Oleh karena itu tujuan penelitian deskriptif kualitatif ini adalah mendeskripsikan kesalahan-kesalahan mahasiswa dalam menyelesaikan masalah diferensial berdasarkan teori Castolan. Teori Castolan meliputi kesalahan konsep, kesalahan prosedur, dan kesalahan teknik. Penelitian dilakukan terhadap mahasiswa peserta mata kuliah matematika dasar. Data dikumpulkan dengan metode tes dan wawancara dengan instrumen pendukung berupa tiga soal tes masalah deferensial dan pedoman wawancara. Data dianalisis dengan tahapan reduksi data, penyajian data, dan penarikan simpulan. Hasil penelitian ditemukan bahwa berdasarkan teori Castolan sebagian besar mahasiswa melakukan kesalahan strategi dan kesalahan hitung dan sebagian kecil melakukan kesalahan konsep. Kesalahan konsep terjadi saat mahasiswa salah menentukan rumus. Kesalahan strategi terjadi saat mahasiswa salah menggunakan rumus, tidak mampu menyelesaikan sampai bentuk yang sederhana serta ada data yang hilang. Sedangkan kesalahan hitung sebagian besar karena salah menulis atau menghitung. Adapun penyebab terjadinya kesalan tersebut karena kurang memahami konsep, belum terbiasa menyelesaikan soal yang membutuhkan memiliki keterampilan berpikir tingkat tinggi, serta kurang teliti Dengan mengetahui kesalahan serta penyebabnya dapat menumbuhkembangkan kreativitas dosen untuk mengatasi kesulitan yang dihadapi mahasiswa.
Differential material is widely used as a prerequisite for other materials and other courses. But not a few students who find it difficult to learn it. Therefore, the purpose of this qualitative descriptive research is to describe students’ mistakes in solving differential problems based on the Castor theory. Castor’s theory includes conceptual errors, procedural errors, and technical errors. The research was conducted on students participating in basic mathematics courses. Data was collected by test and interview methods. The supporting instruments used were three differential problem tests and an interview guide. The student answers were then analyzed to see which represented the most errors. Test the validity of the data using technical triangulation. Data were analyzed with the stages of data reduction, data presentation, and drawing conclusions. The results of the study found that most students made procedural and technical errors, and a few made conceptual errors. Conceptual errors occur when students incorrectly determine the formula. Strategy errors occur when students use the wrong formula, are unable to complete a simple form, and there is missing data. While the technical errors are mostly due to wrong writing or counting. The cause of this errors is because they do not understand the concept, are not used to solving problems that require high-level thinking skills and are not thorough.

Crianzas y cuidados: mujeres de origen africano en las ciudades de México y Querétaro, siglo XVIII
Authors: Velázquez Gutiérrez María Elisa 
Published: June 2024

Este artículo tiene el objetivo de reflexionar sobre dos actividades desempeñadas por mujeres de origen africano en la Nueva España: la crianza de los niños y el cuidado de enfermos o ancianos en las ciudades de México y Querétaro en el siglo XVIII. Se analiza la importancia de estas tareas, como parte de los trabajos forzados y obligados que realizaban, pero también como medios para establecer relaciones y vínculos afectivos, y en ocasiones la libertad y mejores condiciones de vida. Se hace hincapié en la importancia de la convivencia y el intercambio entre diversos grupos y en los prejuicios, que, sobre todo en el siglo XVIII, se desarrollaron sobre las costumbres de “negras y mulatas.” El análisis de estos casos se basa en los conceptos de reproducción y recreación cultural de los antropólogos Mintz y Price, así como de estudios sobre la importancia de los cuidados en la vida cotidiana de tradición antropológica.

Some pregnant women (46.7%) have negative behavior to overcome emesis gravidarum, which means they have not been able to overcome the emesis that occurs to them. Untreated emesis gravidarum will progress to hyperemesis gravidarum which can endanger maternal health and fetal development. One of the most important things in person's healthy behavior is self-efficacy. Self-efficacy can be formed through verbal persuasion to convince individuals that they are capable of achieving certain results. The video â€œsahabat ibu hamilâ€ is an educational media for pregnant women that applies the principles of verbal persuasion in an effort to strengthen the confidence of pregnant women to be able to implement healthy behavior to overcome emesis gravidarum.

Ocupaciones de vivienda, informalidad y Estado en Patagonia Austral
Authors: Gonzalez Noemi Raquel , Destito Gastón 
Published: June 2024

Las ocupaciones de las obras paralizadas del Programa Federal de Construcción de Viviendas-Techo Digno en Caleta Olivia en 2015 nos permitirán echar luz sobre la informalidad como proceso social y político en el que el Estado no es mero administrador, sino que, a través de instituciones, funcionarios y funcionarias promueve e interviene en él de manera activa. Desde un enfoque etnográfico y una perspectiva relacional mostramos cómo las ocupaciones de vivienda se inscriben en procesos colectivos de distintas escalas, atravesados por el contexto electoral que removió la arena política local y modificó el horizonte de lo posible, lo cual reconfiguró la crisis habitacional. Proponemos una perspectiva analítica que estudia las ocupaciones dentro de un complejo proceso social y analizamos cómo las políticas de cercanía influyen en los procesos de adjudicación y ocupación de viviendas, así como en los efectos que ello produce a nivel social.
A Comparative Study of Global Accounting and Indian Accounting
Authors: Archunan K , Ramaiyan C 
Published: June 2024

Accounting is a tool to quantify all economic and business transactions in terms of money. The economic and non-economic transactions are measured and compared from year to year and country to country with the help of accounting only. Hence, accounting is a backbone of evidence to identify the strength and weakness of any sector of the country. The accounting systems vary from country to country depending upon the nature of the business. The ancient accounting system has a narrow concept which has been followed within a country. Later in the ancient international trade, business tractions were based on the barter system. The traders followed informal accounting records for their business transactions, before the industrial revolution. Due to the industrial revolution (1760) there was mass production in the textile industries, steamindustries, and iron industries. The huge volume of production led to changes in the field of accounting. The spread of the industrial revolution across Europe, hence it requires a common accounting system among the European countries. The expansion of the volume of economic and business transactions gives the necessity of a globally accepted accounting system. Moreover, in the international trade, all countries around the world are involved in both imports and exports. Hence, the international accounting system is required to know the accuracy of global business transaction. India has its own accounting system which is based on the Indian Companies Act, 1956, later the Indian Companies Act, amended, 2013. The Indian Accounting Standard is applicable only to India, which is framed for Indian companies located in India. If any IndianCompanies located outside India have to follow the International Accounting standards.
