Speaking Out Online:The Benefits and Risks of Speaking About Sexual Violence for Young People

Speaking out about sexual violence has been a fundamental part of feminist politics since the 1970s. The practice of narrating experiences of violence, either publicly or to friends and family aims to combat the culture of silence and stigmatisation that surrounds sexual violence while also helping individuals to gain a sense of empowerment and connect with other survivors. However, speaking out also contains inherent risks, especially for young people. Survivors may meet with stigmatising or disbelieving responses, and they may lose control over who knows their story and the way in which it is told and retold.
These risks and benefits are altered, and potentially exacerbated, in an online environment. While social media may increase survivors’ ability to contact and connect with others with similar experiences it also makes it harder to control when and how their story is shared. The disjuncture between online and offline environments may also increase feelings of stigmatisation and isolation.
There is a need to explore the specific risks and benefits of speaking out online given both young people’s extensive use of social media for social interactions and the increasing tendency for support and educational services targeted at young people to make use of social media and online environments. This paper draws on literature and some preliminary research to consider both risks and benefits of speaking out online and to open a conversation about the creation of supportive spaces and mechanisms for young people to speak about sexual violence in online environments.

Health care professionals’ experience, understanding and perception of need of advanced cancer patients with cachexia and their families: The benefits of a dedicated clinic.

Background: Cachexia has been defined as an on-going loss of skeletal muscle mass that cannot be fully reversed by conventional nutritional support. It can be found in up to 80% of patients with advanced cancer and has profound psycho-social consequences for patients and their families. There is a paucity of studies examining the role and experience of healthcare professionals in relation to cachexia and existing studies suggest that professional staff have limited understanding and do not intervene effectively.
Aim: To identify barriers and facilitators to good practice in cachexia care in order to inform future developments in service provision.
Design: An exploratory qualitative study was conducted employing semi-structured interviews with a range of healthcare professionals recruited purposefully from an Australian hospital. Interviews were conducted in private rooms within the hospital.
Setting/participants: A range of healthcare professionals responsible for cancer care were recruited from a large Australian teaching hospital.
Results: Interviews were conducted with 8 healthcare professionals responsible for delivering cancer care. Four themes were identified: formal and informal education, knowledge and understanding, truth telling in cachexia and palliative care, and, a multi-disciplinary approach. Findings show how improved knowledge and understanding across a staff body can lead to improved staff confidence and a willingness to address cancer cachexia and its consequences with patients and their families.
Conclusion: Comparison with previous studies illustrates the importance of improving knowledge and understanding about cachexia and how this can contribute to staff having the skills and experience necessary to address cachexia and provide an improved care experience for patients and carers.

Potential health benefits of Artemisia gorgonum extracts

Relevância etnofarmacológica: Artemisia gorgonum (Asteraceae), conhecida como “losna ou lorna”, é usada em Cabo Verde na medicina tradicional para o tratamento de inflamações, febre e gastroenterites. Estudos recentes sugerem que artimetina, isolada a partir de Artemisa gorgonum, poderia ser usada para o tratamento da malária devido à sua atividade antiplasmodial. Objetivo do estudo: Avaliação in vitro da atividade anti-microbiana e sinergética dos extratos hidroetanol (70%) e metanol de A. gorgonum (EHAG e EMAG) em bactérias do trato urinário e uma espécie de fungo. A atividade antioxidante dos extratos de hidroetanol (70%), metanol, clorofórmio e clorofórmio-metanol (1:2), e o efeito protetor de EHAG contra lesões hepáticas em ratos induzidos com CCl4 também foram analisados. Material e métodos: A atividade antimicrobiana dos extratos de A. gorgonum foi testada in vitro contra sete estirpes de microrganismos, incluindo bactérias Gram-positivas, Gram-negativas e uma espécie de fungo. O método DAA (Decimal assay for additivity) foi determinado para atividade antibacteriana do EHAG contra Pseudomonas aeruginosa. O efeito antioxidante in vitro de vários extratos de A. gorgonum foi analisado pelo método DPPH. A lesão hepática foi induzida por injeção intrapeitoral do CCl4. Seguidamente, os ratos foram administrados oralmente com EHAG, diariamente, por um período de 7 dias. Resultados e Discussão: Foi observada atividade antibacteriana dos extratos de EHAG e EMAG contra todos os microrganismos usados neste estudo. O crescimento das estirpes de Escherichia coli e Pseudomonas aeruginosa foi o mais inibido por ambos os extratos, apresentando valores significativos, enquanto o crescimento das estirpes S. aureus e Klebsiella spp. foi o menos afetado. Candida albicans foi inibida fortemente pelo EMAG. As combinações de extrato hidroetanólico com antibióticos demonstraram atividade antibacteriana sinergética contra todos os patogénicos testados. Em contrapartida, a combinação de extrato metanólico com antibióticos permitiu observar efeitos antagónicos contra todas as bactérias, exceto Klebsiella spp. que apresentou atividade sinérgica. O EHAG e EMAG mostraram efeito significativo na eliminação do radical DPPH. A atividade hepatoprotetora foi observada em ratos previamente administrados com CCl4. Estes estudos evidenciam os potenciais benefícios de A. gorgonum.

Interactions of cetaceans with Spanish and Portuguese fisheries in Atlantic waters : costs, benefits and implications for management

With the aim to provide new insights into operational cetacean-fishery interactions in Atlantic waters, this thesis assesses interactions of cetaceans with Spanish and Portuguese fishing vessels operating in Iberian and South West Atlantic waters. Different opportunistic research methodologies were applied, including an interview survey with fishers (mainly skippers) and onboard observations by fisheries observers and skippers, to describe different types of interactions and to identify potential hotspots for cetacean-fishery interactions and the cetacean species most involved, and to quantify the extent and the consequences of these interactions in terms of benefits and costs for cetaceans and fisheries. In addition, the suitability of different mitigation strategies was evaluated and discussed. The results of this work indicate that cetaceans interact frequently with Spanish and Portuguese fishing vessels, sometimes in a beneficial way (e.g. cetaceans indicate fish schools in purse seine fisheries), but mostly with negative consequences (depredation on catch, gear damage and cetacean bycatch). Significant economic loss and high bycatch rates are, however, only reported for certain fisheries and associated with particular cetacean species. In Galician fisheries, substantial economic loss was reported as a result of bottlenose dolphins damaging artisanal coastal gillnets, while high catch loss may arise from common dolphins scattering fish in purse seine fisheries. High cetacean bycatch mortality arises in trawl fisheries, mainly of common dolphin and particularly during trawling in water depths below 350 m, and in coastal set gillnet fisheries (mainly common and bottlenose dolphins). In large-scale bottom-set longline fisheries in South West Atlantic waters, sperm whales may significantly reduce catch rates through depredation on catch. The high diversity of cetacean-fishery interactions observed in the study area indicates that case-specific management strategies are needed to reduce negative impacts on fisheries and cetaceans. Acoustic deterrent devices (pingers) may be used to prevent small cetaceans from approaching and getting entangled in purse seines and set gillnets, although possible problems include cetacean habituation to the pinger sounds, as well as negative side effects on non-target cetaceans (habitat exclusion) and fisheries target species (reduced catch rates). For sardine and horse mackerel, target species of Iberian Atlantic fisheries, no aversive reaction to pinger sounds was detected during tank experiments conducted in the scope of this thesis. Bycatch in trawls may be reduced by the implementation of time/area restrictions of fishing activity. In addition, the avoidance of fishing areas with high cetacean abundance combined with the minimization of fishery-specific sound cues that possibly attract cetaceans, may also help to decrease interactions. In large-scale bottom-set longline fisheries, cetacean depredation on catch may be reduced by covering hooked fish with net sleeves ("umbrellas") provided that catch rates are not negatively affected by this gear modification. Trap fishing, as an alternative fishing method to bottom-set gillnetting and longlining, also has the potential to reduce cetacean bycatch and depredation, given that fish catch rates are similar to the rates obtained by bottom-set gillnets and longlines, whereas cetacean by-catch is unlikely. Economic incentives, such as the eco-certification of dolphin-safe fishing methods, should be promoted in order to create an additional source of income for fishers negatively affected by interactions with cetaceans, which, in turn, may also increase fishers’ willingness to accept and adopt mitigation measures. Although the opportunistic sampling methods applied in this work have certain restrictions concerning their reliability and precision, the results are consistent with previous studies in the same area. Moreover, they allow for the active participation of fishers that can provide important complementary ecological and technical knowledge required for cetacean management and conservation.

Renaturing cities using a regionally-focused biodiversity-led multifunctional benefits approach to urban green infrastructure

If a ‘Renaturing of Cities’ strategy is to maximise the ecosystem service provision of urban green infrastructure (UGI), then detailed consideration of a habitat services, biodiversity-led approach and multifunctionality are necessary rather than relying on the assumed benefits of UGI per se. The paper presents preliminary data from three case studies, two in England and one in Germany, that explore how multifunctionality can be achieved, the stakeholders required, the usefulness of an experimental approach for demonstrating transformation, and how this can be fed back into policy. We argue that incorporating locally contextualised biodiversity-led UGI design into the planning and policy spheres contributes to the functioning and resilience of the city and provides the adaptability to respond to locally contextualised challenges, such as overheating, flooding, air pollution, health and wellbeing as well as biodiversity loss. Framing our research to encompass both the science of biodiversity-led UGI and co-developing methods for incorporating a strategic approach to implementation of biodiversity-led UGI by planners and developers addresses a gap in current knowledge and begins to address barriers to UGI implementation. By combining scientific with policy learning and defined urban environmental targets with community needs, our research to date has begun to demonstrate how nature-based solutions to building resilience and adaptive governance can be strategically incorporated within cities through UGI.

Estimation of unemployment rates in small areas of Portugal: a best linear unbiased prediction approach versus a hierarchical Bayes approach

The high level of unemployment is one of the major problems in most European countries nowadays. Hence, the demand for small area labor market statistics has rapidly increased over the past few years. The Labour Force Survey (LFS) conducted by the Portuguese Statistical Office is the main source of official statistics on the labour market at the macro level (e.g. NUTS2 and national level). However, the LFS was not designed to produce reliable statistics at the micro level (e.g. NUTS3, municipalities or further disaggregate level) due to small sample sizes. Consequently, traditional design-based estimators are not appropriate. A solution to this problem is to consider model-based estimators that "borrow information" from related areas or past samples by using auxiliary information. This paper reviews, under the model-based approach, Best Linear Unbiased Predictors and an estimator based on the posterior predictive distribution of a Hierarchical Bayesian model. The goal of this paper is to analyze the possibility to produce accurate unemployment rate statistics at micro level from the Portuguese LFS using these kinds of stimators. This paper discusses the advantages of using each approach and the viability of its implementation.

Replicating the Networking, Mentoring and Venture Creation Benefits of Entrepreneurship Centres on a Shoestring: A Student-centred Approach to Entrepreneurship Education and Venture Creation

As support for both university-level entrepreneurial education and the use of experiential learning methods to foster student entrepreneurs increases, so too have the number of university-established or affiliated entrepreneurship centers. The activity at the center of this study aimed to combine experiential learning methods with assets associated with entrepreneurship centers, including venture creation, networking, and mentoring. Students were invited to participate in a competition wherein they were guided through the business creation process and pitched their ideas to investor judges who chose the winner and provided capital start-up funding and consulting. This research puts forth that university faculty at institutions without entrepreneurship centers can organize experiences to provide the benefits of entrepreneurship centers. The study used interviews to find that many of the benefits of entrepreneurship centers were able to be replicated using this method. The project is outlined, outcomes are analyzed, and the results and lessons learned are discussed.
