From DPSIR the DAPSI(W)R(M) Emerges… a Butterfly – ‘protecting the natural stuff and delivering the human stuff’
The complexity of interactions and feedbacks between human activities and ecosystems can make the analysis of such social-ecological systems intractable. In order to provide a common means to understand and analyse the links between social and ecological process within these systems, a range of analytical frameworks have been developed and adopted. Following decades of practical experience in implementation, the Driver Pressure State Impact Response (DPSIR) conceptual framework has been adapted and re-developed to become the D(A)PSI(W)R(M). This paper describes in detail the D(A)PSI(W)R(M) and its development from the original DPSIR conceptual frame. Despite its diverse application and demonstrated utility, a number of inherent shortcomings are identified. In particular the DPSIR model family tend to be best suited to individual environmental pressures and human activities and their resulting environmental problems, having a limited focus on the supply and demand of benefits from nature. We present a derived framework, the “Butterfly”, a more holistic approach designed to expand the concept. The “Butterfly” model, moves away from the centralised accounting framework approach while more-fully incorporating the complexity of social and ecological systems, and the supply and demand of ecosystem services, which are central to human-environment interactions
A multidimensional evaluation framework for personal learning environments
Evaluating highly dynamic and heterogeneous Personal Learning Environments (PLEs) is extremely challenging. Components of PLEs are selected and configured by individual users based on their personal preferences, needs, and goals. Moreover, the systems usually evolve over time based on contextual opportunities and constraints. As such dynamic systems have no predefined configurations and user interfaces, traditional evaluation methods often fall short or are even inappropriate. Obviously, a host of factors influence the extent to which a PLE successfully supports a learner to achieve specific learning outcomes. We categorize such factors along four major dimensions: technological, organizational, psycho-pedagogical, and social. Each dimension is informed by relevant theoretical models (e.g., Information System Success Model, Community of Practice, self-regulated learning) and subsumes a set of metrics that can be assessed with a range of approaches. Among others, usability and user experience play an indispensable role in acceptance and diffusion of the innovative technologies exemplified by PLEs. Traditional quantitative and qualitative methods such as questionnaire and interview should be deployed alongside emergent ones such as learning analytics (e.g., context-aware metadata) and narrative-based methods. Crucial for maximal validity of the evaluation is the triangulation of empirical findings with multi-perspective (end-users, developers, and researchers), mixed-method (qualitative, quantitative) data sources. The framework utilizes a cyclic process to integrate findings across cases with a cross-case analysis in order to gain deeper insights into the intriguing questions of how and why PLEs work

“Early Rupture of Membranes” during Induced Labor as a Risk Factor for Cesarean Delivery in Term Nulliparas
OBJECTIVE: To determine if "early rupture of membranes" (early ROM) during induction of labor is associated with an increased risk of cesarean section in term nulliparas. STUDY DESIGN: The rate of cesarean section and the timing of ROM during the course of labor were examined in term singleton nulliparas whose labor was induced. Cases were divided into 2 groups according the timing of ROM: 1)"early ROM", defined as ROM at a cervical dilatation<4 cm during labor; and 2) "late ROM", ROM at a cervical dilatation≥4 cm during labor. Nonparametric techniques were used for statistical analysis. RESULTS: 1) In a total of 500 cases of study population, "early ROM" occurred in 43% and the overall cesarean section rate was 15.8%; 2) patients with "early ROM" had a higher rate of cesarean section and cesarean section due to failure to progress than did those with "late ROM" (overall cesarean section rate: 24%[51/215] vs. 10%[28/285], p<0.01; cesarean section rate due to failure to progress: 18%[38/215] vs. 8%[22/285], p<0.01 for each) and this difference remained significant after adjusting for confounding variables. CONCLUSION: "Early ROM" during the course of induced labor is a risk factor for cesarean section in term singleton nulliparas
The needs of foster children and how to satisfy them:A systematic review of the literature
Family foster care deeply influences the needs of children and how these are satisfied. To increase our knowledge of foster children’s needs and how these are conceptualized, this paper presents a systematic literature review. Sixty- four empirical articles from six databases were reviewed and categorized (inter-rater agreement K = .78) into four categories: medical, belongingness, psychological and self-actualization needs. The results give a complete overview of needs that are specific to foster children, and what can be implemented to satisfy these needs. This study shows psychological needs are studied more often compared to the other categories, which specially relates to much attention for mental health problems. Furthermore, most articles focus on how to satisfy the needs of foster children and provide no definition or concrete conceptualization of needs. Strikingly, many articles focus on children’s problems instead of their needs, and some even use these terms interchangeably. This review illustrates that future research should employ a proper conceptualization of needs, which could also initiate a shift in thinking about needs instead of problems
Training in crisis communication and volcanic eruption forecasting:Design and evaluation of an authentic role-play simulation
We present an interactive, immersive, authentic role-play simulation designed to teach tertiary geoscience students
in New Zealand to forecast and mitigate a volcanic crisis. Half of the participating group (i.e., the Geoscience Team)
focuses on interpreting real volcano monitoring data (e.g., seismographs, gas output etc.) while the other half of the
group (i.e., the Emergency Management Team) forecasts and manages likely impacts, and communicates emergency
response decisions and advice to local communities. These authentic learning experiences were aimed at enhancing
upper-year undergraduate students’ transferable and geologic reasoning skills. An important goal of the simulation was
specifically to improve students’ science communication through interdisciplinary team discussions, jointly prepared,
and delivered media releases, and real-time, high-pressure, press conferences.
By playing roles, students experienced the specific responsibilities of a professional within authentic organisational
structures. A qualitative, design-based educational research study was carried out to assess the overall student experience
and self-reported learning of skills. A pilot and four subsequent iterations were investigated.
Results from this study indicate that students found these role-plays to be a highly challenging and engaging learning
experience and reported improved skills. Data from classroom observations and interviews indicate that the students
valued the authenticity and challenging nature of the role-play although personal experiences and team dynamics
(within, and between the teams) varied depending on the students’ background, preparedness, and personality.
During early iterations, observation and interviews from students and instructors indicate that some of the goals of the
simulation were not fully achieved due to: A) lack of preparedness, B) insufficient time to respond appropriately, C)
appropriateness of roles and team structure, and D) poor communication skills. Small modifications to the design of
Iterations 3 and 4 showed an overall improvement in the students’ skills and goals being reached.
A communication skills instrument (SPCC) was used to measure self-reported pre- and post- communication competence
in the last two iterations. Results showed that this instrument recorded positive shifts in all categories of self-perceived
abilities, the largest shifts seen in students who participated in press conferences. Future research will be aimed
at adapting this curricula to new volcanic and earthquake scenarios
