    Agglomerative Clustering is one of data mining methods to get a cluster in form of trees. In order to achieve these objectives, we used two agglomerative methods such as Single Linkage and Complete Linkage. Searching for nearest items to be clustered into one cluster also needs a similarity distance to be measured. We used Euclidean Distance and Cosine Similarity for measuring similarity distance between two points. The factors that promote high levels of accuracy depend on the pre-proceeding stage for clustering process and also affect the results obtained. Therefore, we conducted research through several stages: pre-processing such as ETL, normalization, and pivoting. The ETL process consisted of removing outliers using IQR method, data-cleaning and data-filtering processes. For normalization, we used Min-Max and Altman Z-Score methods to get the best normal value. The results of this research demonstrate that the highest accuracy occurs when using the Complete Linkage with Min-Max and the Euclidean method with the average purity of 0.4. The significant difference is observed when using the Z-Score and Cosine Similarity methods; the average purity is around 0.11. Besides, we found that the system also could not predict the customers’ preferences in buying goods for the next period. Another result in the research is that transactional data in a company are not good enough to be clusterized

    De vínculos, subjetividades y malestares contemporáneos

    Este libro es una obra colectiva conformada por psicoanalistas argentinos que provienen de diversos campos del psicoanálisis que se dispusieron a poner en diálogo esa diversidad para establecer cruces, confrontaciones y enriquecimientos respecto de los tintes de época que caracterizan los modos de producción de las subjetividades y los malestares y sufrimientos que se ponen de manifiesto. Las y los autores establecen consideraciones respecto del entramado complejo entre lo intrasubjetivo, intersubjetivo y transubjetivo considerando que somos sujetos del vínculo y que el vínculo nos precede. Cada capítulo es recorrido por interrogantes y es posible establecer lecturas cruzadas entre ellos generando chispazos que despiertan al lector. Gran parte de esta obra fue escrita en el tiempo de inicio de la pandemia en 2020 de modo tal que cada capítulo revisiona la teoría a la luz de la actualidad de los hechos transitando un tiempo de incertidumbre y elaboración. Algunos interrogantes que plantea el libro son: ¿Es posible pensar un malestar estructural en la cultura? ¿De qué modo incide el desamparo social en la constitución subjetiva? ¿Cuánta diferencia puede tolerar un vínculo de pareja? ¿Por qué las parentalidades disidentes son exigidas a dar pruebas de su legitimidad? ¿Cuáles son las variaciones en las relaciones de poder entre varones y mujeres? ¿Qué ha sucedido con la autoridad parental en estos tiempos contemporáneos y cuál es el efecto de los cambios en los modos de ejercicio de la autoridad parental? ¿De qué manera la hipermodernidad y sus mandatos de época se ponen de manifiesto en nuevas configuraciones psicopatológicas? ¿La virtualidad y los soportes tecnológicos qué clase de temporalidad proponen y cómo ello impacta en la constitución psíquica? Cada uno de estos interrogantes pone en tensión la trama tejida entre los vínculos, las subjetividades y el malestardesde puntos de vista heterogéneos. Cada artículo explora postulados del psicoanálisis clásico en alternancia con producciones contemporáneas enlazando la clínica y los discursos de época

    Microsatellite‐based analysis reveals Aedes aegypti populations in the Kingdom of Saudi Arabia result from colonization by both the ancestral African and the global domestic forms

    Abstract The Aedes aegypti (Linnaeus, 1762) mosquito is the main vector of dengue, chikungunya and Zika and is well established today all over the world. The species comprises two forms: the ancestral form found throughout Africa and a global domestic form that spread to the rest of the tropics and subtropics. In Saudi Arabia, A. aegypti has been known in the southwest since 1956, and previous genetic studies clustered A. aegypti from Saudi Arabia with the global domestic form. The purpose of this study was to assess the genetic structure of A. aegypti in Saudi Arabia and determine their geographic origin. Genetic data for 17 microsatellites were collected for A. aegypti ranging from the southwestern highlands of Saudi Arabia on the border of Yemen to the north‐west in Madinah region as well as from Thailand and Uganda populations (as representatives of the ancestral African and global domestic forms, respectively). The low but significant level of genetic structuring in Saudi Arabia was consistent with long‐distance dispersal capability possibly through road connectivity and human activities, that is, passive dispersal. There are two main genetic groupings in Saudi Arabia, one of which clusters with the Ugandan population and the other with the Thailand population with many Saudi Arabian individuals having mixed ancestry. The hypothesis of genetic admixture of the ancestral African and global domestic forms in Saudi Arabia was supported by approximate Bayesian computational analyses. The extent of admixture varied across Saudi Arabia. African ancestry was highest in the highland area of the Jazan region followed by the lowland Jazan and Sahil regions. Conversely, the western (Makkah, Jeddah and Madinah) and Najran populations corresponded to the global domesticated form. Given potential differences between the forms in transmission capability, ecology and behaviour, the findings here should be taken into account in vector control efforts in Saudi Arabia
