A field study using different technologies to detect calving at a large‐scale hungarian dairy farm

Morality-based interventions designed to promote academic integrity are being used by educational institutions around the world. Although many such approaches have a strong theoretical foundation and are supported by laboratory-based evidence, they often have not been subjected to rigorous empirical evaluation in real-world contexts. In a naturalistic field study ( N = 296), we evaluated a recent research-inspired classroom innovation in which students are told, just prior to taking an unproctored exam, that they are trusted to act with integrity. Four university classes were assigned to a proctored exam or one of three types of unproctored exam. Students who took unproctored exams cheated significantly more, which suggests that it may be premature to implement this approach in college classrooms. These findings point to the importance of conducting ecologically valid and well-controlled field studies that translate psychological theory into practice when introducing large-scale educational reforms.

P Removal

Research was conducted in the Manawatu region, New Zealand, to investigate the ability of Papakai tephra to remove phosphorus (P) from dairy farm mole and pipe drainage waters. The capacity of this tephra to adsorb P was quantified in the laboratory using a series of column experiments and was further evaluated in a field study. In a column experiment, the P adsorption capabilities of 2 particle size factions (0.25–1, 1–2 mm) of Papakai tephra were compared with that of an Allophanic Soil (Patua soil) known to have high P adsorption properties. The experiment used a synthetic P influent solution (12 mg P/L) and a solution residence time in the columns of c. 35 min. By the end of the experiment, the 0.25–1 mm tephra removed an estimated 2.6 mg P/g tephra at an average P removal efficiency of 86%. The 1–2 mm tephra removed 1.6 mg P/g tephra at an average removal efficiency of 58%. In comparison, the Patua soil removed 3.1 mg P/g soil at a P removal efficiency of 86%. Although, the Patua soil was sieved to 1–2 mm, this size range consisted of aggregates of finer particles, which is likely to have contributed to this material having a higher P adsorbing capacity. A field study was established on a Pallic Soil, under grazed dairy pastures, to compare drainage water P concentrations from standard mole and pipe drainage systems (control) and drainage systems incorporating Papakai tephra. The 2 tephra treatments involved filling mole channels with 1–4 mm tephra (Mole-fill treatment) or filling the trench above intercepting drainage pipes with ‘as received’ tephra (Back-fill treatment). Over an entire winter drainage season, the quantity of total P (TP) lost from the control treatment drainage system was 0.30 kg P/ha. The average TP losses for the Mole-fill and the Back-fill treatments were 45% and 47% lower than the control treatment, respectively.

Problems of this research are the difficulty of collage students to understand technique demography study material and the unavailability of appropriate teaching material. This research is aimed to increase college student understanding toward technique demography study material and study achievement. Developing material of teaching was done by: (1) Product analyzed by reducing and increasing study material; (2) Wrote material of teaching; (3) Expert validation and revised, by material of teaching expert, instructional developing, study evaluation, demography and environmental expert; (4) Small group test and revised, toward 10 collage student of geography field study; and (5) Large scale of field survey test and final product, on odd semester 2006/2007, toward 30 collage student of geography field study, FKIP, Lampung University.Pre test and post test was done in every study. The using of teaching study and doing exercise question or task in the last meeting are used in this research. The result are: (1) The increasing of college student understanding toward technique demography study material, average score in post test higher (57,76) than average score in pre test (30,42); (2) There is a significant relationship between understanding level with collage student study achievement, r-count (0,396) higher than r-table (0,361) in significant level 5% and N = 30.
