Environmental strategies and green product development: an overview on sustainability‐driven companies
Authors: Albino Vito , Balice Azzurra , Dangelico Rosa Maria 
Published: January 2009

AbstractTo respond effectively and efficiently to the environmental sustainability challenge, an important role can be played by companies, through appropriate strategies and operations, such as green processes and product development. In this paper, we investigate whether the development of green products is supported by the environmental strategic approaches adopted by sustainability‐driven companies, and whether there are economic sector or geographical area specificities. To this purpose, first we develop a taxonomy of environmental strategies and we define measurable proxies for both the environmental strategic approaches identified and the green product development. Then, we study a sample represented by the companies included in the Dow Jones Sustainability World Index (DJSWI). The methodology used is based on the content analysis of companies' websites and relevant documents, such as environmental and sustainability reports. The main result is that the levels of adoption of different environmental strategic approaches are higher for green product developers than for green product non‐developers. Moreover, the most implemented strategic approaches for green product developers vary depending on the economic sector, while a more homogeneous behaviour is found from the geographical perspective.

National culture, regulation and country interaction effects on the association of environmental management systems with environmentally beneficial innovation
Authors: Wagner Marcus 
Published: January 2009

AbstractI address in a comparative perspective the question of whether environmental management systems and particular managerial activities to reduce negative environmental impacts have a positive influence on the probability of firms carrying out environmental innovations. Based on binary and multinomial discrete choice models, I study the relationship of a number of determinants to the occurrence of environmental innovations based on data from a survey carried out in 2001 in nine European states. I find evidence that environmental management systems are associated with process innovations, but that this is moderated by the interaction of environmental management system implementation with country location. I do not find that environmental management systems are associated with product innovations or that a moderating effect of country location exists. County‐specific national cultures and regulatory regimes moderate the association of environmental management system implementation with environmental product and process innovations, respectively.

Authors: Yan Bo , Chen Yi‐Yun , Gui Shou‐Ping 
Published: January 2009

AbstractWith analysis on the necessity and functions of the equipments sharing platform and the cooperative work system for colleges and universities, this paper designs the cooperative work system to provide cooperative support for resource query and reservation. The system classifies users' resource application roles, divides users' application information into different cooperative grades, and provides a basis for users' cooperative work. Functions, authorization, page flow, operating methods, and relevant database table of cooperative roles are shown in detail. At the same time, the ASP system will be introduced into the system, and a special fee management system will be established for effective management of the system. Functions and page flow of the fee management system are also designed. © 2009 Wiley Periodicals, Inc.

AbstractWhereas the cytostatic agents mer‐[RhX3(DMSO)(pp)] (X=Cl, Br; pp=phen, dpq) are considerably more potent than their facial isomers, this order is reversed for the analogous kinetically more inert IrIII polypyridyl complexes. The complexes induce specific apoptotic cell death in leukemia and lymphoma cells via the intrinsic mitochondrial pathway and cause negligible necrotic damage.magnified imageMeridional rhodium(III) polypyridyl complexes of the type mer‐[RhX3(DMSO)(pp)] (X=Cl, pp=phen 1, dpq 2, dppz 3; X=Br, pp=phen 4) represent a promising class of potent cytostatic agents for the treatment of lymphoma and leukemia. Exposure of their DMSO solutions to light leads to slow isomerization to mixtures of the mer and the generally less active fac isomers. As a result, the IC50 values of 1 and 2 toward HT‐29 cells increase from 0.19 and 0.069 μM on immediate use in the dark to 0.66 and 0.312 μM, respectively, after exposure of their DMSO stock solutions to light for 7 days. In striking contrast, the complexes mer‐[IrX3(DMSO)(phen)] (X=Cl 7, Br 8) are significantly less cytotoxic than their facial IrIII polypyridyl counterparts: IC50=20.3 μM for 7 and 4.6 μM for fac‐[IrCl3(DMSO)(phen)] 5 toward MCF‐7 cells. The IC50 values for the complexes fac‐[IrX3(L)(pp)] 9–13 decrease in the orders: a) Cl>Br for X and b) H2O>DMSO for L. Specific apoptotic cell death by DNA fragmentation was detected for leukemia (NALM‐6) and lymphoma (BJAB) cells after incubation with 2, 3, and 11 (X=Br, L=H2O, pp=phen) for 72 h. Loss of the mitochondrial membrane potential in lymphoma cells indicates that apoptosis is mediated via the intrinsic mitochondrial pathway. LDH release assays after 1 or 3 h demonstrate that necrotic damage is negligible.

Published: January 2009

AbstractThe importance of imaging mass spectrometry (MS) for visualizing the spatial distribution of molecular species in biological tissues and cells is growing. We have developed a new system for imaging MS using MeV ion beams, termed MeV‐secondary ion mass spectrometry (MeV‐SIMS) here, and demonstrated more than 1000‐fold increase in molecular ion yield from a peptide sample (1154 Da), compared to keV ion irradiation. This significant enhancement of the molecular ion yield is attributed to electronic excitation induced in the near‐surface region by the impact of high energy ions. In addition, the secondary ion efficiency for biologically important compounds (>1 kDa) increased to more than 1010 cm−2, demonstrating that the current technique could, in principle, achieve micrometer lateral resolution. In addition to MeV‐SIMS, peptide compounds were also analyzed with cluster‐SIMS and the results indicated that in the former method the molecular ion yields increased substantially compared to the latter. To assess the capability of MeV‐SIMS to acquire heavy‐ion images, we have prepared a micropatterned peptide surface and successfully obtained mass spectrometric imaging of the deprotonated peptides (m/z 1153) without any matrix enhancement. The results obtained in this study indicate that the MeV‐SIMS technique can be a powerful tool for high‐resolution imaging in the mass range from 100 to over 1000 Da.

Characterisation of the phenolic and flavonoid fractions and antioxidant power of Italian honeys of different botanical origin
Authors: Pichichero Elena , Canuti Lorena , Canini Antonella 
Published: January 2009

AbstractBACKGROUND: Twenty‐seven Italian honey samples of different floral origin were analysed for total phenolic and flavonoid contents by a spectrophotometric method and for antioxidant power and radical‐scavenging activity by the ferric‐reducing/antioxidant power (FRAP) and 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) assays respectively. In addition, the phenolic and flavonoid profiles were analysed using high‐performance liquid chromatography with UV detection (HPLC‐UV).RESULTS: The results of this study showed that honey contains copious amounts of phenolics and flavonoids. HPLC‐UV analysis showed a similar qualitative polyphenolic profile for all honey samples analysed. The main difference among samples was in the contribution of individual analytes, which was affected by floral origin. Total phenolic and flavonoid contents varied from 60.50 to 276.04 mg gallic acid equivalent kg−1 and from 41.88 to 211.68 mg quercetin equivalent kg−1 respectively. The antioxidant capacity was high and differed widely among samples. The FRAP value varied from 1.265 to 4.396 mmol Fe2+ kg−1, while the radical‐scavenging activity expressed as DPPH‐IC50 varied from 7.08 to 64.09 mg mL−1. Correlations between the parameters analysed were found to be statistically significant (P < 0.05).CONCLUSION: The present study shows that honey contains high levels of phenolics and flavonoids and that the distribution of these compounds is influenced by the honey's floral origin.

Does brand social power mean market might? Exploring the influence of brand social power on brand evaluations
Authors: Crosno Jody L. , Freling Traci H. , Skinner Steven J. 
Published: January 2009

AbstractThe importance of brand equity has been recognized in the marketing literature for years. Although researchers generally agree there is a social component to brand equity, empirical work in this area stops short of exploring the brand's ability to exert a social influence on consumers and their choices. The present manuscript attempts to address this deficit and extend the brand equity literature by proposing a new construct—brand social power. Drawing from research on social influence and perceived power, five bases of brand social power are identified and a conceptual attempt is made to integrate brand social power with existing brand equity frameworks. The impact of brand social power is also examined empirically at the level of individual power bases, for overall brand social power, and in terms of brand equity. © 2009 Wiley Periodicals, Inc.

Published: January 2009

AbstractTo revalidate the Freezing of Gait Questionnaire (FOG‐Q), patients with Parkinson's disease (PD) were randomly assigned to receive rasagiline (1 mg/day) (n = 150), entacapone (200 mg with each dose of levodopa) (n = 150), or placebo (n = 154). Patients were assessed at baseline and after 10 weeks using the FOG‐Q, Unified Parkinson's Disease Rating Scale (UPDRS), Beck Depression Inventory (BDI), and Parkinson's Disease Questionnaire (PDQ‐39). FOG‐Q dimensionality, test–retest reliability, and internal reliability were examined. Convergent and divergent validities were assessed by correlating FOG‐Q with UPDRS, BDI, and PDQ‐39. Comparisons between FOG‐Q item 3 and UPDRS item 14 were also made. Principal component analysis indicated that FOG‐Q measures a single dimension. Test–retest reliability and internal reliability of FOG‐Q score was high. FOG‐Q was best correlated to items of the UPDRS relating to walking, general motor issues, and mobility. Correlations between baseline and endpoint suggested that FOG‐Q item 3 is at least as reliable as UPDRS item 14. At baseline, 85.9% of patients were identified as “Freezers” using FOG‐Q item 3 (≥1) and 44.1% using UPDRS item 14 (≥1) (P < 0.001). FOG‐Q was a reliable tool for the assessment of treatment intervention. FOG‐Q item 3 was effective as a screening question for the presence of FOG. © 2007 Movement Disorder Society

AbstractA role of ATP13A2 in early‐onset Parkinsonism (EOP) has been proposed. Conversely, the contribution of this ATPase to late‐onset Parkinson's disease (PD) remains unexplored. We therefore conducted a case–control association study in this age‐of‐onset group with PD. The initial sample was of German origin and consisted of 220 patients with late‐onset PD (mean age of onset 60.1 years) and 232 age‐matched unrelated controls. Five single nucleotide polymorphisms (SNPs) covering ATP13A2 and its common haplotypes were genotyped. The overall association results in this sample were negative. Interestingly, gender stratification gave a positive result for SNP rs11203280 (PUNC = 0.016) in men. This result could not be reproduced in a replication sample of German and Serbian origin composed of 161 patients with late‐onset PD (mean age of onset 51.7 years) and 150 age‐ and ethnic‐matched controls. In conclusion, we found no consistent evidence for an association between ATP13A2 and late‐onset PD. © 2008 Movement Disorder Society
Improved asymmetry of gait in Parkinson's disease with DBS: Gait and postural instability in Parkinson's disease treated with bilateral deep brain stimulation in the subthalamic nucleus
Authors: Johnsen Erik L. , Mogensen Poul H. , Sunde Niels Aa. , Østergaard Karen 
Published: December 2008

AbstractPostural instability is a sign of progression of Parkinson's disease (PD) and often resistant to levodopa treatment. To explore the effect of bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) on postural stability and gait, full body gait analyses were performed without medication, OFF and ON DBS in eight PD patients and 12 healthy age‐matched controls. DBS setting was changed at least 3 hours before gait analysis. To describe asymmetry most and least affected sides (MAS and LAS) were rated with the Unified Parkinson's Disease Rating Scale, motor part and quantitative gait analysis with the Vicon 612 gait analysis system. Stride length and gait velocity but not cadence improved ON DBS. The distances between the heel markers and center of mass (COM) were asymmetric and reduced OFF DBS. STN DBS increased the distances significantly and reduced asymmetry. The improvement in heel to COM distance was larger on the MAS compared with the LAS. OFF DBS knee momentum asymmetry was inversed so that LAS was more impaired than MAS. ON DBS asymmetry improved. PD patients OFF DBS place the heel too close to COM. The most affected body side has the most impaired swing and the result is a smaller knee moment on the opposite and least affected body side and an asymmetric gait pattern with disturbed balance OFF STN DBS. The asymmetry OFF DBS improved ON DBS. We suggest that DBS facilitates symmetric gait and thereby improves balance during gait. © 2008 Movement Disorder Society
Speciation of Zn‐aminopolycarboxylic complexes by electrospray ionization mass spectrometry and ion chromatography with inductively coupled plasma mass spectrometry
Authors: Chen ZuLiang , Owen Gary , Megharaj Mallavarapu , Naidu Ravendra 
Published: January 2009

AbstractThe speciation of Zn‐aminopolycarboxylic complexes was investigated using both electrospray ionization mass spectrometry (ESI‐MS) and ion chromatography (IC) with inductively coupled plasma mass spectrometry (ICP‐MS). The resulting ESI mass spectra indicated that [Zn(HEDTA)]1−, [Zn(NTA)]1−, [Zn(EDTA)]2− and [Zn(DTPA)]3− were all simultaneously detected in solution; [Zn(NTA)]1− exhibited the weakest intensity of all these Zn‐aminopolycarboxylic complexes. IC/ICP‐MS was also successfully used to separate Zn complexes by anion‐exchange chromatography using a mobile phase containing 30 mM (NH4)2HPO4 at pH 7.5 giving reasonable resolution within 15 min. A weak peak attributable to the poor stability [Zn(NTA)]1− ion was also observed using IC/ICP‐MS. With the exception of [Zn(NTA)]1−, detection limits ranging from 0.5 to 1.0 µg/L were obtained and the proposed method was used for the determination of Zn aminopolycarboxylic complexes in soil solution.

Income Volatility and Psychological Depression
Authors: Prause JoAnn , Dooley David , Huh Jimi 
Published: January 2009

AbstractIncome volatility appears to be increasing especially among lower income workers. Such volatility may reflect the ongoing shift of economic risk from employers to employees as marked by decreasing job security and employer‐provided benefits. This study tests whether absolute volatility or downward volatility in income predict depression controlling for prior depression. A sample (n = 4,493) from the National Longitudinal Survey of Youth (NLSY79) with depression (CESD) measured at age 40 and prior depression measured eight to 10 years earlier was utilized. Downward volatility (frequency of income loss) was positively associated with depression; adjusting for downward volatility and other covariates, absolute volatility was negatively associated with depression. An interaction indicated a positive association between downward volatility and depression only when absolute volatility was high. These findings apply to respondents in a narrow age range (30 s) and the results warrant replication to identify the mediators linking absolute volatility and income loss to depression.
Community Action and Research as Citizenship Construction
Authors: Montero Maritza 
Published: January 2009

AbstractSocial change, well‐being and liberation have been intertwined in community research and action, as much as being used as political common‐places. In this paper, it is argued that community research and action can have a political character. The epistemological premises shared by both the community and political spheres are discussed, and concepts are defined. The way community psychological action can produce changes is illustrated by an experience carried out with children from poverty sectors of Caracas, Venezuela, intended to construct citizenship by developing awareness about values, civic rights and duties, while experiencing the advantages of participation, peaceful negotiation and solidarity, during art classes. Topics regarding citizenship values and ethics were painted and discussed in a participatory way. Results about how the children developed consciousness about those topics, relating them to their lives, are presented.

Published: January 2009

SummaryThe accumulation of seed mass in soybean is affected by both genotype and environment. The aim of the present study was to measure additive, epistatic and quantitative trait locus (QTL)×environment (QE) interaction effects of QTLs on the development of 100-seed weight in a population of 143 F5derived recombinant inbred lines (RILs) developed from the cross between the soybean cultivars ‘Charleston’ and ‘Dong Nong 594’. Broad-sense heritability of 100-seed weight from 30 days (30D) to 80D stages was 0·58, 0·52, 0·62, 0·60, 0·66 and 0·57, respectively. A total of 17 QTLs with conditional additive (a) effect and/or conditional additive×environment interaction (ae) effect at specific stages were identified in ten linkage groups by conditional mapping. Of them, only 4 QTLs had significantaeffect oraeeffect at different stages of seed development. Among QTLs with significantaeffect, five acted positively and six acted negatively on seed development. A total of 35 epistatic pairwise QTLs of 100-seed weight were identified by conditional mapping at different developmental stages. Five pairs of QTL showed the additive×additive epistatic (aa) effect and 16 QTLs showed theaa×environment interaction (aae) effect at the different developmental stages. QTLs withaaeffect as well with their environmental interaction effect appeared to vary at different developmental stages. Overall, the results indicated that 100-seed weight in soybean is under developmental, genetic and environmental control.
Phylogenetic relationships and genetic diversity of the USDAVignagermplasm collection revealed by gene-derived markers and sequencing

Published: January 2009

SummaryPhylogenetic relationships in the USDAVignagermplasm collection are somewhat unclear and their genetic diversity has not been measured empirically. To reveal interspecific phylogenetic relationships and assess their genetic diversity, 48 accessions representing 12Vignaspecies were selected, and 30 gene-derived markers from legumes were employed. Some high-quality amplicons were sequenced. Indels (insertion/deletions) were discovered from the sequence alignments that were specific identifiers for someVignaspecies. With regard to revealing polymorphisms, intron-spanning markers were more effective than exon-derived markers. These gene-derived markers were more successful in revealing interspecific polymorphisms than intraspecific polymorphisms at both the DNA fragment and sequence levels. Two different dendrograms were generated from DNA fragment data and sequence data, respectively. The results from these two dendrograms supported each other and showed similar phylogenetic relationships among theVignaspecies investigated. The accessions clustered into four main groups and 13 subgroups. Each subgroup represents a subgenus or a species. Phylogenetic analysis revealed that an accession might be misclassified in our collection. The putative misclassified accession was further supported by seed morphology. Limited intraspecific genetic diversity was revealed by these gene-derived markers and/or sequences. The USDAVignagermplasm collection currently consists of multiple species with many accessions further classified into specific subspecies, but very few subspecies of the total subspecies available exist within the collection. Based on our results, more attention should be paid to the subspecies, wild forms and/or botanical varieties for future curation in order to expand the genetic diversity ofVignagermplasm in the USDA collection.
