Pedagogical Coordination in Secondary Schools from a Distributed Perspective. Adaptation of the Distributed Leadership Inventory (DLI) in the Spanish Context
Introduction: Leadership as the second factor in school improvement needs potential
leaders to be effective. Method: The present study aimed to know the potential capacity of leaders in
Spanish secondary schools through the adaptation of the DLI questionnaire to Spanish. To accurately
adapt this questionnaire, the present research group conducted content validity processes in 2017,
using the Delphi Method, in which eight experts from the Spanish Network for Research into
Leadership and Academic Improvement were invited to participate (RILME). As part of a pilot test,
preliminary tools were administered to 547 participants from secondary schools in Granada and
Jaén (Spain). Results: The present study reports on the adaptation of the DLI instrument within the
Spanish context. Acceptably high values were obtained in the analysis of reliability and internal
consistency, suggesting that this item can be reliably utilised for the exploration of the dynamics
of internal functioning in secondary education and the evaluation of the distribution of leadership
characteristics. Conclusions: The pilot study highlights how heads of studies and department heads
are potential leaders, making it easier to set up and sustain educational projects in schools.Spanish Government

Las dificultades sufridas por una mujer para llegar a ser biomatemática : Nancy Kopell
Tras haber superado una serie de dificultades de diversos tipos, entre
ellas de género, de carácter y de enfermedad, la norteamericana Nancy
Kopell ha llegado a ser una de la biomatemáticas más reconocidas en
la actualidad por sus excelentes contribuciones en el avance de la
neurociencia, al estudiar a partir de los sistemas dinámicos las redes
neuronales que gobiernan las actividades motoras rítmicas. En esta
comunicación se comentan algunas de esas dificultades que ella fue
paulatinamente venciendo y el modo en el que lo hizo. Entre ellas, la
oposición de su familia a que estudiara, debido a las ideas
conservadoras del entorno, el difícil acceso de la mujer a la
universidad en aquel tiempo, la poca credibilidad de sus posibilidades
por ser mujer y joven, etc, que al principio la hicieron sentirse insegura
e inferior a los que la rodeaban, ocasionándole incluso una fuerte
depresión. Todas estas trabas, sin embargo, una vez vencidas, la
hicieron tan fuerte que ella misma, años después, llegó a señalar que
hasta le habían venido bien, ya que el hecho de ser mujer hizo que
recayese en ella una mayor atención por parte de los demás, lo cual
incluso llegó a serle beneficioso en ciertos momentos de su vida
Interpersonal perceptions of adverse peer experiences in first-grade students
Aim: The aim of this study was to identify which adverse peer experiences better predict perceived negative peer relationships among elementary school first graders according to sex. The peer experiences examined were peer rejection, peer victimization, and mutual antipathy; the interpersonal perceptions studied were perceived peer victimization, dyadic meta-perception of peer disliking, and loneliness.
Methods: The participants were 809 children (Mage = 6.4 years, SD = 0.32; ngirls = 412, 50.9%) enrolled in 35 first-grade classes from 15 schools in 4 Spanish regions: Valencia, n = 276, 34.1%; Balearic Islands, n = 140, 17.3%; Andalusia, n = 199, 24.6%; Castile-Leon, n = 194, 24%. We calculated sex differences in peer experiences and interpersonal perceptions by means of one-way ANOVA for means differences and Fisher’s r-to-z transformation for correlations differences. We used a multilevel regression analysis (nesting variables: class and region) to determine whether the associations between each peer experiences and each perception were unique.
Results: Each adverse peer relationship predicted each interpersonal perception differentially. Peer victimization was a good predictor of the three interpersonal perceptions, and the only predictor of perceived peer victimization. Peer rejection predicted loneliness, whereas mutual antipathies predicted dyadic meta-perception of peer disliking, although more so among girls. A significant effect at region level was found but not at class level.
Conclusion: Our findings suggest that research should take into account the different levels of the social peer system when analyzing peer experiences within the classroom context. The study contributes to sensitize teachers about the greater responsiveness of 6-year-old girls to adverse peer experiences, and it could be useful for designing interventions that would help children oppose rejection and empower active bystanders to fight against peer mistreatment.Ministerio de Economía y Competitividad de España EDU2012-35930Universitat Jaume I P1-1A2012-0
Effective leadership of the leadership from the perspective of the rest of the faculty
El ejercicio del liderazgo escolar, a lo largo de la historia de España, ha
estado marcado por la escasez de candidatos y por el desempeño de un liderazgo
burocrático, basado fundamentalmente en la gestión administrativa del Centro. En
la actualidad se requiere de otra modalidad de liderazgo, no sólo por los grandes
cambios que ha habido en nuestra sociedad, sino más bien porque las funciones de
los equipos directivos han ido evolucionando según las necesidades de los centros
escolares. Para que esta función se ejerza con más eficiencia, y cómo no, también
con más eficacia, se requieren unas cualidades profesionales y personales para
cumplir dicha misión. Un equipo directivo eficaz será quien, en su conducta y en sus
relaciones interpersonales, refleje un verdadero compromiso con quienes les
acompañan en sus quehaceres diarios y, también, hacia dónde enfocan el desarrollo
de su liderazgo, es decir, el rumbo que le marcan a la institución escolar que dirigenThe exercise of school leadership, throughout the history of Spain, has been
marked by the shortage of candidates and by the performance of a bureaucratic
leadership, based fundamentally on the administrative management of the school.
Nowadays, another type of leadership is required, not only because of
their daily chores and, also, where they focus the development of their leadership, that is, the direction that they mark to the school they lea
School Principals in Spain: Interplay of Leaders, Teachers and Context
This paper analyzes the Spanish school principal figures and their future patterns of
leadership and development, according to educational policies in Europe. The first part presents
a comprehensive overview of the situation of school principals in Spain, according to the Spanish
policy; in the second part, its real practice in a secondary school is evidenced based on the results
of a conducted research. The tensions and dilemmas currently faced by school principals in Spain
will be analyzed: pedagogical leadership versus management-oriented principals. The interviews
carried out reveal the meaning that the different agents give to “leadership”. A climate of trust and
collaboration has been established between the management team, middle leaders and teaching staff,
necessary conditions for the development of a shared school project and ensure its sustainability for
achieve school improvement.This research was funded by Ministry of Education, grant number FPU2014/05050
Gender-based differences in the high-risk sexual behaviours of young people aged 15-29 in Melilla (Spain): a cross-sectional study
Background:
Research confirms the existence of gender-based differences regarding the high-risk sexual behaviour (non-use of condoms and casual partners) of young men and women. The objectives were to provide evidence for this association; to analyse the reasons why both sexes have sexual relations with casual partners and to ascertain the motives for condom use or non-use during casual sex.
Methods:
A cross-sectional study was performed on a sample of 900 participants, 524 males and 376 females. All participants were 15-29 (20.93 ± 4.071) years of age and came from four different centres (a university, two secondary schools, and a military base) in Melilla (Spain). The participants were given a socio-demographic survey as well as a psychometric text on high-risk sexual behaviour.
Results:
The results found gender-based significant differences for sexual relations with penetration (p = 0.001), number of sexual partners (p = 0.001), and sexual relations with casual partners (p = 0.001). In all of these variables, male participants had higher percentages than female participants. Reasons for having casual sexual relations were also different for men and women, differences were found for the items, opportunity (p = 0.001), interest in knowing the other person (p = 0.015), physical excitement (p = 0.056) and drug consumption (p = 0.059). Regarding the reasons for consistent condom use with casual partners, there were differences for the item, my demand of a condom (p = 0.002). For the non-use of condoms with casual partners, differences were found for the items, I do not like to use condoms (p = 0.001) and condoms lessen sensitivity and reduce pleasure (p = 0.009).
Conclusions:
Men and women were found to have different high-risk sexual behaviours and practices. Of the motives for having sexual relations with casual partners, male participants considered opportunity and interest in knowing the other person to be more important than the female participants. Regarding condom use, the female participants’ demand to use a condom was a significant gender-based difference. In contrast to the young women, the male participants mostly justified not using a condom because it lessened sensitivity and reduced pleasure
Educational Leadership Training, the Construction of Learning Communities. A Systematic Review
Instructional leadership notions and practices allow educators to engage in relevant roles
within schools. Instead of implementing these concepts in professional programs, Mexican and
Spanish education systems still preserve a “technically oriented” training model that separates
educational and professional aims. Diverse studies have identified the benefits of implementing
instructional leadership orientations within “Educational cooperation”, “Cooperative education”,
“Team teaching” and “Teacher leadership” at schools. This systematic review conducted usingWeb
of Science—contributes by organizing the produced knowledge and identifies the main findings
reported by the academic literature on this topic. It seeks to answer the following questions: (1) What
are the contributions of this research to the education systems examined? (2) What kind of knowledge
about educational leadership and professional learning communities can be inferred from them?
Results from the majority of studies found that instructional leadership offers a useful tool to
promote shared responsibility between teachers and head teachers and supports professional learning
communities. A main conclusions of the present study is that it highlights the importance of bypassing
existing bureaucratic practices within schools in order to replace the traditional “technical orientation”
of training programs. Instructional leadership may facilitate some of the required transformations in
the context of global educational reform
Desarrollo de embriones somáticos de alcornoque en biorreactores de inmersión temporal.
El sistema de inmersión temporal (SIT) se basa en el empleo de medio líquido y el establecimiento de ciclos de aporte y retirada del medio. Esto permite aprovechar las ventajas del medio líquido (favorece la absorción de nutrientes, el crecimiento del material vegetal y la dilución de los metabolitos excretados), al tiempo que reduce sus inconvenientes (suprime el contacto continuo de los explantos con el medio de cultivo, evitando los problemas de asfixia y vitrificación). Por otra parte el SIT facilita el control y el estudio de la nutrición en el cultivo in vitro y puede contribuir al desarrollo óptimo de los explantos. En este trabajo presentamos la puesta a punto de un SIT aplicado a la obtención de embriones somáticos de albaricoque
