Interaction ramps in a trapped Bose condensate

Non-adiabatic interaction ramps are considered for trapped Bose-Einstein condensates. The deviation from adiabaticity is characterized through the heating or residual energy produced during the ramp. We find that the dependence of the heat on the ramp time is very sensitive to the ramp protocol. We explain features of this dependence through a single-parameter effective description based on the dynamics of the condensate size.Comment: 4 pages, 3 figure

Interdisciplinary Education In Dental Hygiene: A Pilot Project

This study describes a five-hour interdisciplinary experience involving sophomore dental hygiene students, dental hygiene faculty and medical technology faculty. This experience met the objectives of interdisciplinary teaching while reinforcing and expanding on a present topic in a four-year dental hygiene curriculum. The results of this experience are documented by pre- and post-testing and student evaluations. Statistical analysis of the test results along with student commentaries support interdisciplinary education as a viable and positive teaching approach. Student ability to correctly answer topic-related cognitive questions increased significantly while their understanding of the medical technology profession and its relationship to dental hygiene also developed. The experience was included within the framework of the pre-clinical dental hygiene course which kept the implementation efficient and perhaps contributed to its success. This pilot project was a positive step toward cθntinued interdisciplinary experiences between the dental hygiene and medical technology programs and created enthusiasm for expanding the experiences in the future to include the other health programs

Dipolar Bose-Einstein condensate of Stationary-Light Dark-state Polaritons

We put forward and discuss in detail a scheme to achieve Bose-Einstein condensation of stationary-light dark-state polaritons with dipolar interaction. To this end we have introduced a diamond-like coupling scheme in a vapor of Rydberg atoms under the frozen gas approximation. To determine the system's dynamics we employ normal modes and identify the dark-state polariton corresponding to one of the modes. We show that in contrast to atomic dipolar ultra-cold vapors dark-state polariton Bose-Einstein condensates proposed here can be stable for a negative dipolar interaction constant.Comment: 5 pages, 1 figur

Use of Interdisciplinary Education to Foster Familiarization among Health Professionals

This paper describes a pilot interdisciplinary experience between the dental hygiene and medical technology programs at Marquette University. It was designed, in part, to familiarize dental hygiene students with the medical technology profession. Comments solicited from students on the final evaluation form indicated that this pilot project was highly successful and met the objectives. Affective, multiple-choice questions on pretests and posttests showed a positive change in attitude, but this change was not statistically significant. Possible reasons for this are discussed. Benefits of this pilot project were an improved understanding of medical technology on the part of the dental hygiene students, enhanced interdepartmental communication, and plans to develop a reciprocal interdisciplinary experience for the medical technology students. It is hoped that this pilot project will serve as a stimulus for similar experiences among other health science programs

A History of the Oldham, South Dakota Socialist Hall from 1913 to 1970

There may be many reasons for the appearance of the Socialist Hall in Oldham, South Dakota. Certainly a primary factor for its construction was the controversial Socialist party that formed a local branch in the Oldham area in 1912. It may be of interest to note that the town of Oldham had an opera house operating prior to the Socialist Hal1 and after the new hal1 was constructed, both continued to provide the community with a wide variety of entertainment and community activities. Unfortunately, the lack of information and the limited time and space does not allow the first opera house to be included in this study. It should also be pointed out that the size of the community, its geographic location, and its accessibility to a major railway were also important factors relating to the need to maintain the Socialist Hall in Oldham, South Dakota. The hall is currently located on the grounds of Prairie Village, South Dakota and provides South Dakota State University\u27s Summer Repertory Theatre a place to perform summer plays. As a previous member of this company with a personal interest in local history, the writer felt motivated to undertake a detailed investigation of the history of the Oldham, South Dakota Socialist Hall. To develop this history, answers to the following questions were sought: (1) What factors were responsible for the construction of the Socialist Hall in Oldham, South Dakota? (a) What role did the local Socialist party play? (b) What other factors may have been influential to the construction of the Hall? (2) How was the physical design of the building related to the Hall\u27s adaptability to various activities? (a) How was the exterior constructed? (b) What were the physical properties of the interior that helped it to be utilized as a multipurpose Hal)? (c) How was the Socialist Hall managed? (3) What professional dramatic touring companies performed .in the Hall? (4) What professional variety touring companies performed at the Hall? (5) How was the Socialist Hall used to support amateur drama in the community? (6) What major rhetorical activities took place in the Hall? (a) What professional lecture agencies were active in the Hall? (b) How did the community utilize the Socialist Hall for political and community meeting? (7) What other community functions were held in the Socialist Hal)? (8) How well received were the aforementioned activities? (9) What led to the demise of the Socialist Hall? It is hoped that this study will inspire others to research similar areas so that a more complete understanding of the functional importance of the local opera houses and community halls can be provided. A study of this nature may also provide a better understanding of theatre and rhetorical activities in rural America

The US current account deficit : how did it come about and what are the policy implications

One of the most remarkable characteristics of the world economy today is the enormous, ever worsening US balance of payments current account deficit, which reached a record level of 5.7 p.c. of GDP in 2004. This has given rise to concerns in academic and political circles regarding the sustainability of the current situation and the potential dangers for the global economy of a sudden, disorderly adjustment. The size of the US current account deficit is not only unprecedented in American post-war history, but it also seems to be exceptional from an international perspective. Moreover, the US deficit contrasts with a surplus in virtually every other region and the problem has consequently taken on a global dimension. The increase in the US current account deficit recorded in the nineties reflects an internal American shortfall in savings. Whereas the private savings-investment equilibrium was restored in 2002 and 2003, the same period saw a huge deficit in the public sector budget. The start of the new millennium brought notable changes in the way the US current account deficit was financed since investments by Asian public authorities in American government debt instruments largely took over the position previously occupied by European private foreign direct investments and investments in equities. It is sometimes put forward that the US, unlike other countries facing similar circumstances, is safeguarded from an attack on its currency because of its prominent role in the international financial system. According to an influential school of thought in economic literature, the current international system can even be seen as a “revived” Bretton Woods system. Indeed, a number of East-Asian countries, including China, use a fixed or quasi-fixed exchange rate against the dollar, which brings to mind an informal dollar standard. Although this set of circumstances has undoubtedly offered various regions in the world a number of mutual benefits during recent years, these exchange rate relations may nevertheless have caused some distortions in US spending, whereas Asian countries have to deal with a growing exchange rate risk on their official reserves. Different scenarios are conceivable to deal with the global imbalances. The results of model simulations show the huge effort required to significantly reduce the US current account deficit which highlights the scale of the problem, emphasising the need for simultaneous economic policy measures in the different economies involved. The concern over global imbalances and the development of exchange rates also feature prominently on the agenda of international forums such as the G7 or G20 meetings. In the statements issued at those meetings, the need for a common approach to tackle the global imbalances is given priority and the belief that excessive exchange rate volatility is not desirable is underlined.current account imbalances, United States current account, financial flows into the United States, international monetary system

Focus accent, word length and position as cues to L1 and L2 word recognition

The present study examines native and nonnative perceptual processing of semantic information conveyed by prosodic prominence. Five groups of German learners of English each listened to one of 5 experimental conditions. Three conditions differed in place of focus accent in the sentence and two conditions were with spliced stimuli. The experiment condition was presented first in the learners’ L1 (German) and then in a similar set in the L2 (English). The effect of the accent condition and of the length and position of the target in the sentence was evaluated in a probe recognition task. In both the L1 and L2 tasks there was no significant effect in any of the five focus conditions. Target position and target word length had an effect in the L1 task. Word length did not affect accuracy rates in the L2 task. For probe recognition in the L2, word length and the position of the target interacted with the focus condition

Less Than 2 °C Warming by 2100 Unlikely.

The recently published Intergovernmental Panel on Climate Change (IPCC) projections to 2100 give likely ranges of global temperature increase in four scenarios for population, economic growth and carbon use1. However these projections are not based on a fully statistical approach. Here we use a country-specific version of Kaya's identity to develop a statistically-based probabilistic forecast of CO2 emissions and temperature change to 2100. Using data for 1960-2010, including the UN's probabilistic population projections for all countries2-4, we develop a joint Bayesian hierarchical model for GDP per capita and carbon intensity. We find that the 90% interval for cumulative CO2 emissions includes the IPCC's two middle scenarios but not the extreme ones. The likely range of global temperature increase is 2.0-4.9°C, with median 3.2°C and a 5% (1%) chance that it will be less than 2°C (1.5°C). Population growth is not a major contributing factor. Our model is not a "business as usual" scenario, but rather is based on data which already show the effect of emission mitigation policies. Achieving the goal of less than 1.5°C warming will require carbon intensity to decline much faster than in the recent past

Pathways to Disability Income among Persons with Severe, Persistent Psychiatric Disorders

[Excerpt] Harsh skepticism pervades current public debate about who deserves public support and on what basis, particularly regarding the claims of individuals with disabling illness and injury. Heretofore, these claims were accepted, even reservedly, and the needs of such individuals were considered to be legitimate even when they were monitored closely. The Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) programs and their recipients have been among the most visible and vulnerable targets of increased scrutiny and shrinking public beneficence. In 1997, congressional legislation redefined SSI eligibility for children, sparked largely by concerns that children have been deployed to engage in a type of public begging by acting crazy in order to secure benefits for their families. Maladaptive behaviors was removed from the mental disorder listings, and the Social Security Administration (SSA) estimates that 135,000 children will lose their benefits after review. In March 1996, Congress eliminated SSI, SSDI, Medicare, and Medicaid benefits for persons whose drug addiction or alcoholism is a prominent cause of disability, and as a result 141,000 recipients have been terminated. The SSA also was ordered to begin another sweeping review of all recipients of disability income. SSA officials reportedly expect this process to produce a termination rate of 14 percent, resulting in an estimated 196,000 additional individuals who would cease to receive SSI and SSDI
