Abstract

Purpose

This paper aims to examine how sample design affects the relative importance of firm and industry factors in explaining performance variations.

Design/methodology/approach

Using a sample of 14,204 Spanish firms over a 10-year time frame, this study uses partial sensitivity analysis to examine the biases in results as a consequence of three methodological relevant concerns: outliers, industry classification and period.

Findings

Results indicate that the industry effect, supported by the industrial organization theory, has been underestimated in the empirical tests.

Originality/value

This study examines the biases in results as a consequence of three methodological relevant concerns (outliers, sector classification and period), which have not been sufficiently studied to date. Moreover, the study provides some new evidence favourable to the Industrial Organization (IO) perspective, which could have been biased and underestimated by the literature, as most of the analyses do not consider the methodological issues studied in this paper.

Abstract

Purpose

The purpose of this paper is to analyze the disciplines and thematic study of scientific production in police training over the period 1988-2012.

Design/methodology/approach

Introduction and homogenization of keywords and assigning of descriptors to documents, thematic categorization of journals and, analysis of indicators of productivity and relationship of descriptors and thematic areas has been the used methodology.

Findings

Totally, 59 different descriptors of a total of 585 assigned to the 182 articles that were published in 95 journals belonging into 20 different subject areas have been identified. The most frequent descriptors are “skills,” “management development” and “violence” and the main thematic areas have been “Criminology and Penology” and “Psychology”. Totally, 47 relationships between 30 descriptors in more than two works, 35 relationships between 20 thematic areas and, 78 relationships between 43 descriptors and eight subject areas in more than two articles have been identified.

Originality/value

Characterize the disciplines and thematic of study of the articles and journals in the scientific production on police training, as well as to identify the relationships between descriptors, subject areas and among these.

Abstract

Purpose

The purpose of this paper is to identify and analyze the production and global scientific collaboration of research in police training from 1987 until 2011.

Design/methodology/approach

Selecting databases, design of search strategy, download of bibliographic records, treatment of the bibliographic information, bibliometric analysis, identification of research groups and collaborative networks of institutions and countries has been the used methodology.

Findings

Of all 1,928 papers reviewed by experts, 155 articles were related directly with police training with an average of 2.59 signatures per work, with 66.45 percent of articles signed in coauthorship. It is noted that in recent years there has been an increase in signatures and works. Articles published are distributed in journals of heterogeneous character associated to police training such as criminology, psychology, psychiatry, health or education. A significant amount of research is captained from a university scope, sometimes in collaboration with police institutions. Collaboration between members of the same institution and between institutions in the same country are predominant.

Originality/value

To characterize the scientific production of the journals, authors, institutions and countries in the area of police training, as well as to identify the collaboration networks of authors, institutions and countries within the area.

Abstract

Purpose

Most studies on Sentiment Analysis are performed in English. However, as the third most spoken language on the Internet, Sentiment Analysis for Spanish presents its challenges from a semantic and syntactic point of view. This review presents a scope of the recent advances in this area.

Design/methodology/approach

A systematic literature review on Sentiment Analysis for the Spanish language was conducted on recognized databases by the research community.

Findings

Results show classification systems through three different approaches: Lexicon based, Machine Learning based and hybrid approaches. Additionally, different linguistic resources as Lexicon or corpus explicitly developed for the Spanish language were found.

Originality/value

This study provides academics and professionals, a review of advances in Sentiment Analysis for the Spanish language. Most reviews on Sentiment Analysis are for English, and other languages such as Chinese or Arabic, but no updated reviews were found for Spanish.
