Memes of Care: Good Morning Images and Digital Care among Older People in Taiwan

Every morning, images carrying greetings and pictures of girls, cute animals, or beautiful flowers are circulated among Taiwanese older people on the messaging app LINE. These “good morning images” (GM images) are building a new social network for seniors, and its ritual of exchange has produced a digital subculture. In this article, I will be considering these images as “memes of care.” While memes for younger people are usually humorous and meant to raise a laugh, for older people, GM images are about care and connection. However, care is never innocent and not always desirable, and GM images have joined a sharing culture within LINE that precipitates the spread of unverified, authorless rumors. By examining the “care-ful” feelings, doings, and obligations of GM images, I show how older people actively participate in the practice of digital care so as to open up to “as well as possible” reconfigurations engaged with troubled presents—that is, the pandemic and social isolation on the one hand, and the proliferation of false and misleading information on the other.

INTELLIGENT ACQUISITION METHOD OF HERBACEOUS FLOWERS IMAGE BASED ON THEME CRAWLER, DEEP LEARNING AND GAME THEORY

In order to obtain a large amount of training data in a short time, flower classification is carried out through image processing and deep learning algorithms based on game theory and optimization. The Python web crawler technology is used to write the image and short video crawler programs based on the Chinese name of herbal flowers, and the target detection model is used to screen the flower image on the basis of the static frame of the segmented video, so as to improve the speed and accuracy of image acquisition. The result show that the use of theme crawler technology can obtain the image of herbaceous flowers effectively; target detection can greatly improve the image utilization, the number of samples can be increased by 3~10 times, and the average error detection rate is only 3.62%; the GAN (GenerativeAdversarial Network) is a deep learning model based on game theory. GAN model can generate realistic flower pictures, which provides a new research idea to solve the problem of lack of agriculture data set at present, and shows the feasibility of intelligent data collection method for herbaceous flowers.

The effects of daily step goals of 10,000, 12,500, and 15,000 steps per day on neural activity to food cues: A 24‐week dose‐response randomized trial

IntroductionThe purpose of this study was to examine the effect of different levels of sustained physical activity on neural reflections of attention allocated toward food cues in first year college women.MethodsSeventy‐nine first‐year college women (18.6 ± 0.5 years) were recruited to participate in the study. Women were randomly assigned to a daily step goal of 10,000, 12,500, or 15,000 for 24 weeks. Once during weeks 16–24, participants were shown pictures of plated meals or flowers with the neural response measured using the P300 and late positive potential (LPP) components of the scalp‐recorded event‐related potential. Diet was assessed using the automated 24‐h recall.ResultsBoth the P300 and LPP amplitudes were significantly more positive to food versus flower pictures (ps < .001). There was no interaction between step group and picture condition for the P300 and LPP. However, the 12,500‐step group showed a significantly elevated LPP amplitude in comparison to the other groups for both food and flowers (F(2,74) = 8.84; p < .001). The effect size for the combined results (food and flowers) was 0.56 between 10,000 and 12,500‐step groups, and 0.75 between the 12,500‐ and 15,000‐step groups. In addition, the 12,500 group reduced caloric consumption over the course of the intervention (t(1,74) = 3.35, p = .001, dz = 0.59).ConclusionHabitual physical activity of 10,000, 12,500, or 15,000 steps per day does not preferentially alter neural reflections toward food cues compared to flowers. There may be a nonlinear response to pleasant visual cues, with 12,500 steps per day eliciting higher LPPs than either 10,000 or 15,000.

Naïve and Experienced Honeybee Foragers Learn Normally Configured Flowers More Easily Than Non-configured or Highly Contrasted Flowers

Angiosperms have evolved to attract and/or deter specific pollinators. Flowers provide signals and cues such as scent, colour, size, pattern, and shape, which allow certain pollinators to more easily find and visit the same type of flower. Over evolutionary time, bees and angiosperms have co-evolved resulting in flowers being more attractive to bee vision and preferences, and allowing bees to recognise specific flower traits to make decisions on where to forage. Here we tested whether bees are instinctively tuned to process flower shape by training both flower-experienced and flower-naïve honeybee foragers to discriminate between pictures of two different flower species when images were either normally configured flowers or flowers which were scrambled in terms of spatial configuration. We also tested whether increasing picture contrast, to make flower features more salient, would improve or impair performance. We used four flower conditions: (i) normally configured greyscale flower pictures, (ii) scrambled flower configurations, (iii) high contrast normally configured flowers, and (iv) asymmetrically scrambled flowers. While all flower pictures contained very similar spatial information, both experienced and naïve bees were better able to learn to discriminate between normally configured flowers than between any of the modified versions. Our results suggest that a specialisation in flower recognition in bees is due to a combination of hard-wired neural circuitry and experience-dependent factors.

AN OTSU image segmentation based on fruitfly optimization algorithm

Despite its simplicity and high accuracy, the real-time efficiency of OTSU segmentation is not high. In order to promote the real-timeliness of image segmentation, this paper introduces the fruitfly optimization algorithm (FOA) to OTSU segmentation, creating an FOA-OTSU segmentation algorithm. In the proposed algorithm, the optimal threshold for segmentation is searched for by the FOA. The classic Lena picture, Flower picture and Cameraman picture were used for simulation experiment, and the results were evaluated by signal-to-noise ratio (SNR) and peak signal-to-noise ratio (PSNR). The results show that the segmentation time is reduced by about 50.0% on the premise of the PSNR and SNR evaluation criteria and the segmentation effect basically unchanged. The simulations indicate that our method converges faster and consumes fewer time than traditional OTSU algorithm, without sacrificing the segmentation accuracy. The research provides a desirable tool with high real-time performance of rapid image segmentation.

Analisis Makna Kata Hana dan Bunga Sebagai Polisemi (Kajian Linguistik Kognitif)

Cognitive linguistics views that the meaning of a word, especially in polysemi, doesnot just appear, but there is something that motivates and lies behind it. To describethe relationship between meanings in polysemy can be done through language style.Categorization and comparing activities can occur in the form of metaphorical, metonymy,and synchronic forms. The word 'flower' in Indonesian with ana hana ’in Japanese hasalmost the same meaning and function. This study aims to determine the meaning of theword flower and hana seen from the perspective of cognitive linguistics. This study usesa qualitative descriptive method by taking data from various sources. The results of thisstudy are 1) in general the meaning of the word "flower" is something beautiful, calmingthe heart, pleasing to the eye, pleasant to hear, fragrant smell; 2) in general the meaningof the word "hana" is a beautiful woman; Wreaths; flower picture card game; colorful,striking, brilliant, beautiful.Keywords: cognitive linguistics, polisemi, hana, bunga

No Evidence for the Watching-Eyes Effect on Human Impulsivity.

People often become more altruistic when they think or feel that someone is watching them. Known as the “watching-eyes effect,” this is argued to be caused by the motivation to gain and maintain a positive social reputation as an altruistic individual (the “reputation seeking” mechanism). However, an alternative mechanism underlying the watching-eyes effect could be that people suppress their impulsive tendency to pursue benefit rather than increase their altruism, and this may lead to apparent increases in altruistic tendencies. This “suppressing impulsivity” mechanism is considered intrapersonal rather than socially mediated which is associated with “reputation seeking.” We examined whether the suppressing impulsivity mechanism would be associated with the watching-eyes effect by measuring participants’ impulsivity in the presence of watching-eyes stimuli. In a controlled experiment, we presented life-size pictures of human faces with a direct gaze on a monitor in front of participants taking part in a time-discounting task. Two types of faces, “in-group” (faces of participants’ classmates) and “out-group” (unfamiliar faces) were presented to examine the effect of social attribution. We used a flower picture as a control stimulus. In the time-discounting task, participants chose one of two options: a small amount of money that they could get immediately or a larger amount of money that they could get after a given time interval. The results showed no significant difference in participants’ time-discount rate regardless of the types of stimuli presented during the time-discount task. A post-task questionnaire confirmed that the participants were aware of the presented stimuli and revealed that they paid more attention to the in-group stimuli than to the out-group and flower stimuli, though this difference in attentive states had no effect on their impulsivity during the task. These results suggest that suppressing impulsivity is not a plausible mechanism for the watching-eyes effect. The null effect for the difference between the in-group and out-group stimuli also supports this conclusion. Thus, it is plausible that the watching-eyes effect is caused by the human tendency to boost social reputation and can be mediated by the social relationship with others.

Aplikasi Berbasis Web Untuk Pendeteksian Jenis Bunga Menggunakan Algoritma K-NN

Flowers are part of plants that have a variety of types and forms. Because of the many varieties of flowers it is sometimes difficult to know the name of a flower that we know. It takes a data that can provide clear information about the name of the interest to be searched for the name of the interest. So needed an application that can provide information from the name of flowers through the detection of interest from a flower picture. Flower type detection can be done by knowing countour and color of flowers and using K-NN method for the classification of types of flowers. So in this study made a web-based application for the detection of interest types because later can help the detection of types of flowers quickly and easily online. This application will provide information related to the interest in the search related to the name of the interest. From the results of research conducted to identify the classification of 74.89%.

Reduction of implicit cognitive bias with cathodal tDCS to the left prefrontal cortex.

Implicit associations can interfere with cognitive operations and behavioral decisions without direct intention. Enhancement of neural activity with anodal transcranial direct current stimulation (tDCS) was proposed to reduce implicit associations by means of improved cognitive control. However, a targeted reduction of distractive implicit associations by inhibitory cathodal tDCS, recently shown in spatial-numerical associations, provides an interesting alternative approach to support goal-directed behavior with transcranial brain stimulation. To test this rationale with a sham-controlled cross-over design, a standardized Implicit Association Test (IAT) was performed by 24 healthy participants parallel to 1 mA cathodal or sham tDCS to the left prefrontal cortex. In this double-classification task, insect versus flower pictures and negative versus positive words are mapped together onto two shared response keys with crossed response assignments in separate blocks. Responses were faster when insect + negative and flower + positive stimuli required the same answer (IAT effect). Most critically, the IAT effect was reduced during cathodal tDCS as compared to sham stimulation. Thus, results are consistent with the proposed stimulation rationale, with previous observations, and complementary to previous studies using different tDCS configurations.

Itsy Bitsy Spider…: Infants React with Increased Arousal to Spiders and Snakes.

Attention biases have been reported for ancestral threats like spiders and snakes in infants, children, and adults. However, it is currently unclear whether these stimuli induce increased physiological arousal in infants. Here, 6-month-old infants were presented with pictures of spiders and flowers (Study 1, within-subjects), or snakes and fish (Study 1, within-subjects; Study 2, between-subjects). Infants’ pupillary responses linked to activation of the noradrenergic system were measured. Infants reacted with increased pupillary dilation indicating arousal to spiders and snakes compared with flowers and fish. Results support the notion of an evolved preparedness for developing fear of these ancestral threats.

Automatic recognition of flower species in the natural environment

In this study, we propose a method for the recognition and retrieval of a flower species in the natural environment based on a multi-layer technique, and we also suggest novel applications. First, the study suggests how to capture a flower object that is blooming in the natural environment, as well as the corresponding background. Secondly, an experimental analysis is conducted for the purpose of improving the optimal method of feature extraction for color, texture, and shape. Thirdly, the study developed a flower-image automatic-recognition technology that can be utilized in a mobile environment. We performed experiments on 29,463 images of 300 species of blooming flowers that were collected in South Korea between 2011 and 2014. We found image recognition to be 91.26% for the 1st-ranking recognition of the flower image and 97.40% for the 6th-ranking recognition. These results show that the color–texture–shape features of the flower pictures are the most effective; furthermore, the effectiveness and validity of this suggested method for demonstration services are verified in this paper.

积极情绪背景对词语记忆的影响

本研究采用学习－测验范式，以大学生为被试，通过两个实验考察了不同趋近强度的积极情绪背景材料对词语记忆的影响。研究表明，当使用情绪图片作为学习词语时的背景材料时，高趋近积极情绪背景(美食图片背景)可能比低趋近积极情绪背景(鲜花图片背景)更不利于学习者的编码加工，从而影响其再认表现。当使用真正的鲜花或食物作为学习和记忆测试过程中的背景材料时，低趋近的鲜花背景更可能干扰被试的再认反应。 Selecting undergraduates as participants, the present study examined the effects of low versus high approach-motivated positive affect on memory of words by employing the study-test para-digm. The results showed that, when emotional pictures were as context during learning, high approach-motivated positive affect pictures (delicious food pictures) were more likely to interfere with the encoding process of words and thus impaired recognition performance as compared to low approach-motivated positive affect pictures (flower pictures); when real flowers or delicious foods were as context during learning and test, low approach-motivated flower background was more likely to interfere with participants’ recognition as compared to high approach-motivated food background and neutral background.

Disparity in neural and subjective responses to food images in women with obesity and normal-weight women.

Self-reports tend to differ from objective measurements of food intake, particularly in adults with obesity; however, no studies have examined how neural responses to food (an objective measure) and subjective ratings of food differ by BMI status. This study tested normal-weight women (NWW) and women with obesity (OBW) for group differences in neural indices of attention towards food pictures, subjective ratings of these pictures, and the disparity between objective and subjective measurements. Twenty-two NWW (21.8 ± 1.7 kg/m2 ) and 22 OBW (37.0 ± 5.7 kg/m2 ) viewed food and flower pictures while late positive potential amplitude, an event-related potential, was recorded. Participants rated pictures for arousal and valence. Late positive potential amplitude was larger toward food than flower pictures. OBW self-reported flower pictures as more pleasant than food; NWW showed no difference for pleasantness. There were no significant main effects or interactions for arousal. Standardized scores showed that only on subjective, but not objective, measures did OBW compared with NWW disproportionately indicate food pictures as less pleasant than flowers. Compared with NWW, OBW showed larger discrepancies between neural and subjective reports of attention towards food. Inaccurate self-reports of attention towards food may reduce the efficiency of health interventions.

Japanese monkeys (Macaca fuscata) quickly detect snakes but not spiders: Evolutionary origins of fear-relevant animals.

Humans quickly detect the presence of evolutionary threats through visual perception. Many theorists have considered humans to be predisposed to respond to both snakes and spiders as evolutionarily fear-relevant stimuli. Evidence supports that human adults, children, and snake-naive monkeys all detect pictures of snakes among pictures of flowers more quickly than vice versa, but recent neurophysiological and behavioral studies suggest that spiders may, in fact, be processed similarly to nonthreat animals. The evidence of quick detection and rapid fear learning by primates is limited to snakes, and no such evidence exists for spiders, suggesting qualitative differences between fear of snakes and fear of spiders. Here, we show that snake-naive Japanese monkeys detect a single snake picture among 8 nonthreat animal pictures (koala) more quickly than vice versa; however, no such difference in detection was observed between spiders and pleasant animals. These robust differences between snakes and spiders are the most convincing evidence that the primate visual system is predisposed to pay attention to snakes but not spiders. These findings suggest that attentional bias toward snakes has an evolutionary basis but that bias toward spiders is more due to top-down, conceptually driven effects of emotion on attention capture.

Rapid Categorization of Snakes in the Infant’s Occipital Cortex: Evidence from Fast Periodic Visual Stimulation

Rapid Categorization of Snakes in the Infant’s Occipital Cortex: Evidence from Fast Periodic Visual Stimulation

Predicting Subjective Affective Salience from Cortical Responses to Invisible Object Stimuli.

The affective value of a stimulus substantially influences its potency to gain access to awareness. Here, we sought to elucidate the neural mechanisms underlying such affective salience in a combined behavioral and fMRI experiment. Healthy individuals with varying degrees of spider phobia were presented with pictures of spiders and flowers suppressed from view by continuous flash suppression. Applying multivoxel pattern analysis, we found that the average time that spider stimuli took relative to flowers to gain access to awareness in each participant could be decoded from fMRI signals evoked by suppressed spider versus flower stimuli in occipitotemporal and orbitofrontal cortex. Our results indicate neural signals during unconscious processing of complex visual information in orbitofrontal and ventral visual areas predict access to awareness of this information, suggesting a crucial role for these higher-level cortical regions in mediating affective salience.

Mobile‐based flower species recognition in the natural environment

A system design and new method for recognising a flower's species in a natural environment are proposed. An experimental analysis is conducted to improve the optimal method of feature extraction that is developed for the colour, texture and shape. These results showed that the colour (HS, CbCrCg and RGB), texture (grey level co-occurrence matrix) and shape (zero crossing rate) features for pictures of flowers were the most effective. The study develops flower image recognition technology that can be utilised in a mobile environment.

You See What you Fear: Spiders Gain Preferential Access to Conscious Perception in Spider-Phobic Patients

In phobic individuals, behavioral responses to phobia-related cues are facilitated and brain responses are augmented. It has rarely been investigated whether this preferential processing is accompanied by an altered conscious perception of phobia-related cues. We used binocular rivalry to investigate conscious perception of phobia-related cues in phobic individuals. 21 spider-phobic patients and 20 non-anxious control participants viewed pictures of spiders or flowers, each paired with a neutral pattern under conditions of binocular rivalry. Spider-phobic patients more often reported that they saw spider pictures as the first percept, and the total duration of seeing spider percepts was significantly longer in patients than in non-anxious participants. A second experiment was conducted to rule out that these differences were caused by different response criteria. Results support the validity of self-report in Experiment 1. In sum, predominance of phobia-related cues in binocular rivalry provides evidence that phobia-related cues gain preferential access to visual awareness in phobic individuals.
