Toward a Unified Framework of Perceived Negative Leader Behaviors Insights from French and British Educational Sectors

In this paper, we challenge the commonly held assumption that actors in the education sector are largely ethical, and that there is therefore little need to scrutinize leader behaviors in this sector. We also overcome past scholars’ tendencies to either focus selectively on positive leader behaviors, or to stay content with categorizing leader behaviors into effective and ineffective (if at all they do focus on negative leader behaviors). Using data (Critical Incidents) from three case studies previously conducted in eight British and French academic establishments, we show that not only do negative leader behaviors abound in the education sector, but they can also be differentiated into three types: (1) behaviors emanating from leaders’ lack of functional skills i.e., ineffective behaviors, (2) behaviors emanating from leaders’ insouciance toward harming the organization and its members i.e., dysfunctional behaviors, and (3) behaviors emanating from leaders’ lack of honesty, integrity, ethicality, and transparency i.e., unauthentic behaviors. We enrich current understanding on ineffective, dysfunctional, and unauthentic leader behaviors, and offer a unified (yet differentiated) framework of negative leader behaviors in the academic sector. Since each type of negative behavior emanates from different motivational drivers, different measures are required to curb them. These are also discussed. A comparison of our findings with those from leadership studies in other sectors reveals that negative leader behaviors in the education sector are quite similar to those in other sectors

Separation and characterization of saponins with adjuvant activity from Quillaja saponaria Molina cortex.

Abstract Saponins were purified from Quillaja saponaria Molina bark by silica and reverse phase chromatography. The resulting purified saponins were tested for adjuvant activity in mice. Several distinct saponins, designated QS-7, QS-17, QS-18, and QS-21, were demonstrated to boost antibody levels by 100-fold or more when used in mouse immunizations with the Ag BSA and beef liver cytochrome b5. These purified saponins increased titers in all major IgG subclasses. To determine optimal dose in mice for adjuvant response, QS-7 and QS-21 were tested in a dose-response study in intradermal immunization with BSA in mice; for both of these purified saponins, adjuvant response (determined by stimulation of ELISA titers to BSA) neared maximum at doses of 5 micrograms and was shown to plateau up to the highest dose tested, 80 micrograms. These purified saponins vary considerably in their toxicity, as assessed by lethality in mice; the main component, QS-18, being the most toxic. Saponins QS-7 and QS-21 showed no or very low toxicity in mice, respectively. None of these saponins stimulated production of reaginic antibodies. The monosaccharide composition of these saponins showed similar but distinct compositions with all four containing fucose, xylose, galactose and glucuronic acid. Predominant differences were observed in the quantities of rhamnose, arabinose, and glucose. Monomer m.w. (determined by size exclusion HPLC) were determined to range from 1800 to 2200.</jats:p

How Techniques of Neutralization Legitimize Norm- and Attitude-Inconsistent Consumer Behavior

In accordance with societal norms and values, consumers readily indicate their positive attitudes towards sustainability. However, they hardly take sustainability into account when engaging in exchange relationships with companies. To shed light on this paradox, this paper investigates whether defense mechanisms and the more specific concept of neutralization techniques can explain the discrepancy between societal norms and actual behavior. A multi-method qualitative research design provides rich insights into consumers' underlying cognitive processes and how they make sense of their attitude-behavior divergences. Drawing on the Ways Model of account-taking, which is advanced to a Cycle Model, the findings illustrate how neutralization strategies are used to legitimize inconsistencies between norm-conforming attitudes and actual behavior. Furthermore, the paper discusses how the repetitive reinforcement of neutralizing patterns and feedback loops between individuals and society are linked to the rise of anomic consumer behavior
