This research investigated how teachers express links between ideas in speech, gestures, and other modalities in middle school mathematics instruction. We videotaped 18 lessons (3 from each of 6 teachers), and within each, we identified linking episodes—segments of discourse in which the teacher connected mathematical ideas. For each link, we identified the modalities teachers used to express linked ideas and coded whether the content was new or review. Teachers communicated most links multimodally, typically using speech and gestures. Teachers’ gestures included depictive gestures that simulated actions and perceptual states, and pointing gestures that grounded utterances in the physical environment. Compared to links about new material, teachers were less likely to express links about review material multimodally, especially when that material had been mentioned previously. Moreover, teachers gestured at a higher rate in links about new material. Gestures are an integral part of teachers’ communication during mathematics instruction.

The community college mission has been the subject of considerable review and commentary since its conception. Based on traditional concerns of access, a consensus has largely been reached regarding the inclusion of transfer, career, developmental, and community foci within a comprehensive community college. While concerns regarding access and affordability have largely driven mission, community colleges have also begun to reach out to other groups of students, including international students and honors students, raising questions about mission. Community colleges have addressed this latter group through honors sections and programs. As with four-year colleges, community colleges have also begun to institute honors colleges as a way to recruit and serve high achieving students who might otherwise go elsewhere. Based on a case study of one college's efforts to establish an honors college, we suggest a contingent model for development of honors colleges at the community college. The ultimate determinations as to whether the honors college is true to the community college mission lies in the composition of honors college participants. Districts that can use honors colleges to attract diversity in terms of underrepresented groups to their colleges may fulfill the promise of the traditional community college mission by making the transition from the community college to a selective four-year institution less onerous. The enhanced confidence, success, and social capital obtained in such an honors college simultaneously meets the egalitarian and meritocratic aims of the community college.

This study aimed at detecting the prevalence of antibiotic-resistant serotypes of Escherichia coli in Cochin estuary, India. E. coli strains were isolated during the period January 2010–December 2011 from five different stations set at Cochin estuary. Water samples from five different stations in Cochin estuary were collected on a monthly basis for a period of two years. Isolates were serotyped, antibiogram-phenotyped for twelve antimicrobial agents, and genotyped by polymerase chain reaction for uid gene that codes for β-D-glucuronidase. These E. coli strains from Cochin estuary were tested against twelve antibiotics to determine the prevalence of multiple antibiotic resistance among them. The results revealed that more than 53.33% of the isolates were multiple antibiotic resistant. Thirteen isolates showed resistance to sulphonamides and two of them contained the sul 1 gene. Class 1 integrons were detected in two E. coli strains which were resistant to more than seven antibiotics. In the present study, O serotyping, antibiotic sensitivity, and polymerase chain reaction were employed with the purpose of establishing the present distribution of multiple antibiotic-resistant serotypes, associated with E. coli isolated from different parts of Cochin estuary.

The University of Illinois inertial electrostatic confinement (IEC) device provides 10/sup 7/ 2.5 MeV D-D neutrons/second when operated with a steady-state deuterium discharge at 70 kV. Being compact and lightweight, the IEC potentially represents an attractive portable neutron source for activation analysis applications. The plasma discharge in the IEC is unique, using a spherical grid in a spherical vacuum vessel with the discharge formed between the grid and the vessel wall, while the -70 kV grid (cathode) also serves to extract high-energy ions. Two key features of the IEC discharge are discussed: 1) the breakdown voltage characteristics as a function of pressure-grid/wall distance (pd), and 2) the formation of ion microchannels that carry the main ion flow through grid openings.

Cervical spine trauma can clearly result in neurologic injury. An unusual traumatic event is a vascular insult of the vertebral arteries, potentially leading to stroke. The vertebral arteries are vulnerable to compression at several sites in the cervical spine. The high degree of physiologic rotation at the atlanto-axial joint places the vertebral artery at risk through normal daily activities as well as following forceful trauma, including manipulative treatment. Cerebrovascular insufficiency is an uncommon but serious complication of cervical spinal manipulation, which can lead to posterior circulatory impairment. Comprehensive diagnostic studies may be required to differentiate primary intracranial pathology from cerebral symptoms secondary to vascular compromise.

Transient acantholytic dermatosis is a self-limiting benign disease. It is characterized by multiple pruritic erythematous papules and papulovesicles found predominantly on the trunk and extremities. This primary acantholytic dermatosis affects individuals older than 40 years.

This paper, which was presented at the Institute Conference on navigation equipment and training standards held in Cardiff on 2–3 April, reviews the recent creation of international safety standards for shipborne electronic navigational aids and the new institutional framework in which these are being generated at IMO, IEC and ISO. It suggests that these safety standards, where they exist, are very similar to those needed by shipowners for efficiency of shipoperation.The paper which follows, by Moore and Page, was also presented at the Conference, an account of which appears in the Record.
