The Impact

This article proposes a new approach to analyze protest participation measured in surveys of uneven quality. Because single international survey projects cover only a fraction of the world’s nations in specific periods, researchers increasingly turn to ex-post harmonization of different survey data sets not a priori designed as comparable. However, very few scholars systematically examine the impact of the survey data quality on substantive results. We argue that the variation in source data, especially deviations from standards of survey documentation, data processing, and computer files—proposed by methodologists of Total Survey Error, Survey Quality Monitoring, and Fitness for Intended Use—is important for analyzing protest behavior. In particular, we apply the Survey Data Recycling framework to investigate the extent to which indicators of attending demonstrations and signing petitions in 1,184 national survey projects are associated with measures of data quality, controlling for variability in the questionnaire items. We demonstrate that the null hypothesis of no impact of measures of survey quality on indicators of protest participation must be rejected. Measures of survey documentation, data processing, and computer records, taken together, explain over 5% of the intersurvey variance in the proportions of the populations attending demonstrations or signing petitions.

The Covid-19 induced economic crisis has significantly affected almost all businesses from nearly every sector, causing severe financial problems, lack of cash assets, and decrease of revenues. In this context, the economic entities were forced to look for adjustment and rescue solutions of their activities. One possible solution for the recovery and reorganization of economic entities’ activities is demerger. This paper evaluates the impact of demerger upon the sustainable development of economic entities in terms of economic efficiency and financial performances. To achieve this goal, a statistical analysis of profitability ratios before and after the demerger, as well as a structural analysis of 268 demerger projects for the April 2012–April 2021 period, were performed. The results attest there are no significant differences between the ex-ante and ex-post financial performances. However, demerger seems to have a positive effect upon analyzed companies helping them to overcome economic hardships, rethink their business strategies, and continue their activity in the medium and long-term time horizon.

Abstract We measure the impact introducing a of 10% co-payment component on hospitalisation costs for Palestine refugees from Lebanon in public and private hospitals. This ex-post analysis provides a detailed insight on the direction and magnitude of the policy impact in terms of demand and supply for healthcare. The data was collected by the United Nations Relief and Works Agency for Palestine Refugees in the Near East and include episode level information from all public, private and Red Crescent Hospitals in Lebanon, between April 2016 and October 2017. This is a complete population episode level dataset with information from before and after the policy change. We use multinomial logit, negative binomial and linear models to estimate the policy impact on demand by type of hospital, average length of stay and treatment costs for the patient and the provider. After the new policy was implemented patients were 18% more likely to choose a (free-of-charge) PRCS hospital for secondary care, instead of a Private or Public hospital, where the co-payment was introduced. This impact was stronger for episodes with longer stays, which are also the more severe and more expensive cases. Average length of stay decreased in general for all hospitals and we could not find a statistically significant impact on costs for the provider nor the patient. We find evidence that the introduction of co-payments is hospital costs led to a shift in demand, but it is not clear to what extent the hospitals receiving this demand shift were prepared for having more patients than before, also because these are typically of less quality then the others. Regarding costs, there is no evidence that the provider managed to contain costs with the new policy, as the demand adapted to the changes. Our findings provide important information on hospitalisation expenses and the consequences of a policy change from a lessons learned perspective that should be taken into account for future policy decision making. Key messages We show that in a context of poverty, the introduction of payment for specific hospital types can be efficient for shifting demand, but has doubtable impact on costs containment for the provider. The co-payment policy can have a negative impact on patients' health since after its implementation demand increased at free-of-charge hospitals, which typically have less resources to treat patients.

The Impact

Sometimes the rivalry between shareholders and management is an indication of the level of entrenchment within the corporate environment. Managers are believed to routinely manipulate earnings in order to mislead shareholders about their company's actual economic outlook or performance. As a result, the study investigated the impact of managerial entrenchment, firm characteristics and earnings management of conglomerate companies in Nigeria. Employing the ex-post facto research design, the data was gathered from secondary source of the 6 listed conglomerate companies for the 11-year period running (2008-2018). The study used discretionary accruals a proxy for earnings management and to calculate discretionary accruals, the study used modified Jones model. The result showed that management entrenchment and firm characteristics have Impact on multinational firms ' earnings management in Nigeria. Specifically, from the conglomerate’s entrenchment proxies, CEO’s tenure has a positive and significant impact on earnings management (coff. =1.062821, p-value =0.0367) and management entrenchment as measured by CEO’s shareholding has a negative and insignificant effect on earnings management (coff. =-6252391, p-value = 0.4090) while firm size, profitability and leverage indicated a significant and positive impact on earnings management (coff, = 0.124587, p-value = 0.0000; coff. = 0.006647, p-value = 0.0431 and coff. = 0.032065, p-value = 0.0000). The study therefore recommended among others that management should reduce the debt in their capital structure in order to improve their companies’ value and their capital structure should be majorly financed by equity rather than debt and reduce CEOs tenure to minimise earnings management practices.

Abstract Catchpole, T. L., Revill, A. S., Innes, J., and Pascoe, S. 2008. Evaluating the efficacy of technical measures: a case study of selection device legislation in the UK Crangon crangon (brown shrimp) fishery. – ICES Journal of Marine Science, 65: 267–275. Bycatch reduction devices are being introduced into a wide range of fisheries, with shrimp and prawn fisheries particularly targeted owing to the heavy discarding common in these fisheries. Although studies are often undertaken to estimate the impact of a technical measure on the fishery before implementation, rarely have the impacts been assessed ex post. Here, the efficacy of the UK legislation pertaining to the use of sievenets in the North Sea Crangon crangon fishery is assessed. Three impacts were evaluated: on fisher behaviour (social), on the level of bycatch (biological), and on vessel profitability (economic). An apparent high level of compliance by skippers was identified despite a low level of enforcement. The estimated reduction in fleet productivity following the introduction of the legislation was 14%, equalling the mean loss of Crangon landings when using sievenets calculated from catch comparison trawls. Sievenets did reduce the unnecessary capture of unwanted marine organisms, but were least effective at reducing 0-group plaice, which make up the largest component of the bycatch. Clearly the legislation has had an effect in the desired direction, but it does not address sufficiently the bycatch issue in the Crangon fishery.

In this article, we introduce competition between athletes to the model of ex post doping audits by Goetsch and Salzmann. We determine the doping minimizing storing and retesting strategy for a doping agency in a competitive setting between two athletes. We demonstrate that for the doping agency, there is only one doping minimizing strategy depending on the number of athletes. Even though the athletes’ doping decision is influenced by the contest, counterintuitively, the agency’s strategy is neither influenced by the prize of the contest nor by its balance or any other contest dynamics.

Abstract Use of renewable energy sources (RES) might be one of the key factors for the triple win-win: improving energy supply security, promoting local economic development, and reducing greenhouse gas emissions. The authors ex-post evaluate the impact of two main support instruments applied in 2010-2014 – the investment support (IS) and the feed-in tariff (FIT) – on the economic viability of small scale (up to 2MWel) biogas unit. The results indicate that the electricity production cost in biogas utility roughly corresponds to the historical FIT regarding electricity production using RES. However, if in addition to the FIT the IS is provided, the analysis shows that the practice of combining both the above-mentioned instruments is not optimal because too high total support (overcompensation) is provided for a biogas utility developer. In a long-term perspective, the latter gives wrong signals for investments in new technologies and also creates unequal competition in the RES electricity market. To provide optimal biogas utilisation, it is necessary to consider several options. Both on-site production of electricity and upgrading to biomethane for use in a low pressure gas distribution network are simulated by the cost estimation model. The authors’ estimates show that upgrading for use in a gas distribution network should be particularly considered taking into account the already existing infrastructure and technologies. This option requires lower support compared to support for electricity production in small-scale biogas utilities.

In this work we study the impact of relinquishment and the adoption process in posttraumatic symptoms and stressful life events in a group of 55 adults that were adopted as children after the Spanish Civil War (1936-1939). The effects of institutionalization, maltreatment and traumatic revelation of the adopted status have also been studied. No significant differences were found between institutionalized and non-institutionalized adoptees in posttraumatic symptomatology and stressful life events frequency. However, maltreated adoptees scored significantly higher in intrusion, arousal and stressful life events frequency than non-maltreated. Similar differences were found in the comparison between adoptees with and without traumatic revelation; those adoptees who suffered traumatic revelation presented significantly higher intrusion, arousal and stressful life events frequency than those who did not suffer traumatic revelation. Traumatic revelation, alone or in association with maltreatment, seems to play an important role in posttraumatic symptoms in the sample studied.

The Impact

The serious decline in the price of crude oil in recent years has led the state government to look for new sources of revenue and becomes strict and aggressive to the assessment and collection of revenue from the existing sources. This study examines the impact of Corporate Governance Attributes on Tax planning of listed manufacturing companies in Nigeria and Malaysia. The corporate governance parameters include board size and CEO tenure while tax planning is proxied by the effective tax rate and firm size as control variable. The objective is to determine if there is a relationship between corporate governance attributes and tax planning which in turn may improve firm performance. The study adopts comparative and ex-post facto research design and will utilise panel data from annual reports and accounts of the listed companies for the period of five years (2014-2018). The Data were analysed using a panel regression technique to assess the effect of the independent variables on the dependent variable. Hausman specification test was conducted to choose between fixed and random effect estimation and the p-value is0.9863 which insignificant. The resultsfrom random effect estimation modelindicates a negative and significant relationship between CEOT, FSIZE and ETR and a positive relationship between BSIZE and ETR.Therefore, the study concludes that corporate governance mechanism plays a significant role in tax planning and Nigerian manufacturing companies pays high tax charges as compare to Malaysian food and beverages companies.

The Impact

Instruction plays a major role in the development of speaking skills for second language learners. Different approaches and methods have emerged throughout the history of language learning/teaching based on the influence of different theories of language, psychology, and related domains such as psycholinguistics, sociolinguistics, pragmatics and cultural studies. Two major trends in language teaching emerged under the influence of these mentioned language theories, namely, accuracy based versus fluency based approaches. This article gives a historical sketch up to these trends in an attempt to provide a historical background and to empirically bring evidence that wait time instruction and teaching experience can impact classroom feedback in Moroccan classes. Relevant questions related to the role of teachers’ experience in leading different types of feedback, the effect of the number of teaching years as well as the correlation between wait time instruction and the corresponding teaching experience are closely investigated. This article adheres to a mixed design or what has been identified in research methodology as ex-post facto (Cohen, Manion, Morrison, 2007). Therefore, it is both a qualitative and a descriptive one. For the type of instructions used, the results obtained show the insignificance of the impact of experience on this variable. On the other hand, results retained that wait- time instruction in comparison to other items recorded a higher significance of the impact of experience. Therefore, current article brings empirical evidence on how wait- time instruction plays a crucial role in spoken activity for second language learners.
