Development of the profession and qualifications of adult educators in Lithuania in the context of reforms of adult education

The Baltic countries regained their independence from the Soviet Union in the early 1990s and joined the European Union in 2004. This article seeks to explore institutional development and reforms of adult education and lifelong learning in Lithuania with respect to the processes, the actors and the context of socioeconomic change over the past 20 years. It also looks at the implications of these processes for the professionalisation of adult educators, referred to here as “adult learning teachers” (ALTs). The authors begin with an analysis of the historical-institutional and political-economical aspects of the development of adult education and lifelong learning by providing a retrospective of institutional change in Lithuania. They then move on to analyse the existing institutional and legal arrangements of adult education which shape and institutionalise the profession and qualifications of ALTs. Their empirical research reveals the opinions of Lithuanian ALTs on their current professional occupational profile and its future development.     

A novel way of liver preservation improves rat liver viability upon reperfusion

Background/aim： Currently, the liver is cold-preserved at 0-4 ℃ for experimental and clinical purposes. Here, we investigated whether milder hypothermia during the initial phase of the preservation period was beneficial for liver viability upon reperfusion. Methods： In the first set of experiments, rat livers were preserved either conventionally in clinically used histidine-trypthopan-ketoglutarate （HTK） solution （Group A： 45 min and Group B： 24 h） or by slow cooling HTK solution （from 13 ℃ to 3 ℃） during the initial 45 min of preservation （Group C： 24 h）. In the second set of experiments, additional groups of livers were evaluated： Group BB-preservation according to Group B and Group CC-preservation according to Group C. Further, some livers were preserved at 13 ℃ for 24 h. Livers were then reperfused using a blood-free perfusion model. Results： Bile production was approximately 2-fold greater in Group C compared to Group B. Alanine transaminase （ALT） and aspartate transaminase （AST） release into perfusate were 2-3-fold higher in Group B compared to Group C. No significant differences were found in ALT and AST release between Group C and Group A. Livers in Group CC compared to Group BB exhibited significantly lower portal resistance, greater oxygen consumption and bromosulfophthalein excretion into bile and lower lactate dehydrogenase （LDH） release into perfusate. Histological evaluation of tissue sections in Group BB showed parenchymal dystrophy of hepatocytes, while dystrophy ofhepatocytes was absent in Group CC. Livers preserved at 13 ℃ for 24 h exhibited severe ischemic injury Conclusion： These results suggest that the conventional way of liver preservation is not suitable at least for rat livers and that slow cooling of HTK solution during the initial phase of cold storage can improve liver viability during reperfusion.     

Plants have a chance: outdoor educational programmes alter students' knowledge and attitudes towards plants

Outdoor educational programmes are generally believed to be a suitable alternative to conventional biology settings that improve participants' environmental attitudes and knowledge. Here we examine whether outdoor educational programmes focused solely on practical work with plants influence participants' knowledge of and attitudes towards plants. It was found that mean scores of participants' attitudes towards and knowledge of plants significantly increased after the outdoor programme. These effects remained significant even after three months' post‐testing. No similar patterns were found in the control group. Interestingly, the proportion of participants who liked biology as a school subject also significantly increased after the outdoor programme in the experimental group. Females showed better knowledge of plants than males, but attitudes towards plants were similar between genders. Having a garden at home was not associated with better knowledge or attitudes towards plants. Our results reveal that outdoor programmes significantly relieve ‘plant blindness’ and make biology more attractive to pupils.     

Good and evil at school: Bullying and moral evaluation in early adolescence

We investigated how adolescents (sixth-graders, N = 357) morally evaluated hypothetical bullying and defending protagonists and whether these evaluations related to behavior in bullying as nominated by peers. Exploratory factor analysis (EFA) resulted in four factors for the evaluation of the hypothetical bullies: Evil soul, Contempt, Cowardice, and Deviance, and five factors for the evaluation of the hypothetical defender: General admiration, Courage, Cool, Empathic care, and Fair justice. Corresponding scales were constructed. The findings showed that bullying positively correlated with evaluating the hypothetical bullies using Cowardice while victimization positively correlated with evaluating the hypothetical defender in terms of General admiration, Empathic care, and Fair justice. MANOVA for each of the two sets of the evaluative scales indicated that behavioral status (bully, victim, defender, or uninvolved) had a significant effect on the moral evaluation of hypothetical bullies, and no significant effect on the moral evaluation of the hypothetical defender.     

Validity of E-Advice: The Evaluation of an Internet-Based System for Career Planning

The paper provides data on the evaluation of an Internet-based system for self-directed career planning that has been developed in Croatia. Rich in occupational information and career-management advice, this application also contains an interactive questionnaire tapping the client's personal skills and interests. Based on the client's answers, the computer proposes an e-advice– a limited set of occupations that match the users' individual characteristics. The evaluation utilized data gathered from a self-selected sample of users (N = 2,064) and two smaller student samples. Apart from the users' satisfaction, the analyses explored various aspects of e-advice validity: factor structure of users' self-assessments and expert occupational ratings, differences in e-advice given to different groups of users, congruence with the classifications based on Holland's Self-Directed Search, and congruence with the advice given by expert human counsellors. The analyses supported the validity of e-advice. This revised version was published online in August 2006 with corrections to the Cover Date.     

Learning Environment in Light of Positional,Institutional, and Cultural Interpretations: An Empirically-Based Conceptual Analysis

This study explores the possibility that the concept of learning environment (LE) is understood and interpreted differently by various users, depending on their relative positions in the educational system, institutional affiliation, and cultural heritage. The study employs a qualitative approach and is based on 14 semistructured separate interviews with professionals in the field of education. The participants in the study have been chosen from 3 different levels in the educational system (assistants, kindergarten and school teachers, and principals/county government representatives) and across different institutions (kindergartens and schools). The data reveal a clear pattern in which the conceptualization of LE is influenced by the relative positions of the actors, established practices and norms inside the specific system, and the cultural heritage of the given context. The tendency of various stakeholders to understand and interpret LE differently has direct implications for development and implementation of future educational policies. The study emphasizes that the awareness of these effects is important for (a) successful communication between educational professionals operating in different positions in the system, and (b) the academic community, which tends to shape the manner in which the theoretical concepts are defined.     

The challenges of setting up the evaluation of extension systems by using a systems approach: the case of Greece,Italy and Slovenia

Purpose: Considering current debates on ecosystem services’ effectiveness and the AIS/AKIS functioning, in this study we suggest a new, systemic way to evaluate extension systems (ESs). Using this model, we compared the effectiveness of ESs in three countries with essential differences but also characteristic similarities in their agricultural sectors: Greece, Italy and Slovenia.

Design/methodology/approach: Initially, we defined ‘extension system’ as a wide range of actors integrating resources with the aim of co-producing value (not for but with) farmers. To capture the value flow within this constellation of actors we distinguished between the notion of ‘value in production’ – i.e. the value embodied in service offerings – and the value emanating when service content is used in real settings or ‘value in use.’

Findings: Our approach revealed that, despite their structural and organizational differences, the ES in the three countries share common problems arising from a limited focus on the issue of value in use.

Practical implications: The application of a systemic approach – seeing farmers as co-creators and not as end-users of extension services – in the evaluation of ESs contributes to better understand the complexity of value flow within the system and can strengthen extension systems’ effectiveness.

Theoretical implications: The present study, by reconsidering traditional evaluation approaches and by focusing on value co-production, offers an alternative value-centric framework for the conceptualization of extension services and points out to the need for refining the evaluation criteria of ESs.

Originality/value: Our work, by emphasizing the reciprocal creation of value within ESs, and by adding the concept of value in use, offers a new systems approach worth considering when evaluating ESs within different organizational and sociocultural contexts.
