Physiology and metabolic profile of Moringa olifera and Eucalyptus globulus plants subjected to climate changes

As alterações climáticas emergentes têm um grande impacto no crescimento e desenvolvimento de espécies florestais, nomeadamente em espécies de valor industrial e medicinal, como é o caso do eucalipto (Eucalyptus globulus) e da moringa (Moringa oleifera). Assim, é urgente conhecer as respostas fisiológicas e entender as variações que ocorrem nos perfis metabólicos de espécies vegetais. Neste trabalho, plantas jovens de Eucalyptus globulus foram expostas a radiação UVB (12kJ/m2) e foram avaliadas as respostas fisiológicas e o perfil metabólico, um e onze dias após a aplicação da radiação. A dose de UVB usada não afetou as reações fotoquímicas nem as trocas gasosas, contudo ao nível do metabolismo do carbono (AST e amido) e do conteúdo de pigmentos verificaram-se pequenas alterações (AST e pigmentos). Através da análise do perfil metabólico de E. globulus foram encontrados compostos voláteis e semi-voláteis pertencentes às famílias dos terpenos, sesquiterpenos e aldeídos. Em geral, os sesquiterpenos e os álcoois monoterpénicos apresentaram uma tendência para manter e, em alguns casos, diminuir com o stress, enquanto que o grupos dos aldeídos aumentou e os monoterpenos apresentaram um comportamento mais heterogéneo. O E. globulus mostrou ser uma espécie tolerante à aplicação da dose de UVB usada neste trabalho. Por outro lado, plantas jovens de M. oleifera foram expostas a défice hídrico (DH). Um grupo de plantas foi recolhido um dia após o final da exposição e o outro grupo após onze dias do final da exposição. Foi avaliado o perfil metabólico desta espécie através de GC/MS. Os dados cromatográficos indicaram que em condições de stress (DH(1) e DH(11)), as quantidades de compostos associados a vias primárias e secundárias de defesa (como os alcanos, álcoois, ácidos carboxílicos, esteróis, aminoácidos e açucares) sofreram algumas alterações. As plantas analisadas 11 dias após a remoção do stress mostraram maiores variações do perfil de metabolitos. No entanto, tanto um como onze dias após a remoção do stress, as plantas apresentaram a formação de novos rebentos. Apesar do perfil de metabolitos ter sofrido algumas alterações, por não se registarem casos de morte, conclui-se que as plantas de moringa mostraram ser tolerantes aos tratamentos aplicados.

Contributos para a construção de um perfil de competências do coordenador da educação especial

À medida que a supervisão, associada a lógicas de interação com a atividade docente e com outros intervenientes nos contextos educativos, adquiriu uma dimensão reflexiva e passou a ser entendida como instrumento de transformação do desenvolvimento humano e da qualidade do processo de ensino e aprendizagem na organização escolar inclusiva, tem vindo a conquistar o interesse de numerosos investigadores. Considerando que a intenção de oferecer uma escola de qualidade a todos e a cada um dos alunos (um dos princípios fundamentais da educação inclusiva), não está amplamente atingido, impõe-se uma nova atitude pessoal e institucional: um entendimento sistémico (envolvendo profissionais, alunos, pais e comunidade) sobre as respostas a oferecer aos alunos, capaz de atender às necessidades e especificidades de cada um, otimizando as suas oportunidades de aprendizagem e desenvolvimento. Na verdade, a intervenção na complexidade das diferentes situações-problema emergentes numa organização escola que se pretende inclusiva pode ser altamente potenciada se existir supervisão dos processos educacionais em curso. A especificidade do sistema de Educação Especial preconiza uma estrutura de coordenação e supervisão; uma estrutura capaz de viabilizar recursos e gerar dinâmicas de mediação à intervenção, bem como de acionar mecanismos de avaliação de processos e produtos, tornando-os consequentes ao nível das práticas e objetivando a aproximação a níveis superiores de funcionamento. Tendo como principal objetivo construir conhecimento sobre o perfil de competências profissionais do Coordenador da Educação Especial, com particular relevo na dimensão supervisiva inerente à respetiva ação, o estudo que se apresenta baseou-se numa abordagem de natureza mista para recolha e tratamento de dados de tipo quantitativo e qualitativo. Numa primeira fase, incluiu a aplicação dum inquérito por questionário a três grupos de informantes-chave: 105 professores de Educação Especial, 47 coordenadores da Educação Especial e 37 diretores de agrupamentos de escolas/escolas não agrupadas, do ensino público, da área de influência da Direção de Serviços da Região Centro, Direção-Geral dos Estabelecimentos Escolares. A segunda fase, em que se buscou vislumbrar insights passíveis de clarificar e aprofundar os dados recolhidos através dos inquéritos por questionário, compreendeu a realização de entrevistas a 10 especialistas em Educação Especial e/ou em Supervisão. Os dados apontam para um enquadramento organizacional /supervisivo em Educação Especial dissemelhante, podendo, todavia, identificar-se em comum, uma satisfatória ação liderante do Coordenador da Educação Especial, baseada em atividades de diálogo e reflexão, e respeitando princípios de colaboração e solidariedade. Há, no entanto, indicadores de que a prática deste coordenador se concentra bastante na gestão burocrática e administrativa do departamento/equipa, podendo isto explicar-se pelo facto de o Coordenador da Educação Especial servir mais de intermediário do que de interveniente entre órgãos de direção e gestão, nomeadamente, entre o diretor e o conselho pedagógico, e os docentes/profissionais do departamento/equipa. Os dados evidenciam também, a falta de formação dos coordenadores da Educação Especial em supervisão e salientam a importância do fator tempo para o eficaz exercício desse cargo, de modo a promover interações ricas e estimulantes, centradas nas reflexões sobre as práticas inclusivas. Podendo este coordenador contribuir de forma significativa para a dinamização e estímulo dos profissionais do agrupamento/escola, apoiando-os nos seus esforços e iniciativas para uma organização mais inclusiva, identificam-se alguns aspetos considerados determinantes no seu perfil de competências profissionais: experiência, conhecimentos, capacidades, valores e particularidades da personalidade.

Golf destinations' brand personality: the case of the Algarve

The purpose of this research is to develop and validate a measurement scale to assess golf destinations’ brand personality and therefore to perceive the destination personality of the Algarve as a golf destination. Based on literature review on human personality, brand personality, destination brand image and marketing scales validation procedures, an initial 36 unrepeated items were the base for a survey instrument. Those items were generated from the literature, from the results of individual interviews with experts in tourism and golf in the Algarve and from promotional texts in golf- related websites. After content validation, the items were allocated into categories of attributes by a panel of expert judges. A survey was then applied to a convenient sample of 600 golf players in the Algarve, and 545 (valid) questionnaires were analysed to refine the scale. Golf players assessed the components of the relational brand personality (functional, symbolic and experiential) as well as the Algarve as a golf destination. A taxonomy of brand personality was developed and tested in the Algarve as it is recognized as one of the world best golf destination. The developed taxonomy of brand personality was assessed in two ways: 1) through the overall perception of the Algarve as a golf destination and 2) through the perception of specific attributes of the destination grouped into three main categories (functional, symbolic and experiential). Therefore, two multi-dimensional brand personality models were estimated by using structural equation modelling. Findings of this study indicate that golf players ascribe personality characteristics to destinations. The brand personality of the Algarve is translated into three main dimensions enjoyableness, distinctiveness and friendliness when tourists/golf players reveal their overall perception of the destination. The brand personality of golf destination Algarve is reflected in the dimensions reliability, hospitality, uniqueness and attractiveness when tourists assess the components of the relational brand personality. Refined scales consisting of 10 and 12 items were finally derived meeting both reliability and validity requirements. This study does not replicate Aaker’s (1997) personality dimensions and very little parallelism can be drawn with Aaker’s (1997) brand personality scale since only three items from her scale were validated in both models: friendly and cheerful, (sincerity), reliable (competence). The same is verified concerning the ‘Big-five’. The human personality traits (HPT) validated to describe golf destinations personality are only four helpful, pleasant (agreeableness), relaxed (emotional stability), and innovative (intellect or openness). As far as destination image descriptors (DID) are concerned, the items appealing, relaxed and safe were validated, while traits suggested by the interviews and website promotional texts such as calm, natural, spectacular, unique, welcoming, and the best (destination-specific traits) appear to be appropriate to describe the personality of a golf destination. The results suggest that the overall perception of the Algarve´s brand personality is described by the dimensions enjoyableness, distinctiveness and friendliness. Moreover, the relational perspective revealed that the functional attributes of the destination are described by the dimension reliablility, while the symbolic attributes are described by the dimensions hospitablility and uniqueness and finally its experiential attributes are described by the dimension attractiveness. These results show that a golf destination´s brand personality should not just be based on good golf practices. Theoretical and practical implications are discussed in the context of destination brand personality.

Screening for success in a visual arts program.

Abstract: Little research has been directed towards determining means of predicting success in visual arts programs. Therefore, this study attemps to profile a typical successful student in a visual arts program, namely the Illustration & Design program at Dawson College. To this end, questionnaires, designed by the researcher, served to investigate the students' reasons for choosing the program as well as provide demographic data. In addition, students' personality types were investigated by means of the online Sternberg & Wagner Thinking Styles Inventory (SWTSI) questionnaire. Using the SPSS statistical software, an analysis was done to determine whether students who offer intrinsically motivated reasons for applying to the Illustration & Design program are those who also demonstrate greater academic success. Furthermore, grounding this study in Sternberg's theory of mental self governance, students' college grades were correlated to their personality type to determine if Type I personality types perform better academically than Type II or Type III (Zhang, 2005), The participants consisted of three cohorts (128 students form semester 1, 3 and 5) of the Illustration & Design program, as well as two comparison groups, one from the Fine Arts program (24 students), and another from the Business Administration program, a non-visual arts program at Dawson College (20 students).||Résumé: Les recherches portant sur l'identification de moyens qui permettent de prédire la réussite dans les programmes d'arts plastiques sont très rares. Par conséquent, cette étude tente de dresser le profil de l'élève type qui réussit dans un programme d'arts visuels, à savoir le programme Illustration & Design au Collège Dawson. À cette fin, des questionnaires conçus par le chercheur ont servi à déterminer les raisons pour lesquelles l'élève a choisi ce programme et ont permis de fournir des données démographiques. En outre, les étudiants ont été catégorisés par type de personnalité au moyen du questionnaire Sternberg & Wagner Thinking Styles Inventory (SWTSI). Grâce au logiciel statistique SPSS, une analyse a été effectuée afin de déterminer si les élèves dont la motivation comptait beaucoup dans leur choix du programme Illustration & Design étaient aussi ceux qui affichaient un taux de réussite plus élevé. En outre, en s'appuyant sur la Théorie d'autonomie de gestion mentale de Sternberg, cette étude avait pour but de corréler les résultats scolaires des élèves à leur personnalité afin de déterminer si les étudiants du Type de personnalité I avaient de meilleurs résultats scolaires que ceux de Type II et de Type III (Zhang, 2005). Les participants étaient composés de trois cohortes (128 étudiants des 1er, 3e et 5e semestres) du programme Illustration et Design ainsi que de deux groupes témoins, un groupe de 24 élèves du programme de Techniques de l'Administration, programme en dehors des arts visuels.

Are Premorbid Abnormal Personality Traits Associated with Behavioural and Psychological Symptoms in Dementia?

Objective: The study aims to investigate associations between behavioural and psychological symptoms of dementia (BPSD) and abnormal premorbid personality traits. Methods: Data were obtained from 217 patients with a diagnosis of probable Alzheimer’s disease. Behavioural and psychological symptoms of late-onset dementia were assessed with the Neuropsychiatric Inventory. Premorbid personality traits were assessed using the Standardised Assessment of Personality. Abnormal premorbid personality traits were categorised with Diagnostic and Statistical Manual of Mental Disorders fourth edition and International Statistical Classification of Diseases and Related Health Problems—10 diagnostic criteria for personality disorders. Results: Abnormal premorbid personality traits were associated with increased behavioural and psychological symptoms in dementia. Cluster A (solitary/paranoid) premorbid personality traits were associated with anxiety, depression and hallucinations. Cluster C (anxious/dependent) traits were associated with a syndrome of depression. Conclusions: The presence of Clusters A (solitary/paranoid) and C (anxious/dependent) abnormal premorbid personality traits seems to affect the expression of certain behavioural and psychological symptoms in dementia, depression in particular.

The relationship between dimensions of love, personality, and relationship length

The present study examined the associations among participant demographics, personality factors, love dimensions, and relationship length. In total, 16,030 participants completed an internet survey assessing Big Five personality factors, Sternberg’s three love dimensions (intimacy, passion, and commitment), and the length of time that they had been involved in a relationship. Results of structural equation modeling (SEM) showed that participant age was negatively associated with passion and positively associated with intimacy and commitment. In addition, the Big Five factor of Agreeableness was positively associated with all three love dimensions, whereas Conscientiousness was positively associated with intimacy and commitment. Finally, passion was negatively associated with relationship length, whereas commitment was positively correlated with relationship length. SEM results further showed that there were minor differences in these associations for women and men. Given the large sample size, our results reflect stable associations between personality factors and love dimensions. The present results may have important implications for relationship and marital counseling. Limitations of this study and further implications are discussed.

The personality attributes and leisure activities of the internet users: a Taiwanese case study

This study aims to examine the relationship between the personality attributes of Internet users and their leisure activities. A questionnaire survey was undertaken which revealed that most Internet users are single males aged between 21-30 belonging to the lower income groups, employed in information technology or related fields. The personality attributes of the sample showed a tendency towards a mixed locus control category. The survey indicated that the preferred leisure activities of this population group are reading, collecting and computer-based activities. However, ‘movement’ and collecting were the only leisure activities to show a significant correlation with the users’ personality attributes.

Examination of the factor structure of the Schizotypal Personality Questionnaire (SPQ) among British and Trinidadian adults

Much debate in schizotypal research has centred on the factor structure of the Schizotypal Personality Questionnaire (SPQ), with research variously showing higher-order dimensionality consisting of two to seven dimensions. In addition, cross-cultural support for the stability of those factors remains limited. Here, we examined the factor structure of the SPQ among British and Trinidadian adults. Participants from a White British sub-sample (n = 351) resident in the UK and from an African Caribbean sub-sample (n = 284) resident in Trinidad completed the SPQ. The higher-order factor structure of the SPQ was analysed through confirmatory factor analysis, followed by multiple-group analysis for the model of best-fit. Between-group differences for sex and ethnicity were investigated using multivariate analysis of variance in relation to the higher-order domains. The model of best-fit was the four-factor structure, which demonstrated measurement invariance across groups. Additionally, these data had an adequate fit for two alternative models: a) 3 factors and b) a modified 4-factor. The British sub-sample had significantly higher scores across all domains than the Trinidadian group, and men scored significantly higher on the disorganised domain than women. The four-factor structure received confirmatory support and, importantly, support for use with populations varying in ethnicity and culture.

Personality and performance on digit span tests in online and offline settings.

This paper describes two studies examining links between personality and performance on a cognitive test in online and laboratory settings. Study 1 was completed online. 345 participants passively recruited through a personality assessment website completed a Five Factor Model personality inventory derived from the International Personality Item Pool. They then completed an online text-based digit span test. This required participants to repeat increasingly longer strings of digits, either in the same order (forward) or in the opposite of the presentation order (reverse). Conventional digit span tasks ask participants to respond verbally; in this instance they responded by typing the digits. Agreeableness and Openness to Experience each had small but significant associations with forward and reverse digit span. In a second, laboratory based, study, 103 participants completed paper versions of the IPIP Five Factor inventory, the NEO-FFI, and a battery of cognitive tests including the WAIS 4 digit span test. In this instance, Agreeableness and Openness to Experience were not significantly correlated with digit span measures. Taken together, these studies suggest that personality characteristics may influence performance on an online cognitive test. This effect was not seen in an offline version of the study. The paper will consider potential implications for online testing, for equivalence of online and offline methods, and for links between personality and performance on this cognitive test.

Associations between Belief in Conspiracy Theories and the Maladaptive Personality Traits of the Personality Inventory for DSM-5

Conspiracy theories can be treated as both rational narratives of the world as well as outcomes of underlying maladaptive traits. Here, we examined associations between belief in conspiracy theories and individual differences in personality disorders. An Internet-based sample (N=259) completed measures of belief in conspiracy theories and the 25 facets of the Personality Inventory for DSM-5 (PID-5). Preliminary analyses showed no significant differences in belief in conspiracy theories across participant sex, ethnicity, and education. Regression analyses showed that the PID-5 facets of Unusual Beliefs and Experiences and, to a lesser extent, Suspiciousness, significantly predicted belief in conspiracy theories. These findings highlight a role for maladaptive personality traits in understanding belief in conspiracy theories, but require further investigation.

Personality, emotion, and mood in agent-based group decision making

Group decision making plays an important role in organizations, especially in the present-day economy that demands high-quality, yet quick decisions. Group decision-support systems (GDSSs) are interactive computer-based environments that support concerted, coordinated team efforts toward the completion of joint tasks. The need for collaborative work in organizations has led to the development of a set of general collaborative computer-supported technologies and specific GDSSs that support distributed groups (in time and space) in various domains. However, each person is unique and has different reactions to various arguments. Many times a disagreement arises because of the way we began arguing, not because of the content itself. Nevertheless, emotion, mood, and personality factors have not yet been addressed in GDSSs, despite how strongly they influence results. Our group’s previous work considered the roles that emotion and mood play in decision making. In this article, we reformulate these factors and include personality as well. Thus, this work incorporates personality, emotion, and mood in the negotiation process of an argumentbased group decision-making process. Our main goal in this work is to improve the negotiation process through argumentation using the affective characteristics of the involved participants. Each participant agent represents a group decision member. This representation lets us simulate people with different personalities. The discussion process between group members (agents) is made through the exchange of persuasive arguments. Although our multiagent architecture model4 includes two types of agents—the facilitator and the participant— this article focuses on the emotional, personality, and argumentation components of the participant agent.
