Farrowing accommodation for organic pigs

Newborn piglets in organic farrowing pens have a lower survival rate than in conventional farrowing pens. This difference is mainly caused by housing the sow loose compared to crated and by climatic effects of the outdoor temperature. Organic lactating sows should have at least 7.5 m² indoor area with straw and a 2.5 m² outdoor run. The aim of the project was to increase piglet survival in order to improve animal welfare as well as the profitability of organic farms. In the experiment we compared survival and behaviour in 3 pen types: type 1 with outdoor run, type 2 with an indoor run and a higher proportion of solid floor and type 3 without run. Data was analysed with Analysis of Variance using parity and liveborn piglets as covariables. Results of 131 litters in total showed 9.6a, 10.8b and 9.4a (p=0.05) weaned piglets per litter for pen type 1, 2 and 3. Fouling scores indicating dunging behaviour in the indoor lying area showed 13a, 21b and 19b (p=0.04) for pen types 1, 2 and 3. We found a tendency that litters with high survival rates used the separate piglet nest sooner for lying than the litters with low survival rates. Climatic conditions seemed to be crucial for the vitality and survival of the newborn piglets. The better climatic conditions combined with the higher proportion of solid floor resulted in a higher survival rate of the piglets. These results are currently used in a second experiment focussing on extra heating around farrowing and solid floor proportion in a new farrowing accommodation

Effect of rooting area and drinker in the outdoor run on behaviour and Ascaris infection of organic pigs

Hygiene is often a problem on the outdoor runs of growing organic pigs. Manure and urine are mainly excreted outside, but spread all over the run. Reduc-ing the dirty surface may improve well being, reduce ammonia emission, improve hygiene and reduce labour and parasite infections. The presence of a rooting area and of a drinker on the outdoor run were tested in a 2x2 factorial design. The pens with the rooting areas had a higher number of pigs on the outdoor run than the pens without a rooting area (1.6 vs 1.2 pigs). This was caused by more pigs in area 2 and 3. At higher temperatures there were more pigs outside, except in the root-ing area: this was popular at all temperatures. A rooting area resulted in a cleaner outdoor area, however in some cases the root-ing area became a dunging area. An extra outdoor drinker leads to a cleaner area around the drinker, but to a dirtier indoor area. No difference in Ascaris infection was found between the four treatment combinations

Addressing the challenging elements of distance education

For this special issue, we invited submissions from all disciplines and domains to understand how innovative learning and teaching strategies, learning design approaches, and the uses of technology might enable students to fulfill authentic learning requirements and the challenging aspects of higher education in fully online modes. The response to our call was somewhat overwhelming, with abstracts submitted by practitioners from all over the world, confirming to us that there are many stories to share, both successful and less so, about new and reimagined approaches that inform innovative teaching and learning practice. There were far more ideas and cases than we could fit into this issue, so we have carefully selected the articles that serve as insightful examples and critical reflections of practice. They are also a reminder that the genie is well and truly out of the bottle, and returning to pre-COVID-19 practice will not make the most of what we have learned, nor offer the flexibility that is required for the future. This special issue provides both a glimpse into that future and a range of ideas on how to approach some of the challenges of designing for distance education

The use of outdoor runs with rooting areas and drinkers by organic pigs

Hygiene is often a problem on the outdoor runs of growing organic pigs. Manure and urine are mainly excreted outside, but spread all over the run. Reducing the dirty surface may improve well being, reduce ammonia emission, improve hygiene and re-duce labour. The presence of a rooting area and of a drinker on the outdoor run were tested in a 2x2 facto-rial design. The pens with the rooting areas had a higher number of pigs on the outdoor run than the pens without a rooting area (1.6 vs 1.2 pigs). This was caused by more pigs in area 2 and 3. At higher temperatures there were more pigs outside, except in the rooting area: this was popular at all temperatures. A rooting area resulted in a cleaner outdoor area, however in some cases the rooting area became a dunging area. An extra outdoor drinker leads to a cleaner area around the drinker, but to a dirtier in-door area

Ἰουδαίαν in Acts 2:9: a Diachronic Overview of its Conjectured Emendations

The appearance of Ἰουδαίαν in the table of nations (Acts 2:9–11) has troubled interpreters for centuries. Several scholars have proposed to emendate the text. The argumentations for such conjectures vary in elaboration and support. This article gives a diachronic overview of the conjectured emendations. It concludes with an evaluation of the discussion from a phenomenological perspective and a summary of the used argumentation, thereby providing input for a reversed engineering approach to the issue

Ἰουδαίαν in Acts 2:9:Reverse engineering textual emendations

Building on a plethora of conjectured emendations for IOÏ'ΔAIAN, this article approaches the issue once again to test the viability of a quantitative tool and to establish the possibility of palaeographical confusion of IOÏ'ΔAIAN with an alternative topo- or demonym. The article starts with an experiment using Greek topo- and demonyms derived from contemporary Christian, Jewish, and Classical sources to establish a palaeographical confusion score. Next the likeliness of the "closest"alternatives in the geographical arrangement of Acts 2:9-11 is explored. The article ends with an evaluation of the possible implications for the text in Acts 2:9 as well as a critical appraisal of the method for conjectural criticism.</p

GIS as a heuristic tool to interpret ancient historiography: A case study to reconstruct what could plausibly have happened according to the accounts in New Testament texts

This article examines how GIS can be used as a heuristic tool to reconstruct spatial–temporal events from narratives in order to examine whether a scenario is conceivable within the narrative world. The narrative about Paul's escape from Berea (Acts 17:14–15) is used as a case study. Several interpretive issues related to spatial and temporal questions surround these texts. In the case study, three methods are applied: (a) least-cost path analysis on elevation data to construct journeys and travel times for Roman roads; (b) network analysis to find seafaring routes valid for ancient times; and (c) the integration of spatial and temporal data in a space-time cube. Our main finding is that the method yields insights into the spatial–temporal dynamics of the narrative. This helps a modern reader to better understand the narrative conceivability of a story in the mind of a first-century reader.Urban Data Scienc
