Abstract It is proposed that tire-pavement friction is controlled by thermal rather than by hysteresis and viscoelastic effects. A numerical model of heating effects in sliding is described in which the friction coefficient emerges as a dependent variable. The overall results of the model can be expressed in a closed form using Blok's flash temperature theory. This allows the factors controlling rubber friction to be recognized directly. The model can be applied in quantitative form to metal-polymer-ice contacts. Several examples of correlation are given. The difficulties of characterizing the contact conditions in tire-pavement friction reduce the model to qualitative form. Each of the governing parameters is examined in detail. The attainment of higher friction by small, discrete particles of aluminum filler is discussed.

Issues of power, inequality, and representation in the production of knowledge have a long history in transnational feminist research. And yet the unequal relationship between ethnographers and participants continues to haunt feminist research. Drawing from ethnographic fieldwork with the cooperative Sulá Batsú in Costa Rica between 2015 and 2019, in this essay I argue that centering solidarity and working through discomfort creates relationships that can reinvent and endure the persistent imbalance of power between researcher and participant. I conceptualize a solidarity-based methodology that is uncomfortable, tossing between "us and them," the objective and the subjective, akin to Gloria Anzaldúa’s “nepantla,” a liminal space of both fragmentation and unification, of both anguish and healing: a methodology from the cracks. In this essay, I reflect upon my experiences as a Puerto Rican feminist researcher focusing on Sulá Batsú, specifically on my relationship with the coop’s general coordinator. I conducted ethnographic fieldwork with the coop, including participant observation, in-depth interviews, and textual analysis of their research, briefs, blog posts, presentations, and promotional literature.

Vulnerability Score

The cyclone vulnerability of women is much higher than men due to their poverty, social norms and marginal position in the social structure. Reducing women’s vulnerability is, therefore, imperative to improve the situation. However, the present practices of vulnerability assessment have several limitations. As an alternative, this study proposed and tested a weighted framework to assess the vulnerability in a quantitative form. The proposed framework considers 18 indicators carefully adapted from vulnerability literature. The indicator statuses were defined based on their vulnerability potentials and assigned an integer value. The higher the status value the greater the vulnerability potentials. The indicator’s status values were standardized, and their weights were estimated. The vulnerability scores for every indicator thereafter estimated by multiplying its status value by its weight. Finally, an individual’s vulnerability score was calculated by taking the average vulnerability scores of all the indicators. The framework was tested on 140 randomly selected cyclone-affected women from ten coastal villages of Bangladesh. The proposed scores-based vulnerability expresses the vulnerability status with an integer value easier to understand and allows spatial comparability. This framework could be improved further preferably through stakeholder consultations about the appropriateness of the indicators, indicator statuses, and their weights. An improved and well-agreed framework would assist in integrative policy formulation to reduce women’s vulnerability to cyclone disaster. Moreover, this approach could be adopted in vulnerability ranking/mapping for other disasters.
