Published: April 2021

Study Design: Prospective case series.Purpose: To assess the corporal morphology of the fused body and adjacent segment conditions.Overview of Literature: It is known that two fused vertebral bodies take the similar shape of the single body with inwaisting, with or without caudal flaring of the fused body, and that the fused body can cause the fusion disease at the adjacent segment that can be a risk factor for potential neurological compromise.Methods: Radiograms of the 11 study subjects (six men and five women), aged 22–90 years who visited the outpatients’ clinic for various neck complaints without trauma history were examined. C4–5 synostosis was an incidental finding in all the subjects.Results: All the fused bodies were inwaisted and had anterior caudal breaking but no interior corporal flaring. Adjacent segment disease was not found in eight patients aged <40 years. Disk degeneration was found at C3–4 and C5–6 in three patients each and at C6–7 in two patients. Disk degeneration was limited to the adjacent segments.Conclusions: Degenerative disk changes are associated with the natural aging process, and the corporal morphology of the fused vertebral becomes inwaisted similar to that in the single vertebrae.
Becoming a global citizen?
Authors: Booth Jane
Published: April 2021

This article will propose a more authentic learning environment for students of the social sciences, one that is not only learner-centred but community-centred. Drawing on the principles of social pedagogy, cultural-based learning, place-based learning and co-production, this article advocates engaging community groups as co-producers in the generation of knowledge, enhancing learning within – and beyond – the university. By not using the community simply as a source of research data or placement opportunities, the curriculum is more likely to produce reflexive graduates better equipped to engage with complex global problems, enhancing their global citizenship and that of the wider community.

On-Beat/Off-Beat
Authors: Swenberg Thorbjörn , Carlgren Simon
Published: April 2021

Audio-visual rhythm can be achieved in a variety of ways, in film as well as in music videos. Here, we have studied human visual responses to video editing with regard to musical beats, in order to better understand the role of visual rhythm in an audio-visual flow. While some suggest that music videos should maintain synchrony in the audio-visual rhythm, and others claim that music videos should be rhythmically loose in their structure, there is a functional aspect of vision and hearing that reacts to the juxtaposition of audio and visual rhythms. We present empirical evidence of cognitive effects, as well as perceptual differences with attentional effects, for viewers watching music videos cut on-beat and off-beat.

The Evolution of Forming “Territories of Traditional Nature Use” in the Sakha Republic (Iakutiia)
Authors: Parlato Nicholas , Fondahl Gail , Filippova Viktoriya , Savvinova Antonina
Published: April 2021

In the struggle of Russia’s Indigenous northerners for greater control over their ancestral lands, the spatiolegal formations known as Territories of Traditional Nature Use (TTPs, using the Russian acronym) have become their most effective tool. TTPs have assumed diverse characteristics across Russian regions in response to the evolution of federal and sub-federal law and of center-periphery relations at national and regional scales. In the Sakha Republic (Iakutiia), TTP formation is entangled with wider territorial politics and economic trends, which have led to the precarious but powerful advancement of Indigenous rights. This article explores this evolution by comparing the creation of two neighboring TTPs, formed eight years apart under distinct political and legislative conditions. A combination of local efforts, subnational legislative and economic initiatives, and reaction to federal overstep have compelled the improvement and systematization of Indigenous rights in the republic.
Spiritual Dimensions in Exploring the Human-Geosphere Relationship under a Values-Based Approach in Lake Turgoyak, Southern Urals, Russia
Authors: Bellaubi Francesc
Published: April 2021

Surrounded by mountains and forests, Lake Turgoyak in the Southern Urals (Russia) is a popular tourist destination. However, the many resorts and camps as well as the high number of visitors have had a negative environmental impact on the lake. Taking Lake Turgoyak as a case study, the research examines the values in the human-geosphere relationship, framed as a geoethical dilemma revisiting the concept of the noosphere. The formulation of geoethical dilemmas, as a way to explore the values that underpin the technocratic artifacts on which humans relate to the geosphere, reveals a spiritual dimension that shapes cultural identities that, in turn, unfold in eco-ideologies of resistance in hope.

Authors: Mustofa Khairul , Primadiyono Yohanes
Published: April 2021

COP on a cooling machine is used to reveal the performance of a cooling engine. To increase the COP value in the system, it can be done by changing the dimensions of the filter-drier and capillary pipes used. Therefore, this study was conducted to determine the effect of changing the dimensions of the filter-drier and capillary pipe on the COP and the consumption of electrical power produced by the 2-door refrigerator unit. The method used was an experimental method, namely by varying the filter drier and capillary tube dimensions of the 2-door refrigerator. Variations of filter driers used were filter driers with sizes 7 cm and 9 cm. While the capillary pipes used were 0.31 inches in diameter and 0.51 inches in diameter with a length of 200 cm and 250 cm respectively. The results obtained from this study indicate that the greatest COP value is obtained when using a 7 cm filter-drier and a capillary pipe with a diameter of 0.31 inches with a length of 200 cm, which is 2.80. The COP value also continues to decline as the size of the filter-drier and capillary pipes used increases.

Plants are valuable source of polysaccharides that make a large portion of our daily diet. These are natural polymers that are essential to sustain life. They provide high-value nutrition and positively help the immune system and improve the digestive properties. They also help in the elimination of toxic by-products from the human body. Polysaccharides and human health are inextricably linked and intertwined. These are also important components of the cell wall that provides its strength and integrity. Due to their indispensable role in human health, it is very important to know the different modifications and loss of nutritional value during the processing of plant material. Nowadays, these plant-based polysaccharides are used for diverse applications including wound dressing, drug delivery, laxative, cosmetic and pharmaceutical preparations. As an emerging area of plant-based medicines to reduce the side effects of synthetic sources, these polysaccharides are used to enhance the immunogenic response against a specific antigen. This review envisages some important polysaccharides (e.g. mucilages and gums, glycosamine glycans and chitin/chitosan) and their medical, cosmetic, and pharmaceutical applications, with emphasis on the relationship between their structure and function.Keywords: Polysaccharides; Nutrition; Health Functions; Cosmetics; Vaccine; Nutraceuticals

A metaphor-less based AI technique for optimal deployment of DG and DSTATCOM considering reconfiguration in the RDS for Techno-Economic benefits
Authors: Nagaballi Srinivas , Kale Vijay S.
Published: April 2021

The advent of distributed energy resources is undoubtedly transforming the nature of the electric power system. The crisis of conventional energy sources and their environmental effects resulted in the integration of Distributed Generators (DGs) into the distribution system. Simultaneous application of optimum network reconfiguration, DGs, and Distribution Static Compensator (DSTATCOM) unit’s placement in the Radial Distribution Systems (RDS) comes with a raft of technical, economic, and environmental benefits. Benefits include improved power quality, reliability, stability, mitigation of power losses, and voltage profile improvement. In this paper, the combinational process of optimal deployment of DGs and DSTATCOM units in RDS with suitable network reconfiguration to achieve positive benefits has been analyzed. A recent metaphor-less based Artificial Intelligence (AI) technique named the Rao-1 method is employed to overcome this combinational nonlinear optimization problem. The objective functions are to mitigate the power losses, enhance the voltage profile, and voltage stability index of the RDS considering the net economic cost-benefit to the distribution utility. The simulation study of this pragmatic approach problem is carried out on IEEE 33-bus RDS. The comparison of the results obtained by the Rao-1 method with other existing meta-heuristic optimization methods has been made to show its efficacy.

Published: April 2021

With modern economic and social development, the technical and economic requirements of highway maintenance and construction projects have become increasingly complicated. Meticulous and in-depth investigation and demonstration guided by scientific theories and methods are of considerable importance to highway maintenance scheme decision. As basis for the selection of highway asphalt pavement recycling maintenance scheme, the factors influencing the decision are analytically demonstrated and an evaluation system is proposed, including three major decision indexes: applicability of recycling mode, recycled pavement quality recovery index, and economic benefit. According to the principles of data statistics and analysis, this study proposes a calculation method for the recycled pavement quality recovery index, analyzes the economic benefits of decision schemes using economic models such as recycling ratio and cost, and puts forward an optimal evaluation method of engineering cost and its fuzzy score intervals. Index weights are calculated through the analytic hierarchy process, and the comprehensive decision evaluation system and comprehensive evaluation method are established. Subsequently, the decision-making method is analyzed on the basis of the decision system by combining the related data. Results show maximum weight of the pavement quality recovery index and minor differences among four recycling schemes in the quality recovery index and applicability. The decision-making results are simplified with clear hierarchical feature because of the fuzzy score intervals of each index. Findings can provide a reference for the asphalt pavement recycling scheme decision.

Published: April 2021

This manuscript aims to explore the impact of production organization mode on the inventory and delivery rate of pump enterprises and optimize the production management of pump enterprises. The system dynamic model and simulation test method were used to compare the changes in the inventory, productivity and delivery rate of pump enterprise under the traditional make-to-order (MTO) and make-to-stock (MTS) organizational modes. Following the above analysis, the optimized pump order production management mode combined with MTO & MTS was put forward, and the fuzzy comprehensive evaluation method was used to evaluate the three above modes. When customer demand scarcely fluctuates and is easily predictable, the MTO production organization mode can be adopted; when customer demand fluctuates sharply and is difficultly predicted, the MTO & MTS combined mode should be selected. According to the results of the fuzzy comprehensive evaluation, the MTO & MTS mode is the best choice for pump enterprises. Considering that the pump demand is sensitive to the season and natural environment, the optimized mode is suitable for the production and inventory management of pump enterprise.
Athlete’s physiological parameter monitoring system based on K-means and MTLS-SVM algorithm
Authors: Wu Yang
Published: April 2021

In the non-medical model physiological parameter monitoring system, learning the monitoring parameters can improve the diagnostic and prediction accuracy. Aiming at the problems of insufficient information mining and low prediction accuracy in multi-task time series, the supervised and semi-supervised learning methods in machine learning are combined to predict the physiological status of remote health monitoring objects. This method uses the K-means algorithm to cluster the same type of data and use the Multitasking Least Squares Support Vector Machine (MTLS-SVM) to train historical data for trend prediction. In order to evaluate the effectiveness of the method, the MTLS-SVM method is compared with the K-means and MTLS-SVM methods. It can be seen from the experimental results that the body temperature data measured by the GY-MCU90615 is close to that of the digital thermometer. Moreover, the body temperature speed collected by the GY-MCU90615 can reach the millisecond level, which can well meet the needs of the system. The research shows that the method has higher prediction accuracy and has a breakthrough significance for the monitoring of athletes’ physiological parameters.

Authors: Cao Xin-Zi , Luo Sheng-Zhou , Li Jing-Cong , Pan Jia-Hui
Published: April 2021

The grade and stage of bladder tumors is an essential key for diagnosing and treating bladder cancer. This study proposed an automated bladder tumor prediction system to automatically assess the bladder tumor grade and stage automatically on Magnetic Resonance Imaging (MRI) images. The system included three modules: tumor segmentation, feature extraction and prediction. We proposed a U-ResNet network that automatically extracts morphological and texture features for detecting tumor regions. These features were used in support vector machine (SVM) classifiers to predict the grade and stage. Our proposed method segmented the tumor area and predicted the grade and stage more accurately compared to different methods in our experiments on MRI images. The accuracy of bladder tumor grade prediction was about 70%, and the accuracy of the data set was about 77.5%. The extensive experiments demonstrated the usefulness and effectiveness of our method.
Pioneering easy-to-use forestry data with Forest Explorer
Authors: Vega-Gorgojo Guillermo , Giménez-García José M. , Ordóñez Cristóbal , Bravo Felipe
Published: April 2021

Forest Explorer is a web tool that can be used to easily browse the contents of the Cross-Forest dataset, a Linked Open Data resource containing the forestry inventory and land cover map from Spain. The tool is purposed for domain experts and lay users to facilitate the exploration of forestry data. Since these two groups are not knowledgable on Semantic Web, the user interface is designed to hide the complexity of RDF, OWL or SPARQL. An interactive map is provided for this purpose, allowing users to navigate to the area of interest and presenting forestry data with different levels of detail according to the zoom level. Forest Explorer offers different filter controls and is localized to English and Spanish. All the data is retrieved from the Cross-Forest and DBpedia endpoints through the Data manager. This component feeds the different Feature managers with the data needed to be displayed in the map. The Data manager uses a reduced set of SPARQL templates to accommodate any data request of the Feature managers. Caching and smart geographic querying are employed to limit data exchanges with the endpoint. A live version of the tool is freely available for everybody that wants to try it – any device with a modern browser should be sufficient to test it. Since December 2019, more than 3,200 users have employed Forest Explorer and it has appeared 12 times in the Spanish media. Results from a user study with 28 participants (mainly domain experts) show that Forest Explorer can be used to easily navigate the contents of the Cross-Forest dataset. No important limitations were found, only feature requests such as the integration of new datasets from other countries that are part of our future work.
The lengths of spinal curvature stretch due to the angles of sitting on saddle chair to alleviate back pain: A statistical analysis
Authors: Shanmugam Ramalingam
Published: April 2021

BACKGROUND: By dividing the burden of one’s weight between the shins and the buttocks in the sitting position on an office or saddle chair, a person can avoid back pain. In this 21st century, sitting on a chair for long hours in workplace on office chair is unavoidable necessity and hence, millions in different countries undergo a risk for backpain. Is there a right sitting position? OBJECTIVE: The aim of this article is to find out how much a correlation exists between the angle of sitting and the length of spinal curvature which is the source of backpain. An experiment can be designed and carried out to measure various angles in sitting and the changing length of the person’s spinal cord curvature. METHOD: The usual statistical methodology requires a pair of values namely x and y to quantify the correlation. The data on sitting angles and the length of spinal curvature do not have such pairing, and hence, the traditional approach to find the correlation between the sitting angle and length of spinal curvature is not applicable. Yet, an approach is necessary. This article constructs an innovative statistical approach to fulfil this need. RESULTS: Our approach yields a correlation of 0.998 for sitting on office chair and an increased correlation of 0.999 on saddle chair, according to the Truszczyńska-Baszaka et al.’s data. CONCLUSIONS: An adjustment is made in various angles of sitting on office chair to transform the comfortable sitting on a saddle chair. In consequence, the proportional effect on the spinal curvature is estimable with the data and it is phenomenal (that is significantly more than one). No wonder people prefer saddle chair over office chair when it comes to avoid back pain and this article proves the convenience statistically.

A comparison design study of feedback modalities to support deep breathing whilst performing work tasks
Authors: Cochrane Karen Anne , Loke Lian , Ahmadpour Naseem , Schiphorst Thecla , Campbell Andrew , Núñez-Pacheco Claudia
Published: April 2021

BACKGROUND: Deep breathing exercises are known to help decrease stress. Wearable and ambient computing can help initiate and support deep breathing exercises. Most studies have focused on a single sensory modality for providing feedback on the quality of breathing and other physiological data. OBJECTIVE: Our research compares different feedback modalities on an individual’s experience and ability to perform breath-based techniques at work. METHODS: We designed three different interactive prototypes that used light, vibration and sound feedback modalities. We tested each prototype with 19 participants whilst they were performing typical work tasks in a naturalistic setting, followed by semi-structured interviews. RESULTS: We found that sound was the most successful feedback for the majority of participants, followed by vibration and ambient light. We developed an analytic tool, the Extended Cycle of Awareness, to facilitate understanding of the patterns of awareness and the flow of experience generated by participant interaction with prototype systems that provide feedback on the quality of breathing. Participants followed one of three different types of patterns: (1) ignoring the feedback; (2) not understanding the feedback and being overwhelmed by it; (3) successfully using the feedback to initiate deep breathing and reflect on the change in the quality of breathing. CONCLUSIONS: We offer a set of design recommendations for crafting interactive systems to support deep breathing at work, including personalization, designing for the cyclical process of attention and awareness, and designing for reflective practice.

BACKGROUND: Many work-related fatalities happen every year in electricity distribution companies. This study was conducted to model accidents using the time series analysis and survey descriptive factors of injuries in an electricity distribution company in Tehran, Iran. METHODS: Data related to 2010 to 2017 were collected from the database of the safety department. Time series and trend analysis were used for data analyzing and anticipating the accidents up to 2022. RESULT: Most of the accidents occurred in summer. Workers’ negligence was the reason for 75% of deaths. Employment type and type of injuries had a significant relationship (p <  0.05). CONCLUSION: The anticipating model indicated occupational injuries are going to have an increase in the future. A high rate of accidents in summer maybe because of the warm weather or insufficient skills in temporary workers. Temporary workers have no chance to work in a year like permanent workers, therefore acquisition experiences may be less in them. Based on the estimating model, management should pay attention to those sectors of the company where most of the risky activities take place. Also, training programs and using personal protective equipment can help to protect workers in hazardous conditions.

The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified two novel mutant alleles: one for each gene that is responsible for the elevated oleic acid content in four plant introductions. The combination of the newly identified mutant FAD2-1B allele with existing or the novel mutant FAD2-1A alleles created soybean lines with more than 80% oleic acid content. Combination of two mutant FAD2-1A and FAD2-1B with mutant FAD3A or mutant FAD3C or both resulted in high oleic acid content of 80 - 85% and linolenic acid content in the range from 1.5 - 4%. Perfect molecular markers associated with these mutant alleles were designed to help select the soybean lines with genotypes of interest in early generations in breeding. The high oleic acid and high oleic acid low linolenic soybeans produced have an improved stability across growing environments compared to existing sources.

Published: April 2021

This dissertation offers an in-depth case study of the 11-year BP and Greenpeace conflict. A framing analysis of news content from newspapers in the United Kingdom and United States are employed to identify how the two organizations were framed. In-depth interviews with members of the conflicting parties are also included. This study also explores the relationship between crisis communication strategies, corporate reputation, corporate social responsibility, and pro-social messages. As its theoretical contribution, this study proposes a new theory embedded in the media and public relations framework entitled: media attribution theory.
Building better wetlands for amphibians : investigating the roles of engineered wetland features and mosquitofish (Gambusia affinis) on amphibian abundance and reproductive success

Published: April 2021

Compensatory wetland mitigation efforts have been broadly criticized for failing to replace lost ecological functions, even with net gains in wetland area. Of particular concern is the suitability of constructed wetlands as habitat for vulnerable taxa such as amphibians. Habitat loss and alteration are primary reasons for amphibian declines so it is imperative that constructed wetlands significantly contribute to amphibian conservation. I surveyed amphibians in 49 constructed northern Missouri wetlands to investigate influences of wetland design and placement features on amphibian abundance. Features associated with open water ponds best explained abundances of commonly captured species. Salamanders and most hylid frogs were rarely captured and responded positively to aquatic vegetation, but negatively to fish and anthropogenic disturbance-related terrestrial habitat features. I also tested design feature and mosquitofish (Gambusia affinis) effects on amphibian communities in 18 experimental constructed wetlands. Mosquitofish reduced amphibian reproductive success and species richness, and they were a significant cause of ranid tadpole tail injuries. Further, mosquitofish reduced aquatic invertebrate abundance and taxa richness. Vegetation and shallow within-wetland slopes also bolstered abundances of some amphibians, and vegetation increased amphibian and invertebrate richness. Fish-free, heavily vegetated, shallow-sloped wetlands, placed in landscapes with low anthropogenic disturbance, appear to provide the best habitat for conservative amphibian species.
Intrinsic dosimetry : properties and mechanisms of thermoluminescence in commercial borosilicate glass
Authors:   , Clark Richard A.
Published: April 2021

Intrinsic dosimetry is the method of measuring total absorbed dose received by the walls of a container holding radioactive material. By considering the total absorbed dose received by a container in tandem with the physical characteristics of the radioactive material housed within that container, this method has the potential to provide enhanced pathway information regarding the history of the container and its radioactive contents. The latest in a series of experiments designed to validate and demonstrate this newly developed tool are reported. Thermoluminescence (TL) dosimetry was used to measure dose effects on raw stock borosilicate container glass up to 70 days after gamma ray, x-ray, beta particle or ultraviolet irradiations at doses from 0.15 to 20 Gy. The TL glow curve when irradiated with 60Co was separated into five peaks: two relatively unstable peaks centered near 120 and 165 [degrees] C, and three relatively stable peaks centered near 225, 285, and 360 [degrees] C. Depending on the borosilicate glass source, the minimum measurable dose using this technique is 0.15-0.5 Gy, which is roughly equivalent to a 24 hr irradiation at 1 cm from a 48-160 ng source of 60Co. Differences in TL glow curve shape and intensity were observed for the glasses from different geographical origins. These differences can be explained by changes in the intensities of the five peaks. Electron paramagnetic resonance (EPR) and multivariate statistical methods were used to relate the TL intensity and peaks to electron/hole traps and compositional variations.
An intelligent design retrieval system for module-based products
Authors:   , Angkasith Vorapoch
Published: April 2021

The manufacturing industry has shifted its approach from traditional manufacturing to agile manufacturing. The production of customized products will increase in response to the individual demands of customers. In exploring various industry trends, researchers have developed different approaches to designing structural products. The most popular and most commonly used approach in contending with structural products is the modularity approach. Moreover, there are several studies that address modularity with respect to structural representations. Even so, there is not yet a unified method for supporting product structure development and for integrating information. Another aspect that current research has not yet adequately addressed is product information retrieval. Those studies that did contend with product information retrieval, addressed one-level retrieval models, while ignoring structural products. Thus, limitations persist in current intelligent retrieval systems. To answer the aforementioned difficulty, a unified indexing scheme is introduced. In this study, the information can be put into numerical form as the proposed unified indexing scheme, which is represented by a component and structure matrix. The component and structure matrix is the way to achieve an application of modular design retrieval because (1) it is a unique presentation of a structural product and provides a uniform representation; and (2) it lists all modules, as well as all components, in one representation. As a result of the proposed method, an intelligent retrieval system will give an enterprise the ability to communicate with its partners efficiently. Therefore, the aim of this research is to develop a system that will enable more efficient and more effective product-design retrieval systems for structural products, and to demonstrate this framework through a Web-based application using Web technology. To obtain reference designs after utilizing the unified indexing scheme, a Fuzzy-ART neural network is implemented in order to handle retrieval tasks.

Published: April 2021

With the overall goal of
increasing profitability by increasing litter size, two lines of pigs were divergently
selected for four generations on an index of reproductive traits (n = 193 litters). The
selection index (SI) included total born (TB), birth weight (BW) and placental weight (PW)
and was designed to increase (H line) or decrease (L line) BW:PW (placental efficiency; PE).
(Co)variance components were estimated for direct and maternal additive effects by using an
animal model with MTDFREML procedures. Breeding values were estimated (EBV) for individual
BW (n = 2,111), PW (n = 2,006), PE (n = 1,677), and SI (n = 1,677). Direct heritability
estimates were 0.03, 0.25, 0.18, 0.11 and 0.08 for BW, PW, PE, SI, and TB, respectively.
Genetic divergence was 20.7 g, 0.24, 0.11, and 0.07 pigs per generation for PW, PE, SI, and TB, respectively (P less 0.01), but not significant for BW. Thus, PW and PE are susceptible to change by genetic selection; however, the genetic trend for TB unexpectedly was positive in the L line The phase two objective was to evaluate correlated responses in conceptus development and placental function in these lines. Sows were remated within line to produce 50 generation-four litters for evaluation at d 30, 50, 70, 90, and 110 of gestation.Fetal weight did not differ between lines from d 30 to 90, but was lower in H than L at d 110 (P = 0.02). Crown-rump length did not differ between lines from d 30 to 70, but was longer in H than L at d 90 (P = 0.09) and shorter at d 110 (P = 0.04). PW did not differ between lines from d 30 to 90, but was lower in H than L at d 110 (P less than 0.01). PE did not differ between lines at any gestational age. These results suggest that in western breeds, a reduction in placental weight through selection is not accompanied by physiological changes to improve placental function and may result in decreased prenatal survival. The farrowing data were used in phase three to determine factors influencing survival at farrowing (FS) and weaning (WS). These traits were considered traits of the piglet and scored 1 for piglets alive at those time points or 0 if dead. Estimates of direct heritability were 0.16 and 0.18 and of maternal heritability were 0.14 and 0.10 for FS and WS, respectively. Logistic regressions indicated BW, PW, their interaction, and TB can be used as predictors FS and WS. In the presence of BW, PE does not improve the prediction of survival. These results suggest possible selection for increased FS and WS. A piglet's BW, PW, its litter average BW, and the individual's deviation from that average can be used to produce piglets with high survival probability.
Adoption and diffusion of agrobiotechnologies in the US cotton production
Authors:   , Suntornpithug Pasu
Published: April 2021

The study examines the farm level adoption and county level diffusion of three cotton biotechnologies in the US: insect resistant (Bollgard), herbicide tolerance (Roundup Ready), and stacked trait (Bollgard and Roundup Ready). Adoption and diffusion of these cotton biotechnologies are interdependent. A theoretical framework is developed to consider the adoption decision first. An optimal control model explains the effects of various learning mechanisms on the adoption of multiple, interdependent, and divisible innovations. Empirical specifications use a Generalized Method of Moments framework. Farmers are found to simultaneous adopt multiple technologies influenced by perceived economic gains, learning from own experience, and their neighbors' adoption. Other factors also influence adoption decision including: interdependencies among biotechnologies and certain agronomic practices (e.g. minimum tillage). Adoption is found to be scale neutral. Aggregate (county level) models confirm that potential economic gains, learning, innovation interdependencies and complementarities with agronomic practices drive the diffusion of the cotton biotechnologies.
But in the night we are all the same
Authors:   , Hartin-Young Sally
Published: April 2021

But In the Night We Are All the Same, a critical dystopian novel, explores the creation and perpetuation of power structures, gender identity, and desire. The protagonist, Lemon, is a member of the oppressed class. She lives in a nameless city where she and her peers are kept endlessly alive by "hospital machines," a technology that cures every illness and prolongs life. The ruling group (the Those That) uses mindcontrol technologies known as noodles and stroodles to compel the oppressed class to buy the items they see advertised and to make them perform various violent, sexual and degrading acts for the Those That's amusement. Although the people of the city dislike aspects of their lives, most worship and admire the Those That as much as they fear them. Lemon's partner and love interest Astrix, once a member of the Those That, has had his memory erased and must struggle to find out his identity and to come to terms with who he is once he remembers his past. Lemon and Astrix help each other to resist and to determine their identities. Like other modern dystopian novels, this one focuses on an individual's struggle to resist the society and ends with a hopeful conclusion that shows that a better society can exist in the future. Additionally, this novel uses a female protagonist to illustrate the ways in which a person can be oppressed in both gender-specific and non-gender-specific ways. It also illustrates the power structures that lie beneath social systems, and examines how people's desires can be manipulated into a form of social control.
Using attitutudes and motivations to segment the landowner audience: a typology of family forest owners in the Missouri Ozarks and description of management and information behaviors
Authors:   , Richter K. Julie
Published: April 2021

With 74% of Missouri's forestland controlled by family forest owners, understanding this ownership group is important to ensuring the sustainable management of the state's forests. Audience segmentation techniques can help us to understand the diversity of this growing population, and to design effective communication strategies. Cluster analysis was used to construct an attitudinal typology of family forest owners in Missouri based upon responses to a mail questionnaire. Two attitudinal types of family forest owners were identified: legacy owners, for whom the land is an important part of one's personal and family identity, and detached owners, for whom it is not. Attitudinal type was related to management behaviors, with the legacy-oriented owners being more active forest managers than owners with less interest in family legacy. Legacy owners used more sources of information to learn about their land, and were more influenced by other people when making decisions about their woodland.
