Does Immigration Hurt Low Income Workers?: Immigration and Real Wage Income below the 50th Percentile, Sweden 1993-2003

This paper addresses potential effects of immigration on wage income of predominantly low income Swedish born workers. Using unique individual full population panel data for two time-periods, 1993- 1999 and 1997-2003, we estimate two fixed effect models controlling for both individual and local labor market characteristics as well as individual and regional fixed effects. The models are tested for a range of population sub-groups, the compulsory and upper secondary educated and workers within certain shares of the local income distribution (using different below median percentile levels as population cut-off points). The estimates show mainly a positive relationship between increasing shares of foreign born and wage income of Swedish born workers.International migration; Local labor markets; Wage levels; labour supply

Energy Consumption Analysis, Efficiency Measures and Renewable Energy Investments Towards a Nearly Net-Zero Campus: The Case Study of Cyprus International University

According to the International Energy Agency, energy and process emissions from buildings are responsible for nearly 33 % of global CO2 emissions in 2021; with two other leading sectors; transportation and industry with emissions of 22 % and 30 %, respectively. As a result, parallel with global signs of progress, the topic of energy efficiency and energy management in buildings has come to be a rule of energy policy in Cyprus International University (CIU) buildings. In Cyprus, similar to the reference of IEA, nearly 30% of the energy consumption is from the buildings, which is the most open to energy-saving measures. Since 2017, Sustainable Energy Research Centre in CIU has been working on the energy measures of CIU on both supply and demand sides. To increase the university’s sustainability further in the Energy and Climate section of both UI GreenMetrics and contribution to UN Sustainable Development Goals, conscious energy steps are taken both in energy saving and alternative renewable energy sources in the whole campus which resulted in making CIU a leading example of a sustainable university campus in the Middle-East as it holds the 3rd place for the most sustainable university campus in the region according to UI GreenMetrics World Sustainable University Ranking in 2022. In this paper, an energy audit study will be presented which evaluates the total energy load and energy-saving potential on campus and propose measures that should be taken. In order to conduct this study, Education and Humanities (EH) Building is taken as the pilot study which considers a detailed audit and actions to minimize energy consumption. Then the findings obtained from this energy efficiency study are generalized to all existing buildings on the campus and the expected effect of energy efficiency attempts is projected. These results are joined with the future alternative energy projects planned on the campus and the roadmap to nearly net-zero campus is discussed at the end of the study

Optimal Health Insurance in the Presence of Risky Health Behaviors *

Abstract In this paper I develop an overlapping generations model that incorporates bad behaviors (such as smoking and unhealthy eating habits that lead to obesity) to investigate the equilibrium effects of different cost sharing mechanisms and excise taxation on bad behaviors and medical expenditures. I show that while higher cost sharing induces individuals to refrain from bad behaviors, it has mixed welfare effects across different individuals. For example, if coinsurance rate is increased by 20 percentage points, smoking prevalence goes down by about 2 percentage points and medical expenditures to GDP ratio slightly declines. Although higher cost sharing increases the overall welfare in the economy, unhealthy individuals are either worse off or have much less welfare gains compared to healthy individuals. The quantitative implications of the model are consistent with the variation in smoking prevalence and excise taxes across tobacco and non-tobacco states

DFT study of the mechanism and stereochemistry of electrophilic transannular addition reaction of bromine to 6-oxa-heptacyclo[9.6.2.23,9.113,16.02,10.04,8.012,17]docosan-14,18,20-triene-12,17-dicarboxylic anhydride

The geometry and the electronic structure of 6-oxa-heptacyclo[9.6.2.23,9.113,16.02,10.04,8.012,17] docosan-14,18,20-triene-12,17-dicarboxylic anhydride (HDTD) have been investigated by DFT methods. The study shows that the norborneyl double bond of the HDTD molecule is endo pyramidalized and the central and bicyclo[2,2,2]octenyl double bonds are exo pyramidalized. The structure and stability of the cation intermediates and products of the reaction have been investigated by DFT methods. The most stable cation intermediate is U-N-type ion and the reaction takes place over this cation. The cation centre of U-N-type ion mutually interacts with the unshared electron pair of the oxygen atom of the tetrahydrofuran ring on the exo face and is sterically hindered by the tetrahydrofuran ring. The nucleophilic attack of bromide anion (Br–) on the cation centre of U-N-type ion occurs on the endo face and as a result the exo,endo-dibromide isomer of U-N-type product is obtained, which is 6.913 kcal mol-1 more stable than the exo,exo-isomer.

The Influence of Hyperbaric Oxygen Treatment on the Healing of Experimental Defects Filled with Different Bone Graft Substitutes

To assess potential effects of hyperbaric oxygen (HBOT) on artificial bone grafts, β - Tricalcium phosphate (β-TCP) and calcium phosphate coated bovine bone (CPCBB) substitutes were applied to standard bone defects in rat tibiae. The control defects were left empty. Half of the animals received 60 minutes of 2.4 atmosphere absolute (ATA) of HBOT. Rats were sacrificed at one, two and four weeks. Bone healing was assessed histologically and histomorphometrically using light microscopy. The periosteum over the bone defects was examined ultrastructurally. Cardiac blood was collected to determine the serum osteocalcin levels. The HBOT increased new bone formation in the unfilled controls and β-TCP groups and significantly decreased cartilage matrix and fibrous tissue formations in all groups. Active osteoblasts and highly organized collagen fibrils were prominent in the periosteum of β-TCP and control groups. Serum osteocalcin levels also increased with HBOT. The healing of defects filled with CPCBB was similar to the controls and it did not respond to HBOT. These findings suggested that the HBOT had beneficial effects on the healing of unfilled bone defects and those filled with β-TCP bone substitute but not with CPCBB, indicating a material-specific influence pattern of HBOT

Birth and Employment Transitions of Women in Turkey: Conflicting or Compatible Roles?

The relationship between fertility and employment among women is a challenging topic that requires further exploration, especially for developing countries where the micro and macro evidence fails to paint a clear picture. This study analyzes the two-way relationship between women’s employment and fertility in Turkey using a hazard approach with piece-wise constant exponential modelling, using data from the 2008 Turkey Demographic and Health Survey. To the best of the authors’ knowledge, this is the first study that makes use of an event history analysis to analyze this relationship within a developing country context. Specifically, a separate analysis is made of the association between the employment statuses of women in their first, second, third, and fourth and higher order conceptions, and the association of fertility and its various dimensions with entry and exit from employment. The findings suggest that a two-way negative association exists between fertility and employment among women in Turkey, with increasing intensities identified among some groups of women. Our findings also cast light on how contextual changes related to the incompatibility of the roles of worker and mother have transformed the fertility-employment relationship in Turkey, in line with propositions of the role incompatibility hypothesis.

Possible Medical Aetiological Factors and Characteristics of Molar Incisor Hypomineralisation in a Group of Turkish Children

Svrha: Željele su se odrediti kliničke značajke i mogući medicinski uzroci molarno incizivne hipominerelizacije (MIH-a) u skupini turske djece. Materijali i metode: U ispitivanju je sudjelovalo 228 djece u dobi od 7 do 14 godina. Svi su pregledani na Odjelu za dječju dentalnu medicinu Stomatološkog fakulteta Sveučilišta Marmara u Istambulu. Prenatalni i postnatalni podatci prikupljeni su popunjavanjem upitnika. Rezultati: MIH je pronađen kod 54 (24 %) djeteta, a 41 (76 %) imalo je samo ograničena područja opaciteta (1. stupanj). Kod osam (15%) djevojčica i dječaka bile su obavljene atipične restauracije (2. stupanj), a barem jedno posteruptivno ljuštenje (3. stupanj) uočeno je kod njih pet (9 %). MIH je svima uglavnom zahvaćao kutnjake (55 %), a ne sjekutiće (45 %; p<0,001). U skupini s MIH-om bili su česti prenatalni bronhitis i hipertenzija. Nije bilo veće razlike u medicinskoj anamnezi do dobi od tri godine između skupine s MIH-om i skupine bez njega, osim duljeg uzimanja lijekova i astme u skupini s molarno incizalnom hipomineralizacijom (p<0,05). Zaključak: Premda etiologija MIH-a ostaje nejasna, čest je kod djece koja neprekidno uzimaju lijekove i oboljela su od astme u prve tri godine života.Objective: To determine the clinical characteristics and possible medical causes of molar incisor hypomineralisation (MIH) in a group of Turkish children. Materials and Methods: A total of 228 children aged 7–14 years were examined in the Department of Paediatric Dentistry Dental School of Marmara University. Prenatal and postnatal medical data were recorded using a questionnaire. Results: MIH was observed in 54 (24%) children, 41 (76%) of whom had only demarcated opacities (grade 1). Eight (15%) children had atypical restoration (grade 2), and at least one post-eruptive breakdown (grade 3) was observed in five (9%) children. MIH affected molars (55%) more frequently than incisors (45%; P < 0.001). Prenatal bronchitis and hypertension were frequent in the MIH group. No significant difference in medical history during the first 3 years of life was observed between the MIH and non-MIH groups, except prolonged medicament consumption and asthma in the MIH group (P < 0.05). Conclusion: Although the aetiology of MIH remains unclear, constant medicament consumption and asthma during the first 3 years of life were reported frequently in children with MIH
