Texto completoResumen
For a long time, scientists assumed that newborns have a severely limited sense of pain (if any). However, this assumption is wrong and led to a “start of the exit” from piglet surgical castration. Some of the currently discussed or already implemented alternatives such as general or local anaesthesia during surgical castration raise additional welfare concerns as well as legal problems and/or are hardly applicable. The favoured long-term, welfare-friendly “gold standard” is to raise entire male pigs (EM). However, this may also impose certain welfare problems under the current conventional housing and management conditions. The specific types of behaviour displayed by EM such as mounting and aggressive behaviours but also increased exploration, which are partially linked to sexual maturation, increase the risk for injuries. The current status of knowledge (scientific literature and farmer experiences) on housing of EM suggests that environmental enrichment, space, group-stability, social constellation, feeding (diet and feeder space), health and climate control are critical factors to be considered for future housing systems. From an animal welfare point of view, an intermediate variant to be favoured to reduce problematic behaviour could be to slaughter EM before reaching puberty or to immunize boars early on to suppress testicular function. Immunization against endogenous GnRH can reduce EM-specific problems after the 2nd vaccination.

To improve students' critical thinking skills, this study used online PBL (Problem-Based Learning) on learning Natural Science in the field of Biology. This research was conducted in pre-experimental research design with the subjects of 4th semester students in study program of PGMI (Teacher Education of Madrasah Ibtidaiyah). The results of the analysis showed that the improvement of critical thinking skill of female students is better than male groups. Based on the results of the hypothesis testing obtained from the data showed that the N_Gain critical thinking skill of male and female students were greater than α (sig. 0.051 ˃ (α) 0.05.), therefore H0 was accepted and H1 was rejected. That is, there is no difference in the improvement of critical thinking skill between male and female students. When it came from the indicators of critical thinking, the N-Gain score for all indicators of the female group was better than that of the male one. Also, for students’ independence, the average percentage of student responses in all aspects showed that they were in a Good category. The average percentage of student responses on the planning aspect was 73.65% in a Good category. The process aspect of student independent learning had the highest score among the three aspects, which was 75.73% or in the Good category, and the Learning Evaluation Aspect has the lowest score among the three aspects, which was 66.53% and was in a Good category.

The paper focused on the analysis of the gender factors under the developing of a marketing program to promote green goods. With the purpose to identify the scientific schools on this theme, the bibliometric analysis was conducted. In 2013 year and 2019 year, there was a significant increase in the number of publications which focused on the investigation on green marketing issues. Such trends could be explained by the growing level of interest of the world community in environmental issues. The findings allowed concluding that green marketing is considered by scientists in linking with such scientific areas as health economics, social development, economic development. The scientific community studied the gender and age parameters as key factors in the effective implementation of green marketing. In order to determine the role of gender and age factors in decision-making on the purchase of environmental goods, the survey of 176 students from Sumy State University (Ukraine) was conducted. The findings confirmed that women were more aware of environmental products than men, and 84.1% of women prefer to buy environmental products. It was determined that the most popular eco bags are shoppers – 54.5% among respondents, in second place – garbage sorting (49.4% among respondents), in third place – the rejection of plastic (48.3% among respondents). It was found that 77.8% of respondents are looking for eco-products in the category of food. Male respondents of all age are most looking for eco-goods in the category of household goods (55 respondents). Male respondents do not follow modern eco-trends and do not pay much attention to environmental labelling. Women, on the other hand, are more aware of environmental issues and often support eco-trends. The generalized results showed that one of the factors that reduce the effectiveness of green marketing was the low level of awareness of students on the nature and importance of eco-products. It was found that gender should be considered during the selection of communications channels with students and green marketing tools for the promotion of environmental products.

ABSTRACTOlder men are becoming more visible in care-giving research but there are still few studies that focus expressly on the extent to which care-giving has made positive contributions to their life and has been rewarding. Drawing on data from in-depth personal interviews, this Portuguese study analyses the positive statements in the personal descriptions of the care-giving experience of 53 elderly men who were caring for chronically-ill wives. It also explores the differences between the positive references made by the men who were caring for a wife who had dementia and those made by men whose wives had physical impairments. Using open coding and content analysis, positive aspects were identified in 32 of the 53 care-giving situations. The most prevalent themes were ‘satisfaction’ and ‘perceived social honour’. The findings show that positive returns from the caring experience and role were strongly associated with previous good marital relationships and the husband's good self-rated health, and manifested in both specific coping strategies and global and situational meaning-making processes. The study demonstrates that much more can be learnt about the positive dimensions of care in older men's lives, and that such understanding can inform and strengthen formal and therapeutic support.

Texto completoResumen
Environmental factors can shape reproductive investment strategies and influence the variance in male mating success. Environmental effects on extrapair paternity have traditionally been ascribed to aspects of the social environment, such as breeding density and synchrony. However, social factors are often confounded with habitat quality and are challenging to disentangle. We used both natural variation in habitat quality and a food supplementation experiment to separate the effects of food availability—one key aspect of habitat quality—on extrapair paternity (EPP) and reproductive success in the black-throated blue warbler, Setophaga caerulescens . High natural food availability was associated with higher within-pair paternity (WPP) and fledging two broods late in the breeding season, but lower EPP. Food-supplemented males had higher WPP leading to higher reproductive success relative to controls, and when in low-quality habitat, food-supplemented males were more likely to fledge two broods but less likely to gain EPP. Our results demonstrate that food availability affects trade-offs in reproductive activities. When food constraints are reduced, males invest in WPP at the expense of EPP. These findings imply that environmental change could alter how individuals allocate their resources and affect the selective environment that drives variation in male mating success.

Texto completoResumen
The Dublin Principles recognize the role that women play in water resources management. The South African Minister of Water Affairs, Prof. Kader Asmal, coined a new expression by referring to the “feminization of water”. The article explores some of the ramifications of this and shows that the two aspects are not necessarily the same thing. Feminization does not necessarily mean bringing more women into management processes as it is often depicted. This is the quantitative aspect that is often referred to by male managers and it has been given a negative implication as a result. The more important issue is the qualitative aspect that involves processes such as stakeholder participation, viewing alternatives before a decision is made and accountability.

Male sex work (MSW) research has been generally limited to the examination of “social problems.” Although there have been studies on occupational aspects, pointed examinations of the occupational environment, detailing the contemporary nature of the field, are rare. Research on nuances of the occupational context of MSW, providing insight on the rapidly changing face of the field, is wanting. Semistructured interviews were conducted with 20 escorts in Brisbane, Australia. This study explored job success, indicating that success in the field was well articulated, possibly highlighting that male independent escorting is becoming a professionalized occupation, with a shift away from current stigmatized understandings.

"Assessment of the Efficacy of a Constructed Wetland to Reduce or Remove Wastewater Effluent Estrogenicity and Toxicity Using Biomarkers in Male Fathead Minnows (Pimephales Promelas Rafinesque, 1820)". Thesis, University of North Texas, 2000. https://digital.library.unt.edu/ark:/67531/metadc2676/.
Texto completoResumen
Vitellogenin in Pimephales promelas was used to assess estrogenicity of a local municipal effluent. Vitellogenin induction in male P. promelas increased in frequency and magnitude with increased exposure duration and was greater ("=0.05) than controls after 2 and 3 weeks of exposure. The level of vitellogenesis induced by effluent exposure was high compared to similar studies. A spring season evaluation followed. Biomarkers in P. promelas were used to assess the efficacy of a treatment wetland to remove toxicity and estrogenicity in final treated wastewater effluent. Comparisons were made with an effluent dominated stream and laboratory controls. Vitellogenin, GSIs (gonado-somatic indices), HSIs (hepato-somatic indices) and secondary sexual characteristics were biomarkers used in P. promelas models to assess aqueous estrogenicity. Biological indicators used to assess general fish health included hematocrit and condition factors. The estrogenic nature of the effluent was screened, concurrent with fish exposure, with GC/MS analysis for target estrogenic compounds including: 17-b estradiol, estrone, ethynylestradiol, Bisphenol A, nonylphenolic compounds, phthalates, and DDT. Plasma vitellogenin measured in P. promelas was significantly elevated (p < 0.0001) at the inflow site of the wetland and stream sites. GSIs for these exposures were less (a=0.001) at the wetland inflow site. At wetland sites closest to the inflow, secondary sexual charateristics, tubercle numbers and fat pad thickness, were less (a=0.0001). Hematocrit and condition factors were less (a=0.001) at sites closer to the wetland inflow. Seasonal variation was examined by repeating the effluent characterization in summer. Additionally, summer testing included exposure to an effluent dilution series. Fish condition heavily influenced interpretation of the results. Pre-acclimation exposure to spawning stresses may have altered many of the biological markers measured. Results are discussed relative to fish health and pre-exposure environment. Toxicity assessed with P. promelas biomarkers was compared with Ceriodaphnia dubia and Vibrio fischeri toxicty tests on this effluent. Biomarkers of fish health were somewhat less sensitive than C. dubia test endpoints, but more sensitive than V. fisheri.

Texto completoResumen
This study's aim was to investigate the strength of contextual aspects' influences on environmentally ethical behaviour (EEB). A survey method with a selfadministered questionnaire was used and a cross-section of the Muslim male population of New Zealand was taken. The qualitative interviews and email questionnaires were also utilised to further explain the survey results. The linear regression analyses show correlations between contextual aspects (i.e., social, religious, economic, political, and demographic) and EEB (pre-cycling, re-use and recycling). Results indicate that the contextual aspects are influential on EEB in many ways and degrees. A model describing the relationship was developed. The economic aspect statistically significantly related to EEB the strongest. The qualitative interview and email questionnaire data support the findings of the survey. The relationship was positive, meaning that the more the consumers were influenced by the economic aspect to behave in an environmentally ethical way, the more they were likely to perform EEB. Compared to the economic aspect, white collar workers, number of household occupant, work involvement with the environment, type of house, and age had a weaker statistically significant relationship with EEB. The relationships were positive, meaning that the better the consumers' occupation (i.e., white collar workers), the more household member they had (i.e., 4 and above), the higher their level of work involvement with the environment, and the better their dwelling (i.e., bungalow or semi-detached houses), the more they were likely to perform EEB. However, the relationship between age and EEB was negative, meaning that the younger the consumers the more they were likely to perform EEB. However, the results of this study, from both the survey and the interview methods, indicate that demographic characteristics were not as important as the contextual aspects, particularly the economic aspect, in understanding consumers' EEB. This study shows that the economic aspect was very important in understanding consumers' EEB compared to the other contextual aspects even the political aspect was statistically significantly related to EEB via the economic aspect. Thus, the economic aspect should be used optimally by public and private sector managers to promote EEB.

Kosuta, Sonja A. "Movement of copper from in-ground root control fabrics". Thesis, McGill University, 1998. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=21582.
Texto completoResumen
Copper hydroxide-treated surfaces are commonly used to control roots in horticultural production systems, although the particulars of Cu movement from the treated surface are largely unknown. The rate and temporal pattern of Cu mobility from in-ground Cu-treated growing baskets, and the fate of this Cu, was studied. In a field experiment involving Acer platanoides, an alternative Cu formulation consisting of Cu metal powder was determined to move slightly more slowly from the basket fabric than Cu(OH)2 over the first season while providing adequate root control. Addition of Glomus intraradices inoculum to the basket system increased the mobility of Cu metal and had no effect on Cu(OH) 2. This suggests that VAM fungi can actively solubilize Cu metal. These results also confirm that the chemistry of the Cu, possibly in addition to the chemistry of the resin, determines Cu movement from the treated surface. The fate of Cu from in-ground baskets planted with Acer jinnala was elucidated in a second field experiment. After one field season, the majority of Cu initially on the basket fabric had been deposited in the soil both in- and outside the basket. While Cu recovered in leachate represented only a tiny fraction of basket Cu, the concentration of Cu in leachate exceeded acceptable limits in the majority of samples. This indicates that the use of Cu(OH) 2-treated baskets in the field may have a negative impact on groundwater quality.

Texto completoResumen
La recherche réalisée dans le cadre de notre thèse vise à étudier les conditions de la construction de l’énonciation de l’homosexualité masculine en proposant une analyse comparative des époques récentes. Ce qui nous intéresse alors, ce sont ainsi les supports de communication (espaces médiatiques et technologies numériques) et les formes de prise de parole. Notre thèse s’organise autour de trois parties. La première partie consiste à mettre en avant le contexte et les caractéristiques de l’énonciation de l’homosexualité. Nous proposons de revenir sur les travaux de Michel Foucault (au travers de son ouvrage La volonté de savoir) afin d’étudier la mise en discours du sexe et ainsi la construction des sexualités. Cela nous amène ainsi à identifier, à travers les époques, les variations de l’énonciation allant d’une logique du secret à une logique revendicative (voire subversive), mais également à étudier la place et les différentes conceptions du coming out. Dans une deuxième partie, nous mettons en avant les différents héritages des formes d’énonciation. Pour cela, nous évoquons les différentes manières de représenter l’homosexualité masculine au cinéma, à la télévision et dans les web séries, à travers une approche linéaire et généalogique des années 1930 à aujourd’hui. Puis, nous revenons également sur les pratiques de la drague homosexuelle selon les lieux ouverts et fermés ; ce qui nous amène alors à nous interroger sur l’existence d’une libération des formes expressives. Enfin, à partir de l’analyse de l’application mobile Grindr, nous proposons dans une troisième et dernière partie, d’identifier les différentes figures du dragueur et ses itinérances à l’heure de la géolocalisation. Nous abordons plus précisément le statut et le rapport à l’image, l’identification des différents types de regards qui s’organisent dans l’application, et les enjeux et les conséquences dans le cadre de l’énonciation de l’homosexualitéThe research conducted as part of our thesis aims at looking into the construction of the utterance of male homosexuality putting forward comparative analysis of recent times. Our concern is communication medium (media environment and digital technologies) as well as the different forms of speaking. Our thesis is organized around three parts. The first part consists in highlighting the context and the characteristics about telling homosexuality. We will suggest to revisit Michel Foucault’s work (through his work La volonté de savoir – The will to know) in order to study the implementation of the discourse about sex and then the construction of sexualities. It is also a question of identifying the variations of the self-ascription from the logic of secret to a protest or even subversive form of logic through different times, with the evocation of the place and the different aspects of “coming out”. In a second part, we will explain the different legacies of the ways to express homosexuality. We will then mention the different ways to represent male homosexuality in films, television and in web series through a linear and genealogical basis from the 1930’s until today. We will next review the practice of cruising according to open or closed areas: this will lead us to question the existence of the liberation of expressive forms. Finally, in a third and last part, we will put forward, from the mobile phone application Grindr, the identification of the different features of the cruiser as well as his roaming in a geo-tracking world. We will discuss more precisely the status and the relationship to image, the identification of the different types of views organized through the applications and the stakes and consequences as part of the utterance of homosexuality

Texto completoResumen
Dans ce travail de thèse, on s'intéresse é l'emploi de techniques de traitement de signal de systèmes de communication MIMO (Multiple Input Multiple Output) pour des applications aux réseaux de capteurs sans fil. Les contraintes énergétiques de cette classe de réseau font appel à des topologies particulières et le réseau peut être perçu comme étant un ensemble de grappes de nœuds capteurs. Ceci ouvre la porte à des techniques avancées de communication de type MIMO. Dans un premier temps, les différents aspects caractérisant les réseaux de capteurs sans fil sont introduits. Puis, les efforts engagés pour optimiser la conservation de l'énergie dans ces réseaux sont résumés. Les concepts de base de systèmes MIMOs sont abordés dans le deuxième chapitre et l'exploration par voie numérique de différentes pistes de la technologie MIMO sont exposées. Nous nous intéressons à des techniques de diversité de polarisation dans le cadre de milieux de communication riches en diffuseurs. Par la suite, des méthodes de type beamforming sont proposées pour la localisation dans les réseaux de capteurs sans fil. Le nouvel algorithme de localisation est présenté et les performances sont évaluées. Nous identifions la configuration pour la communication inter-grappes qui permet pour les meilleurs compromis entre énergie et efficacité spectrale dans les réseaux de capteurs sans fil. Finalement, nous envisageons la technique de sélection de nœuds capteurs afin de réduire la consommation de l'énergie dans le réseau de capteur sans filThe aim of this work is to study from a signal processing point of view the use of MIMO (Multiple Input Multiple Output) communication systems for algorithms dedicated to wireless sensor networks. We investigate energy-constrained wireless sensor networks and we focus on cluster topology of the network. This topology permits for the use of MIMO communication system model. First, we review different aspects that characterize the wireless sensor network. Then, we introduce the existing strategies for energy conservation in the network. The basic concepts of MIMO systems are presented in the second chapter and numerical results are provided for evaluating the performances of MIMO techniques. Of particular interest, polarization diversity over rich scattering environment is studied. Thereafter, beamforming approach is proposed for the development of an original localization algorithm in wireless sensor network. The novel algorithm is described and performances are evaluated by simulation. We determine the optimal system configuration between a pair of clusters that permits for the highest capacity to energy ratio in the fourth chapter. The final chapter is devoted to sensor nodes selection in wireless sensor network. The aim of using such technique is to make energy conservation in the network

AbstractNasopharyngeal cancer (NPC) is an uncommon cancer. According to the Global Cancer Observatory, of the 129,000 new diagnoses in 2018, 85% has been made in the Asiatic population. In males the annual age adjusted rate of incidence (per 100,000) dramatically varied between 8 in South-Eastern Asia and <1 in Europe. In Europe (period of diagnosis 1999–2007), the annual incidence rate varied between 0.7 (South of Europe) and 0.2 (North of Europe). Incidence is three time higher in men than women. Elderly are more affected than young people. Five-year survival, from European population based cancer registries was 49% (period 1999–2007), survival was better in younger than in older patients (73% vs. 31%), prognosis was more favorable in women than men (54% vs. 47%). Geographical variation of survival was reported, with poor 5-year in the Eastern European countries (36%).Incidence and population based survival are crucial for public health and planning clinical study. Lifestyle and environmental factors are responsible of the decreasing trend of incidence in quite all the world countries.Being one of the rare diseases, NPC need to be centralized for diagnosis and treatment. In Europe, the European Joint Action of Rare Cancers and the European Reference Network for rare disease will play an important role to make progress and reduce geographical disparities.

Abstract Sweden has been hailed for its recent success in increasing the number of female directors, scriptwriters and producers. Published reports, panel discussions and a vast number of press conferences on the pressing matter of gender equality within the industry together with a 5050 quota have all put the Swedish film industry—and its CEO Anna Serner—on the map. However, the last couple of years has disclosed several scandals regarding sexism and discrimination in the Swedish film industry—just as in other national film industries. This paper sets out to discuss how female film workers (e.g., directors, actors and producers) understand and negotiate their experiences of male dominance within their work context. Based on a series of interviews with women working in Swedish film from the early 1960s until today, we analyze similarities and differences in experiences as well as how these experiences are explained by the interviewees. Their stories are analyzed by using feminist institutional theory to understand how policy, funding schemes and other institutional aspects are intertwined with their experiences. The paper sets out to analyze three themes: (1) comments and suggestions during production and post-production regarding female protagonists; (2) experience of gender trouble in the process of fundraising; and (3) strategies used by the interviewed filmmakers to produce a more women-friendly environment during productions.

AbstractAnthropology’s focus on the holistic dimensions of the human condition, its interest in understanding humankind’s cultural variation wherever it occurs, and its sensitivity to both similarities and differences, while never losing sight of the powers of politics, ideologies, economies, and ecologies, provide a solid foundation for the exploration and understanding of environmental communication. This book tries to make sense of how an anthropological perspective can further our understanding of the diversity of environmental communication and the different ways people—verbally and non-verbally—communicate about and with their surrounding environments. An important aspect lies in the discussion of the communicative prospects for sustainability, seeking to bring anthropology into more theoretically and empirically productive engagement with the study of environmental communication.

Texto completoResumen
<p>Strong seismic shaking is recognized as the direct cause of structural failures. In many cases, however, the factor that initiates the structural damage is ground failure or ground displacement. This chapter deals with the identification of all geotechnical related structural failures. Surface fault rupture has been a well-acknowledged cause of failures of structures built across or near the fault, which are increasing in frequency as the man-made environment constantly expands to new areas. Seismically induced rockfalls, landslides and slope failures have also been associ-ated with major disasters with an increasing frequency in some cases due to an expanding popu-lation, which encroach on areas with landslide risk or in other cases as result of the destruction of the natural environment (vegetation and water routes), which have protected these slopes in the past. Foundation damage may be a result of failure of shallow foundations or piles. In addition, although liquefaction and ground settlement are technically part of foundation failures, they are usually treated as separate, special cases. Retaining wall structures, usually considered as simple systems, may display a complex behaviour, which can be related to extensive seismic failures. Finally, not taking into account soil–structure interaction (SSI) may have a detrimental effect on the dynamic response of structures. Although SSI may never be the direct cause of a structural failure, it has proven to be, in several cases, the underlying reason for the analysis misconception that led to the failure.</p>

It has been well documented that the ageing, male dominated profile of the workforce in the UK nuclear industry will not support the forecasted nuclear renaissance. Based upon the aspects of age, gender and level of education, there is an existing shortfall in available knowledgeable resource to undertake and manage the extensive new build, operational and decommissioning programmes. The 2005 Nuclear Employers Survey advised the industry to recruit and train more: • young and qualified people. • experienced and qualified people from outside the industry. The future for the UK nuclear industry lies with people in their 20s and 30s. It is essential that not just technical talent but also managerial talent be identified early and that they are nourished and allowed to flourish.

Texto completoResumen
Ergonomic conditions and workers comfort during L-shaped desk usage in an occupational environment has not been extensively studied in the literature. Thus, the objective of this study was to describe how workers have spontaneously positioned their VDUs on L-shaped desks and to analyze related ergonomic aspects of the workstation and the worker’s comfort. Thirteen females and one male VDU worker were observed by a physiotherapist ergonomist during their working time and their comfort was evaluated when using the desk on an 11 point scale. Eight workers positioned the VDU on the concave edge of the desk and seven of them reported high levels of comfort. The main reason for workers positively evaluating this desk was the extra space provided by the desk, which increases the working area in relation to the traditional ones. Workers who evaluated their comfort as lower than 7 (n=6) usually maintained the VDU either on the straight part of the desk or on an intermediate area between the concave and the straight part of the desk (n=5). Observations performed during work revealed the need for environmental, organizational and ergonomic rearrangements of the workstation aiming to prevent musculoskeletal disorders among workers who use L-shaped desks.

Texto completoResumen
The article deals with theoretical and legal issues related to the mechanisms of national security. The study shows that in order to ensure national security, it is necessary to take into account its constituent elements. One such element is energy security. Ensuring energy security should be implemented at the local, regional and Federal levels, taking into account the constitutional rights of citizens to a favorable environment, the prevention of environmental and man-made disasters, the rational use of natural resources. The author proposes to apply new approaches to the regulation of this type of relations, taking into account the systematization of normative legal acts in force in the Russian Federation, for the most effective solution of environmental and legal problems of energy security in Russia.

In order for companies to attain greater reductions in environmental burdens during manufacturing operations, they need to consider environmental aspects during their initial product development stages. This places an additional burden on designers and process engineers who already need to meet multiple objectives within tight constraints. Consequently, environmental aspects are rarely considered in their decision making process. Thus, if environmentally conscious decisions are to be made, the utilization of existing information must be maximized. In response to this problem we propose an approach for storing and reusing environmentally-related process information of similar component process plans via environmental process model templates. These templates will contain standard environmental information and models associated with manufacturing operations and thus should effectively support environmentally conscious decisions in component process planning and eventually design. We illustrate how the templates can be developed for a gear process planning example.

This study aims to explore environmental toxicity in the workplace. The study highlights essential aspects of the toxicity environment, such as the definitions, causes, and impacts. The breach of contract in an organization is considered an important aspect that affects the employees’ mood and attitude in the workplace. The failure of duties and responsibilities of an organization may greatly significantly affect employees psychologically. The violation of company-employees agreement plays a significant role in changing employees' views and feelings. The research study has shown that the best intervention measures in the workplace help reduce adverse effects of thetoxic environment in an organization. The study suggests that intervention skills such as team- building, cultural diversification helps in reducing social behavior such as harassment, discrimination, and bullying, thus reducing toxicity harm. Several graphs have been used to explain the different types of stress triggered by various aspects such as working nature, workplace relationships, and threats. The organization's code of ethics helps guide the employees and management to make reasonable judgments, thus eliminating unethical issues. The study highlighted some crucial recommendations which when embraced, may enhance a suitable workplace, thus minimizing workplace toxicity.

Texto completoResumen
Product and process engineering design is a complex problem which relies on multiple fields, and while many design aid tools exist they rarely take into account more than a single field or aspect at a time. This implies that a few tools have to used for a single project, making the engineer, or designer, juggle among them or favouring a single aspect. Many existing environmental assessment tools on the market only focus on environmental aspects, which are extremely important in today’s impact conscious context but are not enough to make viable products and processes. Moreover the tools often require precise data which is only known during the late stages of design when it is too late to make any significant changes. The aim of the current work is to further develop and test a multi-domain modelling framework, for the early stages of product and process design, which primarily focuses on environmental assessment but also takes into account economic aspects and can be expanded to further fields, such as risk. The two bases for the proposed framework are exergy, a measure of useful work that can be, unlike energy, both created and destroyed, and dimensional analysis, a widely used tool in engineering to model problems through dimensional homogeneity. The environmental and economic assessments proposed by the tool are illustrated on the case of insulation of the cabin on a passenger ferry and the environmental results are compared to those from two existing methodologies, Eco-Indicator and Cumulative Exergy Demand.

Air pollution is the most serious environmental problem facing most industrial cities in the world and in China. The World Health Organization measured the concentration of sulfur dioxide, nitrogen dioxide and total suspended particulate matter in 272 cities in 53 countries around the world, listing the ten most severely polluted cities in the world. The spatial and temporal distribu-tion of air pollutants depends on various factors such as the meteorological field, the source of emissions, the complex bottom surface of the site, the interplay of physical and chemical processes, and has strong non-linear characteristics [5]. Air quality forecasting is commonly used in the field of statistical forecasting methods, according to long-term monitoring data, the creation of a statisti-cal forecasting model, the model is simple, easy to operate business, but no solid physical founda-tion, and another numerical forecasting model based on atmospheric physics and material transfer model although the physical foundation is solid, comprehensive forecast results, but the forecast results are not reliable. Already in the 1950s, the system of meteorology of air pollution was gradu-ally formed, the box model, the Gaussian model, the Lagrange model, the Euler model, the dense gas model and other five types of models appeared. The first Gaussian model allows one to obtain a diffusion model of a local small-scale space and make predictions, then, based on the Gaussian model of the study, a modified model is obtained for other reliefs and weather conditions. There-fore, the modeling accuracy and applicable conditions are difficult to cope with the needs of large-scale complex meteorological conditions of air quality models.

The issue of replacing natural leather with leather substitutes is increasingly common in the leather goods industry. In this paper, it was addressed the issue of ensuring the physiological and comfort parameters when wearing leather substitute shoes. The aim of the paper is to analyze how the sanogenetic indicators influence the hygienic properties of footwear products starting from the porosity of the materials subjected to experimental determinations. Poromeric skin substitutes will be used, which allow the passage of water vapor and air. Both types of leather substitutes for shoe uppers and some types of textile materials for linings will be subjected to laboratory analysis, using the pycnometric method. In conclusion, the values obtained for porosity fall between 47 and 58%, limits also provided by the specialized literature. It is noted that the porosity values of leather substitutes are close to those of chrome-tanned leather, so as a result, the value of leather substitutes use will increase (they have sanogenetic properties similar to natural leather). Currently, leather substitutes are used more and more in the manufacture of footwear products, because they maintain a thermal transfer balance between the foot and the surrounding environment, favoring the elimination of moisture produced by the foot when wearing the footwear in the outdoor environment.

Texto completoResumen
In the last few years, there has been a significant increase in the demand for Uranium as historical inventories have been consumed and new reactor orders are being placed. Numerous mineralized properties around the world are being evaluated for Uranium recovery and new mining / milling projects are being evaluated and developed. Ore bodies which are considered uneconomical to mine by conventional methods such as tunneling or open pits, can be candidates for non-conventional recovery techniques, involving considerably less capital expenditure. Technologies such as Uranium in situ leaching in situ recovery (ISL / ISR), have enabled commercial scale mining and milling of relatively small ore pockets of lower grade, and may make a significant contribution to overall world wide uranium supplies over the next ten years. Commercial size solution mining production facilities have operated in the US since 1975. Solution mining involves the pumping of groundwater, fortified with oxidizing and complexing agents into an ore body, solubilizing the uranium in situ, and then pumping the solutions to the surface where they are fed to a processing plant. Processing involves ion exchange and may also include precipitation, drying or calcining and packaging operations depending on facility specifics. This paper presents an overview of the ISR process and the health physics monitoring programs developed at a number of commercial scale ISL / ISR Uranium recovery and production facillities as a result of the radiological character of these processes. Although many radiological aspects of the process are similar to that of conventional mills, conventional-type tailings as such are not generated. However, liquid and solid by product materials may be generated and impounded. The quantity and radiological character of these by products are related to facility specifics. Some special monitoring considerations are presented which are required due to the manner in which Radon gas is evolved in the process and the unique aspects of controlling solution flow patterns underground. An overview of the major aspects of the health physics and radiation protection programs that were developed at these facilities are discussed and contrasted to circumstances of the current generation and state of the art of Uranium ISR technologies and facilities.

Volume I focuses specifically on the achievement results, detailing Australia’s results within the international context, and presents results for the Australian jurisdictions, and for the different demographic groups within Australia, including male and female students. This report, Volume II, presents the results from the contextual questionnaires, and examines the contexts in which learning and achievement occur, including home, school, and classroom contexts, as well as student attitudes. Each chapter focuses on different indicators that cover the school community, the school learning environment, mathematics and science teacher characteristics, mathematics and science classroom learning environments, and students’ attitudes and beliefs. Together, the different indicators of student and school life illustrate some of the many key aspects that make up the school experience.

Texto completoResumen
Climate resilience is the ability to anticipate, prepare for, and respond to hazardous events, trends, or disturbances related to climate (C2ES, 2022). Mitigation focuses on reducing the human impacts contributing to climate change (Burton, 2007, cited in Rousell & Cutter-Mackenzie-Knowles, 2020). Adaptation is about increasing people’s adaptive capacity, reducing the vulnerability of communities and managing risks (Anderson, 2012). Anderson further defines adaptation as not just being able to adapt from one stable climate to another but having the skills to adapt to uncertainty and make informed decisions in a changing environment. While ‘climate change’ is the term used throughout these briefs, it should be read as a shorthand for a more inclusive approach, which also captures associated environmental degradation. The Intergovernmental Panel on Climate Change (IPCC) warned, in their latest report, that global surface temperatures will continue to increase until 2050 (IPCC, 2021, p. 17). This will take place regardless of human intervention to reduce greenhouse gas emissions. The report also warns that the traditional technocratic approaches are insufficient to tackle the challenge of climate change, and that greater focus on the structural causes is needed. High- and upper-middle-income countries have been persistently shown to be the biggest contributors to the global carbon dioxide emissions, with lower income countries facing the most disruptive climate hazards, with Africa countries particularly vulnerable (CDP, 2020; IPCC, 2021). The vulnerability of low-income contexts exacerbates this risk, as there is often insufficient infrastructure and resources to ensure resilience to climate hazards (IPCC, 2021). For decades, advocates of climate change education have been highlighting the potential of education to help mitigate against climate change, and support adaptation efforts. However, implementation has been patchy, with inconsistent approaches and a lack of evidence to help determine the most effective way forward.This paper is divided into three sections, drawing together evidence on the key aspects of system reform,green and resilient infrastructure and Curriculum, pedagogy, assessment and teacher development.

Freedom of Religious Belief and People with Disabilities: A Case Study of People with Disabilities from Religious Minorities in Chennai, India.

Texto completoResumen
India has a unique and complex religious history, with faith and spirituality playing an important role in everyday life. Hinduism is the majority religion, and there are many minority religions. India also has a complicated class system and entrenched gender structures. Disability is another important identity. Many of these factors determine people’s experiences of social inclusion or exclusion. This paper explores how these intersecting identities influence the experience of inequality and marginalisation, with a particular focus on people with disabilities from minority religious backgrounds. A participatory qualitative methodology was employed in Chennai, to gather case studies that describe in-depth experiences of participants. Our findings show that many factors that make up a person’s identity intersect in India and impact how someone is included or excluded by society, with religious minority affiliation, caste, disability status, and gender all having the potential to add layers of marginalisation. These various identity factors, and how individuals and society react to them, impact on how people experience their social existence. Identity factors that form the basis for discrimination can be either visible or invisible, and discrimination may be explicit or implicit. Despite various legal and human rights frameworks at the national and international level that aim to prevent marginalisation, discrimination based on these factors is still prevalent in India. While some tokenistic interventions and schemes are in place to overcome marginalisation, such initiatives often only focus on one factor of identity, rather than considering intersecting factors. People with disabilities continue to experience exclusion in all aspects of their lives. Discrimination can exist both between, as well as within, religious communities, and is particularly prevalent in formal environments. Caste-based exclusion continues to be a major problem in India. The current socioeconomic environment and political climate can be seen to perpetuate marginalisation based on these factors. However, when people are included in society, regardless of belonging to a religious minority, having a disability, or being a certain caste, the impact on their life can be very positive.

Texto completoResumen
This paper shares our experience of developing an EU-level baseline for research and innovation (R&I) in food systems, in support of the European Commission’s transformation agenda, with specific reference to the Food 2030 initiative. Food 2030 relates to the EU’s mission-oriented approach to R&I, viewing it within the context of a dynamic food system with multiple dependencies and many different actors. This approach aligns with a growing recognition that, in order to achieve transformational change, the interactions and interdependencies of all components within a given system and its relationship to other systems must be considered. In a transformative R&I system, innovation itself is no longer the endgoal but is viewed as an enabler to solve societal and environmental challenges (the end-objective). Linking such broader outcomes back to specific R&I inputs is not a straightforward endeavour. Furthermore, the inter- and transdisciplinary nature of a systems approach, as well as the nature of systems thinking itself, make it hard to define evaluative boundaries. Traditional public sector approaches to supporting R&I do not align well with such an approach, with implications for evaluating R&I policy. The paper focuses specifically on the novel aspects of the EU’s approach to framing food systems R&I and the evaluation challenges this presents, as well as how we have worked to mitigate these.

Texto completoResumen
There are many aspects of the transportation industry that can be focused on, but the lack of resiliency is one of the most urgent. Enhancing resiliency and creative problem-solving is essential to the industry’s growth and survival. But it cannot happen without building a more diverse workforce. Women still make up a small fraction of transportation workers, and African American and Hispanic employees are even less represented. These disparities are increasingly pronounced in many senior positions, particularly in STEM fields. Meanwhile, the public transportation industry is experiencing a severe and worsening workforce shortage and many agencies have reported substantial difficulty recruiting, retaining, and developing skilled workers. Considering the transit industry’s existing diversity and inclusion toolkits and guidelines, this project emphasizes lessons from in-depth interviews with leaders from 18 transit agencies across the country. The interviews illuminate the existing challenges and creative solutions around transit workforce diversity and inclusion. From the interviews, we discovered: 1) the critical factors that impact the current level of diversity and career mobility within transit agencies; 2) how diversity efforts help explore resources and provide opportunities for effective and robust employee engagement; and 3) the significance of evaluation systems in creating a more transparent recruitment process that initiates structural shifts, resulting in better recruiting. Moving towards inclusive and equitable workforce environments is a healing process that starts with understanding these gaps. We call this effort Healing the Workforce through Diversification.

Texto completoResumen
The Green Climate Fund (GCF), established in 2010 at the 16th Conference of Parties (COP16) under the United Nations Framework Convention on Climate Change (UNFCCC), is now the world’s largest climate financing institution. It has a current investment portfolio of 43 approved projects totaling around US$2 billion, and has 48 Accredited Entities (AEs) to support implementation, including UN agencies, banks, NGOs, and private companies. Through its investments, the GCF aims to achieve a paradigm shift in developing countries, toward low-emissions development and climate resilience. GCF investments must indicate whether and how they could impact Indigenous Peoples, local communities, and women who are most at risk from the adverse effects of climate change (e.g. via environmental and social management plans). These goals, however, are currently being challenged by inadequacies in the Fund’s policies and frameworks. GCF safeguards fail to recognize the critical contributions of rural peoples to the maintenance of ecosystem services that are essential to international climate and development objectives, and to offer adequate protection for their land and resource rights. Drawing on international standards and GCF policy documents, this report traces the adequacy and implementation effectiveness of the Fund’s current institutional frameworks across a representative sample of approved projects. Noting critical gaps in nearly every aspect of the Fund’s operational modalities and project approval processes, the report calls on the GCF to take progressive steps to make Indigenous Peoples’ and local communities’ rights a key part of its climate actions going forward.

Wright, Kirsten. Collecting Plant Phenology Data In Imperiled Oregon White Oak Ecosystems: Analysis and Recommendations for Metro. Portland State University, marzo de 2020. http://dx.doi.org/10.15760/mem.64.
Texto completoResumen
Highly imperiled Oregon white oak ecosystems are a regional conservation priority of numerous organizations, including Oregon Metro, a regional government serving over one million people in the Portland area. Previously dominant systems in the Pacific Northwest, upland prairie and oak woodlands are now experiencing significant threat, with only 2% remaining in the Willamette Valley in small fragments (Hulse et al. 2002). These fragments are of high conservation value because of the rich biodiversity they support, including rare and endemic species, such as Delphinium leucophaeum (Oregon Department of Agriculture, 2020). Since 2010, Metro scientists and volunteers have collected phenology data on approximately 140 species of forbs and graminoids in regional oak prairie and woodlands. Phenology is the study of life-stage events in plants and animals, such as budbreak and senescence in flowering plants, and widely acknowledged as a sensitive indicator of environmental change (Parmesan 2007). Indeed, shifts in plant phenology have been observed over the last few decades as a result of climate change (Parmesan 2006). In oak systems, these changes have profound implications for plant community composition and diversity, as well as trophic interactions and general ecosystem function (Willis 2008). While the original intent of Metro’s phenology data-collection was to track long-term phenology trends, limitations in data collection methods have made such analysis difficult. Rather, these data are currently used to inform seasonal management decisions on Metro properties, such as when to collect seed for propagation and when to spray herbicide to control invasive species. Metro is now interested in fine-tuning their data-collection methods to better capture long-term phenology trends to guide future conservation strategies. Addressing the regional and global conservation issues of our time will require unprecedented collaboration. Phenology data collected on Metro properties is not only an important asset for Metro’s conservation plan, but holds potential to support broader research on a larger scale. As a leader in urban conservation, Metro is poised to make a meaningful scientific contribution by sharing phenology data with regional and national organizations. Data-sharing will benefit the common goal of conservation and create avenues for collaboration with other scientists and conservation practitioners (Rosemartin 2013). In order to support Metro’s ongoing conservation efforts in Oregon white oak systems, I have implemented a three-part master’s project. Part one of the project examines Metro’s previously collected phenology data, providing descriptive statistics and assessing the strengths and weaknesses of the methods by which the data were collected. Part two makes recommendations for improving future phenology data-collection methods, and includes recommendations for datasharing with regional and national organizations. Part three is a collection of scientific vouchers documenting key plant species in varying phases of phenology for Metro’s teaching herbarium. The purpose of these vouchers is to provide a visual tool for Metro staff and volunteers who rely on plant identification to carry out aspects of their job in plant conservation. Each component of this project addresses specific aspects of Metro’s conservation program, from day-to-day management concerns to long-term scientific inquiry.

Texto completoResumen
The long-term goals of our research are to understand the regulation of sclerotial development and pathogenicity in S. sclerotiorum. The focus in this project is on the elucidation of the signaling events and environmental cues involved in the regulation of these processes, utilizing and continuously developing tools our research groups have established and/or adapted for analysis of S. sclerotiorum. Our stated specific objectives were to: 1. Follow activities and function of S. sclerotiorumPKA. 2. Identify and functionally evaluate effectors of the S. sclerotiorumERK-likeMAPK signaling pathway. 3. Perform structural and functional analysis of genes whose expression is altered under conditions affecting either PKA and/or MAPK. As can be seen below, we have not only met most of the listed goals, but have also expanded our research. We have been working both together and in parallel in order to advance our goals. We have jointly shown how an ERK-likeMAPK is required sclerotia formation. We have analyzed, in parallel, the involvement of PKA in sclerotiogenesis and, interestingly, have reached some overlapping results but each group has provided a slightly different interpretation to the picture obtained. It will be interesting to see how this aspect of the analysis progresses, as we jointly tackle the yet unresloved issues. We have also made progress on the analysis of ser/thr phosphatases (specifically – calcineurin, which has been reported to interact with PKA) and PP2A in S. sclerotiorum as well as the S. sclerotiorum rasgene, which we have cloned and shown induces SMK1, the ERK-like kinase responsible for sclerotia formation. In addition to the time and efforts invested towards reaching the specific goals mentioned, both PIs are actively involved in a major international effort to sequence and annotate the entire S. sclerotiorum genome. Though time consuming (and perhaps requiring divergence of some time and resources from the original workplan), we have given this topic a very high priority to this effort as the long term implications of the success of this venture are enormous.

Texto completoResumen
The main recommendations of the panel report can be summarised under five key headings: HUMANITY The Panel recommends recognition that research in this field should be geared towards the development of critical understandings of self and society in the modern world. Archaeological research into the modern past should be ambitious in seeking to contribute to understanding of the major social, economic and environmental developments through which the modern world came into being. Modern-world archaeology can add significantly to knowledge of Scotland’s historical relationships with the rest of the British Isles, Europe and the wider world. Archaeology offers a new perspective on what it has meant to be a modern person and a member of modern society, inhabiting a modern world. MATERIALITY The Panel recommends approaches to research which focus on the materiality of the recent past (i.e. the character of relationships between people and their material world). Archaeology’s contribution to understandings of the modern world lies in its ability to situate, humanise and contextualise broader historical developments. Archaeological research can provide new insights into the modern past by investigating historical trends not as abstract phenomena but as changes to real lives, affecting different localities in different ways. Archaeology can take a long-term perspective on major modern developments, researching their ‘prehistory’ (which often extends back into the Middle Ages) and their material legacy in the present. Archaeology can humanise and contextualise long-term processes and global connections by working outwards from individual life stories, developing biographies of individual artefacts and buildings and evidencing the reciprocity of people, things, places and landscapes. The modern person and modern social relationships were formed in and through material environments and, to understand modern humanity, it is crucial that we understand humanity’s material relationships in the modern world. PERSPECTIVE The Panel recommends the development, realisation and promotion of work which takes a critical perspective on the present from a deeper understanding of the recent past. Research into the modern past provides a critical perspective on the present, uncovering the origins of our current ways of life and of relating to each other and to the world around us. It is important that this relevance is acknowledged, understood, developed and mobilised to connect past, present and future. The material approach of archaeology can enhance understanding, challenge assumptions and develop new and alternative histories. Modern Scotland: Archaeology, the Modern past and the Modern present vi Archaeology can evidence varied experience of social, environmental and economic change in the past. It can consider questions of local distinctiveness and global homogeneity in complex and nuanced ways. It can reveal the hidden histories of those whose ways of life diverged from the historical mainstream. Archaeology can challenge simplistic, essentialist understandings of the recent Scottish past, providing insights into the historical character and interaction of Scottish, British and other identities and ideologies. COLLABORATION The Panel recommends the development of integrated and collaborative research practices. Perhaps above all other periods of the past, the modern past is a field of enquiry where there is great potential benefit in collaboration between different specialist sectors within archaeology, between different disciplines, between Scottish-based researchers and researchers elsewhere in the world and between professionals and the public. The Panel advocates the development of new ways of working involving integrated and collaborative investigation of the modern past. Extending beyond previous modes of inter-disciplinary practice, these new approaches should involve active engagement between different interests developing collaborative responses to common questions and problems. REFLECTION The Panel recommends that a reflexive approach is taken to the archaeology of the modern past, requiring research into the nature of academic, professional and public engagements with the modern past and the development of new reflexive modes of practice. Archaeology investigates the past but it does so from its position in the present. Research should develop a greater understanding of modern-period archaeology as a scholarly pursuit and social practice in the present. Research should provide insights into the ways in which the modern past is presented and represented in particular contexts. Work is required to better evidence popular understandings of and engagements with the modern past and to understand the politics of the recent past, particularly its material aspect. Research should seek to advance knowledge and understanding of the moral and ethical viewpoints held by professionals and members of the public in relation to the archaeology of the recent past. There is a need to critically review public engagement practices in modern-world archaeology and develop new modes of public-professional collaboration and to generate practices through which archaeology can make positive interventions in the world. And there is a need to embed processes of ethical reflection and beneficial action into archaeological practice relating to the modern past.

In Israel and in the U.S., Streptococcus iniae is responsible for considerable losses in various fish species. Poor understanding of its virulence factors and limited know-how-to of vaccine formulation and administration are the main reasons for the limited efficacy of vaccines. Our strategy was that in order to Improve control measures, both aspects should be equally addressed. Our proposal included the following objectives: (i) construction of host-pathogen interaction models; (ii) characterization of virulence factors and immunodominant antigens, with assessment of their relative importance in terms of protection and (iii) genetic identification of virulence factors and genes, with evaluation of the protective effect of recombinant proteins. We have shown that two different serotypes are involved. Their capsular polysaccharides (CPS) were characterized, and proved to play an important role in immune evasion and in other consequences of the infection. This is an innovative finding in fish bacteriology and resembles what, in other fields, has become apparent in the recent years: S. iniae alters surface antigens. By so doing, the pathogen escapes immune destruction. Immunological assays (agar-gel immunodiffusion and antibody titers) confirmed that only limited cross recognition between the two types occurs and that capsular polysaccharides are immunodominant. Vaccination with purified CPS (as an acellular vaccine) results in protection. In vitro and ex-vivo models have allowed us to unravel additional insights of the host-pathogen interactions. S. iniae 173 (type II) produced DNA fragmentation of TMB-8 cells characteristic of cellular necrosis; the same isolate also prevented the development of apoptosis in NCC. This was determined by finding reduced expression of phosphotidylserine (PS) on the outer membrane leaflet of NCC. NCC treated with this isolate had very high levels of cellular necrosis compared to all other isolates. This cellular pathology was confirmed by observing reduced DNA laddering in these same treated cells. Transmission EM also showed characteristic necrotic cellular changes in treated cells. To determine if the (in vitro) PCD/apoptosis protective effects of #173 correlated with any in vivo activity, tilapia were injected IV with #173 and #164 (an Israeli type I strain). Following injection, purified NCC were tested (in vitro) for cytotoxicity against HL-60 target cells. Four significant observations were made : (i) fish injected with #173 had 100-400% increased cytotoxicity compared to #164 (ii) in vivo activation occurred within 5 minutes of injection; (iii) activation occurred only within the peripheral blood compartment; and (iv) the isolate that protected NCC from apoptosis in vitro caused in vivo activation of cytotoxicity. The levels of in vivo cytotoxicity responses are associated with certain pathogens (pathogen associated molecular patterns/PAMP) and with the tissue of origin of NCC. NCC from different tissue (i.e. PBL, anterior kidney, spleen) exist in different states of differentiation. Random amplified polymorphic DNA (RAPD) analysis revealed the "adaptation" of the bacterium to the vaccinated environment, suggesting a "Darwinian-like" evolution of any bacterium. Due to the selective pressure which has occurred in the vaccinated environment, type II strains, able to evade the protective response elicited by the vaccine, have evolved from type I strains. The increased virulence through the appropriation of a novel antigenic composition conforms with pathogenic mechanisms described for other streptococci. Vaccine efficacy was improved: water-in-oil formulations were found effective in inducing protection that lasted for a period of (at least) 6 months. Protection was evaluated by functional tests - the protective effect, and immunological parameters - elicitation of T- and B-cells proliferation. Vaccinated fish were found to be resistant to the disease for (at least) six months; protection was accompanied by activation of the cellular and the humoral branches.
