Effects of the higher partial waves and relativistic terms on the accuracy of the calculation of the hypertriton electroproduction

We have investigated the accuracies of calculations made by omitting the higher partial waves of nuclear wave functions and the elementary relativistic terms in the hypertriton electroproduction. We found that an accurate calculation would still be obtained if we used at least three lowest partial waves with isospin T = 0. Furthermore, we found that the omission of the relativistic terms in the elementary process amplitude could lead to a large deviation from the full calculation. We also present the cpu-times required to calculate the cross sections. For future consideration the use of these lowest partial waves is suggested, since the calculated cross section deviates only about 0.17 nb/sr (approximately 4%), at most, from the full calculation, whereas the cpu-time is reduced by a factor of 60. Comparison of our result with the available experimental data supports these findings.Comment: 12 pages, 4 figures, submitted to Nucl. Phys.

Wal-Mart Imports From China, Exports Ohio Jobs

[Excerpt] This report tells the stories of four Ohio companies that sell to Wal-Mart. The loss of jobs at the Huffy Corp., Rubbermaid, Mr. Coffee and Thomson factories in Ohio demonstrates how Wal-Mart pressures suppliers to send Ohio jobs overseas. These jobs exported by Wal-Mart suppliers represent just a handful of the hundreds of thousands of good jobs Ohio has lost in the new Wal-Mart economy. Other such Wal-Mart suppliers as Hasbro, Ohio Art, Texas Instruments Inc., Hoover, World Kitchen Inc. and Philips also have closed plants in Ohio

Entanglement behavior of quantum states of fermionic system in accelerated frame

In this article we investigate the entanglement behavior of quantum states of fermionic system in accelerated frame. It was known that unlike scalar case the entanglement of fermionic maximally entangled states survives even in the infinite acceleration limit. Also for the fermionic system it was discussed that one may consider the approach beyond single mode approximation. However due to the peculiar property of fermionic system there has been different opinions about correct physical structure of fermionic system. Recently Montero and Mart\'{i}n-Mart\'{i}nez suggested an approach beyond single mode approximation. Using the structure proposed by Montero and Mart\'{i}n-Mart\'{i}nez we investigate the entanglement behavior of quantum states of fermionic system in accelerated frame. We find that the approach by Montero and Mart\'{i}n-Mart\'{i}nez seems to work appropriately. Also we may obtain the proper entanglement behavior of quantum states in fermionic system in accelerated frame(our result may correct the previous results published in Phys.Rev.A 83 052306)

Walmart Sweatshop Litigation Dismissed

Document from the 9th Circuit Court in California dismissing charges brought up by employees of Wal-Mart\u27s foreign suppliers. The case was dismissed on the grounds that the plaintiffs did not state a claim against Wal-Mart, only its suppliers, which Wal-Mart had no legal duty to monitor

Impact of monotherapy on HIV-1 reservoir, immune activation, and co-infection with Epstein-Barr virus

Abstract Objectives Although monotherapy (mART) effectiveness in maintaining viral suppression and CD4 cell count has been extensively examined in HIV-1-infected patients, its impact on HIV-1 reservoir, immune activation, microbial translocation and co-infection with Epstein-Barr Virus (EBV) is unclear. Methods This retrospective study involved 32 patients who switched to mART; patients were studied at baseline, 48 and 96 weeks after mART initiation. Thirty-two patients who continued combined antiretroviral therapy (cART) over the same period of time were included in the study. Markers of HIV-1 reservoir (HIV-1 DNA and intracellular HIV-1 RNA) were quantified by real-time PCR. Markers of T-(CD3(+)CD8(+)CD38(+)) and B-(CD19(+)CD80/86(+) and CD19(+)CD10-CD21(low)CD27(+)) cell activation were evaluated by flow cytometry. Plasma levels of microbial translocation markers were quantified by real-time PCR (16S ribosomal DNA and mitochondrial [mt] DNA) or by ELISA (LPS and sCD14). EBV was typed and quantified by multiplex real-time PCR. Results At baseline, no differences were found between mART and cART groups. Three (10%) mART-treated patients had a virological failure vs none in the cART group. Levels of HIV-1 DNA, intracellular HIV-1 RNA and EBV-DNA remained stable in the mART group, while decreased significantly in the cART group. Percentages of T-and B-activated cells significantly increased in the mART-treated patients, while remained at low levels in the cART-treated ones (p = 0.014 and p<0.001, respectively). Notably, levels of mtDNA remained stable in the cART group, but significantly rose in the mART one (p<0.001). Conclusions Long-term mART is associated with higher levels of T-and B-cell activation and, conversely to cART, does not reduce the size of HIV-1 reservoir and EBV co-infection

The Effects of Wal-Mart on Local Labor Markets

We estimate the effects of Wal-Mart stores on county-level retail employment and earnings, accounting for endogeneity of the location and timing of Wal-Mart openings that most likely biases the evidence against finding adverse effects of Wal-Mart stores. We address the endogeneity problem using a natural instrumental variables approach that arises from the geographic and time pattern of the opening of Wal-Mart stores, which slowly spread out from the first stores in Arkansas. The employment results indicate that a Wal-Mart store opening reduces county-level retail employment by about 150 workers, implying that each Wal-Mart worker replaces approximately 1.4 retail workers. This represents a 2.7 percent reduction in average retail employment. The payroll results indicate that Wal-Mart store openings lead to declines in county-level retail earnings of about $1.2 million, or 1.3 percent. Of course, these effects occurred against a backdrop of rising retail employment, and only imply lower retail employment growth than would have occurred absent the effects of Wal-Mart.Wal-Mart; Employment

Visitors&apos; experience in a modern art museum: a structural equation model

This study aims to provide a better understanding on the museum experience by studying visitors’ motivation, satisfaction and likelihood to return to the Museum for Modern and Contemporary Art (MART) of Rovereto (Italy). The empirical data were obtained from a survey undertaken from September to November 2009. A theoretical model to analyze the attractiveness factors of the museum based on two exogenous variables (push and pull motivation) and two endogenous variables (satisfaction and loyalty) is used and a structural equation model is estimated as a confirmatory tool of the hypothetical model. The findings reveal that tourists visiting the MART are mainly motivated by push factors, as relaxation, looking for a new experience and learn new things. Loyalty also positively influences the probability to return to the MART and recommend to friends and family. However, visit the city or the region of Trentino has no impact on satisfaction and loyalty to the MART. Besides, loyalty to MART does not imply the probability to recommend a visit to Rovereto

The Effects of Wal-Mart on Local Labor Markets

We estimate the effects of Wal-Mart stores on county-level retail employment and earnings, accounting for endogeneity of the location and timing of Wal-Mart openings that most likely biases the evidence against finding adverse effects of Wal-Mart stores. We address the endogeneity problem using a natural instrumental variables approach that arises from the geographic and time pattern of the opening of Wal-Mart stores, which slowly spread out from the first stores in Arkansas. The employment results indicate that a Wal-Mart store opening reduces county-level retail employment by about 150 workers, implying that each Wal-Mart worker replaces approximately 1.4 retail workers. This represents a 2.7 percent reduction in average retail employment. The payroll results indicate that Wal-Mart store openings lead to declines in county-level retail earnings of about $1.4 million, or 1.5 percent. Of course, these effects occurred against a backdrop of rising retail employment, and only imply lower retail employment growth than would have occurred absent the effects of Wal-Mart.

The Impact of Wal-Mart on Local Fiscal Health: Evidence from a Panel of Ohio Counties

This research analyzes selected fiscal impacts of Wal-Mart in Ohio from 1985 through 2003. Using a panel of counties, and accounting for spatial autocorrelation in an instrumental variable model I estimate impact of Wal-Mart and Super-Centers on selected revenues and transfer payments. On revenues I find that the presence of a Wal-Mart increases local commercial property tax assessments, resulting in collection increases of between $350,000 to roughly$1.3 million. Wal-Mart also is associated with higher levels of local labor force participation. On expenditures I also find that the presence of a Wal-Mart dramatically increases the per capita EITC claims in a county (between 18 and 43 percent), while the dollar value of these claims experiences mixed impacts between Wal-Mart and a Supercenter. Similarly, the impact of Wal-Mart on Foodstamps expenditures is mixed, but small in any case. There are no in-county impacts of Wal-Mart on expenditures on Temporary Assistance to Needy Families and its predecessor Aid to Families with Dependent Children. However, Medicaid expenditures experience growth which may amount to roughly 16 additional cases per county attributable to a single Wal- Mart. The per worker costs of Medicaid estimated in this study is consistent with reported levels in a number of states, and study estimates by Dube and Jacobs [2004], Carlson [2005] and Hicks [2005a]. The magnitude and statistical certainty of these findings, accompanied by a review of previous research suggests that local fiscal intervention, either through incentives or the much touted “Wal-Mart Tax” is unwarranted.

What Do Quarterly Workforce Dynamics Tell Us About Wal-Mart? Evidence from New Stores in Pennsylvania

In this paper I seek to better inform debate regarding Wal-Mart’s local impact on wages, and employment dynamics by combining data on Wal-Mart stores with the recently release Quarterly Workforce Indicators provided by the US Census. Use a panel of Pennsylvania counties, who saw entrance of a Wal-Mart in 2002, I find a new store has no effect on existing employee wages in the retail sector. However, new retail sector hires experience a roughly $0.50 an hour increase in total compensation in the quarter Wal-Mart enters. The entrance of a Wal- Mart draws employees from existing businesses, reducing job creation while increasing net job flows. Wal-Mart also has a longer term effect on net employment of a little more than 50 jobs in a total year. This employment finding is quite similar to findings in Hicks and Wilburn [2001] and Basker [2005]. Perhaps most importantly, Wal-Mart entrance is associated with a dramatic decline in retail sector job turnovers (over 40 percent). This result challenges much of the received wisdom of Wal-Mart’s role in the retail sector. The policy implications of these findings echo those of Ken Stone, who cautions against activist policy in support, or against Wal-Mart at the local level. Disclosure: The author of this study owns no stock in Wal-Mart or any related firm (other than that held by the mutual fund companies Vanguard and TIAA-CREF). I have performed no paid consulting services from any retail firm, its developers, local governments or related entities since 2002 (though I continue to field frequent questions on my earlier research). I have received no honoraria related to Wal-Mart research (other than travel costs paid by the Federal Reserve Bank of Richmond in 2001). In short, except for roughly$1,500 purchases of diapers annual since 1999 I have no financial relationship with Wal-Mart or any affiliate that I am aware of.Wal-Mart, Pennsylvania, Quarterly Workforce Indicators
