On August 1, 1996, the speed limit on certain sections of Michigan freeways increased from 104.6 to 112.6 km/h (65 to 70 mph). This was due to the Michigan Legislature passing a bill that permitted the governor of Michigan to increase the speed limit given that a study be conducted to determine the effects on safety and capacity. Michigan State University conducted the study that determined the effects of increasing the speed limit on certain sections of highway. This study examined not only freeways that were increased to 112.6 km/h (70 mph), but also the speeds and capacities of freeway sections where the speed limit was not increased. Different types of speed analyses were done in comparing the test sections where the speed limits were raised with the control sections where the speed limits were not raised. The analysis also included categorizing the roadway into intercity and recreational routes to determine the effect on speeds for different uses in road use. The speed data also were broken down into different vehicle types. A preliminary accident analysis was performed on the control and test sections to determine the effect of increasing the speed limit on accidents. It was proved that increasing the speed limit on certain sections of freeway in Michigan had little effect on the change in speed and capacity on both test and control sections.

The most frequently asked questions regarding the phenomenon of American universities in the Arabian Gulf are: how good are they and how likely are they to endure? Already one of the first to enter the arena (George Mason University in 2005) was forced to close its Ras al-Khaimah campus in October of 2009 “after reaching an impasse with our partner over budget and control issues” (http://eagle.gmu.edu/newsrooms/740). GMU’s former students were directed to its American campus and seven other institutions within the UAE with whom GMU had teach-out agreements. One of these seven institutions has now closed as well: on 6 July 2010 Michigan State University (MSU) announced it was closing its undergraduate programs in Dubai. Its former students were offered a special package to attend the MSU campus in Lansing. As reported in the Lansing State Journal, the reason given was that the Dubai campus had “failed to attract sufficient numbers of students and was no longer financially sustainable.” It had just eighty-five students. However, MSU still had to pay between $1.3–1.7 million in “wind-down costs” (http://lansingstatejournal.com/article/20100706/NEWS01/307060031/MSU-to-close-programs-at-Dubai-campus).

A formative evaluation was conducted of the Chemical Health Education and Coaching (CHEC) program sponsored by the Youth Sports Institute at Michigan State University. The degree to which high school athletic coaches (a) became knowledgeable about chemical health and (b) were confident in their ability to apply that knowledge to their team were the two primary concerns of this study. Two hundred eighteen high school athletic coaches comprised the experimental and control groups to whom identical pretest and posttest instruments were administered. The CHEC program consisted of three 1-hr sessions. The subjects were asked to respond to one questionnaire that assessed both their knowledge and confidence in that knowledge and their ability to use it with their athletes. The results indicated that the coaches who were exposed to CHEC were more knowledgeable and more confident than control coaches.

The article is devoted to the topical problem of modern principles of developing tests of Russian as a foreign language (RFL), taking into account the world experience. The purpose of the article is to summarize the modern principles of language test development and to show how they are implemented in the new tests of Russian as a foreign language. The materials of the article include the research papers of Russian and foreign authors in the sphere of methodology over the past 20 years, as well as modern formats of testing in foreign languages. At the first stage of the study, general scientific methods of generalization, systematization and structuring were used. At the second phase, a new format of the RFL test Reading and Use of Language (B2) was modelled, combining language and communication competence testing. At the third stage, an experiment was conducted to test the new format. 48 foreign master students studying the program Russian Language and Russian Culture in the Aspect of Russian as a Foreign Language in Saint Petersburg State University took part in the experiment. It was concluded that the modern language test, in accordance with the basic cognitive and communicative principle of learning and control, should be based on the following principles: testing skills in different types of speech activities mainly on the text material; interdependence between the type of the task and the speech genre of the text being created/used in the task; basing on a linguistic and didactic description of the communicative competence level; integrative approach; using different types of test tasks within one subtest; the principle of increasing complexity of tasks; taking into account the complexity of each task in its assessment; task feasibility according to students educational level; taking into account the values of the multicultural world; taking into account international experience; basing on reliability and validity criteria of test tasks. These principles implemented in the new TORFL-II subtest format Reading and Use of Language are presented in the article. The implementation of modern test principles should ensure that all speech control facilities are systematically allocated to the appropriate level and parameters for their assessment. The above-mentioned principles of test creation and the example of their implementation can be taken as the basis of a full-fledged system of control and measurement materials based on linguistic and didactical descriptions of each level.

Abstract Since 2005, Michigan State University has offered an online graduate-level course in animal welfare assessment. The course was designed to overcome geographic barriers in terms of limited instructor expertise in welfare at individual universities and to reach an international student audience. Over 280 students have taken the course—including undergraduate, veterinary, and graduate students; practicing veterinarians; and professionals. Students have attended from 22 states and 13 different countries, including Thailand, Canada, Nepal, Kenya, China, and Australia. The course was designed and continues to be modified to accommodate students attending from different time zones, with different types of technology, and with different speeds and reliabilities of Internet access. An asynchronous format is used, with content delivered via short, recorded lectures and videos as well as electronically available textbook chapters and journal articles. In response to student and instructor needs, the course has evolved from a tech heavy but bandwidth intensive format to one using simpler technology and less bandwidth to reduce student barriers to participate and ensure equitable content access and engagement. Content is offered through the Desire 2 Learn course management system at MSU, which also performs accessibility checks of content. Lectures and videos are captioned to help accommodate visually impaired students or those in noisy environments and PDF handout versions of lecture slides are also made available. Rubrics and examples are used to guide completion of assignments. In 2020, the course was co-taught by MSU, Texas A&M and Virginia Tech. Several class meetings were held via Zoom to allow students to meet and interact with each other, though issues with scheduling prohibited all students from attending. Feedback surveys indicate students are generally satisfied with course content, delivery technology and interactions with instructors and peers. Creating an inclusive virtual environment requires attention to student constraints, with simpler typically being more accommodating.

Bovine respiratory diseases cause serious economic loses and present diagnostic difficulties due to the variety of etiologic agents, predisposing conditions, parasites, viruses, bacteria and mycoplasma, and may be multiple or complicated. Several agents which have been isolated from the abnormal lungs are still the subject of controversy and uncertainty. These include adenoviruses, rhinoviruses, syncytial viruses, herpesviruses, picornaviruses, mycoplasma, chlamydiae and Haemophilus somnus.Previously, we have studied four typical cases of bovine pneumonia obtained from the Michigan State University Veterinary Diagnostic Laboratory to elucidate this complex syndrome by electron microscopy. More recently, additional cases examined reveal electron opaque immune deposits which were demonstrable on the alveolar capillary walls, laminae of alveolar capillaries, subenthothelium and interstitium in four out of 10 cases. In other tissue collected, unlike other previous studies, bacterial organisms have been found in association with acute suppurative bronchopneumonia.

Dengue fever is a painful mosquito-borne infection caused by different types of virus in various localities of the world. There is no particular medicine or vaccine to treat person suffering from dengue fever. Dengue viruses are transmitted by the bite of female Aedes (Ae) mosquitoes. Dengue fever viruses are mainly transmitted by Aedes which can be active in tropical or subtropical climates. Aedes Aegypti is the key step to avoid infection transmission to save millions of people in all over the world. This paper provides a standard guideline in the planning of dengue prevention and control measures. At the same time gives the priorities including clinical management and hospitalized dengue patients have to address essentially.
