Background

Substance use, sexual assault, and sexual risk behaviors are common among adolescents and are interrelated. Nearly 1 in 5 adolescents use substances before sexual encounters, placing these young people at risk for both sexual assault and sexual risk behaviors. Primary care visits present a unique opportunity to address multiple health risk behaviors.

Objective

Teen Well Check is a web-based integrated prevention program for substance use, sexual assault, and sexual risk behaviors with demonstrated usability and acceptability among patients and providers. The aim of this study was to conduct a pilot randomized controlled trial to assess feasibility.

Methods

Adolescents (n=123) aged 14 to 18 years from diverse backgrounds were recruited from primarily Medicaid-serving pediatric primary care clinics. Participants completed a baseline survey; were randomized to receive Teen Well Check or an assessment-only control; and completed 1-, 3-, and 6-month follow-up surveys. Feasibility was assessed in terms of recruitment and retention rates. Preliminary changes from baseline to follow-up periods were examined separately in the Teen Well Check and control conditions.

Results

We recruited 123 participants (Teen Well Check: n=61, 49.6%; control: n=62, 50.4%). Of the 61 participants assigned to the Teen Well Check condition, 55 (90%) completed the full program and viewed all intervention content. Of the 123 participants, 105 (85.4%) were retained across at least 1 follow-up period, and there was no difference in follow-up rates between the conditions (χ21=0.6; P=.43). The completion of Teen Well Check took an average of 6.2 (SD 5.8) minutes. Preliminary analyses revealed that there were significant reductions in perceived peer norms (descriptive norms) for substance use before sex across follow-ups among participants in the Teen Well Check condition (P=.001 from baseline to 6 months), whereas there were significant increases among participants in the control condition (P=.003 from baseline to 6 months). In addition, there were nonsignificant reductions in substance misuse risk from baseline to the 6-month follow-up among participants in the Teen Well Check condition (P=.16).

Conclusions

These findings support the feasibility of Teen Well Check delivery within pediatric primary care clinics. A randomized clinical trial is needed to assess efficacy.

Water Wave Velocity Potential on Sloping Bottom in Water Wave Transformation Modeling
Authors: Hutahaean Syawaluddin
Published: November 2023

In this research, we formulated the equation for water wave velocity potential on sloping bottoms. The resulting velocity potential equation for sloping bottoms closely mirrors that of flat bottoms, simplifying its application in sloping terrain scenarios. By exploring velocity potential on sloping bottoms, we derived conservation equations governing wave constant changes as waves transition from deep to shallow waters. These equations encompass the wave number conservation and energy conservation principles. Utilizing these conservation equations, we developed a comprehensive wave transformation model. The one-dimensional model focused on shoaling and breaking phenomena, while the two-dimensional model delved into refraction-diffraction, shoaling, and breaking. The model's framework allows for straightforward extensions, facilitating future advancements in the field.

Published: November 2023

Abstract: In our daily life we see so many situations where patients face many difficulties failing to find the hospital required for their needs. There are many situations where the patients are dead after going to the hospital because of unavailability of beds, surgeons and oxygen cylinders. Even if they find a hospital having these needs the distance would be more which in turn result in the death of the patient. To avoid this situation, we have developed a system where patients can have the information of the hospitals like number of beds available, oxygen cylinders and distance from ambulance to hospital. The system will collect the vital parameters of the patient, helps to check the criticality of the patient and chooses a hospital

Published: November 2023

As ações dos serviços da atenção primária à saúde (APS) são realizadas por uma equipe multiprofissional e direcionadas à população de um território definido, incumbindo-se de uma responsabilidade sanitária. Tal responsabilidade pode fazer com que os trabalhadores estejam susceptíveis a diversos fatores estressores, que podem interferir negativamente na sua saúde, nos relacionamentos e no desempenho das funções. Diante disso, o objetivo deste estudo foi realizar e avaliar uma estratégia de promoção da saúde para os trabalhadores da APS por meio das Práticas Integrativas e Complementares em Saúde (PICS). Trata-se de um relato de experiência de uma estratégia realizada em uma Unidade Básica de Saúde (UBS) de atuação de uma equipe de residentes multiprofissionais em atenção básica/saúde da família e comunidade da Prefeitura Municipal de Mossoró (RN). A estratégia contou com um momento de planejamento; um de execução, dividido em três encontros realizados entre maio e setembro de 2021, com aplicação das práticas de escalda-pés, auriculoterapia, meditação, ventosaterapia e massagem; e um de avaliação. Constatou-se que o escalda-pés, a auriculoterapia e a meditação foram as práticas mais empregadas. A estratégia demonstrou-se efetiva para a promoção da saúde aos trabalhadores por meio das PICS e exequível no âmbito da APS. Além disso, fortaleceu os vínculos entre eles e os instigou a se capacitar em PICS, o que repercute na qualificação da assistência aos usuários. No entanto, sugere-se que a gestão do município institua uma política municipal de PICS, para estimular ainda mais o desenvolvimento dessas práticas no Sistema Único de Saúde (SUS) local.

Published: November 2023

A atenção à saúde da criança em risco ao desenvolvimento tem se tornado fundamental no contexto das políticas públicas no Brasil. Todavia, o campo de práticas e as pesquisas revelam baixo alcance na prevenção e promoção em saúde, no âmbito da intervenção precoce. Os objetivos deste estudo foram descrever as ações existentes na Rede de Atenção à Saúde da criança com risco ao desenvolvimento, demonstrar as lacunas existentes no cuidado e traçar uma linha de cuidado integral, numa região de um Estado brasileiro. Trata-se de uma pesquisa- ação com realização de entrevistas direcionadas aos profissionais que compõem essa rede e aos responsáveis pelas crianças que são acompanhadas no centro especializado em reabilitação, local onde também se realizou análise de prontuários. Os resultados propiciaram a identificação de crianças com fatores/situações de risco ao desenvolvimento não visibilizadas pelos profissionais e/ou serviços e dificuldades de acesso à puericultura e seguimento nos serviços especializados. Nesses, observaram-se fragilidades nas práticas de prevenção e promoção de saúde dessas crianças. Esse estudo propõe e estimula a prática de ações contempladas nas políticas públicas destinadas a esse público e formação de equipe interprofissional para atendimento itinerante. Conclui-se que o cumprimento das políticas de saúde é fundamental para que crianças não fiquem à margem da assistência e invisíveis no percurso do seu desenvolvimento.

Published: November 2023

Purpose: Tongue base reduction surgery is the only minimally invasive
technique that can be performed under local anesthesia as an outpatient
procedure, especially to treat obstructive sleep apnea caused by
hypopharyngeal obstruction.Studies reported that various devices could
be used for tongue base reduction, but comparisons of these methods are
limited in the literature. Our study aimed to compare the histological
effects of tongue base reduction methods performed with the Celon
radiofrequency, monopolar cautery, Coblator, and Sutter devices on the
tissue. Methods: This study included 23 female rats (aged 4–8 months).
Rats were divided into 5 groups. Tongue base reduction was performed
with monopolar cautery in the first group(5 rats), with radiofrequency
in the second group(5 rats), with the Coblator in the third group(5
rats), and with the Sutter in the fourth group(5 rats). The fifth group
was the control group which consisted of 3 rats. The rats tongues were
resected for histological examination 1 week after procedures. Results:
While the highest amount of fibrosis was seen in the Sutter group,
fibrosis was also higher in the Coblator group. A significant difference
was observed in all groups when compared with the control group
regarding tissue thickness. While the average tissue thicknesses of the
monopolar, rf, and Coblator groups were almost the same, the highest
tissue reduction, was in the Sutter group. Conclussion: Although we
observed that all the methods we used were safe, the method that caused
the most fibrosis and tissue reduction was the Sutter.

Published: November 2023

We obtain, by generalizing the extension of the continuous theorem of Ge
and Ren and constructing suitable Banach spaces and operators, two
results about the existence of solutions for fractional differential
equations with resonant p-Laplacian and functional boundary conditons.
Meanwhile, the dimension of the kernel for a fractional differential
operator with boundary conditions is two, which generalises and enrichs
some known results. An novel example is also given to illustrate the
existence theorem. Mathematics Subject Classification. Primary 34A08;

Usefulness of last generation Insertable Cardiac Monitors in the diagnosis of unexplained syncope
Authors: Arabia Gianmarco , Colangelo Maria , Borrello Francesco , Curnis Antonio , Ciconte Vincenzo Antonio , Francesco Arabia
Published: November 2023

Aims: Guidelines recommend insertable cardiac monitor (ICM) in
the early phases of the evaluation of unexplained syncope (US) syncope,
when an arrhythmic etiology is suspected. We examined the diagnostic
yield of the last generation ICM (LG-ICM) to establish the causes of US,
by assessing in the clinical practice the incidence of: relevant
arrhythmia diagnosis, syncope recurrences and CM-guided cardiac
electronic device (CIED) implantation. We investigated also baseline
patient characteristics associated to an increased risk of relevant
arrhythmias and of syncope recurrence. Methods: Data
prospectively collected from consecutive patients receiving LG-ICM for
investigation of US or presyncope in our institution between November
2020 and January 2023 were analyzed. Result: A total of 109
patients (mean age 64.4 ± 16.1 years, 40.4% women) with US or
pre-syncope episodes underwent implantation of the LG-ICM. During a mean
follow-up of 11.7 ± 8.1 months, LG-ICM diagnostic yield was 42% . In
particular, LG-ICM detected cardiac arrhythmias in 29 (27%) patients
(in 6 out of them during a syncope recurrence) and to exclude the
arrhythmic origin of the syncope in additional 19 (17%) patients.
LG-ICM guided the implantation of a CIED in 16 (15%) US patients, due
to the diagnosis of asystole or severe bradycardia. Age ≥ 65 years
(p=0.012) and atrial arrhythmia history (p=0.004) are significant
independent predictors of arrhythmic diagnoses performed by LG-ICM,
while CAD is predictor of syncope recurrence (bordering on statistical
significance, p=0.056). Conclusions The diagnostic yield of
LG-ICM in US syncope is comparable to those of ILR and previous
generation ICM. The advantages of LG-ICM should be sought in lower
hospital workload necessary to manage ICM data. Age ≥ 65 years and
atrial arrhythmia history are independent predictors of significant
ICM-detected arrhythmias.

Objective We sought to determine whether patients are capable and
willing to self-administer and interpret an EldonCard test to determine
their Rh status. Design Cross-sectional study Setting Ambulatory
obstetrics and gynecology clinic in Honolulu, HI Population
English-speaking pregnancy-capable people aged 14-50 who did not know
their blood type and had never used an EldonCard Methods Participants
independently completed EldonCard testing, determined their Rh type and
answered a survey on feasibility and acceptability. Separately, a
blinded clinician recorded their interpretation of the participant’s
EldonCard. When available, we obtained blood type from the electronic
health record (EHR). Main Outcome Measures Rh type agreement between
participant, clinician and EHR, as well as participant comfort and
acceptability of testing Results Of the 330 total participants, 288
(87.3%) completed testing. Patients and clinicians had 94.0% agreement
in their interpretation of the EldonCard for Rh status. Patient
interpretation had 83.5% agreement with EHR while clinician and EHR had
92.3% agreement. Sensitivity of EldonCard interpretation by patient and
clinician was 100%. Specificity was 83.2% for patients and 92.2% for
clinicians. Two patients had Rh-negative blood type in the EHR. The vast
majority of participants found the EldonCard testing easy (94.4%) and
felt comfortable doing the testing (93.7%). Participants with lower
education levels felt less confident (p=0.003) and less comfortable with
testing (p=0.038), however, their ability to interpret results was
similar to others (p=0.051). Conclusions Patient-performed Rh typing via
the EldonCard is an effective and acceptable option for patients, and
could be used as a primary screening test for Rh status. Funding The

Spleen involvement at diagnosis of multiple myeloma: a case report and literature review
Authors: Fiorini Alessia , Chavez Maria Gabriela , Panichi Valentina , Ranucci Valentina , Remotti Daniele , Tarnani Michela , Montanaro Marco , Latagliata Roberto , Andriani Alessandro
Published: November 2023

Background Multiple Myeloma (MM) is more often characterized by clonal
plasma cell proliferation restricted to the bone marrow. However, a
small percentage of patients with MM develops extramedullary disease
(EMD): this type of localization is found in 1.7-4.5% of the newly
diagnosed MM (ND/MM) and in 3.4-10% of patients with relapsed or
refractory disease (RR/MM) and seems to have a bad prognostic impact. In
the present report, we describe a very rare case of splenic involvement
in a patient with ND/MM. Case A 72 years old female was referred in June
2022 with asthenia and abdominal pain. At physical examination, spleen
enlargement was detected, with anemia (Hb 10.5 g/dL) and
thrombocythopenia (48 x 109/L). Abdominal echography confirmed spleen
enlargement (20 cm of longitudinal diameter). Blood tests showed free
light chain alteration with a λ/κ ratio of 800. Marrow aspiration showed
60% of λ-restricted immature plasma cells: p53 expression was present
in 91% of elements. PET CT scan revealed multiple focal areas of bone
increased metabolic activity and a widespread positivity of the spleen
with focal areas of higher uptake. Diagnosis of MM with splenic EMD was
done and Dara-VMP regimen was started. After the first cycle of therapy,
a marked reduction of the spleen size was observed with increase of both
Hb level and platelet count. After the 2nd cycle of therapy, however,
there was evolution in plasma cells leukemia: Vd-PACE regimen was thus
started, but after the 2nd cycle she died in October 2022 from septic
shock and multiorgan failure. Conclusions Our very rare case of ND/MM
with spleen involvement confirms the aggressive behaviour of EMD, with
negative prognostic factors (p53 mutation) and failure to frontline
highly effective therapy. In the other few cases of spleen involvement
reported, however, there were only scarce details about response: as a
consequence, collection of similar cases is warranted to fully
understand clinical features and possible alternative approaches for
these extremely rare patients.

Published: November 2023

Facial expression is an important way to reflect human emotions.
Analyzing facial movements is an effective means of understanding
expressions. In this paper, a classic optical measuring method called
stereo digital image correlation (stereo-DIC or 3D-DIC) is employed to
analyze the deformation of facial expressions. The forming processes of
six basic facial expressions of certain experimental subject are
analyzed through the strain calculated by 3D-DIC. Based on the
calculated results, a novel deformation analysis strategy is introduced
to dissect the details of facial expressions. The observations
especially deal with the areas that deform first and the strain
variation of the most active areas on the human face in the expressions.
The presented investigations demonstrate the superior performance of
3D-DIC in the quantitative analysis of facial expressions. Such
measuring method and analytical strategy might have potential value to
further reveal the underlying human emotional fluctuation.

The aim of the study is increasing the efficiency of surface runoff drainage systems` performance in order to prevent flooding of urban areas due to the climate change in conditions of increasing number and intensity of heavy rains taking into account the uneven distribution of rainfall over areas. Numerous studies on the uneven distribution of heavy rains over the area are heterogeneous and contradictory, which indicates insufficient knowledge of the issue. Thus, there arises a need for experimental and theoretical research to refine the coefficient K, which takes into account the unevenness of rainfall over the area. As a result of the study of the value of the correction factor K to the estimated costs in sewerage networks, recommendations are presented for updating the correction factor in SP 32.13330.2018 in accordance with the results of these studies.

Agricultura ecuatoriana en medio de la pandemia. Efectos de la política pública en el productor agrícola
Authors: Vasconcellos Fernández Nicolas Alberto
Published: November 2023

La pandemia del COVID-19 ocasionó el cierre total del Ecuador en marzo del 2020. Dicho cierre involucró la reducción del flujo productivo y comercial de la agricultura. Este estudio se enfoca en el análisis reflexivo de la influencia de las políticas públicas sobre el sector agrícola y cómo una situación socioeconómica crítica como la generada por la pandemia puede evidenciar y agudizar inobservancias del Estado sobre la soberanía alimentaria. El estudio realizó una revisión de las políticas implementadas para lidiar con el COVID-19 en Ecuador y su impacto en la producción campesina. Los resultados muestran que el productor se vio imposibilitado de comerciar sus productos y el consumidor de adquirirlos. Se concluye que hoy, más que nunca, sobresale ante el Estado la importancia del productor campesino, quien fue el más afectado con las restricciones de movilización a nivel nacional durante el estado de emergencia. Estas condiciones denotan políticas estatales parcializadas al beneficio del agroexportador y la industria alimenticia empresarial, poniendo en una frágil situación a la agricultura campesina en situaciones de emergencia sanitaria cuando la prioridad es alimentar a la población nacional y fortalecer el sector rural que la suple.
Reduction of Pollutants in the Tanning Industry Using the Reverse Tanning Method against the Physical Properties of Leather
Authors: SUSANTO Heru Budi , JUHANA Swatika
Published: November 2023

This study aims to tan the skin with reverse tanning based on the order of pH, thereby reducing the use of chemicals and water due to the pH regulation process. The reverse tanning method will result in a faster tanning process and reduce the use of many chemicals, so that the pollutant load released from the tanning process will be much reduced. Conventional leather tanning is carried out through many processes starting from the BHO (Beam House Operation) process, tanning, post-tanning, and finishing; this process is carried out through a 14-15 step process that produces a large number of pollutants. This is because in conventional leather processing a lot of pH adjustment processes are carried out that go back and forth. In this study the leather processing steps were ordered based on the pH of the tanning process, the chemicals and the pH of the process were regulated by the sequence of the process steps to avoid some repeated acidification and basification/neutralization as in conventional leather processing. The process begins with soaking, liming, fleshing, deliming, tanning, dyeing, fatliquoring, and chrome tanning. This process begins with an alkaline pH of 11 and ends with an acidic pH of 3.8. Chrome tanning is done with variations in the amount of chrome of 2%, 3%, 4%. The results showed that leather with 4% chromium produced the highest Ts of 103 °C, tensile strength of 39.86 N, tearing strength of 13.19 N/mm, seam strength of 12.8 N/mm, elongation of 46.87%, Cr content (VI) 1.68 ppm. These results have met the standard ISO/TR 20879:2007 Footwear. The reverse tanning process with a process from high to low pH without adjusting the pH back and forth by adding solutions and salts means reducing liquid waste in the leather tanning process. So, this process can reduce the amount of liquid waste or pollutants.

Published: November 2023

Chrome tanning is an essential process to convert raw animal skin into leather, in which collagen, as the main structure of leather, is stabilized against degradation through cross-linking using chromium, consisting of two steps: penetration and basicity. However, the uptake of chrome in leather still needs to be improved. The purpose of this study was to find the best heating time in the chrome tanning process by thermal analysis. Pickled sheepskin was used as raw material for the chromium tanning process. The samples were varied into four categories: heated at the penetration stage of the tanning process (Initial Heating), heated at the basification stage of the tanning process (Final Heating), and heated both at the penetration and basification stage (Continuous Heating). In this study, the thermal stability of wet blue leather was evaluated by shrinkage temperature behavior (Ts), thermogravimetry analysis (TGA/DTG), and differential scanning calorimetry (DSC). The tanning efficiency was measured by Cr2O3 content. The results demonstrated that wet blue samples heated continuously shows better thermal characteristics. In conclusion, the results can be used for finding the best possible technique for the leather tanning process using chrome salts to gain thermal stability.

Published: November 2023

Two antimicrobial gels, formulated with natural biopolymers (collagen and chitosan), limonene, and an imidazole derivative, were subjected to cytotoxicity tests. In these two compositions, the limonene content was 0.4% and 0.67%. The cytotoxicity tests were performed in vitro, using MTT methodology, and a standardized human normal cells line, HUVEC type. These cells were exposed to different levels of gel concentrations in the culture media. The final concentration of each gel type in culture media was situated between (0-0.125) μL/mL. The cell viability was determined after 24, 48 and 72h of exposure. The analyses showed that after 24h of exposure, the viability of the cells is greater than 91%, after 48h the viability is greater than 80%; after 72 h of exposure, the viability of the cells is greater than 74%. These values reveal that both selected gels exhibit no cytotoxicity for the normal cell line.

Insole construction is considered to be related to stability in sports, and custom-made insoles with their scientifically tailored approach and effective construction are considered to be the main means of adjusting posture and reducing risk in sports. We have designed a non-100% full-fit design insole (CDI) with an arch support insole and metatarsal liner to determine whether this insole can be adapted to lower limb kinematics. Eleven healthy volunteers participated in this randomized crossover test in which a motion capture and 3D gait analysis system was used to measure the subjects’ lower limb kinematic data while exercising at different slopes and speeds wearing three different insoles: CDI, control Insole (CI) and arch support insoles (ASI). In addition, the experiments introduced the speed and slope factor, analyzed the extent to which speed slope affects joint angle using UNIANOVA, and compared the performance differences between the three insoles in different planes in pairs. The CDI inhibited ankle dorsiflexion and knee flexion in the sagittal plane; in the frontal plane, CDI reduced knee adduction and hip abduction angles. There was a statistically significant difference (p < 0.05) between the change in joint angle and the velocity slope. Slope*speed had a greater effect on the ankle and knee joints (%sig>30%). The results show that the CDI has better kinematic adjustability in the ankle and knee joints due to its superior insole design approach. Therefore, wearing the CDI may be an effective way of reducing risks in sports.

Áreas destinadas à conservação desempenham papel essencial na regulação global do clima, pois, as florestas são o principal sumidouro de carbono terrestre, uma vez que, capturam dióxido de carbono da atmosfera e armazenam o carbono em sua biomassa, principalmente na madeira. O objetivo deste trabalho foi analisar a dinâmica nos estoques de volume, biomassa e carbono em área total da Bacia Hidrográfica do Rio Iguaçu e em áreas especiais, como Matas Ciliares, Unidades de Conservação, Terras Indígenas e Assentamentos Rurais, entre os anos 2000 e 2015. Foram utilizados arquivos vetoriais da cobertura florestal da bacia para os anos-base para a estimativa das variáveis por formação florestal e estágio sucessional. A Bacia Hidrográfica do Rio Iguaçu como um todo foi sumidouro de carbono nos 15 anos analisados, com aumento nos estoques na ordem de 14% para V, AGB, C e CO2eq (sequestro de 116.173.629,91 t de CO2eq) no período. As áreas especiais foram sumidouro de carbono, sendo que as Unidades de Conservação estocaram mais carbono (11,72% do total da bacia) e Matas Ciliares sequestraram mais carbono (3,54% do total da bacia).

Governance, Investors Motivations and Foreign Direct Investment Inflow in Selected African Countries: Does John Dunning’s Eclectic Paradigm Matters?
Authors: Aberu Felix
Published: November 2023

Over the years, studies have focused on the implications of institutional quality as a key factor of FDI inflows into Africa and how it influences the economic processes of various African countries. However, in the studies on Africa, investors’ motivations as determinants of foreign direct investment inflows into African regions are grossly understudied and yet determined. As a result, there is a need to investigate the impact of FDI inflows on African countries, as well as the implications of home and host country investment phenomena. The study employs ex-post-facto research using panel data obtained from different World Bank publications; world development indicators, and the Transparency Index database from 1997 to 2022. The System Generalized Method of Moments (SGMM) was used to examine the data. The results reveal that governance and investor motivations have a negative impact on each other; the effect of the interacted variables is less than the total of the impacts of governance and investor motivations separately. Therefore, FDI in the selecte3d African countries will decline by 7.5 points for every unit increase in the level of poor governance and investor motivations, and this validates the locational assumption of John Dunning Eclectic Paradigm with the proposition that FDI inflows is a function of the home and host investment phenomena As a result, we recommend that African governments implement Regulatory reform, market reform, complete streets policies, and contingency-based planning that are FDI inflow induced.
Forensic Science Integration in Legal Education: A Paradigm Shift for Strengthening Legal Expertise in Pakistan
Authors: Ali Muhammad Imran
Published: November 2023

The objective and scientific interpretation of evidence provided by forensic science is a crucial component of the contemporary judicial system. In Pakistan, forensic science education is not a part of the required curriculum for obtaining a Bachelor of Law (LL.B.) degree. Lawyer’s knowledge of the scope and limits of forensic research is hindered by the absence of a thorough forensic science component within law school. This, in turn, may obstruct the proper use of forensics in court procedures, which can slow down the distribution of justice. Forensic science education offers numerous benefits, including a holistic understanding of law and forensic science, interdisciplinary skills development, enhanced collaboration between lawyers and experts, and the development of specialized lawyers for handling complex cases. Law students may benefit from a deeper grasp of the scientific processes involved in criminal investigation, evidence collecting, preservation, analysis, and presentation by taking forensic science courses. Future lawyers will benefit from this understanding while trying cases, challenging expert testimony, and arguing on behalf of their clients. This article addresses the advantages, problems, and possible tactics for integrating forensic science into the LL.B. curriculum in Pakistan.
The historic greenhouses of the Greifswald Botanic Garden (Mecklenburg-Western Pomerania, Germany) – rescued in the nick of time
Authors: König Peter
Published: November 2023

The historic greenhouses of the University of Greifswald, built between 1884 and 1886 and covering an area of almost 300 m², are characterised by their riveted frame construction typical of the era. After almost 130 years of uninterrupted use, they were briefly on the brink of collapse in 2014 because damage caused by corrosion had reached a critical level. The State Monument Preservation Office campaigned strongly for the greenhouses, so that the university, with the support of the State of Mecklenburg-Western Pomerania and other sponsors, was ultimately able to successfully carry out the restoration. The costs are expected to amount to around €4.3 million. The construction work undertaken on the tropical, palm and cycad houses guarantees that valuable plant collections will be preserved and that more extensive growth phenomena and ecological relationships can be demonstrated in the future.
Raising Rarity: Creating meaningful and sustainable conservation outcomes through community-based outreach.
Authors: Hirst Megan , Arnott John , Larke Russell
Published: November 2023

A priority in plant conservation science is the identification of species at risk of extinction, allowing for conservation efforts to be focused on those that are most critically endangered to prevent their loss. A 2023 revision of threatened plants in Victoria found that 1,557 species remain under direct threat of extinction, despite conservation work being undertaken across the state to safeguard both individual species and plant communities. Although conservation efforts are fundamental to the protection of our flora, the persistently high number of threatened species illustrates a need to reimagine the way in which we approach conservation. Central to this is a need to engage more people across a broader cross-section of the community so that they can contribute to initiatives that effectively reduce the number of species at risk.Raising Rarity is a community-based outreach programme run by Royal Botanic Gardens Victoria (RBGV). It is designed to actively engage distinct sectors of the Victorian community in local plant conservation. The programme acknowledges that although the expertise provided by RBGV in areas that include conservation horticulture, seed ecology, population genetics, outreach and education is critical to plant conservation efforts, the engagement and involvement of the broader community is fundamental to creating sustainable plant conservation solutions. Raising Rarity achieves this by working with volunteers, school groups, regional botanic gardens, local councils and members of the nursery industry to grow and display rare and threatened Victorian plants in accessible horticultural settings. The initiative aims to increase public knowledge, awareness and hands-on involvement in plant conservation.There are four key components to the Raising Rarity programme: (1) school outreach; (2)local government outreach; (3) botanic gardens outreach in an initiative called Care for the Rare; and (4) commercialisation of an RBGV rare plant collection. This article provides an overview of each of these components and outlines future objectives for the Raising Rarity programme.
