The positive effect of music on source memory

2015

Several studies have investigated how to improve episodic memory performance by manipulating the factors that are crucial for successful encoding. There is an ongoing debate about whether a complex stimulus such as music can improve memory, and in particular memory for words, rather than interfere with correct encoding of information. Therefore, the present study aims to investigate whether verbal episodic memory can be improved by background context of instrumental music. Twenty young adults were asked to memorize different lists of words presented against a background of music, environmental sounds or silence. Their episodic memory performance was then tested in terms of item and source …

Suicide and Ambient Temperature: A Multi-Country Multi-City Study

2019

Background: Previous literature suggests that higher ambient temperature may play a role in increasing the risk of suicide. However, no multi-country study has explored the shape of the association and the role of moderate and extreme heat across different locations. Objectives: We examined the short-term temperature–suicide relationship using daily time-series data collected for 341 locations in 12 countries for periods ranging from 4 to 40 y. Methods: We conducted a two-stage meta-analysis. First, we performed location-specific time-stratified case-crossover analyses to examine the temperature–suicide association for each location. Then, we used a multivariate meta-regression to combine t…

A new method for forecasting energy output of a large-scale solar power plant based on long short-term memory networks a case study in Vietnam

2021

Abstract This paper proposes a new model for short-term forecasting power generation capacity of large-scale solar power plant (SPP) in Vietnam considering the fluctuations of weather factors when applying the Long Short-Term Memory networks (LSTM) algorithm. At first, a configuration of the model based on the LSTM algorithm is selected in accordance with the weather and operating conditions of SPP in Vietnam. Not only different structures of LSTM model but also other conventional forecasting methods for time series data are compared in terms of error accuracy of forecast on test data set to evaluate the effectiveness and select the most suitable LSTM configuration. The most suitable config…

Serum Response Factor-Mediated Gene Regulation in a Drosophila Visual Working Memory

2013

Summary Background Navigation through the environment requires a working memory for the chosen target and path integration facilitating an approach when the target becomes temporarily hidden. We have previously shown that this visual orientation memory resides in the ellipsoid body, which is part of the central complex in the Drosophila brain. Former analysis of  foraging and ignorant mutants have revealed that a hierarchical PKG and RSKII kinase signaling cascade in a subset of the ellipsoid-body ring neurons is required for this type of working memory in flies. Results Here we show that mutants in the ellipsoid body open  ( ebo ) gene, which encodes the actin-binding protein Exportin 6, e…

Forecasting energy output of a solar power plant in curtailment condition based on LSTM using P/GHI coefficient and validation in training process, a…

2022

This study presents how to improve the short-term forecast of photovoltaic plant's output power by applying the Long Short-Term Memory, LSTM, neural networks for industrial-scale solar power plants in Vietnam under possible curtailment operation. Since the actual output power does not correspond to the available power, new techniques (Global Horizontal Irradiance - GHI interval division, P/GHI factor addition (P - Power)) have been designed and applied for processing errors and missing data. The prediction model (LSTM network, structure of hidden layers, number of nodes) has been developed by the authors in a previous work. In this new version of the model, the training technique is improve…

Long-termism e short-termism nella ricerca di strategie di sostenibilità

2021

The focus of legislators, authorities and academics on the temporal dimension of sus-tainable actions has led to the progressive re-emerge of the contrast between long-termism and short-termism, that is frequent indeed in corporate law. The orientation to long-term decisions and attempts to stem the short-term ones have been a main point of recent legislative measures on this topic. This paper aims to critically re-evaluate the above contrast, highlighting some of the most relevant areas that most need regulatory interventions and suggesting abandon-ing the frequent short-term disfavor.

Aging and prospective memory: the role of working memory and monitoring processes

2008

Background and aims: Remembering to execute an earlier planned action is essential in everyday life, and is a prerequisite for independent living in old age. The purpose of the present study was to determine the influence of age in performing a prospective memory (PM) task and to analyze the differential contribution of working memory and attentional monitoring demands. Methods: In Experiment 1, a group of young and two groups of old adults were assigned to one of two low-demanding conditions: a picture-naming task (only-Naming) and a picture-naming plus a PM task (Naming+PM). In Experiment 2, a group of young and two groups of old adults performed one of two high-demanding conditions, in w…

Naming speed and Effortful and Automatic Inhibition in Children with Arithmetic Learning Disabilities

2009

Abstract We report a two-year longitudinal study aimed at investigating the rate of access to numerical and non-numerical information in long-term memory and the functioning of automatic and effortful cognitive inhibition processes in children with arithmetical learning disabilities (ALDs). Twelve children with ALDs, of age 9.3 years, and twelve gender–age-matched controls were involved in the study. Rate of access was measured through digit- and letter-naming tasks, automatic cognitive inhibition was measured using a negative priming paradigm, and effortful cognitive inhibition was measured rating intrusion errors in a working memory task. Children with ALDs suffered from a deficit in the …

The Effects of Short-Term Personal Goals on Subjective Well-Being

2015

Several studies demonstrated that subjective well-being is associated with goal value and perceived progress but their validity is affected by methodological biases. Moreover, a few have analysed the influence of short-term goals. We aimed to analyse how the levels of and changes in short-term goals progress and value influence subsequent levels of and changes in subjective well-being. This study adopted a three-wave longitudinal design with one-month intervals. Four hundred nine participants (186 males; age 19–71) reported their subjective well-being and their two most important goals and rated each over time in terms of value and progress. A latent difference score model revealed that lev…
