Bibliometric analysis of strawberry (Fragaria × ananassa Duch.) research publications from horticulture category based on Web of Science

BACKGROUND: The strawberry (Fragaria × annanasa Duch.) is one of the most significant cash horticultural crops in the world. Fresh strawberry fruits contain dietary fiber, vitamin C, 30-08-2021-carotene, folic acid and other nutrients required for human health and nutrition, and they have an appetizing aroma and flavour, as well as various phytonutrients that may be potentially beneficial to human health and could be used against chronic diseases including cancer and cardiovascular disorders. OBJECTIVE: The current study aimed to identify and analyze the 2,640 article and review type papers of strawberry research from horticulture category based on the Web of Science. METHODS: The Web of Science database was searched to extract data. Bibliometric data, including citation count, were analyzed together with the words by bibliometric science mapping and visualization tools. RESULTS: Papers mainly written in English (2,426, 91.894 %), were from 6,807 authors, 77 countries/territories, 1,504 organizations and published in 57 Journals and book series. Top 5 core journals ranked as Hortscience (360, 13.636 %), Scientia Horticulturae (322, 12.197 %), Journal of the American Society for Horticultural Science (248, 9.394 %), Postharvest Biology and Technology (236, 8.939 %) and Journal of Horticultural Science Biotechnology (134, 5.076 %), that these journals each published more than 134 papers. Top 5 countries and regions were USA, Peoples R China, Japan, South Korea and Brazil. Top 5 organizations were Univ Florida, Univ Calif Davis, USDA ARS, ARS and Michigan State Univ. Top 5 authors are Hancock James F. (Hancock JF), Shaw DV, Chandler Craig K. (Chandler CK), Whitaker Vance M, Choi Jong Myung, each published more than 28 papers. All keywords of the strawberry research from horticulture Category were separated eight clusters for different research topics. CONCLUSIONS: Visualizations offer exploratory information on the current state in a scientific field or discipline as well as indicate possible developments in the future. The review could provide a valuable guide for designing future studies. This work is useful for student identifying graduate schools and researchers selecting journals.

Proposal to Poster: A Model for Individualized Inquiry Based Research Projects in the Context of an Undergraduate Physiology Laboratory Course

Inquiry‐driven learning is a focus of the 2011 Vision and Change Report. A research skill set is important in multiple career paths. It is atypical for undergraduate students to be able to research their own hypothesis, even in a funded lab. We developed a classroom research project to provide this individualized inquiry‐based learning opportunity to all students. As part of a multi‐site trial at Michigan State Univ (MSU) and the Univ of Minnesota Rochester (UMR), students in an upper division physiology course participated in a “Proposal to Poster” project, allowing each student to engage at all levels of the research experience. Students worked in small groups (2‐6) for the first half of the semester to become familiar with available AD Instruments equipment and the scientific method. For the last 9 weeks of the semester, students designed and proposed a unique human physiology research project, wrote an NRSA‐style grant (outline, rough draft, and final draft), recruited subjects, collected/analyzed data over 2‐3 weeks, and presented their human physiology results in a public poster session. After the end of each course, an anonymous survey was given to MSU and UMR students (n=89) using a 5‐pt Likert scale (1 as the worst and 5 as the best). Student satisfaction with this exercise was 4.0 for UMR and 4.5 for MSU. Value of going through the entire process from proposal to poster was 4.1 at UMR and 4.5 at MSU. A common perception of inquiry‐based learning is that individualized independent research is not feasible, although it is highly valued by both students and faculty. Our data demonstrates that this experience is attainable with existing resources, highly valued, and successful across multiple institutions.

Field Research Methods in the Middle East

I n recent years, a growing chorus of voices in the political science discipline has become concerned with the balance among alternative methodological approaches in empirical re search and publications. Accordingly, these scholars have issued a call to further develop and refine rigorous methods for qualitative studies, in contrast to studies that rely on quan titative methods and formal modeling (Bennett, Barth, and Rutherford 2003; Yanow 2003; George and Bennett 2005). My own interest and reason for conducting the following survey is rooted in the observation, even frustration, that the literature on qualitative research meth ods largely focuses on democratic and not on authoritarian regimes or the East in particular.' Research in the East is clearly essential and has received increased attention since the terrorist attacks of 9-11, but given how critical this work is and will con tinue to be in coming years, what are the chal lenges? Do qualitative methodological tools by need to be adapted for Janine A. Clark, research in the University of Guelh ,East? And, if so, how? Broadly speaking, this symposium seeks to address these questions by examining the top ics, techniques, and challenges of scholars con ducting field work in the East, and to elucidate the ways in which they can contribute to the study of qualitative research methods. The experiences of political scientists research ing in the East are especially germane for discussions on qualitative methods, as re searchers must contend with political authori tarianism and violence, anti-Americanism, and presumably deep cultural differences related to religion and, as a result, gender. Given these challenges, how scholars undertake field work in the region, the qualitative methods they use, and how they overcome the obstacles they en counter are of interest and value to political scientists in general. Indeed, a second goal of this symposium is to examine the extent to which Middle Eastern exceptionalism is valid and impacts upon the field research process. Toward these ends, during the 2004-2005 academic year I conducted an email survey of political scientists conducting field research in the East. The qualitative survey had 25 open-ended questions inquiring into: the re spondents' research topics; countries in which they conducted field work; reasons for the choice of countries; types of primary sources utilized in the field; interview techniques; the use of surveys; confidentiality and ethical is sues encountered in the field; anticipated and unanticipated difficulties and the extent to which these were country or region specific; and, the degree to which respondents were well trained for field work by their political science departments (see Appendix 1). The survey was sent out to three list-servers with an exclusive or high percentage of political scientists study ing the East. The first, MESAPOLISCI, is a list run by the East Studies Association (MESA), the North American learned society for schol ars, educators, and those interested in the study of the region. As a constituent society of the American Council of Learned Societies, the National Council of Area Studies Associations, and a member of the National Humanities Alli ance, MESA is the most widely recognized association for the study of the East, with a total membership of over 2,600. Al though, on the one hand, MESA's membership is not wholly inclusive of all academics who study the region and, on the other, it includes n n-academics, MESA's membership directory serves as the most accurate representation of academics studying the East available. A search in the membership base for all mem bers who cite their discipline as political sci ence yields a count of 418. As many political scientists are engaged in research that relies on secondary data available in North America and/or Europe, the number of political scien tists who do field work in the region is smaller. MESAPOLISCI is a list specifically for MESA members who are political scientists and has 140 subscribers. The other two lists to which I sent the survey were: H-MIDEAST-POLITICS@H-NET. MSU.EDU, a network on contemporary E stern affairs based at Michigan State Univer sity with 547 subscribers; and ICAMESNET, a list for East area studies specialists, including political scientists, based at McGill University in Montreal with 157 subscribers. In addition, based on the MESA membership directory, I directly targeted political scientists by sending them the survey to ensure a broad cross-section of responses reflecting seniority (and presumably experience) and countries of research. The degree to which the memberships

True Firs (Abies sp.): New Conifers for the Midwestern Landscape

The genus Abies is a member of the family Pinaceae and consists of approximately 55 species found mainly in upper latitudes or higher elevations in the northern hemisphere. Firs generally prefer cool, well-drained sites with acidic soil. Fir trees are occasionally used as landscape trees but are more commonly grown as Christmas trees. Recently, the Michigan State Univ. Forestry Dept. and the Michigan Christmas tree industry initiated a field test of exotic firs (Abies sp.) for potential use as Christmas trees. In the present study we expanded the evaluation of these exotic fir species to include their suitability as landscape trees and to characterize their tolerance to various environmental stresses. We compared foliar nutrition, gas exchange, chlorophyll fluorescence, and shoot morphology of 23 Abies species and hybrids planted at three horticultural research stations in Michigan. Foliar nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), sulfur (S), boron (B), zinc (Zn), and copper (Cu) were correlated (P &lt; 0.05) with soil pH. Species and hybrids varied (P &lt;0.05) in maximum photosynthetic rate, water use efficiency, chlorophyll fluorescence, and the ratio of total needle area to projected needle area. We will discuss the significance of these traits in relation to selecting trees adapted for use in the Midwestern landscape.

Random Perturbation Methods with Applications in Science and Engineering. Applied Mathematical Sciences, Vol 150

7R3. Random Perturbation Methods with Applications in Science and Engineering. Applied Mathematical Sciences, Vol 150. - AV Skorokhod (Inst of Math, Ukrainian Acad of Sci, 3 Tereshchenkivska St, Kiev, 01601, Ukraine), FC Hoppensteadt (Syst Sci and Eng Res Center, Arizona State Univ, Tempe AZ 85287-7606), H Salehi (Dept of Stat and Probab, Michigan State Univ, E Lansing MI 48824). Springer-Verlag, New York. 2002. 488 pp. ISBN 0-387-95427-9. $79.95.Reviewed by VD Radulescu (Dept of Math, Univ of Craiova, 13, St AI Cuza, Craiova, 1100, Romania).The authors attempt to describe the basic methods and general principles of the theory of random perturbation, as well as some of the main applications of this theory in Mechanics, Engineering, Genetics, and Population Biology. This monograph contains a well-written rigorous mathematical treatment of this subject and deals with modern concepts such as dynamical systems, stochastic processes, stability, Markov chains, population biology, etc. The volume consists of 12 chapters, but the structure of the book is roughly in two parts. The first seven chapters develop several mathematical methods that are useful in the study of random perturbations of dynamical systems. The second part (Chs 8–12) presents nonrandom problems in a variety of important applications. The purpose of Chapter 1 is to describe some basic ergodic theorems (including Birkhoff’s Classical Ergodic Theorem) from a mathematical point of view and to recall some results that will be used in the book. There are also described discrete-time and continuous-time Markov processes, and continuous-time stationary processes. Chapter 2 is devoted to some convergence properties of stochastic processes. Technical conditions that are sufficient for various kinds of convergence are described. The results contained in this chapter are developed mostly in the framework of continuous-time processes. In Chapter 3 the authors develop averaging methods for random perturbations of Volterra integral equations, of differential equations and of difference equations. In each of these cases, the remainder term is considered in greater detail in Chapter 4. The main results in this part of the book establish that the deviation tends to zero in a prescribed sense if an averaging theorem is true. Chapter 5 deals with randomly perturbed systems of differential and difference equations whose averaged systems are static. The main result contained in this chapter establishes that, under some reasonable assumptions, the stochastic process becomes, asymptotically, a diffusion process. Chapter 6 gives an outlook to a variety of stability problems for differential and difference equations when they are perturbed by random noise. The authors also describe the growth of solutions to certain randomly perturbed convolution equations. The abstract results are illustrated by several examples of stability phenomena. Chapter 7 deals with Markov chains having a finite state space, but random transition probabilities. The basic hypothesis is that the transition probabilities of the Markov chain are close to those of a homogeneous Markov chain having nonrandom transition probabilities. Under this assumption, the authors establish the asymptotic behavior of the chain and its transition probabilities. In Chapter 8 it is described a method for studying various kinds of bifurcations for two-dimensional mechanical systems. There are also discussed random perturbations of oscillatory linear systems and of rigid-body motions. In Chapter 9 the authors consider a dynamical system on a two-dimensional torus. The main results involve either flows that have non random elements or random perturbations of problems of this type. In Chapter 10 an important electronic circuit, namely the phase-locked loop is described. It first investigates the circuit’s dynamics without and with random perturbations, but in the absence of external forcing. Next, the response of the circuit to noisy external signals is analyzed. Interesting applications are also given in Chapter 11, in which the authors consider random perturbation of ecological systems, of epidemic disease processes, and of demographic models. Chapter 12 provides several concrete problems from genetics. In both chapters, the authors describe classical models for these phenomena and related results concerning their asymptotic behavior for large time. Appendix A recalls some basic notions of probability theory, and Appendix B contains historical comments and further remarks. In summary, this reviewer would definitely recommend Random Perturbation Methods with Applications in Science and Engineering to those researchers and graduate students in Science and Engineering who require tools to investigate stochastic systems. The book qualifies to be a reference work that certainly would be a valuable addition in libraries of universities and laboratories pursuing research in Applied Mathematics.

Quantifying Stem Elongation in Oriental and Asi-florum Lilies

Our objective was to quantify the stem-elongation patterns of several Oriental and Asi-florum lily cultivars to develop graphical tracking charts where actual crop height can be compared visually against a target growth curve. Oriental lilies (`Mona Lisa' and `Stargazer') were grown in research greenhouses at Michigan State Univ. (MSU) during 1994 and 1995. Asi-florum lily cultivars (`Centurion', `LA-87', `Non-stop', `Salmon Queen', and `Salzburg') were grown at MSU in 1995. Plants received constant 20 °C from emergence to flower in 1995, and constant 15, 18, 21, 24, or 27 °C in 1994. Elongation of Oriental lily plants followed a sigmoid pattern. Oriental lily cultivars elongated rapidly after emergence until 60% of the relative time between dates of emergence and first open flower, at which time plants had achieved ≈82% (`Stargazer') or 85% (`Mona Lisa') of their final height; elongation then exhibited a plateau phase. In contrast to the Oriental lilies, Asi-florum cultivars consistently exhibited a more constant elongation rate throughout the growing period. Simplified graphical tracking curves were developed based on the patterns of elongation and were programmed into a computer decision—support system (`UNH FloraTrack'). The graphical tracking curves were tested by growing `Stargazer', `Mona Lisa', and four Asiflorum cultivars (`Donau', `Dream', `Moneymaker', `Spirit') at the Univ. of New Hampshire and MSU during 1997 to height specifications of 51 to 56 cm (including a pot height of 15 cm). Sumagic growth retardants were applied as a prebulb dip at 5 ppm and as a foliar spray at 3 ppm when plant height was above the target curve. Final height targets were achieved using this method.

Expanding Horticulture Programs through Off-campus Partnerships

Michigan State Univ. (MSU) offers 10 certificate programs through the Institute of Agricultural Technology. These programs are campus based, approximately three semesters in length, and include a professional internship. Efforts were made in horticulture to expand programs into major population centers through joint programs with community colleges. Cooperative agreements were developed with Grand Rapids Community College and with Northwestern Michigan College in Traverse City. Issues addressed in the agreements include recruiting, admissions, advising, financial aid, integration of curriculum from both institutions, distance-learning delivery through the CODEC system, instructional commitments from campus-based and adjunct faculty, procedures for transfer to bachelor's degree program at MSU, and graduation. The symbiotic relationship between the institutions has expanded curriculum opportunities in the local areas, increased accessibility to MSU Horticulture programs, and better serves the nontraditional student. Outreach efforts for academic programs complement the traditional outreach that has occurred through the Cooperative Extension Service.

Effect of Photoperiod on Growth and Fat Accretion in White-Tailed Doe Fawns

The effects of contrasting (16L:8D vs. 8L:16D) photoperiods on fat accretion and growth in 19 white-tailed doe fawns (Odocoileus virginianus) from 9 September to 16 December 1981 were examined. Fawns exposed to long days (LD fawns) delayed their autumn pelage change, whereas those exposed to short days (SD fawns) underwent a normal molt. SD fawns were heavier and accumulated more fat than their LD counterparts. The combined skeletal muscle and viscera of fawns exposed to short daylength contained 1,195 and 2,269 g of fat on 10 November and 16 December, respectively, as compared with 290 and 621 g of fat for LD fawns. SD fawns also had a higher daily intake of feed and were more efficient in converting dietary gross energy into tissue gross energy than LD fawns. Serum prolactin concentrations were substantially lower in SD fawns. Diminishing daylength appears to set the time frame for physiological events associated with fat accretion in white-tailed deer. J. WILDL. MANAGE. 48(3):776-787 Recently, researchers have become interested in evaluating the effects of photoperiod on certain physiological changes that deer undergo annually. Seasonal changes in pelage and feed intake have been linked to changing daylength in red deer (Cervus elaphus) (Pollock 1974, Kay and Ryder 1978). White-tailed deer, responding to an artificially extended summer photoperiod, delayed pelage change, and a decrease from a long day (16L:8D) to a short day (8L:16D) stimulated increased weight gain and sexual maturity (Budde 1983). Antler growth cycles also appeared to be mediated by photoperiod (Goss 1980). It is not clear how photoperiod induces these effects. Many physiological events are under hormonal control. The pineal gland, a light-sensitive organ, may play a role in mediating various hormone concentrations seasonally, thereby implicating changing daylength in circannual endocrine rhythms (Schulte et al. 1981). In domestic ruminants, serum prolactin concentrations follow a seasonal pattern, with lowest concentrations occurring during winter and highest concentrations during summer (Koprowski and Tucker 1973, Tucker et al. 1974). Similar seasonal patterns in prolactin concentrations have been demonstrated in white-tailed deer (Mirarchi et al. 1978, Schulte et al. 1980). Verme and Ozoga (1980) postulated that lipogenesis is mediated by a decline in prolactin and a rise in adrenocorticotrophic hormone, thereby suggesting a possible relationship between decreasing daylength (autumn), decreasing prolactin concentrations, and increased lipogenesis. The objective of this study was to determine the influence of different photoperiods on the growth and fat metabolism of white-tailed doe fawns as measured by 'Present address: Caesar Kleberg Wildlife Research Institute, Texas A&I University, Kingsville, TX 78363. 776 J.

History of Horticulture

Abstract I wish to call attention to a collection of reference notes and citations, now found in the Michigan State Univ. (MSU) Archives, that belonged to the late Fred Bradford. It appears that these handwritten notes had been made by Bradford while on the staff at MSU and later while at the USDA/Plant Introductions, Beltsville, Md. His references and citations on the history of horticulture and plant science are stored in folders, organized by country, and chronologically, more or less. They are written mainly in English, but some are in French or German. They were intended, it seems, for a book which never materialized.

Nutritional health program for high producing dairy herds

Procedures followed to develop a nutritional health programme for dairy clients of the Michigan State Univ. Ambulatory Clinic are outlined. Broadly, the programme includes education of the clients, raising dairy replacements rapidly and economically, forage testing to accurately develop least-cost balanced rations, feeding-management programmes for the lactating and dry cow, and metabolic profile testing to assess the effectiveness of other parts of the programme. Results of the programme are summarized; within 23 Holstein-Friesian and 1 Jersey herd, numbering 1502 cows with average yield of 13 788 lb milk and 560 lb butterfat, occurrence in a 12-month period of nutritionally related diseases (e.g. milk fever, ketosis, displaced abomasum, indigestion, internal parasites, obesity) ranged from 1 to 7%.

Particle Size Index — Breeding Behavior and Association with Protein Percentage in Wheat1

A small‐sample particle size indexing procedure was altered to require only 2.0 g of wheat (Triticum aestivum L. em Thell.) meal per determination. Particle size index (PSI) values were determined on a wide range of materials over a series of experiments and years. High repeatability in duplicate determinations, high correlations between locations, ability to differentiate lines of proven quality acceptance, and relatively low environmental influence indicated its reliance as a measure of kernel texture. A correlation of 0.83 between 56 selected F2 plants and their F3 bulk progenies grown in the subsequent season indicated a high heritability. The divergence of F3 population means resulting from selection of F2 extremes indicated a high degree of response to selection for PSI in early segregating generations. Application of the particle size indexing procedure to breeding materials in the MSU (Michigan State Univ.) hybrid wheat breeding program indicated a large genetic potential for selection. Genotypic and environmental correlations between PSI and protein percentage were small. The possibility of breeding higher protein pastry‐quality soft winter wheat cultivars is discussed.
