Knowledge sharing and subsidiary R&D mandate development: A matter of dual embeddedness
2014
Sharing knowledge across borders has proven to be especially relevant to multinational corporations (MNCs). Foreign subsidiaries have become active players in these knowledge flows. However, the network effects of interacting with multiple agents on the evolution of the R&D role played by subsidiaries are still undeveloped. The present study focuses on changes in subsidiary capabilities and on the dynamic mechanisms by which their R&D role might evolve, especially, as a consequence of their interaction with a variety of knowledge networks. We examine this issue by conducting four longitudinal case studies of subsidiaries operating in Spain. Using an inductive approach to theory building, we…
The internalisation of foreign distribution and production activities
2001
Abstract This paper, using a logit model applied to a sample of 323 Spanish companies with international activities, analyses the key factors in the creation of sales and production subsidiaries. A high degree of fit between the results and the established hypotheses can be observed. Many interesting findings related to the main streams of entry mode research (Transaction Cost Theory and the Uppsala Model) have been supported. The intangibility and tacit nature of the products/processes involved in the foreign venture have been directly associated to wholly owned sales and production subsidiaries. Moreover, modes of entry used by Spanish firms are adapted as an incremental, experiential lea…
When are international managers a cost effective solution? The rationale of transaction cost economics applied to staffing decisions in MNCs
2005
Abstract A common claim in the literature of expatriation is the one referring to the high costs of expatriation. In this paper, on the basis of transaction cost economics (TCE), we show how limited this approach is. In particular, we consider a set of costs that, although ignored in traditional expatriation literature, must be accounted for when a MNC is deciding on whether to recruit expatriates or local managers in its subsidiaries. These costs include selection, training, and performance evaluation costs. We also formulate a series of hypotheses around the situations in which the total costs of recruiting expatriates are lower than those generated by local managers. We then test these h…
Intermediate units in multinational corporations: A resource dependency view on coordinative versus entrepreneurial roles
2021
Abstract Due to the dispersion of headquarters’ activities across organizational and geographical boundaries, intermediate units (IUs) are emerging as a key actor of international business. IUs are intermediate structural layers between headquarters (HQ) and local subsidiaries with specific HQ responsibilities. Our study relies on original data of 67 IUs and, taking on a Resource Dependence approach, explores empirically the two HQ roles attributed to IUs: coordinative versus entrepreneurial. According to our results, the main differences between both roles relate to external network embeddedness, internal network position and autonomy. We argue that these differences arise from the dominan…
The new Athena alpha particle X-ray spectrometer for the Mars Exploration Rovers
2003
[1] The new alpha particle X-ray spectrometer (APXS) is part of the Athena payload of the two Mars Exploration Rovers (MER). The APXS sensor head is attached to the turret of the instrument deployment device (IDD) of the rover. The APXS is a very light-weight instrument for determining the major and minor elemental composition of Martian soils, rocks, and other geological materials at the MER landing sites. The sensor head has simply to be docked by the IDD on the surface of the selected sample. X-ray radiation, excited by alpha particles and X rays of the radioactive sources, is recorded by a high-resolution X-ray detector. The X-ray spectra show elements starting from sodium up to yttrium…
On simfitting MER Mössbauer data to characterize Martian hematite
2010
Mossbauer spectra of Eagle Crater outcrop rocks in Meridiani Planum were acquired by the Mars Exploration Rover (MER) Opportunity. Sixty spectra, containing ~20 to 60% hematite by area, were simultultaneously fit (simfit) in a self-consistent manner to a single chi-squared minimum, where relations among parameters from different spectra were defined for both sol (Martian day) and acquisition temperature (200–280 K). Different spectral models were compared, hematite being modeled optimally with two sextets. Sextet S1 (~35% of total sextet area) has narrower linewidths, a larger magnetic hyperfine field, and a quadrupole shift that changes smoothly from positive to negative values as the temp…
Athena Mars rover science investigation
2003
[1] Each Mars Exploration Rover carries an integrated suite of scientific instruments and tools called the Athena science payload. The primary objective of the Athena science investigation is to explore two sites on the Martian surface where water may once have been present, and to assess past environmental conditions at those sites and their suitability for life. The remote sensing portion of the payload uses a mast called the Pancam Mast Assembly (PMA) that provides pointing for two instruments: the Panoramic Camera (Pancam), and the Miniature Thermal Emission Spectrometer (Mini-TES). Pancam provides high-resolution, color, stereo imaging, while Mini-TES provides spectral cubes at mid-inf…
Robust and Efficient IMEX Schemes for Option Pricing under Jump-Diffusion Models
2013
We propose families of IMEX time discretization schemes for the partial integro-differential equation derived for the pricing of options under a jump diffusion process. The schemes include the families of IMEX-midpoint, IMEXCNAB and IMEX-BDF2 schemes. Each family is defined by a convex parameter c ∈ [0, 1], which divides the zeroth-order term due to the jumps between the implicit and explicit part in the time discretization. These IMEX schemes lead to tridiagonal systems, which can be solved extremely efficiently. The schemes are studied through Fourier stability analysis and numerical experiments. It is found that, under suitable assumptions and time step restrictions, the IMEX-midpoint fa…
Gli aspetti fiscali delle attività di rigenerazione e riuso di beni a fini di interesse generale.
2017
E’ possibile attribuire un riconoscimento, una legittimazione ed una regolamentazione giuridica all'opera prestata dai privati nell'attività di rigenerazione e riuso di beni di interesse comune? La leva fiscale può essere considerata come strumento per favorire lo sviluppo di queste attività? Alla prima domanda possiamo rispondere che il concetto, oggi in evoluzione, di sussidiarietà orizzontale, sembra essere lo strumento più idoneo per inquadrare giuridicamente le azioni di privati cittadini che volontariamente decidono di prendersi cura di beni comuni ai più diversi livelli (beni immobili o mobili concernenti il patrimonio artistico/culturale o, più in generale, fruibili da una collettiv…
“Mel” ~ “fel”: il dolce e l’amaro della doppiezza in alcuni testi poetici mediolatini dei secoli XI-XIII
2021
In questa nota viene proposta una rassegna di testi poetici mediolatini dei secoli XI-XIII – in particolare le commedie elegiache e i componimenti misogini – nei quali compare l’opposizione metaforica, ossimorica e paronomastica "mel" ~ "fel", volta a stigmatizzare la doppiezza che sovente caratterizza i comportamenti degli uomini e, soprattutto, delle donne. This note proposes a review of Middle-Latin poetic texts of the 11th-13th centuries – in particular the elegiac comedies and the misogynistic compositions – in which the metaphorical, oxymorical and paronomastic opposition "mel" ~ "fel" appears, aimed at stigmatizing the duplicity that often characterizes the behavior of men and, above…
