The aim of this study is to assess the effect of footwear on postural status of a group of volunteers representing the general population of female students. Based on the assumption that the elegant shoe with tapered toe and high heel does not provide adequate foot support, the study was designed to assess its direct link and impact to body segment alignment and resulting negative effect on posture. Repetition of this misalignment ensures the individual circumstances of posture. Due to the heel elevation, the weight is transferred to the distal part, resulting in a postural response of the entire musculoskeletal system to maintain balance. The group consisted of 30 women of the age 18–28 years with an average age of 22.7 years, height 167±0.3 cm and weight 57±0.9 kg. Anamnesis and aspection were performed to assess of the occurrence of shortened and weakened muscles and subsequently the patient's standing was examined. Two static methods were chosen for evaluation of the posture. The first one was the Silhouette Posture Analysis and the evaluation method by Jaros and Lomnicka. The result was the identification of typical muscle imbalance as the most common presumption of faulty posture, and it was confirmed that footwear affects a person's natural posture. Differences in the sensitivity of the two methods were also identified and studies are not only appropriate that but also evaluate differences in impact among subjects.

Abstract To account for the effects of multiple impairments, evaluating physicians must provide a summary value that combines multiple impairments so the whole person impairment is equal to or less than the sum of all the individual impairment values. A common error is to add values that should be combined and typically results in an inflated rating. The Combined Values Chart in the AMA Guides to the Evaluation of Permanent Impairment, Fifth Edition, includes instructions that guide physicians about combining impairment ratings. For example, impairment values within a region generally are combined and converted to a whole person permanent impairment before combination with the results from other regions (exceptions include certain impairments of the spine and extremities). When they combine three or more values, physicians should select and combine the two lowest values; this value is combined with the third value to yield the total value. Upper extremity impairment ratings are combined based on the principle that a second and each succeeding impairment applies not to the whole unit (eg, whole finger) but only to the part that remains (eg, proximal phalanx). Physicians who combine lower extremity impairments usually use only one evaluation method, but, if more than one method is used, the physician should use the Combined Values Chart.

Pornography is a debatable subject, both in Malaysia and around the world. Some feel it is harmless while others feel it is damaging. Pornography can bring about its own impact to the viewers. In Malaysia, the trend of viewing pornography among youngsters’ has been increasing. Studies have also shown Pornography can lead to unhealthy behaviors as a result of too much viewing. This study was conducted to discover the addiction level and the consumption effects on students at a Malaysian University. The researchers used purposive sampling to distribute questionnaires. The Scale used was the Internet Pornography Addiction Test and the Pornography Consumption Effects Scale consist of Positive and Negative dimension used to conduct the research. The research population (N=120) was students’ from University Tunku Abdul Rahman of Malaysia. There were significant relationship between the addiction and consumption. There were significant differences between the Positive and Negative Dimension as well. The Negative Effect Dimension is higher than the Positive Effect Dimension. There were significant differences between male and female students towards pornography addiction. However, there were not any significant differences among the genders in internet consumption. Male scored higher than female in the Internet Pornography Addiction. There were no significant differences between gender in the Positive and Negative Dimension.

AbstractSmall sensor devices like inertial measurement units enable mobile movement and gait analysis, whereby existing systems differ in data acquisition, data processing, and gait parameter calculation. Concerning the validation, recent studies focus on the captured motion and the influence of sensor positioning with respect to the accuracy of the computed biomechanical parameters in comparison to a reference system. Although soft tissue artifact is a major source of error for skin-mounted sensors, there are no investigations regarding the relative movement between the body segment and sensor attachment itself. The aim of this study is to find an evaluation method and to determine parameters that allow the validation of various sensor attachment types and different sensor positionings. The analysis includes the comparison between an adhesive and strap attachment variant as well as the frontal and lateral sensor placement. To validate different attachments, an optical marker-based tracking system was used to measure the body segment and sensor position during movement. The distance between these two positions was calculated and analyzed to determine suitable validation parameters. Despite the exploratory research, the results suggest a feasible validation method to detect differences between the attachments, independent of the sensor type. To have representative and statistically validated results, further studies that involve more participants are necessary.

Objective:The Scripps neurologic rating scale (SNRS) is a summary measure of individual components comprising a neurological examination, designed for use in multiple sclerosis (MS). Our objective is to evaluate the responsiveness of the SNRS, within the context of a 2-year, randomized, double-blind crossover study of the efficacy of cladribine for treatment of secondary progressive MS.Methods:Effect sizes were determined for the SNRS and its components, separately for each treatment group (initial placebo, and initial cladribine) over both years of the clinical trial, using a standard random effects model.Results:Individual components tended to show positive effect sizes (improvement) during periods of active therapy in both treatment groups, and negative effect sizes (deterioration) during periods of no active therapy. Summation indices derived from the individual components of the SNRS seemed somewhat more stable than the individual components. The two components mentation and mood, and bladder, bowel, or sexual dysfunction, were rather unresponsive in our clinical trial.Conclusion:Changes in the components of the SNRS over the course of our clinical trial were consistent between the two treatment groups. Most components were moderately responsive; and, the summary SNRS score appropriately summarized the moderate magnitudes of change evinced in the individual components.

Decoupling the individual effects of multiwalled carbon nanotubes (MWCNTs) and surfactants when used as reinforcement materials in cement-based composites is aimed in this study. Powder MWCNTs were dispersed in deionized water using different types of surfactants as chemical dispersing agents and an ultrasonic tip processor. Cement pastes with carbon nanotubes additions of 0.15% by mass of cement were produced in two steps: first, the MWCNT/surfactant dispersions were combined with the mixing water, and then, cement was added and mixed until a homogeneous paste was obtained. Mechanical properties of the pastes cured at 7 days were measured, and their fracture behavior was characterized using the linear elastic finite element analysis. It was found that the reinforcing effect of MWCNT was masked by the negative effect of surfactants in the cement matrix; nevertheless, nanotubes were capable of increasing both stress and strain capacity of the composite by controlling the crack propagation process at the tip of the crack.

Abstract This article analyzes the effects of income taxation on the international migration and earnings of top earners using a Danish preferential foreigner tax scheme and population-wide Danish administrative data. This scheme, introduced in 1991, allows new immigrants with high earnings to be taxed at a preferential flat rate for a duration of three years. We obtain two main results. First, the scheme has doubled the number of highly paid foreigners in Denmark relative to slightly less paid—and therefore ineligible—foreigners. This translates into a very large elasticity of migration with respect to 1 minus the average tax rate on foreigners, between 1.5 and 2. Second, we find compelling evidence of a negative effect of the scheme-induced reduction in the average tax rate on pretax earnings of foreign migrants at the individual level. This finding can be rationalized by a matching frictions model with wage bargaining where there is a gap between pay and marginal productivity.

Partnership is not a new phenomenon in the university environment. It embraces strategies used by people with common interest to harvest knowledge in terms of sharing or collaboration. However, the case differs with collaborations in Library and Information Science (LIS) research in Africa, especially LIS scholars in African universities in Nigeria and Zimbabwe. Paucity of empirical literature is available on research collaboration among LIS scholars in Nigerian and Zimbabwean universities. The purpose of the study was to examine partnership among librarians, with reflection on observation and interview research reports in three universities in Nigeria and Zimbabwe. The study adopted a qualitative approach using interview to gather data from librarians drawn from three Nigerian and Zimbabwean universities. The qualitative research approach grounded on content analysis of documents/literature, observation and interview method was use for the study. The observation focus on the authors’ exposition in the sampled universities environment, while the interview were key informants from each of the three countries universities sampled. The study consider the collaborative theory through grounded method. The findings of the study revealed lack of trust in the individual or groups collaborator; team members have the feeling that the project they are collaborating on is of little benefit, due to poor relationship. Team members see themselves as contender or challenger; which has affected leadership issue and involvement of long meetings and inability to address the truth. In terms of the influence of collaboration on professional growth of librarians, result demonstrated enhancement of teaching aspect of librarianship, learning and research quality; promote cooperation, coordination, which in turn increased level of intensity, tenacity and interaction among members. Linkage among LIS professional ranges from networking, cooperation, alliances, coordination and partnership, coalition and eventually collaboration. Challenges reported include catastrophic consequent on negative effect of work, culture and stylistic parameters including concept, attitude and professional hindrances. dominance impact of policies and procedures of collaboration, exploitation of the weak members, lack of clarity and rationale behind the collaboration, unwillingness to change by members in collaboration, lack of socialisation, largeness of the group, wrong membership and jettisoning of members ideas which eventually make some members take the decision of quitting the team. The study recommends inter-disciplinary, intra-institutional and inter-institutional collaboration among various stakeholders in LIS education and training.

AbstractCockroaches, like most social arthropods, are led to choose collectively among different alternative resting places. These decisions are modulated by different factors, such as environmental conditions (temperature, relative humidity) and sociality (groups size, nature of communications). The aim of this study is to establish the interplay between environmental conditions and the modulation of the interactions between individuals within a group leading to an inversion of preferences. We show that the preferences of isolated cockroaches and groups of 16 individuals, on the selection of the relative humidity of a shelter are inversed and shed light on the mechanisms involved. We suggest that the relative humidity has a multi-level influence on cockroaches, manifested as an attractant effect at the individual level and as a negative effect at the group level, modulating the interactions.

The Banking sector acts as the life blood of modern trade and economic development. Commercial banks influence, facilitate and integrate the economic activities like resources mobilization, poverty elimination, production, and distribution of public finance. The financial performance of commercial banks has great implications in the financial sector and in the country at large, and will still remain an important subject of concern by all the stakeholders in the banking industry. In the last two decades, a lot of banking innovation has taken place in order to improve commercial banks financial performance. Branchless banking which involves the use of agency banking and electronic banking channels in the distribution of banking products and services is one such innovation. This study purpose was to evaluate the effect of branchless banking on the financial performance of commercial banks in Kenya. The specific objectives of the study were to analyze the individual effects of agency banking and electronic banking channels on the financial performance of commercial banks in Kenya and the combined effect of both agency and electronic banking on the financial performance of commercial banks in Kenya. The study adopted an exploratory research design. A survey of all the 42 licensed commercial banks in Kenya was done. Both primary and secondary data on branchless banking and financial performance of banks was obtained from the individual commercial banks, Central Bank of Kenya banking annual supervision reports respectively. Return on Assets (ROA) was used as the main indicator of commercial banks financial performance. The amount of investment in agency and electronic banking was used as indicator for agency and electronic banking. Data analysis was done using SPSS and STATA statistical softwares. Descriptive statistics, diagnostic tests and tests of hypothesis were done. Data was presented using tables and charts. Study findings indicated that when used in isolation; both agency and electronic banking had a significant negative effect on the financial performance of commercial banks at 5 percent significance level. However, when agency and electronic banking channels were used together as a multichannel strategy, they had a significant positive effect on bank’s financial performance at 5 percent significance level. The study recommends that for positive returns, commercial banks should invest in both agency and electronic banking as a multichannel strategy since these channels are complimentary to each other.
