Socioeconomic condition and dietary habits in relation to oral health in 12-year-old children from Sarajevo, Bosnia-Hercegovina

Introduction: Living conditions and socioeconomic status are the significant determinants of oral health. The research goal was to analyze the dietary habits of 12-year-old children in Sarajevo, Bosnia-Hercegovina. Another goal was to investigate the differences in food cariogenicity of children living under different socioeconomic conditions and to determine their relationship with the oral health. Materials and methods: The sample included 109 children, classified in groups of high, average and low socioeconomic status. Based on the survey and examination, data on nutrition and caries experience (DMFT index) were obtained. Results: There was a difference in dietary habits between children living under different conditions. Children of high socioeconomic status (SES) had a more favorable number of daily meals comparing to children of low socioeconomic status. The average DMFT index, as a measure of caries experience of 12-year-old children amounted 4.8(±3.2). Children of high socioeconomic status had significantly lower caries experience than those from average and low statuses (high SES DMFT 3,60±2,84SD vs. middle SES DMFT 5,28±3,83SD and low SES DMFT 5,47±2,53SD; p<0.05)

Business-to-business open innovation: COVID-19 lessons for small and medium-sized enterprises from emerging markets

Small and medium-sized enterprises (SMEs) from emerging markets are the most vulnerable types of firms, especially in times of crisis due to time and resource constraints. Thus, this paper aims to help SMEs from emerging markets in choosing the right business partners with whom to cooperate to develop relevant innovations in crisis periods in general, and during the COVID-19 pandemic in particular. To obtain relevant insights, qualitative data from SMEs in Bosnia and Herzegovina were collected in March-April 2020. The findings show that SMEs have embraced new collaborations with business customers and competitors, and developed a collaborative mindset opposed to the traditionally competitive way of doing business in emerging markets. Based on the findings, this paper presents a set of recommendations for managers, and suggests several future research opportunities around the management of openness in the context of SMEs from emerging markets

A Review of the Scattering-Parameter Extraction Method with Clarification of Ambiguity Issues in Relation to Metamaterial Homogenization

The scattering-parameter extraction method of metamaterial homogenization is reviewed to show that the only ambiguity is that related to the choice of the branch of the complex logarithmic function (or the complex inverse cosine function). It is shown that the method has no ambiguity for the sign of the wavenumber and intrinsic impedance. While the method indeed yields two signs for the intrinsic impedance and thus the wavenumber, the signs are dependent. Moreover, both sign combinations lead to the same permittivity and permeability, and are thus permissible. This observation is in distinct contrast to a number of statements in the literature where the correct sign of the intrinsic impedance and wavenumber resulting from the scattering-parameter method is chosen by imposing additional physical requirements, such as passivity. The scattering-parameter method is reviewed through an investigation of a uniform plane wave normally incident on a planar slab in free space. The severity of the branch ambiguity is illustrated through simulations of a known metamaterial realization. Several approaches for proper branch selection are reviewed, and the suitability to metamaterial samples is discussed. ©2013 IEEE

Organization and Product Design Pairings: A Review of Product Innovation Capabilities, Conceptualization and Future Directions

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Drawing on the Resource-based view of firms and market orientation theory, this paper presents a complementary view of the influence of product innovation capabilities (PICs) on organization and product design pairings. By exploring the influence of three complementary factors; market orientation, organizational form, and managerial strategic decisions, as essential determinants for emergence of architectural pairings, we theorize that PICs lead to better; organization and product design pairings selection, unique customer benefits, market acceptance, significant cost reductions, and new products development, and consequently superior organizational performance. We propose in essence, that PICs significantly shape and determine the success of architectural pairings between organization and product designs, and act as a source of sustainable competitive advantage for organizations. We further identify scope for future research to evaluate measures and validity of product innovation capability dimensions, and the extent of influence of the identified factors on architectural pairings
