombia have shown growing rates among their female population. In addition, cosmetic surgery procedures have been increasing rapidly in both the U.S. and Colombia, and preliminary research suggests a positive relation between disordered eating and endorsement of plastic surgery. In samples of college women from Colombia and the U.S., we investigated patterns of association between disordered eating variables and cosmetic surgery acceptance. Our approach utilized separate analyses for various subcomponents of disordered eating (to determine their unique associations with cosmetic surgery acceptance) while adjusting for potentially relevant covariates and examining cross-cultural patterns. Participants were students at an urban, public college in the U.S. (n=163) and an urban, private college in Colombia (n=179). Overall, our findings suggested that participants from Colombia with greater disordered eating were more likely to endorse cosmetic surgery for social reasons, while those from the U.S. were more likely to consider undergoing cosmetic surgery for personal reasons. Differing findings between the two samples may be due to cultural and social factors, which we delineate. These findings also have potential implications for presurgical counseling of cosmetic surgery candidates.

Remesas y desarrollo económico. Un análisis empírico del caso mexicano

El objetivo de este trabajo es contribuir a identificar el efecto de las remesas que envían los emigrantes a sus comunidades de origen en México. Del mismo modo, se estudia el efecto que la participación de la mujer tiene en este proceso. La fuente de información es el Consejo Nacional de Población de México CONAPO y contiene variables a nivel estatal y municipal para el año 2000. La base de datos contiene índices de desarrollo humano, intensidad migratoria y remesas para los 2443 municipios mexicanos. La evidencia empírica sugiere que las remesas tienen un impacto positivo sobre los niveles de desarrollo de las comunidades receptoras. No obstante, la relación entre remesas y desarrollo es no lineal. Adicionalmente, se en contró que el efecto positivo que tienen las remesas sobre el desarrollo es más alto cuando la cabeza de familia de los hogares receptores es mujer.

Energy saving innovations, non-exhaustible sources of energy and long-run: what would happen if we run out of oil?

We formulate and solve a model of factor saving technological improvement considering three factors of production: labor, capital and energy. The productive activities have three main characteristics: first, in order to use capital goods firms need energy; second, there are two sources of energy: non-exhaustible and exhaustible; third, capital goods can be of different qualities and the quality of these goods can be changed along two dimensions -reducing the need of energy or changing the source of energy used in the production process. The economy goes through three stages of development after industrialization. In the first, firms make use of exhaustible energy and the e¢ ciency in the use of energy is constant. In the second stage, as the price of energy grows the e¢ ciency in its use is increased. In the third stage, the price of exhaustible sources is so high that firms have incentives to use non-exhaustible sources of energy. During this stage the price of energy is constant. In this set up, the end of the oil age has level effects on consumption and output but it does not cause the collapse of the economic system.

Factor saving innovations and factor income shares

We present an endogenous growth model where innovations are factor saving. Technologies can be changed paying a cost and technological change takes place only if the benefits are larger than the costs. Since the gains derived from factor saving innovations depend on factor abundance, biased innovations respond to changes in factors supply. Therefore, as an economy becomes more capital abundant agents try to use capital more intensively. Consequently, (a) the elasticity of output with respect to reproducible factors depends on the capital abundance of the economy and (b) the income share of reproducible factors increases as the economy grows. Another insight of the model is that in some economies the production function converges to an AK in the long run, while in others long-run growth is zero

Energy Saving Innovations, Non-Exhaustible Sources of Energy and Long-Run: What Would Happen if we Run Out of Oil?

Se formula y resuelve un modelo de cambio tecnológico ahorrador de factores de producción que considera tres factores: capital, trabajo y energía. El modelo cuenta con características específicas con respecto a la interacción n entre la energía (la cual, de acuerdo a su fuente puede ser renovable y no renovable) y el capital. Una vez esta economía se ha definido, se supone que evoluciona en tres etapas luego de su industrialización, durante las cuales el carácter renovable o no renovable de la energía influye su precio relativo, eficiencia y afecta también el nivel agregado de consumo y producción de la economía, sin que esta evolución lleve al colapso del sistema económico.
