Oral Mucosal Trauma and Injuries

Trauma-related oral lesions are common in clinical practice of dentistry and they can impair patients’ normal oral function and cause pain in patients’ eating, chewing, and talking. An injury to the oral mucosa can result from physical, chemical, or thermal trauma. Such injuries can result from accidental tooth bite, hard food, sharp edges of the teeth, hot food, or excessive tooth brushing. Some injuries can also be caused by iatrogenic damage during dental treatment or other procedures related to oral cavity. In this chapter, oral mucosal trauma and injuries will be examined in four subclasses: physical and mechanical traumas of oral mucosa; chemical injuries of the oral mucosa; radiation injuries; and electrical, thermal burns

Dental Implants and Trauma

Implant dentistry treatment target to avoid any kind of edentulous state including tooth loss due to trauma. In the literature there are numerous case reports and few clinical studies documenting treatment options of post-trauma patients by dental implants. Principally there are some limitations of dental implant application related to the age and available bone volume of patients. Implant candidate should complete bone growth as the metallic implants do not follow bony development phases. Most often traumatic dental injuries occur in childhood and implant treatment should postponed. In this aspect the major problem associated with dental implant placement is the lack of adequate bone volumes at the future time of surgery as such cases receives traumatic dental injury in the early years and disuse atrophy occurs during waiting period. Future trends and strategies in dental traumatology in general and with special attention to dental implant applications are based on the education of population in terms of emergency treatments and urgent transport of patients to the clinics

Explaining the Variation in Tax Structures in the MENA Region

This paper examines the tax structures of the Middle East and North Africa (MENA) countries by focusing on the quality of governance and demographic changes as two influential factors in region’s economies. The objective of is to determine whether these factors can explain the variation in the tax structures of these countries. Results from regressions on the MENA countries and the ones based on a larger sample of 61 countries show that these factors affected the level of taxation, measured by the tax ratio, more strongly than they affected the tax composition. While the quality of governance seems to have affected the tax structures in the MENA countries more than in other comparable Non-OECD countries, demographics seems to have played a bigger role in determining the tax structures in other Non-OECD countries. However, neither of these factors explained changes in the income tax share satisfactorily. One key result is that the increase in the quality of governance has decreased the reliance on domestic taxes on goods and services. The paper provides a discussion on the policy implications of these results.Tax structure, quality of governance, demographics, MENA countries

Externalities from International Labor Migration: Efficacy of a Brain Drain Tax in the Euro-Mediterranean Region

This paper uses a two-region, two-period overlapping generations model with international labor mobility to examine the efficacy of using tax policy to internalize the externalities created by international labor migration. While a brain drain tax has a substantial limiting effect on labor migration and a small negative effect on per worker growth, it is found to be a viable solution to the negative externality problem. It is also found that the brain-drain tax can raise substantial tax revenue for the SMCs which could be used to enhance human capital in the region.International labor mobility, brain-drain tax, population aging, overlapping generations, endogenous tax policy, Euro-Mediterranean region

Barriers to local residents’ participation in community-based tourism: lessons from Houay Kaeng Village in Laos

This study aims to identify the barriers to local residents’ participation in the process of community-based tourism planning and development in a developing country. Focusing on the case of Houay Kaeng Village in Sayabouly Province, Laos, a qualitative exploratory study was conducted by adopting in-depth interviews with the various levels of local community’s members. The key barriers to local community participation identified in this research include: (1) low education levels and lack of knowledge about tourism; (2) poor living conditions and lack of financial support; (3) busy daily routine and lack of time for tourism participation; (4) local community’s perception of tourism as a seasonal business with low income; and (5) power disparities, institutional disincentives and local’s distrust in authorities. The results suggest that only a small number of the local residents in the village were satisfied with their current and on-going participation expressing their strong willingness to continue in participating in the process of tourism planning and development, whereas a large group of the residents were not willing to do it at all in the future. The paper further discusses implications for the government and communities in regard to community-based sustainable tourism development

Global Aging and Fiscal Policy with International Labor Mobility: A Political Economy Perspective

This paper uses an overlapping generations model with international labor mobility and a politically responsive fiscal policy to examine aging in developed and developing regions. Migrant workers change the political structure composed of young and elderly voters in both labor-receiving and labor-sending countries. Numerical simulations show that the developed region benefits more from international labor mobility through the contribution of migrant workers as laborers, savers, and voters. The developing region experiences significant growth in all specifications but benefit more under international capital mobility. Restricting political participation of migrant workers in the developed region produces inferior growth results.population aging, overlapping generations, endogenous fiscal policy, international labor mobility, international capital mobility

Demographic Divide and Labor Migration in the Euro-Mediterranean Region

This paper provides a demographic outlook of the Euro-Mediterranean region and then shows the economic and fiscal consequences of such demographic differences within a two-region model with international labor mobility. International labor mobility is also examined through an externalities framework where brain drain from migration could be taxed by the home countries. Taxing the brain drain has a substantial limiting effect on labor migration and a small negative effect on per worker growth. On the other hand, it could be a solution to the negative externality problem associated with brain drain. It is also found that such tax can raise substantial tax revenue for the SMCs which could be used to enhance human capital in the region.demographic divide, demographic deficit, population aging, youth bulge, labor mobility, brain drain, overlapping generations, endogenous tax policy, Mediterranean region
