Convergence in Brazil: recent trends and long-run prospects

This paper applies to the analysis of the interstate income distribution in Brazil a set of techniques that have been widely used in the current empirical literature on growth and convergence. Usual measures of dispersion in the interstate income distribution (the coefficient of variation and Theil's index) suggest that sigma-convergence was an unequivocal feature of the regional growth experience in Brazil, between 1970 and 1986. After 1986, the process of convergence seems, however, to have slowed down almost to a halt. A standard growth model is shown to fit the regional data well and to explain a substantial amount of the variation in growth rates, providing estimates of the speed of (conditional) beta-convergence of approximately 3% p.a. Different estimates of the long-run distribution implied by the recent growth trends point towards further reductions in the interstate income inequality, but also suggest that the relative per capita incomes of a significant number of states and the number of ‘very poor’ and ‘poor’ states were, in 1995, already quite close to their steady-state values.
Infection related stress adaptations in the secretome and wall proteome of Candida albicans

Alice Sorgo's main research question concerns the adaptability of the wall proteome and secretome of the opportunistic pathogenic fungus Candida albicans. The question is how do these subproteomes adapt to environmental stess (high temperatures, iron restriction, antifungal drugs) and how do these adaptations help the fungus. She found that he wall proteome and secretome of Candida albicans is highly dynamic, depending on the environment.
Rupture area and displacement of past Cascadia great earthquakes from coastal coseismic subsidence

Coastal marshes record a 6500 yr history of coseismic displacements in great earthquakes at the Cascadia subduction zone. We compiled estimates of coseismic displacement for past megathrust events based on correlations with megathrust-triggered turbidites, and estimated megathrust slip based on comparisons of marsh displacements with dislocation model predictions. Age-correlated marsh data are compatible with event rupture extents defi ned by the published turbidite record , and a 6500 yr mean recurrence interval that increases northward from ~230 to ~480 yr. Within the constraints of the marsh data, the width of the coseismic rupture zone generally agrees with the downdip width of the interseismic locked zone inferred from geodetic and thermal data. In southernmost Cascadia, where the model does not include the complex deformation near the Mendocino triple junction, the coastal data may be better fi t by a model with an ~25% narrower rupture than that inferred from regional geophysical data. At each coastal marsh site, coseismic displacements are roughly similar from event to event, independent of the time since the previous event. Slip in the A.D. 1700 earthquake was consistent with the preceding interval of strain accumulation (~200 yr) only at the northern and southern ends of the margin, but it was apparently much higher in southern Washington and northern Oregon, possibly indicating postseismic contamination and/or catch-up coseismic slip to make up for a defi cit in the preceding event. Overall agreement between the dislocation models and the marsh data for most of the margin implies that such models can be usefully applied to rupture and ground shaking predictions.

Proximities and Embedding Effects

Abstract Clusters are supposed to enhance exchanges among firms or between firms and research institutions. This is termed “proximities effects” in this paper. There are many theories explaining proximities effects, but most of them lack a clear distinction between levels of action (individuals, social networks, firms, markets, etc.). This paper is focused on this issue, claiming that it is crucial to understand the shifts between levels of action. Embeddedness of economic activity in social networks is not viewed as a static situation, but rather as a process, with a reciprocal, decoupling. Two empirical studies on innovation in the south-west of France support this argument. One bears on the relations between academic laboratories and firms, the other on the creation of innovative companies. They show that proximity and embeddedness in local social networks are just a specific context for emergence of collaborations and access to resources in the emergence phases of new companies creation, but not necessarily a specific mode of regulation of professional or technologic relations.

The Use of Ocean-Colour Data to Estimate Chl-a Trends in European Seas

Ocean-colour remote-sensing products have been used to estimate Chl-a trends in European seas with the aim to develop a new indicator based on ocean-colour data for the European Environment Agency (EEA). The new indicator, called CSI023(+), derived from satellite ocean-colour products from the MyOcean Marine Core Service (www.myocean.eu) has been defined and calculated. In our analysis, we have used 3 MyOcean satellite products: 2 global satellite products (SeaWiFS and a merged product) and one regional (adjusted to specific regional Mediterranean conditions) ocean-colour product. We have evaluated the differences among the 3 different products in estimating Chl-a trends. CSI023(+) complements the EEA CSI023 indicator for eutrophication based on chlorophyll-a (Chl-a) in-situ observations. Analysis has revealed the potential of ocean colour as a CSI023(+) indicator to detect large-scale, and in some cases, even local-scale, changes and decreasing trends of Chl-a were observed throughout the Black Sea, the Eastern Mediterranean, the southern part of the Western Mediterranean, the English Channel and the north part of the North Sea. Large areas with increasing trends were observed in the Bay of Biscay, in the North-East Atlantic regions of Ireland and the UK, in the northern part of the North Sea, in the Kattegat and in the Baltic. Specific analysis has been performed in the Mediterranean coastal areas using regional products to investigate local scale results. Validation of ocean-colour products has been carried out through comparison with observations of the Eionet EEA database. The validation results highlight that regional products produced with regional algorithms are recommended for the future.
Linking environmental flows with the distribution of black bream Acanthopagrus butcheri eggs, larvae and prey in a drought affected estuary

Estuaries are under threat from changes in freshwater flows resulting from anthropogenic impacts and climate change, with unknown consequences for estuarine biota. In the past decade, significant rain deficits in south-eastern Australia have coincided with a decrease in commercial catches of black bream Acanthopagrus butcheri, an important commercial and recreational fish species that spawn in estuaries. We investigated the temporal and spatial distribution of black bream eggs and larvae, and copepods—preferred larval prey—in relation to the hydrology of the Mitchell River, a drought-stricken tributary of Australia's largest estuarine lagoon system. We collected eggs, larvae, zooplankton and water quality data at multiple depths from 8 sampling sites over 7 fieldtrips from August to December 2008. The hydrology of the Mitchell River during this study was highly complex and influenced by freshwater flow. Spatial coupling between black bream larvae, copepods and the halocline was observed in the upper estuary. Nauplii of the copepod Gladioferens pectinatus, an important prey species for larval fish, dominated the zooplankton assemblage (>80 %) and larval gut contents. This study demonstrates that freshwater flows and the generation of salinity stratification have a large influence on the size of suitable habitat for larval bream. Drought, water abstraction and climate change could potentially reduce flows to the point where salinity stratification in the estuary is diminished, resulting in declines in replenishment to populations of black bream and possibly other estuarine-dependent fish.
The Impact of Emerging Technologies on Knowledge Management in Organizations

Man versus the machine, it is a new and growing controversy that is irking those who criticize the increased use of technology, while considered to be extremely exciting news for supporters and advocators of the growing technologies in western countries. Supporters of the rapid technological advancement have argued that it has definitely increased productivity, and improved the economy. On the other hand, the opposing side has argued that such technologies are destroying jobs more than it is generating new ones. This paper examines the impact of growing technologies as depicted by the introduction of Watson the supercomputer, which represents the epitome of technological advancement, on knowledge management in organizations, by focusing on three important components that shape any business; people as identified by managers and employees, organizational processes, and the emerging technologies. The paper proposes a framework for managing knowledge and knowledge workers as well as proposing an adapted prototype design of how the future digitized organizational structure should be, and offers recommendations in this regard.
Semantic Spatial Representation, an Experimental Proposal in the Framework of eParticipation

The article explores the theme of collaborative construction of territorial knowledge through the use of ICTS, proposing a new approach to spatial representation based on semantic ontologies. The theoretical perspective is applied in a recent experimentation conducted in collaboration between the Politecnico and the Universiti di Torino, called OnToMap-Community Maps 3.0. The essay is divided into two parts. The first part aims to define the theoretical framework of the eParticipation practices, specifying which approach to participation is assumed as conceptual background. The second part focuses on the web-based application OnToMap, which relies on an territorial ontology for encourage construction of collective and shared knowledge of the places. It is therefore proposed a definition of "Social Semantic Mapping" based on the integration of GIS tools, VGI practices and Web 3.0 applications. The article ends with a reflection on semantic and cartographic representation of urban space and its potential in terms of citizen empowerment.
Promoting Loud Thinking about Light in Elementary School Science.

In studying young children learning in inclusive environments, we designed ways to enable children to explore scientific knowledge that is usually believed to require later didactic teaching. Aspects of this design under scrutiny here are, first, the capacity of natural learning to lead to effective scientific ideas, and second, further clarification of the rcle of context. We found that in conversational modes, children were able to generate ideas and theories, to test them (by extended discussion in which they examined the logical consequences of holding those ideas, and by subjecting them to critical tests), and then to generate further theories. In doing so, the role of analogical analysis was especially productive; the simile of moving objects bouncing from a surface helped the idea of light traveling to emerge naturally (a contrary finding to the belief that understanding the propagation of light should precede the study of reflection). In this environment children studied keenly and cooperatively, kept records and critiqued the topic. As a result of this learning our view on the ages at which children might begin to deal with scientific ideas have been revised
Thru-reflect-line calibration for substrate integrated waveguide devices with tapered microstrip transitions

One of the main problems when exciting or measuring substrate integrated waveguide (SIW) devices lies in the need of a good interconnection with planar structures. In this reported work, the negative effects produced by the connectors and the tapered microstrip-to-SIW transitions are de-embedded from the measurements of the SIW structure by a thru-reflect-line calibration with an adequate and cheap SIW calibration kit.
Insulin Ã¢ÂÂlike Growth Factor 1 in Adolescent Girls with Anorexia Nervosa:Relation to Bone Formation Parameters

Objective: Puberty is associated with marked changes in body weight and hormonal profile related to pubertal stage such as insulin-like growth factor 1 (IGF-1). These changes are also associated with Anorexia Nervosa (AN) and may impact bone. Thus our study aimed to study bone metabolism and possible etiology of osteopenia in Egyptian adolescent AN girls. Method: Twenty five adolescent girls were studied compared to 30 healthy age - and pubertal stage- matched controls. All participants were subjected to clinical evaluation, neuropsychiatric assessment, auxological measurements, bone age assessment, bone density and body composition assessment; and measurement of serum growth hormone (GH), IGF-1, ionized calcium, phosphorus, 25 hydroxy vitamin D [25-(OH)D] and serum osteocalcin (OC). Results: Lean body mass and Bone Mineral Density (BMD) were significantly reduced in AN patients compared with controls even when controlled for height. Serum GH was elevated significantly in patients (P=0.02). Serum IGF-1 level was reduced significantly in AN (P=0.0001). Serum ionized calcium, vitamin D and OC levels were significantly lower in patients (P=0.03, 0.04 and 0.02 respectively). IGF-1 was strongly positively correlated with OC in patients (r=0.865; P=0.001). In stepwise regression analysis, IGF-1 caused 73% (r2=0.75; P=0.001) of variation in OC levels in AN. Discussion: This study describes low bone formation in AN compared with age - and pubertal stage-matched adolescents. Serum levels of IGF-1 are highly correlated with bone formation and thus, IGF-1 measurement can be used as a marker for bone osteoblastic activity in AN.

On the nonrealizability of braid groups by homeomorphisms

In this paper, we will show that the projection $\text{Homeo}^+(D^2_n)\to B_n$ does not have a section; i.e. the braid group $B_n$ cannot be geometrically realized as a group of homeomorphisms of a disk fixing the boundary point-wise and $n$ marked points in the interior as a set. We also give a new proof of a result of Markovic that the mapping class group of a closed surface cannot be geometrically realized as a group of homeomorphisms.
Successful Regeneration and Characterization of Anther Derived Rice Hybrid Plants from O. Sativa L. X O. Rufipogon Griff.

Doubled haploid regenerated through anther culture of wide cross rice hybrids is one of the potential tools to produce various useful genetic and cytogenetic stocks for molecular studies. In this study, an interspecific hybrid derived from Oryza sativa and O. rufipogon was subjected to anther culture with the aim to regenerate doubled haploid population for their characterization. A total of 21 green and 31 albino plants were obtained from 1904 anthers of O. sativa cv. Himali x O. rufipogon . Six types of androclonal variants were identified based on morphology and panicle characteristics of regenerated plants. Among 21 plants, only six were found diploid with partially fertility. Despite the sterility and preponderance of wild traits, some of the plants showed useful traits such as increased in panicle and spikelet length, reduced shattering and awning, and large size anther as in O. rufipogon . Two of the regenerants were superior for panicle related traits over either parent. The genotyping study using SSR markers also revealed the substantial variation among regenerants. At least three allelic variants were recorded among individual plants based on our preliminary study. The regenerated doubled haploid plants showed large amount of useful variation both at phenotype and molecular level and they can be exploited to enrich the current rice gene pool.

Contribution of Social Disclosure and Organizational Culture to Create Financial Value of Tunisian Companies

The main objective of this paper is to explain the contribution of the social disclosure and the characteristics of organizational culture on the level of financial value creation of Tunisian companies. Theoretically, we supported a literature review rich in theoretical and empirical studies of relationship between these concepts. This theoretical framework allowed us to develop our research hypotheses. As for methodology, we worked on a sample of 23 Tunisian companies listed in Tunis Stock Exchange on a five-year period extending from 2007 to 2011.Finally for the results, we found, first, that the social disclosure has a remarkable effect on creating financial value. On the other hand, we find that organizational culture has a significant influence on creating financial value of companies through some items, namely: collaboration skills and organizational learning.
The Determinant Factors that Influence Customers’ Behavioral Intention in Property

The property industry acts as vital sector whereby the service environment directly correlates the customers’ behavioral intention in purchasing a property. However, to date, a study regarding service environment and its impact still not fully addressed in the property industry. Thus, the purpose of this study is to investigate the relationship between service environment and customers’ behavioral intention moderated by income in Malaysian property industry. A total of 357 respondents were participated in this study by using a convenience sampling. The result shown that lower middle income was significantly moderated the relationship between service environment and customers’ behavioral intention.Keywords: Service Environment; Customer’s Behavioral Intention; Property Industry; MalaysiaeISSN 2398-4295 © 2018.

COOPERATIVE FACE HALLUCINATION USING MULTIPLE

This paper proposes a cooperative example-based face hallucination method using multiple references. The proposed method first uses clustering and residual prototype faces construction to improve the performance of hallucinating a single low-resolution (LR) face to obtain a high-resolution (HR) counterpart. In the case that multiple LR face images for a person are available, a unique feature of the proposed method is to cooperatively enhance the qualities of hallucinated HR images by taking into account the multiple input face images jointly as prior models. Experimental results demonstrate that the proposed cooperative method achieve significant subjective and objective improvement over single-prior schemes.
Examining shifts in zooplankton community variability following biological invasion

We examined 20 yr of zooplankton samples from Harp Lake for shifts in zooplankton variability following invasion by zooplankton predator Bythotrephes longimanus, using organism body size—as measured at high resolution by Laser Optical Plankton Counter (LOPC)—as the primary metric of investigation. A period of transitory high variability in the 2 yr post‐invasion was observed for both body size compositional variability and aggregate variability metrics, with both measures of variability shifting from low or intermediate to high variability immediately following invasion, before shifting again to intermediate variability ∼ 2 yr post‐invasion. Aggregate and compositional variability dynamics were also considered in combination over the study period, revealing that the period of transitory high variability coincided with a shift from a community‐wide stasis variability pattern to one of asynchrony, before a shift back to stasis 2 yr post‐invasion. These dynamics were related to changes in the significant zooplankton species within the Harp Lake community over the pre‐ and post‐invasion periods, and are likely to be indicative of changes in the stability in the zooplankton community following invasion by Bythotrephes. The dual consideration of aggregate and compositional variability as measured by LOPC was found to provide a valuable means to assess the ecological effects of biological invasion on zooplankton communities as a whole, extending our knowledge of the effects of invasion beyond that already revealed through more traditional taxonomic investigation.
The Determinants of Household Demand for Mobile Broadband in Indonesia

Based on the Global Information Technology 2013 report, mobile broadband user in Indonesia is increasing at 70% per year as well as internet users will grow from 55 million in 2012 to 125 million in 2015, which is expected to accelerate as Unfortunately, there are still drawbacks in understanding of potential benefits from widespread access to mobile broadband due to the lack of government efforts as well as studies in capturing demand of mobile broadband nationwide. The study concludes that income plays a less important role in its effect on mobile broadband access than geographical area, indicating that affordability is not an issue to further develop broadband. The importance of geographical characteristics confirms the studies by Rappoport (2002) and Steinberg, Degagne and Dough (2008). The fact that urban areas, and Java and its cities, are more developed in terms of broadband development leads to a need to develop infrastructure more evenly throughout the country.
