“Battle of the Mei-Meis”

On May 7, 2011, Singapore held its 16th General Election. The ruling People’s Action Party (PAP) predictably secured a landslide victory, and yet the result was contextually historic, with the opposition winning six seats from a possible eighty-seven—the largest loss for the PAP since political independence in 1965. At the centre of the General Election was a persistent media buzz surrounding two young female candidates: Tin Pei Ling of the People’s Action Party and Nicole Seah of the National Solidarity Party. While the former suffered sustained criticism, the latter received sustained praise. This article seeks to analyze the manner in which these two women were positioned as inverse feminine subjects within the mediascape. The analysis emerges from data collected from 194 sources which appeared online between March 29, 2011 and May 8, 2011, comprising political blogs, discussion forums, articles, and reports from online news sites. It aims to reveal how the gendered media constructions of, and public responses to, both women interpolate a diametrically opposed positive and negative binary of womanhood which functions to: (1) reify national discourses of ideal femininity; and (2) corroborate regional conceptualizations of “good” and “bad” feminine subjectivities.     

Assessing families and other client systems in community-based programmes: development of the CALF

Programmes providing services to children and families often face the challenge of assessing not only the child referred, but also the child’s family system and its individual members. Recognizing that household/family members can cause, contribute to or affect a child’s problems requires that human service agencies utilize assessment tools capable of assessing family members across the lifespan. The literature references many assessment tools used by clinical programmes in mental‐health settings that are not well suited to use in social service agencies with multidisciplinary staff at different skill levels. As a response to this dilemma, the authors have developed the Collaborative Assessment of Life Functioning (CALF), a user‐friendly tool that assesses various areas of life functioning. Based on Maslow’s motivation theory, person‐in‐environment and systems theories, the CALF can be used with various client systems. This paper describes the development of the tool, its purpose and use, the importance of assessment tools in the helping process and considerations for agencies wishing to use an assessment tool like the CALF. The authors also discuss the applicability of the CALF in human services and social service agency settings and with diverse client populations.     

Consumer processing of hazard warning information

Using data obtained from a field experiment involving 957 consumers, this study investigates the linkage between hazard warnings and precautionary behavior, as well as the structure of the information about product usage and risks that consumers store in their memories. Through the use of a methodology based on an open-ended memory recall task, we measure how consumer recall of information on product labels is affected by the type and format of the information and infer the structure by which this information is stored in their memory. The methodology also allows us to explore the importance of limitations on consumers' cognitive abilities. In particular, we find that consumers substitute greater recall of risk information for recall of usage information, indicating a tradeoff among the different types of information conveyed on a product label. We also found that in the case of cluttered labels, as typified by many existing product labels, information overload results, which may make labeling ineffective in achieving its intended informational objective.     

Interviewer as instrument: accounting for human factors in evaluation research

This methodological study examines an original data collection model designed to incorporate human factors and enhance data richness in qualitative and evaluation research. Evidence supporting this model is drawn from in-depth youth and adult interviews in one of the largest policy/program evaluations undertaken in the United States, the Drug, Alcohol, and Tobacco Education evaluation (77 districts, 118 schools). When applying the explicit observation technique (EOT)--the strategic and nonjudgmental disclosure of nonverbal human factor cues by the interviewer to the respondent during interview--data revealed the observation disclosure pattern. Here, respondents linked perceptions with policy or program implementation or effectiveness evidence. Although more research is needed, it is concluded that the EOT yields richer data when compared with traditional semistructured interviews and, thus, holds promise to enhance qualitative and evaluation research methods. Validity and reliability as well as qualitative and evaluation research considerations are discussed.     

Transformational Leadership Education and Agency Perspectives in Business School Pedagogy: A Marriage of Inconvenience?

We critique transformational leadership education in university business schools based on a literature review, a study of the websites of 21 leading business schools, and an analysis of two presentations to business school students at Massachusetts Institute of Technology and Stanford University by the former CEO of General Electric, Jack Welch. Our critique draws attention to the unresolved tension between two motivating ideas that underpin much teaching in business schools: collective interest ideas that permeate transformational leadership education; and self-interest ideas derived from agency theory. Transformational leadership tends to be depicted as a process by which leaders exert a 'top-down' influence over the activities of others, while simultaneously asserting that their organizations have a common purpose and pursue a collective interest. We highlight the risk that business schools are producing graduates who will attempt to appeal to common needs (guided by precepts of transformational leadership) but who will simultaneously enact contradictory performance management systems (guided by agency theory). We encourage business school educators in leadership to adopt approaches which are more critical, relational and reflexive. We suggest some general directions for an alternative leadership prospectus, based on followership, the promotion of critical upward communication within organizations, and the recognition of leadership as a contested, discursive and co-constructed phenomenon.     

It's Only Temporary: Time Frame and the Dynamics of Creative Project Teams

The success of many knowledge‐intensive industries depends on creative projects that lie at the heart of their logic of production. The temporality of such projects, however, is an issue that is insufficiently understood. To address this, we study the perceived time frame of teams that work on creative projects and its effects on project dynamics. An experiment with 267 managers assigned to creative project teams with varying time frames demonstrates that, compared to creative project teams with a relatively longer time frame, project teams with a shorter time frame focus more on the immediate present, are less immersed in their task and utilize a more heuristic mode of information processing. Furthermore, we find that time frame moderates the negative effect of team conflict on team cohesion. These results are consistent with our theory that the temporary nature of creative projects shapes different time frames among project participants, and that it is this time frame that is an important predictor of task and team processes.     

Reconceptualizing and expanding the positive feedback network effects model: A case study

During the 1980s, economists developed the concept of positive network effects and switching costs as the key dynamics of de facto standards competition. They concluded that a positive feedback loop usually “tips” a market to the standard with the most users and complementary assets. While recent scholars have acknowledged that not all markets tip, and suggested some possible limitations on this phenomena, these limitations have not been integrated systematically into a model for competition in these industries. Using examples drawn from the standards contests of the past 20 years, this case study develops an integrated model for competition in these industries.     

Measuring resetting of brain dynamics at epileptic seizures: application of global optimization and spatial synchronization techniques

Epileptic seizures are manifestations of intermittent spatiotemporal transitions of the human brain from chaos to order. Measures of chaos, namely maximum Lyapunov exponents (STL _max ), from dynamical analysis of the electroencephalograms (EEGs) at critical sites of the epileptic brain, progressively converge (diverge) before (after) epileptic seizures, a phenomenon that has been called dynamical synchronization (desynchronization). This dynamical synchronization/desynchronization has already constituted the basis for the design and development of systems for long-term (tens of minutes), on-line, prospective prediction of epileptic seizures. Also, the criterion for the changes in the time constants of the observed synchronization/desynchronization at seizure points has been used to show resetting of the epileptic brain in patients with temporal lobe epilepsy (TLE), a phenomenon that implicates a possible homeostatic role for the seizures themselves to restore normal brain activity. In this paper, we introduce a new criterion to measure this resetting that utilizes changes in the level of observed synchronization/desynchronization. We compare this criterion’s sensitivity of resetting with the old one based on the time constants of the observed synchronization/desynchronization. Next, we test the robustness of the resetting phenomena in terms of the utilized measures of EEG dynamics by a comparative study involving STL _max , a measure of phase (φ _max ) and a measure of energy (E) using both criteria (i.e. the level and time constants of the observed synchronization/desynchronization). The measures are estimated from intracranial electroencephalographic (iEEG) recordings with subdural and depth electrodes from two patients with focal temporal lobe epilepsy and a total of 43 seizures. Techniques from optimization theory, in particular quadratic bivalent programming, are applied to optimize the performance of the three measures in detecting preictal entrainment. It is shown that using either of the two resetting criteria, and for all three dynamical measures, dynamical resetting at seizures occurs with a significantly higher probability (α=0.05) than resetting at randomly selected non-seizure points in days of EEG recordings per patient. It is also shown that dynamical resetting at seizures using time constants of STL _max synchronization/desynchronization occurs with a higher probability than using the other synchronization measures, whereas dynamical resetting at seizures using the level of synchronization/desynchronization criterion is detected with similar probability using any of the three measures of synchronization. These findings show the robustness of seizure resetting with respect to measures of EEG dynamics and criteria of resetting utilized, and the critical role it might play in further elucidation of ictogenesis, as well as in the development of novel treatments for epilepsy.
