After a brief historical sketch of the earlier educ'al systems salient features of the present systems are identified: (1) integration with system of the trusteeship power. In British sphere local autonomy in educ'al policy exists up to the end of the secondary Sch while the French territories are unified with that of France. (2) Degree of educ'al uniformity & methods of control: there is a universal pattern of inspection, an examination system, & defined standards for admission to higher training & employment, & control of teacher training & conditions of service. (3) Appearance of an educ'al ladder: selection for further opportunities utilizes IQ & achievement tests; & (4) universal primary schooling: compulsory educ has become a policy but adequate provision of facilities & teachers still poses problems. Though educ has exerted a powerful force for soc change there are few studies of this relationship. Educ has had a relationship to: (1) occup'al mobility, (2) urbanization, & (3) changes in Ru life: particularly affecting the status of women. Variables by which the impact of educ on soc change in Africa may be measured are suggested. D. L. Levine.

This paper describes a method for surfacing and exploring 'situated knowledge' in medium-sized organisations, with employee groups utilising a 'low impact' form of group support system (GSS), based on wireless handsets. Some results of piloting this method are summarised and one intervention is presented in detail. The method encouraged organisational members to give voice to the emotions and politics of leadership and learning in organisations, and helped to articulate how situated knowledge was ignored, as well as utilised. The method is practical, and may be used by organisations for themselves to aid the development of group as well as individual reflection, to stimulate the consideration of change.

Les auteurs ont soumis à l'étude, par résonance paramagnétique électronique et par effet Mössbauer, quelques échantillons lunaires, sous forme de roches compactes et de poussière, prélevés par Apollo 12 dans l'Océan des Tempêtes.
Ces recherches ont conduit à une importante discordance par rapport aux observations antérieures dues à Apollo 11, à savoir la très faible concentration des composés titanifères. Par contre, la contribution minime des ions ferriques et la présence probable de fer métallique, qui se déduisent de l'examen combiné par les deux méthodes en cause, sont en complet accord avec les analyses dues à la mission précédente.

A detailed study has been made by Mössbauer spectroscopy on mineralogical fractions isolated from some Apollo 12 rocks.
The resolution enhancement brought about by the mineralogical enrichment of the various fractions allows a better estimate of distribution of Fe++ ions between the different mineral phases.

The objective of this report is to provide an overview of the present StrandNet program and suggest how it might be improved to enable the StrandNet database to function as a central component of the megafauna component of the Reef 2050 Integrated Monitoring and Reporting Program (RIMReP). The report results from a cross-sectoral, expert workshop held in Brisbane on 11 June 2018 and attended by personnel from the Great Barrier Reef Marine Park Authority, Queensland government departments of Environment and Science and Agriculture and Fisheries, James Cook University and the University of Queensland, plus subsequent input from some of the workshop attendees.

Context
In Queensland, the management of estuarine crocodiles (Crocodylus porosus) by the government is important for ensuring public safety, especially along the populated east coast, where there is a large human population.

Aims
The present study aimed to determine historical, temporal and spatial patterns of human–crocodile conflict in Queensland.

Methods
The study used Queensland Government records of estuarine crocodile attacks (1971–2015), sightings by the general public (2003–2015), and removals and relocations for management purposes (1985–2015) to develop General Linear Models describing historical, temporal and spatial patterns.

Key results
The highest number of attacks, sightings, removals and relocations occurred along the populated east coast between Townsville and the Daintree during wet season months (November–February). There have been 35 crocodile attacks in Queensland since 1971 (total 0.8 per year; fatal 0.3 per year), mostly involving local people or regular visitors (77.1%), specifically adult males (71.4%; mean age 44). There has been an increase in the rate of crocodile attacks over time, with an average of 1.3 per year since 1996, most of which were non-fatal (84%). The number of crocodile sightings has been increasing annually (with a mean of 348 per year since 2011), while the number of crocodiles removed or relocated for management purposes (n = 608) has fluctuating widely each year (range 1–57).

Conclusions
The level of human–crocodile conflict in Queensland is increasing, and this is likely to be a consequence of increasing human and crocodile populations. While conflict is highest during the wet season, estuarine crocodiles pose a threat to public safety year round.

Implications
With the increase in conflict, the ongoing management of estuarine crocodiles, through targeted removals in and around areas of higher human habitation and through education, is essential for ensuring public safety into the future.
