Interpreting mega-development projects as territorial traps: the case of irrigation schemes on the shores of Lake Chad (Borno State, Nigeria)

From the colonial era up to the present, mega-irrigation projects for agriculture have played a key role in the production of state space in Sahelian Africa. Transferring a concept proposed by Agnew (1994) onto a different scale, it is possible to interpret these mega-projects as \u201cterritorial traps\u201d. In fact, they set up boundaries (physical, relational, cognitive and operative) that force evolutive trajectories of the areas involved along rigid pathways. In the aftermath of the systematic failure of the mega-projects, farmers are faced with constraints determined by the trap imposed, without having any of the promised benefits in terms of productive growth, i.e. income. In many situations, the farmers have identified \u201ca means of escape\u201d from these catastrophes by transgressing the boundaries imposed by the territorial traps and reintroducing parts of the infrastructure to a common use. The case study presented regards the irrigation mega-projects on the shores of Lake Chad, in Nigeria

Poverty and aspirations failure

We develop a model of internal constraints to show that a greater degree of initial disadvantage results in a higher likelihood of low aspirations and low achievement. Our model and results are supported by evidence from anthropology, sociology and social psychology. Our analysis suggests that internal constraints are a key ingredient in perpetuating poverty traps. We show that a poor person will choose to restrict her cognitive window (the set of other individuals who are her role models) and study the conditions under which a role model could alter her aspirations and achievement. We show how enodgenously chosen cognitive windows interact with the inital distribution of status to determine whether or not a society is connected, and hence the transmission of aspirations across individuals in that society. Our work provides a normative justification for programs that aim at empowering disadvantaged individuals by directly shocking their aspirations

Identity Traps or How Black Students Fail: the interactions between biographical, sub-cultural, and learner identities

The enduring inequities experienced by African-Caribbean students in UK schools has been well documented. This paper aims to better understand how these inequities have come to be so enduring. Through detailed analyses of data generated through a school ethnography, this paper demonstrates the processes through which African-Caribbean students are identified as undesirable, or even intolerable, learners. The paper builds on the insights offered by earlier school ethnographies while deploying and developing a new theoretical framework. This framework suggests that the discursive practices of students and teachers contribute to the performative constitution of intelligible selves and others. Drawing on this framework, the paper demonstrates how African-Caribbean race and sub-cultural identities, and further intersecting biographical identities including gender and sexuality, are deployed within organisational discourse as evidence of these students? undesirable learner identities

Use of flight interception traps of Malaise type and attractive traps for social wasps record (Vespidae: Polistinae)

The literature provides different methodologies for sampling social wasps, including, flight intercept trap type Malaise and Attractive trap, however, there is no consensus on its use. In this respect, the aim of this study was to evaluate the best use of Malaise traps and Attractive trap in biodiversity work of social wasps, and generate a collection protocol for the use of these traps. The study was conducted in the Parque Estadual do Rio Doce, located in the east of the state of Minas Gerais, in the years 2000, 2001, 2002 and 2004 and in the Botanical Garden of the Federal University of Juiz de Fora, located in the southeastern state of Minas Gerais, in years 2011, 2012 and 2013. 15 species were collected using Malaise traps, and, 26 species of social wasps were collected using Attractive traps. Although the negative aspects of both traps, complementary methodologies surveys varying social wasps are useful and it is recommended to choose for using in accordance with the logistical field

Inequality and higher education: marketplace or social justice?

Professor Hall’s paper addresses the key social issues of poverty and inequality of educational opportunity, comparing the UK’s policy history and experience with that of South Africa and identifying the important roles that higher education leaders at institutional and system levels can play. Professor Hall’s paper is accompanied by a short commentary from six higher education leaders who all have a strong track-record of addressing the issues that Professor Hall’s paper raises

Phenology of the Diamondback moth (Plutella xylostella) in the UK and provision of decision support for brassica growers

In the UK, severe infestations by Plutella xylostella occur sporadically and are due mainly to the immigration of moths. The aim of this study was to develop a more detailed understanding of the phenology of P. xylostella in the UK and investigate methods of monitoring moth activity, with the aim of providing warnings to growers. Plutella xylostella was monitored using pheromone traps, by counting immature stages on plants, and by accessing citizen science data (records of sightings of moths) from websites and Twitter. The likely origin of migrant moths was investigated by analysing historical weather data. The study confirmed that P. xylostella is a sporadic but important pest, and that very large numbers of moths can arrive suddenly, most often in early summer. Their immediate sources are countries in the western part of continental Europe. A network of pheromone traps, each containing a small camera sending images to a website, to monitor P. xylostella remotely provided accessible and timely information, but the particular system tested did not appear to catch many moths. In another approach, sightings by citizen scientists were summarised on a web page. These were accessed regularly by growers and, at present, this approach appears to be the most effective way of providing timely warnings

End of a Faustian pact: Workfare and riots

During the past three decades, politicians struck a Faustian pact. In return for ‘labour market flexibility’, government would top up declining wages through subsidies and tax credits and redirect social protection from an emphasis on social solidarity and social insurance to means-tested social assistance. In the aftermath of rioting, they must now face the following fact: it is the economic policies they have supported that are a major cause of the underlying malaise. If they do not, they will find themselves acceding to an increasingly coercive and punitive social policy, epitomised by workfare and the vogue term of ‘conditional welfare’. Politicians must step back from the utilitarian direction in which they have taken us during the past thirty years and consider an alternative road

From Little Words, Big Words Grow: Annotations on the Yo, Sí Puedo Experience in Brewarrina, Australia

This article is a reflection on the application of the Cuban literacy methodology Yo, Sí Puedo to the Australian setting. The Yo, Sí Puedo / Yes, I Can! model developed in Cuba by the Instituto Pedagógico Latinoamericano y Caribeño, IPLAC (Institute of Pedagogy for Latin America and the Caribbean) has been successfully implemented across the Global South as a strategy of adult literacy. It is a legacy of our Latin American revolutionary roots, with its origin in the Freirean pedagogy of the oppressed. Expanding across continents this model continues to teach reading and writing to disenfranchised adults in marginal and Indigenous communities, from the Argentinean Chaco to Brewarrina in northern NSW, Australia. Its aim is to contribute to the hope of improving the health and educational outcomes of the country’s First Peoples. This article is indebted to conversations with the Cuban advisor of Yes, I Can!, José Manuel Chala Leblanch. Observing him working in the classroom setting of Brewarrina touched me at different levels: personally because it reminded me of my own family experiences with the education system in my country, Argentina; and professionally as an educator negotiating different languages and cultures. It also reinforced my belief in the importance of incorporating Indigenous ways of learning and teaching to Western styles of teaching and learning. I built this reflection moving from personal and poetic—visual and textual—narratives and observations to academic interventions informed by researched literature on adult and Indigenous education

Baseline and stress-induced levels of corticosterone in male and female Afrotropical and European temperate stonechats during breeding

Background: Latitudinal variation in avian life histories falls along a slow-fast pace of life continuum: tropical species produce small clutches, but have a high survival probability, while in temperate species the opposite pattern is found. This study investigated whether differential investment into reproduction and survival of tropical and temperate species is paralleled by differences in the secretion of the vertebrate hormone corticosterone (CORT). Depending on circulating concentrations, CORT can both act as a metabolic (low to medium levels) and a stress hormone (high levels) and, thereby, influence reproductive decisions. Baseline and stress-induced CORT was measured across sequential stages of the breeding season in males and females of closely related taxa of stonechats (Saxicola spp) from a wide distribution area. We compared stonechats from 13 sites, representing Canary Islands, European temperate and East African tropical areas. Stonechats are highly seasonal breeders at all these sites, but vary between tropical and temperate regions with regard to reproductive investment and presumably also survival. Results: In accordance with life-history theory, during parental stages, post-capture (baseline) CORT was overall lower in tropical than in temperate stonechats. However, during mating stages, tropical males had elevated post-capture (baseline) CORT concentrations, which did not differ from those of temperate males. Female and male mates of a pair showed correlated levels of post-capture CORT when sampled after simulated territorial intrusions. In contrast to the hypothesis that species with low reproduction and high annual survival should be more risk-sensitive, tropical stonechats had lower stress-induced CORT concentrations than temperate stonechats. We also found relatively high post-capture (baseline) and stress-induced CORT concentrations, in slow-paced Canary Islands stonechats. Conclusions: Our data support and refine the view that baseline CORT facilitates energetically demanding activities in males and females and reflects investment into reproduction. Low parental workload was associated with lower post-capture (baseline) CORT as expected for a slow pace of life in tropical species. On a finer resolution, however, this tropical-temperate contrast did not generally hold. Post-capture (baseline) CORT was higher during mating stages in particular in tropical males, possibly to support the energetic needs of mate-guarding. Counter to predictions based on life history theory, our data do not confirm the hypothesis that long-lived tropical populations have higher stress-induced CORT concentrations than short-lived temperate populations. Instead, in the predator-rich tropical environments of African stonechats, a dampened stress response during parental stages may increase survival probabilities of young. Overall our data further support an association between life history and baseline CORT, but challenge the role of stress-induced CORT as a mediator of tropical-temperate variation in life history
