Abstract

Purpose

The purpose of this paper is to present the first economic valuation of four environmental attributes of the Yanachaga–Chemillén National Park (PNYCH – Parque Nacional Yanachaga-Chemillén) in Peru.

Design/methodology/approach

This study included households in three cities adjacent to the PNYCH and assessed the willingness to pay (WTP) for preservation efforts of these natural services to avoid the predicted loss in forest area by 2030 (currently 143,425 hectares per year).

Findings

The results showed that the average WTP was US$0.695 (2.3197 soles) per household annually. Added to all households in Peru (9 million), this is equivalent to approximately 6.255 million dollars annually.

Practical implications

The economic valuation of these attributes is complementary to the contingent valuation and can have a significant impact, as this data influences decision-making and public policies focused on conserving forests and biodiversity.

Social implications

Upon using the choice experiment (CE) model, the attributes that have the most significant impact on inhabitants’ well-being were economic benefits. The flora and fauna coverage attributes were beneficial for the inhabitants of the place because they valued the proposed recovery and conservation program in a positive and differential way.

Originality/value

From the collection of valuable economic data, the novelty lies in using the CE method, which has not yet been applied in valuations of natural ecosystem services in Peru.

Abstract

Purpose

The Purpose of this research is to make an energy efficient finite state machine (FSM) in order to achieve the core objective of green computing because FSM is an indispensable part of multiple computer hardware.

Design/methodology/approach

This study uses ultra-scale plus FPGA architecture in place of seven-series field-programmable gate array (FPGA) for the implementation of the FSM design and also uses output load scaling for the design of environment-friendly FSM. This design study is done using Verilog Hardware description language and Vivado integrated system environment design tools and implemented on 16 nm ultra-scale FPGA architecture.

Findings

There is up to 98.57% reduction in dynamic power when operating frequency is managed as per smart job scheduling. There is up to a 21.97% reduction in static power with proper management of output load capacitance. There is up to 98.43% saving in dynamic power with the proposed management of output load capacitance.

Originality/value

The proposed design will be environment friendly that eventually leads to the green earth. This is the main motive of the research area i.e. green computing.

Abstract

Purpose

This paper aims to characterize the sexual maturation of M. flexuosa plantations in Tulumayo.

Design/methodology/approach

The methodology in this paper was selection of three plots in open field and usage of different densities of planting, after the maturation of the first plants, we began the quarterly evaluation. There was total 28 evaluations in seven years of age.

Findings

As a result, it was determined that at 12 years, the plots with lower density presented a greater number of mature individuals, with a predominance of female palms that produced an average of four bunches of fruit per year, and males five inflorescences. In addition, 15% of adult female plants went dormant, whereas males accounted for 3.4%. Reproductive cycles began in September and culminated in October of the following year, which were synchronized with rainfall.

Originality/value

Planting density was a determining factor in the early maturity of M. flexuosa and sustainable plantation management.

Abstract

Purpose

This work aims to present the design of a new continuous tool-path strategy for open-source low-cost fused deposition modeling (FDM) machines, such as Fab@Home or RepRap; and the development of an innovative integrated tool to design and fabricate customized tracheal stents with any FDM machine and six patient parameters. Both contributions were validated and implemented by obtaining a customized medical-grade silicone tracheal stent.

Design/methodology/approach

For the design of the new deposition strategy, a Python programming language was used. The new tool-path strategy was proposed as a continuous path to avoid drops and gaps and to improve the accuracy of the final model. Meanwhile, patient parameters were obtained by medical doctors and introduced into the innovative integrated system. On the one hand, one mold generated automatically, and viewed with Matlab® software, was fabricated with a Fab@Home machine, optimized with the continuous tool-path strategy. On the other hand, the same generated mold was viewed in SolidWorks/Excel software and was fabricated using a commercial FDM machine. Finally, the mold was filled with medical grade silicone, and a silicone tracheal stent was obtained.

Findings

Path planning for extrusion technologies is still a major concern, especially for open-source FDM machines. The results obtained in this work show the benefits of applying the newly developed continuous tool-path strategy to optimize the performance and efficiency of these machines. In addition, the proposed innovative integrated system allows the fabrication of customized tracheal stents rapidly and affordably.

Practical implications

The possibility of obtaining customized tracheal stents is a worthy challenge. Medical doctors could play a more active role and interact during the design process, helping to obtain more suitable stents. The method proposed herein would provide the opportunity to obtain real values from the trachea of a patient in the operating room and quickly fabricate a customized stent that would fit the patient's trachea perfectly.

Originality/value

The results obtained in this work are relevant and have future applications in both the medical and the additive manufacturing fields. The optimized tool-path strategy can help to improve and enhance the use of low-cost FDM machines. Moreover, the innovative automatic design approach to fabricate tracheal stents may open new market opportunities in the medical device field.

Abstract

Purpose

In order to understand interactions aw vs equilibrium moisture content (EMC) in fortified coconut powder, moisture sorption isotherms were constructed under different storage conditions in order to predict the changes in their physical, chemical and microbiological properties that occur during storage and processing, which are unique to each food.

Design/methodology/approach

For which the moisture sorption isotherms were determined at three different temperatures (15, 25 and 35 °C), in a range of water activity from 0.1 to 0.90. Nine models, namely, the GAB, BET, Oswin, Smith, Halsey, Henderson, Chung and Pfost, Peleg and Caurie equations, were fitted to the sorption data. Various statistical tests were adopted as criteria to evaluate the fit performance of the models.

Findings

Of the models tested, the Peleg model gave the best fit to experimental data (R2 = 0.997; RMSE = 0.276), across the full range of water activities and at different temperatures. Humidity of the monolayer (mo) was found between 2.54 and 2.34%, a fundamental parameter to define the storage and control conditions, given that it is considered the value at which the product is more stable. The net sorption isosteric heat (Qst) increased to maximum and then diminished with increased moisture content (Xw); maximum values were obtained in the Xw interval between 0.48 and 2.87% (db), being between 35.72 and 99.26 kJ/mol, where the maximum value indicates coverage of the strongest bond sites and higher adsorbate-adsorbent interaction.

Originality/value

These results provide reliable experimental data on water absorption isotherms of the CP + FAC important to determine optimal processing, storing and packaging conditions.

Abstract

We present a legislative background and assessment of approaches to financing the US Department of Veterans Affairs (VA) healthcare services, and focus on issues related to beneficiaries eligible for both VA and Medicare benefits. We refer to a large, VA Medical Center (VAMC) hospital and healthcare complex as a case for comparison of financing approaches. Several legislative proposals had been made to grant the VA funding transfers from Medicare. To date, none has passed in the Congress. Our analysis shows that payments from Medicare would need to be adjusted for the specialized characteristics of VAMC patients, as well as for higher capital costs related to the federal VAMC mandate to maintain reserve capacity for national health emergencies, in order to appropriately apply Medicare payments.

This is a comparative investigation of how university libraries in the United States, Canada and Spanish-speaking Latin America are responding to predatory publishing.

Abstract

Purpose

This is a comparative investigation of how university libraries in the United States, Canada and Spanish-speaking Latin America are responding to predatory publishing.

Design/methodology/approach

The Times Higher Education World University Rankings was used to identify the top ten universities from each of the US and Canada, as well as the top 20 Spanish-language universities in Latin America. Each university library's website was scrutinized to discover whether the libraries employed scholarly communication librarians, whether they offered scholarly communication workshops, or whether they shared information about scholarly communication on their websites. This information was further examined to determine if it discussed predatory publishing specifically.

Findings

Most libraries in the US/Canada sample employ scholarly communication librarians and nearly half offer workshops on predatory publishing. No library in the Latin America sample employed a scholarly communication specialist and just one offered a workshop addressing predatory publishing. The websites of the libraries in the US and Canada addressed predatory publishing both indirectly and directly, with US libraries favoring the former approach and Canadian libraries tending towards the latter. Predatory publishing was rarely addressed directly by the libraries in the Latin America sample; however, all discussed self-archiving and/or Open Access.

Research limitations/implications

Brazilian universities were excluded owing to the researchers' language limitations. Data were collected between September 15 and 30, 2019, so it represents a snapshot of information available at that time. The study was limited to an analysis of library websites using a fixed set of keywords, and it did not investigate whether other campus units were involved or whether other methods of informing researchers about predatory publishing were being used.

Originality/value

The study reveals some best practices leading to recommendations to help academic libraries combat predatory publishing and improve scholarly publishing literacy among researchers.

Abstract

Purpose

This paper aims to investigate whether and to what extent equity crowdfunding (ECF) is able to build enduring businesses. This research explores the post-campaign growth of equity-crowdfunded companies and analyses the impact of intellectual capital (IC) on their growth. To achieve the above aim, we provide a theoretical framework that includes the three well-known dimensions of IC – i.e. human, structural and relational capital – as independent variables and company growth, meant as sales and employment growth, as dependent variable.

Design/methodology/approach

This research uses a quantitative methodology based on two regression analyses. The authors use hand-collected data on 51 successful equity-crowdfunded projects listed on seven Italian platforms.

Findings

The authors find that three variables, namely prior industry experience (human-capital), product innovation (structural-capital) and equity offered (relational-capital) are significant and positively related to the growth of equity-crowdfunded companies. In particular, prior industry experience positively influences sales growth; product innovation positively influences employment growth. Equity offered, instead, has a strong positive impact on both sales and employment growth. Companies that offer a larger percentage of equity during the campaign disclose higher probabilities of growth.

Practical implications

The study has useful implications for several stakeholders, in particular, founders, platform managers, crowdfunders, policy makers and authorities.

Originality/value

The results shed some light on the nascent research field related to post-campaign scenarios of equity-crowdfunded companies. This paper is the first to explore the impact of IC on the growth of companies funded through ECF.
