This study examines the instructing of standardized physical fitness assessment in a mobile environment. The main focus of this research was to determine if the fitness tests can be performed with correct techniques with the aid of a mobile application. Different types of visual aids, instructions and mobile devices were evaluated and compared in relation to usability and prevalence of errors. A prototype of a mobile fitness assessment application, My Energy Test, was used in a 2 x 2 x 3 between-subjects user study with a total of 72 participants. Data was gathered using a postquestionnaire and recording user tests. The questionnaire measured the perceived usability, and video recordings were analyzed for deviations, i.e. errors, from the correct test techniques. Main findings show that the device used did not have an effect on the perceived usability, but influenced the quantity of errors made. Moreover, it was found that audio and text instructions were perceived with equal usability with each other. The visual aid used had a statistically significant effect on the perceived usability score with video and picture series being rated more favorably compared to animation. The best combination of least amount of errors and perceived usability was observed when either video or picture series visual aid was combined with text instructions. It was concluded that standardized physical fitness tests can be carried out with sufficient correctness without the help of a professional instructor.
A Stochastic Multi-Temporal Optimal Power Flow Approach for the Management of Grid Connected Storage

Renewable energy (RE) integration into distribution grids is becoming more common in the context of the energy transition. The management of wind or solar generation due to their variability and low predictability are challenging for distribution system operators (DSO). To that may be added uncertainties related to electric load profiles. The role of flexibility, coming from decentralized storage devices, will be important for DSOs trying to manage uncertain loads as well as high levels of RE penetration. The introduction of automation and smart metering in distribution grids allows for the optimized management of storage devices to maximize the capability of current infrastructure to integrate RE generators. These optimized management strategies can be calculated with optimal power flow (OPF) algorithms. This paper uses a convex relaxation of the power flow equations to expand the multi-temporal deterministic approach presented in [1] to a stochastic one. The stochastic algorithm implies the integration of a scenario tree to plan the charging and discharging schedule of batteries one day in advance. When comparing deterministic and stochastic operation planning strategies, the stochastic method annually increases total economic benefit by 3.1% while requiring lower annual cycling of the battery therefore increasing battery life.
Life and work on small-scale farms in Norway: an outlook based on survey results linked to financial data

This paper studies what causes (small-scale) farmers to leave their farms and typically move to urban areas. A data set is constructed by linking survey results with financial data, and the data set is analyzed by multivariate statistical techniques. Our results indicate that, while existence and size of future farm production is important, there is also a difference between farmers who primarily have financial objectives for their farming, and those who have more lifestyle oriented objectives. The latter group is, everything else being equal, more likely to stay on the farm. This could imply that, if preventing migration from rural to urban areas is a policy objective, production support schemes will be effective for some groups, but will be less effective for the group with lifestyle objectives. If this group is to be encouraged to stay on the countryside, policies directed at improving the general living conditions in the local community are likely to be more effective than specific support schemes related to agricultural production.
Surface polaritons with arbitrary magnetic and dielectric materials: new regimes, effects of negative index, and superconductors

A surface magnon-polariton can be excited by both p- and s-polarized light if at least one of the layers is a magnetic material. We present general expressions of the tangential wave vectors of s- and p-polarized light at an interface of two media. Analysis reveals additional new regimes of surface polariton resonances with magnetic materials for s- and p-polarized light. The tangential wave vectors are found to be equal in magnitude to the normal wave vectors at surface polariton resonances. The spatial distributions of the fields at resonant enhancement and the spectra of the tangential wave vectors are studied for different dielectric permittivities and magnetic permeabilities of the two media. If one of the media has dispersive dielectric function and permeability function, additional surface polariton resonance peaks appear for both s- and p polarizations. For a medium with a superconductor, the tangential component increases asymptotically at lower frequencies, providing subwavelength capability at the terahertz regime.
Likelihood Inferences on Semiparametric Odds Ratio Model

A flexible semiparametric odds ratio model has been proposed to unify and to extend both the log-linear model and the joint normal model for data with a mix of discrete and continuous variables. The semiparametric odds ratio model is particularly useful for analyzing biased sampling designs. However, statistical inference of the model has not been systematically studied when more than one nonparametric component is involved in the model. In this article, we study the maximum semiparametric likelihood approach to estimation and inference of the semiparametric odds ratio model. We show that the maximum semiparametric likelihood estimator of the odds ratio parameter is consistent and asymptotically normally distributed. We also establish statistical inference under a misspecified semiparametric odds ratio model, which is important when handling weak identifiability in conditionally specified models under biased sampling designs. We use simulation studies to demonstrate that the proposed approaches have satisfactory finite sample performance. Finally, we illustrate the proposed approach by analyzing multiple traits in a genome-wide association study of high-density lipid protein. Supplementary materials for this article are available online.
Proteome-Wide Analysis of Cysteine Reactivity during Effector-Triggered Immunity1[OPEN]

Increase in the level of reversible oxidation states during the plant immune response affects cysteines in a wide range of proteins, follows a wave pattern with a maximum at eight hours after pathogen infection, and is modulated by the oligopeptidases TOP1 and TOP2. A surge in the accumulation of oxidants generates shifts in the cellular redox potential during early stages of plant infection with pathogens and activation of effector-triggered immunity (ETI). The redoxome, defined as the proteome-wide oxidative modifications of proteins caused by oxidants, has a well-known impact on stress responses in metazoans. However, the identity of proteins and the residues sensitive to oxidation during the plant immune response remain largely unknown. Previous studies of the thimet oligopeptidases TOP1 and TOP2 placed them in the salicylic acid dependent branch of ETI, with a current model wherein TOPs sustain interconnected organellar and cytosolic pathways that modulate the oxidative burst and development of cell death. Herein, we characterized the ETI redoxomes in Arabidopsis (Arabidopsis thaliana) wild-type Col-0 and top1top2 mutant plants using a differential alkylation-based enrichment technique coupled with label-free mass spectrometry-based quantification. We identified cysteines sensitive to oxidation in a wide range of protein families at multiple time points after pathogen infection. Differences were detected between Col-0 and top1top2 redoxomes regarding the identity and number of oxidized cysteines, and the amplitude of time-dependent fluctuations in protein oxidation. Our results support a determining role for TOPs in maintaining the proper level and dynamics of proteome oxidation during ETI. This study significantly expands the repertoire of oxidation-sensitive plant proteins and can guide future mechanistic studies.
Bioassay-guided investigation of Lonchocarpus cyanescens benth leaves extracts for antioxidant activities

Antioxidants have been reported to prevent oxidative damage caused by free radicals and can be used to ameliorate conditions in cardiovascular and inflammatory diseases. Ethnobotanical study revealed that the leaves of Lonchocarpus cyanescens are traditionally used in Africa to treat ulcer and arthritis. This study investigates the antioxidant activities of its extract and fractions. Acetone leaf extract of L. cyanescens was screened for 2,2-diphenylpicrylhydrazyl (DPPH) free radical scavenging activity, ferric reducing power (FRAP), total phenol content and total flavonoid content using catechin as standard antioxidant. Bioguided column chromatographic separation was carried out and the resultant fractions were screened for antioxidant activities. Preliminary spectroscopic profile of the most active fraction was obtained. DPPH and FRAP methods showed that L. cyanescens had antioxidant activity which correlated with its phenolic and flavonoid contents. There was a higher correlation of the total phenol/flavonoid content to the antioxidant activity by the DPPH method [r2 = 0.9906, 9926 respectively] than the FRAP method [0.8635, 8840 respectively]. Bioactivity guided fractionation identified fraction F5 as the most active. 1 H and Infrared spectra indicated that the most active fraction contained flavonoids. Comprehensive in-vivo studies and toxicity profile of the extract will be required before considerations for development as a phyto-drug.

Impact of Livelihood Diversification on Rural Households' Food Security in Fedis Weroda, Eastern Hararge Zone, Oromiya Regional State, Ethiopia

Most rural populations in Africa have been suffering from poverty and environmental degradation. African's diversify their livelihood strategies to mitigate risks. This study presents the impact of livelihood diversification on rural household food security, Moreover, the study identified livelihood activities employed by households, determine food security status of households and also identify determinants of livelihood diversification. The study employed a two stage random sampling procedure. 180 sample households were used for the study. Mean, percentage, frequencies, t-test chi-square test and an econometric model of PSM were used for analysis. The study found that in the study area households practice different activities in addition to agriculture. The most commons are pity trade (shops, large animal trading, chat retailing, charcoal sell and ground nut retailing) and local wage labor. The study also found that among the total households 61.2% were found to be food secure and 38.8% of them food insecure. Moreover, food secure and insecure households shows a significant mean difference with respect to age of the household head, education year of the household head ,number of times the household received extension service in a year and participation in productive safety net program. The descriptive statistics for diversified and not diversified households shows that the two groups had a significant mean difference with respect to education year of the household head, number of times the household received extension service in a year, participation in productive safety net program and calorie intake by the household members in adult equivalent. The logistic regression model also shows that education year of the household head, membership to cooperatives, number of times the household received extension service in a year and participation in productive safety net program significantly affect diversification. Results from propensity score matching shows that livelihood diversification brought a positive impact on households' food security by showing that the mean difference in calorie intake is significant at less than 1% probability level.The study concluded that livelihood diversification can have a positive impact on rural households' food security. Therefore it is advisable to encourage rural households' participation in different activities in addition to agriculture. Keywords : livelihood diversification, food security, propensity score matching
Compliance with International Financial Reporting Standards by Listed Companies in Ghana

This study examined the extent to which companies listed on the Ghana Stock Exchange (GSE) comply with International Financial Reporting Standards’ (IFRSs) presentation and disclosure requirement. With the aid of a checklist, an index of compliance was devised to quantify the level of compliance. This was applied to the 2010 financial statement of 31 companies listed on the GSE. Descriptive statistics was used to analyse the extent of compliance by companies categorised in line with industry classification of the GSE. The study further examined relationships between company attributes and the extent of compliance. In addition, factors influencing the extent of IFRSs compliance are revealed using correlation and multiple regression analysis. ANOVA was employed to explore statistically significant differences between industry types with regards to their extent of compliance. The findings revealed an overall mean compliance of 85.8% in Ghana. Company attributes of size, profitability, auditor type, internationality and industry type associate positively with IFRSs compliance. ANOVA results revealed differences between industry types with regards to their compliance rate. The study recommends that the Institute of Chartered Accountants Ghana liaise with regulators to organise regular training programmes for companies to provide a practical guide for full compliance since the IFRSs receive continuous amendment.

It has been validated by simulation and experimentally with one Ga, power transistor and two Si MOSFETs. Results show good agreement between measurements and the model.
Molecular characterization and genetic diversity analysis of different rice cultivars by microsatellite markers

A total of 52 rice SSR markers well distributed on 12 chromosomes were used to characterize and assess the genetic diversity among ninety four rice genotypes. The total number of polymorphic alleles was 361 alleles with the average of 5.86 alleles per SSR locus. The study revealed that some markers such as RM276 and RM5642 on chromosome 6 and RM14 and RM1 on chromosome 1 have more than 9 observed alleles compared to other primers like RM16, RM207, RM208 and RM317 with 3-4 alleles. The highest and lowest PIC values were observed for primers RM276 (0.892 and RM208 (0.423) respectively. Using Shannon´s diversity index, a mean genetic diversity of 1.641 was obtained from the analysis, indicating a high level of genetic variation among these cultivars. Cluster analysis using the complete linkage method based on jaccard similarity coefficient revealed that all genotypes were classified to nine clusters at genetic similarity level of 0.010. 75, which contained 12, 16, 2, 18, 3, 6, 16, 10 and 11 varieties, respectively. Results of discriminant analysis showed that the nine cluster groups were confirmed at high levels of correct percent (96.8) and revealed true differences among these clusters. As a final result from this study, we selected eight cultivars from different cluster including Daylamani, Tarom mohali (landrace rice cultivars), RI1843046, Back cross line, RI184472, RI184421 (promising cultivars), Line 23 and IR50 (IRRI lines) as parents. All of the selected cultivars will be arranged in complete diallel design to obtain combining abilities, gene effects and heterosis for each important morphology and physico-chemical characters.

The survey was based on a representative sample of all children born in Scotland in 1936. They were first surveyed in 1947 and then almost annually to 1963. The focus of the paper is on the legacies of several waves of reform to secondary education in the first half of the twentieth century. The main research questions are whether the reforms extended access to educational attainment up to age 27 and thus widened access to high-status occupations. These questions are investigated using mainly multiple linear regression. The conclusions are that access was extended, but that people who had attended the older-established secondaries that pre-dated the reforms were more successful educationally and occupationally than people who attended newer foundations, even controlling for social background and intelligence. This effect was especially pronounced for pupils of above-average intelligence, the old schools providing them with particularly pronounced opportunities in adulthood.

Phantom limb visualization in first-person perspective using a head-mounted display to treat Phantom Limb Pain (PLP)

Phantom Limb Pain (PLP) is a seriously disabling condition faced by the majority of amputees. Ortiz-Catalan et al. introduced, in 2014 a novel medical treatment for PLP showing promising results in clinical studies. The Head Mounted Display (HMD) is an interesting interface to serve this novel treatment more efficiently and more broadly to a larger number of patients. HMDs have lately reached massmarket potential. This thesis looks into, and applies, HMD technology to the novel treatment for PLP. First, HMD technology and software libraries that allow the development of VR/AR experiences are analysed for their suitability for the novel treatment. Then, the implementation of the novel treatment for PLP utilizing HMD technology is described. Finally, computer graphical improvements are proposed to this initial implementation of the novel treatment for PLP utilizing HMD technology. To analyse HMD technology and the software libraries in the framework of this thesis, first, the requirements of the novel treatment utilizing HMD technology are elicited. This elicitation is performed by means of a review of the work by Ortiz-Catalan et al. as well as observing a treatment session. A number of hardware options are analysed in order to determine if they may be used in the medical field, if they bear additional requirements to that particular hardware option, and what software might be used to develop for that particular hardware option. A number of software options are analysed in order to determine if they may be used in the medical field, what might be achieved with them, and under which license they are published. Both hardware and software options are analysed by researching published material. The implementation is described by pointing out a number of interesting challenges faced during the implementation. The graphical improvements to the initial implementation of the novel treatment for PLP utilizing HMD technology are analysed by explaining how they may be implemented, how they may improve the embodiment illusion, and how they impact the performance. The outcome of the research shows that indeed HMD technology might be suitable to treat PLP by the novel treatment introduced by Ortiz-Catalan et al.
