The Effects of an Instructor\u27s Use of Hesitation Forms on Student Ratings of Quality, Recommendations to Hire, and Lecture Listening

This study examined the impact of instructor use of hesitation forms ( uh, ah, um, and well ) in an initial encounter with the students on three measures of teaching effectiveness: students ratings of teacher quality, student recommendations to hire, and lecture listening. The instruction of any amount of hesitant speech significantly lowered instructor effectiveness as measured by each dependent variable. Generally, the use of higher frequencies of hesitation forms was more damaging than the use of lower frequencies. The findings of this study suggest that the use of other forms of powerless language may also detract from the teacher effectiveness

Fortifying or fragmenting the state? The political economy of the drug trade in Shan State, Myanmar, 1988-2012

Over the past twenty-five years, the government of Myanmar (Burma) has consolidated control over large parts of Shan State, neutralizing much of the threat posed by armed groups and strengthening its hold over revenue extraction. During this period Myanmar has retained its position as the world's second largest producer of illicit opium, much of which is converted into heroin within the country's borders. This article explores the relationship between state-building processes and the illicit opium/heroin economy in Shan State since 1988. The author has four aims. First, to reassess the theoretical assumptions that equate illicit economies with state fragility and demonstrate instead why illicit drug economies can become embedded in processes of conflict reduction and state consolidation. Second, to explain why establishing control over Shan State has become so important to the Myanmar government's state-building ambitions. Third, to analyze how the state's engagement with the drug trade has become a vital part of its attempts to consolidate control, in terms of financing military expansion and brokering deals with strongmen who are able to govern local populations. Finally, to assess how these strategies embody a form of “negotiated statehood” in which the state's growing control has been defined by attempts to manage, rather than monopolize, the means of coercion and extraction

Economic Analysis of Knowledge: The History of Thought and the Central Themes

Following the development of knowledge economies, there has been a rapid expansion of economic analysis of knowledge, both in the context of technological knowledge in particular and the decision theory in general. This paper surveys this literature by identifying the main themes and contributions and outlines the future prospects of the discipline. The wide scope of knowledge related questions in terms of applicability and alternative approaches has led to the fragmentation of research. Nevertheless, one can identify a continuing tradition which analyses various aspects of the generation, dissemination and use of knowledge in the economy

In-situ estimation of ice crystal properties at the South Pole using LED calibration data from the IceCube Neutrino Observatory

The IceCube Neutrino Observatory instruments about 1 km3 of deep, glacial ice at the geographic South Pole using 5160 photomultipliers to detect Cherenkov light emitted by charged relativistic particles. A unexpected light propagation effect observed by the experiment is an anisotropic attenuation, which is aligned with the local flow direction of the ice. Birefringent light propagation has been examined as a possible explanation for this effect. The predictions of a first-principles birefringence model developed for this purpose, in particular curved light trajectories resulting from asymmetric diffusion, provide a qualitatively good match to the main features of the data. This in turn allows us to deduce ice crystal properties. Since the wavelength of the detected light is short compared to the crystal size, these crystal properties do not only include the crystal orientation fabric, but also the average crystal size and shape, as a function of depth. By adding small empirical corrections to this first-principles model, a quantitatively accurate description of the optical properties of the IceCube glacial ice is obtained. In this paper, we present the experimental signature of ice optical anisotropy observed in IceCube LED calibration data, the theory and parametrization of the birefringence effect, the fitting procedures of these parameterizations to experimental data as well as the inferred crystal properties.</p

Sketching women in court: The visual construction of co-accused women in court drawings

This paper explores the visual construction and representation of co-accused women offenders in court drawings. It utilises three case studies of female co-defendants who appeared in the England and Wales court system between 2003 and 2013. In doing so this paper falls into three parts. The first part considers the emergence of the sub-discipline, visual criminology and examines what is known about the visual representation of female offenders. The second part presents the findings of an empirical investigation, which involved engaging in a critical, reflexive visual analysis of a selection of court drawings of three female co-offenders. The third part discusses the ways in which the court artists' interpretation, the conventions of court sketching, and motifs of female offenders as secondary actors, drew on existing myths and prejudices by representing the women as listening, remorseless ‘others’

h or the lower branch. It probably doesn&apos;t matter which method you use. The operation of adding the previous accumulated error metrics to the new branch metrics, comparing the results, and selecting the smaller (smallest) accumulated error metric to be retained for the next time instant is called the add-compare-select operation. The figure below shows the results of processing t = 3: Note that the third channel symbol pair we received had a one-symbol error. The smallest accumulated error metric is a one, and there are two of these. Let&apos;s see what happens now at t = 4. The processing is the same as it was for t = 3. The results are shown in the figure: Notice that at t = 4, the path through the trellis of the actual transmitted message, shown in bold, is again associated with the smallest accumulated error metric. Let&apos;s look at t = 5: At t = 1, we received 00 2. The only possible channel symbol pairs we could have received are 00 2 and 11 2 . The Hamming distance between 00 2 and 0
