Computer-assisted two-dimensional preoperative planning for total hip arthroplasty: clinical evaluation.

The purpose of this study is to clinically validate a new two-dimensional preoperative planning software for cementless total hip arthroplasty (THA). Manual and two-dimensional computer-assisted planning were compared by an independent observer for each of the 30 patients with osteoarthritis who underwent THA. This study showed that there were no statistical differences between the results of both preoperative plans in terms of stem size and neck length (<1 size) and hip rotation center position (<5 mm). Two-dimensional computer-assisted preoperative planning provided successful results comparable to those using the manual procedure, thereby allowing the surgeon to simulate various stem designs easily.

Decomposition of differences in PISA results in middle income countries

Programme for International Student Assessment

Comparisons of intensity-duration patterns of physical activity in the US, Jamaica and 3 African countries.

BACKGROUND: This difference in how populations living in low-, middle or upper-income countries accumulate daily PA, i.e. patterns and intensity, is an important part in addressing the global PA movement. We sought to characterize objective PA in 2,500 participants spanning the epidemiologic transition. The Modeling the Epidemiologic Transition Study (METS) is a longitudinal study, in 5 countries. METS seeks to define the association between physical activity (PA), obesity and CVD risk in populations of African origin: Ghana (GH), South Africa (SA), Seychelles (SEY), Jamaica (JA) and the US (suburban Chicago). METHODS: Baseline measurements of objective PA, SES, anthropometrics and body composition, were completed on 2,500 men and women, aged 25-45 years. Moderate and vigorous PA (MVPA, min/d) on week and weekend days was explored ecologically, by adiposity status and manual labor. RESULTS: Among the men, obesity prevalence reflected the level of economic transition and was lowest in GH (1.7%) and SA (4.8%) and highest in the US (41%). SA (55%) and US (65%) women had the highest levels of obesity, compared to only 16% in GH. More men and women in developing countries engaged in manual labor and this was reflected by an almost doubling of measured MPVA among the men in GH (45 min/d) and SA (47 min/d) compared to only 28 min/d in the US. Women in GH (25 min/d), SA (21 min/d), JA (20 min/d) and SEY (20 min/d) accumulated significantly more MPVA than women in the US (14 min/d), yet this difference was not reflected by differences in BMI between SA, JA, SEY and US. Moderate PA constituted the bulk of the PA, with no study populations except SA men accumulating > 5 min/d of vigorous PA. Among the women, no sites accumulated >2 min/d of vigorous PA. Overweight/obese men were 22% less likely to engage in manual occupations. CONCLUSION: While there is some association for PA with obesity, this relationship is inconsistent across the epidemiologic transition and suggests that PA policy recommendations should be tailored for each environment.

La técnica de rejilla es un instrumento de evaluación de las dimensiones y estructura del significado personal que se deriva de la teoría de los constructos personales. Tanto en la versión original de G. A. Kelly (1955) como en sus continuas actualizaciones, esta técnica pretende captar la forma en que una persona da sentido a su experiencia en sus propios términos. No se trata, por tanto, de un test convencional, sino de una forma de entrevista estructurada orientada a explicitar y analizar los constructos con los que la persona organiza su mundo. De la entrevista se genera una matriz de datos que se somete a varios análisis para revelar su estructura implícita. El programa RECORD ofrece los resultados de una forma clara y proporciona además una serie de gráficos de fácil interpretación. Todo ello permite dibujar la estructura del mapa cognitivo del sujeto desde su propia semántica, culminando así, con rigor metodológico, una vieja aspiración fenomenológica. Se trata de un instrumento muy 'flexible que puede adaptarse a diversas áreas de aplicación: evaluación individual, grupal, familiar y de pareja, intervención psicoeducativa, asesoramiento vocacional, investigación de mercados, asesoramiento empresarial, investigación terapéutica, estudio de la estructura cognitiva de la personalidad, etc.

Domestic architecture and social differences in North-Eastern Iberia during the iron age (c.525-200 BC)

This paper is concerned with the organization of societies in north-eastern Iberia (present-day Catalonia) during the Iron Age, using data provided by domestic architecture and settlement organization. I offer an analysis of the social differences detected in the dwellings based on a sample of houses excavated at different types of settlement. Although many Iberian houses had simple layouts and small surface areas, some larger dwellings at the main sites are distinguished by the shape of their ground plans, their surface areas, architectural features, and central locations; these houses are believed to be the residences of the Iberian elite. Such dwellings are not found at all sites and the data suggest that there was a relationship between the category of the settlement (or its function) and the types of dwelling in it.

Cultural differences affecting claim handling process and perceived quality in Finnish-Japanese paperboardbusiness

Tutkimuksen tavoitteena oli selvittää Suomen ja Japanin välisten kulttuurierojen vaikutus valitustenkäsittelyprosessiin ja laatukäsityksiin case-yrityksen ja sen asiakkaiden välillä. Teoreettisen viitekehyksen muodostamisessa käytettiin näkemyksiä kulttuurista, kulttuurienvälisestä viestinnästä, valitustenkäsittelystä ja laatukäsityksistä. Kulttuurierojen tarkastelemiseksi esiteltiin kulttuurien ulottuvuuksia eritteleviä viitekehyksiä ja kulturaalisten tekijöiden vaikutusta viestintään. Suomen ja Japanin kulttuureja esiteltiin myös yksityiskohtaisemmin aikaisempien tutkimusten valossa. Työn empiirisessä osassa tutkittiin case-yrityksen sisäisiä sekä yrityksen ja sen asiakkaiden välisiä näkemyseroja. Tutkimus suoritettiin laadullisena case-tutkimuksena, jossa tarkasteltiin myös toimenpiteitä case-yrityksen liiketoimintaympäristön parantamiseksi. Tarvittava tieto kerättiin kirjallisuudesta, artikkeleista, taustahaastatteluilla sekä haastattelemalla yrityksen henkilöstöä Suomessa ja Japanissa samoin kuin sen japanilaisia asiakkaita. Japanilaiset asiakas/toimittaja-suhteet ovat ulkomaalaiselle yritykselle haastava liiketoimintaympäristö. Luottamuksen rakentaminen pitkällä tähtäimellä vaatii läheistä kommunikointia vastapuolen tuntemiseksi, jotta voidaan kehittää tuotteita paremmiksi ja vähentää valituskustannuksia. Laatuajattelua tulee myös yhdenmukaistaa tuotteiden ja palvelujen laadun parantamiseksi.

Polinização natural, manual e autopolinização no pegamento de frutos de pinheira (Annona squamosa L.) em Alagoas

A pinheira (Annona squamosa L) é cultivada no Estado do Alagoas há mais de um século, sendo a principal cultura de valor econômico para centenas de pequenos agricultores. Um dos principais entraves para melhorar a produtividade da cultura é o baixo índice de polinização das flores e a conseqüente produção de frutos. Embora sejam morfologicamente perfeitas, as flores da pinheira apresentam dicogamia protogínica, fenômeno no qual a maturação dos carpelos acontece antes da maturação dos estames, inviabilizando a autofecundação. O presente trabalho objetivou estudar o efeito da polinização natural, manual e da autopolinização no número de frutos fixados em pinheiras. Foram utilizadas plantas de 4 anos de idade oriundas de pés-francos da variedade local "Crioula". As flores foram selecionadas na porção média das árvores em toda a sua circunferência. Foram utilizados os seguintes tratamentos: flores em polinização natural; flores cobertas para induzir a autopolinização; flores polinizadas com pincel usando pólen puro; flores polinizadas com pincel usando 75 % de pólen e 25 % de amido de milho; flores polinizadas com pincel usando 50 % de pólen e 50 % de amido de milho; flores polinizadas com pincel usando 25 % de pólen e 75 % de amido de milho; flores polinizadas com bomba usando pólen puro; flores polinizadas com bomba usando 75 % de pólen e 25 % de amido de milho; flores polinizadas com bomba usando 50 % de pólen e 50 % de amido de milho; flores polinizadas com bomba usando 25 % de pólen e 75 % de amido de milho. Os resultados obtidos mostraram que o uso da polinização artificial com pincel ou com bomba polinizadora aumentou em até 10 vezes o número de frutos fixados em polinização natural ou em autopolinização. A adição do amido de milho seco como veículo para o pólen não reduziu a percentagem de frutos fixados e pode ser utilizado em até 50% da mistura sem reduzir a eficiência na polinização com pincel e em até 75% com bomba.

Differences in pharmaceutical consumption and expenses between immigrant and Spanish-born populations in Lleida, (Spain): a 6-months prospective observational study

Background: There are few studies comparing pharmaceutical costs and the use of medications between immigrants and the autochthonous population in Spain. The objective of this study is to evaluate whether there are differences in pharmaceutical consumption and expenses between immigrant and Spanish-born populations. Methods: Prospective observational study in 1,630 immigrants and 4,154 Spanish-born individuals visited by fifteen primary care physicians at five public Primary Care Clinics (PCC) during 2005 in the city of Lleida, Catalonia (Spain). Data on pharmaceutical consumption and expenses was obtained from a comprehensive computerized data-collection system. Multinomial regression models were used to estimate relative risks and confidence intervals of pharmaceutical expenditure, adjusting for age and sex. Results: The percentage of individuals that purchased medications during a six-month period was 53.7% in the immigrant group and 79.2% in the autochthonous group. Pharmaceutical expenses and consumption were lower in immigrants than in autochthonous patients in all age groups and both genders. The relative risks of being in the highest quartile of expenditure, for Spanish-born versus immigrants, were 6.9, 95% CI = (4.2, 11.5) in men and 5.3, 95% CI = (3.5, 8.0) in women, with the reference category being not having any pharmaceutical expenditure. Conclusion: Pharmaceutical expenses are much lower for immigrants with respect to autochthonous patients, both in the percentage of prescriptions filled at pharmacies and the number of containers of medication obtained, as well as the prices of the medications used. Future studies should explore which factors explain the observed differences in pharmaceutical expenses and if these disparities produce health inequalities.

Differences in phasic development rate amongst wheat cultivars independent of responses to photoperiod and vernalization. A viewpoint of the intrinsic earliness hypothesis

Differences amongst wheat cultivars in the rate of reproductive development are largely dependent on differences in their sensitivity to photoperiod and vernalization. However, when these responses are accounted for, by growing vernalized seedlings under long photoperiods, cultivars can still differ markedly in time to ear emergence. Control of rate of development by this ‘third factor’ has been poorly understood and is variously referred to as intrinsic earliness, earliness in the narrow sense, basic vegetative period, earliness per se, and basic development rate. Certain assumptions are made in the concept of intrinsic earliness. They are that differences in intrinsic earliness (i) are independent of the responses of the cultivars to photoperiod and vernalization, (ii) apply only to the length of the vegetative period up to floral initiation (as suggested by several authors), (iii) are maintained under different temperatures, measured either in days or degree days. As a consequence of this, the ranking of cultivars (from intrinsically early to intrinsically late) must be maintained at different temperatures. This paper, by the re-analysis of published data, examines the extent to which these assumptions can be supported. Although it is shown that intrinsic earliness operates independently of photoperiod and vernalization responses, the other assumptions were not supported. The differences amongst genotypes in time to ear emergence, grown under above-optimum vernalization and photoperiod (that is when the response to these factors is saturated), were not exclusively due to parallel differences in the length of the vegetative phase, and the length of the reproductive phase was independent of that of the vegetative phase. Thus, it would be possible to change the relative allocation of time to vegetative and reproductive periods with no change in the full period to ear emergence. The differences in intrinsic earliness between cultivars were modified by the temperature regime under which they were grown, i.e. the difference between cultivars (both considering the full phase to ear emergence or some sub-phases) was not a constant amount of time or thermal time at different temperatures. In addition, in some instances genotypes changed their ranking for ‘intrinsic earliness’ depending on the temperature regime. This was interpreted to mean that while all genotypes are sensitive to temperature they differ amongst themselves in the extent of that sensitivity. Therefore, ‘intrinsic earliness’ should not be considered as a static genotypic characteristic, but the result of the interaction between the genotype and temperature. Intrinsic earliness is therefore likely to be related to temperature sensitivity. Some implications of these conclusions for plant breeding and crop simulation modelling are discussed.
