On achieving sustainable development: The Costa Rican model
Authors: Figueres José María 
Published: December 2007

AbstractOne of the hottest buzzwords in today's global corporate environment is “sustainability.” But long before the topic became “cool,” it was on the mind and on the agenda of Costa Rica's president, José María Figueres. In this well‐thought‐out article, Figueres maps the route that he forged for Costa Rica's future as a developing country leveraging its resources into a model of sustainable development for Latin American emerging economies. Using concrete examples, he explains the thought leadership behind projects that have moved Costa Rica into the forefront of countries doing well by also doing good. © 2008 Wiley Periodicals, Inc.
Mexican American Adolescents’ Cultural Orientation, Externalizing Behavior and Academic Engagement: The Role of Traditional Cultural Values

Published: December 2007

AbstractThis study of 598 7th grade students of Mexican origin examined the role of traditional cultural values as a mediator of the effects of immigrant status, Mexican cultural orientation and Anglo cultural orientation on adolescent externalizing behavior and academic engagement. Immigrant status of adolescents and their maternal caregivers uniquely predicted increased Mexican cultural orientation and decreased Anglo cultural orientation, and both Mexican and Anglo cultural orientation related positively to adolescents’ endorsement of traditional cultural values. Endorsement of traditional cultural values related, in turn, to decreased externalizing behaviors and increased academic engagement and these findings were replicated across adolescent and teacher report of these two outcomes. Tests of mediation provided further evidence to support these pathways. Findings support the central importance of traditional cultural values as a protective resource that explains why immigrant youth exhibit fewer externalizing problems and increased academic engagement when compared to their second and third generation peers.
Effect of blueberry feeding on plasma lipids in pigs

Published: December 2007

Two feeding trials were conducted with pigs to determine the effects of blueberry supplementation on plasma lipid levels and other indices of cardiovascular benefit. In the first trial, where basal diets contained a high level of plant-based components (70 % soya, oats and barley), supplementation with 1, 2 and 4 % blueberries resulted in a decrease in total, LDL- and HDL-cholesterol. The greatest reduction was observed in the 2 % blueberry-fed pigs, where total, LDL- and HDL-cholesterol were reduced 11·7, 15·1 and 8·3 %, respectively. In the second trial where basal diets contained only 20 % (w/w) of soya, oats and barley, the lipid-modulating effect of blueberries was attenuated, so that supplementation with 1·5 % blueberries reduced total cholesterol by 8 %, which occurred only in pigs whose diets had been supplemented with cholesterol (0·08 %), NaCl (0·11 %) and fructose (9 %). In the first feeding trial, blueberry supplementation had no effect on blood platelet activity. Blueberry supplementation also had no effect on the susceptibility of leucocyte DNA to oxidation in the first trial and no effect on the susceptibility of LDL to oxidation in the second trial. Results of these two feeding trials are discussed in relation to the effects of basal diet composition on lipid-modulating effects of blueberries.
Those dreaded memes: The advantage of memetics over “symbolic inheritance”
Authors: Blackmore Susan 
Published: December 2007

AbstractJablonka & Lamb (J&L) reject “the dreaded memes,” but memetics can explain human uniqueness and culture (as a product of the ability to imitate) without depending on their slippery notion of symbolism. Modern memes show the beginnings of a division into replicators and vehicles, and the replacement of reconstructive processes with systems of blind copying, variation, and selection.
Bridging the gap: The developmental aspects of evolution
Authors: Jablonka Eva , Lamb Marion J. 
Published: December 2007

AbstractThe commentaries onEvolution in Four Dimensionsreflect views ranging from total adherence to gene-centered neo-Darwinism, to the acceptance of non-genetic and Lamarckian processes in evolution. We maintain that genetic, epigenetic, behavioral, and cultural variations have all been significant, and that the developmental aspects of heredity and evolution are an important bridge that can unite seemingly conflicting research programs and different disciplines.
Behavioral innovation and phylogeography
Authors: Deleporte Pierre 
Published: December 2007

AbstractIndirect identification of innovations in wild populations involves inferring past, unobserved behavioral events. Such historical inference can make simple use of present distribution patterns of differently behaving individuals, but population genetic studies are a potential source of complementary relevant information. Methodological lessons can be taken from phylogeography, that is, molecular approaches to the history of population spatial distribution patterns and gene flows. Opportunities for such studies in primates should increase with the developing population genetic studies used for management and conservation purposes.
Knowing psychological disposition might help to find innovation
Authors: Gajdon Gyula K. 
Published: December 2007

AbstractRamsey et al.'s article provides a more sensitive framework for comparative innovation than others' operationalisations have done. Nevertheless, a methodology has to be elaborated in order to determine to what degree a behaviour is novel. Psychological processes have to be considered when evaluating the value of reference groups and in order to figure out where to look for innovation.
Can a restrictive definition lead to biases and tautologies?
Authors: Giraldeau Luc-Alain , Lefebvre Louis , Morand-Ferron Julie 
Published: December 2007

AbstractWe argue that the operational definition proposed by Ramsey et al. does not represent a significant improvement for students of innovation, because it is so restrictive that it might actually prevent the testing of hypotheses on the relationships between innovation, ecology, evolution, culture, and intelligence. To avoid tautological thinking, we need to use an operational definition that is taxonomically unbiased and neutral with respect to the hypotheses to be tested.
Genetic assimilation of behaviour does not eliminate learning and innovation
Authors: Hunt Gavin R. , Gray Russell D. 
Published: December 2007

AbstractRamsey et al. attempt to clarify methodological issues for identifying innovative behaviour. Their effort is seriously weakened by an underlying presumption that the behavior of primates is generally learned and that of non-primates is generally “innate.” This presumption is based on a poor grasp of the non-primate literature and a flawed understanding of how learned behaviour is genetically assimilated.
Social learning is central to innovation, in primates and beyond
Authors: Logan Corina J. , Pepper John W. 
Published: December 2007

AbstractMuch of the importance of innovation stems from its capacity to spread via social learning, affecting multiple individuals, thus generating evolutionary and ecological consequences. We advocate a broader taxonomic focus in the field of behavioral innovation, as well as the use of comparative field research, and discuss the unique conservation implications of animal innovations and traditions.
Innovation and the grain problem
Authors: Russon Anne , Andrews Kristin , Huss Brian 
Published: December 2007

AbstractOur concern is with Ramsey et al.'s method for identifying innovation. We show that either it yields false positives or the authors offer insufficient guidance for its application. To avoid these results, the authors need to modify the key or offer better guidelines for delineating input. Either choice requires addressing the processes that generate a behavior.
Defining and detecting innovation: Are cognitive and developmental mechanisms important?
Authors: Sargeant Brooke L. , Mann Janet 
Published: December 2007

AbstractAlthough the authors' ingenuity in identifying criteria for innovation for field studies is appealing, most field studies will lack adequate data. Additionally, their definition does not clearly distinguish innovation from individual learning and is vague about cognitive mechanisms involved. We suggest that developmental data are essential to identifying the causes and consequences of learning new behaviors.
Lasing properties and nonlinearities of dyes under high power pumping

Published: December 2007

AbstractNitrogen lasers have been used for many years to make dye solutions lase. A nitrogen laser, which transverse electrical discharge in gas at atmospheric pressure has been built in our laboratory. It has been characterized and applied to pump different dyes: Rhodamine 6G, Coumarin 440, DOTCI, and pyranine in simple “on axis” geometric configuration. It has been shown that pyranine can lase in the absence of any optical external mirror cavity, this happens at very low threshold, and in different solvents. Dyes under consideration can be grouped into two major classes according to their lasing behavior independently on their concentration in the solvent: Rhodamine 6G and DOTCI can lase both axially or transversally and Coumarin 440 and pyranine can lase only axially. Other intriguing features have been observed that span from simultaneous multiple beam generation, to super fluorescence and to distribute axial pumping of dye solutions. A preliminary basis for understanding and controlling such processes is the spatial energy distribution and the energy density of the beam.
Clans for Markets: The Social Organization of Inter-Firm Trading Relations in China's Automobile Industry
Authors: Lee Khan-Pyo 
Published: December 2007

AbstractThis article addresses one of the institutional elements identified as essential to modern capitalism, but which has received little research attention, that is, the “freedom of the markets.” Through an analysis of inter-firm trading ties for the procurement of intermediate products in China's automobile industry, this article demonstrates that to a significant extent the exchange structure remains bound by particularistic networks of trading between institutionally tied actors. It also shows how the resultant “dualism” in market networks, which discriminates between actors sharing particularistic ties and those that do not, is derailing the rational development of the industry by sustaining a “cellular” pattern of industrial development. The case of the auto industry suggests that it may specifically be the large-scale, modern industrial sectors – which require resources to be mobilized and actors to be co-ordinated at vast scale and scope – where the need for the “rational capitalistic establishments” are greatest, and therefore the failure to institute them may constitute a real hurdle to development.
The Political Ecology of Pollution Enforcement in China: A Case from Sichuan's Rural Industrial Sector
Authors: Tilt Bryan 
Published: December 2007

AbstractThis article uses a case study approach to examine the processes and consequences of pollution enforcement in an industrial township in rural Sichuan. China's national pollution emissions standards are relatively strict, but enforcement is the responsibility of some 2,500 Environmental Protection Bureaus (EPBs) within municipal and county governments. EPB officials exercise considerable discretion in prioritizing and carrying out enforcement activities, but exactly what factors influence regulatory behaviour within EPBs is poorly understood. Data for the article are drawn from interviews with EBP officials, township government officials, industrial managers and local residents, as well as a review of township and district financial records and pollution enforcement records. In this case study, EPB enforcement priorities and actions were guided by State Council directives and State Environmental Protection Administration policy, but citizen complaints and media exposure regarding polluting factories also played a key role, and action culminated in the forced closure of township factories. The article uses political ecology as an analytical framework for understanding how pollution enforcement is shaped by the competing values, goals and priorities within the EPB and the administrative unit in which it operates. This is crucial in China, where the decentralized nature of environmental oversight requires an examination of both policy formulation and implementation. The implications of pollution enforcement on rural enterprises for ecological health, fiscal revenue and rural development are also discussed.
Prevalence of RTI/STI agents and HIV infection in symptomatic and asymptomatic women attending peripheral health set-ups in Delhi, India
Authors: RAY K. , BALA M. , BHATTACHARYA M. , MURALIDHAR S. , KUMARI M. , SALHAN S. 
Published: December 2007

SUMMARYThe study was carried out in symptomatic and asymptomatic women attending peripheral health centres to determine the laboratory prevalence of sexually transmitted infection (STI), reproductive tract infection (RTI) and HIV. A total of 4090 women in four study groups were subjected to general and speculum examination and screened for aetiological agents of RTI/STI by standard laboratory techniques. The main complaint was vaginal discharge, singly (11·2%) or along with other symptoms (49·0%). Prevalence of RTI/STI/HIV infection was 36·8%. Agents of RTIs were harboured by 24·3% and that of STIs by 12·5%. HIV seroprevalence was very low (0·1%). HSV-2 represented the commonest aetiological agent of STIs, suggesting the necessity of including anti-HSV treatment in the national syndromic management guidelines. The present study highlights the importance of routine RTI/STI screening of antenatal mothers to avoid adverse consequences to the unborn child, and periodic surveys to detect the infection pattern in symptomatic and asymptomatic women, in order to control HIV infection.
A Sturzstrom-like cliff fall on the Chalk coast of Sussex, UK

Published: December 2007

Abstract

In 1914 a notable cliff fall occurred on the chalk coast of the Seven Sisters in Sussex. Debris from the fall travelled outwards across the shore platform in front of the cliff for a distance of about 75 m, forming a narrow tongue-like projection. The reason why the debris exhibited such mobility is uncertain, but it may have flowed in a similar fashion to a sturzstrom, despite its modest volume (c. 12500m

) and the equally modest height of the cliff (44–45 m). If this suggestion is correct, the minimum volume of detached rock required to trigger sturzstrom-type flow is 1–2 orders of magnitude less than is commonly claimed.
The propagation of wave impact induced pressures into cracks and fissures
Authors: Wolters G. , Müller G. 
Published: December 2007

Abstract

Rock cliffs and blockwork coastal structures often suffer a peculiar type of damage, whereby individual blocks are removed out of their location towards the sea. The location of damage suggests that breaking wave action is the main cause. It has been suggested that wave impact pressures travel into the water or air filled cracks and fissures of the structures, leading to large pressures acting inside of the structure or cliff and to the removal of blocks. This assumption was only recently confirmed for water filled cracks with a series of model tests at Queen's University Belfast. Real cracks in rock cliffs are, however, often only partially filled with water. A new experimental study, also conducted at Queen's University Belfast, revealed that wave impact generated pressures can ravel into both fully or partially water filled cracks or joints. In partially submerged cracks the pressure pulse was found to travel in the air, propagating fast and with little attenuation deep into the structure, signifying that partially filled cracks are potentially more dangerous for the integrity of the structure than completely water filled cracks. These pressure pulses may be the main cause for the

removal of blockwork in coastal engineering structures or of rock cliff material.
Coastal cliff erosion vulnerability on the Canadian east coast (Baie des Chaleurs area): a multi-parameter visualization tool
Authors: Daigneault M. , Bouchardon J-L. , Guy B. 
Published: December 2007

Abstract
In order to assess a cliff&rss vulnerability to erosion, researchers must consider a number of parameters that collectively account for all possible erosional processes. The authors have developed a radial diagram that allows the most active processes of erosion to be visualized (e.g. hydrodynamic, gravity-driven or atmospheric), and when such diagrams are presented on a map, they can be used to rapidly identify the contributing erosional processes at a given location. The diagram, developed for the Baie des Chaleurs region (eastern coast of Canada), displays numerical values that represent the relative importance of various weakening parameters for a set of cliffs. In addition, a colour code represents the dominant lithology, and the diagram diameter is a function of the erosion rate. The data for each diagram are based on field observations, experimental work and results of mineralogical and petrophysical analyses. Ten fundamental parameters were used to assess the structural, petrophysical and environmental processes of erosion: porosity, percentage of matrix or cement, homogeneity of the stratification, presence of schistosity, fracture density, number of fracture sets, presence of faults, dip of the strata, effect of waves, and the presence of groundwater. Coastal managers can use these diagrams in conjunction with natural risk maps to estimate the vulnerability of a cliff and decide whether engineering structures are required for preservation.
Observations from the Alpine Tethys and Iberia–Newfoundland margins pertinent to the interpretation of continental breakup
Authors: Manatschal G. , Müntener O. , Lavier L. L. , Minshull T. A. , Péron-Pinvidic G. 
Published: December 2007

Abstract
Although the Iberia–Newfoundland and Alpine Tethys margins are of different age and ultimately had a different fate, they share remarkable similarities. Both pairs of margins show a change from initially distributed and decoupled extension to later localized, coupled and asymmetric extension that results in thinning of the crust and exhumation of subcontinental mantle. The change in the mode of extension together with the localization of deformation reflects an evolution of the bulk rheology of the extending lithosphere. In this paper we summarize the pertinent geological observations for the Iberia–Newfoundland and Alpine Tethys margins. We describe the stratigraphic evolution, the fault geometry, basin architecture, and magmatic and metamophic evolution of the two pairs of margins from initial rifting to final continental breakup. This description forms a basis for understanding the evolution of the bulk rheology and how the various processes interact during progressive lithospheric extension. For the Iberia–Newfoundland and Alpine Tethys margins initial rifting appears to be controlled by inherited heterogeneities and mechanical localization processes, whereas final rifting and lithospheric rupture is controlled by serpentinization, magmatic and thermal weakening. At other margins, these modes may interact in a different way depending on the prerift conditions and the evolution of the rheology during rifting.
Continental lithospheric thinning and breakup in response to upwelling divergent mantle flow: application to the Woodlark, Newfoundland and Iberia margins
Authors: Kusznir N. J. , Karner G. D. 
Published: December 2007

Abstract
Depth-uniform stretching is not the dominant deformation process for thinning continental lithosphere leading to breakup; it cannot explain the observed depth-dependent lithosphere stretching and mantle exhumation at rifted continental margins. Depth-dependent lithosphere thinning, in which stretching of the lower crust and lithosphere mantle greatly exceeds that of the upper crust, has been observed at many non-volcanic and volcanic rifted continental margins including conjugate margin pairs. Passive continental margins show a paucity of brittle deformation in the upper crust during continental lithosphere thinning leading to breakup and sea-floor spreading initiation. A new model of rifted continental margin formation has been developed that assumes that deformation and thinning of continental lithosphere leading to breakup occurs in response to an upwelling divergent flow field within continental lithosphere and asthenosphere, and that this deformation evolves into sea-floor spreading. The new model successfully predicts depth-dependent stretching of continental margin lithosphere for both non-volcanic and volcanic margins and mantle exhumation at non-volcanic margins, both of which are observed, but are not explained, by existing depth-uniform continental lithosphere stretching models. The new model provides a balance of extensional strain, supplies an explanation for the paucity of synrift brittle deformation, and offers a simple transition from prebreakup lithosphere thinning to sea-floor spreading. The observed diversity of rifted continental margin structure and width of the ocean–continent transition can be explained by variability in the form of the upwelling divergent flow field. The new upwelling divergent flow model of continental lithosphere thinning leading to continental breakup successfully predicts the observed bathymetry and margin geometry for the most recent segment of sea-floor spreading initiation in the Woodlark Basin in the western Pacific, and the observed bathymetry and free air gravity anomaly for the Newfoundland and Iberian margins.
