title: An Investigation of Catania's Concept of the Operant

authors: Cotton, Maree Louise

subjects: Response class

abstract: Catania (1973), in discussing the concept of the operant suggested responses should not be classified based on arbitrary criteria such as response function or topography alone, and rather should focus on the continuous distribution of responding. Catania (1973) hypothesised that response distributions would resemble a normal curve, even when reinforcement was provided for only those responses that occurred between two limits. Six domestic hens were used in a series of experiments in order to investigate Catania’s (1973) suggestion. In the first experiment the hens pecked at a flat screen with an infra-red device was mounted in front the screen to detect response location. Pecks in defined regions of the screen resulted in 3-s access to wheat. Over conditions, different quadrants of the screen were active. The whole screen remained white throughout each session except when the reinforcement was being delivered. The hens responded on a fixed-ration 5 schedule for 40 reinforcers per session. Over sessions the distribution of the locations of responses shifted to being centred over the active quadrant. Proportions of correct responses increased across sessions but incorrect responses persisted throughout. In Experiment 2 the screen was divided into ten 30-mm regions of which one was active in each condition while the whole screen remained white. The active region was moved in steps from the left to the right and from the right to the left of the screen over eleven conditions with eight sessions in each conditions and a fixed-ratio 5 schedule. In general, in each condition the proportion of correct responses increased to around 0.4. In each condition the distribution of response location shifted to being centred over the active region, resembling a normal distribution. In most cases, response rates on the active region were higher than for the inactive regions, hens usually responded on several regions at a moderate rate. In Condition 12 the active region was coloured red and this resulted in a narrower distribution of response locations, and higher proportions of correct response that other conditions for most hens. A large number of incorrect response persisted throughout this condition. These findings provide some evidence that supports Catania’s (1973) hypothetical response distributions. The argument is made that Catania’s (1973) concept of the operant could be a way to organise responses into a class and also that is provides a means of classifying response while maintaining the continuity of behaviour and, therefore, avoids the use of arbitrary criterion.

title: Western historical traditions of well-being

authors: Michalos, Alex C.

subjects: Social Science

abstract: This chapter provides a brief historical overview of Western philosophical views about well-being from the eighth century before the Common Era to the middle of the twentieth century. We explain different understandings of the concept of well-being, including our preferred understanding of well-being as the subjective states and objective conditions that make our lives go well for us. Although this review is necessarily incomplete, we discuss some of the most salient and influential contributions to our subject. To that end, we cover some key views from ancient Greece, including the aristocratic values that were considered central to leading a good life, notions of personal and more expansive harmony as they key to well-being, and the idea that the experience of pleasure is all we should really care about. We also explain some of the major religious conceptions of the good life and their progression through the Middle Ages and beyond. We further consider more recent secular conceptions of well-being, including several views on the importance of personal and public happiness. Finally, we discuss views to the effect that happiness is not enough for the good life and that we should strive for loftier goals.

title: Harakeke: Enhancing Māori Student Engagement and Achievement in a Mainstream Primary School

authors: Anderson, Diana

subjects: Harakeke

abstract: Ministry of Education research indicates that the inclusion of culture and te reo
Māori in teaching can help improve Māori student education. If students can find
the links between what is being taught and the relevance to their own lives then
information will be easier to retain. Research has also shown that environmental
education provides relevant learning that can connect students to their world.
Māori indigenous knowledge (IK) and environmental education (EE) share many
commonalities. One such similarity is the relationship between tangata (people)
and nature. While the sometimes destructive nature of this relationship has lead to
global environmental issues, this study explores the combination of IK and EE to
enhance Māori student engagement and achievement in a mainstream primary
school.
An intervention unit based on harakeke was designed delivered in a Year 5/6
boys' only class in a suburban mainstream primary school, over a 10 week period.
The environmental and socio-cultural significance of harakeke enabled a range of
kaupapa (themes) to be included in the unit. This included; eeling and how to
make and use a hinaki (eel/fish trap), karakia (prayer) and the relevance when
harvesting kai (food) and resources. Each kaupapa also provided the opportunity
for students to increase their te reo Māori vocabulary, with the introduction of
kaupapa specific words. The Māori kaupapa also enabled the students to view EE
from a Māori perspective, including the introduction of rahui - a form of
conservation.
The findings indicated that the incorporation of a Māori kaupapa strengthened
student engagement, improved student use of te reo Māori, improved the selfesteem
and confidence for some students, increased students' awareness of
harakeke and the value and versatility of the plant, and increased their awareness
from a Māori perspective on sustainable harvesting.
Bringing Māori kaupapa into the classroom allowed the classroom teacher, who
was Māori, the opportunity to share her own lived experiences of IK, as these are
passed down from generation to generation, and people are born into them. The

familiarity of whanau offered the teacher the opportunity to bring this concept into
the classroom and teach values that could flow into all curriculum areas while
strengthening relationships between the teacher and student, student and student
and teacher and student whanau.
This study has shown that both IK and EE, while each complex in their own right,
have the ability to provide a holistic curriculum approach that can lead to
engagement and achievement by Māori students in a mainstream school.
