Deradicalization Programs and Counter-Terrorism
No full textThe study of terrorism is important because terrorism poses a serious physical threat to the security of citizens and to the open society. Radicalization is a process through which people become increasingly motivated to use violent means against members of an out-group or symbolic targets to achieve behavioral change and political goals. De-radicalization is a process in which people reject the ideology they once embraced. Findings of study suggest that deradicalization comprises on multiple methods and techniques to fight against terrorism. Reduction of manpower is perceived the effective and sound strategy of deradicalization for eradicating terrorism. A successful deradicalization program potential eliminates the strength of terrorist organization. Ample of studies reveal that outcomes through deradicalization programs are not satisfactory worldwide and there is no scientific way to deal with radicalization. Successful deradicalization depends upon an understanding of radicalization itself. The reduction of manpower within terrorist or violent extremist organizations is one of the more important and one of the first effects that deradicalization programmes have on the fight against terrorism. Every deradicalization process that is completed without failure results in the elimination of one potential member of an extremist group in the years to come. World still lacks a national counter-radicalization policy that could serve as a holistic framework for the reintegration and rehabilitation of former militants. Hence all deradicalization projects must follow international best practices with full transparency
African Journal of Business Management Impact of Gender Diversity on Spiritual Leadership and Follower's Need for Spiritual Survival/Well-being
No full textGender diversity in organizations plays a very important role and greatly influences the leaders and followers behavior. The success of the organizations depends very much on its human resource team. The Leaders and followers play major role in any organizations. Due to this reason, the effect of gender related to leadership spirituality and follower's need for spiritual survival is taking a much attention among the researchers during the twenty-first century. A very few studies have been conducted by the researchers and have made some contributions on this topic in American and European context, but this area has been remained ignored by behavioral scholars in Pakistani context. The objective of this study is to examine the impact of gender on spiritual leader's behaviors and follower's need for spiritual survival/well-being. Therefore, this research aims at exploring the effect of gender diversity on leadership spirituality. The implications for practitioners and researchers have been discussed at the end of the study
Demonizing Africa: A Bend in the River and Naipaul’s Comprador Intellectuality
No full textThis paper establishes V.S. Naipaul’s position as a comprador intellectual for his essentialist representation of Africa in A Bend in the River. The position (of comprador intellectual) has been ascribed by Hamid Dabashi to the array of highly feted non-Western writers who justify the Western orientalist (mis)appropriation of the East. The unrelenting orientalist bashing of the imperialized world (Africa in this case) legitimizes the civilizational responsibility of the West to mend the situation of the supposedly inferior Africans. The violent colonial intervention to provide order and stability to the place shows Naipaul’s orientalist world view regarding the colonized Africans. The alleged, all-pervading darkness of Africans can thus be illuminated by the White colonizer’s masterful exercise of power. Naipaul, as an author, functions as a comprador intellectual who appears serving the colonial commercial interest. The West needs to destroy all the cultures that may be potential sites of resistance, so, Naipaul offers a systematic denigration of African culture to sabotage the potential culture of resistance. The narrative of African demonization justifies the colonial machinery and its exercise of violence against the natives. The paper, therefore, calls into question Naipaul’s role as a cultural intermediary, since his 'point of enunciation' (a concept given by Stuart Hall) seems to be resting on an overtly colonial trajectory of the West
Climate and Weather Condition of Balochistan Province, Pakistan
No full textThe study discusses the climate of Balochistan with a special focus on the variation of weather condition taking into account the mean monthly precipitation, temperature, humidity, atmospheric circulation, air pressure, evapotranspiration and solar energy covering the time duration of 1931-2020 (normal data). The physical barriers that bring variations in the climate of Balochistan contain geographical location, ocean, geomorphology, land use, natural vegetation, and continental extent. Based on precipitation, the province has been divided into two main regions that are arid and semi-arid, while the temperature zones are hot, warm, mild and cool. The southern and eastern part of the province receives heavy rain in the summers (monsoon), whereas it is from the western depressions during the winter season. Balochistan experiences four rainy seasons in winter (cold), pre-monsoon season (warm), monsoon season (hot), and post-monsoon season (mild). Owing to tropical (coastal) and sub-tropical continental characteristics, the area familiarizes two foremost seasons namely winter and summer. The summers of the area long for 5 months in hilly areas while 7 months in continental plains and coastal regions; whereas, winters cover five months in the plains and seven months in the mountains. Based on the appropriation and fluctuation in climate constituents, Balochistan has been classified into two main, 6 meso, and 9 microclimate and weather zones. According to Global Climate Risk Index, 2021, Pakistan has been ranked at 8th in the list of top ten global climate high-risk countries, which are exposed to the ongoing climate change and requires attention to resolve the issue
Modified physical properties of Ni doped ZnO NPs as potential photocatalyst and antibacterial agents
No full textHazardous organic dyes, present in the effluents of industries, are continuously polluting the environment. Photodegradation of these dyes on catalyst surface under sunlight irradiation is economic, safe and suitable strategy to protect environment. Hence, the synthesis and applications of Zn1-xNixO (x = 0.00, 0.02, 0.04, 0.06) NPs are reported here. Effect of pH and dopant concentration was studied to modify the electrical, magnetic, antibacterial and photocatalytic properties of Ni doped ZnO NPs. The samples were characterized by Scanning electron microscopy (SEM), Powder X-ray diffraction (XRD), UV–Visible spectroscopy (UV–Vis.), Energy-dispersive X-ray spectroscopy (EDS) and Fourier-transform infrared spectroscopy (FTIR) to determine the morphology, crystallite structure, optical properties, elemental composition and functional group detection, respectively. LCR meter and VSM were used to evaluate the dielectric properties and magnetic properties of Ni doped ZnO NPs, respectively. XRD pattern confirmed the presence of hexagonal wurtzite geometry of ZnO NPs. The structural and morphological analysis showed the increase in crystallinity with little effect on shape of doped NPs by increasing the dopant concentration and slight increase of pH. It was observed that the Ni doped ZnO NPs possess good photocatalytic potential by 94% degradation of 20 ppm solution of methyl orange dye (MO) in just 80 min under sunlight. Moreover, the enhancement in antibacterial potential was also observed with increase in dopant concentration and decrease in crystallite size of doped ZnO NPs. Smaller size NPs were found more effective against gram negative bacterial strains. © 2023 The Author(s)King Saud University, KSUAuthors would like to extend their sincere appreciation to the Researchers Supporting Project number (RSP2023R123), King Saud University, Riyadh, Saudi Arabia
Modelado y simulación de sistemas fotovoltaicos bajo condiciones de sombreado parcial
No full textgraficas, tablasThis thesis introduces a methodology for modeling commercial photovoltaic panels at the cell
level operating under partial shading conditions. In the first part, a review of the literature
is presented, focusing on the proper representation of the current-voltage characteristics in
both forward and reverse bias, the mathematical formulation, the circuit model, and the
estimation of parameters for photovoltaic cells.
In the second part, the single diode model (SDM), the direct-reverse model (DRM), and
Bishop’s model are introduced, emphasizing their current-voltage relationship, mathematical
formulation, circuit model, and parameter requirements.
In the third part of the thesis, a procedure to obtain I-V curves in panel terminals without
the need for any physical intervention is detailed. This procedure is necessary to compare
the behavior of the three models analyzed in both quadrants. The procedure requires a panel
without a bypass diode and measurement equipment capable of acquiring current, voltage,
temperature, and irradiation.
After considering the evaluation of some metrics such as root mean square error (RMSE)
and mean absolute percentage error (MAPE), Bishop’s model is selected for use in the
methodology.
In the fourth part, a methodology to estimate the parameters of Bishop’s model is proposed, which formulates the estimation of the parameters as an optimization problem. The metho-
dology uses a genetic algorithm, and it is validated using information from two commercial
panels. The curve reconstructions for each technology are evaluated using metrics such as
RMSE and MAPE to assess the accuracy of the models (Texto tomado de la fuente)Esta tesis presenta una metodología de modelado de paneles fotovoltaicos comerciales a nivel
