Community perceptions of collaborative processes for managing freshwater resources

Six of New Zealand’s 16 regional councils are trialling collaborative planning as a means of addressing complex challenges in freshwater management. Although some work has been undertaken to evaluate similarities and differences across those processes, the success or failure rests with the public’s acceptance of the processes and their outcomes. This is the first study to evaluate public perceptions of freshwater management in regions with collaborative processes. We surveyed 450 respondents in Hawke’s Bay, Northland, and Waikato, some of whom live in catchments in which collaborative processes are under way and some of whom do not. In addition to assessing awareness of the collaborative planning processes, the survey measured perceptions regarding the regional council’s management of freshwater resources, the extent of agreement regarding freshwater management among various interests, the fairness of freshwater management, and the extent to which respondents believe that their interests and concerns are included in freshwater management. We hypothesized that relative to respondents in parts of the region in which traditional processes are in places, respondents in catchments with collaborative management of freshwater resources would have more positive perceptions of management, agreement, fairness, and interests, even if there is low awareness that a collaborative planning process is under way. Survey results indicate that knowledge of collaborative processes is generally low and that living in catchments with collaborative processes does not impact respondents’ perceptions of management, agreement, fairness, or interests in Northland or Waikato. However, relative to Hawke’s Bay respondents living outside of the collaborative catchment, respondents living inside the collaborative catchment believe that the regional council’s freshwater management is better and fairer. Moreover, Hawke’s Bay residents living inside the collaborative catchment perceive less conflict over freshwater management than Hawke’s Bay respondents living outside the collaborative catchment. Further research is needed to identify the reasons for this regional variation.

Building peace by supporting post-conflict electoral processes

Les élections post-conflit ou élections de sortie de crise organisées sous l’égide de la communauté internationale en vue de rétablir la paix dans les pays sortant de violents conflits armés ont un bilan mixte caractérisé par le succès ou l’échec selon les cas. Ce bilan mitigé représente le problème principal auquel cette recherche tente de répondre à travers les questions suivantes : l’assistance électorale étrangère est-elle efficace comme outil de rétablissement de la paix dans les sociétés post-conflit? Qu’est ce qui détermine le succès ou l’échec des élections post-conflit à contribuer efficacement au rétablissement de la paix dans les sociétés déchirées par la guerre? Pour résoudre cette problématique, cette thèse développe une théorie de l’assistance électorale en période post-conflit centrée sur les parties prenantes à la fois du conflit armé et du processus électoral. Cette théorie affirme que l’élément clé pour le succès des élections post-conflit dans le rétablissement de la paix est le renforcement de la capacité de négociation des parties prenantes à la fois dans le processus de paix et dans le processus électoral post-conflit. Dans les situations post-conflit, une assistance électorale qui se voudrait complète et efficace devra combiner à la fois le processus électoral et le processus de paix. L’assistance électorale sera inefficace si elle se concentre uniquement sur les aspects techniques du processus électoral visant à garantir des élections libres, transparentes et équitables. Pour être efficace, l’accent devra également être mis sur les facteurs supplémentaires qui peuvent empêcher la récurrence de la guerre, tels que l’habilité des individus et des groupes à négocier et à faire des compromis sur les grandes questions qui peuvent menacer le processus de paix. De fait, même des élections transparentes comme celles de 1997 au Liberia saluées par la communauté internationale n’avaient pas réussi à établir des conditions suffisantes pour éviter la reprise des hostilités. C’est pourquoi, pour être efficace, l’assistance électorale dans les situations de post-conflit doit prendre une approche globale qui priorise l’éducation civique, la sensibilisation sur les droits et responsabilités des citoyens dans une société démocratique, le débat public sur les questions qui divisent, la participation politique, la formation au dialogue politique, et toute autre activité qui pourrait aider les différentes parties à renforcer leur capacité de négociation et de compromis. Une telle assistance électorale fera une contribution à la consolidation de la paix, même dans le contexte des élections imparfaites, comme celles qui se sont détenues en Sierra Leone en 2002 ou au Libéria en 2005. Bien que la littérature sur l’assistance électorale n’ignore guère l’importance des parties prenantes aux processus électoraux post-conflit (K. Kumar, 1998, 2005), elle a fortement mis l’accent sur les mécanismes institutionnels. En effet, la recherche académique et professionnelle est abondante sur la réforme des lois électorales, la reforme constitutionnelle, et le développement des administrations électorales tels que les commissions électorales, ainsi que l’observation électorale et autres mécanismes de prévention de la fraude électorale, etc. (Carothers & Gloppen, 2007). En d’autres termes, les décideurs et les chercheurs ont attribué jusqu’à présent plus d’importance à la conception et au fonctionnement du cadre institutionnel et des procédures électorales. Cette thèse affirme qu’il est désormais temps de prendre en compte les participants eux-mêmes au processus électoral à travers des types d’assistance électorale qui favoriseraient leur capacité à participer à un débat pacifique et à trouver des compromis aux questions litigieuses. Cette approche plus globale de l’assistance électorale qui replace l’élection post-conflit dans le contexte plus englobant du processus de paix a l’avantage de transformer le processus électoral non pas seulement en une expérience d’élection de dirigeants légitimes, mais aussi, et surtout, en un processus au cours duquel les participants apprennent à régler leurs points de vue contradictoires à travers le débat politique dans un cadre institutionnel avec des moyens légaux et légitimes. Car, si le cadre institutionnel électoral est important, il reste que le résultat du processus électoral dépendra essentiellement de la volonté des participants à se conformer au cadre institutionnel et aux règles électorales.

Good looks and good practice: the attitudes of career practitioners to attractiveness and appearance

Empirical evidence attests the impact that career image has on objective career success, yet little is known of how career practitioners conceptualise and operationalise this information. This article presents the quantitative findings of an online survey of career practitioners (n=399, 74% female, 89% white, 75% from the UK) exploring their attitudes and practices towards issues of appearance and attractiveness. Career practitioners who participated in this survey acknowledged that beauty, self-presentation and interpersonal skills influence career success, and 96% of them considered conversations about career image as part of their professional remit. The career practitioners felt relatively comfortable and well informed in their discussions in this arena, but would welcome further guidance and training to inform their practice. Ethical and practical implications for the profession are considered.

Performance-arte : fracasso, tempo e repetição

Vivemos um tempo de incerteza e instabilidade. Vivemos um tempo em que o presente se reproduz e se reinventa continuamente sem a perspectiva de um futuro certo e perdurável. A presente dissertação orienta-se em torno de um corpo de trabalho de experimentação artística que explora a relação entre arte contemporânea e fracasso. Trata-se, aqui, de reflectir sobre a natureza paradoxal do fracasso, sobre a utilidade e inutilidade do fracasso na sociedade e na artecontemporânea ocidental. Entre a intenção e a realização, entre a perspectiva de sucesso e o fracasso alcançado, abre-se um espaço gerador (potência)ocupado pela dúvida e questionamento, suporte essencial do pensamento e da acção humana. Corpo fracasso (descendente de Sísifo) dedicado a tarefas inúteis (nãoprodutivas) e repetitivas no tempo como alternativa ao corpo sucesso (base-docapitalismo), dedicado a tarefas úteis (produtivas) e repetitivas no tempo.

The ecology and evolution of invasive Potamopyrgus antipodarum in Australia

The spread of invasive organisms is one of the greatest threats to ecosystems and biodiversity worldwide. Understanding the evolutionary and ecological factors responsible for the transport, introduction, establishment and spread of invasive species will assist the development of control strategies. The New Zealand mudsnail, Potamopyrgus antipodarum (Gray 1843) (Gastropoda: Hydrobiidae), is a global freshwater invader, with populations established in Europe, Asia, the Americas and Australia. While sexual and asexual P. antipodarum coexist in the native range, invasive populations reproduce by parthenogenesis, producing dense populations that compete for resources with native species. Potamopyrgus antipodarum is a natural model system for the study of evolutionary and ecological processes underlying invasion. This thesis assesses the invasion history, genetic diversity and ecology of P. antipodarum in Australia, with particular focus on: a) potential source populations, b) distribution and structure of populations, and c) species traits related to the establishment, persistence and spread of invasive P. antipodarum. Genetic analyses were carried out on specimens collected for this study from New Zealand and Australia, along with existing museum samples. In combination with published data, the analyses revealed low genetic diversity among and within invasive populations in south-eastern Australia, relative to New Zealand populations. Phylogenetic relationships inferred from mitochondrial sequences indicated that the Australian populations belong to clades dominated by parthenogenetic haplotypes that are known to be present in Europe and the US. These ‘invasive clades’ are likely to originate from the North Island of New Zealand, and suggest a role for selection in determining genetic composition of invasive populations. The genotypic diversity of Australian P. antipodarum was low, with few, closely related clones distributed across south-eastern Australia. The pattern of clone distribution was not consistent with any assessed geographical or abiotic factors; instead a few, widely-distributed clones were present in high frequencies at most sites. Differences in clone frequencies were found, which may indicate differential success of clonal lineages. A range of traits have been proposed as facilitators of invasion success, and within-species variation in these traits can promote differential success of genotypes. Using laboratory-based experiments, the performance of the three most common Australian clones was tested across a suite of invasion-relevant traits. Ecologically-relevant variation in traits was found among the clones. These differences may have determined the spatial distribution of clones, and may continue to do so into the future. This thesis found that the P. antipodarum invasion of Australia is the result of few introductions of a small number of globally-invasive genotypes that vary in ecologically-relevant traits. From a source of considerable genetic diversity in the native range, very few genotypes have become invasive. Those that are invasive appear to be very successful at continental scales. These findings highlight a capacity in asexual invaders to successfully invade, and potentially adapt to, a broad range of ecosystems. The P. antipodarum invasion system is amenable to research using combinations of field-based studies, molecular and laboratory approaches, and is likely to yield significant, broadly-applicable insights into invasion.

Implantes colocados justa cristal versus implantes sub-cristal

Introdução: A posição da colocação do implante relativamente à crista óssea tem sido discutida na comunidade científica como fator influenciador de sucesso ou insucesso. Por outro lado a perda ou preservação óssea está intrinsecamente relacionado com fatores como a seleção do sistema de implante, o tipo de implante e a sua conexão. Objetivo: Este trabalho teve como objetivo a análise da bibliografia existente que compara a colocação de implantes a nível da crista óssea (justa cristal) com a colocação de implantes abaixo da crista óssea (sub-cristal) em sinergismo com outros fatores, de forma que seja percecionada a eficácia e sucesso na seleção efetuada. Metodologia: Procedeu-se a uma pesquisa bibliográfica através da identificação de artigos publicados em bases de dados eletrónicas internacionais, PubMed, B-on e Science Direct utilizando palavras-chave e critérios de exclusão e inclusão, que permitiram fazer uma seleção prévia dos artigos a incluir ao longo deste trabalho. Resultados: Após a realização da pesquisa bibliográfica obtiveram-se 63 artigos. A partir da amostra encontrada foram excluídos 26 artigos devido à falta de correspondência do seu conteúdo ao tema proposto e 14 por se encontrarem repetidos ou sem dados comparativos. Nos 23 artigos aceites encontram-se incluídos estudos animais, elementos finitos, revisões e estudos clínicos. Conclusão: Os resultados sugerem que a colocação de implantes em sub-cristal apresenta-se como uma melhor solução na preservação da crista óssea, no entanto há que levar em conta outros fatores associados diretamente ao implante, nomeadamente, a geometria, superfície não polida do colo assim como o tipo de conexão do pilar ao implante, onde foi encontrada uma relativa evidência de melhor eficácia no que respeita à conexão do tipo “cone Morse”.

Impacts of Deepwater Horizon oil and associated dispersant on early development of the Eastern oyster Crassostrea virginica

The explosion of the Deepwater Horizon (DWH) oil platform resulted in large amounts of crude oil and dispersant Corexit 9500A® released into the Gulf of Mexico and coincided with the spawning season of the oyster, Crassostrea virginica. The effects of exposing gametes and embryos of C. virginica to dispersant alone (Corexit), mechanically (HEWAF) and chemically dispersed (CEWAF) DWH oil were evaluated. Fertilization success and the morphological development, growth, and survival of larvae were assessed. Gamete exposure reduced fertilization (HEWAF: EC201 h = 1650 μg tPAH50 L− 1; CEWAF: EC201 h = 19.4 μg tPAH50 L− 1; Corexit: EC201 h = 6.9 mg L− 1). CEWAF and Corexit showed a similar toxicity on early life stages at equivalent nominal concentrations. Oysters exposed from gametes to CEWAF and Corexit experienced more deleterious effects than oysters exposed from embryos. Results suggest the presence of oil and dispersant during oyster spawning season may interfere with larval development and subsequent recruitment.

Creating and measuring customer value in digital businesses

Most economic transactions nowadays are due to the effective exchange of information in which digital resources play a huge role. New actors are coming into existence all the time, so organizations are facing difficulties in keeping their current customers and attracting new customer segments and markets. Companies are trying to find the key to their success and creating superior customer value seems to be one solution. Digital technologies can be used to deliver value to customers in ways that extend customers’ normal conscious experiences in the context of time and space. By creating customer value, companies can gain the increased loyalty of existing customers and better ways to serve new customers effectively. Based on these assumptions, the objective of this study was to design a framework to enable organizations to create customer value in digital business. The research was carried out as a literature review and an empirical study, which consisted of a web-based survey and semi-structured interviews. The data from the empirical study was analyzed as mixed research with qualitative and quantitative methods. These methods were used since the object of the study was to gain deeper understanding about an existing phenomena. Therefore, the study used statistical procedures and value creation is described as a phenomenon. The framework was designed first based on the literature and updated based on the findings from the empirical study. As a result, relationship, understanding the customer, focusing on the core product or service, the product or service quality, incremental innovations, service range, corporate identity, and networks were chosen as the top elements of customer value creation. Measures for these elements were identified. With the measures, companies can manage the elements in value creation when dealing with present and future customers and also manage the operations of the company. In conclusion, creating customer value requires understanding the customer and a lot of information sharing, which can be eased by digital resources. Understanding the customer helps to produce products and services that fulfill customers’ needs and desires. This could result in increased sales and make it easier to establish efficient processes.

New Foods, New Consumers: Innovation in Food Product Development

BACKGROUND: Today, new lifestyles, higher incomes and consumer awareness are creating consumer demand for a year-round supply of high-quality, diverse and innovative food products. However, when it comes to innovation, the food sector is less changeable when compared to other sectors, such as high technology. Still, in the past decades much and important developments have been achieved in several areas related to foods and the food industry. METHODS: A systematic review of scientific literature was conducted on Science Direct. The topics investigated were: aspects related to innovation in food development (such as the transfer of innovation, open innovation, collaborative innovation and consumer perception and its role in the developing process); the innovation in the food industry (particularly regarding the processing technologies and packaging, which are two prominent areas of innovation in this sector nowadays); the innovation in the cooking sector (particularly in regards to the molecular gastronomy and science based cooking). RESULTS: A total of 146 articles were included in the review and the aspects focused allowed confirming that innovation has been recognized as a key driver of economic growth. Within the framework of ‘open innovation’, a number of key issues related to the acquisition of external knowledge in food technology must be taken into consideration. Food product development is highly dependent on the consumer perception and acceptance, and hence it is of utmost importance to include the consumer in the development process to minimize failure probabilities. The sectors of the food industry where important developments and innovation are registered include the processing technologies and the packaging systems, where the latest progresses have produced very significant outcomes. CONCLUSION: The present work allowed verifying the latest improvements and trend towards food product development from two perspectives, the product itself and the industrial processing. This sector is undoubtedly a major key for the success and competitiveness nowadays in the food industry.

Role of climate on barn owls road-kill likelihood and the effect on population viability in future climate change

Roads represent a new source of mortality due to animal-vehicle risk of collision threatening log-term populations’ viability. Risk of road-kill depends on species sensitivity to roads and their specific life-history traits. The risk of road mortality for each species depends on the characteristics of roads and bioecological characteristics of the species. In this study we intend to know the importance of climatic parameters (temperature and precipitation) together with traffic and life history traits and understand the role of drought in barn owl population viability, also affected by road mortality in three scenarios: high mobility, high population density and the combination of previous scenarios (mixed) (Manuscript). For the first objective we correlated the several parameters (climate, traffic and life history traits). We used the most correlated variables to build a predictive mixed model (GLMM) the influence of the same. Using a population model we evaluated barn owl population viability in all three scenarios. Model revealed precipitation, traffic and dispersal have negative relationship with road-kills, although the relationship was not significant. Scenarios showed different results, high mobility scenario showed greater population depletion, more fluctuations over time and greater risk of extinction. High population density scenario showed a more stable population with lower risk of extinction and mixed scenario showed similar results as first scenario. Climate seems to play an indirect role on barn owl road-kills, it may influence prey availability which influences barn owl reproductive success and activity. Also, high mobility scenario showed a greater negative impact on viability of populations which may affect their ability and resilience to other stochastic events. Future research should take in account climate and how it may influence species life cycles and activity periods for a more complete approach of road-kills. Also it is important to make the best mitigation decisions which might include improving prey quality habitat.

An examination of factors influencing ERP key-user satisfaction: A qualitative case study

Several companies are trying to improve their operation efficiency by implementing an enterprise resource planning (ERP) system that makes it possible to control the resources of the company in real time. However, the success of the implementation project is not a foregone conclusion; a significant part of these projects end in a failure, one way or another. Therefore it is important to investigate ERP system implementation more closely in order to increase understanding about factors influencing ERP system success and to improve the probability of a successful ERP implementation project. Consequently, this study was initiated because a manufacturing case company wanted to review the success of their ERP implementation project. To be exact, the case company hoped to gain both information about the success of the project and insight for future implementation improvement. This study investigated ERP success specifically by examining factors that influence ERP key-user satisfaction. User satisfaction is one of the most commonly applied indicators of information system success. The research data was mainly collected by conducting theme interviews. The subjects of the interviews were six key-users of the newly implemented ERP system. The interviewees were closely involved in the implementation project. Furthermore, they act as representative users that utilize the new system in everyday business processes. The collected data was analyzed by thematizing. Both data collection and analysis were guided by a theoretical frame of reference. This frame was based on previous research on the subject. The results of the study aligned with the theoretical framework to large extent. The four principal factors influencing key-user satisfaction were change management, contractor service, key-user’s system knowledge and characteristics of the ERP product itself. One of the most significant contributions of the research is that it confirmed the existence of a connection between change management and ERP key-user satisfaction. Furthermore, it discovered two new sub-factors influencing contractor service related key-user satisfaction. In addition, the research findings indicated that in order to improve the current level of key-user satisfaction, the case company should pay special attention to system functionality improvement and enhancement of the key-users’ knowledge. During similar implementation projects in the future, it would be important to assure the success of change management and contractor service related processes.

Men's experiences of receiving objective feedback on physical activity and other indicators of health risk, within the context of a gender-sensitised weight loss intervention

Receiving personalised feedback on body mass index and other health risk indicators may prompt behaviour change. Few studies have investigated men’s reactions to receiving objective feedback on such measures and detailed information on physical activity and sedentary time. The aim of my research was to understand the meanings different forms of objective feedback have for overweight/obese men, and to explore whether these varied between groups. Participants took part in Football Fans in Training, a gender-sensitised, weight loss programme delivered via Scottish Professional Football Clubs. Semi-structured interviews were conducted with 28 men, purposively sampled from four clubs to investigate the experiences of men who achieved and did not achieve their 5% weight loss target. Data were analysed using the principles of thematic analysis and interpreted through Self-Determination Theory and sociological understandings of masculinity. Several factors were vital in supporting a ‘motivational climate’ in which men could feel ‘at ease’ and adopt self-regulation strategies: the ‘place’ was described as motivating, whereas the ‘people’ (other men ‘like them’; fieldwork staff; community coaches) provided supportive and facilitative roles. Men who achieved greater weight loss were more likely to describe being motivated as a consequence of receiving information on their objective health risk indicators. They continued using self-monitoring technologies after the programme as it was enjoyable; or they had redefined themselves by integrating new-found activities into their lives and no longer relied on external technologies/feedback. They were more likely to see post-programme feedback as confirmation of success, so long as they could fully interpret the information. Men who did not achieve their 5% weight loss reported no longer being motivated to continue their activity levels or self-monitor them with a pedometer. Social support within the programme appeared more important. These men were also less positive about objective post-programme feedback which confirmed their lack of success and had less utility as a motivational tool. Providing different forms of objective feedback to men within an environment that has intrinsic value (e.g. football club setting) and congruent with common cultural constructions of masculinity, appears more conducive to health behaviour change.

The timing and interval of mate encounter affects investment during mating

The benefits obtained from mating are usually condition-dependent, favouring the evolution of flexible investment during copulation, for instance, in terms of invested time, energy, or sperm. Flexible investment strategies are predicted to depend on the likelihood of acquiring alternative mates and therefore they should depend on the timing of mate encounter. However, scarce experimental evidence for this hypothesis exists. Here we manipulated the time delay until first mating and the interval between first and second mating in the polygynandrous common lizard, Zootoca vivipara. We determined treatment effects on fertilisation success and copulation duration, the latter being a proxy for investment in mating and for quantity of transferred sperm. The duration of the second copulation decreased with increasing inter-mating interval and depended on the fertilisation success of first mates. The former provides evidence for time-dependent investment strategies, most likely resulting from the progression of the female's reproductive cycle. Fertilisation success of first mates increased with increasing inter-mating interval and was higher when females were closer to ovulation, showing that flexible investment strategies significantly affected male reproductive success. This points to fertilisation assurance, which may mitigate negative effects of low population density on reproductive success, e.g. Allee effects.
