Barriers and enablers of digital extension services’ adoption among smallholder farmers: the case of Cambodia, the Philippines and Vietnam

Digital Extension Services (DES) could help smallholder farmers access science-based information to boost agricultural output and resource efficiency. Gaining insight into the factors influencing farmers' use of digital extension services was essential for executing behaviour change. A total of 937 farmers from Cambodia, the Philippines, and Vietnam were chosen as the sample for the study. This study employed the Theory of Planned Behaviour (TPB) framework by utilising a structural equation model. The findings showed a range of concerns pertaining to farmers' attitudes and actions regarding the use of digital extension services. Subjective norms, perceived behaviour control, and farmers' perceived usefulness had a favourable and significant impact on the uptake of digital extension services. Research has shown that both perceived risks and household wealth have a favourable impact on adoption rates. However, it is important to note that barriers and enablers differ throughout the three nations in Southeast Asia due to variations in culture, customs, norms, and socioeconomic factors. The paper presents a strategy to enhance farmers' engagement in DES technology by enhancing digital infrastructure, facilitating farmer access to hardware devices through government subsidies or private sector assistance, ensuring equitable access for women and youth, and organising additional training for key stakeholders

Development and Investment Plan for Automatic Traffic Safety Enforcement in the Regions of Southwest Finland and Satakunta in 2011–2015 – a Preliminary Study

I det här arbetet utformades en utvecklings- och investeringsplan för automatisk trafiksäkerhetsövervakning för åren 2011-2015 för landsvägsnätet i Egentliga Finland och Satakunta. Planen innehåller analys av den nuvarande verksamhetsmodellen och förslag hur verksamhetsmodellen kunde förbättras samt förslag om vilka vägavsnitt som ska få automatisk övervakning och vilka projekt som ska prioriteras under åren 2011-2015. Vidare beskrivs i planen den automatiska övervakningsteknik och verksamhetsmodell som används i Sverige samt åtgärdsförslag för att öka den automatiska trafikövervakningens acceptans. Den nuvarande verksamhetsmodellen och behovet av att utveckla den automatiska trafikövervakningen har utvärderats på basis av intervjuer med experter. Experterna ansåg att den nuvarande verksamhetsmodellen i huvudsak är funktionell och effektiv, eftersom man med relativt små kostnader har uppnått effektiva resultat. Den automatiska trafikövervakningen måste dock fortfarande utvecklas och Sveriges verksamhetsmodell ansågs vara en bra förebild och ett gott exempel. De viktigaste utvecklingsområdena ansågs vara utveckling av tekniken, snabbare informationsbehandling och automatisering, vilket skulle öka polisens resurser att verkställa övervakningen. Vägavsnitten som ska få automatisk övervakning under åren 2011-2015 prioriterades främst på basis av olycksfrekvens, antal olyckor, Tarva-beräkningsresultat, hastighetsdata och trafikmängder. Av olycksstatistiken har man främst uppmärksammat personskadeolyckor. Tarva-beräkningarna användes också för att utvärdera den automatiska trafikövervakningens inverkan och effektivitet. Enligt de intervjuade experterna är öppenhet kring övervakningen, synlig övervakningsapparatur och kontinuerlig informationsförmedling bland de viktigaste sätten att öka acceptansen. Genom att informera för man fram systemets fördelar och dess betydelse för trafiksäkerheten. Att förändra övervakningskamerans varumärke till säkerhetskamera enligt Sveriges modell ansågs även vara bra. I detta arbete presenteras en plan för att utveckla acceptansen för automatisk trafiksäkerhetsövervakning.Työssä laadittiin automaattisen liikenneturvallisuusvalvonnan kehittämis- ja investointisuunnitelma vuosille 2011-2015 Varsinais-Suomen ja Satakunnan maantieverkolle. Suunnitelmaan kuului nykyisen toimintamallin ja kehittämistarpeiden arviointi sekä vuosina 2011-2015 toteutettavien automaattivalvontajaksojen ja hankkeiden priorisointi. Lisäksi työssä kuvattiin Ruotsissa käytössä olevaa automaattivalvontatekniikkaa ja -toimintamallia sekä esitettiin toimenpide-ehdotuksia automaattivalvonnan hyväksyttävyyden lisäämiseksi. Nykyistä toimintamallia ja automaattivalvonnan kehittämistarpeita arvioitiin asiantuntijahaastattelujen perusteella. Asiantuntijat pitivät nykyistä toimintamallia pääasiassa toimivana ja tehokkaana, sillä suhteellisen pienillä kustannuksilla on päästy tehokkaisiin tuloksiin. Automaattivalvonnassa on kuitenkin asiantuntijoiden mielestä vielä kehitettävää ja Ruotsin toimintamallia pidettiin hyvänä suuntana ja esimerkkinä. Suurimpina kehittämiskohteina pidettiin tekniikan kehittämistä sekä tiedon käsittelyn nopeuttamista ja automatisointia, mikä lisäisi poliisin resursseja valvonnan suorittamiseen. Vuosina 2011-2015 toteutettavat automaattivalvotut tiejaksot priorisoitiin ensisijaisesti onnettomuustiheyksien, onnettomuusmäärien, Tarva-laskentatulosten, nopeustietojen ja liikennemäärien perusteella. Onnettomuustilastoista huomioitiin lähinnä henkilövahinkoon johtaneet onnettomuudet. Lisäksi Tarva-laskentatuloksia hyödynnettiin automaattivalvonnan vaikutusten ja tehokkuuden arvioinnissa. Haastateltujen asiantuntijoiden mielestä tärkeimmät keinot hyväksyttävyyden lisäämiseksi olivat valvonnan avoimuus, valvontalaitteiden näkyvyys ja jatkuva valvonnasta tiedottaminen. Tiedottamisella tuodaan esille järjestelmän hyödyt ja sen merkitys liikenteelle ja liikenneturvallisuuteen. Myös automaattivalvontakameran brändin muuttamista Ruotsin mallin mukaisesti turvallisuuskameraksi pidettiin hyvänä. Tässä työssä esitettiin suunnitelma automaattivalvonnan hyväksyttävyyden lisäämiseksi.The report contains a development and investment plan for automatic traffic safety enforcement in the road network of the regions of Southwest Finland and Satakunta for 2011–2015. The plan involved the assessment of the current operating model and development needs as well as the prioritisation of road sections chosen for automatic traffic safety enforcement and the projects to be implemented in 2011–2015. In addition, the report describes the technologies and the operating model used in automatic traffic safety enforcement in Sweden and presents proposals for action for increasing the level of public approval for automatic traffic safety enforcement. The current operating model and development needs in automatic traffic safety enforcement were assessed through expert interviews. The experts considered the current operating model to be, for the most part, functional and efficient, as relatively small investments have produced efficient results. The experts did, however, identify development needs in automatic traffic safety enforcement, and the Swedish model was perceived to offer useful direction and constitute a good example. The most significant development targets were considered to be the development of technology and the automation and speeding up of the processing of information, which would free up police resources for other tasks associated with traffic safety enforcement. The prioritisation of the road sections on which automatic traffic safety enforcement is to be implemented in 2011-2015 was carried out mainly based on accident frequencies, accident volumes, calculation results based on the Tarva system for the estimation of traffic safety effects, speed information and traffic volumes. In the review of accident statistics, mainly accidents leading death or injury were accounted for. In addition, the Tarva calculation results were utilised in estimating the effects and efficiency of automatic traffic safety enforcement. According to the experts interviewed, the most important ways to promote public approval of the system were openness in the implementation of enforcement, visibility of the enforcement equipment and informing citizens about the enforcement on a regular basis. Also, shifting the brand of the traffic enforcement camera more towards the notion of road safety camera in line with the Swedish model was considered a good idea. The report includes a plan for increasing public approval of automatic traffic safety enforcement

Biological and genetic interaction between Tenascin C and Neuropeptide S receptor 1 in allergic diseases

Neuropeptide S receptor 1 (NPSR1, GPRA 154, GPRA) has been verified as a susceptibility gene for asthma and related phenotypes. The ligand for NPSR1, Neuropeptide S (NPS), activates signalling through NPSR1 and microarray analysis has identified Tenascin C (TNC) as a target gene of NPS-NPSR1 signalling. TNC has previously been implicated as a risk gene for asthma. We aimed therefore to study the genetic association of TNC in asthma- and allergy-related disorders as well as the biological and genetic interactions between NPSR1 and TNC. Regulation of TNC was investigated using NPS stimulated NPSR1 transfected cells. We genotyped 12 TNC SNPs in the cross-sectional PARSIFAL study (3113 children) and performed single SNP association, haplotype association and TNC and NPSR1 gene-gene interaction analyses. Our experimental results show NPS-dependent upregulation of TNC-mRNA. The genotyping results indicate single SNP and haplotype associations for several SNPs in TNC with the most significant association to rhinoconjunctivitis for a haplotype, with a frequency of 29% in cases (P = 0.0005). In asthma and atopic sensitization significant gene-gene interactions were found between TNC and NPSR1 SNPs, indicating that depending on the NPSR1 genotype, TNC can be associated with either an increased or a decreased risk of disease. We conclude that variations in TNC modifies, not only risk for asthma, but also for rhinoconjunctivitis. Furthermore, we show epistasis based on both a direct suggested regulatory effect and a genetic interaction between NPSR1 and TNC. These results suggest merging of previously independent pathways of importance in the development of asthma- and allergy-related trait

Longer Leukocyte Telomere Length Is Associated with Smaller Hippocampal Volume among Non-Demented APOE ε3/ε3 Subjects

Telomere length shortens with cellular division, and leukocyte telomere length is used as a marker for systemic telomere length. The hippocampus hosts adult neurogenesis and is an important structure for episodic memory, and carriers of the apolipoprotein E ε4 allele exhibit higher hippocampal atrophy rates and differing telomere dynamics compared with non-carriers. The authors investigated whether leukocyte telomere length was associated with hippocampal volume in 57 cognitively intact subjects (29 ε3/ε3 carriers; 28 ε4 carriers) aged 49–79 yr. Leukocyte telomere length correlated inversely with left (rs = −0.465; p = 0.011), right (rs = −0.414; p = 0.025), and total hippocampus volume (rs = −0.519; p = 0.004) among APOE ε3/ε3 carriers, but not among ε4 carriers. However, the ε4 carriers fit with the general correlation pattern exhibited by the ε3/ε3 carriers, as ε4 carriers on average had longer telomeres and smaller hippocampi compared with ε3/ε3 carriers. The relationship observed can be interpreted as long telomeres representing a history of relatively low cellular proliferation, reflected in smaller hippocampal volumes. The results support the potential of leukocyte telomere length being used as a biomarker for tapping functional and structural processes of the aging brain

Association of genetic variation with systolic and diastolic blood pressure among African Americans: the Candidate Gene Association Resource study

The prevalence of hypertension in African Americans (AAs) is higher than in other US groups; yet, few have performed genome-wide association studies (GWASs) in AA. Among people of European descent, GWASs have identified genetic variants at 13 loci that are associated with blood pressure. It is unknown if these variants confer susceptibility in people of African ancestry. Here, we examined genome-wide and candidate gene associations with systolic blood pressure (SBP) and diastolic blood pressure (DBP) using the Candidate Gene Association Resource (CARe) consortium consisting of 8591 AAs. Genotypes included genome-wide single-nucleotide polymorphism (SNP) data utilizing the Affymetrix 6.0 array with imputation to 2.5 million HapMap SNPs and candidate gene SNP data utilizing a 50K cardiovascular gene-centric array (ITMAT-Broad-CARe [IBC] array). For Affymetrix data, the strongest signal for DBP was rs10474346 (P= 3.6 × 10−8) located near GPR98 and ARRDC3. For SBP, the strongest signal was rs2258119 in C21orf91 (P= 4.7 × 10−8). The top IBC association for SBP was rs2012318 (P= 6.4 × 10−6) near SLC25A42 and for DBP was rs2523586 (P= 1.3 × 10−6) near HLA-B. None of the top variants replicated in additional AA (n = 11 882) or European-American (n = 69 899) cohorts. We replicated previously reported European-American blood pressure SNPs in our AA samples (SH2B3, P= 0.009; TBX3-TBX5, P= 0.03; and CSK-ULK3, P= 0.0004). These genetic loci represent the best evidence of genetic influences on SBP and DBP in AAs to date. More broadly, this work supports that notion that blood pressure among AAs is a trait with genetic underpinnings but also with significant complexit

Novel genetic loci associated with hippocampal volume

The hippocampal formation is a brain structure integrally involved in episodic memory, spatial navigation, cognition and stress responsiveness. Structural abnormalities in hippocampal volume and shape are found in several common neuropsychiatric disorders. To identify the genetic underpinnings of hippocampal structure here we perform a genome-wide association study (GWAS) of 33,536 individuals and discover six independent loci significantly associated with hippocampal volume, four of them novel. Of the novel loci, three lie within genes (ASTN2, DPP4 and MAST4) and one is found 200 kb upstream of SHH. A hippocampal subfield analysis shows that a locus within the MSRB3 gene shows evidence of a localized effect along the dentate gyrus, subiculum, CA1 and fissure. Further, we show that genetic variants associated with decreased hippocampal volume are also associated with increased risk for Alzheimer's disease (rg =-0.155). Our findings suggest novel biological pathways through which human genetic variation influences hippocampal volume and risk for neuropsychiatric illness

Novel genetic loci underlying human intracranial volume identified through genome-wide association

Intracranial volume reflects the maximally attained brain size during development, and remains stable with loss of tissue in late life. It is highly heritable, but the underlying genes remain largely undetermined. In a genome-wide association study of 32,438 adults, we discovered five novel loci for intracranial volume and confirmed two known signals. Four of the loci are also associated with adult human stature, but these remained associated with intracranial volume after adjusting for height. We found a high genetic correlation with child head circumference (ρgenetic=0.748), which indicated a similar genetic background and allowed for the identification of four additional loci through meta-analysis (Ncombined = 37,345). Variants for intracranial volume were also related to childhood and adult cognitive function, Parkinson’s disease, and enriched near genes involved in growth pathways including PI3K–AKT signaling. These findings identify biological underpinnings of intracranial volume and provide genetic support for theories on brain reserve and brain overgrowth

Genetic variants in novel pathways influence blood pressure and cardiovascular disease risk.

Blood pressure is a heritable trait influenced by several biological pathways and responsive to environmental stimuli. Over one billion people worldwide have hypertension (≥140 mm Hg systolic blood pressure or  ≥90 mm Hg diastolic blood pressure). Even small increments in blood pressure are associated with an increased risk of cardiovascular events. This genome-wide association study of systolic and diastolic blood pressure, which used a multi-stage design in 200,000 individuals of European descent, identified sixteen novel loci: six of these loci contain genes previously known or suspected to regulate blood pressure (GUCY1A3-GUCY1B3, NPR3-C5orf23, ADM, FURIN-FES, GOSR2, GNAS-EDN3); the other ten provide new clues to blood pressure physiology. A genetic risk score based on 29 genome-wide significant variants was associated with hypertension, left ventricular wall thickness, stroke and coronary artery disease, but not kidney disease or kidney function. We also observed associations with blood pressure in East Asian, South Asian and African ancestry individuals. Our findings provide new insights into the genetics and biology of blood pressure, and suggest potential novel therapeutic pathways for cardiovascular disease prevention
