(Fig. 17)
Material examined. 1 ♀, 2 ♂♂ (MNHN-IU-2017-2160) and 1 dissected ♀ (figured) from Polycarpa pomaria (Savigny, 1816), MEDITS 2016, Stn M16-2 (43°20.98 Ń, 4°19.64 É), depth 32–33m, 31 May 2016.
Diagnostic characters of female. Body (Fig. 17A) small, 1.61 mm long. Abdominal somites much shorter than wide. Caudal ramus (Fig. 17B) shorter than wide (44×48 μm) and shorter than anal somite (52×126 μm); all caudal setae positioned distally.
Rostrum (Fig. 17C) taperingtowardsangular tip. Antennule 15-segmented. Two exopodal setae of antenna (Fig. 17D) subequalin length.
Mandibular endopod with 4 and 9 setae on first and second segments, respectively. Endopod of maxillule 2-segmented with 2 and 3 setae on first and second segments, respectively. Maxilla with 3 setae on first endite of syncoxa and with 3 setae on terminal segment of endopod. Maxilliped armedwith 10, 1, and 3 setae on first to third segments, respectively.
Leg 5 (Fig. 17E) protopod broad, ornamented with about 10 spinules along inner margin and prominent outer process with subdistal tooth on inner margin; exopodal segment 15×16 μm, subcircular, shorter than outer process of protopod, and armedwith 1 spineand 1 seta.
Remarks. This distinctive species is unique in the genus in having short caudal rami. They are shorter than wide in N. prasina whereas in all other known species of Notodelphys the caudal rami are at least 1.6 times longer than wide. This species has a similar distribution to the preceeding species, extending from Scandinavia, alongthe coast of northwestern Europe and into the Mediterranean (Illg, 1958; Illg & Dudley, 1961).

description: As the world's largest carbon resources country with relatively great carbon emission, China in has just started its carbon trade. China is only a passive participant in international carbon trading market, rarely participating in the project of Clean Development Mechanism (CDM). Therefore, trade market of emission permits can be divided into first and second trade markets. During the definition of emission right, we found out that the ways of emission trade at second carbon trade market is the key to the research on carbon trade, which can realize the allocation efficiency and utilization efficiency of resources. Then, feasibility of implementing auction system of emission permits trade in China is analyzed from the aspects of legal protection, technical support, and supervision and management. Chatterton and Samuelson double action model is adopted to determine the market strike price for market clearing. In this auction, a seller and a buyer offer the asking price and bid price for a unit of emission permits, respectively. And the bidding strategy is determined in order to obtain the maximum profit for both seller and buyer. Game Model for carbon emission permits is established. Finally, allocation efficiency of emission permits trade market of carbon is studied and the Nash Equilibrium in this model is analyzed, so as to provide theoretical references for emission permits trade of carbon in China.

description: We provide a determinantal formula for tau-functions of the KP hierarchy in terms of rectangular, constant matrices $A$, $B$ and $C$ satisfying a rank one condition. This result is shown to generalize and unify many previous results of different authors on constructions of tau-functions for differential and difference integrable systems from square matrices satisfying rank one conditions. In particular, it contains as explicit special cases the formula of Wilson for tau-functions of rational KP solutions in terms of Calogero-Moser Lax matrices as well as our previous formula for KP tau functions in terms of almost-intertwining matrices.

description: The main objective of this work is to characterize the pathwise local structure of solutions of semilinear stochastic evolution equations (see's) and stochastic partial differential equations (spde's) near stationary solutions. Such characterization is realized through the long-term behavior of the solution field near stationary points. The analysis falls in two parts I, II. In Part I (this paper), we prove a general existence and compactness theorem for $C^k$-cocycles of semilinear see's and spde's. Our results cover a large class of semilinear see's as well as certain semilinear spde's with non-Lipschitz terms such as stochastic reaction diffusion equations and the stochastic Burgers equation with additive infinite-dimensional noise. In Part II of this work ([M-Z-Z]), we establish a local stable manifold theorem for non-linear see's and spde's.

description: In this paper customer loyalty will be examined with the help of budget ratios (budget shares). We address the question whether sociodemographic groups differ in their shopping behavior and their store loyalty. Loyalty is analyzed with regard to the ten largest food retail chains in Germany in 2002. It is shown that the loyalty of customers depends on the lifecycle stage of the household and household size for the most part. Older and single households are more loyal than younger families.

Zunächst legt er einige generelle Ausgangsannahmen dar, um anschließend überblickshaft auf die betrieblichen Geschlechterverhältnisse in der DB AG einzugehen und zu zeigen, wo verallgemeinerbare Probleme und Blockaden für einen geschlechtergerechten Wandel der betrieblichen Geschlechterverhältnisse und für den Aufstieg von Frauen in Führungspositionen liegen. Darauf aufbauend diskutiert er geschlechtertypische Dilemmata zwischen Erwerbsarbeit und individuellen (familialen) Reproduktionsansprüchen. Das wird im Kontext einer ‚reflexiven Karriereorientierung‘ näher beleuchtet, die vor allem, aber nicht mehr nur bei weiblichen* Fach- und Führungskräften zu beobachten ist. Als Sozialkompetenz zielt sie auf den Erhalt eines subjektiv als ganzheitlich erlebbaren Lebenszusammenhanges und stellt eine Kritik an der traditionellen Arbeits- und Leistungskultur dar. Der Beitrag endet mit einem Plädoyer für eine an den komplexer werdenden Lebenszusammenhängen von Frauen* und Männern* orientierte Re-Thematisierung betrieblicher Geschlechterpolitik.

Die quantitative Studie setzt sich auf der Grundlage einer Sekundäranalyse mit Statistiken zum Empfang behinderungsspezifischer Ressourcen auseinander. Die qualitative Studie zielt mittels ExpertInneninterviews auf die Sinnkonstruktionen sog. Gatekeeper (TorwächterInnen) bei der Vergabe behinderungsspezifischer Ressourcen. In quantitativer Hinsicht besteht u. a. ein Ungleichgewicht in den Geschlechterverhältnissen. In qualitativer Hinsicht zeigt sich, dass die Zuschreibung von Behinderung und damit die Entscheidung über den Zugang zu behinderungsspezifischen Leistungen nicht allein auf der Kategorie Behinderung fußen, sondern dabei auch andere Kategorien als Sinndimensionen eine wichtige Rolle spielen. In diesem Zusammenhang wird unter verschiedenen Gesichtspunkten auch die Verbindung von Gatekeeping und sozialer Ungleichheit untersucht sowie das Konzept des Othering kritisch beurteilt.

description: Although Greek wine is a high quality product, it is not well known in the international marketplace and it has not a recognised brand name. The aim of the current research is to examine the barriers to the export of Greek wine. In-depth Personal interviews were undertaken with producers, managers and people involved in the Greek wine industry. Participants provided information about the current situation and their projections about future. This research is based on qualitative methods. According to the results of the research the barriers could be separated into three basic categories, logistic and financial barriers, marketing and promotion barriers and policy barriers. This research offers Greek wine export managers and people involved in wine industry in general a possible mean of evaluating the marketing potentials of Greek wine in the international marketplace. It also helps Greek wine export managers to identify and recognise the problems that their product face in the international market, in order to improve its image, to conduct a brand building strategy and as a result to increase the exports.

description: Religious leaders are highly influential actors in many societies across the globe. In the singular global crisis brought upon by the Covid-19 pandemic, their perspective on the pandemic itself but also the post-pandemic future is of high relevance. Against this background, the Research Programme on Religious Communities and Sustainable Development conducted the Religious Leaders’ Perspectives on Corona Survey, a comprehensive survey of 1200 religious leaders globally, in 2020/2021. Its aim was to investigate the role of religious communities and religious leaders during the Covid-19 pandemic. This report provides an outline of the survey methodology and the resultant dataset and highlights key results. It emerges that the Covid-19 pandemic was not primarily a health crisis. Rather, in terms of its consequences Covid-19 had the characteristics of a primarily economic crisis in the global South and a primarily psychosocial crisis in the Global North. Moreover, the pandemic has had a fundamental impact on religious practice across the globe. This impact, however, seems to be highly unequal between the Global South and North. Religious communities are shown to have had an important role as civil society actors in the pandemic, providing both psychosocial and material support. Regarding the post-pandemic worlds, religious leaders envision a more equitable society and emphasize the need for environmental sustainability.

description: The weak lensing magnification of Type Ia Supernovae (SNe Ia) is sensitive to the clustering of matter, and provides an independent cosmological probe complementary to SN Ia distance measurements. The Nancy Grace Roman Space Telescope is uniquely sensitive to this measurement as it can discover high redshift SNe Ia and measure them with high precision. We present a methodology for reconstructing the probability distribution of the weak lensing magnification $μ$ of SNe Ia, $p(μ)$, from observational data, and using it to constrain cosmological parameters. We find that the reconstructed $p(μ)$ can be fitted accurately by a stretched Gaussian distribution, and used to measure the variance of $μ$, $ξ_μ$, which can be compared to theoretical predictions in a likelihood analysis. Applying our methodology to a set of realistically simulated SNe Ia expected from the Roman Space Telescope, we find that using the weak lensing magnification of the SNe Ia constrains a combination of matter density $Ω_m$ and matter clustering amplitude $σ_8$. SN Ia distances alone lead to a better than 1\% measurement of $Ω_m$. The combination of SN Ia weak lensing magnification and distance measurements result in a $\sim$ 10\% measurement on $σ_8$. The SNe Ia from Roman will be powerful in constraining the cosmological model.

description: In this paper an estimate is made concerning the correlation between the prosperity and viability of food enterprises and the volume of fixed assets. The amount of investment in fixed assets refers to the volume of the food cooperative activities. Hence, it can be considered as a comprehensive indicator which shows the size and use orientation of enterprises. The financial activity results and efficiency of the cooperatives depend, in many respects, on investments in the floating funds and fixed assets, the size of investment in monetary units and materials and the optimum ratio between them. This paper provides a financial assessment and comparative analysis of the food marketing cooperatives, against the amount of the fixed assets they have. The main purpose of this research is to estimate the viability of food marketing cooperatives under competitive conditions in the agricultural sector and to evaluate the financial aspects of their activities in terms of the size of fixed assets. The research provides a brief overview of the European Union experience from the financial side of cooperative activities. But due to the huge size of the EU and the significant differences between the various countries, it is difficult to estimate the issue on a union scale. Instead, some general features are mentioned briefly with reference to Greek cooperation, with more specific and detailed data and analyses provided for several cooperatives located in Crete. Crete was chosen for this research because it is one of the largest food producing regions in Greece. The comparative analysis was carried out based on the data for four consecutive years (from 2003 to 2006). For the purpose of this study, cooperatives functioning in Crete were chosen. The aim of the current research was to determine the interdependence between the size of the fixed assets and the welfare of the cooperatives and to underline the optimum amount of assets for marketing cooperatives, based on the ranking of the enterprises.

description: Cooperatives and investor-owned firms are alternative forms of business organisation that coexist and compete in many markets. The theoretical literature has identified a number of comparative advantages and disadvantages of cooperatives. Decentralized decision making within cooperatives may lead to quality coordination problems (free-riding on product quality), for example: whereas the individual member has to bear the full costs associated with higher quality, the benefits of delivering higher quality will be shared among all members. The present paper investigates this free-riding problem in determining product quality within a marketing cooperative in a vertically related market (food chain). On the basis of a mixed-oligopoly model, we show that the free-rider problem in the supply of high-quality products might be strong enough to ensure that cooperatives will never supply higher quality than investor-owned firms. Whether the cooperative can overcome the free-riding problem and supply a final product of high quality is shown to depend on the consumer’s valuation of quality, the costs of producing high quality, the way in which the quality of the final product is determined from the quality levels of the inputs delivered, the possibilities in controlling product quantity as well as on the number of members of the cooperative.
On the evolutionary status of Be stars. I. Field Be stars near the Sun

description: A sample of 97 galactic field Be stars were studied by taking into account the effects induced by the fast rotation on their fundamental parameters. All program stars were observed in the BCD spectrophotometric system in order to minimize the perturbations produced by the circumstellar environment on the spectral photospheric signatures. This is one of the first attempts at determining stellar masses and ages by simultaneously using model atmospheres and evolutionary tracks, both calculated for rotating objects. The stellar ages ($τ$) normalized to the respective inferred time that each rotating star can spend in the main sequence phase ($τ\_{\rm MS}$) reveal a mass-dependent trend. This trend shows that: a) there are Be stars spread over the whole interval $0 \la τ/τ\_{\rm MS} \la 1$ of the main sequence evolutionary phase; b) the distribution of points in the ($τ/τ\_{\rm MS},M/M\_{\odot}$) diagram indicates that in massive stars ($M \ga 12M\_{\odot}$) the Be phenomenon is present at smaller $τ/τ\_{\rm MS}$ age ratios than for less massive stars ($M \la 12M\_{\odot}$). This distribution can be due to: $i$) higher mass-loss rates in massive objets, which can act to reduce the surface fast rotation; $ii$) circulation time scales to transport angular momentum from the core to the surface, which are longer the lower the stellar mass.

description: We investigate the equal-time (static) quark propagator in Coulomb gauge within the Hamiltonian approach to QCD in $d=2$ spatial dimensions. Although the underlying Clifford algebra is very different from its counterpart in $d=3$, the gap equation for the dynamical mass function has the same form. The additional vector kernel which was introduced in $d=3$ to cancel the linear divergence of the gap equation and to preserve multiplicative renormalizability of the quark propagator makes the gap equation free of divergences also in $d=2$.
An embeded tree data model for web content adaptation
Creators: name: Wang, Yanming
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents a novel data model named Content Container Tree (CCT) to enable dynamic web content adaptation for heterogeneous terminal devices. The rationale for the CCT data model is that a web page can be visually divided into several segments and each segment can be iteratively divided into several smaller sub-segments until certain granularity level has been reached; the hierarchy of the web page segments can be expressed with a tree structure; thus, by traversing this segmentation tree, the user can find and locate a particular segment of interest which is at the dimension comparable to the screen size of the terminal device. The CCT data model organizes the semantics of the hierarchical content segments with a tree structure and embeds this semantic tree into the content DOM tree to enable the user to navigate through the content segments at different levels and retrieve the target content segment according to their semantics. Based on the CCT data model, the high level structural adaptation can be explicitly separated from the low level presentational adaptation, resulting in a highly modular and extensible framework for web content adaptation which is proposed in this thesis too. The CCT web content adaptation approach is distinguished from other approaches in the following aspects: first, the CCT approach is data oriented rather than process oriented; second, the CCT approach supports multilevel granularity of the contents; finally, CCT approach is dynamic; result pages can be generated on the fly by request. As an empirical evaluation, a content adaptation application is built according to the CCT adaptation framework to show the feasibility and effectiveness of our approach.

description: We characterize the symmetry algebra of the generic superintegrable system on a pseudo-sphere corresponding to the homogeneous space $SO(p,q+1)/SO(p,q)$ where $p+q={\cal N}$, ${\cal N}\in\mathbb N$. We show that this algebra is independent of the signature $(p,q+1)$ of the metric and that it is the same as the Racah algebra ${\cal R}({\cal N}+1)$. The spectrum obtained from ${\cal R}({\cal N}+1)$ via the Daskaloyannis method depends on undetermined signs that can be associated to the signatures. Two examples are worked out explicitly for the cases $SO(2,1)/SO(2)$ and $SO(3)/SO(2)$ where it is shown that their spectrum obtained by means of separation of variables coincide with particular choices of the signs corresponding to the specific signatures of the spectrum for the symmetry algebra ${\cal R}(3)$.

description: In this paper, we have outlined the development of an autonomous dynamical system within a general scalar-tensor gravity framework. This framework encompasses the overall structure of the non-minimally coupled scalar field functions for both the torsion scalar ($T$) and the boundary term ($B$). We have examined three well-motivated forms of potential functions and constrained the model parameters through dynamical system analysis. This analysis has played a crucial role in identifying cosmologically viable models. We have analysed the behaviour of dynamical parameters such as equation-of-state parameters for dark energy and the total, as well as all the standard density parameters for radiation, matter, and dark energy to assess their compatibility with current observational data. The phase space diagrams are presented to support the stability conditions of the corresponding critical points. The Universe is apparent in its late-time cosmic acceleration phase via the dark energy-dominated critical points. Additionally, we compare our findings with the most prevailing $Λ$CDM model. The outcomes are further inspected using the cosmological data sets of Supernovae Ia and the Hubble rate H(z).

description: We present results of kinetic lattice Monte Carlo (KLMC) simulations of substitutional arsenic diffusion in silicon mediated by lattice vacancies. Large systems are considered, with 1000 dopant atoms and long range \textit{ab initio} interactions, to the 18th nearest lattice neighbor, and the diffusivity of each defect species over time is calculated. The concentration of vacancies is greater than equilibrium concentrations in order to simulate conditions shortly after ion implantation. A previously unreported time dependence in the applicability of the pair diffusion model, even at low temperatures, is demonstrated. Additionally, long range interactions are shown to be of critical importance in KLMC simulations; when shorter interaction ranges are considered only clusters composed entirely of vacancies form. An increase in arsenic diffusivity for arsenic concentrations up to $10^{19} \text{cm}^{-3}$ is observed, along with a decrease in arsenic diffusivity for higher arsenic concentrations, due to the formation of arsenic dominated clusters. Finally, the effect of vacancy concentration on diffusivity and clustering is studied, and increasing vacancy concentration is found to lead to a greater number of clusters, more defects per cluster, and a greater vacancy fraction within the clusters.

description: This paper investigates the different types of vertical coordination mechanism and the spread institutional arrangements (i.e. contracting) as well as identifies opportunities to expand innovative solutions that help to create and maintain the linkages among the famers and downstream businesses for dairy in Romania. In particular, we address the various modes of access to production factors, such as capital, specific inputs and know-how, as reasons for the varied development of Romanian dairy supply chains and its respective actors (farmers, processors). The paper draws on results from a recent study supported by the World Bank. The findings are based on semi-structured telephone and face-to-face interviews conducted in January-March 2009. The interviews indicate that large and prosperous dairy chains have better access to all production factors, which allows the strengthening of their relationships, especially in the upstream stages (farmers), and supports their competitive advantages in the domestic market. Many barriers exist in the domestic market, particularly for small and medium-sized dairy chains, which hampers their potential exploitation of particular stages in the chain. In the same way the findings indicate that virtually only large companies and farms benefit from public support regarding access to capital (EU-funding, governmental programs) and know-how (extension service).
Thermoelectric calculations of ring-shaped bands in two-dimensional Bi$_2$Te$_3$, Bi$_2$Se$_3$ and Sb$_2$Te$_3$: a comparison of simple scattering approximations

description: Materials with ring-shaped electronic bands are promising thermoelectric candidates, since their unusual dispersion shape is predicted to give large power factors. While previous calculations of these materials have relied on the assumption of a constant mean-free-path or relaxation time, recent first-principles modeling of electron-phonon scattering suggests that the scattering rates may be better approximated by the electron density-of-states (so-called DOS scattering model). In this work, we use density functional theory to investigate single and double quintuple-layer Bi$_2$Te$_3$, Bi$_2$Se$_3$ and Sb$_2$Te$_3$, with a focus on understanding how the three aforementioned scattering approximations impact thermoelectric performance -- emphasis is placed on the DOS scattering model. The single quintuple-layer materials possess two ring-shaped valence band maxima that provide an abrupt increase in conducting channels, which benefits the power factor. Additionally, below the band edge a ring-shaped minimum, located between the two maxima, is found to further enhance the thermoelectric performance but only with the DOS scattering model. This comes from a sharp drop in the DOS, and thus scattering, just below the ring-shaped minimum. An analytic octic dispersion model is introduced and shown to qualitatively capture the observed features. The double quintuple-layer materials display notably worse thermoelectric properties, since their dispersions are significantly modified compared to the single quintuple-layer case. The benefits of ring-shaped bands are sensitive to the alignment of the two ring maxima and to the degree of ring anisotropy. Overall, single quintuple-layer Bi$_2$Te$_3$ and Bi$_2$Se$_3$ are most promising, with the DOS scattering model giving the highest power factors.

description: EU agriculture and arable crops in particular are suffering from competitiveness deficits compared to other producers in the world economy. One potential strategy to cope with competitiveness challenges is to focus on research and technological innovation. The objective of this paper is to present the results of the project EUROCROP (Agricultural research for improving arable crop competitiveness – EUROCROP - http://www.eurocrop.cetiom.fr/), aimed at the identification of research priorities for arable crop competitiveness. The project adopts a definition of competitiveness based on a combination of economic competitiveness and social/environmental sustainability. Furthermore, the project utilises both a crop chain and a horizontal issue perspective, and develops research priorities through the interaction of the scientific level (expert group approach) and the stakeholder level (scenario analysis). The main result of the project is the elaboration of approximately eighty research topics. Among these, the main areas for research identified are A: Risk management and adaptation of arable farming; B: Innovation in cropping systems for high environmental and economic performances; C: Limiting the impact of arable crop cropping systems on green-house gas emissions; D: Better understanding of public concern about arable crop production and products and communication with global and local societies. The project confirms that a number of well established research topics retain their importance (e.g. yield improvement, plant protection). However, they require cautious coordination with an increasingly complex system of short term priorities.

(Fig. 19)
Material examined. 1 ♀, 3 ♂♂ (MNHN-IU-2018- 1772) from Ascidia obliqua Alder, 1863, middle of fjord, Kristineberg, Sweden; 1 ♀ (dissected and figured) from A. obliqua, Norway, Norbi Stn CP11, depth 300 m.
Diagnostic characters of female. Body (Fig. 19A) of dissected specimen 3.0 mm long. Caudal ramus (Fig. 19B) rectangular, about 3.6 times longer than wide (193×53 μm) and 1.4 timeslongerthan anal somite, setulose along outer margin; outer lateral seta positioned at 75% of ramus length.
Rostrum (Fig. 19C) tapering, about 1.5 times as long as wide, minutely bifurcate at apex. Antennule 15- segmented. Antenna (Fig. 19D) with 2 equally large setae on basis representing exopod; compound distal endopodal segment slender, about 5 times as long as wide; terminal claw small, about 1/3 aslongas segment.
Mandible (Fig. 19E) with patch of fine spinules proximally on outer surface of basis; endopod armed with 3 and 9 setae on first and second segments, respectively. Maxillule (Fig. 19F) with 10 setae on precoxal arthrite; endopod distinctly 2-segmented with 1 and 4 setae on first and second segments, respectively; 3 of distal setae on second endopodal segment naked. Maxilla (Fig. 19G) 5- segmented; syncoxalarmature elements 4, 1, 2, and 3 setae on first to fourth endites, basis with claw plus 2 setae, and with 1, 1, and 3 setae on first to third endopodal segments. Maxilliped (Fig. 19H) 3-segmented and armedwith 10, 1, and 3 setae on first to third segments, respectively.
Leg 1 basis with short inner distal spine less than half as long as first endopodal segment; exopod distinctly shorter than endopod; first exopodal segment with several spinules on outer margin; first endopodal segment about 1.6 times longerthan wide. Spines on outer margin of exopods of legs 2–4 slender, smooth, and straight.
Leg 5 (Fig. 19I) protopod distinctly articulated from ventral surface of pedigerous somite, ornamented with 4 or 5 spinules on inner distal margin, outer distal process slightly shorter than exopod and tipped with pinnate seta; free exopodal segment bulbous, narrowed proximally, about 1.7 times longerthan wide (61×37 μm), with convex outer margin and almost straight inner margin bearing 6 or 7 spinules; distal armature comprising inner spine and outer seta about as long as segment
Remarks. The characteristic shape of the free exopodal segment of leg 5 in the female allows this species to be easily identified. This species has a distribution ranging from Scandinavia in the North to the Mediterranean (Illg, 1958).

description: Significant discrepancies have been observed between proton form factors as measured by Rosenbluth separation and polarization transfer techniques. There are indications that this difference may be caused by corrections to the one photon exchange approximation that are not taken into account in standard radiative correction procedures. In this paper, we constrain the two-photon amplitudes by combining data from Rosenbluth, polarization transfer, and positron-proton scattering measurements. This allows a rough extraction of these two-photon effects in elastic electron-proton scattering, and provides an improved extraction of the proton electromagnetic form factors.

description: The Cretan tourism sector has been characterised by a large and rapid growth from 1970 to 2000 and has gone on the primary industry of the island. Despite the fact that this growth has seemed stagnant over the last few years, tourism is still of vital importance for the local economy. Agricultural industries are strongly linked with tourism activities and usually derive numerous benefits from them. Understanding tourists’ opinions and demands plays a crucial role in implementing appropriate and sustainable future agricultural offer strategies on the island in the future. As several studies have previously indicated, the current global economic and financial crisis has deeply cut household expenditure and 2009 has been predicted to be a difficult year for the tourism industry. This research was carried out in the western prefecture of Crete, Chania, which is characterised by its high number of mass-tourism infrastructures located in the northern coast and by its mountainous rural areas delaying development in the inland and in the southern part of the prefecture. The aim of this work is first, on the basis of data on tourists’ attitudes and preferences compiled in a specific face-to-face survey conducted in August 2009, to report on the profile of the tourists that have spent their holidays in Crete; then, regarding their local product consumption and preferences, to understand the way tourism has helped Cretan agricultural demand and try to make the future management of the sector easier. Finally, an exploratory study on the short-term economic crisis effects will be undertaken by the authors in order to uncover changes in the nature of tourists’ spending patterns and trends.

description: Joint management for the purpose of meeting common needs has been the concept of cooperativeness for over 100 years. In Poland, it developed in various sectors of the economy, with uneven intensity. It appeared in the food production sectors, in particular in the dairy industry, at quite an early stage. After World War II, due to inclusion of Poland into the block of socialist states, the concept of cooperativeness was strongly perverted, as it was identified with the process of collectivization of agriculture, and only political prerequisites laid the foundations for such a process. Only after year 1989 possibilities of giving the proper role to the concept of cooperativeness appeared. Currently, this role is reinforced along with the growing care for protection of the producer, consumer and the environment. The aim of the article is to determine the current place of cooperativeness in the Polish food production system as well as to indicate the new conditions reinforcing its role. The study adopts a foundation that cooperativeness is the form of conducting business operations, which allows reconciling often contrary interests of the producer, consumer and the environment in an ever more competitive and global world.

description: Do retailers exert market power in the fresh fruit and vegetables markets? In the EU countries, as the retail industry distributes a significant part of fruit and vegetables, a non competitive behavior might have significant impact on consumption, on surplus and welfare. In this paper, we shed some light on the degree of non-competitive distortions in the French fresh fruit and vegetable markets. We analyze the market of tomato. The analysis is based on aggregate data on final consumption and prices at both shipper and consumer levels in France. The structural model is composed of a system of demand equations, supply equations and pricing equations which include terms that capture the oligopoly and oligopsony power of the retail sector and that account for product differentiation. We show that: i) elasticity of demand varies during the year ii) the exercise of market power decreases over time iii) if markets were competitive, retail price would decrease by about 2% to 12% depending on the year while shipping price might be 10% to 54% higher than observed. As a general result quantities consumed would not change significantly. We conclude that the retail sector exerts a moderate market power.
Academic Nomads. The Changing Conception of Academic Work under Precarious Conditions

description: In addition to the economic destabilization of academic labour markets in neoliberal times, intellectual labour also experiences ideologically motivated repressions in a number of countries. One of the most recent examples of the latter has been the AKP government’s attack on dissident scholars, which started following the Academics for Peace Petition in January 2016 and escalated in the aftermath of the alleged coup attempt in July 2016. As a result, over the course of the past two years, a growing number of the signatories of the Peace Petition have been forced to leave Turkey to escape imprisonment and/or unemployment. In most cases, the emigrated academics are offered short-term scholarships contingent upon political risk factor which help them avoid immediate threats from the Turkish government for the time being. However, without a future prospect for a steady position and/or a settled life on the horizon, they are faced with the existential precariousness of a forced nomadic way of living. Against the backdrop of the occupational dismantling and geographic uprooting that the exiled Peace Academics are experiencing, this study seeks to explore the challenges but also the possibilities that this severe precarity bears for a new form of intellectual subjectivity. The main question of this paper is how the confrontation with existential insecurity transforms the way the academics perceive their profession and whether this experience might lead to a wider questioning of the institutional academia in general. For this purpose, it attempts to map out the shared expressions of insecurity, disillusionment, and hope, drawing on in-depth interviews with the signatories of Academics for Peace Petition in German exile.
