The impact of “procurement with impact”: measuring the short-term effects of sustainable public procurement policy on the environmental friendliness of tenders
Authors: van Berkel Jacco Robbert Jan , Schotanus Fredo 
Published: November 2021

Purpose
This paper aims to study the short-term effects of a new procurement policy document on the inclusion of environmental requirements and green award criteria in tenders. The policy document is named “Procurement with Impact” and was released by the Dutch central government to further stimulate Sustainable Public Procurement (SPP).

Design/methodology/approach
Central government tenders were quantitatively analyzed in the six months prior and after the release of the new policy on their inclusion of environmental concerns. This judgment was made based on the role of environmental concerns in the requirements and the award criteria. As a control group, the same was done on a municipal level, for which the new policy document does not apply. Each of the four samples contained 60 tenders. Data was acquired via the European public procurement database TED. In the analysis, a chi-square test was used to measure whether a significant difference exists between the two periods for each group.

Findings
Results show that central government has procured in a more environmentally concerned way after the release of “Procurement with Impact.” Within a year, the number of green tenders conducted by central government significantly increased from 30% to 55%. No significant difference was found on a municipal level.

Social implications
SPP has received increasing attention over the past few decades but has not led to implementation of its principles in most public tenders. As SPP can have a major impact on a more sustainable and social society, it is important to understand how policy can influence the sustainability of tenders. The findings of our study show that “Procurement with impact” had a significant positive short-term effect on the inclusion of green award criteria and requirements in public tenders. Implementing similar SPP policies in other government sectors and other countries could have a substantial effect on the worldwide uptake of SPP.

Originality/value
“Procurement with Impact” contains a clear sustainable vision embracing the principles of SPP. This government policy takes into account several SPP barriers and drivers and satisfies several policy theory conditions. The authors show in the paper that this policy is an effective instrument for increasing the inclusion of environmental concerns in tenders. As the difference is already significant within a year, this could also reflect the readiness of tenderers to turn to SPP once there is a clear organization wide policy.

Purpose
To treat water pollution, especially the contamination resulted from organic dyes has aroused significant attention around the world, this study aims to prepare the metal organic framework (MOF) materials hybridizing with poly(p-phenylene terephthalamide) (PPTA) by means of a facile refluxing method and to systematically investigate adsorption performance for anionic dye Congo red as target molecule from aqueous solution.

Design/methodology/approach
The MOF materials hybridized by PPTA were fabricated by virtue of a facile refluxing method, characterized by thermogravimetric analysis, X-ray powder diffraction, Fourier transform infrared and pore structure.

Findings
The results showed that pseudo-second-order kinetic model could better describe the adsorption process for all the four materials, whereas Elovich model also fitted the process for the hybrid materials with PPTA. Adsorption isotherm analyses indicated that Langmuir isotherm could be used to describe the adsorption process. Introduction of appropriate amount of PPTA could enhance the adsorption affinity of the MOF materials for Congo red, and the maximum adsorption capacity could reach as high as 1,053.41 mg/g while that of the MOF material without PPTA was 666.67 mg/g, indicating introduction of PPTA could change the microenvironment of the MOF materials and increase the adsorption sites, leading to high adsorption efficiency.

Research limitations/implications
The microstructure of MOF hybridized materials in detail is the further and future investigation.

Practical implications
This study will provide a method to prepare MOF materials with high efficiency to treat anionic dyes like Congo red from aqueous solution.

Originality/value
Owing to the special characteristics of PPTA and similar to carbon tube, PPTA was introduced into MOF material to increased corresponding water stability. Because of aromatic ring and amide group on the surface of PPTA, the adsorption efficiency of the hybridized MOF material with appropriate amount of PPTA was greatly enhanced.
Records management and performance of procurement management units in Tanzania: a case study
Authors: Matto Mordecai Chrysostom 
Published: November 2021

Purpose
This paper aims to examine the influence of records management on the performance of procurement management units (PMUs) in Tanzania.

Design/methodology/approach
To meet the objective of the study, cross-sectional survey design and quantitative approaches were used for data collection and analysis. Preliminary analysis of the data was carried out using descriptive statistics and structural equation modelling was then used to analyse the influence of records management standards on procurement performance. The data were collected from 164 government PMUs in Tanzania.

Findings
The findings revealed that records management attributes significantly affect procurement performance in Tanzania. Furthermore, government policy and integrity factors confound the association between records management and procurement performance.

Practical implications
The policymakers and practitioners of public procurement are required to be aware of records management principles and how each related factor influences the performance of PMUs. They should emphasise proper storage and housing, equipment, arrangement and access and implement electronic records management.

Originality/value
This study shows how the ISO 15489 model can be applied to public procurement processes. This study also provides the lesson that procurement records need to be protected to ensure their authenticity, reliability, integrity and useability.

Published: November 2021

AbstractHow to satisfactorily implement the public–private partnership (PPP) network is the most important target for infrastructure and public services policymakers. In this article, we elaborate on how project‐ and process‐management styles can combine to deliver a satisfactory PPP. This paper uses a fuzzy‐set qualitative comparative analysis to investigate the relationship between management styles and PPP network outcomes. Specifically, we examine the management tools (i.e. results orientation, control, communication and flexibility) and their joint effects on PPP network outcome. Results show that three combinations of sufficient conditions yield satisfactory PPP network outcomes consisting of project‐ and process‐management styles.
Digitally captured signatures: A method for the normalization of force through calibration and the use of the zeta function
Authors: Kalantzis Nikolaos , Platt Andrew W.G. 
Published: November 2021

AbstractDigitally captured signatures (DCS) are entering the scope of the Forensic Handwriting Examiner (FHE), and the meaningful comprehension and comparison of the captured information is essential in order to proceed to the examination of authenticity of DCS. In DCS solutions, force is captured and presented as pressure levels, but the relation between exercised force and the assigned pressure levels is not provided by the manufacturers of these solutions. For this purpose, we constructed an experimental array that allows the correlation of exercised force and assigned pressure levels, in a combination of three different digitizers, six different styli and four different capturing software. This process let us calculate the correlation function that assigns pressure levels to force for each solution (called the Zeta Function). Through this process, it was observed that different solutions follow different Zeta functions. To address this problem, a methodology for normalization of captured data between different solutions was created and demonstrated, using the calculated Zeta function and its inverse.
Identification of two ABCC transporters involved in malathion detoxification in the red flour beetle, Tribolium castaneum
Authors: Rösner Janin , Merzendorfer Hans 
Published: November 2021

AbstractABC transporters have been suggested to be involved in insecticide detoxification in different insect species mainly based on the indirect observation of transcriptional upregulation of ABC gene expression in response to insecticide exposure. Previous studies performed by us and others in the red flour beetle, Tribolium castaneum, have analyzed the function of TcABCA‐C and TcABCG‐H genes using RNA interference (RNAi) and demonstrated that specific TcABCA and TcABCC genes are involved in the elimination of the pyrethroid tefluthrin and the benzoylurea diflubenzuron, because gene silencing increased the beetle's susceptibility to the insecticides. In this study, we focused on the potential functions of TcABCA‐C genes in detoxification of the pyrethroid cyfluthrin (CF), the organophosphate malathion (MAL) and the diacylhdyazine tebufenozide (TBF). Analysis of transcript levels of selected TcABCA‐C genes in response to treatment with these three chemically unrelated insecticides revealed that some genes were particularly upregulated after insecticide treatment. In addition, the ABC inhibitor verapamil synergized significantly the toxicity of MAL but only negligibly CF and TBF toxicities. Finally, silencing of two TcABCC genes by RNAi revealed a significant increase in susceptibility to MAL. In contrast, we did not observe a significant increase in insecticide‐induced mortalities when knocking down TcABC genes in larvae treated with CF or TBF, although they were upregulated in response to insecticide treatment. Our results suggest that two pleiotropic ABCC transporters expressed in metabolic and excretory tissues contribute to the elimination of MAL.

AbstractThe present study was designed to evaluate the insecticidal activity of different concentrations of Foeniculum vulgare and two of its components, trans‐anethole and fenchone, against the different stages of Musca domestica. The tested concentrations were applied through a residual film method and topical application on larvae and pupae respectively. Trans‐anethole achieved the best results against larvae when compared with those of the fennel or fenchone with LC50 values of 0.58%, 1.57%, and 17.22%, respectively. Moreover, tans‐anethole killed 100% of larvae at concentration of 2.5% and fennel achieved the same effect at concentration of 10%, meanwhile fenchone did not reach such an effect at any of the tested concentrations. At the concentration of 10%, fennel oil and trans‐anethole induced morphological deformation in the dead larvae such as shrunk bodies with dark colored integument. Regarding the pupicidal activity, fennel oil showed percentage inhibition rate (PIR) of 100% at the concentration of 10% while the same effect was achieved by trans‐anethole at concentration of 5%. On the contrary, fenchone did not show any pupicidal activity. Treatment of the third instar house fly larvae with LC5o of fennel oil, trans‐anethole, and fenchone significantly inhibited the acetylcholinestrase (AchE) when compared with the control untreated larvae. Additionally, the glutathione‐s‐transferase (GST) and malondialdehyde (MDA) production significantly increased in the larvae treated with trans‐anethole. The results of the present study indicate that the insecticidal activity of fennel oil was mainly attributed to the presence of trans‐anethole as a major constituent.

AbstractBackgroundEsophageal cancer is currently the eighth most common tumor in the world and a leading cause of cancer death. SULT2B1 plays crucial roles in tumorigenesis. The purpose of this study is to explore the role of SULT2B1 in esophageal squamous cell carcinoma (ESCC).MethodsThe expression of SULT2B1 and its clinicopathological characteristics were evaluated in ESCC cohorts. Bisulfite genomic sequencing and methylation specific PCR were used to detect the promoter hypermethylation of the SULT2B1 gene. The effects of SULT2B1 on the biological characters of ESCC cells were identified on functional assays. Subcutaneous xenograft models revealed the role of SULT2B1 in vivo with tumor growth. RNA‐Seq analysis and qRT‐PCR were performed to recognize the targeted effect of SULT2B1 on PER1.ResultsSULT2B1 was not expressed or at a low level in most patients with ESCC or in ESCC cell lines, and this was accompanied by poor clinical prognosis. Furthermore, the downregulation of SULT2B1 occurred in promoter hypermethylation. According to the functional results, overexpression of SULT2B1 could inhibit tumoral proliferation in vitro and retard tumor growth in vivo, whereas SULT2B1 knockdown could accelerate ESCC progression. Mechanistically, SULT2B1 targeted PER1 at the mRNA level during post‐transcriptional regulation. Finally, PER1 was verified as a suppressor and poor‐prognosis factor in ESCC.ConclusionsSULT2B1 loss is a consequence owing to its ability to promote hypermethylation. In addition, it serves as a suppressor and poor‐prognosis factor because of the post‐transcriptional regulation of PER1 in ESCC.
Afatinib and osimertinib in lung adenocarcinoma harbored EGFR T751_I759delinsS mutation: A case report
Authors: Fang Yueh‐Fu , Liu Ping‐Chi 
Published: November 2021

AbstractTyrosine kinase inhibitors (TKIs) of epidermal growth factor receptor (EGFR) are the standard treatment for lung cancer patients with activating EGFR mutation. The traditional direct polymerase chain reaction (PCR) has lower sensitivity in the detection of EGFR mutations in patient tissue samples. Whilst PCR amplification kits increase the sensitivity in detecting some types of EGFR mutations, not many types of rare mutations are found. Here, we report a patient who had lung adenocarcinoma harboring EGFR T751_I759delinsS mutation and had good response to afatinib initially and osimertinib after developing resistance to afatinib. This rare EGFR mutation was not detected by Scorpion and ARMS method but was found using the next‐generation sequencing method. There are less prospective trials in the treatment of lung adenocarcinoma with very rare EGFR mutations. Our case report could therefore provide clinical experience to the clinicians in the management of their patients.

AbstractBackground and AimsIn light of the accelerating drug overdose epidemic in North America, new strategies are needed to identify communities most at risk to prioritize geographically the existing public health resources (e.g. street outreach, naloxone distribution efforts). We aimed to develop PROVIDENT (Preventing Overdose using Information and Data from the Environment), a machine learning‐based forecasting tool to predict future overdose deaths at the census block group (i.e. neighbourhood) level.DesignRandomized, population‐based, community intervention trial.SettingRhode Island, USA.ParticipantsAll people who reside in Rhode Island during the study period may contribute data to either the model or the trial outcomes.InterventionEach of the state's 39 municipalities will be randomized to the intervention (PROVIDENT) or comparator condition. An interactive, web‐based tool will be developed to visualize the PROVIDENT model predictions. Municipalities assigned to the treatment arm will receive neighbourhood risk predictions from the PROVIDENT model, and state agencies and community‐based organizations will direct resources to neighbourhoods identified as high risk. Municipalities assigned to the control arm will continue to receive surveillance information and overdose prevention resources, but they will not receive neighbourhood risk predictions.MeasurementsThe primary outcome is the municipal‐level rate of fatal and non‐fatal drug overdoses. Fatal overdoses will be defined as unintentional drug‐related death; non‐fatal overdoses will be defined as an emergency department visit for a suspected overdose reported through the state's syndromic surveillance system. Intervention efficacy will be assessed using Poisson or negative binomial regression to estimate incidence rate ratios comparing fatal and non‐fatal overdose rates in treatment vs. control municipalities.CommentsThe findings will inform the utility of predictive modelling as a tool to improve public health decision‐making and inform resource allocation to communities that should be prioritized for prevention, treatment, recovery and overdose rescue services.

AbstractBackground and AimsThe individual‐level effectiveness of opioid agonist treatment (OAT) in reducing mortality is well established, but there is less evidence on population‐level benefits. We use modeling informed with linked data from the OAT program in New South Wales (NSW), Australia, to estimate the impact of OAT provision in the community and prisons on mortality and the impact of eliminating excess mortality during OAT initiation/discontinuation.DesignDynamic modeling.Setting and participantsA cohort of 49 359 individuals who ever received OAT in NSW from 2001 to 2018.MeasurementsReceipt of OAT was represented through five stages: (i) first month on OAT, (ii) short (1–9 months) and (iii) longer (9+ months) duration on OAT, (iv) first month following OAT discontinuation and (v) rest of time following OAT discontinuation. Incarceration was represented as four strata: (i) never or not incarcerated in the past year, (ii) currently incarcerated, (iii) released from prison within the past month and (iv) released from prison 1–12 months ago. The model incorporated elevated mortality post‐release from prison and OAT impact on reducing mortality and incarceration.FindingsAmong the cohort, mortality was 0.9 per 100 person‐years, OAT coverage and retention remained high (> 50%, 1.74 years/episode). During 2001–20, we estimate that OAT provision reduced overdose and other cause mortality among the cohort by 52.8% [95% credible interval (CrI) = 49.4–56.9%] and 26.6% (95% CrI =22.1–30.5%), respectively. We estimate 1.2 deaths averted and 9.7 life‐years gained per 100 person‐years on OAT. Prison OAT with post‐release OAT‐linkage accounted for 12.4% (95% CrI = 11.5–13.5%) of all deaths averted by the OAT program, primarily through preventing deaths in the first month post‐release. Preventing elevated mortality during OAT initiation and discontinuation could have averted up to 1.4% (95% CrI =  0.8–2.0%) and 3.0% (95% CrI = 2.1–5.3%) of deaths, respectively.ConclusionThe community and prison opioid agonist treatment program in New South Wales, Australia appears to have substantially reduced population‐level overdose and all‐cause mortality in the past 20 years, partially due to high retention.
Cysteine challenge test as a novel diagnostic tool to distinguish oral halitosis
Authors: Aydin Murat , Gunay Ismail 
Published: November 2021

AbstractBackgroundThe cysteine challenge test is often used to check the H2S production capacity of the mouth. Patients with oral halitosis group (n = 305) or non‐oral halitosis group (n = 191) and healthy individuals (control group, n = 102) were compared with each other to identify any possible relationship between initial and cysteine‐induced oral H2S concentrations.Subjects and MethodThe medical records of 598 participants were reviewed retrospectively. Oral H2S concentrations before (pre‐CR) and after cysteine rinse (post‐CR) with 5 mL of 20 mmol L‐cysteine solution for 30 s were compared.ResultsPre‐CR H2S concentrations were >0.8 ppm in 75.1% of oral group patients but less than <0.8 ppm in 87.3% of the non‐oral group and 86.9% of controls. After cysteine rinse, oral H2S concentrations exceeded 12 ppm in 72% of the oral halitosis patients but were lower in 88% of non‐oral group and 99% of controls. Whilst post‐CR/pre‐CR ratio was >12 in 74.5% of the oral group, it was <12 in 81.7% of the non‐oral group and 83.4% of controls.ConclusionCysteine challenge test can be used as a diagnostic tool to identify an individual's tendency to produce oral malodor, not only to quantify momentary halitosis level.
