Perceptions of School Principals on Participation in Professional Learning Communities as Job-Embedded Learning

Principal Professional Learning Communities (PPLCs) have emerged as a vehicle for professional development of principals, but there is little research on how principals experience PPLCs or how districts can support principal learning in a PPLC. This hermeneutical phenomenological study focused on perceptions of principals on participation in Professional Learning Communities as a form of job-embedded professional development for school principals. The target population for the study was elementary and middle school principals and assistant principals in a suburban district participating in an existing professional development initiative conducted by the researcher in a central office role as facilitator. The questions guiding this interpretive research were (1) How do principals describe their experience in a district-wide administrative PLC, called the Admin Council (AC PLC)?; (2) How do principals describe their experience in a Principal Professional Learning Community (PPLC), led by a central office administrator?; (3) What have principals experienced in these PLCs that is beneficial to them? Multiple interviews, observation data and meeting transcripts were analyzed to identify themes and develop a description of the lived experience of principals in a professional learning community nested within a district administrative PLC facilitated by central office. The primary results of the study are that 1) Participants described participation in PPLCs as valuable in providing connection, collegial support, collaboration, shared vision and dedicated time to focus on instructional leadership; 2) Principals experience new learning and collaborative work in PPLCs in relation to its direct relevance as something they can apply to lead change in their building contexts; 3) Principals experience a complex interior journey as part of PLC participation; and 4) Principals described having greater understanding of PLCS through participation in PLCs. Recommendations for districts include analyzing and developing structures to support common opportunities for PPLC members to enact instructional leadership. A district's alignment of leadership calendars and opportunities can support the development of joint enterprise for principals in a PPLC. Preplanned instructional leadership opportunities can ensure principals have opportunities for experiential learning as they apply new learning in their buildings. This research can support understanding of how principals experience central-office facilitated professional learning communities as job-embedded professional development.Ed.D., Educational Leadership and Management -- Drexel University, 201

Reconceptualising Personas Across Cultures: Archetypes, Stereotypes & Collective Personas in Pastoral Namibia

The paucity of projects where persona is the research foci and a lack of consensus on this artefact keep many reticent about its purpose and value. Besides crafting personas is expected to differ across cultures, which contrasts the advancements in Western theory with studies and progress in other sites. We postulate User-Created Personas reveal specific characteristics of situated contexts by allowing laypeople to design persona artefacts in their own terms. Hence analysing four persona sessions with an ethnic group in pastoral Namibia –ovaHerero– brought up a set of fundamental questions around the persona artefact regarding stereotypes, archetypes, and collective persona representations: (1) to what extent user depictions are stereotypical or archetypal? If stereotypes prime (2) to what degree are current personas a useful method to represent end-users in technology design? And, (3) how can we ultimately read accounts not conforming to mainstream individual persona descriptions but to collectives

Callose deposition and symplastic connectivity are regulated prior to lateral root emergence.

Root growth is critical for the effective exploitation of the rhizosphere and productive plant growth. Our recent work(1) showed that root architecture was dependent upon the degree of symplastic connectivity between neighboring cells during the specification of lateral root primordia and was affected by genes regulating callose deposition at plasmodesmata (PD). Here we provide additional evidence that both symplastic connectivity and callose are also important during the later phase of lateral root development: emergence. Callose immunolocalization assays indicated that transient symplastic isolation of the primordium occur immediately prior to emergence through the overlaying tissues to produce the mature lateral root.(1) Here we could corroborate these results by analyzing the mobility of a symplastic tracer and the expression of PD genes in lateral roots and in response to auxins. Moreover, we show that altering callose deposition affects the number of emerged lateral roots suggesting that PD regulation is important for emergence

Use of water troughs by wild rabbits (Oryctolagus cuniculus) in a farmland area of north–west Spain

Uso de bebederos por parte del conejo de monte (Oryctolagus cuniculus) en un paisaje agrícola en el noroeste de EspañaEn la península Ibérica, los bebederos son una herramienta de gestión de hábitat muy frecuente para incrementar las densidades de especies de caza menor, aunque el comportamiento de ingestión de agua de las especies “diana” no se ha estudiado en profundidad, como es el caso del conejo de monte (Oryctolagus cuniculus). Estudiamos el uso de bebederos por parte de conejos de monte durante 228 períodos de una semana en tres períodos consecutivos (junio–octubre) de 2008, 2009 y 2010 en un paisaje agrícola de noroeste de España, utilizando cámaras de fototrampeo. Los conejos utilizaron el 43% de los bebederos y se observó un número significativamente mayor de conejos bebiendo en bebederos rodeados por cobertura vegetal en comparación con bebederos situados en campos abiertos sin dicha cobertura vegetal. La mayoría de los conejos que bebieron fueron fotografiados de julio a septiembre (98%), si bien la utilización de bebederos no se relacionó claramente con la climatología. Los conejos bebieron principalmente durante la mañana (52% de los conejos) no tanto durante la tarde y noche, y raramente durante el mediodía. Los conejos se fotografiaron junto con perdices rojas (Alectoris rufa) en el 6% de las fotografías. Estos hallazgos sugieren que los bebederos son útiles para el conejo y otras especies con necesidades hídricas similares y que debieran ser colocados cerca de zonas con cobertura vegetal arbustiva.Installation of water troughs is a common approach to increase densities of small game species in the Iberian peninsula but little is known about the watering patterns of target species, such as the wild rabbit (Oryctolagus cuniculus). Using camera trapping, we monitored the use of water troughs by wild rabbits over 228 weeks in three consecutive periods, from June to October in 2008, 2009 and 2010, on farmland in north–west Spain. Wild rabbits used 43% of the water troughs. A significantly higher number of rabbits were observed drinking at troughs surrounded by shrub cover than at those in open fields. Most drinking events were recorded from July to September (98%), though the use of water troughs was not clearly related to weather. Wild rabbits drank mainly during the morning (52% of rabbits), less so in the evening and at night, and rarely in the afternoon. Wild rabbits were photographed together with red–legged partridges (Alectoris rufa) in 6% of photographs. These findings suggest water troughs are useful for species such as wild rabbits and should be allocated close to shrub areas.Uso de bebederos por parte del conejo de monte (Oryctolagus cuniculus) en un paisaje agrícola en el noroeste de EspañaEn la península Ibérica, los bebederos son una herramienta de gestión de hábitat muy frecuente para incrementar las densidades de especies de caza menor, aunque el comportamiento de ingestión de agua de las especies “diana” no se ha estudiado en profundidad, como es el caso del conejo de monte (Oryctolagus cuniculus).
