How efficient is the European football betting market? Evidence from arbitrage and trading strategies
Authors: Vlastakis Nikolaos , Dotsis George , Markellos Raphael N. 
Published: November 2008

AbstractThis paper assesses the international efficiency of the European football betting market by examining the forecastability of match outcomes on the basis of the information contained in different sets of online and fixed odds quoted by six major bookmakers. The paper also investigates the profitability of strategies based on: combined betting, simple heuristic rules, regression models and prediction encompassing. The empirical results show that combined betting across different bookmakers can lead to limited but highly profitable arbitrage opportunities. Simple trading rules and betting strategies based on forecast encompassing are found capable of also producing significant positive returns. Despite the deregulation, globalization and increased competition in the betting industry over recent years, the predictabilities and profits reported in this paper are not fully consistent with weak‐form market efficiency. Copyright © 2008 John Wiley & Sons, Ltd.
Modelling blue and green water resources availability in Iran
Authors: Faramarzi Monireh , Abbaspour Karim C. , Schulin Rainer , Yang Hong 
Published: November 2008

AbstractKnowledge of the internal renewable water resources of a country is strategic information which is needed for long‐term planning of a nation's water and food security, among many other needs. New modelling tools allow this quantification with high spatial and temporal resolution. In this study we used the program Soil and Water Assessment Tool (SWAT) in combination with the Sequential Uncertainty Fitting program (SUFI‐2) to calibrate and validate a hydrologic model of Iran based on river discharges and wheat yield, taking into consideration dam operations and irrigation practices. Uncertainty analyses were also performed to assess the model performance. The results were quite satisfactory for most of the rivers across the country. We quantified all components of the water balance including blue water flow (water yield plus deep aquifer recharge), green water flow (actual and potential evapotranspiration) and green water storage (soil moisture) at sub‐basin level with monthly time‐steps. The spatially aggregated water resources and simulated yield compared well with the existing data. The study period was 1990–2002 for calibration and 1980–1989 for validation. The results show that irrigation practices have a significant impact on the water balances of the provinces with irrigated agriculture. Concerning the staple food crop in the country, 55% of irrigated wheat and 57% of rain‐fed wheat are produced every year in water‐scarce regions. The vulnerable situation of water resources availability has serious implications for the country's food security, and the looming impact of climate change could only worsen the situation. This study provides a strong basis for further studies concerning the water and food security and the water resources management strategies in the country and a unified approach for the analysis of blue and green water in other arid and semi‐arid countries.

Opportunity to recycle chromium(VI) by in situ electro‐oxidation
Authors: Lateef Huma , Grimes Susan M , Chaudhary Abdul J , Goswami Nimai C 
Published: November 2008

AbstractBACKGROUND: Chemical oxidation is generally used to oxidise Cr(III) to Cr(VI) in aqueous effluents, but this leads to Cr(VI) solutions that are contaminated with oxidising agents, which reduces their recycle and reuse value.RESULTS: We now report an electrolytic method for the in situ oxidation of Cr(III). Complete oxidation of Cr(III) occurs anodically using an initial pH of 5.0 and a current of 3.0 A.CONCLUSIONS: Anodic oxidation is shown to achieve in situ oxidation of Cr(III) to Cr(VI) to permit the regeneration of Cr(VI) solutions for recycle in oxidising industrial processes.

The ‘reversal of fortune’ thesis and the compression of history: Perspectives from African and comparative economic history
Authors: Austin Gareth 
Published: November 2008

AbstractAcemoglu, Johnson and Robinson have dramatically challenged the tendency of economists to confine their empirical search for the causes of economic growth to the recent past. They argue that the kind of institutions established by European colonialists,eitherprotecting private propertyorextracting rents, resulted in the poorer parts of the pre‐colonial world becoming some of the richest economies of today; while transforming some of the more prosperous parts of the non‐European world of 1500 into the poorest economies today. This view has been further elaborated for Africa by Nunn, with reference to slave trading. Drawing on African and comparative economic historiography, the present paper endorses the importance of examining growth theories against long‐term history: revealing relationships that recur because the situations are similar, as well as because of path dependence as such. But it also argues that the causal relationships involved are more differentiated than is recognised in AJR's formulations. By compressing different historical periods and paths, the ‘reversal’ thesis over‐simplifies the causation. Relatively low labour productivity was a premise of the external slave trades; though the latter greatly reinforced the relative poverty of many Sub‐Saharan economies. Again, it is important to distinguish settler and non‐settler economieswithincolonial Africa itself. In the latter case it was in the interests of colonial regimes to support, rather than simply extract from, African economic enterprise. Finally, economic rent and economic growth have often been joint products, including in pre‐colonial and colonial Africa; the kinds of institutions that favoured economic growth in certain historical contexts were not necessarily optimal for that purpose in others. AJR have done much to bring development economics and economic history together. The next step is a more flexible conceptual framework, and a more complex explanation.

Measuring and explaining poverty in six African countries: A long‐period approach
Authors: Bowden Sue , Chiripanhura Blessing , Mosley Paul 
Published: November 2008

AbstractIn this paper, we create the beginnings of a database on indicators of poverty and deprivation in six African countries over the last 100 years, with the intention of explaining the long‐term trend of policy. We argue that an important key to those trends is provided by the decision during the first decades of the twentieth century to allow, or not to allow, the occupation of agricultural land by European settlers. If allowed (as in the white settler—controlled economies of South Africa, Zimbabwe and Kenya, where Africans were squeezed out of income‐earning opportunities by competition and prohibition until the 1960s at least) the legacy, we show, was a lack of bargaining power by Africans in the labour market, a real wage static at the subsistence level until late in the century, a highly unequal income distribution, and a small asset base from which to reduce poverty during the liberalisations of the 1980s and 1990s. If forbidden, as in the peasant‐export economies of Ghana and Uganda (and to some extent Ethiopia), the legacy was a floor under the labour market, from the 1920s on, which could serve as a basis for poverty‐reducing reforms in later years. Thus the potential for poverty reduction during the current ‘poverty reduction wave’ was indeed determined by the historical inheritance of institutions and policies, in particular settlement policies; but in a quite different way from that adumbrated by the recent analysis of Acemoglu et al. (2001). In their analysis, colonies with a high density of European occupation in colonial times persistently generate higher growth potential in later years; we argue the reverse.

A laboratory‐based study of understanding of uncertainty in 5‐day site‐specific temperature forecasts
Authors: Roulston Mark S. , Kaplan Todd R. 
Published: November 2008

AbstractThe impact of presenting uncertainty in 5‐day location‐specific temperature forecasts on the decision making of non‐specialists was tested in an experimental economics laboratory. Undergraduate students studying a range of disciplines were asked to select which of two criteria involving temperature would be most likely to occur based on a given 5‐day forecast. If they selected a criterion that was subsequently satisfied they were given a small cash reward. It was found that students presented with uncertainty information (the 50th and 90th percentile confidence intervals) in addition to the expected temperature were more likely to select the most probable criterion. This was true irrespective of the academic subject the participants were studying. Copyright © Royal Meteorological Society and Crown Copyright, 2008
Observations on the relationship between lake formation, permafrost activity and lithalsa development during the last 20 000 years in the Tso Kar basin, Ladakh, India
Authors: Wünnemann Bernd , Reinhardt Christian , Kotlia Bahadur S. , Riedel Frank 
Published: November 2008

AbstractA close relationship has existed between high mountain permafrost and lake history in the Tso Kar basin, Ladakh, India throughout the last 20 kyr BP. Analyses of sediment cores indicate phases of permafrost growth during low lake levels between >20–10 cal. kyr BP and after 5 cal. kyr BP. Palaeo‐shorelines and lake carbonate outcrops indicate a maximum lake size at ca. 8–5 cal. kyr BP when permafrost is believed to have been absent in the basin. Regression of the lake with accompanying salinisation since about 4 cal. kyr BP allowed permafrost aggradation. Permafrost mounds and thermokarst features are inferred to have continued to develop in the last 60 years. Sections in two 6–10 m high unvegetated mounds revealed thick ice lenses and reticulate cryostructures leading to their classification as lithalsas. Mound collapse is induced by surface erosion and slumping, while sediment reworking by wave action and other processes appears to prevent rampart formation. If lake levels continue to fall, further permafrost aggradation is expected in this high elevation enclosed basin. Copyright © 2008 John Wiley & Sons, Ltd.
Towards generic representation of web applications: solutions and trade‐offs
Authors: Rajapakse Damith C. , Jarzabek Stan 
Published: November 2008

AbstractServer pages (also called dynamic pages) render a generic web page into many similar ones. The technique is commonly used for implementing web application user interfaces (UIs). Yet our previous study found a high rate of repetitions (also called ‘clones’) in web applications, particularly in UIs. The finding raised the question as to why such repetitions had not been averted with the use of server pages. For an answer, we conducted an experiment using PHP server pages to explore how far server pages can be pushed to achieve generic web applications. Our initial findings suggested that generic representation obtained using server pages sometimes compromises certain important system qualities such as run‐time performance. It may also complicate the use of WYSIWYG editors. We have analysed the nature of these trade‐offs, and now propose amixed‐strategyapproach to obtain optimum generic representation of web applications without unnecessary compromise to critical system qualities and user experience. The mixed‐strategy approach applies the generative technique of XVCL to achieve genericity at the meta‐level representation of a web application, leaving repetitions to the actual web application. Our experiments show that the mixed‐strategy approach can achieve a good level of genericity without conflicting with other system qualities. Our findings should open the way for others to better‐informed decisions regarding generic design solutions, which should in turn lead to simpler, more maintainable and more reusable web applications.

RFID sensors based on ubiquitous passive 13.56‐MHz RFID tags and complex impedance detection
Authors: Potyrailo Radislav A. , Morris William G. , Sivavec Timothy , Tomlinson Harold W. , Klensmeden Staffan , Lindh Kenneth 
Published: November 2008

AbstractPassive radio frequency identification (RFID) sensors are attractive in diverse applications where sensor performance is needed at a low cost and when battery‐free operation is critical. We developed a general approach for adapting ubiquitous and cost‐effective passive 13.56‐MHz RFID tags for diverse sensing applications. In developed RFID sensors, the complex impedance of the RFID resonant antenna is measured and correlated to physical, chemical, or biological properties of interest. In contrast to known wireless sensors, developed RFID sensors combine several measured parameters from the resonant sensor antenna with multivariate data analysis and deliver unique capability for multianalyte sensing and rejection of environmental interferences with a single sensor. Theoretical calculations and experiments in an anechoic chamber demonstrate that the developed RFID sensors are immune to common electromagnetic interferences and the sensor/reader system operates within regulated emission levels. Performance of developed RFID sensors is illustrated in measurements of toxic industrial chemicals (TICs) in air with the detection limit (DL) of 80 parts per billion and in a non‐invasive monitoring of milk spoilage. Sensors selectivity is demonstrated in the detection of different vapors with individual sensors. Copyright © 2008 John Wiley & Sons, Ltd.
Synchrony of spatial populations: heterogeneous population dynamics and reddened environmental noise
Authors: Liu Zhiguang , Gao Meng , Li Zizhen , Zhu Gaofeng 
Published: November 2008

AbstractMany species exhibit widespread spatial synchrony in population fluctuations. This pattern is of great ecological interest and can be a source of concern when a species is rare or endangered. Moran's theorem suggests that if two (or more) populations sharing a common linear density‐dependence in the renewal process are disturbed with correlated noise, they will become synchronized with correlation matching the noise correlation. In this report, correlation of nonidentical populations that are described by linear and stationary autoregressive processes is analyzed. We show that the expected spatial synchrony between two populations can be decomposed into two multiplicative components. One is the demographic component related to the values of the autoregressive coefficients and the noise color. The other is the spatial correlation of the environmental colored noise. The main results are consistent with the predictions of previous experiments and simulations, and the importance of this report is to provide theoretical support.
The Vertical Structure of Warm Ionised Gas in the Milky Way
Authors: Gaensler B. M. , Madsen G. J. , Chatterjee S. , Mao S. A. 
Published: November 2008

AbstractWe present a new joint analysis of pulsar dispersion measures and diffuse Hα emission in the Milky Way, which we use to derive the density, pressure and filling factor of the thick disk component of the warm ionised medium (WIM) as a function of height above the Galactic disk. By excluding sightlines at low Galactic latitude that are contaminated by Hii regions and spiral arms, we find that the exponential scale-height of free electrons in the diffuse WIM is 1830–250+120 pc, a factor of two larger than has been derived in previous studies. The corresponding inconsistent scale heights for dispersion measure and emission measure imply that the vertical profiles of mass and pressure in the WIM are decoupled, and that the filling factor of WIM clouds is a geometric response to the competing environmental influences of thermal and non-thermal processes. Extrapolating the properties of the thick-disk WIM to mid-plane, we infer a volume-averaged electron density 0.014 ± 0.001 cm−3, produced by clouds of typical electron density 0.34 ± 0.06 cm−3 with a volume filling factor 0.04 ± 0.01. As one moves off the plane, the filling factor increases to a maximum of ∼30% at a height of ≈1–1.5 kpc, before then declining to accommodate the increasing presence of hot, coronal gas. Since models for the WIM with a ≈1 kpc scale-height have been widely used to estimate distances to radio pulsars, our revised parameters suggest that the distances to many high-latitude pulsars have been substantially underestimated.
InPSR26, a Putative Membrane Protein, Regulates Programmed Cell Death during Petal Senescence in Japanese Morning Glory

Published: November 2008

Abstract
The onset and progression of petal senescence, which is a type of programmed cell death (PCD), are highly regulated. Genes showing changes in expression during petal senescence in Japanese morning glory (Ipomoea nil) were isolated and examined to elucidate their function in PCD. We show here that a putative membrane protein, InPSR26, regulates progression of PCD during petal senescence in Japanese morning glory. InPSR26 is dominantly expressed in petal limbs and its transcript level increases prior to visible senescence symptoms. Transgenic plants with reduced InPSR26 expression (PSR26r lines) showed accelerated petal wilting, with PCD symptoms including cell collapse, ion and anthocyanin leakage, and DNA degradation accelerated in petals compared to wild-type plants. Transcript levels of autophagy- and PCD-related genes (InATG4, InATG8, InVPE, and InBI-1) were reduced in the petals of PSR26r plants. Autophagy visualized by monodansylcadaverine staining confirmed that autophagy is induced in senescing petal cells of wild-type plants and that the percentage of cells containing monodansylcadaverine-stained structures, most likely autophagosomes, was significantly lower in the petals of PSR26r plants, indicating reduced autophagic activity in the PSR26r plants. These results suggest that InPSR26 acts to delay the progression of PCD during petal senescence, possibly through regulation of the autophagic process. Our data also suggest that autophagy delays PCD in petal senescence.

AbstractRoot hairs are single tubular cells formed from the differentiation of epidermal cells on roots. They are involved in water and nutrient uptake and represent the infection site on leguminous roots by rhizobia, soil bacteria that establish a nitrogen-fixing symbiosis. Root hairs develop by polar cell expansion or tip growth, a unique mode of plant growth shared only with pollen tubes. A more complete characterization of root hair cell biology will lead to a better understanding of tip growth, the rhizobial infection process, and also lead to improvements in plant water and nutrient uptake. We analyzed the proteome of isolated soybean (Glycine max) root hair cells using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and shotgun proteomics (1D-PAGE-liquid chromatography and multidimensional protein identification technology) approaches. Soybean was selected for this study due to its agronomic importance and its root size. The resulting soybean root hair proteome reference map identified 1,492 different proteins. 2D-PAGE followed by mass spectrometry identified 527 proteins from total cell contents. A complementary shotgun analysis identified 1,134 total proteins, including 443 proteins that were specific to the microsomal fraction. Only 169 proteins were identified by the 2D-PAGE and shotgun methods, which highlights the advantage of using both methods. The proteins identified are involved not only in basic cell metabolism but also in functions more specific to the single root hair cell, including water and nutrient uptake, vesicle trafficking, and hormone and secondary metabolism. The data presented provide useful insight into the metabolic activities of a single, differentiated plant cell type.

ABSTRACTAlthough nevus sebaceus is known to develop various types of secondary neoplasms, it rarely causes carcinoma and only 14 cases of secondary sebaceous carcinoma have been reported. In this study, 10 cases of sebaceous carcinoma arising in nevus sebaceus were collected. The clinicopathological features and results of immunohistochemical examinations with adipophilin, perilipin and p53 were summarized. Sebaceous carcinoma arising in nevus sebaceous predominantly occurred on the scalp (8/10) of elderly women (mean age, 67.7 years). No case was associated with Muir–Torre syndrome. We found several pathological features of sebaceous carcinoma; that is, made up mainly of germinative cells, moderate nuclear atypia without pleomorphism and many mitoses (4–28/10 high‐power field). Adipophilin and perilipin antibodies highlighted lipid drops in the cytoplasm of the malignant cells in all cases. Overexpression of p53 was seen in all cases. In two cases there were coexisting benign‐looking sebaceous lesions at the periphery of the main cancer nodule, and in these lesions p53 showed low positivity compared with the clearly malignant area. There was co‐occurrence of another neoplasm in three cases with trichoblastoma, sebaceoma and syringocystadenoma papilliferum, respectively. All cases were treated by excision of the malignant lesion, with or without inclusion of the nevus sebaceus. In a follow‐up period of 1–7 years, there was no case of recurrence, lymph node metastases or distant metastases. With these specific pathological and immunohistochemical findings using adipophilin, perilipin and p53, we have to consider the possibility that there is a tendency to underdiagnose secondary sebaceous carcinomas in nevus sebaceus. These clinicopathological features of sebaceous carcinomas developing in the nevus sebaceus seem to indicate different biological entities from de novo sebaceous carcinoma.
