Authors: Grattan Emily , Woodbury Michelle
Published: November 2019

Date Presented 04/05/19

Nonuse of the paretic arm is highly prevalent after stroke. In the chronic stage of stroke, individuals with neglect have similar patterns of paretic arm use as individuals without neglect when matched for paretic arm motor impairment. These findings highlight how critical it is that stroke rehabilitation therapists address paretic arm nonuse in therapy.

What Type of Barriers Prevent CarFit-Trained OT Practitioners (OTPs) From Participating in CarFit Events or Using the CarFit 1:1 Model?
Authors: Ismail Judith , Miear Laura
Published: November 2019

Date Presented 04/05/19

This study allowed researchers to understand how OTPs trained in the CarFit program utilize the CarFit 1:1 model in practice. Researchers collected 268 surveys. Those who used the 1:1 model reported that it was quick, easy, and helped them determine AE for driving. However, the model will likely be underutilized, as 86 respondents were extremely unlikely to conduct a 1:1 session in the next year due to barriers related to time, billing, and lack of training.

Introduction

Delirium is one of the most prevalent complications in intensive care unit (ICU) patients, which is related to worse clinical outcomes including a longer ICU stay, longer duration of mechanical ventilation, higher mortality rates and increased risk of cognitive impairment. Observational studies have suggested that statins might have a positive effect on delirium status of hospitalized patients. To date, there has been no trial assessing the effect of atorvastatin on delirium status in critically ill patients. Thus, the aim of the current study was to determine the efficacy of atorvastatin on delirium status of patients in the ICU.

Material and methods

In this randomized, double-blind and controlled trial, a total of 90 patients in the general ICU who had delirium for at least 2 days were randomly divided into atorvastatin (40 mg/day) (n = 40) and control (n = 50) groups. Delirium status of the patients was determined twice a day at 10:00 a.m. and 18:00 p.m. using the Richmond Agitation-Sedation Scale (RASS).

Results

Administration 40 mg/day of atorvastatin significantly reduced the mean RASS score and increased delirium-free days at both morning and afternoon time points compared to the control group (p < 0.05).

Conclusions

Administration of atorvastatin had a significant positive effect on delirium status in patients admitted to the ICU.

Traditioneel gezien bedoelt men met onvertaalbaarheid de onmogelijkheid om iets om te zetten van de ene taal naar de andere. Wat als het ook onmogelijk wordt om iets van het ene tekensysteem (bijvoorbeeld tekst of partituur) naar een ander tekensysteem (bijvoorbeeld zegging of uitvoering) om te zetten? Vincent Van Meenen onderzoekt de betekenis van onvertaalbaarheid en maakt tekeningen met waterverf en Chinese inkt telkens wanneer hij op een onvertalbare passage stoot in Shakespeares Macbeth.
¿Cultivar su autonomía? La agroecología de las agricultoras brasileñas
Authors: Hillenkamp Isabelle
Published: November 2019

Heredera de las luchas campesinas, la agroecología surgió en Brasil a partir de la crítica de la inviabilidad socioambiental de la modernización agrícola y de la afirmación de una organización más autónoma y sostenible del trabajo y de la vida. Movimientos de mujeres rurales y organizaciones feministas ocupan este campo político. Comprender el significado de la “agroecología feminista” en Brasil y evaluar su potencial de transformación social requiere volver a los conflictos sobre las relaciones de producción y de género por los cuales se constituyó, y analizar mediante qué prácticas la autonomía se construye (o no). En este artículo, desarrollo este análisis a partir de una investigación de campo con la red de agricultoras agroecológicas de Barra do Turvo, en el sureste del país. A nivel teórico, me apoyo en un enfoque relacional de la autonomía, reconociendo la necesidad de interdependencias en las diferentes esferas de la vida social. Para ello, me baso en una concepción sustantiva y feminista de la economía, haciendo hincapié en todas las formas de trabajo, en particular, las del cuidado.
A Proposed Framework of Corporate Entrepreneurship in Government-linked Companies
Authors: Entebang Harry
Published: November 2019

The growth of public enterprises or government-linked companies (GLCs) has been phenomenal over the years. However, the performance of GLCs remains a major concern. On the other hand, past studies have postulated that there is a strong relationship between corporate entrepreneurship (CE), entrepreneurial orientation (EO) and firm performance. Despite this, viewing GLCs’ performance in the context of CE or EO has received minimal attention among strategic management and entrepreneurship scholars. This paper highlights and discusses the performance of GLCs within the context of CE. Given the role of EO as a direct predictor while proposing CE internal and external factors as moderators of the EO-CE performance relationship in GLCs, a proposed framework of CE within the context of GLCs in Malaysia is proposed.
A New Poe Source

Poe’s mention of Archimedes in a footnote added to “A Descent into the Maelström” in the 1845 edition of the Tales, as well as some items of the “Marginalia” (nos. 87, 94, 101; maybe also nos. 93, 104, 169), were derived from Thomas Thomson’s Sketch of the Progress of Physical Science, as reprinted, bound with Dionysius Lardner’s Course of Lectures, in an 1843 pamphlet. This discovery helps clarify Poe’s use of scientific sources and his attitude toward science.
Unconstrained numerical optimization using real-coded genetic algorithms: a study case using benchmark functions in R from Scratch
Authors: Carmona Cortes Omar Andres , Silva Josenildo Costa da
Published: November 2019

Unconstrained numerical problems are common in solving practical applications that, due to its nature, are usually devised by several design variables, narrowing the kind of technique or algorithm that can deal with them. An interesting way of tackling this kind of issue is to use an evolutionary algorithm named Genetic Algorithm. In this context, this work is a tutorial on using real-coded genetic algorithms for solving unconstrained numerical optimization problems. We present the theory and the implementation in R language. Five benchmarks functions (Rosenbrock, Griewank, Ackley, Schwefel, and Alpine) are used as a study case. Further, four different crossover operators (simple, arithmetical, non-uniform arithmetical, and Linear), two selection mechanisms (roulette wheel and tournament), and two mutation operators (uniform and non-uniform) are shown. Results indicate that non-uniform mutation and tournament selection tend to present better outcomes.

Published: November 2019

Core stability is a reference term for the performance of the deep trunk muscles, which provide functional stability of the lumbopelvic area and control the human body in static and dynamic positions.

The study group consisted of 30 patients between the age of 42 and 76 years (mean=61.4) after total hip arthroplasty (total hip replacement, Group I) and total knee arthroplasty (three-compartment arthroplasty with posterior stabilization of the implant - Group II). In 18 (60%) patients, hip endoprosthesis was performed, whereas in 12 (40%), three-compartment knee endoprosthesis with posterior stabilization has been implanted. In the study group, Rehabilitative Ultrasound Imaging (RUSI) of the transversus abdominis muscle thickness was conducted at rest and in contraction, the transversus abdominis activation ratio was specified, the SF-36 Life Quality Questionnaire was applied and a three-week treatment cycle was performed. The tests were carried out twice, i.e. before and after treatment.

In the group of patients after total hip replacement, the transversus abdominis (TrA) contraction ratio before the beginning of the exercise programme was 0.79±0.06, and after its completion 0.9 ±0.02. The observed difference was statistically significant at p<0.001. In the group of patients after three-compartment knee arthroplasty, the TrA contraction ratio before the beginning of the exercise programme was 0.78±0.09, and after its completion0 0.91±0.02. The difference of these values was statistically significant at the level of p<0.05. The results of the SF-36 questionnaire in both groups indicate improvement in physical functioning. The observed difference was statistically significant at p<0.001.

The performed three-week physiotherapy treatment in conjunction with deep muscle training increases the thickness of the TrA muscle during rest and contraction testing, and increases the transversus abdominis contraction ratio in Rehabilitative Ultrasound Imaging in the study groups. Furthermore, improvement in the level of physical functioning was observed within the studied groups.
The effect of annealing and anisotropic
behaviour on tensile and fatigue
properties of AA 8090
Authors: Abass M.H. , Mahmud F. , Alali M.S. , Abood A.N.
Published: November 2019

Purpose: This paper aims to assess microstructures and mechanical properties of annealed
and un-annealed Al-Li alloys (AA8090) and provide valid information regarding influence of
anisotropy on tensile properties, fatigue lives.
Design/methodology/approach: The methodology included investigating the
influence of annealing on grain size, tensile strength and fatigue lives of AA8090. Optical
microscope, scanning electron microscope and X-ray diffraction were utilized to analyse the
crystallographic texture.
Findings: The results showed that the un-annealed alloy exhibited much finer grain
structure in three directions, namely longitudinal (L) rolling direction, L-45° and Long
transverse (LT) combined with stronger crystallographic texture. Regarding to mechanical
properties, un-annealed alloy presented superior tensile strength with strong anisotropic
behaviour. L and LT grains direction showed highest tensile strength value of 550 MPa and
L-45° showed lowest tensile strength value of 420 MPa. Results of fatigue test revealed that
annealed Al-Li alloy has lower fatigue lives with high influence of test direction on fatigue
properties. Higher variation in fatigue life to failure links with un-annealed alloy over annealed
alloy. Examination of fractured surface showed that the morphology of fractured surface is
a mixture of ductile and brittle fractures in both annealed and un-annealed alloys with more
brittle behaviour in un-annealed alloy.
Research limitations/implications: The main challenge of this work is the determination
of the test direction (test angle in respect to rolling direction), which is necessary to provide
correct information regarding mechanical properties. Further study of low cycle fatigue
can be done in future, which will be an excellent indication to mechanical properties of
this alloy since it provides more understanding to the behaviour of the material and better
comprehend crack propagation and strain stress concentration.
Practical implications: AA8090 alloy is an important candidate for aerospace and
aircraft industries. Influence of annealing heat treatment and rolling direction on mechanical
properties of AA8090 alloy provides more accurate information to the manufacturers who
deal with this alloy.
Originality/value: This study is affording a significant information regarding the effect of
annealing and anisotropic behaviour on mechanical properties of AA8090. To our knowledge,
there are few reports that study this combination of factors on AA8090 alloy.

Investigating Translators’ Work-related Happiness: Slovak Sworn and Institutional Translators as a Case in Point
Authors: Bednárová-Gibová Klaudia , Madoš Branislav
Published: November 2019

This paper reports on an investigation which is part of a comprehensive project aimed at investigating translators’ work-related happiness in various contexts, a subject largely under-researched in contemporary translation studies. The purpose of this pilot cohort study is to determine the perceptions of happiness in two presumably high-profile groups of translators—Slovak sworn translators and Slovak EU translators. To accomplish the aim, comparative and causal perspectives are used. The quantitative analysis, comprising descriptive and correlation analysis, involves data from questionnaires completed by a total of 115 translators belonging to the two groups (83 + 32). The respondents’ perceptions of their work-related happiness are examined and compared, based on their responses to questions revolving primarily around social status variables and parameters of occupational prestige. Based on the gained data, seven hypotheses are tested with quantitative research methods employing contingency tables. Although our findings largely do not corroborate the hypotheses and lead to the identification of crucial differences between the two groups, the analyses also allow us to identify some commonalities. The results of the quantitative analysis are discussed in detail.

O museu na comunidade: património, identidade e desenvolvimento
Authors: Mendes José Amado
Published: November 2019

As questões relacionadas com o património têm vindo a ser frequentemente analisadas, como se pode comprovar pela vasta literatura que lhes tem sido dedicada. Tal deve-se a vários factores, de entre os quais se destacam: o alargamento do conceito de património, nas últimas décadas, ,fez com que aquele passasse a abranger também realidades que, até há pouco, lhes eram estranhas; por outro lado, uma certa globalização, inclusive sob o ponto de vista cultural, desencadeou reacções de sinal contrário, tendentes a reforçar as identidades das comunidades; por último, uma verdadeira explosão museológica tem contribuído para a salvaguarda de parcelas consideráveis do património, em nítido contraste com a parte que outrora era objecto de intervenção. Em consequência de uma certa «patrimoniolização» da realidade e da criação de um número excepcional de museus, as potencialidade destes começaram a evidenciar-se, não só a nível cultural e educativo, mas igualmente no que concerne ao desenvolvimento.
Uma nova perspectiva sobre o património cultural: preservação e requalificação de instalações industriais
Authors: Mendes José Amado
Published: November 2019

Tem-se verificado, nas últimas décadas, uma profunda transformação no conceito tradicional de património cultural. Este, ao democratizar-se, passou a abranger também uma diversificada gama de objectos – que são, simultaneamente, fontes históricas –, inclusive do âmbito do trabalho, do quotidiano e das “coisas banais”. Consequentemente, urge estudar, preservar e reutilizar numerosas estruturas industriais, já desactivadas, mas que apresentam potencialidades para entrarem num novo “ciclo de vida”, continuando ao serviço da comunidade. Torna-se, pois, necessário requalificar certos espaços, urbanos ou rurais, adaptando-os a novas funções, culturais, sociais e/ou económicas. Assim, reforçar-se-á e fomentar-se-á o chamado turismo cultural, já importante, em nossos dias, mas que tenderá a desenvolver-se consideravelmente, a médio e longo prazo.

Published: November 2019

A integração de Portugal na Comunidade Económica Europeia/UniãoEuropeia, a partir de 1 de Janeiro de 1986, constituiu um marco significativo da nossa História recente. Por isso, há que avaliar quais as repercussões de tal integração, sob os diversos pontos de vista. No estudo que se segue, focaremos o assunto apenas no que concerne à indústria transformadora na Região Norte. Começa-se por enquadrar, histórica e geograficamente, a área em estudo, ou seja, a dita Região Norte. Esta integra diversas subregiões, com as suas especificidades, sobretudo em termos de actividades predominantes e do respectivo desenvolvimento económico. No que à indústria diz respeito, destaca-se o Vale do Ave que, por isso mesmo, merece uma atenção especial. Seguidamente, analisam-se os recursos humanos, particularmente no que toca à qualificação escolar dos trabalhadores por conta de outrem e respectiva evolução, no período em foco (1986-1995). A melhoria da qualificação dos efectivos, relativamente à sua formação, tem vindo a repercutir-se nos diversos sectores de actividade, embora de forma desigual em cada um deles. Por último, dedicar-se-á a devida atenção ao desenvolvimento industrial verificado ultimamente, com destaque para os ramos mais significativos: têxtil, vestuário e calçado. Tratando-se do principal pólo de especialização industrial português, estudam-se alguns dos elementos que caracterizam o modelo industrialização em curso, o tipo de empresas mais comum, a qualidade dos produtos, os factores de competitividade e os sinais de mudança.
GAMVIS: a análise de clusters na identificação de semelhanças e diferenças entre concelhos
Authors: Pereira Paulo Almeida
Published: November 2019

A Grande Área Metropolitana de Viseu (GAMVIS) foi uma realidade, criada no final de 2004, integrando 21 concelhos de dois distritos e de três NUTS lll. Após uma introdução ao método de análise de clusters, procede-se ao estudo da forma como se posicionam os vários concelhos da GAMVIS, no que diz respeito a cerca de duzentos indicadores estatísticos, disponíveis no JNE, repartidos pelas mais diversas áreas: território e ambiente, população e condições sociais, economia e finanças, comércio externo, silvicultura, construção e energia e, finalmente, transportes. A caracterização assim efectuada permite identificar as diferenças e as semelhanças entre os concelhos que constituem a GAMVIS, de forma a que possam servir de base aos diversos actores responsáveis pela definição de linhas de orientação estratégica desta região do interior do país, que apresenta indicadores desfavoráveis, quando comparados com outras zonas de Portugal. Uma análise global, em que se conjugam análise de clusters e a análise factorial, permite agrupar os concelhos da GAMVIS em sete clusters que, curiosamente, além das semelhanças, em termos de indicadores, apresentam também afinidades geográficas.

Para a inclusão de crianças e jovens com Necessidades Educativas Especiais (NEE) no ensino regular foram teorizadas e implementadas práticas com vista a estruturar o Programa Educativo Individual (PEI), adequando-o a cada um, dando respostas à sua singularidade. A implementação do uso da Classificação Internacional de Funcionalidade (CIF), como referência para a classificação das NEE, surge com o Decreto-Lei n.º 3/2008, de 7 de janeiro e adota um cariz biopsicossocial criado pela Organização Mundial de Saúde (OMS, 2004). A sua introdução na educação não tem sido pacífica, sobressaindo o debate entre especialistas e autores que alimentam o esgrimir de argumentos a favor e contra a sua utilização. Analisaremos, assim, a CIF, bem como o seu surgimento, a sua estrutura e as opiniões de alguns especialistas.

Authors: Monteiro Catarina , Martins Rosa
Published: November 2019

Introdução: As múltiplas investigações desenvolvidas sobre o apoio social dos Idosos têm demonstrado, que o apoio percebido e o grau de satisfação com ele, é aquele que tem demonstrado exercer efeitos mais fortes e consistentes na saúde, no bem-estar e na qualidade de vida dos mais velhos. Objectivo: Avaliar a satisfação dos idosos da amostra com o seu suporte social, e avaliar em que medida as variáveis sócio demográficas, as variáveis circunstanciais, as variáveis da perceção da saúde e as variáveis sócio culturais influenciam essa satisfação. Metodologia: Foi realizado um estudo transversal, descritivo, correlacional e não experimental, e de cariz quantitativo. A amostra selecionada é do tipo não probabilística por conveniência, constituída por 130 idosos do concelho de Armamar que recorreram ao Balcão de Proximidade do Projecto 3I ́s. Os instrumentos de medida utilizados foram um questionário construído para obter informações sobre os dados sociodemográficos, socioculturais, sobre a perceção da saúde e as caraterísticas circunstanciais e a Escala de Satisfação com o Suporte Social. Resultados: A população estudada é maioritariamente feminina, casada e com uma média de idades de 75,18 anos. Possuem habilitações literárias baixas, (34,6% analfabetos), auferem de escasso apoio institucional e baixos rendimentos. A grande maioria dos idosos (96,2%) reside em casa própria, considera-se autónoma (85,3%) e os níveis de satisfação com o suporte social são moderados em todas as dimensões, sendo mais elevados no item satisfação com amizades (M=16,2). Conclusão: As variáveis com maior influencia na satisfação com o suporte social são: o género, pois os homens possuem níveis de satisfação com o suporte social mais elevados em todas as subescalas
Observação de aulas em contexto de ADD: função classificatória ou emancipatória da classe docente?
Authors: Dias Paula Arnaud
Published: November 2019

Com a crescente complexidade da sociedade atual novos desafios e funções são pedidos às escolas e estas necessitam de desenvolver no seu interior modelos de supervisão colaborativa que promovam uma cultura de trabalho reflexivo e dialogante. Através desta ação e atitude estaremos a estimular o desenvolvimento da autonomia dos docentes e da organização escolar visando a construção de um ensino e de uma escola de qualidade. É dentro deste quadro de referência que surge a observação de aulas no âmbito da avaliação de desempenho (ADD) e fomos investigar de que forma o processo foi implementado e “vivido” em duas escolas onde exercemos a função de avaliadora e avaliada. Nesse sentido, foram analisadas as grelhas de observação de aulas e ouvidos os seus atores educativos (avaliadores e avaliados) relativamente ao impacto que a observação de aulas teve no seu desenvolvimento/crescimento profissional e da organização educativa no seu todo. Pretendeu-se investigar se o processo de observação de aulas, nestas duas organizações, foi monitorizado segundo um modelo de supervisão escolar reflexivo e integrado num projeto de escola ou se apenas se limitou a um mero ato administrativo, burocrático e de avaliação sumativa. Toda a investigação teve como finalidade dar resposta à questão que norteou todo o nosso trabalho: Observação de aulas em contexto de ADD: função classificatória ou emancipatória da classe docente?
Electronic word-of-mouth e a sua influência na intenção de compra dos utilizadores do Facebook
Authors: Teixeira Miguel , Andrade António , Martins Carla
Published: November 2019

Os websites de social media são principalmente impulsionados por conteúdos gerados pelos indivíduos e a sua popularidade exponenciou a capacidade de influência das comunicações interpessoais sobre produtos ou serviços no comportamento dos consumidores entre redes sociais online. Este estudo examinou os determinantes do Electronic Word-of-Mouth (eWOM) transmitido pela lista de contactos no Facebook que influenciam a intenção de compra dos consumidores. O modelo testado é adaptado do modelo Information Acceptance (IACM) de Erkan e Evans (2016). Os objetivos de pesquisa consistem na investigação de características da informação (qualidade e credibilidade de informação), do recetor (atitude em relação à informação e necessidades de informação) e do emissor (credibilidade da fonte) que exercem maior impacto na influência do eWOM no comportamento do consumidor. A utilidade da informação foi considerada como antecedente chave das respostas de comportamento (adoção da informação e intenção de compra). Dados recolhidos através de um questionário online a 294 utilizadores do Facebook residentes em Portugal foram analisados através da técnica de modelação de equações estruturais baseada no método de mínimos quadrados parciais (PLS-SEM). As características do recetor demonstraram ter o maior nível de influência na intenção de compra. A qualidade da informação não demonstrou efeito sobre a intenção de compra. Adicionalmente, a credibilidade da informação apresentou um efeito mediador total sobre a qualidade da informação e a credibilidade da fonte na perceção de utilidade de informação.

Published: November 2019

In December 2015, wilt symptoms on tomato plants (Solanum lycopersicum L.) were observed on vegetable growing perimeters in Sotouboua district in Togo. The disease, manifested by wilting of the youngest leaves followed by wilting and total desiccation of plants who eventually dy, leading to losses of up to 100%, is similar to bacterial wilt. The aim of this study, was to determine the pathogen responsible for the observed symptoms. For this purpose, phytosanitary surveys were carried out on tomato plots in Sotouboua distric, in 2018. During the surveys, Tomato plants infected by wilt and the plots soil samples, were collected on CECODRI project and farmers’ plots in the district. Soil samples were analyzed for the detection of nematodes while, tomato leaves, stems and roots were directly observed under binocular loupe and after incubation in Petri dishes containing filter paper moistened with distilled water to encourage sporulation of phytopathogenic fungi. Infected tomato stems and roots were analyzed by stem-streaming and DAS-ELISA tests using Agdia inc. Ralstonia solanacearum Patho Screen Kit to detect R. solanacearum. The results of the phytosanitary surveys showed that the wilt prevalence was 100% in Sotouboua district with incidence rates of up to 100%. Analysis of diseased samples, using stem-streaming and DAS-ELISA tests, revealed that 85.11% of diseased plants were infected by R. solanacearum. No nematodes were identified in the roots of the infected plants, but in soil samples only a few nematodes were counted. No fungus was found in the plants with wilt symptoms. It appears, therefore that, the wilt on tomato plants in Sotouboua district was caused by R. solanacearum. This, in our knowledge, is the first report on R. solanacearum infection on tomato in Togo.

Aims: The aim of this study was to determine the relevant experiences of the students on teaching strategies used by their teachers in the classrooms; what made these teaching effective; and what suggestions the students can offer to enhance the teaching strategies.

Study Design:  Qualitative-phenomenology.

Place and Duration of Study: Institute of College Education and Graduate Studies (IEGS), Southern Philippines Agri-Business and Marine and Aquatic School of Technology, School year 2018-2019.

Methodology: Included 200 college freshmen taking BSEd Secondary Education and were the first batch graduates of the K-12 program. They were grouped into 40 focus groups. Information were obtained through interview.

Results: Data analysis formulated five themes. Prevalent used strategies discussed the commonly used strategies; improvements gained from strategies looked into the benefits the students obtained; evaluation of ineffective strategies dealt with the irrelevant strategies the teachers used; relevant experiences showed the meaningful encounters of the students to the strategies and suggestions centered on the comments students had offered to improve the use of strategies.   

Conclusion: Strategies are relevant in delivering the lessons. However, strategies should be well-thought before they are used. Thus, teachers need to identify who the learners are. Moreover, teachers should also consider the topic. Various topics require different strategies. Also, teacher needs to discuss thoroughly the marking criteria used. Mark criteria guide students to set their targets and to avoid confusion. Likewise, teacher should always prepare and set plans before coming to class. Further, nearing retiring teachers should not solely rely on their experiences because curriculum changes. Lastly, one of the best ways to know what strategies fit the students is consulting the students themselves. Teachers will not get wrong if they know better their students.

Published: November 2019

Aim: The main aim of this study is to identify the factors affecting the big onion productivity of Hambantota district during the off-season. Moreover, we identify the average productivity per acre from Hambantota district and compare it with the other areas that cultivated the big onion. Further, identify the main issues encountered in big onion cultivation in Hambantota and identify the critical contributing factors for the big onion cultivation in this area.

Place and Duration of Study: During the off seasons in 2015 to 2016 in Hambantota District.

Methodology: Sample data was collected from 201 farmers in Hambantota district. Multiple linear regression model was used to identify the factors affecting the big onion productivity in Hambantota district during the off-season. The normality assumption of the regression model was checked using Kolmogorov–Smirnov test, Shapiro Wilk normality test and Skewness and Kurtosis test. Pearson, Spearman’s Rank and Partial correlation tests were used to check the correlations between variables. Mean absolute percentage error (MAPE) and Symmetrical Mean absolute percentage error (SMAPE) values were used to validate the fitted model.

Results: By the multiple linear regression model main factors affecting the productivity of big onion in Hambantota area were Seasonal Months, Monthly Income, Subsidies Fertilizer and Cultivated Quantity. And the R-squared value was most like to 80% and this means these independent variables were described 80% of the dependent variable.  Model accuracies were reported as 98.48% and 98.49% from MAPE and SMAPE respectively. Therefore, this multiple linear regression model was suitable for this study. Further, the model determined the affected factors for the big onion cultivation in Hambantota district during the off-season.

Conclusion: Hambantota district average productivity was less than other areas. Big onion productivity of Matale is more than 2 times greater than big onion productivity of Hambantota. Off season big onion cultivation in Hambantota district is not very effective because of the average productivity is less than other areas in Sri Lanka.
