A Dynamic and Adaptive Information Security Awareness (DAISA) Approach
No full textInformation systems fail not only because of problems with technology used and technical incompetence of professionals administering them but also because of lack of security awareness to the end users. In addition, various research results have revealed that security and reliability of IS/IT systems is a function of technology, processes and people. This research has focused on the latter aiming at developing an integrated information security education, training and awareness learning continuum. Particularly, the research has focused on developing countries where a little has been done to address information security learning continuum. The research has been done in two cyclic phases in which cycle one has chiefly addressed security education and training aspects whereas cycle two has mainly focused on security awareness aspects. Based on empirical analysis of security practices in organisations; the thesis proposes a Dynamic and Adaptive Information Security Awareness (DAISA) approach. Founded on six interdependent pillars, the approach delineates high level guidelines for establishing and maintaining information security awareness programs at workplaces
Promoting information systems interoperability in enhancing compliance with maritime transport rules and regulations in Tanzania
Get PDFThis study was conducted to investigate how information systems interoperability can enhance maritime transport compliance monitoring and evaluation in Tanzania, specifically to identify the challenges posed by non-interoperable information systems and to investigate the barriers to achieving interoperability in maritime transport compliance monitoring and evaluation. The Responsive Regulation Theory and the Socio-Economic Theory of Regulatory Compliance guided this research. The study employed a convergent or concurrent design using a mixed-methods approach (qualitative and quantitative research approaches). Simple random sampling was utilized to select 171 respondents using Yamane’s formula for the quantitative component and eleven (11) participants through the purposive sampling technique for the qualitative component. The population comprised 300 individuals from Tanzania Shipping Agencies Corporation (TASAC) as the maritime transport regulator authority and regulated entities, from which, out of the 171 questionnaires issued, 160 were returned, resulting in a response rate of 93 percent, and based on data saturation and consultation with experts, in-depth semi-structured interviews with eleven (11) TASAC employees and compliance officers from regulated entities were used to collect qualitative data. Data were collected through questionnaires, interviews, and document analysis and analyzed using thematic analysis, descriptive analysis, and inferential analysis through ordered logistic regression. Delays in data retrieval, inconsistencies and inaccuracies across information sources, and inefficiencies in compliance reporting are among the critical challenges identified due to non-interoperable information systems. Furthermore, barriers such as information security risks, institutional information system fragmentation, and a lack of harmonized standards were found to significantly hinder the achievement of interoperability. The findings provide valuable insights for the Tanzania Maritime Regulatory Authority (TASAC), policymakers, and industry stakeholders on the need to have collaborative efforts for fostering secure, transparent, and efficient maritime operations through regulatory frameworks alignment, standardizing reporting procedures, integrating platforms such as the National Maritime Single Window (NMSW) and the Port Community System (PCS), and making governance structures more effective to ensure accountability and sustainability. By establishing an interconnected and secure digital environment, compliance monitoring and evaluation can become more efficient, transparent, and reliable
Evaluating the Efficacy of the E-Immigration System in the Provision of Immigration Services in Tanzania
Get PDFIn 2017, the Tanzania Immigration Services Department (TISD) launched the e-immigration system to streamline service delivery, minimize processing times, enhance customer satisfaction, and strengthen security measures. This study assesses the effectiveness of the e-immigration system in Tanzania, with a particular focus on its impact on service delivery and areas for improvement to enhance the customer experience. Conducted at the Kurasini Immigration Office and Julius Nyerere International Airport in Dar es Salaam, the research employed a mixed-methods approach, integrating quantitative and qualitative techniques. A sample of 247 participants was selected through a combination of purposive non-probability and randomized probability sampling methods. Data collection tools included structured questionnaires, direct observation, and semi-structured interviews. The gathered data were analyzed using SPSS and Microsoft Excel to generate statistical descriptions for interpretation and presentation of findings. The study uncovered significant challenges limiting the system\u27s effectiveness, such as unstable internet connections, unreliable system performance, inadequate infrastructure, and insufficient training for staff. Additional obstacles included concerns about data security, lack of feedback mechanisms, infrequent system updates, and accessibility issues. The research proposed enhancing the user interface to improve accessibility and usability and recommended that the government invest in comprehensive training programs for immigration officers to ensure they can effectively operate the system and deliver high-quality services to users
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Assessing the effectiveness of integrated information management system for managing land in Tanzania
Get PDFThis study assesses the effectiveness of the Integrated Land Management Information System (ILMIS) in Tanzania, focusing on whether it has achieved its intended objectives based on stakeholders’ perceptions. The Unified Theory of Acceptance and Use of Technology is used to assess the effectiveness of the system. A mixed methods approach is employed, using a convergent research design and stratified random sampling. The study is conducted in the Dar es Salaam City Council with the target population of 384. However, the study managed to collect data from 350 respondents, including land officers, surveyors, administrators, and community members. Data collection methods include structured questionnaires, interviews, and document reviews. Quantitative data are analyzed using descriptive and inferential statistics via SPSS, while qualitative data are examined through content analysis using Taguette software. The findings reveal that ILMIS significantly aligns with its intended goals in areas where it is fully implemented. Key achievements include the reduction of land disputes, improved accuracy of ownership records, and enhanced monitoring of illegal encroachments. The system has also improved service delivery by reducing transaction times and bureaucratic delays, thereby helping to curb corruption. Furthermore, ILMIS’s integration with other government functions, such as tax administration, reflects adherence to global best practices in land governance. This study concludes that ILMIS has a positive impact on land administration in Tanzania. However, for sustained success, the system requires continuous upgrades, expanded user training, broader inclusivity, and integration with traditional land tenure systems. These measures are essential to ensure equitable and efficient land governance across both urban and rural areas
The Delay and Failure of ICT Related Projects: Empirical Impediments in Ministries, Departments and Agencies in Tanzania
Get PDFThis study investigates impediments to ICT project success in MDAs in Tanzania. The study is carried using descriptive design and is carried in Dodoma and Dar es salaam with five big organizations implementing ICT projects which acted as representative of the rest. Such organizations include Tanzania Revenue Authority (TRA), TAMISEMI, Electronic Government Agency (eGA), Tanzania Ports Authority (TPA) and Tanzania Medicines and Medical Devices Authority (TMDA). Data is collected through the use of questionnaire and analysed descriptively by the use of IBM SPSS version 20. Findings disclose that presence of inadequate staff with limited skilled, lack of up to date and supporting ICT infrastructure coupled with limited financial resources lead to ICT project failure. Based on these findings, the researcher concludes that, adequate skilled staff availed with the required facilities and funded effectively lead to ICT project success or otherwise. It is therefore recommended that meritocratic staffing be implemented but still on-job trainings should be emphasized as well. In the same vein, the researcher recommends the government to set sufficient budget to obtain the required ICT equipment for better project performance. 
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
