Labor costs and productivity trends in selected Brazilian manufacturing industries: An internat. comparison
The analysis focuses on the iron and steel industry, the motor vehicle and the non-electrical machinery industry as well as the manufacture of wearing apparel and footwear. The iron and steel industry and the motor vehicle industry were chosen, because they are characterized by low to middle skill level, capital-intensive production processes (Wolter 1974, 66-67; Walter 1982, 1; Humphrey 1982, 101; Kageyama, 1984, 25). The non-electrical machinery industry was selected, because it depends traditionally more on skilled labor, and less on physical capital (Dick 1981, 30; UNIDO 1984, 5 and 60). Finally the wearing apparel and the footwear industries represent the case of labor-intensive production processes that draw mainly on unskilled labor (Pearson 1983, 65; ILO 1979, 30). Throughout the analysis all manufacturing is used as a common benchmark. Reference is made to major competing newly industrialized countries, i.e., South Korea, Taiwan, Hong Kong, and Mexico, as well as to industrialized countries such as the United States, Spain, Japan, and the Federal Republic of Germany. Section II will clarify the most important conceptual and methodological issues and some shortcomings of previous labor cost analyses, and lay the ground for the empirical investigation pursued in this study. Partial findings of previous studies on Brazilian labor costs will be referred to as complementary information in the empirical part of the study (Section III). In Section IV the major results of the analysis will be summarized.
Selective and unspecific expropriation of foreign direct investments: Empir. evidence and implications for the debt crisis
The persistence of the.international debt crisis has given rise to considerations that foreign direct investment (FDD should play a larger role in the financing of less developed countries (LDCs) in the future. FDIs may provide external financing for developing countries even in times when new lending is restricted due to high credit risks. Flexible payment schedules and the extended property rights may differentiate FDIs from international loans and provide shelter against high country risks. However, FDIs are subject to sovereign risk as well. The option of sovereign states to defer loan repayments as soon as the.costs of contract fulfillment exceed the benefits has its counterpart in expropriations of FDI. The potential of substituting FDI for debt depends on the attitude of the LDCs1 governments towards FDI. A larger role for FDI, especially in times of restricted new lending, will only be possible if the political and economic situation of the borrowing country that induces creditors to expect a higher risk of willful default does not increase the risk of expropriations at the same time.

AI and IP: Theory to Policy and Back Again – Policy and Research Recommendations at the Intersection of Artificial Intelligence and Intellectual Property
The interaction between artificial intelligence and intellectual property rights (IPRs) is one of the key areas of development in intellectual property law. After much, albeit selective, debate, it seems to be gaining increasing practical relevance through intense AI-related market activity, an initial set of case law on the matter, and policy initiatives by international organizations and lawmakers. Against this background, Zurich University’s Center for Intellectual Property and Competition Law is conducting, together with the Swiss Intellectual Property Institute, a research and policy project that explores the future of intellectual property law in an AI context. This paper briefly describes the AI/IP Research Project and presents an initial set of policy recommendations for the development of IP law with a view to AI. The recommendations address topics such as AI inventorship in patent law; AI authorship in copyright law; the need for sui generis rights to protect innovative AI output; rules for the allocation of AI-related IPRs; IP protection carve-outs in order to facilitate AI system development, training, and testing; the use of AI tools by IP offices; and suitable software protection and data usage regimes
Redefining standards—response to: introductions of technological innovations in neurosurgery
<jats:title>Abstract</jats:title><jats:p>This paper presents radon flux profiles from four regions in Schleswig–Holstein (Northern Germany). Three of these regions are located over deep-rooted tectonic faults or salt diapirs and one is in an area without any tectonic or halokinetic activity, but with steep topography. Contrary to recently published studies on spatial patterns of soil radon gas concentration we measured flux of radon from soil into the atmosphere. All radon devices of each profile were deployed simultaneously to avoid inconsistencies due to strong diurnal variations of radon exhalation. To compare data from different seasons, values had to be normalized. Observed radon flux patterns are apparently related to the mineralogical composition of the Quaternary strata (particularly to the abundance of reddish granite and porphyry), and its grain size (with a flux maximum in well-sorted sand/silt). Minimum radon flux occurs above non-permeable, clay-rich soil layers. Small amounts of water content in the pore space increase radon flux, whereas excessive water content lessens it. Peak flux values, however, are observed over a deep-rooted fault system on the eastern side of Lake Plön, i.e., at the boundary of the Eastholstein Platform and the Eastholstein Trough. Furthermore, high radon flux values are observed in two regions associated with salt diapirism and near-surface halokinetic faults. These regions show frequent local radon flux maxima, which indicate that the uppermost strata above salt diapirs are very inhomogeneous. Deep-rooted increased permeability (effective radon flux depth) or just the boundaries between permeable and impermeable strata appear to concentrate radon flux. In summary, our radon flux profiles are in accordance with the published evidence of low radon concentrations in the “normal” soils of Schleswig–Holstein. However, very high values of radon flux are likely to occur at distinct locations near salt diapirism at depth, boundaries between permeable and impermeable strata, and finally at the tectonically active flanks of the North German Basin.</jats:p>
A Novel Technique for Region and Linguistic Specific nTMS-based DTI Fiber Tracking of Language Pathways in Brain Tumor Patients
Navigated transcranial magnetic stimulation (nTMS) has recently been
introduced as a non-invasive tool for functional mapping of cortical language
areas prior to surgery. It correlates well with intraoperative
neurophysiological monitoring (IONM) findings, allowing defining the best
surgical strategy to preserve cortical language areas during surgery for
language-eloquent tumors. Nevertheless, nTMS allows only for cortical mapping
and postoperative language deficits are often caused by injury to subcortical
language pathways. Nowadays, the only way to preoperatively visualize language
subcortical white matter tracts consists in DTI fiber tracking (DTI-FT).
However, standard DTI-FT is based on anatomical landmarks that vary
interindividually and can be obscured by the presence of the tumor itself. It
has been demonstrated that combining nTMS with DTI-FT allows for a more
reliable visualization of the motor pathway in brain tumor patients.
Nevertheless, no description about such a combination has been reported for
the language network. The aim of the present study is to describe and assess
the feasibility and reliability of using cortical seeding areas defined by
error type-specific nTMS language mapping (nTMS-positive spots) to perform
DTI-FT in patients affected by language-eloquent brain tumors. We describe a
novel technique for a nTMS-based DTI-FT to visualize the complex cortico-
subcortical connections of the language network. We analyzed quantitative
findings, such as fractional anisotropy values and ratios, and the number of
visualized connections of nTMS-positive spots with subcortical pathways, and
we compared them with results obtained by using the standard DTI-FT technique.
We also analyzed the functional concordance between connected cortical nTMS-
positive spots and subcortical pathways, and the likelihood of connection for
nTMS-positive vs. nTMS-negative cortical spots. We demonstrated, that the
nTMS-based approach, especially what we call the “single-spot” strategy, is
able to provide a reliable and more detailed reconstruction of the complex
cortico-subcortical language network as compared to the standard DTI-FT. We
believe this technique represents a beneficial new strategy for customized
preoperative planning in patients affected by tumors in presumed language
eloquent location, providing anatomo-functional information to plan language-
preserving surgery
