The aim of the study

Acute appendicitis, one of the most frequent emergencies in general surgery, has been repeatingly investigated with regard to specific aspects such as medical history, clinical symptoms, the perioperative management and follow up.

was to investigate relevant and combined determinants for the perioperative management of acute appendicitis a systematic clinical prospective unicenter observational study was conducted. A representative patient cohort was studied (n=9,991; middle Europe) to reflect daily surgical practice through a time period of 27 years divided into 3 separate periods and the frequency of specific categories (e.g., characteristics of the medical history, clinical and intraoperative findings as well as complications), their correlation and relative risk factors for the disease as well as prognosis.

Results. 1. The wound abscess rate was 10.9%. Perforation, surgical intervention in time, acute, gangrenous and chronic appendicitis, age, accompanying diseases such as obesity, arterial hypertension, diabetes mellitus, sex, and missing pathological finding intraoperatively had a significant impact on the postoperative development of a wound abscess. 2. The longer the specific appendicitis-associated medical history was, the more frequent a perforated appendicitis occurred, greater the appendectomy (AE) rate in a non-inflamed appendix and higher the rate of required second interventions. 3. The average hospital stay was 11 days. 4. There was a significantly decreased percentage of patients with no pathological finding intraoperatively at the appendix vermiformis (p<0.001), who underwent AE, in particular, through the last investigation period from 1997 to 2000 onto only 6.8% (1974-1985, 15.5%; 1986-1996, 10.3%). 5. The mortality was 0.6%, with no significant difference comparing male and female patients (p=1), the three investigation periods (p=0.077), or the patients with AE in non-inflamed appendix (0.4%) and AE in acute appendicitis (0.6%; p=0.515). The study showed a positive, partially significant quality improvement within the presenting clinic with regard to a decreased rate of AE in non-inflamed appendix, wound abscess rate and, in particular, to mortality. Despite this, there is a trendy increase of the perforation rate in the investigated cohort.

Conclusion. Quality control remains indispensable for the assessment of the disease´s surgical treatment. A further significant improval of this control might be achieved by multicenter studies and multifactorial evaluations.

Abstract

A large number of cigarette additives was tested for the effect on the combustion temperature, including free radical initiators and inhibitors, salts of organic acids, inorganic salts and other inorganic compounds, lead-borate glasses, oxidizing agents, petroleum refining and oxidative catalysts, flame retardants, fire-proofing salts and other compounds and mixtures. Most of the additives showed no dramatic increase or decrease of temperature even at high concentrations but some indications of small alterations were obtained in a few cases.

Abstract

Jaarsma C.F., van Langevelde F., Beunen R.: Landscape ecology and rural roads: Traffic calming for improving both landscape and wildlife? Ekologia (Bratislava), Vol. 32, No. 4, p. 352-360, 2013.

The concept of traffic calming has successfully improved road safety. This concept applied in rural areas has provided new insights in the mitigation of negative effects of roads and traffic. Earlier studies have shown that the concept, distinguishing between local access roads and rural arterial highways, can also improve landscape connectivity for wildlife. Physical speed-reducing devices are frequently used in the context of traffic calming, but applying these devices may negatively impact the coherence and identity of the landscape. Therefore an alternative approach for speed reduction has been proposed, namely applying local landscape elements (such as hedgerows), plantings and objects of cultural heritage (such as railings of small bridges over local water courses) as speed-reducing devices. We explain this ‘green approach’ with examples from Dutch practice. We conclude that a combination of disciplines is needed to realize this new approach, which may be more cost-effective than the traditional approach and additionally improve the landscape quality. The new insights are at least equally effective from a landscape ecological viewpoint.

Abstract

Much has been said about elevating the HRMgt function to strategic levels. Adopting a more evidence-based approach through the use of data analytics is considered an important driver in this direction. This provides a more potent decision-making resource that enables less biased and harder evidence which ultimately is more convincing. But will Strategic HRMgt adopting data-driven strategies require people in the profession to adopt new skills? This exploratory project is work-in-progress and presents initial interview results. Interviewees report that the use of HRMgt data analytics can certainly improve the strategic value of HR and that while the use of data can drive HR decisions more convincingly, HRMgt itself cannot be reduced or substituted by data. The participants also reported that HR professionals would require learning new skills, amongst them IT, analysis and interpretation of data. The project aims to eventually draw a number of attributes or skill-sets to this effect.

Abstract

In this research we studied the correlation between the level of students’ online participation and their overall performances. We examined in this study, the participation level in different learning activities assigned to two large cohorts of learners, and compared them with their final grades at the end of the year. We defined the quality of their participation in the online course as being classified into the level of learning activities in which they participated. Learning activities were grouped into four levels which were identified namely at the knowledge, understanding, critical thinking skills and practical competencies. The findings revealed that participation in higher-order online learning activities, that is the higher ability to show critical skills and practical competencies, resulted in better grades of the learners in the module. However, the results also highlighted that overall students had a tendency to score more marks in the knowledge category as the activities required lower order cognitive skills. It was further observed that low performers demonstrated a tendency to obtain lower marks in all the four grouping levels and vice-versa for high performers. Two key elements can be concluded from the findings. The first aspect is about instructional design of such online courses where there is a need for the inclusion of learning activities targeted at the development of different types of skills, and second is the distribution and weighting given to these categories. The recommendation is that for first year students, a greater weighting of marks toward knowledge level activities will generally encourage good performances, and this could be gradually reviewed when they move on to level 2 onwards in their studies.

Abstract

We characterize the class L32 of intersection graphs of hypergraphs with rank at most 3 and multiplicity at most 2 by means of a finite list of forbidden induced subgraphs in the class of threshold graphs. We also give an O(n)-time algorithm for the recognition of graphs from L32 in the class of threshold graphs, where n is the number of vertices of a tested graph.

Abstract

When it comes to purchase decisions for fair-trade clothing, there seems to be a gap between actions and words. Only few people buy fair trade despite stating moral concerns. Based on a survey of German consumers and the results of a behavioral economic game, the article presents strategies to minimize the gap identified between the willingness to purchase and the moral standards that many consumers set for themselves. The data suggests several consumer types and provides a few promising starting points for strategies that are not based on selflessness but rather generate more tangible benefits for the individual consumer groups. At least three of five consumer types or two-thirds of the consumers may constitute possible target groups according to the findings.
