Introduction research focus on agricultural wage work topic: analysis of requirements concerning agricultural workers from the perspective of agricultural managers (skilled employees and managers) began writing in September 2009 supervisor: Prof. Poehls (University of Applied Sciences Neubrandenburg) and Prof. Bokelmann (Humboldt University) thesis connected to research of Prof. Poehls concerning evaluation of curricula of educational programs in agriculture Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin

research focus on agricultural wage work

topic: analysis of requirements concerning agricultural workers from the perspective of agricultural managers (skilled employees and managers)

began writing in September 2009

supervisor: Prof. Poehls (University of Applied Sciences Neubrandenburg) and Prof. Bokelmann (Humboldt University)

thesis connected to research of Prof. Poehls concerning evaluation of curricula of educational programs in agriculture

Aim Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin analysis of significance of different attributes regarding agricultural skilled employee and agricultural managers for example: How important is work experience and what level is the best? more attributes: academic degree, vocational education, different levels of soft skills etc. view of employers in agricultural production comparison with views of experts from educational institutions furthermore: requirements concerning managers from the focus of entrepreneurship

analysis of significance of different attributes regarding agricultural skilled employee and agricultural managers

for example: How important is work experience and what level is the best?

more attributes: academic degree, vocational education, different levels of soft skills etc.

view of employers in agricultural production

comparison with views of experts from educational institutions

furthermore: requirements concerning managers from the focus of entrepreneurship

Method Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin quantitative analysis choice-based conjoint analysis (=discrete choice) analysis of contribution of different components to overall utility resolving part worth utilities reflect relevancies of different attributes paper-pencil-interview: interviewees will be asked to choose between two virtual employees (several times)

quantitative analysis

choice-based conjoint analysis (=discrete choice)

analysis of contribution of different components to overall utility

resolving part worth utilities reflect relevancies of different attributes

paper-pencil-interview: interviewees will be asked to choose between two virtual employees (several times)

Method (2) Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin theoretical background: random utility theory modelling of choice decision with multinominal logit model estimation of utility with maximum likelihood estimation (OLS not possible)

theoretical background: random utility theory

modelling of choice decision with multinominal logit model

estimation of utility with maximum likelihood estimation (OLS not possible)

Significance Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin situation: rising requirements regarding agricultural labour (professionalisation + specialisation) improvement of educational quality of labour force necessary: fitting educational programs education = crucial future and cost factor for farms results may influence educational institutions (vocational school, universities etc.)

situation:

rising requirements regarding agricultural labour (professionalisation + specialisation)

improvement of educational quality of labour force

necessary: fitting educational programs

education = crucial future and cost factor for farms

results may influence educational institutions (vocational school, universities etc.)

Status Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin comprehensive literature review of similar studies obtaining relevant textbooks regarding method evaluation of software to use (Excel, SPSS, SAS, Sawtooth) different software for different purposes Excel for maximum likelihood estimation (Solver) SPSS or SAS for construction of an orthogonal design of choice sets SAS for the construction of an efficient experimental design (SAS/QS) Sawtooth as “Swiss Army knife”, but somewhat a black box

Problems Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin How to sum up similar studies from the past to derive the time development of requirements from the results? Studies too heterogeneous and rare to use meta- or best-evidence-analysis narrative solution possible, but somewhat “unscientific” more problems likely to follow
