Cost-of-Living Adjustment Clauses in Union Contracts
Our paper seeks to provide an explanation for why the prevalence of COLA provisions and their characteristics vary widely across U.S. industries. We develop models of optimal risk sharing between a firm and union that allows us to investigate the determinants of a number of characteristics of union contracts. These include the presence of wage indexation, the degree of wage indexation if it exists, the magnitude of deferred noncontingent (on the price level) wage increases, the duration of labor contracts and the trade-off between temporary layoffs and wage indexation. Preliminary empirical tests of some of the implications of the model are conducted using industry data on both the prevalence of COLA provisions and layoff rates, and using contract level data on the characteristics of COLA provisions and contract duration. One key finding is that the level of unemployment insurance benefits appears to simultaneously influence the level of layoffs and the extent of COLA coverage.
Trans-Pacific Partnership Agreement minus one and enhanced criminal penalty for online copyright piracy: Malaysia’s options
The burgeoning of online piracy enables copyright materials to be routinely downloaded and exchanged for free, without any deliberate intention to infringe copyright. These acts were done for the purpose of sharing and attract no commercial value, and, hence, may not be considered as culpable criminal conduct because of the lack of intention. The Trans-Pacific Partnership Agreement (TPPA) introduces enhanced criminal provisions which are much harsher than the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) with a view to fight online copyright piracy. Even though the United States of America (US) have withdrawn from the Agreement, the other eleven countries are attempting to revive the Agreement, minus the US. The possibility of the Agreement being eventually implemented by the eleven-member countries is still real. This article examines two new criminal provisions introduced by the TPPA. The first is the criminalization of wilful copyright infringement even if carried out on a non-commercial basis. The second is the culpability of aiding and abetting of copyright offences. As these provisions are already in place in US law, reported judgments from the US on corresponding provisions would be examined. The article concludes with choices that Malaysia could consider in the event these two new obligations are implemented
The principle of situated practice in literacy learning: students’ perspectives
O artigo resulta de uma investigação realizada no âmbito de uma iniciativa governamental destinada a melhorar os níveis de literacia nas séries iniciais do ensino fundamental em Portugal. A investigadora estudou as representações dos alunos sobre essa experiência por meio da realização de entrevistas em grupo. Este artigo analisa os dados referentes às representações dos alunos sobre uma das dimensões pedagógicas centrais da aprendizagem da literacia, nomeadamente a constituída pela prática situada. A análise qualitativa revela representações muito positivas sobre a prática que situou a aprendizagem, tendo os alunos expressado opiniões e sentimentos extremamente favoráveis sobre a prática de aprendizagem de literacia que experimentaram. A análise dos dados desvelou ainda que o contexto que situou a aprendizagem foi ativo, lúdico, colaborativo e mediado pelas TIC. Esses resultados fundamentam, do ponto de vista único dos próprios aprendentes, uma redefinição do entendimento atual do princípio da prática situada da literacia nas séries iniciais do ensino fundamental, no sentido do reconhecimento da centralidade da ludicidade nessa aprendizagem.This article derives from research developed in the context
of the implementation of a governmental initiative aimed to
enhance literacy learning in primary education in Portugal.
The researcher studied students’ representations about
their learning experience through group interviews. This
article focuses on data concerning students’ representations
about one of the central pedagogical dimensions of literacy
learning, namely situated practice. Qualitative analysis
revealed students’ very positive representations about the
practice which situated their learning, as they expressed
extremely favourable opinions and feelings. Data analysis
further unveiled that the context of learning was active,
playful, collaborative, and mediated by ICT. Such results
provide foundations for a theoretical redefinition of current
conceptions of situated practice by evidencing the centrality
of playfulness as learning practice in the education of the first
grades of primary education. This is an original contribution

Trypanosoma vivax Infections: Pushing Ahead with Mouse Models for the Study of Nagana. I. Parasitological, Hematological and Pathological Parameters
African trypanosomiasis is a severe parasitic disease that affects both humans and livestock. Several different species may cause animal trypanosomosis and although Trypanosoma vivax (sub-genus Duttonella) is currently responsible for the vast majority of debilitating cases causing great economic hardship in West Africa and South America, little is known about its biology and interaction with its hosts. Relatively speaking, T. vivax has been more than neglected despite an urgent need to develop efficient control strategies. Some pioneering rodent models were developed to circumvent the difficulties of working with livestock, but disappointedly were for the most part discontinued decades ago. To gain more insight into the biology of T. vivax, its interactions with the host and consequently its pathogenesis, we have developed a number of reproducible murine models using a parasite isolate that is infectious for rodents. Firstly, we analyzed the parasitical characteristics of the infection using inbred and outbred mouse strains to compare the impact of host genetic background on the infection and on survival rates. Hematological studies showed that the infection gave rise to severe anemia, and histopathological investigations in various organs showed multifocal inflammatory infiltrates associated with extramedullary hematopoiesis in the liver, and cerebral edema. The models developed are consistent with field observations and pave the way for subsequent in-depth studies into the pathogenesis of T. vivax - trypanosomosis
Beyond Anxious Predisposition: Do Padecer de Nervios and Ataque de Nervios Add Incremental Validity to Predictions of Current Distress among Mexican Mothers?
Background
Nervios (PNRV) and ataque de nervios (ATQ) are culture-bound syndromes with overlapping symptoms of anxiety, depression, and dissociation, shown to have inconsistent associations to psychiatric disorder. Few studies test the basic assumption that PNRV and ATQ are uniformly linked to distress outcomes across Latina/o immigrant groups. This study examined: (a) the extent to which acculturative stress, Latino/US American acculturation, and anxious predisposition were associated with lifetime history of ATQ and PNRV, and (b) the extent to which ATQ and PNRV add incremental validity in explaining acculturative stress and psychological distress beyond measures of anxious predisposition.
Method
Participants (n = 82) included Mexican mothers who completed surveys on acculturation, trait anxiety, anxiety sensitivity, lifetime ATQ/PNRV, psychological distress, and acculturative stress.
Results
Lifetime PNRV, but not lifetime ATQ, was significantly predictive of psychological distress. PNRV was also linked to trait anxiety. Psychometric measures of anxious predisposition (trait anxiety and anxiety sensitivity) were more robust predictors of distress outcomes than lifetime history of ATQ/PNRV.
Conclusion
Inquiry into lifetime history of nervios may be a useful point of entry in talking to Mexican immigrant mothers about stress and distress. However, standard tools for assessing anxiety sensitivity and trait anxiety appear most useful in identifying and explaining the presence of psychological distress. Further research is needed to determine the cross-cultural relevance of trait anxiety and anxiety sensitivity, and its implications for the development of anxiety treatments that are effective across cultures
Building a conceptual framework for determining individual differences of accessibility to tourist attractions
This paper introduces a conceptual framework for determining individual differences of accessibility to tourist attractions. The framework includes three components: factors affecting accessibility to tourist attractions; the individual characteristics of tourists, such as age, gender; and other explanatory variables that assist in explaining why accessibility to tourist attractions varies. This research indicates that measures of accessibility should include not only commonly used factors such as socio-demographic variables and distance, but also the facilities available at various attractions, management and operational aspects relating to the attraction (what we term "functions"), and the infrastructure used to move between specific attractions (what we term "connectivity of networks"). A case study of the Ningaloo Coast region was conducted to identify individual difference in evaluation of accessibility to tourist attractions. We show that the evaluation of accessibility varies among tourist groups due to their spatial abilities, individual values and needs, and preparatory set
The 5p15.33 Locus Is Associated with Risk of Lung Adenocarcinoma in Never-Smoking Females in Asia
Genome-wide association studies of lung cancer reported in populations of European background have identified three regions on chromosomes 5p15.33, 6p21.33, and 15q25 that have achieved genome-wide significance with p-values of 10−7 or lower. These studies have been performed primarily in cigarette smokers, raising the possibility that the observed associations could be related to tobacco use, lung carcinogenesis, or both. Since most women in Asia do not smoke, we conducted a genome-wide association study of lung adenocarcinoma in never-smoking females (584 cases, 585 controls) among Han Chinese in Taiwan and found that the most significant association was for rs2736100 on chromosome 5p15.33 (p = 1.30×10−11). This finding was independently replicated in seven studies from East Asia totaling 1,164 lung adenocarcinomas and 1,736 controls (p = 5.38×10−11). A pooled analysis achieved genome-wide significance for rs2736100. This SNP marker localizes to the CLPTM1L-TERT locus on chromosome 5p15.33 (p = 2.60×10−20, allelic risk = 1.54, 95% Confidence Interval (CI) 1.41–1.68). Risks for heterozygote and homozygote carriers of the minor allele were 1.62 (95% CI; 1.40–1.87), and 2.35 (95% CI: 1.95–2.83), respectively. In summary, our results show that genetic variation in the CLPTM1L-TERT locus of chromosome 5p15.33 is directly associated with the risk of lung cancer, most notably adenocarcinoma
Automated telephone communication systems for preventive healthcare and management of long-term conditions
Background
Automated telephone communication systems (ATCS) can deliver voice messages and collect health-related information from patients
using either their telephone’s touch-tone keypad or voice recognition software. ATCS can supplement or replace telephone contact
between health professionals and patients. There are four different types of ATCS: unidirectional (one-way, non-interactive voice
communication), interactive voice response (IVR) systems, ATCS with additional functions such as access to an expert to request advice
(ATCS Plus) and multimodal ATCS, where the calls are delivered as part of a multicomponent intervention.
Objectives
To assess the effects of ATCS for preventing disease and managing long-term conditions on behavioural change, clinical, process,
cognitive, patient-centred and adverse outcomes.
Search methods
We searched 10 electronic databases (the Cochrane Central Register of Controlled Trials; MEDLINE; Embase; PsycINFO; CINAHL;
Global Health; WHOLIS; LILACS; Web of Science; and ASSIA); three grey literature sources (Dissertation Abstracts, Index to Theses,
Australasian Digital Theses); and two trial registries (www.controlled-trials.com; www.clinicaltrials.gov) for papers published between
1980 and June 2015.
Selection criteria
Randomised, cluster- and quasi-randomised trials, interrupted time series and controlled before-and-after studies comparing ATCS
interventions, with any control or another ATCS type were eligible for inclusion. Studies in all settings, for all consumers/carers, in any
preventive healthcare or long term condition management role were eligible.
Data collection and analysis
We used standard Cochrane methods to select and extract data and to appraise eligible studies.
Main results
We included 132 trials (N = 4,669,689). Studies spanned across several clinical areas, assessing many comparisons based on evaluation
of different ATCS types and variable comparison groups. Forty-one studies evaluated ATCS for delivering preventive healthcare, 84 for
managing long-term conditions, and seven studies for appointment reminders. We downgraded our certainty in the evidence primarily
because of the risk of bias for many outcomes. We judged the risk of bias arising from allocation processes to be low for just over half
the studies and unclear for the remainder. We considered most studies to be at unclear risk of performance or detection bias due to
blinding, while only 16% of studies were at low risk. We generally judged the risk of bias due to missing data and selective outcome
reporting to be unclear.
For preventive healthcare, ATCS (ATCS Plus, IVR, unidirectional) probably increase immunisation uptake in children (risk ratio (RR)
1.25, 95% confidence interval (CI) 1.18 to 1.32; 5 studies, N = 10,454; moderate certainty) and to a lesser extent in adolescents (RR
1.06, 95% CI 1.02 to 1.11; 2 studies, N = 5725; moderate certainty). The effects of ATCS in adults are unclear (RR 2.18, 95% CI
0.53 to 9.02; 2 studies, N = 1743; very low certainty).
For screening, multimodal ATCS increase uptake of screening for breast cancer (RR 2.17, 95% CI 1.55 to 3.04; 2 studies, N = 462;
high certainty) and colorectal cancer (CRC) (RR 2.19, 95% CI 1.88 to 2.55; 3 studies, N = 1013; high certainty) versus usual care.
It may also increase osteoporosis screening. ATCS Plus interventions probably slightly increase cervical cancer screening (moderate
certainty), but effects on osteoporosis screening are uncertain. IVR systems probably increase CRC screening at 6 months (RR 1.36,
95% CI 1.25 to 1.48; 2 studies, N = 16,915; moderate certainty) but not at 9 to 12 months, with probably little or no effect of IVR
(RR 1.05, 95% CI 0.99, 1.11; 2 studies, 2599 participants; moderate certainty) or unidirectional ATCS on breast cancer screening.
Appointment reminders delivered through IVR or unidirectional ATCS may improve attendance rates compared with no calls (low
certainty). For long-term management, medication or laboratory test adherence provided the most general evidence across conditions
(25 studies, data not combined). Multimodal ATCS versus usual care showed conflicting effects (positive and uncertain) on medication
adherence. ATCS Plus probably slightly (versus control; moderate certainty) or probably (versus usual care; moderate certainty) improves
medication adherence but may have little effect on adherence to tests (versus control). IVR probably slightly improves medication
adherence versus control (moderate certainty). Compared with usual care, IVR probably improves test adherence and slightly increases
medication adherence up to six months but has little or no effect at longer time points (moderate certainty). Unidirectional ATCS,
compared with control, may have little effect or slightly improve medication adherence (low certainty). The evidence suggested little or
no consistent effect of any ATCS type on clinical outcomes (blood pressure control, blood lipids, asthma control, therapeutic coverage)
related to adherence, but only a small number of studies contributed clinical outcome data.
The above results focus on areas with the most general findings across conditions. In condition-specific areas, the effects of ATCS
varied, including by the type of ATCS intervention in use.
Multimodal ATCS probably decrease both cancer pain and chronic pain as well as depression (moderate certainty), but other ATCS
types were less effective. Depending on the type of intervention, ATCS may have small effects on outcomes for physical activity,
weight management, alcohol consumption, and diabetes mellitus. ATCS have little or no effect on outcomes related to heart failure,
hypertension, mental health or smoking cessation, and there is insufficient evidence to determine their effects for preventing alcohol/
substance misuse or managing illicit drug addiction, asthma, chronic obstructive pulmonary disease, HIV/AIDS, hypercholesterolaemia,
obstructive sleep apnoea, spinal cord dysfunction or psychological stress in carers.
Only four trials (3%) reported adverse events, and it was unclear whether these were related to the intervention
