Autobuses AGA de Colombia S.A. como parte de su proceso empresarial, ha trazado elementos diferenciadores para la proyección y el desarrollo de su proyecto, buscando en forma experimental una línea alternativa frente a la clásica de la administración; dando importancia desde sus inicios, a la participación de las personas involucradas en el proyecto, como eje fundamental de desarrollo del mismo. Bajo una serie de conceptos de pensamiento estratégico y entendiendo la organización como un organismo vivo, esta investigación plantea retos, no sólo para el estudio de este caso, sino para encontrar elementos conceptuales que ayuden a su desarrollo futuro.

El presente trabajo pretende enfocarse en la gestión de Crédito y Cobranzas de la empresa AGA S.A., la misma que según el organigrama estructural forma parte del área financiera. Considerando que el 96% de las ventas totales de la compañía son efectuadas a crédito, el porcentaje de contribución de éstas en los resultados de la compañía se da en la misma proporción, razón por la cual se hace indispensable una administración adecuada y recaudación oportuna de estos recursos en poder de terceros, así como también alcanzar niveles óptimos de productividad y calidad que reflejen un incremento en la rentabilidad. Esta es la razón de ser del presente documento, en el cual, a través de técnicas y herramientas adecuadas descritas en los capítulos 1 y 2 se pretende identificar todas aquellas actividades que no aportan valor agregado para la organización, tareas manuales muy operativas e innecesarias que estén ocasionando cuellos de botella; así como también se proyecta realizar una simulación de la situación luego de implantar las mejoras, lo cual se puede visualizar en los capítulos 3 y 4. Finalmente, se entregará a la organización una propuesta de alternativas a implantarse para mejorar el proceso de crédito y cobranzas tanto en tiempos como en calidad.

Denna historieuppsats (15hp) handlar om aga- och skoldisciplinsfrågorna i den svenska folkskolan. Undersökningens syfte är att granska hur disciplinsfrågorna i folkskolan hanterades före och efter agaförbudet på både nationell och lokal nivå. För att uppnå detta mål har i första hand tre olika källor använts, nämligen 1947 års skoldisciplinutredning, protokoll från Tunabygdens lärarklubb och dess studiecirkel samt Skolöverstyrelsens anvisningar till folkskolelärarna efter att agan hade förbjudits i folkskolan. Skoldisciplinutredningen kom som en följd av protesterna från lärarkåren och Skolöverstyrelsen till ett agaförbud. Disciplinutredningen kom inte fram till något agaförbud utan snarare fram till flera disciplinsfrämjande förslag. I Tunabygdens lärarklubb och dess studiecirkel bedrevs diskussioner som berörde aga, disciplin och fostran överhuvudtaget. Lärarklubben och folkskolestyrelserna i landet var emot ett agaförbud, men inte enbart för rätten i sig att få aga elever, utan också för att de var emot en stark centralstyrning som de upplevde fanns och som ifrågasatte lärarnas yrkesprofession. Skolöverstyrelsens anvisningar kom 1959, året efter agaförbudet och den handlade mycket om skolans och lärarnas fostrande uppgifter. Fungerande disciplin i klassen ansågs vara lika viktig som innan agaförbudet och det handlade om att ändra formerna för denna disciplin. För att upprätthålla ett fungerande disciplin ansåg Skolöverstyrelsen att det var oerhört viktigt att lära känna igen skolbarnet och dess hemförhållanden. För att kontrollera detta hade bl.a. lärare och skolläkare viktiga roller i hemmens hjälp att fostra barnen rätt, då tilltron till barnens föräldrar och uppväxtmiljö var låg från Skolöverstyrelsens sida.

The purpose of this study was to compare the behavior of full-term small-for-gestational age (SGA) with full-term appropriate-for gestational age (AGA) infants in the first year of life. We prospectively evaluated 68 infants in the 2nd month, 67 in the 6th month and 69 in the 12th month. The Bayley Scales of Infant Development-II were used, with emphasis on the Behavior Rating Scale (BRS). The groups were similar concerning the item interest in test materials and stimuli; there was a trend toward differences in the items negative affect, hypersensitivity to test materials and adaptation to change in test materials. The mean of Raw Score was significantly lower for the SGA group in the items predominant state, liability of state of arousal, positive affect, soothability when upset, energy, exploration of objects and surroundings, orientation toward examiner. A lower BRS score was associated with the SGA group in the 2nd month.

Background: Versutoxin (delta-ACTX-Hv1) is the major component of the venom of the Australian Blue Mountains funnel web spider, Hadronyche versuta. delta-ACTX-Hv1 produces potentially fatal neurotoxic symptoms in primates by slowing the inactivation of voltage-gated sodium channels; delta-ACTX-Hv1 is therefore a useful tool for studying sodium channel function. We have determined the three-dimensional structure of delta ACTX-Hv1 as the first step towards understanding the molecular basis of its interaction with these channels. Results: The solution structure of delta-ACTX-Hv1, determined using NMR spectroscopy, comprises a core beta region containing a triple-stranded antiparallel beta sheet, a thumb-like extension protruding from the beta region and a C-terminal 3(10) helix that is appended to the beta domain by virtue of a disulphide bond. The beta region contains a cystine knot motif similar to that seen in other neurotoxic polypeptides. The structure shows homology with mu-agatoxin-l, a spider toxin that also modifies the inactivation kinetics of vertebrate voltage-gated sodium channels. More surprisingly, delta-ACTX-Hv1 shows both sequence and structural homology with gurmarin, a plant polypeptide. This similarity leads us to suggest that the sweet-taste suppression elicited by gurmarin may result from an interaction with one of the downstream ion channels involved in sweet-taste transduction. Conclusions: delta-ACTX-Hv1 shows no structural homology with either sea anemone or alpha-scorpion toxins, both of which also modify the inactivation kinetics of voltage-gated sodium channels by interacting with channel recognition site 3. However, we have shown that delta-ACTX-Hv1 contains charged residues that are topologically related to those implicated in the binding of sea anemone and alpha-scorpion toxins to mammalian voltage-gated sodium channels, suggesting similarities in their mode of interaction with these channels.

Context The association between large for gestational age (LGA) phenotype, postnatal growth and cardiometabolic risk (CMR) in adult life remains unclear. The role of IGF1 genotype on LGA-related outcomes in adult life is unknown. Aim To assess the postnatal growth, IGF-I levels, CMR and the influence of the 737.738 IGF1 in adults born LGA. Subjects Case-control study (n = 515) nested in a population-based prospective cohort (n = 2063); 117 LGA and 398 gender-matched controls appropriate for gestational age (AGA) subjects. Methods Anthropometry was evaluated at birth, at 9-10 and at 23-25 years old. At the age of 23-25 years, blood pressure (BP), glycaemia, insulinaemia, homeostasis model assessment - insulin resistance, lipids, fibrinogen, and plasma IGF-I and 737.738 IGF1 polymorphism were assessed. Results Large for gestational age subjects remained heavier and taller than AGA at 9-10 and 23-25 years (P < 0.05); at 23-25 years, LGA had greater waist circumference (WC; P < 0.05) and higher BP (P < 0.05) than controls. Body proportionality at birth did not predict metabolic outcome. LGA subjects presenting catch-down of weight in childhood had lower body mass index (BMI; P = 0.001), lower WC (P < 0.05) and lower BP (P < 0.05) at 2325 years. 737.738 IGF-I genotype differed between groups (P < 0.001). Homozygosis for polymorphic alleles was associated with increased odds of LGA (OR: 3.2; 95% CI: 1.5-6.9), higher IGF-I (56.9 +/- 16.4 vs 37.7 +/- 16.0 nm; P < 0.01) and lower BP (114/68 vs 121/73 mmHg; P < 0.05). Conclusions Young adults born LGA presented higher BMI, WC and BP and appear to be at higher CMR risk than AGA subjects. The 737.738 IGF1 polymorphism appears to play a role on birth size and LGA-related metabolic outcomes.

There is evidence that intrauterine growth restriction, resulting in newborn girls that are small for gestational age (SGA), may be related to the onset of polycystic ovary syndrome (PCOS). Thus, we studied whether women born SGA have a higher prevalence of PCOS than women born appropriate for gestational age (AGA). This was a prospective birth cohort study of 384 women born at term between June 1, 1978, and May 31, 1979, in Ribeirao Preto, Brazil. After exclusion, 165 women effectively participated in this study, of whom 43 were SGA and 122 were AGA. The prevalence of PCOS was analysed. At a mean age of 29 years, the women agreed to follow the study protocol, which included: anamnesis, physical examination, serum tests [follicle stimulating hormone, luteinizing hormone, total and free testosterone, dehydroepiandrostenedione sulphate, 17-OH-progesterone, fasting insulin, sex steroid-binding globulin (SHBG) and fasting glucose] and pelvic ultrasound. Data regarding gestational age, birthweight, age at menarche and maternal data were obtained from the files of the cohort. The adjusted relative risk (RR) values of the SGA, insulin resistance, body mass index, maternal smoking and parity variables were analysed using Poisson regression with robust adjustment of variance for the prediction of PCOS. The prevalence of PCOS was higher in the SGA group than in the AGA group [adjusted RR = 2.44, 95% CI (1.39-4.28)]. Hyperandrogenism was more prevalent in the SGA women than in the AGA women (P = 0.011). Circulating SHBG was lower in the SGA women than in the AGA women (P = 0.041), but fasting insulinemia was similar in both groups. The prevalence of PCOS in SGA women was twice as high as in AGA women in our study population.

Agapophytinae subf.n. is a highly diverse lineage of Australasian Therevidae, comprising eight described and two new genera: Agapophytus Guerin-Meneville, Acupalpa Krober, Acraspisa Krober, Belonalys Krober, Bonjeania Irwin & Lyneborg, Parapsilocephala Krober, Acatopygia Krober, Laxotela Winterton & Irwin, Pipinnipons gen.n. and Patanothrix gen.n. A genus-level cladistic analysis of the subfamily was undertaken using sixty-eight adult morphological characters and c. 1000 base pairs of the elongation factor-1 alpha (EF-1 alpha) protein coding gene. The morphological data partition produced three most parsimonious cladograms, whereas the molecular data partition gave a single most parsimonious cladogram, which did not match any of the cladograms found in the morphological analysis. The level of congruence between the data partitions was determined using the partition homogeneity test (HTF) and Wilcoxon signed ranks rest. Despite being significantly incongruent in at least one of the incongruence tests, the partitions were combined in a simultaneous analysis. The combined data yielded a single cladogram that was better supported than that of the individual partitions analysed separately. The relative contributions of the data partitions to support for individual nodes on the combined cladogram were investigated using Partitioned Bremer Support. The level of support for many nodes on the combined cladogram was non-additive and often greater than the sum of support for the respective nodes on individual partitions. This synergistic interaction between incongruent data partitions indicates a common phylogenetic signal in both partitions. It also suggests that criteria for partition combination based solely on incongruence may be misleading. The phylogenetic relationships of the genera are discussed using the combined data. A key to genera of Agapophytinae is presented, with genera diagnosed and figured. Two new genera are described: Patanothrix with a new species (Pat. skevingtoni) and Pat. wilsoni (Mann) transferred from Parapsilocephala, and Pipinnipons with a new species (Pip. kroeberi). Pipinnipons fascipennis (Krober) is transferred from Squamopygin Krober and Pip. imitans (Mann) is transferred from Agapophytus. Agapophytus bicolor (Krober) is transferred from Parapsilocephala. Agapophytus varipennis Mann is synonymised with Aga, queenslandi Krober and Aga. flavicornis Mann is synonymised with Aga. pallidicornis (Krober).

Antibodies against gliadin are used to detect celiac disease (CD) in patients. An electrochemical immunosensor for the voltammetric detection of human anti-gliadin antibodies (AGA) IgA and AGA IgG in real serum samples is proposed. The transducer surface consists of screen-printed carbon electrodes modified with a carbon nanotube/gold nanoparticle hybrid system, which provides a very useful surface for the amplification of the immunological interactions. The immunosensing strategy is based on the immobilization of gliadin, the antigen for the autoantibodies of interest, onto the nanostructured surface. The antigen–antibody interaction is recorded using alkaline phosphatase labeled anti-human antibodies and a mixture of 3-indoxyl phosphate with silver ions (3-IP/Ag+) was used as the substrate. The analytical signal is based on the anodic redissolution of the enzymatically generated silver by cyclic voltammetry. The electrochemical behavior of this immunosensor was carefully evaluated assessing aspects as sensitivity, non-specific binding and matrix effects, and repeatability and reproducibility. The results were supported with a commercial ELISA test.
