Forskning i peerfeedback har primært fokuseret på peerfeedbacks potentiale for at bidrage til studerendes læreprocesser og udvikling af akademiske færdigheder. I denne artikel undersøger vi, med afsæt i et peerfeedbackforløb for bachelorstuderende på første år, hvorfor nogle studerende vælger ikke at deltage i peerfeedback. På baggrund af fokusgruppeinterviews og skriftlige studenterevalueringer undersøger vi gennem et positioneringsperspektiv de studerendes implicitte antagelser om peerfeedback og opstiller fire diskursive positioner for ikke-deltagelse: investorpositionen, den blinde position, den bedømmelsesorienterede position og den sårbare position. De analytiske fund viser både spændinger mellem forventninger til peerfeedbackforløb studerende imellem og spændinger mellem studerendes og universitetets antagelser om peerfeedbacks læringspotentiale. I diskussionen af, hvordan vores fund bidrager til eksisterende viden, introducerer og diskuterer vi begrebet "den implicitte underviser", der bruges til at indfange de studerendes implicitte antagelser om, hvad en universitetsunderviser er og bør være.
Dansk universitetspædagogisk forskning - i videnskabelige artikler i DUT
Authors: Rienecker Lotte 
Published: May 2024

Abstract
Hvad skal Dansk Universitetspædagogisk Tidsskrifts artikler indeholde? I en artikel i Dansk Pædagogisk Tidsskrift retter to universitetspædagogiske forskere, Laura Louise Sarauw og Eva Bendix Petersen, en kritik mod DUTs videnskabelige artikler for at savne videnskabsteoretiske overvejelser, diskussion med universitetspædagogiske begreber, teorier og metoder, og feltopbygning gennem mere dialog med tekster i feltet.
Men er det så oplagt, at Dansk Universitetspædagogisk Tidsskrift har til opgave at bringe mere videnskabsteoretisk stof, teoridiskussion og teoriopbygning?
For det første er universitetspædagogiske forskere et mindretal blandt DUT’s artikelforfattere, ifølge en forfatteroptælling jeg har foretaget. En stor forfattergruppe er forskere på tværs af fag og fakulteter. For det andet er (videnskabs)teoretisk fokus ikke blandt tidsskriftets formulerede formål. For det tredje er DUT ikke et udtryk for al dansk universitetspædagogisk forskning, men kun en delmængde af den. Og endelig er det de mere anvendelsesorienterede videnskabelige, og især faglige artikler som skaber mest trafik på tidsskriftets sider.

Authors: Bagaipo Elvie Mae Cañizares , Napiere Miguela B. 
Published: May 2024

Aims: Compliance with program guidelines can pave the way for positive changes in people's lives. This study examined the influence of the characteristics of the 4Ps program beneficiaries and their compliance with program conditions and their living conditions.
Study Design: Descriptive – Correlational Quantitative Study
Place and Duration of Study: This study was conducted in a local Community in the Province of Agusan del Norte, Region Caraga, Philippines.
Methodology: This study employed the descriptive-correlational research design. Program Compliance refers to the participants’ faithful observance to the program conditions specifically on the health and education components such as the vaccination of children, natal care for pregnant mothers; and regular attendance (at least 85% in a month) of children 5-18 years old. Living Conditions refers to the education, occupation, and income status that program participants achieved while receiving and utilizing the cash grants given by the program. These constructs were measured through indicators that are contained in a researcher-made questionnaire, such as the study by Salva et al. (2023) and the Social Welfare and Development Indicators (SWDI) Booklet. The 370 out of 4,378 participants were chosen among the 4Ps beneficiaries in a local community in the Province of Agusan del Norte, who were selected through systematic random sampling. The data gathered for this study were tallied, statistically treated, analyzed, and interpreted. The statistical tools used to organize the data were descriptive statistics and multiple regression.
Results: Results show that 51.4 % of the participants belong to a family size of 5 members and below; 31.9 % are high school graduates; and 58.9 % earn an income ranging from Php 1,000.00- Php 5,000.00 monthly. Health outcomes is generally high (M=4.0); and Educational outcome is generally very high (M=4.79). All the components of the Living Condition are generally high, specifically the Health and Nutrition Component (M=4.24); Education (M=4.36) and Financial Management (4.21). Regression analysis reveal that the whole model is significant (F= 22.77, p = .000), with compliance as specifically having a significant influence on the participants’ living conditions, rejecting the null hypothesis.
Conclusion: Compliance to the program contributes to better living conditions.

The experiment was conducted at farmers field in Haridwar district of Uttarakhand during 2019-20 and 2020-21. The experiment consisted of eleven treatments viz. control (T1), 100 % RDF (T2), FYM @ 10 t/ha (T3), VC @ 5t/ha (T4), 75 % RDF + FYM @ 10t/ha (T5), 75 % RDF + VC @ 5 t/ha (T6), 50 % RDF + FYM @ 10 t/ha (T7), 50 % RDF + VC @ 5 t/ha (T8), 50 % RDF + FYM @ 10 t/ha + VC @ 5t/ha (T9), 75 % RDF + FYM @ 10 t/ha+ Azotobacter + PSB (T10), 75 % RDF + VC @ 5 t/ha+ Azotobacter + PSB (T11). The treatments were replicated thrice and were laid out in randomized block design (RBD). Wheat variety used for the experimentation was PBW 343. The net plot size was 5 m X 5 m and crop spacing was 20cm between rows. The results reported that wheat crop with the application of 75 % RDF + VC @ 5 t/ha+ Azotobacter + PSB (T11) performed better in terms of growth parameters and yield under field condition compared to some of the treatments. Significantly higher B: C (2.9) ratio was calculated for 75 % RDF + FYM @ 10 t/ha+ Azotobacter + PSB (T11). Percent increase of 5.5 % and 3.6 % was recorded during 2019-20 and 2020-21, respectively in grain yield with the application of 75 % RDF + VC @ 5 t/ha+ Azotobacter + PSB (T11) over 100 % RDF (T2). Maximum net returns were estimated in treatment T10 (75 % RDF + FYM @ 10 t/ha+ Azotobacter + PSB) of Rs. 97288 and Rs. 102005 followed by treatment T11 (75 % RDF + VC@ 5 t/ha+ Azotobacter + PSB) during both the years. Sowing on 20th November with GW 451 produced the highest returns and benefit-cost ratio. These results suggest that combined application of 75 % RDF + vermicompost @ 5 t/ha+ Azospirillum + PSB or 75 % RDF + FYM @ 10 t/ha+ Azotobacter + PSB is effective to get higher yield net return in wheat cultivation, providing valuable insights for farmers and researchers.

Published: March 2011

AbstractInferring a protein's function by homology is a powerful tool for biologists. The Princeton Protein Orthology Database (P‐POD) offers a simple way to visualize and analyze the relationships between homologous proteins in order to infer function. P‐POD contains computationally generated analysis distinguishing orthologs from paralogs combined with curated published information on functional complementation and on human diseases. P‐POD also features an applet, Notung, for users to explore and modify phylogenetic trees and generate their own ortholog/paralogs calls. This unit describes how to search P‐POD for precomputed data, how to find and use the associated curated information from the literature, and how to use Notung to analyze and refine the results.Curr.

Selective and Responsive Nanoreactors
Authors: Renggli Kasper , Baumann Patric , Langowska Karolina , Onaca Ozana , Bruns Nico , Meier Wolfgang 
Published: March 2011

AbstractChemical reactions can be confined to nanoscale compartments by encapsulating catalysts in hollow nanoobjects. Such reaction compartments effectively become nanoreactors when substrate and product are exchanged between bulk solution and cavity. A key issue, thereby, is control of shell permeability. Nanoreactors exhibit selectivity and responsiveness if their shells discriminate among molecules and if access can be modulated by external triggers. Here, we review natural nanoreactors that include protein‐based bacterial microcompartments, protein cages, and viruses. Artificial nanoreactors based on dendrimers, layer‐by‐layer capsules, and amphiphilic block copolymer polymersomes are also discussed. Selectivity in these nanoreactors is either due to intrinsic reactor‐shell semipermeability or can be engineered using smart polymers to gate the reactors. Moreover, a rich repertoire of pores and channels are already provided in nature, e.g., in protein‐based nanoreactors or in trans‐membrane channel proteins. The latter can be reconstituted in polymersomes, resulting in gated vesicles. Nanoreactors hold promise for applications ranging from selective and size‐constrained organic synthesis to biomedical advances (e.g., artificial organelles, biosensing) and as analytical tools to study reaction mechanisms.
Synthesis of 1,4‐Diarylbuta‐1,3‐dienes through Palladium‐ Catalyzed Decarboxylative Coupling of Unsaturated Carboxylic Acids
Authors: Yamashita Mana , Hirano Koji , Satoh Tetsuya , Miura Masahiro 
Published: March 2011

AbstractIt has been found that readily available hydroxylated cinnamic acids such as ferulic acid undergo palladium‐catalyzed decarboxylative coupling with aryl iodides and internal alkynes in a 1:1:1 manner to produce 1,4‐diarylbuta‐1,3‐dienes. The butadiene synthesis has also been achieved through the coupling of aryl halides with dienoic acids. Some of the products exhibit solid‐state fluorescence.
Accessing Skeletal Diversity under Iron Catalysis using Substrate Control: Formation of Pyrroles versus Lactones
Authors: Alcaide Benito , Almendros Pedro , Quirós M. Teresa 
Published: March 2011

Abstract2‐Azetidinone‐tethered alkynols and allenols, readily prepared from a propanylidene β‐lactam aldehyde, were used as starting materials for divergent ring expansion reactions catalyzed by iron(III) chloride. Worthy of note, in contrast to the iron‐catalyzed reactions of β‐lactam allenols which lead to γ‐lactones, the reaction of β‐lactam alkynols under identical conditions gives pyrroles. The gold‐catalyzed 6‐endo aminocyclization of these allenic γ‐lactones formed fused dihydropyridines. The iron‐catalyzed formation of pyrroles may proceed through a Meyer–Schuster rearrangement followed by β‐lactam ring opening and cyclization by attack of the amino group to the ketone.

Published: March 2011

AbstractExperiments were conducted to study the effect of static magnetic fields on the seeds of soybean (Glycine max (L.) Merr. var: JS‐335) by exposing the seeds to different magnetic field strengths from 0 to 300 mT in steps of 50 mT for 30, 60, and 90 min. Treatment with magnetic fields improved germination‐related parameters like water uptake, speed of germination, seedling length, fresh weight, dry weight and vigor indices of soybean seeds under laboratory conditions. Improvement over untreated control was 5–42% for speed of germination, 4–73% for seedling length, 9–53% for fresh weight, 5–16% for dry weight, and 3–88% and 4–27% for vigor indices I and II, respectively. Treatment of 200 mT (60 min) and 150 mT (60 min), which were more effective than others in increasing most of the seedling parameters, were further explored for their effect on plant growth, leaf photosynthetic efficiency, and leaf protein content under field conditions. Among different growth parameters, leaf area, and leaf fresh weight showed maximum enhancement (more than twofold) in 1‐month‐old plants. Polyphasic chlorophyll a fluorescence (OJIP) transients from magnetically treated plants gave a higher fluorescence yield at the J–I–P phase. The total soluble protein map (SDS–polyacrylamide gel) of leaves showed increased intensities of the bands corresponding to a larger subunit (53 KDa) and smaller subunit (14 KDa) of Rubisco in the treated plants. We report here the beneficial effect of pre‐sowing magnetic treatment for improving germination parameters and biomass accumulation in soybean.

Published: March 2011

ABSTRACTA novel method was developed using capillary electrophoresis (CE) coupled with tris(2,2′‐bipyridyl)ruthenium(II) electrogenerated chemiluminescence (ECL) for highly sensitive detection of metformin hydrochloride (MH) derivatizatized with acetaldehyde. The precolumn derivatization of MH with acetaldehyde was performed in phosphate buffer solution (0.3 mol/L, pH 7.5) at room temperature for 120 min. The effects of acetaldehyde concentration, buffer pH, electrokinetic voltage and injection time were investigated. Under optimized detection conditions, the MH ECL detection sensitivity was more than 120 times that without derivatization. The linear concentration range for MH was 0.001–15.00 μg/mL (with a correlation coefficient of 0.9992). The detection limit was 0.31 ng/mL with a signal:noise ratio of 3. The recoveries of MH in human urine were in the range 98.50–99.72%. Copyright © 2011 John Wiley & Sons, Ltd.
Trends in incidence and mortality from abdominal aortic aneurysm in New Zealand
Authors: Sandiford P , Mosquera D , Bramley D 
Published: March 2011

Abstract

Background
This study examined trends in abdominal aortic aneurysm (AAA) incidence and mortality in New Zealand (NZ) and compared these with mortality rates from England and Wales.

Methods
Cause-specific death data were obtained from the NZ Ministry of Health, UK Office for National Statistics and National Archives (for England and Wales). The NZ National Minimum Data Set provided hospital discharge data from July 1994 to June 2009.

Results
In 2005–2007 the age-standardized AAA mortality rate for men was 33·3 per cent less in NZ than in England and Wales (5·21 versus 7·81 per 100 000), whereas for women it was 9·8 per cent less (2·12 versus 2·35 per 100 000). Standardized mortality rates in NZ fell by 53·0 per cent for men and 34·1 per cent for women from 1991 to 2007. Between 1991–1992 and 2005–2007 the probability of a 65-year-old dying from an AAA fell by 28·2 per cent (from 1·872 to 1·344 per cent) in men, and by 6·3 per cent (from 0·837 to 0·784 per cent) in women. New AAA admission and hospital death rates in NZ peaked in 1999 for men, and in 2001 for women, and have since declined sharply. Hospital mortality ratios have also fallen, except for women with a ruptured aneurysm.

Conclusion
The burden of AAA disease has been falling since at least 1991 in NZ, and since 1995 in England and Wales. Although survival appears to be improving, most of the reduction is due to lower disease incidence.

ABSTRACTWarfarin is routinely monitored by assessing its pharmacologic effects on the international normalized ratio. However, having a patient with INR not responding to increasing warfarin dose mandates a direct measurement of warfarin concentrations (total and free) for better patient clinical management of warfarin therapy. Therefore, a new fully validated specific, precise and accurate ultra‐performance liquid chromatography tandem mass spectrometry was developed for the determination of free and total warfarin in human plasma. Free warfarin was measured in plasma filtrate, prepared by ultrafiltration, and sample pretreatment involved protein precipitation with acetonitrile. Linear response (r2 ≥ 0.99) was observed over the studied range of free and total warfarin, with the lower limit of detection of 0.25 ng/mL. The intra‐ and inter‐day precision (relative standard deviation) values were <10% and the accuracy (relative error) was ≤6.6 for free and total warfarin. There was no significant difference (p > 0.05) between inter‐ and intra‐day studies for the free and total warfarin, which confirmed the reproducibility of the assay method. The mean extraction efficiency was 88.6–107.2% of free and total warfarin. The assay was sensitive to follow warfarin pharmacokinetics (free and total) in a patient with resistance to warfarin up to 24 h after a daily dose of warfarin.

A clinical study of those who utter threats to kill
Authors: Warren Lisa J. , Mullen Paul E. , Ogloff James R.P. 
Published: March 2011

AbstractObjectiveThe current study sought to examine the psychiatric characteristics and rate of subsequent violence among those who uttered explicit threats to kill.MethodData were drawn from 144 referrals of adults to a community‐based forensic mental health consultation and treatment service. Each had explicitly threatened to kill a person other than themselves.ResultsAssaults were made by over 20%, including one homicide, within 12 months of assessment. Two participants committed suicide in the follow‐up period. Factors found to contribute to violence risk were substance abuse, prior violence, limited education and untreated mental disorders. Threateners were often habitual in their threatening behaviour and typically targeted those they interacted with on a daily basis. Clinical characteristics showed a psychiatrically complex group who shared many features of other offender groups.ConclusionsThe type of threat that led to referral for a mental health assessment was not uncommonly followed by violence. Factors enhancing risk resemble findings from other groups of offenders. Those referred for clinical evaluation typically have complex clinical presentations and marked deficits in effectively managing interpersonal conflict. Copyright © 2011 John Wiley & Sons, Ltd.
Zwitterionic Iridium Complexes with P,N‐Ligands as Catalysts for the Asymmetric Hydrogenation of Alkenes
Authors: Franzke Axel , Pfaltz Andreas 
Published: March 2011

AbstractSeveral zwitterionic iridium complexes based on chiral P,N‐ligands with imidazoline or oxazoline donors and anionic tetraarylborate or aryltrifluoroborate substituents have been synthesized. The corresponding cationic analogues have also been prepared, to evaluate the effect of the covalent linkage between the anion and the cationic metal complex in catalytic reactions. The respective pairs of structurally analogous precatalysts have been compared for their efficacies in the asymmetric hydrogenation of unfunctionalized olefins. In most cases, the anionic derivatization has virtually no influence on the asymmetric induction of the iridium complex. This is in accordance with X‐ray structural studies, which have shown that the chiral environment of the cationic metal center is not affected by the anionic substituent. Depending on the nature of the counterion employed, the zwitterionic catalysts proved to be significantly more reactive than their cationic counterparts in nonpolar solvents.
Vulnerable Self, Poor Understanding of Others' Minds, Threat Anticipation and Cognitive Biases as Triggers for Delusional Experience in Schizophrenia: A Theoretical Model
Authors: Salvatore Giampaolo , Lysaker Paul H. , Popolo Raffaele , Procacci Michele , Carcione Antonino , Dimaggio Giancarlo 
Published: March 2011

It remains unclear what processes lead to the establishment of persecutory delusions in acute phases of schizophrenia. Recently, it has been argued that persecutory delusions arise from an interaction among a range of emotional, cognitive and social factors. In this work, we explored this possibility by first discussing the relevant aspects of recent theoretical models of the causes of persecutory delusions. Then, we offered an analysis of the literature, illustrated with clinical observations suggesting that persecutory delusions are triggered during stressful intersubjective transactions by the interactions of (a) an alteration in empathetic perspective taking and in pragmatic understanding of others' minds; (b) a perception/representation of the self as vulnerable or subordinate and of the other as dominant and threatening; and (c) a hyperfunctioning of the threat/self‐protection system when faced with perceived danger. Implications for future research and treatment of people suffering from this symptom are discussed. Copyright © 2011 John Wiley & Sons, Ltd.Key Practitioner Message

MicroRNAs and their predicted target messenger RNAs are deregulated by Exposure to a Carcinogenic Dose of Comfrey in Rat Liver
Authors: Li Zhiguang , Fuscoe James C. , Chen Tao 
Published: March 2011

AbstractMicroRNAs (MiRNAs) are small noncoding RNAs that function as regulators of gene expression to control cell growth and differentiation. In this study, we analyzed miRNA and mRNA expression in the livers of rats treated with a carcinogenic dose of comfrey (Symphytum officinale) for 12 weeks. Groups of six rats were fed a normal diet or a diet containing 8% comfrey root. The animals were sacrificed 1 day after the last treatment and the livers were isolated for miRNA expression analysis using LC Sciences miRNA microarrays and for mRNA expression analysis using Affymetrix rat genome microarrays. MiRNA expression levels were significantly changed by comfrey treatment. The treated samples were separated clearly from the control samples in both principal component analysis (PCA) and hierarchical clustering analysis (HCA). Quantitative measurements of seven miRNAs using TaqMan real‐time PCR were consistent with the microarray results in terms of fold‐change and the direction of the change in expression. Forty‐five miRNAs (P < 0.01) and 1,921 mRNAs (q = 0) were significantly changed by comfrey treatment. Using a target prediction algorithm, 434 differentially expressed genes (DEGs) were predicted to be targeted by the differentially expressed miRNAs (DEMs). The DEM‐targeted DEGs were more likely to be involved in carcinogenesis than the DEGs that were not targeted by the DEMs. The nontargeted DEGs were enriched in noncancer‐related biological processes. Our data suggest that comfrey may exert its carcinogenic effects by disturbing miRNA expression resulting in altered mRNA levels of the DEM‐targeted genes that are functionally associated with carcinogenesis.
