FDI and Export Participation of Local Firms in Africa: The Case of the Kenyan Garment Industry [PDF]
FDI in the garment sector has been the single case of large-scale manufacturing investment in African low-income countries since the 1990s. While FDI has triggered the development of local industries in many developing countries, it has not yet been ...

On the Determinants of the Reach of Innovation-related Collaboration in Small Firms [PDF]
This paper takes as its starting point an item of relatively recent academic orthodoxy: the insistence that ‘…interactive learning and collective entrepreneurship are fundamental to the process of innovation’ (Lundvall, 1992, p. 9).

High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

The growing demand for lightweight, nontoxic, and multifunctional gamma shielding materials has intensified efforts to find alternatives to conventional lead and aluminum‐based protectants. In this work, we develop epoxy quartz fabric composites reinforced with cobalt chloride (CoCl2) microparticles, fabricated via hand lay‐up with varying filler ...

The "potential" face of absorptive capacity. An empirical investigation for an area of 3 European countries [PDF]
This paper draws on the multi-dimensional characterization of absorptive capacity (AC) to empirically investigate the antecedents and the effects of its "potential" dimension (PAC): i.e., the firm's capacity of acquiring and assimilating external ...

High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Labor absorptive capacity of export expansion and import substitution in Egypt, 1954 to 1970 [PDF]
In the post war era, much has been said about the role of the foreign trade sector in affecting the rate and the level of domestic economic growth in the group of LDCs. The impact of exports in particular received the lion's share of attention.
