Does Downloading PowerPoint Slides Before the Lecture Lead to Better Student Achievement?: Reply
No full textThis reply responds to a comment by Cannon (2011) that opens the debate on consistency of the effect of downloading PowerPoint slides before lectures on students’ exam performance. Cannon (2011) points out potential endogeneity problems in Chen and Lin (2008) and attempts to explore the unconditional mean effect of downloading PowerPoint slides for the full sample. In this reply, we firstly argue that the estimates in our original article are consistent since the effect of interest is the “conditional†treatment effect but not the unconditional mean effect. We provide explanations for our rationale of estimating the “conditional†treatment effect. Secondly, we propose a modified downloading variable to replicate Cannon’s analysis. Our results suggest that downloading PowerPoint slides before the exam does not produce a significant effect on absent students’ exam performance which is different from the results in Cannon (2011). Our analysis does support Cannon’s argument that students fixed effects are different across different attendance status.

Kin Hubbard Cartoon
No full textIn those early years the Hoosier Salon was open to artists who had lived in Indiana for at least one year, and it quickly became a showplace for Indiana artists. On display were paintings in watercolor and oil, etchings, drawings, pastels, and cartoons. Throngs of people jammed the galleries to see the work of some of the best Hoosier cartoonists such as Harold Gray, Kin Hubbard, John T. McCutcheon, Gaar Williams and Fontaine Fox. Cartoon art was even used in magazines to publicize the event.Use of this image is restricted to projects related to Destination Indiana.

Does the kin orientation of a British woman’s social network influence her entry into motherhood?
No full textBACKGROUND The influence of family and friends on an individual's fertility has long been an important topic within demography. Researchers who focus on social network effects and evolutionary demography have shown a renewed interest in this issue in recent years. However, only a few studies have been conducted in contemporary low-fertility, resource-rich settings. OBJECTIVE This study investigates whether a British woman's entry into motherhood (i.e., her first birth) is influenced by the kin orientation of her close social network. Specifically, we test the prediction derived from evolutionary theory that individuals with a kin-oriented network will have higher fertility than those with fewer relatives in their close social networks. We consider two potential proximate mechanisms by which kin may influence fertility. First, relatives could provide practical resources, such as childcare, which reduce the costs of reproduction, thereby increasing fertility. Second, family members might communicate relatively pro-natal messages that could help to "persuade" childless women to become mothers. METHODS We use data from the British Household Panel Study (1992 to 2003), and base the degree of kin orientation on the number of relatives a woman includes when identifying her three closest non-household associates. We conduct a discrete-time event history analysis to measure the risk of firstbirth, controlling for household composition and socio-economic background.RESULTS We find that when a woman has more kin in her close social network, her risk of havinga first birth increases at all ages. This suggests that relatives may influence fertility behaviour in this contemporary resource-rich population. Both of our proposed proximate mechanismsmay be important in driving this effect. © 2013 Paul Mathews & Rebecca Sear
KIN-29(S517A) mutant rescues the small-body-size phenotype of <i>kin-29</i>.

KIN-29::GFP levels were overall lower in kin-29(S517A)::GFP, as evident both by lower gfp fluorescence in this strain and reduced anti-GFP staining. This difference may be explained by different copy numbers of the transgene or by different stability of KIN-29(S517A) in comparison with KIN-29(WT).

Sex-biased dispersal, kin selection and the evolution of sexual conflict.
No full textThis work was supported by Portuguese funds from Fundação para a Ciência e a Tecnologia through cE3c Unit FCT funding UID/BIA/00329/2013 and through SAMV Post-Doctoral Research Grant (SFRH/BPD/66042/2009), and by a Natural Environment Research Council Independent Research Fellowship (AG, Grant Number NE/K009524/1).There is growing interest in resolving the curious disconnect between the fields of kin selection and sexual selection. Rankin’s (2011, J Evol Biol 24, 71-81) theoretical study of the impact of kin selection on the evolution of sexual conflict in viscous populations has been particularly valuable in stimulating empirical research in this area. An important goal of that study was to understand the impact of sex-specific rates of dispersal upon the coevolution of male-harm and female-resistance behaviours. But the fitness functions derived in Rankin’s study do not flow from his model’s assumptions and, in particular, are not consistent with sex-biased dispersal. Here, we develop new fitness functions that do logically flow from the model’s assumptions, to determine the impact of sex-specific patterns of dispersal on the evolution of sexual conflict. Whilst Rankin’s study suggested that increasing male dispersal always promotes the evolution of male harm and that increasing female dispersal always inhibits the evolution of male harm, we find that the opposite can also be true, depending upon parameter values.Peer reviewe
Volatility Dynamics in Foreign Exchange Rates: Further Evidence from the Malaysian Ringgit and Singapore Dollar
No full textSingapore dollar are analyzed in this paper. Our approach can simultaneously capture the empirical regularities of persistent and asymmetric effects in volatility and timevarying correlations of financial time series. Consistent with the results of Tse and Tsui (1997), there is only some weak support for asymmetric volatility in the case of the Malaysian ringgit when the two currencies are measured against the US dollar. However, there is strong evidence that depreciation shocks have a greater impact on future volatility levels compared with appreciation shocks of the same magnitude when both currencies measured against the yen. Moreover, evidence of time-varying correlation is highly significant when both currencies are measured against the yen. Regardless of the choice of the numeraire currency and the volatility models, shocks to exchange rate volatility are found to be significantly persistent.Constant correlations; Exchange rate volatility; Fractional integration; Long memory; Bivariate asymmetric GARCH; Varying correlations
