A Care Ethical Perspective on the Leadership of Gurus

Aanleiding voor dit onderzoek waren het onethisch leiderschap van gurus en het weinig onderzochte veld van zorgethiek en leiderschap. De bestaande literatuur omtrent leiderschap en zorgethiek is hiervoor vergeleken met het werk van Tronto (1993) en Walker (2007) over macht en ongelijkheid en de analyses van Jensen (2019) en Van der Braak (2006) van leiderschapsethiek van gurus. De analyse hield codering en de creatie van vergelijkingstabellen in. De belangrijkste uitkomst is de overlap tussen ‘zorgzaam leiderschap’ (leiderschap op basis van zorgethiek) en leiderschap van gurus dat ethisch wordt genoemd door Jensen (2019) en Van der Braak (2006), hier genoemd: ‘zorgzaam guru leiderschap’. Hoewel hierin macht, ongelijkheid en het delen van macht een positieve rol spelen, worden op basis van Tronto (2013) en Walker (2007) kritische kanttekeningen geplaatst wat betreft de haalbaarheid. Toekomstig onderzoek wordt aangeraden o.a. om het perspectief van de guru, dat in dit onderzoek ondergepresenteerd is, meer te belichten

A queueing model of a foreground-background time-sharing system with general service times and constant swap times

A time-sharing system is modelled by a foreground-background queue with Poisson arrivals and independent and identically distributed service times with a general distribution function H. Waiting times in system are analysed for jobs, which arrive in a stationary process, and the Laplace-Stieltjes transforms of their distribution functions are derived. This is done for a non-preemptive and a preemptive-resume priority rule with several policies to deal with constant swap times, which have to be attached each time the processor attends another job. Some remarks about extensions to models with K > 2 queues are made

Removal of nitrogen leaching from vegetable crops in constructed wetlands

Vegetable growing leads to high nitrogen emissions. In the Netherlands, nitrogen emissions can hardly be reduced by reducing fertilization without risks for yield and quality loss. An alternative measure to reduce emissions is to collect nitrate-rich drain water and remove nitrate from the drain water in constructed wetlands. This was tested in three different types of constructed wetlands at an experimental farm in the SE of the Netherlands: (1) a surface flow system (SF) planted with Common reed, (2) a horizontal subsurface flow system with Common reed (SSF-reed) and (3) a horizontal subsurface flow system filled with straw (SSF-straw). The water discharge into the wetlands is adjusted to the nitrate removal capacity of the wetlands. In- and outlet concentrations of nitrogen and other nutrients were measured every two weeks since December 2005. Collected water from pipe drains contained on average 30 mg N L-1. The mean N removal was 58% in SF (1655 kg N ha-1 year-1), 25% in SSF-reed (1447 kg ha-1 year-1) and 63% in SSF-straw (3622 kg N ha-1 year-1). SF and SSF-straw are functioning well. In SSF-reed, the amount of carbon seems to be insufficient to sustain nitrogen reduction. Disadvantage of SSF-straw is the negative removal rate of phosphorus (mean 16 kg ha-1). With a removal rate of about 60% within the system, about 20% of the leached nitrogen from the vegetable fields could be removed: about two-third of the leached water is collected in drains and half of the nitrate-rich drain water is collected for purification. The cost effectiveness (expressed as € per kg N removed) ranged between € 52 and € 104 kg-1 N for SF, between € 29 and 58 kg-1 N for SSF-straw and between € 161 and € 322 kg-1 N for SSF-reed. Cost reduction is possible by combining with other functions as water storage and nature developmen

Structuring for serendipity: family wealth creation, farmer autonomy and the pursuit of security in an uncertain Australian countryside

The social and economic particularities of family farms have captured researchers’ attention for many years; but rural scholarship still lacks a clear, analytical sense of how and why family farms are organised in the ways that they are. This thesis critically examines the internal logics underpinning the socio-economic organisation of Australian farms. It adopts Johnsen’s (2003) conceptualisation of farm enterprises as three-way coalitions between farm businesses, farm households and the respective property holdings. Changes to the Australian agricultural property regime are used as the lens through which to observe how the organisational logics of farm enterprises are recalibrated in response to environmental policy reforms; specifically, the separation of land and water titles. Despite the obvious economic significance of separating land and water titles, the impacts on farm organisation remain under-researched. Hence, this thesis uniquely brings together scholarship on family farming with that of water reforms. A qualitative research method – farm life history – is used to generate narratives of the development of 40 farms in Victoria, Australia. Twenty-one of these are from an irrigation district where land and water titles have been separated, and nineteen from a dry land region unaffected by the reforms. The interpretive chapters comprise an analysis of the ways in which the ownership configurations of farm businesses, land and water assets embody farmers’ aspirations for building wealth and maintaining autonomy. These aspirations are jointly articulated in the concept of ‘structuring for serendipity’, which elevates the notions of risk, uncertainty and security as critical drivers shaping farm-level responses to contemporary conditions. The thesis concludes that the organisational forms observed within the Australian agricultural sector ultimately represent farmers’ pursuit of a sense of security in a constantly changing and uncertain countryside

Who are the job seekers? explaining unemployment among doctoral recipients

Despite increased attention for doctoral education in recent years, one particular phenomenon has received little attention—the unemployment of doctoral candidates following graduation. While the unemployment of doctoral recipients is relatively low in comparison to the general popula-tion, the absence of empirical studies means possible important patterns are being overlooked. Using survey data from four universities in the Netherlands, we investigate unemployment among recent doctoral graduates. By comparing the job seekers to employed doctoral recipients and fo-cusing on both structural and individual level variables, including demographic characteristics, previous research experience, job seeking activities, and differences in the PhD trajectory, we are able to discern a number of shared characteristics among the job seekers. Our findings suggest that unemployment among doctoral candidates is not random or evenly distributed. In contrast to the general population, where socio structural characteristics such as educational level and gender are integral in explaining unemployment, within this level of educational attainment primarily individual level factors are more salient in explaining unemployment among this group of job seekers
