Measuring Software Process: A Systematic Mapping Study

Context: Measurement is essential to reach predictable performance and high capability processes. It provides support for better understanding, evaluation, management, and control of the development process and project, as well as the resulting product. It also enables organizations to improve and predict its process’s performance, which places organizations in better positions to make appropriate decisions. Objective: This study aims to understand the measurement of the software development process, to identify studies, create a classification scheme based on the identified studies, and then to map such studies into the scheme to answer the research questions. Method: Systematic mapping is the selected research methodology for this study. Results: A total of 462 studies are included and classified into four topics with respect to their focus and into three groups based on the publishing date. Five abstractions and 64 attributes were identified, 25 methods/models and 17 contexts were distinguished. Conclusion: capability and performance were the most measured process attributes, while effort and performance were the most measured project attributes. Goal Question Metric and Capability Maturity Model Integration were the main methods and models used in the studies, whereas agile/lean development and small/medium-size enterprise were the most frequently identified research contexts.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2016-76956-C3-2- RMinisterio de Economía y Competitividad TIN2015-71938-RED

A survey on business processes management suites

Over the last decade, processes have become an important asset for daily life in organizations because an adequate Business Processes Management (BPM) of an organization (e.g. software development companies) can help achieve organizational objectives. Especially, it is important to efficiently manage these processes vital for the organizational performance in order to continually improve, therefore increasing productivity and competitiveness within the organization (e.g. software processes in software companies). This management is associated with the process lifecycle and, at present, there are many tools (Business Process Management Suites, BPMS) for managing this lifecycle. However, all BPMSs do not provide full support for this lifecycle what makes it more difficult to choose the right BPMS (according to the needs of the organization). This paper presents a survey on BPMS highlighting each phase of the process lifecycle what enables organizations to compare specific BPMS according to their own organizational objectives. This survey has been carried out using a methodology that combines systematic literature review with quality models. This methodology has been used successfully in other contexts. Finally, this paper also describes how this survey has been instantiated on specific open source BPMSs.Ministerio de Economía y competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015- 71938-RED

Early Diagnosis of Oral Cancer: A Complex Polyhedral Problem with a Difficult Solution

Oral and oropharyngeal cancers are a growing problem, accounting for 377,713 and 98,412 new cases per year all over the world and 177,757 and 48,143 deaths annually, respectively. Despite the substantial improvement in diagnostic procedures and treatment techniques in recent years, the mortality rate has not decreased substantially in the last 40 years, which is still close to 50% of cases. The major cause responsible for this high mortality is associated with the high percentage of oral cancers diagnosed in advanced stages (stages III and IV) where the treatment harbors poor efficacy, resulting in challenges, mutilations, or disability. The main reason for cancer to be diagnosed at an advanced stage is a diagnostic delay, so it is critical to reduce this delay in order to improve the prognosis of patients suffering from oral cancer. The causes of oral cancer diagnostic delay are complex and concern patients, healthcare professionals, and healthcare services. In this manuscript, oral cancer diagnostic delay is critically reviewed based on current evidence, as well as their major causes, main problems, and potential improvement strategiesResearch group CTS-392 (Plan Andaluz de Investigación, Junta de Andalucía, Spain

An association rule mining method for estimating the impact of project management policies on software quality, development time and effort

Accurate and early estimations are essential for effective decision making in software project management. Nowadays, classical estimation models are being replaced by data mining models due to their application simplicity and the rapid production of profitable results. In this work, a method for mining association rules that relate project attributes is proposed. It deals with the problem of discretizing continuous data in order to generate a manageable number of high confident association rules. The method was validated by applying it to data from a Software Project Simulator. The association model obtained allows us to estimate the influence of certain management policy factors on various software project attributes simultaneously

Climatology of new particle formation at Izaña mountain GAW observatory in the subtropical North Atlantic

A climatology of new particle formation (NPF) events at high altitude in the subtropical North Atlantic is presented. A 4-year data set (June 2008–June 2012), which includes number size distributions (10–600 nm), reactive gases (SO2, NOx, and O3), several components of solar radiation and meteorological parameters, measured at Izaña Global Atmosphere Watch (GAW) observatory (2373 m above sea level; Tenerife, Canary Islands) was analysed. NPF is associated with the transport of gaseous precursors from the boundary layer by orographic buoyant upward flows that perturb the low free troposphere during daytime. On average, 30% of the days contained an NPF event.This study was performed within the context of several projects, supported by the Ministry of Economy and Competitiveness of Spain (POLLINDUST, CGL2011-26259), REDMAAS (CGL2011- 15008-E) and GRACCIE (CSD2007-00067) and by the European Union (FP7, ACTRIS, grant contract: 262254)

Technical Tool Surveys and Comparative Studies: A Systematical Approach

Comparative studies and surveys on different technologies are common practices in research environments, not only when planning a new research line, but also in enterprise environment, for example, when a new project is going to be developed and the suitable technology must be selected. In the research context, an ordinary and formal method frequently followed to analyse the situation is the Systematic Literature Review (SLR). However, SLR is not enough, if the study is oriented towards comparing technologies or tools solutions. This paper presents a mechanism to be applied systematically in surveys and comparative studies of tools and technological solutions. It is based on general concepts defined in SLR, but it extends them in order to cover other necessities. The paper illustrates how this mechanism is applied to a real project named THOT and it offers conclusions and learned lessons from the last trends.Ministerio de Ciencia e Innovación TIN2013- 46928-C3-3-

Dysplasia in oral lichen planus: relevance, controversies and challenges. A position paper

Background: Patients with oral lichen planus (OLP) have an increased risk of oral cancer. For this reason, OLP is classified as an oral potentially malignant disorder. However, the precise personal (or individual) risk is unknown. Recent meta-analytical studies have reported that dysplastic OLP may transform to cancer in around 6% of cases, while the rate of transformation is lower (<1.5%) in non-dysplastic cases. The presence of epithelial dysplasia has emerged as the most powerful indicator for assessing cancer risk in oral potentially malignant disorders in routine practice. However, the general acceptance of epithelial dysplasia as an accompanying histologic feature in OLP is subject to great controversy. Many pathologists consider the presence of dysplasia as a criterion to exclude OLP when routinely reporting on this disease. This practice, widespread among oral pathology professionals, has resulted in the underestimation of the potential for malignancy of OLP. Material and Methods: A review of the literature was carried out in order to critically analyze the relevance, controversies and challenges encountered across the diagnosis of epithelial dysplasia in OLP. Results: 12 studies have been published examining dysplastic changes in OLP, reporting figures ranging from 0.54% to 25% of cases with dysplasia in the first diagnostic biopsy. The diagnosis of dysplasia in the OLP poses an additional difficulty due to the fact that the affected oral epithelium per se develops changes related to autoimmune aggression. Among the most frequent histological features of OLP that develops dysplasia are basal cell hyperplasia with basaloid appearance, loss of basal cells polarity, cellular and nuclear pleomorphism and irregular stratification. Conclusions: Epithelial dysplasia should not be considered an exclusion criterion for OLP; its evaluation requires experienced pathologists in this field

Factores del comportamiento del consumidor y los hábitos de consumo de los piuranos durante la pandemia COVID 19 - Año 2021

Esta investigación estableció como objetivo general el establecer la relación entre los factores del comportamiento del consumidor y los hábitos de consumo de los piuranos durante la pandemia del Covid 19 en el año 2021.El estudio fue desarrollado en circunstancias que el mundo era afectado por la emergencia sanitaria. Fue una investigación de diseño no experimental, de tipo correlacional y de corte transversal. La población para el estudio lo constituyeron la población de Piura, es decir personas entre 20 y 40 años de edad. La muestra para la investigación fue de 384 clientes, y el estudio tuvo un margen error del 5% y un 95% de nivel de confianza al procesar los datos. Se trató de un muestreo aleatorio y estratificado, y para ello se seleccionaron proporcionalmente, participantes de los tres distritos de la ciudad: Piura, Castilla y Veintiséis de octubre. La técnica de investigación seleccionada fue la encuesta y con ese fin se confeccionó un apropiado cuestionario apropiado. Los resultados indican que existe una correlación positiva baja entre las dos variables de la investigación. Dentro de los factores del comportamiento del consumidor, todos mostraron relación positiva baja con las compras impulsivas pero los factores personales son los que tuvieron una correlación menos débil con la variable dependiente.This research established as general objective to determine the relationship between the consumer behaviour factors and the consume habits of the Piura `s in the year 2021. The study was developed in circumstances when the world was affected by the sanitary emergency. It was a non experimental, correlational and a cross sectional research. The population for this study were the Piura city which were pepole from 20 to 40 years old. The sample was about 384 clients and an a 5% eroor margin and 95% confidence level when processing the data. A stratified sampling was applied and the three districts of Piura: Piura, Castilla and Ventiseis de octubre were considered in the process. A survey was chosen as technique for the research and so an appropiate quetionnaire was elaborated. The findings show that there is a positive and low relationship between both variables of the investigation. Whitin the consumer behaviour factors, all of them show to have low relationship with the consume habits but the personal factors were those who had the highest correlation with the independent variable.Tesi
