Donors and Sustainability in the Provision of Financial Services in Nigeria

summary The article discusses some of the issues surrounding sustainability in the provision of financial services by the Diocesan Development Services (DDS) in Nigeria. The article describes the history and growth of DDS within the turbulent social, economic and political conditions in Nigeria, and examines (i) to what extent financial sustainability is an achievable goal for DDS, and (ii) whether donors should play a pro?active role in influencing local decisions. The article analyses the problems faced by DDS when a major donor tried to push it to attain rapidly financial sustainability

Despite the acknowledged importance of this active flux to ocean biogeochemistry, these contributions remain poorly constrained, in part because daily variations in metabolic rates are not considered or are modeled as simple functions of temperature. To address this uncertainty, we sampled the subtropical copepod Pleuromamma xiphias at 4- to 7-h intervals throughout the daily migration and measured rates of oxygen consumption, ammonium excretion, fecal pellet production and metabolic enzyme activity. No significant patterns were detected in rates of oxygen consumption or ammonium excretion for freshly caught animals over the diel cycle. Fecal pellet production was highest during mid-night, consistent with several hours of feeding near the surface. Surface feeding resulted in fecal pellet production at depth in the morning, providing direct evidence that active flux of particulate organic carbon occurs in this region. Electron transport system activity was highest during the afternoon, contrary to our prediction of reduced daytime metabolism. Activity of both glutamate dehydrogenase and citrate synthase increased during early night, reflecting higher capacity for excretion and aerobic respiration, respectively. Overall, these results show that activities of metabolic enzymes vary during diel vertical migration. The surprising observation of elevated afternoon enzyme activity coupled with daytime fecal pellet and ammonium production suggests that additional characterization of the daytime activity of migratory zooplankton is warranted.This work was supported by the National Science Foundation [Grants OCE-1829318 to AEMand LBB, and OCE-1829378 to AMT].

Factors influencing the agronomic performance of the Adapted Yam Minisett Technique in Nigeria – planting date and gender of the farmer

This paper describes the results of 3 year's data from farmers using the Adaptive Yam Minisett Technique (AYMT) to produce seed yams in Nigeria. A total of 30 sites were established each year between 2013 and 2015 in the Idah area (Kogi State) of Nigeria and 58 plots in the Amoke area (Benue State) in 2015. Each site had yam setts (80 to 100 g) untreated and treated with a pesticide ‘dip’ prior to planting and farmers (male and female) were free to select the variety and manage the sites as they wished. In line with previous research, the results suggest that treatment does increase the weight of tubers produced by a sett but not necessarily the number of tubers. Varietal differences were also observed. For the first time, the results suggest that the time of planting does have a significant impact on seed tuber weight, with later planting leading to small tubers. Also, the gender of the farmer had an impact on some of the agronomic variables, with male owners of the site generally producing more and larger tubers per sett planted and sprouted than female owners. Various mechanisms for the latter are discussed in the paper

Post-Acute Effectiveness of Lithium in Pediatric Bipolar I Disorder

This study examined the long-term effectiveness of lithium for the treatment of pediatric bipolar disorder within the context of combination mood stabilizer therapy for refractory mania and pharmacological treatment of comorbid psychiatric conditions

An Open-Label Study of Aripiprazole in Children with a Bipolar Disorder

The purpose of this open-label study was to describe the effectiveness of aripiprazole (APZ) in the treatment of children with bipolar disorders suffering from manic symptomatology

Combination lithium and Divalproex sodium in pediatric bipolarity

ABSTRACT Objective: It has been reported that bipolar disorder may become less responsive to previously effective treatment with each symptomatic relapse. The primary goal of this study was to assess the rate of restabilization after the resumption of lithium (L

An Open-Label Study of Aripiprazole in Children with a Bipolar Disorder

Abstract Objective: The purpose of this open-label study was to describe the effectiveness of aripiprazole (APZ) in the treatment of children with bipolar disorders suffering from manic symptomatology. Method: Symptomatic outpatients (Young Mania Rating Scale [YMRS] score !15) meeting strict, unmodified, Diagnostic and Statistical Manual of Mental Disorders, 4th edition, diagnostic symptom criteria for a bipolar disorder, ages 4-9 years, were eligible. Subjects were treated prospectively with flexible doses of APZ (maximum daily dose of 15 mg/day), for up to 16 weeks or until a priori response criteria were met. Outcome measures included the YMRS, Clinical Global Impressions ScaleSeverity, Children's Global Assessment Scale (CGAS), and the Children's Depression Rating Scale-Revised (CDRS-R). A priori response criteria consisted of 3 of 4 consecutive weeks with (1) CDRS-R <29; (2) YMRS <10; and (3) CGAS >50. Results: Ninety-six children (62 males; mean age of 6.9 (SD ¼ 1.7), received APZ for an average length of treatment of 12.5 (SD ¼ 3.9) weeks. Significant improvements in YMRS, CDRS-R, CGAS, and Clinical Global Impressions Scale-Severity scores ( p < 0.001) were noted at the end of study participation. Sixty of the subjects (62.5%) met a priori response criteria at study's end. The most common side effects noted were stomachache, increased appetite, and headache. Two subjects were removed from the study due to side effects [epistaxis (n ¼ 1); akathisia (n ¼ 1)]. Subjects experienced an average weight gain of 2.4 (SD ¼ 1.9) kg. Conclusion: APZ may be effective in the acute treatment of symptoms of children with bipolar illnesses

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
