Nonlesions, misdiagnoses, missed diagnoses, and other interpretive challenges in fish histopathology studies: a guide for investigators, authors, reviewers, and readers.

Differentiating salient histopathologic changes from normal anatomic features or tissue artifacts can be decidedly challenging, especially for the novice fish pathologist. As a consequence, findings of questionable accuracy may be reported inadvertently, and the potential negative impacts of publishing inaccurate histopathologic interpretations are not always fully appreciated. The objectives of this article are to illustrate a number of specific morphologic findings in commonly examined fish tissues (e.g., gills, liver, kidney, and gonads) that are frequently either misdiagnosed or underdiagnosed, and to address related issues involving the interpretation of histopathologic data. To enhance the utility of this article as a guide, photomicrographs of normal and abnormal specimens are presented. General recommendations for generating and publishing results from histopathology studies are additionally provided. It is hoped that the furnished information will be a useful resource for manuscript generation, by helping authors, reviewers, and readers to critically assess fish histopathologic data.

The Feasibility of Cuban Market Economy: A Comparison with Vietnam

In spite of the difficulties incurred by its people, Cuba has maintained a centrally planned economy with single party system. On the contrary, Vietnam has introduced a market economy under communist rule, and succeeded in generally improving living standards. The factors that contributed to the introduction of Vietnamese-style reforms are (1) severe economic crisis, (2) demonstration effects from neighboring countries, (3) poor social policy, (4) initiatives by ex-conservative leader/s, and (5) weak state capacity. The conditions to sustain high economic growth are (1) social sectors familiar with capitalist economics, (2) abundant labor forces with relatively low labor cost, and (3) investment by exiles. This paper analyzes to what extent Cuba meets these conditions.

The Cuban Economy: A Current Evaluation and Proposals for Necessary Policy Changes

Politicians, social scientists and general readers have noted in both Cuban and international academic forums and periodicals that the well-being enjoyed by the Cuban people in the 1980s has been seriously compromised since the economic crisis of the 1990s. Even for the most skeptical of observers it is clear that this worsening of conditions can be attributed not only to external factors, such as the breakup of the international socialist system, the tightening of the US blockade, and the worldwide economic crisis suffered by underdeveloped countries, but also to internal factors that have kept the country from taking full advantage of the human and material potential available on the island. Although Cuba is currently experiencing an economic recovery from the collapse in GDP in the mid 1990s following the collapse of its ties with the Socialist Bloc, it continues to maintain high import coefficients due to longstanding structural.
