ABSTRACT

The different dimensions of spiritual health among older adults remain unknown to date and no globally acceptable definitions have yet been provided for the concept. To conduct the current study, the databases including Proquest, Medline, CINAHL, Science Direct, Blackwell, Iranmedex, SID, Noor Magazine and Irandoc were searched for the articles published between 1980 and 2014 in both English and Persian using keywords including spirituality, spiritual well-being, spiritual health, geriatric, older adult and old people and their Persian equivalents. The search for articles yielded into 197 titles, 31 of which were repeated and were therefore excluded. The remaining 166 articles were screened based on the inclusion criteria. A total of 29 articles were ultimately selected as the study samples. Rodgers’ evolutionary approach to concept analysis is used to identify the attributes, antecedents, consequences and surrogate terms of “spiritual health” and to provide a more comprehensive definition of the concept. The results obtained showed that spiritual health from the perspective of older adults is a multi-dimensional concept with cognitive, functional, affective and consequential components. Each component was found to be composed of several indicators. The results may help in providing a more thorough definition of spiritual health which can be a solid base for future researchers to develop appropriate tools for the assessment of older adults’ spiritual health and encourage research into this partially neglected subject. Care providers may also benefit from the results through acquiring a better understanding of the concept which can be used in designing appropriate spiritual interventions.  相似文献

Adaptive threshold to guarantee both detection and false alarm probabilities in multi-taper based spectrum sensing     

Emad S. Hassan 《Journal of The Franklin Institute》2019,356(3):1640-1657

The multi-taper spectrum (MTS) estimator enjoys a relatively low computational complexity and high estimation accuracy making it an attractive method for spectrum sensing in cognitive radio (CR) networks. However, it is difficult to guarantee both detection and false alarm probabilities when its design is based on fixed threshold, especially when the noise power fluctuates due to channel conditions. In this paper, a new adaptive threshold method to guarantee both detection and false alarm probabilities for MTS based spectrum sensing is proposed. By means of estimating noise power and signal power, the decision of adaptive threshold is able to adapt the noise fluctuation and achieve efficient trade-off between detection and false alarm probabilities. A closed form expression for the adaptive threshold is derived for both additive white Gaussian noise (AWGN) channel and multipath fading channel. Several metrics are employed to compare the performance of the proposed adaptive threshold method with that of the fixed threshold methods such as: error decision probability, detection probability, false alarm probability and throughput. The obtained results show that the proposed method achieves better spectrum efficiency and high throughput in comparison with the conventional fixed and adaptive threshold methods presented in the literature.  相似文献   

A new approach for constrained chaos synchronization with application to secure data communication     

Mohamed F. Hassan  Mohammad Hammuda 《Journal of The Franklin Institute》2019,356(12):6697-6723

In this paper, a new technique is introduced for chaos secure data communication. In this approach, in addition to the usually used techniques for data encryption, the concept of carrier encryption is introduced to increase the security level of the secure communication scheme. To fulfill this objective, at the transmitting end, two chaotic oscillators are coupled, and a set of inequality time dependent constraints with time dependent bounds is imposed on the generated chaotic signals. Moreover, to increase system complexity and its security level, the imposed set of constraints and their bounds are allowed to be changeable from one time period to another during the transmission process. As a result, the patterns of the generated chaotic signals are completely changed and the chaotic oscillator is completely encrypted. At the receiving end, the newly developed Constrained Smoothed Regularized Least Square (CSRLS) observer is used to synchronize the received constrained chaotic signals and hence retrieve the transmitted data. Using such an approach, the quality of the received information, measured by the Bit Error Rate (BER), is highly improved due to the superior performance of the developed CSRLS observer. The stability of the observer is analyzed, and simulation results are presented to show the efficiency and effectiveness of the proposed secure communication scheme.  相似文献

Carboplatin is a chemotherapeutic agent used against various malignancies such as ovarian carcinoma. The aim of this study is to improve the therapeutic efficacy of carboplatin using pegylated liposomal nanocarriers. Nanoparticles were synthesized using thin film hydration technique and characterized for shape morphology, particle size, zeta potential and drug-release properties. In the next step, A2780S and A2780CP ovarian cancer cell lines were used to determine the efficacy of nanodrug by MTT assay. The particle size and zeta potential of nanodrug were measured 244.3 ± 19.6 nm and ?22.9 ± 1.7 mV, respectively. High encapsulation capacity (78.6 ± 3.7 %) confirmed the efficiency of technique. The cytotoxicity results also showed that nanodrug compared to free drug improve the efficacy of carboplatin against both A2780S (P < 0.01) and A2780CP (P < 0.05) cell lines. In conclusion, the findings of our study suggested pegylated liposomal nanocarriers are proper for carboplatin delivery to ovarian cancer cell lines A2780S and A2780CP.  相似文献   

A different result of community participation in education: an Indonesian case study of parental participation in public primary schools   总被引：1，自引：0，他引：1

Parental participation in school management is regarded as a good thing according to the rationale that local people know better and are able to be more responsive to their own needs. However, little is understood about the implications of the School Operational Support policy for community participation in education. This study investigated parental participation in the context of education decentralisation with regard to the changing situation in which the Indonesian government provides sufficient funds for school operational costs. Using a qualitative inquiry, researchers collected data through document analyses, questionnaires and interviews with stakeholders of two public primary schools in Depok, Indonesia. The study found that prior to the Free School Program, parental participation was limited to parents’ financial contribution and associated matters. However, since school was made free, parents’ involvement in school budgeting has become very limited; they are no longer engaged in the planning of allocations, and neither they nor the school committees are able to make inputs into decision making; even the functions of the school committees are limited to rubber stamping the school budget.  相似文献   

The use of lysosomal enzymuria in the early detection and monitoring of the progression of diabetic nephropathy     

Donatien Gatsing  Ibrahim Hassan Garba  Godwin I. Adoga 《Indian journal of clinical biochemistry : IJCB》2006,21(2):42-48

Recent acquisitions on the early detection and monitoring of the progression of diabetic complications (nephropathy) using the techniques of enzymology (lysosomal enzymes) are reviewed. it appears that the kidney is the principal source of urinary lysosomal enzymes. Urinary samples for lysosomal enzyme determination can be either 24-hour or spot-collection. The use of synthetic substrates (4-methylumbelliferyl substrates) provides an easy, inexpensive, sensitive and highly reproducible method of lysosomal enzyme assay. It is recommended that more than one enzyme be assayed in the process. The use of fractional enzyme excretion (FEE) ratios is further recommended. The urinary lysosomal glycosidases investigated and found to be of particular diagnostic value in the early detection of diabetic nephropathy include N-acetyl-β-D-glucosaminidase (β-hexosaminidase, NAG), β-glucuronidase and β-galactosidase, with NAG being the most useful indicator. Urinary NAG can be used in monitoring the progression of diabetic nephropathy. The fluorimetric assay of lysosomal glycosidases is particuarly recommended in developing countries since it is simple, sensitive and inexpensive.  相似文献   

Inhibitory control,dyadic social behavior,and mental health difficulties in preschoolers     

Raha Hassan  Louis A. Schmidt 《Child development》2022,93(3):e251-e265

Although inhibitory control is typically associated with positive outcomes, several theoretical frameworks suggest that too little and too much inhibitory control may be problematic. Using a longitudinal, latent variable approach, we examined whether a multi-method index of inhibitory control at Time 1 (N = 105, 52 girls, M_age = 3.50 years, 87% White) predicted observed social behavior with an unfamiliar peer and maternal report of preschoolers’ mental health difficulties at Time 2 (M_age = 4.76 years). Data collection occurred between 2017 and 2019. Inhibitory control displayed a U-shaped relation with prospective outcomes, where high and low levels of inhibitory control were associated with higher levels of avoidant social behaviors and mental health difficulties. The results are discussed in the context of under- and over-regulation in understanding individual differences in children's social behavior and mental health difficulties.  相似文献   

‘They're not girly girls’: an exploration of quantitative and qualitative data on engineering and gender in higher education   总被引：1，自引：1，他引：0  

S. Barnard  T. Hassan  B. Bagilhole  A. Dainty 《European Journal of Engineering Education》2012,37(2):193-204

Despite sustained efforts to promote engineering careers to young women, it remains the most male-dominated academic discipline in Europe. This paper will provide an overview of UK data and research on women in engineering higher education, within the context of Europe. Comparisons between data from European countries representing various regions of Europe will highlight key differences and similarities between these nations in terms of women in engineering. Also, drawing on qualitative research the paper will explore UK students’ experiences of gender, with a particular focus on the decision to study engineering and their experiences in higher education.  相似文献   

Expectations,realizations, and approval of tablet computers in an educational setting     

Mamdouh Hassan  Benny Geys 《Journal of Educational Change》2016,17(2):171-190

The introduction of new technologies in classrooms is often thought to offer great potential for advancing learning. In this article, we investigate the relationship between such expectations and the post-implementation evaluation of a new technology in an educational setting. Building on psychological research, we argue that (1) high expectations (ex ante) can undermine the approval ratings of new technologies (ex post); and (2) individuals’ post-implementation evaluations are more likely to exceed their expectations when they can exert power over the introduction of a new technology. We test these predictions on a sample of 750 respondents from primary and secondary schools in Flanders with and without tablet computers. Our findings are supportive of both theoretical predictions.  相似文献
