The purpose of this study is to examine the diffusion pattern of new products in Latin America, and to compare the results of principal component analysis with other descriptive approaches.

The author studies the introduction of eight new products in nine Latin American countries, analysing their diffusion rate, market potential, adoption and take-off. He performs a principal component analysis and presents a biplot. The results obtained are compared using the Mantel test.

The results indicate that the approaches used are complementary. The biplot describes 92 per cent of the explained variance. Except for a few cases, in general, the diffusion pattern in Latin America is mainly determined by cross-country wealth differences.

This study only analyses durable goods, and does not include any Central American country.

This study helps companies to predict which will be the characteristics of the diffusion pattern of other new products and to forecast their future sales.

This study helps public actors to decide how to segment the Latin American market when implementing policies that encourage the diffusion of new products.

This research extends our current knowledge on the diffusion of innovations in emerging and less developed countries. This is the first study to compare the characteristics of innovation diffusion patterns in Latin America.

El propósito de este estudio es examinar el patrón de difusión de nuevos productos en Latinoamérica, y comparar los resultados obtenidos del análisis de componentes principales con otros métodos descriptivos.

Se analiza la introducción de ocho productos nuevos en nueve países latinoamericanos. Se analizan la tasa de difusión, mercado potencial, adopción y el tiempo de despegue.

This paper aims to analyse the level of informative transparency among Spanish political parties and political foundations, according to general and descriptive information (e.g. contact, ideas and values, electoral programmes, members, etc.) and economic, governance and financial information.

The situation of the parties in each year is represented by a biplot, which is a graphical representation of a multivariate sample. The data for this analysis were obtained from the reports published by Fundación Compromiso y Transparencia (Foundation for Integrity and Transparency) for 2011 and 2012.

This paper evidences the existence of serious problems of opacity, especially in relation to financial information (balance sheet, income statement, annual accounts and audit report) and information on the fulfilment of goals and programmes (management report and compliance report).

This is the first attempt to analyse statistically the level of transparency of political parties and foundations, showing the need for a robust control system and for mechanisms to penalise conduct that limits citizens’ access to public information.

The purpose of this paper is to describe and analyse the methodology quality of the literature search protocols of systematic reviews and to assess the relevance of the search filter that applies PubMed for retrieving this type of publication of the MEDLINE database.

For the selection of the document type, a literature search about nutritional and metabolic diseases was carried out in MEDLINE and the PubMed filter was used for retrieving “Systematic Reviews”, selecting “Nutritional and Metabolic Diseases” from the Medical Subject Headings (MeSH) database as Major Topic to determine the area of knowledge. Data analysis was carried out using “External Logistic Biplot”, a novel multivariate statistical technique in the field of medical documentation.

The results highlight the large variability of the methodology used in the literature search protocols of the systematic reviews analysed and confirm the low precision of the filter used by PubMed for the recovery of systematic reviews.

The Logistic Biplot used in this research allows an optimal categorization of the different documentary typologies and classifies the documents by their methodological quality, demonstrating its usefulness for the future development of the bibliometric analysis.

Expert assessment of organized crime (OC) group capabilities is often the basis for national threat assessments; it is rare, however, for variations in collective expert opinions of OC success factors to be systematically evaluated. The purpose of this paper is to examine the differences in how 150 criminal intelligence experts from a variety of national and organizational backgrounds sort and organize perceived attributes for OC group success.

The paper uses the Royal Canadian Mounted Police (RCMP) Sleipnir framework as a foundation for a Q-sort survey regarding the characteristics of OC group success. The survey was delivered to over 150 criminal intelligence specialists at a national conference in 2011. Descriptive statistics, seemingly unrelated regression, and biplots reveal different aspects of survey responses.

Results show that perceptions of the ingredients for OC group success both vary by nationality and by analysts’ level within the hierarchy of the law enforcement structure (local, state, national). These differences are marked; particular characteristics are viewed as differentially important for the perceived success of OC groups. Furthermore, the results suggest that there are shared and structured differences in perceptions of OC group success characteristics.

The survey has identified distinct differences between the characteristics for OC group's success perceived by analysts in the USA, Canada, and beyond. Furthermore, the organizational level of the analyst (local, state, national) shapes the perceptions of success factors. It is possible variations identified merely reflect differentials in training and experience, i.e. different organizational perceptions of the same problem. That aside, the patterning of results seem likely to be based to some degree on external factors linked to OC group operations, and not just on individual characteristics of the surveyed intelligence professionals.

The current research raises a number of questions regarding the confidence that should be placed in OC group assessments. The research has highlighted areas of professional dissonance that were not apparent from the RCMP Sleipnir research alone. Causes of the dissonance in assessments, and connections of these variations to both intelligence analysts’ experience, training, and organizational ethos; and to OC group capabilities, seem deserving of additional attention.

Expert intelligence analyst interpretation of OC group capability is central to most national risk and threat assessments, yet the assessment processes themselves are rarely examined. This is a unique survey of over 150 intelligence personnel that highlights significant differences in perceptions of OC groups, differences that raise questions about how the authors evaluate the OC threat.

The purpose of this paper is to review, from a sustainable management perspective, a range of conceptual frameworks; determine the efficacy and utility of three different data sources in generating indicators collectively; and consider the utility of a single index of total ecosystem services (TESI). The ecosystem service (ES) concept has been discussed as an important model to aid sustainable land-use management.

The historical development and the relative merits of sustainable management frameworks which can be implemented in a decision-making context were examined. The efficacy of a single index TESI was examined considering three data sources for 11 contrasting sites within the UK.

The choice of conceptual framework and data source depends on the specific question and scale being addressed. Publicly available data through the Eurostat route is primarily limited to the assessment of the provisioning services.

Limitation of the study is that both bottom-up and top-down sourcing of data to conduct an ES assessment were considered.

The scale of enquiry when conducting ES assessment to aid sustainable management dictate the most useful data source. If conducting local assessments that give local data is more appropriate while conducting European Union (EU)-wide assessment gives less local precision, it does provide some insight when conducting larger-scale regional assessment which cannot otherwise be achieved.

The various data set analysed in this study all provided insight for sustainable management.

3D printing possesses certain characteristics that are beneficial for user entrepreneurship. The purpose of this paper is to investigate the business models of user entrepreneurs in the 3D printing industry. In addition, various business opportunities in 3D printing open to user entrepreneurs are classified according to their attractiveness.

The authors review the literatures on user entrepreneurship and on business models. Data from eight user entrepreneurs in Europe and North America are analyzed, applying qualitative content analysis. Multiple correspondence analysis is used to analyze their respective business models.

User entrepreneurs in the 3D printing utilize a number of different business models, which show similarities in particular business model components. User entrepreneurs focus primarily on the combination of low opportunity exploitation cost and a large number of potential customers.

Online business seems to be beneficial for user entrepreneurship in 3D printing. Policy makers can foster user entrepreneurship by expanding entrepreneurship education and lowering administrative barriers of business foundation. The results of this study are based on a small European and North American sample. Thus, they might not be applicable to other markets.

This is the first study of user entrepreneur business models in 3D printing and, thus, contributes to the literature on business models and on user entrepreneurship. In view of the novelty of the field, the business models identified in the study could serve as blueprints for prospective user entrepreneurs in 3D printing.

Many researchers have investigated the determinants of workers’ risk-taking/unsafe behaviours as a way to improve safety management and reduce accidents but there has been a general lack of research about workers’ risk information seeking behaviours or their source preferences for risk information. The purpose of this paper is to investigate whether occupational risk information source preference was risk independent (i.e. whether workers prefer to receive occupational risk information from proximal sources like supervisors and workmates regardless of the nature of the risk or the source's expertise regarding that risk, or if they discriminated between information sources based on the type of risk being considered).

Data were collected from 106 frontline construction workers who were recruited from a single building site within the UK with the help of the safety officer on site. The source from which workers preferred to receive information about a range of risks was measured using a ranking exercise. Specifically, workers were asked to rank five occupational sources (HSE, safety manager, project manager, supervisor, workmates) according to how much they preferred each one to deliver information about eight different risks (asbestos, back pain, site transport, heights, slips/trips, housekeeping, and site-specific and job-specific risks).

The paper found that supervisors and safety managers were the most preferred sources of risk information overall, but a correspondence analysis suggested that workers’ risk information source preference is risk dependent and might be driven by source expertise.

The findings have important practical implications for the role of safety managers in risk communication and for building trust within high-hazard organisations.

To the author's knowledge, this is the first study to investigate risk information source preferences in an occupational setting.

This paper aims to examine the relationship between registration of business and tax payment among micro-business owners in Nkoranza South Municipal and Nkoranza North District in Ghana.

Interview schedule was used to collect information from 720 micro business owners who qualify for tax stamps. The study used correspondence analysis as the analytical tool.

The study found a significant association between registration of business and tax payment. The biplot also indicated that unregistered businesses and businesses registered with District Assembly only are more likely to evade tax than those registered with Ghana Revenue Authority.

In Ghana, for instance, owner of business is required by law to provide information on his/her business, himself/herself and partners (as the case may be) to the Registrar-General Department, and thereafter, the business should also be registered at the nearest Ghana Revenue Authority District Office. This regulation was enacted in 2005, and it is expected that this registration will help tax authority in tax collection, as they will have adequate knowledge about businesses in the area including the location of the businesses. However, after 10 years in existence of this regulation, the effect of this registration requirement on tax payment in Ghana is not known. It is this gap that the present study seeks to fill by looking at the relationship between registration of business and tax evasion in the Ghanaian informal sector.

This paper aims to assess how a hotel geographical location in different parts of Central and Eastern Europe influences the complexity of perception of pro-environmental behavior.

To find out, whether hotel location in a specific country influences the complexity of environmental practices, this study used two closely connected multivariate statistical techniques analyzing gradients: principal components analysis and partial redundancy analysis. The research comprises data collection from seven countries in Central and Eastern Europe. In all, 25 randomly selected hotels (based on star rating) from various countries were approached to complete a questionnaire. Environmental practices were studied based on motivations, perception of barriers, perception of support from different levels of public sector, will of managers to promote pro-environmental measures based on sufficient funding, perception of legislation and perception of various other important factors.

The study reveals significant differences between hotels in Central Europe and Eastern Europe in the perception of the complexity in implementation of the environmental practices by hotel managers. The character of the present study, however, needs to address the identification of particular aspects that are relevant to the geographical differences among the studied countries.

Research was limited to a selection of Central and Eastern European (CEE) countries. There is still probability that managers in hotels from Poland and Croatia could possess different preferences. Other limitation of this study is that only special part of hotels were asked – hotels certified by star grading, out of our scope remained other hotels. It is also known that important factor is precise location of hotel within country – hotels in established tourism destination behave other way that those outside recreational areas. These factors deserve further study within this topic. There are many aspects of sustainability and environmental protection regarding hotel industry. As we have found in our principal correspondence analysis, different environmental measures were different location in biplot – some were affected by country, the other by star grading and affiliation to hotel chain. The complexity deserves to be studied in depth.

The importance lies first in the identification of the aspects that are governed by geographical differences among the countries studied. These aspects are the initiatives and support from the government and the local governments, which counteract the perception that there is a lack of financial resources and the return on investments is slow. So, based on the data, which included information from various types of hotels from seven CEE countries, the activities of national and local authorities were identified to be the main differentiating variable. The support of the environment-friendly conduct of business in the hotel industry is appreciated by hotel managers from Central Europe. On the other hand, hotel managers from Eastern Europe do not feel any significant support from either national or other public institutions. The second factor of differentiation is represented by the perception of the lack of funds. Hotel managers from Eastern Europe feel strongly about funds limitation. The coherence of both those factors is obvious in the results, as they show the same direction but opposite orientation. It has already been discussed above. When looking at the results, the authors find the perception of availability of funds to be a fundamental difference between hotel management in Central Europe and in Eastern Europe. The lack of funds is perceived more intensively in Eastern Europe than in Central Europe, particularly because of a stronger awareness of direct or indirect support for such activities by national and other public institutions in Central Europe.

The differentiation of the aspects mentioned above comes from the social and culture policies, company policies and business cultures between these two sub-realms. Pro-environmental actions are apparently promoted less publicly in Eastern European countries than in Central European countries. The reaction to the trend for demand of greener hotels is stronger in the West, and its hotels are more likely to have legislation requirements and public support as an incentive to adopt pro-environmental measures in their business operations.

The study is based on data obtained from seven countries. The results revealed a problem of the macro-environmental influence on hotels’ potential to implement environmentally sustainable approaches and procedures throughout the industry.

The purpose of this paper is to analyze the similarity of intra-indicators used in research-focused international university rankings (Academic Ranking of World Universities (ARWU), NTU, University Ranking by Academic Performance (URAP), Quacquarelli Symonds (QS) and Round University Ranking (RUR)) over years, and show the effect of similar indicators on overall rankings for 2015. The research questions addressed in this study in accordance with these purposes are as follows: At what level are the intra-indicators used in international university rankings similar? Is it possible to group intra-indicators according to their similarities? What is the effect of similar intra-indicators on overall rankings?

Indicator-based scores of all universities in five research-focused international university rankings for all years they ranked form the data set of this study for the first and second research questions. The authors used a multidimensional scaling (MDS) and cosine similarity measure to analyze similarity of indicators and to answer these two research questions. Indicator-based scores and overall ranking scores for 2015 are used as data and Spearman correlation test is applied to answer the third research question.

Results of the analyses show that the intra-indicators used in ARWU, NTU and URAP are highly similar and that they can be grouped according to their similarities. The authors also examined the effect of similar indicators on 2015 overall ranking lists for these three rankings. NTU and URAP are affected least from the omitted similar indicators, which means it is possible for these two rankings to create very similar overall ranking lists to the existing overall ranking using fewer indicators.

CWTS, Mapping Scientific Excellence, Nature Index, and SCImago Institutions Rankings (until 2015) are not included in the scope of this paper, since they do not create overall ranking lists. Likewise, Times Higher Education, CWUR and US are not included because of not presenting indicator-based scores. Required data were not accessible for QS for 2010 and 2011. Moreover, although QS ranks more than 700 universities, only first 400 universities in 2012–2015 rankings were able to be analyzed. Although QS’s and RUR’s data were analyzed in this study, it was statistically not possible to reach any conclusion for these two rankings.

The results of this study may be considered mainly by ranking bodies, policy- and decision-makers. The ranking bodies may use the results to review the indicators they use, to decide on which indicators to use in their rankings, and to question if it is necessary to continue overall rankings. Policy- and decision-makers may also benefit from the results of this study by thinking of giving up using overall ranking results as an important input in their decisions and policies.

This study is the first to use a MDS and cosine similarity measure for revealing the similarity of indicators. Ranking data is skewed that require conducting nonparametric statistical analysis; therefore, MDS is used. The study covers all ranking years and all universities in the ranking lists, and is different from the similar studies in the literature that analyze data for shorter time intervals and top-ranked universities in the ranking lists. It can be said that the similarity of intra-indicators for URAP, NTU and RUR is analyzed for the first time in this study, based on the literature review.
