An exploration of the applicability and usefulness of complexity theory to community development
Creators: name: Plecke, Joanna
Publisher: name: University of British Columbia
Year: 2009

description: Complexity theory studies the workings of complex adaptive systems (CAS). A complex adaptive system can adapt and change in response to information it gathers from its environment. It responds to feedback by changing its actions, and develops new activities, learning capacity and ability to innovate. Complex adaptive systems depend on information flow through linked networks of individuals and groups, such as those present in cities or communities. Hornby Island, a small northern gulf island in British Columbia, Canada, possesses the characteristics of a complex adaptive system and is used to provide examples of how complexity theory can be applied and used by a community. Observations from Hornby Island and the use of SWOT analysis (strengths, weaknesses, opportunities and threats) have provided insight to the applicability and usefulness of complexity theory in the theoretical and local action contexts of community development. Misunderstandings between the scientific and humanitarian backgrounds of complexity and community development theories represent weaknesses and pose some threats to the field of community development. However, complexity theory also possesses strengths that have the potential to provide community development practitioners and communities with opportunities, such as tools and ideas, to better adapt to change. The following opportunities for learning and action within communities are suggested and expanded upon in this thesis: human led creative adaptation; location of mal-adaptive schemata; education for adaptive schemata; reducing and changing mal-adaptive schemata; guidelines and generalizations; and intangibles and legitimization of actions. This thesis concludes that complexity theory is applicable and useful to community development because it strengthens other theories and concepts related to community development; helps frame what goes on in the community; and locates focuses for change. It also provides new tools and ideas for action, to communities and practitioners, to better deal with change and create resilient communities.
Discrete Gauge Symmetries, Baryon Number and Large Extra Dimensions

description: Krauss and Wilczek have shown that an unbroken discrete gauge symmetry is respected by gravitationally mediated processes. This has led to a search for such a symmetry compatible with the standard model or MSSM that would protect protons from gravitationally mediated decay in a universe with a low scale for quantum gravity (large extra dimensions). The fact that the discrete symmetry must remain unbroken and have a gauge origin puts important restrictions on the space of possible discrete symmetries.

description: The aim of the present meta-analysis was to find out the impact of MIF -173 G > C polymorphism on risk of tuberculosis (TB). We conducted a search of case–control studies on the associations of -173 G > C variant of MIF with susceptibility to tuberculosis in PubMed, ISI Web of Science, and Scopus. We extracted the data from eligible studies and achieved a meta-analysis to examine the relationship between MIF -173 G > C polymorphism and the risk of TB. Odds ratios (ORs) with the corresponding 95 % confidence intervals (CIs) were pooled to find out the impact of MIF -173G > C promoter polymorphism on TB risk. The pooled ORs were calculated for the codomi- nant, dominant, recessive, and allelic model comparison. The findings revealed that MIF -173 G > C variant increased the risk of TB in codominant (OR = 1.54, 95 %CI = 1.26-1.88, p < 0.0001; CG vs GG), and dominant (OR = 1.62, 95 %CI = 1.33-1.96, p < 0.00001; GC+CC vs GG) inheritance models tested. The results suggested that the MIF -173 C allele significantly increased the risk of PTB (OR = 1.49, 95 %CI = 1.28-1.74, p < 0.00001). The findings of this meta-analysis propose that MIF -173 G > C variant is associated with the risk of TB. More case-control studies with well-designed in different ethnic groups and larger sample size are needed to confirm the findings.

description: Generative adversarial networks (GANs) are a machine learning framework comprising a generative model for sampling from a target distribution and a discriminative model for evaluating the proximity of a sample to the target distribution. GANs exhibit strong performance in imaging or anomaly detection. However, they suffer from training instabilities, and sampling efficiency may be limited by the classical sampling procedure. We introduce variational quantum-classical Wasserstein GANs to address these issues and embed this model in a classical machine learning framework for anomaly detection. Classical Wasserstein GANs improve training stability by using a cost function better suited for gradient descent. Our model replaces the generator of Wasserstein GANs with a hybrid quantum-classical neural net and leaves the classical discriminative model unchanged. This way, high-dimensional classical data only enters the classical model and need not be prepared in a quantum circuit. We demonstrate the effectiveness of this method on a credit card fraud dataset. For this dataset our method shows performance on par with classical methods in terms of the $F_1$ score. We analyze the influence of the circuit ansatz, layer width and depth, neural net architecture parameter initialization strategy, and sampling noise on convergence and performance.

description: Motivated by the physics of mobile triplets in frustrated quantum magnets, the properties of a two dimensional model of bosons with correlated-hopping are investigated. A mean-field analysis reveals the presence of a pairing phase without single particle Bose-Einstein condensation (BEC) at low densities for sufficiently strong correlated-hopping, and of an Ising quantum phase transition towards a BEC phase at larger density. The physical arguments supporting the mean-field results and their implications for bosonic and quantum spin systems are discussed.

description: We study the ultrafast demagnetization of Ni/NiMn and Co/NiMn ferromagnetic/antiferromagnetic bilayer systems after excitation by a laser pulse. We probe the ferromagnetic order of Ni and Co using magnetic circular dichroism in time-resolved pump-probe resonant x-ray reflectivity. Tuning the sample temperature across the antiferromagnetic ordering temperature of the NiMn layer allows us to investigate effects induced by the magnetic order of the latter. The presence of antiferromagnetic order in NiMn speeds up the demagnetization of the ferromagnetic layer, which is attributed to bidirectional laser-induced superdiffusive spin currents between the ferromagnetic and the antiferromagnetic layer.

description: In contrast to Bell's inequalities which test the correlations between multiple spatially separated systems, the Leggett-Garg inequalities test the temporal correlations between measurements of a single system. We experimentally demonstrate the violation of the Leggett-Garg inequality in a classical optical system using only the polarization degree-of-freedom of a laser beam. Our results show maximal violations of the Leggett-Garg inequality.

description: Based upon the known potential interaction between omeprazole (OMP) and clopidogrel (CLOP), the current study was designed to evaluate the effect of CLOP on disposition of OMP and its two major metabolites, 5-hy- droxyomeprazole (5-OH-OMP) and omeprazole sulfone (OMP-S) in healthy clinical subjects. A randomized, open label, 2-period, crossover study was designed. Twelve volunteers were selected, of whom eight were extensive metabolizers (EM) of CYP2C19 and 4 were poor metabolizers (PM). They received single dose of OMP either alone or in combination with CLOP (single dose) and samples were collected periodically to calculate various pharmacokinetic parameters. Changes in most of the pharmacokinetic parameters of OMP, 5-OH-OMP and OMP- S were insignificant (P ˃ 0.05) both in EM and PM except for the maximum concentration (Cmax) of 5-OH-OMP and OMP-S in EM. The OMP Cmax and AUC0-∞ was increased both in EM and PM after concomitant administration of OMP with CLOP. The 5-OH-OMP Cmax was decreased in both EM and PM, demonstrating that CLOP inhibits hydroxylation of OMP. The OMP-S Cmax and AUC0-∞ were increased both in EM and PM showing that CLOP may induce sulfoxidation of OMP. It was concluded that CLOP may inhibit hydroxylation of OMP to a greater extent in EM than in PM, leading to higher OMP Cmax and AUC0-∞. Furthermore, the sulfoxidation of OMP may also be induced by CLOP. So, it is suggested that both these drugs should be carefull prescribed together to avoid any harm to the patients.

description: Για την αποτελεσματική συμπερίληψη των μαθητών με διαφορετικό πολιτισμικό υπόβαθρο στο σχολικό περιβάλλον απαιτείται μια ηγεσία που να ενσωματώνει μέσα της τα χαρακτηριστικά της πολιτισμικής απόκρισης. Στην παρούσα διερευνητική μελέτη εξετάστηκαν οι παράγοντες που παρεμποδίζουν ή διευκολύνουν την εφαρμογή της ηγεσίας της πολιτισμικής απόκρισης στα ελληνικά σχολεία. Στην έρευνα συμμετείχαν 10 διευθυντές της Δευτεροβάθμιας Εκπαίδευσης σχολείων της Αττικής. Ως εργαλείο έρευνας χρησιμοποιήθηκε η ημιδομημένη συνέντευξη. Ως δειγματοληψία χρησιμοποιήθηκε η δειγματοληψία ευκολίας. Για την ανάλυση των ποιοτικών αποτελεσμάτων της ποιοτικής έρευνας χρησιμοποιήθηκε η ανάλυση περιεχομένου με τη δημιουργία κωδίκων και θεματικών κατηγοριών. Τα βασικά συμπεράσματα της έρευνας είναι τα εξής: α) οι διευθυντές των σχολικών μονάδων δείχνουν ενδιαφέρον για την ενσωμάτωση των μεταναστών στο σχολικό περιβάλλον στο πλαίσιο της συμπεριληπτικής εκπαίδευσης, β) οι διευθυντές θεωρούν τη συμπεριληπτική εκπαίδευση σημαντική καθώς βοηθάει: στην μείωση των στερεοτύπων και των προκαταλήψεων, στην προώθηση των δημοκρατικών αξιών, στην δημιουργία ανοικτών σχολικών περιβαλλόντων που αποδέχονται την διαφορετικότητα, δίνοντας ίσες ευκαιρίες μάθησης και μειώνοντας τις συγκρούσεις και στην προώθηση της εκπαίδευσης για την ειρήνη, γ) οι διευθυντές του δείγματος εφαρμόζουν κάποιες πολιτικές της ηγεσίας πολιτισμικής απόκρισης για τη συμπερίληψη των παιδιών των μεταναστών στην σχολική μονάδα (πρακτικές για την ενσωμάτωση των μαθητών με διαφορετικό πολιτισμικό υπόβαθρο, διάδοση των αξιών της διαπολιτισμικότητας στη σχολική μονάδα με τη δημιουργία του κατάλληλου σχολικού κλίματος, εφαρμογή μεθόδων για την αξιολόγηση των εκπαιδευτικών, κ.α.). Τα σημαντικότερα προβλήματα των διευθυντών είναι τα εξής: η ανυπαρξία νομοθεσίας, η έλλειψη επιμόρφωσης εκπαιδευτικών, το ασφυκτικό ωρολόγιο πρόγραμμα, και απουσία μέριμνας από το κράτος. Οι προτάσεις που έκαναν οι διευθυντές με την ολοκλήρωση της έρευνας είναι οι εξής: επιμόρφωση των εκπαιδευτικών, ανταλλαγή καλών πρακτικών με άλλα σχολεία και παροχή βοήθειας από το κράτος με σχετικές νομοθετικές πρωτοβουλίες.

description: Strong-field ionization of dense molecular gases in a short infrared laser pulse is studied by means of photoelectron spectroscopy combined with a liquid microjet technique. By increasing the gas density, we observe how the laser- assisted electron scattering on neighboring particles becomes a dominant mechanism of hot electron emission. The angle-resolved energy distributions of rescattered electrons are obtained by analyzing the density dependency of emission spectra. A semiclassical consideration of electron trajectories is shown to provide a good description of experimental spectra. The model predicts the existence of four energy plateaus. Two cutoffs at higher energies are evident in the spectra.

description: Cosmic superstrings are produced at the end of brane inflation. Their properties are similar to cosmic strings arising in grand unified theories. Like cosmic strings they can give rise to a primordial magnetic field, as a result of vortical motions stirred in the ionised plasma by the gravitational pull of moving string segments. The resulting magnetic field is both strong enough and coherent enough to seed the galactic dynamo and explain the observed magnetic fields of the galaxies.

description: Klebsiella (K.) pneumoniae is a major pathogen in human and veterinary medicine, known for its high resistance rates. Comprehensive resistance data are essential to combat global antibiotic resistance. This study aims to (a) document the prevalence of resistant K. pneumoniae and (b) assess the utility of routine laboratory data for passive monitoring. We analyzed a dataset of 175,171 samples from diseased dogs and cats in Germany collected between 2019 and 2021, identifying 1185 K. pneumoniae isolates with measurable minimum inhibitory concentration values. We evaluated resistance rates to a third-generation cephalosporin (cefovecin) (16.3%), chloramphenicol (16.1%), doxycycline (13.9%), enrofloxacin (8.9%), gentamicin (6.0%), nitrofurantoin (24.8%), and sulfamethoxazole-trimethoprim (15.0%). Notably, feline K. pneumoniae isolates from the urinary tract showed a high cefovecin resistance rate of 70.0%. Comparing our findings with third-generation cephalosporin-resistant human isolates from the Antimicrobial Resistance Surveillance database (ARS) maintained by the Robert Koch Institute revealed a lower resistance rate (7.7%). This study presents Germany’s most comprehensive dataset on K. pneumoniae resistance in companion animals over a three-year period. These findings can strengthen national resistance monitoring efforts and enhance data interpretation through substantial datasets.

description: Although the sphere decoder (SD) is a powerful detector for multiple-input multiple-output (MIMO) systems, it has become computationally prohibitive in massive MIMO systems, where a large number of antennas are employed. To overcome this challenge, we propose fast deep learning (DL)-aided SD (FDL-SD) and fast DL-aided $K$-best SD (KSD, FDL-KSD) algorithms. Therein, the major application of DL is to generate a highly reliable initial candidate to accelerate the search in SD and KSD in conjunction with candidate/layer ordering and early rejection. Compared to existing DL-aided SD schemes, our proposed schemes are more advantageous in both offline training and online application phases. Specifically, unlike existing DL-aided SD schemes, they do not require performing the conventional SD in the training phase. For a $24 \times 24$ MIMO system with QPSK, the proposed FDL-SD achieves a complexity reduction of more than $90\%$ without any performance loss compared to conventional SD schemes. For a $32 \times 32$ MIMO system with QPSK, the proposed FDL-KSD only requires $K = 32$ to attain the performance of the conventional KSD with $K=256$, where $K$ is the number of survival paths in KSD. This implies a dramatic improvement in the performance--complexity tradeoff of the proposed FDL-KSD scheme.

description: Several polyphenol-rich Terminalia species (Combretaceae) are known to accelerate wound healing. Recently, the Omani medicinal plant Anogeissus dhofarica (now Terminalia dhofarica) was attributed to the genus Terminalia based on phylogenetic studies. Leaves, bark, and extracts of T. dhofarica are traditionally used for various medicinal purposes, including wound treatment and personal hygiene. In the present study, the phytochemical profile of leaves from T. dhofarica was evaluated by ultra-high-performance liquid chromatography coupled with electrospray ionization high-resolution mass spectrometry (UHPLC-ESI-HRMS) and nuclear magnetic resonance (NMR) spectroscopy. Simple phenolics, polyphenolics (e.g., flavonoids and tannins) and their glucosides were characterized as major metabolite classes. In addition, 20 phenolics were isolated and structurally identified. Nine of these compounds were never described before for T. dhofarica. For the first time, we provide complete NMR data for 1-O-galloyl-6-O-p-coumaroyl-d-glucose (1). Biological screening demonstrated moderate efficacy against the Gram-negative bacterium Aliivibrio fischeri, the phytopathogenic fungus Septoria tritici, and the oomycete Phytophthora infestans. In summary, the data expand the knowledge of the phytochemistry of the underexplored species T. dhofarica and underscore its potential for therapeutic applications, particularly in the context of traditional medicine.
ANALYSING RUSSIAN FOOD EXPENDITURE USING MICRO-DATA

description: Since the beginning of transition, the level and structure of average food consumption and expenditure of Russian households has changed substantially. This development has gone together with a steep increase in the share of food in total expenditure. Notable differences with respect to food expenditure are observed between distinct household strata. In this paper, food demand of Russian households is investigated. For this purpose, households are classified by sociodemographic characteristics, and differences between food demand patterns of various household types are described using data of a Russian household survey of 1996. Russian food demand is econometrically estimated for seventeen food commodities belonging to five groups using a two-stage linear approximation of the Almost Ideal Demand System (LA/AIDS). Total expenditure allocation on food and non-food is analysed using Working's Engel model. The basic models are extended by sociodemographic factors. In a first step, unit values of food commodities are adjusted for quality differences and Probit analyses are carried out to analyse the decision to purchase food commodities. In a second step, the Engel model and the LA/AIDS are estimated applying the Generalised Heckman procedure in order to account for estimation bias introduced from zero expenditures. The estimates are used to calculate total expenditure and own price elasticities for different household groups. The results indicate that sociodemographic characteristics exert an important influence on the level and composition of food expenditure and on food demand elasticities. Therefore, if demand analysis shall contribute to the design of comprehensive food and social policies, not only average estimates for the population as a whole, but estimates for specific population groups should be considered.

description: Rhus species are known in traditional medicine for their therapeutic virtue and their extracts showed numerous important properties including antimalarial, antimicrobial, antiviral, and hypoglycemic and anticonvulsant activi- ties. Rhus tripartitum (Ucria) is a medicinal plant widely used in Tunisia folk medicine against chronic diarrhea and gastric ulcer. This study was designed to examine in vitro and ex vivo antioxidant, anti-inflammatory and anticancer activities of four extracts of Rhus tripartitum root cortex with increasing solvent polarity (hexane, di-chloromethane, methanol and water). HPLC was used to identify and quantify phenolic compounds in Rhus ex- tract. Water extract showed the highest antioxidant activity using oxygen radical absorbance capacity (ORAC method) with 8.95 ± 0.47 µmol Trolox/mg and a cell based-assay with 0.28 ± 0.12 µmol Trolox/mg as compared to the other fractions. Moreover, methanol extract displayed the strongest anti-cancer activity against human lung carcinoma (A-549) and colon adenocarcinoma cell lines (DLD-1) with an IC50 value of 60.69 ± 2.58 and 39.83 ± 4.56 µg/ml (resazurin test) and 44.52 ± 5.96 and 55.65 ± 6.00 µg/ml (hoechst test), respectively. Besides, the highest anti-inflammatory activity, inhibiting nitric oxide (NO) release, was exhibited by dichloromethane extract with 31.5 % at 160 µg/ml in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The HPLC analysis showed that catechol and kaempferol were the major phenolics. These data suggest the richness of all fractions of les with different polarity and confirm the known traditional therapeutics virtues of this species for the treatment of dysentery, diarrhea and gastric ulcer.

description: Der vorliegende Beitrag diskutiert die optimale Organisation der Wasserversorgung unter Berücksichtigung der grundlegenden Gutscharakteristika und der spezifischen Produktions-struktur. Nach einer formalen Beschreibung der einzelnen Produktionsstufen und der realen Organisation des Wassersektors in Deutschland werden kurz verschiedene Modelle zur Sek-tororganisation vorgestellt. Anschließend wird versucht, die Bestimmung der ökonomisch optimalen Betriebs- und Angebotsorganisation zu erläutern. Schließlich werden zentrale öko-nomische Konzepte der Produktionsanalyse und der industriellen Organisation für eine empi-rische Überprüfung am Beispiel der Wasserversorgung beispielhaft modelliert. Es zeigt sich, dass empirisch fundierte Organisationsmodelle bisher keinen Eingang in die aktuelle Liberali-sierungsdiskussion in den Wassersektoren gefunden haben. Im Hinblick auf eine Restruktu-rierung der Wasserversorgung in ländlichen Regionen könnte das sog. 'Pool-Modell' eine Al-ternative zur derzeitigen integrierten Verbundlösung darstellen. ABSTRACT THE ECONOMICS OF (RURAL) WATER SUPPLY: This paper deals with the optimal organisation of the water supplying industry by having a close look on the basic characteristics of water as a economic good as well as the specific structure of production. After the formal description of the individual stages of production and the real organisation of the German water sector, different models for the sector organisation are briefly being considered. Subsequently, the determination of the optimal firm and industry structure is illustrated from the economic point of view. Finally, central economic concepts with respect to production analysis as well as industrial organisation are modelled for an empirical application to the water supplying industry. It is revealed that empirically based organisation models have not been considered in the course of the ongoing discussion on water sector liberalisation so far. The 'pool-model' seems to be a promising alternative with respect to the restructuring of the water supplying industry in rural areas.

description: Schisandrae Fructus, the fruit of Schisandra chinensis (Turcz.) Baill., is widely used in traditional medicine for the treatment of a number of chronic diseases. Although, Schisandrae Fructus was recently reported to attenuate the interleukin (IL)-1β-induced inflammatory response in chondrocytes in vitro, its protective and therapeutic potential against osteoarthritis (OA) in an animal model remains unclear. Therefore, we investigated the effects of the ethanol extract of Schisandrae Fructus (SF) on inflammatory responses and cartilage degradation in a monosodium iodoacetate (MIA)-induced OA rat model. Our results demonstrated that administration with SF had a tendency to attenuate MIA-induced damage of articular cartilage as determined by a histological grade of OA. SF significantly suppressed the production of pro-inflammatory cytokines such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in MIA-induced OA rats. SF also effectively inhibited expression of inducible nitric oxide (NO) synthase and cyclooxygenase-2, thereby inhibiting the release of NO and prostaglandin E2. In addition, the elevated levels of matrix metalloproteinases-13 and two biomarkers for diagnosis and progression of OA, such as cartilage oligomeric matrix protein and C-telopeptide of type II collagen, were markedly ameliorated by SF administration. These findings indicate that SF could be a potential candidate for the treatment of OA.

description: The purpose of the current study was to investigate the potential anti-obesity activity of an enzymatic hydrolysate of velvet antler in inhibiting adipogenesis in 3T3-L1 cells and in high-fat diet (HFD)-fed obese mice. The enzy- matic hydrolysate was prepared using the commercial food grade protease, Protamex. The velvet antler Protamex hydrolysate (VAPH) indicated profound inhibitory effects on adipogenesis dose-dependently by decreasing the accumulation of triglycerides and down-regulating expression levels of adipogenesis-related proteins C/EBPα, SREBP-1, and PPARγ. In a mouse model of HFD-induced obesity, oral administration of VAPH (100 and 300 mg/kg for 13 weeks) significantly reduced the body weight gain that had resulted from the HFD. VAPH treat- ment also lowered the serum glucose and triglyceride levels, while increasing the HDL-C level. Furthermore, the treatment greatly reduced hepatic lipid droplet accumulation as well as the size of adipocytes. Current findings H has profound anti-obesity effects and could be an effective candidate for preventing obesity and obesity-related chronic diseases.

description: There is good evidence from N-body simulations that the velocity distribution in the outer parts of halos is radially anisotropic, with the kinetic energy in the radial direction roughly equal to the sum of that in the two tangential directions. We provide a simple algorithm to generate such cosmologically important distribution functions. Introducing r_E(E), the radius of the largest orbit of a particle with energy E, we show how to write down almost trivially a distribution function of the form f(E,L)=g(r_E)/L for any spherical model -- including the NFW profile. We in addition give the generic form of the distribution function for any model with a local density power-law index and anisotropy parameter, and provide limiting forms appropriate for the central parts and envelopes of dark matter halos. From those, we argue that, regardless of the anisotropy, the density fall-off at large radii must evolve to 1/r^4 or steeper ultimately.

description: The detection of phosphine (PH3) in the atmosphere of Venus has been recently reported based on millimeter-wave radio observations (Greaves et al. 2020), and its re-analyses (Greaves et al. 2021a/b). In this Matters Arising we perform an independent reanalysis, identifying several issues in the interpretation of the spectroscopic data. As a result, we determine sensitive upper-limits for PH3 in Venus' atmosphere (>75 km, above the cloud decks) that are discrepant with the findings in G2020 and G2021a/b. The measurements target the fundamental first rotational transition of PH3 (J=1-0) at 266.944513 GHz, which was observed with the James Clerk Maxwell Telescope (JCMT) in June 2017 and with the Atacama Large Millimeter/submillimeter Array (ALMA) in March 2019. This line's center is near the SO2 (J=309,21-318,24) transition at 266.943329 GHz (only 1.3 km/s away from the PH3 line) which represents a potential source of contamination. The JCMT and ALMA data, as presented in G2020, are at spectral resolutions comparable to the frequency separation of the two lines. Moreover, the spectral features identified are several km/s in width, and therefore do not permit distinct spectroscopic separation of the candidate spectral lines of PH3 and SO2. We present the radiative transfer modelling we have performed and then discuss the ALMA and JCMT analyses in turn.
CAN ECONOMETRIC ANALYSIS MAKE (AGRICULTURAL) ECONOMICS A HARD SCIENCE? CRITICAL REMARKS AND IMPLICATIONS FOR ECONOMIC METHODOLOGY

description: This paper argues that mainstream economics does not follow the positivist research tradition it (often implicitly) claims to follow and expresses some serious doubt that econometrics in particular can make economics a hard science. Mathematical rigour and sophisticated statistical techniques may be regarded as persuasive analytical tools in economics, but their mere application does not guarantee good research practice. The paper outlines an alternative methodological view of pragmatic instrumentalism in which the well known tools of economic analysis can find a new place. Instead of relying on a narrow rule that purports to produce universal truth, this view encourages to increase the target area for questioning and probing. Much more attention is paid to the communicative aspects of scientific methodology  in which terms an analysis is framed, and under what conditions, to whom, by whom, and by which means it is articulated. ZUSAMMENFASSUNG MACHT DIE ÖKONOMETRIE DIE (AGRAR-) ÖKONOMIE ZU EINER HARTEN WISSENSCHAFT? Der Beitrag vertritt den Standpunkt, dass die Wirtschaftswissenschaften nicht der positivistischen Forschungstradition folgen, der sie (oft implizit) vorgeben zu folgen. Darüber hinaus wird Zweifel geäußert, dass die Ökonometrie im Besonderen in der Lage ist, die Ökonomie zu einer harten Wissenschaft zu machen. Mathematische Stringenz und anspruchsvolle statistische Verfahren mögen als überzeugende Analyseinstrumente der Ökonomie gelten, allein ihre Anwendung garantiert jedoch noch keine gute Forschungspraxis. Der Beitrag skizziert eine alternative Betrachtungsweise, die einem pragmatischen Instrumentalismus folgt und in der die bekannten Instrumente der ökonomischen Analyse einen neuen Platz finden können. Anstatt auf eine enge Regel zu vertrauen, die vorgibt, universelle Wahrheiten hervorzubringen, sollte die Zielfläche für das Hinterfragen und Nachforschen vergrößert werden. Wesentlich mehr Aufmerksamkeit wird den kommunikativen Aspekten wissenschaftlicher Arbeit gewidmet  mit Hilfe welcher Begriffe eine Analyse vorgenommen wird, und unter welchen Bedingungen, im Hinblick auf wen, durch wen und auf welche Weise sie artikuliert wird.
