Abstract Background and study aims The TissueCypher Barrett’s Esophagus Assay is a novel tissue biomarker test, and has been validated to predict progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) in patients with Barrett’s esophagus (BE). The aim of this study was to evaluate the impact of TissueCypher on clinical decision-making in the management of BE. Patients and methods TissueCypher was ordered for 60 patients with non-dysplastic (ND, n = 18) BE, indefinite for dysplasia (IND, n = 25), and low-grade dysplasia (LGD, n = 17). TissueCypher reports a risk class (low, intermediate or high) for progression to HGD or EAC within 5 years. The impact of the test results on BE management decisions was assessed. Results Fifty-two of 60 patients were male, mean age 65.2 ± 11.8, and 43 of 60 had long segment BE. TissueCypher results impacted 55.0 % of management decisions. In 21.7 % of patients, the test upstaged the management approach, resulting in endoscopic eradication therapy (EET) or shorter surveillance interval. The test downstaged the management approach in 33.4 % of patients, leading to surveillance rather than EET. In the subset of patients whose management plan was changed, upstaging was associated with a high-risk TissueCypher result, and downstaging was associated with a low-risk result (P < 0.0001). Conclusions TissueCypher was used as an adjunct to support a surveillance-only approach in 33.4 % of patients. Upstaging occurred in 21.7 % of patients, leading to therapeutic intervention or increased surveillance. These results indicate that the TissueCypher test may enable physicians to target EET for TissueCypher high-risk BE patients, while reducing unnecessary procedures in TissueCypher low-risk patients.

The Impact

Acute type A aortic dissection is a surgical emergency and management of such pathology can be complex with poor outcomes when there is organ malperfusion. Carotid artery involvement is present in 30% of patients diagnosed with acute type A aortic dissection, and given its emergency and complex nature, there is much controversy regarding the approach, extent of treatment, and timing of the intervention. It is clear that the occurrence of cerebral malperfusion adds an extra layer of complexity to the decision-making framework for treatment. Standardization and validation of the optimal management approach is required, and this should ideally be addressed with large-scale studies. Nonetheless, current literature supports the need for rapid recognition and diagnosis of acute type A aortic dissection with cerebral malperfusion, immediate and extensive surgical repair, and the appropriate use of cerebral perfusion techniques. This paper aims to discuss the current evidence regarding the impact of carotid artery involvement in both the management and outcomes of acute type A aortic dissection.

TransCanada Pipelines Ltd. (TransCanada) operates approximately 37,000 km of natural gas gathering and transmission pipelines. Within the Alberta portion of this system there are almost 1100 locations where the pipeline(s) traverse slopes, primarily as the line approaches and exits stream crossings. In the past, the approach to managing the impact of slope movements on pipeline integrity has been reactive; site investigations and/or monitoring programs would only be initiated once the slope movements were sufficiently large so as to easily observe cracking or scarp development. In some cases these movements could lead to a pipeline rupture. To move to a proactive hazard management approach and to optimize the maintenance expenditure, TransCanada has developed a new slope assessment methodology. The objective of this methodology is to establish a risk-ranked list of slopes upon which maintenance decisions can be based. Using only internal and public information on site conditions as input to predictive models for rainfall-ground movement and pipe-soil interaction, a probability of pipeline failure can be generated for each slope. Estimates of risk using a consequence-matrix approach enabled the compilation of a risk-ranked list of hazardous slopes. This paper describes this methodology, and its implementation at TransCanada, and presents some of the results.

Summary This paper presents case studies focused on the interpretation and integration of seismic reservoir monitoring from several fields in conventional offshore and deepwater Niger Delta. The fields are characterized by different geological settings and development-maturity stages. We show different applications varying from qualitative to quantitative use of time-lapse (4D) seismic information. In the first case study, which is in shallow water, the field has specific reservoir-development challenges, simple geology, and is in phased development. On this field, 4D seismic, which was acquired several years ago, is characterized by poor seismic repeatability. Nevertheless, we show that because of improvements from seismic reprocessing, 4D seismic makes qualitative contributions to the ongoing field development. In the second case study, the field is characterized by complex geological settings. The 4D seismic is affected by overburden with strong lateral variations in velocity and steeply dipping structure (up to 40°). Prestack-depth-imaging (PSDM) 4D seismic is used in a more-qualitative manner to monitor gas injection, validate the geologic/reservoir models, optimize infill injector placement, and consequently, enhance field-development economics. The third case study presents a deep offshore field characterized by a complex depositional system for some reservoirs. In this example, good 4D-seismic repeatability (sum of source- and receiver-placement differences between surveys, dS+dR) is achieved, leading to an increased quantitative use of 4D monitoring for the assessment of sand/sand communication, mapping of oil/water (OWC) front, pressure evolution, and dynamic calibration of petro-elastic model (PEM), and also as a seismic-based production-logging tool. In addition, 4D seismic is used to update seismic interpretation, provide a better understanding of internal architecture of the reservoirs units, and, thereby, yield a more-robust reservoir model. The 4D seismic in this field is a key tool for field-development optimization and reservoir management. The last case study illustrates the need for seismic-feasibility studies to detect 4D responses related to production. In addition to assessing the impact of the field environment on the 4D- seismic signal, these studies also help in choosing the optimum seismic-survey type, design, and acquisition parameters. These studies would possibly lead to the adoption of new technologies such as broad-band streamer or nodes acquisition in the near future.

This study aims to analyze and critically evaluate the implementation of the management of public ownership (Milkiyah 'ammah) and State ownership (Milkiyah Daulah) in Indonesia. This study descriptively describes the implementation of both ownerships that are currently practicing in Indonesia. Theoretical approaches used is the Islamic Economic System Madzhab Hamfara (Hadza Min fadzli Rabbi) who critically evaluate the implementation of the public wealth management and state wealth in Indonesia. This research used secondary data that was obtained from Madzhab Hamfara books, literature, journal and information relating to the Indonesian State assets management system. A comparative analysis was conducted to understand the difference between the public wealth management and state wealth management in Indonesia. Findings show that the management of both, public and state ownership are not in accordance to the ownership management approach of Madzhab Hamfara Islamic Economic System. The evidence suggests that both public and state ownership are not fully managed by the Government of Indonesia. The fact shows that public ownership in the form of water, fire and pastures are managed by individuals and institutions as well as foreign parties who have fund to privatize the public ownership. Consequently, it has the impact on unequal distribution of income that cause poverty in Indonesia. This research suggest that government should implement Islamic Economic System Madzhab Hamfara in managing public and state ownership in Indonesia. =========================================== Kajian ini bertujuan untuk menganalisis dan mengevaluasi secara kritis penerapan pengelolaan kepemilikan umum (Milkiyah 'Ammah) dan kepemilikan negara (Milkiyah Daulah) di Indonesia. Studi ini menjelaskan secara deskriptif tentang implementasi pengelolaan kedua kepemilikan tersebut yang sekarang dipraktikkan di Indonesia. Teori yang digunakan dalam penelitian ini adalah Sistem Ekonomi Islam Madzhab Hamfara (Hadza Min fadzli Rabbi) yang secara kritis mengevaluasi implementasi pengelolaan kepemilikan umum dan negara di Indonesia. Kajian ini menggunakan data sekunder yang berasal buku-buku madzhab Hamfara, literatur, artikel jurnal dan informasi lainnya yang terkait dengan pengelolaan aset di Indonesia. Analisis perbandingan juga dilakukan untuk memahami perbedaan pengelolaan kepemilikan umum dan kepemilikan negara. Hasil kajian menunjukkan bahwa pengelolaan kepemilikan, baik kepemilikan umum maupun negara di Indonesia, tidak dijalankan sesuai dengan sistem ekonomi Islam Madzhab Hamfara. Bukti-bukti menunjukkan bahwa pengelolaan kepemilikan publik dan negara tidak sepenuhnya dilakukan oleh negara. Fakta juga menunjukkan bahwa kepemilikan tersebut lebih banyak diserahkan kepada lembaga-lembaga privat bahkan lembaga-lembaga asing. Akibatnya, kesenjangan pendapatan yang menjadi pemicu kemiskinan terus terjadi. Kajian ini menyarankan agar pemerintah mengimplementasikan sistem ekonomi Islam Madzhab Hamfara dalam pengelolaan kepemilikan umum dan negara di Indonesia.

Dualistic Economy

Purpose: The purpose of this paper is to analyse the nature of the South African dual manufacturing and services economy and the impact thereof on organisations from a management perspective. Problem investigated: Services account for over 65% of South Africa's gross domestic product (GDP) and reflects an escalating trend. The manufacturing sector of the economy is just over 26% of GDP. This by implication implies that the South African economy is dualistic in nature. The economy functions as an integrated component of the global economy, one that is highly competitive and turbulent in nature. The traditional management approach tends to be one based on a mechanistic, analytical and deterministic manufacturing perspective that is no longer effective in dealing with the services economy. Methodology: A literature study is undertaken and a narrative enquiry conducted by means of discussions with 24 South African executives to determine the impact of the dual economy on South African organisations and the influence thereof from a management perspective. The approach adopted was intentionally analytical-descriptive in nature. The narrative enquiry constituted open ended but structured discussions with executives in order to learn from their personal experiences in managing an organisation in what is termed to be the dual South African services and manufacturing economy. Findings: An important conclusion drawn from the study is that traditional paradigms of management that evolved within a mechanistic manufacturing economy is no longer effective for dealing with the unpredictable and disruptive changes of a highly competitive global services economy. A complexity theory based management approach it would appear may be more relevant in dealing with the emergent realities associated with a turbulent services economy. Value of the research: Seen within the context of the changing nature of the global and South African economy, the insights gained from the study could assist executives and managers in exploring alternative paradigms of management that would be more appropriate for dealing with the paradoxical nature of a dualistic economy. Conclusion: Appropriate management paradigms differ in terms of contextual realities confronting managers, namely dealing with ordered and un-ordered contextual conditions. The Cynefin Framework (Kurtz & Snowden, 2003) serves as a means of sense making in finding the most appropriate management response for dealing with the contextual realities associated with a dualistic economy.

Purpose This study aims to identify factors that managers can influence to improve effectiveness by examining the relationship between leadership and effectiveness in small and medium-sized independent hotels. Design/methodology/approach In total, 272 valid questionnaires were collected from managers of 83 small and medium-sized independent hotels in the Netherlands by using selective and snowball sampling techniques. A two-stage structural equation modelling approach was used to test the hypotheses. Findings Surprisingly, in contradiction to previous studies, neither transactional nor transformational leadership had a direct effect on organisational effectiveness. Instead, the effect was through the intervening variables of ability to acquire resources and reward mechanisms. Research limitations/implications The contradiction between this and previous studies may be due to the fact that constructs used in this study do not have the universal applicability that is customarily assumed and further investigation is needed. Practical implications This study suggests that managers in this type of hotel, first, should be adaptable in their leadership style and not rely on transactional leadership alone; second, managers must pay attention to resource acquisition; and third, managers must retain staff by using the right reward mechanism. Originality/value This study contributes to the literature of leadership and effectiveness in small and medium-sized independent hotels by being the first to focus on the impact of ability to acquire resources and reward mechanism. It also makes an important contribution to the growing body of hospitality literature that probes the supposed universal validity of organisational studies’ constructs.
