The Students\u27 View of the Functions of Mother Tongue in General English Program of ABC Course

This study aimed to find out the students ‘opinions on the use of mother tongue and its functions in Indonesian EFL classrooms. The data were the interviews with a total six students from level 1, 2 and 3 comprising one high achiever student and one low achiever student from each level. The findings show that all of the students agree that Indonesian can be occasionally used in the classroom by both teacher and students for a number of reasons: for the teacher to explain new and difficult vocabularies, explain grammar rules, organize tasks, maintain discipline, gain contact with individual students, for the students to ask and answer questions, communicate and discuss with classmates and for translating activities. The findings also show that the low proficiency students prefer to use Indonesian more than the higher proficiency students because of lack of vocabular

Writing across curriculum: Evaluating a faculty-centered approach

This paper discusses research on a pilot study for implementing a Writing Across the Curriculum (WAC) program in the College of Business (CoB) at a California Public University. Data analysis focused on faculty and writing assistant satisfaction using interviews, and on student learning as measured by evaluation of progressive writing assignments. Discussion includes: 1) assumptions on which the pilot was based and its goals, 2) overview of how the program was structured and implemented, 3) outcomes of the pilot program, and 4) recommendations for future programs. Results suggest both faculty and student participants were satisfied with the pilot program implementation and student writing improvement

How Positive Psychology Overlaps with a Culturally-Based Indigenous Addictions Treatment Program

Indigenous cultural teachings on well-being continue to be passed on from generation to generation. Research is showing promise in the effectiveness of participating in cultural practices as more First Nations are returning to their culture for healing and recovery in addictions treatment centres. Positive psychology may help explain why. A very brief and general background will be provided on some cultural well-being teachings and on the impacts of history that have had devastating effects on many Indigenous people. Even through historical challenges that affect present day life, more Indigenous people are returning to their cultural ways of healing and living well. This paper will look at positive psychology constructs and theories in the context of supporting the effectiveness of a culturally-based addictions treatment center program and at ways positive psychology can enhance the program

The syntheses of novel indicators and materials for chiral separation

The colorimetric properties of resorcinarene solutions had not been fully investigated since von Baeyer\u27s initial synthesis. We find that the solutions containing resorcinarene macrocycles develop color upon heating or standing. In the presence of saccharides, these solutions exhibit significant color changes which are readily observable by visual inspection. We determined that the solution color is due to macrocycle ring opening and oxidation. The optical responses to saccharides are due to complexation of the sugar with the acyclic chromophores. We have applied these mechanistic insights towards the challenging problems of the visual detection of saccharides and other important biologically analytes. In addition, we also report the first single crystal X-ray crystal structure determination of a rarely observed diamond resorcinarene stereoisomer. The visual sensing of saccharides is of importance to medical diagnostics and industry. The synthesis of the diamine tripod and the diamine fluorescein compounds will be presented and their application towards the detection of saccharides and biomolecules of interest will be discussed. In addition to this, the synthesis of a new cationic chiral surfactant, the l-arginine methyl ester, for use in chiral separations will also be presented

The population dynamics and recruitment pattern of the phoronid, Phoronopsis viridis

A dominant organism on intertidal Pacific Coast sandflats is the lophophorate Phoronopsis viridis Hilton. This suspension feeder builds a stiff, sandy tube, 3 mm wide and up to 20 cm long and usually lying within 6 cm of the surface (Johnson 1967a). Phoronopsis viridis is found over large areas and tidal ranges of sandflats in aggregate densities of over 21,000 phoronids per m2 (Ronan 1978). On Lawson\u27s Flat, the location of the present study, the areas of highest density of P. viridis have been known to persist for over 20 years (Steven Obrebski, personal communication). The factors accounting for the persistence of these dense phoronid populations have not been studied although four hypotheses have been proposed (see Ronan 1975, 1978). These are: 1) dense clusters of adult phoronids increase the probability of successful gamete fertilization; 2) high densities of phoronids stablize the sediment, thus limiting the movement of large burrowing in fauna that are potentially destructive to phoronids (Ronan 1975); 3) a dense canopy of lophophores slows currents over the sediment surface, increasing the deposition of food items; and 4) clustering limits the effects of predation. The sudden retraction of a lophophore in response to a disturbance results in withdrawal of neighboring phoronids in the area of the disturbance (Ronan 1978). In order to evaluate the adaptive significance of population persistence it is crucial to understand the mechanism by which dense populations :persist. Therefore the purpose of this study is not to assess the adaptive significance of clustering, but rather to determine what mechanisms might explain the persistence of dense phoronid populations.. Consequently, this study is more applicable to an ecological time scale than an *evolutionary one. In this study the population dynamics and recruitment pattern of P. viridis is described with reference to the mechanism which enables persistence of dense phoronid areas. In addition, the effects of food abundance and the reworking activity of the surface deposit feeder, Axiothella rubrocincta Johnson, a maldanid polychaete, on P. viridis density and recruitment are measured

Searching the best approach for third-generation cholecystectomy

[Excerpt] We carefully read the study from Pai el al1 that demonstrates the technical feasibility of transcolonic cholecystectomy. Recently, we also investigated an endoscopic approach to perform scarless cholecystectomy through a transgastric and transvesical combined approach.[2] In our study, we also confirmed that an abdominal inferior port provides an en face orientation to the upper abdominal organs and allows better visualization and the ability to work straightforwardly. However, for these purposes, we used a transvesical instead of a transcolonic port. In fact, the transvesical access to the peritoneal cavity was feasible, easy to install, and safe in a survival porcine model study. Moreover, it should be emphasized that we did not experience any complications, such as adhesions or peritonitis, even when we left the vesicotomy point unclosed.[3] However, previous studies that tried to perform cholecystectomy by natural orifice transluminal endoscopic surgery (NOTES) performed it by using a single port, either transgastric or transcolonic.[1,4,5] These approaches share common limitations, such as difficulties in performing effective retraction and dissection with triangulation. In fact, we should not forget that cholecystectomy is a moderately complex procedure, usually needing 4 to 5 trocars in the laparoscopic technique. To deal with these limitations, we combined 2 diametrically opposed ports (transgastric and transvesical), which was particularly useful.[2] [...](undefined
