On the Nature and Importance of Cultural Tightness-Looseness

Cross-cultural research is dominated by the use of values despite their mixed empirical support and their limited theoretical scope. This article expands the dominant paradigm in crosscultural research by developing a theory of cultural tightness-looseness, the strength of social norms and degree of sanctioning within societies, and advancing a multilevel research agenda for future research. Through an exploration of the top-down, bottom-up, and moderating impact that societal tightness-looseness has on individuals and organizations, as well as on variability across levels of analysis, the theory provides a new and complementary perspective to the values approach

Negotiating Relationally: The Dynamics of the Relational Self In Negotiations

Although negotiation research is thriving, it has been criticized as having an arelational bias—emphasizing autonomy, competition, and rationality over interdependence, cooperation, and relationality. In this article, we advance a new model of relationality in negotiation. Drawing on research in social psychology, we describe the construct of relational self-construals (RSC) and present a temporal model of RSC and negotiation. After delineating the conditions through which RSC becomes accessible in negotiation and conditions that inhibit its use, we discuss how RSC affects negotiators\u27 pre-negotiation psychological states, early and later tactics, and negotiation outcomes. We illustrate a number of distinct relational dynamics that can occur based on the dyadic composition of RSC, each of which brings distinct benefits and costs to the negotiation table. Implications for the science and practice of negotiation are discussed

A molecular phylogeny of Southeast Asian Cyrtandra (Gesneriaceae) supports an emerging paradigm for Malesian plant biogeography

The islands of Southeast Asia comprise one of the most geologically and biogeographically complex areas in the world and are a centre of exceptional floristic diversity, harbouring 45,000 species of flowering plants. Cyrtandra, with over 800 species of herbs and shrubs, is the largest genus in the family Gesneriaceae and is one of the most emblematic and species-rich genera of the Malesian rainforest understorey. The high number of species and tendency to narrow endemism make Cyrtandra an ideal genus for examining biogeographic patterns. We sampled 128 Cyrtandra taxa from key localities across Southeast Asia to evaluate the geo-temporal patterns and evolutionary dynamics of this clade. One nuclear and four chloroplast regions were used for phylogenetic reconstruction, molecular dating, and ancestral range estimation. Results from the dating analysis suggest that the great diversity of Cyrtandra seen in the Malesian region results from a recent radiation, with most speciation taking place in the last five million years. Borneo was recovered as the most likely ancestral range of the genus, with the current distribution of species resulting from a west to east migration across Malesia that corresponds with island emergence and mountain building. Lastly, our investigation into the biogeographic history of the genus indicates high levels of floristic exchange between the islands on the Sunda shelf and the important role of the Philippines as a stepping stone to Wallacea and New Guinea. These patterns underlie much of the plant diversity in the region and form an emerging paradigm in Southeast Asian plant biogeography

Disentangling the Fairness & Discrimination and Synergy Perspectives on Diversity Climate: Moving the Field Forward

We provide a theory-driven review of empirical research in diversity climate to identify a number of problems with the current state of the science as well as a research agenda to move the field forward. The core issues we identify include (a) the fact that diversity climate is typically treated as unidimensional, whereas diversity research would suggest that there are two major perspectives that could be reflected in diversity climate—efforts to ensure equal employment opportunity and the absence of discrimination versus efforts to create synergy from diversity; (b) a tendency to let the level of analysis (individual psychological climate or shared team or organizational climate) be dictated by convenience rather than by careful theoretical consideration, thus sidestepping key issues for research concerning the causes and consequences of the sharedness, or lack thereof, of diversity climate perceptions; and (c) the tendency to include diversity attitudes and other nonclimate elements in climate measures even though they are different from climate both conceptually and in their antecedents and consequences. The research agenda we advance suggests a need both for different operationalizations and for new research questions in diversity climate, diversity, and relational demography research

Flexible control of the Peierls transition in metallic C60_{60} polymers

The metal-semiconductor transition of peanut-shaped fullerene (C$_{60}$) polymers is clarified by considering the electron-phonon coupling in the uneven structure of the polymers. We established a theory that accounts for the transition temperature $T_c$ reported in a recent experiment and also suggests that $T_c$ is considerably lowered by electron doping or prolonged irradiation during synthesis. The decrease in $T_c$ is an appealing phenomenon with regard to realizing high-conductivity C$_{60}$-based nanowires even at low temperatures.Comment: 3 pages, 3 figure

Whiteboard Cleaning Task Realization with HOAP-2

The controller has a motion feedback control loop for the four arm joints and a force feedback control loop for the ankle joint. The desired motion/force trajectories are obtained via kinesthetic teaching by a human, followed by a learning phase. During skill demonstration, the arm joints are made compliant while the robot balances using ankle/hip strategies. Experimental data demonstrate the feasibility of the method
