Conceptualising success and failure for social movements

The paper discusses some of the most significant conceptions of success and failure present in the social movement literature, and highlights the gaps present in these theories. Through a seven-pronged critique, the paper stresses that the prevalent conceptions of movement success or failure are inherently unable to grasp the overall consequences and essence of a social struggle. Moreover, it is argued here that the problem lies not just in these conceptions, but also the concept of success or failure, because in its application to an entity as dynamic and complex as a struggle, it is unable to transcend beyond its black-and-white confines. It trivialises the concept of failure, which is an opportunity for learning from experiences, a chance for error correction and a prospect to rise higher than ever before

Timing and correction of stepping movements with a virtual reality avatar

Research into the ability to coordinate one’s movements with external cues has focussed on the use of simple rhythmic, auditory and visual stimuli, or interpersonal coordination with another person. Coordinating movements with a virtual avatar has not been explored, in the context of responses to temporal cues. To determine whether cueing of movements using a virtual avatar is effective, people’s ability to accurately coordinate with the stimuli needs to be investigated. Here we focus on temporal cues, as we know from timing studies that visual cues can be difficult to follow in the timing context. Real stepping movements were mapped onto an avatar using motion capture data. Healthy participants were then motion captured whilst stepping in time with the avatar’s movements, as viewed through a virtual reality headset. The timing of one of the avatar step cycles was accelerated or decelerated by 15% to create a temporal perturbation, for which participants would need to correct to, in order to remain in time. Step onset times of participants relative to the corresponding step-onsets of the avatar were used to measure the timing errors (asynchronies) between them. Participants completed either a visual-only condition, or auditory-visual with footstep sounds included, at two stepping tempo conditions (Fast: 400ms interval, Slow: 800ms interval). Participants’ asynchronies exhibited slow drift in the Visual-Only condition, but became stable in the Auditory-Visual condition. Moreover, we observed a clear corrective response to the phase perturbation in both the fast and slow tempo auditory-visual conditions. We conclude that an avatar’s movements can be used to influence a person’s own motion, but should include relevant auditory cues congruent with the movement to ensure a suitable level of entrainment is achieved. This approach has applications in physiotherapy, where virtual avatars present an opportunity to provide the guidance to assist patients in adhering to prescribed exercises

Measuring miniature eye movements by means of a SQUID magnetometer

A new technique to measure small eye movements is reported. The precise recording of human eye movements is necessary for research on visual fatigue induced by visual display units.1 So far all methods used have disadvantages: especially those which are sensitive or are rather painful.2,3 Our method is based on a transformation of mechanical vibrations into magnetic flux variations. In order to do this a small magnet is embedded in a close-fitting soft contact lens. The magnetic flux variations caused by eyeball movements during fixation are measured by means of a SQUID magnetometer. The recordings show the typical fixation pattern of a human eye. This pattern is composed of three kinds of movements: saccades, drift and microtremor. The last-mentioned type of movements are displacements in the order of 2 μm. It is possible to distinguish between movements which are perpendicular to each other

Refugee movements and aid responsiveness

This article analyses the impact of refugee migration movements on the long-term and short-term aid allocation decisions of bilateral donors. We distinguish between different types of forced migrants: internally displaced persons (IDPs) that stay in their country of origin, cross-border refugees that flee to neighboring countries, and asylum seekers in Western donor states. For the period 1992 to 2003, empirical evidence on 18 donor and 148 recipient countries suggests that short-term emergency aid is given to all types of refugee situations, but is predominantly directed towards the countries of origin. For the allocation of long-term development aid, donor states focus even more on the sending-countries of forced migrants; in general, they increase aid volumes only for the home countries of refugees, not for the hosting countries. This preference for the countries of origin is even stronger when these are sendingcountries of asylum seekers to the Western aid-giving states.Bilateral aid allocation, refugee movements

International Investment Movements

In recent years foreign investment has become an important feature of the development of world economy. The aim of this study is to determine the main factors that stimulate international investment flows. For this purpose the theory of international investment will be reviewed in the first section of the work. The classification of the macro- and microeconomic factors influencing international investment movements will be represented. In the second section of the study, the regression analysis (times series and pooled regressions) is used to show that there is a relationship between imports (X) and inward foreign investment (Y); exports (X) and outward foreign investment (Y); inward foreign direct investment (X) and employment (Y); and inward foreign direct investment (X) and exports (Y).

Demographics of cattle movements in the United Kingdom

Background: The United Kingdom (UK) government has been recording the births, deaths, and movements of cattle for the last decade. Despite reservations about the accuracy of these data, they represent a large and valuable body of information about the demographics of the UK cattle herd and its contact structure. In this article, a range of demographic data about UK cattle, and particularly their movements, are presented, as well as yearly trends in the patterns of movements. Results: A clear seasonal pattern is evident in the number of movements of cattle, as are the reductions in movement volume due to foot and mouth disease outbreaks in 2001 and 2007. The distribution of ages of cattle at their time of death is multimodal, and the impact of the over thirty months rule is marked. Most movements occur between agricultural holdings, markets, and slaughterhouses, and there is a non-random pattern to the types of holdings movements occur between. Most animals move only a short distance and a few times in their life. Most movements between any given pair of holdings only occurred once in the last 10 years, but about a third occurred between 2 and 10 times in that period. There is no clear trend to movement patterns in the UK since 2002. Conclusions: Despite a substantial number of regulatory interventions during the last decade, movement patterns show no clear trend since 2002. The observed patterns in the repeatability of movements, the types of holdings involved in movements, the distances and frequencies of cattle movements, and the batch sizes involved give an insight into the structure of the UK cattle industry, and could act as the basis for a predictive model of livestock movements in the UK

Scaling of Horizontal and Vertical Fixational Eye Movements

Eye movements during fixation of a stationary target prevent the adaptation of the photoreceptors to continuous illumination and inhibit fading of the image. These random, involuntary, small, movements are restricted at long time scales so as to keep the target at the center of the field of view. Here we use the Detrended Fluctuation Analysis (DFA) in order to study the properties of fixational eye movements at different time scales. Results show different scaling behavior between horizontal and vertical movements. When the small ballistics movements, i.e. micro-saccades, are removed, the scaling exponents in both directions become similar. Our findings suggest that micro-saccades enhance the persistence at short time scales mostly in the horizontal component and much less in the vertical component. This difference may be due to the need of continuously moving the eyes in the horizontal plane, in order to match the stereoscopic image for different viewing distance.Comment: 5 pages, 4 figure

Universities, social movements and market forces

Universities have changed drastically over the past few decades. To understand and articulate what has happened, I make a stab at answering, however sketchily, the following questions: What forces have shaped universities over recent decades? What as been the impact of social movements such as socialism, feminism, africanism on the process of the production of knowledge? Why has it been deemed necessary, not only to demand inclusion of the excluded in the domain of higher knowledge, but to challenge the existing canon and to struggle for radically new approaches to curricula? What has been achieved by history from below, gender studies, african studies, postcolonial studies? What has happened to all the passionate debates between contending paradigms? Are market forces marginalising all else? Is it desirable and/or possible to resist? How is the project of academic transformation in South Africa unfolding within this global field of forces
