Captain Barker's paper was presented at a one-day seminar on The Selection and Display of Navigational Information at Sea, jointly organised by the Royal Institute of Navigation and the Nautical Institute in London on 11 December 1980.It does not seem so long ago since a shipmaster could not do better than proceed at utmost speed, mindful of sea conditions for heavy weather damage and of fog, for a successful conclusion to a commercial venture. Today the cost of bunkers may exceed the income earned on the freight. Commercial organizations carrying their own cargoes have always had to operate at speeds that relate to freight levels, but owners with their ships on charter, who were never very concerned in conserving bunkers, are now more closely scrutinized on the way they operate their ships, and particular attention is paid to the speed-consumption curve.

Trust is critical in remote sensor systems to exchange the information from source to goal. The Dynamic Source Protocol computes the substitute way, if any hub neglects to exchange the information. The Dynamic Source Protocol does not have any worked in usefulness to figure a substitute way if the way has a vindictive hub. With the cost of an interloper recognition framework we can identify the vindictive hub and modify the information/parcel exchange way. Notwithstanding, gatecrasher location framework is extremely costly for remote sensor systems and there is no certification in identifying a malevolent hub. In the ebb and flow look into a trust-based approach is prescribed to limit the overheads of gatecrasher location framework and it likewise recognizes the anomalous conduct hubs. The proposed demonstrate utilizes the rehashed recreations to distinguish flawed hubs through the agreeable exertion in the sensor organize and additionally judges the trust of progressive hubs. Reenactments were exhibited for standardized result of parcel dropping, normal rebate result, and trust connection.

The Norwegian National Day (17 May, also referred to as Constitution Day) stands out as one of the most popular National Day celebrations in Europe. According to surveys, around seven out of every 10 Norwegians take part in a public celebration during this day. This means that the National Day potentially has an impact on the way people reflect upon national identity and its relationship to the Lutheran heritage. In this paper, I will focus on the role religion plays in the Norwegian National Day rituals. Researchers have described these rituals as both containing a significant religious element and being rather secularized. In this article, I discuss the extent to which the theoretical concepts civil religion and religious nationalism can help us understand the role of religion, or the absence of religion, in these rituals. Based on surveys of the general population, I analyze both indicators of civil religion and religious nationalism. The two phenomena are compared by looking at their relation to such items as patriotism, chauvinism, and xenophobia. The results show that civil religion explains participation in the National Day rituals better than religious nationalism.

In recent years, the telecom market has been very competitive. The cost of retaining existing telecom customers is lower than attracting new customers. It is necessary for a telecom company to understand customer churn through customer relationship management (CRM). Therefore, CRM analyzers are required to predict which customers will churn. This study proposes a customer-churn prediction system that uses an ensemble-learning technique consisting of stacking models and soft voting. Xgboost, Logistic regression, Decision tree, and Naïve Bayes machine-learning algorithms are selected to build a stacking model with two levels, and the three outputs of the second level are used for soft voting. Feature construction of the churn dataset includes equidistant grouping of customer behavior features to expand the space of features and discover latent information from the churn dataset. The original and new churn datasets are analyzed in the stacking ensemble model with four evaluation metrics. The experimental results show that the proposed customer churn predictions have accuracies of 96.12% and 98.09% for the original and new churn datasets, respectively. These results are better than state-of-the-art churn recognition systems.

The Kemtek 1000 Sample Processor has been evaluated for precision, accuracy, speed and reliability. Precision was better than 1.0% at all volumes tested and accuracy within ±5%. A l00-tube assay could be set up within 15 min when patient specimens plus two reagents were sampled using a two probe system. Carry-over could be reduced to <0.01% by using a sufficient number of wash steps, the latter being related to the assay requirements. Evidence was found for adsorption of protein to the probe tubing but inaccuracies due to this could be reduced by introducing wash steps between samples. Problems over 12 months have been minor and quickly resolved. The authors were pleased with the way the processor performed and their staffhave confidence in leaving it to set up their assays.

In public policy scholarship on policy design, emotions are still treated as opposed to goals, and their presence is assumed to signal that things have gone wrong. We argue, however, that understanding how and for whom emotions matter is vital to the dynamics of policy designs because emotions are central to the capacity building of policy intermediaries and, with that, to the success of public policies. We examine the case of Czech single mothers in their role as intermediaries in ‘alimony policy’. Our interpretive survey provided single mothers an opportunity to express the way they experience the policy emotionally. The analysis reveals that the policy goal of the child’s well-being is produced at the cost of the mother’s emotional tensions and that policy designs defuse these emotional tensions, implicitly. These contradictory emotions expressed by mothers show us a gateway to problematising policy designs in a novel way, which reconsiders construing policy design as a technical, solution-oriented enterprise to one in which emotional tensions intervene in policy design and are essential for succeeding.

Online reputation has become a key marketing-mix variable in the digital economy. Our study helps managers decide on the effort they should use to manage online reputation. We consider an online reputation race in which it is important not just to manage the absolute reputation, but also the relative rating. That is, to stay ahead, a firm should try to have ratings that are better than those of its competitors. Our findings are particularly significant for platform owners (such as Expedia or Yelp) to strategically grow their base of participating firms: growing the middle of the market (firms with average ratings) is the best option considering the goals of the platform and the other stakeholders, namely incumbents and consumers. For firms, we find that they should increase their effort when the mean market rating increases. Another key insight for firms is that, sometimes, adversity can come disguised as an opportunity. When an adverse event strikes the industry (such as a reduction in sales margin or an increase in the cost of effort), a firm’s profit can increase if it can manage this event better than its competitors.

While Archaeology started to take form as a professional discipline, Alternative Archaeologies grew in several ways. As the years went by, the image of Archaeology started being corrupted by misconceptions and a lot of imagination, and those professionals that were claiming to be scientists forgot one of their first responsibilities; the public. This lack of interest is one of the reasons why today, a vast majority of society believes in many clichés of the past that alternative archaeologists have used to build a fictitious History that is not innocent at all. From UFOs and the mysteries of great civilizations to the political interpretation of the past, the dangers of Alternative Archaeologies are clear and under our responsibility. This paper analyzes this situation in order to propose a strategy that may make us the main characters of the popular imagery in the mid-term. Since confrontation and communication do not seem to be effective approaches, we need a change in the paradigm based on Public Archaeology and the increase of our presence in everyday life.

While it would appear that the motivations to incorporate the Directorate of Special Operations (DSO) or Scorpions into a new South African Police Service directorate are largely politically driven, there are a number of practical obstacles standing in the way of a ‘smooth’ incorporation. Foremost among these is the manner of operations of the Scorpions, the way that they investigate certain crimes by means of prosecution-led teams, and their more effective use of intelligence-driven crime information. This is diametrically opposed to the SAPS investigation modus operandi, which is largely reactive. Furthermore, many of the Scorpions investigators, representing as they do a vast pool of built up experience and expertise, do not want to serve in the SAPS under the latter’s investigating regime. Other sticking points would be the fact that they are paid infinitely better than SAPS detectives, are better funded and resourced, have a far lighter case load (and one shared in a team) – all in direct contrast to members of the SAPS.

Sebagian rangkaian aktivitas ziarah di beberapa situs arkeologi di KabupatenTapin dan Hulu Sungai Utara, Kalimantan Selatan menunjukkan adanya perilaku dan situasi di tempat ziarah yang mendukung kegiatan pelestarian tinggalan arkeologi. Oleh karena itu, peluang ini perlu dimanfaatkan agar pihak arkeologi mendapatkan cara pelestarian yang melibatkan masyarakat dan murah biayanya. Berkaitan dengan itu, maka penelitian ini ditujukan untuk menemukan cara dalam memanfaatkan perilaku dan situasi untuk pelestarian tinggalan arkeologi dengan tidak mengganggu kegiatan ziarah, namun kegiatan pelestarian yang diinginkan dapat dipertanggungjawabkan secara keilmuan (arkeologi). Penelitian ini dilakukan dengan menggunakan metode deskriptif. Implementasinya di lapangan dilakukan dengan mendeskripsikan tinggalan arkeologi untuk mengetahui kondisi eksistingnya dan riwayat pemugaran yang pernah dilakukan. Pendeskripsian ini untuk mengetahui hal-hal apa saja yang dapat dimanfaatkan dalam mendukung kegiatan pelestarian. Hasil yang diperoleh menunjukkan bahwa di situs-situs arkeologi yang diziarahi terdapat situasi dan perilaku para peziarah yang mendukung kegiatan pelestarian, seperti harus bersikap sopan, tidak merusak barang-barang yang ada di tempat ziarah (dalam konteks ini termasuk tinggalan arkeologi) dan situasi di tempat ziarah yang sakral, serta adanya teguran dari orang yang hidup di alam sebelah jika tidak sopan atau melanggar tata cara ziarah. Jadi kesimpulannya, situasi dan perilaku tersebut perlu dimanfaatkan untuk mendukung pelestarian tinggalan arkeologi. Caranya dengan memberi dukungan, karena perilaku yang baik (tidak merusak warisan budaya) merupakan bagian dari isi undang-undang cagar budaya. Selain itu, juga menghormati situasi yang tercipta di tempat ziarah karena itu merupakan pemaknaan oleh sebagian masyarakat. Agar cara mendukung dan menghormati dapat dipertanggungjawabkan, arkeolog harus jujur dan netral dalam kegiatan pelestarian.Kata kuci: tinggalan arkeologi, ziarah, situasi, perilaku, pelestarianSome parts of pilgrimage activities at several archeological sites in Tapin and Hulu Sungai Utara Districts indicate the existence of behaviors and conditions that support the conservation of archeological remains. This opportunity needs to be utilized, therefore the archeological party can obtain conservation methods that involve the community and the cost is cheap. The research goal is to gain proper method on utilizing pilgrim behaviors and situation for preserving archeological remains without interfering the pilgrimage activities, but the desired of conservation activities can be scientifically accounted (archeology). This research was conducted by using descriptive methods. Its implementation in the field was carried out by describing the archaeological remains of the existing conditions and the history of restoration that had been carried out. The describing of the pilgrim behaviors and the place conditions of pilgrimage is to find out what things can be utilized in supporting conservation activities. The results indicate that at the visited archeological sites there are conditions and behavior of pilgrims who supported conservation activities, such as having to be polite, not damage the items that are in the place of pilgrimage (in this context including archeological remains) and the situation in the sacred place of pilgrimage, as well as the rebuke of people living in the adjoining realm if they are not polite or violate to the procedure of pilgrimage. It is concluded that the situation and behavior need to be used to support the preservation of archeological remains. The way is by giving support, because good behavior (not damaging cultural heritage) is part of the contents of the cultural heritage law. In addition, it also respects the situation created in the place of pilgrimage because it is a meaning by some people. In order to be able to support and respect ways, archaeologists must be honest and neutral in conservation activities.Keywords: archaeological remains, pilgrimage, situations, behavior, preservation.
