Assessing dynamics of forced livestock movements, livelihoods and future development options for pastoralists/agro-pastoralists in Ruvuma and Lindi Regions, in the Southern Tanzania

The study that aimed at understanding the dynamics of forced livestock movements and pastoral livelihood and development options was conducted in Lindi and Ruvuma regions, using both formal and informal approaches. Data were collected from 60 randomly selected Agro-pastoralists/Pastoralists and native farmers using a structured questionnaire. Four villages were involved; two in Lindi region (Matandu and Mkwajuni) and the other two in Ruvuma region (Gumbiro and Muhuwesi). Data were analyzed using descriptive statistics of SPSS to generate means and frequencies. The results indicate that a large number of animals moved into the study area following the eviction order of the government in Ihefu wetlands in 2006/2007. Lindi region was earmarked by the government to receive all the evicted pastoralists. However, by 2008 only 30% of the total cattle that were expected to move into the region had been received. Deaths of many animals on transit, selling of the animals to pay for transportation and other costs while on transit and many pastoralists settling in Coastal and Ruvuma regions before reaching their destinations were reported to be the reasons for the discrepancy observed. To mitigate anticipated conflicts between farmers and pastoralists, Participatory Land Use Management (PLUM) plans were developed in all the study villages in order to demarcate village land area into different uses, including grazing, cropping, settlement and forests. Land units for grazing were supposed to be provided with all necessary livestock infrastructures (dips, charcoal dams, livestock markets and stock routes). However, the land use plans were not able to prevent the anticipated conflicts because most of the livestock infrastructures were lacking, the land use boundaries were not clearly demarcated and there was limited enforcement of village by-laws, since most had not been enacted by the respective district councils. Similarly, the areas allocated for grazing were inadequate for the number of livestock available and thus the carrying capacity exceeded. Thus, land resource-based conflicts between farmers and pastoralists were emerging in the study areas for the reason that most of the important components in the PLUM plans were not in place. Nevertheless, the arrival of pastoralists in the study areas had positive effects on food security and growth of social interactions between pastoralists and farmers including marriages between them. Environmental degradations due to the arrival of livestock were also not evident. Thus, there is a need for the government to purposely set aside enough grazing land with all necessary infrastructures in place for the agro-pastoral/pastoral communities in the country.

The Territoriality of Fiscal Solidarity: Comparing Swiss Equalisation with European Union Structural Funding

This article theorises the territorial solidarity and fiscal federalism and compares Switzerland with the European Union. While inter-territorial solidarity is a prerequisite for legitimate fiscal equalisation, such equalisation in turn also contributes to the legitimacy of and solidarity within federal political systems. By cutting across territorial and ethno-national communities, fiscal transfers often contribute to both a “civic” sense of belonging and a “cosmopolitan” identity. After placing types and degrees of (inter-)territorial solidarity at the heart of our conceptual perspective, we discuss the effects of such solidarity through an analysis of two different forms of “federal” equalisation. Comparing the recently reformed Swiss fiscal equalisation system with the EU structural funds allows us to infer if, and how, the fiscal dimension of federalism matters for feelings of solidarity, reciprocity, unity and, ultimately, for the legitimacy of the very (nation-state or Union) structures that are to contribute to the ever-growing prosperity and happiness of their people(s). In Switzerland, a civic understanding of nationhood and cross-cutting cleavages were necessary conditions for extensive, effective and legitimate fiscal equalisation. We infer that, for the EU, this means that strengthening the equalisation component of the structural funds would contribute to an ever closer Union in a political sense: because fiscal equalisation and inter-territorial solidarity are interdependent, reinforcing the one also means cementing the other. Future studies of the EU and federal-type arrangements are advised to pay more explicit attention to the solidarity-element of territoriality – or the territoriality of (fiscal) solidarity.

Functional error modeling for uncertainty quantification in hydrogeology

Approximate models (proxies) can be employed to reduce the computational costs of estimating uncertainty. The price to pay is that the approximations introduced by the proxy model can lead to a biased estimation. To avoid this problem and ensure a reliable uncertainty quantification, we propose to combine functional data analysis and machine learning to build error models that allow us to obtain an accurate prediction of the exact response without solving the exact model for all realizations. We build the relationship between proxy and exact model on a learning set of geostatistical realizations for which both exact and approximate solvers are run. Functional principal components analysis (FPCA) is used to investigate the variability in the two sets of curves and reduce the dimensionality of the problem while maximizing the retained information. Once obtained, the error model can be used to predict the exact response of any realization on the basis of the sole proxy response. This methodology is purpose-oriented as the error model is constructed directly for the quantity of interest, rather than for the state of the system. Also, the dimensionality reduction performed by FPCA allows a diagnostic of the quality of the error model to assess the informativeness of the learning set and the fidelity of the proxy to the exact model. The possibility of obtaining a prediction of the exact response for any newly generated realization suggests that the methodology can be effectively used beyond the context of uncertainty quantification, in particular for Bayesian inference and optimization.

Service Brand Relationship Quality: Hot or Cold?

Customers’ long-term brand relations are crucial drivers of a service brand’s sustainable competitive advantage. This research empirically examines the quality of customer-service brand relationships in the context of an airline’s frequent flyer program. The authors show that service brand relationship quality (BRQ) involves both a hot (based on emotions) and a cold (based on objectrelevant beliefs) component. They find that these two components have different implications for a service brand’s performance and are at least partially driven by different antecedents whose relative importance changes over time. Specifically, cold BRQ is important for word-of-mouth behavior and is strongly driven by partner quality (i.e., the generalized assessment of the brand in its role as a relationship counterpart). Hot BRQ, on the other hand, has a stronger impact on willingness to pay a price premium and consideration set size. In early stages of a customer-brand relationship hot BRQ is more strongly driven by self-congruence (i.e., consumer’s perception of the fit between his/her self and the brand’s personality), in later stages partner quality becomes more relevant. The authors discuss the implications of their findings for the development of BRQ and the implementation of alternative growth strategies in a services context.

Bruch oder Konstante? : Zum Verhältnis von Humangenetik und Eugenik im 20. Jahrhundert

Die Geschichte der Humangenetik stellte lange Zeit ein vernachlässigtes Gebiet der medizin- und wissenschaftshistorischen Forschung dar. Erst in jüngster Vergangenheit sind einige historische Arbeiten erschienen, die sich der Geschichte dieses medizinischen Forschungs- und Praxisfeldes widmen. Eine wichtige Forschungsfrage betrifft die Beziehung der Humangenetik zur Eugenik. Der vorliegende Beitrag greift diese Frage auf und zeigt anhand eines Schweizer Fallbeispiels zur Vererbung des Kropfes, dass zwischen der Humangenetik und der Eugenik im 20. Jahrhundert enge, aber auch widersprüchliche Beziehungen bestanden: Ergebnisse aus Vererbungsstudien widersprachen nicht selten eugenischen Postulaten, zugleich konnten aber dieselben humangenetischen Untersuchungen Visionen einer erbbiologischen Bevölkerungsüberwachung befeuern.

The Economic Case for Fiscal Federalism in Scotland

In this paper we consider the case for assigning tax revenues to Scotland, by which we mean that taxes levied on Scottish tax bases should be returned to the Scottish budget. The budget, however, would continue to be supplemented by transfers from the Westminster budget. This arrangement differs from the current situation whereby public spending is largely financed by a bloc grant from Westminster. Our suggestion falls short of full fiscal federalism for Scotland . meaning that Scotland had control over choice of tax base and of tax rates, and fiscal transfers from Westminster would be minimal. We use propositions drawn from the theory of fiscal federalism to argue for a smaller vertical imbalance between taxes retained in Scotland and public spending in Scotland. A closer matching of spending with taxes would better signal to beneficiaries the true costs of public spending in terms of taxes raised. It would also create more complete incentives for politicians to provide public goods and services in quantities and at qualities that voters are actually willing to pay for. Under the current bloc grant system, the marginal tax cost of spending does not enter into political agents. calculations as spending is out of a fixed total budget. Moreover, the Scottish electorate is hindered in signaling its desire for local public goods and services since the size of the total budget is determined by a rigid formula set by Westminster. At the present time we reject proposals for full fiscal federalism because in sharply reducing vertical imbalance in the Scottish budget, it is likely to worsen horizontal balance between Scotland and the other UK regions. Horizontal balance occurs where similarly situated regions enjoy the same per capita level of public goods and services at the same per capita tax cost. The complete removal of the bloc grant under full fiscal federalism would remove the mechanism that currently promotes horizontal equity in the UK. Variability in own-source tax revenues creates other problems with full fiscal federalism. Taxes derived from North Sea oil would constitute a large proportion of Scottish taxes, but these are known to be volatile in the face of variable oil prices and the pound-dollar exchange rate. At the present time variability in oil tax revenue is absorbed by Westminster. Scotland is insulated through the bloc grant. This risk sharing mechanism would be lost with full fiscal federalism. It is true that Scotland could turn to financial markets to tide itself over oil tax revenue downturns, but as a much smaller and less diversified financial entity than the UK as a whole it would probably have to borrow on less favorable terms than can Westminster. Scotland would have to bear this extra cost itself. Also, with full fiscal federalism it is difficult to see how the Scottish budget could be used as a macroeconomic stabilizer. At present, tax revenue downturns in Scotland - together with the steady bloc grant - are absorbed through an increase in vertical imbalance. This acts as an automatic stabilizer for the Scottish economy. No such mechanism would exist under full fiscal federalism. The borrowing alternative would still exist but on the less favorable terms - as with borrowing to finance oil tax shortfalls.

Achieving Universal Primary Education: Can Kenya Afford it?

Kenya has experienced a rapid expansion of the education system partly due to high government expenditure on education. Despite the high level of expenditure on education, primary school enrolment has been declining since early 1990s and until 2003 when gross primary school enrolment increased to 104 percent after the introduction of free primary education. However, with an estimated net primary school enrolment rate of 77 percent, the country is far from achieving universal primary education. The worrying scenario is that the allocations of resources within the education sector seems to be ineffective as the increasing expenditure on education goes to recurrent expenditure (to pay teachers salaries). Kenya's Poverty Reduction Strategy Paper (PRSP) and the Economic Recovery Strategy for wealth and Employment Creation (ERS) outlines education targets of reaching universal primary education by 2015. The Government is faced with budget constrains and therefore the available resources need to be allocated efficiently in order to realize the education targets. The paper uses Budget Negotiation Framework (BNF) to analyze the cost effective ways of resource allocation in the primary education sector to achieve universal primary education and other education targets. Budget Negotiation Framework is a tool that aims at achieving equity and efficiency in resource allocation. Results from the analysis shows that universal primary education by the year 2015 is a feasible target for Kenya. The results also show that with a more cost- effective spending of education resources - increased trained teachers, enhanced textbook supplies and subsidies targeting the poor - the country could realize higher enrolment rates than what has been achieved with free primary education.

The impact of functional impairment on the survival of patients with Alzheimer's disease

Alzheimer's disease (AD), the most common form of dementia, is the fifth leading cause of death among U.S. adults aged 65 or older. Most AD patients have shorter life expectancy compared with older people without dementia. This disease has become an enormous challenge in the aging society and is also a global problem. Not only do families of patients with Alzheimer's disease need to pay attention to this problem, but also the healthcare system and society as a whole have to confront. In dementia, functional impairment is associated with basic activities of daily living (ADL) and instrumental activities of daily living (IADL). For patients with Alzheimer's disease, problems typically appear in performing IADL and progress to the inability of managing less complex ADL functions of personal care. Thus, assessment of ADLs can be used for early accurate diagnosis of Alzheimer's disease. It should be useful for patients, caregivers, clinicians, and policy planners to estimate the survival of patients with Alzheimer's disease. However, it is unclear that when making predictions of patient outcome according to their histories, time-dependent covariates will provide us with important information on how changes in a patient's status can effect the survival. In this study, we examined the effect of impaired basic ADL as measured by the Physical Self-Maintenance Scale (PSMS) and utilized a multistate survival analysis approach to estimate the probability of death in the first few years of initial visit for AD patients taking into consideration the possibility of impaired basic ADL. The dataset used in this study was obtained from the Baylor Alzheimer's Disease and Memory Disorders Center (ADMDC). No impaired basic ADL and older age at onset of impaired basic ADL were associated with longer survival. These findings suggest that the occurrence of impaired basic ADL and age at impaired basic ADL could be predictors of survival among patients with Alzheimer's disease. ^

Patients' preferences for a prostate cancer consultation, a discrete choice experiment

Four basic medical decision making models are commonly discussed in the literature in reference to physician-patient interactions. All fall short in their attempt to capture the nuances of physician-patient interactions, and none satisfactorily address patients' preferences for communication and other attributes of care. Prostate cancer consultations are one setting where preferences matter and are likely to vary among patients. Fortunately, discrete choice experiments are capable of casting light on patients' preferences for communication and other attributes of value that make up a consultation before the consultation occurs, which is crucial if patients are to derive the most utility from the process of reaching a decision as well as the decision itself. The results of my dissertation provide strong support to the notion that patients, at least in the hypothetical setting of a DCE, have identifiable preferences for the attributes of a prostate cancer consultation and that those preferences are capable of being elicited before a consultation takes place. Further, patients' willingness-to-pay for the non-cost attributes of the consultation is surprisingly robust to a variety of individual level variables of interest. ^

Physician attitudes on the HPV vaccine

The quadrivalent HPV vaccine was developed primarily for the prevention of cervical cancer. The vaccine, originally approved for females, was recently approved by the American Committee for Immunization Practices to be administered to males, allowing federal programs to pay for the vaccination for both males and females. However, uptake for this vaccination has been low. Studies show that physicians have great influence over whether or not parents decide to vaccinate their children. In this study, a survey was mailed out asking physicians about their attitude towards the HPV vaccination and what they believed to be the barriers to the vaccination of their patients. The analysis of the data included descriptive statistics and chi-square analysis in order to compare the differences in responses between male and female patients. The vast majority of physicians supported the vaccination of both females and males. However, the perceived barriers to vaccinating females differed from males, with physicians believing that parents' concern about sexual promiscuity was a greater barrier to vaccination in girls than boys (p=0.007). The other major significant difference in perceived barriers among physicians is the belief that physicians in general are less likely to promote the vaccination in males compared to females (p=0.01). Despite evidence to the contrary, it seems more patient education is needed regarding sexual promiscuity and its association with the HPV vaccine. There may also be a need for increased physician education regarding the use of the HPV vaccine for male patients.^

The wine hedonic price models in the "Old and New World": : state of the art

The basic hedonic hypothesis is that goods are valued for their utility-bearing characteristics and not for the good itself. Each attribute can be evaluated by consumers when making a purchasing decision and an implicit price can be identified for each of them. Thus, the observed price of a certain good can be analyzed as the sum of the implicit prices paid for each quality attribute. Literature has reported hedonic models estimates in the case of wines, which are excellent examples of differentiated goods worldwide.The impact of different wine attributes (intrinsic or extrinsic) on consumers’ willingness to pay has been analyzed with dissimilar results. Wines coming from "New World" producers seem to be appreciated for different attributes than wines produced in the "Old World". Moreover, "Old and New World" consumers seem to value differently the wine’s characteristics. To our knowledge, no cross country analysis has been done dealing with "New World" wines in "Old World" countries, leaving an important gap in understanding underlying attributes influencing buying decisions.

La educación, base para el desarrollo y la seguridad a escala humana

Las teorías sobre el desarrollo son en realidad un dinámico debate acerca de la relación población/recursos, de las condiciones de inequidad a escala planetaria y al interior de las naciones, y de las formas de superarlas. Para avanzar hacia el desarrollo humano, es prioritario enfocar las acciones en la superación de las carencias que afectan la situación personal de los ciudadanos y eliminar los obstáculos que impiden su bienestar en relación con las condiciones medioambientales en las que transcurre su vida. La educación es comprendida como el eje fundamental para alcanzar niveles de desarrollo aceptables, asegurando superar situaciones de exclusión social. Sobre la base de encuestas en cuatro establecimientos educativos del Gran Mendoza, se analizan las relaciones existentes entre las representaciones, de los adolescentes y sus familias sobre la importancia de la educación como medio optimizador de las situaciones socioeconómicas y los proyectos de capacitación futura, tanto a nivel terciario como universitario.

Políticas públicas ante el cambio climático en un contexto de crecimiento económico : Construcción de una agencia estatal para paliar las inundaciones en la provincia de Buenos Aires, 1870-1910

Aunque son conocidos los recurrentes ciclos de sequías e inundaciones que desde la segunda mitad del siglo XIX ha padecido la provincia de Buenos Aires, todavía se debaten las mejores soluciones para el problema de la abundancia de agua, debido a los cuantiosos daños materiales que ocasiona a las empresas agroganaderas. Sin embargo, esta cuestión no ha concitado el interés de los historiadores, y salvo algunas excepciones, menos atención se ha prestado al manejo de los recursos hídricos por parte de Estado provincial. Nos proponemos estudiar la participación de la agencia estatal en el presupuesto provincial puesto que indica la inversión pública, y ponderar el aporte privado toda vez que se compelía a los propietarios a pagar un impuesto especial. Nuestro período se extiende desde la década de 1870 hasta 1910 en que, estimamos, se cierra un primer ciclo de intervenciones estatales en la cuestión de las inundaciones. Enfocaremos el análisis a través de los registros oficiales, y los mensajes de los gobernadores

Violencia y poder : Crímenes sexuales en Buenos Aires, 1850-1860

Este trabajo busca introducir al lector en una problemática tan antigua como actual: el de los crímenes sexuales, proponiéndo un acercamiento múltiple desde la visión jurídica y la social, desde las víctimas y su familia. Nos hemos concentrado especialmente en tratar de observar la violencia sexual jurídica que define a la víctima según su sexo, "cualidad moral" y el acto que se cometiera sobre ella, que le niega el derecho a reclamar, adoctrinando en el silencio como mejor opción que la denuncia. También nos propusimos mostrar como hay personas que desafiando este "disciplinamiento" busca el castigo del o los culpables del delito sabiendo sin embargo que existe un precio muy alto que pagar por ello: la deshonra pública de una hija o hijo

Estructura y dinámica del dominio de Santo Toribio de Liébana : Siglos XIII-XVI

En "Estructura y dinámica del dominio de Santo Toribio de Liébana (siglos XIII-XVI)" se trata de explicar las características diferenciales que presenta un dominio monástico del área septentrional de la Península Ibérica. En la primera parte, siglo XIII y principios del siglo XIV, se considera que la pobreza material que ostenta el cenobio, observable en el escaso volumen de la renta y en las sucesivas enajenaciones de bienes efectuadas por sectores jerarquizados locales, es el resultado de la dispar consolidación de las estructuras feudales en el espacio. Frente a áreas cercanas al emplazamiento del monasterio en donde el señor limita la movilidad campesina y extrae excedentes elevados y estables, existen otras, consideradas como la "periferia" del dominio, en donde la pervivencia del ejercicio del derecho de retorno limitaba seriamente la consolidación de la propiedad dominical señorial. En dichas áreas, la estabilización de los derechos de propiedad del señor sólo se concretó a partir de la conformación de estructuras coercitivas de poder a nivel local que anularon el ejercicio efectivo del retorno familiar. En la segunda parte, siglos XIV-XVI, se analizan las estrategias específicas que permitieron el incremento del volumen de la renta en el largo plazo. Frente a las tesis que sostienen una temprana parcelación de la reserva y una conmutación de las prestaciones de trabajo, se observa aquí, por el contrario, el aumento de su extensión en los siglos finales de la Edad Media. Al mismo tiempo se detecta un proceso de parcelación de las tenencias campesinas, impulsado por el señor, que propiciaba un incremento de los fuegos sobre los que recaían las exacciones. Ambos aspectos, apropiación señorializada del espacio y aumento de la tasa de la renta, fueron el resultado del ejercicio efectivo de la coacción política.
