To sustain its agricultural output, the U.S. relies heavily on imports of potash. Using two different methodologies, this study finds that U.S. import demand falls by approximately four percent in the short run and nine percent in the long run for a 10% rise in the potash import price. Price transmission with leading exporter Canada is imperfect, with U.S. prices rising only 7.7% in the short run when Canadian prices rise by 10%. The findings suggest that policies such as import tariffs would raise costs for U.S. agricultural producers because there are few potash substitutes.
Raqqa Governorate, Syria has recently been affected by overlapping conflicts related to the Syrian Civil war and occupation by ISIS, resulting in widespread displacement and disruption of economic livelihoods. However, little information is currently known about mental health needs and risk factors among women. Therefore, this study sought to examine potential risk factors for depressive symptoms among married women living in northern Syria.
Methods.
Data were collected between March and April 2018 as part of an evaluation of an International Rescue Committee cash transfer program targeted toward vulnerable households. Using cross-sectional data from 214 married women participating in the program, linear regression models were generated to explore the associations between depressive symptoms [nine-item Patient Health Questionnaire (PHQ-9)] and its potential risk factors, including food insecurity, perceived deprivation of basic needs [the Humanitarian Emergency Settings Perceived Needs Scale (HESPER) scale], and past-3-month intimate partner violence (IPV).
Results.
The average depressive symptom score was 10.5 (s.d.: 4.9; range: 2–27). In the final adjusted model, any form of recent IPV (β = 2.25; 95% CI 0.92–3.57; p = 0.001), severe food insecurity (β = 1.62; 95% CI 0.27–2.96; p = 0.02) and perceived needs (β = 0.38; 95% CI 0.18–0.57; p = 0.0002) were associated with an increase in depressive symptoms.
Conclusion.
Study findings point to the need to address the mental health needs of women in conflict-affected areas of Syria. Programming to address risk factors for depression, including IPV and other factors associated with daily stressors such as food insecurity and deprivation of basic needs, may be effective in reducing depression in this population.
Women living in war-affected contexts face high levels of gender-based violence, including intimate partner violence (Stark & Ager, 2011). Despite well-documented negative consequences, including posttraumatic stress disorder (PTSD) (Garcia-Moreno et al. 2006; Steel et al. 2009), evidence remains thin regarding intervention effectiveness to mitigate consequences in these settings.
Methods.
This study used a two-armed parallel pilot randomized controlled trial to compare the impact of a group savings only (control) to gender dialogue groups added to group savings (treatment) on women's symptoms of PTSD in northwestern Côte d'Ivoire. Eligible Ivorian women (18+ years, no prior experience with group savings) were invited to participate and 1198 were randomized into treatment groups.
Results.
In the ITT analyses, women in the treatment arm had significantly fewer PTSD symptoms relative to the control arm (β: −0.12; 95% CI: −0.20 to −0.03; p = 0.005). Partnered women in the treatment arm who had not experienced intimate partner violence (IPV) at baseline had significantly fewer PTSD symptoms than the control arm (β = −0.12; 95% CI: −0.21 to −0.03; p = 0.008), while those who had experienced IPV did not show significant differences between treatment and control arms (β = −0.09; 95% CI: −0.29 to 0.11; p = 0.40).
Conclusions.
Adding a couples gender discussion group to a women's savings group significantly reduced women's PTSD symptoms overall. Different patterns emerge for women who experienced IPV at baseline v. those who did not. More research is needed on interventions to improve mental health symptoms for women with and without IPV experiences in settings affected by conflict.
Improving children's learning and development in conflict-affected countries is critically important for breaking the intergenerational transmission of violence and poverty. Yet there is currently a stunning lack of rigorous evidence as to whether and how programs to improve learning and development in conflict-affected countries actually work to bolster children's academic learning and socioemotional development. This study tests a theory of change derived from the fields of developmental psychopathology and social ecology about how a school-based universal socioemotional learning program, the International Rescue Committee's Learning to Read in a Healing Classroom (LRHC), impacts children's learning and development. The study was implemented in three conflict-affected provinces of the Democratic Republic of the Congo and employed a cluster-randomized waitlist control design to estimate impact. Using multilevel structural equation modeling techniques, we found support for the central pathways in the LRHC theory of change. Specifically, we found that LRHC differentially impacted dimensions of the quality of the school and classroom environment at the end of the first year of the intervention, and that in turn these dimensions of quality were differentially associated with child academic and socioemotional outcomes. Future implications and directions are discussed.
Conflict-affected communities face poverty and mental health problems, with sexual violence survivors at high risk for both given their trauma history and potential for exclusion from economic opportunity. To address these problems, we conducted a randomized controlled trial of a group-based economic intervention, Village Savings and Loans Associations (VSLA), for female sexual violence survivors in the Democratic Republic of Congo.
Methods.
In March 2011, 66 VSLA groups, with 301 study participants, were randomized to the VSLA program or a wait-control condition. Data were collected prior to randomization, at 2-months post-program in June 2012, and 8-months later for VSLA participants only. Outcome data included measures of economic and social functioning and mental health severity. VSLA program effect was derived by comparing intervention and control participants' mean changes from baseline to 2-month follow-up.
Results.
At follow-up, VSLA study women reported significantly greater per capita food consumption and significantly greater reductions in stigma experiences compared with controls. No other study outcomes were statistically different. At 8-month follow-up, VSLA participants reported a continued increase in per capita food consumption, an increase in economic hours worked in the prior 7 days, and an increase in access to social resources.
Conclusions.
While female sexual violence survivors with elevated mental symptoms were successfully integrated into a community-based economic program, the immediate program impact was only seen for food consumption and experience of stigma. Impacts on mental health severity were not realized, suggesting that targeted mental health interventions may be needed to improve psychological well-being.
By 2009, two decades of war and widespread displacement left the majority of the population of Northern Uganda impoverished.
Methods.
This study used a cluster-randomized design to test the hypothesis that a poverty alleviation program would improve economic security and reduce symptoms of depression in a sample of mostly young women. Roughly 120 villages in Northern Uganda were invited to participate. Community committees were asked to identify the most vulnerable women (and some men) to participate. The implementing agency screened all proposed participants, and a total of 1800 were enrolled. Following a baseline survey, villages were randomized to a treatment or wait-list control group. Participants in treatment villages received training, start-up capital, and follow-up support. Participants, implementers, and data collectors were not blinded to treatment status.
Results.
Villages were randomized to the treatment group (60 villages with 896 participants) or the wait-list control group (60 villages with 904 participants) with an allocation ration of 1:1. All clusters participated in the intervention and were included in the analysis. The intent-to-treat analysis included 860 treatment participants and 866 control participants (4.1% attrition). Sixteen months after the program, monthly cash earnings doubled from UGX 22 523 to 51 124, non-household and non-farm businesses doubled, and cash savings roughly quadrupled. There was no measurable effect on a locally derived measure of symptoms of depression.
Conclusions.
Despite finding large increases in business, income, and savings among the treatment group, we do not find support for an indirect effect of poverty alleviation on symptoms of depression.
The role of Campylobacter jejuni as the triggering agent of Guillain–Barré syndrome (GBS) has not been reassessed since the end of the 1990s in France. We report that the number of C. jejuni-related GBS cases increased continuously between 1996 and 2007 in the Paris region (mean annual increment: 7%, P = 0·007).
A polynomial-time randomised algorithm for uniformly generating forests in a dense graph is presented. Using this, a fully polynomial randomised approximation scheme (fpras) for counting the number of forests in a dense graph is created.
Further treatment with clozapine is contraindicated in any patient who has previously experienced leucopenia or neutropenia during clozapine therapy.
Aims
To investigate the results of such a rechallenge in 53 patients.
Method
An analysis was made of the demographic, haematological and outcome data of patients in the UK and Ireland who were rechallenged with clozapine following leucopenia or neutropenia during previous clozapine therapy.
Results
Of 53 patients who were rechallenged, 20 (38%) experienced a further blood dyscrasia. In 17 of these 20 patients (85%) the second blood dyscrasia was more severe(P<0.001), in 12(60%) it lasted longer (P=0.0368) and in 17 (85%) it occurred more quickly on rechallenge (P<0.001). Of the original 53 patients, 55% (29 patients) are still receiving clozapine.
Conclusions
No clear risk factor for repeat blood dyscrasias was identified. Despite this, after risks and benefits have been considered, rechallenge may well be justified in some patients.
An abundant nuclear phosphoprotein, the La autoantigen, is
the first protein to bind all newly synthesized RNA polymerase
III transcripts. Binding by the La protein to the 3′ ends
of these RNAs stabilizes the nascent transcripts from
exonucleolytic degradation. In the yeasts Saccharomyces
cerevisiae and Schizosaccharomyces pombe, the
La protein is required for the normal pathway of tRNA maturation.
Experiments in which the human protein was expressed in S.
pombe have suggested that phosphorylation of the La protein
regulates tRNA maturation. To dissect the role of phosphorylation
in La protein function, we used mass spectrometry to identify
three sites of serine phosphorylation in the S. cerevisiae
La protein Lhp1p. Mutant versions of Lhp1p, in which each of
the serines was mutated to alanine, were expressed in yeast
cells lacking Lhp1p. Using two-dimensional gel electrophoresis,
we determined that we had identified and mutated all major sites
of phosphorylation in Lhp1p. Lhp1p lacking all three
phosphorylation sites was functional in several yeast strains
that require Lhp1p for growth. Northern blotting revealed no
effects of Lhp1p phosphorylation status on either pre-tRNA
maturation or stabilization of nascent RNAs. Both wild-type
and mutant Lhp1 proteins localized to both nucleoplasm and
nucleoli, demonstrating that phosphorylation does not affect
subcellular location. Thus, although La proteins from yeast
to humans are phosphoproteins, phosphorylation does not appear
to be required for any of the identified functions of the S.
cerevisiae protein.
