Företagsamhet i skola och utbildning : lärares tankar om förutsättningarna att nå målen i temaområdet Deltagande, demokrati och entreprenörskap

Developing students’ enterprise and proactive approaches to life have been goals of Finnish public education since its introduction. Still, education in Finland today is criticized for not reaching these goals and for overlooking the development of students’ enterprise. The role of enterprise education is ambivalent. On the one hand, enterprise education is advocated as the solution to many of the alleged problems in public education; on the other hand, the pedagogical ideas that enterprise education builds on appear to coincide with the contemporary understanding of “good education.” The thesis discusses what sets enterprise education apart from other types of education and teaching. Notably, the pedagogical foundations for enterprise education are not necessarily solid or sufficiently explored. Thus, the overall aim of the thesis is to explore the conditions for developing enterprise in education. Sloyd, as a school subject that promotes handicraft-based education, has long been attributed as having the potential to develop students’ character and person; similarly, it is also identified as being well suited for developing student enterprise. Enterprise education is not specific to sloyd, however. In fact, developing enterprise is a cross-curricular goal for basic education. In a subject-focused educational structure and culture, the development of an enterprising mindset in students is a common concern for all teachers. Thus, an understanding of the conditions for enterprise education must not be limited to one school subject; rather, the nature of the phenomenon requires a cross-curricular approach. Altogether, the conditions for enterprise education appear to be in need of further research. In addition to a subject-focused structure, other influencing factors that are mentioned in discussions on enterprise education include the need for a more enterprising working culture in school. Importantly, another key factor is the individual teacher’s pedagogical philosophy, which constitutes the frame of reference that informs how he or she understands and interprets his or her profession. Notably, the conditions for enterprise education are poor unless a teacher’s pedagogical philosophy emphasizes a focus on enterprise. The empirical research uses a hermeneutical approach and focuses on exploring teachers’ views on the conditions for reaching the national goals related to students’ enterprise. The interview study was conducted among class and subject teachers around Swedish-speaking Finland. The study shows that teachers view themselves as the most important factor for a focus on enterprise. Teachers have also identified a vast number of contextual factors that influence, support, or counteract a focus on enterprise. Structure, culture, resources, and curriculum, as well as numerous societal factors, all interact to affect the conditions for enterprise education. The prevailing culture of subject focus poses a challenge to enterprise education. At the same time, however, a focus on enterprise can be seen as a natural tendency in grades one to six. Indeed, teachers of all grade levels interpret the development of a proactive approach to life as one of education’s core values. Altogether, the thesis offers a deepened and nuanced understanding of the conditions for enterprise education. While the public education system in Finland seems to have some favourable basic conditions for enterprise education, multifaceted challenges must be faced if the national goals related to enterprise are to be reached.

Y-sukupolven johtaminen – odotukset esimiestyöltä

Y-sukupolven oikeantyylinen johtaminen sekä osaamisen hyödyntäminen ja kehittäminen ovat johtamisen haasteena organisaatioissa, jotka toimivat digitaalista osaamista vaativien tuotteiden ja palvelujen parissa. Tämän tutkimuksen tarkoituksena oli tutkia, minkälaisia odotuksia Y-sukupolvella on esimiestyötä ja johtamista kohtaan. Tutkimuksen tavoitteena oli tuottaa tutkimuksen kohdeyrityksen johtamisen kehittämistä varten nuorten työntekijöiden odotukset heihin kohdistuvasta esimiestyöstä. Tutkimuksen tavoitteena oli myös tuottaa tutkittua tietoa Y-sukupolven johtamista koskevaan keskusteluun. Tutkimus oli laadullinen tutkimus, joka toteutettiin haastattelemalla kohdeyrityksen nimeämästä joukosta 12 Y-sukupolven edustajaa. Tutkimusmenetelmänä oli puolistrukturoitu teemahaastattelu. Haastatteluissa kohderyhmään kuuluvat kertoivat omiin mielipiteisiinsä perustuen ajatuksiaan ja odotuksiaan tutkijan määrittämiin teemoihin. Haastatteluteemat olivat: työ ja työn merkitys, kokemukset ja odotukset esimieheen liittyen sekä heidän oman osaamisen hyödyntäminen ja kehittäminen. Tutkimuksen tuloksena havaittiin, että Y-sukupolvi odottaa esimiestyöltä ensisijaisesti johtamista. Esimiehen täytyy pitää organisaatiossa langat käsissään; toimia suunnannäyttäjänä, organisoida ja olla jämäkkä. Esimiehen tulee olla ominaisuuksiltaan kyvyiltään sellainen, jonka johtaminen on selkeää, oikeudenmukaista ja vuorovaikutteista. Y-sukupolvi odottaa selkeitä tavoitteita, oikeudenmukaista ja tasapuolista kohtelua ja palkkaa sekä jatkuvaa palautteeseen ja sparraamiseen liittyvää vuorovaikutusta esimiehen kanssa. Y-sukupolvi odottaa myös, että esimies hyödyntää ja kehittää heidän osaamistaan.

Hysteresis Losses in Sintered NdFeB Permanent Magnets in Rotating Electrical Machines

Permanent magnet materials are nowadays widely used in the electrical machine manufacturing industry. Eddy current loss models of permanent magnets used in electrical machines are frequently discussed in research papers. In magnetic steel materials we have, in addition to eddy current losses, hysteresis losses when AC or a rotating flux travels through the material. Should a similar phenomenon also be taken into account in calculating the losses of permanent magnets? Actually, every now and then authors seem to assume that some significant hysteresis losses are present in rotating machine PMs. This paper studies the mechanisms of possible hysteresis losses in PMs and their role in PMs when used in rotating electrical machines.

Direct-Driven Interior Magnet Permanent Magnet Synchronous Motors for a Full Electric Sports Car

The design process of direct-driven permanent magnet synchronous machines (PMSMs) for a full electric 4 ´ 4 sports car is presented. The rotor structure of the machine consists of two permanent magnet layers embedded inside the rotor laminations thus resulting in some inverse saliency, where the q-axis inductance is larger than the d-axis one. An integer slot stator winding was selected to fully take advantage of the additional reluctance torque. The performance characteristics of the designed PMSMs were calculated by applying a twodimensional finite element method. Cross-saturation between the d- and q-axes was taken into account in the calculation of the synchronous inductances. The calculation results are validated by measurements.

Intracranial Nimodipine Implant: Feasibility and Implications for the Treatment of Subarachnoid Hemorrhage – A Pre-Clinical Study

Intracranial aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening condition requiring immediate neurocritical care. A ruptured aneurysm must be isolated from arterial circulation to prevent rebleeding. Open surgical clipping of the neck of the aneurysm or intra-arterial filling of the aneurysm sack with platinum coils are major treatment strategies in an acute phase. About 40% of the patients suffering from aSAH die within a year of the bleeding despite the intensive treatment. After aSAH, the patient may develop a serious complication called vasospasm. Major risk for the vasospasm takes place at days 5–14 after the primary bleeding. In vasospasm, cerebral arteries contract uncontrollably causing brain ischemia that may lead to death. Nimodipine (NDP) is used to treat of vasospasm and it is administrated intravenously or orally every four hours for 21 days. NDP treatment has been scientifically proven to improve patients’ clinical outcome. The therapeutic effect of L-type calcium channel blocker NDP is due to the ability to dilate cerebral arteries. In addition to vasodilatation, recent research has shown the pleiotropic effect of NDP such as inhibition of neuronal apoptosis and inhibition of microthrombi formation. Indeed, NDP inhibits cortical spreading ischemia. Knowledge of the pathophysiology of the vasospasm has evolved in recent years to a complex entity of early brain injury, secondary injuries and cortical spreading ischemia, instead of being pure intracranial vessel spasm. High NDP levels are beneficial since they protect neurons and inhibit the cortical spreading ischemia. One of the drawbacks of the intravenous or oral administration of NPD is systemic hypotension, which is harmful particularly when the brain is injured. Maximizing the beneficial effects and avoiding systemic hypotension of NDP, we developed a sustained release biodegradable NDP implant that was surgically positioned in the basal cistern of animal models (dog and pig). Higher concentrations were achieved locally and lower concentrations systemically. Using this treatment approach in humans, it may be possible to reduce incidence of harmful hypotension and potentiate beneficial effects of NDP on neurons. Intracellular calcium regulation has a pivotal role in brain plasticity. NDP blocks L-type calcium channels in neurons, substantially decreasing intracellular calcium levels. Thus, we were interested in how NDP affects brain plasticity and tested the hypothesis in a mouse model. We found that NDP activates Brain-derived neurotrophic factor (BDNF) receptor TrkB and its downstream signaling in a reminiscent of antidepressant drugs. In contrast to antidepressant drugs, NDP activates Akt, a major survival-promoting factor. Our group’s previous findings demonstrate that long-term antidepressant treatment reactivates developmental-type of plasticity mechanisms in the adult brain, which allows the remodeling of neuronal networks if combined with appropriate rehabilitation. It seems that NDP has antidepressant-like properties and it is able to induce neuronal plasticity. In general, drug induced neuronal plasticity has a huge potential in neurorehabilitation and more studies are warranted.
