3-(4-Chloroanilino)-2,5-dimethylcyclohex-2-en-1-one
In the title compound, C14H16ClNO, the dihedral angle between the benzene ring and the conjugated part of the cyclohexene ring is 61.7 (2)°. Part of the cyclohexene ring and one of the attached methyl groups are disordered over two orientations with occupancies of 0.602 (7) and 0.398 (7). In addition, the crystal studied was a racemic twin [Flack parameter = 0.58 (4)]. In the crystal, the molecules are linked into chains in the b-axis direction by intermolecular N—H⋯O hydrogen bonds. C—H⋯O and C—H⋯Cl interactions are also observed
2,5-Dimethyl-3-[4-(trifluoromethoxy)anilino]cyclohex-2-enone
In the title compound, C15H16F3NO2, the dihedral angle between the benzene ring and the conjugated part of the cyclohexene ring is 60.00 (8)°. The non-conjugated part of the cyclohexene ring and the trifluoromethyl group are both disordered over two sets of sites with occupancies of 0.835 (2) and 0.165 (2). In the crystal, molecules are linked into chains along [010] by intermolecular N—H⋯O hydrogen bonds. Weak intermolecular C—H⋯O interactions also occur
Krey\`ol-MT: Building MT for Latin American, Caribbean and Colonial African Creole Languages
A majority of language technologies are tailored for a small number of
high-resource languages, while relatively many low-resource languages are
neglected. One such group, Creole languages, have long been marginalized in
academic study, though their speakers could benefit from machine translation
(MT). These languages are predominantly used in much of Latin America, Africa
and the Caribbean. We present the largest cumulative dataset to date for Creole
language MT, including 14.5M unique Creole sentences with parallel translations
-- 11.6M of which we release publicly, and the largest bitexts gathered to date
for 41 languages -- the first ever for 21. In addition, we provide MT models
supporting all 41 Creole languages in 172 translation directions. Given our
diverse dataset, we produce a model for Creole language MT exposed to more
genre diversity than ever before, which outperforms a genre-specific Creole MT
model on its own benchmark for 26 of 34 translation directions.Comment: NAACL 202
World cities and peripheral development: The interplay of gateways and subordinate places in Argentina and Ghana’s upstream oil and gas sector
Serving as “gateways”, some world cities tie their wider hinterlands to global networks. The article revisits gateway–hinterland relations against the backdrop of assessments that lead to opposed conclusions on the benefits and shortcomings of integration into the world economy. Referring to the oil and gas sector in Argentina and Ghana, it answers the question of how gateways interact with subordinate places and also uncovers obstacles to peripheral development. The author finds that Accra and Buenos Aires concentrate corporate control. Argentina's capital serves as a gateway for knowledge generation and logistics too. Opportunities for peripheral development in both countries are considerable, albeit largely limited to generic services. Besides a certain concentration of business activities in the gateway cities, more important challenges to peripheral development are typical for small and medium enterprises (insufficient finance and management capabilities, unawareness of business opportunities, and the like). They include rent seeking and subcontracting. The latter leaves local companies in a particularly weak position vis‐à‐vis lead firms. The author argues that while integration into the world economy allows for peripheral development, the corresponding outcomes may not meet everyone's expectations. Related expectations must, therefore, be more down‐to‐earth than overly optimistic statements frequently made by politicians
The Regulation and Expression of the Creatine Transporter: A Brief Review of Creatine Supplementation in Humans and Animals
Creatine monohydrate has become one of the most popular ergogenic sport supplements used today. It is a nonessential dietary compound that is both endogenously synthesized and naturally ingested through diet. Creatine ingested through supplementation has been observed to be absorbed into the muscle exclusively by means of a creatine transporter, CreaT1. The major rationale of creatine supplementation is to maximize the increase within the intracellular pool of total creatine (creatine + phosphocreatine). There is much evidence indicating that creatine supplementation can improve athletic performance and cellular bioenergetics, although variability does exist. It is hypothesized that this variability is due to the process that controls both the influx and efflux of creatine across the cell membrane, and is likely due to a decrease in activity of the creatine transporter from various compounding factors. Furthermore, additional data suggests that an individual's initial biological profile may partially determine the efficacy of a creatine supplementation protocol. This brief review will examine both animal and human research in relation to the regulation and expression of the creatine transporter (CreaT). The current literature is very preliminary in regards to examining how creatine supplementation affects CreaT expression while concomitantly following a resistance training regimen. In conclusion, it is prudent that future research begin to examine CreaT expression due to creatine supplementation in humans in much the same way as in animal models
Incidence of epidural haematoma and neurological injury in cardiovascular patients with epidural analgesia/anaesthesia: systematic review and meta-analysis
Background: Epidural anaesthesia is used extensively for cardiothoracic and vascular surgery in some centres, but not in others, with argument over the safety of the technique in patients who are usually extensively anticoagulated before, during, and after surgery. The principle concern is bleeding in the epidural space, leading to transient or persistent neurological problems. Methods: We performed an extensive systematic review to find published cohorts of use of epidural catheters during vascular, cardiac, and thoracic surgery, using electronic searching, hand searching, and reference lists of retrieved articles. Results: Twelve studies included 14,105 patients, of whom 5,026 (36%) had vascular surgery, 4,971 (35%) cardiac surgery. and 4,107 (29%) thoracic surgery. There were no cases of epidural haematoma, giving maximum risks following epidural anaesthesia in cardiac, thoracic, and vascular surgery of 1 in 1,700, 1 in 1,400 and 1 in 1,700 respectively. In all these surgery types combined the maximum expected rate would be 1 in 4,700. In all these patients combined there were eight cases of transient neurological injury, a rate of 1 in 1,700. (95% confidence interval 1 in 3,300 to 1 in 850). There were no cases of persistent neurological injury (maximum expected rate 1 in 4,600). Conclusion: These estimates for cardiothoracic epidural anaesthesia should be the worst case. Limitations are inadequate denominators for different types of surgery in anticoagulated cardiothoracic or vascular patients more at risk of bleeding
Rational Asymmetric Development: Transfer Pricing and Sub-Saharan Africa's Extreme Poverty Tragedy
Foreign aid, instability and governance in Africa
This study contributes to the attendant literature by bundling governance dynamics and focusing on foreign aid instability instead of foreign aid. We assess the role of foreign aid instability on governance dynamics in fifty three African countries for the period 1996-2010. An autoregressive endogeneity-robust Generalized Method of Moments is employed. Instabilities are measured in terms of variance of the errors and standard deviations. Three main aid indicators are used, namely: total aid, aid from multilateral donors and bilateral aid. Principal Component Analysis is used to bundle governance indicators, namely: political governance (voice & accountability and political stability/no violence), economic governance (regulation quality and government effectiveness), institutional governance (rule of law and corruption-control) and general governance (political, economic and institutional governance). Our findings show that foreign aid instability increases governance standards, especially political and general governance. Policy implications are discussed
