Libertad condicional : propuestas para aumentar su concesión

La libertad condicional es una institución cuya aplicación no se da con la frecuencia que debería para lograr una resocialización y reinserción adecuada. Para reducir las tasas de encarcelamiento y los costes que se derivan, así como para igualar las tasas de liberados condicionales en Cataluña con las del resto del Estado, se proponen posibles mejoras para la concesión del último grado penitenciario. Las propuestas se desarrollan a partir de una investigación empírica basada en una revisión exhaustiva de los informes de pronóstico de reinserción de la Junta de Tratamiento y las resoluciones del Fiscal de Vigilancia Penitenciaria.Se formularán propuestas generales y específicas. Las primeras estarán encabezadas a modificar el punitivismo de la sociedad y la implementación de la libertad condicional. Las segundas estarán orientadas a focalizar el último grado penitenciario también a internos con alto riesgo de reincidencia, siempre y cuando se les proporcione una intervención intensiva; a mejorar y tratar tanto los factores estáticos como los dinámicos –hábitos laborales, toxicomanías, apoyo familiar– para facilitar el acceso a la libertad condicional según los actuales requisitos; a concienciar sobre la importancia de satisfacer la responsabilidad civil y a seguir la línea del modelo de riesgo, necesidad y responsividad.ABSTRACTParole is an institution whose application does not occur as often as it should to achieve resocialization and reintegration adequately.

The proposals were developed from an empirical research based on the analysis of the Treatment Assembly’s forecast reports reintegration and the Fiscal’s resolutions.It will be formulated general and specific proposals. The first one will be led to modify society’s punitivity and parole’s implementation. The second one will be directed on focusing parole in high risk prison inmates, as long as they have an intensive intervention; on improving and treat both static and dynamic factors –work habits, addictions, family support– to facilitate the access on parole under the current requirements; on raising the importance of paying the civil liability and follow the principles of the model of risk, needs and responsivity.

Educar els fills és molt complicat! Els malestars actuals de la socialització familiar

En les diferents recerques sobre la socialització familiar són cada vegada més habituals les referències dels progenitors catalans de classes mitjanes i altes a la complexitat, a les dificultats i a la tensió creixent que implica educar els fills i les filles. Sobre això, i amb la teoria de la civilització de Norbert Elias com a fil conductor, l’article es pregunta pels malestars que actualment travessa la socialització familiar i els posa en relació amb quin és l’objectiu del mateix procés en la nostra societat immersa en un capitalisme financer i flexible. Així, si la finalitat és la «socialització terciària» (Mead, 1964; Bateson, 1984), dins les famílies emergeixen un seguit de neguits i malestars lligats a l’autoritat, l’autonomia, els hàbits, els conflictes i els càstigs, les normes, les convencions i les prohibicions, etc. que, segons el parer de l’autor, cal comprendre dins del nou context social i econòmic i en relació amb els nous objectius de l’educació familiar de les famílies benestants catalanes.

Lexan Gate Arm, HR-536, 1987

Innovative Rail Ltd. of Cedar Rapids, Iowa produced a new rail/highway crossing gate arm that shows promise in two areas: a. Minimizing arm breakage, and b. Added target value to motorists. The new gate was demonstrated to the Chicago and North Western Transportation Company, and that railroad has requested its use at two crossings on an "experimental basis" to determine if its installation provides relief in those areas. On April 18, 1986, the Department observed a test of the material under field conditions with the Transportation Company. The gate received four mid-center strikes at 5 MPH by a company truck while in the lowered position, and showed no damage. In a fifth mid-center strike at 15 MPH, the gate was visibly damaged at the connection to its raising mechanism, but continued to function though at a 5-10 degree drop. Several pictures of the gate and its saddle mechanism are shown in Appendix A of this report. Innovative Rail established distributorships in the United States and Canada, and has since gone out of business.

Actin cables and the exocyst form two independent morphogenesis pathways in the fission yeast.

Cell morphogenesis depends on polarized exocytosis. One widely held model posits that long-range transport and exocyst-dependent tethering of exocytic vesicles at the plasma membrane sequentially drive this process. Here, we describe that disruption of either actin-based long-range transport and microtubules or the exocyst did not abolish polarized growth in rod-shaped fission yeast cells. However, disruption of both actin cables and exocyst led to isotropic growth. Exocytic vesicles localized to cell tips in single mutants but were dispersed in double mutants. In contrast, a marker for active Cdc42, a major polarity landmark, localized to discreet cortical sites even in double mutants. Localization and photobleaching studies show that the exocyst subunits Sec6 and Sec8 localize to cell tips largely independently of the actin cytoskeleton, but in a cdc42 and phospholipid phosphatidylinositol 4,5-bisphosphate (PIP₂)-dependent manner. Thus in fission yeast long-range cytoskeletal transport and PIP₂-dependent exocyst represent parallel morphogenetic modules downstream of Cdc42, raising the possibility of similar mechanisms in other cell types.

Exendin-4 protects beta-cells from interleukin-1 beta-induced apoptosis by interfering with the c-Jun NH2-terminal kinase pathway.

OBJECTIVE: The pro-inflammatory cytokine interleukin-1 beta (IL-1 beta) generates pancreatic beta-cells apoptosis mainly through activation of the c-Jun NH(2)-terminal kinase (JNK) pathway. This study was designed to investigate whether the long-acting agonist of the hormone glucagon-like peptide 1 (GLP-1) receptor exendin-4 (ex-4), which mediates protective effects against cytokine-induced beta-cell apoptosis, could interfere with the JNK pathway. RESEARCH DESIGN AND METHODS: Isolated human, rat, and mouse islets and the rat insulin-secreting INS-1E cells were incubated with ex-4 in the presence or absence of IL-1 beta. JNK activity was assessed by solid-phase JNK kinase assay and quantification of c-Jun expression. Cell apoptosis was determined by scoring cells displaying pycnotic nuclei. RESULTS: Ex-4 inhibited induction of the JNK pathway elicited by IL-1 beta. This effect was mimicked with the use of cAMP-raising agents isobutylmethylxanthine and forskolin and required activation of the protein kinase A. Inhibition of the JNK pathway by ex-4 or IBMX and forskolin was concomitant with a rise in the levels of islet-brain 1 (IB1), a potent blocker of the stress-induced JNK pathway. In fact, ex-4 as well as IBMX and forskolin induced expression of IB1 at the promoter level through cAMP response element binding transcription factor 1. Suppression of IB1 levels with the use of RNA interference strategy impaired the protective effects of ex-4 against apoptosis induced by IL-1 beta. CONCLUSIONS: The data establish the requirement of IB1 in the protective action of ex-4 against apoptosis elicited by IL-1 beta and highlight the GLP-1 mimetics as new potent inhibitors of the JNK signaling induced by cytokines.

Personalized touristic routes implementing semantic web on GIS

Nowadays, when a user is planning a touristic route is very difficult to find out which are the best places to visit. The user has to choose considering his/her preferences due to the great quantity of information it is possible to find in the web and taking into account it is necessary to do a selection, within small time because there is a limited time to do a trip. In Itiner@ project, we aim to implement Semantic Web technology combined with Geographic Information Systems in order to offer personalized touristic routes around a region based on user preferences and time situation. Using ontologies it is possible to link, structure, share data and obtain the result more suitable for user's preferences and actual situation with less time and more precisely than without ontologies. To achieve these objectives we propose a web page combining a GIS server and a touristic ontology. As a step further, we also study how to extend this technology on mobile devices due to the raising interest and technological progress of these devices and location-based services, which allows the user to have all the route information on the hand when he/she does a touristic trip. We design a little application in order to apply the combination of GIS and Semantic Web in a mobile device.

ERK1/2 controls Na,K-ATPase activity and transepithelial sodium transport in the principal cell of the cortical collecting duct of the mouse kidney.

The collecting duct of normal kidney exhibits significant activity of the MEK1/2-ERK1/2 pathway as shown in vivo by immunostaining of phosphorylated active ERK1/2 (pERK1/2). The MEK1/2-ERK1/2 pathway controls many different ion transports both in proximal and distal nephron, raising the question of whether this pathway is involved in the basal and/or hormone-dependent transepithelial sodium reabsorption in the principal cell of the cortical collecting duct (CCD), a process mediated by the apical epithelial sodium channel and the basolateral sodium pump (Na,K-ATPase). To answer this question we used ex vivo microdissected CCDs from normal mouse kidney or in vitro cultured mpkCCDcl4 principal cells. Significant basal levels of pERK1/2 were observed ex vivo and in vitro. Aldosterone and vasopressin, known to up-regulate sodium reabsorption in CCDs, did not change ERK1/2 activity either ex vivo or in vitro. Basal and aldosterone- or vasopressin-stimulated sodium transport was down-regulated by the MEK1/2 inhibitor PD98059, in parallel with a decrease in pERK1/2 in vitro. The activity of Na,K-ATPase but not that of epithelial sodium channel was inhibited by MEK1/2 inhibitors in both unstimulated and aldosterone- or vasopressin-stimulated CCDs in vitro. Cell surface biotinylation showed that intrinsic activity rather than cell surface expression of Na,K-ATPase was controlled by pERK1/2. PD98059 also significantly inhibited the activity of Na,K-ATPase ex vivo. Our data demonstrate that the ERK1/2 pathway controls Na,K-ATPase activity and transepithelial sodium transport in the principal cell and indicate that basal constitutive activity of the ERK1/2 pathway is a critical component of this control.

Family Support Subsidy and Children at Home Program SFY 2015, October 30, 2015

The Family Support Subsidy (FSS) program provides a monthly payment to help families with the cost of raising a child with a developmental disability. Parents of children with disabilities were very active in getting state and federal policy makers to look at how they could divert some of the funds going to institutional care. Families with severely disabled children wanted to raise their children at home but were met with a lot of resistance and policy barriers when they tried to get home-based support.

Burden of Diabetes in Iowa 1991-2009, Final Report, May 2010

The Iowa Diabetes Prevention and Control Program provides educational opportunities for health care providers via the Iowa Communications Network interactive fiber optic system. The program also certifies diabetes outpatient education programs in Iowa based on minimum criteria for quality programs. In Iowa during the past 20 years, the prevalence rate of diagnosed diabetes increased dramatically among adults: Between 1991 and 2009 the crude diabetes prevalence rate rose by 84%, from 3.8% to 7.0%. Between these years, the age‐adjusted adult diagnosed diabetes prevalence rate increased by 64%, rising from 3.7% to 6.4%. During the 18 years 1991‐93 through 2006‐08, the number of Iowa adults with diagnosed diabetes more than doubled, increasing from 78,000 to 162,000. While the Iowa Behavioral Risk Factor Surveillance System (BRFSS), upon which the numbers cited above are based, provides reliable state‐level self‐reported data on adults with diagnosed diabetes, it is unable to provide estimates of undiagnosed diabetes. National estimates put the prevalence of undiagnosed adult diabetes at about 5%, raising the estimated adult diabetes prevalence rate in Iowa to 12% (280,000 adults) (Cowie,2009). Another 5% of all Iowa adults are estimated to have diagnosed pre‐diabetes, while 25% of all Iowa adults, based on national estimates from the 2005‐06 National Health and Nutrition and Examination Survey (NHANES), likely have undiagnosed pre‐diabetes. (Cowie, 2009)

Transcriptional regulatory patterns of the myelin basic protein and malic enzyme genes by the thyroid hormone receptors alpha1 and beta1.

While there is evidence that the two ubiquitously expressed thyroid hormone (T3) receptors, TRalpha1 and TRbeta1, have distinct functional specificities, the mechanism by which they discriminate potential target genes remains largely unexplained. In this study, we demonstrate that the thyroid hormone response elements (TRE) from the malic enzyme and myelin basic protein genes (METRE and MBPTRE) respectively, are not functionally equivalent. The METRE, which is a direct repeat motif with a 4-base pair gap between the two half-site hexamers binds thyroid hormone receptor as a heterodimer with 9-cis-retinoic acid receptor (RXR) and mediates a high T3-dependent activation in response to TRalpha1 or TRbeta1 in NIH3T3 cells. In contrast, the MBPTRE, which consists of an inverted palindrome formed by two hexamers spaced by 6 base pairs, confers an efficient transactivation by TRbeta1 but a poor transactivation by TRalpha1. While both receptors form heterodimers with RXR on MBPTRE, the poor transactivation by TRalpha1 correlates also with its ability to bind efficiently as a monomer. This monomer, which is only observed with TRalpha1 bound to MBPTRE, interacts neither with N-CoR nor with SRC-1, explaining its functional inefficacy. However, in Xenopus oocytes, in which RXR proteins are not detectable, the transactivation mediated by TRalpha1 and TRbeta1 is equivalent and independent of a RXR supply, raising the question of the identity of the thyroid hormone receptor partner in these cells. Thus, in mammalian cells, the binding characteristics of TRalpha1 to MBPTRE (i.e. high monomer binding efficiency and low transactivation activity) might explain the particular pattern of T3 responsiveness of MBP gene expression during central nervous system development.

Long-term antiretroviral treatment initiated at primary HIV-1 infection affects the size, composition, and decay kinetics of the reservoir of HIV-1-infected CD4 T cells.

Initiation of antiretroviral therapy during the earliest stages of HIV-1 infection may limit the seeding of a long-lasting viral reservoir, but long-term effects of early antiretroviral treatment initiation remain unknown. Here, we analyzed immunological and virological characteristics of nine patients who started antiretroviral therapy at primary HIV-1 infection and remained on suppressive treatment for >10 years; patients with similar treatment duration but initiation of suppressive therapy during chronic HIV-1 infection served as controls. We observed that independently of the timing of treatment initiation, HIV-1 DNA in CD4 T cells decayed primarily during the initial 3 to 4 years of treatment. However, in patients who started antiretroviral therapy in early infection, this decay occurred faster and was more pronounced, leading to substantially lower levels of cell-associated HIV-1 DNA after long-term treatment. Despite this smaller size, the viral CD4 T cell reservoir in persons with early treatment initiation consisted more dominantly of the long-lasting central-memory and T memory stem cells. HIV-1-specific T cell responses remained continuously detectable during antiretroviral therapy, independently of the timing of treatment initiation. Together, these data suggest that early HIV-1 treatment initiation, even when continued for >10 years, is unlikely to lead to viral eradication, but the presence of low viral reservoirs and durable HIV-1 T cell responses may make such patients good candidates for future interventional studies aiming at HIV-1 eradication and cure. IMPORTANCE: Antiretroviral therapy can effectively suppress HIV-1 replication to undetectable levels; however, HIV-1 can persist despite treatment, and viral replication rapidly rebounds when treatment is discontinued. This is mainly due to the presence of latently infected CD4 T cells, which are not susceptible to antiretroviral drugs. Starting treatment in the earliest stages of HIV-1 infection can limit the number of these latently infected cells, raising the possibility that these viral reservoirs are naturally eliminated if suppressive antiretroviral treatment is continued for extremely long periods of time. Here, we analyzed nine patients who started on antiretroviral therapy within the earliest weeks of the disease and continued treatment for more than 10 years. Our data show that early treatment accelerated the decay of infected CD4 T cells and led to very low residual levels of detectable HIV-1 after long-term therapy, levels that were otherwise detectable in patients who are able to maintain a spontaneous, drug-free control of HIV-1 replication. Thus, long-term antiretroviral treatment started during early infection cannot eliminate HIV-1, but the reduced reservoirs of HIV-1 infected cells in such patients may increase their chances to respond to clinical interventions aiming at inducing a drug-free remission of HIV-1 infection.

Hiiliteräspalkin kuitulaserhitsaus

Hitsaavassa teollisuudessa kilpailukyvyn säilyttäminen ja mahdollinen parantaminen edellyttää hitsauksen tehokkuuden nostoa. Laserhitsauksen nopeus, tarkkuus, tasainen laatu ja aikaansaatava syvä tunkeuma ovatkin vakiinnuttaneet menetelmän vankan aseman tehokkaana valmistusmenetelmänä. Sähkön ja heliumin hinnan nousu ovat pakottaneet teollisuuden miettimään entistä tehokkaampien ja ympäristöystävällisempien laserlähteiden hankkimista. Kuitulaserin korkea hyötysuhde, hyvä säteenlaatu, suuri teho ja matalat käyttökustannukset ovat herättäneet kiinnostusta laserhitsaavassa teollisuudessa. Diplomityössä keskityttiin kuitulaserhitsauksen soveltamiseen. Työn tavoitteena oli parantaa kuitulaserhitsausmenetelmän ymmärrystä ja saada käsitys siitä, miten valitaan hitsausparametrien arvot, ja soveltuuko kuitulaser teolliseen tuotantoon. Tutkimuksessa pyrittiin löytämään peruskokeilla optimaaliset hitsausparametrit, joilla syntyy hyvin tunkeutunut, vähän huokosia sisältävä, ja ulkoisesti laadukas hitsi, sekä optimaalinen hitsin tunkeumaprofiili. Lopuksi hitsausparametreja testattiin tuotteen hitsauksessa. Kuitulaser soveltuu erinomaisesti hiiliteräksen hitsaukseen ja hyvin erikoislujien terästen hitsaukseen, kun teräksen hiili- ja rikkipitoisuudet ovat matalia. Sillä on laaja parametrialue. Yleisimmät hitsausvirheet ovat vajaa hitsautumissyvyys ja huokoset. Tässä diplomityössä keskityttiin etsimään yhdelle valmistettavalle tuotteelle optimaaliset kuitulaserhitsausparametrit. Kuitulaserin laser- ja prosessiparametrien vaikutusta hitsiin ei ole juurikaan tutkittu. Diplomityön kokeiden perusteella olisi hyvä tehdä eri materiaalien jatkotutkimusta railonvalmistuksen, kuten liitoksen oksidikerroksen ja ilmaraon sekä suojakaasun, vaikutuksesta hitsiin. Kuitulaserin hyvä säteenlaatu ja muut laser-parametrit ovat tuoneet mukanaan prosessiin uusia ilmiöitä, joita on syytä tutkia lisää.

The double-edged sword of social capital: Three essays on entrepreneurship in developing nations

ABSTRACT My study seeks to answer the main question: "how does entrepreneurs' social capital positively and negatively affect their resource mobilization efforts, and exploitation of entrepreneurial opportunity?" To answer this question, I develop a model for examining positive and negative effects of social capital on resource accumulation by entrepreneurs, and the subsequent effect of resource accumulation on the exploitation of entrepreneurial opportunity, and utilize data from Africa to ëmpirically test the relationships in this model. Developing nations are a suitable context because: a) They require entrepreneurship for economic development, b) They have received less attention in management and entrepreneurship research, c) Because of inadequately-developed institutions, entrepreneurs from developing nations face major resource mobilization challenges hence they often turn to their social ties for resources, and d) The communalistic and collectivistic nature of most developing nations -encouraging support and sharing of resources- may help us better understand how society's values and structures may contribute and also deduct firm resources. My study reveals that social capital contributes resources to entrepreneurs in developing nations at a cost that takes away resources, and that more resources but lower costs facilitate entrepreneurial opportunity exploitation. For entrepreneurs in developing nations, large networks, greater shared identity, and more trust are beneficial. To increase chances of raising more resources, entrepreneurs from communalistic societies should include network members from outside their communities. Besides providing financial support, policy-makers should develop training programs and advisory services on configuration of entrepreneurs' networks so as to achieve more resources at a low cost. My study insights can help improve entrepreneurs' resource accumulation efforts and the subsequent growth of their firms, leading to the overall economic growth of developing nations.

The Dynamic Analysis of a Human Skeleton Using the Flexile Multibody Simulation Approach

The human motion study, which relies on mathematical and computational models ingeneral, and multibody dynamic biomechanical models in particular, has become asubject of many recent researches. The human body model can be applied to different physical exercises and many important results such as muscle forces, which are difficult to be measured through practical experiments, can be obtained easily. In the work, human skeletal lower limb model consisting of three bodies in build using the flexible multibody dynamics simulation approach. The floating frame of reference formulation is used to account for the flexibility in the bones of the human lower limb model. The main reason of considering the flexibility inthe human bones is to measure the strains in the bone result from different physical exercises. It has been perceived the bone under strain will become stronger in order to cope with the exercise. On the other hand, the bone strength is considered and important factors in reducing the bone fractures. The simulation approach and model developed in this work are used to measure the bone strain results from applying raising the sole of the foot exercise. The simulation results are compared to the results available in literature. The comparison shows goof agreement. This study sheds the light on the importance of using the flexible multibody dynamic simulation approach to build human biomechanical models, which can be used in developing some exercises to achieve the optimalbone strength.

Jyväskylän kaukolämpöverkon kehittäminen

Kaukolämmitys on yleisin Suomessa käytetty lämmitysmuoto ja sen osuus koko lämmitysmarkkinoista on noin 50 %. Kaukolämmön varsinainen tuotanto ja jakelu alkoivat Suomessa vuonna 1957 ja Jyväskylässä vuonna 1960. Jyväskylässä kaukolämmön piiriin kuuluivuoden 2006 loppuun mennessä noin 3200 asiakasta. Suurin tuntiteho laitoksilta oli noin 375 MW. Vuonna 2020 suurimman tuntitehon on ennustettu olevan noin 480 MW, mikä tarkoittaa asiakasmäärän ja verkon pituuden merkittävää kasvua. Jyväskylän kaukolämpöverkon nykytilanne on hyvä. Verkostolaskennan tulosten perusteella lämpö saadaan siirtymään nykyisillä laitoksilla ja verkon laitteilla jokaiselle asiakkaalle niin normaalitilanteessa kuin päälaitoksen häiriötilanteessa. Häiriötilanteessa paikallisia ongelmia voi esiintyä, mutta niihin voidaan vaikuttaa parantavasti esimerkiksi verkon staattisen paineen nostolla. Jyväskylän kaukolämpöverkon tulevaisuuden näkymät ovat erinomaiset. Laskennan perusteella verkkoa voidaan laajentaa kaikille laskennassa mukana olleille alueille ilman suurempia ongelmia. Uuden tuotantokapasiteetin, verkonlaajentumisen ja asiakasmäärän kasvun aiheuttamat kehitystarpeet saatiin selvitetyksi ja tulokset olivat aikaisempien tutkimusten suuntaisia. Tulevaisuutta ajatellen verkkoon joudutaan tekemään muutamia muutoksia suunniteltujen uusien yhteyksien lisäksi. Uuteen linjaan, joka yhdistää Palokan verkon toisen yhteyden kautta Jyväskylän pääverkkoon, rakennetaan mahdollisesti pumppaamo. Lisäkuristusventtiilejä tarvitaan viiteen eri paikkaan turvaamaan riittävän suuret kaukolämpöveden paluupaineet. Osa venttiileistä olisi suositeltavaa asentaa jo nykytilanteessa, sillä niiden hankinta parantaisi verkon nykytilaa.
