Different isolation levels are required to ensure various degrees of data consistency and currency to read-only transactions. Current definitions of isolation levels like Conflict Serializability, Update Serializability or External Consistency/Update Consistency are not appropriate for processing read-only transactions since they lack any currency guarantees. To correct the problem, we propose ...

A general-purpose isiZulu text-to-speech (TTS) system was developed, based on the “Multisyn” unit-selection approach supported by the Festival TTS toolkit. The development involved a number of challenges related to the interface between speech technology and linguistics – for example, choosing an appropriate set of phonetic units, producing reliable pronunciations, and developing appropriate co...

We present evidence that importing is a driver of international technology transfer. Using a detailed panel of Indonesian manufacturers, our analysis shows that firms in industries supplying importintensive sectors have higher productivity than other firms. This finding suggests that linkages through vertical supply relationships are the channel through which import-driven technology transfer o...

This paper presents a frequency modulation based readout circuit for the measurement of skin conductance or resistance. A charge pump based frequency-to-voltage converter circuit with adjustable sensitivity is used to convert the frequency shifts due to skin resistance changes into voltage variations. The readout circuit improves the measurement accuracy and artifact rejection in measurements o...

This paper examines the impact of inflows of foreign knowledge on economic development, in the context of different institutional development and differing levels of human capital. We employ threshold regression analysis based on Hansen (2000) to determine whether there is cross-country heterogeneity in the flows of foreign knowledge from advanced industrialised countries to a group of 57 devel...

To what extent do firms go abroad to access technology available in other locations? This paper examines whether and when state technical capabilities attract foreign investment in manufacturing from 1987-1993. We find that on average state R&D intensity does not attract foreign direct investment. Most investing firms are in lower-tech industries and locate in low R&D intensity states, suggesti...

This paper reports on a part of work for the UNIDO initiative on technology transfer for sustainable industrial development. The proposed technology transfer framework, adapted from the East Asian late industrialisers model, identifies two categories of countries requiring support for enhancing their technological capabilities: (a) very late industrialisers (“low income” developing countries), ...

Article history: Received 13 June 2012 Received in revised form 23 May 2013 Accepted 26 May 2013 Available online 4 June 2013 Despite the impressivemagnitude of inward FDI in China, empirical studies on its spillover effects are relatively scarce and have failed to find conclusive evidence. By exploring a vast firm-level panel dataset, this study aims to test empirically whether the horizontal ...

Laser micro-dissection permits isolation groups of cells from heterogeneous tissue sections under direct microscopic visualization. This technology not only allows isolation of homogenous subpopulation of cells but also allows immunophenotypically similar cells for RNA/ DNA or protein extraction for downstream applications like western blot, mass spectrophotometry, real time quantitative polyme...
