Increasing inequalities in mortality among individuals with a foreign background in Sweden

Abstract Background Previous research indicates that migrants in high-income destination countries not only experience a mortality advantage but also demonstrate lower or absent socioeconomic inequalities in mortality compared to the general native population. Yet the extent to which an income mortality gradient may also be evident among the descendants of migrants has been largely unexamined. Existing evidence has revealed that descendants of migrants face mortality risks higher than both migrants and their native-born peers. Methods This study utilizes longitudinal population registries covering the entire registered population of Sweden from 2004 to 2016. The study population comprises individuals aged 25 to 64, employing an open cohort design. Using Poisson regression, we examine the relationship between income rank position and cause-specific mortality among native-origin Swedes and eight nativity groups based on individuals’ country/region of birth, age of migration or parental origin. Results While foreign-born individuals who migrated as adults exhibited lower inequalities in all-cause mortality compared to native-origin Swedes, descendants of immigrants, particularly those with non-European backgrounds, show larger inequalities. Examination of specific causes of mortality revealed that external causes, notably accidents and assaults, account for increased disparities among non-European foreign-born men who migrated during childhood and male descendants of immigrants with non-European backgrounds. Conclusions Income-related inequalities in mortality are less pronounced among migrants compared to the native-born majority population in Sweden and tend to be higher among descendants of migrants, depending on gender and parental origin. The analysis highlights the role of external causes of mortality in shaping these inequalities, indicating that income disadvantages, augmented by a migrant background during upbringing, amplify specific health risks within these groups. Key messages • The study reveals lower mortality inequalities among migrant adults but a higher magnitude of inequalities among male descendants of immigrants, especially with non-European backgrounds. • Income disparities, combined with migrant backgrounds, amplify health risks among descendants of migrants in Sweden, underscoring the need for tackling social inequalities.

Resource productivity and determinants of technical efficiency among cassava farmers’ in north central, Nigeria

This research analyzed resource productivity and determinants of technical efficiency among cassava farmers in North Central, Nigeria. This research employed a multi-stage sampling technique. Primary data were used based on a well-designed questionnaire. Inferential and descriptive statistics were employed for data analysis. The results of resource productivity of inputs show that cassava cuttings and fertilizer have the highest and lowest elasticities, respectively. The mean-TE (Technical Efficiency) score of 74% (0.74) indicates that an average smallholder cassava producer in the sample needs about 26% (0.26) additional inputs to get to the frontier. In the TE components, the coefficients of labour, and fertilizers are significant different from zero at 1% probability level. The coefficients of agrochemicals, land inputs are significantly different from zero at 5% probability level, while the coefficient of cassava cuttings are significant different from zero at 10% probability level. In the TIE (technical inefficiency), component the coefficients of age, credit received, members of cooperatives are significant different from zero at 1% probability level. The policy formulations should be directed towards considering technological substitutions and mechanized agriculture. Excessive labour supply, characteristics of the developing agriculture in sub-Saharan Africa, could be pushed into the secondary sector of the Nigerian economy such as the cassava processing industry, therefore generating income, employment and maintaining Nigeria in the first (1st) position in the world ranking in term of cassava output. Also, it is recommended that improved cuttings, agrochemicals, and fertilizers should be made available to cassava farmers at appropriate time to increase productivity. Furthermore, credit should be made available to cassava farmers at a single digit interest rate, devoid of cumbersome administrative procedures. Keywords: Resource productivity, technical efficiency, cassava farmers, stochastic frontier model, Nigeria

Native Faculty in Library and Information Science, 1990–2022

We assessed the representation of Native faculty in LIS programs from 1990 to 2022. We comparative representation in LIS against trends in postsecondary education in the U.S. We utilized ALISE and federal data sources. We found that in both fields, Native faculty held lower ranking positions, predominantly as assistant professors. We also revealed that the quantity of Native LIS faculty was extremely low throughout the period assessed, with the possibility of a very few outlier LIS programs driving national statistics. Our study suggests that factors affecting representation of Native faculty in LIS might be similar to those in postsecondary education.

Toward Centrality Evaluation of Yearning Symptoms for Prolonged Grief Disorder: A Cross-Cultural Approach

Background: The new ICD-11 diagnosis of prolonged grief disorder (PGD) is characterized by the prominent role of yearning as hallmark symptom. A secondary analysis of eight international datasets on PGD was conducted to evaluate this assumption. Additionally, cross-cultural comparison explored whether the centrality of yearning differs across world regions. Methods: Primary studies originated from German-speaking countries (n = 4 samples), other European countries and Israel (n = 3 samples), as well as China (n = 1 samples). Different PGD measures were used, including yearning and longing as symptoms. For the centrality assessment of yearning, PGD symptoms were ranked by their factor loadings from confirmatory factor analyses, followed by statistical testing to determine significant differences between yearning and other symptoms of PGD in their factor loading estimates. Subsequently, ranking positions of yearning in three world regions (German-speaking, other Europe-Israel, and China) were compared. Finally, proxy thresholds for individuals at high-risk states for PGD were defined for the different datasets, and sensitivity-specificity analyses of yearning were performed. Results: Yearning was ranked high in five out of 12 models tested. In the German-speaking region, it was predominantly ranked among the most central symptoms; in the other Europe-Israel region as well as China, it tended to fall into the middle or lower rankings of symptom centrality. Sensitivity values were consistently high, while specificity values indicated moderate levels. Discussion: In line with previous research on the general outcomes of grief, the present study showed that yearning may be subject to a culture-specific distribution. Other central symptoms such as feeling as if a part of oneself died have also been shown to potentially play a central role in PGD across world regions. On the other hand, the sensitivity-specificity analyses revealed that yearning can be considered a significant (diagnostically highly sensitive) symptom for individuals in high-risk states for PGD, although it has only moderate specificity (i.e., its absence does not necessarily indicate individuals experiencing normative grief). Nonetheless, a culture-sensitive approach to psychopathology should consider the cultural differences in the centrality of this symptom group. More research is needed to better understand the role of yearning and its determinants across world regions.

Land use transformations in the Brazilian Savanna: A decade of soil erosion and runoff measurements

Changes in land cover and land use (LULC) are one of the main drivers of erosion and runoff. How ever, most research has relied on short-term observations and only focused on one or two land cover types. We investigated the long-term trade-off between common agricultural land covers (sugarcane, pasture, and soybean), runoff, and soil loss rates. We compared these to native forest (wooded Cerrado) and bare soil. The field observations were done in 100 m2 experimental plots in Brazil maintained during the past 10 years. The paper provides three main contributions: (1) long-term runoff and soil loss rates of plots under different LULCs, (2) comparison of runoff, soil loss, and pedological characteristics between plots constructed 10 years apart, and (3) analysis of the trade-off between different LULCs. When ranking land covers based on runoff and soil loss rates, there is a shift in ranking positions, making it difficult to determine which one is more environmentally harmful. However, it is evident that whatever agricultural practice is used, there is a significant impact when compared to native forest. For example, the area converted to pasture resulted in almost 20 times higher runoff, while conversion to sugarcane resulted in 5 times higher soil loss. Not only land cover plays a major influencing factor, but also weathering exposing time. Areas under the same land cover and environmental conditions had different rates of soil loss and runoff due to long-term exposure effects such as soil crusting. Our findings have high relevance for the hydrological and agricultural community by demonstrating (i) the magnitude of trade-off in terms of soil loss and runoff due to land cover changes and (ii) that soil loss should not be assumed to be a linear process over time, as it is commonly assumed.

Climbing university rankings under resources constraints: a combined approach integrating DEA and directed Louvain community detection

AbstractOver recent years, scholarly interest in universities’ allocation and effective utilisation of financial resources has been growing. When used efficiently, financial resources may improve universities’ quality of research and teaching, and therefore their positions in world university rankings. However, despite the relevance of financial efficiency to university placement in academic rankings, universities’ total available financial resources appear much more significant. In the present study, we propose an innovative methodology to determine realistic ranking targets for individual universities, based on their available financial resources. In particular, we combine data envelopment analysis, as developed by Banker et al. (Manag Sci 30(9):1078–1092, 1984), and a directed Louvain community detection algorithm to examine 318 universities across five countries, considering their ARWU scores alongside key financial indicators (i.e., long-term physical capital, total operating revenues). We identify clusters of universities with similar financial profiles and corresponding ARWU scores, as well as universities that have optimised their use of financial resources, representing benchmarks for similar universities to emulate. The approach is subsequently applied to Italian universities, as a specific national case. The findings may be useful for policy makers and university managers seeking reliable strategies for climbing academic rankings, particularly in countries with limited public investment in higher education.

Evaluation of University Ranking System to Propose a Model for Bangladeshi Universities

This study investigates and compares various university ranking systems, particularly considering the unique situation of Bangladesh. With the rise of globalization and emphasis on research in the knowledge-based economy, university rankings have gained significant attention. However, different organizations use diverse criteria and methodologies, leading to discrepancies in ranking positions. This research employed a two-phase approach. The first phase involved a systematic literature review focusing on globally used indicators and methodologies for university rankings. This phase revealed that research-related indicators hold the highest weightage (67.93%) in most ranking systems. Subsequently, the second phase utilized active ranking algorithms to explore the findings from the first phase. The study concludes that research output significantly influences a university's ranking and competitiveness globally. Considering Bangladesh's lower publication volume compared to other nations, adopting a ranking system like QS or THEWUR could be beneficial. This system aligns with the global focus on research output and could incentivize research efforts within Bangladeshi universities.

Falling Fortunes: The Contingent and Asymmetric Effect of Rankings on Organizational Outcomes

As rankings of organizations have proliferated in recent decades, much research has focused on organizational efforts to maintain a high position in rankings. A common theme in this literature is that changes in rank affect evaluations by external audiences and, consequently, organizational outcomes. Yet, accumulating evidence suggests that rankings sometimes have little effect on audience assessments and organizational outcomes, a finding that calls into question the power of rankings. Instead of asking whether rankings matter, this study adopts a contingency approach and investigates when rankings matter. I develop theory about contextual and organizational factors that shape the salience and information value of shifts in rankings: the direction of the change, the availability of information from other intermediaries, the sophistication of the audience, and the focal organization’s previous ranking position. Panel data analysis and a natural experiment focused on the Fortune 500 rankings support this theory. This article provides a framework to help scholars understand the contingent and asymmetric consequences of rankings on organizational outcomes, with implications for research on evaluation systems.

Performance trajectories of Italian professional cyclists: an analysis of the influence of youth performance on professional success

ABSTRACT The aim of the study was to analyse individual performance trajectories of professional (PRO) Italian cyclists across their careers. It sought to compare the performance progression of successful and unsuccessful PRO cyclists, analyse the best predictors of success in PRO cyclists and explore whether the relative age effect (RAE) influences PRO success. The national ranking positions gathered in the youth (U19 and elite/U23) and the PRO categories were retrieved for every year of competition of 81 PRO Italian cyclists and retrospectively analysed. Participants were divided in successful and unsuccessful, depending on whether they reached at least once the top 400 positions in the PRO ranking or not. Successful PRO cyclists display better youth ranking positions and tend to spend less time in youth categories, transition to the PRO category at an earlier age, reach their best PRO ranking at an older age compared to unsuccessful PRO cyclists. The best youth ranking, the age of the best PRO ranking and the years spent in youth categories are all predictors of PRO success. For every additional year spent in youth categories, there are 50.8% less odds of becoming a successful PRO cyclist. RAE does not affect Italian cyclists’ PRO success.

Are the Positions in the Word Ranking of Competitive Alpine Skiers Explainable by Prominent Polymorphisms in Regulatory Genes of Mechanical and Metabolic Muscle Functioning?

ABSTRACT Background: The success of competitive alpine skiers with respective to their world ranking (WR) positions might be associated with prominent gene polymorphisms. Methods: Twenty-six competitive alpine skiers were followed from 2015 to 2019 for their WR positions (FIS-ranking). Using PCR, the genotypes of ACE-I/D, TNC, ACTN3, and PTK2 were identified. The correlations between the discipline-specific WR position (slalom—SL, giant slalom—GS, super G—SG, downhill—DH, and alpine combined—AC) and gene polymorphisms were analyzed concerning an influence with multivariate regression models. Results: The WR position and the ACE gene as well as the copy number of the ACE I-allele exhibited reciprocal relationships for speed specialists (SG and DH) but not for technical specialists (SL and GS). Similarly, the gene polymorphisms ACTN3 and (partly) PTK2 were associated with the WR position in disciplines characterized by a high number of turns (technical specialists—SL and GS) and speed (speed-specialists—SG and DH), respectively. Conclusions: Our findings emphasize the contributions of aerobic and cardiovascular metabolism in fueling muscle work and recovering from muscle fatigue for competitive success in slalom-driven skiing disciplines and highlight the contributions of sequence variants in the genes ACE, TNC, and ACTN3.

La influencia de las autocitaciones en las decisiones editoriales a partir de la simulación de rankings de revistas

The manipulation of the Journal Impact Factor (JIF) through editorial decisions that increase self-citations has been empirically observed in recent studies, sparking discussions on how to avoid such practices. This study aims to verify whether a policy of removing self-citations from the JIF calculation is enough to eliminate incentives for manipulation. We introduce an agent-based model of the academic social network formed by journals to test this hypothesis. We model journals as rational agents seeking to gain positions in the JIF ranking. The model was implemented in NetLogo and calibrated using data from the SCIMago Journal Ranking. Simulation results demonstrate that the model is capable of reproducing patterns observed in empirical networks and that the removal of self-citations can significantly reduce the adoption of manipulation strategies (e.g., reduction from 90% to 30%). This study contributes to understanding the role of self-citations in the JIF and provides tools for developing policies that promote scientific integrity.

Research performance of higher education institutions in Türkiye: 1980–2022

In recent years, there has been a growing interest in the measurement of research performance. These studies evaluate a country or groups of countries according to their research performance and make some inferences to improve their performance. This study analyses the research performance of Turkish higher education, which aims for higher positions in international rankings, in the context of publication productivity, impact and collaboration with data based on Web of Science and comprehensive indicators for the years 1980–2022. In addition, research area-based analyses were also made. In this way, by presenting Türkiye’s performance from past to present in a comprehensive manner, rich information has been provided to policy makers, decision makers, and practical implications have been made for the improvement of performance. According to the results of the study, Türkiye has been faced with low productivity for many years. Both the area-based analyses and the results for the overall publication impact revealed that although there has been an increase in publication impact in recent years, Türkiye’s publication impact has performed below the world average in all years examined. The results indicated that Turkish higher education has some problems in terms of quality. As for research collaboration, the results showed that Türkiye gives more importance to domestic collaborative publications rather than international collaboration, while industry collaboration continues to remain in the background. Based on the results of the study, practical implications for policy makers and decision makers were made.

Economic Determinants of Smart and Sustainable Urban Development: What Answers Does the Cities in Motion Index Give?

The goal of the article is to determine which components of sustainable and smart development of urban areas are the most important for the economy of a city. For this, regression, cluster and discriminant analysis are applied, using the data of the ranking positions of 180 cities of the world according to the Cities in Motion Index (CIMI) and its components for 2022. The Stata and Statgraphics 19 software packages are used for the calculations. The statistical significance of the input data is confirmed using descriptive statistics, and the normality of the data distribution was determined according to the Shapiro-Wilk test. A regression analysis (based on the least squares method) of the influence of the integral value of CIMI and its components (Human capital, Social cohesion, Environment, Governance, Urban planning, International profile, Technology, Mobility and Transportation) on its first component – Economy, is carried out. It testifies that only four indicators have a statistically significant impact: Cities in Motion, Environment, Urban planning, and International profile. Multiple regression, constructed using the strict screening procedure, confirms these findings; and discriminant analysis proves that the regression equation coefficients is used to predict the Economy variable. Analysis of Spearman’s and Kendall’s correlation matrices prove a close relationship between the Economy, Human capital, Governance, and Cities in motion; direct dependence between Cities in motion and such indicators as Technology, Urban planning, and International profile; average direct connection between Economy, Social cohesion and Mobility and transportation. Cluster analysis using the k-means method in the R Studio software environment made it possible to distinguish eight clusters of cities according to their ranking positions in relation to various parameters of the CIMI index (their number was calculated according to the Sturgess formula, and the optimality of their number is confirmed by the agglomeration scheme according to the Ward method). For the cities of the first cluster (17 cities, 9.44% of the total number analyzed, mostly world capitals), Cities in motion has the greatest impact on the Economy component, while Mobility and Transportation has a lesser impact; for the cities of the second cluster (23 cities, 12.78%, mostly large cities of the United States and China) it is Technology that has the greatest impact; for cities of the third cluster (35 cities, 19.44%, primarily powerful regional centers)it is Cities in motion, International profile, Mobility and transportation, Social cohesion, and Urban planning; for clusters four (9 cities, 5%) and five (6 cities, 3.33%), the regressions are not significant, so these clusters require further study for each city separately; for the cities of the sixth cluster (33 cities, 18, 33%, mostly developed European cities) the most important are Cities In motion, Environment, Governance, Mobility and transportation, Social cohesion, and Urban planning; for the cities of the seventh cluster (10 cities, 5.56%) – Human capital, Social cohesion, and Technology; for cities in the eighth cluster (47 cities, 26.11%, mostly cities facing economic obstacles to their development) – Cities in motion, Environment, Technology, and Urban planning. The discriminant analysis shows that the Environment indicator has the greatest impact on the division of clusters into groups.

Social network strategies to distribute HIV self-testing kits: a global systematic review and network meta-analysis.

Social network strategies, in which social networks are utilized to influence individuals or communities, are increasingly being used to deliver human immunodeficiency virus (HIV) interventions to key populations. We summarized and critically assessed existing research on the effectiveness of social network strategies in promoting HIV self-testing (HIVST). Using search terms related to social network interventions and HIVST, we searched five databases for trials published between 1st January 2010 and 30th June 2023. Outcomes included uptake of HIV testing, HIV prevalence and linkage to antiretroviral therapy (ART) or HIV care. We used network meta-analysis to assess the uptake of HIV testing through social network strategies compared with control methods. A pairwise meta-analysis of studies with a comparison arm that reported outcomes was performed to assess relative risks (RR) and their corresponding 95% confidence intervals (CI). Among the 4496 manuscripts identified, 39 studies fulfilled the inclusion criteria, including one quasi-experimental study, 22 randomized controlled trials and 16 observational studies. Networks HIVST testing was organized by peers (distributed to known peers, 15 studies), partners (distributed to their sexual partners, 16 studies) and peer educators (distributed to unknown peers, 8 studies). Among social networks, simulating the possibilities of ranking position, peer distribution had the highest uptake of HIV testing (84% probability), followed by partner distribution (80% probability) and peer educator distribution (74% probability). Pairwise meta-analysis showed that peer distribution (RR 2.29, 95% CI 1.54-3.39, 5 studies) and partner distribution (RR 1.76, 95% CI 1.50-2.07, 10 studies) also increased the probability of detecting HIV reactivity during testing within the key population when compared to the control. All of the three social network distribution strategies enhanced the uptake of HIV testing compared to standard facility-based testing. Linkage to ART or HIV care remained comparable to facility-based testing across the three HIVST distribution strategies. Network-based HIVST distribution is considered effective in augmenting HIV testing rates and reaching marginalized populations compared to facility-based testing. These strategies can be integrated with the existing HIV care services, to fill the testing gap among key populations globally. CRD42022361782.

SOYBEAN CULTURE AND ITS ROLE IN MODERN GLOBAL AND NATIONAL АGRICULTURAL PRODUCTION

The research objective is to analyze the dynamics of soybean cultivation areas, its yield, and the gross harvest of seeds globally and in Ukraine over an extended period, and to establish Ukraines position in the global production of the crop under the conditions of military aggression by the Russian Federation. Methods. The research employed comparative methods, synthesis, and the analysis of digital data. Results. The analysis of statistical data and contemporary scientific publications enabled the examination of the dynamics of soybean cultivation areas and its yield both globally and in Ukraine, as well as establishing Ukraines position in the global production of the crop seeds. The regions in Ukraine with the maximum cultivated area of soybeans, yield, and gross harvest of its seeds were identified. Conclusions. In 2023, the global leaders in soybean production were Brazil, the United States, and Argentina, which collectively produced 318.344 million tons, accounting for 81% of total global production. Ukraine held the ninth position in the global ranking with a 1% share of total soy production, amounting to 5.2 million tons. In Ukraine, the largest soybean cultivation areas in 2023 were in Poltava (214.3 thousand hectares), Khmelnytskyi (210.6 thousand hectares), Zhytomyr (147.4 thousand hectares), Vinnytsia (139.9 thousand hectares), and Kyiv (138.7 thousand hectares) regions, together accounting for 46.4% of the soy cultivation areas in the country. The highest soybean yields in 2023 were recorded in the Ivano-Frankivsk region at 3.37 tons/ha, Lviv at 3.17 tons/ha, Ternopil at 3.01 tons/ha, and Zakarpattia at 2.93 tons/ha, with the national average being 2.59 tons/ha.

К вопросу об эволюции территориальной структуры ВВП

Due to the extreme diversity of economic conditions, the level of interregional differences in Russia is unique. The extent of these differences is usually measured by traditional indicators of variation based on per capita GRP indicators. However, while the movement of the coefficient of variation, for example, reflects the systemic properties of the object under study, it may not capture structural spatial shifts. But it is precisely these shifts, if they are stable, that are of particular interest both as a subject of scientific research and as an object of management by authorities. The main question posed in the article is the following: Is there a connection between the level of economic development of a region and its “propensity” for structural displacement? Or in other words: how stable is the territory’s position in the interregional ranking of per capita GRP indicators, does it depend on the value of per capita GRP? It turns out that noticeable structural shifts (predominant growth or increasingly lagging behind the per capita GRP of the region relative to the national average) are the prerogative, first of all, of territories with a level of per capita GDP close to the average.

Developing Methods for Assessing the Social Impact of Scientific Study

In many countries, there is a need to introduce new or improved existing methods for evaluating the social impact of scientific study on the environment of scientific institutions and universities. It is necessary to apply complex methodological solutions that should consider using research results by the non-academic world. The results of this evaluation are often crucial for building a university's position in national and international rankings. They may influence decisions regarding the level of financing of scientific institutions and the distribution of public funds for subsidies, scholarships, and financial aid concerning research grants. The paper aims to review existing methodological solutions and identify key trends in developing methods for assessing the social impact of scientific study. In this case, the scope of the research was limited to evaluating the study conducted within the field of social sciences. Running such assessments is more complicated than for the technical domain, for which more easily measurable bibliometric indicators and patents are available. The research used quantitative bibliometric analyzes based on the Scopus citation database, supported by bibliometric network analyzes. The results enable the identification of crucial methodological trends, potential opportunities and directions for developing research conducive to improving methods for assessing the social impact of study. Providing an overview of existing knowledge in this field creates a foundation for continuing further research.

Personalidad GRIT y talento deportivo en atletas de taekwondo de élite

Introduction: It has been shown that GRIT is related to success in various areas of life, including sports performance. Objective: To determine the relationship between GRIT personality and sports talent in elite taekwondo athletes. Methodology: A quantitative study with a quasi-experimental observational design and a descriptive-correlational scope was conducted with elite taekwondo athletes participating in sports camps associated with the National Taekwondo Organization in the United States (USAT) during the year 2023. GRIT personality was assessed using the Grit Scale, while sports talent was determined based on the national ranking position in the USAT. Results: After conducting correlation analysis using Pearson's r test, negative relationships were identified in the core variables (-0.009, p=0.847; 0.004, p=0.928; 0.011, p=0.809); however, these relationships were not statistically significant. The athletes' GRIT scores had a median of 4.00, suggesting that this population exhibits high levels of perseverance according to the GRIT scale. Conclusion: No statistically significant relationship was found between GRIT personality and sports talent in taekwondo athletes. These results support the notion that GRIT personality may not be a strong predictor of sports talent. However, the possibility of a relationship between these two concepts cannot be completely ruled out, as evidence supporting this association has been found.

Exploring the effects of quality signals on search advertising performance: the moderating role of keyword attributes

PurposeIn online exchange platforms' sponsored search advertising, the array of product quality signals within a keyword search results list plays a crucial role in shaping buyers' purchasing decisions. This research seeks to explore the impact of various quality signals – namely, ranking position, seller reputation and product price – on ad clicks. Additionally, it examines the role of keyword attributes, such as specificity and popularity, in modulating the effects of these quality signals on advertising clicks.Design/methodology/approachA total of 5,763 effective data points were collected from a leading B2B electronic platform company, and we employed negative binomial regression with Heckman correction methods to test the hypotheses.FindingsThe results indicate that in online exchange platforms, search ad clicks are significantly and positively affected by displayed signals such as ranking position, seller reputation and product price information. Notably, a U-shaped relationship emerges between product price and ad clicks. Furthermore, keyword specificity and popularity distinctly moderate the impact of these displayed signals on ad clicks within online exchange platforms.Originality/valueThis paper addresses the gap in existing research on search advertising by methodically analyzing the impact of various signals displayed in search results and how keyword attributes moderate ad clicks, all through a signaling theory lens.
