Wood anatomy and hydraulic architecture of stems and twigs of some Mediterranean trees and shrubs along a mesic-xeric gradient.
No full textWoody species populating the major Mediterranean ecosystems in the world are characterized by different levels of adaptation to the seasonal Mediterranean climate conditions. Many species of these ecosystems show wood features that allow high efficiency of transport when water is available, while maintaining hydraulic safety during drought periods. This study focuses on the anatomy of juvenile and mature wood of some species representative of continuous sequences of Mediterranean vegetation formations according to gradients of water availability, from xeric to relatively mesic: Cistus monspeliensis L., Rhamnus alaternus L., Myrtus communis L., Pistacia lentiscus L., Olea europaea L., Quercus ilex L., Fraxinus ornus L. and Ostrya carpinifolia L. Twigwood collected in Southern Italy was anatomically compared with the stemwood of the same species represented in the reference slide collection of the National Herbarium of the Netherlands (Lw). The "hydraulic distance" between the wood of main stems and twigs was estimated on the basis of suites of anatomical features related to water efficiency/safety. Although some attributes (i.e. porosity and type of imperforate tracheary elements) were similar in young twigs and older rings, other traits (i.e. vessel frequency and size) evidenced the different hydraulic properties of twig and stemwood. The difference between juvenile and mature structures was large in the species of the mesic end of the gradient while it was relatively small in those more xeric. This tendency is in agreement with the habit gradient from medium-sized trees to small evergreen/drought deciduous shrubs according to decreasing water availability in Mediterranean vegetation types

No full textNational audienceLa violente crise politico-militaire qui secoue la Syrie depuis mars 2011 fait ressortir des fragilités géopolitiques qu'un corset autocratique avait tenté de dissimuler. La question agraire et hydraulique dans ce pays est parmi les sujets à observer de près, car elle met en lumière une partie importante de l'action du Baas depuis son arrivée au pouvoir en 1963

Evaluating the Effectiveness of the BAAS Program in Reducing Stunting in Takalar Regency
No full textIntroduction: The complexity of stunting reduction interventions cannot be addressed by the government alone. The state appreciates contributions from all stakeholders, including the community. The Foster Parents for Stunting Children (BAAS) program provides a platform for stakeholder participation in accelerating stunting reduction. As a relatively new program, a review is needed to assess its impact. This study aims to evaluate the effectiveness of the BAAS program in Takalar Regency in 2023.
Methods: This study uses quantitative research with a cross-sectional approach. Data analysis was conducted to determine how much the success measure of the BAAS program based on the target approach (output). In this study, the test used was the Wilcoxon signed rank test to see the impact (outcome) of how significant the program was to reduce the prevalence of stunting.
Results: There is a statistically significant difference between the Z-score TB/U and BB/U before and after the BAAS program with a mean Z-score TB/U before the program of -2.78 and BB/U of -1.83 and a mean Z-score TB/U after the program of -0.40 and BB/U of -0.91. Based on the p-value of Z-score TB/U and BB/U showed a very small value for Z-score TB/U of 0.000 (<0.05). and BB/U of <0.001. This suggests that the program is effective for improving nutritional status and can reduce stunting and wasting in Takalar District.
Conclusion: The BAAS Program successfully demonstrated its effectiveness in improving the nutritional status of children in Takalar District. The Wilcoxon Signed Rank Test results also showed a statistically significant difference between the Z-score values before and after the program with a p value <0.05, confirming that the BAAS Program is effective in improving nutrition and reducing stunting in Takalar District. BAAS is an effective intervention model with the potential for replication and expansion, serving as a reference for sustainable and inclusive community-based stunting prevention policies

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
