The Governance of Rural Regional Learning and Innovation - Towards an analytical and relfexive research framework
Low motivation and unawareness in small farmers as an obstacle for implementation of the EU pig welfare rules
Using semi-structured interviews, Croatian pig farmers and institutional stakeholders were asked about their intentions to improve pig welfare, future perspectives, opinions and communication efforts on the EU pig welfare directives. While full-time family farmers (FFF) and employees at farm enterprises (EFE) expressed interest in improving pig welfare on their farms as a prerequisite for increasing competitiveness in the future, part-time family farmers (PFF) were not interested in pig welfare because they did not want to increase productivity and feared for their existence. Communication between institutional stakeholders and FFF with more than ten sows is best stablished, whereas communication with EFE is more via private consultants and communication with PFF is lacking. As Croatia is today counting over 85% farms as production units with up to 10 sows covering 75% of whole pig production, these results represent considerably important indicators of necessity to approach this population of farmers
Harmonization of welfare standards for the protection of pigs with the EU-rules: the case of Croatia
Three quarters of Croatian pigs are produced in small production units (1-5 sows) and on family farms with mixed farming activities. Only few farms have specialized production units with up-to-date technologies and comply with EU standards. The future competitiveness of Croatian pig production is therefore questionable unless production systems are changing. Modernisation will most probably result in the expansion and intensification of larger farms and the termination of a great number of small farms. The aim of this study was to investigate how the welfare of pigs on Croatian farms would be affected by modernisation. Seventeen Croatian pig farmers were interviewed to describe the different pig production systems, while the welfare of pigs was assessed using resource-based and animal-based welfare indicators. Three production systems were distinguished: part-time family farms (PFF), full-time family farms (FFF) and farm enterprises (FE). Resources-based welfare indicators were investigated in 17 pens located on seven PFF, 25 pens distributed across six FFF and seven pens were visited at two FE. Animal-based welfare indicators were assessed on 21 pigs at PFF, 90 pigs at FFF and 18 pigs at FE. The study demonstrated that different production systems have different welfare problems. Based on resource-based indicators pig welfare was better ensured on FE, but based on animal-based indicators there was no clear difference in welfare between the three production systems. Based on these findings is it unlikely that the modernisation of current production systems in Croatia will significantly improve pig welfare. From a welfare point of view, neither the enlargement nor the termination of pig farms can be supported. However, the number of farms involved in this study was too small to allow for generalisation. The case-study does, however, point at the importance of further studies into the specific welfare problems of each of the production-systems and their different solutions. These studies should be of larger scale in order to get a representative picture of pig welfare in Croatia, and its assurance within the process of modernisation
Deliverable 4.2 Support of joint learing and innovation in grassroots development initiatives: operational quality of arrangements
Well-working operational interfaces : a key to more collaborative modes of governance
This thesis contributes to more collaborative forms of governance in rural areas. It contains an analysis of arrangements underlying existing forms of collaboration and focuses particularly on the ways in which these forms of collaboration are supported. The study was carried out in six European rural areas
An integrated perspective on rural regional learning
Regional learning and innovation is a key to promote more resilient, robust and inclusive rural areas. Current analytical frameworks focus on support for knowledge spill-over from academia to industry and sector-oriented learning. The high diversity of actors and activities contributing to rural regional development is thereby not addressed. In this paper, existing frameworks are revised to offer an integrated perspective on the support for rural regional learning. The revised framework is used to identify, map and analyse supportive arrangements and their operational interfaces. It also offers an analytical perspective for beneficiaries to evaluate the support received. The DERREG case study area Westerkwartier is used to illustrate the use of the revised framework and its relevance for empirical research. The revised framework can be used to compare supportive arrangements for learning across different rural region
The role of leadership in place-based development and building institutional arrangements
In various case studies across Europe the vital role of rural place leadership in enabling a place-based approach to local and regional development has been highlighted, although not always explicitly addressed as such. This paper aims to do so by reviewing the findings from a selection of earlier research projects within a framework of the role of rural leadership in place-based development. Building on the increasing body of literature on place leadership, the review reveals how place leadership in rural areas is performed by varied public, private and civic actors; is able to bridge vested stakes and make new connections; is supportive to joint learning and innovation and an increasing range of bottom-up grassroots initiatives. Effective rural place leadership initiates joint reflection and enforces a collaborative spirit resulting in an expanding spiral of new alliances and new (institutional) arrangements. This underpins the importance of rural place leadership in building collective agency and its capacity to better attune the institutional setting to the specificities of place and thus enhance place-based development
Gene expression analysis after receptor tyrosine kinase activation reveals new potential melanoma proteins
<p>Abstract</p> <p>Background</p> <p>Melanoma is an aggressive tumor with increasing incidence. To develop accurate prognostic markers and targeted therapies, changes leading to malignant transformation of melanocytes need to be understood. In the <it>Xiphophorus </it>melanoma model system, a mutated version of the EGF receptor Xmrk (<it>Xiphophorus </it>melanoma receptor kinase) triggers melanomagenesis. Cellular events downstream of Xmrk, such as the activation of Akt, Ras, B-Raf or Stat5, were also shown to play a role in human melanomagenesis. This makes the elucidation of Xmrk downstream targets a useful method for identifying processes involved in melanoma formation.</p> <p>Methods</p> <p>Here, we analyzed Xmrk-induced gene expression using a microarray approach. Several highly expressed genes were confirmed by realtime PCR, and pathways responsible for their induction were revealed using small molecule inhibitors. The expression of these genes was also monitored in human melanoma cell lines, and the target gene <it>FOSL1 </it>was knocked down by siRNA. Proliferation and migration of siRNA-treated melanoma cell lines were then investigated.</p> <p>Results</p> <p>Genes with the strongest upregulation after receptor activation were FOS-like antigen 1 (<it>Fosl1</it>), early growth response 1 (<it>Egr1</it>), osteopontin (<it>Opn</it>), insulin-like growth factor binding protein 3 (<it>Igfbp3</it>), dual-specificity phosphatase 4 (<it>Dusp4</it>), and tumor-associated antigen L6 (<it>Taal6</it>). Interestingly, most genes were blocked in presence of a SRC kinase inhibitor. Importantly, we found that <it>FOSL1</it>, <it>OPN</it>, <it>IGFBP3</it>, <it>DUSP4</it>, and <it>TAAL6 </it>also exhibited increased expression levels in human melanoma cell lines compared to human melanocytes. Knockdown of <it>FOSL1 </it>in human melanoma cell lines reduced their proliferation and migration.</p> <p>Conclusion</p> <p>Altogether, the data show that the receptor tyrosine kinase Xmrk is a useful tool in the identification of target genes that are commonly expressed in Xmrk-transgenic melanocytes and melanoma cell lines. The identified molecules constitute new possible molecular players in melanoma development. Specifically, a role of FOSL1 in melanomagenic processes is demonstrated. These data are the basis for future detailed analyses of the investigated target genes.</p
