North-South customs unions and international capital mobility

The primary distinction in a North-South trade accord is likely to be that the Southern nation experiences more capital scarcity than its Northern trade partner. So the trade accord's impact on the Southern trading partner's ability to attract capital may have welfare implications for both nations. The authors extend the traditional analysis of customs unions to allow for international capital movements. Their results indicate that trade accords may affect the ability of Southern nations to attract capital and may divert capital between Southern nations. Moreover, the welfare implications of North-South trade accords may differ from those that predict the North American Free Trade Agreement's (NAFTA) minor third-country effects, holding factor endowments constant. The key implications of North-South trade accords such as NAFTA are generally perceived to involve their impact on investment flows. The authors try to understand the channels through which trade accords can affect North-South investment flows. A potential link between trade accords and investment flows may be how the accords affect the ability of the Southern partner government to make commitments about the treatment of foreign investment. They show that these accords can affect both the magnitude and pattern of inward foreign investment and production, implying the possibility that both trade and financial diversioncan stem from a bilateral regional trade accord. Novel effects that emerge under sovereign risk must be addressed when assessing the welfare implications of trade accords. The greatest gains from integration are still achieved when integration takes place between the countries with the greatest potential gains from trade. But the authors make a distinction: these gains now include both current trade and inter-temporal trade through foreign investment.Environmental Economics&Policies,Economic Theory&Research,Payment Systems&Infrastructure,International Terrorism&Counterterrorism,Fiscal&Monetary Policy,Trade and Services,Economic Theory&Research,Environmental Economics&Policies,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Trade and Regional Integration

Quantum phase transitions of atom-molecule Bose mixtures in a double-well potential

The ground state and spectral properties of Bose gases in double-well potentials are studied in two different scenarios: i) an interacting atomic Bose gas, and ii) a mixture of an atomic gas interacting with diatomic molecules. A ground state second-order quantum phase transition (QPT) is observed in both scenarios. For large attractive values of the atom-atom interaction, the ground-state is degenerate. For repulsive and small attractive interaction, the ground-state is not degenerate and is well approximated by a boson coherent state. Both systems depict an excited state quantum phase transition (ESQPT). For the mixed atom-molecule system the critical point of the ESQPT displays a discontinuity in the first derivative of the density of states.Comment: 25 pages, 18 figures.

Excited-state quantum phase transitions in a two-fluid Lipkin model

Background: Composed systems have became of great interest in the framework of the ground state quantum phase transitions (QPTs) and many of their properties have been studied in detail. However, in these systems the study of the so called excited-state quantum phase transitions (ESQPTs) have not received so much attention. Purpose: A quantum analysis of the ESQPTs in the two-fluid Lipkin model is presented in this work. The study is performed through the Hamiltonian diagonalization for selected values of the control parameters in order to cover the most interesting regions of the system phase diagram. [Method:] A Hamiltonian that resembles the consistent-Q Hamiltonian of the interacting boson model (IBM) is diagonalized for selected values of the parameters and properties such as the density of states, the Peres lattices, the nearest-neighbor spacing distribution, and the participation ratio are analyzed. Results: An overview of the spectrum of the two-fluid Lipkin model for selected positions in the phase diagram has been obtained. The location of the excited-state quantum phase transition can be easily singled out with the Peres lattice, with the nearest-neighbor spacing distribution, with Poincar\'e sections or with the participation ratio. Conclusions: This study completes the analysis of QPTs for the two-fluid Lipkin model, extending the previous study to excited states. The ESQPT signatures in composed systems behave in the same way as in single ones, although the evidences of their presence can be sometimes blurred. The Peres lattice turns out to be a convenient tool to look into the position of the ESQPT and to define the concept of phase in the excited states realm

Recent Private Capital Inflows to Developing Countries: Is the Debt Crisis History?

This empirical study finds that while debt reduction and policy reforms in debtor countries have been important determinants of renewed access to international capital markets, changes in international interest rates have been the dominant factor. We calculate the effects of changes in international interest rates for a 'typical' debtor country. We conclude that increases in interest rates associated with business cycle upturn in industrial countries could depress the secondary market prices of existing debt to levels inconsistent with continued capital inflows.

Neonaticide in the Courtroom – Room for Improvement? Conclusions Drawn from Austria and Finland's Register Review

This study analyses the psychological, clinical and criminal characteristics of neonaticide focusing on court verdicts with the aim of formulating recommendations for judicial guidelines. This study was register based, comprising all known neonaticides in Austria and Finland between 1995 and 2005. The cases (n = 28) were obtained by screening death certificates from coroner departments and analysing them alongside all further reports available. Five out of 21 convicted offenders were imprisoned with an average sentence of 1.65 years. A mental disorder, at the time of the offence, was diagnosed in half of the offenders (9/18) who underwent forensic examination. Of the total offenders, 14 were deemed responsible for the crime, one was deemed to have had diminished responsibility and three were considered not responsible for the crime. The main motive, determined by court evaluation, was an ?unwanted child?, followed by ?no motive?, ?fear of abandonment or a negative response from others? and 'mental overload'. The rate of repeated neonaticide was 13 per cent. Considering the rate of mental illness within the neonaticide offenders, we would recommend a treatment detention order instead of imprisonment or non-prosecution, as well as state-of-the-art guidelines for the court. ?Analyses the psychological, clinical and criminal characteristics of neonaticide focusing on court verdicts? Key Practitioner Messages Autopsies should be conducted for all suspected neonaticides. Forensic examinations should be performed by experts with knowledge and experience of neonaticide. There should be standardised forensic examinations using structured psychiatric and psychological methods by two independent experts. Neonaticide cases should be tried in specialised courts. A psychiatric treatment order should be made for all neonaticide offenders as a preventive measure to reduce reoffending and address the high psychological burden.Peer reviewe

Genome-wide association study of regional brain volume suggests involvement of known psychiatry candidate genes, identified new candidates for psychiatric disorders and points to potential modes of their action

Though most psychiatric disorders are highly heritable, it has been hard to identify genetic risk factors involved, which are most likely of small individual effect size. A possible way to aid identification of risk genes is the use of intermediate phenotypes. These are supposed to be closer to the biological substrate(s) of the disorder than psychiatric diagnoses, and therefore less genetically complex. Intermediate phenotypes can be defined e. g. at the level of brain function and of regional brain structure. Both are highly heritable, and regional brain structure is linked to brain function. Within the Brain Imaging Genetics (BIG) study at the Radboud University Nijmegen (Medical Centre) we performed a genome-wide association study (GWAS) in 1000 of the currently 1400 healthy study participants. For all BIG participants, structural MRI brain images were available. Gray and white matter volumes were determined by brain segmentation using SPM software. FSL-FIRST was used to assess volumes of specific brain structures. Genotyping was performed on Affymetrix 6.0 arrays. Results implicate known candidates from earlier GWAS and candidate gene studies in mental disorders in the regulation of regional brain structure. E. g. polymorphisms in CDH13, featuring among the top-findings of GWAS in disorders including ADHD, addiction and schizophrenia, were found associated with amygdala volume. The ADHD candidate gene SNAP25 was found associated with total brain volume. In conclusion, the use of intermediate phenotypes based on (subcortical) brain volumes may shed more light on pathways from genes to diseases, but can also be expected to facilitate gene identification in psychiatric disorders

Participant music listening behaviours in interactive multimedia music instruction

While emerging technologies such as interactive multimedia are increasingly being employed in computerised music instruction, understanding of participant music listening behaviours in interactive multimedia music instruction is currently very limited. With the aim of elucidating music listening behaviour, the central concern of this work is to identify and explain participant interactions with the audio components of interactive multimedia music instruction. The investigation employs a novel documentation procedure, which extends the application of digital audio recording technology, to provide a finely calibrated analysis of the audio activity of a sample of 20 undergraduate music education majors during individual sessions with two commercially-available interactive multimedia music instruction programs. Graphically-based Sound Activity Profiles, which the researcher developed specifically for the current investigation, characterise and summarise participant interactions with audio components, while an analysis of questionnaire responses and follow-up interview transcripts provides supplementary information that further explains participants' music listening behaviours. The results of the investigation show that music listening behaviours during the study sessions were highly variable. While extensive participant interaction with music examples occasionally reflected attentive music listening behaviours, many study sessions were characterised by brief, fragmentary music excerpts and lengthy periods of silence. Participants spent as little as five percent of their session time listening to music and as much as 88 percent of the session time in silence. A substantial number of the study cohort frequently interrupted the music examples they had activated. Participants' perceptions of the extent of their interaction with music examples were frequently inaccurate, as subjects often substantially overestimated the amount of session time they had spent listening to music. The study findings suggest that many interactive multimedia music instruction participants would benefit from interventions that elicit more extensive and prolonged interaction with music examples. Accordingly, recommendations include a call for research to develop and test software designs that incorporate automated monitoring of session audio activity so that dynamic on-screen information about music listening behaviour can be provided to interactive multimedia music instruction participants. Such information may encourage participants to modify inappropriate music listening behaviours
