Abstract: Objective identification and description of mimicked calls is a primary component of any study on avian vocal mimicry but few studies have adopted a quantitative approach. We used spectral feature representations commonly used in human speech analysis in combination with various distance metrics to distinguish between mimicked and non-mimicked calls of the greater racket-tailed drongo, Dicrurus paradiseus and cross-validated the results with human assessment of spectral similarity. We found that the automated method and human subjects performed similarly in terms of the overall number of correct matches of mimicked calls to putative model calls. However, the two methods also misclassified different subsets of calls and we achieved a maximum accuracy of ninety five per cent only when we combined the results of both the methods. This study is the first to use Mel-frequency Cepstral Coefficients and Relative Spectral Amplitude – filtered Linear Predictive Coding coefficients to quantify vocal mimicry. Our findings also suggest that in spite of several advances in automated methods of song analysis, corresponding cross-validation by humans remains essential.

Al-Aali, A., & Teece, D. J. (2014). International Entrepreneurship and the Theory of the (Long-Lived) International Firm: A Capabilities Perspective. Entrepreneurship Theory and Practice, 38(1), 95–116.
Abstract: This paper expands on the Oviatt–McDougall framework of sustainable international ventures. It does so by relating the elements of the framework to existing scholarship on the multinational enterprise (MNE), a category that encompasses foreign direct-invested new ventures (FDINVs). The paper then incorporates entrepreneurship and capabilities into MNE theory and applies them to the FDINV. Strong dynamic capabilities coupled with good strategy work together to generate and sustain superior enterprise performance in fast-moving global environments. The resulting framework is used to revisit key questions in MNE/FDINV research such as the timing and mode of FDI.

Alvarez, S. A., & Barney, J. B. (2014). Entrepreneurial Opportunities and Poverty Alleviation. Entrepreneurship Theory and Practice, 38(1), 159–184.
Abstract: Entrepreneurial activity does not always lead to economic growth. While improvements have been made to human capital, property rights protection, and access to financial capital in abject poverty contexts with the assumption that they will increase entrepreneurial activity, the results have been mixed. More recently, many entrepreneurs interested in poverty alleviation are crossing borders to engage in initiatives aimed at reducing poverty internationally. These efforts have also had mixed results. This paper posits that one reason is that entrepreneurial opportunities and their wealth creation potential vary, and the impact of exploiting these opportunities on economic growth in poverty contexts can also vary. This paper identifies self-employment opportunities, often exploited in abject poverty, that do not lead to sustainable growth solutions. Alternatively, discovery and creation opportunities while difficult to exploit in poverty contexts hold the greatest potential for significant economic impact.

Anctil, A., Franke, A., & Bêty, J. (2014). Heavy rainfall increases nestling mortality of an arctic top predator: Experimental evidence and long-term trend in peregrine falcons. Oecologia, 174(3), 1033–1043.
Abstract: Although animal population dynamics have often been correlated with fluctuations in precipitation, causal relationships have rarely been demonstrated in wild birds. We combined nest observations with a field experiment to investigate the direct effect of rainfall on survival of peregrine falcon (Falco peregrinus) nestlings in the Canadian Arctic. We then used historical data to evaluate if recent changes in the precipitation regime could explain the long-term decline of falcon annual productivity. Rainfall directly caused more than one-third of the recorded nestling mortalities. Juveniles were especially affected by heavy rainstorms (≥8 mm/day). Nestlings sheltered from rainfall by a nest box had significantly higher survival rates. We found that the increase in the frequency of heavy rain over the last three decades is likely an important factor explaining the recent decline in falcon nestling survival rates, and hence the decrease in annual breeding productivity of the population. Our study is among the first experimental demonstrations of the direct link between rainfall and survival in wild birds, and clearly indicates that top arctic predators can be significantly impacted by changes in precipitation regime. © 2013 The Author(s).

Abstract: Lisa and John never envisioned that a luncheon held 20 years ago at their local high school would grow into The Empty Bowls Project, an international grassroots effort to fight hunger. The premise is simple in that potters, educators, students, and others create handcrafted bowls and serve a simple meal of soup and bread. In exchange for cash donations, attendees take home the bowl to recall all the empty bowls in the world. Monies raised are donated to community-based organizations working toward food security. The founders subsequently formed the nonprofit Imagine Render and now are considering their succession and future direction.

Armour, C., Elklit, A., Lauterbach, D., & Elhai, J. D. (2014). The DSM-5 dissociative-PTSD subtype: can levels of depression, anxiety, hostility, and sleeping difficulties differentiate between dissociative-PTSD and PTSD in rape and sexual assault victims? J Anxiety Disord, 28(4), 418–426.
Abstract: The DSM-5 currently includes a dissociative-PTSD subtype within its nomenclature. Several studies have confirmed the dissociative-PTSD subtype in both American Veteran and American civilian samples. Studies have begun to assess specific factors which differentiate between dissociative vs. non-dissociative PTSD. The current study takes a novel approach to investigating the presence of a dissociative-PTSD subtype in its use of European victims of sexual assault and rape (N=351). Utilizing Latent Profile Analyses, we hypothesized that a discrete group of individuals would represent a dissociative-PTSD subtype. We additionally hypothesized that levels of depression, anger, hostility, and sleeping difficulties would differentiate dissociative-PTSD from a similarly severe form of PTSD in the absence of dissociation. Results concluded that there were four discrete groups termed baseline, moderate PTSD, high PTSD, and dissociative-PTSD. The dissociative-PTSD group encompassed 13.1% of the sample and evidenced significantly higher mean scores on measures of depression, anxiety, hostility, and sleeping difficulties. Implications are discussed in relation to both treatment planning and the newly published DSM-5.
