Use of Social Media, Satisfaction with Body Image, and the Risk of Manifesting Eating Disorders
Authors: Arjona Ángeles , Monserrat Montserrat , Checa Juan Carlos
Published: February 2024

Eating disorders in adolescents are an increasingly important issue nowadays. Although they have been shown to be a pathology with multifactorial causes, the objective of our study is to determine the degree of influence that body dissatisfaction and the use of social media (time and type) might have on the risk of manifesting eating disorders. To perform this, the Sick Control One Fat Food scale was used as part of a randomized survey carried out among 12 schools in Almería (Spain). The sample consisted of 605 students in Compulsory Secondary Education between the ages of 12 and 17 years (M = 14.27; SD = 1.44), 48.42% female and 51.52% male. Cross-tabulation tables were constructed to observe the relationship of sex and age with the risk of manifesting EDs, and, subsequently, a two-factor ANOVA was performed using the risk of suffering from an eating disorder as a dependent variable. The results show that 29.3% of the respondents express an elevated risk of suffering from an eating disorder. There are no significant differences regarding sex, but there are differences regarding age. It was also observed that dissatisfaction with body image is a significant risk factor, but not the time that young people spend on social media. Furthermore, the type of content displayed on social media has a significant influence, both independently and together with body dissatisfaction. The main conclusion highlighted in this study relates to the importance of self-perceived body image (satisfaction and dissatisfaction) and its relationship with the type of content seen on social media. For this reason, it is essential to work on self-esteem at an early age as well as learn to value others and oneself beyond just the physical.

Published: February 2024

With the rapid advancements in Information and Communication Technologies (ICT) and the widespread enthusiasm of both theoreticians and practitioners, the broader transition to Industry 4.0 (I4.0) in major industries appears imminent. This empirical study analyzes business data from 1140 automotive companies operating in Europe, utilizing various business intelligence platforms and employing decision tree analytics to establish connections between enablers, drivers, company size, and financial resources. The goal is to identify persistent barriers hindering the rational transition to Industry 4.0. The findings reveal an uneven transformation within the industry nexus. While larger companies possess the financial means to allocate collective intelligence, technical resources, and drive necessary for fulfilling I4.0 requirements, smaller members of the nexus lag behind despite their enthusiasm and intent. This imbalanced evolution poses a threat to the comprehensive transformation required for realizing all the benefits of Industry 4.0 within the sector. The primary discovery indicates that small to medium-sized enterprises do not exhibit the same rates of Industry 4.0 adoption, a lag highly correlated with their available financial and human resources for digital transition. The decision tree proposed in this study offers guidelines for achieving an Industry 4.0-compliant nexus. Given its diversity and substantial global impact, the case study from the automotive industry proves intriguing and may later be generalized to other sectors. The study’s outcome could empower engineering managers and researchers to implement, execute, and assess the impact of digital strategies based on the financial capabilities of industrial institutions.

Authors: Caselli Barbara , Pedilarco Giulia , Pellicelli Gloria , Rossetti Silvia , Zazzi Michele
Published: February 2024

The paper adds to the debate on urban transformation, which plays a significant role in improving quality of urban life and liveability of public spaces, as also stated in UN Sustainable Development Goal No. 11. The research aims to test a methodology for identifying an abacus of urban regeneration interventions to enhance attractive and critical nodes through accessibility and inclusivity. The quality of the system of connections between polarities, the promotion of active mobility, zero soil consumption and the renaturalisation of urban spaces are fundamental criteria to define urban regeneration solutions. The proposed approach develops on two levels: a GIS-based spatial analysis of urban data and a participatory process. The innovative planning process is tested on the San Leonardo neighbourhood in the Municipality of Parma, Italy, which allows us to verify the potentials and limitations of the procedure, identifying future work perspectives. Moreover, the application allows us to check the replicability in other urban contexts, possibly envisaging other applications to more case studies. Our results consist of the identification of the vocations and the critical aspects of nodes and axes to regenerate urban space in medium-sized and large cities’ suburbs.

Published: February 2024

The current study examined the psychological mechanism that underlies the relationship between parents’ response style and children’s subjective well-being and its boundary conditions, the mediating role of the parent–child relationship, and the moderating role of friendship quality. Using the Parents’ Responses to Children’s Performance Scale, the Buchanan Scale of Closeness to Parents, the Friendship Quality Questionnaire, and the Campbell Index of Well-being, our study investigated 686 pupils who were randomly selected from three public schools in central China. Employing Mplus 8.3 for pathway analysis, we found the following results: Failure-oriented responses negatively predict children’s subjective well-being (β = −0.16, p < 0.001), while success-oriented responses positively predict children’s subjective well-being (β = 0.13, p < 0.01). Both failure-oriented (ab = 0.18, SE = 0.03, 95% CI = [0.13, 0.25]) and success-oriented responses (ab = −0.10, SE = 0.02, 95% CI = [−0.14, −0.06]) predict children’s subjective well-being through the mediating effect of the parent–child relationship. Friendship quality has a moderating effect on the mediating path (β = −0.09, p < 0.05), such that when friendship quality is lower, the parent–child relationship has a higher mediating effect between the parents’ responses and children’s subjective well-being. This study offers empirical evidence that parents’ responses to children’s performance significantly contribute to children’s subjective well-being. Moreover, it offers actionable insights for enhancing children’s subjective well-being. The enhancement could be achieved by fostering positive parent–child relationships and enhancing the quality of children’s friendships, thereby positively impacting their well-being.

Published: February 2024

The protection of air from pollution is one of the basic principles of sustainable development, and this article analyzes the joint impact of various types of agricultural production and traffic on nitrogen oxide (NOx) emissions. The goal of this research is the development of a new methodology for assessing the combined impact of different types of agricultural production, traffic load, and traffic flow structure on the emission of nitrogen oxides. For the analysis of the joint impact of traffic and agricultural production, a new impact assessment methodology was developed, which is based on two selected impact prediction models. The following two models were used to predict the impact: the BioGrace model and the microsimulation model VISSIM. The developed methodology was applied to a case study in real field conditions. The results showed that the difference in the emission of NOx gases, depending on the type of agricultural production, indicates a reduction in NOx emissions in the walnut–winter-wheat system by 30%, compared to the production of winter wheat in an open field. The statistical analysis showed that there is no statistically significant difference between NOx emissions for different vehicle arrival scenarios for the same traffic load. The results of the joint impact show that the lowest NOx emission was found in walnut orchards and counted traffic. In this example, the difference between the one-hour emission load of three different agricultural types of production and traffic is not large; however, in the cumulative load, it can lead to significant differences. Emphasizing the importance of adopting new agricultural practices and the impact of traffic and the share of freight and heavy goods vehicles in agricultural production, we position them as a proactive and sustainable response to the critical ecological and agricultural challenges highlighted in European and Croatian policy.

Published: February 2024

Delays and cost overruns in turnkey projects can lead to significant economic losses, disputes and even project abandonment. These facts negatively impact the environmental, social and governance (ESG) policies of companies involved in the project. In this paper, a bibliographic review was conducted to identify the leading causes of delays and cost overruns in turnkey industrial projects in the refining, gas and conventional electricity generation (RGE) sector and propose good practices to avoid or mitigate them. We identified 893 causes of delays and cost overruns and 147 mitigation measures. The causes and mitigation measures were grouped into eight categories based on the execution phases of an RGE project. A critical analysis was carried out to avoid duplication, and the result was evaluated by experts in turnkey project management, reducing the causes and mitigation measures to a final set of 103 and 49, respectively. The construction category showed the most significant influence on project delays and cost overruns, and this, together with the preliminary phase and project management categories, contributed to 60% of the identified causes. The findings of this study can help project managers improve the profitability of turnkey industrial projects, promoting innovation and sustainability within companies and society.

Authors: Ávila Urdaneta Juan Gerardo , Fuentes Águila Marily Rafaela
Published: February 2024

La transgresión al principio de igualdad en las normas sobre violencia contra la mujer y miembros del núcleo familiar constituye uno de los temas más controvertidos en la práctica judicial. Los abogados ecuatorianos han criticado los procedimientos para la sustanciación de los hechos de violencia intrafamiliar, toda vez que, en el afán de erradicar la violencia de género contra las mujeres, se ha asumido un tratamiento jurídico desigual. Si bien es necesario sancionar por el delito cometido y ofrecer una respuesta ante los abusos contra las mujeres y la familia, cuando se comparan estas infracciones con un secuestro, homicidio o asesinato, es evidente que, en la realidad, se les priva a los supuestos infractores de derechos y garantías como la suspensión de la pena o los beneficios del régimen progresivo cuando existen hechos que no presentan la gravedad que se les atribuye. A través de una metodología cualitativa que utiliza el método de análisis documental, se tuvo como objetivo someter a crítica y reflexión el procedimiento de juzgamiento por delitos y contravenciones contra la mujer y miembros del grupo familiar, para lo cual se consultaron autores nacionales y extranjeros y, la legislación interna y de derecho internacional. Se denuncia con toda la claridad, la falta de igualdad procesal y sustantiva en contra de las personas procesadas por este tipo de infracciones en Ecuador.

Authors: Crouzet-Pavan Elisabeth
Published: February 2024

The years after the fall of Constantinople witnessed a period of intensive diplomatic activity, with Christian powers trying to form an alliance against the Ottomans, including one with the new dominant power in Persia, Uzun Hasan’s White Sheep horde. After a brief geopolitical survey of the final decades of the 15th century, this article analyses Venice’s political game during this moment. This example of intensive diplomatic contacts between the Christian world and the Persian Orient reveals a weft of older relations, made of economic exchanges and wellestablished connections. In this context, during the last decades of the 15th century there were points of connection between the great medieval political and economic areas. The court of the Khan of the White Sheep Empire, where the Venetians could encounter Indian ambassadors carrying letters of credentials and meet Turkish and Tartar envoys was one of these places where the worlds were connected.

Consumption of petroleum products continues to grow steadily. In 2020, oil consumption numbers surpassed exploration's, indicating a possible market imbalance. That said, the demand for new oil reserves becomes essential. Prospecting techniques for these commodities are used to have greater accuracy before drilling a well. Different Geological, Geophysical, and Geochemical methods are applied with different principles in their search, with Seismic being the most widely used technique. Sniffers have gained ground among geochemical methods, and new technologies are emerging. Despite many methods, none is conclusive and should be used in conjunction with others, whether in the prospecting area or for leak monitoring.
Energy sources as a function of electric vehicle emission: The case of Bosnia and Herzegovina
Authors: šehović Jasmin , Bibić Dževad
Published: February 2024

This paper deals with the analysis of challenges and perspectives of the transition to electric vehicles as a sustainable solution for the transport sector in the context of global energy challenges and the need to reduce negative environmental impacts. With an emphasis on the energy situation in Bosnia and Herzegovina, the paper explores the possibilities of switching to electric vehicles (EVs) and analyses the effects of energy sources on CO2 emissions. The paper highlights the motivation to switch to EVs, driven by the need to reduce greenhouse gas emissions and rely on renewable energy sources. After analysing relevant studies, it is concluded that smaller and lighter electric vehicles have lower CO2 emissions and that the participation of renewable sources in electricity production reduces these emissions. The conducted analysis of the vehicle fleet specifies that the CO2 emissions of electric vehicles are not zero and that they depend on the source of electricity. Furthermore, other factors, such as the production of batteries, also play an important role in the overall environmental impact. Although the motivation to switch to electric vehicles is emphasized to reduce greenhouse gas emissions and use renewable energy sources, it has been shown that the CO2 emissions of electric vehicles (EVs) are not zero and significantly depend on the energy sources.
Calculations performed on the vehicle fleet of the Federation of Bosnia and Herzegovina for the year 2021, using Copert as the tool, showed that vehicles driven by fossil fuels emit about 1.6 million tonnes of CO2. In comparison, if all vehicles were replaced with electrical ones, the CO2 emissions would be about 1.15 million tonnes. As for the required electricity to power EVs, it is calculated that the required amount would be about 1,539 GWh per year.
This paper acknowledges the presence of emissions associated with battery production, storage, and disposal, as well as vehicles themselves. However, it does not delve into this issue in detail. Future research will aim to address this matter more thoroughly.

Mechanism of photoresponsivity reduction in BaSi2 epitaxial films by post-annealing at moderate temperatures
Authors: Aonuki Sho , Haku Yurika , Narita Shunsuke , Takayanagi Kaori , Iwai Ai , Toko Kaoru , Suemasu Takashi
Published: February 2024

Photoresponsivity is an important measure for applications as light absorbing layers because it is proportional to carrier lifetime. Previous studies have shown that the photoresponsivity of undoped BaSi2 films increases by more than 10 times by post-annealing (PA) at 1000 °C, but decreases by moderate-temperature PA. Such BaSi2 films are compressively strained in the normal direction, regardless of whether they are undoped or As-doped BaSi2 films and show a distinct photoluminescence around 0.85 eV at 8 K, indicating the formation of a new localized state. These provide a clue to the annealing conditions that lead to photoresponsivity reduction.

Teknologi merupakan salah satu pengaruh dalam perkembangan dunia pendidikan. Hal tersebut dibuktikan dengan tuntutan kurikulum merdeka yang digunakan saat ini, yaitu menuntut guru untuk mengikuti perkembangan zaman, dengan cara menerapkan teknologi sebagai salah satu media pembelajaran. Dari tuntutan kurikulum tersebut, ditemukan beberapa masalah dari kenyataan yang ada, dimana guru masih menggunakan media papan tulis dan buku cetak, sehingga media yang digunakan guru masih sederhana dan monoton. Maka dari itu, media pembelajaran interaktif matematika berbasis ICT merupakan sebuah solusi untuk membantu guru serta peserta didik kelas X. Metode Research and Development (R&D) versi Hannafin and Peck digunakan dalam penelitian ini, dengan melakukan 3 tahapan, diantaranya menganalisis kebutuhan, mendesain media, kemudian mengembangkan dan mengimplementasikan, dimana disetiap tahapannya terdapat evaluasi dan revisi. Uji produk dilakukan melalui instrumen angket validitas, angket praktikalitas, dan angket efektivitas, dan memperoleh hasil nilai validitas 0,88 dalam kategori valid, nilai kepraktisan 0,91 dalam kategori sangat praktis, dan nilai keefektifan 0,87 dalam kategori sangat efektif. Dari hasil yang diperoleh, disimpulkan bahwa media pembelajaran interaktif matematika berbasis ICT yang dihasilkan sudah valid untuk digunakan oleh guru dan peserta didik kelas X sebagai media pembelajaran matematika yang memberi kepraktisan dan keefektifan dalam belajar.

Gizi adalah makanan dan zat-zat penting yang dibutuhkan tubuh untuk tetap sehat dan kuat. Terutama bagi balita dan anak-anak, gizi sangat penting untuk pertumbuhan fisik yang baik dan mencegah berbagai penyakit. Di Indonesia, masalah gizi buruk mengancam perkembangan balita, sehingga posyandu hadir untuk memonitor gizi balita dan mencegah masalah kesehatan yang tidak diinginkan. Penelitian ini bertujuan untuk membantu pengelompokkan data balita guna mempermudah atau mempercepat pengelompokkan dari data-data balita yang jumlahnya banyak. Dengan menggunakan metode algoritma K-Means peneliti berhasil mendapatkan sebuah data balita dimana data tersebut sudah terkelompokkan dari berbagai gizi dan di uji dengan aplikasi Rapidminer. Peneliti mendapatkan hasil yaitu klaster 1 terdapat 19 data, lalu klaster 2 terdapat 24 data, dan terakhir klaster 3 terdapat 37 data, lalu dilakukan sebuah pengujian pada aplikasi rapidminer dan mendapatkan hasil pengujian yang sama,  yaitu klaster 1 terdapat 19 data, lalu klaster 2 terdapat 24 data, dan terakhir klaster 3 terdapat 37 data dari total 80 data balita Posyandu Melati VII. Dengan begitu K-Means dapat digunakan sebagai mempermudah pengelompokkan pada gizi balita Posyandu Melati VII dalam skala jumlah yang banyak.

Algoritma apriori adalah metode penambangan data untuk mengidentifikasi ketentuan asosiasi antar barang. Algoritma apriori mempunyai dua standarisai yaitu support dan confidence. Support (nilai penyangga) persentase gabungan item, confidence (nilai ketentuan) keterikatan antar objek hubungan asosiasi. Metode apriori sudah pernah dilakukan untuk kasus penelitian pola kombinasi penjualan transaksi minimarket namun belum pernah dipakai untuk kasus layanan homecare. Saat ini data mining  banyak digunakan diberbagai sektor bisnis pada bidang industry, seperti perusahaan Salam Homecare yaitu layanan kesehatan di rumah yang saat ini beroperasi di Bandung sejak tahun 2021. Metode apriori diimplementasikan dengan tahapan pra proses seleksi data atribut, kemudian data dicari nilai support pada iterasi 1, 2, 3 dan seterusnya lalu mencari nilai confidence untuk menentukan probabilitas pola kombinasi itemset. Hasil penelitian menunjukkan Transaksi layanan homecare yang mempunya nilai support tertinggi yaitu Swab Pcr Reguler sebesar 0,367. Transaksi layanan homecare yang mempunya nilai support terendah yaitu Perawatan Luka dan Swab Pcr Sameday sebesar 0,033 Aturan asosiasi dari kombinasi 2 itemset yang memenuhi minimum confidence 0,05 yaitu Infus Vitamin Booster & Vitamin C dan Visit Dokter sebesar 0,067 sehingga jika menggunakan layanan Infus Vitamin Booster & Vitamin C maka menggunakan juga layanan Visit Dokter.

Dataset di dapatkan dengan cara crawling data pada twitter setelah dataset dikumpulkan, kemudian dilakukan preprocessing untuk mengoptimalkan pengolahan data. Preprocessing terdiri dari empat tahap, yang mencakup, case folding, tokenizing, filtering dan stemming. Pembobotan kata memberikan nilai pada kata-kata yang ada di dokumen. berbeda-beda tergantung pada metode yang digunakan. Sesuai dengan algoritma yang digunakan pada penelitian ini menggunakan algoritma pembobotan kata TF-IDF dan TF-RF. Pengujiannya akan dilakukan dengan menggunakan metode klasifikasi naïve Bayes dan analisis perbandingannya dengan confussion matrix. Dengan dilakukan beberapa eksperimen 80:20 memberikan tingkat akurasi terbaik dari dua eksperimen lainnya dengan hasil akurasi TF-IDF naïve bayes 73% dan TF-RF naïve 72%. Sehingga dari kedua metode pembobotan tersebut dapat disimpulkan TF-IDF naïve bayes lebih baik hasil akurasi dibandingkan hasil TF-RF naïve bayes.
