Online counselling in schools as an additional option to face-to-face provision: exploration of pupils' experiences and comparison of effectiveness of working in different mediums

Aim/Purpose: A review of a UK Schools Counsellors attitudes to school-based online counselling (Hennigan & Goss, 2015) provided impetus for the current study, which sought to understand i) Pupil usage of online counselling provision (as an adjunct to f2f provision) from September 2016-July 2017 ii) Differences in CORE-10 and Goals Based outcomes for pupils using f2f only, online only or a blend of both iii) Pupil’s thoughts about offering choice of f2f, online or blended counselling. Design/Methodology: A pluralist, mixed methods approach utilised a variety of quantative analyses and a qualitative thematic analysis of post counselling interviews with pupils who had experienced either f2f or online counselling. Results/Findings: Of 68 pupils (7.6% of total pupil cohort) using the service, 52 (76%) chose to work f2f only and 16 (24%) chose online counselling (12 blended with f2f and 4 online only). Results suggest that those who received online counselling had a slightly a higher mean average first CORE-10 score and made slightly more improvement. Thematic analysis of post counselling pupil interviews revealed three main themes: ‘Convenience’, ‘Connection’ and ‘Confidentiality’. Perceived concerns that pupils had about online school-based counselling e.g. quality of relationship, confidentiality online, miscommunication and lack of visual cues, are comparable to some concerns that UK secondary school counsellors had in 2014 (Hennigan & Goss, 2015) and are potentially based upon lack of exposure to relevant information. Research Limitations: The relatively small sample size and school type selected for the study limit reliability and generalisability. Future research could address these through a larger group of participants and different types of schools. Conclusions/Implications (including practice implications): This study suggests that pupils want the convenience and flexibility of having a school-based counselling service that is both online and offline and create strong enough connections with their counsellor to make roughly equivalent progress in both mediums. Clarity around confidentiality online may encourage more pupils to access counselling this way, as well as continued exposure to what is for many, still a new and potentially risky venture

Method and apparatus for battery charge control Patent

Battery charging system with cell to cell voltage balanc

Circuit prevents overcharging of secondary cell batteries

Circuit prevents battery cell overcharging by detecting and reducing the charging voltage to the open-circuit voltage of the battery when this current falls to a predetermined value. The voltage control depends on the fact that the charging current falls significantly when the battery nears its fully charged state

Prevention of pressure build-up in electrochemical cells Patent

Preventing pressure buildup in electrochemical cells by reacting palladium oxide with evolved hydroge

Electrochemical sintering process for producing electrodes from cadmium felt and a nickel or silver grid

Electrochemical sintering process produces cadmium felt electrodes. Two pieces of cadmium felt are sandwiched around a nickel screen or silver expanded metal grid, held together by mold compression, and electrochemically sinitered by being put through several charge and discharge cycles at low current density

Enhanced secondary organic aerosol formation due to water uptake by fine particles

This study characterizes the partitioning behavior of a significant fraction of the ambient organic aerosol through simultaneous measurements of gas and particle watersoluble organic carbon (WSOC). During the summer in Atlanta, WSOC gas/particle partitioning showed a strong RH dependence that was attributed to particulate liquid water. At elevated RH levels (\u3e70%) a significant increase in WSOC partitioning to the particle phase was observed and followed the predicted water uptake by fine particles. The enhancement in particle-phase partitioning translated to increased median particle WSOC concentrations ranging from 0.3 –0.9 mgCm3 . The results provide a detailed overview of the WSOC partitioning behavior in the summertime in an urban region dominated by biogenic emissions, and indicate that secondary organic aerosol formation involving partitioning to liquid water may be a significant aerosol formation route that is generally not considered.
