Integrative Learning Within Tutoring in Higher Education: Contexts for Connections

In response to a gap in the literature regarding integrative learning within higher education tutoring services and the discursive gap that limits how such tutoring is imagined, this multiple case study explored the ways integrative learning takes place within tutoring in higher education and the tools that enabled or constrained such learning. Six tutor-tutee pairs engaged in regular appointments for the topics of college algebra, psychology, finance, biology, theatre, and history, respectively. During the course of one academic semester, 12 participants took part in three interviews, and each pair was observed up to four times. Drawing from sociocultural activity theory, the transcripts were coded and analyzed to identify examples and mediational means of integrative learning in these cases. This analysis yielded a working definition in which integrative learning in tutoring in higher education takes place as learners create relevance from required coursework by articulating why the content has value, making connections, and exercising agency. Major tools affecting integrative learning in this study included dialogue, examples, and context. This study provided descriptive data and patterns that could contribute insights into integrative learning, expand the way tutoring is conceived in higher education, and offer models for tutor training and classroom instruction

Trilled song types are more salient than non-trilled song types in agonistic interactions between male song sparrows (Melospiza Melodia)

Most research on song complexity has mainly focused on repertoire size. However, the way various song structures within a repertoire function in male-male interactions is less well understood. In this study, I have explored the functional significance of songs containing a trilled syllable type shown to have a clear maximum physiological performance barrier versus songs that lack a trilled element. I performed playback experiments with 44 song sparrows on the campus of Western Carolina University in North Carolina. I found that males responded significantly more strongly to trilled than non-trilled songs, suggesting that song sparrows discriminate between song types within a repertoire. The results of this study suggest that male-male interactions may be important drivers for the evolution of complex repertoires in song sparrows. Future studies should focus on understanding how trilled and non-trilled songs function in male-male interactions

A Literary Reading Of Amos

The book of Amos has a unique form compared to other prophetic books in the Hebrew Bible. Its distinctive placement of the oracles against the nations (1:3-2:16). and vision sequences (7-9) make it difficult to read the text as a unified book. Yet, Amos employs the consistent rhetorical technique of “unmet expectations” that extends from the introduction (1:2), through the questions (3:2-8), to the visions (7-9). Furthermore, images of water, drought, and agriculture appear constantly within the text. Amos often utilizes these images when he employs his technique of unmet expectations, thereby creating a cohesive book. These images are rooted in the concrete social and political context of the eighth century’s sacred economy in which non-producing elites were often in conflict with subsistence-based agrarian communities

Genetic diversity and structure of Iberian Peninsula cowpeas compared to world-wide cowpea accessions using high density SNP markers

Cowpea (Vigna unguiculata L. Walp) is an important legume crop due to its high protein content, adaptation to heat and drought and capacity to fix nitrogen. Europe has a deficit of cowpea production. Knowledge of genetic diversity among cowpea landraces is important for the preservation of local varieties and is the basis to obtain improved varieties. The aims of this study were to explore diversity and the genetic structure of a set of Iberian Peninsula cowpea accessions in comparison to a worldwide collection and to infer possible dispersion routes of cultivated cowpea.This study was supported by EUROLEGUME project. This project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no 613781.

Global prevalence of childhood cataract: a systematic review

Childhood cataract is an avoidable cause of visual disability worldwide and is a priority for VISION 2020: The Right to Sight. There is a paucity of information about the burden of cataract in children and the aim of this review is to assess the global prevalence of childhood cataract. The methodology for the review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We performed a literature search for studies reporting estimates of prevalence or incidence of cataract among children (aged<18 years) at any global location using the Cochrane Library, Medline and Embase up to January 2015. No restrictions were imposed based on language or year of publication. Study quality was assessed using a critical appraisal tool designed for systematic reviews of prevalence. Twenty prevalence and four incidence studies of childhood cataract from five different geographical regions were included. The overall prevalence of childhood cataract and congenital cataract was in the range from 0.32 to 22.9/10000 children (median=1.03) and 0.63 to 9.74/10000 (median=1.71), respectively. The incidence ranged from 1.8 to 3.6/10000 per year. The prevalence of childhood cataract in low-income economies was found to be 0.42 to 2.05 compared with 0.63 to 13.6/10000 in high-income economies. There was no difference in the prevalence based on laterality or gender. This review highlights substantial gaps in the epidemiological knowledge of childhood cataract worldwide, particularly from low and lower middle-income economies. More studies are needed using standard definitions and case ascertainment methods with large enough sample sizes

Population‐based cohort study of outcomes following cholecystectomy for benign gallbladder diseases

Background The aim was to describe the management of benign gallbladder disease and identify characteristics associated with all‐cause 30‐day readmissions and complications in a prospective population‐based cohort. Methods Data were collected on consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing all‐cause 30‐day readmissions and complications were analysed by means of multilevel, multivariable logistic regression modelling using a two‐level hierarchical structure with patients (level 1) nested within hospitals (level 2). Results Data were collected on 8909 patients undergoing cholecystectomy from 167 hospitals. Some 1451 cholecystectomies (16·3 per cent) were performed as an emergency, 4165 (46·8 per cent) as elective operations, and 3293 patients (37·0 per cent) had had at least one previous emergency admission, but had surgery on a delayed basis. The readmission and complication rates at 30 days were 7·1 per cent (633 of 8909) and 10·8 per cent (962 of 8909) respectively. Both readmissions and complications were independently associated with increasing ASA fitness grade, duration of surgery, and increasing numbers of emergency admissions with gallbladder disease before cholecystectomy. No identifiable hospital characteristics were linked to readmissions and complications. Conclusion Readmissions and complications following cholecystectomy are common and associated with patient and disease characteristics
