The purpose of this paper is to study two native and equal population groups, Finnish speakers and Swedish speakers in Finland, to examine whether there is income variation across couples that differ on ethno-linguistic composition, and if such variation can be attributed to differences in education, educational homogamy and other observable characteristics.

Using detailed register-based household data, the authors estimate OLS models to compare endogamous and exogamous couples with respect to income of the man, the woman, and both partners, respectively.

Endogamous Swedish-speaking couples are found to have on average 25 per cent higher income than other couples. The advantage is not related to differences in educational homogamy, but primarily to man’s income, and roughly half of the income difference is explained by the higher educational level of Swedish-speaking men in endogamous couples. Although women in endogamous Swedish-speaking couples are higher educated than other women, and there is a higher degree of educational homogamy in these couples, their education has only a modest bearing on the income differential.

In the case of Finland, educational homogamy does not affect income variation across native couples that differ on ethno-linguistic composition. Endogamous mate selection seems to increase economic inequality, uphold gender inequality, and help the native minority group in sustaining its own community.

The purpose of this paper is to examine the relative employment levels of return migrants in Finland with regard to their re‐adaptation into the labour market.

Longitudinal census data distinguished Finns who had lived abroad and returned to Finland. These return migrants are compared with non‐migrants with regard to employment levels, using logistic regression models that account for sex, age, education, mother tongue and place of residence.

Both male and female return migrants have odds of employment that are only about half those of their non‐migrant counterparts. The employment differential is stable over time and, consequently, not particularly sensitive to changes in the macroeconomic environment. Relative employment rates of migrants with short periods abroad and long periods in the home country are somewhat higher than those of other migrants, but still lower than those of non‐migrants. Difficulties in readapting into Finnish society are consequently associated with personal characteristics that cannot be observed explicitly but are apparently associated with job‐finding probability.

Considering that Finland at present has no explicit measures directed towards return migrants, it is suggested that this group should be given more policy attention.

The paper provides quantitative evidence that Finnish migrants have substantial difficulties in finding employment in the home country labour market subsequent to return migration, and that these problems cannot be attributed to structural factors.

The chapter presents how business-to-business (B2B) actors may use branding as a tool for maintaining strong, long-term business relationships with their customers. Current knowledge on how to maintain business relationships is presented, related to branding as a tool contributing to long-term and strong business relationships. The phenomenon is studied in detail through a case company, Verso Globe, which operates in the consultancy area and is specialized in sustainability issues. The authors conclude that shared values and norms lead to beneficial business relationships and help maintain them. Also, the case company is closely collaborating and co-creating with its customers, which leads to technological adaptation and increases mutual commitment. A reputation of sharing values, having interest to develop, and co-creating with customers benefits the company and builds the corporate brand. The company culture must, however, support the efforts that make the brand. It is therefore important for B2B actors to understand the customer’s values and use it as a basis for customer relationship management activities. Concurrently, the company’s own values and how it directs employees are elements of its culture, which is the basis for the corporate brand. The perfect match of business relationships is therefore lies in aligning values and norms between the partners.

This paper aims to evaluate the cellular injuries associated with spray‐drying of Lactobacillus rhamnosus GG (LGG) in trehalose/monosodium glutamate (MSG) media by means of flow cytometry measurements; and also whether, and to what extent, the probiotic remain stable and viable in food formulations.

Spray‐drying was applied in the production of trehalose‐based preparations containing LGG. To gain more insights on the cellular damages that must have occurred during drying, flow cytometric analysis was applied in combination with carboxyfluorescein diacetate (cFDA) and PI stains. Spray‐dried samples were observed by scanning electron microscopy (SEM). The storage stability of spray‐dried LGG was monitored in food samples over a period of time.

It was observed that during spray‐drying, 1.80×10⁹ CFU/ml viable counts, which were equivalent of 68.8 per cent cells, were recovered in trehalose matrices but on incorporating 12.5 g/l MSG as a carrier component, survival rates were significantly improved. Density plot analysis showed a higher degree of membrane damage in cells spray‐dried in trehalose without MSG. SEM revealed no difference in the shapes and surfaces of spray‐dried samples. Evaluation of the recovery rates of LGG, initial count of ∼10⁹ CFU/ml or g, at storage time intervals revealed a minimum level of ∼10⁵ CFU/ml in apple juice after 12 days and ∼10⁷ CFU/g in chocolate beverages after ten weeks.

The potential contribution of MSG as a carrier component with trehalose in preventing higher losses during spray‐drying and food storage is pointed out in this study.

Lactobacillus rhamnosus GG, a probiotic of human origin, known to have health beneficial effects can be exposed to osmotic stress when applied in food production as important quantities of sugars are added to the food product. The aim of this study is to assess the mode of action of non‐electrolytes stress on its viability.

Investigations were carried out on stationary phase cells treated with 0‐1.5M sugars, by means of flow cytometric method (FCM) and plate enumeration method. Osmotically induced changes of microbial carboxyfluorescein (cF)‐accumulation capacity and propidium iodide‐exclusion were monitored. The ability of the cells to extrude intracellularly accumulated cF upon glucose energization was ascertained as an additional vitality marker, in which the kinetics of dye extrusion were taken into consideration as well. Sugar analysis by HPLC was also carried out.

The results of FCM analysis revealed that with sucrose, only cells treated at 1.5M experienced membrane perturbation but there was a preservation of membrane integrity and enzymatic activity. There was no loss of viability as shown by plate counts. In contrast, the majority of trehalose‐treated cells had low extent of cF‐accumulation. For these samples a slight loss of viability was recorded on plating (logN/N_o ∼ −0.45). At 0.6M, cells had similar extrusion ability as the control cells upon glucose energization. However, 20 per cent of sucrose‐treated cells and 80 per cent of trehalose‐treated cells extruded the dye in the first 10min.

This finding pointed out the importance of trehalose to enhance the dye extrusion activity, which is regarded as an analogue of the capability of cells to extrude toxic compounds. Sugars exert different effects on the physiological and metabolic status of LGG but none caused a significant viability loss. LGG can be a choice probiotic bacterium in sugar‐rich food production e.g. candies, marmalade etc., in which exposure to high osmotic pressure is be expected.

Optimum balance of intestinal microbiota can be modulated by such dietary means as probiotics and prebiotics. Combination of probiotics and prebiotics could improve the survivality of probiotic candidate due to availability of substrate for its fermentation and confer greater advantages to the host. The purpose of this paper is to examine the potential of prebiotics as functional foods.

The paper explores the selection criteria for prebiotic, their postulated health benefits and safety aspects for their inclusion in infant formula. Potentiality of prebiotics for their exploitation as functional foods has also been delineated.

Probiotics, when applied in conjugation with prebiotics give rise to another possibility in microflora management technique known as synbiotics, which could improve the survivality of probiotic candidate and confer greater advantages to the host. Inclusion of prebiotics like fructo‐oligosaccharide and galacto‐oligosaccharide as infant formula ingredients is suggested. Health benefit properties of prebiotics suggest their application as functional foods.

Ingestion of cultured milk products containing probiotic cultures and prebiotics may provide health benefits in terms of colonization and normalization of intestinal flora and could be recommended for consumption as functional foods.

Increased evidence for the health benefits of probiotics for health restoration coupled with the consumer's inclination towards a safe, natural and cost-effective substitute for drugs have led application of probiotics as a pharmaceutical agent and are rapidly moving in clinical usage. In this context, this article attempts to highlight the potential of probiotics as a pharmaceutical agent.

Endeavor has been made to explore the significance of probiotics for the modulation of gut ecology and their action. Potentiality of probiotics for their exploitation as a pharmaceutical agent has also been justified. Limitations of probiotic therapy and the various considerations for probiotic therapy have also been delineated.

Probiotic organisms influence the physiological and pathological process of the host by modifying the intestinal microbiota, thereby affecting human health. Beneficial effects of probiotics as a pharmaceutical agent seem to be strain and dose dependent and more efficacious with their early introduction. Combination of various probiotics proved to be more efficacious than single strain for exhibiting prophylactic activities.

Reviewed literature indicated that it is difficult to generalize for the beneficial effect of all probiotics for all types of diseases as efficacy of probiotics is strain-dependent and dose-dependent and its clinical application needs long-term investigations.

Clinical trials have displayed that probiotics may alleviate certain disorders or diseases in humans especially those related to gastro-intestinal tract.

Ingestion of fermented dairy products containing probiotic cultures may provide health benefits in certain clinical conditions such as antibiotic-associated diarrhoea, rotavirus-associated diarrhoea, inflammatory bowel disease, inflammatory bowel syndrome, allergenic diseases, cancer, Helicobacter pylori infection and lactose-intolerance. Application of probiotics as a pharmaceutical agent is recommended.
