Insights into the social ecological system of the Golden Stream Corridor Preserve in Belize through the assessment of direct use values and benefits

The designation of state and private protected areas around the world has been increasing over the past years. Belize is not an exception to this reality. To date more than 103 protected areas have been recognized into the National Protected Areas System of Belize (NPAS). Private protected areas (PPA) did not become part of Belize’s NPAS until 2015. But long before its legislation, private protected areas have been contributing to conservation and development in Belize. The Golden Stream Corridor Preserve (GSCP) is one of Belize’s exemplary PPA which advocates for conservation through the promotion of sustainable livelihood development and community empowerment. Using the co-evolution model by Pretzsch et al. (2014) as a conceptual framework, direct use values and benefits of the GSCP are assessed to gain insight into its social ecological system. A single case (embedded) case study design was used to execute this assessment at three buffering communities: Medina Bank, Golden Stream and Indian Creek. A total of 60 households, representing 10% of household leaders in each community were interviewed using a semi structured questionnaire. Community leaders were also interviewed to discover customary rules relating to resource use and the history of each community. The direct use value assessment revealed that the GSCP only contributes to values associated with tourism and employment. These values were disproportionately distributed across buffering communities; with Indian Creek perceiving all values associated with tourism, and Golden Stream from employment. Medina Bank saw no direct use values from the GSCP. Community forests and lands were found to be the exclusive source of direct use values associated with the utilization of forest products. Sustainable livelihood development opportunities and community empowerment were the most reported benefits arising from the management of the GSCP. The adoption and contribution of livelihood strategies were however met with positive and negative criticism by community members. Results from this evaluation epitomizes the importance of SES thinking in protected areas. Customary rules of resource use have contributed positively to the integrity of the GSCP. The impending threat of land use change and population growth at buffering communities calls for the creation of enabling environments for the adoption of sustainable livelihood through community participation, consultation, monitoring and evaluation.:CHAPTER ONE 1.

HAUNTING SECRETS: THE PHANTOM OF SHAME LEGACIES THAT KEEP ON GIVING

This paper reviews the connections between unspoken transgenerational trauma, shame, and the concepts of hauntology and transgenerational phantom and looks at ways writing can reveal the traces of shame-as-affect. Some transgenerational trauma narratives do not distinguish between trauma-as-event and shame-as-affect/emotion, which can lead to a conflation of the two. This paper proposes that hauntology (the encroachment of an "other) and the transgenerational phantom (the metaphysical manifestation of others' shameful secrets), as conceptual scaffolds, are relevant to deciphering and depicting shame-as-affect distinct to the traumatic event via an understanding of the way speech and writing can bear the traces of shame-as-affect. To demonstrate, this paper provides a close reading of Arundhati Roy's The god of small things and highlights how cryptographic writing—the fissures and distortions in language—can inform the representation of shame in trauma narratives

Points of comparison : what indicating gestures tell us about the origins of signs in San Juan Quiahije Chatino sign language

New languages emerge under rare conditions, when deaf children who cannot access the vocal-auditory language(s) used around them invent visual-manual communication systems of their own. Such homesign or family sign systems have simple structures but nevertheless show the hallmarks of language, including a stable lexicon of signs composed of meaningful, recombinable elements. Prior research has found that many of these elements are invented by signers, though some are adapted from the gestural input received from hearing interlocutors. The current project returns to this claim, examining the influence of gestures on the structure of two emerging family sign languages used in a rural, indigenous community in Oaxaca, Mexico. It focuses on foundational, visually accessible ‘indicating gestures’ such as pointing that direct the addressees attention to a region in physical space. Three linked studies were performed to investigate whether indicating gestures have internal structure that is accessible to deaf signers, and whether such structure is incorporated into their emerging languages. In the first, the spontaneous, speech-linked indicating gestures of hearing people were examined for internal structure. They were found to comprise three recombinable elements that, through systematic modulations in form, convey information about the direction and distance of targets. A second study looked for a relationship between the form of indicating gestures and the features of the speech that accompanies them. No such relationship was found, suggesting that the meaningful modulation of the gesture features occurs independently from speech. The final study compared the forms and meanings of two deaf signers’ indicating gestures with those of the hearing participants. Signers were found to use the direction and elbow height features, but not the handshape features, from the conventional indicating system. These findings reveal that indicating gestures, often described as holistic, non-composite signals, in fact exhibit an internal structure that can be incorporated into an emerging signed language. Interestingly, they also reveal that not all features of gestures—even ones that exhibit clear patterning—will be adopted by signers, perhaps because gesture features must be both systematically patterned and visually iconic for signers to interpret them as meaningful.Linguistic

Synthetic versus biological mesh-related erosion after laparoscopic ventral mesh rectopexy. A systematic review

Purpose: This review reports the incidence of mesh-related erosion after ventral mesh rectopexy to determine whether any difference exists in the erosion rate between synthetic and biological mesh. Methods: A systematic search of the MEDLINE and the Ovid databases was conducted to identify suitable articles published between 2004 and 2015. The search strategy capture terms were laparoscopic ventral mesh rectopexy, laparoscopic anterior rectopexy, robotic ventral rectopexy, and robotic anterior rectopexy. Results: Eight studies (3,956 patients) were included in this review. Of those patients, 3,517 patients underwent laparoscopic ventral rectopexy (LVR) using synthetic mesh and 439 using biological mesh. Sixty-six erosions were observed with synthetic mesh (26 rectal, 32 vaginal, 8 recto-vaginal fistulae) and one (perineal erosion) with biological mesh. The synthetic and the biological mesh-related erosion rates were 1.87% and 0.22%, respectively. The time between rectopexy and diagnosis of mesh erosion ranged from 1.7 to 124 months. No mesh-related mortalities were reported. Conclusion: The incidence of mesh-related erosion after LVR is low and is more common after the placement of synthetic mesh. The use of biological mesh for LVR seems to be a safer option; however, large, multicenter, randomized, control trials with long follow-ups are required if a definitive answer is to be obtained

Incremental Visual-Inertial 3D Mesh Generation with Structural Regularities

Visual-Inertial Odometry (VIO) algorithms typically rely on a point cloud representation of the scene that does not model the topology of the environment. A 3D mesh instead offers a richer, yet lightweight, model. Nevertheless, building a 3D mesh out of the sparse and noisy 3D landmarks triangulated by a VIO algorithm often results in a mesh that does not fit the real scene. In order to regularize the mesh, previous approaches decouple state estimation from the 3D mesh regularization step, and either limit the 3D mesh to the current frame or let the mesh grow indefinitely. We propose instead to tightly couple mesh regularization and state estimation by detecting and enforcing structural regularities in a novel factor-graph formulation. We also propose to incrementally build the mesh by restricting its extent to the time-horizon of the VIO optimization; the resulting 3D mesh covers a larger portion of the scene than a per-frame approach while its memory usage and computational complexity remain bounded. We show that our approach successfully regularizes the mesh, while improving localization accuracy, when structural regularities are present, and remains operational in scenes without regularities.Comment: 7 pages, 5 figures, ICRA accepte

Development of a multiblock procedure for automated generation of two-dimensional quadrilateral meshes of gear drives

This article describes a new multiblock procedure for automated generation of two-dimensional quadrilateral meshes of gear drives. The typical steps of the multiblock schemes have been investigated in depth to obtain a fast and simple way to mesh planar sections of gear teeth, allowing local mesh refinement and minimizing the appearance of distorted elements in the mesh. The proposed procedure is completed with two different mesh quality enhancement techniques. One of them is applied before the mesh is generated, and reduces the distortion of the mesh without increasing the computational time of the meshing process. The other one is applied once the mesh is generated, and reduces the distortion of the elements by means of a mesh smoothing method. The performance of the proposed procedure has been illustrated with several numerical examples, which demonstrate its ability to mesh different gear geometries under several meshing boundary conditions

The Effects of Fish Trap Mesh Size on Reef Fish Catch off Southeastern Florida

Catch and mesh selectivity of wire-meshed fish traps were tested for eleven different mesh sizes ranging from 13 X 13 mm (0.5 x 0.5") to 76 x 152 mm (3 X 6"). A total of 1,810 fish (757 kg) representing 85 species and 28 families were captured during 330 trap hauls off southeastern Florida from December 1986 to July 1988. Mesh size significantly affected catches. The 1.5" hexagonal mesh caught the most fish by number, weight, and value. Catches tended to decline as meshes got smaller or larger. Individual fish size increased with larger meshes. Laboratory mesh retention experiments showed relationships between mesh shape and size and individual retention for snapper (Lutjanidae), grouper (Serranidae), jack (Carangidae), porgy (Sparidae), and surgeonfish (Acanthuridae). These relationships may be used to predict the effect of mesh sizes on catch rates. Because mesh size and shape greatly influenced catchability, regulating mesh size may provide a useful basis for managing the commercial trap fishery

Tetrahedral mesh improvement using moving mesh smoothing, lazy searching flips, and RBF surface reconstruction

Given a tetrahedral mesh and objective functionals measuring the mesh quality which take into account the shape, size, and orientation of the mesh elements, our aim is to improve the mesh quality as much as possible. In this paper, we combine the moving mesh smoothing, based on the integration of an ordinary differential equation coming from a given functional, with the lazy flip technique, a reversible edge removal algorithm to modify the mesh connectivity. Moreover, we utilize radial basis function (RBF) surface reconstruction to improve tetrahedral meshes with curved boundary surfaces. Numerical tests show that the combination of these techniques into a mesh improvement framework achieves results which are comparable and even better than the previously reported ones.Comment: Revised and improved versio
