Correa, Patricio Ramírez;Cruz, Rosario García;
JISTEM - Journal of Information Systems and Technology Management , 2005, DOI: 10.1590/S1807-17752005000300002
Abstract: the study presents a systematic literature review on the implementation of erp systems. the analyses are based on 168 articles published in isi journals. firstly, the course of investigation on the phenomenon is investigated. then, methodologies under use are specified in the analysis: field work - statistical technique and variables; case studies - the type of design and study problem; conceptual works - their impact on literature. additionally, critical success factors proposed for the implementation of erp systems are summarized. lastly, with the purpose of supporting the development of future assumptions, some conclusions are provided on the scientific background for the study. a general analysis concludes that publications on erp system implementation show a clear expansion trend, and are concentrated in information system journals. empirical studies are privileged, with case studies used more frequently. organizations under study are usually multinationals in the industrial sector. based on that review, one concludes that: 1- organization size plays a key role in erp systems implementation; 2- the factors that affect late erp adoption differ from those that affect early implementation; 3- cultural collision can be felt at erp implementation; 4- diligent studies on success factors in erp implementation are few in number; 5- there is not one single dimension to measure erp system success.
Meta-analysis on the implementation of ERP systems
Patricio Ramírez Correa,Rosario García Cruz
JISTEM - Journal of Information Systems and Technology Management , 2005,
Abstract: This paper reports a systematic revision of scientific literature about ERP systems implementation. Based in 168 articles published in ISI journals the study makes an analysis set. First, we studied the evolution of the research on the phenomenon. Next, we distinguished according to the used research methodologies, this analysis included: in the field studies, the statistical techniques used and the studied variables; in the case studies, the design type and the study problem; and in the conceptual works its impact in literature. Additionally, we synthesized the critical success factors proposed in ERP systems implementation. Last, and with the intention of giving support to the development of future hypotheses, we given some conclusions on the scientific antecedents found in the study.In a general analysis, we concluded that the publications about ERP systems implementation present a clear tendency of growth and those are concentrated in information systems journals. The empirical studies are preferred, the case study is used most frequently, and normally the studied organizations are great multinationals of the industrial sector. On the other hand, from the revision of the articles, we concluded that, first; the size of the organization has an important role in the ERP systems implementation. Second, the factors that affect the late adoption of an ERP differ from which affects its early adoption. Third, in the implementation of the ERP there is a cultural collision. Fourth, there are few rigorous scientific studies on ERP implementation success factors. Fifth, there is not a single dimension for the ERP system success measurement
Estado de conocimiento de las diatoméas dulceacuícolas de Chile
Rivera Ramírez,Patricio;
Gayana (Concepción) , 2006, DOI: 10.4067/S0717-65382006000100002
Abstract: through 1917, foreign researches provided the only information available on the diatom flora of chile's continental waters. since 1967, research in this area has focused on three of chile's geographical areas: the central zone, the concepcion area, and the lakes region. the lack of specialized literature and the use of inadequate research techniques and instruments have led to scarce and inexact knowledge of chile's continental diatom flora; many taxa have been erroneously identified. here, the actual number of articles and taxa are indicated and the characteristics of the sole existing diatom collection are presented. finally, some steps are suggested to motivate taxonomical studies in chile.
INDICE BIBLIOGRAFICO DE LAS DIATOMEAS (BACILLARIOPHYCEAE) DE CHILE
Rivera Ramírez,Patricio;
Gayana. Botánica , 2000, DOI: 10.4067/S0717-66432000000100002
Abstract: recent revisions of families and genera of chilean diatoms reveal that the taxonomic knowledge on this flora is still limited, and in some instances, not reliable. this paper provides information about bibliographic references on taxonomy and distribution of marine and freshwater diatoms from chile and includes 197 references since 1840 to 2000
Estado de conocimiento de las diatoméas dulceacuícolas de Chile The state of knowledge of freshwater diatoms of Chile

Abstract: Hasta 1917 la información existente sobre la flora diatomológica de aguas continentales de Chile provino de las publicaciones de investigadores extranjeros. A partir de 1967 las investigaciones se concentran en tres áreas de Chile: la zona central, el área de Concepción y la Región de Los Lagos. El conocimiento actual sobre esta flora es escaso y poco exacto, pues muchos de los taxa se alados han sido erróneamente determinados. Se considera como causales de este hecho la carencia de literatura especializada y la utilización de técnicas y de instrumental de investigación inadecuados. Se indica el número de artículos y de taxa se alados para el país, y se comentan las características de la única colección diatomológica existente. Finalmente se sugieren algunos pasos para incentivar los estudios taxonómicos en Chile.

Abstract: Recientes revisiones de familias y géneros de diatomeas chilenas demuestran que el conocimiento taxonómico sobre esta flora es aún muy incompleto y, en muchas ocasiones, erróneo. El objetivo de esta obra es entregar información sobre los trabajos taxonómicos y de distribución de las diatomeas marinas y dulceacuícolas de Chile y contiene 197 referencias bibliográficas correspondientes al período 1840-2000 Recent revisions of families and genera of Chilean diatoms reveal that the taxonomic knowledge on this flora is still limited, and in some instances, not reliable. This paper provides information about bibliographic references on taxonomy and distribution of marine and freshwater diatoms from Chile and includes 197 references since 1840 to 2000

Abstract: the present work analyzes and shows the behavioral inequality of the direct state support (dss), in the area of scientific research, that the chilean government grants the universities that belong to the council of rectors of chilean universities. the economic impact of scientific publications on the dss and an economic value for each publication, called total marginal revenue (tmr) was determined. also, in order to discuss the implications of the dss model as an incentive to research activities, the following points are analyzed: (i) gini distribution index of inequality; (ii) relationship between tmr and scimago ranking; and (iii) relationship between tmr and institutional accreditation of research activities. the analyzes presented is useful to universities for the following actions: a) self control of academic units, periodically evaluating their contribution to publication impact; b) to develop university policy that incentivizes isi and scielo publications; and c) to plan programs to support research activities.
LA INCONCORDANCIA DE GéNERO Y NúMERO EN EL CONTACTO DE LENGUAS
Ramírez Cruz,Héctor;
Forma y Función , 2009,
Abstract: this article analyzes expressions with discordant grammatical structures. the corpus involves the transcription of sixty hours of recordings of personal narrations, mythological texts and other stories in spanish by about two hundred forty-three bilingual informants from colombian borderlands. analysis of the expressions is based on the type of grammatical digression (gender, number or person and number) and the type of grammatical paradigm they modify (nominal, verbal or nominal-verbal). the relevance of their classification as linguistic interference is analyzed from two theoretical perspectives: on one hand, language contact studies, in association with sociolinguistics and dialectology, and, on the other, psychology of learning, psycholinguistics and teaching of foreign languages. data are contrasted with results from language in contact between spanish and non-amerindian languages, highlighting the problems of classifying discordant grammatical structures as linguistic interference.
