The role of resource structuring, marketing, and networking capabilities in forming DMO orchestration capability toward sustainable value creation

Abstract The study investigates the formation of Destination Management Organization (DMO) orchestration capability under the influence of environmental forces to achieve sustainable value creation. The study suggests that the DMO’s orchestration capabilities, encompassing resource structuring, marketing, and networking capability, significantly influence the achievement of sustainable value creation as a strategic destination performance. Networking capability, in particular, plays a vital role as a mediator in this process. Social-cultural preservation becomes the primary concern of DMOs in their efforts to attain sustainable value creation. Notably, environmental forces significantly affect destination orchestration capabilities, except for marketing capability, which the unprecedented research context may influence. The study surveyed respondents who are top management executives of DMOs, encompassing 153 DMOs from various destinations in Indonesia. The novel findings of this study empirically establish that integrating three core capabilities—resource structuring, marketing, and networking—shapes the orchestration capabilities of Destination Management Organizations (DMOs) in response to environmental pressures. It extends and enhances our understanding of the determinants of destination management that lead to the strategic performance goal of sustainable value creation. From a managerial standpoint, the role of a destination organization’s manager is pivotal in the comprehensive development and shaping of the three pillars of orchestration capability. Mere mastery and practice of one of these pillars, or the neglect of any, amplify the risk of failing to attain the desired sustainable value creation. The research context in Indonesia, as a developing country with a noteworthy surge in the tourism sector, lends significant relevance to this study.
Modelling the thermal evolution of slow-spreading ridge segments and their off-axis geophysical signature

Systematic studies conducted between 15°N and 40°N over ridge segments along the slow-spreading Mid-Atlantic Ridge (MAR) have shown that segment characteristics are related to the thermal state of the segments and gradually vary with their length. This paper presents further developments of a 3-D model, based on the presence of a hot zone located under the segment centres (Gac et al. 2003), to (1) quantify the thermal structures and the geophysical signatures of segments of various lengths, considered as representative of the various MAR segments; (2) test if a simple and single model of thermal evolution can account for the characteristics of all segments and (3) explain the past evolution of the segmentation, as is observed off-axis along the MAR. The modelled thermal structure and three simulated geophysical outputs [crustal structure , along-axis variations of the earthquake maximum depth and the mantle Bouguer gravity anomalies (MBA)] are found to be directly controlled by the shape (geometry and dimensions) of the hot zone. A consistent fit between model outputs and along-axis variations of the geophysical observables over the various segments is obtained by varying solely the length of the hot zone. This result shows that segments of different length may in fact constitute the different stages of a single evolution process: the axial geophysical characteristics of the segment would progressively evolve from those of shorter segments to those of longer ones, as the hot zone lengthens along-axis. A subsequent shortening of the segment would result from a simultaneous shortening of the hot zone, segment characteristics reverting back from those of longer segments to those of shorter ones. Three geophysical fields (topography, gravity and magnetic anomalies) are simulated as the results of the thermal evolution of aligned and offset segments the length of which evolves through time. These simulations succeed in fitting observations for the entire range of observed axis offsets between adjacent MAR segments. The segment evolution produces peculiar off-axis isostatic topography and gravity anomaly (MBA), the rhomb-shaped patterns. Our simulations, which model adjacent offset segments having evolved through several cycles of lengthening and shortening, yield a good fit to the isostatic topography and MBA patterns observed in the off-axis region. Finally, the distribution of magnetization depends on the magnetic properties of each type of rocks and on the petrological structure of the lithosphere, which, in turn, results from its thermal structure and evolution. Modelled magnetic anomalies are shown to be in good agreement with off-axis observations along the N21°40' segment (TAMMAR) of the MAR.
System Productivity of Rabi Vegetables and Aman Rice varieties in Rabi Vegetables-Mungbean-Aman Rice Cropping Pattern

Field experiments were conducted during 2007-2010 to evaluate the agro-economic productivity of BRRI Aman rice varieties and Rabi vegetables at the Bangladesh Rice Research Institute (BRRI) in silty clay loam soil. Five Aman rice varieties having different growth durations and three winter vegetables viz., tomato, red amaranth and bush bean were evaluated in split plot design with three replications. Mungbean was grown in Kharif-I season. Rice varieties did not differ significantly in terms of grain yield (t ha -1 ). Among the three vegetables, the yields of tomato, red amaranth and bush bean were 35.02, 7.53 and 4.33 t ha -1 , respectively. Average yield of Mungbean was 0.89 t ha -1 . In case of rice equivalent yield (REY), Tomato-Mungbean-BRRI dhan33 cropping pattern produced comparatively high average REY (29.95 t ha -1 ) followed by Tomato-Mungbean-BRRI dhan39 (27.33 t ha -1 ) cropping pattern. Among the tested cropping patterns, Tomato-Mungbean-BRRI dhan33 and Tomato-Mungbean-BRRI dhan39 were more profitable than other patterns.

Increased influence of nitrogen limitation on CO2 emissions from future land use and land use change

In the latest projections of future greenhouse gas emissions for the Intergovernmental Panel on Climate Change (IPCC), few Earth System Models included the effect of nitrogen limitation, a key process limiting forest regrowth. Few included forest management (wood harvest). We estimate the impacts of nitrogen limitation on the CO2 emissions from land use and land use change (LULUC), including wood harvest, for the period 1900–2100. We use a land surface model that includes a fully coupled carbon and nitrogen cycle and accounts for forest regrowth processes following agricultural abandonment and wood harvest. Future projections are based on the four Representation Concentration Pathways used in the IPCC Fifth Assessment Report, and we account for uncertainty in future climate for each scenario based on ensembles of climate model outputs. Results show that excluding nitrogen limitation will underestimate global LULUC emissions by 34–52 PgC (20–30%) during the 20th century (range across three different historical LULUC reconstructions) and by 128–187 PgC (90–150%) during the 21st century (range across the four IPCC scenarios). The full range for estimated LULUC emissions during the 21st century including climate model uncertainty is 91 to 227 PgC (with nitrogen limitation included). The underestimation increases with time because (1) projected annual wood harvest rates from forests summed over the 21st century are 380–1080% higher compared to those of the 20th century, resulting in more regrowing secondary forests; (2) nitrogen limitation reduces the CO2 fertilization effect on net primary production of regrowing secondary forests following wood harvest and agricultural abandonment; and (3) nitrogen limitation effect is aggravated by the gradual loss of soil nitrogen from LULUC disturbance. Our study implies that (1) nitrogen limitation of CO2 uptake is substantial and sensitive to nitrogen inputs; (2) if LULUC emissions are larger than previously estimated in studies without nitrogen limitation, then meeting the same climate mitigation target would require an equivalent additional reduction of fossil fuel emissions; (3) the effectiveness of land‐based mitigation strategies will critically depend on the interactions between nutrient limitations and secondary forests resulting from LULUC; and (4) it is important for terrestrial biosphere models to consider nitrogen constraint in estimates of the strength of future land carbon uptake.
Improving sea ice type discrimination by the simultaneous use of SSM/I and scatterometer data

The multi-year sea ice (MY) concentration as determined with the NASA Team algorithm (NTA) shows an increase during winter. This unrealistic feature can be reduced using combined active and passive remote sensing data, leading to a more realistic estimation of MY area. Our joint analysis of SSM/I, QuikSCATterometer (QSCAT) and meteorological data reveals events (i.e. intervals in space and time) where increased surface roughness and volume scattering, after a melt–refreezing episode, alters the passive microwave signature of the undisturbed sea ice surface. In these events, the calculation of MY and FY areas employing the NTA leads to false estimations of their amounts. It is shown that when such events occur, QSCAT backscatter values increase by more than 3 dB. This backscatter variation can be easily detected and the FY and MY area determination of the NTA can be corrected accordingly within defined event–regions. Using this method, called Simultaneous NTA, we found that in May 2000 12 % of the area detected by the NTA as MY has to be corrected to FY. As a consequence, a detailed reanalysis of the 20-year passive microwave data set is suggested to more precisely compute the MY area.
Quantitative ecology of phytoplankton in theCochin backwater

A one-year study on the standing crop in terms of chlorophylls, primary production and total-cell counts of four station grids has shown that there were regional and seasonal variations in the magnitude of phytoplankton production in the Cochin backwater. Statistically treated using a microcomputor, a multiple regression relationship has been established between parameters within stations. But th<^ Correlation coefBclent and Standard Regression coefficient have revealed that the plankton production and the related parameters at all the stations were independent of each other and the parameters varied from station to station. Probable reasons are briefly discussed.
Gold Nanoparticles Enhance the Tumor Growth-Suppressing Effects of Cetuximab and Radiotherapy in Head and Neck Cancer In Vitro and In Vivo

Simple Summary Head and neck squamous cell carcinoma (HNSCC) treatment includes surgery, radiotherapy, and immunotherapy with the aim of eradicating cancer cells without affecting normal tissues. HNSCC expresses epidermal growth factor receptor and cetuximab, an IgG1 monoclonal antibody targeting epidermal growth factor receptor, has been approved for the treatment of HNSCC. However, cetuximab has low reactivity. Gold nanoparticles (AuNPs) were reported to enhance the local antitumor effects of radiotherapy without damaging normal cells. This study investigated the in vitro and in vivo effects of single and combination therapy with AuNPs, cetuximab, and radiotherapy on a human HNSCC cell line. Combination treatment of AuNPs + cetuximab + radiotherapy markedly reduced HNSCC cell numbers and proliferation and enhanced apoptosis compared with single and double combination treatments. Furthermore, the in vivo combination treatment (AuNPs + cetuximab + radiotherapy) reduced the tumor volume compared with the controls. This study showed that AuNPs sensitize tumors to radiotherapy and bind to cetuximab, leading to enhanced antitumor effects. Abstract Introduction: Head and neck squamous cell carcinoma (HNSCC) treatment includes surgery, radiotherapy, and immunotherapy with the aim of eradicating cancer cells without affecting normal tissues. HNSCC expresses epidermal growth factor receptor (EGFR) and cetuximab, an IgG1 monoclonal antibody targeting epidermal growth factor receptor, has been approved for the treatment of HNSCC. However, cetuximab has low reactivity and induces serious side effects. Gold nanoparticles (AuNPs) were reported to enhance the local antitumor effects of radiotherapy without damaging normal cells. Methods and Results: This study investigated the in vitro effects of single and combination therapy with AuNPs (1.0 nM), cetuximab (30 nM), and radiotherapy (4 Gy) on a human HNSCC cell line, HSC-3. Combination treatment of AuNPs + cetuximab + radiotherapy markedly reduced HSC-3 numbers and proliferation and enhanced apoptosis compared with single and double combination treatments. Furthermore, the in vivo combination treatment (AuNPs + cetuximab + radiotherapy) of a xenograft model of HSC-3 cells transplanted into nude mice (BALB/cAJcl-nu/nu) reduced the tumor volume compared with the controls. Scanning electron microscopy demonstrated the presence of AuNPs in tumor tissues and toxicity analysis indicated that AuNPs had no toxic effect on normal tissues. Conclusions: This study showed that AuNPs alone do not have a tumor-suppressing effect, but they sensitize tumors to radiotherapy and bind to cetuximab, leading to enhanced antitumor effects.
The role of trust in purchase intentions in collaborative consumption in emerging economies: A Colombian perspective

Abstract This study explores the role of trust in purchase intentions for collaborative consumption services in Colombia. Data were collected through an online survey (n = 233) to test the proposed conceptual model. Results confirmed the direct relationship among disposition of trust, trust in the intermediary, and trust in the service provider and, consequently, the positive relationship among these variables in relation to purchase intentions. Additionally, the disposition of trust does not directly influence purchase intentions. Practical implications for the enhancement of trust are provided. This work advances the literature on the influence of trust on collaborative consumption in emerging economies.
Chaos theory in hydrology: important issues and interpretations

The application of the concept of chaos theory in hydrology has been gaining considerable interest in recent times. However, studies reporting the existence of chaos in hydrological processes are often criticized due to the fundamental assumptions with which the chaos identification methods have been developed, i.e. infinite and noise-free time series, and the inherent limitations of the hydrological time series, i.e. finite and noisy. This paper is designed: (1) to address some of the important issues in the application of chaos theory in hydrology; and (2) to provide possible interpretations to the results reported by past studies reporting chaos in hydrological processes. A brief review of some of the past studies investigating chaos in hydrological processes is presented. An insight into the studies reveals that most of the problems, such as data size, noise, delay time, in the application of chaos theory have been addressed by past studies, and caution taken in the application of the methods and interpretation of the results.
Determinants of Intention towards Digital Transformation Adoption: Evidence from Vietnam’s Public Sector

Purpose: Drawing on familiar concepts such as inclusive leadership and organizational support theories, and the input-mediator-output-input model, this study aims to explore civil servants’ intention towards digital transformation adoption in the public sector of Vietnam. Method: This study takes the form of a case study of the Vietnam context and employs a quantitative method. A printed questionnaire was distributed to collect data from 892 civil servants. After excluding cases with missing data, 863 valid cases were used for data analysis. Primary data analysis was conducted using SPSS 20, Amos 20, and SMARTPLS version 4, which included descriptive statistics, testing the proposed model and hypotheses using the SEM approach, and conducting the importance-performance map analysis. Findings: The current study revealed that inclusive leadership, government support, and organisational support have both direct and indirect effects on the intention towards digital transformation adoption through the partial mediating role of organisational innovative climate. Moreover, the importance-performance map analysis revealed that while organisational support is the most important factor, it has the lowest performance. Originality: This study is pioneering in its use of the IMOI model to predict intentions towards technology adoption, particularly in the context of digital transformation, a new aspect in developing nations, including Vietnam. The study contributes to our understanding of digital transformation adoption in the public sector and will be of particular interest to government, policymakers, and service providers of new technology systems.
Latest Paleocene benthic foraminiferal extinction and environmental changes at Tawanui, New Zealand

A major extinction of intermediate-water (500–1000 m) benthic foraminiferal species coincided with a major decrease in δ13C (2.8‰) of terrestrial organic matter (n-C29 alkane) and δ34S (20‰) of whole rock sulfide in a continuous siltstone sequence in the Tawanui Section (46°S paleolatitude) along the Akitio River, southeastern North Island, New Zealand, in the middle part of the uppermost Paleocene nannofossil zone (CP8). The benthic extinction (25% of species) occurred over ∼3 kyr at ∼55.5 Ma. Increases in kaolinite/illite and kaolinite/smectite ratios and in terrestrial organic carbon percentages started ∼3 kyr before the major benthic extinctions, lasted over ∼40 kyr, and probably reflect warmer climate and increased rainfall. The productivity of planktonic foraminifera and calcareous nannoplankton decreased ∼3 kyr prior to the major extinctions and recovered at the time of benthic extinctions. These events that started ∼3 kyr before the extinction can be best explained by warming, increased rainfall, reduced salinity of surface waters, and increased influence of warm saline deep water (WSDW). Benthic foraminiferal oxygen indices indicate a strong decrease in dissolved oxygen levels within the intermediate water from low oxic (1.5–3.0 mL/L O2) to suboxic (0.3–1.5 mL/L O2) conditions coinciding with the benthic extinctions. Increases in total organic carbon (TOC) and in the hydrocarbon-generating potential of kerogen (measured as the hydrogen index (HI)) agree with the interpretation of decreased dissolved oxygen levels of the intermediate water. The lowest oxygen conditions lasted ∼40 kyr and coincided with a decrease in calcareous benthic foraminiferal productivity, highest TOC levels, and lowest δ13C of terrestrial organic carbon. Dominant formation of WSDW or sluggish intermediate-water circulation caused by warming and high rainfall in high-latitude areas most likely led to the ∼3-kyr time lag between events on land and in surface waters preceeding the extinction and the development of dysaerobia in the sea, coinciding with the major benthic extinction and decrease in δ13C and δ34S in New Zealand. Global warming of deep and intermediate waters may have caused decomposition of methane hydrate in sediments, resulting in a strongly decreased δ13C of marine carbonates, promoting dysaerobia in the ocean, and warming global climate by increased methane concentrations in the atmosphere. Upwelling of WSDW, occurring soon after it became dominant in high-latitude areas, is likely responsible for the recovery of normal salinity and the concomitant recovery of planktonic foraminifera and calcareous nannoplankton productivity in high-latitude surface waters. Minor benthic foraminiferal extinctions (9% of species) occurred ∼40 kyr after the major extinctions, lasted ≤ ∼6 kyr, and coincided with the initiation of environmental recovery.
Patient Outcomes and Rate of Intensive Care Unit Admissions Following Bariatric Surgery: A Retrospective Cohort Study of 775 Patients

Background The last two decades have seen a significant rise in obesity and its adverse consequences across the globe. Bariatric surgery has emerged as a widely employed therapeutic approach for weight reduction and alleviating the risk of obesity-related chronic diseases such as diabetes, cardiovascular diseases, and cancer. As bariatric procedures are gaining popularity, the complications associated with these procedures can not be ignored. This retrospective study aimed to investigate the incidence of intensive care unit (ICU) admissions following bariatric surgery and ICU-related mortality. Methodology This retrospective study conducted at King Hamad University Hospital, Bahrain evaluated the patient outcomes and the rate of ICU admissions following bariatric surgery between 2018 and 2022. Demographic data of the patients were extracted from electronic health records. The primary endpoint was ICU admission incidence and mortality, while secondary outcomes included risk factors, duration of ICU stay, and complications leading to ICU admission. Results Of the 775 patients included, 66.3% were female. The mean age of the patients was 35.92 ± 21.12 years. Over 91% of the patients had a body mass index above 30 kg/m2. The most common primary procedure was laparoscopic sleeve gastrectomy (75%), followed by gastric bypass (22.6%). In revision bariatric surgery, the majority (91.3%) had a conversion from sleeve gastrectomy to gastric bypass. Overall, 0.77% of patients were admitted to the ICU, with the majority being unplanned ICU admissions (0.52%). The average ICU stay was 21 days (1 to 54 days). The most common reason for ICU admission was sepsis, septic shock, and gastric leakage. Conclusions The results of this study show a relatively lower number of ICU admissions after bariatric surgery compared to previous studies.
