Stanje in razvoj gozdov Kartuzije Pleterje

Na podlagi arhivskih virov lastnika posesti, podatkov Zavoda za gozdove Slovenije ter informacijskega sistema Silva-Si je bilo analizirano gospodarjenje in razvoj gozdov na posesti kartuzije Pleterje za obdobje 1933-2008. Podrobneje so bili analizirani naslednji izbrani sestojni in gospodarski znaki: lesna zaloga, prirastek, debelinska struktura, drevesna sestava, etat, posek in izvedena gojitvena dela. Lastniki gozdne posesti so seskozi zgodovino menjavali, zato je bilo preteklo gospodarjenje zelo različno, kar se kaže v velikih spremembah sestojnih znakov v preučevanem obdobju in sedanjem stanju gozdov.Based on three main data resources, forest estate owners, Slovenian forest service and information system Silva-Si, state, development and previous management of Pleterje Charterhouse\u27s Forest in the period 1933-2008 were analyzed. Changes in forest stands and management were determined with specific indicators: growing stock, increment, diameter structure, species composition, realised fellings, allowable cut and realised silvicultural work. In the past owners of forest estate were changing, so the management was very different, which resulteds in a large change of state parameters and the current state of forests

The symptoms of adult chronic and acute Leukaemia before diagnosis: Large primary care case-control studies using electronic records

Background: Leukaemia is the eleventh commonest UK cancer. The four main sub-types have different clinical profiles, particularly between chronic and acute types. Aim: To identify the symptom profiles of chronic and acute leukaemia in adults in primary care. Design and setting: Matched case-control studies using Clinical Practice Research Datalink records. Methods: Putative symptoms of leukaemia were identified in the year before diagnosis. Conditional logistic regression was used for analysis; to estimate risk, positive predictive values (PPVs) were calculated, using Bayes� theorem Results: 4,655 cases were available aged �40 years, diagnosed between 2000 and 2009, with 2,877 being chronic leukaemia (CL), 937 acute leukaemia (AL) and 841 of unreported subtype, with 20,719 age, sex and practice-matched controls. The two studies examined CL and AL separately. Ten symptoms were independently associated with CL, the three strongest associations being for: lymphadenopathy, odds ratio 22 (95% confidence interval 13,36), weight loss 3.0 (2.1,4.2) and bruising 2.3 (1.6,3.2). Thirteen symptoms were independently associated with AL, the three strongest being: nosebleeds and/or bleeding gums 5.7 (3.1,10), fever 5.3 (2.7,10) and fatigue 4.4 (3.3,6.0). Infection was reported frequently in both AL and CL, but the associations were small. No individual symptom or combination of symptoms had a PPV >1%. Conclusions: The symptom profiles of CL and AL have both overlapping and distinct features. This presents a dichotomy for GPs: diagnosis, by performing a full blood count, is easy; however, the symptoms of leukaemia are non-specific and of relatively low risk. This explains why many leukaemia diagnoses are unexpected findings

Measuring educational efficiency at student level with parametric stochastic distance functions: an application to Spanish PISA results

The aim of the present paper is to examine the observed differences in Students’ test performance across public and private‐voucher schools in Spain. For this purpose, we explicitly consider that education is a multi‐input multi‐output production process subject to inefficient behaviors, which can be identified at student level using a parametric stochastic distance function approach. The empirical application of this model, based on Spanish data from the Programme for International Student Assessment implemented by the Organization for Economic Co‐operation and Development in 2003, allows us to identify different aspects of the underlying educational technology. Among other things, the results provide insights into how student background, peer group, school characteristics and personal circumstances interact with educational outputs. Moreover, our findings suggest that, once educational inputs and potential bias due to school choice endogeneity are taken into account, no further unexplained difference remains between students’ efficiency levels across public and private‐voucher schools.public schools, educational efficiency, stochastic frontier, distance function,
