Towards Robust River Plastic Detection: Combining Lab and Field-based Hyperspectral Imagery
Authors: Tasseron Paolo , Schreyers Louise , Peller Joseph , Biermann Lauren , van Emmerik Tim
Published: June 2022

Plastic pollution in aquatic ecosystems has increased dramatically in the last five decades, with strong impacts on human and aquatic life. Recent studies endorse the need for innovative approaches to monitor the presence, abundance, and types of plastic in these ecosystems. One approach gaining rapid traction is the use of multi- and hyperspectral cameras. However, most experiments using this approach were in controlled environments, making findings challenging to apply in natural environments. We present a method linking lab- and field-based identification of macroplastics using hyperspectral data (1150-1675 nm). Experiments using riverbank-harvested macroplastics were set up in a laboratory environment, and on the banks of the Rhine River. Representative pixel selections of eleven lab-based images (n = 786,264 pixels) and two field-based images (n = 40,289 pixels) were used to analyse the differences between these environments. Next, classifier algorithms such as support vector machines (SVM), spectral angle mappers (SAM) and spectral information divergence (SID) were applied, because of their robustness to varying light conditions and high accuracies in mapping spectral similarities. Our results showed that SAM classifiers are most robust in separating plastic pixels from background elements. By applying lab-based data for plastic detection in field-based images, user accuracies for plastics to up to 93.6% (n = 8,370 plastic pixels) were attained. This study provides key fundamental insights in linking lab-based data to plastic detection in the field. With this paper we aim to contribute to the development of future spectral missions to detect and monitor plastic pollution in aquatic ecosystems.

Published: June 2022

This study examined the relationship between affect dynamics and cognitive factors and mood reactivity/recovery in a sample with on-going and previous depression. Participants (n = 62) completed up to five assessments of positive and negative affect per day for 13 days using an experience sampling method. Based on this, two indicators of affect dynamics (instability and inertia) were calculated for positive and negative affect. Three cognitive factors were measured: attentional functioning, interpretation bias, and attention bias. Mood reactivity and recovery were measured using a stress-induction procedure. Results showed that affect dynamics were not associated with mood reactivity. However, impaired mood recovery was associated with inertia (i.e., inflexibility) of positive affect. Inertia of positive affect was also associated with reduced positive interpretation and with reduced orienting efficiency. Results suggests that 1) reduced orienting efficiency and reduced positive interpretation bias are basic cognitive constituents for inflexible positive affect, and 2) that inflexible positive affect hampers stress-related mood recovery. In conclusion, affect dynamics may reflect an intermediate process explaining the link between cognitive factors and depression symptoms.
A Behavioral Perspective on the Decision to Seek Formal and Informal Financial Help
Authors: Jaroszewicz Ania
Published: June 2022

I use a behavioral economic lens to examine how people facing financial insecurity decide to seek financial help. Help can broadly be categorized as being either formal (provided by an organization or professional) or informal (provided by an individual acting in a personal capacity). I focus on one particularly vital type of financial help from each of these categories: from formal help, I examine social welfare program benefits; from informal help, I examine financial loans or gifts from friends and family. I begin by presenting a general framework that outlines how a person may decide to seek any type of financial help. In the framework, a person progresses through three stages as they make this choice: identifying whether that type of help is available to them, assessing how attractive it would be if they could get it without taking action, and estimating how costly the actions required to seek the help would be. I then apply the framework separately to the formal and informal help types, each time reviewing prior literature on factors that affect people’s (un)willingness to seek that help. Finally, I discuss policy implications, arguing that an understanding of both formal and informal help-seeking processes is crucial for informing policies intended to help financially vulnerable populations.

The Flickr frequency norms: what 17 years of images tagged online tell us about lexical processing
Authors: Petilli Marco A. , Guenther Fritz , Marelli Marco
Published: June 2022

Word frequency is one of the best predictors of language processing. Typically,word frequency norms are entirely based on natural-language text data, thusrepresenting what the literature typically refers to as purely linguistic experience. This study presents Flickr frequency norms as a novel word frequency measure from a domain-specific corpus inherently tied to extra-linguistic information: words used as image tags on social media. To obtain Flickr frequency measures, we exploited the photo-sharing platform Flickr Image (containing billions of photos) and extracted the number of uploaded images tagged with each of the words considered in the lexicon. Here we systematically examine the peculiarities of Flickr frequency norms and show that Flickr frequency is a hybrid metric, lying at the intersection between language and visual experience and with specific biases induced by being based on image-focused social media. Moreover, regression analyses indicate that Flickr frequency captures additional information beyond what is already encoded in existing norms of linguistic, sensorimotor, and affective experience. Therefore, these new norms capture aspects of language usage that are missing from traditional frequency measures: a portion of language usage capturing the interplay between language and vision, which, as this study demonstrates, has its own impact on word processing. The Flickr frequency norms are openly available on the Open Science Framework(https://osf.io/2zfs3/).
Feasibility and preliminary efficacy of digital interventions for depressive symptoms in working adults: a multi-arm randomised pilot trial
Authors: Taylor Rachael , Male Rhian , Economides Marcos , Bolton Heather , Cavanagh Kate
Published: June 2022

Background: Depressive symptoms are highly prevalent and have broad ranging negative implications. Digital interventions are increasingly available in a workplace context, but supporting evidence is limited. This study evaluated the feasibility, acceptability and preliminary efficacy of three digital interventions for depressive symptoms in a sample of UK based working adults experiencing subthreshold or mild to moderate symptoms. Methods: This was a parallel, multi-arm, pilot randomised controlled trial. Participants were allocated to one of three digital interventions or a wait list control group and had three weeks to complete 6-8 short self-guided sessions. Online assessments were conducted at weeks 0, 3 and 7. The interventions are available on the Unmind platform and draw on evidence based psychological therapies. Feasibility and acceptability were assessed using engagement and feedback data, efficacy outcomes were assessed using validated measures of mental health, wellbeing, and functioning, and linear mixed models.Results: 405 participants were randomised and 92% were retained. 97% initiated their allocated intervention and 67% completed all sessions. 81% rated the quality as excellent or good, and 80% were satisfied or very satisfied. All groups showed significant, maintained improvements in wellbeing, functioning, and depressive and anxiety symptoms vs control (p<0.05). Hedges g effect sizes were predominantly in the small to medium range. Limitations: This was a pilot study meaning efficacy findings require replication in a definitive trial. Conclusions: All interventions were feasible and acceptable, and findings indicate that their use can improve depressive symptoms, wellbeing and functioning. Pre-defined criteria for a definitive trial were met.
Perception of hate speech by the public and experts: Insights into predictors of perceived hate speech toward migrants
Authors: Papcunová Jana , Martončik Marcel , Fedáková Denisa , Kentoš Michal , Adamkovic Matus
Published: June 2022

Online hate speech is a matter of concern for social media platforms, regulators, researchers, and the public. Despite its widespread prevalence and contentious nature, little research has been done on the perception of hate speech and its psychosocial predictors. To address this gap, we conducted a study on the perception of hate speech towards migrants in online comments, analyzing the differences between a public group (NPublic = 649) and an expert group (NExperts = 27), and exploring the correlation between the proposed hate speech indicators and perceived hate speech in both groups. Additionally, we explored various predictors of hate speech perception, including demographic and psychological variables such as human values, prejudice, aggression, impulsiveness, social media behavior, attitudes toward migrants and migration, and trust in institutions. Our results show that the public and experts have differing sensitivities towards hate speech, with the expert group perceiving comments as more hateful and emotionally harmful compared to the general population, who tend to agree more with anti-migrant hateful comments. The proposed hate speech indicators, and especially their total score, have a strong correlation with both groups' perceptions of hate speech. Psychological predictors, such as the human values of universalism, tradition, security, and subjective social distance, were significant predictors of online hate speech sensitivity. Our findings emphasize the need for public and scholarly discussions, more robust educational policies, and intervention programs with specific measures to counter hate speech online.
Geographical Mobility and Occupational Achievement. A Longitudinal Analysis of South-to-North Internal Migration in Italy
Authors: Panichella Nazareno , Cantalini Stefano
Published: June 2022

Geographical mobility is a major driving force underlying demographic and social change, but surprisingly fewer studies have focused on how it influences occupational success and the intergenerational reproduction of social inequalities. This work studied the effect of internal mobility on occupational status in Italy, investigating if male and female occupational status benefited from South-to-North migration, and if the migration benefit or disadvantage changed according to the family status and the social class of origin.Empirical analyses are based on the Italian Household Longitudinal Survey by means of a set of fixed effects linear regression panel models combined with the coarsened exact matching (CEM). Results show that only men experience a migration benefit, whereas women experience a migration disadvantage, which increases when they move after the union formation and the transition to parenthood. Finally, the effect of geographical mobility differs according to the social class of origin only for men, since those coming from the upper classes experience a much higher migration benefit than those from the medium and the lower ones. We thus show that geographical mobility is an additional source of advantage for individuals from the upper classes, and its positive effect on male occupational success cumulates with the family-related one, increasing the social distances between individuals located in different social strata.
Divergent trajectories: Three dimensions of child poverty during the Great Recession in Ireland
Authors: Sprong Stefanie L. , Gibbons Ryan Alberto , Chzhen Yekaterina
Published: June 2022

While research has investigated the effects of the Great Recession on the Irish economy using economic indicators or cross-sectional household-level data, this research note applies group-based multi-trajectory modelling to provide a more nuanced approach. Using nationally representative, longitudinal data from the Growing Up in Ireland study, we analyse patterns in three common measures of economic well-being (financial strain, disposable income, and material deprivation) across Irish households in the period leading up to, during and after the Great Recession, and subsequently, break down the characteristics for each group of trajectories. We identify six distinct trajectory clusters, which all indicate declining income and increasing financial strain from the start to the height of the economic depression. However, trajectory groupings show that experiences were far from uniform, with previous economic well-being and demographic characteristics shaping the household experience. Implications for future research are discussed.

Authors: Kunwar Mala
Published: June 2022

Street children are spending the unhygienic life in street though they look happy to live in street. There is no exact data of street children in Nepal. Kathmandu is main city where more street children are seen begging in the street. The study was conducted to identify the sanitation and hygienic practice of street children living in the Kathmandu valley. There was total 234 street children selected for this study. The study found that majority of street children used to take path one time in every week. Similarly, majority of street children used the public toilet whereas 24% street children were using open space (open defecation) which was not good from the environmental perspective. The study also found that majority (58.12%) of street children used to take food from street shop. The food available in street shop is not hygienic because of the weak sanitation of surrounding environment. There is high chance of contamination due to dust pollution and use of untreated water for cooking food.

Ernest Weissmann’s Architectural and Planning Practices
Authors: Bjažić Klarin Tamara
Published: June 2022

Architect Ernest Weissmann (1903-1985) dedicated his career to improving the living conditions of the deprived population - before and immediately after World War II in Europe and the United States and, starting from the 1950s and owing to senior positions he held at the United Nations Department of Social Affairs [UN DESA], also in underdeveloped countries in Asia, Africa, and Latin America. The means by which he tried to achieve it were type projects flexible enough to respond to each individual case, education, teamwork, and self-help approach. The latter was thought to strengthen the local communities, their experts, resources, and production. Relying on the research on Weissmann’s pre-UN DESA career, this paper argues that Weissmann formulated most of his ideas, in particular self-help, and the above-mentioned methods, and put them into practice and an international perspective, before 1951 thanks, to his collaboration with Le Corbusier, the School of Public Health in Zagreb, the International Congress of Modern Architecture [CIAM], New York-based Structural Study Associates [SSA] group, Board of Warfare, and United Nations Relief and Rehabilitation Administration [UNRRA].

Published: June 2022

Acceptance sampling is the statistical method used to accept or reject product based on a random sample of the products. When done correctly, accepting sampling is effective for quality control. The acceptance number (c) and the sample size (n) are the basic objectives of any sampling plan. This study aims to construct two goal programing models for the determination of (n) and (c) with regard to four conflicting criteria. It applies non-linear integer goal programing techniques. The first model is assumed, a known and constant lot fraction defective, whereas the other model expected that it is a random variable having a Gamma prior distribution. The resulting two models were non-linear integer goal programing models. Consequently, these models could be worked out using any non-linear integer goal programing package.

The Quest for Gender Parity
Authors: Mushaben Joyce Marie
Published: June 2022

Given Angela Merkel’s long-standing reluctance to label herself a feminist, many scholars would find it hard to credit her with the increasingly “intersectional” composition of the Bundestag and the Landtage as of the 2021 elections. The last 16 years have nonetheless witnessed major shifts in German policies affecting the rights of women, persons with migration background, and lgbtqia community members. These developments have arguably contributed, directly and indirectly, to voters’ willingness to accept candidates with diverse backgrounds as capable of representing “the people’s interests” beyond the needs of their respective identity groups. This article considers multiple factors contributing to increasing diversity among German lawmakers at various levels, including policy shifts that have helped to reconfigure the political opportunity structure and thus the electoral landscape. It concludes with reflections on Merkel’s legacy, coupled with the role of generational change in “normalizing” diversity across the Berlin Republic.
Pathways to the Chancellorship
Authors: Helms Ludger
Published: June 2022

Olaf Scholz emerged as the Federal Republic’s ninth chancellor from a context marked by several “firsts,” including in particular the absence of an incumbent chancellor seeking re-election and a competition between three chancellor candidates. While few, if any, individual elements of Scholz’s profile were exceptional, the combination of elements was as unique as the wider political context. Echoing similar experiences from the Merkel years, the 2021 campaign and results suggest that in the German political context, advanced levels of personalization in the electoral arena are not dependent on any particular charisma of the competing lead candidates. In the end, Scholz, who managed to portray himself as a de facto incumbent seeking re-election, profited strongly from the perceived limitations and deficiencies of his contenders. A historical assessment of competitions for the chancellorship also reveals that the stakes for unsuccessful chancellor candidates have risen dramatically.
A Tale of Two Electorates?

Although the AfD is not, strictly speaking, an “eastern” party, its distinct electoral results in the two halves of Germany—underscored once again in the 2021 federal election—are something of a puzzle. In order to explain how and why the AfD performs better in eastern Germany than in western Germany, we analyze district-level results for the AfD vote, employing multiple regression models in order to find correlates with constituency vote share. We conclude that the only socio-demographic variable common to both eastern and western German AfD voters is their level of education. Significantly, we find that eastern AfD voters are both older and more economically secure than western German voters for the AfD.
Dr. Strangelove and the Psychology of Comic Distance
Authors: Hye-Knudsen Marc
Published: June 2022

In 1964, near the height of Cold War nuclear anxiety, millions of Americans flocked to movie theatres to see their own nuclear annihilation hilariously enacted for them in Stanley Kubrick’s Dr. Strangelove. How did Kubrick transform one of his time’s most pressing causes of psychological distress into a source of humorous pleasure? To answer this question, I offer a cognitive account of how comic distance works on film, building on research indicating humor to be an evolved response to benign violations. I show that Kubrick consistently optimized for psychological distance in Dr. Strangelove, comparing his narrative and stylistic choices to those of Sidney Lumet in Fail Safe, a contemporaneous film that plays the same essential story for drama instead of laughs.

Dyslipidemia is an important major issue that accounted for atherosclerosis and coronary heart disease. Therapy with synthetic drugs becomes a daily routine and can lead to multiple side effects. This makes herbal medicine often used as an additional treatment, one of which is coriander leaves (Coriandrum sativum L.). The goal of this research is to find out the lipid-lowering activity of coriander leaves ethanolic extract (CLEE) in male rats induced with the intake of a high-fat diet. The resulting data were analyzed by ANOVA (Analysis of Variance) then continued with the Post Hoc Tukey HSD test to see the differences between treatments. The result of this study shows that there were significant differences between the CLEE doses of 100, 200 and 400 mg/kg body weight. Based on the result show that CLEE has an effect in reducing levels of total cholesterol, LDL and triglycerides as well as increasing blood HDL levels of mice induced by a high-fat diet. Shown that of CLEE with affixed dose in 400 mg/kg BB has the best lipid-lowering agent among other treatments.

The polycystic ovarian syndrome is one of the most frequent gynecological disorders among reproductive-age women (PCOS). The polycystic ovarian disease is also known as Stein Leventhal syndrome or high androgen anovulation syndrome. It is a common endocrine illness marked by polycystic ovaries, chronic anovulation, and hyperandrogenism, which causes irregular menstrual periods, hirsutism, acne, and infertility. It is linked with a high risk of hypertension, hyperlipidemia, and types 2 diabetes all of which can contribute to strokes and cardiovascular disease. It must be diagnosed early in order to avoid future health complications. Because it is a treatable condition, it can be treated with either natural or allopathic medicines. Treatment with phytoestrogenic and non-estrogenic herbs such as Bauhinia variegata, Asparagus racemosus, Saraca asoca, Caesalpinia bonducella, Nigella sativa, Vitex negundo, Cinnamomum zeylanicum, and Symplocos racemosa which are effective and safe, polyherbal formulation is obtained from medicinal plants. The role of herbal medicine in the treatment of PCOS is the topic of this review.

COVID-19 had already spread throughout the world, and the novel coronavirus continues to pose a threat to the majority of countries. The current study uses the Susceptible-Exposed- Infectious-Recovered idea to assess the effects of social and economic factors, particularly the use of a medical mask, on the spread of COVID-19 in Andhra Pradesh. The influence of environmental parameters such as temperature and relative humidity on the number of COVID-19 cases per day is also investigated using numerical methods such as the Response surface methodology model. We provide the results of the curfew lockdown started by the Government of Andhra Pradesh for COVID19, as compared to a total lockdown scenario. As a result of the irresponsibility and crowded gatherings, the number of cases increases, stretching the mitigation period of the second wave COVID-19 spread, prolonging the curve's straightening. The Susceptible-Exposed- Infectious-Recovered model's predictions have been put to the test in a number of real-world scenarios. The fast spread of second-wave COVID-19 cases in Indian cities is similarly connected to temperature, as indicated by the well function of higher temperatures in breaking the lipid layer of coronavirus, but is severely inhibited by the critical component of social distancing, leading to uncertainty. As a result, it's critical to incorporate environmental factors into epidemiological models like Susceptible-ExposedInfectious-Recovered, as well as methodically design managed laboratory tests and modeling experiments to catch conclusive findings, assisting decision-makers and investors in developing comprehensive action plans to combat COVID-19's second wave

This study aims to utilize cassava and sugarcane bagasse to produce bioethanol as an environmentally-friendly alternative fuel. The raw materials were degraded by thermal hydrolysis at 145°C, 165°C, and 185°C, with the cassava to bagasse ratios at 1:2 and 1:3. The degraded material was then fermented using local yeast for 72 hours to produce bioethanol and finally, the resulting bioethanol was distilled at 85°C. The results showed that the process variables affect the yields and ethanol content produced. The best conditions were obtained in the sample with the cassava to bagasse ratio of 1:3, hydrolysis time of 120 minutes at a temperature of 185°C, and a fermentation time of 72 hours, from which the ethanol yield of 12.40% and ethanol content of 42.85% was obtained

The separator is a porous membrane and is the most important part of a lithium-ion battery. One viable alternative material used as the membrane is polypropylene (PP). This membrane has the advantages of being available in various sizes, well-controlled porosity, thermally and chemically stable, as well as low cost. Therefore, this study aims to determine the characteristics of the polypropylene membrane including the wettability value using a contact angle goniometer, surface morphology using SEM (Scanning Electron Microscopy), thermal properties using a thermogravimetric analyzer and thickness using a digital screw micrometer. The study was firstly conducted by preparing a PP membrane and the characteristics were then tested. The results showed that the contact angle was <90° indicating that the wetting value is good because of the fact that various membrane surfaces are wetted. The SEM test then indicated a homogeneous pore-shaped morphology. Furthermore, the differential scanning calorimetry (DSC) and the thermogravimetric analysis (TGA) tests showed that the PP membrane is capable of withstanding high temperatures up to 139°C, while the thickness test showed a value <25 m.
