Abstract This paper aims at presenting some thoughts on the hypothesis of an Anatolian-Greek language area in the second millennium bc comparing different approaches both in the theoretical frames and in the analysis of the linguistic facts. For this purpose, it is necessary to introduce some terminological premises, followed by a selection of methodological issues, which will help explore the putative features that characterize the Anatolian-Greek area (morphological traits such as actionality markers, particles, verbal prefixes as well as special morphological forms; morphosyntactic traits, such as modal particles, sentence particles, absolute participial constructions; lexical units and phonetic features).

The identification of traits associated with drought tolerance in popcorn is a contribution to support selection of superior plants under soil water deficit. The objective of this study was to choose morphological traits and the leaf greenness index, measured on different dates, to estimate grain yield (GY) and popping expansion (PE), evaluated in a set of 20 popcorn lines with different genealogies, estimated by multiple regression models. The variables were divided into three groups: morpho-agronomic traits—100-grain weight (GW), prolificacy (PR), tassel length (TL), number of tassel branches, anthesis-silking interval, leaf angle (FA) and leaf rolling (FB); variables related to the intensity of leaf greenness during the grain-filling period, at the leaf level, measured by a portable chlorophyll meter (SPAD) and at the canopy level, calculated as the normalized difference vegetation index (NDVI). The inbred lines were cultivated under two water conditions: well-watered (WW), maintained at field capacity, and water stress (WS), for which irrigation was stopped before male flowering. The traits GY (55%) and PE (28%) were most affected by water restriction. Among the morpho-agronomic traits, GW and PR were markedly reduced (>10%). Under dry conditions, the FA in relation to the plant stalk tended to be wider, the FB curvature greater and leaf senescence accelerated (>15% at 22 days after male flowering). The use of multiple regression for the selection of predictive traits proved to be a useful tool for the identification of groups of adequate traits to efficiently predict the economically most important features of popcorn (GY and PE). The SPAD index measured 17 days after male flowering proved useful to select indirectly for GY, while, among the morphological traits, TL stood out for the same purpose. Of all traits, PR was most strongly related with PE under WS, indicating its use in breeding programs. The exploitation of these traits by indirect selection is expected to induce increments in GY and PE.

Selection Of

We introduce a method that permits to co-evolve the body and the control properties of robots. It can be used to adapt the morphological traits of robots with a hand-designed morphological bauplan or to evolve the morphological bauplan as well. Our results indicate that robots with co-adapted body and control traits outperform robots with fixed hand-designed morphologies. Interestingly, the advantage is not due to the selection of better morphologies but rather to the mutual scaffolding process that results from the possibility to co-adapt the morphological traits to the control traits and vice versa. Our results also demonstrate that morphological variations do not necessarily have destructive effects on robots’ skills.

The finding in Morehead and Ingram (1973) that children with a language impairment do better in the use of inflectional morphology than MLU-matched typically developing children has been in marked contrast to several subsequent studies that have found the opposite relationship (cf. review in Leonard, 1998). This research note presents a reanalysis of a subset of the original Morehead and Ingram data in an attempt to reconcile these contradictory findings. The reanalysis revealed that the advantage on inflectional morphology for children with language impairment was only on the progressive suffix, not on plural and possessive or on the verbal morphemes third-person present tense and past tense. The results of the reanalysis are in line with more recent research (e.g., Rice, Wexler, & Cleave, 1995). The resolution of these discrepant results highlights the critical roles that methodological issues play—specifically, how subjects are matched on MLU, how inflectional morphology is measured, and the selection of subjects with regard to age.

The present investigation was conducted with 36 genotypes of mungbean on 26 agro-morphological traits including seed yield and pubescence traits to access the degree of divergence for mungbean improvement during <italic>zaid</italic> 2012. These mungbean genotypes were grouped into seven clusters. Cluster IV comprised of 14 genotypes, forming the largest cluster followed by cluster VI comprised eight genotypes, cluster I comprised seven genotypes and cluster II comprised four genotypes. Three clusters <italic>viz.</italic>, cluster III, V & VII formed mono genotypic cluster. All the pubescence traits contributed towards total divergence. Among the agro-morphological traits, high contribution towards total divergence was recorded for beak length, average intermodal length, primary branch angle with main stem, biological yield, seed yield and pods per cluster, indicated the possibility of selection of parent(s) for hybridization to manipulate the targeted trait(s) for mungbean improvement.

The purpose of this paper is to discuss important methodological issues that must be considered in planning and implementing clinical evaluation research in occupational therapy. The experiences of the authors in conducting a multi-centre intervention trial are used to illustrate issues and decisions which can both enhance the scientific integrity of clinical research while maint a ining its feasibility. Methodological issues include choice of research design, identification of significant confounding variables, subject selection and enrollment, incidence-prevalence bias, selection of appropriate and responsive outcome measures, maintenance of treatment consistency and compliance, and “masked” evaluation of outcomes. Attention to these issues will increase the methodological quality of occupational therapy evaluation research and improve the credibility of its results.

It is important to predict trends of economic development for any country. Researchers and practitioners use different ways for evaluation and forecasting economic activity. Identification of indicators, which change impact on the economy in general, is one of the widespread methods. The most appropriate tools to solve this problem are the leading indicators and indexes based on leading indicators. The selection of indicators depends on the specificity of the country’s economy. Among the leading economic indicators is the dynamics of applications for the Building permissions for private houses, and can also be successfully use residential transactions. Depending on the above, the paper deals the aspects of calculation of leading economic indicators. This paper analyses some aspects of the effectiveness of indicator for predicting economic activity and describes the methodological issues forward leading indicators. Particular attention is paid to analysis of residential transactions dynamics as a leading indicator as in theoretical as in practical terms. The article highlights the peculiarities of its implementation in Georgia.

In the absence of random treatment assignment, the selection of appropriate control variables is essential to designing well-specified empirical tests of causal effects. However, the importance of control variables seems underappreciated in accounting research relative to other methodological issues. Despite the frequent reliance on control variables, the accounting literature has limited guidance on how to select them. We evaluate the evolution in use of control variables in accounting research and discuss some of the issues that researchers should consider when choosing control variables. Using simulations, we illustrate that more control is not always better and that some control variables can introduce bias into an otherwise well-specified model. We also demonstrate other issues with control variables including the effects of measurement error and complications associated with fixed effects. Lastly, we provide practical suggestions for future accounting research.
