Pengaruh Karakteristik Demografis dan Gaya Hidup terhadap Niat Beli di Starbucks

Gaya hidup konsumen merupakan sa- saran penting yang harus dipertimbangkan oleh produsen. Hal ini dikarenakan gaya hidup mencakup pola hidup kon- sumen yang melibatkan pemilihan produk dan gaya konsumsi sehari-hari konsumen tersebut. Selain gaya hidup, karakteristik demografik juga akan mempengaruhi niat beli. Dalam penelitian ini akan diteliti pengaruh dari gaya hidup dan karakteristik demografik terhadap niat beli konsumen Starbucks. Penelitian dilakukan pada 100 orang responden. Data yang diperoleh diolah menggunakan me- tode regresi linier berganda. Hasil yang diperoleh menun- jukkan bahwa baik gaya hidup maupun karakteristik de- mografik berpengaruh terhadap niat beli konsumen

In situ XRF and gamma ray spectrometer for Mars sample return mission

A combined in situ X-ray fluorescence (XRF) and passive gamma ray spectrometer instrument is proposed for the chemical elemental analysis of various Martian surfaces and samples. The combined instrument can be carried on board a rover. The passive gamma ray or the neutron excited gamma ray system would be used to determine the elemental composition of the Martian surface while the rover is in motion. The XRF system would be used to perform analysis either on the Martian surface or on collected samples when the rover is stationary. The latter function is important both in cataloging the collected samples and in the selection of samples to be returned to earth. For both systems, data accumulation time would be on the order of 30 minutes. No sample preparation would be necessary

Common misdiagnosis of a common neurological disorder : how are we misdiagnosing essential tremor?

Background: As a common neurological disorder, the diagnosis of essential tremor (ET) is considered routine. Despite this, previous work suggests that misdiagnoses may be common. Among other things, these misdiagnoses can lead to treatment errors. Objectives: To estimate how often other tremor disorders are misdiagnosed as ET and to identify factors that increase the odds of misdiagnosing ET and to precisely quantify the extent to which they do so. Design: Seventy-one consecutive patients underwent an evaluation at the Neurological Institute of New York, New York, between January 1, 2000, and December 31, 2005; these patients had a preevaluation diagnosis of ET. The criteria for ET were adapted from the consensus statement of the Movement Disorder Society. Results: Twenty-six patients (37%) were misdiagnosed as having ET ("false ET"). Their true diagnoses were Parkinson disease (11 patients [15%]), dystonia (6 patients [8%]), Parkinson disease with ET (5 patients [7%]), and other disorders (4 patients [6%]). Factors associated with misdiagnosed ET included unilateral arm tremor (odds ratio, 10.5; 95% confidence interval, 1.2-95.4; P=.02), spooning of the hands and other dystonic postures (odds ratio, 16.3; 95% confidence interval, 4.0-66.4; P<.001), and other unusual features (isolated thumb tremor, isolated leg tremor, and nonrhythmic tremor) (odds ratio, 49.4; 95% confidence interval, 2.7-895.0; P<.001). Conclusions: About 1 in 3 patients with tremor was misdiagnosed as having ET, with the most frequent false diagnoses being Parkinson disease and dystonia. Several factors that increased the odds of misdiagnosing ET were identified. These factors could be incorporated into improved diagnostic algorithms

Radiation-associated angiosarcoma after autologous breast reconstruction: report of two cases in a plastic surgery unit

Radiation-associated breast angiosarcoma is a rare diagnosis but is commonly reported. Angiosarcoma occurring in non-breast tissue in breasts that have been reconstructed with autologous tissue following mastectomy is extremely rare. In our unit, we have managed two patients with angiosarcoma arising in non-breast tissue autologous reconstructions. Our report emphasises that any tissue treated with radiotherapy—that is, the residual mastectomy skin flaps or non-breast tissue autologous reconstructions—are at a risk of secondary angiosarcoma. We also discuss recommended surgical management, surveillance and genetic testing. Level of Evidence is V, risk study

Financial rogue waves

The financial rogue waves are reported analytically in the nonlinear option pricing model due to Ivancevic, which is nonlinear wave alternative of the Black-Scholes model. These solutions may be used to describe the possible physical mechanisms for rogue wave phenomenon in financial markets and related fields.Comment: 4 papges, 2 figures, Final version accepted in Commun.
