O objetivo deste trabalho foi correlacionar a precipitação (março a julho) de um grupo de postos homogêneos do setor leste do Nordeste do Brasil (NEB) com Anomalia de Temperatura da Superfície do Mar (ATSM) e identificar áreas de influência deste parâmetro nas chuvas da região. O período de estudo foi de 1945 a 1985 e a análise mostrou influência do Atlântico e Pacífico sobre as chuvas do setor leste, sendo a correlação do Atlântico maior, principalmente na área do Dipolo (correlação maior que 0,6, significativa a p < 0,05). Os modos zonal e meridional, descritos por Servain & Arnault (1995) foram detectados durante análises feitas com defasagem temporal ("lags"). No Oceano Pacífico Tropical Leste se encontrou correlações negativas indicando a presença dos ramos descendentes da célula de Walker no setor leste do NEB.

Is the structure of a retailing system dependent upon selected characteristics of the country served? The author's evidence affirms this hypothesis. The results reported may have important strategic implications for multinational retailers by serving as a base for forecasting. Temporal lags in the development of retail systems are found to approach the same length as lags in certain environmental factors.

Does X affect Y? Answering this question is particularly difficult if reverse causality is looming. Many social scientists turn to panel data to address such questions of causal ordering. Yet even in longitudinal analyses, reverse causality threatens causal inference based on conventional panel models. Whereas the methodological literature has suggested various alternative solutions, these approaches face many criticisms, chief among them to be sensitive to the correct specification of temporal lags. Applied researchers are thus left with little guidance. Seeking to provide such guidance, we compare how different panel models perform under a range of different conditions. Our Monte Carlo simulations reveal that unlike conventional panel models, a cross-lagged panel model with fixed effects not only offers protection against bias arising from reverse causality under a wide range of conditions but also helps to circumvent the problem of misspecified temporal lags.
