El recuento año tras año de este conjunto migrante es un trabajo indispensable para conocer la dinámica de la población. Los censos poblacionales terrestres ofrecen un invalorable conocimiento de sus fluctuaciones y migraciones. Se brindan particularidades de la elefanterÃa de Valdés y sus poblaciones, aspectos biológicos relevantes y otras lecturas sugeridas
Más que siete mares, un océano
Se analiza la necesidad de conservación de los ecosistemas oceánicos mundiales, y la urgencia de crear áreas protegidas en mar abierto. Los siete mares inspiran imágenes de vastedad, de grandiosa expansión, de variedad y tolerancia casi infinitas. Siempre en el marco de la metáfora, este trabajo se aparta de la visión de los siete mares para apoyar a la de 'un solo océano'. En lenguaje más formal, el objetivo es promover el pensamiento ecosistémico integrado, difundir el mensaje de que el océano es uno, agotable, e incapaz de resisitir el abuso ambiental sostenido. El artÃculo incluye definiciones, información sobre el primer Ärea Marina Protegida (AMP) en Mar abierto en el Atlántico sudoccidental, Naumuncurá, Banco Burdwood y finaliza con otras lecturas sugeridas
TOWARDS A NOVEL APPROACH TO GEODESIGN ANALYTICS
The adoption of sustainability principles in current European regulatory framework which affect
spatial planning and environmental protection, such as Directive 2001/42/C, introduced the
need for collaboration and participation in spatial planning practices aiming at achieving more
evidence-based, transparent and democratic decision making. However, the involvement of a
wide range of actors, along with traditional collaborative and participatory methods, makes
it often diffi cult to grasp the dynamics which drive the process towards the fi nal decision.
Emerging design methodologies and increased recourse to advanced information technologies
promise unprecedented opportunities not only for applying a system approach and coordinating
involved actors, but also for tracking the evolution of the design alternatives toward the fi nal
plan. In this context, this paper explores the potential offered by the collaborative Planning
Support System Geodesignhub to ease and record the process workfl ow of geodesign studies.
The paper describes underlying theories, research questions formulation and the fi rst results
of the analysis of empirical data on the Cagliari Geodesign case study. The set of variables and
relations identifi ed in this research endeavor represents the fi rst effort towards the development
of an operation framework for geodesign process analysis, which may potentially contribute to
clarify the relationships between the knowledge base and the actors in the planning process.
The aim is to earning a deeper understanding of the process dynamics for more informed,
transparent, and democratic planning, design and decision-making.

Reproduction capabilities of penalized hyperbolic-polynomial splines
This paper investigates two important analytical properties of
hyperbolic-polynomial penalized splines, HP-splines for short. HP-splines,
obtained by combining a special type of difference penalty with
hyperbolic-polynomial B-splines (HB-splines), were recently introduced by the
authors as a generalization of P-splines. HB-splines are bell-shaped basis
functions consisting of segments made of real exponentials and linear functions multiplied by these exponentials,
and . Here, we show that these type of
penalized splines reproduce function in the space , that is they fit exponential data exactly. Moreover, we show
that they conserve the first and second 'exponential' moments.Comment: 11 pages, 2 figure
Predicting Partisan Redistricting Disputes
Partisan redistricting disputes are relatively rare occurrences. This paper explores the factors that lead to partisan disputes over congressional redistricting plans. In previous work single party control of both houses of the state legislature and the governorship emerged as a key correlate of partisan redistricting in the 1980s. This paper presents an interactive statistical model of partisan redistricting plans. The basic conclusion is that in addition to single party control, the nature of the voting role and the political competitiveness of the states effect the likelihood of partisan redistricting
Integrating Green-Infrastructures Design in Strategic Spatial Planning with Geodesign
In the last decades green infrastructure planning, design, and management have been widely recognized as a way to contribute to reach higher levels of sustainability of development. However, often green infrastructures are considered in a sectoral way, while their design should be more integrated within comprehensive planning and design. The paper proposes the use of geodesign methods and technology to support the early phases of integrated strategic territorial planning, in order to enrich the relationships between the design of green infrastructure and of the other relevant systems via more comprehensive planning and design, and by applying systems thinking. A case study developed with architecture and engineering students under the umbrella of the International Geodesign Collaboration is used, to demonstrate how with intensive geodesign workshops it is possible to create spatially explicit design scenarios which take into account the relationships between green infrastructure and other territorial systems and dynamics. A set of analyses on the case study results of the two scales is used to demonstrate the assumption. It is also argued that geodesign intensive workshops can, in a very short time, contribute to raising the awareness among the participants of collaborative design to the importance of green infrastructure in strategic territorial planning
Early maladaptive schemas, emotion regulation difficulties, and alexithymia : A systematic review and meta-analysis
Background
Emotion regulation is an integral part of the schema therapy model. The aim of this systematic review and meta-analysis was to synthesize the evidence on the associations between early maladaptive schemas (EMSs), difficulties with emotion regulation and alexithymia.
Method
PsycINFO, PubMed and CINAHL Complete databases were searched on 28 May 2022 and 3 February 2023 in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Included studies were in English, in peer-reviewed journals and reported on the association between one or more of the 18 EMSs or five schema domains and emotion regulation difficulties or alexithymia. Methodological quality was assessed using the Appraisal Tool for Cross-Sectional Studies. Meta-analyses were conducted to examine difficulties with emotion regulation and alexithymia as correlates of each EMS and domain.
Results
A total of 19 studies published between 2008 and 2022 were included (Pooled N = 5957). Difficulties with emotion regulation were positively correlated with all 18 EMSs (range: entitlement r(7) = .28, 95% CI [.13, .42] to negativity pessimism r(5) = .53, 95% CI [.23, .74]) and schema domains (range: impaired limits r(5) = .34, 95% CI [.08, .56] to disconnection rejection r(5) = .44, 95% CI [.33, .73]). Alexithymia was positively correlated with the other-directedness domain (r(2) = .40, 95% CI [.09, .64]) and 16 of the 18 EMSs (range: unrelenting standards r(5) = .21, 95% CI [.12, .28] to emotional inhibition r(5) = .50, 95% CI [.34, .63]).
Conclusions
The findings suggested that almost all 18 EMSs are implicated in emotion regulation difficulties and alexithymia, particularly those relating to unmet needs for attachment and autonomy
Rationale and practical techniques for mouse models of early vein graft adaptations
Mouse models serve as relatively new yet powerful research tools to study intimal hyperplasia and wall remodeling of vein bypass graft failure. Several model variations have been reported in the past decade. However, the approach demands thoughtful preparation, selected sophisticated equipment, microsurgical technical expertise, advanced tissue processing, and data acquisition. This review compares several described models and aims (building on our personal experiences) to practically aid the investigators who want to utilize mouse models of vein graft failure.Clinical RelevanceSurgical revascularization via vein grafting offers immediate and often dramatic end organ benefit. However, substantial percentages of vein conduits placed develop stenosis or fail, often early. Mechanistic studies of the complex interplay between the biologic and physical forces that drive failure have been hampered by limited quantity and quality of clinical specimens, and the inability of systems such as computer models and cell culture to mimic the clinical circumstance. This review summarizes the power and limitations of mouse vein graft models, and it includes practical experience-based advice for researchers aiming to utilize this tool
Long-Term COVID: Case Report and Methodological Proposals for Return to Work
Almost two years after the beginning of the SARS-CoV-2 pandemic, the knowledge of which in the infectious and therapeutic spheres is constantly evolving, attention paid to the medicolegal aspects linked to this emergency phenomenon has mainly focused on the liability implications falling on healthcare personnel. With regard to the medicolegal assessment of the outcomes of COVID-19 illness, although it is a procedure that is commonly used, and although references in the assessment tables in force have been adhered to, a specific assessment protocol has not been standardized that takes into account, from an objective point of view, the degree of severity of the long-term residual outcomes and their impact on the social and working lives of subjects. This shortcoming appears to be attributable to the immediate need to categorize the results of COVID-19, but, in our opinion, it deserves an in-depth study and protocols to enable evaluation committees to draw up an assessment as precisely as possible and that is free of gaps, which could be the subject of legal disputes. The aim of the present work, in light of a worldwide problem, is to arrive at specific and univocal evaluation criteria for COVID-19 disease outcomes, applicable in different operational contexts of reemployment
The video endoscopy inguinal lymphadenectomy for vulvar cancer: A pilot study
Objective This prospective pilot study aims to validate feasibility, efficacy and safeness of the innovative technique of video endoscopy inguinal lymphadenectomy (VEIL) and compare it to open inguinal lymphadenectomy (OIL) in the staging and treatment of vulvar cancer (VC). Material and methods All patients affected by VC suitable for bilateral inguinal-femoral lymphadenectomy were prospectively enrolled and submitted to VEIL on one side and OIL contralaterally, sparing the saphenous vein. The surgical and post-surgical data were collected. Univariate analysis included chi square analysis or Fisher's exact test, when appropriate for categorical variables, and the Student t test and Mann–Whitney test when appropriate for continuous variables. Results Between October 2014 and June 2015 fifteen patients were valuable for the study. Although nodal retrieval was comparable for both procedures, operative time was higher after VEIL. No intraoperative complications were observed in both techniques. Postoperative complications were observed in 3 and 2 cases for OIL and VEIL respectively. One patient needed reoperation after OIL for wound necrosis and infection. According to Campisi's stage, lymphedema resulted significantly to be lower after VEIL (p = 0.024). Conclusions Waiting for larger series and longer follow-up data, the VEIL seems to be feasible allowing a radical removal of inguinal lymph nodes as well as OIL with lower morbidity
