Sectoral resilience through learning in networks and GVCs: A historical perspective on the food-processing and clothing industries in Poland
This paper investigates how inter-organizational learning in networks and global value chains (GVCs) has contributed to resilience in Poland's food processing and clothing industries. The Polish economy has been widely accepted as resilient since Poland's transition from a planned to a market economy. Through drawing on the regional resilience literature, this paper develops a network-oriented framework of sectoral resilience that integrates network evolution, inter-organizational learning in networks, and the role of history. It uses unique primary data from the period of Poland's abovementioned transition (1989–2001), which is complemented with secondary data on the networking activities of Polish firms in the two abovementioned sectors between 2004 and 2018. In turn, the firms' interactive learning is found to function as an important contributor to their path-dependent network trajectories and resilience. Moreover, knowledge networks and GVCs present different dynamics in terms of their effects on learning and result in uneven sectoral resilience. Learning from knowledge spillovers and by interacting with the co-existence of adaptation- and adaptability-related network characteristics has guided both the studied sectors towards developing short-term adaptive capacity for path-extension and sustainability. Learning from advanced science and technology (S&T) and education regarding exclusive adaptability-related network characteristics has driven Poland's food-processing industry's path-evolving long-term capability to be fully resilient
Effects of different raising systems on colour and quality characteristics of Turkish Pekin duck meats
The current trial was conducted to determine the influence of different raising systems on the meat quality properties of male Turkish Pekin ducks. Ninety male ducklings were randomly allocated to three experimental groups: an animal-fish integrated farming group (IG), a non-animal-fish integrated farming group (NIG) and a poultry house group (PHG). All ducklings were fed a starter diet from weeks 2 to 6 and a finisher diet from weeks 6 to 10. Feed and water were offered ad libitum. At the end of the trial all ducks were slaughtered and the carcasses were stored at 3 °C for 24 hours, after which L*, a* and b* values of the carcass skins were measured. After standard dissection of carcasses, pectoralis muscles were obtained on which pH, colour (L*, a*, b*, C and H), total aerobic mesophilic, total aerobic psychrotrophic, lactic acid bacteria, Micrococcus/Staphylococcus, yeast-mould and Enterobacteriaceae counts were determined. The different raising systems of the ducks had significant effects on the pH, total aerobic mesophilic, Enterobacteriaceae, and L* and b* values of the pectoralis muscle. The lowest pH, total aerobic mesophilic and Enterobacteriaceae counts were found in the PHG group. The lowest L* values for the pectoralis muscle were found in the IG group while the highest a* value was recorded in the IG group. Significant differences in skin colour were observed between the experimental groups. For all production groups, all microbial counts were found to be within acceptable ranges. However, pH, total aerobic mesophilic and Enterobacteriaceae results were found to be lower in the PHG group than in the other groups. Different raising systems were thus found to affect the meat and skin colour of ducks, which may influence the preference of consumers.

Antitumor effect of sFlt-1 gene therapy system mediated by Bifidobacterium Infantis on Lewis lung cancer in mice
Soluble fms-like tyrosine kinase receptor (sFlt-1) is a soluble form of extramembrane part of vascular endothelial growth factor receptor-1 (VEGFR-1) that has antitumor effects. Bifidobacterium Infantis is a kind of non-pathogenic and anaerobic bacteria that may have specific targeting property of hypoxic environment inside of solid tumors. The aim of this study was to construct Bifidobacterium Infantis-mediated sFlt-1 gene transferring system and investigate its antitumor effect on Lewis lung cancer (LLC) in mice. Our results demonstrated that the Bifidobacterium Infantis-mediated sFlt-1 gene transferring system was constructed successfully and the system could express sFlt-1 at the levels of gene and protein. This system could not only significantly inhibit growth of human umbilical vein endothelial cells induced by VEGF in vitro, but also inhibit the tumor growth and prolong survival time of LLC C57BL/6 mice safely. These data suggest that Bifidobacterium Infantis-mediated sFlt-1 gene transferring system presents a promising therapeutic approach for the treatment of cancer

Productive Development Policies in Latin American Countries: The Case of Peru, 1990-2007
This paper assesses the institutional setting and productive impact of selected productive development policies (PDPs), institutions, and programs implemented in Peru during the period 1990-2007. The assessment is based on a simple, basic framework of a series of economic or market failures that may have constrained the transformation of the productive structure, the process of innovation, and the growth of total factor productivity. Evidence indicates that the PDPs and structural reforms implemented in Peru did not significantly alter the productive structure of the Peruvian economy. If the objectives of the PDPs are to transform the productive structure, increase total factor productivity, and enhance innovation, government interventions need to focus directly on the source of market failures and create quality productive changes within the private sector
