Bureaucratic institutional design: the case of the Italian NHS

We propose a model where a regional government’s choice of the number of bureaucratic agencies operating in a region depends upon the degree of substitutability and complementarity of the bureaucratic services being demanded. We show that, if the government perceives the citizens’ demand as a demand for substitutable services, it will choose provision by two independent agencies. If the government perceives the citizens’ demand as a demand for complementary services, it will choose provision by a single consolidated agency. Exogenous shocks to the number of citizens amplify these incentives. Evidence from the Italian National Health Service (NHS) supports this hypothesis. Results show a positive effect of proxies of substitutable services on the number of regional local health authorities and a negative effect of proxies of complementary services. The major immigration amnesties, taken as shocks to the number of citizens entitled to the service, magnify these effects.     

Classwork and homework in early adolescence: The ecology of achievement

Recent studies have questioned whether the nation's educational system is adequately preparing children to function productively in today's society. To examine this issue, the present study utilized the Experience Sampling Method to investigate the amount of time young adolescents spent doing classwork and homework, their inner subjective experience while doing so, and their companions while doing homework. The relationship between these variables and students' academic performance was also examined. Results revealed that students spent only 15.5 hours per week engaged in school work and only 6 hours per week doing homework, with increased homework time associated with better academic achievement. In addition, students were found to complete homework primarily alone or in classes, although doing homework with their parents was associated with better academic performance. Lastly, students' affect was found to be relatively neutral when doing classwork, but comparatively more negative while doing homework, particularly when doing homework alone. The implications of these findings for understanding the socializing influence of school are discussed.This research was supported by NIMH grant number MH38324, Stress in Daily Life During Early Adolescence, awarded to Reed Larson. This paper was prepared while the first author was a Schmitt Dissertation Fellow at Loyola University of Chicago.Received her Ph.D. from Loyola University of Chicago, Current Research interest are familial and intrapsychic influences on adolescents' academic performance.Current Research interests are pubertal development, precursors of eating disorders, and the effect of maternal employment on young adolescents.     

The effect of exposure to the elements on the forensic characterization by infrared spectroscopy of poly(ethylene terephthalate) fibers

Validation of a recently proposed differentiation method for single poly (ethylene terephthalate) (PET) fibers, based on integration of IR absorption bands, is presented. IR microscopy in the transmission mode, differential scanning calorimetry and optical microscopy were employed. The reliability of the technique has been extended to the cases in which the fibers being compared have experienced long exposure to the elements, as may happen if these items are recovered from open-air crime scenes. The effect of immersion in water and irradiation by the sun for a three-month period have been considered. The fibers remained morphologically and structurally unaltered. The significance of comparisons between fibers kept in different environments is thus enhanced, because the detrimental effect of the elements can be ruled out. This further validation of the proposed technique contributes to render the data presented by the forensic scientist less vulnerable to context effect and bias.     

Employing glass refractive index measurement (GRIM) in fiber analysis: a simple method for evaluating the crystallinity of acrylics

The refractive index (RI) of 40 colorless acrylic fiber samples was determined by the immersion oil and Mettler hot stage method, implemented in the glass refractive index measurement (GRIM) instrument by Foster and Freeman. Low standard deviations for nearly all the samples were obtained and differentiation of fibers even with the same trade name was possible just on the basis of RI. Wide angle X-ray scattering (WAXS) and differential scanning calorimetry (DSC) were employed to establish a linear correlation between RI and the degree of crystallinity. Insights on the structural order of this group of fibers is then obtainable by a quick and easy technique, adding value to casework comparisons.     

Y chromosome J2 subtyping in an Italian sample: Population and forensic implications

In the recent years the Y chromosome genealogy has been refined by a number of newly discovered SNPs. The non-random distribution of the Y chromosome lineages worldwide makes fundamental the dissection and characterisation of haplogroups associated with specific geographic areas. In Southern Europe the haplogroup J2, as defined by the M172 marker, can reach frequencies up to 35%, making the dissection of such lineage critical for population studies. Here we present a study on J2 chromosomes from the Italian peninsula. Populations and forensic implications are discussed. A total of 900 individuals were previously genotyped for a number of SNPs, including M172. More than 200 of these have been now genotyped for 7 SNPs within the J2 lineage using a multiplex SNaPshot approach. The different distribution of the various lineages in different geographic areas probably reflects different historical demographic events and points to differential Y chromosome haplotype distribution, with implication for forensic application of this genetic marker.     

Brazilian National Identity at a Crossroads: The Myth of Racial Democracy and the Development of Black Identity

This article aims at coping with the 2003 implementation of affirmative action policies favoring blacks and “browns” in public-funded universities in Brazil. We are especially interested in coming to terms with some of the most resounding controversies over this type of “race”-based policy, which in our view are to be seen as reactions to some core aspects of Brazil’s national identity. The key question that has pervaded this debate is: Should the State apparatus, by means of these non-universalist policies, foster racial identities in a society that has historically imagined itself as racially mixed and, as such, able to deal with race-based conflicts in a quite positive way? As we will strive to demonstrate, these controversies gained momentum as multiculturalism started to inform identity-oriented social movements, which in recent years excelled in challenging the image of Brazil as a successful case of a melting-pot society by denouncing deep-seated social inequalities grounded in racial lines. We want to investigate whether popular resistance to race-based public policies will propel the rise of a sort of resented form of nationalism in Brazil’s public scene.     

Development of multiplex PCRs for evolutionary and forensic applications of 37 human Y chromosome SNPs

This work describes an efficient and rapid test for typing 37 single nucleotide polymorphisms (SNPs) of the non-recombining region of Y chromosome (NRY) from a minimal amount of DNA using six PCR multiplexes. Markers were drawn following a hierarchical strategy based on the phylogenetic tree of Y chromosome proposed by the Y Chromosome Consortium [The Y Chromosome Consortium, A nomenclature system for the tree of human Y-chromosomal binary haplogroups, Genome Res. 12 (2002) 339-348]. Two multiplexes--arbitrarily named MY1 and MY2--were developed to explore the basal branches of the tree encompassing all the major clades A-R: MY1 for markers M35, M89, M172, M170, M9, M173, M45 and MY2 for markers M52, M216, M174, M181, M201, M91, M96, M214. Four multiplexes able of typing the more superficial branches typical of most frequent European haplogroups E3b, J2, R1 and I, were also developed and named MY-E3b (M78, M107, M224, M165, M148, M81), MY-J2 (M158, M68, M47, M102, M137, M67), MY-R1 (M17, M269, M18, P25, SRY10831.2) and MY-I (M72, M223, M26, M21, M161). SNP genotyping was carried out by hot-start PCR amplification with primers yielding fragments between 63 and 210 nucleotides, followed by minisequencing reaction based on dideoxy single-base extension and capillary electrophoresis of extension products. The sequential application of these multiplexes is a robust and effective resource for typing the most frequent European Y-SNP haplogroups, and appears to be suitable for forensic purposes and evolutionary studies.     

A quantitative differentiation method for plastic bags by infrared spectroscopy, thickness measurement and differential scanning calorimetry for tracing the source of illegal drugs

Fifty shopping bags, commonly encountered in the packaging of drug doses, were characterized by thickness measurements, infrared spectroscopy and differential scanning calorimetry. By these very straightforward and inexpensive techniques, without sample preparation, nearly all the considered samples could be discriminated. Ninety-seven percent of the possible pairs of white, apparently similar dull polymer films were differentiated. The rather large degree of variability existing in grocery bags, even though they are mass produced, was shown, confirming that these items can be useful in tracing the source of illicit drug doses.     

The discrimination potential of diffuse-reflectance ultraviolet-visible-near infrared spectrophotometry for the forensic analysis of paper

The application of diffuse reflectance UV-VIS-NIR spectroscopy is proposed to differentiate 20 office paper samples, which had been deemed similar by a preliminary visual examination under several different lighting sources. The samples were firstly screened on the basis of the qualitative appearance of their spectra. A further discrimination was obtained by taking into account three parameters: the average reflectivity of the paper samples in the range 680-900nm, and the integrated intensity of the absorption peak in the UV range at 272nm and at 360nm. The homogeneity of these parameters on both sides of the paper sheets was assessed, detecting a very uniform distribution of the optical brighteners. A special focus was posed on the determination of the discriminative power, in order to give a quantitative parameter on the proposed procedure, which is important when reporting results to the Court. The remarkable achievement of differentiating all the examined samples was obtained by UV-VIS spectroscopy, a very less expensive technique which is readily available in practically all forensic laboratories.
