Evaluating potential olive orchard sugar food sources for the olive fly parasitoid Psyttalia concolor

Olive fruit fly Bactrocera oleae (Rossi) (Diptera: Tephritidae) is a major olive pest in the Mediterranean basin where increasing insecticide resistance has enhanced damage and necessitates more reliance on other control strategies, such as biological control. Provision of floral resources has been reported to improve the effectiveness of natural enemies. Here, we tested the effect of six plant nectars and two honeydew sources on the survival of Psyttalia concolor (Szépligeti) (Hymenoptera: Braconidae), a parasitoid wasp used in the biological control of olive fruit fly. Our results showed a positive effect on survival associated with nectars of Anchusa azurea Mill., Rosmarinus officinalis L., Lavatera cretica L. and Calamintha nepeta (L.) Savi, while honeydew proved to be a valuable alternative food source. When offering flowers directly to insects, Anchusa azurea, Lavatera cretica, and Foeniculum vulgare L. were found to be the most beneficial species, indicating also that P. concolor feeds predominantly on shallow corollas.Research was financially supported by Fundação para a Ciência e Tecnologia (FCT), with partial funding from the European Fund for Regional Development, through the project PTDC/AGR‐AAM/100979/200

Gestão do processo de formulação,implementação e avaliação da política pública de cooperação para o desenvolvimento - análise na perspetiva da governança

Tese de Doutoramento em Administração Pública, especialidade de Administração e Políticas PúblicasO estudo pretende identificar os mecanismos de formulação, implementação e avaliação da política pública de cooperação para o desenvolvimento, segundo a perspetiva da governança, no período do XVII Governo Constitucional. Procura-se então perceber até que ponto os momentochave do processo da política pública (formulação, implementação e avaliação), ocorreram segundo a perspetiva de eficácia e eficiência e se foram tidos em conta, na perspetiva da governança, as dimensões que a suportam (World Bank, 1992; 1994), gestão do setor público, accountability, quadro jurídico para o desenvolvimento, e transparência e informação. Neste contexto compreende-se por governança o exercício governativo, quando este entende a participação da sociedade civil enquanto esta externa às instancias formais de decisão. Para o projeto de investigação qualitativo, recorreu-se à base teórica como suporte ao entendimento do exercício da governança no contexto da cooperação portuguesa, bem como à recolha documental, para além da realização de entrevistas e questionários que permitiram perceber o papel dos agentes com intervenção no processo de política pública, e qual o seu peso efetivo para a prossecução dos objetivos definidos. O sistema da cooperação portuguesa revela-se um sistema complexo, onde inúmeros fatores colaboram para a sua especificidade, requerendo do estado uma coordenação política e administrativa eficiente.This study aims at identifying the creation, implementation and evaluation mechanisms of the public development cooperation policies, according to the governance perspective of the 17th Constitutional Government. The purpose is to understand in what way the key-moments of the public policies process (creation, implementation and evaluation) took place, according to the efficiency and effectiveness principles and if, from a governance perspective, its supporting elements were considered (World Bank, 1992; 1994): public sector management, accountability, development legal framework and information transparency. In this context, governance should be read as the governmental practice which considers the participation of the civil society as an external element in what concerns the formal decisions instances. A theoretical basis was used to understand the governmental practice in the context of Portuguese cooperation, as far as the qualitative investigation project was concerned, as well documental investigation, interviews and questionnaires – all of which allowed for the recognition of the intervening agents in the public policy process and their effective weight on the achievement of the defined objectives. The Portuguese cooperation system is a complex one, in which a number of factors contribute to its specificities and thus requiring an efficient political and administrative coordination.N/

O caso da Universidade do Minho e da Universidade da Beira Interior

Numa sociedade sobrecarregada de informação visual, a existência de uma «identidade visual» actual e bem definida torna-se indispensável para que uma entidade possa captar a atenção do público, tanto a identidade como a imagem institucional têm uma importância crescente na gestão das entidades, nomeadamente das universidades. Dada a emergência da denominada «Sociedade do Conhecimento» e dos novos desafios que são impostos às universidades, estas entram num contexto de mercado onde são exigidos parâmetros de gestão equivalentes aos empresariais. Os componentes intangíveis como é o caso da identidade visual, que iremos analisar, tomam elevada importância. O presente estudo debruça-se sobre a identidade visual institucional, nomeadamente da Universidade do Minho e da Universidade da Beira Interior, e a necessidade desta ser redesenhada. A base de estudo é uma análise comparada da identidade visual da Universidade do Minho e da Universidade da Beira Interior, ambas foram identificadas através do brasão, a Universidade da Beira Interior ainda é, no entanto, a Universidade do Minho já renovou o seu símbolo de identificação. Assim, constitui propósito deste trabalho reflectir sobre as motivações que levam ao redesenho da identidade visual institucional, especialmente no caso das universidades do Minho e da Beira Interior.In a society bombarded with visual information, an up to date and well defined «visual identity» is indispensable in captivating the public’s interest in a company, the identity as much as the institutional image are of increasing importance in the management of entities, in particular for universities. Given the up and coming «Society of Knowledge» and the new challenges universities now face, these institutions must meet the demands of a market where management standards rival those of commercial companies. Intangible components, such as visual identity, which we propose to analyse, become of extreme importance. The present study focuses on the institutional visual identity, particularly the University of Minho and that of Beira Interior, and the need to readdress their designs. The study is based on a comparative analysis of the visual identity of the University of Minho and the University of Beira Interior, both recognisable through their respective coats of arms. The first has already adopted a different identification symbol, whereas the latter continues to show its original design. Therefore, the aim of this study is to reflect on the motivation behind the redesigning of the institutional visual identity, in particular of those of the Universities of Minho and Beira Interior

Mecanismos de coordenação e aprendizagem organizacional no processo de autoavaliação

Dissertação de mestrado, Educação (Área de Especialidade em Administração Educacional), 2022, Universidade de Lisboa, Instituto de EducaçãoO presente estudo aborda o processo de autoavaliação pelo prisma dos mecanismos de coordenação da ação, fazendo uma leitura cruzada destes com a autoavaliação e o desenvolvimento de aprendizagem organizacional. Com uma abordagem dupla e complementar, apresentam-se dois focos de análise: por um lado, com a lente dos mecanismos de coordenação da ação aborda-se o processo de autoavaliação e monitorização; por outro incide-se nas perceções sobre as repercussões do processo de autoavaliação e monitorização implementado, tendo em vista a aprendizagem organizacional, baseando-se nos mecanismos de coordenação da ação. Com o propósito de percecionar, num agrupamento de escolas da Área Metropolitana de Lisboa, em que medida os mecanismos de coordenação da ação foram determinantes e induziram a aprendizagem organizacional, no quadro dos processos de autoavaliação, considerou-se, como quadro temporal, o contexto pandémico, uma vez que este foi um período que impôs uma atuação reativa à emergência e tomada de decisão rápida pelas escolas. O quadro conceptual tem como pilares os conceitos de autoavaliação e monitorização, mecanismos de coordenação da ação e aprendizagem organizacional. Seguiu-se a metodologia qualitativa, tratando-se de um estudo naturalista inscrito no paradigma interpretativo. Como técnicas de recolha de dados, para além do inquérito por entrevista semiestruturada a dois intervenientes-chave, a diretora do agrupamento de escolas e a coordenadora da equipa de autoavaliação, recorreu-se à pesquisa arquivística. Tratando-se de uma investigação qualitativa, a técnica de tratamento de dados incidiu na análise de conteúdo, realizada através de indução analítica, num método comparativo constante. Concluiu-se que, no quadro da autoavaliação, os mecanismos de coordenação constituíram-se como determinantes e indutores de aprendizagem organizacional. Não se verificaram evidências de que tenham ocorrido os três níveis aprendizagem organizacional. Identificou-se a oportunidade de aprendizagem, do já implementado no período em estudo, para a construção de respostas futuras, às necessidades identificadas pelo agrupamento de escolas, que conciliem as duas vertentes: comunicação e articulação em proximidade física e comunicação e articulação no digital, enquanto complementares, suportando-se nos mecanismos de coordenação da ação.This study approaches the self-assessment process through the prism of coordination mechanisms, making a cross reading of these mechanisms with self-assessment and the development of organizational learning. With a dual and complementary approach, two focuses of analysis are presented: on the one hand, the process of self-assessment and monitoring is addressed through the coordination mechanisms; on the other hand, the focus is on the perceptions about the repercussions of the self-assessment and monitoring process implemented with a view to organizational learning, based on the coordination mechanisms. To have a perception, to what extent in a school cluster of the Lisbon Metropolitan Area, the coordination mechanisms were determinant and induced organizational learning in the context of the self-assessment processes, the pandemic context was considered as a time frame, since this was a period that imposed a reactive action to the emergency and quick decision-making by schools. The theoretical framework is based on the concepts of self-evaluation and monitoring, coordination mechanisms and organizational learning. A qualitative approach was used. The study is naturalistic, within an interpretive paradigm. To collect data, semi-structured interviews were made with two keyplayers, the principal of the school cluster and the coordinator of the self-evaluation team, we also chose to collect data using archival research. As a qualitative research, data treatment was content analysis, conducted through analytical induction, in a constant comparative method. We concluded that in the context of self-evaluation, the coordination mechanisms were key factors and inducers of organizational learning. No evidence was found that would allow us to perceive that, in the school, the three levels of organizational learning had occurred in this context. We identified the opportunity to learn from what was already implemented during the period under study, to build future responses to the needs identified by the school, which merge the two aspects: communication and articulation in physical proximity, communication, and articulation in digital proximity, as complementary, based on the mechanisms for action coordination

Polymorphism and Superconductivity in Bilayer Molecular Metals (CNB-EDT-TTF)4I3

Electrocrystallization from solutions of the dissymmetrical ET derivative cyanobenzene-ethylenedithio-tetrathiafulvalene (CNB-EDT-TTF) in the presence of triiodide I3 − affords two different polymorphs (β″ and κ) with the composition (CNB-EDT-TTF)4I3, both with a bilayer structure of the donors. These polymorphs differ in the packing patterns (β″- and κ-type) of the donor molecules in each layer, in both cases with bifurcated C−N···H interactions effectively coupling head-to-head donor molecules between layer pairs. Two β″ polymorphs can be obtained with different degrees of anionic ordering. In one disordered phase, β″d, with a smaller unit cell, the triiodide anions are disordered over two possible positions in a channel between the donor bilayers, while in the ordered phase, β″o, the triiodide anions occupy only one of those positions in this channel, leading to the doubling of the unit cell in the layer plane. These results for β″ phases contrast with the κ polymorph previously reported, for which weaker disorder of the triiodide anions, over two possible orientations with 94 and 6% occupation factors, was observed. While the β″ polymorphs remains metallic down to 1.5 K with a ρ300K/ρ4K resistivity ratio of 250, the κ polymorph presents a much smaller resistivity ratio in the range of 4−10 and superconductivity with an onset temperature of 3.5 K.This work was partially supported in Portugal by FCT under Contracts UID/Multi/04349/2013 and RECI/QEQ-QIN/ 0189/2012 and grants to S.O.

Hydroxycinnamic acids and their derivatives in broa, a traditional ethnic maize bread

This research was funded by EUROPEAN UNION'S SEVENTH FRAMEWORK PROGRAMME for research, technological development and demonstration under grant agreement number 245058, by FUNDACAO PARA A CIENCIA E TECNOLOGIA and PORTUGAL 2020 to the Portuguese Mass Spectrometry Network, grant number LISBOA-01-0145-FEDER-402-022125 and by FUNDACAO PARA A CIENCIA E TECNOLOGIA through IF/01337/2014 FCT Investigator contract (MCVP) and research unit GREEN-IT (UID/Multi/04551/2020).Maize is one of the most interesting dietary sources of hydroxycinnamic acids, widely known for their beneficial health effects, namely antioxidant properties. This work aims to identify hydroxycinnamic acids and their derivatives in broa, a Portuguese traditional ethnic maize bread, and corresponding maize flours. Soluble and insoluble phenolic fractions of diverse maize flours and corresponding broas were prepared and analysed by HPLC‐DAD‐MS/MS (high‐performance liquid chromatography coupled with diode array detector and tandem mass spectrometry). Besides free hydroxycinnamic acids, mainly ferulic and p‐coumaric acids, several structural isomers and stereoisomers of insoluble ferulic acid dehydrodimers (n = 18) and trimers (n = 11), were also identified. Hydroxycinnamic acid amides consisting of coumaroyl and feruloyl conjugates (n = 22) were present in both soluble and insoluble fractions of maize flours and breads, in different isomeric forms. A new compound was putatively identified as bis‐N,N′‐diferuloyl putrescine. Additionally, more complex and insoluble hydroxycinnamic acid amides, derived from ferulic acid dehydrodimers (n = 47) and trimers (n = 18), were also putatively identified for the first time, suggesting that hydroxycinnamic acid amides are also linked to maize cell walls. Since hydroxycinnamic derivatives were not only identified in maize flours, but also in broas, they can contribute to the antioxidant properties and beneficial health effects of maize‐based foods.publishersversionpublishe

DT-TTF Salts with [Cu(dcdmp)2]−: The Richness of Different Stoichiometries

(DT-TTF)[Cu(dcdmp)(2)] (1), (DT-TTF)(2)[Cu(dcdmp)(2)] (2), and (DT-TTF)(3)[Cu(dcdmp)(2)](2) (3) are three new charge transfer salts obtained by electrocrystallization of the donor DT-TTF (dithiophene-tetrathiafulvalene) with the diamagnetic copper complex [Cu(dcdmp)(2)](-) (dcdmp = 2,3-dicyano-5,6-dimercaptopyrazine). Compounds 1 and 3 crystallize in the triclinic system and consist of out-of-registry layers of mixed stacks of donor and acceptor molecules. (DT-TTF)(2)[Cu(dcdmp)(2)] presents a structure similar to the parent spin-ladder systems with donor stacks arranged in pairs; however, a magnetic spin-ladder behavior is not observed probably due to strong interactions between pairs. Compound 3, despite the mixed nature of the stacks, displays relatively high conductivity (7 S/cm) due to a one-dimensional network of interactions between donors.This work was supported by FCT (Portugal) through contracts PTDC/QEQ-SUP/1413/2012 and UID/Multi/04349/2013 and by DGI, Spain (CTQ2013-40480), the Generalitat de Catalunya (2014SGR0017), the CIBER de Bioingeniería, Biomateriales y Nanomedicina (CIBER-BBN), promoted by ISCIII, Spain.

Shedding light on the volatile composition of broa, a traditional portuguese maize bread

Funding Information: Funding: This research was funded by the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement number 245058, and by Fundação para a Ciência e Tecnologia through research unit GREEN-IT (UID/Multi/04551/2020).

Publisher Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland.In Portugal, maize has been used for centuries to produce an ethnic bread called broa, em-ploying traditional maize varieties, which are preferred by the consumers in detriment of commercial hybrids. In order to evaluate the maize volatiles that can influence consumers’ acceptance of broas, twelve broas were prepared from twelve maize varieties (eleven traditional and one commercial hybrid), following a traditional recipe. All maize flours and broas were analyzed by HS-SPME-GC-MS (headspace solid-phase microextraction) and broas were appraised by a consumer sensory panel. In addition, the major soluble phenolics and total carotenoids contents were quantitated in order to evaluate their influence as precursors or inhibitors of volatile compounds. Results showed that the major volatiles detected in maize flours and broas were aldehydes and alcohols, derived from lipid oxidation, and some ketones derived from carotenoids’ oxidation. Both lipid and carotenoids’ oxidation reactions appeared to be inhibited by soluble phenolics. In contrast, phenolic compounds appeared to increase browning reactions during bread making and, consequently, the production of pyranones. Traditional samples, especially those with higher contents in pyranones and lower contents in aldehydes, were preferred by the consumer sensory panel. These findings suggest that, without awareness, consumers prefer broas prepared from traditional maize flours with higher contents in health-promoting phenolic compounds, reinforcing the importance of preserving these valuable genetic resources.publishersversionpublishe

Cynara cardunculus: Use in Cheesemaking and Pharmaceutical Applications

Cynara cardunculus L. is the most widespread species of Cynara genus (f. Asteraceae). This herbaceous perennial plant is native to the Mediterranean region and invasive in other parts of the world, growing naturally in harsh habitat conditions. There are three subspecies: globe artichoke; cultivated cardoon and the progenitor of the two, the wild cardoon. The culture of Cynara cardunculus L. follows an annual growth cycle, emerging in autumn and harvesting in summer. Cynara cardunculus has been considered as a multi-purpose crop due to its relevant biochemical profiles. Inflorescences have been used as food, whereas leaves are a rich source of bioactive compounds. Consequently, larger plants without spines have been selected for technological purposes. Due to its high cellulose and hemicellulose content, the lignocellulosic fraction has been used as solid biofuel, biogas and bioethanol. Both pulp fibers production and seeds oil are suitable for biodiesel production. Over the centuries, the inflorescence pistils of Cynara cardunculus L. have been widely used for cheesemaking. The present chapter gives an overview of the Cynara cardunculus L. emphasizing recent knowledge regarding the use, conservation, preparation and application of Cynara cardunculus in ovine milk cheesemaking, as well as other biotechnological applications
