Bilingual Education in the USA: A Transition to Monolingualism?

Although bilingual education has never enjoyed widespread support in the USA, several models can be distinguished for language minority students: transitional bilingual education, dual language (or two-way immersion) programs, and speech community models. In this literature review, these models are examined to determine which is the most effective.

Regulating Casino Gaming: A Checklist for States Considering It

In his essay - Regulating Casino Gaming: A Checklist for States Considering It – by Leonard E. Goodall, Professor of Management and Public Administration, College of Business and Econornics, University of Nevada, Las Vegas, Professor Goodall initially states: “Since various states are likely to continue to debate the issue of the establishment of legal casinos, and since states considering legal casinos must also decide how best to regulate them, the author discusses the similarities and contrasts in the regulatory systems already in operation.” Certainly not all states have solicited casino gaming, or what people generally refer to as gambling, but many have and the list is growing. If casinos are to be, and indications are that many more states will endorse gaming as a source of revenue, then regulating them must follow as a matter of due course says the author. Keep in mind this essay was written in 1988, and the actuality of casino gaming has indeed come to fruition in many states. “Nevada, having legalized casino gaming in 1931, has over a half-century of experience with the regulatory process,” Professor Goodall informs. “When New Jersey approved the establishment of casinos in Atlantic City in 1976, state officials studied the Nevada system carefully and adopted many of Nevada's procedures.” Professor Goodall bullet-points at least 7 key elements that states wanting to pursue gaming should, or in the cases of Nevada and New Jersey, have already addressed in regard to regulation of the industry. Goodall parses, in more detail, those essentials. The ultimate form of regulation is ownership Goodall says. Either state run, or private are the logical options. “The arguments for private ownership have been both pragmatic and political,” Goodall says. “Legislators, like the general public, are skeptical of the ability of state bureaucracies to run big businesses in an efficient manner. Many of them also believe regulation can be more effective if there is at least an arm's-length distance between regulation and ownership,” the professor opines. Additionally important to consider is the purpose of legalization, says Goodall. Are the proceeds earmarked for general funds, or to be used specifically? Geographic considerations are key, Goodall points out. “This decision will depend partly on a state's reasons for having casinos in the first place,” he expands. “New Jersey's policy, for example, is obviously consistent with its goal of using casinos to reinvigorate Atlantic City.” “In both states, one of the most important functions of the regulatory agencies is that of licensing, the process of investigating individuals or organizations and then authorizing them to participate in the gaming business,” Goodall provides. In closing, Goodall says there is no need for ensuing states to reinvent the wheel when it comes to casino gaming regulation. Nevada and New Jersey already provide two good designs from which to emulate and/or build upon.

In Vivo Characterization of Myocardial Tissue Post Myocardial Infarction Using Combined Fluorescence and Diffuse Reflectance Spectroscopy

Accurately assessing the extent of myocardial tissue injury induced by Myocardial infarction (MI) is critical to the planning and optimization of MI patient management. With this in mind, this study investigated the feasibility of using combined fluorescence and diffuse reflectance spectroscopy to characterize a myocardial infarct at the different stages of its development. An animal study was conducted using twenty male Sprague-Dawley rats with MI. In vivo fluorescence spectra at 337 nm excitation and diffuse reflectance between 400 nm and 900 nm were measured from the heart using a portable fiber-optic spectroscopic system. Spectral acquisition was performed on - (1) the normal heart region; (2) the region immediately surrounding the infarct; and (3) the infarcted region - one, two, three and four weeks into MI development. The spectral data were divided into six subgroups according to the histopathological features associated with various degrees / severities of myocardial tissue injury as well as various stages of myocardial tissue remodeling, post infarction. Various data processing and analysis techniques were employed to recognize the representative spectral features corresponding to various histopathological features associated with myocardial infarction. The identified spectral features were utilized in discriminant analysis to further evaluate their effectiveness in classifying tissue injuries induced by MI. In this study, it was observed that MI induced significant alterations (p < 0.05) in the diffuse reflectance spectra, especially between 450 nm and 600 nm, from myocardial tissue within the infarcted and surrounding regions. In addition, MI induced a significant elevation in fluorescence intensities at 400 and 460 nm from the myocardial tissue from the same regions. The extent of these spectral alterations was related to the duration of the infarction. Using the spectral features identified, an effective tissue injury classification algorithm was developed which produced a satisfactory overall classification result (87.8%). The findings of this research support the concept that optical spectroscopy represents a useful tool to non-invasively determine the in vivo pathophysiological features of a myocardial infarct and its surrounding tissue, thereby providing valuable real-time feedback to surgeons during various surgical interventions for MI.
