Abstract:
We investigated the global shape of the auroral zone over the last 3000 years using paleomagnetism CALS models. A similar method of apex latitude as proposed by Oguti (1993) [J Geophys Res 98(A7): 11649–11655; J Geomag Geoelectr 45, 231–242] was adopted to draw the auroral zone. The Oguti method is examined using 50-year data from ground-based magnetometers located at high latitudes, using International Geomagnetic Reference Field (IGRF) models. The equatorward auroral limit during magnetic storms was also examined using more than 20 years of data from the Defense Meteorological Satellite Program (DMSP) satellites. The reconstructed auroral zone and the equatorward auroral limit were compared with the historical auroral witness records for 1200 AD and 1800 AD. We concluded that the 12th and 18th centuries were excellent periods for Japan and the United Kingdom, respectively, to observe auroras over the last 3000 years.

Abstract:
Quantum key distribution (QKD) offers future proof security based on fundamental laws of physics. Long-distance QKD spanning regions such as the United Kingdom (UK) may employ a constellation of satellites. Small satellites, CubeSats in particular, in low Earth orbit are a relatively low-cost alternative to traditional, large platforms. They allow the deployment of a large number of spacecrafts, ensuring greater coverage and mitigating some of the risk associated with availability due to cloud cover. We present our mission analysis showing how a constellation comprising 15 low-cost 6U CubeSats can be used to form a secure communication backbone for ground-based and metropolitan networks across the UK. We have estimated the monthly key rates at 43 sites across the UK, incorporating local meteorological data, atmospheric channel modelling and orbital parameters. We have optimized the constellation topology for rapid revisit and thus low-latency key distribution.

Abstract:
Abstract Background and Aims Dioecious species with well-established sex chromosomes are rare in the plant kingdom. Most sex chromosomes increase in size but no comprehensive analysis of the kind of sequences that drive this expansion has been presented. Here we analyse sex chromosome structure in common sorrel (Rumex acetosa), a dioecious plant with XY1Y2 sex determination, and we provide the first chromosome-specific repeatome analysis for a plant species possessing sex chromosomes. Methods We flow-sorted and separately sequenced sex chromosomes and autosomes in R. acetosa using the two-dimensional fluorescence in situ hybridization in suspension (FISHIS) method and Illumina sequencing. We identified and quantified individual repeats using RepeatExplorer, Tandem Repeat Finder and the Tandem Repeats Analysis Program. We employed fluorescence in situ hybridization (FISH) to analyse the chromosomal localization of satellites and transposons. Key Results We identified a number of novel satellites, which have, in a fashion similar to previously known satellites, significantly expanded on the Y chromosome but not as much on the X or on autosomes. Additionally, the size increase of Y chromosomes is caused by non-long terminal repeat (LTR) and LTR retrotransposons, while only the latter contribute to the enlargement of the X chromosome. However, the X chromosome is populated by different LTR retrotransposon lineages than those on Y chromosomes. Conclusions The X and Y chromosomes have significantly diverged in terms of repeat composition. The lack of recombination probably contributed to the expansion of diverse satellites and microsatellites and faster fixation of newly inserted transposable elements (TEs) on the Y chromosomes. In addition, the X and Y chromosomes, despite similar total counts of TEs, differ significantly in the representation of individual TE lineages, which indicates that transposons proliferate preferentially in either the paternal or the maternal lineage.

Abstract:
Geomatics is the discipline of electronically gathering, storing, processing, and delivering spatially related digital information; it continues to be one of the fastest expanding global markets, driven by technology. The British Geological Survey (BGS) geomatics capabilities have been utilized in a variety of scientific studies such as the monitoring of actively growing volcanic lava domes and rapidly retreating glaciers; coastal erosion and platform evolution; inland and coastal landslide modelling; mapping of geological structures and fault boundaries; rock stability and subsidence feature analysis, and geo-conservation. In 2000, the BGS became the first organization outside the mining industry to use Terrestrial LiDAR Scanning (TLS) as a tool for measuring change; paired with a Global Navigation Satellite System (GNSS), BGS were able to measure, monitor, and model geomorphological features of landslides in the United Kingdom (UK) digitally. Many technologies are used by the BGS to monitor the earth, employed on satellites, airplanes, drones, and ground-based equipment, in both research and commercial settings to carry out mapping, monitoring, and modelling of earth surfaces and processes. Outside BGS, these technologies are used for close-range, high-accuracy applications such as bridge and dam monitoring, crime and accident scene analysis, forest canopy and biomass measurements and military applications.

Abstract:
Cotton leaf curl disease (CLCuD) is the major plant viral constraint to cotton production on the Indian subcontinent (2). CLCuD is primarily caused by begomovirus, Cotton leaf curl Burewala virus (CLCuBuV), and Cotton leaf curl Multan betasatellite (CLCuMB). During 2011 in Burewala, Pakistan, plants in a production field of Luffa cylindrica (Ghia tori) were infested with the whitefly Bemisia tabaci (Genn.), and ~60% of the plants exhibited leaf curling and stunting symptoms, reminiscent of those caused by begomoviruses (Geminiviridae). Total DNA was extracted from five different symptomatic leaf samples using the CTAB method (1), and extracts were analyzed by Southern blot hybridization. As a probe, we used a 1.1-kbp fragment of CLCuBuV and a positive signal was obtained from all five samples. Total DNA was used as template for rolling circle amplification (RCA) using the TempliPhi DNA Amplification Kit (GE Healthcare, Little Chalfont, United Kingdom). The amplified RCA products were digested with EcoRI, and the resulting ~2.7-kbp fragments from each isolate were directionally cloned into the EcoRI digested, pGEM-3Zf+ (Promega, Madison, WI) plasmid vector. PCR was used to amplify the prospective, associated betasatellite and alphasatellite molecules using the primers BetaF5′-GGTACCGCCGGAGCTTAGCWCKCC-3′ and BetaR5′-GGTACCGTAGCTAAGGCTGCTGCG-3′, and AlphaF5′-AAGCTTAGAGGAAACTAGGGTTTC-3′ and AlphaR5′-AAGCTTTTCATACARTARTCNCRDG-3′, respectively. The putative satellite amplicons, at ~1.4 kbp each were cloned in the plasmid vector pGEMT-Easy (Promega, Madison, WI) and sequenced. BLASTn comparisons of the apparently full-length begomoviral genomes, at 2,753 nt, against the NCBI database revealed that all five isolates were most closely related to CLCuBuV (FR750321). In addition, one each of beta- and alpha-satellite were amplified from all five samples at 1,393 and 1,378 bases, respectively. The beta- and alpha-satellites were most closely related to CLCuMB (HE985228) and the Gossypium darwinii symptomless alphasatellite (GDaSA) (FR877533), respectively. Pairwise sequence comparisons of the top 10 BLASTn hits using MEGA5 indicated that the helper begomovirus shared 99.9% identity with CLCuBuV (FR750321), the most prevalent helper virus currently associated with the leaf curl complex in Pakistan. Based on the ICTV demarcation for begomoviral species at <89%, it is considered a variant of CLCuBuV. The resultant beta- and alpha-satellite sequences were 98.1% and 97.8% identical to CLCuMB (HE985228) and GDaSA (FR877533), respectively, and are the most prevalent satellites associated with the CLCuD complex in Pakistan and India (2). To our knowledge, this is first report of the CLCuBuV-CLCuMB-GDaSA complex infecting a cucurbitaceous species, and the first report of L. cylindrica as a host of the CLCuD complex. This discovery of CLCuBuV and associated satellites in a cucurbitaceous host that is widely grown in Pakistan and India where this complex infects cotton indicates that the host range of CLCuBuV is broader than expected. This new information will aid in better understanding of cotton leaf curl disease epidemiology in the current epidemic areas. References: (1) J. J. Doyle and J. L. Doyle. Focus 12:13, 1990. (2) S.

Abstract:
Rainfall depth is a crucial parameter in water resources and hydrological studies. Rain gauges provide the most reliable point-based rainfall estimates. However, they do not have a proper density/distribution to provide sufficient rainfall measurements in many areas, especially in arid regions. To evaluate the adequacy of satellite datasets as an alternative to the rain gauges, the Kingdom of Saudi Arabia (KSA) is selected for the current study as a representative of the arid regions. KSA occupies most of the Arabian Peninsula and is characterized by high variability in topographic and climatic conditions. Five satellite precipitation datasets (SPDSs)—CMORPH, PERSIANN-CDR, CHIRPS V2.0, TMPA 3B42 V7, and GPM IMERG V6—are evaluated versus 324 conventional rain-gauges’ daily precipitation measures. The evaluation is conducted based on nine quantitative and categorical metrics. The evaluation analysis is carried out for daily, monthly, yearly, and maximum yearly records. The daily analysis revealed a low correlation for all SPDSs (<0.31), slightly improved in the yearly and maximum yearly analysis and reached its highest value (0.58) in the monthly analysis. The GPM IMERG V6 and PERSIANN-CDR have the highest probability of detection (0.55) but with a high false alarm ratio (>0.8). Accordingly, in arid regions, the use of daily SPDSs in rainfall estimation will lead to high uncertainty in the obtained results. The best performance for all statistical metrics was found at 500–750 m altitudes in the central and northern parts of the study area for all satellites except minor anomalies. CMORPH dataset has the lowest centered root mean square error (RMSEc) for all analysis periods with the best results in the monthly analyses.

Abstract:
Precise assessment of drought and its impact on the natural ecosystem is an arduous task in regions with limited climatic observations due to sparsely distributed in situ stations, especially in the hyper-arid region of Kingdom of Saudi Arabia (KSA). Therefore, this study investigates the application of remote sensing techniques to monitor drought and compare the remote sensing-retrieved drought indices (RSDIs) with the standardized meteorological drought index (Standardized Precipitation Evapotranspiration Index, SPEI) during 2001–2020. The computed RSDIs include Vegetation Condition Index (VCI), Temperature Condition Index (TCI), and Vegetation Health Index (VHI), which are derived using multi-temporal Landsat 7 ETM+, Landsat 8 OLI/TIRS satellites, and the Google Earth Engine (GEE) platform. Pearson correlation coefficient (CC) is used to find the extent of agreement between the SPEI and RSDIs. The comparison showed CC values of 0.74, 0.67, 0.57, and 0.47 observed for VHI/SPEI-12, VHI/SPEI-6, VHI/SPEI-3, and VHI/SPEI-1, respectively. Comparatively low agreement was observed between TCI and SPEI with CC values of 0.60, 0.61, 0.42, and 0.37 observed for TCI/SPEI-12, TCI/SPEI-6, TCI/SPEI-3, and TCI/SPEI-1. A lower correlation with CC values of 0.53, 0.45, 0.33 and 0.24 was observed for VCI/SPEI-12, VCI/SPEI-6, VCI/SPEI-3, and VCI/SPEI-1, respectively. Overall, the results suggest that VHI and SPEI are better correlated drought indices and are suitable for drought monitoring in the data-scarce hyper-arid regions. This research will help to improve our understanding of the relationships between meteorological and remote sensing drought indices.

Abstract:
Soil moisture (SM) is the primary variable regulating the soil temperature (ST) differences between daytime and night-time, providing protection to crop rooting systems against sharp and sudden changes. It also has a number of practical applications in a range of disciplines. This study presents an approach to incorporating the effect of ST for the accurate estimation of SM using Earth Observation (EO) data from NASA’s SMAP sensor, one of the most sophisticated satellites currently in orbit. Linear regression analysis was carried out between the SMAP-retrieved SM and ground-measured SM. Subsequently, SMAP-derived ST was incorporated with SMAP-derived SM in multiple regression analysis to improve the SM retrieval accuracy. The ability of the proposed method to estimate SM under different seasonal conditions for the year 2016 was evaluated using ground observations from the Wales Soil Moisture Network (WSMN), located in Wales, United Kingdom, as a reference. Results showed reduced retrieval accuracy of SM between the SMAP and ground measurements. The R2 between the SMAP SM and ground-observed data from WSMN was found to be 0.247, 0.183, and 0.490 for annual, growing and non-growing seasons, respectively. The values of RMSE between SMAP SM and WSMN observed SM are reported as 0.080 m3m−3, 0.078 m3m−3 and 0.010 m3m−3, with almost zero bias values for annual, growing and non-growing seasons, respectively. Implementation of the proposed scheme resulted in a noticeable improvement in SSM prediction in both R2 (0.558, 0.440 and 0.613) and RMSE (0.045 m3m−3, 0.041 m3m−3 and 0.007 m3m−3), with almost zero bias values for annual, growing and non-growing seasons, respectively. The proposed algorithm retrieval accuracy was closely matched with the SMAP target accuracy 0.04 m3m−3. In overall, use of the new methodology was found to help reducing the SM difference between SMAP and ground-measured SM, using only satellite data. This can provide important assistance in improving cases where the SMAP product can be used in practical and research applications.

Abstract. Leaf nitrogen and leaf surface area influence the exchange of gases between terrestrial ecosystems and the atmosphere, and play a significant role in the global cycles of carbon, nitrogen and water. The purpose of this study is to use field-based and satellite remote-sensing-based methods to assess leaf nitrogen pools in five diverse European agricultural landscapes located in Denmark, Scotland (United Kingdom), Poland, the Netherlands and Italy. REGFLEC (REGularized canopy reFLECtance) is an advanced image-based inverse canopy radiative transfer modelling system which has shown proficiency for regional mapping of leaf area index (LAI) and leaf chlorophyll (CHLl) using remote sensing data. In this study, high spatial resolution (10–20 m) remote sensing images acquired from the multispectral sensors aboard the SPOT (Satellite For Observation of Earth) satellites were used to assess the capability of REGFLEC for mapping spatial variations in LAI, CHLland the relation to leaf nitrogen (Nl) data in five diverse European agricultural landscapes. REGFLEC is based on physical laws and includes an automatic model parameterization scheme which makes the tool independent of field data for model calibration. In this study, REGFLEC performance was evaluated using LAI measurements and non-destructive measurements (using a SPAD meter) of leaf-scale CHLl and Nl concentrations in 93 fields representing crop- and grasslands of the five landscapes. Furthermore, empirical relationships between field measurements (LAI, CHLl and Nl and five spectral vegetation indices (the Normalized Difference Vegetation Index, the Simple Ratio, the Enhanced Vegetation Index-2, the Green Normalized Difference Vegetation Index, and the green chlorophyll index) were used to assess field data coherence and to serve as a comparison basis for assessing REGFLEC model performance. The field measurements showed strong vertical CHLl gradient profiles in 26% of fields which affected REGFLEC performance as well as the relationships between spectral vegetation indices (SVIs) and field measurements. When the range of surface types increased, the REGFLEC results were in better agreement with field data than the empirical SVI regression models. Selecting only homogeneous canopies with uniform CHLl distributions as reference data for evaluation, REGFLEC was able to explain 69% of LAI observations (rmse = 0.76), 46% of measured canopy chlorophyll contents (rmse = 719 mg m−2) and 51% of measured canopy nitrogen contents (rmse = 2.7 g m−2). Better results were obtained for individual landscapes, except for Italy, where REGFLEC performed poorly due to a lack of dense vegetation canopies at the time of satellite recording. Presence of vegetation is needed to parameterize the REGFLEC model. Combining REGFLEC- and SVI-based model results to minimize errors for a "snap-shot" assessment of total leaf nitrogen pools in the five landscapes, results varied from 0.6 to 4.0 t km−2. Differences in leaf nitrogen pools between landscapes are attributed to seasonal variations, extents of agricultural area, species variations, and spatial variations in nutrient availability. In order to facilitate a substantial assessment of variations in Nl pools and their relation to landscape based nitrogen and carbon cycling processes, time series of satellite data are needed. The upcoming Sentinel-2 satellite mission will provide new multiple narrowband data opportunities at high spatio-temporal resolution which are expected to further improve remote sensing capabilities for mapping LAI, CHLl and Nl.

This thesis is a study of multiple access schemes for satellite land mobile systems that provide a domestic or regional service to a large number of small terminals. Three orbit options are studied, namely the geostationary, elliptical (Molniya) and inclined circular orbits. These are investigated for various mobile applications and the choice of the Molniya orbit is justified for a U. K. system.

Analyses are presented for the steady state of protocols employing pure and slotted ALOHA and for the stabilty of the slotted variant, while simulation techniques were employed to validate the steady state analysis of the slotted ALOHA protocol and to analyse the stability problem of the pure ALOHA version. An innovative technique is put forward to integrate the reservation and the acquisition processes. It employs the geographical spread of the users to form part of the random delay in P-ALOHA. Finally an economic feasibility study is performed for the spacesegment. For costs of capital (r) less than 23 % the discounted payback period is less than the project's lifetime (10 years). At r- 8% the payback period is about 5.6 years, while the internal-rate-of-return is 22.2 %. The net present value at the end of the projects lifetime is £M 70 at r-8%.

Abstract:
L’esercito italiano e la conquista della Catalogna (1808-1811) Uno studio di Military Effectiveness nell’Europa napoleonica Settori scientifico-disciplinari SPS/03 – M-STO/02 La ricerca ha lo scopo di ricostruire e valutare l’effettività militare dell’esercito italiano al servizio di Napoleone I. In primo luogo attraverso un’analisi statistica e strategica della costruzione, e del successivo impiego, dell’istituzione militare del Regno d’Italia durante gli anni della sua esistenza (1805-14); successivamente, è stato scelto un caso di studi particolarmente significativo, come la campagna di Catalogna (1808-11, nel contesto della guerra di Indipendenza spagnola), per poter valutare il contributo operazionale e tattico dei corpi inviati dal governo di Milano e la loro integrazione con l’apparato militare complessivo del Primo Impero. La tesi ha voluto rispondere alla mancanza di studi sul comportamento in guerra dell’esercito italiano e, allo stesso tempo, introdurre nella storiografia militare italiana la metodologia di studi, d’origine anglosassone e ormai di tradizione trentennale, di Military Effectiveness. La ricerca si è primariamente basata, oltre che sulla copiosa memorialistica a stampa italiana e francese, sulla documentazione d’archivio della Secrétairerie d’état impériale (Archives Nationales di Pierrefitte-sur-Seine, Parigi), del Ministère de la Guerre francese (Service historique de la Défence, di Vincennes, Parigi) e del Ministero della Guerra del Regno d’Italia (Archivio di Stato di Milano). Dal punto di vista dei risultati è stato possibile verificare come l’esercito italiano abbia rappresentato, per Bonaparte, uno strumento duttile e di facile impiego, pur in un contesto di sostanziale marginalità numerica complessiva di fronte alle altre (e cospicue) forze messe in campo da parte dell’Impero e dei suoi altri Stati satellite e alleati. Per quanto riguarda la campagna di conquista della Catalogna è stato invece possibile appurare il fondamentale contributo dato dal contingente italiano, sotto i punti di vista operazionale e tattico, per la buona riuscita dell’invasione; questo primariamente grazie alle elevate caratteristiche generali mostrate dallo stesso, ma anche per peculiarità disciplinari e organizzative che resero i corpi italiani adatti a operazioni particolarmente aggressive.

Afterwards, a particularly significant case study was chosen, as the campaign of Catalonia (1808-11, in the context of the Peninsular War), in order to assess the operational and tactical contribution of the regiments sent by the Government of Milan and their integration in the overall military apparatus of the First Empire. The thesis wanted to respond to the lack of studies on the Italian army’s behavior in war and, at the same time, to introduce the methodology of the Military Effectiveness Studies (of British and American origin and, by now, enriched by a thirty-year old tradition) in the Italian historiography. The research is primarily based, besides the numerous memoirs of the Italian and French veterans, on the archive documentation of the Secrétairerie d’état impériale (Archives Nationales of Pierrefitte-sur-Seine, Paris), of the French Ministère de la Guerre (Service historique de la Défence, of Vincennes, Paris) and of the Italian Ministero della Guerra (Archivio di Stato di Milano). About the results, it has been verified how the Italian army has become a flexible and suitable instrument for Bonaparte, albeit in a context of substantial overall numerical marginality in comparison to the heterogeneous forces available to the Empire and its others satellites and allied states. Regarding the campaign of Catalonia, instead, it was possible to ascertain the fundamental contribution of the Italian regiments, in an operational and tactical perspective, for the success of the invasion. This was primarily due to the excellent general characteristics shown by the expeditionary force, but also to disciplinary and organizational peculiarities that have made the Italian corps suitable for particularly aggressive operations.

Abstract:
This chapter examines how the part of the world ruled mainly by Christian or Muslim monotheists comprised three main overlapping zones of political, religious, and linguistic culture. First, the various western Christian kingdoms and their northern and eastern borders with the Scandinavian, Germanic, Turkic, and Slavic worlds; second, the Christian Byzantine Empire, centered on Constantinople, and its wider penumbra of satellites and commercial and diplomatic contacts, predominantly in Slavic and Turkic Eurasia; and third, the vast Islamic Empire of the Caliphate and, after its accelerating fragmentation in the ninth and tenth centuries, the ‘commonwealth’ of Islamic successor states. The literate elite in each of these regions used a lingua franca: Latin in the Christian West, Greek in Byzantium, and Arabic in the Islamic world.

Abstract:
The national history of the “House of Israel” was a contested history of a divided house. Maternal subunits within the house of Jacob came to define the Rachel-born northern kingdom of Israel, known as “Ephraim,” and the Leah-born southern kingdom of Judah, known as the “House of David.” Peripheral territories and nations traced their ancestry to foundational mothers whose houses had become satellite houses, no longer nested within the father’s house. Sons who inherited the satellite houses of their mothers became “seeds of women,” inheritors of a maternal covenant. Sent out from their chosen brothers in the Promised Land, unchosen sons dwelled “alongside” their brothers. Far from being reproductive “vessels” who produced male heirs to continue the tôlĕdôt of their husbands, foundational mothers become nations, kingdoms, military units (’ummōt), and household alliances. Mothers served as the building blocks for the biblical house of the father and its attendant kinship structures; their breasts and wombs defined social and political alliances within the house of the father.

Abstract:
In 1966 a retired British Major named Paddy Roy Bates took a liking to a small, abandoned concrete platform in the North Sea nicknamed “Rough’s Tower.” Rough’s Tower was a World War II gun tower used by the British to fire at German bombers on their way to London. By 1966, nobody wanted the rusting contraption, so Bates renamed it the “Principality of Sealand” and declared independence from the United Kingdom, six miles away. He awarded himself the title of Prince Roy, and proceeded to issue Sealand passports and Sealand stamps with pictures of his wife, Joan, an ex-beauty queen. Sealand has had a colorful history, but before 1999, nothing suggested that a chunk of concrete and steel off the English coast might have anything to do with the history of the Internet. That year, Bates agreed to let a young man named Ryan Lackey move to Sealand and begin transforming it into a “data haven.” Lackey’s company, “HavenCo,” equipped Sealand with banks of servers, and Internet links via microwave and satellite connections. Borrowing an idea from cyberpunk fiction, HavenCo aimed to rent computer space on Sealand to anyone who wanted to escape the clutches of government. It promised potential clients—porn purveyors, tax evaders, Web gambling services, independence movements, and just about any other government-shy Internet user—that data on Sealand servers would be “physically secure against any legal action.” HavenCo, the company boasted, would be “the first place on earth where people are free to conduct business without someone looking over their shoulder.” HavenCo was the apotheosis of the late 1990s belief in the futility of territorial government in the Internet era. Lackey’s company was premised on the commonplace assumption that governments cannot control what happens beyond their borders, and thus cannot control Internet communications from abroad. “If the king’s writ reaches only as far as the king’s sword, then much of the content of the Internet might be presumed to be free from the regulation of any particular sovereign,” wrote Duke law professor James Boyle, generalizing the point.

Abstract:
This chapter empirically examines factors affecting the adoption of broadband in the developing countries of Bangladesh and the Kingdom of Saudi Arabia (KSA). In the case of Bangladesh, attitudinal, normative, and control factors—discussed in the UK case study in Division I of this book—were used and adapted in order to provide insights about broadband adopters and non-adopters within the developing nations. In order to examine the adoption of broadband in the KSA, a number of variables were employed, which also included some of the variables discussed in the UK case study in Division I. As the Internet was introduced comparatively late in Bangladesh (in 1996), in early 2004 the total penetration of Internet within the country was only 0.25 percent (Totel, 2004). It was suggested that the major obstacles associated with low Internet penetration were the low economic status and still-developing infrastructure within the country (Totel, 2004). A recent media report further emphasised that “Bangladesh is not anywhere on the global broadband map, but it is doing its best to get online. Local service provider, DNS SatComm has started deploying fixed wireless gear from Cambridge Broadband and will offer access to government offices, and other commercial entities” (Malik, 2005). It has also been suggested that Internet connection is slow and costly and not affordable by the general public (Hossain, 2004). Given the situations of Bangladesh in terms of demography, telecommunication infrastructure, and affordability of Internet by people, it was felt that understanding factors including cost of Internet access and subscription affecting consumer adoption might help to encourage further diffusion of high speed Internet. In the KSA, the Internet has taken some time to diffuse and is therefore seen as a relatively new technology. The KSA first started with dial up connections and then moved on to adopt broadband and satellite connections to provide better data communication services to its citizens. However, even with the availability of broadband technology, the rate of adoption is considered to be relatively poor in comparison to other developed countries such as the UK, as well as newly industrialised leading broadband users, such as South Korea (Oh et al., 2003). This poor connectivity is often claimed to be caused by website filtration in the region. Consequently, broadband adoption has been slower than expected in the region. Furthermore, a survey of existing literature on broadband adoption suggests that although both macro and micro level studies were conducted in order to understand the deployment of broadband in the developed world and leading countries such as South Korea, none of these studies focus upon developing countries, such as Bangladesh and the KSA. Although this could be attributed to the slow infrastructure development and low rate of adoption within the two countries, this has provided the motivation for undertaking exploratory research in order to develop an understanding of the perceptions of consumers regarding broadband adoption in these developing nations. Thus, this chapter aims to explore the reasons for the slow adoption of broadband in Bangladesh and the KSA by examining the individual level factors affecting broadband uptake in both cases. The research will thereby seek to adapt the individual level factors from the UK case study (Division I) and attempt to examine if and why the adapted factors affect consumers’ attitudes towards the adoption of broadband in the countries. The chapter begins with a brief discussion of the theoretical basis and variables employed to examine broadband adoption. This is followed by a brief discussion of the utilized research methods. The findings are then presented and discussed. Finally, a conclusion to the chapter is provided.
