The interface between organizational learning capability, entrepreneurial orientation, and SME growth

This paper investigates the interface between organizational learning capability, entrepreneurial orientation (EO), and small business performance. It reports on the findings from 350 small and medium enterprises (SMEs) in North Cyprus operating in the services and retailing sectors. The findings indicate a positive relationship between EO and sales and market share growth, but not between EO and employment growth. There is also a positive relationship between organizational learning capability and EO. This paper contributes to the small business management literature by providing a holistic analysis of the interface between organizational learning capability, EO, and growth.

Learning discriminative sequence models from partially labelled data for activity recognition

Recognising daily activity patterns of people from low-level sensory data is an important problem. Traditional approaches typically rely on generative models such as the hidden Markov models and training on fully labelled data. While activity data can be readily acquired from pervasive sensors, e.g. in smart environments, providing manual labels to support fully supervised learning is often expensive. In this paper, we propose a new approach based on partially-supervised training of discriminative sequence models such as the conditional random field (CRF) and the maximum entropy Markov model (MEMM). We show that the approach can reduce labelling effort, and at the same time, provides us with the flexibility and accuracy of the discriminative framework. Our experimental results in the video surveillance domain illustrate that these models can perform better than their generative counterpart (i.e. the partially hidden Markov model), even when a substantial amount of labels are unavailable.

Human activity learning and segmentation using partially hidden discriminative models

Learning and understanding the typical patterns in the daily activities and routines of people from low-level sensory data is an important problem in many application domains such as building smart environments, or providing intelligent assistance. Traditional approaches to this problem typically rely on supervised learning and generative models such as the hidden Markov models and its extensions. While activity data can be readily acquired from pervasive sensors, e.g. in smart environments, providing manual labels to support supervised training is often extremely expensive. In this paper, we propose a new approach based on semi-supervised training of partially hidden discriminative models such as the conditional random field (CRF) and the maximum entropy Markov model (MEMM). We show that these models allow us to incorporate both labeled and unlabeled data for learning, and at the same time, provide us with the flexibility and accuracy of the discriminative framework. Our experimental results in the video surveillance domain illustrate that these models can perform better than their generative counterpart, the partially hidden Markov model, even when a substantial amount of labels are unavailable.

The impact of an authentic, simulated learning activity on student preparedness for work-integrated learning

Student preparation for work-integrated learning using simulated learning experiences is an under researched field in occupational therapy. In 2013 the Deakin University occupational therapy degree introduced a simulated learning experience for students aimed at preparing them for work-integrated learning experiences. The session gave students an opportunity to practice fundamental skills of the discipline. A Likert scale survey was written and critically reviewed by the authors. Students rated the extent to which they felt that they could communicate effectively, build rapport, safely transfer clients, apply occupational health and safety principles and write case notes, prior to and after participation in the simulated learning experience. A statistically significant improvement was found for all outcomes measured. Students also reported improved confidence and valued opportunities to practice and receive feedback on skills. The results demonstrate that participation in a simulated learning activity improves confidence and skills in a range of areas that are relevant to work-integrated learning placement.

Maximising intercultural learning in short term international placements: Findings associated with orientation programs, guided reflection and immersion

Short-term international practicum experience is now a feature of many university education programs in Australia in an attempt to engage students with the growing multi-cultural aspects of Australian life. The stated purposes of such practicum experiences generally highlight intercultural learning, which is associated with the development of intercultural sensitivity, cultural identity, global citizenship and global competence. This paper tracks and documents the early and developing attitudes and dispositions of a group of pre-service teachers (PSTs) and academic staffwho were engaged with the pilot project of a pre-service placement in Malaysian secondary schools. The behaviours associated with intercultural learning are observed in association with the students' responses to changing circumstances. The paper draws attention to lessons learnt about orientation for intercultural exchanges in the development of intercultural learning and suggests ways to enhance the development of intercultural understandings and minimize cultural difference through more targeted interventions.

Learning clinical skills during bedside teaching encounters in general practice: a video-observational study with insights from activity theory

Purpose – This paper aims to explore how opportunities for learning clinical skills are negotiated within bedside teaching encounters (BTEs). Bedside teaching, within the medical workplace, is considered essential for helping students develop their clinical skills. Design/methodology/approach – An audio and/or video observational study examining seven general practice BTEs was undertaken. Additionally, audio-recorded, semi-structured interviews were conducted with participants. All data were transcribed. Data analysis comprised Framework Analysis informed by Engeström’s Cultural Historical Activity Theory. Findings – BTEs can be seen to offer many learning opportunities for clinical skills. Learning opportunities are negotiated by the participants in each BTE, with patients, doctors and students playing different roles within and across the BTEs. Tensions emerged within and between nodes and across two activity systems. Research limitations/implications – Negotiation of clinical skills learning opportunities involved shifts in the use of artefacts, roles and rules of participation, which were tacit, dynamic and changing. That learning is constituted in the activity implies that students and teachers cannot be fully prepared for BTEs due to their emergent properties. Engaging doctors, students and patients in refecting on tensions experienced and the factors that infuence judgements in BTEs may be a useful frst step in helping them better manage the roles and responsibilities therein. Originality/value – The paper makes an original contribution to the literature by highlighting the tensions inherent in BTEs and how the negotiation of roles and division of labour whilst juggling two interacting activity systems create or inhibit opportunities for clinical skills learning. This has signifcant implications for how BTEs are conceptualised.

Learning feature trajectories using Gabor Filter Bank for human activity segmentation and recognition

We describe a novel method for human activity segmentation and interpretation in surveillance applications based on Gabor filter-bank features. A complex human activity is modeled as a sequence of elementary human actions like walking, running, jogging, boxing, hand-waving etc. Since human silhouette can be modeled by a set of rectangles, the elementary human actions can be modeled as a sequence of a set of rectangles with different orientations and scales. The activity segmentation is based on Gabor filter-bank features and normalized spectral clustering. The feature trajectories of an action category are learnt from training example videos using Dynamic Time Warping. The combined segmentation and the recognition processes are very efficient as both the algorithms share the same framework and Gabor features computed for the former can be used for the later. We have also proposed a simple shadow detection technique to extract good silhouette which is necessary for good accuracy of an action recognition technique. © 2008 IEEE.

A critical analysis on "Active Learning" in the light of Cultural-Historical Activity Theory (CHAT): Implications to Physics Education and to experimental activities as a particular case.

This is a research paper in which we discuss “active learning” in the light of Cultural-Historical Activity Theory (CHAT), a powerful framework to analyze human activity, including teaching and learning process and the relations between education and wider human dimensions as politics, development, emancipation etc. This framework has its origin in Vygotsky's works in the psychology, supported by a Marxist perspective, but nowadays is a interdisciplinary field encompassing History, Anthropology, Psychology, Education for example.

Educational orientation regarding vocabulary and literacy access : Evaluating the impact of an intervention program designed to promote early learning at home

El estudio evalúa el impacto de un programa de promoción del desarrollo lingüístico y cognitivo para niños de 5 años implementado según dos modalidades: una que implicó acciones de alfabetización familiar en los hogares de los niños (modalidad intensiva) y otra que incluyó la participación de los niños en las salas de jardín de infantes (modalidad extensiva). La evaluación del impacto se realizó por medio de un diseño pre-test ? post-test. Se tomaron pruebas de vocabulario receptivo (VR), producción de categorías (PC) y escritura a una muestra de 214 niños participantes de la modalidad intensiva, 69 participantes de la modalidad extensiva y un grupo control de no participó del programa (49 niños). Los resultados mostraron que la participación en la modalidad intensiva implicó un mayor incremento en las habilidades infantiles de VR, PC que en la modalidad extensiva. A su vez ambas modalidades experimentales mostraron un mayor incremento en las variables examinadas respecto de las observadas en el grupo control. No se detectaron efectos de la escolaridad de la madre y la asistencia previa al jardín. Los resultados mostraron correlaciones significativas entre todas las variables analizadas y el valor predictivo de los puntajes en VR a principio de año respecto de los puntajes en VR y escritura a fin de año.
