A utility-based power-control scheme in wireless cellular systems

Abstract: Distributed power-control algorithms for systems with hard signal-to-interference ratio (SIR) constraints may diverge when infeasibility arises. In this paper, we present a power-control framework called utility-based power control (UBPC) by reformulating the problem using a softened SIR requirement (utility) and adding a penalty on power consumption (cost). Under this framework, the goal is to maximize the net utility, defined as utility minus cost. Although UBPC is still noncooperative and distributed in nature, some degree of cooperation emerges: a user will automatically decrease its target SIR (and may even turn off transmission) when it senses that traffic congestion is building up. This framework enables us to improve system convergence and to satisfy heterogeneous service requirements (such as delay and bit error rate) for integrated networks with both voice users and data users. Fairness, adaptiveness, and a high degree of flexibility can be achieved by properly tuning parameters in UBPC.

Beyond persuasion: A proposal for an invitational rhetoric

Abstract: Most traditional rhetorical theories reflect a patriarchal bias in the positive value they accord to changing and thus dominating others. In this essay, an alternative rhetoric—invitational rhetoric—is proposed, one grounded in the feminist principles of equality, immanent value, and self‐determination. Its purpose is to offer an invitation to understanding, and its communicative modes are the offering of perspectives and the creation of the external conditions of safety, value, and freedom.

Food Insecurity Is Associated with Increased Risk of Obesity in California Women

Abstract: Food insecurity, the limited or uncertain availability of nutritionally adequate and safe foods, may be associated with disordered eating and a poor diet, potentially increasing risk for obesity and health problems. Patterns of food insecurity in California women are described and relationships between food insecurity and obesity (body mass index > or = 30 kg/m(2)) are evaluated using data from the 1998 and 1999 California Women's Health Survey. A total of 8169 women aged > or = 18 y were randomly selected and interviewed by telephone. Food insecurity was evaluated by use of four questions adapted from the U.S. Household Food Security Module. Logistic regression was used to examine the relationship between food insecurity and obesity, controlling for income, race/ethnicity, education, country of birth, general health status and walking. Food insecurity without hunger affected 13.9% of the population and food insecurity with hunger, 4.3%. Almost one fifth (18.8%) of the population was obese. Obesity was more prevalent in food insecure (31.0%) than in food secure women (16.2%). Food insecurity without hunger was associated with increased risk of obesity in whites [odds ratio (OR) = 1.36] and others (OR = 1.47). Food insecurity with hunger was associated with increased risk of obesity for Asians, Blacks and Hispanics (OR = 2.81) but not for non-Hispanic Whites (OR = 0.82). Food insecurity is associated with increased likelihood of obesity and risk is greatest in nonwhites.
