(Un)healthy Relationships: African Labourers, Profits and Health Services in Angola’s Colonial-Era Diamond Mines, 1917–75
Authors: Varanda Jorge , Cleveland Todd 
Published: December 2013

AbstractThe Companhia de Diamantes de Angola, or Diamang, mined for diamonds in colonial Angola from 1917 until independence in 1975. The enterprise’s Health Services Division (SSD) was responsible for supplying mine managers with an African labour force comprised of healthy, and therefore productive, employees. In practice, though, this otherwise ‘healthy’ system did not always work. While SSD personnel attempted to fulfil their charge by implementing a series of screening measures, production targets and a scarcely-populated regional labour pool regularly prompted senior officials to compel the SSD to clear recruits who were otherwise unfit for mine service. Drawing upon interviews with former SSD staff and African labourers, as well as company and colonial archival sources, this article focuses on the interplay over time between the SSD, the company’s production demands and these labourers.

Published: December 2013

SUMMARYThe extent to which markers have been used in chickpea breeding programmes has not been clearly determined. In the current study, phenotypic and marker-assisted selection (MAS) were employed to select blight resistant genotypes, comparing the effectiveness of both methods. The phenotypic evaluation showed that the resistance could be recessive in the material employed. However, the high distorted segregation towards the susceptible parent detected on linkage group four (LG4) could also explain the phenotype distribution of resistance. Phenotypic selection in F2:4and F2:5generations lead to an increase in the frequency of the allele associated with the resistance of the markers CaETR and GAA47, indicating the usefulness of these markers for MAS. The markers TA72 and SCY17 could be also useful for MAS but the high distorted segregation towards the susceptible parent in the region where these markers are located could explain their low effectiveness. The costs associated with phenotypic selection and MAS for ascochyta blight resistance during three cycles of selection are presented in the current study, showing that MAS was more expensive than phenotypic selection. Nevertheless, the use of markers reduced the time taken to select resistant lines. The markers analysed in the current study were useful to select genotypes resistant to ascochyta blight in chickpea breeding programmes, allowing pyramiding genes or quantitative trait loci (QTL) related to different pathotypes. It is recommended that MAS should be employed in early generations of chickpea breeding programmes for the four QTL analysed because this makes it possible to develop populations with a high frequency of the favourable alleles conferring resistance to blight.
Durum wheat in-field monitoring and early-yield prediction: assessment of potential use of high resolution satellite imagery in a hilly area of Tuscany, Central Italy

SUMMARYModern agriculture is based on the control of in-field variability, which is determined by the interactions of numerous factors such as soil, climate and crop. For this reason, the use of remote sensing is becoming increasingly important, thanks to the technological development of satellites able to supply information with high spatial resolution and revisit frequency. Despite the large number of studies on the use of remote sensing for crop monitoring, very few have addressed the problem of spatial variability at field scale or the early prediction of crop yield and grain quality. The aim of the current research was to assess the potential use of high resolution satellite imagery for monitoring durum wheat growth and development, addressing forecast grain yield and protein content, through vegetation indices at two stages of crop development. To best represent the natural variability of agricultural production, the study was conducted in wheat fields managed by local farmers. As regards dry weight, leaf area index and nitrogen (N) content, the possibility of describing the crop state is evident at stem elongation, while at anthesis this potential is completely lost. However, satellites seem to be unable to estimate the N concentration. Aboveground biomass accumulated from emergence to stem elongation is strictly related to the final yield, while it has been confirmed that the crop parameters observed at anthesis are less informative, despite approaching harvesting time.
DOES KNOWLEDGE ABOUT ANTIRETROVIRAL THERAPY AND MOTHER-TO-CHILD TRANSMISSION AFFECT THE RELATIONSHIPS BETWEEN HIV STATUS AND FERTILITY PREFERENCES AND CONTRACEPTIVE USE? NEW EVIDENCE FROM NIGERIA AND ZAMBIA

Published: December 2013

SummaryThe increasing availability of antiretroviral therapy (ART) and drug regimens to prevent mother-to-child transmission (PMTCT) has probably changed the context of childbearing for people living with HIV. Using data from 2009–2010 community-based surveys in Nigeria and Zambia, this study explores whether women's knowledge about ART and PMTCT influences the relationship between HIV status and fertility preferences and contraceptive behaviour. The findings show that women living with HIV are more likely to want more children in Nigeria and to want to limit childbearing in Zambia compared with HIV-negative women. While there is no significant difference in contraceptive use by women's HIV status in the two countries, women who did not know their HIV status are less likely to use contraceptives relative to women who are HIV-negative. Knowledge about ART reduces the childbearing desires of HIV-positive women in Nigeria and knowledge about PMTCT increases desire for more children among HIV-positive women in Zambia, as well as contraceptive use among women who do not know their HIV status. The findings indicate that knowledge about HIV prevention and treatment services changes how living with HIV affects childbearing desires and, at least in Zambia, pregnancy prevention, and highlight the importance of access to accurate knowledge about ART and PMTCT services to assist women and men to make informed childbearing decisions. Knowledge about ART and PMTCT should be promoted not only through HIV treatment and maternal and newborn care facilities but also through family planning centres and the mass media.
A non-overconstrained variant of the Agile Eye with a special decoupled kinematics
Authors: Kuo Chin-Hsing , Dai Jian S. , Legnani Giovanni 
Published: December 2013

SUMMARYA non-overconstrained three-DOF parallel orientation mechanism that is kinematically equivalent to the Agile Eye is presented in this paper. The output link (end-effector) of the mechanism is connected to the base by one spherical joint and by another three identical legs. Each leg comprises of, in turns from base, a revolute joint, a universal joint, and three prismatic joints. The three lower revolute joints are active joints, while all other joints are passive ones. Based on a special configuration, some three projective angles of the end-effector coordinates are fully decoupled with respect to the input actuated joints, that is, by actuating any revolute joint the end-effector rotates in such a way that the corresponding projective angle changes with the same angular displacement. The fully decoupled motion is analyzed geometrically and proved theoretically. Besides, the inverse and direct kinematics solutions of the mechanism are provided based on the geometric reasoning and theoretical proof.
Forced Saving in China
Authors: Eckaus Richard S. 
Published: December 2013

AbstractThe explanation offered here for the high rates of saving in China is that much of the saving has been “forced” in two Benthamite senses. Involuntary saving, the first of Bentham's meanings, includes taxes which finance investment. These have made up more than half of the total savings in China in recent years. There is also forced saving in China in the form of Bentham's second sense, conduced saving, resulting from bank loans which have financed investment. While the existence of a savings glut has been suggested for China, a better characterization would be that it has had a high rate of investment.
Using discards not destined for human consumption
Authors: MANGI STEPHEN C , CATCHPOLE THOMAS L. 
Published: December 2013

SUMMARYThe Common Fisheries Policy (CFP) reforms agreed by European Union (EU) ministers include a discard ban where fishers will be required to land all fish they catch. The ban is expected to reduce the risk of capturing unwanted and low-value biomass species, and therefore should make fishing more environmentally and economically sustainable. The implications of introducing a discards ban may be gauged by assessing the practical and economic issues surrounding whether discards not destined for human consumption can be used once landed. Interviews with company managers established the attitude of the main commercial outlets towards suitability of, and interest in using discards. Results indicate that opportunities for using discards include reduction to fishmeal and fish oil, ensiling, composting, anaerobic digestion with energy recovery, and freezing (prior to use as bait). In the UK, nine main outlets expressed interest in using discards as raw materials to process into animal, pet and aqua feed; organic fertilizer; frozen bait; and other products, such as renewable energy generation. Estimates of discard quantities from English fleets show that most of the outlets are not located close to the main landing ports where the discards would likely come ashore. However, most outlets have extensive established transport links, which would enable them to cover even the remote ports. Preliminary analysis on cost of discarding shows that a discard ban will lead to increases in annual operating costs for fishers ranging from GB£ 1709–90 959 yr−1 (£1 = US$ 1.52, May 2013). Assuming that discards are processed for fishmeal, fetching c. GB£ 130 t−1, then majority of the fishers will make losses in their fishing operations. Such losses could lead fishers to adopt more selective gears in order to avoid catching unwanted species and thereby help conserve the marine environment. Finding potential uses for discards is important in the context of the proposed land-all catch policy under the reformed CFP, but the primary goal of government should be to prevent the capture of unwanted fish.
Development without Decolonisation? Hong Kong's Future and Relations with Britain and China, 1967–1972
Authors: MARK CHI-KWAN 
Published: December 2013

AbstractAt a time when the United Kingdom accelerated decolonisation and slowly embraced Europe, London gradually lost the means and the will to fulfil its responsibilities to Hong Kong up until the expiry of the New Territories Lease in 1997. Although the immediate cause of this pessimistic mind-set was the leftist riots in 1967, the factors underlying despondency in London had to do with developments before 1967, namely Hong Kong's growing economic prosperity and administrative autonomy from London since the late 1950s, and beyond Hong Kong itself, the global implications of Britain's withdrawal from East of Suez and entry into the European Economic Community by the early 1970s. By 1972 the process of the “decolonisation” of Hong Kong was well underway. Although the British deemed the time unsuitable to initiate formal negotiation with the then Chinese government, they were prepared to take “informal soundings” concerning Hong Kong's future when a new pragmatic leadership emerged and before the crisis of confidence ensued nearer 1997.
Legal fictions and the limits of legal language
Authors: Petroski Karen 
Published: December 2013

AbstractSince Lon Fuller published his 1930 trilogy of essays on the topic, students of the legal fiction have focused on identifying additional examples of fictions or challenging Fuller's classic taxonomy. But Fuller did more in these essays than propose a definition and a classification system; he also argued that legal fictions are examples of a more general phenomenon found in many systems of specialised language usage. Drawing on work done in the intervening decades on related issues outside the law, this paper develops this insight in new directions, seeking to understand in more detail one of Fuller's principal concerns: the points at which legal language stops communicating, points that may shift over time but will never completely disappear. The analysis indicates that the currently prevailing understanding of legal fictions as, in essence, consciously counterfactual propositions is historically contingent and incomplete; that legal writers have generally used the ‘legal fiction’ label to signal those writers' sense of the futility of further justification to a non-legal audience (even when they are using the term in a justification likely to be read only by a legal audience); and, contrary to the assumptions of many post-Fuller theorists, that the boundaries of the legal vocabularies recognised as self-justifying may have become less distinct over the past century.
Cost drivers of inpatient mental health care: a systematic review
Authors: Wolff J. , McCrone P. , Koeser L. , Normann C. , Patel A. 
Published: December 2013

Aims.New reimbursement schemes for inpatient mental health care are imminent in the UK and Germany. The shared intention is to reflect cost differences between patients in reimbursement rates. This requires understanding of patient characteristics that influence hospital resource use. The aim of this review was to show which associations between mental health care per diem hospital costs and patient characteristics are supported by current evidence.Methods.A systematic review of the literature published between 1980 and 2012 was carried out. The search strategy included electronic databases and hand-searching. Furthermore, reference lists, citing articles and related publications were screened and experts were contacted.Results.The search found eight studies. Dispersion in per diem costs was moderate, as was the ability to explain it with patient characteristics. Six patient characteristics were identified as the most relevant variables. These were (1) age, (2) major diagnostic group, (3) risk, (4) legal problems, (5) the ability to perform activities of daily living and (6) presence of psychotic or affective symptoms. Two non-patient-related factors were identified. These were (1) day of stay and (2) treatment site.Conclusions.Idiosyncrasies of mental health care complicated the prediction of per diem hospital costs. More research is required in European settings since transferability of results is unlikely.

Published: December 2013

AbstractThe objective of this study was to verify the factor validity and structure of the “Irritation Scale” in a sample of 578 Spanish university students. At the same time, the study aimed to verify the criterion-related validity of the scale, analyzing the results obtained through correlation with other variables, such as general self-efficacy, self-regulation, depression, and certain personality dimensions. The results obtained through the Exploratory Structural Equation Modeling approach (ESEM) using Mplus confirmed the presence of two factors in the Irritation Scale, as observed in other international studies within a workplace setting. The significant correlations obtained between the Irritation Scale and the variables considered in the study confirmed the construct validity and verified that irritation is significantly and positively associated with depression and academic burnout, and is negatively associated with general self-efficacy and self-regulation.
When the Care Ends: Emotional State of Spanish Bereaved Caregivers of Persons with Dementia

Published: December 2013

AbstractSeveral researchers have found that caring for relatives with dementia has negative consequences on the caregiver’s physical and emotional health during the caregiving period. However, less attention has been paid to caregiver´s emotional state after the patient´s death. The aims of this study are 1) to evaluate the emotional state of the Spanish former caregivers after the care recipient death, and 2) to analyze the patient’s death circumstances and their influence in the current emotional state of caregivers. The sample was composed of 50 former caregivers of relatives diagnosed with Alzheimer’s disease. The dependent variables were assessed using the Beck Depression Inventory and the Texas Revised Inventory of Grief. Most of the caregivers did not develop a complicated grief or depressive symptoms. However, caregivers are not uniform in their responses to bereavement. Specifically, grief was higher in spouses than in adult child, even after controlling the effect of gender and age. Furthermore, this study provides first evidence of the positive relationship between saying good-bye to the patient and caregivers’ emotional status.
Highly Stable Wideband Microwave Extraction by Synchronizing Widely Tunable Optoelectronic Oscillator with Optical Frequency Comb

Published: December 2013

AbstractOptical frequency combs (OFCs), based on mode-locked lasers (MLLs), have attracted considerable attention in many fields over recent years. Among the applications of OFCs, one of the most challenging works is the extraction of a highly stable microwave with low phase noise. Many synchronisation schemes have been exploited to synchronise an electronic oscillator with the pulse train from a MLL, helping to extract an ultra-stable microwave. Here, we demonstrate novel wideband microwave extraction from a stable OFC by synchronising a single widely tunable optoelectronic oscillator (OEO) with an OFC at different harmonic frequencies, using an optical phase detection technique. The tunable range of the proposed microwave extraction extends from 2 GHz to 4 GHz and in a long-term synchronisation experiment over 12 hours, the proposed synchronisation scheme provided a rms timing drift of 18 fs and frequency instabilities at 1.2 × 10−15/1 s and 2.2 × 10−18/10000 s.
Enhancing the peroxidase activity of cytochrome c by mutation of residue 41: implications for the peroxidase mechanism and cytochrome c release
Authors: Josephs Tracy M. , Morison Ian M. , Day Catherine L. , Wilbanks Sigurd M. , Ledgerwood Elizabeth C. 
Published: December 2013

The peroxidase activity of cytochrome c may play a key role in the release of cytochrome c from the mitochondrial intermembrane space in the intrinsic apoptosis pathway. Induction of the peroxidase activity of cytochrome c is ascribed to partial unfolding and loss of axial co-ordination between the haem Fe and Met80, and is thought to be triggered by interaction of cytochrome c with cardiolipin (diphosphatidylglycerol) in vivo. However, the reaction mechanism for the peroxidase activity of either native or cardiolipin-bound cytochrome c is uncertain. In the present study we analyse the peroxidase activity of human and mouse cytochrome c residue 41 variants and demonstrate that stimulation of peroxidase activity can occur without prior loss of Fe–Met80 co-ordination or partial unfolding. The effects of cardiolipin and mutation of residue 41 are not additive, suggesting that cardiolipin stimulates peroxidase activity by the same mechanism as residue 41 mutation. Consistent with this, mutation of residue 41 did not enhance apoptotic release of cytochrome c from mitochondria. We propose that mutation of residue 41, and interaction with cardiolipin, increase peroxidase activity by altering the 40–57 Ω loop and its hydrogen bond network with the propionate of haem ring A. These changes enhance access of hydrogen peroxide and substrate to the haem.
Mid-infrared InAs0.79Sb0.21-based nBn photodetectors with Al0.9Ga0.2As0.1Sb0.9 barrier layers, and comparisons with InAs0.87Sb0.13 p-i-n diodes, both grown on GaAs using interfacial misfit arrays

InAs0.79Sb0.21-based nBn photodetectors were fabricated on a GaAs substrate, using the interfacial misfit array growth mode. Reductions in the dark current density of more than two orders of magnitude at 300 K and more than six orders of magnitude at 200 K were found, in comparison with an InAs0.87Sb0.13 p-i-n diode. At −0.5 V applied bias, the dark currents were found to be diffusion limited above 150 K. Background limited infrared photodetection and R0A values in excess of 106 Ωcm2 were observed at 150 K. Spectral response measurements revealed a cut-off wavelength of 5.3 μm at 200 K.
Dangerous Women: Observations on the Feast of Herod in Florentine Art of the Early Renaissance
Authors: Long Jane C. 
Published: December 2013

AbstractThis article investigates four widely studied versions of the biblical story of the Feast of Herod produced by Florentine artists in the fourteenth and fifteenth centuries: Giotto’s fresco from the Peruzzi Chapel at Santa Croce (ca. 1320), Andrea Pisano’s panels on the south doors of Florence’s baptistery (ca. 1335), Donatello’s relief for the baptismal font at Siena (ca. 1425), and Filippo Lippi’s fresco in the main chapel at the cathedral of Prato (ca. 1465). The study explores how the narrative is interpreted by each artist and suggests social messages that contemporary audiences might have drawn from each interpretation by examining the actions of the figures in light of the teachings of late medieval and early Renaissance didactic literature. Conduct literature allows one to interpret what the works reveal about the story, but also suggests that they could function didactically, in and of themselves. In such a reading, Herodias and Salome are treacherous women: dangerous not only to John the Baptist, but also to Florentine society of the period.
Generating Skilled Self-Employment in Developing Countries: Experimental Evidence from Uganda
*
Authors: Blattman Christopher , Fiala Nathan , Martinez Sebastian 
Published: December 2013

Abstract
We study a government program in Uganda designed to help the poor and unemployed become self-employed artisans, increase incomes, and thus promote social stability. Young adults in Uganda’s conflict-affected north were invited to form groups and submit grant proposals for vocational training and business start-up. Funding was randomly assigned among screened and eligible groups. Treatment groups received unsupervised grants of $382 per member. Grant recipients invest some in skills training but most in tools and materials. After four years, half practice a skilled trade. Relative to the control group, the program increases business assets by 57%, work hours by 17%, and earnings by 38%. Many also formalize their enterprises and hire labor. We see no effect, however, on social cohesion, antisocial behavior, or protest. Effects are similar by gender but are qualitatively different for women because they begin poorer (meaning the impact is larger relative to their starting point) and because women’s work and earnings stagnate without the program but take off with it. The patterns we observe are consistent with credit constraints.
