Dokumentarzyści i krytyk. Zygmunt Kałużyński a dokumentaliści „nowej zmiany”
No full textThe article offers the analysis of how Zygmunt Kałużyński, the film critic of Polityka weekly magazine, described and stigmatized documentary films by Krzysztof Kieślowski, Tomasz Zygadło, Grzegorz Królikiewicz and Krzysztof Gradowski presented at the Cracow short film festival in 1971. Kałużyński criticized and mocked the aesthetics of the Polish “new wave” documentary cinema in a series of articles published in Spring and Summer of 1971. He presented films by brave and talented directors, contradicting the current social and political situation, as the unreflective imitation of the banal television documentary style based on in-front-of-the-camera interviews. The author compares Kałużyński’s proceedings to actions of a British journalist Robert Pitmann described by Tadeusz Różewicz in his essay A Journalist and the Poet. Pitmann conducted a sneering interview with T.S. Eliot for Sunday Express in 1958 and Różewicz comments on the possible effects of his text for its readers.The article offers the analysis of how Zygmunt Kałużyński, the film critic of Polityka weekly magazine, described and stigmatized documentary films by Krzysztof Kieślowski, Tomasz Zygadło, Grzegorz Królikiewicz and Krzysztof Gradowski presented at the Cracow short film festival in 1971.

Multivariate nonparametric tests for independence
No full textMultivariate generalizations of Bhuchongkul's bivariate rank statistics [Ann. Math. Statist.35 (1964)] have been introduced and studied in this paper for the purpose of testing mulitvariate independence. It is shown that the test statistics can be expressed as rank statistics which are easy to compute, have asymptotic normal distributions, and can detect mutual dependence in alternatives which are pairwise independent. The tests are compared to the Puri-Sen-Gokhale [[8]] tests and a normal theory test [ [1]] using Pitman efficiency.Tests of independence empirical distribution function ranks consistency Bahadur efficiencies Pitmann efficiencies
Statistical fractal inference
No full textThe inverse power law distributions are used as the model for fractal probability distributions that have fractional exponents (λ) and such that the transformation X(1-λ) is uniformly distributed. The paper examines aspects of point estimation and tests of hypotheses about statistical fractals. It is shown that the maximum likelihood estimator of the fractional dimension λ is uniformly minimum variance unbiased estimator (UMVUE) using the Lehmann-Scheffe’s theorem and also that the likelihood ratio test for H0: λ= λ0 is uniformly most powerful (UMPT) by the Neymann-Pearson Lemma. The paper likewise explains that the test for equality of two medians of two fractal distributions is equivalent to a test for the equality of the fractal dimensions. In fact, the result is generalized to the test for the equality of two αth quantiles of two fractal distributions. The test for the equality of two fractal distributions is compared with the Mann-Whitney U test and with the Student’s t-test for independent samples in terms of robustness and asymptotic Pitmann efficiency
Environment and economic efficiency: an analysis of some polluting Italian industries
No full textthis research presents an extension of the directional distance function model to measure performances for firms which produce a large number of pollutants and operate in different industrial sectors. I use this methodology to estimate productivity indexes on a sample of Italian firms that were forced to declare their emissions to the European Pollution Release and Transfer Register in 2007. A proxy for the environmental regulation’s cost is derived and results show a significant impact in term of potential value added lost. Estimations also reveal differences in mean environmental performances among industries; furthermore, the effect of pollution control follows the same path.Directional distance function, Environmental regulation, Polluting industries
Site 1215
No full textSite 1215 (26°01.77´N, 147°55.99´W, 5396 meters below sea level [mbsl]; Fig. F1) is the northernmost of seven sites drilled on the 56-Ma-crust transect during Ocean Drilling Program (ODP) Leg 199. It will be used to investigate paleoceanographic processes in the northern subtropical early Eocene Pacific Ocean. Site 1215 is situated north of the Molokai Fracture Zone on typical abyssal hill topography in an area of thin but continuous sediment cover (Fig. F2). Based on magnetic lineations, basement age at Site 1215 should be in the youngest part of Anomaly An26R, or ~58 Ma (Cande et al., 1989; timescale of Cande and Kent, 1995). The Cenozoic history of sedimentation in this region was poorly constrained prior to Leg 199 drilling because the nearest Deep Sea Drilling Project (DSDP) or ODP drill site (DSDP Leg 5) is >1000 km away. Based on data from these early rotary coring activities (together with magnetic anomaly maps, a program of shallow-penetration piston coring, and seismic profiling), we expected the sedimentary sequence at Site 1215 to comprise red clays (a mixture of wind-blown dust and authigenic precipitates) overlying a basal carbonate section deposited when the site was near the ridge crest in the late Paleocene and early Eocene.
The broad paleoceanographic objectives of drilling the sedimentary sequence anticipated at Site 1215 are as follows: (1) to help define the shift in the Intertropical Convergence Zone through the Paleogene by following the change in eolian-dust composition and flux through time (red clays); (2) to help define the North Equatorial Current and North Pacific subtropical gyre processes (basal carbonates); and (3) sampling of the Paleocene/Eocene (P/E) boundary, one of the most climatologically critical intervals of Cenozoic time. Recovery of deep-sea sediments from this time interval was a high priority because the P/E boundary has never been sampled in the central tropical Pacific Ocean.
Results from Site 1215 will also provide important information to test whether there was significant motion of the Hawaiian hotspot, with respect to the Earth's spin axis, during the early Cenozoic. At 56 Ma, the backtracked location based upon a hotspot reference frame (Gripp and Gordon, 1990, for 0- to 5-Ma Pacific hotspot rotation pole; Engebretson et al., 1985, for older poles) is ~11°N, 117°W. If significant hotspot motion or true polar wander occurred since 57 Ma (Petronotis et al., 1994), this drill site could have been much closer to the equator
A computational model of the referential semantics of projective prepositions
No full textIn this paper we present a framework for interpreting locative expressions containing the prepositions in front of and behind. These prepositions have different semantics in the viewer-centred and intrinsic frames of reference (Vandeloise, 1991). We define a model of their semantics in each frame of reference. The basis of these models is a novel parameterized continuum function that creates a 3-D spatial template. In the intrinsic frame of reference the origin used by the continuum function is assumed to be known a priori and object occlusion does not impact on the applicability rating of a point in the spatial template. In the viewer-centred frame the location of the spatial template’s origin is dependent on the user’s perception of the landmark at the time of the utterance and object
occlusion is integrated into the model. Where there is an ambiguity with respect to the intended frame of reference, we define an algorithm for merging the spatial templates from the competing frames of reference, based on psycholinguistic observations in (Carlson-Radvansky, 1997)

Leg 199 summary
No full textOcean Drilling Program (ODP) Leg 199, "The Paleogene Equatorial Transect" (Sites 1215-1222), was designed to study the evolution of the equatorial Pacific current and wind system as Earth went from maximum Cenozoic warmth to initial Antarctic glaciations. The drilling program was primarily devoted to a transect along the 56- to 57-Ma crust, old enough to capture the Paleocene/Eocene boundary in the basal, more carbonate-rich sediments. The Leg 199 transect extends from a paleolatitude of ~4°N- ~4°S to encompass a relatively thick lower Eocene sediment section perhaps 8° north of the paleoequator. One site (1218) was also drilled on ~40-Ma crust to collect a near-equatorial sediment sequence from the middle Eocene to the Oligocene in order to investigate the transition in global climate from the Eocene "greenhouse" to Oligocene "icehouse." The Pacific plate has drifted northward through Cenozoic time transporting biogenic sediments deposited under the high-productivity equatorial belt into a zone of extremely slow sediment (red clay) accumulation. Thus, the central tropical North Pacific Ocean is an ideal region in which to sample shallowly buried Paleogene sequences of equatorially deposited biogenic sediments. The thin Neogene cover of red clay in the area means that the entire Paleogene sediment section is potentially drillable by ODP advanced piston coring and extended core barrel methods
The Diagnostic Value of MRI Pattern Recognition in Distal Myopathies
No full textObjective: Distal myopathies are a diagnostically challenging group of diseases. We wanted to understand the value of MRI in the current clinical setting and explore the potential for optimizing its clinical application.
Methods: We retrospectively audited the diagnostic workup in a distal myopathy patient cohort, reassessing the diagnosis, whilst documenting the usage of MRI. We established a literature based distal myopathies MRI pattern template and assessed its diagnostic utility in terms of sensitivity, specificity, and potential impact on the diagnostic workup.
Results: Fifty-five patients were included; in 38 with a comprehensive set of data the diagnostic work-up was audited. The median time from symptoms onset to diagnosis was 12.1 years. The initial genetic diagnostic rate was 39%; 18% were misdiagnosed as neuropathies and 13% as inclusion body myositis (IBM). Based on 21 publications we established a MRI pattern template. Its overall sensitivity (50%) and specificity (32%) were low. However in some diseases (e.g., MYOT-related myopathy, TTN-HMERF) MRI correctly identified the causative gene. The number of genes suggested by MRI pattern analysis was smaller compared to clinical work up (median 1 vs. 9, p < 0.0001) but fewer genes were correctly predicted (5/10 vs. 7/10). MRI analysis ruled out IBM in all cases.
Conclusion: In the diagnostic work-up of distal myopathies, MRI is useful in assisting genetic testing and avoiding misdiagnosis (IBM). The overall low sensitivity and specificity limits its generalized use when traditional single gene test methods are applied. However, in the context of next generation sequencing MRI may represent a valuable tool for interpreting complex genetic results
