The effects of place of residence on tourist motivations: a revised case of the Urban Quadrangle of Minho

This study seeks to capture the underlying reasons for the travel decisions of residents of the Urban Quadrangle of Minho (composed of the municipalities of Barcelos, Braga, Guimarães, and Vila Nova de Famalicão). The aim of the research is three-fold. Firstly, the study identifies the push and pull motivational factors of residents of the Urban Quadrangle of Minho. Secondly, the study examines whether there are differences between the tourist motivations of residents of the four different municipalities of the Urban Quadrangle. Finally, the study investigates if there are any differences in the motivations of those who choose national and international destinations. The methodology comprises quantitative research based on questionnaires administered in 2012 to residents of the Urban Quadrangle of Minho. A principal component factor analysis is employed to identify six push and seven pull factors. The comparison of the mean scores of these factors across municipalities and across residents that choose national and international destinations reveals that the most valued and least valued factors are common to all four municipalities and both groups of residents (that choose national and international destinations).

Travel preferences of the residents of Guimarães: a revised model of push and pull motives

The historic center of the Portuguese city of Guimarães is a world heritage site (UNESCO) since 2001, having hosted the European Capital of Culture (ECOC) in 2012. In this sense, Guimarães has made a major effort in promoting tourism, positioning itself as an urban and cultural tourism destination. The present paper has two objectives. The first, to examine if an existing push and pull motivation model finds statistical support with regard to the population of the municipality of Guimarães, a cultural tourism destination. The second, to study the role that important socio-demographic variables, such as gender, age, and education, play in determining travel motivations of residents from this municipality. Insight on tourism motivation may be an important policy tool for tourism planners and managers in the development of products and marketing strategies. The empirical analysis is undertaken based on questionnaires administered in 2012 to residents of Guimarães. The present study shows that gender, age and education make a difference with regard to travel motivations.

Gender wage and productivity differentials in the Portuguese tourism industry

The objective of this paper is to provide empirical evidence on the determinants of gender wage inequality in the Portuguese tourism industry. Relying on firm level wage equations and production functions, gender wage and productivity differentials are estimated and then compared in order to infer whether observed gender disparities are justifiable on the grounds that women are relatively less productive than men, or instead disparities are due to gender wage discrimination. This approach is applied to tourism industry data gathered in the matched employer-employee data set Quadros de Pessoal (Employee Records). The main findings indicate that female employees in the tourism industry in Portugal are less productive than their male colleagues and that gender differences in wages are fully explained by gender differences in productivity.

Tourist motivation of the residents of the Urban Quadrilátero of Minho: a gender analysis

Women are increasingly active in the participation and consumption of tourism, representing a strong and unique market segment. Knowledge of the needs and preferences of female tourists represents a key success factor in the tourism industry. This preliminary study seeks to capture the underlying reasons for the travel decisions of the residents of the Urban Quadrilátero of Minho, investigating their tourist motivations from a gendered perspective. Insight on tourism motivation may be an important policy tool for tourism planners and managers in the development of products and marketing strategies. The empirical analysis is undertaken based on questionnaires administered in 2012 to residents of the Urban Quadrilátero of Minho. Preliminary results do not reveal significant gender differences in the importance that the local residents place on various tourism motivation factors.

Gender, wages, and productivity: an analysis of the tourism industry in northern Portugal

Tourism represents a major economic activity in Portugal, with an enormous wealth and employment growth potential. A significant proportion of jobs in the industry tourism are occupied by women, given that this industry is characterized by a relatively higher percentage of female employees. Despite the evidence of female progress with regard to their role in the Portuguese labor market, women continue to earn less than their male counterparts. This is clearly the case of the tourism industry, where statistics reveal a persistent gender wage gap. The objective of this paper is to provide empirical evidence on the determinants of gender wage inequality in the tourism industry in northern Portugal. Relying on firm-level wage equations and production functions, gender wage and productivity differentials are estimated and then compared. The comparison of these differentials allows inferring whether observed wage disparities are attributable to relatively lower female productivity, or instead disparities are due to gender wage discrimination. This approach is applied to tourism industry data gathered in the matched employer-employee data set Quadros de Pessoal (Employee Records). The main findings indicate that female employees in the tourism industry in northern Portugal are less productive than their male colleagues and that gender differences in wages are fully explained by gender differences in productivity.

Uniformity of liquid distribution in the canopy of the bean plant, using the spectrophotometric analysis

Fungal diseases are important factors limiting common bean yield. White mold is one of the main diseases caused by soil pathogens. The objective of this study was to quantify the distribution of a fungicide solution sprayed into the canopy of bean plants by spectrophotometry, using a boom sprayer with and without air assistance. The experiment was arranged in a 2 x 2 x 2 factorial (two types of nozzles, two application rates, and air assistance on and off) randomized block design with four replications. Air assistance influenced the deposition of solution on the bean plant and yield increased significantly with the increased rate of application and air assistance in the boom sprayer.

Estimativas de parâmetros genéticos e correlações entre caracteres fenológicos e morfoagronômicos em feijão-caupi

Mensurar a variabilidade genética e conhecer as correlações entre caracteres de interesse para seleção numa população constitui uma das etapas iniciais em um programa de melhoramento genético. Com o objetivo de avaliar o potencial para o melhoramento genético de uma população composta por 19 genótipos de feijão-caupi de porte ereto e semiereto, entre variedades comerciais e linhagens avançadas, foram estimados parâmetros genéticos e fenotípicos e correlações entre caracteres fenológicos e morfoagronômicos da população. O experimento foi conduzido na área experimental da Universidade Estadual de Mato Grosso do Sul, em Aquidauana, no período da seca do ano agrícola 2007/2008. Foram avaliados os caracteres: dias para o florescimento (DF), dias para a maturação (DM), massa de 100 grãos (MCG), comprimento de vagem (CV), massa de vagem (MV), número de grãos por vagem (NGV) e produtividade de grãos secos (PROD). Verificou-se efeito significativo de genótipos para todas as características indicando existência de variabilidade. O maior valor da estimativa do coeficiente de variação genética foi obtido para PROD, que também apresentou o mais alto valor de coeficiente b, 2,05, indicando condição favorável para seleção desse caráter. Dentre os demais caracteres apenas para DM o valor do coeficiente b foi superior a um. Foram observadas correlações genéticas positivas e significativas entre todos os caracteres e PROD, sendo as mais elevadas com DF, MV e NGV. Concluiu-se que a população apresentou potencial para o melhoramento genético e que aumento da produtividade de grãos pode ser obtido principalmente para genótipos mais tardios.

The main benefits associated with health and safety management systems certification in Portuguese small and medium enterprises post quality management system certification

The purpose of this study is to characterize how Portuguese Small and Medium Enterprises (SMEs) view the Occupational Health and Safety Management Systems (OHSMSs) certification process, after receiving the Quality Management System (QMS) certification. References were based on the ISO 9001 standard for a QMS and OHSAS 18001 for OHSMS. The method used to evaluate the implemented systems, was by form of questionnaire. Those questioned had to have a certified quality management system, an implemented OHSMS and be a SME. The questionnaire was sent to 300 SMEs; 46 responses were received and validated. Of them, only 12 SMEs had the OHSMS certificate according to OHSAS 18001. Within those 12 companies that participated: 7 SMEs are from the industrial sector; 3 belong to the electricity/telecommunications sector and 2 SMEs are from the trade/services activity sector. The size of the sample was small, but corresponds to Portuguese reality. Moreover, 34 SMEs did not have the OHSMS certificate. The questionnaire requested the main reasons for SMEs to opt for non-certification and it was related with high costs, while the main reasons to certificate were, among others, needed to eliminate or minimize risks to workers. The main benefits that Portuguese SMEs have gained from the referred certifications have been, improved working conditions, ensuring compliance with legislation and better internal communication about risks and hazards. Also presented are the main difficulties in achieving an OHSMS certification including high certification costs, difficulties motivating personnel, difficulties in changing the company’s culture and increased bureaucracy.

Certification and integration of management systems: the experience of Portuguese small and medium enterprises

The purpose of this study was to characterize the situation of Portuguese Small and Medium Enterprises (SMEs) concerning the certification of their Quality Management Systems (QMS), Environmental Management Systems (EMS) and Occupational Health and Safety Management Systems (OHSMS), in their individually form, to identify benefits, drawbacks and difficulties associated with the certification process and to characterize the level of integration that has been achieved. This research was based on a survey carried out by the research team; it was administered to 46 Portuguese SMEs. Our sample comprised 20 firms (43%) from the Trade/Services activity sector, 17 (37%) from the Industrial sector, 5 (11%) from the Electricity/Telecommunications sector and 4 (9%) from the Construction area. All SMEs surveyed were certified according to the ISO 9001 (100%), a quarter of firms were certified according to the ISO 14001 (26.1%) and a few certified by OHSAS 18001 (15.2%). We undertook a multivariate cluster analysis, which enabled grouping variables into homogeneous groups or one or more common characteristics of the SMEs participating in the study. Results show that the main benefits that Portuguese SMEs have gained from the referred certifications have been, among others, an improvement of both their internal organization and external image. We also present the main difficulties in achieving certification. Overall, 7 of the Portuguese SMEs examined indicated that the main benefits of the IMS implementation management included costs reduction, increased employee training and easier compliance of legislation. The respective drawbacks and difficulties are also presented. Finally, we presented the main integrated items in the certified Portuguese SMEs we examined.

Thermal degradation of Pb(Zr0.53Ti0.47)O3/poly(vinylidene fluoride) composites as a function of ceramic grain size and concentration

Poly(vinylidene fluoride)/Pb(Zr0.53Ti0.47)O3,([PVDF]1−x/[PZT]x) composites of volume fractions x and (0–3) type connectivity were prepared in the form of thin films. PZT powders with average grain sizes of 0.2, 0.84, and 2.35 μm in different volume fraction of PZT up to 40 % were mixed with the polymeric matrix. The influence of the inorganic particle size and its content on the thermal degradation properties of the composites was then investigated by means of thermo-gravimetric analysis. It is observed that filler size affects more than filler concentration the degradation temperature and activation energy of the polymer. In the same way and due to their larger specific area, smaller particles leave larger solid residuals after the polymer degradation. The polymer degradation mechanism is not significantly modified by the presence of the inorganic fillers. On the other hand, an inhibition effect occurs due to the presence of the fillers, affecting particularly the activation energy of the process.

Caracterização física e química de híbridos de tomate em diferentes estádios de maturação produzidos em Baraúna, Rio Grande do Norte

O tomate é uma das olerícolas mais consumidas no mundo. Na região nordeste do Brasil, é comum a comercialização de cultivares industriais para consumo in natura. Este trabalho teve como objetivo avaliar algumas características de qualidade de dois híbridos de tomate industrial ('Mariana' e 'SM -16'), em quatro estádios de maturação (verde - 1; salada - 2; colorido - 3; vermelho - 4). Após a colheita, os frutos foram transportados para o Laboratório de Tecnologia de Alimentos da Universidade Federal Rural do Semi-Árido, onde foram selecionados de acordo com a uniformidade de maturação e avaliados de acordo com diâmetro longitudinal e transversal, massa de matéria fresca, firmeza da polpa, sólidos solúveis, pH, vitamina C e açúcares totais. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 2 x 4 (dois cultivares e quatro estádios de maturação). Os dados foram submetidos análise de variância e as médias comparadas pelo teste de Tukey, a 5%. Observaram-se diferenças na qualidade física e química dos frutos, entre híbridos e entre estádios de maturação. A massa de matéria fresca dos frutos, o diâmetro transversal e a firmeza da polpa dos tomates pertencentes ao híbrido 'SM-16' foram superiores aos do híbrido 'Mariana'. Houve aumento da massa de matéria fresca até o estádio de maturação 3 e decréscimo da firmeza e do pH da polpa, com o amadurecimento dos frutos. O teor de vitamina C dos frutos aumentou do estádio 1 para o 2, e o híbrido 'Mariana' apresentou maior teor de vitamina C.

Crescimento da mandioca e plantas daninhas em resposta à adubação fosfatada

Os fertilizantes podem ser usados para alterar as relações de competitividade, de modo a favorecer as espécies cultivadas, desde que as espécies competidoras apresentem respostas diferenciadas à aplicação de nutrientes. Por essas razões, objetivou-se, com este trabalho, avaliar o crescimento do picão preto (Bidens pilosa L.), da braquiária (Brachiaria decumbens Stapf) e da mandioca (Manihot esculenta Crantz), cultivados sob diferentes quantidades de fósforo fornecidas no plantio. Para isso, foi conduzido experimento em casa de vegetação, em arranjo fatorial 3x4, sendo o primeiro fator constituído pelas espécies estudadas, combinadas com quatro níveis de adubação fosfatadas (0, 80,800 e 4.000 kg ha-1 de P2O5), no delineamento em blocos casualizados, com cinco repetições. A aplicação do fertilizante fosfatado promoveu maior crescimento das espécies avaliadas, sendo que a mandioca apresentou maior crescimento da parte área com o aumento da disponibilidade de fósforo. De maneira geral, as plantas daninhas apresentaram maiores respostas às menores doses de fósforo.

Conservação de pinha com uso de atmosfera modificada e refrigeração

Os frutos da pinheira possuem limitações para sua distribuição a mercados distantes, por causa do rápido amadurecimento, que os torna muito macios, de difícil manuseio sem a ocorrência de danos e de conservação extremamente reduzida. O objetivo deste trabalho foi avaliar a influência do filme de policloreto de vinila (PVC), associado às temperaturas de refrigeração, na conservação pós-colheita da pinha. Os frutos foram selecionados, lavados, sanitizados e acondicionados em bandejas de isopor, com, ou sem, envolvimento de película de policloreto de vinila, e conservados a 12 e 25 ºC. Foram avaliados: cor da casca, firmeza, perda de matéria fresca, sólidos solúveis, acidez titulável, açúcares totais e amido. Os frutos conservados a 12 ºC, com policloreto de vinila, mantiveram a coloração verde da casca até o 18º dia, apresentaram menor perda de massa de matéria fresca e firmeza da casca e menor teor de sólidos solúveis e acidez titulável, em relação aos frutos armazenados a 25 ºC. A utilização da embalagem, associada à temperatura de 12 ºC, permite um período seguro de 18 dias de conservação, com adequada manutenção dos atributos físicos e químicos. Os frutos armazenados a 25 ºC conservaram-se por seis dias. A película de PVC, associada ao armazenamento de 12 ºC, pode ser utilizada para atrasar o amadurecimento dos frutos por 18 dias, mantendo sua qualidade. Os frutos que permaneceram armazenados, por seis dias, a 25 ºC com, ou sem, PVC, não apresentaram características físicas e químicas desejáveis.
