Financial Risk Analysis of Portuguese Textile and Tourism Companies

Textile and tourism sectors are two important industries in the Portuguese economy. However, its high exposure to both internal and international economic volatility make the companies operating in these economic sectors particularly vulnerable to economic crises, such as the ones which have been impacting Portugal and the European Union. The objective of this paper is to evaluate and understand the impact of size and age on the financial health of textile and tourism companies, measured by economic indices. An empirical based model is proposed. Its implications are derived and tested on a sample of 4061 Portuguese companies from textile and tourism sectors, during the period 2005-2009. The findings suggest that age has a major impact on the risk of failure, rather than size. Whereas the effect of age is generally positive regarding the financial health of the company, the effect of size is less clear and ultimately depends on the age of the company.

The impact of size and age of the company on assessing financial risk.

Textiles and tourism sectors are two important sectors in Portuguese economy. Its high exposure to both internal and international economy volatility transform the companies operating in these economic sectors especially vulnerable to recent economic crises in Portugal and European Union. The objective of this paper is to evaluate and understand the impact of size and age on the financial health of textile and tourism companies, measured by economic indices. An empirical based model is proposed. Its implications are derived and tested on a sample of 4061 Portuguese companies from textile and tourism sector, during the period 2005-2009. The results conclude that age has a stronger impact on the risk of failure than size. Whereas the effect of age is generally positive regarding the financial health of the company, the effect of size is less clear and depends on the age of the company.

Evaluating the Guimarães 2012 European Capital of Culture: National and International Tourists’ Behaviors and Perceptions

In 2012, Guimarães hosted the European Capital of Culture (ECOC). An evaluation of this event was needed because public, private, and community funds were involved. This analysis considers tourists as external and independent stakeholders who assessed the cultural activities developed during the event as well as the attributes of the city. The main objectives of the research conducted were to assess the visitors` motivations during the hosting of the Guimarães ECOC 2012, their perceptions towards the city and if national and international visitors kept different perceptions of it. For two months, in the summer of 2012, a survey was applied to 390 visitors. The results revealed that hosting the 2012 ECOC was a major contribution towards attracting new visitors to the city (though many of the visitors stayed only for a short period of time). Based on tourists’ perceptions, the tangible heritage was clearly detached from the set of attributes associated to Guimarães, whereas the intangible heritage was less noted. The Portuguese tourists seem to be more prone to value the tangible heritage than the foreign tourists. Overall, Guimarães received a very positive evaluation relating to the city’s image and, as stated by tourists, visiting it was declared to be highly recommended. Following the obtained empirical results, the need for changing the city’s promoted image emerges, which has been too centered on its tangible heritage. In doing so, it is believed that there will be longer overnight stays by visitors.

CAUSE-FIT, POSITIVE ATTITUDES AND BEHAVIORS WITHIN HYBRID COLOMBIAN ORGANIZATIONS

ABSTRACTSocially oriented ventures have provided livelihoods and social recognition to disadvantaged communities in different corners of the world. In some cases, these ventures are the result of Corporate Social Responsibility (CSR) programs. In Latin America, this type of undertaking has responded positively to unmet social needs. The social cause drives these organizations and their human resources and they give high value to organizational cause-fit. This paper presents empirical evidence of the effects of perceived cause-fit on several worker attitudes and behaviors. Psychological contract theory was adopted as theoretical background. Employees working in a hybrid (for-profit/socially oriented) Colombian organization created by a CSR program participated in the survey. Data provided by 218 employees were analyzed using PLS structural equation modeling. The results suggest the ideological components of the employee-employer relationship predict positive attitudes and cooperative organizational behaviors towards hybrid organizations.

Body composition, muscle strength, functional capacity, and physical disability risk in liver transplanted familial amyloidotic polyneuropathy patients

Abstract: Background: Familial amyloidotic polyneuropathy (FAP) is a neurodegenerative disease leading to sensory and motor polyneuropathies, and functional limitations. Liver transplantation is the only treatment for FAP, requiring medication that negatively affects bone and muscle metabolism. The aim of this study was to compare body composition, levels of specific strength, level of physical disability risk, and functional capacity of transplanted FAP patients (FAPTx) with a group of healthy individuals (CON). Methods: A group of patients with 48 FAPTx (28 men, 20 women) was compared with 24 CON individuals (14 men, 10 women). Body composition was assessed by dual-energy X-ray absorptiometry, and total skeletal muscle mass (TBSMM) and skeletal muscle index (SMI) were calculated. Handgrip strength was measured for both hands as was isometric strength of quadriceps. Muscle quality (MQ) was ascertained by the ratio of strength to muscle mass. Functional capacity was assessed by the six-minute walk test. Results: Patients with FAPTx had significantly lower functional capacity, weight, body mass index, total fat mass, TBSMM, SMI, lean mass, muscle strength, MQ, and bone mineral density. Conclusion: Patients with FAPTx appear to be at particularly high risk of functional disability, suggesting an important role for an early and appropriately designed rehabilitation program.

The aim of this study is to identify potential risk factors of non-compliance with treatment when it is implemented by family in amblyopic children. Setting: a quantitative transversal study was performed in a public hospital and in a private clinic in Lisbon.

Modelos de risk based inspection e risk based inspection and maintenance aplicados a sistemas de produção de energias renováveis

A utilização de recursos energéticos renováveis apresenta-se como um caminho vital para a humanidade alcançar um desenvolvimento sustentável. Nesta campanha, a energia eólica surge como um dos principais vectores de orientação tendo evoluído de forma quase exponencial nos últimos anos. No entanto, apesar da sua relativa maturidade, esta tecnologia enfrenta ainda alguns problemas e desafios. Não obstante a experiência empírica da indústria eólica, adquirida nos últimos trinta anos e dos esforços para melhorar a fiabilidade operacional das turbinas, as taxas de falha ainda se apresentam elevadas. Face às correntes práticas de Manutenção das turbinas e parques eólicos e às características de falha, (por vezes catastróficas), existe a necessidade de optimizar as estratégias de manutenção das turbinas eólicas e reduzir os custos durante o ciclo de vida, de modo a maximizar o retorno do investimento. Descreve-se neste trabalho o estado do conhecimento actual face ao objectivo pretendido, a recolha de dados reais da operação e Manutenção, a aplicabilidade dos modelos escolhidos para obtenção da probabilidade de falha, e as consequências e avaliação do risco. Assim, desenvolveu-se uma ferramenta de apoio à decisão, baseada em Modelos de RBI (Risk Based Inspection) e RBIM (Risk Based Inspection and Maintenance) aplicados a turbinas eólicas.

Risk Aversion in a Mixed-Integer Nonlinear Approach to Support Decision-Making for a Hydro Power Producer

In this paper, a mixed-integer nonlinear approach is proposed to support decision-making for a hydro power producer, considering a head-dependent hydro chain. The aim is to maximize the profit of the hydro power producer from selling energy into the electric market. As a new contribution to earlier studies, a risk aversion criterion is taken into account, as well as head-dependency. The volatility of the expected profit is limited through the conditional value-at-risk (CVaR). The proposed approach has been applied successfully to solve a case study based on one of the main Portuguese cascaded hydro systems.

Active and passive behaviors of soft tissues: Pelvic floor muscles

: A new active-contraction visco-elastic numerical model of the pelvic floor (skeletal) muscle is presented. Our model includes all elements that represent the muscle constitutive behavior, contraction and relaxation. In contrast with the previous models, the activation function can be null. The complete equations are shown and exactly linearized. Small verification and validation tests are performed and the pelvis is modeled using the data from the intra-abdominal pressure tests

Risk factors for basal cell carcinoma: a case-control study

A controlled trial was performed with the purpose of investigating which factors could be considered of significant risk for the development of basal cell carcinoma. A total of 259 cases of basal cell carcinoma diagnosed from July 1991 to July 1992 were compared with 518 controls matched for age and sex. All subjects in both groups were white. Protocol data were submitted to statistical analysis by the chi-square test and by multiple conditional logistic regression analysis and the following conclusions were reached: 1) light skin color (types I and II of the Fitzpatrick classification), odds ratio of 2.8; outdoor work under constant sunlight, odds ratio of 5.0; the presence of actinic lesions due to exposure to the sun, odds ratio of 4.9, are risk factors perse. 2) Type III skin in the Fitzpatrick classification only represents a risk factor when the patient reports a history of intense sunburns, but not in the absence of such a history. 3) Sunburns per se do not represent a risk factor althorig the point made in item 2 of these conclusions is valid. 4) Other suspected risk factors whose significance was not confirmed by multiple conditioned logistic regression analysis were: residence in rural areas, light eyes and blond hair color, extent of the awareness of the "sun x skin cancer" relationship, familial occurrence of skin cancer, excessive exposure to the sun, and freckles appearing in childhood.

Masculinidades e fatores sociais de risco para a saúde: um retrato nacional

O objetivo geral deste artigo é analisar os fatores de ordem social que influenciam a saúde dos homens portugueses, em particular os comportamentos que se associam à construção das masculinidades. Para satisfazer o objetivo da pesquisa proceder‑se‑á à análise de alguns indicadores estatísticos produzidos por fontes oficiais, de natureza amostral ou administrativa, como o INE ou o EUROSTAT. O modelo de masculinidade que emerge da análise dos indicadores nacionais apresentados remete para um ideário de género muito associado a estilos de vida e desempenho de profissões com impacto negativo na esperança média de vida dos homens portugueses. Tendo como referência as mulheres, destaca‑se no caso dos homens: maior taxa de acidentes de viação; consumo de álcool e tabaco mais acentuado e prematuro; mais mortes associadas ao consumo de drogas; mais mortes autoprovocadas intencionalmente; maior incidência da SIDA; maior número de acidentes de trabalho. ABSTRACT - The purpose of this article is to analyze the social factors that influence the health of Portuguese men, namely the behaviors that can be associated to the construction of masculinities. To satisfy this objective we will analyze some statistical indicators produced by official sources like INE or EUROSTAT. The model of masculinity that emerges from national indicators analysis is associated to behaviors and consumptions with a negative impact in Portuguese men health and life expectancy. In this article we highlight some of these behaviors: biggest rate of transport accidents; larger and early alcohol and tobacco consumption; more deaths associated to the consumption of drugs; more auto provoked deaths; bigger AIDS incidence; more occupational accidents.

Risk assessment in occupational exposure to formaldehyde: differences between anatomy and pathology laboratories and formaldehyde-resins production

Formaldehyde (CH2O), the most simple and reactive of all aldehydes, is colorless, and readily polymerizing gas at normal temperature. The most extensive use is in production of resins and has an important application as a disinfectant and preservative, reason why relevant workplace exposure may also occur in pathology and anatomy laboratories and in mortuaries. A study was carried out in Portugal, in a formaldehyde production resins factory and in 10 pathology and anatomy laboratories. It was applied a risk assessment methodology based on Queensland University proposal that permitted to perform risk assessment for each activity developed in a work station. This methodology was applied in 83 different activities developed in the laboratories and in 18 activities of the factory. Also, Micronucleus Test was performed in lymphocytes from 30 factory workers and 50 laboratories workers.

Maternal neurotic symptoms and infants' risk of developing persistent diarrhoea

A previously calculated predictive model for health risk selects infants who suffer 4-5 times more morbidity than their unselected peers. Preliminary results suggested that this risk is related to maternal neurotic symptomatology. To evaluate this hypothesis, 52 consecutive mothers whose infants had a positive predictive score (Group 1) and 52 in whom this was negative (Group 2) were evaluated by means of Goldberg's General Health Questionnaire (GHQ - 30). A total of 41.9% and 20.5% of the mothers in Groups 1 and 2, respectively, scored above 11 points in GHQ-30, established as the cut off point. It is concluded that among poor urban families in Santiago mothers of infants with high risk of persistent diarrhoea have increased frequency of detectable neurotic symptoms. New programs aimed at this type of infant should include psychological support for their mothers.

Risk assessment of exposure to multiple mycotoxins in food

Moulds may produce a diversity of toxins such as aflatoxins, ochratoxins, trichothecenes, zearalenone, fumonisins and others. Although toxicological, environmental and epidemiological studies have addressed the problem of these toxins one by one, more than one mycotoxin are found usually in the same contaminated food. Risk assessment for humans potentially exposed to multimycotoxins suffers very much from the lack of adequate food consumption data. Furthermore, for a given mycotoxin, synergism and antagonism with other mycotoxins, found in the same food commodities, are not taken into account. Aflatoxin B1 and ochratoxin A belong to the most frequently occurring mycotoxins. This has repeatedly been demonstrated, however, normally, the risk resulting from their simultaneous occurrence is not considered. A descriptive study was developed to monitor air fungal contamination in one hospital food unit.

Poverty levels and children's health status: study of risk factors in an urban population of low socioeconomic level

To test the hypothesis that the low socioeconomic population living is shanty towns in Porto Alegre presents different levels of poverty which are reflected on its health status, a cross-sectional study was designed involving 477 families living in Vila Grande Cruzeiro, Porto Alegre, Brazil. The poverty level of the families was measured by using an instrument specifically designed for poor urban populations. Children from families living in extreme poverty (poorest quartile) were found to have higher infant mortality rate, lower birth weights, more hospitalizations, and higher malnutrition rates, in addition to belonging to more numerous families. Thus, the shanty town population of Porto Alegre is not homogeneous, and priority should be given to the more vulnerable subgroups.
