Can a brief exposure to nature at the end of a workday enhance sustained attention and long-term memory? Student advisors viewed a video of either a natural environment or a busy city street after work. Then they performed a tone-detection task that was intended to mimic a key feature of their job (being on the telephone). After the nature video, systolic blood pressure increased and response latencies remained stable across time. After the city video, systolic blood pressure remained unchanged from baseline, whereas response latencies increased over time. Self-reports of arousal and emotional state did not differ significantly between videos, whereas memory of the experimental setting was better after viewing the nature video. In sum, a brief contact with nature at the end of a workday may give an individual vigor to complete additional tasks but not improve his or her affect.

Abstract
This study focuses on a discourse practice that metaphorically associates ISIS with an early Islamic sect known as the Kharijites. This practice constructs a discourse that calls back the background knowledge and memory of historical narratives and experiences that create conceptual frames that communicate meanings of war and atrocities. These meanings were used by King Abdullah II of Jordan to justify Jordan's military participation against ISIS (circa 2014–2018). On the basis of the "blending theory" of conceptual metaphor, this study shows how the discourse practice of depicting ISIS as the Kharijites has undergone selective associations with the ideological aim of constructing persuasive and coercive discourses to justify military intervention against ISIS, primarily by foregrounding scripts of threat and victimization. That, in turn, leads to the instigation of illusive and incomplete associations.

AbstractWe explored the causal role of individual and age‐related differences in working memory (WM) capacity in long‐term memory (LTM) retrieval. Our sample of 160 participants included 120 children (6–13‐years old) and 40 young adults (18–24 years). Participants performed a WM task with images of unique everyday items, presented at varying set sizes. Subsequently, we tested participants' LTM for items from the WM task. Using these measures, we estimated the ratio at which items successfully held in WM were recognized in LTM. While WM and LTM generally improved with age, the ability to transfer information from WM to LTM appeared consistent between age groups. Moreover, individual differences in WM capacity appeared to predict LTM encoding. Overall, these results suggested that LTM performance was constrained by experimental, individual, and age‐related WM limitations. We discuss the theoretical and practical implications of this WM‐to‐LTM bottleneck.

Air temperature is one of the main factors for describing the weather behaviour in the earth. Since Indonesia is located on and near equator, then monitoring the air temperature is needed to determine either global climate change occurs or not. Climate change can have an impact on biological growth in various fields. For instance, climate change can affect the quality of production and growth of animal and plants. Therefore, air temperature prediction is important to meteorologists and Indonesian government to provide information in many sectors. Various prediction algorithms have been used to predict temperature and produce different accuracy. In this study, the deep learning method with Long Short-Term Memory (LSTM) model is used to predict air temperature. Here, the results show that LSTM model with one layer and Adaptive Moment Estimation (ADAM) optimizer produce accuracy which is 32% of , 0.068 of MAE and 0.99 of RMSE. Moreover, here, ADAM optimizer is found better than Stochastic Gradient Descent (SGD) optimizer.

Abstract Estimates of government expenditure for the next period are very important in the government, for instance for the Ministry of Finance of the Republic of Indonesia, because this can be taken into consideration in making policies regarding how much money the government should bear and whether there is sufficient availability of funds to finance it. As is the case in the health, education and social fields, modeling technology in machine learning is expected to be applied in the financial sector in government, namely in making modeling for spending predictions. In this study, it is proposed the application of Long Short-Term Memory (LSTM) Model for expenditure predictions. Experiments show that LSTM model using three hidden layers and the appropriate hyperparameters can produce Mean Square Error (MSE) performance of 0.2325, Root Mean Square Error (RMSE) of 0.4820, Mean Average Error (MAE) of 0.3292 and Mean Everage Presentage Error (MAPE) of 0.4214. This is better than conventional modeling using the Auto Regressive Integrated Moving Average (ARIMA) as a comparison model. ; Perkiraan pengeluaran belanja pemerintah untuk periode kedepan merupakan hal yang sangat penting di pemerintah dalam hal ini pada Kementerian Keuangan Republik Indonesia, karena hal ini dapat dijadikan bahan pertimbangan dalam mengambil kebijakan terkait berapa nilai uang yang harus ditanggung pemerintah serta apakah ada ketersediaan dana yang cukup dalam membiayai belanja tersebut untuk periode yang akan datang. Seperti halnya pada bidang kesehatan, pendidikan dan sosial, teknologi pemodelan pada Machine Learning diharapkan dapat diterapkan di bidang keuangan pada pemerintahan, yaitu dalam membuat pemodelan untuk prediksi belanja. Pada penelitian ini, diusulkan penerapan model Long Short-Term Memory (LSTM) untuk prediksi belanja. Eksperimen menunjukkan model LSTM dengan menggunakan tiga hidden layers dan hyperparameter yang tepat dapat menghasilkan performa Mean Square Error (MSE) sebesar 0.2325, Root Mean Square Error (RMSE) sebesar 0.4820, Mean Average Error (MAE) sebesar 0.3292 dan Mean Everage Presentage Error (MAPE) sebesar 0.4214. Ini lebih baik dibandingkan pemodelan konvensional menggunakan Auto Regressive Integrated Moving Average (ARIMA) sebagai model pembanding.

Daniel Pauly's concept of the shifting baseline syndrome (SBS) focuses on problems of scientists' long-term change perception and in particular on the forgetting of reference points established by preceding generations. Once introduced in the context of fisheries science, the concept is currently widely applied in neighbouring disciplines, but has only begun to enter the field of social and cultural science.
This article considers the shifting baseline syndrome in an interdisciplinary context and describes suggestions emerging that way: With regard to the concept's context of origin, it shows that approaches from social and cultural science such as the sociology of knowledge and memory studies allow a more detailed and comprehensive understanding of questions addressed by the concept. Conversely, with regard to social and cultural science, this concept originating from natural science suggests the relevance of autobiographical, communicative, cultural and future memory for studying problems and potentials of sustainability and long-term change perception in general.

The text classification process has been well studied, but there are still many improvements in the classification and feature preparation, which can optimize the performance of classification for specific applications. In the paper we implemented dictionary based approach and long-short term memory approach. In the first approach, dictionaries will be padded based on field's specific input and use automation technology to expand. The second approach, long short term memory used word2vec technique. This will help us in getting a comprehensive pipeline of end-to-end implementations. This is useful for many applications, such as sorting emails which are spam or ham, classifying news as political or sports-related news, etc

This research examined the role of working memory (WM) capacity and long-term working memory (LT-WM) in flight situation awareness (SA). We developed spatial and verbal measures of WM capacity and LT-WM skill and then determined the ability of these measures to predict pilot performance on SA tasks. Although both spatial measures of WM capacity and LT-WM skills were important predictors of SA performance, their importance varied as a function of pilot expertise. Spatial WM capacity was most predictive of SA performance for novices, whereas spatial LTWM skill based on configurations of control flight elements (attitude and power) was most predictive for experts. Furthermore, evidence for an interactive role of WM and LT-WM mechanisms was indicated. Actual or potential applications of this research include cognitive analysis of pilot expertise and aviation training.

In the marine environment, shore-based radars play an important role in military surveillance and sensing. Sea clutter is one of the main factors affecting the performance of shore-based radar. Affected by marine environmental factors and radar parameters, the fluctuation law of sea clutter amplitude is very complicated. In the process of training a sea clutter amplitude prediction model, the traditional method updates the model parameters according to the current input data and the parameters in the current model, and cannot utilize the historical information of sea clutter amplitude. It is only possible to learn the short-term variation characteristics of the sea clutter. In order to learn the long-term variation law of sea clutter, a sea clutter prediction system based on the long short-term memory neural network is proposed. Based on sea clutter data collected by IPIX radar, UHF-band radar and S-band radar, the experimental results show that the mean square error of this prediction system is smaller than the traditional prediction methods. The sea clutter suppression signal is extracted by comparing the predicted sea clutter data with the original sea clutter data. The results show that the proposed sea clutter prediction system has a good effect on sea clutter suppression.
