The Impact of SMART Media Technologies (SMT) on the Spiritual Experience of Hajj Pilgrims
Over the last three decades, information and communication technologies have advanced rapidly and continue to do so. Nowadays, the popularity and spread of socalled Smart Media Technologies (SMT) is not only transforming the lives of tourists around the world in general, but is impacting on the experience of pilgrims on the Hajj in Saudi Arabia in particular. Indeed, the Saudi government has undertaken a number of initiatives to encourage the use of SMT in the religious tourism industry. Specifically, the availability of SMT services such as Hajj Apps, E-bracelets for pilgrims, free WIFI and mobile charging services in Grand Mosques (in both Makkah and Madinah), dedicated social media websites, and the ability of pilgrims to take advantage of smartphone activities are facilitating and enhancing their technological and social experience of the Hajj. However, the introduction of ‘high-tech’ into the Hajj is arguably impacting on the nature of the pilgrims’ experience, challenging its fundamental spirituality by transforming it into something more akin to a ‘cyber experience’, an experience which competes with and jeopardises the principles of the Islamic religious journey of the Hajj with its focus on worship, simplicity and nonostentatious behaviour. Therefore, the purpose of this paper is to explore how the spiritual experience of pilgrims may be influenced by the availability and use of various SMT services. The findings suggest ways in which these technological services both enhance and impact negatively on the pilgrim’s spiritual experience
SMART Media Technologies impact on the Spiritual Experience of Hajj Pilgrims
Over the last two decades, information and communication technologies have advanced rapidly and continue to do so. Currently, the popularity and spread of SMART Media Technologies (SMT) is not only transforming the lives of tourists around the world in general, but is impacting on the experience of pilgrims on the Hajj in Saudi Arabia in particular,(Brdesee et al, 2013). Indeed, the Saudi government has undertaken a number of initiatives to encourage the use of SMT in the religious tourism industry, (Majid, 2016).
Specifically, the availability of SMT services such as Hajj Apps, E-bracelets for pilgrims, free WIFI and mobile charging services in Grand Mosques (in both Mecca and Madinah), dedicated social media websites, and the ability of pilgrims to take advantage of SMART phone activities are facilitating and enhancing their technological and social experience of the Hajj (Naar, 2015; also BBC, 2016). However, arguably the introduction of ‘high-tech’ into the Hajj is arguably impacting on the nature of the pilgrims’ experience, challenging its fundamental spirituality by transforming it into something more akin to a ‘cyber experience’, an experience which competes with and jeopardies the principles of the Islamic religious journey of the Hajj with its focus on worship, simplicity and no ostentatious behaviour. Therefore, the purpose of this paper is to explore how the spiritual experience of pilgrims may be influenced by the availability and use of various SMT services. The findings suggest ways in which these technological services both enhance and impact negatively on the pilgrim’s spiritual experience
Optimized imaging using non-rigid registration
The extraordinary improvements of modern imaging devices offer access to data
with unprecedented information content. However, widely used image processing
methodologies fall far short of exploiting the full breadth of information
offered by numerous types of scanning probe, optical, and electron
microscopies. In many applications, it is necessary to keep measurement
intensities below a desired threshold. We propose a methodology for extracting
an increased level of information by processing a series of data sets
suffering, in particular, from high degree of spatial uncertainty caused by
complex multiscale motion during the acquisition process. An important role is
played by a nonrigid pixel-wise registration method that can cope with low
signal-to-noise ratios. This is accompanied by formulating objective quality
measures which replace human intervention and visual inspection in the
processing chain. Scanning transmission electron microscopy of siliceous
zeolite material exhibits the above-mentioned obstructions and therefore serves
as orientation and a test of our procedures
Assessing the Long Term Impact of Phosphorus Fertilization on Phosphorus Loadings Using AnnAGNPS
High phosphorus (P) loss from agricultural fields has been an environmental concern because of potential water quality problems in streams and lakes. To better understand the process of P loss and evaluate the effects of different phosphorus fertilization rates on phosphorus losses, the USDA Annualized AGricultural Non-Point Source (AnnAGNPS) pollutant loading model was applied to the Ohio Upper Auglaize watershed, located in the southern portion of the Maumee River Basin. In this study, the AnnAGNPS model was calibrated using USGS monitored data; and then the effects of different phosphorus fertilization rates on phosphorus loadings were assessed. It was found that P loadings increase as fertilization rate increases, and long term higher P application would lead to much higher P loadings to the watershed outlet. The P loadings to the watershed outlet have a dramatic change after some time with higher P application rate. This dramatic change of P loading to the watershed outlet indicates that a “critical point” may exist in the soil at which soil P loss to water changes dramatically. Simulations with different initial soil P contents showed that the higher the initial soil P content is, the less time it takes to reach the “critical point” where P loadings to the watershed outlet increases dramatically. More research needs to be done to understand the processes involved in the transfer of P between the various stable, active and labile states in the soil to ensure that the model simulations are accurate. This finding may be useful in setting up future P application and management guidelines
Animal manures applied to soil: phosphorus bioavailability, losses to water and erosion
Comunicação oral da qual só está disponível o resumo.Phosphorus (P) is a non renewable resource which highlights the
significance of developing and using alternative sources of P for a sustainable
agriculture. Animal manure is an option but its application to soils to meet crop
nitrogen needs requires careful management practices to minimize freshwater
eutrophication. The aim of this work was to evaluate the partitioning of applied P
between plant uptake, losses to water, and erosion losses when using different
animal manures and a mineral P fertilizer. A field trial was conducted at an erosion
experimental station. The treatments were: Control (0 kg P/ha); cattle manure; solid
fraction of pig and duck slurry and superphosphate, each applied at a rate of 50 kg
P/ha after Lolium sp was sown. Soil samples from each trial were collected over the
9-month study and the water extractable soil P determined. It was found that
desorption of P from all additions rapidly increased soon after P application (2
weeks). After that water extractable soil P remained fairly constant. While duck
slurry desorbed the largest concentration of P, all sources have the potential to
desorb P that could accelerate eutrophication. Plant uptake of P was greater with
cattle manure added and released the least amount of P to water compared with the
other sources of P. The partitioning of applied P between plant uptake and losses to
runoff and sediments ranged between 5-12 % with the higher values in Duck
treatment. Animal manures significantly increased soil Olsen-P, plant production and P
uptake relative to mineral fertilizer. Animal manures can be considered as a source of
available P nevertheless to avoid eutrophication risks increase plant P use efficiency is also
important
Cyprus' image—a sun and sea destination—as a detrimental factor to seasonal fluctuations. Exploration into motivational factors for holidaying in Cyprus
Cyprus is established as a summer destination. To aid the destination in developing its winter season as well, this research uses a qualitative inductive approach to explore the tourists’ current image of the island and their motivations of visiting it. The research indicates that the current image, which essentially portrays Cyprus as a sun-and-sea destination is thought to dissuade tourists from perceiving the island as a year-round destination. Nonetheless, increasing the pull factors of the destination through the development of unique special interest products can help in extending the tourism season as well as broaden its narrow image
Correlating Soil Test Phosphorus Losses in Runoff
Phosphorus in agricultural runoff is often a major cause of accelerated eutrophication of lakes and streams. Previous research has indicated that the amount of dissolved P (DP) in runoff is directly related to P content of the surface soil. Decades of fertilizer application at rates exceeding those of crop uptake have elevated soil test P (STP) levels in areas of intensive crop and livestock production, making this the major source of DP loss in runoff. The objective of our experiment was to relate STP content of Captina silt loam to P concentration and loss in runoff, and determine which STP method correlates best to P levels in runoff. The 57 grass plots used in this study had a wide range of STP levels. A representative soil sample was composited from the 0-2 cm depth of each plot, and STP content was determined by Mehlich III, distilled water, and iron oxide paper strip extraction methods. Simulated rain was applied at 100 mm h-1. Runoff samples were filtered and analyzed for DP content. Regression methods showed STP (regardless of extraction method) was directly related to runoff DP, but extractions with distilled water or iron oxide paper strips gave results that correlated most closely with runoff DP concentrations. Because plot runoff totals were highly variable, total DP load did not correlate well with STP
Nonpoint pollution of surface waters with phosphorus and nitrogen
Agriculture and urban activities are major sources of phosphorus and nitrogen to aquatic ecosystems. Atmospheric deposition further contributes as a source of N. These nonpoint inputs of nutrients are difficult to measure and regulate because they derive from activities dispersed over wide areas of land and are variable in time due to effects of weather. In aquatic ecosystems, these nutrients cause diverse problems such as toxic algal blooms, loss of oxygen, fish kills, loss of biodiversity (including species important for commerce and recreation), loss of aquatic plant beds and coral reefs, and other problems. Nutrient enrichment seriously degrades aquatic ecosystems and impairs the use of water for drinking, industry, agriculture, recreation, and other purposes.
Based on our review of the scientific literature, we are certain that (1) eutrophication is a widespread problem in rivers, lakes, estuaries, and coastal oceans, caused by overenrichment with P and N; (2) nonpoint pollution, a major source of P and N to surface waters of the United States, results primarily from agriculture and urban activity, including industry; (3) inputs of P and N to agriculture in the form of fertilizers exceed outputs in produce in the United States and many other nations; (4) nutrient flows to aquatic ecosystems are directly related to animal stocking densities, and under high livestock densities, manure production exceeds the needs of crops to which the manure is applied; (5) excess fertilization and manure production cause a P surplus to accumulate in soil, some of which is transported to aquatic ecosystems; and (6) excess fertilization and manure production on agricultural lands create surplus N, which is mobile in many soils and often leaches to downstream aquatic ecosystems, and which can also volatilize to the atmosphere, redepositing elsewhere and eventually reaching aquatic ecosystems.
If current practices continue, nonpoint pollution of surface waters is virtually certain to increase in the future. Such an outcome is not inevitable, however, because a number of technologies, land use practices, and conservation measures are capable of decreasing the flow of nonpoint P and N into surface waters.
From our review of the available scientific information, we are confident that: (1) nonpoint pollution of surface waters with P and N could be reduced by reducing surplus nutrient flows in agricultural systems and processes, reducing agricultural and urban runoff by diverse methods, and reducing N emissions from fossil fuel burning; and (2) eutrophication can be reversed by decreasing input rates of P and N to aquatic ecosystems, but rates of recovery are highly variable among water bodies. Often, the eutrophic state is persistent, and recovery is slow
