A second look at Agathis by Bowen, M, Whitmore, T

Mobile device sensorhistory as a second factor for authentication by Vaas, C

“…A common issue with these solutions is that they are vulnerable to relay attacks. We thus propose a second factor which is resilient to these kind of attacks. …”

Second-best renewable subsidies to de-carbonize the economy: commitment and the green paradox by Van der Ploeg, R, Rezai, A

“…Without commitment the second-best subsidy is set to the social benefit of learning. …”

Second-best carbon taxation in the global economy: the green paradox and carbon leakage revisited by Van der Ploeg, R

“…Unilateral second-best optimal carbon taxes exceed the first-best taxes due to an import tariff component. …”

Age-size effects in productive efficiency: a second test of the passive learning model by Mengistae, T

Simulating properties of the likelihood ratio test for a unit root in an explosive second order autoregression. by Nielsen, B, Reade, J

“…This paper provides a means of accurately simulating explosive autoregressive processes, and uses this method to analyse the distribution of the likelihood ratio test statistic for an explosive second order autoregressive process. Nielsen (2001) has shown that for the asymptotic distribution of the likelihood ratio unit root test statistic in a higher order autoregressive model, the assumption that the remaining roots are stationary is unnecessary, and as such the approximating asymptotic distribution for the test in the difference stationary region is valid in the explosive region also. …”

National hardwoods programme: report of the eighth meeting and second meeting of the Uneven-aged Silviculture Group 7 January 1988 by Savill, P

“…There are now several thousand hectares of woodland containing ash, birch, cherry and sycamore - in addition to beech and oak that could be converted into productive stands using systems of uneven-aged silviculture.</p> <p>The second reason why this joint programme is timely is the appearance of the report 'Beyond 2000' produced by the Forestry Industry Committee of Great Britain. …”

German trade finance in South America during the second industrial revolution. La Batalla de Buenos Aires, 1875-1913 by Kisling, W, Tena Junguito, A

Ethnic differences in COVID-19 mortality during the first two waves of the coronavirus pandemic: A nationwide cohort study of 29 million adults in England by Nafilyan, V, Islam, N, Mathur, R, Ayoubkhani, D, Banerjee, A, Glickman, M, Humberstone, B, Diamond, I, Khunti, K

“…We compared the differences in the risk of COVID-19 related death between ethnic groups in the first and second waves the of COVID-19 pandemic in England. …”

Inequality, interactions, and human development by Seth, S

“…The second form of inequality is important as dimensional interactions may alter individual-level evaluations as well as overall inequality. …”

Crank-Nicolson time-marching. by Giles, M

“…It also presents the Rannacher startup procedure which is required to achieve second order accuracy for the option value and its first and second derivatives, and discusses extensions to nonlinear and multi-factor applications.…”

On Thurston's Euler class one conjecture by Yazdi, M

“…In 1976, Thurston proved that taut foliations on closed hyperbolic 3-manifolds have Euler class of norm at most one, and conjectured that conversely, any integral second cohomology class with norm equal to one is the Euler class of a taut foliation. …”

Growth, renewables and the optimal carbon tax by Van der Ploeg, R, Withagen, C

“…We also offer some policy simulations for the first and second regime, which illustrate that with a lower discount rate more oil is left in situ and renewables are phased in more quickly. …”

Preschool quality and child development by Andrew, A, Attanasio, O, Bernal, R, Cardona-Sosa, L, Krutikova, S, Rubio-Codina, M

“…The first, which was designed by the government and rolled out nationwide, provided preschools with significant extra funding, mainly earmarked for hiring teaching assistants (TAs). The second additionally offered professional development training for existing teachers, delivered using a novel low-cost video-conferencing approach. …”

The political economy of economic policy advice by Dercon, S

“…It offers a framework for assessing how to maximize the economic development impact of advice, allowing for the political incentives of those in power. It argues for a ’second best’ analysis that looks to maximize development impact given political incentives and shows how standard advice, as often given by researchers or by advisors in government or from international organisations such as World Bank and IMF may not be this second best. …”

Uniform consistency of marked and weighted empirical distributions of residuals by Berenguer Rico, V, Nielsen, B, Johansen, S

“…These estimators describe the widespread practice of removing outlying observations from an intial estimation of the model of interest and updating the estimation in a second step by applying least squares to the selected observations. …”

Everything is uncertain and uncertainty is everything: strategic voting in simple plurality elections by Myatt, D, Fisher, S

“…Intuition tells us that strategic voting is most likely in marginal constituencies where the preferred party is a long way behind the second placed parity. Some formal theories suggest there should be complete desertion of all but two candidates (Palfrey 1989), or additionally that the second and third will have similar vote shares (Cox 1997). …”

Anomaly detection in networks with application to financial transaction networks by Elliott, A, Cucuringu, M, Luaces, M, Reidy, P, Reinert, G

“…We test the method first on synthetic networks which we generated, and second on a set of synthetic networks which were generated without the methods team having access to the ground truth. …”

The Time-crunch Paradox. by Sevilla-Sanz, A, Gimenez-Nadal, J

“…This finding is a challenge to the second shift argument, which suggests that increases in female labor market hours have not been compensated by equal decreases in household labor. …”

Everything is Uncertain and Uncertainty is Everything: Strategic Voting in Simple Plurality Elections. by Myatt, D, Fisher, S

“…Intuition tells us that strategic voting is most likely in marginal constituencies where the preferred party is a long way behind the second placed parity. Some formal theories suggest there should be complete desertion of all but two candidates (Palfrey 1989), or additionally that the second and third will have similar vote shares (Cox 1997). …”
