Treating wastewater by indigenous microalgae strain in pilot platform located inside a municipal wastewater treatment plant
No full textVarious resources from a municipal wastewater treatment plant (MWTP) are available for microalgae cultivation plants, suggesting that a combination of these technologies can be used to produce microalgae biomass and remove contaminants at a low cost. In this study, the growth performance and nutrient removal efficiency of an indigenous Scenedesmus sp. in various wastewater media with different exchange patterns were investigated firstly, then transferred to a pilot-scale photobioreactor (located inside a MWTP) for bioremediation use. The temperature and pH of the platform were maintained at 15–30°C and 7.6, respectively. The NH+4− N, NO−3− N, and PO3−4− P of the wastewater could be reduced to below 0.05, 0.40, and 0.175 mg L–1, respectively. Our results indicate that microalgae cultivation using the resources of a MWTP can achieve high algal biomass productivity and nutrient removal rate. Our study also suggests that efficient technology for controlling zooplankton needs to be developed
Effect of Temperature on Electromagnetic Performance of Active Phased Array Antenna
Get PDFActive phased array antennas (APAAs) can suffer from the effects of harsh thermal environments, which are caused by the large quantity of power generated by densely packed T/R modules and external thermal impacts. The situation may be worse in the case of limited room and severe thermal loads, due to heat radiation and a low temperature sink. The temperature field of the antenna can be changed. Since large numbers of temperature-sensitive electronic components exist in T/R modules, excitation current output can be significantly affected and the electromagnetic performance of APAAs can be seriously degraded. However, due to a lack of quantitative analysis, it is difficult to directly estimate the effect of temperature on the electromagnetic performance of APAAs. Therefore, this study investigated the electromagnetic performance of APAAs as affected by two key factors—the uniformly distributed temperature field and the temperature gradient field—based on different antenna shapes and sizes, to provide theoretical guidance for their thermal design
The implementation of sustainable leadership in general further education colleges
Get PDFSustainable leadership as a concept is both in its infancy and also under researched, with much of the previous work in the area concentrating solely on the compulsory sector. Lambert (2011) argues that existing models are not entirely appropriate for further education due to the landscape in which colleges operate. This paper presents the findings of empirical work which sought the views of principals of general further education colleges (equivalent to United States Community Colleges) in the south east of England and London, UK, as to whether they are in agreement with the component aspects of the framework of
sustainable leadership for further education colleges suggested by Lambert (2011)
Sustainable leadership and its implications for the general further education college sector
No full textThe purpose of this article is to review the models of sustainable leadership
which are currently available in the compulsory sector to establish whether the models are appropriate for post-compulsory education, and in particular for general further education colleges. Due to the complexities of the environment in which further education colleges operate, models of sustainable leadership have not been applied to this sector. In order to achieve this, leadership challenges for further education will be explored and the sector’s responses to these will be considered. Many of these challenges are based on government pressure for efficiency and effectiveness savings, and so will be contextualised in a new managerial framework. The article then goes on to examine current models of sustainable leadership, looking at whether they are applicable for general further education colleges. Should they not be appropriate, then a suggested model will be put forward which draws on the transferable components for existing models with additions which are appropriate to the post-compulsory sector
Seascape genomics reveals population isolation in the reef-building honeycomb worm, Sabellaria alveolata (L.)
Get PDFBackground: Under the threat of climate change populations can disperse, acclimatise or evolve in order to avoid fitness loss. In light of this, it is important to understand neutral gene flow patterns as a measure of dispersal potential, but also adaptive genetic variation as a measure of evolutionary potential. In order to assess genetic variation and how this relates to environment in the honeycomb worm (Sabellaria alveolata (L.)), a reef-building polychaete that supports high biodiversity, we carried out RAD sequencing using individuals from along its complete latitudinal range. Patterns of neutral population genetic structure were compared to larval dispersal as predicted by ocean circulation modelling, and outlier analyses and genotype-environment association tests were used to attempt to identify loci under selection in relation to local temperature data.
Results: We genotyped 482 filtered SNPs, from 68 individuals across nine sites, 27 of which were identified as outliers using BAYESCAN and ARLEQUIN. All outlier loci were potentially under balancing selection, despite previous evidence of local adaptation in the system. Limited gene flow was observed among reef-sites (FST = 0.28 ± 0.10), in line with the low dispersal potential identified by the larval dispersal models. The North Atlantic reef emerged as a distinct population and this was linked to high local larval retention and the effect of the North Atlantic Current on dispersal.
Conclusions: As an isolated population, with limited potential for natural genetic or demographic augmentation from other reefs, the North Atlantic site warrants conservation attention in order to preserve not only this species, but above all the crucial functional ecological roles that are associated with their bioconstructions. Our study highlights the utility of using seascape genomics to identify populations of conservation concern

An exploratory study of the FinTech (Financial Technology) education and retraining in UK
Get PDFPurpose
The purpose of this paper is to explore two identified knowledge gaps: first, the identification and analysis of online searching trends for Financial Technology (FinTech)-related jobs and education information in UK, and second to assess the current strength of the FinTech-related job distribution in terms of job titles and locations in UK, job market in UK and what is required to help it to grow.
Design/methodology/approach
Two sets of data were used in this study in order to fill the two identified knowledge gaps. First, six years’ worth of data, for the period from September 2012 to August 2018 was collected from Google Trends. This was in the form of search term keyword text. The hypothesis was designed correspondingly, and the results were reviewed and evaluated using a relevant statistical tool. Second, relevant data were extracted from the “Indeed” website (www.indeed.co.uk) by means of a simple VBA programme written in Excel. In total, the textual data for 500 job advertisements, including the keyword “FinTech”, were downloaded from that website.
Findings
The authors found that there was a continuously increasing trend in the use of the keyword “fintech” under the category “Jobs and Education” in online searching from September 2012 to August 2018. The authors demonstrated that this trend was statistically significant. In contrast, the trends for searches using both “finance” and “accounting” were slightly decreased over the same period. Furthermore, the authors identified the geographic distribution of the fintech-related jobs in the UK. In regard to job titles, the authors discovered that “manager” was the most frequently searched term, followed by “developer” and “engineer”.
Research limitations/implications
Educators could use this research as a reference in the development of the portfolio of their courses. In addition, the findings from this study could also enable potential participators to reflect on their career development. It is worth noting that the motivations for carrying out an internet search are complex, and each of these needs to be understood. There are many factors that would affect how an information seeker would behave with the obtained information. More work is still needed in order to encourage more people to enter to the FinTech sector.
Originality/value
In the planning stage prior to launching a new course educators often need to justify the market need: this analysis could provide a supporting rationale and enable a new course to launch more quickly. Consequently, the pipeline of talent supply to the sector would also be benefitted. The authors believe this is the first time that a study like this had been conducted to explore specifically the availability and opportunities for FinTech education and retraining in UK. The authors anticipate that this study will become the primary reference for researchers, educators and policy makers engaged in future research or practical applications on related topics
Putnam and Radical Socio-Economic Theory.
No full textPurpose – The purpose of this paper is to review the social capital treatment of Robert Putnam, the
most influential conceptual theorist. The paper will detail how Putnam’s treatment of social capital has
evolved, examine the arguments of his critics and will also critique his socio-economic analysis.
Design/methodology/approach – The approach taken is a literature review that investigates
Putnam’s social capital understanding and considers the reasons why this conceptual treatment
“touched a nerve” and proved so influential and adaptable.
Findings – Putnam’s social capital treatment belongs to a socio-economic communitarian tradition
that can be traced to de-Tocqueville, which offers an alternative to both mainstream free market
ideology and to leftwing socio-economics.
Originality/value – The originality of this paper is to identify Putnam as a radical in a
methodological sense, reinvigorating a Burkean, consensual interpretation of socio-economics. The
value of this paper is to offer a critique of Putnam’s interpretation of social capital.

Introducing experiences from African pastoralist communities to cope with climate change risks, hazards and extremes: Fostering poverty reduction
No full textThis article is not available on ChesterRepPastoralist communities all over Africa have been facing a variety of social and economic problems, as well as climate risks and hazards for many years. They have also been suffering from climate change and extremes events, along with a variety of weather and climate threats, which pose many challenges to herders. On the one hand, pastoralist communities have little influence on policy decisions; however, on the other hand, they suffer to a significant extent from such policies, which limit their options for sustainable development and poverty alleviation. Also, the socio-cultural legacy of herders, and their role in food security and provision of ecosystem services, as well as their efforts towards climate change adaptation, are little documented, particularly in Eastern and Southern African countries. There is a perceived need for international studies on the risks and impacts of climate change and extreme events on the sustainability of pastoralist communities in Africa, especially in eastern and southern Africa. Based on the need to address this research gap, this paper describes the climate change risks and challenges that climate threats pose to the sustainability and livelihoods of pastoralist communities in eastern and southern Africa. Also, it discusses the extent to which such problems affect their well-being and income. Additionally, the paper reports on the socioeconomic vulnerability indices at country-level. Also, it identifies specific problems pastoralists face, and a variety of climate adaptation strategies to extreme events through field survey among pastoralist communities in a sample of five countries, namely Ethiopia, Kenya, Malawi, Uganda, and Zimbabwe. The study has shown that the long-term sustainability of the livelihoods of pastoral communities is currently endangered by climate change and the risks and hazards it brings about, which may worsen poverty among this social group. Also, the study suggests that a more systematic and structured approach is needed when assessing the climate vulnerability of individual pastoral communities, since this may help in designing suitable disaster risk reduction strategies. Moreover, the paper shows that it is also necessary to understand better the socio-ecological systems (SES) of the various communities, and how their livelihoods are influenced by the changing conditions imposed by a changing climate
