Dataset of the study "Bridging cultural studies and learning science: An investigation of social media use for Holocaust memory and education in the digital age"
<p>This Zenodo item contains the dataset of the study: Manca, S. (2020). “Bridging cultural studies and learning science: An investigation of social media use for Holocaust memory and education in the digital age".</p> <p>Abstract</p> <p>Along with advances in communication technology that are making new forms of historical memorialization and education available, social media are researched as valuable tools for supporting forms of digital memory and for engaging students and teachers about historical knowledge and moral education. This study aims to map the current state of Holocaust remembrance and Holocaust education and to identify main topics of research in the two areas. It adopts a mixed-method approach that combines qualitative analysis with bibliometric approaches to review publications that use social media for digital memory and history education about the Holocaust. Results based on 28 publications reveal several research topics and that, despite some common theoretical references, the two subfields mostly rely on separate conceptual backgrounds. While Holocaust remembrance is a well-established research field, there are few studies and a lack of theoretical elaboration about social media use for teaching and learning about the Holocaust.</p>
Data from: Petrol exhaust pollution impairs honey bee learning and memory
Volatile organic compounds (VOCs) serve as important infochemicals, mediating several ecological interactions including herbivory and pollination. Atmospheric pollutants including traffic-related air pollution may impair the detection of VOCs used by insects in insect-plant interactions. We investigated the indirect effect of petrol exhaust pollution on olfactory learning and memory (short and long term) in honey bees. Using appetitive olfactory conditioning, we trained bees to learn one of four floral VOC profiles; linalool, dipentene, myrcene and geranium. VOCs were unpolluted or polluted with exhaust collected from a petrol generator. Exhaust emissions included concentrations of CO (246.07 + 17 ppm), NO (20.50 + 6.90 ppb) and NO2 (20.93 + 0.05 ppb) consistent with those typically encountered in urban areas and near roads. Once bees had learnt the training VOC, we tested whether they could recognise that VOC 1 hour, 24 hours and 48 hours post-training. Bees took significantly longer to learn polluted VOCs and forgot them faster than unpolluted ones. We also tested the 'masking' potential of pollution on floral VOCs. Using Gas Chromatography Mass Spectroscopy we noted differences in the chemical profile of polluted versus unpolluted VOCs and tested whether bees could recognise polluted VOCs if trained using unpolluted ones. For several VOCs tested, bees could distinguish between polluted and unpolluted VOCs. Ultimately, our results show that air pollution changes the recognition and retention of floral VOCs by bees which may consequently impact foraging efficiency.
Data from: Tandem-running and scouting behavior are characterized by up-regulation of learning and memory formation genes within the ant brain
Tandem-running is a recruitment behavior in ants that has been described as a form of teaching, where spatial information possessed by a leader is conveyed to following nestmates. Within Temnothorax ants, tandem-running is used within a variety of contexts, from foraging and nest relocation to – in the case of slavemaking species – slave raiding. Here, we elucidate the transcriptomic basis of scouting, tandem-leading, and tandem-following behavior across two species with divergent lifestyles: the slavemaking Temnothorax americanus and its primary, non-parasitic host T. longispinosus. Analysis of gene expression data from brains revealed that only a small number of unique differentially-expressed genes are responsible for scouting and tandem-running. Comparison of orthologous genes between T. americanus and T. longispinosus suggests that tandem-running is characterized by species-specific patterns of gene usage. However, within both species, tandem-leaders showed gene expression patterns median to those of scouts and tandem-followers, which was expected, as leaders can be recruited from either of the other two behavioral states. Most importantly, a number of differentially-expressed behavioral genes were found, with functions relating to learning and memory formation in other social and non-social insects. This includes a number of up-regulated receptor genes such as a glutamate and dopamine receptor, as well as serine/threonine protein phosphatases and kinases. Learning and memory genes were specifically up-regulated within scouts and tandem-followers, not only reinforcing previous behavioral studies into how Temnothorax navigate novel environments and share information, but also providing insight into the molecular underpinnings of teaching and learning within social insects.
Data from: Quantifying the impact of pesticides on learning and memory in bees
1) Most insecticides are insect neurotoxins. Evidence is emerging that sublethal doses of these neurotoxins are affecting learning and memory of both wild and managed bee colonies; exacerbating the negative effects of pesticide exposure and reducing individual foraging efficiency. 2) Variation in methodologies and interpretation of results across studies has precluded the quantitative evaluation of these impacts that is needed to make recommendations for policy change. It is not clear whether robust effects occur under acute exposure regimes (often argued to be more field-realistic than the chronic regimes upon which many studies are based), for field-realistic dosages, and for pesticides other than neonicotinoids. 3) Here we use meta-analysis to examine the impact of pesticides on bee performance in proboscis extension-based learning assays, the paradigm most commonly used to assess learning and memory in bees. We draw together 104 (learning) and 167 (memory) estimated effect sizes across a diverse range of studies. 4) We detected significant negative effects of pesticides on learning and memory (i) at field realistic dosages, (ii) under both chronic and acute application, and (iii) for both neonicotinoid and non-neonicotinoid pesticides groups. 5) We also expose key gaps in the literature that include a critical lack of studies on non-Apis bees, on larval exposure (potentially one of the major exposure routes), and on performance in alternative learning paradigms. 6) Policy implications. Procedures for the registration of new pesticides within EU member states now typically require assessment of risks to pollinators if potential target crops are attractive to bees. However, our results provide robust quantitative evidence for subtle, sublethal effects, the consequences of which are unlikely to be detected within small-scale pre-licensing laboratory or field trials, but can be critical when pesticides are used at a landscape scale. Our findings highlight the need for long-term post-licensing environmental safety monitoring as a requirement within licensing policy for plant protection products.
Data from: Memory for lectures: how lecture format impacts the learning experience
The present study investigated what impact the presentation style of a classroom lecture has on memory, mind wandering, and the subjective factors of interest and motivation. We examined if having a professor lecturing live versus on video alters the learning experience of the students in the classroom. During the lectures, students were asked to report mind wandering and later complete a memory test. The lecture format was manipulated such that all the students received two lectures, one live and one a pre-recorded video. Results indicate that lecture format affected memory performance but not mind wandering, with enhanced memory in the live lectures. Additionally, students reported greater interest and motivation in the live lectures. Given that a single change to the classroom environment, professor presence, impacted memory performance, as well as motivation and interest, the present results have several key implications for technology-based integrations into higher education classrooms.
Maternal sweeteners intake modulates gut microbiota and exacerbates learning and memory processes in adult male offspring
<p>Background: There is increasing evidence that gut microbiota in offspring is derived in part from maternal environment such as diet. Thus, sweeteners intake including caloric or non-caloric, during perinatal period can induce gut dysbiosis and program the offspring to develop cognitive problems later in life.<br> Objective: To determine the effect of maternal high-sweeteners intake during gestation and lactation on gut microbiota shifts in adult male offspring rats and the impact on cognitive dysfunction.</p> <p>Methods: Thirty-four male pups from dams fed standard diet (Control-C, n = 10), high-sucrose diet (HS-C, n = 11), high-honey diet (Ho-C, n = 8) and high-stevia diet (HSt-C, n = 5) were fed standard diet after weaning and body weight and food intake were recorded once a week for 26 weeks. Learning and memory tests were performed at week 23 of life using the Barnes maze. Fecal samples from the breastfeeding and adulthood periods were collected and analyzed by sequencing the 16S rRNA V3-V4 region of gut microbiota.</p> <p>Results: Maternal high-sucrose and stevia diets programmed the male offspring and changes in microbial diversity by Shannon index were observed after weaning (p < 0.01). Furthermore, maternal high-stevia diet programming lasted into adulthood. The increase of Firmicutes abundance and the decrease in phylum Bacteroidetes was significantly in HS-C and HSt-C groups. This led to an increase in the Firmicutes/Bacteroidetes index although only in HS-C group was statistically significant (p < 0.05). Of note, of the downstream gram-negative Bacteroidales and the upregulation of the gram-positive Clostridiales abundance contribute to cognitive dysfunction.</p> <p>Conclusion: These results suggest that dams fed a high-sucrose and stevia diets during gestation and lactation favor a deficient memory performance in adult male offspring rats through shifts gut microbiota diversity and relative abundance at several taxa.</p>
