The north coast of Peru is among the most extensively surveyed regions in the world, yet variation in research questions, sampling strategies and chronological and geospatial controls among survey projects makes comparison of disparate datasets difficult. To contextualise these issues, the authors present a systematic survey of satellite imagery focusing on hilltop fortifications in the Jequetepeque and Santa Valleys. This digital recontextualisation of pedestrian survey data demonstrates the potential of hybrid methodologies to substantially expand both the identification of archaeological sites within difficult terrain and, consequently, our understanding of the function of defensive sites.

Objective:
To examine the labelling status of trans-fat of pre-packaged foods sold in Hong Kong.
Design:Data from 19 027 items in the 2019 FoodSwitch Hong Kong database were used. Ingredient lists were screened to identify specific (e.g. partially hydrogenated vegetable oil, PHVO) and non-specific trans-fat ingredient indicators (e.g. hydrogenated oil). Trans-fat content was obtained from the on-pack nutrition labels, which was converted into proportion of total fat (%total fat). Descriptive statistics were calculated for trans-fat content and the number of specific, non-specific and total trans-fat ingredients indicators found on the ingredients lists. Comparisons were made between regions using one-way ANOVA and χ2 for continuous and categorical variables, respectively.
Setting:Cross-sectional audit.
Participants:Not applicable.
Results:A total of 729 items (3·8 % of all products) reported to contain industrially produced trans-fat, with a median of 0·4 g/100 g or 100 ml (interquartile range (IQR): 0·1–0·6) and 1·2 %totalfat (IQR: 0·6–2·9). ‘Bread and bakery products’ had the highest proportion of items with industrially produced trans-fat (18·9 %). ‘Non-alcoholic beverages’ had the highest proportion of products of ‘false negatives’ labelling (e.g. labelled as 0 trans-fat but contains PHVO; 59·3 %). The majority of products with trans-fat indicator originated from Asia (70 %).
Conclusions:According to the labelling ∼4 % of pre-packaged food and beverages sold in Hong Kong in 2019 contained industrially produced trans-fat, and a third of these had trans-fat >2 %total fat. The ambiguous trans-fat labelling in Hong Kong may not effectively assist consumers in identifying products free from industrially produced trans-fat.

Objective
To determine the efficacy of 2 types of antimicrobial privacy curtains in clinical settings and the costs involved in replacing standard curtains with antimicrobial curtains.
DesignA prospective, open-labeled, multicenter study with a follow-up duration of 6 months.
SettingThis study included 12 rooms of patients with multidrug-resistant organisms (MDROs) (668 patient bed days) and 10 cubicles (8,839 patient bed days) in the medical, surgical, neurosurgical, orthopedics, and rehabilitation units of 10 hospitals.
MethodCulture samples were collected from curtain surfaces twice a week for 2 weeks, followed by weekly intervals.
ResultsWith a median hanging time of 173 days, antimicrobial curtain B (quaternary ammonium chlorides [QAC] plus polyorganosiloxane) was highly effective in reducing the bioburden (colony-forming units/100 cm2, 1 vs 57; P < .001) compared with the standard curtain. The percentages of MDRO contamination were also significantly lower on antimicrobial curtain B than the standard curtain: methicillin-resistant Staphylococcus aureus, 0.5% vs 24% (P < .001); carbapenem-resistant Acinetobacter spp, 0.2% vs 22.1% (P < .001); multidrug-resistant Acinetobacter spp, 0% vs 13.2% (P < .001). Notably, the median time to first contamination by MDROs was 27.6 times longer for antimicrobial curtain B than for the standard curtain (138 days vs 5 days; P = .001).
ConclusionsAntimicrobial curtain B (QAC plus polyorganosiloxane) but not antimicrobial curtain A (built-in silver) effectively reduced the microbial burden and MDRO contamination compared with the standard curtain, even after extended use in an active clinical setting. The antimicrobial curtain provided an opportunity to avert indirect costs related to curtain changing and laundering in addition to improving patient safety.

Background:
Driving in persons with dementia poses risks that must be counterbalanced with the importance of the care for autonomy and mobility. Physicians often find substantial challenges in the assessment and reporting of driving safety for persons with dementia. This paper describes a driving in dementia decision tool (DD-DT) developed to aid physicians in deciding when to report older drivers with either mild dementia or mild cognitive impairment to local transportation administrators.
Methods:A multi-faceted, computerized decision support tool was developed, using a systematic literature and guideline review, expert opinion from an earlier Delphi study, as well as qualitative interviews and focus groups with physicians, caregivers of former drivers with dementia, and transportation administrators. The tool integrates inputs from the physician-user about the patient's clinical and driving history as well as cognitive findings, and it produces a recommendation for reporting to transportation administrators. This recommendation is translated into a customized reporting form for the transportation authority, if applicable, and additional resources are provided for the patient and caregiver.
Conclusions:An innovative approach was needed to develop the DD-DT. The literature and guideline review confirmed the algorithm derived from the earlier Delphi study, and barriers identified in the qualitative research were incorporated into the design of the tool.

Studies have shown that management training and development (MTD) can be a strategic weapon in improving performance and in building and sustaining competitive advantage. However, recent studies suggest that MTD is under-valued and under-used as a strategic tool by New Zealand firms as, despite a managerial skill shortage, New Zealand firms have not invested heavily in MTD. The present paper discusses a study of employer-based MTD in New Zealand that investigated managerial attitudes towards, and propensity to engage in, MTD. The study found several indicators that predict four MTD related variables (the MTD index, the percent of payroll spent on MTD, the increase in training expenditure and expected future increases in the MTD budget). The results suggest organisations that engage in MTD improve organisational effectiveness and implement their business strategy better and that MTD was seen as an important tool in gaining a competitive advantage.

Summary
Introduction
The aim of the chapter is to show how actor–network theorizing can contribute to our understanding of strategy as practice. Practice theorization offers a broad church, with many partially overlapping sets of interests and concerns, as discussed in the collection of writings found in The Practice Turn in Contemporary Theory (Schatzki, Knorr Cetina and von Savigny 2001). In this chapter we seek to show the variety of points of contact between the sensitivities making up a strategy-as-practice research agenda and those arising from actor–network theory as one particular part of this broader set of theories. Through such an engagement, we find opportunities for SAP research to pursue its agenda and to address a range of critiques that it has faced from those frustrated that its progress so far has not been as great as hoped.
In setting itself a core agenda, the strategy-as-practice approach questions the view that ‘strategy is something organizations have’, with a view to shifting to consideration of ‘strategy as something people do in organizations’ (Whittington 2006). Pursuing such an agenda has radical implications, questioning as it does the notion of strategy as a legitimate resource at the hands of top management. By making practice central to understanding strategy, this literature suggests that the locus of strategizing is dispersed (for anyone participating in the organization has the potential to engage in strategizing) and the instantiation of strategy may follow a complex, non-linear and less determinate trajectory involving the interplay of multiple conflicting logics.
Among all of the development and debate around the strategy-as-practice agenda, we trace some particular criticisms that have been made (namely Araujo and Easton 1996; Whittington 2006; Rasche and Chia 2009). We focus our discussion around these, since we find that they are helpful as a way to reiterate and develop central aspects of the agenda of SAP research. More importantly, given the focus of this chapter, we find that these criticisms can be directly addressed through the adoption of elements of actor–network theorizing into strategy-as-practice research. Overall, then, we present these criticisms not as judgement of the quality or intentions of the field. Rather, we see them as comments made about particular subsets of studies that serve a useful purpose as conceptual tools to further strengthen and develop the field. With this caveat on the role of these criticisms in this chapter firmly in mind, we now briefly rehearse them.

Background
Reaction time (RT) variability is one of the strongest findings to emerge in cognitive-experimental research of attention deficit hyperactivity disorder (ADHD). We set out to confirm the association between ADHD and slow and variable RTs and investigate the degree to which RT performance improves under fast event rate and incentives. Using a group familial correlation approach, we tested the hypothesis that there are shared familial effects on RT performance and ADHD.
MethodA total of 144 ADHD combined-type probands, 125 siblings of the ADHD probands and 60 control participants, ages 6–18, performed a four-choice RT task with baseline and fast-incentive conditions.
ResultsADHD was associated with slow and variable RTs, and with greater improvement in speed and RT variability from baseline to fast-incentive condition. RT performance showed shared familial influences with ADHD. Under the assumption that the familial effects represent genetic influences, the proportion of the phenotypic correlation due to shared familial influences was estimated as 60–70%.
ConclusionsThe data are inconsistent with models that consider RT variability as reflecting a stable cognitive deficit in ADHD, but instead emphasize the extent to which energetic or motivational factors can have a greater effect on RT performance in ADHD. The findings support the role of RT variability as an endophenotype mediating the link between genes and ADHD.

Fixed exchange rates implemented to increase credibility and attract foreign investment, or as an alternative approach to stabilization in high inflation economies, have been shown to be successful in expanding economic activity and correcting inflation in the short term but often lead to undesirable outcomes in the medium to long term. Although there is a wealth of literature documenting the boom-bust cycles associated with the adoption of a nominal anchor, no adequate explanation has been proffered as to governments repeatedly choosing policies that are self-defeating. The authors address this question with a political economy explanation based on the notion of a self-interested government for which short-term stabilization is attractive in the face of incentives posed by the electoral cycle. If the election coincides with the boom phase of an exchange rate—based stabilization, incumbent governments increase the likelihood of gaining reelection, and the bust phase will develop, if at all, only after the contest. The authors thus suggest a modified version of the traditional political business cycle. From the standpoint of a self-interested office-seeking government, exchange rate—based stabilizations can make good political sense. Empirical results based on an analysis of eighteen Latin American countries from 1970 to 1999 support the insights of the argument: movements towards a more fixed exchange rate are greater than three times more likely in a preelection period than in other stages of the electoral cycle.

The viscous properties of the multi component Zr41.2 Ti13.8 Cu12.5 Ni10.0 Be22.5 bulk metallic glass forming alloy was studied above the liquidus temperature. A shear thinning behavior for the molten alloy has been discovered. The shear thinning behavior can be characterized as a power law fluid with a power-law index of -0.5. Additionally, at low shear rates and temperatures near the liquidus temperature a visco-elastic type response in the flow behavior is observed.

Through a pooled cross-section time-series analysis of the determinants of wage inequality in sixteen OECD countries from 1973 to 1995, we explore how political-institutional variables affect the upper and lower halves of the wage distribution. Our regression results indicate that unionization, centralization of wage bargaining and public-sector employment primarily affect the distribution of wages by boosting the relative position of unskilled workers, while the egalitarian effects of Left government operate at the upper end of the wage hierarchy, holding back the wage growth of well-paid workers. Further analysis shows that the differential effects of government partisanship are contingent on wage-bargaining centralization: in decentralized bargaining systems, Left government is associated with compression of both halves of the wage distribution.

Summary
A central tenet of the corporatism literature is that the Phillips curve trade-off between inflation and unemployment is mitigated in countries with powerful and centrally coordinated organized labor movements. Most empirical studies, however, are based on data about labor market institutions from the early 1970s and refer to macroeconomic outcomes in the decade following the first OPEC oil shock in 1973. Recent case studies, in contrast, suggest that corporatism broke down during the 1980s in its Scandinavian bastions, in a cycle of strikes, inflation, and ultimately higher unemployment (Iversen 1996; Pontusson and Swenson 1996). We argue that one important reason for the apparent economic problems of strong labor regimes in recent years has been the growth of publicsector unions. So long as public-sector unions are not “too strong” (this limit is estimated empirically), corporatist institutions continue to promote both price stability and low rates of unemployment.
Encompassing labor movements - those that cover large sections of the work force in a relatively small number of independent unions and in which authority is concentrated in the hands of leaders of a single trade union confederation — provide an organizational structure that is conducive to low inflation and low unemployment because they mitigate distributional conflict among all workers. There is a limit, however, to the ability of encompassing labor movements to perform this role. Where public-sector unions are extremely strong (as has recently been the case in Scandinavia), confederation leaders cannot stop public-sector workers from using their organizational power to bid up their wages to levels that have deleterious consequences for the private sector - and especially for those industries that are exposed to international trade.
This chapter relies on three recent systematic studies of labor movements in Organization for Economic Development and Cooperation (OECD) countries that allow us to test the labor market institutions-performance nexus more precisely than has hitherto been the case. We use Visser's (1991) data on publicsector unions, Golden and Wallerstein's (1995) analysis of the structural attributes of organized labor movements, and Traxler's (1994) study of the coverage of collectively bargained wage contracts. These data sources allow us to construct time-sensitive measures of theoretically important attributes of organized labor movements.
