Tobin meets Oates: Solidarity and the optimal fiscal federal structure

We explore the implications for the optimal degree of fiscal decentralization when people spreferences for goods and services, which classic treatments of fiscal federalism (Oates, 1972)place in the purview of local governments, exhibit specific egalitarianism (Tobin, 1970), orsolidarity. We find that a system in which the central government provides a common minimumlevel of the publicly provided good, and local governments are allowed to use their ownresources to provide an even higher local level, performs better from an efficiency perspectiverelative to all other systems analyzed for a relevant range of preferences over solidarity.

Information security and the enforcement of secrecy : the practical application of quantum key distribution

There is no doubt about the necessity of protecting digital communication: Citizens are entrusting their most confidential and sensitive data to digital processing and communication, and so do governments, corporations, and armed forces. Digital communication networks are also an integral component of many critical infrastructures we are seriously depending on in our daily lives. Transportation services, financial services, energy grids, food production and distribution networks are only a few examples of such infrastructures. Protecting digital communication means protecting confidentiality and integrity by encrypting and authenticating its contents. But most digital communication is not secure today. Nevertheless, some of the most ardent problems could be solved with a more stringent use of current cryptographic technologies. Quite surprisingly, a new cryptographic primitive emerges from the ap-plication of quantum mechanics to information and communication theory: Quantum Key Distribution. QKD is difficult to understand, it is complex, technically challenging, and costly-yet it enables two parties to share a secret key for use in any subsequent cryptographic task, with an unprecedented long-term security. It is disputed, whether technically and economically fea-sible applications can be found. Our vision is, that despite technical difficulty and inherent limitations, Quantum Key Distribution has a great potential and fits well with other cryptographic primitives, enabling the development of highly secure new applications and services. In this thesis we take a structured approach to analyze the practical applicability of QKD and display several use cases of different complexity, for which it can be a technology of choice, either because of its unique forward security features, or because of its practicability.

Estudi de software lliure en diferents entorns

El software lliure està tenint últimament un pes cada cop més important en les empreses, però encara és el gran desconegut per a molta gent. Des de la seva creació als anys 80 fins ara, hi ha hagut un creixement exponencial de software lliure de gran qualitat, oferint eines per a tot tipus de necessitats, eines ofimàtiques, gestors de correu, sistemes de fitxer, sistemes operatius…. Tot aquest moviment no ha passat desapercebut per a molts usuaris i empreses, que s’han aprofitat d’ell per cobrir les seves necessitats. Pel que fa a les empreses, cada cop n’hi ha més que en petita o gran mesura, utilitzen el software lliure, ja sigui per el seu menor cost d’adquisició, o bé per la seva gran fiabilitat o per que és fàcilment adaptable o per no establir cap lligam tecnològic, en definitiva per tenir més llibertat. En el moment de la creació d’una nova empresa, on es parteix de zero en tota la tecnologia informàtica, és el moment menys costòs d’implementar l’arquitectura informàtica amb software lliure, és quan l’impacte que té sobre l’empresa, usuaris i clients és menor. En les empreses que ja tenen un sistema informàtic, caldrà establir un pla de migració, ja sigui total o parcial. La finalitat d’aquest projecte no és la de dir quin software és millor que l’altre o de dir quin s’ha d’instal•lar, sinó el de donar a conèixer el món del software lliure, mostrar part d’aquest software, fer alguna comparativa de software lliure amb software propietari, donant idees i un conjunt de solucions per a empreses, per què una empresa pugui agafar idees d’implementació d’algunes de les solucions informàtiques exposades o seguir algun dels consells proposats. Actualment ja hi ha moltes empreses que utilitzen software lliure. Algunes només n’utilitzen una petita part en les seves instal•lacions, ja que el fet de que una empresa funcioni al 100% amb software lliure, tot i que n’hi comença ha haver, de moment ho considero una mica arriscat, però que en poc temps, aquest fet serà cada cop més habitual.

Business Sphere, Vol. 18, no.1

Information technology is a strong and important sector of the Iowa economy employing 30,000 Iowans at more than 2,000 companies, according to a new analysis from Battelle Institute consultants. The strength of Iowa’s IT industry is based in the service-segment. Internet and data services, communications network services, and software and computer services constitute 81 percent of all IT employment. Slightly ahead of U.S. trends, these service sectors compose the backbone of Iowa’s IT industry,

Electronic journals, scholarly communication and libraries

The recent surge in scientific electronic journals began when libraries began having access to the WWW in the mid-1990s. The shift from paper to digital has affected the traditional alignment and role of the primary "stakeholders" -mainly authors, publishers, universities and libraries. The author offers a brief review of the history of the scholarly journal followed by the evolution of e-journals in during the past two decades. The article then focuses on the implications that these have had on traditional library processes and services such as selection, acquisitions, cataloguing, storage, preservation and user services. In the conclusion the author speculates on the long term effect of Web-based publishing on the format of the traditional scholarly journal as it has existed for over 300 years.

Iowa Library Services Reorganization Report, 2010.

Legislation passed during the 2010 legislative session required a study of ways to streamline state-funded library operations and services. The Iowa Library Association was asked to lead this endeavor and named a committee to carry out the study. The study resulted in the development of a plan for reorganization, which is outlined in the Iowa Library Services Reorganization Report. The Iowa Library Reorganization Committee was representative of the Library Services Areas, the State Library of Iowa, and public libraries of all sizes from all around the state. The president of the Iowa Library Association and the State Librarian also served as members of the Committee. The report was submitted to members of the Iowa legislature on November 1, 2010.

Wind Energy Where Wind and Innovation Work, 2010

Centrally located in America’s upper Midwest, Iowa lies in the heart of a 12-state region that will have installed an average of 2,701 mfi per year through 2014. In 2009 alone, this region, which is within one day delivery from Iowa, installed turbines valued at $7.8 billion! Once you understand how this exploding growth in the market intersects with the supply chain established by over 250 Iowa companies that are already providing components and services to wind energy manufacturers, you have an outstanding picture of exactly why all major wind manufacturing components are made in Iowa.

The First privatization : selling SOEs and privatizing public monopolies in fascist Italy, 1922-1925

[cat] El primer govern feixista d’Itàlia va aplicar una política de privatització a gran escala entre 1922 i 1925. El govern va privatitzar el monopoli estatal de llumins, el monopoli estatal d’assegurances de vida, va vendre la major part de la xarxa i serveis de telefònica pública a empreses privades, va reprivatitzar el major productor de productes metàl·lics, i va atorgar concessions a empreses privades per construir i explotar autopistes de peatge. Tot i que algunes consideracions ideològiques van poder tenir alguna influència, la privatització va ser usada sobre tot com un instrument polític per construir confiança amb els grans industrials i per augmentar el suport al govern i al Partito Nazionale Fascista. La privatització també va contribuir a equilibrar el pressupost públic, qüestió aquesta que va ser el principal objectiu de la primera fase de la política econòmica feixista.

Surface mapping, organic matter and water stocks in peatlands of the Serra do Espinhaço meridional - Brazil

Peatlands are soil environments that store carbon and large amounts of water, due to their composition (90 % water), low hydraulic conductivity and a sponge-like behavior. It is estimated that peat bogs cover approximately 4.2 % of the Earth's surface and stock 28.4 % of the soil carbon of the planet. Approximately 612 000 ha of peatlands have been mapped in Brazil, but the peat bogs in the Serra do Espinhaço Meridional (SdEM) were not included. The objective of this study was to map the peat bogs of the northern part of the SdEM and estimate the organic matter pools and water volume they stock. The peat bogs were pre-identified and mapped by GIS and remote sensing techniques, using ArcGIS 9.3, ENVI 4.5 and GPS Track Maker Pro software and the maps validated in the field. Six peat bogs were mapped in detail (1:20,000 and 1:5,000) by transects spaced 100 m and each transect were determined every 20 m, the UTM (Universal Transverse Mercator) coordinates, depth and samples collected for characterization and determination of organic matter, according to the Brazilian System of Soil Classification. In the northern part of SdEM, 14,287.55 ha of peatlands were mapped, distributed over 1,180,109 ha, representing 1.2 % of the total area. These peatlands have an average volume of 170,021,845.00 m³ and stock 6,120,167 t (428.36 t ha-1) of organic matter and 142,138,262 m³ (9,948 m³ ha-1) of water. In the peat bogs of the Serra do Espinhaço Meridional, advanced stages of decomposing (sapric) organic matter predominate, followed by the intermediate stage (hemic). The vertical growth rate of the peatlands ranged between 0.04 and 0.43 mm year-1, while the carbon accumulation rate varied between 6.59 and 37.66 g m-2 year-1. The peat bogs of the SdEM contain the headwaters of important water bodies in the basins of the Jequitinhonha and San Francisco Rivers and store large amounts of organic carbon and water, which is the reason why the protection and preservation of these soil environments is such an urgent and increasing need.

Title IV-B Child and Family Service Plan 2010 Annual Progress and Service Report, June 2010

In June 2009, the Iowa Department of Human Service (IDHS) developed a Child and Family Service Plan (CFSP) that sets forth the Department’s vision and goals to be accomplished for FYs 2010 through 2014. The purpose of the CFSP is to strengthen the States’ overall child welfare system and to facilitate the state’s integration of the programs that serve children and families into a comprehensive and continuum array of child welfare services from prevention and protection through permanency. These programs include title IV-B, subparts 1 and 2 of the Act, the Child Abuse Prevention and Treatment Act (CAPTA), the Chafee Foster Care Independence Program (CFCIP), and the Education and Training Vouchers (ETV) programs for older and/or former foster care youth. IDHS administers the IV-B, CAPTA, CFCIP and the ETV programs described within Iowa’s CFSP. Iowa’s Annual Progress and Services Report (APSR) provides an annual update on the progress made toward accomplishing the goals and objectives identified in the state’s CFSP for the previous fiscal year (2009-2010) and the planned activities for next fiscal year (2010-2011) .

SPATIAL DEPENDENCE OF ELECTRICAL CONDUCTIVITY AND CHEMICAL PROPERTIES OF THE SOIL BY ELECTROMAGNETIC INDUCTION

Brazilian soils have natural high chemical variability; thus, apparent electrical conductivity (ECa) can assist interpretation of crop yield variations. We aimed to select soil chemical properties with the best linear and spatial correlations to explain ECa variation in the soil using a Profiler sensor (EMP-400). The study was carried out in Sidrolândia, MS, Brazil. We analyzed the following variables: electrical conductivity - EC (2, 7, and 15 kHz), organic matter, available K, base saturation, and cation exchange capacity (CEC). Soil ECa was measured with the aid of an all-terrain vehicle, which crossed the entire area in strips spaced at 0.45 m. Soil samples were collected at the 0-20 cm depth with a total of 36 samples within about 70 ha. Classical descriptive analysis was applied to each property via SAS software, and GS+ for spatial dependence analysis. The equipment was able to simultaneously detect ECa at the different frequencies. It was also possible to establish site-specific management zones through analysis of correlation with chemical properties. We observed that CEC was the property that had the best correlation with ECa at 15 kHz.

Video analysis software increases the interrater reliability of video gait assessments in children with cerebral palsy.

The aim of this study was to determine the effect of using video analysis software on the interrater reliability of visual assessments of gait videos in children with cerebral palsy. Two clinicians viewed the same random selection of 20 sagittal and frontal video recordings of 12 children with cerebral palsy routinely acquired during outpatient rehabilitation clinics. Both observers rated these videos in a random sequence for each lower limb using the Observational Gait Scale, once with standard video software and another with video analysis software (Dartfish(®)) which can perform angle and timing measurements. The video analysis software improved interrater agreement, measured by weighted Cohen's kappas, for the total score (κ 0.778→0.809) and all of the items that required angle and/or timing measurements (knee position mid-stance κ 0.344→0.591; hindfoot position mid-stance κ 0.160→0.346; foot contact mid-stance κ 0.700→0.854; timing of heel rise κ 0.769→0.835). The use of video analysis software is an efficient approach to improve the reliability of visual video assessments.
