The Rio Grande Cone is a major fanlike depositional feature in the continental slope of the Pelotas Basin, Southern Brazil. Two representative sediment cores collected in the Cone area were retrieved using a piston core device. In this work, the organic matter (OM) in the sediments was characterized for a continental vs. marine origin using chemical proxies to help constrain the origin of gas in hydrates. The main contribution of OM was from marine organic carbon based on the stable carbon isotope (δ13C-org) and total organic carbon/total nitrogen ratio (TOC:TN) analyses. In addition, the 14C data showed important information about the origin of the OM and we suggest some factors that could modify the original organic matter and therefore mask the “real” 14C ages: (1) biological activity that could modify the carbon isotopic composition of bulk terrestrial organic matter values, (2) the existence of younger sediments from mass wasting deposits unconformably overlying older sediments, and (3) the deep-sediment-sourced methane contribution due to the input of “old” (>50 ka) organic compounds from migrating fluids.
Books V-IX of the Confessions trace five crucial years in the life of Augustine, from his debut as a teacher of rhetoric in North Africa to his baptism as a Christian and the renunciation of a worldly career in Milan. This commentary will be invaluable for those wishing to read his story in the original Latin. Through careful glosses and notes, Augustine's Latin is made accessible to students of patristics and of classics. His extensive quotations from Scripture are translated and explained in light of the variant Bible texts and the interpretative assumptions through which he came to understand them. The unfolding of his career is set against the background of political, cultural, and religious change in the fourth century, and the art with which he created a form of narrative without precedent in earlier Latin literature is illustrated in close detail.
Implementing the logical and ontological principles (dualism, mechanicism, reductionism, law of excluded middle, etc.) of modernity has brought forth an unsustainable world. An overcoming of these principles is proposed by mesology (Umweltlehre, fûdoron), centring on the concept of trajection and the existential operator as (als, en tant que).
User-centric development is essential to any product development project, especially in order to keep up with today's ever-changing product cycle.
This paper explores the potential of combining specific aspects of Scrum and Design Thinking to maximise user integration as well as implementing short iterations in hardware development projects, in this use case a three-month development project at a German high-end homeware manufacturer. In addition to observations regarding the application of those approaches this paper will then offer a range of newly developed user-centric methods to efficiently integrate the user's perspective in future development projects, as well as feedback from the product developers at the company and comparisons to current methods.
This use case was furthermore able to illustrate how the employment of such methods made short and sprint-like development cycles within hardware development attainable.
These user-centric methods developed within the use case can be applied to future application- and user- oriented projects in order to speed up the product development process and ensure that the product or service matches the users’ needs and desires.
From campaign rhetoric to tweets, President Trump has positioned himself as “disrupter in chief,” often pointing to administrative action as the avenue by which he is leaving a lasting mark. However, research on the administrative presidency begins with the premise that all presidents face incentives to use administrative tools to gain substantive or political traction. If, as this article suggests, Trump’s institutional standing differs little from his recent predecessors, then how much of the Trump presidency represents a change from past norms and practices? How much represents continuity, or the perennial dynamics of a far-from-omnipotent executive in an ongoing world of “separate institutions sharing powers” (Neustadt 1990, 29)? To answer this, we tracked presidential directives and regulatory policy during Trump’s first year in office. We found evidence of continuity, indicating that in its use of administrative tactics to shape policy, the Trump White House largely falls in line with recent presidencies.
Employment has been cited as one of the most effective protections against recidivism for formerly incarcerated people; however, job seekers with criminal records face barriers to employment after prison. They find themselves in a legal double bind where they are simultaneously compelled to obey the law (by finding “legit” work) but also legally barred from doing so. To navigate this conflictual legal positioning, job seekers with felony records develop strategies of working around the law to find employment. Through thirty qualitative interviews with people with felony records, I examine this alternative form of legal consciousness and detail the ways in which individuals navigate the legal barriers to acquiring “good” work. Ultimately, job seekers’ often extralegal strategies of law abidance blur the line between compliance with and defiance of the law.
