Opis:
The resistance of network supply chains to disruptions is the very important exploratory area. Moreover, from the perspective of individual chain links forming a network supply chain, an essential issue is the skill of adapting itself to variable conditions of the environment and changes in the structure of the chain itself. The article took into consideration both of the exploratory areas: the resistance of network supply chains to disruptions and adaptive strategies of chain links in a supply chain.

Opis:
W artykule poruszam zagadnienie pułapek pojawiających się w pracy z kategorią oporu i jej zastosowaniem w analizach teoretycznych oraz empirycznych. Prezentuję różne ujęcia tego pojęcia oraz omawiam jego wieloaspektowość i kontekstowość. W ramach pracy z tą kategorią wyłoniła się problematyka jej polaryzacji. Zjawisko to z jednej strony powoduje rozmycie kategorii oporu, z drugiej zaś może przyczynić się do jej nadmiernego zawężenia. Zarówno w jednym, jak i w drugim przypadku pojawia się ryzyko dostrzegania oporu w każdej sytuacji lub ignorowania jego wyraźnych przejawów. Celem tekstu jest ukazanie trudności w pracy ze złożoną kategorią teoretyczną i empiryczną, jaką niewątpliwie jest „opór” oraz omówienie pułapek wynikających z braku wnikliwej analizy literatury a także krytycznej refleksji nad studiami teoretycznymi i praktycznymi dotyczącymi danego pojęcia i terminów z nim związanych.
The article addresses the issue of pitfalls which appear during work with the category of resistance and its application in theoretical and empirical analyses. The article presents different perspectives on this notion and discusses its multidimensional character and contextuality. What emerged from the work with that category is its polarization. This phenomenon blurs the category of resistance, at the same time contributing to its excessive limitation. In both cases, there is a risk of recognizing resistance in every situation or ignoring its explicit displays. The aim of the article is to show the struggles of working with a complex theoretical and empirical category that is “resistance” as well as to discuss the pitfalls resulting from the lack of athorough literature analysis and a critical reflection on theoretical and practical studies concerning a given concept and terms connected to it.

Opis:
The main subject of the analysis was the activity and political concepts of lay Cath-olics who operated on the Polish political scene in the 1980s. This group of Catholic activists had been active in the public sphere for many years; in the 1980s, they orga-nized themselves in a Polish Catholic-Social Union. This community was not among the most important political parties of the then political system; it was not a major factor stabilizing the system or a major source of change. Nevertheless, it did have a prominent feature – it had a parliamentary representation and participated in political practice; it also had a limited impact on political decisions. The main motive of their actions was to promote Catholic values in the public sphere, but also an attempt to create a Catholic party, in the right circumstances. Still, there is a disagreement, both among researchers and actors of the political scene of the time, about the clear-cut assessment of their politi-cal commitment. Nonetheless, it probably can be said that their attitudes are within the concept of semi-opposition and paralegal opposition, and, to some extent, in what we understand by the term of opposition of value systems.

In the network society, the media symbols becomes a meta-commentary, which may result in changes and transformations both in virtual and real area. The text is a reflection on the three aspects of the properties of the hashtag. The message is described as a tool for change, community opposition and the community of the thinks. This point of view gives the opportunity to demonstrate the interdependence that prevail in online subcultures of resistance.

Opis:
Neuraminidase inhibitors (NAIs) are antiviral drugs for treatment and prophylaxis of influenza. By blocking the activity of the enzyme neuraminidase, NAIs prevent new viral particles from being released. The increasing use of NAIs brings into focus the risk of drug resistance arising to the class. There are three levels of antiviral resistance according to the way that resistance can be detected or inferred: genotypic, phenotypic and clinical resistance. For many years seasonal influenza viruses resistance to NAIs was low (0.33%). Recently, there has been described an increasing number of resistant seasonal influenza strains to oseltamivir (2% in adults, 5-18% in children). In 2007 there were published data describing 14% resistant to oseltamivir strains of influenza A/H1N1/ in Europe. Approximately 0.5-1.0% of influenza A/H1N1/pdm09 isolates are currently resistant to oseltamivir. The established markers of the resistance to oseltamivir were found in 2.4% of human and 0.8% of avian isolates of influenza A/H5N1/. It has been not observed a cross resistance among oseltamivir and zanamivir. NAIs resistance in influenza viruses is relative and despite its presence patients with resistant viruses may still benefit from receiving these antivirals. The response to treatment with antivirals remains the most important proof of antiviral effectiveness. The rational use of NAIs is essential to preserve the best choice for treatment and prophylaxis of seasonal, avian and pandemic influenza.

Opis:
An increase in the antibiotic resistance among Enterococcus faecium strains has been observed worldwide. Moreover, this bacteria has the ability to produce several virulence factors and to form biofilm that plays an important role in human infections. This study was designed to compare the antibiotic resistance and the prevalence of genes encoding surface protein (esp), aggregation substance (as), surface adhesin (efaA), collagen adhesin (ace), gelatinase (gelE), and hialuronidase (hyl) between biofilm-producing and non-producing E. faecium strains. Therefore, ninety E. faecium clinical isolates were tested for biofilm-forming ability, and then were assigned to two groups: biofilm-positive (BIO+, n =70) and biofilm-negative (BIO-, n = 20). Comparison of these groups showed that BIO+ isolates were resistant to β-lactams, whereas 10% of BIO- strains were susceptible to ampicillin (statistically significant difference, p = 0.007) and 5% to imipenem. Linezolid and tigecycline were the only antibiotics active against all tested isolates. Analysis of the virulence factors revealed that ace, efaA, and gelE genes occurred more frequently in BIO- strains (ace in 50% BIO+ vs. 75% BIO-; efaA 44.3% vs. 85%; gelE 2.9% vs. 15%, respectively), while hyl gene appeared more frequently in BIO+ isolates (87.1% BIO+ vs. 65% BIO-). These differences were significant (p < 0.05). We concluded that BIO+ strains were more resistant to antibiotics than BIO- strains, but interestingly, BIO- isolates were characterized by possession of higher virulence capabilities.

Opis:
This review summarizes current data on resistance among Salmonella spp. isolates of food origin from countries in different regions of the world. The mechanisms of resistance to different groups of antimicrobial compounds are also considered. Among strains resistant to quinolones and/or fluoroquinolones the most prevalent mechanism is amino acid substitutions in quinolone resistance-determining region (QRDR) of genes gyrA, parC but mechanism of growing importance is plasmid-mediated quinolone resistance (PMQR) associated with genes qnrA, qnrB, qnrC, qnrD, qnrS but frequency of their detection is different. Resistance to sulfonamides is mostly associated with genes sul1 and sul2, while resistance to trimethoprim is associated with various variants of dhfr ( dfr) genes. Taking into account Salmonella spp. strains isolated from food, resistance to β-lactams is commonly associated with β-lactamases encoding by blaTEM genes. However strains ESBL and AmpC – positive are also detected. Resistance to aminoglicosides is commonly result of enzymatic inactivation. Three types of aminoglycoside modifying enzyme are: acetyltransferases (AAC), adenyltransferases (ANT) and phosphotransferases (APH). Resistance to tetracyclines among Salmonella spp. isolated from food is most commonly associated with active efflux. Among numerous genetic determinants encoding efflux pumps tetA, tetB, tetC, tetD, tetE and tetG are reported predominatingly. One of the most common mechanisms of resistance against chloramphenicol is its inactivation by chloramphenicol acetyltrasferases (CATs), but resistance to this compound can be also mediated by chloramphenicol efflux pumps encoded by the genes cmlA and floR. It is important to monitor resistance of Salmonella isolated from food, because the globalization of trade, leading to the long-distance movement of goods, animals and food products, encourages the spread of resistant pathogens around the world.
W artykule przedstawiono aktualne dane na temat mechaniznów lekooporności pałeczek Salmonella spp. pochodzących z żywności. Wśród szczepów opornych na chinolony i/lub fluorochinolony najczęściej identyfikowanym mechanizmem są substytucje aminokwasów w obrębie regionów determinujących oporność na chinolony (QRDR-quinolone resistancedetermining region) w genach gyrA i parC, jednak coraz częściej identyfikowane są geny qnr (qnrA, qnrB, qnrC, qnrD, qnrS) związane z plazmidami (PMQR - plasmid-mediated quinolone resistance). Oporność na sulfonamidy jest najczęściej związana z genami sul1 i sul2, natomiast różne warianty genów dhfr ( dfr) warunkują oporność na trimetoprim. Biorąc pod uwagę szczepy Salmonella spp. pochodzące z żywności, oporność na antybiotyki β-laktamowe związana jest zazwyczaj z produkcją β-laktamaz kodowanych przez geny blaTEM. Jednakże coraz powszechniej identyfikowane są szczepy produkujące β-laktamazy o rozszerzonym spektrum substratowym (ESBL) oraz cefalosporynazy AmpC. Oporność na aminoglikozydy najczęściej wynika z wytwarzania enzymów modyfikujących cząsteczki leku: acetylotransferaz (AAC), adenylotransferaz (ANT) oraz fosfotransferaz (APH). Oporność wobec tetracyklin wśród pałeczek Salmonella spp. izolowanych z żywności najczęściej związana jest z mechanizmem aktywnego usuwania leku za pomocą pomp (efflux) kodowanych, najczęściej przez geny tetA, tetB, tetC, tetD, tetE i tetG. Jednym a najczęściej wykrywanych mechanizmów oporności na chloramfenikol jest jego inaktywacja w wyniku działania acetylotransferazy chloramfenikolowej (CAT). Oporność na chloramfenikol może być również związana ze zjawiskiem aktywnego wypompowywania leku. Pompy efflux są kodowane przez geny floR (warunkujące oporność także na florfenikol) lub cml. Istotne znaczenie ma monitoring lekooporności wśród szczepów Salmonella spp. pochodzących z żywności, ponieważ transport środków spożywczych oraz zwierząt do i z krajów całego świata ułatwia rozprzestrzenianie się szczepów lekoopornych.

Opis:
Fusarium head blight resistance (FHB) can be achieved by using improved adapted varieties as crossing partners or by a marker-assisted introgression of mapped QTL from non-adapted sources. In this long-term study Fhb1 on chromosome 3BS and Qfhs.ifa-5A located on chromosome 5A were introgressed into European elite spring and winter wheat to test effects on FHB resistance and side effects on agronomic performance and F. graminearum isolates and mixtures. The introgression of the QTL Fhb1 and Qfhs.ifa-5A from the Sumai 3-descendant CM82036 could be performed in the shortest possible way by marker-assisted backcrossing. They were both validated in European elite wheat background. Effects on FHB resistance were, on average, only about half of the effect in the original mapping populations. In the best phenotypically and marker-selected BC0 line of spring wheat FHB was reduced from 40 to 4.3% of disease symptoms by introgressing both QTL, in the best BC3 line of winter wheat the reduction was 28 and 37% for the moderately resistant and highly susceptible recurrent parent, respectively. Introgression of both QTL simultaneously did not result in significantly higher FHB resistance than introgression of only one of both QTL. Small significant negative effects on grain yield were detected in the Anthus but not in the Opus BC3F2:5 backcross population when both QTL were introgressed. Backcrossing with only Qfhs.ifa-5A did not reduce grain yield significantly. Differences in heading date, plant height and quality traits were in all cases small although often significant. Selection of lines with improved resistance level and similar high yield level like the recurrent parent was feasible. Stability of FHB resistance mediated by both QTL was stable across 22 Fusarium isolates from Europe and Canada and six binary mixtures. Competition effects between isolates in mixtures were obvious but could not be attributed to the resistance of the host. In conclusion, marker-based backcrossing is a feasible option for introgressing Fhb1 or Qfhs.ifa-5A QTL into the high-yielding, quality-oriented European wheat gene pool.

While Kurdish sportspeople are not discouraged from joining in sports activities, their participation is heavily monitored by the government agencies against any manifestation of ethnic identity. Football in the Kurdish regions, seen by the Turkish state as a tool to distract Kurdish youth from political activities, has always been subject to the direct intervention of the civil and military bureaucracy, their presence in club boards is not uncommon. However, a third-division club named Amedspor, challenged all the unwritten rules related to Kurds in sports, at the expense of receiving a recurring suspension from the Turkish Football Federation. This article examines the Kurdish sports and the Amedspor case through Manuel Castells’ conception of legitimizing, resistance and project identities

Opis:
Dalit life-writings have often been identified as reified spaces of protest against the Brahmanic oppression continuing since centuries in the Indian society. Banished to a space of invisibility, both metaphorical as well as physical margins of the Social Imaginary, Dalits continue to push back boundaries by transforming the ‘marginal’ space into a space of ‘subaltern resistance’. My aim in this paper is to interrogate the methods of collective resistance in the life-writings of Dalit women authors and show how the peripheral spatial geography becomes the central site of resistance. Both Baby Kamble’s The Prisons we Broke (2008), and Bama’s Karukku (1992) belong to entirely different historical periods, and therefore, inevitably differ in their plot-narratives and manner of expression. However, they converge in their emphasis on how the Dalit segregated spaces in their village assume an important role in awakening their collective consciousness first – as members of a community, and second – as women. Both Karukku and The Prisons We Broke refuse to adhere to the Augustinian definitions of the autobiography as a genre and instead become works which elude generic conventions of the autobiography, anticipating a separate literary genre for themselves. In fact, the closest literary referent of these texts is the Latin American genre of the testimonio - social and political narratives of witnessing significant events as a collective -  that emerged in the 1960s. Reading these Dalit life-writings as testimonios of collective resistance is evocative of the on-going struggle of the Dalits to claim a separate space, both social and literary, while lending a voice to their lived-experiences in a paternalistic society that is essentially casteist.    Baby Kamble and Bama raise pertinent questions against the dominant religious ideology and contribute to a social change in the conditions of women. Thus, my second intention in the paper is to closely look at the resistance offered against religious bias by the two authors. Since the Indian caste system derives its justifications from the Hindu law of divinity that are apparently inalterable according to Hindu purists, challenging the ‘savarna’ customs and rituals has been a persistent preoccupation within Dalit activism. Foregrounding textual instances of such challenges and resistance shall help us in understanding how a society practices coercion against a community when it comes to something as benign and as personal as man’s spiritual connection with the divine force.

Opis:
Genetic resistance against Pythium species would be an efficient control of this major seed and seedling fungal pathogen in safflower (Carthamus tinctorius), but so far no source has been identified. Therefore, identifying and then incorporating genetic resistance into the cultivars would be an ideal method of control for this disease. So in this study the resistance to seed rot and damping-off caused by Pythium ultimum among seventeen genotypes of safflower collected from all major production regions of the crop in Iran and some other countries was investigated. Pythium ultimum, previously identified as the most prevalent Pythium isolates on safflower, were used to infest the sterilized soil, which was seeded with safflower genotypes in greenhouse conditions. The experiment was conducted as a split plot design in which sterile and Pythium-infested soils were considered as main plots, and seventeen genotypes of safflower were sub plots. In sterile media, percent of seedling emergence (SES) and in Pythium-infested media, percent of seedling emergence (SEI), percent of diseased seedlings (DSI), percent of uninfected seedlings (USI) and percent of non-emerged seeds (NSI) were recorded. Symptoms showed that in safflower, damping-off occurred in both forms of pre and post emergence. Genotypic variation was existed for level of susceptibility to P. ultimum. Significant differences in SES and SEI were detected among safflower genotypes (P < 0.01), and a significant correlation between SES and seed weight (P < 0.05); SES with SEI (P < 0.05) were detected. Result showed that between evaluated genotypes there wasn’t any genotype with complete resistance (100%) to P. ultimum, so the susceptibilities were assayed. Based on the assessed variables, genotypes LRV-55-295, Aceteria, PI-250537 and IL-111 appear to be highly susceptible to the Pythium infection, whereas 34040, Arak281, and Isfahan were the least susceptible to the disease. Further research will be conducted to determine whether the resistance detected in these genotypes is heritable...

The text undertakes the problematics situated between modernity and tradition regarding the reception of H.A. Giroux’s works in Poland, in a view of furthering the study of pedagogy and educational praxis. First, the author outlines the beginnings of openness towards critical pedagogy. What is underscored here is the 1980s’ main inspiration drawn from the resistance paradigm. Then, the author proceeds to the current state of Giroux’s reception in Poland. He illustrates differences among particular examples and levels of the said reception of Giroux’s pedagogy and of the scholar’s theoretical background. The emphasized disputes pertain especially to transcending metaphysics and relativism as a challenge faced by hermeneutical criticism and critical hermeneutics. Additionally, the “critical” horizon of the main handbook of pedagogy used in Polish universities is discussed. The author point to the wasteful efforts at instigating the breakthrough in the reception of critical pedagogy and he exemplifies them by an instance of misbegotten analysis of the allegedly delayed critical pedagogy of work. As a particularly positive example the author presents a new effort at developing critical hermeneutics (and radical praxis) for pedagogy by Andrzej Wierciński. In the concluding part written “in lieuof conclusions,” four lists of critical problems’ dislocations are provided; the problems are both convergent and related to one another, thereby redefining current research objectives and pertain to practical applications in educational praxis.
