Controlling international joint ventures: An investigation of australian parent partners

International joint ventures (IJVs) are an important modern organisational form, with their complexity presenting significant management and control issues. Our research uses a cross-sectional survey of Australian parent partners of IJVs to provide insights into the characteristics of Australian companies and their IJVs, performance outcomes and choices of parent partners management control systems (MCS) design in terms of operational areas they seek to control (focus), the extent to which they exercise control (extent) and the mechanisms of control used (formal and informal). Australian parent partners of IJVs generally are, partnering in countries close to Australia in the Asia-Pacific, in activities similar to those they undertake in Australia, contributing a significant amount of resources, but overall have only limited IJV experience. Australian parent partners focus on a limited set of controls, often with tighter formalised control structures. Finally, overall they are satisfied with the performance of their IJVs, with higher satisfaction for organisational learning and product/customer dimensions than financial performance

Evidence for orbital motion of CW Leonis from ground-based astrometry

© 2017 The Authors.Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations indicate that CW Leo, the closest carbon-rich asymptotic giant branch star to Sun, might have a low-mass stellar companion. We present archival ground-based astrometric measurements of CW Leo obtained within the context of the Torino Parallax Program and with > 6 yr (1995-2001) of time baseline. The residuals to a single-star solution show significant curvature, and they are strongly correlatedwith thewell-known I-band photometric variations due to stellar pulsations. We describe successfully the astrometry of CW Leo with a variability-induced motion (VIM) + acceleration model. We obtain proper motion and parallax of the centre-of-mass of the binary, the former in fair agreement with recent estimates, the latter at the near end of the range of inferred distances based on indirect methods. The VIM + acceleration model results allow us to derive a companion mass in agreement with that inferred by ALMA, they point towards a somewhat longer period than implied by ALMA, but are not compatible with much longer period estimates. These data will constitute a fundamental contribution towards the full understanding of the orbital architecture of the system when combined with Gaia astrometry, providing an ~25 yr time baseline.Peer reviewe

Exoplanet atmospheres with GIANO II. Detection of molecular absorption in the dayside spectrum of HD 102195b

The study of exoplanetary atmospheres is key to understand the differences between their physical, chemical and dynamical processes. Up to now, the bulk of atmospheric characterization analysis has been conducted on transiting planets. On some sufficiently bright targets, high-resolution spectroscopy (HRS) has also been successfully tested for non-transiting planets. We study the dayside of the non-transiting planet HD 102195b using the GIANO spectrograph mounted at TNG, demonstrating the feasibility of atmospheric characterization measurements and molecular detection for non-transiting planets with the HRS technique using 4-m class telescopes. The Doppler-shifted planetary signal changes on the order of many km/s during the observations, in contrast with the telluric absorption which is stationary in wavelength, allowing us to remove the contamination from telluric lines while preserving the features of the planetary spectrum. The emission signal from HD 102195b's atmosphere is then extracted by cross-correlating the residual spectra with atmospheric models. We detect molecular absorption from water vapor at 4.4$\sigma$ level. We also find convincing evidence for the presence of methane, which is detected at the 4.1$\sigma$ level. The two molecules are detected with a combined significance of 5.3$\sigma$, at a semi-amplitude of the planet radial velocity $K_P=128\pm 6$ km/s. We estimate a planet true mass of $M_P=0.46\pm 0.03~M_J$ and orbital inclination between 72.5 and 84.79$^{\circ}$ (1$\sigma$). Our analysis indicates a non-inverted atmosphere for HD 102195b, as expected given the relatively low temperature of the planet, inefficient to keep TiO/VO in gas phase. Moreover, a comparison with theoretical expectations and chemical model predictions corroborates our methane detection and suggests that the detected $CH_4$ and $H_2O$ signatures could be consistent with a low C/O ratio.Comment: 12 pages, 12 figures, accepted for publication in A&

Emphasis on accounting controls: asset specificity and the use of accounting and non-accounting information within IT outsourcing engagements

This study observes the nature of asset specificity in different Information Technology (IT) outsourcing typologies, and investigates the relevance of accounting and non-accounting numbers in relation to these outsourcing typologies, with consideration to the findings of literatures concerning Transaction Cost Economics Theory and Social Capital Theory. It represents a response to the lack of research on relationships of IT outsourcing engagements. A case study research method is used to analyse the effect of asset specificity on the nature of relationship, and the use of accounting and non-accounting information in supporting the decision making processes of the Outsourcing Service Provider. Contrary to the findings of many researchers, the outsourcing-service provider adopted an integrative approach to its relationships as opposed to a distributive approach even in engagements that were highly asset specific, and short-term in duration. Additionally, the nature of asset specificity for IT outsourcing engagements is not static, but dynamic and in continual flux. Overall, this study suggests that large IT outsourcing-service providers value non-accounting factors in decision-making processes, in addition to accounting information, thus reflecting the Integrative Outsourcing Typology. This further validated the fact that factors advocated by Social Capital Theory such as corporate reputation, trust and collaborative interactions are crucial in IT outsourcing relationships

Exoplanet atmospheres with GIANO. I. Water in the transmission spectrum of HD 189733b

High-resolution spectroscopy (R $\ge$ 20,000) at near-infrared wavelengths can be used to investigate the composition, structure, and circulation patterns of exoplanet atmospheres. However, up to now it has been the exclusive dominion of the biggest telescope facilities on the ground, due to the large amount of photons necessary to measure a signal in high-dispersion spectra. Here we show that spectrographs with a novel design - in particular a large spectral range - can open exoplanet characterisation to smaller telescope facilities too. We aim to demonstrate the concept on a series of spectra of the exoplanet HD 189733 b taken at the Telescopio Nazionale Galileo with the near-infrared spectrograph GIANO during two transits of the planet. In contrast to absorption in the Earth's atmosphere (telluric absorption), the planet transmission spectrum shifts in radial velocity during transit due to the changing orbital motion of the planet. This allows us to remove the telluric spectrum while preserving the signal of the exoplanet. The latter is then extracted by cross-correlating the residual spectra with template models of the planet atmosphere computed through line-by-line radiative transfer calculations, and containing molecular absorption lines from water and methane. By combining the signal of many thousands of planet molecular lines, we confirm the presence of water vapour in the atmosphere of HD 189733 b at the 5.5-$\sigma$ level. This signal was measured only in the first of the two observing nights. By injecting and retrieving artificial signals, we show that the non-detection on the second night is likely due to an inferior quality of the data. The measured strength of the planet transmission spectrum is fully consistent with past CRIRES observations at the VLT, excluding a strong variability in the depth of molecular absorption lines.Comment: 10 pages, 8 figures.

Evaluating ASM Materials Camp New England

Worcester Polytechnic Institute has partnered with the Materials Information Society to create ASM Materials Camp New England, an outreach program intended to interest high school students in STEM fields. To improve the efficacy of this program, information from participant surveys, personal observations, and interviews with organizers was summarized and analyzed. Recommendations identifying potential improvements for the program and the evaluation process were generated. These suggestions may be utilized in future camps to interest a greater number of students in STEM
