waveformlidar: An R Package for Waveform LiDAR Processing and Analysis
Authors: Zhou Tan , Popescu Sorin
Published: May 2019

A wealth of Full Waveform (FW) LiDAR data are available to the public from different sources, which is poised to boost the extensive application of FW LiDAR data. However, we lack a handy and open source tool that can be used by potential users for processing and analyzing FW LiDAR data. To this end, we introduce waveformlidar, an R package dedicated to FW LiDAR processing, analysis and visualization as a solution to the constraint. Specifically, this package provides several commonly used waveform processing methods such as Gaussian, adaptive Gaussian and Weibull decompositions, and deconvolution approaches (Gold and Richard-Lucy (RL)) with users’ customized settings. In addition, we also developed functions to derive commonly used waveform metrics for characterizing vegetation structure. Moreover, a new way to directly visualize FW LiDAR data is developed through converting waveforms into points to form the Hyper Point cloud (HPC), which can be easily adopted and subsequently analyzed with existing discrete-return LiDAR processing tools such as LAStools and FUSION. Basic explorations of the HPC such as 3D voxelization of the HPC and conversion from original waveforms to composite waveforms are also available in this package. All of these functions are developed based on small-footprint FW LiDAR data, but they can be easily transplanted to the large footprint FW LiDAR data such as Geoscience Laser Altimeter System (GLAS) and Global Ecosystem Dynamics Investigation (GEDI) data analysis. It is anticipated that these functions will facilitate the widespread use of FW LiDAR and be beneficial for better estimating biomass and characterizing vegetation structure at various scales.

Published: May 2019

Poly(hydroxyalkanoates) (PHAs) are currently considered competent candidates to replace traditional plastics in several market sectors. However, commercial PHA grades exhibit unsatisfactory smell that can negatively affect the quality of the final product. The cause of this typical rancid odour is attributed to oxidized cell membrane glycolipids, coming from Gram negative production strains, which remain frequently attached to PHAs granules after extraction. The aim of this research is the development of customised PHA nano-biocomposites for industrial applications containing organo-modified nanoclays with high adsorption properties able to capture volatile compounds responsible of the displeasing fragrance in PHAs. To this end, a methodology for the detection and identification of the key volatiles released due to oxidative degradation of PHAs has been established using a headspace solid-phase microextraction technique. We report the development of nine nano-biocomposite materials based on three types of commercial PHA matrices loaded with three species of nanoclays which represent a different polar behaviour. It has been demonstrated that although the reached outcome effect depends on the volatile nature, natural sepiolite (T2) might result in the most versatile candidate for all PHA matrices selected.

Phytostabilization of Zn and Cd in Mine Soil Using Corn in Combination with Manure-Based Biochar and Compost
Authors: Sigua Gilbert , Novak Jeff , Watts Don , Ippolito Jim , Ducey Thomas , Johnson Mark , Spokas Kurt
Published: May 2019

Mining activities could produce a large volume of spoils, waste rocks, and tailings, which are usually deposited at the surface and become sources of metal pollution. Phytostabilization of the mine spoils could limit the spread of these heavy metals. Phytostabilization can be enhanced by using soil amendments like manure-based biochar capable of immobilizing metal(loid)s when combined with plant species that are tolerant of high levels of contaminants while simultaneously improving properties of mine soils. However, the use of manure-based biochar and other organic amendments for mine spoil remediation are still unclear. In this greenhouse study, we evaluated the interactive effect of biochar application and compost on shoots biomass yield (SBY), roots biomass yield (RBY), uptake, and bioconcentration factor (BCF) of Zn and Cd in corn (Zea mays L.) grown in mine soil. Biochar sources (BS) consisted of beef cattle manure (BCM); poultry litter (PL); and lodge pole pine (LPP) were applied at 0, 2.5, and 5.0% (w/w) in combination with different rates (0, 2.5, and 5.0%, w/w) of cattle manure compost (CMC), respectively. Shoots and roots uptake of Cd and Zn were significantly affected by BS, CMC, and the interaction of BS and CMC. Corn plants that received 2.5% PL and 2.5% BCM had the greatest Cd and Zn shoot uptake, respectively. Corn plants with 5% BCM had the greatest Cd and Zn root uptake. When averaged across BS, the greatest BCF for Cd in the shoot of 92.3 was from the application BCM and the least BCF was from the application of PL (72.8). Our results suggest that incorporation of biochar enhanced phytostabilization of Cd and Zn with concentrations of water-soluble Cd and Zn lowest in soils amended with both manure-based biochars while improving biomass productivity of corn. Overall, phytostabilization technique and biochar application have the potential to be combined in the remediation of heavy metals polluted soils.
Euglena Central Metabolic Pathways and Their Subcellular Locations
Authors: Inwongwan Sahutchai , Kruger Nicholas J. , Ratcliffe R. George , O'Neill Ellis C.
Published: May 2019

Euglenids are a group of algae of great interest for biotechnology, with a large and complex metabolic capability. To study the metabolic network, it is necessary to know the subcellular locations of the component enzymes, but despite a long history of research into Euglena, the subcellular locations of many major pathways are only poorly defined. Euglena is phylogenetically distant from other commonly studied algae, they have secondary plastids bounded by three membranes, and they can survive after destruction of their plastids. These unusual features make it difficult to assume that the subcellular organization of the metabolic network will be equivalent to that of other photosynthetic organisms. Moreover, we show here that the presence of the secondary chloroplast means that it is not possible to make reliable predictions of the subcellular locations of enzymes in Euglena using existing informatics tools. In order to generate a model of the central metabolic pathway operating in Euglena we analysed biochemical and proteomic information from a variety of sources to assess the subcellular location of relevant enzymes. We use these assignments to propose the compartmentation of the core metabolic pathways in Euglena, a prerequisite for the further study of the metabolic network of Euglena. This model of the metabolic network shows that, other than photosynthesis, all major pathways present in the chloroplast are duplicated elsewhere in the cell, and that several biosynthetic pathways confined to plastids in higher plants are localized elsewhere in Euglena. Our model demonstrates how this organism can synthesise all the metabolites required for growth from simple carbon inputs, and can survive in the absence of chloroplasts.

Published: May 2019

A Wireless Body Area Sensor Network (WBASN) is combination of numerous sense nodes, positioned onto/close or inside a person body. Wireless Body Area Sensor Networks (WBASN) is a developing automation trend that exploits wireless sensor nodes to put instantaneous wearable well-being of ill person to improve individual’s existence. The sensor nodes might be used outwardly to observe abundant health parameters (like heart activity, blood pressure and cholesterol) of an ill person at a vital site within hospital. Hence the goal of WBASN is much crucial, enhancing the lifetime of nodes is compulsory to sustain many issues such as utility and efficiency. It is essential to evaluate time that when the first node will die it we want to refresh or change the battery reason is that loss of crucial information is not tolerable. The lifetime is termed as the time interval when a first node dies out due to battery exhaustion.  In our proposed protocol life time of a network is the main concern as well other protocol related issues such as throughput, path loss, and residual energy. Bio-sensors are used for deployment on human body. Poisson distribution and equilibrium model techniques have been used for attaining the required results. Multi-hop network topology and random network node deployment used to achieve minimum energy consumption and longer network lifetime.
Variability and Reproducibility of Directed and Undirected Functional MRI Connectomes in the Human Brain
Authors: Conti Allegra , Duggento Andrea , Guerrisi Maria , Passamonti Luca , Indovina Iole , Toschi Nicola
Published: May 2019

A growing number of studies focus on methods to estimate and analyze the functional connectome of the human brain. Graph theoretical measures are commonly employed to interpret and synthesize complex network-related information. While resting state functional MRI (rsfMRI) is often employed in this context, is known to exhibit poor reproducibility, a key factor which is commonly neglected in typical cohort studies using connectomics-related measures as biomarkers. We aimed to fill this gap by analyzing and comparing inter- and intra- subject variability of connectivity matrices as well as graph-theoretical measures in a large (n=1003) database of young healthy subjects which underwent four consecutive rsfMRI sessions. We analyzed both directed (Granger Causality and Transfer Entropy) and undirected (Pearson Correlation and Partial Correlation) time-series association measures and related global and local graph-theoretical measures. While matrix weights exhibit a higher reproducibility in undirected as opposed to directed methods, this difference disappears when looking at global graph metrics and, in turn, exhibits strong regional dependence in local graphs metrics. Our results warrant caution in the interpretation of connectivity studies, and serve as a benchmark for future investigations by providing quantitative estimates for the inter- and intra- subject variabilities in both directed and undirected connectomic measures.
Population Dynamics of Spotted Wing Drosophila (Drosophila suzukii Matsumara) in Maine Wild Blueberry (Vaccinium angustifolium Aiton)
Authors: Drummond Francis , Ballamn Elissa , Collins Judith
Published: May 2019

A long-term investigation of D. suzukii dynamics in wild blueberry fields from 2012 - 2018 demonstrates relative abundance is still increasing seven years after initial invasion. Relative abundance is determined by physiological date of first detection and air temperatures the previous winter. Date of first detection of flies does not determine date of fruit infestation. The level of fruit infestation is determined by year, fly pressure, and insecticide application frequency. Frequency of insecticide application is determined by production system. Non-crop wild fruit and predation influences fly pressure; increased wild fruit abundance results in increased fly pressure. Increased predation rate reduces fly pressure, but only at high abundance of flies, or when high levels of wild fruit are present along field edges. Male sex ratio might be declining over the seven years. Action thresholds were developed from samples of 92 fields from 2012 - 2017 that related cumulative adult male trap capture to the following week likelihood of fruit infestation. A two-parameter gamma density function describing this probability was used to develop a risk-based gradient action threshold system. The action thresholds were validated from 2016-2018 in 35 fields and were shown to work well in two of three years (2016 and 2017).

Overt and covert: Successful strategies for building employability skills of vocational education graduates
Authors: Fraser Cath Jane , Duignan Gerard , Stewart Deb , Rodrigues Agustilia
Published: May 2019

Knowing how well higher education providers prepare learners for the working world is becoming increasingly important at all programme levels, and this is nowhere more apparent than with vocational education training. Ensuring our learners can hit the ground running and become immediately productive is essential for the relevance, and probably the survival, of New Zealand’s Institutes of Technology and Polytechnics (ITPs). Yet while there is much commentary about the challenges of transitions from tertiary study into employment and the ‘employability skills gap’, there is all too little given to how this is being addressed in teaching. This paper describes the work of an inter-institutional research collaboration into current approaches being used to embed skills that enhance employability. Drawing on a number of frameworks and models, the research team selected ten core attributes: positive attitude, communication, teamwork, self-management, willingness to learn, thinking skills, resilience, innovation, entrepreneurship and cultural competence. The team then identified a range of strategies being used by highly commended teachers to enhance the ten employability skills: firstly, by observing classroom and online practices of 23 selected teachers from participating organisations; and secondly through follow-up interviews with the same teachers. The key takeaway of this research is raised awareness and intentionality of the overt and covert approaches vocational educators are using to enhance the employability of their students.

Published: May 2019

Background: To compare the effectiveness of intravitreal ranibizumab (IVR) injections for the treatment of diabetic macular edema (DME) in eyes with and without previous vitrectomy.
Methods: The medical records of 30 eyes (13 vitrectomized, 17 nonvitrectomized) of 28 patients (mean age, 59.09.6 years; male to female ratio 1:1) who were diagnosed with DME and had received IVR treatment were reviewed retrospectively. The best-corrected visual acuity (BCVA), central macular thickness (CMT), and total macular volume (TMV) were measured at baseline and at months 6, 12, 18, and 24 of the follow-up. The number of IVR injections, the duration between diagnosis of DME and IVR injection, and hemoglobin A1c (HbA1c) level at baseline were also recorded.
Results: Baseline demographics, HbA1c, BCVA, CMT, and TMV values were similar between the vitrectomized and nonvitrectomized groups (p>0.05). The duration between diagnosis of DME and IVR injections was longer in the nonvitrectomized group than in the vitrectomized group (165 years vs. 134 years, respectively; p=0.045). IVR injection was performed 6.3 times in vitrectomized eyes and 6.1 times in nonvitrectomized eyes during the 24-month period (p>0.05). BCVA improved significantly during the 24-month period in both groups. The improvement in BCVA was significant at month 6 in nonvitrectomized eyes, while there was no significant improvement in vitrectomized eyes before month 18. Compared to the baseline values, the decrease in both CMT and TMV was significant in months 6, 12, 18, and 24 in the nonvitrectomized group (p<0.05). In the vitrectomized group both CMT and TMV improved significantly only in months 18 and 24 (p<0.05).
Conclusion: IVR treatment for DME is equally effective in both vitrectomized and nonvitrectomized eyes. However, the response to treatment is seen later in vitrectomized eyes compared to nonvitrectomized eyes.

Published: May 2019

Background: The gut microbiota plays multiple critical roles in maintaining the health of the host, especially in ruminants; however, our understanding of the process of gut microbiota establishment from birth to adulthood remains limited. Here, we investigated the bacterial ecology in the gastrointestinal segments (rumen, abomasum, duodenum and rectum) of Holstein cows from 1 week to 5 years of age by 16S rRNA gene sequencing to illustrate the dynamic establishment of gastrointestinal microbiota of cows.
Results: We revealed a major change in the composition, diversity, and abundance of bacteria with age increase. Remarkably, the gut bacterial community was found to be age-discriminatory, and microbiota gradually matured in each segment of the gut which followed a natural logarithmic function by applying a maturity index algorithm, that meant gut microbiota was established quickly in young animals, then slowed with age. Using the Bayesian algorithm of Source-Tracker, we demonstrated that the proportion of bacterial transfer from the foregut to the hindgut was also higher in young animals, and then decreased sharply with age.
Conclusions: Our findings demonstrated gastrointestinal microbiota was established quickly during young period of cows and highlighted the “window period” of 18 weeks after birth for cows to establish their gut bacterial community. This insight into gut microbiota might have important ecological applications in protecting gut health or manipulating the gut microbiota of cows.
Curiosities above c = 24

Two-dimensional rational CFT are characterised by an integer
\ellℓ,
related to the number of zeroes of the Wronskian of the characters. For
two-character RCFT’s with \ell<6ℓ<6
there is a finite number of theories and most of these are classified.
Recently it has been shown that for \ell\ge 6ℓ≥6,
there are infinitely many admissible characters that could potentially
describe CFT’s. In this note we examine the
\ell=6ℓ=6
case, whose central charges lie between 24 and 32, and propose a
classification method based on cosets of meromorphic CFT’s. We
illustrate the method using theories on Kervaire lattices with complete
root systems. In the process we construct the first known two-character
RCFT’s beyond \ell=2ℓ=2.

Published: May 2019

Os freqüentes relatos de insucesso na indução de associação de empresas vêm colocando em cheque as premissas tradicionalmente adotadas em estratégias associativas, pois em geral partem da premissa de que o imperativo é tecnológico, mesmo que não denunciem explicitamente esta percepção e orientação da escolha. O presente trabalho busca organizar, desta forma, um quadro teórico de referência para a discussão do modelo de redes baseado na necessidade da redefinição institucional. Entende-se instituição como estruturas de relacionamento estabelecidas por acordo social, com caráter de relativa permanência e identificável pelo valor e eficácia de seus códigos de conduta, em grande medida expressas formalmente em diplomas legais. Prevêem estas orientações institucionais a autonomia dos atores participantes e o acordo livre de vontades. Trabalhando, fundamentalmente, com o conceito de confiança e economia institucional, estimula a revisão dos trabalhos que apresentam casos de sucesso em formação de redes de organizações, bem como sugere o uso dos casos de insucesso como objeto de entendimento do fenômeno de intensificação da formação de redes.

Authors: Mindetbay Yerkhan , Bokhove Christian , Woollard John
Published: May 2019

This study investigates the relationship between computational thinking performance and general school achievement and explores to see if computational thinking performance can be predicted by algebra and informatics achievement. The sample group of 775 grade 8 students was drawn from 28 secondary schools across Kazakhstan. The students responded to a Computational Thinking Performance test of 50 multiple-choice questions and Computational Thinking Scale questionnaire. The test covers the concepts: logical thinking, generalisation and abstraction. The validity and reliability of the multiple-choice questions are tested using the Item Response Theory. The Likert type questionnaire covers five factors: creativity, algorithmic thinking, cooperation, critical thinking and problem solving. School achievement results (secondary data) include scores for a number of school subjects. The results of the study showed that the multiple-choice questions are valid and a reliable tool to measure computational thinking performance of students. Algebra, general school achievement and students’ perception of their computational thinking skills were significant predictors of computational thinking performance. The results revealed no gender difference in computational thinking performance and perceptions of computational thinking. The findings regarding the relationship between computational thinking performance, the students’ general school achievement and perceptions of computational thinking skills are compared and discussed.
The Role of School Leadership in the Implementation of Programming and Stem Concepts into Classroom Practice
Authors: Sari Serpil Tuti
Published: May 2019

This short practitioner report discussed the role of the school leadership in the implementation of programming, and STEM concepts into classroom practice in an educational institution in Izmir, Turkey. The study investigated the process of how the school's leadership team including the ICT coordinator made it possible to integrate these relatively new concepts into the school’s curriculum by effectively managing the change process. 50 teachers from different fields including early years, primary, history, science, mathematics, computing, visual arts, and English, were active participants in the implementation program and were asked to regularly reflect on their experiences. The data from the teacher’s reflective journals showed that both programming and STEM concepts were seamlessly integrated into the schools’ curricula and classroom practice. The teachers reported that by receiving training about these concepts and the tools that are necessary for teaching them, was beneficial for supporting the student’s development of 21st-century learning skills such as collaboration, communication and problem-solving. They also explained how the supportive attitude of the leadership team which provided time, resources and training opportunities for teachers, had an impact on the teachers' attitude towards the change process.
Integrating Design and Planning in Informal Settlements
Authors: Parmar Manoj , Singh Binti
Published: May 2019

Informal settlements are often not included in the development plan of cities. Urban planning has increasingly been less concerned about provision of basic infrastructure and services to vulnerable communities living and working in informal conditions. Increasing official apathy pose major challenges to achieving the globally accepted goal of inclusive urbanization as envisaged in Sustainable Development Goals / SDGs.. Goal 11 that aims at creating Safe, resilient, inclusive and sustainable cities will remain distant until we factor in the informal living and working conditions into our current urban planning narrative.GazdharBandh is a Notified Slum by Slum Redevelopment Authority (SRA) of MMRDA (Maharashtra Metropolitan Region Development Authority). The slum pocket is located in western suburb of Santacruz west,  Mumbai. Gazdhar Bandh shows high density informal housing within the “no development zone” as per the development plan 2034,  in estuary conditions that is vulnerable to recurrent floods.Slum upgradation faces multiple challenges with the complex interplay of local diversities, relocation and livelihood concerns. Using the case study of Gazdar Bandh slum, we examine how community responses to housing and other design strategies like public spaces, streetscapes, and makeshift spaces as immediate responses can go a long way to build long term resilience and factored into the broader city level planning narrative. The findings broadly examine the question: How can urban planning and design embrace uncertainty and concludes with an operational framework drawing on participatory planning and good urban place engaging multiple stakeholders.

Published: May 2019

This paper concerns the provision of affordable housing for the poor and needy Muslims through zakat and wakaf funding. The study’s objectives are to determine whether zakat and wakaf resources are employed therein, examine the roles of the zakat and wakaf authorities, and identify constraints and the ensuing strategies. The study was carried out through desk research and interviews with representatives of selected zakat and wakaf authorities. Key findings from the study are that zakat and wakaf are involved in the provision of affordable housing for the poor and needy Muslims and that their funds have been employed therein. However, their roles are dissimilar, therefore, each authority has its own modus operandi. In addition, both zakat and wakaf authorities have constraints in the availability of expertise to undertake the procurement of housing development and they address this problem through collaborative working styles, with each other, and with private property developers.

This research outlines the analysis of income generation basing on agro-cultural tourism of homestays under the purview of Ministry of Tourism and Culture of Malaysia. Using a case study of Kelantan and Terengganu, the research elaborates on the levels of income generated from agro-tourism, distributions, administrations, factors leading to the success of homestays in generating additional income and strategies of infrastructural improvements of homestay. Tourism is one of the largest contributing sectors (13%) to the National Gross Product (RM153 billion) in 2015. Agro-tourism provide opportunities for the visitors to stay and experience the life of an agriculture community in rural areas. Kelantan and Terengganu are rich with agricultural produce, thus have the advantage of showcasing the unique attractions to various tourists’ types. Homestays in Kelantan and Terengganu are limited in research. Hence, this research aims to assess the rural agro-tourism and local community income generated from homestays in Kelantan and Terengganu.

Authors: Falson Jerri
Published: May 2019

Intellectual capital or intangible assets has become widely accepted as one of the most important assets of many of the world's largest companies. However, it is often pointed out that conclusion about valuation in intellectual capital shows a significant difference to capture the potential corporate value activities and determine their future earnings. This paper empirically investigates valuation in the intellectual capital by applying the Analytic Hierarchy Process (AHP) by sorting the non-financial value driver for their weight contributions. It uses topfour industrial sectors in Indonesia which are competing in a distinctive sector to find the observable performance differences. Simultaneously, to complete this research, questionnaires were distributed to valuers in the headquarter of Indonesian Directorate General of State Assets Management (DGSAM). AHP model was used to explore the value weights and ranks among those industries. The findings in this paper are focused on investigating the relative value distribution and determining the diverse patterns across industry by highlighting the importance of intellectual capital to create value advantages.

Malaysia is expected to face ageing population in year 2030. This phenomenon is a challenge that hinders the provision of an excellent environment, including housing them. Active ageing refers to the process of improving the quality of life amongst the elderly in terms of health, social, physical, and environmental aspects. Provision of environment that is conducive and promotion of active surrounding highly influence the elderly to stay active. Nonetheless, literature pertaining to this particular topic area from the stance of elderly Muslims is in scarcity. Hence, the objective of this study is to determine terms associated to active ageing from the Muslim perspective and to identify the appropriate housing environment for them. Data collected from questionnaires distributed to 411 respondents residing in Johor were analysed quantitatively. The outcomes suggest that active ageing amongst elderly Muslims displayed positive effects on spiritual and religious activities. Upon providing housing for them, active ageing is essential so as to perceive active living and exceptional well-being
RESIDENTIAL PROPERTY PRICE HIKE AND SPECULATION
Authors: Haron Razali , Ibrahim Khairunisah
Published: May 2019

This study analyzes the behaviour of property price in Malaysia by examining factors influencing the residential property prices. It aims to determine whether property prices hike in Malaysia can be explained by the fundamental factors or it is due to other unexplained factors, such as speculation. Findings from the study reveal that most of the factors did have significant influence on property price. In addition, the cointegration analysis indicates that the property price and its factors are cointegrated for all property market segments across states. This implies the presence of a long run relationship between the property price and its determining factors, despite slow adjustment of property price towards equilibrium in the long run. This study concludes that the residential property price hike in Malaysia is impacted by fundamental factors and is not speculative in nature.
CAPABILITIES OF REVEALED PREFERENCE METHOD FOR HERITAGE PROPERTY VALUATION
Authors: Mohamad Junainah , Ismail Suriatini
Published: May 2019

In recent years, the increasing availability of large databases on real estate transaction has opened up new research possibilities using revealed preference method. Therefore, the aim of this paper is to investigate the capability of revealed preference method of ordinary least square and rank transformation regression models in valuing shophouse heritage property. This paper has provided the first application that consider the thin market effects by comparing the ordinary least square and rank transformation regression in obtaining the market value of shophouse heritage property. The original dataset consists of 893 commercial properties transacted from 2004 to 2014 in Kota Bharu, Kelantan Malaysia. After filtration process, only 25 units of shophouse heritage property were available and valid to be used. The findings suggest that rank transformation regression model performs better than the ordinary least square model with double-log as the best model. This suggests that rank transformation regression is capable for heritage property valuation in thin market situation.
Investigating the Food and Drug Administration Biotherapeutics Review and Approval Process: Narrative Review (Preprint)
Authors: Bonet Olivencia Samuel , Sasangohar Farzan
Published: May 2019

BACKGROUND

The development, review, and approval process of therapeutic biological products in the United States presents two primary challenges: time and cost. Advancing a biotherapeutic from concept to market may take an average of 12 years, with costs exceeding US $1 billion, and the product may still fail the US Food and Drug Administration (FDA) approval process. Despite the FDA’s practices to expedite the approval of new therapies, seeking FDA approval remains a long, costly, and risky process.

OBJECTIVE

The objective of this paper is to explore the factors and gaps related to the FDA review and approval process that contribute to process inefficiencies and complexities as well as proposed methods and solutions to address such gaps. This paper also aims to investigate the available modeling efforts for the FDA approval process of therapeutic biological products.

METHODS

A narrative review of literature was conducted to understand the scope of published knowledge about challenges, opportunities, and specific methods to address the factors and gaps related to the review and approval of new drugs, including therapeutic biological products. Relevant peer-reviewed journal articles, conference proceedings, book chapters, official reports from public policy professional centers, and official reports and guidelines from the FDA were reviewed.

RESULTS

Of the 23 articles identified in this narrative literature review, none modeled the current FDA review and approval process structure to address issues related to the robustness, reliability, and efficiency of its operations from an external point of view. Although several studies summarize the FDA approval process with clarity, in addition to bringing to light the problems and challenges faced by the regulatory agency, only a few attempts have been made to provide solutions for the problems and challenges identified. In addition, although several reform models have been discussed, these models lack the application of scientific methodologies and modeling techniques in understanding FDA as a complex sociotechnical system. Furthermore, tools and methods to assess the efficacy of the models before implementation are largely absent.

CONCLUSIONS

The findings suggest the efficacy of model-based systems engineering approaches for identifying opportunities for significant improvements to the FDA review and approval process. Using this holistic approach will serve several investigative purposes: identify influential sources of variability that cause major delays, including individual, team, and organizational decision making; identify the human-system bottlenecks; identify areas of opportunity for design-driven improvements; study the effect of induced changes in the system; and assess the robustness of the structure of the FDA approval process in terms of enforcement and information symmetry.
