Project Time in Silicon Valley

This article explores the pace of work for highly skilled workers who are employed in the high-tech industry of Silicon Valley. I link the temporal experiences of these workers to systems of domination at work, and to the particular characteristics of flexible specialization in the region. I ask four questions: How can the temporal rhythms of work be described? What factors shape these rhythms? Why do workers comply? How does this pace of work impact on other aspects of individuals' lives? I focus on the organization of work through project cycles, the de-linking of workers and organizations, and the ideology of individualism that constructs workers as entrepreneurs of their own careers as key factors that shape the erratic and quickened pace of work in Silicon Valley. I also show how this pace of work negatively affects other temporal spheres that individuals negotiate, most notably “bodily time” and the “interaction time” of social relationships.

     

Reducing Requirement Incorrectness and Coping with Its Negative Impact in Information System Development Projects

The negative impact of incorrect requirements on information system development (ISD) project performance has long been acknowledged. This study addresses the problem of incorrect requirements by proposing a model that combines the error reduction and coping concepts proposed by Field, Ritzman, Safizadeh, and Downing (2006) with the view that ISD is a knowledge‐intensive process. The model hypothesizes that when developers and users possess an understanding of each other's primary domain of knowledge, the prevention of incorrect requirements and the mitigation of the negative consequences of incorrect requirements tend to improve project performance. Data collected from 250 ISD professionals on the basis of their experiences of recently completed ISD projects confirmed all of our hypotheses. The results demonstrate that the eliciting of incorrect requirements can be reduced when users and developers possess cross‐domain understanding and when requirement analysis methodologies and techniques are available. Furthermore, the negative impact of incorrect requirements on project performance can be mitigated when developers have sufficient ISD knowledge and behavioral knowledge.     

When Race Becomes Even More Complex: Toward Understanding the Landscape of Multiracial Identity and Experiences

The explosion in the number of people coming from a multiracial heritage has generated an increased need for understanding the experiences and consequences associated with coming from a multiracial background. In addition, the emergence of a multiracial identity challenges current thinking about race, forcing scholars to generate new ideas about intergroup relations, racial stigmatization, social identity, social perception, discrimination, and the intersectionality of race with other social categories such as social class. The present issue brings together research and theory in psychology, sociology, education, culture studies, and public policy surrounding multiracial identity and introduces new advances in thinking about race, intergroup relations, and racial identity. In exploring multiracial identity, the issue will reexamine conceptualization of race and racial identification by examining the social experiences of multiracial individuals.     

Exploring Multiracial Individuals' Comfort with Intimate Interracial Relationships

This article explores the relationship between a heightened awareness of race as a social construct and comfort in interracial relationships across varying levels of intimacy among multiracial and monoracial individuals. Study 1 finds that multiracial individuals express higher levels of comfort in intimate interracial relationships than monoracial White and minority individuals. Study 2 finds that belief in race as a social construction mediates the differences between monoracial and multiracial individuals in their comfort in intimate interracial relationships. Implications of these findings for interracial relationships are discussed.     

Black adolescents' racial discrimination and suicide behaviors: Testing perceived school safety as a protective moderator

The current study examined associations between Black adolescents' (M_age = 15.55, SD = 1.23) racial discrimination and suicide behaviors (i.e., suicide ideation, suicide plan, and suicide attempts), and whether perceived school safety was a protective moderator. Furthermore, we tested gender differences in relations, which were not significant. Racial discrimination predicted greater suicide behaviors, and school safety informed less suicide behaviors. School safety moderated the relation between discrimination and suicide plan, such that at low school safety, discrimination predicted having a suicide plan but was not significant at high school safety. Furthermore, school safety moderated the relation between discrimination and suicide attempts. At low school safety, discrimination predicted more suicide attempts, but was not significant at high school safety.     

Sample size re-estimation without unblinding for normally distributed outcomes with unknown variance

Monitoring clinical trials in nonfatal diseases where ethical considerations do not dictate early termination upon demonstration of efficacy often requires examining the interim findings to assure that the protocol-specified sample size will provide sufficient power against the null hypothesis when the alternative hypothesis is true. The sample size may be increased, if necessary to assure adequate power. This paper presents a new method for carrying out such interim power evaluations for observations from normal distributions without unblinding the treatment assignments or discernably affecting the Type 1 error rate. Simulation studies confirm the expected performance of the method.     

A two-stage sequential design and analysis for comparing binomial rates with possibly random dropouts

Many clinical trials involve two-stage sequential designs with one interim analysis (Elashoff and Reedy, 1984, Biometrics 41, 791-795.) In this paper we present a situation where events are counted only at two fixed calendar time points and some patients may dropout during the time intervals. In the two-stage case, naive application of Tsiatis’s (1984, JASA 77, 855-861) logrank and Wilcoxon tests, which are for continuous survival time, is shown to lead to conservative type-I error rates and lower power. The two-stage sequential boundaries can also be calculated directly, rather than by simulation as was done by DeMets and Gail (1985, Biometrics 41, 1039-1044) with the assumption of some survival models, and are shown to be more flexible than the Pocock (1977, Biometrika 64, 191-199) and O’Brien-Fleming (1983, Biometrics 35, 549-556) boundaries since the former do not require an assumption on the correlation of the test statistics for the two stages. Repeated confidence intervals are also discussed. The design and approach are motivated by clinical trials studying treatment effects on vertebral fracture rates in elderly osteoporotic women. An example (Tilyard, et al. New England Journal of Medicine, 1992) is given to illustrate the method.     

Associations of Alcohol and Marijuana Use With Condom Use Among Young Adults: The Moderating Role of Partner Type

This study used multiple levels of analysis to examine associations of alcohol and marijuana (AM) use with condom use, including the moderating role of partner type, in a general sample of 754 sexually active young adults (mean age = 18.6, SD = 0.63; 77% non-White). Multivariable models examined associations over the past 30 days (global) and at the most recent sexual event (event specific). Over the past 30 days, participants who had a recent casual partner and used both substances reported a higher proportion of condom-protected sexual events during this period compared to AM nonusers, whereas those who had a recent steady partner and used alcohol, marijuana, or both substances reported a lower proportion of condom-protected sexual events compared to AM nonusers. At the most recent sexual event, participants who used both substances were four times more likely than AM nonusers to have condom-protected sex if the event involved a casual partner; however, there were no significant associations if the event involved a steady partner. Marijuana use, particularly combined with alcohol use, deserves greater attention in the context of condom use. Future research should consider different levels of analysis and partner types to fully understand these complex associations.     

Lost Agency for Change: The Diasporic Identity in Yizhou's Shui Community

This paper discusses how an incorporated ethnic community has gradually lost its agency for change or subjectivity to face the state. Contrary to what a postcolonial writer wants to see, in the diasporic Shui community of Yizhou (a city in China's Guangxi Autonomous District) there is a lack of agency for change or self-empowerment. The paper reports how the Shui identity is reduced to a by-product of ancestor worship within each family. The loss of agency for change and willing acculturation do not necessarily confirm the state-promoted modernization theory's linear historiography. What the Shui example proves is that the agency for change cannot be taken for granted. Although the hybrid component in the Shui ethnicity is not felt today, the chances that some revived ethnic consciousness can reinvent cultural customs should not be ruled out, as long as the Shui communities continue to carry the name of Shui. The invention of ‘The Shui people grabbing the flower lamp’, and the interpretation of keeping old trunks in the ancestors’ place are two such possible starting points. However, hybridity of this sort is reinvented from, and not embedded in, their identity. Nevertheless, the quest for being different from the larger community is both a matter of internal need and an external construction. This is why the simple name of Shui cannot guarantee itself as a basis for revival.     

Identity Adaptiveness: Affect Across Multiple Identities

Most empirical work that examines the effects of stereotypes on targets considers only one of a target's many social identities. This study examined how individuals implicitly affectively orient themselves toward their social identities in situations in which one or another of these identities is relatively adaptive. An adaptive identity is one associated with stereotypes that predict desirable performance in a given context. One hundred and twenty-one Asian American females generated ethnicity- and gender-related memories in contexts in which their gender identity was relatively adaptive, their ethnic identity was relatively adaptive, or neither identity was relatively adaptive. Self-reported affect expressed in these memories was analyzed. In a context in which their ethnic identity was adaptive, participants generated more positive ethnicity-related memories than gender-related memories. In contrast, in a context in which their gender identity was adaptive, participants generated more positive gender-related memories than ethnicity-related memories. When neither identity was adaptive participants expressed similar affect toward both. Similar results were found when blind raters coded memory affect. Findings suggest that stereotypes and different social contexts do not simply result in targets' "identification" or "disidentification" along a single dimension of identity, but rather prompt a reorientation of implicit affect across their multiple identities.
