Lessons on Child Protection: A Survey of Newly Qualified Primary‐Level Teachers in Ireland
Authors: McGarry Kathryn , Buckley Helen 
Published: March 2013

Do all newly qualified primary‐level teachers report the same experience of child protection practices in their schools? Drawing on findings from a recent Irish study, this paper will consider the operation of official child protection guidelines in schools based on the reported awareness and knowledge of a sample of newly qualified teachers. Their knowledge of child protection guidelines pertains to experience of induction into child protection practices upon taking up employment in the school and their awareness of a designated liaison person, school child protection policy and the procedures for reporting a suspected child protection issue within the school. The findings of this research indicate that schools' compliance with national guidelines on child protection is certainly inconsistent and such anad hocapproach can be seen to impact on the perceived confidence levels of newly qualified teachers in dealing with child protection issues in the school. Given the crucial role teachers play in the safeguarding of children and the potential for strengthening this role, this paper argues for the standardisation of the operation of child protection procedures across all schools and the provision of training for all school staff. Copyright © 2013 John Wiley & Sons, Ltd.‘This paper argues for the standardisation of the operation of child protection procedures’Key Practitioner MessageThere is a clear need for enhanced, standardised pre‐service and in‐school child protection training.New entrants to the teaching profession should automatically be inducted into the school child protection policy.Schools should have clearly articulated child protection policies and action plans which are consistently communicated to staff on a regular basis.The potential for teachers to promote child welfare and protection should be acknowledged and realised.
Self‐Organization of Honeycomb‐like Porous TiO2 Films by means of the Breath‐Figure Method for Surface Modification of Titanium Implants
Authors: Li Hong , Jia Yi , Du Mingchun , Fei Jinbo , Zhao Jie , Cui Yue , Li Junbai 
Published: March 2013

AbstractThis study describes a facile breath‐figure method for the preparation of honeycomb‐like porous TiO2 films with an organometallic small‐molecule precursor. Multiple characterization techniques have been used to investigate the porous films and a mechanism for the formation process of porous TiO2 films through the breath‐figure method is proposed. The pore size of the TiO2 films could be modulated by varying the experimental parameters, such as the concentration of titanium n‐butoxide (TBT) solution, the content of cosolvent, and the air flow rate. In vitro cell‐culture experiments indicate that NIH 3T3 fibroblast cells seeded on the honeycomb‐like porous TiO2 films show good adhesion, spreading, and proliferation behaviors, which suggests that honeycomb‐like porous TiO2 films are an attractive biomaterial for surface modification of titanium and its alloys implants in tissue engineering to enhance their biocompatibility and bioactivity.
One‐Pot Synthesis of Pyrazoles through a Four‐Step Cascade Sequence
Authors: Hao Lu , Hong Jun‐Jie , Zhu Jun , Zhan Zhuang‐Ping 
Published: March 2013

AbstractA one‐pot synthesis of 3,4,5‐ and 1,3,5‐pyrazoles from tertiary propargylic alcohols and para‐tolylsulfonohydrazide has been accomplished. The pyrazoles are formed through a four‐step cascade sequence, including FeCl3‐catalyzed propargylic substitution, aza‐Meyer–Schuster rearrangement, base‐mediated 6π electrocyclization, and thermal [1,5] sigmatropic shift. In this reaction, the 3,4,5‐ and 1,3,5‐pyrazoles are produced selectively according to different substituents in the starting alcohols.

Synthesis of Bi‐doped TiO2 Nanotubes and Enhanced Photocatalytic Activity for Hydrogen Evolution from Glycerol Solution
Authors: Zhao Wenxi , Wang Xitao , Sang Huanxin , Wang Kang 
Published: March 2013

AbstractBi‐doped TiO2 nanotubes with variable Bi/Ti ratios were synthesized by hydrothermal treatment in 10 mol·L−1 NaOH (aq.) through using Bi‐doped TiO2 particles derived from conventional sol‐gel method as starting materials. The effects of Bi content on the morphology, textural properties, photo absorption and photocatalytic activity of TiO2 nanotubes were investigated. The scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray diffraction (XRD) and X‐ray photoelectron spectroscopy (XPS) observations of the obtained samples revealed the formation of titanate nanotube structure doped with Bi, which exists as a higher oxidation state than Bi3+. Bi‐doping TiO2 nanotubes exhibited an extension of light absorption into the visible region and improved photocatalytic activities for hydrogen production from a glycerol/water mixed solution as compared with pure TiO2 nanotubes. There was an optimal Bi‐doped content for the photocatalytic hydrogen production, and high content of Bi would retard the phase transition of titanate to anatase and result in morphology change from nanotube to nanobelt, which in turn decreases the photocatlytic activity for hydrogen evolution.
