Research note: Promoting intercultural education through art education

Taking UNESCO’s proposal ‘learning how to live together’ as a starting point, we examined to what extent visual education can be used as a tool to promote the aims of intercultural education. We analyzed the power of using artistic images from different cultures to change students’ perception of cultural differences, thereby facilitating the development of attitudes of respect towards different ethnic/cultural groups. We also investigated to what extent this strategy could contribute to the integration of minority peers into a majority group. Students were assigned to either an experimental or a control group. The experimental treatment consisted of exposing students to several art object images associated with different cultures. Our measurement instrument was based on an adapted version of the ‘Draw‐A‐Person‐Test’, which we have called the ‘Draw‐Two‐Persons‐Test’. We also used a questionnaire to examine attitudes among subjects     

Assessing overweight, obesity, diet, and physical activity in college students

The authors surveyed 738 college students aged 18 to 27 years to assess overweight, obesity, dietary habits, and physical activity. They used BMI (body mass index) > or = 25 kg/m2 or BMI > or = 85th percentile and BMI > or = 30 kg/m2 or BMI > or = 95th percentile to estimate overweight and obesity in those aged < or = 19 years. To define overweight and obesity in those > or = 20 years, they used BMI > or = 25 kg/m2 and > or = 30 kg/m2. They found overweight rates of 21.6% using BMI directly and 16.2% using BMI percentile and obesity rates of 4.9% using BMI directly and 4.2% using BMI percentile. More than 69% of the participants reported < 5 servings of fruits and vegetables per day and more than 67% reported < 20 g of fiber per day; participants reported physical activity on fewer than 3 d/wk. Most college students are not meeting dietary and physical activity guidelines, suggesting the need for prevention interventions and increased understanding of overweight in college students.     

Effectiveness of a training program for ECT nurses

Electroconvulsive therapy (ECT) is a highly technical procedure requiring a team that consists of an anesthetist, a psychiatrist, a clinical nurse specialist, and recovery nurses. Traditionally, nursing education and training in the context of providing a safe and high standard of care has not been addressed. Ninety-two nurses from 42 different health agencies participated in a training program focusing on defibrillation, electrocardiogram (ECG) and electroencephalogram (EEG) monitoring, intubation, stimulus dosing, setting up the ECT equipment, and caring for the patient. A non-experimental, one-group, pretest-posttest research design was used in this study to evaluate the effectiveness of the training program for nurses working with ECT. Effective training for nurses was hypothesized to make a difference in the standards of practice and clinical effectiveness for patients undergoing ECT. Findings from this study indicated a major knowledge deficit in key components of ECT among nurses who have responsibilities in this area of nursing care. With effective training, nurses' confidence levels increased related to setting up the equipment, administering a double dose, helping with intubation, and using a defibrillator. If nurses are to effectively function as team members in the ECT procedure, they must receive the training necessary to prepare them for this important role. The results of this study support the recommendation of the Royal Australian and New Zealand College of Psychiatrists that ECT nurses should be appropriately trained in anaesthetic and resuscitation techniques and modern ECT practice.     

Birthmothers and Subsequent Children: The Role of Personality Traits and Attachment History

Fifty-five women who had surrendered their first child for adoption and went on to have subsequent children, and 32 women who had surrendered their first child for adoption and did not have more children were given the Revised NEO Personality Inventory (NEO-PI-R) and the Attachment History Questionnaire. Women who had more children scored significantly higher on the Extroversion scale of the NEO-PI-R. Women who did not have more children were more apt to never marry and, when there was marriage, more apt to divorce. Women who had more children reported more pressure from family to relinquish their child. Attachment History Questionnaire results showed women who did not have more children reported Friends as significant support figures more often than women who did have more children.     

Inventory placement problems in dynamic supply chains

Summary  In this paper a basic model for analyzing the inventory placement problem in a supply chain is developed. The problem will be studied for a capacitated, multi-stage supply chain facing a continuous, stochastic demand for a single period for a single product — a specialty item with a very short selling season. The objective is to maximize the probability of achieving a set profit level. We prove that finding an optimal stock investment at the stages entails solving a mixed binary integer linear program. We characterize properties of the stock investment, examine two interesting cases where the stock investments have a simple structure, and develop a branch and bound approach for solving the more general case.

Zusammenfassung  In diesem Beitrag wird ein Grundmodell entwickelt, um das Problem der Lagerplatzierung in einer Lieferkette analysieren zu k?nnen. Das Problem wird für eine kapazitierte mehrstufige Lieferkette untersucht, wobei unterstellt wird, dass es um die Nachfrage nach einem einzigen Produkt für eine einzige Periode (einen Sonderartikel mit sehr kurzer Verkaufszeit) geht und diese Nachfrage stetig und stochastisch ist. Unter diesen Bedingungen soll die Wahrscheinlichkeit maximiert werden, ein vorgegebenes Gewinnniveau zu erreichen. Die Suche nach der optimalen Vorratsinvestition auf den Stufen der Lieferkette führt zur Formulierung eines gemischten ganzzahligen linearen Programmierungsproblems mit Bin?rvariablen. Die Eigenschaften der Bevorratungsinvestition werden charakterisiert, zwei interessante F?lle mit einer einfachen Struktur der Bevorratungsinvestition untersucht und ein Branch-and-Bound-Ansatz zur L?sung eines allgemeineren Problemfalls entwickelt.

     

A Bayesian Analysis of Synchronous Distance Learning versus Matched Traditional Control in Graduate Biostatistics Courses

Distance learning can be useful for bridging geographical barriers to education in rural settings. However, empirical evidence on the equivalence of distance education and traditional face-to-face (F2F) instruction in statistics and biostatistics is mixed. Despite the difficulty in randomization, we minimized intra-instructor variation between F2F and online sections in seven graduate-level biostatistics service courses in a synchronous (live, real time) fashion; that is, for each course taught in a traditional F2F setting, a separate set of students were taught simultaneously via online learning technology, allowing for two-way interaction between instructor and students. Our primary objective was to compare student performance in the two courses that use these two teaching modes. We used a Bayesian hierarchical model to test equivalence of modes. The frequentist mixed model approach was also conducted for reference. The results of Bayesian and frequentist methods agree and suggest a difference of less than 1% in average final grades. Finally, we discuss barriers to instruction and learning using the applied online teaching technology.     

Efficient designs for Bayesian networks with sub-tree bounds

We present upper and lower bounds for information measures, and use these to find the optimal design of experiments for Bayesian networks. The bounds are inspired by properties of the junction tree algorithm, which is commonly used for calculating conditional probabilities in graphical models like Bayesian networks. We demonstrate methods for iteratively improving the upper and lower bounds until they are sufficiently tight. We illustrate properties of the algorithm by tutorial examples in the case where we want to ensure optimality and for the case where the goal is an approximate solution with a guarantee. We further use the bounds to accelerate established algorithms for constructing useful designs. An example with petroleum fields in the North Sea is studied, where the design problem is related to exploration drilling campaigns. All of our examples consider binary random variables, but the theory can also be applied to other discrete or continuous distributions.     

Coparenting in Stepfamilies: A Cluster Analysis

The aim of this study was to identify types of coparenting in stepfamilies based on observational data and to examine whether these types differed regarding marital satisfaction and child adjustment. Forty-five couples attended two videotaped discussion tasks on topics of agreement and disagreement regarding coparenting issues. An exploratory cluster analysis identified three main types of coparenting in stepfamilies: (1) Cooperative coparenting (n = 19), (2) Complementing coparenting (n = 16), and (3) Conflictual coparenting (n = 10). The Complementing coparenting type appeared as a new type of coparenting that had not been described in earlier studies and that might be specific to coparenting between non-biological parents. Comparison between the three clusters showed no differences for marital satisfaction and child adjustment. Each cluster is illustrated by a family case to provide a better understanding of coparenting dynamics in stepfamilies.
