Near-capacity iterative decoding of binary self-concatenated codes using soft decision demapping and 3-D EXIT charts
Full text linkIn this paper 3-D Extrinsic Information Transfer (EXIT) charts are used to design binary Self-Concatenated Convolutional Codes employing Iterative Decoding (SECCC-ID), exchanging extrinsic information with the soft-decision demapper to approach the channel capacity. Recursive Systematic Convolutional (RSC) codes are selected as constituent codes, an interleaver is used for randomising the extrinsic information exchange of the constituent codes, while a puncturer helps to increase the achievable bandwidth efficiency. The convergence behaviour of the decoder is analysed with the aid of bit-based 3-D EXIT charts, for accurately calculating the operating EbN0 threshold, especially when SP based soft demapper is employed. Finally, we propose an attractive system configuration, which is capable of operating within about 1 dB from the channel capacity
نگاھی بہ ریاض الملوک: A Glance at Riaz-ul-Maluk
No full textThe historian and poet Muhammad Ghaus s/o Muhammad Faiq Qutb Shahi Pishawari belonged to the era of Ahmad Shah Abdali and was one of his countriers. He was also a teacher and trainer of Prince Taimoor Two of lus works discovered are "Diwan" (Collection of poetry) and "Riaz-ul-Maluk" "Riaz-ul- Maluk" is comprised of a preamble, two elegies/ accounts and a conclusion. In the preamble, the writer shares purpose of writing the book, in which he says that he wrote the book on the demand of attorneys of the court, who told him to pen down accounts of the life of kings and chiefs and offer them some words of counsel and then present the book to the king, so that he might use the book for his benefit during his leisure times. In the first eleg/account, the writer mentions life of kings. And in the second elegy/ account, he mentions life of other people than king
Pioneers of Library Movement in Pakistan
Full text linkThe paper aims to describe in brief the contribution of seven leaders of Pakistan librarianship, viz. K.B. Khalifa M. Asadullah, Prof. Dr. Abdul Moid, Dr. Abdus Subuh Qasimi, Muhammad Shafi, Fazal Elahi, Khawaja Nur Elahi and S. V. Hussain. The early library developments are given for better understanding of the role of these leaders
Distributed Self-Concatenated Codes for Low-Complexity Power-Efficient Cooperative Communication
Full text linkPursuing sustainability development goals through adopting gender equality: women representation in leadership positions of emerging market multinationals
No full textThis study examines the competitive disadvantages rationale behind the pursuing of Sustainability Development Goals (SDGs) by emerging market multinational corporations (EM-MNCs) in foreign markets. We argue that EM-MNCs may pursue gender equality goal in host markets as a legitimation strategy to offset their strategic disadvantages inherited from the home markets. Based on a sample of foreign subsidiaries from 10 major emerging countries from 2010 to 2020, this study finds strong evidence demonstrating that the institutional quality of home markets exerts a positive effect on the representation of women in leadership positions of EM-MNCs. Additional analyses demonstrate that international experience and institutional ownership further magnify this effect
Distributed Self-Concatenated Coding for Cooperative Communication
No full textIn this paper, we propose a power-efficient distributed binary self-concatenated coding scheme using iterative decoding (DSECCC-ID) for cooperative communications. The DSECCC-ID scheme is designed with the aid of binary extrinsic information transfer (EXIT) charts. The source node transmits self-concatenated convolutional coded (SECCC) symbols to both the relay and destination nodes during the first transmission period. The relay performs SECCC-ID decoding, where it mayor may not encounter decoding errors. It then reencodes the information bits using a recursive systematic convolutional (RSC) code during the second transmission period. The resultant symbols transmitted from the source and relay nodes can be viewed as the coded symbols of a three-component parallel concatenated encoder. At the destination node, three-component DSECCC-ID decoding is performed. The EXIT chart gives us an insight into operation of the distributed coding scheme, which enables us to significantly reduce the transmit power by about 3.3 dB in signal-to-noise ratio (SNR) terms, as compared with a noncooperative SECCC-ID scheme at a bit error rate (BER) of 10-5. Finally, the proposed system is capable of performing within about 1.5 dB from the two-hop relay-aided network’s capacity at a BER of 10-5 , even if there may be decoding errors at the relay
Institutional voids, liability of origin, and presence of women in TMT of emerging market multinationals
No full textThis study examines the association between the pervasiveness of institutional voids in emerging markets and the inclusion of women in top management teams (TMTs) by emerging market multinational corporations (EMNCs) as a legitimation strategy. Leveraging institutional theory, we argue that EMNCs increase women presence in TMTs as a legitimation strategy to overcome the challenges of stakeholders' skepticism in foreign markets by disassociating themselves from the image of their home markets. Using a subsidiary level dataset of 1047 EMNCs from 26 emerging countries between 2009 and 2018, we find robust evidence indicating that the pervasiveness of institutional voids at home is positively related to the percentage of women in TMT's EMNCs' foreign units. This effect is particularly stronger for firms operating in countries with high institutional gender parity and low level of corruption
Factors Influencing Students' Learning at KASB Institute of Technology
Full text linkThe research article looks into the psychological and other characteristics that play a role in students’ learning ability. In all the observations we have found some students performing better than the others, this display of performance in their studies implies the presence of certain factors which are different from others or play a role in their better learning capabilities. These factors may be present in students, teachers, institutions and others. This article is an attempt to highlight those factors which may be required on part of the students, teachers, institutions and others that may or may not play a significant role in enhancing students’ learning capabilities, the sample of 103 is used to infer the significance of these factors. Through research we were able to answer as per students, punctuality of the teacher is somewhat important in enhancing learning. Clarity of speech was considered an insignificant feature. The most preferred quality of the teacher which is responsible for ranking a teacher as the best teacher is cooperativeness. Another finding was the relationship between CGPA obtained and consulting teacher outside class, which we concluded that there is a strong relationship between consulting teacher and obtaining good CGPA. Lastly we found that time spend in library has no significant association with understanding of topic when taught.Students’ Learning, Students and Teacher Characteristics
Global insights on TMT gender diversity in controversial industries: a legitimacy perspective
No full textFirms in controversial industries such as tobacco, alcohol, gambling, weapon, and nuclear power suffer organizational legitimacy problems. These firms, therefore, adopt various strategies to acquire legitimacy. Drawing on institutional theory, we conceptualize the top management team (TMT) gender diversity as a legitimacy-seeking strategy and examines how a firm’s belonging to a controversial sector affects TMT gender diversity. Based on a cross-country sample of 1542 firms operating in controversial industries from 34 countries and control sample with another set of 1542 similar-sized firms from non-controversial industries, the empirical evidence shows that belonging to a controversial industry exerts a positive impact on TMT gender diversity. The effect of industry belonging on TMT gender diversity is positively moderated by institutional gender parity and a low level of corruption. It indicates that institutional factors act as emancipative forces that foster women's empowerment. Taken together, our results for moderating variables highlight the role of institutional characteristics in supporting women empowerment initiatives
