Resource Distribution in Multiple Attacks with Imperfect Detection of the Attack Outcome

This article extends the previous research of consecutive attacks strategy by assuming that an attacker observes the outcome of each attack imperfectly. With given probabilities it may wrongly identify a destroyed target as undestroyed, and wrongly identify an undestroyed target as destroyed. The outcome of each attack is determined by a contest success function that depends on the amount of resources allocated by the defender and the attacker to each attack. The article suggests a probabilistic model of the multiple attacks and analyzes how the target destruction probability and the attacker's relative resource expenditure are impacted by the two probabilities of incorrect observation, the attacker's and defender's resource ratio, the contest intensity, the number of attacks, and the resource distribution across attacks. We analyze how the attacker chooses the number of attacks, the attack stopping rule, and the optimal resource distribution across attacks to maximize its utility.     

Rainfall interception by Santa Monica's municipal urban forest

Effects of urban forests on rainfall interception and runoff reduction have been conceptualized, but not well quantified. In this study rainfall interception by street and park trees in Santa Monica, California is simulated. A mass and energy balance rainfall interception model is used to simulate rainfall interception processes (e.g., gross precipitation, free throughfall, canopy drip, stemflow, and evaporation). Annual rainfall interception by the 29,299 street and park trees was 193,168 m³ (6.6 m³/tree), or 1.6% of total precipitation. The annual value of avoided stormwater treatment and flood control costs associated with reduced runoff was $110,890 ($3.60/tree). Interception rate varied with tree species and sizes. Rainfall interception ranged from 15.3% (0.8 m³/tree) for a small Jacaranda mimosifolia (3.5 cm diameter at breast height) to 66.5% (20.8 m³/tree) for a mature Tristania conferta (38.1 cm). In a 25-year storm, interception by all street and park trees was 12,139.5 m³ (0.4%), each tree yielding $0.60 (0.4 m³/tree) in avoided flood control costs. Rainfall interception varied seasonally, averaging 14.8% during a 21.7 mm winter storm and 79.5% during a 20.3 mm summer storm for a large, deciduous Platanus acerifolia tree. Effects of differences in temporal precipitation patterns, tree population traits, and pruning practices on interception in Santa Monica, Modesto, and Sacramento, California are described.     

CONTESTING FAIRNESS AND FRAGMENTING GROUPS: CULTURAL NARRATIVES OF TAXATION AND CITIZENSHIP IN GLOBALISING AUSTRALIA

This paper explores the relationship between culturally mediated narratives of fairness, conceptions of the state, group and individual identities, citizenship and debates about globalisation in Australian perspectives on tax administration. It is based on a qualitative analysis of 2374 responses to a survey of attitudes to the Australian tax system. This paper emphasises that taxpayer's statements can be read as cultural acts that enrich our understanding of how people give meaning and significance to their lives. The majority of respondents reported that taxation should be levied fairly across social groups. However, this sense of fairness is being eroded by the widespread perception that the wealthy are avoiding their “fair share” of taxes. However, although citizens view tax administration as increasingly unfair, there is no evidence of wholesale disengagement from the system. The majority of people believe that the tax system has legitimacy and that it can be reformed. There is still scope for policy innovation that reinstates a sense of fairness, equity and balance to the tax system.     

Place-based urban ecology: A century of park planning in Seattle

This research responds to calls from within the field of urban ecology to explicitly incorporate humanities-based research in order to achieve robust interdisciplinarity. Our research provides an example of a place-based urban ecological analysis. We use this framework to analyze over a century of park planning and development within the city of Seattle. We identify four eras of park planning that are linked by a comprehensive 100-year park plan. This case study examines how the political, cultural, and economic aspects of park planning have produced and been influenced by long-term trends and historical contingencies. This research also offers practical insights for effective contemporary urban planning, emphasizing the need for flexible and adaptive long-term plans when confronted with unpredictable events, emerging political arrangements, changing cultural priorities, and shifting fiscal climates.     

A Content Analysis of Violence in American War Movies

In a content analysis of movie violence, we randomly selected twelve top-grossing American war films from four decades (1970 to 2002). We coded for implements of violence, length of violence, gore, and violence directed at noncombatants. We hypothesized that recently released war movies would be more violent than those released earlier. We found that films released since 1990 did contain more violence compared to others. Further, the intensity of gore increased in recently released movies.     

The interaction of depersonalization and deindividuation

Abnormal experiences of the self defined here in terms ofdepersonalization may predispose individuals to aggressive behavior in situations that further alter their self-awareness. Conditions that raise self-awareness may inhibit the aggressive behavior of individuals prone to these abnormal experiences of self. In the current research, individuals prone to a distorted body image were least likely to express attitudes reflecting verbal hostility when their self-awareness was raised. Individuals prone to a sense of unreality about others were most likely to express attitudes that reflect physical aggression when their sense of social identity was raised. However, these attitudes were less likely in individuals prone to self-criticism whose social identity was enhanced. The results suggest that a multidimensional construct of depersonalization may aid in the prediction of aggressive behavior that is facilitated by situations that alter the individual’s sense of self.     

The Effects of Managerial Succession on Organizational Performance

Boyne and Dahya (2002) posit that the means, motives, and opportunitiesavailable to top managers will affect their ability to impactorganizational performance. In this analysis, I test the theoryposited by Boyne and Dahya and expand the model by exploringwhether the performance effects of executive succession differbetween an internal promotion and an external hire. Using Texasschool superintendents as the managers in question, I use pooled,time-series data to test both the immediate and the long-termeffects of managerial succession on performance. The findingsreveal that an immediate, negative effect of executive successionis present only in the case of an externally hired replacementand that the long-term effect of managerial change on organizationalperformance is positive. These findings suggest that publicmanagerial succession does influence organizational performance.     

Struck by speech revisited: Embodied stance in jurisdictional discourse1

This paper illustrates how stance functions as a semiotic resource that feeds into and mediates institutional context. I consider stance not only as linguistic expression but as interactive, bodily engagement, synchronized in multimodal layers of participation. Using data from a focus group interview, I examine how stance emerges in the collaborative rhythms of linguistic, paralinguistic and, most prominently, embodied conduct between speaker and listener to index socio‐cultural knowledge about the jurisdictional division of labor among legal professionals. Drawing on Charles Frake's classic ‘Struck by speech,’ I illustrate not only how a speaker strikes his listener with speech, but also how the body of the listener displays being struck.
