Poverty and Temporary Employment in Italy

AbstractThis paper explores the relationship between temporary employment and poverty in Italy by using 2016–2019 longitudinal EU-SILC data. We model both poverty and labour market outcomes and account for possible endogeneity of temporary employment in the poverty equation. We find that temporary employment reduces the risk of poverty whether compared with inactivity and unemployment. Temporary workers are more likely to stay in poverty with respect to their permanent counterpart. The different effect of permanent/temporary employment on the risk of poverty is more pronounced for householders than for partners, thereby stressing the leading role of the former in income formation. There is evidence of feedback effects from past poverty to current temporary employment. We also find significant genuine state dependence in both the processes of poverty and temporary employment. For the latter, we note the prevalence of a trapping effect into unstable jobs relationships, especially for householders. Finally, we stress the relatively weak role of social transfers in integrating labour income from temporary employment and therefore in breaking the detrimental effect of temporary work on poverty.

Probing the nature of the anticharmed-strange pentaquark states: Mass spectra, decays, and magnetic moments

Within the framework of the quark delocalization color screening model, a systematic investigation of the anticharmed-strange pentaquark system is performed using the resonance group method. The currently estimations predict three bound states with estimated masses to be 2886 MeV, 3039 MeV, and 3153 MeV, respectively. Additionally, three resonance states are identified in various scattering phase shifts processes. Among them, two resonance states ΣD¯ and Σ*D¯* with quantum number 12(12−) are detected in channels ND¯s* and ND¯, and ΣD¯* and ΛD¯, with masses and decay widths of (MR=3053–3055 MeV, Ttotal=13.0–13.4 MeV) and (MR=3389–3390 MeV, Ttotal=10.4 MeV), respectively. In the ΛD¯* and ΣD¯* channels, a resonance state with quantum number 12(32−) is discovered, with its mass and decay width being 3250–3252 MeV and 4.4,MeV, respectively. These predicted pentaquark states have c¯snnn quark compositions, allowing them to be recognized as genuine pentaquark states. To validate these predictions, it is expected that upcoming experiments will further explore the predicted resonance and bound states in these possible decay channels.

Heavy exotic hadrons near thresholds: [formula omitted] and its partners

Recent accelerator experiments have reported unexpected states known as exotic hadrons, whose properties cannot be explained by the conventional picture. In 2022, the LHCb collaboration reported the doubly charmed tetraquark Tcc+ which is a genuine exotic states whose minimal quark content is ccūd̄. We consider the Tcc state as a DD∗ hadronic molecule. The one meson exchange potentials are employed as for the hadron interactions, and a bound state properties is investigated. Furthermore, the superflavor symmetry predicts a new pentaquark state D̄Ξcc from Tcc, which is obtained by replacing a D(∗) meson with a Ξcc(∗) baryon. We also study a possible existence of the D̄Ξcc bound state, and its properties.

Big administration reforms against Catholic reformist traditions: fusion of state and church mid-level school administrations in early nineteenth-century Prussian Silesia

ABSTRACT In what are often described as modern Western school systems, the supervision of elementary schools generally shifted from the hands of clerical administrators to genuine state officials during the nineteenth century. The Prussian state, like other predominantly Protestant states, relied on clerical personnel and church supervision structures to establish its school supervision administration. Yet, this was also true for the more Catholic parts of the Prussian monarchy, where integration of church structures into state administration caused friction between state and church authorities. Hence, this contribution focuses on appointments of school inspectors in early nineteenth-century Prussian Silesia, when friction arose between the state and the prince-bishop concerning appointment rights. These frictions are reflected in the process of newly introduced mid-level state school administrations taking over episcopal appointment rights, which has been described as a nationalisation or secularisation of Silesian school administration. The article proposes a more nuanced approach to the restructuring of Silesian school administration, driven by consecutive administration reforms resulting in a fusion of church and state administration, rather than a traditional secularisation narrative. It traces the subtle ties between the Prussian state, episcopal administration, and clerical inspection personnel that led to the gradual assertion of state over ecclesiastical structures.

Quadrature Squeezing Enhances Wigner Negativity in a Mechanical Duffing Oscillator

Generating macroscopic nonclassical quantum states is a long-standing challenge in physics. Anharmonic dynamics is an essential ingredient to generate these states, but for large mechanical systems, the effect of the anharmonicity tends to become negligible compared with the effect of decoherence. As a possible solution to this challenge, we propose using a motional squeezed state as a resource to effectively increase the anharmonicity. We analyze the production of negativity in the Wigner distribution of a quantum anharmonic resonator initially in a squeezed state. We find that initial squeezing increases the rate at which negativity is generated. We also analyze the effect of two common sources of decoherence—namely, energy damping and dephasing—and find that the detrimental effects of energy damping are suppressed by strong squeezing. In the limit of large squeezing, which is needed for state-of-the-art systems, we find good approximations for the Wigner function. Our analysis is significant for current experiments attempting to prepare macroscopic mechanical systems in genuine quantum states. We provide an overview of several experimental platforms featuring nonlinear behaviors and low levels of decoherence. In particular, we discuss the feasibility of our proposal with carbon nanotubes and levitated nanoparticles. Published by the American Physical Society 2024

The persistence of labour market states in Australia

PurposeThe study investigates persistence of individuals' labour market activity with a focus on examining whether and to what extent there is genuine state dependence in six labour market states: not-in-labour-force, unemployment, self-employment, casual employment, fixed term contracts, and ongoing employment, and how the persistence and genuine state dependence of the labour market states change with education levels.Design/methodology/approachA dynamic multinomial logit model that accounts for observed and unobserved individual heterogeneity is estimated, using the first 19 waves of the Household, Income, and Labour Dynamics in Australia Survey.FindingsWhile observed and unobserved individual heterogeneity plays an important role in the persistence of each of the labour market states examined, genuine state dependence is found to be present for all the states. It is also found that the persistence and genuine state dependence of unemployment is larger among those with a low education attainment than among those with higher education.Practical implicationsThe existence of genuine state dependence of labour market states calls for early interventions to prevent people from losing jobs.Originality/valueEarlier studies often focus on persistence of a particular labour market state such as unemployment, while this study examines the persistence simultaneously of six labour market states.

The maximal violation of the Svetlichny inequality for “X” states and the extended GHZ states

For a quantum system, violation of a Svetlichny inequality indicates the existence of genuine nonlocality. Through the same mathematical analysis approach, we derive the analytical expressions of the maximal violation of the Svetlichny inequality for certain three-qubit pure states and mixed “X” states. These pure states represented in the five-parameter form belong to extended GHZ states. It is convenient to use the obtained expression to distinguish the genuine nonlocal states in these states. We also obtain the analytical expression of the maximal violation of Svetlichny inequality for a subclass of four-qubit “X” states. We show the application potentiality of these expressions by designing two schemes where quantum resources are converted from less qubits “X” states to more qubits “X” states.

Experimental realization of a three-photon asymmetric maximally entangled state and its application to quantum state transfer.

Quantum entanglement is crucial for quantum information processing, prominently used in quantum communication, computation, and metrology. Recent studies have shifted toward high-dimensional entangled states, offering greater information capacity and enabling more complex applications. Here, we experimentally prepared a three-photon asymmetric maximally entangled state, comprising two two-dimensional photons and one four-dimensional photon. Using this state, we conducted a proof-of-principle experiment, successfully transferring a four-dimensional quantum state from two photons to another photon with fidelities ranging from 0.78 to 0.86. These results exceed theoretical limits, demonstrating genuine four-dimensional quantum state transfer. The asymmetric entangled state demonstrated here holds promise for future quantum networks as a quantum interface facilitating information transfer across quantum systems with different dimensions.

Optimizing fictitious states for Bell inequality violation in bipartite qubit systems with applications to the tt¯ system

There is a significant interest in testing quantum entanglement and Bell inequality violation in high-energy experiments. Since the analyses in high-energy experiments are performed with events statistically averaged over phase space, the states used to determine observables depend on the choice of coordinates through an event-dependent basis and are thus not genuine quantum states, but rather “fictitious states.” We find that the basis which diagonalizes the spin-spin correlations is optimal for constructing fictitious states to test the violation of Bell’s inequality. This result is applied directly to the bipartite qubit system of a top and antitop produced at a hadron collider. We show that the beam axis is the optimal basis choice near the tt¯ threshold production for measuring Bell inequality violation, while at high transverse momentum the basis that aligns along the momentum direction of the top is optimal.

Exotic Qqq¯q¯ states in the chiral quark model

In the framework of the chiral quark model, we investigate the Qqq¯q¯ (Q=c, b and q=u, d) tetraquark system with two structures: Qq¯−qq¯ and Qq−q¯q¯. The bound-state calculation shows that for the single channel, there is no evidence for any bound state below the minimum threshold in both cqq¯q¯ and bqq¯q¯ systems. However, after coupling all channels of two structures, we obtain a bound state below the minimum threshold in the cqq¯q¯ system with the energy of 1998 MeV, and the quantum number is IJP=120+. Meanwhile, in the bqq¯q¯ system, two bound states with energies of 5414 MeV and 5456 MeV are obtained, and the quantum numbers are IJP=120+ and IJP=121+, respectively. Besides, we also employ the real-scaling method to search for resonance states in the cqq¯q¯ and bqq¯q¯ systems. Unfortunately, no genuine resonance states were obtained in both systems. We suggest future experiments to search for these three possible bound states. Published by the American Physical Society 2024

Parenthood put to the test by average prematurity

Any premature birth can be traumatic, and a risk factor for the parenting process and the quality of parent-baby interactions. Average prematurity is no exception. It can undermine essential parenting functions, such as availability and sensitivity to the child, and generate interactive dysfunctions within parent-baby dyads. In some cases, it can lead to genuine psychopathological states.

Hierarchy of multipartite correlations based on concentratable entanglement

Multipartite entanglement is one of the hallmarks of quantum mechanics and is central to quantum information processing. In this work we show that concentratable entanglement (CE), an operationally motivated entanglement measure, induces a hierarchy upon pure states from which different entanglement structures can be experimentally certified. In particular, we find that nearly all genuine multipartite entangled states can be verified through the CE. Interestingly, GHZ states prove to be far from maximally entangled according to this measure. Instead we find the exact maximal value and corresponding states for up to 18 qubits and show that these correspond to extremal quantum error correcting codes. The latter allows us to unravel a deep connection between CE and coding theory. Finally, our results also offer an alternative proof, on up to 31 qubits, that absolutely maximally entangled states do not exist. Published by the American Physical Society 2024

The ‘Real’ Transgender Citizen: Diagnostic Practices of Gender Dysphoria and Citizenship Eligibility in Pakistan

ABSTRACT Emergent meanings of gender dysphoria in medical consultations between transgender people and psychiatrists in Pakistan attempt to answer the question- who is genuinely transgender? The use of biomedical models to investigate the ‘realness’ of trans experience has orchestrated complexities of care as psychiatric evidence of gender dysphoria becomes the gateway to citizenship. Psychiatrists become accessories of state bureaucracy as assessors of legitimate citizenship claims in relation to the Transgender Persons (Protection of Rights) Act 2018. I follow the developing meanings of gender dysphoria as it becomes socially imbricated with Sunni Muslim medical ethics regarding the ‘natural’ body. Even as gender variant citizens discover their selves as political participants, their bodies need to correspond with biopsychological truths of citizenship in an infrastructure of suspicion. How does the sociality of the medical encounter make space for proving or denying gender dysphoria as a genuine psychic state? This paper looks at the varied ways in which doctor-patient interactions become a place of evidence production to satisfy state legislative demands of citizen psychology. Using an interdisciplinary approach that draws on legal literature and medical anthropology, I explore diagnostic practices and expectations of gender dysphoria to explicate the meaning of transgender health within psychiatric care.

Poverty, work intensity, and disability: evidence from European countries.

We use 2015-2018 European Union Statistics on Income and Living Conditions longitudinal data for four European countries (the UK, Germany, France, and Italy) and a dynamic trivariate panel data model to analyze the complex relationship between poverty, work intensity, and disability. We find evidence of genuine state dependence in the three processes and feedback effects from past poverty to work intensity in all countries and from past poverty to disability in the UK, Germany, and Italy. Disability is detrimental to poverty, despite the mitigating role played by disability cash benefits. The magnitude of this effect seems to be associated with the average expenditure on social protection benefits and its distribution across functions. We stress the importance of accounting for the extra costs of disability and the key role work intensity plays in the disability-poverty connection. Finally, adopting a joint estimation strategy appears crucial to consistently estimating the relationship between the three processes.

In-work poverty in Western Europe. A longitudinal perspective

ABSTRACT This study investigates levels and determinants of in-work poverty (IWP) in Western Europe using EU-SILC longitudinal data 2004–2019. We compared IWP risk and their dynamics across fourteen countries by examining individual labor market positions, household total labor supplies, and employment patterns. We further explored the social class gradient in exposure to IWP, as well as drivers and patterns of longitudinal accumulation of poverty. Relying on a single (standard) earner is often not enough to keep families out of poverty, confirming the importance of dual-earner household arrangements, even if they entail non-standard employment conditions for one partner. This holds particularly true for countries with high levels of IWP and for less privileged social and occupational groups across all contexts. Analyzing IWP inertia, we examined the interplay between genuine state dependence (GSD) and unobserved heterogeneity in the accumulation of economic disadvantage over time. Previous experiences with IWP can lead to future IWP for some, yet this causal effect appears rather small. Our findings have clear implications for the social stratification of risk and policies designed to combat poverty accumulation.

Međunarodni standardi ljudskih prava i prinudna psihijatrijska zaštita - razvoj i pogled iz Srbije

Unlike the interpretation of the UN Committee on the Rights of Persons with Disabilities (hereinafter: CRPD Committee), which prohibits any deprivation of liberty on the basis of mental disability, the laws of member states continue to allow and implement involuntary psychiatric measures. The recent objection by the CRPD Committee to the adoption of a legally binding document at the Council of Europe level, which aims to regulate the protection of the human rights and dignity of individuals with mental disorders, could potentially have negative consequences. At this point, a legally binding agreement is more significant than a complete prohibition on placement in psychiatric institutions without consent or the exclusion of substitute decision-makers from providing consent for treatment. This is supported by Serbian legislation, which has certain deficiencies in the procedures for the placement and treatment of individuals with mental disorders. Involuntary measures should be applied only in exceptional cases, and a legally binding document that reflects genuine state consensus could be beneficial for creating laws and ensuring protection for those subjected to involuntary psychiatric measures.

Brazilian forest restoration: Success or better than nothing?

The Brazilian scientific community and non-governmental groups have been working to establish forest restoration programs, compensating for deforestation and mitigating losses from biodiversity and ecosystem services. In contrast, the previous Brazilian government moved in an opposite direction, revoking legal acts and providing scope for the rural producers to sustain non-compliance activities according to the legal regulations. Among rural producers, there is a recognized conflict between agricultural production and forest restoration programs, which results in a chaotic condition where the implementation of the environmental laws is impaired. In this context, restoration projects are often practiced without effective integrated territorial planning. This scenario challenges the success of large-scale restoration programs. The Brazilian government needs to effectively adopt sound guidelines already suggested to promote a genuine state of governance, fostering restoration programs, and moving the country's development towards an ecologically planned environment.

Paving the way out of destitution: Does resilience capacity matter? Panel data evidence from rural Ethiopia

This paper examines the effect of shocks on destitution, vulnerability to destitution, and its dynamics and how resilience mediates the relationship between shocks and destitution based on three waves of the Ethiopian Socioeconomic Survey and applying econometric models. Alkire and Foster's intensity approach and the Resilience Index Measurement and Analysis approach were employed to compute the destitution and resilience indices. The findings show that destitution and households vulnerable to becoming destitute have increased over time due to concurrent and recurrent exposure to shocks. The result also reveals that the distribution of the destitute exhibits a distinct spatial heterogeneity among regions more vulnerable, tending to have many destitute. We also find a genuine state dependence on destitution. Therefore, a destitute in the preceding year is more likely to be destitute in the subsequent years. The econometric results confirm that enhancing the rural non-farm economy and investing in irrigation, market, and road infrastructure have a role in reducing destitution. However, shocks, land fragmentation, loans, female headship, and dependency ratio put households at the most significant risk of destitution. Results also show that commercialization and literacy reduce destitution. Building resilience capacity also emerged as the vital mediator in escaping destitution in the presence of shocks. The spatial disparity highlights the need for strategies designed using a territorial approach. Critical for policy uptake, the findings suggest putting in place coherent preemptive and redemptive policies to have a far-reaching impact on reducing destitution and vulnerability.

State dependence in immunization and the role of discouragement

We investigate whether having a child immunized at a prior schedule genuinely increases the likelihood of vaccinating the child at the subsequent schedule. We use longitudinal data from the Growing Up in New Zealand study and apply a dynamic random-effects model that also controls for the initial immunization status. Prior to any covariate-adjusted estimations, our data shows that almost 96% of the children immunized at the previous schedule are also immunized at the subsequent schedule. In comparison, only 29% of children who were not immunized at the prior schedule receive immunization at the next milestone, thereby indicating an unadjusted state dependence in immunization of 67 percentage points (p.p.). Upon controlling for relevant covariates and unobserved heterogeneities, the genuine state dependence in immunization is, on average, estimated to be 20 p.p. Importantly, the magnitude of the state dependence is greater for Māori (by 5 p.p.) and also greater for mothers that report being discouraged from having their child immunized during the antenatal period (by 10 p.p.).
