Unemployment duration and heterogenous search behavior among Swedish disabled workers

Return to employment, after a period of unemployment, is analyzed for a large sample of Swedish occupationally disabled workers. A piece-wise constant model is used, extended to allow for Gamma heterogeneity. Three competing exits from unemployment are accounted for; regular employment, sheltered/subsidized employment and withdrawal from the labor force. The model is also generalized by accounting for differing search behavior within the population. The hazard rate is constant or slightly increasing over time, for exit to some kind of employment. However, for exit from unemployment by leaving the labor force, the hazard shows quite strong positive duration dependence. Men tend to be more probable to leave unemployment for regular employment, and less probable than women to leave the labor force. The probability of finding regular employment is smallest for workers with psychological disabilities, while high-school or university education as well as previous professional experience increases the hazard rate for regular employment. The heterogeneity due to differing search behavior appears to be at least as important as the Gamma heterogeneity. The estimated probabilities of no search for one particular exit varies, across exits and subsamples, between 0.0 and 0.4.Unemployment

Policy programmes only for a few? Participation in labour market programmes among Swedish disabled workers

In a large sample of Swedish unemployed disabled workers, the workers participate in between zero and ten policy programmes during their unemployment spell. Clustering of programmes to about half of the sample is prominent. The number of programmes is modelled as a standard count data model, as a zero-inflated model and as a hurdle model. The most important question is whether disadvantaged workers are more or less probable to participate in programmes. The empirical analysis shows that participants in programmes have a stronger labour market attachment, than do non-participants. The number of programmes differ across subgroups of the disabled, and workers with impaired hearing or vision and psychical disabilities are expected to participate in more programmes than other groups. The supply of policy programmes is also of importance. In particular, for individuals living in municipalities with many disabled unemployed, the expected number of programmes is lower. Descriptive inspection of how the unemployment spells end, shows that non-participants, i.e. workers with zero programmes, withdraw from the labour force to a larger extent than do programme participants

Cofiniteness of weakly Laskerian local cohomology modules

Let $I$ be an ideal of a Noetherian ring R and M be a finitely generated R-module. We introduce the class of extension modules of finitely generated modules by the class of all modules $T$ with $\dim T\leq n$ and we show it by ${\rm FD_{\leq n}}$ where $n\geq -1$ is an integer. We prove that for any ${\rm FD_{\leq 0}}$(or minimax) submodule N of $H^t_I(M)$ the R-modules ${\rm Hom}_R(R/I,H^{t}_I(M)/N) {\rm and} {\rm Ext}^1_R(R/I,H^{t}_I(M)/N)$ are finitely generated, whenever the modules $H^0_I(M)$, $H^1_I(M)$, ..., $H^{t-1}_I(M)$ are ${\rm FD_{\leq 1}}$ (or weakly Laskerian). As a consequence, it follows that the associated primes of $H^{t}_I(M)/N$ are finite. This generalizes the main results of Bahmanpour and Naghipour, Brodmann and Lashgari, Khashyarmanesh and Salarian, and Hong Quy. We also show that the category $\mathscr {FD}^1(R,I)_{cof}$ of $I$-cofinite ${\rm FD_{\leq1}}$ ~ $R$-modules forms an Abelian subcategory of the category of all $R$-modules.Comment: 8 pages, some changes has been don

Controlled environmental agriculture & the need for innovations networks

MSc in International Business and TradeThis thesis explores which innovation systems that facilitates growth for Controlled Environment Agriculture (CEA) companies and to successfully operate within the food industry. This was done by interviewing several companies within the CEA industry as well as relevant governmental organizations. The theoretical framework was constructed to support the analysis and was based on several innovation systems theories as well as the Multi Level Perspective (MLP). The research found that the CEA companies to a great extent rely on several important actors within their different innovation systems to successfully grow their business over time . Investors emerged as the single most important actor for CEA firms, especially during the startup phase when funding was crucial for scaling up their operations and achieving profitability. Collaboration with governmental institutions and universities are also very important for CEA companies, both when it comes to financial and research support but also as a platform for future working competence. Additionally, the study identified a trend where younger companies rely on local and regional innovation systems, while more mature companies seek engagement in larger global systems for increased funding, knowledge, and support. In conclusion, the success of CEA companies is closely tied to the involvement of the relevant actors within their innovation systems to overcome the obstacles that the companies are facing where financial partners and universities proved to be the most important actors in the startup phase, but where laws and regulations were an important indirect factor for the companies

Cofiniteness and coassociated primes of local cohomology modules

Let $R$ be a noetherian ring, \fa an ideal of $R$ such that \dim R/\fa=1 and $M$ a finite $R$--module. We will study cofiniteness and some other properties of the local cohomology modules \lc^{i}_{\fa}(M). For an arbitrary ideal \fa and an $R$--module $M$ (not necessarily finite), we will characterize \fa--cofinite artinian local cohomology modules. Certain sets of coassociated primes of top local cohomology modules over local rings are characterized.Comment: 10 pages, to appear in Mathematica Scandinavic

Altered metabolic parameters in association with antipsychotic medication use in diabetes:A population based case-control study

Aims: This study assess differences in clinical variables in diabetes patients prescribed antipsychotic medication and determines relative schizophrenia prevalence in the diabetes population. Methods: This population-based case-control study utilizing Scotland's national diabetes registry (SCI-diabetes) and linked psychiatric hospital discharge data (SMR04) established diabetes phenotypes in a patient cohort prescribed long term antipsychotic medication (n = 2362) (cases). Cases were matched 1:10 to diabetes patients not prescribed antipsychotic medication (controls) for BMI, gender; diabetes type; birth year; diagnosis date; smoking status. Sub-groups with defined schizophrenia (n = 196) or bipolar disorder (n = 190) were further examined. Schizophrenia prevalence in the diabetes versus general population was compared. Results: During follow up, antipsychotic prescription was associated with lower HbA1c (55.1 (95% CI 54.5-55.8) or 7.2 (95% CI 7.1-7.3)% vs 58.2 (58.0-58.4) mmol or 7.5 (95% CI 7.5-7.5)% p &lt;0.001) lower serum total cholesterol, 4.2 (4.1-4.2) vs 4.3 (4.2-4.3) mmol/l, p &lt;0.001, lower blood pressure (systolic 130 (130.17-131.29) vs 134 (134.3-134.7) mmHg, p &lt;0.001), higher prescription of oral hypoglycaemic medication (42% (40-45) vs 38% (37-39) p &lt;0.001), similar statin prescriptions (85% (81-89) vs 85% (84-86), p = 0.55), and lower retinopathy rates (28% (25.6-30.5) vs 32% (31.5-33.1), p &lt;0.001). HbA1c at diagnosis was similar (p = 0.27). Schizophrenia prevalence was higher in the diabetes versus general population with differences across age groups (Scottish population versus diabetic population rate of 522.2 (522.1-522.3) versus 717.4 (703.4-731.9) per 100,000). Conclusions: We confirm higher diabetes rates in schizophrenia up to age 70, similar attendance rates and clinical measurements that are not worse in a large well-matched population-based Scottish sample prescribed antipsychotic medication versus matched general diabetes patients.</p

Företagsöverlåtelse vid generationsskifte - Problem, möjligheter och framtida aspekter

Det här arbetet kommer att belysa den problematik som kan uppkomma vid ett generationsskifte av ett fåmansföretag. Det kommer att handla om de grundläggande beskattningsregler som råder och de tillvägagångssätt som kan komma att utnyttjas. Det är ett område med stora förändringar dels den senaste tiden och dels den inom den snara framtiden. Vid ett generationsskifte är det inte bara det hårda rekvisiten som måste beaktas utan även de så kallade familjepremisserna måste vara uppfyllda. Uppsatsen kommer att berör dessa båda områden och föra en diskussion om de möjligheter man har att uppfylla alla ställda krav och önskemål. Men det är inte bara ett nationellt fenomen, Sverige är en del av övriga världen och ur ett skatteplaneringsperspektiv måste man blicka ut över gränser för att eventuellt finna ytterligare möjligheter. Med dessa alternativa möjligheter kommer även vissa problem
