AbstractIn this paper, we consider a wireless powered cognitive relaying system with a secondary relay (SR) capable of harvesting wireless energy. Along with an access point (AP) continuously transmitting the primary data to a primary user (PU), a secondary source (SS) can transmit the secondary data to a secondary destination (SD) with the help of SR using the decode-and-forward (DF) protocol. SR can harvest energy from both SS and AP in both time and power domains using time-splitting and power-splitting techniques. The interference from primary data transmissions can help boost the amount of harvested energy at SR. The transmit power of SS is regulated by the interference threshold at PU and the allowable peak power. Despite the above two constraints, the transmit power of SR is further constrained by the amount of harvested energy. Once SR successfully decodes the data from SS, it will forward the data to SD using a constrained power. We analyze the approximate outage probabilities for both primary and secondary systems. Simulation results are provided to verify the effectiveness of our theoretical analysis and reveal the impacts of various parameters to the outage performance.

This study attempted to explore the process of word formation and its social function of slang words on Rich Brian's official music video, precisely in the comment section of the newest song of him, D.O.A that released on 25 August 2020. This study employed discourse and sociolinguistics aspects; hence, this study's research design was a descriptive qualitative. Additionally, this study's object was a one-month comment section of Rich Brian's newest song official music video. Furthermore, there were two sources of data, primary and secondary data sources. The primary data were a comment section of Rich Brian's newest official song music video, while the secondary source was from available works of literature and urban dictionary. Therefore, to collect the data, this study did the documentation from the D.O.A. official music video from one-month duration comments. As the data obtained, there were 49 slang words found. Then, they were analyzed through Yule (2010)�s theory as the basis of word formation process standard, while Zhou & Fan (2013)�s theory was used as the basis of word formation function standard. Data analysis is divided into several steps: reading, collecting, classifying, and analyzing the data. The result showed that derivation was the highest frequency of the word-formation process. It was 22%, the acronym was 18%, coinage was 16%, the conversion was 14%, blending was 12%, compounding was 8%, clipping was 6%, borrowing and multiple processes were 2% of each. Besides, the highest social function was to express emotive feeling with 49 % quantity of the frequency. The second higher was to pursue self-identity, achieving politeness was 8%. This study suggested a more in-depth analysis of non-standard languages, such as swear words or taboo words and emoticon that can be done through a social semiotic approach.

Relaying Protocols

In this paper, we propose and evaluate performance of multihop multipath underlay cognitive radio networks. In a primary network, an uplink nonorthogonal multiple access method is employed to allow primary transmitters to simultaneously transmit their data to a primary receiver. Using an underlay spectrum-sharing method, secondary source and secondary relays must adjust their transmit power to guarantee quality of service of the primary network. Under the limited transmit power, cochannel interference from the primary transmitters, and hardware noises caused by impairments, we propose best-path selection methods to improve the end-to-end performance for the secondary network. Moreover, both multihop decode-and-forward and amplify-and-forward relaying protocols are considered in this paper. We derive expressions of outage probability for the primary and secondary networks and propose an efficient method to calculate the transmit power of the secondary transmitters. Then, computer simulations employing the Monte-Carlo approach are realized to validate the derivations.

In this paper, we investigate the outage performance of simultaneous wireless information and power transfer (SWIPT) based Decode-and-Forward (DF) relay networks, where the relay needs to simultaneously forward information for two relaying links, primary relaying link and parasitic relaying link. The primary relaying link is the traditional source-relay-destination relay system. While in the parasitic relaying link, the parasitic source, i.e., Internet-of-Things (IoT) tag, is not connected to the stable power source and thus has to backscatter the signals from the primary source to convey its information. The relay not only harvests energy from Radio Frequency (RF) signals from both sources but also forwards messages to their corresponding destinations. The primary source and destination are unaware of the parasitic backscatter transmission, but the relay and parasitic destination can employ successive interference cancellation (SIC) detector to eliminate the interference from the primary link and detect the message from the parasitic source. In order to investigate the interplay between the primary and parasitic relaying links, the outage probabilities of both relaying links are derived. Besides, the effects of system parameters, i.e., power splitting coefficient, forwarding power allocation coefficient and backscatter reflection coefficient, on the system performance are discussed. Simulation results verify our theoretical analysis. In the meanwhile, it is revealed that the advised relaying system has far larger sum throughput than the one with only primary relaying link and the parasitic relaying link can gain considerable throughput at the cost of negligible degradation of primary throughput.

Data were collected from seven fish markets of Barisal, southern Bangladesh including Port road fish market, Taltoli bazar fish market, Chaumatha fish market, Notullabad bus stand fish market, Kasipur bazar fish market and Bazar road fish market. Both primary and secondary data were used during 1 year study period from May, 2011 to April, 2012. Primary data were collected through field surveys and pre-structured questionnaire was used for interviewing of 10 organizers, 20 aratdars (commission agent), 50 fish traders and 100 consumers. Secondary source of information consists of published materials such as journals, textbooks, newspapers and also from interviewing different government and non-government officials and members of various fisheries related cooperative societies. The results of this study revealed 11 fish marketing channels in Barisal city’s fish marketing system. The average marketing cost ranged from 4.15% to 8.33% (6.76±0.98) % of the final retail price. The highest and lowest average fish price were recorded as USD 7.07/kg and USD 1.03/kg for giant fresh water prawn and silver carp, correspondingly. Intermediaries’ marketing margin on different species’ marketing fluctuated from 29.6% to 50.28% (39.38±5.22) % for silver carp and brown shrimp marketing, respectively. Establishment of modern fish landing center and retail markets near the fish landing port, introduction of government fish shops and  insulated and refrigerated fish vans and fish carriers, training of all personnel related to fish marketing about fish handling, quality of fish, hygiene practices, improvement of existing fish market structure, provision for government and private funding assistance for fishers/fish farmer, formulation and enactment of independent act/ordinance for fish landing and marketing are highly recommended. DOI: http://dx.doi.org/10.3126/on.v12i1.12254Our Nature (2014), 12(1): 28-36

 Objective: To assess the corporate social responsibility practices in Nepalese commercial banking sector. Methods and Materials: Primary and secondary sources of data were used in the study. The primary data were collected through direct questionnaire method from 60 employees of sampled commercial banks. The secondary source was through journals, textbooks and annual reports of Nepal Rastra Bank. SPSS and Microsoft excel were used to analyze the collected data. The value of Cronbach’s Alpha (α) of overall questionnaire is 0.92, which suggests the reliability of primary data. Descriptive and explorative research designs were used to analyze the primary and secondary data. Results and Conclusion: Responses from all the respondents of commercial banks regarding CSR and Non-Financial Performance clearly imply that CSR has an influence on the Non-Financial Performance. In terms of ‘R2’, CSR impacts both Brand Image and Brand Awareness (i.e. 0.987). This clearly indicates that more than 98.7% variance of both non-financial performances has been explained by CSR. In terms of ‘R2’, CSR impacts less in financial performance (i.e. 0.149). This clearly indicates that only than 14.9% variance of financial performance has been explained by CSR.
