Change is a constant in our profession, and we are familiar with this on a daily basis, as we constantly change how we practise. But consider how the way we learn and the very structure of our profession has changed in recent years. If I think back, I attended a traditional dental school and had, in my view, an excellent undergraduate education. Compare that top-down approach to the approach today, with its self-directed learning and student-led clinics – to give a couple of examples of a bottom-up model of providing effective dental education. The net result of this, in my view, is that today’s graduates are a little different in many respects, both when they graduate and in their long-term career ambitions.

With chapter 6 having described the way norms for mental-state ascriptions operate in a top-down manner in discourse domains, chapter 7 explores how individual narratives can in turn have a bottom-up impact on the ascriptive norms circulating within particular domains. To this end, the chapter discusses how Thalia Field’s 2010 experimental narrative Bird Lovers, Backyard employs a strategic oscillation between two nomenclatures that can be used to profile nonhuman as well as human behaviors: (1) the register of action, which characterizes behavior in terms of motivations, goals, and projects; and (2) the register of events, which characterizes behavior in terms of caused movements that have duration in time and direction in space. In braiding together these two registers, Field’s text suggests not only how discourse practices can be repatterned, but also how such repatterning enables broader paradigm shifts—in this case shifts in ways of understanding cross-species encounters and entanglements.

The way “the local” had been interpreted led to contrasting top-down or bottom-up understandings of local infrastructures for peace. This chapter presents a reinterpretation of the relevance of infrastructures for peace from a practitioner’s perspective, considering past experiences and current theoretical debates. It argues for an appreciation of the complex, interlinked nature of global, national, and local conflicts and the necessity of flexible yet sustained and productive dialogue platforms at the points of frictional interactions at and between all these levels. The capacity to initiate and support such dialogue platforms where, crucially, local agency is respected is at the core of the approach that became known as “infrastructures for peace.”


Huey Percy Newton (b. 1942–d. 1989) is a singular figure in African American history. Born in Monroe, Louisiana to Armelia Johnson and Walter Newton, he joined the Great Migration as a child when his family relocated to Oakland, California. He graduated from Oakland Technical High School in 1959, but forever claimed that school failed him, notably in the fact that he graduated without learning to read. Alongside self-directed learning, he then studied at Merritt College in Oakland, one of the city’s hotbeds of political discussion and activism. After joining, and becoming disillusioned by, a sequence of campus organizations, in October 1966 he formed the Black Panther Party (BPP) with his friend and fellow student Bobby Seale, who credits Newton as the principal architect of the BPP’s political philosophy and the driving force behind its early activism. The BPP initially focused on protesting police brutality in Oakland, most importantly through a sequence of patrols of police officers, which involved armed Panthers observing police activities in Oakland, informing local citizens of their legal rights during any arrest procedure and ensuring that the police conducted their duties lawfully and respectfully; and the May 1967 protest at the California State Capitol, one of the central events of the 1960s (although Newton was absent from the latter due to probation restrictions). On 28 October 1967 he was charged with the murder of Oakland police officer John Frey. The subsequent trial transformed the BPP and Newton into international phenomena. Despite a fervent “Free Huey” campaign and a bravura defense from his attorney, Newton was convicted of voluntary manslaughter. He served two years in prison, being released after his appeal revealed that the presiding judge of his original trial twice incorrectly instructed the jury and allowed disputed evidence to be presented to the jury. Two further retrials led to deadlocked juries. Returning in August 1970 to a transformed BPP, Newton struggled to cope with the fame and expectations placed upon him. Just as important was an extensive FBI campaign of disinformation, surveillance, infiltration, and occasional violence. Newton’s long-term use of cocaine did little to help. In 1974 he fled the United States for Cuba, fearing prosecution for the murder of a teenager, Kathleen Smith. He returned in 1977 to face the charges, which were eventually dropped. Following the collapse of the BPP amid accusations of financial impropriety, Newton essentially disappeared from public life. He was shot and killed in West Oakland by Tyrone Robinson, a local gang member, following an altercation over a drug deal.

This paper introduces an approach to compare simulation runs from multiple System Dynamics simulation models. Three dynamic hypotheses regarding the uncertain evolutions of long-term copper availability are introduced and used to illustrate the new approach. They correspond to three different perspectives on the copper system (global top-down, global bottom-up, and regional top-down). Although each of these models allows to generate a wealth of behavioural patterns, the focus in this paper is on the differences in trajectories caused by different models for identical values of shared parameters and identical settings of other assumptions, not on differences in behavioural patterns caused by each of the models. Hence, differences in trajectories between the three models are identified, quantified, and classified based on a quantified measure of difference. For these models, small differences between the trajectories are only found in stable runs, while the alternative perspectives are largely responsible for medium to large differences. Hence, it is concluded that multiple dynamic hypotheses may have to be modelled when dealing with uncertain issues.

Background: The medical college library plays an important role in enhancing theacademic achievements of medical students. In order to improve the quality oflibrary services this study provided an assessment of the impact of the libraryservices on undergraduate medical student learning behavior. Materials and methods: This was a cross-sectional descriptive type of study. Thestudy used a self-designed questionnaire. The study sample was 200 undergraduatemedical students. The questionnaire was administered to them at the end of theirlecture class. Results: The primary reason for going to the library was self study (68%) refer text(37%) and group study (36%). Only 38.55% of the respondents visited the library ona daily basis, 50.5% students visit library when necessary and 10.5% student uselibrary 2-3 times a week. All students (100%) are aware about availability of textbooks in the library. 60.5% students know that journals are available in their library,52% know about dictionaries, 56.55% know of having internet, 62.5% students knowthat computers are available in library. 46.5% students said that their internet ofinstitutional library is somewhat helpful. Noise (67.5%), insufficient space (66%),lack of interent access (46%) and lack of computers(44.5%) might have negativeinfluence on the students in library visit. Conclusion :The study suggested that fulfillment of more needs to be done topromote self directed learning. The usage of library, its resources and services needto be increased.

In theories of auditory scene analysis and melodic implication/realization, melodic expectation results from an interaction between top-down processes (assumed to be learned and schema-based) and bottom-up processes (assumed innate, based on Gestalt principles). If principles of melodic expectation are partly acquired, it should be possible to manipulate them – to condition listeners' expectations. In this study, the resistance of three bottom-up expectation principles to learning was tested experimentally. In Experiment 1, expectations for stepwise motion (pitch proximity) were manipulated by conditioning listeners to large melodic leaps; preference for small intervals was reduced after a brief exposure. In Experiment 2, expectations for leaps to rise and steps to fall (step declination) were manipulated by exposing listeners to melodies comprising rising steps and falling leaps; this reduced preferences for descending seconds and thirds. Experiment 3 did not find and hence failed to alter the expectation for small intervals to be followed by an interval in the same direction (step inertia). The results support the theory that bottom-up principles of melodic perception are partly learned from exposure to pitch patterns in music. The long-term learning process could be reinforced by exposure to speech based on similar organization principles.

Welcome to this new SiSAL column, which will examine a long-term project conducted at one institution in depth over several issues. The focus of this column will be the curriculum design project currently being undertaken at the Self-Access Learning Centre (SALC) at Kanda University of International Studies (KUIS) in Chiba, Japan. In my role as Academic Coordinator of the SALC from 2011-2013, I was in charge of leading this project in its initial stages, before I moved institution. As editor, it is from this perspective, as someone familiar but no longer directly involved in the project, that I hope to collate and introduce a number of columns from the learning advisors and teachers who are conducting the research and designing the new self-directed learning curriculum. In this first installment, a revision of an earlier article which first appeared in the IATEFL Learner Autonomy SIG newsletter, Independence, (Thornton, 2012) I present the background to the project, the framework used to guide it and the results of the first stage, the environment analysis.

ABSTRACT Since radiocarbon accelerator mass spectrometry (14C AMS) is considered a high-precision technique, reassessment of the measurement uncertainty has been a topic of interest. Scientists from analytical and metrological fields have developed the top-down and bottom-up measurement of uncertainty approaches. The 14C quoted error should approximate the uncertainty of long-term repetitions of the top-down approach in order to be realistic. The novelty of this paper is that the uncertainty of both approaches were approximated to each other. Furthermore, we apportioned the graphitization, instrumentation, and bias components in order to additively expand the quoted error. Our results are comparable to error multipliers and to long-term repeatability studies reported by other laboratories. Our laboratory was established in late 2012 with N2 as stripper gas and 7 years later, we changed to helium stripper. Thus, we were able to compare both gases, and demonstrate that helium is a better stripper gas. In absolute F14C units, the ranges of graphitization+bias combined uncertainties were (0.7 to 4.1) × 10–3 for N2 and (0.7–3.0) × 10–3 for He depending on the standard 14C content. The error multiplier for He defined as the expanded uncertainty over quoted error, in average, was 1.7; while without the bias, the multiplier was 1.3.

The development of scenarios for quantitative or qualitative analysis is a key element of the assessment of the safety of geological disposal systems. As an outcome of an international workshop attended by European and the Japanese implementers, a number of features common to current methodologies could be identified, as well as trends in their evolution over time. In the late nineties, scenario development was often described as a bottom-up process, whereby scenarios were said to be developed in essence from FEP databases. Nowadays, it is recognised that, in practice, the approaches actually adopted are better described as top-down or “hybrid”, taking as their starting point an integrated (top-down) understanding of the system under consideration including uncertainties in initial state, sometimes assisted by the development of “storyboards”. A bottom-up element remains (hence the term “hybrid”) to the extent that FEP databases or FEP catalogues (including interactions) are still used, but the focus is generally on completeness checking, which occurs parallel to the main assessment process. Recent advances focus on the consistent treatment of uncertainties throughout the safety assessment and on the integration of operational safety and long term safety.
