Does Information Technology Investment Influences Firm’s Market Value? The Case of Non-Publicly Traded Healthcare Firms

Managers make informed information technology investment decisions when they are able to quantify how IT contributes to firm performance. While financial accounting measures inform IT’s influence on retrospective firm performance, senior managers expect evidence of how IT influences prospective measures such as the firm’s market value. We examine the efficacy of IT’s influence on firm value combined with measures of financial performance for non-publicly traded (NPT) hospitals that lack conventional market-based measures. We gathered actual sale transactions for NPT hospitals in the United States to derive the q ratio, a measure of market value. Our findings indicate that the influence of IT investment on the firm is more pronounced and statistically significant on firm value than exclusively on the accounting performance measures. Specifically, we find that the impact of IT investment is not significant on return on assets (ROA) and operating income for the same set of hospitals. This research note contributes to research and practice by demonstrating that the overall impact of IT is better understood when accounting measures are complemented with the firm’s market value. Such market valuation is also critical in merger and acquisition decisions, an activity that is likely to accelerate in the healthcare industry. Our findings provide hospitals, as well as other NPT firms, with insights into the impact of IT investment and a pragmatic approach to demonstrating IT’s contribution to firm value

Seasonal variation of tropospheric methyl bromide concentrations: Constraints on anthropogenic input

Although removal of tropospheric methyl bromide (CH3Br) is dominated by the reaction with the seasonally varying hydroxyl (HO) radical concentration, the anticipated corresponding seasonal dependence of CH3Br, as found for other gases with major HO sinks, has been sought previously without success [WMO, 1995]. Our observations of northern hemispheric boundary layer CH3Br concentrations do reveal substantial seasonal changes. The high latitude CH3Br North/South interhemispheric concentration ratio (IHR) varies from a maximum of 1.35±0.04 (1σ) in March-April to 1.10±0.04 in September, with an equal area and seasonally (EAS) weighted average IHR of 1.21±0.03. These observations suggest northern hemispheric emissions are about 15 kilotons/year less than when an IHR of 1.3 is considered [WMO, 1995]. The observed seasonality also partially explains the differences in the IHR reported by several research groups [WMO, 1995] and places needed constraints on the magnitude and seasonality of sources and sinks of CH3Br

Hubungan antara amalan pengurusan rantaian bekalan hijau (GSCM) dan prestasi rantaian bekalan di sektor pembuatan, Batu Pahat, Johor

Pola pertumbuhan ekonomi telah meningkatkan tahap penggunaan tenaga dan bahan-bahan dan memberi kesan kepada kemampanan alam sekitar. Kemakmuran ekonomi bagi penduduk bandar yang lebih besar, lebih banyak membawa kepada pembaziran pengeluaran. Hal ini berlaku kerana penghasilan sisa dipengaruhi oleh proses perindustrian. Sisa dari sektor pembuatan boleh mendatangkan ancaman terhadap bekalan air, kesihatan awam dan alam sekitar melalui penyebaran bakteria lalu mengakibatkan pencemaran sumber air. Air yang tercemar mungkin mengandungi kepekatan bahan-bahan pencemaran yang tinggi yang dihasilkan oleh kilang-kilang dan akan datang kembali kepada pengguna melalui kitaran air sebagai sumber utama untuk kegunaan harian. Oleh itu, pengguna terdedah kepada pelbagai penyakit dan sekali gus boleh menjejaskan tahap kesihatan mereka (Khairul, Rahman & Ho, 2011). Isu alam persekitaran merupakan isu yang kian mencabar kepada organisasi perniagaan pada masa kini. Pemanasan global, pengurangan kualiti udara dan pencemaran air merupakan beberapa contoh kesan alam sekitar yang boleh dikaitkan dengan aktiviti yang selaras dengan rantaian bekalan organisasi. Pada 9 April 2009, Perdana Menteri telah mengumumkan pembentukan Kementerian Tenaga, Teknologi Hijau dan Air (KeTTHA) bagi menggantikan Kementerian Tenaga, Air dan Komunikasi. Teknologi Hijau merujuk kepada pembangunan dan aplikasi produk, peralatan serta sistem untuk memelihara alam sekitar dan alam semulajadi dan meminimumkan atau mengurangkan kesan negatif daripada aktiviti manusia

Nonmethane hydrocarbon and halocarbon distributions during Atlantic Stratocumulus Transition Experiment/Marine Aerosol and Gas Exchange, June 1992

Aircraft measurements of selected nonmethane hydrocarbon and halocarbon species were made in the lower troposphere of the NE Atlantic near the Azores, Portugal, during June 1992 as part of the Atlantic Stratocumulus Transition Experiment/Marine Aerosol and Gas Exchange. In this paper, the impact of continental outflow from both Europe and North America on the study region were assessed. Four main air mass types were characterized from trajectories and trace gas concentrations: clean marine from the Atlantic, and continental air from the Iberian Peninsula, the British Isles and Northern Europe, and North America. Each classification exhibited trace gas concentrations that had been modified en route by photochemical processes and mixing. Comparison with the clean marine boundary layer (MBL) shows that the boundary layer of the predominantly continental air masses were enhanced in hydrocarbons and halocarbons by factors of approximately 2 for ethane, 5 for propane, 2-6 for ethyne and benzene, and 2-3 for C2Cl4. The same air masses also exhibited large ozone enhancements, with 2 to 3 times higher mixing ratios in the continental boundary layer air compared to the clean MBL. This indicates a primarily anthropogenic photochemical source for a significant fraction of the lower tropospheric ozone in this region. Methyl bromide exhibited on average 10-20% higher concentrations in the boundary layer affected by continental outflow than in the clean MBL, and was seen to be enhanced in individual plumes of air of continental origin. This is consistent with significant anthropogenic sources for methyl bromide. In addition, median MBL concentrations of ethene and methyl iodide showed enhancements of approximately a factor of 2 above free tropospheric values, suggesting primarily coastal/oceanic sources for these species.
