Career decision making, stability and actualization of career intentions : the case of entrepreneurial intentions

Career counselors are often concerned with stability and likelihood of implementation of clients' career intentions. It is often assumed that the status in career decision making (CDM) is one likely indicator; yet, empirical support for this assumption is sparse. The present study focused on entrepreneurial career intentions (EI) and showed that German university students (N = 1,221), with high EI can be found in very different empirically derived CDM statuses that range from preconcern to mature decidedness. Longitudinal analyses (n = 561) showed that career choice foreclosure (high decidedness/low exploration) related to more EI stability and that mature decidedness (high decidedness/high exploration) amplified effects of EI on opportunity identification, a form of EI actualization. The results imply that CDM statuses are useful to estimate stability and actualization of career intentions.

Acylation of chiral alcohols: a simple procedure for chiral GC analysis

The use of iodine as a catalyst and either acetic or trifluoroacetic acid as a derivatizing reagent for determining the enantiomeric composition of acyclic and cyclic aliphatic chiral alcohols was investigated. Optimal conditions were selected according to the molar ratio of alcohol to acid, the reaction time, and the reaction temperature. Afterwards, chiral stability of chiral carbons was studied. Although no isomerization was observed when acetic acid was used, partial isomerization was detected with the trifluoroacetic acid. A series of chiral alcohols of a widely varying structural type were then derivatized with acetic acid using the optimal conditions. The resolution of the enantiomeric esters and the free chiral alcohols was measured using a capillary gas chromatograph equipped with a CP Chirasil-DEX CB column. The best resolutions were obtained with 2-pentyl acetates (α = 3.00) and 2-hexyl acetates (α = 1.95). This method provides a very simple and efficient experimental workup procedure for analyzing chiral alcohols by chiral-phase GC.

Patients' preferences on information and involvement in decision-making in gastrointestinal surgery

Contexte et but de l'étude: La relation médecin-patient a subi d'importants changements et l'actuelle émancipation des patients a conduit à un véritable partenariat dans la prise de décisions thérapeutiques. Notre étude a pour but de déterminer les préférences des patients pour différents aspects de la prise de décisions au cours d'un traitement et de ses potentielles complications, de même que la quantité et le type d'information souhaitée avant une intervention chirurgicale digestive. Patients et méthodes : Il s'agit d'une étude prospective non-randomisée basée sur un questionnaire donné lors de la consultation préopératoire à 254 patients consécutifs prévus pour une chirurgie gastro-intestinale élective. Résultats : Pour les potentielles complications chirurgicales et la possibilité d'un séjour aux soins intensifs, 64% des patients souhaitent participer activement aux décisions médicales, et respectivement 89% et 60% des patients aimeraient discuter d'une éventuelle réanimation cardio-pulmonaire et de limitations au traitement. Respectivement 73%, 77% et 47% des patients ont souhaité une information très détaillée, une infoimation pour une possible hospitalisation en soins intensifs ou une éventuelle réanimation cardiaque. Les patients âgés ou avec un niveau de formation bas étaient significativement moins intéressés à une prise de décision partagée (p=0.003 et 0.015) et à une information complète (p=0.03 et 0.05), De plus, l'implication des familles dans les prises de décision n'était favorisée que si le patient est en coma (74%), et significativement moins importante chez les personnes âgées et de sexe masculin (p=0.04 et 0.03 respectivement). Ni le type de chirurgie prévue (majeure ou mineure) ni la sévérité de la pathologie (cancer ou non) ne furent des facteurs statistiquement significatifs pour un désir plus élevé de partager la prise de décision, pour plus d'information ou pour impliquer d'avantage la famille. Conclusions : Notre étude démontre que la majorité des patients chirurgicaux souhaitent recevoir une information préopératoire complète concernant leur maladie et le traitement planifié. Ils considèrent également comme crucial d'être impliqués dans les prises de décisions thérapeutiques pour le traitement et pour les possibles complications. Le rôle de la famille est limité aux situations ou le patient n'est plus en mesure de participer aux décisions.

Agency problems with non-smooth decision profiles: the case of monopoly under product quality

A method for dealing with monotonicity constraints in optimal control problems is used to generalize some results in the context of monopoly theory, also extending the generalization to a large family of principal-agent programs. Our main conclusion is that many results on diverse economic topics, achieved under assumptions of continuity and piecewise differentiability in connection with the endogenous variables of the problem, still remain valid after replacing such assumptions by two minimal requirements.

Are Evaluation of ICTs Investment Using Decision Support Systems:Case Applications from Distributor's and End User's Perspective Group Decision

The evaluation of investments in advanced technology is one of the most important decision making tasks. The importance is even more pronounced considering the huge budget concerning the strategic, economic and analytic justification in order to shorten design and development time. Choosing the most appropriate technology requires an accurate and reliable system that can lead the decision makers to obtain such a complicated task. Currently, several Information and Communication Technologies (ICTs) manufacturers that design global products are seeking local firms to act as their sales and services representatives (called distributors) to the end user. At the same time, the end user or customer is also searching for the best possible deal for their investment in ICT's projects. Therefore, the objective of this research is to present a holistic decision support system to assist the decision maker in Small and Medium Enterprises (SMEs) - working either as individual decision makers or in a group - in the evaluation of the investment to become an ICT's distributor or an ICT's end user. The model is composed of the Delphi/MAH (Maximising Agreement Heuristic) Analysis, a well-known quantitative method in Group Support System (GSS), which is applied to gather the average ranking data from amongst Decision Makers (DMs). After that the Analytic Network Process (ANP) analysis is brought in to analyse holistically: it performs quantitative and qualitative analysis simultaneously. The illustrative data are obtained from industrial entrepreneurs by using the Group Support System (GSS) laboratory facilities at Lappeenranta University of Technology, Finland and in Thailand. The result of the research, which is currently implemented in Thailand, can provide benefits to the industry in the evaluation of becoming an ICT's distributor or an ICT's end user, particularly in the assessment of the Enterprise Resource Planning (ERP) programme. After the model is put to test with an in-depth collaboration with industrial entrepreneurs in Finland and Thailand, the sensitivity analysis is also performed to validate the robustness of the model. The contribution of this research is in developing a new approach and the Delphi/MAH software to obtain an analysis of the value of becoming an ERP distributor or end user that is flexible and applicable to entrepreneurs, who are looking for the most appropriate investment to become an ERP distributor or end user. The main advantage of this research over others is that the model can deliver the value of becoming an ERP distributor or end user in a single number which makes it easier for DMs to choose the most appropriate ERP vendor. The associated advantage is that the model can include qualitative data as well as quantitative data, as the results from using quantitative data alone can be misleading and inadequate. There is a need to utilise quantitative and qualitative analysis together, as can be seen from the case studies.

Päätöspuun käyttö tutkamaalien initialisoinnissa

Suomen ilmatilaa valvotaan reaaliaikaisesti, pääasiassa ilmavalvontatutkilla. Ilmatilassa on lentokoneiden lisäksi paljon muitakin kohteita, jotka tutka havaitsee. Tutka lähettää nämä tiedot edelleen ilmavalvontajärjestelmään. Ilmavalvontajärjestelmä käsittelee tiedot, sekä lähettää ne edelleen esitysjärjestelmään. Esitysjärjestelmässä tiedot esitetään synteettisinä merkkeinä, seurantoina joista käytetään nimitystä träkki. Näiden tietojen puitteissa sekä oman ammattitaitonsa perusteella ihmiset tekevät päätöksiä. Tämän työn tarkoituksena on tutkia tutkan havaintoja träkkien initialisointipisteessä siten, että voitaisiin määritellä tyypillinen rakenne sille mikä on oikea ja mikä väärä tai huono träkki. Tämän lisäksi tulisi ennustaa, mitkä Irakeista eivät aiheudu ilma- aluksista. Saadut tulokset voivat helpottaa työtä havaintojen tulkinnassa - jokainen lintuparvi ei ole ehdokas seurannaksi. Havaintojen luokittelu voidaan tehdä joko neurolaskennalla tai päätöspuulla. Neurolaskenta tehdään neuroverkoilla, jotka koostuvat neuroneista. Päätöspuu- luokittelijat ovat oppivia tietorakenteita kuten neuroverkotkin. Yleisin päätöpuu on binääripuu. Tämän työn tavoitteena on opettaa päätöspuuluokittelija havaintojen avulla siten, että se pystyy luokittelemaan väärät havainnot oikeista. Neurolaskennan mahdollisuuksia tässä työssä ei käsitellä kuin teoreettisesti. Työn tuloksena voi todeta, että päätöspuuluokittelijat ovat erittäin kykeneviä erottamaan oikeat havainnot vääristä. Vaikka tulokset olivat rohkaiseva, lisää tutkimusta tarvitaan määrittelemään luotettavammin tekijät, jotka parhaiten suorittavat luokittelun.

A territorial approach to R&D subsidies: Empirical evidence for Catalonian firms

Using a database of 2,263 responses to R&D public calls in Catalonia, during the period 2007–2010, this paper proceeds to analyse the potential interaction of the territorial and policy dimensions with the propensity to apply for, and be awarded, a public R&D subsidy. Controlling for characteristics at the firm and project level, we estimate models using a twostep procedure. In the first step, our results suggest that large firms which export and which belong to high-tech manufactures are more likely to participate in a public R&D call. Furthermore, both urban location and past experience of such calls have a positive effect. Our territorial proxy of information spillovers shows a positive sign, but this is only significant at intra-industry level. Membership of one of the sectors prioritized by the Catalan government, perhaps surprisingly, does not have a significant impact. In the second step, our results show that cooperative projects, SMEs or old firms shows a positive effect on the probability of obtaining a public subsidy. Finally, the cluster policy does not show a clear relationship with the public R&D call, suggesting that cluster policies and R&D subsidies follow different goals. Our results are in line with previous results in the literature, but they highlight the unequal territorial distribution of the firms which apply and the fact that policymakers should interlink the decision criteria for their public call with other policies.

Longitudinal study of informed consent in innovative therapy research: experience and provisional recommendations from a multicenter trial of intracerebral grafting.

BACKGROUND: There is an urgent need to assess and improve the consent process in clinical trials of innovative therapies for neurodegenerative disorders. METHODS: We performed a longitudinal study of the consent of Huntington's disease patients during the Multicenter Fetal Cell Intracerebral Grafting Trial in Huntington's Disease (MIG-HD) in France and Belgium. Patients and their proxies completed a consent questionnaire at inclusion, before signing the consent form and after one year of follow-up, before randomization and transplantation. The questionnaire explored understanding of the protocol, satisfaction with the information delivered, reasons for participating in the trial and expectations regarding the transplant. Forty-six Huntington's disease patients and 27 proxies completed the questionnaire at inclusion, and 27 Huntington's disease patients and 16 proxies one year later. RESULTS: The comprehension score was high and similar for Huntington's disease patients and proxies at inclusion (72.6% vs 77.8%; P > 0.1) but only decreased in HD patients after one year. The information satisfaction score was high (73.5% vs 66.5%; P > 0.1) and correlated with understanding in both patients and proxies. The motivation and expectation profiles were similar in patients and proxies and remained unchanged after one year. CONCLUSIONS: Cognitively impaired patients with Huntington's disease were capable of consenting to participation in this trial. This consent procedure has presumably strengthened their understanding and should be proposed before signing the consent form in future gene or cell therapy trials for neurodegenerative disorders. Because of the potential cognitive decline, proxies should be designated as provisional surrogate decision-makers, even in competent patients.

Patients' characteristics associated with the decision of "do not attempt cardiopulmonary resuscitation" order in a Swiss hospital.

BACKGROUND: According to Swiss legislation, do not attempt cardiopulmonary resuscitation (DNACPR) order can be made at any time by patients only, unless the resuscitation is considered as futile, based on the doctors' evaluation. Little is known about how this decision is made, and which are the factors influencing this decision. METHODS: Observational, cross-sectional study was conducted between March and May 2013 on 194 patients hospitalized in the general internal medicine ward of a Swiss hospital. The associations between patients' DNACPR orders and gender, age, marital status, nationality, religion, number and type of comorbidities were assessed. RESULTS: 102 patients (53%) had a DNACPR order: 27% issued by the patient him/herself, 12% by his/her relatives and 61% by the medical team. Patients with a DNACPR order were significantly older: 80.7±10.8 vs. 67.5±15.1years in the "with" and "without" DNACPR order group, respectively, p<0.001. Oncologic disease was associated with a DNACPR order issued by the medical team (37.5% vs. 16.9% in the "with" and "without" DNACPR order group, respectively, p<0.05). Being protestant was associated with a DNACPR order issued by the patient (57.9% vs. 25.9% in the "with" and "without" DNACPR order group, respectively p<0.01). CONCLUSIONS: Over half of the patients admitted to a general internal medicine ward had a DNACPR order issued within the first 72h of hospitalization. Older age and oncologic disease were associated with a DNACPR decision by the medical team, while protestant religion was associated with a DNACPR decision by the patient.

Collective decision making in a heterogeneous environment: Lasius niger colonies preferentially forage at easy to learn locations

Many ants forage in complex environments and use a combination of trail pheromone information and route memory to navigate between food sources and the nest. Previous research has shown that foraging routes differ in how easily they are learned. In particular, it is easier to learn feeding locations that are reached by repeating (e.g. left-left or right-right) than alternating choices (left-right or right-left) along a route with two T-bifurcations. This raises the hypothesis that the learnability of the feeding sites may influence overall colony foraging patterns. We studied this in the mass-recruiting ant Lasius niger. We used mazes with two T-bifurcations, and allowed colonies to exploit two equidistant food sources that differed in how easily their locations were learned. In experiment 1, learnability was manipulated by using repeating versus alternating routes from nest to feeder. In experiment 2, we added visual landmarks along the route to one food source. Our results suggest that colonies preferentially exploited the feeding site that was easier to learn. This was the case even if the more difficult to learn feeding site was discovered first. Furthermore, we show that these preferences were at least partly caused by lower error rates (experiment 1) and greater foraging speeds (experiment 2) of foragers visiting the more easily learned feeder locations. Our results indicate that the learnability of feeding sites is an important factor influencing collective foraging patterns of ant colonies under more natural conditions, given that in natural environments foragers often face multiple bifurcations on their way to food sources.

Kestävän kehityksen näkökulmien huomioiminen kunnan energiaratkaisussa

Diplomityön tavoitteena on tuottaa informaatiota kunnalliseen päätöksentekoon, jonka avulla kestävän kehityksen näkökulmia voidaan huomioida kunnan energiaratkaisusta päätettäessä. Yhtenä työn lähtökohtana on ollut myös uusi EU-direktiivi, jonka mukaan ympäristönäkökohtia voidaan huomioida julkisten hankintojen tarjouspyyntömenettelyssä valintaperusteena. Tarkastelun kohteena oli kokoluokaltaan 0,5–3 MW:n aluelämpölaitokset sekä polttoaineiden tuotantoketjut. Työssä vertailtavat polttoaineet olivat metsähake, raskas polttoöljy, kevyt polttoöljy ja turve. Diplomityössä on perehdytty kestävän kehityksen käsitteeseen ja muodostettu sen mukaan ekologiselle, sosiaaliselle ja taloudelliselle näkökulmalle kunnallisen energiaratkaisun indikaattoreita. Empiirisessä osassa käsitellään kestävän kehityksen näkökulmien muodostumista Enon energiaosuuskunnan toimintaan perustuen. Käytettävät kestävän kehityksen näkökulmien mukaiset indikaattorit ovat polttoaineen tuotannosta ja käytöstä aiheutuvat kasvihuonekaasupäästöt, polttoaineen tuotannon työllisyysvaikutukset sekä energian hinnan muodostuminen osuuskunnan asiakkaille. Tässä diplomityössä tarkastelluilla kestävän kehityksen indikaattoreilla mitattuna, metsähakkeen käytöllä energiantuotannossa on positiivinen vaikutus niin kunnan kasvihuonekaasutaseessa, työllisyystilanteessa sekä myös enemmän kuluttajaystävällinen asema, lämmön hinnan vakauden ansiosta, kuin muilla työssä käsiteltävillä polttoaineilla. Polttoaineen tuotantoketjun osalta metsähakkeelle saatiin tuotannon ja käytön aiheuttamaksi kasvihuonekaasupäästöksi 2,9–4,2 g CO2-ekv/MJ. Tulos perustuu Enon energiaosuuskunnan polttoaineen hankinnassa käytössä oleviin keskimääräisiin etäisyyksiin metsäkuljetuksessa (250 m) ja kaukokuljetuksessa (15 km). Tuotannon ja käytön aiheuttamat kasvihuonekaasupäästöt olivat raskaalla polttoöljyllä 88,2 g CO2-ekv/MJ, kevyellä polttoöljyllä 85,0 g CO2-ekv/MJ ja turpeella 104,0–108,1 g CO2-ekv/MJ. Metsähakkeen osalta polttoaineen tuotannon osuus koko tarkastellun energiaketjun kasvihuonekaasupäästöistä oli noin 43–57 %. Enon energiaosuuskunnan tapauksessa vuoden 2005 odotetulla toiminta-asteella metsähakkeella tuotetun lämmön tuotantoketjun kasvihuonekaasupäästöt ovat noin 160 t CO2-ekv. Kevyellä polttoöljyllä tuotetun lämmön tuotantoketjun kasvihuonekaasupäästöt olisivat noin 3700 t CO2-ekv sekä turpeen (50 %) ja metsähakkeen (50 %) seoskäyttöön perustuvalla ketjulla noin 2300–2400 t CO2-ekv. Samaisella toiminta-asteella työllisyysvaikutukset ovat käytettäessä metsähaketta 2,2–8,6 htv, raakaöljyä 0,12 htv ja turvetta 1,4–1,6 htv. Metsähakkeen käyttö aluelämpölaitosten pääpolttoaineena takaa myös vakaan hintakehityksen osuuskunnan asiakkaille.
