Inclusion or Exclusion? Trade union strategies and Labor migration

Inclusion or Exclusion? Trade Union Strategies and Labor Migration This research identified and analyzed immigration-related strategies of the Finnish Construction Trade Union (FCTU) and the Service Union United (SUU); e.g. how the unions react to labor immigration, whether unions seek to include migrants in the unions, and what is migrants’ position in the unions. The two unions were chosen as the focus of the research because the workforce in the sectors they represent is migrant-dense. The study also analyzed the experiences that migrants who work in these sectors have with trade unions. The Estonian labor market situation –including the role of Estonian trade unions– was also examined as it has a considerable impact on the operating environment of the FCTU. The results of the study indicate that immigration is a contradictory issue for both unions. On the one hand, they strive to include migrants as trade union members and to defend migrants’ labor rights. On the other hand, they, together with their umbrella organization the Central Organisation of Finnish Trade Unions (SAK), seek to prevent labor immigration from outside the EU and EEA countries. They actively defend current labor immigration restrictions by drawing atten- tion to high unemployment figures and to the breaches of working conditions migrants encounter. In contrast, the employer organizations promote a more liberal state policy on labor immigration because they see it as a boost for business. Both the unions and the employer organizations ground their arguments on national interest. However, the position of the trade union movement is not uniform: unions belonging to the Confederation of Unions for Professionals and Managerial Staff in Finland (Akava) embrace more liberal labor immigration stances than the SAK. A key trade union strategy is to try to guarantee that migrants’ working condi- tions do not differ from those of the natives. The FCTU and the SUU inform migrants about Finnish collective agreements and trade union membership in the most common migrant languages. This is important for the unions because it is not in their interest that migrants’ working conditions are undercut. The interviewed migrants said that natives had more negotiating power with employers, which is often negatively portrayed in migrants’ working conditions. Migrants perceive that trade unions have an important role in protecting their working conditions. However, they stressed that migrants’ knowledge of unions is often very limited. The number of migrants in both two unions studied here is increasing. Espe- cially in the SUU, a considerable proportion of the new members are migrants. The FCTU is in a more challenging situation than the SUU because migrant construc- tion workers often work only for short periods in Finland and are consequently not interested in becoming union members. The unions’ strategies partly differ: the FCTU was the first Finnish trade union to establish a trade union branch/lo- cal for migrant members. The goal is to facilitate migrants’ inclusion in the union and to highlight the specific problems they face. The SUU, for its part, insists that such a special strategy would exclude migrants within the union organization. Despite the unions’ strategies, migrants are still underrepresented as union members and officials, which some of the interviewed migrants saw as a problem. Immigrants’ perception of trade unions was pragmatic: they had joined unions when membership yielded concrete benefits. In spite of the unions’ strategies, migrants –and temporary migrants– encoun- ter specific problems in terms of working conditions. Both unions demand more state intervention to protect migrants’ labor rights because overseeing working conditions consumes union resources. However, without the unions’ intervention, these problems would be more common than is currently the case. For instance, some of the interviewed migrants had received trade union assistance in claim- ing unpaid wages. The study demonstrated with the help of building on Walter Korpi’s power resources theory, that immigration is a power resource issue for the unions: suc- cessful immigration-related strategies strengthen unions –and vice versa. The research also showed how the unions’ operating environments constrain and enable their immigration-related strategies. This study has illuminated a previously ignored dimension: the immigrant- inclusive strategies of the Finnish trade unions. The research material consists of 78 qualitative interviews, observation in trade union events, and trade unions’ and employer organizations’ public state- ments.

Germinação de sementes de calabura (Muntingia calabura L.)

O trabalho teve como objetivo, avaliar a influência da luz, da temperatura do substrato e do pré-tratamento mais eficiente para a germinação de sementes de Muntingia calabura L. As sementes foram semeadas em diferentes substratos: sobre papel, entre papel, sobre areia, entre areia, sobre mistura de terra + areia + esterco, entre mistura terra + areia + esterco, sobre mistura terra + areia + vermiculita e sobre vermiculita, incubadas nas temperaturas constantes de 20, 25 e 30ºC e alternada de 20-30ºC. Como tratamentos pré-germinativos foram estudados o efeito da cal virgem (CaO) e do nitrato de potássio (KNO3) na germinação das sementes com mucilagem. O delineamento experimental utilizado foi inteiramente casualizado com quatro repetições de 25 sementes e as análises estatísticas foram efetuadas em esquema fatorial. A protrusão da raiz primária e a emissão do primeiro par de folhas foram adotados como critério para considerar a semente germinada. A germinação foi avaliada diariamente, determinando-se a porcentagem e a velocidade de germinação. Foi verificada interação significativa entre os fatores substrato e temperatura. Os melhores substratos foram sobre areia e entre papel, na temperatura alternada de 20-30ºC, com 99 e 100% de germinação, respectivamente. Os pré-tratamentos CaO e KNO3 melhoram a capacidade germinativa das sementes com mucilagem.

Hinnoittelustrategian valinta terästeollisuudessa - Case Teräsyhtiö Oy

Kandidaatin tutkielma ”Hinnoittelustrategian valinta terästeollisuudessa – Case Teräsyhtiö Oy” käsittelee tuotantohyödykkeitä valmistavan hiiliteräsyhtiön hinnoittelustrategian valintaa, peilaamalla toteutuvaa hinnoittelua hinnoittelun teoreettisiin periaatteisiin. Tutkimuksen tavoitteeksi kohdentui selvittää, kuinka hyvin kohdeyrityksen hinnoittelu noudattaa hinnoittelun teoreettisia periaatteita. Tavoitteena oli myös selvittää, miten hinnoittelu toteutuu kohdeyrityksessä ja mitkä tekijät vaikuttavat tähän strategiseen päätökseen. Tutkielman teoriaosuuden muodostaa hinnan ja hinnoitteluprosessin teorian muodostama kokonaisuus yhdessä tutkielman varsinaisen viitekehyksen kanssa, jona toimivat kustannusperusteisen ja markkinalähtöisen hinnoittelun perinteiset mallit. Tutkielmassa markkinalähtöisillä malleilla viitataan kysyntä- ja kilpailulähtöisiin malleihin. Tutkimuksen aineisto kerättiin teema-haastattelun avulla, haastattelemalla kolmea Case-yrityksen hinnoittelussa toimivaa henkilöä. Tutkimus toteutui laadullisena tutkimuksena hyödyntäen analyysissä teorialähtöistä sisällönanalyysiä. Tutkimustulosten osalta tärkeään rooliin asettui kahtiajako kotimarkkinoihin ja kotimarkkinoiden ulkopuolisiin alueisiin. Nämä alueet määrittivät pitkälle sitä, jouduttiinko hinnoittelu toteuttamaan hintaa seuraten vai asettaen. Toimialan alueellisten hintatasojen osalta merkittävässä asemassa olivat teräsyhtiöiden avoimet hintalistat, jotka ohjaavat hinnoittelua vahvasti. Hinnoitteluprosessin osalta tärkeimmäksi tavoitteeksi asettui kannattavuuden takaaminen, sekä johdonmukaisen hinnoittelun harjoittaminen. Markkinalähtöistä hinnoittelua ohjaavista ulkoisista tekijöistä tärkeintä oli Kilpailulain (948/2011) huomioiminen. Asiakkaan rooli hinnoittelussa oli myös erittäin merkittävä. Tutkimus osoitti kohdeyrityksen hinnoittelun painottavan markkinalähtöisiä menetelmiä, huomioiden kuitenkin kustannusten vaikutus katteen kautta. Tutkimus osoitti myös, ettei asiakkaan kokemaa arvoa huomioida hinnoittelun pohjatyössä siinä määrin, kuin olisi mahdollisesti tarpeellista. Tutkimuksen johtopäätöksissä korostuu se, kuinka asiakasarvon huomioiminen voisi mahdollistaa yritykselle korkeamman tuloksellisuuden.

The kinetics and induced decomposition on the thermal decomposition of hydroperoxides /

This project is focussed on the thermsLl decomposition of t-butyl hydroperoxide and sec-butyl hydroperoxide at 120°C to 160°C in three alcohol solvents. These are methanol, ethajiol and isopropyl alcohol. The aim of the project was to examine the process of induced decomposition. Thermal decomposition of t-hutyl hydroperoxide and sec-butyl hydroperoxide indicate that these reactions have first-order kinetics with activation energies on the order of 20 to 28 K cal/mole, Styrene was used as a free radical trap to inhibit the induced decomposition. The results permitted calculation of how much induced decomposition occurred in its absence. The experimental resvilts indicate that the induced decomposition is important for t-butyl hydroperoxide in alcohol solvents, as shown by both the reaction rate suid product studies. But sec-butyl hydroperoxide results show that the concerted mechanism for the interaction of two sec-butylperoxy radicals occurs in addition to the induced decomposition. Di-sodium E.D,T.A. was added to reduce possible effects of trace transition metal ion .impurities. The result of this experiment were not as expected. The rate of hydroperoxide decomposition was about the same but was zero-order in hydroperoxide concentration.

A Study of role conflict, role ambiguity, locus of control, job satisfaction and participation in decision making among front-line vocational service workers for mentally retarded adults

This study was an investigation of individual and organizational factors, as perceived by front-line vocational service workers from Adult Rehabilitation Centres (ARC Industries) for mentally retarded adults. The specific variables which were measured included role conflict/role ambiguity (role factors), internal/external locus of control (individual differences), job satisfaction with work and supervision (job attitudes) and participation in deci~ion making (organizational factor). The exploration of these constructs was conducted by means of self-report questionnaires which were completed by sixty-nine out of a total of ninety front-line employees. The surveys were distributed in booklet form to nine distinct rehabilitation facilities from St. Catharines, West Lincoln, Greater Niagara, Port Colborne, WeIland, Fort Erie, Hamilton, Guelph and Brantford. The survey data was evaluated by the statisti.cal Package for the Social Sciences (SPSS) which used the Pearson Product Moment Correlation procedure and a compar~son of means test. A comparison of correlation coefficients test was also conducted. This statistical procedure was calculated mathematically. The results obtained from the statistical evaluation confirmed the prediction that self-reported measures of participation in decision making and satisfaction (work and supervision) would be negatively correlated with role conflict and role ambiguity. As well, the speculation that perceived satisfaction (work and supervision) would be positively correlated with participation in decision making was empirically supported. Internal and external locus of control did not contribute to a significant difference in r~sponses to role perceptions (conflict and ambiguity) , satisfaction (work and supervision) or the correlational relationship between participation in decision making and satisfaction (work and supervision). Overall, the findings from this study substantiated the importance of examining employee perceptions in the workplace and the interrelationships among individual and organizational variables. This research was considered a contribution to the general area of occupational stress and to the study of individuals in work organizations.

Commodities and their fetishism

Many pr oblems present themselves in at tempting t o discuss Marx's noti on of the fetish characteristics of commodities. It has been argued that it is one of the central points of Marx's en tir e c or pus. 1 It has also been argued that it i s merely "a brilli an t s oci olog i cal genera lization l ! and, even furth er, that it is an Hi ndependent and separate entity, internally hardly related t o Marx's economic theory" .2 How could such a theory be understo od i n such drastically diff erent ways? Perhaps the clue is to be f ound somewhere in Marx' s discussion of the fetishism of commodities itself. Because of the difficulty in un derstanding fetishism , I intend t o examine what Marx himself has t o say first befor e dealing with any points related to the notion of fetishism. Thus , the first parts of this thesis will c onsist of l ong qu otations and repetition of what Marx has t o say. If a noti on may be called ' central' and yet 'hardly related' t o Marx's wor k at the same time, surely a clear examination of this section is necess ary. Aft er an examination of the initial secti ons of Cae ital ] I intend t G examine the f ollowing : the r e lation of fetishism t o the t he ory of alienati on; how one may regard f etishism as a pr oblem f or philosophy; and how, in f act, the theory of fetishism is of prime imp ortance f or an understan ding of Marx's wr itings. What I want to stress throughout is that with o u~ an understanding of what is inherent in the pr oduction of the commodity causing i t t o be necessarily fetishistic, it is practically imp ossible t o understand much of Marx's other writin gs. A commodity appears, at fir st sight, a very trivial thing and easi ly un derst ood. Itsanalysis shows that it i s , in r eality , a very queer thing , abo unding in ~taphysical s ubtleties and theological nic eties .

Differentiation of morphology and reproductive traits in the house finch (Carpodacus mexicanus): a comparison between native and introduced populations

House Finches (CarpQdacqs mexiCAnuS) were introduced to Long Island, New York from southern'California in 1940. Apparently, an initial sample of less than 100 birds has given rise to a population that now occupies much of the eastern United States. This study was to determine if morphological and reproductive changes have taken place in introduced eastern birds, which have colonized a novel environment. A study area in Goleta, California (CAL) represented the parental population whereas for comparison, House Finches in St. Catharines, Ontario (ONT) represented the introduced population. Interlocality variation in 25 morphometric characters of 100 adult House Finches was examined statistically. Singleclassification analysis of variance revealed significant interlocality differentiation in seven characters of males and nine of females. Females showed differentiation in more limb elements than males. Analysis of character variation using discriminant and principal component analysis distinguished samples on the basis of variation in shape. Compared to CAL, aNT birds (especially females) had smaller extremities relative to certain core parts and weight. Females showed similar patterns of character covariation in each locality on the second principal component, which suggests that differentiation of the ONT population may not be solely environmentally induced. Sexual dimorphism was evident in four charaoters in aNT and five in CAL. Disoriminant analysis distinguished sex on the basis of variation in shape. Males possessed a relatively larger flying apparatus and small.er hind limbs than females. The dearee of sexual dimorphism did not vary sicnifioantly between looalities. 3 Data on reproduotive parameters were oolleoted in 1983 and 1984 in ONT, and 1984 in CAL. In 1984, Bouse Finohes began breedina approximately three months earlier in CAL than in ONT. In ONT, there was no sianifioant differenoe in mean olutoh initiation date between 1983 and 1984. In both looalities most nests oontained either four or five ea",s, and olutoh size differenoes between looalites were not signifioant. Seasonal deolines in olutch size were evident in ONT but not in CAL. Intralooality variation in e.g weight and size was not related to clutch size. E",g weiaht showed no seasonal trend in ONT, but inoreased sianifioantly with breed ina season in OAL. In both looalities e8'''' weiaht increased sipifioantly with order of layina in olutohes of four but not in clutohes of five. Eag's in ONT in 1983 and 1984 were sip.ificantly larser than in CAL in 1984. The modal inoubation period was 13 days and did not vary sip.ifioantly between localites. In both looalities nestling weiaht on the day of hatohing was oorrelated to fresh ega welaht. For muoh of the period between hatohing and 14 days post-hatoh, ONT nestlinas were signifioantly laraer than CAL nestlings in terms of weiaht. bill length, bill depth, and manus length.

Paragenetic history of the Ordovician Trenton Group carbonates, Southwestern Ontario

Geochemical examination of the rock matrix and cements from core material extracted from four oil wells within southwestern Ontario suggest various stages of diagenetic alteration and preservation of the Trenton Group carbonates. The geochemical compositions of Middle Ordovician (LMC) brachiopods reflect the physicochemical water conditions of the ambient depositional environment. The sediments appear to have been altered in the presence of mixed waters during burial in a relatively open diagenetic microenvironment. Conodont CAl determination suggests that the maturation levels of the Trenton Group carbonates are low and proceeded at temperatures of about 30 - 50°C within the shallow burial environment. The Trenton Group carbonates are characterized by two distinct stages of dolomitization which proceeded at elevated temperatures. Preexisting fracture patterns, and block faulting controlled the initial dolomitization of the precursor carbonate matrix. Dolomitization progressed In the presence of warm fluids (60 75°C) with physicochemical conditions characteristic of a progressively depleted basinal water. The matrix is mostly Idiotopic-S and Idiotopic-E dolomite, with Xenotopic-A dolomite dominating the matrix where fractures occur. The second stage of dolomitization involved hydrothermal basinal fluid(s) with temperatures of about 60 - 70°C. These are the postulated source for the saddle dolomite and blocky calcite cements occurring in pore space and fractures. Rock porosity was partly occluded by Idiotopic-E type dolomite. Late stage saddle dolomite, calcite, anhydrite, pyrite, marcasite and minor sphalerite and celestite cements effectively fill any remaining porosity within specific horizons. Based on cathode luminescence, precipitation of the different diagenetic phases probably proceeded in open diagenetic systems from chemically homogeneous fluids. Ultraviolet fluorescence of 11 the matrix and cements demonstrated that hydrocarbons were present during the earliest formation of saddle dolomite. Oxygen isotope values of -7.6 to -8.5 %0 (PDB), and carbon isotope values of - 0.5 and -3.0 %0 (PDB) from the latest stage dog-tooth calcite cement suggest that meteoric water was introduced into the system during their formation. This is estimated to have occurred at temperatures of about 25 - 40°C. Specific facies associations within the Trenton Group carbonates exhibit good hydrocarbon generating potential based on organic carbon preservation (1-3.5%). Thermal maturation and Lopatin burial-history evaluations suggest that hydrocarbons were generated within the Trenton Group carbonates some time after 300 Ma . Progressively depleted vanadium trends measured from hydrocarbon samples within southwestern Ontario suggests its potential use as a hydrocarbon migration indicator on local (within an oilfield) and on regional scales.

L’histoire postglaciaire de la végétation et des feux dans la région du Lac Mégantic

La région du lac Mégantic est probablement la première zone à s'être déglacée au Québec, ce qui lui confère un intérêt particulier. L'analyse pollinique et anthracologique des sédiments des trois lacs situés à ses abords, soit les lacs Clinton, Dubuc et des Joncs ont permis de reconstituer l'histoire locale et régionale de la végétation et des feux. La présence d'un gradient altitudinal a entrainé des décalages surtout dans l'instauration des premières phases forestières. La région s'est déglacée vers 13 500 ans AA, et une toundra s'y est installée. Le début de l'afforestation est marqué par l'arrivée du sapin baumier et de l'épinette noire. Par la multiplication de leurs populations, la forêt s'est fermée vers 10 000 ans AA pour constituer une forêt boréale qui fût alors perturbée par plusieurs épisodes de feux. Vers 8000 ans AA, les nouvelles conditions climatiques favorisent les espèces feuillues et instaurent une érablière à bouleau jaune et une diminution de la fréquence des feux. Les résultats obtenus permettent d'enrichir les connaissances paléophytogéographiques et anthracologiques du Québec.
