Ethnic, Linguistic, and Religious Heterogeneity and Preferences for Public Goods and Redistribution in Latin America

One of the most prominent political-economic arguments is that heterogeneity undermines support for public goods and redistribution. Past research, however, has been mostly cross-sectional, used weak measures of heterogeneity, under-studied Latin America, and did not examine the multiple bases of heterogeneity. We assess negative (fractionalization and between-group inequality [BGI]) and positive (compensation) hypotheses with time-varying measures of ethnic, linguistic, and religious heterogeneity. We analyze four different preferences using up to six survey waves with over 200,000 Americas Barometer respondents across 24 Latin American and Caribbean countries. We estimate both fixed-effects models focusing on within-country variation and multilevel models focusing on between-country variation. Regardless of estimation technique, the prevailing pattern is statistical insignificance for both heterogeneity and BGI coefficients. The results largely contradict the fractionalization hypothesis, as only four of the 108 relevant heterogeneity coefficients are significantly negative. There is slightly more support for the BGI hypothesis, and especially ethnic BGI. Still, most BGI coefficients are insignificant and linguistic BGI is significantly positive in most models. The compensation hypothesis receives more support, as almost half of the heterogeneity coefficients are significantly positive. We conclude by cautioning against universal claims that heterogeneity undermines support for public goods and redistribution.

New three red-edge vegetation index (VI3RE) for crop seasonal LAI prediction using Sentinel-2 data

Leaf area index (LAI) serves as a pivotal parameter in crop monitoring, significantly impacting agricultural applications. Empirical models are one of the commonly used methods for estimating LAI, they are often dependent on vegetation indices (VIs), predominantly derived from low-to-moderate spatial resolution satellite sensors. A critical limitation of these VIs is their tendency to saturate at elevated LAI values. Additionally, the interplay between chlorophyll content (Cab), LAI, as well as average leaf inclination angle (ALA), particularly in reflectance spectra from red to red-edge regions, has been underexplored in past research. Based on Sentinel-2 satellite, with three red-edge bands and enhanced spatio-temporal resolution, this study introduced a new three red-edge vegetation index (VI3RE), comprising NDVI3RE and CI3RE, which leverages the unique spectral characteristics of these bands and related differential response to LAI and Cab variations. We investigated VI3RE’s efficacy through a threefold approach: firstly, by conducting sensitivity analyses using noise equivalent (NE)ΔLAI ((NE) ΔLAI=1.37 and 1.59 for NDVI3RE and CI3RE; (NE)ΔLAI = 1.75 – 3.25 for other VIs) and extended Fourier amplitude sensitivity test (EFAST) (the contribution of LAI: FOI > 30 % and TOI > 40 % for VI3RE; FOI ∼ 17 % − 28 % and TOI ∼ 25 % − 34 % for other VIs, except for NDVI with TOI ∼ 50 %), we demonstrated VI3RE’s heightened sensitivity to LAI and its improved capability for seasonal LAI estimation compared to other VIs. Secondly, by comprehensively considering the simplicity, interpretability, AIC and R2 values of various models, the linear regression model was selected for analyzing the relationships between LAI and various VIs. We established that VI3RE, particularly NDVI3RE, exhibits a robust correlation with LAI, thereby enhancing LAI estimation accuracy (R2 = 0.72, RMSE = 1.39). Lastly, we applied the LAI-VI regression models to generate crop LAI imageries throughout the growing season, subsequently validating by field measured LAI data. The results affirmed VI3RE’s superior performance in seasonal LAI estimation of crops, notably during peak growth and sowing phases. We conclude that the newly formulated VI3RE offers a universal, highly precise, and reliable model for LAI prediction across various crop types and phenological stages. However, the broader application of VI3RE may be limited, due to the three red-edge bands are not commonly found in most satellite platforms. In addition, some other aspects are not considered in this study, such as phenological information, meteorological factors, sampling strategies, etc., which should be meticulously considered in the future studies.

How consumers with hedonic (vs utilitarian) purchase motive use item-price (vs price-item) presentation order as a mechanism to justify their hedonic purchase

Purpose This study aims to investigate the moderating role of hedonic and utilitarian purchase motives for the presentation order effect. Although past research finds that presenting item first and price later (e.g. 70 items for $29) increases consumers’ purchase intention more than presenting the information in the opposite order (e.g. $29 for 70 items), the effect was mostly examined in a hedonic consumption context. This study examines whether the effect is applicable for hedonic purchases but is less applicable for utilitarian purchases, and why. Design/methodology/approach Seven experiments tested the moderating effect of purchase motives for the presentation order effect. Two serial mediation analyses were conducted to examine the underlying mechanism. Findings The “item-price” (vs “price-item”) order increases hedonic purchases, but not utilitarian purchases. Because consumers feel guilty about hedonic purchases, they engage in motivated information processing to perceive greater value from their hedonic purchase when item (benefit) information is presented first and price (cost) information is presented later. Perceiving greater value reduces guilt, which consequently increases hedonic purchases. In contrast, the order effect is not observed for utilitarian purchases that do not elicit guilt. When a price discount is offered, the order effect is reversed because actual savings justify hedonic purchases better than perceived savings resulting from motivated information processing. Practical implications When promoting hedonic products, marketers are recommended to present item information before price information, unless a price discount is offered, in which case the price should be presented first. Originality/value This research introduces a novel moderator for the presentation order effect and a novel underlying mechanism, driven by the motivation to alleviate guilt associated with hedonic purchases.

The Politicization of Climate Science: Media Consumption, Perceptions of Science and Scientists, and Support for Policy

Differential media treatment of climate change, including conservative media’s tendency to reject the anthropogenic climate change scientific consensus, has reinforced polarized perceptions of climate change. Studies have found differences in coverage patterns and in perceptions among those relying more heavily on conservative rather than liberal or moderate media. This scholarship has been limited by narrow measurements of media exposure, climate-related outcomes, and the mechanism of effects. We analyzed nationally representative US data (N = 1,181) using measures that included not only reported use of mainstream print, cable, and social media captured in past research, but also science programming, as well as far-right, alternative-health, and Christian media. On average, participants relied more heavily on centrist and liberal media, followed by Fox News and social media. The results corroborate findings associating exposure to centrist media with pro-climate attitudes, and conservative media, including Fox News with the opposite views. Use of far-right outlets was associated with the lowest levels of belief in anthropogenic climate change, perceptions of personal threat, and support for climate-friendly policy. Reliance on science media was associated with pro-climate views. Most associations were mediated via perceptions of science and scientists (using the Factors Associated with Self-Presentation of Science, FASS scale).

A Study on the Impacts of ‘Youtube’ as an Earning Platform on the Motivation Factors of Generation Z in the Workplace

Motivation’ has been proposed as one of the significant and effective methods for handling employee related issues in an organization since the 18th century, when Industrial Revolution (IR) 1.0 transformed the livelihood of people. Human resource practitioners and scholars, through their past studies and research from different eras of time, have identified various factors that motivate the employees. As humans are complex, various motivation theories have been developed by the researchers to understand people’s motivation better from different perspectives including their needs. Studies have indicated that various employee-related issues including employee turnover, organizational commitment, employee retention have been resolved through implementing the recommended motivation factors. This whole scenario was effective enough for the prevailing generations including Baby boomers, Gen X and Gen Y, as in most of the cases, issues arise from either the employees or the management where there was a gap of expectation fulfillment between these two parties only. The key question is, apart from these two parties, how if an external environment factor (refers to social media – YouTube in this study), leave an impact on the motivation factors of employees, especially the Gen Z, who is the first generation stepped onto the globally connected world. The focus of this study is centered on exploring the impacts of ‘YouTube’ as an earning platform on the motivation factors of Gen Z in their workplace.

'I only eat because I have to-to live': The impacts of dysphagia on quality of life from the perspectives of people with dysphagia, supporters of people with dysphagia and allied health professionals.

A recent literature review identified that past research has described the impacts of dysphagia on quality of life; but there is limited research on these impacts from the perspective of people with dysphagia, their supporters and allied health professionals. Recent qualitative research has provided details about these perspectives, but researchers have also called for verification of these findings with a larger group of participants. To expand upon the findings of the prior qualitative research on the views of people with dysphagia, supporters of people with dysphagia,and allied health professionals on the impacts of dysphagia and texture-modified food on quality of life. An online survey of adults with dysphagia (n = 30), supporters of people with dysphagia (n = 4) and allied health professionals (n = 18) was conducted between November 2021 and February 2022. Categorical questions were analysed descriptively and open-ended questions were analysed for content categories of meaning. Participants with dysphagia reported that dysphagia and texture-modified foods had a greater impact on their physical health than on their choice and control or social engagement. Supporters and allied health professionals viewed that dysphagia impacted the physical health and their choice and control of people with dysphagia. Across groups, participants considered that mealtime enjoyment, participation, and inclusion were influenced by the control the person had over their meals, the accessibility of the mealtime environment, and the attitudes of others. Dysphagia and its interventions negatively impact quality of life for people with dysphagia. People with dysphagia were the most affected by the physical impacts of dysphagia. Their perspectives contrasted with those of supporters and allied health professionals in some domains, highlighting the need for people with dysphagia to be included in research. Future research exploring how these perspectives are integrated into person-centred dysphagia management is warranted. What is already known on the subject Recent qualitative research has provided insights into the impacts of dysphagia on quality of life from the perspective of people with dysphagia, supporters of people with dysphagia, and allied health professionals. However, the small scale of these studies means that further research is needed with a larger group of people with dysphagia, supporters of people with dysphagia, and allied health professionals. What this paper adds to existing knowledge This paper verifies and extends upon the findings of prior qualitive research on the views of people with dysphagia, supporters of people with dysphagia, and allied health professionals on the impacts of dysphagia and its interventions on quality of life, participation, and inclusion. What are the potential or actual clinical implications of this work? This research shows the importance of supporters of people with dysphagia and allied health professionals discussing mealtime quality of life with the person with dysphagia so that their perspectives are considered in the mealtime decision-making process. Furthermore, people with dysphagia should be able to specify strategies they want to trial to enhance their mealtime participation and inclusion.

Directors’ exposure and social enterprise performance: does entrepreneurial mindset and financial resource availability matter?

PurposeBuilding on insights from the upper echelons theory and resource-based view (RBV), this study explains how directors’ exposure influences social enterprise performance through the mediating effect of entrepreneurial mindset, and the contingent role of financial resource availability.Design/methodology/approachThe study follows a quantitative approach. Data were gathered from a survey of 168 social enterprises (i.e. Community Interest Companies (CICs)) in the United Kingdom (UK), and covariance-based structural equation modelling (CB-SEM) was used to test the hypotheses.FindingsThe results show that directors’ exposure positively relates to social enterprise performance, and that the relationship is mediated by entrepreneurial mindset. Additionally, the findings reveal that financial resource availability moderates the indirect path between directors’ exposure and social enterprise performance such that the effect is more pronounced at high levels of financial resource availability.Originality/valueThis study is a pioneering attempt to uncover the linkage between directors’ exposure and social enterprise performance. Unlike past research, the study integrates the upper echelons theory and RBV to extend social enterprise research within the social entrepreneurship domain and provide important practical value for social enterprise practitioners.

From leadership to allegiance: the interplay of middle leadership, teacher job satisfaction and commitment in schools

PurposeMiddle leadership is difficult to define and fathom as these roles are fluid, adapting to the context of individual schools. However, little is known about the relationships among middle leadership, teacher commitment and job satisfaction in the field of education. The purpose of this paper is to propose a conceptual framework on the mediating role of teacher job satisfaction in the relationship between middle leadership and teacher commitment in schools based on past research, particularly in the context of schools.Design/methodology/approachA review of literature was undertaken to develop the conceptual framework.FindingsFindings suggested that middle leadership can positively influence teacher commitment via the mediating effect of teacher job satisfaction.Originality/valueThe value of this paper lies in understanding middle leadership as a salient factor in influencing teacher commitment via teacher job satisfaction. This paper’s framework lays a strong foundation for the expansion of the middle leadership knowledge base on middle leadership as well as for future theory development and debate.

The relationship between racial/ethnic identification and body ideal internalization, hair satisfaction, and skin tone satisfaction in black and black/white biracial women

Eurocentric physical characteristics, including a thin, tall physique, long straight hair, and fair skin, typify Western beauty standards. Past research indicates that for Black women, greater identification with one’s racial/ethnic culture may buffer against internalizing Eurocentric beauty standards, specifically the thin ideal. Black/White Biracial women often experience different appearance pressures from each of their racial identity’s sociocultural appearance ideals. Unfortunately, body image research is limited among Bi/Multiracial individuals. Participants were recruited online via Prime Panels, a high-quality data recruitment service provided by CloudResearch. Participants, M(SD)Age= 34.64 (12.85), self-reported their racial/ethnic identification, thin and thick/curvy ideal internalization, and hair and skin tone satisfaction. Using linear regression analyses, we assessed whether racial/ethnic identification buffered against monoracial Black (n = 317) and Black/White Biracial (n = 254) women’s thin ideal internalization. Additionally, we assessed whether stronger racial/ethnic identity was associated with stronger thick/curvy ideal internalization and hair and skin tone satisfaction. Supporting hypotheses, greater racial/ethnic identification was associated with higher thick/curvy ideal internalization and hair and skin tone satisfaction among both Black and Biracial women. Contrary to hypotheses, greater racial/ethnic identification was not associated with lower thin ideal internalization in either group. Our results stress the need to use racially and culturally sensitive measurements of body image.

From economic wealth to well-being: exploring the importance of happiness economy for sustainable development through systematic literature review

AbstractThe pursuit of happiness has been an essential goal of individuals and countries throughout history. In the past few years, researchers and academicians have developed a huge interest in the notion of a ‘happiness economy’ that aims to prioritize subjective well-being and life satisfaction over traditional economic indicators such as Gross Domestic Product (GDP). Over the past few years, many countries have adopted a happiness and well-being-oriented framework to re-design the welfare policies and assess environmental, social, economic, and sustainable progress. Such a policy framework focuses on human and planetary well-being instead of material growth and income. The present study offers a comprehensive summary of the existing studies on the subject, exploring how a happiness economy framework can help achieve sustainable development. For this purpose, a systematic literature review (SLR) summarised 257 research publications from 1995 to 2023. The review yielded five major thematic clusters, namely- (i) Going beyond GDP: Transition towards happiness economy, (ii) Rethinking growth for sustainability and ecological regeneration, (iii) Beyond money and happiness policy, (iv) Health, human capital and wellbeing and (v) Policy push for happiness economy. Furthermore, the study proposes future research directions to help researchers and policymakers build a happiness economy framework.

Pleasurable emotions and internalizing psychopathology: A multi-study examination of specificity and alternative explanations.

Past research has been inconclusive regarding the specificity of associations between discrete pleasurable emotions and internalizing symptoms. Contentment may be especially relevant to depression, whereas tranquillity may be especially relevant to worry. The goal of the current research was to clarify the mixed findings regarding the relation between pleasure deficits and internalizing psychopathology. Participants from three samples (Total N = 757) completed alternative measures of depression and pleasurable emotions. Participants in Study 1 also completed a measure of anticipatory and consummatory pleasure, and close peers to a subset of participants (N = 64) reported their perceptions of participants' depression severity. Participants in Studies 2 and 3 also completed a measure of worry. Across the three samples, contentment was significantly negatively associated with self-reported depression. This association could not be accounted for by tranquillity, cheerfulness, anticipatory pleasure, or consummatory pleasure. Contentment was also strongly negatively associated with peer-reported depression. Contentment was more strongly associated with depression than was cheerfulness. However, the strength of the association between contentment and depression relative to the strength of the association between tranquillity and depression depended on how contentment and depression were measured. Conversely, tranquillity was more strongly associated with worry than were contentment or cheerfulness. This study provides further evidence of the potential importance of the role of contentment in depression and tranquillity in worry. It may be useful to attend to contentment when assessing and treating depression and to attend to tranquillity when assessing and treating elevated worry.

Determining the plant-pollinator network in a culturally significant food and medicine garden in the Great Lakes region.

Understanding the interactions between plants and pollinators within a system can provide information about pollination requirements and the degree to which species contribute to floral reproductive success. Past research has focused largely on interactions within monocultured agricultural systems and only somewhat on wild pollination networks. This study focuses on the culturally significant Three Sisters Garden, which has been grown and tended by many Indigenous peoples for generations in the Great Lakes Region. Here, the plant-pollinator network of the traditional Three Sisters Garden with the inclusion of some additional culturally significant plants was mapped. Important visitors in this system included the common eastern bumble bee, Bombus impatiens Cresson (Hymenoptera: Apidae), and the hoary squash bee, Xenoglossa pruinosa (Say) (Hymenoptera: Apidae), as determined by their abundances and pollinator service index (PSI) values. Understanding the key pollinators in the Three Sisters Garden links biological diversity to cultural diversity through the pollination of culturally significant plants. Further, this information could be of use in supporting Indigenous food sovereignty by providing knowledge about which wild pollinators could be supported to increase fruit and seed set within the Three Sisters Garden. Our findings can also lead to more effective conservation of important wild pollinator species.

Moscas en La Leche: A Critical Evaluation of Hispanic-Serving Institution Campus Spaces Through Photovoice Methodology

ABSTRACT The Hispanic-Serving Institution designation is based on enrollment with the overarching goal to ensure specialized support for Hispanic students. Despite the intentional funding, some institutions reap the financial benefits while not bolstering resources and support for the Hispanic population, or at least without seeing positive outcomes. Past research has illustrated this through dollars spent per student by racial category and with analysis of student support programs. The purpose of this study is to investigate perceptions of Hispanic students on the physical space (i.e. facilities, classrooms, and art) of campuses, seeking to understand how students’ experiences at HSIs are influenced by their perception of physical space. In this study, we utilize photovoice methodology to conduct a single-institution case study approach, focusing on a four-year research university that has been designated as an HSI in the southwest United States. We find that some physical spaces like the library, football stadiums, and academic colleges on HSI campuses are causing distress amongst the Hispanic student population resulting in students purposefully avoiding important student support spaces.

Vertical distribution and tissue selection of Helicoverpa zea (Lepidoptera: Noctuidae) adult oviposition and neonates on soybean with an indeterminate or determinate growth habit.

Helicoverpa zea (Boddie) is a polyphagous pest that can cause serious damage to crops, including soybeans (Glycine max L.). In soybeans with both determinate and indeterminate growth habits, H. zea larvae are more commonly found on leaves compared to blooms, stems, and pods. Past research demonstrated that H. zea adults tend to oviposit near the upper part of the plant canopy in soybeans with a determinate growth habit. However, ovipositional selection on soybeans with an indeterminate growth habit is unknown. We hypothesized that H. zea would oviposit more uniformly throughout the canopy on indeterminate soybean growth habits due to more diffuse reproductive tissue. We planted field and greenhouse experiments with varieties sharing a similar relative maturity (2 maturity group [MG] 5.2 varieties and 2 MG 5.4/5.5 varieties) but with different growth habits. To test oviposition selection, adult H. zea females were allowed to oviposit under field and caged conditions. We counted the number of H. zea eggs and neonates on each plant tissue type from each of 3 equal parts in the plant canopy: upper, middle, and lower. In both experiments, eggs and neonates were most common on leaves at the top of the plant regardless of soybean growth habit. Consequently, ovipositional selection is likely independent of reproductive tissue availability, and patterns of oviposition through the canopy are similar in growth habits. An improved understanding of H. zea ecology in soybeans relative to indeterminate growth habits may improve recommendations for managing this significant pest of soybean.

Impact of Gwadar Deep Seaport Development under CPEC on Poverty Alleviation in Gwadar City

The purpose of this study is to investigate the impact of the deep seaport development project under the China-Pakistan Economic Corridor (CPEC) on poverty alleviation in Gwadar city. A review of past research highlights the feasibility of similar projects that have been initiated in other countries and their positive outcomes for regional economies. Previous literature indicates that port development projects enhance local economic growth and help reduce poverty in the region. This study uses three key indicators to measure poverty: education level, health facilities, and living standards. The statistical analysis reveals that improvements in these three indicators have led to a decrease in poverty levels in the region. Under CPEC, various development projects have been launched across the country. However, several issues can limit the benefits of these projects, such as political interference, pressure from vested interest groups, and adverse effects on the natural environment. The study recommends that improving regional connectivity and fostering social interaction among inhabitants are crucial for maximizing the benefits of these development projects and effectively alleviating poverty.

Parameterization of H2SO4 and organic contributions to volatile PM in aircraft plumes at ground idle.

Volatile Particulate Matter (vPM) emissions are challenging to measure and quantify, since they are not present in the condensed form at the engine exit plane and they evolve to first form in the aircraft plume and then continue to grow and change as they mix and dilute in the ambient atmosphere. To better understand the issues associated with the initial formation and growth of vPM, a modeling study has been undertaken to examine several key parameters that affect the formation and properties of the vPM that is created in the initial cooling and dilution of the aircraft exhaust. A modeling tool (Aerosol Dynamic Simulation Code, ADSC) that was developed and enhanced over a series of past research projects supported by NASA, DoD's SERDP/ESTCP, and FAA (Wong et al. 2010, 2014, 2015) was used to perform a parametric analysis of vPM. The parameters of fuel sulfur content (FSC), emitted condensable hydrocarbon (HC) concentrations, and the species profile of the HCs were used to construct a computational matrix that framed a wide range of expected parameter values. This computational matrix was executed for two representative commercial aircraft engines at ground idle and results were obtained for distances of 250 m and 1000 m downstream. From prior results, the most significant vPM emissions occur at the lowest power settings, so an engine power condition of 7% rated thrust was used. A primary goal of the parametric study is to develop an updated vPM modeling methodology and also to help interpret data collected in experimental campaigns. The parameterization proposed here allows the vPM emission composition and particle numbers to be estimated in greater detail than current methods. The aim is to provide additional understanding on how the vPM properties vary with fuel and engine parameters to increase the utility of vPM predictions.Implications: Volatile ParticulateMatter (vPM) is an important contribution to the total PM emitted by aviationengines. While vPM is not currently a part of engine emissions certificationregulations, vPM is used in aviation environmental impact assessments and forair quality modeling in and around airports. Current methods in use, such asFOA (Wayson et al. 2009), were developed before many recent advances inexperimental data acquisition and in understanding of vPM processes. Theparameterization proposed here allows the vPM emission composition and particlenumbers to be estimated in greater detail than current methods. These estimatescan be used to develop inventories and provide a better estimate of total PMemission for most aviation engines. Its use in international regulatory toolscan inform possible future regulatory actions regarding vPM.

Agree to agree: correcting acquiescence bias in the case of fully unbalanced scales with application to UK measurements of political beliefs

AbstractA methodologically important area in political science is measuring the ideology of voters. This task can be difficult, and researchers often rely on ‘off the shelf’ datasets. Many of these datasets contain unbalanced Likert scales, which risk acquiescence bias. This paper proposes a strategy for dealing with this issue. I first demonstrate using two comparable datasets from the UK how unbalanced scales produce distorted distributions and can affect regression results. Then, building on past research that utilises factor analysis to eliminate the influence of acquiescence bias, I demonstrate how researchers can utilise a person intercept confirmatory factor analysis model to obtain factor scores corrected for acquiescence in the case of fully unbalanced scales. I conclude with practical recommendations for researchers and survey designers moving forward.

Engineering Approach to Explore Language Reflecting Well-Being

Although well-being is helpful in measuring the state of society from various perspectives, past research has been limited to (1) questionnaire surveys, which make it difficult to target a large number of people, and (2) the major indices focus on individual factors and do not incorporate group factors. To tackle these issues, we collected daily reports from the company employees that included text, their individual subjective well-being, and team subjective well-being. By using the collected data, we constructed a well-being estimation model based on the Large Language Model and examined an indicator called ``sharedness index'', as a state of the team that influences an individual well-being, measured using both score- and text-based methods.
