The Impact of Membership in Strategic Alliances on the Profitability of Firms in the Retail Sector

Strategic alliances in the retail sector are based on cooperation in a variety of activities, ranging from supply and marketing to knowledge sharing and branding. For their members, they are a source of sustainable competitive advantage. Ever since the 1990s, a growing number of firms from the retail sector have attempted to improve their performance through participation in strategic alliances. The objective of this paper is to explore how participation in strategic alliances influences profitability of firms in the retail sector. A dynamic panel analysis is applied to the data on nearly 3,700 firms obtained from Amadeus, a large firm-level database, for eight countries (Croatia, Bosnia and Herzegovina, the Czech Republic, Slovakia, Slovenia, Poland, Hungary and Estonia) for the 2007–2012 period. The results of the investigation suggest that participation in strategic alliances positively influences a firm’s performance

Azijski tigar komarac, Stegomyia albopicta (Aedes albopictus) u Zagrebu i Hrvatskoj (The Asian Tiger Mosquito Stegomyia albopicta (Aedes albopictus) in the City of Zagreb and Croatia)

Stegomyia albopicta (Aedes albopictus) (Skuse, 1894), ili azijski tigrasti komarac, biološki je i zdravstveno značajna vrsta komaraca čije se širenje u svijetu pažljivo prati u posljednjih dvadesetak godina. Prisutna je u susjednoj Italiji (15 godina) i Crnoj Gori (5), stoga je širenje na područje Hrvatske bilo očekivano. Od prvog pronalaska azijskog tigrastog komarca u Zagrebu i Hrvatskoj protekle su dvije godine. Tijekom samo dvije godine tigrasti komarac pronađen je na čitavom području priobalja, od Istre do Dubrovnika. Uspješan u svom naglom širenju i osvajanju novih prostora, zdravstveno značajan kao molestant – napasnik i kao potencijalni prijenosnik različitih arbovirusa i parazita, tigrasti komarac izazvao je zabrinutost javnozdravstvenih i znanstvenih ustanova

An overview of mosquitoes and emerging arboviral infections in the Zagreb area, Croatia

Mosquito control in the Zagreb area has been conducted for many years, whereas the fauna has only been investigated in the last 20 years. So far 30 mosquito species have been detected in the city area. Culex pipiens form molestus is the dominant mosquito species in indoor breeding sites. In forested areas and areas exposed to flooding, the active period is early spring and the dominant species are Ochlerotatus sticticus, Ochlerotatus cantans, Ochlerotatus geniculatus and Aedes vexans. The eudominant mosquito species found in the artificial breeding sites are Culex pipiens and the Asian tiger mosquito, Aedes albopictus. Invasive Ae. albopictus, present in the Zagreb area since 2004, has expanded to a larger area of the city during the last three years. The recent emergence of the human West Nile virus and Usutu virus neuroinvasive disease in Zagreb and its surroundings highlighted the role of mosquitoes as vectors of emerging arboviruses. The paper focuses on mosquito species and arboviral infections detected in humans and animals in the Zagreb area, Croatia

Determinants of Capital Integration among Strategic Alliance Members in the Retail Sector: Evidence from Central and Southeast European Countries

Survival of firms requires continuous search for new and a restructuring of the existing competitive advantages. These can come either from firms’ internal factors or from cooperation with the environment. Cooperation among firms commonly takes place through the formation of strategic alliances. However, such form of cooperation presents only one stage in the integration of business entities. In the long run, strategic alliances can cease to exist or transform into a higher form of association based on capital integration. The objective of this paper is to explore the determinants of capital integration among strategic alliance member firms in retail sectors of several Central and Southeast European countries. Overall, the obtained findings suggest that business entities engage in integration with the aim of reaching hidden knowledge and skills, accessing distribution and supply channels, and developing new products and services. Integration is also driven with the aim of risk diversification and possible better market positioning, achieving the economies of scale, and improving organization and marketing. The opportunistic behavior of partners and limited managerial control represent its strongest barriers

Milk and serum proteomes in subclinical and clinical mastitis in Simmental cows

Bovine mastitis causes changes in the milk and serum proteomes. Here changes in both proteomes caused by naturally occurring subclinical and clinical mastitis have been characterised and quantified. Milk and serum samples from healthy dairy cows (n = 10) were compared to those of cows with subclinical (n = 12) and clinical mastitis (n = 10) using tandem mass tag (TMT) proteomics. Proteins that significantly increased or decreased in milk (n = 237) or serum (n = 117) were quantified and classified by the type of change in subclinical and clinical mastitis. A group of the proteins (n = 38) showed changes in both milk and serum a number of which decreased in the serum but increased in milk, suggesting a particular role in host defence for maintaining and restoring homeostasis during the disease. Proteins affected by bovine mastitis included proteins in host defence and coagulation pathways. Investigation of the modified proteomes in milk and serum was assessed by assays for haptoglobin, serum amyloid A and α acid glycoprotein validating the results obtained by quantitative proteomics. Alteration of abundance patterns of milk and serum proteins, together with pathway analysis reveal multiple interactions related to proteins affected by mastitis. Data are available via ProteomeXchange with identifier PXD022595. SIGNIFICANCE: Mastitis is the most serious condition to affect dairy cows and leads to reduced animal welfare as well as having a negative economic effect for the dairy industry. Proteomics has previously identified changes in abundance of milk proteins during mastitis, but there have been few investigations addressing changes that may affect proteins in the blood during the infection. In this study, changes in the abundance of proteins of milk and serum, caused by naturally occurring mastitis have been characterised by proteomics using a quantitative approach and both subclinical and clinical cases of mastitis have been investigated. In both milk and serum, change in individual proteins was determined and classified into varying types of altering abundance, such as increasing in subclinical mastitis, but showing no further increase in clinical mastitis. Of special interest were the proteins that altered in abundance in both milk and serum which either showed similar trends - increasing or decreasing in both biological fluids or showed reciprocal change decreasing in serum but increasing in milk. As well as characterising proteins as potential markers of mastitis and the severity of the disease, these results provide insight into the pathophysiology of the host response to bovine mastitis

Periosteal Distraction Osteogenesis and Barrier Membrane Application: An Experimental Study in the Rat Calvaria

Background: Distraction of the periosteum results in the formation of new bone in the gap between the periosteum and the original bone. We postulate that the use of a barrier membrane would be beneficial for new bone formation in periosteal distraction. Methods: To selectively influence the contribution of the periosteum, a distraction plate with perforations was used alone or covered by a collagen barrier membrane. All animals were subjected to a 7-day latency period and a 10-day distraction period with a rate of 0.1 mm/day. Four animals per group with or without a barrier membrane were sacrificed at 2, 4, and 6 weeks after the end of the distraction. The height of new bone generated relative to the areas bound by the parent bone and the periosteum was determined by histomorphometric methods. Results: New bone was found in all groups. At the periphery of the distraction plate, significant differences in bone height were found between the hinge and the distraction screw for the group without barrier membrane at 2 weeks (0.39 ± 0.19 mm) compared to 4 weeks (0.84 ± 0.44 mm; P = 0.002) and 6 weeks (1.06 ± 0.39 mm; P = 0.004). Differences in maximum bone height with and without a barrier membrane were observed laterally to the distraction plate at 2 weeks (1.22 ± 0.64 versus 0.55 ± 0.14 mm; P = 0.019) and 6 weeks (1.61 ± 0.56 versus 0.73 ± 0.33 mm; P = 0.003) of the consolidation period. Conclusion: Within the limitations of the present study, the application of a barrier membrane may be considered beneficial for new bone formation induced by periosteal distraction
