Impacts of Inundation on Bird Assemblages in Forests in and around a Hydrodam in Terengganu, Malaysia

Despite the increasing numbers of hydrodam worldwide, only a handful of studies evaluated their impacts on biodiversity. Compared to terrestrial animals, birds were thought to be less affected by inundation process, following impoundment. At the Hulu Terengganu Hydroelectric Dam in Peninsular Malaysia, our study compared species assemblages and diversity of birds within the dam area (i.e. the dam reservoir and catchment area) after recent logging and inundation in relation to a nearby forest logged 30 years ago. Using point count and mist-netting techniques, we recorded a total of 64 species (Shannon Index (H’) = 3.827) in the dam area and 91 species (H’=3.99) in historically-logged forests. Insectivore species richness was significantly higher in the historically-logged forests (Mann-Whitney: Z=4.339, N=205, p<0.005). These results indicated that richness and diversity of bird species assemblages appear to decline following recent inundation phase. Nevertheless, the forests in the dam area still harbour charismatic species such as eagles (Family: Accipitridae) and hornbills (Family: Bucerotidae) which suggests that this habitat is relatively important for birds.
Past experiences with surprise medical bills drive issue knowledge, concern and attitudes toward federal policy intervention

Abstract Scholars and journalists have devoted considerable attention to understanding the circumstances in which Americans receive surprise medical bills. Previous research on this issue has focused on the scope of the problem, including the conditions that are most likely to lead to surprise bills. However, the existing literature has almost exclusively relied on claims data, limiting our understanding of consumer experiences and attitudes toward policy changes to address surprise billing. Using a survey administered to a nationally representative sample of 4998 Americans, we analyze consumer experiences with surprise billing, knowledge of the issue, how concerned Americans are about receiving surprise bills and how past experiences influence policy preferences toward federal action on surprise billing. Our analysis demonstrates that knowledge and concern about surprise billing are the highest among the educated and those who have previously received a surprise bill. These factors also predict support for federal policy action, with high levels of support for federal policy action across the population, including among both liberals and conservatives. However, more detailed federal policy proposals receive significantly less support among Americans, suggesting that stand-alone policy action may not be viable. Our results show bipartisan support among American consumers for federal action on surprise billing in the abstract but no consistent views on specific policy proposals.
Three-year clinical outcomes and posterior corneal elevation change after small-incision lenticule extraction in suspicious corneas

This long-term study found that the safety and efficacy outcomes and posterior corneal elevation changes after SMILE is similar in eyes with suspicious tomographic features to that in normal eyes. Purpose: To determine the long-term clinical outcomes and change in posterior corneal elevation after small-incision lenticule extraction (SMILE) in eyes with suspicious tomographic features. Setting: Hospital clinic. Design: Retrospective, case-controlled, observational. Methods: This study included 43 patients with suspicious corneas (group A), defined by corneal morphology and a final D score from a Scheimpflug camera (Pentacam), and 43 patients with normal corneal topography (group B). Refraction, visual acuity, and posterior corneal elevation over a 6-mm central diameter, including posterior central elevation (PCE), posterior elevation at the thinnest point (PTE), and posterior maximal elevation (PME), were measured preoperatively and at 6 months, 12 months, and 36 months postoperatively. Results: The preoperative spherical equivalent was −5.51 ± 1.33 D in group A (n = 43) and −5.41 ± 1.19 D in group B (n = 43). Postoperative uncorrected distance visual acuity was 20/20 or better in 39 (91%) of 43 eyes in group A and 41 (95%) of 43 eyes in group B (P = .160); all eyes in both groups remained stable or had gained corrected distance visual acuity. The mean change in PCE, PTE, and PME at 3 years was −1.22 ± 2.65 μm, −1.21 ± 2.70 μm, and −1.00 ± 5.09 μmin group A and −1.76 ± 3.25 μm, −1.60 ± 3.33 μm, and −1.56 ± 5.01 μm in group B, respectively, indicating a tendency for backward displacement of the posterior surface, whereas the between-group difference was not statistically significant (P = .154, P = .547, and P = .319, respectively). Conclusions: Refraction, visual outcomes, and posterior corneal shift seem comparable between corneas with normal and suspicious tomographic features three years after SMILE. More long-term studies are warranted to corroborate the findings of this study.
Prevalence and Factors Associated with Food Insecurity among Older Adults in Sub-Saharan Africa: A Systematic Review

Abstract Food insecurity has been undermining the health and well-being of a growing number of older adults in Sub-Saharan Africa. This review aimed to examine the prevalence of food insecurity and the related contributing factors of food insecurity among older adults in Sub-Saharan Africa. We used PubMed, Scopus, ScienceDirect, and Web of Science Core Collection as our search engines and included 22 articles for data extraction. Prevalence of severe and moderate food insecurity in households with older adults ranged from 6.0 to 87.3% and from 8.3 to 48.5%, respectively. Various socio-economic (e.g., low education level, being widowed, low income, lower wealth position of households, living in a rental house, living in rural areas, lack of social grants or pensions), demographic (e.g., female, Black racial group, larger family size), and health and nutrition status-related (e.g., self-reported poor health status, having a functional and mobility-related disability, psychological disorders) factors influence food insecurity in older adults in Sub-Saharan Africa. The findings of this review can help stakeholders to prioritize the issue of food insecurity, design and implement policies and programs to improve food security among older adults in Sub-Saharan Africa.
Matching-adjusted indirect comparison of pneumococcal vaccines V114 and PCV20

ABSTRACT Background V114 (15-valent pneumococcal conjugate vaccine [PCV15]) and a 20-valent PCV (PCV20) are approved for adults (≥18 years) in the United States. We present methodologies to indirectly compare immune responses to V114 versus PCV20. Research design and methods Indirect treatment comparison and matching-adjusted indirect comparison (MAIC) were performed to estimate opsonophagocytic activity (OPA) geometric mean titer (GMT) ratios of V114/PCV20 at 30 days post-vaccination with PCV13 as common comparator for 13 serotypes (STs) shared with a 13-valent PCV (PCV13) among pneumococcal vaccine-naïve adults aged ≥60 years. Data from three V114 studies were pooled (V114, N = 2,196; PCV13, N = 843). In the MAIC analysis, data were reweighted, matching participant age and sex in NCT03760146 (PCV20, N = 1,507; PCV13, N = 1,490). Results The lower bound of V114/PCV20 OPA GMT ratio for all PCV13 STs is greater than the prespecified 0.5 non-inferiority margin and those for five PCV13 STs (3, 6A, 6B, 18C, and 23F) are greater than the prespecified 1.2 superiority margin. V114 was associated with 77% greater OPA GMT for ST3 versus PCV20. Conclusion V114 was non-inferior to PCV20 for all PCV13 STs and statistically superior for five PCV13 STs.
Anatomy into Interior Lamellar Assembly in Nuclei-Dependent Diversified Morphologies of Poly(l-lactic acid)

Sophisticated dissection into the interiors of the three different birefringent types of poly(l-lactic acid) (PLLA) spherulites via delicate fracturing across the thickness sections, coupled with proper etching techniques, was adopted to reveal the correlations between the diversified birefringence patterns and interior lamellae assembly. The three types of spherulites are circularly ringed spherulite (type 1), hexagon-shaped axialite (type 2), and circularly core–stripe dendrites (type 3). Such morphological diversification originates from different nuclei geometries. For all three different types (circularly ringed, hexagonal, and core–stripe) of PLLA aggregation into spherulites or dendrites/axialites, the dissected inner lamellar arrangement shares universal commonality of intersecting at a 60° angle in the intersection between different lamellar species, with distinct discontinuity in the grating structures being characteristic of all three types of aggregated PLLA spherulites. This kind of grating a.
Quantum theory of atoms in molecules in condensed charge density space

By leveraging the fundamental doctrine of the quantum theory of atoms in molecules — the partitioning of the electron charge density (ρ) into regions bounded by surfaces of zero flux — we map the gradient field of ρ onto a two-dimensional space called the gradient bundle condensed charge density ([Formula: see text]). The topology of [Formula: see text] appears to correlate with regions of chemical significance in ρ. The bond wedge is defined as the image in ρ of the basin of attraction in [Formula: see text], analogous to the Bader atom, which is the basin of attraction in ρ. A bond bundle is defined as the union of bond wedges that share interatomic surfaces. We show that maxima in [Formula: see text] typically map to bond paths in ρ, though this is not necessarily always true. This observation addresses many of the concerns regarding the chemical significance of bond critical points and bond paths in the quantum theory of atoms in molecules.
Autoignition Control of Fuel and Air Mixtures Using Photochemical Isomerization

Autoignition control of fuel and air mixtures via photochemical isomerization was simulated using chemical kinetic calculations for the ignition of 1,3-cyclohexadiene diluted in n-pentane. The calculations showed that ignition in a homogeneous charge compression ignition engine may be controlled if the fuel is photochemically isomerized using light irradiation prior to the combustion process. The calculations illustrate how photochemical reactions may be applied to fuels, to control the combustion process in engines. The theoretical energy required to achieve the photochemical conversion, based on the quantum conversion, constitutes 0.3% of the fuel energy, which may be offset by increased engine efficiency resulting from ignition timing control.
Tax Complexity and Inward Investment Martina Lawless

The negative relationship between host-country tax rates and FDI has been tested in a large number of papers. This paper looks at a different channel through which tax systems could affect FDI, namely the complexity of the tax system. Complying with tax authority requirements can be extremely time consuming for business and this implies an additional cost for more complex tax systems. We use measures of the time taken to deal with tax obligations and the number of tax payments for a representative firm compiled by the World Bank to examine their effect on FDI selection and flows from 16 OECD FDI-source countries to 57 host countries. We find a negative and significant effect of tax rates in line with other studies. In addition, the tax complexity measures are found to have a significant inhibiting effect on the presence of FDI for a country pair, but have little impact on the level of the FDI flow once it is established. In other words, the complexity measures affect FDI primarily through the extensive margin. A 10% reduction in tax complexity is found to be comparable in its effect on FDI to a one percentage point reduction in the effective corporate tax rate. The results are robust to the inclusion of other proxies for bureaucracy in the host country.
Outsourcing Services: A Theory of Special District Incorporation

Abstract In this study, we assume special district incorporation is the outsourced service from general-purpose governments. Once a special district is created, general-purpose governments have little incentives to provide overlapping services together with special districts in a designated area. Since any failure of management is not shared between politically and financially independent entities, the general-purpose governments externalize some service functions with some contribution to government performance. We test how the costs associated with service production of general-purpose governments affect the incorporation of specific types of special districts. Using negative binomial estimations, we find that services that require the high level of initial investment and have performance qualities that are difficult to evaluate are selectively outsourced.
The role of (social) media in political polarization: a systematic review

ABSTRACT Rising political polarization is, in part, attributed to the fragmentation of news media and the spread of misinformation on social media. Previous reviews have yet to assess the full breadth of research on media and polarization. We systematically examine 94 articles (121 studies) that assess the role of (social) media in shaping political polarization. Using quantitative and qualitative approaches, we find an increase in research over the past 10 years and consistently find that pro-attitudinal media exacerbates polarization. We find a hyperfocus on analyses of Twitter and American samples and a lack of research exploring ways (social) media can depolarize. Additionally, we find ideological and affective polarization are not clearly defined, nor consistently measured. Recommendations for future research are provided.
Exploring influencers of strategic change processes: evidence from five government businesses in the Omani context

Abstract This article presents an exploratory multiple case study conducted on five different government businesses in Oman with the aim of developing a comprehensive framework of strategic change influencers and showing their impact on change implementation and change outcomes. Data was collected via in-depth semi-structured face-to-face interviews with forty-two managers from the top, middle and lower levels and staff from different divisions. The study utilizes the process approach and the contingency perspective to highlight the main influencers of multiple strategic change processes. The data was analyzed via thematic analysis. The findings revealed four main influencers across the five cases one of which was found to moderate the effects of the remaining influencers. This study contributes to the fields of organizational change, strategy, leadership and HRM. It offers new and compelling context-specific insights based on a deep understanding of practice. Implications for theory and practice are discussed.
Common Murre (Uria aalge) die-off in the Kodiak Archipelago, Alaska, April 2015–April 2016

ABSTRACT A mass die-off of Common Murres (Uria aalge) occurred from spring 2015 to spring 2016 in the northern Gulf of Alaska. Seabird die-offs have been recorded previously in the region, but this event was unique in its long duration and wide spatial extent. In response to the die-off, Kodiak National Wildlife Refuge (NWR) biologists conducted systematic beach surveys along the road system adjacent to the city of Kodiak and compiled reports from local citizens in remote locations throughout the Kodiak Archipelago to document the number of dead birds observed on beaches. Analysis of beached bird records indicated that at least 1,994 dead Common Murres were observed in the Kodiak Archipelago from 4 April 2015 to 26 April 2016. Extrapolating the density estimate, based on carcasses counted on systematic surveys on the Kodiak road system (55 murres/km, SE = 12), to all beaches in the Kodiak road system study region in the same biophysical habitat class based on Alaska ShoreZone coastal mapping, yielded an estimate of 6,305 dead Common Murres (95% CI = 3,522–9,088). In addition to Common Murres, carcasses of another 65 birds representing 15 species were found on beaches on the Kodiak road system during the die-off. The die-off event was preceded by a large-scale inshore movement by marine bird species typically seen offshore (Common Murres and shearwater species), as documented by Kodiak NWR survey data and by local observers throughout the archipelago. Survey data indicate the population estimate for Common Murres in the northeastern region of the archipelago increased from 711 in June 2012 to 31,543 in June 2015 (4,335% increase), and from 5,063 in August 2012 to 64,039 in August 2015 (1,165% increase).
Spatial and temporal overlap between foraging shorebirds and spawning horseshoe crabs (Limulus polyphemus) in the Cape Romain-Santee Delta Region of the U.S. Atlantic coast

ABSTRACT Shorebird use of horseshoe crab (Limulus polyphemus) eggs as food items has been well documented along the Atlantic coast of the United States at northeastern stopover sites such as the Delaware Bay. However, the relationship between migratory shorebirds and horseshoe crab eggs has not been well studied in the South Atlantic Bight. The objective of our study was to assess the spatial and temporal overlap between the density of horseshoe crab eggs and the relative abundance of foraging shorebirds during spring migration in the Cape Romain-Santee Delta Region (CRSD), South Carolina, USA. The CRSD is a site of international importance for shorebirds that supports ∼100,000 shorebirds annually. We also sought to determine if horseshoe crab eggs were present in the diets of shorebirds at these sites. We monitored study plots between March and June 2015–2016 at predicted horseshoe crab spawning sites on beaches throughout Cape Romain National Wildlife Refuge. We conducted weekly shorebird surveys and collected core samples of beach substrate twice per month to measure densities of horseshoe crab eggs. We found a positive correlation between number of foraging shorebirds and horseshoe crab eggs for both years. In a molecular analysis of shorebird fecal samples, 95% of the samples tested contained DNA from horseshoe crab eggs. The spatial and temporal overlap between shorebirds and horseshoe crab eggs, and the dietary analysis of fecal samples, suggest that there are areas of localized horseshoe crab spawning that shorebirds can utilize as a food source during spring in Cape Romain National Wildlife Refuge.
Discrimination against mobile European Union citizens before and during the first COVID-19 lockdown: Evidence from a conjoint experiment in Germany

One of the greatest achievements of the EU is the freedom of movement between member states offering citizens equal rights in EU member states. EU enlargement and the COVID-19 pandemic allow for a critical test of whether EU citizens are indeed treated equally in practice. We test preferential treatment of EU citizens in two hypothetical choice experiments in Germany at two different time points: in the period before and during the COVID-19 pandemic lockdown. Theories of responses to threat suggest that the COVID-19 crisis should increase discrimination against mobile EU citizens. While our findings reveal sizeable discrimination based on nationality and language proficiency of mobile EU citizens, the findings also suggest that, contrary to expectations, discrimination did not increase in the initial COVID-19 crisis period.
Curating Quality? How Twitter’s Timeline Algorithm Treats Different Types of News

This article explores how Twitter’s algorithmic timeline influences exposure to different types of external media. We use an agent-based testing method to compare chronological timelines and algorithmic timelines for a group of Twitter agents that emulated real-world archetypal users. We first find that algorithmic timelines exposed agents to external links at roughly half the rate of chronological timelines. Despite the reduced exposure, the proportional makeup of external links remained fairly stable in terms of source categories (major news brands, local news, new media, etc.). Notably, however, algorithmic timelines slightly increased the proportion of “junk news” websites in the external link exposures. While our descriptive evidence does not fully exonerate Twitter’s algorithm, it does characterize the algorithm as playing a fairly minor, supporting role in shifting media exposure for end users, especially considering upstream factors that create the algorithm’s input—factors such as human behavior, platform incentives, and content moderation. We conclude by contextualizing the algorithm within a complex system consisting of many factors that deserve future research attention.
Demystifying the COVID-19 Infodemic: Conspiracies, Context, and the Agency of Users

This article presents new empirical insights into what people do with conspiracy theories during crises. By suppressing the impulse to distinguish between truth and falsehood, which has characterized most scholarship on the COVID-19 “infodemic,” and engaging with claims surrounding two popular COVID-19 conspiracies—on 5G and on Bill Gates—in South Africa and Nigeria, we illustrate how conspiracies morph as they interact with different socio-political contexts. Drawing on a mixed-method analysis of more than 6 million tweets, we examine how, in each country, conspiracies have uniquely intersected with longer-term discourses and political projects. In Nigeria, the two conspiracies were both seized as opportunities to extend criticism to the ruling party. In South Africa, they produced distinctive responses: while the 5G conspiracy had limited buy-in, the Gates conspiracy resonated with deep-rooted resentment toward the West, corporate interests, and what is seen as a paternalistic attitude of some external actors toward Africa. These findings stress the importance of taking conspiracy theories seriously, rather than dismissing them simply as negative externalities of digital ecosystems. Situating conspiracies in specific dynamics of trust and mistrust can make an important difference when designing responses that are not limited to broadcasting truthful information, but can also enable interventions that account for deeply rooted sentiments of suspicion toward specific issues and actors, which can vary significantly across communities.
Implications of Facebook Engagement Types and Feed’s Social Content for Self-Esteem via Social Comparison Processes

Self-esteem, generally understood as subjective appraisal of one’s social worth and qualities, is related to how people use social media and the gratifications derived from their use—processes driven in part by social comparison. Two major components of the social media experience drive social comparison processes: (1) what content people engage with (feeds content) and (2) how they engage with such content (engagement type). We conducted an eye-tracking study (N = 38), to measure viewing time spent on individual Facebook posts and paired this measurement with clicking behaviors. We found that spending more time looking at posts and clicking on more of them was associated with lower self-esteem for people with more social content on their feeds. We discuss the importance of examining browsing behaviors as a combination of viewing time, clicking, and feed’s content—especially given its potential impact on well-being outcomes such as self-esteem via social comparison processes.
