Job description

This
multi-technique PhD project is designed to validate if mineral
inclusions in diamond record the time of diamond growth. Newly developed
ultra-sensitive isotopic analysis applied to diamond, single silicate
and sulphide inclusions will determine if there is Sr-Nd-Pb isotope
equilibrium between the host diamond and minerals in individual growth
zones. Diamonds with multiple inclusions from four Botswana mines will
be studied (Orapa-Letlhakane-Damtshaa-Jwaneng). The methodology involves
spectroscopic characterization of growth zones before dating and stable
isotope analysis (C-O-N). Three-dimensional cathodoluminescence imaging
and electron backscatter diffraction techniques will establish if
specific mineral inclusions are syn- or proto-genetic with the host
diamond. The host diamond and multiple inclusions will then be analysed
isotopically (Sr-Nd-Pb). The aim is to establish if protogenetic
inclusions have reached isotopic equilibrium due to rapid elemental
diffusion in the mantle during diamond precipitation from a
volatile-rich medium. Re-Os dating of sulphides in the same growth zones
will validate the age data from both syn- and protogenetic silicate
minerals. The ultimate goal is to determine the number and timing of
different diamond forming events beneath individual mines and hence the
length- and time-scale over which diamond forming events operate and the
time taken to form individual diamonds.

Requirements

• A completed MSc degree in the field of mineralogy-petrology-geochemistry, or similar relevant field;
• experience in the interpretation of complex mineralogy or geochemistry datasets;
• proven strong mineralogy or geochemistry analytical skills;
• excellent research and writing skills, proven by past accomplishments;
• good command of the English language;
• good communication skills and ability to work in an interdisciplinary team.

Job description

Tilburg Law SchoolTilburg University is a modern and specialized university. With a broad variety of international programs and innovating research (Law, Public Administration), Tilburg Law School stands for high quality. Research at the Tilburg Law School is conducted in an organization that fosters diversity. The Tilburg Graduate Law School is responsible for the training and guidance of its Research Master students and of the Faculty's PhD researchers. With its open and inspiring atmosphere, this Faculty is a congenial working environment.
The position
At Tilburg Law School we have a vacancy for a highly talented post-doctoral researcher who will be one of the main researchers in the project ‘Smart Transformations in City-regional Law and Governance’, which is funded by the Netherlands Organization for Scientific Research and Province North-Brabant. The project focuses on analyzing and developing innovative and adaptive co-operation across several boarders, in order to address local and regional authorities’ increasing loss of the possibilities for autonomous policy-making. In essence, what is needed for effective governing, is hybrid governance across (sub-)national territorial boarders, across sectors and across the public-private divide. In different sectors new ways of governing, such as tripartite co-operations and a growing use of ‘alternative’ governance instruments, have been witnessed. Their effectiveness may very well depend on the context of the sector with its specific regulations. Intriguing question then is whether a governance arrangement that is solid in one context could also prove to be beneficial in another context. Mutual learning is vital for innovative urban and regional governance and regional law. Hybrid governance is challenging, and it has, potentially, at least one downside: the difficult safeguarding of its democratic legitimacy. Traditional direct legitimization has eroded, partly because it only provides direct legitimacy at one level whereas governance is nowadays multi-level. Besides, elected councils only represent citizens in places where the latter live and vote, while citizens are bound to have interests in places where they do not live (and vote) but work, recreate, or identify without the possibility of securing representation. In this interdisciplinary research project, the postdoctoral researchers shall analyse both the legal and governance implications of hybrid instruments, and answer the two focal research questions:
(1) How, and to what extent, can policy and lawmakers learn from experiences with hybrid governance in different contexts;
(2) How can democratic legitimacy be safeguarded in a context of hybrid governance?
The researcher will study and compare international cases, in close co-operation with other researchers and practitioners in the city-regions concerned.
The research context
In this position the researcher will closely co-operate with other postdoc researchers and the project leaders, dr. L. Schaap & mr. dr. S.H. Ranchordás. The positions are functionally integrated in Tireg, the Brabant Center for Transformations in Regional Law and Governance (which is in the process of being established). You take an active role in Tireg contributing to its fundamental research as well as its activities aimed at learning of practitioners, and will assist in organizing conferences and workshops. In addition, you will contribute to the visibility and reputation of Tireg in the Netherlands, at the European level and internationally. Teaching may also be part of the activities.

Requirements

In the light of the above, we are looking for a talented researcher who has completed a Ph.D. in Public law or in Public Administration/Political Science. Applicants should be acquainted with or be able to demonstrate that they are interested in regional issues and working with practitioners. Candidates are expected to combine good research skills with excellent networking and communicative skills, an entrepreneurial mindset, creativity in theoretical as well as methodological matters, and the ability to help build Tireg.
In addition, candidates should have demonstrable experience with both individual and team-work research, preferably in an international environment, and have an excellent command of English, both written and spoken. Candidates should also master Dutch or be willing to learn Dutch rapidly, in order to be able to deal with Dutch-language materials and with Dutch speakers in due time.  A good command of German (at least speaking and reading skills) is also highly recommended.
