Abstract This study utilized unidirectional association score ΔP to track perfective morpheme productivity in longitudinal spoken L2 Italian data. Research questions concerned whether early L2 perfectives were contingent upon telicity of predicates, whether lexeme–morpheme association changed as proficiency increased, and whether distribution of perfectives in the L1 input affected the patterns of morpheme emergence. Results showed that (i) the productive use of the perfective was contingent upon a few, infrequent telic predicates but also upon some actionally underspecified, very frequent general-purpose ones; (ii) a generalized decrease in association scores over time accompanied the productivity of the perfective morpheme; (iii) distribution of perfectives in L2 data did not reflect distribution in the L1 input. The statistical analysis adopted in this study is replicable to other domains where contingency of stem-affix alternations may provide cues for observing the developing L2 grammar

With the intent of summing up the past research on ecodesign and making it more accessible, we gather findings from 106 existing review articles in this field. Five research questions on terminology, evolution, barriers and success factors, methods and tools, and synergies, guide the clustering of the resulting 608 statements extracted from the reference. The quantitative analysis reveals that the number of review articles has been increasing over time. Furthermore, most statements originate from Europe, are published in journals, and address barriers and success factors. For the qualitative analysis, the findings are grouped according to the research question they address. We find that several names for similar concepts exist, with ecodesign being the most popular one. It has evolved from “end-of-pipe” pollution prevention to a more systemic concept, and addresses the complete life cycle. Barriers and success factors extend beyond the product development team to management, customers, policymakers, and educators. The number of ecodesign methods and tools available to address them is large, and more reviewing, testing, validation, and categorization of the existing ones is necessary. Synergies between ecodesign and other research disciplines exist in theory, but require implementation and testing in practice.

Creative accounting has its background since early studies in 1975, until the present time. It continues to be a subject of great interest for the companies and interested parties. Thus, the current paper will aim to answer the following proposed research questions: 1. Which are the most used methods for detecting the manipulation of financial statements in the literature? 2. Which are the terms that are most frequently encountered in the literature associated with “creative accounting? 3. Which are the journals that have the highest frequency of articles written on the topic “creative accounting”? 4. Over time, how did research evolve in the field of creative accounting? 5. Which countries are most preoccupied in publishing regarding this topic? To answer the research question 1, the models published in the literature for measuring manipulation techniques through creative accounting were reviewed and analyzed. For the remaining research questions, a bibliometric analysis for the publications in this area was performed. For collecting the sample, articles on this topic were selected from the international Web of Science database. Following this, a bibliometric analysis of the articles was performed, using the VOSviewer program. A total of 4045 publications on creative accounting were identified. Through the bibliometric analysis we have answered research question 2, by identifying the key words that have the closest proximity to creative accounting. To answer the remaining research questions, we identified the journals with the highest frequency of publication and the countries with the highest interest on the topic. It is especially important to evaluate the quality of this many research papers and to obtain valuable information.

Abstract This paper examines several research questions relating to equality and equity in Chinese higher education via an extended literature review, which in turn sheds light on evolving scholarly explorations into this theme. First, in the post-massification era, has the Chinese situation of equality and equity in higher education improved or deteriorated since the late 1990s? Second, what are the core issues with respect to equality and equity in Chinese higher education? Third, how have those core issues evolved or changed over time and what does the evolution indicate and entail? Methodologically, this paper uses a bibliometric analysis to detect the topical hotspots in scholarly literature and their changes over time. The study then investigates each of those topical terrains against their temporal contexts in order to gain insights into the core issues.

The general purpose of this study was to examine counseling services as a correlate of institutional commitment and related variables over time on a sample of non-urgent undergraduates. Data for non-urgent clients at a University Counseling Center (UCC) were collected using on-line surveys over four time-periods. Within-time correlations generally showed that mental health concerns was negatively related to institutional commitment, while counseling help belief was positively related. Institutional commitment is defined as a student feeling that he or she selected the right institution to attend Using a smaller sample, i.e., n = 15, of complete-data clients matched-over-time, overall level of mental health concerns significantly declined, while institutional commitment significantly increased. Counseling help belief decreased from Time 1 to Time 2 but then increased over time. Scientifically demonstrating to higher-level University administration that counseling over time can positively influence undergraduates’ institutional commitment can help the UCC to increase its allocation of university-based resources to keep pace with non-urgent client demands.

This study was designed to test the tumor necrosis factor (TNF) WEHI 164 clone 13 bioassay and the interleukin 6 (IL-6) B9 bioassay for sensitivity to endogenously produced dog TNF and IL-6 and then to use these assays to examine the associations between these cytokines and lipopolysaccharide (LPS)-induced fever. When dogs were injected with LPS (40, 10, 1, 0.1, and 0.01 microgram/kg), the resulting fever was dose dependent. A plot of plasma cytokine changes over time following LPS injections showed that the plasma TNF-like activity appeared to increase in an all-or-none dose response, whereas the increase in plasma IL-6-like activity appeared to be log dose dependent. Plasma TNF-like and IL-6-like activity were then separately plotted against temperature change (fever). Statistical analysis supported the interpretation that both TNF-like and IL-6-like activity were related to LPS-fever in an all-or-none manner, with IL-6 having a threshold region. We conclude that if these cytokines are circulating mediators of fever, they may induce fever in an all-or-none fashion.

Objective – The aim of this article is to present evidence based methods for the selection of chemistry monographs, particularly for librarians lacking a background in chemistry. These methods will be described in detail, their practical application illustrated, and their efficacy tested by analyzing circulation data. Methods – Two hundred and ninety-five chemistry monographs were selected between 2005 and 2007 using rigorously-applied evidence based methods involving the Library's integrated library system (ILS), Google, and SciFinder Scholar. The average circulation rate of this group of monographs was compared to the average circulation rate of 254 chemistry monographs selected between 2002 and 2004 when the methods were not used or were in an incomplete state of development. Results – Circulations/month were on average 9% greater in the cohort of monographs selected with the rigorously-applied evidence based methods. Further statistical analysis, however, finds that this result can not be attributed to the different application of these methods. Conclusion – The methods discussed in this article appear to provide an evidence base for the selection of chemistry monographs, but their application does not change circulation rates in a statistically significant way. Further research is needed to determine if this lack of statistical significance is real or a product of the organic development and application of these methods over time, making definitive comparisons difficult.

Este artículo analiza la evolución de la investigación sobre pensamiento histórico a partir de las tesis doctorales nacionales e internacionales de los últimos veinticinco años. Para ello, se ha seguido un proceso sistemático de búsqueda en las principales bases de datos a nivel mundial, que ha reportado un total de 163 tesis doctorales. Estos trabajos se han analizado desde un enfoque metodológico cuantitativo descriptivo, con el programa de análisis estadístico SPSS y la herramienta Voyant Tools. Los resultados nos ofrecen información acerca del número de investigaciones realizadas, su evolución en el tiempo, los países, idiomas y universidades de mayor producción, y las principales temáticas trabajadas. Concluimos que, pese al aumento de las tesis doctorales sobre pensamiento histórico en los últimos años, continúan existiendo vacíos en la investigación apenas abordados. In this article the evolution of research on Historical Thinking is analyzed based on national and international dissertations defended in the last twenty-five years. For this, we have followed a systematic search process in the main databases worldwide, which has reported a total of 163 dissertations. These works have been analyzed from a descriptive quantitative methodological approach, with the SPSS statistical analysis program and the Voyant Tools tool. The results offer us information about the number of researches carried out, their evolution over time, the countries, languages and universities with the highest production, and the main topics studied. We conclude that, despite the increase in doctoral thesis on Historical Thinking in recent years, there are still research gaps that have hardly been studied.

Objectives: This study aims to know the effect of change in culture and technology on efficiency in Dairy Factory - Sudan, 2019-2020 and to know the views of managers on the impact of change management on efficiency, to identify the positive aspects that help in improving this efficiency as well as to identify the negatives Which limit the company's efficiency in this field, by answering the following research questions: - Is there an impact of changing culture and technology on increasing the efficiency of institutions? To answer these questions on which the problem is centered around, the following scientific hypotheses were put forward: - There is a statistically significant relationship between changing the organization's culture and increasing the efficiency of organizations, as well as the existence of a statistically significant relationship between changing technology in the organization and increasing the efficiency of organizations. Methods: The descriptive and analytical approach was used to describe the phenomenon under study, and the questionnaire was used to collect various data. The questionnaire was distributed to the sample members who numbered (55) employees to conduct the statistical analysis for this study, through the program used for the statistical analysis of social sciences, the hypotheses were tested by Median and chi-square. Finding: inflating the culture of the departments and divisions of the company, the stagnation and inflexibility of the society's culture, and the inadequacy of that culture to the requirements of work within the community, which led to an overlap in the powers and responsibilities? The most important recommendations: The necessity of changing the organizational structure to comply with the requirements of work, after carefully studying the internal and external environment, and for the change to take place based on the recommendations of specialists in administrative sciences. So that it is not random and does not lead to an inflation of the organizational structure without success. Value: The importance of the study stems from the fact that it addresses an important topic in business administration, which is managing change in organizations, which is the only way for these organizations to develop and continue to exist. It also studies the reality of change management in the DAL Dairy Factory - Sudan.

<p>Land use in the nearby of a Municipal Solid Waste (MSW) landfill can be strongly affected by the waste management tasks (transport, landfilling and closure). Effects extend from the phases prior to the construction of the landfill until years after the completion of the landfilling process in areas located beyond the perimeter of the plot occupied by the landfill. In this work a new methodology for the analysis of land use change over time is presented. The methodology is based on the use of a new environmental index named WEI (Weighted Environmental Index). WEI is based on the use of GIS techniques accounting for different information sources (digital cartography, aerial photographs and satellite images). WEI assigns environmental values to land use based on the degree of anthropogenic intervention and its occupation surface. A georeferenced multitemporal statistical analysis is performed considering the values of WEI previously assigned to every land use. The methodology has been applied to analyze the land use change near the main MSW landfills of Valencia Region (Spain) where landfilling is currently the only waste disposal technique available. Data have been obtained from the Spanish Land Occupation Information System (SIOSE) public database and integrate GIS information about land use/land cover on an extensive, high-detailed scale. Results demonstrate the application of the WEI to real case studies and the importance of integrating statistical analysis of WEI evolution over time to arrive at a better understanding of the socio-economic and environmental processes that induce land-use change.</p>

Abstract We examined the effects of different types of specimen labels and tags on pH of different concentrations of ethanol typically used for fluid preservation in natural history collections. Labels were immersed in three different concentrations of ethanol, 96% pure undenatured ethanol (EtOH), 96% EtOH denatured with methyl-ethyl ketone (MEK), and 99.8% pure undenatured EtOH, with or without the presence of insect specimens, and the solutions were evaluated after 26 months for changes over time in pH reading. In general, pH readings of all label trials with 96% and 99.8% ethanol increased over time, except for trials of denatured alcohol, which demonstrated lower pH readings in almost all treatments, regardless of label type. Samples that contained labels with ordinary, nonstandardized, not explicitly acid-free printing paper had higher pH readings compared after the trial. Our observations are a good starting point for further experiments to answer research questions related to chemical interactions with labels in ethanol-preserved specimens, including tissue samples for molecular analyses, which can guide collection staff in their daily work.
