The literature on Finnish immigrant working-class movements in North America frequently makes reference to the phenomenon of "hall socialism," so-called because of the central position that the socialist or labor hall occupied in the political, associational, and cultural life of many Finnish communities throughout the twentieth-century. In the 1930s, over 80 such Finnish halls were spread across Canada, and many people associated with these halls vigorously supported the mission of organized labor. This paper will examine the history, ideas, and practices of the Industrial Workers of the World-influenced Canadan Teollisuusunionistien Kannatus Liitto (CTKL; Canadian Industrial Unionist Support League), and its connections to Finnish Canadian hall socialism. The paper will consider the role of the CTKL in supporting workers' struggles, the significance of the hall as a part of the infrastructural bedrock that sustained this support, and the broader interaction between social and radical organizing commitments.

Following the recent UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions, the first wave of scholarly work has focused on clarifying the interface between the Convention and the WTO Agreements. Building upon these analyses, the present article takes however a different stance. It seeks a new, rather pragmatic definition of the relationship between trade and culture and argues that such a re-definition is particularly needed in the digital networked environment that has modified the ways markets for cultural content function and the ways in which cultural content is created, distributed and accessed. The article explores first the significance of the UNESCO Convention (or the lack thereof) and subsequently outlines a variety of ways in which the WTO framework can be improved in a ‘neutral’, not necessarily culturally motivated, manner to become more conducive to the pursuit of cultural diversity and taking into account the changed reality of digital media. The article also looks at other facets of the profoundly fragmented culture-related regulatory framework and underscores the critical importance of intellectual property rights and of other domains that appear at first sight peripheral to the trade and culture discussion, such as access to infrastructure, interoperability or net neutrality. It is argued that a number of feasible solutions exist beyond the politically charged confrontation of trade versus culture and that the new digital media landscape may require a readjustment of the priorities and the tools for the achievement of the widely accepted objective of cultural diversity.

While a remarkable continuity in smallholder agricultural production has been identified, the shift from subsistence orientation towards more wage dependence appears in a different light when analysed under a gender perspective. "Feminisation" has been a catchphrase to characterise some of these processes; however, the debate has been subject to overgeneralisation, and can only inadequately grasp the gender dynamics in what has been referred to as "new ruralities". Illustrated for high-value crop production as an expression of agricultural transition in the Global South, this contribution offers a critical account of the feminisation thesis. Instead of discarding the notion of feminisation, it advocates a reassessment of its potential as a comprehensive framework against which empirical findings can be reflected. While conventional uses of the feminisation thesis have, in their great majority, come up with the conclusion that for women it can always only get worse, I propose a perspective which reveals gains and risks and how they are shared between men and women as they engage in new agricultural labour markets. This perspective rests on a methodology for case-based, comparative studies developed in this paper as a contribution for assessing the nature of agricultural transition and to investigate the qualitative change associated with new ruralities. A distinctive appreciation of the substance of agricultural change for different members of the rural society – namely men and women, but also different men, and different women – is the premise for overcoming barriers to shared development, and for framing effective governance in the context of global development.

The odor produced by a plant under herbivore attack is often used by parasitic wasps to locate hosts. Any type of surface damage commonly causes plant leaves to release so-called green leaf volatiles, whereas blends of inducible compounds are more specific for herbivore attack and can vary considerably among plant genotypes. We compared the responses of naïve and experienced parasitoids of the species Cotesia marginiventris and Microplitis rufiventris to volatiles from maize leaves with fresh damage (mainly green leaf volatiles) vs. old damage (mainly terpenoids) in a six-arm olfactometer. These braconid wasps are both solitary endoparasitoids of lepidopteran larvae, but differ in geographical origin and host range. In choice experiments with odor blends from maize plants with fresh damage vs. blends from plants with old damage, inexperienced C. marginiventris showed a preference for the volatiles from freshly damaged leaves. No such preference was observed for inexperienced M. rufiventris. After an oviposition experience in hosts feeding on maize plants, C. marginiventris females were more attracted by a mixture of volatiles from fresh and old damage. Apparently, C. marginiventris has an innate preference for the odor of freshly damaged leaves, and this preference shifts in favor of a blend containing a mixture of green leaf volatiles plus terpenoids, after experiencing the latter blend in association with hosts. M. rufiventris responded poorly after experience and preferred fresh damage odors. Possibly, after associative learning, this species uses cues that are more directly related with the host presence, such as volatiles from host feces, which were not present in the odor sources offered in the olfactometer. The results demonstrate the complexity of the use of plant volatiles by parasitoids and show that different parasitoid species have evolved different strategies to exploit these signals.

OBJECTIVE The aim of this study was to elucidate the relationship between the echogenicity of carotid artery plaques and the following risk factors: circulating oxLDL, hsCRP, the metabolic syndrome (MetS), and several of the traditional cardiovascular (CV) risk factors. MATERIAL AND METHODS A cross-sectional population-based study of 513 sixty-one-year-old men. The levels of circulating oxLDL were determined in plasma samples by sandwich ELISA utilizing a specific murine monoclonal antibody (mAb-4E6). High-sensitivity CRP was measured in plasma by ELISA. Plaque occurrence, size and echogenicity were evaluated from B-mode ultrasound registrations in the carotid arteries. Plaque echogenicity was assessed based on a four-graded classification scale. RESULTS A higher frequency of echolucent carotid plaques was observed with increasing levels of oxLDL and systolic blood pressure (p = 0.008 and p = 0.041, respectively). Subjects with the MetS had a significantly higher frequency of echogenic plaques than subjects without the MetS (p = 0.009). In a multiple logistic regression analysis, oxLDL turned out to be independently associated with echolucent carotid plaques. CONCLUSIONS The occurrence of echolucent carotid plaques was associated with oxLDL and systolic blood pressure, and oxLDL was associated with echolucent carotid plaques independently of systolic blood pressure.

OBJECTIVES The aim of the study was to test the hypothesis that circulating markers of inflammation (high-sensitive C-reactive protein, hsCRP) and oxidative modification of lipids (oxidized low-density lipoprotein, oxLDL) were associated with the occurrence of echolucent rather than echogenic femoral artery plaques in a cross-sectional population based cohort of 513, 61-year-old men. BACKGROUND The relationships between circulating oxLDL, hsCRP and the occurrence of echolucent plaques in the femoral artery have not previously been investigated. METHODS The levels of circulating oxLDL and hsCRP were determined in plasma by ELISA. Plaque occurrence, size and echogenicity were measured by B-mode ultrasound in the right femoral artery. Assessment of plaque echogenicity was based on the classification (grades 1-4) proposed by Gray-Weale et al. RESULTS A higher frequency of echolucent femoral plaques was observed in subjects with the metabolic syndrome and current smokers (p=0.01 and p<0.001, respectively) as well as with increasing levels of oxLDL and hsCRP (p=0.002 and p=0.005, respectively). In a multiple logistic regression analysis oxLDL and current smokers turned out to be independent associated with the presence of echolucent femoral artery plaques. CONCLUSIONS The results of the present study support our hypothesis that circulating oxLDL is a marker of an unstable echolucent plaque phenotype in the femoral artery in man.

Objective. Although those age 75 and older are the fastest growing age group in the U.S., few studies focus on the course and treatment of depression in this age group. This study examines the differences between the young-old (age 60 to 74) and the old-old (age 75 and older) in regards to their response to a collaborative care model for depression in primary care. We hypothesized that old-old participants would have more severe depression and have a lower rate of treatment response compared to young-old participants. ^ Methods. The sample consisted of 906 participants (n = 606 young-old; n = 300 old-old) who were randomized to receive the intervention with a depression care manager in the IMPACT trial. This study compared young-old and old-old patients on process of care and outcome variables to identify potential differences between the two age groups. Process of care was determined by the type of treatment and level of stepped care received. Clinical outcomes included SCL-20 depression scores, treatment response (defined as a ≥50% decrease in SCL-20 score from baseline) and complete remission (defined as a SCL-20 score <0.5) at 3-, 6-, and 12-months follow-up. ^ Results. The process of care variables did not differ between the two age groups. SCL-20 depression scores did not significantly differ between the two age groups at all follow-up intervals. Treatment response was significantly different between young-old and old-old participants at 6- and 12-months. Complete remission rates were significantly different between the two age-groups at 12-months follow-up. ^ Conclusions. Young-old and old-old patients have a similar clinical response to initial collaborative depression care in a primary care setting, but old-old patients may have lower rates long-term treatment response and complete remission. These findings will help guide future clinical and public health approaches to treat old-old patients with depression. ^
