Marijuana Legislation: Identifying the Impact on the Oral Healthcare Provider

Objectives/Aims: Since the mid-2000s, the United States has seen a surge in legislation involving the legalization of marijuana, both recreationally and medicinally. The relaxed laws translated into an increase of marijuana consumption and thereby a potential increase in the number of patients a provider will see that are cannabis users. The purpose of this review is to illustrate how the providers begin to see pathologies related to cannabis use more frequently, and how they will need to be prepared for ways this can be addressed. Additionally, oral healthcare providers will face ethical dilemmas and legal challenges when treating patients and their ability to give informed consent. Methods: Research reviewed in this paper was compiled from scholarly articles and peer-reviewed journals, including PubMed and CINAHL, published within the last five years. Studies were analyzed on the impact legalization and decriminalization laws have had on marijuana use. Additional research reviewed numerous pathologies related to marijuana use in the dental cavity. Results: Based on current proposals, it is expected that 40 states will legalize marijuana by the end of 2020. Studies conducted in states such as Oregon, Colorado and Alaska have shown an increase in marijuana usage since legalization has occurred. Research reviewed showed multiple conditions related to marijuana use. Periodontitis, xerostomia, oral cancer, and staining are several of the associated pathologies. Conclusion: Research suggests an anticipated increase of marijuana users in states that will soon pass legalization. Studies have also shown that there is a higher prevalence of pathologies of the oral cavity in cannabis users versus non cannabis users. The oral healthcare provider will treat more pathologies related to cannabis use and deal with the legal challenges presented to them surrounding informed consent.https://scholarscompass.vcu.edu/denh_student/1016/thumbnail.jp

Relationships Among Teachers\u27 Efficacy, Teachers\u27 Locus-of-control, and Student Achievement

The purpose of this study was to determine if teacher effectiveness, as measured by value-added gain scores on student achievement, was related to the teacher personality characteristics of efficacy and locus of control. The value-added mean gain scores for each teacher were correlated with teachers\u27 scores on the Rand Corporation Efficacy Scale and the Rose and Medway Teacher Locus of Control Scale. A multiple regression analysis was used to determine if these teacher characteristics along with selected demographic variables could be used as good predictors of achievement gain. The population consisted of 132 middle school teachers across five subject areas in one county in Northeast Tennessee. No correlation was found between either teacher efficacy or locus of control and mean gain scores. A statistically significant relationship was revealed between gender and teacher efficacy with females indicating higher scores than males. Pairwise correlational analysis also revealed that mathematics gain scores were significantly correlated with age, college major, experience, and certification. Multiple regression analysis was used to determine the extent to which the demographic variables and the personality variables were related to student achievement. The percent of variance in mathematics scores attributed to teacher age and major indicated that these two variables were good predictors of value-added gains. Neither the demographic nor the study variables entered into the regression formula for the other academic subjects studied

The History, Present Condition, and Future of the Molluscan Fisheries of North and Central America and Europe: Volume 2, Pacific Coast and Supplemental Topics

Over 100 molluscan species are landed in Mexico. About 30% are harvested on the Pacific coast and 70% on the Atlantic coast. Clams, scallops, and squid predominate on the Pacific coast (abalone, limpets, and mussels are landed there exclusively). Conchs and oysters predominate on the Atlantic coast. In 1988, some 95,000 metric tons (t) of mollusks were landed, with a value of $33 million. Mollusks were used extensively in prehispanic Mexico as food, tools, and jewelry. Their use as food and jewelry continues. Except in the States of Baja California and Baja California Sur, where abalone, clams, and scallops provide fishermen with year-round employment, mollusk fishing is done part time. On both the Pacific and Atlantic coasts, many fishermen are nomads, harvesting mollusks wherever they find abundant stocks. Upon finding such beds, they build camps, begin harvesting, and continue until the mollusks become so scarce that it no longer pays to continue. They then look for productive beds in other areas and rebuild their camps. Fishermen harvest abalones, mussels, scallops, and clams by free-diving and using scuba and hooka. Landings of clams and cockles have been growing, and 22,000 t were landed in 1988. Fishermen harvest intertidal clams by hand at wading depths, finding them with their feet. In waters up to 5 m, they harvest them by free-diving. In deeper water, they use scuba and hooka. Many species of gastropods have commercial importance on both coasts. All species with a large detachable muscle are sold as scallops. On the Pacific coast, hatchery culture of oysters prevails. Oyster culture in Atlantic coast lagoons began in the 1950's, when beds were enhanced by spreading shells as cultch for spat. (PDF file contains 228 pages.

The History, Present Condition, and Future of the Molluscan Fisheries of North and Central American and Europe: Volume 1, Atlantic and Gulf Coasts

This three-volume monograph represents the first major attempt in over a century to provide, on regional bases, broad surveys of the history, present condition, and future of the important shellfisheries of North and Central America and Europe. It was about 100 years ago that Ernest Ingersoll wrote extensively about several molluscan fisheries of North America (1881, 1887) and about 100 years ago that Bashford Dean wrote comprehensively about methods of oyster culture in Europe (1893). Since those were published, several reports, books, and pamphlets have been written about the biology and management of individual species or groups ofclosely related mollusk species (Galtsoff, 1964; Korringa, 1976 a, b, c; Lutz, 1980; Manzi and Castagna, 1989; Shumway, 1991). However, nothing has been written during the past century that is comparable to the approach used by Ingersoll in describing the molluscan fisheries as they existed in his day in North America or, for that matter, in Europe.
