Financial services for resilience: how to assess the impacts
This is the final version. Available from BRACED via the link in this recordkey messages
• Niger is a least developed country prone
to recurrent drought, which affects a large
share of the population and results in
severe food security issues.
• Support mechanisms, including access to
adequate financial resources, are important for
individuals and communities to better prepare
for and cope with climate extremes.
• Village savings and loan associations
(VSLAs) are implemented as a means to
support rural communities, address livelihood
shocks and strengthen social capital.
• Two innovative research methods – financial
diaries and serious games – have been
carried out in Niger, to help support a better
understanding of VSLAs’ contribution to
climate resilience.
• These innovative tools reveal
behavioural changes that help complete our
understanding of how VSLAs can contribute
to resilience-building in dimensions that
are often unexplored, including (i) gender
empowerment; (ii) social trust; and
(iii) natural resource management.
• This paper paves the way for further analysis
of the role of VSLAs in building communities’
resilience by documenting the linkages
between financial inclusion and resilience
to climate extremes.
• These methods, based on community
participation, provide a complementary
alternative to traditional monitoring and
evaluation methods. They contribute
to the ‘monitoring–evaluation–learning’
trinity by blending evaluation and learningDFI
Femoral and tibial bone torsions associated with medial femoro-tibial osteoarthritis. Index of cumulative torsions
AbstractFrontal plane varus deviation is one of the mechanisms hypothesized to be involved in the pathogenesis of medial compartment osteoarthritis of the knee. But only a few authors have suggested a role for tibial and femoral torsion. In the current study, CT scan was used to measure bone torsion. The torsional morphology of the lower limb was defined by the “index of cumulative torsions” (ICT). The resulting values were compared to the frontal angular deviation data. The effects of tibial and femoral torsion on the position of the lower limb during the stance phase of walking and the consequences for the knee are discussed
Electromechanical characterization of piezoelectric actuators subjected to a variable preloading force at cryogenic temperature
A dedicated apparatus was designed and constructed for studying the electromechanical behavior of prototype piezoelectric actuators subjected to a variable preloading force at cryogenic temperatures. This device was successfully used for testing a piezoelectric actuator of PICMA type from PI™, for T in the range 2 K-300 K. The dielectric properties as well as dynamic properties were measured including the actuator characteristics when used as force sensor. The corresponding data are reported and discussed
Developing and assessing a new web-based tapping test for measuring distal movement in Parkinson's disease: a Distal Finger Tapping test
Disability in Parkinson's disease (PD) is measured by standardised scales including the MDS-UPDRS, which are subject to high inter and intra-rater variability and fail to capture subtle motor impairment. The BRadykinesia Akinesia INcoordination (BRAIN) test is a validated keyboard tapping test, evaluating proximal upper-limb motor impairment. Here, a new Distal Finger Tapping (DFT) test was developed to assess distal upper-limb function. Kinetic parameters of the test include kinesia score (KS20, key taps over 20 s), akinesia time (AT20, mean dwell-time on each key) and incoordination score (IS20, variance of travelling time between key taps). To develop and evaluate a new keyboard-tapping test for objective and remote distal motor function in PD patients. The DFT and BRAIN tests were assessed in 55 PD patients and 65 controls. Test scores were compared between groups and correlated with the MDS-UPDRS-III finger tapping sub-scores. Nine additional PD patients were recruited for monitoring motor fluctuations. All three parameters discriminated effectively between PD patients and controls, with KS20 performing best, yielding 79% sensitivity for 85% specificity; area under the receiver operating characteristic curve (AUC) = 0.90. A combination of DFT and BRAIN tests improved discrimination (AUC = 0.95). Among three parameters, KS20 showed a moderate correlation with the MDS-UPDRS finger-tapping sub-score (Pearson's r = - 0.40, p = 0.002). Further, the DFT test detected subtle changes in motor fluctuation states which were not reflected clearly by the MDS-UPDRS-III finger tapping sub-scores. The DFT test is an online tool for assessing distal movements in PD, with future scope for longitudinal monitoring of motor complications
Volunteering in a hybrid institutional and organizational environment: an emerging research agenda
Traditionally, volunteers are core participants in classic voluntary associations; however, the organizational context of volunteering has changed significantly in recent decades through the proliferation of new and hybrid settings of participation that mingle roles and rationalities of civil society, state and market. In this chapter, I examine the consequences of this organizational change for the nature and functions of volunteering by means of a literature review
SIRT7 mediates L1 elements transcriptional repression and their association with the nuclear lamina
Altres ajuts: La Marató de TV3.Long interspersed elements-1 (LINE-1, L1) are retrotransposons that hold the capacity of self-propagation in the genome with potential mutagenic outcomes. How somatic cells restrict L1 activity and how this process becomes dysfunctional during aging and in cancer cells is poorly understood. L1s are enriched at lamin-associated domains, heterochromatic regions of the nuclear periphery. Whether this association is necessary for their repression has been elusive. Here we show that the sirtuin family member SIRT7 participates in the epigenetic transcriptional repression of L1 genome-wide in both mouse and human cells. SIRT7 depletion leads to increased L1 expression and retrotransposition. Mechanistically, we identify a novel interplay between SIRT7 and Lamin A/C in L1 repression. Our results demonstrate that SIRT7-mediated H3K18 deacetylation regulates L1 expression and promotes L1 association with elements of the nuclear lamina. The failure of such activity might contribute to the observed genome instability and compromised viability in SIRT7 knockout mice. Overall, our results reveal a novel function of SIRT7 on chromatin organization by mediating the anchoring of L1 to the nuclear envelope, and a new functional link of the nuclear lamina with transcriptional repression
Magnetoelectric MnPS3 thiophosphate as a new candidate for ferrotoroidicity
We have revisited the magnetic structure of manganese phosphorus trisulfide
MnPS3 using neutron diffrac- tion and polarimetry. MnPS3 undergoes a transition
toward a collinear antiferromagnetic order at 78 K. The resulting magnetic
point-group breaks both the time reversal and the space inversion thus allowing
a linear magnetoelectric coupling. Neutron polarimetry was subsequently used to
prove that this coupling provides a way to manipulate the antiferromagnetic
domains simply by cooling the sample under crossed magnetic and electrical
fields, in agreement with the nondiagonal form of the magnetoelectric tensor.
In addition, this tensor has, in principle, an antisymmetric part that results
in a toroidic moment and provides with a pure ferrotoroidic compound
