ResumenLos conjuntos artefactuales de los sitios de cazadores-recolectores que habitaron el humedal del Paraná inferior durante el Holoceno reciente cuentan con una gran variedad de puntas líticas y óseas, destacándose entre estas últimas las puntas planas pedunculadas, las bipuntas y las puntas ahuecadas. El objetivo último de este trabajo es evaluar la relación que habrían tenido dichas piezas con los diferentes sistemas de armas y estrategias generadas para la captura de las presas. Para ello, en primer lugar se evaluaron las estructuras físicas, métricas, morfológicas y microscópicas de los distintos grupos morfológicos de puntas arqueológicas proponiendo su asociación con determinados sistemas de armas. A partir de ello, desarrollamos un programa experimental con el objetivo de evaluar la performance de cada uno bajo las condiciones esperadas. Palabras claves: Humedal del Paraná Inferior, Sistemas de armas, Análisis funcional. AbstractTool assemblages from sites of hunter-gatherers that inhabited the low Paraná wetland during late Holocene times have a great variety of lithic and bone points. Among these last ones, we highlight the presence of stemmed points, bipoints and drilled points. The main aim of this paper is to evaluate the link between these points and singular weapon systems and strategies developed for prey capture. For
This study investigates the effect of the alignment between corporate, operational, and information systems strategies and firm performance. Data were collected from the application of 138 questionnaires to large utility companies in the Australian electricity sector. In the analysis, modeling using structural equations was used to establish the dependency relationship between the variables. The results suggest that aligning operational and information systems strategies can improve firm performance. Likewise, no direct effect of corporate strategy on the firm performance was found.
PurposeThis article explores how strategy formulation affects firm performance to determine whether rational/analytical strategy formulation is more effective than emergent/reflexive strategy formulation. Additionally, the article assesses if such superiority holds for different cultural contexts.Design/methodology/approachMeta-analysis was performed using the Raju, Burke, Norman, and Landis (RBNL) procedure applied to a dataset of 43 empirical studies reporting 54 effect sizes on strategy–performance relationships.FindingsImplementing a formal strategy formulation process positively relates to firm performance. Rational/analytical formulation approaches are more effective than emergent/reflexive approaches in enhancing firm performance, especially for cultures with low future orientation, high uncertainty avoidance, and high power distance.Research limitations/implicationsThe reduced number of published empirical studies limited the scope and generalizability of the results across countries, industries, or firms. This limitation might be especially true for Latin American firms given the absence of relevant studies in this region. Another potential limitation is related to the distinction between strategy formulation and strategy implementation. Given the empirical nature of the studies meta-analyzed, strategic tools are used as a proxy to determine the formulation approach.Practical implicationsFirms that operate in short-term oriented, uncertainty-avoiding, and elitist cultures should favor implementing rational/analytical strategy formulation techniques rather than emergent/reflexive approaches. Although prescriptive recommendations are limited by the lack of studies in Latin America, firms in this region would seem to be better off using rational/analytical strategy formulation approaches.Originality/valueThese findings provide a partial explanation for the varying results yielded by strategy formulation and suggest cultural contexts in which rational/analytical strategy formulation should be more effective than emergent/reflexive approaches.
Este artículo reflexiona sobre la política de las asignaciones familiares en Uruguay. Está vigente desde 1943, fue ajustada mediante el uso de las tecnologías y modificada en sus principios originales en 2005, con la llegada del gobierno del Frente Amplio. Al mismo tiempo, se busca analizar cómo el desarrollo tecnológico, mediante el instrumento de Índice de Carencias Críticas (ICC), que tiene por propósito elegir a los hogares en situación de vulnerabilidad socioeconómica que le son entregadas las asignaciones familiares, modificó la Administración pública uruguaya, las relaciones laborales y la organización del trabajo. En términos metodológicos se revisan leyes de 1943, 2005 y 2007, además de fuentes secundarias de apoyo que evidencien el tipo de personas beneficiarias y recorrido de las asignaciones. La incorporación de las tecnologías tiende a despolitizar la pobreza, mientras que la vigilancia y supervisión de las asignaciones recae en el operador terminal, quien se encarga de la supervisión del software y recolección de los datos digitales.
