A survey of author name disambiguation techniques: 2010–2016
No full textAbstractDigital libraries content and quality of services are badly affected by the author name ambiguity problem in the citations and it is considered as one of the hardest problems faced by the digital library researchers. Several techniques have been proposed in the literature for the author name ambiguity problem. In this paper, we reviewed some recently presented author name disambiguation techniques and give some challenges and future research directions. We analyze the recent advancements in this field and classify these techniques into supervised, unsupervised, semi-supervised, graph-based and heuristic-based techniques according to their problem formulation that is mainly used for the author name disambiguation. A few surveys have been conducted to review different techniques for the author name disambiguation. These surveys highlighted only the methodology adopted for author name disambiguation but did not critically review their shortcomings. This survey provides a detailed review of author name disambiguation techniques available in the literature, makes a comparison of these techniques at an abstract level and discusses their limitations.</jats:p
Measuring microfinance access : building on existing cross-country data
Get PDFGiven the acknowledged need for a new effort to expand the set of available data on direct access to financial services, including a focus on access by those at low income, Honohan provides a selective review of the diverse sources of data that exist and considers how best to build on them. He proposes a basic framework within which to consider the analysis of the interesting questions: (1) How does access affect poverty and productivity? and (2) What hinders access? The author discusses existing and potential contribution of household and business user surveys, surveys of providers and their regulators, and surveys of experts, and assesses their relative strengths.Banks&Banking Reform,Environmental Economics&Policies,Health Economics&Finance,Poverty Assessment,Governance Indicators
Exploring pre-service teachers\u27 motivation for joining the teaching profession in Karachi, Pakistan
No full textTeacher recruitment and retention remains an important concern, as not many people make teaching a profession of choice, which results in teacher shortage. The teacher shortage worldwide has given mount to conduct studies on pre-service teachers\u27 motivations for joining teaching career. Therefore, this study aimed to investigate pre-service teachers\u27 motivation for joining the teaching profession and their perception about teaching. Furthermore, it explored the association between the motivational factors and the perception constructs. It also compared the pre-service teachers\u27 motivation across the selected demographic variables (i.e. prior qualification and achievement grades in higher secondary). Using a cross-sectional survey, Factors Influencing Teaching Choice (FIT-Choice) scale was directly administered to 220 pre-service teachers enrolled in B.Ed. (lions) programme in Karachi, which were recruited from six teacher education institutes. Results revealed that the pre-service teachers highly considered teaching a sacred profession which would help them to promote peace and harmony through teaching (religious motives). Further, the desire to influence the next generation by providing service to society was also an important factor for the pre-service teachers in joining the teaching profession (social utility value). On the other hand, they reported to choose teaching as a last resort career (fallback career). The pre-service teachers perceived teaching as highly demanding (task demand) with moderate return in salary and status (task return) and they exhibited a relatively higher level satisfaction with their choice of profession. A positive relationship was found between the intrinsic career value (r=0.62, p\u3c0.001) and perceived ability (r=0.61, p\u3c0.001) to satisfaction with choice. Contrarily, a negative association p\u3c0.01) was observed between the intrinsic career value and social dissuasion. Comparison across prior academic qualification revealed that the arts group preservice teachers were more intrinsically motivated (intrinsic career value) than their science group counterparts (p\u3c0.01). Further, the low achieving pre-service teachers reported to have more positive outlook for the teaching profession by scoring significantly higher on religious motive (p\u3c0.05), intrinsic career value (p\u3c0.001), social utility value (p\u3c 0.001), ability (p\u3c0.001) and personal utility value (p\u3c0.01) as compared to the high achievers. Interestingly, fallback career (p\u3c0.05) was relatively rated high by the pre-service teachers falling in the category of high achievers as compared to mediocre and low achievers. The study provides insights to the teacher educators for counselling their students about their future aspiration and opportunities pertaining to the field of teaching. The tool adapted can be a valuable addition to the contextual literature which can be used for similar studies
Uslub Dialogis Kisah Nabi Musa As. Dalam al-Qur’an
Get PDFThe Qur'an was revealed by Allah Swt. to the Prophet Muhammad Saw. in a very fluent language, Arabic with all its amazing characteristics. in the story of the Qur'an we find many verses that are dialogues between Allah Swt. and His messengers, between the apostles and his people, between pious people and others. And this conversation has a profound impact on the speaker as well as on the listener. In the revelation of God that the Qur'an there are many perfect stories, among the stories of the Qur'an which is very amazing and filled with mystery is the story and dialogue between the Prophet Moses with his people, the Prophet Moses with God, the Prophet Moses with Prophet Khidir and others. With the Balaghah Science approach, we can find that the words and dialogue of the Apostles can be used as guidelines and role models for us when communicating thoughts, ideas, intentions, feelings, and emotions directly in the world of education or for society. On this occasion the author will only examine the dialogue in the story of the Prophet Moses contained in the Qur'an with the aim to be more focused and not too long discussion. There is also a Balaghah qualitative research that specializes in Ma'ani knowledge, more precisely about Ijaz and Ithnab, with the hope of obtaining in-depth and detailed results. After the author conducted research on Ijaz and Ithnab in the conversation on the story of Moses in the Qur'an, the writer got several results, including that in the Qur'an there are 22 ijaz, 13 for ijaz qashr and 9 for ijazhadzfu. And there are 33 for ithnab, namely 3 for al-Idhahba'dal ibham (explanation after the unclear ones), 2 for dzikrul khas ba’dal ‘am(mentioning those that are specific after the general nature), 5 for tadzyil , 6 for takmil, 1 for tatmim, 5 for i'tiradh and 8 for tikrar. In the ijaz and ithnab there are many secrets, deep meanings, and enormous value. The purpose of ijaz and ithnab is to summarize, glorify, glorify, praise, criticize, strengthen meaning, explain meanings and others

The economic analysis of sector investment programs
Get PDFThis paper discusses the economic analysis of sector investment or expenditure programs, collectively referred to as SIPS. There are many different views as to what actually constitutes a SIP. For the purposes of this paper, the essential feature of a SIP that is focused on is that the Government, World Bank, and other donors jointly finance an agreed-upon forward sectoral expenditure program. A SIP may also have many different objectives. Again, for the purposes of this paper, a critical objective of a SIP is to improve the development impact of public expenditures in the sector. Suthiwart-Narueput focuses on how to use economic analysis to help sector investment programs improve the development impact of public spending. He uses Kenya as a case study. The paper is organized as follows. Section 2 proposes a methodology for the economic analysis of SIPS which emphasizes evaluating the sectoral expenditure program based on principles of public expenditure analysis. Particular emphasis is placed on identifying the rationale for public intervention and improving cost-recovery. Section 3 discusses alternative methodologies, e.g., cost-benefit analysis. Section 4 applies the proposed methodology to the Kenya Agricultural SIP. Section 5 concludes.Business Environment,Environmental Economics&Policies,Health Economics&Finance,Decentralization,Economic Theory&Research,Environmental Economics&Policies,Business in Development,Business Environment,Health Economics&Finance,Poverty Assessment
Inter-Varietal Variation in Phenolic Profile, Antioxidant, Anti-Inflammatory and Analgesic Activities of Two Brassica rapa Varieties: Influence on Pro-Inflammatory Mediators
Get PDFThe present research study aims to appraise the potential of polyphenol-rich extracts from two Brassica rapa varieties on antioxidant, anti-inflammatory and analgesic activities using carrageenan-induced paw edema model in rats. Methanol extracts of peels and pulps of Brassica rapa yellow root (BRYR) and Brassica rapa white root (BRWR) were prepared using the soxhlet extraction technique. All four extracts were analyzed by reversed-phase high-pressure liquid chromatography (RP-HPLC) for the polyphenols, and results showed that 10 phenolic acids and 4 flavonoids were detected. Gallic acid was the major phenolic acid (174.6–642.3 mg/100 g of dry plant material) while catechin was the major (34.45–358.5 mg/100 g of dry plant material) flavonoid detected in the extracts. The total phenolic contents (TPC) of BRYR peel, BRWR peel, BRYR pulp and BRWR pulp extracts were in the range of 1.21–5.01 mg/g of dry plant material, measured as GAE, whereas the total flavonoid contents (TFC) were found in the range of 0.90–3.95 mg/g of dry plant material, measured as QE. BRYR peel extract exhibited the best DPPH radical scavenging activity (IC50, 3.85 µg/mL) and reducing potential as compared with other extracts. The in vivo anti-inflammatory potential was assessed by carrageenan-induced rat paw edema, and the analgesic potential was investigated by a hot plate test. Suppression of biochemical inflammatory biomarkers including C-reactive protein (CRP), rheumatoid factor (RF) and tumor necrosis factor (TNF-α), and interleukin-6 (IL-6) concentration were also determined. Results showed that BRYR peel extracts reduced paw edema and suppressed the production of TNF-α, IL-6, CRP and RF most significantly, followed by BRWR peel, BRYR pulp and BRWR pulp extracts. In addition, histopathology observation also supports the anti-inflammatory effect of peel extracts as being greater than that of root pulp extracts. Moreover, it was observed that the analgesic effect of the root-peel extracts was also more pronounced as compared with root-pulp extracts. It can be concluded that BRYR peel extract has higher phenolic contents and showed higher suppression of TNF-α, IL-6, CRP and RF, with strong antioxidant, anti-inflammatory and analgesic effects.This research was funded by Qatar University
Development of a Game to Encourage Data sharing in Supply Chain
No full textIn order to tackle the problem of supply chain managers not being ready to share data, the thesis first identifies the root causes of the reluctance of supply chain managers towards sharing data. This reluctance of the supply chain managers is caused by many reasons. Firstly, they fear the misuse of their sensitive information. Information regarding one supply chain firm can be used by other firms in a way that undermines the original firm. The competitors can use this information to win the race over the original firm. There is not enough trust between supply chain firms and hence, they fear giving their information to each other. Lastly, the data sharing techniques would require investment in terms of infrastructure of data sharing technologies. The reluctance, caused by the aforementioned reasons, is a reason for the absence of data sharing in supply chains. By overcoming this reluctance and sharing data in a supply chain, efficiencies can be increased and optimal potentials can be achieved. Therefore, this reluctance is an obstacle that needs to be overcome.Management of Technology (MoT
Visual Heritage Recast: The Crescent Motif in 21st-Century Logo Design
Get PDFThis research explores the visual and symbolic significance of the crescent icon in modern logo design. Traditionally associated with cultural, spiritual, and celestial meanings, the crescent has evolved into a widely recognized design element across corporate and institutional branding. The study investigates why contemporary organizations adopt the crescent form, how audiences interpret it, and why some institutions modify or flip its traditional orientation. Through semiotic and visual analysis of selected global and regional logos, the paper reveals that the crescent shape conveys ideas of growth, renewal, inclusivity, and forward movement. The flipped or stylized crescent, meanwhile, reflects design modernity, cultural neutrality, and an effort to appeal to global audiences. The findings contribute to design scholarship by connecting symbolic heritage with contemporary branding practices.

Strategic Reforms for Accelerated Agricultural Growth in Pakistan
Get PDFAgricultural growth rates in the 1960s, 1970s, 1980s and 1990s show that strong growth during the 1960s was driven by several factors, including greater certainty in the use of irrigation water (as a result of an agreement with India), the introduction of productivityenhancing fertiliser-seed packages, the introduction of tubewells and the electrification of rural areas, and policy changes that improved the profitability of farming. Growth during the 1970s dropped to 2.3 percent as a result of the uncertainty created by land reforms in 1972 and 1977, severe climatic shocks, a cotton virus that depressed production for most of the decade, and political instability. The recovery in the 1980s and early 1990s can be attributed to the introduction of new cotton varieties and improved management techniques, as well as to a gradual improvement in economic incentives. Closer inspection of the nature and sources of this growth raises concerns about its sustainability and casts doubt on the ability of the sector to grow by more than 3–4 percent a year in the future. Many of the past sources of agricultural growth in Pakistan appear to have been fully exploited. Strategy for the future must effectively address the followings. Allowing the market to Operate, policy reforms that support the ongoing structural adjustment should be given top priority. To address the crisis in irrigation management market-determined incentives must be allowed to determine resource allocation within the irrigation system. Reform in extension should include establishing closer links with research institutions and reducing the number of front-line extension workers and replacing them with fewer, bettertrained workers who are more responsive to the needs of farming systems. Full-fledged land reform is difficult to enact and can be considered only after a comprehensive study of costs and benefits. Some important measures can be implemented immediately, however. Foremost is providing security of tenure to many farmers, especially tenants-at-will, thereby improving responsiveness to incentives and creating better incentives for long-term investments.
