The paper deals with a special sector of public procurement — G2G, in which state organizations act as both customers and suppliers. The analysis shows the convergence between contractual and administrative relations and risks of transferring the negative factors, responsible for market failures, into the administrative system, as well as the changing nature of the state organization. Budget losses in the sector G2G are revealed and estimated. There are doubts, whether the current practice of substitution of market-based instruments for administrative requirements is able to maintain integrity of public procurement in the situation of growing strategic challenges. Measures are proposed for the adjustment and privatization of contractual relations.

This paper applies techniques of demographic analysis to official data of Greece to obtain net migration estimates by age, sex and citizenship for the intercensal period 1991-2001. It is found that the overall net immigration rate for the decade is 6.3 per 100 resident population and the contribution of foreign immigrants to this figure is 88.2 per cent. 85.4 % of the net immigrants are of working age and 70.3 % of net immigrant women are of reproductive age. The results of the study can be used to formulate assumptions regarding the migration component when handling population estimates and projections.

This chapter discusses governance dilemmas that are often overlooked in studies that do not encompass the ecology of organization in public governance. The chapter discusses how coordination structures may counteract each other in multilevel systems of government. The ambition of the chapter is twofold: Firstly, a coordination dilemma is theoretically and empirically illustrated by the seeming incompatibility between a more direct (interconnected) and sectorally specialized implementation structure in the multilevel EU administrative system and trends towards strengthening coordination and control within nation states. Secondly, the chapter discusses organizational arrangements that may enable governance systems to live with the coordination dilemma in practice. This coordination dilemma seems to have been largely ignored in the literature on EU network governance and national ‘joined-up government’ respectively.

Genetic influences are often misinterpreted to mean that an individual with a particular genotype is inevitably predisposed to engage in a given behavior or that genetic influences operate outside of human agency and social context. This chapter undertakes a qualitative investigation of a genetically informed (MAOA) sample to illustrate the critical differences between population estimates and individual accountability. The sample includes those whose lives have revolved around violence (e.g., gang members) and those whose lives are committed to peace (e.g., Buddhist monks). It is found that genotype alone cannot predict any one individual’s social behaviors, and it is argued that any decisions or legal precedents targeted toward predicting how a specific individual may act based on his or her DNA sequence require a more nuanced appreciation of how social factors, genetic dispositions, and personal experience intertwine in the context of human agency.

AbstractEffective management of the threatened Antillean manatee (Trichechus manatus manatus) in Puerto Rico requires reliable estimates of population size. Estimates are needed to assess population responses to management actions, and whether recovery objectives have been met. Aerial surveys have been conducted since 1976, but none adjusted for imperfect detection. We summarize surveys since 1976, report on current distribution, and provide population estimates after accounting for apparent detection probability for surveys between June 2010 and March 2014. Estimates in areas of high concentration (hotspots) averaged 317 ± 101, three times higher than unadjusted counts (104 ± 0.56). Adjusted estimates in three areas outside hotspots also differed markedly from counts (75 ± 9.89 versus 19.5 ± 3.5). Average minimum island-wide estimate was 386 ± 89, similar to the maximum estimate of 360 suggested in 2005, but fewer than the 700 recently suggested by the Puerto Rico Manatee Conservation Center. Manatees were more widespread than previously understood. Improving estimates, locally or island-wide, will require stratifying the island differently and greater knowledge about factors affecting detection probability. Sharing our protocol with partners in nearby islands (e.g., Cuba, Jamaica, Hispaniola), whose populations share genetic make-up, would contribute to enhanced regional conservation through better population estimates and tracking range expansion.El manejo efectivo del manatí antillano amenazado en Puerto Rico requiere estimados de tamaños de poblaciónes confiables. Dichas estimaciones poblacionales son necesarias para evaluar las respuestas a las acciones de manejo, y para determinar si los objetivos de recuperación han sido alcanzados. Se han realizado censos aéreos desde 1976, pero ninguno de ellos han sido ajustados para detecciones imperfectas. Aquí resumimos los censos desde 1976, actualizamos la distribución, y reportamos los primeros estimados poblacionales ajustados para la probabilidad de detección aparente en los censos de Junio 2010 a Marzo 2014. Las estimaciones poblacionales en áreas de mayor concentración del manatí promedió 317 ± 103, tres veces más abundante que los conteos sin ajuste (104 ± 0.56). Las estimaciones poblacionales en tres áreas fuera de las áreas de mayor concentración del manatí también fueron marcadamente diferentes (75 ± 9.89 vs 19.5 ± 3.5). El estimado mínimo poblacional en la isla entera fue de 386 ± 89, similar al estimado máximo de 360 sugerido en el año 2005, pero menor a los 700 sugeridos recientemente por el Centro de Conservación de Manatíes de Puerto Rico. Documentamos que el manatí tiene una distribución más amplia de lo que se sabía con anterioridad. El mejoramiento de los estimados poblacionales locales o a nivel de isla requerirá que se estratifique a la isla en forma diferente y que se investiguen los factores que influencian a la probabilidad de detección. Compartir protocolos como este con colaboradores de islas vecinas (por. ej., Cuba, Jamaica, Española), cuyas poblaciones de manatíes comparten material genético, contribuiría a la conservación regional mediante mejores estimaciones poblacionales y monitoreo de la expansión de su ámbito doméstico.
