Enterprise Social Media: Definition, History, and Prospects for the Study of Social Technologies in Organizations

Abstract: Social media are increasingly implemented in work organizations as tools for communication among employees. As these technologies begin to proliferate across the enterprise, it is important that we develop an understanding of how they enable and constrain the communicative activities through which work is accomplished because it is these very dynamics that constitute and perpetuate organizations. We begin by offering a definition of enterprise social media and providing a rough historical account of the various avenues through which these technologies have entered and continue to enter the workplace. We also review areas of research covered by papers in this special issue and papers on enterprise social media published elsewhere to take stock of the current state of out knowledge and to propose directions for future research.

Emotions and Teacher Identity: A poststructural perspective

Abstract: This article illustrates the significance of teachers' emotions in the construction of teacher identity by invoking a poststructuralist lens in discussing the place of emotion in identity formation. In suggesting a poststructuralist perspective of emotions and teacher identity, it is argued that teacher identity is constantly becoming in a context embedded in power relations, ideology, and culture. In theorizing about teacher identity two ideas are developed: first, that the construction of teacher identity is at bottom affective, and is dependent upon power and agency, i.e., power is understood as forming the identity and providing the very condition of its trajectory; and second, that an investigation of the emotional components of teacher identity yields a richer understanding of the teacher self. This discussion is motivated by a desire to develop analyses that investigate how teachers' emotions can become sites of resistance and self-transformation. The emphasis on understanding the teacher-self thro...

Determination of the Pore Size of Cell Walls of Living Plant Cells

Abstract: The limiting diameter of pores in the walls of living plant cells through which molecules can freely pass has been determined by a solute exclusion technique to be 35 to 38 angstroms for hair cells of Raphanus sativus roots and fibers of Gossypium hirsutum, 38 to 40 angstroms for cultured cells of Acer pseudoplatanus, and 45 to 52 angstroms for isolated palisade parenchyma cells of the leaves of Xanthium strumarium and Commelina communis. These results indicate that molecules with diameters larger than these pores would be restricted in their ability to penetrate such a cell wall, and that such a wall may represent a more significant barrier to cellular communication than has been previously assumed.

Habits in everyday life: thought, emotion, and action.

Abstract: To illustrate the differing thoughts and emotions involved in guiding habitual and nonhabitual behavior, 2 diary studies were conducted in which participants provided hourly reports of their ongoing experiences. When participants were engaged in habitual behavior, defined as behavior that had been performed almost daily in stable contexts, they were likely to think about issues unrelated to their behavior, presumably because they did not have to consciously guide their actions. When engaged in nonhabitual behavior, or actions performed less often or in shifting contexts, participants' thoughts tended to correspond to their behavior, suggesting that thought was necessary to guide action. Furthermore, the self-regulatory benefits of habits were apparent in the lesser feelings of stress associated with habitual than nonhabitual behavior.
