description: This study investigates the acquisition of conventional metaphorical expressions by Chinese learners of English. A conventional metaphorical expression, following the definition of cognitive semantics, refers to the use of a conventionalised non-literal meaning of a lexical item in a multi-word phrase. For example, the word ‘attack’ in the phrase ‘attack one’s idea’, which should be interpreted as ‘to criticise somebody or something severely’, clearly departs from the literal meaning ‘to use violence to try to hurt or kill somebody’, and thus should be seen as a metaphorically used word. Consequently, the phrase ‘attack one’s idea’ is a conventional metaphorical expression. This study explores learners’ behaviour towards and acquisition of metaphorical expressions from two major perspectives: (1) possible cross-linguistic influence in the process of acquisition and factors that could affect cross-linguistic influence; and (2) the organisation of learners’ bilingual lexicon and the status of metaphorical expressions in a bilingual lexicon. These two perspectives are considered to be the main factors that can influence learners’ acquisition of metaphorical expressions: in order to acquire a metaphorical expression, learners should be able to integrate it into the bilingual lexicon, while the process of integration can be impacted by cross-linguistic influence. Previous research has mainly been conducted on the acquisition of certain figurative expressions in a second language, predominantly idioms; however, a combination of the two perspectives and a joint analysis on the acquisition of figurative language has yet to be accomplished. This study presents a first attempt of such analysis on the acquisition of a specific type of figurative language. The results of the experiments reported in this dissertation show that learners react differently to metaphorical expressions with different cross-linguistic availabilities (shared between Chinese and English or exclusively available in Chinese or English) but in general they encounter difficulty to achieve native-like performance when reading metaphorical expressions available in their second language. Persistent cross-linguistic influence is observed in two aspects, even among highly proficient learners: (1) learners encounter obstacles when acquiring the metaphorical expressions that are only available in their second language; and (2) learners seem to still activate the metaphorical meanings that are only available in their first language even when they read in their second language. These results altogether reflect that metaphorical expressions, regardless of cross-linguistic availability, are more difficult to acquire than literal expressions in a second language.

description: We calculate the mean evolution of the iron-peak abundance ratios [(Cr,Mn,Co,Zn)/Fe] in the Galaxy, using modern supernova and hypernova chemical yields and a Galactic Chemical Evolution code that assumes homogeneous chemical evolution. We investigate a range of hypernova occurrence rates and are able to produce a chemical composition that is a reasonable fit to the observed values in metal-poor stars. This requires a hypernova occurence rate that is large (50%) in the early Universe, decreasing throughout evolution to a value that is within present day observational constraints (>~ 1%). A large hypernova occurence rate is beneficial to matching the high [Zn/Fe] observed in the most metal-poor stars, although including hypernovae with progenitor mass >= 60 solar masses is detrimental to matching the observed [(Mn,Co)/Fe] evolution at low [Fe/H]. A significant contribution from HNe seems to be critical for producing supersolar [(Co,Zn)/Fe] at low metallicity, though more work will need to be done in order to match the most extreme values. We also emphasise the need to update models for the enrichment sources at higher metallicity, as the satisfactory recovery of the solar values of [(Cr,Mn,Co,Zn)/Fe] still presents a challenge.

description: This review focuses on pesticides, their unquantifiable benefits to agriculture, pesticide residue, maximum pesticide residue limit, and withholding period in grain storage. It delved into the origin of synthetic pesticide and its introduction to Nigeria in the 1950s, it maintained that pesticide have posed major health and social challenges, and have had negative, unintended, catastrophic, fatal consequences to man, animals, and even the environment especially when instructions on their labels are not adhered to. Again, it maintained that withholding periods are often stipulated on the labels of genuine pesticides, it reiterated that not adhering to the stipulated withholding period can have catastrophic consequences on consumers of grain and grain products. Furthermore, it dwelt on the activities of Nigerian stored Products Research Institute (NSPRI) and National Food Drug Administration and Control (NAFDAC), their mandates and quest to nip pesticide poisoning in the bud. Finally, recommendations were put forward to check the seeming ignorance and dearth of information about pesticide residue limit and withholding period, and dangers that are concomitants of not adhering to these.

description: A recently discovered high-Tc cuprate superconductor Ba2CuO$_{4-δ}$ exhibits exceptional Jahn-Teller distortion, wherein the CuO6 octahedrons are compressed along the c axis. As a consequence, the O vacancies prefer to reside in the CuO2 plane, but the exact structure is not known. By combining first-principles total energy calculation with the automated structure inversion method, the effective cluster interactions of O vacancies are mapped out. Around $δ$=0.8, where the 73K superconductivity was observed experimentally, we predict that the ordered O vacancies slice the CuO2 plane into not only 1D chains and but also two-leg ladders. A Monte Carlo simulation is performed based on the effective cluster interaction model, showing that such an ordering pattern is stable up to ~900 K. Our results put forth a concrete structural basis to discuss the underlying superconducting mechanism.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The study was conducted in Fogera district, South Gondar zone, Amhar National Regional State. Three Kebeles among the 15 Kebeles of upland rice growers of the district were selected purposively and a total of 60 selected households were interviewed to generate primary data. Preference ranking technique was employed to identify farmers’ improved upland rice varieties evaluation criteria. The result of the preference ranking shows that market demand, grain yield, taste, drought resistance, and early maturity are the five most important traits required to adopt improved upland rice variety in the study area. Therefore, attempts to promote transformation in agriculture through improved upland rice variety could be successful if these evaluation criteria are taken in consideration.

description: This article empirically analyzes supply-side and demand-side factors expected to affect innovation in clean coal technologies. Patent data from 93
national and international patent offices is used to construct new firm-level
panel data on 3,648 clean coal innovators over the time period 1978 to 2009.
The results indicate that on the supply-side a firm’s history in clean coal
patenting and overall propensity to patent positively a↵ects clean coal innovation. On the demand-side we find strong evidence that environmental
regulation of emissions, that is, CO2, NOX and SO2, induces innovation in
both efficiency improving combustion and after pollution control technologies.

A
Monte Carlo comparison of the HDR bands with existing alternatives shows
that the former are competitive with the bootstrap-based Bonferroni and
Wald confidence regions. The relative tightness of the HDR bands matched
with their good coverage properties makes them attractive for applications.

description: Promoting environmentally friendly farming products is crucial to meeting consumer demand. Although governments implement policy measures to improve the environmental performance of the agriculture sector, their impacts are difficult to assess. This study analyses the performance of agri‐environmental policies in Japan, by using the OECD’s policy impact model and reference level framework. In particular, it identifies the environmental impacts of three simulated agri‐environmental policies based on farms’ characteristics. The results suggest that a policy mix of regulation and an incentive payment would reduce environmental impacts, suggesting that targeted approaches could improve the cost‐effectiveness of agri‐environmental policies.

description: We study the electrostatic potential of a molecular wire bridging two metallic electrodes in the limit of weak contacts. With the use of a tight-binding model including a fully three-dimensional treatment of the electrostatics of the molecular junction, the potential is shown to be poorly screened, dropping mostly along the entire molecule. In addition, we observe pronounced Friedel oscillations that can be related to the breaking of electron-hole symmetry. Our results are in semi-quantitative agreement with recent state-of-the-art ab initio calculations and point to the need of a three-dimensional treatment to properly capture the behavior of the electrostatic potential. Based on these results, current-voltage curves are calculated within the Landauer formalism. It is shown that Coulomb interaction partially compensates the localization of the charges induced by the electric field and consequently tends to suppress zones of negative differential resistance.

description: Economic efficiency is a key issue in economic research and for policy design, and certainly for food security challenges. In the food system dynamics the understanding of changes and trends is crucial to improve our capacity to deal with the objectives of sustainable development and quality of life. Food system efficiency evaluation is necessary with regard to production and consumption efficiencies as well as market and governance dilemmas. Regulations and institutional efficiency are crucial aspects that are frequently forgotten, and efforts should be made to improve the capacity to deal with those methodological needs. In many situations, in the real world, data and measurements are difficult or even impossible to get in numeric or quantitative terms. Frequently, a qualitative evaluation is the only way to proceed, but measurements and numeric references are still important, mainly when changes over time are central to the research. The actual paper follows a structural food system model (WFSE – World Food Security Equation) and a general equilibrium approach (ICI model – induced changes and innovation model) to show in a country case study (Cape Verde) the important role of markets and institutions as compared to regulation practices directed to improve economic efficiency subject to demand behavior. Cape Verde is a very challenging country with regard to the food security status (where natural resources are very poor for agricultural production) but with great success in global and macro terms in the last 10 years. The main problems nowadays are clearly at local level. The present research tries to highlight the global achievements and explore local assessment efforts on food consumption conditions. A specific region is studied, in the island of Santo Antão, one of the most important production regions. Three different production systems were compared mainly with regard to their respective influence on consumption habits, incomes and global interaction and behavior. The results show that food consumption at local level is reasonable good in terms of food security, but that food habits have a determining and surprising influence. Solutions for “food security” improvements are complex and very dependent on social systems, somehow in line with the problems in industrialized economies.

description: While globally optimal solutions to many convex programs can be computed efficiently in polynomial time, this is, in general, not possible for nonconvex optimization problems. Therefore, locally optimal approaches or other efficient suboptimal heuristics are usually applied for practical implementations. However, there is also a strong interest in computing globally optimal solutions of nonconvex problems in offline simulations in order to benchmark the faster suboptimal algorithms. Global solutions often rely on monotonicity properties. A common approach is to reformulate problems into a canonical monotonic optimization problem where the monotonicity becomes evident, but this often comes at the cost of nested optimizations, increased numbers of variables, and/or slow convergence. The framework of mixed monotonic programming (MMP) proposed in this paper avoids such performance-deteriorating reformulations by revealing hidden monotonicity properties directly in the original problem formulation. By means of a wide range of application examples from the area of signal processing for communications (including energy efficiency for green communications, resource allocation in interference networks, scheduling for fairness and quality of service, as well as beamformer design in multiantenna systems), we demonstrate that the novel MMP approach leads to tremendous complexity reductions compared to state-of-the-art methods for global optimization. However, the framework is not limited to optimizing communication systems, and we expect that similar speed-ups can be obtained for optimization problems from other areas of research as well.

description: The characterization of quantum correlations is crucial to the development of new quantum technologies and to understand how dramatically quantum theory departs from classical physics. Here we systematically study single- and multiparticle interference patterns produced by general two- and three-qubit systems. From this we establish on phenomenological grounds a new type of quantum correlation for these systems, which we name quantum interference, deriving some quantifiers that are given explicitly in terms of the density matrix elements of the complete system. By using these quantifiers, we show that, contrary to our expectations, entanglement is not a required property for a composite quantum system to manifest multiparticle interference.

description: The traditional heat-load generation pattern of combined heat and power generators has become a problem leading to renewable energy source (RES) power curtailment in cold regions, motivating the proposal of a planning model for alternative heat sources. The model aims to identify non-dominant capacity allocation schemes for heat pumps, thermal energy storage, electric boilers, and combined storage heaters to construct a Pareto front, considering both economic and sustainable objectives. The integration of various heat sources from both generation and consumption sides enhances flexibility in utilization. The study introduces a novel optimization algorithm, the adaptive multi-objective Bayesian optimization (AMBO). Compared to other widely used multi-objective optimization algorithms, AMBO eliminates predefined parameters that may introduce subjectivity from planners. Beyond the algorithm, the proposed model incorporates a noise term to account for inevitable simulation deviations, enabling the identification of better-performing planning results that meet the unique requirements of cold regions. What's more, the characteristics of electric-thermal coupling scenarios are captured and reflected in the operation simulation model to make sure the simulation is close to reality. Numerical simulation verifies the superiority of the proposed approach in generating a more diverse and evenly distributed Pareto front in a sample-efficient manner, providing comprehensive and objective planning choices.

description: We provide an empirical study analysing the distribution of EU funds among 2478 Polish municipalities in the period of the multiannual financial framework 2007 – 2013. We find EU funds to be concentrated in smaller municipalities and economically weak sub-regions. Expenditures of EU funds per capita do not decrease in the municipalities’ fiscal capacity. This indicates that co-funding restrictions imposed by the EU did not prevent fiscally weak municipalities from attracting EU funds. Our primary focus rests on the question whether regional governments use their prominent role in the allocation process for EU funds to support their own political self-interest. Difference-in-difference estimations show that the answer is affirmative: Municipalities aligned with the regional government spend more EU funds per capita than nonaligned municipalities. Furthermore, we find support for the swing-district hypothesis: EU funds per capita decrease in the vote-share differential between the two leading parties.

description: Like most of the benthos, brachiopods suffered huge losses in biodiversity during the end-Permian extinction and did not fully recover until the Anisian (Middle Triassic). Anisian brachiopod faunas are thus a key clade characterizing the recovered marine ecosystems in the early Mesozoic. Of these, the brachiopod fauna from Qingyan Town in Guizhou Province, south-western China has long been one of the best-known Anisian faunas in the world. The taxonomy of the Qingyan fauna, however, was last studied half a century ago, and thus requires revision. Here we describe 34 species (and subspecies) (including seven undetermined species) assigned to 29 brachiopod genera from the Qingyan Formation from the Leidapo and Wachangpo localities in the Qingyan section. Of these, 11 species are described for the first time from this area. Two new genera: Parabrekia and Caucasorhynchella (= Crurirhynchella Xu & Liu, 1983, a nomen nudum) and seven new species (Angustothyris dagysi, Angustothyris qingyanensis, Koeveskallina bifurcata, Neocyrtina xui, Nudirostralina minuta, Parabrekia yangi and Rutorhynchia? trigonalis) are also erected. The Qingyan brachiopod fauna is characterized by abundant endemic genera (33.3%) and exhibits a weak similarity with several coeval faunas reported from the western Tethys. In addition, faunal affinity analyses of 13 Anisian brachiopod faunas indicate that at least five biogeographical provinces (western Tethys, eastern Tethys, northern Siberia, Himalayas and New Zealand) were present during the Anisian, and the eastern Tethys province included three subprovinces: Yangtze, southern Qilian–western Qinling and central Qinghai. However, most faunas mutually share rather low Jaccard similarity coefficients (<0.4), except for those in the western Tethys, implying a continuity of the multi-provincial pattern established for Early Triassic brachiopod distributions. http://zoobank.org/urn:lsid:zoobank.org:pub:AAD98089-C804-4AF4-BC73-CDA5823C66A7

description: The food sector in Europe can be characterized as a complex, global and dynamically changing network of trade streams, food supply network relations and related product flows which offers a big spectrum for economic output and employment. Innovation is important for the competitiveness of the food industry that is to a large extent comprised of small and medium sized enterprises (SMEs). For them, innovation has grown extremely subordinate to interaction in networks. Network initiatives that could provide appropriate support involve social interaction and knowledge exchange, learning and competence development, and coordination (organization) and management of implementation. This paper is designed to assess the factors that affect the performance of German food SME formal networks. It also addresses the consequences at the network and macro level. The analysis was explored by using the laddering technique based on the means‐end chain theory. The findings will help to build up a “network learning toolbox” that is adapted to the particular requirements of the different target groups such as of SMEs, network managers and policy makers. The “network learning toolbox” should improve network learning, which is a driver for improvements in innovation, economic growth and sustainable competitive advantage for food SMEs.
The FIR/Radio correlation of high redshift galaxies in the HDF-N

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: The correlation between the far-infrared (FIR) and radio emission is well established for nearby star forming galaxies. Many applications, in particular the radio-to-submm spectral index redshift indicator, tacitly assume that the relation holds well beyond our local neighbourhood, to systems located at cosmological distances. In order to test this assumption I have constructed a sample of 20 HDF-N galaxies, all with measured spectroscopic redshifts, and all detected by both ISO and the WSRT at 15 micron and 1.4 GHz respectively. The galaxies span a wide range of redshift with a median value of z ~ 0.7. The ISO 15 micron data were k-corrected and extrapolated to the FIR (60 and 100 micron) by assuming a starburst (M82) spectral energy distribution (SED) for the entire sample. An initial analysis of the data suggests that the correlation between the FIR and the radio emission continues to apply at high redshift with no obvious indication that it fails to apply beyond z ~ 1.3. The sample is ``contaminated'' by at least 1 distant (z=4.4), radio-loud AGN, VLA J123642+621331. This source has recently been detected by the first deep field VLBI observations of the HDF-N and is clearly identified as an outlier in the FIR/radio correlation.

description: In this paper, we examine the relationship between market participants’ perception of central bank predictability and their assessment of central bank communication skills and success in conveying objectives as well as the importance of transparencyenhancing measures, such as voting records, transcripts or minutes of policy meetings, and conditional interest rate projections. Our analysis is based on a unique dataset of almost 500 market participants worldwide who were asked questions with respect to the performance of the Bank of England, the Bank of Japan, the European Central Bank, and the Federal Reserve. Our results indicate a positive and economically notable relationship between central banks’ ability to convey their objectives and their overall communication skills on the one hand, and market participants’ perception of the banks’ predictability on the other hand, for all four central banks. The dissemination of more specific information does not appear to contribute to better central bank predictability. This raises doubts about the widely-held notion that implementing ever more transparency-enhancing measures will improve central bank predictability.

description: Selecting the best structure and parameterization of rainfall–runoff models is not straightforward and depends on a broad number of factors. In this study, the “Modello Idrologico Semi-Distribuito in continuo” (MISDc) was tested on 63 mountainous catchments in the western Po Valley (Italy) and the optimal model parameters were regionalized using different strategies. The model performance was evaluated through several indexes analysing hydrological regime, high-flow condition and flow–duration curve (FDC). In general, MISDc provides a good fit behaviour with a Kling-Gupta Efficiency index greater than 0.5 for 100% and 84% of cases for calibration and validation, respectively. Concerning the regionalization, spatial proximity approach is the most accurate solution obtaining satisfactory performance. Lastly, the predicted FDCs showed an excellent similarity with the observed ones. Results encourage to apply MISDc over the study area for flood forecasting and for assessing water resources availability thanks to the modest computational efforts and data requirements.

description: We study a setting in which one or two agents conduct research on
behalf of a principal. The agents' success depends on effort and the
choice of a research technology that is uncertain with respect to its
quality. A single agent has no incentive to deviate from the principal's
preferred technology choice. In the multiagent-setting researchers pursue
individual rather than overall success which yields a preference for
the most promising technology. We show that a mechanism that deters
this bias towards mainstream research always entails an effciency
loss if researchers are risk-averse. Our results suggest that there is too
little diversity in delegated research.

description: In the past few decades, the market for organic food has developed well in Western European countries and comparable markets like the United States or Canada. While these markets are now approaching market saturation, other markets still have huge potential for growth and are therefore of special interest to export companies. In this paper, we analyze the demands, knowledge, and expectations of the emerging market in Russia. It is well documented that the Russian market for organic food has had a much higher growth rate than Western markets in recent years. According to the USDA, the Russian market grew significantly during the last years. The increase might also be due to changes in Russian consumers’ behavior. However, some challenges must be considered when entering the Russian market with premium products: (1) a large number of low‐income consumers are not able to pay for premium products, and (2) up until now, there have been no official organic labels available in Russia, and, therefore, it is likely that the Russian population lacks knowledge of what organic food is and which requirements are connected to the organic production process. Considering these restrictions, we analyzed important factors affecting Russian consumers’ food choice on the one hand and their knowledge of organic food on the other. This paper presents results for one specific product (organic potatoes), which can be considered to be a typical alternative to low‐priced, conventional products. A conjoint analysis was conducted in Saint Petersburg (n = 300) to investigate the importance of the buying attributes of organic potatoes. While the results are not representative of the whole Russian market, they show crucial differences in consumer attitudes compared to Western markets and confirm that the average consumer knowledge about this product category remains low. These findings offer valuable information to those stakeholders of the supply chain who want to enter a market with high growth rates but obvious shortcomings.

description: Directional point-contact spectroscopy measurements were performed for the first time in state-of-the-art MgB_2 single crystals. The selective suppression of the superconductivity in the "pi" band by means of a suitable magnetic field allowed separating the partial contribution of each band to the total point-contact conductance. By fitting the partial conductance curves sigma_sigma(V) and sigma_pi(V), we got an independent determination of the two gaps, Delta_sigma and Delta_pi, with a strong reduction of the experimental uncertainty. Their temperature dependence was found to agree well with the predictions of the two-band models for MgB_2.

description: The current paper aims to outline the potential and most important aspects of the Strategic Environmental Assessment process (directive 2001/42/EC). First of all, the analysis considers the importance of evaluation instruments in decision-making processes and moves on to environmental assessment, focusing on the peculiarities of Strategic Environmental Assessment. Although SEA is an innovative instrument in favouring and promoting a democratic approach to the government and development of the territory, it nonetheless presents a series of problems. The latter regard aspects such as: its integration into planning and programming activities, its role within these processes, the methodologies applied, stakeholder involvement, the quality of the assessment process and the how the suggestions are perceived and acknowledged.

description: We analyze survey data on the proposal to introduce a tax exemption for caregiving heirs to the German inheritance tax. Some 80 percent of the participants support this exemption, about half of those supporting the tax exemption want to see it restricted to relatives. We explain interpersonal differences in policy preferences using a wide range of personal characteristics, beliefs and attitudes. Neither subjects’ sex, nor their valuation of the family is found to have an effect while personal experience in long- term care provision and having alive parents strongly shape policy preferences. Subjects with alive parents and/or personal experience in long-term care provision are more likely to support the tax exemption but less likely to support the restriction to relatives. This result supports the bottom line of the recent social science literature on home care provision and intergenerational relations within the family: Many citizens in Germany feel overburdened with caregiving.

description: This paper aims to analyse, at a European level, the extent to which dispositions contained in Council Directive 91/676/CEE have been applied. The Directive aims to decrease water pollution directly or indirectly caused by nitrates from agricultural sources, and to prevent other similar pollution. The analysis considers the main pressure factors within the Member States, the state of their implementation at a European level and also puts forward suggestions which bear in mind the fact that Europe cannot give up its agricultural sector and that water is a limited resource which is necessary for human survival.
Particle tunneling through a polarizable insulator

description: The tunneling probability between two leads connected by a molecule, a chain, a film, or a bulk polarizable insulator is investigated within a model of an electron tunneling from lead A to a state higher in energy, describing the barrier, and from there to lead B. To describe the possibility of energy exchange with excitations of the molecule or the insulator we couple the intermediate state to a single oscillator or to a spectrum of these, respectively. In the single-oscillator case we find for weak coupling that the tunneling is weakly suppressed by a Debye-Waller-type factor. For stronger coupling the oscillator gets 'stiff' and we observe a suppression of tunneling since the effective barrier is increased. The probability for the electron to excite the oscillator increases with the coupling. In the case of a film, or a bulk barrier the behavior is qualitatively the same as in the single oscillator case. An insulating chain, as opposed to a film or a bulk connecting the two leads,shows an 'orthogonality catastrophe' similar to that of an electronic transition in a Fermi gas.

description: The economic impact of data breaches is a serious problem for retailers. It may be difficult for SMEs to predict the impact of data breaches on brand perception and calculate the impact on stock prices, but they should not underestimate the dull financial cost of a cyber-attack as one of the risks of e-commerce. E-commerce today is one of the fastest growing sectors in the world, adding 6 million new members each month with the support of a growing Internet user base. The e-commerce industry in its current form is a complex ecosystem. It includes large volumes of transactions, reliance on newer technologies such as mobile payment wallets and mobile applications for customer access, and reliance on third-party vendors for product purchasing and logistics. The purpose of the article is to explore and analyze the main typologies of risks associated with e-commerce. When the problem is simply the ordering of unconditional phenomena, it is difficult to distinguish typologies from classifications. The latter were considered preliminary to the discovery of sequences or laws. Because typologies invariably use ordering for additional purposes, classifications can be considered as typologies that are limited to the problem of order. Typologies that typically exist at the frontiers of research are less durable than classifications because their descriptions are accepted only insofar as they continue to provide solutions to problems. The application of the typology method has a number of clear advantages for research and measurement, and is in fact a central feature of these efforts. Typology is the main descriptive tool.
