INTAKE VARIABLES AS PREDICTORS OF ASSESSMENT AND REFERRAL PROCEDURE OUTCOMES IN EMPLOYEE ASSISTANCE PROGRAMS

While reported prevalence rates of troubled employees vary considerably, even conservative estimates indicate a major public health problem. For example, alcohol and drug related problems alone cost U.S. industry more than 45 billion dollars annually.^ Of the alternatives available to deal with these problems, e.g., dismissal or disciplinary actions, the most viable and cost effective are employee assistance programs (EAP), designed to provide professional assistance to employees experiencing alcohol, drug, emotional or personal crisis.^ The principal component of an EAP is that of assessment and referral, and this study was developed to determine which EAP client intake variables are the most efficacious predictors of assessment and referral procedures.^ Although, specific client intake variables were statistically significant the discriminant classification analysis was demonstrably inadequate. Nevertheless, the identification of A/R procedure phases which were not efficacious, as well as EAP client populations for whom services were not effective, were extremely valuable discernments. Identifying the less efficacious components of the A/R process provided an opportunity to recommend alternatives to current program procedures and practices, which may ameliorate program effectiveness. ^

EVIDENCE OF HUMAN ENDOGENOUS RETROVIRUS K INVOLVEMENT IN HUMAN CANCER

Many lines of clinical and experimental evidence indicate a viral role in carcinogenesis (1-6). Our access to patient plasma, serum, and tissue samples from invasive breast cancer (N=19), ductal carcinoma in situ (N=13), malignant ovarian cancer (N=12), and benign ovarian tumors (N=9), via IRB-approved and informed consent protocols through M.D. Anderson Cancer Center, as well as normal donor plasmas purchased from Gulf Coast Regional Blood Center (N=6), has allowed us to survey primary patient blood and tissue samples, healthy donor blood from the general population, as well as commercially available human cell lines for the presence of human endogenous retrovirus K (HERV-K) Env viral RNA (vRNA), protein, and viral particles. We hypothesize that HERV-K proteins are tumor-associated antigens and as such can be profiled and targeted in patients for diagnostic and therapeutic purposes. To test this hypothesis, we employed isopycnic ultracentrifugation, a microplate-based reverse transcriptase enzyme activity assay, reverse transcription – polymerase chain reaction (RT-PCR), cDNA sequencing, SDS-PAGE and western blotting, immunofluorescent staining, confocal microscopy, and transmission electron microscopy to evaluate v HERV-K activation in cancer. Data from large numbers of patients tested by reverse transcriptase activity assay were analyzed statistically by t-test to determine the potential use of this assay as a diagnostic tool for cancer. Significant reverse transcriptase enzyme activity was detected in 75% of ovarian cancer patients, 53.8% of ductal carcinoma in situ patient, and 42.1% of invasive breast cancer patient samples. Only 11.1% of benign ovarian patient and 16.7% of normal donor samples tested positive. HERV-K Env vRNA, or Env SU were detected in the majority of cancer types screened, as demonstrated by the results shown herein, and were largely absent in normal controls. These findings support our hypothesis that the presence of HERV-K in patient blood circulation is an indicator of cancer or pre-malignancy in vivo, that the presence of HERV-K Env on tumor cell surfaces is indicative of malignant phenotype, and that HERV-K Env is a tumor-associated antigen useful not only as a diagnostic screening tool to predict patient disease status, but also as an exploitable therapeutic target for various novel antibody-based immunotherapies.

Booster Breaks in the workplace: Effects on employee stress

The current study examined the effects of a 15-minute daily physical activity break on the stress levels of white collar employees. An innovative group physical activity program, the Booster Break, was implemented in two worksites, both located in a large metropolitan area. One hundred sixteen participants were randomly assigned to one of three conditions; 43 participants were assigned to the Booster Break condition, 40 participants were assigned to an individual, computer-based physical activity condition, and 32 were assigned to a no-physical activity control condition. Self-report and objective measures were taken at baseline and after the completion of the intervention. There were no significant differences among conditions in perceived stress or blood pressure after the intervention. However, the data showed trends in the direction predicted with a decrease in perceived stress among Booster Break (change in perceived stress = -0.1) and computer prompt participants (change in perceived stress = -0.2) and an increase in perceived stress among the control group (change in perceived stress = 0.2). More research is recommended to fully understand the effects of worksite physical activity on stress.^

Involvement of {\it p53\/} in PUVA-induced skin cancers

A combination of psoralen and ultraviolet-A radiation, commonly referred to as "PUVA," is widely used in the treatment of psoriasis. However, PUVA treatment increases the risk of developing skin cancer in psoriasis patients and induces skin cancer in mice. It is, however unknown whether the increased incidence of skin cancer in PUVA treated psoriasis patients is due to the carcinogenic effects of PUVA therapy or due to an indirect effect such as immunosuppression, which can permit the growth of tumors induced by UVB radiation. In this study, we used the p53 tumor suppressor gene as a molecular marker to determine whether PUVA-induced mouse skin cancers contain unique mutations in p53 that are different from UV-induced mutations, and if so, determine whether skin cancers from PUVA treated patients have PUVA-type or UV-type p53 mutations. Since the DNA lesions induced by PUVA are quite different from those induced by UV, we hypothesize that p53 mutations induced by PUVA may also be different from those induced by UV.^ Analysis of PUVA-induced murine skin cancers for p53 mutations revealed that 14 of 15 (93%) missense mutations detected in these cancers were localized at 5$\sp\prime$-TA/5$\sp\prime$-TAT sites, potential sites of psoralen photoadditions. Mutations at these sequences are exceedingly rare in UV-induced murine skin cancers. In addition, PUVA-induced murine skin cancers did not contain UV signature (C $\to$ T or CC $\to$ TT transitions) mutations in p53. These results suggest that PUVA induces unique mutations in p53 that can be distinguished from those induced by UV.^ Next we determined whether SCCs arising in PUVA treated psoriasis patients have PUVA-type or UV-type p53 mutations. The results indicated that 16 of 25 (64%) missense p53 mutations detected in SCCs from PUVA treated patients were located at 5$\sp\prime$-TG, 5$\sp\prime$-TA and 5$\sp\prime$-TT sites, putative sites of psoralen photobinding. Interestingly, about 32% of p53 mutations detected in SCCs from PUVA treated patients had the UV signature. Taken together these results suggest that both PUVA and UVB play a role in the development of SCCs in psoriasis patients undergoing PUVA therapy. ^

Participatory modeling for sustainable development in water and agrarian systems: potential and limits of stakeholder involvement

Public participation is increasingly advocated as a necessary feature of natural resources management. The EU Water Framework Directive (WFD) is such an example, as it prescribes participatory processes as necessary features in basin management plans (EC 2000). The rationale behind this mandate is that involving interest groups ideally yields higher-quality decisions, which are arguably more likely to meet public acceptance (Pahl-Wostl, 2006). Furthermore, failing to involve stakeholders in policy-making might hamper the implementation of management initiatives, as controversial decisions can lead pressure lobbies to generate public opposition (Giordano et al. 2005, Mouratiadou and Moran 2007).

Social involvement for community development in rural areas of Cuenca, Spain

Community development must be accompanied by a social involvement process which creates functional groups of citizens capable of taking responsibility for their own development. It is important that this process promotes the structuring of all population groups and provides the appropriate institutional and technical support. The present paper addresses these issues based on over 25 years of experience by the Association Instituto de Desarrollo Comunitario de Cuenca in revitalizing rural areas of the Spanish province of Cuenca. This paper analyses the social involvement process encouraged by this association, the relationships between public institutions and local associations, the role of these associations and the difficulties encountered in the rural areas. The long-term perspective of this experience provides some keys which can be used to successfully support the process of social involvement ―such as information on its characteristics and methodological tools―, establish local associations and create sustainable partnerships that foster the growth of leadership within the community development process.

The involvement of thaumatin-like proteins in plant food cross-reactivity: a multicenter study using a specific protein microarray.

Cross-reactivity of plant foods is an important phenomenon in allergy, with geographical variations with respect to the number and prevalence of the allergens involved in this process, whose complexity requires detailed studies. We have addressed the role of thaumatin-like proteins (TLPs) in cross-reactivity between fruit and pollen allergies. A representative panel of 16 purified TLPs was printed onto an allergen microarray. The proteins selected belonged to the sources most frequently associated with peach allergy in representative regions of Spain. Sera from two groups of well characterized patients, one with allergy to Rosaceae fruit (FAG) and another against pollens but tolerant to food-plant allergens (PAG), were obtained from seven geographical areas with different environmental pollen profiles. Cross-reactivity between members of this family was demonstrated by inhibition assays. Only 6 out of 16 purified TLPs showed noticeable allergenic activity in the studied populations. Pru p 2.0201, the peach TLP (41%), chestnut TLP (24%) and plane pollen TLP (22%) proved to be allergens of probable relevance to fruit allergy, being mainly associated with pollen sensitization, and strongly linked to specific geographical areas such as Barcelona, Bilbao, the Canary Islands and Madrid. The patients exhibited mayor que50% positive response to Pru p 2.0201 and to chestnut TLP in these specific areas. Therefore, their recognition patterns were associated with the geographical area, suggesting a role for pollen in the sensitization of these allergens. Finally, the co-sensitizations of patients considering pairs of TLP allergens were analyzed by using the co-sensitization graph associated with an allergen microarray immunoassay. Our data indicate that TLPs are significant allergens in plant food allergy and should be considered when diagnosing and treating pollen-food allergy.

Lateral orbitofrontal cortex involvement in initial negative aesthetic impression formation

It is well established that aesthetic appreciation is related with activity in several different brain regions. The identification of the neural correlates of beauty or liking ratings has been the focus of most prior studies. Not much attention has been directed towards the fact that humans are surrounded by objects that lead them to experience aesthetic indifference or leave them with a negative aesthetic impression. Here we explore the neural substrate of such experiences. Given the neuroimaging techniques that have been used, little is known about the temporal features of such brain activity. By means of magnetoencephalography we registered the moment at which brain activity differed while participants viewed images they considered to be beautiful or not. Results show that the first differential activity appears between 300 and 400 ms after stimulus onset. During this period activity in right lateral orbitofrontal cortex (lOFC) was greater while participants rated visual stimuli as not beautiful than when they rated them as beautiful. We argue that this activity is associated with an initial negative aesthetic impression formation, driven by the relative hedonic value of stimuli regarded as not beautiful. Additionally, our results contribute to the understanding of the nature of the functional roles of the lOFC.

An approach to stakeholders involvement in the preparedness for nuclear and radiological emergency response & recovery in Spain

The elaboration of a generic decision-making strategy to address the evolution of an emergency situation, from the stages of response to recovery, and including a planning stage, can facilitate timely, effective and consistent decision making by the response organisations at every level within the emergency management structure and between countries, helping to ensure optimal protection of health, environment, and society. The degree of involvement of stakeholders in this process is a key strategic element for strengthening the local preparedness and response and can help a successful countermeasures strategy. A significant progress was made with the multi-national European project EURANOS (2004-2009) which brought together best practice, knowledge and technology to enhance the preparedness for Europe's response to any radiation emergency and long term contamination. The subsequent establishment of a European Technology Platform and the recent launch of the research project NERIS-TP ("Towards a self sustaining European Technology Platform (NERIS-TP) on Preparedness for Nuclear and Radiological Emergency Response and Recovery") are aimed to continue with the remaining tasks for gaining appropriate levels of emergency preparedness at local level in most European countries. One of the objectives of the NERIS-TP project is: Strengthen the preparedness at the local/national level by setting up dedicated fora and developing new tools or adapting the tools developed within the EURANOS projects (such as the governance framework for preparedness, the handbooks on countermeasures, the RODOS system, and the MOIRA DSS for long term contamination in catchments) to meet the needs of local communities. CIEMAT and UPM in close interaction with the Nuclear Safety Council will explore, within this project, the use and application in Spain of such technical tools, including other national tools and information and communication strategies to foster cooperation between local, national and international stakeholders. The aim is identify and involve relevant stakeholders in emergency preparedness to improve the development and implementation of appropriate protection strategies as part of the consequence management and the transition to recovery. In this paper, an overview of the "state of the art" on this area in Spain and the methodology and work Plan proposed by the Spanish group within the project NERIS to grow the stakeholder involvement in the preparedness to emergency response and recovery is presented.

CSR Policies: Effects on Labour Productivity in Spanish Micro and Small Manufacturing Companies

This paper analyses empirical evidence of efforts to enable Spanish micro and small manufacturing companies to boost their labour productivity rates through the development of the main pillars of their corporate social responsibility (CSR) policies. This study aims to develop new approaches and sensibilities towards work from an ethical, values (virtues) and CSR perspective, showing how internal dimensions of CSR, such those related to relationships with employees and responsibility in processes and product quality, can improve labour performance and labour efficiency, thereby contributing to a better society. The results of a sample of 929 small businesses indicate that the social responsibility policies that most contributed to a short-term increase in labour productivity are those related to internal aspects of the company, in particular its involvement in the quality of processes and products, promotion of innovation and employee care. However, the impact on labour productivity of CSR policies related to external factors, such as relationship with stakeholders and environmental concern, could not be empirically proven in this paper.

BEM-ESTAR NO TRABALHO: O IMPACTO DOS VALORES ORGANIZACIONAIS, PERCEPÇÃO DE SUPORTE ORGANIZACIONAL E PERCEPÇÕES DE JUSTIÇA

A complexidade crescente no ambiente de trabalho tem exigido capacidade de adaptação dos empregados, com papéis exigindo maior flexibilidade e criatividade para superar os desafios que se apresentam. Ciclos de vida de produtos cada vez menores num mercado muito agressivo têm acarretado enormes pressões nos empregados, com efeitos colaterais na saúde, como estresse e doenças psicossomáticas. O tratamento de doenças, embora relevante para minimizar o sofrimento humano, não tem sido suficiente para dar respostas desejadas neste ambiente de trabalho numa concepção de saúde que abranja o bem-estar e que permita aos empregados enfrentar melhor os desafios que se apresentam. O campo da psicologia positiva, voltada ao estudo dos fatores que propiciam o florescimento das pessoas, permite às organizações, gestores e empregados ampliar o leque de alternativas possíveis para melhorar a saúde das pessoas, com reflexos positivos para as organizações. O objetivo deste estudo visou a confirmar se os valores organizacionais, percepção de suporte organizacional e percepções de justiça (distributiva e de procedimentos) são antecedentes de bem-estar no trabalho, um construto composto das variáveis de satisfação no trabalho, envolvimento com o trabalho, e comprometimento organizacional afetivo. A amostra envolveu 404 trabalhadores atuando em empresas na região da Grande São Paulo, sendo 209 do sexo masculino e 193 do sexo feminino. Dividiu-se a amostra a partir de dois agrupamentos de empresas, o setor financeiro (compreendendo uma empresa com 243 respondentes) e o setor não financeiro (compreendendo 13 empresas com um total de 161 respondentes). Como instrumento para coleta de dados utilizou-se de um questionário composto de sete escalas, abrangendo as três variáveis de bem-estar no trabalho e as quatro variáveis independentes estudadas como seus antecedentes. Os resultados deste estudo, nos dois setores estudados, confirmaram que a percepção de suporte organizacional e a percepção de justiça distributiva acarretam maior satisfação no trabalho. A justiça de procedimentos também mostrou capacidade preditiva de satisfação no trabalho para o setor financeiro. O valor organizacional autonomia confirmou-se como antecedente de envolvimento com o trabalho nos dois setores. O valor organizacional realização e a percepção de justiça de procedimentos posicionaram-se como antecedentes de comprometimento organizacional afetivo para os setores não financeiro e financeiro, respectivamente. O valor organizacional preocupação com a coletividade e a percepção de suporte organizacional mostraram capacidade preditiva de comprometimento organizacional afetivo para os setores financeiro e não financeiro, respectivamente. Os resultados revelam que se promove o bem-estar no trabalho quando, nas organizações, se adotam políticas e práticas que dêem suporte e tratamento digno aos empregados, reforçando valores organizacionais que promovam um ambiente propício à inovação e à criatividade, com maior autonomia, onde os gestores valorizam a competência e o sucesso dos trabalhadores, e onde se predomina a honestidade e a sinceridade nas relações entre as pessoas e a organização. Os empregados tenderão a desenvolver transações típicas das trocas sociais, investindo seus esforços para a organização, com base na confiança e na lealdade.

Dissociation of cytokine-induced phosphorylation of Bad and activation of PKB/akt: Involvement of MEK upstream of Bad phosphorylation

The phosphatidylinositol 3-kinase (PI3K)-signaling pathway has emerged as an important component of cytokine-mediated survival of hemopoietic cells. Recently, the protein kinase PKB/akt (referred to here as PKB) has been identified as a downstream target of PI3K necessary for survival. PKB has also been implicated in the phosphorylation of Bad, potentially linking the survival effects of cytokines with the Bcl-2 family. We have shown that granulocyte/macrophage colony-stimulating factor (GM-CSF) maintains survival in the absence of PI3K activity, and we now show that when PKB activation is also completely blocked, GM-CSF is still able to stimulate phosphorylation of Bad. Interleukin 3 (IL-3), on the other hand, requires PI3K for survival, and blocking PI3K partially inhibited Bad phosphorylation. IL-4, unique among the cytokines in that it lacks the ability to activate the p21ras–mitogen-activated protein kinase (MAPK) cascade, was found to activate PKB and promote cell survival, but it did not stimulate Bad phosphorylation. Finally, although our data suggest that the MAPK pathway is not required for inhibition of apoptosis, we provide evidence that phosphorylation of Bad may be occurring via a MAPK/ERK kinase (MEK)-dependent pathway. Together, these results demonstrate that although PI3K may contribute to phosphorylation of Bad in some instances, there is at least one other PI3K-independent pathway involved, possibly via activation of MEK. Our data also suggest that although phosphorylation of Bad may be one means by which cytokines can inhibit apoptosis, it may be neither sufficient nor necessary for the survival effect.

Molecular cloning of a family of xenobiotic-inducible drosophilid cytochrome P450s: Evidence for involvement in host-plant allelochemical resistance

Cytochrome P450s constitute a superfamily of genes encoding mostly microsomal hemoproteins that play a dominant role in the metabolism of a wide variety of both endogenous and foreign compounds. In insects, xenobiotic metabolism (i.e., metabolism of insecticides and toxic natural plant compounds) is known to involve members of the CYP6 family of cytochrome P450s. Use of a 3′ RACE (rapid amplification of cDNA ends) strategy with a degenerate primer based on the conserved cytochrome P450 heme-binding decapeptide loop resulted in the amplification of four cDNA sequences representing another family of cytochrome P450 genes (CYP28) from two species of isoquinoline alkaloid-resistant Drosophila and the cosmopolitan species Drosophila hydei. The CYP28 family forms a monophyletic clade with strong regional homologies to the vertebrate CYP3 family and the insect CYP6 family (both of which are involved in xenobiotic metabolism) and to the insect CYP9 family (of unknown function). Induction of mRNA levels for three of the CYP28 cytochrome P450s by toxic host-plant allelochemicals (up to 11.5-fold) and phenobarbital (up to 49-fold) corroborates previous in vitro metabolism studies and suggests a potentially important role for the CYP28 family in determining patterns of insect–host-plant relationships through xenobiotic detoxification.
