Regular maps of high density

A regular map is a surface together with an embedded graph, having properties similar to those of the surface and graph of a platonic solid. We analyze regular maps with reflection symmetry and a graph of density strictly exceeding 1/2, and we conclude that all regular maps of this type belong to a family of maps naturally defined on the Fermat curves x^n+y^n+z^n=0, excepting the one corresponding to the tetrahedron.Comment: 13 pages, 4 figure

Generating ellipsis using discourse structures

This article describes an effort to generate elliptic sentences, using Dependency Trees connected by Discourse Relations as input. We contend that the process of syntactic aggregation should be performed in the Surface Realization stage of the language generation process, and that Dependency Trees with Rhetorical Relations are excellent input for a generation system that has to generate ellipsis. We also propose a taxonomy of the most common Dutch cue words, grouped according to the kind of discourse relations they signal

The impact of smallholder commercialisation of organic crops on food consumption patterns, dietary diversity and consumption elasticities

The impact of smallholder commercialisation on food consumption patterns in a rural community of South Africa was investigated. The dietary diversity, nutrient intakes and consumption patterns of certified, partially certified and non-members of an organic farmers’ organisation were compared. Engagement in certified commercial organic farming promoted comparatively greater dietary diversity and improved nutrient intakes. While smallholder agriculture commercialisation has the potential to improve food consumption patterns and food quality through increased income and labour opportunities, caution should be exercised before claiming that such commercialisation can alleviate food insecurity and solve hunger in rural South Africa.agriculture, growth, smallholder, consumption, nutrition, Food Security and Poverty,

The Impact of Small Holder Commercialisation of Organic Crops on Food Consumption Patterns in KwaZulu-Natal, South Africa

The impact of smallholder commercialisation on food consumption patterns in a rural community of South Africa was investigated. The consumption patterns, dietary diversity and nutrient intakes of certified and partially certified members of an organic farmers' organisation were compared to data from a random sample of non-member households. Two consecutive survey rounds (n = 200) conducted in November 2004 and March 2005 enabled comparison of dietary diversity, nutrient adequacy (in terms of per household adult female equivalents for energy, iron, and vitamin A) and expenditure elasticities between seasons. Households with members engaged in certified comm ercial organic farming enjoyed greater dietary diversity, improved nutrient intakes com pared to households with members in conversion to organic production and households not engaged in commercial organic farming. Farm and non-farm income strongly and positively influenced nutritional adequacy for households of partially certified and certified members of the organisation. Marked differences in expenditure elasticities were found between the three groups. The results suggested that commercialisation of small holder agriculture has potential to improve food consumption patterns and food quality directly through income generated and indirectly through increased labour opportunities that result in wages and inkind food transfers. While commerciali sation of small holder agriculture shows potential for improving nutrition, caution should be exercised before claiming that such commercialisation can alleviate food insecurity and solve hunger in South Africa.food consumption, nutrition, farm households, small holder, Food Consumption/Nutrition/Food Safety, D1, Q12,

Expenditure elasticities for rural households in the Embo ward, Umbumbulu, KwaZulu-Natal

Household consumption patterns were investigated to determine the impact of an income shock on household expenditure and to establish the potential for demand-led growth in a rural area of KwaZulu-Natal. Household consumption data were collected from sample households in the Embo ward of Umbumbulu, KwaZulu-Natal during October 2004 and March 2005. Budget shares and expenditure elasticities were estimated for household consumption categories for the two study periods, allowing for a comparison of expenditure elasticities between the two seasons. Results suggest that expenditure elasticities for consumer expendables, durables and transport were highly elastic, while expenditure elasticities for the aggregate food category were negative (October) and highly inelastic (March). Analysis of the expenditure categories of tradable and non-tradable goods and services showed expenditure on tradable non-farm goods and services to have the greatest potential for demand-led growth with expenditure elasticities of 2.88 and 2.91, respectively. The category of non-tradable non-farm goods and services was not statistically significant for both periods and the category non-tradable farm goods and services was not statistically significant for October. A seasonal difference in expenditure patterns was apparent, suggesting that responses to income changes vary at different times of the year.Expenditure elasticities, demand-led growth, Umbumbulu region, KwaZulu-Natal, Consumer/Household Economics,

Transcription analysis of apple fruit development using cDNA microarrays

The knowledge of the molecular mechanisms underlying fruit quality traits is fundamental to devise efficient marker-assisted selection strategies and to improve apple breeding. In this study, cDNA microarray technology was used to identify genes whose expression changes during fruit development and maturation thus potentially involved in fruit quality traits. The expression profile of 1,536 transcripts was analysed by microarray hybridisation. A total of 177 genes resulted to be differentially expressed in at least one of the developmental stages considered. Gene ontology annotation was employed to univocally describe gene function, while cluster analysis allowed grouping genes according to their expression profile. An overview of the transcriptional changes and of the metabolic pathways involved in fruit development was obtained. As expected, August and September are the two months where the largest number of differentially expressed genes was observed. In particular, 85 genes resulted to be up-regulated in September. Even though most of the differentially expressed genes are involved in primary metabolism, several other interesting functions were detected and will be presented

LIVED ACADEMIC AND SPIRITUAL LIFE EXPERIENCES THROUGH SONGS OF THEOLOGY STUDENTS

Songs are believed to contribute to the success of students not only in their academiclife (Alisaari & Heikkola, 2016; Ashtiani & Zafarghani, 2015; & Rafiee, Kassaian,& Dastjerdi, 2010) but spiritual life (White, 2014) as well. The purpose of this studywas to examine the lived academic and spiritual life experiences through songs oftheology students. This phenomenological study, with 35 theology students from aprivate university in West Indonesia as participants, generated four themes whichinclude God’s presence, God’s love, self-disposition, and positive learning. It istherefore recommended that tertiary teachers employ spiritual-uplifting songs for theenhancement of both academic and spiritual life aspects of the learner

The Laughing Classroom: Humor, Teaching, and Learning

Diverse strategies are employed nowadays to ascertain effective teaching- learning process. Among these methods chosen to achieve desired result is the making use of humor—a teaching approach which has been discerned as an effective way of creating a more productive teaching and learning, may it be language. This paper discusses the place and importance of humor to teachers, learners, and education as a whole. Barriers and guidelines to using humor are also discussed. The Biblical foundation of humor stresses the benefits humor (laughter) gives.Diverse strategies are employed nowadays to ascertain effective teaching- learning process.

Fermentation of animal components in strict carnivores: a comparative study with cheetah fecal inoculum

The natural diet of felids contains highly digestible animal tissues but also fractions resistant to small intestinal digestion, which enter the large intestine where they may be fermented by the resident microbial population. Little information exists on the microbial degradability of animal tissues in the large intestine of felids consuming a natural diet. This study aimed to rank animal substrates in their microbial degradability by means of an in vitro study using captive cheetahs fed a strict carnivorous diet as fecal donors. Fresh cheetah fecal samples were collected, pooled, and incubated with various raw animal substrates (chicken cartilage, collagen, glucosamine-chondroitin, glucosamine, rabbit bone, rabbit hair, and rabbit skin; 4 replicates per substrate) for cumulative gas production measurement in a batch culture technique. Negative (cellulose) and positive (casein and fructo-oligosaccharides; FOS) controls were incorporated in the study. Additionally, after 72 h of incubation, short-chain fatty acids (SCFA), including branched-chain fatty acids (BCFA), and ammonia concentrations were determined for each substrate. Glucosamine and glucosamine-chondroitin yielded the greatest OM cumulative gas volume (OMCV) among animal substrates (P < 0.05), whereas total SCFA production was greatest for collagen (P < 0.05). Collagen induced an acetate production comparable to FOS and a markedly high acetate-to-propionate ratio (8.41:1) compared to all other substrates (1.67:1 to 2.97:1)
