Abstract

There is a need to expand the range of analytical techniques which can be used to analyse the organic components of geoforensic trace evidence in order to allow the discrimination of more forensically relevant soils, situated at smaller distances from one another. Existing analytical techniques used in forensic geoscience are based on the analysis of the inorganic fraction of soil, which is often consistent across several kilometers, therefore a complementary analytical technique is required in order to maximise the evidential value of soils and sediments. HPLC has been proposed here as a suitable method, and during method development the most appropriate methods for handling and analysing soil evidence by HPLC were selected, producing a method that is significantly more sensitive, less costly, complicated and time consuming than the methods proposed by previous authors. The feasibility of reliably excluding soil samples from locations situated approximately 250m apart using the new HPLC method was demonstrated, and 100% accuracy (p=0.000) was obtained by performing canonical discriminant function analysis on the resulting HPLC data. The highly complex chromatograms obtained present challenges during data analysis which were resolved by selecting two subsets of markers, each containing a reduced number of peaks than the initial data set. This experiment was repeated at three UK sites, over 12-18 months, and at one site in the USA, and HPLC was shown to offer extremely high accuracy rates in discriminating samples at all four sites and therefore to be robust to changes in underlying geology, and to provide highly accurate discrimination at all time points, and to be robust to delays between sample collection and analysis. Collaborative experiments were undertaken, in which HPLC samples were re-analysed using quartz grain surface texture analysis, and wax marker profiling by GC, and HPLC was shown to offer better discrimination at this close-proximity spatial scale, in addition to offering potential benefits in regulated and commercialised forensic science laboratories due to its simplicity and efficiency.

Abstract

The diadematid sea urchin Centrostephanus rodgersii occurs in Australia and New Zealand and has undergone recent southward range extension in Australia as a result of regional warming. Clarifying the population genetic structure of this species across its New Zealand range would allow a better understanding of recent and future mechanisms driving range changes in the species. Here, we use microsatellite DNA data to assess connectivity and genetic structure in 385 individuals from 14 locations across the Australian and New Zealand ranges of the species. We detected substantial genetic differentiation among C. rodgersii populations from Australia and New Zealand. However, the population from Port Stephens (located north of Newcastle), Australia, strongly clustered with New Zealand samples. This suggests that the New Zealand populations recently originated from this area, likely via larval transport in the Tasman Front flow that arises in this region. The weak population genetic structure and relatively low genetic diversity detected in New Zealand (global F.sub.st = 0.0021) relative to Australia (global F.sub.st = 0.0339) is consistent with the former population's inferred history of recent climate-driven expansion. Population-level inbreeding is low in most populations, but were higher in New Zealand (global F.sub.is = 0.0833) than in Australia (global F.sub.is = 0.0202), suggesting that self-recruitment is playing an increasingly important role in the New Zealand region. Our results suggest that C. rodgersii is likely to spread southwards as ocean temperatures increase; therefore, it is crucial that researchers develop a clearer understanding of how New Zealand ecosystems will be reshaped by this species (and others) under climate change., Author(s): L.

Abstract

Our minds are still racing back and forth, longing for a return to ‘normality’, trying to stitch our future to our past and refusing to acknowledge the rupture. But the rupture exists. And in the midst of this terrible despair, it offers us a chance to rethink the doomsday machine we have built for ourselves. Nothing could be worse than a return to normality. Historically, pandemics have forced humans to break with the past and imagine their world anew. This one is no different. It is a portal, a gateway between one world and the next. We can choose to walk through it, dragging the carcasses of our prejudice and hatred, our avarice, our data banks and dead ideas, our dead rivers and smoky skies behind us. Or we can walk through lightly, with little luggage, ready to imagine another world. And ready to fight for it.

13. Two grain beetle species, one resource, different patterns of genetic structure: implications for management

Author

McCulloch, G. A., Daglish, Gregory J., Walter, G. H., McCulloch, G. A., Daglish, Gregory J., and Walter, G. H.

Abstract

Rhyzopertha dominica and Tribolium castaneum are key pests of stored grains globally. These two species often occur together in infestations, and are seldom found outside the agricultural environment. Understanding the movement of these beetle pests is crucial for the development of management strategies, in particular to prevent the spread of phosphine resistance, which is a serious issue in many countries. We sampled both of these beetle species from farm silos across Australia, and used microsatellite markers to assess whether these two pests sharing the same resource show similar patterns of genetic diversity and genetic structure. Both species had high levels of genetic diversity, and showed some evidence of genetic structure across Australia, but the patterns of genetic structure differed across the two species. Specifically, our results suggest that there is significant gene flow in T. castaneum across Australia, with the clear isolation-by-distance pattern indicating that active flight may play an important role in determining genetic structure in this species. The significant movement of T. castaneum beetles across Australia will likely result in the continued spread of phosphine resistance alleles across Australia, leading to increased incidence of strongly resistance populations. Less gene flow was evident in R. dominica, suggesting movement of these beetles among localities is more restricted. Our results demonstrate that pests mostly sharing the same resources can significantly differ in their genetic structure and genetic diversity, suggesting species-specific management practices are essential.

Abstract

Recent biological analyses suggest that reductions in dispersal ability have beenkey drivers of diversification across numerous lineages. We synthesise emergingdata to highlight similarities regarding the causes and consequences of dispersalreduction across taxa and ecosystems, as well as the diverse genomic mechanismsunderpinning these shifts. Natural selection has acted on standing genetic variationwithin taxa to drive often rapid–and in some cases parallel–losses of dispersal,and ultimately speciation. Such shifts can thus represent an important nexus be-tween adaptive and neutral diversification processes, with substantial evolutionaryconsequences. Recognition of the links between these concepts that are emergingfrom differentfields, taxa and ecosystems is transforming our understanding of thefascinating role of dispersal reduction in the formation of biodiversity.

18. Significant population genetic structuring in Rhyzopertha dominica across Turkey: Biogeographic and practical implications

Abstract

Rhyzopertha dominica is a key pest of stored grain. Understanding the movement of this beetle on broad geographic scales is crucial, particularly when developing strategies to prevent the spread of phosphine resistance. We assessed population genetic structuring in this pest across Turkey, using a combination of mitochondrial (cytochrome oxidase I) and microsatellite markers. In addition, we screened samples for Wolbachia, as this endosymbiont has previously been suggested to be associated with low mitochondrial genetic diversity in this beetle. Mitochondrial genetic diversity was low, with only six haplotypes identified. The genetic diversity was, however, substantially higher than that previously found in Australia or India, suggesting that R. dominica may have originated in the Middle East. Wolbachia were detected only at a single site, indicating they are not impacting the mitochondrial genetic diversity of R. dominica across Turkey. Microsatellite markers indicated there is significant geographic genetic structuring across Turkey, even among sites less than 100 km apart, suggesting there is little movement of beetles across regions within the country. This contrasts with the significantly higher levels of gene-flow found in Australia and the United States. We suggest that the limited movement of beetles across Turkey may be due to a combination of the historically localised agricultural practices (which limits anthropogenic movement among regions), and the mountainous landscape (which limits active flight among regions). Our results demonstrate that the movement of stored product pests may differ significantly across studies conducted in different countries. As a consequence, phosphine resistance management strategies must incorporate region specific information on the extent of beetle movement.

Abstract

As with most social practices, teaching is not an invention of the Age of Enlightenment but a “natural” part of any transfer of knowledge and skills and therefore an anthropological “fact.” What makes teachers and teaching a privileged subject of research in the Age of Enlightenment is a particular shift in the meaning of teaching and a modified significance of being a teacher. The two terms–teachers and teaching–underwent a shift as part of a larger movement labeled as the “educationalization of social problems”. This concept addresses the belief that social problems can or actually should be solved through education; primarily through the education of the younger generation, but also through the education of adults. All the undertaken attempts and actions corresponding to this shift counted either on the rationality of humans, concepts like common sense, perfectibility, and individual improvement, but also on the impact of aesthetics and emotion and appealed to morality. In the educationalization process, the teacher turned out to be the personification of these educational ambitions, and the pedagogical efforts to implement and guarantee these ambitions has since increased. According to these remarks, the chapter takes examples from different European regions and discusses teachers and teaching in institutional (formal) settings, e.g. in universities, academies, schools, and the like. It takes a look at teachers’ education, at their social status, at their pedagogical ideas and tools, and at the teaching materials. In this way, the history of teachers and of the practice of teaching are interwoven with an institutional history of schooling, as institutional settings do preconfigure the relevant practices at least to a certain degree. The second part deals with teachers and teaching in informal settings, with the several forms of popular enlightenment, from political pamphlets to economic treatises and moral publications, takes the related group of actors into acc

Abstract

Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite telemetry, we need an in-depth understanding of the main technological, species-specific and environmental factors that determine the success and failure of satellite tracking devices across species and habitats. Here, we assess the relative influence of such factors on the ability of satellite telemetry units to provide the expected amount and quality of data by analyzing data from over 3,000 devices deployed on 62 terrestrial species in 167 projects worldwide. We evaluate the success rate in obtaining GPS fixes as well as in transferring these fixes to the user and we evaluate failure rates. Average fix success and data transfer rates were high and were generally better predicted by species and unit characteristics, while environmental characteristics influenced the variability of performance. However, 48% of the unit deployments ended prematurely, half of them due to technical failure. Nonetheless, this study shows that the performance of satellite telemetry applications has shown improvements over time, and based on our findings, we provide further recommendations for both users and manufacturers.

Abstract

Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite telemetry, we need an in-depth understanding of the main technological, species-specific and environmental factors that determine the success and failure of satellite tracking devices across species and habitats. Here, we assess the relative influence of such factors on the ability of satellite telemetry units to provide the expected amount and quality of data by analyzing data from over 3,000 devices deployed on 62 terrestrial species in 167 projects worldwide. We evaluate the success rate in obtaining GPS fixes as well as in transferring these fixes to the user and we evaluate failure rates. Average fix success and data transfer rates were high and were generally better predicted by species and unit characteristics, while environmental characteristics influenced the variability of performance. However, 48% of the unit deployments ended prematurely, half of them due to technical failure. Nonetheless, this study shows that the performance of satellite telemetry applications has shown improvements over time, and based on our findings, we provide further recommendations for both users and manufacturers.

Abstract

Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite telemetry, we need an in-depth understanding of the main technological, species-specific and environmental factors that determine the success and failure of satellite tracking devices across species and habitats. Here, we assess the relative influence of such factors on the ability of satellite telemetry units to provide the expected amount and quality of data by analyzing data from over 3,000 devices deployed on 62 terrestrial species in 167 projects worldwide. We evaluate the success rate in obtaining GPS fixes as well as in transferring these fixes to the user and we evaluate failure rates. Average fix success and data transfer rates were high and were generally better predicted by species and unit characteristics, while environmental characteristics influenced the variability of performance. However, 48% of the unit deployments ended prematurely, half of them due to technical failure. Nonetheless, this study shows that the performance of satellite telemetry applications has shown improvements over time, and based on our findings, we provide further recommendations for both users and manufacturers.

38. Flight of Rhyzopertha dominica (Coleoptera: Bostrichidae)—a Spatio-Temporal Analysis With Pheromone Trapping and Population Genetics

Abstract

The flight of the lesser grain borer, Rhyzopertha dominica (F.), near grain storages and at distances from them, was investigated to assess the potential of these beetles to infest grain and spread insecticide resistance genes. We caught R. dominica in pheromone-baited flight traps (and blank controls) set at storages, in fields away from storages, and in native vegetation across a 12-mo period. A functional set of highly polymorphic microsatellite markers was developed, enabling population genetic analyses on the trapped beetles. Pheromone-baited traps caught just as many R. dominica adults at least 1 km from grain storages as were caught adjacent to grain storages. Samples of beetles caught were genetically homogeneous across the study area (over 7,000 km2) in South Queensland, Australia. However, a change in genetic structure was detected at one bulk storage site. Subsequent analysis detected a heterozygous excess, which indicated a population bottleneck. Only a few beetles were caught during the winter months of June and July. To assess the mating status and potential fecundity of dispersing R. dominica females, we captured beetles as they left grain storages and quantified offspring production and life span in the laboratory. Nearly all (95%) of these dispersing females had mated and these produced an average of 242 offspring. We demonstrated that R. dominica populations in the study area display a high degree of connectivity and this is a result of the active dispersal of mated individuals of high potential fecundity.

Abstract

The steel industry is one of the first industries where operational research was successfully applied. The objective of the present paper is to summarize such applications high-lighting benefits and difficulties involved in the studies and in their subsequent implementation.
The paper is divided into three sections. The first section contains a brief survey of the reported case studies in literature pertaining to the application of O.R. techniques and methodology in production problems in the steel industry. The second section deals with a few case studies which illustrate the model building procedures and their usefulness in real life.
The final section of the paper is devoted to a discussion of the potential areas where O.R. techniques and methodology can be fruitfully applied in modeling production processes for control purposes. [ABSTRACT FROM AUTHOR]

44. Lesser Flamingo Phoeniconaias minor as a nomadic species in African shallow alkaline lakes and pans: genetic structure and future perspectives

Abstract

The Lesser Flamingo Phoeniconaias minor is a nomadic species, which inhabits shallow alkaline lakes and pans in sub-Saharan Africa and southern Asia. The extent of genetic diversity and the degree of differentiation within and among populations are important factors to determine in order to help manage and conserve the species, categorised as Near Threatened by the IUCN. This study provides an assessment of the population structure of the two largest African populations of P. minor by genotyping six microsatellite loci from 30 individuals sampled on Lake Bogoria (Kenya) and 11 individuals from Makgadikgadi Sua Pan (Botswana). The alleles detected per locus ranged from four to 13. The Lake Bogoria population harboured 15 specific alleles, whereas the Makgadikgadi Sua Pan population only six alleles. Moderate genetic diversity (He = 0.64–0.69) was comparable with populations that have not suffered from demographic bottlenecks or inbreeding. The populations are genetically similar with little differentiation (FST and RST not significantly different from zero). Small but continuous gene flow (the estimated average number of individuals exchanged is 3–4 per generation) was found, probably reflecting the bird’s nomadic behaviour and the natural presence of temporary shallow waters between the two sampled populations. The results suggest that inbreeding effects at present are unlikely, and hence that the loss and/or degradation of its specialised habitat remains the primary concern for the species’ continued survival.OSTRICH 2011, 82(2): 95–100

Abstract

A key issue for geoforensic analysis is the ability to discriminate between geographical locations of close proximity, often with similar underlying geology. This paper addresses the lack of empirical research into the non-mineral components of sediment samples and presents the development of a method of sediment sample characterisation by High Performance Liquid Chromatography (HPLC) utilising the organic components of the sample. A sample preparation method and set of instrument parameters were developed such that the cost of the analysis could be reduced, efficiency increased and the sample amount required for analysis reduced fourfold. The re-developed method allows samples collected from different locations within the same forensically relevant site to be accurately discriminated in this study by both visual examination of the chromatography and the use of multivariate statistics. The results of the HPLC analysis were compared with those obtained by quartz grain surface texture analysis, and HPLC was found to offer better discrimination between the samples in this instance. The results of this study suggest that HPLC has the potential to offer an accurate and practical method of comparing soil samples based on characteristics that are independent of, and therefore complementary to, traditional mineralogical-based geoforensic analyses.

Abstract

Despite commercial operation since 1991 by Botswana Ash (BotAsh), which has 98 wells and a 400 km2 network of pipes, evaporation ponds and processing facilities producing NaCl, Na2CO3, Na2SO4 and NaHCO3, little is known about the chemistry and hydrology of the system as a whole. The study found that hyper-saline subsurface brine is homogenous, with minor variations due to the BotAsh mine pumping 2 400 m3/h from a depth of 38 m. The salt content decreases as the pumping rate increases, which may indicate subsurface recharge by less saline water. Isotope chemistry suggests subsurface brines have been subject to a lithological contribution. Recharge of the subsurface brine from surface water including the Nata River appears to be negligible., Despite commercial operation since 1991 by Botswana Ash (BotAsh), which has 98 wells and a 400 km2 network of pipes, evaporation ponds and processing facilities producing NaCl, Na2CO3, Na2SO4 and NaHCO3, little is known about the chemistry and hydrology of the system as a whole.

49. Critical Theory

Abstract

Critical theory emerged in Germany in the 1920s with the establishment of the Institute for Social Research at Frankfurt-am Main in 1923. The term ‘critical theory’ was originally coined and used by Max Horkheimer in 1937 to describe the theoretical programme of the school. Known as the ‘Frankfurt School’ the group became exiled to France then to the United States in the early 1930s until 1941 when it closed down. According to Löwenthal (1989: 141) the decision to emigrate from Germany was made as early as 1930 as a consequence of the rise of the Nazi’s to political power and the increasingly difficult situation faced by a group of intellectuals that was predominantly Jewish. Amongst its members were Max Horkheimer, Theodor Adorno, Herbert Marcuse, Frederich Pollock, Franz Neumann, Leo Löwenthal and Erih Fromm. In 1934 the group were given permission to establish their Institute at Columbia University in New York. After the war, in 1950, it was reestablished in Frankfurt where it attracted new members such as Jürgen Habermas and Alfred Schmidt.

50. Education Policy

Abstract

In contrast to traditional pluralist or functionalist analyses, the last thirty years has seen the emergence of what is now referred to as a critical policy analysis. While much of the early work in this tradition took its impetus from radical versions of sociology, in the last decade a growing number have utilised the works of the French post-structuralist writer Michel Foucault. My own work in policy analysis, as well as my recent book with John Codd and Anne Marie O’Neill (Olssen, et al., 2004, Sage) presents the outlines of a Foucauldian to the analysis of educational policy and the politics of education. Although there are some aspects of Foucault’s work that are not accepted. – his neutralism over ends and values - there is within Foucault’s work the basis for a broad commitment to a democratic and ethical vision of a new welfare community. Rather than employ him in a one-sided negative way that can be found in some readings of his work, Education Policy seeks to utilise Foucault as an ally, sometimes going beyond the literal canon of his texts, but keeping within his general conception of critique in order to re-articulate and re-theorise a new understanding of a social-democratic polity.
