Authors: Orndorff Randall C. , Weary David J. , Lagueux Kerry M.
Published: January 2018

Geološki vzroki, ki pogojujejo razporeditev in razvoj vrtač na Salem planoti, Ozarki, južno-osrednji Missouri, ZDA, so bili statistično analizirani z uporabo GIS. Geološki vzroki predstavljajo litostratigrafijo, geološko strukturo, površje in globino do talne vode. Obravnavali so področje za točkovne podatke 2.613 vrtač na dveh 30’ × 60’ kartah s 30 m intervali. Izračunali so % pogostosti vrtač za pet litostratigrafskih enot, pri čemer so ugotovili, da je v Jefferson City dolomitu in Roubidoux formaciji največja gostota vrtač. Opravljena je bila analiza žariščne vsote sosedstva, da bi ugotovili, če ima razporeditev vrtač značilnost združevanja v skupine ali značilnost linearnosti, kar kaže na vpliv geološke strukture. Usmerjenost skupin vrtač na SZ se pojavlja vzdolž projekcije prelomne cone Bolivar-Mansfield v južno-osrednjem Missouriju. Večina vrtač na obravnavanem terenu se nahaja na območjih uravnav in na položnih pobočjih, kar je pogosteje kot na močno razčlenjenih področjih. Močna razpokanost v bližini regionalnih prelomnih con lahko pospeši razvoj vrtač na planoti. Razumevanje kraškega sistema je pomembno za boljše urejanje uporabe zemlje v Ozarkih, vključno z ohranjanjem naravnih virov, urejanjem talne vode in varovanjem okolja, še posebno ker raziskani teren vsebuje možne ekonomsko ugodne zaloge Pb in Zn.The geologic controls on the distribution and development of dolines in the Salem Plateau of the Ozark Plateaus Province, south-central Missouri, USA, was statistically analyzed by using a geographic information system. The controls include lithostratigraphy, geologic structure, slope, and depth to water table. Area and point data for 2,613 dolines in two 30’ x 60’ quadrangles were compiled on a 30-meter grid. The percent area of dolines was calculated for five lithostratigraphic units, and it was determined that the Jefferson City Dolomite and Roubidoux Formation have the highest density of dolines. A focal sum neighborhood analysis was performed to determine if the distribution of dolines had any clustering or linearity that may suggest structural control. A northwest alignment of doline clusters occurs along a projection of the Bolivar-Mansfield fault zone in south-central Missouri. Most dolines in the study area occur on the plateau areas and on gentle slopes rather than in the highly dissected areas. Intense fracturing near regional fault zones may enhance doline development on the plateau areas. An understanding of the karst system is important for better landuse management practices in the Ozarks, including conservation of natural resources, ground-water management, and environmental protection, especially because the study area includes potential economic lead and zinc mineralization.
Coastal Speleogenesis and Collapsing by Emptying of Karst Breccia-Pipes on the Marine Cliffs of the Gargano Peninsula (Apulia, Italy)
Authors: Sauro Ugo
Published: January 2018

Razvoj nekaterih jam v obalnih stenah polotoka Gargano je odvisen od prisotnosti kraških brečastih cevi. Če te cevi, ki lahko predstavljajo tudi vodonosnike, prerežejo obalne stene, jih lahko izpraznijo udarni valovi. Na ta način se lahko razvijajo kupolaste jame, ki se včasih odpro na površje. Prispevek predstavlja model geološke in geomorfološke zgodovine, s pomočjo katerega je mogoče razložiti nastanek brečastih cevi in omenjenih jam.In the coastal cliff of the Gargano peninsula the development of some coastal caves is controlled by the presence of breccia-pipes structures. The breccia-pipes, which may host aquifers, when intersected by the cliff are partially emptied by the waves. In this way dome-like caves may develop, which sometimes open to the surface above. A preliminary model of the geological and geomorphological history leading to the formation of the the breccia-pipes and of this type of cave is outlined.

Perspective Uses of Essential Oils in Functional Foods and Antimicrobial Packaging Material
Authors: Malik Tripti
Published: January 2018

Functional foods are recently introduced to assure superior nutritional quality; contain biologically active compounds in defined amounts. These foods have to be effectively packaged and stored in order to prevent microbial spoilage and risk of food borne infections. Recently, food technologists and scientists are formulating the Essential Oil (EOs) containing functional foods. The antibacterial, antifungal, antioxidant and anti-carcinogenic properties of EOs have been proved by a number of researchers. Health conscious consumers prefer natural additives, hence these volatile oils due to their green image can be safely used as a replacement of synthetic preservatives. The shelf life of functional foods can be improved by antimicrobial packaging incorporating EOs and their derivatives in the edible films and coatings. EOs can be easily fabricated as microencapsules and nanoparticles, which increases their stability and solubility. Hence EOs are considered as the most usable additives in future functional foods.

Authors: Hassannayebi Erfan , Sajedinejad Arman , Mardani Soheil
Published: January 2018

The process of disruption management in rail transit systems faces challenging issues such as the unpredictable occurrence time, the consequences and the uncertain duration of disturbance or recovery time. The objective of this chapter is to adopt a discrete-event object-oriented simulation system, which applies the optimization algorithms in order to compensate the system performance after disruption. A line blockage disruption is investigated. The uncertainty associated with blockage recovery time is considered with several probabilistic scenarios. The disruption management model presented here combines short-turning and station-skipping control strategies with the objective to decrease the average passengers' waiting time. A variable neighborhood search (VNS) algorithm is proposed to minimize the average waiting time. The computational experiments on real instances derived from Tehran Metropolitan Railway are applied in the proposed model and the advantages of the implementing the optimized single and combined short-turning and stop-skipping strategies are listed.

Published: January 2018

The safety of rail transportation has always been the top priority for the Federal Railroad Administration (FRA). Legacy technology is still largely relied upon for detection of faults. Modern technology is mostly used to detect a particular railcar rather than to monitor it for problems. Wireless Sensor Network (WSN) technology is being evaluated by the railroads for real-time or near real-time monitoring of the railcar status for timely response to problems and for trend analysis. In this chapter the authors first highlight the importance of freight rail transportation, followed by briefly discussing specific wireless technologies of interest. In particular, the authors present the shortcomings of the ZigBee protocol in the application domain of railcar monitoring. The authors then introduce hybrid technology protocol. Finally, the authors discuss HTNMote, a hardware platform to implement hybrid technology network and present the results of tests showing the benefits of the new protocol and hardware.
Maritime Empty Container Repositioning
Authors: Khakbaz Hossein , Bhattacharjya Jyotirmoyee
Published: January 2018

Maritime shipping containers are important to a number of different industries as they facilitate the reduction of transportation costs. To address the needs of shippers, empty containers need to be repositioned globally between seaports. Since the cost of empty container repositioning (ECR) constitutes a significant element of the total cost of running a global container fleet operation, the problem has been receiving increasing attention from scholars. The diversity of this literature necessitates the development an appropriate classification scheme to identify trends, gaps, and directions for future research. This paper reviews publications on maritime ECR over the last two decades and examines such trends and potential research directions.

Authors: Saluveer Erki , Ahas Rein
Published: January 2018

Contemporary transportation research is seeing a steady incline in the use of new, digital tracking data. The necessity for such new types of data has risen from the continuous growth of society's mobility, the attractiveness of big data, and the need for data that could be collected automatically to be used in developing various monitoring systems. However, introducing new types of data requires the developing and thorough testing of new methodologies. In the current chapter, the authors introduce some methodological issues related to using passive mobile positioning data in transportation research. The Call Detail Records (CDR) and Data Detail Records (DDR) of Mobile Network Operators are a set of data that are automatically recorded and used with increasing frequency by scientists, including transportation researchers and developers of monitoring systems. The authors go on to introduce the Estonian experience in managing such data, spatial and temporal interpolation, the determining of anchor points, and activities responsible for movement. They assess both positive and negative aspects of using passive mobile positioning data and briefly consider legislation and privacy issues in regards to such data.

Authors: Rahman Mohammad Anwar , Pereda Vivian A.
Published: January 2018

Freight transportation and logistics decisions such as modal choice decisions are strategically important for effective supply chain operation and economic benefits. The freight selection logistic is a multi-criteria multi-objective (MCMO) process, crucial for smooth sourcing of materials, cost-effective delivery of products to customers in the right time, at the right quantity. The study discusses the major transport logistics attributes and the order preference by similarity ideal solution (TOPSIS) algorithm as the preferred MCMO model to support comparative ranking among the alternative freights. The entropy weight coefficient method minimizes the subjectivity in the selection of weight of the attribute. This study integrates the entropy technique on TOPSIS platform to improve the freight selection decision. A numerical example illustrates the procedure of the proposed algorithm and ranks the choices among truck, rail, and several intermodal transport combinations (rail/truck and air/truck) in a transportation selection model.

Authors: Vulevic Ana
Published: January 2018

This chapter reviews regional accessibility and relationship between regional accessibility, the logistic infrastructure and regional economic development. The purpose of this chapter is to emphasize the complexity and causality of this relationship. Transport infrastructure is an important policy instrument to promote regional economic development. In addition, development of logistics is a very important part of the transport policy, while accessibility is an important determinant of the attractiveness of regions for logistics activities. Accessibility indicators measure the benefits households and firms in a region enjoy from the existence and use of the transport infrastructure. Economic development may determine transportation needs and lead to infrastructure improvements and accessibility. The theoretically is defined and empirical evidence that transport accessibility suggests that there is a link between the accessibility of the region and its competitiveness and, therefore, regional economic growth.

Implementation of high-speed rail would require the right type of track network system that would need to be maintained and/or built, as necessary. In this chapter, the author recommends that the United States will need to use the Blended or Building Block Approach to develop high-speed rail. He presents several examples of blended infrastructure worldwide for high-speed rail, which would offer a range of tools here in the United States for high-speed rail development.
Are We There Yet?
Authors: Hodges Dennis
Published: January 2018

This chapter addresses a vision of what was, is, and can be. Japan is already 65 years into its passenger rail improvements and modifications. France is just over 35 years and China is eight (8) years into its passenger rail improvements and modifications. Why cannot the United States see the economic and environmental reasons for doing the same in this country? This chapter discusses that and more. The author has attempted to parcel out the whys, what's and where's as to how the United States became so parochial when it comes to passenger rail transportation; why it is so reticent towards moving forward, and what can be done to change the current political and social attitude and climate.

Authors: Rafay Abdul , Khan Arsala
Published: January 2018

This chapter examines the merger of two cellular companies (MOBILINK and WARID) for sustainability in the telecommunication sector of Pakistan. During 2011-2013, WARID faced the news of the possible sales of the company due to falling revenues, constant poor network quality, and lower network coverage in rural areas. In 2014, all telecom players participated in the auction for 3G/4G licenses, but WARID did not participate due to its technology neutral license (TNL). Important decisions were taken in 2014 like launching of 4G/LTE services in major cities, US$500 million investment, increase of tower sites, opening of new regional sales offices. These decisions along with presence of TNL made WARID an attractive target for merger with MOBILINK. In 2016, the formal merger was finalized for benefits like synergies in CAPEX/OPEX, fastest 4G network, network reach to rural areas, roll-out of new services like the internet of things (IoT) and mobile banking. The merger proved successful. During the first quarter of 2017, the company generated PKR 38.7 billion in revenues, up from the same period a year before.

A Multi-Objective Ensemble Method for Class Imbalance Learning
Authors: Emamipour Sajad , Sali Rasoul , Yousefi Zahra
Published: January 2018

This article describes how class imbalance learning has attracted great attention in recent years as many real world domain applications suffer from this problem. Imbalanced class distribution occurs when the number of training examples for one class far surpasses the training examples of the other class often the one that is of more interest. This problem may produce an important deterioration of the classifier performance, in particular with patterns belonging to the less represented classes. Toward this end, the authors developed a hybrid model to address the class imbalance learning with focus on binary class problems. This model combines benefits of the ensemble classifiers with a multi objective feature selection technique to achieve higher classification performance. The authors' model also proposes non-dominated sets of features. Then they evaluate the performance of the proposed model by comparing its results with notable algorithms for solving imbalanced data problem. Finally, the authors utilize the proposed model in medical domain of predicting life expectancy in post-operative of thoracic surgery patients.
Alchimia
Authors: Alves da Veiga Pedro
Published: January 2018

This article provides insights on an experimental artwork using a non-touch interaction interface. It details the use of a generative figurative approach and describes the audio-visual psychological and relational impact on the target-audience, through direct trial, observation and adaptation, in a first-person account, since authorship is shared between article and artwork. Alchimia is an interactive installation in which a single viewer/interactor (i.e.: the one who interacts with the artefact) stands in front of a screen and a webcam, and by facial detection and simultaneous processing of pre-prepared images and sounds, a virtual mirror space of constant audio-visual stimuli is created. The artwork aims at questioning personal representation, focusing on the face, altering the expression and gender, assigning masks, making the facial traits diffuse, mixed, unexpected, in search of another self, while allowing for self-discovery and playfulness – or intimidation – by means of a simple, familiar and almost invisible interface: the webcam.

Authors: Chen Yumei , Zhao Xiaoyi , Rich Eliot , Luna-Reyes Luis Felipe
Published: January 2018

This paper introduces the concept of Group Decision Support Systems (GDSS) as a tool to support emergency management and resilience in coastal cities. As an illustration of the potential value of GDSS, we discuss the use of the Pointe Claire teaching case. Participants in the exercise work in groups to approach the case using four different computer-supported decision models to explore and recommend policies for emergency mitigation and city resilience. The case, as well as the decision models, can be a valuable GDSS tool, particularly in the mitigation stages of the emergency management cycle. We present preliminary results from the use of the case, models and a simulation environment in a graduate course. We finish the paper by presenting our experience as a framework for building more efficient and secure emergency management systems through the use of GDSS.
Smart Cities
Authors: Soe Ralf-Martin
Published: January 2018

This paper introduces a new dimension to conceptualising smart cities – a cross-border approach for heterogeneous cities. There is a mutual agreement between smart city scholars that cities are smart when they reduce silos and enable better flow of data between city functions and services. This paper focuses on the cross-border aspect of smart cities and claims that ICT in cities do not automatically lead to ubiquitous services across the cities. This can even lead to more fragmentation compared to pre-ICT area. A new model for joint digital services in the cross-border cities – the Urban Operating System – is proposed and will be evaluated in context of two Northern European cities with high commuting frequency: Helsinki and Tallinn.
Combining Model Inference and Passive Testing in the Same Framework to Test Industrial Systems
Authors: Salva Sebastien , Durand William
Published: January 2018

Many software engineering approaches often rely on formal models to automate some steps of the software life cycle, particularly the testing phase. Even though automation sounds attractive, writing models is usually a tedious and error-prone task. In addition, with industrial software systems, models are often not up-to-date. Hence, testing these systems becomes problematic. In this context, this article proposes a framework called Autofunk to test production systems by combining two approaches: model generation and passive testing. Given a large set of events collected from a production system, Autofunk combines an expert system, formal models and machine learning to infer symbolic models while preventing over-generalisation. Afterwards, these models are considered to passively test whether another system is conforming to the models. As the generated models do not express all the possible behaviours that should happen, we define conformance with four specialised implementation relations.
Personality Traits and Negotiation Style Effects on Negotiators' Perceptions in a Web-Based Negotiation
Authors: Alves de Moura Jadielson , Costa Ana Paula Cabral Seixas
Published: January 2018

This article investigates the relationship between the prior knowledge of someone's personality traits and negotiation styles in negotiations supported by web-based negotiation support system (NSS) and the negotiator's perception of the usefulness of NSS, ease of use of communication mechanisms, and outcome satisfaction. A distributive negotiation problem between dyads was proposed for participants. The dyadic analyses were performed using the actor-partner interdependence model. As a result, the analyses found significant effects of prior knowledge of information about personality traits and negotiation styles on the negotiator's perception (actor effects) of the usefulness and ease of use of communication mechanisms, and an indirect effect on outcome satisfaction. Significant effects were also found in the relationship between the opponents' perceptions (partner effects) on ease of use of communication mechanisms and prior knowledge about personality traits and negotiation styles, as well as their effects on outcome satisfaction.
Communication Processes of Information Technology Executives in Higher Education
Authors: Hollman Angela K. , Bickford Sonja H. , Lear Janet L.
Published: January 2018

This article seeks to explain the key variables of internal communication processes of information technology executives, specifically chief information officers (CIOs), at higher education institutions. By understanding the key variables that influence the IT communication process, leaders and administrators, such as the CIO, can better communicate with their stakeholders leading to a successful, technology-integrated organization. While others have sought to model this business-IT relationship using communication as one part of a model, this study focuses upon only the CIO communication process adding value to current information technology management literature. This exploratory pilot article offers empirical insights about how CIOs communicate within their own team and up through the executive ranks of an organization. It suggests that CIOs can be divided into two categories; these two categories, keying off of communication variables, appear to directly affect the ultimate success or failure regarding the integration of technology into the mission and vision of the organization.
A rare case of diaphragmatic hernia after cytoreductive surgery and hypertermic intraperitoneal chemotherapy
Authors: Sorrentino Lorena , Cabry Francesca , Serra Francesco , Gelmini Roberta
Published: January 2018

Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is an effective therapeutic approach for selected patients with gastrointestinal and gynecological malignancies with peritoneal spread. The most frequent postoperative surgical complications are anastomotic leakage, digestive perforations, fistulas, intestinal obstruction, abscess and peripancreatitis. This report presents case of a patient with late postoperative diaphragmatic hernia after CRS and HIPEC. A 50- year-old woman previously treated with CRS and HIPEC for a pseudomyxoma peritonei was admitted to our unit with diagnosis of intestinal obstruction. At the CT scan a left diaphragmatic hernia involving the splenocolic flexure was found. Both stripping of the diaphragmatic peritoneum during CRS, sometimes combined with diaphragmatic resection and the heat of HIPEC might be responsible for such complication. The diaphragmatic hernia is rarely diagnosed after CRS and HIPEC. Surgical techniques for repair can be the direct suture of the defect or closure with synthetic or biological tissue, both are possible surgical techniques for repair with a good long term results.
The Canadian Geospatial Data Infrastructure, achieving the vision of the CGDI
Authors:   GeoConnections
Published: January 2018

Developments in information technology over the past decade have exponentially expanded both the need for geospatial information and the access to this information. To meet this demand, the Government of Canada invested $60 million in the GeoConnections
initiative with a goal, among others, of accelerating the development of the Canadian Geospatial Data Infrastructure (CGDI). GeoConnections will come to a close in March 2005, but a plan and roadmap are needed to continue the important work of building the CGDI.
This roadmap provides the direction to achieve the CGDImp;gt;'s vision. The future for the CGDI looks bright, but action, effort, and perseverance will be necessary to make the CGDImp;gt;'s vision a reality. The roadmap complements the vision and architecture work by providing key goals and tasks to
tackle in the short, mid and long term.
The CGDI has matured technologically to the point that we can now explore the issues and opportunities that will shape its final form. Great strides have been made, but refinement and greater participation are needed to ensure a critical mass of geospatial data, services, applications and users. The
CGDImp;gt;'s external and internal environments need to be explored to understand the opportunities and challenges that lie ahead.
The CGDImp;gt;'s success has been founded on strong partnerships with external and internal stakeholder communities. These types of partnerships should continue to play an important part in the future of the CGDI. The CGDI must look to associations, academia, standards organizations, industry and
all levels of government for continued guidance, support and contributions.
The vision for the CGDI is to enable access to the authoritative and comprehensive sources of Canadian geospatial information to support decision making. The mission statement furthers the vision by outlining how a future coordinating organization will need to operate to achieve the vision of the
CGDI.
The CGDImp;gt;'s mission comprises specific objectives. Each objective has corresponding goals that indicate how the CGDI should evolve . These goals also indicate what results need to be achieved. The mission, however, does not explain how to produce these resultsthat role falls to this roadmap and
its goals and tasks.
These goals and tasks can be grouped into four streams: coordination, users, content, and infrastructure. This roadmap identifies goals and tasks for each of these areas to reach the short-, mid-, and long-term milestones established in this document.
In the short term, funding sources and governance issues will remain in the forefront. In the long term, it will be essential to engage new communities of practice and to have most provinces, territories, and several large municipalities contributing data to the CGDI and using the CGDI. Leadership
and technology have been the focus and strength of the CGDI to this point. The next era of the CGDI needs to focus on service delivery and nurturing strong user communities that have the capacity to work with the CGDI.

The bearing performance of steel backed half bearings, bushings, and washers is dependent on the properties and thickness of the lining alloy, the strength and dimensional stability of the steel backing (usually SAE 1010) and the strength of the bond between the lining alloy and the backing. This SAE Information Report is primarily concerned with the properties of the lining alloys used in automotive applications, in particular, the crankshaft bearings of the internal combustion engine.

The National Research Council (2009) emphasized the importance of enhancing the undergraduate experience to better prepare graduates to work in a global economy. The NRC went further to suggest college faculty might need professional development to make appropriate changes. In 2010, as a part of a USDA Higher Education Challenge Grant, eight faculty in agriculture and natural resources from the University of Florida participated in a 14-day faculty abroad experience to Ecuador to explore their discipline in that country. The purpose of this study was to understand the outcomes evident two years after that experience on the faculty participants. Results revealed changes in attitudes, aspirations, knowledge, and behaviors. Changes in attitudes and aspirations included: the importance of international experiences, the benefits of meeting new colleagues, the value in learning from the other participants, the importance of multidisciplinary interactions, credibility, the importance of authentic interactions, and a desire to learn more. Faculty participants in this experience learned about the Ecuadorian context, learned about their discipline, and learned about pedagogy. Behavior changes included: considering the cultural context, focusing more of their work on Latin America, emphasizing study abroad programs, interacting with new people, and teaching others about what they learned in Ecuador.
An Evaluation of the Self-Efficacy Theory in Agricultural Education
Authors: McKim Aaron J. , Velez Jonathan J.
Published: January 2018

This research sought to evaluate the use of the self-efficacy theory in agricultural education. A total of 30 studies, published between 1997 and 2013 using self-efficacy as a theoretical foundation were compiled and analyzed. The findings of these studies were compared to expected outcomes identified by the self-efficacy theory, specifically the positive relationship between Bandura’s four identified self-efficacy building experiences and increased self-efficacy as well as the relationship between self-efficacy and career persistence. This synthesis highlights important considerations for the use of self-efficacy theory in agricultural education, including a shift from mastery experiences to vicarious experiences in the teacher development process and specific considerations for the establishment of social persuasion between cooperating and student teachers. Finally, based on the comparison of past research in agricultural education and self-efficacy theory, recommendations are made for future research that will continue the articulation of this theory in both research and practice within agricultural education.
Agricultural Opinion Leader Communication Channel Preferences: An Empirical Analysis of Participants of Agricultural and Natural Resource Leadership Development Programs

In the information rich society of the 21st century consumers have had access to many different communication channels where they can find information about agricultural topics. Individuals seek information that fulfills their needs and opinion leaders have been identified as a solution to communicating with audiences about complex topics. However, previous research has neglected to focus on the most effective means of communicating with opinion leaders. Using level of opinion leadership as a predictor of communication channel preference within a Uses and Gratifications framework a sample of 3,234 agricultural opinion leaders were surveyed. Descriptive statistics revealed that web pages and meetings are most preferred while Twitter, conference calls, and other communication channels are least preferred amongst agricultural opinion leaders. Furthermore, inferential statistics illuminated the importance of clearly defining an intended audience. Specifically, although opinion leaders are differentiated from non-opinion leaders within their networks there are additional levels of opinion leadership that may warrant consideration when selecting a communication channel.

The ability to evaluate and accurately articulate the outcomes associated with leadership development programs is critical to their continued financial and administrative support. With calls for outcome-based accountability, the need for rigorous evaluation is particularly relevant for those programs administered through the Cooperative Extension Service (CES). Using Bandura’s (1977) Social Learning Theory, a robust evaluation of agricultural leadership development programs administered through the CES in the southern region of the United States was conducted. Several key findings are examined, specifically: program participant demographics match parity requirements for CES programming; program participants are highly satisfied with their program experience; and program participants have held a large number of leadership roles within their communities and industries.
Supervisor Involvement and Professional Development Needs Associated with SAE Programming and Safety

Published: January 2018

This descriptive survey research study sought to gather evidence of school-based agriculture teachers’ perceptions of community supervisor involvement with supervision and planning of students’ Supervised Agricultural Experience (SAE) work activities and safety training professional development needs. Responding teachers indicated they agreed to strongly agreed that secondary agricultural education teachers were highly involved in planning (90.5%, f = 208), student SAE projects but were in less agreement that parents (57.6%, f = 133), and employers (45.0%, f = 104) were highly involved in planning students’ SAE projects. Teachers were more in agreement that parents (62.6%, f = 144) and employers (68.8%, f = 159) were highly involved in supervising students’ SAE projects. The professional development topic with the lowest level of agreement (58.5%) was preparing safety guidelines for SAE programs. Other safety related professional development topics of interest from teachers included chain saw safety, greenhouse safety, ladder safety, and processing equipment. Agricultural education professionals should implement community outreach seminars and curriculum to support teachers’ professional development in engaging community stakeholders to assist teachers with improving safety conditions for student workers. Additional professional development may be dedicated to technical safety training targeted for specific production agriculture hazards. Recommendations for further research are discussed.
Exploring Agricultural Communications Students’ Perceptions of Communication Apprehension and Writing Apprehension in the Classroom

Employers have identified oral and written communications skills to be the most important skills graduates should possess when entering the workforce. In order for faculty to better understand their students’ oral and written communications skills, they should understand what apprehension the students have toward oral and written communications. Specifically, no studies have been found that explore communication apprehension (CA) or writing apprehension (WA) in agricultural communications students. The purpose of this study was to qualitatively explore agricultural communications students’ perceptions of CA and WA. Participants believe agricultural communications instructors set up an environment that is conducive to changing behavior. However, students realized and identified areas of improvement that could help them lower their CA and WA. Recommendations for practice are provided in order to help alleviate CA and WA in agricultural communications students.
