Intrinsic and extrinsic quality of data for open data repositories
Aurora González-Vidal,Alfonso P. Ramallo-González,Antonio F. Skarmeta 한국통신학회 2022 ICT Express Vol.8 No.3
This work assesses the quality of Internet of Things data not only as an intrinsic quality on how well it represents the related phenomenon but also, on how much information it contains to educate an artificial entity. The quality metrics here proposed are tested with real datasets. Also, they are implemented on OpenCPU, so the open data repositories can use them off-the-shelf to rate their datasets without computational cost and minimum human intervention, making them more attractive to potential users and gaining visibility and impact.

Microvascular reconstruction frequently requires anastomosis outside of the zone of injury for successful reconstruction. Multiple options exist for pedicle lengthening including vein grafts, arteriovenous loops, and arteriovenous bundle interposition grafts. The authors performed a systematic review of arteriovenous bundle interposition grafts to elucidate indications and outcomes of arteriovenous grafts in microvascular reconstruction. A systematic review of the literature was performed using targeted keywords. Data extraction was performed by two independent authors, and descriptive statistics were used to analyze pooled data. Forty-four patients underwent pedicle lengthening with an arteriovenous graft from the descending branch of the lateral circumflex femoral artery. Most common indications for flap reconstruction were malignancy (n¼12), trauma (n¼7), and diabetic ulceration (n¼4). The most commonly used free flap was the anterolateral thigh flap (n¼18). There were five complications, with one resulting in flap loss. Arteriovenous bundle interposition grafts are a viable option for pedicle lengthening when free flap distant anastomosis is required. The descending branch of the lateral circumflex femoral artery may be used for a variety of defects and can be used in conjunction with fasciocutaneous, osteocutaneous, muscle, and chimeric free flaps.

Expression of recombinant proteins in Escherichia coli often leads to formation of inclusion bodies (IB). If a recombinant protein contains one or more disulfide bonds,protein refolding and thiol oxidation reactions are required to recover its biological activity. Previous studies have demonstrated that molecular chaperones and foldases assist with the in vitro protein refolding. However, their use has been limited by the stoichiometric amount required for the refolding reaction. In search of alternatives to facilitate the use of these folding biocatalysts in this study, DsbA, DsbC,and the apical domain of GroEL (AD) were fused to the carbohydrate-binding module CBDCex of Cellulomonas fimi. The recombinant proteins were purified and immobilized in cellulose and used to assist the oxidative refolding of denatured and reduced lysozyme. The assisted refolding yields obtained with immobilized folding biocatalysts were at least twice of those obtained in the spontaneous refolding,suggesting that the AD, DsbA, and DsbC immobilized in cellulose might be useful for the oxidative refolding of recombinant proteins that are expressed as inclusion bodies. In addition, the spontaneous or assisted refolding kinetics data fitted well (r2 > 0.9) to a previously reported lysozyme refolding model. The estimated refolding (kN)and aggregation (kA) constants were consistent with the hypothesis that foldases assisted the oxidative refolding of lysozyme by decreasing protein aggregation rather than increasing the refolding rate.
Asserting Women’s Rights and Well Being in the Age of Populism and Misogyny in the Philippines

Filipino women take pride in having gained substantial progress in advancing women’s rights and gender equality in the country particularly in the area of legislative reforms. However, such reforms, when viewed in the context of an increasingly globalized world, and the state’s adherence to neo-liberal policies have in fact been quite limited. In addition, the politics of patronage and oligarchic rule and the monopoly of economic and political power by a few have persisted despite the democratization efforts after EDSA revolution and the presence of strong social movements in the country. The lecture briefly examines the effects of globalization processes alongside the deterioration of democratic processes since EDSA on women’s assertions of their rights, voice and well-being. The recent emergence of authoritarian populist/misogynist regime of Duterte illustrates the fragility of hard won gains by women and of social movements in general. The present climate of impunity and the regression of many rights and freedoms and constriction of democratic spaces for citizens in general and women in particular poses serious challenges but also opportunities for women’s struggle to achieve genuine political and economic empowerment. Concrete examples of women’s organizing and collective action will be discussed.
A Portrait of Development Economics in the Last Sixty Years
Diana Barros,Aurora A.C. Teixeira 중앙대학교 경제연구소 2021 Journal of Economic Development Vol.46 No.2
The field of Development Economics has experienced significant innovativeness and dynamism in recent years. However, a quantitative review on its precise outlook and evolution has yet to be accomplished. Based on bibliometric techniques were applied to all (9430) the articles and reviews published on ‘economic development’, from 1952 to 2019, we demonstrate that: 1) the yearly publishing rate is quite irregular, observing a noticeable rise from the 1990s onwards; 2) dominance of USA-affiliated researchers among the most prolific and influential authors; 3) increasing relevance of the topics ‘Economic policy’, ‘Institutions and governance’, and ‘Environmental issues’ over time; 4) noticeable trend in economic development towards a post-normal science with a shift from exclusively ‘appreciative’ studies to more ‘formal and empirical’ studies, evidencing an important stage of maturation in the field; 5) the empirical analyses are mostly focused on developed countries, in which the African continent and countries are rather neglected.
