235. Statewide Races in Maryland: Unusual Beginnings of a New Era in Electoral Politics?

Author

Hill, Walter W.

Abstract

The article presents an examination into the racial political conditions of the U.S through the example of Maryland in its statewide office elections of 2002 and 2006. Details are given outlining the circumstances in both elections where an African American lieutenant governor was appointed and commentary is offered regarding its social-political significance. Specific details of the victories of Anthony G. Brown and Michael S. Steele are provided. The author hypothesizes that the presence of an African American politician on the statewide ticket promoted action within the swing-voter segment rather than the African American voter block.

237. Phosphorus and light colimit periphyton growth at subsaturating irradiances.

Abstract

1. This study investigated the combined effects of light and phosphorus on the growth and phosphorus content of periphyton. To investigate the potential for colimitation of algal growth by these two resources, diatom-dominated periphyton communities in large flow-through laboratory streams were exposed under controlled conditions to simultaneous gradients of light and phosphorus. 2. Periphyton growth rate was predictably light-limited by the subsaturating irradiances (12–88 μmol photons m−2 s−1) used in this experiment. However, phosphorus concentration also limited growth rate: growth increased hyperbolically with increasing soluble reactive phosphorus (SRP), reaching a threshold of growth saturation between 22 and 82 μg L−1. 3. Periphyton phosphorus content was strongly and nonlinearly related with SRP, reaching a maximum at 82 μg L−1 SRP. Contrary to the Light : Nutrient Hypothesis, periphyton phosphorus content did not decrease with increasing light, even at the lowest concentrations of SRP. Periphyton phosphorus was highly correlated with periphyton growth rate (Spearman's ρ = 0.63, P < 0.005). 4. Multiple regression analysis reinforced evidence of simultaneous light and phosphorus limitation. Both light and periphyton phosphorus content were significant variables in multiple regressions with growth parameters as dependent variables. Light alone accounted for 67% of the variance in periphyton biomass, and the addition of periphyton phosphorus as an additional independent variable increased the total amount of variance explained to 81%. 5. Our results did not support the hypothesis that extra phosphorus is required for photoacclimation to low light levels. Rather, the effect of additional phosphorus may have been to accommodate increased requirements for P-rich ribosomal RNA when growth was stimulated by increased light. The potential colimitation of periphyton growth by phosphorus and light at subsaturating irradiances has important implications in both theoretical and applied aquatic ecology.

247. VARIATIONS IN LEADER BEHAVIOR AS A FUNCTION OF TASK TYPE.

Abstract

The current leadership literature reflects a growing acceptance of contingency theories of leadership effectiveness which postulate that different leadership behaviors are required in different situations. Proponents of these theories generally attempt to define situations. Proponents of these theories generally attempt to define situational variables which influence the desirability of some, rather than other behaviors. [4, 7,13] One important question which these approaches have not answered is whether a leader can behave flexibly enough to cope with varied situations or whether it is necessary either to replace the leader as the situation changes or to modify the situation to fit the leader's capabilities. There is disagreement over this issue. On the one hand, Tannenbaum and Schmidt [11], Argyris [1] and Likert [10] explicitly or implicitly assume that leaders are capable of exhibiting a wide range of behavior. Fiedler [5], on the other hand, feels that leaders are not capable of varying their behavior very much. Although Hill [6] has presented evidence that subordinates perceive that their superiors would vary their behavior over four hypothetical problems, this question can be answered best by measuring actual leader behavior. The purpose of this paper is to shed some light on this question by presenting empirical evidence of variations in leader behavior over three different tasks. [ABSTRACT FROM AUTHOR]

248. The LPC Leader: A Cognitive Twist.

Abstract

The purpose of this paper is to develop further the rationale for Fiedler's prediction that a task-oriented (low LPC) leader will tend to be more effective where the situation is either very favorable or very unfavorable for the leader to exert influence and that a relations-oriented (high LPC) leader will tend to be more effective in situations intermediate in favorability. Specifically, this paper will attempt to clarify what the least preferred co-worker (LPC) score actually measures and will try to show how the behavior patterns of the two types of leaders differ.
