Internationalisation and migrant academics: the hidden narratives of mobility
Internationalisation is a dominant policy discourse in higher education today. It is invariably presented as an ideologically neutral, coherent, disembodied, knowledgedriven policy intervention - an unconditional good. Yet it is a complex assemblage of values linked not only to economic growth and prosperity, but also to global citizenship, transnational identity capital, social cohesion, intercultural competencies and soft power (Clifford and Montgomery 2014; De Wit et al. 2015; Kim 2017; Lomer 2016; Stier 2004). Mobility is the sine qua non of the global academy (Sheller 2014). International movements, flows and networks are perceived as valuable transnational and transferable identity capital and as counterpoints to intellectual parochialism. Fluidity metaphors abound as an antidote to stasis e.g. flows, flux and circulations (Urry 2007). For some, internationalisation is conceptually linked to the political economy of neoliberalism and the spatial extension of the market, risking commodification and commercialisation (Matus and Talburt 2009). Others raise questions about what/whose knowledge is circulating and whether internationalisation is a form of re-colonisation and convergence that seeks to homogenise higher education systems (Stromquist 2007). Internationalisation policies and practices, it seems, are complex entanglements of economic, political, social and affective domains. They are mechanisms for driving the global knowledge 2 economy and the fulfilment of personal aspirations (Hoffman 2009). Academic geographical mobility is often conflated with social mobility and career advancement (Leung 2017). However, Robertson (2010: 646) suggested that ‘the romance of movement and mobility ought to be the first clue that this is something we ought to be particularly curious about.
The Migration State in the Global South: Nationalizing, Developmental and Neoliberal Models of Migration Management
How do states in the Global South manage cross-border migration? This article identifies Hollifield’s “migration state” as a useful tool for comparative analysis yet notes that in its current version the concept is limited, given its focus on economic immigration in advanced liberal democracies. We suggest a framework for extending the “migration state” concept by introducing a typology of nationalizing, developmental, and neoliberal migration management regimes. The article explains each type and provides illustrative examples drawn from a range of case studies. To conclude, it discusses the implications of this analysis for comparative migration research, including the additional light it sheds on the migration management policies of states in the Global North
LIQUID-LIQUID EQUILIBRIA OF TERNARY-SYSTEMS OF WATER PLUS ACETONE AND C-5-ALCOHOL AND C-8-ALCOHOL AT 298-K, 303-K AND 308-K
Ternary liquid-liquid phase equilibria (LLE) of water and acetone with 1-octanol, 2-octanol, 1-pentanol and isopentanol (3-methyl-1-butanol) at 298, 303 and 308 K are presented. With the exception of water + acetone + 1-octanol at 303 K, these systems have not been previously investigated at these temperatures. The data are successfully correlated using the NRTL model. The UNIFAC predictive model was also tested with the various group parameter databases
Characterization of pore structure of Turkish coals
Pore structure of coal has a great influence on its behavior during mining, preparation, and utilization; Characterization of the pore structure of twelve Turkish coals from different geographic locations and with carbon contents varying between 61 and 84% (on dry ash-free basis) was carried out using different techniques. The volume and area of macropores were determined by mercury intrusion porosimetry. Mesopore volumes and areas were determined by N-2 gas adsorption at 77 K using the Barrett-Joyner-Halenda (BJH) method. Brunauer-Emmet-Teller (BET) areas were calculated using the same data. Micropore volumes and areas were determined by the application of the Dubinin-Radushkevich (DR) equation to the CO2 adsorption data at 298 K. True and apparent densities of coals were measured by helium-and mercury displacement. Pore size distributions were evaluated using data thus obtained. Small-angle X-ray scattering (SAXS) technique was also employed to determine the surface area of some samples. The highest BET surface area, 34 m(2)/g, was found for Tuncbilek coal which has a significant mesoporous volume; while the corresponding values for the rest of the coals were less than 7 m(2)/g. DR surface areas which varied in the range 19-115 m(2)/g were larger than BET areas indicating molecular sieve character of coals. SAXS areas were larger than DR areas for some coals which can be explained by the presence of closed pores in these samples. For some coals having relatively small porosities, SAXS areas were found to be smaller; than DR areas which is attributed-to the inability of the method to distinguish ultramicropores of molecular dimensions which are probably accessible to CO2 molecules. SAXS surface area of Illinois No. 6 coal and a synthetic char (Spherocarb) were also measured and the values found agreed well with the ones given in the literature
The Role of Cytokines in the Immunopathogenesis of Toxoplasmosis
WOS: 000272651300025Objective: Infection caused by the obligatory intracellular parasite Toxoplasma gondii is generally asymptomatic in immunocompetent individuals but may be life-threatening in immunosuppressed patients and congenitally infected fetus. Scientists believed that the pathogenesis of the infection could be well established if the relation between cellular and humoral immune response was documented. Material and Methods: Starting from this point we tried to establish this relation, by measuring the production of Interferon-gamma (IFN-gamma) (T(h)1 cytokine) and interleucine (IL)-5 (T(h)2 cytokine) in supernatants of peripheral blood mononuclear cells (PBMC) after in vitro specific T gondii antigen stimulation in 19 patients that were grouped according to their anti-Toxoplasma IgM and IgG levels. Results: In our study, we observed that the level of IL-5 synthesis was higher than IFN-gamma in the initial phase of the infection; as the specific IgG titers started to rise, IFN-gamma synthesis increased and suppressed the synthesis of IL-5. As the infection became chronic a de, crease in the IFN-gamma synthesis and a slight increase in IL-5 synthesis were noted. In our seronegative patient group, cytokine production pattern showed mainly T(h)0 subgroup profile. Conclusion: As a result, we suggest that evaluation of antigen specific cytokine synthesis parallel to humoral response in the different stages of toxoplasmosis would be beneficial both in the diagnosis and in follow-up
Physical and chemical properties of selected Turkish lignites and their pyrolysis and gasification rates determined by thermogravimetric analysis
Pyrolysis and CO(2)-gasification behavior of lignites representing four different deposits in Turkey were investigated by Thermogravimetric Analysis (TGA) in the temperature range from 750 degrees C to 1000 degrees C. The rates of pyrolysis and CO(2)-gasification were evaluated from the corresponding TGA profiles. As expected, maximum pyrolysis rates for each coal were shown to be constant with respect to the final carbonization temperature. Lignites used in this study are from the tertiary period, chosen from major coal deposits in Turkey and their carbon contents are in the range of 60-70% (daf) based on ultimate analysis. They have shown different gasification reactivities under similar conditions and the reactivity sequence was found to be temperature dependent
