Background: Data on complications in children with seasonal influenza virus infection are limited. We initiated a nation-wide three-year surveillance of children who were admitted to a paediatric intensive care unit (PICU) with severe seasonal influenza. Methods: From October 2005 to July 2008, active surveillance was performed using an established reporting system for rare diseases (ESPED) including all paediatric hospitals in Germany. Cases to be reported were hospitalized children < 17 years of age with laboratory-confirmed influenza treated in a PICU or dying in hospital. Results: Twenty severe influenza-associated cases were reported from 14 PICUs during three pre-pandemic influenza seasons (2005-2008). The median age of the patients (12 males/8 females) was 7.5 years (range 0.1-15 years). None had received vaccination against influenza. In 14 (70%) patients, the infection had been caused by influenza A and in five (25%) by influenza B; in one child (5%) the influenza type was not reported. Patients spent a median of 19 (IQR 12-38) days in the hospital and a median of 11 days (IQR 6-18 days) in the PICU; 10 (50%) needed mechanical ventilation. Most frequent diagnoses were influenza-associated pneumonia (60%), bronchitis / bronchiolitis (30%), encephalitis / encephalopathy (25%), secondary bacterial pneumonia (25%), and ARDS (25%). Eleven (55%) children had chronic underlying medical conditions, including 8 (40%) with chronic pulmonary diseases. Two influenza A- associated deaths were reported: i) an 8-year old boy with pneumococcal encephalopathy following influenza infection died from cerebral edema, ii) a 14-year-old boy with asthma bronchiale, cardiac malformation and Addison’s disease died from cardiac and respiratory failure. For nine (45%) patients, possibly permanent sequelae were reported (3 neurological, 3 pulmonary, 3 other sequelae). Conclusions: Influenza-associated pneumonia and secondary bacterial infections are relevant complications of seasonal influenza in Germany. The incidence of severe influenza cases in PICUs was relatively low. This may be either due to the weak to moderate seasonal influenza activity during the years 2005 to 2008 or due to underdiagnosis of influenza by physicians. Fifty % of the observed severe cases might have been prevented by following the recommendations for vaccination of risk groups in Germany.
U.S. and German Approaches to Regulating Retail Development: Urban Planning Tools and Local Policies
(2012)
This dissertation examines retail development regulation in the U.S. and in Germany, comparing the various urban planning tools and policies in use by municipal governments. These similarities and differences are explored through research into three case study cities in each country, with special attention paid to how these governments regulate large-scale or "big box" retail.
This thesis on the “Impacts of extreme hydro-meteorological events on electricity generation and possible adaptation measures – a GIS-based approach for corporate risk management and enhanced climate mitigation concepts in Germany” presents an identification of hydro-meteorological extreme events in Germany and their effects on electricity generating units, i.e. on conventional thermal and nuclear power plants as well as on installations of the renewable energies of hydropower, wind energy and photovoltaic installations. In addition, adaptation measures and strategies are named that help power plant operators to prepare for a changing climate. Due to the different requirements of large facility operators and local planners and owners of renewable energies, the work contains the two approaches of corporate risk management and climate mitigation concepts. A changing climate not only consists of a shift in mean values of weather parameters such as global and regional air temperature and precipitation, but may also result in more frequent and more severe single events such as extreme precipitation, tornadoes and thunderstorms. In two case studies, these findings are implemented into an adjusted general risk management structure. This is enhanced by the use of Geographical Information Systems (GIS) to accomplish a localisation of events and infrastructure. The first example gives insight into the consequences of ice throw from wind turbines and how climate mitigation concepts can act as a framework for an adapted, sustainable energy planning. The second example on the other hand highlights a GIS-based flood risk management for thermal power plants and the benefits of an adjusted corporate risk management cycle. The described approach leads to an integrated management of extreme hydro-meteorological events at power plant site respectively district level by combining two cycles of site-related and local planning in addition to GIS-based analyses. This is demonstrated as an example by the comparison of two districts in Germany. The practical outcome is a comprehensive support for decision-making processes.
Chapter I
The gradual turnover of dead organic material into mineral nutrients is a key ecological function, linking decomposition and primary production, the essential parts of the nutrient-energy cycle. However, disturbances in terms of species or resource losses might impair the equilibrium between production and decomposition. Humanity has converted large proportions of natural landscapes and intensified land-use activity for food production. Globally, only very few areas are totally unaffected by human activity today.
To ensure the maintenance of both essential ecosystem services, knowledge about the interplay of biodiversity and ecosystem functioning as well as effects of intensified management on both is crucial. The vast majority of terrestrial biomass production as well as decomposition take place in forest ecosystems. Though forestry has a long sustainable history in Europe, its intensification during the last century has caused severe impacts on forest features and, consequently, on the associated biota, especially deadwood dependent organisms. Among these, saproxylic beetles are the most diverse group in terms of species numbers and functional diversity, but also most endangered due to habitat loss. These features classify them as ideal research organisms to study effects of intensified forestry on ecosystem services. The BELONGDEAD project located in Germany aimed to investigate deadwood decay and functional consequences of diversity changes in the associated fauna on the decomposition process from the initialisation of deadwood decay to complete degradation.
As part of the BeLongDead project, this dissertation focussed on saproxylic beetle species, thereby evaluating (1) regionally effects of tree species identity of fresh deadwood and (2) forest management of varying intensities on the diversity, abundance and community composition of saproxylic beetles (chapter II); (3) the specialisation degree of different trophic guilds of saproxylic beetles, and thus the stability and robustness of their interaction networks against disturbances (chapter III); (4) the impact of environmental features of local to regional spatial scales on species richness of saproxylic beetles differing in their habitat niche in terms of deadwood decay stages (chapter IV).
Chapter II
The vast majority of European forest ecosystems have been anthropogenically affected, leaving less than 1% of the about 1 milliard hectare as natural forests. A long history of forestry and especially the technological progress during the last century have caused massive habitat fragmentation as well as substantial loss of essential resources in European forest ecosystems. Due to this, the substrate-dependent group of saproxylic beetles has experienced severe species losses. Thus, investigations concerning saproxylic diversity and deadwood volume were badly needed. However, the importance of different deadwood in terms of tree species identity for the colonization by saproxylic beetles under different local and regional management regimes is poorly understood. Therefore, we studied possible regional differences in colonization patterns of saproxylic beetle species in a total of 688 fresh deadwood logs of 13 tree species in 9 sites of managed conifer and beech forests, and unmanaged beech forests, respectively. We found that tree species identity was an important driver in determining saproxylic species composition and abundance within fresh deadwood. However, saproxylic species showed different colonization patterns of deadwood items of the same tree species among the study regions. Regionally consistent, conifer forests were most diverse. We attribute the latter result to the historically adaption of saproxylic beetle species to semi-open forests, which conditions are actually best reflected by conifer forests. To preserve a diverse local species pool of early successional saproxylic beetles, we suggest an equal high degree of deadwood diversity in a tree species context in due consideration of regional differences.
Chapter III
The extinction risk of a particular species corresponds with its species-specific requirements on resources and habitat conditions, in other words with the width of the species` ecological niche. Species with a narrow ecological niche are defined as specialists. Members of this group experience higher extinction risk by resource limitation than generalists, which are able to utilize a variety of resources. For the classification of species as specialists or generalists, thus evaluating possible extinction risks, ecologists use the concept of interaction networks. This method has often been applied for mutualistic or antagonistic plant-animal interactions, but information for networks of detritivores is scarce. Therefore, saproxylic beetle species sampled as described in chapter II were categorised according to their larval diet; additionally their interaction networks (N=108) with 13 dead host tree species were analysed. Specialisation degree was highest for wood-digesting beetles and decreased with increasing trophic level. Also the network indices evaluating robustness and generality indicated a higher susceptibility to species extinctions for xylophagous than for mycetophagous and predatory beetles. The specialisation of xylophagous species on specific tree species might be an adaption to tree species specific ingredients stored for defence against pathogens and pests. However, we conclude that the high specialisation degree of xylophages and thus their higher extinction risk by resource loss harbours certain dangers for ecosystem function and stability as species diversity is positively linked to both.
Chapter IV
Populations depend on individual emigration and immigration events to ensure genetic exchange. For successful migration it is of utmost importance that spatially separated populations are obtainable by specimen. Migratory success depends on the one hand on the species dispersal abilities and on the other on the availability of suitable habitats in the surrounding landscape in which the distinct host populations exist. However, consequences of intensive forest management correspond not only to severe reduction of local deadwood amount, but, among others, also a change in tree species composition and high levels of fragmentation in the surrounding forest area. Saproxylic beetle species differ in their dispersal behaviour according to the temporal availability of their preferred habitat. Generally, early successional saproxylic beetles are able to disperse over large distances, whereas beetles inhabiting advanced decayed wood often remain close to their larval habitat. Due to this, environmental factors might affect saproxylic beetle guilds differently. We classified the saproxylic beetles sampled as described in chapter II according to their calculated habitat niche as early, intermediate or late successional saproxylic beetles. For the different guilds the effects of 14 environmental factors on different spatial scales (stand factors at 0.1 km radius, landscape composition at 2 km radius, and regionally differing abiotic factors in 400 km to 700 km distance) were investigated. Consistently for all guilds, species richness decreased with fragmentation at local and landscape scale, and increased in warmer climate. However, we found contradictory results between the guilds to some extent. We relate this to guild specific habitat requirements of the saproxylic beetles. Therefore, for the development of appropriate conservation practices guild-specific requirements saproxylic beetles have to be considered not only locally but on larger spatial scales.
Chapter V
In conclusion, this dissertation identified main drivers of early successional saproxylic beetle species richness on various spatial scales. Our results emphasize the importance to develop management schemes meeting species-specific and guild-specific habitat requirements of the saproxylic beetle fauna at relevant spatial and temporal scales. Therefore, short-term actions suggested for sustainable forest management should be the focus on a diverse tree species composition consisting of indigenous tree species with respect to regional differences. Moreover, senescent trees, fallen and standing deadwood should remain in the forests, and some tree individuals should be allowed to grow old. Long-term actions should involve the reduction of forest fragmentation and the connection of spatial widely separated forest fragments. Furthermore, to fully understand the effects of forest management long-term research should be conducted to compare habitat requirements of intermediate and late successional beetles with the results presented in this dissertation.
The dissertation at hand focuses on the enforcement of accounting standards in Germany. The legal basis of the external enforcement of accounting standards in Germany was created by the „Bilanzkontrollgesetz” (Financial Reporting Enforcement Act) at the end of 2004. An enforcement mechanism was installed to enforce accounting standard compliance by regular reviews of disclosed financial statements. The system was established as implementation of EU guidelines. Since 2005, International Financial Reporting Standards (IFRS) shall be applied for consolidated financial statement of firms listed on a regulated market segment within the European Union (EU) (Regulation EC No. 1606/2002). Simultaneously to the harmonization of accounting standards, the EU fostered the standardization of enforcement systems to ensure compliance with international accounting standards. Par. 16 of the so-called “IAS Regulation” mandates the “Committee of European Securities Regulators” (CESR) to “develop a common approach to enforcement". Germany’s unique two-tiered system operates since July 2005; it involves the “Deutsche Pruefstelle fuer Rechnungslegung” (Financial Reporting Enforcement Panel), a newly established private organization primarily assigned to conduct the reviews. As the second tier, the „Bundesanstalt fuer Finanzdienstleistungsaufsicht” (Federal Financial Supervisory Authority) has the sovereign authority to order the publication of errors („error announcements“) and if necessary, to force the cooperation of firms in the review process.
The dissertation is structured as follows. A general introduction focuses on the theoretical background and the reasoning for the need of external enforcement mechanisms. The common approach to enforcement in the European Union is described. Building on this, the thesis consists of three individual essays that analyze three specific questions in the context of the enforcement of financial reporting standards in Germany.
The first paper focuses on the systematical evaluation of the information contained in 100 selected error announcements (from a total population of 151 evaluable announcements). The study finds that error announcements on average contain 3.64 single errors and 77% affect the reported profit. Relatively small as well as big, highly levered and rather unprofitable firms are overrepresented in the sample of misstatement firms. In a second step, the essay investigates the development of censured firms over time; the pre- and post-misstatement development of the firms in terms of balance sheet data, financial ratios and (real) earnings management are tracked. The analysis detects increasing leverage ratios and a decline in profitability over time. In the year of misstatement firms report large total and discretionary accruals, indicating earnings management. Compared to matched control firms, significant differences in profitability, market valuation, earnings management and real activities manipulations are observable. A major contribution of this first study is the examination of trends in financial data and (real) earnings management over a number of years surrounding misstatements as well as the elaboration of the distinction to non-misstating firms. The results show the meaning of the enforcement of IFRS for the quality of financial reporting to standard setters, policy makers, and investors in Germany.
The second paper examines the interrelation of enforcement releases, firm characteristics and earnings quality. Prior literature documents the correlation between underperformance in financial ratios and the probability of erroneous disclosure of financial statements; this study provides evidence for differences in characteristics between firms with enforcement releases and control firms as well as a broad sample of German publicly traded firms (4,730 firm-year observations). Furthermore, research affirms the connection of financial ratios to earnings quality metrics. The accuracy of financial information is considered to be correlated with its quality and therefore the differences in earnings quality between various sub-samples is examined. Overall, the results document the underperformance in important financial ratios as well as indicate an inferior earnings quality of firms subject to enforcement releases vis-a-vis the control groups. These results hold with regard to both different earnings quality specifications and different periods observed. This study appends the earnings quality discussion and contributes to develop a comprehensive picture of accounting quality for the unique institutional settings of Germany. The paper shows that a conjoint two-tier public and private enforcement system is effective and might be an adequate model for other countries. Implications for the regulation of corporate governance, the enforcement panel and the auditor are identified.
The third essay additionally considers the role of the auditor. The firms subject to error announcements are used to evaluate the consequences of increasing earnings management over time on enforcement releases and their recognition in audit fees. Prior literature provides evidence on a phenomenon called „balance sheet bloat” that is due to income increasing earnings management and later influences the disclosure of misstated financial statements. The evidence of earnings management recognition in audit fees and findings on the content of future information in audit fees leads to the hypothesis that auditors recognize increasing audit risk in fees before the enforcement process starts. The study extends related earnings management and audit fee literature by modeling the development of earnings management within the misstatement firms and systematically link it to auditor reactions. Significant predictive power of different commonly used accrual measures for enforcement releases in the period prior and up to the misstatement period are found by the study. In the same period of time an increase in audit fees, e.g. the recognition of increased audit risk, can be observed. A possible audit fee effect after the misstatement period is investigated, but no significant relation is obtained.
The dissertation closes with a summary of the main findings, a conclusion to the connection of the three essays as well as subsumption of findings in the accounting literature.
Chapter 2 concerns the audit market for German credit institutions (excluding savings banks and cooperative banks), and the presented study allows conclusions to be drawn regarding recent concentration levels of this particular audit market. The last reliable (statistical) studies concerning the audit market for German credit institutions were published several years ago (Grothe 2005; Lenz 1996b; Lenz 1997; Lenz 1998). This is surprising because parts of the new regulations concerning the audit market for public-interest entities—which should also apply to credit institutions (European Commission 2006c)—in Europe would require analyses of the audit market concentration to be performed on a regular basis. Therefore, this study begins to fill this research gap, and it reveals that the audit market for German credit institutions was highly concentrated (market leadership: KPMG AG WPG and PricewaterhouseCoopers AG WPG) in 2006 and 2010. Moreover, the findings also highlight that between these years, neither a notable trend toward higher levels of concentration nor a deconcentration process was evident. Finally, it is illustrated that the regulatory requirements for publishing audit fees and the corresponding right to claim exemption (§§ 285 Sentence 1 No. 17, 314 (1) No. 9 Commercial Code) do not allow the calculation of concentration figures that cover the entire audit market for credit institutions. Thus, it will continue to be necessary to use surrogates for audit fees, and analyses reveal that the arithmetic mean of the total business volume (or total assets) of a credit institution and its square root is a very good surrogate for calculating concentration measures based on audit fees.
Chapter 3 seeks to determine whether public oversight of public-interest entities (PIEs) increases audit fees specifically in the financial industry, which is already a highly regulated industry characterized by intense supervision. To answer this question, a sample of 573 German credit institutions is examined over the 2009–2011 period, as not all credit institutions were considered PIEs in Germany (until very recently). First, the results show that a credit institution’s business risk is related to audit fees. In addition, the findings reveal not only that PIE credit institutions pay statistically significantly higher audit fees but also that this effect is economically substantial (representing an audit fee increase of 31.38%). Finally, there are several indications that the relationship between (other) credit institutions’ business risks and audit fees is greater for PIE credit institutions.
Chapter 4 examines the association between the results of auditor ratification votes and perceived external financial reporting quality. As has been recently remarked by Wei et al. (2015), far too little is known about shareholders’ interests in and perceptions of the election, approval or ratification of auditors. Although auditor ratification by shareholders is normally a routine, non-binding action and the voting ratios are in the range of 95% or higher, the SEC emphasized the importance of this process by amending the disclosure requirements for such voting results in 2010 (SEC 2009; SEC 2010). This study demonstrates that the results of auditor ratification votes are associated with market reactions to earnings surprises (SEC registrants; 2010 to 2013). Moreover, there are moderate indications that this effect may be positively related to higher levels of information asymmetry between managers and shareholders, that such voting results contain incremental informational content beyond that of other publicly available audit-related information, and that the time lag between the ratification of an auditor and the earnings announcement influences the vote’s importance. Finally, the study sheds additional light on an overlooked audit-related topic (e.g., Dao et al. 2012; Hermanson et al. 2009; Krishnan and Ye 2005; Sainty et al. 2002), and illustrates its relation to accounting. More importantly, the provided evidence indicates that disclosure of the results of auditor ratification votes might benefit (prospective) shareholders.
Chapter 5 addresses the question of whether and when shareholders may have a negative perception of an auditor’s economic dependence on the client. The results for a Big 4 client sample in the U.S. (2010 to 2014) show that the economic importance of the client—measured at the audit office-level—is negatively associated with shareholders’ perceptions of external financial reporting quality—measured in terms of the earnings response coefficient and the ex ante cost of equity capital—and, therefore, is perceived as a threat to auditor independence. Moreover, the study reveals that shareholders primarily regard independence due to client dependence as a problem for firms that are more likely to be in financially distressed conditions.
Economists (should) care about regions! On the one hand this is true because macroeconomic shocks have vastly different effects across regions. The pressing topics of robotization
and artificial intelligence, Brexit, or U.S. tariffs will affect Würzburg differently than Berlin,
implying varying interests among its population, firms and politicians. On the other hand,
shocks in individual regions, such as inventions, bankruptcies or the attraction of a major
plant can, through trade and input-output linkages, magnify to aggregate effects of macroe-
conomic importance. Yet, regional heterogeneities in Germany and the complicated network
of linkages that connect regions are still not well documented nor understood. A fact that
is especially true for local labor markets that are of core interest to regional policy makers
and that also feature substantial heterogeneity.
This thesis provides a thorough quantification of such heterogeneities and an in-depth analysis of the sources and mechanisms that drive these differences.
This dissertation consists of three contributions. Each addresses one specific aspect of intergenerational income mobility and is intended to be a stand-alone analysis. All chapters use comparable data for Germany and the United States to conduct country comparisons. As there are usually a large number of studies available for the United States, this approach is useful for comparing the empirical results to the existing literature.
The first part conducts a direct country comparison of the structure and extent of intergenerational income mobility in Germany and the United States. In line with existing results, the estimated intergenerational income mobility of 0.49 in the United States is significantly higher than that of 0.31 in Germany. While the results for the intergenerational rank mobility are relatively similar, the level of intergenerational income share mobility is higher in the United States than in Germany. There are no significant indications of a nonlinear run of intergenerational income elasticity. A final decomposition of intergenerational income inequality shows both greater income mobility and stronger progressive income growth for Germany compared to the United States. Overall, no clear ranking of the two countries can be identified. To conclude, several economic policy recommendations to increase intergenerational income mobility in Germany are discussed.
The second part examines the transmission channels of intergenerational income persistence in Germany and the United States. In principle, there are two ways in which well-off families may influence the adult incomes of their children: first through direct investments in their children's human capital (investment effect ), and second through the indirect transmission of human capital from parents to children (endowment effect ). In order to disentangle these two effects, a descriptive as well as a structural decomposition method are utilized. The results suggest that the investment effect and the endowment effect each account for approximately half of the estimated intergenerational income elasticity in Germany, while the investment effect is substantially more influential in the United States with a share of around 70 percent. With regard to economic policy, these results imply that equality of opportunity for children born to poor parents cannot be reached by the supply of financial means alone. Conversely, an efficient policy must additionally substitute for the missing direct transmission of human capital within socio-economically weak families.
The third part explicitly focuses on the intergenerational income mobility among daughters. The restriction to men is commonly made in the empirical literature due to women‘s lower labor market participation. While most men work full-time, the majority of (married) women still work only part-time or not at all. Especially with the occurrence of assortative mating, daughters from well-off families are likely to marry rich men and might decide to reduce their labor supply as a result. Thus, the individual labor income of a daughter might not be a good indicator for her actual economic status. The baseline regression analysis shows a higher intergenerational income elasticity in Germany and a lower intergenerational income elasticity in the United States for women as compared to men. However, a separation by marital status reveals that in both countries unmarried women exhibit a higher intergenerational income elasticity than unmarried men, while married women feature a lower intergenerational income elasticity than married men. The reason for the lower mobility of unmarried women turns out to be a stronger human capital transmission from fathers to daughters than to sons. The higher mobility of married women is driven by a weaker human capital transmission and a higher labor supply elasticity with respect to spousal income for women as compared to men. In order to further study the effects of assortative mating, the subsample of married children is analyzed by different types of income. It shows that the estimated intergenerational income elasticity of children's household incomes is even higher than that of their individual incomes. This can be seen as an indication for strong assortative mating. If household income is interpreted as a measure of children‘s actual economic welfare, there are barely any differences between sons and daughters. The intergenerational income elasticity of spousal income with respect to parental income is again relatively high, which in turn supports the hypothesis of strong assortative mating. The elasticity of the sons-in-law with respect to their fathers-in-law in Germany is even higher than that of the sons with respect to their own fathers.
Maladaptive coping mechanisms influence health-related quality of life (HRQoL) of individuals facing acute and chronic stress. Trait emotional intelligence (EI) may provide a protective shield against the debilitating effects of maladaptive coping thus contributing to maintained HRQoL. Low trait EI, on the other hand, may predispose individuals to apply maladaptive coping, consequently resulting in lower HRQoL. The current research is comprised of two studies. Study 1 was designed to investigate the protective effects of trait EI and its utility for efficient coping in dealing with the stress caused by chronic heart failure (CHF) in a cross-cultural setting (Pakistan vs Germany). N = 200 CHF patients were recruited at cardiology institutes of Multan, Pakistan and Würzburg as well as Brandenburg, Germany. Path analysis confirmed the expected relation between low trait EI and low HRQoL and revealed that this association was mediated by maladaptive metacognitions and negative coping strategies in Pakistani but not German CHF patients. Interestingly, also the specific coping strategies were culture-specific. The Pakistani sample considered religious coping to be highly important, whereas the German sample was focused on adopting a healthy lifestyle such as doing exercise. These findings are in line with cultural characteristics suggesting that German CHF patients have an internal locus of control as compared to an external locus of control in Pakistani CHF patients. Finally, the findings from study 1 corroborate the culture-independent validity of the metacognitive model of generalized anxiety disorder.
In addition to low trait EI, high interoception accuracy (IA) may predispose individuals to interpret cardiac symptoms as threatening, thus leading to anxiety. To examine this proposition, Study 2 compared individuals with high vs low IA in dealing with a psychosocial stressor (public speaking) in an experimental lab study. In addition, a novel physiological intervention named transcutaneous vagus nerve stimulation (t-VNS) and cognitive reappraisal (CR) were applied during and after the anticipation of the speech in order to facilitate coping with stress. N= 99 healthy volunteers participated in the study. Results showed interesting descriptive results that only reached trend level. They suggested a tendency of high IA individuals to perceive the situation as more threatening as indicated by increased heart rate and reduced heart rate variability in the high-frequency spectrum as well as high subjective anxiety during anticipation of and actual performance of the speech. This suggests a potential vulnerability of high IA individuals for developing anxiety disorders, specifically social anxiety disorder, in case negative self-focused attention and negative evaluation is applied to the (more prominently perceived) increased cardiac responding during anticipation of and the actual presentation of the public speech. The study did not reveal any significant protective effects of t-VNS and CR.
In summary, the current research suggested that low trait EI and high IA predicted worse psychological adjustment to chronic and acute distress. Low trait EI facilitated maladaptive metacognitive processes resulting in the use of negative coping strategies in Study 1; however, increased IA regarding cardioceptions predicted high physiological arousal in study 2. Finally, the German vs. the Pakistani culture greatly affected the preference for specific coping strategies. These findings have implications for caregivers to provide culture-specific treatments on the one hand. On the other hand, they highlight high IA as a possible vulnerability to be targeted for the prevention of (social) anxiety.
