To preserve the environment, it is necessary to innovate the use of plastic waste in the manufacture of building materials. Innovations that can be applied to this brick mix are such as adding inorganic materials, one of which is by adding PET plastic as a substitute for sand to the brick mix to innovate and know the strength of the bricks. the authors added a mixture of PET plastics with plastic percentages of 0%, 20%, 25%, and 30%. The calculation of brick mix planning uses reference SNI-03-0349-1989 with a compressive strength plan of 10 MPa. Compressive strength tests have various compressive strength values, namely variations of 0%, 20%, 25% and 30% obtaining compressive strength values of 7.92 MPa, 7.24 MPa, 7.52 MPa, and 7.24 MPa. . The addition of plastic as a substitute for sand in too many bricks proved ineffective against bricks. This means that the use of too much plastic can cause mortar and plastic to not be able to lock each other.

Concrete is a construction material that is often used in building construction. Concrete is a mixture consisting of coarse aggregate and fine aggregate mixed with water and cement as a binder and filler, and additives are often added. Bagasse fiber has the criteria needed to be used as an added material for strengthening concrete. The variations of bagasse fiber used were 0%, 2.5%, 5%, 7.5% and 10%. The results showed a decrease in the slump value, this was due to the higher variation of bagasse substituted for the weight of cement with the same FAS value, which would reduce the workability of the concrete. The compressive strength of concrete with variations of sugarcane fiber decreased. The highest compressive strength value is found at 0% variation, namely 20.93 MPa, this is due to the greater percentage of bagasse fiber mixture, the concrete that should be filled with aggregate is filled with sugarcane fiber, causing the compressive strength of the concrete to decrease.

This study aims to design Arduino-based scales for weight, height, body mass index. Height and weight measuring device is a measuring tool that functions to measure the height and weight of a person's body. To measure height and weight in general, it is still done separately (separately) in this case the measurements of height and weight are carried out using different tools. By increasing the pace of technological advances, especially in the health sector, according to the author's observations, the height and weight measuring devices are still manual, it's time to increase their function, in this case, it is necessary to increase the function of the tool, especially those related to the field of electronics. The results of measuring weight using CAMRY brand scales with Karya Nesa scales, the average error rate is 0.037 (still within the tolerance threshold), while the results of measuring height are in accordance with the actual. From the results of the Body Mass Index (BMI) analysis with the results of the Body Mass Index (BMI) measurement by Nesa, it is correct and valid (valid). The error rate of weight or scales is relatively small, the accuracy of the scales is very good. The error rate is declared large, if the error is above 5% or greater than 0.05. Based on the results obtained, it is suggested that the scales need to be made precise (not rocking), this can be harmful to the patient and needs to be developed by adding sounds such as: weight, height and BMI results

Practical Tools for Practitioners: Unravelling Power Dynamics as a Prelude to Preventing Violence Against Women and Children
Authors: McAlpine Kate
Published: January 2024

This paper explores how to employ effective, community-engaged strategies to understand and address the underlying power asymmetries that fuel violence against women and children. Utilising Participatory Action Research and underpinned by Integral Activist Epistemology, the action research adopts a novel approach combining Theory U and Powercube frameworks to facilitate a comprehensive understanding and transformation of these power relations in Shinyanga district, Tanzania.

The paper describes the journey of engaging the community in identifying and challenging the unwritten rules that perpetuate violence. Key to this process is the recognition of violence as a manifestation of deeply ingrained patriarchal power structures, which are sustained through coercion and social exclusion, yet paradoxically fragile due to the pain these norms inflict on the whole community, including men. This understanding leads to the development of practical, community-led interventions, or 'prototypes', aimed at reshaping these dynamics.

Key messages from the action research highlight the critical role of local context in shaping interventions, the importance of reframing existing cultural practices so that they are more inclusive, and the necessity for long-term commitment from development actors for sustainable change. The implications extend beyond Shinyanga, offering insights for practitioners globally. This paper contributes to the academic discourse on violence prevention but also serves as a practical guide, providing tools and strategies for practitioners working towards creating safer, more inclusive communities.

Published: January 2024

Atmospheric methane concentrations rose rapidly over the past decade and surged in 2020-2022 but the causes are unclear. We find from inverse analysis of GOSAT satellite observations that global methane emissions increased from 500 to 550 Tg a-1 from 2010 to 2019 and surged to 570-590 Tg a-1 in 2020-2022. Concentrations of tropospheric OH (the main methane sink) show no long-term trend over 2010-2019, but a decrease over 2020-2022 that explains 28% of the methane surge. The methane emission increase over 2010-2022 is mainly from the wet tropics with dominant anthropogenic and wetland contributions from Africa (43% of the global emission increase), South America (18%), Equatorial Asia (18%), and India and Pakistan (12%). Emissions from the US and Russia decreased slightly over the period. The 2020-2022 emission surge is consistent with the terrestrial water storage increase due to tropical inundation in Africa and Equatorial Asia associated with La Niña conditions.

Published: January 2024

Climate change is currently one of humanity’s greatest threats. To help scholars understand the psychology of climate change, we conducted an online quasi-experimental survey on 59,508 participants from 63 countries (collected between July 2022 and July 2023). In a between-subjects design, we tested 11 interventions designed to promote climate change mitigation across four outcomes: climate change belief, support for climate policies, willingness to share information on social media, and performance on an effortful pro-environmental behavioural task. Participants also reported their demographic information (e.g., age, gender) and several other independent variables (e.g., political orientation, perceptions about the scientific consensus). In the no-intervention control group, we also measured important additional variables, such as environmentalist identity and trust in climate science. We report the collaboration procedure, study design, raw and cleaned data, all survey materials, relevant analysis scripts, and data visualisations. This dataset can be used to further the understanding of psychological, demographic, and national-level factors related to individual-level climate action and how these differ across countries.
A Renewal of Dyadic Structural Equation Modeling with Latent Variables: Clarifications, Methodological Advantages and Trends, Reflections, and New Directions

Published: January 2024

Researchers interested in the quantitative analysis of data from dyads must select a preferred statistical framework. In this review, we focus on one option that has seen relatively modest adoption: dyadic structural equation modeling with latent variables. We begin by distinguishing dyadic SEM from alternate, neighboring, and hybridized frameworks, before sharing our view on the unique—and in our opinion, considerable—value-proposition of the dyadic SEM framework. We then provide some preliminary evidence that dyadic SEM is subordinated in terms of adoption rates versus its competitors, before offering a contextual analysis of why that may have come to be the case. Finally, we conclude with a discussion of future possibilities, some near and accessible and others farther away and more technical, that researchers in the field might pursue (and benefit from) with the help of dyadic SEM with latent variables.

Published: January 2024

Background: Military Servicemembers and Veterans are at elevated risk for suicide, but rarely self-identify to their leaders or clinicians regarding their experience of suicidal thoughts. We developed an algorithm to identify suicidal Servicemembers and Veterans on a military-specific social media platform. Methods: Publicly-shared social media posts (n = 8449) from a military-specific social media platform were reviewed and labeled by our team for the presence/absence of suicidal thoughts and behaviors and used to train several machine learning models to identify such posts. Results: The best performing model was a deep learning (RoBERTa) model that incorporated post text and metadata and detected the presence of suicidal posts with relatively high sensitivity (.85), specificity (.96), precision (.64), F1 score (.73), and an area under the precision-recall curve of .84. Compared to non-suicidal posts, suicidal posts were more likely to contain explicit mentions of suicide, descriptions of risk factors (e.g., depression, PTSD) and help-seeking, and first-person singular pronouns.Conclusions: Our results demonstrate the feasibility and potential promise of using social media posts to identify at-risk Servicemembers and Veterans. Future work will use this approach to deliver targeted interventions to social media users at risk for suicide.

Springs are the primary source of water for the people inhabiting in the hills and mountain regions of Nepal. Climate variability, climate change, land use change and management factors together with various human activities including haphazard infrastructure development like urbanization and road construction over the recharge area are responsible for drying up of springs in the hills and mountains, especially in the mid-hill region of Nepal. This study attempts to identify the potential recharge zones of the springs within the four catchments viz. Banlekh and Shikharpur of Baitadi and Doti districts, respectively in far-western Nepal, and the Khaste and Begnas of Kaski district in western Nepal through hydrogeological mapping. Hydrogeological Conceptual Model was adopted while identifying the potential recharge areas. We measured the orientation of the rock outcrops, their types, and discontinuities found around the possible recharge areas. We prepared a conceptual hydro-geological layout of the spring-sheds based on the collected data, and delineated the potential recharge areas. We found the potential recharge zone of the Banlekh Springs at hill slopes and bedding plane within the catchment. However, the recharge zone of the Shikharpur Springs was found on the top and beyond the catchment due to the presence of a number of sinkholes. Moreover, the recharge zone of the Thulopadhero Spring was found to be controlled by the orientation of the rocks and fractures found in the unconsolidated sediments within the catchment and beyond the ridge of the escarpment. The rock orientation within the Falekund-Saunepani-Lapsibot Catchment suggests that the potential recharge zone of the springs consists of unconsolidated sediments. The identified potential recharge areas, the observed rainfall, and the discharge data on springs indicated that the recharge areas were more influenced by the local geology.

Korupsi merupakan kejahatan dengan kategori extra ordinary crimes yaitu kejahatan luar biasa. Salah satu jenis tindak pidana korupsi adalah gratifikasi. Pada perkembangan saat ini gratifikasi bukan pemberian barang mewah atau uang, fasilitas penginapan, pinjaman tanpa bunga dan sebagainya namun saat ini telah disajikan dengan jasa pelayanan seksual yang digunakan sebagai gratifikasi pelayanan seksual terhadap penyelenggara negara. Pengaturan gratifikasi seksual di Indonesia pada Pasal 12B Ayat 1 Undang-Undang Nomor 20 Tahun 2001 tentang Pemberantasan Tindak Pidana Korupsi pada bagian penjelasan belum secara tegas mengatur sanksi kepada para pihak gratifikasi seksual. Penelitian ini berfokus untuk mengetahui perbandingan pengaturan gratifikasi seksual di Indonesia dan India. Metode yang digunakan dalam penelitian ini yaitu yuridis normatif menggunakan pendekatan perundang-undangan, konseptual, dan perbandingan. Penelitian ini menghasilkan kesimpulan bahwa pengaturan gratifikasi seksual di India lebih tegas dibandingkan dengan pengaturan gratifikasi seksual di Indonesia, karena India telah berani memasukkan gratifikasi seksual kedalam undang-undang tindak pidana korupsinya.

Penelitian ini bertujuan untuk mengetahui dan menganalisis upaya akselerasi energi bersih dalam cengkraman oligarki. Penelitian ini adalah penelitian studi literatur atau kepustakaan dengan metode systematic literature review (SLR). Hasil dari penelitian ini menunjukkan bahwa terdapat fenomena institutional hypocrisy di dalam upaya akselerasi energi bersih yang di Indonesia. Fenomena ini dibuktikan dengan pemerintah yang berkomitmen terhadap pengembangan energi terbarukan, namun pemerintah masih memberikan izin kepada perusahaan untuk membangun dan mengoperasikan PLTU dalam skala besar. Kesimpulan dari penelitian ini memberikan solusi untuk akselerasi energi dalam cengkraman oligarki dengan dialihkannya anggaran subsidi kendaraan berbasis listrik untuk energi terbarukan. Langkah ini diharapkan dapat memberikan kontribusi positif terhadap mitigasi perubahan iklim dan peregulasian yang dapat mempersempit ruang monopoli oligarki di dalam sektor SDA.
