The Dark Side of International Business? Stakeholder Approach to Human Trafficking in Finnish Construction and Service Sectors

Human trafficking is not a new phenomenon. It has existed in various forms for ages around the world. Some researchers have even compared it to slavery, calling it the modern form of slavery in the 21st century. This study is particularly interested in the role of work-related human trafficking in Finnish business. In order for something to be called work-related human trafficking, the concepts of forced labour and human trafficking have to overlap. From the economic point of view, human trafficking is governed by the laws of supply and demand. In many countries the global pressure on cutting costs has created two trends: the increased supply of migrant workers and the deregulation of labour markets. These competitive pressures can have an adverse impact on the conditions of employment and, in the worst cases, can lead to forced labour and trafficking. In fact, trafficking has become one of the most profitable illicit industries worldwide, generating tremendous profits due to its low costs and huge profits. Therefore, it is important to investigate the phenomenon from the business point of view. This study is a qualitative research conducted by using theme interviews as a research approach. Altogether 13 interviews have been conducted and some secondary data has been used in order to find out what the role of human trafficking is in Finnish business. The special sectors investigated are the Finnish construction and service sectors. The theory framework used in this study follows the stakeholder approach. The relevant stakeholder groups for this study are: ‘institutions and authorities’, ‘law enforcement’, ‘management’ and ‘employees – potential victims’ of trafficking. With the help of these stakeholder groups, a holistic picture of the phenomenon is formed. It can be concluded that the role of human trafficking is complicated but it does exist in Finnish business. It appears in low-cost business sectors where the demand for cheap labour is high. Thus, often the victims are foreigners who do not know the culture or the Finnish conditions of employment. Especially smaller Finnish companies are at risk of getting involved in human trafficking or related exploitation cases since monitoring is much more scarce in these firms than in larger companies. The risk of human trafficking and exploitation is also higher at the bottom of the complicated subcontracting chains or when using foreign recruitment agencies. Thus, the study believes that active and intensive collaboration between the company’s different stakeholder groups is needed in order to prevent work-related human trafficking from flourishing in Finland.

A Study of African American Vernacular English in Three Novels and Colloquial Finnish in their Translations – The Dark Tower II: The Drawing of the Three, A Time to Kill and Push

Pro gradu -tutkielma käsittelee afroamerikkalaisen puhekielen (African American Vernacular English, AAVE) käyttöä kolmen englanninkielisen romaanin dialogissa ja suomen yleispuhekielen käyttöä romaanien käännöksissä. Tutkimus on pääasiassa kvantitatiivinen ja deskriptiivinen. Romaanit ovat Stephen Kingin The Dark Tower II: The Drawing of the Three (1987) (Musta torni 2, Kolme korttia pakasta 2005, suom. Kari Salminen), John Grishamin A Time to Kill (1989) (On aika tappaa 1994, suom. Kimmo Linkama) ja Sapphiren Push (1996) (Precious – harlemilaistytön tarina 2010, suom. Kristiina Drews). Alkukielisten romaanien osalta Grisham ja Sapphire suosivat lauseopillisia kielenpiirteitä, kun taas King on suosinut äänteellisiä. Sen sijaan käännöksissä piirteistä yleisimpiä ovat äänteelliset ja harvinaisimpia lauseopilliset. Vaikka käännöksissä sanastolliset piirteet ovat taajaan esiintyviä, äänteellisiä piirteitä esiintyy niitä enemmän. Poikkeuksena on On aika tappaa, jossa sanastollisia piirteitä esiintyy enemmän kuin äänteellisiä. Tulos eroaa Sampo Nevalaisen vuonna 2003 tekemästä tutkimuksesta, jossa hän sai selville, että käännöksissä käytetyt piirteet olivat enimmäkseen sanastollisia, kun taas alun perin suomeksi kirjoitetussa kaunokirjallisuudessa puhekielisyyden vaikutelma saatiin aikaan pääasiassa äänteellisin keinoin. Mahdollinen selitys tässä tutkimuksessa havaitulle erolle on se, että kahdessa romaanissa esiintyvä leimallinen AAVEn käyttö on saanut kääntäjät käyttämään samanlaisia strategioita kuin suomalaiset kirjailijat murretta kirjoittaessaan.

Ring Dark Solitons in Toroidal Bose-Einstein Condensates

In this Thesis, we study various aspects of ring dark solitons (RDSs) in quasi-two-dimensional toroidally trapped Bose-Einstein condensates, focussing on atomic realisations thereof. Unlike the well-known planar dark solitons, exact analytic expressions for RDSs are not known. We address this problem by presenting exact localized soliton-like solutions to the radial Gross-Pitaevskii equation. To date, RDSs have not been experimentally observed in cold atomic gases, either. To this end, we propose two protocols for their creation in experiments. It is also currently well known that in dimensions higher than one, (ring) dark solitons are susceptible, in general, to an irreversible decay into vortex-antivortex pairs through the snake instability. We show that the snake instability is caused by an unbalanced quantum pressure across the soliton's notch, linking the instability to the Bogoliubov-de Gennes spectrum. In particular, if the angular symmetry is maintained (or the toroidal trapping is restrictive enough), we show that the RDS is stable (long-lived with a lifetime of order seconds) in two dimensions. Furthermore, when the decay does take place, we show that the snake instability can in fact be reversible, and predict a previously unknown revival phenomenon for the original (many-)RDS system: the soliton structure is recovered and all the point-phase singularities (i.e. vortices) disappear. Eventually, however, the decay leads to an example of quantum turbulence; a quantum example of the laminar-to-turbulent type of transition.

Effect of SX-3228, a selective ligand for the BZ1 receptor, on sleep and waking during the light-dark cycle in the rat

The effects of the benzodiazepine1 (BZ1) receptor agonist SX-3228 were studied in rats (N = 12) implanted for chronic sleep procedures. Administration of 0.5, 1.0 and 2.5 mg/kg SX-3228, sc, to rats 1 h after the beginning of the light phase of the light-dark cycle induced a significant reduction of rapid-eye-movement sleep (REMS) during the third recording hour. Moreover, slow wave sleep (SWS) was increased during the fourth recording hour after the two largest doses of the compound. Administration of 0.5, 1.0 and 2.5 mg/kg SX-3228 one hour after the beginning of the dark period of the light-dark cycle caused a significant and maintained (6-h recording period) reduction of waking (W), whereas SWS and light sleep (LS) were increased. REMS values tended to increase during the entire recording period; however, the increase was statistically significant only for the 1.0 mg/kg dose during the first recording hour. In addition, a significant and dose-related increase of power density in the delta and the theta regions was found during nonREM sleep (LS and SWS) in the dark period. Our results indicate that SX-3228 is a potent hypnotic when given to the rat during the dark period of the light-dark cycle. Moreover, the sleep induced by SX-3228 during the dark phase closely resembles the physiological sleep of the rat.

Natural preference of zebrafish (Danio rerio) for a dark environment

The zebrafish (Danio rerio) has been used as a model in neuroscience but knowledge about its behavior is limited. The aim of this study was to determine the preference of this fish species for a dark or light environment. Initially we used a place preference test and in a second experiment we applied an exit latency test. A two-chamber aquarium was used for the preference test. The aquarium consisted of a black chamber and a white chamber. In the first experiment the animal was placed in the aquarium and the time spent in the two compartments was recorded for 10 min. More time was spent in the black compartment (Wilcoxon matched-pairs signed-rank test, T = 7, N1 = N2 = 18, P = 0.0001). In the second experiment the animal was placed in the black or white compartment and the time it took to go from the initial compartment to the opposite one was recorded. The test lasted a maximum of 10 min. The results showed that the animal spent more time to go from the black to the white compartment (Mann-Whitney rank sum test, T = 48, N1 = 9, N2 = 8, P<0.0230). These data suggest that this fish species has a natural preference for a dark environment and this characteristic can be very useful for the development of new behavioral paradigms for fish.

Pupil size following dark adaptation in patients with retinitis pigmentosa

According to the equivalent light hypothesis, molecular defects in the photoreceptor lead to a continuous activation of the photoreceptor cascade in a manner equivalent to real light. The consequences in diseases such as retinitis pigmentosa (RP) are as disruptive to the cells as real light. Two forms of the equivalent light hypothesis can be distinguished: strong - mutations in rhodopsin or other cascade proteins in some forms of RP continuously excite the visual phototransduction cascade; weak - disruption of outer segments in all patients with RP eliminates circulating dark current and blocks neurotransmitter release in a manner similar to real light. Both forms of the equivalent light hypothesis predict that pupils of patients with RP will be constricted like those of normal subjects in the light. The purpose of this study was to test the equivalent light hypothesis by determining whether steady-state pupil diameter following full dark adaptation is abnormally small in any of a sample of patients with RP. Thirty-five patients with RP and 15 normal subjects were tested. Direct steady-state pupillometric measures were obtained from one eye in a full-field dome after 45 min of dark adaptation by videotaping the pupil with an infrared camera. Mean pupil diameter in the dark was comparable (t = -0.15, P = 0.88) between patients with RP (6.85 ± 0.58 mm) and normal subjects (6.82 ± 0.76 mm). The results of the present study are clearly counter to the prediction of the second (weaker) form of the equivalent light hypothesis.

Numerical Studies of Dark Energy Models and Observations

The cosmological standard view is based on the assumptions of homogeneity, isotropy and general relativistic gravitational interaction. These alone are not sufficient for describing the current cosmological observations of accelerated expansion of space. Although general relativity is extremely accurately tested to describe the local gravitational phenomena, there is a strong demand for modifying either the energy content of the universe or the gravitational interaction itself to account for the accelerated expansion. By adding a non-luminous matter component and a constant energy component with negative pressure, the observations can be explained with general relativity. Gravitation, cosmological models and their observational phenomenology are discussed in this thesis. Several classes of dark energy models that are motivated by theories outside the standard formulation of physics were studied with emphasis on the observational interpretation. All the cosmological models that seek to explain the cosmological observations, must also conform to the local phenomena. This poses stringent conditions for the physically viable cosmological models. Predictions from a supergravity quintessence model was compared to Supernova 1a data and several metric gravity models were studied with local experimental results. Polytropic stellar configurations of solar, white dwarf and neutron stars were numerically studied with modified gravity models. The main interest was to study the spacetime around the stars. The results shed light on the viability of the studied cosmological models.

The inactivation of the basolateral nucleus of the rat amygdala has an anxiolytic effect in the elevated T-maze and light/dark transition tests

Pharmacological evidence indicates that the basolateral nucleus of the amygdala (BLA) is involved in the mediation of inhibitory avoidance but not of escape behavior in the elevated T-maze test. These defensive responses have been associated with generalized anxiety disorder (GAD) and panic disorder, respectively. In the present study, we determined whether the BLA plays a differential role in the control of inhibitory avoidance and escape responses in the elevated T-maze. Male Wistar rats (250-280 g, N = 9-10 in each treatment group) were pre-exposed to one of the open arms of the maze for 30 min and 24 h later tested in the model after inactivation of the BLA by a local injection of the GABA A receptor agonist muscimol (8 nmol in 0.2 µL). It has been shown that a prior forced exposure to one of the open arms of the maze, by shortening latencies to withdrawal from the open arm during the test, improves the escape task as a behavioral index of panic. The effects of muscimol in the elevated T-maze were compared to those caused by this GABA agonist in the avoidance reaction generated in the light/dark transition test. This defensive behavior has also been associated with GAD. In the elevated T-maze, intra-BLA injection of muscimol impaired inhibitory avoidance (control: 187.70 ± 14.90 s, muscimol: 37.10 ± 2.63 s), indicating an anxiolytic effect, without interfering with escape performance. The drug also showed an anxiolytic effect in the light/dark transition test as indicated by the increase in the time spent in the lighted compartment (control: 23.50 ± 2.45 s, muscimol: 47.30 ± 4.48 s). The present findings point to involvement of the BLA in the modulation of defensive responses that have been associated with GAD.

Carnes PSE (Pale, Soft, Exudative) e DFD (Dark, Firm, Dry) em lombo suíno numa linha de abate industrial

A necessidade para uma maior produção de carne magra em suínos tem acarretado modificações nas características bioquímicas do músculo conduzindo ao desenvolvimento das anomalias nas suas cores, as denominadas carnes PSE e DFD. Estas carnes por apresentarem alterações de suas propriedades funcionais, resultam em grandes perdas econômicas. Nesse experimento, foram utilizadas 946 amostras de Longissimus dorsi m., lombos de suínos da linhagem Dalland, machos castrados e fêmeas, com 100 dias de idade, em um Frigorífico localizado na Região Sul do País. Os lombos foram classificados com base no valor de L*24 h e pH24 h. Foi constatada uma incidência de 22,8% de carnes PSE, 1,0% de DFD e 76,2% de normal. Esses valores relativamente altos de carnes PSE mostram a necessidade de se realizar controles no seu manejo pré e pós-abate para a manutenção da qualidade da carne e evitar o excessivo prejuízo econômico dos frigoríficos decorrentes dessas anormalidades.

The light and dark sides of perfectionism : implications for health and well-being

The present work presents two studies that examined the association of perfectionism, operationally defined by Hewi t t and Fl e t t ' s (1991) multidimensional mode l of perfectionism, with health and subjective well-being (SWB). The underlying question of this research was whether perfectionism could be beneficial as well as detrimental to health and well-being, as this is one of the mos t highly debated questions in the current literature. In samples of relatively healthy university students (n = 538) and community adults suffering from various chronic illnesses (n = 772), results from Study One indicated that socially prescribed perfectionism (SPP) is directly associated wi th poor e r he a l th and well-being. Results further showed f rom a personcentered perspective that there is a l a rge group of individuals wi th high levels of SPP and that i t is indeed these individuals who reported the poorest health and lowe s t levels of well-being. Other-oriented perfectionism was found to be unrelated to health and SWB. Findings revealed that when perfectionism is self-imposed (i.e., self-oriented perfectionism; SOP), i t is neither healthy nor unhealthy in an absolute sense. From the variable-centered perspective, this conclusion was supported by the f a c t tha t SOP was associated wi th both positive (e.g., be t t e r mental health and highe r levels of SWB in the student sample), and nega t ive correlates (e.g., higher levels of negative affect, stress, and neuroticism in both samples). Evidence f rom the chronically-ill sample further substantiated this conclusion by showing that there may be an optimal level of SOP, because mode r a t e levels of SOP we r e found to be associated with be t t e r health and highe r levels of SWB, whereas levels tha t we r e too low or too high we r e found to be associated with poor e r health and lowe r levels of SWB. Findings f rom the person-centered approach we r e particularly informative, in that they not only demonstrated tha t unique profiles of
