Published: December 2022

Las emisiones de gases de efecto invernadero (GEI), son una preocupación latente para todos los países del mundo, por esto, muchos de los países forman parte de la creación de tratados, acuerdos y normas que permitan concientizar y plantearse objetivos por el bien común. Las estimaciones de los factores determinantes dirigido a las emisiones de CO2, se evidencia mediante la descomposición media logarítmica (LMDI) que permite conocer la variación de estas emisiones. El método antes mencionado presenta gran robustez para la estimación de este tipo de análisis, la descomposición de los factores de mix energético (Mix), índice de carbonización (Ic), intensidad energética (Ie), actividad económica (Act) y poblacional (P) aplicado a dos de los sectores más representativos del Ecuador (Transporte e Industrial) en cuanto al consumo de energía, evidencia que entre 2000 – 2020 las emisiones en el sector transporte han aumentado 5,56 Mt de CO2, mientras que en el sector industrial las emisiones muestran una reducción de 1,83 Mt de CO2. El estudio realizado evidencia que los factores determinantes en los sectores del transporte e industrial son el mix energético, índice de carbonización e intensidad energética. El análisis LMDI aplicado, nos permite describir las emisiones de CO2 mediante la descomposición desagregada de factores y la participación de combustibles de origen fósil de cada sector en estudio.

Published: December 2022

Esse artigo tem por objetivo principal tematizar o papel do currículo escolar no reconhecimento e valorização da identidade sociocultural de alunos oriundos de comunidades tradicionais, a partir dos resultados da pesquisa de pós-doutorado desenvolvida no Programa de Ciência Ambiental da Universidade de São Paulo que teve como recorte espacial a região do Vale do Ribeira, local onde se concentra o maior número de comunidades tradicionais do estado de São Paulo, incluindo quilombolas, caboclos, indígenas e caiçaras. Partindo do princípio de que a escola deve ser o espaço da diversidade e entendendo que a identidade sociocultural dos povos e comunidades tradicionais é estruturada a partir do seu modo de vida e, portanto, atrelada ao território em que vivem e à forma como utilizam os recursos naturais, analisaremos em que medida o currículo de Geografia para as escolas públicas do estado de São Paulo, em vigor de 2011 até 2020, contemplou essas questões.

Green marketing is a process of producing environment friendly product. Such type of products that are safe from different hazards. The aim of the study is to measure the antecedents affecting consumers’ green purchase intention towards green products special reference with Nikaweratiya Divisional Secretary area, Kurunegala District. This study uses four dimensions as the independent variable of antecedents such as green purchase attitudes, green perceived values, green perceived trust, and ecological knowledge, while green purchase intention was taken as the dependent variable. For this study, 250 questionnaires were distributed. Further, the researcher used convenience sampling methods to select the sample from Nikaweratiya Divisional Secretariate area. The Pearson’s correlation analysis showed that the green purchase attitudes, green perceived values, green perceived trust and ecological knowledge had a medium positive relationship with green purchase intention. Regression analysis indicated that there was a significant positive impact on green purchase intention towards green products.
A STUDY ON THE FREQUENCY RESPONSE OF A COMPOSITE PRE-STRESSED SYSTEM UNDER AN INCLINED HARMONIC LOADING
Authors: DAŞDEMİR Ahmet

Goal for the present research is investigating the dynamic behaviors regarding forced vibration of an elastic composite body on the rigid ground for four different material designations. For this purpose, the effects of the initial stress state and frequency response parameter on the forced vibration of the model are studied. Based on the linearized theory of elasticity, the nonlinear forced vibration of composite material on the rigid ground is considered. The nonlinear governing equations are linearized and boundary-contact conditions are derived using Hamilton’s principle. Total energy functional is constructed based on the principle of the variational formulation, and then the forced vibration of elastic composite plate-strip is analyzed using the finite element method (FEM). Moreover, the numerical examples related to the influences of important problem factors on our mathematical model are given. The observations show that the selection of more soft material in the upper layers has a great potential for the structural stability of the system. For the softer upper layer relatively, the wave oscillation in the plate-strip exhibits becomes more regular. In addition, the resonance values of the system decrease with the increase of the initial compressing parameter but with the initial stretching parameter.

Malé, the capital of the Republic of Maldives, is established on an island of about 6.8 square kilometres, with a maximum relief of 2.7 m and a population of 236,000 inhabitants. It is amongst the most densely populated areas on Earth and located virtually at sea-level. This study focuses on the late Pleistocene-Holocene evolution of Malé island that recently formed as part of the discontinuous North Malé Atoll rim. Understanding the formation of Malé Island is relevant in predicting its future in the context of accelerating rates of sea-level rise in the next centuries due to anthropogenic global warming. Analyses of two boreholes up to 35 m-long, published information from additional boreholes drilled on Malé Island and a high-resolution multi-beam bathymetric survey acquired along its upper slopes and deep surroundings were available for this study. Two distinct sedimentary units were recovered from the boreholes. Facies analyses of the lower unit reveal an overall deepening coralgal reef that accumulated probably during the previous interglacial (Marine Isotope Stage = MIS 5e) and which was subsequently altered by meteoric diagenesis during a 100 kyr-long time of exposure. The upper unit consists of Holocene unconsolidated coralgal accumulation, unconformably overlying the lower karstified coralgal MIS 5e unit. The upper unit, protected behind a karstified late Pleistocene reef, was initiated at ~8200 yr BP and vertically grew 25 m-high until 6510 yr BP in the northern part of the Malé Island area, which at the time was a karstified limestone island with a central geomorphological depression. The narrow, 30 to 35 m-deep, newly formed central faro lagoon started to fill ~ 5500 yr BP, when a reef initiated on top of the southern highest Pleistocene karstified reef and sea-level rise stalled. The infilling of the faro lagoon was completed ~ 4500 yr BP. An island formed that was flanked on its south side by a shallow lagoon and surrounded by a reef flat. Through several phases of land reclamation since the 1950s, the shallow lagoon was infilled and the reef flat buried with sand and rubble to form Malé Island as it is known today.
How reefs drown: A case study from the Northwest Hawaiian Islands
Authors: Toomey Michael , Sandstrom Michael , Magette Evan , Cronin Thomas
Published: December 2022

Thousands of deeply submerged seamounts are scattered across ocean basins, many capped by thick successions of reef carbonates accumulated over millions of years prior to island drowning. How conditions sustaining shallow-water reef development at these sites deteriorated is often unclear but could lend insights into the processes that put stress on modern reef communities. Here the authors examine reef drowning in the Northwest Hawaiian Islands, brought on by low rates of carbonate accretion that often occur at mid-latitude (> 30) locations. New strontium-isotope stratigraphy from shallow water carbonates sampled from a 499 m-long boring through Midway Atoll suggest limited accumulation has occurred at the site since the early-Miocene (~ 16 Ma). The offshore morphology of Midway indicates carbonate production has often been outpaced by wave erosion during the Pleistocene, shifting the island’s centre ~ 3 km to the south-east in the prevailing wave direction and increasing its circularity. Strong wave action and slow reef accretion may also explain development of extensive reef flats on Midway and nearby islands. Similar features are shared with some other carbonate islands at mid-latitudes but are not typical of Central Pacific atolls, more generally, or guyots. Abrupt sea-level rise may therefore provide a more plausible mechanism for atoll/guyot drowning in the geologic past than poor environmental conditions for carbonate accretion as has previously been invoked.

New sedimentological data of facies and diagenesis as well as chronological data including strontium (87Sr/86Sr)-isotope ratios and uranium (U)-series dating, radiocarbon (14C) accelerator mass spectrometry (AMS) dating and biostratigraphy from elevated reef terraces (makatea) in the southern Cook Islands of Mangaia, Rarotonga and Aitutaki contribute to controversial discussions regarding age and sea-level relationships of these occurrences during the Neogene and Quaternary. The oldest limestones of the uplifted makatea island of Mangaia include reef-related facies which are mid-Miocene in age, based on new Sr-isotope and biostratigraphical data. In between these older deposits and the lowest coastal reef terrace of marine isotope stage (MIS) 5e, various older Pleistocene reef-related facies were identified. Based on Sr-isotope ratios, these were deposited during earlier Pleistocene highstands (as old as 2.28 Ma). Rare reef terraces on Rarotonga belong to the Plio-Pleistocene and the late Miocene, according to 87Sr/86Sr ratios. The late Miocene age is enigmatic as it exceeds the age of subaerially exposed volcanic rocks of Rarotonga island. The fossil reef could have formed on an older submarine volcanic high that was later displaced by younger volcanism to its present position, or the Sr-age could be too old due to diagenetic resetting. The Plio-Pleistocene Rarotonga reef terraces are overlain irregularly by Holocene reef deposits that are interpreted as storm rubble. Reef terraces on Aitutaki represent evidence of a higher-than-present (up to 1 m) sea-level during the late Holocene, based on 14C AMS age data. They are very similar to elevated late Holocene reefs of adjacent French Polynesia with regard to composition, elevation and age.

Wireless sensor network (WSN) is a multi-hop self-organizing system that is composed of a large number of sensor nodes. A node is any point within a CH, which could be any point. With the energy usage nature of wireless sensors, clustering is an effectual way to address energy usage difficulties. It is the criterion by which the total price, the number of necessary cluster heads for optimal system utilization, as well as the durability of the system; as a result, it is widespread used in WSN applications. A form of optimization method, met heuristic processes, use a tradeoff of randomization and local search. The Crow New Algorithm is one of many nature-inspired meta - heuristic algorithms (CSA). Using bioinspired methods, optimize the cluster head as well as congregation node requirements. To put the suggested method in MATLAB for a 100-node network. Try comparing the current and proposed techniques for a simulation of 100 nodes based on the amount of alive nodes, the number of dead nodes, the amount of packet delivery to the base station, as well as the platform's residual energy.

Positivity in Action: Character Education through the Positivity Project
Authors: Garwood Justin D
Published: December 2022

Recently, a new program – The Positivity Project (P2; https://posproject.org/) – has been developed to address key implementation challenges for teachers. P2 is a professional development program focused on teacher’s use of project-based learning and a universal student character education curriculum that provides educators and students with tools to support socio-emotional skills through daily, 15-minute learning modules across the school year. In this article, we (a) explain the theory informing P2, (b) detail key implementation components, (c) include real-life accounts from students and teachers using P2 across K-12 and alternative settings, and (d) provide suggestions for evaluating the impact of P2 for those schools considering implementation. The P2 program is informed by positive psychology, a strengths-based approach to instruction that is well-suited to support students with disabilities. Currently, there is promising evidence of P2 effectiveness that could be classified as practice-based evidence (see https://posproject.org/). Schools wishing to explore use of P2 may wish to consider the best ways to measure the effectiveness of the program. One option is the Values in Action Inventory of Strengths for Youth, which was developed to assess the 24 character strengths from positive psychology and has been translated into multiple languages.
