title: Patient characteristics and comorbidities influence walking distance in symptomatic peripheral arterial disease: a one-year physiotherapy cohort study

description: Objectives The aim of this study is to investigate the association between age, gender, body-mass index, smoking behavior, orthopedic comorbidity, neurologic comorbidity, cardiac comorbidity, vascular comorbidity, pulmonic comorbidity, internal comorbidity and Initial Claudication Distance during and after Supervised Exercise Therapy at 1, 3, 6 and 12 months in a large sample of patients with Intermittent Claudication. Methods Data was prospectively collected in standard physiotherapy care. Patients received Supervised Exercise Therapy according to the guideline Intermittent Claudication of the Royal Dutch Society for Physiotherapy. Three-level mixed linear regression analysis was carried out to analyze the association between patient characteristics, comorbidities and Initial Claudication Distance at 1, 3, 6 and 12 months. Results Data from 2995 patients was analyzed. Results showed that being female, advanced age and a high body-mass index were associated with lower Initial Claudication Distance at all-time points (p= 0.000). Besides, a negative association between cardiac comorbidity and Initial Claudication Distance was revealed (p= 0.011). The interaction time by age, time by body-mass index and time by vascular comorbidity were significantly associated with Initial Claudication Distance (p≤ 0.05). Per year increase in age (range: 33-93 years), the reduction in Initial Claudication Distance was 8m after 12 months of Supervised Exercise Therapy. One unit increase in body-mass index (range: 16-44 kg/m2) led to 10m less improvement in Initial Claudication Distance after 12 months and for vascular comorbidity the reduction in improvement was 85m after 12 months. Conclusions This study reveals that females, patients at advanced age, patients with a high body-mass index and cardiac comorbidity are more likely to show less improvement in Initial Claudication Distances (ICD) after 1, 3, 6 and 12 months of Supervised Exercise Therapy. Further research should elu
cidate treatment adaptations that optimize treatment outcomes for these subgroups.

title: The impact of gender and business training for female microfinance clients in Vietnam

description: This study deals with the impact of offering a gender and business training to female microfinance clients in Vietnam using a randomization control trial (RCT). A specific feature of the study is that a random group of female borrowers were allowed to take their husbands to the trainings. The study explicitly tests whether the impact of the training is conditional on the presence of husbands. The study also differentiates between short term effects and longer term effects of the training. We consider impacts on a range of outcomes, varying from knowledge to profits, and “unpack” profits by distinguishing between the returns to different activities. We also consider the impact on different dimensions of female empowerment. Our results provide support for the finance-plus approach to development. We find that the gender and business trainings improve knowledge, increase the uptake of new business practices, and after some delay cause an increase in profits. We also find that
the magnitude of the measured impact varies over time, and that measuring the impact on downstream variables like profits is likely to result in under-estimates of the true impact if data are collected too early after the end of the training. We also document effects at the extensive margin, and find that participating in the training may increase the start-up of new economic activities and slow-down the exit of existing ones. In addition, we provide evidence that female borrowers who receive access to training experience more internal control beliefs, less relational friction, and more intra-household decision making power. Finally, we document that the general business training significantly increased the returns to agricultural practices, even if agriculture was not specifically targeted – an example of a household-level spillover across economic sectors. Not all our hypotheses were supported by the data. Most importantly, we do not document statistically robust effects of including husbands in the training for most of our outcome variables. However, we are careful not to dismiss the potential contribution of participating husbands too lightly. First, while the differences across treatment arms are not statistically significant, we consistently find that estimated treatment effects on profits are larger when men are involved in the trainings. Second, their participation was appreciated by the women, and it is possible that positive outcomes emerges along other dimensions (i.e. beyond business-related variables). We show that the attendance of man can have a (small) positive effect, but we don’t have enough information about the impacts of “own husbands”. Future research needs to examine this with a larger sample, or using more salient incentives, so that a larger share of the target population of men participates in the trainings.

title: Rapportage archeologisch pendelonderzoek Nederweert-Wessemerdijk (1987)

description: &lt;p&gt;Door de Weerter paragnost Mathieu Linders (1911-1996) werd in 1987 door middel van pendelbewegingen op een kaart gepoogd de locatie en omvang van prehistorische en romeinse grafvelden vast te stellen. In een tweetal sessies werden zijn bevindingen gedocumenteerd en beproefd. Het overgrote deel van zijn bevindingen is tot de dag van vandaag niet verifieerbaar wegens onvoldende archeologisch onderzoek op de relevante locaties. Op de plekken waar wél verificatie mogelijk was, leidde dat op een plek (Wessemerdijk) tot scepsis (vanwege veronderstelde voorkennis bij de paragnost) en op een andere plek (Bredeweg 32) tot verrassende goede resultaten. &lt;br&gt; &lt;br&gt;De conclusie moet voorlopig zijn dat de exercities onwetenschappelijk zijn en statistisch niet overtuigende resultaten hebben opgeleverd. Wat overigens geen afbreuk doet aan het belang om deze waarnemingen te documenteren en te verifiëren in de verdere toekomst.&lt;/p&gt;

title: Plangebied Vogelenzang en Bennebroek te Bloemendaal, gemeente Bloemendaal; archeologisch vooronderzoek: een bureauonderzoek

description: &lt;p&gt;In opdracht van NKM heeft RAAP in februari 2021 een archeologisch vooronderzoek in de vorm van een bureauonderzoek uitgevoerd voor het plangebied Vogelenzang en Bennebroek te Bloemendaal in de gemeente Bloemendaal. In het plan gebied is het verwijderen van bestaande kabels en het leggen van nieuwe gepland. Het onderzoek vond plaats in het kader van een omgevingsvergunning. Op grond van de onderzoeksresultaten en onder verwijzing naar de doelstellingen, kunnen de volgende uitspraken worden gedaan: In het gehele plangebied is sprake van een hoge verwachting op resten van menselijke bewoning vanaf het Neolithicum, behalve in het oostelijke deel waar een veengebied ligt. De beoogde ingrepen zijn 20 cm breed en 40 of 60 cm diep. Behalve in drie zones met een dubbelbestemming ‘Waarde Archeologie 2’ (het centrum van Vogelenzang en Bennebroek en een archeologisch terrein aan de Bekslaan) betekent dit dat archeologisch onderzoek in het plangebied niet verplicht is in het kader van het verstrekken van een omgevingsvergunning voor deze ingrepen. In één van deze zones (het terrein met resten van een nederzetting uit de Bronstijd aan de Bekslaan) zijn geen ingrepen gepland. De andere twee zones betreffen de historische kern van Vogelenzang en Bennebroek. In deze twee zones worden ook resten van stedelijke bebouwing en wegverhardingen verwacht uit in ieder geval de periode vanaf de 17e eeuw en mogelijk zelfs eerder. Deze stedelijke bebouwing zal oudere archeologische resten (deels) verstoord hebben. De geplande ingrepen bieden slechts zeer beperkte mogelijkheden tot het doen van archeologische waarnemingen en het waarderen van aangetroffen resten. Wel is het goed mogelijk om te beoordelen of de ingrepen worden uitgevoerd in reeds verstoorde grond. Ook het lokaliseren, eventueel dateren en documenteren van aangetroffen resten is mogelijk.&lt;/p&gt;&lt;p&gt;Op basis van het bovenstaande wordt geadviseerd de ingrepen in de twee zones met een dubbelbestemming ‘Waarde Archeologie 2’ waar ingrepen gepland zijn, namelijk in de historische kern van Vogelenzang en Bennebroek de ontgraving archeologisch te laten begeleiden. De omvang van de ingrepen en de verwachte archeologische resten maken booronderzoek ongeschikt als prospectiemethode. De verwachte resten uit de 17e eeuw en daarna zullen puin bevatten, waarop een boor zal stuiten. Een op puin stuitende boring is echter precies dat: een gestuite boring die op los puin in verstoorde grond is gestuit, of op oude muur- of funderingsresten. Het verschil kan niet worden bepaald zonder graafwerk. Vooronderzoek door middel van graafwerk vereist dat de bodem ten minste tweemaal open moet: eenmaal voor het vooronderzoek en eenmaal voor het leggen van de kabels. Het is beter om die twee activiteiten dan in één keer uit te voeren en dan spreken we van begeleiding, of in KNA-jargon: proefsleuvenonderzoek, variant archeologische begeleiding, met eventueel doorstart naar een opgraving (variant archeologische begeleiding).&lt;/p&gt;

title: Price anomalies in the used car market [Dataset]

description: Using two different samples – one based on newspaper advertisements, the other Internet-based – we identify some price anomalies in the used car market in the Netherlands. First, prices of used cars depend on their age in calendar years rather than months. Second, there is some evidence that crossing 100,000 km induces a sudden additional price reduction. Third, a new license plate format, something with no intrinsic value whatsoever, increases a car’s price by about 4%. We discuss possible explanations for these results.
