Trading Volumes in Dynamically Efficient Markets

The classic Lucas asset pricing model with complete markets stresses aggregate risk and, hence, fails to investigate the impact of agents heterogeneity on the dynamics of the equilibrium quantities and measures of trading volume. In this paper, we investigate under what conditions non-informational heterogeneity, i.e. differences in preferences and endowments, leads to non trivial trading volume in equilibrium. Our main result comes in form of a non-informational no trade theorem which provides necessary and sufficient conditions for zero trading volume in a dynamically efficient, continuous time Lucas market model with multiple goods and securities.General Equilibrium, Trading Volume; heterogenous agents; multiple goods; incomplete markets; no-trade theorem.

Mycobacterium bovis infection in cattle in Morocco: preparation and evaluation of chemical extracts for use in detection of immune responses

Sodium deoxycholate (DOC) was utilized to extract immunologically-active cell wall components of virulent M. bovis and M. avium, isolated from cattle in Morocco and M. fortuitum as well as related organisms e.g., N. asteroides and R. equi. The extracts from M. bovis, N. asteroides, M. fortuitum, and M. avium, were fractionated by size exclusion chromatography using Sephadex S-200. Two fractions (1 and 2) were obtained at absorbance of 280 nm. Fraction 1 of M. bovis, M. avium, M. fortuitum and of N. asteroides and nonfractionated DOC extract of R. equi elicited delayed-type hypersensitivity responses in homologously or heterologously sensitized guinea-pigs. Significant enzyme-linked immunosorbent assay values were obtained using sera from cattle 4 weeks after sensitization with homologous bacterial preparations (p \u3c 0.01). Significant ELISA cross-reactions were observed in M. bovis or M. avium sensitized calves, using heterologous antigens;Mycobacteriologic examinations conducted on tissues collected from 246 cows in 5 major abattoirs of Morocco, revealed that M. bovis was isolated from 29.67% of the cattle examined. Mycobacteria other than M. bovis (MOTT) were isolated from tissues of 23 carcasses (9.34%). Three had lesions compatible with tuberculosis; M. bovis was not isolated;An indirect enzyme-linked immunosorbent assay using M. bovis PPD or M. bovis DOC fraction 1 as antigens was used for detecting antibodies in sera of cattle from which M. bovis was isolated. The sensitivity for M. bovis PPD was 76.71% and for DOC extract of M. bovis was 79.45%; the specificity was of 90% and 92%, respectively. These values are similar to those achieved by the tuberculin skin test (71);Investigations conducted on five selected herds in Morocco using the cervical intradermal tuberculin test and ELISA revealed that cattle in three herds were tuberculous. The comparative cervical tuberculin test using M. bovis and M. avium PPD\u27s at equal concentration was conducted within 24 hours of a positive or suspect skin response; no reactors were identified in the remaining two herds;Combination of ELISA and tuberculin skin test conducted on animals from tuberculous herds was found to be more sensitive than either test conducted alone

How do Advertising Imageries Contribute to Women\u27s Inequality for Profit in Tourism?

Objectives: This study analyzes the impact of the female body used for tourism marketing purposes on social norms, roles, and expectations. It also examines the importance of research in this field to shift marketing approaches contributing to gender stratification. This paper aims to research women’s body language, portrayal, beauty, and environment in tourism marketing imagery and their effect on gender inequalities. Then, the study introduces the social responsibility of media to promote inclusivity and diversity through their advertising methods. Moreover, this article considers the correlation between arousing emotions through displaying female bodies as advertising methods and consumer decision-making. This research is essential since it covers crucial topics shaping our world. Understanding their impacts on destinations’ populations and females, in general, is imperative to aspire to future societal improvements. Methods: This study uses an interpretivism approach to evaluate participants’ lived experiences through exploratory research that focuses on an inductive approach. This research used a phenomenology strategy and was conducted through a cross-sectional method. Data was collected through interviews, secondary data, and observational techniques. Data was collected through these methods to induct a theory and answer research questions. Interviews were unstructured and investigated participants’ lived experience and their feelings about this study. Results: Results are still pending. Conclusions: Many research studies specified the 1960s as the beginning of a new era, where visual marketing and gender stereotyping began. Most studies mentioned the lack of research regarding representation and gender stratification. Hence, it is clear that the emergence of marketing and advertising strengthened gender inequalities. Thus, research about tourism\u27s inclusivity methods and social responsibilities will benefit the industry and worldwide societies. Also, it is essential to develop policies that incite representing diverse types of local women in tourism advertising rather than using fantasy female bodies as marketing baits

Migrant Necropolitics at the Table: Civilized Cannibalism in Mahi Binebine\u27s \u3cem\u3eCannibales\u3c/em\u3e

In Cannibales, the Maghrebi Francophone author Mahi Binebine revisits the encounter between the so-called “cannibals” and the European colonizer in the context of illegal immigration where bodies become commodities exchangeable for social improvements creating a different form of cannibalism. It is no longer the usual dichotomy between the civilized and the savage that is at work but rather a “civilized” European imperialist who feeds himself on a migrant’s flesh. This article argues that this representation works as a “colonial fragment” from the past but contextualized in today’s globalization. Binebine’s morbid depiction of an ambivalent postcolonial cannibalistic encounter translates as a representation of migrants in terms of cannibalistic necropolitics. The illegal migrant has no choice but to be swallowed by a narcissistic exocannibalism which seeks to incorporate what it feeds on to a total unity suggesting a bleak future not only for illegal migrants but for globalization as possibly devouring itself
