Asymmetric Labor Markets, Southern Wages, and the Location of Firms

This paper studies the behavior of firms towards weak labor rights in developing countries (South). A less than perfectly elastic labor supply in the South gives firms oligopsonistic power tempting them to strategically reduce output to cut wages. In an open economy, competitors operating in perfectly competitive labor markets meanwhile enjoy less aggressive competitors and raise output. Finally, competition effect reduces the ex-post output of a relocating firm. These effects reduce relative profitability of the South casting doubts on traditional beliefs that multinationals are attracted to regions with lower wages. Adopting a minimum wage unambiguously enhances Southern competitiveness and welfare

ESTABLISHING RELATIONSHIP BETWEEN WELDING CURRENT AND WELD METAL DEPOSITION RATE FOR SOLID WIRE IN SUBMERGED ARC WELDING PROCESS

Submerged Arc Welding (SAW) process is used to weld large, heavy metal deposition jobs with critical requirements, and this metal joining process alone is used to weld approximately 10% of the deposited weld metal worldwide. Any augmentation in productivity of SAW process, will immensely benefit the welding industry, as this process is widely used on variety of common metals and alloys. This paper focusses on establishing relationship between welding current and productivity (in terms of weld metal deposition rate as an index), for a given filler wire diameter. Productivity rates of most common solid filler wire sizes were studied, at different preset current values, covering full current range through bead-on-plate experiments. At each preset current value, the bead was first optimized for acceptable visual quality, by varying arc travel speed and voltage, then wire feed rate (of acceptable beads) was noted. The current density, heat input and corresponding weld metal deposition rate were calculated for establishing relationships. The established relationships can be effectively used, to estimate productivity from the preset current values, for a given solid wire diameter.</jats:p

Can the straw man speak? An engagement with postcolonial critiques of ‘global cities research’

This paper was published in the journal Dialogues in Human Geography and the definitive published version is available at https://doi.org/10.1177/2043820616675984.This paper engages with postcolonial critiques of global cities research (GCR). We argue that such criticisms tend to be hampered by their tendency to be polemical rather than engaging, as evidenced by both the quasi-systematic misrepresentation of the core objectives of GCR and the skating over of its internal diversity. We present a genealogy of postcolonial critiques starting from Robinson’s (2002) agenda-setting discussion of GCR, followed by an analysis of how her legitimate concerns have subsequently morphed into a set of apparent truisms. These misrepresentations are then contrasted with the purposes, diversity, and critical character of GCR as actually practiced. We interpret this discrepancy to be part of a gradually routinized straw man rhetoric that emerged as an unfortunate rallying point for postcolonial urban scholars. The consequence is that GCR tends to be casually invoked to distinguish one’s own position. We conclude by advocating practices of ‘engaged pluralism’ rather than ‘polemical pluralism’ when doing global urban research and propose that critical realism can provide an important epistemological bridge to make different positions communicate
