Towards a TDD maturity model through an anti-patterns framework
Agile software development has been adopted in the industry to quickly react
to business change. Since its inception both academia and industry debate the
different shades that agile processes and technical practices play in the
day-to-day of students and professional developers. Efforts have been made to
understand the pros and cons of the Test Driven Development (TDD) practice to
develop software as part of a professional environment. Despite the effort of
practitioners to list the TDD anti-patterns that unveil undesired effects in
the code when practicing TDD, work is needed to understand the causes that lead
to that. In that sense, this paper proposes a research project that explores
the TDD anti-patterns context and what leads practitioners to face them in the
software development context. As a result, we expect to offer a TDD maturity
framework to help practitioners in the process of writing code guided by tests
and prevent the addition of anti-pattern
Impact of primary care nursing workforce characteristics on the control of high-blood pressure: A multilevel analysis
Objective: To determine the impact of Primary Health
Care (PHC) nursing workforce characteristics and of
the clinical practice environment (CPE) perceived by
nurses on the control of high-blood pressure (HBP).
Design: Cross-sectional analytical study.
Setting: Administrative and clinical registries of
hypertensive patients from PHC information systems
and questionnaire from PHC nurses.
Participants: 76 797 hypertensive patients in two
health zones within the Community of Madrid, North-
West Zone (NWZ) with a higher socioeconomic
situation and South-West Zone (SWZ) with a lower
socioeconomic situation, and 442 reference nurses.
Segmented analyses by area were made due to their
different socioeconomic characteristics. Primary
outcome measure: Poor HBP control (adequate figures
below the value 140/90 mm Hg) associated with the
characteristics of the nursing workforce and selfperceived
CPE.
Results: The prevalence of poor HBP control,
estimated by an empty multilevel model, was 33.5%
(95% CI 31.5% to 35.6%). In the multilevel
multivariate regression models, the perception of a
more favourable CPE was associated with a reduction
in poor control in NWZ men and SWZ women
(OR=0.99 (95% CI 0.98 to 0.99)); the economic
immigration conditions increased poor control in NWZ
women (OR=1.53 (95% CI 1.24 to 1.89)) and in SWZ,
both men (OR=1.89 (95% CI 1.43 to 2.51)) and
women (OR=1.39 (95% CI 1.09 to 1.76)). In all four
models, increasing the annual number of patient
consultations was associated with a reduction in poor
control (NWZ women: OR=0.98 (95% CI0.98 to 0.99);
NWZ men: OR=0.98 (95% CI 0.97 to 0.99); SWZ
women: OR=0.98 (95% CI 0.97 to 0.99); SWZ men:
OR=0.99 (95% CI 0.97 to 0.99).
Conclusions: A CPE, perceived by PHC nurses as
more favourable, and more patient–nurse consultations,
contribute to better HBP control. Economic immigration
condition is a risk factor for poor HBP control. Health
policies oriented towards promoting positive
environments for nursing practice are neededThe results presented here form part of a study that has been
funded partially with the First Prize for National Research in Nursing
(12th edition) from Hospital Universitario Marqués de Valdecilla (Santander)

Discriminación percibida, autoexclusión y bienestar entre las personas con VIH en función de los síntomas de la lipodistrofia
This study examined the effects of perceived discrimination on the well-being of people with HIV and the mediating role of self-exclusion as a function of the participants' symptoms of lipodystrophy. An ex post facto study with a sample of 706 people with HIV was conducted. Self-perception of lipoatrophy and lipohypertrophy, perceived discrimination, self-exclusion and psychological well-being were measured. Results of hierarchical cluster analysis showed participants could be categorized into three groups: no lipodystrophy, mixed syndrome with predominant lipoaccumulation and lipoatrophy. Results of structural equation modeling revealed that the negative effects of perceived discrimination on well-being were mediated to a large extent by self-exclusion. Invariance analysis revealed that the mediating role of self-exclusion was not the same in the three clusters. Complete mediation of self-exclusion in the groups without lipodystrophy and with predominant lipoaccumulation was confirmed. Regarding lipoatrophy, the negative effects of perceived discrimination were greater and only partly mediated by self-exclusion. In conclusion, having lipodystrophy exposed people to more discrimination; lipoatrophy was the most stigmatizing condition. Este estudio examinó los efectos de la discriminación percibida sobre el bienestar de las personas con VIH y el papel mediador de la autoexclusión en función de los síntomas de lipodistrofia de los participantes. Se realizó un estudio ex post facto con una muestra de 706 personas con VIH. Se midió la autopercepción de lipoatrofia y lipohipertrofia, discriminación percibida, autoexclusión y bienestar psicológico. Los resultados del análisis de agrupamiento jerárquico mostraron que los participantes podían clasificarse en tres grupos: sin lipodistrofia, síndrome mixto con lipoacumulación predominante y lipoatrofia. Los resultados del modelado de ecuaciones estructurales revelaron que los efectos negativos de la discriminación percibida sobre el bienestar estaban mediados en gran medida por la autoexclusión. El análisis de invarianza reveló que el papel mediador de la autoexclusión no era el mismo en los tres grupos. Se confirmó la mediación completa de la autoexclusión en los grupos sin lipodistrofia y con lipoacumulación predominante. Con respecto a la lipoatrofia, los efectos negativos de la discriminación percibida fueron mayores y solo parcialmente mediados por la autoexclusión. En conclusión, tener lipodistrofia expone a las personas a más discriminación; la lipoatrofia fue la condición más estigmatizante.
New Evidence for the Psychometric Properties of the Spanish Version of the Gain in Alzheimer Care Instrument
The aim was to analyze the psychometric properties of the Spanish version of the Gain in Alzheimer Care
Instrument (GAIN), providing validity evidence based on its internal structure, reliability, item analysis, and relationships
with other variables. A sample of 113 informal caregivers of people with dementia completed the GAIN, along with
questionnaires assessing burden, general mental health, stress, anxiety, depression, and life satisfaction. Confirmatory
factor analysis showed a single-factor structure with adequate fit indices. Reliability of GAIN scores was satisfactory, with
McDonald’s omega equal to .91. Items yielded adequate homogeneity indices. Validity evidence based on relationships
with other variables was provided by positive correlations between GAIN scores and life satisfaction, and negative
correlations with burden, general mental health problems, stress, anxiety, and depression. All these correlations were
statistically significant, and most of them were of moderate magnitude. The Spanish version of the GAIN has a single-factor
structure and satisfactory psychometric properties. It is quick and easy to apply and given the association between GAIN
scores and other variables, it may be used to provide information about a caregiver’s psychological health status.Funding for open access charge: Universidad de Málaga
Las orientaciones de meta de los estudiantes y los deportistas: perfiles motivacionales
The main aim of this work is establish motivational profiles according to task and ego goal orientations that can be present in the subjects. Participants were 511 athletes and 574 students of secundary education. The spanish adaptation (Balaguer, Castillo & Tomás, 1996) of the Task and Ego Orientation in Sport Questionnaire (Duda, 1989) is used. In order to obtain athletes and students types and define the most important variables to discriminate between the group obtained we have carried out cluster and discriminant analysis. The results showed that there are four different profiles in function of goal orientations, and this profiles varied according to school or sport context in that subjects carried out the sport activity.ResumenEl principal objetivo de este trabajo es establecer perfiles motivacionales en función de las orientaciones de meta a la tarea y al ego, presentes en mayor o menor medida en los sujetos. Los participantes fueron 511 deportistas y 574 estudiantes de secundaria (n = 1085). Es usado el Cuestionario de Orientación al Ego y a la Tarea en el Deporte (Duda, 1989) en la versión española (Balaguer, Castillo y Tomás, 1996). Son empleados el análisis de conglomerados para establecer perfiles y el análisis discriminante para dilucidar las variables de mayor relevancia en diferenciación de los mismos. Los resultados mostraron que existen cuatro perfiles diferentes en función de las orientaciones de meta y que tales perfiles varían según el contexto, escolar o deportivo, en el que los sujetos realizan la práctica deportiva.

El cuestionario de autoconcepto físico (CAF): análisis factorial confirmatorio y predictivo sobre el rendimiento académico global y específico del área de educación física
The objetives of this study were to examine the factorial structure of the CAF (Questionnaire of Physical Autoconcept) in a different context of it´s creation as well as to verify the possible relations of his dimensions with the academic performance (global and in Physical Education) and if it would be possible to predict from those ones. The participants were 574 students of ESO from Valencian Community. There was carried out the confirmatory factorial, correlacional and path analysis. The results obtained reveal that the CAF shows suitable indexes of reliability and average discrimination, as well as a few acceptable indexes of adjustment, though, the questionnaire achieves a better adjustment and a bigger capacity of discrimination if an element of the same one is avoided. On the other hand, they find positive relations between all the dimensions of the questionnaire and the performance in Physical Education, and negative between some of the dimensions and the global performance.ResumenLos objetivos de este trabajo fueron examinar la estructura factorial del CAF (Cuestionario de Autoconcepto Físico) en un contexto distinto al de su creación así como averiguar las posibles relaciones de sus dimensiones con el rendimiento académico (global y en Educación Física) y si éste se puede predecir a partir de las mismas. Los participantes fueron 574 estudiantes de ESO de la Comunidad Valenciana. Se llevaron a cabo análisis factorial confirmatorio, correlacional y de vías. Los resultados obtenidos revelan que el CAF muestra adecuados índices de fiabilidad y de discriminación, así como unos índices de ajuste aceptables, aunque, el cuestionario logra un mejor ajuste y una mayor capacidad de discriminación media si se elimina un elemento del mismo. Por otro lado, se encuentran relaciones positivas entre todas las dimensiones del cuestionario y el rendimiento en Educación Física, y negativas entre algunas de las dimensiones y el rendimiento global.

Sistema de cifrado basado en contexto aplicado a prevención de fuga de datos
[ES] Las herramientas DLP (Data Leak Prevention) están adquiriendo un valor elevado en los últimos años debido a la importancia de proteger los datos sensibles de una organización. Muchas de las herramientas DLP se basan principalmente en la analítica de datos, ya sea un análisis de archivos almacenados o estando en tránsito por la red. La solución DLP propuesta usa el cifrado basado en contexto para evitar fugas de información. La clave de cifrado y descifrado se obtiene a partir de la ejecución de un conjunto de retos basados en el contexto de entorno y en las políticas de la empresa. En este artículo se explica la arquitectura y el diseño de la solución DLP y de los retos propuestos.Este trabajo ha sido parcialmente financiado con el apoyo del MINECO (proyecto DroneFS), con el código RTC-2015-4064-8 y del MINETUR (proyecto CiberNoid) con el código TSI-100200-2015-035.Garcia, A.; Holgado, P.; Garcia, J.; Roncero, J.; Villagrá, V.; Jalain, H.

Label-free biosensing for dry eye by Means of BICELLS
The use of Biophotonic Sensing Cells (BICELLs) based on micro-nano pattemed photonic architectures
has been recently proven as an efficient methodology for label-free biosensing by using Optical
Interrogation [1]. According to this, we have studied the different optical response for a specific
typology of BICELL, consisting of structures of SU -8. This material is biocompatible with different
types of biomolecules and can be immobilized on its sensing surface. In particular, we have measured the optical response for a biomarker in clinic diagnostic of dry eye. Although different proteins can be enstudied such as: PRDX5, ANXA 1, ANXA 11, CST 4, PLAA Y S 1 OOA6 related with ocular surface (dry eye), for this work PLAA (phospholipase A2) is studied by means of label free biosensing based on BICELLs for analyzing the performance and specificity according with means values of concentration in ROC curves
