The Manner Result Complementarity and the Lexicalization Pattern of Chinese Motion Verbs

Rappaport Hovav and Levin (1998, 2010) propose manner/result complementarity hypothesis (MRC), i.e. verbs can not lexicalize manner and result simultaneously at a time. As to the encoding of motion events, Levin et al. (2009) also claim that manner of motion verbs across languages simply lexicalize manner and no direction is entailed. However, three basic motion verbs in Chinese--zǒu ‘walk’, pǎo ‘run’ and fēi ‘fly’, which are regarded as prototypical manner of motion verbs but also seem to lexicalize directed motion when used in some constructions. Then questions arise: do these verbs lexicalize direction of motion and are they counterexamples of the MRC? Based on evidence gained from a series of linguistic tests, this study argues that on the one hand different from views of Levin et al. (2009), the three manner of motion verbs can indeed lexicalize directed motion, but on the other hand they never encode the manner and direction of motion simultaneously and thus they are not counterexamples of the MRC. The fact that manner of motion verbs exhibiting similar lexicalization pattern can also be found in other languages indicates that the prototypical manner encoded in these verbs may be the conceptual condition for the special lexicalization pattern.

Contrasting parental color morphs increase regularity of prey deliveries in an African raptor

Disassortative mating in color-polymorphic raptors is a proposed mechanism for the maintenance of color polymorphism in populations. Selection for such a mating system may occur if there are fitness advantages of mating with a contrasting morph. In the black sparrowhawk (Accipiter melanoleucus), mixed-morph pairs may have a selective advantage because they produce offspring that have higher survival rates. Two hypotheses, which may explain the mechanism, are the “avoidance-image” and “complementarity” hypotheses. The first suggests that, within a predator’s territory, prey develop a search image for the more commonly encountered parental morph, for example, the male morph during incubation and brooding. Females of a contrasting morph to their partner would then have higher capture rates once they commence hunting in the later nestling phase. Thus, the “avoidance-image” hypothesis predicts higher provisioning rates for mixed-morph pairs. Alternatively, the “complementarity” hypothesis posits that different color morphs exploit different environmental conditions, allowing mixed-morph pairs to hunt under a wider range of conditions and predicts that food is delivered more consistently. We test these hypotheses using nest cameras to record prey delivery rates during the late nestling phase when both parents are hunting. We found support for the “complementarity” hypothesis, with mixed-morph pairs delivering food more consistently but not at a higher rate. This higher consistency in prey deliveries may explain the improved survival of the offspring of mixed-morph pairs and could, therefore, play a role in maintaining the stability of color polymorphism in this system.

The Effects of Smartphones on Well-Being: Theoretical Integration and Research Agenda

As smartphones become ever more integrated in people’s lives, a burgeoning new area of research has emerged on their well-being effects. We propose that disparate strands of research and apparently contradictory findings can be integrated under three basic hypotheses, positing that smartphones influence well-being by (1) replacing other activities (displacement hypothesis), (2) interfering with concurrent activities (interference hypothesis), and (3) affording access to information and activities that would otherwise be unavailable (complementarity hypothesis). Using this framework, we highlight methodological issues and go beyond net effects to examine how and when phones boost versus hurt well-being. We examine both psychological and contextual mediators and moderators of the effects, thus outlining an agenda for future research.

Employee involvement, financial participation and firm performance

Purpose The purpose of this paper is to investigate whether performance is enhanced if firms use employee involvement (EI) in decision-making and financial participation (FP) in an emerging market economy. Design/methodology/approach The authors use representative data for Estonian firms. The authors estimate diverse forms of production functions. Some are restricted to individual forms of EI (including membership on boards by nonmanagerial employees) or individual forms of FP (such as employee ownership and profit sharing). To investigate the complementarity hypothesis findings, the authors construct systems of EI and FP and estimate diverse specifications. Findings For individual forms of EI, cross-sectional estimates indicate that alone, typically such mechanisms have little impact. However, panel estimates do provide support for some forms of FP such as employee ownership and profit sharing increasing business performance. Tests of the complementarity hypothesis provide only weak evidence in support of the synergies between EI and FP. Research limitations/implications Together with the results from related studies, the findings support the more general finding that FP practices have positive effects on productivity; the limited impact of EI alone and weak evidence for complementarities suggest an important role for the institutional context in accounting for the effectiveness of the mechanisms underlying EI and thus to the differences in the impact of EI and FP across institutional contexts; reinforce findings from other studies of emerging market economies of inertia in EI and FP practices during early transition. Originality/value This is the first study for a former transition economy/emerging market economy that uses detailed information on EI and FP to investigate individual and complementary effects.

Manner and Result in English Verb Roots

Manner/result complementarity hypothesis (MRC) proposed by Rappaport Hovav and Levin (1998, 2010) holds that a verb root cannot lexicalize manner and result meaning components simultaneously at a time. It has generated much interest and controversy among researchers. In spite of much evidence for it, researchers have also put forward a variety of arguments against it. This paper reviews arguments against the MRC hypothesis, reexamines the data these counterarguments are based on and reveals that these arguments do not pose real challenge for the MRC hypothesis. Counterexample verbs which are proposed to entail both manner and result actually lexicalize only one, either manner or result, and manner and result are indeed meaning component lexicalized in verb roots rather than aspectual focus.

Life in the Balance: Are Women’s Possible Selves Constrained by Men’s Domestic Involvement?

Do young women’s expectations about potential romantic partners’ likelihood of adopting caregiving roles in the future contribute to whether they imagine themselves in nontraditional future roles? Meta-analyzed effect sizes of five experiments (total N = 645) supported this complementarity hypothesis. Women who were primed with family-focused (vs. career-focused) male exemplars (Preliminary Study) or information that men are rapidly (vs. slowly) assuming greater caregiving responsibilities (Studies 1-4) were more likely to envision becoming the primary economic provider and less likely to envision becoming the primary caregiver of their future families. A meta-analysis across studies revealed that gender role complementarity has a small-to-medium effect on both women’s abstract expectations of becoming the primary economic provider ( d = .27) and the primary caregiver ( d = −.26). These patterns suggest that women’s stereotypes about men’s stagnant or changing gender roles might subtly constrain women’s own expected work and family roles.

Put the Phone Down

If there ever was a key to happiness, this key would open a door that leads straight to a rich social life. And in the era of smartphones, this key to social connection is in our pockets anytime and anywhere. Or is it? Using the experience sampling method (ESM), we explore the use of computer-mediated communication (CMC) in the context of face-to-face (FtF) social interactions, testing two competing hypotheses: (1) a complementarity hypothesis stating that more channels of communication should be associated with higher well-being and (2) an interference hypothesis stating that FtF interactions could be impoverished by adding computer-mediated channels of communication. We surveyed 174 millennials ( Mage = 19.28; range: 17–22) 5 times a day over a period of a week (4,508 episodes). When participants reported a mix of CMC and FtF socializing in the same episode, they felt worse and less connected than when solely interacting FtF.
