Light and Heavy Heterosexual Activities of Young Canadian Adolescents : Normative Patterns and Differential Predictors Trish Williams Alberta Children ’ s Hospital

The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal Survey of Canadian Children and Youth (NLSCY) in which heterosexual behaviors, as well as puberty, parenting processes, peer self-concept, and problem behaviors were examined. The heterosexual activities of the majority of 12and 13-year-old adolescents were largely confined to light activities of hugging, holding hands, and kissing. Heavy activities such as petting and sexual intercourse were reported less often. Using predictor variables from Cycle 1 of the NLSCY when participants were 10and 11-year-olds, SEM analyses indicated that puberty and higher peer selfconcept shared significant direct pathways to both light and heavy heterosexuality. Heavy sexual activity, however, was uniquely associated with the risk factors of adolescent problem behaviors. Positive and hostile parenting styles were indirectly associated with light sexual activity through peer selfconcept. Positive and hostile parenting styles were also indirectly associated with heavy sexual activity through both peer-oriented self-concept and problem behaviors. Results support differential patterns and predictors of light and heavy sexuality in early adolescence. JOURNAL OF RESEARCH ON ADOLESCENCE, 18(1), 145–172 Copyright r 2008, Crown Copyright
InVitro Propagation of Muña-Muña ( Clinopodiumodorum ( Griseb . ) Harley ) Marı́a

A micropropagation protocol was developed which may assist in the safeguarding and augmentation of dwindling natural populations of Clinopodium odorum (Griseb.) Harley, a critically and endangered medicinal plant. Factors affecting culture initiation bud sprouting and growth, rooting, and acclimatization were studied, using nodal segments of in vitro germinated seedling as primary explants on six media supplemented with different concentrations and combinations of 6-benzylaminopurine (BAP) (0.5–1.5 and 2-Naphthalene acetic acid (NAA) (0.5–1.5). Best results for culture initiation with sustainable multiplication rates (100%) were obtained on WP medium without any growth regulator. WP with the addition of 0.5 : 1 or 0.5 : 1.5) of BAP and NAA promoted a higher elongation; however, the optimum number of nodes were obtained in plantlets grown on 1/2 MS with the addition of 1 : 1.5 of BAP and NAA. Culture of sectioned individual nodes transferred to the media with different rates of BAP and NAA 1/2 MS-9 (1.5 : 1.5), SH-8 (1.5 : 1.0), and 1/2 B5-4 (1.0 : 0.5) media resulted in no proliferated shoots. The in vitro plants were successfully acclimatized garden soil and sand (2 : 1) in the greenhouse, with over 90% survival rate. The in vitro-grown plants could be transferred to ex vitro conditions and the efficacy in supporting ex vitro growth was assessed, with a view to develope longer-term strategies for the transfer and reintroduction into natural habitats.
The Open Access Israeli Journal of Aquaculture – Bamidgeh

A 70-day feeding trial was conducted to elucidate the effects of different iron (Fe) sources on growth and Fe concentrations in the tissues, organs, and blood of genetically improved farmed tilapia (Oreochromis niloticus). Five experimental diets (45.0% crude protein, 3.7% crude lipid) with the same Fe concentration (100 mg/kg of feed) were formulated from different Fe sources: ferrous sulfate (FeSO4), ferric chloride (FeCl3), ferrous chloride (FeCl2), ferrous citrate (C6H5FeO7), and iron porphyrin (Fe-porphyrin). The results showed that the percent weight gain (%WG) of fish in the FeCl2 group was the greatest among all five groups (p < 0.05). With %WG as the main indicator, FeCl2 was the most suitable source of dietary Fe for O. niloticus.In the FeCl2 group, the content of Fe in the spleen was significantly greater than that in the C6H5FeO7 group on day 28, and that of the FeSO4 group on day 56. The Fe concentrations in the liver, spleen, gill, vertebra, blood, whole intestine, and dorsal white muscle of O. niloticus were not significantly affected by different dietary sources of Fe on day 70. There were only slight dynamic changes to the Fe content of tissues and organs during the experimental period. The Fe contents in different tissues and organs were as follows: spleen > mid-hind intestine > liver > gill, muscle, foregut > spine. The spleen had the highest Fe content in all groups on day 70. These results suggest that FeCl2 is the best source of dietary Fe for O. niloticus with %WG as the main indicator.

In-vitro evaluation of the synergistic antimicrobial activities of Zingiber officinale ( Rosc ) and Tridax procumbens ( Linn ) against selected pathogenic bacteria

Article Type: Full Length Research Article Antimicrobial combination therapy is an attractive approach in the treatment of polymicrobial infections and in the enhancement of the activities of antimicrobial agents. Combination effect of the antimicrobial activities of aqueous, ethanol and petroleum ether extracts from Zingiber officinale R. and leaves of Tridax procumbens L. were evaluated using the checkerboard dilution technique against typed and clinical isolates of five common human pathogenic bacteria species. The susceptibility of the pathogenic bacteria species to the plant extracts in single and combination application were obtained using the agar well diffusion method while the minimum inhibitory concentration (MIC) were determined using agar dilution method. The combined plant extracts generally showed a better antimicrobial activity than the single application of the extracts during preliminary susceptibility screening. A 12.33±0.58 mm zone of inhibition was recorded for the combination of the petroleum ether extract of the two plants against P. vulgaris ATCC 25933 while the Z. officinale and T. procumbens extract respectively showed 9.33±0.16 mm and 8.67±0.58 mm diameter of inhibition. Also a MIC of 50 mg/ml was observed for the ethanol extract in combination against clinical isolates of K. pneumoniae while in single application MIC of 100 mg/ml were recorded for both plant extracts. Some of the plant extracts also showed good comparison with 5 mg/ml of chloramphenicol, the combined petroleum ether extracts showed an activity index of 1.011 and 1.028 against the clinical isolates of K. pneumoniae. The results from this study showed that combination of purified antimicrobial agents from Z. officinale, a sweet smelling spice and T. procumbens, a noxious weed can be a source of potent antibacterial agent even against resistant pathogenic bacteria strains. ©2014 BluePen Journals Ltd.

Formant Analysis System for Realtime Electromagnetic Interference Source Discrimination

We studied a formant analysis system that extracts characteristic frequencies of acoustic noise generated by telecommunication equipment as a result of electromagnetic interference. Our realtime formant analysis system is based on linear predictive coding and digital signal processors. We checked the system’s technical conditions for formant analysis and found that characteristic frequencies could be obtained even when the signal-to-noise ratio of the waveform was –5 dB.

USING TEMPORAL AM-FM COMBINATION

The efficiency of multistream speech recognizers is investigated by performing several experiments. In order to take advantage of multistream features, each stream should compensate the weakness of the other streams. Our objective is to utilize frequency modulation (FM) which can compensate errors from traditional analysis methods. In order to achieve informational independence from other features based on the spectral/time envelope of signals, our features do not contain amplitude information, but contain temporal structure information of frequency modulation. Our method is evaluated by the continuous digit recognition of noisy speech. We confirmed that our AM-FM combination method is efficient for noisy speech recognition.
Fast and Efficient Sinusoidal Frequency Estimation by Using the DFT Coefficients

Fast and accurate frequency estimation of a complex sinusoidal plays an important role in many applications, including communications, radar, and sonar. This paper presents two methods for the frequency estimation of a complex sinusoidal in noisy environments. The proposed methods interpolate on shifted DFT coefficients to acquire the frequency estimates iteratively. The first method interpolates on the <inline-formula> <tex-math notation="LaTeX">$q$ </tex-math></inline-formula>-shifted DFT coefficients of the signal, whose optimum iteration number is found to be a logarithmic function of the signal length. Furthermore, we also show that by appropriately selecting the value of the shift <inline-formula> <tex-math notation="LaTeX">$q$ </tex-math></inline-formula>, the proposed method becomes asymptotically efficient. In the second method, we use hybrid half-shifted and <inline-formula> <tex-math notation="LaTeX">$q$ </tex-math></inline-formula>-shifted DFT interpolators together, which converges in only two iterations. It is shown that both of the estimators are asymptotically unbiased with their mean square errors performing on the Crámer–Rao lower bound. Theoretical results are validated by extensive computer simulations.
How to Always Keep an Eye on the User with a Mobile Robot ? *

Using mobile robots in rehabilitation is an upcoming trend in the field of robotic healthcare. A possible application is robot assisted self-training after orthopedic knee or hip endoprosthesis surgery. In this scenario, it is particularly important to be able to continuously observe the patients movements in order to give timely feedback on the ongoing exercise. This paper presents a complementary approach separately taking care of two fundamental prerequisites of an application scenario where a user performs gait retraining in rehabilitation under supervision of a mobile robot: driving at a certain constant distance in front of the user and keeping the user at a suitable position in the sensor’s field of view. We show the applicability of our approach under laboratory and real-world conditions.
Dynamic context-aware information access in virtual organizations

Virtual organisations in construction are very dynamic in their composition and operability. In this paper we describe an approach for the realisation of context-aware access management, mapping the required dynamic VO behaviour in an ICT environment with the help of a generic platform ontology describing the actors, resources and processes of a VO and enabling personalised context-specific user support complemented with role-based business, access and representation profiles. To demonstrate and verify the benefits of the suggested approach a set of services for cross-organisational defect management have been implemented. For this specific sub-area of construction the developed ontology has been extended to store metadata on defect records for tracking and corresponding media data (photos, memos, videos etc.) for the documentation of found defects. By combining the RBAC and ABAC models the developed platform ontology provides for creation of context-aware access permissions to control service access, information access and data representation using flexible access rules. Reported is research undertaken in the frames of the German BauVOGrid project performed by 3 academic and 6 industry partners (2007-2010).
Statement Integrated Data Analysis on Heterogeneous Data Source 1 Research Background

A crucial aspect common to many areas of our life is the huge amount of data generated daily. This data covering business, software development, sociology, and other important domains provides a rich source of useful information that can support decision making. This brings the need for efficient yet effective data analytics approaches. A crucial challenge is the effective analysis of heterogenous data sources. In many scenarios, the situation is similar to the story of “The blind men and an elephant”; often we have various pieces of information on a particular topic spread out in various data sources. Individually, the information might be of limited use and might even be contradictory to one another. However, by integrating them together we could get the complete picture which could guide a decision maker to make a wise decision. Data resides in different forms, ranging from unstructured data on the web to highly structured data in relational database systems. Many research studies often focus on only one kind of data source, either unstructured or structured. However, as the complexity of data increases, we could no longer only analyze one source of data independent from others as we would then miss much information just like the blind men in the story. Motivated by this, my research goal is to holistically integrate and analyze heterogeneous data sources.

Audit Quality and Financial Performance of Companies Listed in Nairobi Securities Exchange

This study sought to establish the relationship between audit quality and financial performance of listed companies in Nairobi Securities Exchange. The specific objectives were: to examine the influence of size of the audit firm on the financial performance of listed companies in NSE, to determine the effect of auditors independence on the financial performance of listed companies in NSE, to establish the effect of attributes of the audit team on the financial performance of listed companies in NSE and to establish how the auditor’s experience influences financial performance of listed companies in NSE. The theoretical framework encompassed a review of the auditors’ theory of inspired confidence, agency theory and stakeholders’ theory. This study adopted a descriptive research design. The sampling frame of this study was drawn from directories of the Nairobi Securities Exchange Limited; consisting of all the 9 listed companies in Kenya. Data from the ICPAK indicate that there are a total of 826 CPAs working in the 9 listed companies in Kenya. The study used simple random sampling to select 89 respondents since the study population was homogenous. Both primary and secondary data was used. Piloting was carried out to test the validity and reliability of the instruments. To establish the validity of the research instruments the researcher sought the opinion of experts in the field of study. The study used Cronbach (Alpha – α) model to test the reliability of the data. Quantitative and qualitative data that was collected using questionnaires was inspected for errors and gaps. The data was then well examined and checked for completeness and comprehensibility. After inspection, the data was coded and analysed by the use of descriptive statistics using SPSS. Data was analysed by multiple linear regression analysis. Findings of the study indicate that the effect of audit quality on financial performance is positive and significant and the greater the degree of an auditors independence, the greater the propensity of a firm making substantial net profit margins. The impact of auditor size was also positive and significant, although, its impact was lesser that of auditor independence. It is recommended that the management of listed parastatals should employ the services of one of the big audit firms and where this is not possible, management should go for an audit firm whose character and integrity is beyond question. Due to the importance of having high quality audit, further studies should explore the areas that relate to audit quality such as customer service satisfaction, customer loyalty, auditors switching and auditors turnover. This will go along incorporating quality and independence of management and board membership; internal audit considerations.

Sparse Dictionaries for Continuous-Domain Inverse Problems

We study 1D continuous-domain inverse problems for multicomponent signals. The prior assumption on these signals is that each component is sparse in a different dictionary specified by a regularization operators. We introduce a hybrid regularization functional matched to such signals, and prove that corresponding continuous-domain inverse problems have hybrid spline solutions, i.e., they are sums of splines matched to the regularization operators. We then propose a B-splinebased exact discretization method to solve such problems algorithmically. The task in an inverse problem is to recover a signal s0 based on M measurements y ≈ ν(s0) ∈ R , where the measurement operator ν models the physics of the acquisition system (forward model). This is typically achieved by minimizing the distance between the data y and the measurements ν(s) of the reconstructed signal s (data fidelity). In order to inject some prior knowledge on the form of the signal, a regularization term is commonly added to the cost functional. In recent years, the advent of compressed sensing (CS) has led to an increasing popularity of sparsity-promoting regularization norms such as the `1 norm [1], [2] for discrete signals. Then, the prior assumption is that the signal s0 is sparse in a certain dictionary basis specified by a regularization operator. However, realworlds signals are typically composite and are thus not sparse in a single dictionary basis. We therefore focus on multicomponent signals s = s1+ . +sD , where each component sd is assumed to be sparse in a different dictionary basis. This framework is closely related to the data separation problem [2, Chapter 11], as well as the study of redundant dictionary bases [3]–[8]. This approach has been applied successfully in practice for imaging tasks such as morphological component analysis [9], [10] or image restauration [11]. These works dealing with multicomponent signals focus on purely discrete models. Yet many real-world signals are continuously defined, and this mismatch leads to discretization errors. This observation has lead to an abundance of research on continuous-domain problems with sparsity-promoting norms [12]–[15]. However, to the best of our knowledge, until our submitted work [16] that we present here, no such attempts have been made for multicomponent signals. We focus on generalized total-variation regularization (gTV) ‖f‖TV(N0) := ‖D {f}‖M = sup φ∈S(R) ‖φ‖∞=1 〈f,D0{φ}〉, (1) where D is the derivative operator and S(R) is the Schwartz space on R. It is known that gTV promotes sparsity in the sense that it leads to reconstructed signals that are sparse polynomial splines of order N0 [15]. A polynomial spline of order N0 can be expressed as s(x) = 1 (N0−1)! ∑ k ak(x− xk) N0−1 + + p(x) where ak, xk ∈ R and p is a polynomial of degree no greater than N0 − 1. The sparsity of a spline refers here to the number of knots xk. In order to deal with multicomponent signals, we introduce the This research was supported by the Swiss National Science Foundation, Grant 20002

Characteristic Velocity Distribution of Rectangular Duct Flow of a Magnetic Fluid under Magnetic Field

Velocity distribution of rectangular duct flow of a magnetic fluid was measured using Ultrasonic Velocity Profiling (UVP) method and influence of magnetic field on the velocity distribution was investigated. Velocity profile measurements have been performed in both laminar flow and turbulent flow and we paid attention to the effects of external magnetic field intensity ranging from 0 mT to 700 mT. As a result of the measurements, characteristic velocity distribution was obtained. In the case of laminar flow, when the magnetic field is applied to this magnetic fluid flow, the flow velocity at the center of the rectangular duct decreases and the velocity gradient in the near-wall region increases. On the contrary, in the case of turbulent flow, not only velocity gradient but also flow velocity near the center of the duct increases with applying magnetic field. This fact indicates that the characteristic anisotropy exist in the velocity distribution related to the magnetic field direction.
