Species identification of the psammophilous tenebrionid beetles Phaleria acuminata Juster, 1852 and Phaleria bimaculata (Linnaeus, 1767) from central…
2013
Dominating global arid environments, from desert to coastal dunes, most Tenebrionidae are highly specific in their habitat preferences and display limited dispersal potential, thus exhibiting a remarkable degree of regional genetic and morphological differentiation. The tenebrionid genus Phaleria is speciose and widely distributed, with P. acuminata and P. bimaculata having a wide Mediterranean distribution, with numerous morphological differentiations at population level, often described as different taxa of doubtful taxonomical significance. In order to investigate the variability of the central Mediterranean populations of P. bimaculata and P. acuminata and to compare the results obtaine…
Isolation and Characterization of High-Efficiency Rhizobia From Western Kenya Nodulating With Common Bean.
2021
Common bean is one of the primary protein sources in third-world countries. They form nodules with nitrogen-fixing rhizobia, which have to be adapted to the local soils. Commercial rhizobial strains such as Rhizobium tropici CIAT899 are often used in agriculture. However, this strain failed to significantly increase the common bean yield in many places, including Kenya, due to the local soils’ low pH. We isolated two indigenous rhizobial strains from the nodules of common bean from two fields in Western Kenya that have never been exposed to commercial inocula. We then determined their ability to fix nitrogen in common beans, solubilize phosphorus, and produce indole acetic acid. In greenhou…
Does Microfinance Cause or Reduce Suicides? Policy Recommendations for Reducing Borrower Stress
2011
At a time when suicides by microfinance borrowers in Andhra Pradesh are extensively discussed, this paper makes an initial tentative exploration into the impact of microfinance on suicides. Does MF reduce or increase suicides? Data limitations imply methodological limitations and provisional conclusions. The literature review, starting with Emile Durkheim, of research on suicides brings out the importance of psychological factors, divorce, and unemployment. We investigate time series data on suicides in India and find a just significantly positive correlation with male suicide rates and slightly negative correlations (not significant) with female suicide rates – but no relation between micr…
Leaf water potential meaning of different modalities of measurements
2004
<p style="text-align: justify;">An experiment on Syrah in the Ecotron design of the AGRO Montpellier/INRA campus vineyard, with the control of different water regimes, allowed to test the physiological meaning and the field of application of different modalities of leaf water potential measurements : predawn and daily potential for leaves in a normal micro-environment (which keep all of their interest and generality), « stem » potential (which must be called differently and reserved to particular conditions) for shadow enveloped leaves. Field observations on Syrah and Merlot confirm the interest of some methods.</p>
Mobility decline in old age.
2012
Mobility is important for community independence. With increasing age, underlying pathologies, genetic vulnerabilities, physiological and sensory impairments, and environmental barriers increase the risk for mobility decline. Understanding how mobility declines is paramount to finding ways to promote mobility in old age. peerReviewed
Contribution of musculoskeletal pain to postural balance in community-dwelling people aged 75 years and older.
2010
Background. Balance is among the most important prerequisites for safe and independent mobility. Whether musculoskeletal pain is related to standing balance impairment has received limited attention. The aim of this study was to examine the association of musculoskeletal pain with the control of balance in older people. Methods. A total of 605 participants aged 75 years and older (mean age 80.4, 71 % women) were interviewed about presence and severity of musculoskeletal pain. Balance was measured by a force platform, and impaired balance was defined as a high sway velocity moment or inability to maintain semitandem standing. Results. Musculoskeletal pain was reported by 48% of the participa…
Perceived barriers in the outdoor environment and development of walking difficulties in older people
2012
SIR—Older people with mobility limitations often report more barriers in their outdoor environment than people with intact mobility [1]. However, it is uncertain whether older people perceive their environment as problematic because of their mobility limitations or whether the environmental barriers precede incident mobility limitation, as most studies have been limited to cross-sectional analyses [2–5]. Only a few longitudinal studies have shown that barriers in the outdoor environment, such as poor street conditions, poor lighting and heavy traffic, increase the risk for overall functional loss [6, 7] and decrease physical activity participation [8]. More knowledge is needed about the cha…
Life-Space Mobility in Parkinson's Disease: Associations with Motor and Non-Motor Symptoms.
2019
Background To describe life-space mobility and explore associations of motor and non-motor symptoms with life-space mobility in people with Parkinson’s disease (PD). Methods About 164 community-dwelling persons with PD (mean age 71.6 years, 64.6% men) received a postal survey and a subsequent home visit. Motor assessments included perceived walking difficulties (Walk-12G), mobility (Timed Up and Go test), motor symptoms (UPDRS-III), and freezing of gait (item 3, FOG-Qsa). Non-motor symptoms included depressive symptoms (GDS-15), pain, fatigue (NHP-EN), and global cognition (MoCA). Life-space mobility was assessed with the life-space assessment (LSA). Calculations included composite score (r…
The Personal Nature of Individual Criminal Responsibility and the ICC Statute
2007
By affirming criminal responsibility of the individual, the ICC Statute recognizes a distinction from the international responsibility of states, which is the basis of modern international criminal law. The importance of the principle is evident not only in the breadth and analytical nature of the provision dealing with it, i.e. Article 25 of the Statute, but by its being placed in the part of the Statute devoted to the ‘General Principles of Criminal Law’. After an introductory consideration of the context of the Article and of its general implications, this article analyses the contents of the regulation and the type of responsibility outlined in it. The principle that emerges could be ca…
Physical Activity Among Children With Congenital Heart Defects in Germany: A Nationwide Survey
2020
Objective: In children with congenital heart defects (CHD), a sedentary lifestyle should be avoided and usually WHO recommendations on physical activity (PA) are supposed to be followed. In order to obtain representative data of the actual amount of PA (and potential influencing factors) in children with CHD we performed a nationwide online survey.Methods: All patients aged 6–17 years registered in the German National Register for CHD were contacted by email and asked to participate in the survey using the comprehensive questionnaire of the “Motorik-Modul” from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), thus allowing the comparison with a repres…
