Diaspora return of transnational migrants to Trinidad and Tobago: the additional contributions of social remittances

Current enthusiasm among development stakeholders for the enticement and recruitment ‘back home’ of skilled Diaspora migrants has predominantly revolved around how human capital gains and transfers of capital, knowledge, technical skills and workplace entrepreneurialism and innovation can be facilitated. In this article, we widen the conceptual basis of this dimension of the migration–development nexus, by bringing the additional contributions of the social remittances that return migrants offer, and practice, into the mix. As evidence, the article examines how and why a sample of ‘middling’1 Trinidadian transnational professionals engage in social development activities and why experiences vary widely on their return. Their views are appraised through the verbal optic of their narratives, which they shared with us during in-depth interviews. Several among these Diaspora returnees appear to be agents for the diffusion and infusion of social capital and non-monetary, social remittances in the homeland to which they have returned in mid-life and mid-career. Others are disappointed, or frustrated, and have their hopes dashed, leading to thoughts of re-migration, or re-return. Despite such difficulties, we find that family belonging and national pride strengthens many of these return migrants’ development potential through their deeply felt commitments to local ‘capacity-building’.

Phosphorus flux from wetland ditch sediments

The accumulation of phosphorus (P) in the bottom sediment of field drainage ditches poses a threat to the ecology both of the ditch water and downstream water courses. We investigated the amounts, forms and internal loading of sediment-bound P along two drainage ditches that regulate water levels in a basin fen (~ 200 ha) supporting a mixture of restored wetland and drained agricultural fields. Water levels in the Lady's Drove Rhyne are currently managed to enhance the biodiversity of the wetland (Catcott Lows Reserve — an area formerly cultivated for arable crop production); whereas, the East Ditch is managed to drain adjoining land that remains under arable and livestock production. Laboratory-based chemical fractionation schemes were used to characterise the forms and potential mobility of the sediment-bound P, whilst pore-water equilibrators were employed in situ to evaluate the diffusive flux of P through the sediment–water column, and to characterise the corresponding redox conditions. Along both ditches, sediment pore-water profiles indicated conditions ranging from weakly to very reducing conditions with increasing depth, and net fluxes of P from the sediment to overlying water. P flux values ranged from 0.33 to 1.30 mg m− 2 day− 1. Both the degree of P saturation (DPS) of the sediment and NaOH extractable (Fe/Al-bound) P correlated significantly (P < 0.05) with P flux. Both in the wetland and agricultural ditches, by far the highest values for P flux were recorded at sites closest to points of drainage water entry from the corresponding, adjoining land. Although the P flux data were obtained from only a single sampling event, this study highlights the contribution of historical as well as ongoing agricultural land use on the sustained elevated P status of ditch sediments in lowland catchments.

Commercial real estate return distributions: a review of literature and empirical evidence

This paper review the literature on the distribution of commercial real estate returns. There is growing evidence that the assumption of normality in returns is not safe. Distributions are found to be peaked, fat-tailed and, tentatively, skewed. There is some evidence of compound distributions and non-linearity. Public traded real estate assets (such as property company or REIT shares) behave in a fashion more similar to other common stocks. However, as in equity markets, it would be unwise to assume normality uncritically. Empirical evidence for UK real estate markets is obtained by applying distribution fitting routines to IPD Monthly Index data for the aggregate index and selected sub-sectors. It is clear that normality is rejected in most cases. It is often argued that observed differences in real estate returns are a measurement issue resulting from appraiser behaviour. However, unsmoothing the series does not assist in modelling returns. A large proportion of returns are close to zero. This would be characteristic of a thinly-traded market where new information arrives infrequently. Analysis of quarterly data suggests that, over longer trading periods, return distributions may conform more closely to those found in other asset markets. These results have implications for the formulation and implementation of a multi-asset portfolio allocation strategy.

The initial return performance of UK property company IPOs

This paper presents empirical evidence for a sample of 48 UK property company initial public offerings over the period 1986 to 1995. From which a number of conclusions can be drawn. First, property companies in general show positive average first day returns. Second, the average first day return by property trading companies is significantly higher than that for property investment companies

The child and imperial return: the mystery of Edwin Drood

The Mystery of Edwin Drood has often been read as an Imperial text, just as Dickens's work has repeatedly been considered in relation to its construction of childhood. Despite this, 'the child' has either been avoided in criticism of Dickens's last novel, or has actively been read as absent. In this essay, I return the ‘repressed’ child to a reading of Drood, and through this disrupt appeals to a hard-impacted Imperial structure I understand to be made within criticism of it.
