Purpose: Minimally invasive adrenalectomy is the standard of care for primary lateralized aldosteronism. Controversy related to clinical cure rates, prediction scores, and the role of adrenal vein sampling (AVS) for lateralization abound. Methods: Retrospective analysis of 53 consecutive adrenalectomy patients from 2013–2021, consisting of demographics, descriptive epidemiology, statistical comparison of pre- and post-adrenalectomy blood pressure, anti-hypertensive medications, plasma aldosterone and renin activity values, comparison of predictive scores, concordance of AVS for lateralization with cross-sectional imaging. Results: Forty-seven (89%) had a beneficial outcomes—19 (36%) achieving both biochemical/clinical cure, 28 (53%) clinically improved. The Utsumi score was superior to the aldosteronoma resolution score (ARS) in discriminating likelihood of cure, particularly in patients <40 years old. Sixteen patients (30%) with pathologic proven hyperplasia, had lower rates of cure or improvement. Forty-seven patients (89%) underwent both cross-sectional imaging and AVS; of those, 45/47 (96%) had concordant lateralization. In a broader cohort of 119 patients at our institution AVS, concordance rates decreased (63%). Conclusion: Adrenalectomy for primary aldosteronism leads to clinical improvement in most, but a far lower fraction achieve full clinical cure of hypertension. Proper expectations of adrenalectomy, must incorporate the Utility of predictive scores, and the significance of any form of unilateral hyperplasia. AVS is broadly nonconcordant with cross-sectional imaging in 33%, but in carefully selected patients can be highly concordant raising the possibility of selective bypassing of AVS in in those <40 years old

Testing invariance is important in cross-cultural studies because a lack of invariance may bias empirical results and lead to improper theoretical inferences. This study introduces and validates a scale for measuring entrepreneurial investment climate, consisting of four factors: Societal stability, Labor and Regulations, Quality of Infrastructure, and Ease of Finance. The instrument was developed using World Bank Group data from 51,169 firms and 72 institutional profiles to determine investment climate. Confirmatory factor analyses reveal the validity of the scale and its robustness across country types and time. The study's implications for practice and future research are discussed.

<P>The LUX-ZEPLIN (LZ) experiment will search for dark matter particle interactions with a detector containing a total of 10 tonnes of liquid xenon within a double -vessel cryostat. The large mass and proximity of the cryostat to the active detector volume demand the use of material with extremely low intrinsic radioactivity. We report on the radioassay campaign conducted to identify suitable metals, the determination of factors limiting radiopure production, and the selection of titanium for construction of the LZ cryostat and other detector components. This titanium has been measured with activities of U-238(e) < 1.6 mBq/kg, U-238(I) < 0.09 mBq/kg, Th-232(e) = 0.28 +/- 0.03 mBq/kg, Th-232(I) = 0.25 +/- 0.02 mBq/kg, K-40 <0.54 mBq/kg, and (60) Co <0.02 mBq/kg (68% CL). Such low intrinsic activities, which are some of the lowest ever reported for titanium, enable its use for future dark matter and other rare event searches. Monte Carlo simulations have been performed to assess the expected background contribution from the LZ cryostat with this radioactivity. In 1,000 days of WIMP search exposure of a 5.6-tonne fiducial mass, the cryostat will contribute only a mean background of 0.160 +/- 0.001(stat) +/- 0.030(sys) counts. (C) 2017 Elsevier B.V.

Abuse of Process and Regulation in Commercial Arbitration – A Chinese Perspective
Arthur X. Dong 한국중재학회 2015 중재연구 Vol.25 No.3
This paper discusses the problem of extraordinary delay in the commercial arbitration process, increased arbitration fees, and denial of the benefits of arbitration to other parties due to the abuse of procedural rights by relevant parties in commercial arbitration process. This paper proposes measures to reduce abuse of process in commercial arbitration, such as statutory modification, judicial supervision, amendment of arbitration rules and the intervention of disciplinary bodies.

Common belief in border regions holds that Mexican cross-border shoppers play a larger role in the regional economic base than they do and that NAFTA will provide a bigger stimulus to the regional economy than it is likely. In the first case, price elasticities are implicitly under - estimated as highly inelastic and in the latter case, overestimated as highly elastic. This paper provides empirical evidence on the effects of distance and real exchange rates as price proxies on both field survey and population-imputed estimates of cross-border shopping. After estimating both distance-based and real exchange rate-based estimates of price elasticities of Mexican shopper demand for U. S. border-region goods, implications are obtained concerning the relative importance for U.S. border-region economies of more distant Mexican markets, and the likely impacts of NAFTA.
Articles : Optimal Monetary and Exchange-Rate Policy with Wage Indexation
( Arthur Benavie ),( Richard Froyen ) 세종대학교 경제통합연구소 1992 Journal of Economic Integration Vol.7 No.2
This paper investigates the setting and coordination of monetary policy and foreign exchange market intervention. This is done within a framework that invokes neither purchasing power parity nor uncovered interest parity and which allows for wage indexation. Optimal policies are designed in the presence of domestic IS, LM and productivity shocks, as well as international asset demand shocks and foreign income, price and interest rate shocks. One feature of these policies is that for the monetary policy parameter a Poole (1970)-type ranking emerges, with a fixed interest rate optimal for all financial shocks and a vertical LM curve optimal for domestic IS and foreign income shocks. Also of interest is the fact that for both these sets of shocks a fixed exchange rate is part of the optimal policy. Only for foreign price shocks is an exchange rate adjustment part of the optimal response.
