On the Structure of the Bose-Einstein Condensate Ground State

We construct a macroscopic wave function that describes the Bose-Einstein condensate and weakly excited states, using the su(1,1) structure of the mean-field hamiltonian, and compare this state with the experimental values of second and third order correlation functions.Comment: 10 pages, 2 figure

China's outward foreign direct investment and domestic investment: An industrial level analysis

In the past decade, China's outward foreign direct investment (FDI) has increased significantly. On the other hand, the Chinese economic growth model is heavily reliant on domestic investment. Our study examines the important issue of how China's domestic investment responds to its FDI outflows. We investigate this issue analyzing, for the first time, China's domestic investment at industrial level. We specifically account for the factor of government support given the significant role played by the state in the Chinese economy. Using industrial level data, we further evaluate whether domestic investment reacts to outward FDI differently between state dominated and non-state dominated industries. Our study adopts an accelerator model where the system-Generalized Method of Moments (GMM) is employed for our estimations. Our empirical results suggest that domestic investment responds positively to outward FDI in China, Furthermore, the FDI outflows influences domestic investment differently depending on the level of government support in the particular industries. Such influence is much stronger in state dominated industries than in the non-state dominated ones

Special Education and Parental Decision-Making Experiences: A Hermeneutic Phenomenological Study

The purpose of this hermeneutic phenomenological study was to investigate the decision-making experiences of parents/guardians relative to an offer of Special Education Services for their child. The participants for this study were 10 parents of children in one suburban county in the northern Virginia region who made decisions regarding acceptance of Special Education Services. The children of participating parents were of varying ages and types of disabilities. The two theories that guided this research and helped explain factors that influenced parents’ special education related decision-making experiences were the grief cycle (Haley, Hammond, Ingalls, & Marin, 2013) and decision theory (Dewey, 1910/1978). The central research question in this study was “How did parents/guardians in one suburban county in the northern Virginia region who received notification of eligibility for Special Education Services determine whether they would or would not use those services for their child?” The sub-questions were as follows: 1) How, if at all, did the perception of special education designations impact the decision of parents/guardians in one suburban county in the northern Virginia region to use Special Education Services for their child? 2) How, if at all, did the quality of parent–school collaboration impact the decision of parents/guardians in one suburban county in the northern Virginia region to use Special Education Services for their child? Data were collected through questionnaires, semi-structured interviews, and parental reflections and were analyzed using coding methodologies common to qualitative analysis. The results of the analysis indicated that parents’ special education related decision-making experiences included four primary categories of factors or themes: (a) awareness, (b) negative perceptions, (c) advantage, and (d) trust

Non-Catholic Students’ Cultural and Religious Experiences Attending Catholic High Schools

ABSTRACT This study focused on the experiences of non-Catholic high school students attending two Catholic schools supported by government funding in Ghana. Due to financial constraints, the Catholic Church appealed to the Ghana government for financial support. Once approved, the government became part of the administration of these schools. I explored the meaning non-Catholic students ascribed to their experiences participating in the religious program with the goal of documenting the potential adverse effects of school policies. I adopted a phenomenological qualitative approach for my study. Interviews, observations, and documents constituted the sources of data collection. The data analysis revealed non-Catholic students experienced distress due to several factors. They knew little of the robust religious program of Catholic schools prior to their admission. The schools required all students to participate in Catholic worship. Non-Catholic students felt uncomfortable immersing themselves in a faith they did not profess. Participants described the liturgy as unintelligible because of its symbolism. To adapt, non-Catholic students practiced their faith in secret to maintain their religious identities. Despite the challenges, participants were impressed with the schools’ serene climate and exceptional discipline, which promoted learning. They acknowledged positive relationships between students, teachers, and the administrators with few exceptions. Also, understanding participants’ perspective might initiate a change of the worship policy and give students more freedom to practice their faith and ease the tension between the parties. The schools might need to revise the entrance procedures to ensure applicants know what to expect of them as students attending a Catholic school

Using handheld pocket computers in a wireless telemedicine system

Objectives: To see if senior emergency nurse practitioners can provide support to inexperienced ones in a Minor Injuries Unit by using a wireless LAN system of telemedicine transmitting images to a PDA when they were on duty. In addition, whether such a system could be sufficiently accurate to make clinical diagnoses with a high level of diagnostic confidence. This would permit an overall lower grade of nurse to be employed to manage most of the cases as they arrive with a proportionate lowering of costs. Methods: The wireless LAN equipment could roam in the Minor Injuries Unit and the experienced emergency Nurse practitioners could be at home, shopping or even at a considerable distance from the centre. Thirty pictorial images of patients who had been sent to the Review Clinic were transmitted to a PDA various distances of one to sixteen miles from the centre. Two senior emergency nurse practitioners viewed the images and opined on the diagnosis, their degree of confidence in the diagnosis and their opinion of the quality of the image. Results: the images of patients were sharp, clear, and of diagnostic quality. The image quality was only uncertain, as was the level of confidence of the diagnosis if the patient was very dark skinned. Conclusions: The wireless LAN system works with a remote PDA in this clinical situation. However there are question marks over the availability of enough experienced emergency nurse practitioners to staff a service that provides senior cover for longer parts of the day and at weekends

Coherent pairing states for the Hubbard model

We consider the Hubbard model and its extensions on bipartite lattices. We define a dynamical group based on the $\eta$-pairing operators introduced by C.N.Yang, and define coherent pairing states, which are combinations of eigenfunctions of $\eta$-operators. These states permit exact calculations of numerous physical properties of the system, including energy, various fluctuations and correlation functions, including pairing ODLRO to all orders. This approach is complementary to BCS, in that these are superconducting coherent states associated with the exact model, although they are not eigenstates of the Hamiltonian.Comment: 5 pages, RevTe

Is all Mental Harm Equal? The Importance of Discussing Civilian War Trauma from a Socio-Economic Legal Framework's Perspective

Copyright © Solon Solomon and Ya’akov Bayer, 2023. In recent years, international law scholars have discussed how civilian mental harm in warfare should also form part of the jus in bello proportionality principle and be balanced to the anticipated military advantage. Yet, these scholars have not proceeded one step further to examine whether socio-economic parameters shaping the individual’s personality, such as education, family ties or the level of income, should be also taken into account as varying variables in this balancing task. This is particularly important given that the particular parameters are tied to the socio-economics rights discourse and the relevant minimal living standards notion developed there. Based on a study we conducted, the article explores whether civilian mental harm should be affected by socio-economic parameters and what this means for the wider role socio-economic rights can play in armed conflicts as well as for the reading of jus in bello along Marxist terms

Thermalization of Squeezed States

Starting with a thermal squeezed state defined as a conventional thermal state based on an appropriate hamiltonian, we show how an important physical property, the signal-to-noise ratio, is degraded, and propose a simple model of thermalization (Kraus thermalization).Comment: 7 pages, 1 table, 1 figure.
