Social aspects of organic agriculture and other multifunctional benefits - Successful EU models compared with possibilities for organic developments in Croatia

Main objective of the dissertation is to illustrate how social and educational aspects (in close interaction with other multifunctional aspects in organic agriculture) which are developed on different multifunctional organic farms in Italy and Netherlands, as well as established agricultural policy frameworks in these countries, can be compared with the situation in Croatian organics and can contribute to further developent of organic issues in the Repubic of Croatia. So, through different chapters, the dissertation describes the performance of organic agriculture sectors in Italy, Netherlands and Croatia within the national agricultural policy frameworks, it analyzes the role of national institutions and policy in Croatia in connection with Croatia's status of candidate country for enterance into EU and harmonization of legislation with the CAP, as well as analyzes what is the role of national authorities, universities, research centres, but also of private initiatives, NGOs and cooperatives in organic agriculture in Netherlands, Italy and Croatia. Its main part describes how social and educational aspects are interacting with other multifunctional aspects in organic agriculture and analyzes the benefits and contribution of multifunctional activites performed on organic farms to education, healthy nourishment, environment protection and health care. It also assess the strengths and weaknesses of organic agriculture in all researched countries. The dissertation concludes with development opportunities for multifunctional organic agriculture in Croatia, as well as giving perspectives and recommendations for different approaches on the basis of experiences learned from successful EU models accompanied with some personal ideas and proposals.

An Input-Process-Output Approach to Interorganizational Teams: The Influence of Work Group Diversity, Trust and Shared Leadership on Communication Network and Team Outputs.

The market’s challenges bring firms to collaborate with other organizations in order to create Joint Ventures, Alliances and Consortia that are defined as “Interorganizational Networks” (IONs) (Provan, Fish and Sydow; 2007). Some of these IONs are managed through a shared partecipant governance (Provan and Kenis, 2008): a team composed by entrepreneurs and/or directors of each firm of an ION. The research is focused on these kind of management teams and it is based on an input-process-output model: some input variables (work group’s diversity, intra-team's friendship network density) have a direct influence on the process (team identification, shared leadership, interorganizational trust, team trust and intra-team's communication network density), which influence some team outputs, individual innovation behaviors and team effectiveness (team performance, work group satisfaction and ION affective commitment). Data was collected on a sample of 101 entrepreneurs grouped in 28 ION’s government teams and the research hypotheses are tested trough the path analysis and the multilevel models. As expected trust in team and shared leadership are positively and directly related to team effectiveness while team identification and interorganizational trust are indirectly related to the team outputs. The friendship network density among the team’s members has got positive effects on the trust in team and on the communication network density, and also, through the communication network density it improves the level of the teammates ION affective commitment. The shared leadership and its effects on the team effectiveness are fostered from higher level of team identification and weakened from higher level of work group diversity, specifically gender diversity. Finally, the communication network density and shared leadership at the individual level are related to the frequency of individual innovative behaviors. The dissertation’s results give a wider and more precise indication about the management of interfirm network through “shared” form of governance.

Entomological monitoring in the cultural heritage facilities as prerequisite for a successful IPM programme

The European Committee for Standardization is working on a standard for the application of IPM (Integrated Pest Management) in museums and cultural heritage facilities. Since one of the aims of this research was to verify the approach against pests adopted in Italian conservation facilities, a survey was conducted. The results show that for the Italian museums, archives, libraries and historical houses pests are a problem, but IPM is unknown and prevention programmes to avoid damages caused by them, are not applied. In the most of cases pests problems are solved only when the risk is high and damages are visible. Also entomological monitoring, which represents a crucial part of IPM and could be very useful, is not included among the ordinary prevention activities. In addition, at present, the scientific researches on entomological traps, whether light or pheromones, for “cultural heritage pests” is extremely poor and only recently the behaviour and/or the physiology of the insects “of museums” have been investigated. For these reasons, tests to increase the traps using are performed. In particular, S. paniceum behaviour towards different attraction systems was investigated and the results indicate that the light traps efficiency could be improved using specific wavelengths and light sources.

"Unser Volk ist vereint, unser Land unabhängig" - zum Umgang mit nationalen Identitätsmodellen im postsowjetischen Kasachstan

Für alle fünf zentralasiatischen Teilrepubliken kam der Zusammenbruch der Sowjetunion im Jahr 1991 relativ plötzlich und eher unerwartet. Der Prozess der „Transformation“ beinhaltete für die neu entstandenen Staaten nun nicht nur die Umstellung politischer und wirtschaftlicher Systeme, sondern ebenso die Organisation von Erinnerung und die Konstruktion von Identität, bei der die staatliche Nationalisierungspolitik oft Paradebeispiele von invented traditions her-vorbrachte. rnIn Kasachstan, dem Land, das während der Sowjetzeit am stärksten russifiziert wurde und heute offiziell 120 Minderheiten zählt, stellt sich dabei die Frage, wie nationale Identitätsmus-ter konstruiert werden und wie Politik. Medien und Bevölkerung damit umgehen. Zwanzig Jahre nach der Unabhängigkeitserklärung des Landes und einer Phase, in der die Regierung mit einer Vielzahl von Maßnahmen versucht, den Identitätsfindungsprozess zu steuern, wurde im Rahmen dieser Arbeit erstmals eine empirische Studie zu der Frage durchgeführt, welche Bedeutungen bestimmte Identitätskonzepte für die lokale Bevölkerung haben. Während meh-rerer Forschungsaufenthalte von insgesamt vier Monaten in den Jahren 2010 und 2011 wurden in Hinblick auf die Fragestellung leitfadenorientierte Interviews und informelle Gespräche mit Teilen der kasachstanischen Bevölkerung geführt, teilnehmende Beobachtung, zwei Fragebo-genaktionen und eine Zeitungsanalyse durchgeführt sowie wissenschaftliche Studien und poli-tische Dokumente analysiert.rnDie Arbeit kommt zu dem Ergebnis, dass die Mehrheit der Befragten sich mehr oder weniger stark entweder über die Staatsbürgerschaft oder die ethnische Zugehörigkeit zur Titularnation mit dem Staat identifiziert. Auffällig ist die Bedeutung regionaler Identitäten für die Befrag-ten, die weder in der nationalen Identitätspolitik noch in der wissenschaftlichen Literatur von Wichtigkeit sind. Ethnische und religiöse Nivellierungen scheinen im Alltagsleben belanglos zu sein, aber in bestimmten anderen Kontexten eine entscheidende Rolle zu spielen. Starke Unterschiede in der Bedeutung verschiedener Identitätsmodelle lassen sich zwischen Stadt- und Landbevölkerung beziehungsweise zwischen sowjetisierten und nach der Wende repatri-ierten Kasachen ausmachen.rnEs ist anzunehmen, dass die Regierung der entscheidende Agent in der Identitätsfindung des Landes ist. Unter den Befragten zeigte sich, dass Identitätspolitik auf der pragmatischen Ebe-ne, beispielsweise in der Anerkennung von Russisch und Kasachisch als Staatssprachen, er-folgreicher ist als auf der emotionalen. rn

Specific nail alterations in cutaneous T-cell lymphoma: successful treatment with topical mechlorethamine

Cutaneous T-cell lymphoma can be associated with clinically significant nail alterations, the presentation of which can be protean and misleading. To date, only a few reports have demonstrated direct specific tumor infiltration of the nail bed, while little is known about the efficacy of topical treatments.

Cellular immune responses to HCV core increase and HCV RNA levels decrease during successful antiretroviral therapy

Background Hepatitis C virus (HCV) infection is a major cause of morbidity in HIV infected individuals. Coinfection with HIV is associated with diminished HCV-specific immune responses and higher HCV RNA levels. Aims To investigate whether long-term combination antiretroviral therapy (cART) restores HCV-specific T cell responses and improves the control of HCV replication. Methods T cell responses were evaluated longitudinally in 80 HIV/HCV coinfected individuals by ex vivo interferon-γ-ELISpot responses to HCV core peptides, that predominantly stimulate CD4+ T cells. HCV RNA levels were assessed by real-time PCR in 114 individuals. Results The proportion of individuals with detectable T cell responses to HCV core peptides was 19% before starting cART, 24% in the first year on cART and increased significantly to 45% and 49% after 33 and 70 months on cART (p=0.001). HCV-specific immune responses increased in individuals with chronic (+31%) and spontaneously cleared HCV infection (+30%). Median HCV RNA levels before starting cART were 6.5 log10 IU/ml. During long-term cART, median HCV-RNA levels slightly decreased compared to pre-cART levels (−0.3 log10 IU/ml, p=0.02). Conclusions Successful cART is associated with increasing cellular immune responses to HCV core peptides and with a slight long-term decrease in HCV RNA levels. These findings are in line with the favourable clinical effects of cART on the natural history of hepatitis C and with the current recommendation to start cART earlier in HCV/HIV coinfected individuals.

Sperm analysis of patients after successful treatment of childhood acute lymphoblastic leukemia with chemotherapy

Survivors of childhood acute lymphoblastic leukemia (ALL) treated with radiotherapy are at risk for impaired fertility. Whether chemotherapy alone is also long-term gonadotoxic is unclear. We assessed gonadal function in 11 male ALL-survivors treated with the same chemotherapy regimen and compared sperm analysis to healthy men. While sex hormone levels were normal in all subjects, 5/11 survivors showed pathological sperm concentration and 4/11 a decreased total sperm count compared to WHO criteria. Compared to healthy controls, all quantitative parameters in semen analysis of survivors were decreased. This suggests that treatment with chemotherapeutic agents alone, even in moderate doses, might have a gonadotoxic effect.

Nail Lichen Planus: Successful Treatment with Etanercept

BACKGROUND: Etanercept is a fully human tumor necrosis factor a receptor fusion protein that binds tumor necrosis factor a with greater affinity than natural receptors. Biologics are widely used in the treatment of psoriasis and psoriasis arthritis and may represent a new therapeutic option for some patients with psoriatic nail disease. CASE REPORT: We report a case of lichen planus limited to the toe nails successfully treated with etanercept monotherapy. CONCLUSION: The significant improvement of our case suggests that etanercept is an effective treatment modality for lichen planus limited particularly to the nails. Further controlled studies are needed to establish the effectiveness and therapeutic regimes.
