Women and their Quest for Identity in Arupa Kalita Patangia's Short Stories
Authors: Himabindu S. , Kumar R. Soujanya
Published: January 2023

The stories woven in these tell-tales of women are enveloped with the responsibility of the stories as testimonies of trauma which need attention and focus. The theme of displacement and estrangement are seen in these texts. According to Freud, when one witnesses a truth which is not available to them, the other and the subject are to bear the testimony. This other, subject or the listener become the witness of the trauma. The regular lives of the characters are enveloped with traumatic events. These survivors, the mere witnesses to the brutality cannot explain their experiences in words. They sometimes get into the guilt of forming a false memory due to silence which completely distorted their memory. They reach the saturation point wherein they are unable to explain the situation they are dealing with. Looking at a different perspective, this silence functions a secured wall for them, as they live in this enclosure without any past memories or may be distorted memories of past. Once they step out of this wall, they relive the disaster again in their distorted memories of past.  This paper examines various female characters within their geographical settings, dwelling in the patriarchal society, limited to the horizons set by the dominant males, their thought processes and patterns, aspirations, feelings, beliefs and ultimately their own way of looking at life. My research focuses on few observations of portrayal of women and their subjection in the patriarchal domain in the selected short stories of Arupa Patangia Kalita with a view of exploring the female characters and their responses to their circumstances amidst the conflicting themes of identity.

India, along with the contemporary and colonial history of the postcolonial culture, is seen to offer the study's a rich site that has intertextuality and influence. Furthermore, British imperialism is far more pragmatic as compared to several colonial powers. The motivation is not evangelical but economic. Under the emergence of Orientalism”, India was the first Nation to lay literary impact on the West, such an equation was then reversed during colonial intervention. The changes made by the British in the society of India appeared to be at the top. Where few critics of India are only focused on denouncing and acclaiming the effect of West, Indian writers discriminating response gives complex instances of intertextuality amd influence being reception forms. The literary movement has been shaped by values and essential beliefs of traditional attitude, culture, social life and politics of local people. Authority of British along with the Indian subcontinent ruling power halted for more than two hundred years. Furthermore, it turns simple when you need to have an understanding of the English Literature history being related to the English people life. This attitude across the educational, social, and cultural way of living. The movement of the British colony in the given subcontinent has the testimonial impact of the literature on the people social life style.

According to researchers, Ulaanbaatar, the capital city of Mongolia, is in an active seismic zone, and more active faults around the city have been discovered in the last few decades. This is an alarming news for the city that has been expanding and developing rapidly. Therefore, consideration of the construction of structures that can withstand strong earthquakes has been becoming a complex problem from economic perspective and urban planning. This study aims to develop response spectra for all and any structure constructs in the city. To complete this requirement, we generated maximum response spectra correlating different soil classes, and taking into considering all potential active sources around the city. In this research work, we have proposed various response spectra that are associated with five different soil classes, and these response spectra can be used for the city.
Comprehension of double-center embedded relatives in Italian: a case for hierarchical intervention
Authors: Sala Marco , Bettelli Giulia , Giustolisi Beatrice , Vergallito Alessandra , Romero Lauro Leonor Josefina , Cecchetto Carlo
Published: January 2023

Object relatives are more difficult to process than subject relatives. Several sentence processing models have been proposed to explain this difference. As double-center embedding relatives contain several long-distance dependencies, they are an ideal configuration to compare sentence processing models. The main aim of the present study was to compare the predictions of the featural Relativized Minimality approach with the ones of other relevant sentence processing models.
57 Italian-speaking healthy adults answered comprehension questions concerning the first, second, or third verb to appear in both double-center embedding and control sentences. Results show that questions concerning the matrix verb of double-center embedding structures were significantly easier and were associated with faster response times than questions concerning the embedded verbs. Furthermore, in object double-center embedding relatives the questions concerning the verb of the most embedded clause were easier than the ones concerning the verb of the intermediate embedded clause.
This pattern of results is consistent with featural Relativized Minimality but cannot be fully explained by other sentence processing models.

Pengidentifikasian kinerja yang terdiri atas defleksi, beban saat terjadi kelelehan dan putus serta kekakuan dilakukan menggunakan software Ansys 2020 R2. Variasi jarak lubang balok Kastela ke tumpuan digunakan rasio terhadap tinggi profil setelah dikastela yaitu 0,3H, 0,6H, 0,9H, 1,2H dan 1,5H. Hasil pemodelan menunjukkan bahwa penambahan jarak lubang balok Kastela terhadap tumpuan dapat menignkatkan beban yang menyebabkan leleh pertama, meningkatkan beban yang mengakibatkan putus, menurunkan nilai defleksi dan meningkatkan nilai kekakuan. Untuk penggunaan pada struktur bangunan, diperlukan pertimbangan yang baik karena beban saat leleh balok normal lebih tinggi dari semua variasi jarak lubang ke tumpuan yang dimodelkan
DAYA IKAT NORMA DILUAR PERJANJIAN KE DALAM PERJANJIAN DAN AKIBAT HUKUMNYA
Authors: Januar Inri , Siringoringo Poltak , Saragih Radisman
Published: January 2023

Perjanjian dan Undang-Undang menjadi dasar lahirnya perikatan. Walaupun perjanjian di buat berdasarkan kesepakatan para pihak tidak berarti pihak-pihak dalam perjanjian terhindar dari ketentuan yang berlaku dalam peraturan perundang-undangan. Sifat mengikatnya peraturan perundang-undangan ke dalam suatu perjanjian dengan tegas tertulis dalam Kitab Undang-Undang Hukum Perdata (KUHPerdata). Pemahaman penting setelah itu apakah sesuatu yang secara diam-diam tadi dianggap masuk kedalam perjanjian maka bila tidak dipenuhi akan dikualifikasikan wanprestasi atau tetap sebagai perbuatan melawan hukum (PMH). Dalam pengadilan pemisahan wanprestasi dan PMH sangat tegas dan tidak bisa disatukan berdasarkan yurisprudensi. Pasal 1349 KUHPerdata Jo pasal 1339 KUHPerdata telah menjawab bila kepatutan, kebiasaan dan undang-undang dianggap dimasukkan dalam perjanjian maka itu masuk sebagai perjanjian. Kebebasan berkontrak mempunyai kontribusi penting berkaitan dengan paham individualisme. Dengan tetap memperhatikan kondisi individu yang terikat dengan masyarakat maka hukum bertujuan mencari kepentingan individu yang selaras serasi dan seimbang dengan kepentingan masyarakat. Oleh karenanya bila kepatutan, kebiasaan dan undang-undang yang secara diam-diam masuk dalam perjanjian tidak dilaksanakan maka perbuatannya dikualifikasikan sebagai perbuatan melawan hukum.

Published: January 2023

This work aims to study the management of Lepidoptera defoliators of Quercus spp. using essential oil of Pinus halepensis needles. In this context, laboratory trials of two concentrations (0.1 % and 0.5%) compared with ethanol (negative control) and delthametrin (positive control) were tested by contact action on 3rd, 4th and 5th instars larvae of two outbreak species: the Tortricidae, Tortrix viridana and the Geometridae, Operophtera brumata. Results revealed that P. halepensis essential oil has significant insecticidal potentials on both Lepidoptera species. Essential oil at 0.1 % was three time more efficient on the 3rd instar of T. viridana than on O. brumata. However, mature larvae (4th and 5th instars) took more time to die. The major components of P. halepensis were α-pinene (46.1%) and β-myrcene (9.5%) that may show their insecticidal effectiveness on these pests.

In conclusion, these results are promoting and seems to be of major importance in regulating pests but not outbreaks. Thus, further studies are required to isolate bioactive components and to elucidate the insecticidal mechanisms of P. halepensis.

Authors: Miranbaygi A. , Moghimi M. , Eghbal Ahmadi M. Hosein
Published: January 2023

An artificial neural network (ANN) is one of the computational methods that, through the learning process and using simple processors called neurons, tries to give a mapping between the input variables and the output variables. In this paper, six different recurrent dynamic ANN models are proposed to predict the air pollutant concentrations in city of Tehran, Iran. There is no need to know the details of the governing phenomena to develop the ANN models.The chemical composition as the air pollutants are consisting of NO2, SO2, CO, O3, PM10, and PM2.5. The proposed models are designed with an input layer consisting of meteorological variables and previous sampling times of each output variable. The models have the capability for air pollutant concentration prediction for 24 hours later. The results show that the developed models for NO2, SO2, CO, O3, PM10, and PM2.5 have the values of coefficient of determination (­R2) equal to 0.91, 0.95, 0.94, 0.97, 0.94, and 0.93. Also, the Normalized Root Mean Square Error (NRMSE) is equivalent to 0.0355, 0.2577, 0.047, 0.0397, 0.0270, and 0.0445 for NO2, SO2, CO, O3, PM10, and PM2.5 models, respectively.

The results show that they all models have high accuracy and a low error value. The results may be because the model uses an almost complete set of input variables. Also the model used three sampling times as input variables through a recurrent structure to capture the dynamic behavior. The number of sampling times used as input variables through a recurrent structure that is related to the dynamic conditions of the model.

En la presente investigación se diseñaron hidrogeles a base de redes poliméricas semi-interpenetradas (semi-IPN) de colágeno-poliuretano-pectina, con diferente concentración de pectina (10-40 %m) y se evaluó su efecto en la biocompatibilidad in vitro. La pectina utilizada en este trabajo fue extraída enzimáticamente a partir de cáscaras de naranja. Los parámetros peso equivalente, acidez libre, porcentaje de metoxilo, grado de esterificación y porcentaje de ácido anhídrido galacturónico (AAG) de la pectina fueron determinados de acuerdo con la metodología propuesta por Owens1. Los hidrogeles fueron caracterizados por FTIR y SEM. Además, se evaluó el grado de entrecruzamiento, hinchamiento y módulo de almacenamiento de los hidrogeles. La biocompatibilidad de los hidrogeles se evaluó a través de ensayos de viabilidad celular con monocitos y fibroblastos. Además, se evaluó la actividad hemolítica de los hidrogeles. Altas concentraciones de pectina disminuyen la capacidad de hinchamiento significativamente, y promueven una ligera mejora de la reticulación y un incremento significativo del módulo de almacenamiento de la matriz semi-IPN. La caracterización por FTIR y SEM confirmó la formación de redes semi-interpenetradas de colágeno-poliuretano-pectina. Los hidrogeles formulados no poseen carácter citotóxico. El porcentaje de viabilidad de fibroblastos alcanzó el 75% mientras que la viabilidad de monocitos alcanzó el 105% hasta por 48 h de incubación. Las formulaciones que contienen 10 y 20 %m de pectina mostraron mejor biocompatibilidad in vitro, ya que la presencia de altas regiones granulares semi-interpenetradas en la matriz colágeno-poliuretano muestran impactar en el metabolismo celular.
Human Development and Macroeconomic Shocks in Nigeria: An Empirical Investigation

Published: January 2023

This paper explores how human development responds to selected macroeconomic shocks in Nigeria. The study employed the Sen’s capabilities approach as the analytical approach and posited that the level of education, health status, quality of investment, technology, and government fiscal and monetary policies are plausible determinants of human development. We used the Structural Vector Autoregression (SVAR) to estimate the responses of such selected shocks, which are inflation, interest rate, government capital expenditure, exchange rate, current account balance, and savings shocks. The Forecast Error Variance Decomposition (FEVD) and the Impulse Response (IR) showed that a fiscal policy shock is the major factor influencing human development outcomes. This finding underscored the important role government plays in enhancing the well-being of its citizens. Fiscal policy tools (such as investment in education, health, housing, and infrastructure) are essential for human development. In particular, the human development outcome is found to respond positively to shocks from real interest rates, which are felt significantly in the short run. We concluded that human development is negatively affected by a sudden decline in the federal government’s capital budget expenditure.

Many archeological sites that exist today are associated with catastrophic events in the past. Some archeological remains were found buried in volcanic ash materials, flood deposits, and even it related to tsunami that was happened in the past. For example, a paleotsunami research that was conducted in the western coast of Aceh has identified that one of the paleotsunami occurance which happened in 15th century might have responsible for the cultural hiatus in the northern of Sumatra during that century. It was hypothesized that the 15th century’s tsunami destroyed the pre-15th century civilizations and cultures. Unfortunately, the study of disaster geoarcheology especially in Indonesia is not a popular research topic, the connection between the archeological remains with the occurrence of disaster is still not properly discovered. Through the geoarcheological studies, not only the community response to the disaster can be identified but also the recurrence interval of the disaster can be predicted. For example, in Simeuleu, Aceh, the local wisdom of smong, a tradition that still exists today, has been proven to save many lives from tsunamis. In this paper, examples of geoarcheological studies will be discussed. Our understanding of the history of the archeological sites and their connection with the disaster is an important aspect and this information must be applied for the disaster mitigation and expected to be able to support achieving the goal of sustainable development.

The tombs of the kings in the eastern part of Kalimantan are spread over six districts in three provinces. The figures buried were the king, son of the king, queen, prime minister and other members of the royal family. This study aims to determine the letters and language used to write inscriptions on these tombs. The data collection method used is an exploratory survey, documented using photographs, drawings and maps or plans. The results showed that most of the graves were inscribed, some using Arabic letters, some using Bugis letters and some using Latin letters. The languages ​​spoken include Arabic, Malay, and Bugis. These inscriptions can be categorized as calligraphy using media of wood, stone and metal. Regarding the use of these languages, it can be concluded that there is a connection with various things, including the people who inhabit the area, the blend of local culture with foreign culture, and the contents of the inscriptions. The use of the Malay language shows that the language is used widely in various regions of the archipelago, the use of the Bugis language is related to the existence of the Bugis people who inhabit the area, while the Arabic language is used to display monotheistic sentences, verses of the Koran and the title of the Prophet Muhammad.

Several cities in Indonesia that was built and developed during the colonial era can be categorized as planned cities and grew due to industrial and mining activities. Manggar is a city that grew due to tin mining activities on the east of Belitung Island. This paper will examine the cityscape of Manggar which developed from a simple settlement into a complex settlement. In addition, this paper will also discuss ethnic segregation in Manggar which is one of the characteristics of the city that grew in the colonial era. The source of the data in this article is the result of archaeological research conducted by the Archaeological Center of South Sumatra in 2021. This research compared archaeological data with historical data together with old maps. The results of the analysis showed that Manggar had four phases of development between the early nineteenth and twentieth centuries. In addition, there is also a clear pattern of separation between settlement of one ethnicity with the other ethnicities scattered in Manggar City. The separation of these settlements was a manifestation of the policy of the Dutch East Indies Government issued in 1854 regarding the stratification of social classes based on ethnic groups.

The China Town in the past was one of the important trading ports in the archipelago, this is proven by the abundance of findings from archaeological excavations at the site. The decline of China Town as a trading city is recorded in people's memories in the form of speech stories. The story that is quite well known and developed in the community that makes China Town abandoned by its inhabitants is due to the attack of kepah (a type of sea shell) that comes from the sea. As a result, people flocked to leave the city. This story continues to this day. This paper aims to explain scientifically the speech stories that developed in the community associated with data from archaeological research that has been carried out at the site. From the results of excavations carried out, it is found that in various locations, kitchen waste is almost always found in the form of concentrations of shells. This results in environmental damage in the form of river silting, and the closure of the soil surface due to shell waste. These two things make China Town uncomfortable to live in and then abandoned.
