Psychosocial risks prevention: Perspectives from Portuguese SMEs

Introduction: This paper presents the Portuguese results from the first phase of the PPPSER project, which has a qualitative nature. Micro, small and medium enterprises (SMEs) represent 99.9% of the Portuguese business setting. According to national sources, there are 1,167,811 SMEs in Portugal, with a combined turnover of 220 billion euros. Therefore, the main goal of this phase was to gather data from relevant SMEs stakeholders about what they perceived as psychosocial risks, their main causes and consequences, the general level of awareness about the issue, the main obstacles to prevention and intervention and specific actions developed considering those risks.info:eu-repo/semantics/publishedVersio

Multiple bosses, incivility and health: the positive effect of role clarity

Nowadays, the complexity of organisational settings increases the demands workers need to cope with. An example of this complexity is showed by Arlington and Baker (2000) who introduced the concept of multiple accountabilities (MA) which refers to having to report to several individuals at the same or/and at higher levels of the hierarchy. MA might generate conflicting expectations between supervisors, being a stressor for people involved and a prejudicial factor for workers’ well-being. When such stressor is experienced during a long time, it might be a source of burnout. Moreover, drawing from the Social Power Theory (French & Raven, 1959), MA might be a source of Workplace Incivility (WI; Andersson and Pearson, 1999), which refers to low-intensity deviant behaviors characterized by perpetrators’ ambiguous intent to harm the victim. WI might act as an instrument to reaffirm power (Cortina, 2001) and people who have MA might be more exposed to such negative dynamics, with a detrimental effect for their well-being. However, and according to the Job Demands-Resources model (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001), some resources, such as role clarity (RC), might moderate the negative effect of MA. Clarify roles might empower workers helping them to manage with multiple reports. The goal of this research is to analyse the effect of MA on burnout through WI. Moreover, we are going to assess if RC moderates the effect of MA on both WI and burnout. A total of 249 people employed at a multinational organisation completed an online questionnaire. 52.6% of the sample were women; the age of 44.2% of workers ranges between 40 and 49 years old. Controlling for age, sex and education, the macro PROCESS, model 8, was used to test the moderated mediation of MA on burnout mediated by WI, with the paths between MA and WI, and MA and burnout moderated by RC. Results showed a significant interaction between MA and RC (b= -.25, t(242)= -2.87, p<.01) predicting WI. The relationship between MA and WI is significant at all levels of the moderator but its magnitude diminishes at higher levels of RC. Moreover, a significant interaction between MA and RC exists predicting burnout (b= .18, t(241)= 2.52, p<.05). Results show that higher levels of MA always predict higher levels of burnout, but when MA is low, lower levels of RC enhance burnout. Data for the index of moderated mediation demonstrated that the bootstrapped 95% confidence interval for burnout ranges from -.109 to -.016, indicating a conditional significant indirect effect. The confidence interval for mediation through WI excluded zero at any level of the moderator. This study has several implications. At a theoretical level, we extend the current knowledge about MA; moreover, we demonstrate that MA is an antecedent of WI and burnout. We also demonstrated the positive effect of RC. At practical level, organisations should be aware of RC positive effect when demands, such as MA, are present. Organisations should improve such resources, clarifying expectations and fostering open communication between people involved.info:eu-repo/semantics/acceptedVersio

Application of Fourier transform infrared spectroscopy and orthogonal projections to latent structures/partial least squares regression for estimation of procyanidins average degree of polymerisation

Fourier transform infrared (FTIR) spectroscopy has being emphasised as a widespread technique in the quick assess of food components. In this work, procyanidins were extracted with methanol and acetone/water from the seeds of white and red grape varieties. A fractionation by graded methanol/chloroform precipitations allowed to obtain 26 samples that were characterised using thiolysis as pre-treatment followed by HPLC-UV and MS detection. The average degree of polymerisation (DPn) of the procyanidins in the samples ranged from 2 to 11 flavan-3-ol residues. FTIR spectroscopy within the wavenumbers region of 1800-700 cm(-1) allowed to build a partial least squares (PLS1) regression model with 8 latent variables (LVs) for the estimation of the DPn, giving a RMSECV of 11.7%, with a R(2) of 0.91 and a RMSEP of 2.58. The application of orthogonal projection to latent structures (O-PLS1) clarifies the interpretation of the regression model vectors. Moreover, the O-PLS procedure has removed 88% of non-correlated variations with the DPn, allowing to relate the increase of the absorbance peaks at 1203 and 1099 cm(-1) with the increase of the DPn due to the higher proportion of substitutions in the aromatic ring of the polymerised procyanidin molecules.The authors gratefully acknowledge Pedro Vasco (Universidade de Aveiro) and Eng.

Crescimento inicial de porta enxertos cítricos em substratos alternativos.

A produção de mudas cítricas de qualidade, passa pela produção em ambiente protegido, que apesar de aumentar o preço das mudas, qualifica-as com padrão fitossanitário. Entretanto, o que limita a adoção desse sistema de forma irrestrita no país é o alto custo da estufa e do substrato comercial. Para tanto, estudos que visem à elaboração de substratos alternativos, de fácil e constante disponibilidade a um baixo custo, tornam-se essenciais para dar suporte à modernização na produção de mudas, principalmente pelos pequenos viveiristas da região Nordeste e especialmente do Estado da Paraíba

Caracterização de acessos de aceroleira com base em descritores do fruto.

A acerola (Malpighia emarginata L.) que tem como centro de origem a região das Antilhas,é uma frutífera tropical de grande importância econômica e social devido ao seu alto teor de vitamina C, sendo também rica em outros nutrientes como carotenóides, tiamina, riboflavina e niacina. Apesar disso, poucos estudos têm sido realizados para ampliar o conhecimento sobre essa espécie, seja na área de coleta, conservação, caracterização e avaliação de germoplasma, seja no melhoramento genético visando o desenvolvimento de cultivares ou de práticas adequadas de cultivo e manejo (SALLA et al., 2002)
