Spatiotemporal Changes and Driving Factors of Ecosystem Health in the Qinling-Daba Mountains
No full textRapid industrialization and urbanization have accelerated land-use changes in mountainous areas, with dramatic impacts on ecosystem health. In particular, the Qinling-Daba Mountains, as China’s central water tower, ecological green lung, and biological gene bank, have rich resource endowments and extremely high ecological value and are an important protective wall to China’s ecological security. Therefore, understanding the level of ecosystem health and its drivers in the research area contributes to the conservation and restoration of the mountain ecosystem. Based on remote sensing image data and land-use data from 2000 to 2020, we explored the spatial characteristics of ecosystem health, and supplemented with socio-economic data to explore its driving factors. The results show that (1) the ecosystem health in the study area has been continuously improved during the study period, and the regional differences in ecological organization are the most prominent; (2) the level of ecosystem health in the Qinling-Daba Mountains has been spatially improved from the peripheral areas to the central area, showing significant spatial autocorrelation and local spatial aggregation; (3) the ecosystem health is influenced by a combination of natural and anthropogenic factors, among which the negative effect of GRDP is mainly concentrated in the eastern region, the negative effect of the proportion of built-up land gradually spreads to the western region, and the positive effect of the proportion of forest land has a large scale. This study contributes to a better understanding of ecosystem health in mountainous counties in China and provides useful information for policymakers to formulate ecological and environmental management policies
Discovery of radiolaria from Upper Cretaceous Oceanic Red Beds in Daba, Kangmar and its paleogeographic implication
No full textA group of varicolored marine deposits, including red colored beds, are widespread in the Kangmar area, southern Tibet. They are lithologically similar to the Upper Cretaceous Oceanic Red Beds (CORBs) (the Chuangde Formation) outcropping at other localities in southern Tibet. At Daba locality, they are mainly composed of intercalated pelagic red clays and reddish colored pelagic limestones. Micropaleontologic study of the strata led to the discovery of radiolarians in siliceous rocks and siliceous limestones. Radiolaria preservation is mostly satisfactory and fifty-four species from forty-nine genera were identified. These allow recognition of three main radiolarian assemblages: Cavaspongia califoniaensis - Xitus spicularius assemblage. Praeconoanyomma lipmanae - Clathropyrgus titthium assemblage, and Lithostrobus punctulatus - Lithocampe marinae assemblage. Occurrence of these radiolarian assemblages indicate a Campanian age of the CORBs at Daba, corroborated by co-occurring planktic foraminifers. Radiolarian and foraminiferal microfossil evidence and lithology of the strata indicate that the sediments were deposited at the lower continental margin of the Indian continental plate and in an adjacent abyssal oceanic basin. The discovery of radiolarians from the CORBs at Daba area contributes to the paleogeographic interpretation of Late Cretaceous strata in southern Tibet and the Tethyan Himalaya. Unanswered is the remaining question: Was it the difference in palaeoceanography, such as ocean circulation, or plate tectonics, which resulted in the CORBs in the Tethyan Himalaya being younger than similar deposits in the western Tethys, where the deposition of this lithofacies had already begun in the Turonian? To answer this question more detailed biostratigraphic studies in southern Tibet are needed. (C) 2011 Elsevier B.V.

The “body of ritual” transformed: discourses and actions in the Daba rituals among the Na (Moso)
No full textAbstract Anthropologists have adopted different approaches in order to analyze discourses in ritual context. This paper, based on long-term field investigations, aims to discuss the Na’s Daba rituals from the angle of enunciation. By describing the system of ritual knowledge, namely the “body of ritual” to the Na, and by presenting the transformations of such a system in the ritual “mukrabu,” the author argues that the decomposition and the arrangement of ritual actions are essentially accomplished by the Daba’s performances of enunciation, which represents a crucial aspect of ritual processes. In this perspective, modes of various practices of discourse should constitute an important dimension of ritual studies

La Escuela Pública Itinerante y su relación con la Carpa Blanca : formas comunicacionales del gremio docente
No full textIntroducción\nEn esta investigación se analizará, en su dimensión comunicacional, el fenómeno de protesta llevado a cabo por el gremio docente entre 9 de abril y el 4 de julio de 2017, conocido como Escuela Pública Itinerante. Estableceremos una comparación con la situación de 1997-1999, explorando los paralelismos entre ambos contextos políticos y con el fenómeno de la “Carpa Blanca”, buscando analizar en qué medida ésta funciona como ícono de la lucha docente en el marco de la actual estrategia comunicacional del gremio. A los fines del análisis, se ha efectuado un recorte temporal que está delimitado por el inicio del conflicto en diciembre de 2016, cuando el entonces Ministro de Educación de la Nación, Esteban Bullrich, anunció la suspensión de la paritaria nacional, y el 4 de julio de 2017, fecha en la cual los gremios aceptaron el aumento salarial del 27,4% ofrecido por la gobernadora de la Provincia de Buenos Aires, María Eugenia Vidal. Tanto la Carpa Blanca como la Escuela Itinerante constituyeron respuestas comunicacionales de protesta alternativas al paro, ambas surgidas de la Confederación de Trabajadores de la Educación de la República Argentina (Ctera) en dos momentos históricos diferentes cuyos contextos son en algunos aspectos asimilables y en otros distinguibles. En 1997, año en que se instaló la Carpa frente al Congreso, el gobierno de Carlos Menem daba sus últimos pasos luego de una década en el poder. Fueron años de ajuste y reformas neoliberales que llevaron al país al colapso de 2001. En el 99, cuando asumió el nuevo gobierno radical, la Ctera levantó la Carpa habiendo logrado parcialmente sus objetivos: visibilizar el conflicto ante la sociedad civil y los medios de comunicación y obtener alguna mejora salarial. Como consecuencia paralela, también contribuyó al desgaste del menemismo, pero éste ya se encontraba en su fase agónica. En 2017, los sindicatos docentes también reaccionan a las medidas de ajuste, sin embargo el gobierno al que se enfrentan se encuentra en pleno ascenso. Se trata de contextos parecidos en cuanto a las políticas económicas y educativas que desde el Estado se intentan llevar adelante y a las cuales los docentes se oponen, pero muy diferentes en cuanto al nivel de aceptación en los medios y la sociedad civil. El ciclo del macrismo, si se toma como referencia la duración de las últimas experiencias de gobiernos democráticos – con la excepción del radicalismo y la debacle institucional de 2001- recién estaría empezando. Esta diferencia de contexto es fundamental para entender las disparidades en el funcionamiento y los resultados de ambas experiencias comunicacionales del gremio docente.Fil: García, Cecilia Mariel.

Pengaruh Aerobic Exercise Terhadap Aktivitas Serum Creatin Kinase Myocardial Band (CK-MB) pada Lansia Pasca Stroke
No full textStroke can cause changes in the heart, which are associated with excessive activation of the sympathetic nervous system as a response to damage occurring in the insular cortex. Cardiac biomarkers such as creatine kinase myocardial band (CK-MB) show increased levels in some patients with acute cerebrovascular accidents without direct cardiac injury. CK-MB activity has been found to increase in the early phase of patients with ischemic stroke, subarachnoid hemorrhage, and head trauma. Objective: To determined the effect of aerobic exercise on serum creatine kinase myocardial band (CK-MB) activity in elderly post-stroke patients. Methods: This was a pre-experimental study with a one-group pretest-posttest design. The study involved 16 elderly post-stroke respondents who received aerobic exercise using a static cycle at light to moderate intensity for 10-15 minutes, 2-3 times per week, over the course of 4 weeks. CK-MB activity was evaluated using the Enzyme-Linked Immunosorbent Assay (ELISA) method. Results: There was a significant effect of aerobic exercise on serum CK-MB activity in elderly post-stroke patients, with a p-value of 0.000 or p < 0.05. The mean serum CK-MB level increased to 29.43µL, while the mean serum CK-MB level decreased to 23.12 µL after receiving aerobic exercise with a static cycle for 4 weeks. Conclusion: Aerobic exercise using a static cycle at light to moderate intensity for 10-15 minutes, 2-3 times per week, over the course of 4 weeks, had a significant effect on serum creatine kinase myocardial band (CK-MB) activity in elderly post-stroke.

No full textStroke pada lansia menduduki peringkat kedua penyebab kematian dan kecacatan terbesar hampir diseluruh dunia serta menjadi masalah kesehatan global. Pasca stroke mayoritas pasien mengalami penurunan fungsi trunk yang akan berpengaruh pada kemampuan fungsionalnya sehingga pasien akan mengalami kesuitan dalam melakukan gerakan-gerakan fungsional yang sangat dibutuhkan dalam aktivitas sehari-hari. Penurunan fungsi trunk juga menjadi penyebab buruknya postur pada pasien pasca stroke dan juga menyebabkan ketergantungan pasien. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian latihan stabilitas inti dengan metode ADIM (Abdominal Draw in Manuever) terhadap fungsi trunk dan aktivitas fungsional pada lansia pasca stroke. Dua hipotesis utama diuji dalam penelitian ini: pertama, apakah latihan stabilitas inti berdampak signifikan terhadap fungsi trunk pada lansia pasca stroke; dan kedua, apakah latihan stabilitas inti berdampak signifikan terhadap aktivitas fungsional pada lansia pasca stroke. Penelitian ini menggunakan pendekatan kuantitatif dengan desain eksperimental dengan rancangan one group pretes dan posttest. Kelompok yang diteliti adalah pasien hemiparese poststroke yang diberikan latihan stabilitas inti dengan metode ADIM.Hasil analisis menunjukkan bahwa terdapat pengaruh yang signifikan dari latihan stabilitas inti dengan metode ADIM terhadap peningkatan fungsi trunk dan aktivitas fungsional pada lansia pasca stroke. Temuan ini menunjukkan bahwa latihan stabilitas inti dapat menjadi intervensi yang efektif dalam program rehabilitasi untuk meningkatkan kualitas hidup lansia pasca stroke
