Interactive Visual Analytics of Big Data
Authors: Leung Carson K.-S. , Carmichael Christopher L. , Johnstone Patrick , Xing Roy Ruokun , Yuen David Sonny Hung-Cheung
Published: February 2017

High volumes of a wide variety of data can be easily generated at a high velocity in many real-life applications. Implicitly embedded in these big data is previously unknown and potentially useful knowledge such as frequently occurring sets of items, merchandise, or events. Different algorithms have been proposed for either retrieving information about the data or mining the data to find frequent sets, which are usually presented in a lengthy textual list. As “a picture is worth a thousand words”, the use of visual representations can enhance user understanding of the inherent relationships among the mined frequent sets. However, many of the existing visualizers were not designed to visualize these mined frequent sets. This book chapter presents an interactive next-generation visual analytic system. The system enables the management, visualization, and advanced analysis of the original big data and the frequent sets mined from the data.

Debunking Intermediary Censorship Framework in Social Media via a Content Retrieval and Classification Software
Authors: Navanopparatskul Baramee , Sinthupinyo Sukree , Ramasoota Pirongrong
Published: February 2017

Following the enactment of computer crime law in Thailand, online service providers are compelled to control illegal content including content that is deemed harmful or problematic. This situation leads to self-censorship of intermediaries, often resulting in overblocking to avoid violating the law. Such filtering flaw both infringes users' freedom of expression and impedes the business of OSPs in Thailand. The Innovative Retrieval System (IRS) is thus developed to investigate intermediary censorship in online discussion forum, Pantip.com, as a case study of social media. The result shows that there is no consistency of censorship pattern on the website at all. The censorship criteria depend on type of content in each forum. Overblocking is also high, over 70% of removed content, due to intimidation of governmental agencies, lawsuits from business organizations, and fear of intermediary liability. Website administrator admitted that he would cut off some users to avoid business troubles.
Building a Secured XML Real-Time Interactive Data Exchange Architecture
Authors: Rabadi Yousef E. , Lu Joan
Published: February 2017

TCP and UDP communication protocols are the most widely used transport methods for carrying out XML data messages between different services. XML data security is always a big concern especially when using internet cloud. Common XML encryption techniques encrypt part of private sections of the XML file as an entire block of text and apply these techniques directly on them. Man-in-the-Middle and Cryptanalysts can generate statistical information, tap, sniff, hack, inject and abuse XML data messages. The purpose of this study is to introduce architecture of new approach of exchanging XML data files between different Services in order to minimize the risk of any alteration, data loss, data abuse, data misuse of XML critical business data information during transmission; by implementing a vertical partitioning on XML files. Another aim is to create a virtual environment within internet cloud prior to data transmission in order to utilise the communication method and rise up the transmission performance along with resources utilisation and spreads the partitioned XML file (shredded) through several paths within multi agents that form a multipath virtual network. Virtualisation in cloud network infrastructure to take advantage of its scalability, operational efficiency, and control of data flow are considered in this architecture. A customized UDP Protocol in addition to a pack of modules in RIDX adds a reliable (Lossless) and Multicast data transmission to all nodes in a virtual cloud network. A comparative study has been made to measure the performance of the Real-time Interactive Data Exchange system (RIDX) using RIDX UDP protocol against standard TCP protocol. Starting from 4 nodes up to 10 nodes in the domain, the results showed an enhanced performance using RIDX architecture over the standard TCP protocol.
User Query Enhancement for Behavioral Targeting
Authors: Xiong Wei , Wu Y. F. Brook
Published: February 2017

Ad targeting has been receiving more and more attention in the online publishing world, where advertisers want their ads to be seen by potential consumers at the right time. This chapter aims to address the major challenges with user queries in the context of behavioral targeting advertising by proposing a user intent representation strategy and a query enhancement mechanism. The authors focus on investigating the intent based user classification performance and the effectiveness of user segmentation under a topic model that helps explore semantic relation between user queries in behavioral targeting. In addition, the authors propose an alternative to define user's search intent for the evaluation purpose, in the case that the dataset is sanitized.
A Generic Model of Ontology to Visualize Information Science Domain (OIS)
Authors: Sawsaa Ahlam F. , Lu Joan
Published: February 2017

Ontology has been a subject of many studies carried out in artificial intelligence (AI) and information system communities. Ontology has become an important component of the semantic web, covering a variety of knowledge domains. Although building domain ontologies still remains a big challenge with regard to its designing and implementation, there are still many areas that need to create ontologies. Information Science (IS) is one of these areas that need a unified ontology model to facilitate information access among the heterogeneous data resources and share a common understanding of the domain knowledge. The objective of this study is to develop a generic model of ontology that serves as a foundation of knowledge modelling for applications and aggregation with other ontologies to facilitate information exchanging between different systems. This model will be a metadata for a knowledge base system to be used in different purposes of interest, such as education applications to support educational needs for teachers and students and information system developers, and enhancing the index tool in libraries to facilitate access to information collections. The findings of the research revealed that overall feedback from the IS community has been positive and that the model met the ontology quality criteria. It was appropriate to provide consistency and clear understanding of the subject area. OIS ontology unifies information science, which is composed of library science, computer science and archival science, by creating the theoretical base useful for further practical systems. Developing ontology of information science (OIS) is not an easy task, due to the complex nature of the field. It needs to be integrated with other ontologies such as social science, cognitive science, philosophy, law management and mathematics, to provide a basic knowledge for the semantic web and also to leverage information retrieval.

Introduction to Mission Critical Systems and Its Requirements
Authors: Ali Ashraf A. , Al-Begain Khalid
Published: February 2017

In this chapter, the definition of Mission Critical Systems, users, and services will be introduced, then main applications of such system will be listed, the general requirements will be investigated, and finally a distinction between different types of Mission Critical Systems will be briefly discussed. Nowadays, many governmental and non-governmental organizations (NGOs) play critical roles in its operations on everyday basis. The services provided by such organization is of special nature that makes it less tolerant to executional or operational errors; such services are referred as Mission Critical Services. The criticality of the service implies that it has a set of special requirements that distinguish it from other services, and it should be available anytime, anywhere within the service operational scope, and also it is supposed to be functioning within expectation limits regardless of the operational circumstances or running conditions.

Authors: Ali Ashraf A. , Al-Begain Khalid
Published: February 2017

In this chapter analyses the overall system capacity and scalability which is affected by added traffic introduced by more users who are trying to access the system provided services. This could happen in a mission critical communication system during natural disaster or large scale attack, where the system accessibility could be affected due to the sudden increase of number of users. The need for a more detailed study of other SIP and IMS KPIs is vital to have a better understanding of the overall system performance which will enable us to take it a step further toward system performance enhancement and optimization to avoid single point of failure of the system.

Published: February 2017

It is the role of community college leaders to guide their campuses in assessing outcomes for students. Additionally, the diversity of our students requires institutions to significantly improve their effectiveness in educating students who have been underrepresented in higher education. Community colleges must more systematically examine their practice in terms of how students experience the campus and how we can intervene to improve student outcomes. Campus initiatives promoting cultural competence, equity, and social justice cannot be delivered to students in isolation. Faculty and staff diversity must increase, and employees must engage in self-reflection to examine their own assumptions and have courageous conversations about race and ethnicity in higher education. The impetus for these initiatives must come from leadership and be articulated at all levels of the organization. This chapter describes the process used to raise cultural awareness, increase cultural competence, and create an equity mindset at a community college.
Growing Global STEM Learning in Higher Education
Authors: Kennedy Belinda F. , McLaughlin Patricia M.
Published: February 2017

Tomorrow's graduates must make innovative use of global knowledge, universal work-readiness skills, and advanced multicultural understandings to solve future domestic and global problems. However, universities face compelling challenges in providing these skills. Discipline entrenched curricula often takes precedence over global, multicultural learning activities in Science, Technology, Engineering and Mathematics (STEM) disciplines. This chapter reports on the introduction of global competency and cultural awareness into a postgraduate course at an Australian university. The study demonstrates the advantages of using the existing multicultural learner cohort to integrate global competencies and understandings into the curricula. This research showed that teaching activities such as group learning, global problem-based issues and peer assessment, created successful learning interactions amongst domestic and international students. The outcomes highlight the role of academic staff in planning for global competency in STEM classrooms and changing the global mindset of all students.

Developing Intercultural Awareness Within Teacher Preparation Program
Authors: Zhou Wenying , Austin Sheila
Published: February 2017

As more expatriate Chinese language teachers are recruited to teach in American K-12 schools, there is an increasing need for American university teacher preparation programs to address the challenges they are experiencing, as well as how they should cope. With years' experience and a uniquely cross-cultural breadth, this book chapter first examines the cultural differences between the U.S. and China in classroom management, class communication, teaching styles and instructional strategies. To identify the cross-cultural teaching difficulties, as well as the situational and cultural factors that impact the failure of teaching in cross-cultural situations, literature was then reviewed from the fields of teaching Chinese as a foreign language and cross-cultural Chinese language teaching. Last, employing Byram's intercultural competence model, this book chapter suggests ways in which intercultural awareness and intercultural competence be incorporated in higher education foreign language teacher preparation programs in the U.S.
Can Higher Education Really Produce Global Citizens?
Authors: Starr-Glass David
Published: February 2017

Globalization profoundly impacts our economics, societies, and educational systems yet doubt exists in higher education as to an appropriate response. Some colleges have embarked on a process of comprehensive internationalization; others are considering how to graduates global citizens, even although global citizenship remains a deeply contested issue. Considering teaching and learning perspectives, particularly perspectives informed by acquisition and participation metaphors, the chapter critiques higher education efforts to develop global citizenship. It examines inbound international student programs, outbound study abroad initiatives, and changes in learner identification and self-categorization. It argues that while student mobility initiatives have great potential, that potential goes unrealized unless learners have been comprehensibly prepared to engage actively with their new environments and experiences, and to consciously reconsider their identities and self-categorizations.
Fostering Intercultural Identity During Study Abroad to Strengthen Intercultural Competence
Authors: Sol Niki
Published: February 2017

Universities are eager to foster global citizenship within their students, including through study abroad opportunities. However, studying abroad does not necessarily guarantee gains in intercultural competence (Paige & Vande Berg, 2012), especially for the shorter programs that have gained in popularity among university students. This chapter examines the recent literature and argues the need to nurture identity negotiation for students who choose to do part of their higher education abroad; the understanding of one's self is a key component to intercultural competence (Deardorff, 2006). More and more study abroad providers (universities and businesses) have begun to use guided intervention during abroad programs to enhance students' intercultural competence. With careful and intentional pedagogical design, study abroad programs can help students better understand their intercultural identity and become better global citizens.

Using Air to Move Paper Airplanes and Balloon Rockets
Authors: Graybill Letitia
Published: February 2017

This is a case in which students build paper airplanes from templates provided by the instructor as well as those which they design themselves. They extend their ideas on flight by using the principles developed in the paper airplane race to power simulated rockets made out of balloons. They consider such variables as materials, mass and design to see which combination of material design and mass are most effective in constructing an airplane or a rocket that flies the fastest and the furthest in a competition. Contestants are rated on team consideration of variables needing to be controlled in order to have a fair assessment of the designs. When the designs are agreed upon and constructed, a race is conducted. The ideas developed in the paper airplane competition are then used to design a rocket carrying a paper airplane capable of flying across the classroom in the fastest time with the most direct route. This is a simulation of the space shuttle flights. The parameters of the races are developed by the participants.
Coming Out as Transgender or Transitioning Genders
Authors: Corning Michael
Published: February 2017

In recent years, the transgender community has been gaining more awareness and visibility in research, the media, and sociocultural landscapes. Despite this, transgender individuals endure a vast range of personal problems that stem from larger social issues. This chapter will connect the psychological components of identity and the influences of social surroundings to the possible experiences of an individual who comes out as transgender or transitions genders. While many individuals may feel a strong sense of identity affirmation, the interpersonal relationships in his or her life may face a major transitional period as well. This is especially evident in romantic relationships and family dynamics. Outside social stressors or gender transitions could impact the romantic relationship quality and structure of transgender people. Likewise, with family dynamics, the level of family functioning could depend on whether the transgender family member is a parent or child. Conclusively, clinical implications and future directions towards building strong relationships will be explored.

Authors: Lashley Maudry-Beverley , Marshall Vanessa , McLaurin-Jones TyWanda
Published: February 2017

Family interactions play a central role in creating relationships. The dynamic roles of intersectionality and biopsychosocial factors including culture, race, gender and environments stimulate the synergistic effects of relationships. Sociocultural contexts provide meaning to individual lives. The mechanisms within a family dynamic impact the formation of life decisions and overall health, spiritual and mental well-being. The purpose of this chapter is to explain and expand on how many African American women and LGBTQ couples create and interpret family dynamics and romantic relationships; specifically investigating the influential impact of kinship support, the role of the sandwich generation and the occupation of the Black woman as a primary caregiver.
What the Future America Will Look Like
Authors: Yeung Hok Yung Mary
Published: February 2017

This chapter begins with the historical antecedents of interracial dating and marriages (IRM) within the United States and then the increasing rates of IRM in the 21st century. Several forms of discrimination against interracial couples such as racial microaggressions and the transmission of implicit racial attitudes within the family, are analyzed. The Marketplace Economy Theory is also examined. It attempts to explain the existence of IR couples. Theories behind the origins of racism against IRMs are explored. Asian American dating interracially is also discussed. The latter section examines the implications of IRMs for mental health counselors. It provides recommendations of techniques and special therapy styles that may be more effective for IR couples and IRMs during therapy sessions. These techniques (including goal-oriented sessions, based on strengths, psychodynamic approaches, and postmodern approaches) may be more efficacious due to the unique problems IR couples encounter. Suggestions are provided for why further research into biracial and multiracial children is needed.
How Incarceration Affects the Parent-Child Relationship and Family Dynamics
Authors: Ferris Alicia
Published: February 2017

The United States incarcerates more people than any other country in the world (Pew Charitable Trust, 2008). More than one in 100 adults are incarcerated and many of these individuals are parents who have one or more children who are under the age of eighteen. Therefore, 1.7 million children are affected by parental incarceration (Glaze & Maruschak, 2008). Children who have incarcerated parents are exposed to factors that put them at risk for increased delinquency and maladjustment in childhood (Aaron & Dallaire, 2010). Parental incarceration is a heart-wrenching topic, but needs to be discussed because it can negatively impact children and families. Thus, this chapter will explore how parental incarceration affects children and families. Specifically, the various relationships of parent-child, caregiver-child, parent-caregiver, and sibling relationships will be explored. In addition, this chapter will examine the developmental impacts parental incarceration has, legal recommendations, and interventions for children and families affected by parental incarceration.
Yes We Can
Authors: Ives Yossi
Published: February 2017

Most commonly relationship issues are dealt with within a therapeutic framework, which is often appropriate. However, therapy is not always necessary or relevant and it may prevent some people from getting the support they need. This chapter presents pioneering thoughts about the role of coaching in relationship settings, including singles struggling to form or secure a lasting relationship, couples seeking a more satisfying relationship, parents struggling to manage effective relationships with their children, and relationship issues during a midlife crisis. A coaching approach is focused on helping people to identify where the issue lies and to develop strategies to work around it, which can be highly effective in supporting people to achieve many important relationship goals. The chapter begins by setting out the key principles and features of relationship coaching, continues with a summary of key theories particularly relevant to the field, with the remainder of the chapter dedicated to an overview of key applications of relationship coaching combining theory and practice.
Entre o sacerdócio e a pesquisa histórica: a trajetória de Padre Luiz Sponchiado na Quarta Colônia de imigração italiana-RS
Authors: Manfio Juliana Maria , Fernandes Biasoli Vitor Otávio
Published: February 2017

O presente trabalho tem como interesse compreender como Padre Luiz Sponchiado atuou e articulou suas ações nos campos político e cultural em prol da construção de uma “identidade italiana na Quarta Colônia”. Tal espaço localiza-se na região central do Rio Grande do Sul e recebeu imigrantes italianos no final do século XIX. Para desenvolver essa pesquisa, foram analisadas e questionadas as fontes, as quais foram confrontadas com a historiografia da imigração italiana. Utilizou-se especialmente os manuscritos de Padre Luiz Sponchiado, os registros dos livros de genealogia produzidos por ele, suas correspondências, recortes de jornais, entre outros documentos que foram encontrados no Centro de Pesquisas Genealógicas (CPG – Nova Palma), acervo criado e organizado pelo próprio sacerdote. O estudo evidenciou a forma como o pároco construiu a história da Quarta Colônia e como auxiliou na reafirmação de uma identidade italiana, sendo comum entre os moradores dessa região. As discussões da historiografia e o método de análise das fontes permitem entender que a trajetória desse indivíduo tornou-se recurso essencial para reconstituir o contexto histórico da Quarta Colônia, dos acontecimentos e da dinâmica vivida nesse espaço, na medida em que Padre Luiz Sponchiado foi capaz de agir e transformar o local da forma mais oportuna, correspondendo às circunstâncias vividas pelos antigos núcleos de colonização para a reafirmação de uma identidade, com matriz italiana.

Published: February 2017

Samples of gerbils and their potential predators were screened for the presence of Hepatozoon parasites (Apicomplexa: Adeleorina) using both microscopic examination and sequencing of partial 18S rRNA sequences. Positive samples were compared to published sequences in a phylogenetic framework. The results indicate that genets can be infected with Hepatozoon felis. A Cape fox was infected with Hepatozoon canis, whereas the sequence from an infected rodent fell within a group of parasites primarily recovered from other rodents and snakes.
Residents' Procedural Experience Does Not Ensure Competence: A Research Synthesis
Authors: Barsuk Jeffrey H. , Cohen Elaine R. , Feinglass Joe , McGaghie William C. , Wayne Diane B.
Published: February 2017

Background

Many medical certifying bodies require that a minimum number of clinical procedures be completed during residency training to obtain board eligibility. However, little is known about the relationship between the number of procedures residents perform and their clinical competence.

Objective

This study evaluated associations between residents' medical procedure skills measured in a simulation laboratory and self-reported procedure experience and year of training.

Methods

This research synthesis extracted and summarized data from multiple cohorts of internal medicine, emergency medicine, anesthesiology, and neurology resident physicians who performed simulated clinical procedures. The procedures were central venous catheter insertion, lumbar puncture, paracentesis, and thoracentesis. We compared residents' baseline simulated performance to their self-reported procedure experience using data from 7 research reports written by Northwestern University investigators between 2006 and 2016. We also evaluated how performance differed by postgraduate year (PGY).

Results

A total of 588 simulated procedures were performed during the study period. We found significant associations between passing the skills examinations and higher number of self-reported procedures performed (P = .011) and higher PGY (P < .001). However, performance for all procedures was poor, as only 10% of residents passed the assessments with a mean of 48% of checklist items correct (SD = 24.2). The association between passing the skills examination and year of training was mostly due to differences between PGY-1 and subsequent years of training.

Conclusions

Despite positive associations between self-reported experience and simulated procedure performance, overall performance was poor. Residents' clinical experience is not a proxy for skill.
Improving Timely Resident Follow-Up and Communication of Results in Ambulatory Clinics Utilizing a Web-Based Audit and Feedback Module
Authors: Boggan Joel C. , Swaminathan Aparna , Thomas Samantha , Simel David L. , Zaas Aimee K. , Bae Jonathan G.
Published: February 2017

Background

Failure to follow up and communicate test results to patients in outpatient settings may lead to diagnostic and therapeutic delays. Residents are less likely than attending physicians to report results to patients, and may face additional barriers to reporting, given competing clinical responsibilities.

Objective

This study aimed to improve the rates of communicating test results to patients in resident ambulatory clinics.

Methods

We performed an internal medicine, residency-wide, pre- and postintervention, quality improvement project using audit and feedback. Residents performed audits of ambulatory patients requiring laboratory or radiologic testing by means of a shared online interface. The intervention consisted of an educational module viewed with initial audits, development of a personalized improvement plan after Phase 1, and repeated real-time feedback of individual relative performance compared at clinic and program levels. Outcomes included results communicated within 14 days and prespecified “significant” results communicated within 72 hours.

Results

A total of 76 of 86 eligible residents (88%) reviewed 1713 individual ambulatory patients' charts in Phase 1, and 73 residents (85%) reviewed 1509 charts in Phase 2. Follow-up rates were higher in Phase 2 than Phase 1 for communicating results within 14 days and significant results within 72 hours (85% versus 78%, P < .001; and 82% versus 70%, P = .002, respectively). Communication of “significant” results was more likely to occur via telephone, compared with communication of nonsignificant results.

Conclusions

Participation in a shared audit and feedback quality improvement project can improve rates of resident follow-up and communication of results, although communication gaps remained.

Published: February 2017

Background 

There is an incomplete understanding of the most effective approaches for motivating residents to adopt guideline-recommended practices for hospital discharges.

Objective 

We evaluated internal medicine (IM) residents' exposure to educational experiences focused on facilitating hospital discharges and compared those experiences based on correlations with residents' perceived responsibility for safely transitioning patients from the hospital.

Methods 

A cross-sectional, multi-center survey of IM residents at 9 US university- and community-based training programs in 2014–2015 measured exposure to 8 transitional care experiences, their perceived impact on care transitions attitudes, and the correlation between experiences and residents' perceptions of postdischarge responsibility.

Results 

Of 817 residents surveyed, 469 (57%) responded. Teaching about care transitions on rounds was the most common educational experience reported by residents (74%, 327 of 439). Learning opportunities with postdischarge patient contact were less common (clinic visits: 32%, 142 of 439; telephone calls: 12%, 53 of 439; and home visits: 4%, 18 of 439). On a 1–10 scale (10 = highest impact), residents rated postdischarge clinic as having the highest impact on their motivation to ensure safe transitions of care (mean = 7.61). Prior experiences with a postdischarge clinic visit, home visit, or telephone call were each correlated with increased perceived responsibility for transitional care tasks (correlation coefficients 0.12 [P = .004], 0.1 [P = .012], and 0.13 [P =  001], respectively).

Conclusions 

IM residents learn to facilitate hospital discharges most often through direct patient care. Opportunities to interact with patients across the postdischarge continuum are uncommon, despite correlating with increased perceived responsibility for ensuring safe transitions of care.
Discrete element simulation of internal stress in SiCp/aluminum matrix composite prepared by pressureless infiltration
Authors: Liu Bai , Yang Xiaohong , Zhao Zhenyu
Published: February 2017

SiCp / Al-Mg-Si matrix composite was prepared by pressureless Infiltration Process. By discrete element method, microcosmic two-dimensional numerical model of SiCp / Al matrix composites was established and the simulation of the size and distribution of micro-contact pressure and tension was performed from small load to big load until destruction. The results showed that the contact pressure appears the partial focus phenomenon, while the distribution of the contact tension tends to increase. When the calculation loop reaches 170,000 time steps, all the focus areas of contact pressure almost connected, but the contact tension is almost unchanged. At this time, the material closes to destruction. When the calculation loop reaches 210,000 time steps, the contact pressure tends to uniformity, but the distribution of contact tension becomes sparser. The contacts between the discrete units are approximately scattered and the contact tension is close to zero and the contact pressure is evenly even-distributed.Keywords: Aluminum-matrix Composite, SiC, Discrete Element Simulation, Internal Stress
Generalized model for predicting methane conversion to syngas in membrane reactor
Authors: Sinha Rachna , Chauhan Garima
Published: February 2017

Present work aims to provide a conceptual framework for predicting methane conversion efficiency and CO selectivity in a membrane reactor which may assist in selecting the type of membrane and minimizing the cost of syngas production. A comparative evaluation of the performance of ceramic (inorganic) membrane reactors was carried out with other types of synthetic membrane reactors. Data has been taken only from those research papers in which reactor is operating in a temperature range of 800 – 900ºC and the pressure range is 1-2 atm. Linear regression analysis was performed and a generalized equation was developed to predict the methane conversion and CO selectivity using different types of membranes. Simulations were performed using MATLAB ODE45 to investigate feasibility of the developed model. CO selectivity was observed better for ceramic membrane reactors since it achieves 90% saturation in 25 hours while for other synthetic membranes, the conversion is only 10% (approx). Overall, ceramic membrane reactors were found to be better than other synthetic membrane reactor due to effective CO selectivity and CH4 conversion.Keywords: Syngas, CH4 conversion, CO selectivity, ceramic membrane
Determinants of factors influencing technical efficiency of cocoa farmers in Ondo State, Nigeria
Authors: Lawal J.O. , Orisasona T.M.
Published: February 2017

This study examined the factors influencing technical efficiency of cocoa production in Ondo State, Nigeria using a stochastic frontier production function. Using the random sampling technique, well-structured questionnaire were used to elicit information from 120 cocoa farmers in Ondo State, Nigeria. The mean technical efficiency rate attained was at 0.9869 and the elasticity of cocoa production is 1.2134 which indicated that a 1% increase input use will lead to more than one percent proportion change in the output of cocoa. This implies an increasing return to scale in variable inputs use among the farmers. Consequently, the result showed that quantity of chemical used, labour, amount of capital fixed input (naira) and farm size (hectares) significantly influence cocoa production output of farmers.The variables that influenced cocoa farmer inefficiency were age, education levels, secondary occupation, sex and marital status of the farmers.The study recommended that younger farmers be encouraged on the need to take cocoa farming as a business and also be educated to cultivate more hectares of cocoa with which they can grow in age and improve their livelihood.Keywords: technical efficiency, stochastic frontier functions, and cocoa farming in Nigeria

Esta casa, localizada al norte de la ciudad de Mérida, es respuesta a un programa arquitectónico sencillo, pero no por eso deja de ser interesante. Se decidió manejar un sola crujía que ordenara todos los espacios, bajo una sola cubierta, un gran techo, propiciando una apertura al jardín y a la alberca, de donde provienen los vientos dominantes: el oriente. Una serie de estanques acompañan al gran techo, reforzando el carácter lineal de la casa.

Abstract. Based on 8 years of (January 2008–December 2015) cloud phase information from the GCM-Oriented Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Cloud Product (GOCCP), aerosol products from CALIPSO and meteorological parameters from the ERA-Interim products, the present study investigates the effects of atmospheric dynamics on the supercooled liquid cloud fraction (SCF) during nighttime under different aerosol loadings at global scale to better understand the conditions of supercooled liquid water gradually transforming to ice phase. Statistical results indicate that aerosols' effect on nucleation cannot fully explain all SCF changes, especially in those regions where aerosols' effect on nucleation is not a first-order influence (e.g., due to low ice nuclei aerosol frequency). By performing the temporal and spatial correlations between SCFs and different meteorological factors, this study presents specifically the relationship between SCF and different meteorological parameters under different aerosol loadings on a global scale. We find that the SCFs almost decrease with increasing of aerosol loading, and the SCF variation is closely related to the meteorological parameters but their temporal relationship is not stable and varies with the different regions, seasons and isotherm levels. Obviously negative temporal correlations between SCFs versus vertical velocity and relative humidity indicate that the higher vertical velocity and relative humidity the smaller SCFs. However, the patterns of temporal correlation for lower-tropospheric static stability, skin temperature and horizontal wind are relatively more complex than those of vertical velocity and humidity. For example, their close correlations are predominantly located in middle and high latitudes and vary with latitude or surface type. Although these statistical correlations have not been used to establish a certain causal relationship, our results may provide a unique point of view on the phase change of mixed-phase cloud and have potential implications for further improving the parameterization of the cloud phase and determining the climate feedbacks.

Abstract. Chemical composition, microphysical and optical properties of atmospheric aerosol deep inland in the Negev Desert of Israel were found be influenced by daily occurrences of sea breeze flow from the Mediterranean Sea. Abrupt increases in aerosol volume concentration and shifts of size distributions towards larger sizes, which are associated with increase in wind speed and atmospheric water content, were systematically recorded during the summertime at a distance of at least 80 km from the coast. Chemical imaging of aerosol samples confirmed an increased contribution of highly hygroscopic particles during the intrusion of the sea breeze. Besides a significant fraction of marine aerosols, the amount of internally mixed marine and mineral dust particles was also increased during the sea breeze period. The number fraction of marine and internally mixed particles during the sea breeze reached up to 88 % in the PM1-2.5 and up to 62 % in the PM2.5-10 size range. Additionally, numerous particles with residuals of liquid coating were observed by SEM/EDX analysis. Ca-rich dust particles that had reacted with anthropogenic nitrates were evidenced by Raman microspectroscopy. The resulting hygroscopic particles can deliquesce at very low relative humidity. Our observations suggest that aerosol hygroscopic growth in the Negev Desert is triggered by the daily sea breeze arrival. The varying aerosol microphysical and optical characteristics perturb the solar and thermal infrared radiation. The changes in aerosol properties induced by the sea breeze, relative to the background situation, doubled the shortwave radiative cooling at the surface (from −10 to −20.5 Wm−2) and increased by almost three times the warming of the atmosphere (from 5 to 14 Wm−2), as evaluated for a case study. Given the important value of observed liquid coating of particles, we also examined the possible influence of the particle homogeneity assumption on the retrieval of aerosol microphysical characteristics. The tests suggest that sensitivity to the coating appears if backward scattering and polarimetric measurements are available for the inversion algorithm. This may have an important implication for retrievals of aerosol microphysical properties in remote sensing applications.
